Description

Technical Field

[0001] The utility model relates to the field of fire protection, in particular to an anti-collision and anti-breaking fire hydrant. Background Art

[0002] A fire hydrant is a fixed fire protection facility, and its main functions are to control combustibles, isolate combustion-supporting substances, and eliminate ignition sources. An outdoor fire hydrant is one of the important fire protection facilities for extinguishing fires. However, since it is installed outdoors, it is very easy to be accidentally damaged by various vehicles on the road. Coupled with the weak fire safety awareness of some units and individuals, the fire hydrant cannot be properly protected and maintained, resulting in its inability to play a role in fire fighting in a timely manner.

[0003] The prior art such as the Chinese patent with the publication number CN104047333A discloses a fire hydrant, which includes a hydrant body, a water outlet and a water inlet. A spherical piston for controlling the water inlet diameter is arranged inside the hydrant body between the water outlet and the water inlet. The diameter of the spherical piston is smaller than the inner diameter of the hydrant body and larger than the outer diameter of the hydrant body, and the diameter of the through hole of the spherical piston is equal to the inner diameter of the hydrant body. The fire hydrant described in the utility model can measure its own water pressure and can also increase the water pressure when the water pressure is insufficient to relieve the insufficient water pressure. However, since this fire hydrant is installed outdoors and there is no sufficient protection measure, it is easily subject to various accidental collisions. After being damaged by collisions such as vehicles, the fire hydrant is prone to cracking and bending, and the fire fighting water inside the fire hydrant will leak, which not only causes waste of resources, but also may delay the timely extinguishing of fires, resulting in more serious consequences.

[0004] In order to solve the problem that the fire hydrant is easily impacted, since the existing fire hydrants do not have sufficient anti-collision devices themselves, they are easily damaged after being impacted, or the related anti-collision devices designed are too bulky or inflexible, which may affect the normal use of the fire hydrant to a certain extent, so improvements are needed. Summary of the Invention

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose an anti-collision and anti-breaking fire hydrant.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: an anti-collision and anti-breaking fire hydrant, including a hydrant base, a hydrant body, a double-pass pipe, a single-pass pipe, a valve, and an anti-collision device. It is characterized in that: the surface of the hydrant base is fixedly connected to the hydrant body, the double-pass pipe is fixedly connected to the surface of the hydrant body, the single-pass pipe is fixedly connected to the surface of the hydrant body, the valve is rotatably connected to the surface of the hydrant body, the anti-collision device is arranged on the surface of the hydrant body, the anti-collision device includes a central column, the central column is fixedly connected to the surface of the hydrant body, and an anti-detachment block is fixedly installed on the surface of the central column.

[0007] Furthermore, positioning blocks are fixedly installed on the surface of the central column. The number of the positioning blocks is four groups. A rotating disc is rotatably connected to the surface of the central column. A positioning groove is provided by opening holes at the bottom of the rotating disc. Connecting rods are fixedly connected to the four ends of the rotating disc respectively.

[0008] Furthermore, the connecting rods are fixedly connected with vertical columns. The number of the vertical columns is four. Reflective strips are arranged on the surfaces of the vertical columns.

[0009] Furthermore, annular columns are fixedly connected to the surfaces of the vertical columns. The number of the annular columns is four groups.

[0010] Furthermore, a protection device is arranged on the surface of the valve. The protection device includes a base, and the base is fixedly connected to the surface of the central column.

[0011] Furthermore, a fixed shaft is fixedly connected inside the base. The fixed shaft is rotatably connected to the top cover, and the top cover is rotatably abutted against the surface of the valve.

[0012] Furthermore, a spring is arranged inside the base. A lock block is fixedly connected to the surface of the spring. The lock block is slidably connected to the inner wall of the base. A slider is slidably connected to the inner wall of the top cover. The lock block and the slider are inserted and connected to each other. A lock hole is opened on the surface of the base.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] 1. In the present utility model, by setting the anti-collision device, the relatively fragile double-pass pipe and single-pass pipe are protected by the vertical columns. A circle of annular columns plays a role in dispersing the impact force and strengthening the structural resistance. The reflective strips on the vertical columns play a warning role, reminding passers-by and vehicles passing by to pay attention to the position of the fire hydrant. The anti-collision device is equipped with a rotating structure. After lifting the anti-collision device and rotating it by a certain angle, the relative positions of the vertical columns and the double-pass pipe and single-pass pipe can be changed, exposing the water outlet for the user to draw water. After the water is drawn, lift the anti-collision device again, rotate it by a certain angle and then put it down, so that the positioning blocks on the rotating structure are aligned with the positioning grooves. After the two are locked, the anti-collision device will be fixed, and continue to protect the relatively fragile parts of the fire hydrant until the next use. By setting the anti-collision device, it can not only reduce the possibility of the fire hydrant being impacted when not in use, increase the anti-impact performance of the fire hydrant when it is impacted, but also conveniently move the anti-collision device to be used normally when needed. Therefore, the safety of the fire hydrant is effectively improved.

[0015] 2. In the present utility model, by providing a protection device, the originally exposed valve is protected. Only by opening the top cover outside the valve can the valve be operated. At the same time, a switch structure is provided inside the top cover. Slide the slider, causing the spring to deform under force and then contract, driving the locking block to move together. After the locking block moves, it disengages from the locking hole, and the top cover can be opened. When closing, just press hard to make the relaxed spring deform under force again, driving the locking block to move and snap into the locking hole. By providing the protection device, the valve is no longer exposed outside, reducing the possibility of being damaged externally and also avoiding the situation where the valve is blocked by external garbage. At the same time, it is ensured that the top cover has a certain stable airtightness while being manually openable and closable, and will not be easily opened or closed due to factors such as strong winds. This effectively improves the usability of the fire hydrant. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Please refer to Figures 1-5, the present utility model provides a technical solution: an anti-collision breaking fire hydrant, which includes a hydrant base 1, a hydrant body 2, a double-pass pipe 3, a single-pass pipe 4, a valve 5, and an anti-collision device 6. It is characterized in that: the surface of the hydrant base 1 is fixedly connected to the hydrant body 2, the double-pass pipe 3 is fixedly connected to the surface of the hydrant body 2, the single-pass pipe 4 is fixedly connected to the surface of the hydrant body 2, the valve 5 is rotatably connected to the surface of the hydrant body 2, and the anti-collision device 6 is arranged on the surface of the hydrant body 2.

[0024] Next, specifically describe the specific settings and functions of its anti-collision device 6 and protection device 7.

[0025] In this implementation scheme: the anti-collision device 6 includes a central column 61, the central column 61 is fixedly connected to the surface of the hydrant body 2, an anti-detachment block 62 is fixedly installed on the surface of the central column 61, a positioning block 63 is fixedly installed on the surface of the central column 61, the number of positioning blocks 63 is four groups, a rotating disk 64 is rotatably connected to the surface of the central column 61, a positioning groove 65 is provided by opening a hole at the bottom of the rotating disk 64, and connecting rods 66 are respectively fixedly connected to the four ends of the rotating disk 64.

[0026] The effects achieved by the above components are: after the positioning block 63 and the positioning groove 65 are engaged, the anti-collision device 6 can be kept fixed, making it have sufficient stability and impact resistance. After the positioning block 63 and the positioning groove 65 are disengaged, the rotating disk 64 can drive the whole anti-collision device 6 to rotate, exposing the double-pass pipe 3 and the single-pass pipe 4, and the anti-detachment block 62 is to prevent the anti-collision device 6 from detaching from the hydrant body 2 of the fire hydrant.

[0027] Specifically, the connecting rod 66 is fixedly connected to a vertical column 67, the number of vertical columns 67 is four, and reflective strips 69 are arranged on the surfaces of the vertical columns 67.

[0028] The effects achieved by the above components are: the positions of the vertical columns 67 correspond to the double-pass pipe 3 and the single-pass pipe 4 to protect them from external impacts, and the reflective strips 69 in four directions can remind passers-by and vehicles in all directions, reducing the probability of the fire hydrant being hit.

[0029] Specifically, a circular column 68 is fixedly connected to the surface of the vertical column 67, and the number of circular columns 68 is four groups.

[0030] The effects achieved by the above components are: the circular column 68 can disperse the pressure for the vertical column 67 and strengthen the impact resistance of the overall structure of the anti-collision device 6.

[0031] Specifically, a protection device 7 is arranged on the surface of the valve 5, and the protection device 7 includes a base 71, and the base 71 is fixedly connected to the surface of the central column 61.

[0032] The effects achieved by the above components are: the exposed valve 5 is protected by the base 71 to prevent it from being affected by external impacts.

[0033] Specifically, a fixed shaft 72 is fixedly connected inside the base 71. The fixed shaft 72 is rotatably connected to the top cover 73, and the top cover 73 is in rotational contact with the surface of the valve 5.

[0034] The effects achieved by the above components are as follows: The top cover 73 can rotate around the fixed shaft 72. When lifted, the valve 5 can be used normally. After being closed, the valve 5 is in a sealed state, preventing the valve 5 from being damaged or blocked by external debris.

[0035] Specifically, a spring 75 is arranged inside the base 71. A lock block 76 is fixedly connected to the surface of the spring 75. The lock block 76 is slidably connected to the inner wall of the base 71. A slider 74 is slidably connected to the inner wall of the top cover 73. The lock block 76 is inserted and connected to the surface of the slider 74. A lock hole 77 is formed on the surface of the base 71.

[0036] The effects achieved by the above components are as follows: Slide the slider 74 to cause the spring 75 to deform under force and then contract, driving the lock block 76 to move together. After the lock block 76 moves, it disengages from the lock hole 77, and the top cover 73 can thus be opened. When closing, just press firmly to make the relaxed spring 75 deform under force again, driving the lock block 76 to move and snap into the lock hole 77.

[0037] Working principle: By setting up the anti-collision device 6, the relatively fragile double-pass pipe 3 and single-pass pipe 4 are protected by the vertical column 67. The ring of columns 68 serves to disperse the impact force and enhance the structural resistance. The reflective strip 69 on the vertical column 67 serves as a warning to alert passing pedestrians and vehicles of the position of the fire hydrant. The anti-collision device 6 is equipped with a rotating structure. After lifting the anti-collision device 6 and rotating it by a certain angle, the relative positions of the vertical column 67 and the double-pass pipe 3 and single-pass pipe 4 can be changed to expose the water outlet for convenient water intake by the user. After water intake, lift the anti-collision device 6 again, rotate it by a certain angle and then lower it so that the positioning block 63 on the rotating structure aligns with the positioning groove 65. After they are locked, the anti-collision device 6 will be fixed to continue protecting the relatively fragile parts of the fire hydrant until the next use. By setting up the anti-collision device 6, it can not only reduce the possibility of the fire hydrant being hit when not in use and increase its anti-impact performance when being hit, but also conveniently move the anti-collision device 6 away for normal use when needed, effectively improving the safety of the fire hydrant. Additionally, by setting up the protection device 7, the originally exposed valve 5 is protected. Only by opening the top cover 73 outside the valve 5 can the valve 5 be operated. At the same time, a switch structure is provided inside the top cover 73. Slide the slider 74, causing the spring 75 to deform under force and contract, and move the lock block 76 along with it. After the lock block 76 moves, it disengages from the lock hole 77, and the top cover 73 can thus be opened. When closing, just press hard to make the relaxed spring 75 deform under force again, driving the lock block 76 to move and engage with the lock hole 77. By setting up the protection device 7, the valve 5 is no longer exposed, reducing the possibility of external damage and avoiding the situation where the valve 5 is blocked by external garbage. At the same time, it ensures that the top cover 73 has a certain stable airtightness while being manually openable and will not easily open or close due to factors such as strong winds, effectively improving the usability of the fire hydrant.
