TECHNICAL FIELD

[0001] The utility model relates to fire hose detection technical field, concretely is a fire hose leak detection device for fire detection. BACKGROUND

[0002] Fire hose is a kind of hose for transporting high-pressure water or foam such as fire-retardant liquid, mainly used in fire-fighting system, help to extinguish fire, and then need to carry out fire hose leak detection on fire hose periodically.

[0003] For example, the fire hose leak detection device for fire detection with the authorization announcement number "CN221867245U" can be easily moved to the position where fire detection is needed, and the installation and disassembly are simple, the operation of installing fire hose and fire nozzle is the same, the practicability of the device is improved, and the space occupied when not in use is small, which is in line with the actual application scene. But the fire hose leak detection device for fire detection, because the pressure display is exposed for a long time, a lot of dust will accumulate on it, and the dust on the pressure display is cleaned every time, thereby reducing the practicability. UTILITY MODEL CONTENT

[0004] The utility model aims at solving the problem that the practicability is reduced because the pressure display is exposed for a long time, a lot of dust will accumulate on it, and the dust on the pressure display is cleaned every time, and provides a fire hose leak detection device for fire detection.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] A fire hose leak detection device for fire detection is designed, which comprises a first pipe body and a fire hose, the right end of the first pipe body is connected with the fire hose through a flange, the right end of the fire hose is connected with a second pipe body through a flange, the upper end of the first pipe body is provided with a pressure display, and the upper end of the pressure display is provided with a protection mechanism.

[0007] Preferably, the inner walls of the first pipe body and the second pipe body are provided with valves.

[0008] Preferably, the protection mechanism comprises a shell, the inner wall of the shell is fixedly connected with the pressure display, the inner wall of the shell is slidably connected with a baffle, the left inner wall of the baffle is clamped with a bent plate, the outer wall of the bent plate is slidably connected with the shell, and the inner walls of the two sides of the bent plate are slidably connected with a rod body.

[0009] Preferably, the two ends of the rod body are fixedly connected with the shell, the outer wall of the rod body is provided with a spring, and the two ends of the spring are fixedly connected with the bent plate and the shell respectively.

[0010] Preferably, the lower end of the bent plate is fixedly connected to the tie rod, and the outer wall of the tie rod is slidably connected to the housing.

[0011] This utility model proposes a fire hose leakage detection device, the advantages of which are as follows: Through the cooperation of the protective mechanism and the pressure display, pulling down the lever causes the bent plate to move downwards, at which point the spring is stretched. After the bent plate separates from the baffle, the lever is stopped. Then, the baffle is moved to the left. When the groove on the right side of the baffle aligns with the upper end of the bent plate, the lever is released. The spring rebounds, causing the bent plate to move upwards and engage with the groove on the right side of the baffle, thus limiting the position of the baffle. In this way, the baffle is moved away from above the pressure display. This allows observation of the data within the pressure display. After detecting a leak in the fire hose, pull down the lever to release the limit on the baffle, then move the baffle to the right. The groove on the left side of the baffle aligns with the curved plate. Release the lever to move the curved plate upward and engage it with the groove on the left side of the baffle. In this way, the baffle can be removed from the pressure detector during use. When not in use, the baffle can block the pressure display, preventing external dust from accumulating on it. This eliminates the need for frequent cleaning of the pressure display, thus increasing its practicality. Attached Figure Description
