[0038] A thermal power plant is a power plant that generates heat energy by burning fuel and then converts the heat energy into electrical energy. It is currently one of the world's main sources of electricity supply and is widely used in various countries and regions. The working principle of a thermal power plant is to generate high-temperature and high-pressure steam by burning fuel, and then use the steam to drive the steam turbine to rotate the generator, converting mechanical energy into electrical energy.
[0039] my country's thermal power plants mainly rely on coal as fuel for power generation. Conveyor belts are usually used to transport coal in thermal power plants. Due to the harsh coal transportation environment, low visibility at night, and light pollution in the on-site lighting, the monitoring equipment cannot effectively monitor the on-site conditions in real time, which is not conducive to the effective monitoring of the on-site equipment and the coal conveyor belt conditions by the operating personnel.
[0040] In order to solve the above problems, the utility model proposes a night monitoring device, which aims to provide a night monitoring device with better monitoring effect on coal transportation site. Figures 1 to 5 The present invention is a schematic structural diagram of an embodiment of the nighttime monitoring device provided by the present invention.
[0041] Please refer to Figures 1 to 5 The utility model proposes a nighttime monitoring device 1000, comprising a bracket 1, a camera device 2 and a fill light device 3, wherein the camera device 2 is rotatably disposed on the bracket 1, and the fill light device 3 comprises a plurality of light sources 31, which are disposed on the sides of the camera device 2 and can rotate with the camera device 2.
[0042] In the technical solution of the utility model, a night monitoring device 1000 and a coal transportation system are proposed, wherein the night monitoring device 1000 includes a bracket 1, a camera device 2 and a fill light device 3, the camera device 2 is rotatably arranged on the bracket 1, the fill light device 3 includes a plurality of light sources 31, the plurality of light sources 31 are arranged on the side of the camera device 2 and can rotate with the camera device 2, and a plurality of light sources 31 for fill light are arranged on the side of the camera device 2. Since one monitoring device needs to cover multiple conveyor belts 2000, the plurality of light sources 31 will rotate with the rotation of the camera device 2 and remain relatively still with the camera device 2, thereby ensuring high visibility and clear monitoring in the monitoring area, thereby achieving effective monitoring of the site.
[0043] Furthermore, in order to improve the image quality of the coal transportation site monitoring, the camera device 2 also includes a night vision device 24. For details, please refer to Figure 1 The night vision device 24 is installed in the housing 21. The night vision device 24 can provide clear images under low light conditions. The coal transportation site usually generates a large amount of infrared radiation. The night vision device 24 captures these radiations through the built-in infrared detector and then converts them into visible light images so that the staff can monitor and observe at night or in low light conditions. The image processing technology of the night vision device 24 can enhance weak infrared signals and filter out interference factors in the environment, thereby providing clear and bright images, allowing the staff to monitor the coal transportation site in real time at night or in low light environments, improving the scope and effect of monitoring, and helping to discover problems in time and take measures to ensure the safety and stability of the coal transportation process. Therefore, installing a night vision device 24 for coal transportation site monitoring is a very effective measure to improve the safety and reliability of the coal transportation process and ensure the life safety of the staff and the normal operation of the equipment.
[0044] In order to reasonably arrange the fill light matrix to form a clearer fill light area with a larger coverage area, the fill light device 3 also includes a mounting portion 32. For details, please refer to Figure 4The mounting part 32 includes a horizontal bar 321 and two vertical bars 32 respectively arranged at both ends of the horizontal bar 321. The horizontal bar 321 and the two vertical bars 32 together form an H-shaped bracket 1. The H-shaped bracket 1 is fixed to the rear side of the housing 21 of the camera 22 by threaded connection. A light source 31 is arranged at both ends of each vertical bar 32, and there are four light sources 31 in total. The four light sources 31 together emit strong light in front of the lens of the camera 22. The four light beams cross each other to form a fill light matrix. The fill light matrix provides light for the position photographed by the lens, thereby avoiding the problem of unclear monitoring in low light conditions at night. It should be further explained that the light source 31 is a searchlight 311. The searchlight 311 can provide a strong light source 31 to illuminate the coal transportation site, so that the staff can see the situation on the site more clearly. At the same time, the scene in the monitoring screen will be clearer, which is helpful for the staff to monitor and analyze the coal transportation site in real time. In addition, in some emergency situations, the searchlight 311 can provide fast lighting, so that the staff can find the required equipment or tools more quickly, and improve the emergency response capability.
[0045] Since the searchlight 311 has a certain weight, in order to improve the bearing capacity of the mounting part 32, the crossbar 321 and the vertical bar 32 are an integrated structure, which can provide higher strength and stability, and can better support and fix the searchlight 311 to prevent it from shaking or falling off during use. In addition, the use of an integrated structure can reduce the number of joints, thereby reducing the risk of corrosion. This can extend the service life of the H-shaped bracket 1 and reduce the cost of maintenance and replacement; since there are no connecting parts, the integrated H-shaped bracket 1 is more convenient and quick to install, which can reduce installation time and labor costs.
[0046] In order to fine-tune the vertical angle of the camera 22, the camera device 2 also includes a mounting platform 23. For details, please refer to Figure 2 The mounting platform 23 is hingedly fixed to the shell 21, and a fixing hole 21a is provided on the side of the shell 21 facing the mounting platform 23. Correspondingly, a rotating shaft is provided on the side of the mounting platform 23 facing the shell 21, and the rotating shaft and the fixing hole 21a are interference fit. Through the rotational fit of the rotating shaft and the fixing hole 21a, due to the frictional contact between the outer peripheral wall of the rotating shaft and the fixing hole 21a, when no manual adjustment is made, the camera 22 is at a fixed angle. When the camera 22 needs to be adjusted up and down, it can be adjusted manually.
[0047] In order to cover a larger monitoring area, the camera 22 is rotatably mounted on the bracket 1. To realize the rotation of the camera 22, the mounting platform 23 is provided with a driving motor 25. A mounting hole 1a is formed at one end of the bracket 1, and the output end 251 is plugged and fixed to the mounting hole 1a. For details, please refer to Figure 3The output end 251 of the driving motor 25 is connected to the bracket 1. By rotating the camera device 2, a wider area can be covered, the monitoring blind area can be reduced, and the comprehensiveness and accuracy of the monitoring can be improved. The driving motor 25 can make the camera device 2 rotate quickly and flexibly, and adjust the monitoring angle and direction as needed to better capture the target object; in addition, it can promptly detect abnormal situations in the monitoring area, and respond and process them quickly, thereby improving the efficiency and effect of monitoring.
[0048] In order to reduce the overall weight of the device, the bracket 1 is formed with a hollow portion 1b. For details, please refer to Figure 1 , the hollow part 1b can reduce the material usage of the bracket 1, thereby reducing the overall weight of the bracket 1. This can facilitate installation and handling, and can also reduce the burden of the bracket 1 on the installation structure. The hollow part 1b can provide space for cables to pass through, which is convenient for the arrangement and management of cables. This can reduce the clutter of cables and improve the safety and reliability of cables. The hollow part 1b can also add a simple and fashionable design sense to the bracket 1, making it more in line with the aesthetic requirements of the overall environment. The hollow design can also increase the three-dimensional sense and layering of the bracket 1.
[0049] The utility model also proposes a coal transportation system, which includes at least two conveyor belts 2000 and a night monitoring device 1000. The conveyor belts 2000 are arranged at intervals. The specific structure of the night monitoring device 1000 refers to the above embodiment. Since the coal transportation system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.
[0050] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
