Description

Technical Field

[0001] This utility model belongs to the field of cable connection technology, and in particular relates to a quick connection and fixing component for wind power plant cables. Background Technology

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source that has been utilized by humans for a long time, mainly through windmills for pumping water and grinding grain. People are interested in how to use wind to generate electricity. Wind power generation is very environmentally friendly, and wind energy reserves are enormous, therefore it is receiving increasing attention from countries around the world.

[0003] Wind power generation requires wind turbines, which are typically equipped with transformers. In the process of converting mechanical energy into electrical energy, wind turbines use transformers to regulate the voltage so that the electrical energy can be efficiently transmitted to the power grid. For example, a wind turbine typically outputs 380V, but in order to efficiently transmit the electrical energy to the grid, the voltage usually needs to be boosted to 690V.

[0004] When connecting a wind turbine to a transformer, a cable is required. The cable connection is located at a side terminal of the transformer, with a grounding post fixedly connected to the upper end of the side terminal. One end of the cable is fixedly connected to a crimping plate with a small hole at its top. The grounding post is inserted into the hole, and a nut is installed on the periphery of the grounding post. Tightening the nut secures the crimping plate. However, this connection method has the following drawbacks: although it can maintain a stable connection between the crimping plate and the grounding post, there is no protective structure around the connection. Since wind turbines are used outdoors, rainwater can erode the connection between the nut and the grounding post during rainy or snowy weather, causing unstable connections and affecting the transformer's power conversion efficiency. To solve these problems, a quick connection and fixing component for wind turbine cables is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a quick connection and fixing component for wind power plant cables, which solves the problem that although the existing cable and transformer connection methods can maintain the connection stability between the crimping plate and the terminal post, there is no protective structure around it after connection. Since wind power generation devices are used outdoors, rainwater will erode the connection position between the nut and the terminal post in rainy or snowy weather, causing unstable connection and affecting the transformer's power conversion effect.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a quick connection and fixing assembly for wind power plant cables, comprising a base, a protective box, a junction plate, and a cable body. One side of the protective box has a strip-shaped groove, within which a sealing strip is fixedly connected. A junction post is fixedly connected to the upper surface of the junction plate, and a crimping plate is installed on the periphery of the junction post. The crimping plate is fixedly connected to the cable body. A sealing ring is fixedly connected to one side of the protective box, and a sealing gasket is fixedly connected to one side of the base. The sealing gasket and the sealing ring are bonded together. A waterproof and breathable membrane is bonded to one side of the inner wall of the protective box. Several pressure rods are fixedly connected to the top surface of the inner wall of the protective box, and a pressure plate is fixedly connected to the bottom end of each pressure rod. A rubber plate is fixedly connected to the bottom surface of the pressure plate. A waterproof bonding pad is fixedly connected to the periphery of the base, and several water-retaining eaves are fixedly connected to the periphery of the protective box.

[0008] Preferably, a plurality of slots are fixedly connected to one side of the base, and a plug is installed in the slot. The plug is fixedly connected to the protective box. A threaded groove is opened on one surface of the plug and the slot, and a bolt is installed in the threaded groove.

[0009] Preferably, the crimping tab is inserted into the electrical terminal.

[0010] Preferably, the position of the pressure plate is adapted to the position of the pressing sheet, and the position of the waterproof and breathable membrane is adapted to the position of the sealing strip.

[0011] Preferably, the base is fixedly connected to the power supply board.

[0012] Preferably, the bolt is threaded into the threaded groove, and the insert is inserted into the slot.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model, by setting up a crimping plate, a protective box, a sealing ring, a sealing strip, a waterproof and breathable membrane, and a waterproof bonding pad, allows the pressure plate to push the rubber plate onto the upper surface of the crimping plate, achieving rapid fixation of the cable body connection. Then, the sealing strip is inserted into the strip groove to seal the groove. The waterproof and breathable membrane, together with the sealing strip, can effectively seal the connection position between the protective box and the junction plate. The rubber plate can increase the friction between the pressure plate and the crimping plate, making the pressing more stable. The sealing ring is bonded to the connection position between the cable body and the mounting groove to seal it. Finally, the waterproof bonding pad is bonded to the periphery of the protective box and the base to seal the contact position. Multiple seals can prevent moisture from entering the protective box and corroding the transformer's connection position, thus preventing transformer voltage instability.

[0015] 2. This utility model, by setting up a plug, a slot and a bolt, allows the plug to be inserted into the slot after the protective box is rotated and sealed, and then the bolt is tightened. This allows the bolt to be inserted into the threaded groove to fix the protective box and prevent it from loosening.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The protective box 2 is connected to the base 1, the protective box 2 is placed from above, and the sealing ring 5 is bonded to the sealing gasket 17 to further seal the installation groove position.

[0026] A strip groove is provided on one side of the protective box 2, and a sealing strip 10 is fixedly connected in the strip groove. A waterproof and breathable membrane 11 is adhered to one side of the inner wall of the protective box 2. The position of the waterproof and breathable membrane 11 is adapted to the position of the sealing strip 10 to seal the strip groove. The waterproof and breathable membrane 11, together with the sealing strip 10, can effectively seal the connection between the protective box 2 and the power board.

[0027] Several pressure rods 12 are fixedly connected to the top surface of the inner wall of the protective box 2. Pressure plates 15 are fixedly connected to the bottom ends of the pressure rods 12. Rubber plates 16 are fixedly connected to the bottom surface of the pressure plates 15.

The pressure plate 15 pushes the rubber plate 16 to press against the upper surface of the crimping plate 13, realizing quick fixing of the cable body 3. Then, the rubber plate 16 can increase the friction between the pressure plate 15 and the crimping plate 13, making the pressing more stable. The other side of the protective box 2 has an installation groove for placing the cable body 3. Then, the sealing ring 6 and the sealing gasket 17 are glued. Next, the connection between the cable body 3 and the mounting groove is sealed. The sealing strip 10 is fixed in the groove to seal the groove. The waterproof and breathable membrane 11, together with the sealing strip 10, can effectively seal the connection between the protective box 2 and the junction box. Finally, the waterproof bonding pad 4 is glued to the periphery of the protective box 2 and the base 1 to seal the contact points. The protective box 2 can block most of the external rainwater. The multiple seals can seal the contact points between the protective box 2 and the base 11, the cable body 3 and the junction box. The water-blocking eaves 6 are set at an angle and extend outward, which can keep rainwater away from the protective box 2 and prevent water vapor from entering the protective box 2 and corroding the transformer's connection points, which would lead to transformer voltage instability.
