DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-9 As shown, the present invention provides a self-moving anti-seepage outdoor power distribution cabinet, including a power distribution cabinet 1, a cabinet door 101 is provided on the power distribution cabinet 1, and a plurality of evenly distributed heat dissipation and ventilation slots 104 are provided on both side walls of the power distribution cabinet 1, each heat dissipation and ventilation slot 104 is in a straight line shape, and the heat dissipation and ventilation slot 104 is inclined, and the inclination direction of the heat dissipation and ventilation slot 104 is set from low to high along the direction toward the inside of the power distribution cabinet 1. By arranging the heat dissipation and ventilation slot 104 in an inclined manner, it is possible to prevent wind and rain from entering the inside of the power distribution cabinet 1 from the heat dissipation and ventilation slot 104. In the case of strong wind and rainy weather, but without accumulated rain, the power distribution cabinet 1 itself has a certain protective effect.

[0025] A base 2 for fixedly supporting the distribution cabinet 1 is provided at the bottom, and a control panel 8 is provided on the distribution cabinet 1. A telescopic sheath 4 is provided on the outer side of the distribution cabinet 1 for moving up and down. The bottom end of the telescopic sheath 4 is fixedly sealed and connected to the base 2. The cross-sectional shape of the telescopic sheath 4 is wavy. The telescopic sheath 4 is made of rubber material. In actual application, the thickness of the telescopic sheath 4 is 1mm-6mm. The top of the telescopic sheath 4 is connected to a suspension ring 3 for providing buoyancy to float on the water surface. The cross-sectional shape of the suspension ring 3 is rectangular, and the interior of the suspension ring 3 is in the shape of an airbag.

[0026] When the suspension ring 3 floats up and down due to the change of water surface height, the suspension ring 3 can drive the telescopic sheath 4 to move up and down and telescope, wherein an anti-seepage chamber 9 is formed between the inner side of the telescopic sheath 4, the outer side of the distribution cabinet 1 and the upper side of the base 2, and a rain shield 102 is fixedly provided on the upper side of the distribution cabinet 1, and the outer edge of the rain shield 102 protrudes from the outer wall of the distribution cabinet 1. When the suspension ring 3 rises to the highest position, the top side of the suspension ring 3 and the lower edge of the rain shield 102 are sealed and abutted against each other, and the anti-seepage chamber 9 is in a sealed state, and the upper side of the anti-seepage chamber 9 is in an open state. In actual application, when the suspension ring 3 rises to the highest position, the rain shield 102 can close the upper opening of the anti-seepage chamber 9, thereby sealing the anti-seepage chamber 9 as a whole, so that the anti-seepage chamber 9 is in a vacuum chamber state.

[0027] The anti-seepage chamber 9 is provided with a drainage component 6 capable of discharging the water inside the chamber, and the top side of the power distribution cabinet 1 is provided with an active limiting structure for supporting and limiting the suspension ring 3 at the highest position. The water in the anti-seepage chamber 9 can be discharged in time through the drainage component 6 to prevent water from accumulating in the anti-seepage chamber 9 and penetrating the power distribution cabinet 1. The active limiting structure can actively move the suspension ring 3 up to the highest position to achieve sealing protection for the anti-seepage chamber 9 when it is known in advance that there will be a heavy rainstorm or flood warning. At this time, the active limiting structure can realize the fixed maintenance of the suspension ring 3 when it rises and moves to the highest position.

[0028] See the instruction manual Figure 6 As shown, a support collar 301 is provided on the inner side of the suspension ring 3, the lower side of the support collar 301 and the upper side of the telescopic sheath 4 are fixedly sealed and connected to each other, the outer side of the support collar 301 and the inner side of the suspension ring 3 are connected to each other through a plurality of connecting belt rings 302, the connecting belt rings 302 are made of elastic rubber material, and the cross-sectional shape of the connecting belt ring 302 is in the shape of an arc. In practical applications, when the suspension ring 3 rises and falls due to the buoyancy of the water surface, the suspension ring 3 will also shake with the waves due to the impact of the water surface. At this time, in order to avoid the rigid impact on the support collar 301 affecting the sealing performance, the connecting belt ring 302 provided between the support collar 301 and the suspension ring 3 can play a certain buffering role.

[0029] Two or more guide rods 5 are symmetrically distributed around the distribution cabinet 1 on both sides. The upper and lower ends of each guide rod 5 are fixedly connected to the rain shield 102 and the base 2 respectively. The inner wall of the support ring 301 is fixedly provided with a support ear 303 corresponding to the guide rod 5 one by one. The support ear 303 is penetrated with a guide slide hole that cooperates with the guide rod 5. Through the above-mentioned specific structural design, when the suspension ring 3 rises and falls due to the buoyancy of the water surface, the support ring 301 moves up and down with the suspension ring 3, and the guide rod 5 can guide the support ring 301 to move up and down, so that the support ring 301 can be accurately docked and sealed with the rain shield 102 to avoid water seepage in the gap caused by misalignment.

[0030] A second sealing ring 304 is fixedly provided on the upper side of the support collar 301, and a first sealing ring 105 is fixedly provided along the edge of the lower side of the rain shield 102. The cross-sectional shapes of the first sealing ring 105 and the second sealing ring 304 are both right-angled trapezoids. When the suspension ring 3 and the rain shield 102 are sealed against each other, the inclined surfaces of the first sealing ring 105 and the second sealing ring 304 are in contact with each other, and a sealing gasket 306 is provided on the inner side of the second sealing ring 304. The bottom side edge of the sealing gasket 306 and the inner side wall of the second sealing ring 304 are fixedly sealed and connected to each other. Then, the upper edge of the sealing gasket 306 protrudes above the upper height position of the second sealing retaining ring 304. The sealing gasket 306 is made of rubber material and has a C-shaped cross-section. A water outlet channel 305 is provided at the connection between the second sealing retaining ring 304 and the supporting ring 301. The water outlet channel 305 is used to guide water and is used to guide the water that penetrates between the first sealing retaining ring 105 and the second sealing retaining ring 304. The sealing gasket 306 plays a sealing and shielding role for the water that penetrates between the first sealing retaining ring 105 and the second sealing retaining ring 304.

[0031] A support frame 201 is fixedly provided on the upper side of the base 2, and the bottom side of the power distribution cabinet 1 is fixedly connected to the upper side of the support frame 201 by bolts. When the bottom side of the suspension ring 3 drops to the lowest position and contacts the upper surface of the base 2, the lug 303 and the upper surface of the support frame 201 abut against each other, and a plurality of mounting holes 202 are provided on the base 2. In practical applications, the support frame 201 plays a supporting role in placing the telescopic sheath 4, and is used to place the power distribution cabinet 1 in a completely exposed state, and the power distribution cabinet 1 can also be raised to a certain height, and the reserved space also plays a certain role in preventing water infiltration.

[0032] See the instruction manual Figure 4 , 5 As shown in Figure 6, the drainage assembly 6 includes a water pump 601 fixedly mounted on the base 2, the outer cover of the water pump 601 is provided with a protective net 602 for filtering the incoming water, the water outlet of the water pump 601 is connected to two drainage pipes 603, each guide rod 5 is provided with a water passage 604, the two drainage pipes 603 are respectively connected to the water passage 604 in the two guide rods 5, drainage holes 605 are provided inside the two sides of the rain shield 102, the two drainage holes 605 are respectively connected to the water passage 604 in the two guide rods 5, and the output end of the control panel 8 is electrically connected to the input end of the water pump 601. A liquid level sensor 7 for detecting the liquid level inside the anti-seepage chamber 9 is provided on the bottom side of the power distribution cabinet 1, and the output end of the liquid level sensor 7 is electrically connected to the input end of the control panel 8. Through the coordination and cooperation between the drainage component 6, the liquid level sensor 7 and the control panel 8, the accumulated water in the anti-seepage chamber 9 can be automatically discharged to prevent the accumulated water from rising to the cabinet door and the heat dissipation ventilation groove 104 and causing penetration.

[0033] See the instruction manual Figure 2 As shown, the active limit structure includes an electric telescopic rod 10 fixedly arranged on the top side of the power distribution cabinet 1. The electric telescopic rod 10 adopts a double-axis electric push rod. The two push rod heads of the double-axis electric push rod respectively pass through the outer wall of the power distribution cabinet 1 and are fixedly connected to the limit column 11. The inner wall of the support collar 301 is provided with a limit groove 12 that cooperates with the limit column 11. The outer shape of the limit column 11 is a truncated cone shape, and the depth of the limit groove 12 in the up and down direction is greater than the maximum radial direction of the limit column 11. When the suspension ring 3 and the rain shield 102 are sealed and abutted against each other, the upper side of the limit column 11 and the upper side of the inner part of the limit groove 12 abut against each other. Through the above-mentioned specific structural design, when the suspension ring 3 is pulled up to the highest position, the two push rods of the electric telescopic rod 10 are extended, thereby driving the two limit columns 11 to be inserted into the limit grooves 12. At this time, a certain distance will be reserved between the bottom side of the limit column 11 and the bottom side of the limit groove 12, so that the suspension ring 3 can continue to provide the reserved space for the buoyancy of the support ring 301 to push upward, thereby improving the sealing performance.

[0034] Working principle: Under normal conditions, that is, when there is no rain or water accumulation, the suspension ring 3 is located on the upper side of the base 2 under the action of its own gravity, as shown in the attached manual. Figure 8 As shown, the cabinet door 101 of the power distribution cabinet 1 is in a completely exposed state, which does not affect the operation of the power distribution cabinet 1 under normal conditions. For example, when a staff member opens the cabinet door 101 to operate inside the power distribution cabinet 1, the heat dissipation ventilation slots 104 are also in a completely exposed state, which does not affect the ventilation and heat dissipation inside the power distribution cabinet 1; When it rains and water accumulates, as the water surface rises and falls, the suspension ring 3 can rise and fall with the water surface, and in the process of the suspension ring 3 rising and falling, the suspension ring 3 drives the telescopic sheath 4 to expand and contract, so that the water surface is always lower than the upper side height of the suspension ring 3, and the telescopic sheath 4 is used to block the water to prevent the water from entering the anti-seepage chamber 9, so that no matter how high the water surface is, the distribution cabinet 1 can always be prevented from being immersed in the water. When the water height exceeds the rain shield 102, the suspension ring 3 rises to the highest position under the limit of the rain shield 102, and at this time, the first sealing retaining ring 105 and the second sealing retaining ring 304 abut against each other to seal, so as to achieve the overall sealing of the anti-seepage chamber 9, so that a sealed cavity is formed inside the anti-seepage chamber 9, and the distribution cabinet 1 is sealed and protected. Even if the water surface continues to rise, under the action of the rising buoyancy of the suspension ring 3, the first sealing retaining ring 105 and the second sealing retaining ring 304 can always achieve sealing cooperation to prevent the water from being immersed in the anti-seepage chamber 9; In windy weather, rainwater will enter the anti-seepage chamber 9 in the telescopic sheath 4 under the influence of wind, and the water in the anti-seepage chamber 9 will gradually accumulate and rise. At this time, the liquid level sensor 7 can detect the liquid level in the anti-seepage chamber 9. After the liquid level in the anti-seepage chamber 9 reaches a certain value, the liquid level sensor 7 transmits the detected electrical signal to the control panel 8. The control panel 8 controls the water pump 601 of the drainage component 6 to open, and the water pump 601 discharges the water in the anti-seepage chamber 9 through the drainage pipe 603, the water channel 604 and the drainage channel 605 in turn.

[0035] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
