For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0018] Please see Figure 1-2 This utility model provides a technical solution: a sealed water level controller, including a first level gauge 2 and a second level gauge, wherein the first level gauge 2 is installed in a pump house water tank 1 and is connected to a transmitting device 3; the second level gauge is installed in a water source 4, and a pipeline connects the pump house water tank 1 and the water source 4, with a water pump 5 installed at the end of the pipeline in the water source 4, and the water pump 5 is equipped with a receiving device, and the water pump 5 is electrically connected to a PLC controller 15 via a 4G network; the second level gauge is installed in the water source 4, and the second level gauge includes a float 6, with a vertical rod fixedly connected to the upper end of the float 6. A floating rod 14 is set vertically. A magnetic device 13 is provided at the upper end of the floating rod 14. A sliding device 12 is provided on the floating rod 14. The sliding device 12 includes a groove 1204 opened on one side of the floating rod 14. A slider 1203 is provided in the groove 1204 and slides with the groove 1204. A sliding rod 1201 is vertically installed on the slider 1203. Sliding sleeves 1202 are provided at both ends of the sliding rod 1201. The sliding sleeves 1202 are fitted on the outer side wall of the floating rod 14. The sliding rod 1201 is fixedly installed on a support rod. The support rod is set on the upper side wall of the water source 4.
[0019] Furthermore, the upper and lower parts of the support frame 7 are respectively provided with a first Hall sensor 8 and a second Hall sensor 9.
[0020] Furthermore, the second level gauge is also equipped with an alarm device, which includes a first alarm controller 10 and a second alarm controller 11. The first alarm controller 10 and the second alarm controller 11 are mounted on the support frame 7 and are positioned above the second Hall sensor 9 on the support frame 7.
[0021] Furthermore, the first alarm controller 10 is installed at the same height as the first Hall sensor 8, and the second alarm controller 11 is installed at the same height as the second Hall sensor 9.
[0022] Furthermore, the PLC controller 15 is electrically connected to the transmitting device 3 and the receiving device, and the PLC controller 15 is also electrically connected to the Hall sensor and the alarm controller.
[0023] In Example 1, during actual use, the first level gauge 2 of the pump room water tank 1 collects the water level information of the pump room water tank 1, converts it into an electrical signal through the transmitting device 3, and transmits it to the receiving device. When the signal from the transmitting device 3 indicates that the water level of the pump room water tank 1 is low, the water pump 5 receives the signal and automatically starts through the PLC controller 15 to transport water from the water source 4 into the pump room water tank 1. Conversely, when the signal from the transmitting device 3 indicates that the water level of the pump room water tank 1 is not lower than the production requirements, the water pump 5 automatically shuts down and stops transporting water.
[0024] In Example 2, a second level gauge is installed on the water source 4. When the water level in the water source 4 is too high, the first Hall sensor approaches the magnetic device 13, which triggers the first Hall sensor. The first Hall sensor transmits a signal to the PLC controller 15, which then sends a feedback signal to the water pump 5, causing the water pump 5 to start pumping water. When the water level in the water source 4 is too low, the second Hall sensor approaches the magnetic device 13, which triggers the second Hall sensor. The second Hall sensor transmits a signal to the PLC controller 15, which then sends a feedback signal to the water pump 5, causing the water pump 5 to stop pumping water. This achieves a low-stop, high-start function based on the water level. This solves the technical problems of existing technologies that rely entirely on manual control of the water level, which is time-consuming, labor-intensive, and unreliable. It avoids damage to the water source 4 or the water pump 5 from running dry and burning out, and provides sensitive, reliable, time-saving, and labor-saving monitoring.
[0025] The alarm device includes a first alarm controller 10 and a second alarm controller 11. When the water level at water source 4 is too high, the first Hall sensor 8 approaches the magnetic device 13. At this time, the first alarm controller 10 approaches the first Hall sensor 8, and the first Hall sensor transmits a signal to the PLC controller 15. The controller feeds back a signal to the water pump 5, and the water pump 5 starts pumping water. When the water level at water source 4 is too low, the second Hall sensor 9 approaches the magnetic device 13. At this time, the second alarm controller 11 approaches the second Hall sensor 9, and the second Hall sensor transmits a signal to the PLC controller 15. The controller feeds back a signal to the water pump 5, and the water pump 5 stops pumping water. The PLC controller 15 activates the alarm and issues an alarm. Please refer to [link to relevant documentation]. Figure 3When SB2E (remote start button) is pressed, the PLC receives a start signal and then controls KM1 to close via internal logic, thereby connecting the controlled circuit. When SB1E (remote stop button) is pressed, the PLC receives a stop signal and then controls KM1 to open via internal logic, thereby disconnecting the controlled circuit.
[0026] The HG1C indicator light is connected to the FR1 thermal relay. When the motor or other equipment is overloaded, the FR1 will activate, disconnect the circuit, and display the fault status through the indicator light.
[0027] The circuit has a signal feedback mechanism so that the PLC or other control devices can know the real-time status of the circuit or device; for example, the closed state of KM1 may be returned to the PLC through a certain feedback signal, and the PLC can determine whether the circuit has been successfully started based on this signal.
[0028] Overload protection for the motor is achieved through the FR1 thermal relay. When the motor current exceeds the set value, the FR1 will activate, disconnect the circuit, and protect the motor from damage.
[0029] As the main power switch, QF1 can easily cut off the power to the entire circuit when necessary, providing a safety guarantee for circuit maintenance or troubleshooting.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
