The invention discloses a compressed air energy storage system using carbon dioxide as a working medium. The system utilizes the supercritical characteristic of carbon dioxide and the state change characteristic of the carbon dioxide near the critical point, and the assistance by the conditions of outside environments (such as underground and seabed cavities) is not needed, so the switching of the energy storage system among constant-pressure energy storage, constant-pressure energy releasing, constant-capacity energy storage and constant-capacity energy releasing is realized, and the different types of power storage and releasing can be realized. The system utilizes the characteristic of the carbon diode which is converted from the gas state into the supercritical or liquid state, so the carbon dioxide is stored, and compared with the gas storage, the complicated degree and design difficulty of the system are effectively reduced, and the cost of the energy storage system is reduced. Meanwhile, the double-storage device method is adopted, the switching of the system between energy storage and energy releasing is flexibly completed without utilizing the assistance by the outside environments (such as underground and seabed cavities), the energy storage and energy releasing characteristics of the system are changed by controlling the carbon dioxide storage / releasing method, and the flexibility of the system is enhanced. The system can be used together with the renewable energy sources, such as solar energy and wind energy, so the generation of other pollutants is avoided, and the environment-friendly characteristic is good.

The invention discloses a rotation-folding-type environment-friendly recyclable fruit growth protection device which is characterized in comprising at least six arc supporting bars, two arc sides and an umbrella-shaped top. An annular slide rail is arranged under the umbrella-shaped top. The upper parts of the arc supporting bars and the arc sides are connected and mated on the annular slide rail. The lower parts of the arc supporting bars and the arc sides are hinged together. The slidable arc sides can be closed and can be snapped through snap buckles. Rubber sealing strips are provided on the contact surfaces of the two arc sides. The arc supporting bars are distributed with equal spaces along the annular slide rail. A foldable film connected with the arc supporting bars and the arc sides is arranged around the arc supporting bars and the arc sides, and covers the arc supporting bars and the arc sides, such that a spherical cavity is formed. A fruit stalk gap is arranged on the edge of the umbrella-shaped top. The assembly process of the device is simple and fast. The device is not prone to deformation and damage, and can be recycled repeatedly. Therefore, an average cost is reduced, and energy consumption is reduced. The device has better environment friendliness.

The invention discloses a tapered cylinder type environmental friendly repeatedly-used fruit protector. The tapered cylinder type environmental friendly repeatedly-used fruit protector is characterized by comprising a circular top cover and a tapered cylinder, the big end of the tapered cylinder is an up opening, the small end of the tapered cylinder is provided with a downward seal bottom, the edge of cylindrical wall of the axial section of the tapered cylinder is a curve, a plurality of tapered cylinders can be overlapped together, the edge of the top cover is provided with a lower reversed-bended edge, a connecting ring is connected in the lower reversed-bended edge, the lower portion of the connecting ring is connected with the opening big end of the tapered cylinder, the periphery of the circular top cover is provided with a stem hole extending to the center portion of the circular top cover. The tapered cylinder type environmental friendly repeatedly-used fruit protector is easy and quick to mount, hard to deform and damage, the connecting ring can be taken out from the top cover after a ripe fruit is picked, a plurality of tapered cylinders can be overlapped together, so the size of the tapered cylinders is small and convenient to transport, the fruit protector can be used again in the nest growing period of a fruit tree, so the fruit protector can be repeatedly used for many times, the average cost is reduced, and the energy consumption is reduced at the same time, the fruit protector can be recycled and reused after repeatedly used for many times, a problem that a conventional fruit bag cannot be reused can be solved, and the fruit sleeve is better in environmental protection.
