The crusher is hardly deformed, high in safety and low in cost, spare parts of the gearbox are reduced, the using state of the crusher can be monitored in real time, and special casting equipment is not needed.

The invention discloses a video surveillance control system based on a TV set-top box camera, which includes a camera device, a set-top box device and an intelligent terminal; the camera device includes a camera, a data processing module, a data communication module, a data storage module, and a first temperature detection module , a second temperature detection module, a camera angle detection module, a camera lens detection module, a camera humidity detection module, etc. The present invention can realize the remote video monitoring and control process through the cooperative use of the camera device, the set-top box device and the intelligent terminal; through the real-time monitoring of the temperature of the internal circuit chip of the camera and the coordinated use of temperature adjustment, the temperature of the internal circuit chip of the camera can be controlled at Within the safe threshold range, avoid situations such as failure of video image acquisition or even chip damage due to excessive temperature.

The invention relates to a concrete composition and a regeneration technology and additive thereof. The composition comprises an A component, a B component and a C component; the A component comprisessand and gravel, the B component comprises binding agent, diluent, coal ash, mineral admixture and anti-corrosion admixture, and the C component comprises EVA shrinkage balls, talcum powder and quicklime. The EVA shrinkage balls of the C component are added to the concrete, and EVA is a substance which can generate volume shrinkage when being heated or cooled. According to the technical scheme, the EVA shrinkage balls which are shrunk after being heated are adopted, the EVA shrinkage balls are hollow balls and are mixed into the concrete, when the concrete needs to be disassembled, the concrete road surface is subjected to heat pretreatment, the EVA shrinkage balls which are mixed into the concrete road surface are heated, the volumes of the EVA shrinkage balls are decreased, and accordingly a cavity is formed in the portion which is filled with the EVA shrinkage balls in advance; under the situation, when the concrete is hammered, the cavity is easily damaged due to a thin structure,and the concrete composition helps to hammer concrete into small concrete blocks which are used for regeneration concrete aggregate particles.
