Description

Technical Field

[0001] This application relates to the field of metering box technology, and more specifically, to a three-phase multi-position metal metering box. Background Technology

[0002] Three-phase multi-position metal metering boxes are a collection of metering instruments and auxiliary equipment necessary for measuring electrical energy, including electricity meters, voltage and current transformers and their secondary circuits, electricity metering panels, cabinets, boxes, etc.

[0003] However, three-phase multi-position metering boxes are usually installed outdoors, in basements, electrical wells, and other environments. In seasons with large temperature differences between day and night or high air humidity, the temperature inside the box may be lower than the dew point temperature of the environment. This causes water vapor in the air to condense into water droplets on the cold metal box walls, copper terminal blocks, and meter housings, which can lead to electrical equipment failure. At the same time, in order to prevent dust and insects, dust filters are usually installed at the ventilation openings. However, long-term use may cause the dust filters to become clogged, which will affect the heat dissipation effect of the ventilation holes.

[0004] Therefore, a three-phase multi-position metal metering box is proposed to address the above problems. Summary of the Invention

[0005] The purpose of this application is to provide a three-phase multi-position metal metering box.

[0006] The three-phase multi-position metal metering box provided in this application adopts the following technical solution:

[0007] A three-phase multi-position metal metering box includes a metering box with a top cover fixedly connected to the top. Multiple sets of heat dissipation holes are opened on both sides of the metering box, and a dust filter is provided on one side of each heat dissipation hole. The metering box has a heat dissipation mechanism for heat dissipation, a dehumidification mechanism for dehumidification, and a cleaning mechanism for cleaning the dust filter. The cleaning mechanism includes a sliding groove, a drive motor, a threaded rod, a slider, a brush, a connecting frame, a connecting slot, a collection box, and a second handle. Sliding grooves are opened on both sides of the metering box. A drive motor is provided at one end of the inner wall of each sliding groove. A threaded rod is fixedly connected to one end of the drive motor. A slider is threadedly connected to the surface of the threaded rod, and a brush is fixedly connected to the surface of the slider.

[0008] Preferably, a connecting frame is fixedly connected to both sides of the inside of the metering box, a connecting groove is provided between the connecting frame and the metering box, a collection box is slidably connected to the inner wall of the connecting groove, and a second handle is fixedly connected to one end of the collection box.

[0009] By adopting the above technical solution, the collection box can be removed from the connecting groove using the second handle. When the dust, lint, and small insects adsorbed on the surface of the dust filter are cleaned off, these dust, lint, and small insects will fall into the collection box for subsequent unified treatment.

[0010] Preferably, the heat dissipation mechanism includes a fixed frame, a fixed sleeve, fins, a heat pipe, a fan, and an air outlet. The fixed frame is fixedly connected to one side of the inside of the metering box, and the fixed sleeve is slidably connected to the surface of the fixed frame. Multiple sets of fins are provided on one side of the fixed sleeve.

[0011] Preferably, the fins are equipped with heat pipes inside, the mounting bracket is connected to a fan via a motor inside, and an air outlet is provided on one side of the metering box.

[0012] By adopting the above technical solution, starting the motor can drive the fan to rotate, so that the heat inside the metering box can be discharged through the air outlet.

[0013] Preferably, the dehumidification mechanism includes a fixed plate, a vent plate, a groove, a spring groove, a spring, a locking pin, a storage box, a locking pin groove, an adsorption plate, and a first handle. The fixed plate is fixedly connected to one side of the metering box, and the vent plate is fixedly connected to the surface of the fixed plate. A groove is formed between the fixed plate and the vent plate. A spring groove is formed at one end of the inner wall of the groove. A spring is provided inside the spring groove, and a locking pin is fixedly connected to one end of the spring.

[0014] Preferably, a storage box is slidably connected to the inner wall of the groove, and a locking groove is provided at one end of the storage box. The locking groove cooperates with the locking pin. Multiple sets of adsorption plates are provided inside the storage box. The adsorption plates are color-changing silicone adsorption plates. A first handle is fixedly connected to one side of the storage box.

[0015] By adopting the above technical solution, multiple sets of adsorption plates are installed in the storage box, and then the storage box is inserted into the groove. The surface of the storage box will compress the spring and the locking pin. When the storage box is in the correct position, the spring returns and pushes the locking pin into the locking pin groove, so that the storage box can be locked on the fixed plate and the storage box will not be pulled open at will. The internal adsorption plates can adsorb the moisture in the metering box, preventing condensation on the terminal block or meter, and avoiding short circuits and corrosion.

[0016] Preferably, the spring groove is provided with a cylindrical receiving cavity that mates with the outer circumferential surface of the spring, and a radial fitting clearance is formed between the inner wall of the receiving cavity and the outer wall of the spring, the size of which is 0.08-0.25 mm.

[0017] Preferably, protective covers are rotatably connected to both sides of the metering box, and the surface of the protective covers is provided with a fixing lock.

[0018] Preferably, the bottom of one side of the top cover has multiple sets of heat dissipation vents, a copper busbar is fixedly connected to one end of the metering box, multiple sets of three-phase circuit breakers are fixedly connected to the surface of the copper busbar, and two sets of energy meter mounting brackets are fixedly connected to one end of the metering box.

[0019] Preferably, the metering box has a terminal block inside one end and a grounding copper braided strip at the bottom of the metering box inside one end.

[0020] The technical effects and advantages of this application are as follows:

[0021] Compared with existing technologies, this three-phase multi-position metal metering box uses a dehumidification mechanism to install multiple sets of adsorption plates in the storage box. The storage box is then inserted into a groove, and the surface of the storage box compresses the spring and locking pin. When the storage box is in the correct position, the spring returns to its original position and pushes the locking pin into the locking pin groove, so that the storage box can be locked onto the fixing plate and will not be pulled open arbitrarily. The internal adsorption plates can adsorb the moisture in the metering box, preventing condensation on the terminal block or meter, and avoiding short circuits and corrosion.

[0022] Compared with existing technologies, this three-phase multi-position metal metering box, through a cleaning mechanism, can rotate a threaded rod when the dust filter becomes clogged. The threaded rod has a slider connected to its surface, and a brush is fixedly connected to the surface of the slider. When the threaded rod rotates, the slider can move up and down on it, which can drive the brush to move. The movement of the brush can clean the surface of the dust filter, so as to remove the dust, lint, and small insects adsorbed on the surface of the dust filter, thereby preventing the dust filter from becoming clogged and affecting the heat dissipation effect of the heat dissipation holes.

A slider 904 is threadedly connected to the surface of the threaded rod 903. A brush 905 is fixedly connected to the surface of the slider 904. When the threaded rod 903 rotates, the slider 904 can move up and down on it, causing the brush 905 to move. The movement of the brush 905 cleans the surface of the dust filter 8, removing dust, lint, and small insects adsorbed on the surface of the dust filter 8.

[0037] In a preferred embodiment, connecting frames 906 are fixedly connected to both sides of the inside of the metering box 1.

A second handle 909 is fixedly connected to one end of the collection box 908. The collection box 908 can be removed from the connecting groove 907 by using the second handle 909. When the dust, lint, and small insects adsorbed on the surface of the dust filter 8 are cleaned off, these dust, lint, and small insects will fall into the collection box 908 for subsequent unified processing.

[0038] In a preferred embodiment, the heat dissipation mechanism 5 includes a fixed frame 501, a fixed sleeve 502, fins 503, a heat pipe 504, a fan 505, and an air outlet 506. The fixed frame 501 is fixedly connected to one side of the inside of the metering box 1, and the fixed sleeve 502 is slidably connected to the surface of the fixed frame 501. Multiple sets of fins 503 are provided on one side of the fixed sleeve 502.

[0039] In a preferred embodiment, the fin 503 is provided with a heat pipe 504 inside, which is used to transfer the heat in the heat pipe 504 to the fin 503, so that the fin 503 can rotate better.

A groove 703 is provided between the fixed plate 701 and the breathable plate 702. A spring groove 704 is provided at one end of the inner wall of the groove 703. A spring 705 is provided inside the spring groove 704. A locking pin 706 is fixedly connected to one end of the spring 705.

[0041] In a preferred embodiment, a storage box 707 is slidably connected to the inner wall of the groove 703. One end of the storage box 707 has a locking groove 708 that engages with a locking pin 706. The storage box 707 contains multiple sets of adsorption plates 709, which are color-changing silica gel adsorption plates. The color-changing silica gel (blue when dry and pink when saturated with moisture) is encapsulated in a breathable porous plastic plate or fiber bag to form a plate shape, facilitating the adsorption of moisture from the metering box 1. A first handle 710 is fixedly connected to one side of the storage box 707. Multiple sets of adsorption plates 709 are installed in the storage box 707, and then the storage box 707 is inserted into the groove 703. The surface of the storage box 707 will compress the spring 705 and the locking pin 706. When the storage box 707 is in the correct position, the spring 705 returns to its original position and pushes the locking pin 706 into the locking pin groove 708, so that the storage box 707 can be locked on the fixing plate 701, so that the storage box 707 will not be pulled open at will. The internal adsorption plates 709 can adsorb the moisture in the metering box 1, preventing condensation on the terminal block or meter, and avoiding short circuits and corrosion.

[0042] In a preferred embodiment, the spring groove 704 is provided with a cylindrical receiving cavity that mates with the outer circumferential surface of the spring 705. A radial fitting clearance is formed between the inner wall of the receiving cavity and the outer wall of the spring 705. The size range of the radial fitting clearance is 0.08-0.25mm. When the spring 705 extends or retracts, the spring groove 704 will limit the spring 705 to prevent the spring 705 from shaking.

[0043] In a preferred embodiment, protective covers 3 are rotatably connected to both sides of the surface of the metering box 1 to protect the metering box 1. The surface of the protective cover 3 is provided with a fixing lock 4, which allows the protective cover 3 to be fixed to the metering box 1.

[0044] As a preferred embodiment, multiple sets of heat dissipation vents 10 are provided on one side of the bottom of the top cover 2 to ensure air circulation and to a certain extent prevent rainwater and dust from directly entering the box. A copper busbar 11 is fixedly connected to one end of the metering box 1 for fixing the three-phase circuit breaker 12. Multiple sets of three-phase circuit breakers 12 are fixedly connected to the surface of the copper busbar 11 to switch the circuit and protect the electrical safety. Two sets of energy meter mounting brackets 13 are fixedly connected to one end of the metering box 1 so that the three-phase energy meter can be installed on the energy meter mounting bracket 13.

[0045] As a preferred embodiment, the metering box 1 has a terminal block 14 at one end of its interior to standardize wire connections and facilitate wire branching, and a grounding copper braided strip 15 at the bottom of one end of its interior to ensure the grounding safety of the box.

[0046] The working process of this application is as follows: Multiple sets of adsorption plates 709 are installed in the storage box 707, and then the storage box 707 is inserted into the groove 703. The surface of the storage box 707 will compress the spring 705 and the locking pin 706. When the storage box 707 is in the correct position, the spring 705 returns to its original position and pushes the locking pin 706 into the locking pin groove 708, so that the storage box 707 can be locked on the fixing plate 701, preventing the storage box 707 from being pulled open arbitrarily. The internal adsorption plates 709 can adsorb the moisture in the metering box 1, preventing condensation on the terminal block or meter, avoiding short circuits and corrosion. When it is necessary to dissipate heat inside the metering box 1, the motor can be started to drive the fan 505 to rotate, so as to dissipate the heat inside the metering box 1. The dust is discharged through the air outlet 506. When the dust filter 8 becomes clogged, the drive motor 902 is started, which drives the threaded rod 903 to rotate. The surface of the threaded rod 903 is threadedly connected to the slider 904, and the surface of the slider 904 is fixedly connected to the brush 905. When the threaded rod 903 rotates, the slider 904 can move up and down on it, which can drive the brush 905 to move. The movement of the brush 905 can clean the surface of the dust filter 8, so as to remove the dust, lint, and small insects adsorbed on the surface of the dust filter 8. The cleaned dust, lint, and small insects will fall into the collection box 908 for subsequent unified treatment. The above is the working principle of this three-phase multi-position metal metering box.
