Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to a high-efficiency interception device for a water channel in a water conservancy project. Background Art

[0002] In the field of water conservancy projects, canals, as core structures for transporting water resources, generally face the dual challenges of intercepting floating objects and maintaining channels.

[0003] Most existing canal interception devices use a single interception net structure of fixed size, which needs to be customized according to the canal width. When used in canals of different widths or river sections with complex terrain, frequent equipment replacement or on-site modification is required, resulting in high project costs and long construction periods.

[0004] After long-term use, the interception net is prone to accumulate weeds, mud, domestic garbage and other debris, which leads to increased water flow resistance, decreased flow capacity, and even channel blockage or water pollution. The existing technology relies on regular manual salvage or mechanical dredging, which has problems such as high labor intensity, high safety risks, and untimely maintenance.

[0005] Therefore, an efficient interception device for water channels in water conservancy projects is proposed. Summary of the Invention

[0010] Preferably, the ratchet and the ratchet disk are unidirectionally engaged, the shaft rotates unidirectionally at the top of the first interception net, and the symmetrical second interception nets move away from each other when the shaft rotates unidirectionally.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When the horizontal plate is stepped on, the hook-shaped plate moves downward, so that the second interception net is no longer limited and can slide relatively far away from the outer wall of the first interception net, which reduces the difficulty of staff adjusting the equipment, improves the adaptability of the first interception net to channels of different widths, and extends the effective use range of the equipment. The second interception net is driven to slide on the outside of the shaft by the rotation of the shaft, which can effectively avoid the problem of insufficient elastic force of the third spring at the end of elastic extension, resulting in the side wall of the second interception net unable to fit tightly against the side wall of the channel, so that the equipment can maintain the stability of the first interception net in the channel when facing channels of different widths.

[0017] 2. When water flows through the drainage hole and impacts the fan blades, the fan blades drive the rotation of the circular shaft and the round rod, and the slide plate slides back and forth up and down on the outer wall of the round rod, so that the first scraper scrapes and dredges the first interception net in a cycle, thereby reducing the problem that when the first interception net is intercepting in the canal, the water flow is difficult to pass through due to the blockage of a large amount of debris on the first interception net, and reducing the impact of the first interception net on the canal flow rate after the setting of the first interception net. By arranging the first scraper and the second scraper in parallel on the slide plate, the water flow does not impact the first scraper due to the shielding and guidance of the second scraper, thereby forming a relatively stable space between the first scraper and the second scraper in the water, so that the debris scraped off the first interception net will not float around on the slide plate, so that the equipment can clean and collect the debris on the first interception net in the water, and ensure that the first interception net will not cause the problem of slow water flow due to blockage of debris.

[0036] The second interception net 41 fits tightly with the first interception net 1 , and the side wall of the second interception net 41 is provided with an inclined surface.

[0037] The first interception net 1 is provided with a distance adjustment component 5 inside, and the distance adjustment component 5 includes a shaft rod 51 rotatably connected to the top of the first interception net 1, and the outer wall of the shaft rod 51 is symmetrically provided with straight sliding grooves 52, and the two sides of the outer wall of the shaft rod 51 are symmetrically provided with threaded sliding grooves 53, and the straight sliding grooves 52 are connected with the threaded sliding grooves 53. The shaft rod 51 is located on one side of the first interception net 1 and is provided with annular tooth grooves 54 distributed in an annular array. The end of the shaft rod 51 outside the first interception net 1 is fixedly connected with a pull plate 55, and a first spring 57 is symmetrically fixedly connected between the pull plate 55 and the side wall of the first interception net 1. The pull plate 55 is fixedly connected to the first spring 57 on the side close to the first interception net 1. The slide rod 56, the first slide rod 56 is slidably connected to the inside of the first interception net 1, the outer wall of the shaft 51 is fixedly connected to the ratchet disk 58, the outer wall of the first interception net 1 is close to the ratchet disk 58 and is fixedly connected to the ratchet teeth 59 in a circular array, the outer wall of the first interception net 1 is located at the axis of the ratchet teeth 59 and is rotatably connected to the square rod 510, the square rod 510 is slidably connected to the inside of the shaft 51, and a second spring 511 is fixedly connected between the ratchet disk 58 and the outer wall of the first interception net 1. The second interception net 41 is symmetrically slidably connected to the outer wall of the shaft 51, and the inner wall of the second interception net 41 is fixedly connected to a sliding ball slidably connected to the straight sliding groove 52 and the threaded sliding groove 53.

[0038] The distance adjustment component 5 also includes a second slide bar 512 that is slidably connected to the top of the first interception net 1, and the top of the second slide bar 512 is fixedly connected to a horizontal plate 513, and the bottom of the horizontal plate 513 is fixedly connected to a vertical tooth plate 514, and the vertical tooth plate 514 is slidably connected to the inside of the first interception net 1, and the vertical tooth plate 514 is engaged with the annular tooth groove 54 opened on the outer wall of the shaft rod 51, and the bottom of the horizontal plate 513 is fixedly connected to a hook-shaped plate 515, and the outer wall of the second interception net 41 is provided with a card slot 516, and the side of the card slot 516 away from the horizontal plate 513 is clamped in the inside of the card slot 516 of the second interception net 41, and a third spring 517 is fixedly connected between the second interception net 41 and the middle part of the upper surface of the first interception net 1.

[0039] The ratchet 59 and the ratchet disk 58 are unidirectionally engaged, and the shaft 51 rotates unidirectionally at the top of the first interception net 1. When the shaft 51 rotates unidirectionally, the symmetrical second interception nets 41 move away from each other. The bottom of the hook plate 515 is close to the side of the pull plate 55 and is set as an inclined surface. The bottom of the hook plate 515 is slidably connected to the inside of the first interception net 1, and the tooth block on the vertical tooth plate 514 is provided with a virtual position at the bottom of the vertical tooth plate 514.

[0040] When the third spring 517 is not compressed, the second intercepting net 41 is located on a side of the straight sliding groove 52 close to the threaded sliding groove 53 .

[0041] When the embodiment of the present invention is actually used, the staff will vertically drop the first interception net 1 into the canal. When the bottom of the drainage hole 3 fits the bottom of the canal and the first interception net 1 remains stable, the staff will step down on the horizontal plate 513. After being squeezed from above, the horizontal plate 513 will drive the second slide bar 512, the hook plate 515 and the vertical tooth plate 514 to slide downward inside the first interception net 1. When the hook plate 515 slides downward inside the first interception net 1, the second interception net 41 is no longer affected by the engagement of the hook plate 515 and the slot 516, so that the second interception net 41 is in a slidable state on the outer wall of the shaft rod 51. At this time, the third spring 517 in a compressed state elastically stretches and pushes the second interception net 41 to slide toward the side wall of the first interception net 1. The second interception net 41 slides downward. During the movement, the engagement of the horizontal tooth plate 42 and the gear shaft 43 will keep the second interception nets 41 on both sides in a relatively sliding state. When the second interception net 41 slides on the outer wall of the shaft rod 51, the sliding balls on the inner wall of the second interception net 41 will slide inside the straight slide groove 52. When the second interception net 41 slides to the side of the straight slide groove 52 close to the side wall of the first interception net 1, the staff continues to step down on the horizontal plate 513. At this time, the virtual position at the bottom of the vertical tooth plate 514 has dropped to the bottom. The horizontal plate 513 continues to move downward to engage the vertical tooth plate 514 with the annular tooth groove 54. The shaft rod 51 begins to rotate during the downward sliding of the vertical tooth plate 514. After the shaft rod 51 rotates, it will drive the second interception net 41 to continue to slide relatively far away through the threaded slide groove 53, thereby increasing the spacing between the symmetrical second interception nets 41.

[0042] During the process of the shaft 51 rotating to increase the spacing of the second interception net 41, the inclined surface of the ratchet disk 58 will fit and squeeze with the inclined surface of the ratchet teeth 59. During the rotation of the shaft 51, due to the limiting effect of the square rod 510 on the shaft 51, the shaft 51 will slide on the outer wall of the square rod 510 and make the ratchet disk 58 slide to the side away from the ratchet teeth 59. When the spacing of the second interception net 41 increases to match the width of the canal, the staff no longer rotates the shaft 51, and the ratchet disk 58 rotates in the opposite direction and fits its vertical surface with the vertical surface of the ratchet teeth 59. The ratchet disk 58 and the ratchet teeth 59 are engaged to limit the reverse rotation of the shaft 51, so that the width of the second interception net 41 will not be shortened due to squeezing, thereby improving the stability of the first interception net 1 when intercepting inside the canal.

[0043] When the horizontal plate 513 is stepped on, the hook-shaped plate 515 moves downward, so that the second interception net 41 is no longer limited and can slide relatively far away on the outer wall of the first interception net 1, which reduces the difficulty of the staff in adjusting the equipment, improves the adaptability of the first interception net 1 to canals of different widths, and extends the effective use range of the equipment. The second interception net 41 is driven to slide on the outside of the shaft 51 by the rotation of the shaft 51, which can effectively avoid the problem that the elastic force of the third spring 517 at the end of the elastic extension is insufficient, resulting in the side wall of the second interception net 41 being unable to fit tightly against the side wall of the canal, so that the equipment can maintain the stability of the first interception net 1 in the canal when facing canals of different widths.

[0044] See also Figures 8 to 10 The first interception net 1 is provided with a cleaning component 6 inside, which includes a circular shaft 61 symmetrically connected to the inside of the first interception net 1, and the outer wall of the circular shaft 61 is fixedly connected with fan blades 62 distributed in an annular array, and the single-side fan blades 62 cover the inside of the drainage hole 3. The top of the circular shaft 61 is fixedly connected to a round rod 63, and the outer wall of the round rod 63 is provided with a reciprocating thread groove 64. The outer wall of the round rod 63 is slidably connected with a slide plate 65, and the inner wall of the slide plate 65 is fixedly connected with a slider 66. The slider 66 is slidably connected to the inside of the reciprocating thread groove 64. The upper surface of the slide plate 65 is fixedly connected to the side close to the first interception net 1, and the upper surface of the slide plate 65 is fixedly connected to the side away from the first interception net 1. The second scraper 68 is fixedly connected to the side, and the first scraper 67 and the second scraper 68 are closed to each other to form a cavity. The inside of the cavity is slidably connected with a collecting bin 69. The top of the inner wall of the first interception net 1 is driven to be installed with a spiral blade 610.

[0045] The first scraper 67 and the second scraper 68 are both triangular in shape. The top of the first scraper 67 is close to the outer wall of the first interception net 1 and fits in with the outer wall of the first interception net 1 . The height of the first scraper 67 is three quarters of the second scraper 68 .

[0046] When the embodiment of the present invention is actually used, when the water in the canal impacts the first interception net 1, the water impacting the base 2 will be affected by the inclined surface of the base 2 and flow toward the first interception net 1 above the base 2, thereby ensuring the cleanliness of the base 2 during the interception process inside the canal. Part of the water will impact the inside of the drainage hole 3 after being intercepted, and pass through the inside of the first interception net 1 through the drainage hole 3. The water flowing through the inside of the first interception net 1 through the drainage hole 3 will impact the fan blade 62. The fan blade 62 will drive the circular shaft 61 to rotate under the action of the water impact, and the rotation of the circular shaft 61 will drive the circular rod 63 to rotate together. At this time, the slide plate 65 slidably connected to the outside of the circular rod 63 will slide upward during the rotation of the circular rod 63 because the slider 66 is slidably connected to the inside of the reciprocating thread groove 64. During the upward sliding of the slide plate 65, the first scraper 67 will scrape the debris attached to the first interception net 1. At this time Because the water flow first impacts the second scraper 68, a relatively stable space is generated between the first scraper 67 and the second scraper 68. The debris swept by the first scraper 67 will fall on the slide plate 65 and will be blocked by the second scraper 68 and the first scraper 67 and will not float around due to the impact of the water flow. When the slide plate 65 slides to the top on the outer wall of the round rod 63, the upper surface of the slide plate 65 will contact the spiral blade 610. The electrically driven rotating spiral blade 610 will push the debris deposited on the slide plate 65 to the cavities on both sides of the slide plate 65. When the debris is pushed to the collection bin 69 inside the cavity, the first interception net 1 is cleared once in the canal. The staff can clean the impurities collected on the collection bin 69 by extracting the collection bin 69. Then, as the round rod 63 continues to rotate, the slide plate 65 will slide downward on the outer wall of the round rod 63, thus repeating the cycle, so that the first scraper 67 can continuously clean and dredge the first interception net 1 during its use.

[0047] When the water flows through the drainage hole 3 and impacts the fan blade 62, the fan blade 62 drives the circular shaft 61 and the round rod 63 to rotate, and the slide plate 65 slides back and forth on the outer wall of the round rod 63, so that the first scraper 67 scrapes and dredges the first interception net 1 in a cycle, thereby reducing the problem that the water flow is difficult to pass through due to the blockage of a large amount of debris on the first interception net 1 when the first interception net 1 is performing interception work in the canal, and reducing the influence of the first interception net 1 on the flow rate of the canal after the installation. By arranging the first scraper 67 and the second scraper 68 in parallel on the slide plate 65, the water flow does not impact the first scraper 67 due to the shielding and guidance of the second scraper 68, so that a relatively stable space is formed between the first scraper 67 and the second scraper 68 in the water, so that the debris scraped off the first interception net 1 will not float around on the slide plate 65, so that the equipment can clean and collect the debris on the first interception net 1 in the water, and ensure that the first interception net 1 will not cause the problem of slow water flow rate due to blockage of debris.
