Description

Technical Field

[0001] This utility model belongs to the field of equipment maintenance technology, and in particular relates to an auxiliary device for draining oil from a tank. Background Technology

[0002] In the maintenance of mechanical equipment (such as gearboxes and hydraulic systems), it is often necessary to open the drain port located on the side wall of the equipment housing to drain the oil when changing the lubricating oil. Because the drain port is located on a vertical or inclined side wall, the oil is directly affected by gravity when draining, and it is very easy for it to flow down the outer surface of the housing rather than dripping vertically. Operators usually try to place an oil receiving container below to catch the oil, but due to limited space and visibility, the curved surface of the housing, or the uncontrollable direction of oil flow, the oil often cannot flow accurately into the container, resulting in a large amount of oil contaminating the equipment casing, pipelines, and surrounding work area.

[0003] Current technology lacks a dedicated auxiliary tool to effectively handle sidewall oil drainage. General-purpose oil receiving trays or simple guide vanes are difficult to install securely on sidewalls and cannot adapt to changes in the curvature of the tank surface, resulting in poor sealing and oil leakage from installation gaps, thus limiting their leak-proof and drainage effects. Therefore, there is an urgent need for a device that can firmly adhere to the tank sidewall, adaptively conform to curved surfaces, and reliably guide oil flow to solve the problems of oil leakage and environmental pollution during sidewall oil drainage. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides an auxiliary device for draining oil from a tank that can effectively collect and guide the oil flow through the side wall of the tank, and prevent oil leakage and environmental pollution.

[0005] This utility model is implemented as follows: an auxiliary device for draining oil from a box, characterized in that it includes a base, one end of which is embedded with a magnet in the length direction, and the other end of which is integrally connected with an oil-guiding extension; the oil-guiding extension can be bent upward to form an oil-guiding channel.

[0006] More preferably, the base and the oil-guiding extension are integrally molded from flexible rubber or silicone.

[0007] More preferably, the magnet is completely encased in the internal material of the base. More preferably, the base is provided with a magnet mounting groove, the magnet is embedded in the magnet mounting groove, and the outer surface of the magnet is not higher than the groove opening surface of the magnet mounting groove. More preferably, the base can form a U-shaped structure. More preferably, the oil-guiding extension can deform synchronously with the base to form a U-shaped oil-guiding channel adapted to the base.

[0008] More preferably, the oil-guiding extension is provided with a slope from the base outward.

[0009] The advantages and technical effects of this utility model are as follows: The tank oil draining auxiliary device provided by this utility model is designed for side wall oil draining conditions and has the following beneficial effects: Achieving reliable adsorption and directional flow on the side wall: With the built-in magnet, the device can be firmly adsorbed below the oil drain port on the side wall of the iron box, forming a stable installation base; the one-piece molded oil guide extension bends upward to form an oil guide channel, which can effectively intercept the oil flowing down the side wall of the box and change its flow direction, guiding it to the pre-set oil receiving container in front, fundamentally solving the problem of difficult oil flow collection on the side wall.

[0010] Adaptive curved surface sealing prevents side leakage: The base, made of flexible rubber or silicone, and the oil-guiding extension have excellent elastic deformation capabilities, allowing them to closely conform to the side wall surfaces of the enclosure with different curvatures, effectively reducing or eliminating gaps between the device and the enclosure. The design of the magnet being completely covered or flush with the mounting slot further ensures the flatness and sealing of the adsorption surface, significantly reducing the risk of oil leakage from the edge of the contact surface.

[0011] Forming a localized containment structure with high flow guidance efficiency: The base can deform into a U-shaped structure, allowing it to wrap around and adhere to the lower outer side of the oil drain port, forming a localized containment dike. Simultaneously, the outer extension of the oil guide deforms into a corresponding U-shaped oil guiding channel, thereby expanding the receiving area for the oil flow. This ensures that regardless of the direction in which the oil overflows from the drain port diffuses, it can be effectively collected and guided to the outlet, improving the reliability and efficiency of flow guidance.

[0012] Simple in structure, easy to install, and widely applicable: The entire device is integrally molded, with a compact structure, and can be quickly installed and disassembled using magnetic force without tools. Its flexible nature allows it to adapt to various box sidewalls of different shapes and sizes, making it highly versatile. As a dedicated maintenance auxiliary tool, it is inexpensive and easy to promote and use, and can significantly improve the cleanliness and safety of the work site. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0016] Example 1, please refer to Figure 1 and Figure 2 An oil draining auxiliary device for a box includes a base 1, one end of which is embedded with a magnet 2, and the other end of which is integrally connected with an oil-guiding extension 3; the oil-guiding extension 3 can be bent upward to form an oil-guiding channel 4.

[0017] This invention addresses the problem of oil easily flowing along the outer wall of a tank during drainage, polluting the environment. It provides a magnetic flow guiding solution. The core working principle utilizes the magnetic force generated by magnet 2 to quickly and stably attach the entire device to the area directly below the oil drain port on the side wall of the iron tank. When oil drains from the port and flows down the side wall, the upward-bent oil-guiding extension 3 forms a protruding oil-guiding channel, effectively intercepting and carrying the flowing oil. Because the outlet of the oil-guiding channel faces the predetermined oil receiving container, the oil's flow direction is changed by gravity, changing from vertical flow along the tank wall to horizontal or inclined discharge along the oil-guiding channel, thus being precisely guided into the container. This achieves a shift from "passive oil receiving" to "active flow guiding," solving the problem of difficult oil collection from side wall drainage.

[0018] This solution creatively solves the oil collection problem in sidewall draining operations by combining magnetic fixation with a flexible flow-guiding structure. The magnet 2 enables rapid, tool-free installation of the device on the iron casing, providing a stable working foundation. The integrally connected and upwardly bendable oil-guiding extension 3 constitutes a crucial physical flow barrier, effectively intercepting oil flowing along the casing sidewall and guiding it in a predetermined direction. The entire device has a simple structure, but cleverly integrates adsorption fixation and flow direction modification functions, fundamentally changing the disordered state of oil flow on the sidewall and significantly improving the cleanliness and oil recovery rate of the draining operation.

[0019] Further optimization: The base 1 and the oil-guiding extension 3 are integrally molded from flexible rubber or silicone. The use of flexible rubber or silicone for integral molding gives the device excellent flexibility and conformability. This allows the base 1 to fit tightly against the sidewall surfaces of boxes with different curvatures and shapes, adapting to complex equipment outlines and eliminating installation gaps caused by mismatches in rigid components, thereby effectively preventing oil leakage from the device edges. Simultaneously, the material's flexibility ensures that the oil-guiding extension 3 can be easily and repeatedly bent and shaped without fatigue damage, and the integral molding process ensures seamless and secure connections, avoiding the risk of leakage due to cracks at the joints, greatly enhancing the device's sealing reliability, environmental adaptability, and service life.

[0020] Further preferred: The magnet 2 is completely encased in the internal material of the base 1.

[0021] By completely encasing magnet 2 within the flexible material of base 1, the magnet is completely isolated from the external environment. This structure firstly eliminates the possibility of oil corroding the magnet, ensuring long-term magnetic stability. Secondly, it eliminates any assembly gaps between the magnet and the base, which could easily become pathways for oil leakage when installed on a side wall. The encasing design makes the adsorption surface of the device a complete, smooth, flexible plane, allowing for a larger and more uniform contact with the housing surface, resulting in better sealing and adsorption stability—a key design feature for improving leak-proof performance.

[0022] Further preferred embodiment: The base 1 is provided with a magnet mounting groove 11, the magnet 2 is embedded in the magnet mounting groove, and the outer surface of the magnet 2 is not higher than the groove opening surface of the magnet mounting groove.

[0023] This solution provides a mountable magnet fixing method. A magnet mounting slot facilitates precise positioning and installation of magnet 2. The outer surface of magnet 2 must not exceed the surface of the mounting slot opening; the core purpose is to ensure the flatness of the device's adsorption surface. A flat adsorption surface allows for surface contact with the side wall of the housing, maximizing the contact area and thus enhancing the strength of the magnetic adsorption. It also minimizes linear gaps caused by surface unevenness, which can directly lead to oil leakage in side-wall flow scenarios. This design ensures that the magnet is replaceable or optional while also optimizing sealing performance.

[0024] Further optimization: The base 1 can form a U-shaped structure. Enabling the base 1 to form a U-shaped structure is a key improvement in addressing potential radial splashing or diffusion flow from the side drain port. Once the device is in place, the base 1 can be manually bent into a U-shape, transforming it from a simple sheet into a "dam" or "oil receiving trough" surrounding the lower part of the drain port on three sides. This significantly expands the effective oil receiving area, ensuring that oil flowing from the drain port in any direction (left, right, or down) is caught by the U-shaped base 1, effectively collecting diffused oil flows overflowing from multiple points such as screwdrivers and the edge of the oil pan, greatly improving the success rate and reliability of oil capture.

[0025] Further optimization: The oil-guiding extension 3 can deform synchronously with the base 1 to form a U-shaped oil-guiding channel adapted to the base 1. This solution is a synergistic optimization of technical solution 5. It requires that the oil-guiding extension 3 can deform synchronously with the U-shaped base 1 to form a corresponding U-shaped oil-guiding channel. This means that when the base 1 is bent into a U-shaped oil receiving groove, the guiding part also becomes a U-shaped "drainage channel". This U-shaped oil-guiding channel can efficiently collect and guide the oil flow from all directions received by the U-shaped base 1 to a single outlet direction. It avoids the oil from accumulating in the wide oil receiving groove or overflowing from both sides, realizing the orderly guidance from "surface receiving" to "linear collection" and then to "point discharge", making the guiding process more concentrated, efficient and controllable.

[0026] Example 2, please refer to Figure 3 The oil-guiding extension 3 has a ramp 31 extending outward from the base. This outward ramp on the oil-guiding extension 3 is a detailed design detail that optimizes fluid dynamics. This ramp structure ensures that the bottom surface of the oil-guiding channel is not horizontal, but rather has a certain guiding inclination. When oil flows into the oil-guiding channel, under the influence of gravity, it will naturally accelerate its flow along the inclination direction of the ramp (i.e., towards the preset outlet and oil receiving container). This reduces oil residue and resistance within the channel, promotes rapid oil discharge, and avoids the risk of overflow due to excessively slow flow. Simultaneously, the ramp design also facilitates the more thorough emptying of residual oil droplets from the channel after oil discharge, keeping the device relatively clean.

[0027] In summary, this utility model provides a cleverly designed, easy-to-install, and highly adaptable auxiliary device for draining oil from the sidewall of a container. It fundamentally solves the installation problem of sidewalls through magnetic fixation; its flexible integrated structure achieves adaptive sealing and fit with complex curved surfaces, effectively preventing edge leakage; and its bendable oil-guiding extension and formable U-shaped structure successfully transform the disordered downward flow of oil from the sidewall into an ordered, guided, and collected liquid flow. This device significantly improves the cleanliness, oil recovery rate, and operational safety of sidewall draining operations, and is also low-cost, robust, and durable, possessing high practical value and promising prospects for widespread application.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
