Description

A garbage interception and treatment device for water conservancy projects

Technical Field

The invention belongs to the technical field of water conservancy projects, and in particular relates to a garbage interception and treatment device for water conservancy projects.

Background Art

Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is a valuable resource that is indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flows, prevent floods and waterlogging disasters, and regulate and distribute water to meet people's needs for water resources in life and production. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their goals. Flood control dams are one of the water conservancy projects set up to intercept floods to prevent soil erosion and ecological damage downstream.

Water conservancy projects are all equipped with waterproof gates to achieve the purpose of flood control and irrigation. Since the waterproof gate is the only way for water to flow into the downstream, a large amount of garbage often gathers here. After the garbage accumulates, it will block the valve, resulting in poor drainage of the valve and pollution of the downstream. At present, the garbage at the gate is generally collected through a filter net, and then the collected garbage is salvaged manually, or a surface garbage interception and cleaning device is set up upstream of the sluice to avoid blockage and damage to the sluice equipment. The existing sluice garbage interception and cleaning equipment also manually cleans the intercepted garbage during use, which requires a lot of manpower.

A Chinese patent with authorization announcement number CN113774870B discloses a garbage interception device for a water gate in a water conservancy project. Through a water wheel driving mechanism, the impact of the water flow can provide power for the rotary wheel to salvage when the gate releases water, which not only reduces the cost of garbage salvage, but also can automatically adjust the rotation speed according to the size of the water flow to ensure the flexibility of garbage salvage; the arc plate on the second rotating shaft can quickly cut into the water to reduce the water resistance, and can convert the energy of the water into driving force to the maximum extent; and through the belt drive, the first rotating shaft and the second rotating shaft can have the same direction of rotation, and the garbage in the water can be pushed onto the transmission belt to avoid energy waste.

In view of the above problems, the existing patents provide solutions, but the salvage depth is fixed, which means that when installing interception mechanisms on different gates, interception mechanisms of different specifications need to be produced, which leads to poor adaptability of the interception mechanisms and increases production difficulty and cost.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Referring to FIG. 1 and FIG. 2 , the present invention provides a garbage interception and treatment device for water conservancy projects, comprising:

The garbage interception mechanism comprises a concrete body and a first filter plate 1, wherein the concrete body is provided with an opening, and the first filter plate 1 is installed on the opening;

The garbage transport mechanism comprises a support assembly, a base plate 2 and a second filter plate 3. The concrete body is provided with support assemblies on both sides of the left and right sides of the first filter plate 1. The support assembly comprises a positioning rod 4 and a fixing rod 5 connected to both ends of the positioning rod 4. The fixing rod 5 is connected to the concrete body. The two ends of the base plate 2 are movably sleeved on the fixing rods 5 on both sides. A buoyancy assembly 6 is provided below the base plate 2. An axial drive assembly that moves axially along the base plate 2 is provided above the base plate 2. The second filter plate 3 is installed on the moving module of the axial drive assembly to transport the garbage in front of the first filter plate 1.

The garbage centralized salvaging mechanism includes two centralized storage boxes 7 symmetrically arranged on both sides of the concrete body. The centralized storage box 7 is provided with a channel along the water flow direction. A third filter plate 27 is installed behind the channel. A salvage port 8 connected to the channel is opened on the top surface of the centralized storage box 7. A garbage salvaging component that can be extended into the channel for garbage cleaning is installed at the salvage port 8.

This garbage interception and processing device is installed upstream of the waterproof gate of the water conservancy project. It is used to intercept and collect garbage in advance to avoid blocking and damage to the waterproof gate. Its specific working principle is as follows:

When water flows through the garbage interception and treatment device, the garbage in the water is intercepted by the first filter plate 1, so that the garbage is accumulated in front of the first filter plate 1. The axial drive component moves the second filter plate 3 along the axial direction of the base plate 2 through the moving module, so as to transport the garbage floating on the water surface to the storage and collection box 7 on the side. Since a buoyancy component 6 is provided under the base plate 2, the buoyancy component 6 can adopt buoyancy plates, inflatable air bags and inflatable hollow structure tanks in conventional technical means, which can ensure that the base plate 2 can adjust its height as the water level changes, thereby ensuring the smoothness of the garbage transportation process; when the garbage enters the channel of the storage and collection box 7, the third filter plate 27 intercepts the garbage. After a part of the garbage is concentrated, the garbage salvaging component can be extended from the salvage port 8 into the channel of the storage and collection box 7, and salvage and cleaning operations can be performed regularly. Through this design, the garbage interception and treatment device can effectively intercept and clean up garbage in the water. Compared with the traditional manual cleaning method, it significantly reduces labor intensity and improves work efficiency. The setting of the buoyancy component 6 enables the garbage transport mechanism to automatically adjust its height according to water level changes, ensuring a smooth garbage transport process. It greatly enhances the adaptability of the garbage interception and treatment device under different water level conditions, effectively solves the operational difficulties that may be caused by water level changes, and ensures continuous and stable garbage cleaning capabilities.

In a specific embodiment, referring to FIG. 2 , the axial drive assembly includes an electric slide rail 9 , the movable module is a slider 10 , the slider 10 is slidably mounted on the electric slide rail 9 , and the second filter plate 3 is mounted on the slider 10 .

The electric slide rail 9 and the slider 10 are used to control the movement of the second filter plate 3. The structure is simple, the operation is stable, the maintenance is convenient, and the precise linear motion control is provided. The device can operate stably in the harsh environment of the water conservancy project for a long time, and ensures the continuous and effective operation of the garbage interception and treatment device. The system can be remotely controlled manually, and a timed start can be set to realize automatic operation. Compared with manual cleaning, the labor intensity is greatly reduced and the work efficiency is improved.

In a specific embodiment, referring to Figures 1 and 4, the garbage salvage assembly includes a salvage grid 11, a connecting bracket 12 and a hoist. The salvage grid 11 and the connecting bracket 12 are both arranged in the channel. The salvage grid 11 is installed on the connecting bracket 12. A pull rope 13 is connected to the connecting bracket 12. The pull rope 13 is connected to the output end of the hoist. The hoist is installed on the top surface of the storage concentration box 7.

The garbage salvage assembly consists of a salvage grid 11, a connecting bracket 12 and a hoist. The operator only needs to control the hoist and lift the salvage grid 11 from the storage box 7 to the salvage port 8 through the pull rope 13. During the lifting process, the salvage grid 11 can effectively collect the garbage in the channel, which greatly reduces the labor intensity of manual garbage cleaning, reduces labor costs and safety risks of cleaning personnel, and effectively improves the work efficiency and safety during the garbage salvage process.

In a specific embodiment, referring to FIG. 3 , the hoist includes a lifting frame 14, a drum 15 and a servo motor 16. The lifting frame 14 is installed above the salvage port 8. A pulley 17 is connected to the lifting frame 14. The drum 15 and the servo motor 16 are both installed on the top surface of the storage concentration box 7. The pull rope 13 passes through the pulley 17 and is wound around the drum 15. The servo motor 16 is connected to the drum 15 through a gear transmission box.

The hoist drives the drum 15 through the servo motor 16 and the gear transmission box, and the pulley 17 provides steering, thereby lifting the salvage grid 11. It not only realizes an efficient, accurate and automated garbage lifting process, but also has the characteristics of compact structure, stable operation, easy maintenance and high safety, which significantly improves the overall performance and operation effect of the garbage interception and processing device.

In a specific embodiment, referring to Figures 1, 4 and 5, the storage concentration box 7 is provided with an unloading plate 18 on one side of the salvage port 8, and the salvage grid 11 can be rotatably set on the connecting bracket 12. Four supporting legs 19 overlapped on the connecting bracket 12 are vertically and parallelly arranged on one side of the salvage grid 11, and four legs 20 are horizontally and parallelly arranged on the other side. The legs 20 are located below the unloading plate 18, and the salvage grid 11 can be rotated when the legs 20 are against the unloading plate 18, so that the salvage grid 11 is tilted toward the unloading plate 18.

Through this design, the salvage grid 11 can be rotated. During the lifting process, the support legs 19 are overlapped on the connecting bracket 12 at the beginning, and the support legs 19 provide support force for the salvage grid 11, so that the salvage grid 11 remains horizontal. Later, when the legs 20 are against the unloading plate 18, the bottom surface of the unloading plate 18 presses down on the legs 20, which can make the salvage grid 11 tilt toward the unloading plate 18, so that the salvaged garbage slides along the inclined surface and automatically slides the salvaged garbage onto the unloading plate 18, realizing automatic unloading, reducing manual operation, speeding up the garbage cleaning process, and improving work comfort and efficiency. In addition, the rotatable design of the salvage grid 11 and the coordinated setting of the legs 20 and the unloading plate 18 have a simple structure, and can realize tilted unloading without complex mechanical devices, reducing the complexity and failure rate of the system, and facilitating use.

In a specific embodiment, referring to Figures 4 and 5, the connecting bracket 12 includes a balancing frame 1201 and a connecting rod 1202, the supporting leg 19 is overlapped on the balancing frame 1201, and connecting legs 1203 are provided on both sides of the balancing frame 1201. The connecting legs 1203 are arranged close to the legs 20, and the connecting legs 1203 are fixedly connected with fixed blocks 1204. The two sides of the salvage grid 11 are rotatably connected to the fixed blocks 1204 on both sides through the rotating shaft 21, and the two ends of the connecting rod 1202 are respectively connected to the connecting legs 1203 on both sides, and the pull rope 13 is connected to the middle part of the connecting rod 1202.

Through the design of the balance frame 1201 and the connecting leg 1203, when the pull rope 13 is lifted, the support leg 19 is overlapped on the balance frame 1201, so that the salvage grid 11 remains horizontal. In the process of the leg 20 abutting against the unloading plate 18, the unloading plate 18 presses down the leg 20, and the salvage grid 11 automatically rotates through the rotating shaft 21, thereby realizing the operation of tilting for automatic unloading. In addition, the connecting leg 1203 is arranged close to the leg 20, so that a larger rotation angle can be achieved at a smaller downward pressing height, and the spatial layout of the salvage grid 11 and the connecting bracket 12 is optimized. This design ensures the applicability of the equipment in a compact installation environment while maintaining the stability and space efficiency of the overall structure.

In a specific embodiment, referring to Figure 1, the concrete body includes a support frame 22 and an inclined plate 23, the opening is set on the support frame 22, the number of the inclined plates 23 is two, and they are symmetrically installed on both sides of the support frame 22, the other end of the inclined plate 23 is connected to the storage concentration box 7, and is inclined from the first filter plate 1 toward the third filter plate 27, and the fixing rod 5 is connected to the inclined plate 23.

The support frame 22 provides a stable installation condition for the first filter plate 1, and the inclined plates 23 are arranged on both sides of the support frame 22 and are inclined from the first filter plate 1 toward the third filter plate 27, which can effectively guide the garbage pushed by the second filter plate 3 to smoothly enter the storage and collection box 7. This design is different from the traditional flat plate structure, avoids the accumulation of garbage on the flat plate, and reduces the risk of water flow again flushing the garbage, which significantly improves the cleaning efficiency and capacity of the garbage interception and processing device.

In a specific embodiment, referring to FIG. 1 , the front of the storage concentration box 7 extends at an inclination angle opposite to that of the inclined plate 23 .

Through this design, the front of the storage collection box 7 has a larger opening, which can effectively collect the garbage transported by the second filter plate 3, significantly improving the efficiency and stability of the garbage interception and processing device, ensuring that the garbage interception and processing device can operate reliably for a long time, thereby better meeting the needs of garbage interception and processing in water conservancy projects.

In a specific embodiment, referring to FIG. 1 , a water guide port 24 is provided below the support frame 22 , and a bevel plate 26 is fixedly mounted on the bottom inner wall of the water guide port 24 .

When the water flows through the water guide port 24 , a pressure difference is generated at both ends of the inclined plate 26 , thereby pressing down the support frame 22 , thereby ensuring the stability of the garbage interception and treatment device.

In a specific implementation, referring to FIG. 1 , a bridge plate 25 is provided between the two storage centralized boxes 7 .

The bridge deck 25 provides a stable transition platform, allowing maintenance personnel to move quickly and safely between the two storage boxes 7 without being disturbed by water flow or other factors, thereby saving time for inspection and maintenance, facilitating the execution of daily inspection and cleaning tasks, and ensuring that maintenance tasks can be completed in a timely and effective manner to ensure the continued operation of the water conservancy project and the effectiveness of environmental protection.
