There are air outlets and several air outlets connected with the air extraction cavity, among which: the air outlet is located in the center of the top plate of the operation box, and a fairing is arranged above it; the bottom plate of the operation box is provided with a main shaft, which is movably supported on the base, and Connected to the rotary drive. The invention is mainly used in the cooling device for cooling the casting and welding mold in the production process of the accumulator.

The invention discloses a touch control method, system and touch device based on electronic whiteboard equipment. The touch control method includes detecting whether there is a touch pen in the touch area of ​​the touch screen for touch operation; judging whether the touch width of the touch pen satisfies the first predetermined Setting conditions; if the touch width of the touch pen meets the first preset condition, record the touch track of the touch pen, and send the touch data to the operating system; otherwise, judge whether the touch width of the touch pen meets the second preset condition; if If the touch width of the touch pen satisfies the second preset condition, it is judged whether the touch operation of the touch pen satisfies the third preset condition; if the touch operation of the touch pen meets the third preset condition, the Display virtual keys. Through the touch method, virtual keys can be called out conveniently, avoiding the user from walking back and forth in front of the electronic whiteboard, and at the same time avoiding misoperation of calling out the virtual keys.

The invention discloses a tomato picking device and a method. The tomato picking device comprises a driving device and a trailer, the driving device drives the trailer to walk between two ridges of tomato plants, and a tray storage mechanism, a tray driving device and a weighing device are arranged on the trailer; the tray storage device comprises two vertical plates which are vertically and fixedly connected to the trailer, the two vertical plates are provided with two tray falling mechanisms respectively, an opening is formed in the lower end of each vertical plate, and multiple trays are stacked between the two vertical plates; the vertical plates are provided with driving parts, the driving parts comprise multiple first air cylinders and multiple guide rails, the first air cylinders and the guide rails are fixedly connected to the end face of the trailer, slide blocks are arranged on all the guide rails and jointly fixedly connected to one frame, the frame is internally provided with multiple first driving motors and multiple friction wheels, the first driving motors are in transmission connection with the friction wheels, and the first air cylinders drive the frame to move onthe guide rails. By means of the tomato picking device and the method, tomatoes can be picked, weighed and subpackaged simultaneously, the picking efficiency is improved while the labor intensity of workers is reduced, and the time for putting the tomatoes into the market is shortened.

The invention discloses a mounting and construction method of U-shaped tunnel pipelines. The method comprises the following steps of: mounting pipelines of a left inclined shaft section firstly and meanwhile, carrying out pipeline transportation and distribution of a level section; after the pipeline transportation and distribution of the level section is finished, mounting pipelines of a right inclined shaft section; and finally, connecting the heads on the level section to run through, wherein the pipeline mounting of the inclined shaft sections comprises the following steps of: laying a light rail through the whole course at the bottom of the tunnel; then embedding a ground anchor, fixing a winding machine and beginning to excavate a working pit; mounting a hoop and a sled on a pipeline; connecting a pulley block with the ground anchor, the pipeline, the loop and the winding machine; ensuring that the pipeline downwards slides along the light rail through the sled until the upper port of the pipeline arrives at the working pit; then continuing to mount another pipeline; and repeating in such a way until the inclined shaft pipelines and the level pipelines are butt jointed. In the construction method, the operations of welding, flaw detecting and joint repairing aiming at the inclined shaft pipelines are all finished outside the port of the tunnel, thereby avoiding the construction in the tunnel, improving the construction safety, reducing the labor intensity and being beneficial to improving the welding quality, shortening the construction period and saving the construction cost.

The invention relates to the technical field of steel processing, in particular to an integrated machine for automatic surface descaling treatment of H-shaped steel, comprising a liquid storage tank and a plurality of ultrasonic generators installed at the bottom of the liquid storage tank, the liquid storage tank is away from the drainage A discharge port is opened at the lower part of one side of the pipe, and a collection box for collecting sediment is fixedly connected with the liquid storage tank on the outside of the discharge port, and a movable bottom plate is installed at the inner bottom of the liquid storage tank. A slot is installed on the side of the bottom of the liquid tank close to the drain pipe, a plug-in board is installed in the slot, two first magnet blocks are installed on the upper surface of the plug-in board, and two first magnet blocks are installed on the lower surface of the movable bottom plate Compared with the prior art, the second magnet block corresponding to and repelling the first magnet block has the following beneficial effects: realizing the accumulation of sediment at one end of the liquid storage tank, avoiding personnel walking back and forth, and reducing labor intensity , improve the efficiency of cleaning sediments.

The invention discloses a winding and positioning tool for preimpregnated glass roving tape, which comprises a wall plate (2) erected on a base (1). ) and the wall plate (2) keep a rolling fit, the lower part is provided with a screw (7), one end of the two pressure plates (5, 6) is installed on the shoulder screw (3), and the other end is installed on the handle (4), to be wound The parts of the pre-impregnated glass roving tape pass through the shoulder screw (3) and the handle (4), and are fixedly placed between the two pressing plates (5, 6), and are held by the two pressing plates (5, 6). Clamping, two opposite pressure plates (12, 13) are installed on the screw rod (7), a limit block (9) is arranged between the wall plate (2) and the pressure plate, and the pre-impregnated glass roving tape (14) The charging tray passes the screw rod (7) and is installed between the two pressure plates (12,13). The tooling of the present invention is rotated and wound in the vertical direction, which can ensure uniform force application and no deviation in the direction. The width of the prepreg glass roving tape during the winding process is uniform and the thickness is consistent; the operation is simple, saving manpower and winding time .
