[0002] A thermal power plant is a factory that relies on fuel combustion to generate heat energy. In a thermal power plant, the coal storage area usually requires a closed coal yard. The closed coal yard has many important functions. It can greatly reduce the flying coal dust, avoid pollution to the surrounding environment, meet environmental protection requirements, and prevent the coal from being disturbed by natural factors such as wind and rain, reduce the moisture content of the coal, ensure the stability of the coal quality entering the furnace, and thus improve combustion efficiency. In addition, the closed structure facilitates better control of coal storage, reduces the risk of coal spontaneous combustion, improves the safety of the power plant, and provides a strong guarantee for the continuous and stable production of electricity.

[0003] Closed coal yards are prone to spontaneous combustion under certain conditions due to the large amount of coal stored, and may also cause fires due to electrical failures, human errors, etc. Existing closed coal yards are usually equipped with simple sprinkler systems to prevent coal spontaneous combustion and fires. However, they are unable to carry out targeted and precise fire extinguishing in the fire area. This is because the sprinkler system can often only spray water over a large area and cannot accurately spray water on the fire point, which makes it impossible to control the fire in a timely and effective manner. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when the above-mentioned equipment is in use, it is impossible to carry out targeted and accurate fire extinguishing in the fire area during the use of the closed coal yard, resulting in the inability to control the fire in a timely and effective manner, and thus a closed coal yard fire protection and combustion prevention system is proposed.

[0010] Preferably, four ventilation shutters are fixedly installed on the outer wall of the closed coal yard body.

[0011] Preferably, a controller is fixedly mounted on one side of the outer wall of the closed coal yard body.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] In the present invention, through the interaction of the various components of the device, the precise positions of the four fire-fighting water cannons can be flexibly adjusted to achieve targeted and accurate spraying at the fire source. This design ensures the maximum fire extinguishing effect, effectively suppresses the rapid spread of the fire, and strives to extinguish the flames in the early stages. This targeted fire extinguishing method not only improves the fire extinguishing efficiency, but also minimizes the losses and risks that may be caused by fires inside closed coal yards.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figure 1-Figure 4 As shown, the utility model provides a closed coal yard fire prevention and combustion prevention system, including a closed coal yard main body 1, the outer wall of the closed coal yard main body 1 is fixedly connected to two water tanks 2, the output ends of the two water tanks 2 are fixedly connected to water outlet pipes 3, the output ends of the two water outlet pipes 3 are fixedly connected to water pumps 4, the output ends of the two water pumps 4 are fixedly connected to delivery pipes 5, the output ends of the two delivery pipes 5 are fixedly connected to connecting pipes 6, the output ends of the two connecting pipes 6 are fixedly connected to a group of spring telescopic water pipes 7, the output ends of the two groups of spring telescopic water pipes 7 are fixedly connected to fire water monitors 8, the inner wall of the closed coal yard main body 1 is fixedly connected to two groups of mounting plates 9, one side of the outer wall of the two groups of mounting plates 9 is provided with a slide groove 10, the inner wall of the two groups of slide grooves 10 is slidably embedded with a slider 11, the inner wall of the two groups of sliders 11 is threadedly connected to a threaded rod 12, one side of the outer wall of the two groups of threaded rods 12 is fixedly connected to a servo motor 13, and the outer wall of the two groups of threaded rods 12 is fixedly sleeved with a bearing 14.

[0024] The effect achieved by the entire embodiment 1 is that, first, an infrared thermal imaging camera 15 is used to perform a full-scale temperature scan on the interior of the closed coal yard body 1 to detect potential fire points or high-temperature areas. Once the specific location of the fire point or high-temperature area is determined, the control system will respond immediately and start the four servo motors 13 respectively. The output ends of the four servo motors 13 drive the corresponding threaded rods 12 to rotate. As the threaded rods 12 rotate, the slider 11 connected thereto realizes precise left and right movement inside the slide 10. This mechanical linkage mechanism enables the fire water monitor 8 to quickly and accurately approach the fire point or high-temperature area. Subsequently, the fire water monitor 8 uses its internal rotation and pitch adjustment mechanism to automatically Adjust its spraying direction to ensure that the nozzle of the water cannon is accurately aimed at the fire point or high-temperature area. At this time, the system starts two water pumps 4. These two water pumps 4 efficiently draw water from the corresponding water tank 2 and pressurize it to ensure that the water flow has sufficient spraying force. The pressurized water flow is quickly transmitted to the four fire water cannons 8 through the connecting pipe 6. Once the water flow reaches the fire water cannon 8, these water cannons immediately aim at the fire point or high-temperature area for targeted and powerful spraying, effectively suppressing the spread of fire and extinguishing the flames as much as possible. This process not only improves the fire extinguishing efficiency, but also ensures the safety and accuracy of the fire extinguishing operation, thereby minimizing the losses and risks that may be caused by fire inside the closed coal yard.

[0025] Example 2, as Figure 2-Figure 4 As shown, an infrared thermal imaging camera 15 is fixedly installed on the inner wall of the closed coal yard main body 1, a smoke sensor 16 is fixedly installed on the inner wall of the closed coal yard main body 1, two groups of mounting holes 17 are opened on the outer wall of the closed coal yard main body 1, ventilation fans 18 are fixedly inserted into the inner walls of the two groups of mounting holes 17, four ventilation shutters 19 are fixedly installed on the outer wall of the closed coal yard main body 1, and a controller 20 is fixedly installed on one side of the outer wall of the closed coal yard main body 1.

[0026] The effect achieved by the entire embodiment 2 is that when the smoke sensor 16 detects that the smoke concentration inside the closed coal yard body 1 exceeds the preset safety threshold, the control system will immediately respond and start two sets of ventilation fans 18. After the two sets of ventilation fans 18 are started, strong air flow will be generated to form an effective ventilation effect. This forced ventilation can quickly and effectively discharge the smoke and harmful gases in the coal yard, creating a clearer and safer working environment for subsequent fire fighting and rescue work. At the same time, the operation of the ventilation fans 18 also helps to reduce the temperature inside the coal yard, and takes away some heat by enhancing air convection, thereby suppressing the further expansion of the fire to a certain extent, and gaining precious time for controlling the fire.

[0027] Working principle: When in use, firstly, a high-precision infrared thermal imaging camera 15 is used to conduct a full range of temperature anomaly detection inside the closed coal yard body 1 to accurately identify potential fire points or high-temperature areas. Once a fire or an abnormally heated area is found, the control system immediately starts the four servo motors 13. The output ends of the four servo motors 13 accurately drive the threaded rods 12 fixedly connected to one side of their respective outer walls to rotate, thereby driving the slider 11 to move left and right in the corresponding slide 10 efficiently and stably. This process ensures that the fire water monitor 8 can adjust its position quickly and accurately, gradually approaching the fire point or the optimal fire extinguishing angle of the high-temperature area. At the same time, the fire water monitor 8 uses its built-in infrared detection device to track the specific location of the fire source in real time, and automatically adjusts its spray direction to ensure that the high-pressure water column is accurately aimed at the fire source to achieve precise strikes. Subsequently, The control system activates two high-efficiency water pumps 4, which quickly draw a large amount of water from their respective corresponding water tanks 2 and pressurize the water flow through a built-in pressure mechanism. The pressurized water flow is quickly transported to four fire water monitors 8 through two connecting pipes 6, providing them with sufficient and powerful fire-fighting water sources. The four fire water monitors 8 then carry out concentrated and continuous targeted spraying on the fire source, effectively suppressing the spread of the fire until the fire source is completely extinguished. During this process, if the smoke sensor 16 detects that the smoke concentration inside the closed coal yard body 1 exceeds the safety standard, the control system will immediately start the emergency ventilation mechanism, that is, two sets of high-power ventilation fans 18. After these two sets of fans are started, they generate strong airflow, forming an efficient ventilation effect, and quickly discharge the smoke, harmful gases and some heat in the coal yard, providing a clear and safe working environment for subsequent fire fighting and rescue work. At the same time, it also helps to reduce the overall temperature inside the coal yard and prevent the fire from further deteriorating due to high temperature.
