The invention discloses an absorption-compression composite refrigeration system and method based on forward and reverse cycle coupling. The system includes a power sub-cycle and an absorption-compression composite refrigeration sub-cycle. The system and method use the higher temperature part of the medium and low temperature heat source to drive the power sub-cycle to do work, reducing the heat source directly used for the heat exchange temperature difference of the absorption-compression compound refrigeration system; the lower temperature part and the power sub-cycle exhaust heat as the absorption-compression The heat source of the compound refrigeration sub-cycle; the work done by the power sub-cycle drives the compressor in the absorption-compression compound refrigeration sub-cycle. In the absorption-compression composite refrigeration sub-cycle, the compressor is located between the evaporator and the absorber, and the evaporation pressure can be lower than the absorption pressure, so that the evaporation temperature can be lowered, which meets the needs of the low-temperature refrigeration field, and at the same time enables the system to operate Normal operation under higher condensing temperature conditions. The input energy of the whole system is medium and low temperature heat source, and the product output is low temperature cooling capacity, which does not require external input work.

A sintering control method and system. The method comprises: detecting a current position of a burn-through point of a sintering trolley operating at a preset speed; determining a relationship between the current position of the burn-through point and a first preset position N and a relationship between the current position of the burn-through point and a second preset position M, [N, M] being an ideal position range of the burn-through point of the sintering trolley; when the current position of the burn-through point is less than N, reducing air quantity of a large flue or reducing a negative pressure of the large flue ; and when the current position of the burn-through point is greater than M, increasing air quantity of the large flue or increasing the negative pressure of the large flue. In the method, the generation of ineffective negative pressure and ineffective air quantity in the sintering process is reduced, and electric power consumed by a main exhaust fan is saved, thereby avoiding adverse effects of the speed regulation of the trolley on the stability of the material flow quality and the control of the follow-up working procedure.

The invention belongs to the technical field of virtual reality, and in particular discloses a fire drill virtual training method. According to the method, a pair of VR glasses comprises a glasses main body, and further comprises a telescopic rod and an elastic pressing head, wherein a No.1 rectangular groove is arranged in the middle of the glasses main body; the telescopic rod is fixedly connected to the interior of a mounting hole in the left side of the No.1 rectangular groove; the elastic pressing head is hinged at the end of the telescopic rod; and two semi-arc surfaces of the elastic pressing head are arranged in a mode of being mutually tangent. According to the fire drill virtual training method provided by the invention, by arranging the elastic pressing head at the end of the telescopic rod, rapid installation of electronic equipment is achieved; the two semi-arc surfaces of the elastic pressing head are squeezed and get deformed, so that the electronic equipment cannot bearexcessive squeezing force in one aspect, and subsequently, the safety of the electronic equipment is guaranteed; and in the other aspect, a contact area is increased, so that the electronic equipmentcan be clamped more reliably and influence to virtual effect of the glasses due to shaking of the electronic equipment can be prevented; the electronic equipment, when needs to be taken out, can be pulled out with strength; and therefore, the pair of VR glasses is convenient to operate.

The high-efficient safety solar paper shredder comprises a box body, wherein the left side of a separation plate on the bottom ofan inner cavity of the box body is fixedly connected with a control apparatus, two sides, close to the inner wall of the box body, of the top of a leakage separation plate are respectively fixedly connected with a reciprocating apparatus, one side, away from the inner wall of the box body, of the reciprocating apparatus is fixedly connected with a secondary crushing apparatus, the middle positions of the front surface and the rear surface of the inner cavity of the box body are respectively connected with two crushing wheels in a rotating manner, one side, close to a baffle plate, of a flip box door is fixedly connected with a lifting apparatus, one side, away from the flip box door, of the lifting apparatus is fixedly connected with a solar apparatus, the inner surface of a guiding hopper is provided with a first sensor, and the inner surface of a feeding opening is provided with a second sensor. The invention relates to the technical field of paper shredders. When in processing, theapparatus is rapid and efficient, capable of sensing a safety position of the working personnel, and capable of controlling the opening and closing state in time, ensuring the safety of the personnel, supplying the power by virtue of solar energy, preventing the electric shock and protecting the environment.

The invention discloses a plunger type cylinder for water pumping. The plunger type cylinder includes a plunger piston and a pushing rod. The plunger piston is installed in a plunger piston chamber. The pushing rod is fixedly connected with the plunger piston. One end stretching out of the pushing rod is connected with a piston of a water pump. The plunger piston chamber is provided with a high pressure water out-in opening. According to the plunger type cylinder, through pushing of the plunger piston in the plunger piston chamber by high pressure water connected by the high pressure water inlet-and-outlet, high pressure power of the water pump is achieved. High level water connected with the high pressure water inlet-and-outlet uses water potential energy as a power source and the use ofelectric energy is avoided so that energy is more saved. Water is used as the power source. The plunger type cylinder for water pumping is free in pollution, low in cost and more environment-friendly.Reciprocating movement of the plunger piston is controlled to realize power pushing of the water suction pump and high pressure water is obtained.
