This utility model provides a rainwater harvesting and utilization device, including a collection cylinder with a water storage chamber inside for collecting water. A circular opening is located at the center of the collection cylinder. A rain-blocking plate is located at the upper end of the collection cylinder. A connecting rod, extending into the central opening of the collection cylinder, is located below the rain-blocking plate. A spiral frame is located at the lower end of the connecting rod, and a filter screen is laid on top of the spiral frame. The outer surface of the spiral frame is perforated, and a water inlet groove is formed within the opening of the collection cylinder, corresponding to the perforation on the outer surface of the spiral frame. The rain-blocking plate of this utility model can guide oblique rainwater from any direction, preventing rainwater splashing and loss due to wind. Furthermore, the filter screen and spiral frame are both spiral structures; the spiral shape of the filter screen guides intercepted impurities to automatically slide down the spiral path and ultimately fall into the trash can below, preventing impurities from accumulating and clogging the filter screen.

A secondary drainage system for draining water seeping from tile grout in bathrooms addresses the technical problem mentioned in the background art: secondary drainage relies on secondary leveling, requiring a drainage slope of at least 2° with the ground as the base layer and the secondary drain outlet as the lowest point. Therefore, without leveling the ground, water seeping into the tile grout cannot be effectively drained. The system includes a main drain pipe with an inlet and an outlet at both ends. Four branch pipes are connected to the main drain pipe, each connected to the side wall of the main drain pipe and evenly distributed circumferentially. Each branch pipe has a connecting pipe with several through holes for collecting water from the grout between adjacent tiles and discharging it into the branch pipe. Adjacent connecting pipes have connecting components, including a first connector, a second connector, a first elbow, a second elbow, and a plug.

The utility model relates to the technical field of printing and dyeing, in particular to cloth printing and dyeing equipment uniform in printing and dyeing, which comprises a dye box, the inner wall of the dye box is rotatably connected with a material guide roller, the surface of the dye box is provided with a pad printing device, the pad printing device comprises four sliding frames, and the sliding frames slide relative to the edge of the upper end of the dye box. The four sliding frames are arranged in pairs, rollers are rotationally connected to the sides, close to each other, of the sliding frames in each group, a positioning roller is rotationally connected to the inner wall of the dye box, the rollers and the positioning roller are located at the same height, and a protruding block is fixedly connected to one side of each sliding frame. Parts such as the air cylinder, the push plate, the pull rope, the protruding block and the extension spring work cooperatively, the distance between the two rollers can be accurately controlled, the device can easily meet the printing and dyeing requirements of cloth with different thicknesses, complex device replacement or adjustment is not needed, the application range of the device is remarkably widened, and the universality of the device is improved.

The utility model relates to the technical field of double-side air outlet coolers, in particular to a double-side air outlet cooler with a filtering function, which comprises an air cooler body, two mesh enclosures are fixedly mounted on two sides of the air cooler body, and a filtering structure is arranged on the inner side of the air cooler body. The filtering structure comprises two storage grooves formed in the lower surface of the air cooler body, a filtering frame is arranged on the inner sides of the storage grooves, two rotating shafts are rotatably connected to the interior of the filtering frame, a plurality of arc-shaped strips of arc-shaped structures are fixedly connected to the side walls of the rotating shafts, and a plurality of columns of fixing strips are fixedly connected to the inner side of the filtering frame. The fixing strips and the arc-shaped strips are arranged in a staggered mode, and the bottom wall of the storage groove is fixedly connected with a limiting strip. According to the utility model, by arranging the filtering structure with the crushing structure, the utilization rate of activated carbon particles is improved, and the purification and filtering efficiency of blown cold air is improved to a certain extent.

The invention relates to the technical field of aluminum alloy machining, in particular to high-corrosion-resistance colorful aluminum alloy decorating part forming machining equipment which comprises a conveying system, an aluminum alloy plate and a mold used in cooperation with the aluminum alloy plate, and further comprises four clamping plates, a first clamping plate, a second clamping plate, a third clamping plate and a fourth clamping plate, according to the high-corrosion-resistance colorful aluminum alloy decorating part forming machining equipment, the two sets of clamping plates are matched with the four centering plates, the centering plates are driven by the correcting part to conduct synchronous extrusion and correction, it is ensured that the aluminum alloy plate is accurately aligned with the mold, and the machining efficiency is improved. Therefore, when the end of the aluminum alloy plate is clamped subsequently, the end of the aluminum alloy plate is filled through the mold, the situation that the plate is seriously deformed or damaged due to the fact that the clamping force of the clamping plate is too large is avoided, meanwhile, rapid mold replacement is achieved through an inserting rod and inserting groove matching structure of the assembling and disassembling piece, and the equipment maintenance and production switching efficiency is remarkably improved; and the downtime is reduced.
