Description

TECHNICAL FIELD

[0001] The utility model relates to a heat collecting pipe technical field, concretely is a solar heat collecting pipe anti -explosion device. BACKGROUND

[0002] Solar energy collector is a kind of equipment for converting the radiant energy of sun into heat energy. Since solar energy is relatively dispersed, it must be concentrated, so the collector is the key part of various solar energy devices. The solar heat collecting pipe is generally a full-glass vacuum solar heat collecting pipe, which is composed of two concentric circular glass tubes, and a high vacuum is extracted between the inner and outer tube layers. Its shape is like an elongated warm water bottle core. When in use, the solar heat collecting pipe is directly inserted into the water tank of the solar water heater for assembly.

[0003] The Chinese patent with publication number CN114857789A discloses a solar water heater anti-explosion pipe device and a solar water heater thereof. The anti-explosion pipe device includes a cavity assembly and a float assembly. The cavity assembly includes a cavity and a cover. The cavity is arranged inside the end of the vacuum pipe, and the cover is arranged at the opening end of the cavity and is in close contact with it. An upper water hole is formed in the cover, and a lower water hole is formed in the end face of the closed end of the cavity. The float assembly is slidably arranged inside the cavity and cooperates with the upper and lower water holes. The float assembly has a first state and a second state. When in the first state, the float assembly is in close contact with the lower water hole and away from the upper water hole. When in the second state, the float assembly is in close contact with the upper water hole and away from the lower water hole. The present application effectively prevents the vacuum pipe from being damaged by setting the anti-explosion pipe device. When the vacuum pipe is damaged due to external force, the water heater can be used normally without the need for emergency repair.

[0004] However, the above-mentioned technical solution has the following defects: In the above-mentioned solar water heater anti-explosion pipe device, when water is injected into the heat collecting pipe, the cavity assembly needs to be filled first, and then the water is discharged from the lower water hole into the heat collecting pipe. The efficiency of injecting water inward is low and inconvenient to use. UTILITY MODEL CONTENTS
