[0033] Example 1

[0034] Reference Figures 1-3 This is the first embodiment of the present invention. This embodiment provides a moisture-proof electrical cabinet for an electrical system, which includes a connecting component 100, a main cabinet component 200, and a side box component 300. It can seal the electrical cabinet while also allowing air to circulate through it, preventing the electrical cabinet from overheating and getting damp, and keeping the inside of the electrical cabinet ventilated and dry.

[0035] Specifically, the connecting assembly 100 includes a first fixing plate 101, an upper sealing member 102, a lower sealing member 103, and an air inlet pipe 104. The air inlet pipe 104 passes through and connects to the center of the first fixing plate 101. The lower sealing member 103 is fixedly connected to the bottom of the air inlet pipe 104, and the upper sealing member 102 is disposed at the top of the air inlet pipe 104. The connecting assembly 100 connects the main cabinet assembly 200 and the side box assembly 300, while ensuring that the main cabinet assembly 200 can receive dry air blown out by the side box assembly 300 from the air inlet pipe 104. The first fixing plate 101 is set at the upper part of the middle of the side of the main cabinet assembly 200. The bottom of the upper sealing member 102 and the top of the lower sealing member 103 both have semi-circular notches. The notches and contact surfaces are covered with a soft rubber coating to ensure airtightness. The upper sealing member 102 and the lower sealing member 103 together cover the air inlet pipe 104, and the contact surface of the upper sealing member 102 and the lower sealing member 103 is longer than the air inlet pipe 104.

[0036] Specifically, the main cabinet assembly 200 is located on one side of the connecting assembly 100, including the main cabinet 201 and the side panel 202. The main cabinet 201 is located on one side of the first fixed plate 101, and the side panel 202 is located at the bottom of the connecting assembly 100. The side panel 202 and the main cabinet 201 are fixedly connected. The main cabinet assembly 200 includes the necessary facilities for various electrical cabinets. The main cabinet 201 is used to house these facilities. At the same time, the connecting assembly 100 is located on one side of the main cabinet 201, and a one-way vent valve is provided on the other side. The side panel 202 is used to fix the side box assembly 300. The top of the side panel 202 has a long groove for the side box assembly 300 to move horizontally, and the bottom has reinforcing ribs for fixation.

[0037] Specifically, the side box assembly 300 is located on the other side of the connecting assembly 100, including the side box 301 and the bottom wheel 302. The side box 301 is located on the top of the side plate 202, and the bottom wheel 302 is located on the bottom of the side box 301. The side box assembly 300 includes drying equipment and ventilation equipment, etc., which are installed in the side box 301. The bottom wheel 302 and the long groove on the top of the side plate 202 are matched. When the side box assembly 300 is connected to the main cabinet assembly 200 through the connecting assembly 100, it dries the outside air and then blows it into the main cabinet assembly 200 through the air inlet pipe 104. The dried air is blown in from one side of the connecting assembly 100 of the main cabinet 201 and blown out from the other side through the one-way air outlet valve. This can remove the air inside the cabinet that may contain water vapor and also ventilate and remove the hot air inside the cabinet.

[0038] In use, the connecting component 100 connects the main cabinet component 200 and the side box component 300, while ensuring that the main cabinet component 200 can receive dry air blown out by the side box component 300 from the air inlet pipe 104. The first fixing plate 101 is set at the upper middle part of the side of the main cabinet component 200. The bottom of the upper seal 102 and the top of the lower seal 103 both have semi-circular notches. The notches and contact surfaces are covered with a soft rubber coating to ensure airtightness. The upper seal 102 and the lower seal 103 together cover the air inlet pipe 104, and the contact surface of the upper seal 102 and the lower seal 103 is longer than the air inlet pipe 104. The main cabinet assembly 200 includes the necessary facilities for various electrical cabinets. The main cabinet 201 is used to house these facilities. One side of the main cabinet 201 has a connecting assembly 100, and the other side has a one-way exhaust valve. The side plate 202 is used to fix the side box assembly 300. The top of the side plate 202 has a long groove for the side box assembly 300 to slide horizontally, and the bottom has reinforcing ribs for fixation. The side box assembly 300 includes drying and ventilation equipment, etc., and is installed in the side box 301. The bottom wheel 302 and the long groove on the top of the side plate 202 cooperate. When the side box assembly 300 is connected to the main cabinet assembly 200 through the connecting assembly 100, it dries the outside air and then blows it into the main cabinet assembly 200 through the air inlet pipe 104. The dried air is blown in from one side of the connecting assembly 100 of the main cabinet 201 and blown out from the one-way exhaust valve on the other side. This not only removes any potentially water-vapor-laden air inside the cabinet but also provides ventilation and removes hot air from inside the cabinet.

[0039] Example 2

[0040] Reference Figures 1-9 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0041] To facilitate the description of different states in this invention, the state when the connecting component 100 is not connected to the main cabinet component 200 and the side box component 300 is referred to as the default state, and the state after connection is referred to as the connected state.

[0042] Specifically, the connecting assembly 100 also includes a reset spring 105, which is disposed between the upper seal 102 and the lower seal 103. The bottom of the upper seal 102 is provided with a first groove H1, and the top of the lower seal 103 is provided with a second groove H2. The reset spring 105 is disposed between the first groove H1 and the second groove H2. The reset spring 105 will lift the upper seal 102 by default.

[0043] Specifically, the connecting assembly 100 also includes a pressure-bearing arc block 106, which is disposed on the top of the upper seal 102. The first fixing plate 101 also includes a third groove H3, which is disposed at the top center of the first fixing plate 101. The pressure-bearing arc block 106 includes a front, a bottom, a rear, and two sides. The front is arc-shaped, the bottom is fixed to the top of the upper seal 102, and the rear is in contact with the center of the first fixing plate 101. The third groove H3 is covered by the rear of the pressure-bearing arc block 106 in the default state.

[0044] Specifically, the connecting assembly 100 also includes a first limiting plate 107 and a second limiting plate 108. The first limiting plate 107 is disposed on one side of the pressure arc block 106, and the second limiting plate 108 is disposed on the other side of the pressure arc block 106. The first limiting plate 107 is provided with a first limiting through hole L1, a limiting groove L2, a limiting arc block 107a, and a limiting spring 107b. The first limiting through hole L1 penetrates through the side of the first limiting plate 107. The limiting groove L2 is disposed inside the first limiting through hole L1. One end of the limiting spring 107b is disposed inside the limiting groove L2, and the other end is connected to the limiting arc block 107a. The second limiting plate 108 is provided with a second limiting through hole R1 on its side. The first limiting through hole L1 of the first limiting plate 107 and the second limiting through hole R1 on the side of the second limiting plate 108 correspond to each other.

[0045] Specifically, the connecting assembly 100 also includes a first clamping post 109, a limiting ring 110, and a second clamping post 111. The first clamping post 109 passes through the first limiting through hole L1, and the second clamping post 111 passes through the second limiting through hole R1. The limiting ring 110 is rotatably connected to the first clamping post 109 and the second clamping post 111. The side of the first clamping post 109 is provided with a fourth groove H4. The fourth groove H4 of the first clamping post 109 is a quarter cylinder. In the default state, the position of the first clamping post 109 is higher than that of the limiting arc block 107a.

[0046] Specifically, the connecting assembly 100 also includes a tensioning handle 112, which is located on one side of the first clamping post 109. When the tensioning handle 112 is rotated, it will drive the first clamping post 109 to rotate.

[0047] Specifically, the connecting assembly 100 also includes a second fixing plate 113 and an air outlet pipe 114. The second fixing plate 113 is located opposite the first fixing plate 101, and the air outlet pipe 114 passes through and connects to the center of the second fixing plate 113. The second fixing plate 113 is fixed to one side of the side box assembly 300, and the air outlet pipe 114 is connected to the ventilation device inside the side box assembly 300.

[0048] Specifically, the connecting assembly 100 also includes a fixing post 115 and a clamping plate 116. One end of the fixing post 115 passes through the limiting ring 110, and the other end is rotatably connected to the bottom of the clamping plate 116. One end of the fixing post 115 can rotate around the bottom connection of the clamping plate 116, and the clamping plate 116 can move up and down or be fixed. The other end of the fixing post 115 is in contact with the pressure arc block 106 in the default state.

[0049] In use, under default conditions, the return spring 105 will push up the upper seal 102, the pressure arc block 106 will cover the third groove H3, and the first clamping post 109 will be higher than the limiting arc block 107a. To connect the side box assembly 300 and the main cabinet assembly 200, first move the side box assembly 300 to align the air outlet pipe 114 and the air inlet pipe 104, insert the fixing post 115 into the limiting ring 110, and then move the side box assembly 300 closer to the main cabinet assembly 200. At this time, the fixing post 115 will be close to the main cabinet assembly 200, and the pressure arc block 106 will be lowered. Block 106 will move downward under the pressure of the end of the fixing post 115, slowly merging the upper seal 102 and the lower seal 103, and slowly clamping the air inlet pipe 104 and the air outlet pipe 114. As the compressed block 106 moves downward, the third groove H3 will slowly be exposed. Then the fixing post 115 will be inserted into the third groove H3. At this time, it is no longer necessary to bring the side box assembly 300 close to the main cabinet assembly 200. The force can be released and the return spring 105 is compressed. However, since the fixing post 115 is in the third groove H3, it cannot lift the upper seal 102.

[0050] At this point, the clamping plate 116 is pressed down. Since one end of the fixing post 115 is rotatably connected to the bottom of the clamping plate 116 and the other end is in the third groove H3, the fixing post 115 rotates around the fulcrum in the third groove H3. At the same time, the pressure-bearing arc block 106 continues to move downward under the pressure from the side of the fixing post 115. Since the contact surfaces and arc surfaces of the upper seal 102 and the lower seal 103 are both made of rubber, the upper seal 102 and the lower seal 103 continue to move closer, wrapping the air inlet pipe 104 and the air outlet pipe 114 closer together, further enhancing the airtightness. Meanwhile, since the fixing post 115 is inserted into the limiting ring 110, the limiting ring 110 is driven downward when the fixing post 115 rotates. The position of the first clamping post 109 moves down from above the limiting arc block 107a, pressing the limiting arc block 107a into the limiting groove L2. The limiting spring 107b is compressed by force, and the first clamping post 109 continues to move down. The fourth groove H4 on the side of the first clamping post 109 moves down to the position of the limiting arc block 107a. The limiting spring 107b releases its elastic force, locking the limiting arc block 107a in the fourth groove H4. At this time, the clamping plate 116 can no longer be pressed down. The stress between the upper seal 102 and the lower seal 103 is very high, but because the limiting arc block 107a is locked in the fourth groove H4, the limiting ring 110 cannot move up, and therefore the fixing post 115 cannot be pushed back.

[0051] When the connection needs to be opened, rotate the tension handle 112 by a certain angle. The side of the fourth groove H4 will push the limiting arc block 107a back, and the limiting spring 107b will be compressed. The stress between the upper seal 102 and the lower seal 103 will be transferred to the first clamping column 109, causing the first clamping column 109 to move upward. At this time, lift the clamping plate 116, and the fixing column 115 will move upward and disengage from the third groove H3. The main cabinet assembly 200 and the side box assembly 300 will separate and return to the default position.

[0052] The connecting component 100 tightly connects the main cabinet component 200 and the side box component 300, while ensuring that the main cabinet component 200 can receive dry air blown out by the side box component 300 from the air inlet pipe 104. The first fixing plate 101 is set at the upper part of the middle of the side of the main cabinet component 200. The bottom of the upper seal 102 and the top of the lower seal 103 both have semi-circular notches. The notches and contact surfaces are covered with a soft rubber coating to ensure airtightness. The upper seal 102 and the lower seal 103 together cover the air inlet pipe 104, and the contact surface of the upper seal 102 and the lower seal 103 is longer than the air inlet pipe 104. The main cabinet assembly 200 includes the necessary facilities for various electrical cabinets. The main cabinet 201 is used to house these facilities. One side of the main cabinet 201 has a connecting assembly 100, and the other side has a one-way exhaust valve. The side plate 202 is used to fix the side box assembly 300. The top of the side plate 202 has a long groove for the side box assembly 300 to slide horizontally, and the bottom has reinforcing ribs for fixation. The side box assembly 300 includes drying and ventilation equipment, etc., and is installed in the side box 301. The bottom wheel 302 and the long groove on the top of the side plate 202 cooperate. When the side box assembly 300 is connected to the main cabinet assembly 200 through the connecting assembly 100, it dries the outside air and then blows it into the main cabinet assembly 200 through the air inlet pipe 104. The dried air is blown in from one side of the connecting assembly 100 of the main cabinet 201 and blown out from the one-way exhaust valve on the other side. This not only removes any potentially water-vapor-laden air inside the cabinet but also provides ventilation and removes hot air from inside the cabinet.

[0053] Example 3

[0054] Reference Figures 1-9 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0055] Specifically, the clamping plate 116 includes a clamping plate 116a, a clamping block 116b, and a connecting post 116c. The clamping block 116b is located at the bottom center of the clamping plate 116a. The connecting post 116c is rotatably connected to the clamping block 116b and is connected through the fixing post 115.

[0056] Specifically, the top of the second fixing plate 113 is provided with a fifth groove H5, and the fastening block 116b is disposed in the fifth groove H5. The fastening plate 116 can move up and down along the fifth groove H5.

[0057] In use, under default conditions, the return spring 105 will push up the upper seal 102, the pressure arc block 106 will cover the third groove H3, and the first clamping post 109 will be higher than the limiting arc block 107a. To connect the side box assembly 300 and the main cabinet assembly 200, first move the side box assembly 300 to align the air outlet pipe 114 and the air inlet pipe 104, insert the fixing post 115 into the limiting ring 110, and then move the side box assembly 300 closer to the main cabinet assembly 200. At this time, the fixing post 115 will be close to the main cabinet assembly 200, and the pressure arc block 106 will be lowered. Block 106 will move downward under the pressure of the end of the fixing post 115, slowly merging the upper seal 102 and the lower seal 103, and slowly clamping the air inlet pipe 104 and the air outlet pipe 114. As the compressed block 106 moves downward, the third groove H3 will slowly be exposed. Then the fixing post 115 will be inserted into the third groove H3. At this time, it is no longer necessary to bring the side box assembly 300 close to the main cabinet assembly 200. The force can be released and the return spring 105 is compressed. However, since the fixing post 115 is in the third groove H3, it cannot lift the upper seal 102.

[0058] The clamping plate 116 can move up and down along the fifth groove H5. When the clamping plate 116 is pressed down, since one end of the fixing post 115 is rotatably connected to the bottom of the clamping plate 116 and the other end is in the third groove H3, the fixing post 115 rotates around the fulcrum in the third groove H3. At the same time, the pressure-bearing arc block 106 continues to move downward under the pressure from the side of the fixing post 115. Since the contact surface and arc surface of the upper seal 102 and the lower seal 103 are both made of rubber, the upper seal 102 and the lower seal 103 continue to move closer, wrapping the air inlet pipe 104 and the air outlet pipe 114 closer together, further enhancing the airtightness. At the same time, since the fixing post 115 is inserted in the limiting ring 110, the limiting ring 110 is in the fixing post. When 115 rotates, it is driven to move downwards. The position of the first clamping column 109 moves down from above the limit arc block 107a, pressing the limit arc block 107a into the limit groove L2. The limit spring 107b is compressed by force, and the first clamping column 109 continues to move downwards. The fourth groove H4 on the side of the first clamping column 109 moves down to the position of the limit arc block 107a. The limit spring 107b releases its elastic force, locking the limit arc block 107a in the fourth groove H4. At this time, the clamping plate 116 can no longer be pressed down. The stress between the upper seal 102 and the lower seal 103 is very high. However, because the limit arc block 107a is locked in the fourth groove H4, the limit ring 110 cannot move upwards, and therefore cannot push the fixing column 115 back.

[0059] When the connection needs to be opened, rotate the tension handle 112 by a certain angle. The side of the fourth groove H4 will push the limiting arc block 107a back, and the limiting spring 107b will be compressed. The stress between the upper seal 102 and the lower seal 103 will be transferred to the first clamping column 109, causing the first clamping column 109 to move upward. At this time, lift the clamping plate 116, and the fixing column 115 will move upward and disengage from the third groove H3. The main cabinet assembly 200 and the side box assembly 300 will separate and return to the default position.

[0060] The connecting component 100 tightly connects the main cabinet component 200 and the side box component 300, while ensuring that the main cabinet component 200 can receive dry air blown out by the side box component 300 from the air inlet pipe 104. The first fixing plate 101 is set at the upper part of the middle of the side of the main cabinet component 200. The bottom of the upper seal 102 and the top of the lower seal 103 both have semi-circular notches. The notches and contact surfaces are covered with a soft rubber coating to ensure airtightness. The upper seal 102 and the lower seal 103 together cover the air inlet pipe 104, and the contact surface of the upper seal 102 and the lower seal 103 is longer than the air inlet pipe 104. The main cabinet assembly 200 includes the necessary facilities for various electrical cabinets. The main cabinet 201 is used to house these facilities. One side of the main cabinet 201 has a connecting assembly 100, and the other side has a one-way exhaust valve. The side plate 202 is used to fix the side box assembly 300. The top of the side plate 202 has a long groove for the side box assembly 300 to slide horizontally, and the bottom has reinforcing ribs for fixation. The side box assembly 300 includes drying and ventilation equipment, etc., and is installed in the side box 301. The bottom wheel 302 and the long groove on the top of the side plate 202 cooperate. When the side box assembly 300 is connected to the main cabinet assembly 200 through the connecting assembly 100, it dries the outside air and then blows it into the main cabinet assembly 200 through the air inlet pipe 104. The dried air is blown in from one side of the connecting assembly 100 of the main cabinet 201 and blown out from the one-way exhaust valve on the other side. This not only removes any potentially water-vapor-laden air inside the cabinet but also provides ventilation and removes hot air from inside the cabinet.
