Abstract

This invention discloses a test device for detecting coolant leaks in electric vehicle radiators, relating to the field of radiator coolant leak detection technology. It includes a workbench and a fixed base. The fixed base is fixedly installed at the top edge of the workbench. The invention also includes a tensioning component and a ring-shaped leak detection component on the top of the workbench.

If there is a minor damage or leak point on the outside of the hose, the colorimetric agent sprayed onto that area will quickly change color upon contact with the leaked coolant, clearly indicating the leak location.

Description

Technical Field

[0001] This invention relates to the field of radiator coolant leakage detection technology, and more particularly to a test device for detecting radiator coolant leakage in electric vehicles. Background Technology

[0002] A car radiator mainly consists of a radiator core, water tank, inlet pipe, outlet pipe, cooling fan, fan shroud, expansion tank, and connecting hoses. The core is the central heat dissipation component, typically composed of aluminum fins and water pipes, responsible for dissipating the heat generated by the engine coolant. The hoses connect the radiator to the engine, water pump, and other components, ensuring coolant flow; they are an indispensable part of the system.

[0003] Existing technologies for detecting coolant leaks in hoses mainly rely on visual inspection, air pressure testing, or overall immersion in water. These methods generally suffer from problems such as inaccurate positioning, complex operation, and low detection efficiency. In particular, when detecting localized leaks or minor damage to hoses, it is difficult to achieve efficient and automated judgment. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing methods for detecting coolant leaks in hoses mainly rely on visual inspection, air pressure testing, or overall immersion in water. These methods generally suffer from problems such as inaccurate positioning, complex operation, and low detection efficiency. In particular, when detecting localized leaks or minor damage to hoses, it is difficult to achieve efficient and automated judgment. Therefore, this invention proposes a test device for detecting coolant leaks in electric vehicle radiators.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A test device for detecting coolant leakage in an electric vehicle radiator includes a workbench and a fixed base. The fixed base is fixedly installed at the top edge of the workbench, and a tensioning component is installed on the top of the workbench opposite to the fixed base. The tensioning component straightens the radiator hose.

A limit frame is fixedly provided on the side of the movable seat, and arc-shaped grooves are provided on the top of the side of the movable seat and the top of the side of the fixed seat.

[0014] Optionally, the bottom half-ring is fixedly provided with an edge cylinder at one end of the flip shaft.

[0018] Optionally, a driven post is fixedly provided at one end of the balancing rack, and the driven post is inserted into the first transverse groove, the inclined groove, or the second transverse groove.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. This invention features a tensioning assembly and a ring-shaped leak detection assembly on the top of the workbench. The tensioning assembly stretches the automotive radiator hose placed on the workbench, straightening it and effectively avoiding blind spots caused by hose bending or loosening, thus providing a good foundation for subsequent leak detection operations. The ring-shaped leak detection assembly can move smoothly along the outer wall of the straightened hose, uniformly spraying a colorimetric agent onto the hose's outer surface during movement. If a minor tear or leak is found on the hose's exterior, the sprayed colorimetric agent will rapidly change color upon contact with the leaking coolant, clearly indicating the leak location. This structure achieves efficient, intuitive, and automated hose leak detection, significantly improving detection accuracy and operational efficiency, and is particularly suitable for rapid batch testing needs in production lines or maintenance scenarios.

[0021] 2. Since radiators typically have two flexible hoses, this invention also includes a drive opening and closing assembly on the side of the workbench. This assembly controls the simultaneous opening and closing of the two annular leak detection assemblies, allowing for the wrapping and detection of both hoses at once. This saves operation time, significantly improves detection efficiency, and is suitable for batch operations. Before the tensioning assembly tightens the hoses, the bottom of the hoses is temporarily supported to prevent them from bending or sagging, ensuring they are at the appropriate height and angle, thus reducing blind spots. After the tensioning assembly tightens the hoses, the drive opening and closing assembly causes the annular leak detection assemblies to close, wrapping the two hoses. This facilitates subsequent leak detection by the annular leak detection assemblies at various points around the outer wall of the hoses.

[0022] 3. The present invention provides a separation and feeding component on the side of the annular leak detection component. The separation and feeding component can separate the annular leak detection component from the drive opening and closing component after the annular leak detection component has performed leak detection. On the other hand, it can drive the annular leak detection component to flip and enter the soaking tank, which facilitates centralized cleaning of the annular structure or recovery of residual color indicator liquid, prevents nozzle clogging or residual pollution from affecting the next round of detection, and improves the continuity and reliability of equipment operation.

[0023] 4. The present invention has a positioning liquid supply component on the side of the annular leak detection component. The positioning liquid supply component uses a physical self-locking structure to supply colorimetric reagent to the annular leak detection component only after the annular leak detection component is closed. This can effectively prevent the colorimetric reagent from being sprayed accidentally when the annular component is not closed or is not aligned with the hose, avoiding waste of reagent and contamination of equipment. At the same time, it ensures that the spraying process is carried out only in the detection state, improving the pertinence and accuracy of the detection. The physical self-locking structure does not require a complex electrical control system, has a simple structure, high reliability, and is suitable for continuous industrial use.

[0038] Reference Figure 1-11A test device for detecting coolant leakage in an electric vehicle radiator includes a workbench 3 and a fixed base 6. The fixed base 6 is fixedly installed at the top edge of the workbench 3. A tensioning assembly is installed on the top of the workbench 3 opposite to the fixed base 6. The tensioning assembly straightens the radiator hose. The tensioning assembly includes a movable base 4, a tensioning screw 2, and an extension block 41. A central groove 5 is opened in the middle of the top of the workbench 3. The tensioning screw 2 is rotatably connected inside the central groove 5. The extension block 41 is fixedly installed at the bottom of the movable base 4. The extension block 41 is threaded into the outer wall of the tensioning screw 2. A limit frame 1 is fixedly installed on the side of the movable base 4. Arc grooves 42 are opened on the top side of the movable base 4 and the top side of the fixed base 6. The limit frame 1 is used to simply fix the car radiator fan. The arc groove 42 is used to accommodate the hose. A rocker wheel is connected to one end of the tensioning screw 2. The user can rotate the tensioning screw 2 by rocking the rocker wheel, thereby moving the movable base 4 away from the fixed base 6 by an appropriate distance.

[0039] A rear frame 7 is fixedly installed on the rear side of the workbench 3 and the fixed base 6. The rear frame 7 has a transverse groove 71. An extension plate 9 is movably inserted into the transverse groove 71. An immersion tank 10 is fixedly installed on the other side of the extension plate 9. A transverse screw 81 is screwed into the side of the extension plate 9. The two ends of the transverse screw 81 are rotatably connected to the two ends of the transverse groove 71. A transverse motor 8 is fixedly installed at one end of the transverse screw 81. The housing of the transverse motor 8 is fixedly installed on the side of the rear frame 7. When the transverse motor 8 is started, it will drive the immersion tank 10 on the side of the extension plate 9 to move through the transverse screw 81. The bottom of the immersion tank 10 is set in an inverted bucket shape to facilitate the drainage of the immersion tank 10. The immersion tank 10 is filled with an appropriate amount of cleaning solution.

[0040] A fixed folding plate 18 is fixedly installed on the top of the rear side of the soaking tank 10. The other end of the fixed folding plate 18 is fixedly installed on the top of the mounting frame 11. A mounting plate 161 is installed in the gap between the soaking tank 10 and the mounting frame 11. One end of the fixed folding plate 18 protrudes from the top of the mounting plate 161. An annular leak detection component is installed on the top of the mounting plate 161. The annular leak detection component sprays the leak indicator agent evenly on the outer wall of the hose. The annular leak detection component includes a bottom half ring 24, a top half ring 22, and an arc-shaped tube 23. A common shaft 251 is rotatably connected to the side of the mounting plate 161. A lifting plate 25 is fixedly installed at equal intervals on the outer wall of the common shaft 251. A bottom half ring 24 is fixedly installed on the top of the lifting plate 25. Therefore, when the common shaft 251 rotates, it will drive the two bottom half rings 24 to rotate synchronously.

[0041] A rotating shaft 30 is rotatably connected to one end of the bottom half ring 24. The rotating shaft 30 is fixedly installed at one end of the top half ring 22. Arc-shaped tubes 23 are fixedly installed on the inner walls of both the top half ring 22 and the bottom half ring 24. Spray holes 231 are equidistantly arranged on the inner wall of the arc-shaped tubes 23. Both ends of the arc-shaped tubes 23 are closed.

[0042] Two arc-shaped tubes 23 are equipped with liquid supply components on their sides. The liquid supply components include a vertical U-shaped hose 26, a transition tube 27, and a docking cylinder 28. Both ends of the vertical U-shaped hose 26 are fixedly installed at one end of the arc-shaped tube 23. The middle position of the side of the vertical U-shaped hose 26 is fixedly connected to one end of the transition tube 27. The side of the transition tube 27 is fixedly connected to the side of the bottom half-ring 24. The other end of the transition tube 27 is fixedly connected to the side of the docking cylinder 28. A liquid supply pipe 29 is fixedly connected to the side of the docking cylinder 28. The liquid supply pipe 29 is externally connected to the color indicator supply system. The color indicator can be a saturated anhydrous copper sulfate solution. When a leak occurs at a certain point in the hose, the water in the coolant reacts with the saturated anhydrous copper sulfate solution, resulting in a color reaction.

[0043] The docking cylinder 28 is movably inserted into one end of the flipping shaft 30. One end of the flipping shaft 30 is hollow. A docking hole 301 is provided on the side of the flipping shaft 30. An edge cylinder 31 is fixedly installed on one end of the bottom half ring 24. The edge cylinder 31 is sleeved on one end of the flipping shaft 30. A damping bolt 32 is screwed into the outer wall of the edge cylinder 31. The end of the damping bolt 32 contacts the outer wall of one end of the flipping shaft 30. The damping bolt 32 applies a certain damping to the rotation of the flipping shaft 30. When the top half ring 22 rotates around the bottom half ring 24 to a certain extent, the angle of the top half ring 22 will be maintained when the top half ring 22 is not subjected to external force.

[0044] The top of the mounting frame 11 is provided with a drive opening and closing assembly, which controls whether the annular leak detection assembly wraps around the radiator hose. The drive opening and closing assembly includes an opening and closing rack 13, an opening and closing gear 33, a common crossbar 14, and an opening and closing electric push rod 15. The opening and closing electric push rod 15 is vertically fixed at the bottom of the mounting frame 11. The common crossbar 14 is fixedly fixed at the output end of the opening and closing electric push rod 15. The opening and closing rack 13 is fixedly fixed at the top edge of the common crossbar 14. The opening and closing gear 33 is fixedly fixed at one end of the flip shaft 30.

[0045] The opening and closing rack 13 and the opening and closing gear 33 are stably meshed. Auxiliary columns 12 are symmetrically fixed at the bottom of the common crossbar 14. The auxiliary columns 12 are movably inserted into the housing of the mounting frame 11. A micro switch 110 is fixedly installed on the mounting frame 11 directly below the bottom end of the auxiliary column 12. The micro switch 110 is connected to the control circuit of the separation electric push rod 16. The separation electric push rod 16 can only be activated when the micro switch 110 is triggered, so as to prevent the separation electric push rod 16 from being accidentally opened when the top half ring 22 and the bottom half ring 24 are wrapped in the hose.

[0046] A separation and insertion assembly is provided on the side of the mounting frame 11. The separation and insertion assembly drives the annular leak detection assembly to flip and extend into the soaking tank 10. The separation and insertion assembly includes a separation electric push rod 16, a drive plate 17, a leveling gear 21, and a leveling rack 20. The separation electric push rod 16 is fixedly installed on the side of the mounting frame 11. The drive plate 17 is fixedly installed on the top of the side of the mounting frame 11. The top of the drive plate 17 has a first horizontal groove 171, an inclined groove 172, and a second horizontal groove 173 sequentially formed on it. The inclined groove 172 and the second transverse groove 173 are connected end to end. The balancing gear 21 is fixedly installed at the end of the common shaft 251. The bottom of the balancing gear 21 is stably meshed with the balancing rack 20. The side of the balancing rack 20 is set in a T-shape. The balancing rack 20 is movably inserted into the side of the mounting plate 161. The balancing rack 20 is stably meshed at the bottom of the balancing gear 21. One end of the balancing rack 20 is fixedly provided with a driven post 19. The driven post 19 is inserted into the first transverse groove 171, the inclined groove 172, or the second transverse groove 173.

[0047] The specific implementation steps and principles of this invention are as follows:

[0048] When the entire device is in standby mode, the driven column 19 is located inside the second transverse groove 173, and the separation electric push rod 16 is in the retracted state. At this time, the opening and closing gear 13 meshes with the opening and closing gear 33. The starting electric push rod 15 drives the opening and closing gear 13 to move vertically. The opening and closing gear 13 drives the top half ring 22 to flip to one side of the bottom half ring 24 through the opening and closing gear 33. At this time, the docking hole 301 is not connected to the transition tube 27. The worker inserts the cooling fan on one side of the car radiator into the limiting frame 1, puts the cooling head into the fixed seat 6, connects the two hoses to the arc groove 42, and finally manually rotates the tightening screw 2 to move the movable seat 4 away from the fixed seat 6 at an appropriate distance. At this time, the hose is tightened.

[0049] Then, the electric push rod 15 is activated, and the electric push rod 15 retracts. Through the opening and closing gear 13 and the opening and closing gear 33, the top half ring 22 is reset. The top half ring 22 and the bottom half ring 24 merge and wrap around the outer wall of the hose. At this time, the docking hole 301 is aligned with one end of the transition tube 27. The liquid supply system of the external liquid supply tube 29 supplies liquid to the two arc-shaped tubes 23 through the transition tube 27 and the vertical U-shaped hose 26. Finally, the horizontal movement motor 8 is activated, and the horizontal movement motor 8 drives the horizontal movement screw 81 to rotate. The entire arc-shaped tube 23 composed of the top half ring 22 and the bottom half ring 24 is evenly sprayed with colorant along the outer wall of the hose.

[0050] After the hose leak test is completed, the separation electric push rod 16 is in the retracted state. At this time, the opening and closing gear 13 meshes with the opening and closing gear 33. The opening and closing electric push rod 15 is activated, which drives the opening and closing gear 13 to move vertically. The opening and closing gear 13 drives the top half ring 22 to flip to one side of the bottom half ring 24 through the opening and closing gear 33. At this time, the micro switch 110 is triggered, which activates the separation electric push rod 16. The separation electric push rod 16 drives the entire mounting plate 161 to move laterally. On the one hand, the opening and closing gear 13 and the opening and closing gear 33 separate. At the same time, the driven column 19 moves along the second transverse groove 173, the inclined groove 172, and the first transverse groove 171. During this process, the leveling gear 20 drives the leveling gear 21 to flip, thereby driving the bottom half ring 24 and the top half ring 22 on the top of the lifting plate 25 to flip into the soaking tank 10.

[0051] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
