Description

Technical Field

[0001] The present invention relates to the field of advanced environmental protection industry in energy-saving and environmental protection industry, specifically to special equipment for water pollution environmental protection and environmental protection engineering construction, and especially to a water conservancy project sluice auxiliary anti-blocking and pollution-clearing equipment and method. Background Art

[0002] Water conservancy projects are different types of hydraulic structures such as dams, dikes, spillways, sluices, channels, ferry canals, rafts, and fishways. This year, with the increase of people's environmental awareness, the awareness and operation methods of anti-blocking and pollution removal in water conservancy projects have been continuously improved. In water conservancy projects, the most serious problem is river blockage, which refers to the accumulation of deposits in the river, which hinders the smooth flow of water. This blockage may be caused by the continuous deposition of silt, suspended matter, plant residues, construction waste, etc. River blockage will limit the ability of the river to pass water, causing the water level to rise and the flood process to intensify, and will also destroy the river's ecosystem, thereby adversely affecting the survival and reproduction of fish and other aquatic organisms. At the same time, blocked rivers will also accumulate toxic and harmful substances, causing water pollution in downstream areas. In addition, river blockage will also lead to water shortages.

[0003] In recent years, the technology of using water conservancy projects to prevent blockage and clean up rivers has become more and more mature. The traditional method of preventing blockage and cleaning pollution generally uses a ship to load special anti-blockage and cleaning equipment for mobile large-scale cruise cleaning operations. This method requires the support of the ship and requires large-scale mobile operations, and the overall efficiency is low. In addition to the first time, there are some traditional methods of preventing blockage and cleaning pollution, such as: building cofferdams in sections of the river, and then draining and cleaning operations in sections. This method has a large overall engineering volume and is not suitable for cleaning operations in rivers. Other methods of preventing blockage and cleaning pollution are to use mechanical arms to dig and clean up with water. This method is not suitable for use in deep rivers. Some other siphon or winch methods require the installation of longer equipment on the river channel and the operation of larger auxiliary equipment on the outside of the river channel. It can be seen that traditional river channel anti-blocking and cleaning equipment and methods have some defects when used.

[0004] To sum up, in view of the shortcomings of the prior art, the present invention provides a water gate-assisted anti-blocking and pollution cleaning equipment and method for water conservancy projects which has a simple structure and is easy to operate. It utilizes a double-layer water gate to reduce the moving range of pollution cleaning and utilizes a double-layer water gate to achieve interception and separation. It has a high degree of automation, saves human resources, has high work and operation efficiency, has a wide range of applications, and has strong anti-blocking and pollution cleaning capabilities. It can effectively remove solid pollutants and implement crushing and recovery operations on solid impurities, which is beneficial to the protection of water resources. At the same time, it can quickly backfill water resources, filter out solid impurities while backfilling the filtered water source. The method is simple and easy to operate, and the water conservancy project water gate-assisted anti-blocking and pollution cleaning equipment and method have broad market prospects.

[0015] A method for preventing and cleaning pollution of a water conservancy project sluice auxiliary type anti-blocking and cleaning pollution device as described in any one of the above, wherein the method comprises:

[0016] S1. In the initial state, the upstream sluice gate is in the open state. When it is necessary to implement anti-blocking and pollution cleaning operations, the downstream sluice gate is opened, and the upstream water passes through the longitudinal filter screen and then the anti-blocking and pollution cleaning section and is discharged toward the downstream. After a specific period of time, the upstream sluice gate and the downstream sluice gate are closed at the same time;

[0017] S2, the anti-blocking and cleaning section isolated between the upstream sluice and the downstream sluice is filled with solid waste filtered by the longitudinal filter screen, the transmission motor is turned on, the transmission motor drives the transmission shaft in the worm gear to rotate, and further drives the crushing roller to rotate through the longitudinal transmission component;

[0018] S3. The crushing roller is initially located at the top of the longitudinal limit sliding groove. When the crushing operation is in progress, the winch is turned on to slowly operate the lifting rope. As the lifting rope is slowly unwound, the crushing blade of the worm gear on the outside of the longitudinal limit sliding block crushes the solids in the anti-blocking and cleaning section between the longitudinal filter screen and the upstream sluice gate and the solid garbage attached to the longitudinal filter screen. The crushing operation is accompanied by the lifting and lowering operation of the crushing roller. The solid garbage is crushed by reciprocating up and down motion and continuous crushing by the crushing roller until it is crushed to a size that can pass through the longitudinal filter screen.

[0019] S4, turning on the sewage suction pump, and using the sewage suction pump to suck the crushed fine particles that can pass through the longitudinal filter screen through the longitudinal sewage suction pipe to the transverse sewage discharge pipe, and then discharge them into the separation tank through the transverse sewage discharge pipe;

[0020] S5. The outlet of the horizontal sewage pipe is matched with the top of the filter tank. The sewage is discharged from the outlet of the horizontal sewage pipe into the filter tank. After being filtered by the longitudinal small-pore filter screen, the water source with solid particles removed flows into the reflow tank and returns to the downstream of the river through the clean water drainage pipe. When the solid particles in the filter tank reach the preset range, the sewage pipe is opened to discharge the solid particles to the external waste recycling and treatment device for recycling, and the longitudinal small-pore filter screen is cleaned.

[0021] The present invention has the following positive effects:

[0022] Firstly, the present invention utilizes a solid waste crushing device to implement segmented anti-blocking and pollution-cleaning treatment operations on solid waste in a river channel, utilizes two sluice gates arranged in parallel between a side wall and a middle wall to implement uninterrupted treatment, utilizes an upstream sluice gate normally open and a downstream sluice gate open to filter solid waste, isolates solid waste in the upstream direction of a large-pore longitudinal filter screen, and then closes the upstream and downstream sluice gates to form an independent anti-blocking and pollution-cleaning section, implements a separate crushing and treatment chamber for solid waste in the anti-blocking and pollution-cleaning section, and forms an independent isolation chamber when the treatment operation is running, which can prevent pollutants from leaking to the downstream or being remixed to the upstream.

[0023] Secondly, when crushing and processing the solid waste in the anti-blocking and pollution cleaning section, the present invention does not need to collect solid waste on a large scale. It only needs to control the opening and closing of upstream and downstream sluice gates to achieve self-collection of solid waste as the river water flows. When the self-collection of solid waste reaches the preset range value of the processing operation, an independent processing chamber is formed to implement closed processing. While processing, the solid waste can be crushed and sucked to the outside to implement solid-liquid separation. The separated liquid can use its own weight to quickly flow back to the downstream, avoiding the waste and loss of water resources.

[0024] Thirdly, when implementing the crushing operation, the inventor uses a crushing roller that can move up and down to perform reciprocating crushing operations in an independent anti-blocking and cleaning section until the particle size reaches a preset range and then passes through the longitudinal filter screen and is sucked out. In order to improve the crushing efficiency of the product, the present invention provides a receiving shear blade that cooperates with the crushing blade on the bottom surface of the crushing isolation cover, thereby improving the crushing effect and preventing the linear solid shell from being entangled on the crushing roller and causing the crushing operation to fail.

[0035] When the present invention performs the sluice-assisted anti-blocking and pollution-clearing operation of the water conservancy project, in the initial state, the upstream sluice 4 is in the open state. When the anti-blocking and pollution-clearing operation needs to be implemented, the downstream sluice 31 is opened, and the upstream water passes through the longitudinal filtering screen 21 and then passes through the anti-blocking and pollution-clearing section and is discharged toward the downstream. After a specific period of time, the upstream sluice 4 and the downstream sluice 31 are closed at the same time.

The length of each independent anti-blocking and pollution cleaning section shall not exceed 5 meters, and the width shall not exceed 5 meters, which is convenient for the effective crushing coverage of the crushing roller 33.
