Description

Technical Field

[0001] The invention relates to the technical field of garbage conveying, and in particular to a control system and method for adaptively controlling the lowering height of a river garbage lifting bucket. Background Art

[0002] At present, the lifting mechanism of the domestic waste recycling system for ships traveling on the river is located above the river water level during the dry season, and below the water level during the rainy season, which is inconvenient for garbage delivery. The unstable use environment has a serious impact on the service life of the lifting mechanism of the domestic waste recycling system. In addition, when the lifting mechanism is underwater, it is also a huge threat to the driving safety of passing ships.

[0003] At present, there are three ways to deal with the different positions of the lifting mechanism of the river garbage recycling system on the river water surface in different seasons. One is to manually adjust the height of the lifting mechanism of the river garbage recycling system according to the water surface height in different seasons to achieve the protection of the lifting mechanism; the second is to fix the height of the lifting mechanism so that it is always above the water surface; the third is to replace the materials of the lifting mechanism and other structures with stainless steel, aluminum and other materials that are not easy to rust.

[0004] Although the above three disposal methods can extend the service life of the lifting mechanism, they still have the following defects: First, since the change in water surface height varies with climate and season, it is very uncertain. Therefore, artificially adjusting the height of the lifting mechanism of the river garbage recycling system will increase the labor cost to a certain extent; second, when the river water level is at a low point, the lifting mechanism with a fixed height is not convenient for garbage recycling; third, the lifting mechanism made of stainless steel, aluminum and other materials that are not easy to rust increases the material cost, which is not conducive to the popularization of the recycling system.

[0023] The embodiment of the present application discloses a river garbage lifting bucket lowering height adaptive control system, including: a garbage lifting mechanism 1 and an electrical control cabinet 2.

[0024] Among them, the garbage lifting mechanism 1 includes a lifting track structure 11, a lifting bucket structure 12 and a lifting drive mechanism 13. The lifting bucket structure 12 can be slidably assembled on the lifting track structure 11. The lifting drive mechanism 13 is transmission-connected to the lifting bucket structure 12 to lift or lower the lifting bucket structure 12; the electrical control cabinet 2 is electrically connected to the lifting drive mechanism 13 to control the operation of the lifting drive mechanism 13.

[0025] The present application controls the lifting drive mechanism 13 to lift or lower the lifting bucket structure 12 by setting an electrical control cabinet 2. In this way, there is no need to manually adjust the lifting bucket structure 12, which effectively reduces the labor cost. At the same time, the electrical control cabinet 2 can adjust the lowering height of the lifting bucket structure 12 according to the water level changes to avoid the lifting bucket structure 12 being below the river surface, thereby facilitating the ships to put garbage into the lifting bucket structure 12. In addition, the corrosion of the lifting bucket structure 12 by water vapor can be reduced, thereby effectively extending the service life of the lifting bucket structure 12.

[0026] In some embodiments, a manual switch, a PLC controller, a displacement sensor, a water level sensor and a servo controller are provided in the electrical control cabinet 2. The manual switch is used to control the switch of the power supply. The servo controller, the displacement sensor and the water level sensor are all connected to the PLC controller signal. The servo controller is electrically connected to the lifting drive mechanism 13. The PLC controller controls the servo controller to drive or stop driving the lifting drive mechanism 13 according to the signals currently obtained from the displacement sensor and the water level sensor.

[0027] The manual switch is used to control the power switch to start and stop the system; the water level sensor is used to detect the current water level height in real time, and transmit the water level height signal to the PLC controller, so that the PLC controller determines the descent height of the lifting bucket structure 12 according to the water level height signal; the displacement sensor is used to detect the current descent height of the lifting bucket structure 12 in real time, and transmit the position signal of the lifting bucket structure 12 to the PLC controller, so that when the lifting bucket structure 12 reaches the specified position, the PLC controller can control the servo controller to stop driving the lifting drive mechanism 13, so that the lifting bucket structure 12 stops at the specified position; the servo controller is electrically connected to the lifting drive mechanism 13, and the servo controller can drive or stop driving the lifting drive mechanism 13 by receiving the command signal of the PLC controller.

[0028] By setting the above-mentioned electrical components, the electrical control cabinet 2 can adjust the descent height of the lifting bucket structure 12 in real time according to different water levels to prevent the lifting bucket structure 12 from falling into the river. This can effectively protect the safety of the lifting bucket structure 12 and extend the service life of the lifting bucket structure 12.

[0029] In some embodiments, for example Figure 1 As shown, the lifting drive mechanism 13 includes a winch 131 and a pulley 132. The winch 131 is installed on the river bank and is located below the lifting track structure 11; the pulley 132 is fixedly installed on the top of the lifting track structure 11, and the rope on the winch 131 passes over the top of the lifting track structure 11 and is laid on the pulley 132 to be connected to the lifting bucket structure 12; the winch 131 is electrically connected to the servo controller.

[0030] The winch 131, the roller and the lifting bucket structure 12 constitute a fixed pulley 132 structure. The winch 131 lifts and lowers the lifting bucket structure 12 by winding and releasing the rope. The winch 131 is electrically connected to the servo controller, and the servo controller can drive or stop driving the winch 131 by receiving the command signal of the PLC controller.

[0031] In some embodiments, for example Figure 1 As shown, the lifting track structure 11 includes a lifting track 111 and a track support frame 112. The track support frame 112 is installed on the river bank. The lifting track 111 is installed on the side of the track support frame 112 facing the river and extends along the embankment toward the river surface. In the extension direction, a plurality of fixed brackets 3 are spaced apart between the lifting track 111 and the embankment. The arrangement of the plurality of fixed brackets 3 can effectively enhance the installation stability of the lifting track 111; a supporting beam 1121 is provided at the top of the track support frame 112, and a pulley 132 is fixedly installed on the supporting beam 1121. The rope on the winch 131 passes over the supporting beam 1121 and is laid on the pulley 132 to be connected to the lifting bucket structure 12.

[0032] In some embodiments, for example Figure 1 As shown, the lifting bucket structure 12 includes a lifting bucket 121 and a mounting plate 122 . The lifting bucket 121 is mounted on the mounting plate 122 . A roller is provided at the bottom of the mounting plate 122 , and the roller is movably mounted in the lifting track 111 . A rope is connected to the mounting plate 122 .

[0033] In addition, the present application also discloses a method for adaptively controlling the lowering height of a river garbage lifting bucket, which is applied to the adaptive control system for lowering the river garbage lifting bucket disclosed in the above embodiment, and specifically includes the following contents: Turn on the manual switch in the electrical control cabinet 2 to enable the system to operate; The PLC controller controls the servo controller to drive or stop driving the winch 131 according to the signals currently obtained from the displacement sensor and the water level sensor, thereby causing the winch 131 to control the lifting bucket structure 12 to rise or fall along the lifting track 111.

[0034] In this way, the lowering height of the lifting bucket structure 12 can be adjusted according to the change of water level to avoid the lifting bucket structure 12 being below the river surface, thereby facilitating ships to put garbage into the lifting bucket structure 12. In addition, the corrosion of the lifting bucket structure 12 by water vapor can be reduced, thereby effectively extending the service life of the lifting bucket structure 12.

[0035] In some embodiments, the PLC controller controls the servo controller to drive or stop driving the winch 131 according to the signals of the displacement sensor and the water level sensor currently obtained, so that the winch 131 controls the lifting bucket structure 12 to rise or fall along the lifting track 111, specifically including the following three working conditions: When the lifting bucket structure 12 starts to descend, the water level sensor detects the current water level height and transmits the water level height signal to the PLC controller. The PLC controller determines the descent height of the lifting bucket structure 12 according to the current water level height signal, and controls the servo controller to drive the winch 131 to operate, so that the lifting bucket structure 12 descends along the lifting track 111. The displacement sensor monitors the descent height of the lifting bucket structure 12 in real time, and transmits the position signal of the lifting bucket structure 12 to the PLC controller. When the lifting bucket structure 12 descends to the specified position, the PLC controller controls the servo controller to stop driving the winch 131 to operate, so that the lifting bucket structure 12 stops at the specified position. When the lifting bucket structure 12 starts to be lifted, the PLC controller controls the servo controller to drive the winch 131 to operate, so that the lifting bucket structure 12 rises along the lifting track 111. When the lifting bucket structure 12 rises to the top of the lifting track 111, the lifting bucket structure 12 flips over to dump the garbage out. When the lifting bucket structure 12 starts to reset, the PLC controller controls the servo controller to drive the winch 131 to operate, so that the lifting bucket structure 12 descends along the lifting track 111, and the displacement sensor monitors the descending height of the lifting bucket structure 12 in real time, and transmits the position signal of the lifting bucket structure 12 to the PLC controller. When the lifting bucket structure 12 descends to its original position, the PLC controller controls the servo controller to stop driving the winch 131 to operate, so that the lifting bucket structure 12 is parked in its original position.
