Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, specifically a fire hydrant drip alarm device. Background Technology

[0002] Fire hydrants are divided into indoor and outdoor fire hydrants. Indoor fire hydrants are usually connected to hoses and nozzles for easy access to the fire. Outdoor fire hydrants, on the other hand, primarily supply water and need to be connected to hoses on fire trucks for long-distance firefighting. Fire hydrants are prone to leaks after prolonged periods of disuse. Therefore, to reduce water waste, leak alarms are necessary. However, existing leak alarm devices still have the following drawbacks in practical use:

[0003] Traditional fire hydrants use liquid sensors to detect leaks. However, water may remain at the outlet of the fire hydrant after use, leading to inaccurate detection. Furthermore, the installation of the leak alarm device on the fire hydrant is not convenient or quick. To address these issues, there is an urgent need for innovative designs based on existing leak alarm devices. Utility Model Content

[0004] The purpose of this utility model is to provide a fire hydrant drip alarm device to solve the problems mentioned in the background art, where traditional fire hydrants use liquid sensors to alarm for dripping phenomena. However, after use, water remains at the outlet of the fire hydrant, resulting in inaccurate detection. Furthermore, the installation of the drip alarm device with the fire hydrant is not convenient or quick.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire hydrant drip alarm device, comprising a fire hydrant, wherein protective covers are provided on both sides of the upper end of the fire hydrant, and the protective covers are composed of movable sleeves and connecting covers;

[0006] It also includes: a water storage box, fixed below the connecting cover, the bottom of the water storage box is connected to the fixing box via a connecting hose, and the fixing box is symmetrically installed on both sides of the lower end of the fire hydrant. The fixing box has a fixing cavity inside, and a movable plate is installed inside the fixing cavity. An alarm is installed on the inner bottom surface of the fixing box.

[0007] A connecting mechanism is provided between the fire hydrant and the fixing box, and the connecting mechanism is used for the installation and removal of the fixing box.

[0008] Preferably, the movable sleeve and the water outlets on both sides of the fire hydrant are threadedly connected, and the movable sleeve and the connecting cover are rotatably connected. A one-way water outlet is provided between the connecting cover and the water storage box. When the movable sleeve is rotated, it can be connected to the fire hydrant, while the connecting cover can remain stationary.

[0009] Preferably, the water storage box is interconnected with the interior of the fixed cavity via a connecting hose, and the protective cover, water storage box and fixed box are symmetrically arranged about the vertical axis of the fire hydrant. The edge of the movable plate slides against the inner wall of the fixed box, so that when water drips from the fire hydrant outlet, it can enter the water storage box and then be transmitted to the fixed cavity through the connecting hose.

[0010] Preferably, the connecting mechanism includes a movable rod that passes through the side wall of the fixed box, and the movable rod and the fixed box are slidably connected. A spring is wound around the outside of the movable rod to reset it. When the movable rod is pushed, it can slide on the fixed box and drive the guide block to move.

[0011] Preferably, a guide block is fixedly connected to the end of the movable rod, and the guide block has a frustum-shaped structure. The inclined surface of the guide block is attached to one end of the connecting plate. After the guide block moves, it can contact the connecting plate and push the connecting plate to slide on the fixed box.

[0012] Preferably, the other end of the connecting plate is provided with a magnetic block via a track, and the connecting plate is connected to the inner wall of the fixed box by a spring. When the connecting plate moves, it drives the magnetic block to move synchronously.

[0013] Preferably, both the connecting plate and the magnetic block are slidably connected to the fixed box, and the magnetic block is flush with the surface of the fixed box. After the connecting plate is raised, it docks with the track on the surface of the fixed box. When the magnetic block moves to the surface of the fixed box, it can be pushed to slide on the track.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the fire hydrant drip alarm device can avoid the phenomenon of inaccurate detection caused by residual water at the outlet after the fire hydrant has been used, thus greatly improving the accuracy of the drip alarm. Furthermore, the drip alarm device can be quickly installed with the fire hydrant, facilitating subsequent use. Specific details are as follows:

[0015] 1. After the liquid enters the fixed cavity, the pressure on the movable plate increases continuously, causing it to slide down. Therefore, even if there is some residual liquid at the fire hydrant outlet, it will not cause the movable plate to descend rapidly after entering the fixed cavity. Only after the liquid has been dripping for a long time can it cause the movable plate to descend and make contact with the alarm to sound an alarm.

[0016] 2. Pushing the fixing box allows the outer wall of the fire hydrant to move the movable rod. The guide block can push the two connecting plates away from each other. When the connecting plate moves the magnetic block to the surface of the fixing box, the track on the connecting plate is aligned with the track on the fixing box. This allows the magnetic block to slide from the connecting plate to the fixing box when pushed, and magnetically connect with the fire hydrant, thus achieving stable installation of the fixing box.

[0024] 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.

[0025] Please see Figures 1-6 The present invention provides the following technical solution:

[0026] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a fire hydrant drip alarm device, comprising a fire hydrant 1, with protective covers 2 on both sides of the upper end of the fire hydrant 1, and the protective covers 2 consisting of a movable sleeve 21 and a connecting cover 22; further comprising: a water storage box 3, fixed below the connecting cover 22, the bottom of the water storage box 3 being connected to a fixed box 5 via a connecting hose 4, and the fixed box 5 being symmetrically installed on both sides of the lower end of the fire hydrant 1, the fixed box 5 having a fixed cavity 6 inside, and a movable plate 7 inside the fixed cavity 6, and an alarm 8 installed on the inner bottom surface of the fixed box 5; and a connecting mechanism, disposed between the fire hydrant 1 and the fixed box 5, the connecting mechanism being used for the installation and disassembly of the fixed box 5.

[0027] Existing fire hydrants use liquid sensors to detect leaks. However, moisture remains at the outlet of the hydrant after use, leading to inaccurate detection. Figures 1-2 and Figures 5-6 As shown, the movable sleeve 21 and the outlets on both sides of the fire hydrant 1 are threadedly connected, and the movable sleeve 21 and the connecting cover 22 are rotatably connected. A one-way outlet is provided between the connecting cover 22 and the water storage box 3. The water storage box 3 is interconnected with the interior of the fixed cavity 6 via the connecting hose 4. The protective cover 2, the water storage box 3, and the fixed box 5 are all symmetrically arranged about the vertical axis of the fire hydrant 1, and the edge of the movable plate 7 slides against the inner wall of the fixed box 5. When the fire hydrant 1 needs to be used, the movable sleeve 21 can be rotated to separate it from the outlet position of the fire hydrant 1. After use, the movable sleeve 21 can be rotated back to connect to the fire hydrant 1. During rotation, the connecting cover 22 remains stationary, thus not affecting... The connection of the movable sleeve 21 does not affect the position of the water storage box 3. When liquid drips from the outlet of the fire hydrant 1, the liquid can enter the water storage box 3 through the connecting cover 22. Since there is a one-way outlet between the two, backflow of liquid can be avoided. Then the liquid can enter the fixed cavity 6 of the fixed box 5 through the connecting hose 4. After the liquid enters the fixed cavity 6, the pressure on the movable plate 7 increases continuously, and it can slide down in the fixed cavity 6. Therefore, even if there is some residual liquid at the outlet of the fire hydrant 1, it will not cause the movable plate 7 to fall quickly after entering the fixed cavity 6. Only after the liquid drips for a long time accumulates can it cause the movable plate 7 to fall and contact the alarm 8 to sound an alarm.

[0028] Example 2: The installation of existing drip alarm devices with fire hydrants is not convenient or quick enough. Therefore, this example uses the following technical solution, such as... Figures 3-6As shown, the connecting mechanism includes a movable rod 9 that passes through the side wall of the fixed box 5, and the movable rod 9 and the fixed box 5 are slidably connected. A spring is wound around the outside of the movable rod 9 to return it to its original position. A guide block 10 is fixedly connected to the end of the movable rod 9. The guide block 10 has a frustum-shaped structure, and the inclined surface of the guide block 10 is attached to one end of the connecting plate 11. A magnetic block 12 is provided at the other end of the connecting plate 11 via a track, and the connecting plate 11 is connected to the inner wall of the fixed box 5 by a spring. Both the connecting plate 11 and the magnetic block 12 are slidably connected to the fixed box 5, and the magnetic block 12 is flush with the surface of the fixed box 5. After the connecting plate 11 is raised, it aligns with the track on the surface of the fixed box 5. When the fixed box 5 needs to be installed, its inner concave surface is aligned with the outer surface of the fire hydrant 1. The wall is in contact with the fixed box 5, which pushes the outer wall of the fire hydrant 1 to move the movable rod 9. The movable rod 9 drives the guide block 10 to move synchronously. The guide block 10 can push the two connecting plates 11 away from each other. In this way, the connecting plate 11 drives the magnetic block 12 to slide on the fixed box 5. When the magnetic block 12 moves to the surface of the fixed box 5, the track on the connecting plate 11 is aligned with the track on the fixed box 5. Thus, when the magnetic block 12 is pushed, it can slide from the connecting plate 11 to the fixed box 5 and magnetically connect with the fire hydrant 1, realizing the stable installation of the fixed box 5. Subsequent disassembly is also very convenient. Separate the magnetic block 12 from the fire hydrant 1 to reconnect it with the connecting plate 11, and then separate the fixed box 5 from the fire hydrant 1 to achieve disassembly.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
