Description

Technical Field

[0001] The utility model relates to the field of hydropower generation, in particular to a dirt blocking device for hydropower generation. Background Art

[0002] Hydroelectric power generation is achieved by using water power to drive the rotation of the turbine, converting water energy into mechanical energy. The hydraulic turbine is connected to the generator, and as the turbine rotates, it can drive the generator to generate electricity. However, there is an immeasurable amount of dirt in the water. If this dirt is allowed to participate in hydroelectric power generation along with the water flow, the hydraulic turbine will become fragile, greatly reducing the service life and power generation efficiency of the hydroelectric power generation equipment.

[0003] After searching, the Chinese patent announcement number CN221144649U is found, which discloses a detachable dirt barrier device for hydropower generation. In this patent, the water body will first contact the cone block and then flow to the filter screen. During the process, the water body collides with the cone block. Since the cone block is conical, the water body is dispersed to the surroundings. At the same time, the cone block can buffer the impact force of the water body under the elastic support of the spring, thereby playing a role in energy dissipation. The water body after energy dissipation is then filtered through the filter screen, and the filtration will not be subjected to a huge impact force, thus solving the problem that due to the large impact force of the water flow, although the existing technology is provided with a buffer device, the water flow still directly impacts the filter screen, and the filter screen is under stress for a long time, affecting the service life.

[0004] However, during long-term use, garbage and dirt will gradually accumulate on the filter, squeezing the filter and affecting the filtering effect. Utility Model Content

[0005] The purpose of the present utility model is to provide a dirt blocking device for hydropower generation in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A dirt blocking device for hydropower generation includes a connecting pipe, a filter plate fixedly connected between the inner walls of the connecting pipe, the filter plate is in the shape of a cone with the tip facing upward, and a cleaning mechanism is provided on the top of the filter plate. The cleaning mechanism includes a rotating shaft, a connecting block fixedly connected to the rotating shaft, and a plurality of groups of circumferentially arranged first scrapers fixedly connected to the connecting block. The ends of the first scrapers are fixedly connected to second scrapers, the first scrapers and the second scrapers are tightly attached to the outer walls of the filter plates, and the second scrapers are elastic. The cleaning mechanism also includes a power component and a plurality of circumferentially arranged collection components. The power component is used to drive the rotating shaft to rotate, and the collection component is used to collect scraped debris.

[0008] Preferably, the collecting assembly includes a protective box fixedly connected to the outer wall of the connecting tube, the inner wall of the connecting tube is provided with a discharge port connected to the interior of the protective box, the discharge port is located above the contact edge of the filter plate and the connecting tube, a collecting box is slidingly connected between the inner walls of the protective box, a plurality of drainage holes are provided at the bottom of the collecting box, and a guide pipe is connected between the bottom of the protective box and the connecting tube.

[0012] Preferably, the front side of the collection box extends out of the protective box and is welded with a handle.

[0013] The beneficial effect is that the first scraper is driven by the rotating shaft to drive the second scraper to rotate.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1-Figure 5 As shown, a dirt blocking device for hydropower generation includes a connecting pipe 1. The top of the connecting pipe 1 is bolted with a protective cover 101. The protective cover 101 blocks hard objects in the water body to prevent the hard objects from entering the connecting pipe 1 and causing damage to internal devices or water conservancy equipment. The inner walls of the connecting pipe 1 are bolted with filter plates 2. The filter plates 2 are conical in shape with the tip facing upward, so that the filtered debris accumulates at the bottom of the filter plate 2 for easy collection.

[0026] A cleaning mechanism is provided on the outer wall of the filter plate 2, which is used to clean debris on the filter plate 2. The cleaning mechanism includes a rotating shaft 401, which is rotatably connected to the bottom of the protective cover 101, and a connecting block 403 is fixedly connected to the rotating shaft 401. A plurality of groups of circumferentially arranged first scrapers 404 are fixedly connected to the connecting block 403, and the ends of the first scrapers 404 are fixedly connected to the second scrapers 405. The first scrapers 404 and the second scrapers 405 are tightly attached to the outer wall of the filter plate 2, and the second scrapers 405 are elastic.

[0027] The cleaning mechanism also includes a power component, which is used to drive the rotating shaft 401 to rotate. The power component includes a number of circumferentially arranged fan blades 402, which are fixedly connected to the outer wall of the rotating shaft 401. The potential energy of the water flow is used to drive the fan blades 402 to rotate the rotating shaft 401, avoiding the use of additional power and improving resource utilization.

[0028] The cleaning mechanism also includes multiple groups of circumferentially arranged collecting components, which include a protective box 301 bolted to the outer wall of the connecting pipe 1, and a discharge port connected to the inside of the protective box 301 is provided on the inner wall of the connecting pipe 1, and the discharge port is located above the contact edge of the filter plate 2 and the connecting pipe 1. A collecting box 303 is slidably connected between the inner walls of the protective box 301, and the front side of the collecting box 303 extends out of the protective box 301 and is welded with a handle. A number of drainage holes are provided at the bottom of the collecting box 303, and a guide pipe 304 is connected between the bottom of the protective box 301 and the connecting pipe 1. The outer wall of the connecting pipe 1 is fixedly connected to a baffle 302 located in the protective box 301, and the baffle 302 is tilted downward. The baffle 302 is located between the discharge port and the collecting box 303 to prevent water from entering the protective box 301 and causing backflow, thereby flushing the debris collected in the collecting box 303 back onto the filter plate 2, affecting the filtering effect.

[0029] Working principle: When in use, water enters the connecting pipe 1 from the upper end of the connecting pipe 1, and flows out of the connecting pipe 1 after being filtered by the filter plate 2. Before the water enters the connecting pipe 1, the protective cover 101 is used to block the hard objects in the water to prevent the hard objects from entering the connecting pipe 1 and causing damage to the internal devices or water conservancy equipment. When the water passes through the filter plate 2, it is dispersed to the surrounding areas of the filter plate 2 under the guidance of the filter plate 2, and then flows along the filter plate 2. Therefore, most of the filtered debris will be filtered to the bottom end of the filter plate 2, and part of the water flow directly enters the protective box 301 through the discharge port, and the debris is filtered to In the collecting box 303, the water flows back into the connecting pipe 1 through the guide pipe 304. While the water flows, it drives the fan blade 402 to drive the rotating shaft 401 to rotate, and the rotating shaft 401 drives the connecting block 403 to rotate. The connecting block 403 drives the first scraper 404 to drive the second scraper 405 to rotate. When the second scraper 405 abuts against the inner wall of the connecting pipe 1, the second scraper 405 produces elastic deformation. When the second scraper 405 rotates to the discharge port, the second scraper 405 loses its restriction, the elastic force is released, and the scraped debris is bounced into the protective box 301, thereby cleaning the debris accumulated at the bottom end of the filter plate 2.

[0030] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
