[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0025] Embodiment one:

[0026] In combination with Figures 1-5The core structure of the shown evaporator leak detection device includes a leak detection pool main body 1, which is a cavity structure with a specific shape. A heating rod 2 is precisely and stably arranged in the cavity of the leak detection pool main body 1. The heating rod 2 is made of high-quality heating materials, has high heating efficiency and stable temperature control characteristics, can quickly raise the temperature of the medium in the cavity to a predetermined detection temperature range, and can accurately adjust the temperature according to actual needs through the temperature control system connected thereto, ensuring that the temperature conditions during the detection process are stable and uniform. On the side wall of the leak detection pool main body 1, a start-stop box 3 for controlling the working state of the heating rod 2 is ingeniously arranged. The start-stop box 3 adopts a humanized design concept and is equipped with a clear and intuitive operation panel. The operator can conveniently and accurately set and control the start, stop, and heating power parameters of the heating rod 2 through the buttons or knobs on the panel. At the same time, the start-stop box 3 also integrates a perfect circuit protection device inside, effectively preventing damage to the heating rod 2 and the entire device caused by abnormal current or other electrical faults.

[0027] On one side of the leak detection tank body 1, the lifting assembly 4 is carefully designed and installed, which includes a lifting body 401 made of high-strength metal material, which has enough rigidity and stability to support the weight and force during the lifting process. Bearings 402 are symmetrically and accurately arranged at both ends of the cavity of the lifting body 401, which are selected from high-precision and low-friction coefficient models, which can effectively reduce the friction of the lead screw 403 between them during rotation, ensuring the smoothness and stability of its rotation, prolonging the service life of the component. The thread accuracy of the lead screw 403 is extremely high, and the surface is treated with special wear resistance. Located at the top of the lifting body 401, a drive motor 404 is installed to drive the rotation of the lead screw 403. The drive motor 404 has good power output performance and speed regulation function, which can be flexibly adjusted according to different lifting speed requirements. It is connected to the lead screw 403 through a stable and reliable transmission device. On the lead screw 403, a ball nut seat 405 that cooperates with it is adaptively installed. The ball structure design inside the ball nut seat 405 further reduces friction resistance, improves transmission efficiency and positioning accuracy. The ball nut seat 405 is fixedly provided with an extension piece 406 through a firm connection method. The ball nut seat 405 and the extension piece 406 are fixedly connected through welding, which further enhances the reliability and durability of the connection between the ball nut seat 405 and the extension piece 406, thereby laying a solid foundation for the stable operation of the entire evaporator 6 leak detection device. The extension piece 406 is made of light and strong alloy material, which has good structural strength and anti-deformation ability. The sidewall of the extension piece 406 is symmetrically and reasonably provided with a guide wheel 407. The sidewalls of the cavity of the lifting body 401 are accurately provided with guide grooves 408 matched with the guide wheels 407. The cooperation between them reaches a very high standard. The surface roughness of the groove wall is finely polished to ensure that the guide wheel 407 can tightly fit when rolling in the guide groove 408, without jamming or disengaging. The depth and width of the guide groove 408 are optimized to provide stable support and guidance for the guide wheel 407.

[0028] On the extension 406 of the lifting assembly 4, a storage basket assembly 5 is fixedly arranged, which is mainly composed of a storage basket body 501, the side wall of the storage basket body 501 is composed of a screen, the mesh size of the screen is accurately calculated and selected, which can ensure that the medium can freely pass through the screen and fully contact with the evaporator 6 during detection, realize efficient detection effect, and effectively prevent the evaporator 6 from accidentally sliding out of the storage basket body 501, the inner wall of the storage basket body 501 is relatively provided with a plurality of groups of buckles 502, two groups of buckles 502 located in the same vertical plane are cleverly provided with a partition plate 503, the partition plate 503 can be flexibly installed and removed according to actual detection requirements, the space in the storage basket body 501 can be reasonably divided into a plurality of independent areas, which is convenient for placing and detecting different types or batches of evaporators 6, improves the orderliness and accuracy of detection, a plurality of groups of evaporators 6 can be placed in the storage basket assembly 5 at the same time, which greatly improves the efficiency of single detection and reduces the detection time and labor cost.

[0029] The diameter of the guide wheel 407 in the embodiment and the width of the guide groove 408 maintain a highly precise matching relationship, so that when the guide wheel 407 rolls in the guide groove 408, it can closely fit the groove wall and move smoothly and fluently, without any jamming or shaking phenomenon, which provides an indispensable guarantee for realizing efficient and accurate evaporator 6 leak detection work.

[0030] The specification of the storage basket body 501 in the embodiment is carefully designed to be smaller than the cavity specification of the leak detection pool body 1, and such a difference design can ensure that the storage basket body 501 has enough gap space when entering the cavity of the leak detection pool body 1 in the vertical direction, avoiding collision or friction with the inner wall of the cavity, thereby ensuring smooth in-out operation, so that the entire evaporator leak detection device can efficiently, stably and safely run, meeting various requirements for accurate evaporator 6 leak detection.

[0031] The buckle 502 in the embodiment is specially designed as an elastic buckle, and a rubber anti-slip layer is carefully arranged on the inner wall of the buckle 502. Such elastic buckle 502 can ensure that the partition plate 503 is effectively placed without shaking, providing extremely reliable partition fixing to ensure that the detection work can be carried out smoothly and accurately.

[0032] Working principle: before the evaporator 6 leak detection work, the subsequent connecting pipeline of the evaporator 6 is properly sealed, after preparation, the heating rod 2 is started, the heating power and time of the heating rod 2 are set and controlled through the start-stop box 3 on the side wall of the leak detection pool body 1, so that the heating rod 2 heats the medium in the leak detection pool body 1, the medium is mostly water, as the temperature of the medium gradually rises, its internal pressure and physical properties also change accordingly;

[0033] Then the lifting assembly 4 is started, the driving motor 404 at the top of the lifting main body 401 starts to operate, drives the screw rod 403 to rotate, and the ball nut seat 405 moves linearly along the screw rod 403 under the effective reduction of the friction resistance of the bearing 402, the extension piece 406 fixedly connected with the ball nut seat 405 moves synchronously, and the basket assembly 5 installed on the extension piece 406 also starts to descend. In the descending process, the guide wheels 407 on the side walls of the extension piece 406 roll in the guide grooves 408 on the two side walls of the cavity of the lifting main body 401, the diameters of the guide wheels 407 are accurately matched with the widths of the guide grooves 408, the stability and accuracy of the descent of the basket assembly 5 are effectively ensured, and the basket assembly 5 stably enters the predetermined position in the leak detection pool main body 1 filled with the heated medium;

[0034] When the basket assembly 5 carrying several groups of the evaporators 6 is completely immersed in the heated medium, if the evaporators 6 have a leakage, the gas in the evaporators 6 will leak to the surrounding medium. Since the medium has been heated, bubbles will be generated at the leakage point due to factors such as pressure difference. At this time, the operator can determine whether the evaporators 6 have a defect and the specific leakage position by observing whether bubbles are generated in the medium, the position and quantity of the bubbles and the like.

[0035] After the detection is completed, the driving motor 404 is reversed to drive the ball nut seat 405 to ascend, so that the basket assembly 5 carrying the evaporators 6 ascends and leaves the leak detection pool main body 1, so as to perform subsequent processing operations, such as repairing or replacing the defective evaporators, arranging the next process for the evaporators that pass the detection and the like.
