Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a water flow disturbance device for aquaculture. Background Art

[0002] The hatching of fertilized shrimp eggs has always been an important part of shrimp seedling cultivation. The hatching rate directly determines the production cost and final profit of seedling cultivation. During the hatching process of fertilized shrimp eggs, the water in the hatching pool needs to be stirred continuously to prevent the fertilized eggs from stacking and the water from getting moldy, which may lead to the death and deterioration of the fertilized eggs.

[0003] Under current conditions, operators generally use tools to stir the eggs once an hour, which results in high labor costs, difficulty in supervision, dead corners for stirring, and damage to the fertilized eggs if operators operate improperly.

[0004] The automatic stirring equipment currently on the market uses a motor to drive the screen plate to move horizontally at a uniform speed in the pool. Under the action of gravity, shrimp eggs will spontaneously settle to the bottom of the hatchery pool, causing vertical stratification of oxygen content. Horizontal stirring can only create horizontal water flow, which is unable to lift the shrimp eggs on the bottom layer and promote the descent of oxygen-rich water on the top layer. Therefore, additional aeration structures are often required for oxygen supplementation, and the structure is more complicated, which adds to the breeding cost.

[0005] In addition, when the sieve plate in the above-mentioned automatic stirring device moves at a constant speed in the pool, the regular water flow generated is easily offset by the water flow rebounding from the pool wall, which greatly reduces the disturbance effect of the device on the water flow.

[0030] Below, in conjunction with specific implementation methods, the utility model is further described:

[0031] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] like Figure 1-5 A water flow disturbance device for aquaculture shown in the figure includes a pool body 1, a bracket 4, an agitator and a driving assembly. The pool body 1 has a first pool wall 2 and a second pool wall 3. The first pool wall 2 and the second pool wall 3 are arranged opposite to each other. One end of the bracket 4 is connected to the first pool wall 2, and the other end of the bracket 4 extends to the second pool wall 3 along the extension direction of the pool body 1 and is connected thereto, and then the agitator is installed in the pool body 1; in addition, the driving assembly includes a driving member 5 and a transmission member, and the power output end of the driving member 5 is connected to the transmission member, and the transmission member is connected to the agitator, so that the transmission member is driven to rotate through the driving member 5, and the transmission member is used to drive the agitator to move up and down along the height direction of the pool body 1 when rotating.

[0034] On the basis of the above structure, during assembly, one end of the bracket 4 is installed on the first pool wall 2, and the other end of the bracket 4 extends along the extension direction of the pool body 1 to the second pool wall 3 and is connected thereto, so that the bracket 4 can span across the top of the pool body 1, and the driving member 5 can be installed on one side of the first pool wall 2 or the second pool wall 3, and the transmission member can be connected to the driving member 5 through a conveyor belt 11 or a chain, etc. During assembly, the transmission member can be installed on the bracket 4 and located above the pool body 1, and then connected to the end of the stirring member away from the pool body 1 through a connecting rod 42 or a rope or other connecting member, so that when the transmission member rotates, it can drive the stirring member to move up and down along the height direction of the pool body 1, and the stirring member can stir the water flow in the pool body 1 up and down during the process of moving up and down along the height direction of the pool body 1.

[0035] It should be noted that the automatic stirring equipment currently on the market uses a motor to drive the screen plate to move horizontally at a uniform speed in the pool. Under the action of gravity, shrimp eggs will spontaneously settle to the bottom of the hatchery pool, causing vertical stratification of oxygen content. Horizontal stirring can only create horizontal water flow, which is unable to lift the shrimp eggs on the bottom layer and promote the descent of oxygen-rich water on the top layer. Therefore, additional aeration structures are often required for oxygen supplementation, and the structure is more complicated, which adds to the breeding cost.

[0036] Therefore, when using the water flow disturbance device for aquaculture in the utility model, a stirring member is arranged in the pool body 1, the transmission member is connected to the stirring member, and the transmission member is driven to rotate by the driving member 5, so that the stirring member can move up and down along the height direction of the pool body 1 during the rotation of the transmission member, thereby creating a continuously changing water flow. Compared with allowing the stirring member to move horizontally at a uniform speed in the pool, the stirring member disturbing the water flow up and down helps to break the water body stratification phenomenon, so that the oxygen, nutrients, etc. in the water body are evenly distributed, providing a more stable and suitable growth environment for the cultured organisms, thereby promoting the uniform distribution of the oxygen content in the water body and the fertilized shrimp eggs in space, without the need to add an additional aeration structure, and effectively reducing labor costs;

[0037] In addition, stirring the water flow up and down by the stirring element can more effectively promote the oxygen exchange of the water body. This stirring method can stir the oxygen-rich water layer at the bottom of the water body upward, thereby increasing the overall oxygen concentration of the water body. In comparison, although lateral disturbance of water flow can also promote oxygen exchange, its effect may not be as direct and efficient as up and down stirring, so the stirring effect is better.

[0038] It should be noted that the drive member 5 can be an existing drive motor, and the transmission member can be a gear, pulley or roller mechanism. When the two are assembled, they can be connected through a rack, chain or conveyor belt 11.

[0039] Furthermore, the above-mentioned bracket 4 includes at least two support rods 41 and at least one connecting rod 42. The two support rods 41 are respectively installed on the first pool wall 2 and the second pool wall 3. One end of the connecting rod 42 is connected to one of the support rods 41, and the other end of the connecting rod 42 extends to the top of the second pool wall 3 and is connected to the other support rod 41.

[0040] Specifically, during assembly, the two support rods 41 can be installed on the first pool wall 2 and the second pool wall 3 respectively, and then the two ends of the connecting rod 42 are respectively connected to the top ends of the two support rods 41, so that the connecting rod 42 spans above the pool body 1 through the two support rods 41, and the transmission member is installed through the connecting rod 42, so that the transmission member can be located above the pool body 1 and connected to the agitator, so that the agitator can have space to move up and down in the height direction of the pool body 1.

[0041] It should be noted that the connecting rod 42 can be connected to the two support rods 41 by welding or clamping or through connecting parts (such as screws or bolts, etc.), and the two support rods 41 can be connected to the pool body 1 by plug-in or welding, and the specific assembly can be based on actual needs.

[0042] Furthermore, the transmission member includes a transmission wheel, a driven wheel 7 and a conveyor belt 11, which connects the transmission wheel to the driving member 5. The driven wheel 7 is rotatably installed on the connecting rod 42. The two ends of the conveyor belt 11 are respectively connected to the transmission wheel and the driven wheel 7. The driving member 5 is used to drive the transmission wheel to rotate, and the driven wheel 7 can rotate when the transmission wheel rotates, and is used to drive the agitator to move up and down along the height direction of the pool body 1 when rotating.

[0043] Specifically, the transmission member in this embodiment specifically includes a transmission wheel, a driven wheel 7 and a conveyor belt 11. During assembly, in order to facilitate the user to operate the driving member 5, the driving member 5 can be installed on the first pool wall 2 or the second pool wall 3, and then the transmission wheel is connected to the power output end of the driving member 5, and the driven wheel 7 is connected to the transmission wheel through the conveyor belt 11. In this way, when the driving member 5 is turned on, the transmission wheel can be driven to rotate, and under the action of the conveyor belt 11, the driven wheel 7 also rotates synchronously. At this time, the agitator connected to the driven wheel 7 can move up and down according to the height of the pool body 1 to create a water flow disturbance phenomenon.

[0044] Preferably, in this embodiment, the driving wheel and the driven wheel 7 can be rollers or pulleys, and the transmission belt can be a toothed synchronous belt or a transmission belt. Of course, the driving wheel and the driven wheel 7 can also be gears. In this case, the conveyor belt 11 can be formed by connection or rack.

[0045] Furthermore, the driving member 5 includes a driving motor and a motor output shaft. During assembly, a turntable 10 can be provided on the motor output shaft. At this time, the turntable 10 is formed as a transmission wheel, and then the turntable 10 is connected to the driven wheel 7 through a conveyor belt 11, so that when the driving motor drives the motor output shaft to rotate, the turntable 10 can rotate synchronously to drive the driven wheel 7 to rotate together.

[0046] More specifically, the stirring member in this embodiment includes a stirring plate 9 and a connecting rope 8. During assembly, one end of the connecting rope 8 is first connected to the stirring plate 9, and then the other end of the connecting rope 8 is wound around the driven wheel 7, and can be wound along the rotation direction of the driven wheel 7 when the driven wheel 7 rotates. In this way, when it is necessary to stir the water flow, the driving member 5 can be used to drive the driving wheel to drive the driven wheel 7 to rotate. At this time, the connecting rope 8 is wound along the rotation of the driven wheel 7, so that the connecting rope 8 is contracted to drive the stirring plate 9 to move upward along the height direction of the pool body 1;

[0047] When it is necessary to drive the stirring plate 9 to move downward along the height direction of the pool body 1, the driving member 5 can be used to drive the transmission wheel to rotate in the opposite direction again, thereby driving the driven wheel 7 to rotate in the opposite direction. At this time, the connecting rope 8 is released in the opposite direction, so that the stirring plate 9 moves downward along the height direction of the pool body 1.

[0048] It should be noted that the connecting rope 8 can be a steel rope or a nylon rope or other rope made of a material with high tension, pulling force and load capacity, so that it is not easy to break during use.

[0049] In addition, in the present embodiment, a plurality of agitators, driven wheels 7 and conveyor belts 11 are provided. During specific assembly, the plurality of driven wheels 7 can be rotatably mounted on the connecting rod 42 and distributed at intervals, wherein each two adjacent driven wheels 7 can be respectively connected by a transmission belt 11, and each agitating plate 9 can be connected to the plurality of driven wheels 7 one by one by a connecting rope 8. In this way, the water flow can be disturbed by a plurality of agitating plates 9 at the same time, the disturbance effect is better, and it can be applicable to a pool body 1 with a larger area, so that the entire structure has a wider range of application.

[0050] On the basis of the above structure, a plurality of connecting grooves 71 are provided on each driven wheel 7. During assembly, a driven wheel 7 closest to the transmission wheel can be first connected to the transmission wheel through a conveyor belt 11. At this time, the conveyor belt 11 can be installed in one of the connecting grooves 71 to assemble and drive the transmission wheel with the driven wheel 7 close to the transmission wheel. Then, a plurality of conveyor belts 11 are respectively passed through a plurality of connecting grooves 71 correspondingly on one or more driven wheels 7 far from the transmission wheel, so that a plurality of driven wheels 7 are connected in series with the transmission wheel through a plurality of conveyor belts 11, so that a plurality of driven wheels 7 can be driven to rotate simultaneously through a transmission wheel.

[0051] In addition, the conveyor belt 11 is installed by connecting the groove 71, so that the conveyor belt 11 and the driven wheel 7 are more closely matched after assembly, and are not easy to get loose, so that stable transmission performance can be maintained to meet the needs of high-speed movement.

[0052] Furthermore, a plurality of through holes 12 are provided on the stirring plate 9. The through hole 12 has a first end 121 and a second end 122. The inner diameter of the first end 121 is smaller than the inner diameter of the second end 122. The first end 121 and the second end 122 of each adjacent two through holes 12 are alternately arranged.

[0053] Specifically, by providing a plurality of through holes 12 on the stirring plate 9, when the stirring plate 9 moves up and down along the height direction of the pool body 1, the shrimp eggs can pass through the plurality of through holes 12, thereby reducing the probability of damaging the shrimp eggs during the stirring process of the water flow.

[0054] In addition, since the inner diameter of the first end 121 is smaller than the inner diameter of the second end 122, and the first end 121 and the second end 122 of each adjacent through hole 12 are arranged alternately, the shrimp eggs will be accelerated or decelerated when passing through the through hole 12, so that the shrimp eggs are distributed more evenly in the space.

[0055] Preferably, the diameter of the plurality of through holes 12 on the stirring plate 9 can be set to between 10 mm and 30 mm according to the size of the shrimp eggs, or the aperture size can be set according to the size of other cultured objects. The specific design can be based on actual needs.

[0056] More specifically, in this embodiment, the top and bottom of the stirring plate 9 are both wavy, so that the screen plate can drive more complex water flow when moving in the pool water, avoiding dead zones of water flow and achieving better stirring effect.

[0057] Furthermore, a controller 6 is included, and the rotation speed of the driving motor is adjusted by the controller 6.

[0058] The controller 6 for specifically controlling the driving motor includes but is not limited to a single chip microcomputer, a time relay, etc. The controller 6 automatically controls the frequency of the stirring plate 9 stirring the shrimp eggs by adjusting the rotation speed of the driving motor, and the structure is more intelligent.
