Abstract
Description
Technical Field
[0001] This invention relates to the field of aquaculture technology, specifically to a photovoltaic power generation fish farm dredging device. Background Technology
[0002] In aquaculture, dredging equipment is needed to regularly clean the silt deposited at the bottom of the fish farm to ensure that farmed fish or seafood have more room to grow and to facilitate harvesting. Chinese patent CN215594191U discloses a dredging device for aquaculture. This technical solution uses two sets of motors to drive the dredging plate to perform dredging work. However, the operating cost is high, and if one set of motors is damaged, one side of the dredging plate is easily jammed, resulting in technical problems such as low transmission stability and easy damage to the equipment.
[0003] Chinese patent CN220565311U discloses a sludge removal device for aquaculture, including a mounting shell. Two sets of mounting shells are arranged parallel to each other. A connecting shell is fixedly connected between one side of each mounting shell. Fixing ears are fixedly connected to the rear ends of both sides of one end of each mounting shell. Connecting frames, each in an "L" shape, are respectively provided on one side of the rear end of each mounting shell. A sludge removal scraper is fixedly connected between the connecting frames. A transmission mechanism is provided inside the connecting shell. A movable adjustment structure is provided inside the mounting shell. Adjustment shafts are movably connected to the rear ends of both sides of the mounting shell. One side of each adjustment shaft extends through one side of the mounting shell into the interior of the connecting shell.
[0004] While the above solution avoids the problem of motor jamming, it cannot adapt to fishponds with irregular shapes. This is because the scraper can only move along the track, and the depth of the silt at the bottom of the fishpond varies, making it impossible to ensure that the silt is removed evenly. In addition, there may be unpredictable large rocks at the bottom of the fishpond. If the scraper is blocked by large rocks during the silt removal process, it is easy to damage the guide rail used to guide the scraper. Furthermore, the length of the guide rail cannot be freely extended or retracted according to actual needs. In order to improve resource utilization, existing fishponds often install photovoltaic panels. Due to the influence of photovoltaic panels, the height of traditional silt removal devices is limited, and using traditional silt removal devices is prone to collisions with photovoltaic panels. Summary of the Invention
[0005] To address the aforementioned issues, a photovoltaic power generation fish farm dredging device is provided. This device comprises a dredging unit and two traction devices positioned on either side of the dredging unit. During operation, workers place the two traction devices on opposite banks of the fish farm, and then lay a traction rope between them. The traction rope must pass under the photovoltaic panels in the fish farm, and the total length of the rope between the two devices is adjusted to ensure that the dredging device, pulled by the rope, does not collide with the photovoltaic panels during movement. This allows the dredging device to effectively dredge the silt at the bottom of the fish farm in areas with photovoltaic panels, without being affected by the height of the photovoltaic panels during dredging.
[0006] To address the problems of existing technologies, this invention provides a photovoltaic power generation fish farm dredging device, comprising a dredging unit for dredging and two traction devices respectively disposed on both sides of the dredging unit. A traction rope is provided between the two traction devices for fixing the dredging unit and driving the dredging unit to move. The traction devices move the dredging device along the extension direction of the traction rope by traction through the traction rope. When the traction rope drives the dredging device to move, it passes under the photovoltaic power generation panel disposed in the fish farm.
[0007] Preferably, the two traction devices operate synchronously, with one traction device releasing the traction rope and the other traction device retracting the traction rope at the same speed as the released traction rope.
[0008] Preferably, the dredging unit includes a shovel device, which is equipped with a shovel located at the bottom of the shovel device. When the bottom of the shovel is tilted downward, the shovel is in the dredging state. The tip of the shovel is inserted into the silt and shovels the silt at the bottom of the fish farm with the traction of the traction device. When the bottom of the shovel is tilted upward, the shovel is in the silt collection state. The shovel completes the switching between the dredging state and the silt collection state by rotating itself.
[0009] Preferably, when the shovel in the shovel removal device is in the dredging state, the shovel can be inserted vertically into the silt of the fishery under its own weight and rise and fall vertically with the terrain of the bottom of the fishery under the traction of the traction device.
[0010] Preferably, the dredging unit also includes a lifting device for controlling the raising and lowering of the shovel. The lifting device is equipped with a hoisting rope for hoisting the shovel. The lifting device controls the shovel to move vertically through the hoisting rope. When the hoisting rope is fully extended, the shovel is in the dredging state.
[0011] Preferably, the dredging unit also includes a stone cleaning device, which is inclined to the front side of the tip of the shovel. When the traction device pulls the shovel to move, the cleaning end of the stone cleaning device cleans the stones at the front end of the shovel.
[0012] Preferably, one side of the stone removal device is provided with an adjustment device for changing the tilt angle of the stone removal device. When the cleaning end of the cleaning device is close to the slope of the fishery, the adjustment device drives the stone removal device to rotate as a whole, so that the cleaning end of the cleaning device rotates and rises from the front of the shovel device to a horizontal state.
[0013] Preferably, a rotating device is provided on one side of the shovel for driving the shovel to rotate, and the rotating device drives the shovel to rotate so that the shovel can switch between dredging state and sludge collection state.
[0014] Preferably, a locking device is provided on one side of the rotating device for locking the shovel in the dredging state.
[0015] Preferably, when the shovel is pulled to the slope of the fishery by the traction device, the shovel in the shovel switches from the silt collection state to the dredging state, and the bottom of the shovel tilts downward to discharge the silt stored in the shovel.
[0016] The advantages of this invention compared to the prior art are:
[0017] 1. This invention, through the setting of a dredging unit and two traction devices respectively set on both sides of the dredging unit, allows workers to set the two traction devices on both banks of the fishery during use. Then, a traction rope is laid between the two traction devices. When laying the traction rope, it is necessary to ensure that the traction rope passes under the photovoltaic panels of the fishery, and the total length of the traction rope between the two traction devices is adjusted to ensure that the dredging device, pulled by the traction rope, will not collide with the photovoltaic panels during movement. This allows the dredging device to dredge the silt at the bottom of the fishery in fishery with photovoltaic panels, without being affected by the height of the photovoltaic panels during dredging.
[0018] 2. By setting up a lifting device, the lifting device fully releases the hoisting rope before the shovel switches to the dredging state, allowing the shovel to adapt to the terrain at the bottom of the fishery by its own weight, thereby improving the shovel's dredging ability.

[0032] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0033] Reference Figure 1 and Figure 2 A photovoltaic power generation fish farm dredging device includes a dredging unit 1 for dredging and two traction devices 2 respectively arranged on both sides of the dredging unit 1. A traction rope 21 is provided between the two traction devices 2 for fixing the dredging unit 1 and driving the dredging unit 1 to move. The traction device 2 is pulled by the traction rope 21 to move the dredging device along the extension direction of the traction rope 21. When the traction rope 21 drives the dredging device to move, it passes under the photovoltaic power generation panel 3 set in the fish farm.
[0034] Because the towing rope 21 is flexible, during use, the staff sets up two towing devices 2 on both banks of the fishery, and then sets up the towing rope 21 between the two towing devices 2. When setting up the towing rope 21, it is necessary to make the towing rope 21 pass under the photovoltaic power generation panel 3 in the fishery, and adjust the total length of the towing rope 21 between the two towing devices 2 to ensure that the dredging device pulled by the towing rope 21 will not hit the photovoltaic power generation panel 3 during the movement. In this way, the dredging device can dredge the silt at the bottom of the fishery in the fishery with photovoltaic power generation panels 3, and will not be affected by the height of the photovoltaic power generation panel 3 during dredging, that is, it will not collide with the photovoltaic power generation panel 3.
[0035] Reference Figure 1 and Figure 2 Two traction devices 2 operate synchronously. One traction device 2 releases the traction rope 21, and the other traction device 2 retracts the traction rope 21 at the same speed as the release speed of the traction rope 21.
[0036] Synchronizing the winding and unwinding speeds of the two traction devices 2 ensures that the height of the dredging unit 1 remains consistent as it moves along the traction rope 21. If the winding and unwinding speeds of the two traction devices 2 for the traction rope 21 differ, the following situation will occur: when the winding speed of the traction device 2 used to wind up the traction rope 21 is faster than the unwinding speed of the traction device 2 used to unwind the traction rope 21, the total length of the traction rope 21 used to pull the dredging unit 1 between the two traction devices 2 will be shortened. This will cause the height of the dredging unit 1 to increase, thus reducing its dredging performance. Furthermore, the dredging unit 1 may experience [further issues]. 1. If the photovoltaic panel 3 is hit during the pulling process of the traction rope 21, conversely, if the winding speed of the traction device 2 used to wind up the traction rope 21 is slower than the release speed of the traction device 2 used to release the traction rope 21, the total length of the traction rope 21 used to pull the dredging unit 1 between the two traction devices 2 will be extended. Under the action of the gravity of the dredging unit 1, the dredging unit 1 pulls the traction rope 21 to lower. Therefore, when the dredging unit 1 is inserted too deeply into the bottom of the fishery, the traction device 2 will be subject to greater resistance during the pulling process, which may lead to damage to the traction device 2 or breakage of the traction rope 21.
[0037] Reference Figure 2 , Figure 3 , Figure 10 and Figure 11 The dredging unit 1 includes a shovel 11, which contains a shovel 111 located at the bottom. When the bottom of the shovel 111 is tilted downwards, it is in the dredging state. The tip of the shovel 111 is inserted into the silt and, with the traction of the traction device 2, shovels the silt at the bottom of the fish farm. When the bottom of the shovel 111 is tilted upwards, it is in the silt collection state. The shovel 111 switches between the dredging state and the silt collection state by rotating itself.
[0038] A housing 12 is fitted around the shovel removal device 11. A guide groove 121 is vertically formed on the side wall of the housing 12. The extension direction of the guide groove 121 is parallel to the height direction of the housing 12. A guide block 122 is slidably disposed in the guide groove 121 along the extension direction of the guide groove 121. An arc-shaped groove 123 is provided on the side of the guide block 122 facing the shovel 111. An arc-shaped guide rail 124 is fixedly disposed on the end of the shovel 111 facing the guide block 122. The arc-shaped guide rail 124 is slidably disposed in the arc-shaped groove 123 along the extension direction of the arc-shaped groove 123. The center of the arc-shaped guide rail 124 and the center of the arc-shaped groove 123 are concentric. A lifting plate 125 is horizontally fixedly disposed on the upper part of the guide block 122. The lifting plate 125 is slidably disposed in the housing 12 along the height direction of the housing 12. The shovel removal device 11 can move along the height direction of the housing 12. The shovel removal device 11 rises and falls synchronously with the guide block 122 under the guidance of the guide groove 121.
[0039] Reference Figures 1-3 When the shovel 111 in the shovel removal device 11 is in the dredging state, the shovel 111 can be inserted vertically into the silt of the fishery under its own weight and rise and fall vertically with the terrain of the bottom of the fishery under the traction of the traction device 2.
[0040] When the two traction devices 2 are set on the two banks of the fishery, the traction device 2 pulls the dredging unit 1 to the middle of the fishery and moves it from one bank to the other. During the movement of the dredging unit 1, the upper part of the shovel 111 in the dredging unit 1 has no traction force. The shovel 111 is inserted into the silt at the bottom of the fishery under its own weight. With the traction of the traction device 2, the tip of the shovel 111 can rise and fall synchronously with the undulation of the bottom of the fishery, ensuring that the shovel 111 can remove the silt at the bottom of the fishery more thoroughly.
[0041] Reference Figure 2 , Figure 7 and Figure 10 The dredging unit 1 also includes a lifting device 13 for controlling the lifting and lowering of the shovel 11. The lifting device 13 is equipped with a hoisting rope 131 for hoisting the shovel 11. The lifting device 13 controls the shovel 11 to move vertically through the hoisting rope 131. When the hoisting rope 131 is fully extended, the shovel 111 is in the dredging state.
[0042] The lifting device 13 also includes an electric hoist 132. A hoisting rope 131 is wound within the electric hoist 132. The end of the hoisting rope 131 furthest from the electric hoist 132 is fixedly connected to the upper part of a lifting plate 125. The lifting plate 125 is also fixedly connected to the upper part of a guide block 122. The shoveling device 11 can move synchronously with the guide block 122. When the electric hoist 132 winds up or releases the hoisting rope 131, it can drive the shoveling device 11 to move up and down synchronously via the hoisting rope 131. Before the shoveling device 11 has moved above the fishpond... The hoisting rope 131 is wound up, and the shovel device 11 is at its highest position. The shovel device 11 is located inside the outer casing. After the shovel device 11 moves to above the fish farm under the traction of the traction device 2, the electric hoist 132 lowers the shovel device 11 by releasing the hoisting rope 131. The length of the released hoisting rope 131 is the same as the total length of the guide groove 121. This is called the complete release of the hoisting rope 131. It is worth noting that the shovel device 11 can move up and down synchronously with the guide block 122 under the guidance of the guide groove 121. Under the constraint of the guide groove 121, the shovel 11 has an upper stop position and a lower stop position. When the hoisting rope 131 is fully retracted in the electric hoist 132, the shovel 11 is in the upper stop position. When the hoisting is fully released, and there are no obstructions under the shovel 11, the shovel 11 can move to the lower stop position. However, in the actual shoveling process, the shovel 11 cannot reach the lower stop position. That is, when the shovel 11 is shoveling silt in the fishery, the shovel 11 has not yet descended to the lower stop position. The shovel 111 in device 11 is inserted into the silt in the fish farm and stops descending. Thus, when the bottom of the fish farm is depressed while the traction device 2 is pulling the shovel 11, the shovel 11 can continue to descend under its own weight. The hoisting rope 131 is fully released at this time, so the shovel 11 can move freely within the stroke of the guide block 122. Similarly, when the bottom of the fish farm rises, the shovel 11 will be lifted up again, that is, the shovel 11 rises again.
[0043] Reference Figure 2 , Figure 4 and Figure 6 The dredging unit 1 also includes a stone cleaning device 14. The stone cleaning device 14 is inclined to the front side of the tip of the shovel 111. When the traction device 2 pulls the shovel 11 to move, the cleaning end of the stone cleaning device 14 cleans the stones at the front end of the shovel 111.
[0044] The stone removal device 14 clears stones ahead of the shovel removal device 11 during its movement, preventing the shovel 111 from colliding with stones while shoveling silt at the bottom of the fishpond. This avoids a sudden increase in the traction load of the traction device 2, which could easily damage the traction device 2 and cause the traction rope 21 to break. The stone removal device 14 includes a first rotary drive 141, a synchronous pulley 142, a synchronous belt 143, an extension frame 144, a cleaning shaft 145, and cleaning claws 146. One end of the extension frame 144 is rotatably mounted on the guide block 122, and the connection between the extension frame 144 and the guide block 122 is located on the outside of the outer casing. The cleaning shaft 145 is rotatably mounted on the end of the extension frame 144 away from the guide block 122 along the thickness direction of the guide block 122. Multiple cleaning claws 146 are provided and are evenly fixed around the axis of the cleaning shaft 145. Two synchronous pulleys 142 are provided on the cleaning shaft 145. The two synchronous pulleys 142 are respectively provided on the side wall of the extension frame 144 along the extension direction of the extension frame 144. One of the synchronous pulleys 142 is provided at the end of the cleaning shaft 145 and rotates coaxially with the cleaning shaft 145. The synchronous belt 143 is sleeved on the two synchronous pulleys 142. The synchronous pulleys 142 and the synchronous belt 143 are in transmission cooperation. The first rotary driver 141 is provided at the end of the synchronous pulley 142 connected to the cleaning shaft 145. The first rotary driver 141 drives the synchronous pulley 142 to rotate. The first rotary driver 141 is preferably a servo motor. When the first rotary driver 141 is started, the first rotary driver 141 drives the cleaning shaft 145 through the synchronous pulley 142 and the synchronous belt 143. The rotated cleaning shaft 145 drives the cleaning claw 146 to rotate, so that the cleaning claw 146 removes stones from the silt at the bottom of the fish farm.
[0045] Reference Figure 5 and Figure 7 The stone cleaning device 14 is provided with an adjustment device 15 on one side for changing the tilt angle of the stone cleaning device 14. When the cleaning end of the cleaning device is close to the fishery slope 4, the adjustment device 15 drives the stone cleaning device 14 to rotate as a whole, so that the cleaning end of the cleaning device rotates and rises from the front of the shovel device 11 to a horizontal state.
[0046] An adjusting device 15 is located at the connection between the extension frame 144 and the guide block 122. The adjusting device 15 drives the extension frame 144 to rotate around the connection between the extension frame 144 and the guide block 122. During dredging, the adjusting device 15 adjusts the extension frame 144 to tilt downwards, causing the cleaning shaft 145, which is equipped with cleaning claws 146, to rotate and descend to the front end of the shovel 111. When the dredging unit 1 is about to reach the slope 4 of the fishery, the tilted extension frame 144 will obstruct the upward stroke of the dredging device as it rises from the bottom of the fishery to the bank of the slope 4. That is, during the process of the dredging device rising to the bank of the slope 4, the tilted extension frame 144 is prone to collide with the slope 4 and get stuck, thus preventing the dredging device from moving. After the adjusting device 15 drives the extension frame 144 to a horizontal state, the cleaning claws are installed. 146 can avoid the slope 4, allowing the dredging device to rise smoothly to the upper part of the slope 4. The adjusting device 15 includes a second rotary driver 151, a first gear 152 and a second gear 153. The first gear 152 is fixedly installed at the connection between the extension frame 144 and the guide block 122. The first gear 152 is fixedly connected to the end of the extension frame 144. The second gear 153 is rotatably installed on one side of the first gear 152. The first gear 152 and the second gear 153 mesh with each other. The second rotary driver 151 is installed on the second gear 153 and drives the second gear 153 to rotate. The second rotary driver 151 is preferably a servo motor. When it is necessary to drive the extension frame 144 to rotate, the second rotary driver 151 is started. The second rotary driver 151 drives the first gear 152 through the second gear 153, thereby causing the extension frame 144 to rotate.
[0047] Reference Figure 7 and Figure 8 A rotating device 112 is provided on one side of the shovel 111 to drive the shovel 111 to rotate. The rotating device 112 drives the shovel 111 to rotate, so that the shovel 111 can switch between the dredging state and the sludge collection state.
[0048] Before being placed in the fish farm for dredging, shovel 111 has its bottom tilted upwards. Before being placed in the fish farm for dredging, shovel 111 is driven by rotating device 112, causing it to rotate and its bottom to tilt downwards. Then, lifting device 13 fully releases the hoisting rope 131, and shovel 111 falls into the silt at the bottom of the fish farm under gravity. When shovel 111 is about to reach the slope 4 of the fish farm under the traction of traction device 2, it rotates... Device 112 drives the shovel 111 to rotate again, causing the bottom of the shovel 111 to tilt upwards. This allows the shovel 111 to catch the sludge it has scooped up. Traditional sludge-clearing shovels 111 cannot rotate, limiting the amount of sludge they can remove in a single pass. By rotating the shovel 111, the amount of sludge removed in a single pass is increased, thus improving dredging efficiency. When the bottom of the shovel 111 tilts downwards, it indicates that the shovel 111 is in the dredging state; when the bottom of the shovel 111 tilts upwards, it indicates that the shovel 111 is in the dredging state. This refers to the shovel 111 being in the sludge-collecting state. The rotating device 112 includes a third rotary actuator 1121, a third gear 1122, and meshing teeth 1123. The side of the shovel 111 facing the upper part of the outer shell has an arc-shaped structure. Meshing teeth 1123 are evenly distributed around the axis of the arc-shaped structure. The third gear 1122 is rotatably mounted on one side of the meshing teeth 1123, and the third gear 1122 meshes with the meshing teeth 1123. The third rotary actuator 1121 is mounted on the third gear. At the end of 1122, the third rotary actuator 1121 is located at the lower part of the lifting plate 125. The lower part of the lifting plate 125 is provided with a mounting bracket for mounting the third rotary actuator 1121. The third rotary actuator 1121 is preferably a servo motor. When the third rotary actuator 1121 is started, the third rotary actuator 1121 drives the shovel 111 with meshing teeth 1123 to rotate through the third gear 1122, so that the shovel 111 switches between the dredging state and the sludge collection state.
[0049] Reference Figures 7-9 A locking device 113 is provided on one side of the rotating device 112 for locking the shovel 111 in the dredging state.
[0050] After being locked by the locking device 113, when the shovel 111 is shoveling silt in the fish farm, the reaction force of the silt on the shovel 111 is absorbed by the locking device 113, avoiding damage to the rotating device 112 due to excessive force. The locking device 113 includes a pawl 1132, and ratchet teeth 1131 are evenly arranged on the arc-shaped structure of the shovel 111. The pawl 1132 and the ratchet teeth 1131 are engaged in a one-way locking fit. The pawl 1132 is electrically driven. When the shovel 111 is in the dredging state, the reaction force of the sludge on the shovel 111 is transmitted from the pawl 1132 and the ratchet 1131. The pawl 1132 abuts against the ratchet 1131, preventing the shovel 111 from rotating. When the shovel 111 needs to switch from the dredging state to the sludge collection state, the pawl 1132 rotates and lifts under the drive of electricity, and the rotating device 112 drives the shovel 111 to rotate, causing the bottom of the shovel 111 to tilt upward.
[0051] Reference Figures 1-11 When the shovel removal device 11 is pulled to the fishery slope 4 by the traction device 2, the shovel 111 in the shovel removal device 11 switches from the silt collection state to the silt removal state, the bottom of the shovel 111 tilts downward and discharges the silt stored in the shovel 111.
[0052] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
