Technical Field

[0001] The utility model relates to the technical field of water level monitoring, in particular to a freshwater aquaculture water level alarm device. Background Art

[0002] Freshwater aquaculture refers to the breeding and reproduction of aquatic economic animals (fish, shrimp, crab, shellfish, etc.) and aquatic economic plants in ponds, reservoirs, lakes, rivers, and other inland waters (including brackish water). It is an important part of the inland aquaculture industry and provides humans with a large amount of high-quality animal protein. It is one of the main sources of high-quality animal protein for humans in the future and is of great significance to improving people's food structure.

[0003] Sufficient clean water needs to be injected into the freshwater aquaculture pond to ensure the normal growth of aquatic animals and plants therein. However, when injecting clean water into the freshwater aquaculture pond, injecting too much clean water will cause a waste of water resources. In addition, the freshwater modules are raised in the open air. In rainy environments, it is inconvenient for staff to monitor water level changes in real time. It is necessary to install a water level alarm device to monitor the water level in the freshwater aquaculture pond. The existing water level alarm device is in an open air environment. When it rains, it is easy to cause the water level alarm device to short-circuit, affecting its subsequent normal use. At the same time, the alarm sound of the existing alarm water level alarm device is easily blocked, making it difficult to effectively notify surrounding operators, affecting the efficiency of alarm and notification.
