Technical Field
[0001] The utility model belongs to the technical field of fire hydrants, and specifically relates to an intelligent fire hydrant anti-collision protection device. Background Art
[0002] Fire hydrants are usually installed on both sides of roads or buildings. If they are not protected, they are easily damaged by vehicles or other objects. In particular, existing smart fire hydrants are equipped with different sensors and Beidou positioning modules. Once they are damaged, the maintenance cost is high.
[0003] Installing anti-collision devices around traditional fire hydrants, such as semi-circular concrete piers or rubber fenders, can effectively prevent vehicles or other objects from directly hitting the fire hydrants. These devices can be designed in eye-catching colors to increase their visibility and further reduce the possibility of collision.
[0004] Smart fire hydrants are installed on the roadside and may be hit in a 360° range. Generally, several ring-shaped or cage-shaped steel frames are fixed on the outside as three-dimensional protection. However, the ring-shaped anti-collision structure cannot rotate, which makes it inconvenient to guide the impact object away from the smart fire hydrant and difficult to unload the impact load, which is not conducive to reducing the degree of damage caused by the impact. For this reason, we propose a smart fire hydrant anti-collision protection device. Utility Model Content
[0005] The purpose of the utility model is to provide an intelligent fire hydrant anti-collision protection device, forming an annular three-dimensional anti-collision protection device, which guides the impacting object to deflect away from the fire hydrant body after being impacted, unloads part of the impact load, and reduces the degree of damage caused by the impact.
[0006] The technical solutions adopted in this utility are as follows:
[0007] The intelligent fire hydrant anti-collision protection device comprises a fire hydrant body, wherein two coaxial inner ring slide rails are fixed at intervals on the outer side of the fire hydrant body, a plurality of support rods are distributed along a circumferential array on the outer sides of the two inner ring slide rails, an outer ring slide rail fixedly connected to the support rods is sleeved on the outer sides of the two inner ring slide rails, an outer sliding ring is slidably installed on the outer sides of the two outer ring slide rails, a plurality of nitrogen tanks are distributed along a circumferential array on the outer sides of the two outer sliding rings, the tail of the nitrogen tank has an arc that fits the outer side of the outer sliding ring and the air outlet extends tangentially along the outer sliding ring. When the fire hydrant body is installed on the roadside, the two inner ring slide rails, the plurality of support rods, the outer ring slide rail and The outer sliding ring is installed on the outside of the fire hydrant body, and several nitrogen tanks filled with nitrogen are fixed to the outside of the two outer sliding rings respectively, forming an annular three-dimensional anti-collision protection device. Once hit, the impact direction deviates from the central axis of the fire hydrant body, which can push the outer sliding ring to rotate unidirectionally around the corresponding outer ring slide rail, and the support rod, outer ring slide rail and outer sliding ring to rotate unidirectionally relative to the inner ring slide rail. If the impact direction is facing the central axis of the fire hydrant body, it will first impact and squeeze the nitrogen tank, and use the nitrogen tank to spray compressed nitrogen flow, which is pushed tangentially along the outer sliding ring to guide the impact object to deflect away from the fire hydrant body, unload part of the impact load, and reduce the degree of damage caused by the impact.
[0008] The nitrogen tank outlets are all threadedly installed with threaded plugs, which are used to seal the nitrogen tank outlets. Once impacted, the increased internal pressure will break the threaded plugs, and only the nitrogen flow will be ejected along the outlet.
[0009] The two inner ring slide rails are both slidably mounted with inner sliding rings fixedly connected to adjacent support rods, which provide support between adjacent support rods and can slide along the corresponding inner ring slide rails, thereby reducing the friction between the inner ring slide rails and the adjacent support rods.
[0010] A number of submerged steel bars are fixedly installed between the two inner ring slide rails, the lower ends of the submerged steel bars extend into the ground and the inner sides are fixedly connected to the outer side of the fire hydrant body. The submerged steel bars and one end of the fire hydrant body are pre-buried in the foundation pit and reinforced by concrete pouring, so that the submerged steel bars can be fixed.
[0011] A number of vertical rods are fixed between the sides of the two outer ring slide rails that are close to each other, and are supported inside the annular three-dimensional anti-collision protection device to enhance the anti-collision performance. The distance between two adjacent vertical rods is large enough to pass through the fire water pipe, and can also rotate around the inner ring slide rail to align the distance with the water outlet of the fire hydrant body.
[0012] The nitrogen tanks are all bonded with leather covers on the outside, and the leather covers are all curved. The elastic deformation of the leather covers is used to reduce the friction caused by the impact on the outside of the nitrogen tank, thereby avoiding the nitrogen tank from being broken due to the friction.
[0013] The technical effects achieved by this utility model are:
[0014] The practical intelligent fire hydrant anti-collision protection device has the following advantages: when the fire hydrant body is installed on the roadside, two inner ring slide rails, a plurality of support rods, an outer ring slide rail and an outer sliding ring are installed on the outside of the fire hydrant body in sequence, and a plurality of nitrogen cylinders filled with nitrogen are fixed to the outsides of the two outer sliding rings respectively, so as to form an annular three-dimensional anti-collision protection device; once impacted, the impact direction deviates from the central axis of the fire hydrant body, so as to push the outer sliding ring to rotate unidirectionally around the corresponding outer ring slide rail, and the support rod, the outer ring slide rail and the outer sliding ring to rotate unidirectionally relative to the inner ring slide rail; if the impact direction is directly opposite to the central axis of the fire hydrant body, the nitrogen cylinder is first impacted and squeezed, and the compressed nitrogen flow is sprayed from the nitrogen cylinder, which is pushed tangentially along the outer sliding ring to guide the impact object to deflect away from the fire hydrant body, thereby removing part of the impact load and reducing the degree of damage caused by the impact.

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.
[0022] like Figure 1-4As shown, the intelligent fire hydrant anti-collision protection device includes a fire hydrant body 1. The fire hydrant body 1 can select the SSFT100 / 65-1.6 ground anti-collision pressure regulating outdoor intelligent fire hydrant. Two coaxial inner ring slide rails 2 are fixed at intervals on the outside of the fire hydrant body 1. A plurality of support rods 3 are distributed along the circumferential array on the outside of the two inner ring slide rails 2. The outer sides of the two inner ring slide rails 2 are sleeved with outer ring slide rails 4 fixedly connected to the support rods 3. The outer sides of the two outer ring slide rails 4 are slidably installed with outer slip rings 5. A plurality of nitrogen tanks 6 are distributed along the circumferential array on the outside of the two outer slip rings 5. The tails of the nitrogen tanks 6 have an arc that fits the outer side of the outer slip ring 5 and the air outlets extend tangentially along the outer slip ring 5. When the fire hydrant body 1 is installed on the roadside, the two inner ring slide rails 2 are respectively The ring slide rail 2, a plurality of support rods 3, an outer ring slide rail 4 and an outer slide ring 5 are installed on the outside of the fire hydrant body 1, and a plurality of nitrogen tanks 6 filled with nitrogen are respectively fixed to the outside of the two outer slide rings 5 to form an annular three-dimensional anti-collision protection device. Once impacted, the impact direction deviates from the central axis of the fire hydrant body 1, which can push the outer slide ring 5 to rotate unidirectionally around the corresponding outer ring slide rail 4, and the support rod 3, the outer ring slide rail 4 and the outer slide ring 5 to rotate unidirectionally relative to the inner ring slide rail 2. If the impact direction is directly opposite to the central axis of the fire hydrant body 1, the nitrogen tank 6 will be impacted and squeezed first, and the compressed nitrogen flow will be sprayed by the nitrogen tank 6 to push tangentially along the outer slide ring 5 to guide the impact object to deflect away from the fire hydrant body 1, unload part of the impact load, and reduce the degree of damage caused by the impact.
[0023] Among them, the nitrogen tank 6 can be set to push to the right. If the impact object is on the left side of the central axis of the fire hydrant body 1, it will only be subject to the reverse braking action of the nitrogen tank 6 and will not be rotated. If the impact object is on the right side of the central axis of the fire hydrant body 1, it will be subject to the same direction pushing action of the nitrogen tank 6, causing deflection.
[0024] like Figure 3 and Figure 4 As shown, the nitrogen tank 6 outlet is threadedly installed with a threaded plug 7, and the threaded plug 7 is used to seal the nitrogen tank 6 outlet. Once it is hit, the increased internal pressure will break the threaded plug 7, and only the nitrogen flow will be sprayed along the outlet.
[0025] like Figure 1 and Figure 3 As shown, inner sliding rings 8 fixedly connected to adjacent support rods 3 are slidably installed on the two inner ring slide rails 2, providing support between adjacent support rods 3 and being able to slide along the corresponding inner ring slide rails 2, thereby reducing the friction between the inner ring slide rails 2 and the adjacent support rods 3.
[0026] like Figure 1 and Figure 2As shown, a number of submerged steel bars 9 are fixedly installed between the two inner ring slide rails 2, the lower ends of the submerged steel bars 9 extend into the ground and the inner sides are fixedly connected to the outer side of the fire hydrant body 1, and the submerged steel bars 9 and one end of the fire hydrant body 1 are pre-buried in the foundation pit and reinforced by concrete pouring, so that the submerged steel bars 9 can be fixed.
[0027] like Figure 1 and Figure 3 As shown, a plurality of vertical rods 10 are fixed between the sides of the two outer ring slide rails 4 that are close to each other, and the two outer ring slide rails 4 are tightened to support the inside of the annular three-dimensional anti-collision protection device to enhance the anti-collision performance. The distance between two adjacent vertical rods 10 is large enough to pass through the fire water pipe, and can also rotate around the inner ring slide rail 2 to align the distance with the water outlet of the fire hydrant body 1.
[0028] like Figure 3 and Figure 4 As shown, the outer side of the nitrogen tank 6 is bonded with a leather cover 11, and the leather cover 11 has an arc. The elastic deformation of the leather cover 11 is used to reduce the friction caused by the impact on the outside of the nitrogen tank 6 to avoid the nitrogen tank 6 from being broken due to friction.
[0029] The working principle of the utility model is as follows: when the fire hydrant body 1 is installed on the roadside, two inner ring slide rails 2, a plurality of support rods 3, an outer ring slide rail 4 and an outer slide ring 5 are installed on the outside of the fire hydrant body 1 in turn, and a plurality of nitrogen tanks 6 filled with nitrogen are fixed to the outside of the two outer slide rings 5 respectively, so as to form an annular three-dimensional anti-collision protection device. Once hit, the impact direction deviates from the central axis of the fire hydrant body 1, which can push the outer slide ring 5 to rotate unidirectionally around the corresponding outer ring slide rail 4, and the support rod 3, the outer ring slide rail 4 and the outer slide ring 5 to rotate unidirectionally relative to the inner ring slide rail 2. If the impact direction is directly opposite to the central axis of the fire hydrant body 1, the nitrogen tank 6 is first impacted and squeezed, and the compressed nitrogen flow is sprayed by the nitrogen tank 6, which is pushed tangentially along the outer slide ring 5 to guide the impact object to deflect away from the fire hydrant body 1, thereby removing part of the impact load and reducing the degree of damage caused by the impact.
[0030] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
