Description

A river water purification device

Technical Field

The invention belongs to the technical field of river water purification, in particular to a river water purification device.

Background Art

In view of the continuous improvement of society's requirements for water environment, improving surface water quality will inevitably become an important task of environmental protection. The main means of improving water quality is to plant carbon fiber grass in reservoirs or waters. It is composed of 12,000 filaments with a diameter of 7 microns. Once placed in the water, it quickly spreads out, and each of them has a fine concave and convex structure on its surface, thus forming a huge specific surface area. Using carbon fiber to purify water quality does not cause secondary pollution to the environment. It is an economical and effective method.

A patent application with publication number CN116969585A discloses a process for improving the water quality of rivers and lakes and a water purification device, including a first handle. By pulling the first handle outward, the directional square plate on the locking horizontal plate is limitedly moved in the directional long rod, and the directional spring is in a buffering state, and then the locking long rod on the locking horizontal plate leaves the locking groove and the several long grooves provided on the flat plate, so that the limiting slider can move normally, and by moving the limiting slider, it is limitedly moved in the limiting rod provided on the limiting groove, so that the several limiting sliders can arbitrarily adjust the distance between each other in the limiting groove, thereby adjusting the distance between the several carbon fiber grasses, so that the device can arbitrarily adjust the distance between the two when facing the water conditions of different waters, reducing the limitations of the device during use, thereby improving the efficiency of the several carbon fiber grasses in purifying the water quality.

There are still some problems in the actual application of the above scheme. In the process of using carbon fiber ecological grass to purify water, a large amount of pollutants in the water body of the river will gradually adhere to and accumulate on the surface of the carbon fiber ecological grass. In the device of the comparative document, only the spacing of the carbon fiber ecological grass can be adjusted to avoid the carbon fiber ecological grass being too dense or sparse to ensure the smooth flow of water and the purification effect. However, the carbon fiber ecological grass needs to be cleaned of pollutants on its surface after long-term use. If it is not cleaned, it will seriously affect its performance in adsorbing and retaining pollutants, resulting in a decrease in the purification effect, and cause the microorganisms on the carbon fiber ecological grass to die due to lack of nutrients, which also greatly reduces its purification effect. The existing method is usually to remove the carbon fiber ecological grass, and then the staff uses a brush and then sprays an environmentally friendly detergent to wash it. The cleaning process is cumbersome and the cleaning efficiency is low.

To this end, the present invention provides a river water purification device.

DETAILED DESCRIPTION

In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

Embodiment 1

As shown in Figures 1 to 11, a river water purification device described in an embodiment of the present invention includes a flat plate 1, both ends of the flat plate 1 are fixedly connected with an inclined drill rod 2, and the lower surfaces of both ends of the flat plate 1 are fixedly connected with a positioning plate 3; a through groove 12 is opened on the upper surface of the flat plate 1, and a screw 45 is rotatably arranged in the through groove 12, and the circumferential surface of the screw 45 is threadedly connected with a plurality of sliding blocks 46; the bottom end of each sliding block 46 is fixedly connected with carbon fiber ecological grass; and a sliding frame 31 that passes through one end of the flat plate 1, and the bottom end of the sliding frame 31 is rotatably provided with two cleaning rollers 5, and the surface of each cleaning roller 5 is fixedly connected with a plurality of rubber heads 51, and the carbon fiber ecological grass is arranged between the two cleaning rollers 5.

Specifically, in the process of using carbon fiber ecological grass to purify water, a large amount of pollutants in the water of the river will gradually adhere to and accumulate on the surface of the carbon fiber ecological grass. In the device of the comparative document, only the spacing of the carbon fiber ecological grass can be adjusted to avoid the carbon fiber ecological grass being too dense or sparse to ensure the smooth flow of water and the purification effect. However, the carbon fiber ecological grass needs to be cleaned after long-term use. If it is not cleaned, it will seriously affect its performance of adsorbing and intercepting pollutants, resulting in a decrease in the purification effect, and cause the microorganisms on the carbon fiber ecological grass to die due to lack of nutrients, which also greatly reduces its purification effect. The existing method is usually to remove the carbon fiber ecological grass, and then the staff uses a brush and then sprays an environmentally friendly detergent to wash it. The cleaning process is cumbersome and the cleaning efficiency is low.

Therefore, after the carbon fiber ecological grass is placed in the river channel for a period of time, which period can be regular, the water purification device with the fixed carbon fiber ecological grass is taken out from the river channel regularly, and then the staff fixes the output end of the electric push rod to the sliding frame 31, and then starts the electric push rod, the electric push rod will drive the sliding frame 31 to slide downward through the flat plate 1, and the two cleaning rollers 5 at the bottom of the sliding frame 31 will also move downward during the sliding process. The several rubber heads 51 on the surfaces of the two cleaning rollers 5 can clean the carbon fiber ecological grass between the two cleaning rollers 5 during the downward movement of the cleaning rollers 5, thereby The pollutants on the grass are cleaned off, thus completing the cleaning of the carbon fiber ecological grass. After the cleaning, the staff will test the water quality of the river in the area. If the water quality has improved, the screw 45 in the groove 12 on the upper surface of the flat plate 1 is rotated to adjust the spacing of each sliding block 46, so as to adjust the spacing of each carbon fiber ecological grass, so that the carbon fiber ecological grass can better adapt to the changes in water quality and improve the purification effect. Finally, the electric push rod is removed and the water purification device is placed in the river water body; the problems of cumbersome cleaning process and low cleaning efficiency in the existing carbon fiber ecological grass cleaning process are solved.

As shown in Figures 3 to 6, in this embodiment, two first grooves 35 are provided on the side where the two positioning plates 3 are close to each other, and a rack plate is fixedly connected to the inner wall of one side of each first groove 35; connecting shafts 311 are rotatably arranged at both ends of the sliding frame 31, and each connecting shaft 311 is fixedly connected to the corresponding cleaning roller 5; and a first gear 312 is fixedly connected to one end of the connecting shaft 311 away from the cleaning roller 5, and the first gear 312 can rotate and slide in the first groove 35, and a positioning rod 313 is fixedly connected to one end of the first gear 312 away from the connecting shaft 311, and the positioning rod 313 can slide in the second groove 36.

Specifically, in the process of the sliding frame 31 driving the cleaning roller 5 to move downward, it can also drive the cleaning roller 5 to rotate. Specifically, a first groove body 35 is opened on the side of the positioning plate 3 close to the cleaning roller 5, and then a rack plate is fixedly connected to one side of the inner wall of the first groove body 35. When the sliding frame 31 drives the rack plate to move downward, it will also drive the connecting shaft 311 to move downward. The connecting shaft 311 will drive the first gear 312 at one end thereof to move downward along the rack plate. The first gear 312 slides downward in the second groove body 36 through the positioning rod 313 at the end away from the connecting shaft 311 to limit the position. At the same time, because the positioning rod 313 and the first gear 312 are rotatably connected, the first gear 312 drives the cleaning roller 5 to rotate by driving the connecting shaft 311, so that the cleaning effect of the cleaning roller 5 on the carbon fiber ecological grass is better.

As shown in Figures 7 and 8, both ends of the sliding frame 31 of this embodiment are fixedly connected to a fixed frame 39, and a second cavity 314 is opened inside the sliding frame 31 at each end. A spring 315 is fixedly connected to the inner wall of the second cavity 314, and one end of the spring 315 away from the inner wall of the second cavity 314 is fixedly connected to a sliding plate 310. The sliding plate 310 can slide in the fixed frame 39, and the end of the sliding plate 310 away from the fixed frame 39 is rotatably connected to the connecting shaft 311.

Specifically, in the process of using the sliding frame 31 to drive the cleaning roller 5 to move downward, by fixing the fixed frames 39 at both ends of the sliding frame 31, when the sliding frame 31 moves downward, it will drive the sliding plate 310 rotatably connected to the connecting shaft 311, and the sliding plate 310 gradually moves along the sliding plate 310 to the outside of the fixed frame 39. In the process of the sliding plate 310 moving to the outside of the fixed frame 39, the spring 315 fixed to the sliding frame 31 will be pulled. Because the shapes of the two first grooves 35 are similar to the shapes of zippers, in order to prevent the rubber head 51 on the cleaning roller 5 from getting stuck in the carbon fiber ecological grass during the process of the sliding frame 31 driving the cleaning roller 5 to return upward, it is designed to be zipper-shaped, and will gradually open during the process of the cleaning roller 5 moving upward, thereby avoiding this situation.

As shown in Figure 10, a screw 45 driving assembly is arranged in the inner cavity at one end of the upper surface of the flat plate 1 in this embodiment, and the screw 45 driving assembly includes a rotating shaft 4 rotatably arranged at one end of the upper surface of the flat plate 1; a rotating handle 41 fixedly connected to the top of the rotating shaft 4, a first bevel gear 42 fixedly connected to the bottom end of the rotating shaft 4, the first bevel gear 42 is meshed with a second bevel gear 44, and the second bevel gear 44 is fixedly connected to the screw 45; and a limiting rod 43 fixedly connected to the bottom end of the first bevel gear 42.

Specifically, when adjusting the spacing between each carbon fiber ecological grass, first, the rotating plate is rotated to drive the rotating shaft 4 to rotate. During the rotation of the rotating shaft 4, the first bevel gear 42 fixedly connected to its bottom end is driven. The bottom end of the first bevel gear 42 is fixedly connected to a limiting rod 43, and the limiting rod 43 is rotatably connected to the bottom wall of the inner cavity of the flat plate 1. Then the first bevel gear 42 drives the second bevel gear 44 meshing with it. The rotation of the second bevel gear 44 can drive the screw 45 to rotate. The rotation of the screw 45 causes a number of sliding blocks 46 threadedly connected to its circumferential surface to move, thereby adjusting the spacing between each carbon fiber ecological grass.

As shown in FIG. 1 and FIG. 10 , in this embodiment, sliding grooves 11 are provided on both sides of the inner wall of the through groove 12 , and sliding blocks 47 are fixedly connected to both sides of the sliding block 46 , and the sliding blocks 47 can slide in the sliding grooves 11 .

Specifically, during the process of adjusting the rotation of the sliding block 46 , the sliding blocks 47 are fixedly connected to both sides of the sliding block 46 , and then the sliding blocks 47 are allowed to slide in the sliding grooves 11 , thereby limiting the sliding block 46 so that it can only move along the direction of the screw rod 45 .

As shown in Figure 11, in this embodiment, the two positioning plates 3 are fixedly connected to a limiting frame 49 just below the corresponding sliding block 46, and a sliding groove 48 is provided on the surface of the limiting frame 49. The bottom end of the sliding block 46 is fixedly connected to a limiting block 410, and the limiting block 410 can slide in the sliding groove 48.

Bolts 411 are threaded through the surface of the mounting frame 413.

Specifically, during the use of carbon fiber eco-grass, once the carbon fiber eco-grass is broken or damaged, it is necessary to replace the carbon fiber eco-grass by fixing a limit block 410 at the bottom end of each sliding block 46, and then placing the new carbon fiber eco-grass into the first inner cavity 412 of the mounting frame 413 fixed to the lower surface of each limit block 410, and then fixing the carbon fiber eco-grass to the bottom of the sliding block 46 through the drilled bolts 411, thereby completing the replacement and fixation.

Embodiment 2

As shown in Figures 1 to 9, comparative example 1, wherein another embodiment of the present invention is as follows: a connecting rod 318 is slidably connected to one end of the sliding frame 31, a sealing plate 319 is fixedly connected to one end of the connecting rod 318 away from the sliding frame 31, a piston block 320 is fixedly connected to one end of the sealing plate 319 away from the connecting rod 318, a first piston chamber 322 is provided at a position of the positioning plate 3 corresponding to the piston block 320 and the sealing plate 319, a compression spring 321 is fixedly connected to the bottom end of the connecting rod 318, an end of the compression spring 321 away from the connecting rod 318 is fixedly connected to the bottom wall of the first piston chamber 322, a connecting chamber 324 is provided at the bottom end of the first piston chamber 322, two second piston chambers 323 parallel to the first piston chamber 322 are provided at both ends of the connecting chamber 324, some neutral or weakly acidic detergents are placed at the bottom ends of the connecting chamber 324 and the first piston chamber 322, and a plurality of fixing holes 37 are provided at positions of the positioning plate 3 corresponding to the tops of the two second piston chambers 323.

Specifically, during the downward movement of the sliding frame 31, when the sliding frame 31 slides to half of the first rack plate, the sliding frame 31 will drive the connecting rod 318 to slide downward. During the downward sliding of the connecting rod 318, the piston block 320 at the end away from the guide block 317 will squeeze the air in the first piston chamber 322. During the continued downward movement, the neutral or weak acidic detergent in the connecting chamber 324 will be squeezed into the two second piston chambers 323. During the downward movement, the neutral or weak acidic detergent in the second piston chamber 323 will be sprayed toward the carbon fiber ecological grass along the fixing hole 37, so as to enable the cleaning roller 5 to better clean the carbon fiber ecological grass.

As shown in FIG. 4 , in this embodiment, a silicone nozzle 38 is fixedly connected to the interior of each fixing hole 37 , and the silicone nozzle 38 is used for squeezing out a neutral or weakly acidic cleaning agent.

Specifically, when the neutral or weakly acidic detergent is sprayed out from the fixed hole 37, it is because a silicone nozzle 38 is arranged in each fixed hole 37. When the pressure is insufficient, the silicone nozzle 38 can maintain the pressure in the second cavity 314 from leaking out. When the pressure reaches a certain value, the silicone nozzle 38 opens and quickly sprays out the neutral or weakly acidic detergent. The sprayed neutral or weakly acidic detergent has a strong impact force, so it can adhere to all carbon fiber ecological grass.

As shown in FIG. 7 and FIG. 8 , in this embodiment, a guide block 317 is fixedly connected to one end of the connecting rod 318 close to the sliding frame 31 , and a guide groove 316 is provided at a position of the sliding frame 31 corresponding to the guide block 317 , and the guide block 317 can slide in the guide groove 316 .

Specifically, in the process of the sliding frame 31 moving downward, when the sliding frame 31 slides to half the distance of the rack plate, the guide block 317 slides to the top of the guide groove 316, and then the sliding frame 31 will drive the guide block 317 to slide downward, thereby driving the connecting rod 318 to slide downward, and then completing the process of spraying the neutral or weak acidic detergent. In this way, the cleaning roller 5 is controlled to spray the neutral or weak acidic detergent when it moves to the middle and lower part of the carbon fiber ecological grass, so that the neutral or weak acidic detergent can flow down the carbon fiber ecological grass, so that the neutral or weak acidic detergent can better clean the carbon fiber ecological grass under the rotation of the cleaning roller 5.

As shown in Figures 1 and 3, a fixing box 32 is fixedly connected to the top of the sliding frame 31 of this embodiment, a first cavity 34 is opened in the fixing box 32, a pin rod 33 passes through the surface of the fixing box 32, and a support frame 6 is fixedly connected to the surface of the flat plate 1 on one side of the sliding frame 31, and the support frame 6 is used to place the electric push rod, and a top column 21 is fixedly connected to the upper surface of each inclined drill rod 2, and the top column 21 is used to connect the cable, and one end of the cable is fixedly connected to a float ball for positioning the purification device.

Specifically, when using the electric push rod, the output end of the electric push rod is inserted into the first cavity 34 of the fixed box 32 through the fixing box at the top of the sliding frame 31, and then fixed by the pin rod 33. The top of the sliding frame 31 and the top part of the support frame 6 are made of magnetic material, so they are magnetically attracted when not working. They are separated by the pushing of the electric push rod. Then, when lifting the water purification device, a cable is wound around the top column 21 on the upper surface of the inclined drill rod 2, and a float is fixed at one end of the cable to position the water purification device placed in the river channel, and the cables at both ends are pulled up to lift the device out of the water.

Working principle: In the process of using carbon fiber ecological grass to purify water, a large amount of pollutants in the water of the river will gradually adhere to and accumulate on the surface of the carbon fiber ecological grass. In the device of the comparative document, only the spacing of the carbon fiber ecological grass can be adjusted to avoid the carbon fiber ecological grass being too dense or sparse, so as to ensure the smooth flow of water and the purification effect. However, the carbon fiber ecological grass needs to be cleaned after long-term use. If it is not cleaned, it will seriously affect its performance of adsorbing and intercepting pollutants, resulting in a decrease in the purification effect, and cause the microorganisms on the carbon fiber ecological grass to die due to lack of nutrients, which also greatly reduces its purification effect. The existing method is usually to remove the carbon fiber ecological grass, and then the staff uses a brush and then sprays an environmentally friendly detergent to wash it. The cleaning process is cumbersome and the cleaning efficiency is low.

The cleaning roller 5 is then driven by the cleaning rod 31 to move downwardly, and the cleaning roller 5 is then driven to rotate. Then, the cleaning roller 5 is driven to rotate. The several rubber heads 51 on the surfaces of the two cleaning rollers 5 can clean the carbon fiber ecological grass between the two cleaning rollers 5 during the downward movement and rotation of the cleaning rollers 5. During the downward movement of the sliding frame 31, when the sliding frame 31 slides to half of the first rack plate, the guide block 317 slides to the top of the guide groove 316, and then the sliding frame 31 will drive the guide block 317 to slide downward, thereby driving the connecting rod 318 to slide downward. During the downward sliding of the connecting rod 318, the piston block 320 at the end away from the guide block 317 will squeeze the air in the first piston chamber 322. During the continued downward movement, the neutral or weak acidic detergent in the connecting chamber 324 will be squeezed into the two second piston chambers 323. Then, during the downward movement, the neutral or weak acidic detergent in the second piston chamber 323 will be sprayed toward the carbon fiber ecological grass along the fixing hole 37, so as to achieve the effect of making the banana head on the cleaning roller 5 better clean the carbon fiber ecological grass.

After cleaning the pollutants, the staff will test the water quality of the river in the area. If the water quality has improved, the rotating plate will be rotated to drive the rotating shaft 4 to rotate. During the rotation of the rotating shaft 4, the first bevel gear 42 fixedly connected to the bottom end thereof will be driven. The bottom end of the first bevel gear 42 is fixedly connected to a limit rod 43, and the limit rod 43 is rotatably connected to the bottom wall of the inner cavity of the flat plate 1. Then the first bevel gear 42 will drive the second bevel gear 44 meshing therewith. The rotation of the second bevel gear 44 can drive the screw 45 to rotate. The rotation of the screw 45 moves several sliding blocks 46 threadedly connected to its circumferential surface, so as to adjust the spacing between each carbon fiber ecological grass, so that the carbon fiber ecological grass can better adapt to changes in water quality and improve the purification effect. Finally, the electric push rod is removed and the water purification device is placed into the river water body.
