[0020] Embodiment 1, see Figures 1 - 5 、 Figure 9 , a device for preventing and treating river water pollution provided by the invention includes a towing plate 100. First floating cylinders 101 are fixed on both sides of the towing plate 100. An installation block 102 is fixed on the towing plate 100. An installation groove 103 is provided on the top surface of the installation block 102. A movable groove 104 is provided on the bottom surface of the installation groove 103. A collection barrel 105 is arranged in the movable groove 104. A water outlet hole 201 is provided on the bottom surface of the collection barrel. A filtering member is installed in the collection barrel; a support frame is arranged on the top surface of the installation block corresponding to the position of the collection barrel. A motor 201a is fixed on the support frame. The power output end of the motor is connected to a driving rod 201c. The driving rod penetrates through the filtering member and there is a gap between the driving rod and the filtering member, so that the filtering member can move up and down and rotate. A fan blade 201d is installed at the end of the driving rod away from the motor; a driving member capable of controlling the up and down movement of the collection barrel is installed on the support frame or the driving rod; when the collection barrel moves down to the bottom position, the fan blade is located inside the collection barrel; in actual production, the fan blade can be located outside the collection barrel in its original state and enter the collection barrel through the water outlet hole when the collection barrel moves down, or the fan blade can be located inside the collection barrel in its original state and always remain inside the collection barrel when the collection barrel moves down.

[0021] The above support frame can use an existing structure. In this embodiment, the support frame includes reinforcing plates 107 fixed on both sides of the installation groove and a fixing plate 108 connected to the reinforcing plates on both sides. The motor is fixed on the top surface of the fixing plate. The power output end of the motor passes through the fixing plate and is rotationally connected or has a clearance fit with the fixing plate; The above-mentioned driving member can use an existing structure. In this embodiment, the driving member is a pressing rod 204a, and the bottom end of the pressing rod contacts the top surface of the collection bucket; correspondingly, a second floating cylinder 106 is sleeved on the collection cylinder 105. The top surface of the collection bucket is provided with a concave surface 204c and a convex surface 204d. The movable groove is slidably connected to the collection bucket. During manufacturing, a limiting groove 201f for restricting the rotation of the collection bucket can be provided on the inner wall of the movable groove. A limiting block 201e that cooperates with the limiting groove is installed on the collection bucket, and the limiting block is slidably connected to the limiting groove.

[0022] The above-mentioned filtering member can directly use an existing structure such as a filter net. In this embodiment, the filtering member includes an annular sleeve 401b sleeved on the driving rod and a collection frame 401d with a filter net 401e installed on the bottom surface. There are multiple collection frames, which are circumferentially arranged on the annular sleeve; the inner diameter of the annular sleeve is greater than or equal to the diameter of the driving rod; the collection frame is connected to the inner wall of the collection bucket, and the second floating cylinder is connected to the outer wall of the collection bucket. Generally, the second floating cylinder is arranged near the top of the collection bucket, and the collection frame can be arranged near the middle or top of the collection bucket. A collection groove 201b is formed above the filter net inside the collection bucket for accommodating garbage, such as Figure 5 As shown, the collection frame can be formed by an arc-shaped plate and two straight plates. Preferably, the arc-shaped plate and the collection bucket are set in a detachable connection manner to facilitate the cleaning of the collection frame in the future.

[0023] When the river water pollution prevention and treatment device in the first embodiment is in use, the towing plate can be installed on the hull and used. The device is driven by the hull to move, so as to widely suck the garbage in the water. The first floating cylinders on both sides of the towing plate provide buoyancy for the whole device, making it more stable during use; in the original state, under the action of the second floating cylinder, the top surface of the collection bucket floats on the water surface. When the motor runs, it drives the fan blade and the pressing rod to rotate, so that the pressing rod switches through the concave surface and the convex surface of the collection bucket. During the process of switching from the concave surface to the convex surface, the pressing rod gradually presses the collection bucket, causing the collection bucket to move down below the water surface. When the fan blade rotates, it generates a suction force in the collection bucket, causing the garbage on the water surface to enter the collection bucket. During the process of the pressing rod switching from the convex surface to the concave surface, the collection bucket moves up, and the top surface emerges from the water surface, so that the garbage entering the collection bucket remains in the collection bucket. In this way, the collection bucket moves down and up once to complete one collection. During actual manufacturing, the concave surface and the convex surface are smoothly transitioned. One group or multiple groups can be set. Of course, two groups or multiple groups of pressing rods can also be set, which are circumferentially and evenly arranged on the driving rod. No specific limitation is made here.

[0024] Embodiment 2, see Figure 3 、 Figure 4 、 Figures 6 - 8, Embodiment 2 adds an oil absorption structure on the basis of Embodiment 1, aiming to adsorb the oil on the water surface. Specifically, a support plate 301a is fixed on the driving rod, and the top end of the pressing rod is fixedly connected to the support plate; inclined plates 301b are fixedly connected to both sides of the support plate, and an oil absorption cylinder 301c is arranged between the inclined plates on both sides of the fixed plate. One end of the oil absorption cylinder is connected to the inclined plate on one side of the support plate, and the other end is connected to the inclined plate on the other side of the support plate. An oil absorption port 302e is arranged on the oil absorption cylinder, and an oil absorption structure 302 for adsorbing oil stains is arranged in the oil absorption barrel. The oil absorption structure can use the existing structure. The following is the specific structure of the oil absorption structure in this embodiment: See Figure 8 , both ends of the oil absorption cylinder are closed, so that an oil absorption cavity 302a is formed inside the oil absorption cylinder; an auxiliary rod 303e is arranged on the top surface of the oil absorption cylinder, and the bottom end of the auxiliary rod passes through the oil absorption cylinder and is located in the oil absorption cavity. When manufacturing, a hole for the auxiliary rod to pass through can be arranged on the top surface of the oil absorption cylinder, and the diameter of the hole is slightly larger than the outer diameter of the auxiliary rod, so that the auxiliary rod can move up and down after passing through the hole; a control structure for controlling the up and down movement of the auxiliary rod is arranged at the top end of the auxiliary rod; movable plates 302c are arranged at positions on both sides of the auxiliary rod in the oil absorption cavity. The movable plate can be in direct contact with the inner wall of the oil absorption cylinder, or a piston ring can be sleeved on the outside, or a piston can be directly used instead. There is no specific limitation here. The movable plate is slidably connected to the oil absorption cylinder. A wedge-shaped block 302f is fixed on the surface of the movable plate facing the auxiliary rod. The wedge-shaped block includes an inclined surface, and the inclined surface faces the auxiliary rod. A contact plate 303f is arranged at the bottom end of the auxiliary rod, and both ends of the contact plate are in contact with the corresponding inclined surfaces; a tension spring 302g is arranged between the wedge-shaped blocks on both sides of the auxiliary rod, and both ends of the tension spring are connected to the corresponding wedge-shaped block or movable plate; a partition plate 302b is fixed on the side of the movable plate facing away from the auxiliary rod in the oil absorption cavity. An oil absorption cotton 302d is arranged between the partition plate and the movable plate. A oil storage chamber is formed on the side of the partition plate facing away from the oil absorption cotton, and an oil absorption chamber is formed between the partition plate and the movable plate. The oil absorption port is communicated with the oil absorption chamber and is arranged close to the corresponding movable plate. A communication hole 303h for communicating the oil storage chamber and the oil absorption chamber is arranged at the top of the partition plate; a first air vent hole 302i is arranged on the inclined plate, and a second air vent hole 302h is arranged on the top of the oil absorption cylinder. The second air vent hole is communicated with the oil storage chamber and the first air vent hole respectively; The above control structure can use existing structures. In this embodiment, a connecting plate 202d is fixed on the driving rod, and the connecting plate is located above the support plate; the control structure includes a first cross plate 303c, a second cross plate 303d and a circular plate 304b. The top surface of the circular plate is spherical. The top end of the auxiliary rod is connected to the first cross plate. A movable rod 303b is arranged on the first cross plate at a position corresponding to the inclined plate. A perforation 303a is arranged on the inclined plate at a position corresponding to the corresponding movable rod. The perforation is a through hole penetrating the inclined plate. It is only named perforation for the convenience of distinguishing from communication holes, etc. During production, the shape of the perforation can be circular or square, and the inner diameter or width is greater than the outer diameter of the movable rod; the top end of the movable rod passes through the corresponding perforation and is connected to the bottom surface of the circular plate. The circular plate is located above the connecting plate, and the second cross plate is located below the connecting plate; the second cross plate is fixedly connected to the movable plate, and a return spring 303g is arranged on the second cross plate. One end of the return spring is connected to the connecting plate, and the other end is connected to the second cross plate; a spherical convex 304a that cooperates with the top surface of the circular plate is arranged on the bottom surface of the fixed plate.

[0025] When the river water pollution prevention and treatment device in the above-mentioned second embodiment cleans the garbage on the water surface, the motor drives the support plate, which not only makes the pressing rod rotate, but also makes the inclined plate rotate, and then drives the movable rod to rotate, so that the circular plate rotates relative to the fixed plate 108, so that there is a contact and extrusion process between the top surface of the circular plate and the spherical convex on the bottom surface of the fixed plate. When the top surface of the circular plate contacts and extrudes the spherical convex on the bottom surface of the fixed plate, the movable rod drives the first cross plate and the second cross plate to move downward, and then drives the auxiliary rod to move downward, and the return spring is stretched. When the top surface of the circular plate and the spherical convex on the bottom surface of the fixed plate are separated, under the restoring force of the return spring, it drives the second cross plate, the first cross plate, the movable rod and the auxiliary rod to rise. During the downward and upward movement of the auxiliary rod, it drives the contact plate to relax and squeeze the wedge blocks on both sides to make them relax and squeeze the movable plate. Before squeezing the movable plate, the grease on the water surface enters the oil absorption port and contacts the oil absorption cotton, and is adsorbed by the oil absorption cotton. When the movable plate is squeezed, it squeezes the oil absorption cotton, so that the oil absorption cotton is compressed. During the compression of the oil absorption cotton, the volume of the oil absorption chamber shrinks. The oil absorption port is located outside the oil absorption chamber. Especially when the movable plate is in a sealed state with the oil absorption cylinder, the oil absorption port is no longer communicated with the oil absorption chamber. The grease adsorbed by the oil absorption cotton is squeezed and enters the oil storage chamber through the communication hole. The gas above the oil storage chamber is discharged through the first vent hole and the second vent hole. When the movable plate is relaxed, under the restoring force of the tension spring, the wedge block drives the movable plate to return to its original state, and external air enters the oil storage chamber and the oil absorption chamber through the first vent hole and the second vent hole until the oil absorption port is communicated with the oil absorption chamber again, and so on; During actual production, the oil suction tube is located inside the collection bucket. When the bottom end of the pressing rod contacts the concave surface, its height is slightly lower than the top surface of the second floating cylinder. When the bottom end of the pressing rod contacts the convex surface, its height is slightly higher than the top surface of the second floating cylinder. Of course, the top surface of the convex surface is slightly lower than the top surface of the second floating cylinder. In this way, during the use of the device, when the second floating cylinder drives the collection bucket upward, the water in the collection bucket is discharged through the water outlet hole until it is flush with the water surface. At this time, there is a space above the water surface inside the collection bucket where the second floating cylinder is arranged. During the downward movement of the collection bucket, the fan blades rotate to prevent the water from quickly entering through the lower part of the water outlet hole. When the second floating cylinder is lower than the water surface, water flows into the above space from above the second floating cylinder, driving the garbage into the collection bucket, and then cooperating with the negative pressure suction effect of the fan blades to collect the garbage on the water surface, with better effects.

[0026] It should be noted that Figure 8 the inclined surface of the wedge block in Figure 8 can be such that the bottom end is closer to the movable plate than the top end as shown, or the bottom end can be farther from the movable plate than the top end. The difference is only in that the auxiliary rod moves upward to squeeze the wedge block and the auxiliary rod moves downward to squeeze the wedge block. This is easily obtained by those skilled in the art according to Figure 8 the disclosed structure and will not be elaborated here; the bottom surface of the above fixed plate is also provided with a groove that cooperates with the top surface of the circular plate. Compared with the method of setting a spherical protrusion, the difference is that when the circular plate moves to the groove position, the auxiliary rod moves upward, while when setting a spherical protrusion, when the circular plate moves to the spherical protrusion position, the auxiliary rod moves downward. This is easily obtained by those skilled in the art according to the above structural principle and will not be elaborated here; the top surface of the above circular plate can also be a conical surface, and the bottom surface of the fixed plate is provided with a conical protrusion that cooperates with the top surface of the circular plate. The functions of extrusion and separation are realized through the cooperation of the conical surface and the conical protrusion, as long as the function of driving the auxiliary rod to move up and down to squeeze and relax the wedge block can be realized, and no specific limitation is made here.

[0027] Embodiment 3, see Figures 2 - 4 , Embodiment 3 adds a garbage cleaning structure on the basis of Embodiment 2. Specifically, an installation frame 202a is fixed in the installation groove, and an internal gear ring 202 is fixed on the top surface of the installation frame; one end of the connecting plate that is not connected to the driving rod is connected to a linkage plate 202e, and the linkage plate is also connected to the support plate to increase the firmness of the overall structure. The bottom end of the linkage plate is rotatably connected to a cleaning rod 203a, a gear 203b that meshes with the gear ring is arranged on the cleaning rod, and a cylindrical cleaning block 203c is fixed at the bottom end of the cleaning rod. The cylindrical cleaning block is located outside the second floating cylinder and contacts the outer wall of the second floating cylinder.

[0028] When the structure in the third embodiment above is in use, when the driving rod rotates, it drives the linkage plate to rotate circumferentially. When the linkage plate rotates circumferentially, it drives the cleaning rod to rotate circumferentially. When the cleaning rod rotates circumferentially, the gear and the toothed ring cooperate to make the cleaning rod rotate self - axially, driving the cleaning block to rotate self - axially, so as to clean the floating garbage on the outer wall of the second floating barrel, preventing the floating garbage from accumulating on the outer wall of the second floating barrel and hindering the garbage from entering the collection barrel. Generally, the cylindrical cleaning block is set longer so that it remains in contact with the outer wall of the second floating barrel when the second floating barrel moves up and down. Of course, intermittent contact during the up - and - down movement of the second floating barrel can also achieve the cleaning function, and no specific limitation is made here.

[0029] The usage method of the above - mentioned river water pollution prevention and treatment device is as follows: S1: Connect the device to the hull through the towing plate 100, and drive the device forward by driving the hull. S2: During the movement of the device, the driving rod 201c drives the fan blade 201d to rotate, and through the driving rod and the pressing rod, the collection barrel moves up and down to suck the garbage on the water surface. S3: Clean the garbage inside the collection barrel.

[0030] The above - mentioned is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above - mentioned embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
