Technical Field

[0001] The utility model relates to the technical field of aquaculture equipment, in particular to a fishpond oxygenation device. Background Art

[0002] At present, breeders will install oxygenating machines in fishponds to supplement oxygen in the water of the fishponds through the machines, increasing the oxygen content. However, in the prior art, the oxygenation areas of relatively mature oxygenating machines are fixed. Vertically, only one water area among the upper, middle or lower layers can be oxygenated, and horizontally, only the water area around the oxygenating machine can be oxygenated. The oxygenation range is too small and the oxygenation effect is not good.

[0003] Therefore, the patent with the application number CN201711253087.3 discloses a fishpond oxygenating machine. By controlling the depth of the water pump through a motor, the water at different depths in the fishpond is injected into a sprayer to realize oxygenation of the water at different depths in the vertical plane. The whole device is fixed in the hull by a bottom plate, which is convenient for moving in the fishpond to realize oxygenation of the water in different water areas in the horizontal plane. Although this patent solves the problem of limited oxygenation water area of the existing oxygenating machine, since its L-shaped bracket is fixed, when the hull moves to the target water area for oxygenation, it is necessary to turn and move the hull to oxygenate the surrounding water areas, and it is not convenient to use. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a fishpond oxygenation device, which can oxygenate the surrounding water areas without turning and moving the hull.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A fishpond oxygenation device includes an L-shaped bracket, a winch, a water pump, a fixed pulley, a telescopic member and an angle adjustment mechanism; the winch is rotatably connected to the vertical side of the L-shaped bracket; the water pump is arranged on the horizontal side of the L-shaped bracket and is communicated with a sprayer through a water pipe, and the sprayer is installed at the end of the horizontal side of the L-shaped bracket; the fixed pulley is rotatably connected to the L-shaped bracket between the winch and the water pump, and the lifting rope of the winch bypasses the fixed pulley to suspend the water pump, and rotating the winch can drive the water pump to move up and down through the lifting rope;

[0007] The telescopic member is arranged along the horizontal side of the L-shaped bracket, the movable end of the telescopic member is connected to the fixed pulley, and the telescopic member can drive the fixed pulley to move horizontally along the horizontal side of the L-shaped bracket; the angle adjustment mechanism is arranged at the lower end of the vertical side of the L-shaped bracket, and the angle adjustment mechanism can drive the L-shaped bracket to rotate with its vertical side as the central axis.

[0008] As an alternative solution, the angle adjustment mechanism includes a housing and a first motor, a driving gear, and a driven gear located inside the housing; the output shaft of the first motor is coaxially connected to the driving gear, and the driving gear is drivingly connected to the driven gear; the vertical side of the L-shaped bracket penetrates through the housing and is coaxially connected to the driven gear.

[0009] As an alternative solution, the diameter of the driving gear is smaller than the diameter of the driven gear.

[0010] As an alternative solution, the fish pond aeration device further includes a second motor, the output shaft of the second motor is coaxially connected to the reel, an opening exposing the driven gear is provided on the top wall of the housing, and the second motor is installed on the upper surface of the driven gear through the opening.

[0011] As an alternative solution, a sliding groove is formed in the transverse edge of the L-shaped bracket along the length direction, a slider is slidably connected in the sliding groove, a fixed pulley is rotatably connected to one side of the slider, and the movable end of the telescopic member is fixedly connected to the other side of the slider, and the fixed end of the telescopic member is fixedly connected to the transverse edge of the L-shaped bracket.

[0012] As an alternative solution, the telescopic member is a multi-section telescopic cylinder or a multi-section electric push rod.

[0013] As an alternative solution, two fixed pulleys are provided, one fixed pulley is rotatably connected to the transverse edge of the L-shaped bracket, and the other fixed pulley is rotatably connected to the corner of the L-shaped bracket.

[0014] Due to the adoption of the above technical solutions, the present utility model will have the following beneficial effects:

[0015] 1. The fish pond aeration device provided by the present utility model adopts a telescopic member arranged along the transverse edge of the L-shaped bracket. Since the movable end of the telescopic member is connected to the fixed pulley, the telescopic member can drive the fixed pulley to move horizontally along the transverse edge of the L-shaped bracket. Therefore, the telescopic member can horizontally move the water pump along the transverse edge of the L-shaped bracket; at the same time, an angle adjustment mechanism is provided at the lower end of the vertical side of the L-shaped bracket. Since the angle adjustment mechanism can drive the L-shaped bracket to rotate with its vertical side as the central axis, the water pump can make a circular motion with the vertical side of the L-shaped bracket as the center; in this way, through the horizontal movement and circular motion of the water pump, the horizontal position of the water pump can be adjusted. When the hull moves to the target water area for aeration, it is not necessary to turn and move the hull to aerate the surrounding water area, which is convenient to use.

[0016] 2. The fishpond aeration equipment provided by the utility model can change the direction of force by setting a fixed pulley, and the pulling force on the water pump is applied by a reel. The reaction force received by the reel when applying the pulling force can be transmitted to the hull through an L-shaped bracket. Therefore, by setting the reel on the vertical side of the L-shaped bracket, compared with setting it on the horizontal side, the reel is closer to the hull, which can prevent the L-shaped bracket from bending.

[0027] Please refer to Figures 1-5 , in an embodiment of an oxygenation device for fish ponds of the present utility model, the oxygenation device for fish ponds includes an L-shaped bracket 1, a winch 2, a water pump 3, a fixed pulley 4, a telescopic member 5, and an angle adjustment mechanism 6;

[0028] Among them, the lower end of the vertical side of the L-shaped bracket 1 is used for installation on the hull. The winch 2 is rotatably connected to the vertical side of the L-shaped bracket 1. The winch 2 belongs to the prior art and is commonly used in lifting equipment. A lifting rope 21 is wound around the winch 2. The water pump 3 is arranged on the horizontal side of the L-shaped bracket 1 and is connected to a sprayer 31 through a water pipe (not shown in the figure). The sprayer 31 is installed at the end of the horizontal side of the L-shaped bracket 1. After the water pumped by the water pump 3 is injected into the sprayer 31, it is sprayed out from the sprayer 31, which can increase the dissolved oxygen rate of the pumped water. The fixed pulley 4 is rotatably connected to the L-shaped bracket 1 between the winch 2 and the water pump 3. The lifting rope 21 of the winch 2 bypasses the fixed pulley 4 to suspend and connect the water pump 3. By rotating the winch 2, the water pump 3 can be driven to move up and down through the lifting rope 21 to pump water at different depths, so as to oxygenate the water at different depths on the vertical plane.

[0029] Among them, the telescopic member 5 is arranged along the horizontal side of the L-shaped bracket 1. The movable end of the telescopic member 5 is connected to the fixed pulley 4. The telescopic member 5 can drive the fixed pulley 4 to move horizontally along the horizontal side of the L-shaped bracket 1; the angle adjustment mechanism 6 is arranged at the lower end of the vertical side of the L-shaped bracket 1. The angle adjustment mechanism 6 can drive the L-shaped bracket 1 to rotate with its vertical side as the central axis.

[0030] Specifically, the angle adjustment mechanism 6 includes a housing 64 and a first motor 61, a driving gear 62, and a driven gear 63 located inside the housing 64. The output shaft of the first motor 61 is coaxially connected to the driving gear 62 through a coupling. The driving gear 62 is connected to the driven gear 63 through gear transmission. A pedestal bearing 631 is connected to the lower surface of the driven gear 63 through a connecting shaft, and the pedestal bearing 631 is installed on the inner bottom wall of the housing 64. The vertical side of the L-shaped bracket 1 passes through the housing 64 and is coaxially connected to the driven gear 63. When in use, the first motor 61 drives the driving gear 62 to rotate, and the driving gear 62 drives the L-shaped bracket 1 to rotate around its vertical side as the central axis through the driven gear 63.

[0031] More specifically, the diameter of the driving gear 62 can be set to be smaller than that of the driven gear 63, so that the number of teeth of the driving gear 62 is less than that of the driven gear 63, to increase the rotational speed of the L-shaped bracket 1, thereby increasing the output torque of the L-shaped bracket 1. The input of the first motor 61 with high speed and low torque is converted into the output of the L-shaped bracket 1 with low speed and high torque, which is easier to overcome the resistance when the L-shaped bracket 1 rotates the water pump 3, and can improve the adjustment accuracy of the first motor 61.

[0032] Specifically, it can also be set that the fish pond aeration device includes a second motor 7. The output shaft of the second motor 7 is coaxially connected to the reel 2 through a coupling. A circular opening exposing the driven gear 63 is provided on the top wall of the housing 64, and the second motor 7 is installed on the upper surface of the driven gear 63 through this opening. When in use, the second motor 7 drives the reel 2 to rotate, which is more convenient and labor-saving.

[0033] It should be noted that the above first motor 61 and second motor 7 can adopt a stepper motor or a servo motor to improve the position control accuracy of the water pump 3.

[0034] Specifically, a chute 11 extending along the length direction of the horizontal side of the L-shaped bracket 1 is formed through the horizontal side of the L-shaped bracket 1. A slider 12 is slidably connected in the chute 11. One side of the slider 12 is rotatably connected to a fixed pulley 4, and the other side of the slider 12 is fixedly connected to the movable end of a telescopic member 5. The fixed end of the telescopic member 5 is fixedly connected to the horizontal side of the L-shaped bracket 1. When in use, the telescopic member 5 drives the slider 12 to slide back and forth along the chute 11 through elongation and shortening, so as to horizontally move the water pump 3 along the horizontal side of the L-shaped bracket 1.

[0035] More specifically, the telescopic member 5 can be set as a multi-stage telescopic cylinder or a multi-stage electric push rod to increase the maximum stroke of the telescopic member 5, thereby expanding the water area where oxygen can be increased. The multi-stage telescopic cylinder is a specially designed pneumatic or hydraulic device used to provide linear motion with a long stroke while maintaining a short contracted length. Its design is similar to a telescope and consists of multiple parts, each of which can be extended when needed to achieve a longer total stroke. The multi-stage electric push rod also adopts the prior art with a similar design as described above.

[0036] Specifically, the number of fixed pulleys 4 can be set to two. One fixed pulley 4 is rotatably connected to the horizontal side of the L-shaped bracket 1, and the other fixed pulley 4 is rotatably connected to the corner of the L-shaped bracket 1. The pulling direction of the water pump 3 can be changed to the vertical direction, thereby reducing the lateral force received by the L-shaped bracket 1 and preventing the L-shaped bracket 1 from tipping over.

[0037] The usage method or working principle of the present utility model is as follows:

[0038] Install the housing 64 on the hull and move to the target water area with the hull. Drive the reel 2 to rotate through the second motor 7. The rotation of the reel 2 drives the water pump 3 to move up and down through the lifting rope 21 to pump water at different depths. After the water pumped by the water pump 3 is injected into the sprayer 31, it is sprayed out from the sprayer 31, which can increase the dissolved oxygen rate of the pumped water and achieve oxygenation of the water at different depths on the vertical plane.

[0039] When it is necessary to oxygenate the surrounding water area, drive the driving gear 62 to rotate through the first motor 61. The rotation of the driving gear 62 drives the L-shaped bracket 1 to rotate around its vertical side as the central axis through the driven gear 63, so that the water pump 3 makes a circular motion with the vertical side of the L-shaped bracket 1 as the center; drive the slider 12 to slide back and forth along the chute 11 through the extension and shortening of the telescopic member 5, so as to horizontally move the water pump 3 along the horizontal side of the L-shaped bracket 1; in this way, through the horizontal movement and circular motion of the water pump 3, the horizontal position of the water pump 3 can be adjusted. When the hull moves to the target water area for oxygenation, it is not necessary to turn and move the hull to oxygenate the surrounding water area.

[0040] In addition, since the fixed pulley 4 can change the direction of the force, and the pulling force on the water pump 3 is applied by the reel 2, the reaction force received by the reel 2 when applying the pulling force can be transmitted to the hull through the L-shaped bracket 1. Therefore, when the reel 2 is arranged on the vertical side of the L-shaped bracket 1, compared with being arranged on the horizontal side, the reel 2 is closer to the hull, which can prevent the L-shaped bracket 1 from bending.

[0041] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
