Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment, in particular to an electric meter with a moisture-proof function. Background Art

[0002] An electric meter is an instrument used to measure electrical energy. It is also called an watt-hour meter, fire meter, energy meter, or kilowatt-hour meter. It refers to an instrument that measures various electrical quantities.

[0003] When the electric meter is in use, its internal electronic components will generate a certain amount of heat. Usually, heat dissipation holes are opened on the box of the electric meter for heat dissipation. However, when used in coastal cities, the humidity in the air is relatively high. In order to prevent water vapor from entering the meter box and causing damage to the electric meter, which may easily cause short circuit damage to the electric meter, and to avoid affecting the service life of the electric meter, a dryer is usually placed in the meter box to absorb moisture in the air. For example, a dust-proof and moisture-proof electric meter box is announced with announcement number "CN212849322U". The dust-proof and moisture-proof electric meter box is provided with a fan on the meter box body, and a ventilation pipe connected to the outside and a drying box with a desiccant are provided in the box body below the fan, so that the air inside the meter box body can be kept circulated outward and dry, thereby effectively improving the dust-proof and moisture-proof performance of the meter box.

[0004] However, in actual use, the amount of desiccant adsorbed is certain, and staff are required to regularly check the use of the desiccant and replace it manually. Usually, in order to ensure normal internal heat dissipation, the meter box needs to be installed in a high and ventilated position, which makes it more troublesome to frequently replace the desiccant, and the heat dissipation effect is not good when it only relies on the heat dissipation holes. For this reason, we propose an electric meter with moisture-proof function. Summary of the invention

[0005] The object of the present invention is to provide an electric meter with moisture-proof function to solve the problems raised in the above background technology.

The desiccant in the storage box is placed on the placement plate. Under the gravity of the desiccant, the slide plate and the placement plate move downward. With normal operation, the moisture in the air entering the box is adsorbed and removed by the desiccant on the top of the placement plate. After long-term use, the desiccant adsorbs a certain amount of moisture, and the overall gravity increases. The slide plate moves downward a certain distance, and the top rod is inserted into the slide plate through the round hole at the bottom of the slide plate and abuts against the card rod, pushing the card rod to move to the side away from the placement plate, so that the card rod withdraws from the card slot on the side of the placement plate, thereby releasing the limit on the placement plate. Under the action of gravity, the placement plate can swing downward at the position hinged to the slide plate, thereby pouring out the used desiccant.

[0008] Preferably, the driving part includes a guide rod, which is fixed on the inner wall of the box body, and a slider is slidably installed on the surface of the guide rod, and the top of the slider is hinged with a push rod, and the end of the push rod away from the slider is hinged with a moving block, and the moving block is slidably installed on the side of the bracket, one end of the bracket is hinged on the inner wall of the control box, and the other end of the bracket is hinged on the bottom of the bearing block, and the bearing block is slidably installed on the bottom of the support plate, and the support plate is slidably installed on the inner wall of the control box.

When the half gear meshes with the teeth and contacts the teeth, the teeth swing to the side of the spring piece 1 at the position hinged with the baffle plate, and the baffle plate will not be driven to move. When the slide plate moves upward with the L-shaped slide bar, the L-shaped slide bar controls the sleeve to rotate one circle in the opposite direction, and the sleeve drives the half gear to rotate in the opposite direction. At this time, the half gear meshes with the teeth. Since the teeth are contacted by the blocking block, the baffle plate is pushed to move, so that the baffle plate cannot continue to block the through hole at the bottom of the storage box. The toggle rod is rotated to discharge the desiccant in the storage box to the top of the slide plate and the placement plate to complete the replacement of the desiccant. At the same time, when the slide plate is completely reset, the half gear rotates one circle, and the half gear is no longer meshed with the teeth. Under the action of spring 2, the baffle plate is reset to block the through hole at the bottom of the storage box again, so that the desiccant cannot be discharged further, and the replacement of the desiccant is completed. Manual replacement is not required for the staff, and the desiccant in the storage box can be replaced after a certain period of time.

When the connecting rod is no longer limited, under the action of the spiral spring, the connecting rod rotates clockwise, and the connecting rod drives the first pawl on its surface to rotate clockwise together. At this time, the first pawl abuts on the inclined groove of the resistance block. At this time, the first pawl cannot directly apply the inner side of the resistance block close to the connecting sleeve, and the first pawl is abutted by the inclined groove of the resistance block, causing the first pawl to swing, thereby achieving the goal of making the first pawl and the ratchet wheel no longer engage.

When the driving rod 49 rotates clockwise, the driving rod 49 drives the linkage rod 81 to rotate counterclockwise through the ratchet 83 arranged on the surface of the driving rod 49 and is stuck on the pawl 82. At this time, the linkage rod 81 winds up the spiral spring 84. In this process, the pawl 82 on the surface of the linkage rod 81 abuts on the abutment block 89, and because the pawl 86 on the surface of the rotating ring 85 is stuck on the ratchet 87 on the inner wall of the box body 1 The pawl 82 is pressed against the inner side of the stopper 89, and the pawl 82 is pressed against the stopper 89, so that the pawl 82 is pressed against the stopper 89, and the stopper 82 is pressed against the stopper 89, so that the pawl 82 is pressed against the stopper 89, and the stopper 82 is pressed against the stopper 89, so that the pawl 82 is pressed against the stopper 89, and the stopper 82 is pressed against the stopper 89, so that the pawl 82 is pressed against the stopper 89, and the stopper 82 is pressed against the stopper 89, so that the pawl 82 is pressed against the stopper 89, and the stopper 82 is pressed against the stopper 89, so that the pawl 82 is pressed against the stopper 89, and the stopper 82 is pressed against the stopper 89, so that the pawl 82 is pressed against the stopper 89, and the stopper 82 is pressed against the stopper 89, so that the pawl 82 is pressed against the stopper 89, and the stopper 82 is pressed against the stopper 89, 89 drives the swivel ring 85 to rotate clockwise, and the connecting rod 81 drives the driving gear 811 to rotate. The driving gear 811 controls the connecting rack 812 to move to the side away from the center of the box body 1. The connecting rack 812 can push the slider 32 along the guide rod 31 to move toward the side close to the bracket 35 through the connecting rod 813, so as to push the support plate 37 upward by controlling the bracket 35. When working normally, as the swing plate 411 swings normally, the driving rod 49 is controlled to rotate clockwise, and the driving rod 49 drives the connecting rod 81 to rotate counterclockwise, so as to control the connecting rack 812 to move toward the side close to the center of the box body 1, and the support plate 37 can be controlled to move downward through the slider 32, so that the support plate 37 no longer conflicts with the placement plate 23 and the slide plate 22.

[0024] A limit assembly 9 is arranged inside the box body 1, and the limit assembly 9 includes an L-shaped limit rod 91, which passes through the top rod 28 and is slidably connected to the top rod 28. A spring three 92 is fixed to the bottom of the top rod 28, and one end of the spring three 92 away from the top rod 28 is fixedly connected to the L-shaped limit rod 91. A clamping block 93 is hinged at the bottom of the connecting rack 812, a torsion spring 94 is fixed to one side of the clamping block 93, and a fixing block 95 is fixed to the other side of the clamping block 93. The end of the torsion spring 94 away from the clamping block 93 is fixed to the bottom of the connecting rack 812. Under the action of the fixing block 95, the clamping block 93 can only swing to the side away from the fixing block 95 at the position hinged to the connecting rack 812. The L-shaped limit rod 91 and the block 93 interfere with each other to limit the connecting rack 812, so that the connecting rack 812 cannot move to the side away from the center of the box body 1, so that the connecting rack 812 limits the connecting rod 81 through the driving gear 811, so that the connecting rod 81 cannot rotate clockwise. When the desiccant 25 absorbs a certain amount of moisture and the gravity increases, the slide plate 22 slides downward a certain distance, and the top rod 28 is inserted into the slide plate 22 through the circular hole at the bottom of the slide plate 22 and interferes with the block 26. At this time, the L-shaped limit rod 91 is interfered and moved downward, and the L-shaped limit rod 91 no longer interferes with the block 93, thereby releasing the limit on the connecting rack 812 and the connecting rod 81.

[0025] Based on the above embodiment, after a certain amount of desiccant 25 is placed in the storage box 24, the storage box 24 is closed and the box body 1 is installed. With the continuous use of the box body 1, when a strong wind blows, the wind blows on the swing plate 411, causing the swing plate 411 to swing. When the swing plate 411 swings to the right, the swing plate 411 drives the rotating rod 42 and the large gear 43 to rotate counterclockwise. At this time, the small gear 44 and the connecting block 45 are on the left side of the sliding frame 46, and the small gear 44 is in a state of meshing with the driven gear 47. Then, the small gear 44 is driven by the large gear 43 to rotate clockwise, and the small gear 44 drives the driven gear 47 to rotate counterclockwise. The driven gear 47 drives the driving gear 48 to rotate clockwise. When the swing plate 411 swings to the right, the small gear 44 and the connecting block 45 are on the left side of the sliding frame 46. The small gear 44 is in a state of meshing with the driven gear 47. Then, the small gear 44 is driven by the large gear 43 to rotate clockwise, and the small gear 44 drives the driven gear 47 to rotate counterclockwise. The driven gear 47 drives the driving gear 48 to rotate clockwise. When swinging left, the large gear 43 rotates clockwise. At this time, the large gear 43 abuts against the small gear 44. Since the sliding frame 46 cannot abut against the connecting block 45, the small gear 44 first slides along the sliding frame 46 with the connecting block 45 to the right side of the sliding frame 46. As the small gear 44 rotates counterclockwise, the small gear 44 gradually meshes with the driving gear 48, so that the driving gear 48 rotates clockwise, so that no matter whether the swing plate 411 swings left or right, the driving gear 48 can be driven to rotate clockwise. The driving gear 48 drives the driving rod 49 and the connecting plate 410 to rotate. When the connecting plate 410 rotates in the box body 1, the flow rate of the gas in the box body 1 can be increased, and the airflow inside the box body 1 can be disturbed, thereby further improving its heat dissipation effect.

[0026] When the driving rod 49 rotates clockwise, the driving rod 49 drives the connecting rod 81 to rotate counterclockwise by clamping the ratchet 83 arranged on the surface on the pawl 82. At this time, the connecting rod 81 reels the spiral spring 84. In this process, the pawl 82 on the surface of the connecting rod 81 abuts on the abutment block 89, and because the pawl 86 on the surface of the rotating ring 85 is clamped on the ratchet 87 on the inner wall of the box body 1, the rotating ring 85 cannot rotate counterclockwise together. Then the pawl 82 pushes the abutment block 89 to retract into the connecting sleeve 88, which will not affect the normal engagement of the pawl 82 and the ratchet 83. The driving rod 49 drives the connecting rod 81 to rotate counterclockwise, which can control the connecting rack 812 to move to the side close to the center of the box body 1, and the support plate 37 can be controlled to move downward through the slider 32, so that the support plate 37 no longer abuts the placement plate 23 and the slide plate 22.

[0027] After being used for a period of time, the desiccant 25 absorbs a certain amount of moisture, the overall gravity increases, the slide plate 22 moves downward a certain distance, the top rod 28 is inserted into the slide plate 22 through the round hole at the bottom of the slide plate 22 and abuts on the card rod 26, pushing the card rod 26 to move to the side away from the placement plate 23, so that the card rod 26 withdraws from the card slot on the side of the placement plate 23, thereby releasing the limit on the placement plate 23. Under the action of gravity, the placement plate 23 can swing downward at the position hinged to the slide plate 22, thereby pouring down the used desiccant 25, and the used desiccant 25 falls into the collection box 10 for collection. At this time, the L-shaped limit rod 91 is abutted and moved downward, and the L-shaped limit rod 91 no longer conflicts with the block 93, thereby releasing the limit on the connecting rack 812 and the connecting rod 81.

[0028] When the connecting rod 81 is no longer limited, under the action of the spiral spring 84, the connecting rod 81 rotates clockwise, and the connecting rod 81 drives the ratchet 82 on its surface to rotate clockwise together. At this time, the ratchet 82 abuts against the inclined groove of the abutment block 89. At this time, the ratchet 82 cannot directly apply pressure to the abutment block 89 toward the inner side of the side close to the connecting sleeve 88, and then the ratchet 82 is abutted by the inclined groove of the abutment block 89, so that the ratchet 82 swings, thereby achieving the purpose of making the ratchet 82 and the ratchet 83 are no longer engaged. At this time, the ratchet 82 drives the rotating ring 85 to rotate clockwise by pushing the resistance block 89, and the connecting rod 81 drives the driving gear 811 to rotate. The driving gear 811 controls the connecting rack 812 to move to the side away from the center of the box body 1. The connecting rack 812 can push the slider 32 along the guide rod 31 to move toward the side close to the bracket 35 through the connecting rod 813, thereby controlling the bracket 35 to push the support plate 37 to move upward.

[0029] The support plate 37 first contacts the placement plate 23, causing the placement plate 23 to move upward and reset at the position hinged with the slide plate 22. When the placement plate 23 is fully reset, the support plate 37 pushes the slide plate 22 to move upward by contacting the placement plate 23 and the slide plate 22. When the push rod 28 is no longer stuck on the clamping rod 26, the clamping rod 26 can pop out and be clamped into the clamping groove on the side of the placement plate 23 under the action of the spring 27 to limit the placement plate 23.

[0030] The desiccant 25 in the storage box 24 is replaced by the desiccant 25 in the storage box 24.

[0031] When the wind blows again, the swing plate 411 can be swung to control the driving rod 49 to rotate, thereby controlling the connecting rack 812 to reset, so that the support plate 37 no longer conflicts with the slide plate 22 and the placement plate 23, and the reset is completed.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
