Description

A smart water meter water flow regulator

technical field

The invention relates to an auxiliary device for an intelligent water meter, in particular to a water flow regulator for an intelligent water meter.

Background technique

At present, smart water meters have become a common water meter for people to calculate water volume. The convenience brought by smart water meters in accurate measurement and convenient use is the main reason for gradually replacing traditional water meters. However, in some special water metering fields, such as in some relatively In the field of water consumption with small water volume calculation, the smart water meter used in this field is more refined. When the smart water meter is calculating, if the water volume is too large, the water wheel of the smart water meter will rotate too fast, which will make the rotational inertia of the water wheel too large. , which leads to inaccurate calculation of the water meter. At this time, a valve body that can adjust the water volume or other water volume regulator is needed to assist the use of the smart water meter. The traditional method is to use an electronically controlled water volume control valve to control, the control valve The preset value of excessive water volume is set. When the water volume is too large, the valve will be automatically opened and closed to ensure that the water meter is no longer connected to the water volume. After the water volume is stable, the valve body will be opened again. Accuracy, but the direct switch valve body brings a lot of trouble to the water operation, and the cost of the electronically controlled switch is high, so it cannot be popularized in a large area.

In order to solve the above deficiencies of the prior art, the present invention proposes a water flow regulator for an intelligent water meter.

In order to solve the above technical problems, the present invention adopts the following technical solutions: an intelligent water meter water flow regulator, which is characterized in that it comprises a casing, a water inlet joint is installed on the left side of the casing, and a water outlet joint is arranged on the upper side, There is a circular cavity inside the shell, an adjusting center shaft is installed at the center of the circular cavity, an adjusting disk is installed on the adjusting center shaft, and the upper part of the adjusting disk is fixed with a radially arranged adjusting disk. A pendulum rod, one end of the pendulum rod protrudes from the range of the disc surface of the adjustment plate, and a transmission link is hinged on the end of the pendulum rod, and the end of the transmission link is hingedly connected to a circular An arc-shaped elastic water flow baffle, the initial end of the elastic water flow baffle is hinged on a base block fixed on the wall of the circular cavity, and the base block is arranged at the water inlet of the water inlet joint so that the The elastic water flow baffle blocks the water inlet in the inner cavity of the casing outside the elastic water flow baffle, and the lower part of the adjustment shaft is provided with an electromagnetic drive structure that drives the adjustment shaft to rotate, and the adjustment shaft drives the swing rod by driving the swing rod. The rotation drives the transmission link to push the elastic water flow baffle forward or backward to change the size of the inner cavity of the casing that is blocked on the outside of the elastic water flow baffle, so as to adjust the water flow.

The electromagnetic drive structure is arranged in the lower shell at the lower part of the casing, and the electromagnetic drive structure includes a driven gear sleeved on the lower end of the adjusting center shaft, a cylindrical sleeve fixed on one side of the inner part of the lower shell, and a cylindrical sleeve installed on the cylindrical sleeve. The inner winding skeleton, the coil wound on the winding skeleton, the guide sleeve fixed on the side of the winding skeleton, the reciprocating push-pull rod installed through the middle hole of the guide sleeve and through the inside of the winding skeleton, A ferromagnetic core block fixed on one side of the reciprocating push-pull rod, a driving rack fixed on the other side of the reciprocating push-pull rod, and a first spring sleeved on the reciprocating push-pull rod and compressed between the guide circular sleeve and the ferromagnetic core block , the driving rack meshes with the driven gear, and the winding coil is connected to a power generating structure for supplying power to the winding coil.

Preferably, the inner end of the cylindrical sleeve is further provided with a second spring that bears against the ferromagnetic core block.

Preferably, the power generation structure includes a generator frame installed on the lower part of the water outlet joint of the casing, a generator installation bearing installed on the generator frame, a generator installed on the generator installation bearing, and a generator installed on the generator frame. The generator shaft is installed on the machine and penetrated into the water outlet joint, and the generator wheel is installed on the generator shaft and inserted into the water outlet joint.

The main point of the design of the present invention is that a structure for adjusting the water flow is arranged at the water flow position on the front side of the smart water meter. When the water flow is too large, the energization of the coil makes the two ends of the winding bobbin generate magnetic poles, which attracts the ferromagnetic core block to the winding. The skeleton moves, compresses the first spring during the movement, and pushes the driving rack to move forward. At this time, the driving rack and the driven gear work together to make the driven gear rotate, so that the adjustment shaft also rotates, and then The adjusting disc rotates, and the adjusting disc makes a fan-shaped swing with the pendulum rod, and then presses the elastic water flow baffle forward, so that the elastic water flow baffle performs an outward-expanding arc movement. When expanding outwards, the inner cavity of the outer casing on the outer side of the elastic water flow baffle block becomes smaller, so that the cavity of flowing water becomes smaller, which in turn can make the flow of water smaller, thus ensuring the accuracy of subsequent metering operations of the smart water meter. Conversely, when the amount of water is small, no adjustment is required, and at this time, the inner cavity of the housing on the outer side of the elastic water flow baffle is maximized.

In order to ensure the power supply of the winding coil, the present invention also provides a power generation structure, the power generation wheel of the power generation structure is arranged in the water outlet, the water flow drives the power generation wheel to rotate, and then drives the generator to work to complete the power generation, and the electric energy converted by the power generation structure can also be used for subsequent To use a smart water meter, you only need to connect a battery that stores electricity, and lithium batteries are the best.

In addition, it is worth mentioning that the blocking effect of the elastic water flow baffle of the present invention does not require complete sealing, as long as the size of the housing cavity outside the blocking can be changed, the above operation can be completed.

Compared with the prior art, the present invention can adjust the water output. When the water volume is too large, the elastic water flow baffle changes the size of the inner cavity of the outer casing of the partition, so that it can block the water entering from the water inlet port. Water volume, thus ensuring the measurement accuracy of the smart water meter, it does not need to use an electric valve to close the water source, it is very convenient to use, and the cost is low, and the electricity converted by the set power generation structure can not only ensure the power supply of its own winding coil, but also It can be used for smart water meters, energy saving and environmental protection, and it is worthy of extensive promotion.
