Description
Technical Field
[0001] The invention relates to the field of electric energy metering boxes, and in particular to a moisture-proof and dehumidification electric energy metering box for outdoor use. Background Art
[0002] The electricity meter box is a device that measures the electricity sold by the power supply department, that is, how much electricity the user uses. The electricity meter box includes a box (also called a meter box) that is equipped with electricity metering instruments, electricity energy collection, electrical protection and other related accessory equipment.
[0003] The installation environment of electricity meter boxes can be divided into indoor and outdoor. Electricity meter boxes installed outdoors are prone to internal short circuits due to humidity in rainy and snowy weather, causing tripping and even fire. Fire will burn the cable lines and electricity meters in the meter box, posing hidden dangers to equipment and personal safety, and adding pressure to maintenance work.
[0004] Therefore, an electric energy meter box with moisture-proof and dehumidification function came into being. The existing electric energy meter box with moisture-proof and dehumidification function mainly achieves moisture-proof and dehumidification by adding seals to the wire inlet and outlet holes of the electric energy meter box, setting rain shields for the electric energy meter box, and setting water-absorbing parts in the box body.
[0005] However, during the use of the electricity meter box, there is a temperature difference between the inside and outside of the box because the accessory equipment generates heat when running. The water absorption capacity of the water absorbent is also limited. Therefore, the moisture in the box will condense into condensed water on the inner wall of the box. For this condensed water, the existing electricity meter box with moisture-proof and dehumidification function is still unable to deal with the condensed water on the inner wall of the box.
[0006] Therefore, the existing electric energy metering box with moisture-proof and dehumidification function has the problem of a large amount of condensed water condensing on the inner wall of the box. Summary of the Invention

[0017] The beneficial effects of the present invention are as follows: the moisture-proof and dehumidification electric energy metering box for outdoor use provided by the present invention can reduce condensed water condensed on the inner wall of the box.
[0018] First, when the external environment is relatively humid and the inside of the electricity meter box needs to be cooled, the first reversible fan can be rotated to discharge the air inside the electricity meter box. At this time, the outside air will be sucked into the inside of the electricity meter box from the first air hole and the second air hole. The moisture in the outside air will be adsorbed by the dehumidification component to ensure that dry air enters the electricity meter box. The dry air can take away the heat generated by the operation of the accessory equipment and be discharged to the outside through the third air hole, thereby reducing the temperature difference between the inside and outside of the box and making it difficult for condensed water to condense.
[0019] Secondly, when the dehumidification component is full of water, the humidity sensor in the box senses that the humidity has reached the critical value, and the first reversible fan stops rotating, and the second reversible fan starts rotating to draw in external air. The external air is heated by the heating element and enters the second air duct, and then passes through the gap between the side wall of the multi-hole plate and the inner wall of the square frame to reach the surface of the flared annular guide member, and is guided by the flared annular guide member to be blown to the inner wall of the box. While drying the condensed water formed on the inner wall of the box, it can also blow the condensed water formed on the inner wall of the box downward and flow out from the outflow port on the base plate. At the same time, the hot air can also increase the temperature of the box, thereby reducing the temperature difference, so that the condensed water is not easy to condense under relatively humid conditions. At the same time, a part of the hot air will reach the outside through the second and third air holes. In this process, the activated carbon blocks in the dehumidification component will be dried, and they can play a dehumidifying role again after drying.
[0020] Therefore, when the dehumidification component is functioning properly, the energy meter box can reduce condensation by absorbing moisture and reducing temperature differences. When the dehumidification component is fully absorbed, the box's inner walls can be dried to remove any condensation, reducing the temperature difference and drying the dehumidification component simultaneously, ultimately reducing condensation on the box's inner walls. Furthermore, the box's ability to be raised and lowered facilitates comprehensive inspection of the interior of the energy meter box by maintenance personnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 13 、 Figure 14 、 Figure 15 、 Figure 16As shown, a ball screw 601 is installed vertically and rotatably between the base plate 101 and the dual-path air flow plate 3. The ball screw 601 is located on the left side of the base plate 101. The bottom of the ball screw 601 passes through the base plate 101. A screw nut matching the ball screw 601 is installed on the ball screw 601. A slider 602 is fixedly installed outside the screw nut. The slider 602 is fixedly connected to the left side of the inner wall of the box body 2. The slider 602 is also fixedly installed on the right side of the inner wall of the box body 2. A sliding rod is installed between the base plate 101 and the dual-path air flow plate 3 for the slider 602 on the right side to slide up and down. The bottom of the ball screw 601 is fixedly sleeved with a first bevel gear 603; a fence 104 is fixedly installed under the base plate 101, and a horizontal rotating shaft 604 is vertically installed on the fence 104. A second bevel gear 605 meshing with the first bevel gear 603 is fixedly sleeved on one end of the horizontal rotating shaft 604 close to the first bevel gear 603, and a first horizontal motor 606 for driving the horizontal rotating shaft 604 to rotate is fixedly installed on the fence 104.

The top of the return spring is fixedly connected to the bottom of the block 608, and the bottom of the return spring is fixedly connected to the top of the claw 609. When the claw 609 engages with the sleeve 607, the return spring is in a naturally extended state. A horizontal L-shaped lever is fixedly mounted on the side of the claw 609 near the enclosure 104. The enclosure 104 has a strip hole for the horizontal L-shaped lever to slide up and down. The cross-section of the sleeve 607 can be triangular, quadrilateral, pentagonal, rounded triangle, or rounded quadrilateral. The cross section of the top end of the output shaft of the first horizontal motor 606 is a pentagonal structure.
[0059] The operating principle of the present invention is as follows: The two third reversible fans 401 and the two fourth reversible fans 403 in the box 102 rotate, first drawing air into the enclosure 104, then into the box 102 through the first air hole 1021, and finally into the interior of the housing 2 through the second air hole 1011 on the base plate 101. As the air passes from the first air hole 1021 into the second air hole 1011, it passes through the third reversible fan 401, the activated carbon block 402, and the fourth reversible fan 403 in sequence. If it is rainy or the surrounding air is humid, the moisture in the humid air will be absorbed by the activated carbon block 402, ensuring that the air entering the housing 2 is always dry. After entering the housing 2, the air moves from bottom to top, carrying away heat generated by the operating accessories. This not only helps dissipate heat from the accessories, but also helps reduce the temperature difference between the inside and outside of the housing when there is a large temperature difference, reducing the probability of condensation on the inside of the housing. After removing the heat, the wind continues upward, passing through the interior of the flared annular guide 801, and then entering the diversion housing 802 through the multi-hole plate 303. While the two third reversible fans 401 and the two fourth reversible fans 403 are rotating, the first reversible fan 502 in the first air duct 501 is also rotating, but in the opposite direction of the third and fourth reversible fans 401 and 403. The wind that has removed the heat from the diversion housing 802 is sent out through the third air holes 8021, passes through the first air duct 501, and then passes through the ventilation slots on the ventilation plate 202, reaching the outside through the gap between the ventilation plate 202 and the rain shield 106.
[0060] The activated carbon block 402 in the dehumidification component 4 continuously absorbs water until it can no longer absorb water, and humid air will enter the box 102. At this time, the humidity in the box 102 rises, and the humidity sensor will sense it. When the humidity reaches the critical value, it means that the dehumidification component 4 can no longer work normally, and the rotation direction of the two third reversible fans 401 and the two fourth reversible fans 403 is changed, so that the wind can be blown out from the first air hole 1021, and the second reversible fan 505 in the second air duct 503 is started. The rotation direction of the second reversible fan 505 is opposite to that of the two third reversible fans 401 and the two fourth reversible fans 403, so that the outside air can pass through the ventilation plate 202 and be sucked into the box body 2. Before entering the second air duct 503, the air will first be heated by the heating element 504 and become relatively dry. Then the hot air will pass through the gap between the side wall of the multi-porous plate 303 of the dual-path air plate 3 and the inner wall of the square frame 301 to reach the outer surface of the flared annular guide 801. The shape of the flared annular guide 801 will guide the hot air to a position close to the inner wall of the box body 2, so that the hot air will flow downward along the inner wall of the box body 2 as much as possible, thereby increasing the temperature of the box body 2. By reducing the temperature difference, the inner wall will not condense into condensed water as much as possible. At the same time, the condensed water that has been formed will be blown to flow downward along the inner wall of the box body 2, and finally pass through the outflow outlet 1012 reserved on the base plate 101 and fall to the outside of the box body 2. At the same time, a part of the hot air loses the guidance of the guide plate during the process of gradually moving downward, and will enter the box 102 from the second air hole 1011, pass through the dehumidification component 4, and then reach the outside air from the first air hole 1021. In this process, the hot air will gradually dry the activated carbon block 402 until its water absorption function is restored.
[0061] When the energy meter box needs to be repaired, the lock is unlocked and the second horizontal motor 707 is started. The second horizontal motor 707 drives the upper door to rotate and open. The left and right protrusions 704 and 705 rotate with the upper door, driving the fourth bevel gear 706 to rotate. The fourth bevel gear 706 drives the third bevel gear 703 at the top of the left door shaft 701 and the right door shaft 702, respectively. The third bevel gear 703 drives the left door and the right door shaft 701 and 702 to rotate and open respectively. After each door reaches the expected position, the door strut is rotated to snap the end of the door strut away from the upper door into the door strut bracket. If repairs are required on rainy days, the upper door can provide a certain degree of rain protection. To close the door, the door strut is removed and the output shaft of the second horizontal motor 707 is reversed.
[0062] If it is necessary to inspect not only the accessory equipment on the front side of the electric energy meter box but also the back side of the vertical plate 103, then when all doors are closed, hold the horizontal L-shaped lever and slide it upward in the bar hole on the enclosure 104. The horizontal L-shaped lever drives the claw 609 to move upward, and the claw 609 drives the vertical rod to slide upward in the block 608. The reset spring is compressed by the pressure, and the claw leaves the shaft sleeve 607, no longer restricting the rotation of the horizontal shaft 604, and the first horizontal motor 606 is started. The horizontal motor 606 drives the horizontal shaft 604 to rotate, which in turn drives the second bevel gear 605 to rotate. The second bevel gear 605 drives the first bevel gear 603 to rotate, and the first bevel gear 603 drives the ball screw 601 to rotate. The ball screw nut moves upward on the ball screw 601, driving the box 2 upward via the slider 602.
