The invention relates to an amphibious individual soldier carrying backpack. The amphibious individual soldier carrying backpack comprises a main backpack, an auxiliary backpack, a folding air bag and a fixing device. The main backpack comprises a main backpack body and a main backpack cover. The folding air bag is of an annular structure. The fixing device comprises a cushion plate, short-side fastening belts sewn and fixed to the front side and the rear side of the cushion plate in the width direction, and long-side fastening belts sewn and fixed to the left end and the right end of the cushion plate in the length direction. A rescue and camping dual-purpose air bag is provided with multiple hanging rings or hanging holes. A high-pressure air cylinder for inflating an inflatable bag body through a one-way air tap is placed in an auxiliary side backpack body. The amphibious individual soldier carrying backpack achieves the amphibious carrying functions that the backpack can be dragged in a floating mode on the waterside and can be carried on the back by an individual soldier or lifted by two soldiers on land, achieves the protection functions of waterproofness, dampproofness and the like, and meets the requirements of infantries in the army of China for carrying and protection of arms and ammunition in the swimming-in-battle-gear and beach-head processes.

The invention discloses an anti-suffocation and cold prevention monitoring device and monitoring method for non-contact scanning temperature field. In the monitoring device, a second motor driving module is connected on a support module and is can be rotated relative to the support module; the first motor driving module is connected above the second motor driving module and can be rotated relative to the second motor driving module; an infrared temperature measurement module is fixed above the first motor driving module; an infrared temperature measurement lens in the infrared temperature measurement module is installed facing a target area; the infrared temperature measurement module and an acousto-optic warning prompting module are connected to a controller; and the first motor driving module and the second motor driving module are controlled by the controller module. The monitoring device and monitoring method can timely and accurately find out whether the head part of the human body is shielded by the covering, and make the acousto-optic alarm to prompt the guardian to adopt the protection measurement to prevent suffocation and achieve the goal of protecting human body, particularly protecting the baby.

The invention discloses a one-way sound-absorbing wall filling material, which belongs to the field of noise reduction and environmental protection. The one-way sound-absorbing wall filling material can be arranged by a plurality of conch-shaped two-way sound tubes, and the sound can be reduced from the inside to the outside. It is conducted from the thick end to the thin end, and the inner diameter of the thin end is larger, which can play a better sound amplification effect. At the same time, from the outside to the inside, the sound is conducted from the thin end to the thick end, so that the sound passes through many times. The inner wall of the thin end and the thick end is reflected to achieve an effective noise reduction effect. At the same time, with the function of the semi-sound insulation board, it can achieve the effect of different sound insulation between indoor and outdoor, thereby effectively improving the application range of this sound insulation material, so that people in the room can be protected from the outside world. At the same time as the noise is disturbed, people outside can detect the movement in the room in time, thereby improving the rest quality of people indoors, and at the same time reducing certain safety hazards.

The invention discloses a large-scale dairy cow breeding system, which includes a cow bed, a cow excrement collection device and a spray cooling device respectively arranged in the cowshed. The dairy cow excrement collection device is located at the end of the cow bed, and the spray cooling device is located at the bottom of the cow bed. Directly above; the large-scale dairy cow breeding system of this application can reduce the cost of dairy cow breeding and make the living environment of dairy cows more comfortable by effectively setting the structure of the cow bed, cow excrement collection device and spray cooling device in the cowshed. Thereby, the quality of milk and its dairy products can be improved, and the income of dairy farmers can be increased.
