Description

Technical Field

[0001] The invention relates to the technical field of sand-trapping equipment, and in particular to a sand-trapping device for soil and water conservation in a small watershed. Background Art

[0002] Small watersheds usually refer to closed catchment areas with a small area formed by the watershed and the outlet section, and their drainage area generally does not exceed 50 square kilometers. The problem of soil and water erosion in small watersheds is more prominent, mainly manifested in the destruction of water and soil resources, the deterioration of the ecological environment, and the impact on agricultural production and people's lives. Soil and water erosion will not only lead to poor land and reduced crop yields, but also cause siltation in rivers and reservoirs, reduce the benefits of water conservancy projects, and increase the frequency and intensity of floods and waterlogging disasters. Therefore, it is of great practical significance to carry out soil and water conservation management in small watersheds.

[0003] Chinese patent publication number CN118292396B discloses a small watershed soil and water conservation sand-trapping device, comprising a base and a support plate fixed to the base, elastic telescopic rods fixed to the left and right sides of the front side of the support plate, and sand-proof plates for blocking mud and sand in the wind fixed between the ends of the elastic telescopic rods.

[0004] However, the existing small watershed soil and water conservation sediment-trapping devices have some obvious defects. First, these devices usually require frequent manual maintenance. Since the sediment-trapping devices are in an underwater environment for a long time, they are easily eroded by water flow and worn by sediment, which causes the structure and function of the device to be gradually damaged. For example, the sediment-trapping net or dam may be damaged, deformed or blocked, and needs to be inspected and repaired regularly, which not only increases the maintenance cost, but also affects the normal operation of the device;

[0005] Secondly, most of the existing sand traps cannot achieve self-cleaning or have poor self-cleaning effects. In actual use, sediment will accumulate on the surface of the sand trap, forming a thick layer of sediment, which affects the sand trapping effect of the device. Although some devices use simple flushing or vibration devices to achieve self-cleaning, these methods are often ineffective and cannot completely remove the accumulated sediment, resulting in a gradual decrease in the sand trapping efficiency of the device.

The present invention utilizes a sand-trapping net installed in a rotating frame to intercept the sand and soil flowing at the bottom of the river channel and keep it in the upstream area of ​​the equipment. Furthermore, when the flow speed of the water area slows down, the installation frame is driven to rise through the action of the lifting groove on the supporting structure, thereby driving the rotating frame to rise. The rotating frame is driven to rotate by a motor seat arranged on the upper part of the installation frame, and its interception surface is in the water-facing direction.

The present invention drives a roller to slide upward in a lifting groove through the cooperation of a winding motor and a cable, thereby driving the installation frame and the rotating frame to move upward. During this process, the T-block is separated from the outer frame of the rotating frame, thereby releasing the limit on the rotating frame. The rotating frame is driven to rotate by a rotating motor in the motor seat, and the self-locking component is locked by the cooperation of the self-locking component and the locking hole during the rotation process, so as to prevent the installation frame from falling during the rotation and cleaning process and causing the rotating frame to be stuck or damaged.

[0024] 3. The present invention utilizes the action of winding motor 2 and cable 2 to drive the self-cleaning component to slide in slide groove 2, and drives the cleaning brush to rotate through the cooperation of rack and gear, and cleans the surface of the sand-trapping net through the bristles on the surface of the cleaning brush to clean the sand and gravel, algae and garbage attached to the surface that are blocked in the pores of the sand-trapping net, and the impact of water flow makes them fall off the surface of the sand-trapping net, thereby realizing automatic cleaning of the sand-trapping net, improving the service life and service life, and reducing the frequency of manual maintenance.

[0025] 4.

DETAILED DESCRIPTION

[0038] 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.

[0039] Embodiment 1, as Figure 1As shown, a small watershed soil and water conservation sediment trap device comprises a mounting seat 1, an outer frame structure 3 is fixedly connected to the middle of the upper end of the mounting seat 1, a plurality of anchor holes 2 are symmetrically opened along the outer frame structure 3 at the upper end of the mounting seat 1, a support structure 4 is arranged on the inner surface of the outer frame structure 3, and a sediment trap structure 5 is arranged on the inner surface of the support structure 4;

[0040] like Figure 2 and Figure 4 As shown, the outer frame structure 3 includes a support frame 31, and the inner surface of the support frame 31 is symmetrically provided with lifting grooves 32 that are slidably connected to the support structure 4, and the inner surfaces of the lifting grooves 32 on both sides are fixedly connected with T-shaped blocks 36;

[0041] like Figure 2 and Figure 5 As shown, the support structure 4 includes a mounting frame 41 slidably connected to the inner surface of the lifting groove 32, and a self-locking component 47 fixedly connected to the sand retaining structure 5 is provided at the lower end of the mounting frame 41;

[0042] like Figure 3 As shown, the sand retaining structure 5 includes a rotating frame 51 rotatably connected to the inner surface of the mounting frame 41 , a sand retaining net 55 is fixedly mounted on the inner surface of the rotating frame 51 , and a self-cleaning component 56 is arranged at the rear of the inner surface of the rotating frame 51 .

[0043] The anchor holes 2 are mainly used to fix the mounting base 1 to the riverbed through anchor bolts. The two sides of the outer frame structure 3 are fitted with both sides of the river channel, and the irregular gaps are filled with sandbags and cement to ensure that the water flow and the sediment it carries are within the range of 55;

[0044] Since the silt is heavy, even if it is washed up by the water flow, it will be in the lower layer of the water flow, especially in small water areas where the water flow is not very strong, so the equipment can be installed at the bottom of the river.

[0045] During the operation of this embodiment, the sand-trapping net 55 installed in the rotating frame 51 is used to intercept the sand and soil flowing at the bottom of the river channel and keep it in the upstream area of ​​the equipment. Furthermore, when the flow speed of the water area slows down, the lifting groove 32 acts on the supporting structure 4 to drive the installation frame 41 to rise, and then drives the rotating frame 51 to rise. The motor base 45 set on the upper part of the installation frame 41 drives the rotating frame 51 to rotate, and its interception surface is in the water-facing direction, and its interception surface is cleaned by the self-cleaning component 56, so that the blocked sand and debris are separated under the impact of the water flow, thereby ensuring the water flow efficiency and sand interception efficiency of the sand-trapping net 55.

[0046] Embodiment 2. Based on embodiment 1, this embodiment drives roller 42 to slide upward in lifting groove 32 through the cooperation of winding motor 33 and cable 34, thereby driving installation frame 41 and rotating frame 51 to move upward. During this process, T-block 36 is separated from the outer frame of rotating frame 51, thereby releasing the limit on rotating frame 51, and rotating frame 51 is driven to rotate by rotating motor 451 in motor seat 45. During the rotation, self-locking component 47 is locked through the cooperation of locking hole 37 to prevent installation frame 41 from falling during rotation and cleaning, causing rotating frame 51 to get stuck or damaged. Sand retaining net 55 is flushed and cleaned by water recoil, thereby realizing automatic cleaning of sand retaining net 55, improving service life, extending maintenance cycle and reducing maintenance cost.

[0047] Specifically, in order to achieve the lifting of the rotating frame 51 and thus achieve self-cleaning, refer to Figure 2 , Figure 4 , Figure 5 and Figure 6 The upper end of the mounting frame 41 is symmetrically provided with limiting grooves 43 that are adapted to the shape of the T-shaped block 36 and are slidably connected to the outer surface of the T-shaped block 36. The inner surface of the mounting frame 41 is rectangularly distributed and fixedly connected with four rubber strips 44 that are tightly attached to the outer surface of the rotating frame 51. The left and right ends of the mounting frame 41 are symmetrically fixedly connected with rollers 42 that are slidably connected to the inner surface of the adjacent lifting groove 32. A motor seat 45 is fixedly installed on the upper end of the mounting frame 41, and a rotating motor 451 that is transmission-connected to the rotating frame 51 is fixedly installed on the inner surface of the motor seat 45.

[0048] The T-shaped block 36 can slide in the limiting groove 43 and is located at the uppermost side of the lifting groove 32. When the rotating frame 51 is located within the range of the lifting groove 32, the T-shaped block 36 is always in close contact with the side wall of the rotating frame 51. When the rotating frame 51 is located at the uppermost part, the T-shaped block 36 does not contact the side wall of the rotating frame 51.

[0049] Therefore, when the rotating frame 51 is inside the support frame 31, it cannot rotate, which also avoids accidental rotation caused by water impact, sand and stone collision or aquatic creature impact.

[0050] Only when the winding motor 33 and the cable 34 drive the roller 42 to be lifted to the uppermost side, the bottom edge of the rotating frame 51 exceeds the upper end of the support frame 31, the T-shaped block 36 is separated from the rotating frame 51, and only the rubber strips 44 on both sides of the rotating frame 51 are attached to it, and the rotating motor 451 inside the motor seat 45 can drive the rotating frame 51 and the self-locking component 47 to rotate, thereby rotating the original water-facing surface of the sand-trapping net 55 to the water-receiving surface, thereby realizing backwashing of the sand-trapping net 55.

[0051] Further, to achieve the improvement of the installation frame 41, refer to Figure 5A winding motor 33 is fixedly installed in the inner cavity of the mounting seat 1, and two cables 34 are connected to the output end of the winding motor 33 through winding reels. The two cables 34 are wound in opposite directions and their ends away from the winding motor 33 extend to the inner surfaces of adjacent lifting grooves 32 and are fixedly connected with slip rings 35. The two slip rings 35 are respectively rotatably connected to the outer surfaces of adjacent rollers 42, and locking holes 37 compatible with the self-locking components 47 are opened on the upper sides of the inner walls of the lifting grooves 32 on both sides.

[0052] The winding motor 33 drives the winding drum to rotate, and the cable 34 is wound on the winding drum. Further, the cable 34 pulls the slip ring 35 to drive the roller 42 to rise in the lifting groove 32, thereby driving the installation frame 41 to move upward.

[0053] When resetting is required, the winding motor 33 is reversed, the cable 34 is released, and the cable 34 no longer provides traction to the slip ring 35 and the roller 42. Under the action of gravity, the installation frame 41 will fall downward and prompt the installation frame 41 to return to the inner side of the support frame 31 along the lifting groove 32 to complete the resetting.

[0054] Further, in order to lock the mounting frame 41 during the self-cleaning process to avoid damage to the equipment, refer to Figure 7 and Figure 8 A mounting groove 411 is provided at the lower end of the mounting frame 41, and cavities 474 are symmetrically provided on both sides of the inner surface of the mounting groove 411, and cavities 472 are symmetrically provided on both sides of the outer surface of the mounting frame 41. A connecting pipe 473 connected with the adjacent cavity 1 472 is provided on the side of several cavities 474 away from the mounting groove 411, and the inner surfaces of cavity 1 472, connecting pipe 473 and cavity 2 474 are all filled with hydraulic oil.

[0055] Further, in order to follow the rotation of the rotating frame 51 and lock the mounting frame 41 to a predetermined height, see Figure 7 , Figure 8 and Fig. 9The self-locking assembly 47 includes a limit plate 475 fixedly connected to the lower end of the rotating frame 51 and rotatably connected to the lower end of the mounting frame 41. The outer surface of the limit plate 475 is located on the inner surface of the mounting groove 411 and is fixedly connected to a staggered chuck 476. The inner surface of the mounting groove 411 is symmetrically slidably connected to a sliding plate 477 that is tightly attached to the outer surface of the staggered chuck 476. The two sliding plates 477 are symmetrically fixedly connected to the adjacent cavity two on one side away from the staggered chuck 476. The piston rod 478 is slidably connected to the inner surface of 474, and the two sliding plates 477 are fixedly connected to the side away from the staggered chuck 476 with a spring 479 fixedly connected to the inner wall of the mounting groove 411, and the inner surfaces of the plurality of cavities 472 are slidably connected to the locking bolts 471; the staggered chuck 476 is respectively provided with M-shaped notches on the left upper end and the right lower end, and the sliding plates 477 on both sides are staggeredly fixed with semicircular plates that fit with the adjacent M-shaped notches on the side close to the staggered chuck 476.

[0056] When the rotating frame 51 is turned over by the rotating motor 451, the limiting plate 1 475 will be driven to move synchronously. When the limiting plate 1 475 rotates, the staggered chuck 476 rotates synchronously. At this time, the sliding plate 477 will slide in the installation groove 411 following the rotation of the staggered chuck 476, and push the sliding plate 477 away from the staggered chuck 476. At this time, the piston rod 478 installed on the sliding plate 477 will squeeze the hydraulic oil in the cavity 2 474 and make it enter the cavity 1 472 along the connecting pipe 473, thereby pushing the locking bolt 471 to extend from the cavity 1 472 and enter the locking hole 37;

[0057] When the rotating frame 51 is reset, the staggered chuck 476 rotates and resets following the limit plate 1 475, and the sliding plate 477 follows the staggered chuck 476 to reset under the action of the spring 1 479, thereby drawing the hydraulic oil in the cavity 1 472 back to the cavity 2 474 through the connecting pipe 473 through the piston rod 478, and prompting the locking bolt 471 to return to the inside of the cavity 1 472 to release the limit.

[0058] Embodiment 3. Based on embodiment 2, this embodiment further utilizes the action of winding motor 2 52 and cable 2 53 to drive self-cleaning component 56 to slide in slide groove 2 54, and drives cleaning brush 564 to rotate through the cooperation of rack 541 and gear 562. The bristles on the surface of cleaning brush 564 clean the surface of sand retaining net 55, and the sand, gravel, algae and garbage attached to the surface that are blocked in the pores of sand retaining net 55 are cleaned, and the impact of water flow makes them fall off the surface of sand retaining net 55, thereby realizing automatic cleaning of sand retaining net 55, improving the service life and service life, and reducing the frequency of manual maintenance.

[0059] Specifically, in order to drive the self-cleaning component 56 to clean the sand trap 55, refer to Figure 3The inner surface of the rotating frame 51 located at the rear side of the sand-trapping net 55 is symmetrically provided with slide grooves 54 up and down, and a winding motor 52 is fixedly installed on the upper side of the inner surface of the rotating frame 51. The output end of the winding motor 52 is connected to two cables 53 through a winding reel. The two cables 53 extend to the inner surface of the slide groove 54 located at the upper part away from the winding motor 52 and are fixedly connected to the self-cleaning component 56.

[0060] The operation mode of the winding motor 2 52 and the cable 2 53 is basically the same as that of the winding motor 1 33 and the cable 1 34. It is mainly used to guide the roller 2 563 to move in different directions in the slide 2 54 by tightening or loosening the cable 2 53 through the winding disk, so as to circulate and clean the surface of the sand-trapping net 55.

[0061] Further, in order to clean the surface of the sand trap 55, refer to Fig.10 The self-cleaning component 56 includes a roller 563 that is slidably connected to the inner surface of the upper slide groove 54, a slip ring 561 that is rotatably connected to the upper part of the outer surface of the roller 563 and is fixedly connected to the cables 53 on both sides, a gear 562 is fixedly connected to the middle part of the outer surface of the roller 563, a rack 541 that meshes with the gear 562 is fixedly connected to the inner surface of the slide groove 54, and a cleaning brush 564 that fits the outer surface of the sand retaining net 55 is fixedly connected to the lower end of the roller 563.

[0062] When roller 2 563 moves in upper slide groove 2 54 under the action of slip ring 2 561 and cable 2 53, the gear 562 installed on its outer surface meshes with the rack 541, which can drive roller 2 563 to rotate, and then drive the cleaning brush 564 to rotate. The cleaning brush 564 can clean the surface and pores of the sand-trapping net 55 during the rotation process, and cooperate with the impact of water flow to clean up some debris such as sand, debris, and aquatic plants.

[0063] Embodiment 4: Based on embodiment 3, this embodiment utilizes the cooperation between the corrugated groove 542 and the linkage column 566 to drive the impact hammer 569 to move in a wave-shaped trajectory, and then strikes the sand-trapping net 55 inside the rotating frame 51 on the inner surface of the slide groove 2 54, causing the particles in the pores to fall off, thereby further improving the cleaning effect of the cleaning brush 564.

[0064] Specifically, the auxiliary cleaning brush 564 cleans the sand trap 55 to remove the sand and gravel stuck therein. Fig.11A corrugated groove 542 is provided on the bottom wall of the inner surface of the lower slide groove 54. The lower end of the cleaning brush 564 is rotatably connected to a slider 565 which is slidably connected to the lower slide groove 54. The lower end of the slider 565 is slidably connected to a hammer 569 which is slidably connected to the inner surface of the corrugated groove 542 through a C-shaped ring. A linkage column 566 is fixedly connected to the lower part of the outer surface of the hammer 569. The rear end of the hammer 569 is fixedly connected to a limiting plate 567. The front end of the limiting plate 567 is fixedly connected to a spring 568 which is fixedly connected to the C-shaped ring.

[0065] When the cleaning brush 564 moves left and right, the slider 565 will be driven to slide in the cleaning brush 564 on the lower side, thereby driving the impact hammer 569 to move horizontally in the cleaning brush 564. When the impact hammer 569 moves left and right, the linkage column 566 will also move in the corrugated groove 542, thereby driving the linkage column 566 and the impact hammer 569 to move along the trajectory of the corrugated groove 542. Due to the particularity of the trajectory of the corrugated groove 542, the impact hammer 569 will periodically impact the inner wall of the slide groove 2 54 under the action of the spring 2 568, and transmit the vibration to the sand-trapping net 55 through the slide groove 2 54. Although the vibration will be partially reduced underwater, the tiny vibration can also cause the sand and gravel in the mesh of the sand-trapping net 55 to detach, thereby assisting the cleaning brush 564 to clean the sand-trapping net 55.

[0066] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
