Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire hydrant technology, specifically a fire hydrant device for fire early warning. Background Technology
[0002] Outdoor fire hydrants are water supply facilities installed on the fire water supply network outside buildings. They primarily allow fire trucks to draw water from the municipal water supply network or the outdoor fire water supply network for firefighting. They can also be directly connected to fire hoses and nozzles for firefighting, making them one of the most important fire-fighting facilities. Outdoor fire water supply pipelines can use high-pressure, temporary high-pressure, and low-pressure pipelines. Outdoor fire water supply in towns, residential areas, and enterprises generally uses low-pressure water supply systems, and is often combined with domestic and industrial water supply pipelines. However, high-pressure or temporary high-pressure water supply pipelines should be separated from industrial and domestic water supply pipelines and installed as independent fire water supply pipelines to ensure water supply safety.
[0003] A search revealed that in a fire hydrant for fire early warning, patent publication number CN215829530U states that "in this utility model, a protective plate, sleeve, movable rod, and spring are used to protect the fire hydrant body. In the event of a collision, the deformation of the spring and the protective plate provides a buffering effect."
[0004] However, the above solution still has some shortcomings in actual use. The technical solution uses a protective plate to protect the fire hydrant body, but the protective plate is only located on the lower half of the fire hydrant body, so the protective effect of the protective plate cannot cover other parts of the fire hydrant body, resulting in a significant reduction in the protective effect of the fire hydrant body. Utility Model Content
[0005] This utility model provides a fire hydrant device for fire early warning, in order to solve the problems in the background art.

[0007] The drive mechanism includes a fixed frame, an electro-hydraulic push rod is fixedly installed on the inner wall of the fixed frame, a connecting rod is fixedly installed on the movable end of the electro-hydraulic push rod, and a lifting frame is installed on the other end of the connecting rod.
[0008] The buffer structure includes a buffer box, inside which a damping spring rod is fixedly connected. Two movable blocks are slidably connected to the surface of the damping spring rod. A cross frame is movably connected between the two movable blocks. A hinge rod is rotatably connected to one end of the cross frame away from the movable blocks. A buffer plate is fixedly connected to the other end of the hinge rod. The buffer plate is located on the outside of the buffer box.
[0009] Furthermore, the fire hydrant body includes a hydrant body, the bottom end of which is in contact with the ground via a fixing pin, and a water outlet valve is provided on the surface of the hydrant body.
[0010] Furthermore, the maximum height of the fixed frame and the lifting frame is greater than the height of the fire hydrant body.
[0011] Furthermore, the outer side of the fixed frame is provided with an insertion opening, the size of which is adapted to the specifications of the buffer box.
[0012] Furthermore, the bent portion of the connecting rod is fixedly connected to the interior of the lifting frame, and the length of the bent portion of the connecting rod is greater than the length of the buffer mechanism extending to the outside of the insertion opening.
[0013] Furthermore, the surface of the buffer box has a through opening, through which the hinge rod extends to the outside of the buffer box.
[0014] Compared with the prior art, this utility model provides a fire hydrant device for fire early warning, which has the following beneficial effects:
[0015] This fire hydrant device for fire early warning uses a drive mechanism and an electric hydraulic push rod inside the fixed frame to control the lifting frame via a connecting rod, enabling height adjustment.

[0021] 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.
[0022] Please see Figure 1-4 This utility model discloses a fire hydrant device for fire early warning, including a fire hydrant body 1, a drive mechanism 2 provided on the outside of the fire hydrant body 1, and a buffer structure 3 provided on the outside of the drive mechanism 2.
[0023] The fire hydrant body 1 includes a hydrant body 101, the bottom end of which is in contact with the ground via a fixing pin 102, and a water outlet valve 103 is provided on the surface of the hydrant body 101.
[0024] The drive mechanism 2 includes a fixed frame 201, an electro-hydraulic push rod 202 is fixedly installed on the inner wall of the fixed frame 201, a connecting rod 203 is fixedly installed on the movable end of the electro-hydraulic push rod 202, and a lifting frame 204 is installed on the other end of the connecting rod 203.
[0025] By setting up a drive mechanism 2, the electric hydraulic push rod 202 inside the fixed frame 201 can be used to control the lifting frame 204 through the connecting rod 203 to achieve the height adjustment function. This allows the total height of the fixed frame 201 and the lifting frame 204 to be flexibly adjusted according to the actual usage needs and idle status of the fire hydrant body 1. This not only ensures the convenience of the fire hydrant during use, but also guarantees safety protection in the non-use state, thereby achieving a comprehensive protection effect.
[0026] The buffer structure 3 includes a buffer box 301. A damping spring rod 302 is fixedly connected inside the buffer box 301. Two movable blocks 303 are slidably connected to the surface of the damping spring rod 302. A cross bracket 304 is movably connected between the two movable blocks 303. A hinge rod 305 is rotatably connected to one end of the cross bracket 304 away from the movable blocks 303. A through opening is provided on the surface of the buffer box 301. The hinge rod 305 extends to the outside of the buffer box 301 through the through opening. A buffer plate 306 is fixedly connected to the other end of the hinge rod 305. The buffer plate 306 is located on the outside of the buffer box 301.
[0027] By setting up the buffer structure 3, when the fire hydrant device is subjected to external impact, such as a vehicle collision, the buffer plate 306 is the first to bear the force. The force is then transmitted to the cross bracket 304 via the hinge rod 305. The cross bracket 304 then pushes the two movable blocks 303 to slide on the damping spring rod 302. At this time, the damping spring rod 302 plays a role in buffering and absorbing energy, effectively reducing the impact of external forces on the fire hydrant device and protecting the fire hydrant body 1 from damage.
[0028] Specifically, the maximum height of the fixed frame 201 and the lifting frame 204 is greater than the height of the fire hydrant body 1.
[0029] In this embodiment, the fixed frame 201 and the lifting frame 204 can cover the fire hydrant body 1, thereby achieving the effect of all-round protection.
[0030] Specifically, the fixed frame 201 has an insertion opening 205 on its outer side, and the size of the insertion opening 205 is adapted to the specifications of the buffer box 301.
[0031] In this embodiment, the buffer box 301 can be assembled using the insertion port 205, so that the buffer box 301 is stably installed on the outside of the fixed frame 201, thus preventing the buffer box 301 from falling off during use.
[0032] Specifically, the bent part of the connecting rod 203 is fixedly connected to the inside of the lifting frame 204, and the length of the bent part of the connecting rod 203 is greater than the length of the buffer mechanism extending to the outside of the insertion port 205.
[0033] In this embodiment, the bending design of the connecting rod 203 not only enhances the structural stability but also ensures the stability of the lifting frame 204 during height adjustment. When the electro-hydraulic push rod 202 operates, the bend in the connecting rod 203, as a key connection point, effectively transmits force, enabling the lifting frame 204 to smoothly and accurately reach the required height. Simultaneously, this design prevents interference between the buffer structure 3 and the connecting rod 203 during lifting, ensuring smooth operation of the entire device. This allows the lifting frame 204 to descend smoothly to the height of the fixed frame 201, enabling the lifting frame 204 to fit over the outside of the fixed frame 201.
[0034] When the fire hydrant body 1 needs to be used, the electric hydraulic push rod 202 is activated. The movable end of the electric hydraulic push rod 202 pushes the connecting rod 203, and the connecting rod 203 drives the lifting frame 204 to descend until the lifting frame 204 is fitted on the outside of the fixed frame 201. At this time, the fire hydrant body 1 is fully exposed, making it convenient for personnel to operate the water outlet valve 103 to draw water.
[0035] After the fire hydrant body 1 is used up, the electric hydraulic push rod 202 is activated again. The movable end of the electric hydraulic push rod 202 drives the connecting rod 203 to rise, and the connecting rod 203 drives the lifting frame 204 to move up until the total height of the lifting frame 204 and the fixed frame 201 completely covers the fire hydrant body 1, which plays a good protective role for the fire hydrant body 1 and avoids damage to the fire hydrant body 1 when it is not in use.
[0036] When the buffer plate 306 is impacted, the buffer plate 306 will cause the hinge rod 305 to move. Under the action of the hinge rod 305 and with the cooperation of the cross frame 304, the movable block 303 can move towards the spring, thereby compressing the spring. Through the continuous extension and contraction of the spring, the impact is buffered to avoid serious damage to the drive mechanism 2, thereby reducing the risk of damage to the fire hydrant body 1.
[0037] In summary, this fire hydrant device for fire early warning, by setting up a drive mechanism 2 and utilizing the electric hydraulic push rod 202 inside the fixed frame 201, can control the lifting frame 204 through the connecting rod 203 to achieve height adjustment. This allows the total height of the fixed frame 201 and the lifting frame 204 to be flexibly adjusted according to the actual usage needs of the fire hydrant body 1 and its idle state. This not only ensures the convenience of the fire hydrant during use but also guarantees safety protection when not in use, thus achieving a comprehensive protective effect.
[0038] It should be noted that the specific model and specifications of the electric hydraulic push rod 202 in the fire hydrant device for fire early warning need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.
[0039] Furthermore, the power supply and principle of the electro-hydraulic actuator 202 in the fire hydrant device for fire early warning are clear to those skilled in the art, and will not be described in detail here.
[0040] 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.
