Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a detection device applicable to a shunt type oil mist on-off indicator. Background Art

[0002] The shunt type oil mist on-off indicator is mainly used to detect whether there is leakage of lubricating oil or coolant in the equipment, ensuring the safety and reliability of the equipment operation. This kind of indicator is usually installed on industrial machinery, engines and other equipment that require lubrication systems. When there is oil mist leakage in the system, the indicator will give a signal to prompt the operator to check and repair the fault in time to prevent further damage.

[0003] In order to ensure the reliability and accuracy of the shunt type oil mist on-off indicator, it is necessary to conduct strict tests on it. Traditional detection methods may result in inaccurate test results due to environmental factors or other interferences. Therefore, it is of great significance to develop a new detection device to simulate the oil mist environment under actual working conditions to test the sealing performance and functions of the indicator. Content of the Utility Model

Detailed Embodiments

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-5 , a detection device applicable to a split-type oil mist on-off indicator in this embodiment includes a vertical frame 1 and a test water tank 9 placed inside the vertical frame 1. A moving cylinder 2 is installed at the center of the top of the vertical frame 1, a moving switch 6 for controlling the operation of the moving cylinder 2 is installed at the lower left side, a condensing nozzle simulation assembly 10 and a flow regulating valve 11 located below the condensing nozzle simulation assembly 10 are installed on the right side, and pressure regulating valves 7 are installed above both the left and right sides. A piston rod of the moving cylinder 2 is fixed with an inner frame 15 that can extend into the test water tank 9. A fixing mechanism 5 and an oil mist conveying mechanism 8 on the same axis as the fixing mechanism 5 are installed on the inner bottom wall of the inner frame 15 by screws. An outlet of the fixing mechanism 5 is communicated with an inlet of the condensing nozzle simulation assembly 10. The oil mist conveying mechanism 8 is communicated with the flow regulating valve 11 and one of the pressure regulating valves 7. An oil mist on-off indicator 4 is placed in the fixing mechanism 5. An inlet of the oil mist on-off indicator 4 faces an output port of the oil mist conveying mechanism 8. A fastening mechanism 3 for tightly fixing the oil mist on-off indicator 4 is installed on the top of the inner frame 15, and the fastening mechanism 3 is communicated with the other pressure regulating valve 7.

[0019] In the above structure, the oil mist on-off indicator can be limited by the fixing mechanism. The fastening mechanism operates, and in cooperation with the parameters provided by the pressure regulating valve, it is judged whether the oil mist on-off indicator is tightly fixed. The oil mist conveying mechanism operates, and also in cooperation with the pressure regulating valve, seals the inlet of the oil mist on-off indicator. Then, external compressed air enters the oil mist conveying mechanism through the flow regulating valve and is conveyed to the oil mist on-off indicator. The moving switch controls the operation of the moving cylinder, driving the inner frame to move down into the test water tank until the oil mist on-off indicator is immersed in water. The flow regulating valve is used to adjust the flow rate to ensure stable test conditions. The oil mist conveying mechanism starts to work, providing simulated oil mist to the oil mist on-off indicator. The sealing performance of the oil mist on-off indicator is judged by observing the bubbles or water level changes in the test water tank.

[0020] The condensing nozzle simulation assembly consists of a condensing nozzle simulation mechanism and a push-button switch mechanism. Before the oil mist enters the lubrication point, it is also necessary to pass through a component called a "condensing nozzle" to turn the oil mist into oil gas and discharge it to the atmosphere through a dedicated exhaust hole;

[0021] The condensing nozzle simulation mechanism can simulate condensing nozzles with three different diameters. These condensing nozzles of different sizes may be used for oil circuits of different sizes or selected according to the requirements of different working conditions. The condensing nozzle simulation mechanism can change the diameter by replacing or adjusting the internal structure, so as to simulate condensing nozzles of different specifications.

[0022] The push-button switch mechanism is usually used to control the opening and closing of the oil mist delivery. According to the selected diameter of the condensing nozzle, a suitable push-button switch needs to be matched to ensure that the oil mist can be correctly delivered and the sealing performance can be detected through the system.

[0023] Furthermore, as Figures 3-4 , the fixing mechanism 5 includes a base 501 installed on the inner bottom wall of the inner frame 15 by screws. An outlet communicating with the condensing nozzle simulation assembly 10 is provided inside the base 501. When the base 501 is fixed by screws, it extends above the base 501 and a frame plate 503 is fixed. The frame plate 503 is rectangular, and an opening is provided at the top. The opening is adapted to the oil mist on-off indicator 4. Drainage ports 504 are provided on all four sides of the periphery of the frame plate 503. The drainage ports 504 on the front and rear sides are concave-shaped, and the drainage ports 504 on the left and right sides are rectangular. A sealing plate 502 is placed between the base 501 and the frame plate 503. The four sides of the sealing plate 502 extend into the drainage ports 504, and the protruding ends on the front and rear sides of the frame plate 503 can press and fix the sealing plate 502. A through-port communicating with the outlet of the base 501 and the outlet of the oil mist on-off indicator 4 is provided on the sealing plate 502. By placing the base in the designated position, then placing the sealing plate and the frame plate on the base in a stacked manner, and locking the base and the frame plate with screws, the base and the frame plate can clamp the sealing plate. When the oil mist on-off indicator is placed in the opening for positioning, it can also accurately align the outlet of the oil mist on-off indicator with the through-port and the outlet of the base.

[0024] Among them, the fastening mechanism 3 includes a downward-pushing cylinder fixed vertically downward at the top of the inner frame 15. The oil inlet end of the downward-pushing cylinder is communicated with one of the pressure regulating valves 7. A rubber block is fixed to the piston rod of the downward-pushing cylinder above the oil mist on-off indicator 4. When the oil mist on-off indicator is placed in the fixing mechanism, the downward-pushing cylinder operates to drive the rubber block to squeeze downward. Then, according to the pressure regulating valve, it can prevent the cylinder from being overloaded or damaged due to excessive pressure, and can also avoid not providing enough force to complete the task due to too low pressure. Therefore, it can play a role in pressing and limiting the oil mist on-off indicator to prevent it from moving during the detection process.

[0025] At the same time, the oil mist delivery mechanism 8 includes a base frame 801 fixed on the inner bottom wall of the inner frame 15 by screws, and a propulsion cylinder 802 is installed on the base frame 801. The oil inlet end of the propulsion cylinder 802 is connected to another pressure regulating valve 7. The piston rod of the propulsion cylinder 802 is fixed with a delivery head 803 opposite to the inlet of the oil mist on-off indicator 4. The inlet of the delivery head 803 is connected to the outlet of the flow regulating valve 11, and the inlet of the flow regulating valve 11 is connected to the external delivery end. When the oil mist on-off indicator is positioned, the propulsion cylinder cooperates with the pressure regulating valve to drive the delivery head to squeeze the inlet of the oil mist on-off indicator to complete the sealing, and at the same time cooperates with the external delivery end and the flow regulating valve to provide simulated oil mist to the oil mist on-off indicator for detection.

[0026] In addition, slides 14 are fixed on both sides of the inner frame 15, and guide rods 13 are fixed on the inner top wall of the stand 1, which are located on both sides of the inner frame 15 and pass through the slides 14. When the inner frame is driven up and down by the action cylinder, the slides will slide on the guide rods, so the cooperation of the slides and the guide rods can make the inner frame move up and down stably.

[0027] The working principle of the above embodiment is:

[0028] Place the oil mist on-off indicator on the sealing plate and form a limit with the frame plate at the same time. Then push the cylinder down to drive the rubber block to move down and closely fit with the oil mist on-off indicator to complete the downward pressure and fixation. At the same time, push the cylinder to drive the conveying head to squeeze and seal the entrance of the oil mist on-off indicator. Rely on the pressure to seal the entrance and deliver compressed air to the oil mist on-off indicator. Then turn the action switch. The action cylinder drives the inner frame to move down into the test water tank, and lowers the oil mist on-off indicator below the horizontal plane. Press the corresponding switch in the condensation nozzle simulation assembly to observe whether the oil mist on-off indicator is qualified and check the sealing at the same time. Turn the action switch again, return to the initial position and release the fixation. Take out the oil mist on-off indicator to complete the test.
