Description

Technical Field

[0001] This utility model relates to the field of fire hydrant technology, and in particular to an intelligent fire hydrant. Background Technology

[0002] Intelligent fire hydrants are a new type of fire-fighting equipment that integrates multiple technologies such as sensing, communication, control, and monitoring into traditional fire hydrants. This allows for the monitoring of abnormal states such as water discharge, cover opening, and impact. They are a type of fixed fire-fighting facility, generally used to supply water to fire trucks or directly connect to hoses and nozzles for fire extinguishing. They are important fire-fighting facilities and are therefore ubiquitous in cities. However, this also means that fire hydrants in some remote areas cannot be repaired in a timely manner after being damaged or leaking due to impacts, which can easily lead to a waste of resources. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes an intelligent fire hydrant.

[0004] To achieve the above objectives, the technical solution of this utility model is to provide an intelligent fire hydrant, comprising: a valve body for connecting to a water supply pipeline, a hydrant body disposed on the valve body, a water outlet disposed on the hydrant body for connecting to a fire hose, a hydrant cover disposed on the hydrant body, an opening and closing rod disposed on the hydrant cover that can be rotated by a rotating device, a first hexagonal locking block disposed on the opening and closing rod, a valve seat disposed on the valve body, and a valve stem connected to the opening and closing rod by a lifting device. The valve seat is provided with a valve plate for sealing the valve seat under water pressure through a guiding sealing device, and a pushing device is provided between the valve stem and the valve plate.

[0005] A further improvement is that the guide sealing device includes: a positioning groove at the bottom of the valve body, a positioning ring in the positioning groove, several guide rods on the positioning ring, and a guide hole on the valve plate that cooperates with the guide rods. A sealing device is also provided between the valve plate and the valve seat.

[0006] A further improvement is that the sealing device includes: a placement groove on the valve plate with a diameter larger than that of the valve seat; a first strong magnetic block in the placement groove; a first sealing layer covering the surface of the valve plate for fixing the first strong magnetic block and enhancing the sealing performance; and a spring sleeved on the guide rod, with one end abutting against the valve plate and the other end abutting against the positioning ring.

[0007] A further improvement is that the pushing device includes: a pressure equalizing plate located at the bottom of the valve stem to increase the contact area, and a second strong magnetic block located on the pressure equalizing plate.

[0008] A further improvement is that the rotating device includes: a mounting groove on the bolt cover, a bearing in the mounting groove, and a mounting plate on the bolt cover for positioning the bearing. The opening and closing rod is fixedly connected to the bearing and extends upward through the mounting plate and downward into the bolt body.

[0009] A further improvement is that the lifting device includes: a threaded sleeve fixed on the valve stem, a connecting thread on the opening and closing rod for cooperating with the threaded sleeve, and an anti-rotation device between the threaded sleeve and the bolt body.

[0010] A further improvement is that the anti-rotation device includes: two limiting plates on the bolt body and an anti-rotation plate on the threaded sleeve with a spacing matching that of the limiting plates.

[0011] A further improvement is that the plug cover is also provided with a cap.

[0012] A further improvement is that the first hexagonal block gradually becomes thicker from top to bottom.

[0013] A further improvement is that a sealing cap is also locked onto the water outlet, and a second hexagonal locking block is also provided on the sealing cap.

[0014] The advantages and beneficial effects of this utility model are as follows: With its simple structure and convenient use, the valve plate is inverted, allowing it to seal under fluid pressure. This eliminates the need for the valve stem to be fixedly connected to the valve plate, enabling the valve plate and stem to be separated. This reduces the possibility of the valve plate and seat being compromised when the valve body is impacted and tilted, thus reducing resource waste. Attached Figure Description

In use, by turning the rotating rod with a wrench, the valve stem 8 can be moved up and down under the action of the connecting thread and the threaded sleeve 23, thereby pushing the valve plate 9 to move downward against the water pressure, releasing the seal on the valve plate 9, and at this time the fluid can flow into the plug body 2 to complete the water discharge; After use, turn the opening and closing lever 5 to move the valve stem 8 upward. At this time, the valve plate 9 will move upward along the guide rod 12 under the action of water pressure, spring 17, and the first strong magnetic block 15 and the second strong magnetic block 19 until it seals the valve plate 9. At this time, the user can continue to move the valve stem 8 upward to ensure and release the contact with the valve plate 9, so as to prevent it from affecting the seal.
