[0001] The utility model relates to the technical field of fire hydrants, in particular to an intelligent fire hydrant with valve opening alarm. Background Technique

[0002] A fire hydrant, also known as a fire plug, is a fixed fire-fighting facility. Its main functions are to control combustibles, isolate combustion-supporting substances, and eliminate ignition sources. Fire hydrants can be classified into indoor fire hydrants and outdoor fire hydrants according to types. Therefore, the indoor and outdoor fire hydrant systems are also one of the important fire-fighting facilities for extinguishing fires.

[0003] After retrieval, the publication number is (CN221118648U), which discloses an intelligent fire hydrant with valve opening alarm, including a hydrant body. The bottom outer wall of the hydrant body is fixedly connected with a first mounting plate. A base is arranged at the bottom of the first mounting plate. The first mounting plate is fixedly connected with the base through fixing screws. A water outlet pipe is arranged on the circumferential outer wall of the hydrant body. The top outer wall of the hydrant body is fixedly connected with a third mounting plate. The top outer wall of the third mounting plate is connected with a second mounting plate through fixing screws. The top outer wall of the second mounting plate is welded with an end cover. A valve rod is arranged inside the hydrant body, and one end of the valve rod passes through the top of the end cover.

[0004] When implementing this technical solution, at least the following defects still exist: Although this utility model can achieve the effect of damage alarm, it still cannot avoid the theft of water resources, resulting in the occupation of fire hydrants, and urgent improvement is needed. Therefore, we propose an intelligent fire hydrant with valve opening alarm. Content of the Utility Model

[0015] By adopting the above technical solution, through the arrangement of the cover plate and in cooperation with the electromagnet, the position of the arc-shaped baffle can be limited, thereby protecting the interface of the fire hydrant.

[0016] Optionally, a handle is fixedly installed at the lower end of the outer side of the arc-shaped baffle, and the handles are symmetrically arranged.

[0017] By adopting the above technical solution, it is convenient to drive the arc-shaped baffle to rotate.

[0018] Compared with the prior art, the beneficial effects of the technical solution of the present application are as follows:

[0019] The technical solution of this application, through the set fire hydrant main body, cover plate, arc-shaped barrier plate, electromagnet, connecting rod, convex surface and waterproof horn, can rotate the arc-shaped barrier plate along the direction of the annular chute, and then separate the arc-shaped barrier plate from the interface on the fire hydrant, so as to facilitate the connection and use of the water pipe by firefighters. On the contrary, the interface of the fire hydrant main body can be blocked by the arc-shaped barrier plate, so as to prevent the theft of the fire hydrant. Moreover, after the arc-shaped barrier plate deforms, the contact surface between the electromagnet and the cover plate will be separated, and then the signal will be transmitted to the PLC controller, and the PLC controller will control the waterproof horn to give an alarm, so as to fully protect the fire hydrant main body and achieve the effect of alarm warning.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Please refer to Figures 1-4, the present utility model provides a technical solution: an intelligent fire hydrant with valve opening alarm, including a fire hydrant main body 1. An annular chute 11 is opened at the lower end of the fire hydrant main body 1. A valve 12 is arranged at the upper end of the fire hydrant main body 1. A cover plate 13 is welded to the upper end of the fire hydrant main body 1. Arc-shaped baffle plates 2 are arranged on both sides of the fire hydrant main body 1. An electromagnet 21 is detachably installed at the upper inner side of the arc-shaped baffle plate 2. A slider 23 is fixedly installed at the lower end of the arc-shaped baffle plate 2. A special-shaped bolt 3 movably penetrates through one side of the cover plate 13. A waterproof horn 4 is fixedly installed at the other side of the upper end of the fire hydrant main body 1. A plurality of metal sheets 32 are arranged at one side of the upper end of the fire hydrant main body 1, and the metal sheets 32 correspond to the raised surfaces 31 one by one. Through the one-to-one correspondence between the raised surfaces 31 and the metal sheets 32, a plurality of metal sheets 32 can be squeezed simultaneously. The top side of the cover plate 13 is circular, and the edge of the cover plate 13 fits with the inner side of the electromagnet 21. Through the setting of the cover plate 13, the position of the arc-shaped baffle plate 2 can be limited in cooperation with the electromagnet 21, thereby protecting the interface of the fire hydrant. A handle 22 is fixedly installed at the lower outer side of the arc-shaped baffle plate 2, and the handles 22 are symmetrically arranged, which is convenient for driving the arc-shaped baffle plate 2 to rotate.

[0027] A plurality of raised surfaces 31 are arranged at the lower end of the special-shaped bolt 3, and the raised surfaces 31 are annularly distributed. Through the setting of the raised surfaces 31, the metal sheets 32 can be squeezed.

[0028] The size of the slider 23 is adapted to the size of the annular chute 11, and the slider 23 is slidably connected to the annular chute 11. Through the cooperation of the slider 23 and the annular chute 11, the stability of the rotation of the arc-shaped baffle plate 2 can be ensured.

[0029] During use, first insert the lower end of the special-shaped bolt 3 through the cover plate 13 into the groove of the metal sheet 32. The plurality of raised surfaces 31 on the special-shaped bolt 3 simultaneously press against the metal sheet 32, thereby realizing the disconnection of the power supply. At the same time, rotate the arc-shaped baffle plate 2 along the direction of the annular chute 11, so that the arc-shaped baffle plate 2 is separated from the interface on the fire hydrant, which is convenient for firefighters to connect and use the water pipe. On the contrary, the interface of the fire hydrant main body 1 can be blocked by the arc-shaped baffle plate 2, thereby preventing the theft of the fire hydrant. When the arc-shaped baffle plate 2 is damaged and deformed, the interface of the fire hydrant main body 1 is exposed. However, when the arc-shaped baffle plate 2 is deformed, the contact surface between the electromagnet 21 and the cover plate 13 will be separated, and then the signal is transmitted to the PLC controller. The PLC controller controls the waterproof horn 4 to give an alarm, which can fully protect the fire hydrant main body 1 and can play an alarm and warning effect.
