Description

TECHNICAL FIELD

[0001] The present application belongs to the field of full-size negative ion source, and particularly relates to a turnover mechanism system of full-size negative ion source. BACKGROUND

[0002] The turnover mechanism system of full-size negative ion source is a key component for installing full-size negative ion source in NNBI system (neutral beam injection system based on negative ion source), and its main function is to turn over the full-size negative ion source, so as to realize the installation of the full-size negative ion source. The commonly used ion source turnover system adopts the method of lifting by a travelling crane. The turnover method turns over by lifting through the travelling crane. Generally, a lifting ring is installed on the negative ion source by punching, a shackle is used on the lifting ring, and the full-size negative ion source is turned over by using a lifting belt. Such operation has a certain deformation for the full-size negative ion source. In the process of lifting, the stress is uneven, and the weight of the full-size negative ion source is very large, which will cause deformation of the ion source in the process of lifting. The ion source with large deformation does not meet the requirements of NNBI system experiment.

[0003] With the increasing maturity of magnetic confinement nuclear fusion research, the size of fusion reactor device is larger and larger, and the plasma parameter is higher and higher. The requirement for lifting of full-size negative ion source is also higher and higher. The turnover mechanism system with high automation degree and simple operation has become the first choice for future NNBI ion source turnover installation.

[0004] As a key component in the installation process of full-size negative ion source, the working performance of the turnover mechanism system is very important for the stable operation of the full-size negative ion source. Therefore, it is of great significance to carry out the design and research of the turnover mechanism system. SUMMARY

[0005] Considering that with the increasing maturity of magnetic confinement nuclear fusion research, the size of fusion reactor device is larger and larger, and the plasma parameter is higher and higher, the existing turnover mechanism system cannot meet the requirements of future negative ion source turnover installation. Compared with the traditional lifting turnover method by travelling crane, the turnover mechanism system of full-size negative ion source provided by the present application has the advantages of simple operation, low labor intensity and high turnover efficiency. The present application can be used for turning over the full-size negative ion source, and has higher turnover stability and improved turnover efficiency.

[0006] To achieve the above object, the present application adopts the following technical scheme:

[0007] A turnover mechanism system of full-size negative ion source for turning over the full-size negative ion source, comprising a guide support assembly, a turnover assembly and a driving assembly.

[0008] The guide support assembly includes two spaced-apart link support seats and 12 connecting support seats arranged along the vertical direction;

[0009] The flipping assembly includes two flipping arms and a clamping part disposed between the flipping arms. One end of the flipping arm is hinged between two fixed support seats, and the clamping part cooperates with the flipping arm to form a fixed position for fixing the full-size negative ion source to be flipped.

[0010] The drive assembly includes a drive component and a connecting flange. One end of the connecting flange is hinged to the mounting surface, and the other end is hinged to the tilting arm. The drive component includes a fixed end and a telescopic end. The fixed end of the drive component is fixed inside the tilting arm, and the telescopic end of the drive component is hinged to the tilting arm.

[0011] Furthermore, the guide support assembly includes two spaced-apart link support seats, two links, and 12 connecting support seats arranged vertically; one link support seat is equipped with four link support seat lifting lugs and six connecting support seats to facilitate hoisting after flipping, while the other link support seat is equipped with six connecting support seats. The two link support seats are fixed by bolting together the two links.

[0012] Furthermore, one end of the flipping arm of the flipping assembly is hinged between two fixed support seats, and the clamping part cooperates with the flipping arm to form a fixed position for fixing the full-size negative ion source to be flipped.

[0013] Furthermore, the bottom of the flipping component adopts a tray-shaped structure made of carbon steel, and six right-angle support seats are set on both sides of the tray base to give it higher support strength.

[0014] Furthermore, the tray base has 36 bolt holes for fixing the flipping assembly, and 15 square blocks are cut out inside it to reduce its own weight.

[0015] Furthermore, the two drive components are parallel to each other.

[0016] Furthermore, the bottom of the drive housing uses two square configuration blocks, which on the one hand increase the weight of the drive assembly, and on the other hand serve to fix and support the drive assembly.

[0017] Beneficial effects:

[0018] The application is applied to full-size negative ion source, adopts layer-by-layer fixing mode, force is uniform in the turning process, and deformation does not occur in the turning process. The application has high automation degree, simple operation, reduces labor intensity, improves turning efficiency, and reduces deformation of the full-size negative ion source in the turning process compared with the traditional travelling crane and overhead crane mode. The application realizes fixing the full-size negative ion source on the turning mechanism, and realizes the function of simply turning the full-size negative ion source, greatly improving the stability of turning.
