[0003] In the Chinese utility model patent with the publication number of CN217697749U, a fire pump based on the fire fighting Internet of Things is disclosed, which relates to the technical field of fire fighting pumps, including a pump body, a drain pipe is fixedly inserted on the side of the pump body, a hollow plate is fixedly inserted on the side of the drain pipe, a clamp is slidably connected to the inner wall of the hollow plate, a spring is arranged between the outer side of the clamp and the inner wall of the hollow plate, a pull rod is movably inserted on the side of the hollow plate, the pull rod passes through the hollow plate and is fixedly connected to the outer side of the clamp, a connecting pipe is movably inserted on the inner wall of the drain pipe, the side of the connecting pipe is fitted with the inner side of the clamp, and the side of the connecting pipe is fixedly sleeved with a first sealing ring. This application causes the clamp to be received in the hollow plate by the first sealing ring and the clamp conflicting with each other, and when the first sealing ring is separated from the clamp, the clamp is pushed to reset by the spring and the first sealing ring is blocked, thereby fixing the connecting pipe in the drain pipe.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: when the above-mentioned device delivers water, the staff needs to connect the connecting pipe and the drain pipe to each other. In this process, the staff needs to pull two pull rings at the same time to connect the connecting pipe and the drain pipe, which is difficult for one person to complete and the user experience is poor. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a fire pump based on the fire protection Internet of Things.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: A fire pump based on a fire-fighting Internet of Things, comprising a pump body, a drain pipe interconnected with the pump body, a connecting pipe slidably arranged in the drain pipe, and a sealing ring arranged on the connecting pipe, a connecting block is arranged on the side wall of the drain pipe, a first limiting groove is penetrated through the inner wall of the drain pipe, a second limiting groove is arranged on the side wall of the connecting block close to the drain pipe, a limiting rod is slidably arranged in the first limiting groove and the second limiting groove, an arc rod is fixed on the side wall of the limiting rod, an annular groove is arranged on the side wall of the sealing ring, a tension spring is fixed on the side wall of the limiting rod away from the drain pipe, the other end of the tension spring is fixed on the inner wall of the second limiting groove, and a driving component for driving the limiting rod is arranged on the connecting block.

[0007] By adopting the above technical solution, when the limit rod is not subjected to external force, the arc rod is pressed against the inner wall of the first limit groove under the action of the tension spring. Subsequently, when the staff needs to transport water, the staff needs to connect the connecting pipe and the drain pipe to each other, so that the connecting pipe can be initially kept stable under the joint action of the drain pipe and the sealing ring. Subsequently, when the connecting pipe moves to the maximum distance, the second limit groove is directly opposite to the annular groove. The staff only needs to start the driving assembly to move the limit rod in the direction close to the annular groove, and then the arc rod moves with the limit rod and presses against the inner wall of the annular groove, so that the connecting pipe can be kept stable under the action of the arc rod. In this process, a single person can complete the installation of the connecting pipe, which is simple to operate and provides a good user experience.

[0008] Furthermore, a movable groove is penetrated through the inner wall of the second limiting groove away from the first limiting groove, and the driving assembly includes a movable rod slidably arranged in the movable groove and a handle arranged at the end of the movable rod, and the movable rod is rotatably connected to the side wall of the limiting rod close to the tension spring.

[0009] Furthermore, an external thread is provided on the side wall of the moving rod, and an internal thread matching the external thread is provided on the inner wall of the moving groove near the handle.

[0010] By adopting the above technical solution, when the staff needs to drive the limit rod, the staff only needs to push the handle to move the limit rod toward the direction close to the annular groove. Then, when the external thread approaches the internal thread, the staff only needs to turn the handle to connect the internal thread with the external thread, thereby keeping the moving rod stable, so that the arc rod is pressed against the inner wall of the annular groove and remains stable.

[0011] Furthermore, a baffle for blocking the connecting pipe is provided on the inner wall of the drain pipe.

[0012] By adopting the above technical solution, the difficulty for workers to judge the installation position of the connecting pipe is reduced, thereby improving the use experience of the workers.

[0013] Furthermore, an anti-fool rod is fixed on the side wall of the sealing ring, and an anti-fool groove matching the anti-fool rod is opened on the inner wall of the drain pipe.

[0014] By adopting the above technical solution, the probability of the connecting pipe rotating under the action of external force during the installation process is reduced, thereby improving the stability of the connecting pipe.

[0015] Furthermore, a silicone sheet for improving the tightness of the connection of the connecting pipe is provided on the side wall of the connecting pipe.

[0016] Furthermore, a flow meter for detecting water flow velocity is arranged on the inner wall of the drain pipe.

[0017] Furthermore, a display screen is provided on the side wall of the pump body, and the display screen is electrically connected to the flow meter.

[0018] By adopting the above technical solution, due to various considerations such as economic efficiency, the staff needs to control the water flow rate during the water delivery process. When the staff turns on the pump, the flow meter detects the current water flow rate and displays it on the display screen in real time, thereby reducing the difficulty for the staff to judge the current water flow rate.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In the present application, when the limit rod is not subjected to external force, the arc rod is pressed against the inner wall of the first limit groove under the action of the tension spring. Subsequently, when the staff needs to transport water, the staff needs to connect the connecting pipe and the drain pipe to each other, so that the connecting pipe can be initially kept stable under the joint action of the drain pipe and the sealing ring. Subsequently, when the connecting pipe moves to the maximum distance, the second limit groove is directly opposite to the annular groove. The staff only needs to start the driving assembly to move the limit rod in the direction close to the annular groove, and then the arc rod moves with the limit rod and presses against the inner wall of the annular groove, so that the connecting pipe can be kept stable under the action of the arc rod. In this process, the installation of the connecting pipe can be completed by one person, which is simple to operate and provides a good user experience.

[0021] 2. In this application, when the staff needs to drive the limit rod, the staff needs to push the handle to move the limit rod toward the annular groove. Then, when the external thread approaches the internal thread, the staff only needs to turn the handle to connect the internal thread with the external thread, thereby keeping the moving rod stable, so that the arc rod is pressed against the inner wall of the annular groove and remains stable;

[0022] 3. In this application, due to economic efficiency and other considerations, the staff needs to control the water flow rate during the water delivery process. When the staff turns on the pump, the flow meter detects the current water flow rate and displays it on the display screen in real time, thereby reducing the difficulty for the staff to judge the current water flow rate.

The drain pipe 11 is a circular tubular structure, and the drain pipe 11 is connected to the pump body 1. The connecting pipe 2 is a circular tubular structure, and the connecting pipe 2 is slidably arranged in the drain pipe 11. The sealing ring 21 is arranged on the connecting pipe 2 to reduce the probability of water leakage. The connecting block 3 is a block structure, and the connecting block 3 is provided with four and distributed in sequence on the side wall of the drain pipe 11. The first limiting groove 31 is opened through the inner wall of the drain pipe 11, and the second limiting groove 4 is opened on the side wall of the connecting block 3 close to the drain pipe 11. The limiting rod 41 is a rectangular rod-shaped structure, and the limiting rod 41 is slidably arranged in the first limiting groove 31 and the second limiting groove 4. The arc rod 5 is a rod-shaped structure with an arc-shaped cross section, and the arc rod 5 is fixed on the side wall of the limiting rod 41. An annular groove 51 is provided on the side wall of the sealing ring 21, one end of the tension spring 6 is fixed on the side wall of the limiting rod 41 away from the drain pipe 11, and the other end of the tension spring 6 is fixed on the inner wall of the second limiting groove 4.

[0030] A moving groove 61 is formed on the inner wall of the second limiting groove 4 away from the first limiting groove 31. The driving assembly 7 is arranged on the connecting block 3 and is used to drive the limiting rod 41. The driving assembly 7 includes a moving rod 71 and a handle 72. The moving rod 71 is slidably arranged in the moving groove 61. An external thread 8 is arranged on the side wall of the moving rod 71, and an internal thread 81 matching the external thread 8 is arranged on the side of the inner wall of the moving groove 61 close to the handle 72. The handle 72 is arranged at the end of the moving rod 71, and the moving rod 71 is rotatably connected to the side wall of the limiting rod 41 close to the tension spring 6.

[0031] When the staff needs to drive the limit rod 41, the staff only needs to push the handle 72 to move the limit rod 41 toward the annular groove 51. Then, when the external thread 8 approaches the internal thread 81, the staff only needs to turn the handle 72 to connect the internal thread 81 with the external thread 8, thereby keeping the moving rod 71 stable, so that the arc rod 5 is pressed against the inner wall of the annular groove 51 and remains stable.
