Description

A multi-degree-of-freedom rotating intensive foam collector for aquaculture ponds

technical field

The invention relates to the field of fishery aquaculture, in particular to a multi-degree-of-freedom rotation intensive foam collector for aquaculture ponds.

Background technique

In the process of intensive fish farming, due to the circulating replenishment of the water body and the accumulation of fish residue bait, the water in the breeding pond will accumulate foam, which will affect the water quality and need to be cleaned in time. Therefore, the foam collector is used in modern intensive aquaculture facilities. As disclosed in Patent No. ZL201420176834.3, a new type of floating foamer is composed of a foam discharge pipe, a hook, a hose and a sewage pipe. The characteristic of this type of foam collector is that it can swing up and down along the hose, That is, when the water level changes, the adaptive change of the hose is used to achieve the floating effect, but some problems will be encountered in practical applications. The foamer still maintains the original position, and the fixed foam discharge pipe cannot be rotated, which will cause the foam collector to stay above the water level, and the foam cannot enter the foam collector from the foam collector to be discharged, resulting in the failure of the foam collector.

SUMMARY OF THE INVENTION

Purpose of the invention: The present invention overcomes the problems of high stress on the hose of the existing floating foamer and insensitivity to small-scale fluctuations in the water level. The foam collector can not only sweep radially with the installation position close to the wall of the culture pond as the fixed point, but also rotate axially with the radial direction of the foam collector itself as the axis, and at the same time reduce its own structural stress.

Technical scheme: a multi-degree-of-freedom rotating intensive foam collector for aquaculture ponds, including a main structure and a rotating lifting mechanism, the main structure including a bracket, a connecting rod, a foam discharge pipe, a main foam collection pipe and a secondary foam collection pipe ; The rotating lifting mechanism includes a deep groove ball bearing, a sliding bearing, an internal meshing ratchet mechanism and a sleeve;

The outer ring of the deep groove ball bearing is connected with the shell hole on the toggle plate through the stop ring, and the central shaft of the deep groove ball bearing is connected with the front end of the connecting rod through a screw;

The front end of the connecting rod is connected to the central shaft of the deep groove ball bearing, and the rear end is connected to the outer ring of the sliding bearing;

The central shaft of the internal meshing ratchet mechanism is connected to the auxiliary foam collecting pipe, and the outer ring of the internal meshing ratchet mechanism is connected to the main foam collecting pipe;

The sleeve is a PVC material hose, and both ends are connected with sealing rubber rings, which are sealed with silicone after being connected with the foam discharge pipe;

An exhaust hole is opened at the upper end of the foam collecting port of the main foam collecting pipe.

As an optimization: the length of the main foam collecting pipe is 3.5m.

As an optimization: the deep groove ball bearing type is 6204.

As an optimization: the distance between the bottom of the rib plate and the water surface of the perch culture pond is 10 cm.

As an optimization: the connecting rod is a steel sheet with a thickness of 3mm and a length of 20cm.

As an optimization: the main foam collecting pipe is a rigid PVC hollow pipe.

Beneficial effects: The present invention replaces the existing hose with a mechanical structure in which two bearings drive the connecting rod, which solves the problem of large stress on the hose itself. , Divide the foam collecting pipe into the main foam collecting pipe and the auxiliary foam collecting pipe, and install the inner meshing ratchet mechanism in the middle. The operator can turn the main foam collecting pipe at any time, so as to adjust the position of the foam collecting port and the exhaust port, and there will be no foam collecting. If the mouth stays above the water level, the foam cannot enter the foam collector from the foam collecting port to be discharged, causing the problem of the failure of the foam collector. In general, the present invention provides a multi-degree-of-freedom rotational intensive aquaculture pond foam collector that can both sweep radially and rotate in the axial direction.

Detailed ways

The present invention will be further described below in conjunction with specific embodiments.

Example

A specific description is given through a method of collecting foam in an intensive perch aquaculture pond.

As shown in Figure 1, it is a foam collector installed in an intensive perch aquaculture tank. Foam collection tube 5. In this embodiment, the length of the main foam collecting pipe 4 is 3.5m, and there is a shell hole on the bracket plate 1. By installing a stop ring in the shell hole, the bracket plate 1 is connected with the outer ring of the deep groove ball bearing 6. The groove ball bearing 6 model is 6204. One end of the connecting rod 2 is connected to the center shaft of the deep groove ball bearing 6 by screws, and the other end is connected to the outer ring of the sliding bearing 7. The main foam discharge pipe 4 and the auxiliary foam discharge pipe 5 are connected by internal meshing ratchets The mechanism 8 is connected, the auxiliary foam discharge pipe 5 is connected with the foam discharge pipe 3, and there is a PVC sleeve 9 in the middle of the foam discharge pipe 3.

As shown in Figure 2, it is a partial schematic view of the internal ratchet mechanism 8. The central shaft 11 of the internal ratchet mechanism 8 is connected to the auxiliary foam discharge pipe 5, and the outer ring 12 is connected to the main foam collecting pipe 4. The outer ring 12 of the mechanism can only It can be rotated counterclockwise around the central axis and cannot be rotated in the opposite direction, and can be used to fix the position of the foam collecting port and the exhaust port 10.

When installing the foam collector, first fix the position of the rib plate 1, and then install other main structures. The bottom of the rib plate 1 is about 10cm away from the water surface of the perch breeding pond. Both sides of the installed PVC casing 9 need to be installed with sealing rubber rings and sealed with silicone.

The connecting rod 2 is a steel sheet with a thickness of 3mm and a length of 20cm. The foam collecting pipe is a rigid PVC hollow pipe, which extends to the middle of the breeding tank to ensure that the foam collecting pipe can float and collect the foam thoroughly.

After the installation is completed, ensure that the main foam collecting pipe 4 and the auxiliary foam collecting pipe 5 float on the water surface, and then rotate the main foam discharging pipe 4, so that half of the foam collecting port is below the water surface and half is above the water surface, and the exhaust port is at this time. 10 is also above the water. Because the foam is light and floats on the water surface, it is stopped by the main foam collecting pipe 4 driven by the rotation of the water flow in the intensive aquaculture pond, and slowly enters the main foam collecting pipe 4 from the foam collecting port under the action of the water flow. It enters from the main foam collecting pipe 4 to the auxiliary foam collecting pipe 5 and is discharged out of the pool from the foam discharge pipe 3.

When the water level fluctuates, the main and auxiliary foam collecting pipes are still floating on the water surface through the adjustment effect of the connecting rod 2 and the bearing, and the bearing rotation stress is small. When the main foam collecting pipe 4 is gently rotated, the position of the foam collecting port can be restored.

The above is only an embodiment of the present invention, and is not intended to limit the intensive perch culturing pond to which the present invention is applied. For those skilled in the art, the present invention can also be applied to other fish farming processes, And there can be various improvements and changes, including changes in the length of the connecting rod, bearings, etc., in order to adapt to different fish species, all modifications, finishes, improvements, etc. made within the principles and scope of the present invention should include within the protection scope of the present invention.
