The single machine device is an efficient continuous loading and unloading machine, is widely applied to bulk material storage yards of ports, iron and steel plants, large-scale thermal power plants and the like, and is used for loading and unloading bulk materials such as ores, coal, sand and the like. In general, the stacking operation of the stacker is as follows: bulk materials conveyed by the belt conveyor are unloaded to the belt conveyor on the arm support through the tail car and are thrown to a stock ground from the front end of the arm support. Through the operation of the stacker, the rotation and pitching of the arm support can enable the material pile to form a regular shape with a trapezoidal section. The material taking working process of the material taking machine is as follows: the material is unloaded onto a belt conveyor of the reversely running arm support through a stripper plate and then unloaded onto a material yard belt conveyor through a hopper below the center for transportation. Through the operation of the reclaimer, the rotation and the pitching of the arm support can enable the bucket wheel to completely take out the materials of the storage pile.

During operation, the single machine needs to be moved frequently along a track with a length of, for example, 700 meters for performing the relevant operation. When the water quantity in the water tank of the single-machine device is insufficient, the device needs to be stopped and synchronously water feeding operation is carried out when the device is moved to a specified position. However, when the single-machine device is shut down, the electromagnetic valve on the water supply pipeline cannot be opened in time, that is, the water tank of the single-machine device cannot be supplied with water in time, and the water supply can be realized only after manual further operation and treatment, so that the working efficiency is low.

Thus, when the water pump is operated, sufficient water pressure is provided to convey the water in the water supply pipe 93 to the water receiving funnel 96, and the water receiving funnel 96 collects the water delivered from the water supply pipe 93 and conveys the collected water to the water tank 91. In addition, when the single-machine device moves a designated water feeding position along the rail, the opening area of the water receiving funnel 96 is large, and the water receiving funnel is easily aligned with the water outlet end of the water feeding pipeline 93 arranged on the dam foundation 80, so that even if the stop position of the single-machine device has an error with the designated water feeding position, the water at the water outlet end of the water feeding pipeline 93 can be conveyed to the water receiving funnel 96, and can be conveyed to the water tank 91 by the water receiving funnel 96.

As an example, the first signal transceiving terminals are the transmitting terminals of the optoelectronic switch, and the number of the first signal transceiving terminals is two, for example, one of the first signal transceiving terminals is used as the transmitting terminal during the track forward driving process, that is, during the single-machine device driving along the track forward, the transmitting terminal will operate and transmit signals to the second signal transceiving terminal, and the controller 92 controls the solenoid valve 94 to open to perform water feeding when the transmitting terminal is aligned with the second signal transceiving terminal; the other first transceiver terminal is used as a transmitting terminal during the track reverse driving, that is, during the single-machine device driving along the track reverse direction, the transmitting terminal will operate and transmit signals to the second transceiver terminal, and the controller 92 controls the solenoid valve 94 to open for water feeding when the transmitting terminal is aligned with the second transceiver terminal.

Further, the single unit device further includes a heat tracing band 97, the heat tracing band 97 is electrically connected to the controller 92, and the heat tracing band 97 is disposed along the water supply pipe 93. When the controller 92 determines that the temperature of the water in the water supply pipeline 93 is lower than the preset temperature, the heat tracing band 97 is correspondingly controlled to perform heating operation, so that the temperature of the water in the water supply pipeline 93 is increased. Therefore, in winter, the water supply pipeline 93 is heated through the heat tracing band 97, icing in the water supply pipeline 93 caused by too low water temperature in the water supply pipeline 93 can be avoided, and water can be smoothly conveyed to the water tank 91 of the single unit device by the water supply pipeline 93.

In an embodiment, referring to fig. 1 and fig. 2 again, a method for supplying water to a single-machine apparatus according to any one of the above embodiments includes the following steps:

if the water tank 91 needs to be added with water, the single machine device moves to the designated water feeding position along the rail and stops, and when the single machine device moves to the designated water feeding position, the swing arm 21 correspondingly contacts the rotating plate 50 and enables the rotating plate 50 to rotate so as to enable the first signal receiving and transmitting terminal 71 and the second signal receiving and transmitting terminal 72 to be aligned with each other;

after the first transceiving signal terminal 71 and the second transceiving signal terminal 72 are aligned with each other, the controller 92 controls the electromagnetic valve 94 to open for filling water into the water tank 91, and correspondingly controls the electromagnetic valve 94 to close if the water level in the water tank 91 is higher than the preset range.

In the water feeding method of the single machine device, even if the stop position of the single machine device has high deviation with the designated water feeding position, the first signal receiving and transmitting end 71 on the swing arm 21 and the second signal receiving and transmitting end 72 on the rotating plate 50 can be aligned under the driving action of the swing arm 21, so that the signals are transmitted, the water feeding operation of the water tank 91 of the single machine device is realized in time, and the water feeding efficiency can be improved.

Further, the method for supplying water to the single-machine unit further includes the steps of determining whether the temperature of water in the water supply pipeline 93 is lower than a preset temperature, and controlling the heat tracing band 97 to perform a heating operation to increase the temperature of water in the water supply pipeline 93 when the temperature of water in the water supply pipeline 93 is determined to be lower than the preset temperature. The preset temperature is set according to actual requirements, and is not limited herein. Therefore, in winter, the water supply pipeline 93 is heated through the heat tracing band 97, icing in the water supply pipeline 93 caused by too low water temperature in the water supply pipeline 93 can be avoided, and water can be smoothly conveyed to the water tank 91 of the single unit device by the water supply pipeline 93.
