Description

Technical Field

[0001] The invention belongs to the technical field of meter boxes, and in particular relates to a self-cleaning outdoor electricity meter box. Background Art

[0002] Outdoor power meter box is a facility used to install and protect power metering equipment, usually used in the power distribution network of the power system. Its main function is to measure and record power consumption for power billing and management.

[0003] In the Chinese invention patent with the announcement number CN221633118U, an outdoor electricity metering cabinet is disclosed. The temperature sensor transmits the signal to the controller. The controller can receive the signal of the temperature sensor and then control the opening and closing of the axial flow fan. In this way, the ventilation and heat dissipation of the outdoor electricity metering cabinet are guaranteed and the electricity is saved. The strip brush is driven by the motor to rotate. The bristles of the strip brush contact the surface of the first filter to remove the floating impurities accumulated on the surface of the first filter, thereby ensuring the air circulation at the first filter. The setting of the time control switch can start the motor at a fixed time to remove the floating impurities on the surface of the first filter, which effectively saves the consumption of electricity.

[0004] However, during the brushing process of the device, dust and floating impurities are easily scattered and then fall on the filter screen again, resulting in a poor effect of removing impurities. Summary of the invention

[0005] The purpose of the present invention is to provide a self-cleaning outdoor electricity meter box, which can effectively clean floating impurities on the filter screen and can promptly blow away the cleaned dust after cleaning to avoid it remaining on the filter screen again.

[0006] The technical solution adopted by the present invention to solve the above problem is: a self-cleaning outdoor power meter box, comprising: The box body has an axial flow fan and a controller installed on its inner wall. A mounting opening is provided on the side of the inner wall of the box body. A filter plate is installed inside the mounting opening. A brush plate is abutted against the filter plate. The bottom of the inner wall of the box is fixedly connected with a blowing assembly for blowing away impurities and dust floating on the filter plate; A driving assembly for driving the brush plate and the blowing assembly; The driving assembly includes a main driving part, a first driving part and a second driving part, wherein the first driving part and the second driving part are driven by the main driving part, the first driving part is used to drive the brush plate to reciprocate along the filter plate, and the second driving part is used to drive the blowing assembly to blow away the impurities and dust floating on the filter plate; Among them, through the synergistic effect of the blowing component and the movement of the brush plate, while the brush plate scrapes off impurities on the surface of the filter, the detached dust and floating objects can be immediately blown away from the filter area (especially blowing in a specific collection direction), avoiding secondary attachment of impurities due to airflow disturbance, and significantly improving the cleaning effect.

[0007] In addition, the directional airflow of the blowing component can cover the surface of the filter, forming a dual action mechanism of "cleaning + blowing away", which can more efficiently remove impurities compared to simple mechanical brushing.

[0008] By setting up a drive component, automatic blow-off processing can be achieved to reduce the frequency of manual cleaning, while avoiding filter clogging caused by long-term accumulation of impurities, thereby extending the service life of the filter and fan.

[0009] Compared with relying on timed cleaning, the blowing component is only activated when the brush plate moves (controlled uniformly by the main drive unit), avoiding the coordination inconsistency caused by independent drive. On the one hand, it ensures consistent cleaning effect, and on the other hand, it avoids the brush plate or blowing component working alone, which meets the design requirements of energy saving.

[0010] The blowing assembly includes a fanning plate and an inner brush detachably arranged on the fanning plate.

[0011] In particular, when the inner brush is provided, the blowing function of the fan plate on the filter plate will be weakened, but the inner brush can reciprocate to clean the inner side of the filter plate, and the filter plate can be deeply cleaned when the dust inventory is low.

[0012] A further preferred technical solution is that: a mounting box is fixedly connected to the bottom side of the box, and the drive assembly is installed inside the mounting box; The main driving part includes a motor, a long rod fixedly connected to the end of the motor rotor, and a first bevel gear fixedly connected to the end of the long rod; The first driving part includes a second bevel gear meshing with the first bevel gear, a screw rod penetrating the axis of the second bevel gear and rotatably connected to the bottom of the inner wall of the installation box at its bottom end, an adjustment cylinder threadedly connected to the screw rod, a fixed cylinder slidably connected to the outside of the adjustment cylinder and fixedly connected to the top of the installation box at its bottom, a U-shaped tube slidably connected to the outside of the adjustment cylinder and fixedly installed on the inner wall of the box body, and a piston rod slidably connected to the other end of the U-shaped tube relative to the adjustment cylinder; The brush plate is fixedly connected to the bottom end of the piston rod.

[0013] A further preferred technical solution is that: the main drive unit further includes a fourth bevel gear fixedly sleeved on the screw rod; A further preferred technical solution is that a bearing with a seat is installed on the outer side of the long rod, and the top of the bearing with a seat is fixedly connected to the top of the inner wall of the installation box.

[0014] A further preferred technical solution is that a support seat is installed at the bottom of the motor, and the bottom of the support seat is fixedly connected to the bottom of the inner wall of the installation box.

[0015] A further preferred technical solution is that a clamping block is fixedly connected to the surface of the adjusting cylinder, and a vertical clamping groove for the clamping block to move is provided on the inner wall of the fixing cylinder.

[0016] A further preferred technical solution is that a guide rail plate is fixedly connected to one side of the vertical tooth plate, a linear guide groove is provided on one side of the inner wall of the support plate, and the guide rail plate is slidably arranged inside the linear guide groove.

[0017] A further preferred technical solution is that: a through hole is provided on the top of the support plate for the vertical tooth plate to pass through.

[0018] A further preferred technical solution is that a mounting bearing is installed on the support plate, and the suspension rod is installed inside the mounting bearing.

[0019] A further preferred technical solution is that a collecting box located at the lower side of the filter plate is fixedly connected to the box body.

[0020] In summary, the present invention has the following benefits: 1. The core innovation of the technical solution of the present invention lies in that the secondary pollution problem of "sweeping and falling" in the prior art is solved by the timing coordination of mechanical cleaning and air flow blowing away, and the closed-loop control of the self-cleaning process of the filter is realized. By setting the blowing component, when the surface of the filter plate is cleaned, the motor is started to rotate the long rod, so that the fourth bevel gear rotates with the transmission rod through the third bevel gear, so that the turntable rotates. Under the action of the connecting rod, the vertical tooth plate reciprocates up and down in the vertical direction, and then the transmission gear deflects back and forth, so that the suspension rod swings up and down with the fan plate, thereby fanning the surface of the filter plate and blowing away the floating impurities and dust generated when brushing the surface of the filter plate, reducing the influence of floating impurities and dust on the cleaning of the filter plate and improving the cleaning effect of the device.

[0021] 2. The present invention sets a driving component, starts the motor, and the long rod rotates the first bevel gear, so that the second bevel gear rotates the lead screw, and then the adjusting cylinder moves upward along the fixed cylinder, so that the fixed cylinder moves toward the inside of the U-shaped tube. Under the action of atmospheric pressure, the piston rod drives the brush plate to brush the surface of the filter plate up and down, so as to brush away dust and impurities on the surface of the filter plate, facilitate the cleaning of the surface of the filter plate, and ensure the air circulation in the device.

[0071] Specifically, collection boxes are fixedly connected on both sides of the box body 1 to facilitate the collection of impurities, an axial flow fan 2 is installed on the top of the inner wall of the box body 1, and a controller 3 is installed on the right side of the inner wall of the box body 1. The functions and structures of the axial flow fan 2 and the controller 3 are consistent with the technical features recorded in the Chinese invention patent with announcement number CN221633118U. Installation ports are provided on both sides of the inner wall of the box body 1, and filter plates 4 are installed inside the installation ports. Installation boxes 5 are fixedly connected on both sides of the bottom of the inner wall of the box body 1, and a drive assembly is installed inside the installation box 5. Two symmetrically arranged blowing assemblies are fixedly connected to the bottom of the inner wall of the box body 1.

[0072] The main driving part includes a motor, a long rod, and a first bevel gear, wherein: Motor: provides driving power.

[0073] Long rod: fixedly connected to the rotor end of the motor, used to transmit the rotational power of the motor.

[0074] The first bevel gear is fixedly connected to the end of the long rod and transmits power to the first driving part through the bevel gear transmission.

[0075] The main driving part transmits the rotational power of the motor to the first driving part and the second driving part, and the driving system operates.

[0076] The first driving part includes a second bevel gear, a screw rod, an adjustment cylinder, a fixing cylinder, a U-shaped tube, and a piston rod, wherein: Second bevel gear: meshes with the first bevel gear to transmit power to the screw.

[0077] Screw rod: It passes through the axis of the second bevel gear, and the bottom end is fixed on the inner wall of the installation box, and drives the adjustment cylinder to move through thread transmission.

[0078] Adjustment cylinder: Threaded onto the lead screw, and position adjustment is achieved through its rotation.

[0079] Fixed cylinder: Slidingly connected to the outside of the adjusting cylinder, fixed on the top of the mounting box to limit the movement direction of the adjusting cylinder.

[0080] U-shaped tube: Slidingly connected to the outside of the adjustment cylinder, fixed on the inner wall of the box to provide guiding support.

[0081] Piston rod: Slidingly connected to the other end of the U-shaped tube, connected to the brush plate.

[0082] The first driving part realizes the lifting and displacement of the brush plate through the rotation of the screw rod to clean the surface of the filter plate.

[0083] Helical gears are a type of gear whose tooth surface is not perpendicular to the gear axis, but is arranged at a certain helical angle. The design of helical gears increases the number of contact teeth and makes the meshing smoother through the arrangement of spiral teeth.

[0084] The overall appearance of the U-tube is a "U" shape. This design is usually used to provide support and guidance, and can be made of metal or high-strength plastic to ensure its rigidity and durability. The size of the U-tube needs to match the size of the adjustment cylinder and the piston rod to ensure that it can slide smoothly. The setting of the U-tube changes the direction of the force transmitted by the adjustment cylinder, so that the original upward force is changed to downward, which is very helpful in simplifying the structure.

[0085] The main driving part also includes a fourth bevel gear fixedly sleeved on the screw rod, the second driving part includes a hollow support plate, a third bevel gear meshing with the fourth bevel gear, a transmission rod coaxially fixed with the third bevel gear, a turntable arranged at the end of the transmission rod, a connecting rod rotatably connected to the eccentric part of the turntable, a vertical tooth plate rotatably connected to the connecting rod relative to the other end of the turntable, a transmission gear meshed with the vertical tooth plate, a suspension rod fixedly connected to the inner wall of the support plate and penetrating through the axis of the transmission gear and rotatably connected to the inner wall of the support plate, and a fan plate fixedly sleeved on the suspension rod.

[0086] The turntable is set at the end of the transmission rod, and the eccentric structure converts the rotational motion into the reciprocating linear motion of the connecting rod. One end of the connecting rod is connected to the eccentric point of the turntable, converting the rotational motion of the turntable into the linear motion of the vertical tooth plate. In mechanical design, "eccentricity" means that the rotation axis or motion trajectory of a certain component is not at its geometric center. Specifically, in this scheme, eccentricity is usually used to convert rotational motion into linear motion. For example, the eccentric point on the turntable means that the connecting rod is not connected to the center of the turntable, but to a certain distance from the center. Due to this eccentric position, when the turntable rotates, the connecting rod will perform reciprocating linear motion instead of simply rotating. This mechanism is often used to convert continuous rotational motion into reciprocating motion, similar to the working principle of the crankshaft and piston in an engine. The eccentric design can achieve the switching between rotation and linear motion.

[0087] The boom is a horizontal rod that is fixedly connected to the axis of the transmission gear and rotatably mounted on the support plate. The other end of the boom relative to the transmission gear is usually rotatably connected to the inner wall of the support plate through a bearing or similar mechanical component to ensure that it can rotate freely. The main function of the boom is to transmit the rotational motion of the transmission gear to the fan plate. Through the connection with the transmission gear, the boom can drive the fan plate to rotate and generate airflow. The fan plate is usually fixedly sleeved on the end of the boom and may be in the form of a blade or multiple blades to optimize the generation of airflow. The design of the fan plate is similar to that of a fan blade, and its shape matches the boom, which can push air when the boom rotates. The main function of the fan plate is to generate airflow when the boom rotates to help remove dust and impurities cleaned by the brush plate. Through the action of the airflow, the fan plate can effectively blow away the dust on the surface of the filter plate and improve the cleaning effect.

Two blocks are fixedly connected to the surface of the adjusting cylinder 10, and two vertical slots for the blocks to move are provided on the inner wall of the fixed cylinder 11 to ensure the normal lifting and lowering movement of the adjusting cylinder 10 without deflection. The bottom of the fixed cylinder 11 is fixedly connected to the top of the mounting box 5, and one end of the adjusting cylinder 10 is slidably connected to a U-shaped tube 12, which is installed on the inner wall of the box body 1, and one end of the U-shaped tube 12 is slidably connected to a piston rod 13. The top of the inner wall of the mounting port is provided with a movable port for the piston rod 13 to pass through, which ensures the normal operation of the piston rod 13, and the bottom end of the piston rod 13 is fixedly connected to a brush plate 14, which abuts against the outer side of the filter plate 4.

[0089] The blowing assembly is used to blow away floating impurities and dust. The blowing assembly includes a support plate 15. The support plate 15 is slidably connected to a vertical tooth plate 16 inside. The top of the support plate 15 is provided with a through hole for the vertical tooth plate 16 to pass through, ensuring the normal operation of the vertical tooth plate 16. A guide plate is fixedly connected to one side of the vertical tooth plate 16. A linear guide groove is provided on one side of the inner wall of the support plate 15. The guide plate is slidably arranged inside the linear guide groove, ensuring the normal lifting and lowering movement of the vertical tooth plate 16. The surface of the vertical tooth plate 16 is meshed and connected with a transmission gear 17 at equal intervals. The shaft of the transmission gear 17 A suspension rod 18 is connected through the center, and mounting bearings are installed at equal intervals on the back of the support plate 15. The suspension rod 18 is installed inside the mounting bearing to ensure the stability of the suspension rod 18 when working. One end of the suspension rod 18 is rotatably connected to the back of the inner wall of the box body 1, and the other end of the suspension rod 18 is rotatably connected to the front of the inner wall of the support plate 15. A fan plate 19 is sleeved on the outside of the suspension rod 18. An inner brush 25 may be provided on the fan plate 19, or not, depending on specific needs. When the inner brush 25 is provided on the fan plate 19, one end of the inner brush 25 abuts against the inner side of the filter plate 4. A connecting rod 20 is rotatably connected to one side of the vertical tooth plate 16, and a rotating disk 21 is rotatably connected to one end of the connecting rod 20. A transmission rod 22 is fixedly connected to one side of the rotating disk 21. A third bevel gear 23 is sleeved on the outer side of the transmission rod 22, and a fourth bevel gear 24 sleeved on the outer side of the long rod 6 is meshed and connected on the surface of the third bevel gear 23.

[0090] The implementation principle of a self-cleaning outdoor electricity meter box in the embodiment of the present application is: start the motor, the long rod 6 rotates with the first bevel gear 7, so that the second bevel gear 8 rotates with the screw rod 9, and then the adjusting cylinder 10 moves upward along the fixed cylinder 11, so that the adjusting cylinder 10 moves toward the inside of the U-shaped tube 12. When the internal air pressure of the U-shaped tube 12 remains unchanged and remains airtight, the piston rod 13 carries the brush plate 14 to brush the surface of the filter plate 4 up and down, thereby brushing off the dust and impurities on the surface of the filter plate 4, facilitating the cleaning of the surface of the filter plate 4 and ensuring air circulation in the device.

[0091] When the long rod 6 rotates, the fourth bevel gear 24 rotates with the transmission rod 22 through the third bevel gear 23, so that the turntable 21 rotates. Under the action of the connecting rod 20, the vertical tooth plate 16 reciprocates up and down in the vertical direction, so that the transmission gear 17 deflects back and forth, and the suspension rod 18 swings up and down with the fan plate 19, thereby fanning the surface of the filter plate 4, blowing away the floating impurities and dust generated when brushing the surface of the filter plate 4, reducing the influence of the floating impurities and dust on the cleaning of the filter plate 4, and improving the cleaning effect of the device.

[0092] In particular, when there is less dust inside the box body 1, the wind force required for the fan plate 19 to blow is also low. At this time, it is possible to consider installing the inner brush 25 on the fan plate 19 and abutting against the inner side of the filter plate 4. In this way, when the suspension rod 18 swings the fan plate 19 up and down, the inner brush 25 can also clean the inside of the filter plate 4 at the same time, so that both the inside and outside of the filter plate remain clean.
