[0071] A construction method for garbage filtering for water conservancy projects based on energy and environmental engineering includes the above-mentioned garbage filtering structure for water conservancy projects, and the specific processing steps are as follows:

[0072] Step 1: When intercepting floating garbage, the air pump group can be started to deliver gas into the floating mechanism 7, and the buoyancy of the gas will lift the cleaning fence 5 to the water surface to intercept the floating objects;

[0073] Step 2: When salvaging, first start the telescopic mechanism 8, which will lift the garbage after it is extended. The telescopic mechanism 8 rises and transports the garbage through the rectangular opening into the sluice platform 1;

[0074] Step 3: When the telescopic mechanism 8 reaches the top of the trash rack 3, it contacts the trigger button 10. The trigger button 10 activates the arc-shaped rod 82 on the telescopic mechanism 8 through electrical connection to retract it, and simultaneously activates the horizontal drive assembly 91, which pushes the transport mechanism 9 toward the telescopic mechanism 8.

[0075] Step 4: After the arc rod 82 is retracted, the garbage slides toward the bottom through the inclined surface of the cleaning grid 5. At this time, the horizontal drive assembly 91 pushes the transport mechanism 9 to move to the bottom of the cleaning grid 5. The garbage falls onto the transport mechanism 9 and is transported away by the transport mechanism 9.

[0076] Step 5: When it is necessary to further salvage the garbage from the lake bottom, the personnel need to discharge the gas in the floating mechanism 7 through the pressure relief valve in advance, and then start the hydraulic telescopic rod 43 to push the power output shaft of the third servo motor 42 to engage with the threaded column 1011, driving it to move toward the bottom of the lake to salvage the garbage deep at the bottom of the lake.

[0077] Working principle of the present invention:

[0078] Refer to the instruction manual Figure 1-12 , the hydraulic telescopic rod 43 can drive the third servo motor 42 to engage or disengage with the threaded column 1011, which can achieve two different effects;

[0079] When engaged, the third servo motor 42 can be used to drive the telescopic mechanism 8 to move up and down, and the garbage can be salvaged by lifting the telescopic mechanism 8. After the gas in the airbag 72 is released, the hydraulic telescopic rod 43 can drive the telescopic mechanism 8 to the bottom of the lake to salvage the garbage at the bottom of the lake.

[0080] During separation, the gas is pressurized by the air pump assembly and then transported to the air bag 72 through the conduit 74. The buoyancy of the gas pushes the protection frame 6 and the cleaning grid 5 to float on the water surface. The inclined surface of the cleaning grid 5 intercepts floating objects, reducing the clogging of the trash rack 3.

[0081] Refer to the instruction manual Figure 1-12 During salvage, the second servo motor 81 is started, and when the power output shaft driving gear of the second servo motor 81 engages with the tooth groove at the bottom of the arc rod 82, the arc rod 82 is driven to extend and retract, and the garbage is lifted by the arc rod 82 to prevent the garbage from falling;

[0082] Refer to the instruction manual Figure 1-12 When the telescopic mechanism 8 rises, the gap between the telescopic mechanism 8 and the trash rack 3 is tightly fitted together, and the garbage stuck in the trash rack 3 is cleaned by the cleaning grid 5 and the scraper 51. The cleaned garbage falls onto the arc-shaped rod 82 due to the inclined surface of the cleaning grid 5.

[0083] Refer to the instruction manual Figure 1-12 When the garbage dropped on the arc rod 82 is transported into the sluice platform 1, it contacts the trigger button 10 through the cleaning gate 5, and the second servo motor 81 and the first servo motor 912 are started at the same time. After the first servo motor 912 pushes the transport mechanism 9 to the bottom of the cleaning gate 5, the second servo motor 81 drives the arc rod 82 to retract, so that the garbage on the arc rod 82 slides along the inclined surface of the cleaning gate 5 to the top of the transport mechanism 9, and the garbage is transported away by the transport mechanism 9.

[0084] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.

A method for constructing garbage filtration for a water conservancy project, comprising the garbage filtration structure for a water conservancy project according to any one of claims 1 to 5, characterized in that: The specific processing steps are as follows: Step 1: When intercepting floating garbage, the air pump group can be started to transport gas into the floating mechanism (7), and the cleaning fence (5) can be lifted to the water surface by the buoyancy of the gas to intercept the floating objects; Step 2: When salvaging, the telescopic mechanism (8) is first started, and the telescopic mechanism (8) is extended to lift the garbage, and the telescopic mechanism (8) rises, and the garbage is transported through the rectangular opening into the sluice platform (1); Step 3: When the telescopic mechanism (8) reaches the top of the trash rack (3), it contacts the trigger button (10). The trigger button (10) starts the arc rod (82) on the telescopic mechanism (8) to retract through electrical connection, and at the same time starts the horizontal drive component (91). The horizontal drive component (91) pushes the transport mechanism (9) to move in the direction of the telescopic mechanism (8); Step 4: After the arc rod (82) retracts, the garbage slides to the bottom through the inclined setting of the surface of the cleaning rack (5). At this time, the horizontal drive component (91) pushes the transport mechanism (9) to move to the bottom of the cleaning rack (5), and the garbage falls onto the transport mechanism (9). The garbage is transported away by the transport mechanism (9); Step 5: When it is further necessary to salvage the garbage at the bottom of the lake, the personnel need to discharge the gas in the floating mechanism (7) through the pressure relief valve in advance, and then start the hydraulic telescopic rod (43) to push the power output shaft of the third servo motor (42) to engage with the threaded column (1011), drive it to move to the bottom of the lake, and salvage the garbage deep at the bottom of the lake.
