Description

Technical Field

[0001] This utility model relates to the field of forest and grassland fire prevention technology, specifically to an automatic sprinkler system for forest and grassland firebreaks. Background Technology

[0002] Forest and grassland firebreaks are important fire barriers, and sprinkler systems play a crucial role in them. Through proper moisture distribution, they reduce the flammability of vegetation and can respond quickly in the event of a fire, creating a moist area to help prevent the spread of fire and protect the ecological security of forests and grasslands.

[0003] Utility model patent CN215461604U discloses a fire-prevention sprinkler device. This device includes a main body, several sprinkler components, and connectors for connecting the sprinkler components. Each sprinkler component includes a water pipe, sprinkler elements positioned above the water pipe, and threaded sleeves at both ends of the water pipe. This device effectively prevents fires during construction by installing multiple sets of sprinkler components in the absorption tower. It allows for the connection of sprinkler components of different lengths according to different construction scenarios, meeting construction needs and applicable to most situations. Furthermore, it is easy to disassemble and assemble, improving work efficiency.

[0004] The sprinkler system, which is suitable for fire prevention, has its sprinkler components directly exposed to the outside. When used in firebreaks in forest and grassland outdoor environments, it is easily damaged or blocked by wind, sun, sand and dust, or animal contact, which affects the normal functioning of the sprinkler system. In addition, it lacks protective design for complex outdoor environments. Therefore, we propose an automatic sprinkler system for forest and grassland firebreaks. Utility Model Content

[0005] The purpose of this invention is to provide an automatic sprinkler system for forest and grassland firebreaks, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic sprinkler system for forest and grassland firebreaks includes a sprinkler mechanism. The sprinkler mechanism includes a base and a vertical pipe erected on the top of the base. Several nozzles are installed on the outer periphery of the top of the vertical pipe. A guide sleeve is fitted around the bottom periphery of the vertical pipe. A movable sleeve is fitted over the guide sleeve and can move along the axial direction of the vertical pipe. An opening and closing mechanism is provided on the base. The opening and closing mechanism includes a fixed seat fitted on the outside of the guide sleeve and several gears rotatably connected to the top of the fixed seat. Several tooth grooves are formed on the outer surface of the movable sleeve, and the gears mesh with the tooth grooves.

[0008] Preferably, a water inlet pipe is connected to the front end of the base, and the water inlet pipe is connected to the bottom end of the riser.

[0009] In this setup, the inlet pipe can introduce an external water source into the riser, providing a water flow channel for the sprinkler heads to spray water.

[0010] Preferably, an end plate is fixed to the top of the riser, and a temperature sensor is installed on the top of the end plate;

[0011] In this setup, the end plate restricts the range of motion of the movable sleeve, and the temperature sensor monitors the ambient temperature to trigger the device to operate.

[0012] Preferably, a plurality of vertical mounting grooves are formed on the outer peripheral surface of the guide sleeve with the axis of the guide sleeve as the center, and a plurality of rollers are rotatably connected in the mounting grooves, the rollers abutting against the inner wall of the movable sleeve;

[0013] In this setting, the mounting slot provides a mounting position for the rollers, which can reduce friction when the movable sleeve moves, making its movement smoother.

[0014] Preferably, the movable sleeve has a tubular structure, and the outer diameter of the movable sleeve is smaller than the outer diameter of the end plate. When the movable sleeve moves upward, the movable sleeve will eventually abut against the end plate, at which time the nozzle is housed inside the movable sleeve.

[0015] In this setup, the size matching between the movable sleeve and the end plate allows for the storage of the nozzle, protecting it from external environmental influences.

[0016] Preferably, a cavity is provided at the middle position of the fixing seat, and the cavity houses the guide sleeve.

[0017] In this design, the cavity can accommodate the guide sleeve, providing protection for the guide sleeve and ensuring its stable installation.

[0018] Preferably, the gear is coaxially provided with a rotating shaft, and both ends of the rotating shaft are coaxially fixedly connected with bevel gears, two adjacent bevel gears mesh with each other, and one of the rotating shafts is coaxially connected to a motor;

[0019] In this setup, the motor drives the gears to rotate via a shaft and bevel gears, achieving synchronous operation of multiple gears.

[0020] Preferably, the rotating shaft is fitted with a support seat, the support seat is fixed to the top of the fixed seat, the top of the fixed seat is fitted with a seat plate, and the motor is mounted on the top of the seat plate;

[0021] In this configuration, the support base supports the rotating shaft, and the base plate provides a stable mounting foundation for the motor, ensuring stable operation of the components.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This automatic sprinkler system for forest and grassland firebreaks can move axially along the riser via a movable sleeve. When the system is not in operation, the movable sleeve moves upward and abuts against the end plate, retracting the sprinkler head into the sleeve and effectively protecting it. This reduces the impact of factors such as sand, sun, and animals in the forest and grassland outdoor environment on the sprinkler head, ensuring its normal operation when needed.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0035] Please see Figures 1-5 An automatic sprinkler system for forest and grassland firebreaks includes a sprinkler mechanism 100, which comprises a base 110 and a vertical pipe 120 erected on top of the base 110. The base 110 provides stable support for the entire system, ensuring that the system is not easily tipped over in the forest and grassland outdoor environment. Several nozzles 122 are installed on the outer periphery of the top of the vertical pipe 120. The nozzles 122 are used to spray water from the vertical pipe 120 to achieve sprinkler operation on the firebreak. A water inlet pipe 111 is connected to the front end of the base 110 and is connected to the bottom end of the vertical pipe 120. The water inlet pipe 111 serves to transport water, introducing external water into the vertical pipe 120. A water pump is connected to the other end of the water inlet pipe 111, and the input end of the water pump is connected to a water storage tank through a pipe. An end plate 121 is fixed to the top of the riser 120. The end plate 121 can limit the upward movement of the movable sleeve 200. A temperature sensor 1211 is installed at the top of the end plate 121. The temperature sensor 1211 can monitor the ambient temperature in real time and provide a temperature signal for the start-up of the device. The temperature sensor 1211 is electrically connected to the water pump, so that the temperature sensor 1211 can control the start and stop of the water pump according to the monitored temperature.

[0036] like Figure 2 and Figure 3 As shown, in this utility model, a guide sleeve 130 is fitted around the bottom periphery of the riser 120. The guide sleeve 130 provides guidance for the movement of the movable sleeve 200, ensuring that the movable sleeve 200 moves stably along the axial direction of the riser 120. The movable sleeve 200 is fitted over the guide sleeve 130, and the movable sleeve 200 can move outside the guide sleeve 130 to store and protect the nozzle 122 when not in use. The outer circumferential surface of the guide sleeve 130 is oriented with the guide sleeve 130 axis. A number of vertical mounting grooves 131 are provided around the line, and the mounting grooves 131 provide mounting space for the rollers 132. A number of rollers 132 are rotatably connected in the mounting grooves 131. The rollers 132 abut against the inner wall of the movable sleeve 200, which can reduce the friction between the movable sleeve 200 and the guide sleeve 130 when the movable sleeve 200 moves, so that the movable sleeve 200 moves more smoothly. The rollers 132 abut against the inner wall of the movable sleeve 200, and the movable sleeve 200 can move along the axial direction of the riser 120.

[0037] like Figure 1 , Figure 2 and Figure 4As shown, specifically, the movable sleeve 200 has a tubular structure, and the outer diameter of the movable sleeve 200 is smaller than the outer diameter of the end plate 121. When the movable sleeve 200 moves upward, it will eventually abut against the end plate 121. At this time, the nozzle 122 is stored inside the movable sleeve 200. This design can prevent the nozzle 122 from being exposed when not in operation, and reduce the impact of sand, sun exposure, animals and other factors on the nozzle 122 in the outdoor environment of forests and grasslands.

[0038] like Figure 1 and Figure 5 As shown, the base 110 is further provided with an opening and closing mechanism 300, which is used to drive the movable sleeve 200 to move, so as to realize the storage and exposure of the nozzle 122. The opening and closing mechanism 300 includes a fixed seat 310 sleeved on the outside of the guide sleeve 130 and several gears 320 rotatably connected to the top of the fixed seat 310. The fixed seat 310 provides a mounting and support base for the gears 320 and other components. A cavity 311 is opened in the middle of the fixed seat 310. The cavity 311 covers the guide sleeve 130 and provides a space for the guide sleeve 130, while also providing a certain degree of protection for the guide sleeve 130. Several toothed grooves 210 are opened on the outer surface of the movable sleeve 200. The gears 320 mesh with the toothed grooves 210. When the gears 320 rotate, they drive the movable sleeve 200 to move axially through meshing with the toothed grooves 210.

[0039] like Figure 5 As shown, in addition, a rotating shaft 321 is coaxially mounted on the gear 320. The rotating shaft 321 is used to install and fix the gear 320 and drive the gear 320 to rotate. Both ends of the rotating shaft 321 are coaxially fixedly connected to bevel gears 322. Adjacent bevel gears 322 mesh with each other. The meshing of the bevel gears 322 enables the transmission and steering of power, allowing multiple gears 320 to rotate synchronously. One of the rotating shafts 321 is coaxially connected to a motor 330, which provides power for the operation of the entire opening and closing mechanism 300. A support seat 323 is fitted around the rotating shaft 321, which supports the rotating shaft 321 and ensures stable rotation. The support seat 323 is fixed to the top of the fixed seat 310, and a base plate is installed on the top of the fixed seat 310. The base plate provides an installation position for the motor 330, ensuring that the motor 330 is installed securely. The motor 330 is installed on the top of the base plate. The motor 330 is electrically connected to the temperature sensor 1211. When the temperature sensor 1211 detects a preset threshold, the motor 330 starts and drives the gear 320 to rotate.

[0040] In addition, it is worth noting that a protective cover 400 is fitted on the top of the opening and closing mechanism 300. The protective cover 400 covers the gear 320 and motor 330 located on the top of the fixed base 310. The movable sleeve 200 passes through the protective cover 400. The protective cover 400 can prevent sand, rain and other outdoor elements such as forests and grasslands from entering the gear 320 and motor 330, reduce the corrosion of these components by the external environment, maintain their normal working condition, and at the same time prevent debris from getting into the gear meshing and affecting the operation.

[0041] It is worth noting that the temperature sensor 1211 and the motor 330 involved in this utility model are both existing conventional technologies, and will not be described in detail here.

[0042] In this embodiment, the automatic sprinkler system for forest and grassland firebreaks operates as follows: First, the temperature sensor 1211 monitors the ambient temperature in real time. Then, when the temperature sensor 1211 detects that the temperature has reached a preset threshold, it sends a signal to the motor 330 and the water pump. Next, the motor 330 starts, driving the gear 320 to rotate via the shaft 321 and bevel gear 322. The gear 320 meshes with the toothed groove 210 on the movable sleeve 200, causing the movable sleeve 200 to move downwards, and the nozzle 122 to protrude from inside the movable sleeve 200. Simultaneously, the water pump starts, transporting water from the storage tank to the riser 120 through the inlet pipe 111, and then spraying it out through the nozzle 122 for spraying. Finally, when the ambient temperature drops below the preset threshold, the temperature sensor 1211 sends a signal, the water pump stops working, the motor 330 reverses, driving the movable sleeve 200 to move upwards until it abuts against the end plate 121, the nozzle 122 retracts into the movable sleeve 200, and the motor 330 stops working.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
