The invention discloses a modular waterproof wallboard for decoration, and relates to the technical field of decoration wallboards. The modular waterproof wallboard comprises a wallboard and a mounting plate, wherein the mounting plate is installed on one surface of the wallboard, a groove is formed in one surface of the wallboard, a guide plate is installed on one surface of the wallboard, the guide plate is matched with the groove, a roller shaft is connected to one surface of the guide plate, the side surface of the roller shaft is connected with the wallboard, a clamping groove is formed in one surface of the groove, protective plates are respectively installed on two opposite side surfaces of the wallboard, a connecting cavity is connected to one surface of each protective plate, onesurface of each connecting cavity is connected with the wallboard, a fixed groove is formed in one surface of the wallboard, the mounting plate is matched with the fixed groove in position, a supportcolumn is connected to one surface of the mounting plate, and one end of the support column is connected with the fixed groove. According to the modular waterproof wallboard, waterproof flow guiding is performed through the guide plate, the angle of the guide plate can be adjusted, the guide efficiency can be controlled, and a guide groove is further formed in the back surface of the wallboard, sothat accumulated water can be directly drained, and the waterproof use efficiency is high.

The invention discloses a cage trolley which comprises a cage body, a foldable supporting partition plate is movably arranged in the cage body, ventilation meshes are formed in the supporting partition plate, sliding parts are arranged on the two sides of the supporting partition plate, limiting sliding grooves matched with the sliding parts are formed in the inner wall of the cage body, and the length direction of the limiting sliding grooves is perpendicular to the height direction of the cage body; when the supporting partition plate is folded, the inner cavity of the cage body is provided with a storage cavity; and when the supporting partition plate is unfolded, the inner cavity of the cage body is divided into two storage cavities by the supporting partition plate. The two storage cavities can store goods, the goods in the lower-layer storage cavity are supported by the bottom of the cage body, the goods in the upper-layer storage cavity are supported by the supporting partition plate, the goods in the lower-layer storage cavity do not need to bear the weight of the goods in the upper-layer storage cavity, and the goods in the lower-layer storage cavity can be effectively prevented from being pressed and damaged in the loading, unloading and transporting processes.

The invention provides a damaged point detection device for a cable protection round pipe, which belongs to the technical field of detection. The damaged point detection device used for cable protection round pipes includes camera 1, camera 2, moving cylinder 1 and moving cylinder 2. Shaped mounting groove 2, the moving cylinder body 1 is located in the circular mounting groove 2 of the moving cylinder body 2, and the circular mounting groove 1 of the moving cylinder body 1 is provided with leg 1, leg 2 and leg 3, leg 1, leg 2 and leg The three protrude from the opening of the circular mounting groove 1, and the circular mounting groove 2 of the moving cylinder body 2 is provided with four, five and six legs at equal intervals in the inner circumference, and the four legs, five legs and six legs are all Pass through the moving cylinder two. The invention has the advantage of being able to detect the damaged point of the cable protection round pipe.

The invention belongs to the field of filtering devices for probiotics and particularly relates to a filtering device for preparing the probiotics. The filtering device comprises a filter tank, wherein a first rotating shaft coaxial with the filter tank is movably nested in the top of the filter tank, an outer ring of the first rotating shaft is fixedly connected with a pushing mechanism, a pusherplate movably sleeving the outer ring of the first rotating shaft is fixed to the bottom of the pushing mechanism, a fixed sleeve movably sleeving the outer ring of the first rotating shaft is arranged below the pusher plate, a first fixed plate of an annular structure fixed to the internal wall of the filter tank slidably sleeves an outer ring of the bottom of the fixed sleeve, an outer ring ofthe fixed sleeve is fixedly connected with a first retaining collar located above the first fixed plate, and second fixed plates which are of arrayed distribution along a central axis of the first retaining collar are fixed to an outer ring of the first retaining collar. According to the filtering device for preparing the probiotics, the filtering and concentrating efficiency is increased, the service life of an osmotic membrane is prolonged, the economic loss is lowered, and meanwhile, the labor intensity of working personnel is also lowered.
