Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

Example (b):

referring to fig. 1, the present embodiment provides an automatic lifting/lowering raft device, which includes a rectangular raft 1, wherein the raft 1 floats in a pool for mounting a fountain assembly.

All be equipped with driving piece 2 in the four corners department of raft 1, it is concrete, all set up a driving piece 2 in every corner of raft 1, through the lift of driving piece 2 control raft 1, it is concrete in this embodiment:

referring to fig. 2, the driving member 2 includes a winding machine 21 fixedly installed at a corner of the floating raft 1, and a cable 22 wound on the winding machine 21, one end of the cable 22 is wound on a winding wheel of the winding machine 21, and the other end of the cable is connected to a counterweight 23 placed at the bottom of the pool, wherein the counterweight 23 may be a cement block poured with cement, and the cement block is fixedly connected to one end of the cable 22 to fix the end of the cable 22.

When a certain angle of the floating raft 1 needs to float upwards, the winding wheel of the winch 21 rotates to gradually unwind the cable 22, so that the angle of the floating raft 1 gradually rises under the buoyancy; on the contrary, when a certain angle of the floating mat 1 needs to be sunk, the winding wheel of the winch 21 rotates reversely to wind the cable 22 step by step, and the counterweight 23 has larger gravity, so that the winch 21 can sink relative to the counterweight 23 while winding, thereby driving the floating mat 1 to sink at the angle.

The driving members 2 are electrically connected with a controller, and the controller is used for controlling the driving members 2 to act, specifically, the windlass 21 in the driving members 2 is connected with the controller, wherein the controller can be a plc controller, and specifically, a SIMATIC S7-300 controller can be adopted.

In this embodiment, the liquid level sensors 3 are disposed at four corners of the floating bar 1, and the liquid level height of the corner of the floating bar 1 is detected by the liquid level sensors 3, wherein the liquid level sensors 3 may be liquid level sensors of the OMEGA PX709GW series, or may be other types of liquid level sensors, which is not limited herein.

Every corner at the floating raft 1 all sets up 2 level sensor 3, so when one of them level sensor 3 broke down, another level sensor 3 can continue work and use, guarantees that whole device can continue normal operating.

The liquid level sensors 3 are electrically connected with the controller, the controller controls the action of the winch 21 at the corner of the floating bar 1 where the liquid level sensor 3 is located according to the output signals of the liquid level sensors 3, for example, the liquid level sensor 3 at the upper left corner of the floating bar 1 is recorded as the liquid level sensor 1# 3, the winch 21 at the upper left corner of the floating bar 1 is recorded as the winch 1# 21, and the controller controls the action of the winch 1# 21 according to the output signals of the liquid level sensor 1# 3.

The implementation principle is as follows: the device mainly comprises the following steps when in work:

s100, placing the floating raft 1, the winch 21 and the balancing weight 23 in a water pool, floating the floating raft 1 in the water pool under the buoyancy, and detecting an actual water level signal of a corner of the floating raft 1 by the liquid level sensor 3 on the floating raft 1.

S200, performing initial setting on the controller: for each level sensor 3, an initial signal value representing the reference level height of the level sensor 3 is input into the controller, and the initial signal value is used as a reference standard.

S300, when the actual water level signal value output by the liquid level sensor 3 at a certain corner of the floating raft 1 is lower than the initial signal value (namely, the liquid level height at the corner is lower than the preset liquid level height), the controller controls the action of the winch 21 at the corner to enable the winch 21 to unwind the cable 22, so that the corner floats upwards until the corner floats upwards to the preset liquid level height, and at the moment, the corner of the floating raft 1 is at the preset liquid level height.

When the actual water level signal value output by the liquid level sensor 3 at a corner of the floating mat 1 is higher than the initial signal value (i.e. indicating that the liquid level at the corner is higher than the preset liquid level), the controller controls the action of the winch 21 at the corner to make the winch 21 wind the cable 22, so that the corner sinks until the corner sinks to the preset liquid level and stops, and at this time, the corner of the floating mat 1 is at the preset liquid level.

And repeating the step S300 by the liquid level sensors 3 and the windlasses 21 at other corners, so that each corner of the floating raft 1 can be adjusted to the reference liquid level height, and the inclination degree of the floating raft 1 can be automatically adjusted.

Above only the typical example of the utility model discloses, in addition, the utility model discloses can also have other multiple concrete implementation manners, all adopt the technical scheme that equivalent replacement or equivalent transform formed, all fall in the utility model discloses the scope of claiming.
