The utility model can give an alarm in time when the monitoring device is subjected to a large pressure, thereby improving the safety during detection.

[0004] The above patent has the following shortcomings: when it is used, the cylinder is installed on the fire hydrant through a threaded ring. When the water pressure of the fire hydrant is too high, the installation of the threaded ring is likely to loosen. When encountering a fire, as the fire hydrant is continuously used, once the installation of the threaded ring becomes loose, it may fall off during use, causing it to fail at the critical moment of fire extinguishing. It is not convenient to fix the fire hydrant more firmly so that it is not easy to fall off after connection. In view of this, we propose an intelligent fire hydrant water supply pressure status detector. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the prior art, the cylinder is mounted on the fire hydrant through a threaded ring.

[0024] The inventor of the utility model found that when the water pressure of the fire hydrant is too high, the installation of the threaded ring is likely to loosen, making it difficult to fix the fire hydrant more firmly so that it is not easy to fall off after connection.

[0025] like Figure 1-4As shown, an intelligent fire hydrant water supply pressure state detector comprises: a test chamber 1, a water pipe interface 2 is fixedly connected to the back of the test chamber 1, the water pipe interface 2 is used to connect the water pipe to use the water of the fire hydrant, a fire hydrant interface 3 is fixedly connected to the front of the test chamber 1, the fire hydrant interface 3 is used to dock with the water outlet of the fire hydrant, and the left and right sides of the test chamber 1 are provided with fixed components 4, the fixed components 4 include a support seat 401, the support seat 401 is fixedly connected to the test chamber 1, the front of the support seat 401 is rotatably connected to a rotating seat 402, and the specific connection method of the rotating seat 402 and the support seat 401 is that a circular block is arranged on the back of the support seat 401, the circular block is connected to the rotating seat 402 through a connecting column, the connecting column and the support seat 401 are penetrated and rotatably connected, when the rotating seat 402 is rotated, the threaded rod 403 is rotated to make the fastening plate 5 When clamping the fire hydrant, the round block will support the back of the support seat 401, playing the role of stabilizing the structure and preventing the rotating connection point between the rotating seat 402 and the support seat 401 from being damaged due to pulling. The front of the rotating seat 402 is fixedly connected to a threaded rod 403, and the front of the threaded rod 403 is fixedly connected to a knob 404. There are two groups of fixing components 4, which are symmetrically arranged on the left and right sides of the test chamber 1. A fastening plate 5 is arranged on the front of the fixing component 4, and the fastening plate 5 and the two threaded rods 403 are penetrated through threaded holes and threadedly connected. The fastening plate 5 is driven by the fixing component 4 to clamp the fire hydrant, so that the fire hydrant interface 3 and the water outlet of the fire hydrant can be firmly connected. A driving component 6 is arranged above the fixing component 4, and a detection component 8 is arranged above the test chamber 1. The water flow passing through the test chamber 1 is pressure measured by the detection component 8.

[0026] like Figure 1-4 As shown, specifically, when in use, the fire hydrant interface 3 is first connected to the water outlet of the fire hydrant. At this time, the threaded rod 403 is driven to rotate by simultaneously rotating the knobs 404 in the two sets of fixing components 4. The simultaneous rotation of the two threaded rods 403 drives the fastening plate 5 to slide backward so that it clamps the fire hydrant, so that the fire hydrant interface 3 and the water outlet of the fire hydrant are not easily loosened after being connected. The rotation of the threaded rod 403 will drive the rotating seat 402 to rotate on the supporting seat 401. When the rotating seat 402 rotates the threaded rod 403 to make the fastening plate 5 clamp the fire hydrant, the circular block connected to the rotating seat 402 through the connecting column will support the back of the supporting seat 401, thereby stabilizing the structure.

[0027] like Figure 1-4As shown, the driving component 6 includes a crown gear 601, which is fixedly connected to the outer surface of the rotating seat 402, and a bevel gear 602 is meshed on the front of the crown gear 601. A rotating column 603 is fixedly connected above the bevel gear 602. The outer surface of the rotating column 603 is rotatably connected to a support sleeve 604 through a bearing. The support sleeve 604 is fixedly connected to the support seat 401 through a connecting rod. The support sleeve 604 is used to support the rotating column 603. The number of the driving components 6 is two groups, which are respectively arranged on the two groups of fixed components 4. A lifting component 7 is arranged above the driving component 6. The lifting component 7 includes a connecting plate 701, and a screw rod 702 is threaded through the lower part of the connecting plate 701. The number of the screw rod 702 is two, which are respectively fixedly connected to the upper part of the rotating column 603 in the two groups of driving components 6. The detection component 8 includes a lifting plate 801, and a water pressure gauge 802 is arranged on the lifting plate 801. A limited position is movably penetrated above the lifting plate 801 Rod 803, the limit rod 803 is fixedly connected to the top of the test chamber 1, the lifting plate 801 is fixedly connected to the back of the connecting plate 701, and a sealing component 9 is arranged below the lifting plate 801. The sealing component 9 includes a sealing interface 901, which is fixedly connected to the top of the test chamber 1, and the sealing interface 901 is connected to the inner surface of the test chamber 1. A sealing sleeve 902 is arranged above the sealing interface 901, and a rubber sealing layer is arranged on the inner surface of the sealing sleeve 902. The sealing sleeve 902 is used to dock with the sealing interface 901 to seal the test chamber 1. The sealing sleeve 902 is fixedly connected to the bottom of the lifting plate 801, and the sealing sleeve 902 is adapted to the sealing interface 901. The lower end of the water pressure gauge 802 is arranged on the inner surface of the sealing sleeve 902. When the lifting plate 801 descends and the sealing sleeve 902 seals the sealing interface 901, the water pressure gauge 802 will extend into the test chamber 1 to measure the pressure of the water flow passing through the test chamber 1.

[0028] like Figure 1-4 As shown, specifically, when the rotating seat 402 rotates the threaded rod 403 to clamp the fastening plate 5 to the fire hydrant, the rotation of the rotating seat 402 will drive the crown gear 601 to rotate, and the rotation of the crown gear 601 will drive the bevel gear 602 to rotate the rotating column 603, and the rotation of the rotating column 603 will drive the screw 702 to rotate. At this time, the simultaneous rotation of the two screws 702 will drive the connecting plate 701 to descend, and the connecting plate 701 will drive the lifting plate 801 to descend, so that the sealing sleeve 902 is connected to the sealing interface 901, and the test chamber 1 is closed. At this time, the water pressure gauge 802 in the sealing sleeve 902 will extend into the test chamber 1 to measure the pressure of the water flow passing through the test chamber 1.

[0029] It is worth noting that the two threaded rods 403 in this embodiment need to rotate simultaneously during operation.
