The invention discloses a device for cleaning the surface of a conductor of an electric wire cable. The device comprises a rack, a motor, a bearing seat, a bearing, a driving belt wheel, a driven belt wheel and a triangular belt, wherein the motor and the bearing seat are fixedly arranged on the rack; the bearing is arranged in the bearing seat; the driving belt wheel is fixedly connected with anoutput shaft of the motor; the driven belt wheel is provided with a central hole; and the triangular belt is sleeved on the driving belt wheel and the driven belt wheel. The device is characterized by also comprising a hollow rotary shaft, a disk-like adjustment fixed plate, a brush carrier and a non-metal brush, wherein the hollow rotary shaft is fixedly sleeved in the bearing and the central hole of the driven belt wheel; the disk-like adjustment fixed plate is fixedly connected with one end of the hollow rotary shaft; the brush carrier is connected with the disk-like adjustment fixed platethrough an adjustment bolt; and the non-metal brush is connected with the brush carrier (8). The device can also comprise a supporting limiting mechanism of the conductor of the electric wire cable. The device can be widely applied to the production link of various kinds of electric wire cables and can be flexibly configured on different stations before drawing, pressing and stranding of a conducting wire and insulation extrusion in the manufacturing process of the electric wire cables; and the surface of the conductor can be efficiently, conveniently and quickly cleaned.

The invention discloses a method and device for clearing internal storage in a mobile terminal. The method includes the steps of receiving an operation command of clearing the internal storage, determining the internal storage clearing range of the mobile terminal in the current operating system environment, determining clearable contents in a current operating system according to the clearing range, when it is determined that the clearing range is a conventional clearing range, enabling being-operating processes, except for system core processes and protected processes, of the operating system to be determined to be the clearable contents in the current operating system, enabling the protected processes to be determined according to a pre-built protected process white list, and releasing internal storage space occupied by the clearable contents by stopping the processes corresponding to the clearable contents. According to the method and device for clearing the internal storage in the mobile terminal, efficient and convenient internal storage clearing can be achieved.

The invention provides a sand suction air-lift device. The sand suction air-lift device comprises a sand suction tube, wherein the upper end of the sand suction tube extends into a sand discharging chamber; the upper portion of an extending end of the sand suction tube in the sand discharging chamber is transversely provided with a baffle which stops muddy sand from entering a fan; and the fan is arranged above the baffle. When silted river sand is required to be cleaned, the lower end of the sand suction tube extends in the silted river sand, the fan is started, the air pressure in the sand discharging chamber and the air pressure in the sand suction tube are reduced, the silted river which is in contact with the lower portion of the sand suction tube is sucked in the sand suction tube, after being sucked in the sand discharging chamber, the river sand in the sand suction tube impacts the baffle, then is discharged out of the sand discharging chamber and is collected, the silted river sand is cleaned, the height of the sand suction tube can be adjusted according to operation height, the inner air pressure of the sand suction air-lift device is reduced with the aid of the fan, working requirements can be met, and the baffle can effectively prevent the river sand from entering the fan. By the sand suction air-lift device, the silted river sand can be cleaned conveniently and efficiently.

The invention discloses a small dam opening desilting machine. The small dam opening desilting machine includes a truss trolley, a main working mechanism and two tracks. The truss trolley is composedof a sludge collection box, a truss, four wheels, two wheel driving motors, garbage collection nets and garbage collection net swing driving motor. The main working mechanism is composed of an overhead crane, sludge mixing devices, sludge suction mechanisms and a telescopic pipe telescopic control mechanism. The truss trolley can move freely on the tracks, and the main working mechanism can move freely on a truss guide rail driven by the moving overhead crane. By arranging the truss trolley capable of moving freely, the moving overhead crane, a garbage collection device capable of swing freely, the sludge mixing devices with adjustable up and down positions, the telescopic pipe telescopic control mechanism and the high-efficiency sludge suction mechanisms, the purpose of efficient and convenient cleaning of water surface garbage and underwater sludge at an opening of a small dam is realized.

The invention discloses a particular structure of a double-side single-layer sewage treatment apparatus. The technical scheme includes that the double-side single-layer sewage treatment apparatus withthe integral structure comprises a lower treatment tank, a limit plate, a support plate and two upper treatment tank; double sides of the double-side single-layer sewage treatment apparatus refer tothe fact that 'the two upper treatment tanks are symmetrically positioned on the top of the lower treatment tank'; a single layer of the double-side single-layer sewage treatment apparatus refers to the fact that 'only a layer of filter screen is arranged in each upper treatment tank'. According to the technical scheme, the particular structure of the double-side single-layer sewage treatment apparatus has the advantages that angles of the filter screens can be adjusted by the aid of dispatching ropes on the premise that the filter screens are not detached; residues which remain on the surfaces of the filter screens can be scraped by the aid of inner push plates, and the filter screens can be ultimately efficiently, conveniently and quickly cleared up under scouring effects of water flow.

The invention discloses an anti-corrosion intelligent water supply system. An inner shell of the water tank is welded on the inner side of the outer shell of the water tank. An observation port is arranged in the middle of the top end of the outer shell of the water tank. Bolts are fixedly connected with a support guide rod, and the outer middle part of the support guide rod is movably connected with a connecting slider. The inclined frame, the top of the inclined frame is fixedly connected with a rubber scraper by screws, the present invention effectively reduces the corrosion rate of the water storage tank through the action of the rubber scraper and the arc scraper, and prolongs the use of the inner shell of the water tank At the same time, it prevents germs from breeding and multiplying inside the water storage tank, improves the cleanliness inside the water storage tank, prevents tap water from forming secondary pollution in the water storage tank, and optimizes the use process of water supply equipment.
