[0026] The embodiments of the present disclosure will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present disclosure and should not be construed as a limitation to the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0027] Such as Figure 1 and Figure 3As shown, the embodiment of the present disclosure proposes a coal bunker 100 safety protection system, including: a baffle 1, a detection module 2, a drive device 3 and a control module 4, one end of the baffle 1 is hinged on one side of the entrance of the coal bunker 100, the detection module 2 is used to detect the operating status of the belt conveyor, wherein the discharge end of the belt conveyor is located on the side of the entrance of the coal bunker 100 away from the baffle 1, the drive device 3 is transmission-connected to the baffle 1, and the drive device 3 is used to drive the baffle 1 to rotate, the signal input end of the control module 4 is connected to the signal output end of the detection module 2, and the signal output end of the control module 4 is connected to the signal input end of the drive device 3, the control module 4 is used to control the drive device 3 to act when the belt conveyor is running, so that the baffle 1 opens the entrance of the coal bunker 100, and, when the belt conveyor stops, to control the drive device 3 to act, so that the baffle 1 closes the entrance of the coal bunker 100.

[0028] It is understandable that when the belt conveyor is running, the control module 4 controls the driving device 3 to operate according to the operating status of the belt conveyor detected by the detection module 2, so that the baffle 1 opens the entrance of the coal bunker 100, thereby ensuring that the coal transported by the belt conveyor can stably enter the coal bunker 100. When the belt conveyor is stopped, the control module 4 controls the driving device 3 to operate according to the operating status of the belt conveyor detected by the detection module 2, so that the baffle 1 closes the entrance of the coal bunker 100, thereby preventing people or materials from falling into the entrance of the coal bunker 100. Therefore, the automatic control of the control module 4 can effectively reduce the occurrence of falling accidents without affecting the conveyance of coal to the coal bunker 100 by the belt conveyor, thereby effectively improving the safety of the coal bunker 100.

[0029] It should be noted that the entrance of the coal bunker 100 is used for the entry of coal, which is located at the top of the coal bunker 100. The coal transported in the horizontal or nearly horizontal direction in the belt conveyor falls into the entrance of the coal bunker 100, thereby realizing the loading of coal.

[0030] The baffle 1 is used to open or close the entrance of the coal bin 100. The specific type of the baffle 1 can be set according to actual needs and is not limited to this. For example, the baffle 1 can be a plate body that is close to the size of the entrance of the coal bin 100, and an annular groove that adapts to the baffle 1 is provided around the entrance of the coal bin 100. The annular groove is provided with a sealing ring. When the baffle 1 covers the entrance of the coal bin 100, the four sides of the baffle 1 are located in the annular groove and abut against the sealing ring.

[0031] The detection module 2 is used to detect the operating status of the belt conveyor. The specific type of the detection module 2 can be set according to actual needs and is not limited to this. For example, the detection module 2 can be a current sensor, which uses the current sensor to detect the motor current in the belt conveyor to determine whether the belt conveyor is running; the detection module 2 can be a rotary encoder, which uses the rotary encoder to detect the rotation of the roller in the belt conveyor to determine whether the belt conveyor is running.

[0032] The driving device 3 is used to drive the baffle 1 to rotate. The specific type of the driving device 3 can be set according to actual needs, and no limitation is imposed thereon.

[0033] The control module 4 is used to control the action of the driving device 3 to realize the rotation of the baffle 1. The specific type of the control module 4 can be set according to actual needs, and no limitation is imposed thereon. For example, the control module 4 can be a controller, a microcontrol unit, etc.

[0034] As Figure 2 shown, in some embodiments, the driving device 3 includes: a hydraulic cylinder 31, a hydraulic station 32, a first control valve 33 and a second control valve 34. The cylinder end of the hydraulic cylinder 31 is hinged to the coal bunker 100, and the piston rod end of the hydraulic cylinder 31 is hinged to the baffle 1. The oil end of the hydraulic station 32 is communicated with the rod chamber and the rodless chamber of the hydraulic cylinder 31 respectively. The first control valve 33 is arranged between the oil end of the hydraulic station 32 and the rod chamber of the hydraulic cylinder 31, and the second control valve 34 is arranged between the oil end of the hydraulic station 32 and the rodless chamber of the hydraulic cylinder 31. Wherein, the signal output end of the control module 4 is respectively connected with the signal input ends of the first control valve 33 and the second control valve 34. The control module 4 is used to control the actions of the first control valve 33 and the second control valve 34 to make the piston rod of the hydraulic cylinder 31 extend or retract.

[0035] It can be understood that, since the first control valve 33 is arranged between the oil end of the hydraulic station 32 and the rod chamber of the hydraulic cylinder 31, and the signal output end of the control module 4 is connected with the signal input end of the first control valve 33, the control module 4 can control the action of the first control valve 33. And, since the second control valve 34 is arranged between the oil end of the hydraulic station 32 and the rodless chamber of the hydraulic cylinder 31, and the signal output end of the control module 4 is connected with the signal input end of the second control valve 34, the control module 4 can control the action of the second control valve 34. Thus, through the cooperation of the first control valve 33 and the second control valve 34, the extension or retraction of the hydraulic cylinder 31 can be realized.

[0036] Since the cylinder end of the hydraulic cylinder 31 is hinged to the coal bunker 100, and the piston rod end of the hydraulic cylinder 31 is hinged to the baffle 1, when the piston rod of the hydraulic cylinder 31 extends, the opening of the inlet of the coal bunker 100 by the baffle 1 can be realized, so as to ensure that the coal material conveyed by the belt conveyor can stably enter the coal bunker 100. When the piston rod of the hydraulic cylinder 31 retracts, the closing of the inlet of the coal bunker 100 by the baffle 1 can be realized, so as to prevent people or materials from falling into the inlet of the coal bunker 100.

[0037] It should be noted that the hydraulic cylinder 31 is used to perform telescopic actions under the drive of the pressurized hydraulic fluid of the hydraulic station 32, so as to realize the opening and closing of the baffle 1 at the entrance of the coal bunker 100. The specific type of the hydraulic cylinder 31 can be set according to actual needs, and no limitation is imposed thereon.

[0038] The hydraulic station 32 is used to provide pressurized hydraulic fluid and recycle the hydraulic fluid. The specific type of the hydraulic station 32 can be set according to actual needs, and no limitation is imposed thereon. By way of example, the hydraulic station 32 includes an oil tank for recycling the hydraulic fluid, a hydraulic pump for transporting the hydraulic fluid, an overflow valve for protecting the hydraulic circuit, etc.

[0039] The first control valve 33 is used to control the on-off of the passage between the hydraulic fluid end of the hydraulic station 32 and the rod chamber of the hydraulic cylinder 31. Specifically, the first control valve 33 conducts the passage between the liquid outlet end of the hydraulic station 32 and the rod chamber of the hydraulic cylinder 31, and cuts off the passage between the liquid inlet end of the hydraulic station 32 and the rod chamber of the hydraulic cylinder 31, so as to realize the retraction action of the hydraulic cylinder 31. Or, the first control valve 33 conducts the passage between the liquid inlet end of the hydraulic station 32 and the rod chamber of the hydraulic cylinder 31, and cuts off the passage between the liquid outlet end of the hydraulic station 32 and the rod chamber of the hydraulic cylinder 31, so as to realize the extension action of the hydraulic cylinder 31. The specific type of the first control valve 33 can be set according to actual needs, and no limitation is imposed thereon.

[0040] The second control valve 34 is used to control the on-off of the passage between the hydraulic fluid end of the hydraulic station 32 and the rodless chamber of the hydraulic cylinder 31. Specifically, the second control valve 34 conducts the passage between the liquid outlet end of the hydraulic station 32 and the rodless chamber of the hydraulic cylinder 31, and cuts off the passage between the liquid inlet end of the hydraulic station 32 and the rodless chamber of the hydraulic cylinder 31, so as to realize the extension action of the hydraulic cylinder 31. Or, the second control valve 34 conducts the passage between the liquid inlet end of the hydraulic station 32 and the rodless chamber of the hydraulic cylinder 31, and cuts off the passage between the liquid outlet end of the hydraulic station 32 and the rodless chamber of the hydraulic cylinder 31, so as to realize the retraction action of the hydraulic cylinder 31. The specific type of the second control valve 34 can be set according to actual needs, and no limitation is imposed thereon.

[0041] Such as Figure 2As shown, in some embodiments, the driving device 3 further includes: a first pressure sensor 35 and a second pressure sensor 36. The detection end of the first pressure sensor 35 is arranged between the first control valve 33 and the rod chamber of the hydraulic cylinder 31, and the first pressure sensor 35 is used to detect the pressure in the rod chamber of the hydraulic cylinder 31. The detection end of the second pressure sensor 36 is arranged between the second control valve 34 and the rodless chamber of the hydraulic cylinder 31, and the second pressure sensor 36 is used to detect the pressure in the rodless chamber of the hydraulic cylinder 31. Wherein, the signal input ends of the control module 4 are respectively connected to the signal output ends of the first pressure sensor 35 and the second pressure sensor 36, and the control module 4 is used to control the first control valve 33 and the second control valve 34 to disconnect when the pressure in the rod chamber of the hydraulic cylinder 31 exceeds the first preset pressure and / or the pressure in the rodless chamber of the hydraulic cylinder 31 exceeds the second preset pressure.

[0042] It can be understood that, since the detection end of the first pressure sensor 35 is arranged between the first control valve 33 and the rod chamber of the hydraulic cylinder 31, the first pressure sensor 35 can detect the pressure in the rod chamber of the hydraulic cylinder 31. And, since the detection end of the second pressure sensor 36 is arranged between the second control valve 34 and the rodless chamber of the hydraulic cylinder 31, the second pressure sensor 36 can detect the pressure in the rodless chamber of the hydraulic cylinder 31. At the same time, since the signal input ends of the control module 4 are respectively connected to the signal output ends of the first pressure sensor 35 and the second pressure sensor 36, the control module 4 can obtain the pressure in the rod chamber of the hydraulic cylinder 31 by using the first pressure sensor 35 and obtain the pressure in the rodless chamber of the hydraulic cylinder 31 by using the second pressure sensor 36. Thus, when the pressure in the rod chamber of the hydraulic cylinder 31 exceeds the first preset pressure and / or the pressure in the rodless chamber of the hydraulic cylinder 31 exceeds the second preset pressure, the control module 4 controls the first control valve 33 and the second control valve 34 to disconnect, thereby avoiding damage to the hydraulic cylinder 31 caused by excessive oil pressure, and further realizing the safe operation of the baffle 1.

[0043] It should be noted that when problems such as jamming occur in the baffle 1, it will cause the chamber pressure of the hydraulic cylinder 31 to multiply. And the control module 4 stops the continuous action of the hydraulic cylinder 31 in a timely manner according to the chamber pressure of the hydraulic cylinder 31, which can avoid damage to the hydraulic cylinder 31 and further ensure the safe operation of the system.

[0044] Both the first pressure sensor 35 and the second pressure sensor 36 are pressure sensors, and the specific types of the first pressure sensor 35 and the second pressure sensor 36 can be set according to actual needs, and no limitation is made thereto.

[0045] Such as Figure 3As shown, in some embodiments, the system further includes: a speed detection unit 5 for detecting the conveying speed of the belt conveyor. The signal input end of the control module 4 is connected to the signal output end of the speed detection unit 5, and the control module 4 is used to control the opening angle of the baffle 1 according to the conveying speed of the belt conveyor.

[0046] It can be understood that since the signal input end of the control module 4 is connected to the signal output end of the speed detection unit 5, the control module 4 can obtain the conveying speed of the belt conveyor by using the speed detection unit 5. Thus, the control module 4 controls the opening angle of the baffle 1 according to the conveying speed of the belt conveyor, so as to realize the matching between the opening amplitude of the inlet of the coal bunker 100 and the throwing distance of the belt conveyor, and further ensure the efficient loading of coal materials.

[0047] It should be noted that the throwing distance of the belt conveyor is proportional to the conveying speed. That is to say, the faster the conveying speed of the belt conveyor, the farther the throwing distance; on the contrary, the slower the conveying speed of the belt conveyor, the closer the throwing distance.

[0048] In addition, the opening amplitude of the inlet of the coal bunker 100 is proportional to the opening angle of the baffle 1. That is to say, the larger the opening angle of the baffle 1, the larger the opening amplitude of the inlet of the coal bunker 100; on the contrary, the smaller the opening angle of the baffle 1, the smaller the opening amplitude of the inlet of the coal bunker 100.

[0049] Thus, when the conveying speed of the belt conveyor increases, it means that the throwing distance of the belt conveyor increases. To adapt to the farther throwing distance of the belt conveyor, it is necessary to increase the opening angle of the baffle 1 to increase the opening amplitude of the inlet of the coal bunker 100; on the contrary, when the conveying speed of the belt conveyor decreases, it means that the throwing distance of the belt conveyor decreases. To avoid the opening amplitude of the inlet of the coal bunker 100 being too large, the opening angle of the baffle 1 is reduced to reduce the opening amplitude of the inlet of the coal bunker 100, thereby reducing the falling risk.

[0050] The speed detection unit 5 is used to detect the conveying speed of the belt conveyor. The specific type of the speed detection unit 5 can be set according to actual needs and is not limited thereto. By way of example, the speed detection unit 5 can be an encoder, and the encoder is installed on the roller of the belt conveyor to obtain the conveying speed of the belt conveyor by using the encoder; the speed detection unit 5 can be a laser velocimeter, and the laser velocimeter is directed at the surface of the conveyor belt of the belt conveyor to measure the moving speed of the conveyor belt through the Doppler effect or the time difference method.

[0051] Such as Figure 3As shown, in some embodiments, the system further includes a position detection unit 6 configured to detect the position of the baffle 1. The signal input end of the control module 4 is connected to the signal output end of the position detection unit 6, and the control module 4 is configured to control the driving device 3 to act according to the position of the baffle 1 so that the baffle 1 rotates to a preset angle.

[0052] It can be understood that since the signal input end of the control module 4 is connected to the signal output end of the position detection unit 6, the control module 4 can obtain the position of the baffle 1 by using the position detection unit 6. Thus, the control module 4 controls the driving device 3 to act according to the position of the baffle 1 so that the baffle 1 rotates to a preset angle, thereby achieving precise control of the opening amplitude of the inlet of the coal bunker 100, and further minimizing the risk of falling while realizing efficient loading of coal materials.

[0053] It should be noted that the control module 4 controls the driving device 3 to act according to the position of the baffle 1, realizing closed-loop control, so as to be able to control the precise rotation of the baffle 1.

[0054] The position detection unit 6 is configured to detect the position of the baffle 1. The specific type of the position detection unit 6 can be set according to actual needs, and there is no limitation in this regard. By way of example, the position detection unit 6 can be a position sensor. The position detection unit 6 can detect the rotation angle of the rotating shaft of the baffle 1 to obtain the position of the baffle 1 according to the rotation angle of the rotating shaft, or can detect the extension distance of the hydraulic cylinder 31 to obtain the position of the baffle 1 according to the extension distance of the hydraulic cylinder 31.

[0055] As Figure 3 As shown, in some embodiments, the system further includes a spraying device 7. A plurality of spraying ends of the spraying device 7 are respectively arranged on the side surface of the baffle 1 away from the inlet of the coal bunker 100. The signal input end of the control module 4 is connected to the signal output end of the spraying device 7, and the control module 4 is configured to control the plurality of spraying ends of the spraying device 7 to spray respectively when the baffle 1 closes the inlet of the coal bunker 100.

[0056] It can be understood that since the signal input end of the control module 4 is connected to the signal output end of the spraying device 7, the control module 4 can control the plurality of spraying ends of the spraying device 7 to spray respectively. Thus, when the baffle 1 closes the inlet of the coal bunker 100, the control module 4 controls the plurality of spraying ends of the spraying device 7 to spray respectively, thereby realizing dust reduction at the inlet of the coal bunker 100 and avoiding affecting the quality of the coal materials inside the coal bunker 100.

[0057] It should be noted that the spray device 7 is used for spray dust reduction at the entrance of the coal bunker 100. The specific type of the spray device 7 can be set according to actual needs, and there is no limitation in this regard. By way of example, the spray device 7 may include a water tank for storing water, a water pump for conveying water, and a nozzle arranged on the baffle 1 and spraying water mist.

[0058] As Figure 3 shown, in some embodiments, the system further includes: a dust concentration detection unit 8, and the dust concentration detection unit 8 is used for detecting the dust concentration at the entrance of the coal bunker 100. Among them, the signal input end of the control module 4 is connected to the signal output end of the dust concentration detection unit 8, and the control module 4 is used for controlling the driving device 3 to act when the dust concentration at the entrance of the coal bunker 100 exceeds a preset concentration, so that the baffle 1 closes the entrance of the coal bunker 100.

[0059] It can be understood that since the signal input end of the control module 4 is connected to the signal output end of the dust concentration detection unit 8, the control module 4 can utilize the dust concentration detection unit 8 to obtain the dust concentration at the entrance of the coal bunker 100. Thus, when the dust concentration at the entrance of the coal bunker 100 exceeds the preset concentration, the control module 4 controls the driving device 3 to act, so that the baffle 1 closes the entrance of the coal bunker 100, thereby cooperating with the spray device 7 for spray dust reduction while stopping the continuous increase of the dust concentration.

[0060] It should be noted that when the baffle 1 closes the entrance of the coal bunker 100, the belt conveyor stops the conveying action.

[0061] The dust concentration detection unit 8 is used for detecting the dust concentration at the entrance of the coal bunker 100. The specific type of the dust concentration detection unit 8 can be set according to actual needs, and there is no limitation in this regard. By way of example, the dust concentration detection unit 8 may be a laser scattering type dust sensor, an optical scattering type dust sensor, etc.

[0062] As Figure 3 shown, in some embodiments, the system further includes: a ventilation device 9 and a temperature and humidity detection unit 10. The ventilation end of the ventilation device 9 penetrates through the baffle 1 and is oppositely arranged to the entrance of the coal bunker 100. The temperature and humidity detection unit 10 is used for detecting the temperature and humidity at the entrance of the coal bunker 100. Among them, the signal input end of the control module 4 is connected to the signal output end of the temperature and humidity detection unit 10, and the signal output end of the control module 4 is connected to the signal input end of the ventilation device 9. The control module 4 is used for controlling the ventilation end of the ventilation device 9 to ventilate when the temperature at the entrance of the coal bunker 100 is greater than a preset temperature and / or the humidity at the entrance of the coal bunker 100 is greater than a preset humidity.

[0063] It can be understood that since the signal input end of the control module 4 is connected to the signal output end of the temperature and humidity detection unit 10, and the signal output end of the control module 4 is connected to the signal input end of the ventilation device 9, the control module 4 can obtain the temperature and humidity at the entrance of the coal bunker 100 by using the temperature and humidity detection unit 10, and can control the ventilation of the ventilation end of the ventilation device 9. Thus, when the temperature at the entrance of the coal bunker 100 is greater than the preset temperature and / or the humidity at the entrance of the coal bunker 100 is greater than the preset humidity, the control module 4 controls the ventilation end of the ventilation device 9 to ventilate, so as to effectively reduce the temperature and / or humidity at the entrance of the coal bunker 100 by ventilation, and further ensure the safe loading of the coal material.

[0064] It should be noted that the ventilation device 9 is used for ventilation at the entrance of the coal bunker 100, and the specific type of the ventilation device 9 can be set according to actual needs, and no limitation is imposed thereon. By way of example, the ventilation device 9 can be a fan for forming pressured air, as well as a hose and a nozzle arranged on the baffle 1.
