The pipeline system comprises a water pump, a water pumping motor, a tee joint, a water inlet pipe, a water pumping pipe and a water outlet pipe. The water pumping motor and the water pump are both located between the water tank and a car seat and are both fixed to the car frame. The water outlet pipe is connected with the water pump. The water pumping motor is connected with the battery through a voltage control circuit. The electric three-wheel sprinkler car solves the defects in the prior art and has the advantages of being small in size, flexible and convenient to use and capable of being applied to landscaping, agricultural irrigation, forest watering, forest spraying and the like.

A method for preparing a multi-substituted bromofluorine-substituted benzoimidazole compound, which is prepared by using a special reaction kettle, the reaction kettle has a glass body (1), the body is equipped with a kettle cover (11), a lower flange (12 ), barrel (13), and the reactor also includes an inlet combination (2), an outlet combination (3), a fixture (4), a stirring portion (5); it is based on 2-bromo-5-fluoroaniline as a synthetic starting point , to obtain (E)-N-(2-bromo-5-fluorophenyl)-2-(hydroxylamine) acetamide, and then prepare 7-bromo-4-fluoroindoline-2,3-dione ; Then through 2-amino-3-bromo-6-fluorobenzoic acid transition; 7-bromo-4-fluoro-1H-phenyl [d] imidazole-2-alcohol; add ethyl acetate and phosphorus oxybromide , to obtain the product 2,7-dibromo-4-fluoro-1H-phenyl[d]imidazole.

The invention discloses a filtering water cup which comprises a cup body, a filter element, a water storage shell and a cup lid. The lower end of the water storage shell and the cup body are connected in a detachable and sealed mode, and the upper end of the water storage shell and the cup lid are connected in a detachable and sealed mode. The inner wall of the water storage shell and the periphery of the filter element are in sealed connection. A water storage cavity is formed among the filter element, the cup lid and the water storage shell. A vent pipe communicated with the water storage cavity and an inner cavity of the cup body is arranged on the filter element in a penetrating mode. A ventilation switching device is arranged inside the vent pipe. The ventilation switching device blocks the vent pipe when the filtering water cup is installed forward, and is communicated with the vent pipe when the filtering water cup is installed reversely. When the water cup contains water, the water storage shell and the cup lid are taken down, water is directly added into the cup body, and the water storage shell and the cup lid are fixed to a cup opening; during filtering, the water cup is installed reversely, gas inside the water storage cavity enters the cup body through the vent pipe, and water inside the cup body flows into the water storage cavity through the filter element, so that filtering is achieved. According to the filtering water cup, the water containing operation is quite convenient, the filtering mode is simple and easy to implement, and the user experience is improved.

A method for preparing difluoromethoxy multi-substituted nitrogen-containing heterocyclic compounds, which is prepared by using a special reactor, the reactor has a glass body (1), the body is equipped with a lid (11), a lower convex Edge (12), barrel (13), and the reactor also includes an air inlet combination (2), an air outlet combination (3), a fixing device (4), a stirring part (5), and a cooling pump tank (6); ‑Bromo‑3‑fluoropyridine is used as a starting point for synthesis to obtain 2‑bromo‑3‑fluoropyridine‑4‑boronic acid, which is then prepared to obtain 2‑bromo‑3‑fluoro‑4‑hydroxypyridine; and then through 2‑bromo‑3 Transition of fluoro-4-difluoromethoxypyridine; 3-fluoro-4-difluoromethoxypyridine-2-formic acid ethyl ester; low temperature reaction under nitrogen protection to obtain 3-fluoro-4-difluoromethoxy base pyridine-2-methanol, and react at room temperature to obtain the final product 3-fluoro-4-difluoromethoxypyridine-2-formaldehyde.

The invention relates to an underwater protection device with a propulsion device for an underwater robot, which includes a cover body. The outer wall of the cover is provided with a plurality of uniformly arranged water inlet holes, and the water inlet holes are fixed with the inner wall of the cover body. The fixed rod, the side wall of the water inlet is provided with an arc-shaped cavity, the fixed rod is fixed with a positioning rod in the same direction as the water inlet, the positioning rod is covered with a baffle plate slidingly connected with it, and the baffle plate There is a spring socketed on the outer wall of the positioning rod between the fixed rod and the spring is squeezed to cover the stop plate on the water inlet hole so that the surface of the cover body is smooth and the resistance is reduced for easy advancement, avoiding the uneven surface from affecting the advancement of the propulsion device and not It will affect the normal water intake of the water inlet hole. When the cylinder moves to the position of the water inlet hole, because the water pressure is greater than the pressure in the cover, the baffle plate will be opened to facilitate the internal water filling. When the cylinder is moved to a staggered position, the water inlet will be blocked. The hole stops water intake, and the buffer spring acts as a buffer to reduce the unstable shaking caused by the impact force generated when water rushes in.
