DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

[0019] Please refer to Figs. 1-3The utility model relates to a water purification device for eel culture, which comprises a culture pond 1, a collecting box 2 detachably installed at the bottom of the culture pond 1 and in communication with the culture pond 1, a fixed frame 3 fixedly connected to the top of the culture pond 1, a motor 4 fixedly installed on the fixed frame 3, a driving shaft 5 fixedly connected to the output end of the motor 4, a spiral blade 6 arranged on the driving shaft 5, and a pushing and scraping mechanism arranged on the fixed frame 3 for cleaning fecal waste into the collecting box 2.

[0020] Through the above technical scheme, the fecal waste and other waste produced by eels can be accumulated at the bottom of the culture pond 1 during use, and the pushing and scraping mechanism can scrape the waste into the collecting box 2 for collection, thereby reducing the accumulation of waste at the bottom of the culture pond 1 and the stirring of the waste by eels swimming and touching the bottom to make the pond water turbid.

[0021] Specifically, the pushing and scraping mechanism comprises a rotating frame 7 fixedly sleeved on the outer surface of the driving shaft 5, and first plate shafts 8 rotatably connected to both ends of the rotating frame 7.

[0022] Through the above technical scheme, the rotating frame 7 can push and pull the corresponding first recessed plates 9 and connecting rods 10 through the first plate shafts 8 during rotation.

[0023] Specifically, the outer surface of each first plate shaft 8 is fixedly sleeved with a first recessed plate 9, and the outer surface of each first recessed plate 9 is fixedly connected with a connecting rod 10.

[0024] Through the above technical scheme, the rotating frame 7 can rotate along the first plate shaft 8 during the pushing and pulling of the first recessed plate 9.

[0025] Specifically, one end of each connecting rod 10 away from the first recessed plate 9 is fixedly connected with a second recessed plate 11, and the inner side of each second recessed plate 11 is fixedly provided with a second plate shaft 14.

[0026] Through the above technical scheme, the connecting rod 10 can make the sliding frame 13 rotate along the second plate shaft 14 during the pushing and pulling of the second plate shaft 14 by the second recessed plate 11.

[0027] Specifically, the fixed frame 3 is provided with a guide rail 12, the outer surface of the guide rail 12 is slidingly connected with a sliding frame 13, and the inner surface of the sliding frame 13 is rotatably connected with the outer surface of the second plate shaft 14.

[0028] Through the above technical scheme, the sliding frame 13 can slide along the guide rail 12 after being driven, thereby moving the scraper 15 at the end of the sliding frame 13 along the bottom of the culture pond 1.

[0029] Specifically, one end of the sliding frame 13 away from the guide rail 12 is provided with a scraper 15.

[0030] Through the above technical scheme, the two groups of scrapers 15 will scrape the excrement and other waste into different collection boxes 2 at the bottom end of the breeding pond 1 during the reverse movement, and the collection boxes 2 have a certain depth, so that the collected waste is not easy to be stirred back into the breeding pond 1.

[0031] Working principle: During the breeding of eels in the breeding pond 1, the excrement and other waste produced by the eels will accumulate at the bottom of the breeding pond 1. Considering that the eels will touch the bottom when swimming, the waste will be stirred, so that it will be suspended in the water, causing the water to become turbid, accelerating the role of bacteria, and causing the oxygen in the water to be quickly consumed. At this time, the motor 4 can be started to drive the driving shaft 5 to rotate, and then the rotating frame 7 is driven to rotate. During the rotation of the rotating frame 7, the first plate shaft 8 can push and pull the first concave plate 9, and the connecting rod 10 can push and pull the second concave plate 11 and the second plate shaft 14 to push and pull the sliding frame 13, so that the sliding frame 13 slides along the guide rail 12. That is, the scraper 15 at the end of the sliding frame 13 will be attached to the bottom of the breeding pond 1, and during the process of approaching and moving away from each other, the excrement and other waste will be scraped into the collection box 2. Since the collection box 2 has a certain depth, the collected waste is not easy to be stirred back into the breeding pond 1. Compared with the excrement and other waste accumulated at the bottom of the breeding pond 1, the turbidity of the water caused by the stirring of the waste is effectively reduced, thereby reducing the consumption of dissolved oxygen in the water. During the rotation of the driving shaft 5, the helical blade 6 will rotate synchronously. When the helical blade 6 rotates, it will generate a vortex, forming a space where air is sucked in. This space will move downward in the spiral motion, bringing air into the water. This vortex effect can effectively introduce air into the water, and the movement of the helical blade 6 will also break the surface tension of the water, forming bubbles around it, further increasing the probability of air entering the water, thereby increasing the oxygen content in the water to improve the water quality.

[0032] Although embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the application, the scope of which is defined by the appended claims and their equivalents.
