[0013] Preferably, the method for using the movable fire pump comprises the following steps:

[0014] S1: Grab the push rod and push it forward. The push rod makes the front roller and the rear roller roll through the support base and friction force. After the user moves the device to the specified position, he steps on the pedal downward to drive the moving block to move downward. The moving block drives the brake block to extend from the bottom of the positioning table and abut against the outer wall of the rear roller to prevent the rear roller from moving.

[0016] S3: After the water flows into the heat dissipation chamber, it will push the rotating blades to rotate. The rotating blades rotate through the heat dissipation rods. The heat dissipation rods drive the fan blades to rotate. The fan blades stir the cold air to quickly rush to the pump to dissipate the heat of the pump. After pushing the rotating blades to rotate, the water will enter the input pipe. The water will eventually be sprayed out from the high-pressure nozzle through the water guide pipe to extinguish the fire point.

[0017] The present invention provides a movable fire pump and a method for using the same. Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) The movable fire pump and its use method are used by the mutual cooperation of the base assembly and the positioning assembly. The device is moved to any position and the locking and positioning of the device is completed by the push rod, thereby preventing the fire pump from being displaced due to water pressure or vibration of the pump machine during use.

[0019] (2) The movable fire pump and its use method are achieved through the coordinated use of the pump body assembly, the heat dissipation assembly and the winding assembly. Water flows through the pump casing and the water outlet pipe into the heat dissipation bin to drive the fan blades to rotate, thereby completing the heat dissipation operation of the pump, increasing the working time of the pump and avoiding pump shutdown due to high temperature.

[0020] (3) The movable fire pump and its use method are used by the cooperation of the pump body assembly, the winding assembly and the positioning assembly. After the fire extinguishing operation is completed, the water pipe can be rolled up on the outer wall of the winding rod by rotating the winding cover, and the winding reel is positioned by the plug-in block after the pedal is released, thereby avoiding the loosening and disorder of the pipeline after winding.

The left and right sides of the positioning platform (501) are fixedly connected to the outer wall of the push rod (103), and the bottom of the positioning platform (501) is fixedly connected to the top of the rear roller (502). A T-shaped through groove is provided inside the positioning platform (501), and the inner wall of the T-shaped through groove is fixedly connected to one end of the locking spring (503), and the other end of the locking spring (503) is fixedly connected to the positive end of the locking block (504). The back of the engaging block (504) is movably connected to the front of the moving block (505), the back of the moving block (505) is fixedly connected to the front of the pedal (506), and the top of the moving block (505) is fixedly connected to the bottom of the connecting plate (507), the connecting plate (507) is located on the right side of the front end and is fixedly connected to the left side of the plug-in block (509), and the plug-in block (509) is arranged inside the sliding groove (107), the bottom of the plug-in block (509) is fixedly connected to the top of the compression spring (508), and the bottom end of the compression spring (508) is fixedly connected to the inner bottom wall of the plug-in groove, and the bottom of the moving block (505) is fixedly connected to the top of the brake block (510).

7. A movable fire pump according to claim 6, characterized in that: A sliding groove is provided on the inner wall of the support plate (104) on the left side, and the inner wall of the sliding groove is slidably connected to the outer wall of the connecting plate (507).

8. A movable fire pump according to claim 6, characterized in that: The number of the rear rollers (502) is two, and the brake block (510) is arranged between the two rear rollers (502).

9. A movable fire pump according to claim 6, characterized in that: The top of the plug-in block (509) passes through the interior of the sliding groove (107) and extends to the interior of the rotating groove, and the outer wall of the plug-in block (509) located inside the rotating groove is movably plugged into the inner wall of the winding disk (401).

10. A method of using the mobile fire pump according to claim 1, characterized in that: The steps include: S1: Grab the push rod (103) and push it forward. The push rod (103) causes the front roller (102) and the rear roller (502) to roll through the support base (101) and the friction force. After the user moves the device to the designated position, he steps on the pedal (506) downward. The pedal (506) drives the moving block (505) to move downward. The moving block (505) drives the brake block (510) to extend from the bottom of the positioning platform (501) and abut against the outer wall of the rear roller (502) to prevent the rear roller (502) from moving. At the same time, the moving block (505) drives the plug-in block (509) to be pulled out of the winding reel (401) through the connecting plate (507), unlocking the winding reel (401). The water pipe (404) is separated from the outer wall of the winding rod by grabbing the high-pressure nozzle (405) and pulling the water pipe 404. S2: Connect the water inlet pipe (206) to the water source, start the pump (201), and the pump (201) drives the impeller (204) to rotate on the inner wall of the pump housing (203). The suction force generated by the impeller (204) guides the water from the water source into the water outlet pipe (205) and into the heat dissipation chamber (301); S3: After the water flows into the heat dissipation chamber (301), it pushes the rotating blades (302) to rotate. The rotating blades (302) rotate through the heat dissipation rods (303). The heat dissipation rods (303) drive the fan blades (304) to rotate. The fan blades (304) stir the cold air to quickly flow toward the pump (201) to dissipate heat from the pump (201). After pushing the rotating blades (302) to rotate, the water flows into the input pipe (403). The water flows through the water guide pipe (404) and is finally sprayed out from the high-pressure nozzle (405) to extinguish the fire point.
