[0023] Refer to Figures 1 - 5 , Figure 1 which is a schematic structural diagram of a portable fire-fighting liquid suction pump in the embodiment. Figure 2 is Figure 1 an explosion structural diagram, Figure 3 is one of the explosion structural diagrams of the pump body in the embodiment, Figure 4 is the second explosion structural diagram of the pump body in the embodiment, Figure 5 is a schematic structural diagram of the cavity and the gear assembly in the embodiment. A portable fire-fighting liquid suction pump in this example includes a pump body 1 and a drive assembly 2. The pump body 11 includes a main body 11 and two sets of gear assemblies 12. The two sets of gear assemblies 12 are arranged in the main body 11 and mesh with each other. Among them, each set of gear assemblies 12 includes a gear 121 and a transmission shaft 122. The transmission shaft 122 of one of the sets of gear assemblies 12 passes out of the main body 11 from one end face of the main body 11 to the outside of the main body 11. The drive assembly 2 includes a drive shaft 21 and a drive member 22. One end of the drive shaft 21 is drivingly connected to the end of the transmission shaft 122 exposed outside the main body 11, and the driving end of the drive member 22 is drivingly connected to the other end of the drive shaft 21. In this example, the drive member 22 is a hand drill. Among them, the main body 11 also has a liquid inlet hole 1112 and a liquid outlet hole 1121 respectively. The liquid inlet hole 1112 is provided on the side wall of the main body 11 and is located on the symmetry line a-a of the two sets of gear assemblies 12. The liquid outlet hole 1121 is provided on the end face of the main body 11 facing away from the transmission shaft 122 and is far from the liquid inlet hole 1112. Both are communicated with the inside of the main body 11.

[0024] During use, the liquid inlet hole 1112 and the liquid outlet hole 1121 are respectively connected to the liquid storage cylinder and the fire truck through pipelines, and the driving member 22 is connected to the driving shaft 21. At this time, driven by the driving member 22, the driving shaft 21 drives the transmission shaft 122 to rotate, causing the gears 121 of the two driving gear assemblies 12 to rotate towards each other. As a result, the foam liquid in the liquid storage cylinder enters the pump body through the liquid inlet hole 1112 and is injected into the fire truck through the pipeline of the liquid outlet through-hole 1121, completing the injection of the fire-fighting foam liquid into the fire truck. That is, in this example, a hand drill is used as the driving member to drive the pump body 11 to work, which is convenient for carrying the pump body 11 and does not require firefighters to manually drive the pump body to work, saving time and effort.

[0025] During specific implementation, the pump body 1 can also adopt an impeller pump.

[0026] Specifically, the main body 11 includes a cavity 111 and a cover 112. One end of the cavity 111 is provided with an installation cavity 1111, and the gear assembly 12 is installed in the installation cavity 1111. The transmission shaft 122 passes through the other end of the cavity 111 and extends outside the cavity 111. The cover 112 is covered on one end of the cavity 111 and closes the installation cavity 1111. The liquid inlet hole 1112 is provided on the side wall of the cavity 111, and the liquid outlet hole 1121 penetrates through both sides of the cover 1121 and is located on the side of the cover 112 away from the liquid inlet hole 1112. In this example, the cover 112 is fixed to the main body cavity 111 of the pump body by bolts.

[0027] Furthermore, the portable fire-fighting liquid suction pump in this example further includes a connecting plate 3. The connecting plate 3 is fixed to the side wall of the cavity 111 and has a communication hole 31. The communication hole 31 is directly opposite to the liquid inlet hole 1112. The connecting plate 3 is also provided with a plurality of mounting holes 32, and the plurality of mounting holes 32 are respectively arranged around the connecting plate 3. During use, the connecting plate 3 can be installed on the fire truck through the mounting holes 32, so that the pump body 1 is fixed to the fire truck. During use, firefighters only need to connect the pipeline to the liquid inlet 1111 and the liquid outlet 1121 to use. At the same time, when the pump body 11 is working, it is not necessary to manually hold the pump body 11, which is convenient for use. In this example, the mounting plate 3 is also fixed to the side wall of the cavity 111 by bolts.

[0028] Further, one end of the transmission shaft 122 exposed outside the cavity 111 has a connector 1221. The connector 1221 is flat, with first transmission surfaces 12211 on both sides. One end of the drive shaft 21 is provided with a transmission head 211. The transmission head 211 is provided with a transmission hole 2111 corresponding to the connector 1221. The transmission hole 2111 has a second transmission surface 21111 inside. The transmission hole 2111 is sleeved outside the connector 1221, and the second transmission surface 21111 is in contact with the first transmission surface 12211. That is, in use, after the transmission head 211 of the drive shaft 21 is sleeved on the connector 1221, connecting the driving member 22 to the other end of the drive shaft 21 can drive the pump body 11 to work. When not in use, the driving member 22 and the drive shaft 21 can be disassembled respectively for storage, further improving the convenience of product use. Specifically in implementation, the drive shaft 21 can also be welded to the transmission shaft 122, and in use, only the driving member 22 needs to be connected to one end of the drive shaft 21, making the operation more convenient.

[0029] Preferably, the connecting plate 3 is further provided with a liquid inlet connector 33. One end of the liquid inlet connector 33 is installed in the communication hole 31 and communicates with the liquid inlet hole 1112. In this example, the liquid inlet connector 33 adopts a hydraulic quick connector, which is convenient for the quick disassembly and assembly of the liquid inlet pipeline, further improving the convenience of use.

[0030] Preferably, the cover body 112 further has a diversion pipe 1122. The outer shape of the diversion pipe 1122 is "L" - shaped. One end is arranged outside the liquid outlet hole 1121 and communicates with the liquid outlet hole 1121, and the other end extends in the direction away from the liquid inlet hole 1112. It can be understood that in use, the pump body 11 can be installed above the inlet of the foam liquid storage tank of the fire truck. In this way, after the fire - fighting foam liquid is pumped out from the liquid outlet 1121 of the pump body 11, under the guidance of the diversion pipe 1122 of the cover, the fire - fighting foam liquid flows downward under the action of gravity into the storage tank of the fire truck, reducing the working load of the pump body, preventing it from exceeding the torque range of the driving member 22 and causing the driving member 22 to malfunction, ensuring that the driving member 22 stably drives the pump body 11 to work, and at the same time making the pumping of the pump body 11 smoother. In this example, the cover body 112 and the diversion pipe 1122 are integrally formed of the same material.

[0031] Preferably, the other end of the diversion pipe 1122 is provided with a liquid outlet connector 11221, and the liquid outlet connector 11221 communicates with the diversion pipe 11221. In this example, the liquid outlet connector 11221 also adopts a hydraulic quick connector, which is convenient for the quick disassembly and assembly of the liquid outlet pipeline, further improving the convenience of use.

[0032] In summary, in this example, using a hand drill as the driving member to drive the pump body 11 to work not only facilitates the carrying of the pump body 11, but also when the fire truck needs to be filled with fire - fighting foam liquid, it is not necessary for firefighters to manually drive the pump body to work, saving time and effort.

[0033] The above are only embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the scope of the claims of the present utility model.
