Description

Technical Field

[0001] This invention relates to the field of air compressor technology, specifically to an energy-saving air compressor based on dual-drive operation. Background Technology

[0002] An air compressor is a device that converts mechanical energy into gas pressure energy, and it is an indispensable power source in most industrial settings.

[0003] Chinese patent discloses "an air compressor for vehicles", with publication (announcement) number "CN106246555B". This patent mainly uses an oil-gas separator to effectively separate oil and gas, reducing the oil content of the compressed air output from the oil-gas separator to the oil-gas filter, thereby extending the service life of the oil-gas filter and reducing the operating cost. However, in the application of the above-mentioned air compressor for oil-gas transportation, the output power of the air compressor will increase due to the excessive length of the transportation pipeline or the increase of the transportation distance. This not only significantly increases the load on the air compressor, but also easily causes the output motor to be damaged due to exceeding the rated operating conditions.

[0004] To address the aforementioned issues, we propose an energy-saving air compressor based on dual-drive operation. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an energy-saving air compressor based on dual-drive operation. During gas delivery, when a significant increase in the power of the main output motor is detected, such as due to pipeline blockage or a sudden increase in gas consumption, the auxiliary output structure is automatically activated, switching to a dual-drive collaborative delivery mode. This avoids the single motor from slowing down or stalling due to overload, thereby maintaining stable exhaust pressure. This helps eliminate the impact of gas pressure fluctuations on end-use equipment, ensuring that the flow rate and pressure of the delivered gas always meet process requirements, and improving the consistency of final product quality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving air compressor based on dual-drive operation, comprising a body, the body being composed of an output motor, an auxiliary housing, and a conveying housing, wherein the output end of the output motor is connected to a transmission rod via a coupling assembly, an auxiliary motor is fixedly mounted on the surface of the auxiliary housing near the output motor, and an auxiliary conveying assembly is provided on the output shaft of the auxiliary motor; The auxiliary conveying assembly includes a rotating disk fixedly installed on the output shaft of an auxiliary motor.

A limit ring groove is recessed in the inner wall of the power gear, and a limit ring is fixedly installed on the surface of the rotating disk. A number of limit components are provided on the surface of the limit ring. The coupling assembly includes a first extrusion plate fixedly installed at the output end of the output motor, and a sleeve block slidably installed on the surface of the first extrusion plate. A second extrusion plate is slidably installed on the inner wall of the sleeve block near the first extrusion plate. Several push damping springs are provided between the second extrusion plate and the sleeve block. An actuation component is provided on the surface of the first extrusion plate.

[0007] Furthermore, the surface of the conveying shell is provided with an air intake and an air outlet. An active screw and a driven screw are rotatably mounted on the inner wall of the conveying shell away from the output motor. One end of the active screw extends through into the interior of the auxiliary shell and is fixedly connected to one end of the transmission rod, so that the rotational force of the output motor can be transmitted to the active screw through the coupling assembly and the transmission rod to ensure the compression output effect of the conveying shell.

[0008] Furthermore, the output end of the output motor extends through into the interior of the auxiliary housing, and the output end of the auxiliary motor extends through into the interior of the auxiliary housing, and the output end of the auxiliary motor is rotatably connected to one side of the inner wall of the auxiliary housing.

[0009] Furthermore, the rotating disk is fitted and fixed to the surface of the auxiliary motor, the inner wall of the power gear is fixedly connected to the rod wall of the transmission rod, and the limiting ring is in sliding contact with the inner wall of the limiting ring groove.

[0010] Furthermore, the limiting component includes an ejection groove formed on the surface of the limiting ring, a fixed cylinder is fixedly installed inside the ejection groove, and a movable push block is movably installed on the inner wall of the fixed cylinder, and a push rod is fixedly installed on the surface of the movable push block.

[0011] Furthermore, several of the limiting components are equidistantly distributed on the surface of the limiting ring, and the tilting direction of the ejection groove is circumferentially inclined sequentially relative to the central axis of the limiting ring. The tilting direction of each ejection groove is consistent to drive the internal components to extend outward.

[0012] Furthermore, one end of the push rod extends through to the surface of the fixed cylinder, and a snap-fit ​​cone head is fixedly installed at the end of the push rod away from the fixed cylinder. A number of snap-fit ​​cone blocks are fixedly installed on the inner wall of the limiting ring groove, and the number of snap-fit ​​cone blocks are closely distributed on the inner wall of the limiting ring groove.

When the first extrusion plate and the second extrusion plate are relatively displaced, the telescopic rod can slide into the inclined groove and generate displacement relative to the inner wall of the auxiliary housing. The inclined groove is configured to activate the corresponding structure when the output motor is under high load and generates displacement relative to the transmission rod.

[0016] Compared with the prior art, the present invention provides an energy-saving air compressor based on dual-drive operation, which has the following beneficial effects: 1. This device can automatically activate the auxiliary output structure and switch to a dual-drive collaborative conveying mode when a significant increase in the power of the main output motor is detected during gas conveying, such as due to pipeline blockage or a sudden increase in gas consumption. This avoids the single motor from slowing down or stalling due to overload, thereby maintaining stable exhaust pressure. This helps to eliminate the impact of gas pressure fluctuations on the end-use gas equipment, ensuring that the flow rate and pressure of the conveyed gas always meet the process requirements and improving the consistency of the final product quality.

[0018] 3. The device responds to overloads through a mechanical automatic triggering mechanism, without relying on complex electronic sensors, thus avoiding protection failure due to sensor malfunction.

[0019] 4. This device utilizes an auxiliary motor that is only briefly engaged when high power output is required, while the main motor operates independently during normal times. This avoids energy waste caused by long-term parallel operation of the two motors. When the load decreases, the device can automatically disconnect the auxiliary motor and return to the single-machine energy-saving mode, achieving a dynamic balance of "power supply on demand". While ensuring output performance, it can make better use of output energy, thereby achieving the overall energy-saving effect of the device. Attached Figure Description

[0024] The working principle of the above embodiments is as follows: When the device is in use, the output motor 2 starts, and its output end drives the first extrusion plate 501 to rotate. Under the elastic force of the push damping spring 504, the second extrusion plate 503 is pressed on the first extrusion plate 501. The two rotate synchronously, and the sleeve block 502 rotates accordingly, driving the transmission rod 6 to rotate. The transmission rod 6 drives the active screw rod 401 to rotate, and the active screw rod 401 drives the driven screw rod 402 to rotate in the opposite direction, drawing air in from the air inlet, compressing it and discharging it from the air outlet, thus realizing normal compressed air delivery. At this time, the load of the output motor 2 is within the normal range, there is no relative axial displacement between the first extrusion plate 501 and the second extrusion plate 503, the end of the telescopic rod 1002 does not enter the inclined groove 1003, the starting ring 1005 remains in the initial position, the push block 1008 does not press the normally closed self-reset switch 1007, the auxiliary motor 7 is in a stopped state, the power gear 803 rotates freely with the transmission rod 6, and since the limiting ring 805 and the limiting ring groove 804 are in sliding contact, and the snap-fit ​​cone 9041 and the snap-fit ​​cone block 9042 are not engaged, the output shaft of the auxiliary motor 7 does not bear torque, and the auxiliary conveying component 8 does not participate in the drive; When the delivery pipeline is blocked or the gas consumption suddenly increases, the compression resistance inside the delivery shell 4 increases, and the load torque of the active screw 401 increases sharply. This resistance is transmitted to the sleeve block 502 through the transmission rod 6, so that the rotational resistance of the second extrusion disc 503 is greater than the pressing friction of the push damping spring 504. As a result, the second extrusion disc 503 overcomes the elastic force of the push damping spring 504 and will have an axial displacement relative to the first extrusion disc 501. As the second extrusion plate 503 moves axially, the telescopic end of the telescopic rod 1002 fixed on the first extrusion plate 501 gradually slides into the inclined groove 1003 on the surface of the sleeve block 502. The inclined surface of the inclined groove 1003 guides the telescopic rod 1002 to move further in the radial direction, while driving the connecting ring 1004 and the starting ring 1005 to move toward the normally closed self-reset switch 1007. The starting ring 1005 moves the pushing block 1008 to slide along the surface of the connecting block 1006 until the pushing block 1008 presses the normally closed self-reset switch 1007. When the normally closed self-reset switch 1007 is pressed, its internal contacts close, sending a start signal to the control circuit of the auxiliary motor 7. The auxiliary motor 7 is energized and starts, and its output shaft drives the rotating disk 801 to rotate. The rotating disk 801 drives the power gear 803 to rotate through the transmission gear 802. Since the power gear 803 is fixedly connected to the transmission rod 6, the torque of the auxiliary motor 7 is superimposed on the transmission rod 6, and together with the output motor 2, drives the active screw rod 401. At the same time, the rotating disk 801 drives the limiting ring 805 to rotate relative to the limiting ring groove 804 on the inner wall of the power gear 803. Since multiple limiting components 9 are evenly distributed on the surface of the limiting ring 805 and the tilting direction of the ejection groove 901 is consistent, when the limiting ring 805 rotates, the movable push block 903 in the fixed cylinder 902 moves outward under the centrifugal force and the guide action of the groove, and moves the push rod 904, so that the snap-fit ​​cone 9041 extends out and forms a one-way snap-fit ​​with the snap-fit ​​cone block 9042 on the inner wall of the limiting ring groove 804. This snap-fit ​​structure ensures that the power of the auxiliary motor 7 can be continuously and stably transmitted, avoiding slippage. In the dual-drive mode, the main and auxiliary motors share the load, the output torque of the output motor 2 decreases significantly, the second extrusion plate 503 gradually resets under the action of the damping spring 504, the telescopic rod 1002 exits from the inclined groove 1003, and the connecting ring 1004 and the starting ring 1005 return to their initial positions. However, since the normally closed self-reset switch 1007 has the function of starting and stopping the equipment after contact and pressing, the auxiliary conveying component 8 will stop conveying when the equipment resumes normal conveying, thus achieving the rational use of energy.

[0025] After the auxiliary motor 7 stops, the snap cone 9041 retracts under the action of the return spring (shown in the figure) in the fixed cylinder 902, and the limit ring 805 and the limit ring groove 804 return to the free sliding state. At the same time, the normally closed self-reset switch 1007 is opened, and the entire system returns to the initial single motor working mode, waiting for the next overload trigger. In this embodiment, the load change of the output motor 2 is sensed by the axial displacement of the coupling assembly 5, and the auxiliary motor 7 is triggered by the purely mechanical starting assembly 10. This achieves the effect of automatic dual-drive activation when overloaded and single-machine energy-saving operation when normal. This helps to eliminate the impact of gas pressure fluctuations on the end gas-using equipment, ensures that the flow rate and pressure of the delivered gas always meet the process requirements, and improves the consistency of the final product quality.

[0026] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
