Description

Technical Field

[0002] Wind energy refers to the energy generated during the flow of wind, which is renewable. Wind power generation converts wind energy into electrical energy using specific power generation devices. Compared with other power generation methods, wind power generation does not emit greenhouse gases during the power generation process, making wind power generation gradually become a new option to replace fossil fuel power generation. Wind power generation devices mainly include a wind blade mechanism and a transmission mechanism with multiple blades and a power generation device. Among them, wind blades are an indispensable structure in the wind power generation process. In the process of producing wind power blades, in order to ensure the stable and long-term use of wind power blades, it is necessary to inspect the wind power blades after production. Therefore, a wind turbine blade inspection device is needed to complete the inspection work.

[0003] However, the existing wind turbine blade detection device still has certain defects when used;

[0004] For example, a method and device for detecting surface defects of wind turbine blades proposed in the application number CN201611132285.X. The method for detecting surface defects of wind turbine blades includes the following steps: obtaining a preset pressure difference value; setting a standard pressure value of a pressure detection module; placing the pressure detection module in the area to be detected on the surface of the blade, moving the pressure detection module along a set trajectory on the surface of the area to be detected, and the pressure detection module detecting the real-time pressure value of the surface of the area to be detected in real time; calculating the pressure difference between the real-time pressure value and the standard pressure value; comparing the pressure difference with the preset pressure difference value to determine the type of surface defect of the blade; marking the type of surface defect of the blade. This detection method has low cost, simple operation, accurate and fast detection, and avoids the time-consuming surface defect detection of blades, which reduces the production of wind turbine blades. In actual use, the following problems still exist:

[0005] During the use of the wind turbine blade surface defect detection device, surface defects are detected and marked by testing the pressure difference. After the wind turbine blades are produced, a large amount of dust and dirt will adhere to the surface, and these adhered dust and dirt will affect the accuracy of pressure difference detection, thereby reducing the detection effect of the existing wind turbine blade surface defect detection device.

[0049] The above description enables the connection and separation of the lower fastener 304 and the upper fastener 306 to be realized by controlling the connection and separation between the fixing nut 307 and the connecting column 305. When the two are separated, the wind turbine blade body 4 can be easily installed and disassembled, and when the two are connected, the wind turbine blade body 4 can be positioned and fixed, wherein the support rod 303 can stably connect the slide 301 and the lower fastener 304. At this time, the control lifting cylinder 9 can drive the connecting plate 10 and the ultrasonic detection head 12 and the components installed on the connecting plate 10 to descend until the ultrasonic detection head 12 reaches a suitable detection position;

[0050] When the servo motor 8 is started to drive the first screw rod 6 to rotate, the first screw rod 6 will drive the base 5 and the corresponding pressing mechanism 3 to move. When the wind turbine blade body 4 is inspected, the movement of the pressing mechanism 3 will drive the wind turbine blade body 4 to slowly pass through the bottom of the ultrasonic detection head 12, so that the ultrasonic detection head 12 can detect defects in the wind turbine blade body 4.

[0051] A flushing power mechanism 17 is symmetrically installed on the top of one end of the fixed bottom plate 1. The flushing power mechanism 17 includes a sealing box 1701 symmetrically fixedly installed on the top surface of the fixed bottom plate 1. A fixed shaft 1702 is inlaid at the bottom of the sealing box 1701. A second screw rod 1703 runs through the interior of the fixed shaft 1702. A piston plate 1704 is sleeved on the second screw rod 1703. The second screw rod 1703 forms a screw transmission structure with the sealing box 1701 through the piston plate 1704. The second screw rod 1703 is rotatably connected with the fixed bottom plate 1. A transmission gear 1705 is fixedly installed on the bottom end of the second screw rod 1703. A one-way water inlet pipe 1706 is installed on the top of the sealing box 1701. A one-way water outlet pipe 1707 is installed on one side of the top, the sealing box 1701 is connected to the flushing nozzle 1304, and a relief valve 1708 and an air extraction valve 1709 are vertically installed at the bottom of the sealing box 1701. The air extraction valve 1709 is connected to the negative pressure pipe 1605. A transmission rack 18 is attached to one side of the transmission gear 1705, and the bottom end of the second screw rod 1703 forms a meshing transmission structure with the transmission rack 18 through the transmission gear 1705. A second connecting seat 19 is fixedly installed at one end of the transmission rack 18, and the second connecting seat 19 is fixedly connected to the bottom of one group of buckling mechanisms 3. A limiting groove 20 is symmetrically provided inside one end of the fixed bottom plate 1, and the limiting groove 20 is slidably connected to the second connecting seat 19;

[0052] The above records make the buckling mechanism 3 drive the second connecting seat 19 to slide inside the limiting groove 20 during the process of driving the wind turbine blade body 4 to move and detect, and drive the transmission rack 18 to move synchronously. At this time, the transmission rack 18 will drive the transmission gear 1705 that is meshed on one side, so that the transmission gear 1705 drives the second screw rod 1703 to cooperate with the second screw rod 1703 to rotate inside the sealing box 1701. During the movement detection of the wind turbine blade body 4, the second screw rod 1703 will be driven to rotate forward and drive the piston plate 1704 to rise. During the resetting process of the buckling mechanism 3, the second screw rod 1703 will rotate in the opposite direction and drive the piston plate 1704 to descend. When the piston plate 1704 descends, it can be deflated through the deflation valve 1708, and the external water can be extracted through the one-way water inlet pipe 1706 and stored in the sealing box 1701.

[0053] A sliding flushing mechanism 13 is installed on one side of the connecting plate 10, and the sliding flushing mechanism 13 includes a limit seat 1301 symmetrically fixedly installed on one side of the connecting plate 10, a movable seat 1302 is slidably connected to the limit seat 1301, one end of the movable seat 1302 is fixedly connected to a mounting plate 1303, the mounting plate 1303 is limitedly slidably connected to the limit seat 1301 through the movable seat 1302, a flushing nozzle 1304 is installed inside the mounting plate 1303, and the flushing nozzle 1304 is installed at equal intervals inside the mounting plate 1303, a first connecting seat 1305 is fixedly installed on one side of the mounting plate 1303, a contact rod 1306 is fixedly installed on the top of the first connecting seat 1305, the contact rod 1306 is slidably connected to the connecting plate 10, the contact rod 1306 is arranged in a "U"-shaped structure, and when the piston plate 1704 rises, the one-way water outlet pipe 1707 cooperates with the flushing nozzle 1304 to form a flushing structure;

[0054] The above records ensure that during the moving detection process, the wind turbine blade body 4 will drive the contact rod 1306 in contact with it to rise and fall synchronously, and then the contact rod 1306 will use the movable seat 1302 to drive the mounting plate 1303 and the flushing nozzle 1304 to rise and fall, maintaining a constant effective flushing distance between the flushing nozzle 1304 and the wind turbine blade body 4, wherein the sliding connection between the limit seat 1301 and the movable seat 1302 can limit the lifting and lowering of the mounting plate 1303 and the flushing nozzle 1304, and when the piston plate 1704 rises, it will squeeze the water stored in the sealing box 1701, and then the water will be sprayed out through the one-way water outlet pipe 1707 and the flushing nozzle 1304, thereby realizing the surface flushing of the wind turbine blade body 4 during the movement.

[0055] A fixed seat 14 is fixedly installed on one side of the sliding flushing mechanism 13, a dust suction head 15 is installed on one end of the fixed seat 14, and dust suction mechanisms 16 are connected to the tops of both ends of the dust suction head 15.

When the piston plate 1704 rises, the air extraction valve 1709 cooperates with the negative pressure pipe 1605 to form negative pressure inside the dust storage box 1601;

[0056] The above records enable the sliding flushing mechanism 13 to drive the dust collector head 15 to rise and fall synchronously with the wind turbine blade body 4 through the fixed seat 14, thereby ensuring a constant distance between the dust collector head 15 and the wind turbine blade body 4 for effective dust suction. When the piston plate 1704 rises, the vacuum valve 1709 will be used in conjunction with the negative pressure tube 1605 to form a negative pressure inside the dust storage box 1601. The negative pressure formed can remove dust on the surface of the wind turbine blade body 4 through the dust collection tube 1604 and the dust collection head 15 and store it in the dust storage box 1601. The setting of the filter plate 1602 can prevent dust from entering the negative pressure tube 1605 and the sealing box 1701, and the disassembly of the sealing plate 1603 can effectively clean the dust stored in the dust storage box 1601.

At this time, the ultrasonic detection head 12 can slowly detect the moving wind turbine blade body 4. In the process of movement, because the bottom end of the sliding flushing mechanism 13 is in contact with the surface of the wind turbine blade body 4, the sliding flushing mechanism 13 and the dust collection mechanism 16 always maintain a constant distance from the wind turbine blade body 4;

[0060] Step 3: When the pressing mechanism 3 drives the wind turbine blade body 4 to move, the transmission rack 18 will be driven to move synchronously through the second connecting seat 19, and then the transmission rack 18 will drive the flushing power mechanism 17 to perform an ascending piston movement, and then the dust on the surface of the wind turbine blade body 4 will be sucked out through the dust suction mechanism 16 and the dust suction head 15, and at the same time, the water stored inside will be sprayed out through the sliding flushing mechanism 13 to further clean the wind turbine blade body 4, so as to avoid the adhesion of dust and dirt affecting the detection effect of the ultrasonic detection head 12;
