[0029] The present invention provides the following embodiments

[0030] Example 1

[0031] The embodiment of the present invention provides a dustproof and high temperature proof junction box, such as Figure 1-Figure 3 As shown, it includes a box body 1, the top and bottom of the front side of the box body 1 are movably connected to a box door 2 through hinges, a heat dissipation mechanism 3 is arranged on one side wall of the box body 1, a dustproof mechanism 4 is arranged on the other side wall of the box body 1, a dust removal mechanism 46 is arranged at the bottom of the box body 1, and the junction box body 8 is arranged on the dust removal mechanism 46.

[0032] Preferably, a sealing strip 5 is fixedly installed on the circumferential side of the back side of the box door 2, and a sealing groove 6 used in conjunction with the sealing strip 5 is embedded on the circumferential side of the front side of the box body 1, a plurality of junction boxes 7 are arranged inside the junction box body 8, and a plurality of heat dissipation holes 9 are opened on the left and right side walls of the junction box body 8.

[0033] Preferably, the dustproof includes a dust box 10, the left side wall of the dust box 10 is fixedly mounted on the outer wall on the right side of the box body 1, and the air outlet on the right side wall of the box body 1 is connected to the air inlet on the left side wall of the dust box 10, the dust box 10 is divided into a cavity 12 and a cavity 2 13 by a partition 11, a drive motor 14 is fixedly mounted on the bottom of the cavity 12, a drive shaft 15 is fixedly connected to the output shaft of the drive motor 14, and two support plates 16 are fixedly mounted on the right inner wall of the cavity 12 at a distance from each other. The upper end of the driving shaft 15 rotates through the two supporting plates 16 and the partition 11 in sequence, the upper end of the driving shaft 15 is fixedly installed with a driving pulley 17 in the cavity 13, and the cam 18 is fixedly installed in the middle of the driving shaft 15. The upper and lower ends of the slide plate 19 are slidably connected to the grooves 20 at the top and bottom of the cavity 12. The right side wall of the slide plate 19 is rollingly connected to the cam 18, and the left side wall of the slide plate 19 is fixedly connected to the inner wall of the cavity 12 through a plurality of springs 21.

[0034] Preferably, a dust collecting plate 22 is embedded in the left side wall of the skateboard 19, and a plurality of through holes 23 are opened on the skateboard 19 from left to right, the exhaust fan 24 is fixedly installed at the air outlet of the dust collecting box 10, the upper end of the rotating shaft 25 is rotatably connected to the top of the inner wall of the box body 1, and a driven pulley 26 is fixedly installed in the middle of the rotating shaft 25, the driven pulley 26 is connected to the driving pulley 17 through a driving belt 27, and the lower end of the rotating shaft 25 rotates to the top of the junction box body 8 and a cooling fan 28 is fixedly installed.

[0035] The working principle and beneficial effects of the above technical solution are:

[0036] The above-mentioned dustproof and high-temperature proof junction box is mainly composed of a box body 1, a box door 2, a dustproof mechanism 4, a heat dissipation mechanism 3 and a dust removal mechanism 46. The dust attached to the junction box body 8 is blown off by the dustproof mechanism 4, and the dust scattered inside the junction box is collected, thereby ensuring a dust-free environment inside the junction box. At the same time, the heat dissipation mechanism 3 can drive the fan to rotate to blow heat inside the junction box, and can continuously change the angle of blowing heat dissipation, thereby making the heat dissipation more comprehensive and more effective, avoiding safety hazards such as line aging and damage caused by high temperature, and greatly improving the service life of the junction box. By using the sealing groove 6 embedded on the side of the front of the box body 1 in conjunction with the sealing strip 5, the junction box can be fully sealed to prevent dust from entering; at the same time, a number of junction boxes 7 are arranged inside the junction box body 8 to avoid internal damage caused by multiple unwinding and wiring, and can be quickly replaced during maintenance, which not only saves maintenance time, but also reduces the difficulty of maintenance work, and effectively increases the reliability of the use of the junction box; secondly, a number of heat dissipation holes 9 arranged on the two side walls of the junction box body 8 can dissipate heat inside it as soon as possible, avoiding untimely heat dissipation inside the junction box, resulting in excessive internal temperature and safety hazards such as line aging and damage.

[0037] When the dust-proof mechanism 4 set up above starts to work, the driving motor 14 is started to drive the driving shaft 15 fixedly connected to the output shaft of the driving motor 14 to rotate synchronously, so that the cam 18 fixedly connected to the driving shaft 15 and the driving pulley 17 rotate synchronously on the two supporting plates 16, and the driving pulley 17 rotates, so that the driven pulley 26 connected to the driving belt 27 rotates synchronously, and the rotating shaft 25 fixedly connected to the driven pulley 26 rotates synchronously along the top of the box body 1, and the cooling fan 28 fixedly installed at the lower end of the rotating shaft 25 rotates, so as to blow air into the junction box body 8 to complete the heat dissipation, which not only realizes the effective reduction of the internal temperature of the junction box body 8, but also blows off the dust attached to the inside of the junction box body 8, so as to cooperate with the dust-proof mechanism 4 to collect dust; at the same time, the rotation of the cam 18 drives the slide plate 19 to slide left and right along the upper and lower inner walls of the cavity 12, and at the same time, a plurality of springs 1 The elastic force of 21 can ensure that the slide plate 19 is reset after moving to the left, so that the slide plate 19 can realize reciprocating motion. When the dust inside the junction box starts to be collected, the exhaust fan 24 is operated, so that the dust inside the junction box enters the dust box 10 through the air outlet on its right side wall. The dust entering the dust box 10 will pass through the dust collection plate 22 under the action of the exhaust fan 24, so that all the dust carried in the air is collected on the dust collection plate 22. At the same time, the reciprocating movement of the slide plate 19 also vibrates the dust attached to the dust collection plate 22, so that the dust falls down to maintain the dust collection efficiency of the dust collection plate 22. After the dustproof mechanism 4 has worked for a period of time, the dust collection box 10 can be opened to clean the dust inside. The dustproof mechanism 4 not only effectively reduces the temperature inside the junction box body, but also timely and effectively cleans and collects the dust attached to the inside of the junction box body 8, thereby ensuring a dust-free environment inside the junction box.

[0038] Example 2

[0039] On the basis of Example 1, Figure 2 , Figure 4-Figure 5As shown, the heat dissipation mechanism 3 includes a heat dissipation box 29, the right side wall of the heat dissipation box 29 is fixedly mounted on the outer wall on the left side of the box body 1, and the air outlet on the right side of the heat dissipation box 29 is connected to the air inlet on the left side wall of the box body 1, and a filter screen 30 is embedded on the left side wall of the heat dissipation box 29, one end of two mounting shafts 31 is fixedly mounted on the left side inner wall of the heat dissipation box 29 with a distance between them, and the other ends of the two mounting shafts 31 are respectively fixedly mounted with cooling fans 32, and the two mounting shafts 31 A driven pulley 33 is fixedly installed on it, and a driving motor 34 is fixedly installed on the outer wall of the heat dissipation box 29 through a fixing seat 35. A transmission shaft 36 is fixedly connected to the output shaft of the driving motor 34. The right end of the transmission shaft 36 rotates and passes through the bottom of the left side wall of the box body 1. A driving pulley 37 is fixedly installed on the transmission shaft 36, and the driving pulley 37 is connected to the two driven pulleys 33 through a driving belt 38. A worm 39 is fixedly connected to the right end of the transmission shaft 36.

[0040] Preferably, it also includes a fixing rod 40, which is fixedly mounted on the inner wall on the left side of the box body 1, and a worm gear 41 is rotatably connected to the fixing rod 40, and the worm gear 41 is meshed with the worm 39, and a mounting bracket 42 is fixedly mounted on the inner wall on the left side of the box body 1, and a plurality of guide plates 43 are hingedly mounted on the right side wall of the mounting bracket 42 at upper and lower intervals, and the middle part of the guide plate 43 is hinged by a connecting rod 44, and the lower end of the connecting rod 44 is hinged to a hinge rod 45, and the lower end of the hinge rod 45 is hinged to a position away from the center of the worm gear 41.

[0041] Preferably, the dust removal mechanism 46 includes a drive box 47, the drive box 47 is fixedly mounted on the bottom of the box body 1, the servo motor 48 is fixedly mounted on the right side wall of the drive box 47, the output shaft of the servo motor 48 is fixedly connected with a drive shaft 2 49, the left end of the drive shaft 2 49 is rotatably connected to the inner wall of the left side of the drive box 47, two bevel gears 1 50 are fixedly connected to the drive shaft 2 49 at a symmetrical interval, and the upper ends of the two threaded rods 51 rotate symmetrically along the junction box body 8 Connected to the top of the box body 1, the lower ends of the two threaded rods 51 rotate and pass through the top of the drive box 47 and are fixedly connected with bevel gear 2 52 respectively, the bevel gear 2 52 is meshed with bevel gear 1 50, two threaded sleeves 53 are respectively threadedly connected to the threaded rods 51, and a cleaning plate 54 is fixedly installed on the threaded sleeves 53. Two control switches 55 are respectively fixedly installed on the top of the inner wall of the box body 1 and one side of the top of the drive box 47, and the two control switches 55 are electrically connected to the servo motor 48.

[0042] Preferably, it also includes a dustproof component 56, which is arranged on the top of the driving box 47, and two fixed plates 57 are fixedly installed on the top of the driving box 47 at a distance from each other, and both ends of the support shaft 58 are respectively fixedly connected to the inner walls of the two fixed plates 57, and a plurality of dustproof baffles 59 are rotatably connected to the support shaft 58 at a distance.

[0043] The working principle and beneficial effects of the above technical solution are:

[0044] When the heat dissipation mechanism 3 is set up, the driving motor 14 is started, and the transmission shaft 36 fixedly connected to the output shaft of the driving motor 14 is driven to rotate synchronously, so that the driving pulley 2 37 fixedly connected to the transmission shaft 36 can rotate, and the two driven pulleys 2 connected by the driving belt 2 38 rotate on the installation shaft 31 under the action of the driving pulley 2 37, so that the heat dissipation fan 2 32 fixedly installed on the installation shaft 31 rotates synchronously. At this time, the outside air is continuously filtered through the filter screen 30 embedded in the heat dissipation side wall, and then transported to the inside of the box body 1 through the air outlet on the right side wall of the heat dissipation box 29. At the same time, the rotation of the transmission shaft 36 drives the fixedly connected worm 39 to rotate in the box body 1, and the fixed rod The worm wheel 41 connected to the worm 39 is meshed with the worm 39 for transmission, so that the worm wheel 41 can rotate on the fixed rod 40. As the worm wheel 41 continues to rotate, the hinged rod 45 hinged at a position far away from the center of the worm wheel 41 drives the connecting rod 44 to move up and down. At the same time, the mounting bracket 42 mounts a plurality of guide plates 43 at the air inlet of the box body 1. The hinged rod 45 drives the connecting rod 44 to swing up and down along the mounting bracket 42, so that the air outlet at the air inlet of the box body 1 is changed in the blowing direction by the plurality of guide plates 43. As the plurality of guide plates 43 continuously change the blowing direction, the angle of the blowing and heat dissipation is continuously changed, so that the heat dissipation inside the junction box can be made more comprehensive and the effect is better.

[0045] The dust removal mechanism 46 provided at the bottom of the box body 1 cooperates with the dust suction mechanism to effectively remove dust attached to the surface of the junction box body 8 and the heat dissipation holes 9. When the dust removal mechanism 46 starts to work, the servo motor 48 fixedly installed in the drive box 47 starts to work, so that the drive shaft 2 49 fixedly connected to the output shaft of the servo motor 48 rotates synchronously, and the two bevel gears 1 50 fixedly connected to the drive shaft 2 49 at a symmetrical interval on the left and right also rotate. The two bevel gears 1 50 correspond to the two bevel gears 2 52 fixedly connected to the two threaded rods 51 in a one-to-one manner to achieve meshing transmission, so that the two threaded rods 51 rotate along the top of the box body 1. At the same time, under the forward and reverse drive of the servo motor 48, the two threaded sleeves 53 threadedly connected to the two threaded rods 51 move up and down with the rotation of the threaded rods 51, so that the fixed installation The cleaning plate 54 on the threaded sleeve 53 moves up and down along the side wall of the junction box body 8, thereby completing the effective removal of dust attached to the side wall of the junction box body 8, and also promptly removing dust from the several heat dissipation holes 9 embedded on the two side walls of the junction box body 8, to avoid causing poor ventilation of the several heat dissipation holes 9, thereby affecting the heat dissipation efficiency of the junction box body 8. As the threaded sleeve 53 moves upward or downward along the threaded rod 51, when the threaded sleeve 53 contacts the control switch 55 located at the top of the inner wall of the box body 1 and the top of the drive box 47, the control opening controls the servo motor 48 to rotate in the opposite direction to complete the multiple cleaning of the junction box body 8 by the dust removal mechanism 46. The cleaned and fallen dust is collected by the dustproof mechanism 4. The above mechanism not only improves the heat dissipation efficiency of the junction box body 8, but also maintains the dust-free environment inside the junction box, and has high reliability.

[0046] By setting up the dustproof component 56, when it is necessary to wire the inside of the junction box, it is only necessary to turn and rotate several baffles connected to the support shaft 58 to complete the wiring operation. At the same time, when it is not necessary to wire the inside of the box body 1, lowering the dustproof baffle 59 can effectively prevent external dust from entering the inside of the junction box through the wiring hole and causing pollution inside the junction box.

[0052] The working principle and beneficial effects of the above technical solution are:

[0053] The support mechanism 60 provided at the bottom of the box body 1 can not only prevent the junction box from being damaged when subjected to severe vibration or shaking, but also effectively improve the safety of the junction box, so that the junction box can be used safely and reliably even in harsh working environments. When the box body 1 of the junction box is subjected to the impact of external force and causes severe shaking or is fixedly installed, the shaking of the box body 1 causes the mounting plate 2 66 to shake downward or left and right. At this time, the four support units 68 located on both sides of the mounting plate 2 66 provide reliable support for the left and right shaking of the mounting plate 2 66. The lower end of the top rod 69 is fixedly connected to the spring 2 71. Under the action of the spring 2 71, the lower end of the top rod 69 slides up and down along the top sleeve 70, and the mounting plate 66 is supported by the elastic force of the spring 2 71. The second plate 66 always maintains a horizontal state, thereby ensuring that the box body 1 will not tilt; secondly, the box body 1 presses the mounting plate 66 up and down, so that the pressure rod 653 in the second buffer assembly 65 slides up and down along the side wall of the inner pressure cylinder 652 under the action of the spring four 655, and the pressure rod 653 is elastically connected to the outer pressure cylinder 651 through the spring four 655, so that after the external force is generated or the external force is removed, the spring four 655 can bounce the pressure rod 653 back to the initial position to wait for the next action, and at the same time cooperate with The outer pressure cylinder 651 and the inner pressure cylinder 652 have a buffering effect on the pressure rod 653, thereby ensuring that the pressure rod 653 is buffered when it is pressed violently; at the same time, the first buffer component 64 arranged in the fixed bracket 63 further buffers and relieves the pressure of the second buffer component 65, so as to ensure that the box body 1 fixedly connected by the support mechanism 60 provides effective buffering when it is subjected to severe impact. When the top plate 76 is subjected to downward pressure, it will drive the lower ends of the two hinged connecting rods 75 to move outward, thereby driving the two sliders 72 hinged at the lower ends of the two connecting rods 75 to slide to both sides along the slide groove 2 73, so that the spring three 74 is compressed, and the slider 72 is always maintained in the initial position by relying on the elastic force of the spring three 74, thereby providing upward support for the top plate 76 hinged to the connecting rod 75, so as to reduce the impact caused by the violent shaking of the box body 1, and provide good buffering protection for the junction box. At the same time, it can also better realize the reliable installation and fixation of the dust and high temperature proof box body 1, and further meet the use requirements of the working environment of the junction box.
