Description

Technical Field

[0001] The invention relates to the technical field of water treatment, in particular to a dam used for intercepting and purifying suspended pollutants in water. Background Art

[0002] In the field of environmental protection and water resources management, dams, as important water conservancy facilities, not only undertake multiple functions such as water storage, irrigation, and power generation, but also increasingly become important barriers to intercept and purify suspended pollutants in water. With the acceleration of industrialization and the improvement of urbanization, water pollution problems are becoming increasingly serious, especially suspended pollutants in natural water bodies such as rivers and lakes, such as sediment, algae, and organic debris, which have a serious impact on water quality and threaten ecological security and human health.

[0003] At present, there are many dam technologies on the market for intercepting and purifying suspended pollutants in water. Among them, the most common one is the combination of physical interception and sedimentation. This type of dam usually sets grids or filters in the water flow entry area to intercept larger particles of suspended matter. Then, the suspended matter is deposited at the bottom of the dam or in a specific area through natural sedimentation of the water flow or with the help of artificial accelerated sedimentation, thereby achieving the purpose of purification.

[0004] However, the existing technology still has many defects in practical applications:

[0005] Limited interception efficiency: Traditional grilles or filters can only intercept larger suspended matter, and are not very effective at intercepting smaller suspended matter.

[0036] The connecting member 56 includes a support seat 518 fixedly mounted on the movable frame 51, a fixing rod 519 fixedly connected to the support seat 518, a slide plate 520 slidably connected to the fixing rod 519, an inner end of the slide plate 520 is fixedly connected to the pressing plate 55, and an outer end of the slide plate 520 is fixedly connected to a connecting plate 522, and the connecting plate 522 is slidably mounted on the movable frame 51, and a row of pushing grooves 523 are provided on the surface of the connecting plate 522;

[0037] The push member 57 includes a slide groove opened in the movable frame 51, and a positioning rod 524 is fixedly connected in the slide groove, and a sliding plate 525 is slidably connected to the positioning rod 524. The outer wall of the positioning rod 524 is sleeved with a third damping spring 526 located at the bottom of the sliding plate 525. An extension plate 527 is fixedly connected to the outer end of the sliding plate 525. The extension plate 527 is rotatably connected to a push rod 528 through a torsion spring. The bottom end of the push rod 528 corresponds to the position of the push groove 523. Under the elastic force of the torsion spring, the push rod 528 is pushed to move to the left side. A convex rod 529 is fixedly connected to the top of the extension plate 527, and the position of the convex rod 529 corresponds to the position of the inclined plate 517. A limit rod 530 is threadedly connected to the sliding plate 525, and one end of the limit rod 530 corresponds to the position of the push rod 528.

[0038] The left end of the fixed frame 2 is fixedly connected to a connecting seat 531, which is located above the highest point of the first moving roller 32, so that after the suspended pollutants are broken up, it is convenient for the conveyor belt 34 and the salvage plate 35 to discharge the suspended pollutants. A rotating rod 532 is rotatably connected to the connecting seat 531, and a plurality of levers 533 are fixedly connected to the outer wall of the rotating rod 532. Guide plates 534 are fixedly connected to both ends of the rotating rod 532, and the other end of the guide plate 534 is movably connected to a connecting rod 535, and the other end of the connecting rod 535 is movably connected to the L-shaped connecting frame 510.

[0039] In the embodiment of the present invention, by starting the servo motor 511, the cam 512 can be driven to rotate synchronously. During the rotation process, the cam 512 can effectively push the L-shaped connecting frame 510 to move to the right. As the L-shaped connecting frame 510 moves, the swing rod 59 and the inclined plate 517 will also slide to the right on the lifting frame 58. This series of actions causes the first knocking rod 514 to move to the right, thereby knocking the conveyor belt 34. As the cam 512 continues to rotate, under the elastic action of the first damping spring 513, the L-shaped connecting frame 510 and the swing rod 59 will move to the left. During the resetting of the swing rod 59, the lifting frame 58 moves up and down on the cross bar 52, thereby driving the second knocking rod 515 and the third knocking rod 516 to move up and down. In this way, the second knocking rod 515 and the third knocking rod 516 can also knock the conveyor belt 34. Through the joint action of the first knocking rod 514, the second knocking rod 515 and the third knocking rod 516, the fine suspended matter on the inner wall of the conveyor belt 34 can be effectively knocked loose and fall off. This knocking treatment can not only clean the conveyor belt 34, but also reduce its running resistance, thereby improving the conveying efficiency and stability.

[0040] When the inclined plate 517 moves to the right, it pushes the protruding rod 529 to move downward, and the protruding rod 529 drives the extension plate 527, the pushing rod 528 and the sliding plate 525 to move downward, and compresses the third damping spring 526. In the process of the pushing rod 528 moving downward, the pushing groove 523 cooperates to push the connecting plate 522, the sliding plate 520 and the sliding plate 525 to move to the right. When the sliding plate 520 slides to the right on the fixed rod 519, it compresses the second damping spring 521. At the same time, when the pressing plate 55 moves to the right in the collecting frame 54, it can extrude and form the suspended pollutants in the collecting frame 54. The moisture generated during the extrusion process will be discharged through the filter holes at the bottom of the collecting frame 54. When moving to the left, under the elastic force of the third damping spring 526, the sliding plate 525, the extension plate 527, the push rod 528 and the protruding rod 529 will move upward and reset. At the same time, under the elastic force of the second damping spring 521, the pressing plate 55, the sliding plate 520 and the connecting plate 522 will also move and reset. Through this reciprocating motion, the pressing plate 55 can repeatedly extrude and shape the suspended pollutants and dehydrate the water in the suspended pollutants. This repeated extrusion not only promotes the condensation and formation of the suspended pollutants, but also greatly enhances the dehydration effect, which helps to reduce the volume of the suspended pollutants in the subsequent treatment process, reduce the treatment cost, and may increase the recovery rate of the suspended pollutants.

[0041] During the back and forth movement of the L-shaped connecting frame 510, the connecting rod 535 will also move back and forth accordingly. Since the moving trajectory of the L-shaped connecting frame 510 is elliptical, it cooperates with the connecting rod 535 and the guide plate 534 to drive the rotating rod 532 and the lever 533 to swing back and forth. During the reciprocating swing, the lever 533 can break up the suspended pollutants in front of the dam body 1. When the suspended pollutants accumulate in front of the dam body 1, they may form a dense pollution layer. By breaking up these pollutants, their concentration in a specific area can be significantly reduced, reducing the accumulation phenomenon. Driven by the lever 533, the pollutants suspended in front of the dam body 1 are stirred and dispersed into the surrounding water, thereby reducing the accumulation of pollutants in front of the dam body 1. The broken up suspended pollutants can be discharged along with the conveyor belt 34 and the salvage plate 35, further cleaning the environment.

[0042] Embodiment 2: Combination Figure 3 As shown, on the basis of the first embodiment, a positioning roller 31, a first moving roller 32 and a second moving roller 33 are carefully designed and installed on the structure of the fixed frame 2. The positioning roller 31, the first moving roller 32 and the second moving roller 33 are cleverly arranged at appropriate positions of the fixed frame 2 to ensure that the conveyor belt 34 can be smoothly transmitted. Specifically, the positioning roller 31 is firmly rotatably installed at a specific position of the fixed frame 2 to ensure its stability and accuracy. At the same time, the first moving roller 32 and the second moving roller 33 are flexibly slidably installed on the fixed frame 2 through a fixed seat 39 and a mounting seat 37, respectively, so as to be adjusted as needed;

[0043] In order to drive the entire conveying system, the output end of the driving motor 36 is closely connected and arranged with the positioning roller 31. The operation of the driving motor 36 can be directly transmitted to the positioning roller 31, thereby driving the movement of the entire conveyor belt 34. In addition, the mounting seat 37 and the movable frame 51 are also fixedly connected to ensure the stability and reliability of the movable frame 51 during operation.

[0044] In other parts of the fixed frame 2, a first cylinder 38 and a second cylinder 310 are specially provided. The output end of the first cylinder 38 is connected to the mounting seat 37. Through the telescopic action of the first cylinder 38, the mounting seat 37 can be accurately controlled, thereby affecting the position and angle of the movable frame 51. The output end of the second cylinder 310 is connected to the fixed seat 39. Through the telescopic action, the fixed seat 39 can be accurately controlled, thereby affecting the position and angle of the first movable roller 32 and the second movable roller 33. Such a design not only improves the flexibility of the system, but also enhances the accuracy and reliability of its operation.

[0045] In the embodiment of the present invention, by starting the driving motor 36, the positioning roller 31 is driven to rotate synchronously, and the positioning roller 31 cooperates closely with the first moving roller 32 and the second moving roller 33, and acts on the conveyor belt 34 and the salvage plate 35 together, so that they are coordinated and transmitted. The salvage plate 35 is designed to be multiple, which ensures the continuous and effective salvage of the suspended pollutants at the dam body 1. During the working process, these salvage plates 35 can pick up the suspended pollutants from the water, and transport the picked up suspended pollutants to the second moving roller 33 at the highest point through the transmission of the conveyor belt 34. Subsequently, these suspended pollutants will fall from the second moving roller 33 into the collection frame 54, thereby achieving effective interception and comprehensive salvage of the suspended pollutants.

[0046] At the same time, by activating the first cylinder 38 and the second cylinder 310, in cooperation with the mounting seat 37 and the fixing seat 39, the second movable roller 33 and the first movable roller 32 can be driven to move synchronously. This design enables us to flexibly adjust the initial position of the first movable roller 32. When the water level at the dam body 1 drops, the control system will instruct the first movable roller 32 to move downward to adapt to the change in water level; conversely, when the water level rises, the first movable roller 32 will move upward. Such adjustment ensures that the conveyor belt 34 and the salvage plate 35 can always effectively salvage and collect suspended pollutants, thereby improving the adaptability and salvage efficiency of the entire system.

[0047] How dams used to intercept suspended pollutants in purified water work:

[0048] Step 1: When the suspended pollutants are located at the dam body 1 and need to be treated, the driving motor 36 is turned on to drive the positioning roller 31 to rotate synchronously, and the positioning roller 31 cooperates with the first moving roller 32 and the second moving roller 33 to drive the conveyor belt 34 and the salvage plate 35 to transmit, and the suspended pollutants at the dam body 1 are salvaged by the salvage plate 35;

[0049] Step 2: Turn on the servo motor 511 to drive the cam 512 to rotate synchronously. When the cam 512 rotates, it can drive the L-shaped connecting frame 510 to move to the right, so that the L-shaped connecting frame 510 drives the swing rod 59 and the inclined plate 517 located on the lifting frame 58 to slide to the right, thereby driving the first knocking rod 514 to move to the right, so that the first knocking rod 514 knocks the conveyor belt 34. As the cam 512 rotates, the elastic force of the first damping spring 513 drives the L-shaped connecting frame 510 and the swing rod 59 to move to the left. When the swing rod 59 moves and resets, it can drive the lifting frame 58 located on the cross bar 52 to move up and down, so that the lifting frame 58 drives the second knocking rod 515 and the third knocking rod 516 to move up and down, so that the second knocking rod 515 and the third knocking rod 516 can knock the conveyor belt 34, and the first knocking rod 514, the second knocking rod 515 and the third knocking rod 516 can knock the inner wall of the conveyor belt 34, so that these sticky suspended pollutants are loosened and fall off, thereby achieving the purpose of effective cleaning;

[0050] Step 3: When the inclined plate 517 moves to the right, the inclined plate 517 pushes the protruding rod 529 to move downward, and the protruding rod 529 drives the extension plate 527, the pushing rod 528, and the sliding plate 525 to move downward and compress the third damping spring 526. When the pushing rod 528 moves downward, the pushing groove 523 pushes the connecting plate 522, the sliding plate 520, and the sliding plate 525 to move to the right. When the sliding plate 520 is located on the fixed rod 519 and slides to the right, it compresses the second damping spring 521, and at the same time, the pressing plate 55 is located in the collection frame 54 and moves to the right. When the inclined plate 517 moves to the left, the sliding plate 525, the extension plate 527, the push rod 528 and the protruding rod 529 are driven to move upward and reset under the elastic force of the third damping spring 526. At the same time, the pressing plate 55, the sliding plate 520 and the connecting plate 522 are driven to move and reset under the elastic force of the second damping spring 521. In this way, the pressing plate 55 is driven to extrude and shape the suspended pollutants.

[0051] Step 4: When the L-shaped connecting frame 510 moves back and forth, it drives the connecting rod 535 to move back and forth. Since the moving trajectory of the L-shaped connecting frame 510 is elliptical, the L-shaped connecting frame 510 cooperates with the connecting rod 535 and the guide plate 534 to drive the rotating rod 532 and the lever 533 to swing back and forth. Therefore, during the reciprocating swing process, the lever 533 can break up the suspended pollutants in front of the dam body 1, and the broken up suspended pollutants can be discharged along with the conveyor belt 34 and the salvage plate 35.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
