DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0027] A high voltage ring main unit based on moisture proof treatment, such as Figure 1 and Figure 2 As shown, it includes an outer shell 1, an outer door 2, a controller 21, a temperature sensor 31, an inner shell 3, an inner door 4, an exhaust fan 5, a heating mechanism and a dehumidification mechanism. The outer shell 1 is rotatably connected to the outer door 2 at the front right part, and the controller 21 is installed on the outer door 2. The inner shell 3 is slidably connected to the outer shell 1, and the temperature sensor 31 is installed on the upper left part of the inner shell 3. The temperature sensor 31 is electrically connected to the controller 21. The inner shell 3 can slide back and forth in the outer shell 1. The outer shell 1 can be removed by sliding forward, and there is a gap between the outer shell 1 and the inner shell 3, which is a separation space for separating moisture. The right front part of the inner shell 3 is rotatably connected with an inner door 4, and a plurality of exhaust fans 5 are evenly spacedly installed on the upper rear part of the outer shell 1, and the exhaust fans 5 can discharge the moisture in the outer shell 1 when they are operated. A heating mechanism for heating the outer shell 1 is provided on the outer shell 1, and a dehumidification mechanism for extracting moisture in the inner shell 3 is provided between the outer shell 1 and the inner shell 3.

[0028] like Figure 2 As shown, the heating mechanism includes a heating water tank 61, a support plate 62 and a heating pipe 63. The support plate 62 is connected to the bottom of the outer shell 1, and the heating water tank 61 is installed at the bottom of the support plate 62. The controller 21 is electrically connected to the heating water tank 61. The heating water tank 61 is filled with water. The top of the support plate 62 is connected to the heating pipe 63. The heating pipe 63 is close to the bottom of the outer shell 1. Both ends of the heating pipe 63 extend into the heating water tank 61. A water pump is installed in the heating water tank 61, and the water outlet end of the water pump is connected to the heating pipe 63.

[0029] like Figure 2As shown, the dehumidification mechanism includes an air outlet box 71, a connecting pipe 72 and an air guide fan 73. The lower parts of the left and right sides of the outer shell 1 are connected to the air outlet boxes 71. The bottom of the air outlet box 71 is an air outlet. The front and back sides of the bottom of the air outlet box 71 are equipped with air guide fans 73. The air outlet box 71 is connected with a connecting pipe 72. The connecting pipe 72 passes through the outer shell 1 and extends into the inner shell 3, so that the air guide fan 73 can operate to extract moisture in the inner shell 3 through the connecting pipe. A one-way valve is installed in the connecting pipe 72, and the air guide fan 73 can operate to extract moisture in the inner shell 3.

[0030] like Figure 3 As shown, a molecular sieve 11 is also included. Air inlets are opened on the upper parts of the left and right sides of the inner shell 3. The molecular sieve 11 is arranged at the air inlet to remove moisture. When the moisture in the inner shell 3 is discharged, the air inlet can take in air. At the same time, the hydrophilicity of the molecular sieve 11 can be used to dry the air passing through the molecular sieve 11.

[0031] When a high-voltage ring network cabinet is needed, the present high-voltage ring network cabinet can be used. When in use, the power equipment is installed in the inner shell 3, and the external air is isolated by the separation space between the inner shell 3 and the outer shell 1. When the outside is humid, there is also a separation space for separation, so as to achieve the effect of separating the air and preventing moisture. In the process of use, water can be added to the heating water tank 61 and the water can be heated. During heating, the temperature sensor 31 can detect the temperature inside the inner shell 3, and then control the heating water tank 61 to heat the water to the same temperature as the internal temperature of the inner shell 3, and then control the water pump to operate so that the hot water circulates in the heating pipe 63, thereby heating the outer shell 1 to heat the separation space, so that the air temperature in the separation space is consistent with the temperature inside the inner shell 3, avoiding temperature difference and causing the inner shell 3 can condense the moisture inside, and at the same time, the air guide fan 73 can be controlled to start to extract the moisture in the inner shell 3 through the connecting pipe 72. While dehumidifying, the air inlet can take in air, and the air intake can use the hydrophilicity of the molecular sieve 11 to dry the air passing through the molecular sieve 11, thereby further playing a moisture-proof role. In this way, the high-voltage ring network cabinet can be used, and during use, the separation space between the outer shell 1 and the inner shell 3 can be used to initially isolate the moisture from the outside, and the temperature of the inner shell 3 can be ensured to be consistent with the temperature at the separation space by heating, so as to prevent the temperature difference from causing moisture to condense in the inner shell. At the same time, the moisture in the inner shell 3 can be extracted by the operation of the air guide fan 73. During operation, if the parts inside the inner shell 3 need to be repaired, the inner shell 3 can be removed for repair.

[0032] like Figure 4As shown, a scraper mechanism is also included, which includes a small motor 80, a reciprocating screw 81, a scraper frame 83 and a sponge pad 84. The reciprocating screw 81 is rotatably connected to the left rear side of the outer shell 1, and a small motor 80 is installed on the top of the outer shell 1. The output shafts of the small motor 80 are respectively connected to the reciprocating screw 81 so that the small motor 80 can drive the reciprocating screw 81 to rotate. The reciprocating screw 81 is threadedly connected to the scraper frame 83, and the scraper frame 83 is slidably connected to the outer shell 1 to guide the scraper frame 83 through the outer shell 1. The scraper frame 83 is connected to a sponge pad 84 on the side close to the inner wall of the outer shell 1, so that the scraper frame 83 can absorb moisture attached to the inner wall of the outer shell 1 through the sponge pad 84 when sliding.

[0033] like Figure 5 and Figure 6 As shown, it also includes a moisture collection mechanism, which includes a collection box 91, a baffle plate 92 and a connecting pipe 93. The lower parts of the left and right sides of the outer shell 1 are slidably connected with the collection boxes 91, and the collection box 91 can be pulled out from the outer shell 1. A collection groove is opened in the lower part of the outer shell 1, and a baffle plate 92 is connected to the top of the collection groove. The baffle plate 92 is evenly spaced with leakage holes for water to pass through. The left and right sides of the collection groove are connected with connecting pipes 93, and the ends of the connecting pipes 93 are aligned with the inside of the collection box 91, so that the water in the collection groove can flow into the collection box 91 through the connecting pipes 93, so that the water attached to the inner wall of the outer shell 1 is collected by the collection box 91.

[0034] When using the present high-voltage ring network cabinet, if there is heavy moisture in the gap between the outer shell 1 and the inner shell 3, the moisture will adhere to the inner wall of the outer shell 1 to form water droplets. At this time, the small motor 80 can be controlled to drive the reciprocating screw 81 to rotate, thereby driving the scraper frame 83 to move downward. When moving downward, the scraper frame 83 drives the sponge pad 84 to move downward, thereby absorbing the water droplets attached to the inner wall of the outer shell 1 until the sponge pad 84 moves to the baffle plate 92. The baffle plate 92 can squeeze the sponge pad 84 and squeeze out the moisture adsorbed in the sponge pad 84. The squeezed water will fall into the collecting trough through the baffle plate 92, thereby collecting the water through the collecting trough, and the water in the collecting trough can flow into the collecting box 91 through the connecting pipe 93 to be collected by the collecting box 91. In this way, the water attached to the inner wall of the outer shell 1 can be collected. When the collected water needs to be poured out, the collecting box 91 can be pulled out, and then the water inside the collecting box 91 can be poured out.

[0035] like Figure 7-10As shown, it also includes a central storage mechanism, which includes a sliding plate 101, a guide frame 102, a rotating shaft 103, a connecting gear 1031, a sliding rack 104, an extrusion wheel 105, a transmission gear 106 and an elastic member 107. The sliding plate 101 is slidably connected to the lower front part of the outer shell 1, and the lower parts of the left and right sides of the inner shell 3 are connected to two symmetrically arranged guide frames 102. The bottom of the guide frame 102 is inclined. The middle of the lower part of the outer shell 1 is rotatably connected to the rotating shaft 103, and the two ends of the rotating shaft 103 are connected to the transmission gear 106. The middle part of the rotating shaft 103 is connected to the connecting gear 1031, and the middle of the top of the sliding plate 101 is open. A tooth groove 1032 is provided, and the sliding plate 101 is meshed with the connecting gear 1031 through the tooth groove 1032, so that the movement of the sliding plate 101 can rub the connecting gear 1031 to rotate through the tooth groove 1032, and an elastic member 107 is connected between the sliding plate 101 and the outer shell 1, and the elastic member 107 is a connecting spring. The lower parts of the left and right sides of the outer shell 1 are slidably connected with sliding racks 104, and the sliding racks 104 are meshed with the transmission gear 106. The top of the sliding rack 104 is rotatably connected with an extrusion wheel 105, and the movement of the extrusion wheel 105 can squeeze the inner shell 3 through the guide frame 102 to move, so that the inner shell 3 moves to the middle of the outer shell 1.

[0036] When the outer door 2 is closed, the outer door 2 will contact the sliding plate 101 and squeeze the sliding plate 101 to move backward, and the elastic member 107 will be compressed. When the sliding plate 101 moves backward, the connecting gear 1031 will be rotated by rubbing the tooth groove 1032. The connecting gear 1031 drives the rotating shaft 103 to rotate when rotating. The rotation of the rotating shaft 103 drives the transmission gears 106 on both sides to rotate. When the transmission gear 106 rotates, the sliding rack 104 moves upward when rotating. The sliding rack 104 moves upward and drives the extrusion wheel 105 to move upward. When the extrusion wheel 105 moves upward, it can contact the guide frame 102 and squeeze the guide frame 102 to move, thereby driving the inner shell 3 to move, so that the inner shell 3 is stored in the center of the outer shell 1, ensuring that the distance between the front and rear side walls of the inner shell 3 and the front and rear side walls of the outer shell 1 is consistent, so that the storage distance is consistent, thereby ensuring the overall isolation effect.
