Description

Technical Field

[0001] This utility model relates to the field of fire hydrant technology, specifically a fire sprinkler hydrant designed to prevent accidental activation. Background Technology

[0002] A fire hydrant is a fixed fire-fighting facility whose main function is to provide a water source for extinguishing fires. It can quickly provide firefighters with a large and stable supply of water, which can be connected to hoses and nozzles for firefighting operations, effectively controlling and extinguishing fires and preventing their spread. At the same time, outdoor fire hydrants can also replenish water for fire trucks, ensuring that fire trucks have a sufficient water supply during firefighting operations, providing strong support for the smooth progress of firefighting work, and thus minimizing the loss of life and property caused by fires.

[0003] In the prior art, Chinese patent application number CN202420456529.3 discloses a water-saving fire hydrant, including a collection box. The fire hydrant body is located on the top right side of the collection box, and a fixed flange and an inlet pipe are connected to the bottom of the fire hydrant body. A filter box is fixedly connected to the bottom left side of the collection box. This invention uses a motor to rotate a threaded rod, which in turn moves a threaded sleeve, which in turn moves a connecting block, which in turn moves a cover plate. This opens the collection box, allowing rainwater to be collected during rainy weather. The rainwater passes through the collection cover and enters the filter box, where it is filtered before entering the fire hydrant's piping. This improves water conservation and effectively solves the problem of traditional fire hydrants lacking rainwater collection capabilities, resulting in poor water-saving performance and reduced effectiveness.

[0004] Based on the above information, it is clear that existing technologies are typically installed outdoors, which may lead to accidental opening of fire hydrants, resulting in resource waste and even seriously affecting fire safety. Therefore, we propose a fire sprinkler hydrant designed to prevent accidental opening. Utility Model Content

[0007] The anti-misoperation mechanism includes a mounting block fixedly installed on the top of the fire hydrant body, and a compression plate slidably installed on the inner wall of the mounting block and slidably connected to the valve stem. A compression spring is provided on the outer wall of the compression plate, and a slider is fixedly installed on the outer wall of the compression plate. A limiting plate with its bottom abutting against the outer wall of the compression plate is slidably installed on the outer wall of the valve stem end, and a handle slidably connected to the outer wall of the mounting block is fixedly installed on the outer wall of the limiting plate. A limiting block is fixedly installed on the outer wall of the limiting plate, and a storage mechanism for storing the rotating disc is provided on the outer wall of the fire hydrant body.

[0008] Furthermore, the limiting plate is designed in a circular shape, and the outer wall of the top of the limiting plate is in contact with the outer wall of the bottom of the valve stem nut. The extrusion plate is correspondingly provided with the limiting plate.

[0009] Furthermore, the limiting block has an arc-shaped cross-section, and multiple sets of limiting blocks are arranged at equal angles on the top of the limiting plate. Multiple sets of limiting slots corresponding to the limiting blocks are opened on the bottom outer wall of the valve stem nut.

[0010] Furthermore, two sets of handles are symmetrically arranged on the outer wall of the limiting plate, and the length of the handle is greater than the distance between the outer wall of the limiting plate and the outer wall of the mounting block. The outer wall of the mounting block is provided with a limiting groove, and the cross-section of the limiting groove is L-shaped. The outer wall of the handle is in contact with the outer wall of the limiting groove.

[0011] Furthermore, the slider is provided in multiple sets at equal angles on the outer wall of the extrusion plate, and the inner wall of the mounting block is provided with a sliding groove corresponding to the slider. The extrusion spring is provided in multiple sets at equal angles on the bottom of the extrusion plate, and one end of the extrusion spring is in contact with the outer wall of the extrusion plate, and the other end is in contact with the top outer wall of the fire hydrant body.

[0012] Furthermore, the storage mechanism includes a placement block fixedly installed on the outer wall of the fire hydrant body, and the outer wall of the placement block has a placement groove corresponding to the end of the rotating disk. A sliding rod is slidably installed on the outer wall of the placement block, and a locking block is slidably installed at the end of the sliding rod. A return spring is sleeved on the outer wall of the sliding rod.

[0013] Furthermore, the placement block is located on the side wall of the fire hydrant body, and the outer diameter of the placement block is larger than the outer diameter of the end of the rotating disk.

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

[0017] This fire sprinkler hydrant, designed to prevent accidental opening, features a limit plate and a limit block on the bottom outer wall of the valve stem nut. When the valve stem nut is closed, the limit block engages with a limit groove on the bottom outer wall of the valve stem nut, preventing it from rotating and thus preventing accidental opening of the hydrant. This avoids resource waste and fire safety issues. During use, manually squeezing and rotating the limit plate disengages the limit block from the limit groove on the outer wall of the valve stem nut, allowing the rotating disc to turn the valve stem nut. This ensures that the fire hydrant prevents accidental opening without affecting normal use.

[0018] Furthermore, by providing a placement block on the outer wall of the fire hydrant body, after the rotating disc is used, simply insert the end of the rotating disc into the placement groove opened on the outer wall of the placement block, and the locking block will enter the slot on the outer wall of the rotating disc, thus achieving convenient storage of the rotating disc. When taking it out, simply pull the sliding rod manually to make the locking block disengage from the slot, thus achieving convenient storage of the rotating disc and convenient access to the rotating disc at any time.

[0027] 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.

[0028] Example 1: Please refer to Figure 1-7This utility model provides the following technical solution: a fire sprinkler hydrant to prevent accidental opening, comprising a fire hydrant body 1, a valve stem 3 inside the fire hydrant body 1, and a valve stem nut 4 fixedly installed at the top of the valve stem 3, and a rotating disk 5 movably connected to the outer wall of the valve stem nut 4, the outer wall of the end of the rotating disk 5 having a nut groove 501 corresponding to the valve stem nut 4, the top of the fire hydrant body 1 having an anti-accidental opening mechanism, the anti-accidental opening mechanism including an installation block 2 fixedly installed at the top of the fire hydrant body 1, and a compression plate 7 slidably installed on the inner wall of the installation block 2 and slidably connected to the valve stem 3, and a compression spring 701 on the outer wall of the compression plate 7, a slider 702 fixedly installed on the outer wall of the compression plate 7, a limiting plate 6 slidably installed on the outer wall of the end of the valve stem 3 with its bottom abutting against the outer wall of the compression plate 7, and a handle 601 fixedly installed on the outer wall of the limiting plate 6 and slidably connected to the outer wall of the installation block 2, and a limiting block 602 fixedly installed on the outer wall of the limiting plate 6, the limiting plate 6 having an overall circular design, and limiting... The top outer wall of the positioning plate 6 fits against the bottom outer wall of the valve stem nut 4. The extrusion plate 7 is correspondingly set with the limiting plate 6. The limiting block 602 has an arc-shaped cross-section, and multiple sets of limiting blocks 602 are set at equal angles on the top of the limiting plate 6. Multiple sets of limiting slots 401 corresponding to the limiting blocks 602 are opened on the bottom outer wall of the valve stem nut 4. Two sets of handles 601 are symmetrically set on the outer wall of the limiting plate 6, and the length of the handles 601 is greater than the distance between the outer wall of the limiting plate 6 and the outer wall of the mounting block 2. The wall has a limiting groove 201 with an L-shaped cross section. The outer wall of the handle 601 is in contact with the outer wall of the limiting groove 201. Multiple sets of sliders 702 are set at equal angles on the outer wall of the extrusion plate 7. The inner wall of the mounting block 2 has a sliding groove 202 corresponding to the slider 702. Multiple sets of compression springs 701 are set at equal angles at the bottom of the extrusion plate 7. One end of the compression spring 701 is in contact with the outer wall of the extrusion plate 7, and the other end is in contact with the top outer wall of the fire hydrant body 1.

[0029] When the valve stem nut 4 is in the closed state, the limiting block 602 enters the limiting groove 401 opened on the bottom outer wall of the valve stem nut 4, limiting the valve stem nut 4 and preventing it from rotating. This prevents the fire hydrant body 1 from being opened incorrectly, avoiding resource waste and fire safety issues. When the fire hydrant body 1 needs to be used, first manually press the handle 601. The handle 601 drives the limiting plate 6 and the limiting block 602 to slide downwards along the outer wall of the valve stem 3. At the same time, the limiting plate 6 squeezes the compression plate 7 and the compression spring 701 until the handle 601 slides along the limiting groove 201 until it can no longer slide. Rotating the handle 601 along the limiting slide groove 201 causes the limiting block 602 to disengage from the limiting groove 401 on the outer wall of the valve stem nut 4, thus enabling the rotating disk 5 to tighten the valve stem nut 4. Then, rotating the rotating disk 5 around the outer wall of the valve stem nut 4 opens the fire hydrant body 1, thereby preventing accidental opening of the fire hydrant body 1 without affecting normal use. After closing the fire hydrant body 1, rotating the handle 601, under the action of the compression plate 7 and the compression spring 701, causes the limiting block 602 to re-enter the limiting groove 401 on the outer wall of the valve stem nut 4 to re-limit the valve stem nut 4.

[0030] Example 2: Based on Example 1, a storage mechanism is also disclosed, the specific structure of which is as follows: The outer wall of the fire hydrant body 1 is provided with a storage mechanism for storing the rotating disk 5. The storage mechanism includes a placement block 8 fixedly installed on the outer wall of the fire hydrant body 1, and the outer wall of the placement block 8 is provided with a placement groove 801 corresponding to the end of the rotating disk 5. A sliding rod 901 is slidably installed on the outer wall of the placement block 8, and a locking block 9 is slidably installed at the end of the sliding rod 901. A return spring 902 is sleeved on the outer wall of the sliding rod 901. The placement block 8 is located on the side wall of the fire hydrant body 1, and the outer diameter of the placement block 8 is larger than the outer diameter of the end of the rotating disk 5. The corner of the locking block 9 close to the rotating disk 5 is designed at an angle, and the outer wall of the rotating disk 5 is provided with a slot 502 corresponding to the locking block 9. The cross section of the sliding rod 901 is designed in a T shape. One end of the return spring 902 is in contact with the outer wall of the sliding rod 901, and the other end of the return spring 902 is in contact with the inside of the placement block 8.

[0031] By providing a placement block 8 on the outer wall of the fire hydrant body 1, after the rotating disc 5 is used, simply insert the end of the rotating disc 5 into the placement groove 801 opened on the outer wall of the placement block 8, and the locking block 9 enters the slot 502 on the outer wall of the rotating disc 5 to achieve convenient storage of the rotating disc 5. When taking it out, simply pull the slide bar 901 manually to make the locking block 9 disengage from the slot 502, thus achieving convenient storage of the rotating disc 5 and convenient access to the rotating disc 5 at any time.
