Description

Technical Field

[0001] This utility model relates to the field of well technology, specifically to a well abnormal vibration warning device. Background Technology

[0002] A well is a device used to extract groundwater. It typically includes a pump, motor, control system, and pipes. Wells are usually installed near a water source, using underground machinery to extract groundwater and deliver it to the site of use. Surface-mounted wells are installed on the ground surface, drawing groundwater through suction pipes; they are easier to maintain. However, when mechanical components such as the pump and motor malfunction, such as damaged bearings, rotor imbalance, or misaligned couplings, the well can vibrate. These malfunctions usually require inspection and repair by professionals. The existing technology has the following problems:

[0003] Because when existing wells experience abnormal vibrations, if the vibration frequency is relatively slight, it will be difficult for maintenance personnel to detect them. The lack of warning devices can delay maintenance, potentially leading to more serious consequences and unnecessary property damage. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 , Figure 2 As shown, this utility model provides a well abnormal vibration warning device, including a well monitoring box 1. A control compartment 2 is located on the right side of the well monitoring box 1. An inspection door 3 is hinged to the front of the well monitoring box 1. A water pumping pipe 11 is installed inside the well monitoring box 1, with its upper and lower ends extending to the upper and lower sides of the well monitoring box 1, respectively. An electromagnetic flow meter 12 is installed below the outer wall of the water pumping pipe 11, and an electrically controlled butterfly valve 13 is installed above the outer wall of the water pumping pipe 11. A sensor positioning mechanism 14 is sleeved in the middle of the outer wall of the water pumping pipe 11. The sensor positioning mechanism 14 is located at... Between the electrically controlled butterfly valve 13 and the electromagnetic flow meter 12, a wireless data acquisition device 15 and an RTU telemetry terminal 16 are fixedly installed on the left side of the inner wall of the well monitoring box 1. The RTU telemetry terminal 16 is located above the wireless data acquisition device 15. The signal output terminal of the RTU telemetry terminal 16 extends to the left side of the well monitoring box 1 and is electrically connected to a signal antenna 161. The signal antenna 161 is fixedly installed on the left side of the well monitoring box 1. A pole 17 is fixedly installed at the bottom of the inner wall of the well monitoring box 1. The top of the pole 17 extends to the top of the well monitoring box 1 and is fixedly installed with a solar panel 171.

[0024] The bottom end of the pumping pipe 11 is used to connect to the top of the well, so as to facilitate the pumping out of the water source. At the same time, the flow rate can be monitored when the water source passes through the electromagnetic flow meter 12, and the water source can be pumped out at any time by the electric control butterfly valve 13. The power of the internal electronic components of the overall well monitoring box 1 can be absorbed by the solar panel 171 at the top of the pole 17 and converted into electrical energy and stored in the battery 22. At the same time, the wireless acquisition device 15 and the RTU telemetry terminal 16 can be installed on the left side of the inner wall of the well monitoring box 1 using bolts, and the signal antenna 161 is installed on the left side of the well monitoring box 1.

[0025] like Figure 3 , Figure 4As shown, the sensor positioning mechanism 14 includes a semi-circular clamping plate 141, a semi-circular clamping plate 142 hinged to the left end of the semi-circular clamping plate 141, a mounting plate 144 fixedly mounted to the right end of the semi-circular clamping plate 141, and a mounting plate 143 fixedly mounted to the right end of the semi-circular clamping plate 142. Both the mounting plate 143 and the mounting plate 144 have through holes extending from front to back, and a fixing bolt 145 is provided in the inner circle of the through hole. The rear end of the fixing bolt 145 extends to the rear side of the mounting plate 143, and a nut 146 is threaded onto the outer wall of the fixing bolt 145. A vertical plate 1411 is fixedly mounted at the top center of both the semi-circular clamping plate 141 and the semi-circular clamping plate 142. Both vertical plates 1411 have threaded holes 1412 extending from front to back, and threaded rods 14 are threaded onto the inner circle of both threaded holes 1412. 13. Pressure plates 1415 are fixedly installed on the opposite ends of the two threaded rods 1413. Knobs 1414 are fixedly installed on the opposite ends of the two threaded rods 1413. The top pressure plate 1415 of the semi-circular clamp 141 has a through mounting hole, and a vibration sensor 1417 is fixedly installed on the inner ring of the mounting hole. The rear end of the vibration sensor 1417 overlaps with the outer wall of the water pumping pipe 11. The front signal output end of the vibration sensor 1417 is electrically connected to a wire 1418. The other end of the wire 1418 is electrically connected to the signal input end of the wireless acquisition device 15. Rubber pads 1419 are fixedly adhered to the lower side of the opposite surfaces of the two pressure plates 1415. Limiting slide rods 1416 are fixedly installed on the opposite back sides of the two pressure plates 1415. The two limiting slide rods 1416 are slidably connected to the two upright plates 1411 respectively.

[0026] By opening the semicircular clamp 141 and the semicircular clamp 2 142, fitting them onto the outer wall of the water pumping pipe 11, and then merging them together, the mounting plate 143 and the mounting plate 2 144 are merged, and the through holes are aligned. Then, the fixing bolt 145 is passed through the through holes in the mounting plate 2 144 and the mounting plate 143, and tightened with the nut 146. This allows the semicircular clamp 2 142 and the semicircular clamp 141 to be completely fitted onto the outer wall of the water pumping pipe 11. Then, the knob 1414 on one side of the top upright plate 1411 of the semicircular clamp 141 and the semicircular clamp 2 142 can be rotated simultaneously. This drives the threaded rod 1413 to move closer to the water pumping pipe 11 through the threaded connection with the threaded hole 1412, causing the pressure plate 1415 to clamp the water pumping pipe 11 using the rubber pad 1419. This ensures the stability of the semicircular clamp 141 and the semicircular clamp 2 142. When the pressure plate 1415 on the semi-circular clamp 141 is close to the water pipe 11, the vibration sensor 1417 can contact the water pipe 11, thereby detecting the vibration frequency generated by the water pipe 11 and measuring the vibration frequency under normal conditions. Once the vibration frequency changes, it can be transmitted to the wireless acquisition unit 15 through the wire 1418. The wireless acquisition unit 15 will send the electrical signal to the RTU telemetry terminal 16 through the signal transmission module. The RTU telemetry terminal 16 can then send a vibration warning signal through the signal antenna 161 to quickly notify maintenance personnel. The vibration sensor 1417 consists of a vibration sensing element and a signal output circuit. The vibration sensing element can convert the object vibration signal into an electrical signal, and the signal output circuit can amplify and process the converted electrical signal, and finally output a readable voltage or current signal.

[0027] like Figure 5 As shown, a door 21 is hinged to the right side of the control cabin 2. A battery 22, a circuit breaker 23, an electricity meter 24, and a current transformer 25 are fixedly installed on the lower right side of the inner wall of the control cabin 2. The battery 22 is located behind the circuit breaker 23, the electricity meter 24 is located above the battery 22, and the current transformer 25 is located above the circuit breaker 23. A measurement and control terminal 26, a wiring terminal 27, and a solar controller 28 are fixedly installed on the upper right side of the inner wall of the control cabin 2. The wiring terminal 27 is located in front of the measurement and control terminal 26, and the solar controller 28 is located above the wiring terminal 27.

[0028] The battery 22 inside the control compartment 2 is used to store the electrical energy converted by the pole 17. The circuit breaker 23 can protect the circuit from overload and automatically cut off the power supply. The meter 24 is used to check the power consumption of the electronic equipment inside the well monitoring box 1. The current transformer 25 can convert the large current in the primary circuit into a smaller standard current for use by the secondary equipment. The measurement and control terminal 26 is used to process and send the information data of the electromagnetic flow meter 12. The solar controller 28 is responsible for accurately adjusting the charging voltage and current according to the battery type and status to avoid overcharging of the battery 22. At the same time, it can also effectively adjust the discharge voltage to prevent the battery 22 from over-discharging. The wiring terminal 27 facilitates the connection of wires of various electronic components inside the control compartment 2. Many of the electronic components in the control compartment 2 belong to the existing technology of well flow monitoring, so the specific functions and connection methods will not be described in detail here.

[0029] The working principle of the abnormal vibration warning device for the well is explained in detail below.

[0030] like Figure 1-5As shown, the bottom end of the pumping pipe 11 is used to connect to the top of the well, thus facilitating the extraction of water. Simultaneously, the flow rate can be monitored as the water passes through the electromagnetic flow meter 12, and the water source can be extracted at any time by using the electrically controlled butterfly valve 13 to shut off the pumping pipe 11. The power of the internal electronic components of the overall well monitoring box 1 can be absorbed by the solar panel 171 at the top of the pole 17 and converted into electrical energy stored in the battery 22. The wireless data acquisition device 15 and the RTU telemetry terminal 16 can be installed on the left side of the inner wall of the well monitoring box 1 using bolts, and the signal antenna 161 can be installed on the left side of the well monitoring box 1. After installation, the semi-circular clamp 141 and semi-circular clamp 142 can be opened, and... After being fitted onto the outer wall of the pumping pipe 11, the mounting plate 143 and mounting plate 144 are joined together, aligning the through holes. Then, the fixing bolt 145 is passed through the through holes in mounting plate 144 and mounting plate 143, and tightened with the nut 146. This allows the semi-circular clamping plate 142 and semi-circular clamping plate 141 to be completely fitted onto the outer wall of the pumping pipe 11. Simultaneously, the knob 1414 on one side of the top upright plate 1411 of semi-circular clamping plate 141 and semi-circular clamping plate 142 is rotated. This drives the threaded rod 1413 to move closer to the pumping pipe 11 via the threaded connection with the threaded hole 1412, causing the pressure plate 1415 to clamp the pumping pipe 11 using the rubber pad 1419, thereby ensuring... The stability of the semicircular clamp 141 and semicircular clamp 142 is ensured. Simultaneously, the pressure plate 1415 on the semicircular clamp 141, when close to the water pumping pipe 11, allows the vibration sensor 1417 to contact the water pumping pipe 11, thereby detecting and measuring the vibration frequency generated by the water pumping pipe 11 under normal conditions. If the vibration frequency changes, it is transmitted to the wireless acquisition unit 15 via the wire 1418. The wireless acquisition unit 15 then sends the electrical signal to the RTU telemetry terminal 16 using the signal transmission module. The RTU telemetry terminal 16 can then use the signal antenna 161 to send a vibration warning signal, quickly notifying maintenance personnel. The battery 22 inside the control cabin 2 is used for storage. The electrical energy converted by pole 17, the circuit breaker 23 can protect the circuit from overload and automatically cut off the power supply, the meter 24 is used to check the power consumption of the electronic equipment in the well monitoring box 1, the current transformer 25 can convert the large current in the primary circuit into a smaller standard current for use by the secondary equipment, the measurement and control terminal 26 is used to process and send the information data of the electromagnetic flow meter 12, the solar controller 28 is responsible for accurately adjusting the charging voltage and current according to the battery type and status to avoid overcharging of the battery 22, and at the same time, it can also effectively adjust the discharge voltage to prevent the battery 22 from over-discharging, and the wiring terminal 27 facilitates the connection of the wires of various electronic components in the control compartment 2.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
