[0002] The box-type substation, also called prepackaged substation or prepackaged substation, is a kind of high-voltage switchgear, distribution transformer and low-voltage distribution device arranged in an integrated factory according to a certain wiring scheme. It is a compact indoor and outdoor distribution device. When water enters the 10kV box-type substation and the electrical components inside the 10kV box-type substation short circuit, the internal master control switch will trip and power off, thereby realizing self-protection of the 10kV box-type substation.

[0023] 2. The application designs a dust cleaning mechanism, namely a cleaning brush and a driving assembly. When the temperature inside the box suddenly rises, on the one hand, the heat generated by the power distribution facilities continues to work, and on the other hand, a large amount of dust adheres to the filter screen, resulting in poor heat dissipation effect, and the heat continues to accumulate in the box and cannot be discharged in time. When this happens, the controller starts the driving motor, the rotating disc is fixedly connected to the output end, thereby driving the rotating disc to rotate, the cleaning brush is slidingly connected to the two guide rails, the rotating disc and the cleaning brush are hingedly connected to the two ends of the connecting rod, thereby driving the cleaning brush to slide downward, and as the rotating disc continues to rotate, the cleaning brush automatically rises when sliding to the lowest position.

DETAILED DESCRIPTION

[0043] The technical solutions of the present application will be further described below in combination with the drawings and through specific embodiments.

[0044] The drawings are only used for illustrative purposes, and the representation is only a schematic diagram, not a physical diagram, and should not be understood as a limitation on the patent; in order to better illustrate the embodiments of the present application, some components of the drawings may be omitted, enlarged or reduced, and do not represent the actual product size.

[0045] Embodiment one

[0046] The present application provides a technical solution, referring to Figure 1 and Figure 2 As shown in the figure, a multifunctional box-type substation comprises a box 1, a power distribution facility 2, a controller, a temperature monitoring mechanism 3, a dust cleaning mechanism 4, and a water immersion treatment mechanism 5. The power distribution facility 2 is arranged inside the box 1. An air inlet 10 and an air outlet 11 are arranged at the top of one side and the bottom of the other side of the box 1, respectively. The air inlet 10 and the air outlet 11 are usually arranged on the outside of the box-type substation. The cold air is drawn in through the air inlet 10, and the hot air is discharged through the air outlet 11. Since the density of the cold air is greater than that of the hot air, the air inlet 10 is arranged at the upper end of one side of the box-type substation, and the air outlet 11 is arranged at the lower end of the other side. In this way, the cold air drawn in can automatically sink from the upper part to the lower part inside the box-type substation, and the heat generated by the operation of the power distribution facility 2 in the substation can automatically sink. Arranging the air outlet 11 at the lower end can accelerate the efficiency of hot air discharge.

[0047] The water immersion treatment mechanism 5 is arranged on the exhaust port 11 to prevent water from entering, and comprises a baffle 50 and an extension assembly 51. The exhaust port 11 is arranged at one end of the inside of the box body 1 and is provided with two insertion slots 110, and the bottom of the two insertion slots 110 is fixedly provided with a limiting plate 111. The extension assembly 51 is fixedly arranged on the inner wall of the box body 1, and the baffle 50 is fixedly arranged on the extension assembly 51. The width of the baffle 50 is consistent with the spacing of the two insertion slots 110.

[0048] The dust cleaning mechanism 4 is arranged on the outer wall of the air inlet 10 to clean dust at the air inlet 10. The dust cleaning mechanism 4 comprises a cleaning brush 40 and a driving assembly 41. The air inlet 10 is fixedly arranged at one end of the inside of the box body 1 and is provided with two guide rails. The cleaning brush 40 is slidingly arranged between the two guide rails. The driving assembly 41 is arranged on the inner wall of the box body 1 and is hingedly connected with the cleaning brush 40.

[0049] The temperature monitoring mechanism 3 is arranged above the water immersion treatment mechanism 5 to monitor the temperature inside the box body 1. The temperature monitoring mechanism 3 comprises a temperature sensor 30 and a heat dissipation assembly 31. The end of the two insertion slots 110 away from the inner wall of the box body 1 is fixedly provided with a cover 112. The heat dissipation assembly 31 is arranged in the cover 112. The inner ring of the cover 112 is consistent with the size of the exhaust port 11. The temperature sensor 30, the extension assembly 51, the driving assembly 41 and the heat dissipation assembly 31 are electrically connected with the controller.

[0050] Referring to Figure 6 The driving assembly 41 comprises a driving motor 410, a rotating disc 411 and a connecting rod 412. The driving motor 410 is inserted into the outer wall of the box body 1 and its output end extends into the inside of the box body 1.

A protective shell is fixedly arranged on the side wall of the box body 1. The driving motor 410 is arranged in the protective shell. The driving motor 410 is electrically connected with the controller. When the temperature inside the box body 1 suddenly rises, on one hand, it is because of the heat generated by the power distribution facility 2 continuously working. On the other hand, it is because a large amount of dust adheres to the filter screen 100, which leads to poor heat dissipation effect and continuous accumulation of heat in the box body 1. When this situation occurs, the controller starts the driving motor 410. Since the rotating disc 411 is fixedly connected with the output end of the driving motor 410, the rotating disc 411 rotates. Since the cleaning brush 40 is slidingly connected with the two guide rails, the rotating disc 411 and the cleaning brush 40 are hingedly connected with the two ends of the connecting rod 412, and the cleaning brush 40 slides downward. With the continuous rotation of the rotating disc 411, the cleaning brush 40 automatically rises when it slides to the lowest position. Through the continuous vertical reciprocating sliding of the cleaning brush 40, the dust adhering to the filter screen 100 is cleaned, which plays a dust cleaning role.

When the precipitation is small, the rainproof plate 114 plays a role of rain blocking. Since the position of the exhaust port 11 is relatively low, the plurality of blocking rods 115 play a role of shielding to prevent some animals from entering the box 1.

[0055] With reference to Figure 8 As shown, the two ends of the exhaust port 11 are provided with grooves, and the top of the limiting plate 111 and the inside of each groove are provided with sealing strips 116.

When the first rack 61 descends in the interior of the first slide rail, the first gear 64 and the first rack 61 are in meshing connection, the first gear 64 and the driving wheel 65 are fixedly connected with the first hinge shaft, the second gear 66 and the driven wheel 67 are fixedly connected with the second hinge shaft, the driving wheel 65 and the driven wheel 67 are sleeved through the belt 68, and then the second gear 66 is driven to rotate clockwise. As shown, the inner wall of the box body 1 is fixedly provided with two support rods, the first and second hinge shafts are inserted between the two support rods, the first gear 64 and the driving wheel 65 are fixedly arranged on the first hinge shaft respectively, the second gear 66 and the driven wheel 67 are fixedly arranged on the second hinge shaft respectively, the belt 68 is sleeved between the driving wheel 65 and the driven wheel 67, and the driving wheel 65 is smaller than the driven wheel 67. The first rack 61 is in meshing connection with the first gear 64. When the first rack 61 descends in the interior of the first slide rail, the first gear 64 and the first rack 61 are in meshing connection, the first gear 64 and the driving wheel 65 are fixedly connected with the first hinge shaft, the second gear 66 and the driven wheel 67 are fixedly connected with the second hinge shaft, the driving wheel 65 and the driven wheel 67 are sleeved through the belt 68, and then the second gear 66 is driven to rotate clockwise.

[0060] The working principle of the present application: the internal temperature of the box 1 suddenly becomes high, on the one hand because of the heat generated by the power distribution facilities 2 working continuously, and on the other hand because a large amount of dust adheres to the filter screen 100, resulting in poor heat dissipation effect, and the heat continuously accumulates in the box 1 and cannot be discharged in time, when this situation occurs, the controller starts the driving motor 410, since the rotating disc 411 is fixedly connected with the output end thereof, thereby driving the rotating disc 411 to rotate, and since the cleaning brush 40 is slidingly connected with the two guide rails, the rotating disc 411 and the cleaning brush 40 are respectively hinged with the two ends of the connecting rod 412, thereby driving the cleaning brush 40 to slide downward, with the continuous rotation of the rotating disc 411, the cleaning brush 40 automatically rises when sliding to the lowest position, and the dust adhering to the filter screen 100 is cleaned through the continuous vertical reciprocating sliding of the cleaning brush 40, thereby playing a dust cleaning effect.

[0061] Since the cleaning brush 40 is attached to the outer wall of the filter screen 100, and the collecting box 113 is located below the cleaning brush 40, the dust cleaned from the filter screen 100 falls directly into the inside of the collecting box 113, and when the collecting box 113 is full, it is emptied by manual removal.

[0062] The controller has a preset standard value of the operating temperature of the box 1 inside, the temperature sensor 30 monitors the internal temperature of the box 1 in real time, when the internal temperature exceeds the standard value, the signal is sent to the controller, thereby starting the two micro-motors 311 through the controller, since each fan 312 is fixedly connected with the output end of a micro-motor 311, thereby driving the two fans 312 to rotate, under the cooperation of the air inlet 10 and the air outlet 11, the cooler air enters the inside of the box 1 from the air inlet 10, and the hot air in the inside of the box 1 is extracted from the air outlet 11 by the two fans 312, thereby achieving cooling and preventing the power distribution facilities 2 from being burned out due to the high internal temperature of the box 1.

[0063] When the precipitation is small, the rain shield 114 plays a rain blocking effect, since the position of the air outlet 11 is low, the several blocking rods 115 play a shielding effect, thereby preventing some animals from entering the box 1.

[0064] When the precipitation is large, the rain shield 114 plays a reduced effect, at this time, in order to prevent rainwater from entering the air outlet 11 and damaging the micro-motor 311, the controller starts the electric push rod 510, thereby making the output end thereof extend downward, since the horizontal rod 512 is fixedly connected with the top of the baffle 50, and since the width of the baffle 50 is consistent with the spacing of the two insertion grooves 110, thereby driving the baffle 50 to be inserted into the inside of the two insertion grooves 110, thereby plugging the air outlet 11, thereby preventing rainwater from entering.

[0065] When the precipitation is large, water is easy to accumulate on the road surface and is deep. Since the exhaust port 11 is designed to be low, when the baffle 50 blocks the exhaust port 11, the water pressure is large, which can press the baffle 50 open, so that a gap appears between the baffle 50 and the inner wall of the box 1. When the baffle 50 blocks the exhaust port 11, the pull block 6 is lowered together with the baffle 50. Since the pull block 6 is fixedly connected with the first rack 61 through the first inserting rod 60, and the first rack 61 is slidingly connected with the first slide rail, the first rack 61 is driven to descend in the first slide rail. In the initial state, the return spring 63 is in a contracted state. When the baffle 50 is lowered, the return spring 63 changes from the contracted state to the extended state.

[0066] When the first rack 61 descends in the first slide rail, since the first gear 64 and the first rack 61 are in meshing connection, the first gear 64 and the driving wheel 65 are fixedly connected with the first hinge shaft, the second gear 66 and the driven wheel 67 are fixedly connected with the second hinge shaft, and the driving wheel 65 and the driven wheel 67 are sleeved with the belt 68, so as to drive the second gear 66 to rotate clockwise.

[0067] When the second gear 66 rotates clockwise, since the second gear 66 is in meshing connection with the second rack 69, and the second rack 69 is slidingly connected with the second slide rail, the second rack 69 is driven to ascend in the second slide rail. Since the slide column 690 is slidingly connected with the third slide rail, the top rod 691 is fixedly designed on the outer wall of the second rack 69 and the slide column 690. The two ends of the swing rod 692 are provided with contact grooves for sleeving the two top rods 691. The top rod 691 on the second rack 69 upwardly abuts against the contact groove at one end of the swing rod 692, so that the contact groove at the other end of the swing rod 692 presses the top rod 691 on the slide column 690. Since the bottom of the slide column 690 is fixedly connected with the second inserting rod 693, the bottom of the second inserting rod 693 is hingedly connected with the sleeve block 694, the control handle 696 is sleeved with the sleeve block 694, and the total switch 695 is closed by downwardly pressing the control handle 696 through the sleeve block 694, so as to prevent the water in the box 1 from contacting the electric wire to cause short circuit, thereby protecting the power distribution facility 2.
