Description
Technical field
It the utility model is related to greenhouse equipment technical field；More particularly to a kind of heater of greenhouse ventilating system.
Background technology
Greenhouse is a kind of accumulation and conversion solar energy, and the luminous energy of the sun is partially converted into heat energy, to meet that crop gives birth to
The long facility needed.Also need to carry out appropriate ventilation according to the temperature change in canopy during the use of greenhouse, adjust
The temperature in canopy is saved, makes up to the optimal needs of plant growth different times, can neither be too high, can not be too low.It is if big
Temperature in canopy is too low, and suppression can be produced to the plant growth in canopy, retarding of growing development, vinyl house is promoted early ripening of the crops
The effect of high yield is had a greatly reduced quality；The low crop that will make in canopy by freezing disaster, causes plant growth to be stagnated, largely to temperature again
The underproduction；Lower temperature can then directly contribute plant death.Harm of the high temperature to crop is not sneezed at equally, and temperature exceedes crop
Temperature limit required for growth, plant growth can be equally suppressed；Higher temperature can also make crop leaf burn, extremely
High temperature also result in plant death.The temperature adjustment on greenhouse daytime relies primarily on ventilating opening to carry out at present, but common big
Canopy ventilation condition is poor, can only be typically aerated by the opening at greenhouse both ends, and air circulation is bad, causes greenhouse implants to be given birth to
Length is obstructed.
The U of China patent CN 205546738 disclose a kind of device for slowing down green house of vegetables temperature change, including outside greenhouse
Shell and base, the base are located at the intracavity bottom of greenhouse shell, it is characterised in that and the greenhouse shell is provided with ventilating opening,
The ventilating opening is provided with installing rack of fan, and the first fan is provided with the installing rack of fan, ventilation is provided with the ventilating opening
Groove, the bottom of the ventilation groove are provided with the second fan, and the base is provided with bobbin winoler placed cavity, and the bobbin winoler is placed
Intracavitary is provided with bobbin winoler, and the both sides of the base are provided with accommodating groove, and the accommodating groove inwall is provided with chute, the base storage
The second connecting plate is provided with groove, jack rod sleeve is interspersed with second connecting plate, slide bar, the cunning is socketed with the jack rod sleeve
The both ends of bar are located in the groove position of chute, and the side of second connecting plate away from accommodating groove is connected with expansion plate, described flexible
Plate is provided with installing port, is provided with some heating wire in the installing port, side of the expansion plate away from the second connecting plate is provided with
First connecting plate, steel wire rope is connected with first connecting plate, the steel wire rope is connected to the bottom of accommodating groove, the bottom
The side of seat is provided with some first lockholes.
The above-mentioned device for slowing down green house of vegetables temperature change, certain adjustment effect can be played to the temperature in greenhouse,
But still have following defect：1st, canopy temperature is needed during rise, it is necessary to be heated to heating wire, but heating wire is only
It is only capable of heating its own peripheral part space, heat will not distally spread, if greenhouse needs overall heating, need to set
Multiple devices are put, the waste of device is will also result in while taking space in greenhouse, can also make it that heat is uneven in greenhouse, to making
Thing growth impacts.2nd, when greenhouse needs heating, expansion plate expansion drives heating wire synchronous expansion, and space-consuming is big, makes
Obtain script in greenhouse and hard up space becomes narrower.3rd, whole device is complicated, installation and inconvenient maintenance.
In order to solve the above problems, applicant considers to design a kind of greenhouse ventilating system, and its feature is, including is arranged on
The passage of a ventilation on greenhouse, it is provided with the passage for the air-intake device of greenhouse inside air intake, in addition to one
The individual electric calorifie installation being arranged on passage, the electric calorifie installation, which has, is used for electrically heated electric heating element, it is characterised in that described logical
The electric calorifie installation is corresponded on road and is provided with opening, the electric calorifie installation also includes one set on the passage of the opening side
Individual telescoping mechanism, the telescoping mechanism and the electric heating element are connected and can driven described in the electric heating element from the opening disengaging
Passage.
So, when canopy temperature is higher than temperature needed for plant growth, air-intake device can be made with being divulged information into greenhouse
Obtaining canopy temperature reduces.When canopy temperature is less than temperature needed for plant growth, telescoping mechanism, which acts, causes electric heating element to arrive
Up to channel interior, the wind of air-intake device blowout heats after-blow to greenhouse inside through electric heating element, while is also possible that heat is carried out
Diffusion so that temperature of shed is more uniform.
But due to being provided with opening on passage, the wind that air-intake device is blown out can be caused to be heated without electric heating element, just from opening
Outflow, heating required time inside greenhouse can be extended, cause the operating efficiency of the device to reduce.So how using simple knot
Structure improves the efficiency that the device heats up to greenhouse inside, and the time required to reducing temperature rise, turning into has considered solve the problems, such as.
