Description

Section bar for installing sunlight shed covering film

Technical Field

The invention relates to the technical field of water tank profile structures for draining sunlight sheds, in particular to a profile for installing a sunlight shed covering film.

Background

In the greenhouse, the water tank is used for guiding and draining rainwater flowing down along the covering film, the cross section of the existing water tank profile is shown in fig. 1, in order to fix the edges of the covering film on the top of the sunlight greenhouse on the water tank in the use process, one covering film mounting clamping piece is required to be welded on the tops of two sides of the water tank, and the covering film can be fixed on the water tank through the covering film mounting clamping piece, and the structure schematic diagram of the covering film mounting clamping piece is shown in fig. 2. The welded structure has the following defects: (1) During production, two different cold bending forming devices are needed, the water tank and the cover film mounting clamping piece are respectively rolled, the two devices are welded after the rolling forming, the investment is large, the occupied area of a factory building is large, the labor is large, and the cost is high; (2) When the coating film is installed, the coating film installation clamping piece is required to be welded on the water tank, and the welding point is extremely easy to rust due to the fact that the galvanized layer between the water tank and the coating film installation clamping piece is damaged by welding, so that the service lives of the water tank and the coating film installation clamping piece are shortened; in addition, the welding of the water tank and the cover film mounting clamping piece belongs to spot welding, and the welding part is easy to fall off or tear due to the influence of factors such as heat expansion and cold contraction or stress bending of the water tank in the use process, so that the use is influenced; (3) The gap between the water tank and the cover film mounting clamp can cause leakage, which brings inconvenience to users.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide the sunlight shed covering film installation profile which has the advantages of compact structure, long service life, integrated forming of the clamping groove and the water tank, improvement of the covering film installation efficiency and avoidance of film scratching.

The aim of the invention is achieved by the following technical scheme: the utility model provides a sunshine canopy tectorial membrane installation is with section bar, it includes basin and draw-in groove, the basin include the bottom plate and with two lateral walls of bottom plate integrated into one piece, the draw-in groove has been buckled at the top of two lateral walls, and the draw-in groove sets up along lateral wall length direction, the bottom surface and the lateral wall parallel arrangement of draw-in groove are provided with bar form jump ring in the draw-in groove, the top in the draw-in groove outside is provided with the circular arc portion of outwards turning up.

An upper bulge and a lower bulge are formed on the outer wall of the clamping groove.

The upper bulge is arc-shaped.

The water tank comprises a pin shaft and two side walls, wherein the bottoms of the two side walls are hinged through the pin shaft.

The inner sides of the two side walls are provided with mud-blocking filter screens which are perpendicular to the side walls.

The invention has the following advantages: (1) The side wall of the water tank and the clamping groove are rolled simultaneously, only one cold roll forming machine is needed, the investment is less, the occupied area of a factory building is small, the labor is reduced, and the cost is reduced; (2) When the water tank is installed, the water tank and the clamping groove are not used, and the galvanized layer of the water tank and the clamping groove cannot be damaged, so that the water tank and the clamping groove are not easy to rust, and the service life of the water tank and the clamping groove is prolonged. Moreover, no gap exists between the water tank and the clamping groove, so that leakage is avoided; (3) The profile is not torn due to the influence of factors such as expansion with heat and contraction with cold or stress bending of the water tank in the use process; (4) The section bar enhances the bending strength of the side wall of the water tank main body; (5) The outside of the clamping groove is provided with an upward bulge, and the rigidity of the supporting part is enhanced due to the bulge. (6) The drainage capacity can be adjusted according to the rainfall capacity, so that the cover film is prevented from being damaged by rain water pressure. (7) The mud blocking filter screen can intercept leaves or mud which are washed out from the cover film, and avoid the blockage of the water tank.

Detailed Description

The invention is further described below with reference to the accompanying drawings, the scope of the invention not being limited to the following:

embodiment one: as shown in fig. 3-6, a sunshine canopy tectorial membrane installation is with section bar, it includes basin and draw-in groove 1, the basin include bottom plate 2 and with bottom plate 2 integrated into one piece's two lateral walls 3, the material of this section bar is the steel sheet, the top of two lateral walls 3 is buckled and is had draw-in groove 1, draw-in groove 1 sets up along lateral wall 3 length direction, the bottom surface and the lateral wall 3 parallel arrangement of draw-in groove 1 are provided with bar-shaped jump ring 4 in the draw-in groove 1, the top in the draw-in groove 1 outside is provided with outwards turned-over circular arc portion 5, circular arc portion 5 can avoid the sharp edge of steel sheet to scratch the tectorial membrane.

The outer wall of the clamping groove 1 is provided with an upper bulge 6 and a lower bulge, the upper bulge 6 is arc-shaped, the upper bulge 6 is used for being welded with a shed rod for supporting a sunlight shed, and the upper bulge 6 enhances the rigidity of a supporting part.

The working process of the invention is as follows: when the covering film is installed between two sections, the left edge of the covering film 10 is turned over by the arc part 5 positioned on the left section, then the left edge sequentially passes through the clamping groove 4 and the top of the side wall 3 downwards, then the strip-shaped clamping spring 4 is pressed into the clamping groove 4, the left edge of the covering film 10 is fixed by the clamping spring 4 under the action of the spring restoring force, and finally the right edge of the covering film 10 is fixed in the clamping groove 4 positioned on the right section by adopting the same method, so that the covering film is quickly installed and fixed by using the clamping spring 4. In rainy days, rainwater falls into the water tank along the cover film 10, and is discharged from the water tank, thereby reducing the gravity of the cover film.

Embodiment two: as shown in fig. 7, the present embodiment differs from the first embodiment in that: the water tank comprises a pin shaft 7 and two side walls 3, wherein the bottoms of the two side walls 3 are hinged through the pin shaft 7. The inner sides of the two side walls 3 are provided with mud-blocking filter screens 9, and the mud-blocking filter screens 9 are perpendicular to the side walls 3. Because the cavity area of current basin is fixed, consequently the drainage ability is unchangeable, nevertheless when meetting rainfall unusual big, rainwater overflows from the basin easily, only needs to outwards overturn two lateral walls 3 in this embodiment around round pin axle 7 this moment, changes the cavity area, further increases the drainage ability, avoids the bad tectorial membrane of rainwater pressure. The mud blocking filter screen 9 can intercept leaves or silt washed down from the cover film, effectively avoid the water tank to be blocked, and ensure the smooth proceeding of drainage.

The foregoing is merely a preferred embodiment of the invention, and it is to be understood that the invention is not limited to the form disclosed herein but is not to be construed as excluding other embodiments, but is capable of numerous other combinations, modifications and environments and is capable of modifications within the scope of the inventive concept, either as taught or as a matter of routine skill or knowledge in the relevant art. And that modifications and variations which do not depart from the spirit and scope of the invention are intended to be within the scope of the appended claims.
