Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, specifically a protective device for an outdoor fire hydrant. Background Technology

[0002] Firefighting equipment refers to equipment used for extinguishing fires, preventing fires, and handling fire accidents. Common firefighting equipment includes: portable fire extinguishers, fire blankets, smoke masks, escape ropes, descent devices, and fire hydrants.

[0003] In the prior art, Chinese utility model publication number CN214116811U discloses a fire hydrant with a protective device, belonging to the field of fire hydrant technology. It includes a protective cover, a waterproof cover fitted to the outer wall of the protective cover, a warning light fixedly mounted on the upper end of the protective cover, fixed seats fixedly mounted on both sides of the outer wall of the protective cover, an opening in the middle of the waterproof cover, reflective strips tightly fitted to the outer wall of the waterproof cover, a limit rod fixedly mounted inside the protective cover, and a fire hydrant body fixedly mounted inside the protective cover. A top valve is fitted to the upper end of the fire hydrant body, and a water outlet valve is fitted to the middle of the fire hydrant body. This utility model utilizes the properties of the steel material of the protective cover, allowing it to withstand impacts from all directions on the fire hydrant body, protecting it from damage. The waterproof cover's waterproof properties protect the outdoor fire hydrant body from rain, reducing corrosion and extending its service life.

[0004] In the above technical solution, the protective cover is supported by a limiting and fixing rod, and then an opening is made on the protective cover to connect the fire hydrant body to the outside. However, if the opening is too small, it is inconvenient to operate; if the opening is too large, it reduces the protective effect. If the protective cover is removed and the fire hydrant body is used, the operation becomes more complicated and affects the use of the fire hydrant body. Utility Model Content

[0005] The purpose of this utility model is to provide a protective device for an outdoor fire hydrant. The device connects a top cover to a lifting column, which moves a pin up and down. This allows for easy adjustment of the protective plate via a fixing plate. Normally, the protective plate is engaged with the support frame, protecting the hydrant body. When the hydrant body needs to be used, simply move the top cover upwards, which in turn moves the lifting column upwards, removing the pin from the fixing plate. This allows the protective plate to separate from the support frame, facilitating the use of the hydrant body and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective device for an outdoor fire hydrant, comprising a cement ground, a fire hydrant body extending upward from the cement ground, a base frame installed on the top of the cement ground, support frames fixed around the top of the base frame, protective plates hinged around the top of the base frame, the protective plates engaging with the support frames, a top cover movably mounted on the top of the support frames, fixing plates fixed sequentially from top to bottom on the inner side of the protective plates, slots corresponding to the fixing plates on the support frames, a lifting column movably mounted inside the support frames, a pin fixed to the outer side of the lifting column, a limiting hole engaging with the pin on the fixing plate, and the top of the lifting column connected to the top cover.

[0007] Preferably, a connecting plate is fixed to the bottom of the lifting column, a traction spring is fixed to the bottom of the connecting plate, and the bottom of the traction spring is fixed to the bottom of the inner cavity of the support frame.

[0008] Preferably, the cement floor is provided with multiple sets of upward-extending bolt columns, which pass through the base frame and are threadedly connected with mounting nuts.

[0009] Preferably, a limiting block is fixed in the inner cavity of the support frame, and the limiting block is located above the connecting plate.

[0010] Preferably, the bottom of the top cover is fixed with a mounting base, and the mounting base is detachably connected to the lifting column by connecting bolts.

[0011] Preferably, the outer sides of the two sets of protective plates are provided with markings, and the outer sides of the other two sets of protective plates are provided with reflective stickers.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses the top cover to drive the lifting column upward, thereby driving the pin fixed on the lifting column to move out of the limiting hole on the fixing plate, which facilitates the release of the fixing plate. This allows the protective plate to be separated from the support frame. At this time, the protective plate can be flipped over by the hinge, opening up the space around the fire hydrant body, which facilitates the operation of the fire hydrant body. At the same time, the top cover and the lifting column can be disassembled, improving the rapid conversion between use and protection of the fire hydrant.

[0014] 2. This utility model avoids the base frame being removed, thus preventing the fire hydrant body from losing its protection, by placing the bolt column and mounting nut inside the protective plate. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figures 1-6 The protective device for an outdoor fire hydrant shown includes a cement ground 1, a fire hydrant body 2 extending upward from the cement ground 1, a base frame 3 installed on the top of the cement ground 1, support frames 4 fixed around the top of the base frame 3, a protective plate 5 hinged around the top of the base frame 3, the protective plate 5 being snapped into the support frame 4, a top cover 6 movably installed on the top of the support frame 4, a fixing plate 7 fixed from top to bottom on the inner side of the protective plate 5, a slot 8 corresponding to the position of the fixing plate 7 on the support frame 4, a lifting column 9 movably installed in the inner cavity of the support frame 4, a pin 10 fixed on the outer side of the lifting column 9, a limiting hole 11 for engaging with the pin 10 on the fixing plate 7, and the top of the lifting column 9 being connected to the top cover 6.

[0024] The top cover 6 drives the lifting column 9 to move upward, thereby moving the pin 10 fixed on the lifting column 9 and causing the pin 10 to move out of the limiting hole 11 on the fixing plate 7, which facilitates the release of the fixing plate 7. This allows the protective plate 5 to be separated from the support frame 4. At this time, the protective plate 5 is flipped by the hinge, opening up the space around the fire hydrant body 2, which facilitates the operation of the fire hydrant body 2. At the same time, the top cover 6 and the lifting column 9 can be disassembled, improving the rapid conversion between use and protection of the fire hydrant.

[0025] A connecting plate 12 is fixed to the bottom of the lifting column 9, and a traction spring 13 is fixed to the bottom of the connecting plate 12. The bottom of the traction spring 13 is fixed to the bottom of the inner cavity of the support frame 4. Through the cooperation of the traction spring 13 and the connecting plate 12, the lifting column 9 can be pulled to move downward, thus preventing the lifting column 9 from shaking up and down and causing the pin 10 to separate from the fixing plate 7.

[0026] Multiple sets of upward-extending bolt posts 14 are installed inside the cement floor 1. The bolt posts 14 pass through the base frame 3 and are threadedly connected to the mounting nuts 15. Through the cooperation of the bolt posts 14 and the mounting nuts 15, the base frame 3 can be easily installed on the cement floor 1. At the same time, it is used to fix the base frame 3 and the support frame 4 so that they are stable with the fire hydrant body 2 and to provide protective support for the fire hydrant body 2.

[0027] A limiting block 16 is fixed in the inner cavity of the support frame 4. The limiting block 16 is located above the connecting plate 12. By setting the limiting block 16, the upward movement distance of the lifting column 9 is limited, so as to prevent the traction spring 13 from being overstretched and losing its elasticity.

[0028] The bottom of the top cover 6 is fixed with a mounting base 17. The mounting base 17 and the lifting column 9 are detachably connected by connecting bolts. The lifting column 9 and the mounting base 17 are connected by connecting bolts, so that the lifting column 9 and the top cover 6 can be quickly assembled and disassembled.

[0029] The outer sides of the two sets of protective panels 5 are marked with signs 18, and the outer sides of the other two sets of protective panels 5 are marked with reflective stickers 19. The signs 18 indicate to pedestrians that there is a fire hydrant body 2 inside the protective area, and the reflective stickers 19 are used to reflect light and prevent collisions with the fire hydrant body 2 at night.

[0030] In practical use, the base frame 3 is installed on the outside of the fire hydrant body 2 using the mounting nut 15 and bolt column 14. At the same time, the top cover 6 is pulled upward, and the top cover 6 drives the lifting column 9 to move upward. Then, the protective plate 5 is flipped upward, so that the protective plate 5 is snapped onto the outside of the support frame 4. At the same time, the fixing plate 7 on the protective plate 5 passes through the slot 8 and enters the interior of the support frame 4. Then, the top cover 6 is released, so that the lifting column 9 moves downward under the traction of the traction spring 13, so that the pin 10 on the lifting column 9 passes through the limiting hole 11 on the fixing plate 7 to limit the fixing plate 7, so that the protective plate 5 is stably connected to the support frame 4 to protect the fire hydrant body 2. When the fire hydrant body 2 needs to be used, simply move the top cover 6 upward, so that the lifting column 9 drives the pin 10 to separate from the fixing plate 7. At this time, the protective plate 5 can be flipped by the hinge, so that the fire hydrant body 2 is hollowed out on all sides, making it easy to use the fire hydrant body 2.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
