A spartina alterniflora treatment shading device based on a photovoltaic pile foundation

Abstract

This utility model discloses a shading device for controlling Spartina alterniflora based on photovoltaic pile foundations, including a column and a U-shaped limiting component. The column has a slot at its top, and a fixing ring is connected to the slot. The lower end of the column is tapered. Threaded holes are formed at both ends of the fixing rings. A steel wire rope is arranged between two sets of fixing rings, and a movable head is rotatably connected to the end of the steel wire rope. Second buckles are evenly fixed to the four sides of the upper surface of the shading cloth. A gap-sealing cloth is placed between adjacent sets of shading cloths. The first, second, and third buckles have identical structures. This shading device for controlling Spartina alterniflora based on photovoltaic pile foundations can effectively block gaps in the shading cloth after it is laid, preventing sunlight from shining through these gaps and improving the shading effect of the device, by evenly arranging the second buckles on the four sides of the upper surface of the shading cloth in conjunction with the use of the gap-sealing cloth.

Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic power plant areas, specifically a shading device for controlling Spartina alterniflora based on photovoltaic pile foundations. Background Technology

[0002] Spartina alterniflora has a strong ability to regenerate, and its spread may block photovoltaic modules and reduce power generation efficiency. Spartina alterniflora is a sun-loving organism, and its reproduction mainly relies on sunlight for photosynthesis. Therefore, shading can be used to inhibit the growth of Spartina alterniflora.

[0003] Existing shading devices mostly use shading cloth fixed on piles to block sunlight. However, gaps exist between the piles and between adjacent sets of shading cloth, allowing sunlight to filter through and affecting the shading effect. Furthermore, the shading cloth can be blown around by strong winds after installation, causing it to curl up. Therefore, we propose a shading device for Spartina alterniflora control based on photovoltaic piles to solve the problems mentioned above. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a shading device for controlling Spartina alterniflora based on photovoltaic pile foundations, including a column 1 and a U-shaped limiting member 9. A slot 2 is formed on the upper part of the column 1, and a fixing ring 3 is connected to the slot 2. The lower end of the column 1 is tapered. Threaded holes 4 are formed at both ends of the fixing rings 3. A steel wire rope 5 is arranged between the two sets of fixing rings 3, and a movable head 6 is rotatably connected to the end of the steel wire rope 5. The steel wire rope 5 forms a threaded disassembly and installation connection with the threaded holes 4 on the surface of the fixing rings 3 through the movable head 6, facilitating the connection between the steel wire rope 5 and the fixing rings 3. The installation between the steel wire ropes 5 includes a shade cloth 7, which comprises a first polyester fiber fabric layer 701, a second polyester fiber fabric layer 702, a cotton and linen fabric layer 703, and a fiberglass protective net 704. The cotton and linen fabric layer 703 and the fiberglass protective net 704 are bonded together with hot melt adhesive between the first polyester fiber fabric layer 701 and the second polyester fiber fabric layer 702, and the cotton and linen fabric layer 703 is located below the fiberglass protective net 704, so as to improve the firmness of the shade cloth 7 through the cotton and linen fabric layer 703 and the fiberglass protective net 704.

[0023] Please see Figure 1-6The shade cloth 7 has first buckles 8 evenly fixed at both ends. The shade cloth 7 is connected to the steel wire rope 5 by the first buckles 8. A U-shaped limiting member 9 is provided through the surface of the steel wire rope 5 at the corresponding position of the first buckle 8. The end of the U-shaped limiting member 9 is fixedly connected to the steel wire rope 5 by a fastening nut 10. The first buckles 8 on the surface of the shade cloth 7 are limited by the U-shaped limiting member 9 and the fastening nut 10. The upper surface of the shade cloth 7 has two second buckles 11 evenly fixed on all four sides. The second buckle 11 is composed of a first clamping plate 1101, a tough steel strip 1102, a second clamping plate 1103, and a sewing groove 1104. A tough steel strip 1102 is welded between the first clamping plate 1101 and the second clamping plate 1103. The tough steel strip 1102 is arc-shaped. A sewing groove 1104 is provided at the end of 1101. The length of the first card 1101 is greater than the length of the second card 1103. The use of the tough steel strip 1102 between the first card 1101 and the second card 1103 facilitates the movement of the second card 1103, so as to facilitate the use of the buckle. A seam-covering cloth 12 is provided between two adjacent sets of shade cloths 7. The two ends of the seam-covering cloth 12 are fixed with third buckles 13. The first buckle 8, the second buckle 11 and the third buckle 13 have the same structure. The third buckles 13 at both ends of the seam-covering cloth 12 and the second buckles 11 on the surface of the shade cloth 7 form a buckle connection. The material of the seam-covering cloth 12 is the same as the material of the shade cloth 7, so as to facilitate the use of the seam-covering cloth 12 to cover the gap between the shade cloths 7 and improve the shading effect of the device.

[0024] Working principle: First, the column 1 is inserted into the photovoltaic pile base, and the movable head 6 at the end of the steel wire rope 5 is connected to the threaded hole 4 on the surface of the fixed ring 3. Then, the shade cloth 7 is fastened to the steel wire rope 5 through the first buckle 8. The surface of the steel wire rope 5 is provided with U-shaped limiting parts 9 that correspond one-to-one with the first buckle 8. With the use of the fastening nut 10, the first buckle 8 at the end of the shade cloth 7 can be easily limited, so as to prevent the shade cloth 7 from rolling up when the wind blows.

[0025] When encountering two adjacent sets of shade cloth 7, the gap between the two sets of shade cloth 7 can be blocked by the gap cloth 12 to prevent sunlight from entering the ground through the gap. The third buckle 13 at both ends of the gap cloth 12 can be fastened to the second buckle 11 on the upper side of the shade cloth 7, which facilitates the installation of the gap cloth 12.

[0026] A cotton-linen fabric layer 703 and a fiberglass protective net 704 are provided between the first polyester fiber fabric layer 701 and the second polyester fiber fabric layer 702 on the shading cloth 7, which can improve the firmness of the shading cloth 7. This is the working principle of the shading device for controlling Spartina alterniflora based on photovoltaic pile foundation.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
