Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of anti-clogging components for water inlets in hydropower generation, specifically an anti-clogging component for water inlets in hydropower generation. Background Technology
[0002] As is well known, hydropower generation requires water to be introduced into hydropower generator sets as the power to drive the generator sets. However, the water contains a large amount of large particles of silt and floating debris. If it is directly input into the generator sets without filtration, it can easily cause blockages and prevent the generator sets from operating normally. In order to prevent a large amount of floating debris and large particles of silt from being directly introduced into the generator sets, existing technologies mostly install filter screens and other interception structures at the water inlet of hydropower plants to filter the water. Although this can achieve the effect of filtering the water source, it is not the only way to do so.
[0003] However, large particles of silt, floating debris, and other impurities intercepted tend to accumulate on the filter screen, causing blockages at the inlet and affecting its use. This necessitates frequent manual cleaning. Therefore, we propose a hydroelectric power generation inlet anti-clogging component to solve the above problems. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides an easy-to-use anti-clogging component for hydropower inlets.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a water inlet anti-clogging component for hydropower generation, comprising a square filter frame, a threaded inlet positioning groove at the rear end of the square filter frame, an anti-clogging fixing frame on the outside of the square filter frame, the anti-clogging fixing frame cooperating with the square filter frame, several drainage grooves at the left, right, top, and bottom ends of the anti-clogging fixing frame, an inclined slot baffle at the front end of each drainage groove, and threaded holes at the top left, top right, bottom left, and bottom right parts of the anti-clogging fixing frame, each threaded hole being fitted with a positioning bolt, and each positioning bolt cooperating with the threaded hole.
[0008] Furthermore, an improvement of this utility model is that each inclined slot baffle and anti-blocking fixing frame are integrated into one structure.
[0009] Furthermore, the improvements of this utility model include that the square filter frame, the threaded inlet positioning groove, the anti-clogging fixing bracket, the leakage groove, the inclined hole groove baffle, and the edges of the threaded hole and the positioning bolt are all rounded.
[0010] Based on the above, the improvement of this utility model is that the anti-clogging fixing bracket and the square filter frame are fitted by a sliding fit.
[0011] Furthermore, an improvement of this utility model is that the fit between each positioning bolt and the threaded hole is a threaded fit.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-3This utility model discloses an anti-clogging component for a hydroelectric power inlet, comprising a square filter frame 1, a threaded inlet positioning groove 2 at the rear end of the square filter frame 1, and an anti-clogging fixing frame 3 on the outside of the square filter frame 1. The anti-clogging fixing frame 3 cooperates with the square filter frame 1 in a sliding fit, allowing the anti-clogging fixing frame 3 to slide and adjust along the square filter frame 1. Several drainage grooves 4 are provided at the left, right, top, and bottom ends of the anti-clogging fixing frame 3, and an inclined slot baffle 5 is provided at the front end of each drainage groove 4. Each inclined slot baffle 5 and the anti-clogging fixing frame 3 are integrally formed, making the inclined slot baffle 5 and the anti-clogging fixing frame 3 more firmly fixed. The top left, top right, bottom left, and bottom right of the device are all provided with threaded holes 6. Each threaded hole 6 is provided with a positioning bolt 7. Each positioning bolt 7 mates with the threaded hole 6. The mating method between each positioning bolt 7 and the threaded hole 6 is threaded engagement, allowing the positioning bolt 7 to be adjusted along the threaded hole 6. The edges of the square filter frame 1, threaded inlet positioning groove 2, anti-clogging fixing bracket 3, leakage groove 4, inclined hole groove baffle 5, threaded holes 6, and positioning bolts 7 are all rounded, so that the anti-clogging component of the hydropower inlet will not scratch the user during use. When in use, the anti-clogging component of the hydropower inlet can block most of the debris in the water discharged into the inlet at the inclined hole groove baffle 5, thereby effectively reducing the possibility of clogging and reducing the frequency of cleaning.
[0021] In summary, this anti-clogging component for hydropower inlets allows the square filter frame 1 to be fixed to the inlet via the threaded inlet positioning groove 2 during use. When water is being introduced, debris is blocked by several inclined slot baffles 5 on the anti-clogging mounting bracket 3. Due to their inclined design, most debris is blocked on the inclined slot baffles 5 during water delivery, preventing it from affecting the water intake of the square filter frame 1. This anti-clogging component effectively blocks most debris in the water entering the inlet via the inclined slot baffles 5, thus reducing the possibility of clogging and the frequency of cleaning. Therefore, this anti-clogging component for hydropower inlets offers better performance.
