During the travel of a vehicle, the oil level of lubricating oil is lowered due to the suction by at least a first oil pump and the scraping-up by the rotation of a differential ring gear and so on. In particular, until the oil level becomes equal to or lower than an upper end of a first partition wall, the oil level is lowered due to both the suction by the first oil pump and the scraping-up by the rotation of the differential ring gear and so on, and therefore, a region, that is immersed in the lubricating oil, of the differential device rapidly becomes smaller. Since a suction port of the first oil pump is disposed in a second oil storage portion, the oil level in the second oil storage portion during the travel of the vehicle can be adjusted independently of that in a first oil storage portion.

The invention discloses a physical lung-type oxygenation organic reef and its application method, wherein the physical lung-type oxygenation organic reef is fixed in water body. The invention is characterized in that the physical lung-type oxygenation organic reef is made from a high-strength thin film material; a large opening air bag is fixed underwater with the opening of the air bag downward and the bottom of the air bag keeps a certain distance from the water-bed; the top of the air bag is equipped with a connecting pipe, which leads directly to the water surface and is provided with a one-way check valve, and simultaneously the outer wall of the air bag is connected with a lot of hydrophilic fibers or ropes; a gas which is filled into the connecting pipe is reserved inside the upper portion of the air bag and directly contacts with the water surface under the lower portion of the air bag to form the physical lung-type oxygenation organic reef.

A composite sound insulation wallboard for dividing a ship cabin comprises a lower panel. A rock wool layer is arranged on the upper side of the lower panel, and a micro-perforated plate is arranged on the upper side of the rock wool layer at an interval, a glass wool layer is installed on the upper side of the micro-perforated plate, an upper panel is installed on the top surface of the glass wool layer and is parallel to the lower panel, side panels are welded to the two sides of the upper panel and the lower panel respectively, the two sides of the rock wool layer and the glass wool layer are bonded to the side panels, and the two sides of the micro-perforated plate are welded to the side panels; the gap between the upper side of the rock wool layer and the micro-perforated plate formsan air layer. Based on the transmission and reflection mechanism in airborne sound wave propagation, the structural form that materials on the two sides are different in density and thickness is utilized to realize impedance mismatch, the structural shape of the low-density glass wool is maintained through the micro-perforated plate, the sound absorption effect at a low frequency of 1000 Hz or below is improved, and the total sound insulation of the structure is improved finally.

The invention discloses a heat insulation coating, and belongs to the field of building coatings. The heat insulation coating aims at solving the problem that a heat insulation coating in the prior art is thick in coating layer and is unsuitable for a facing layer of a building external wall. The heat insulation coating is characterized by being prepared from low-density hollow glass microspheres,hydrophobic emulsion, a water repellent, nanosilicon dioxide, a foaming agent, an air entraining agent, elastic emulsion, a thickening agent and grapheme. The heat conductivity coefficient of the coating is lowered to 0.030 W / (m K), the coating can be used in cooperation with primer and a reflective heat insulation surface paint layer, a coating with the low thickness is scraped in batch, and theexcellent heat insulation effect can be obtained. The invention correspondingly discloses a preparing method for the heat insulation coating, the heat insulation coating prepared with the method is suitable for scraping in batch or spraying or napping construction, and has the advantages of being high in bonding strength, good in waterproof performance and excellent in anti-cracking and heat insulation performance. The invention also discloses a heat insulation system with the heat insulation coating, and the heat insulation system has the advantages that the heat insulation system can be used for a building external wall / internal wall, the heat insulation effect is good, and energy saving and environmental protection effects are achieved.
