[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] Example

[0025] like Figure 1 , Figure 2 As shown, a fire-fighting water supply device includes a connecting pipe 1, connecting pipes 2 and 3 connected to both ends of the connecting pipe 1, and a reversing connector 4 connected to the connecting pipe 2. The bottom end of the connecting pipe 3 has an interface for connecting to an underground fire hydrant. Through the combination of connecting pipes 1, 2, and 3, the underground fire hydrant can be extended to the ground, facilitating firefighters to connect hoses and avoiding the need for firefighters to descend underground to connect hoses. This reduces the risk of firefighters working in hazardous environments and improves the convenience and safety of fire-fighting operations. Simultaneously, the top end of the connecting pipe 2 is rotatably connected to the reversing connector 4. The end of the reversing connector 4 is laterally bent. This design allows the reversing connector 4 to rotate around the vertical direction, changing the orientation of the laterally bent portion. This allows for flexible adjustment of the interface direction, enabling convenient hose connection regardless of the fire truck's parking position. This effectively solves the problem of difficulty in connecting to underground fire hydrants due to limited fire truck parking space, improving the timeliness and efficiency of fire-fighting water supply.

[0026] A support frame 5 is provided on the outside of the connecting pipe 2. The support frame 5 is connected by a hinge 51 and can be disassembled and opened. After being fixed, it can form a stable structure with the connecting pipe 2. The support legs 6 on the side provide support for the connecting pipe 2, thereby providing support for the assembled pipe body. It can provide stable support for the entire water supply device, prevent it from shaking or displacing due to external forces during use, ensure the stability and reliability of the water supply process, and further guarantee the smooth operation of fire water supply.

[0027] like Figure 3As shown, the side of the connecting pipe one 1 is respectively provided with a limiting piece one 11 and a limiting piece two 12, which can be inserted with the limiting piece three 21 and the limiting piece four 31 on the connecting pipe two 2 and the connecting pipe three 3; this setting mode can effectively limit the relative rotation between the connecting pipes, and ensure that the connecting pipe one 1, the connecting pipe two 2 and the connecting pipe three 3 maintain a stable positional relationship after being connected. In the fire water supply operation, stable pipeline connection is very important. Because the water flow will generate impact force and vibration force when flowing in the pipeline, if the connecting pipes rotate, it may cause the connection to loosen, and further cause water leakage or water supply interruption and other problems, which seriously affect the smooth progress of the fire extinguishing work. Through the precise insertion design of the limiting piece, the rotation between the connecting pipes is avoided, and the structural stability and reliability of the entire fire water supply device are greatly enhanced, which provides a strong guarantee for the efficient development of the fire operation.

[0028] The cross sections of the limiting piece one 11, the limiting piece two 12, the limiting piece three 21 and the limiting piece four 31 are all square ring structures, and the square edges can provide clear directional limitation. When the limiting piece one 11 and the limiting piece three 21, and the limiting piece two 12 and the limiting piece four 31 are inserted correspondingly, the square edges are in close contact and block each other, which can more effectively prevent the relative rotation between the connecting pipe one 1, the connecting pipe two 2 and the connecting pipe three 3. For example, the limiting piece with a circular cross section may rotate when subjected to a certain torque because there is no clear angle limitation, while the square ring structure can resist this rotating trend by using its right-angle edges.

[0029] As shown in the figure, Figure 4 The arc-shaped clamping pieces of the support frame 5 can be rotated around the hinge 51 to be opened, and are locked and fixed through the locking structure at the end portion when fixed, so that a stable structure can be formed between the support frame 5 and the connecting pipes. The lock pin 7 is rotatably installed on the locking seat two 54 through a gap, and after being rotated, the lock pin 7 can be clamped in the gap of the locking seat one 53, and then the lock pin 7 is screwed and locked by the locking nut 71, so as to fix the locking seat one 53 and the locking seat two 54, so as to fix the support frame 5, so as to ensure the stable arrangement of the support leg 6 in the side mounting frame 52. The bottom of the support leg 6 is in contact with the ground by abutting against the ground, so as to provide support to the pipe body from the side, prevent the pipe body from shaking or moving due to external force during use, and ensure the stability and reliability of the water supply process.

[0030] The technical scope of the utility model is not limited to the content in the above description, and those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical thought of the utility model, and these deformations and modifications shall belong to the protection scope of the utility model.
