Description

Technical Field

[0001] This invention relates to the field of environmental protection and cleaning in water conservancy and hydropower projects, and in particular to an automated recycling and treatment device and method for floating debris on the water surface in front of a dam. Background Technology

[0002] After the dam is completed, the reservoir will begin to store water. River debris (domestic waste, natural floating objects, etc.) will gradually accumulate in front of the dam under the action of water flow, which will have an adverse impact on the dam's navigation, drainage, and power generation facilities. Therefore, it is especially important to clean up floating objects on the water surface in a timely manner. At present, the main method is to block floating objects on the water surface by using debris barriers and to regularly clean them up by cleaning boats.

[0003] Because the debris-blocking flotation device has limited blocking capacity, it cannot block all floating objects on the water surface under the action of water flow. Using manual dredging and debris-clearing boats requires a lot of manpower and resources, resulting in low cleaning efficiency and high economic costs. Furthermore, manual operations in deeper waters pose certain safety risks. Summary of the Invention

It is easy to operate and facilitates retrieval and subsequent centralized treatment.

[0006] In a preferred embodiment, the transverse trash rack includes a transverse upper base and a transverse lower slide rail, with a transverse trash rack plate between the transverse upper base and the transverse lower slide rail. A transverse screw is provided on the upper side of the transverse upper base, and the transverse screw is driven by a transverse motor. A transverse moving nut is threadedly engaged with the transverse screw, and a transverse slide rail clamp is engaged with the transverse lower slide rail for sliding. The end of the vertical trash rack is connected to the transverse moving nut and the transverse slide rail clamp.

[0007] In a preferred embodiment, the vertical trash rack includes a vertical upper base and a vertical lower slide rail. A vertical trash rack plate is provided between the vertical upper base and the vertical lower slide rail. A vertical screw is provided on the upper side of the vertical upper base. The vertical screw is driven by a vertical motor. A horizontal trash rack plate is provided at the end of the vertical trash rack away from the horizontal trash rack. A vertical moving nut is threadedly engaged with the vertical screw. A vertical slide rail clamp is engaged with the vertical lower slide rail for sliding. The end of the horizontal trash rack plate is connected to the vertical moving nut and the vertical slide rail clamp.

[0008] In a preferred embodiment, the vertical trash rack is provided with a brush at one end near the horizontal trash rack and / or the horizontal trash rack is provided with a blade at the bottom of the horizontal trash rack.

[0009] In a preferred embodiment, a waste conveyor belt is provided on the top of the dam, and the waste conveyor belt is located below the guide plate.

[0010] In a preferred embodiment, a rinsing water gun is provided above the lifting conveyor belt, and the rinsing water gun is located above the retrieval box after the lifting conveyor belt is lifted to the upper end and turned upside down. Drainage holes are distributed on the guide plate.

[0011] In a preferred embodiment, a vibrator is provided at the upper end of the frame of the lifting conveyor belt.

[0012] In a preferred embodiment, a winch is provided on the dam, and a pulley guide rail is provided on the front side of the dam. The pulley block is slidably installed on the pulley guide rail, and the traction rope of the winch passes around the pulley block and is connected to the end of the vertical trash rack away from the horizontal trash rack.

[0013] In a preferred embodiment, the floating mechanism includes several floats, each float has a connecting ring around its perimeter, and a connecting shaft is inserted into the connecting rings of two adjacent floats to connect the two sets of floats.

[0014] The present invention also provides a method for recovering and treating floating debris on the water surface in front of a dam, comprising the following steps: Step 1: Horizontal and vertical trash racks intercept floating debris on the water surface in front of the dam. After a certain amount of floating debris is intercepted, the horizontal motors on the two sets of horizontal trash racks are started to drive the corresponding horizontal screws to rotate, so that the two sets of vertical trash racks move from both sides to the middle along the horizontal sliding rails, gradually gathering the scattered floating debris in front of the dam to the collection port in the middle of the dam. The horizontal motors are then turned off, and the vertical trash racks stop moving. Step 2: Turn on the vertical motors on the two sets of vertical trash racks to drive the vertical screws to rotate, causing the horizontal trash rack to move along the vertical sliding rails. This will collect the floating debris from the far end to the front of the retrieval mechanism. The horizontal trash rack continues to move, or the floating debris enters the retrieval box from the collection port under the action of the water flow. Start the retrieval lifting conveyor belt to lift the retrieval box upward. Step 3: After lifting the retrieval box to the top and turning it upside down, the lifting conveyor belt stops conveying. At this time, the upside-down retrieval box is located above the guide plate. The guide plate guides the floating objects and conveys them to the garbage conveyor belt. The garbage conveyor belt then conveys the cleaned floating objects to the next process. Step 4: The motor drives the rotating shaft to rotate, flipping the guide plate to a vertical position. The retrieval and lifting conveyor belt continues to run for conveying. Then, the motor is started to drive the rotating shaft to flip the guide plate to an inclined position, preparing for the next set of retrieval boxes to guide the material. Step 5: Repeat steps 3 and 4 until all floating debris is cleared. Stop the retrieval and lifting conveyor belt, then reset the vertical and horizontal debris barriers to their original positions to intercept floating debris, preparing for the next cleanup.

[0015] The present invention provides an automated recycling and treatment device and method for floating debris on the water surface in front of a dam, which has the following beneficial effects: 1. The horizontal and vertical debris barriers together form a debris-blocking mechanism to intercept floating debris. Under the action of water flow, the floating debris enters the retrieval box of the retrieval mechanism from the collection port. When it is necessary to clean up the floating debris, simply activate the retrieval mechanism to retrieve the floating debris.

[0016] 2. The set material guiding mechanism can guide the floating objects poured out of the retrieval box after lifting and tilting, so that they slide down to the garbage conveyor belt, which facilitates the transfer of floating objects.

[0017] 3. The horizontal screw is driven by the horizontal motor to rotate, which makes the vertical trash racks move along the horizontal sliding rail. This allows the two sets of vertical trash racks to move towards each other, which can drive floating objects toward the collection port in the middle of the two sets of horizontal trash racks, which is beneficial for the collection of floating objects.

[0018] 4. After the two sets of vertical debris barriers move towards each other, they then move towards the horizontal debris barrier via the horizontal debris barrier mesh. This helps to drive the floating debris towards the collection port, which is beneficial for the collection of the floating debris.

[0019] 5. The device uses automated collection and cleaning, which can effectively clean up scattered floating objects on the water surface in front of the dam. It is simple to operate and has low safety risks. Attached Figure Description

Detailed Implementation

[0021] like Figures 1-7 As shown, an automated floating debris recovery and treatment device for water surface in front of a dam includes two sets of floating mechanisms 2 floating on the front side of the dam 1. A horizontal debris barrier 5 is connected to the front side of the floating mechanism 2 via a connecting rod 4. The horizontal debris barrier 5 is arranged parallel to the dam body. A vertical debris barrier 7 is provided at the end of the horizontal debris barrier 5 away from the collection port, and the vertical debris barrier 7 is arranged perpendicular to the horizontal debris barrier 5. A collection port is formed between the two sets of floating mechanisms 2, and a retrieval mechanism 3 is provided at the collection port. In this embodiment, the floating mechanism 2 includes several floats 201, which are connected to form a whole to constitute the floating mechanism. Specifically, connecting rings 202 are provided around the floats 201, and connecting shafts 203 are simultaneously inserted into the adjacent connecting rings 202 of the two sets of floats 201 to connect the two sets of floats 201.

[0022] like Figure 5 As shown, the salvage mechanism 3 includes a salvage lifting conveyor belt 301. The lifting conveyor belt 301 is provided with salvage boxes 302 with hollow bottoms at intervals to facilitate drainage. The lower end of the salvage lifting conveyor belt 301 is installed below the water surface. The salvage lifting conveyor belt 301 lifts the salvage boxes 302 upwards. After being lifted to the top, the salvage boxes 302 are flipped and inverted to pour out the floating objects cleaned in the salvage boxes 302, thereby realizing the transfer of floating objects.

[0023] A material guiding mechanism 6 is provided on the top of the dam. The material guiding mechanism 6 includes a material guiding plate 601. A rotating shaft 602 is provided at the bottom of the lower end of the material guiding plate 601. The rotating shaft 602 is rotatably mounted on two sets of support seats 603 through bearings. The rotating shaft 602 is driven by a motor. The lifting conveyor belt 301 lifts the retrieval box 302 to the upper end and flips it upside down. The upside-down retrieval box 302 is located above the material guiding plate 601. The material guiding plate 601 facilitates the guiding of the poured-out floating objects.

[0024] Preferably, a flushing water gun 9 is provided above the lifting conveyor belt 301. The flushing water gun 9 is a high-pressure water gun, which is connected to the water source in front of the dam through a water pipe and a water pump. The flushing water gun 9 is located above the retrieval box 302 after the lifting conveyor belt 301 is lifted to the upper end and turned upside down. Drainage holes 604 are distributed on the guide plate 601.

[0025] After the retrieval box 302 is lifted, flipped, and inverted, the retrieved floating objects fall onto the guide plate 601. To reduce the amount of floating objects remaining in the retrieval box 302, the flushing water gun 9 is turned on to rinse the bottom of the retrieval box 302, which helps to clean the floating objects remaining in the retrieval box 302 onto the guide plate 601. The guide plate 601 has drainage holes 604 distributed on it to drain water during the material guiding process.

[0026] Preferably, a vibrator 16 is provided at the upper end of the frame of the lifting conveyor belt 301. By setting the vibrator 16, after a certain group of retrieval boxes 302 is lifted, flipped, and inverted, the vibrator 16 is turned on, which helps the floating objects in the retrieval box 302 to fall off.

[0027] In practical use, the top of the dam 1 is equipped with a garbage conveyor belt 8, which is located below the end of the guide plate 601 away from the retrieval mechanism 3. The garbage conveyor belt 8 transports the retrieved floating objects to the floating object treatment system for processing. Specifically, it includes a dehydration and drying room, a crushing room, and a screening and compression room arranged in sequence. The garbage conveyor belt 8 transports the floating objects to the dehydration and drying room for drying, and then into the crushing room to crush the large floating objects. The processed floating objects are then transported to the screening and compression room, where they are screened and compressed according to different types and then recycled.

[0028] The horizontal debris barrier 5 and the vertical debris barrier 7 together form a debris-blocking mechanism to intercept floating objects. Under the action of water flow, the floating objects enter the retrieval box 302 of the retrieval mechanism 3 from the collection port. When it is necessary to clean up the floating objects, simply start the retrieval mechanism to retrieve them.

[0029] Preferably, the transverse trash rack 5 includes a transverse upper base 501 and a transverse lower slide rail 502. A transverse trash rack plate 503 is provided between the transverse upper base 501 and the transverse lower slide rail 502. A transverse screw 504 is provided on the upper side of the transverse upper base 501. The end of the transverse screw 504 is rotatably mounted on a support seat through a bearing. The support seat is mounted on the transverse upper base 501. The transverse screw 504 is driven by a transverse motor 505. A transverse moving nut 506 is threadedly engaged with the transverse screw 504. A transverse slide rail clamp 507 is engaged with the transverse lower slide rail 502 for sliding. The upper and lower sides of the vertical trash rack 7 are respectively connected to the transverse moving nut 506 and the transverse slide rail clamp 507.

[0030] The horizontal motor 505 drives the horizontal screw 504 to rotate. Since the horizontal moving nut 506 is threadedly engaged with the horizontal screw 504, the vertical trash rack 7 moves along the horizontal sliding rail 502, realizing that the vertical trash rack 7 moves along the length direction of the horizontal trash rack 5. This allows the two sets of vertical trash racks 7 to move towards each other, which can move floating objects to the collection port in the middle of the two sets of horizontal trash racks 5, which is beneficial for the collection of floating objects.

[0031] Furthermore, the vertical debris barrier 7 includes a vertical upper base 701 and a vertical lower slide rail 702. A vertical debris barrier plate 703 is provided between the vertical upper base 701 and the vertical lower slide rail 702. A vertical screw 704 is provided on the upper side of the vertical upper base 701. The vertical screw 704 is rotatably mounted on the support base and is driven by a vertical motor 705. A horizontal debris barrier mesh 10 is provided at the end of the vertical debris barrier 7 away from the horizontal debris barrier 5. The horizontal debris barrier mesh 10 is set parallel to the horizontal debris barrier 5 and its length is less than the length of the horizontal debris barrier 5, so that floating objects can enter the front side of the horizontal debris barrier 5. A vertical moving nut 706 is threadedly engaged with the vertical screw 704. A vertical slide rail clamp 707 is engaged with the vertical lower slide rail 702 for sliding. The end of the horizontal debris barrier mesh 10 is connected to the vertical moving nut 706 and the vertical slide rail clamp 707.

[0032] The vertical motor 705 drives the vertical screw 704 to rotate. Since the vertical moving nut 706 is threadedly engaged with the vertical screw 704, the horizontal debris barrier 10 moves along the vertical sliding rail 702, thus moving the horizontal debris barrier 10 along the length of the vertical debris barrier 7. After the two sets of vertical debris barriers 7 move towards each other, the ends of the horizontal debris barrier 10 contact each other. Then, the horizontal debris barrier 10 moves towards the horizontal debris barrier 5, which helps to drive floating objects towards the collection port and facilitates the collection of floating objects.

[0033] Preferably, a brush 11 is provided at one end of the vertical debris barrier 7 near the horizontal debris barrier 5 or / and at one end of the horizontal debris barrier mesh 10 near the vertical debris barrier 7.

[0034] As the vertical debris barrier 7 moves relative to the horizontal debris barrier 5, the brush 11 can simultaneously clean the floating debris adhering to the horizontal debris barrier 5. As the horizontal debris barrier 10 moves along the vertical debris barrier 7, the brush 11 at the end of the horizontal debris barrier 10 can simultaneously clean the vertical debris barrier 7.

[0035] The bottom of the horizontal debris barrier 10 is equipped with blades 12. When the horizontal debris barrier 10 moves, the blades 12 can cut aquatic plants and branches, reducing the entanglement of floating debris.

[0036] Preferably, the dam 1 is equipped with a winch 13, the traction rope of the winch 13 is connected to the end of the vertical trash rack 7 away from the horizontal trash rack 5, the front side of the dam 1 is equipped with a pulley guide rail 14, the pulley guide rail 14 is arranged parallel to the horizontal trash rack 5, the pulley block 15 is slidably installed on the pulley guide rail 14, and the traction rope of the winch 13 is connected to the vertical trash rack 7 after passing through the pulley block 15.

[0037] After the cleaning is completed, the winch 13 on the top of the dam is started to lift the vertical trash rack 7 to above the water surface by pulling the steel rope. Then, the horizontal motor 505 is turned on to drive the horizontal screw 504 to rotate in the opposite direction, so that the two sets of vertical trash racks 7 move away from each other to reset. During the movement of the vertical trash racks 7, the pulley block 15 moves synchronously along the pulley guide rail 14 without affecting the movement of the vertical trash racks 7.

[0038] A method for recovering and treating floating debris on the water surface in front of a dam includes the following steps: Step 1: The horizontal trash racks 5 and vertical trash racks 7 intercept floating debris on the water surface in front of the dam. After a certain amount of floating debris is intercepted, the horizontal motors 505 on the two sets of horizontal trash racks 5 are started to drive the corresponding horizontal screws 504 to rotate, so that the two sets of vertical trash racks 7 move from both sides to the middle along the horizontal sliding rails 502, gradually gathering the scattered floating debris in front of the dam to the collection port position in the middle of the dam. The horizontal motors 505 are turned off, and the vertical trash racks 7 stop moving.

[0039] Step 2: Turn on the vertical motors 705 on the two sets of vertical debris barriers 7 to drive the vertical screws 704 to rotate, so that the horizontal debris barrier 10 moves along the vertical sliding rail 702, collecting the floating objects from the far end to the front of the retrieval mechanism 3. The horizontal debris barrier 10 continues to move or, under the action of water flow, the floating objects enter the retrieval box 302 from the collection port. Start the retrieval lifting conveyor belt 301 to lift the retrieval box 302 upward.

[0040] Step 3: After lifting the retrieval box 302 to the top and turning it upside down, the lifting conveyor belt 301 stops conveying. At this time, the upside-down retrieval box 302 is located above the guide plate 601. The guide plate 601 guides the floating objects and conveys them to the garbage conveyor belt 8. The garbage conveyor belt 8 conveys the cleaned floating objects to the next process.

[0041] Step 4: The motor drives the rotating shaft 602 to rotate, flipping the guide plate 601 to a vertical position. The retrieval and lifting conveyor belt 301 continues to run for conveying. Then, the motor is started to drive the rotating shaft 602 to flip the guide plate 601 to an inclined position, preparing for the next set of retrieval boxes 302 to guide the material.

[0042] Step 5: Repeat steps 3 and 4 until all floating debris is cleared. Then, the retrieval and lifting conveyor belt 301 stops running, and the vertical debris barrier 7 and the horizontal debris barrier net 10 are reset and adjusted to the floating debris interception state to prepare for the next cleaning.

[0043] After the completion of various water conservancy dams, they will face the task of cleaning up floating debris on the water surface. This device has a simple structure and is easy to operate. Through mechanized control, it can automatically clean up floating debris in the area in front of the dam, reducing the economic cost and safety risks of manual operations.
