Description

{SYSTEM FOR MANHOLE COVER}

The present invention relates to a manhole cover system, and more specifically, to a manhole cover system that, when installing a cover to prevent a person from falling into a sewer passage, allows necessary wires to pass through during construction, makes the cover light in weight so that workers entering and exiting the passage can move easily, and prevents a person from falling out during construction.

Manhole covers are generally installed to prevent people from falling into dangerous situations when entering and exiting a sewer pipe for maintenance work.

Additionally, manhole covers are made so heavy that they cannot be moved by one or two people to prevent them from being dislodged by people or cars passing over them.

Accordingly, when working on a sewer pipe, the manhole cover is moved completely to the side to secure a passage and continue the work, but even if a work sign is installed, there is a disadvantage in that there is a risk that a person passing over the passage may fall.

In addition, when working with a manhole cover covered to prevent people from falling in, there was a disadvantage in that the electricity needed for the work could not be used.

In addition, manhole covers that have once covered a passage are heavy, so moving them again requires a lot of force and time.

Accordingly, active research and development is being conducted in the industry to resolve the above-mentioned problems of manhole covers and enable the use of more effective manhole covers.

The present invention was created to solve the problems of the prior art as described above, and the purpose of the present invention is to provide a manhole cover system that prevents people from falling out when working on sewer pipes by using a lightweight manhole cover, enables easy installation and removal, and forms an opening through which wires can pass, so that wires used during sewer pipe work can be used safely.

A manhole cover system according to one embodiment of the present invention may include a manhole cover mounted on a manhole for the entry and exit of equipment or people, comprising: a cover portion mounted on the manhole; at least one handle portion formed on the cover portion; an anti-slip portion formed on an upper surface of the cover portion; and an opening portion which is a predetermined space through which an electric wire used in sewage pipe construction can pass.

Specifically, the opening may be formed such that an outermost part of the cover part is open.

Specifically, the cover portion may be formed of a material that includes at least a portion of aluminum.

Specifically, the lower surface of the cover part may further include a reinforcing member formed in a ‘+’ shape.

Specifically, the reinforcing member may include an ‘ㄱ’ shaped angle formed from an end of the cover member.

Specifically, it may further include an anti-beam guard formed on at least a portion of the outermost surface of the cover portion.

Specifically, the above-mentioned anti-beam guard part can be formed of a rubber material.

Specifically, the handle portion is formed so as to be able to pass through the cover portion and may be capable of a predetermined movement.

A manhole cover system according to one embodiment of the present invention has the effect of preventing a person from falling in by being installed in a passage leading to a sewer pipe.

Additionally, since it is made of light metal, it has the effect of allowing it to be moved easily and quickly to form a passage during construction.

In addition, by forming an opening in the manhole cover, there is an effect of being able to cover and open the manhole cover while protecting the wires installed in the passage during construction.

The effects that can be obtained from the disclosed embodiments are not limited to the effects mentioned above, and other effects that are not mentioned will be clearly understood by those skilled in the art to which the disclosed embodiments belong from the description below.

The purpose, specific advantages and novel features of the present invention will become more apparent from the following detailed description and preferred embodiments in conjunction with the accompanying drawings. In this specification, when adding reference numerals to components in each drawing, it should be noted that, as much as possible, the same components are given the same numerals even if they are shown in different drawings. In addition, in describing the present invention, if it is determined that a detailed description of a related known technology may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

The following detailed description will be given in detail together with the drawings illustrated below.

First, before explaining the manhole cover system of the present invention, let's look at conventional manhole covers.

Conventional manhole covers (lid) are installed at the top of vertical passages that connect the ground and underground for maintenance of water pipes, sewer pipes, underground electric cables, etc., to prevent the spread of odors in the pipes and to prevent people from falling into the passage.

In addition, the above passage refers to a facility through which people enter and exit for inspection, cleaning, and connecting and joining pipes within the pipeline.

These passages are installed in the middle of the pipeline because if they are not built, maintenance will be very difficult.

However, when a person enters or exits through the above passage, the manhole cover must be removed, and the manhole cover is manufactured to be strong enough not to be damaged, and is mostly manufactured from concrete or cast iron.

Manhole covers made of concrete or cast iron are very heavy, requiring a lot of manpower to move them for work. As a result, once they are moved, they are often left unclosed until the work is completed.

Accordingly, there are frequent cases of people falling into open passageways or dropping objects, resulting in injury.

Additionally, even if a manhole cover is placed during work, there may be cases where the use of wires, etc. used for work is restricted.

The present applicant has conducted research to resolve the shortcomings and problems of conventional manhole covers and developed the manhole cover of the present invention. Hereinafter, the manhole cover according to the present invention will be described in detail.

FIG. 1 is a drawing schematically illustrating a use embodiment of a manhole cover according to an embodiment of the present invention, FIG. 2 is a drawing schematically illustrating an upper surface of a manhole cover according to an embodiment of the present invention, FIG. 3 is a drawing schematically illustrating a lower surface of a manhole cover according to an embodiment of the present invention, and FIG. 4 is a drawing schematically illustrating a cross-sectional view of a manhole cover having a reinforcing bar formed according to an embodiment of the present invention when in use.

As illustrated in Fig. 1, a manhole cover (1) of a manhole cover system according to an embodiment of the present invention serves as a cover that covers a passage connecting the underground and the above ground.

According to one embodiment of the present invention, a manhole cover (1) is a manhole cover (1) that is installed in a manhole for the entry and exit of equipment or people, and may include a cover part (10) that is installed in the manhole; at least one handle part (20) formed on the cover part (10); and an anti-slip part (30) formed on an upper surface of the cover part (10); and an opening part (40) that is a predetermined space through which an electric wire used in sewage pipe construction can pass.

The above cover part (10) may have the same or similar size as the manhole so that it can be installed in the manhole.

In addition, the cover part (10) may have the same shape as the shape of the manhole. For example, it may be formed in various shapes such as circular, square, and triangular, but is not limited thereto.

The above cover part (10) can prevent equipment or people from falling into the manhole.

In addition, the cover part (10) may be formed of aluminum and may be easily moved by a person's hand, but is not limited thereto.

The above aluminum is a silvery white, light, soft metal that is easy to process and light. It is harmless to the human body, so it is widely used in construction, chemicals, and household products.

The cover part (10) formed of aluminum as described above can be easily moved with less manpower, unlike the existing manhole cover (1), so that when a worker enters the manhole, a worker waiting on the ground can easily close it.

In addition, workers who have entered the above-mentioned underground area can easily move around inside when they come out.

Even if a worker who has gone down to the above-mentioned underground encounters an emergency situation, the cover part (10) can be easily removed to enable rescue operations to continue.

Since the above cover part (10) has a size similar to that of the manhole, it may be difficult for a worker to remove it because there is no gap with the manhole.

At this time, a handle part (20) may be provided so that the cover part (10) can be easily moved.

The above handle part (20) is formed on the cover part (10), and it is preferable that two or more are formed, but this is not limited thereto.

The above handle part (20) enables the manhole cover (1) to be easily moved. For example, the manhole cover (1) is generally formed flat with the ground or formed below the ground, and in such a case, when there is no space formed between the manhole and the manhole cover (1) for a hand to enter, making it difficult to move, the handle part (20) can be held and easily pulled out.

The above cover part (10) is formed to cover the manhole and is formed to pass over the upper surface of the cover part (10).

However, since the cover part (10) is formed of aluminum, there is a possibility that the mover may slip.

To prevent this, the cover part (10) may have an anti-slip part (30) formed on the upper surface.

The above anti-slip part (30) may have a shape in which a portion protrudes upward from the cover part (10).

Specifically, it may be formed so that diagonal lines intersect, but is not limited thereto.

Referring to Fig. 2, the opening (40) may be formed on one side of the cover part (10) that is installed in the manhole. The opening (40) may have a size that does not allow a person's foot to fall through, and may be a size that allows wires or ropes used in the manhole to pass through, but is not limited thereto.

According to one embodiment of the present invention, the opening (40) may be formed so that one end of the cover (10) is opened.

The above opening (40) may be formed so that the wire can pass through, and the cover part (10) may be formed so that it can be removed from the manhole while the wire is passed through.

To this end, the opening (40) may be in a shape in which the outermost part of the cover part (10) is open. As such, the cover part (10) with the outermost part open may be able to be removed from the manhole while the wire is passed through.

In addition, if additional wires are needed while the cover part (10) is installed in the manhole, the cover part (10) can be removed from the manhole and then the wires can be added.

According to one embodiment of the present invention, the cover part (10) may be formed of a material that contains at least a portion of aluminum.

The above cover part (10) is formed lightly and has the characteristic of being able to move easily and quickly. For this purpose, the cover part (10) may be formed of a light material.

In particular, when formed with the above aluminum, it is very light and strong enough for a person to climb on, can be easily alloyed with other metals, and can be easily transformed into various shapes by utilizing the high ductility characteristics.

Accordingly, the cover part (10) is preferably manufactured from a light and strong aluminum alloy that can easily form the opening (40), but is not limited thereto.

According to one embodiment of the present invention, the opening (40) may be in a ‘ㄷ’ shape.

The above opening (40) may be provided in various shapes such as circular or polygonal.

Among them, the one equipped with the above ‘ㄷ’ shape may be the most desirable.

When the above manhole cover (1) is installed, a portion of the opening (40) may be covered by the manhole.

In such cases, there may not be enough space to use the above wire. In order to secure enough space, it is provided in a shape that is sunken inward, and among them, a square shape may be the most preferable.

The opening (40) provided in the above square shape makes it easy to manufacture a mold when manufacturing the manhole cover, minimizes waste of materials, and can be manufactured at a lower cost than other shapes.

In addition, when using the above wire, if the shape of the opening (40) is circular or triangular, the cover part (10) may come out of the manhole when the wire moves. However, if the opening (40) is provided in a 'ㄷ' shape, the cover part (10) can rotate in one direction and protect the wire even if the wire moves.

According to one embodiment of the present invention, a reinforcing member (50) formed in a ‘+’ shape on the lower surface of the cover member (10) may be further included.

The above reinforcing member (50) may be formed at the bottom of the cover member (10) installed in the manhole to prevent it from easily collapsing when a worker steps on it or a car passes by.

Specifically, the reinforcing member (50) may be in a '+' shape. The reinforcing member (50) may be in an optimal shape that can withstand the load applied to the cover member (10) while distributing it to the entire cover member (10) as much as possible, but is not limited thereto.

Additionally, it can be, but is not limited to, an 'll' shape or an 'o' shape.

According to one embodiment of the present invention, the reinforcing member (50) may include an ‘ㄱ’ shaped angle (51) formed from an end of the cover member (10).

The above cover part (10) is configured to be installed in the manhole, and the reinforcing member (50) is formed on the lower surface of the cover part (10). The manhole cover (1) may be formed such that the reinforcing member (50) directly touches the manhole.

The above reinforcing member (50) is formed with a structure in which a portion of the end of the reinforcing member (50) must fully withstand the load transmitted to the manhole cover (1).

That is, the structure is such that each end of the above '+' is in direct contact with the above manhole and supports the load.

The above reinforcing member (50) may be subject to severe wear due to friction with the manhole, and in severe cases, may become distorted and block a portion of the opening (40).

To prevent this, the reinforcing member (50) may include an ‘ㄱ’ shaped angle (51).

Specifically, the 'ㄱ' shaped angle (51) may be formed at each of the four ends of the reinforcing member (50).

The 'ㄱ' shaped angle (51) that is in direct contact with the manhole may be provided in a flat shape with the lower part of the cover part (10).

The cover part (10) and the 'ㄱ' shaped angle (51) provided in a flat shape as described above come into contact with the manhole at the same time, so that the load applied to the manhole cover (1) can be evenly distributed.

According to one embodiment of the present invention, the cover part (10) may further include an anti-beam guard part (60) formed on at least a portion of the outermost part.

The above cover part (10) may be formed of aluminum and may be characterized by being thin. The above cover part (10) may be worn due to friction with the manhole, and when worn, may have a sharp shape.

The above cover part (10) may damage surrounding objects when moved.

To prevent this, the above-mentioned anti-beam guard part (60) may be provided.

Specifically, the anti-beam guard part (60) may be formed along the outermost part of the cover part (10). That is, it may be formed in a part that can be replaced by coming into contact with the manhole.

In this way, the provided anti-beam guard (60) prevents direct contact between the manhole and the cover (10), thereby preventing the cover (10) from being worn.

Conversely, it is possible to prevent the manhole from wearing out.

According to one embodiment of the present invention, the anti-beam guard part (60) may have a shape in which the portion where the 'ㄱ' shaped angle (51) is formed is removed.

The part where the above 'ㄱ' angle is formed may have a height difference with the cover part (10). The anti-beam guard part (60) having a height equal to the height difference may be formed and offset the height difference.

In conclusion, the 'ㄱ' shaped angle (51) and the anti-beam guard part (60) have the same height, and can evenly receive the load applied from the upper part of the cover part (10) when in contact with the manhole.

According to one embodiment of the present invention, the anti-beam guard (60) may be formed of a rubber material.

The above-mentioned anti-beam guard part (60) is formed to prevent the manhole and the cover part (10) from wearing out due to friction.

At this time, rubber material can be used as the most suitable material, but is not limited to this.

The above rubber can be suitable because it can prevent wear from friction between the metals and prevent the manhole cover (1) from moving while it is seated in the manhole.

Additionally, since it is easy to install and remove, it can be easily replaced when it needs to be replaced due to continuous use.

According to one embodiment of the present invention, the handle part (20) is formed so as to be able to pass through the cover part (10) and can be moved in a predetermined manner.

When the above handle part (20) is used, it can be formed to protrude from the upper surface of the cover part (10) so that the user can easily hold it.

In addition, when the handle part (20) is not in use, it is formed to protrude from the lower surface of the cover part (10) so that a car or person passing over the upper surface of the manhole cover (1) can pass by without getting caught.

The handle part (20) for operating as described above can be moved while passing through the cover part (10).

Specifically, the handle part (20) may be a square-shaped frame. In addition, at least one hole may be formed in the cover part (10), and both sides of the frame of the handle part (20) may be formed to pass through the hole, so that movement to the top and bottom of the cover part (10) is possible.

That is, movement may be restricted due to blockage by a portion of the handle portion (20) other than the portion passing through the hole.

Although the present invention has been described in detail through specific embodiments, this is intended to specifically explain the present invention, and the present invention is not limited thereto, and it will be apparent that modifications or improvements can be made by those skilled in the art within the technical concept of the present invention.

All simple modifications or changes of the present invention fall within the scope of the present invention, and the specific scope of protection of the present invention will be made clear by the attached utility model registration claims.
