Detailed Description

The utility model will be further described with reference to the drawings and examples.

As shown in fig. 1 and 2, the fire hydrant box of the present utility model comprises a box body 1, a hydrant body 2 and a lifting control mechanism 6. The top of the box body 1 is provided with an opening 11, a water pipe joint 3 for an external water supply pipe is arranged on the bottom plate of the box body 1, and one end of the water pipe joint 3 penetrates through the bottom plate of the box body 1 and extends out of the box body 1. The fire hydrant mounting frame 4 which is vertically and slidably connected with the box body 1 is arranged in the box body 1, and the fire hydrant mounting frame 4 is particularly connected with the box body 1 in a vertical sliding way through two guide posts 7 which are arranged in the box body. The fire hydrant body 2 is installed on the fire hydrant mounting frame 4, the water inlet of the fire hydrant body 2 is connected with the inner end (the end positioned in the box body 1) of the water pipe joint 3 through a telescopic connecting pipe 5, and the lifting control mechanism 6 is connected with the fire hydrant mounting frame 4 to control the fire hydrant mounting frame 4 to slide vertically.

It will be appreciated that the telescopic length of the connection pipe 5 should be matched to the vertical sliding distance of the hydrant mount 4.

The fire hydrant box is mainly used for the occasion of installing an underground fire hydrant, namely, the box body 1 is buried under the ground when being installed. When the fire hydrant box is used, the fire hydrant installation frame 4 can be controlled to slide upwards to a certain height through the lifting control mechanism 6, so that the fire hydrant body 2 installed on the fire hydrant installation frame 4 extends out of the box body 1 and is higher than the ground, the operation space is enlarged, and fire extinguishing operations such as butt joint of a fire hydrant and a fire hydrant are facilitated. When the fire is extinguished, the lifting control mechanism 6 can control the fire hydrant mounting frame 4 to slide downwards so that the fire hydrant body 2 is retracted into the box body 1, and the fire hydrant body 2 is prevented from being damaged due to the influence of accidents such as collision. In the utility model, the connecting pipe 5 is of a telescopic structure, so that the connecting pipe 5 can be correspondingly lengthened or shortened in the vertical sliding process of the fire hydrant mounting frame 4.

The hydrant body 2 may be mounted on the hydrant mount 4 by welding or bolting, but the above-described manner is liable to cause damage to the hydrant body 2 and is inconvenient for replacement when the hydrant body 2 is damaged. In the embodiment of the present utility model, as shown in fig. 2, the hydrant mounting frame 4 is provided with a left clamping piece 41 and a right clamping piece 42, the left clamping piece 41 and the right clamping piece 42 are both in an arc structure and are horizontally and oppositely arranged, the left clamping piece 41 and the right clamping piece 42 are connected and enclosed by a bolt 43 to form a hydrant mounting hole 44, and the hydrant body 2 is clamped and fixed in the hydrant mounting hole 44. The left clamping piece 41 and the right clamping piece 42 are horizontally arranged opposite to each other, that is, the left clamping piece 41 and the right clamping piece 42 are horizontally arranged with the concave surfaces opposite to each other. The fixing mode can enable the left clamping piece 41 and the right clamping piece 42 to deform to a certain extent through the bolts 43, so that the fire hydrant body 2 is tightly held, the fire hydrant body 2 is not easy to damage, and the fire hydrant body 2 is convenient to assemble, disassemble and replace.

In some embodiments, left grip tab 41 and right grip tab 42 are fixedly secured to hydrant mount 4. Because the pipe diameters of different fire hydrants may be different, for better fixing the fire hydrants and adapting to installing fire hydrants with different pipe diameters, as shown in fig. 2, the right clamping piece 42 is fixedly connected with the fire hydrant mounting frame 4, and the left clamping piece 41 is slidably connected with the fire hydrant mounting frame 4 along a direction away from or approaching the right clamping piece 42. Thus, when in use, the left clamping piece 41 can be slid according to actual needs to adjust the distance between the left clamping piece 41 and the right clamping piece 42, and the size of the fire hydrant mounting hole 4 can be adjusted to adapt to the fire hydrants with different pipe diameters or better clamp and fix the fire hydrant on the fire hydrant mounting frame 4. In addition, because the right clamping piece 42 is fixedly connected with the fire hydrant mounting frame 4, the fire hydrant body 2 can be prevented from swaying left and right in the box body 1, and the butt joint of the fire hydrant and the fire hydrant is facilitated. Wherein, the fixed connection can adopt modes of welding, bolt connection and the like.

In the embodiment of the present utility model, the left grip 41 is slidably connected to the hydrant mount 4 in a direction away from or toward the right grip 42, specifically, through a telescopic rod and the hydrant mount 4.

Specifically, the connection pipe 5 may be made of various kinds of existing hoses or bellows, and may be made telescopic. In the embodiment of the present utility model, the connection pipe 5 is a bellows.

The lifting control mechanism 6 may be a cylinder, a jack, or the like. In an embodiment of the present utility model, as shown in fig. 2 and 3, the lifting control mechanism 6 includes a self-locking screw rod 61 vertically disposed in the box 1, the self-locking screw rod 61 includes a screw rod section 611 and a hexagonal head section 612 disposed at an upper end of the screw rod section 611, the self-locking screw rod 61 is rotationally connected with the box 1, and the screw rod section 611 is in threaded fit with the hydrant mounting frame 4 through threads thereof. Thus, rotation of the hex head section 612 by a wrench may move the hydrant mount 4 up and down along the lead screw section 611 by the lead screw section 611. And because the screw rod is self-locking, the fire hydrant mounting frame 4 can not fall down by itself under external force.

The structure is simple, but the self-locking screw rod has lower transmission efficiency and is more laborious to operate. In another embodiment of the present utility model, as shown in fig. 4, the lifting control mechanism 6 includes a rack 62 and a rotating shaft 63 rotatably installed above the case 1 and horizontally disposed, the rack 62 is vertically fixed on the hydrant mount 4, the rotating shaft 63 is disposed on one side of the rack 62 and is meshed with the rack 62 through a gear 64, a hand wheel 65 is disposed at one end of the rotating shaft 63, and a locking mechanism 66 that cooperates with the case 1 to lock the position of the hand wheel 65 is disposed on the hand wheel 65. When the lifting control mechanism 6 works, the rotating shaft 63 can be rotated through the wrench 65, and the rotating shaft 63 drives the fire hydrant mounting frame 4 to move up and down through the gear 64 and the rack 62 in the rotating process. When the fire hydrant mounting frame 4 moves in place, the hand wheel 65 can be locked through the locking mechanism 66 matched with the box body 1, and then the position of the fire hydrant mounting frame 4 is locked. The lifting control mechanism 6 is relatively more labor-saving, but is relatively complex in structure.

Specifically, the locking mechanism 66 may be a latch, bolt, screw, or any of a variety of existing locks.

In order to better protect the hydrant body 2, the box body 1 of the present utility model is provided with a cover 12 which is matched with the opening 11. The cover 12 may be hinged to the housing.
