Description

An easy-to-install fire hydrant water pressure testing device Technical Field

[0001] This utility model relates to the field of fire hydrant water pressure testing, specifically an easy-to-install fire hydrant water pressure testing device. Background Technology

[0002] A fire hydrant water pressure testing device is a specialized device used to measure and monitor the water pressure of a fire hydrant system. It typically monitors the water pressure data of the fire hydrant network in real time to ensure that the system can supply water normally in emergencies. This device can help troubleshoot problems such as pipe leaks, blockages, or pump failures. During testing, the fire hydrant outlet must be closed, and the static pressure under stable conditions and the dynamic pressure after the water flow is turned on are read.

[0003] Chinese patent CN222218515U discloses a fire hydrant water pressure testing device, including a water pipe, one end of which is connected to an external fire hydrant; a sleeve, one end of which is slidably installed inside the water pipe; and a pressure gauge, located on the side wall of the sleeve, for testing the water pressure inside the fire hydrant. With the aid of an anti-impact device, the impact of water flowing out of the fire hydrant on the testing device can be reduced, preventing damage and extending its service life. A connecting pipe allows water from the pipe and sleeve to flow into a water tank, storing the water flowing from the fire hydrant for reuse by staff, saving water resources and providing convenience.

[0004] During the testing and installation process of the aforementioned patented fire hydrant water pressure testing device, the pressure generated during testing is borne solely by the water pipe of the water pressure testing device and the outlet of the fire hydrant. After the water pipe of the water pressure testing device is subjected to large pressure and repeated use, its service life will be reduced, and gaps will easily appear, allowing liquid to flow out from the water pipe of the water pressure testing device and the outlet of the fire hydrant, resulting in a decrease in the accuracy of the test. Summary of the Invention

[0005] The purpose of this utility model is to provide an easy-to-install fire hydrant water pressure testing device. It connects to the fire hydrant outlet via a connecting ring. After connection, a second connecting strip extends from the outside of the first connecting block. This extension allows the first and second connecting pieces connected to the second connecting strip to wrap around a third and second anti-slip piece. The wrapping is then rotatably embedded into the connecting hole by the first threaded rod. A limiting piece rotating outside the second threaded rod allows the second connecting strip to wrap tightly around and taut against the outside of the fire hydrant. The second connecting strip is easy to wrap, has high installation efficiency, and its support reduces the pressure required at the connecting ring position, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-install fire hydrant water pressure testing device, comprising a testing pipe with a connecting ring at one end, a sliding ring rotatably disposed on the outside of the connecting ring, a first connecting block and a second connecting block respectively disposed on both sides of the sliding ring, a receiving rod vertically disposed inside the first connecting block, a second connecting strip wound around the outside of the receiving rod, and a first connecting piece with a connecting hole, a first connecting strip and a second connecting piece with a first threaded rod sequentially disposed at the other end of the second connecting strip, the outside of the first threaded rod being threadedly engaged with the connecting hole.

[0007] Preferably, the outer part of the first threaded rod is rotatably connected to the middle position of the second connecting piece.

[0008] Preferably, a second handle is welded to one end of the first threaded rod.

[0009] Preferably, the upper end of the first connecting block is provided with a first handle, the upper end of the storage rod is welded and fixed to the lower end of the first handle through a second threaded rod, and a threaded limiting piece is provided on the outside of the second threaded rod.

[0010] Preferably, a first anti-slip plate is provided at the lower end of one side of the second connecting block, a third anti-slip plate is provided at the upper end of one side of the second connecting block, and a second anti-slip plate is provided at the upper end of the first anti-slip plate.

[0011] Preferably, the second connecting piece, the first connecting strip, the first connecting piece, the second connecting strip, and the storage rod are connected in sequence by rivets.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] When this utility model is installed at the outlet of a fire hydrant by rotating the connecting ring, the first connecting piece, the first connecting strip, and the second connecting piece are pulled out from inside the first connecting block, wrapped around the fire hydrant, and then wound between the third and second anti-slip pieces. The second connecting piece is fixed by the first threaded rod inside, which passes through and embeds into the first connecting piece. Finally, the second threaded rod rotates outside the limiting piece and fits against the upper end of the first connecting block to fix the receiving rod, so that the second connecting strip is tightened and further fixes the fire hydrant water pressure detection device. By wrapping around and fixing the fire hydrant with the second connecting strip, it can assist in bearing part of the pressure during pressure detection, reducing the pressure borne by the connecting ring. The tightening of the second connecting strip can prevent gaps between the connecting ring and the fire hydrant outlet, improving the accuracy of the detection. Furthermore, pulling out the second connecting strip from the first connecting block and wrapping it around the fire hydrant between the third and second anti-slip pieces can improve both the accuracy of the detection and the installation efficiency.

[0020] The present invention will be further described below with reference to specific embodiments.

[0021] As shown in Figure 1, an easy-to-install fire hydrant water pressure testing device according to this embodiment includes a testing pipe 1. One end of the testing pipe 1 is provided with a connecting ring 4, and the other end of the testing pipe 1 is provided with a valve 3. When the testing pipe 1 is rotated and sealed at the fire hydrant outlet position through the connecting ring 4, the liquid inside the testing pipe 1 can flow out after the valve 3 is opened. A pressure gauge 2 is provided at the upper end of the outside of the testing pipe 1. When the liquid enters the testing pipe 1 and pressure is tested, the pressure can be detected by the pressure gauge 2.

[0022] Referring to Chinese Patent No. CN222218515U, which is prior art compared to this application, the application describes pressure detection using a pressure gauge 2 and describes connection to the fire hydrant outlet via a water pipe. The connection method and pressure measurement method are existing conventional technologies, and therefore are not described in detail in this application.

[0023] To further support and connect the fire hydrant water pressure testing device, a sliding ring 5 is provided around the outside of the connecting ring 4, and the sliding ring 5 is embedded inside the connecting ring 4 and slidably connected to the inside of the connecting ring 4. A first connecting block 6 is provided on one side of the sliding ring 5, and a second connecting block 7 is provided on the other side of the sliding ring 5. The extended first connecting block 6 and second connecting block 7 can facilitate connection and facilitate bearing the force during pressure testing.

[0024] As shown in Figures 2 and 3, a storage rod 16 is vertically arranged inside the first connecting block 6, and a second connecting strap 17 is wrapped around the outside of the storage rod 16. One end of the second connecting strap 17 is connected to the outer wall of the storage rod 16 by a rivet. After being connected by the rivet, the second connecting strap 17 can be stored outside the storage rod 16 after the storage rod 16 is rotated. At the same time, when the second connecting strap 17 is wrapped around the outside of the fire hydrant, the second connecting strap 17 can be tightened by the rotation of the storage rod 16.

[0025] In addition, a first connecting piece 8 is provided at the other end of the second connecting strip 17, a first connecting strip 9 is provided at the other end of the first connecting piece 8, and a second connecting piece 10 is provided at the other end of the first connecting strip 9. When the second connecting strip 17 is wrapped around, the first connecting piece 8 and the second connecting piece 10 can be used to fix the second connecting strip 17 around the position of the second connecting block 7.

[0026] To facilitate the fixing and fitting of the first connecting piece 8 and the second connecting piece 10, a connecting hole 12 is provided through the middle position inside the first connecting piece 8, and a first threaded rod 11 is provided through the middle position inside the second connecting piece 10. The outside of the first threaded rod 11 is rotatably connected to the middle position of the second connecting piece 10, and the outside of the first threaded rod 11 is threadedly engaged with the inside of the connecting hole 12. After the second connecting piece 10 approaches the first connecting piece 8, the first threaded rod 11 can rotate in the connecting hole 12 to continuously keep the second connecting piece 10 and the first connecting piece 8 in contact.

[0027] In order to fix the first threaded rod 11, a second handle 21 is provided at one end of the first threaded rod 11, and the second handle 21 is welded to the first threaded rod 11. The welding fixation makes it easy for the user to twist the first threaded rod 11.

[0028] In addition, to facilitate the twisting of the storage rod 16, a first handle 14 is provided at the upper end of the first connecting block 6. The upper end of the storage rod 16 is welded and fixed to the lower end of the first handle 14 through the second threaded rod 13. The storage rod 16 can be rotated through the first handle 14.

[0029] In order to fix the rotating storage rod 16, a limiting piece 15 is provided on the outside of the second threaded rod 13, and the middle position of the limiting piece 15 is engaged with the external thread of the second threaded rod 13. After the limiting piece 15 is rotated, the limiting piece 15 will move toward the outer wall of the first connecting block 6. As the limiting piece 15 continues to move, it will press against the first connecting block 6, thus fixing the storage rod 16. Fixing the storage rod 16 can fix the second connecting band 17 in a taut state.

[0030] As shown in Figures 4 and 5, a first anti-slip piece 18 is provided at the lower end of one side of the second connecting block 7, and a third anti-slip piece 20 is provided at the upper end of one side of the second connecting block 7. The third anti-slip piece 20 is welded and fixed to the second connecting block 7. A second anti-slip piece 19 is provided at the upper end of the first anti-slip piece 18. The second anti-slip piece 19, the first anti-slip piece 18, and the second connecting block 7 are welded and fixed in sequence. After the second connecting strip 17 is fixed and encircled, the first connecting strip 9 is inserted between the third anti-slip piece 20 and the second anti-slip piece 19 to facilitate the fit of the first connecting piece 8 and the second connecting piece 10 and the penetration and fixation of the first threaded rod 11.

[0031] To improve the ability to withstand pressure, the second connecting piece 10, the first connecting strip 9, the first connecting piece 8, the second connecting strip 17, and the storage rod 16 are connected in sequence by rivets.

[0032] Working principle: When using the device and installing the fire hydrant water pressure testing device, rotate the testing pipe 1 to install the connecting ring 4 at the fire hydrant outlet. Rotate the sliding ring 5 to adjust the position of the first connecting block 6. Pull out the first connecting piece 8 and the second connecting piece 10 connected by the first connecting strip 9 from the first connecting block 6. After wrapping around the fire hydrant, the first connecting strip 9 spreads out between the third anti-slip piece 20 and the second anti-slip piece 19. Rotate the second handle 21 to drive the first threaded rod 11 to embed into the connecting hole 12. With the threaded engagement of the connecting hole 12 and the first threaded rod 11, the first connecting piece 8 and the second connecting piece 10 are tightly attached. Twist the first handle 14 to tighten the second connecting strip 17. Rotate the limiting piece 15 on the surface of the second threaded rod 13 so that the limiting piece 15 moves toward the first connecting block 6 and adheres to the first connecting block 6. Adhesion to the first connecting block 6 fixes the receiving rod 16 and fixes the second connecting strip 17 in a taut state. The second connecting strip 17 can bear part of the pressure borne by the connecting ring 4 by wrapping around the fire hydrant.
