[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0031] As Figures 1 - 9 shown, the intelligent control cabinet for a pumping unit includes a cabinet body 1, and a plurality of wire holes 27 are opened on the bottom plate of the cabinet body 1. An installation rod 6 is fixed inside the cabinet body 1, and a PLC controller 25, an inverter 33, a power controller 5, a communication module 26, and an oil well intelligent monitoring module 34 which are electrically connected are installed on the installation rod 6.

[0032] The power controller 5 can perform power distribution on the pumping unit, the PLC controller 25, the inverter 33, the communication module 26, and the oil well intelligent monitoring module 34.

[0033] The cooperation between the PLC controller 25 and the inverter 33 can control the pumping unit to work in the power frequency mode and the variable frequency mode.

[0034] When the pumping unit works continuously in the power frequency mode, the working mode of the pumping unit is the same as the conventional working mode, which is suitable for continuous operation with sufficient liquid level and large load displacement.

[0035] When the pumping unit performs intermittent pumping in the power frequency mode, the pumping unit can perform power frequency intermittent operation according to the set time, which is suitable for occasions with large liquid level fluctuations. The intermittent pumping mode can set 24 working frequency bands, and each time period can be started and stopped.

[0036] When the pumping unit works continuously in the variable frequency mode, the pumping unit can be individually speed-regulated, which is suitable for most working conditions, and the pumping unit can work within any range of the designed stroke frequency.

[0037] When the pumping unit performs intermittent pumping in the variable frequency mode, the pumping unit can be run regularly according to process requirements for a total of 24 time periods, and can be respectively selected to be turned on or off, with any combination. When performing intermittent pumping in the variable frequency mode, the running frequency can be set to adjust the stroke frequency.

[0038] In the peak-valley-flat mode of the variable frequency mode, the pumping unit can change the working stroke frequency according to the peak-valley electricity price periods stipulated by the state, and in each stroke cycle, the upward frequency, the upper stop point frequency, the downward frequency, and the lower stop point frequency (can also be set to the same frequency) can be set again to achieve the purpose of optimizing the production process and increasing efficiency and energy saving.

[0039] The cooperation between the PLC controller 25 and the inverter 33 can control the pumping unit to work in the program mode. In this mode, one stroke is decomposed into 4 steps for control: upward, upper stop point, downward, and lower stop point. The running speed at each position can be set separately to optimize the production process.

[0040] The intelligent monitoring module 34 of oil and water wells can measure parameters such as the load, displacement, stroke frequency, pump efficiency, oil and water of the pumping unit. The intelligent monitoring module 34 of oil and water wells cooperates with the PLC controller 25, the frequency converter 33 and the communication module 26 to comprehensively control the pumping unit and transmit all parameters to the control terminal remotely.

[0041] The cooperation between the control terminal and the communication module 26 can send remote control instructions to the PLC controller 25, and then modify the working parameters of the pumping unit according to the working conditions of the oil well.

The two adjacent second diversion blocks 29 are movably connected through a telescopic rod 21. The adjacent second diversion block 29 and third diversion block 30 are movably connected through a telescopic rod 21. Specifically, on the opposite sides of the adjacent first diversion block 20 and second diversion block 29, a second relief groove 22 and a third relief groove 24 are respectively provided. On the opposite sides of the two adjacent second diversion blocks 29, a second relief groove 22 and a third relief groove 24 are respectively provided. On the opposite sides of the adjacent second diversion block 29 and third diversion block 30, a second relief groove 22 and a third relief groove 24 are respectively provided. The adjacent second relief groove 22 and third relief groove 24 form a placement groove. Telescopic rods 21 are placed in the placement grooves. Fixed shafts 23 are fixed in both the second relief groove 22 and the third relief groove 24. The two ends of the telescopic rod 21 are respectively rotatably connected to the fixed shafts 23 in the second relief groove 22 and the third relief groove 24.

[0056] After starting a plurality of telescopic rods 21, the first diversion block 20, third diversion block 30, and the diversion component can enclose a cylindrical structure outside the fixed rod 7.

[0057] After the first diversion block 20, third diversion block 30, and the diversion component enclose a cylindrical structure outside the fixed rod 7, the plurality of diversion vanes 32 are radially spread out on the outside of the cylindrical structure.

[0058] A plurality of first relief grooves 18 are formed on the outer side of the fixed shaft 23 below the rotating ring 15. After the first flow guide block 20, the third flow guide block 30 and the flow guide assembly enclose a cylindrical structure on the outer side of the fixed rod 7, the fixed column 9 is located inside the cylindrical structure, and a plurality of rotating shafts 19 are respectively located in the plurality of first relief grooves 18.

[0059] When the control cabinet is working, the cabinet door 2 is closed. Refer to Figure 7 As shown, after the cabinet door 2 is closed, the first flow guide block 20, the third flow guide block 30 and the flow guide assembly enclose a cylindrical structure on the inner side of the fixed rod 7. At this time, the arc surface 201 on the outer side of the second flow guide block 29 is attached to the outer edge surface of the fixed column 9.

[0060] Then, a plurality of telescopic rods 21 are started, and a plurality of second flow guide blocks 29 and a third flow guide block 30 move towards the inside of the cabinet body 1. When the telescopic rods 21 are fully extended, the first flow guide block 20, the third flow guide block 30 and the flow guide assembly enclose a cylindrical structure on the outer side of the fixed rod 7.

At this time, the cabinet door 2 cannot be opened, and the cabinet door 2 can be effectively stabilized.

[0061] Then, the motor 16 and the constant temperature block 8 are started. The motor 16 drives the fan blade 12 to rotate through the cooperation of the gear 13, the toothed ring 14 and the rotating ring 15. When the fan blade 12 rotates, the air outside the cabinet body 1 enters the cabinet body 1 through the through holes 10 and the air inlet holes 17.

[0062] The plurality of scattered flow guide vanes 32 can disperse the air entering the cabinet body 1, and improve the cooling effect on the inside of the cabinet body 1. When the fan blade 12 rotates and the air outside the cabinet body 1 enters the cabinet body 1, the air inside the cabinet body 1 can be discharged through the exhaust holes 28 at the lower end of the cabinet body 1.

[0063] Start a plurality of telescopic rods 21 to make the plurality of telescopic rods 21 contract. After the first flow guide block 20, the third flow guide block 30 and the flow guide assembly enclose a cylindrical structure on the inner side of the fixed rod 7, the fixed column 9 is located outside the cylindrical structure. At this time, the cabinet door 2 can be opened, and the constant temperature block 8 is blocked by the flow guide vanes 32, which can effectively protect the constant temperature block 8.

[0064] After the cabinet door 2 is in the open state, the first diversion block 20, the third diversion block 30 and the diversion assembly enclose a cylindrical structure outside the fixed rod 7, and then multiple constant temperature blocks 8 can all be exposed, facilitating the replacement of the constant temperature blocks 8.
