Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of animal breeding, in particular to a breeding nest box for otters. BACKGROUND

[0002] Otters are animals of the order Carnivora, family Mustelidae, and subfamily Lutrinae. There are 13 species of otters in the world, which are widely distributed in freshwater rivers, lakes, coastal wetlands and other environments around the world. They are known for their superb swimming skills, sociality and playful nature.

[0003] Otters are flagship species and indicator species. They are at the top of the freshwater food chain, and the health of their population directly reflects the health of the entire wetland ecosystem. Protecting otters means protecting the rivers, lakes and organisms in them on which they depend.

[0004] The Eurasian otter is the most widely distributed member of the otter family, but it has become a rare animal in need of protection in many areas today. The Eurasian otter is distributed across Europe, Asia and parts of Africa. In China, they are mainly distributed in rivers, lakes and coastal wetlands in Northeast China, East China, South China and Southwest China.

[0005] The Eurasian otter is a diurnal animal that rests in a cave during the day and comes out at night. Except during the mating season, the Eurasian otter prefers to live alone and is usually solitary. Eurasian otters are mostly cave-dwelling, but they do not have fixed caves. In order to find more food, they often migrate along rivers and lakes. Only when female Eurasian otters breed their young do they choose to settle in a safe and hidden nest, which is in a rock crevice on the bank or under a tree root, and they dig or use old nests of foxes, badgers and hares and repair them.

[0006] During the process of female Eurasian otters breeding their young alone, monitoring and protection are of great significance to improving the success rate of breeding, promoting the recovery of the population and maintaining the balance of the ecosystem. However, the solitary nature of the Eurasian otter and the concealment of the breeding nest make it difficult for researchers to find the breeding nest of the Eurasian otter, and the female otter during the breeding period is extremely aggressive, making it difficult to monitor and protect the otter in the breeding nest after finding the breeding nest of the Eurasian otter.

When the first infrared camera 42 acquires the image information that the otter defecates on the feces collecting mechanism 2, the controller 41 uploads the image information of the otter defecation to the cloud server through the communication module. After the cloud server recognizes, the first control instruction is issued to the controller 41 to make the controller 41 control the feces collecting mechanism 2 to collect and save the otter feces. When the first infrared camera 42 acquires the head information of other organisms at the first hole 14, the controller 41 uploads the head information of other organisms to the cloud server through the communication module. The cloud server matches and identifies whether there is a threat. If there is a threat, the cloud server issues a second control instruction to the controller 41. The controller 41 controls the first micro-cylinder 33 to extend and limit and fix the adjusting plate 32 in the camouflage shell 31 to block the competitors larger than the otter from entering the nest box 1. The otter life history images acquired by the first infrared camera 42 and the second infrared camera 43 are uploaded to the cloud server by the controller 41 for storage. The two temperature and humidity sensors 44 monitor the temperature and humidity in the resting chamber 12 and the breeding chamber 13, respectively. Through the acquired image information and environmental information, scientific basis is provided for otter protection and research.

[0080] As shown in the accompanying drawings, Figure 2 The ventilation opening 17 is provided with an electric shutter 5, which is connected with the monitoring mechanism 4 and used to adjust the temperature in the breeding chamber 13.

[0081] It can be understood that when the temperature in the breeding chamber 13 is too high or too low, the controller 41 adjusts the opening degree of the electric shutter 5 for corresponding adjustment. After the opening degree of the electric shutter 5 is increased, the air flow in the breeding chamber 13 is increased to cool the breeding chamber 13. After the opening degree of the electric shutter 5 is reduced, the air flow in the breeding chamber 13 is reduced to heat the breeding chamber 13 and reduce heat loss, thereby providing a breeding place with suitable temperature for the otter.
