[0009] The front and back sides of the displacement bar are connected to the square channel in a rotatable manner.

[0020] The beneficial effects of the present invention are:

[0021] The present invention gathers the precipitation through the liquid storage shell and discharges the precipitation through the side discharge hole, so as to judge the strength of the precipitation. When the precipitation is not strong, the foam platform in the liquid storage shell cannot move toward the head, thus ensuring the normal shape of the through window;

[0022] During heavy rainfall, the amount of liquid in the liquid storage shell gradually increases. When the foam platform is slowly displaced toward the head, the driving platform at the tail of the foam platform drives one end of the displacement bar to swing and deviate, so that the other end of the displacement bar is separated from the circular groove, and the top contact pressure between the displacement bar and the circular groove is released. At this time, the embedded rod moves toward the tail to pull the spiral beryllium copper wire to lengthen. When the embedded rod moves toward the tail, one end of the top rod is driven to swing and compress the pressure plate to displace the traction cover plate, thereby weakening the opening range of the through window, so as to prevent precipitation from flowing into the shell through the through window during heavy rainfall, causing the structures inside the shell to be eroded by precipitation.

[0023] During the swing of the top connecting rod, the disc 3 on the top connecting rod is pulled to rotate on the inner wall of the ring body, thereby pulling the disc 2 and the V-shaped bar barrel connected to one end of the disc 2 to rotate, so that the fan swings and blows air toward the air inlet hole above the fan, and the normal temperature control and heat removal of the structure inside the shell is ensured through the air inlet hole;

[0024] After the precipitation is over, the water level in the liquid storage shell slowly drops, and the foam platform inside the liquid storage shell moves to the tail of the inner wall of the liquid storage shell and compresses the compression rod, so that the compression rod moves toward the tail to compress one end of the through hole and separates from the inside of the buckle strip, releasing the end constrained by the buckle strip; in this way, the embedded rod moves toward the head due to the elastic recovery property of the spiral beryllium copper wire, and the top connecting rod returns to its original position due to the elastic recovery property of the elastic rod, and the traction cover swings to open the through window, and the traction coupling seat swings back to its original position, so that the fan delivers gas to the outside of the opened through window, so that the purpose of returning the top connecting rod to its original position is achieved, ensuring that the shell seals and covers the through window during severe precipitation, and also ensuring the normal heat removal and temperature control inside the shell.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described in conjunction with the drawings of specific embodiments of the present invention. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Reference Figure 1-Figure 8The embodiment of the present invention provides an offshore wind power environmentally friendly gas-insulated metal-enclosed switchgear, comprising a shell 12, in which a switchgear 11 is installed, the size of the switchgear 11 is adapted to the space inside the shell 12, an air inlet hole 13 is reserved at the head of the shell 12, a baffle 17 is installed at the head of the shell 12, the baffle 17 is bent at a right angle, the vertical section of the baffle 17 is fixedly connected to the shell 12, the horizontal section of the baffle 17 is installed above the air inlet hole 13, a clean part is installed in the air inlet hole 13, and the clean part It is used to intercept floating objects in the gas to ensure the cleanliness of the gas. The side of the air inlet hole 13 protrudes from the upper wall of the shell 12 to prevent precipitation from flowing into the air inlet hole 13; the gas that floats into the shell 12 is filtered out through the clean parts to reduce the probability of floating objects floating into the shell 12. After the cover 163 covers the through window 162, the fan 155 changes the flow direction of the gas. The reverse blowing of the fan 155 can blow away the floating objects retained on the clean parts, ensuring the ability of the clean parts to filter out floating objects. During the rainfall period, the ambient temperature is not high, so the fan 155 blows air to the clean parts. During this period, the high-temperature gas can achieve the purpose of heat removal through the air inlet hole 13 without letting the gas in the shell 12 flow.

[0038] A liquid storage part 14 is arranged on the upper wall of the shell 12, and the bottom end of the liquid storage part 14 is movably connected to the heat removal part 15, and one end of the heat removal part 15 is movably connected to the swing closing part 16. The liquid storage part 14 accumulates precipitation and cooperates with the heat removal part 15 to pull the swing closing part 16 to close, thereby covering the opening of the shell 12.

[0039] The liquid storage part 14 includes two hollow rods 142 passing through the upper wall of the outer shell 12. The inside of the hollow rod 142 is slidably connected to the embedded rod 143. A spiral beryllium copper wire 144 is installed on the tail of the embedded rod 143. One end of the spiral beryllium copper wire 144 is fixedly connected to the embedded rod 143, and the other end of the spiral beryllium copper wire 144 is fixedly connected to the tail of the hollow rod 142.

[0040] The head of the embedded rod 143 is fixedly connected to the liquid storage shell 145, and the inside of the liquid storage shell 145 is slidably connected to the foam table 146. The foam table 146 is equipped with a curved screen 147. Drive plates 148 are installed on both sides of the curved screen 147. One end of the drive plate 148 extends to the tail of the liquid storage shell 145 and is fixedly connected to two drive tables 149. A displacement bar 1410 is connected and installed on one of the two drive tables 149. One end of the displacement bar 1410 is chamfered. The chamfered end of the displacement bar 1410 is variably connected to the empty space. In the circular groove 1421 on the outer wall of the core rod 142; the circular groove 1421 is a plurality of circular cavities arranged vertically at the same intervals, and the inner wall of each circular cavity in the circular groove 1421 gradually increases in radial span from low to high, ensuring that when the spiral beryllium copper wire 144 returns to its original shape to drive the embedded rod 143 to displace toward the head in the hollow rod 142, the chamfered end of the displacement bar 1410 is constantly displaced toward the head in the circular groove 1421, ensuring that the displacement bar 1410 returns to its initial position smoothly.

[0041] The square channel 1422 is rotatably connected to the front and back sides of the displacement bar 1410. A spiral beryllium copper wire X is arranged between the square channel 1422 and the displacement bar 1410. The spiral beryllium copper wire X can generate opposite torque when the rotation deformation is restored. The spiral beryllium copper wire X ensures the return of the displacement bar 1410 after the swing. Square holes are reserved on the opposite sides of the two square channels 1422. The compression rod 1423 passes through and is slidably connected to the square channel 1422. The head of the compression rod 1423 extends into the inside of the liquid storage shell 145 and is supported on the tail of the foam table 146. The tail of the compression rod 1423 is reserved with a through hole 1424. The through hole 1424 is pinned to a pin connection piece 1425. One of the pin connection pieces 1425 passes through the square channel 1422. The head of the square channel 1422 is fixedly connected to the liquid storage shell 145.

[0042] The tail of the compression rod 1423 is fixedly connected to an elastic rod 1426, and the elastic rod 1426 is fixedly connected to the tail of the inner wall of the square channel 1422, so as to return the compression rod 1423 to its initial position after being pressed toward the tail. After the precipitation ends, the water level in the liquid storage shell 145 slowly drops, and the foam platform 146 inside the liquid storage shell 145 moves to the tail of the inner wall of the liquid storage shell 145, and then compresses the compression rod 1423, so that the compression rod 1423 moves toward the tail, compressing one end of the through hole 1424 to move and separate from the inside of the buckle strip 1427, releasing the end constrained by the buckle strip 1427; in this way, the embedded rod 143 moves toward the rear due to the elastic recovery characteristics of the spiral beryllium copper wire 144. The head is displaced, so that the top connecting rod 1510 returns to its original position due to the elastic recovery characteristics of the elastic rod 165, and the traction cover 163 swings to open the through window 162, and the fan 155 in the traction coupling seat 154 swings back to its original position, allowing the fan 155 to deliver gas to the opened through window 162. In this way, the purpose of returning the top connecting rod 1510 to its original position is achieved, ensuring that the shell 12 blocks and covers the through window 162 when there is severe rainfall.

[0043] When the liquid level in the liquid storage shell 145 is gradually reduced to the minimum, the pressing rod 1423 starts to return to the initial position to prevent the through window 162 from opening during the period when the rainfall is strong or weak and has not completely ended, causing the components inside the shell 12 to be eroded by the liquid.

[0044] The upper wall of the housing 12 is equipped with a buckle strip 1427 , which is at the tail end of the pressing rod 1423 .

[0045] The heat removal part 15 includes a motor 152 mounted on the inner wall of the outer shell 12. One end of the output end of the motor 152 is fixedly connected to a rod body 153 with a reserved thread. The side of the rod body 153 is slidably connected to a connecting seat 154. A fan 155 is mounted on the connecting seat 154. A disk 156 with a plurality of reserved teeth is fixedly connected to the transmission rod of the fan 155. The disk 156 and the rod body 153 are engaged with each other.

[0046] A second disc 157 with a plurality of teeth is mounted on the rod body 153, one end of the second disc 157 is fixedly connected to the coupling seat 154, a third disc 158 with a plurality of teeth is engaged with the second disc 157, the outer wall of the third disc 158 is engaged with a ring body 159 with a plurality of teeth in the inner ring, and the ring body 159 is fixedly connected to the head area of ​​the inner wall of the liquid storage part 14. The second disc 157 and the motor 152 can rotate with each other.

[0047] The disc three 158 is rotatably connected to the top connecting rod 1510, which is installed on the rod body 153, and one end of the top connecting rod 1510 is connected to the tail of the embedded rod 143.

[0048] The swing closing portion 16 includes a through window 162 reserved on the outer shell 12, in which five cover plates 163 are pinned. The rod body 153 is installed at an angle, and one end of the five cover plates 163 is pinned to a pressing plate 164. One side of the pressing plate 164 is movably connected to the end of the top connecting rod 1510 farther from the embedded rod 143.

[0049] The head of the pressing piece 164 is movably connected to the second elastic rod 165 , and the second elastic rod 165 is assembled on the inner wall of the shell 12 .

[0050] The elastic rod comprises an outer fixed coupling tube and an inner rod, one end of the inner rod is inserted into the outer fixed coupling tube, and a spiral beryllium copper wire X is arranged between the inserted end of the inner rod and the outer fixed coupling tube, so that the elastic rod has the ability to return to its original position.

[0051] Both the front and back sides of the driving plate 148 are slidably connected to the constraint plate 18, and the constraint plate 18 is fixedly connected to the liquid storage shell 145.

[0052] The connecting seat 154 includes two V-shaped bar barrels 1542, and the two V-shaped bar barrels 1542 are slidably connected to the rod body 153. A connecting barrel 1543 is connected between the two V-shaped bar barrels 1542, and the two connecting barrels 1543 are slidably connected to the driving rod of the fan 155.

[0053] The upper wall of the liquid storage shell 145 is mirror-fixed with the bending piece 19.

[0054] The specific implementation method is as follows: in the absence of precipitation, the motor 152 drives the fan 155 to operate to transport the gas in the shell 12 out, and the high-temperature gas generated during the operation of the components in the shell 12 is discharged through the inclined open rod 153, ensuring the temperature control and heat removal of the shell 12 during long-term operation.

[0055] During precipitation, the precipitation is gathered together through the liquid storage shell 145 and discharged through the side discharge hole, so as to judge the strength of the precipitation. When the precipitation is not strong, the foam platform 146 in the liquid storage shell 145 cannot move toward the head, thus ensuring the normal shape of the through window 162;

[0056] During heavy rainfall, the amount of liquid in the liquid storage shell 145 gradually increases. During the period when the traction foam platform 146 slowly moves toward the head, the driving platform 149 at the tail of the foam platform 146 drives one end of the displacement bar 1410 to swing and deviate, so that the other end of the displacement bar 1410 is separated from the circular groove 1421, and the top contact pressure between the displacement bar 1410 and the circular groove 1421 is released. At this time, the embedded rod 143 accumulates precipitation in the liquid storage shell 145. When the hollow rod 142 moves toward the tail, the spiral beryllium copper wire 144 has a slowing function. During the displacement of the embedded rod 143 toward the tail, one end of the top connecting rod 1510 is driven to swing and compress the compression plate 164 to move, and then the cover plate 163 is pulled to swing to weaken the opening range of the through window 162, so as to prevent the precipitation from flowing into the inside of the housing 12 through the through window 162 during the period of heavy precipitation, so that the structure inside the housing 12 is eroded by the precipitation;

[0057] During the swinging of the top connecting rod 1510, the disk 3 158 on the top connecting rod 1510 is pulled to rotate on the inner wall of the ring body 159, thereby pulling the disk 2 157 and the V-shaped bar barrel 1542 connected to one end of the disk 2 157 to rotate, so that the fan 155 swings and blows air toward the air inlet hole 13 above the fan 155, and the normal temperature control and heat removal of the structure inside the shell 12 is ensured through the air inlet hole 13;

[0058] When the liquid storage shell 145 accumulates precipitation, the foam platform 146 in the liquid storage shell 145 moves toward the head and no longer presses the head of the pressure rod 1423. The pressure rod 1423 moves toward the head due to the elasticity of the elastic rod 1426, and the pulling pin connecting piece 1425 swings to increase the length of one end of the pin connecting piece 1425 protruding from the square channel 1422. During the period when the liquid storage shell 145 moves toward the tail, the square channel 1422 at the tail of the liquid storage shell 145 is pulled to move toward the tail, so that one end of the square channel 1422 is embedded in the buckle strip 1427.

[0059] After the precipitation ends, the water level in the liquid storage shell 145 slowly drops, and the foam platform 146 in the liquid storage shell 145 moves to the tail of the inner wall of the liquid storage shell 145 to press the pressing rod 1423, so that the pressing rod 1423 moves toward the tail to press the end of the through hole 1424 to move and separate from the inside of the buckle strip 1427, releasing the end constrained by the buckle strip 1427; in this way, the embedded rod 143 moves toward the tail due to the elastic recovery characteristics of the spiral beryllium copper wire 144. The head is displaced, so that the top connecting rod 1510 returns to its original position due to the elastic recovery characteristics of the elastic rod 165, and the traction cover 163 swings to open the through window 162, and the fan 155 in the traction coupling seat 154 swings back to its original position, allowing the fan 155 to deliver gas to the opened through window 162. In this way, the purpose of returning the top connecting rod 1510 to its original position is achieved, ensuring that the shell 12 covers the through window 162 when rainfall is severe.
