Description

Technical Field

[0001] This utility model relates to the field of water conservancy equipment technology, specifically a pump station safety detection device. Background Technology

[0002] A pumping station is a device and engineering project that provides hydraulic and pneumatic power with a certain pressure and flow rate. The term "pump and pumping station engineering" refers to the collective structure of an irrigation and drainage pumping station, including its inlet, outlet, and pump house. After construction, a safety inspection is required to ensure safe operation of the pumping station.

[0003] During the operation of a pumping station, the pipe connections are crucial for ensuring the system's proper functioning; however, these connections are also frequent sites of leakage. Minor leaks, in particular, are difficult to detect promptly due to slow and inconspicuous water flow. Relying on manual, continuous monitoring of these potential leaks would not only significantly increase the workload of staff but also potentially cause additional physical and mental strain due to prolonged, intensive observation. Furthermore, the efficiency and accuracy of manual monitoring are limited. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 As shown, a pump station safety detection device includes a connecting shell 1, side blocks 2 fixed on both sides of the surface of the connecting shell 1, a collecting shell 3 fixed on the surface of the connecting shell 1, a conical cover 4 provided in the inner cavity of the collecting shell 3, a limit bracket 5 fixed on the surface of the conical cover 4, an alarm mechanism 6 for water leakage alarm provided on the surface of the limit bracket 5, and a clamping mechanism 9 provided in the inner cavity of the connecting shell 1 for clamping the device on the surface of the pump station pipeline.

[0020] The alarm mechanism 6 includes a suspension block 61 movably disposed within the inner cavity of the conical cover 4 and a receiver head 64 fixed to the surface of the conical cover 4. A connecting rod 62 is fixed to the surface of the suspension block 61, and a sensor head 63 is fixed to the other end of the connecting rod 62. The sensor head 63 and the receiver head 64 are electrically sensed after contact. In this embodiment, through the arrangement of the suspension block 61, the connecting rod 62, the sensor head 63 and the receiver head 64, after the suspension block 61 is subjected to the buoyancy of water, the sensor head 63 and the receiver head 64 can be brought into contact under the action of the connecting rod 62, and then a water leakage alarm is triggered by the electrical induction of the sensor head 63 and the receiver head 64.

[0021] A protective cover 8 is fixed to the surface of the limiting bracket 5, and the sensing head 63 slides in the inner cavity of the protective cover 8. In this embodiment, the protective cover 8 provides protection for the use between the sensing head 63 and the receiving head 64, and prevents water droplets from falling on the surface of the sensing head 63 and affecting the normal use of the sensing head 63.

[0022] A guide block 7 is fixed to the surface of the receiving head 64. The surface of the guide block 7 is rounded, and both sides of the guide block 7 are fixed to the inner cavity of the collecting shell 3. In this embodiment, the guide block 7 is used to guide the falling water so that the water falls into the conical cover 4 better, so that the suspension block 61 can work.

[0023] The clamping mechanism 9 includes a motor 91 fixed to the inner cavity of the connecting shell 1. The output shaft of the motor 91 is equipped with a first transmission rod 92 via bevel gear transmission. Both sides of the surface of the first transmission rod 92 are equipped with second transmission rods 93 via bevel gear transmission. The other end of the second transmission rod 93 is equipped with a bidirectional threaded rod 94 via bevel gear transmission. Both sides of the surface of the bidirectional threaded rod 94 are engaged with clamping blocks 95. In this embodiment, through the arrangement of the motor 91, the first transmission rod 92, the second transmission rod 93, the bidirectional threaded rod 94 and the clamping blocks 95, when the motor 91 is working, the first transmission rod 92 can be rotated, which in turn causes the second transmission rod 93 to drive the bidirectional threaded rod 94 to rotate, thereby causing the bidirectional threaded rod 94 and the clamping blocks 95 to engage. Under the action of the clamping blocks 95 on both sides, the pipe can be clamped, allowing the device to be placed on the surface of the pipe.

[0024] A limiting rod 10 is slidably provided on one side of the surface of the clamping block 95. Both sides of the limiting rod 10 are fixed to the surface of the side block 2. Both sides of the surface of the first transmission rod 92 are rotatably provided with bearing seats 11. The other end of the bearing seats 11 is fixed to the inner cavity of the connecting shell 1. In this embodiment, the setting of the limiting rod 10 and the bearing seats 11 provides a limit for the operation of the clamping block 95, improves the stability of the clamping block 95 during operation, and improves the stability of the first transmission rod 92 during rotation under the action of the bearing seats 11.

[0025] Working Principle: During safety inspections of the pump station, operators can use the clamping mechanism 9. Under the action of the motor 91, the first transmission rod 92 drives the second transmission rod 93 to rotate. The second transmission rod 93 then causes the bidirectional threaded rod 94 to move the two clamping blocks 95 in opposite directions, facilitating the clamping of the pipeline by the two clamping blocks 95. Once the distance between the two clamping blocks 95 is sufficient to clamp the pipeline, the operators can place the two clamping blocks 95 on the surface of the pipeline. Then, the motor 91 is used again, causing the two clamping blocks 95 to clamp the pipeline... The clamping mechanism positions the collecting shell 3 and the conical cover 4 below the pipe connection. During the safety detection phase, if a leak occurs at the pipe connection, the water can be concentrated near the suspended block 61 through the conical cover 4. If the water volume increases, the connecting rod 62 can move the sensor head 63 under the action of buoyancy, causing the sensor head 63 and the receiver head 64 to come into contact. Under the action of the sensor head 63 and the receiver head 64, an electrical signal is sent to the outside world. After processing by the system, a leak alarm is triggered, achieving the purpose of safety protection. The working principle of the sensor head 63 and the receiver head 64 is existing technology and will not be described in detail here.
