Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a device for cleaning silt from water channels. Background Technology

[0002] A canal is an artificial or natural channel used to transport water. Its main function is to transport water from water sources to farmland to meet the needs of crop growth, while also draining excess water from farmland, cities or industrial areas to prevent flooding and waterlogging.

[0003] After a period of use, silt carried in the water accumulates on the side walls of irrigation canals, affecting the water flow rate. Therefore, it is necessary to clean the silt accumulated on the side walls of the canals. The existing cleaning method is mostly manual removal of silt using tools such as shovels. However, this method is not effective for narrower canals because the limited width results in a small working space. Utility Model Content

[0004] The purpose of this invention is to provide a silt removal device for narrow water channels that can remove silt from the side walls.

[0005] The technical solution of this utility model is: a water channel silt cleaning device, including a support frame, two scrapers slidably installed on the support frame, an adjustment mechanism for driving the two scrapers to move towards or away from each other, and a limiting mechanism for limiting the position between the two scrapers. The upper end of the scraper is connected to the adjustment mechanism, the scraper extends downward from the support frame, the lower end of the scraper is connected to a material receiving device, and a scraper head is vertically provided on the side of the two scrapers that are far apart from each other.

[0006] In the above scheme, by designing two scrapers that move in opposite directions or away from each other, it is possible to make adaptive adjustments according to the width of the water channel, making it suitable for water channels of various widths.

One end of the adjusting handle extends into the mounting cavity and is connected to the inner bottom surface of the mounting cavity via the spring rod. The other end of the adjusting handle protrudes from the limiting mechanism. When the adjusting handle extends axially, the spring rod lengthens, the limiting mechanism is in the unlocked position, and the adjusting handle drives the double-ended screw to rotate. When the adjusting handle retracts axially, the spring rod resets, and the limiting mechanism is in the locked position.

[0009] Preferably, a key is installed between the adjusting handle and the double-ended screw.

[0010] Preferably, the limiting mechanism includes a locking block, a connecting frame connected to the support frame, and a locking frame disposed on one side of the support frame via the connecting frame. The locking frame has a locking groove that extends through the axial direction of the adjusting handle. The locking block is installed on the adjusting handle.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0026] like Figure 1 As shown, the silt removal device for water channels provided in this embodiment includes a support frame 1, a scraper 2, an adjustment mechanism 3, a limiting mechanism 4, an elastic cloth 5, a receiving device 6, and a connecting plate 7.

[0027] One end of the support frame 1 is provided with a port 13 that can be connected to a mobile vehicle, allowing the entire cleaning device to be moved along the water channel by the mobile vehicle. The other end of the support frame 1 is provided with a vertically penetrating groove 11. The groove 11 extends along the length of the support frame 1. At each end of the extension direction of the groove 11, a mounting seat 12 is provided, and the mounting seat 12 is connected to the upper surface of the support frame 1.

[0028] Two scraper blades 2 are provided. The upper ends of the two scraper blades 2 pass through the chute 11, and the lower ends extend vertically downward and are connected to the receiving device 6. A scraper head 21 is vertically provided on the side of the two scraper blades 2 that is far apart from each other. The cross-section of the scraper blade 2 is a gradually decreasing variable cross-section structure, with the end with the smaller area forming the scraper head 21. The small cross-section scraper head 21 can effectively scrape off the silt on the side wall of the water channel, while the large cross-section scraper blade 2 can ensure a stable scraping force output from the scraper head 21. The upper end of the scraper blade 2 is provided with a threaded hole, and the spiral direction of the threaded holes of the two scraper blades 2 is opposite. In order to ensure that the scraper blade 2 has sufficient adjustment stroke, no scraper head 21 is provided on the scraper blade 2 in the chute 11.

[0029] like Figure 1 , Figure 3 As shown, the adjusting mechanism 3 includes a double-ended screw 31, an adjusting handle 32, and a spring rod 33. Both ends of the double-ended screw 31 are rotatably connected to the mounting base 12 of the support frame 1 via bearings. The threaded holes on the two scrapers 2 are threaded onto the two sections of the double-ended screw 31. One end of the double-ended screw 31 has a mounting cavity 311. One end of the adjusting handle 32 extends into the mounting cavity 311 and is connected to the inner bottom surface of the mounting cavity 311 via the spring rod 33. The other end of the adjusting handle 32 protrudes from the limiting mechanism 4 and has a handle 34 at its end. A key (not shown) is installed between the adjusting handle 32 and the double-ended screw 31. The key transmits the torque of the adjusting handle 32 to the double-ended screw 31, enabling them to rotate together.

[0030] like Figure 1 , Figure 3 As shown, the limiting mechanism 4 includes a locking block 43, a connecting frame 41 connected to the support frame 1, and a locking frame 42 disposed on one side of the support frame 1 via the connecting frame 41. The locking frame 42 has a locking groove 421 that extends through the axial direction of the adjusting handle 32. The locking block 43 is mounted on the adjusting handle 32. The locking groove 421 is triangular or polygonal, and the shape of the locking block 43 is the same as that of the locking groove 421.

[0031] In use, pulling the handle 34 extends the adjusting handle 32 axially, stretches the spring rod 33, and puts the limiting mechanism 4 in the unlocked position. The locking block 43 disengages from the locking frame 42. Rotating the handle 34 then causes the adjusting handle 32 to drive the double-headed screw 31 to rotate, thereby adjusting the relative position between the two scrapers 2 until the scraper head 21 contacts the side wall of the water channel. Pushing the handle 34 inward further causes the locking block 43 to engage in the locking groove 421. When the adjusting handle 32 retracts axially, the spring rod 33 returns to its original position, and the limiting mechanism 4 is in the locked position, thus limiting the adjusted position between the two scrapers 2.

[0032] like Figure 1 , Figure 2 As shown, the elastic fabric 5 is connected to the connecting plates 7 at both ends. The connecting plates 7 at both ends are respectively connected to the two scrapers 2. The elastic fabric 5 is a conventional fabric that can be elastically stretched or retracted. Each connecting plate 7 has a support rod 71 connected to one side surface, located within the elastic fabric 5. At least two support rods 71 ​​are arranged circumferentially along the connecting plate 7. The support rods 71 ​​can support the loosened elastic fabric 5 after retraction, preventing the loose elastic fabric 5 from entering the hole of the mounting base 12 as the double-ended screw 31 rotates.

[0033] The receiving device 6 includes a first tray 61 connected to the lower end of one of the scrapers 2, a second tray 62 connected to the lower end of another scraper 2, a third tray 63 horizontally connected to the end side of the first tray 61, and a fourth tray 64 horizontally connected to the end side of the second tray 62. The end of the third tray 63 away from the first tray 61 is extended and retracted in the fourth tray 64.

[0034] The third tray 63 includes a first base plate 632 and a first filter screen 631 connected to both ends of the first base plate 632, i.e., the first filter screen 631 forms the sidewall of the third tray 63. The fourth tray 64 includes a second base plate 642 and a second filter screen 641 connected to both ends of the second base plate 642, i.e., the second filter screen 641 forms the sidewall of the fourth tray 64. The telescopic mechanism of the third tray 63 and the fourth tray 64 can be as follows: the second filter screen 641 and the second base plate 642 are provided with sliding grooves, so that the second filter screen 641 and the second base plate 642 form a hollow structure, and the sliding grooves of the second filter screen 641 and the second base plate 642 are connected at an angle. Alternatively, the top of the inner surface of the second filter screen 641 is provided with a sliding groove, and in cross-section, the sliding groove and the second base plate 642 form a C-shape. Alternatively, other sliding groove structures can be used. One end of the first filter screen 631 and the first base plate 632 is telescopically adapted to fit in the sliding groove. When the scraper 2 adjusts the spacing, it causes the third tray 63 to slide relative to the fourth tray 64.

[0035] Most of the sludge scraped off by scraper 2 falls into the first tray 61 and the second tray 62. As the sludge increases, it moves towards the center and eventually accumulates in the third tray 63 and the fourth tray 64, where it is drained through the first filter screen 631 and the second filter screen 641.

[0036] When sludge needs to be cleaned, stop the vehicle, remove the cleaning device from the vehicle, and pour the sludge from the receiving device 6 into the designated location. Then, reinstall the cleaning device as needed.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
