Description

Technical Field

[0001] The present invention relates to the technical field of cable connection equipment, and in particular to a distributed photovoltaic consumption cable connection equipment. Background Art

[0002] Photovoltaic absorption cables play a vital role in the photovoltaic absorption process. Photovoltaic absorption means effectively matching the electric energy generated by photovoltaic power generation with the load of the power system, so as to match the load of the power network to the output of photovoltaic power generation as much as possible. In this process, photovoltaic cables are responsible for transmitting the electric energy generated by solar panels, ensuring that the electric energy can be safely and efficiently connected to the power system to meet the load requirements of the power system.

[0003] When the existing distributed photovoltaic power generation grid-connected box is used, the heat dissipation holes opened on the grid-connected box are generally fixed in size and cannot be adjusted accordingly according to the temperature changes in the grid-connected box. Therefore, the heat dissipation speed in the grid-connected box is slow, and the temperature inside the box is easily too high, which may cause the components inside to overheat and be damaged. Based on these problems, Chinese patent CN219018252U discloses a distributed photovoltaic power generation grid-connected box. By setting an adjustment component and an exhaust component at the top of the grid-connected box, the temperature detection module in the grid-connected box can detect the temperature. When the temperature is normal, the square mesh plate will be stored in the square groove, and the fan will rotate at a low speed to discharge air into the grid-connected box and discharge it through the exhaust holes. , to achieve heat dissipation in the grid-connected box. When the temperature in the grid-connected box is too high, the control panel controls the two electric push rods to push the two supporting slide bars up, thereby pushing the top plate up, so that the top of the grid-connected box can be opened, and the rising of the top plate can drive the square mesh plate to slide up from the square groove, and then the open part can be isolated by the square mesh plate to prevent foreign matter from entering. At this time, the high rotation of the fan can speed up the speed at which air flows into the grid-connected box, and then it is discharged through the open part at the top of the grid-connected box, thereby speeding up the flow of air in the grid-connected box and increasing the speed of cooling the grid-connected box, thereby making corresponding adjustments to the heat dissipation speed according to the temperature, and ensuring the normal operation of the electrical components in the grid-connected box.

[0004] The grid-connected box uses an electric push rod to push the top plate up, so that the top of the grid-connected box is open, and then the fan is used to supply air from the bottom to the inside of the grid-connected box, accelerating air circulation while achieving cooling and heat dissipation effects. Since the grid-connected box lacks a structure to fix and protect the cables, the cables are easily loosened or fall off under the external force of gas flow, seriously affecting the safety of the connection between the distributed photovoltaic power generation system and the power grid.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) An opening is provided at the bottom of the protective shell, and the cable is inserted from the bottom of the protective shell. The moving direction of the cable can be guided by setting a guide roller. The outer wall of the balloon is provided at the wide part of the internal space of the cavity. The outer wall of the cable can be inserted from the narrow part at the bottom of the cavity, pass through the inner wall of the balloon, and then extend from the narrow part at the top of the cavity. The air can be inflated into the inside of the balloon by using a vent pipe. When the balloon expands, the cross-sectional size of the inner wall of the balloon gradually decreases, which can not only clamp the cable, but also protect the outer wall of the cable. First, place the part of the cable where wiring is completed on the rubber pad on the concave surface of the arc-shaped clamping plate in the clamping block at the top of the pad, and then tighten the first threaded rod. When rotating, the rotating first threaded rod can move up and down on the inner wall of the threaded sleeve. When the first threaded rod moves downward, the clamping block at the bottom of the shaft will also move downward. At this time, the clamping block at the bottom of the shaft will slowly approach the clamping block on the top of the pad. When the first threaded rod drops to a certain height, the rubber pad on the concave surface of the arc-shaped clamping plate on the clamping block at the bottom of the shaft will be tightly attached to the outer wall of the cable. At this time, continue to rotate the first threaded rod to fix the cable. Through this structure, not only can the cable be fixed again, but also the requirements for fixing cables of different sizes are met, which is beneficial to improving the safety of the connection between the distributed photovoltaic power generation system and the power grid.

[0026] (2) A cavity is opened in the hollow placement plate, which runs through from top to bottom. The limit plates are arranged on both sides of the cavity opening on the top surface of the hollow placement plate. The width of the wiring device is smaller than the cross-sectional width of the cavity inside the hollow placement plate. When the fan blows air upward, the gas will pass through the other two ends of the cavity inside the hollow placement plate. At this time, the wiring device can be cooled. The cable passing through the entry frame needs to pass through the frame before it can be connected to the wiring device. The frames are arranged on both sides of the wiring device. The cooling gas passing through the other two ends of the cavity inside the hollow placement plate cannot directly contact the connection area between the cable and the wiring device, thereby reducing the influence of external force on the cable.

[0027] (3) By setting up the filter plate, honeycomb activated carbon and filter body, the air about to enter the equipment can be filtered, thereby separating the dust, lint or water vapor in the air. By setting up a simple connection method between the filter plate and the outer cylinder, the disassembly and assembly steps of the outer cylinder are made more convenient and quick, and it is also convenient to replace the honeycomb activated carbon in the outer cylinder.

[0028] (4) The opposite surface of the scraper rod is in close contact with the outer wall of the dustproof ventilation mesh cover. When the motor drives the turntable to rotate, the scraper rod will slide along the outer wall of the dustproof ventilation mesh cover, thereby directly removing the dust or lint attached to the surface of the dustproof ventilation mesh cover, which is conducive to the orderly discharge of heat.

[0029] (5) When the smoke sensor detects thick smoke or flames, the control module will immediately start the water pump, which will then use the delivery pipe to pump water out of the water tank and deliver the water to the square pipe in a timely manner. The water will then be quickly sprayed out from the nozzle to eliminate the thick smoke and flames, which not only reduces the loss of cable-connected equipment but also improves the safety of the entire equipment.

By setting a simple connection method between the filter plate 9 and the outer cylinder 10, the disassembly and assembly steps of the outer cylinder 10 are more convenient and quick, and it is also convenient to replace the honeycomb activated carbon 11 in the outer cylinder 10.

[0047] The bottom ends of both sides of the inner wall of the bottom box 1 are fixedly connected with support plates 13, and the top of the support plate 13 is fixedly connected with multiple sets of hollow placement plates 14. A cavity running through the top and bottom is opened in the hollow placement plate 14. Limit plates 15 are welded at both ends of the top of the hollow placement plate 14.
