[0002] Wind power refers to a renewable energy technology that uses wind energy to generate electricity. The classification of wind power technology mainly includes horizontal axis wind turbines, vertical axis wind turbines, direct drive wind turbines and doubly fed wind turbines. Offshore wind power refers to wind farms built in offshore areas with a water depth of about 10 meters. Since offshore wind power is located in the offshore area, the environmental humidity is always at a high level, and the seawater is corrosive, which will cause corrosion to the outer shell and seals at some joints. Therefore, the waterproof requirements of its units are higher than those of land wind power.

[0036] The front side of the waterproof sticker is provided with grooves on the left and right sides near the concave area, and power strips are installed in the grooves. The power strips at the corresponding positions on the left and right sides are electrically connected to the detection piece through connecting pieces, and the power strips on the left and right sides of the concave area are electrically connected to the repeater through wires.

[0037] The top surfaces of the waterproof stickers on the left and right sides of the concave area are provided with fixed areas, and the thickness of the waterproof stickers in the fixed areas is lower than that of the waterproof stickers in the concave area.

[0038] A cover plate is provided on the top surface of the waterproof sticker at a position corresponding to the opening of the groove, a shift strip is installed on one side of the cover plate, and the other side of the cover plate is fixed to the waterproof sticker at the corresponding position.

[0039] The front side of the waterproof sticker is provided with grooves at the left and right sides near the concave area, and a plurality of power connection plates are installed in the grooves corresponding to the connection plate positions, and the plurality of power connection plates are electrically connected to the repeater through a plurality of wires.

[0040] Embodiment 1

[0041] The technical solutions in the embodiments of the present application are clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0042] like Figure 1-6As shown, an offshore wind turbine water seepage detection device includes a waterproof sticker arranged at the joint position of the electromechanical compartment and the wind wheel cover, a concave area is preset on the rear side of the waterproof sticker, and a plurality of detection pieces, namely the above-mentioned water seepage conductive sensing pieces, are glued and installed on the inner wall of the concave area. The cross-section of the detection piece is U-shaped, and the detection piece is made of aluminum. The plurality of detection pieces are staggered on the left and right sides of the concave area. Grooves are preset on the left and right sides of the front side of the waterproof sticker near the concave area, and power connection strips are glued and installed in the grooves. The power connection strips at corresponding positions on the left and right sides of the concave area are electrically connected to the detection pieces through connecting pieces, and the two ends of the connecting piece are welded and fixed to the power connection strips and the detection pieces at corresponding positions.

[0043] The top surfaces of the waterproof strips on the left and right sides of the concave area are preset with fixed areas, and the thickness of the waterproof strips in the fixed areas is lower than that of the waterproof strips in the concave area. The power strips on the left and right sides of the concave area are respectively electrically connected to the repeater through wires, and the repeater is connected to the receiving host electrical signal through a wireless communication module. The repeater is installed on the electromechanical warehouse or the inner wall of the wind wheel cover close to the waterproof strips, and the receiving host is installed in the wind turbine controller and is connected to the power generation monitoring center electrical signal by wire.

[0044] When in use, the waterproof sticker is attached to the adjacent shell connection gap position inside the wind turbine through adhesive, such as the connection gap position between the electromechanical compartment and the wind wheel cover. First, measure the gap length, cut the waterproof sticker of the required length, brush the adhesive on the fixed area position on the top surface of the waterproof sticker, and then stick it on the electromechanical compartment and the inner wall of the wind wheel cover on both sides of the gap to solidify and fix it, then install the repeater and the receiving host, and then use the wire to electrically connect the connection strip to the repeater. When there is water seepage at the gap position, the waterproof sticker will first restrain the water that penetrates into the interior, so that it will be retained in the concave area as much as possible, reducing or delaying its spread inside the wind turbine. When water reaches the detection pieces on the left and right sides of the concave area at the same time, the water acts as a conductor to connect the detection pieces on both sides, so that the circuit of the repeater is connected, and the repeater sends a signal. When the signal is received by the receiving host, it means that water seepage has occurred. The repeaters installed at different positions in the wind turbine are numbered, and the location of the water seepage can be quickly confirmed according to the source of the received signal, so as to facilitate the subsequent arrangement of maintenance.

[0045] In this embodiment, a cover plate is provided on the top surface of the waterproof strip at the position corresponding to the groove mouth. The cover plate is made of rubber material. A shift strip is integrally installed on one side of the cover plate. The other side of the cover plate away from the shift strip is hot-melt welded to the waterproof strip at the corresponding position.

[0046] When connecting the wires, first open the cover from the pull-bar position, then weld and fix the wires. After the wires are fixed, put the cover back on to form insulation protection for the connecting wires.

[0047] In this embodiment, the connection bar is replaced by a connection plate, which is no longer a connection plate connecting all the connection plates on one side of the recessed area.

[0048] A plurality of electrical connection sheets are glued and installed in the groove at positions corresponding to the connection sheets, and the plurality of electrical connection sheets are electrically connected to the repeater through a plurality of wires.

[0049] As the number of terminal strips increases, multiple repeaters can be set up in one place according to the number of interfaces of the repeater. Each terminal strip can be numbered individually. In this way, when there is a water seepage signal, the source of the initial water seepage signal can be checked, and the initial water seepage location can be confirmed according to the number information, so there is no need to remove the entire waterproof sticker for searching.
