Ecological protection control device based on thermal expansion and contraction of gas

Abstract

The invention discloses an ecological protection control device based on thermal expansion and contraction of gas, and relates to the technical field of ecological environmental protection. The deviceincludes a mounting base, wherein two No. 1 magnetic blocks which are mutually symmetrical are fixedly connected to the right inner wall of the mounting base, and buffer blocks are movably connectedto the right inner wall of the mounting base. According to the ecological protection control device based on thermal expansion and contraction of gas, a part of energy in light is absorbed and transferred to a graphene sheet through heat transfer of a heat conduction column when a solar sheet is irradiated by light through cooperative use of the solar sheet and the graphene sheet, the time for absorbing specified heat depends on the light intensity when the light heat reaches a certain level, therefore, air in the inner cavity of the mounting base is heated, and expands, a piston plate is moved to the right, a No. 1 contact point makes contact with a No. 2 contact point, and an irrigation device is started to irrigate a green belt, so that a control effect is achieved according to the light intensity, irrigation of the green belt is ensured effectively, and the water resource is also saved.

Description

technical field [0001] The invention relates to the technical field of ecological environment protection, in particular to an ecological protection control device based on gas 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 in use, it is either timed watering or...

AI Technical Summary

Problems solved by technology

[0003] However, when the current irrigation control device is in use, it is either timed watering or manual control, and the timed watering method is more wasteful 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
