[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0024] According to Figure 1 、 2 As shown in FIGS. 1, 2, and 3, a building fire - fighting water pressure detection device is proposed in this embodiment, including an instrument seat 1. A water pressure gauge 2 is provided at the upper end of the instrument seat 1. A diversion pipe 3 is provided at each of the water inlet and outlet of the instrument seat 1. A pipe joint 4 is provided at the end of the diversion pipe 3 away from the instrument seat 1. The diversion pipe 3 is connected to the pipeline interface through the pipe joint 4. When the pipeline valve is opened, the water flow in the pipeline enters the instrument seat 1 through the diversion pipe 3 and then is discharged through the other diversion pipe 3. The water pressure gauge 2 detects the water pressure of this pipe section.

[0025] A movable disk 5 is provided on each of the left and right sides of the instrument seat 1. The movable disk 5 is rotatably connected to the instrument seat 1. A reel 7 is provided on the front surface of the movable disk 5. The reel 7 is fixedly connected to the movable disk 5. An annular groove 8 is formed on the outer edge of the reel 7.

[0026] A restraint belt structure is provided in front of the reel 7. One end of the restraint belt structure is fixedly connected to the inner side of the reel 7, and the other end of the restraint belt structure bypasses the reel 7 and is detachably connected to the movable disk 5. The diversion pipe 3 can be wound up on the outer side of the reel 7. The annular groove 8 limits the reel 7. The diversion pipe 3 in the retracted state can save the occupied space of the entire detection device and also avoid the situation that the diversion pipe 3 is dragged on the ground, resulting in damage to the pipeline. The diversion pipe 3 wound around the outer side of the reel 7 can be fixed by the restraint belt structure and will not fall apart during carrying.

[0027] Regarding the restraint belt structure:

[0028] The restraint strap structure includes at least one anti - detachment strap 12. Fixed seats 13 and plug - in connectors are respectively provided at both ends of the anti - detachment strap 12. The fixed seats 13 are fixedly connected to the inner side wall of the winding drum 7, and the plug - in connectors are detachably connected to the movable disk 5.

[0029] The diversion pipe 3 is wound around the outer side of the winding drum 7. The annular groove 8 on the outer side of the winding drum 7 limits the pipe. After the plug - in connector is fixed to the movable disk 5, the anti - detachment strap 12 can restrain the diversion pipe 3.

[0030] For the specific structure of the plug - in connector, please refer to the following description.

[0031] The plug - in connector includes a positioning post 14. The positioning post 14 is inserted into a threaded hole 11 opened on the outer side of the movable disk 5. An external thread 15 is provided on the outer side wall of the positioning post 14, and the external thread 15 is thread - connected to an internal thread 16 provided on the inner side wall of the threaded hole 11. The positioning post 14 is rotatably connected to the anti - detachment strap 12. The positioning post 14 is fixed to the movable disk 5 by means of a threaded connection. When the diversion pipe 3 is removed from the winding drum 7, the positioning post 14 can be screwed out from the threaded hole 11 opened on the outer side of the movable disk 5.

[0032] To prevent the positioning post 14 from being screwed in too deeply and causing the positioning post 14 to disengage from the threaded hole 11, in a preferred solution, a retaining piece 10 is provided at the connection between the positioning post 14 and the anti - detachment strap 12. The retaining piece 10 is sleeved on the outer side of the positioning post 14 and is fixedly connected to the positioning post 14. The diameter of the retaining piece 10 is larger than the diameter of the threaded hole 11. The retaining piece 10 fixed at the connection between the positioning post 14 and the anti - detachment strap 12 can play a limiting role. After the positioning post 14 is completely screwed into the threaded hole 11, the retaining piece 10 will abut against the outer side wall of the movable disk 5, restricting the further movement of the positioning post 14.

[0033] It should be noted that the diversion pipe 3 is a corrugated pipe made of metal. The diversion pipe 3 is wavy and has flexibility, and can bend and expand within a certain range. When the diversion pipe 3 is sleeved on the outer side of the winding drum 7, it will not be bent.

[0034] Regarding the connection between the instrument seat 1 and the movable disk 5, specifically, a hinge 6 is provided between the movable disk 5 and the instrument seat 1. The movable disk 5 is pivotally connected to the instrument seat 1 through the hinge 6. The basic structure of the hinge includes two mutually connected metal plates, which are connected by one or more rotating shafts. These rotating shafts allow the two plates of the hinge to rotate relative to each other, thus realizing the opening and closing function. The advantage of using the hinge 6 is that its structure is simple and it is easy to manufacture and install.

[0035] Furthermore, the hinge 6 includes a first movable plate and a second movable plate. A rotating shaft for supporting the rotation of the first movable plate and the second movable plate is provided at the connection between the first movable plate and the second movable plate. A butterfly spring for increasing the damping at the connection is provided at the connection between the rotating shaft and the first movable plate and the second movable plate. The disc spring has good buffering and shock-absorbing capabilities and can effectively absorb impacts and vibrations during the opening and closing process of the hinge 6, reducing noise and wear. At the same time, the disc spring can also increase the damping between the two movable plates, so that the movable disc 5 will not shake randomly after receiving the two sides of the instrument base 1.

[0036] The working principle of this application:

[0037] The flow guide pipe 3 is connected to the pipeline interface through the pipe joint 4. The pipeline valve is opened, and the water flow in the pipeline enters the instrument base 1 through the flow guide pipe 3 and then is discharged through another flow guide pipe 3. The water pressure gauge 2 detects the water pressure of this pipe section.

[0038] The flow guide pipe 3 can be wound up outside the reel 7. The annular groove 8 will limit the reel 7. The flow guide pipe 3 in the retracted state can save the occupied space of the entire detection device and can also avoid the situation where the flow guide pipe 3 is dragged on the ground, resulting in damage to the pipeline.

[0039] The flow guide pipe 3 is wound around the outside of the reel 7. The annular groove 8 on the outside of the reel 7 limits the pipeline. After the plug-in part is fixed to the movable disc 5, the anti-drop belt 12 will restrain the flow guide pipe 3. The flow guide pipe 3 will not scatter during transportation.
