The guiding mechanism further comprises a driving rod 13, the driving rod 13 is horizontally arranged and is perpendicular to the extending direction of the groove body of the treatment groove 1, one end of the driving rod 13 is provided with a third limiting sleeve 14 which moves synchronously with the driving rod, a motor 20 is installed on the outer side of the treatment groove 1 in the embodiment, and an output shaft of the motor 20 is connected with the other end of the driving rod 13 so as to drive the driving rod 13 and the third limiting sleeve 14 to synchronously rotate. The motor 20 may be a reduction motor.
A third limiting rod 12 is slidably inserted into the third limiting sleeve 14, and one end of the third limiting rod 12 is rotatably connected to the block body of the second connecting block 8. A backing plate 15 is fixedly sleeved on the outer side of the third limiting rod 12, and the backing plate 15 is arranged on one side, close to the second connecting block 8, of the third limiting rod 12. A spring 16 is sleeved outside the third limiting rod 12 between the third limiting sleeve 14 and the backing plate 15.
The guide mechanism further comprises a baffle 5, the baffle 5 is arranged at the top of the trash rack 2, and the top of the first limiting rod 9 is fixedly connected with the bottom of the baffle 5. In the embodiment, the baffle 5 is connected with the net placing frame 21 of the trash rack 2 through screws.

The movement track of the scraper 6 on the trash rack 2 is from top to bottom, the bottom of the treatment tank 1 is provided with a trash collection tank 22, and the trash collection tank 22 is positioned right below the scraper 6. In this embodiment, the scraping plate 6 scrapes the upper end of the upstream face of the trash rack 2 toward the lower end of the upstream face, so that the scraped impurity and dirt can be pushed into the dirt collecting groove 22 below the trash rack for collection.
In this embodiment, the operating principle of the decontamination device is as follows:
referring to fig. 4, initially, the first scraping surface of the scraping plate 6 contacts the upper end of the upstream surface of the trash rack 2, the spring 16 is in an undeformed state, and the first connecting block 7, the second connecting block 8, the first stop collar 10 and the second stop lever 11 are located at positions on the first stop lever 9 near one end of the baffle 5.
Referring to fig. 5 and 6, when the output shaft of the control motor 20 drives the driving rod 13 and the third limiting sleeve 14 to rotate clockwise synchronously, the third limiting rod 12 drives the first connecting block 7, the scraping plate 6 and the second limiting rod 11 through the second connecting block 8 to move downwards synchronously along the first limiting rod 9 under the limiting action of the first limiting sleeve 10, so that the first scraping surface of the scraping plate 6 is scraped to the bottom end from the upper end of the upstream surface of the trash rack 2, and the impurity particles intercepted on the upstream surface are scraped to the bottom of the upstream surface of the trash rack 2.
During the period, when the scraper 6 moves to a position in the middle of the upstream surface of the trash rack 2, one end of the third limiting rod 12 far away from the second connecting block 8 slides on the third limiting sleeve 14 in a direction far away from the second connecting block 8, and the spring 16 is gradually compressed and deformed (as shown in fig. 5). When the scraping plate 6 moves across the middle position of the upstream surface of the trash rack 2, one end of the third limiting rod 12, which is far away from the second connecting block 8, slides towards the direction close to the second connecting block 8 under the elastic force releasing action of the spring 16 and the driving of the third limiting sleeve 14 until the scraping plate 6 moves to the bottom end of the upstream surface of the trash rack 2, at the moment, the spring 16 does not deform, the first connecting block 7, the second connecting block 8, the first limiting sleeve 10 and the second limiting rod 11 are located at the position, which is close to one end of the bottom of the processing groove 1, on the first limiting rod 9, and the second scraping surface of the scraping plate 6 is in contact with the bottom of the processing groove 1 (as shown in fig. 6).
With the continuous driving of the driving rod 13 and the third limiting sleeve 14 driven by the output shaft of the motor 20, the third limiting rod 12 pulls the second connecting block 8 and the second connecting block 8, so that the scraper 6, the first connecting block 7 and the second connecting block 8 horizontally move in the direction away from the trash rack 2 in the treatment tank 1 under the limiting action of the second connecting block 8 and the second limiting rod 11, so that the impurity and dirt scraped by the first scraping surface of the scraper 6 are scraped into the dirt collecting groove 22 at the bottom of the treatment tank 1 through the second scraping surface of the scraper 6 (in the process, the second limiting rod 11 does not move, the spring 16 is compressed first and then extends to the initial state, and the scraper 6 is separated from the upstream surface of the trash rack 2) until the second connecting block 8 moves to the side of the rod body of the second limiting rod 11 away from the trash rack 2.
Referring to fig. 7, the second connecting block 8 drives the first connecting block 7, the scraper 6, the first position-limiting sleeve 10 and the second position-limiting rod 11 to move along the first position-limiting rod 9 toward the baffle 5 to the height of the rod body of the scraper 6 on the first position-limiting rod 9 at the beginning (in this process, the spring 16 is compressed and then extended to the initial state, and the scraper 6 does not contact the upstream surface) under the driving of the third position-limiting rod 12.
Then, the second connecting block 8 is driven by the third limiting rod 12 to drive the first connecting block 7 and the scraper 6 to move along the second limiting rod 11 toward the trash rack under the limiting effect of the second connecting block 8 and the second limiting rod 11, so that the scraper 6, the first connecting block 7 and the second connecting block 8 return to the original positions again.
The process is continuously reciprocated along with the continuous driving of the motor 20, so that the scraping plate 6 forms a rectangular motion track to scrape the upstream surface of the trash rack 2 in a one-way circulating manner, thereby completing the efficient decontamination of the trash rack 2, and ensuring the effective rate of the trash rack 2 for intercepting impurities and dirt and the stability of the water flow circulation in the treatment tank 1.
The tail water treatment and circulation system for micropterus salmoides breeding further comprises a box body 4, the box body 4 is arranged in the treatment tank 1, and the box body 4 is positioned in the downward flow direction of the trash rack 2. The box 4 is close to trash rack 2 one side and installs immersible pump 19, and intercommunication in immersible pump 19 output and the box 4, a plurality of through-holes (not marked) have been seted up at the top of box 4, and guide plate 17 is installed at the top of box 4.
The submerged pump 19 can pump the water in the treatment tank 1 into the box body 4, so that the water returns to the treatment tank 1 after being cut and jumped by the through holes, the water body is fully contacted with the air, the oxygen content of the water body is improved, the water flow velocity in the treatment tank 1 can be accelerated, and the tail water treatment efficiency is improved.
One end of the guide plate 17 is fixed at one side of the top of the box body 4 close to the trash rack 2, and the other end of the guide plate is bent upwards towards the other side of the top of the box body 4. The orthographic projection area of one side of the guide plate 17 facing the top of the box body 4 covers the positions of all the through holes. The cross section of the deflector 17 in this embodiment is a quarter circular structure. The guide plate 17 can prevent the water flow from splashing and jumping out of the treatment tank 1 after being sprayed out through the through holes, and can guide the water flow into the treatment tank 1. The top of the box body 4 is provided with a plurality of aeration pipes 18, and a large amount of bubbles can be blown into the water flow which is divided by the through holes through the aeration pipes 18, so that the oxygen content in the water is further improved.
