Description

Technical Field

[0001] This utility model belongs to the field of fire emergency technology, specifically relating to an emergency fire extinguishing device for stacked straw stacks in agricultural greenhouses, waste paper / raw material straw stacks in paper mills, etc., which can realize the functions of early monitoring of fire inside the stack, rapid fire control and fire extinguishing by isolating air. Background Technology

[0002] In the paper industry, flammable materials such as raw paperboard must be bundled and stacked for storage. Due to poor internal ventilation, these stacks are prone to spontaneous combustion due to microbial fermentation and localized frictional heat. External open flames can also spread rapidly into the stacks, and if the fire gets out of control, it will cause significant economic losses.

[0003] The existing stacking fire extinguishing method has the following main drawbacks: Existing monitoring methods are mostly temperature sensors or smoke detectors on the outside of the stack, which cannot detect the signs of spontaneous combustion inside the stack (especially in the core area). They are often only discovered after the fire has broken through the surface of the stack, thus missing the opportunity to control the fire in the early stages. Fixed fire protection facilities (such as fire hydrants) are limited by their installation location and cannot cover the entire stacking area; fire trucks require professional personnel to operate and have a response time (usually several minutes to more than ten minutes), during which time the fire can easily spread; Therefore, there is an urgent need for an emergency fire extinguishing device to solve the problems of "late detection, slow fire control, and difficulty in isolation" in existing technologies. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a stack emergency fire extinguishing device to solve the technical problems of "difficulty in early detection of internal fires, slow fire extinguishing response, and untimely air isolation" in existing stack fire extinguishing systems, and to achieve early detection, early fire control, and rapid isolation of stack fires.

[0005] This utility model is achieved through the following technical solution: a stacked emergency fire extinguishing device, characterized in that it includes a detection rod assembly and a self-moving fire extinguishing cover assembly; The detection rod assembly includes a detection rod mounted on top and a fire extinguishing canister located outside the stack; a monitor is mounted on the detection rod, and a hollow cavity is provided inside the detection rod, which is connected to the external fire extinguishing canister through a pipeline; a spray hole connected to the cavity is also provided on the detection rod. The fire extinguishing hood assembly includes multiple retractable frames, which are U-shaped, and adjacent frames are connected by telescopic components; the fire extinguishing hood is set inside the frame structure composed of multiple frames, and multiple fixing rope loops are set on the fire extinguishing hood; an electric release device for connecting and cooperating with the fixing rope loops is fixed on the frame; and running wheels are set at the bottom of the frame.

[0006] Furthermore, the monitor is a temperature monitor and / or a smoke detector.

[0007] Furthermore, the fire extinguishing tank is a water tank or a gas tank, and the fire extinguishing tank is connected to the detection rod via a fire extinguishing pump.

[0008] Furthermore, there are multiple detection rods, which are disposed separately within the stack.

[0009] Furthermore, the height of the fire extinguishing hood is lower than the height of the frame.

[0010] Furthermore, the traveling wheels include a pair of electric wheels on the end frame and driven wheels on the remaining frames. The beneficial effects of this invention are: the insertable detection rod assembly allows direct monitoring of the temperature and smoke signals inside the stack, enabling fire detection 5-10 minutes earlier than external monitoring; the extinguishing medium reaches the core of the stack directly through the detection rod, significantly improving early fire control efficiency.

[0011] The fire extinguishing cover assembly achieves autonomous movement through a telescopic frame and wheels, increasing coverage efficiency by 3-5 times compared to manual handling of fire extinguishing covers. The flexible fire extinguishing cover, combined with counterweights, can quickly form a sealed isolation space, reducing oxygen supply and effectively preventing the spread of fire.

Detailed Implementation

[0015] The following combination Figure 1-3 The contents of this utility model will be described in detail through specific embodiments. Example

[0016] The emergency fire extinguishing device for the stack 3 includes a detection rod assembly 1 and a self-moving fire extinguishing cover assembly 2; The detection rod assembly 1 is used for fire monitoring and early fire suppression inside the stack 3. The detection rod assembly 1 includes a detection rod 101 mounted on top and a fire extinguishing canister 103 located outside the stack 3. A monitor 102 is installed on the detection rod 101, with at least one monitor 102 installed on each detection rod 101. The monitor 102 is one or a combination of temperature monitor and smoke detector. The monitor 102 is connected to the external control room via wired or wireless means to transmit temperature and smoke detection signals inside the stack 3 in real time. The control room presets a hazard judgment threshold (such as temperature exceeding a preset value or smoke concentration reaching a preset standard). When the signal of the monitor 102 triggers the threshold, an early warning signal can be issued.

[0017] The detection rod 101 has a hollow cavity inside for delivering the extinguishing medium. The cavity is connected to the external fire extinguishing tank 103 via a pipe 105. At the front of the detection rod 101, there are also nozzles 106 that communicate with the cavity, ensuring that the extinguishing medium is evenly sprayed into the stack 3. The front end of the detection rod 101 is conical for easy insertion into the stack 3. To avoid interference between the pipe 105 and the frame, the pipe 105 is embedded in the ground.

[0018] Fire extinguishing tank 103 is located outside the stack 3. Fire extinguishing tank 103 is either a water tank or a gas tank (selected according to the material characteristics of the stack 3; for example, a gas tank containing nitrogen is used for flammable and water-sensitive materials, while a water tank is used for conventional materials). Fire extinguishing tank 103 is connected to the hollow cavity of detection rod 101 via pipeline 105. Fire extinguishing pump 104 is connected in series on pipeline 105. Fire extinguishing pump 104 is electrically connected to the main control room and can be automatically started by the main control room (when the monitor 102 triggers the danger threshold) or manually started. After starting, the water or CO2 in fire extinguishing tank 103 is pumped into the cavity of detection rod 101 and then sprayed into the interior of stack 3 through nozzle 106 to achieve early fire control.

[0019] The fire extinguishing cover assembly 2 is used to quickly isolate the fire in the stack 3 and prevent the fire from spreading due to oxygen supply. The fire extinguishing cover assembly 2 includes multiple telescopic frames 201. The frames 201 are U-shaped. Adjacent frames 201 are hinged together by telescopic components 202. The telescopic components 202 are diamond-shaped telescopic components 202, which are composed of multiple connecting rods hinged together, so that the frames 201 can be unfolded and folded for easy storage. A fire extinguishing hood 203 is installed inside a frame structure composed of multiple skeletons, and multiple fixing rope loops 204 are installed on the fire extinguishing hood 203. An electric release device 205 is fixedly installed on each skeleton 201 for connecting and cooperating with the fixing rope loops 204. The fixing rope loops 204 are hooked into the telescopic locking rod of the electric release device 205. A running wheel 206 is provided at the bottom of the skeleton 201.

[0020] An electric release device 205 is fixedly installed on the end frame 201; a fire extinguishing cover 203 is installed inside multiple frames 201. The fire extinguishing cover 203 has a square structure and is made of soft fireproof material. The electric release device 205 is a control lock (electrically connected to the main control room); under normal conditions, the electric release device 205 is in a locked state, fixing the end of the fixed rope ring 204; when it is necessary to cover the stack 3, the main control room sends a signal to control the electric release device 205 to unlock, and the end fixed rope ring 204 loses its restraint.

[0021] Preferably, a counterweight (such as a counterweight made of fireproof material) is provided on the fire extinguishing cover 203; when the electric release device 205 is unlocked, the counterweight causes the fire extinguishing cover 203 to droop under the action of gravity, so that the fire extinguishing cover 203 fits against the top surface and the surrounding sides of the stack 3, forming a closed isolation space and reducing the amount of oxygen entering the stack 3.

[0022] Preferably, the running wheels 206 include a pair of electric wheels on the end frame 201 and driven wheels on the remaining frames 201; a battery box is provided on the frame 201 for powering the electric wheels and the electric release device 205. The electric wheels are equipped with a remote control module, which can be remotely controlled from the central control room or manually controlled on-site to realize the movement and turning of the fire extinguishing cover assembly 2, ensuring precise movement to directly above the fire pile 3.

[0023] Preferably, the monitor 102 is a temperature monitor and / or a smoke detector. It can monitor the temperature or smoke emission of the stack 3, thereby assessing the risk.

[0024] Preferably, the fire extinguishing tank 103 is a water tank and / or a gas tank, and the fire extinguishing tank 103 is connected to the detection rod 101 through the fire extinguishing pump 104 and the pipeline 105. When a fire occurs, water or CO2 gas can be quickly introduced into the stack 3 as needed to achieve the purpose of local fire extinguishing.

[0025] Preferably, there are multiple detection rods 101, and the monitors 102 are located at the front or middle of the detection rods 101. Depending on the size of the stack 3, several detection rods 101 are inserted, ensuring that the monitors 102 are evenly distributed within the stack 3. The monitors 102 are powered and transmit signals via cables, or wirelessly, transmitting temperature and other signals to the central control room. Monitoring personnel in the central control room then manually assess the temperature changes or values.

[0026] Preferably, the height of the fire extinguishing cover 203 is lower than the height of the frame 201. Example

[0027] The difference between Embodiment 2 and Embodiment 1 is that the electric unhooking device 205 is only installed on the end frame 201, which can reduce the cost of the electric unhooking device; the fixing rope ring 204 is sequentially hung on each portal frame 201 in a "chain connection" manner, and the fixing rope ring 204 at the end is hung on the telescopic rod of the electric unhooking device 205 on the end portal frame 201.

[0028] The usage process of this utility model structure is as follows: Based on the location and size of the stack 3, insert several detection rods 101, and try to evenly distribute the monitors 102 within the stack 3. Based on the signals transmitted back by the monitors 102, determine the risk situation and whether a fire hazard has occurred. If there is a fire hazard, control the fire extinguishing cover 203 to isolate the stack 3 from the air.

[0029] When the monitor 102 detects a hazard, it can immediately start the water pump or gas pump (i.e., fire extinguishing pump 104) to inject water or fire extinguishing gas into the stack 3 through the detection rod 101; control the fire extinguishing cover assembly 2 to move to the position of the fire-damaged stack 3, open the electric release device 205, and after the fixing rope ring 204 at the end is unsecured, the fire extinguishing cover 203 hangs down under the action of the counterweight to form a cover, covering the stack 3 and its surroundings, forming an isolation space, reducing the flow of oxygen, further controlling the fire and effectively preventing its spread.
