Description

Technical Field

[0001] This utility model relates to a water pumping device, and more particularly to an explosion-proof water pumping device. Background Technology

[0002] During emergency repairs of water blockages in gas pipelines, it's necessary to locate the lowest point of the pipeline, excavate the foundation down to the pipeline, and then cut open the gas pipeline to drain the water. However, it's difficult to find the lowest point of the underground gas pipeline and clear the blockage in one go, requiring multiple excavations, pipe cuts, drainage, and backfilling at different locations, resulting in lengthy emergency repairs and prolonged gas outages. To improve efficiency, a water pump was used to address the water blockage. During operation, external interference could cause the pump to tip over, potentially detaching the water pipe from its connection. Since the water pump carries gas, explosion-proof measures are crucial to prevent the water pipe from detaching from the pump's connection. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides an explosion-proof water pumping device, which makes it difficult for the water delivery pipe to detach from the water pump interface, thereby improving the explosion-proof performance of the water pumping device.

[0004] Technical Solution: To achieve the above objectives, this utility model provides an explosion-proof water pumping device, comprising a base, a water pump, a water pumping pipe, and a drain pipe. The water pump is mounted on the base and has an inlet and a drain port. One end of the water pumping pipe is detachably fitted onto the inlet port, and one end of the drain pipe is detachably fitted onto the drain port. The inlet and drain ports are on the same side of the water pump. The base is also provided with a clamping mechanism, which includes two movably mounted clamping members. When the two clamping members are clamped relative to each other, two clamping openings are formed between the two clamping members. One clamping opening clamps the water pumping pipe on the inlet port, and the other clamping opening clamps the drain pipe on the drain port.

[0005] Furthermore, the base is provided with a hinge seat, and the lower end of the clamping member is hinged to the hinge seat, so that the two clamping members can swing on the hinge seat to clamp each other; the base is also provided with a locking mechanism, which can lock the two clamping members into a clamped state.

[0006] Furthermore, the locking mechanism includes a bracket mounted on the base, the bracket having a pin hole and a positioning locking pin installed in the pin hole; the clamping member having a positioning hole, and when the two clamping members are clamped relative to each other, the pin hole and the two positioning holes are on the same straight line; the positioning locking pin can be inserted into the two positioning holes simultaneously to lock the two clamping members in a relative clamping state.

[0007] Furthermore, the clamping member includes a rocker arm, the lower end of which is hinged to a hinge seat. An arc-shaped clamping block is provided on the side of the rocker arm opposite to the other rocker arm, and the arc-shaped clamping blocks on the two rocker arms can cooperate to form the clamping opening.

[0008] Furthermore, the water pump is a pneumatic diaphragm pump, with the inlet and outlet ports arranged vertically on the pneumatic diaphragm pump; the upper end of the rocker arm has a bent section, and the positioning hole is correspondingly opened on the bent section; when the two rockers are rocked to a vertical state on the hinge, the bent sections on the two rockers are staggered vertically, and the positioning holes on both rockers are located directly below the pin hole.

[0009] Furthermore, the bracket is provided with a handle, which is located directly above the water inlet and the drain outlet, and the pin hole is correspondingly opened on the handle.

[0010] Furthermore, the arc-shaped clamp has a certain degree of elasticity, and when the arc-shaped clamp is clamped on the water pump or drain pipe, it can deform to fit tightly against the pipe body.

[0011] Furthermore, the arc-shaped clamping blocks are adjustablely mounted on the rocker arm; when the two clamping members are clamped relative to each other, the distance between the two opposing arc-shaped clamping blocks is adjustable.

[0012] Beneficial effects: The explosion-proof water pumping device of this utility model has two rocker arms on the base where the water pump is located. The rocker arms have arc-shaped clamps. As the rocker arms are rocked, the arc-shaped clamps on the two rocker arms can cooperate to form two clamping ports, which respectively clamp the water pumping pipe on the water inlet and the drain pipe on the water outlet, making it difficult for the water pumping pipe and the drain pipe to fall off the water pump interface, thereby improving the explosion-proof performance of the water pumping device.

[0014] Appendix Figure 2 This is a schematic diagram showing the two clamping components when they are separated. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] As attached Figures 1 to 2The explosion-proof water pumping device includes a base 1, a water pump 2, a pumping pipe, and a drain pipe. The water pump 2 is mounted on the base 1 and has an inlet port 3 and a drain port 4. One end of the pumping pipe is detachably fitted onto the inlet port 3, and one end of the drain pipe is detachably fitted onto the drain port 4. When using the water pump 2 to repair a water blockage in a gas pipeline, the pumping pipe is inserted into the gas pipeline from the riser cover plate, and the water pump 2 is started to pump water. This allows for rapid repair of the gas pipeline water blockage, avoiding time-consuming and labor-intensive procedures such as excavating the foundation, finding the lowest point of the gas pipeline, cutting the pipe for drainage, welding, and restoring the foundation, thus greatly saving labor costs.

[0017] During the operation of water pump 2, external interference may cause it to tip over, resulting in the water delivery pipe detaching from its interface. Since the water pumped by water pump 2 contains flammable gas, explosion-proof requirements are very high, and it is necessary to prevent the water delivery pipe from detaching from the interface of water pump 2. Therefore, the pumping device needs to be optimized.

[0018] On the water pump 2, the inlet port 3 and the outlet port 4 are located on the same side of the pump 2. A clamping mechanism is also provided on the base 1. The clamping mechanism includes two movably arranged clamping members. When the two clamping members are clamped together, two clamping openings 5 ​​are formed between them. One clamping opening 5 can clamp the water pipe fitted onto the inlet port 3, and the other clamping opening 5 can clamp the outlet pipe fitted onto the outlet port 4. Because the water pipe and outlet pipe are clamped to the interfaces, even if the pumping device accidentally tilts, the water pipe and outlet pipe are not easily detached from the interfaces, thereby improving the explosion-proof performance of the pumping device.

[0019] Specifically, a hinge seat 6 is provided on the base 1, and the lower ends of the clamping members are hinged to the hinge seat 6. The two clamping members can be rocked on the hinge seat 6 to clamp each other, thereby clamping the water pipe and the drain pipe. The two clamping members can also be rocked on the hinge seat 6 to separate, so that the water pipe and the drain pipe can be easily fitted onto the interface of the water pump 2. A locking mechanism is also provided on the base 1, which can lock the two clamping members in a relatively clamped state to maintain the clamping of the water pipe and the drain pipe.

[0020] As attached Figure 1 and 2As shown, the locking mechanism includes a bracket 7 mounted on the base 1, with a pin hole 8 on the bracket 7, and a positioning locking pin 9 installed in the pin hole 8. Positioning holes 10 are provided on the clamping members. When the two clamping members are clamped together, the pin hole 8 and the two positioning holes 10 are aligned. The positioning locking pin 9 can be simultaneously inserted into both positioning holes 10, locking the two clamping members in a clamped state. Removing the positioning locking pin 9 from the two positioning holes 10 releases the locking of the clamping members. Due to the use of the positioning locking pin 9 and positioning holes 10, operation is more convenient. (See attached diagram) Figure 2 As shown, the positioning locking pin 9 is T-shaped, which prevents the positioning locking pin 9 from falling out of the pin hole 8.

[0021] The clamping component includes a rocker arm 11, the lower end of which is hinged to a hinge seat 6. An arc-shaped clamping block 12 is provided on the side of the rocker arm 11 opposite to the other rocker arm 11. Each rocker arm 11 has two arc-shaped clamping blocks 12. The arc-shaped clamping blocks 12 on the two rocker arms 11 can cooperate to form two clamping openings 5, which are used to clamp the water inlet pipe fitted on the water inlet 3 and the drain pipe fitted on the drain outlet 4, respectively.

[0022] The arc-shaped clamp 12 has a certain degree of elasticity. When the arc-shaped clamp 12 is clamped on the water pipe or the drain pipe, it can deform to fit tightly against the pipe body to ensure that the water pipe and the drain pipe are clamped tightly. The inner side of the arc-shaped clamp 12 is also provided with tooth-like patterns, which can increase the pressure and make the arc-shaped clamp 12 bite tightly onto the water pipe and the drain pipe.

[0023] The arc-shaped clamping block 12 is adjustablely mounted on the rocker arm 11. When the two clamping members are clamped together, the distance between the two opposing arc-shaped clamping blocks 12 is adjustable. In one embodiment, a screw is connected to the arc-shaped clamping block 12, and the screw is threadedly connected to a screw hole in the rocker arm 11. Rotating the screw adjusts the position of the arc-shaped clamping block 12. The arc-shaped clamping block 12 is rotatably connected to the screw, and after rotating the screw, the angle of the arc-shaped clamping block 12 can be adjusted to correspond to the drain pipe or the pumping pipe.

[0024] The water pump 2 is a pneumatic diaphragm pump. In the transportation of flammable and explosive substances, the pneumatic diaphragm pump does not generate sparks and produces no heat during operation, preventing overheating of the machine and fluid, thus ensuring high safety and reliability. The water inlet 3 and drain 4 are vertically arranged on the pneumatic diaphragm pump. The upper end of the rocker arm 11 has a bent section 13, and the positioning hole 10 is correspondingly located on the bent section 13. When the two rocker arms 11 are rocked to a vertical position on the hinge seat 6, the bent sections 13 on the two rocker arms 11 are staggered vertically, and the positioning holes 10 on both rocker arms 11 are located directly below the pin hole 8.

[0025] The bracket 7 is equipped with a handle 14, which is located directly above the water inlet 3 and the drain 4. The pin hole 8 is correspondingly opened on the handle 14. The base 1 can be lifted by the handle 14, making it convenient to carry the entire water pumping device.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
