Description

Technical Field

[0001] The present invention relates to the technical field of electric meter boxes, in particular to a multifunctional electric meter box used outdoors. Background Art

[0002] As a crucial protective device for energy metering, meter boxes are widely used in residential, commercial, and industrial applications. Their core function is to provide safety protection for power equipment such as meters and instrument transformers, while also facilitating centralized meter management and data collection. Conventional outdoor meter boxes are susceptible to external influences, resulting in high temperatures and humidity inside, impacting the operation and service life of meters and instrument transformers.

[0003] In response to this, Chinese invention patent publication number CN117080890A provides a moisture-proof and dust-proof electric meter for outdoor use, comprising an electric meter housing and multiple electric meter bodies installed within the housing. A partition is horizontally provided within the housing, dividing the housing into two upper and lower chambers. The multiple electric meter bodies are located directly above the partition. A water collection tank is provided within the housing, located directly below the partition. A filling pipe is provided on the side wall of the housing, the liquid outlet of the filling pipe is connected to the top of the water collection tank, and the liquid inlet of the filling pipe is located outside the housing. A solenoid valve is provided on the filling pipe. The interior of the meter is cooled and dehumidified by a heat pipe, while the condensed water generated by dehumidification and the liquid added externally clean the air and remove dust. This achieves cooling and dehumidification.

[0004] However, the applicant has found that the prior art has at least the following problems:

[0005] Electricity meter boxes used near large construction sites will be subject to vibration caused by the operation of large equipment. If the vibration amplitude is too large, on the one hand, it may affect the operation of the internal equipment of the electricity meter box, and on the other hand, it will accelerate the evaporation of water inside the water collection tank, thereby causing the dehumidification work inside the electricity meter box to be triggered frequently.

DETAILED DESCRIPTION

[0030] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.

[0031] It should be noted that, unless otherwise defined, the technical or scientific terms used in the present invention should have the usual meanings understood by people with ordinary skills in the field to which the present invention belongs. The "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0032] like Figures 1 to 9 As shown, a specific embodiment of the present invention provides a multifunctional outdoor electric meter box, including a box body 101, a main chamber 301 for accommodating an electric meter 302 is provided inside the box body 101, a water collecting tank 501 for storing water is provided below the main chamber 301, a humidity sensor and a temperature sensor are installed inside the main chamber 301, and a plurality of heat exchange tubes 402 are provided above the main chamber 301. After the air in the main chamber 301 enters the water collecting tank 501 for washing, it is introduced into the heat exchange tube 402 for cooling and condensation, and the condensed water flows back to the water collecting tank 501, and the cooled air circulates back to the main chamber 301.

[0033] A floating plate 505 is installed in the water collecting tank 501, and the floating plate 505 is movably connected to a rocker arm 604 up and down. The top ball joint of the rocker arm 604 is connected to the bottom plate 303 of the main chamber 301, and a monitoring box 601 is installed on the bottom plate 303. A movable cavity 608 is opened in the monitoring box 601, and a guide groove 609 is opened on the side of the movable cavity 608. A counterweight block 610 is adapted to be installed in the guide groove 609. The counterweight block 610 and the floating plate 505 are vertically suspended by a connecting rope 607. The middle part of the connecting rope 607 is supported by a support to form a central support double vertical pull rope connection structure. A rangefinder for monitoring the displacement of the counterweight block 610 is installed in the movable cavity 608. The rangefinder is electrically connected to a controller, and the controller is electrically connected to a vibration reduction component. When the displacement of the counterweight block 610 exceeds the threshold displacement, the vibration reduction component adjusts the vibration reduction intensity.

[0034] During daily operation, when the humidity sensor and temperature sensor in the main chamber 301 detect that the temperature or humidity exceeds the threshold, the hot and humid air inside the main chamber 301 is introduced into the water collecting tank 501, and the air in the main chamber 301 is cleaned and slightly cooled. The air that has been cleaned flows to the heat exchange tube 402 above the main chamber 301 and is cooled, and the water vapor in the air is condensed, and the condensed water flows back to the water collecting tank 501. The cooled air circulates back to the main chamber 301, thereby achieving cooling, dust removal and dehumidification of the main chamber 301.

[0035] When the outdoor working environment causes the electric meter box to vibrate, since the floating plate 505 covers most of the area of the liquid surface in the water collecting tank 501, the evaporation rate of the liquid in the water collecting tank 501 is reduced. It should be noted here that the floating plate 505 can swing with the liquid surface in the water collecting tank 501. After the vibration starts, the box body 101 will vibrate, and the liquid surface in the water collecting tank 501 will fluctuate, driving the floating plate 505 to move. Since the counterweight block 610 and the floating plate 505 are vertically suspended by the connecting rope 607, the middle part of the connecting rope 607 is supported by a support, forming a The center-branch double vertical pull rope connection structure is formed, and the movement of the floating plate 505 pulls the counterweight block 610 to move. The greater the vibration intensity, the greater the movement amplitude of the floating plate 505, and the greater the displacement of the counterweight block 610. When the displacement of the counterweight block 610 exceeds the threshold displacement, the controller adjusts the shock absorption strength of the shock absorption component to improve the shock absorption effect. In this case, the exposed area of the liquid surface is reduced, thereby reducing the volatilization rate. At the same time, the vibration intensity is monitored and the shock absorption component is dynamically adjusted to effectively improve the service life of the equipment inside the meter box.

[0036] In some optional specific embodiments, such as Figures 1 to 5 As shown, an air supply duct 103 is provided on the side of the main chamber 301, and an air supply fan 104 is installed between the air supply duct 103 and the main chamber 301. An air outlet 105 is opened on the bottom plate 303 of the main chamber 301, and the air outlet 105 is connected to the air blowing pipe 502, and an air blowing fan 5021 is installed inside the air blowing pipe 502. An air return duct 106 is provided on the other side of the main chamber 301 relative to the air supply duct 103, and an air return fan 107 is installed inside the air return duct 106. A collecting tank 403 is provided on the top of the main chamber 301, and a mounting plate 401 is provided above the collecting tank 403. Multiple heat exchange tubes 402 are detachably mounted on the mounting plate 401. The return air duct 106 is used to introduce the gas in the water collecting tank 501 into the heat exchange tube 402, and a return pipe 108 is connected between the collecting tank 403 and the water collecting tank 501. During use, internal gas circulation is achieved through the cooperation of multiple air ducts and fans.

[0037] In some optional specific embodiments, such as Figures 7 to 9As shown, a ball seat 602 is mounted on the base plate 303, which is adapted to be connected to a ball head 603. The ball head 603 is fixedly connected to a swing rod 604. A movable slot 605 is defined in the middle of the swing rod 604. A connecting bar 5052 is provided on the floating plate 505, which is adapted to fit within the movable slot 605. An opening is defined at the top of the ball seat 602, which communicates with the monitoring box 601. A connecting rope 607 extends downward along the movable slot 605 and is fixedly connected to the connecting bar 5052. An arched passage is defined in the monitoring box 601 to provide support for the connecting rope 607. During use, the floating plate 505 moves, pulling the connecting rope 607, which ultimately pulls the counterweight 610, causing the swing rod 604 to enhance the stability of the floating plate 505.

[0038] In some optional specific embodiments, such as Figure 7 As shown, a limit seat 606 is provided at the bottom of the pendulum rod 604 to prevent the floating plate 505 from slipping off the end of the pendulum rod 604. A pressure sensor is provided on the limit seat 606, which is electrically connected to the controller. The controller also has a water storage threshold. When the pressure sensor is in a pressed state for a continuous set time t, the controller captures the displacement of the counterweight 610 at that time. If the displacement of the counterweight 610 exceeds the water storage threshold, the controller determines that water needs to be added to the water collection tank 501. The pressure sensor on the limit seat 606 monitors whether the floating plate 505 is in contact with it. If it remains in contact for a continuous set time t, a secondary verification is performed by monitoring the current position of the counterweight 610, thereby determining that the position of the floating plate 505 is too low, that is, the liquid level is too low and water needs to be added.

[0039] In some optional specific embodiments, such as Figures 6 to 9 As shown, the shock-absorbing assembly includes a shock-absorbing seat 201 mounted on the bottom of the housing 101. A shock-absorbing spring 204 is connected to the shock-absorbing seat 201 and the bottom of the housing 101. The shock-absorbing spring 204 is also wrapped with a watertight bellows 203. The bellows 203 is connected to a water collection tank 501. The controller controls the water collection tank 501 to inject water into the bellows 203 to adjust the shock-absorbing effect of the shock-absorbing assembly. During use, the shock-absorbing spring 204 dampens the housing 101. When the controller is triggered, some water in the water collection tank 501 is introduced into the bellows 203, creating a fluid damping effect and thereby enhancing the shock absorption strength.

[0040] In some optional specific embodiments, such as Figures 6 to 9As shown, a spherical filter 503 is installed in the water collecting box 501, and the air in the main chamber 301 is discharged into the spherical filter 503. The spherical filter 503 is used to filter dust in the air. A water diversion pipe 504 is connected to the bottom of the spherical filter 503. The mouth of the water diversion pipe 504 is inserted into the spherical filter 503. A solenoid valve is provided at the mouth of the pipe. The water diversion pipe 504 extends downward to the shock absorber seat 201. The bottom end of the water diversion pipe 504 is connected to at least two groups of water distribution pipes 202, and a connecting hose 2021 is connected between the water distribution pipe 202 and the corrugated pipe 203. During use, the air in the main chamber 301 is introduced into the spherical filter 503, and the dust is retained in the spherical filter 503. The air escapes, and over time, the dust accumulates and settles in the spherical filter 503. When vibration occurs, the solenoid valve on the water inlet pipe 504 opens, and the water containing dust is introduced into the bellows 203, thereby improving the cleanliness of the water in the water collecting tank 501 and improving the dust washing effect.

[0041] In some optional specific embodiments, such as Figures 6 to 9 As shown, the bottom of the shock-absorbing seat 201 is provided with a discharge port 205, which is communicated with the interior of the bellows 203. A stop valve is installed on the discharge port 205. When the shock-absorbing work is completed, the water containing dust is discharged from the bellows 203 by opening the stop valve.

[0042] In some optional specific embodiments, such as Figures 1 to 5 As shown, a door 102 is hinged on the box body 101, and a groove for pulling is provided on the door 102.

[0043] In some optional specific embodiments, such as Figure 2 As shown, the gas outlet 105 is wide at the top and narrow at the bottom, which facilitates gas circulation.

[0044] In some optional embodiments, the water collection tank 501 is connected to a water collection hopper, which is located outside the housing 101 and is used to collect external rainwater. A filter is provided between the water collection hopper and the water collection tank 501 to filter out dust. A valve is also provided at the bottom of the water collection hopper, which is electrically connected to the controller. When the water level in the water collection tank 501 is too low, rainwater collected in the water collection hopper is injected into the water collection tank for replenishment.

[0045] In some optional specific embodiments, such as Figure 8 As shown, a relief opening 5051 is provided on the floating plate 505 for avoiding the blowing pipe 502 .

[0046] The working principle of the present invention is as follows: during daily operation, when the humidity sensor and temperature sensor in the main chamber 301 detect that the temperature or humidity exceeds the threshold, the hot and humid air inside the main chamber 301 is introduced into the water collecting tank 501, and the air in the main chamber 301 is cleaned and slightly cooled. The air that has been cleaned flows to the heat exchange tube 402 above the main chamber 301 and is cooled, and the water vapor in the air is condensed, and the condensed water flows back to the water collecting tank 501, and the cooled air circulates back to the main chamber 301, thereby achieving cooling, dust removal and dehumidification of the main chamber 301.

[0047] When the outdoor working environment causes the electric meter box to vibrate, since the floating plate 505 covers most of the area of the liquid surface in the water collecting tank 501, the evaporation rate of the liquid in the water collecting tank 501 is reduced. It should be noted here that the floating plate 505 can swing with the liquid surface in the water collecting tank 501. After the vibration starts, the box body 101 will vibrate, and the liquid surface in the water collecting tank 501 will fluctuate, driving the floating plate 505 to move. Since the counterweight block 610 and the floating plate 505 are vertically suspended by the connecting rope 607, the middle part of the connecting rope 607 is supported by a support, forming a The center-branch double vertical pull rope connection structure is formed, and the movement of the floating plate 505 pulls the counterweight block 610 to move. The greater the vibration intensity, the greater the movement amplitude of the floating plate 505, and the greater the displacement of the counterweight block 610. When the displacement of the counterweight block 610 exceeds the threshold displacement, the controller adjusts the shock absorption strength of the shock absorption component to improve the shock absorption effect. In this case, the exposed area of the liquid surface is reduced, thereby reducing the volatilization rate. At the same time, the vibration intensity is monitored and the shock absorption component is dynamically adjusted to effectively improve the service life of the equipment inside the meter box.

[0048] At the same time, the air in the main chamber 301 is introduced into the spherical filter 503, and the dust is retained in the spherical filter 503. The air escapes, and over time, the dust accumulates and settles in the spherical filter 503. When vibration occurs, the solenoid valve on the water inlet pipe 504 opens, and the water containing dust is introduced into the bellows 203, thereby improving the cleanliness of the water in the water collecting tank 501 and improving the dust washing effect.

[0049] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Within the scope of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
