Description

Technical Field

[0001] The invention relates to the technical field of electric energy metering boxes, in particular to a multifunctional electric energy metering box. Background Art

[0002] An energy meter is a device used to measure and record electrical energy consumption, usually installed in residential homes, commercial buildings or industrial facilities. It monitors power input and output to ensure that users or consumer units pay for electricity according to actual usage.

[0003] For example, Chinese patent CN212622747U discloses an electric energy meter box with good sealing performance. In this scheme, a sealing ring is provided on the front of the meter box, and a sealing groove corresponding to the sealing ring is embedded on the box door. When closing the box door, the slide is slid, and then the door clamping bolt is rotated to make the box door slide toward the meter box, so that the sealing ring is stuck in the sealing groove on the back of the door to prevent water vapor from entering the meter box.

[0004] However, the door setting position in the above solution makes it easier for water to accumulate at the upper side of the sealing ring than at other positions. Long-term accumulation of water will cause corrosion of the sealing ring at this position, resulting in poor sealing performance. Summary of the invention

The "connection" and "coupling" mentioned in the present invention, unless otherwise specified, include direct and indirect connections (couplings). In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0045] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0046] Refer to the following Figure 1-Figure 10The present invention is to describe a multifunctional electric energy meter box, which includes a box body 100, various components are arranged inside the box body 100, a box door 110 is hinged on one side of the box body 100, and the box door 110 can rotate with the hinge position as the center of the circle so as to open or close the box body 100, and a sealing groove 120 is arranged on the end surface of the box body 100 and the box door 110 close to each other, and the sealing groove 120 is a rectangular frame groove, and the size is similar to that of the box body 100, and the first sealing ring 200 and the second sealing ring 300 are respectively arranged in the two sealing grooves 120. When the box door 110 is closed, The first sealing ring 200 and the second sealing ring 300 fit together to seal the box door 110 and the box body 100. However, as the first sealing ring 200 and the second sealing ring 300 are used for a long time and the box door 110 is always in a closed state, water and dust will inevitably accumulate on the upper ends of the first sealing ring 200 and the second sealing ring 300, resulting in corrosion of the upper ends of the first sealing ring 200 and the second sealing ring 300. As time goes by, the sealing performance of the upper ends of the first sealing ring 200 and the second sealing ring 300 will decrease, resulting in poor overall sealing effect of the box body 100 and the box door 110.

[0047] In the present invention, an adjusting component is provided on the box body 100. The adjusting component can push the first sealing ring 200 and the second sealing ring 300 to move in the sealing slide groove 120 when the box door 110 is opened, so that a part of the first sealing ring 200 and the second sealing ring 300 originally located at the upper end of the sealing slide groove 120 moves to the surroundings, so that the surrounding parts of the first sealing ring 200 and the second sealing ring 300 are located at the upper end of the sealing slide groove 120, thereby preventing a certain part of the first sealing ring 200 and the second sealing ring 300 from being always at the upper end of the sealing slide groove 120, thereby preventing a certain part of the first sealing ring 200 and the second sealing ring 300 from being always corroded, and can extend the service life of the first sealing ring 200 and the second sealing ring 300. When the box door 110 is closed, the adjusting component no longer pushes the first sealing ring 200 and the second sealing ring 300 to rotate in the sealing slide groove 120.

[0048] Specifically, the adjustment assembly in the embodiment of the present invention includes a first sliding support rod 210 and a second sliding support rod 310. Figure 2 , Figure 3 and Figure 4As shown, one end of the first sliding support rod 210 is hinged to the upper end of the box body 100 near the hinged position of the box body 100 and the door 110, and the other end of the first sliding support rod 210 is hinged with a first slider 220, the first slider 220 is slidably connected to the upper end of the door 110 away from the hinged position of the box body 100 and the door 110, and the first slider 220 slides in the horizontal direction toward the door 110; and one end of the second sliding support rod 310 is hinged to the lower end of the door 110 near the hinged position of the box body 100 and the door 110 The other end of the second sliding support rod 310 is hinged with a second slider 320, and the second slider 320 is slidably connected to the lower end of the box body 100 away from the hinged position of the box body 100 and the box door 110. When the box door 110 is opened, the first sliding support rod 210 rotates with the hinged position as the center of the circle, and the other end of the first sliding support rod 210 pulls the first slider 220 to slide on the box door 110. The first slider 220 is provided with an abutment plate 130, and the abutment plate 130 abuts on the second sealing ring 300, so that the first slider When the second sealing ring 200 slides, the second sealing ring 300 is pulled to move in the sealing slide groove 120, thereby changing the portion of the second sealing ring 300 at the upper end of the sealing slide groove 120; at the same time, the second sliding support rod 310 on the box door 110 pulls the second slider 320 located on the second sliding support rod 310 to slide on the box body 100, and the second slider 320 is also provided with an abutment plate 130, the abutment plate 130 abuts on the first sealing ring 200, and the second slider 320 pulls the first sealing ring 200 to move in the sealing slide groove 120 , thereby changing the portion of the first sealing ring 200 located at the upper end of the sealing slide groove 120. When the door 110 is ready to be closed, the abutment plates 130 on the first slider 220 and the second slider 320 are pulled outward, so that the two abutment plates 130 are respectively separated from the first sealing ring 200 and the second sealing ring 300. That is to say, during the closing process of the door 110, the first slider 220 and the second slider 320 will not push the first sealing ring 200 and the second sealing ring 300 to move in the sealing slide groove 120.

[0049] By setting the first sliding support rod 210 and the second sliding support rod 310, the first sealing ring 200 and the second sealing ring 300 are pushed to move in the sealing slide groove 120 by opening and closing the box door 110, thereby reducing the need for setting additional power sources and saving energy. It is understandable that since the multifunctional metering box needs to be inspected regularly, the box door 110 needs to be opened during the inspection to inspect the components inside the box body 100, so the positions of the first sealing ring 200 and the second sealing ring 300 can be adjusted during the process of opening and closing the box door 110 during regular inspections, thus killing two birds with one stone.

[0050] It should be noted that if Figure 3 and Figure 4As shown, in this embodiment, in order to ensure that the first slider 220 can slide horizontally at the upper end of the box door 110, a horizontally distributed first sliding groove 230 is opened at the upper end of the box door 110, and the first slider 220 is slidably connected in the first sliding groove 230 so that the first slider 220 slides horizontally at the upper end of the box door 110; at the same time, in order to ensure that the second slider 320 can slide horizontally at the lower end of the box body 100, a horizontally distributed second sliding groove 330 is opened at the lower end of the box body 100, and the second slider 320 is slidably connected in the second sliding groove 330 so that the second slider 320 slides horizontally at the lower end of the box body 100.

[0051] In a further embodiment, the sealing grooves 120 on the box body 100 and the door 110 are provided with a plurality of latches 140 distributed radially along the sealing grooves 120, such as Fig. 9 As shown, the first sealing ring 200 and the second sealing ring 300 are provided with teeth on the outer periphery of the inner part of the sealing groove 120, and the bayonet 140 just meshes with the teeth. The bayonet 140 is specifically close to the outer end of the sealing groove 120. The setting of the bayonet 140 can prevent the first sealing ring 200 and the second sealing ring 300 from detaching from the sealing groove 120, so that the first sealing ring 200 and the second sealing ring 300 can move in the sealing groove 120 under the pulling action of the first slider 220 and the second slider 320.

[0052] In a further embodiment, Fig. 9 As shown, an oil flow channel 450 is provided at a position close to the sealing groove 120 on the box body 100, and the oil flow channel 450 and the sealing groove 120 are of similar size, that is, the oil flow channel 450 and the sealing groove 120 can overlap in the projection direction, and a transmission gear 460 is rotatably arranged in the oil flow channel 450, and the transmission gear 460 is meshed with the teeth on the outer periphery of the first sealing ring 200. When the box door 110 is in a closed state, the box door 110 and the two sealing grooves 120 on the box body 100 are close to each other, and at the same time, the first sealing ring 200 and the second sealing ring 300 are fitted together, and the two form a similar cylindrical shape, as shown specifically in FIG. Fig. 9As shown, when the transmission gear 460 rotates, the transmission gear 460 drives the first sealing ring 200 and the second sealing ring 300 to rotate 180° in the two sealing grooves 120, and can push the bayonet pin 140 to shorten radially, so that the bayonet pin 140 does not restrict the rotation of the first sealing ring 200 and the second sealing ring 300. It should be noted that the bayonet pin 140 elastically expands and contracts radially in the sealing groove 120, that is, there is a spring inside the bayonet pin 140 (not shown in the figure). When the bayonet pin 140 is subjected to the force of the first sealing ring 200 rotating, the teeth on the outer periphery of the first sealing ring 200 and the teeth on the outer periphery of the second sealing ring 300 push the bayonet pin 140 to shorten. When the transmission gear 460 stops rotating, the bayonet pin 140 is reset along the radial extension of the sealing groove 120 under the action of the spring, thereby re-restricting the first sealing ring 200 and the second sealing ring 300 from leaving the sealing groove 120.

[0053] It should be noted that by setting the transmission gear 460 to drive the first sealing ring 200 and the second sealing ring 300 to rotate 180°, the first sealing ring 200 and the second sealing ring 300 can be exchanged, so that the parts originally located at the outer periphery of the first sealing ring 200 and the second sealing ring 300 are rotated to the inside, and the parts originally located at the inner periphery of the first sealing ring 200 and the second sealing ring 300 are rotated to the outside, that is, Fig. 9 As shown, after the first sealing ring 200 and the second sealing ring 300 rotate 180°, the part originally located on the left side now rotates to the right side, and the part originally located on the right side now rotates to the left side. The first sealing ring 200 and the second sealing ring 300 can be driven to rotate 180° regularly by driving the transmission gear 460, so as to realize the function of regularly exchanging the inner and outer parts of the first sealing ring 200 and the second sealing ring 300, and further improve the service life of the first sealing ring 200 and the second sealing ring 300.

[0054] Specifically, a driving assembly is provided in the oil flow channel 450, and the driving assembly can drive the transmission gear 460 to rotate so that the transmission gear 460 drives the first sealing ring 200 and the second sealing ring 300 to rotate. The driving assembly includes a hydraulic motor 470 and an oil circulation pipe. The hydraulic motor 470 is provided in the oil flow channel 450, and the rotating shaft of the hydraulic motor 470 is meshed with the transmission gear 460. When the hydraulic motor 470 rotates, the transmission gear 460 can be driven to rotate. Both ends of the oil circulation pipe are connected to the oil flow channel 450 and the two ends of the oil circulation pipe are connected to the oil flow channel 450. The oil circulation pipe can make the oil in the oil flow channel 450 circulate. In order to make the oil in the oil flow channel 450 flow, an extrusion cylinder and an oil storage tank 440 are connected to the oil circulation pipe. The oil circulation pipe includes a first oil pipe 420 and a second oil pipe 430. Figure 6As shown, one end of the first oil pipe 420 is connected to the lower end of the extrusion cylinder, and the other end of the first oil pipe 420 is connected to one end of the oil flow channel 450, the second oil pipe 430 is connected to the oil storage tank 440, and the other end of the second oil pipe 430 is connected to the other end of the oil flow channel 450. A partition (not shown in the figure) is provided in the portion of the oil flow channel 450 connecting the first oil pipe 420 and the second oil pipe 430. The partition allows the oil squeezed out of the extrusion cylinder to enter the oil flow channel 450 through the first oil pipe 420, and the oil in the oil flow channel 450 enters the storage tank through the second oil pipe 430. If the partition is not provided, the oil squeezed out from the first oil pipe 420 will enter the second oil pipe 430 through the portion between the positions close to each other on the oil flow channel 450 where the first oil pipe 420 and the second oil pipe 430 are connected, thereby preventing the oil in other parts of the oil flow channel 450 from flowing.

[0055] It should be noted that the working principle of the hydraulic motor 470 is opposite to that of the hydraulic gear pump, that is, the principle of the hydraulic pump is to make the oil flow by driving two meshing gears to rotate, while the hydraulic motor 470 uses the oil flow in the oil flow channel 450 to drive the gear to rotate, so that the hydraulic motor 470 drives the transmission gear 460 to rotate. The extrusion cylinder in this embodiment includes a rotating rod 400 and an extrusion cylinder body 410. The extrusion cylinder body 410 is fixedly arranged on the box body 100. The rotating rod 400 is spirally connected to the extrusion cylinder body 410. The first oil pipe 420 is connected to the lower end of the extrusion cylinder body 410. The rotating rod 400 and the extrusion cylinder body 410 are filled with oil. By driving the rotating rod 400 to rotate, the rotating rod 400 can be made to move relative axially in the extrusion cylinder body 410, that is, move up and down. When the rotating rod 400 moves downward, it pushes the oil in the extrusion cylinder body 410 into the oil flow channel 450, thereby making the oil in the oil flow channel 450 flow.

[0056] When the rotating rod 400 is set to rotate from the initial state to the point where the rotating rod 400 abuts against the lower end of the extrusion cylinder 410, the oil flows to drive the transmission gear 460, and the transmission gear 460 drives the first sealing ring 200 and the second sealing ring 300 to rotate 180° in the two sealing grooves 120. When the rotating rod 400 abuts against the lower end of the extrusion cylinder 410 to the initial state, the oil flows in the reverse direction to drive the transmission gear 460 to rotate in the reverse direction, and the transmission gear 460 can also drive the first sealing ring 200 and the second sealing ring 300 to rotate 180° in the second sealing groove 120. Operators can be regularly dispatched to rotate the rotating rod 400, and each time the rotating rod 400 is rotated, the rotating rod 400 is rotated to the lower end of the extrusion cylinder 410 or the initial state, ensuring that the first sealing ring 200 and the second sealing ring 300 rotate 180° in the two sealing grooves 120 to exchange the inner and outer parts.

[0057] In a further embodiment, the first sealing ring 200 and the second sealing ring 300 have a foldable sealing pad 500 at one end that is close to each other when the door 110 and the box body 100 are closed. Fig. 9 As shown, the cross section of the sealing gasket 500 is fan-shaped, and the state when the first sealing ring 200 and the second sealing ring 300 are not attached is as shown in FIG. Fig. 9 As shown, the first sealing ring 200 and the second sealing ring 300 both have two sealing pads 500 with fan-shaped cross sections. The two fan-shaped edges of the sealing pad 500 are relatively hard and the middle is elastic, so that when the first sealing ring 200 and the second sealing ring 300 are not attached, the fan-shaped edges of the two sealing pads 500 are attached to each other; and the state when the first sealing ring 200 and the second sealing ring 300 are attached to each other is as shown in FIG. Fig. 9 As shown, the two sealing gaskets 500 on the first sealing ring 200 and the second sealing ring 300 are compressed and flattened, so that the fan-shaped edges of the two sealing gaskets 500 are unfolded. Such a structural setting can shield the surfaces of the first sealing ring 200 and the second sealing ring 300 exposed to the outside when the box body 100 and the box door 110 are opened, thereby preventing the outside world from causing dust and other impurities to adhere to the surface due to long-term contact with the air, resulting in the box body 100 and the box door 110 not being sealed tightly when closed. The two fan-shaped sealing gaskets 500 can better shield the surfaces of the first sealing ring 200 and the second sealing ring 300 when the box body 100 and the box door 110 are opened, and the first sealing ring 200 and the second sealing ring 300 can fit tightly together when the box body 100 and the box door 110 are closed, thereby achieving a better sealing effect.

[0058] It should be noted that the material in the middle of the sealing gasket 500 is elastic rubber, and the fan-shaped edges are hard materials, such as plastic. The middle position where the two rubber fan-shaped edges are connected to each other can be bent, so that the two sealing gaskets 500 can be folded together and fit together to prevent the surfaces of the first sealing ring 200 and the second sealing ring from being exposed when the box body 100 and the door 110 are opened.

[0059] In a further embodiment, a viewing window 150 is provided on the box door 110 , and glass is installed on the viewing window 150 , so that the operator can observe the situation inside the box body 100 through the viewing window 150 before opening the box door 110 .

[0060] In a further embodiment, ventilation holes 160 are provided on the side walls of the box body 100 to facilitate heat dissipation.

[0061] The specific working process of a multifunctional electric energy meter box provided by the present invention is described in combination with the above embodiments:

[0062] When inspecting various components inside the box 100, the operator opens the box door 110, and the fan-shaped edges of the two sealing gaskets 500 on the first sealing ring 200 and the second sealing ring 300 are folded together to cover the surfaces of the first sealing ring 200 and the second sealing ring 300 that are close to each other to prevent the surfaces from contacting with the air. The specific state is as follows: Fig.10 shown.

[0063] During the opening process of the box door 110, when the box door 110 is opened to a small extent, the operator makes the abutment plate 130 on the first slider 220 and the second slider 320 abut against the first sealing ring 200 and the second sealing ring 300, and then continues to open the box door 110. The first sliding support rod 210 and the second sliding support rod 310 on the box door 110 and the box body 100 respectively pull the first slider 220 and the second slider 320 to slide in the first sliding groove 230 and the second sliding groove 330. The first slider 220 and the second slider 320 can pull the first sealing ring 200 and the second sealing ring 300 to move in the sealing groove 120 through the abutment plate 130, thereby changing the positions of the first sealing ring 200 and the second sealing ring 300 in the sealing groove 120.

[0064] After the inspection of various components inside the box body 100 is completed, the operator forcibly pulls the abutment plate 130 on the first slider 220 and the second slider 320 outward a certain distance so that the abutment plate 130 can be separated from the first sealing ring 200 and the second sealing ring 300 to prevent the first sliding support rod 210 and the second sliding support rod 310 from pushing the first sealing ring 200 and the second sealing ring 300 to reset again during the closing process of the box door 110 through the abutment plate 130 on the first slider 220 and the second slider 320. After the box door 110 is closed, the two sealing gaskets 500 on the surfaces of the first sealing ring 200 and the second sealing ring 300 on the box door 110 and the box body 100 that are close to each other are unfolded and flattened so that the box door 110 and the box body 100 can be sealed. The specific state is as follows: Fig. 9 shown.

[0065] After the box door 110 is closed, the operator twists the rotating rod 400, and the rotating rod 400 rotates in the extrusion cylinder 410 so as to gradually abut against the lower end of the extrusion cylinder 410, so that the oil in the extrusion cylinder 410 can enter the oil flow channel 450 through the first oil pipe 420, and the oil flows in the oil flow channel 450 and flows into the oil storage tank 440 from the second oil pipe 430. When the oil flows in the oil flow channel 450, it can drive the hydraulic motor 470 to rotate. The rotating shaft of the hydraulic motor 470 is engaged with the transmission gear 460, and the transmission gear 460 drives the first sealing ring 200 and the second sealing ring 300 located on the inner surface of the sealing slide groove 120 to rotate 180° to exchange the inner and outer parts of the first sealing ring 200 and the second sealing ring 300, so that the outer parts of the first sealing ring 200 and the second sealing ring 300 are used for a period of time and then replaced by rotating 180° to the inside of the first sealing ring 200 and the second sealing ring 300, so that the inner part is rotated to the outside.

[0066] The time interval for inspecting the box body 100 can be set to be the same as the time interval for twisting the rotating rod 400. After opening the box door 110 to inspect the box body 100, the inner and outer parts of the first sealing ring 200 and the second sealing ring 300 can be adjusted by twisting the rotating rod 400.

[0067] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
