[0002] The energy-saving power supply module for oil pumping units integrates multiple energy-saving technologies and control strategies. It is primarily used to regulate and optimize the power supply of the oil pumping unit to improve energy efficiency and reduce energy costs. The module can dynamically adjust the motor's input voltage and current based on the oil pumping unit's load changes, ensuring that the motor's output power is precisely matched to the load demand, thereby achieving energy savings.

[0003] Existing power modules are connected to a large number of cables during use. However, due to the random placement of the cables, the entire power system looks messy, which is not conducive to daily maintenance and troubleshooting. The lack of the function of distinguishing and fixing the cables makes it easy for multiple cables to get entangled with each other and cause interference, affecting the accuracy and stability of signal transmission and making subsequent wiring inconvenient. At the same time, the power cord is prone to shaking or even falling off during equipment operation.

[0004] Therefore, we proposed a special energy-saving power supply module for oil pumping units with convenient wiring, which can well solve the above problems. Utility Model Content

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a dedicated energy-saving power supply module for an oil pumping unit with convenient wiring, comprising a lower shell, a power supply module body being mounted on the bottom of the inner wall of the lower shell, and an upper shell being disposed above the lower shell;

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the energy-saving power supply module for oil pumping units with convenient wiring adopts a new structural design, the specific contents of which are as follows:

[0016] (1) The multiple power lines on the power module body pass through the through holes on the fixed plate and the lower shell in turn, and then the guide rod is pulled upward to release the limit on the rotating rod, and the rotating rod is rotated, so that the rotating rod drives the active gear to rotate and drives the two racks to move relative to each other. At the same time, the connecting block drives the clamping plate to move and clamps and fixes the power lines passing through the through holes, so that the multiple power lines are separated, avoiding cross interference between the power lines and other wiring harnesses, and at the same time preventing the power lines from shaking or falling off during the operation of the equipment, thereby achieving the purpose of convenient wiring;

[0020] (4) When the power module body needs to be repaired, the electromagnet is first powered off so that it loses its magnetism and no longer attracts the fixed magnet.

The power module body in the lower shell can then be taken out for repair work.

[0021] Furthermore, after the power module body is installed into the lower shell, the block of the upper shell is inserted into the slot of the lower shell, and multiple gear blocks are used to drive the driven gear to rotate. At this time, the two limit plates rotate inward and drive the electromagnet to move to the position of the fixed magnet. At this time, the electromagnet is energized and adsorbed and fixed to the fixed magnet, thereby improving the firmness of the installation of the upper shell and the lower shell.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 7 The utility model provides the following technical solutions: a special energy-saving power supply module for oil pumping units with convenient wiring,

[0032] Example 1: In order to solve the problem that the existing technology lacks the function of distinguishing and fixing cables, which makes it easy for multiple cables to get tangled together and cause interference, thus affecting the accuracy and stability of signal transmission and making subsequent wiring inconvenient, and the power cord is prone to shaking or even falling off during the operation of the device, the following solution is disclosed. Figure 1 and Figure 3-Figure 6 As shown, it includes a lower shell 1, a power module body 3 is installed at the bottom of the inner wall of the lower shell 1, and an upper shell 2 is arranged above the lower shell 1;

[0033] The cam 12 is provided with a plurality of through holes 14 at the top and a plurality of through holes 15 at the bottom, and the plurality of through holes 16 are provided with a plurality of through holes 17 at the top and a plurality of through holes 18 at the bottom.

[0034] The multiple power lines on the power module body 3 pass through the fixed plate 5 and the through hole 12 on the lower shell 1 in turn, and then the staff pulls the guide rod 15 upward to separate the guide rod 15 from the limiting groove 17 in the initial position, releasing the limit on the rotating rod 7. Then the staff rotates the rotating rod 7 in the forward direction, so that the rotating rod 7 drives the active gear 8 to rotate, and drives the two racks 9 to move relative to each other. At the same time, the connecting block 10 drives the clamping plate 11 to move and clamps and fixes the power line passing through the through hole 12, thereby distinguishing the multiple power lines, avoiding cross interference between the power lines and other wiring harnesses, and also avoiding electrical The power line shakes or falls off during the operation of the equipment, and the purpose of facilitating wiring is achieved. Then the staff loosens the guide rod 15, so that the guide rod 15 is reset under the elastic force of the reset spring 16 and inserted into the corresponding limit groove 17, which can limit the rotated rotating rod 7 to prevent it from deflecting during use. Then the power module body 3 will generate heat during operation. At this time, the multiple heat sinks 4 set up can absorb the heat generated by the power module body 3 and dissipate the heat into the air, thereby dissipating the heat of the power module body 3 and avoiding the power module body 3 being affected by excessive temperature.

[0035] Embodiment 2: Different from embodiment 1, this embodiment utilizes the movable plate 6 to rotate to the position below the power cord, and the power cord can be inserted into the groove on the movable plate 6 for locking and fixing, thereby making the power cord on the power module body 3 neat and tidy, which is conducive to daily maintenance and troubleshooting. For details, refer to Figure 1 、 Figure 2 and Figure 7 As shown, the shaft end of the driven gear 19 and the top end of the transmission rod 20 are connected by a bevel gear set. The left side of the lower shell 1 is rotatably connected to the transmission rod 20, and the outer side of the transmission rod 20 is sleeved with movable plates 6 at equal intervals.

[0036] When the upper shell 2 is engaged with the lower shell 1, the driven gear 19 uses the bevel gear set to drive the transmission rod 20 to rotate, so that the movable plate 6 rotates to the position below the power cord. At this time, the staff will sequentially insert multiple power cords into the grooves on the multiple movable plates 6 to engage and fix them, so that the power cords on the power module body 3 are distributed cleanly and neatly, which is conducive to daily maintenance and troubleshooting.

[0037] Example 3: Different from Example 2, this embodiment uses two limit plates 21 to rotate outward, which can facilitate the separation of the upper shell 2 and the lower shell 1, and then facilitate the removal of the power module body 3 in the lower shell 1 for maintenance. Figure 1 、 Figure 2 and Figure 7 As shown, blocks 18 are fixed at equal intervals on the bottom of the upper shell 2, and gear blocks are installed at equal intervals on the sides of the blocks 18. A slot is provided on the top of the lower shell 1 at a position corresponding to the blocks 18. The left and right sides of the lower shell 1 are rotatably connected to driven gears 19 through shafts, and the shaft end of the driven gear 19 is sleeved with a limit plate 21. The driven gear 19 and the multiple gear blocks on the block 18 are meshed and connected. The limit plate 21 is set in an "L" shape. The side of one end of the limit plate 21 is embedded with an electromagnet 13. Fixed magnets 14 are embedded on the left and right sides of the top of the upper shell 2. The positions of the electromagnets 13 and the fixed magnets 14 correspond to each other. The upper shell 2 is connected to the top of the lower shell 1 through the block 18.

[0038] When the power module body 3 needs to be repaired, the staff first cuts off the power to the power module body 3 so that the power module body 3 no longer provides power to the electromagnet 13. At this time, the electromagnet 13 loses its magnetism and is no longer fixed to the fixed magnet 14. Then the staff rotates the two limit plates 21 outward to make the driven gear 19 rotate and drive the block 18 to move upward, and move the upper shell 2 upward to separate it from the lower shell 1, and then take out the power module body 3 in the lower shell 1 and perform maintenance work. When the maintenance is completed, the staff installs the power module body 3 again. Inside the lower shell 1, the block 18 on the upper shell 2 is inserted into the slot of the lower shell 1 for locking and fixing. At the same time, the block 18 uses multiple teeth on the side to drive the driven gear 19 to rotate, thereby causing the two limit plates 21 to rotate inward and drive the electromagnet 13 to move above the fixed magnet 14. After that, the power module body 3 is energized so that the power module body 3 provides electrical energy to the electromagnet 13. At this time, the magnetic poles on the electromagnet 13 are opposite to the magnets on the fixed magnet 14, so that they are adsorbed and fixed, thereby improving the firmness of the installation of the upper shell 2 and the lower shell 1.
