Description

Technical Field

[0001] The utility model relates to the technical field of water lifting devices, in particular to a water lifting device suitable for an aerator. Background Art

[0002] An aerator is a machine commonly used in fishery farming. Its main function is to increase the oxygen content in the water to ensure that the fish in the water will not suffer from hypoxia. In order to enable the aerator to stably increase oxygen on the water surface and avoid damage to the aerator motor, a water lifting device is needed to lift the aerator to the water surface.

[0003] According to the description of an aerator water lifting device disclosed in the patent website (authorization announcement number: CN 219077429 U), "an aerator water lifting device includes three lifting rods (1) in a circular array, the front end of the lifting rod (1) is provided with a connecting plate (2) for connecting to the aerator, the rear end of the lifting rod (1) is provided with a float mounting seat (3), and a plurality of detachably connected solid floats (4) are arranged in a circular array on the float mounting seat (3). The utility model has the advantages that: through the cooperation of a plurality of solid floats, the number of floats can be increased or decreased according to the weight of the aerator, and the suspension height can be quickly adjusted, which is convenient and quick to use. At the same time, the float is solid and has no disadvantage of water leakage, and has higher stability during use."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model can install the solid float according to the weight of the aerator and adjust the suspension height of the aerator by setting up multiple solid floats. However, in actual use, the device can only install smaller solid floats when installing the solid floats. When the aerator is heavier, a slightly larger float cannot be installed due to the fixed length of the connecting rod. Installing a larger float will cause the floats to be squeezed together, affecting stability. Therefore, it is necessary to improve a water lifting device suitable for the aerator to solve the above problem. Utility Model Content
