[0032] Since the automatic turning device provided by the present invention is applied to fisheries, the turning bucket can also be called a fish bucket. When in use, when the empty fish bucket is rotated and placed on the bracket, due to the effect of the weight, the upper opening of the fish bucket is tilted toward the movable pendulum when it is empty. After entering the water, as the water level in the fish bucket gradually rises, the first float starts to work, and the mouth of the fish bucket gradually becomes straight from tilted, and becomes straight when it is close to being full of water. The fish bucket continues to move downward, and under the action of the first float, the fish bucket is driven to rotate. After it is completely submerged in the water, no matter how deep it is underwater, due to the dominant buoyancy of the first float, it only rotates about 90°, so it is turned 90° first to release the fish. At this time, the first float of the movable pendulum is at a commanding height, and the angle between the mouth of the fish bucket and the horizontal plane is close to 90°. Then the fish bucket is lifted, The fish bucket must be out of the water, the volume of the first float in the water is constantly decreasing, and the gravity of the weighted object and the first float gradually takes the leading role, so that the mobile pendulum continues to drive the fish bucket to rotate. When the fish bucket shaft approaches the water surface, the mobile pendulum is weighted and submerged in the water, and the first float floats on the water surface. The buoyancy generated by the first float contacting the water surface takes the leading role. The fish bucket has completely rotated above the water surface, and the angle between the fish bucket mouth and the water surface is about 180°. For the fish that still stay when turning 90° to release the fish, there will be a pouring effect at this time, pouring the fish, and then continue to lift the fish bucket upwards. The volume of the first float in the water is constantly decreasing, and the gravity of the weighted object and the first float gradually takes the leading role, so that the mobile pendulum continues to drive the fish bucket to rotate, and the fish bucket continues to rotate to the starting state. Since then, it has rotated about 360°, and the fish bucket contains water, which can be part of it or full of water.

[0033] Among them, after the angle between the mouth of the fish bucket and the water surface is about 180°, when the fish bucket continues to be lifted upward, the fish bucket flips over and enters the water to hold some water. Generally, it is not full for the first time after flipping. The speed of lifting the fish bucket is inversely proportional to the amount of water entering the fish bucket. The slower the speed of lifting the fish bucket, the more water is held in the fish bucket, and the faster the speed of lifting the fish bucket, the less water is held in the fish bucket.

[0034] The automatic flipping device provided by the present invention utilizes the effective design of the first float and the weighted object. From the time the fish bucket is filled with water and completely immersed in water to the time it is finally lifted up, it always rotates in one direction, from empty to full of water and then to empty. There is no strong electricity or strong magnetism in the prior art. The fish transfer can be completed only by its own mechanical structure, thus avoiding affecting the fish's navigation system and causing harm to the fish. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] The automatic flipping device provided in an embodiment of the present invention includes a flipping bucket 1, a movable pendulum, a first limit device 19 and a second limit device 20, wherein the movable pendulum includes a weight 12 and a first float 11, the first limit device 19 and the second limit device 20 are arranged at intervals on the inner wall of the same side of the flipping bucket 1, and the movable pendulum is rotatably arranged along the inner wall of the flipping bucket 1 and is clamped between the first limit device 19 and the second limit device 20.

[0059] Since the automatic turning device provided by the embodiment of the present invention is applied to the fishery, the turning bucket 1 can also be called a fish bucket. When in use, when the empty fish bucket is rotated and placed on the bracket, due to the action of the weighted object 12, the upper opening of the fish bucket is tilted toward the movable pendulum when it is empty. After entering the water, as the water level in the fish bucket gradually rises, the first float 11 begins to work, and the mouth of the fish bucket gradually becomes straight from tilted, and becomes straight when it is close to being full of water. The fish bucket continues to move downward, and under the action of the first float 11, the fish bucket is driven to rotate. After it is completely submerged in the water, no matter how deep it is underwater, since the buoyancy of the first float 11 is dominant, it only rotates about 90°. In order to flip 90° first to release the fish, the first float 11 of the movable pendulum rotates to the commanding height, and the angle between the mouth of the fish bucket and the horizontal plane is close to 90°. To lift the fish bucket again, it must be out of the water. The volume of the first float 11 in the water is constantly decreasing, and the weighted object 12 The weight of the first float 11 gradually takes the leading role, then mainly under the action of the weight 12, the mobile pendulum rotates downward, when the fish bucket shaft approaches the water surface, the weight 12 of the mobile pendulum is submerged in the water, the first float 11 floats on the water surface, the buoyancy generated by the first float 11 contacting the water surface takes the leading role, the fish bucket has completely rotated above the water surface, the angle between the fish bucket mouth and the water surface is about 180°, for the fish that still stays when turning 90° to release the fish, there will be a pouring effect at this time, pouring the fish, and then continue to lift the fish bucket upward, the volume of the first float 11 in the water continues to decrease, the weight 12 and the first float 11 gradually take the leading role, mainly under the action of the weight 12, the mobile pendulum continues to drive the fish bucket to rotate, the fish bucket continues to rotate downward, after rotating through the lowest point, the first float 11 takes the leading role, so that the fish bucket continues to rotate to the starting state. Since then, it has rotated about 360°, and the fish bucket contains water, which can be part of it or full of water.

[0060] Among them, after the angle between the mouth of the fish bucket and the water surface is about 180°, when the fish bucket continues to be lifted upward, the fish bucket flips over and enters the water to hold some water. Generally, it is not full for the first time after flipping. The speed of lifting the fish bucket is inversely proportional to the amount of water entering the fish bucket. The slower the speed of lifting the fish bucket, the more water is held in the fish bucket, and the faster the speed of lifting the fish bucket, the less water is held in the fish bucket.

[0061] In actual operation, it is usually hoped that there will be little water left in the fish bucket after a 360-degree rotation. To achieve this result, the lifting equipment adopts a variable speed design. The fish bucket is slowly placed in the water, and then the fish bucket is slowly lifted to the water surface. The fish bucket is quickly lifted after turning 180 degrees. After the fish bucket is turned over, the amount of water in the fish bucket is less. The fish bucket will then be transported back to the fish gathering point for secondary loading. Therefore, when there are fish in the fish bucket, the overall load of the fish bucket is large, it needs to be more stable, and the transportation process is slower; when there are no fish in the fish bucket, the overall load is small, it does not need to be stable, and the transportation process should be quick, so the weight of the fish bucket during the return process is as small as possible. At present, there are high technical requirements for transporting fish. If it exceeds a certain time, oxygenation equipment needs to be used; there are also requirements for the volume ratio of fish to water, etc. In short, the whole process must be fast and slow to meet the high requirements for transporting fish.

[0062] The automatic flipping device provided in the embodiment of the present invention utilizes the effective design of the first float 11 and the weight 12. From the time the fish bucket enters the water and is completely immersed in the water to the time it is finally lifted up, it always rotates in one direction, from empty to full of water and then to empty. There is no strong electricity or strong magnetism in the prior art. The fish transfer can be completed only by its own mechanical structure, thus avoiding affecting the fish's navigation system and causing harm to the fish.

[0063] Among them, the fish bucket has an eccentric design. Since the spherical fish bucket will generate buoyancy when entering the water, in order to reduce the force of the buoyancy of the water on the fish bucket and reduce the tilting of the fish bucket after entering the water, the volume of the fish bucket before entering the water is reduced by tilting the fish bucket.

[0064] When the mobile pendulum drives the tipping bucket 1 to tip over, there can be multiple specific implementations. In the first specific implementation, for example Figure 2As shown, a combination of a moving weight 12 and a slide rail 13 is adopted. The inner wall of the tipping bucket 1 is an arc-shaped inner wall, and the mobile pendulum also includes a slide rail 13 and a slider 14 used in conjunction with each other. Specifically, for example, a spring nail and a linear bearing are used in conjunction with each other. A cavity is provided inside the first floating body 11, and the weight 12 is built in the cavity. A slider 14 is provided at the bottom of the first floating body 11. A slide rail 13 is provided on the inner wall of the tipping bucket 1, and a first limiting device 19 and a second limiting device 20 are provided at both ends of the slide rail 13. When the mobile pendulum moves along the slide rail 13 to the first limiting device 19, the tipping bucket 1 is pushed to flip by pushing the first limiting device 19. Similarly, when the mobile pendulum moves along the slide rail 13 to the second limiting device 20, the tipping bucket 1 is pushed to flip in the opposite direction by pushing the second limiting device 20. When the slide rail 13 is used, the slide rail 13 itself can be a closed slide rail with its own first limiting device 19 and second limiting device 20. The weight 12 can be a plurality of ball bearings. When the fish bucket is empty, the ball bearings are located at the bottom of the first buoy 11. When the fish bucket is empty, the upper opening is inclined toward the moving pendulum. After entering the water, as the water level in the fish bucket gradually rises, the first buoy 11 begins to work, and the mouth of the fish bucket gradually becomes straight from the tilt. When it is close to being full of water, it becomes straight. The fish bucket continues to move downward, and under the action of the first buoy 11, the fish bucket is driven to rotate. After it is completely submerged in the water, the first buoy 11 of the moving pendulum rotates to the commanding height. This position is a balance point, and the angle between the mouth of the fish bucket and the horizontal plane is close to 90°. At this time, the weight 12 rolls to the first buoy The fish bucket is moved in front of the first buoy 11 and the fish bucket is lifted until the first buoy 11 is exposed to the water surface. Then, under the action of the weight 12, the moving pendulum rotates downward until the fish bucket is completely rotated above the water surface. The angle between the fish bucket mouth and the water surface is about 180°. The fish bucket is continued to be lifted upward. The first buoy 11 has a tendency to move away from the water surface and does not work. Under the action of the weight 12, the fish bucket rotates downward. After rotating through the lowest point, this position is also a balance point. The first buoy 11 or the moving pendulum starts to work, causing the fish bucket to continue to rotate to the starting state, and then rotates about 360°.

[0065] In a second specific embodiment, Figure 3 As shown, a rolling weight 12 is no longer used, but a fixed weight 12, i.e., a pendulum, is used. The pendulum itself has the same curvature as the inner wall of the tipping bucket 1, which facilitates the swing of the pendulum. When a fixed weight 12 is used, the weight 12 must be set in front of the first floating body 11 in the tipping direction of the tipping bucket 1, and a fixed weight 12 and a slide rail 13 are combined. The inner wall of the tipping bucket 1 is an arc-shaped inner wall, and the mobile pendulum also includes a slide rail 13 and a slider 14 used in conjunction. The weight 12 is a pendulum, and the first floating body 11 is fixed to the bottom of the pendulum. The bottom of the pendulum is provided with a slider 14, and the inner wall of the tipping bucket 1 is provided with a slide rail 13, and the two ends of the slide rail 13 are respectively provided with a first limit device 19 and a second limit device 20.

[0066] In a third specific embodiment, Figure 4 As shown, a rolling weight 12 is no longer used, but a fixed weight 12, i.e., a pendulum, is used. The pendulum itself has the same curvature as the inner wall of the tipping bucket 1, which facilitates the swing of the pendulum. When a fixed weight 12 is used, the weight 12 must be set in front of the first floating body 11 in the tipping direction of the tipping bucket 1, and a fixed weight 12 and a rotating shaft 17 are combined. The mobile pendulum also includes a rotating shaft 17 and a support rod 18. The weight 12 is a pendulum, and the rotating shaft 17 is rotatably set on the tipping bucket 1. One end of the support rod 18 is fixed on the rotating shaft 17, and the other end thereof is stuck between the first limit device 19 and the second limit device 20, as shown in FIG. Figure 6 As shown, the weight 12 and the first float 11 are fixed on the support rod 18 and are located at one end away from the rotating shaft 17. The weight 12 is arranged in front of the first float 11 in the flipping direction of the tipping bucket 1. In the present specific embodiment, that is, in the flipping direction of the tipping bucket 1, the first float 11 is closer to the rotating shaft 17 than the weight 12.

[0067] In a fourth specific embodiment, Figure 5 As shown, a mobile weight 12 and a rotating shaft 17 are combined. The mobile pendulum also includes a rotating shaft 17 and a support rod 18. A cavity is provided inside the first floating body 11, and the weight 12 is built in the cavity. The rotating shaft 17 is rotatably arranged on the tipping bucket 1, one end of the support rod 18 is fixed on the rotating shaft 17, and the first floating body 11 is fixed on the support rod 18 and is located at an end away from the rotating shaft 17. The first floating body 11 is provided with a third limit device 22 and is stuck between the first limit device 19 and the second limit device 20.

[0068] For the mobile pendulum being rotatably arranged along the inner wall of the tipping bucket 1 and having its rotation range limited by the limiting device, the embodiment of the present invention also provides a variety of specific implementation methods. In the above four embodiments, the first limiting device 19 and the second limiting device 20 are arranged at intervals on the inner wall of the same side of the tipping bucket 1, and the mobile pendulum is rotatably arranged along the inner wall of the tipping bucket 1 and is stuck between the first limiting device 19 and the second limiting device 20. Among them, for the third specific implementation method and the fourth specific implementation method, due to the existence of the rotating shaft 17, a method of limiting the rotating shaft 17 can be adopted, for example For example, the limiting device is a ratchet device, and a ratchet device is provided on the rotating shaft 17. The ratchet device is an existing device, which can limit the rotation range of the rotating shaft 17, thereby limiting the rotation range of the moving pendulum. Alternatively, a protrusion is provided on the rotating shaft 17, and the limiting device includes a first limiting device 19 and a second limiting device 20. The first limiting device 19 and the second limiting device 20 are provided on the tipping bucket 1 and surround the rotating shaft 17. The protrusion is stuck between the first limiting device 19 and the second limiting device 20, which can also limit the rotation range of the rotating shaft 17, thereby limiting the rotation range of the moving pendulum.

[0069] The present invention does not limit the rotation range of the mobile pendulum in the tipping bucket 1. Fig.14 As shown, Fig.14 The interval 1 in the figure is an interval when the mobile pendulum is rotated along the inner wall of the tipping bucket 1 and is stuck between the first limit device 19 and the second limit device 20. Of course, the first limit device 19 and the second limit device 20 can also be arranged at other positions on the inner wall of the same side of the tipping bucket 1 to form other intervals. It will not be repeated here. When the rotating shaft 17 is limited, it can also be limited in different intervals, such as Fig.14 As shown in interval 2, interval 3, interval 4 and interval 5.

[0070] In a fifth specific embodiment, Fig.15 As shown, the movable pendulum includes a first cross bar 24, a second cross bar 25 and a vertical bar 26, one end of the first cross bar 24 and the second cross bar 25 are connected to the tipping bucket 1, and the other end thereof is connected to the vertical bar 26, the limiting device includes a first limiting device 19 and a second limiting device 20, the first limiting device 19 and the second limiting device 20 are arranged on the vertical bar 26 at intervals, the first floating body 11 and the weighted object 12 are movably arranged on the vertical bar 26 and are located between the first limiting device 19 and the second limiting device 20. Of course, the first cross bar 24 can also be directly used as the first limiting device 19, and the second cross bar 25 can be used as the second limiting device 20.

[0071] Specifically, the first floating body 11 and the weighted object 12 are movably arranged on the vertical rod 26, or the first floating body 11 and the weighted object 12 are slidably arranged on the vertical rod 26, such as Fig.17 and Fig.18 As shown, the embodiment of the present invention does not specifically limit the positions of the first cross bar 24 and the second cross bar 25. Fig.17 As shown, the vertical rod 26 is tilted, and the second cross bar 25 is connected to the side wall of the tipping bucket 1. Of course, it can also be, as shown in FIG. Fig.18 As shown, the second cross bar 25 is connected to the bottom wall of the tipping bucket 1, or a cavity is provided inside the first floating body 11, and the weight 12 is built into the cavity, and the first floating body 11 is slidably arranged on the vertical bar 26, as shown in FIG. Fig.15 and Fig.16 As shown, similarly, the embodiment of the present invention does not specifically limit the positions of the first cross bar 24 and the second cross bar 25. Fig.15 As shown, the vertical rod 26 is tilted, and the second cross bar 25 is connected to the side wall of the tipping bucket 1. Of course, it can also be, as shown in FIG. Fig.16 As shown, the second cross bar 25 is connected to the bottom wall of the tipping bucket 1 .

[0072] For the mobile pendulum, the weighted object 12 and the first floating body 11 can be separated, or the weighted object 12 can move inside the cavity of the first floating body 11. The mobile pendulum has a rotation directionality. When rotating, the weighted object 12 is in front of the first floating body 11, and it can always rotate 360 ​​degrees when entering and exiting the water; on the contrary, the first floating body 11 rotates in front of the weighted object 12, and the mobile pendulum can only swing at a small angle, entering the floating tank to the top and exiting the water to the bottom.

[0073] The movable pendulum can be moved in the spherical shell of the fish bucket through a positioning slide rail, or it can be moved through a limit plate and a support rod passing through the center of the circle, that is, the rotating shaft 17. The purpose is to maximize the torque generated by gravity and buoyancy, so the weighted object 12 and the first floating body 11 rotate around the center of the circle, the center of the fish bucket as much as possible. However, there must be a rotation direction, and the weighted object 12 is in front of the first floating body 11 during rotation.

[0074] Moreover, the movable pendulum floats inside the fish bucket. Under the current circumstances, the fish bucket will lose water during transportation. When the amount of water in the fish bucket is lost to a certain extent, the center of gravity of the fish bucket remains unchanged on the vertical center of the hanging shaft during the floating of the movable pendulum from a high water level to a low water level, and the upper mouth of the fish bucket is always kept horizontal to prevent more water from being lost. If the internal structure of the fish bucket is a fixed eccentric structure, once water is lost, the fish bucket will tilt, and the tilt will become more and more serious. Therefore, the movable first float 11 and the weight 12 in the spherical shell of the fish bucket can move as the water level drops, and can balance a certain amount of water lost in the transportation of the spherical shell.

[0075] Moreover, the weight 12 and the first floating body 11 move in the spherical shell of the fish bucket, and after being filled with water, the spherical shell is straight and does not tilt, and the moving pendulum or the first floating body 11 can be balanced as long as it has a draft depth, and will not tilt. The turning is smoother, there is no water surface tension, and the lifting process is smoother.

[0076] In order to further optimize the above scheme, a crank arm 16 is provided on the outer wall of the tipping bucket 1. The crank arm 16 is an arc-shaped rod, or a straight rod, or a hinged rod, or a bending rod. The function of the crank arm 16 is to support other equipment to prevent the fish bucket from flipping after entering the water when used in conjunction with other equipment. If the tipping bucket 1 is used in conjunction with the lower cover body 3, a crank arm 16 is provided on the outer wall of the tipping bucket 1, and the tipping bucket 1 is rotatably arranged on the lower cover body 3, and the crank arm 16 is arranged on the outer side of the lower cover body 3. The arc-shaped crank arm of the arc-shaped rod requires small concentric rings, and the straight crank arm of the straight rod requires large concentric rings. The hinge crank arm of the hinged rod can have an arc and can be turned into a straight rod or a bending rod. The straight bent arm of the bending rod is simpler and has small concentric rings. The barrel-shaped upper cover body 2 and the lower cover body 3 of the fish bucket have a simple manufacturing process and small concentric rings.

[0077] For example, when used in conjunction with an existing fishing buoy, the automatic flipping device provided by the present invention is placed in the middle of the floating buoy, and the fish bucket and the floating buoy sink together. When the fish bucket is filled with water and needs to be flipped, the crank arm 16 is supported on the buoy, and the fish bucket will not flip. Since there is an extra-large fixed-depth buoy on the top of the floating buoy, the floating buoy and the fish bucket will stay at a certain water depth. When the fish bucket is lifted, the fish bucket and the floating buoy float together. The function of the crank arm 16 is to support the fish bucket on the floating buoy with its own weight, so that it can tilt and shake a small amount without flipping, which does not affect the function of the fish bucket. It does not affect the fish bucket's opening to always remain upward and basically horizontal when it moves up and down in the buoy.

[0078] Alternatively, the fish bucket may also be provided with a buoyancy box on the inner wall to reduce the gravity of the fish bucket in the water and the buoyancy required by the first float 11; or the fish bucket may adopt a double-layer structure, and only a partial buoyancy box may be provided in the rotation direction of the fish bucket. If the fish bucket is simply placed in the water and then turned over to empty the contents of the fish bucket, the arm does not need to be turned.

[0079] In order to further optimize the above scheme, the flip bucket 1 is a single-layer spherical shell, or a sandwich spherical shell with a cavity inside. The sandwich spherical shell can be hollow as a whole or partially hollow, thereby reducing the density of the fish bucket, reducing the buoyancy of the floating body required for the mobile pendulum to rotate, which is conducive to reducing the volume of the mobile pendulum in the fish bucket, increasing the water capacity of the fish bucket, reducing the size of the fish bucket, and reducing the manufacturing cost.

[0080] In order to further optimize the above solution, the above automatic turning device also includes an upper cover 2 buckled on the top of the turning bucket 1, such as Figure 7 As shown, the tipping bucket 1 is rotatably arranged relative to the upper cover body 2, and a light shield 5 is sleeved on the outer wall of the upper cover body 2. Fig. 9 It also includes a lower cover body 3, such as Figure 8 As shown, the upper cover body 2 and the lower cover body 3 are fixedly connected, the tipping bucket 1 is rotatably arranged on the lower cover body 3, the lower cover body 3 is provided with an elastic positioning pin 7, and the tipping bucket 1 is provided with a fixing hole 23 used in conjunction with the elastic positioning pin 7, as shown in FIG. Fig.13 As shown. Specifically, the elastic positioning pin 7 can be set at the bottom of the lower cover 3. The function of the bottom elastic positioning pin device is basically the same as the above-mentioned crank arm 16, and cooperates with other components to ensure that the fish bucket does not flip after entering the water. The bottom of the spherical shell of the fish bucket is provided with a limiting hole, and the lower cover 3 is provided with a limiting telescopic rod, that is, the elastic positioning pin 7, which is telescopically inserted into the limiting hole to complete the limiting. The elastic telescopic rod can adapt to the situation where the floating pontoon is separated from the fish bucket at a certain height, and the fish bucket always maintains a limited state.

[0081] The bottom of the upper cover 2 is provided with a plurality of through holes for fish to pass through, and the upper cover 2 may be a barrel-shaped body, or a barrel-shaped body at the bottom and a cone-shaped body or an arc-shaped body at the top. The present invention does not specifically limit the shape of the upper cover 2. The light shield 5 is provided with a plurality of through holes for fish to pass through, and both the upper cover 2 and the light shield 5 can play a certain role in preventing fish from jumping out. The light shield 5 may be a barrel-shaped body, or a barrel-shaped body at the bottom and a cone-shaped body or an arc-shaped body at the top. The present invention does not specifically limit the shape of the light shield 5.

[0082] The upper cover 2 and the lower cover 3 can both protect the automatic flipping device provided by the present invention. The upper cover 2 and the lower cover 3 can be welded. The lower cover 3 can be a barrel-shaped body at the upper part and a conical body or an arc-shaped body at the lower part. The inner wall surface of the lower part is an arc surface or a conical surface, which is convenient for the flipping bucket 1 to flip. The present invention does not specifically limit the shape of the lower cover 3. The conical body or arc-shaped body of the lower cover 3 is convenient for finding and positioning, and is conducive to placing it in an accurate position, such as in the middle hole of a floating pontoon.

[0083] In order to further optimize the above scheme, a buffer ring 6 surrounding the outer wall of the lower cover 3 is provided below the lower cover 3. The buffer ring 6 can be a conical elastic ring, which is equivalent to the buffer of the base. When used in conjunction with other equipment, it is installed at the position where the automatic flipping device provided by the present invention is to be placed, such as: the hole in the middle of the floating pontoon, the ground, and the bottom plate of the carriage of the transport vehicle, so as to reduce the shaking and collision of the automatic flipping device provided by the present invention with the surrounding matching objects in the space when it is not placed in a determined position; after being placed in place, it can also play an elastic blockage during the horizontal movement of the automatic flipping device provided by the present invention, reducing the impact of horizontal force.

[0084] In order to further optimize the above solution, a fish barrier 4 is provided in the cover of the tipping bucket 1. The fish barrier 4 includes a frame 8, fence leaves 9, a second buoy 21 and a third buoy 15. Fig.10 As shown, the frame 8 is fitted with the inner wall of the tipping bucket 1. Fig.11 As shown, the fence blades 9 are multiple and obliquely arranged in the frame 8, the second float 21 and the third float 15 are arranged on the fence blades 9 and are symmetrically arranged relative to the center line of the frame 8, and the fish barrier 4 is provided with avoidance holes 10 for the weighted object 12 to pass through. Specifically, the fish barrier 4 is a circular frame + oblique fence blades + left-right symmetrical floats. The oblique fence blades can play a role in oblique entry of fish and vertical blocking. The second float 21 and the third float 15 can keep the fence blades in a naturally horizontal state in the water and air. The avoidance hole 10 makes itself non-interfering with the moving pendulum and can swing between the first float 11 and the weighted object 12. The fish barrier 4 and the light shield 5 can both prevent fish from jumping out. The purpose of the fish barrier 4 and the light shield 5 is the same, and they are generally not used at the same time. To help understand, in Figure 1 The fish barrier 4 and the sunshade 5 appear at the same time.

[0085] The first float 11 , the second float 21 and the third float 15 may all be made of foam or other materials that can float in water.
