Description

Technical Field

[0001] This utility model relates to the field of marine aquaculture technology, specifically to an oxygenation device for sea cucumber farming. Background Technology

[0002] Sea cucumber farming currently mostly adopts outdoor natural sea area farming. In order to facilitate the recovery of grown sea cucumbers, net cage farming is mostly used. For deeper ocean areas, it is necessary to supplement the seawater with oxygen to maintain the growth of sea cucumbers. However, due to the development environment of the ocean and the effects of ocean currents and tides, the absorption rate of supplemented oxygen by sea cucumbers is very low, resulting in large oxygenation equipment and poor effectiveness. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides an oxygenation device for sea cucumber farming.

[0004] The technical solution adopted by this utility model is as follows:

A hanging ring is fixedly connected to the upper part of the frame, and a mesh plate is fixedly connected to the lower part inside the frame. Several evenly distributed farming heads are fixedly connected inside the mesh plate. Each farming head is connected to an air intake branch pipe at its lower part, and each air intake branch pipe is connected to the connection point of air intake main pipe one and air intake main pipe two. The lower part of the mesh plate has several air intake main pipes one and several air intake main pipes two. The air intake main pipes one and two are arranged parallel at equal intervals, and the air intake main pipes two are arranged parallel at equal intervals. The air intake main pipes one and two are connected perpendicularly to each other. One side of the air intake main pipe two is connected to the main air intake pipe. The main air intake pipe extends upwards, and its upper end is connected to an oxygenation pump. A rain cap is fixedly connected above the inlet of the oxygenation pump. The inlet of the oxygenation pump is equipped with a filter screen, and the upper part of the filter screen is a rain cap.

[0006] The breeding head includes a funnel-shaped shell composed of an air intake branch pipe, a conical pipe, and an outer pipe. The bottom of the outer pipe is connected to the conical pipe, and the outer pipe and the conical pipe are integrally structured. The bottom of the conical pipe is connected to the upper part of the air intake branch pipe. A breeding tray is placed inside the outer pipe, and the inner wall of the outer pipe is inserted and fitted with the outer wall of the breeding tray. The bottom surface of the breeding tray is a screen, and the bottom of the breeding tray is fixedly connected to the screen. A fine sand pad is laid on the upper part of the screen, and a pebble pad is laid on the upper part of the fine sand pad.

[0007] The lower outer wall of the intake manifold is threaded, and the intake manifold is connected to and communicates with the intake main pipe 1 and intake main pipe 2 through the thread. The upper part of the thread is a boss, which is fixed to the outer wall of the intake manifold. A rubber disc is provided above the intake manifold, and the rubber disc fits against the top of the intake manifold, covering the opening at the top of the intake manifold. The upper center of the rubber disc is fixedly connected to the pressure plate. The outer diameter of the pressure plate is smaller than the inner hole of the intake manifold. A column is fixedly connected above the pressure plate, and a support arm is fixedly connected above the column. Two lugs are fixedly connected to the inner wall of the conical tube, and the two ends of the support arm are respectively connected to the two lugs by bolts.

[0008] If a turbulence plate is fixedly connected to the support arm, the turbulence plate is irregularly arranged, and a support block is fixedly connected to the upper part of the turbulence plate, with the support block abutting against the bottom of the screen.

[0009] The bottom of the frame is equipped with steel spikes.

[0010] The beneficial effects of this utility model are:

[0011] By placing sea cucumbers inside the culture head, the oxygenated airflow dissolves fully in the seawater from the bottom of the culture head and is absorbed by the sea cucumbers, thus increasing their oxygen levels. Attached Figure Description
