Abstract
Description
Technical Field
[0001] The utility model relates to a fixing device, in particular to a film-covering fixing device. Background Art
[0002] The invasion of Spartina alterniflora has damaged the ecosystem structure and function of China's coastal wetlands, affecting topography, tidal hydrological processes, rhizosphere microorganisms, plants and animals and their habitats, as well as the cycle of elements such as carbon, nitrogen, and phosphorus. Its biggest positive effect may be wave dissipation and bank protection, and promoting siltation and land reclamation, but its negative effects are mainly threats to biodiversity and habitats. Spartina alterniflora threatens native plants through interspecific competition, forming a "green desert", reducing intertidal biodiversity, changing the intertidal food web, and leading to a decrease in the number of benthic organisms and birds.

[0028] In order to enable those skilled in the art to better understand the technical solution in the present application, the technical solution of the present utility model will be clearly and completely described below in conjunction with the drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present application.
[0029] Embodiment 1:
[0030] like Figure 1-6 As shown, a film fixing device is used to fix the film covering the top of the cut stubble of Spartina alterniflora, including a support column 1, a hook 3 and a hook seat 8. The support column 1 is provided with a base 4. The hook 3 is connected to the support column 1 through a pull rope 2; a plurality of hook seats 8 are installed on the film, and the hook seat 8 is provided with a card slot 83; the support column 1 is inserted into the hook seat 8, the hook 3 is hooked in the card slot 83, and the pull rope 2 is straightened.
[0031] It should be noted that the stubble of Spartina alterniflora is specifically: the Spartina alterniflora straw is harvested on the ground manually or mechanically, leaving a stubble of 10 to 15 cm, and all the stubble of the Spartina alterniflora after mowing is pressed down so that the stubble of the Spartina alterniflora is in an inclined state, or it is mowed along the base of the Spartina alterniflora, leaving a stubble within 5 cm, both of which can reduce the damage of the film by the stubble of Spartina alterniflora.
[0032] The film can be a light-proof film, which can block sunlight from irradiating the Spartina alterniflora, and effectively prevent the Spartina alterniflora from photosynthesis.
[0033] A distribution structure of the hook seats on the film is: a plurality of hook seats are arranged at intervals along the edge of the film, and the number of hook seats in the middle part of the film can be set according to needs.
[0034] Another connection mode of the hook: the hook 3 is connected to the bearing platform 4 by the pull rope 2. During use, the support column runs through the hook seat and moves downward, and the bearing platform moves downward with the support column, and the bearing platform passes through the hook seat and moves to the bottom of the film, and the hook is snapped into the slot of the hook seat, and the driving support column is stopped until the pull rope is straightened. At this time, the bearing platform is fixed on the top of the stubble of Spartina alterniflora by pulling the film with the pull rope and the hook. It can prevent the film from being swept away by the tide or strong wind, and can reduce the contact area between Spartina alterniflora and the air. The film is not transparent and can reduce photosynthesis, effectively inhibit the growth of Spartina alterniflora, and achieve the purpose of controlling Spartina alterniflora.
[0035] It is understandable that the support column can be inserted in an inclined manner toward the direction of the sea breeze according to the direction of the sea breeze. The sea breeze blows the film, the film pulls the hook, and the hook pulls the support column through the pull rope, and the support column is further inserted into the mud of the beach, and the support column is further fixed.
[0036] like Figure 1-4 As shown, a cap 4 is provided on the top of the support column. The cap can provide a support platform for striking the support column. When the support column is difficult to insert into the muddy mud, the cap can be hammered to push the support column downward and insert into the mud.
[0037] In order to facilitate the insertion of the support column into the mud of the tidal flat, a tip 5 is provided on the end of the support column 1 away from the base 4.
[0038] One structure of the tip may be: the tip 5 is an inverted cone structure.
[0039] In some embodiments of the present disclosure, a mud grabbing seat 6 is additionally installed. Figure 3 , 4 As shown in FIG. 6 , a mud grabbing seat 6 is provided at one end of the support column 1 away from the cap 4. When the mud grabbing seat is inserted into the mud on the tidal flat, it can grasp the mud on the tidal flat, which is conducive to stabilizing the support column inserted into the mud on the tidal flat.
[0040] like Figure 3 , 4 As shown, a connection structure between the mud grabbing seat and the hook: the mud grabbing seat is connected to the hook through a pull rope. The mud grabbing seat is inserted into the soil and plays a role in grasping the soil entering it. The pull rope is connected to the mud grabbing seat. Compared with the pull rope connected to the support column and the pedestal, the resistance of the pull rope can be increased, and the pull rope can further stably pull the hook, and the hook pulls the film.
[0041] In some embodiments of the present disclosure, a structure of a mud grabbing seat is provided. Figure 3 , 4As shown in FIG. 6 , the mud gripping seat 6 includes at least two claws 61, and the at least two claws 61 are installed along the circumference of the side of the support column 1. At least two claws are inserted into the mud of the beach at the same time, and at least two claws have a gripping effect on the mud in the space surrounded by them, which can help at least two claws to be firmly placed in the mud.
[0042] The number of claws can be 2, 3 or 4, etc. A plurality of claws are inserted into the mud of the beach together, which can help to stably support the support column.
[0043] like Figure 6 As shown, the upper part of the claw 61 is an arc segment, and the lower part is a vertical segment. The arc segment and the vertical segment can be tangentially connected.
[0044] A tip is provided at the bottom of the vertical section. The width of the claw gradually decreases from the end where the arc section is connected to the support column to the tip of the vertical section. The tip can facilitate the claw to be inserted into the root system of Spartina alterniflora. The plurality of claws play a supporting role on the support column.
[0045] In some embodiments of the present disclosure, a structure of a mud grabbing seat is provided. Figure 5 As shown, the hook seat 8 includes a first circular ring 81 and a second circular ring 82 . The second circular ring 82 is placed inside the first circular ring 81 , and is spaced apart from the first circular ring 81 to form a slot 83 , and is connected to the bottom of the first circular ring 81 .
[0046] The second circular ring 82 is provided with a through hole 821 , and the through hole 821 allows the support column 1 to pass through the second circular ring.
[0047] The circumferential diameter of the support platform 4 is smaller than the diameter of the through hole 821 on the second circular ring 82. The support platform can pass through the through hole on the second circular ring, so that the support platform can be moved to the bottom of the film.
[0048] It is understandable that, in order to facilitate the mud grabbing seat to penetrate the second circular ring, the circumferential diameter of the mud grabbing seat is smaller than the diameter of the through hole 821 on the second circular ring 82 .
[0049] In some embodiments of the present disclosure, a material structure of the support column is provided. The support column is made of a steel pipe. The steel pipe may be a stainless steel pipe or a carbon steel pipe. It is understood that when a carbon steel pipe is used, the carbon steel pipe may be sprayed with an anti-corrosion paint. This can improve the ability of the carbon steel pipe to resist seawater corrosion.
[0050] One structure of the pull rope 2 can be a steel wire rope, which has the characteristics of being stronger than wear resistance.
[0051] According to the above embodiments, the working mode of the utility model is as follows:
[0052] like Figure 4 As shown, a fixed film structure of the utility model is provided. The film is covered on the top of the stubble left after mowing.
[0053] The film is provided with a plurality of hook seats 8, each of which is equipped with a support column 1. The support column 1 drives the mud grabbing seat 6 to penetrate the second ring 82 on the hook seat 8, and as it moves, the hook 3 is snapped into the slot 83, and the mud grabbing seat is driven to be inserted into the mud of the tidal flat, and the mud grabbing seat 6 is continuously pushed until it cannot be moved further, and the force applied to the support column is stopped, at which time, the support column is firmly inserted into the soil, and the pull rope is tightened and straightened, so that the film is fixedly covered on the top of the area where the stubble of Spartina alterniflora is left. The film is firmly covered on the top of the area where the stubble of Spartina alterniflora is left under the action of a plurality of the utility model film-covering fixing devices, and the Spartina alterniflora can be isolated from light, effectively hindering the photosynthesis of Spartina alterniflora, and the film can largely isolate the Spartina alterniflora from contacting with the air, effectively hindering the respiration of the Spartina alterniflora, so that the Spartina alterniflora is suffocated to death, and the purpose of elimination is achieved.
[0054] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
