Description

Technical Field

[0001] The invention relates to the field of electric energy metering boxes, and in particular to a moisture-proof and dehumidifying 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) installed with electricity metering instruments, electricity energy collection, electrical protection and other related accessory equipment.

[0003] The installation environment of the electricity meter box can be divided into indoor and outdoor. The electricity meter box installed outdoors faces the problem of internal short circuit, tripping and even fire due to humidity in rainy and snowy weather. A fire will burn the cable lines and electricity meters in the meter box, posing a hidden danger to equipment and personal safety, and bringing 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 inlet and outlet holes of the electric energy meter box, setting rain shields for the electric energy meter box, and setting water absorbent parts in the box body.

[0005] However, when the electric energy meter box is in use, heat is generated when the accessory equipment is running, so there is a temperature difference between the inside and outside of the box, and 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 electric energy meter box with moisture-proof and dehumidification function cannot handle 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 condensed on the inner wall of the box. Summary of the invention

[0015] Preferably, a hollow rod for protecting the main wiring harness is vertically mounted on the base plate, and the back side of the portion of the hollow rod located above the base plate is fixedly connected to the front side of the mounting vertical plate.

[0016] Preferably, a door support rod for supporting the upper door is hingedly connected to the front of the hollow rod, and a door support rod bracket matching the door support rod is arranged on the inner side of the upper door.

[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 the condensed water condensed on the inner wall of the box.

[0018] First, when the external environment is relatively humid and the inside of the power meter box needs to be cooled, the first reversible fan can rotate to discharge the air inside the power meter box. At this time, the outside air will be sucked into the power meter box from the first air hole and the second air hole, and the moisture in the outside air will be absorbed by the dehumidification component to ensure that dry air enters the power 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, 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, 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 formed condensed water 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 even in 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 can work normally, the electric energy meter box can reduce the condensation of condensed water by absorbing moisture and reducing the temperature difference. When the dehumidification component absorbs full moisture, it can treat the formed condensed water by drying the inner wall of the box, reduce the temperature difference and dry the dehumidification component at the same time, finally achieving the purpose of reducing the condensed water condensed on the inner wall of the box. In addition, the ability of the box to be raised and lowered also facilitates maintenance personnel to conduct a comprehensive inspection of the inside of the electric energy meter box.

The cross section of the sleeve 607 is a triangular, quadrilateral, pentagonal, rounded triangle or rounded quadrilateral structure. The cross section of the top end of the output shaft of the first horizontal motor 606 is a pentagonal structure.

[0028] The working 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, and the wind is first sucked into the enclosure 104, and then sucked into the box 102 from the first air hole 1021, and then enters the inside of the box 2 through the second air hole 1011 on the base plate 101. In the process of entering the second air hole 1011 from the first air hole 1021, the wind will pass 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 adsorbed by the activated carbon block 402, so that the wind sent into the box 2 is always dry wind. After the wind enters the box 2, it moves from bottom to top and takes away the heat generated by the operation of the accessory equipment. First, it helps the accessory equipment to dissipate heat, and second, it helps to reduce the temperature difference when the temperature difference between the inside and outside of the box is large, and reduces the probability of condensed water condensing on the inside of the box. After taking away the heat, the wind continues to move upward, passes through the inside of the expanded annular guide 801, and then enters 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 the rotation direction is opposite to that of the third reversible fan 401 and the fourth reversible fan 403, and the wind that takes away the heat in the diversion housing 802 is sent out from the third air hole 8021, passes through the first air duct 501, passes through the ventilation slots on the ventilation plate 202, and reaches the outside through the gap between the ventilation plate 202 and the rain shield 106.

[0029] 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 wind can be blown out from the first wind 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-hole 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 can 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 condensation on the inner wall is minimized, and the condensation water that has been formed is blown at the same time to make it flow downward along the inner wall of the box body 2, and finally pass through the flow 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 will lose 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, and then reach the outside air from the first air hole 1021 after passing through the dehumidification component 4. In this process, the hot air will gradually dry the activated carbon block 402 until its water absorption function is restored.

[0030] When the electric energy meter box needs to be inspected, the second horizontal motor 707 is started after unlocking, and the second horizontal motor 707 drives the upper door to rotate and open, and the left protrusion 704 and the right protrusion 705 rotate with the upper door, driving the fourth bevel gear 706 to rotate, and 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 to rotate, and the third bevel gear 703 drives the left door and the right door to rotate and open through the left door shaft 701 and the right door shaft 702, respectively. After each door reaches the expected position, the door support rod can be rotated to clamp the end of the door support rod away from the upper door into the door support rod bracket. If the inspection is carried out on rainy days, the upper door can play a certain role in keeping out the rain. When closing the door, remove the door support rod to reverse the output shaft of the second horizontal motor 707.

[0031] 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 mounting vertical plate 103, then while all doors remain closed, hold the horizontal L-shaped lever and slide it upward in the bar-shaped hole on the enclosure 104, the horizontal L-shaped lever drives the claw 609 to move upward, the claw 609 drives the vertical rod to slide upward in the block 608, the reset spring is compressed by the pressure, the claw leaves the shaft sleeve 607, and no longer restricts the rotation of the horizontal shaft 604, the first horizontal motor 606 is started, and the first horizontal The horizontal motor 606 drives the horizontal shaft 604 to rotate, the horizontal shaft 604 drives the second bevel gear 605 to rotate, the second bevel gear 605 drives the first bevel gear 603 to rotate, the first bevel gear 603 drives the ball screw 601 to rotate, the screw nut moves upward on the ball screw 601, and drives the box 2 to move upward through the slider 602. After reaching the expected height, the first horizontal motor 606 is turned off, the horizontal L-shaped lever is released, and the reset spring gradually returns to the natural extension position, driving the claw 609 to re-clamp the sleeve 607. At this time, the various angles of the accessory equipment in the box 2 can be repaired, and the gradually expanding rain shielding ring 203 can play a good role in rain and sun protection at this time.

[0032] It should be noted that the present invention is not limited to the specific structures shown in the drawings in the above-mentioned embodiments, and various changes can be made thereto within the knowledge scope of ordinary technicians in this field.
