DETAILED DESCRIPTION

[0057] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0058] Combination Figure 1-Figure 8 As shown, the utility model is an information safety monitoring device for a thermal power plant, comprising a coal conveying belt 1 arranged in the thermal power plant and used for conveying coal,

[0059] The connecting cover 2 is fixedly mounted on the outer side of the coal conveyor belt 1 and is distributed along the length direction of the coal conveyor belt 1;

[0060] The displacement member 3 is arranged in the connection cover 2 and is located above the coal conveyor belt 1;

[0061] The first mounting frame 4 is arranged on the moving end of the displacement member 3, and can be displaced along the transmission direction of the coal conveyor belt 1 under the driving of the displacement member 3;

[0062] The infrared temperature detection device 5 is arranged on the first mounting frame 4, and the detection end faces the side of the coal conveyor belt 1, and is used to monitor the coal temperature in real time;

[0063] The open fire coal monitoring main control machine 6 is arranged on the first mounting frame 4 and is used to receive the temperature data of the infrared temperature detection device 5;

[0064] The spray assembly 7 is arranged on the first mounting frame 4, and its spray end faces the side of the coal conveyor belt 1. It is controlled by the displacement member 3 and the open fire coal monitoring main control machine 6 to extinguish the fire and cool down the coal surface;

[0065] The open flame smoke adsorption assembly 8 is arranged on the first mounting frame 4, and is used to absorb the open flame smoke to ensure the safety in the thermal power plant.

[0066] The coal conveyor belt 1 realizes the transportation of coal, and the connecting cover 2 provides support and protection for the internal displacement member 3 and other components installed thereon. The displacement member 3 drives the first mounting frame 4 to move along the transmission direction of the coal conveyor belt 1, thereby realizing all-round monitoring of the coal on the entire coal conveyor belt. The infrared temperature detection device 5 monitors the temperature of the coal surface in real time in a non-contact manner, and sends the acquired temperature data to the open fire coal monitoring main control computer 6. The open fire coal monitoring main control computer 6 receives the temperature data from the infrared temperature detection device 5 and compares it with the preset alarm temperature threshold. Once the temperature data exceeds the threshold, the main control computer determines that there is a risk of spontaneous combustion of the coal, and immediately starts the emergency response program. In the emergency response program, the open fire The coal monitoring main control machine 6 sends a control signal to the displacement member 3 to move the first mounting bracket 4 to the area with abnormal temperature. At the same time, the main control machine also sends a start signal to the spray component 7. After receiving the start signal, the spray component 7 immediately sprays water on the coal surface to extinguish the fire and cool it down to prevent the spread of the fire. In addition, during the fire extinguishing process, the open flame smoke adsorption component 8 also starts to work to inhale the open flame smoke generated to ensure the air quality and personnel health in the thermal power plant. Through this working principle, the information safety monitoring device of the thermal power plant realizes real-time monitoring of the coal temperature on the coal conveyor belt, precise positioning of the abnormal temperature area, rapid fire extinguishing and cooling, and adsorption of open flame smoke, providing important guarantees for the safe operation of the thermal power plant.

[0067] The infrared temperature detection device 5 and the open fire coal monitoring main control machine 6 are key components in the information safety monitoring device of the thermal power plant. They work together to realize real-time monitoring and abnormal alarm of coal temperature. The infrared temperature detection device 5 measures the surface temperature of the object in a non-contact manner, and has the advantages of fast, accurate and safe. In the thermal power plant, it is mainly used to monitor the coal temperature on the coal conveyor belt in real time. Once the temperature is abnormally increased, an alarm signal will be issued in time. The selection of specific models will be determined according to the actual application scenario, measurement range, accuracy requirements and other factors. There are many well-known brands on the market that provide various types of infrared temperature detection devices, such as Fluke, Optris, Raytech, etc. The open fire coal monitoring main control machine 6 is the entire monitoring system. It is the core component of the open fire coal monitoring main control machine 6, which is responsible for receiving the temperature data sent by the infrared temperature detection device and analyzing and processing it. When it is found that the temperature data exceeds the preset safety threshold, the open fire coal monitoring main control machine 6 will trigger the alarm mechanism and send control signals to other related equipment at the same time, such as starting the sprinkler device for fire extinguishing, etc. The model selection of the open fire coal monitoring main control machine 6 will also be determined according to actual needs, and its data processing capability, stability, compatibility and other factors need to be considered. It should be noted that the selection of specific models needs to be determined according to the actual application scenarios and needs, and should be selected and configured by professional technicians. In addition, the procurement and use of such equipment should also comply with relevant safety regulations and standards to ensure the normal operation of the equipment and the safety of personnel.

The n-shaped connection cover 2 provides a protective space for other components in the device such as the displacement member 3 and the first mounting frame 4 through its special structure, and allows these components to be easily close to the coal conveyor belt 1 when needed. Its opening design enables the infrared temperature detection device 5 to detect the temperature of the coal on the coal conveyor belt 1 without obstacles, and the spray assembly 7 and the open flame smoke adsorption assembly 8 can also effectively extinguish the coal surface and cool it down and adsorb the smoke.

[0069] In a preferred embodiment, the present invention can be further configured as follows: Figure 3 , Figure 4 As shown; the displacement member 3 comprises:

[0073] The driven pulley 34 is rotatably disposed on the connecting plate 31 and is disposed parallel to the driving pulley 33;

[0074] A synchronous belt 35 is disposed outside the driving pulley 33 and the driven pulley 34; and

[0075] The mounting plate 36 is fixedly mounted on the outer side of the synchronous belt 35 and is interconnected with the first mounting frame 4. The connecting plate 31 provides stable support for the entire displacement member 3. The driving motor 32 serves as the power source for displacement. When the driving motor 32 is started, the active pulley 33 on its output end begins to rotate axially, and the synchronous belt 35 is wrapped around and tensioned on the outer sides of the active pulley 33 and the driven pulley 34. When the active pulley 33 rotates, the driven pulley 34 also rotates synchronously through the transmission action of the synchronous belt 35. When the synchronous belt 35 moves, the mounting plate 36 and the first mounting frame 4 connected thereto also move accordingly. In this way, the infrared temperature detection device 5, the open fire coal monitoring main control computer 6, the spray assembly 7, the open fire smoke adsorption assembly 8 and other components on the first mounting frame 4 can be displaced along the transmission direction of the coal conveyor belt 1 to achieve comprehensive monitoring of the coal on the entire coal conveyor belt.

[0077] In a preferred embodiment, the present invention can be further configured as follows: Figure 4 , Figure 5 As shown; the spray assembly 7 includes:

[0078] The water tank 71 is fixedly mounted on the first mounting frame 4, and a water injection pipe is also provided on the surface thereof;

[0079] The water pump 72 is fixedly mounted on the outside of the water tank 71, and its pumping end penetrates and extends to the inside of the water tank 71;

[0080] A spray pipe 73, one end of which is connected to the water outlet of the water pump 72; and

[0081] The spray head 74 is arranged on the spray pipe 73 and is interconnected with the spray pipe 73. The water tank 71 is used as a storage container for the water source required for fire extinguishing and cooling. A water injection pipe is arranged on the surface of the water tank 71 to facilitate timely replenishment of water to the water tank. The water pump 72 is used to draw water from the water tank 71. When the water pump 72 is started, the water source is pumped into the spray pipe 73. The spray head 74 ensures that the water source can be sprayed out evenly. Under the control of the open fire coal monitoring main control machine 6, once the abnormal surface temperature of the coal is detected and reaches the preset alarm threshold, the main control machine will send a start signal to the water pump 72. After the water pump 72 is started, the water source in the water tank 71 is pumped into the spray pipe 73 and sprayed onto the coal surface through the spray head 74 to achieve fire extinguishing and cooling of the coal.

[0082] In a preferred embodiment, the present invention can be further configured as follows: Figure 4 , Figure 5 As shown; the spray pipe 73 includes a main pipe and a branch pipe, one end of the main pipe is interconnected with the water outlet end of the water pump 72, and the other end of the main pipe is closed. The main pipe is connected to no less than three branch pipes, and the end of the branch pipe away from the main pipe is closed. The spray head 74 is arranged on the outer wall of the branch pipe, and the branch pipe is also connected with a pressure gauge. The main pipe serves as the main channel for water source transmission to ensure that the water source can smoothly flow from the water pump to each branch pipe. The branch pipe distributes the water source in the main pipe to different areas to achieve spraying on a larger range of coal surfaces. The end of the branch pipe away from the main pipe is also closed to ensure that the water source will not leak at the end of the pipe. When the water source flows through the branch pipe, it is evenly sprayed on the coal surface through the spray head 74 to achieve the effect of fire extinguishing and cooling. In addition, the branch pipe is also connected with a pressure gauge for real-time monitoring of the water pressure in the branch pipe. The pressure gauge can be used to timely understand the flow state of the water source to ensure the normal operation of the spray system and timely handle it when an abnormality occurs.

[0083] In a preferred embodiment, the present invention can be further configured as follows: Figure 5 , Figure 6 As shown; the open flame smoke adsorption component 8 includes:

[0084] The exhaust fan 81 is fixedly mounted on the first mounting frame 4, and its exhaust end faces one side of the coal conveyor belt 1;

[0085] The even distribution box 82 is fixedly mounted on the first mounting frame 4;

[0086] The air duct 83 has one end connected to the air outlet of the exhaust fan 81 and the other end passing through and extending to the inner side of the distribution box 82;

[0087] The processing chamber 84 is fixedly mounted on the distribution box 82 and communicated with the distribution box 82;

[0088] The smoke purification component 85 is arranged in the processing chamber 84, and is used to purify harmful gases in the smoke. The exhaust fan 81 is responsible for extracting the smoke generated by the open flame near the belt. When the exhaust fan 81 is started, it will generate suction to suck in the smoke and discharge it through its outlet end. The smoke is introduced into the distribution box 82 through the air duct 83. The distribution box 82 plays a role in preliminarily dispersing the smoke, making the smoke distribution more even, which is convenient for subsequent processing. The smoke enters the processing chamber 84 from the distribution box 82 for further processing. The function of the smoke purification component 85 is to purify the harmful gases in the smoke and can remove toxic and harmful substances in the smoke to meet the emission standards. The processing chamber 84 is also provided with an outlet hole, not shown in the figure, and the purified smoke can be discharged through the outlet hole.

[0089] In a preferred embodiment, the present invention can be further configured as follows: Figure 6 , Figure 8 As shown; the smoke purification component 85 includes:

[0090] The servo motor 851 is fixedly mounted on the processing chamber 84, and its output end penetrates and extends to the inner side of the processing chamber 84;

[0091] The rotating shaft 852 is fixedly mounted on the output end of the servo motor 851;

[0092] A second mounting frame 853, which is connected to the outer side of the rotating shaft 852 by a fastener, and can rotate synchronously with the rotation of the rotating shaft 852;

[0093] Activated carbon 854, disposed on the second mounting frame 853, which can be displaced synchronously with the rotation of the second mounting frame 853; and

[0094] The adsorbent 855 is arranged on the second mounting frame 853, and can be displaced synchronously with the rotation of the second mounting frame 853. The servo motor 851 is used as a driving device. When the servo motor 851 is started, its output end drives the rotating shaft 852 to rotate. The second mounting frame 853 is connected to the outer side of the rotating shaft 852 through a fastener, so the second mounting frame 853 will rotate synchronously with the rotation of the rotating shaft 852. The fastener is preferably a bolt. The activated carbon 854 and the adsorbent 855 are arranged on the second mounting frame 853. As the second mounting frame 853 rotates, they will also be displaced synchronously. This rotation and displacement method makes the activated carbon 854 and the adsorbent 855 It can come into contact with smoke more fully, thereby improving the adsorption efficiency. The activated carbon 854 and the adsorbent 855 each have different adsorption characteristics, and can respectively adsorb different types of harmful gases. Through their joint action, the harmful gases in the smoke are effectively removed, thereby achieving the purpose of purifying the smoke. The activated carbon 854 and the adsorbent 855 can be connected to the second mounting frame 853 by adhesion, which is convenient for subsequent replacement. The adsorbent can be made of metal oxides. This type of adsorbent adsorbs harmful gas molecules on its surface through physical or chemical forces. When the adsorbent reaches a saturated state, its adsorption performance can be restored by heating or replacing a new adsorbent.

[0095] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 , Figure 7 , Figure 8As shown; the air pipe 9 is connected to the distribution box 82, and the other end of the air pipe 9 penetrates and extends into the processing chamber 84. A grid plate 10 is fixedly installed in the distribution box 82, wherein the grid plate 10 and the coal conveyor belt 1 are arranged parallel to each other, and an audible and visual alarm 11 is fixedly installed on the outside of the connecting cover 2. The air pipe 9 is connected between the distribution box 82 and the processing chamber 84 to form a transmission channel for smoke. When the exhaust fan 81 extracts the smoke from the open fire near the coal conveyor belt 1, the smoke first enters the distribution box 82, and the smoke is evenly distributed in the entire distribution box 82 through the dispersion effect of the grid plate 10. The grid plate 10 plays a role in evenly distributing the smoke in the distribution box 82. Since the smoke from the open fire often has uneven concentration and particle distribution, the separation and guidance of the grid plate 10 can make the smoke more evenly distributed in the distribution box, providing more favorable conditions for the subsequent processing steps and improving the efficiency of smoke treatment. In addition, the grid plate also has a certain filtering and blocking effect. It can block the direct passage of larger particles of smoke and dust, causing them to stay on the grid plate or be adsorbed, further reducing the content of harmful substances in the smoke and dust. Subsequently, part of the smoke and dust is introduced into the processing chamber 84 through the air pipe 9 and further processed by the smoke and dust purification component 85. The sound and light alarm 11 is fixedly installed on the outside of the connection cover 2. When abnormal conditions such as abnormal temperature and excessive smoke and dust concentration are monitored, the sound and light alarm 11 will send out sound and light signals to remind the operator to take corresponding measures in time.

[0096] The specific working principle of the information safety monitoring device for a thermal power plant of the utility model is as follows:

[0097] The device monitors the temperature of the coal on the coal conveyor belt 1 in real time through the infrared temperature detection device 5. The detection end of the infrared temperature detection device 5 faces the coal conveyor belt and can accurately capture the temperature change of the coal surface. Once the infrared temperature detection device 5 detects that the coal temperature rises abnormally, that is, exceeds the preset safety threshold, it will immediately send the temperature data to the open fire coal monitoring main control machine 6;

[0098] After receiving the temperature data sent by the infrared temperature detection device 5, the open fire coal monitoring host 6 will quickly analyze the data. If it is confirmed that there is an open fire or high temperature risk, the open fire coal monitoring host 6 will trigger the alarm mechanism and send a control signal to the displacement member 3 and the spray assembly 7 at the same time;

[0099] After the displacement member 3 receives the control signal, the driving motor 32 starts to work, driving the driving pulley 33 to rotate, and the driving pulley 33 drives the driven pulley 34 to rotate together through the synchronous belt 35, thereby driving the mounting plate 36 and the first mounting frame 4 thereon to move along the transmission direction of the coal conveying belt 1. This displacement ensures that the spray assembly 7 and the open flame smoke adsorption assembly 8 can be accurately moved to the area where high temperature or open flame occurs;

[0100] At the same time, the spray assembly 7 also starts to work, the water pump 72 draws water from the water tank 71, and distributes the water to each spray head 74 through the spray pipe 73. The spray head 74 sprays the water evenly onto the surface of the high-temperature or burning coal to extinguish the fire and reduce the temperature;

[0101] On the other hand, the open flame smoke adsorption assembly 8 also starts to work, and the exhaust fan 81 is started. Its exhaust end sucks in the smoke generated by the open flame and transports it to the distribution box 82 through the air duct 83. In the distribution box 82, the grid plate 10 evenly distributes the smoke to ensure that the smoke can fully enter the treatment chamber 84;

[0102] The smoke purification assembly 85 in the treatment chamber 84 further processes the smoke. The servo motor 851 drives the rotating shaft 852 to rotate, driving the second mounting frame 853 and the activated carbon 854 and the adsorbent 855 thereon to rotate together. The activated carbon 854 and the adsorbent 855 fully contact with the smoke during the rotation process, adsorbing the harmful gases therein, thereby purifying the smoke.

[0103] In addition, the sound and light alarm 11 on the outside of the connection cover 2 will also work when the open fire coal monitoring host 6 triggers the alarm mechanism, and send out sound and light signals to remind the operator to respond in time and take further measures;

[0104] In summary, the information-based safety monitoring device of the thermal power plant realizes effective monitoring and timely handling of high temperature and open flames on the coal conveyor belt of the thermal power plant through the information-based collaborative work of multiple links such as infrared temperature detection, displacement drive, sprinkler fire extinguishing, smoke adsorption and purification, and sound and light alarm, thereby ensuring the safe operation of the thermal power plant.
