This application relates to a rainwater source adjustment and storage system for a sponge city, which includes a water storage tank and a desilting mechanism. There are water inlet holes on the side wall of the water storage tank. The water storage tank includes a pool body and a base located under the pool body , the tank body and the base are integrally arranged, the bottom of the reservoir is set in the shape of a cone and the bottom end is open, the upper surface of the base has an accommodation cavity, the accommodation cavity communicates with the inside of the pool body, the desilting mechanism includes desilting components, The lifting component for driving the desilting component to lift up and down, and the turning component for driving the desilting component to turn over. The desilting component includes a mud box placed in the accommodation chamber for sedimentation. The mud box opens vertically upwards, and the storage The side wall of the pool is provided with a discharge slideway for the sediment to slide out, and the end of the discharge slideway extends into the reservoir. The application has the advantages of being able to remove the mud and sand in the reservoir, and reducing the possibility of blockage caused by a large amount of mud and sand accumulation.

The invention discloses an arc type overflow dam capable of automatically washing away sand and reducing siltation and a running method of the arc type overflow dam. The arc type overflow dam capable of automatically washing away sand and reducing siltation comprises a dam body, a flow releasing and sand discharging hole, gate slots, gates, a guide wall and a protection bank. The arc type overflow dam capable of automatically washing away sand and reducing siltation is characterized in that the dam body is of an arc reinforced concrete structure; the flow releasing and sand discharging hole is formed in the right side of the dam body; the gate slots are formed in the inner walls of the two sides of the flow releasing and sand discharging hole; the gates are manual steel gates and are installed on the gate slots; the guide wall is of an anti-scouring reinforced concrete structure and is arranged on the upstream right bank; and the protection bank is of an anti-scouring reinforced concrete structure and is arranged on the downstream left bank. In the water season, the steel gates are opened, bend transverse ring flow formed by the arc dam body is utilized for automatically conducting flow releasing and sand washing; and in the dry season, the steel gates are closed, the water level is elevated, and water is stored. Compared with traditional mountainous area overflow dams, the arc type overflow dam has the beneficial effects that the form is decent and attractive, little mud and little sand are deposited in front of the dam, the siltation reducing cost is low, and the comprehensive benefits of the project are more obvious.

The invention provides a drilling fluid mud negative pressure screening system, which relates to the technical field of drilling fluid treatment, which includes an annular filter belt and a first drive mechanism that drives the filter belt to rotate and vibrate in the circumferential direction. The tensioning mechanism of the filter part of the filter belt is tightened. The upper part of the filter part is provided with a liquid inlet mechanism, and the liquid inlet mechanism is provided with an anti-flush mechanism. The separation device, the gas-liquid separation device and the negative pressure generating device are connected. The solid-liquid separation device includes a cyclone casing and a rotating impeller with gaps arranged in the cyclone casing. The rotating impeller is driven to rotate by the second driving mechanism. A deformed mud scraping mechanism is installed under the rotating impeller. The reducing part can follow the extension of the telescopic cylinder. Long stretch the deformed mud scraping mechanism and drive the deformed mud scraping mechanism to rotate. The problem that the drilling fluid solid-liquid separation equipment occupies a large area and the separation effect is poor in the prior art is solved.

The invention discloses a winch type sprinkler water pipe desilting device and method. The winch type sprinkler water pipe desilting device comprises a cylinder which is provided with flange plates at two ends and is formed by two buckled half shells. A felt drum is arranged inside the cylinder formed by the two buckled half shells; half blind flanges are respectively arranged at the two ends of the cylinder to press and paste the felt drum onto the two end faces of the cylinder formed by the two buckled half shells; a rotating shaft is symmetrically arranged at the middle part of the cylinder formed by the two buckled half shells; steps are arranged at an end part of the rotating shaft, forming a big end which is stuck in a groove arranged inside the cylinder formed by the two buckled half shells; a rack pipe carriage is fixed on the exposed end of the rotating shaft; and nuts used for fixing the rack pipe carriage are arranged at the two sides of the rack pipe carriage. The desilting device can rotate around the rotating shaft, is simple in structure, convenient to operate, firm and durable and saves time and labor. The felt drum is good in desilting effect without causing damages to the water pipe of the sprinkler and adapts to the angular pitch change of the water pipe.

The invention relates to the technical field of agriculture and particularly discloses an agricultural fertilizing device which comprises a bottom plate. Moving wheels are mounted under one end of thebottom plate and rotationally connected through a driving shaft, a mud scraping component is arranged at one end of each of two sides of the bottom plate, a diesel tank is mounted on one side above the bottom plate, and a fertilizing component is mounted on the other side above the bottom plate. The agricultural fertilizing device is scientific and reasonable in structure and safe and convenientto use; by mud removal steel brushes, mud adhered to surfaces of the moving wheels can be scraped off, difficulty in traveling of the device due to mud adhesion can be effectively prevented, and trafficability of the device in farmland can be greatly improved; by connection threaded pipes, the mud removal steel brushes can be detached and replaced conveniently, and mud removal effects of the mud removal steel brushes can be effectively improved; by limiting clamping seats, fixing lugs and limiting bolts, the mud removal steel brushes can be fixed in mud removal and prevented from shaking, so that excellent mud removal effects are achieved.
