Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a diversion channel constructed by alternating cofferdams in a highly permeable sand layer. Background Technology

[0002] The published patent with authorization announcement number CN211646262U discloses a diversion channel for alternating cofferdam construction in a highly permeable sand layer. The key technical points of the solution are: it includes a diversion channel, which includes side plates, a bottom plate, an inlet end, and an outlet end. The bottom plate is set in the horizontal direction, and the side plates are fixed to opposite sides of the bottom plate in the vertical direction. A filter screen is covered at the inlet end of the diversion channel. A fixing frame is set on the diversion channel, and a driving device for driving the filter screen to move up and down in the vertical direction is set on the fixing frame. A receiving claw is fixedly connected to the bottom of the filter screen in the horizontal direction. The receiving claw is located on the side of the filter screen away from the outlet end, which has the function of preventing debris in the river from clogging the diversion channel.

[0003] In the aforementioned patent, the diversion channel constructed with alternating cofferdams in a highly permeable sand layer has several drawbacks. During the cleaning of the filter screen, as the filter plate moves upward, debris on the receiving claws flows out through the gaps between the receiving claws and into the outlet of the diversion channel. As a result, a small amount of debris remains, leading to poor filtration. Furthermore, the drive device that moves the filter screen upward is manually controlled. The weight of the filter screen itself, combined with various debris, requires considerable hand strength to control its movement. In addition, the filter screen's positioning within the diversion channel is inadequate. When the water flow is strong, the bottom of the filter screen tends to tilt towards the outlet, creating gaps between the filter screen and the diversion channel, through which debris can flow in.

[0004] Therefore, this application proposes a diversion channel for alternating cofferdam construction in highly permeable sand layers. Utility Model Content

[0005] This application proposes a diversion channel for alternating cofferdam construction in highly permeable sand layers to solve the problems mentioned in the background art. By setting up a net, when the filter plate is raised to the water surface, there is no need to worry about debris continuing to flow into the diversion channel, thereby reducing the possibility of debris flowing into the diversion channel and reducing blockage. By setting up a drive mechanism, when the filter plate is raised to the water surface, the workers do not need to expend too much hand strength, reducing the labor intensity of the workers. By setting up a limiting plate, when the filter plate is used in the water, there is no need to worry about the bottom of the filter plate tilting due to water flow and water pressure, ensuring the stability of the filter plate during use, improving the filtration effect, and greatly enhancing the practicality of the device.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0020] In a preferred embodiment, both of the limiting grooves are formed inside the mounting bracket, and the two sides of the filter plate are slidably connected to the limiting grooves.

Detailed Implementation

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0031] Reference Figure 1-4 A diversion channel for alternating cofferdam construction in a highly permeable sand layer includes a diversion channel 1, an installation bracket 2, a filtration mechanism 3, a fixing frame 4, a fixing sleeve 5, a drive mechanism 6, and a limiting mechanism 7. The diversion channel 1 includes an inlet end 11 and an outlet end 12, which are respectively set at both ends of the diversion channel 1. The installation bracket 2 is installed on the diversion channel 1. The filtration mechanism 3 is set at the inlet end 11 of the diversion channel 1. The drive mechanism 6 is set on one side of the installation bracket 2. The limiting mechanism 7 is set on the installation bracket 2 and the inlet end 11 of the diversion channel 1.

[0032] Reference Figure 1-3 The filtration mechanism 3 includes a filter plate 31 and a net 32. The net 32 ​​is located on the side of the filter plate 31 away from the water outlet 12. By setting the net 32, when the filter plate 31 is raised to the water surface, there is no need to worry about debris continuing to flow into the guide channel 1, thereby reducing the possibility of debris flowing into the guide channel 1, reducing blockage, and thus improving the practicality of the device.

[0033] Reference Figure 1-4 The fixing frame 4 and the fixing sleeve 5 are both fixedly connected to the mounting bracket 2, and the fixing sleeve 5 is located above the fixing frame 4. By setting the fixing frame 4 and the fixing sleeve 5 on the mounting bracket 2, both are used to install the drive mechanism 6. The drive mechanism 6 drives the filter plate 31 to move up and down, thereby improving the practicality of the device.

[0034] Reference Figure 1-4 The drive mechanism 6 includes a winding shaft 61, a wire rope 62, a gear 63, a rack 64, and an electric cylinder 65. The winding shaft 61 is rotatably connected to the fixed frame 4, and the wire rope 62 is fixedly connected to the winding shaft 61. The other end of the wire rope 62 passes through the mounting bracket 2 and is fixedly connected to the top of the filter plate 31. By setting the drive mechanism 6, when the filter plate 31 is raised to the water surface, the worker does not need to expend too much hand strength, reducing the worker's labor intensity and thus improving the practicality of the device.

[0035] Reference Figure 1 ,2 4. A gear 63 is fixedly connected to one end of the winding shaft 61 and inside the fixed frame 4. A rack 64 is slidably connected inside the fixed frame 4, and the gear 63 and the rack 64 are meshed together. The meshing of the rack 64 and the gear 63 will cause the gear 63 to rotate, and the gear 63 will drive the winding shaft 61 connected to it to rotate synchronously, thereby improving the practicality of the device.

[0036] Reference Figure 1 , 2 4. An electric cylinder 65 is fixedly connected inside the fixed sleeve 5, and the telescopic end of the electric cylinder 65 is fixedly connected to the top of the rack 64. By driving the electric cylinder 65, the electric cylinder 65 drives the rack 64 to move down, and the rack 64 meshes with the gear 63, which will cause the gear 63 to rotate, thereby improving the practicality of the device.

[0037] Reference Figure 1-3 The limiting mechanism 7 includes a limiting groove 71 and a limiting plate 72. Each limiting plate 72 is installed inside the guide channel 1, and the two sides of the filter plate 31 abut against the two limiting plates 72. By setting the limiting plate 72, when the filter plate 31 is used in water, there is no need to worry about the bottom of the filter plate 31 tilting due to water flow and water pressure, ensuring the stability of the filter plate 31 during use, improving the filtration effect, and thus enhancing the practicality of the device.

[0038] Reference Figure 1-3 Both limiting grooves 71 are opened inside the mounting bracket 2, and the two sides of the filter plate 31 are slidably connected to the limiting grooves 71. By setting the limiting plate 72, when the filter plate 31 is used in water, there is no need to worry about the bottom of the filter plate 31 tilting due to water flow and water pressure, ensuring the stability of the filter plate 31 during use, improving the filtration effect, and thus enhancing the practicality of the device.

[0039] Working principle: When debris flows and approaches the outlet 12 of the guide channel 1, the filter plate 31 blocks the debris from entering the guide channel 1, preventing it from clogging the channel. Simultaneously, debris accumulates on the filter plate 31. When too much debris accumulates on the filter plate 31, the electric cylinder 65 is activated. The electric cylinder 65 drives the rack 64 downwards. The rack 64 meshes with the gear 63, causing the gear 63 to rotate. The gear 63 then drives the connected winding shaft 61 to rotate synchronously. When the winding shaft 61 rotates, it winds the wire rope 62, causing the wire rope 62 to shorten gradually. This causes the filter plate 31 to rise above the water surface. During the upward movement of the filter plate 31, the net 32 ​​located on one side of the filter plate also rises. During the rising process, debris falling from the filter plate 31 and debris on the net 32 ​​itself will be lifted to the outside of the water surface. At this time, the debris can be cleaned out of the net 32 ​​by the construction personnel, thus achieving the cleaning of debris. By setting the net 32, when the filter plate 31 is lifted to the water surface, there is no need to worry about debris continuing to flow into the guide channel 1, thereby reducing the possibility of debris flowing into the guide channel 1 and reducing blockage. By setting the drive mechanism 6, when the filter plate 31 is lifted to the water surface, the workers do not need to expend too much hand strength, reducing the labor intensity of the workers. By setting the limiting plate 72, when the filter plate 31 is used in the water, there is no need to worry about the bottom of the filter plate 31 tilting due to water flow and water pressure, ensuring the stability of the filter plate 31 during use and improving the filtration effect.
