Description

Technical Field

[0001] The utility model relates to the technical field of oxygenators, in particular to an oxygenator for hairy crab breeding. Background Art

[0002] In the hairy crab farming industry, ensuring the oxygen content of the water is crucial to improving the growth rate and survival rate of hairy crabs. One of the traditional methods of oxygenation is to use mechanical stirring to increase the contact area between water and air by stirring the water, thereby promoting the dissolution of oxygen. However, this mechanical stirring aerator has significant limitations in regulating the oxygenation depth.

[0003] A Chinese patent discloses an efficient aerator for hairy crab farming with the authorization announcement number CN206791391U. The patented technology uses magnetic attraction to lift and hit the water body and cooperates with a floating base with a water wave rebound effect to achieve the purpose of directional oxygenation of the water body. The utility model has the advantages of simple and effective structure, convenient and fast oxygenation operation, good directional oxygenation effect of water body and easy installation and maintenance.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the working principle of a mechanical stirring aerator is to drive the stirring device to rotate through a motor to generate strong water flow and vortex. Although this stirring effect can increase the oxygen content of the water body to a certain extent, due to the limitations of stirring intensity and range, the mechanical stirring aerator can often only effectively disperse oxygen in the upper layer of the water body and cannot adjust the depth of oxygenation. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the prior art has the disadvantage that the depth of oxygenation cannot be adjusted. For this reason, we propose an oxygenator for hairy crab breeding.

[0026] Reference Figure 3 As shown, in this embodiment: a thrust spring 10 is provided at the top of the adjusting rod 4, the top of the thrust spring 10 is fixedly connected to the top of the inside of the adjusting column 3, and a handle 11 is fixedly connected to the top of the aerator body 1. When the staff moves the adjusting rod 4 upward, the adjusting rod 4 squeezes the thrust spring 10 for compression and force storage. When the staff releases the limit of the plug 8 and the slot 9, the thrust spring 10 quickly pushes the adjusting rod 4 under the action of the rebound force, so that the staff can quickly adjust the position of the adjusting rod 4.

[0027] Reference Figure 5 and Figure 6 As shown, in this embodiment: the front end and the rear end inside the spring groove 6 are both provided with a slide groove 12, the front end and the rear end of the plug block 8 are both fixedly connected with a slider 13, the surface of the slider 13 is slidably connected with the inside of the slide groove 12, when the staff moves the plug block 8, the plug block 8 drives the slider 13 to move inside the slide groove 12, so that the movement of the plug block 8 is smoother, the friction and resistance are reduced, and the service life of the equipment is improved.
