Embodiment 1
[0022] Embodiment 1: refer to Figure 1 to Figure 5 , impellerless type aerator, comprising a floating body 4, also has a spray cover 1; the spray cover 1 contains an annular outer cover 12 and an inner ring 11 installed on the inner side of the outer cover 12, and between the outer cover 12 and the inner ring 11 It has a cavity; the end edge of the outer cover 12 is fitted and connected with the end edge of the inner ring 11, and there is an annular spout 13 opening along the inner wall of the inner ring 11 between the front end edge of the outer cover 12 and the front end edge of the inner ring 11; The water spray cover body 1 is connected on the floating body 4 through the multidirectional suspension 2 which can control the elevation angle of the water spray cover body 1; Component 3. The double-layer hollow structure adopted by the water spray cover 1 sprays water out along the inner wall of the inner ring 11 through the annular spout 13 after the external water supply as...
Embodiment 2
[0030] Embodiment 2: refer to Figure 6 , this embodiment makes some changes on the basis of Embodiment 1, specifically, the water supply assembly 3 includes a water pump 31, a conduit 33, a water diversion pipe 34, and a filter screen 35; the water pump 31 is installed on the floating body 4, and the water pump 31 diversion pipe 34 A strainer 35 is provided on the port of the filter; the water pump 31 is connected to the water injection pipe 14 on the water spray cover body 1 through a conduit 33 . By installing the water pump 31 on the floating body 4, it is possible to prevent the oil pollution of the water pump 31 from entering the water body, which is beneficial to ecological breeding. Filter screen 35 can prevent the inhalation of fish and shrimp, therefore also can adopt the structure of above-mentioned filter cover 32 that has through hole. It is also possible to arrange an air duct connected to the water surface air near the annular nozzle 13. Under the negative pres...
