Oxygen supply interruption alarm device for sea cucumber seedling raising pond

Abstract

The invention discloses an oxygen supply interruption alarm device for a sea cucumber seedling raising pond. A direct current closed loop consists of three parts, namely an air flow flowing monitoring pipe fitting, a lead-acid storage battery and a buzzer, wherein an inner structure of the air flow flowing monitoring pipe fitting comprises a rotary contact piece, a positive contact piece, a negative contact piece, a rotating shaft, a protective shell and the like; when air flow passes through the rotary contact piece, the closed loop is cut off, and the buzzer is turned off; when no air flow passes through the rotary contact piece, the closed loop is connected, and the buzzer is turned on; the pipe diameter of the air flow flowing monitoring pipe fitting is DN25-DN150 and is the same as that of a blast pipe; the air flow flowing monitoring pipe fitting can be used as a pipe fitting to be arranged on the blast pipe; the lead-acid storage battery output voltage of 6-12V; and the buzzer is a piezoelectric alarm sound buzzer with rated voltage of 6-12V and sound level of more than or equal to 90dB. By adopting the device, the problem of heavy loss of seedlings caused by oxygen supply interruption in the case of shortage of a seedling raising pond oxygen supply interruption alarm device in a seedling raising workshop in a sea cucumber chamber is solved; and the device is suitable for seedling raising and production of the sea cucumber.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an oxygen-break alarm device for a sea cucumber nursery pond. Background technique [0002] Sea cucumber farming is a new aquaculture industry that has gradually developed in my country's coastal areas in recent years. The value of aquaculture production has continued to increase. With the substantial increase in aquaculture area, the demand for sea cucumber seedlings has risen sharply, and the sea cucumber seedling industry has also developed rapidly. At present, sea cucumber seedlings mostly adopt the indoor factory production method. A large number of seedling ponds with the same specifications are distributed in the seedling cultivation workshop, and the cultivation environment of the seedling ponds is uniformly regulated, such as water temperature, dissolved oxygen, bait, etc. The concentration of dissolved oxygen in the seedling ponds It is very important for sea cucumber seedlin...

AI Technical Summary

Problems solved by technology

At present, sea cucumber seedlings mostly adopt the indoor factory production method. A large number of seedling ponds with the same specifications are distributed in the seedling cultivation workshop, and the cultivation environment of the seedling ponds is uniformly regulated, such as water temperature, dissolved oxygen, bait, etc. The concentration of dissolved oxygen in the seedling ponds It is very important for sea cucumber seedlings. If the oxygen supply in the pool is stopped for more than half an hour, it will cause damage to the seedlings, resulting in a decline in the vitality of the seedlings, and even the death of the seedlings in severe cases.

At present, most nursery farms lack monitoring devices for the oxygen supply operation in the nursery pool. When the nursery workshop encounters a power failure or an air compressor failure to stop the oxygen supply, especially at night, the staff cannot detect the fault in time due to falling asleep, and cannot take emergency remedial measures. , it will lead to major seed loss accidents in the seedling cultivation workshop
