The invention belongs to the technical field of medical experiments and provides a multi-platform water environment sleep deprivation water tank and system for animals. Platforms are arranged in the bottom of the sleep deprivation water tank. The sleep deprivation system includes a rack, the sleep deprivation water tank, a water inlet / outlet device and a control device controlling experiment time, sewage disposal and cleaning. By adopting the water tank and the system provided by the invention, influence due to elements such as biological instability and the like in a sleep deprivation experiment is avoided. The experiment result is good in stability and high in repeatability. The device is high in operability, high in space utilization rate and good in application effect.

The invention discloses a vacuum pipe for a solar water heater. The vacuum pipe for the solar water heater comprises an outer glass pipe and a vertical rod, wherein an inner glass pipe is arranged atthe inner side of the outer glass pipe, and a cavity is formed in the inner side of the inner glass pipe; an electrical heating rod is installed in the cavity; water inlet ports are located in the topends of the inner glass pipe and the outer glass pipe, and a water storage chamber is formed between the inner glass pipe and the outer glass pipe; a first cleaning block is arranged in the water storage chamber, and a first magnetic block and first cleaning cotton are fixed to the first cleaning block; a fixed plate is installed on the outer glass pipe, and a slide groove is formed in the surface of the fixed plate; the end of the vertical rod is located in the slide groove; and a second cleaning block is installed on the vertical rod, and a second magnetic block and second cleaning cotton are fixed to the second cleaning block. According to the vacuum pipe for the solar water heater, regular cleaning for the inner wall of the vacuum pipe is facilitated, so that the accumulation of waterscale in the vacuum pipe is effectively prevented; and meanwhile, convenient dust cleaning can be carried out on the outer wall of the vacuum pipe, so that more reasonable design is achieved.

The invention discloses a packaging carton positioning and punching device which comprises a base. Working grooves are formed in the two sides of the top of the base, screws are movably connected to the opposite sides of the bottoms of inner cavities of the working grooves through bearings, driven gears are fixedly connected to the bottoms of the surfaces of the screws, driving gears are engaged to the opposite sides of the driven gears, and rotating rods are fixedly connected to the opposite sides of the driving gears. The base, the working grooves, the screws, the driven gears, the driving gears, the rotating rods, motors, threaded sleeves, sliding grooves, sliding blocks, moving plates, lifting plates, electric telescopic rods, clamping blocks, punching holes, discharging pipes, a dust collecting box, supporting plates, a transverse plate, a hydraulic cylinder, a punching plate and a punching head are matched, so that a packaging carton can be well clamped and positioned through a punching device and then punched, so that the purpose that the punching device has a good positioning effect is achieved, and the working efficiency and practicability of the punching device are greatly improved.

The invention discloses an automatic cleaning device of the surface of a photovoltaic battery panel array. The device comprises a framework, a sliding block, a guide rail, a composite strip-shaped brush, a pressure sensor, a disc brush, a disc brush driving motor, a traction motor and a wire coil; a single chip microcomputer sends a signal to the traction motor, the traction motor drives the wirecoil to rotate, and a steel wire rope on the wire coil is connected with a dust removal mechanism; under the driving of the steel wire rope, the whole device moves on the guide rail, meanwhile, a discdriving motor drives the disc brush to rotate, and the surface of the battery panel is scrubbed so that dust removal can be more thoroughly carried out by the composite strip-shaped brush. Accordingto the device, a timing parameter is changed according to the ash accumulation degree of the solar battery panel and the surrounding environment of a photovoltaic power station, the surface of the battery plate can be automatically cleaned by the device; according to the device, energy consumption is relatively low, the device can replace manual operation to complete dust removal work of a large photovoltaic array; and the device is simple in structure, low in cost and high in stability, and is particularly suitable for the dust removal work of the large photovoltaic power station which is poor in water resources and short in labor force.
