Description

Technical Field

[0001] The invention relates to the technical field of distribution boxes, and in particular to a low-voltage integrated distribution box with high safety. Background Art

[0002] Mines need power support when operating, and distribution boxes are needed in the process of using various electrical components. Since the temperature inside the mine is often high, the distribution box is in a high temperature environment. The heat of the internal electrical components cannot be dissipated in time when working, and only circulates in a small space nearby. Its failure rate increases with the increase of temperature, and its service life decreases exponentially with the increase of temperature.

[0003] In the market, cooling is often carried out by blowing the cooling fins with a fan. Although this method can reduce the internal temperature of the distribution box to a certain extent, due to the different powers of the components inside the distribution box, the heat generated is also different. When the temperature in a certain area is too high, the existing fan cooling method cannot cool it down alone, which is easy to affect the overall heat dissipation balance of the distribution box and reduce the heat dissipation effect; and because the internal air of the mine often contains gas and other flammable and explosive gases, when the gas enters the interior of the distribution box, it will corrode the internal electrical components, reduce the service life of the electrical components, and increase the possibility of fire inside the distribution box.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. The present invention sets a heat dissipation and wind control mechanism, and the rotating component works to drive the air inlet pipe to rotate back and forth, so that the output direction of the output end of the air inlet pipe will swing back and forth, so that the air inlet pipe can blow cold air to various angles of multiple groups of heat dissipation fins, thereby enhancing the overall effect of the heat dissipation fins and improving the cooling efficiency; and the extrusion component works to push the two extrusion plates close to each other to form a rapid and short extrusion on the air passing through the air inlet pipe. The extrusion plate extrudes the air, which instantly accelerates the flow rate of the air. At this time, the temperature of the air will be reduced due to the accelerated flow rate, so that the air can take away more heat when it contacts the heat dissipation fins, thereby avoiding the temperature of a certain heat dissipation fin from being too high, thereby forming a heat dissipation effect that is both holistic and targeted for the multiple groups of heat dissipation fins, thereby improving the heat dissipation efficiency.

[0020] 2. The present invention sets a separation and purification mechanism. The driving component drives the first fan to work and draws in external cold air. At the same time, under the centrifugal action of the first fan, the lighter gas is distributed in the middle part of the air inlet tube compared to the air. The driving component drives the second fan to rotate at the same time, so that the gas in the middle of the air inlet tube is sucked into the purification tube by the second fan to be purified, thereby reducing the gas content in the air entering the box, reducing the corrosion of the gas to the electrical components inside the box, and reducing the possibility of fire inside the box.

[0021] 3. The present invention sets an exhaust assembly. When the exhaust assembly works, the exhaust pipe connected to the exhaust cylinder through the bellows moves to the upper end of the heat dissipating fin with high temperature. At the same time, the rotated air inlet pipe delivers air to the inside of the corresponding heat dissipating fin, so that the air can vertically enter the inside of the exhaust pipe and be discharged through the exhaust cylinder. At this time, since the air inlet pipe reduces the temperature of the air, the air with the reduced temperature can vertically cool the heat dissipating fins, avoiding the cold air from dissipating to the inside of other heat dissipating fins, further improving the targeted heat dissipation of the heat dissipating fins, and improving the heat dissipation efficiency.

The second fan 25 is rotatably connected to the purification cylinder 23. The second fan 25 has the same output direction as the first fan 21, both pointing from the outside to the air inlet pipe 4. The purification cylinder 23 extends into the heat dissipation cabinet 14. One end is fixedly connected to the inside with an adsorption plate 24, and the adsorption plate 24 is made of activated carbon material. The driving assembly is electrically connected to the control cabinet 11.

[0040] The driving assembly includes a hollow fixed block 3, which is fixedly connected to the inside of the purification cylinder 23 through a support rod. A micro motor 31 is installed on the top of the fixed block 3. The output end of the micro motor 31 is coaxially fixedly connected to a rotating shaft 32. The rotating shaft 32 is coaxially fixedly connected to a driving gear 33 at one end away from the micro motor 31.

The first driven gear 34 and the second driven gear 35 are rotatably connected to the two side walls inside the fixed block 3 in a one-to-one manner. The end of the first driven gear 34 close to the outside passes through the fixed block 3 and is coaxially fixedly connected to the first fan 21. The end of the second driven gear 35 away from the first fan 21 passes through the fixed block 3 and is coaxially fixedly connected to the second fan 25. The micro motor 31 is electrically connected to the control cabinet 11.

[0041] A plurality of baffle plates 22 are fixedly connected between the outer side of the purification cylinder 23 and the inner wall of the air inlet cylinder 2 .

[0042] Reference Figure 3 , Figure 8-Figure 11 , heat dissipation and wind control mechanism, the heat dissipation and wind control mechanism includes an air inlet pipe 4, the input end of the air inlet pipe 4 is coaxially connected with one end of the purification cylinder 23 extending into the heat dissipation cabinet 14, and the output end is located at the top and points to the heat dissipation fins 13. The bottom of the heat dissipation cabinet 14 is connected with a rotating component and an extrusion component. The output end of the rotating component is connected to the air inlet pipe 4, and is used to drive the air inlet pipe 4 to rotate so that multiple groups of heat dissipation fins 13 are located within the output range after the output end of the air inlet pipe 4 is rotated. The output end of the extrusion component is two extrusion plates 49, and the two extrusion plates 49 are correspondingly located on both sides of the air inlet pipe 4, and the top end initially extends out of the output end of the air inlet pipe 4 and abuts against both sides of the output end of the air inlet pipe 4.

[0043] The rotating assembly includes a first slide rail 44, which is installed at the bottom of the heat dissipation cabinet 14. A first electric slider 43 is slidably installed on the first slide rail 44. A rack 42 is fixedly connected to the first electric slider 43. A gear ring 41 is meshed with the top of the rack 42. The gear ring 41 is coaxially fixedly connected to the outer peripheral side of the bottom of the air inlet pipe 4. The first electric slider 43 is electrically connected to the control cabinet 11.

[0044] Temperature sensors are arranged near the multiple groups of heat dissipation fins 13, and the temperature sensors are electrically connected to the control cabinet 11. When working, the control cabinet 11 receives signals from the temperature sensors. When the signals of multiple temperature sensors exceed a threshold value, that is, when overall heat dissipation is required, the first electric slider 43 is controlled to slide back and forth on the first slide rail 44, so that the output end of the air inlet pipe 4 reciprocates over the multiple groups of heat dissipation fins 13; and when the signal of a single temperature sensor exceeds a threshold value, that is, when separate heat dissipation is required, the first electric slider 43 is controlled to slide to a corresponding position on the first slide rail 44, so that the output end of the air inlet pipe 4 points to the heat dissipation fins 13 with a corresponding high temperature, thereby forming a targeted heat dissipation effect.

[0045] Two support plates 411 are fixedly connected to the bottom of the heat dissipation cabinet 14 , the air inlet pipe 4 is rotatably connected to the two support plates 411 , and the gear ring 41 is located between the two support plates 411 .

[0046] The extrusion assembly includes two second slide rails 5, which are both installed at the bottom of the heat dissipation cabinet 14 and are spaced apart on both sides of the air inlet pipe 4. A second electric slider 51 is slidably installed on the second slide rail 5, and an electromagnetic block 52 is installed on the second electric slider 51. Both sides of the air inlet pipe 4 are connected with a square tube, and a sealing block is sealed and slidably connected in the square tube. The end of the sealing block away from the air inlet pipe 4 is fixedly connected to a push column 48, and the end of the sealing block extending into the air inlet pipe 4 is fixedly connected to the extrusion plate 49. The square tube is away from the air inlet One end of the tube 4 is fixedly connected to a hydraulic cylinder 45, and a hydraulic groove 46 is provided in the hydraulic cylinder 45. A push column 48 seals and penetrates the square cylinder and the hydraulic cylinder 45 at one end away from the sealing block, and is sealed and slidably connected in the hydraulic groove 46. A strong magnetic block 47 is sealed and slidably connected in the hydraulic groove 46. The strong magnetic block 47 and the electromagnetic block 52 on the same side after power is supplied have the same magnetic poles opposite to each other. The hydraulic cylinder 45 between the strong magnetic block 47 and the push column 48 is filled with hydraulic oil, and the second electric slider 51 and the electromagnetic block 52 are both electrically connected to the control cabinet 11.

[0047] The control cabinet 11 controls the second electric slider 51 to work along with the first electric slider 43 , so that the electromagnetic block 52 and the strong magnetic block 47 maintain the same height position, effectively ensuring that the electromagnetic block 52 forms an effective magnetic repulsion effect on the strong magnetic block 47 when working.

[0048] The extrusion plate 49 includes an arc-shaped plate and a straight plate. The outer side of the arc-shaped plate is fixedly connected to one end of the sealing block extending into the air inlet pipe 4. The arc-shaped plate is initially fitted against the inner wall of the air inlet pipe 4. The top of the arc-shaped plate is fixedly connected to the straight plate. The two straight plates are parallel to each other and initially correspond one to one against the two sides of the output end of the air inlet pipe 4. The end of the straight plate away from the arc-shaped plate points to the heat dissipation fins 13.

[0049] Reference Figure 3 and Fig.12, and also includes an exhaust component, which includes a third slide rail 64, the third slide rail 64 is installed on the top of the heat dissipation cabinet 14, and a third electric slider 63 is slidably installed on the third slide rail 64. An exhaust pipe 62 is fixedly connected to the bottom of the third electric slider 63, and a bellows 61 is connected between the exhaust pipe 62 and one end of the exhaust tube 6 extending into the heat dissipation cabinet 14. The exhaust pipe 62 is spaced away from one end of the bellows 61 and is located above the multiple groups of heat dissipation fins 13. The multiple groups of heat dissipation fins 13 are located on the sliding track of the third electric slider 63, and the third electric slider 63 is electrically connected to the control cabinet 11.

[0050] During operation, when the signal received by the control cabinet 11 from a single temperature sensor exceeds a threshold value, that is, when separate heat dissipation is required, the control cabinet 11 controls the third electric slider 63 to slide to a corresponding position to form a targeted heat dissipation effect.

[0051] In the present invention, when the mine power distribution box is in use, the electrical components 12 inside the box body 1 will generate heat, and the heat generated by the electrical components 12 will be discharged into the heat dissipation cabinet 14 through the heat transfer end of the heat dissipation fins 13;

[0052] When heat dissipation is performed, the control cabinet 11 starts the micro motor 31. The output end of the micro motor 31 drives the rotating shaft 32 to rotate. The rotation of the rotating shaft 32 drives the driving gear 33 to rotate coaxially. When the driving gear 33 rotates, it meshes with the first driven gear 34, so that the first driven gear 34 rotates, thereby driving the first fan 21 to rotate.

[0053] The rotation of the first fan 21 will draw the outside air into the air inlet 2 through the air inlet 2, until the air reaches the baffle plate 22 fixedly connected inside the air inlet 2. Since there are multiple baffle plates 22, the air will have its flow rate reduced when it reaches the baffle plates 22. At this time, the operation of the first fan 21 will form a centrifugal effect on the nearby air.

[0054] When the driving gear 33 rotates, it will mesh with the second driven gear 35 at the same time, so that the second driven gear 35 rotates, thereby driving the second fan 25 to rotate. At this time, the second fan 25 will produce a suction effect on the air at the baffle plate 22 and the front end. Since the air in the mine often carries gas, if the gas enters the inside of the distribution box, it will corrode its internal components, thereby increasing the probability of fire inside the distribution box. The mass of gas is lighter than that of air, and the centrifugal force of the first fan 21 is smaller. Therefore, when the first fan 21 rotates, the position of the gas relative to the air will remain in the middle part of the air inlet cylinder 2. At this time, the rotation of the second fan 25 will produce suction on the gas, so that the gas in the middle of the air inlet cylinder 2 is sucked into the purification cylinder 23 by the second fan 25;

[0055] The air carrying gas entering the purification cylinder 23 is then absorbed by the adsorption plate 24 inside the purification cylinder 23, while the relatively heavy air enters the air inlet pipe 4 through the gap between the baffle plates 22, thereby reducing the gas content in the air entering the box 1, reducing the corrosion of the gas to the electrical components 12 inside the box 1, and reducing the possibility of fire inside the box 1;

[0056] When the air enters the air inlet pipe 4, it will be blown to the heat dissipation fins 13 through the output end at the top of the air inlet pipe 4 to cool it down.

[0057] At this time, the first electric slider 43 is started, so that the first electric slider 43 slides along the inner wall of the first slide rail 44. The sliding of the first slide rail 44 will drive the rack 42 to move synchronously. The movement of the rack 42 will mesh with the gear ring 41, so that the gear ring 41 drives the air inlet pipe 4 to rotate along the inner wall of the support plate 411. At this time, the output direction of the output end of the air inlet pipe 4 will swing back and forth, so that the air inlet pipe 4 can blow cold air to various angles of the multiple groups of heat dissipation fins 13, thereby improving the cooling efficiency of the heat dissipation fins 13;

[0058] At the same time, when the temperature of a certain heat dissipation fin 13 is relatively high, taking the heat dissipation fin 13 on the right as an example, the second electric slider 51 on the opposite side is started, so that the second electric slider 51 moves upward along the inner wall of the second slide rail 5, and the upward movement of the second electric slider 51 will drive the electromagnetic block 52 to move synchronously. At this time, when the output end of the air inlet pipe 4 rotates to the right, the electromagnetic block 52 on the left is started, so that the electromagnetic block 52 works to generate a magnetic field. At this time, the electromagnetic block 52 and the strong magnetic block 47 have the same magnetic poles opposite to each other. At this time, the electromagnetic block 52 will produce a magnetic repulsion effect on the strong magnetic block 47, so that the strong magnetic block 47 slides from the outside to the inside along the inner wall of the hydraulic groove 46 opened inside the hydraulic cylinder 45. The sliding of the strong magnetic block 47 will squeeze the hydraulic oil inside the hydraulic groove 46. At this time, the hydraulic oil will generate a thrust on the push column 48, so that the push column 48 pushes the extrusion plate 49 from the outside to the inside through the sealing block;

[0059] At this time, when the air in the air inlet pipe 4 is discharged through the output end, it will be quickly and briefly squeezed by the squeezing plate 49. The squeezing of the air by the squeezing plate 49 will instantly increase the flow rate of the air. At this time, the temperature of the air will be reduced due to the increased flow rate, so that the air can take away more heat when it contacts the heat dissipation fins 13, thereby preventing the temperature of a certain heat dissipation fin 13 from being too high.

[0060] At the same time, when the temperature of a certain heat dissipation fin 13 is too high, the third electric slider 63 is started, so that the third electric slider 63 slides along the inner wall of the third slide rail 64. The sliding of the third electric slider 63 will drive the exhaust pipe 62 to move synchronously, so that the exhaust pipe 62 moves to the upper end of the heat dissipation fin 13 with high temperature. At this time, when the air inlet pipe 4 sends air into the interior of the heat dissipation fin 13, the air can vertically enter the interior of the exhaust pipe 62 and be discharged through the exhaust pipe 6. At this time, because the air inlet pipe 4 reduces the temperature of the air, the air with the reduced temperature can vertically cool the heat dissipation fin 13, avoiding the cold air from escaping to the interior of other heat dissipation fins 13, thereby reducing the heat dissipation efficiency inside the distribution box;

[0061] This achieves the effect of heat dissipation and avoids the situation where the temperature inside the box body 1 is too high, causing the electrical components 12 to catch fire and explode.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
