Description

Technical Field

[0001] The invention relates to the technical field of fish pond oxygenation, and in particular to a photovoltaic fish pond oxygenation device. Background Art

[0002] Photovoltaic fish pond is a method of raising fish using the complementary approach of fishery and photovoltaic power generation. Fishery and photovoltaic complementarity refers to the combination of fishery farming and photovoltaic power generation. A photovoltaic panel array is set up above the surface of the fish pond, and fish and shrimp can be farmed in the water below the photovoltaic panels. The photovoltaic array can also provide good shielding for fish farming, forming a new power generation model of "generating electricity above and raising fish below".

[0003] In fish farming, oxygen is one of the necessary conditions for fish survival and growth. The oxygen content in fish pond water is mainly related to factors such as natural temperature, humidity and fish density. Fish are extremely sensitive to the oxygen content in water. When the oxygen content in water is low, fish will float, flood the pond, and die on a large scale. At this time, the fish pond needs to be oxygenated. However, most of the existing fish pond oxygenation equipment is in a fixed position and cannot be moved flexibly. In order to achieve effective coverage of the fish pond and ensure the oxygenation effect, it is often necessary to arrange multiple aerators in the fish pond, which will increase the equipment cost.

[0004] Chinese patent CN105475220B discloses a mobile pond oxygenation device. The application provides an oxygenation device on the hull to achieve all-round oxygenation of the fish pond through the movement of the hull. However, if the application is used in photovoltaic fish ponds, due to the presence of a large number of photovoltaic columns in the photovoltaic fish pond, when the hull moves, if strong winds occur, the hull and the photovoltaic columns will collide, which will cause damage to the hull and affect the service life of the hull. Summary of the invention

[0005] In view of the above problems, a photovoltaic fish pond oxygenation device is provided. By arranging an oxygenation device on the hull, all-round oxygenation of the fish pond is achieved, and anti-collision devices are respectively provided on both sides of the hull. The anti-collision devices can avoid damage to the hull caused by collision between the hull and the photovoltaic column when encountering strong winds. In addition, a reverse thrust device is provided at the forward end of the hull. When the hull collides with the photovoltaic column and cannot turn forward, the reverse thrust device can achieve contact with the photovoltaic column and push the hull, thereby helping the hull to turn, realizing the normal movement route of the hull, and ensuring all-round oxygenation of the fish pond.

DETAILED DESCRIPTION

[0038] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] See also Figures 1 to 12As shown, a photovoltaic fish pond oxygenation device comprises a movable hull 1, on which a pair of oxygenation devices 2 for oxygenating the fish pond are arranged, and on both sides of the hull 1 are symmetrically provided with anti-collision devices 3 for protecting both sides of the hull 1, the anti-collision devices 3 comprise an anti-collision plate 31 in a vertical state, and both ends of the anti-collision plate 31 are respectively connected to the side of the hull 1 through a shock absorbing mechanism 32, and two shock absorbing mechanisms 32 are symmetrically arranged at both ends of the anti-collision plate 31, and the side of the anti-collision plate 31 close to the hull 1 is connected to the side of the hull 1 through a plurality of equidistantly distributed shock absorbing rebound mechanisms 33; the side of the hull 1 close to the forward end is provided with a slide groove 11 perpendicular to the forward direction of the hull 1, and a reverse thrust device 4 is arranged in the slide groove 11.

[0040] When it is necessary to perform oxygenation operation on the photovoltaic fish pond, since the area of ​​the photovoltaic fish pond is generally large, the fixed oxygenation mode can only oxygenate a fixed range of the fish pond, so a movable hull 1 is provided, and oxygenation devices 2 are respectively provided on both sides of the hull 1. The two oxygenation devices 2 can perform all-round oxygenation on the photovoltaic fish pond through the movement of the hull 1. However, during the movement of the hull 1, due to the presence of a large number of photovoltaic columns in the photovoltaic fish pond, if the hull 1 encounters strong winds during the movement, the hull 1 may be out of control due to the strong wind, so that the side of the hull 1 is prone to collide with the photovoltaic columns. Therefore, a pair of anti-collision devices 3 are respectively provided on both sides of the hull 1. The anti-collision device 3 can protect the hull 1 in the event of a collision, wherein the anti-collision device 3 includes a horizontal anti-collision plate 31, The two sides of the anti-collision plate 31 are connected to the hull 1 through a shock-absorbing mechanism 32 respectively. The shock-absorbing mechanism 32 can absorb the impact force from the photovoltaic column. At the same time, the anti-collision plate 31 is connected to the side close to the hull 1 with multiple shock-absorbing and rebound components. The shock-absorbing and rebound components can absorb part of the impact force and rebound at the same time, so that the hull 1 can be quickly separated from the photovoltaic column; when the hull 1 collides, continuous strong winds may cause the side of the hull 1 to always keep in contact with the photovoltaic column, resulting in the inability to turn the bow, making it difficult to achieve the forward movement of the hull 1, so that a reverse thrust device 4 is provided on the hull 1, so that when the bow cannot turn, the reverse thrust device 4 can contact the photovoltaic column, and the bow is turned by the reverse thrust, thereby ensuring the movement of the hull 1 in the photovoltaic fish pond.

[0041] See also Figures 4 to 6 As shown, the shock absorbing mechanism 32 includes a connecting plate 321 which is hinged to one end of the anti-collision plate 31 and is in a vertical shape. The upper and lower surfaces of the connecting plate 321 away from one end of the anti-collision plate 31 are respectively provided with sliding components 322. The sliding component 322 includes a hinge block 3221 rotatably connected to the connecting plate 321. A first sliding block 3222 is provided on the side of the hinge block 3221 close to the hull 1. The first sliding block 3222 is connected to the hull 1 through a sliding bar 3223.

[0042] When the anti-collision plate 31 collides with the photovoltaic column, the anti-collision plate 31 will move toward the direction of the hull 1. When the impact force needs to be released, connecting plates 321 are hinged at both ends of the anti-collision plate 31. The connection between the connecting plate 321 and the anti-collision plate 31 is at a certain angle. When a collision occurs, the anti-collision plate 31 will move toward the hull 1, thereby causing the angle between the anti-collision plate 31 and the connecting plate 321 to become larger. The increase in the angle will make the total length of the anti-collision plate 31 and the connecting plate 321 longer. Therefore, a pair of sliding components 322 are provided at one end of the connecting plate 321 away from the anti-collision plate 31, and the connecting plate 321 is connected to the hull 1 through the sliding component 322. Therefore, the friction force when the sliding component 322 slides can unload the impact force from the photovoltaic column, thereby reducing part of the impact force from the photovoltaic column.

[0043] See also Figure 4 and Figure 5 As shown, a shock absorbing assembly 323 is respectively provided on one side of the two slide bars 3223 close to the anti-collision plate 31, and the two shock absorbing assemblies 323 are symmetrically arranged up and down, and the shock absorbing assembly 323 includes a slide bar 3231, a second slider 3233, a first spring 3234, a first hinge seat 3235, a second hinge seat 3236 and a connecting rod 3237; the slide bar 3231 is horizontal and its two ends are respectively installed on the side of the hull 1 through fixing blocks 3232, and the slide bar 3231 is located on the side of the slide bar 3223 close to the anti-collision plate 31; the second slide The block 3233 is slidably arranged on the slide rod 3231; the first spring 3234 is sleeved on the slide rod 3231 and is located on the side of the second slider 3233 close to the slide bar 3223, and the two ends of the first spring 3234 are respectively abutted against the second slider 3233 and the fixed block 3232; the first hinge column is installed on the side of the second slider 3233 away from the hull 1; the second hinge column is installed on the side of the anti-collision plate 31 close to the hull 1; the connecting rod 3237 is horizontal and its two ends are respectively connected to the first hinge column and the second hinge column.

[0044] When it is necessary to reduce the impact force caused by the anti-collision plate 31 on the hull 1, shock-absorbing mechanisms 32 are respectively provided at both ends of the anti-collision plate 31, and the two shock-absorbing mechanisms 32 are respectively provided with a pair of shock-absorbing components 323, and the four shock-absorbing components 323 are respectively installed at the four corners of the anti-collision plate 31. When the anti-collision plate 31 collides, the anti-collision plate 31 will move toward the direction of the hull 1, and the movement of the anti-collision plate 31 causes the connecting rod 3237 to rotate slightly around the second hinge seat 3236 as the axis, thereby causing the first hinge seat 3235 to move toward the end away from the anti-collision plate 31, and the movement of the movable hinge seat causes the second slider 3233 to move on the slide rod 3231. Therefore, by providing a first spring 3234 on the slide rod 3231, the movement of the second slider 3233 can squeeze the first spring 3234, thereby achieving the force unloading effect on the second slider 3233, and thus the impact force from the anti-collision plate 31 can be reduced by the first spring 3234.

[0045] See also Figure 6 As shown, the shock-absorbing rebound mechanism 33 includes a base 331, a shock-absorbing column 333 and a second spring 334; the base 331 is horizontally installed on the side of the hull 1 close to the anti-collision plate 31, and the interior of the base 331 has a slidable shock-absorbing piston 332; the shock-absorbing column 333 is horizontal and one end of it is connected to the shock-absorbing piston 332, and the end of the shock-absorbing column 333 away from the shock-absorbing piston 332 is connected to the anti-collision plate 31.

[0046] When the hull 1 loses control and causes the anti-collision plate 31 on the side of the hull 1 to collide with the photovoltaic column, in order to avoid damage to the hull 1 caused by continuous collision, a plurality of shock-absorbing and rebound mechanisms 33 for shock-absorbing and rebound are provided between the anti-collision plate 31 and the hull 1. After the collision, the anti-collision plate 31 will move to the side of the hull 1. The movement of the anti-collision plate 31 causes the shock-absorbing column 333 to drive the shock-absorbing piston 332 to move in the base 331, and the impact force can be released by the shock-absorbing piston 332. In addition, a second spring 334 is provided between the shock-absorbing column 333 and the anti-collision plate 31. The second spring 334 can release part of the impact force while applying part of the thrust to the anti-collision plate 31, so that the hull 1 can be quickly separated from the photovoltaic column, thereby avoiding damage caused by continuous collision of the hull 1.

[0047] See also Figures 7 to 12As shown, the reverse thrust device 4 includes a moving frame 41, a rotating disk 42, a first motor 43, a fixed arm 44 and a pushing mechanism 48; the moving frame 41 is installed in the slide slot 11 and can move in the slide slot 11 through a horizontal moving mechanism 46; the rotating disk 42 is horizontally and rotatably installed on the top surface of the moving frame 41; the first motor 43 is vertically installed on the moving frame 41, and the output end of the first motor 43 is coaxially connected with the rotating disk 42; the fixed arm 44 is horizontally installed on the top surface of the rotating disk 42, and a telescopic arm 45 that can slide with the fixed arm 44 is provided inside the fixed arm 44, and the telescopic arm 45 is telescopically extended by a telescopic driving mechanism 47; the pushing mechanism 48 is installed at one end of the telescopic arm 45 away from the fixed arm 44.

[0048] When the hull 1 contacts the photovoltaic column due to continuous strong winds, the hull 1 cannot be turned due to the influence of the strong winds, thus affecting the moving route of the hull 1. By providing a reverse thrust device 4 on the front side of the hull 1, the reverse thrust device 4 can contact the photovoltaic column when working, and the hull 1 can be separated from the photovoltaic column by thrust. By providing a moving frame 41 in the slide 11, the moving frame 41 can move along the slide 11 through a horizontal moving mechanism 46, and by providing a rotating disk 42 on the top surface of the moving frame 41, the rotating disk 42 can move through the first A motor 43 is used to rotate. When it is necessary to escape, the mobile frame 41 can be moved according to the position of the photovoltaic column, and the first motor 43 drives the rotation of the rotating disk 42 to align the pushing mechanism 48 with the photovoltaic column. The telescopic drive mechanism 47 can also drive the telescopic arm 45, so that the pushing mechanism 48 can contact the photovoltaic column, and the continuous thrust can separate the photovoltaic column from the hull 1, thereby avoiding the problem of the hull 1 being unable to turn after colliding with the photovoltaic column due to strong winds.

[0049] See also Fig.11 and Fig.12 As shown, the pushing mechanism 48 includes a U-shaped block 481 and a buffer assembly 485; the U-shaped block 481 is horizontally installed at one end of the telescopic arm 45 away from the fixed arm 44; a horizontal arc-shaped push rod 482 is provided in the middle of the U-shaped block 481; both ends of the arc-shaped push rod 482 are respectively connected to vertical fixing rods 483; both ends of the fixing rod 483 are respectively installed on the U-shaped block 481 through fixing plates 484, and the fixing rod 483 and the fixing plate 484 can cooperate and slide; the buffer assembly 485 is installed on the U-shaped block 481 and is connected to the arc-shaped push rod 482.

[0050] When the telescopic arm 45 moves, the pushing mechanism 48 can come into contact with the photovoltaic column, so that the hull 1 and the photovoltaic column can be separated during the pushing process. A U-shaped block 481 is provided at the end of the telescopic arm 45 away from the fixed arm 44, and an arc-shaped push rod 482 is provided in the U-shaped block 481, which matches the surface of the photovoltaic column, and the two ends of the sliding push rod can be slidably installed on the U-shaped block 481. A buffer component 485 connected to the U-shaped block 481 is provided on the side of the arc-shaped push rod 482 close to the U-shaped block 481. The buffer component 485 can avoid excessive thrust at the moment when the arc-shaped push rod 482 contacts the photovoltaic column, which may cause damage to the telescopic arm 45.

[0051] See also Fig.11 and Fig.12 As shown, the buffer assembly 485 includes a buffer column 4851 and a third spring 4853; the buffer column 4851 is horizontally and slidably arranged on the U-shaped block 481, one end of the buffer column 4851 is connected to the arc push rod 482, and a limit block 4852 is provided at the end of the buffer column 4851 away from the arc push rod 482, and the limit block 4852 is located on the side of the U-shaped block 481 away from the arc push rod 482; the third spring 4853 is sleeved on the buffer column 4851, one end of the third spring 4853 is abutted against the arc push rod 482, and the end of the third spring 4853 away from the arc push rod 482 is abutted against the U-shaped block 481.

[0052] When it is necessary to increase the buffer of the arc push rod 482, first, the two ends of the arc push rod 482 are slidably set on the U-shaped block 481, and then a buffer column 4851 is provided on the side of the arc push rod 482 close to the U-shaped block 481, the buffer column 4851 can slide on the U-shaped block 481, and a limit block 4852 is provided on the side of the U-shaped block 481 away from the arc push rod 482, the limit block 4852 is connected to the buffer column 4851, and a third spring 4853 is provided on the buffer column 4851. When the arc push rod 482 contacts the photovoltaic column and causes the arc push rod 482 to move toward one side of the U-shaped block 481, the movement of the arc push rod 482 causes the third spring 4853 to be squeezed, thereby reducing the instantaneous thrust on the U-shaped block 481 and avoiding damage to the telescopic arm 45 caused by the instantaneous thrust.

[0053] See also Figure 7As shown, the horizontal moving mechanism 46 includes a screw rod 461, a first rotating wheel 462 and a second motor 464; the screw rod 461 is horizontally and rotatably installed in the slide groove 11, and the screw rod 461 is rotatably connected to the moving frame 41; the first rotating wheel 462 is vertically installed at one end of the screw rod 461; the second motor 464 is installed on the hull 1 through a motor bracket 463, and the output end of the second motor 464 is provided with a vertical second rotating wheel 465, and the second rotating wheel 465 is connected to the first rotating wheel 462 through a synchronous belt 466.

[0054] When it is necessary to drive the movable frame 41 to move horizontally, a horizontal screw 461 is provided in the slide groove 11, and the screw 461 is rotatably connected to the movable frame 41. Therefore, when the second motor 464 is started, the rotation of the second motor 464 can rotate the second wheel 465. The rotation of the second wheel 465 causes the synchronous belt 466 to drive the first wheel 462 to rotate.
