Description

The invention relates to devices for collecting and draining rain and melt water from ground and road surfaces and can be used in the improvement of yards, squares, gardens, parks, for example, for the formation of pedestrian areas, sidewalks, bike paths, etc.

Linear drainage is a system of buried gutters (drainage channels, trays), which are usually closed from above with protective and decorative drainage gratings.

Fastening the grating to the drainage channel tray is one of the most important components of the rain and melt water collection and drainage system.

The simplest and most common way of attaching the grating to the drainage channel tray is bolting. For this purpose, holes are made in the lattice along the longitudinal edge for bolts, and threaded holes are made in the drain channel in the planes on which the lattice is installed. These holes are for attaching bolts to fix the grill to the tray.

The disadvantage of this solution is the rapid corrosion that occurs in the pair of the fastening bolt and the thread in the hole. An example of the fight against corrosion can be the solution given in the patent of the Russian Federation for a useful model No. 148515 "Storm tray and element of the storm channel" (publ. 10.12.2014, prior 02.07.2014). The patent proposes to use a nut for fastening the bolt, installed in a hole specially created for this in the embedded element. The proposed solution allows replacing a worn-out fastening pair, but does not solve the problem of corrosion.

Another solution proposed in the design given in the patent of the Russian Federation for invention No. 2667774 "Protective grill" (publ. 09/24/2018, prior. 02/03/2015) is the use of spacer clamps, which are connected to the edge guides, to secure the protective grilles in construction. The proposed solution eliminates the need for threaded fasteners. The disadvantage of the proposed solution is that the use of the proposed solution is possible only for gratings made of light sheet material. The gratings are fastened by means of stops in the side walls of the structures, on the surface of which the grating is attached. The stop is carried out by bending the metal tape from which the clamp is made. The proposed solution is not reliable enough when used on roads with car traffic.

Closest to the claimed solution is the solution described in the RF patent for invention №2327841 (publ. 27.06.2008, prior. 04.10.2004) "Fastening device" and selected as a prototype. The patent discloses a fastening device which is designed to secure a grating fitted to the upper edge of a buried gutter body. The fastening device comprises first fastening elements provided on the lattice and second fastening elements provided on the housing located in the ground. In the fastening device, said first and second fastening elements are made with the possibility of a snap-fit connection to each other for fastening the lattice to the housing located in the ground. In this case, the first fastening elements and / or the second fastening elements each have at least one shock-absorbing section with a supporting surface forming a contact surface between the housing located in the ground and the grating. Thanks to this, the grille is held in a fixed position with an offset from the upper edge of the housing located in the ground.

Fasteners, for example, performed on the grid, according to the description, are proposed to be performed either in one piece with the grid, or to be fixed as rigidly as possible to the grid, so that the element does not lose attachment to the grid when it is removed from the gutter body.

During use, the drainage channel tray must be regularly subjected to preventive maintenance, such as cleaning, for example, of leaves or debris, for which the grill must be removed and reinstalled. These actions can lead to the separation of the fastener made on the grill. This feature is the main disadvantage of the solution described in the prototype. If, for example, a fastener located on the grill breaks off during maintenance work, the entire grill has to be replaced.

The problem solved by the invention is the creation of a stormwater inlet channel with a unit for attaching the grating to the tray, which allows simple and multiple installation and removal of the grating without damaging it.

The technical result obtained as a result of the application of the present invention is to increase the manufacturability of the structure of the storm inlet channel, which is expressed, for example, in increasing the convenience when carrying out preventive work on cleaning the storm channel, as well as maintainability.

The problem is solved and the technical result is achieved by the fact that the element of the rainwater inlet channel consists of a rainwater inlet tray and a grid installed on it. The rainwater chute has two longitudinal side walls, on each of which horizontal planes are made for installing the lattice. In this case, the longitudinal side walls of the storm-inlet chute are provided with horizontal longitudinal grooves for fixing the grating. In the horizontal planes for the installation of the lattice, there are grooves for mating with the spikes with which the lattice is equipped. Also, holes are made in the lattice along the longitudinal edges for the installation of clamps made with an elastic element.

Also, the task is solved, and the technical result is achieved by the fact that the drain channel has two opposite longitudinal side walls, on each of which there are horizontal planes for installing the lattice. In this case, horizontal longitudinal grooves are made in the longitudinal side walls of the stormwater inlet for installing the lattice retainer with an elastic element. Moreover, grooves are made in the horizontal planes for installing the grating.

Also, the task is solved, and the technical result is achieved by the fact that the lattice of the surface storm inlet channel is made of plastic and is installed on the longitudinal horizontal planes of the storm inlet. At the same time, holes are made in the lattice along the longitudinal edges for installing clamps in them. Moreover, the lattice is equipped with thorns located on the planes mating with the longitudinal horizontal planes of the rain inlet tray.

Also, the task is solved, and the technical result is achieved by the fact that the lattice of the storm inlet channel, installed on the horizontal planes of the longitudinal side walls of the chute, characterized in that it is equipped with an elastic element engaging with a horizontal longitudinal groove made in the longitudinal side walls of the chute.

Also, the task is solved, and the technical result is achieved by the fact that the latch of the storm inlet channel, installed on the horizontal planes of the longitudinal side walls of the tray, is equipped with elastic fasteners for fixing the latch in the hole made in the lattice. The latch has a projection that engages with a horizontal longitudinal groove made in the longitudinal side walls of the tray.

The presence of horizontal planes at the rainwater tray with grooves for mating with the spikes, which the grill is equipped with, allows you to quickly and easily install the grill on the tray. The execution of horizontal longitudinal grooves in the side walls of the rainwater chute allows them to be used to fix the grating installed on the chute.

The grating of the surface rain inlet channel is made of plastic, which makes it easy and convenient to install and remove from the longitudinal horizontal planes of the rain inlet channel. The presence of thorns in the lattice located on the planes mating with the longitudinal horizontal planes of the rain inlet tray allows the lattice to be accurately installed in the place of fixation. In this case, the clamps installed in the holes made along the longitudinal edges of the grating allow the grating to be fixed on the rain inlet chute. Due to the design of the invention, this is a simple and easy process.

The fact that the latch of the drainage duct grill is provided with elastic fasteners for fixing the latch in the hole made in the lattice allows replacement in case of breakage of the latch. And the fact that the latch has a protrusion that engages with a horizontal longitudinal groove made in the longitudinal side walls of the chute allows you to simply and quickly, without the use of additional equipment, install and remove the grate from the storm channel chute. Such a solution greatly simplifies, for example, preventive maintenance work on cleaning the storm inlet channel, and also increases maintainability, which is the claimed technical result, namely, increasing the manufacturability of the storm inlet channel design.

In the following, the invention is illustrated by a detailed description of a specific, but not limiting the present solution, a variant of its implementation and the accompanying drawings, in which:

- fig. 1 - assembly drawings of the grating attachment point and the drainage channel tray are presented;

- fig. 2 - drainage channel tray;

- fig. 3 - a variant of the lattice with installed clamps;

- fig. 4 - the lattice of the rainwater channel tray.

The element of the stormwater channel consists of a stormwater inlet channel 1 (Fig. 2), a grate 2 (Fig. 3) installed on the stormwater inlet channel 1 and a clamp 3 (Fig. 4) designed to fix the installed grating 2 on the stormwater inlet channel 1. Assembly drawing of the assembly the attachment of the grating 2 to the rainwater tray 1 is shown in Fig. 1.

From the assembly drawing in FIG. 1 it can be seen that a groove 4 is made on the side wall of the storm-inlet chute 1. FIG. 2 it can be seen that there are 8 such grooves on one tray 1, in the presented version there are 8 pieces, 4 grooves 4 on each side of the tray 1.

The groove 4 is designed to interact with the protrusion 5 of the latch 3. This allows you to fix the grate 2 installed on the rain inlet channel 1.

As seen in FIG. 1, the latch 3 is installed in the hole 6 of the lattice 2 and the latch 3 snaps into it thanks to the elastic fastener 7 made on the latch 3 (see also Fig. 4). In this case, the horizontal plate 11 of the latch 3 is located in the same plane with the outer surface of the lattice 2. Elastic fasteners 7 are made in the form of plates located on the body of the latch 3 on both sides, which are installed at an acute angle, so that when the latch 3 is installed in the hole 6 of the lattice 2 plates of elastic fastener 7 are squeezed by the walls of the hole 6 and after passing through the hole 6 fix the retainer 3 on the lattice 2. The proposed fastening of the retainer 3 allows its quick replacement in case of damage. To do this, it is enough to press the plates of the elastic fastener 7 and remove it from the hole 6 of the grill 2.

The rainwater chute 1 has horizontal planes 8 for mounting the grating 2. As seen in FIG. 2, the second grooves are made in the horizontal planes 8 9. In turn, on the inner surface of the grate 2 there are spikes 10, which interact with the second slots 9. When installing the grate 2 on the rainwater tray 1, the spikes 10 enter the second grooves 9. This allows you to install the grate 2 on the rain inlet channel 1 precisely, ensuring the alignment of the protrusion 5 of the retainer 3 and the groove 4 of the side wall of the storm channel 1. Also, the interaction of the spikes 10 and the second grooves 9 allows avoiding the longitudinal displacement of the grating 2 along the horizontal planes 8 of the storm channel 1 during its operation.

To install the stormwater canal system, it is necessary to place one or more stormwater trays 1 in a pre-prepared recess on the surface of the site from which the catchment will be carried out. Fix it from the outside using concrete mortar.

Then assemble the grille 2 to be installed, for which the clamps 3 should be inserted into the holes 6. Insert the clamp 3 until a click is made by the plates of the elastic fastener 7 when entering the hole 6 of the grill 2.

Install the lattice 2, equipped with spikes 10 on the horizontal planes 8 of the rainwater tray 1 so that the spikes 10 enter the second grooves 9 made in the horizontal planes 8 of the side walls of the stormwater tray 1.

Thanks to the mating tenons 10, made on the grid 2, and the second grooves 9, made on the horizontal planes of the side walls of the rain inlet chute 1, the grill 2 occupies a unique position on the chute 1. The clamps 3, already installed and fixed in the grid 2, are located in the places necessary for the protrusion 5 of the clamp 3 to fall into the groove 4 of the side wall of the rainwater tray 1.

To carry out technological operations for cleaning the stormwater channel, it is necessary to pull the edge of the grating 2, while the projections 5 come out of engagement with the grooves 4, freeing the grating 2 from fixing on the tray 1. The grating 2 is removed from the tray 1 and the stormwater channel is cleaned.

Carrying out repair work on the grille 2 is very unlikely, however, if necessary, it is possible to remove the broken retainer 3 and replace it with a new retainer 3. This operation is very simple.

The element of the rain inlet channel, made according to the invention, allows simple and repeated installation and removal of the grating 2 without damaging it, which increases the durability of the structure of the rain inlet channel. The proposed in the invention design of the element of the stormwater channel allows you to easily and simply carry out preventive work to clean the stormwater channel, as well as, if necessary, to repair the grating 2.
