A plug is provided at one end of the bolt; the sealing ring is located around the plug; the water tank is installed on the outer wall of the hydrant body, and the bolt passes through the water tank. The gearbox, oil pipe, and oil hole are simple in structure and ingeniously designed, facilitating better and more even oil dispersion during lubrication. This not only provides good lubrication but also prevents rust on the threads of the lifting rod, enabling rapid opening and closing of the fire hydrant while saving time and effort.

[0004] Based on the aforementioned existing technology, the existing 90-degree long fire hydrants with base drain plugs still have the following problems: many traditional fire hydrants have manually operated drain plugs. After using the fire hydrant, the operator is very likely to forget to open the drain plug to drain the water accumulated in the cavity below the valve seat. Therefore, this utility model provides a 90-degree long fire hydrant with a base drain plug. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a 90-degree long fire hydrant with a base and drain plug, which solves the following problems that still exist in existing 90-degree long fire hydrants with base and drain plug: the drain plug of many traditional fire hydrants is a manual stopcock, and after the fire hydrant is used, the operator is very likely to forget to open the drain plug to drain the water in the cavity below the valve seat.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a 90-degree long fire hydrant with a base and drainage plug, comprising a drainage mechanism. The drainage mechanism is located on the right side of the base of the long fire hydrant to achieve adaptive drainage. The drainage mechanism includes:

It includes a drain pipe that is fixedly installed on the right side of the long fire hydrant base via a connecting component. An installation plate is fixedly installed inside the drain pipe. A sliding column is slidably installed through the installation plate. A pressure head is fixedly installed at one end of the sliding column. A drain ring is fixedly installed inside the drain pipe. The pressure head moves in conjunction with the sliding column to open and close the drain ring.

[0008] An adjustment unit is located on the right side of the adaptation unit and is used to adjust the tightness of the sliding column movement.

[0009] Preferably, a fixing plate is fixedly installed on the surface of the sliding column, and a spring is installed on the surface of the sliding column. The spring's own elastic force pushes the fixing plate and the sliding column to realize the drainage of the drainage ring.

[0010] Preferably, a rubber pad is fixedly installed on the surface of the pressure head, and the rubber pad contacts the through hole of the drain ring to increase the sealing between the pressure head and the drain ring.

[0014] This invention provides a 90-degree long fire hydrant with a base and drain plug. Compared with the prior art, it has the following advantages:

[0015] 1. This 90-degree long fire hydrant with a base and drainage plug operates by using water pressure to push a pressure head, which in turn pushes a sliding column and a fixed plate. The fixed plate compresses a spring, and the pressure head seals the drainage ring. When the fire hydrant is not in use, the internal water pressure decreases, and the spring pushes the fixed plate and sliding column back, causing the pressure head to disengage from the drainage ring. The accumulated water is then automatically discharged through the drainage hole, thus achieving automatic drainage without manual intervention.

[0016] 2. This 90-degree long fire hydrant with a base and drain plug can flexibly adjust the pressure of the pressure head on the drain ring by rotating the threaded head to compress or release the spring, adapting to different water pressure conditions and ensuring sealing stability. At the same time, the connecting component adopts a screw-on structure of threaded sleeve and connecting pipe, supporting quick disassembly and assembly of the drain pipe.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A 90-degree long fire hydrant with a base and drainage plug includes a drainage mechanism 2. The drainage mechanism 2 is located on the right side of the base of the long fire hydrant 1 to achieve adaptive drainage. The drainage mechanism 2 includes:

[0025] The adaptation unit 21 is located on the right side of the base of the long fire hydrant 1. It includes a drain pipe 211 fixedly installed on the right side of the base of the long fire hydrant 1 via a connecting component 3. An installation plate 212 is fixedly installed inside the drain pipe 211. A sliding column 213 is slidably installed through the installation plate 212. A pressure head 214 is fixedly installed at one end of the sliding column 213. A drain ring 216 is fixedly installed inside the drain pipe 211. The pressure head 214 moves in coordination with the sliding column 213 to open and close the drain ring 216.

[0026] Adjustment unit 22 is located on the right side of adaptation unit 21 and is used to adjust the tightness of the movement of sliding column 213.

[0027] In this embodiment, a fixing plate 217 is fixedly installed on the surface of the sliding column 213, and a spring 218 is installed on the surface of the sliding column 213. The spring 218 pushes the fixing plate 217 and the sliding column 213 to realize the drainage of the drainage ring 216.

[0028] The fixed plate 217 and sliding column 213 are pushed by the elastic force of spring 218, and the drain ring 216 is automatically opened when the water pressure of the fire hydrant is reduced due to the shutdown, without the need for manual operation.

[0029] In this embodiment, a rubber pad 215 is fixedly installed on the surface of the pressure head 214, and the rubber pad 215 contacts the through hole of the drain ring 216 to increase the sealing between the pressure head 214 and the drain ring 216. A number of drain holes 219 are arranged in a circumferential array on the surface of the drain pipe 211 for drainage.

[0030] Rubber pad 215 enhances the sealing between pressure head 214 and drain ring 216 to prevent leakage during operation;

[0031] The circular array of drainage holes 219 expands the drainage area, accelerates the efficiency of residual water discharge, and reduces water accumulation.

[0032] In this embodiment, the connecting component 3 includes a connecting pipe 33 fixedly installed on the right side of the base of the long fire hydrant 1. A circular groove 31 is opened on the surface of one end of the drain pipe 211. A threaded sleeve 32 is rotatably installed on one end of the drain pipe 211 through the circular groove 31. The internal convex ring of the threaded sleeve 32 is located inside the circular groove 31 and rotates. The threaded sleeve 32 is threadedly rotatably installed on the surface of the connecting pipe 33, thereby realizing the connection between the connecting pipe 33 and the drain pipe 211.

[0033] The connection / separation of the drain pipe 211 and the fire hydrant base can be completed by simply turning the threaded sleeve 32, simplifying the maintenance process;

[0034] The circular groove 31 restricts the rotation trajectory of the threaded sleeve 32, ensuring that the interface is secure and does not loosen.

[0035] In this embodiment, a sealing ring 34 is fixedly installed between the connecting pipe 33 and the drain pipe 211 to improve the sealing performance of the connection between the connecting pipe 33 and the drain pipe 211.

[0036] The sealing ring 34 fills the joint gap, preventing water from seeping out of the interface and improving the overall sealing reliability.

[0037] In this embodiment, the adjustment unit 22 includes a threaded head 221 that is rotatably installed on the right end of the drain pipe 211. The threaded head 221 has a sliding hole 222 inside, and the sliding column 213 slides inside the sliding hole 222. The spring 218 is installed between the fixed plate 217 and the threaded head 221, and the spring force of the spring 218 is adjusted by the rotation of the threaded head 221.

[0038] Rotating the threaded head 221 can compress or release the spring 218, and adjust the clamping force of the pressure head 214 on the drain ring 216 to ensure a tight seal under high pressure and timely drainage under low pressure.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] During operation, firstly, the threaded swivel 32 is screwed and rotated on the connecting pipe 33, connecting the drain pipe 211 and the connecting pipe 33. During the operation of the long fire hydrant 1, the pressure of the water flow pushes the pressure head 214, the pressure head 214 pushes the sliding column 213 and the fixed plate 217, the fixed plate 217 squeezes the spring 218, and the pressure head 214 seals the drain ring 216.

[0041] Next, when the long fire hydrant 1 is not in use, the pressure inside the long fire hydrant 1 decreases, and the spring 218 pushes the fixing plate 217 to move through its own elasticity. The fixing plate 217 drives the sliding column 213 and the pressure head 214 to move, causing the pressure head 214 to separate from the drain ring 216. The water remaining inside the long fire hydrant 1 enters the drain pipe 211 through the connecting pipe 33 and is discharged through the drain ring 216 and the drain hole 219, completing the drainage work inside the long fire hydrant 1.
