Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing and water spraying, in particular to a fire extinguishing and water spraying device for identifying a fire source at a fixed point. Background Art

[0002] A fire refers to a disaster caused by combustion that gets out of control in terms of time or space. In the new standard, a fire is defined as combustion that gets out of control in terms of time or space. Fire is one of the main disasters that most frequently and commonly threaten public safety and social development.

[0003] However, in the prior art, fire sprinklers are usually of a fixed water spraying structure. This fixed water spraying method results in a limited water spraying coverage area, unable to effectively cover the entire fire area, thereby affecting the fire extinguishing efficiency and effect. In case of an unexpected fire, it requires multiple people to cooperate in operating a conventional fire hydrant hose for fire extinguishing, which is not suitable for operation and disposal in the case of a small number of people. Therefore, improvements are needed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the technical problems raised in the above background art.

[0005] The utility model adopts the following technical scheme: A fire extinguishing and water spraying device for identifying a fire source at a fixed point, including a water delivery pipe, a vertical pipe is rotatably connected to the surface of the water delivery pipe, a horizontal pipe is fixedly installed at the top end of the vertical pipe, a fire sprinkler is communicated with one end of the horizontal pipe, a large gear is fixedly installed on the surface of the vertical pipe, a torsion spring is sleeved on the surface of the vertical pipe, an impact rod is fixedly installed on the surface of the water delivery pipe, a mounting block is fixedly installed on the surface of the water delivery pipe, and a motor is fixedly installed on the top surface of the mounting block, and a semi-gear is installed at the output end of the motor.

[0006] Preferably, the semi-gear meshes with the large gear, and the water delivery pipe, the vertical pipe and the horizontal pipe are communicated with each other.

[0007] Preferably, one end of the torsion spring is fixedly connected to the water delivery pipe, and the other end of the torsion spring is communicated with the large gear. Here, the torsion spring can be stably installed.

[0008] Preferably, flanges are fixedly installed at both ends of the water delivery pipe, and the corners of the mounting block are provided with rounded corners.

[0009] Preferably, a filtering mechanism is arranged on the surface of the flange. The filtering mechanism includes a mounting groove opened on the surface of the flange, a mounting ring is placed on the inner wall of the mounting groove, a filter screen is fixedly installed on the inner side of the mounting ring, a plug rod is fixedly installed on the surface of the mounting ring, and a jack is opened on the inner wall of the mounting groove. Here, stains in the water can be filtered.

[0010] Preferably, the socket and the plug rod are of the same size.

[0011] Preferably, the number of the plug rods and the sockets is three groups each.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0013] 1. The present utility model can achieve automatic sprinkler fire extinguishing by connecting to a water source without manual operation, thereby improving the efficiency and timeliness of fire extinguishing. It is especially suitable for emergency situations such as fires in green plants and weeds. By installing it around the green plants, it can spray water at fixed points for the green plants and weeds. Moreover, through the meshing of the semi-gear and the large gear driven by the motor, the fire sprinkler can rotate counterclockwise and clockwise to form a fan-shaped water spraying range, ensuring the wide coverage of fire extinguishing. At the same time, when the fire sprinkler rotates counterclockwise and resets, it will collide with the impact rod and generate vibrations, which can further disperse the water flow and expand the water spraying range, thereby enhancing the fire extinguishing effect. The cyclic meshing and disengagement mechanism of the semi-gear and the large gear enables the fire sprinkler to repeatedly perform the water spraying action, ensuring continuous fire extinguishing and preventing the reignition of the fire.

[0014] 2. By setting a filter screen, the present utility model can effectively filter stains, reduce the entry of impurities into the fire sprinkler, and reduce the probability of the nozzle being blocked, thereby improving the reliability and service life of the water spraying device. At the same time, when the fire sprinkler resets and collides with the impact rod, the generated vibrations can be transmitted to the filter screen, causing the filter screen to vibrate, thereby automatically dredging the filter screen, preventing the filter screen from being blocked, and ensuring the smooth flow of water. The installation of the filter screen only requires aligning the installation ring outside the filter screen with the installation groove and buckling it in, and inserting the plug rod into the socket. The operation is simple and fast, without the need for complex tools, facilitating the maintenance and replacement of the filter screen. When the water delivery pipes are connected end to end through flanges, the installation rings will be mutually pressed and limited by the flanges, ensuring the stable fixation of the filter screen, preventing the filter screen from loosening or falling off during use, and enhancing the stability and reliability of the device. By reducing the probability of the nozzle being blocked and ensuring the dredging of the filter screen, it can ensure the stable water flow, maintain continuous and effective water spraying, improve the fire extinguishing efficiency, and ensure the smooth progress of the fire extinguishing process.

[0027] Embodiment 2

[0028] Please refer to Figures 3-5, a filtering mechanism is provided on the surface of the flange 11. The filtering mechanism includes an installation groove 12 which is opened on the surface of the flange 11. An installation ring 13 is placed on the inner wall of the installation groove 12. A filter screen 14 is fixedly installed inside the installation ring 13.

[0029] Working principle: The staff can lay the water delivery pipe 1 around the green plants, and then connect the water delivery pipes 1 end to end in sequence. If the green plants or weeds catch fire, only need to connect the water delivery pipe 1 to the water source, and then water can be sprayed through the fire sprinkler 4 for fire extinguishing. At the same time, the motor 9 can drive the semi-gear 10 to rotate clockwise, and then the semi-gear 10 can drive the large gear 5 meshed with it to rotate counterclockwise. The large gear 5 then drives the vertical pipe 2 to rotate counterclockwise, and the vertical pipe 2 then drives the horizontal pipe 3 to rotate. At this time, the fire sprinkler 4 can be rotated counterclockwise to spray water. Then when the semi-gear 10 disengages from the large gear 5, at this time due to the torsion of the torsion spring 6, the torsion spring 6 can drive the large gear 5 to rotate clockwise. The large gear 5 then drives the vertical pipe 2, the horizontal pipe 3 and the fire sprinkler 4 to rotate in sequence. At this time, the fire sprinkler 4 resets and collides with the impact rod 7, thereby forming a fan-shaped water spraying range. At the same time, the vibration generated by the collision can disperse the water flow of the fire sprinkler 4, thereby further increasing the water spraying range and improving the fire extinguishing effect. At the same time, the impact rod 7 limits the rotation angle of the impact rod 7, and then the semi-gear 10 then drives the large gear 5 to rotate counterclockwise again and repeats in sequence. The utility model can realize automatic water spraying and fire extinguishing by connecting to the water source without manual operation, thereby improving the efficiency and timeliness of fire extinguishing, and is particularly suitable for emergency situations such as green plants or weeds catching fire. And through the meshing of the motor 9 driving the semi-gear 10 and the large gear 5, the fire sprinkler 4 can be rotated counterclockwise and clockwise to form a fan-shaped water spraying range, ensuring the wide coverage of fire extinguishing. At the same time, when the fire sprinkler 4 rotates counterclockwise and resets, it will collide with the impact rod 7 and generate vibration, which can further disperse the water flow and expand the water spraying range, thereby enhancing the fire extinguishing effect. And the cyclic meshing and disengagement mechanism of the semi-gear 10 and the large gear 5 enables the fire sprinkler 4 to repeatedly perform the water spraying action, ensuring continuous fire extinguishing and preventing the fire from reigniting. And through the set filter screen 14, stains can be filtered, which can reduce the blockage probability of the fire sprinkler 4. At the same time, when the fire sprinkler 4 resets and collides with the impact rod 7, the generated vibration can make the filter screen 14 vibrate, thereby being able to dredge the filter screen 14. At the same time, when installing the filter screen 14, only need to align the mounting ring 13 outside the filter screen 14 with the mounting groove 12 and buckle it in, and let the insertion rod 15 insert into the jack 16. Then when the water delivery pipes 1 are installed end to end through the flange 11, the mounting ring 13 can be mutually pressed and limited by the flange 11. The utility model can effectively filter stains by setting the filter screen 14, reduce impurities from entering the fire sprinkler 4, reduce the probability of the nozzle being blocked, thereby improving the reliability and service life of the water spraying device. At the same time, when the fire sprinkler 4 resets and collides with the impact rod 7, the generated vibration can be transmitted to the filter screen 14, making the filter screen 14 vibrate, thereby automatically dredging the filter screen 14, preventing the filter screen 14 from being blocked, and ensuring smooth water flow. And the installation of the filter screen 14 only needs to align the mounting ring 13 outside the filter screen 14 with the mounting groove 12 and buckle it in, and let the insertion rod 15 insert into the jack 16, which is simple and fast to operate, does not require complex tools, and is convenient for maintaining and replacing the filter screen 14. And when the water delivery pipes 1 are connected end to end through the flange 11,The mounting ring 13 will be mutually squeezed and limited by the flange 11 to ensure the stable fixation of the filter screen 14, prevent the filter screen 14 from loosening or falling off during use, enhance the stability and reliability of the device, and by reducing the probability of nozzle blockage and ensuring the dredging of the filter screen 14, the water flow can be ensured to be stable, continuous and effective spraying can be maintained, the fire extinguishing efficiency can be improved, and the smooth progress of the fire extinguishing process can be ensured.
