In a comparative example, each ship loader is only allowed to stop for manual water supply once in a single shift (12 hours) in winter, and the requirement of 12-hour water spraying of the ship loader can be met once every time water supply is carried out, so that the manual water supply of each ship loader is 9 × 10-90 m3(cubic meter). Wherein, the existing water tank (9 m)3) Water can be sprayed for nearly one hour; each loader for a single shift is counted by 10 hours of watering. From the calculation results, each ship loader must have a water tank for storing 90 cubic meters (90 cubic meters of clean water weighs 90 tons) to meet the one-time water supply condition, and considering that each ship loader has a 9 cubic meters water tank, a new water tank for storing 80 cubic meters (80 tons) needs to be establishedThe water tank (if the water tank to be added is larger in 12 hours).
For a ship loader, an independent carrying platform is normally established at the tail of a tail car for setting a large water tank, the carrying platform needs to be synchronous with the ship loader in walking and is provided with a driving device, the design and installation difficulty of the carrying platform is high, and the investment cost is high; meanwhile, the defects of manual water feeding are not eliminated, and the requirement that the ship loader feeds water at a longer interval is met, so that the water spraying time is prolonged. But does not fulfill the requirement of automatic water supply in full time in the complete sense.
The embodiment of the application solves the problem of full-time and seamless joint water supply between the ship loader and the wharf water supply point water outlet pipe, and realizes full-time automatic water supply of the ship loader. In addition, this application embodiment can adopt miniature electric putter to promote response iron to trigger proximity switch's mode control solenoid valve's the disconnection, has solved water supply point and has received the water point to be affiliated to two different system devices of spatial separation, control signal transmission difficulty each other, causes the difficult problem of control to a great deal of drawback that has eliminated unit manual work water feeding, basin water supply existence.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present application. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present application shall be subject to the appended claims.
