Description

Technical Field

[0001] The utility model relates to the technical field of inflatable pump valves, in particular to an inflatable pump valve suspension fixing device. Background Art

[0002] In the management of spillway reservoirs, the control of discharge holes is a key link in maintaining the safe operation of the reservoir. The control of discharge holes relies on manual or simple mechanical equipment, and the discharge hole inlet is often blocked, which may not be flexible or efficient in dealing with rapidly changing water levels. In recent years, with the development of technology, inflatable pump valve suspension fixtures are often used to improve the response speed and accuracy to water level changes. Inflatable pump valves can adapt to the dynamic water level changes of the reservoir and control the water level by automatically adjusting the opening and closing of the pump valve.

[0003] However, common inflatable pump valve suspension fixing devices mostly use a group of pump valves floating on the water surface to fix the valve body. Due to the rigid fixing angle of the bracket, the pump valve is easy to shake or be impacted by the water flow, causing a large shake or even overturning, and the stability is poor. Therefore, an inflatable pump valve suspension fixing device is urgently needed to solve the technical defects mentioned in the above technology. Utility Model Content

[0004] The utility model aims to provide an inflatable pump valve suspension fixing device to solve the problem in the above background technology that the pump valve is easy to shake or shake greatly or even fall over due to the impact of water flow, and has poor stability.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an inflatable pump-valve suspension fixing device, comprising an airbag frame and an articulated seat, wherein the four corners of the airbag frame are equipped with articulated seats, and a movable frame is fixedly connected between the articulated seats on the same side, and each of the movable frames is equipped with a group of buoy frames, and each of the buoy frames is fixed with a group of inflatable buoys, and the airbag frame is fixedly connected with a plurality of groups of small airbags, the top of the airbag frame is fixedly connected with a valve seat, the top of the valve seat is fixedly connected with a pump valve, one side of the pump valve is connected with a first pipeline, and the other side of the pump valve is connected with a second pipeline.

[0006] Preferably, the valve seat is mounted on the top of the movable frame, and two groups of inflatable buoys are provided and are symmetrically distributed about the horizontal center line of the valve seat.

[0007] Preferably, the small airbags are provided in multiple groups, and the small airbags are evenly distributed in the airbag frame.

[0008] Preferably, the input end of the first pipe is a telescopic joint, a suction cup is installed at the bottom end of the first pipe, a filter plate is installed at the bottom end of the suction cup, three groups of welding blocks are welded to the edge of the bottom end of the suction cup, a group of torsion springs are fixed at each welding block, a clamping block is installed at the torsion spring, three groups of clamping slots are provided at the edge of the filter plate, and the clamping blocks are clamped and fixed to the clamping slots.

[0009] Preferably, the filter plate is installed at the bottom end of the suction cup, and the first pipe inlet is located at the center of the suction cup.

[0010] Preferably, two groups of movable frames are provided, two groups of openable hoops are welded at each group of movable frames, four corners of the valve seat are respectively assembled inside the hoops, and locking bolts are fixedly connected between the half rings of the hoops.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the inflatable pump valve suspension fixing device not only enhances the stability of the entire system, improves the automatic adjustment capability of the reservoir overflow discharge hole, prevents the pump valve and the downstream waterway from being blocked, reduces the damage to the pipeline due to water pressure changes, but also realizes the rapid disassembly of the valve seat, making maintenance more convenient;

[0012] (1) By providing an inflatable float, a small air bag, an articulated seat, and a pump valve, the double set of inflatable floats in the device can automatically float with the rise and fall of the water level, ensuring that the pump valve is always at an appropriate water level. The multiple small air bags in the middle increase the buoyancy and stability of the inflatable float. At the same time, due to the four sets of articulated seats, the inflatable float has a certain movable angle on the water surface to adapt to the changes in the water level of the reservoir. When the water level is high, the pump valve allows water to flow through the overflow area by itself, effectively reducing the risk of reservoir overflow and ensuring the safety of the downstream area. When the water level is low, the inflatable float sinks and the pump valve pumps water. The triangular structure formed by the inflatable float and the pump valve enhances the stability of the entire system, which not only improves the automatic adjustment ability of the reservoir overflow discharge hole, but also enhances the adaptability of the pump valve to environmental changes. The capacity volume of the inflatable float is calculated based on the weight of the pump valve, simplifying the design of multiple sets of small air bags;

[0013] (2) By providing a first pipe, a filter plate, an expansion joint, a welding block, a torsion spring, a clamping block, and a clamping groove, during the rainy season or flood period, a large amount of silt and floating objects may flow into the pump valve with water. The pipe connecting the pump valve to the overflow area is the first pipe, and a filter plate that is easy to disassemble is installed at the inlet. In the case of high water level self-flow, the filter plate can block impurities and large objects from entering the pump valve, preventing the pump valve and the downstream waterway from being blocked, which is crucial and conducive to maintaining the smooth flow of the reservoir discharge hole. By providing an expansion joint at the first pipe, the pipe can adapt to the pressure changes under different water levels, reducing the damage to the pipe due to water pressure changes, and has the function of protecting the pipe;

[0014] (3) By providing a valve seat, a ring hoop, and a movable frame, the valve seat and the movable frame are fixed to the movable frame by four sets of ring hoops, which can be installed and removed quickly and stably, which not only saves maintenance time but also reduces the impact on the normal operation of the reservoir during maintenance. When parts need to be replaced or deep cleaning is required, the staff can easily remove the ring hoop for maintenance, making maintenance more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Specifically, Figure 1 and Figure 3 As shown, the double-group inflatable float 1 in the device can automatically float with the rise and fall of the water level, ensuring that the pump valve 8 is always at a suitable water level. The multiple small air bags 13 in the middle increase the buoyancy and stability of the inflatable float 1. At the same time, because of the four groups of hinged seats 12, the inflatable float 1 has a certain movable angle on the water surface to adapt to the changes in the water level of the reservoir. When the water level is high, the pump valve 8 allows water to flow through the overflow area by itself, effectively reducing the risk of reservoir overflow and ensuring the safety of the downstream area. When the water level is low, the inflatable float 1 sinks and the pump valve 8 pumps water.

The pipe connecting the pump valve 8 to the overflow area is the first pipe 6, and a filter plate 5 that is easy to disassemble is installed at the inlet. In the case of high water level gravity, the filter plate 5 can block impurities and large objects from entering the pump valve 8, preventing the pump valve 8 and the downstream waterway from being blocked.

[0027] Working principle: The double-group inflatable buoy 1 in the device can automatically float with the rise and fall of the water level, ensuring that the pump valve 8 is always at the appropriate water level. The multiple small air bags 13 in the middle increase the buoyancy and stability of the inflatable buoy 1. At the same time, because of the four groups of articulated seats 12, the inflatable buoy 1 has a certain activity angle on the water surface to adapt to the changes in the water level of the reservoir. When the water level is high, the pump valve 8 allows water to flow through the overflow area by gravity, effectively reducing the risk of reservoir overflow and ensuring the safety of the downstream area.

The pipeline connecting the pump valve 8 to the overflow area is the first pipeline 6, and a filter plate 5 that is easy to disassemble is installed at the inlet. In the case of high water level gravity, the filter plate 5 can block impurities and large objects from entering the pump valve 8 to prevent the pump valve 8 and the downstream waterway from being blocked. When disassembly is required, the card block 18 is pulled hard to disengage it from the card slot 19, and the filter plate 5 can be removed and cleaned.
