Description

Technical Field

[0001] This utility model relates to the field of energy storage tube wall thickness detection technology, and more specifically, to an energy storage tube wall thickness uniformity detection device. Background Technology

[0002] As a core component of energy storage equipment (such as the electrolyte storage tube of an energy storage battery or the thermal management conduit of an energy storage system), energy storage tubes are coated with different functional coatings inside and outside the base material tube to provide functions such as heat insulation, corrosion prevention, and resistance to high temperature and high pressure. The uniformity of the wall thickness of the energy storage tube is a key indicator affecting its performance: uneven wall thickness will lead to uneven stress on the energy storage tube (such as easy cracking at thin walls under high pressure), differences in thermal conductivity (slow heat conduction at thick walls), decreased sealing performance (poor sealing gasket fit at wall thickness deviations), and even cause safety accidents such as leakage and thermal runaway of energy storage equipment.

[0003] Chinese patent CN209166299U discloses a novel device for detecting the uniformity of wall thickness in a grooved tee fitting. The device includes a measuring plate and a grooved tee fitting body. By inserting the measuring plate into the fitting body and pulling a limiting block on the measuring plate, the telescopic rod and return spring connected to the limiting block deform. The elastic potential energy of the deformed return spring then drives the limiting block to limit the inner wall of the fitting body. However, in practical use, the following drawbacks exist: The wall thickness is calculated by clamping the fitting with a clamp and recording the clamp's movement distance. The clamp's clamping position is limited, making it impossible to detect the uniformity of wall thickness in deeper energy storage tubes. Furthermore, the clamp method makes it difficult to position the detection device relative to the energy storage tube, easily causing the clamp to tilt during detection and affecting the detection results. Therefore, a device for detecting the uniformity of wall thickness in energy storage tubes is proposed. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As attached Figure 1-3The device for detecting the uniformity of the wall thickness of an energy storage tube, as shown, includes a support cylinder 1. First laser ranging sensors 2 are embedded on both sides of the middle portion of the support cylinder 1. These sensors detect the distance between the support cylinder 1 and the inner wall of the energy storage tube during use. A first support frame 3 is fixedly connected to one end of the support cylinder 1, and a second laser ranging sensor 4 is fixedly connected to one end of the first support frame 3. This sensor detects the distance between one end of the first support frame 3 and the outer wall of the energy storage tube during use. A second support frame 14 is fixedly connected to one end of the support cylinder 1, and a handle 15 is fixedly connected to one side of the second support frame 14. The second support frame 14 and the handle 15 provide support for the support cylinder 1, facilitating its movement and use.

[0025] The first laser rangefinder 2 and the second laser rangefinder 4 are on the same horizontal plane, corresponding to each other. The second laser rangefinder 4 corresponds to the wall of the support cylinder 1. When not in use, the first laser rangefinder 2 and the second laser rangefinder 4 detect the distance between the support cylinder 1 and one end of the first support frame 3. When in use, the first laser rangefinder 2 detects the distance between the support cylinder 1 and the inner wall of the energy storage tube, and the second laser rangefinder 4 detects the distance between the first support frame 3 and the outer surface of the energy storage tube. The wall thickness of the energy storage tube can be obtained by adding or subtracting the values. When the support cylinder 1 and the first support frame 3 move synchronously, the uniformity of the tube wall thickness can be determined by observing the change in the values.

[0026] One side wall of the second support frame 14 is attached to the wall of the first support frame 3. The cross-sectional shape of the second support frame 14 is set as "U". The handle 15 is set on one side of the turntable 7. The second support frame 14 can limit the turntable 7 while supporting the handle 15, making it convenient to use by hand.

[0027] A rod 5 is inserted into one end of the support cylinder 1, and a limiting ring 6 is fitted onto one end of the rod 5. The limiting ring 6 limits the insertion position of the rod 5, facilitating its combination. Multiple toothed grooves 9 are formed on the surface of the rod 5. A turntable 7 is fixedly connected to one end of the rod 5. A fixing bolt 8 is inserted into one side of the turntable 7. Rotating the turntable 7 controls the rotation of the rod 5 inside the support cylinder 1. By rotating the fixing bolt 8, the second support frame 14 at one end of the support cylinder 1 is pressed, which fixes the position of the turntable 7.

[0028] The limiting ring 6 is located on one side of the support cylinder 1, and the turntable 7 is located on one side of the second support frame 14. The limiting ring 6 is embedded in the middle of the corresponding annular groove on the surface of the insertion rod 5. The limiting ring 6 limits one end of the insertion rod 5, and the turntable 7 limits the other end of the insertion rod 5, which is convenient for combination and connection. One end of the fixing bolt 8 is attached to the wall of the second support frame 14. Multiple actuating blocks are fixedly connected to the outer surface of the turntable 7. The actuating blocks facilitate the rotation of the turntable 7. The fixing bolt 8 presses against the second support frame 14, which facilitates the fixation of the position of the turntable 7.

[0029] Movable plates 10 are inserted around both ends of the support cylinder 1. A pressing plate 11 and a limiting plate 13 are fixedly connected to both ends of the movable plates 10. Two ball bearings 12 are embedded on one side of the pressing plate 11. As the insert rod 5 rotates, it engages with the teeth on one side of the movable plate 10 through the toothed ring groove 9. This allows the movable plates 10 on both sides of the toothed ring groove 9 to move synchronously to opposite sides, thereby controlling the movable plates 10 to drive the pressing plate 11 to press against the inner wall of the energy storage tube until the ball bearings 12 adhere to the wall of the energy storage tube, thus fixing the support cylinder 1 inside the energy storage tube.

[0030] Multiple movable plates 10 are staggered with each other. Every two movable plates 10 are arranged in parallel and form a single support assembly. Every two support assemblies form a positioning assembly and are perpendicular to each other. There are two sets of positioning assemblies, which are respectively set at both ends of the support cylinder 1. Each set of positioning assemblies can support the support cylinder 1 from all sides, improving the placement stability of the support cylinder 1. One side wall of the movable plate 10 is provided with teeth, and the wall of the movable plate 10 meshes with the wall of the toothed ring groove 9. The rotation of the insertion rod 5 can control the movement of the movable plate 10 through the toothed ring groove 9, which is convenient for driving. The side wall of the extrusion plate 11 away from the ball 12 corresponds to the limiting plate 13. The side wall of the extrusion plate 11 near the ball 12 is set with an arc structure. The moving distance of the movable plate 10 is limited by the limiting plate 13, and the ball 12 can easily fit against the inner wall of the energy storage tube without affecting the rotation and movement of the support cylinder 1 inside the energy storage tube.

[0031] It is worth noting that a protective pad is provided at one end of the fixing bolt 8, and the anti-slip pad is in contact with the wall of the second support frame 14. The first support frame 3 is set as an "L" shape, and one end of the wall of the first support frame 3 is parallel to the support cylinder 1.

[0032] Furthermore, an annular groove is axially provided on the inner wall of the threaded hole corresponding to the fixing bolt 8. A nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit with the surface of the fixing bolt 8 at 15°-20°. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing loosening displacement caused by thread springback.

[0033] The working principle of this utility model is as follows: When in use, one end of the support cylinder 1 is inserted into the middle of the energy storage tube, and the turntable 7 is rotated to control the moving plate 10 to drive the extrusion plate 11 to move around the support cylinder 1, so that the wall of the ball 12 fits against the inner wall of the energy storage tube, and the support cylinder 1 can be fixed in the middle of the energy storage tube.

[0034] At this time, the first laser ranging sensor 2 and the second laser ranging sensor 4 are controlled by the operation panel to start detecting the distance between the support cylinder 1 and the inner wall of the energy storage tube, and the distance between the first support frame 3 and the outer wall of the energy storage tube. The wall thickness of the energy storage tube can be obtained by subtracting the detected values ​​on both sides from the distance value between the first support frame 3 and the support cylinder 1.

[0035] By holding the lever 15, the support cylinder 1 and the first support frame 3 can be moved or rotated synchronously inside and outside the pipeline. The uniformity of the energy storage tube wall thickness can be obtained by observing the numerical change range displayed on the operation panel, which is convenient for testing.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
