Low-water-level warning system for grouper culture in workshop

Abstract

The invention provides a low-water-level warning system for grouper culture in a workshop. The system comprises a power supply, indicating lights, water level warning detectors, a buzzer and a switch,wherein the positive pole of the power supply is connected with the indicating lights in series, the indicating lights are connected in parallel, and the indicating lights are connected with the water level warning detectors in series. The water level warning detectors are connected in parallel, and the total output end of the water level warning detectors is sequentially connected with the buzzer, the switch and the negative pole of the power supply in series. The system is provided with the water level warning detectors which have the advantages of being low in cost, high in stability and quick in response, the water level warning detectors are specially used in grouper culture ponds, when water in a pond is lower than the corresponding water level warning detector, the buzzer arrangedoutside the ponds gives an alert to a farmer and reminds the farmer of the specific position of the low-water-level pond, and the water level warning detectors are used as a unit so that the water level warning detectors can be prepared into modularized product to be applied and popularized.

Description

technical field [0001] The invention relates to the technical field of a workshop breeding alarm system, in particular to a low water level alarm system for grouper breeding in a workshop. Background technique [0002] In recent years, with the gradual expansion of the market for high-end fish, the aquaculture industry of various high-end fish has gradually become popular. Among them, grouper, as one of the carnivorous tropical fish, has also begun to develop rapidly. In the southwestern coastal areas of our country, especially in the coastal areas of Hainan Island, a large number of workshop farming models have become the main force for grouper farming, but at the same time, there have also been many farming problems. brought about great economic losses. [0003] In the breeding process of grouper, in order to reduce the mortality rate of grouper, its living environment must be kept clean. Therefore, it is necessary to drain the pool once every day at 7 o'clock in the morn...

Problems solved by technology

In the southwestern coastal areas of our country, especially in the coastal areas of Hainan Island, a large number of workshop farming models have become the main force for grouper farming, but at the same time, there have also been many farming problems. caused great economic loss

[0003] In the breeding process of grouper, in order to reduce the mortality rate of grouper, its living environment must be kept clean. Therefore, it is necessary to drain the pool once every day at 7 o'clock in the morning and at 18 o'clock in the evening, that is, Open the floor drains of the pools; since each household has a large number of pools, one person can open the floor drains of 6-8 pools at the same time, but due to various reasons, there will always be one or two times when one or two forget to close them. The floor drain of a pool, although the pool is continuously filled with water, the discharge volume must be greater than the water intake. Therefore, once you forget to close the floor drain and fail to find it in time, it will lead to the death of the fish in the entire pool due to hypoxia, which will bring great harm to the aquaculture industry. Huge loss, therefore, an inexpensive and stable and durable water level alarm is urgently needed in this industry
