Description

Technical Field

[0001] This utility model relates to the technical field of liquid level monitoring devices, specifically to a lubricating oil level monitoring device for air compressors. Background Technology

[0002] During the operation of an air compressor, the lubricating oil in the tank is gradually consumed. Traditionally, operators need to periodically stop the machine and manually open the top cover of the tank to visually check the internal lubricating oil level. This method has significant drawbacks: firstly, it cannot provide real-time information on lubricating oil consumption, potentially leading to poor lubrication due to delayed replenishment, affecting air compressor performance or even causing damage; secondly, the refilling process relies on experience and lacks precise full-oil indication, easily resulting in overfilling or underfilling. Therefore, there is an urgent need for a device that can monitor the air compressor lubricating oil level in real-time and intuitively, and clearly indicate the refilling status. Utility Model Content

[0003] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an air compressor lubricating oil level monitoring device to solve the aforementioned problems.

[0004] Technical solution To achieve the above-mentioned objective, this utility model provides the following technical solution: an air compressor lubricating oil level monitoring device, including an air compressor body, an oil tank and a threaded cover for the oil tank installed on the air compressor body, a rectangular box installed on the side of the oil tank, a fixed pulley fixedly installed inside the rectangular box, a traction rope slidably connected to the fixed pulley, one end of the traction rope being connected to a resistance changing structure, and the other end passing through the rectangular box and the oil tank and extending into the interior of the oil tank and being connected to a floating block; The resistance changing structure includes: a rheostat located inside a rectangular box, a second guide plate located on one side of the rheostat and one end of the traction rope fixed to the first guide plate. The weight of the first guide piece is less than that of the floating block.

[0005] Furthermore, the second guide plate has the same length as the rheostat, and a round rod is sleeved on the outer surface of the first guide plate, with the round rod fixedly installed inside the rectangular box.

[0006] Furthermore, one side of the rectangular box is provided with scale lines, and this side is the visible side.

[0007] Furthermore, a small light bulb is provided at the top of the rectangular box, and a mounting groove is provided on one side of the small light bulb.

[0008] Furthermore, there are two fixed pulleys, and the two fixed pulleys are located on the same horizontal line.

[0009] Furthermore, the rheostat, the second conductive plate, the light bulb, and the mounting slot are connected by cables.

[0010] Beneficial effects Compared with the prior art, this utility model provides an air compressor lubricating oil level monitoring device, which has the following beneficial effects: 1. Through the floating block, traction rope and transmission mechanism, the oil level change inside the tank is converted into the linear movement of the No. 1 guide plate on the outside. The operator can observe the oil level change in real time from the outside without opening the tank, which is convenient and quick.

[0011] The device features a visual window with graduated lines. The pointer-like design of the first guide plate accurately indicates the current oil level, making the oil quantity visible. Simultaneously, the circuit formed by the first guide plate, a rheostat, and the second guide plate controls the brightness of a small light bulb, clearly indicating various states such as normal oil level, low oil level requiring attention, and full fill, significantly improving the intuitiveness and reliability of monitoring.

[0012] During refueling, the brightness of the small light bulb gradually increases and then goes out as the oil level rises, providing the operator with a clear signal to stop refueling when the tank is full. This avoids overfilling or underfilling due to experience-based judgment and ensures the accuracy of the refueling amount.

[0013] Continuous liquid level monitoring and the clear indicator light extinguishing can promptly remind operators to replenish lubricating oil, effectively preventing equipment wear or malfunctions caused by insufficient oil operation, extending the service life of the air compressor, and improving operational safety.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0021] Please see Figures 1-5This utility model proposes an air compressor lubricating oil level monitoring device, including an air compressor body 1, with an oil tank 2 set at the top of the air compressor body 1. When the lubricating oil in the oil tank 2 is consumed, the operator needs to unscrew the cap 3 threaded on the top surface of the oil tank 2 to inject lubricating oil into the inside of the oil tank 2. During the process of injecting lubricating oil, a floating block 13 is set near the bottom of the oil tank 2 and is suspended by a traction rope 11. The floating block 13 has a certain weight and its surface is rounded, so it can rise and fall as the lubricating oil is consumed and added. The traction rope 11 is fixed in position by a fixed pulley 12 located at the top inside the oil tank 2. The traction rope 11 is movably connected to the outer surface of the fixed pulley 12. The other end of the traction rope 11 passes through the oil tank 2 and a rectangular box 6 fixed to one side of the oil tank 2, and extends into the interior of the rectangular box 6. The other end of the traction rope 11 is fixed to a first guide plate 10. The weight of the first guide plate 10 is less than that of the float block 13. Thus, the float block 13 can move up and down between the float block 13 and the first guide plate 10 through the traction rope 11 during the consumption and addition of lubricating oil. In order to enable the first guide plate 10 to move better in the rectangular box 6, a round rod 9 is sleeved on the outer surface of the first guide plate 10. The round rod 9 is fixed inside the rectangular box 6, and the first guide plate 10 can be limited by the round rod 9 to ensure that the first guide plate 10 can move better in the rectangular box 6.

[0022] As lubricating oil is continuously added, the floating block 13 will rise with the increasing volume of lubricating oil. At this time, one side of the first guide plate 10 will contact the outer surface of the rheostat 8 fixed inside the rectangular box 6. Simultaneously, one side of the rectangular box 6 will contact the second guide plate 14 located on one side of the rheostat 8. The second guide plate 14 and the rheostat 8 are of the same length. The small light bulb 4, the second guide plate 14, and the rheostat 8 are connected by a cable (the location is not described in detail). After the first guide plate 10 contacts the surface of the rheostat 8, the small light bulb on the rectangular box 6... Bubble 4 will emit a faint light (the connection between bulb 4, guide plate 14, and rheostat 8 via cable will not be described in detail). As float block 13 rises with the addition of lubricating oil, guide plate 10 will descend along rod 9, making the distance between guide plate 10 and the connecting piece at the end of rheostat 8 shorter. At this time, bulb 4 will become brighter and brighter until guide plate 10 slides to the bottom of rectangular box 6. At this time, bulb 4 will go out, and the operator can determine that the lubricating oil added to oil tank 2 is full. After the lubricating oil is added, the lubricating oil in the oil tank 2 will be continuously consumed during the continuous use of the air compressor body 1. At this time, the floating block 13 will descend as the liquid level drops, and the first guide plate 10 will rise continuously, which will cause the first guide plate 10 to contact the rheostat 8 and the second guide plate 14. At this time, the small light bulb 4 changes from bright to dim. To better facilitate operators' understanding of lubricant consumption, a scale line 7 is provided on one side of the rectangular box 6. This side is visible, and the scale line can be observed through the attached... Figure 4 It can be observed that one side of the first guide plate 10 is triangular. When the first guide plate 10 is rising, the triangular side will be indicated on the scale line 7, so that the operator can understand the specific situation of lubricating oil consumption. When the first guide plate 10 rises to its maximum distance, the first guide plate 10 is no longer in contact with the rheostat 8 and the second guide plate 14. At this time, the small light bulb 4 will go out, and the operator needs to twist the cover 3 to add lubricating oil to the oil tank 2.

[0023] An installation slot 5 is provided on the rectangular box 6, allowing the operator to install and replace the battery inside. The installation slot 5 is connected to the light bulb 4, the rheostat 8, and the second guide plate 14 via cables, ensuring that the light bulb 4 is lit during the contact between the first guide plate 10, the second guide plate 14, and the rheostat 8.

[0024] The above implementation method achieves the following: by using a floating block, traction rope, and transmission mechanism, the oil level change inside the tank is converted into the linear movement of the external No. 1 guide plate. Operators can observe the oil level change in real time from the outside without opening the tank, which is convenient and quick.

[0025] The device features a visual window with graduated lines. The pointer-like design of the first guide plate accurately indicates the current oil level, making the oil quantity visible. Simultaneously, the circuit formed by the first guide plate, a rheostat, and the second guide plate controls the brightness of a small light bulb, clearly indicating various states such as normal oil level, low oil level requiring attention, and full fill, significantly improving the intuitiveness and reliability of monitoring.

[0026] During refueling, the brightness of the small light bulb gradually increases and then goes out as the oil level rises, providing the operator with a clear signal to stop refueling when the tank is full. This avoids overfilling or underfilling due to experience-based judgment and ensures the accuracy of the refueling amount.

[0027] Continuous oil level monitoring and clear low oil level warnings (small light bulb goes out) can promptly remind operators to replenish lubricating oil, effectively preventing equipment wear or failure due to insufficient oil operation, extending the service life of the air compressor, and improving operational safety.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
