The hydraulic motor 40 may be provided on the return line of the main conduit, or on any one of the secondary conduits.

The generator 50 includes a rotor module 51 and a stator module 52. The rotor module 51 is connected with the output shaft 43, and the stator module 52 is used for outputting electric energy. The rotor module 51 can generate a magnetic field, and the output shaft 43 drives the rotor module 51 to rotate, so that the conducting wires of the stator module 52 make a magnetic induction line cutting motion, and a current is generated in the stator module 52.

The utility model provides an insulating arm subassembly, a plurality of support arms 11 are at flexible in-process, it flows to have hydraulic oil in liquid oil pipe 30 and the liquid oil pipe 20 of returning, because hydraulic motor 40 sets up on liquid oil pipe 20 or liquid oil pipe 30 returns, hydraulic oil drive hydraulic motor 40's output shaft 43 rotates, thereby drive the electricity generation of generator 50, hydraulic drive's stability has been guaranteed to hydraulic motor 40's the mode of setting, avoid hydraulic oil drive hydraulic motor 40 and shunt, intermittent type motion and the oil temperature rising problem that the throttle brought, thereby the stability of support arm 11 operation has been guaranteed.

As shown in fig. 3 and 4, in one embodiment of the present application, the rotor module 51 includes a permanent magnet 511 and a conductive wire winding 512, and the conductive wire winding 512 is connected with the stator module 52. As shown in fig. 3, the conductive wire winding 512 may be disposed in parallel with the permanent magnet 511. Alternatively, the conductive wire winding 512 may be disposed in series with the permanent magnet 511 as shown in FIG. 4. At the initial stage of motor driving, since the conductive wire winding 512 has no current, a magnetic field cannot be generated, and the stator module 52 cannot generate current due to rotation of the conductive wire winding, and the current cannot be fed back to the conductive wire winding; in this embodiment, during the rotation of the permanent magnet 511, the permanent magnet 511 drives the stator module 512 to generate a current, and the current is partially supplied to the conductive wire winding 512, so that the conductive wire winding 512 and the permanent magnet 511 jointly generate a magnetic field, so that the stator module 52 generates a current.

After the conductive wire winding 512 is electrified, an electromagnetic field can be generated, the electromagnetic field and the magnetic field generated by the permanent magnet 511 form a total magnetic field, the stator module 52 generates current in the total magnetic field, and the actuating device 100 is driven to execute different actions, particularly the flow of hydraulic oil at the outlet of the actuating device 100 is different in the starting process, so that the rotating speed of the hydraulic motor 40 is unstable, and the current generated by the generator 50 is unstable. The intensity of the magnetic field generated by the conductive wire winding 512 can be changed by changing the current in the conductive wire winding 512, and when the rotating speed of the motor is increased, the current entering the conductive wire winding 512 is reduced, and the current output generated by the generator is reduced; when the motor speed is reduced, the current into the conductive wire winding 512 is increased, increasing the current output generated by the generator, thereby generally ensuring the stability of the current and/or voltage generated in the stator module 52.

In another embodiment of the present application, a rotor module includes: a conductive wire winding and a power supply. The conductive wire winding is connected with the stator module.

After the generator works for a period of time, the generator generates power which can supply power to the conductive wire winding, the power supply does not supply power, the intensity of a magnetic field generated by the conductive wire winding can be changed by changing the magnitude of current in the conductive wire winding, the intensity of the magnetic field generated by the conductive wire winding 512 can be changed by changing the magnitude of current in the conductive wire winding 512, when the rotating speed of the motor is increased, the current entering the conductive wire winding 512 is reduced, and the current output generated by the generator is reduced; when the motor speed is reduced, the current entering the conductive wire winding 512 is increased, and the current output generated by the generator is increased, so that the stability of the current and/or voltage generated in the stator module is ensured.

As shown in fig. 5, in one embodiment of the present application, the insulating arm assembly further comprises: a first on-off valve 71, a second on-off valve 72, and a third on-off valve 73.

A first on-off valve 71 is provided on the pipe for controlling the flow of liquid in the pipe. One end of the second on-off valve 72 is connected to the inlet end of the first on-off valve 71, and the other end is connected to the input end 41 of the hydraulic motor 40. One end of the third switch valve 73 is connected to the liquid outlet end of the first switch valve 71, and the other end is connected to the output end 42 of the hydraulic motor 40. Wherein, the pipeline is a liquid return oil pipe 30 or a liquid supply oil pipe 20.

When the generator 50 is required to generate electricity, the first on-off valve 71 is closed, the second on-off valve 72 and the third on-off valve 73 are opened, the hydraulic oil in the pipeline passes through the hydraulic motor 40, the hydraulic motor 40 inputs mechanical energy to the generator 50, and the generator 50 generates electric energy. On the contrary, when the power generation by the generator 50 is not required, the first on-off valve 71 is opened, the second on-off valve 72 and the third on-off valve 73 are closed, and the hydraulic oil in the pipe cannot pass through the hydraulic motor 40. The operator can control whether the generator 50 generates electricity or not as needed.

As shown in fig. 6, in one embodiment of the present application, the insulating arm assembly further comprises: a connecting device 80. The coupling device 80 is provided on the output shaft and is connected to the generator 50, and the coupling device 80 is movable in the axial direction and the radial direction of the output shaft 43.

Under the condition of inclination, the force applied by gravity is changed, so that the force applied by the output shaft 43 is also changed, and the connecting device 80 is adjusted to ensure that the force applied by the output shaft 43 is uniform.

As shown in fig. 6, in one embodiment of the present application, the insulating arm assembly further comprises: a battery 90.

The battery 90 is connected to the generator 50 for storing and releasing electric energy. When the electric energy generated by the generator 50 exceeds the electric energy required by the electric appliance, the battery 90 stores the part of the electric energy, so that the waste of the energy is avoided. The battery 90 may provide power to a portion of the powered device when the power generated by the generator 50 is insufficient. In addition, the battery can be used as a power supply to supply power to the conductive wire winding.

Several methods for ensuring the output current of the generator 50 is stable are described in detail below with reference to the accompanying drawings:

in one embodiment, as shown in fig. 7, the insulating arm assembly further comprises: a rotational speed sensor 61 and a controller 64. The rotation speed sensor 61 detects the rotation speed of the output shaft 43 and transmits a rotation speed signal.

The controller 64 is connected to the rotational speed sensor 61 and the stator module 52, respectively, and the controller 64 receives a rotational speed signal. When the controller 64 determines that the rotation speed of the output shaft 43 is equal to or higher than the set threshold value based on the rotation speed signal, the controller 64 controls the stator module 52 to reduce the current input to the conductive wire winding 512.

When the controller 64 determines that the rotation speed of the output shaft 43 is equal to or less than the set threshold value based on the rotation speed signal, the controller 64 controls the stator module 52 to increase the current input to the conductive wire winding 512.

The controller 64 determines that the rotation speed of the output shaft 43 is equal to the set threshold value according to the rotation speed signal, and the controller 64 controls the stator module 52 to maintain the current input to the conductive wire winding 512.

In the case where other conditions are constant, the higher the rotation speed of the output shaft 43, the larger the current generated by the generator 50. With other conditions constant, the greater the strength of the magnetic field of the generator 50, the greater the current generated by the generator 50. The current in the conductive wire winding 512 is adjusted by judging whether the rotating speed of the output shaft 43 meets the set threshold value, that is, the intensity of the electromagnetic field is changed, so that the stability of the output voltage of the generator 50 is ensured, and the instability of the output voltage caused by the instability of the hydraulic oil pressure is avoided.

Example two: as shown in fig. 8, the insulating arm assembly further comprises: an electrical signal sensor 62 and a controller 64. The electric signal sensor 62 detects the current and/or voltage output by the generator 50 and transmits a detection signal.

The controller 64 is connected to the electric signal sensor 62 and the stator module 52, and the controller 64 receives the detection signal.

When the controller 64 determines that the current and/or voltage output by the generator 50 is greater than or equal to the set threshold value according to the detection signal, the controller 64 controls the stator module 52 to reduce the current input to the conductive wire winding 512.

When the controller 64 determines that the current and/or voltage output by the generator 50 is less than or equal to the set threshold value based on the detection signal, the controller 64 controls the stator module 52 to increase the current input to the conductive wire winding 512.

The controller 64 determines that the current and/or voltage output by the generator 50 is the same as the set threshold according to the detection signal, and the controller 64 controls the stator module 52 to maintain the current input to the conductive wire winding 512.

With other conditions constant, the greater the strength of the magnetic field of the generator 50, the greater the current generated by the generator 50. The current in the conductive wire winding 512 is adjusted by judging whether the output voltage and/or the current of the generator 50 meet the set threshold value, namely, the intensity of the electromagnetic field is changed, so that the stability of the output voltage of the generator 50 is ensured, and the instability of the output voltage caused by the instability of the hydraulic oil pressure is avoided.

Example three: as shown in fig. 9, the insulating arm assembly further comprises: a flow sensor 63, and a controller 64. The flow sensor 63 detects the flow rate of the liquid at the hydraulic motor 40 and sends a flow rate signal.

The controller 64 is connected to the flow sensor 63 and the stator module 52, respectively, and the controller 64 receives a flow signal. When the controller 64 determines that the fluid flow rate at the hydraulic motor 40 is above the set threshold based on the flow rate signal, the controller 64 controls the stator module 52 to reduce the current input to the conductive wire winding 512.

When the controller 64 determines from the flow signal that the fluid flow at the hydraulic motor 40 is below a set threshold, the controller 64 controls the stator module 52 to increase the current input to the conductive wire winding 512.

The controller 64 determines from the flow signal that the fluid flow at the hydraulic motor 40 is the same as the set threshold, and the controller 64 controls the stator module 52 to maintain the current input to the conductive wire winding 512.

The higher the flow rate passing through the hydraulic motor 40, the higher the rotation speed of the output shaft 43, and in the case where the other conditions are constant, the higher the rotation speed of the output shaft 43, the larger the electric current generated by the generator 50. With other conditions constant, the greater the strength of the magnetic field of the generator 50, the greater the current generated by the generator 50. The current in the conductive wire winding 512 is adjusted by judging whether the output shaft 43 meets the set threshold value, that is, the intensity of the electromagnetic field is changed, so that the stability of the output voltage of the generator 50 is ensured, and the instability of the output voltage caused by the instability of the hydraulic oil pressure is avoided.
