Technical Field
[0001] The utility model relates to the technical field of solar vacuum tube detection, and more specifically to a solar water heater vacuum tube sealing detection device. Background Art
[0002] Solar vacuum tubes, solar water heater vacuum tubes are the core components of solar water heaters, known as the "heart" of solar water heaters. The quality of vacuum tubes directly affects the service life and performance of solar water heaters. The rapid development of the solar industry has also driven the development of vacuum tube companies. On the one hand, patented technologies surrounding vacuum tubes are constantly being innovated, and on the other hand, vacuum tube companies and production lines have been increasing like mushrooms in recent years. Solar vacuum tubes need to be tested for sealing during production to ensure product quality and safety.
[0003] For example, the utility model with announcement number CN218237892U discloses a solar water heater vacuum tube sealing detection device. (1) When in use, the positioning plates are moved in opposite directions to compress the spring telescopic rod, and then the vacuum tube body is passed through the limiting hole to insert the vent pipe into the vacuum tube body, and the second sealing ring is inserted into the vacuum tube body for sealing. Then the positioning plates are loosened, and the tension of the spring telescopic rod is affected, so that the positioning plates move relative to each other to drive the protective plate and the outer wall of the vacuum tube body to fit and clamp the limit position. Conversely, the positioning plates can be pulled in opposite directions again to move the protective plate away from the vacuum tube body, and the vacuum tube body and the second sealing ring can be separated to remove the vacuum tube body.
[0004] (2) The motor is started to rotate the worm clockwise or counterclockwise to drive the two worm wheels to rotate, so that the two screws rotate to drive the two adjustment plates to move up and down, so that the support plate moves up and down to drive the vacuum tube body to move upward to the top of the support platform to complete the test, or move downward to insert into the water chamber for testing;
[0005] (3) During the inspection, the lifting assembly inserts the vacuum tube body into the water-containing cavity so that the bottom of the vacuum tube body is placed on the pad. At this time, the vacuum tube body is sealed by the second sealing ring, and the connection between the water-containing cavity and the vacuum tube body is sealed by the first sealing ring. One end of the water pipe is closed through a valve and the other end is connected to the water source, so that water can be passed into the water pipe and then into the four water-containing cavities through four connecting pipes to surround the vacuum tube body. By starting the air pump, gas is drawn into the air pipe and then into the four vacuum tube bodies through four ventilation pipes. At this time, observe whether bubbles are generated in the water, thereby realizing the sealing inspection of the vacuum tube body.
[0006] Regarding the above scheme: The inventor believes that the above reference document moves the positioning plate to compress the spring telescopic rod, and then places the vacuum tube body on the positioning plate. The spring tension drives the positioning plate to clamp the vacuum tube body, and then the vacuum tube body is placed into the water chamber, and gas is pumped into the chamber through an air pump to observe whether there are bubbles, thereby realizing the sealing test. However, due to the elasticity of the spring itself and the heavy vacuum tube body, the clamping is not stable and firm enough, and the positioning plate will block the clamping position, making it difficult to detect the clamping position, resulting in incomplete detection effect.

[0040] The working principle and use process of the utility model are as follows: when using the device, firstly, the solar vacuum tube 26 is placed between the first clamping plate 36 and the second clamping plate 37, and then the threaded rod 32 is rotated to drive the first connecting block 33 and the second connecting block 34 to move in the opposite direction, and at the same time, the first connecting block 33 and the second connecting block 34 will slide on the outer side of the limit rod 35, and drive the first clamping plate 36 and the second clamping plate 37 to move in the opposite direction together, and then the first clamping plate 36 and the second clamping plate 37 will clamp and fix the solar vacuum tube 26, because the first connecting block 33 and the second connecting block 34 are both threadedly connected to the threaded rod 32, the first clamping plate 36 and the second clamping plate 37 are not easy to move, so that the fixation of the solar vacuum tube 26 is more firm and stable;
[0041] After that, the ventilation hose 24 and the first rubber block 25 are inserted into the interior of the solar vacuum tube 26, and then the cylinder 21 is started to drive the air pump 23 and the solar vacuum tube 26 to move downward into the water tank 1 through the fixed plate 22, and then the air pump 23 is started to inject gas into the solar vacuum tube 26 through the ventilation hose 24, and at the same time, the water source inside the water tank 1 is observed to see if there are bubbles, thereby realizing the sealing detection of the solar vacuum tube 26. During the detection, the solar vacuum tube 26 can be rotated, and the solar vacuum tube 26 can be smoothly rotated between the first clamping plate 36 and the second clamping plate 37 through the roller 310, so that the clamped position can be moved out by rotation, so that the clamped position can be detected, and the comprehensive detection of the solar vacuum tube 26 can be realized. At this point, the problem that the clamping is not stable and firm enough due to the elasticity of the spring itself and the heavy vacuum tube body, and the clamping position will be blocked by the positioning plate, making it difficult to detect the clamping position, resulting in incomplete detection effect can be solved.
