Description

Technical Field

[0001] This utility model relates to the field of underground concealed fire hydrant technology, specifically an underground concealed fire hydrant. Background Technology

[0002] Concealed fire hydrants are fire-fighting facilities designed to combine aesthetics and practicality. They ensure rapid and effective use in emergencies without compromising the overall visual appeal of the building or environment.

[0003] Chinese patent disclosure (CN214194777U) discloses an underground concealed fire hydrant for fire fighting. It includes a mounting box with a housing fixedly mounted at the bottom. A motor is fixedly mounted on one side of the housing, and a rotating shaft is fixedly connected to the motor's output end. A first bevel gear is fixedly mounted on the outer side of the rotating shaft, and a second bevel gear meshes with the surface of the first bevel gear. A threaded rod is fixedly mounted on the upper side of the second bevel gear. Support plates are fixedly mounted on both sides of the inner wall of the mounting box. A movable plate is threadedly connected to the outer side of the threaded rod, and the fire hydrant body is fixedly mounted on the upper side of the movable plate. A water inlet pipe is provided at the bottom of one side of the fire hydrant body. This invention uses a motor to control the rotation direction of the rotating shaft, which drives the movable plate to rise and fall, thus facilitating the adjustment of the height of the fire hydrant body. When the fire hydrant body is not in use, it can be concealed below ground level, protecting the hydrant body while saving floor space and improving the practicality of the device.

[0004] However, it still has the following drawbacks: rainwater containing electrolytes easily causes fire hydrants to corrode, and in existing technologies, both cover plates are hinged to the inner wall of the mounting box, making it difficult to maintain a tight seal between the two cover plates and between the cover plates and the mounting box, thus negating the purpose of concealing and protecting the fire hydrant. Therefore, we propose an underground concealed fire hydrant to solve this problem. Utility Model Content

[0005] The purpose of this utility model is to provide an underground concealed fire hydrant to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an underground concealed fire hydrant, comprising a fire hydrant, wherein an installation device is provided on the outside of the fire hydrant, and the installation device includes a sealing part;

[0007] The sealing part includes an operating rod, a limiting rod, a mounting box, and a rotating shaft. The inner wall of the mounting box has a groove. The outer surface of the bottom end of the rotating shaft rotates through the top surface of the mounting box and extends into the groove via a bearing. The operating rod and the limiting rod are both fixedly sleeved on the outer surface of the rotating shaft.

[0008] The mounting box is equipped with a lifting mechanism;

[0009] The lifting unit includes a sliding rod and a mounting plate. The outer surface of the sliding rod is fixedly connected to the inner wall of the mounting box. The mounting plate is slidably sleeved on the outer surface of the sliding rod. The bottom surface of the fire hydrant is fixedly connected to the top surface of the mounting plate.

[0010] A further improvement is that the sealing part also includes fixing bolts, a cover plate, a sealing gasket, and a U-shaped frame. The outer surface of the U-shaped frame is fixedly connected to the inner wall of the mounting box, the bottom surface of the sealing gasket is fixedly connected to the top surface of the U-shaped frame, the inner wall of the mounting box is adapted to the outer surface of the cover plate, and the cover plate is opened and closed by moving up and down. The sealing gasket improves the sealing performance between the cover plate and the mounting box.

[0011] A further improvement is that a fan-shaped positioning groove is formed on the outer surface of the cover plate, and the outer surface of the limiting rod extends into the fan-shaped positioning groove and slides in connection with the inner wall of the cover plate. The bottom surface of the limiting rod is in contact with the inner wall of the cover plate. By setting a rotating shaft, an operating rod and a limiting rod, rotating the operating rod drives the limiting rod to rotate, so that the limiting rod limits the cover plate and simultaneously presses the cover plate downward, thereby improving the sealing between the cover plate and the mounting box and improving the protective effect on the fire hydrant.

[0012] A further improvement is that the outer surface of the operating rod is provided with a threaded hole, and the outer surface of the bottom end of the fixing bolt extends into the threaded hole and is adapted to the inner wall of the threaded hole. By setting the fixing bolt, it is easy to position the operating rod. In use, rotating the fixing bolt and then rotating the operating rod can control the opening of the cover plate, thereby improving the convenience of using the device.

[0013] A further improvement is that the lifting unit also includes a wire rope, a take-up roller, a mounting shaft, and a positioning rod. The outer surface of the mounting shaft is rotatably connected to the inner wall of the mounting box via a bearing seat. The take-up roller is fixedly sleeved on the outer surface of the mounting shaft. The bottom end of the wire rope is fixedly connected to the top surface of the mounting plate, and the top end of the wire rope is fixedly connected to the inner wall of the take-up roller. By setting up the mounting shaft, the take-up roller, and the wire rope, rotating the mounting shaft will pull the mounting plate and the fire hydrant upward through the wire rope, so that the top of the fire hydrant is moved above the ground for easy use by firefighters.

[0014] A further improvement is that the outer surface of the mounting plate has a through groove, the outer surface of the positioning rod extends into the interior of the mounting plate and slides in connection with the inner wall of the mounting plate, the inner wall of the mounting box has a positioning groove, the bottom surface of the positioning rod has a groove, and the inner wall of the positioning rod is adapted to the inner wall of the positioning groove. By setting the positioning rod, it is convenient to position the mounting plate.

[0015] A further improvement is that a flexible hose is fixedly connected to the front of the fire hydrant inlet pipe, and a main water pipe is fixedly connected to the front of the flexible hose. A valve is installed on the main water pipe. The outer surface of the main water pipe is fixedly penetrated through the inner wall of the installation box and extends to the front of the installation box. The flexible hose facilitates the connection between the fixed main water pipe and the movable fire hydrant. The valve controls the water flow. When the valve is closed, the internal pressure of the flexible hose is reduced, thereby increasing the service life of the flexible hose.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This underground concealed fire hydrant is equipped with an operating lever, fixing bolts, a limit rod, a rotating shaft, a cover plate, a mounting box, a sealing gasket, and a U-shaped frame. The sealing gasket is used to seal the cover plate and the mounting box. By rotating the operating lever, the limit rod moves into the inside of the cover plate and presses down on the cover plate, causing the cover plate to squeeze the sealing gasket downwards. The fixing bolts are used to position the two operating levers. By first rotating the fixing bolts and then rotating the operating levers, the cover plate can be removed upwards, which facilitates the opening and closing of the cover plate and improves the convenience of use.

[0018] By setting up a slide bar, wire rope, take-up roller, mounting shaft, positioning rod, and mounting plate, the wire rope is wound around the take-up roller by rotating the mounting shaft. The front end of the positioning rod is used to lock the inner wall of the mounting box, so that the top of the fire hydrant can be moved upward to above the ground for easy use by firefighters.

[0019] By installing a main water pipe, valves, and hoses, the valves are closed under normal conditions to reduce the pressure inside the hoses and extend their service life. Attached Figure Description
