It is an important part of a hydraulic structure and can be used to intercept water flow, control water level, regulate flow rate, discharge sediment and floating objects, etc.; the gate includes a rotating gate and a vertical gate. When setting a rotating gate, the lower end of the gate plate will slide and contact around the bottom. The bottom of the existing gate plate is connected to the bottom shaft. When the bottom shaft rotates, it needs to rotate around the support sleeve.

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] AsFigure 1 - Figure 2 As shown in Figure 1 - Figure 2 , an embodiment of the present utility model provides a large bottom - shaft arc - shaped support assembly, including a base 100. Above the base 100, there is a support arc seat 200 for supporting the bottom shaft. The support arc seat 200 and the base 100 are connected by a strengthening member. The outer side of the support arc seat 200 is an arc - shaped structure. The upper support surface of the support arc seat 200 matches the outer diameter of the bottom shaft. Inside the support arc seat 200, there is a wear - resistant member in contact with the bottom shaft. At the upper end of the support arc seat 200, there is a limiting mechanism for limiting the upper end of the support arc plate 202. Through the limiting mechanism, the wear - resistant member is prevented from moving, so as to maintain it in the support position and facilitate later maintenance;
[0025] The limiting mechanism includes a locking pressure plate 300 that matches the upper end of the support arc seat 200. The locking pressure plate 300 is connected to the support arc seat 200 by a bolt member 301. At the lower end of the locking pressure plate 300, there is a limiting pressure groove 304. A limiting pressure plate 303 is fitted in the limiting pressure groove 304. The end of the limiting pressure plate 303 extends to the upper end position of the support arc plate 202. After installation, the upper end of the support arc plate 202 contacts the bottom of the limiting pressure plate 303, so that the two ends of the support arc plate 202 can be limited to prevent it from shifting;
[0026] On the side of the limiting pressure plate 303 facing the bottom shaft, there is a scraping strip 302. The scraping strip 302 is in pressing contact with the outer side of the bottom shaft. On the one hand, it is to prevent the limiting pressure plate 303 from contacting the bottom shaft. On the other hand, it is to scrape large - particle impurities on the outer side of the bottom shaft to avoid the problem of excessive wear caused by stones entering the rotation area;
[0027] The wear - resistant member includes a limiting arc groove 201 provided at the support position of the support arc seat 200. The inner diameter of the limiting arc groove 201 matches the outer diameter of the bottom shaft. A support arc plate 202 is fitted in the limiting arc groove 201. At both ends of the limiting arc groove 201, there are limiting edges for limiting the support arc plate 202 to prevent the support arc plate 202 from slipping out of the axis. When disassembling later, it is necessary to knock the support arc plate 202 from one side so that the support arc plate 202 rotates around the bottom shaft and comes out;
[0028] The support arc plate 202 is made of stainless - steel material, which can greatly improve the service life of the component;
[0029] The support arc plate 202 can be an integral structure or composed of multiple semi - rings. The split - type structure is convenient for taking out one by one later, reducing the difficulty of taking out. The integral structure has a large damping when taking out, but the replacement is fast;
[0030] The reinforcing member includes a plurality of connecting support arc seats 200 and first reinforcing ribs 101 connecting the base 100. A plurality of second reinforcing ribs 102 connecting to the base 100 are arranged on the outer side of the first reinforcing ribs 101. The intersecting second reinforcing ribs 102 and first reinforcing ribs 101 improve the connection strength between the base 100 and the support arc seats 200. During later installation, the base 100 and the first reinforcing ribs 101 are embedded in concrete.
[0031] Working principle: During actual installation, a plurality of support arc seats 200 are arranged under the bottom shaft to support the bottom shaft, so that the weight of the support sleeve can be shared and excessive wear can be avoided. Moreover, the upper half of the bottom shaft of the support assembly here is in an exposed state, and water is well utilized for lubrication to reduce wear. During later maintenance, only the limiting mechanism needs to be removed, and then the side of the support arc plate 202 is tapped to make the support arc plate 202 rotate around the bottom shaft, so that the support arc plate 202 can be rotated out of the limiting arc groove 201, and then a new support arc plate 202 can be replaced in the same way.
[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
