Detailed Description

The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and those skilled in the art will be able to make and use the invention as long as various changes are within the spirit and scope of the present invention as defined and defined by the appended claims, and are intended to be protected by the present invention.

As shown in fig. 1 to 3, the rain sheltering greenhouse intelligent ventilation device comprises a ventilation opening 1 arranged on greenhouse cloth and a heat dissipation device 3 arranged on an upright post 2 in the coverage area of the ventilation opening 1, wherein the upright post 2 is a hollow pipe; when the heat dissipation device 3 of the present scheme does not dissipate heat, the sleeve 33 does not completely overlap the column 2, the upper end of the sleeve contacts the greenhouse cloth and completely covers the vent 1, that is, when the heat dissipation device 3 does not dissipate heat, the heat dissipation device 3 closely contacts the greenhouse cloth to prevent rainwater from entering.

As shown in fig. 1 and 2, the heat sink 3 includes a controller, an electric push rod 31 and a connection block 32 fixedly installed in the inner cavity of the upright 2, specifically, the connection block 32 is welded in the inner cavity of the upright 2 and is used for supporting the electric push rod 31 and components installed on the electric push rod 31 and preventing the heat sink 3 from sliding downwards along the upright 2, and the controller is a single chip microcomputer using an STC89C52RC chip.

The push rod of the electric push rod 31 is fixed in the sleeve 33, the end far away from the push rod is fixed on the connecting block 32, and after the electric push rod 31 and the sleeve 33 are fixed at , the gravity center direction and the motion direction of components mounted on the sleeve 33 are on straight lines when the electric push rod 31 extends and retracts to ensure the motion stability of the heat dissipation device 3.

The inner diameter of the sleeve 33 is larger than the outer diameter of the upright post 2 or the outer diameter of the sleeve 33 is smaller than the inner diameter of the upright post 2, and when the electric push rod 31 moves to the maximum stroke, the lower end of the sleeve 33 is positioned in the upright post 2 or the upper end of the upright post 2 is positioned in the sleeve 33.

The above limitation on the size of the sleeve 33 is actually to explain two installation manners of the sleeve 33, that is, types are that the sleeve 33 is located in the inner cavity of the upright post 2, and types are that the upright post 2 is sleeved in the inner cavity of the sleeve 33, and regardless of which types of the two manners the sleeve 33 is installed, the electric push rod 31 is always located in the upright post 2 during installation.

The upper end of the sleeve 33 is fixedly provided with a support frame 34, the support frame 34 is connected with a sealing shed cloth 35 with the size larger than that of the vent 1, and the sealing shed cloth 35 is made of the same material as the greenhouse shed cloth.

When the cross-section of big-arch shelter top installation big-arch shelter canopy cloth part structure is triangle-shaped, when the stand 2 of every big-arch shelter both sides was less than the height of middle row stand 2 promptly, the preferred vent 1 of this scheme is located the top of big-arch shelter canopy cloth, and its appearance is umbelliform, and support frame 34 is the umbelliform skeleton with 1 appearance assorted of vent, and support frame 34 includes the bracing piece 341 parallel with big-arch shelter canopy cloth top.

After the support frame 34 adopts the above structure, its cross-section is triangle-shaped, can improve the stability of support frame 34, when electric putter 31 is located the maximum stroke and dispels the heat, has sections overlapping sections between sleeve 33 and stand 2, and heat abstractor 3 is when receiving the wind effect like this, because the limiting displacement of stand 2 can carry out spacingly to sleeve 33 to prevent that sleeve 33 from breaking under great wind-force effect.

The electric push rod 31 is connected with the controller, and the controller and the electric push rod 31 are both connected with the power supply module; the controller of the heat dissipation device 3 is electrically connected with the temperature sensor in the heat dissipation area covered by the heat dissipation device during heat dissipation, and the heat dissipation device 3 can be automatically opened or closed according to the temperature in the greenhouse due to the introduction of the controller, so that the automatic management of greenhouse ventilation is ensured.

Wherein, the controller sets up in stand 2, sets up like this and can hide the controller in stand 2 to improve the theftproof nature of controller.

When the solar cell panel 36 is located in the area inside the greenhouse, independent upright posts 2 need to be installed, and the upright posts 2 extend out of the greenhouse cloth, so that the solar cell panel 36 can be ensured to be located outside the greenhouse and fully receive illumination.

The preferred solar cell panel 36 of this scheme is installed on the stand 2 at big-arch shelter edge, choose for use like this highly be greater than the stand 2 of big-arch shelter edge height can, need not set up the hole that supplies stand 2 to wear out separately on the big-arch shelter, make things convenient for the change of follow-up big-arch shelter canopy cloth.

During implementation, the rain shelter intelligent ventilation device preferably comprises a raindrop sensor 37 mounted on the outer surface of the sealed shed cloth 35, the raindrop sensor 37 is electrically connected with the controller, and the raindrop sensor 37 adopts an SSM-002 type raindrop sensor.

As shown in fig. 4, four strip-shaped grooves 331 for accommodating the supporting ropes for supporting the greenhouse cloth are formed in the side wall of the sleeve 33, an opening of the strip-shaped groove 331 is located at the lower end of the sleeve 33, and the length of the strip-shaped groove 331 is smaller than that of the sleeve 33.

The setting of bar groove 331 can be blocked crossing support rope in the bar groove 331, and the sleeve is when the motion like this, and support rope does not contact with the sleeve to avoid support rope to block telescopic up-and-down motion.

In conclusion, through the ventilation device arranged on the greenhouse, the self-adaptive adjustment can be realized, and the temperature in the greenhouse is ensured to be at the better growth temperature of the fruits and vegetables.
