Description

The adjustable shielding device for exempting to be exposed to the sun for a long time for the precious flowers in Garden Engineering

Technical field

The utility model belongs to flower planting, gardens corollary apparatus technical field, more particularly, in Garden Engineering Precious flowers exempt from the adjustable shielding device being exposed to the sun for a long time.

Background technology

Currently, the attention with everybody to environment, while being beautification indoor environment, all get used to outer planting pot indoors Plant.In present city, the green plantss of many pottings is either all put at home or in office, but because now all The busy and unprofessional plantation knowledge of people from city's live and work, many plants are often because nobody arranges or will not beat It manages and withered death, causes the waste of resource.With the influence of greenhouse effects, China's summer is more and more hotter, and temperature is increasingly Height, sunlight are more fierce.The plantation shell of existing plantation flowers, no sunshade function, in summer, plant is straight by fierce sunlight It if penetrating, usually can all be burnt, if in the more long of fierce sunlight decentralization, can also directly be dried up.

Such as application number：201610784096.4 the utility model discloses a kind of adjustable sun-shading device of flowerpot, packet Support tube is included, the support tube lower end has been wholely set pedestal, and threaded hole, the support tube upper end are provided in the support tube It is threaded with positioning screw, the positioning screw upper end is welded with metal snake leather hose, the upper end welding of the metal snake leather hose There are connecting rod, the connecting rod upper end to be detachably provided with sky shade mounting bracket, sunshade is provided on the sky shade mounting bracket It covers, two hanging rings is at least symmetrically arranged on the sky shade mounting bracket, and each hanging ring is integrally set with sky shade mounting bracket It sets.Above-mentioned technical proposal, it is reasonable in design, simple in structure, strong sunlight can be blocked, prevent plant from being burnt, practicability It is good.

Such as application number：201220711879.7 a kind of multiple field flower cultivation greenhouse, is related to agricultural facility technical field, The cultivation greenhouse being made of fiberglass including one, it is characterised in that：The cultivation inside greenhouse is equipped with supporting rack, support frame as described above It is equipped with the internal sunshade layer that can be covered and cultivate greenhouse top, is equipped with insulating layer above the internal sunshade layer, on the insulating layer Side is equipped with protective layer, is equipped with external sunshade layer above the protective layer, and wherein internal sunshade layer and external sunshade layer is using being capable of open-close type Design, can be closed at any time when not needing sunlight, ensure required temperature in greenhouse.The utility model will be trained Foster top of greenhouse is designed to multilayered structure, can effectively ensure the required temperature of warm indoor flower and illumination condition, to flower Grass provides suitable growing environment.

Based on above-mentioned, the utility model people discovery, the flowers solar protection devices designed by above-mentioned two patent actually makes With having the following disadvantages in the process：1, the demand of its different required sunlight intensity of the type of flowers is also just different, on Although sunlight can be sheltered from by stating the flowers solar protection devices designed by two patents, the exposure intensity of sunlight can not be carried out It adjusts, if the exposure intensity for sheltering from sunlight that set solar protection devices is excessive, can cause flowers by less than required Sunlight influences the growth of flowers, if the exposure intensity for sheltering from sunlight that set solar protection devices can not be excessive When, it is certain to the lower flowers of sunlight demand after the long-time sunlight excessive by this, which can be caused Damage, influences the normal growth of the flowers；Further, the sunlight intensity of different periods is also had nothing in common with each other, when in just When period of the day from 11 a.m. to 1 p.m section sunlight is the strongest, its shaded effects that can be played of set single puggaree also can greatly drop It is low, also may flowers be caused with excessive sunlight.

Then, it in view of this, being studied improvement for existing structure and missing, provides for the treasure in Garden Engineering Your flowers exempts from the adjustable shielding device being exposed to the sun for a long time, to achieve the purpose that with more more practical value.

Utility model content

In order to solve the above-mentioned technical problem, the utility model is provided exempts from for a long time cruelly for the precious flowers in Garden Engineering The adjustable shielding device of solarization is deposited in actual use with solving the flowers solar protection devices designed by above-mentioned two patent In insufficient problem.
