DETAILED DESCRIPTION

[0032] like Figure 1-Figure 10 As shown, a box-type substation includes a box body 1, both sides of which are provided with through grooves 101, and a filter is fixedly installed in the through grooves 101. Through this structure, the heat dissipation of the box body 1 can be achieved, and at the same time, external dust can be prevented from entering the box body 1. A plurality of inclined rain shields are fixedly arranged on the outer side of the box body 1 at the position of the through grooves 101, which can prevent rainwater from entering the box body 1 through the through grooves 101.

[0033] The box body 1 is provided with a partition plate 7 fixedly disposed on one side of the through slot 101, and a slide plate 6 is disposed on the side of the partition plate 7 close to the through slot 101. Figure 4 As shown, the slide plate 6 is slidably arranged between the inner wall of the box body 1 and the partition plate 7, and the slide plate 6 is sealed with the inner wall of the box body 1 and the partition plate 7 (specifically, a sealing strip can be bonded on the outer side of the slide plate 6 to improve the sealing performance). A through notch is opened on the partition plate 7, and a fixing plate 8 is fixedly arranged in the notch and the through groove 101. Figure 2-Figure 4 As shown, the fixed plate 8 is evenly provided with a plurality of strip-shaped guide grooves 801, and the plurality of guide grooves 801 are distributed in a linear array in the vertical direction. The second baffle 15 is slidably provided on the side of the partition 7 close to the through groove 101, and the first baffle 9 is slidably provided on the inner wall of the box body 1 at the through groove 101. The first baffle 9 and the second baffle 15 are both in a state of being fitted with the fixed plate 8. Figure 6 As shown, the first baffle plate 9 is provided with a plurality of first strip grooves 902, and the second baffle plate 15 is provided with a plurality of second strip grooves 1502. In actual use, the through groove 101 and the notch can be sealed by moving the first baffle plate 9 and the second baffle plate 15 in the vertical direction.

[0034] A rotating shaft 2 is provided on one side of the partition 7 close to the through groove 101, and the rotating shaft 2 is rotatably matched with the box body 1, and the rotating shaft 2 is matched with the slide plate 6 through a limiting assembly. When the slide plate 6 moves in the vertical direction, the slide plate 6 can drive the rotating shaft 2 to rotate through the limiting assembly, and an annular plate 14 is fixedly sleeved at the outer side of the rotating shaft 2 near the bottom end. When the annular plate 14 rotates, the annular plate 14 can drive the first baffle plate 9 and the second baffle plate 15 to move in the vertical direction through the extrusion assembly, thereby realizing alternating closure of the through groove 101 and the notch. In this process, the gas in the external environment can be drawn into between the partition 7 and the inner wall of the box body 1 and finally squeezed into the box body 1, which is beneficial to accelerate the heat dissipation of the box body 1.

[0035] Combination Figure 2-Figure 11 As shown, the extrusion assembly includes two pressure rods 13 disposed on the top surface of the annular plate 14, the pressure rods 13 are fixedly connected to the annular plate 14, and the two pressure rods 13 are symmetrical about the axis of the annular plate 14;

[0036] Further, a first boss 901 is fixedly provided on the inner side of the first baffle 9 and near the bottom end, and a second boss 1501 is fixedly provided on the inner side of the second baffle 15 and near the bottom end. Figure 5As shown, the bottom of the first boss 901 and the second boss 1501 are elastically mounted with a slider 21, and the bottom surface of the slider 21 is fixedly provided with a short pressing block 11 and a long pressing block 12, and the short pressing block 11 and the long pressing block 12 are arranged along the length direction of the slider 21. Figure 7 As shown, the short pressing block 11 and the long pressing block 12 are both arranged in a stepped shape. The side of the short pressing block 11 close to the pressing rod 13 is provided with a second inclined surface 1101, and the side of the long pressing block 12 close to the pressing rod 13 is provided with a first inclined surface 1201. Specifically, the vertical height of the first inclined surface 1201 is twice the vertical height of the second inclined surface 1101. In addition, the side of the short pressing block 11 and the long pressing block 12 close to the pressing rod 13 is also provided with a third inclined surface 10, and the third inclined surface 10 is located below the first inclined surface 1201 and the second inclined surface 1101. Figure 7 As shown, the long pressing block 12 under the first boss 901 is located close to the rotating shaft 2 , while the short pressing block 11 under the second boss 1501 is located close to the rotating shaft 2 .

[0037] Furthermore, a floating plate 16 is sleeved on the outer side of the rotating shaft 2, and the floating plate 16 can move in the vertical direction relative to the rotating shaft 2, and a pull rope 19 is fixedly arranged between the bottom surface of the floating plate 16 and the end surface of the slider 21 close to the rotating shaft 2, and through holes for the pull rope 19 to pass through can be opened on the first boss 901 and the second boss 1501, so that the pull rope 19 can slide relative to the first boss 901 and the second boss 1501.

[0038] The above-mentioned limit assembly includes a protrusion 601 fixedly connected to the slide plate 6, referring to Fig.11 As shown, the slide plate 6 is provided with a through circular hole, and the rotating shaft 2 passes through the circular hole. The protrusion 601 is fixedly arranged on the inner wall of the circular hole. Figure 8-Figure 9 As shown, an inclined first arc groove 205 is provided on the outer peripheral wall of the rotating shaft 2. When the protrusion 601 slides along the first arc groove 205, the rotating shaft 2 can rotate to a certain angle. The top of the first arc groove 205 is connected to the upper groove 201, and the top of the upper groove 201 is connected to the inclined second arc groove 202. A descending groove 203 is provided on one side of the upper groove 201. Specifically, the top of the descending groove 203 is connected to the second arc groove 202, and the bottom of the descending groove 203 is connected to the third arc groove 204. The end of the third arc groove 204 away from the descending groove 203 is connected to the first arc groove 205. Figure 8As shown, the first arc groove 205, the upper groove 201, the second arc groove 202, the lower groove 203 and the third arc groove 204 are connected end to end, so that the protrusion 601 can slide in a cycle along the first arc groove 205, the upper groove 201, the second arc groove 202, the lower groove 203 and the third arc groove 204, and the above-mentioned first arc groove 205, the upper groove 201, the second arc groove 202, the lower groove 203 and the third arc groove 204 are all opened on the outer wall of the rotating shaft 2.

[0039] In the initial state, the pressure rod 13 and the long pressure block 12 and the short pressure block 11 are all in a staggered state, so that the first baffle plate 9 and the second baffle plate 15 are both at the bottom end. At this time, the guide groove 801 on the fixing plate 8 on one side of the first baffle plate 9 is aligned with the first strip groove 902 on the first baffle plate 9, and the guide groove 801 on the fixing plate 8 on one side of the second baffle plate 15 is aligned with the second strip groove 1502 on the second baffle plate 15, so that the airflow on both sides of the box body 1 can flow naturally, thereby realizing natural heat dissipation of the box body 1;

[0040] When the power consumption of the electrical components in the box body 1 increases and the temperature inside the box body 1 rises significantly, the slide plate 6 can be driven to reciprocate in the vertical direction. Specifically, when the slide plate 6 moves upward, the protrusion 601 on the slide plate 6 will move upward along the first arc groove 205 and drive the shaft 2 to rotate a certain angle, so that the shaft 2 can drive the annular plate 14 to rotate. At this time, a pressure rod 13 on the annular plate 14 contacts the long pressure block 12 under the first boss 901, and the other pressure rod 13 on the annular plate 14 contacts the short pressure block 11 under the second boss 1501. Since the vertical height of the first inclined surface 1201 on the long pressure block 12 is twice the vertical height of the second inclined surface 1101 on the short pressure block 11, the two pressure rods 13 are respectively During the squeezing process with the first inclined surface 1201 and the second inclined surface 1101, the distance that the first boss 901 and the first baffle plate 9 move upward is twice the distance that the second boss 1501 and the second baffle plate 15 move upward. In this case, the first strip groove 902 and the guide groove 801 on the fixing plate 8 on one side of the first baffle plate 9 are still aligned, while the second strip groove 1502 and the guide groove 801 on the fixing plate 8 on one side of the second baffle plate 15 are staggered, so that the through groove 101 on the side of the box body 1 is in an open state, and the notch on the partition plate 7 is closed. When the protrusion 601 enters the upper groove 201 from the first arc groove 205 and moves upward along the upper groove 201, a negative pressure will be formed under the slide plate 6. The state enables the gas outside the box body 1 to be drawn into between the partition plate 7 and the inner wall of the box body 1. When the protrusion 601 enters the second arc groove 202 from the upper groove 201 and slides along the second arc groove 202, the cooperation between the protrusion 601 and the second arc groove 202 can drive the shaft 2 to rotate again, so that the shaft 2 can drive the annular plate 14 and the pressure rod 13 on the top surface thereof to rotate again. At this time, the pressure rod 13 will contact and squeeze the third inclined surface 10 on the long pressure block 12 and the short pressure block 11. Since the vertical height of the third inclined surface 10 on the short pressure block 11 is equal to the vertical height of the third inclined surface 10 on the long pressure block 12, the distance that the first baffle plate 9 and the second baffle plate 15 are driven to move upward by the cooperation between the pressure rod 13 and the third inclined surface 10 is At this time, the first strip groove 902 and the guide groove 801 on the fixing plate 8 on one side of the first baffle plate 9 are in a staggered state, while the second strip groove 1502 and the guide groove 801 on the fixing plate 8 on one side of the second baffle plate 15 are in an aligned state. In this case, the through groove 101 is in a closed state, and the notch on the partition plate 7 is in an open state. When the slide plate 6 moves downward, the protrusion 601 can move downward along the descending groove 203. At this time, the downwardly moving slide plate 6 can squeeze the gas drawn into between the partition plate 7 and the inner wall of the box body 1 into the box body 1 through the notch, thereby accelerating the heat dissipation of the box body 1. When the protrusion 601 slides from the descending groove 203 to the third arc groove 204 and slides along the third arc groove 204,The cooperation between the protrusion 601 and the third arc groove 204 can drive the rotating shaft 2 to rotate in the opposite direction, and the annular plate 14 and the pressure rod 13 will also rotate in the opposite direction to reset and stagger with the long pressure block 12 and the short pressure block 11. Repeat the above operation. During the reciprocating movement of the slide plate 6 up and down, the gas outside the box body 1 will be continuously drawn into the box body 1, thereby accelerating the heat dissipation of the box body 1. When the protrusion 601 enters the first arc groove 205 from the third annular groove, the rotating shaft 2 completes a cycle of operation.

[0041] When water enters the box body 1 due to heavy rain, the floating plate 16 in the box body 1 will move upward due to the buoyancy. Figure 4-Figure 5 As shown, during the upward movement of the floating plate 16, the floating plate 16 can pull the slider 21 through the pull rope 19, so that the slider 21 moves toward the direction close to the rotating shaft 2. During this process, the short pressure block 11 under the first boss 901 will move to the side of one of the pressure rods 13, and the long pressure block 12 under the second boss 1501 will move to the side of the other pressure rod 13. Therefore, during the upward movement of the slide plate 6 to drive the rotating shaft 2 and the annular plate 14 to rotate, the distance that the second baffle plate 15 moves upward through the pressure rod 13 is twice the distance that the first baffle plate 9 moves upward. In this case, the first strip groove 902 and the guide groove 801 on the fixed plate 8 on one side of the first baffle plate 9 are in a staggered state, while the second strip groove 1502 and the guide groove 801 on the fixed plate 8 on one side of the second baffle plate 15 are in an aligned state, so that the through groove 101 on the box body 1 is blocked, and The notch on the partition 7 is in an open state, so during the upward movement of the slide plate 6, the accumulated water in the box body 1 will be drawn into the space between the partition plate 7 and the inner wall of the box body 1. When the protrusion 601 moves upward along the second arc groove 202, according to the above description, the first baffle plate 9 and the second baffle plate 15 move upward by an equal distance, so that the notch can be sealed by the second baffle plate 15, and the through groove 101 on the box body 1 is in an open state. At this time, during the downward movement of the slide plate 6, the water drawn into the space between the partition plate 7 and the inner wall of the box body 1 can be squeezed out through the through groove 101. Similarly, when the protrusion 601 enters the first arc groove 205 from the third arc groove 204, the rotating shaft 2 completes a cycle of operation, and the above steps are repeated. The accumulated water in the box body 1 can be continuously squeezed out through the through groove 101, thereby preventing the water level in the box body 1 from continuing to rise.

[0042] To summarize, this device can achieve alternating blocking of the notch and the through groove 101 by means of the first baffle 9 and the second baffle 15. During the heat dissipation process, the second baffle 15 can block the notch on the partition 7, so that the gas in the external environment is continuously squeezed into the box body 1, thereby accelerating the heat dissipation of the box body 1. When there is a lot of water accumulated in the box body 1, the through groove 101 can be blocked by the first baffle 9, so that the accumulated water in the box body 1 can be continuously squeezed out through the through groove 101 by the up and down movement of the slide plate 6, thereby preventing the accumulated water in the box body 1 from continuing to rise.

[0043] like Figure 1-Figure 3 As shown, an exhaust groove can be opened on the top surface of the box body 1, and an inverted V-shaped top plate is fixedly provided on the top of the box body 1. Through the exhaust groove, when the slide plate 6 moves downward to squeeze the external gas into the inside of the box body 1, the gas inside the box body 1 can be discharged through the exhaust groove.

[0044] like Figure 2 As shown, in order to drive the slide plate 6 to move upward, a turntable 4 is provided on one side of the partition plate 7 close to the through slot 101, and a support rod 5 is provided between the turntable 4 and the slide plate 6. Specifically, a pin is rotatably installed on the end surface of the turntable 4 close to the partition plate 7. The pin is located at the outer edge of the turntable 4, and the pin passes through the support rod 5 and rotates with the support rod 5. The bottom end of the support rod 5 is hinged to the slide plate 6. A connecting shaft 3 is fixedly provided on the turntable 4. In actual use, a motor can be installed on the inside or outside of the box body 1, and the output shaft of the motor is connected to the connecting shaft 3 in a transmission manner, so as to drive the slide plate 6 to reciprocate in the vertical direction. Of course, this is only one of the implementation methods for driving the slide plate 6 to move. In actual operation, it can also be done through structures such as electric push rods.

[0045] In actual use, a temperature sensor and a liquid level gauge can be installed in the box 1, and the temperature sensor and the liquid level gauge are electrically connected to the above-mentioned motor. Through this structure, the motor can be started when the temperature in the box 1 rises or there is a lot of water accumulation. Of course, the motor can also be manually controlled by the staff.

[0046] A support plate is rotatably mounted on the top end of the rotating shaft 2 , and the support plate is fixedly connected to the box body 1 .

[0047] Reference Figure 3 As shown, a guide bar 17 is fixedly provided on one side of the inner wall of the box body 1 opposite to the partition 7 and on the partition 7. The cross section of the guide bar 17 is set to be L-shaped, and the first baffle 9 and the second baffle 15 slide between the two guide bars 17 respectively.

[0048] The bottom surfaces of the first boss 901 and the second boss 1501 are both provided with sliding grooves, and the slider 21 is slidably set in the sliding grooves. A transverse axis 20 is fixedly set at the inner end surface of the sliding groove. The transverse axis 20 passes through the slider 21 and slides with it. A retaining ring is fixedly set at one end of the transverse axis 20 passing through the slider 21 to prevent the slider 21 from detaching from the transverse axis 20. A spring is fixedly set between the inner end surface of the sliding groove and the slider 21.

[0049] Combination Figure 2 , Figure 6 As shown, a telescopic rod 18 is arranged below the floating plate 16 , and the telescopic rod 18 includes a sliding rod and a rod sleeve slidably sleeved on the outside of the sliding rod. The top end of the sliding rod is fixedly connected to the floating plate 16 , and the bottom end of the rod sleeve is fixedly connected to the box body 1 .

[0050] Reference Figure 9-10 As shown, a guide plate 22 is hinged at the junction of the second arc groove 202 and the downward groove 203. The guide plate 22 is tilted and elastically matched with the rotating shaft 2. In the initial state, the guide plate 22 can only rotate clockwise relative to the rotating shaft 2. When the protrusion 601 moves upward along the second arc groove 202, it can squeeze the guide plate 22 to deflect it. When the protrusion 601 moves downward, the guide plate 22 can prevent the protrusion 601 from returning to the second arc groove 202. Similarly, a limit plate 23 is hinged at the junction of the third arc groove 204 and the first arc groove 205. The limit plate 23 is elastically matched with the rotating shaft 2. In the initial state, the limit plate 23 can only rotate clockwise relative to the rotating shaft 2. When the protrusion 601 enters the first arc groove 205 from the third arc groove 204, it can drive the limit plate 23 to deflect. When the protrusion 601 passes over the limit plate 23, the limit plate 23 is set to ensure that the protrusion 601 enters the first arc groove 205. A first spring is fixedly arranged between the side of the guide plate 22 close to the upper groove 201 and the rotating shaft 2, and between the side of the limit plate 23 close to the third arc groove 204 and the rotating shaft 2.
