Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] Example:

[0024] like Figures 1 to 4 As shown, this embodiment provides a point source pollution purification device for river and lake management, including a base plate 1, a packing box 2, floats 3, and a box body 4. The box body 4 is located on the top of the base plate 1, and multiple floats 3 are located at the bottom of the base plate 1. A sewage main pipe 5 is located at the top of the box body 4 along the left-right direction. A pumping assembly 8 connected to the right end of the sewage main pipe 5 is located on the right side of the box body 4. Several sewage branch pipes 6 are evenly arranged along the front-back direction at the bottom of the sewage main pipe 5. Water outlets 7 are evenly arranged along the length direction at the bottom of the sewage branch pipes 6. Several packing boxes 2 are evenly arranged along the left-right direction below the sewage branch pipes 6 inside the box body 4. The side walls of adjacent packing boxes 2 are tightly attached to each other, and the inner wall of the box body 4 is tightly attached to the side walls of the packing boxes 2. Water passage holes 9 are evenly arranged at the top and bottom of the packing boxes 2. A drain outlet 10 is located at the bottom of the box body 4, aligned with the bottom of the packing boxes 2, and the drain outlet 10 passes through the base plate 1.

[0025] By using the float 3 and the bottom plate 1 together, the tank 4 with the filler box 2 floats at the location of the river or lake to be treated, and treats water pollution nearby. By using the sewage main pipe 5 and the sewage branch pipe 6 together, the sewage pumped by the pumping component 8 is evenly distributed to the top of each filler box 2, so as to avoid the sewage from concentrating in a single filler box 2 and affecting the sewage settling speed, thus improving the treatment efficiency. The filler is filled in the filler box 2. During subsequent maintenance, the staff only needs to replace the filler box 2 to complete the filler replacement. It is convenient to use. The filler in the filler box 2 consists of three layers: a ceramic granule layer, a crushed stone layer, and an activated carbon layer.

[0026] Furthermore, the pumping assembly 8 includes a pump 11, a water supply pipe A12, a water supply pipe B13, an inlet tank 14, a filter frame 15, and a filter screen 16. The right end of the housing 4 is provided with an inlet tank 14 located above and a pump 11 located below. The inlet of the pump 11 is provided with a water supply pipe A12 that extends underwater. The bottom end of the water supply pipe A12 is provided with a filter frame 15. The outlet of the pump 11 is provided with a water supply pipe B13 that passes through the inlet tank 14. The inlet tank 14 is provided with a horizontally placed filter screen 16. The top end of the water supply pipe B13 passes through the top of the filter screen 16. The bottom left side of the inlet tank 14 is connected to the right end of the sewage main pipe 5.

[0027] The sewage is pumped into the inlet tank 14 via the water supply pipes A12 and B13 by the pump 11. When the sewage enters the water supply pipe A12 from the river or lake, large debris is blocked by the filter frame 15. When the sewage enters the inlet tank 14 from the top of the water supply pipe B13 and flows towards the connection between the inlet tank 14 and the main sewage pipe 5, the filter screen 16 further blocks the debris in the sewage, thereby reducing the risk of the main sewage pipe 5 and the sewage branch pipe 6 being blocked by insoluble or poorly soluble debris.

[0028] Specifically, the top plate of the water inlet tank 14 is rotatably connected to the water inlet tank via a hinge. The inner wall of the water inlet tank 14 is provided with a fixing block for placing the filter screen. The fixing block rests against the bottom edge of the filter screen. When cleaning afterwards, the staff can simply lift the top plate and remove the filter screen from the water inlet tank 14 for cleaning.

[0029] Furthermore, a buffer box 17 is provided on the left side of the box body 4. The bottom right side of the buffer box 17 is connected to the left end of the sewage main pipe 5. A ventilation hole 18 is provided on the top side of the buffer box 17.

[0030] The buffer tank 17 is used to store sewage that is not discharged from the sewage main pipe 5 in time, increasing the volume of the sewage main pipe 5. Excess sewage can be discharged from the vent 18.

[0031] Furthermore, the front of the box body 4 is provided with a loading and unloading port 19, the front end of the stuffing box 2 is blocked at the loading and unloading port 19, and the closing parts of the stuffing box 2 and the loading and unloading port 19 are each provided with a corresponding latch 20.

[0032] Workers can replace the packing box 2 inside the box 4 through the loading and unloading port 19, and fix the connection between the packing box 2 and the box 4 through the locking buckle 20, which is convenient for assembly and disassembly.

[0033] Furthermore, the bottom of the box 4 is provided with a slide 21 along the front-to-back direction, and the bottom of the packing box 2 is provided with a corresponding groove 22 on the slide 21, and the groove 22 can slide on the slide 21.

[0034] The combined use of the chute 22 and the slide 21 limits the movement trajectory of the stuffing box 2 in and out of the box 4, making it convenient for staff to install the stuffing box 2 into the correct position inside the box 4.

[0035] Furthermore, counterweights 23 are provided on the side of the box 4.

[0036] The counterweight 23 is used to balance the overall center of gravity of the device and increase its weight, thereby improving the stability of the device on the water surface.

[0037] Furthermore, the bottom of the box 4 is provided with a water channel 24 that radiates evenly outward from the drain outlet 10.

[0038] The wastewater passing through the filling box 2 is guided by the water inlet trough 24 to flow more smoothly to the drain outlet 10, thereby improving drainage efficiency.

[0039] Working principle and usage process of this utility model:

[0040] The device is placed at the location of the river or lake to be treated. After being secured with ropes, the water pump 11 is started. The water pump 11 sends the sewage to the main sewage pipe 5 through the water supply pipe A12, water supply pipe B13 and water inlet tank 14. The sewage is then dispersed from the main sewage pipe 5 to each sewage branch pipe 6, and then flows from the outlet 7 on the sewage branch pipe 6 to the top of each packing box 2. The sewage then seeps into the packing box 2 through the sewage hole. The sewage is treated by passing through the packing in the packing box 2. The treated water is discharged from the drain outlet 10 at the bottom of the box 4.

[0041] When replacing the stuffing box 2, after unlocking the latch 20, pull the old stuffing box 2 out of the box body 4 from the loading and unloading port 19, put the new stuffing box 2 into the box body 4 from the loading and unloading port 19, and finally fasten the latch 20 of the installed stuffing box 2 to fix the stuffing box 2.

[0042] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
