Description

Technical Field

[0001] This utility model relates to the technical field of cleaning and purifying water devices, and in particular to a cleaning and purifying water device for rice paddy crab farming. Background Technology

[0002] Rice-crab farming, as an important aquaculture model, has been widely promoted and applied in recent years. However, the cleanliness of the aquatic environment has a crucial impact on the growth and yield of rice-crabs. Due to the complex environment of rice-crab farming, there are often a large number of impurities such as weeds, uneaten feed, and mud in the water. These impurities not only affect the water quality but may also threaten the healthy growth of rice-crabs. Therefore, maintaining the cleanliness of the farming water is the key to ensuring the healthy growth of rice-crabs and increasing their yield.

[0003] In practical use, traditional cleaning boats are often limited by various factors such as water flow conditions and entanglement of impurities during movement, resulting in low movement efficiency and difficulty in quickly covering the entire aquaculture area for cleaning. At the same time, existing cleaning boats often lack effective impurity filtration and cleaning mechanisms during the cleaning and purification process, leading to poor cleaning results and easy blockage problems. Improvements are urgently needed to address these issues and improve the movement efficiency and cleaning and purification capabilities of cleaning boats.

[0004] Therefore, to address the aforementioned problems of hindering the improvement of the cleaning vessel's mobility and enhancing its cleaning and water purification capabilities, a cleaning and water purification device for rice-crab farming can be designed. First, the drive assembly generates thrust to move the cleaning vessel in the water. Simultaneously, the active motor starts, driving the active gear to rotate via the active shaft. The active gear meshes with the driven half-gear, thereby driving the driven shaft and its rotating block to rotate within a certain range. The rotating block not only carries the sealed chamber and its internal drive motor and propeller for reset and adjustment rotation, but also drives the two adjusting rods via connecting rods on both sides. The two adjusting rods further adjust the angle of the two guide tail fins via connecting shafts on both sides. The system is adjusted to adapt to different water flow conditions, enhancing the stability and maneuverability of the device. During the propulsion propeller rotation, the filter assembly prevents impurities from entangled or obstructing the rotation of the drive assembly, while the fixed brush continuously brushes the surface of the filter assembly, effectively removing adhering impurities, preventing blockages, and ensuring smooth water flow. In addition, the collection assembly effectively intercepts and collects impurities in the water. This series of driving, rotating, adjusting, and cleaning actions work together to not only improve the mobility of the cleaning vessel but also significantly enhance its ability to clean impurities and purify water in rice paddy crab farming areas, providing a cleaner and healthier growth environment for the rice paddy crabs.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 This utility model provides an embodiment: a water purification and cleaning device for rice paddy crab farming, comprising a cleaning boat 1, an active motor 2, an active shaft 3, an active gear 4, a driven half gear 5, a driven shaft 6, a rotating block 7, a fixed brush rod 8, a connecting rod 9, an adjusting rod 10, a connecting shaft 11, a guide tail fin 12, a limiting bracket 13, an adjusting groove 14, a drive assembly, a filter assembly, a protective assembly, and a collection assembly; two sets of protective assemblies are provided on both sides of the cleaning boat 1, and a limiting bracket 13 is provided on one side of the protective assembly. The two sets of limiting brackets 13 are located on both sides of the cleaning boat 1, and an adjusting groove 14 is opened at one end of the limiting bracket 13. A connecting shaft 11 is provided inside the adjusting groove 14, and a guide tail fin 12 is provided on the side wall of the connecting shaft 11. An active motor 2 is provided inside one side of the cleaning boat 1, and the output end of the active motor 2 is provided with a main... The drive shaft 3 has a drive gear 4 at one end. A driven shaft 6 is located inside one side of the cleaning vessel 1. A driven half gear 5 is located on the side wall of the driven shaft 6. The driven half gear 5 meshes with the drive gear 4. A rotating block 7 is located at the lower end of the driven shaft 6. A drive assembly is located on one side of the rotating block 7. A filter assembly is located on one side of the drive assembly. A fixed brush rod 8 is located outside the filter assembly. Both ends of the fixed brush rod 8 are fixedly connected to the side wall of the cleaning vessel 1. Two sets of connecting rods 9 are located on both sides of the rotating block 7. An adjusting rod 10 is located at one end of the connecting rod 9. One end of the adjusting rod 10 is rotatably connected to one end of the connecting rod 9. The other end of the adjusting rod 10 is fixedly connected to the lower end of the connecting shaft 11. The upper end of the connecting shaft 11 is rotatably connected to the inside of the limiting bracket 13. A collection assembly is located on the side wall of the limiting bracket 13.

[0023] Please see Figure 2The drive assembly includes a sealed chamber 101, a drive motor 102, and a drive shaft 103. A sealed chamber 101 is located on one side of the rotating block 7, and the drive motor 102 is housed inside the sealed chamber 101. The output end of the drive motor 102 is connected to the drive shaft 103. First, starting the drive motor 102 can drive the drive shaft 103 to rotate. The drive assembly also includes a propeller 104. One end of the drive shaft 103 is connected to the propeller 104, which is located at the stern of the cleaning vessel 1. After starting the drive motor 102, power is transmitted through the drive shaft 103. The force is transmitted to the propeller 104, causing it to rotate and generate a powerful thrust, thereby driving the cleaning vessel 1 forward in the water; the filtration assembly includes a filter cover 201; the filter cover 201 is provided on one side of the sealed chamber 101, the filter cover 201 is located outside the propeller 104, and the fixed brush rod 8 is located outside the filter cover 201; the filter cover 201 can effectively intercept and block impurities in the water during the movement of the vessel, preventing these impurities from entangled or hindering the rotation of the propeller 104, ensuring that the cleaning vessel 1 can perform cleaning tasks smoothly and efficiently in the water.

[0024] Please see Figures 3-4The protective assembly includes a fixed frame 301, a fixed rod 302, and an adjusting slider 303. Multiple fixed frames 301 are provided on both sides of the cleaning vessel 1. A fixed rod 302 is installed inside each fixed frame 301, and an adjusting slider 303 is installed on the side wall of the fixed rod 302. The adjusting slider 303 is slidably connected to the fixed rod 302. When the cleaning vessel 1 is operating in the water, if the limiting brackets 13 on both sides encounter accidental collisions with impurities in the water, the resulting impact force will be transmitted through the adjusting frames 305 on both sides to the adjusting sliders 303 inside the fixed frames 301. The protective assembly also includes adjusting springs 304 and adjusting frames 305. Two sets of adjusting springs 304 are provided on both sides of the adjusting slider 303. An adjusting frame 305 is installed outside the fixed frame 301. Both ends of the adjusting slider 303 are fixedly connected to the two sides of the adjusting frame 305. One side of the adjusting frame 305 is fixedly connected to the inner wall of the limiting bracket 13. Since the adjusting slider 303 is slidably connected to the fixed rod 302 and is equipped with adjusting springs 304 on both sides, the slider will slide and adjust accordingly on the fixed rod 302 according to the elastic characteristics of the spring. This process effectively disperses and absorbs the impact force generated by the collision, realizing buffer protection for the structures on both sides of the cleaning vessel 1, and ensuring the stable operation and safety of the hull. The collection component includes a pusher bracket 401 and a capture claw 402. The other end of the limiting bracket 13 is provided with a pusher bracket 401, and the side wall of the limiting bracket 13 is provided with a capture claw 402. Two sets of capture claws 402 are set on both sides of the cleaning vessel 1, and two sets of pusher brackets 401 are set at the front end of the cleaning vessel 1. When the cleaning vessel 1 is moving in the water, the pusher bracket 401 at the front end continuously pushes away and concentrates the impurities, while the capture claws 402 on both sides extend in time to firmly grab the impurities and bring them into the collection area of ​​the hull, thereby realizing the effective interception and collection of impurities in the water.

[0025] When the cleaning and water purification device is in use, the cleaning boat 1 is placed in the rice field crab farming environment. First, the drive motor 102 is started, and the power is transmitted to the propeller 104 through the drive shaft 103, which makes it rotate and generate a strong thrust, thereby driving the cleaning boat 1 forward in the water.

[0026] At the same time, the active motor 2 starts and drives the active gear 4 to rotate via the active shaft 3. The active gear 4 meshes with the driven half gear 5, thereby driving the driven shaft 6 and the rotating block 7 on it to rotate within a certain range. The rotating block 7 not only carries the sealed chamber 101 and the internal drive motor 102 and propeller 104 to reset and adjust the rotation, but also drives the two adjusting rods 10 on both sides through the connecting rods 9 on both sides. The two adjusting rods 10 on both sides further adjust the angle of the two guide tail fins 12 on both sides through the connecting shafts 11 on both sides to adapt to different water flow conditions and enhance the stability and operability of the device.

[0027] During the rotation of the propeller 104, the filter cover 201 can effectively intercept and block impurities in the water as the hull moves, preventing these impurities from entangled or hindering the rotation of the propeller 104, ensuring that the cleaning vessel 1 can perform cleaning tasks smoothly and efficiently in the water. Meanwhile, the fixed brush bar 8 continuously brushes the surface of the filter cover 201, effectively removing adhering impurities, preventing blockage, and ensuring smooth water flow.

[0028] In addition, when the cleaning vessel 1 is moving in the water, the front pusher bracket 401 continuously pushes away and concentrates the impurities, while the capture claws 402 on both sides extend in time to firmly grab the impurities and bring them into the collection area of ​​the vessel, thereby achieving effective interception and collection of impurities in the water.

[0029] The synergistic effect of this series of driving, rotating, adjusting and cleaning actions not only improves the mobility of the cleaning vessel 1, but also significantly enhances its ability to clean up debris and purify water in the rice paddy crab farming area, providing a cleaner and healthier growth environment for the rice paddy crabs.

[0030] Furthermore, when the cleaning vessel 1 is operating in the water, if the limiting brackets 13 on both sides encounter an accidental collision with impurities in the water, the resulting impact force will be transmitted through the adjusting frames 305 on both sides to the adjusting sliders 303 in the fixed frames 301 on both sides. Since the adjusting sliders 303 are slidably connected to the fixed rods 302 and are equipped with adjusting springs 304 on both sides, the sliders will slide and adjust accordingly on the fixed rods 302 according to the elastic characteristics of the springs. This process effectively disperses and absorbs the impact force generated by the collision, realizing buffer protection for the structure on both sides of the cleaning vessel 1, and ensuring the stable operation and safety of the hull.

[0031] Through the above steps, when the cleaning and water purification device is in use, the cleaning boat 1 is placed in the rice-crab farming environment. First, the drive assembly is started to generate thrust, causing the cleaning boat 1 to move in the water. At the same time, the active motor 2 starts, driving the active gear 4 to rotate via the active shaft 3. The active gear 4 meshes with the driven half gear 5, thereby driving the driven shaft 6 and its rotating block 7 to rotate within a certain range. The rotating block 7 not only carries the sealed chamber 101 and the internal drive motor 102 and propeller 104 for reset and adjustment rotation, but also drives the two adjusting rods 10 on both sides via the connecting rods 9 on both sides. The two adjusting rods 10 on both sides further drive the two guide tail fins 1 through the two connecting shafts 11 on both sides. The angle of the 2 is adjustable to adapt to different water flow conditions, enhancing the stability and maneuverability of the device. During the rotation of the propeller 104, the filter assembly prevents impurities from entangled or hindering the rotation of the drive assembly. Meanwhile, the fixed brush rod 8 continuously brushes the surface of the filter assembly, effectively removing adhering impurities, preventing blockages, and ensuring smooth water flow. In addition, the collection assembly effectively intercepts and collects impurities in the water. This series of driving, rotating, adjusting, and cleaning actions work together to not only improve the mobility of the cleaning vessel 1 but also significantly enhance its ability to clean impurities and purify water in rice paddy crab farming waters, providing a cleaner and healthier growth environment for rice paddy crabs.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
