The utility model discloses an automatic docking and task execution system for main linear motion carrier corollary equipment, which is characterized in that a relative displacement automatic control mechanism, a task execution mechanism, a pipeline power supply storage mechanism, a lifting mechanism and a task execution end position adjusting mechanism are integrally and intelligently designed; splicing and assembling can be selected according to actual requirements so as to be suitable for different application scenes, and compared with the prior art that reserved water scheduling and waste liquid collecting operation of main linear motion carrier corollary equipment such as high-speed rails and bullet trains are completed through manpower, the purposes of reducing staff, improving efficiency and improving operation efficiency can be achieved; therefore, under the condition that no personnel intervention exists basically, the purposes of automatic rapid supply of stored water of high-speed rails and trains, waste liquid collection and automatic positioning, butt joint and task execution of task terminals of other main linear motion carrier corollary equipment are achieved, the personnel use cost is reduced, the water supply efficiency is improved, and the train stopping operation time is greatly shortened.

The utility model provides a direct insertion type agricultural irrigation water hose which comprises a main pipe body and a plurality of diversion through holes which are formed in the axial direction of the main pipe body at intervals and penetrate through the main pipe body, and branch connecting assemblies are arranged at the diversion through holes. The branch connecting assembly comprises a connecting base and a branch water pipe connecting piece. The connecting base is provided with a central through hole communicated with an internal channel of the main pipe body, and the branch water pipe connecting piece is in pressure self-tightening type detachable inserting connection with the connecting base through a conical interference fit interface; the connecting base comprises a lap joint block fixedly connected with the inner wall of the main pipe body and a butt joint part penetrating through the diversion through hole and extending to the outer side of the main pipe body, and the butt joint part forms a conical matching structure matched with the branch water pipe connecting piece; the branch water pipe connecting piece is provided with a penetrating type flow channel, and the penetrating type flow channel, an inner channel of the main pipe body and a central through hole of the base unit jointly form a continuous unobstructed fluid channel. The branch water pipe connector is convenient to use, and rapid and reliable sealing connection between the branch water pipe connector and the connecting base can be achieved without too large insertion and extraction force.

The application discloses a secondary water supply control method, system, medium and equipment, and relates to the technical field of secondary water supply. The method comprises the following steps: acquiring floor information of a target floor for holding an activity in a high-rise building and activity information, wherein the floor information comprises a floor height and water supply equipment information corresponding to the target floor; determining a target water supply pressure of the target floor according to the floor height and the water supply equipment information; predicting water supply demand information of the target floor according to the activity information; and determining a water supply decision of the target floor according to the target water supply pressure and the water supply demand information. The technical scheme provided by the application can effectively predict and meet the variable water supply demand of holding an activity in a high-rise building, and improve the water supply efficiency.
