[0037] Specifically, a water supply tank 2 and a high-pressure water pump 3 are provided on the mobile base 1 to provide high-pressure water flow for detection. The connecting end 41 is connected to the fire hose 42, the fire hose 42 is connected to the connector part, and the output end of the connector is connected to the return water belt 43 to form a water circulation and reduce water flow loss. The first connecting rod 51, the adjustable clamp 52 and the second connecting rod 53 constitute the fixing part 5. The adjustable clamp 52 tightens the connector part to make it relatively fixed, which is convenient for installing the fire hose 42 and the return water belt 43 and for conducting experiments.

[0038] In this way, by setting the fixing part 5 to fix the position of the fire water pump connector, the high-pressure water pump 3 is used to supply water and pressure, and the fire water pump connector is pressure tested to make the installed fire water pump connector meet the fire protection requirements.

[0039] In some feasible ways, the mobile base 1 is in the shape of a rectangular plate, the mobile wheel 11 can be selected as a universal wheel for easy movement, the water supply tank 2 is a rectangular box, the high-pressure water pump 3 is a water pump that can provide test water pressure, and can also be selected as a water pump that can adjust the pressure, such as a variable frequency water pump, so as to facilitate the testing of connectors with different pressure requirements, the fire hose 42 and the return water hose 43 are both selected as common fire hoses, so that they have good flexibility and are convenient for adapting to connectors with different interface positions. In order to facilitate the adaptation of different fire pump connector interfaces, the connection end 41 is provided with multiple output ends, each of which is connected to a fire hose 42, and the fire hose 42 is connected to different interfaces. The connection end 41 can be set as a multi-way pipe, and the fire hose 42 can be installed with different interfaces such as threaded interfaces, flange interfaces, and fire quick interfaces. A cover should be provided at the interface or a valve should be provided at the connection end 41 so that when one of them is in use, the other fire hoses 42 are closed;

[0040] The first connecting rod 51 and the second connecting rod 53 are both cylindrical rod-shaped, and the universal connection can be selected as a universal ball connection or a universal joint connection, so that the first connecting rod 51 and the second connecting rod 53 have a larger swing space, and an adjustable clamp 52 is provided at the same time, so that the fixing member 5 can adapt to a variety of connectors with different fixing positions, and the two fixing members 5 respectively fix the input end and the output end of the connector.

[0041] As a specific implementation of a fire pump coupler detection device provided in the application, the first connecting rod 51 and the second connecting rod 53 are both telescopic rods, and the first connecting rod 51 and the second connecting rod 53 are threadedly connected with a fastening bolt 511, and the fastening bolt 511 is used to fix the telescopic length.

[0042] In general, the first connecting rod 51 and the second connecting rod 53 are configured as telescopic rods, which further facilitates the adjustment of the installation angle of the adjustable clamp 52 so that it can be better adapted to different adapters.

[0043] In some feasible embodiments, the telescopic rod structure of the first connecting rod 51 and the second connecting rod 53 includes a cylindrical tube, in which a cylindrical rod is slidably inserted, and the fastening bolt 511 is threadedly connected to the side wall of the cylindrical tube and abuts against the side wall of the cylindrical rod after being tightened.

[0044] As another specific implementation of the fire pump coupling detection device provided by the application, please refer to Figure 2The adjustable clamp 52 includes a connecting block 521, which connects the first connecting rod 51 and the second connecting rod 53. The connecting block 521 has toothed belts 522 fixedly connected at both ends, and one end of one of the toothed belts 522 is fixedly connected to a quick-connect end 523.

[0045] In combination with specific usage scenarios, the quick-connect end 523 is provided to facilitate assembly and disassembly of the adjustable clamp 52 .

[0046] For some possible approaches, see Figure 3 The quick-connect end 523 includes a rectangular box 5231, in which a tooth block 5232 is slidably installed. The rectangular box 5231 is provided with a rectangular through hole. When the toothed belt 522 passes through the rectangular through hole, the tooth block 5232 engages with the toothed belt 522. Return springs 5233 are installed on both sides of the tooth block 5232. The return springs 5233 keep the tooth block 5232 and the toothed belt 522 in a meshing state. To facilitate disengagement, a pull ring is fixedly installed at one end of the tooth block 5232 away from the toothed belt 522. When loosening is required, the pull ring is pulled to disengage the tooth block 5232 from the toothed belt 522.

[0047] In other feasible embodiments, the latch tooth block 5232 can also be selected to be rotatably installed on the rectangular box 5231, and the return spring 5233 is selected to be a torsion spring. One end of the latch tooth block 5232 is provided with an engaging tooth. The return spring 5233 causes the latch tooth block 5232 to rotate to engage the toothed belt 522. The end of the latch tooth block 5232 away from the engaging tooth is a pressing end, and the latch tooth block 5232 is disengaged from the toothed belt 522 by pressing.

[0048] As a specific implementation of a fire pump coupling detection device provided in the application, please refer to Figure 1 A filter screen 21 is provided in the water supply tank 2, and the filter screen 21 separates the connection position between the high-pressure water pump 3 and the return water belt 43 into two spaces.

[0049] It should be understood that dust and residual impurities from processing during manufacturing may exist in the fire pump connector. By setting up a filter net 21, the circulating water is filtered to reduce the possibility of impurities entering the high-pressure water pump 3, thereby increasing the service life of the high-pressure water pump 3.

[0050] Furthermore, the filter screen 21 is cylindrical, and one end of the water return belt 43 is connected to the filter screen 21 along the tangent direction of the filter screen 21 .

[0051] It should be understood that by setting a cylindrical shape and allowing the return water belt 43 to enter along a tangent line when returning water, the impact of the water flow causes the water in the filter screen 21 to rotate, and the water is thrown out from the cylinder wall of the filter screen 21, and impurities are retained in the cylinder. Through rotation, the filtering efficiency is improved.

[0052] As a specific implementation of a fire pump coupler detection device provided in the application, the moving wheel 11 is connected to a driving motor.

[0053] It should be understood that in addition to the weight of the device itself, there is a large amount of water in the water supply tank 2. By providing a drive motor, it is easier to move.

[0054] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
