The utility model discloses a supporting device for anti-corrosion horizontal coating of an arch rib, and belongs to the field of coating processing of arch ribs. Comprising a supporting column, an upper plate body, a lower plate body and an elastic cushion, the supporting column is cylindrical, the upper plate body is horizontally arranged at the upper end of the supporting column, the lower plate body is horizontally arranged on the lower end face of the supporting column, and the elastic cushion is arranged on the upper end face of the upper plate body. The device is moved to a specific position and placed according to the horizontal position of the arch rib, the arch rib is erected on the device in a suspended mode, and then spraying operation can be started. The technical problems that a vertical spraying construction mode is adopted in traditional arch rib anti-corrosion coating, for arch ribs with the large radial height, the height of a spraying plant needs to be increased, meanwhile, a higher scaffold needs to be erected, and the project cost and danger in the construction process are greatly increased are solved.

This utility model belongs to the technical field of poultry farming equipment, specifically a disinfection device for chicken coops, including an outer cover, a water pump, water pipe A, water pipe B, a first nozzle, and a second nozzle. An isolation plate is fixedly connected inside the outer cover, and a water pump is fixedly connected to the surface of the isolation plate. The end of water pipe A passes through the isolation plate and is fixedly connected to the water pump input end. One end of water pipe B is fixedly connected to the water pump output end, and a lifting device is installed at the other end of water pipe B. A stirring device is installed below the isolation plate. A hopper is fixedly connected to the side wall of the outer cover for easy addition of disinfectant. The lifting device allows for handling chicken cages of different heights. The first and second nozzles ensure more even coverage of the disinfectant spray, and the stirring device ensures more uniform mixing and higher concentration of the disinfectant, resulting in better disinfection. This solves the problems of relying on manual disinfection in chicken coops, which involves long working hours, high labor intensity, and reduced spray strength and efficiency due to personnel fatigue.

This utility model discloses a grid structure for dredging and maintenance of an inverted siphon culvert. It includes a vertical shaft with a horizontal grid at the shaft opening. A debris-blocking opening is formed on the side wall of the shaft, and a debris-blocking grid is vertically installed inside the debris-blocking opening. The horizontal grid is composed of multiple sub-grid components to cover the shaft opening. A support beam is provided inside the shaft opening to support the sub-grid components. The length direction of the support beam is parallel to the length direction of the debris-blocking opening. The multiple sub-grid components are divided into a first sub-grid and a second sub-grid. The opposite ends of the first sub-grid are respectively installed on support steps opposite each other at the shaft opening. One end of the second sub-grid is installed on a support step on one side of the shaft opening, and its opposite end extends above the debris-blocking opening and is supported by the debris-blocking grid. This utility model can disassemble the horizontal grid into multiple sub-grids to reduce the weight of a single piece, and can also provide a central support beam to reduce the rigidity requirements of the sub-grids, thereby reducing thickness and weight, and facilitating manual handling.

The utility model discloses a road surface gravel cleaning device, and relates to the technical field of road and bridge maintenance. The road surface gravel cleaning device comprises a collecting vehicle, a push rod is fixedly connected to the outer wall of one side of the collecting vehicle, moving wheels are fixedly connected to the outer wall of the bottom of the collecting vehicle, a shovel plate is fixedly connected to the bottom of the inner wall of the collecting vehicle, and a mounting plate is fixedly connected to the outer wall of one side of the collecting vehicle; a first sweeping mechanism and a second sweeping mechanism are arranged between the outer walls of the two mounting plates. Gravel can be effectively shoveled through the shoveling plate, the gravels on the road surface can be efficiently collected into the collecting vehicle in cooperation with the first sweeping mechanism and the second sweeping mechanism, the crushing rollers are arranged in the crushing box and can efficiently crush the gravels, the gravels can be crushed into finer particles through meshing of the two crushing rollers, and the gravels can be effectively collected through the shoveling plate. And through the arrangement of the crushing device, the collection amount of the collection box is increased, frequent cleaning and replacement of the collection box are avoided, and the working efficiency is improved.
