Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy projects, and in particular relates to a layered channel head gate with a lifting and blocking device. Background Art

[0002] As we all know, closing a sluice gate can prevent flooding, block tides, and store water to raise upstream water levels to meet upstream water intake or navigation needs. Opening a sluice gate can release floodwater, drain waterlogging, flush sediment, draw water, or regulate flow based on downstream water needs. Sluice gates are widely used in water conservancy projects, often constructed in rivers, canals, reservoirs, lakes, and coastal areas.

[0003] A search of publication number CN202227326U reveals a stratified headwater gate with stratified water intake and sediment interception. This stratified intake can accommodate varying water and sediment conditions, adapt to riverbed adjustments, guarantee the designed water diversion flow rate, and effectively maximize the benefits of irrigation projects. This gate can be widely used in the Yellow River irrigation area downstream and can also be applied to the headwaters of other sediment-rich rivers. It features a simple structure and flexible application. However, the aforementioned patent does not intercept floating debris on the water surface, allowing large amounts of floating debris to flow into the river, potentially clogging the downstream channel.

[0004] Publication number CN117071516A discloses a sewage interception device for water environment management that can mitigate the impact of water flow, thereby continuously and fully intercepting floating debris in the river. However, the aforementioned patent relies on the gravity of the counterweight to stretch and unfold the intercepting net, keeping it in a vertical position so that it can continuously intercept floating debris on the water surface. Furthermore, the sewage interception device in the aforementioned patent does not collect floating debris, and the suspended debris must be impacted by the water flow to the shore, where it can then be salvaged by staff. Utility Model Content

[0005] In response to the problems existing in the prior art, the utility model provides a layered head gate with a lifting pollution-blocking device, the purpose of which is to intercept and collect floating objects in front of the gate and reduce the flow of floating objects into the downstream river.

[0008] As a preferred technical solution, the interception component includes an interception net, which includes an interception part and a supporting part located below the interception part and extending toward the waterfront side, and a float floating with the water surface is fixedly connected to the supporting part and / or the water-receiving side of the interception part.

[0009] As a preferred technical solution, the floating body includes at least one floating block.

[0010] As a preferred technical solution, the floating body is provided with at least one hanging ring connected to the traction member of the lifting device.

[0025] The gate body includes gates 4, a hoisting and closing device 3, a lock chamber 2, and lock chamber sidewalls 1. The lock chamber sidewalls 1 are located on both sides of the gate body. A layered design is employed between the lock chamber sidewalls 1, with three levels of gates 4 arranged from bottom to top. Each level of gates 4 operates independently, opening individually or in combination depending on the flow rate and water level in front of the gate. The hoisting and closing device 3 and other related equipment are located in the lock chamber 2 at the top of the gate body, facilitating operator control of the gates 4.

[0026] The guide member includes a mounting rod 5; two mounting rods 5 are arranged side by side on the water-facing side of the gate body, the upper part of the mounting rod 5 is bent toward the gate body, and the upper end of the mounting rod 5 is welded and fixed to the steel embedded part embedded in the upper part of the gate body; the lower end of the mounting rod 5 extends to the bottom of the channel and is welded and fixed to the steel embedded part embedded in the bottom of the channel, thereby improving the overall stability of the mounting rod 5.

[0027] Preferably, the upper portion of the mounting rod 5 is bent with a rounded transition, which facilitates the production of the mounting rod 5 and facilitates the intercepting member to be smoothly raised to the top of the mounting rod 5 when it is raised, thereby improving the work efficiency of the staff.

[0028] Further preferably, the outer wall of the mounting rod 5 is coated with an anti-rust coating, such as anti-rust paint or other anti-rust substances, to prevent the mounting rod 5 from rusting when it is in a humid environment for a long time, thereby increasing its service life.

[0029] The interception component includes an interception net 8, which is fixedly connected to the water-facing side of the float and floats on the water surface by relying on the buoyancy of the float itself. Both sides of the float are slidably connected to the installation rod 5 through a guide part.

[0030] Preferably, the float includes at least one floating block 7 .

[0031] Further preferably, the floating block 7 is in the form of a rectangular parallelepiped, and both sides of the floating block 7 are connected to the guide portion by anchor bolts, so as to facilitate the later replacement of the floating block 7.

[0032] Further preferably, a fixed hanging ring 9 is welded to the backwater side of the floating block 7, and the lifting device pulls the intercepting net 8 by connecting the hanging ring 9.

[0033] Preferably, the guide portion is a collar 6 , and the collar 6 is slidably mounted on the mounting rod 5 .

[0034] Preferably, the interception net 8 includes an interception part and a supporting part; the supporting part and / or the interception part is fixedly connected to the water-facing side of the float, and can intercept floating objects on the water surface, effectively reduce the flow of floating objects into the downstream river channel, and prevent floating objects from blocking the downstream river channel; the supporting part is located at the lower part of the interception part and extends toward the water-facing side, and can collect suspended matter on the water surface. When the interception net 8 rises to the top of the installation pole 5, the supporting part can bring the collected floating objects to the top of the installation pole 5, and the staff can complete the cleaning work without going into the water.

[0035] Further preferably, the lateral length of the interception net 8 is the same as the width of the river channel, which increases the lateral contact area between the interception net 8 and the water surface and improves the interception and collection effect.

[0036] The lifting device includes a traction member, specifically a pulling rope 11; an electric winch 10 is installed on the top or water-facing side wall of the lock chamber 2, one end of the pulling rope 11 is wound on the electric winch, and the other end is detachably connected to the interception member. A device with a power generation function such as a solar power source or a traditional power source can be used as an electric drive. The staff can control the rotation of the electric winch 10 through a controller in the lock chamber 2 to complete the retraction and extension of the pulling rope 11. The pulling rope 11 is connected to the interception member, and starting the electric winch 10 can lift the interception net 8 to the top of the installation rod 5. The staff can clean the floating objects on the interception net 8 without going into the water; after the cleaning is completed, the interception net 8 is put back to the water surface along the installation rod 5, and the interception net 8 continues to intercept and collect suspended objects on the water surface, thereby improving the work efficiency of the staff.

[0037] Preferably, a hook 12 is provided at the lower end of the pulling rope 11, and the hook 12 and the hanging ring 9 are always in a connected state, thereby improving work efficiency.

[0038] Working principle:

[0039] Two mounting rods 5 are fixed to the front of the gate body. Their upper ends are welded to the upper steel components of the gate body, and their lower ends are welded to the steel components at the bottom of the gate. The outer surfaces of the mounting rods 5 are coated with an anti-rust coating to prevent rust and increase their service life. A collar 6 is slidably connected to each of the two mounting rods 5. A floating block 7 is installed between the two collars 6. Buoyancy forces these floating blocks to keep them afloat.

[0040] The interception net 8 includes an interception part and a supporting part; the interception part is fixedly connected to the water-facing side of the float 7, and can intercept floating objects on the water surface, effectively reducing the flow of floating objects into the downstream river channel, and preventing floating objects from blocking the downstream river channel; the supporting part is located at the lower part of the interception part and extends toward the water-facing side, and can collect suspended objects on the water surface. When the interception net 8 rises to the top of the installation rod 5, the supporting part can bring the collected floating objects to the top of the installation rod 5, and the staff can complete the cleaning work without going into the water.

[0041] The staff can control the rotation of the electric winch 10 through the controller in the lock room 2 to complete the retraction and extension of the pulling rope 11. The hook 12 on the pulling rope 11 is always connected to the hanging ring 9. Starting the electric winch 10 can lift the interception net 8 to the top of the installation rod 5. The interception net 8 is always connected to the installation rod, and the staff can clean the floating objects on the interception net 8 without going into the water; after completing the cleaning, the staff can start the electric winch 10 again to put the interception net 8 back to the water surface along the installation rod 5.
