Description

Technical Field

[0001] The utility model relates to the technical field of fire hydrants, and particularly relates to a safety protection device for an outdoor fire hydrant. Background Art

[0002] A fire hydrant, officially called a fire plug, is a fixed fire-fighting facility. Its main functions are to control combustibles, isolate combustion-supporting substances, and eliminate ignition sources. It is divided into indoor fire hydrants and outdoor fire hydrants.

[0003] At present, most of the outdoor fire hydrant protection devices on the market mainly focus on the overall functions of rain protection, dust protection, and anti-theft, while the protection of the valve stem, a key component, is relatively weak. Since the valve stem is exposed outdoors for a long time, it is easily eroded by rain, accumulated with dust, and damaged by humans, resulting in problems such as rusting and jamming, which affect the normal opening and use of the fire hydrant. Although some fire hydrants are provided with simple protective covers or covers at the valve stem, these designs often have the problem of inconvenient opening. In case of an emergency, firefighters need to spend extra time and energy to open the protection device, which may delay the fire extinguishing opportunity. Therefore, we propose a safety protection device for an outdoor fire hydrant. Content of the Utility Model

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and to provide a safety protection device for an outdoor fire hydrant, which can solve the problems that due to the valve stem being exposed outdoors for a long time, it is easily eroded by rain, accumulated with dust, and damaged by humans, resulting in problems such as rusting and jamming, which affect the normal opening and use of the fire hydrant. Although some fire hydrants are provided with simple protective covers or covers at the valve stem, these designs often have the problem of inconvenient opening. In case of an emergency, firefighters need to spend extra time and energy to open the protection device, which may delay the fire extinguishing opportunity.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: A safety protection device for an outdoor fire hydrant, comprising:

[0006] A fire hydrant body, the top flange of the fire hydrant body is connected with a valve stem, and the top of the valve stem is fixedly connected with a plug cap;

[0007] A protection component, the protection component is located on the valve stem;

[0008] The protection component includes a protection box, a hinge, a protection plastic plate, and a maintenance plate. The protection box is fixedly connected to the top of the valve stem. An installation chute is opened inside the protection box. An inspection slot is opened on one side of the protection box. The protection plastic plate is slidably installed inside the installation chute. The maintenance plate is rotatably installed on one side of the protection box through a hinge. A card slot is opened on one side of the inspection slot.

[0009] Preferably, a storage groove is formed on the side of the inspection plate away from the hinge. A lock core is rotatably connected inside the storage groove. A hook is fixedly connected to the side of the lock core close to the hinge, and the hook is adapted to the inside of the card slot.

[0010] Preferably, a water outlet pipe is welded to the outer surface of the fire hydrant body, and a sealing cover is installed on the water outlet pipe.

[0011] Preferably, a drain pipe is flange-connected to the bottom of the fire hydrant body.

[0012] Preferably, the protective plastic plate is made of a transparent and breakable material.

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

[0014] 1. For the safety protection device for the outdoor fire hydrant, through the cooperation of the protective plastic plate, the protective box and the inspection plate, a relatively hard tool or the heel can be used to break the protective plastic plate in an emergency. At the same time, when it is not an emergency or when the protective plastic plate needs to be replaced, the inspection plate can be rotated and opened, so as to facilitate the removal or replacement of the protective plastic plate. Therefore, while protecting the valve cap, it can also be quickly opened for use, further improving the practicability of the protection structure. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution: a safety protection device for an outdoor fire hydrant, including:

[0026] A fire hydrant body 1, the top flange of the fire hydrant body 1 is connected to a valve rod 4, and the top of the valve rod 4 is fixedly connected to a plug cap 9;

[0027] A protection component, the protection component is located on the valve rod 4;

[0028] The protection component includes a protection box 5, a hinge 12, a protection plastic plate 6 and a maintenance plate 7. The protection box 5 is fixedly connected to the top of the valve rod 4. An installation chute 10 is opened inside the protection box 5. A maintenance slot 11 is opened on one side of the protection box 5. The protection plastic plate 6 is slidably installed inside the installation chute 10. The protection plastic plate 6 is made of a transparent and breakable material. The maintenance plate 7 is rotatably installed on one side of the protection box 5 through the hinge 12. A card slot 13 is opened on one side of the maintenance slot 11.

[0029] On the side of the maintenance plate 7 away from the hinge 12, a storage groove 15 is provided. Inside the storage groove 15, a lock core 8 is rotatably connected. On the side of the lock core 8 close to the hinge 12, a hook 14 is fixedly connected. The hook 14 is adapted to the inside of the card slot 13. On the outer surface of the fire hydrant body 1, a water outlet pipe 3 is welded. A sealing cover is installed on the water outlet pipe 3. The bottom of the fire hydrant body 1 is flange-connected with a drain pipe 2.

[0030] Further, when using this device, when it is necessary to urgently use the fire hydrant body 1, the user can use a relatively hard tool or break the protective plastic plate 6 with the heel. Since the protective plastic plate 6 is made of plastic material, it will not generate a large resistance, thus facilitating the use of the fire hydrant body 1 in an emergency. In non-emergency situations or when the protective plastic plate 6 needs to be replaced, the user inserts the key into the lock core 8 and then turns the lock core 8, so that the lock core 8 can drive the hook 14 away from the card slot 13, thus facilitating the rotation and opening of the maintenance plate 7, and then facilitating the removal or replacement of the protective plastic plate 6.

[0031] Through the cooperation of the protective plastic plate 6, the protective box 5 and the maintenance plate 7, in an emergency, a relatively hard tool or the heel can be used to break the protective plastic plate 6. At the same time, in non-emergency situations or when the protective plastic plate 6 needs to be replaced, the maintenance plate 7 can be rotated and opened, thus facilitating the removal or replacement of the protective plastic plate 6. Therefore, while protecting the bolt cap 9, it can also be quickly opened for use, further improving the practicality of this protection structure.

[0032] Working principle: When it is necessary to urgently use the fire hydrant body 1, the user can use a relatively hard tool or break the protective plastic plate 6 with the heel. Since the protective plastic plate 6 is made of plastic material, it will not generate a large resistance, thus facilitating the use of the fire hydrant body 1 in an emergency. In non-emergency situations or when the protective plastic plate 6 needs to be replaced, the user inserts the key into the lock core 8 and then turns the lock core 8, so that the lock core 8 can drive the hook 14 away from the card slot 13, thus facilitating the rotation and opening of the maintenance plate 7, and then facilitating the removal or replacement of the protective plastic plate 6.

[0033] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the said technical field, various changes can be made without departing from the purpose of the present invention.
