[0044] like Figures 1 to 3 As shown, one embodiment of the present invention provides a high-temperature fire extinguishing device for a belt conveyor roller. The belt conveyor includes a workbench 1, and the fire extinguishing device includes:

[0045] A fixing frame 6 is externally provided on the workbench 1, and a fixing plate 8 is provided on the fixing frame 6, and the fixing plate 8 is located above the workbench 1;

[0046] The spray cooling assembly 10 is arranged outside the workbench 1. The spray cooling assembly 10 includes a double-ended pipe 107, which is arranged on the fixed plate 8. The outlet of the double-ended pipe 107 passes through the fixed plate 8 and is arranged toward the workbench 1. One end of the double-ended pipe 107 is connected to a first branch pipe 102. The end of the first branch pipe 102 away from the double-ended pipe 107 is connected to the main delivery pipe 101. The main delivery pipe 101 is also connected to a second branch pipe 103. A first nozzle 108 is provided on the side of the double-ended pipe 107 facing the workbench 1.

[0047] The temperature measuring component 11 is arranged on the side of the workbench 1 .

[0048] Among them, the fire extinguishing device includes a spray cooling component 10 arranged above the workbench 1, that is, above the conveyor belt 4. When in use, the main conveying pipe 101 is connected to the external water pipe with a docking flange, and the end of the first branch pipe 102 is connected to the double-headed pipe 107. The water is discharged through the first nozzle 108 to cool the conveyor belt 4, and at the same time, the material on the conveyor belt 4 can also be dusted. The second branch pipe 103 is connected to the second nozzle 109. The second nozzle 109 is located on the side of the workbench 1 and at the starting end of the conveyor belt 4, so it can cool the roller 2 at the starting end. The fire extinguishing device can cool and extinguish the conveyor belt and the outside of the belt conveyor, thereby improving the efficiency of cooling and fire extinguishing, and thus enabling the belt conveyor to quickly return to working state.

[0049] Specifically, a motor is provided at one end of the workbench 1 of the belt conveyor, and the motor is connected to a roller 2. A driven roller is provided at the end of the workbench 1 away from the motor, and the conveyor belt 4 is wound around the roller 2 and the driven roller. The fixing frame 6 includes support rods, which are located on both sides of the width direction of the workbench 1. Multiple support rods can be provided on each side, and a fixing plate 8 is provided on the end of the support rod away from the workbench 1. At least part of the spray cooling component 10 is provided on the fixing plate 8, wherein the outlet of the double-headed pipe 107 is provided on the fixing plate 8, and the outlet faces one side of the conveyor belt 4. The double-headed pipe 107 is also connected to the first branch pipe 102. A first nozzle 108 is provided at the outlet of the double-headed pipe 107, and the first nozzle 108 faces the conveyor belt 4 to achieve water spray cooling of the conveyor belt 4.

[0050] It should be noted that the end of the first branch pipe 102 away from the double-headed pipe 107 is connected to the main conveying pipe 101, and the main conveying pipe 101 is also connected to the second conveying pipe. The main conveying pipe 101 is provided with an electric valve 105 and a pressure gauge 106, and the electric valve 105 is connected in parallel with a manual valve 104. The first branch pipe 102 and the second branch pipe 103 are also provided with a manual valve 104 respectively. The combination of the electric valve 105 and the hand valve 104 can ensure that the normal operation of the main conveying pipe 101 will not be affected when a valve fails, thereby ensuring the cooling and dust reduction of the conveyor belt 4. Among them, the manual valve 104 on the first branch pipe 102 and the second branch pipe 103 can also be connected in parallel with an electric valve 105 (not shown in the figure). In this way, the manual valve 104 is a normally closed valve. When the controller signal is received, the electric valve 105 door opens and the spray cooling component 10 works. After the work is completed, the electric valve 105 can be closed. When the electric valve 105 fails, the staff can manually open the hand valve 104 after receiving the signal from the controller, which can also achieve the same function.

[0051] Figure 4 A schematic diagram of the installation position of a temperature measurement component according to an embodiment of the present invention; Figure 5 3D is a perspective view of a temperature measurement component according to an embodiment of the present invention.

[0052] In one possible implementation, Figure 4 and Figure 5 As shown, the temperature measurement component 11 includes:

[0053] The monitoring frame 111 is provided on the side of the workbench 1. The monitoring frame 111 is internally connected to a plug-in frame 112. The plug-in frame 112 can move within the monitoring frame 111. The plug-in frame 112 is provided with a second nozzle 109 at both ends. The second nozzle 109 is connected to the second branch pipe 103.

[0054] The vertical plate 114 is disposed on the plug-in frame 112 and is located between the two second nozzles 109 . A driving motor 115 is provided on the second vertical plate 114 , and a temperature measuring instrument 116 is indirectly connected to the output shaft of the driving motor 115 .

[0055] Among them, when there is only one temperature measuring component 11, it is set at the roller 2 at the starting position of the conveyor belt 4, so that the roller 2 can be effectively cooled. When there are multiple temperature measuring components 11, one of them should also be set at the roller 2 of the workbench 1, and the remaining temperature measuring components 11 can be set at intervals along the length direction of the workbench 1. A fixed handle 113 is provided at one end of the plug-in frame 112, and the monitoring frame 111 is set on the side of the belt conveyor body. By holding the fixed handle 113, the plug-in frame 112 is inserted into the interior of the conveyor belt 4 through the monitoring frame 111, and the second nozzle 109 and the thermometer 116 are aligned with the roller 2 of the workbench 1. At this time, at least part of the plug-in frame 112 is still located in the monitoring frame 111, and the plug-in frame 112 is supported by the monitoring frame 111. After the docking rack 112 moves to the vicinity of the drum 2, the temperature of the drum 2 is monitored by the thermometer 116 on the vertical plate 114. When the temperature of the drum 2 is not less than the preset value, it can be connected to the sound and light alarm, and an alarm is sounded through the sound and light alarm to remind the staff to deal with the safety hazards in time, and further transmit the information to the controller. The controller controls the spray cooling component 10 to operate, and sprays and cools the conveyor belt 4 and the material thereon through the first nozzle 108, and cools the drum 2 through the second nozzle 109, thereby achieving cooling from the source and preventing the drum 2 from continuing to heat up and transferring heat to the conveyor belt 4 and the material thereon.

[0056] It is understood that when multiple temperature measuring assemblies 11 are provided, the docking frame 112 can be pushed into the middle portion of the conveyor belt 4 to measure and cool the middle portion of the conveyor belt 4. Simultaneously, the temperature conditions of the multiple temperature measuring instruments 116 can be integrated to activate the controller. Spraying and cooling multiple portions of the conveyor belt 4 can improve cooling efficiency, allowing the belt conveyor to return to operation more quickly.

[0057] It should be noted that the output shaft of the drive motor 115 is indirectly connected to the thermometer 116. A horizontal plate can be installed on the vertical plate 114. A screw rod is installed in the horizontal plate, and a nut is installed on the screw rod. The output shaft of the drive motor 115 is fixedly connected to the screw rod, and the thermometer 116 is fixed to the nut. The horizontal plate is located between the two second sprinkler heads. In this way, the operation of the drive motor 115 can drive the thermometer 116 to move back and forth between the two second sprinkler heads 109, expanding the temperature measurement range of the thermometer 116 and improving the accuracy of temperature measurement. The monitoring frame 111 has an avoidance groove to facilitate the passage of the plug-in frame 112.

[0058] Figure 6It is a schematic diagram of a clearing component according to an embodiment of the present invention.

[0059] In one possible implementation, Figure 6 As shown, the fire extinguishing device also includes:

[0060] The dredging component 7 is arranged on the fixed frame 6. The dredging component 7 is located at the fixing clamp close to the workbench 1, and the dredging component 7 is located between the fixing plate 8 and the workbench 1. The dredging component 7 is used to evenly distribute the material on the workbench 1.

[0061] Among them, by setting up the dredging component 7, the materials on the conveyor belt 4 can be spread out evenly, avoiding the problem of difficulty in heat dissipation of the conveyor belt 4 caused by material accumulation, and difficulty in cooling and extinguishing fire in the event of a high-temperature fire.

[0062] In a feasible embodiment, the dredging component 7 includes:

[0063] Support plate 701, fixedly connected to the fixing clamp;

[0064] The driving motor 702 is arranged on the side of the supporting plate 701 facing the fixing plate 8. The output shaft of the driving motor 702 is provided with a first gear 703. The first gear 703 is engaged with the second gear 704. The second gear 704;

[0065] The second gear 704 is meshed with the first gear 703 , and a connecting shaft is fixedly connected to the center of the second gear 704 .

[0066] Among them, a hinged baffle 705 is provided at one end of the connecting shaft away from the second gear 704, and a dredging tooth 706 is provided on the hinged baffle 705. The direction of the support plate 701 toward the dredging tooth 706 is the conveying direction of the material.

[0067] It should be noted that, by setting up the dredging component 7, the materials transported on the top of the conveyor belt 4 can be evenly distributed. The materials on the conveyor belt 4 are often piled up. When a fire or abnormal high temperature occurs, it is not easy to extinguish the fire and reduce the temperature in time, causing economic losses. Therefore, after the materials are evenly distributed by the dredging component 7, the efficiency of dust reduction, cooling and fire extinguishing can be improved.

[0068] Specifically, the drive motor 702 drives the first gear 703 to rotate, which in turn drives the meshed second gear 704 to rotate. The second gear 704 then drives the connecting shaft to rotate, thereby adjusting the angle between the hinged baffle 705 connected to the connecting shaft and the conveyor belt 4. This allows for different spread thicknesses to be adjusted based on the material, and the material is evenly spread using the dredging teeth 706. It is understood that the drive motor 702 is only used when initially adjusting the spread thickness. After determining the distance between the hinged baffle 705 and the conveyor belt 4, the drive motor 702 stops and the hinged baffle 705 is fixed. A gear housing is provided outside the first gear 703 and the second gear 704 to ensure the reliability and stability of the meshing of the first gear 703 and the second gear 704.

[0069] In a feasible embodiment, the fire extinguishing device includes a controller, the controller is connected to the spray cooling assembly 10, the temperature measuring instrument 116 is connected to the controller, and the controller is configured to control the start and stop of the workbench 1.

[0070] Among them, by cooperating with the controller, automatic control of fire extinguishing, cooling and dust reduction can be achieved, thereby improving the efficiency of fire extinguishing and dust reduction.

[0071] In a feasible embodiment, the controller receives the monitored temperature of the thermometer 116 and controls the opening and closing of the spray cooling component 10 according to the monitored temperature.

[0072] Among them, the controller controls the opening and closing of the spray cooling component 10 in time according to the monitoring temperature of the thermometer 116, which can improve the working speed of the spray cooling component 10, respond in time, and improve the fire extinguishing and cooling efficiency.

[0073] In a feasible embodiment, the thermometer 116 is an infrared thermometer.

[0074] Among them, in this embodiment, the thermometer 116 adopts an infrared thermometer, which is a non-contact temperature measurement tool suitable for dynamic targets such as rotating machinery and materials on conveyor belts. The response time is usually in milliseconds (such as 0.1 seconds), which is suitable for rapid scanning of large areas and improving the accuracy and reliability of temperature measurement.

[0075] Another embodiment of the present invention provides a method for extinguishing a high-temperature fire on a belt conveyor roller. Utilizing the above-mentioned fire extinguishing device, the method comprises the following steps:

[0076] Monitor the temperature outside the workbench based on the temperature measurement component and obtain monitoring data;

[0077] Determine whether the monitoring data is not less than the preset value, if yes, proceed to the next step, otherwise repeat the previous step;

[0078] Control the operation of the spray cooling component to cool the workbench.

[0079] The temperature measuring assembly 11 is first installed at the initial position of the workbench 1, i.e., at the position of the roller 2. The docking frame 112 is then pushed under the workbench 1, and the temperature of the roller 2 is monitored using the thermometer 116. When the temperature of the roller 2 is not less than a preset value, a signal is transmitted to the controller, which controls the operation of the spray cooling assembly 10, turning it on to spray and cool the area above the conveyor belt 4 and the roller 2. When the temperature monitored by the thermometer 116 is lower than the set value, the controller can turn off the spray cooling assembly 10. Specifically, the first branch pipe 102 uses the first nozzle to cool and extinguish the conveyor belt 4 and the materials thereon over a long distance, while the second nozzle 109 on the second branch pipe 103 cools and extinguishes the roller 2.

[0080] It should be noted that the preset value is 80°C. That is, when the temperature of the drum 2 monitored by the thermometer 116 is ≥80°C, the controller controls the spray cooling assembly 10 to operate, with a set value of 60°C. When the rolling temperature monitored by the thermometer 116 is <60°C, the controller controls the spray cooling assembly 10 to stop operating. The thermometer 116 can move within a certain range of the drum 2, so the average of multiple monitored values ​​or the highest temperature value formed by the reciprocating movement can be used as the final monitoring data.

[0081] In this embodiment, a spray cooling component 10 is provided. When in use, the main delivery pipe 101 is connected to the external water pipe using a docking flange. The electric valve 105 is controlled to switch operation by a controller. When a fault occurs, the manual valve 104 can be opened and closed by the staff. The valve adopts a combination of manual and automatic methods to ensure that the normal use of the spray cooling component 10 will not be affected when the valve fails.

[0082] In summary, the fire extinguishing device and fire extinguishing method for high temperature of belt conveyor roller are provided, by setting the spray cooling component 10. When in use, the main conveying pipe 101 is connected to the external water pipe by a docking flange, and the electric valve 105 is switched on and off by the controller. The hand valve 104 and the electric valve 105 are combined in manual and automatic modes to ensure that the normal use of the spray cooling component 10 is not affected when the valve fails. The first branch pipe 102 is connected to the double-headed pipe 107 at one end away from the main conveying pipe 101, and water is sprayed through the first nozzle 108. Sprinkling on the top of the workbench 1 (the conveyor belt 4 and its materials) not only achieves the purpose of cooling the workbench 1, but also can achieve the purpose of reducing dust on the materials on the top of the workbench 1. At the same time, the second branch pipe 103 is connected to the second nozzle 109. The water sprayed by the second nozzle 109 can directly cool the drum 2 inside the workbench 1. The combination of the spray cooling component 10 and the controller can realize the full automatic completion of watering, stopping spraying and other actions without human intervention, and has manual and remote control watering and stopping spraying functions.

[0083] In addition, by setting up the temperature measuring component 11, when in use, the monitoring frame 111 is set on the side of the workbench 1 and is located near the roller 2. By holding the fixed handle 113, the plug-in frame 112 is inserted into the interior of the workbench 1. The plug-in frame 112 drives the thermometer 116 and the second nozzle 109 closer to the front side of the roller 2 in the workbench 1. The temperature of the workbench 1 can be monitored in real time through the thermometer 116. The thermometer 116 is also equipped with an audible and visual alarm. When the temperature of the workbench 1 exceeds the preset value, it can directly output an alarm to remind the staff to deal with the safety hazards in time, and further transmit the information to the controller. The controller directly controls the operation of the spray cooling component 10 to cool the roller 2 of the workbench 1 and the conveyor belt 4 and materials on the workbench 1.

[0084] In addition, by setting up the dredging component 7, the materials transported from the top of the workbench 1 can be evenly distributed. The materials transported from the top of the workbench 1 are often piled up, and it is not easy to extinguish the fire when the piled materials catch fire. By the time it is discovered, property damage is likely to occur. The output shaft of the driving motor 702 drives the first gear 703 and the second gear 704 to engage with each other, so as to drive the hinged baffle 705 to drive the dredging teeth 706 to change their inclination angle. The dredging teeth 706 can adjust the thickness of small material accumulation, so that the material can be cooled in time.

[0085] In the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more, unless otherwise clearly defined.
