Description

A concealed fire hydrant

technical field

The utility model relates to the technical field of fire protection facilities, in particular to a concealed fire hydrant.

Background technique

Fire hydrants are also called fire hydrants, which are divided into indoor fire hydrants and outdoor fire hydrants. Fire hydrants are mainly used for fire trucks to take water from the municipal water supply pipe network or outdoor fire water supply pipe network to extinguish fires, and can also be directly connected to water hoses and water guns to extinguish fires. Therefore, indoor and outdoor fire hydrant systems are also one of the important fire fighting facilities for fire fighting.

Outdoor fire hydrants are divided into above-ground fire hydrants and underground fire hydrants. The above-ground fire hydrant is fixed on the ground, which is easy to use, but not beautiful, and it is easy to trip over pedestrians or cause traffic accidents to cause safety hazards; at the same time, due to the influence of external natural or human factors, fire hydrants are prone to damage, resulting in waste of resources. Make it unable to play its auxiliary fire-fighting role, posing a huge safety hazard to citizens' personal and property safety. Although the underground fire hydrant partially solves the above problems, it requires the user to go down the well to connect and install the fire hose. Due to the narrow underground space, the installation is inconvenient, so the efficiency is low, which may delay the appropriate fire fighting time. Its convenience of use Far better than above ground fire hydrants.

Utility model content

In view of the above-mentioned defects of the prior art, the purpose of the utility model is to provide a concealed fire hydrant, which is installed underground when not in use, and can be partially lifted to the ground when in use, which is convenient to use and eliminates potential safety hazards. The concealed fire hydrant has a simple structure, is not easy to corrode, has a long service life and a low failure rate.

In order to achieve the above-mentioned technical effect, the utility model adopts the following technical solutions:

A concealed fire hydrant includes an installation box, the lower part of the installation box is provided with a through hole, the through hole is convenient for the water supply pipe network to extend into the inside of the box body and the soft water pipe to be connected to the concealed The fire hydrant body and the support table are installed inside the installation box. The fire hydrant body is at least provided with a water outlet and a lifting handle. The lower part of the water outlet is a connecting part, and the connecting part The outer side is fixedly connected with a connecting column, the bottom of the connecting column is provided with an inward convex block, and the lower part of the fire hydrant body is connected with the water supply pipe network through a soft water pipe, and the length of the soft water pipe is greater than the length of the The height of the installation box, the support platform is arranged at the lower part of the fire hydrant, its main body is a hollow cylindrical structure and is sleeved outside the fire hydrant body, and at least one support portion is provided outside the support platform. When the concealed fire hydrant is installed, the box body is pre-buried in the ground. When in use, the fire hydrant body is moved upward for a certain distance by pulling the lifting handle, and the bottom of the connecting column is rotated by rotating the lifting handle. The raised part is located above the support part and is on the same vertical line as the support part, the lifting handle is released, the protrusion at the bottom of the connecting column is in close contact with the support part, and the fire hydrant is in close contact with the support part. The main body is fixed on the horizontal plane. The concealed fire hydrant has a simple structure, which greatly reduces the probability of failure. The operation method is simple and easy, and even a novice can operate it smoothly.

Further, the support portion includes one or more groups, each group includes two or more support portions, each group of support portions is arranged at different heights of the support table, and the multiple groups of support portions can be Fix the hydrant body at different heights.

Further, the top of the support table is provided with a first limit block, and the function of the limit block is to prevent the fire hydrant from being separated from the support table.

Further, a base is fixedly connected to the bottom of the support table, a through hole is provided on the top of the base, the diameter of the through hole is equal to the inner diameter of the support table, and the inside of the base is a cavity, and the hollow The cavity is used to accommodate the flexible water pipe.

Further, a protective cover plate is also installed on the upper part of the installation box, and a through hole is provided on the protective cover plate, and the through hole makes the protective cover plate easy to open, when the concealed fire hydrant is not used, The protective cover plate cooperates with the box body so that the concealed fire hydrant is in a relatively closed space, which can reduce the corrosion of the fire hydrant.

Further, a second limit block is provided on one side of the support portion, and the second limit block is used to limit the rotation angle of the fire hydrant body, so that the support platform achieves a better support effect.

As can be seen from the above-mentioned technical effects, the beneficial effects of the present utility model are:

On the one hand, the concealed fire hydrant is arranged below the ground, which can greatly reduce man-made damage and slow down its failure due to environmental conditions, and avoid the need for existing buried fire hydrants to manually enter the fire well for connection and fire fighting before use. Due to the inconvenience of the hose, especially when a single person needs to go down the well to connect multiple water outlets, the concealed fire hydrant provided by the utility model can greatly improve the connection efficiency.

On the other hand, compared with other existing buried fire hydrants, the concealed fire hydrant can not only achieve the technical effect of lifting the fire hydrant body above the ground, but also simplify its structure and avoid the use of complex machinery The structure can greatly reduce the loss of the entire lifting function caused by the failure of the mechanism, and greatly improve the reliability of its function.
