Description

A kind of raising and lowering mechanism of aquaculture hanging cage and linkage hanging cage lifting system

technical field

The invention relates to an aquatic product culturing device, in particular, to a raising and lowering mechanism of a raising cage and a linked cage raising and lowering system.

Background technique

In the production process of aquatic product aquaculture, especially in the process of underwater aquaculture in the form of hanging cages, a vertical pull rope is usually set under the floating ball. The resulting buoyancy pulls the hanging cage and suspends it in the water. Due to the seasonal influence of the water surface temperature, the health and growth rate of the cultured objects in the hanging cage are greatly affected by the temperature. Especially in summer when the water temperature is high, it is necessary to extend the vertical The length of the pull rope lowers the cage to deeper waters with lower temperatures. The current traditional method is to fold and wind a part of the vertical pull rope to tie a slip knot when farming in shallower waters. When the surface water temperature rises, the cage needs to be removed. When sinking to deeper water, open the slipknot and extend the vertical rope completely, and the hanging cage is lowered to a predetermined depth. If the cage needs to be re-pulled to a shallower depth of water, it is necessary to fold and wrap the vertical rope again to tie a slip knot, so that the length of the vertical rope can be changed over and over again according to the actual needs to realize the depth change of the cage.

The process of changing the depth of the cage by adjusting the length of the vertical rope requires manual operation. The key problem is that each vertical rope needs to be adjusted each time.

As shown in FIG. 1 , the present invention provides a raising and lowering mechanism of a breeding cage, including: a floating ball 1 , a horizontal pull rope 2 , a longitudinal pull rope 3 , a hanging cage 4 and a lifting adjustment pull rope 5 . Wherein, two ear holes are symmetrically arranged under the floating ball 1 , and after the transverse pull rope 2 passes through the two ear holes in sequence, the two ends are respectively fastened to the fixed stakes. One end of the longitudinal drawstring 3 is tied to the part of the horizontal drawstring located between the two ear holes, and the other end is connected to the hanging cage 4 . The lifting adjustment cable 5 passes through the two ear holes in sequence, and the lifting adjustment cable includes an adjustment part 51 located between the two ear holes and a connecting part 52 located outside the two ear holes. A specific position of the longitudinal drawstring fixes the connected fixing portion 53, so that when the connecting portion is pulled outwards, the adjusting portion can replace part of the longitudinal drawstring located above the specific position to receive force. Further, both ends of the lifting and adjusting rope are connected to a stepping motor 6 . Further, the lifting mechanism also includes a controller and a temperature sensor; the temperature sensor is arranged on the hanging cage to collect the water temperature at the depth of the hanging cage; the signal collection port of the controller is connected to the temperature sensor, and the control port is connected to the step. into motor 6. Further, the mechanism also includes a floating body platform 9 on which the stepping motor 6 is placed, and a sheave 7 on which the lifting and adjusting rope 5 is wound.

Specifically, the lifting and lowering adjustment ropes 5 pass through the two ear holes at the lower end of the floating body 1 in sequence, and are respectively fixed to the vertical ropes 3 below the floating body. Decide. When the intelligent control circuit board detects that the water temperature of the deepest aquaculture waters transmitted by the temperature sensor is too low and the water temperature of the shallowest aquaculture waters is suitable for the growth of aquaculture objects, the intelligent control circuit board sends a control signal to drive the stepping motors 6 on the floating body platforms 9 on both sides to rotate, The stepping motor 6 drives the sheave 7 to rotate and wind the lifting adjustment rope 5. When the two ends of the lifting adjustment rope 5 are wound to both sides by force, the lifting adjustment rope 5 gradually shortens and tends to be in a straight line state from a curved state. The uneven force on both ends of the lifting adjustment cable 5 causes the knot at position A to deflect towards a certain ear hole and try to pass through the ear hole. Since the size of the knot at position A is larger than the inner diameter of the ear hole, it can be ensured that the knot at position A will not pass through the ear hole. pass and remain between the two ear holes. During the process of the lifting and adjusting rope 5 changing from a curved shape to a straight state, the position A that is fastened to the vertical rope 3 will gradually rise until the lifting and adjusting rope 5 is stretched as a whole to a shape close to a horizontal straight line, and the hanging cage 4 reaches In the shallowest aquaculture waters, at this time, the vertical pull rope 3 upward from the tightening position A of the vertical pull rope 5 and the vertical pull rope 3 is in an unstressed bending state, as shown in Figure 3, at this time, the stepper motor 6 If it is set in the locked state, the breeding cage 4 is kept in the shallowest breeding water, so that the whole row of hanging cages can be raised to the shallowest breeding water.

When the intelligent control circuit board detects that the water temperature of the shallowest aquaculture waters transmitted by the temperature sensor is too high or low and the water temperature of the deepest and shallowest aquaculture waters is suitable for the growth of aquaculture objects, the intelligent control circuit board sends a control signal to drive the stepping motors 6 on the floating body platforms 9 on both sides to reverse The stepper motor 6 drives the sheave 7 to rotate to release the lifting adjustment rope 5. Both ends of the lifting adjustment rope 5 are in a relaxed state without tension. The breeding cage 4 gradually sinks under the action of gravity, and point A follows the breeding cage. 4 gradually descends, the tension of the pull rope 3 above point A gradually tends to be straight from the free state of bending, until the entire vertical pull rope 3 extends into a vertical straight line, and the breeding cage 4 reaches the deepest breeding water area, as shown in the figure. 2 shown. During this process, the two ends of the adjustment rope 5 are not subject to tension. Since the position of point A falls, the adjustment rope 5 is pulled by the position of point A and gradually slides from the outside of the ear hole to the inside of the ear hole until the breeding cage 4 reaches the deepest breeding water area, and the adjustment rope 5 A free state that gradually tends to bend from a horizontal straight line. The maximum depth of the settlement of the breeding cage 4 is determined by the vertical pull rope, and the maximum stroke of the ascent is determined by the tightening position of the lifting adjustment pull rope 5 and the vertical pull rope 3, and the user can determine it according to the needs of the breeding object. The number of rotations of the stepping motor 6 is set in the control program of the electronic control system 8 according to the lifting stroke requirements set by the user.

Specifically, the system includes a plurality of linked lifting mechanisms, that is, a plurality of floating balls 1 , a horizontal pull rope 2 , a vertical pull rope 3 , a cage 4 connected to the vertical pull rope, and a lifting adjustment pull rope 5 , a stepping motor 6 that drives the lifting rope to relax, a sheave 7 that winds the lifting rope, a controller 8, and a floating platform 9 that houses the controller 8 and the stepping motor 6. When in use, multiple sets of floating 1, vertical rope 3, and hanging cage 4 are connected in series by horizontal rope 2 and lifting adjustment rope 5 to form a row. The specific number of series can be determined by the user according to actual needs. A breeding water area is generally arranged in parallel in multiple rows, and there is a floating body platform 9 at both ends of each row. The floating body platform 9 is generally a hollow square plastic cylinder or foam material, which is immersed in water to generate buoyancy, and the upper surface is higher than the water surface. A stepping motor 6 is fixed on the upper surface of each floating body platform, the power output shaft of the stepping motor 7 is provided with a sheave 7, and the two ends of the lifting and adjusting rope 5 are respectively wound on the sheave. A controller 8 is fixed on the upper surface of one floating body platform in each row, and the controller includes a power supply, a water temperature sensor and an intelligent control circuit board. The working process of the system is the same as the working process of the above-mentioned single lifting mechanism, and will not be repeated here.
