The invention discloses a staff metabolism simulation system for ground comprehensive tests of a manned spacecraft. The staff metabolism simulation system mainly comprises an oxygen concentration simulation unit, a carbon dioxide simulation unit, a nitrogen simulation unit and a humidity simulation unit. The staff metabolism simulation system is connected with a sealed cabin through pipelines, and air circulates between the staff metabolism simulation system and the sealed cabin of the manned spacecraft. According to an input simulation staff number and each staff metabolism mode, a control system calculates control targets of the heat production quantity, the humidity production quantity, the oxygen consumption quantity and the carbon dioxide increase quantity in combination with a metabolism based empirical formula, and controls a fan, a valve, a compressor, a molecular sieve, a flow controller, a pump and a heater so as to achieve the control targets through data such as temperatures, pressure, flow and oxygen concentration in an acquisition system according to preset control logic. Compared with staff metabolism simulation systems in prior art, the staff metabolism simulation system has the advantages that no staffs are required for participating in the tests, and capacities of a thermal control system and an environment control system are simultaneously assessed; and compared with tests with the staff, test systems constructed by the staff metabolism simulation system are safer, higher in flexibility, longer in continuous running time and fuller in product assessment, and do not occupy cabin volume.

The invention discloses a fire extinguishing type power distribution cabinet based on the principle of high temperature degaussing, which comprises a cabinet body, a plurality of cooling holes are symmetrically opened on the side wall of the cabinet body, sliding cavities are symmetrically opened on the side wall of the cabinet body, and the sliding cavity is symmetrically opened on the side wall of the cabinet body. The inner wall of the cavity is sealed and slidably connected with a slide plate, and the side wall of the slide plate is provided with a plurality of through holes matching with the cooling holes. The top of the slide cavity is fixedly connected with a permanent magnet block, and the top of the slide plate is fixedly connected with a magnet. The lower end of the magnetic block is fixedly connected with the upper end of the magnet through a spring. In the present invention, the temperature in the cabinet reaches the Curie point of the permanent magnet block, so that the permanent magnet block is demagnetized due to high temperature, and then the magnet drives the slide plate to slide down under the action of the spring, so that the through hole and the heat dissipation hole are misaligned, so that the outside air cannot pass through to dissipate heat. The hole enters the cabinet, and the cabinet is subjected to oxygen isolation treatment, and the hydrochloric acid solution and calcium carbonate particles generate carbon dioxide, which increases the concentration of carbon dioxide in the cabinet and accelerates the extinguishing of the fire in the cabinet.

The invention discloses a high-voltage photoelectric catalytic reduction carbon dioxide experimental device, which includes a gas supply component, a high-pressure reaction component, a data acquisition component, and a product collection component, wherein the gas supply component includes two channels, and the channel for transmitting carbon dioxide is arranged on the A high-pressure pump and four valves symmetrically arranged on two channels; a high-pressure reaction component, including a reduction reactor and an analog light source connected to the reduction reactor; a data acquisition component, including an electrochemical workstation and a data acquisition instrument; and, the product The collection assembly includes a sampling box and a vacuum pump connected to the sampling box; the high-pressure photoelectric catalytic reduction carbon dioxide experimental device in the present invention aims at the problem of low carbon dioxide reduction efficiency, and a high-pressure carbon dioxide reduction reactor is designed. Under high pressure, the reduction efficiency of carbon dioxide is increased from 10% under normal pressure to over 80% (carbon dioxide at 50 atmospheric pressure); in view of the problem of low copper catalyst activity, high-pressure carbon dioxide can significantly regulate the activity of copper catalyst.
