Automatic control device for floating winding type plastic cloth of salt pond

Abstract

Th invention relates to an automatic control device for a floating winding type plastic cloth of a salt pond. The automatic control device is characterized in that the automatic control device comprises the plastic cloth, a floating winding shaft, a floating winding shaft motor, a floating winding shaft reduction gearbox, a traction floating plate, a floating plate traction rope, a winding drum, a winding drum reduction gearbox, a winding drum motor and a control device body; one end of the plastic cloth is wound around the floating winding shaft; the floating winding shaft is driven by the floating winding shaft motor and the floating winding shaft reduction gearbox; the other end of the plastic cloth is fixed to the traction floating plate; the traction floating plate is connected with the winding drum through the floating plate traction rope in a wound mode; the winding drum is driven by the winding drum motor and the winding drum reduction gearbox; the floating winding shaft motor and the winding drum motor are controlled by the control device body synchronously. The automatic control device is scientific and reasonable in design. The key technical problem of automatic control over a plastic cloth system of the salt pond is solved. Automatic cooperative control over the whole process of spreading and traction of the plastic cloth in the floating winding type plastic cloth system is achieved.

Description

technical field [0001] The invention relates to plastic thatch equipment for a crystallization pool in a salt field, in particular to an automatic control device for a floating roll type plastic thatch in a salt pond. Background technique [0002] At present, the salt pond plastic thatch system used in the salt field basically does not have automatic control functions. The operation of the equipment is completely operated by the operator manually or by remote control. Both motors run at a power frequency of 50Hz, and their angular velocity is constant. As the unwinding proceeds, the diameter of the outer edge of the plastic cloth wound on the floating reel gradually decreases. At the same time, the traction rope wound on the reel On the contrary, the diameter of the outer edge of the machine gradually increases.

Problems solved by technology

[0002] At present, the salt pond plastic thatch system used in the salt field basically does not have automatic control functions. The operation of the equipment is completely operated by the operator manually or by remote control. Both motors run at a power frequency of 50Hz, and their angular velocity is constant. As the unwinding proceeds, the diameter of the outer edge of the plastic cloth wound on the floating reel gradually decreases. At the same time, the traction rope wound on the reel Instead, the diameter of the outer edge gradually increases. Therefore, in manual operation, the two motors must be started and stopped, and the unwinding speed must be coordinated through manual intervention.

Therefore, there are serious defects and deficiencies in the existing control methods, that is, it is difficult to realize the real synchronization of deployment and traction during operation, and the plastic cloth (plastic tarpaulin) often appears too loose and too tight.

When it is too loose, the plastic cloth (plastic tarpaulin) will roll back at the holding roller, causing tearing of the cloth; The service life of the cloth (plastic thatch cloth), if the tension is too large, the large rope may break and the floating reel may be pulled out from the holding roller and broken.

In addition, each salt pond requires at least 2-3 operators

Simultaneous deployment of multiple salt pools cannot be realized
