DETAILED DESCRIPTION

[0022] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0023] As shown in Figures 1 to 7 The utility model provides a PLC control's clear water pump automatic water replenishing equipment, including the limit frame 1, the inside of limit frame 1 is seted up with the sliding slot 23, the inside movable mounting of sliding slot 23 has the mounting plate 11, the top fixed mounting of mounting plate 11 has the support platform 3, the inside fixed mounting of support platform 3 has the clear water pump 2, the outside fixed mounting of clear water pump 2 has the support plate 5, two support plate 5 top fixed mounting has the water tank 4, the bottom fixed mounting of water tank 4 has the fixed box 15, the inside movable mounting of fixed box 15 has the communicating pipe 25, and the fixed mounting between communicating pipe 25 and fixed box 15 has the first spring 19, the inside movable mounting of fixed box 15 has the cam 20, and the both ends of cam 20 are penetrated in the inside of fixed box 15, the left side fixed mounting of fixed box 15 has the motor 17, and the output of motor 17 is connected with the one end of cam 20 fixedly, the bottom fixed mounting of fixed box 15 has the connecting pipe 6, and the connecting pipe 6 bottom clear water pump 2 fixed connection, the outside fixed mounting of clear water pump 2 has the electromagnetic liquid level meter 16.

[0024] After PLC receives the signal transmitted by electromagnetic liquid level meter 16, logic judgment will be carried out, according to the preset program and parameter, PLC can judge whether the current liquid level is lower than the set lower limit value or higher than the set upper limit value, once electromagnetic liquid level meter 16 is lower than the lower limit value, PLC will send control signal, start motor 17, drive cam 20 in the inside of fixed box 15 through motor 17, extrude communicating pipe 25 through cam 20, when cam 20 extrudes communicating pipe 25, make cam 20 not coincide with connecting pipe 6 and water tank 4, so that the water in the inside of water tank 4 cannot enter the inside of communicating pipe 25, when cam 20 does not extrude communicating pipe 25, make water tank 4, communicating pipe 25 and connecting pipe 6 coincide, at this time, the water in the inside of water tank 4 enters the inside of connecting pipe 6 through communicating pipe 25, and then enters the inside of clear water pump 2 through connecting pipe 6, complete the water replenishing of clear water pump 2, when electromagnetic liquid level meter 16 reaches or exceeds the upper limit value, PLC will send stop signal, close motor 17, so as to realize the automatic control of liquid level.

[0025] When the PLC receives the signal transmitted by the electromagnetic liquid level meter 16, it will make logical judgments according to the preset program and parameters. When the liquid level is lower than the set lower limit value, the PLC will send a control signal to start the motor 17. The motor 17 works to drive the cam 20 to reciprocate inside the fixed box 15. When the cam 20 presses the communication pipe 25, it will block the connection between the water tank 4 and the connecting pipe 6, preventing water from entering the communication pipe 25. When the cam 20 does not press the communication pipe 25, the water tank 4, the communication pipe 25 and the connecting pipe 6 are coincident. At this time, the water in the water tank 4 enters the water outlet channel connecting pipe 6 through the one-way valve communication pipe 25, and finally flows into the clean water pump 2, completing the water replenishment process. When the liquid level reaches or exceeds the upper limit value, the PLC will send a stop signal to turn off the motor 17. Compared with traditional equipment, the device is convenient for water replenishment of the clean water pump 2 through the cooperation of PLC, motor 17 and electromagnetic liquid level meter 16.

The whole process does not need manual operation. The water replenishment precision of the device is high. The electromagnetic liquid level meter 16 accurately measures the liquid level and feeds back to the PLC in real time. The PLC finely regulates the motor 17 accordingly to ensure that the clean water pump outlet flow and speed are just right, avoiding over or under water replenishment. In addition, the PLC control system is stable and reliable. The motor and clean water pump are made of high-quality materials and advanced technology, which are durable and wear-resistant. The device is energy-saving and environmentally friendly, and adjusts the water replenishment speed and amount as needed, with low operating noise and low energy consumption. At the same time, the self-diagnosis and fault warning function of PLC, combined with the easy maintenance of motor and clean water pump, reduces the maintenance cost. Finally, the automatic water replenishment device maintains the proper liquid level of the container, ensures the continuous and stable production, improves the efficiency and reduces the cost.

[0037] The outer diameter of the mounting block 9 is equal to the inner diameter of the fixed seat 8, and the fixed seat 8 has a smooth surface design.

[0038] The working principle and use process of the utility model are as follows:

[0039] After the PLC receives the signal transmitted by the electromagnetic liquid level meter 16, logical judgment is performed, and according to the preset program and parameters, the PLC can judge whether the current liquid level is lower than the set lower limit value or higher than the set upper limit value. Once the electromagnetic liquid level meter 16 is lower than the lower limit value, the PLC will send a control signal to start the motor 17, which drives the cam 20 to move in the fixed box 15. The cam 20 extrudes the communication pipe 25, and the communication pipe 25 extrudes the inside of the first spring 19 in the fixed box 15. When the cam 20 extrudes the communication pipe 25, the cam 20 does not overlap the connecting pipe 6 and the water tank 4, so that the water in the water tank 4 cannot enter the inside of the communication pipe 25. When the cam 20 does not extrude the communication pipe 25, the water tank 4, the communication pipe 25 and the connecting pipe 6 overlap. At this time, the water in the water tank 4 enters the inside of the connecting pipe 6 through the communication pipe 25, and then enters the inside of the clean water pump 2 through the connecting pipe 6, thereby completing the water replenishment of the clean water pump 2. When the electromagnetic liquid level meter 16 reaches or exceeds the upper limit value, the PLC will send a stop signal to turn off the motor 17, thereby realizing automatic control of the liquid level.

[0040] The staff needs to install the clean water pump 2 in the limiting frame 1. First, the clean water pump 2 is fixedly installed in the supporting table 3, then the handrail 12 is gripped, the mounting plate 11 is aligned with the inside of the sliding groove 23 through the handrail 12, and now the mounting plate 11 is pushed into the inside of the sliding groove 23 through the handrail 12.
