Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to an automatic garbage collection device and method for environmental water conservancy projects. Background Technology

[0002] In the field of environmental water conservancy engineering, the cleanup of water bodies is a crucial link in ensuring the safe operation of water conservancy facilities, maintaining the ecological balance of water bodies, and improving the quality of the water environment. With the advancement of industrialization and urbanization, water pollution caused by garbage has become increasingly prominent. The types of garbage include floating solid waste and suspended debris. If not cleaned up in a timely manner, it can easily cause a series of problems such as blockage of water conservancy channels, sluice gate stagnation, and eutrophication of water bodies, seriously affecting the function of water conservancy projects and ecological environment safety.

[0003] Existing water conservancy waste cleaning devices are mainly divided into two categories: one is the traditional barrier net interception combined with manual retrieval. This mode requires manual inspection and retrieval of waste intercepted by the barrier net, which is not only labor-intensive and inefficient, but also poses significant safety hazards in harsh weather or deep water environments, making it difficult to meet the needs of large-scale, continuous waste cleaning; the other is mechanized cleaning devices, such as the patent with publication number CN220789679U, which discloses a water conservancy waste retrieval device. It uses a first rotating frame and a second rotating frame to drive the retrieval net to rotate and retrieval, and uses a retrieval net launcher to achieve long-distance cleaning, which improves the cleaning range. However, it has a core drawback: after the retrieval net catches the waste, it needs to be manually removed from the net before the next cleaning operation can be carried out. The manual operation is cumbersome, which seriously restricts the cleaning efficiency and cannot meet the needs of continuous cleaning. Summary of the Invention

[0027] Several buoyancy rods 36 are equidistantly distributed on the outer wall of the connecting rope 37. Anchor rods are provided at both ends of the connecting rope 37. A protrusion 39 is fixedly connected to one end of the buoyancy rod 36, and a positioning arc plate 38 is fixedly connected to the other end of the buoyancy rod 36.

[0028] The outer wall of the chain 32 is provided with a waterproof sleeve 31, which is fixedly connected to the outer wall of the barrier net 1. One end of the spiral conveyor rod 6 extends movably into the interior of the waterproof sleeve 31.

[0029] The top of the auxiliary gear plate 19 is rotatably connected to a protective cover 18, and the outer wall of the transmission rod 15 is rotatably sleeved with a limit collar 16.

[0032] The bottom shell of the lifting conveyor belt 4 is fixedly connected to the guide mesh plate 7, and the bottom shell of the lifting conveyor belt 4 is fixedly connected to the front side of the barrier mesh 1.

[0033] The outer wall of the transmission bevel gear 17 is provided with a protective sleeve, and the outer wall of the protective sleeve is fixedly connected to the outer wall of the housing of the lifting conveyor belt 4.

[0034] The outer walls of the screw conveyor 6 near both ends are rotatably connected to positioning shaft seats, which are fixedly connected to the front side of the barrier net 1.

[0035] In this embodiment, the conveying teeth 12 on the outer wall of the lifting conveyor belt 4 cooperate with the lifting plate 13 to enhance the ability to grab and convey garbage of different shapes. The cutting teeth 11 at the top of the garbage collection chamber 3 cooperate with the conveying teeth 12 to effectively cut off and separate the garbage wrapped on the conveying components, ensuring that the garbage falls accurately into the garbage collection chamber 3, thereby improving the stability and thoroughness of the conveying.

[0036] Driven by an electric push rod 41, the garbage pusher 40 inside the garbage collection chamber 3 can push and organize the garbage at the inlet into the collection chamber, effectively avoiding the blockage caused by the accumulation of garbage at the inlet; the inclined plate at the top of the garbage pusher 40 can guide the garbage to slide down smoothly, further improving the orderliness of garbage collection and reducing the frequency of manual sorting.

[0037] The movable connection between the extension crossbar 28 and the rotating sleeve 27, the cooperation between the C-shaped limiting ring 29 and the stroke positioning rod 30, combined with the elastic effect of the torsion spring, enable the arc-shaped agitator 26 to adapt to the resistance of different shaped garbage during the scraping process, avoiding jamming failure; the guide mesh plate 7 guides the movement of garbage towards the lifting conveyor belt 4, improving the efficiency of garbage approaching the conveying component; the reinforced support frame improves the structural stability of the barrier mesh 1 under the impact of water flow, and the positioning shaft seat ensures that the spiral conveying rod 6 rotates smoothly and reliably, enabling the device to adapt to complex aquatic environments.

[0038] The barrier net 1 is made of high-strength stainless steel with an anti-corrosion coating, which has good corrosion resistance and structural strength and can adapt to long-term immersion in water. The mesh size is designed to be 5-10mm according to the common garbage particle size.

[0039] The buoyancy rod 36 is made of high-density polyethylene (HDPE) and filled with polyurethane foam, which has excellent buoyancy performance and aging resistance, ensuring that it does not leak water and has stable buoyancy during long-term immersion. The buoyancy of a single buoyancy rod 36 can meet the water level self-adaptation requirements of the interception structure.

[0040] The lifting conveyor belt 4 is made of wear-resistant rubber material, with an embedded high-strength fiber skeleton to enhance tensile strength; the conveying teeth 12 and the lifting plate 13 are made of stainless steel and are fixedly connected to the lifting conveyor belt 4 through a vulcanization process, which makes the connection firm and wear-resistant, and can effectively grab various types of floating garbage.

[0041] The curved agitator teeth 26 are made of food-grade stainless steel with a smooth surface to avoid scratching aquatic organisms. They also have good corrosion resistance and structural strength. The curved tooth shape is designed to fit the trajectory of the debris scraping, reducing debris residue during the scraping process.

[0042] Both the waterproof housing 31 and the protective housing are made of engineering plastic (ABS), which has good waterproof and dustproof performance and structural strength. The interior is equipped with rubber sealing gaskets and is connected to the mounting base by bolts. The sealing level reaches IP68, which can effectively protect the internal chain 32, transmission gear 20 and other components from water and impurities.

[0043] The anchor rod is made of high-strength carbon steel with hot-dip galvanized anti-corrosion treatment. The bottom is equipped with a spiral drill rod structure, which is easy to insert into the bottom soil for stable fixation. The top is equipped with a hook structure, which can be detachably connected to the connecting rope 37 via a shackle, making it easy to install, disassemble and maintain the device.

[0044] The positioning rotary seat 23 is detachably connected to the fixed frame of the device via a flange. A rubber buffer pad is installed between the flange and the frame to reduce vibration transmission during rotation. A deep groove ball bearing is installed inside the positioning rotary seat 23 to ensure smooth rotation of the Z-shaped reciprocating swing rod 24 and reduce rotational resistance.

[0045] The torsion spring is made of spring steel and has stable elastic properties. One end of it is embedded in the slot of the extension crossbar 28 for fixation, and the other end is fixedly connected to the inner wall of the C-shaped limiting ring 29 to ensure that the C-shaped limiting ring 29 always has a preload in the direction of the travel positioning rod 30, so as to achieve reliable limiting.

[0046] The visual camera 5 is fixedly connected to the top of the barrier net 1 via an adjustable angle bracket. The bracket is made of aluminum alloy and can adjust the shooting angle of the camera according to monitoring needs. The camera is equipped with a waterproof and dustproof protective cover with a tempered glass light-transmitting window and an IP68 waterproof rating to ensure normal operation in harsh water environments. The protective cover is equipped with a heating and defogging device to prevent water mist from affecting the clarity of the image.

[0047] The reinforcement support frame is made of stainless steel square tubes welded into a triangular truss structure, which is stable and has a strong load-bearing capacity. One end is welded and fixed to the frame of the barrier net 1, and the other end is connected to the underwater concrete foundation or fixed pile through expansion bolts, which can effectively resist the impact of water flow and improve the installation stability of the barrier net 1.

[0048] The positioning shaft seat is made of cast iron and is detachably connected to the front frame of the barrier net 1 by anchor bolts. The shaft seat is equipped with a sliding bearing. The inner ring of the bearing is interference-fitted with the outer wall of the screw conveyor rod 6 to ensure that the screw conveyor rod 6 rotates smoothly and is reliably positioned, reducing radial runout during rotation.

[0049] An annular groove is provided at one end of the extension crossbar 28. A C-shaped limiting ring 29 is movably sleeved in the annular groove by a torsion spring. The opening size of the C-shaped limiting ring 29 is smaller than the diameter of the annular groove to prevent it from falling off. An arc-shaped contact surface is provided at the end of the C-shaped limiting ring 29 that abuts against the stroke positioning rod 30 to reduce wear during the limiting process and improve the limiting stability.

[0050] The stroke positioning rod 30 has a cylindrical structure, and its length can be adjusted according to the swing stroke requirements of the arc-shaped actuating tooth 26. When the Z-shaped reciprocating swing rod 24 drives the arc-shaped actuating tooth 26 to swing to the maximum stroke, the stroke positioning rod 30 abuts against the arc-shaped contact surface of the C-shaped limiting ring 29. The preload of the torsion spring achieves buffering and limiting, avoiding hard collisions that could damage the components and extending the service life of the components.

[0051] The rotating sleeve 27 is made of brass, which has good wear resistance. Its inner wall is fitted with the outer wall of the extension crossbar 28 with a clearance of 0.1-0.2mm to ensure that the rotating sleeve 27 can rotate flexibly. The two ends of the rotating sleeve 27 are equipped with annular retaining rings to prevent it from moving axially along the extension crossbar 28 and to ensure the stability when the mounting rod 25 drives the arc-shaped actuating tooth 26 to swing.

[0052] The controller 42 adopts a PLC controller, specifically the S7-200 SMART model, which has good stability and anti-interference capabilities. Its housing has a waterproof and sealed structure and is fixedly installed on the dry area of ​​the outer wall of the waste collection chamber 3. The controller 42 is equipped with a touch screen operating interface, which can display equipment operating status, waste collection volume, fault alarms, and other information in real time, and supports manual / automatic mode switching. The controller 42 is connected to the lifting motor 9, screw conveyor motor 35, electric push rod 41, and vision camera 5 through a waterproof cable. The cable interface uses a waterproof joint seal to ensure stable signal transmission and electrical safety. The controller 42 has a built-in waste volume recognition algorithm, which can determine the degree of waste accumulation based on the image data collected by the vision camera 5 and dynamically adjust the equipment operating parameters.

[0053] A drain outlet is installed at the bottom of the garbage collection chamber 3. A manual control valve is installed at the drain outlet to facilitate the regular discharge of water and small impurities from the collection chamber, reduce the odor caused by garbage rotting and deterioration, and reduce maintenance difficulty.

[0054] Example 2, as Figure 1 - Figure 9 As shown in Example 1, this invention provides an automatic waste disposal method for environmental water conservancy projects, comprising the following steps: Step 1: Installation of the device: Install the barrier net 1 vertically on the downstream side of the river channel, install the buoyancy interception component 2 at an acute angle to the riverbank, and fix the two ends of the connecting rope 37 to the barrier net 1 and the riverbank respectively through anchor rods.

[0055] Step 2: Triggering the start: When the visual camera 5 detects that the area covered by garbage on the river surface has reached the threshold, it sends a signal to the controller 42, and the controller 42 starts the lifting motor 9 and the screw conveyor motor 35.

[0056] Step 3: Waste conveying: The lifting motor 9 drives the lifting conveyor belt 4 to operate, and the waste intercepted by the barrier net 1 is conveyed upward through the conveying teeth 12 and the lifting plate 13; the screw conveyor motor 35 drives the screw conveyor rod 6 to send the waste near the barrier net 1 to the lifting conveyor belt 4.

[0057] Step 4: Waste scraping: The lifting motor 9, in conjunction with the waste scraping component 8, drives the arc-shaped agitator 26 to swing back and forth, scraping the waste onto the lifting conveyor belt 4 through adaptive angle adjustment, thereby reducing the reset resistance.

[0058] Step 5: Waste processing: The conveying teeth 12 and the cutting teeth 11 work together to shear and crush the waste, causing it to fall into the waste collection chamber 3; the controller 42 periodically starts the electric push rod 41 to push the waste push plate 40 to squeeze the waste in the collection chamber, and the inclined plate at the top of the waste push plate 40 guides the newly added waste.

[0059] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
