Straight-through type vacuum glass solar heat collecting tube

Abstract

The invention relates to the technical field of water heaters, and discloses a straight-through type vacuum glass solar heat collecting tube which comprises an outer tube limiting mechanism. The outer tube limiting mechanism comprises a fixing frame; when a handle swings, a disc is driven to rotate, so that an inner-layer tube is automatically clamped and limited by linkage of an inner brake plate, the stability of the inner-layer tube during heat sealing is guaranteed, and the situation that the inner-layer tube is difficult to fix is avoided; a fixed magnet drives an outer brake plate to approach to an outer-layer tube after being electrified, so that the outer-layer tube is automatically limited while the inner-layer tube is limited, the inner-layer tube and the outer-layer tube are ensured to be concentrically arranged, and machining is more convenient; and through cooperative use of a moving block, a touch plate and a sliding block, when the handle moves, the moving block is driven to synchronously move and finally clamped with a groove, so that a heating gun automatically heats to seal the tube, a special-shaped disc is triggered to rotate, clamping is finally lost, and the heating gun is ensured to conduct heating isochronously to conduct heat sealing.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a straight-through vacuum glass solar heat collection tube. Background technique [0002] With the rapid development of modern society and economy, human beings demand more and more energy. Solar energy is an inexhaustible clean energy with a huge amount of resources. conversion device. [0003] Solar water heaters mainly use heat collecting tubes to collect heat. The solar heat collecting tubes are generally divided into inner tubes and outer tubes. The nozzles of the inner tubes and outer tubes are sealed together, and then the solar tubes are vacuumed to create a vacuum In order to facilitate the sealing of solar collector tubes, thermal melting is generally used for heat sealing. However, when the existing devices are heat sealed, there may be problems that the positioning of the inner tube and the outer tube is not uniform and the preheating time cannot be controlled....

[0003] Solar water heaters mainly use heat collecting tubes to collect heat. The solar heat collecting tubes are generally divided into inner tubes and outer tubes. The nozzles of the inner tubes and outer tubes are sealed together, and then the solar tubes are vacuumed to create a vacuum In order to facilitate the sealing of solar collector tubes, thermal melting is generally used for heat sealing. However, when the existing devices are heat sealed, there may be problems that the positioning of the inner tube and the outer tube is not uniform and the preheating time cannot be controlled. , thus negatively impacting the production of solar

[0004] Aiming at the deficiencies of the prior art, the present invention provides a straight-through vacuum glass solar collector tube, which has the advantages of uniform positioning and isochronous preheating, and solves the problem of non-uniform positioning and preheating time during the production and processing of existing solar energy. The uncontrollable problem ensures that when the device is used for operation, the inner tube and the outer tube can be automatically positioned, and at the same time, automatic preheating is performed after positioning, and the preheating time is kept consistent, so the success rate of heating tube production is improved. , to avoid the position inclination affecting the heat sealing effect of the water heater, and increase the intelligence of the device when it is used
