Description

Technical Field

[0001] This utility model relates to the field of divertor technology, specifically to a divertor target plate component that is easy to maintain. Background Technology

[0002] The divertor is a key component in magnetically confined nuclear fusion devices (such as tokamak), and its main functions are to remove plasma impurities and withstand high thermal loads.

[0003] Traditional divertor targets are made of integral casting or large-block welded structures (such as JET's carbon fiber composite target). When a part of the divertor target is damaged, it needs to be replaced as a whole because it is made of integral casting or large-block welded structures, resulting in high maintenance costs. To address this, we propose a divertor target component that is easier to maintain. Utility Model Content

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] This invention provides a divertor target plate component that is easy to maintain. Multiple target plate bodies snapped together are inserted into a support plate under the action of a positioning plate and a positioning groove. The target plate bodies are installed on the support plate through a connecting component. When the divertor target plate is partially damaged, the maintenance personnel can directly remove the damaged target plate body and replace it. Compared with the traditional whole replacement, this invention has the advantage of low maintenance cost.

[0027] Figures 1-4 The diagram shown is a structural schematic of one embodiment of a divertor target plate component that is easy to maintain. Please refer to [link / reference]. Figures 1-4 This embodiment provides a divertor target plate component that is easy to maintain, the main body of which includes a target plate assembly 100 and a connecting assembly 200.

[0028] The target plate assembly 100 includes a support plate 110 and multiple target plate bodies 120 disposed on the upper end of the support plate 110. Positioning grooves 111 are formed on both sides of the upper center of the support plate 110. Positioning plates 121 are fixed to the lower center of the two outermost target plate bodies 120 in the same row. A slot 122 is formed on the outer center of the positioning plate 121, and the positioning plate 121 is inserted into the positioning groove 111. The side walls of two adjacent target plate bodies 120 in the same row are respectively provided with locking posts 123 and locking holes 124. Two adjacent target plate bodies 120 in the same row are engaged together by the locking posts 123 and locking holes 124. Preferably, in this embodiment, each target plate body 120 is provided with two locking posts 123 and locking holes 124, ensuring stable engagement between adjacent target plate bodies 120.

[0029] The connecting assembly 200 includes an elastic element 210 disposed inside the support plate 110, a locking block 220 disposed inside the elastic element 210, and a pull rod 230 fixed to the middle of the outer side of the locking block 220. The pull rod 230 extends to the outer side of the support plate 110, and the locking block 220 engages with the locking groove 122. Preferably, in this embodiment, the connecting assembly 200 further includes a threaded rod 240 with threads disposed inside the pull rod 230. The end of the threaded rod 240 extends through the locking block 220 into the positioning plate 121. The threaded rod 240 can fix the positioning plate 121, ensuring that the positioning plate 121 is stably disposed in the positioning groove 111, preventing the target plate assembly 100 from being affected by external forces and causing the elastic element 210 to shake. The threaded rod 240 extends through the positioning plate 121 into the support plate 110. The threaded rod 240 in plate 110 further ensures a stable connection between the target plate body 120 and the support plate 110. The inner wall of the locking block 220 is inclined, and the thickness of the upper side of the inner wall of the locking block 220 is less than that of the lower side. The locking block 220 with its inclined inner wall can be squeezed outward by the positioning plate 121 when the positioning plate 121 is inserted into the positioning groove 111, thereby compressing the elastic element 210. This eliminates the trouble of manually compressing the elastic element 210 through the pull rod 230, and makes it easier for the target plate body 120 to be stably installed on the support plate 110 through the positioning plate 121.

[0030] Combination Figures 1-4This embodiment provides a divertor target plate component that is easy to maintain. Specifically, the entire target plate component consists of multiple target plate bodies 120 joined together by locking posts 123 and locking holes 124. Multiple joined target plate bodies 120 in the same row are inserted into the support plate 110 by the positioning plate 121 at the lower end of the outermost target plate body 120 and the positioning groove 111 on the support plate 110. They are then mounted on the support plate 110 by the elastic element 210, locking block 220, positioning plate 121, and locking groove 122. When the divertor target plate is partially damaged, maintenance personnel can pull the pull rod 230 outwards to remove the locking block 220 from the locking groove 122 of the positioning plate 121, thereby releasing the restriction on the target plate body 120. This allows maintenance personnel to disassemble and replace the partially damaged target plate body 120. Compared to traditional whole-body replacement, this invention has the advantage of lower maintenance costs.

[0031] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
