Description

Technical Field

[0001] The present application relates to the field of fire extinguishing devices, and in particular to an automatic water sprinkler fire extinguishing device. Background Art

[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine the coal. After mining, the coal is generally transported out of the underground by conveyors.

[0003] Conveyors are the primary transport equipment for coal in coal mines. During this process, slippage and friction between the belts and the coal, as well as friction between the coal itself, can easily cause the coal to heat up, making it highly susceptible to fires. Traditional fire extinguishing systems for conveyors in coal mines use smoke or temperature sensors to monitor the environment. Upon detecting smoke or high temperatures, nozzles located at the roof of the mine spray water toward the conveyor to reduce dust and extinguish fires.

[0004] Regarding the above-mentioned related technologies, when the nozzle is set at the top of the coal mine to spray water on the conveyor, due to the relatively high position of the nozzle, it is difficult to directly spray effectively at the root of the fire point, thereby limiting its fire extinguishing effect and making it difficult to achieve precise control of the fire. Utility Model Content

[0005] In order to improve the fire extinguishing effect, the present application provides an automatic water sprinkler fire extinguishing device.

[0006] The automatic sprinkler fire extinguishing device provided in this application adopts the following technical solution:

[0007] An automatic sprinkler fire extinguishing device includes a fire extinguishing assembly, the fire extinguishing assembly including a temperature sensor arranged at the bottom of a conveyor, a support frame arranged on one side of the conveyor, and a support rod arranged on the support frame, the support rod being erected above the conveyor through the support frame; a nozzle is arranged at the bottom of the support rod, the nozzle is used to spray a fire extinguishing medium onto the fire point on the conveyor, the nozzle is connected to a switch assembly, and the temperature sensor can control the nozzle switch through the switch assembly.

[0008] By adopting the above technical solution, when the temperature sensor detects a high temperature, the switch assembly controls the sprinkler to perform a spraying action. Since the sprinkler is located above the conveyor, it is closer to the fire point than the traditional sprinkler located on the mine roof and closer to the root of the fire point, thereby achieving effective spraying of the fire point and improving the fire extinguishing efficiency.

[0009] Optionally, one end of the support rod is rotatably connected to the support frame, and the other end can be rotated toward or away from the support frame; when the support rod is rotated toward and away from the support frame, it is installed above the conveyor.

[0010] By adopting the above technical solution, through the rotation connection of the support rod, under normal conditions, the support rod can be rotated to the side close to the support frame, which not only facilitates storage and improves space utilization, but also facilitates workers' loading operations on the conveyor during the transmission process.

[0011] Optionally, the support frame is provided with a receiving groove, and the support rod is rotatably connected to the support frame in the receiving groove. When the support rod rotates toward a side close to the support frame, the support rod is located in the receiving groove.

[0012] By adopting the above technical solution, the opening of the receiving groove enables the support rod to be accommodated in the mounting frame, reducing the space occupied by the support rod. At the same time, the abutment between the nozzle and the groove wall can reduce the possibility of dust entering the nozzle.

[0013] Optionally, a delivery pipe 1 for delivering fire extinguishing medium is provided in the support frame, and a delivery pipe 2 is provided in the support rod along its own length direction. The delivery pipe 2 is connected to the nozzle, and the other end is used to be connected to the delivery pipe 1; the switch assembly controls the nozzle switch by controlling the connection between the delivery pipe 1 and the delivery pipe 2.

[0014] By adopting the above technical solution, the effective delivery of fire extinguishing medium is achieved through the cooperation of delivery pipe 1 and delivery pipe 2. At the same time, the switch control of the nozzle is achieved by controlling the connection between delivery pipe 1 and delivery pipe 2. The structure of the switch component is simple and reliable, which reduces the use of electric control valves and reduces the cost of the fire extinguishing device.

[0015] Optionally, the switch assembly includes a connecting block that is slidingly connected to the delivery pipe 1, one end of the connecting block is an open end, the other end is a sealed end, and a connecting port is provided on the side wall of the connecting block; the sealed end of the connecting block is located inside the delivery pipe 1, and the other end is used to be connected to the delivery pipe 2. When the support rod rotates away from the support frame, the support rod drives the connecting block to slide into the inside of the delivery pipe 1, so that the delivery pipe 1 is connected to the delivery pipe 2 through the connecting port.

[0016] By adopting the above technical solution, the connection between the connecting port and the delivery pipe 1 is controlled by sliding the connecting block, thereby achieving effective connection between the delivery pipe 1 and the delivery pipe 2, and then achieving connection between the delivery pipe 1 and the delivery pipe 2, thereby controlling the switch of the nozzle.

[0017] Optionally, the support frame is provided with an electric push rod for driving the support rod to rotate, and the electric push rod is provided with a push rod, the push rod is hinged to the support rod, and the end of the push rod is slidingly connected to the support rod.

[0018] By adopting the above technical solution, the setting of the electric push rod and the push rod facilitates the automatic rotation of the support rod. By electrically connecting the electric push rod with the temperature sensor, the fire extinguishing component can be automatically started when the temperature rises, further improving the convenience of use.

[0019] Optionally, the temperature sensor is electrically connected to a controller and outputs the detected temperature to the controller. The controller is connected to the electric push rod. The controller has a preset threshold temperature and receives the detected temperature. When the detected temperature is greater than the threshold temperature, the controller drives the electric push rod to operate.

[0020] By adopting the above technical solution, through the setting of the controller and the threshold temperature, automatic temperature detection and timely activation of the fire extinguishing device can be achieved, thereby improving the fire extinguishing efficiency.

[0021] Optionally, there are multiple fire extinguishing components, and the multiple fire extinguishing components are arranged along the length direction of the conveyor. The temperature sensor in each fire extinguishing component is also electrically connected to the controller in the connected fire extinguishing component. When any received detection temperature is greater than the threshold temperature, the controller drives the electric push rod connected to it to operate.

[0022] By adopting this technical solution, when any temperature sensor detects an abnormal temperature, it can trigger the adjacent fire extinguishing components to perform a coordinated fire extinguishing operation, thereby expanding the fire extinguishing range and improving the overall fire extinguishing effect. When the fire is transported away from the conveyor and the temperature detected by the temperature sensor drops, the electric actuator drives the support rod to rotate toward the support frame, simultaneously disconnecting the connection between the first and second conveying pipes, and thus closing the fire extinguishing components.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The present invention uses a temperature sensor installed at the bottom of the conveyor and a nozzle on the support frame to achieve accurate detection of the fire point and effective spraying. This overcomes the disadvantage of traditional fire extinguishing devices that make it difficult to spray directly at the root of the fire due to the high position of the nozzle, significantly improving the fire extinguishing effect and accuracy.

[0025] 2. Through the controller and the preset threshold temperature, the fire extinguishing device can be automatically activated at the first fire, timely controlling the fire and preventing the fire from spreading, greatly reducing the losses caused by the fire;

[0026] 3. Set up multiple fire extinguishing components to extinguish fires in conjunction. When any temperature sensor detects a temperature abnormality, it can trigger the adjacent fire extinguishing components to perform a coordinated fire extinguishing operation, thereby expanding the fire extinguishing range and improving the overall fire extinguishing effect.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] In this application, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; and internal communication between two components or interaction between two components.

[0035] In this application, unless otherwise expressly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0036] The embodiment of the present application discloses an automatic sprinkler fire extinguishing device. Figure 1 An automatic sprinkler fire extinguishing device includes a plurality of fire extinguishing components 11, and the plurality of fire extinguishing components 11 are evenly arranged along the length direction of the conveyor 1. Each fire extinguishing component 11 includes a temperature sensor 6 installed at the bottom of the conveyor 1 and a support frame 2 fixed to one side of the conveyor 1. The support frame 2 is provided with a support rod 3, and the support rod 3 can be erected above the conveyor 1 through the support frame 2. A nozzle 4 is fixed to the bottom of the support rod 3. The nozzle 4 is used to spray the fire extinguishing medium to the fire point on the conveyor 1. The nozzle 4 is connected to a switch component 5. The temperature sensor 6 can control the nozzle 4 to perform the spraying action through the switch component 5. When the temperature sensor 6 detects a high temperature, the switch component 5 controls the nozzle 4 to perform the spraying action. Since the nozzle 4 is located above the conveyor 1, it is closer to the fire point than the traditional nozzle 4 located on the mine roof, and closer to the root of the fire point, thereby achieving effective spraying of the fire point, thereby improving the fire extinguishing efficiency.

[0037] Specifically, refer to Figure 1 The support frame 2 is provided with a receiving groove 21, and the support rod 3 is rotatably connected to the support frame 2 in the receiving groove 21. One end of the support rod 3 is rotatably connected to the support frame 2, and the other end can be rotated toward or away from the support frame 2. Under normal conditions, the support rod 3 is located in the receiving groove 21 and is arranged parallel to the support frame 2, while the nozzle 4 abuts against the groove wall of the receiving groove 21. When a fire occurs, the support rod 3 is rotated away from the end connected to the support frame 2 and is mounted above the conveyor 1. The rotation setting of the support rod 3 allows the support rod 3 to be rotated to the side close to the support frame 2 under normal conditions, which is not only convenient for storage and storage, but also facilitates the workers' loading operations on the conveyor 1. The opening of the receiving groove 21 allows the support rod 3 to be stored in the mounting frame, reducing the space occupied by the support rod 3. At the same time, the abutment of the nozzle with the groove wall can reduce the possibility of dust entering the nozzle during normal times.

[0038] Reference Figure 2 and Figure 3A delivery pipe 1 22 for transporting fire extinguishing medium is fixedly connected to the support frame 2. A delivery pipe 2 31 is fixedly connected to the support rod 3 along its length. Delivery pipe 2 31 is connected to multiple nozzles 4. When the support rod 3 is erected above the conveyor 1, the end of delivery pipe 2 31 closest to delivery pipe 1 22 is connected to delivery pipe 1 22. A switch assembly 5 is located at the connection between delivery pipes 1 22 and 2 31. It controls the opening and closing of the nozzles 4 by controlling the connection between delivery pipes 1 22 and 2 31.

[0039] Reference Figure 3 The switch assembly 5 includes a connecting block 51 that is slidably connected to the delivery pipe 1 22. One end of the connecting block 51 is an open end, and the other end is a sealed end. A connecting port 52 is provided on the side wall of the connecting block 51. The sealed end of the connecting block 51 is located inside the delivery pipe 1 22, and the other end is used to connect to the delivery pipe 2 31. When the support rod 3 rotates away from the support frame 2, the support rod 3 abuts against the connecting block 51, driving the connecting block 51 to slide toward the inside of the delivery pipe 1 22, causing the connecting port 52 to slide into the delivery pipe 1 22. At the same time, the delivery pipe 1 22 is connected to the opening, thereby enabling the delivery pipe 1 22 to be connected to the delivery pipe 2 31 through the connecting port 52, thereby turning on the switch of the sprinkler 4 to perform a fire extinguishing operation. This structural design is simple, and the sprinkler 4 switch can be quickly turned on after the support rod 3 is rotated open.

[0040] Reference Figure 3 The connecting block 51 is fixedly connected with a return spring 53. Under normal conditions, the return spring 53 causes the connecting port 52 to be located outside the delivery pipe 22. When in the spraying state, the return spring 53 applies force to the connecting block 51 to move close to the delivery pipe 2 31. When the spraying is completed and the support rod 3 rotates toward the side close to the support frame 2, the connecting block 51 moves away from the delivery pipe 22 under the action of the return spring 53, automatically disconnecting the connecting port 52 from the delivery pipe 22.

[0041] Furthermore, a sealing ring (not shown in the figure) is fixedly connected at the connection position between the connecting block 51 and the delivery pipe 1 22 , and a sealing ring is also fixedly connected at the connection position between the connecting block 51 and the delivery pipe 2 31 , thereby sealing the delivery pipe.

[0042] Reference Figure 4 The support frame 2 is fixed with an electric push rod 7 for driving the support rod 3 to rotate near the connection position between the support frame 2 and the support rod 3. The electric push rod 7 is provided with a push rod 71, and the end of the push rod 71 is hinged with a slider 72. A slide groove 32 is provided on the upper side of the support rod 3, and the slide groove 32 is arranged along the length direction of the support rod 3. The slider 72 slides in the slide groove 32 along the length direction of the slide groove 32 to realize the sliding connection between the push rod 71 and the support rod 3. When the support rod 3 needs to be rotated, it is only necessary to start the electric push rod 7 to push the push rod 71 to move, thereby driving the support rod 3 to rotate around the rotating connection.

[0043] Furthermore, the nozzle 4 is umbrella-shaped, and the umbrella-shaped nozzle 4 can provide a wide spraying range, which can effectively cover a larger area, so that the spraying range can cover the entire width of the transport aircraft 1. Therefore, during the fire extinguishing process, the fire scene can be covered more quickly, thereby improving the fire extinguishing effect.

[0044] Furthermore, the temperature sensor 6 is fixed to the bottom of the conveyor 1 near the belt. The temperature sensor 6 is located at the bottom of the belt to detect the temperature. Due to the shielding of the belt, the influence of dust on the sensor during daily work can be reduced.

[0045] Reference Figure 5 Each temperature sensor 6 is electrically connected to a controller 61, which receives the detected temperature from the temperature sensor 6 and compares it with a preset threshold temperature. When the detected temperature exceeds the threshold, the controller 61 issues a command to the electric push rod 7, driving the connected electric push rod 7 to operate, thereby triggering the entire fire extinguishing process. Furthermore, the temperature sensor 6 in each fire extinguishing component 11 is electrically connected not only to its own controller 61 but also to the controller 61 in the adjacent fire extinguishing component 11. This way, when any temperature sensor 6 detects a temperature anomaly, it can trigger the adjacent fire extinguishing component 11 to perform a coordinated fire extinguishing operation, thereby expanding the fire extinguishing range and improving the overall fire extinguishing effect.

[0046] The implementation principle of an automatic sprinkler fire extinguishing device in an embodiment of the present application is as follows: after the temperature sensor 6 detects the fire point and sends a signal, the electric push rod 7 corresponding to the temperature sensor 6 and the adjacent electric push rod 7 will start together and push the support rod 3 to rotate above the conveyor 1. During the rotation of the support rod 3, the connecting block 51 will be squeezed, so that the connecting block 51 slides into the inside of the delivery pipe 1 22 under the drive of the support rod 3, thereby realizing the connection between the delivery pipe 1 22 and the delivery pipe 2 31. The fire extinguishing medium is then sprayed to the fire point through the nozzle 4 to perform the fire extinguishing operation. The whole process is fast and accurate, which significantly improves the fire extinguishing efficiency and safety. At the same time, the linkage control mechanism between multiple fire extinguishing components 11 further enhances the overall fire extinguishing capability, ensuring that the fire can be quickly and effectively controlled and prevented from spreading when a fire occurs.

[0047] The embodiments of the present application have the effect of improving the fire extinguishing effect.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
