Example 1:

the embodiment specifically explains the case of collecting the condensed water attached to the inner surface of the film 16 when the greenhouse ceiling 13 is in different states: with reference to the structures shown in fig. 1-6 of the specification, the present embodiment provides a membrane fixing and drainage system for a top full-open window, which includes a gutter, a ceiling 13 hinged to the gutter for realizing top opening or closing of a greenhouse, and a membrane fixer 15 close to the gutter and fixedly mounted on the upper surface of the ceiling 13 for fixing a membrane 16 covering the ceiling 13, wherein the membrane fixer 15 is provided with a second drip groove 26 for collecting condensed water attached to the inner wall of the membrane 16, and the second drip groove 26 is communicated with the gutter through a drainage hose 14.

For obtaining this application preferred technological effect, the current structure setting of using the roof ridge to install as the center of innovation, the gutter specifically adopts following structure to form, specifically, the gutter includes integrated into one piece and upswept body 1, links firmly with two inside walls of body 1 and is used for forming 1 top open-ended apron 4 of sealed body, the symmetry be provided with on the apron 4 two be used for with ceiling 13 articulated support 6, apron 4 forms both ends open-ended first gutter 11 with body 1.

In consideration of more convenient and effective collection of condensed water on the inner wall of the membrane 16, the two side edges of the body 1 extend upwards to form extension parts 3, and the extension parts 3 are higher than the cover plate 4; the inner side wall of the extension 3, the upper surface of the cover plate 4, and the outer side wall of the bracket 6 form a first drip groove 5 for collecting and discharging condensed water from the drain hose 14. Alternatively, the drainage hose 14 may also penetrate through the cover plate 4 or the body 1 to communicate with the first drainage channel 11, so as to directly discharge the condensed water into the first drainage channel 11, and discharge the condensed water to the outside of the shed through two ends of the first drainage channel 11, thereby better avoiding the possibility of the condensed water overflowing into the shed, and being safer and more reliable.

Based on the consideration of function integration, the whole greenhouse structure is simplified, the greenhouse structure is compatible with different requirements, and the installation is convenient, at least one T-shaped rib 9 is integrally formed between two brackets 6 on the cover plate 4, and a second installation groove 10 with a convergent top opening is formed between two adjacent ribs 9 and/or between the rib 9 and the bracket 6; two side walls of the body 1 are inwards concave to form a first mounting groove 2 with a convergent opening for mounting a fixing bolt.

The working principle is as follows:

a first part: the structure and the installation are illustrated, the gutter is fixedly installed on the framework of the greenhouse and used for supporting the ceiling 13 and draining water, the ceiling 13 is hinged on the support 6 and is driven by the motor to rotate relative to the support 6, as shown by an arc arrow in fig. 1, so that the top of the greenhouse is opened or closed. The upper surface of the ceiling 13 close to the bracket 6 is fixedly provided with a film fixer 15, and the film 16 is fixed and pressed by the film fixer 15, so that the film 16 is fixed on the ceiling 13. The film fixing device 15 has a second drip groove 26, and the second drip groove 26 penetrates the cover plate 4 through the drain hose 14 into the first drain groove 11.

A second part: the state and the principle are explained, when the ceiling 13 is in a closed state, the inclined angle of the ceiling 13 relative to the horizontal plane is small, the condensed water can be naturally attached to the film 16, when the condensed water is continuously gathered and the adhesive force of the water drops is not enough to overcome the downward sliding component force of the water drops under the action of gravity, the condensed water drops can slide down along the inner wall of the film 16 until reaching the film fixer 15, and because the film fixer 15 and the film 16 realize closed pressing, the condensed water automatically falls into the second dripping groove 26.

Similarly, when the ceiling 13 is opened, the angle of the ceiling 13 with respect to the horizontal plane is increased, the gravity sliding component of the condensed water is increased gradually, and the condensed water will slide into the second drip groove 26 along the inner wall of the film 16 at an accelerated speed. When the condensed water in the second drip groove 26 accumulates, it will naturally enter the first drain groove 11 through the drain hose 14, and finally will be discharged to the outside of the shed through the first drain groove 11 through the openings at both ends.

The present embodiment also provides another condensate water drainage scheme, i.e. the condensate water flows into the first drip chamber 5 directly through the drain hose 14, and the condensate water is drained out of the shed along the two ends of the first drip chamber 5. The scheme is suitable for greenhouses with relatively small condensed water amount, and the technical scheme of the first drainage groove 11 is preferably adopted for greenhouses with large space or greenhouses with high humidity.

Example 2:

this embodiment is focused through carrying out the tensioning so that better collection comdenstion water to the film 16 of ceiling 13, avoids causing the comdenstion water that the wriggling of film 16 produced directly to drip the big-arch shelter owing to the film 16 rate of tension inadequately, causes the comdenstion water to cause the adverse effect to the melon and fruit vegetables of planting in the big-arch shelter. In order to achieve the technical effect, with reference to the structure shown in fig. 3-6 of the specification, the film fixer 15 includes a film fixing section 17 for being fixedly mounted on the ceiling 13, the film fixing section 17 includes a second groove 19 for pressing a film and the second drip groove 26, and a prepressing device 22 for pressing and fixing the film 16 into the second groove 19.

For better fixing and tensioning the film, avoiding the creeping of the film and improving the wind resistance, the film fixing section 17 further comprises a first groove 18 arranged between the second dripping groove 26 and the second groove 19, and the pre-pressing device 22 is hinged with a tensioning device 23 which can press or semi-press the film 16 into the first groove 18 and is used for tensioning the film 16.

In a preferred embodiment of the present invention, a film protecting portion 21 having a smooth structure is disposed between the second droplet groove 26 and the first groove 18; a partition 20 is arranged between the first groove 18 and the second groove 19, and a smooth structure or an expanded structure for supporting the film 16 is arranged at the top end of the partition 20. The tension device 23 has a pressing portion 24 at one end for pressing the film 16, and the pressing portion 24 has an arc-shaped structure formed by bending in any direction or an expanded structure with a smooth surface.

The working principle is as follows:

the specific operation and principle in performing the securing and tensioning of the membrane 16 is illustrated in fig. 3-5; the pre-press means 22 is first pressed into the second groove 19 in the direction indicated by the arrow a in fig. 3, so that a preliminary fixing of the film 16 is achieved. However, in the state, no matter how the film 16 is tensioned, a margin exists, the creeping condition exists, the wind resistance performance is poor, and in the creeping process, condensed water directly falls into the shed to cause damage; at this time, the film 16 is pressed or semi-pressed into the first groove 18 through the pressing part 24 by the tensioning device 23 until the film 16 is tensioned, so that the problem of dripping of condensed water generated by creeping of the film 16 or damage of the film 16 is avoided, and the pressing direction is shown as an arrow B in FIG. 4, so that the film 16 is moved and tensioned in the direction of an arrow C in FIG. 5. As shown in fig. 5, this embodiment shows a method that can adjust the pressing force and thus the tension of the film 16, and when the film 16 is pressed, the integrated lamination can be realized by using tapping screws for installing the film fixing device 15. As shown in two ways of fig. 5 and 6, in fig. 6, the self-tapping screws are used to directly fix the tension device 23, the pre-pressing device 22 and the membrane fixing section bar 17 together, the tension degree of the membrane 16 is realized by changing the distance between the tension device 23 and the pre-pressing device 22, the closer the distance between the tension device 23 and the pre-pressing device 22 is, the greater the tension force is, and the smaller the tension force is. Meanwhile, the tensioning can also be performed in the manner shown in fig. 5, which requires a through hole to be opened on the tensioning device 23, and an elastic unit, such as a spring, is sleeved on the tail of the fixing screw rod or the screw, so that the elastic unit is always in a compressed state and is placed between the tail of the screw and the tensioning device 23. The beneficial effect of adopting this kind of mode is that through the elastic action of elasticity unit self, can compensate film 16 under different temperature circumstances, because self elasticity or plastic deformation lead to the different problem of degree of tension of film 16 itself. For example, the internal tension of the fixed tensioning film 16 is different in the low temperature state in winter and the high temperature state in summer, and the elastic unit is arranged, so that the tension of the film 16 can be effectively compensated, and the film can be always relatively stable.

Example 3:

the drainage and the emission of rainwater outside the canopy are mainly explained to this embodiment, and this embodiment can satisfy the drainage of big precipitation or the torrential rainfall and discharge, can not make gutter ponding can not in time discharge and lead to the rainwater to enter into the problem of influencing the crop in the canopy through the gap between gutter and ceiling 13 because of the torrential rainfall.

In order to realize the sealing effect inside and outside the greenhouse, at least one film fixing groove 7 for hermetically pressing the free end of the film 16 covered on the ceiling 13 is symmetrically arranged on the opposite sides of the two supports 6. As shown in fig. 1 and 2, the film fixing groove 7 is used for hermetically pressing the free end of the film 16 covering the ceiling 13, which is close to one side of the gutter, so that an airtight whole is formed between the ceiling 13 and the gutter, complete airtight isolation inside and outside the greenhouse is realized, the air tightness can be improved on one hand, the drainage of the gutter to rainwater can be met on the other hand, the rainwater drainage device can adapt to and deal with the drainage of the sudden large precipitation amount, the rainwater is prevented from entering the greenhouse through the joint between the gutter and the ceiling 13 due to the excessive depth of the rainwater, and the greenhouse environment in the greenhouse is prevented from being influenced by external weather.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
