Landscaping water-saving spray head based on thermal expansion and cold contraction

Abstract

The invention discloses a landscaping water-saving spray head based on thermal expansion and cold contraction. The landscaping water-saving spray head comprises a mounting box, a graphene cylinder isfixedly connected to the rear portion of an inner cavity of the mounting box, a spring is fixedly connected to the circular inner wall face of the graphene cylinder, a switch mechanism is fixedly connected to the front end of the spring, a connecting mechanism is fixedly connected to the front portion of the inner cavity of the mounting box, supporting frames are fixedly connected to the left portion and the right portion of the upper end of the mounting box, the upper ends of the two supporting frames are jointly and fixedly connected with a connecting frame, a solar panel and two heated sheets are fixedly connected to the connecting frames in a clamped mode, heat conducting sheets are movably connected into the two supporting frames in a penetrating and inserting mode, a mounting frame is fixedly connected to the left end of the mounting box, and an electromagnetic valve is fixedly connected into the mounting frame in a clamped mode. According to the landscaping water-saving spray head based on thermal expansion and cold contraction, the effect of controlling according to the illumination intensity is achieved, greening irrigation is effectively guaranteed, and meanwhile water resources are saved.

Description

technical field [0001] The invention relates to the technical field of landscaping equipment, in particular to a water-saving sprinkler head for landscaping based on thermal expansion and cold contraction. Background technique [0002] With the rapid development of human science and technology, human needs for life are also increasing. Therefore, human beings demand more and more resources from nature, resulting in serious damage to the ecology. Due to the increasing awareness of ecological protection in recent years The stronger it is, the more people start to advocate the protection of ecology and artificially cultivate ecology. For example, greening in cities is an important part of ecological reconstruction, and in order to save water, most of them use drip irrigation technology, which can effectively save water resources while ensuring green water sources. . [0003] However, when the current irrigation control device is used, it is either timed watering or manual cont...

AI Technical Summary

Problems solved by technology

[0003] However, when the current irrigation control device is used, it is either timed watering or manual control, and the timed watering method is a waste of water resources, and it is easy to cause the green roots to be rotted by blisters. Water causes the greening to dry out, and most of the water needed for greening is related to the atmospheric temperature and the time of sunlight. When the greening is exposed to sunlight for a long time, it is easy to lack water. At this time, it is necessary to irrigate in time to ensure that the greening will not Dry to death, and none of the current controls can do that
