[0035] like Figure 1 , Figure 3 , Figure 4 As shown, this utility model provides a drying and protection device for turbine blades, including a frame structure 1 and a protective structure 2. Multiple first squares 3 are evenly distributed on the upper surface of the frame structure 1. During drying, a turbine blade can be placed in each first square 3. The number of first squares 3 is limited by the size of the drying chamber, and the arrangement of the first squares 3 is reasonably set within the allowable size. To protect the turbine blades and prevent them from being bumped by the frame structure 1 or adjacent turbine blades, the protective structure 2 is laid on the upper surface of the frame structure 1. Simultaneously, a device grid box 7 extends from the position of the first squares 3 away from the upper surface of the frame structure 1, and both the upper and lower ends of the device grid box 7 are open. The turbine blades are confined within the device grid box 7, preventing collisions between adjacent blades.

[0036] like Figure 2 The diagram shows the structure of a turbine blade. This blade is a slender, hollow blade. Based on its shape and structural characteristics, placing the blade vertically helps the water after cleaning to slide down along the inner cavity of the blade, achieving a rapid drying effect. Therefore, in this embodiment, the lower half of the blade is located inside the device compartment 7, and the edge plate 12 is directly mounted on the upper surface of the frame structure 1, which is covered with the protective structure 2. The tenon 11 protrudes 25mm above the upper surface for easy handling by the operator.

[0037] By evenly opening a plurality of first squares 3 on the upper end surface of the frame structure 1, this arrangement not only makes each turbine blade have an independent placement position, realizes uniform placement of the blades, ensures uniform heating of the blade surface, thereby improving the drying efficiency; the setting of the device grid box 7 effectively prevents the turbine blade from colliding with the frame structure 1 or the adjacent blade during the drying process, each blade is independent of each other, which can avoid scratching the blade during work, thereby improving product quality and reliability, greatly improving the quality of the dried blade, and effectively fixing the blade to ensure the stability of the blade during the drying process; considering the slender hollow structure of the turbine blade, the drying protection device vertically places the blade, which helps the water after cleaning the blade to naturally slide along the inner cavity, thereby speeding up the drying speed.

[0038] As shown in Figure 1 In the preferred scheme, the frame structure 1 includes: a frame body 4 and a support plate 5 arranged on the upper end surface of the frame body 4, and a plurality of first squares 3 are evenly opened through the support plate 5. Specifically, the frame body 4 is formed by welding a plurality of stainless steel pipes, and the diameter of the steel pipe is φ12mm. The circular steel pipe is helpful for handheld and has no corners, which will not hurt the hand. The overall size is: 400mm*314mm*165mm, the full load parts are 20, and the total weight is not more than 10kg. The support plate 5 is made of a stainless steel plate with a thickness of 2mm, and the support plate 5 is limited by the first squares 3, and in this embodiment, there are 20 first squares 3 with the same size, and the frame body 4 below the first squares 3 is hollowly arranged to avoid affecting the vertical placement of the blade. By arranging a plurality of grids, independent placement of each blade is realized, and there is no collision between the blades, which protects the integrity of the blade; the frame body 4 is stable in structure, which improves the carrying capacity of the blade; the frame body 4 is a hollow structure, which is simple and firm, has low maintenance cost, is easy to use, and can achieve the effect of rapid drying; and the frame structure 1 is made of stainless steel. Since the protection device is immersed in water for a long time, stainless steel has good corrosion resistance and is not easy to corrode and wear. It can be envisaged that by adjusting the size and number of the first squares 3, the placement requirements of blades of different specifications can be met.

[0039] According to the size of the blade, the drying protection device is designed with a grid, and the size of a single first square 3 must be greater than the size of the blade crown of a blade, that is, the area of the first square 3 is greater than the area of the blade crown. The first square 3 is a rectangle, and the minimum size of the first square 3 must be smaller than the length of the edge plate 12, so that when the blade is placed, the edge plate 12 of the blade can be directly placed on the upper end surface of the support plate 5 at the first square 3. Therefore, in this embodiment, a single workstation plane size, that is, the size of the first square 3 is 38mm*35mm, is set to facilitate the blade to be placed while effectively improving the space utilization rate.

[0040] By setting the size of the single first grid 3 to be larger than the size of the blade crown, it is ensured that the blade can be smoothly placed into the grid, avoiding the problem of difficulty in placement or damage to the blade due to size mismatch; the minimum size of the first grid 3 is smaller than the length of the rim plate 12, so that the rim plate 12 of the blade can be directly arranged on the upper end surface of the support plate 5 at the first grid 3, enhancing the stability and convenience of placement; the size of the first grid 3 is adapted to the size of the blade, also achieving effective use of space and avoiding waste of space.

According to the characteristics of the blade, the surface of the blade is coated with a plasma coating, in order to ensure the integrity of the coating, the protection device adopts a grid design, the device grid box 7 is arranged on the lower end surface of the protection flat plate 6 and the support plate 5 corresponding to the position of the second grid 8, and the size of a single grid must be larger than the size of one blade crown, so the size of the device grid box 7 is set to 38mm*35mm*135mm. When the blade is placed in the drying protection device, the protection flat plate 6 is laid on the upper end surface of the support plate 5, the surface contacted by the blade, i.e. the upper end surface of the support plate 5, is increased by the protection flat plate 6, the blade crown 14 and part of the blade body 13 are placed in the device grid box 7, and a certain distance is left between the blades, which can avoid scratching the blades during work.

[0042] The protection structure 2 is designed by grids, and multiple grids achieve limiting effect between the blades in the horizontal direction, preventing scratching and ensuring the integrity of the surface coating of the blade; the device grid box 7 provides independent storage space for the blade, effectively avoiding direct contact between the blades, thereby protecting the integrity of the coating; when the blade is placed in the drying protection device, the protection flat plate 6 provides an additional protective layer for the blade, reducing direct contact between the blade and the support plate 5, thereby reducing the risk of scratching the surface of the blade.

[0043] As shown in Figure 1 , the two opposite sides of the second grid 8 on the protection flat plate 6 extend downward to connect the device grid box 7; in a feasible embodiment, the two wide sides of the second grid 8 extend downward to connect the device grid box 7, and the connection between the protection flat plate 6 and the device grid box 7 is more convenient and firm due to the arrangement of the connecting piece 9. It is conceivable that the connecting piece 9 can also be arranged at the positions corresponding to the two long sides of the second grid 8, which is not limited here.

[0044] In the embodiment, the protective flat plate 6, the device grid box 7 and the connecting plate 9 are all made of asbestos board, specifically, the asbestos board can be pasted on the inner side and the upper surface of the frame structure 1 by using high-temperature-resistant strong glue; the part in contact with the blade is made of asbestos board, the hardness of the asbestos board is lower than that of the blade, and the blade will not be damaged by knocking during work, so the blade can be effectively protected, and the asbestos board can withstand high temperature and high pressure and is not easy to deform.

It can be conceived that the number and size of the air holes 10 can be adaptively adjusted as needed, and are not limited to the arrangement mode in the embodiment. The air holes 10 provided on the device grid box 7 are used for rapid evaporation of moisture in the drying box.

[0046] In the embodiment, the upper and lower limits of the blade mainly rely on the protective flat plate 6 and the supporting plate 5 on the upper part of the device, the blade edge plate 12 contacts the same to achieve the limiting effect, and the blade is stably placed in the protective device. During work, the blade tenon 11 part is held by hand, the blade crown 14 and the blade body 13 part are passed through the first square 3 and the second square 8, and the edge plate 12 of the blade abuts against the upper surface of the device. After the blade is completely placed in place, the edge of the device is placed into the drying box for work.

[0047] The drying protective device realizes vertical placement of the blade, facilitates taking and placing, and realizes isolation between parts to avoid knocking. At the same time, by increasing the grid protection and limiting, the blade is prevented from tilting and falling during carrying, and less space is occupied. The drying protective device has a hollow structure, which is beneficial to ventilation of the blade, each device grid box 7 is provided with a plurality of holes with a diameter of 3mm, which helps to reduce the weight of the device and achieve rapid drying effect; through reasonable layout and design, the blade is convenient to take and place, the lower half of the blade is located in the device grid box 7, and the tenon 11 part is 25mm higher than the upper surface, which is convenient for the operator to take and place.
