The utility model discloses cloth dip-dyeing equipment which comprises a dip-dyeing box body, two groups of buffering mechanisms, two groups of driving parts, a middle partition plate, a fixing support and a dip-dyeing assembly, the two groups of buffering mechanisms are respectively arranged in the dip-dyeing box body, the two groups of driving parts are respectively arranged in the dip-dyeing box body, and the middle partition plate is arranged on the fixing support. The output end of the driving component abuts against and is connected with the buffering mechanism, the middle partition plate is arranged in the dip dyeing box body, the two ends of the fixing support are arranged in the middle partition plate and the dip dyeing box body respectively, and the dip dyeing assembly is arranged in the dip dyeing box body and movably arranged on the middle partition plate. Therefore, the cloth sequentially penetrates through the multiple open grooves and the open grooves of the middle partition plate, the cloth is in a regular folding or stacking state in dye liquor under the limiting effect of the guide rollers, the dye liquor permeation area is increased, uneven local dyeing is avoided, pressure dip dyeing is conducted under stress, and the dip dyeing speed is increased.

This utility model discloses a water-saving irrigation device for rice cultivation, which includes a main water pipe (1), a pressurized water pump (2), multiple branch water pipes (3), and a controller (4). Each branch water pipe (3) has a water outlet pipe (5) installed at its end, which is vertically positioned in the rice field. Each water outlet pipe (5) has three water injection nozzles installed on it. Each water injection nozzle has a solenoid valve (6) installed on it. Above each water injection nozzle, there is an arc-shaped baffle (7) fixed on the water outlet pipe (5). Each baffle (7) has a soil moisture sensor (8) installed on its top surface. Each solenoid valve (6) and soil moisture sensor (8) is electrically connected to the controller (4). This utility model not only improves water utilization efficiency but also has the advantages of good irrigation effect, good water-saving effect, convenient use, long service life, convenient maintenance, high irrigation rate, simple structure, and high structural stability.

This invention relates to an anti-backflow composite plastic drainage board and its construction method. The drainage board includes a core board and a filter membrane. The core board includes a main core board and a secondary core board. The main core board is composed of wing plates and a web plate. Some wing plates are continuously thickened to form longitudinal reinforcing ribs, and the web plate is thickened to form transverse connecting ribs. The longitudinal reinforcing ribs and transverse connecting ribs intersect to form a reinforced structure, improving the bending and shear stiffness of the drainage board. The secondary core board is a protruding structure extending outward from the side of the main core board. When the steel sleeve is pulled up, it is embedded in the soil to form an anchor, preventing backflow. At the same time, the secondary core board also increases the permeable area. The bottom end of the main core board is provided with a conical protective sleeve and a clamping device to seal the end of the drainage channel and prevent mud sludge blockage. This invention solves the problems of insufficient stiffness, excessive backflow, and sludge blockage failure of drainage boards from the perspective of the drainage board structure. It enables the drainage board to have high stiffness, anti-backflow, and anti-sludge performance without the need for external accessories, and is suitable for various soft soil foundation treatment conditions.

Embodiments of the present application disclose a display panel and a display device, the display panel comprising a first region, a second region and an opening, the opening being filled with a light shielding material. The opening between the first sub-region and the first region is a first opening, the first opening extending along a first direction, the width of the first opening in a direction perpendicular to the first direction being D1, and the depth of the first opening in a thickness direction of the display panel being H1. The opening located in the second sub-region is a second opening, the second opening extending along a second direction, the width of the second opening in a direction perpendicular to the second direction being D2, and the depth of the second opening in the thickness direction of the display panel being H2, wherein D1>D2, and / or H1>H2. The first opening and the second opening filled with the light shielding material respectively block the influence of light between the first sub-region and the first region and between the second sub-region and the first sub-region, thereby improving the display effect, and by setting D1>D2 and / or H1>H2, the transmittance of the display panel is improved.
