[0002] The sewage treatment industry has become an emerging industry, which is of equal importance to the industries of tap water production, water supply, drainage, and reclaimed water reuse. The organic matter in wastewater is extremely unstable and easily decomposes to produce foul odors. Bacteria and pathogens multiply rapidly using the organic matter in domestic wastewater as nutrients, which can lead to the spread of infectious diseases. Wastewater treatment ponds are required for wastewater treatment.

[0003] After retrieval, the Chinese patent with the publication number "CN220328005U" discloses a wastewater treatment pond that is convenient to clean, including a treatment pond. A fixed block is fixedly installed on the surface of the treatment pond, and a cleaning mechanism is arranged on the surface of the treatment pond. The cleaning mechanism includes a support frame that is slidably installed on the surface of the treatment pond. A first motor is fixedly installed on the surface of the support frame. The number of the first motors is two. A connecting rod is fixedly installed at the output end of the first motor. The number of the connecting rods is two. This wastewater treatment pond that is convenient to clean can facilitate the user to clean the bottom of the treatment pond when the user maintains the wastewater treatment pond, and can facilitate the user to clean the impurities and sludge deposited at the bottom of the treatment pond completely, without the user using tools for manual cleaning, reducing the working intensity of the user and lowering the cleaning cost of the treatment pond. However, the prior art has the following deficiencies in use:

[0004] The impurities at the bottom of the treatment pond are cleaned by two rotating brushes. The cleaning effect of the brushes is poor. At the same time, it is difficult for the cleaned impurities to be completely discharged through the sewage pipe, and some impurities will remain in the treatment pond, which has certain drawbacks in actual work.

[0005] Therefore, there is an urgent need for a bottom cleaning device for wastewater treatment ponds to solve the above problems. Summary of the Utility Model

[0006] The purpose of the present utility model is to address the existing problem that the impurities at the bottom of the treatment pond are cleaned by two rotating brushes, the cleaning effect of the brushes is poor, and at the same time, it is difficult for the cleaned impurities to be completely discharged through the sewage pipe, and some impurities will remain in the treatment pond, which has certain drawbacks in actual work.

[0032] Embodiment:

[0033] As Figures 1-5 shown, a bottom cleaning device for a wastewater treatment tank proposed in this embodiment includes a treatment tank 1. A first fixing block 2 and a second fixing block 3 are fixedly connected to the top of the treatment tank 1. A forward and reverse motor 4 is fixedly installed on the right side wall of the first fixing block 2. The output end of the forward and reverse motor 4 is fixedly connected to a lead screw 5. By driving the lead screw 5 to rotate through the forward and reverse motor 4, a U-shaped frame 6 is threadedly sleeved on the lead screw 5. The U-shaped frame 6 moves horizontally to the left. Symmetrically distributed connecting rods 7 are fixedly connected to the bottom side of the U-shaped frame 6. A scraper 8 is fixedly installed at the bottom of the two connecting rods 7. The connecting rods 7 and the scraper 8 move along with the U-shaped frame 6. The impurities at the bottom of the treatment tank 1 are scraped and cleaned by the moving scraper 8. A discharge port 9 is opened on the left side of the treatment tank 1. A discharge frame 10 is fixedly installed on the left side wall of the treatment tank 1. A slot 11 is opened on the discharge frame 10. A baffle 12 is inserted into the slot 11. A connecting plate 13 is fixedly connected to the top of the baffle 12. An installation plate 14 is fixedly connected to the left side wall of the treatment tank 1. An electric push rod 15 is fixedly connected to the bottom of the installation plate 14. The push rod end of the electric push rod 15 is fixedly connected to the connecting plate 13. By driving the connecting plate 13 to move upward through the electric push rod 15, the baffle 12 is disengaged from the slot 11. When the scraper 8 moves to the left end in the treatment tank 1, the impurities at the bottom of the treatment tank 1 are discharged out of the treatment tank 1 through the discharge port 9, and the impurities are finally discharged through the discharge frame 10, improving the efficiency of impurity discharge and preventing impurities from remaining in the treatment tank 1 and being unable to be discharged.

[0034] As Figure 1 and Figure 2As shown in the figure, fixed frames 16 are fixedly connected to both the front and rear end faces of the treatment tank 1. Horizontally arranged fixed rods 17 are fixedly connected to both of the two fixed frames 16, and sliding blocks 18 are slidably connected to both of the two fixed rods 17.

[0035] As Figure 1 shown in the figure, both of the two sliding blocks 18 are fixedly connected to the U-shaped frame 6. By driving the lead screw 5 to rotate through the forward and reverse motor 4, the U-shaped frame 6 moves horizontally to the left, and the two sliding blocks 18 slide to the left on the fixed rods 17, which can prevent the position of the U-shaped frame 6 from shifting during movement.

[0036] As Figure 2 shown in the figure, support legs 19 are fixedly connected to the four corners at the bottom of the treatment tank 1, and the treatment tank 1 is supported by the four support legs 19.

[0037] As Figure 1 and Figure 5 shown in the figure, the bottom of the baffle 12 is in contact with the inner wall of the discharge frame 10.

[0038] As Figure 1 and Figure 3 shown in the figure, the end of the lead screw 5 far from the forward and reverse motor 4 is rotatably connected to the second fixed block 3 through a bearing, ensuring the stability of the lead screw 5 during rotation.

[0039] Specifically, when the bottom cleaning device for the wastewater treatment tank is in use: connect the forward and reverse motor 4 and the electric push rod 15 to an external control power supply to supply power to the forward and reverse motor 4 and the electric push rod 15. Drive the lead screw 5 to rotate through the forward and reverse motor 4, the U-shaped frame 6 moves horizontally to the left, and the two sliding blocks 18 slide to the left on the fixed rods 17, which can prevent the position of the U-shaped frame 6 from shifting during movement. The connecting rod 7 and the scraper 8 move along with the U-shaped frame 6, and the impurities at the bottom of the treatment tank 1 are scraped and cleaned by the moving scraper 8. Compared with brush cleaning, the cleaning effect of the impurities at the bottom of the treatment tank 1 can be improved. Then, drive the connecting plate 13 to move upward through the electric push rod 15, so that the baffle 12 disengages from the slot 11. When the scraper 8 moves to the left end in the treatment tank 1, the impurities at the bottom of the treatment tank 1 are discharged out of the treatment tank 1 through the discharge port 9, and the impurities are finally discharged through the discharge frame 10, improving the efficiency of impurity discharge and preventing impurities from remaining in the treatment tank 1 and being unable to be discharged.

[0040] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific embodiments. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and their improvements that do not deviate from the spirit and scope of the invention are covered by the scope of the claims of the present invention.
