Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and in particular to a silt suction component for open channels. Background Technology

[0002] In water conservancy projects, open channels often become silted up due to natural sediment deposition, rain erosion, and reduced water flow velocity. This leads to decreased water flow smoothness, weakened water conveyance capacity, and even flooding or ecological problems. The siltation process is mainly caused by the settling of sediment carried by the water flow when the flow velocity decreases or the local structure of the channel changes. To address this problem, a silt suction component for open channels has been developed. This component is suitable for various scenarios such as farmland irrigation canals, urban drainage systems, river dredging, and reservoir maintenance, providing important technical support for the long-term operation and ecological protection of open channels.

[0003] A typical open channel silt suction assembly consists of a suction inlet, a mixing device, a suction pipe, and a silt collection device. The suction inlet mixes the silt with water and then pumps it into the pipe. The mixing device loosens the silt, improving suction efficiency and preventing blockages. The suction pipe transports the silt to the collection device. The entire assembly is compact and functionally integrated, not only improving the efficiency of open channel dredging but also reducing secondary environmental impacts, making it widely applicable to water conservancy projects and ecological restoration scenarios.

[0004] While existing sediment extraction equipment has achieved some success in clearing open channel siltation, several shortcomings remain. For example, the equipment is poorly adaptable to different locations and depths within open channels, making it difficult to efficiently cover complex terrain. Furthermore, traditional screens are mostly fixed designs, prone to clogging by sediment, which reduces separation efficiency, and lack optimization features for gravity separation. In addition, the treatment methods for separated sediment are relatively limited, failing to fully realize resource utilization and restricting further improvement in economic and environmental benefits. These issues provide room for technological improvements to meet practical needs in a more flexible, efficient, and environmentally friendly manner.

[0005] To address the above problems, a silt suction component for open channels is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a silt suction component for open channels, which aims to solve the problems of low silt separation efficiency, inconvenient processing, and insufficient resource utilization of existing silt suction components during operation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a silt suction component for open channels, comprising two bases and a guide groove, wherein four casters are installed side by side at the bottom of the bases, four hydraulic support columns are symmetrically arranged between the two bases and the guide groove, a moving component is provided inside the guide groove, and a cleaning mechanism is provided directly below it.

[0008] The cleaning mechanism includes a cleaning box, the interior of which is divided into three parts: a mechanical chamber, a filtering chamber, and a squeezing chamber. The mechanical chamber and the filtering chamber are separated by a partition. A suction assembly is installed inside the mechanical chamber, and a filtering and squeezing assembly is installed inside the filtering chamber and the squeezing chamber.

[0009] As a further description of the above technical solution:

[0010] The suction assembly includes a second motor and a water pump. The output end of the second motor is fixedly connected to a connecting rod, and a stirring blade is installed at the bottom of the connecting rod. The input end of the water pump is connected to an absorption hood through a pipe.

[0011] As a further description of the above technical solution:

[0012] The absorption shroud is located diagonally above the stirring blades, and the second motor is located on the side of the water pump.

[0016] The filter plate is installed at an angle at the bottom of the filtration chamber, and the inside of the extrusion chamber is equipped with an automatic door.

[0017] As a further description of the above technical solution:

[0018] The output end of the water pump is connected to the interior of the filter chamber through a pipe, and the water pump is fixed inside the partition.

[0019] As a further description of the above technical solution:

[0022] The lead screw is rotatably connected inside the slider, and the output end of the motor is fixedly connected inside the lead screw.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the equipment, through the cooperation of the base, hydraulic support column cylinder, and moving components, enables the cleaning mechanism to be flexibly adjusted to cover different positions and depths of open channels, adapting to complex terrain. The combination of stirring blades and water pump can quickly loosen and extract accumulated silt and sand, ensuring the efficient operation of the equipment.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 - Figure 3This utility model provides an embodiment of a silt suction assembly for open channels, comprising two bases 1 and a guide groove 3. Four casters 2 are mounted side-by-side on the bottom of the bases 1 for easy movement of the equipment. Four hydraulic support columns 4 are symmetrically arranged between the two bases 1 and the guide groove 3 for adjusting the height and stability of the equipment. A moving assembly 5 is installed inside the guide groove 3, comprising a slide rail 501 and a motor 505. A groove 502 is formed inside the slide rail 501, and a slider 504 is slidably connected inside the groove 502. A lead screw 503 is rotatably connected inside the slide rail 501. The lead screw 503 is driven by the motor 505 to rotate, thereby driving the slider 504 to move along the groove 502, enabling the equipment to be precisely positioned at different locations in the open channel along the guide groove 3. A cleaning mechanism 6 is located directly below the guide groove 3. The cleaning mechanism 6 includes a cleaning box 601, which is internally divided into a mechanical chamber 602, a filtering chamber 603, and a squeezing chamber 604. The mechanical chamber 602 and the filtration chamber 603 are separated by a partition 610. The mechanical chamber 602 contains a suction assembly, which includes a second motor 605 and a water pump 608. A connecting rod 606 is fixedly connected to the output end of the second motor 605, and a stirring blade 607 is installed at the bottom of the connecting rod 606. The stirring blade 607 is used to loosen the silt at the bottom of the open channel. The input end of the water pump 608 is connected to an absorption hood 609 via a pipe. The absorption hood 609 is located diagonally above the stirring blade 607, enabling efficient suction of the silt-water mixture. The output end of the water pump 608 is connected to the interior of the filtration chamber 603 via a pipe. A filter plate 611, inclined at the bottom of the filtration chamber 603, separates the silt and water using gravity. The filtered silt slides into the squeezing chamber 604, achieving initial separation.

[0034] Reference Figure 3 - Figure 4 A cylinder 612 is installed at the top of the extrusion chamber 604. An extrusion block 614 is fixedly connected to the output end of the cylinder 612. The extrusion block 614 is slidably connected to a limiting guide rail 615 inside the extrusion chamber 604 via grooves on both sides, ensuring the stability and accuracy of its movement. After the sediment, initially separated in the filtration chamber 603, slides into the extrusion chamber 604, the extrusion block 614, driven by the cylinder 612, performs high-pressure extrusion on the sediment, pressing it into a compacted mud cake. An automatic door 613 is also installed inside the extrusion chamber 604 to discharge the pressed mud cake. In this way, the separated sediment is utilized as a resource; the mud cake can be used for building materials such as bricks, roadbed materials, or agricultural applications such as soil conditioners. Simultaneously, the water separated during the extrusion process can be purified and recycled back to the suction equipment, further improving the environmental friendliness and water resource utilization rate of the equipment. The design of the entire system enables efficient cleaning, separation, and resource utilization of silted sediment in open channels, providing a highly efficient, energy-saving, and environmentally friendly solution for water conservancy projects.

[0035] Working Principle: The open channel silt suction assembly is adjusted via a base 1, hydraulic support column 4, and cylinder 612. It utilizes a moving assembly 5 (slide rail 501, slider 504, lead screw 503, and motor 505) to achieve precise cleaning of different locations and depths within the open channel. The cleaning mechanism 6 consists of a cleaning box 601, which is divided into a mechanical chamber 602, a filtration chamber 603, and a squeezing chamber 604. In the mechanical chamber 602, the stirring blades 607, driven by motor 605, loosen the silt. A water pump 608 draws in the mixture of silt and water through an absorption hood 609 and transports it to the filtration chamber 603. The silt undergoes initial separation on the inclined filter plate 611 under gravity. The silt slides into the squeezing chamber 604, while the water flows back into the open channel through the filter plate 611. The compression chamber 604, driven by the cylinder 612, compresses the sediment under high pressure through the compression block 614, forming a mud cake which is then discharged through the automatic door 613 for easy storage and resource utilization. Water, after filtration, can be returned to the open channel. The entire system achieves efficient cleaning, separation, and treatment of sediment.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
