Description

Technical Field

[0001] This utility model relates to the field of sand barrier bag technology, and in particular to a sand barrier bag that can prevent sand from being washed away. Background Technology

[0002] Sandbags, also known as sandbag barriers, are mainly composed of an outer layer of material and an inner filling of sand.

[0003] The main purpose of sand barriers is to prevent wind erosion and sand fixation, protect soil and vegetation, and promote ecological restoration. Sand barriers come in various types, such as flat-laying, vertical, strip-shaped, and composite types. Flat-laying sand barriers are formed by laying sandbags flat on the sand surface to create a sand-fixing barrier; vertical sand barriers are formed by stacking sandbags to create a barrier of a certain height, thus blocking sand; strip-shaped sand barriers are laid in a strip to guide the direction of wind and sand flow; composite sand barriers combine multiple types of sand barriers to achieve a combined effect of fixing, blocking, and transporting sand. Furthermore, based on whether the sandbags have fins, sand barriers can also be divided into finned and finless types. Finned structures increase the rigidity of the bottom of the sand barrier, improving its wind erosion and sand fixation effect.

[0004] For example, in the prior art, Chinese Patent Publication No. CN204343278U, entitled "A Flexible Sandbag and Sand Barrier for Sand Control," describes a sandbag comprising a tube made of flexible fabric, with at least one end of the tube unsealed. Multiple parallel main straps form a strip-shaped sand barrier, or multiple parallel main straps and multiple secondary straps perpendicular to the main straps form a grid-shaped sand barrier. Each main strap is formed by at least two sand-filled tubes sequentially overlapping or splicing together, and each secondary strap is formed by sand-filled tubes. This invention uses soft sandbags, simplifying construction and eliminating the need for pre-leveling the sand, significantly reducing labor and saving costs. Furthermore, controlling the amount of sand filled allows for the creation of sandbags with varying hardness to meet the needs of different terrains. This sandbag and sand barrier invention is suitable for various sandy areas, especially in areas where materials such as wheat straw, rice straw, reeds, and willow branches are scarce, playing an irreplaceable role.

[0005] However, the above-mentioned patent still has shortcomings. When fixing the unsealed part of the sand barrier bag, it is often necessary for workers to tighten the two ends of the rope and tie them together. Since tightening the rope and tying it together is cumbersome, it further reduces the installation efficiency of the unsealed part of the sand barrier bag.

[0006] Therefore, in order to address this problem, this utility model provides a sand barrier bag that can prevent sand from being washed away. Utility Model Content

[0007] The purpose of this invention is to solve the problems in the prior art by proposing a sand barrier bag that can prevent sand from being washed away.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A sand barrier bag designed to prevent sand from being washed away includes a sand barrier bag body, at least one end of the sand barrier bag body being unsealed. A limiting sleeve is provided at the unsealed end of the sand barrier bag body. A tightening rope is provided inside the limiting sleeve. A fixing mechanism is provided on the surface of the tightening rope. The fixing mechanism is used to lock the surface of the tightening rope. The fixing mechanism includes a plastic seat fitted on the surface of the tightening rope. A channel one is opened on the surface of the plastic seat. A pressing block is slidably connected inside the plastic seat. A channel two is opened on the surface of the pressing block. The tightening rope passes through the interior of the channel one and the channel two.

[0010] Preferably, the bottom of the sand barrier bag body is provided with protrusions, and the number of protrusions is multiple sets arranged at equal intervals.

[0011] Preferably, the surface of the sand barrier bag body is provided with grooves, and the number of grooves is multiple sets that are equally spaced.

[0012] Preferably, the sand barrier bag body is provided with connecting rings on both sides, and the number of connecting rings is multiple.

[0013] Preferably, the sand barrier bag body is made of a biodegradable flexible fabric, and the flexible fabric of the sand barrier bag body is a non-woven fabric.

[0014] Preferably, an elastic sheet is fixedly connected inside the plastic base, and the elastic sheet is fixedly connected to the bottom of the pressing block.

[0015] Compared with the prior art, this utility model provides a sand barrier bag that can prevent it from being washed away, and has the following beneficial effects:

[0016] This sand barrier bag, designed to prevent it from being washed away, works by using a plastic base, channel one, pressing block, and channel two together. When securing the tightening rope surface, simply moving the pressing block upwards offsets channel two from channel one. This increased friction between channel one and channel two and the tightening rope surface, thus securing both ends of the tightening rope. This avoids the cumbersome process of binding the ends of the tightening rope together, further improving the installation efficiency of the unsealed portion of the sand barrier bag.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Example 1:

[0024] Reference Figures 1-3 A sand barrier bag designed to prevent sand from being washed away includes a sand barrier bag body 1. At least one end of the sand barrier bag body 1 is not sealed. A limiting sleeve 2 is provided at the unsealed end of the sand barrier bag body 1. A tightening rope 3 is provided inside the limiting sleeve 2. A fixing mechanism 4 is provided on the surface of the tightening rope 3. The fixing mechanism 4 is used to lock the surface of the tightening rope 3. The fixing mechanism 4 includes a plastic seat 41 fitted on the surface of the tightening rope 3. A channel 42 is opened on the surface of the plastic seat 41. A pressing block 43 is slidably connected inside the plastic seat 41. A channel 44 is opened on the surface of the pressing block 43. The tightening rope 3 passes through the channel 42 and the channel 44. An elastic piece 45 is fixedly connected inside the plastic seat 41. The elastic piece 45 is fixedly connected to the bottom of the pressing block 43.

[0025] In this invention, sand is first filled into the sand barrier bag body 1. Since one end of the sand barrier bag body 1 is sealed, the sand will not escape from the sealed port of the sand barrier bag body 1. When a certain amount of sand is filled into the sand barrier bag body 1, the two ends of the tightening rope 3 inside the limiting sleeve 2 are tightened. Then, the two ends of the tightening rope 3 are tied together to fix them, thereby shrinking and sealing the unsealed end of the sand barrier bag body 1 to prevent the sand filled into the sand barrier bag body 1 from escaping from the other end. With the setting of the surface fixing mechanism 4 of the tightening rope 3, the two ends of the tightening rope 3 can be fixed, avoiding the cumbersome problem of tying the two ends of the tightening rope 3 together.

[0026] Through the channel 42 inside the plastic base 41 and the channel 44 inside the pressing block 43, the two ends of the tightening rope 3 can pass through the channels 42 and 44 respectively. When it is necessary to fix the surface of the tightening rope 3, simply move the pressing block 43 upward to offset the channel 44 from the channel 42. The angle offset between the channels 42 and 44 increases the friction between them and the surface of the tightening rope 3, thereby fixing the two ends of the tightening rope 3 and preventing the two ends of the tightening rope 3 from slipping. The problem of cumbersome binding of the ends can be solved by pressing down the pressing block 43 inside the plastic seat 41 when it is necessary to loosen the tightening rope 3. This will bring the angles of channel 1 42 and channel 2 44 to the same axis position. At this time, there will be no friction between channel 1 42 and channel 2 44 and the tightening rope 3, so the tightening rope 3 can be easily loosened. After the tightening rope 3 is loosened, the unsealed port of the sand barrier bag body 1 can be opened. With the setting of the elastic piece 45, channel 2 44 can be reset or compressed.

[0027] Example 2:

[0028] Reference Figures 1-3 Similar to Example 1, but further: the bottom of the sand barrier bag body 1 is provided with protrusions 5, and the number of protrusions 5 is multiple sets of equidistant arrangement; the surface of the sand barrier bag body 1 is provided with grooves 6, and the number of grooves 6 is multiple sets of equidistant arrangement; the two sides of the sand barrier bag body 1 are provided with connecting rings 7, and the number of connecting rings 7 is multiple sets; the material of the sand barrier bag body 1 is a biodegradable flexible fabric, and the flexible fabric of the sand barrier bag body 1 is non-woven fabric.

[0029] With the protrusions 5 on the bottom of the sand barrier bag body 1, when the sand barrier bag body 1 is placed on the sand, the side with the protrusions 5 facing down can be inserted into the sand, thereby increasing the pull-out resistance of the bottom of the sand barrier bag body 1 and preventing the sand barrier bag body 1 from being washed away by the wind. The multiple sets of protrusions 5 further increase the friction between the sand barrier bag body 1 and the sand, further improving the stability of the installation. With the grooves 6, when two sets of sand barrier bag bodies 1 are stacked, the bottom protrusions 5 of one set of sand barrier bag bodies 1 can be installed in the grooves on the top of the other set of sand barrier bag bodies 1. Inside the groove 6, the protrusion 5 is installed inside the groove 6 to strengthen the connection between the two sets of sand barrier bag bodies 1 and prevent the two sets of sand barrier bag bodies 1 from easily separating. At the same time, with the setting of the connecting ring 7, the anchor nail can be inserted into the sand through the connecting ring 7 to further improve the firmness of the sand barrier bag body 1. Furthermore, with multiple sets of connecting ring 7, multiple sets of connecting ring 7 can be connected through nylon rope, which can further improve the connection between the two sets of sand barrier bag bodies 1. The sand barrier bag body 1 is made of biodegradable flexible fabric, which can reduce environmental pollution. The flexible fabric is non-woven fabric, which has better degradation efficiency.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
