Description

Technical Field

[0001] The invention relates to the technical field of distribution boxes, and in particular to a dehumidification device for a distribution box. Background Art

[0002] A distribution box is a device used for switching, controlling or protecting the power generation, transmission, distribution, energy conversion and consumption of power systems. It plays a very important role in the entire power industry. During normal operation, it can connect or disconnect the circuit with the help of manual or automatic switches.

[0003] The existing distribution box has poor moisture resistance. The inside of the distribution box placed in the dark and humid environment underground is particularly prone to moisture, which can easily damage the electrical components in the distribution box, posing a great safety hazard and reducing the service life of the distribution box. At present, the most convenient dehumidification method is to place a desiccant or a drying plate to absorb the moisture in the distribution box to achieve the purpose of removing moisture, but this method has the following inconveniences in actual operation:

[0004] 1. When the desiccant or drying plate absorbs moisture to a certain extent, its moisture absorption function is reduced or lost, and the staff cannot replace it in time, resulting in excessive moisture in the distribution box, which poses a major safety hazard;

[0005] 2. The staff can only estimate the expiration time of the desiccant or drying plate based on the time it has been placed, and cannot accurately determine its adsorption capacity;

[0006] 3. At present, some desiccants and drying plates can be used multiple times. However, in actual operation, the desiccant or drying plate needs to be taken to a special drying place for treatment after the first use, which is very inconvenient and reduces the work efficiency of the staff. Some staff will directly replace the new desiccant or drying plate for convenience, which also increases the waste of resources.

A receiving plate 64 is fixedly arranged on the left side of the upper end of the chain 63. A groove (not shown in the figure) is arranged on the upper surface of the receiving plate 64 so that the drying and dehumidifying plate 5 in the dehumidification chamber 3 just falls into the groove, making the translation process more stable. The first rotating shaft 61 on the left side is connected to the first motor 65 through a coupling. The first motor 65 is electrically connected to the controller 101. The first motor 65 is a forward and reverse motor, which can move the receiving plate 64 to the right side of the chain 63 so that it is located at the lower left end of the third door panel 114, and can also return the chain 63 to the leftmost side so that it is located at the lower end of the second door panel 112.

[0060] Preferably, the right side of the third door panel 114 is rotatably connected to the right side of the delivery port 113;

[0061] The third door panel opening and closing component 7 includes a rack 71 hinged at the lower end of the third door panel 114, the lower end of the rack 71 is fixedly connected to the bottom wall of the lower cavity 13 by a spring 72, a first gear 73 is also provided on the first rotating shaft 61 on the right side, the first gear 73 is meshed with the rack 71, a limiting slider 74 is provided at the front side of the lower end of the rack 71, and the limiting slider 74 is slidably arranged in a limiting slide groove (not shown in the figure) on the front side wall of the lower cavity 13.

[0063] In this embodiment, the first motor 65 rotates forward to drive the chain 63 to move to the right, and at the same time, the first gear 73 drives the rack 71 to move downward, so that the third door panel 114 rotates downward and opens; at the same time, the rack 71 drives the second gear 81 to rotate, and the first winding drum 83 releases the line. When the receiving plate 64 moves to the lower side of the leftmost end of the conveying port 113, the first motor 65 stops working. At this time, the positive magnetic block 86 just drops to the leftmost end of the conveying port 113 and can just attract the negative magnetic block 51 at the top of the drying and hygroscopic plate 5; at this time, the first motor 65 reverses, and the first winding drum 83 first reels the line, lifts the positive magnetic block 86 and the drying and hygroscopic plate 5 adsorbed at its lower end into the drying chamber 4, and at the same time, the third door panel 114 is closed, and the receiving plate 64 returns to the leftmost side of the chain 63.

At the same time, the second winding drum 93 can be driven to reel in the line through the gear group, so that the first door panel 15 is gradually opened. After the first door panel 15 is fully opened, the sleeve 109 will also push the dried desiccant plate 5 to the through hole 111 in the dehumidification chamber 3. Then, the second motor 108 is reversed, so that the sleeve 109 gradually retracts to the far right and the first door panel 15 is finally closed.

[0076] The working principle of this device: the humidity sensor 16 installed in the distribution box transmits the monitored humidity signal to the controller 101, and the controller 101 compares the humidity signal with the preset threshold value. If the threshold value is exceeded, the controller 101 controls the air intake fan 2 to start, draws the outside air into the dehumidification chamber 3, and dries the air through the drying and hygroscopic plate 5, and then transmits it to the distribution box, so that the humidity in the distribution box meets the standard. After the drying and hygroscopic plate 5 has been used for a period of time, the weighing sensor 116 will monitor the weight signal of the drying and hygroscopic plate 5 and transmit it to the controller 101. The controller 101 compares the signal with the preset value. If the preset value is reached, the controller 101 controls the electric push rod 1151 to open the second door panel 112, so that the drying and hygroscopic plate 5 falls onto the translation component 6 in the lower cavity 13. At this time, the controller 101 controls the second motor 108 to start, and pushes the spare drying and hygroscopic plate 5 in the drying chamber 4 into the dehumidification chamber by opening the first door panel 15 and using the pushing component 10. 3, and then the controller 101 controls the second motor 108 to reverse, so that the first door panel 15 is closed and the pushing component 10 returns to its original position; at the same time or after a short interval, the controller 101 controls the first motor 65 to start, and uses the movement of the chain to drive the receiving plate 64 to move to the right, open the third door panel 114, and lower the positive magnetic block 86, so that the drying and moisture-absorbing plate 5 that falls on the receiving plate 64 is transported to the drying chamber 4 for drying, so as to prepare for the next replacement and use, and then the controller 101 controls the first motor 65 to reverse, so that all components return to their original positions.
