Description

Technical Field

[0001] This invention relates to the field of electrical energy metering equipment technology, specifically an electrical energy metering box. Background Technology

[0002] Electricity metering boxes are important devices in power systems used to measure electrical energy. They contain various electrical components and controllers. During operation, electricity metering boxes require good heat dissipation to ensure the normal operation of electrical components. At the same time, they must prevent external dust, insects, and other contaminants from entering the box, so as not to affect the performance and lifespan of the electrical components. Poor heat dissipation will cause the component temperature to rise, affecting the metering accuracy and lifespan, and may even cause malfunctions.

[0003] Under normal weather conditions, traditional electricity metering boxes typically rely on natural heat dissipation or simple fan cooling to reduce internal temperature. However, the heat dissipation problem becomes even more pronounced in rainy weather. Rainwater can enter the box through air inlets and outlets, causing electrical components to become damp or even short-circuit, severely impacting the normal operation of the equipment. Furthermore, the high humidity in rainy weather, coupled with the lack of effective air filtration and quality control measures in traditional metering boxes, makes them susceptible to insect infestation and air pollution, further affecting the stability and reliability of the equipment.

[0004] To overcome these problems, some improved electricity metering box designs have incorporated waterproofing measures, such as installing waterproof filters at the air inlet and heat dissipation vents. However, while these designs can prevent rainwater from entering to some extent, they cannot fully utilize the low temperature characteristics of rainwater to aid heat dissipation. On rainy days, the temperature of outside rainwater is usually low; if this characteristic can be properly utilized, it will provide an efficient and energy-saving solution for the heat dissipation of electricity metering boxes.

[0005] Therefore, there is an urgent need for an electricity metering box to solve the above problems. Summary of the Invention

[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] In the embodiments of this invention, please refer to Figures 1 to 9 An electricity metering box includes a box body 1, a door on the front of the box body 1, symmetrical air inlets on the side walls of the box body 1, and heat dissipation holes at the bottom of the box body 1. Electrical components and a controller are installed inside the box body 1. The box body 1 also includes:

[0063] The bottom plate 5 is connected to the bottom outer wall of the box 1. The bottom plate 5 is U-shaped and has a bottom hole.

[0064] The connecting frame 6 is connected to the bottom plate 5 at its bottom end and to the outer wall of the box 1. The connecting frame 6, the bottom plate 5 and the outer wall of the box 1 form a U-shaped space.

[0065] The bottom of the filter frame 7 is connected to the top of the connecting frame 6, and the top is connected to the outer wall of the housing 1. The filter frame 7 is inclined.

[0066] A water-cooling mechanism 8 is used to cool the internal components of the housing 1 in rainy weather. The water-cooling mechanism 8 includes: a motor 81 connected to the bottom of the housing 1; a transmission belt 82, one end of which is connected to the output end of the motor 81; a threaded rotating rod 83 connected to the other end of the transmission belt 82, the threaded rotating rod 83 passing through the bottom plate 5 and extending into the U-shaped space, the threaded rotating rod 83 being rotatably connected to the bottom plate 5; a bottom hole plugging assembly 84, one end of which is connected to the threaded rotating rod 83, and the other end of which is connected to the bottom plate 5, used to plug the bottom hole on the bottom plate 5; and an air hole plugging assembly 85. One end is connected to the threaded rotating rod 83, and the other end is connected to the outer wall of the housing 1, used to block the air inlet on the housing 1; the limiting component 86 is connected to the outer wall of the housing 1, used to limit the air hole blocking component 85; the cleaning component 87 is connected to the connecting frame 6, used to clean the filter frame 7; the rain sensor 88 is connected to the outer wall of the connecting frame 6, used to monitor the external rainwater and control the start and stop of the motor 81; the liquid level sensor 89 is located in the U-shaped space and connected to the outer wall of the housing 1, used to monitor the liquid level in the U-shaped space and control the start and stop of the cleaning component 87.

[0067] Under normal weather conditions (e.g., sunny days), the vent plugging component 85 is disengaged from the air inlet, and the air inlet is in the open state; the bottom hole plugging component 84 is disengaged from the bottom hole, and the bottom hole is in the open state; outside air enters the interior of the housing 1 through the air inlet and flows out through the heat dissipation holes to dissipate heat from the electrical components inside the housing 1.

[0068] When the rain sensor 88 detects rain outside, it transmits a signal to the controller (not shown in the figure). The controller controls the motor 81 to start, which drives the threaded rotating rod 83 to rotate via the transmission belt 82. This causes the bottom hole blocking component 84 and the air hole blocking component 85 to move. The bottom hole blocking component 84 blocks the bottom hole on the bottom plate 5, and the air hole blocking component 85 blocks the air inlet on the housing 1. Outside rainwater enters the U-shaped space for collection. The cool rainwater absorbs the heat emitted by the electrical components inside the housing 1, ensuring a cooling effect. The liquid level sensor 89 monitors the liquid level in the U-shaped space. When the liquid level in the U-shaped space increases to a certain height, the cleaning component 87 works to extract the rainwater from the U-shaped space and clean the filter frame 7.

[0069] Please see Figure 2 , Figure 3 and Figure 5 In this embodiment, filters are provided in both the bottom hole and the heat dissipation hole to prevent mosquitoes from entering the interior of the box 1; a heat dissipation fan 2 is installed in the heat dissipation hole to accelerate the airflow rate inside the box 1; a fixing frame 3 is provided on the inner wall of the box 1, and an activated carbon plate 4 is slidably engaged in the fixing frame 3, with the activated carbon plate 4 located on the air inlet and the heat dissipation hole.

[0070] Under normal weather conditions, the cooling fan 2 inside the heat dissipation hole works to accelerate the air flow rate inside the box 1 and dissipate heat through the air inlet and heat dissipation hole. At the same time, the activated carbon plate 4 filters the air entering the box 1, adsorbs moisture and odors, and ensures the air quality inside the box 1. The fixed frame 3 makes it easy to install and remove the activated carbon plate 4.

[0071] As one embodiment of the present invention, please refer to Figure 3 , Figures 5 to 7 The bottom hole plugging assembly 84 includes:

[0072] Thread groove 845 is provided on threaded rotating rod 83;

[0073] Threaded sleeve 841 is threadedly connected to threaded groove 845;

[0074] A blocking plate 842 is connected to a threaded sleeve 841, and the blocking plate 842 is located at the top of the bottom hole;

[0075] The limiting rod 843 is connected to the bottom plate 5 at its bottom end and to the outer wall of the box 1 at its top end. The limiting rod 843 is slidably engaged with the blocking plate 842.

[0076] Spring 844 is sleeved on limit rod 843, with its bottom end connected to block plate 842 and its top end connected to the outer wall of box 1.

[0077] Under normal weather conditions, the blocking plate 842 is separated from the bottom hole, the threaded sleeve 841 is located at the top of the threaded groove 845 and is connected to the unthreaded part of the threaded rotating rod 83, and the spring 844 is in a compressed state.

[0078] When the rain sensor 88 detects rain, it transmits a signal to the controller. The controller then starts the motor 81, which drives the threaded rotating rod 83 to rotate via the transmission belt 82. Since the spring 844 is in a compressed state, it provides pressure, causing the threaded sleeve 841 to connect with the threaded groove 845. This causes the threaded rotating rod 83 to drive the threaded sleeve 841 and the blocking plate 842 to move downwards synchronously. The limit rod 843 ensures that the threaded sleeve 841 and the blocking plate 842 move downwards stably. During the downward movement of the blocking plate 842, the spring 844 is gradually stretched. When the blocking plate 842 moves to abut against the bottom plate 5, it seals the bottom hole. At this time, the threaded sleeve 841 moves to disengage from the threaded groove 845, and the spring 844 is in a stretched state. At this time, the blocking plate 842 can no longer move downwards.

[0079] When the weather returns to normal, the controller controls the motor 81 to rotate in the reverse direction. At this time, the spring 844 provides tension, causing the threaded sleeve 841 to reconnect with the threaded groove 845, so that the threaded sleeve 841 and the plug plate 842 move upward synchronously and return to the normal state.

[0080] In this embodiment, a sealing gasket is provided at the bottom of the blocking plate 842 to improve the sealing performance between the blocking plate 842 and the bottom plate 5.

[0081] As one embodiment of the present invention, please refer to Figure 3 , Figures 5 to 8 The pore plugging assembly 85 includes:

[0082] A bidirectional threaded groove 854 is provided on the threaded rotating rod 83;

[0083] Threaded sleeve rod 851, the threaded sleeve rod 851 is provided in two sets, and is threadedly connected to the bidirectional threaded groove 854 respectively;

[0084] The second blocking plate 852 is connected to the second threaded sleeve rod 851 and is slidably connected to the outer wall of the housing 1;

[0085] Spring 2 853 is connected at both ends to the two sets of threaded sleeve rods 2 851 respectively.

[0086] Under normal weather conditions (e.g., sunny day), the two sets of blocking plates 852 are in a separated state, the air inlet is open, the threaded sleeve rod 851 is located on the upper and lower sides of the bidirectional threaded groove 854 and is connected to the unthreaded part of the threaded rotating rod 83, and the spring 853 is in a stretched state.

[0087] When the rain sensor 88 detects rain, it transmits a signal to the controller. The controller then starts the motor 81, which drives the threaded rotating rod 83 to rotate via the transmission belt 82. Since the second spring 853 is in a stretched state, it provides tension, causing the threaded sleeve rod 851 to connect with the bidirectional threaded groove 854. This causes the threaded rotating rod 83 to move the two sets of threaded sleeve rods 851 and the two sets of blocking plates 852 closer together. As the blocking plates 852 move, the second spring 853 is gradually compressed. When the two sets of blocking plates 852 move to abut against each other, they block the air inlet. At this time, the threaded sleeve rod 851 moves to disengage from the bidirectional threaded groove 854, and the second spring 853 is in a compressed state. The blocking plates 852 can no longer move.

[0088] When the weather returns to normal, the controller controls the motor 81 to rotate in the reverse direction. At this time, the spring 853 provides pressure, causing the threaded sleeve 851 to reconnect with the bidirectional threaded groove 854, so that the two sets of threaded sleeves 851 and the two sets of blocking plates 852 move away from each other and return to the normal state.

[0089] In this embodiment, the second sealing gasket is provided on the second blocking plate 852 to improve the sealing performance between the second blocking plate 852 and the outer wall of the box 1.

[0090] As one embodiment of the present invention, please refer to Figures 5 to 8 The limiting component 86 includes:

[0091] Air frame 861 is located within the U-shaped space and is connected to the outer wall of box 1;

[0092] The power assembly 862 is connected to the inside of the air frame 861 at one end and to the outer wall of the housing 1 at the other end.

[0093] The trachea 863 is connected at one end to the inside of the air frame 861;

[0094] Sliding rod 864 is slidably connected to the other end of trachea 863;

[0095] The trapezoidal block 865 is connected to the sliding rod 864 on one side, and the other side of the trapezoidal block 865 is a slanted structure;

[0096] The power assembly 862 includes:

[0097] The top of the connecting cylinder 8621 is connected to the inside of the air frame 861;

[0098] Sliding rod 8622 is slidably connected to the inner wall of connecting cylinder 8621;

[0099] The float plate 8623 is connected to the bottom end of the sliding rod 8622;

[0100] The positioning block 8624 is connected to the outer wall of the box 1 and abuts against the bottom of the floating plate 8623.

[0101] In rainy weather, the first blocking plate 842 blocks the bottom hole, and the second blocking plate 852 blocks the air inlet. At this time, rainwater enters the U-shaped space through the filter frame 7 for collection. The cold rainwater absorbs the heat emitted by the electrical components inside the box 1. As time goes by, the amount of rainwater in the U-shaped space gradually increases, and the liquid level gradually rises. Because the float plate 8623 has buoyancy, the rise in liquid level drives the float plate 8623 to move upward synchronously. The float plate 8623 drives the second sliding rod 8622 to move upward, forcing the gas in the air frame 861 into the air pipe 863. This causes the first sliding rod 864 and the trapezoidal block 865 to move laterally synchronously. The trapezoidal block 865 abuts against the two sets of second blocking plates 852 on the opposite side, limiting the position of the second blocking plate 852.

[0102] When the motor 81 rotates in the reverse direction, the trapezoidal block 865 limits the movement of the second blocking plate 852, preventing it from moving away initially. The first blocking plate 842 separates from the bottom plate 5, and rainwater flows out from the bottom hole. When the liquid level drops to the bottom of the float 8623, the float 8623 moves downward under its own weight, causing the trapezoidal block 865 to move in the reverse direction and gradually separate from the second blocking plate 852. When the float 8623 moves to abut against the positioning block 8624, the float 8623 stops moving. At this time, the trapezoidal block 865 separates from the second blocking plate 852, and the second blocking plate 852 begins to move.

[0103] In this embodiment, the lowest position of the float plate 8623 is located at the bottom of the air inlet, and there is a certain distance between them, so that when the two sets of blocking plates 852 are separated, rainwater in the U-shaped space will not enter the interior of the box 1 through the air inlet.

[0104] In this embodiment, a sealing ring is provided on the sliding rod 8622 to improve the sealing between the sliding rod 8622 and the connecting cylinder 8621.

[0105] As one embodiment of the present invention, please refer to Figures 3 to 6 , Figure 9 The cleaning assembly 87 includes:

[0106] The fixing cylinder 871 is connected to the outer wall of the connecting frame 6;

[0107] Cylinder 872 is connected to the outer wall of connecting frame 6;

[0108] Piston block 873 is slidably engaged with the inner wall of fixed cylinder 871 and connected to the output end of cylinder 872;

[0109] The water inlet pipe 874 is connected to the inside of the fixed cylinder 871 at its top end. The water inlet pipe 874 passes through the connecting frame 6 and extends to the bottom of the U-shaped space.

[0110] The water outlet pipe 875 is connected to the inside of the fixed cylinder 871 at one end. The water outlet pipe 875 passes through the connecting frame 6 and extends to the top of the U-shaped space.

[0111] The water spray pipe 876 is located at the top of the U-shaped space and is connected to the outer wall of the box 1. The water spray pipe 876 is connected to the other end of the water outlet pipe 875. Several sets of water spray holes are opened on the water spray pipe 876. The water spray pipe 876 is U-shaped.

[0112] The inlet pipe 874 is equipped with a one-way valve, and the outlet pipe 875 is equipped with a two-way valve.

[0113] As time goes by, the amount of rainwater in the U-shaped space gradually increases, and the liquid level gradually rises. When the liquid level sensor 89 detects that the liquid level in the U-shaped space has reached a certain height, the cleaning component 87 is activated. The cylinder 872 pushes the piston block 873 to move longitudinally back and forth in the fixed cylinder 871, drawing the rainwater at the bottom of the U-shaped space into the fixed cylinder 871 through the water inlet pipe 874, and then pressurizing it into the water spray pipe 876 through the water outlet pipe 875. The water is then sprayed onto the filter frame 7 through the spray holes to rinse the filter frame 7 from the inside out, allowing the rainwater to flow to the outside.

[0114] As the rainwater in the U-shaped space absorbs heat over a period of time, its heat increases and the cooling effect decreases. The cleaning component 87 extracts some of the rainwater out of the U-shaped space, reducing the amount of rainwater in the U-shaped space. At this time, outside rainwater can continue to enter the U-shaped space. The outside rainwater temperature is lower, and after entering the U-shaped space, the cooling effect can be improved.

[0115] The working principle of this invention is as follows: Under normal weather conditions, the first blocking plate 842 is separated from the bottom hole, the first threaded sleeve 841 is located at the top of the first threaded groove 845 and is connected to the unthreaded part of the threaded rotating rod 83, the first spring 844 is in a compressed state, the two sets of second blocking plates 852 are separated, the air inlet is open, the second threaded sleeve 851 is located on the upper and lower sides of the bidirectional threaded groove 854 and is connected to the unthreaded part of the threaded rotating rod 83, and the second spring 853 is in a stretched state.

[0116] Under normal weather conditions, the cooling fan 2 inside the heat dissipation hole works to accelerate the air flow rate inside the box 1 and dissipate heat through the air inlet and heat dissipation hole. At the same time, the activated carbon plate 4 filters the air entering the box 1, adsorbs moisture and odors, and ensures the air quality inside the box 1.

[0117] When the rain sensor 88 detects rain, it transmits a signal to the controller. The controller then starts the motor 81, which drives the threaded rotating rod 83 to rotate via the transmission belt 82. Since the spring 844 is compressed, it provides pressure, causing the threaded sleeve 841 to connect with the threaded groove 845. This causes the threaded rotating rod 83 to drive the threaded sleeve 841 and the blocking plate 842 to move downwards synchronously. The limit rod 843 ensures the stable downward movement of the threaded sleeve 841 and the blocking plate 842. During the downward movement of the blocking plate 842, the spring 844 is gradually stretched. When the blocking plate 842 reaches contact with the bottom plate 5, it seals the bottom hole. At this point, the threaded sleeve 841... When the spring moves to disengage from the threaded groove 845, the spring 844 is in a stretched state, and the blocking plate 842 can no longer move downwards. Since the spring 853 is in a stretched state, it provides tension, causing the threaded sleeve 851 to be threadedly connected to the bidirectional threaded groove 854. This causes the threaded rotating rod 83 to drive the two sets of threaded sleeves 851 and the two sets of blocking plates 852 to move closer to each other. During the movement of the blocking plate 852, the spring 853 is gradually compressed. When the two sets of blocking plates 852 move to abut against each other, they block the air inlet. At this time, the threaded sleeve 851 moves to disengage from the bidirectional threaded groove 854, the spring 853 is in a compressed state, and the blocking plate 852 can no longer move.

[0118] At this time, rainwater enters the U-shaped space through the filter frame 7 for collection. The cool rainwater absorbs the heat emitted by the electrical components inside the box 1. As time goes by, the amount of rainwater in the U-shaped space gradually increases and the liquid level gradually rises. Since the float plate 8623 has buoyancy, the rise in liquid level drives the float plate 8623 to move upward synchronously. The float plate 8623 drives the sliding rod 8622 to move upward, forcing the gas in the air frame 861 into the air pipe 863. This causes the sliding rod 864 and the trapezoidal block 865 to move laterally synchronously. The trapezoidal block 865 abuts against the two sets of blocking plates 852 on the opposite side, limiting the blocking plates 852.

[0119] When the liquid level sensor 89 detects that the liquid level in the U-shaped space has reached a certain height, the cleaning component 87 is activated. The cylinder 872 pushes the piston block 873 to move longitudinally and reciprocally in the fixed cylinder 871, drawing the rainwater at the bottom of the U-shaped space into the fixed cylinder 871 through the inlet pipe 874, and then pressurizing it into the spray pipe 876 through the outlet pipe 875. The water is then sprayed onto the filter frame 7 through the spray holes to rinse the filter frame 7 from the inside out, allowing the rainwater to flow to the outside.

[0120] As the rainwater in the U-shaped space absorbs heat over a period of time, its heat increases and the cooling effect decreases. The cleaning component 87 extracts some of the rainwater out of the U-shaped space, reducing the amount of rainwater in the U-shaped space. At this time, outside rainwater can continue to enter the U-shaped space. The outside rainwater temperature is lower, and after entering the U-shaped space, the cooling effect can be improved.

[0121] When the weather returns to normal, the controller controls the motor 81 to rotate in reverse. At this time, the spring 844 provides tension, so that the threaded sleeve 841 reconnects with the threaded groove 845, and the threaded sleeve 841 and the plug plate 842 move upward synchronously, returning to the normal state.

[0122] Due to the limiting effect of trapezoidal block 865, the second blocking plate 852 will not move away initially. The first blocking plate 842 separates from the bottom plate 5, and rainwater flows out from the bottom hole. When the liquid level drops to the bottom of the float plate 8623, the float plate 8623 moves downward under its own weight, causing the trapezoidal block 865 to move in the opposite direction and gradually separate from the second blocking plate 852. When the float plate 8623 moves to abut against the positioning block 8624, the float plate 8623 stops moving. At this time, the trapezoidal block 865 separates from the second blocking plate 852, and the second blocking plate 852 moves. The second spring 853 provides pressure, causing the second threaded sleeve rod 851 to reconnect with the bidirectional threaded groove 854, so that the two sets of second threaded sleeve rods 851 and the two sets of second blocking plates 852 move away from each other and return to the normal state.
