[0024] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

[0026] The technical solution of this utility model will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

Figure 3 This is a schematic diagram of the axial limiting mechanism of this utility model. Figure 4 This is a schematic diagram of the structure of this utility model with constant ambient temperature.

[0028] A storage device for high-precision turbine blades includes a first horizontal bar 1, a second horizontal bar 2, a third horizontal bar 3, a first connecting bar 5, a second connecting bar 6, and four load-bearing supports 4. One end of the first connecting bar 5 is connected to one end of the first horizontal bar 1, and the other end is connected to one end of the second horizontal bar 2. One end of the second connecting bar 6 is connected to the remaining end of the first horizontal bar 1, and the other end is connected to the remaining end of the second horizontal bar 2. The four load-bearing supports 4 provide support for the rectangular structure formed by connecting the first horizontal bar 1, the second horizontal bar 2, the first connecting bar 5, and the second connecting bar 6. The third horizontal bar 3 is located between the first horizontal bar 1 and the second horizontal bar 2. One end of the third horizontal bar 3 is connected to the first connecting bar 5, and the other end is connected to the second connecting bar 6. Several circumferential limiting tubes 7 are provided on the third horizontal bar 3 in the transverse direction. The distance between two adjacent circumferential limiting tubes 7 is greater than the circumferential dimension of the high-precision turbine blade.

[0029] By setting the third horizontal bar 3 and the circumferential limiting tube 7, the high-precision turbine blade is placed through its shaft hole during storage. After placement, a portion of the high-precision turbine blade's disc rests on the first horizontal bar 1, and a symmetrical portion rests on the second horizontal bar 2. The circumferential limiting tube 7 restricts the lateral movement of the high-precision turbine blade, effectively preventing wear, collision, and damage to the blade portion (especially the tip) caused by axial movement, even under force majeure.

[0030] In one or more specific embodiments of this utility model, in order to minimize the lateral movement range, the outer diameter of the circumferential limiting tube 7 is matched with the shaft hole of the turbine blade.

[0031] In one or more specific embodiments of this utility model, for better limiting, an axial limiting mechanism 8 is detachably connected to the upper end of the circumferential limiting tube 7. The axial limiting mechanism 8 includes a connecting tube 9 and a limiting cap 10 connected to its upper end. During storage, after the turbine blades are placed, the axial limiting mechanism 8 is connected to the circumferential limiting tube 7 to axially limit the turbine blades, thus preventing the turbine blades from moving upward and further avoiding the risk of collision.

[0032] In one or more specific embodiments of this utility model, the connecting pipe 9 is provided with external threads and the circumferential limiting pipe 7 is provided with internal threads. Through the threaded connection, the storage and retrieval of turbine blades can be quickly realized.

[0033] In one or more specific embodiments of this utility model, in order to obtain a more effective result, the diameter of the limiting cap 10 is not greater than the outer diameter of the wheel.

[0034] In one or more specific embodiments of this utility model, in order to prevent the coating of the stored high-precision turbine blades from oxidizing due to high temperature, the high-precision turbine blade storage device further includes an ambient temperature constant structure 11. The ambient temperature constant structure 11 includes a first pipe 12, a second pipe 13, a third pipe 14, a first elbow pipe 15, and a second elbow pipe 16. One end of the first elbow pipe 15 is connected to the first pipe 12, and the other end is connected to the second pipe 13. One end of the second elbow pipe 16 is connected to the remaining end of the second pipe 13, and the other end is connected to the third pipe 14. The first pipe 12 is installed on the lower surface of the first horizontal bar 1, the second pipe 13 is installed on the lower surface of the third horizontal bar 3, and the third pipe 14 is installed on the lower surface of the second horizontal bar 2. By setting the ambient temperature constant structure 11, when the temperature is abnormal, by introducing refrigerant into the ambient temperature constant structure 11, heat is dissipated not only from the parts of the high-precision turbine blades in contact with the first horizontal bar 1 and the second horizontal bar 2, but also from the shaft hole, which can effectively prevent the coating of the stored high-precision turbine blades from oxidizing due to high temperature.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
