Description

Technical Field

[0001] The present application relates to the technical field of electric energy meter boxes, and in particular to an electric energy meter box. Background Art

[0002] The electric energy meter box is a device for measuring electric energy, usually including an electric energy meter, voltage and current transformers for measurement and their secondary circuits, electric energy metering panels, cabinets, boxes and other auxiliary equipment. Depending on the usage scenario, the electric energy meter box can be suitable for both outdoor and indoor scenarios.

[0003] In the related art, the electric energy meter box includes a box body and a box door, the box door is rotatably connected to the box body, a receiving groove is opened in the box body, a dehumidification bag is arranged in the receiving groove, and the dehumidification bag can perform dehumidification processing.

[0004] In some humid environments, if the staff opens the door for maintenance for a long time, since the dehumidification bag is placed directly in the receiving slot, the dehumidification bag will dehumidify the outside air, which reduces the service life of the dehumidification bag. Summary of the invention

[0005] In order to improve the problem that the dehumidification bag needs to be replaced frequently, the present application provides an electric energy metering box.

[0006] The present application provides an electric energy meter box, which adopts the following technical solution: An electric energy meter box comprises a box body and a box door, wherein the box door is rotatably connected to the box body, the box body is provided with a receiving groove, a placement groove is provided in the receiving groove, a dehumidification bag is provided in the placement groove, and a placement plate for sealing the placement groove is slidably connected to the placement groove.

[0007] By adopting the above technical solution, the dehumidification bag is located in the placement slot. Since the placement plate is slidably connected to the placement slot, the placement plate can seal the placement slot. The staff can choose whether to let the dehumidification bag dehumidify the receiving slot. When the box door is opened for a long time, the dehumidification bag can reduce the effect of adsorbing external moisture.

[0008] Optionally, a receiving groove is provided on the box body, a movable hole connected to the receiving groove is provided on the box body, a movable rope is provided in the movable hole, a floating block for floating on the water surface is provided in the receiving groove, the movable rope connects the placement plate and the floating block, and the gravity of the floating block is greater than the gravity of the placement plate; when rainwater accumulates in the receiving groove, the placement plate does not block the placement groove.

[0009] By adopting the above technical scheme, when rainwater accumulates in the receiving tank, the floating block floats on the water surface in the receiving tank, and the floating block drives the placement plate to move through the moving rope, so that the placement plate does not block the placement tank, so that the dehumidification bag can dehumidify the receiving tank on rainy days, reducing the possibility of damage to the electrical components inside the box due to excessive humidity in rainy days; in rainy weather, the dehumidification bag can reduce the moisture in the receiving tank, so that the receiving tank is not prone to excessive humidity, so as to ensure the normal use of the electrical components in the box; because the gravity of the floating block is greater than the gravity of the placement plate, when there is no rainwater in the receiving tank, the dehumidification bag can fix the placement plate through the moving rope, so that the placement plate can stably block the placement tank.

[0010] Optionally, a through hole connected to the accommodating groove is provided on the box body, the cross-sectional area of ​​the through hole is smaller than the cross-sectional area of ​​the accommodating groove, and the through hole is used for rainwater to be discharged from the accommodating groove.

[0011] By adopting the above technical solution, the cross-sectional area of ​​the perforation is smaller than the cross-sectional area of ​​the receiving groove, and rainwater can be discharged from the receiving groove from the perforation. The speed at which rainwater enters the receiving groove needs to be greater than the speed at which rainwater is discharged from the perforation in order to accumulate rainwater in the receiving groove. In the case of long-term light rain, the problem of water accumulation in the receiving groove is reduced, thereby avoiding the situation where the placement plate is opened in light rain, causing the dehumidification bag to dehumidify the receiving groove.

[0012] Optionally, a limit plate is slidably connected to the box body, and the limit plate is used to block the opening of the accommodating groove.

[0013] By adopting the above technical solution, in the case of heavy rain, the opening of the storage tank is blocked by the limiting plate, and the staff can close the opening of the storage tank in time, and move the placement plate to allow the dehumidification bag to always dehumidify the storage tank, reducing the possibility of heavy rain entering the storage tank through the moving hole, and further improving the safety performance inside the box.

[0014] Optionally, a first magnet is provided on the moving rope, and a second magnet is provided on the limiting plate. When rainwater accumulates at the moving hole, the first magnet attracts the second magnet, and the limiting plate blocks the opening of the accommodating groove.

[0015] By adopting the above technical solution, when rainwater accumulates at the moving hole, the floating block drives the moving rope to move. Since the first magnet is arranged on the moving rope, the first magnet absorbs the second magnet, allowing the limiting plate to slide on the box body, so that the limiting plate can block the containing groove, thereby reducing the possibility of rainwater entering the containing groove from the moving hole and improving the safety performance of the box body.

[0016] Optionally, a fixing groove is opened in the accommodating groove, a fixing spring is arranged in the fixing groove, a fixing plate is arranged on the fixing spring, the fixing spring drives the fixing plate to protrude from the fixing groove, and the placement plate is located on the protruding path of the fixing plate; when the fixing plate is located on the moving path of the placement plate, the placement plate does not block the placement groove.

[0017] By adopting the above technical solution, the fixing plate is driven to protrude from the fixing slot by the fixing spring, and the placement plate is located on the protruding path of the fixing plate. When the placement plate does not block the placement slot, the fixing plate is driven by the fixing spring to protrude from the fixing slot, so that the fixing plate restricts the placement plate, thereby preventing the placement plate from blocking the placement slot, so that the dehumidification bag can perform dehumidification treatment in the receiving slot for a long time, thereby increasing the dehumidification stability of the dehumidification bag in rainy days.

[0018] Optionally, an operating hole connected to the accommodating slot is provided on the box body, an operating strip is slidably connected in the operating hole, an operating slope is provided on the operating strip, the distance between the operating slope and the bottom wall of the fixed slot gradually decreases along the direction from the accommodating slot to the operating hole, and the operating slope is located on the sliding path of the fixed plate.

[0019] By adopting the above technical solution, the distance between the operating slope and the bottom wall of the fixed groove is gradually reduced along the direction from the accommodating groove to the operating hole, and the operating slope is located on the sliding path of the fixed plate. The staff presses the operating bar to allow the operating bar to drive the fixed plate to move in the direction of the fixed groove, so that the fixed plate can be retracted into the fixed groove, allowing the placement plate to block the placement groove, so that the staff can quickly achieve the blocking of the placement groove by the placement plate, thereby eliminating the need for the staff to open the box door again to pull the placement plate, reducing the staff's operating steps.

[0020] Optionally, the placement groove penetrates to the side of the box body, and a stop plate is rotatably connected to the placement groove, and the stop plate blocks the side through which the placement groove penetrates.

[0021] By adopting the above technical solution, the stop plate is rotatably connected to the placement slot, and the stop plate blocks one side of the placement slot, so that the staff can open the stop plate to replace the dehumidification bag in the placement slot, allowing the staff to replace the dehumidification bag without opening the box door, further reducing the difficulty of replacing the dehumidification bag.

[0022] Optionally, a stop strip is provided on the stop plate, a fixing strip is provided on the fixing plate, and a fixing hole is provided on the stop strip for inserting the fixing strip; when the fixing plate is located in the fixing groove, the fixing strip is located in the fixing hole, and at this time the stop plate blocks one side through which the placement groove passes; when the fixing plate protrudes out of the fixing groove, the fixing strip is separated from the fixing hole.

[0023] By adopting the above technical solution, when the fixing plate is located in the fixing groove, the fixing strip is located in the fixing hole, and the fixing strip restricts the stop strip so that the stop strip cannot move, thereby fixing the stop plate on the box body and preventing people from forcibly turning the stop plate; when the fixing plate protrudes from the fixing groove, the fixing strip disengages from the fixing hole, so that the fixing strip does not restrict the stop strip, thereby allowing the stop plate to rotate on the box body, so that the stop plate can rotate stably.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. The dehumidification bag is placed in the placement slot. Since the placement plate is slidably connected to the placement slot, the placement plate can seal the placement slot. The staff can choose whether to let the dehumidification bag dehumidify the storage slot. When the box door is opened for a long time, the dehumidification bag can reduce the effect of adsorbing external moisture.

[0025] 2. The fixing plate is driven to protrude from the fixing slot by a fixing spring, and the placement plate is located on the protruding path of the fixing plate. When the placement plate does not block the placement slot, the fixing plate is driven by the fixing spring to protrude from the fixing slot, so that the fixing plate restricts the placement plate, thereby preventing the placement plate from blocking the placement slot, so that the dehumidification bag can perform dehumidification treatment in the receiving slot for a long time, thereby increasing the dehumidification stability of the dehumidification bag in rainy days.

A first fixing rod 331 is fixedly connected to the groove wall of the accommodating groove 3, and a second fixing rod 332 is fixedly connected to the placement groove 2. The moving rope 33 passes over the first fixing rod 331 and the second fixing rod 332 in turn, and the moving rope 33 can slide on the first fixing rod 331 and the second fixing rod 332. When the floating block 32 abuts against the bottom wall of the accommodating groove 3, the placement plate 22 completely blocks the placement groove 2. When the floating block 32 floats up, the placement plate 22 can not block the placement groove 2.

[0033] Reference Figure 2 When rainwater accumulates in the receiving tank 3, the floating block 32 can float up, and the floating block 32 drives the placement plate 22 to move downward through the moving rope 33, so that the placement plate 22 does not block the placement tank 2, allowing the dehumidification bag 21 to dehumidify the receiving tank 12, reducing the situation where rain outside increases the humidity in the receiving tank 12.
