Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1 to 4, in embodiment 1 of the present invention, an anti-collision fire hydrant includes a fire hydrant body 1, an underground water pipe 9, a flexible tube 7, a buffer device 5, a foam rubber ring 16, and a standby water outlet device 12; the fire hydrant body 1 comprises a cover plate 2, a main water pipe connector 3 and an auxiliary water pipe connector 4; the buffer device 5 is of a U-shaped cavity structure, a plurality of groups of buffer springs 6 are fixedly connected in the cavity, and a plurality of groups of limit needles 15 and flexible backing plates 18 are fixedly connected at the bottom of the buffer device 5; the bottom of the fire hydrant body 1 and the bottom of the buffer device 5 are sequentially arranged on a boss 14 at the top end of the underground water pipe 9 and are in positioning connection through a threaded hole 8; the foam rubber ring 16 is positioned on the inner side of the bottom of the buffer device 5; the side surface of the underground water pipe 9 is connected with a standby water outlet device 12, and the standby water outlet device 12 comprises a standby water pipe 13, a waterproof gasket 11 and a water pipe cover 10.

When receiving the striking, slight striking can receive buffer spring 6 buffering of buffer 5 earlier, and buffer spring 6 can't accomplish the impact force of release through flexible section of thick bamboo 7 secondary buffering, still can't release just can strike fire hydrant body 1, and fire hydrant body 1 intensity is very high, can not be impaired easily, and the loss that slight striking caused, staff can restore through changing buffer 5 and flexible section of thick bamboo 7.

The flexible tube 7 is wrapped outside the fire hydrant body 1. The bottom of the buffer device 5 is fixedly connected with a plurality of groups of limiting needles 15 and flexible backing plates 18, the tail parts of the limiting needles 15 are fixedly connected with the outer wall of the buffer device 5, and the needle heads point to the inside. And the flexible base plate 18 is provided with a threaded hole 8 corresponding to the position and the size of the fire hydrant body 1. The outer layer of the foam rubber ring 16 is wrapped with a flexible waterproof layer 17.

When receiving violent striking, buffer 5 and flexible layer can only release the fractional impact force, huge impact force still can lead to the fire hydrant to damage the deformation, buffer 5 one step earlier damage deformation this moment, the spacing needle 15 of deformation back bottom receives the drive, to the inside removal of fire hydrant, the needle point punctures the flexible waterproof layer 17 of foam rubber ring 16 outer floor, foam rubber ring 16 and air and water contact, the export of filling up underground water pipe 9 is enlargied in the rapid expansion, and solidify rapidly, stifled underground water pipe 9 of dying, avoid underground water pipe 9 to lose the restriction, violent water spray, cause the waste of water resource and the inconvenience of pedestrian's trip.

Example 2

Referring to fig. 1 to 4, the main differences between the embodiment 2 and the embodiment 1 are:

the standby water outlet device 12 is located underground, and the upper surface of the water pipe cover 10 is flush with the ground. The water pipe cover 10 is connected with the standby water pipe 13 through threads, and a waterproof gasket 11 is clamped between the water pipe cover 10 and the standby water pipe 13.

When daily not putting into use, reserve water installation 12 upper surface flushes with ground, does not influence the road and uses, does not also cause the space to be extravagant, when fire hydrant body 1 is crashed, if meet with the conflagration and need the fire hydrant water supply, can rotate to open water pipe cover 10, with the reserve water pipe 13 of water piping connection reserve water system, can normally supply water and put out a fire, avoid because fire hydrant body 1 damages unable water supply, the bigger loss of property that causes.

The utility model discloses a theory of operation is:

the installation and fixation of the device and the connection mode of all components are the known technology in the industry and are not described in detail. After the installation, 1 outside rigid couplings of fire hydrant body have flexible section of thick bamboo 7 and buffer 5, and double buffering is received buffer spring 6 and flexible section of thick bamboo 7 deformation when light collision, the release impact force, and fire hydrant body 1 does not receive the impact. When the strong impact buffering is ineffective, the fire hydrant body 1 is damaged. The foam rubber ring 16 has small volume when sealed, and can react quickly after contacting air and water, expand in volume and quickly solidify to fill the space. When the fire hydrant body 1 is strongly impacted, the buffer device 5 also generates distortion, the needle head of the limiting needle 15 punctures the flexible waterproof layer 17 of the foam rubber ring 16, so that the foam rubber ring 16 rapidly expands and solidifies, the outlet of the underground water pipe 9 is blocked and solidified, and the water in the water pipe is prevented from being sprayed without control. Reserve dehydrating unit connects in the side of underground water pipe 9, exit and ground level, and with water pipe lid 10 threaded connection, waterproof gasket 11 is pressed from both sides to the centre, guarantees not can not leak when not initiatively opening, opens when needing to use and links fire-fighting water pipe, can in time supply water.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
