Description

Technical Field

[0001] The utility model belongs to the technical field of degassing devices, in particular to a degassing oscillation device. Background Art

[0002] Oscillatory degassing plays a vital role in analyzing dissolved gases in oil-filled electrical equipment in power systems. Oscillatory degassing primarily involves vigorous oscillation of the oil sample under specific conditions using a specialized oscillating device. During this oscillation, dissolved gases in the oil are released, separating the gases from the oil. This method offers advantages in its relative ease of operation, high degassing efficiency, and accurate analysis of the various gas components dissolved in the oil. Analysis of these gases can promptly identify potential faults within electrical equipment, such as partial discharge and overheating. For example, overheating can generate hydrocarbon gases such as methane and ethane in the insulating oil, while discharge can generate gases such as hydrogen and acetylene. Detection and analysis of these gases can determine the type and severity of the fault, enabling appropriate repair measures to prevent further escalation and ensure safe equipment operation.

[0003] For example, the Zhongfen 1081-Ⅱ automatic degassing oscillator in the prior art is mainly used for oscillating degassing during the analysis of dissolved gas in oil-filled electrical equipment in power systems, wherein the motor is directly connected to the small wheel, the small wheel is connected to the large wheel through a belt, the large wheel is connected to the coupling, the coupling is connected to the simplified camshaft, the simplified camshaft is connected to the slider through the eccentric shaft, the up and down movement of the eccentric shaft in the slider groove can drive the slider to move back and forth along the support rod, the slider is connected to the tray through the fixture connection hole, and needle tubes are placed in the tray, up to eight of them, with oil samples in the needle tubes. The left and right reciprocating movement of the slider drives the oil sample to oscillate back and forth to achieve degassing.

[0004] In the above-mentioned prior art, oscillation degassing can be effectively performed, but there are the following problems:

[0005] 1. The eccentric shaft is made of alloy steel, and the slider is made of shock-absorbing and impact-resistant acrylic organic material. The initial fit is high precision, and the eccentric shaft fits tightly against the slider. As the working time increases, the slider is prone to deformation under non-uniform impact motion;

[0006] 2. The temperature during oscillation degassing can reach 50°C, and the acrylic organic material slider is more likely to deform. After the slider is deformed, the pure rolling (line contact) between the slider and the eccentric shaft is changed to point contact or surface contact, which leads to contact stress concentration, accelerated wear and fatigue damage, increased clearance, and increased noise.

[0007] Therefore, how to effectively solve the problems of easy deformation of the slider, wear and fatigue damage of the acceleration device, and excessive noise is a technical problem that needs to be solved urgently. Utility Model Content

[0008] In view of the deficiencies in the above-mentioned background technology, the present invention proposes a degassing oscillation device, which solves the problems of easy deformation of the slider, wear and fatigue damage of the acceleration device, and excessive noise.

[0009] The technical solution of this application is:

[0010] A degassing oscillation device includes a drive unit connected to a bracket, the bracket being provided with a sliding unit connected to a tray, and the eccentric shaft in the sliding unit and the eccentric wheel in the drive unit being fitted together via an elastic component provided in the sliding unit. The elastic component allows the eccentric shaft of the sliding unit to be in close contact with the eccentric wheel of the drive unit, allowing for flexible movement without shaking. With increased use, the device maintains its initial state without any change in the fit clearance, preventing any increase in device noise, and effectively reducing noise. Both the eccentric shaft and the eccentric wheel can be made of alloy steel, ensuring pure rolling (line contact). The contact line length is moderate, ensuring both load requirements and reduced friction.

[0011] Furthermore, the driving unit includes a connecting rod connected to the motor, the connecting rod and the eccentric wheel are interference fit, and the eccentric wheel rotates along with the connecting rod.

[0012] Furthermore, a limiting frame is provided on the outer periphery of the eccentric wheel, and the outer wall of the eccentric shaft fits with the inner wall of the limiting frame.

[0013] Furthermore, one end of the eccentric shaft is plugged into the slider, and the other end of the eccentric shaft is provided with a rounded step, the outer wall of which is in contact with the inner wall of the limit frame, and the tray is connected to the slider. The outer surface of the rounded step contacts the inner wall of the limit frame, and the eccentric shaft is tightly attached to the eccentric wheel without any material restrictions, and the fitting clearance does not change.

[0014] Furthermore, the eccentric shaft is cylindrical.

[0015] Furthermore, the top and bottom of the slider are provided with a clearance groove, and the support rod passes through the ear plates at both ends of the clearance groove and is connected to the bracket, shortening the clearance fitting surface between the support rod and the slider, reducing the fitting friction time between the support rod and the slider, and playing a significant noise reduction role.

[0016] Furthermore, the support rod is arranged horizontally, and the slider reciprocates left and right along the support rod.

[0017] Furthermore, at least two support rods are provided to enhance the stability of the slider performing reciprocating motion.

[0018] Furthermore, the elastic component includes a spring arranged on the support rod, and the spring is pressed between the bracket and the slider. The spring enables the sliding unit and the driving unit to always maintain contact and perform eccentric reciprocating motion. At the same time, the spring also mitigates the stroke-type reciprocating motion, effectively playing a role in shock absorption and noise reduction. It mitigates the stroke-type reciprocating motion and plays a significant role in shock absorption and noise reduction.

[0019] Furthermore, grease is provided between the eccentric shaft and the eccentric wheel, thereby further reducing noise.

[0020] The specific beneficial effects of the utility model include:

[0021] 1. The utility model uses an elastic component to make the eccentric shaft of the sliding unit close to the eccentric wheel of the driving unit, so that it can move flexibly without shaking. As the number of uses increases, it can maintain its initial state without changes in the fitting clearance, which will not cause the device to become noisy, and effectively play a role in noise reduction;

[0022] 2. Both the eccentric shaft and the eccentric wheel can be made of alloy steel, which is not easy to deform and ensures the pure rolling (line contact). The contact line length is moderate, which not only meets the load requirements but also reduces friction.

[0023] 3. The support rod in the present invention is equipped with a spring, which keeps the sliding unit and the driving unit in contact with each other and performs eccentric reciprocating motion. At the same time, the spring also mitigates the stroke-type reciprocating motion, effectively playing a role in shock absorption and noise reduction.

[0024] 4. The utility model shortens the clearance fitting surface between the support rod and the slider, reduces the fitting friction time between the support rod and the slider, and plays an effective noise reduction role. BRIEF DESCRIPTION OF THE DRAWINGS
