Description

Technical Field

[0001] The utility model belongs to the technical field of river channel regulation, and specifically relates to a river channel silting device. Background Art

[0002] The prior art discloses a river channel management and silt removal device (CN219386449U), which solves the problem that the current direct suction of silt easily causes pipe blockage. The device comprises a base, wherein the bottom of the base is fixedly installed with support legs near the four corners, the bottom of the support legs is fixedly installed with universal wheels, the bottom of the base is installed with a fixing mechanism, the fixing mechanism is connected to the support legs, the top of the base is fixedly installed with a silt storage cylinder, and the left side of the silt storage cylinder is fixedly installed with a connecting pipe.

[0003] After searching, it was found that the device uses a fixing mechanism to fix the entire device, but in this process it did not take into account that the silt in the river channel itself is soft in texture, and objects above the silt are prone to sinking, while the bottom of the fixing mechanism of the device is a narrow block. This causes the device to easily sink due to the texture of the silt when in use, thereby causing instability of the device; in addition, the pulley structure used at the bottom of the fixing mechanism of the device is not equipped with protective measures during use, which causes the device to be easily blocked by the silt after entering the silt, which not only affects the overall cleanliness of the device, but also brings difficulties to the movement of the device.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0025] A river channel desilting device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, it includes a bottom plate 10, and a tidying structure for controlling movement is arranged inside the bottom plate 10, and the tidying structure includes a slot box 12, a slide plate 14, a sliding bracket 18, a positive and negative screw rod 22 and a block 24. The slot box 12 is fixedly connected to the top of the bottom plate 10, the positive and negative screw rod 22 is rotatably connected to the slot box 12 and is threadedly connected to the block 24, the slide plate 14 is fixedly connected to the bottom of the bottom plate 10, the sliding bracket 18 is slidably connected to the bottom plate 10 and the slide plate 14, and the block 24 is slidably connected to the bottom plate 10; as shown Figure 1 and Figure 2 As shown, a square box 11 for placing a pump body and a sludge storage cylinder is fixedly connected to the top of the bottom plate 10, and a slide plate 14 is composed of two M-shaped blocks of the same shape and size, and a parallel gap is formed between the two M-shaped blocks. The bottom of the M-shaped block is a plane, and the two ends of the plane are set as curved surfaces. The slide plates 14 are symmetrically arranged in two groups, which are respectively located on both sides of the bottom of the bottom plate 10, and sliding holes 16 are opened on the top of the bottom plate 10 near the four corners.

[0026] The working principle is as follows: the interior of the square box 11 is a square cavity, which is used to fix the pump body and the silt storage cylinder, and also to prevent the pump body and the silt storage cylinder from slipping and falling into the river channel during the dredging process. In addition, six square columns are connected to the bottom of the base plate 10, and an arc plate is connected to the bottom of every three square columns. The arc plate and the three square columns form an M-shaped block. The bottom plane of the arc plate is relatively wide, which can effectively increase the contact area between the device and the silt, thereby avoiding the possibility of the device sinking, and the curved surfaces at both ends of the arc plate can effectively buffer the influence of the texture of the silt on the device, thereby stabilizing the entire device. Every two M-shaped blocks form a slide plate 14, and two slide plates 14 are symmetrically arranged at the bottom of the base plate 10. There is a parallel gap between every two M-shaped blocks, and the distance between the two M-shaped blocks is equal to the width of the slide hole 16. The slide hole 16 is a square through-cavity structure, and the four slide holes 16 are respectively arranged directly above the gap between the two groups of slide plates 14.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, top blocks 15 are symmetrically arranged above the bottom plate 10, and the two top blocks 15 are respectively located on both sides of the square box 11, and two slot boxes 12 are symmetrically arranged, and the two slot boxes 12 are located directly above the two top blocks 15. A box door 13 is hinged above the slot box 12 through a hinge, and a square slide is provided inside the slot box 12, and sliding grooves 26 are respectively provided on both sides of the inside of the square slide, and the two sliding grooves 26 and the square slide form a T-shaped slide, and the blocking block 24 is a T-shaped block, and the slot box 12 is slidably connected to the blocking block 24 through the T-shaped slide; as shown in FIG. Figure 4 and Figure 5As shown, a square block is welded in the middle of the square slideway of the slot box 12, and a clamping slot 25 is opened at both ends of the T-shaped slideway. The clamping slot 25 is located directly above the slide hole 16. A motor 23 is arranged on one side of one of the square blocks close to the clamping slot 25. The square block is rotatably connected with a positive and negative screw rod 22. The output end of the motor 23 is connected to one end of the positive and negative screw rod 22. A square slider with a width less than or equal to the width of the square slideway is arranged above the end of the block 24 close to the square block. The positive and negative screw rod 22 is threadedly connected to the square slider, and the square slider slides in the square slideway; as shown in FIG. Figure 1 , Figure 2 and Figure 4 As shown, the top of the sliding bracket 18 is hinged with a movable block 19 through a small hinge. Two movable blocks 19 are provided, which are respectively arranged on both sides above the sliding bracket 18. The sliding bracket 18 and the movable block 19 slide in the sliding hole 16. The two movable blocks 19 clamp and lock the sliding bracket 18 through the clamping groove 25. The blocking block 24 slides in the sliding groove 26 and limits the movable block 19.

[0028] The working principle is as follows: the width of the square slide is greater than or equal to the width of the top block 15; the top block 15 is a square long strip; the slot box 12 is clamped to the top block 15 through the square slide; the square block is located on the top surface of the slot box 12 and is arranged in the square slide; two square blocks are symmetrically arranged; the clamping groove 25 and the square slide together form an H-shaped slide; the maximum length of the clamping groove 25 is the length of the sliding bracket 18 plus the height of the two movable blocks 19; the sliding bracket 18 is a cube as a whole; the movable block 19 is a rectangular parallelepiped as a whole; the length and width of the sliding bracket 18 are less than or equal to the length and width of the sliding hole 16; the sliding bracket 18 slides in the sliding hole 16; the width of the movable block 19 is half of the width of the sliding bracket 18; the length of the movable block 19 is less than or equal to the length of the sliding bracket 18; the height of the movable block 19 is less than or equal to the length or width of the top block 15 When the forward and reverse screw rods 22 rotate, the blocks 24 at both ends will start to move. Since a through hole with the same diameter as the rotating hole is provided in the square slider above the block 24, a circular ring is provided in the through hole, and a thread is provided inside the circular ring, the blocks 24 at both ends can move on the forward and reverse screw rods 22 with the help of the thread, so as to slide from the outside to the inside in the T-shaped slideway. At this time, the space of the clamping groove 25 is released, opposite to the sliding hole 16. At this time, the sliding bracket 18 can slide in the sliding hole 16 by pressing the bottom plate 10.

[0029] like Figure 2As shown, sliders 20 are provided on both sides of the sliding bracket 18, and the sliders 20 are trapezoidal. The inner sides of the two M-shaped blocks of the slide plate 14 are provided with slide grooves 17. The shape of the slide groove 17 is the same as that of the slider 20. The slider 20 slides in the slide groove 17, and the bottom of the sliding bracket 18 is rotatably connected to a pulley 21; Figure 2 As shown, the bottom of the sliding bracket 18 is semicircular, and a circular hole is opened at the center of the bottom of the sliding bracket 18. A shaft column is rotatably connected in the circular hole, and a rotatable shaft ring is set on the central curved surface of the shaft column. The shaft column is rotatably connected to the pulley 21 through the shaft ring.

[0030] The specific implementation is as follows. When using the device, first ensure the environment in which the device is located. If it is on the ground and the device needs to be moved, it is necessary to find stones or use a jack to lift the bottom plate 10 so that the slide plate 14 is higher than the ground, and then start the motor 23 to drive the forward and reverse screw rods 22 to rotate, so that the blocks 24 at both ends move inward. When the two blocks 24 abut against each other, lift the movable block 19 on the sliding bracket 18 upward to make the two movable blocks 19 above the sliding bracket 18 form a vertical state, and then push the top of the movable block 19 to push the sliding bracket 18 to slide in the sliding hole 16 and the slide plate 14. When it slides to the lowest end of the slide groove 17, it stops moving, and the motor is started in the reverse direction. 23, the motor 23 rotates in the opposite direction, so that the blocks 24 at both ends of the forward and reverse screw rods 22 slide from the inside to the outside in the T-shaped slideway of the trough box 12, and the blocks 24 at both ends stop when they reach the top of the square slideway, and the bottom surfaces of the blocks 24 at both ends are able to support the movable block 19, thereby limiting the movable block 19 and the sliding bracket 18, so that they are firmly fixed in the interval of the slide plate 14. At this time, the pulley 21 connected to the sliding bracket 18 below the rotating contact with the ground, thereby ensuring stable sliding, thereby driving the movement of the device as a whole on the ground; when the device needs to enter the river channel to clean up the silt, first open the box door 13, and then start the motor 23, so that the motor 23 drives the forward and reverse screw rods 22 to rotate, and the blocks 24 at both ends move inward at the same time, As the blocks 24 at both ends slide in the slot box 12, when the blocks 24 at both ends completely reach the top of the top block 15, the top of the movable block 19 loses the pressure, causing the device to fall as a whole. At this time, the sliding bracket 18 and the movable block 19 move up in the sliding hole 16, and the sliders 20 on both sides of the sliding bracket 18 slide to the top of the slide groove 17. The movable block 19 reaches the clamping groove 25, the slide plate 14 contacts the ground, and the pulley 21 enters the interval of the slide plate 14. At this time, the movable block 19 above each sliding bracket 18 is placed horizontally from vertical, and then the motor 23 is started in the reverse direction. In the same operating mode, the forward and reverse screw rods 22 drive the blocks 24 at both ends to move from the inside to the outside along the T-shaped slideway above the top block 15, until the movable block 19 reaches the clamping groove 25. When the device reaches the top of the square slide, it stops. At this time, the blocking blocks 24 at both ends use their bottom surfaces to press the top of the movable block 19, thereby ensuring that the sliding bracket 18 is between the slide plates 14, and the pulley 21 is in a position parallel to the bottom surface of the slide plate 14. At this time, the device is placed in the river channel, and the plane at the bottom of the slide plate 14 can ensure that the device is directly above the silt; the slide plate 14 included in the sorting structure used in the device has a relatively wide bottom surface of the arc plate at the bottom, which can effectively increase the contact area between the device and the silt, thereby avoiding the possibility of the device sinking, and the curved surfaces at both ends of the arc plate can effectively buffer the influence of the texture of the silt on the device, thereby stabilizing the entire device and avoiding the device from sinking;In addition, the square column above the arc plate can effectively shield the sliding bracket 18 and the pulley 21, providing protection for them. At the same time, due to the positioning relationship between the movable block 19 and the clamping groove 25, the position of the sliding bracket 18 can be controlled, thereby ensuring the free movement of the pulley 21. When the positive and negative screw rods 22 and the blocking block 24 slide from inside to outside or from outside to inside at the same time, the position of the movable block 19 is limited by the bottom surface of the blocking block 24, which can effectively ensure the free retraction of the sliding bracket 18 and the pulley 21, so as to prevent the silt from clogging the pulley 21 and causing difficulty in movement after the device enters the silt. The flexible retraction can facilitate the cleaning of dirt and effectively ensure the overall cleanliness. ;
