Description

Technical Field

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

[0002] River siltation is an important water conservancy engineering activity that aims to remove the silt accumulated at the bottom of the river to maintain or restore the normal functions of the river, including flood control, drainage, irrigation, water supply, navigation and ecological health. Over time, natural processes and human activities will lead to river siltation, which not only affects the hydrological cycle, but may also cause flood disasters, reduce the navigation capacity of the waterway, and affect the sustainable use of water resources. Therefore, river siltation is of great significance to maintaining the health of the water system, ensuring water security and promoting social and economic development.

[0003] Traditional river dredging usually uses plate scraper equipment and negative pressure pumps, that is, several groups of scrapers follow the circulation belt to circulate in the river, scraping the silt in the river away from the water, and then sucked away by the negative pressure pump. The two are used in combination, or the negative pressure pump can also be directly extended into the water to extract by negative pressure. However, the silt is prone to contain hard impurities such as stones, and the hard impurities are easily stuck in the negative pressure pump, resulting in malfunction. Plate scraper equipment alone cannot handle the hard impurities, which in turn affects the efficiency and reliability of dredging. Utility Model Content

[0020] As a further technical solution, the frame is used to be arranged on the inner wall of the river channel, and the frame is a telescopic frame.

[0021] The working principle and beneficial effects of the utility model are:

[0022] In the utility model, the traditional use of plate scraping equipment and negative pressure pumps or the direct use of negative pressure pumps may cause hard impurities in the sludge to be stuck in the negative pressure pump, thereby affecting the efficiency and reliability of dredging. In order to avoid the above situation, a river dredging device is designed; it mainly relies on the plate scraping principle, through the coordinated use of scraping action and filter holes, to achieve that during the scraping process, the hard impurities in the sludge will not be adsorbed by the negative pressure pump, but will be directly sieved by the filter holes and remain underwater, and only the sludge needs to be cleaned away.

[0023] Specifically, the steel structure frame is first installed on the inner wall of the river channel to provide stable support for components such as the circulation belt and the silt removal plate to prevent the water flow in the river channel from breaking through the silt removal device; the combination of the efficient silt removal circulation belt and the silt removal plate can effectively scrape and carry silt in the underwater area, that is, utilize the plate scraping principle to transport the silt to the above-water area, realizing a continuous silt removal process and improving silt removal efficiency.

[0024] The inclined setting of the supporting frame used to support the circulation belt and the dredging plate enables the device to adapt to waters of different depths. Whether it is shallow water or deep water, dredging operations can be carried out effectively, which improves the applicability of the equipment. At the same time, the supporting frame is connected to the frame to facilitate early production and installation, avoiding the need to adjust the position of the entire underwater frame when the position needs to be adjusted, thereby greatly improving the practicality of the dredging device.

[0025] Further, a plurality of filter holes are distributed between two adjacent silt cleaning plates, which greatly improves the utilization rate of the filter holes. When the silt cleaning plates carry the silt and hard impurities away from the water, the hard impurities can be smoothly screened by each filter hole and separated from the silt due to the swaying back and forth under water. Even if some of them are not separated, they will be screened out by the filter holes in the process of the above-water area. Moreover, since the silt has good integrity when scraped off, it will not be easily discharged from the filter holes. The device reduces the cost of silt treatment through efficient silt removal and hard impurity separation. At the same time, it reciprocates between the above-water area and the underwater area to realize the self-cleaning function of the silt cleaning plate, reduce maintenance costs, and improve the economic benefits of silt cleaning operations as a whole.

[0026] At the same time, the frame can adopt a telescopic structure to more widely adapt to different working conditions. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0035] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0036] Reference Figure 1~Figure 3 , which is the first embodiment of the utility model, proposes a river dredging device, including: a frame 1: a supporting frame 2, the supporting frame 2 is tiltedly arranged on the frame 1, and the supporting frame 2 is divided into an above-water area 3 and an underwater area 4 from top to bottom; a circulating belt 5, the circulating belt 5 is circulated on the supporting frame 2; a plurality of dredging plates 6, and the plurality of dredging plates 6 are all arranged on the circulating belt 5. After the circulating belt 5 circulates, the dredging plates 6 alternately pass through the above-water area 3 and the underwater area 4; wherein, the circulating belt 5 has a plurality of filter holes 501, the filter holes 501 are located between two adjacent dredging plates 6, and the filter holes 501 are used to pass hard impurities.

[0037] In this embodiment, Figure 1 , 2As shown, the traditional use of plate scraping equipment and negative pressure pumps or direct use of negative pressure pumps may cause hard impurities in the sludge to be stuck in the negative pressure pump, thereby affecting the efficiency and reliability of dredging. In order to avoid the above situation, a river dredging device is designed; it mainly relies on the plate scraping principle, through the scraping action and the use of filter holes 501, to achieve that during the scraping process, the hard impurities in the sludge will not be adsorbed by the negative pressure pump, but will be directly sieved by the filter holes 501 and remain underwater, and only the sludge needs to be cleaned away.

[0038] Specifically, the steel structure frame 1 is first installed on the inner wall of the river channel to provide stable support for components such as the circulation belt 5 and the silt removal plate 6 to prevent the water flow in the river channel from breaking through the silt removal device; the combination of the efficient silt removal circulation belt 5 and the silt removal plate 6 can effectively scrape and carry silt in the underwater area 4, that is, utilize the plate scraping principle to transport the silt to the above-water area 3, thereby realizing a continuous silt removal process and improving the silt removal efficiency.

[0039] The support frame 2 for supporting the circulation belt and the dredging plate 6 is arranged inclined, so that the device can adapt to waters of different depths. Whether it is shallow water or deep water, dredging operations can be effectively carried out, thereby improving the applicability of the equipment. At the same time, the support frame 2 is connected to the frame 1 to facilitate early production and installation, avoiding the need to adjust the position of the entire underwater frame 1 when the position needs to be adjusted, thereby greatly improving the practicality of the dredging device.

[0040] Further, a plurality of filter holes 501 are distributed between two adjacent silt cleaning plates 6, which greatly improves the utilization rate of the filter holes 501. When the silt cleaning plate 6 takes the silt and hard impurities away from the water, the hard impurities can be smoothly screened by each filter hole 501 and separated from the silt due to the swaying back and forth in the water. Even if some of them are not separated, they will be screened out by the filter holes 501 during the process in the above-water area 3. Moreover, since the silt has good integrity when scraped off, it will not be easily discharged from the filter holes 501. The device reduces the cost of silt treatment through efficient silt removal and hard impurity separation. At the same time, it reciprocates between the above-water area 3 and the underwater area 4 to realize the self-cleaning function of the silt cleaning plate 6, reduce maintenance costs, and improve the economic benefits of silt cleaning operations as a whole.

[0041] At the same time, the frame 1 can adopt a telescopic structure to more widely adapt to different working conditions.

[0042] Furthermore, a plurality of silt-clearing plates 6 are arranged at equal intervals on the circulating belt 5 , and the silt-clearing plates 6 are detachably arranged on the circulating belt 5 by fasteners.

[0043] In this embodiment, Figure 2As shown, the dredging plates 6 made of steel structure materials such as rectangular or square cross-sections are evenly arranged on the circulation belt 5, and combined with the inclined setting of the supporting frame 2, the device can flexibly adapt to the river environment with different water depths and silt thicknesses, and evenly scrape the silt in the river channel. It can operate efficiently in both shallow water areas and deep water areas, broadening the application range of the equipment and significantly improving the dredging efficiency. The evenly spaced distribution of the dredging plates 6 and the coordinated work of the circulation belt 5 ensure the continuous scraping and uniform transportation of silt, avoid silt accumulation or omission, improve the continuity and efficiency of dredging operations, and accelerate the dredging progress.

[0044] Furthermore, in order to quickly replace the corroded or damaged silt cleaning plate 6 and simplify the maintenance process, the silt cleaning plate 6 is detachably set on the circulating belt 5 by fasteners such as bolts. The whole is made of anti-corrosion material to improve the service life. The connection tightness of fasteners such as bolts can also ensure the normal use of the silt cleaning plate 6 and protect key components from additional stress.

[0045] Furthermore, it also includes: a connecting block 8, and the supporting bracket 2 is obliquely arranged on the frame 1 through the connecting block 8.

[0046] In this embodiment, Figure 2 , 3 As shown, the tilt setting is usually achieved by fasteners such as bolts. However, since the circulating belt 5 and the support bracket 2 are relatively heavy as a whole and are suspended underwater, fasteners and the like may cause uneven stress and displacement of the support bracket 2. Therefore, in order to avoid the above situation and ensure the quick disassembly efficiency of the support bracket 2, a whole connecting block 8 is used to achieve this. Although fasteners are still used, the support bracket 2 is not fixed at a certain angle by fasteners alone. Instead, holes are opened at different positions of the connecting block 8, and the holes at different positions are respectively connected to the support bracket 2 and the frame 1 through fasteners. The support bracket 2 and the frame 1 are connected by the connecting block 8 to ensure their tilt setting.

[0047] Furthermore, the connecting block 8 has a positioning hole 801 at one end and an arc-shaped positioning groove 802 at the other end. The positioning hole 801 and the arc-shaped positioning groove 802 are respectively connected to the support bracket 2 and the frame 1 through fasteners. The support bracket 2 is arranged on the frame 1 with an adjustable angle.

[0048] In this embodiment, Figure 2 , 3As shown, the specific connecting block 8 adopts a trapezoidal structure, which can better ensure the stability of the structure. A positioning hole 801 and an arc-shaped positioning groove 802 for connecting the support bracket 2 and the frame 1 are respectively opened at both ends. The fastener is locked with the support member through the positioning hole 801, and the remaining fasteners are locked with the frame 1 by passing through the arc-shaped positioning groove 802 after determining the inclination angle of the support bracket 2 and the frame 1, thereby ensuring the stable inclination of the support bracket 2, reducing the vibration and displacement of the equipment during operation, protecting key components from additional stress, and extending the overall service life of the equipment.

[0049] The use of the arc-shaped positioning groove 802 can just adapt to the various tilt angles of the support bracket 2 and the frame 1, so that it can have a contact surface with the frame 1 no matter what angle it is swung to, making it easy for the fastener to penetrate and realize the stable connection between the connecting block 8 and the frame 1.

[0050] Furthermore, the connecting block 8 also has a connecting hole 803 , and the connecting hole 803 is located between the positioning hole 801 and the arc-shaped positioning groove 802 . There are a plurality of supporting brackets 2 , and the plurality of supporting brackets 2 are connected in sequence through the connecting hole 803 .

[0051] In this embodiment, Figure 1 , 3 As shown, in order to improve the treatment quality and treatment efficiency of the dredging device, comprehensively cover the entire cross-section of the river channel, and avoid the need for additional customized production of supporting frames 2, circulation belts 5 and dredging plates 6 of corresponding specifications each time, it is set up that several groups of minimum unit dredging devices can be connected side by side along the width of the river channel in sequence to adapt to different working occasions.

[0052] Specifically, with the help of the connecting block 8 again, several groups of dredging devices are connected side by side by the connecting block 8, and then a connecting hole 803 is opened between the positioning hole 801 and the arc-shaped positioning groove 802 of the connecting block 8, which can also avoid interference with other components. At the same time, the connecting block 9 is interference-fitted in the connecting hole 803, so that the connecting blocks 8 on two groups of different supporting frames 2 can be connected to complete the assembly of the dredging device adapted to the river channel.

[0053] Furthermore, there are several connecting blocks 8 , each of which is provided on both sides of the supporting bracket 2 , and further includes: a clamping block 9 , which is detachably provided in the connecting hole 803 , and the clamping block 9 is connected to two adjacent supporting brackets 2 .

[0054] Furthermore, the circulating direction of the circulating belt 5 is arranged along the length direction of the supporting frame 2, and a plurality of supporting frames 2 are arranged along the width direction thereof.

[0055] Furthermore, the frame 1 is used to be arranged on the inner wall of the river channel, and the frame 1 is a telescopic frame 1.

[0056] In this embodiment, Figure 1 ,3 As shown, a trapezoidal clamping block 9 made of anti-corrosion material can be specifically used, and its two ends are respectively interference fit with the connecting holes 803 of the connecting blocks 8 on different groups of supporting brackets 2, that is, the wedge block principle, to complete the assembly. At the same time, connecting blocks 8 are provided on both sides of the supporting bracket 2, which, on the one hand, play the role of stabilizing the supporting bracket 2, and on the other hand, facilitate the connection of several groups to adapt to the river channel.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
