[0010] By adopting the above technical solution, the angle of the fan blades can be changed by attracting the magnetic rod, thereby changing the flow direction of hydraulic oil in the hydraulic drive box and thus changing the output to the transmission blades.
[0011] The present invention is further configured such that the hydraulic drive box is divided into left and right fixed shells, and the two fixed shells are fixedly connected by bolts, and a sealing ring is installed between the fixed shells. The connection between the hydraulic drive box and the drive rod and the output shaft is connected by a sealed bearing.
[0012] By adopting the above technical solution, the hydraulic drive box can be easily assembled, and leakage of the hydraulic drive box can be avoided as much as possible.
[0013] The invention is further configured such that multiple sets of heat dissipation fins begin on the outer side of the return pipe, and one opening of each set of return pipes is located on the outer side of the end of the transmission blade, and the opening at the other end of each set of return pipes extends to the outer side of the hydraulic drive box and is aligned with the side of the adjusting fan blade.

[0020] 1. This invention, through the design of a hydraulic drive box, power supply ring, adjusting fan blades, and magnetic suction rod, enables the rotation of the fan blades to drive hydraulic oil to flow within the hydraulic drive box, thereby driving the output shaft and allowing it to output torque to the outside. When the output torque needs to be adjusted, the power supply ring supplies power to the electromagnet, which drives the magnetic suction rod to move. The magnetic suction rod, through the outer toothed plate, drives the adjusting fan blades to rotate, changing the angle of the adjusting fan blades and thus altering the flow direction of the hydraulic oil within the hydraulic drive box. Simultaneously, the solenoid valve is opened, allowing the hydraulic oil to enter the cooling pipe and the fixed ring pipe. This allows for different adjustments to the output at both ends of the motor without stopping the machine, improving efficiency and effectively solving the problem that the output at the two sets of motor output ends cannot be adjusted according to requirements.
[0021] 2. This invention, through the setting of a fixed ring pipe, driven fan blades, and cooling fan blades, enables the power of the hydraulic oil flowing in the fixed ring pipe to be converted into the rotation of the cooling fan blades by the driven fan blades. This causes the cooling fan blades to rotate outside the motor, driving airflow and thus dissipating heat from the motor. This improves the motor's heat dissipation and absorbs the power within the hydraulic oil, reducing power waste and the amount of backflow power. It also reduces the driving force of the hydraulic oil on the transmission blades, effectively solving the problem of inconvenient heat dissipation. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0032] The embodiments of the present invention will now be described.
[0033] A differential speed control device for electromechanical equipment, such as Figures 1 to 8As shown, the device includes a motor 1, with drive rods 101 connected to both ends. Each drive rod 101 has a hydraulic drive box 2 connected to its end. Multiple sets of adjusting fan blades 6 are formed on the outer wall of the drive rods 101, each set located inside the hydraulic drive box 2. The adjusting fan blades 6 are rotatably connected to the drive rods 101 via a transmission mechanism. The transmission mechanism includes an electromagnet 103 and a magnetic rod 7. Multiple sets of toothed plates 702 are formed on the outer wall of the magnetic rod 7. A transmission rod 601 is connected inside each set of adjusting fan blades 6. The transmission rod 601 extends into the drive rod 101 and is connected to a transmission gear 602. The transmission rod 601 transmits power through the transmission gear 602 and the toothed plates 702. The magnetic rod 7 is connected to the drive rod 101. A limit plate 701 is connected to the end of the magnetic rod 7 near the electromagnet 103. A magnet 703 is installed between the magnetic rod 7 and the electromagnet 103, allowing the position of the magnetic rod 7 to be adjusted by magnetic force. This, in turn, drives the adjusting fan blade 6 to rotate via the gear plate 702 and the transmission gear 602, thus changing the direction of the hydraulic oil driving force when the adjusting fan blade 6 rotates. An output shaft 3 is installed on the side of the hydraulic drive box 2 away from the drive rod 101, and the end of the output shaft 3 also extends into the interior of the hydraulic drive box 2, where multiple sets of transmission blades 301 are installed. The transmission blades 301 are aligned with the adjusting fan blade 6, enabling... The hydraulic drive box 2 is equipped with multiple sets of return pipes 201 on its outer wall. Multiple sets of heat dissipation fins 202 extend from the outer side of each return pipe 201. One opening of each return pipe 201 is located on the outer side of the end of the transmission blade 301, while the other opening extends to the outer side of the hydraulic drive box 2, aligning with the side of the adjusting fan blade 6. This allows the hydraulic oil to circulate within the hydraulic drive box 2 and dissipate heat through the heat dissipation fins 202. Cooling pipes 5 are connected to both the top and bottom of the hydraulic drive box 2. These cooling pipes 5 are connected to a fixed ring pipe 501 via a pipe, and the fixed ring pipe 501 is fitted with... On the outside of the motor 1, a number of cooling fan blades 504 are installed near the inner wall of the motor 1 in the fixed ring tube 501. The cooling fan blades 504 are aligned with the outer wall of the motor 1. The ends of the cooling fan blades 504 extend into the interior of the fixed ring tube 501, and the output end of the cooling fan blades 504 is connected to a driven fan blade 505. Hydraulic oil flowing in the fixed ring tube 501 drives the driven fan blade 505 to rotate. A connecting pipe 503 is connected to the side of the fixed ring tube 501, and the connecting pipe 503 is connected to the return pipe 201. The cooling fan blades 504 can be driven by the hydraulic oil flowing in the fixed ring tube 501, thereby causing the cooling fan blades 504 to drive the airflow, thereby cooling the motor 1.
[0034] Please see Figure 4 and Figure 5A power supply ring 4 is sleeved on the outer side of the drive rod 101. The power supply ring 4 is connected to an external power source. An output ring 401 is installed on the inner wall of the power supply ring 4. A conductive ring 102 is installed on the outer wall of the drive rod 101. The conductive ring 102 is connected to the output ring 401. The conductive ring 102 is connected to the transmission mechanism through a wire, which can conveniently supply power to the transmission mechanism and enable the transmission mechanism to operate normally.
[0035] Please see Figure 4 The hydraulic drive box 2 is divided into two sets of fixed shells, left and right, and the two sets of fixed shells are fixedly connected by bolts. A sealing ring is installed between the fixed shells. The connection between the hydraulic drive box 2 and the drive rod 101 and the output shaft 3 is connected by a sealed bearing, which can facilitate the installation of the hydraulic drive box 2 and reduce the leakage of hydraulic oil in the hydraulic drive box 2.
[0036] Please see Figure 2 and Figure 6 The cooling pipe 5 is equipped with a solenoid valve 502. A set of fixed ring pipes 501 has an oil inlet at the top. A support frame is installed on the inner wall of the fixed ring pipes 501. The fixed ring pipes 501 are engaged with the motor 1 through the support frame, which can control the flow of hydraulic oil and fix the motor 1 through the support frame.
[0037] The working principle of this invention is as follows: When using the device, firstly, the device is assembled. One half of the hydraulic drive box 2 is installed on the outside of the drive rod 101. Then, multiple sets of adjusting fan blades 6 are installed on the outside of the drive rod 101, and the multiple sets of adjusting fan blades 6 are limited by the magnetic suction rod 7. The magnet 703 inside the magnetic suction rod 7 is aligned with the electromagnet 103. The other half of the hydraulic drive box 2 is sleeved with the output shaft 3, and the hydraulic drive box 2 is merged. The adjusting fan blades 6 are aligned with the transmission blades 301 and fixed by bolts and sealed by sealing rings. Multiple sets of cooling pipes 5 are installed on the outside of the hydraulic drive box 2. The fixing ring pipe 501 is installed on the outside of the motor 1 and connected to the fixing ring pipe 501 through the cooling pipe 5. The cooling pipe is connected to the return pipe 201 through the connecting pipe 503. Finally, the transmission oil is injected into the hydraulic drive box 2 through the oil injection port to complete the assembly of the device.
[0038] When using motor 1, starting motor 1 causes the drive rod 101 of motor 1 to rotate multiple sets of adjusting fan blades 6 on the outside. The adjusting fan blades 6 push the hydraulic oil in the hydraulic drive box 2 to flow towards the transmission blades 301, thereby driving the transmission blades 301 to rotate. The transmission blades 301 drive the output shaft 3 to rotate, enabling the device to output torque. The hydraulic oil returns to the outside of the adjusting fan blades 6 through the return pipe 201, thus achieving circulation. When torque adjustment is required, the power supply ring 4 is turned on, and the power is transmitted to the guide through the output ring 401. The conductive ring 102 is powered, and the current passes through the conductive ring 102 and the wires into the electromagnet 103. The electromagnet 103 is activated and generates a magnetic force, which attracts the magnet 703 inside the magnetic suction rod 7, causing the magnetic suction rod 7 to slide within the drive rod 101. The magnetic suction rod 7 drives the multiple sets of toothed plates 702 on the outer side to move. The toothed plates 702 mesh with the transmission gear 602, causing the transmission gear 602 to drive the transmission rod 601 to rotate, thereby adjusting the angle of the adjusting fan blade 6 and changing the hydraulic oil drive in the hydraulic drive box 2. At an angle, the solenoid valve 502 is opened, allowing some of the driving hydraulic oil to enter the fixed ring pipe 501, thereby reducing the drive on the transmission blade 301 and changing the external output drive. The hydraulic oil in the fixed ring pipe 501 flows within the fixed ring pipe 501, driving the driven fan blade 505 to rotate. The driven fan blade 505 drives the cooling fan blade 504 to rotate outside the motor 1, thereby cooling the motor 1 and improving its cooling efficiency. Part of the power output of the motor 1 can be utilized, thus improving the utilization efficiency. The hydraulic oil flowing in the fixed ring pipe 501 returns to the return pipe 201 through the connecting pipe 503. The cooling fins 202 can cool the hydraulic oil, preventing it from overheating. The returned hydraulic oil continues to flow under the drive of the adjusting fan blade 6, driving the transmission blade 301. Thus, it is not necessary to adjust the output efficiency of the motor 1, but only the output at both ends of the motor 1. The extra output power during adjustment is utilized to cool the motor 1, reducing energy loss and improving utilization efficiency.
