[0004] And the prior art, a kind of anti-seepage geomembrane deployment device with announcement number CN219098248U.

[0005] The above-mentioned technical solutions still have the following shortcomings. Since the geomembrane needs to be unfolded with tension, the tension disappears after the geomembrane is broken. At this time, if the broken part of the geomembrane is not limited, it is easy to be separated from the geomembrane body under the action of elastic potential energy, and subsequent processing is inconvenient. Therefore, we propose a geomembrane unfolding device to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a geomembrane unfolding device to solve the problems raised in the above background technology.

[0007] To achieve the above object, the utility model provides the following technical solutions: It includes a chassis. Above the rear end of the chassis, there is a first pillar.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides a technical solution for a geomembrane unfolding device:

[0023] Embodiment:

[0024] As Figure 1 , Figure 2 and Figure 3As shown in the figure, it includes a chassis 1. Above the rear end of the chassis 1, a first support column 4 is provided. At the top of the first support column 4, a U-shaped support block 5 is connected. A roller 6 is movably arranged in the inner cavity of the U-shaped support block 5. A second support column 15 is connected to the side wall of the first support column 4. On one side of the second support column 15, a first motor 16 is provided. One end of the first motor 16 is connected to a feeding roller 18. One end of the feeding roller 18 is connected to a rotating rod 17. A gear 19 is provided at one end of the rotating rod 17. Above the front end of the chassis 1, a third support column 21 is provided. On one side of the third support column 21, a second motor 22 is provided. One end of the second motor 22 is connected to a lead screw 23. A slider 24 is sleeved outside the lead screw 23. The bottom of the slider 24 is connected to a sliding knife 25. A support rod 26 is arranged between the two third support columns 21. A cutting groove 27 is formed through the top of the support rod 26.

[0025] Among them, the two rotating rods 17 are linked through the gear 19, and the lower end of the sliding knife 25 is located in the inner cavity of the cutting groove 27.

[0026] Among them, a rubber sleeve 9 is sleeved outside the roller 6, and the rubber sleeve 9 is located between the U-shaped support block 5 and the roller 6.

[0027] In this embodiment, when in use, the main body of the geomembrane is sleeved on the outer ring of the roller 6. Then the roller 6 is placed on the U-shaped support block 5. At this time, the end of the geomembrane is pulled out, and then passed through between the two feeding rollers 18 and through between the support rod 26 and the lead screw 23. At this time, the first motor 16 is started, and the feeding rollers 18 apply a pulling force to the geomembrane. The roller 6 rotates under the influence of the pulling force in the U-shaped support block 5, thereby peeling the geomembrane to achieve the purpose of unfolding the geomembrane. When it is necessary to cut the geomembrane, the second motor 22 drives the lead screw 23 to rotate. Then the lead screw 23 drives the slider 24 to move through the thread. At this time, the sliding knife 25 connected to its bottom can cut the geomembrane. Since the geomembrane is clamped between the two feeding rollers 18, when the geomembrane is cut off, the cut-off part will not be thrown away, and the use safety is relatively high. In terms of the main body of the geomembrane, due to the setting of the rubber sleeve 9, the damping of the rotation of the roller 6 is increased. When the first motor 16 stops working, the amplitude of the rotation of the roller 6 affected by inertia can be reduced, thereby avoiding the situation that the geomembrane unfolds after the equipment stops. The overall practicality is improved. At the same time, since the roller 6 is easy to remove, it is convenient to load and unload the geomembrane, and the overall use convenience is relatively high.

[0028] Among them, as Figure 3 and Figure 4 shown, a fixing block 10 is arranged in the inner cavity of the roller 6. A screw rod 11 is arranged between the two fixing blocks 10. A connecting frame 12 is sleeved outside the screw rod 11. The end of the connecting frame 12 is connected to a U-shaped support rod 14. A nut 13 is threadedly connected to the outer ring of the screw rod 11.

[0029] In this embodiment, after the geomembrane main body is sleeved on the outer ring of the roller 6, the extending length of the U-shaped support rod 14 is adjusted through the connecting frame 12 at this time, and then it can be locked by the nut 13, so as to support the geomembrane main body from the inside, avoiding the self-rotation of the geomembrane main body, so as to ensure that the rubber sleeve 9 can effectively play a limiting role.

[0030] Among them, as Figure 3 shown, a fixing ring 7 is fixedly arranged on the outer ring of the roller 6, and a rotating ring 8 is arranged on one side of the fixing ring 7.

[0031] In this embodiment, the fixing ring 7 is used to limit the rotating ring 8. After the geomembrane main body is sleeved on the outer ring of the roller 6, at this time the geomembrane main body is located within the two fixing rings 7. At this time, the rotating ring 8 is sleeved on the outer ring of the roller 6. Then when the roller 6 is erected in the U-shaped support block 5, the rotating ring 8 is located between the geomembrane main body and the U-shaped support block 5 to limit the geomembrane main body, and at the same time, it can avoid the side of the geomembrane main body from coming into contact with the U-shaped support block 5, resulting in damage during the subsequent unfolding process, further improving the overall practicability.

[0032] Among them, as Figure 1 shown, both ends of the chassis 1 are connected with support feet 2, through holes 3 are opened through the tops of the support feet 2, and a reinforcing plate 20 is connected to the side wall of the second pillar 15, and the reinforcing plate 20 is triangular.

[0033] In this embodiment, the whole device can be connected to an external moving or fixed platform through the through holes 3; the reinforcing plate 20 is used to improve the connection strength between the second pillar 15 and the first pillar 4, avoid the structure from bending, and thus improve the durability of the device.

[0034] In the description of the present invention, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
