Description

Technical Field

[0001] This article belongs to the technical field of medium and high voltage electrical cabinets, and specifically relates to an intelligent medium voltage switch cabinet structure with a dust removal mechanism. Background Art

[0002] High-voltage electrical cabinets are devices that open and close, control and protect electricity during the process of power generation, transmission, distribution and energy conversion in the power system. They are suitable for power plants, substations, petrochemicals, metallurgy and steel rolling, light industry and textiles, factories and mines, residential areas, hospitals, schools and other occasions.

[0003] In order to ensure that the heat generated inside the existing electrical cabinet during use is effectively dissipated, a suction fan is usually installed inside the electrical cabinet to achieve air circulation inside the electrical cabinet, allowing external air to enter to achieve convection cooling effect. A fixed convex heat dissipation port is provided at the opening of the air duct. Most of these heat dissipation ports are integrally stamped strip ports, and a through groove is provided horizontally downward at the bottom of the heat dissipation port, so that the inside and outside of the electrical cabinet can be conductively convexed while preventing foreign matter or water droplets from entering the interior of the electrical cabinet along the cabinet wall.

[0004] Usually, a suction fan is used for internal heat dissipation. Due to the strong suction force of the fan itself, the air is discharged directly and efficiently from the inside of the electrical cabinet in a straight line. In addition, the filter component of the fan itself can also filter dust.

[0005] However, during the transportation and installation of the electrical cabinet, after the cabinet arrives at the site, due to the influence of the on-site construction environment, incomplete supporting facilities, grinding of the ground and other factors, the on-site dust is particularly large, or during the static placement process, there will be floating dust in the indoor air. These dusts will enter the inner side of the openings along the openings of the heat dissipation ports and accumulate. In addition, due to the instantaneous start-up of the fan inside the electrical cabinet, the dust accumulated near the heat dissipation ports will be completely dispersed in every corner of the electrical cabinet, making it very easy for dust to accumulate in the components inside the electrical cabinet where the air duct is not easy to pass. Utility Model Content

[0006] In order to solve the above problems, this paper proposes an intelligent medium-voltage switch cabinet structure with a dust removal mechanism, wherein air inlets are arranged on both sides of the bottom of the cabinet body of the electrical cabinet, and an air outlet is arranged on the right side of the top surface of the cabinet body, and shutters are arranged on the outside of the air inlet and the air outlet, and the shutters include inlet shutters and outlet shutters, and the shutters are axially flipping shutters, and a page-turning main shaft is arranged on the inner side of the shutters, and the page-turning main shaft is connected to the valve assembly through a linkage shaft assembly, and the linkage shaft assembly includes a transmission shaft, an inlet blade shaft, an outlet blade shaft and linkage bevel teeth, and the inlet blade shaft and the outlet blade shaft are respectively connected to the flipping assemblies of the inlet shutter and the outlet shutter, and the middle part of the inlet blade shaft is connected to the transmission shaft and the outlet blade shaft through linkage bevel teeth, and the bottom end of the outlet blade shaft is provided with symmetrical bevel teeth The linkage helical teeth include symmetrical helical teeth and transmission helical teeth. The bottom end of the transmission shaft is provided with symmetrical helical teeth, and the outer side of the upper end of the transmission shaft is provided with a changing rotation tooth. The changing rotation tooth is connected to the valve assembly through a spur gear, and the rotation mechanism on the valve assembly originally provided inside the electrical cabinet is used to drive the rotation of the linkage shaft assembly, thereby realizing the linkage switch of the valve assembly and the shutters on the surface of the electrical cabinet. When the valve is opened and the electrical cabinet starts to conduct electricity, the shutters will also be opened at the same time to realize efficient wind speed flow and heat dissipation inside the electrical cabinet. When the valve is closed and the electrical cabinet is disconnected, the shutters are also closed together to prevent dust from entering the interior of the electrical cabinet, thereby preventing dust from entering and accumulating in the air outlet when the electrical cabinet is not in use. This can effectively prevent the accumulated dust from being sucked into the fan and dispersing into the interior of the electrical cabinet.

[0007] The electrical cabinet is a vertical electrical cabinet structure, with a wiring guide arranged in the middle of the inner side of the electrical cabinet, a fan arranged on the inner side of the bottom of the electrical cabinet, an outlet shutter arranged on the right side of the top surface of the electrical cabinet, and an exhaust fan arranged on the left side of the top surface of the electrical cabinet. A valve assembly is vertically partitioned in the middle of the wiring guide, inlet shutters are arranged on the surface of the electrical cabinet on both sides of the fan, and a filter assembly is arranged on the outside of the exhaust fan. By replacing the originally fixed ventilation blades on the surface of the electrical cabinet with an openable shutter structure, automatic ventilation and opening and closing of the electrical cabinet is achieved, and an exhaust fan is also auxiliaryly arranged to perform auxiliary heat dissipation inside.

[0008] The valve assembly includes a valve plate and a valve connecting rod. The valve plate is vertically arranged in the middle of the electrical cabinet. The two sides of the valve plate are axially connected to the valve connecting rod. The valve connecting rod is a crank rocker mechanism. An output shaft is provided at the center of the end of the valve connecting rod. The output shaft is connected to the valve plate through a rocker. A spur gear is provided on the outer side of the end of the output shaft. By arranging a spur gear on the output shaft of the existing valve assembly, the opening and closing of the shutters can be achieved through linkage during the operation of the valve assembly.

[0009] Both the inlet shutters and the outlet shutters are flip-up shutters, and the shutters are provided with a plurality of blades in parallel, and a rotating shaft is provided on the upper sides of both ends of the blades, and the outer edges of the blades are provided with sealing strips, and the inner sides of the plurality of blades are interconnected by a flipping assembly, and the flipping assembly is a crank-connecting rod mechanism, and the connecting rod of the flipping assembly is connected to the inner side of the blade, and the crank shaft of the flipping longitudinal axis is connected to the linkage rotating shaft assembly. Both the inlet shutters and the outlet shutters realize the outward and inward opening and closing movement of the blades through the flipping assembly, and the flipping assembly realizes the movement of the connecting rod of the rotating cover plate of the linkage rotating shaft assembly through the structure of the crank-connecting rod mechanism to realize opening and closing.

[0010] The shape of the transmission shaft is cylindrical, and the outer surface of the upper end of the transmission shaft is provided with a direction-changing rotating tooth, and the bottom end of the transmission shaft is horizontally provided with a symmetrical bevel tooth. The direction-changing rotating tooth is a vertically changing spiral tooth, and the symmetrical bevel tooth is a high-strength upper and lower symmetrical bevel tooth. The upper and lower bevel teeth of the symmetrical bevel teeth are connected by a shaft rod, and both sides of the symmetrical bevel teeth are connected to the transmission bevel teeth. By using the transmission shaft, the original horizontal rotation of the output shaft is changed into a vertical rotation, thereby realizing the rotation of the transmission shaft, and the transmission shaft realizes the linked rotation of the inlet blade shaft through the symmetrical bevel teeth.

[0011] The transmission bevel teeth are all connected to the middle end face of the inlet blade shaft. The shape of the inlet blade shaft is cylindrical. The inlet blade shaft is a horizontal double-end transmission shaft. The two ends of the inlet blade shaft are respectively connected to the flip assemblies in the shutters on both sides of the electrical cabinet. Two groups of fractures are provided in the middle of the inlet blade shaft. The end faces of the fractures are symmetrically provided with transmission bevel teeth, and symmetrical bevel teeth are provided between the symmetrical transmission bevel teeth. The first-level rotation transmission is realized through the inlet blade shaft, and its rotation can be transmitted to the inlet shutter, and the power transmission to the secondary outlet blade shaft can be realized, driving the outlet blade shaft, and the linkage bevel teeth can stably transmit the rotation of the transmission shaft alternately.

[0012] The shape of the outlet blade shaft is cylindrical, and the outlet blade shaft is a vertical shaft. The top end of the outlet blade shaft is connected to the flip assembly of the outlet shutter, and the bottom end of the outlet blade shaft is provided with symmetrical bevel teeth.

The outlet shutter is opened and closed through the outlet blade shaft, and the linkage bevel teeth can stably transmit the rotation of the inlet blade shaft alternately.

[0013] Beneficial effects:

When the valve is closed and the electrical cabinet is disconnected, the shutters will also be closed together to prevent dust from entering the interior of the electrical cabinet, thereby realizing intelligent and automated dust prevention and removal inside the cabinet.

[0015] By replacing the originally fixed ventilation louvers on the surface of the electrical cabinet with an openable shutter structure, automatic ventilation and opening and closing of the electrical cabinet is achieved, and an exhaust fan is also provided to assist in internal heat dissipation.

[0016] The inlet shutter and the outlet shutter both realize the outward and inward opening and closing movement of the blades through the flip assembly, and the flip assembly realizes the movement of the connecting rod of the rotating cover plate of the linkage shaft assembly through the structure of the crank connecting rod mechanism to realize opening and closing.

[0017] By arranging a spur gear on the output shaft of the existing valve assembly, the shutter can be driven to open and close in linkage during the operation of the valve assembly.
