DETAILED DESCRIPTION

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

[0031] like Figure 1-Figure 9 As shown, the intelligent control cabinet of the oil 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. A mounting rod 6 is fixed in the cabinet body 1, and an electrically connected PLC controller 25, a frequency converter 33, a power controller 5, a communication module 26 and an oil and water well intelligent monitoring module 34 are installed on the mounting rod 6.

[0032] The power controller 5 can distribute power to the oil pump, the PLC controller 25 , the frequency converter 33 , the communication module 26 and the oil and water well intelligent monitoring module 34 .

[0033] The cooperation between the PLC controller 25 and the frequency converter 33 can control the oil pump to operate in the industrial frequency mode and the variable frequency mode.

[0034] When the oil pump works continuously in the industrial frequency mode, the working mode of the oil pump 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 oil pump is intermittently pumping in the industrial frequency mode, the oil pump can be operated intermittently at the industrial frequency according to the set time. It is suitable for occasions with large liquid level fluctuations. The intermittent pumping mode can set 24 working frequency bands, and can be started and stopped in each period.

[0036] When the oil pump operates continuously in variable frequency mode, the speed of the oil pump can be adjusted individually, which is suitable for most working conditions and can make the oil pump operate within any range of the designed stroke frequency.

[0037] When the pumping unit is pumping intermittently in variable frequency mode, the pumping unit can be operated at a scheduled time for a total of 24 time periods according to the process requirements, and can be selected to be turned on or off in any combination. When pumping intermittently in variable frequency mode, the operating frequency can be set to adjust the number of strokes.

[0038] In the peak, valley and flat mode of the variable frequency mode, the oil pump can change the working strokes according to the peak and valley electricity price periods stipulated by the state, and in each stroke cycle, the upward frequency, upper dead point frequency, downward frequency and lower dead 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 frequency converter 33 can control the oil pump to work in the program mode. This mode decomposes one stroke into four steps for control, namely, upward, top dead center, downward, and bottom dead center. The operating speed of each position can be set separately to optimize the production process.

[0040] The intelligent monitoring module 34 for oil and water wells can measure the load, displacement, strokes, pump efficiency, oil and water and other parameters of the oil pump. The intelligent monitoring module 34 for oil and water wells cooperates with the PLC controller 25, the frequency converter 33 and the communication module 26 to fully control the oil pump and transmit all parameters remotely to the control terminal.

[0041] The control terminal cooperates with the communication module 26 to send remote control instructions to the PLC controller 25, thereby modifying the working parameters of the pumping unit according to the working conditions of the oil well.

[0054] The guide vanes 32 are all inlaid with constant temperature blocks 8 .

[0055] The adjacent first guide block 20 and the second guide block 29 are movably connected through the telescopic rod 21, the adjacent two second guide blocks 29 are movably connected through the telescopic rod 21, and the adjacent second guide block 29 and the third guide block 30 are movably connected through the telescopic rod 21. Specifically, the adjacent first guide block 20 and the second guide block 29 are provided with a second clearance groove 22 and a third clearance groove 24 on opposite sides, the adjacent two second guide blocks 29 are provided with a second clearance groove 22 and a third clearance groove 24 on opposite sides, the adjacent second guide block 29 and the third guide block 30 are provided with a second clearance groove 22 and a third clearance groove 24 on opposite sides, the adjacent second clearance groove 22 and the third clearance groove 24 constitute a placement groove, the placement groove is provided with a telescopic rod 21, the second clearance groove 22 and the third clearance groove 24 are fixed with a fixed shaft 23, and the two ends of the telescopic rod 21 are rotatably connected with the fixed shaft 23 in the second clearance groove 22 and the third clearance groove 24.

[0056] After the multiple telescopic rods 21 are activated, the first guide block 20 , the third guide block 30 and the guide assembly can be combined into a cylindrical structure outside the fixed rod 7 .

[0057] The first guide block 20 , the third guide block 30 and the guide assembly are combined to form a cylindrical structure outside the fixing rod 7 , and then a plurality of guide blades 32 are spread out in a radial shape outside the cylindrical structure.

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

[0059] When the control cabinet is working, the cabinet door 2 is closed. Figure 7 As shown, after the cabinet door 2 is closed, the first guide block 20, the third guide block 30 and the guide assembly are combined into a cylindrical structure on the inner side of the fixing rod 7. At this time, the arc surface 201 on the outer side of the second guide block 29 fits with the outer edge surface of the fixing column 9.

[0060] Then, the multiple telescopic rods 21 are started, and the multiple second guide blocks 29 and the third guide block 30 move toward the inside of the cabinet 1. When the telescopic rods 21 are fully extended, the first guide block 20, the third guide block 30 and the guide assembly are combined into a cylindrical structure outside 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 start the motor 16 and the thermostatic block 8. The motor 16 drives the fan blades 12 to rotate through the cooperation of the gear 13, the gear ring 14 and the rotating ring 15. When the fan blades 12 rotate, the air outside the cabinet 1 enters the cabinet 1 through the through hole 10 and the air inlet 17.
