Description

Technical Field

[0001] This application belongs to the field of liquid extraction technology, specifically relating to a liquid extraction device. Background Technology

[0002] In the railway transportation sector, locomotives, as the core power unit, are the cornerstone of ensuring the efficient and orderly operation of the entire railway transportation network, and their safe and stable operation is the cornerstone. To ensure the safe operation of locomotives, regular maintenance is required, and changing the lubricating oil in the air compressor is an important part of locomotive maintenance.

[0003] In related technologies, operators drain oil through the oil outlet of the air compressor. However, because the oil outlet is located higher than the compressor's base plate, it is difficult to completely empty the oil from the compressor during the draining process, resulting in a large amount of oil remaining inside. This residual oil mixes with new oil, reducing its cleanliness. This unclean oil may fail to provide effective lubrication and cooling to the moving parts during compressor operation, thus affecting the compressor's performance and lifespan. Utility Model Content

[0004] The purpose of this application is to provide a liquid extraction device that can solve the problem in the related art of oil being difficult to drain from the air compressor, resulting in a large amount of oil residue.

[0005] This application provides a liquid extraction device, which includes: Liquid extraction assembly; A liquid extraction tube, the first end of which is connected to the liquid extraction assembly, and the second end of which is used to extend into the interior of the air compressor and contact the bottom plate of the air compressor; A detection element is disposed on the liquid extraction tube and near the second end of the liquid extraction tube. The detection element is used to detect the amount of oil inside the air compressor.

[0006] In this embodiment, the second end of the suction pipe can extend into the air compressor and contact the bottom plate of the air compressor, so that the suction pipe can extract the oil at the bottom of the air compressor, thereby facilitating the extraction of oil accumulated near the bottom plate and reducing the amount of residual oil inside the air compressor.

[0007] Furthermore, by detecting the amount of oil inside the air compressor through the detection element set on the extraction pipe, the oil level inside the air compressor can be fed back in real time during the extraction process. This helps the operator determine whether the oil has been completely extracted, which in turn facilitates the complete extraction of oil from the air compressor. Attached Figure Description

Detailed Implementation

[0009] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0010] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0011] The liquid extraction device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0012] refer to Figures 1-3 The liquid extraction device provided in this application embodiment may include a liquid extraction assembly 100, a liquid extraction tube 200, and a detection element 500.

[0013] Among them, such as Figure 3As shown, the first end of the suction pipe 200 can be connected to the suction assembly 100, and the second end of the suction pipe 200 can be used to extend into the interior of the air compressor and contact the base plate of the air compressor. A detection element 500 can be disposed on the suction pipe 200, and the detection element 500 can be used to detect the oil level inside the air compressor. For example, the second end of the suction pipe 200 can extend into the interior of the air compressor from the oil inlet.

[0014] The detection element 500 can be positioned close to the second end of the liquid extraction pipe 200. This arrangement allows the detection element 500 to extend into the air compressor along with the second end of the liquid extraction pipe 200, so as to detect the amount of oil inside the air compressor.

[0015] In this embodiment, the second end of the extraction pipe 200 can extend into the air compressor and contact the bottom plate of the air compressor. This allows the extraction pipe 200 to draw oil from the bottom of the air compressor, thereby facilitating the removal of oil accumulated near the bottom plate and reducing the amount of residual oil inside the air compressor. Furthermore, the detection element 500 installed on the extraction pipe 200 detects the amount of oil inside the air compressor, providing real-time feedback on the oil level during the extraction process. This helps operators determine whether the oil has been completely extracted, ensuring thorough removal of oil from the air compressor and effectively improving the cleanliness of the oil inside the air compressor. This, in turn, helps guarantee the operating efficiency and safety of the locomotive.

[0016] In addition, by using the pumping component 100 to extract oil, the oil in the air compressor can be extracted in a short time, such as reducing the oil extraction time to 10 minutes, which greatly shortens the extraction time, improves work efficiency, and allows the extraction operation to be carried out by one operator, thus reducing labor costs.

[0017] In an optional embodiment, the liquid extraction assembly 100 may include a liquid extraction pump 110 and a drive module 120. The drive module 120 may be a drive motor, which provides power to the liquid extraction pump 110. Here, the inlet of the liquid extraction pump 110 may be connected to the liquid extraction pipe 200, and the outlet of the liquid extraction pump 110 may be connected to the liquid storage tank 400 described below, so as to be able to extract oil into the liquid storage tank 400.

[0018] In optional embodiments of this application, such as Figure 2As shown, the second end of the extraction pipe 200 can be provided with multiple notches 220. These notches 220 are spaced apart circumferentially along the extraction pipe 200, and are connected to the suction port 210 at the second end of the extraction pipe 200. In this embodiment, multiple notches 220 spaced apart circumferentially and connected to the suction port 210 are provided at the second end of the extraction pipe 200. When the second end of the extraction pipe 200 contacts the base plate of the air compressor, these notches 220 play a crucial "ventilation and flow guiding" role, preventing the base plate from completely sealing the suction port 210. Oil can flow smoothly into the suction port 210 through the notches 220 and then into the interior of the extraction pipe 200. Furthermore, the circumferential distribution of multiple notches 220 effectively forms multiple oil inlets around the second end of the extraction pipe 200, thereby increasing the contact area between the extraction pipe 200 and the oil, and enabling oil to be drawn from different directions, which is beneficial for improving the efficiency and thoroughness of extraction.

[0019] In other embodiments, the second end of the extraction tube 200 may not have a notch 220.

[0020] In an optional embodiment, the detection element 500 may include a camera. Using image recognition technology, the camera can accurately detect the oil level inside the air compressor and the amount of residual oil at different locations on the compressor's base plate. During the extraction process, the operator can monitor the extraction progress in real time based on the images transmitted from the camera and adjust the angle and depth of the second end of the extraction tube 200 within the air compressor to ensure better contact with the oil near the base plate, thus improving the thoroughness of the extraction. Furthermore, the camera can collect information about the internal condition of the air compressor, such as whether there are leaks or impurities inside, allowing the operator to promptly identify and address any issues.

[0021] In other embodiments, the detection element 500 may not include a camera; for example, the detection element 500 may include a liquid level sensor.

[0022] Optionally, the detection element 500 can communicate with the wireless module described below, so that the operator can view the oil level in the air compressor and the pumping operation process in real time from a distance.

[0023] In optional embodiments, such as Figure 1As shown, a fixing tube 600 is provided on the liquid extraction tube 200. The fixing tube 600 extends along the length of the liquid extraction tube 200 and is used to accommodate the wires electrically connected to the detection element 500. In this embodiment, the fixing tube 600 provides a safe space for the wires, isolating them from the outside environment. This effectively avoids problems such as insulation damage and internal core breakage caused by friction and collision, ensuring the integrity of the wires and the stability of the electrical connection. Furthermore, the fixing tube 600 reduces direct contact between the wires and the external environment, reducing the corrosion of the wires by oil, water vapor, etc., which helps extend the service life of the wires and thus ensures the normal operation of the detection element 500.

[0024] In other embodiments, the fixing tube 600 may not be provided on the liquid extraction tube 200.

[0025] Optionally, the fixing tube 600 and the liquid extraction tube 200 can be an integral structure. This design can improve the connection stability between the fixing tube 600 and the liquid extraction tube 200, and can reduce the number of connection structures, thus simplifying the structure of the liquid extraction tube 200. For example, the fixing tube 600 and the liquid extraction tube 200 can be integrally injection molded, which helps to reduce the processing difficulty.

[0026] Of course, the fixed tube 600 and the liquid extraction tube 200 may not be an integral structure.

[0027] In some embodiments, such as Figure 1 As shown, a fixing cover 700 can also be provided on the liquid extraction tube 200. The fixing cover 700 can cover a portion of the liquid extraction tube 200, and an installation space can be formed between the fixing cover 700 and the liquid extraction tube 200. Exemplarily, the liquid extraction device can also include a battery and an image processing module. The battery can be disposed within the installation space and used to power the camera. The image processing module is electrically connected to the battery, and a wire can extend into the installation space and be electrically connected to the image processing module to transmit the acquired image to the image processing module. Here, to prevent oil from entering the fixing cover 700, the fixing tube 600 can extend into the fixing cover 700 and seal with it. Exemplarily, the fixing cover 700 can serve as an operating handle for easy gripping and operation by the operator.

[0028] In optional embodiments, such as Figure 3 As shown, the liquid extraction equipment may also include a filter device 300, and the first end of the extraction pipe 200 can be connected to the extraction assembly 100 through the filter device 300. With this configuration, during the oil extraction process, the filter device 300 filters the oil, preventing impurities in the oil from entering the extraction assembly 100 and causing damage to it. It also improves the cleanliness of the oil, facilitating its recycling.

[0029] Of course, the liquid extraction equipment may also exclude the filtration device 300.

[0030] Optionally, the filtration device 300 may include at least two layers of filter screens, each of which may be arranged sequentially along the direction from the liquid extraction pipe 200 to the liquid extraction assembly 100, and the mesh size of each filter screen gradually decreases along the direction from the liquid extraction pipe 200 to the liquid extraction assembly 100. This arrangement enables multi-stage filtration and improves filtration accuracy.

[0031] Of course, the filter device 300 may also consist of only one filter screen.

[0032] In an optional embodiment, the filter device 300 may further include a magnetic element that can be used to adsorb metallic impurities in the oil to further improve the filtration effect.

[0033] In an optional embodiment, the liquid extraction device may further include a mobile body, on which the liquid extraction component 100 can be mounted. This configuration allows the liquid extraction device to easily reach different work locations, reducing labor costs and intensity, minimizing equipment handling and installation time, and effectively improving work efficiency. For example, the mobile body may include a cabinet and a driving mechanism disposed at the bottom of the cabinet, with the liquid extraction component 100 housed within the cabinet. The driving mechanism may include multiple wheels to move the cabinet. Here, the wheels can be drive wheels to automatically move the cabinet; alternatively, the wheels can be rollers, allowing the operator to manually push the cabinet.

[0034] Of course, the liquid extraction equipment may also not include a moving body.

[0035] Optionally, such as Figure 3 As shown, the liquid extraction device may also include a liquid storage tank 400, which can be connected to the liquid extraction pipe 200 through the liquid extraction component 100, so that the extracted oil can be stored for recycling.

[0036] Of course, the liquid extraction equipment may also exclude the liquid storage tank 400.

[0037] Alternatively, the storage tank 400 can be mounted on the mobile body. This configuration integrates both the storage tank 400 and the extraction component 100 onto the mobile body, allowing the extracted oil to flow directly into the storage tank 400. This eliminates the need for long-distance pipeline transport or manual handling to other storage locations, enabling safe and efficient storage and transportation of oil and reducing the risk of leakage and contamination. Of course, the storage tank 400 may also be mounted independently of the mobile body.

[0038] In some embodiments, the liquid pumping device may further include a liquid filling pipe that can be connected to the outlet of the liquid storage tank 400 so as to fill the liquid in the liquid storage tank 400 into other devices, such as filling the oil in the liquid storage tank 400 into an air compressor through the liquid filling pipe.

[0039] To improve the cleanliness of the oil, a filter can be installed between the storage tank 400 and the liquid filling pipe to further filter the oil.

[0040] Optionally, the mobile unit may be equipped with storage compartments for storing items. These items may include tools such as wrenches and screwdrivers, as well as pipes. This arrangement ensures that operators frequently use these tools and materials during work; the storage compartments on the mobile unit keep these items readily available, eliminating the need to search elsewhere and reducing time wasted searching for items, thus improving work efficiency. In some embodiments, the mobile unit may have multiple storage compartments, each capable of storing different items, allowing for partitioned storage of different items.

[0041] Of course, the mobile device may not need to have a storage compartment.

[0042] In an optional embodiment, the liquid extraction device may further include an electronic control module and a wireless module. The electronic control module is communicatively connected to the liquid extraction component 100 and the detection element 500, and is used to control the liquid extraction component 100. The wireless module can communicate with the electronic control module and can also be used to communicate with electronic devices. In this embodiment, the detection element 500 can feed back the detected oil quantity information in the air compressor to the electronic control module, which can then adjust the operating state of the liquid extraction component 100 in a timely manner based on the feedback information. Furthermore, the electronic control module can precisely adjust the operating parameters of the liquid extraction component 100, such as extraction speed and flow rate, and can adjust the operating state of the liquid extraction component in real time. The wireless module can remotely transmit the operating data of the liquid extraction component 100 collected by the electronic control module and the detection information of the detection element 500 to electronic devices, facilitating remote observation and operation by operators.

[0043] In other embodiments, the liquid extraction device may also exclude the wireless module.

[0044] The liquid extraction device provided in this application embodiment can also be used to extract liquids other than oil, and the liquid extraction device can also be applied to devices other than compressors.

The specific embodiments described above are merely illustrative and not restrictive.
