In a spectrophotometer for measuring transmitted light of a trace liquid sample, four sample holding portions (12) are provided on a disklike sample plate (11) while spaced apart by 90 DEG , and then the sample plate (11) is rotary driven to move each sample holding portion (12) sequentially to a sample supply position (U1), a measuring position (U2), a wiping position (U3) and a waiting position (U4). A trace of liquid sample is dripped into a groove in the sample holding portion (12) at the sample supply position (U1), a window plate (22) is lowered to above that groove at the measuring position (U2) and transmitted light is measured after the optical path length is determined, and the liquid sample is absorbed and removed through contact with a cleaning pad (26) while the sample holding portion (12) moves from the measuring position (U2) to the waiting position (U4).; Liquid sample adhering to the window plate (22) is also wiped off by other pad. Since wiping work of measured sample is automated, throughput of measurement can be enhanced.

The invention relates to a special and automatic window wiping device for an indoor building. The device comprises a detachable fixing device, wherein the detachable fixing device has the function of facilitating disassembling and assembling; when the device is damaged and needs to be maintained, the device can be disassembled manually by means of the detachable fixing device, what is required is to take off a damaged part for maintenance, and operation is simple and convenient; a directional conversion device is mounted at the upper end of the detachable fixing device and has the function of adjusting a wiping angle, so that the window wiping device can be applied to overhead glass at different angles and has a wide application range; a window wiping manipulator is mounted on the upper end surface of the directional conversion device and has an automatic wiping function. The detachable fixing device comprises a fixing disk, and four positioning shafts II are uniformly welded in the middle of the upper end surface of the fixing disk in the direction of the axis. The special and automatic window wiping device has an automatic wiping function on the overhead glass and provides a new approach for full-automatic wiping of the overhead glass.

The invention provides a wipe control system and method for a block region of a windshield. The system comprises an image shooting device, a block region identification module and a windshield wiper controller, wherein the image shooting device is aligned to the windshield and shoots images in real time, so that original images at least containing a windshield wiper region are continually obtained; the block region identification module receives the original images in real time, identifies the block region in the original images and locates the coordinate and the region range of the block region in the original images; a plurality of branch wipe regions used for dividing the windshield wiper region are arranged in the block region identification module in advance, the corresponding branchwipe regions is selected according to the coordinate and the region range so as to generate a first block region characteristic value and generate a first branch wipe instruction; the windshield wipercontroller determines the upper and lower limit range of a windshield wiper according to the first block region characteristic value, adjusts the upper and lower limit range of a windshield wiper according to the change of the first block region characteristic value, and at least responds to the first branch wipe instruction to control the windshield wiper to wipe repeatedly in the upper and lower limit range of the windshield wiper. By means of the wipe control system, it is achieved that obstructions are quickly wiped, so that it is avoided that the obstructions have an impact on driving safety.

The invention discloses a primary education teaching auxiliary device, and relates to the technical field of teaching equipment. The primary education teaching auxiliary device comprises a blackboardbody and a dust receiving box; sliding plates are arranged on the two sides of the blackboard body in a penetrating mode correspondingly, and the sides, extending to inner cavities of the sliding plates, of the blackboard body are slidably connected with one sides of the inner cavities of the sliding plates; the surface of the blackboard body is fixedly connected with a fixing box; and a tooth plate is fixedly connected between the top and the bottom of an inner cavity of the fixing box. According to the primary education teaching auxiliary device and an operating process thereof, dust on theblackboard body can be wiped well, the overall wiping speed is greatly increased, the labor intensity of a teacher is lowered while the time of the teacher is saved, and the blackboard body is wiped in an all-round mode; and the dust after the blackboard body is wiped can be collected well, the situation that the dust stays in a space during wiping is avoided, the harm of the dust to the teacher is relieved, and the overall height of the blackboard body can be adjusted.
