Abstract
Description
Technical Field
[0001] This application relates to the technical field of controllers, and more particularly, to an electrical integrated controller for thin coal seam mining. Background Art
[0002] A controller is an indispensable electronic device in an automation system. It receives input signals from sensors or other devices and achieves precise control of the controlled object. Controller heating is a common problem. Most existing controllers dissipate heat by opening heat dissipation grilles on the outer wall of the device and cooperating with a fan. Most existing controllers direct the cooling fan towards the circuit structure with severe heat generation to ensure heat dissipation. However, in the mining of thin coal seams, due to limited working space, the controller needs to be controlled within a certain size, and at the same time, it is necessary to prevent the fan and the heat dissipation grille from being blocked.
[0003] Moreover, the working environment of the controllers used in coal mining is relatively harsh, facing the impacts of dust, high temperature, high humidity, etc. After coal dust enters the controller, it is easy to adsorb moisture and form electrolytes, which easily affect the circuit stability.
[0004] Therefore, an electrical integrated controller for thin coal seam mining is needed to solve the above problems. Summary of the Invention
[0005] The content part of this application is used to briefly introduce concepts, which will be described in detail in the subsequent detailed implementation part. The content part of this application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.
[0006] To solve the technical problems mentioned in the above background art section, some embodiments of the present application provide an electrical appliance integrated controller for thin coal seam mining, including: a housing, on one side of which there is a vertically extending air inlet groove, and on the opposite side of the air inlet groove of the housing there is an air outlet groove; a filter plate, which is used to form the housing, the air inlet groove is arranged on the filter plate, and a filter screen is arranged in the air inlet groove for filtering dust; a heat dissipation plate, which is fixedly arranged in the housing; a mounting plate, which is fixed in the housing and arranged parallel to the heat dissipation plate, and is located on the side of the heat dissipation plate close to the air inlet groove; wherein, the heat dissipation plate and the mounting plate divide the inner cavity of the housing into an adjacent installation space, a heat dissipation space, and a back-blowing space in sequence, the air inlet groove is located on one side of the back-blowing space, and the air outlet groove is located on one side of the installation space; a heat dissipation fan, which is fixed on the mounting plate and is used to blow the air in the back-blowing space into the heat dissipation space; a through opening, which is opened on the heat dissipation plate and is used to discharge the air that the heat dissipation fan enters into the heat dissipation space into the installation space; a circuit board box, which is fixedly installed in the installation space, and a heat conduction block is connected between the circuit board box and the heat dissipation plate, and heat dissipation fins extending horizontally are arranged on the heat dissipation plate; two partition plates, which are slidably arranged in the back-blowing space and are used to divide the back-blowing space into an air inlet area and back-blowing areas located on both sides of the air inlet area, and the air inlet end of the heat dissipation fan faces the air inlet area; an air guide cylinder, one end of which is connected to the installation space and the other end extends to the back-flushing area of the back-blowing space, and is used to guide the air flow in the installation space or the heat dissipation space to the back-blowing space.
[0007] By providing the heat dissipation plate and the mounting plate, when rapid heat dissipation is required, the external cold air can be directly sucked into the installation space through the heat dissipation fan to ensure the heat dissipation effect. When the dust and moisture in the air are relatively high, the cold air is discharged into the heat dissipation space through the heat dissipation fan, and heat dissipation is carried out through the heat dissipation fins. At the same time, by providing the partition plates, when the filter plate adheres to more dust, the air can be blown out in the reverse direction to avoid dust clogging the filter plate.
[0008] Further, a first air inlet located in the installation space, a second air inlet located in the heat dissipation space, a first air outlet and a second air outlet located in the back-blowing space are opened on the air guide cylinder; a shielding plate for blocking the through opening is slidably arranged on the heat dissipation plate; a right-angle plate for controlling the opening and closing of the first air inlet and the second air inlet is slidably connected to the heat dissipation plate; the right-angle plate includes a first plate portion for controlling the opening and closing of the first air inlet and a second plate portion for controlling the opening and closing of the second air inlet. By sliding the right-angle plate, the first air inlet is opened and the second air inlet is closed, or the second air inlet is opened and the first air inlet is closed.
[0009] With the provided baffle and right-angled plate, when the baffle closes the through-port, the right-angled plate closes the first air inlet and opens the second air inlet. The cold air inhaled by the cooling fan flows within the heat dissipation space and will not be blown into the installation space, preventing dust and the like from entering the installation space and affecting the circuit. Since the air flows along the heat dissipation fins within the heat dissipation space, the heat dissipation of the heat dissipation fins is ensured.
[0010] Furthermore, a sliding baffle for controlling the opening and closing of the first air outlet is slidably connected within the air guide cylinder. A pressure plate is hermetically slidably connected within the air guide cylinder. A first spring is connected between the pressure plate and the sliding baffle. A second spring is connected between the sliding baffle and the inner wall of the air guide cylinder. A limiting member is slidably arranged on the air guide cylinder. The limiting member has a first convex head and a second convex head extending into the air guide cylinder. Among them, a groove for the first convex head to be embedded is formed on the sliding baffle. An inclined surface in contact with the sliding baffle is provided on the first convex head. By pushing the inclined surface with the sliding baffle, the limiting member moves, the first convex head disengages from the groove, and a third spring is connected between the limiting member and the air guide cylinder.
[0011] With the provided sliding baffle and pressure plate, after sufficient air pressure is generated within the air guide cylinder, the pressure plate will contact the second convex head. Under the action of the first spring, the sliding baffle is quickly opened, and the air pressure within the air guide cylinder is quickly released, causing the filter plate within the backflush area to be backflushed. When the air pressure is released, under the action of the second spring, the sliding baffle continues to close the first air outlet. Thus, reciprocatingly, the filter plate is pulsatingly backflushed to ensure the dust removal effect.
[0012] Furthermore, the sliding baffle is fixedly connected with a moving rod that passes through the air guide cylinder and the filter plate. One end of the moving rod is fixedly connected with a knocking plate for knocking the filter plate.
[0013] With the provided moving rod and knocking plate, after the air pressure in the air guide cylinder is released, under the action of the second spring, the pressure plate quickly rebounds, thereby driving the moving rod and the knocking plate to move, knocking the filter plate, causing the filter plate to vibrate, and shaking off the blocked dust.
[0014] Furthermore, a reset spring is connected between the heat dissipation plate and the baffle, and a connecting rod is connected between the baffle and the right-angled plate.
[0015] With the reset spring, when the partition no longer pushes the baffle, the baffle can be reset. After the partition moves to the closest position, the partition will push the baffle to block the through-port. At this time, under the action of the connecting rod, the right-angled plate also closes the first air inlet and opens the second air inlet. At this time, the cold air no longer enters the installation space.
[0016] Further, a bent rod with one end fixedly connected to the shielding plate is hermetically and slidably arranged on the mounting plate. One end of the bent rod has an abutting portion protruding from the mounting plate, and the abutting portion is used to contact the partition plate.
[0017] Through the provided bent rod, when the partition plate moves to the closest position, the shielding plate is driven to close the through-port by pushing the abutting portion.
[0018] Further, one end of the heat dissipation fin penetrates through the mounting plate, and at the same time, a slot for the heat dissipation fin to pass through is formed on the partition plate.
[0019] By forming a slot on the partition plate, when the partition plate moves, the dust on the heat dissipation fin can be scraped off.
[0020] Further, the second air inlet and the first air outlet are opposite to the heat dissipation fins.
[0021] When the first air inlet is closed, the air first flows along the heat dissipation fins in the heat dissipation space, is guided by the air guide cylinder, then flows out from the first air outlet, and continues to flow along the heat dissipation fins for sufficient heat dissipation.
[0022] Further, a plug plate for closing the air outlet groove is slidably connected in the outer shell. A first driving member is fixedly arranged in the outer shell to drive the plug plate to move and control the opening and closing of the air outlet groove; a second driving member is also arranged in the outer shell to control the movement of the partition plate.
[0023] When it is necessary to perform backwashing and dust removal on the partition plate, the air outlet groove is closed by the first driving member to prevent air from flowing out of the air outlet groove and ensure the backwashing air flow.
[0024] Further, a pressure sensor is fixedly arranged in the air inlet area within the backwashing space.
[0025] Through the provided pressure sensor, when the air pressure in the air inlet area is lower than the set threshold value, the filter plate is blocked.
[0026] The beneficial effects of the present application are as follows:
[0027] 1. Through the provided heat dissipation plate and mounting plate, when rapid heat dissipation is required, the external cold air can be directly sucked into the mounting space by the heat dissipation fan to ensure the heat dissipation effect. When the dust and moisture in the air are relatively high, the cold air is discharged into the heat dissipation space by the heat dissipation fan and dissipated by the heat dissipation fins. At the same time, through the provided partition plate, when the filter plate adheres to more dust, the air can be blown out in the reverse direction to prevent the filter plate from being blocked by dust.
[0028] 2. Through the provided baffle and right-angle plate, when the baffle closes the through-port, the right-angle plate closes the first air inlet and opens the second air inlet. The cold air inhaled by the cooling fan flows within the cooling space and will not be blown into the installation space, preventing dust and the like from entering the installation space and affecting the circuit. Since the air flows along the cooling fins within the cooling space, the heat dissipation of the cooling fins is ensured.
[0029] 3. Through the provided sliding baffle and air pressure plate, after sufficient air pressure is generated within the air guide cylinder, the air pressure plate will contact the second convex head. Under the action of the first spring, the sliding baffle quickly opens, and the air pressure within the air guide cylinder is quickly released, causing the filter plate within the backwash area to be backwashed. When the air pressure is released, under the action of the second spring, the sliding baffle continues to close the first air outlet. This process repeats, performing a pulsating backwash on the filter plate to ensure the dust removal effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
[0048] Referring to Figure 1-8 , an electrical comprehensive controller for thin coal seam mining, comprising: a housing 10, a filter plate 13, an air inlet groove 11, an air outlet groove 12, a heat dissipation plate 14, a mounting plate 15, a heat dissipation fan 16, a through port 17, a circuit board box 18, a partition plate 19, and an air guide cylinder 20. The filter plate 13 is used to form a side plate of the housing 10. The air inlet groove 11 is opened on the filter plate 13 and extends vertically. A filter screen is arranged in the air inlet groove 11 for filtering dust. The air outlet groove 12 and the air inlet groove 11 are arranged on both sides in the length direction of the housing and on both sides of the circuit board box 18 to adapt to the relatively small height of the working space in the thin coal seam. It avoids the air inlet groove 11 and the air outlet groove 12 from being blocked.
[0049] Since in the dusty environment of coal mines, dust is likely to block the filter plate 13, affecting the heat dissipation effect, and it is difficult to remove the dust blocked in the gaps by brushing, the following solution is adopted.
[0050] In one embodiment, a heat dissipation plate 14 and a mounting plate 15 are fixedly arranged inside the housing 10. The mounting plate 15 is arranged parallel to the heat dissipation plate 14. The mounting plate 15 is located on the side of the heat dissipation plate 14 close to the air inlet groove 11, so that air can sequentially pass through the air inlet groove 11, the mounting plate 15, the heat dissipation plate 14, and the air outlet groove 12. The heat dissipation plate 14 and the mounting plate 15 divide the inner cavity of the housing 10 into an adjacent mounting space 21, a heat dissipation space 22, and a back blowing space 23 in sequence. The air inlet groove 11 is located on one side of the back blowing space 23, and the air outlet groove 12 is located on one side of the mounting space 21. The heat dissipation fan 16 is fixed on the mounting plate 15 and is used to blow the air in the back blowing space 23 into the heat dissipation space 22, and the outside cold air enters the back blowing space 23 from the air inlet groove 11. The through port 17 is opened on the heat dissipation plate 14 and is used to discharge the air that the heat dissipation fan 16 enters into the heat dissipation space 22 into the mounting space 21. The circuit board box 18 is located opposite to the through port 17. There are two partition plates 19, which are hermetically and slidably arranged in the back blowing space 23 and are used to divide the back blowing space 23 into an air inlet area and back blowing areas located on both sides of the air inlet area. The air inlet end of the heat dissipation fan 16 faces the air inlet area. Among them, there is a second driving member in the housing 10 for driving the partition plates 19. The second driving member includes a fixedly arranged motor 24. The power output end of the motor 24 is fixedly connected with a bidirectional screw rod 25. Two sections with different rotation directions of the bidirectional screw rod 25 are respectively threadedly connected with the two partition plates 19. By rotating the bidirectional screw rod 25, the two partition plates 19 move towards or away from each other. One end of the air guide cylinder 20 is connected to the mounting space 21, and the other end extends to the back flushing area of the back blowing space 23 and is used to guide the air flow in the mounting space 21 or the heat dissipation space 22 to the back blowing space 23. When it is necessary to remove the dust on the filter plate 13, first close the air outlet groove 12. At this time, the air entering the mounting space 21 from the air inlet area enters the air guide cylinder 20 from the first air inlet 26 and is guided to the back flushing area, and the part of the filter plate 13 located in the back flushing area is back flushed, so that the blocked dust is flushed out. By adjusting the distance between the two partition plates 19, the back flushing area is adjusted. A pressure sensor is fixedly arranged in the air inlet area in the back flushing space. When the filter plate 13 is blocked, air cannot enter the back flushing space. At this time, the air pressure in the back flushing space decreases. When the air pressure is less than a threshold value, it is necessary to remove the dust on the filter plate 13.
[0051] In another embodiment, to ensure the dust removal effect, a first air inlet 26 located in the mounting space 21, a second air inlet 27 located in the heat dissipation space 22, a first air outlet 28 and a second air outlet 29 located in the back blowing space 23 are opened on the air guide cylinder 20.
[0052] A sliding baffle 30 for controlling the opening and closing of the first air outlet 28 is slidably connected inside the air guide cylinder 20. A pressure plate 31 is hermetically slidably connected inside the air guide cylinder 20. A non-compressible first spring 32 is connected between the pressure plate 31 and the sliding baffle 30. A second spring 33 is connected between the sliding baffle 30 and the inner wall of the air guide cylinder 20. A limiting member 34 is slidably arranged on the air guide cylinder 20. The limiting member 34 has a first convex head 35 and a second convex head 36 extending into the air guide cylinder 20. Among them, a groove 37 for the first convex head 35 to be embedded is formed on the sliding baffle 30. An inclined surface in contact with the sliding baffle 30 is arranged on the first convex head 35. The limiting member 34 moves by pushing the inclined surface through the sliding baffle 30, the first convex head 35 disengages from the groove 37, and a third spring 38 is connected between the limiting member 34 and the air guide cylinder 20. By arranging the sliding baffle 30 and the pressure plate 31, after sufficient air pressure is generated inside the air guide cylinder 20, the pressure plate 31 will contact the second convex head 36. Under the action of the first spring 32, the sliding baffle 30 is quickly opened, and the air pressure inside the air guide cylinder 20 is quickly released, so that part of the filter plate 13 in the backflush area is backflushed. When the air pressure is released, under the action of the second spring 33, the sliding baffle 30 continues to close the first air outlet 28. Thus, reciprocatingly, the filter plate 13 is pulsatingly backflushed to ensure the dust removal effect.
[0053] In another embodiment, the sliding baffle 30 is fixedly connected with a moving rod 39 that penetrates through the air guide cylinder 20 and the filter plate 13. One end of the moving rod 39 is fixedly connected with a knocking plate 40 for knocking the filter plate 13. By arranging the moving rod 39 and the knocking plate 40, when the air pressure in the air guide cylinder 20 is released, under the action of the second spring 33, the pressure plate 31 quickly rebounds, thereby driving the moving rod 39 and the knocking plate 40 to move, knocking the filter plate 13, so that the filter plate 13 vibrates and shakes off the blocked dust.
[0054] To close the air outlet groove 12 and obtain sufficient backflush air pressure, it is necessary to close the air outlet groove 12. A plug plate 41 for closing the air outlet groove 12 is slidably connected inside the housing 10. A first driving member is arranged inside the housing 10. The first driving member includes a cylinder 42 fixedly connected inside the housing 10. One end of the piston rod of the cylinder 42 is fixedly connected with the plug plate 41, so that the plug plate 41 can move to control the opening and closing of the air outlet groove 12.
[0055] During the coal mining process, there will be a situation where the dust content in the air is relatively high. When the cooling fan 16 is used to dissipate heat inside the housing 10, it is inevitable that dust will enter the housing 10. Therefore, when there is too much dust, it is necessary to avoid air exchange between the installation space 21 and the outside world. Therefore, the following solution is adopted.
[0056] The circuit board box 18 is fixedly installed in the installation space 21, and a heat conduction block 43 is connected between the circuit board box 18 and the heat dissipation plate 14. The heat dissipation plate 14 is provided with laterally extending heat dissipation fins 44. One end of the heat dissipation fin passes through the mounting plate 15, and at the same time, a slot for the heat dissipation fin to pass through is formed in the partition plate 19. A right-angled plate 45 for controlling the opening and closing of the first air inlet 26 and the second air inlet 27 is slidably connected to the heat dissipation plate 14. The right-angled plate 45 includes a first plate portion 46 for controlling the opening and closing of the first air inlet 26 and a second plate portion 47 for controlling the opening and closing of the second air inlet 27. By sliding the right-angled plate 45, the first air inlet 26 is opened and the second air inlet 27 is closed, or the second air inlet 27 is opened and the first air inlet 26 is closed. A magnetic ring on the adsorption air guide cylinder 20 is provided on the second plate portion 47, and a corresponding magnetic ring is provided on the air guide cylinder 20. The magnetic rings attract each other to prevent the air pressure in the air guide cylinder 20 from pushing the right-angled plate 45. A shielding plate 48 is also slidably connected to the heat dissipation plate 14. A return spring 52 is connected between the heat dissipation plate 14 and the shielding plate 48, and a connecting rod 51 is connected between the shielding plate 48 and the right-angled plate 45. A shielding plate 48 for blocking the through port 17 is slidably arranged on the heat dissipation plate 14. When the shielding plate 48 blocks the through port 17, external air cannot enter the installation space 21, and at this time, heat dissipation is carried out through the heat dissipation fins 44. Since there is more external dust at this time, it is necessary to reduce the intake of air to avoid dust entering. A bent rod 49 with one end fixedly connected to the shielding plate 48 is hermetically slidably arranged on the mounting plate 15. One end of the bent rod 49 has an abutting portion 50 protruding from the mounting plate 15, and the abutting portion 50 is used for contacting the partition plate 19. When the two partition plates 19 are closest to each other, the air intake area on the filter plate 13 is the smallest. At this time, the partition plate 19 pushes the bent rod through the abutting portion 50, so that the shielding plate 48 closes the through port 17, and at the same time, the right-angled plate 45 can close the first air inlet 26 and open the second air inlet 27.
[0057] Working or installation process:
[0058] 1. When rapid heat dissipation is required, the shielding plate 48 does not block the through port 17, and the two partition plates 19 are farthest apart. At this time, the air intake area is the largest, ensuring the air intake volume. The plugging plate 41 plugs the air outlet groove 12, and at the same time, the partition plate 19 also blocks the position of the first air outlet 28 of the air guide cylinder 20. At this time, all the air inhaled by the heat dissipation fan 16 is discharged into the installation space 21 and discharged through the air outlet groove 12, and the external cold air directly dissipates heat to the installation space 21 to ensure the heat dissipation effect;
[0059] 2. When the air pressure sensor detects that the air pressure is less than a threshold value, the filter plate 13 is blocked. At this time, the cylinder 42 is activated to close the air outlet groove 12 through the blocking plate 41. The motor 24 is started to drive the two partition plates 19 to move towards each other. At this time, the partition plates 19 no longer block the position of the first air outlet 28. Since the air outlet groove 12 is closed, the air entering the installation space 21 enters the air guide cylinder 20 through the first air inlet 26. Under the action of the air pressure, the air pressure plate 31 is driven to move, and the limiting member 34 is pushed to move through the inclined surface on the second convex head 36. Since the first spring 32 is stretched and the second spring 33 is compressed when the air pressure plate 31 moves, when the limiting member 34 is pushed and no longer limits the sliding baffle 30, it moves quickly under the action of the first spring 32 to open the first air outlet 28, and the air flow is discharged into the backwashing area for backwashing and dust removal; the distance between the two partition plates 19 is adjusted by controlling the motor 24 to adjust the dust removal range.
[0060] 3. When the dust content in the air is too high, it is necessary to prevent air from entering the installation space 21. By controlling the motor 24, the two partition plates 19 are made to be closest to each other. At this time, the intake area is the smallest. At this time, the partition plates 19 will push the shielding plate 48 to move to close the through port 17, and drive the right-angled plate 45 to move to close the first air inlet 26 and open the second air inlet 27. At this time, the air entering the heat dissipation space 22 will flow along the heat dissipation fins 44 and enter the second air inlet 27 and is discharged from the first air outlet 28 of the air guide cylinder 20. Heat dissipation is carried out through the heat dissipation fins 44, and a positive pressure can be continuously generated in the backwashing area to reduce the entry of dust.
[0061] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features having similar functions disclosed in the embodiments of the present disclosure.
