Description

Technical Field

[0001] This utility model relates to the field of flood control device technology, specifically a filler-type reservoir flood control bag. Background Technology

[0002] As is well known, during flood season, it is necessary to reinforce dikes and riverbanks. Flood control bags are the most commonly used reinforcement components. For example, patent number CN201710428667.5 discloses a flood control sandbag, which includes: a bag body; a bottom handle located at the bottom of the bag body; a bottom through hole on each side of the bottom handle; a top handle located at the top of the bag body, the top handle having a hollow cavity with an opening at the top, the bag opening being located within the hollow cavity of the top handle; a top through hole on each side of the top handle; and a handle strap, which is wrapped between the bottom through hole and the top through hole on the same side. This practical handle strap facilitates manual handling of the bag body, and the top handle effectively protects the bag opening, preventing the bag opening rope from loosening due to manual grasping, thus ensuring the efficiency of dike reinforcement and improving the stability of the dike reinforcement.

[0003] The existing flood control bags have the following shortcomings when stacked and used:

[0004] During the filling process, the bag opening must be manually opened to fill it with flood control materials such as mud and sand. This method is not only labor-intensive and inefficient, but it also severely affects the filling speed and delays precious flood control opportunities during the race against time in flood control and rescue operations.

[0005] During handling, the lack of a reasonable design at the bag opening resulted in an insufficient contact area between the hands and the bag opening. This caused workers to experience significant pressure on their hands when handling the flood control bags, making it difficult to grip them. This not only increased the difficulty and physical exertion of handling the bags but also made them prone to falling due to unstable grips, thus affecting handling efficiency.

[0006] Currently, flood control bags are mainly secured with ropes. However, this method is highly unstable. When manually grasping the bag opening, the ropes can easily loosen or come off due to the force exerted by the hands and the slippery conditions. Once the ropes come off, the flood control materials inside the bag will leak out, which not only reduces the effectiveness of the flood control bag but also requires refilling and retying, further wasting manpower and time. Utility Model Content

[0007] Technical problems to be solved

[0008] To address the shortcomings of existing technologies, this utility model provides a fillable reservoir flood control bag that is more convenient to fill, has improved stability during transportation, and effectively prevents the binding ropes from coming off.

[0009] Technical solution

[0010] To achieve the above objectives, this utility model provides the following technical solution: a filler-type reservoir flood control bag, comprising a bag body, a storage strap at the bag opening, a storage cavity inside the storage strap, and a water-expandable filler filling material inside the storage cavity. After the filler filling material expands when it comes into contact with water, it can open the bag opening, increase the force-bearing area of ​​the hand at the bag opening, and prevent the binding rope of the bag body from falling off.

[0011] Furthermore, the bag body is provided with a connecting strap, which forms a closed loop structure with the bag body.

[0012] Furthermore, the connecting strip has a storage cavity II inside.

[0013] Furthermore, the interior of the storage cavity two is filled with a water-swellable filler, which expands upon contact with water and can stretch the connecting strip.

[0014] Furthermore, the connecting strip is made of a flexible and water-permeable material.

[0015] Furthermore, the storage strip is made of a flexible and water-permeable material. Beneficial effects

[0016] Compared with the prior art, this utility model provides a filler-type reservoir flood control bag, which has the following beneficial effects:

[0017] This type of filler-type reservoir flood control bag has a storage bag at the opening, and the inside of the storage bag is filled with rainwater-expandable filler, which has the following significant effects:

[0018] 1. Upon contact with moisture, the filler expands rapidly, automatically opening the bag. This design eliminates the need for traditional manual bag opening, improving the efficiency of flood control material filling. Rescue personnel no longer need to spend extra effort opening the bag, allowing them to dedicate more time and energy to quickly filling flood control materials such as mud and sand, significantly improving the overall efficiency of flood control operations and saving valuable time in flood control and rescue efforts.

[0019] 2. After the filler expands upon contact with water, the structure at the bag opening becomes more compact, significantly increasing the contact area between the hand and the bag opening. This makes it easier and more stable for workers to grip the flood control bags when handling them, significantly reducing the pressure on their hands. This not only reduces physical exertion during handling but also lowers the risk of the bags falling due to an unstable grip, thereby improving the safety and efficiency of handling and ensuring that flood control supplies can be transported quickly and smoothly to designated locations.

[0020] 3. After the filler inside the storage bag expands, it can tightly wrap around the binding rope at the bag opening, effectively preventing the rope from loosening or falling off during manual operation or handling. This feature greatly improves the sealing reliability of the flood control bag, ensuring that the flood control materials inside the bag will not leak due to problems with the binding rope.

[0025] 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.

[0026] Please see Figure 1-3 This utility model discloses a fillable reservoir flood control bag, comprising a bag body 1, with a storage strap 2 at the bag opening. The storage strap 2 is made of a flexible and water-permeable material. The storage strap 2 can be sewn, glued, or integrally formed at the bag opening of the bag body 1. Alternatively, the edge of the bag opening of the bag body 1 can be folded inward or outward and then connected to the bag body 1 (by gluing or sewing), so that the interior of the storage strap 2 forms a storage cavity 3 with a certain storage space. The storage cavity 3 is filled with a water-expandable filler 4. After the filler 4 expands when it comes into contact with water, it can open the bag opening of the bag body 1 to facilitate the filling of flood control materials. At the same time, it increases the force-bearing area for the user's hand to grip at the bag opening, and when the binding rope is tied below the storage strap 2, it prevents the binding rope of the bag body 1 from falling off from the opening of the bag body 1.

[0027] Furthermore, the bag body 1 is provided with a connecting strap 5, which is made of a flexible and water-permeable material. Its connection method can be the same as that of the storage strap 2 mentioned above. The connecting strap 5 and the bag body 1 form a closed loop structure, so that it can be put on other items. The inside of the connecting strap 5 is provided with a storage cavity 6, which is filled with a water-expandable filler 7. After the filler 7 expands when it comes into contact with water, it can open the connecting strap 5. At this time, an opening is formed between the connecting strap 5 and the bag body 1, which makes it easy for the user to put their hand into the opening of the connecting strap 5, or to put a rope or post into the opening of the connecting strap 5, and also increases the force-bearing area between the connecting strap 5 and the user's hand.

[0028] Both filler 1 (4) and seasoning 2 (7) are made of water-swellable materials, such as the absorbent materials used in diapers.

[0029] In summary, this type of fillable reservoir flood control bag, when in use, places the bag body 1 in the filling position. If it rains, no additional water is needed; if it's sunny, water must be prepared. Ensure the water-expanding filler 4 inside the storage chamber 3 is fully in contact with water. After a short wait, the filler 4 begins to expand upon contact with water, gradually opening the bag opening. Once the bag opening is fully open, use a tool (such as a shovel) to quickly shovel mud and sand into the bag body 1.

[0030] Securely wrap the rope around the bag opening and below the storage strap 2, wrap it several times and tie it tightly. The expanded storage strap 2 will act as a barrier to prevent the rope from easily coming off.

[0031] Hold the bag opening below the connecting strap 5. The increased contact area at the bag opening, coupled with the restraining effect of the connecting strap 5, makes gripping easier and more stable. Smoothly lift the flood control bag and move it to the designated storage area or onto a transport vehicle.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
