Description

Water-absorbing expansion bag

Technical Field

The utility model is applied to the technical field of flood control and leakage stoppage, and particularly relates to a water-absorbing expansion bag.

Background

Along with extreme abnormal global climate, flood disasters are inevitable in summer in partial areas, life safety and property safety of people are seriously influenced, the prior flood prevention tool is a flood prevention sand bag, sand is filled into the sand bag, then a rope is used for binding the flood prevention sand bag, finally the sand bag is stacked to form a flood prevention wall body, the flood prevention sand bag is not favorable for carrying and recycling due to larger weight, a large amount of manpower is consumed for filling the sand and binding the bag, the opportunity of rescue and relief work is easily delayed, the existing water absorption expansion bags are various, the requirements of flood prevention and leakage stoppage are met to a certain extent, when the bag is immersed in water or is directly drenched in a flood prevention zone, an expanding agent of an inner bag is squeezed at the bottom of the inner bag under the action of gravity, the bag needs to be manually flattened in the stacking process, flood prevention efficiency is seriously influenced, and the flood prevention expansion bags are not connected, the stability of the flood control wall is affected, and therefore, a water-absorbing expansion bag with a net separation structure and a simple structure is needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of overcoming the defects of the prior art and provides the water-absorbing expansion bag with a simple structure and a separation net structure.

The technical scheme adopted by the utility model is as follows: the water-absorbent composite bag comprises an outer bag and an inner bag, wherein the inner bag is connected inside the outer bag, three groups of grid structures are equidistantly connected on the longitudinal section inside the inner bag, a plurality of high-molecular water-absorbent resin particles are uniformly filled inside the inner bag, and the gaps of the grid structures are smaller than the diameter of the high-molecular water-absorbent resin particles.

According to the scheme, the inner bag is divided into four parts through three groups of grid structures, each part is filled with a plurality of high-molecular water-absorbent resin particles, the high-molecular water-absorbent resin particles are super absorbent, when the high-molecular water-absorbent resin particles contact with water, the high-molecular water-absorbent resin particles swell in a short time, the volume expands rapidly, the weight increases along with the increase of the water, the water in the weight which is hundreds of times of the self weight can be absorbed, the weight of the water-absorbent swelling bag after absorbing water is 30KG,

the clearance of graticule mesh structure is less than the diameter size of polymer water absorbent resin granule, graticule mesh structure can prevent effectively that polymer water absorbent resin granule all extrudes in the bottom of inner bag, has reduced the manual work and has flattened the process with the sack, effectively improves the efficiency of controlling water and flood control.

One preferred scheme is that four corners of the outer bag are connected with hemp ropes.

According to the scheme, the hemp ropes are connected to the corners of the outer bag, and the adjacent water-absorbing expansion bags are connected through the hemp ropes, so that the overall strength and the water flow impact resistance of the water-absorbing expansion bags can be improved.

Preferably, the outer bag comprises a sack structure and an all cotton canvas structure.

According to the scheme, the hemp bag structure and the all-cotton canvas structure have good toughness, and the service life of the water-absorbing expansion bag is prolonged.

Preferably, the inner bag comprises a nonwoven cloth bag structure.

One preferred scheme is that the grid structure comprises a chemical fiber cloth bag structure.

Preferably, when a plurality of the water-absorbent polymer resin particles absorb water and swell, the length, width and height of the outer bag are 120cm, 100cm and 50cm, respectively, and the length, width and height of the inner bag are 110cm, 90cm and 50cm, respectively.

One preferable scheme is that an acrylic cotton structure is filled between the outer bag and the inner bag.

According to the scheme, the acrylic cotton structure is filled between the outer bag and the inner bag, the water absorption of the acrylic cotton structure is good, and the stability of the flood control wall body is further improved.

In one preferable embodiment, the loading amount of the water absorbent polymer particles is 500 g.

Detailed Description

As shown in fig. 1 to 3, in this embodiment, the present invention includes an outer bag 1 and an inner bag 2, the inner bag 2 is connected inside the outer bag 1, three groups of grid structures 3 are equidistantly connected to a longitudinal section inside the inner bag 2, a plurality of high polymer water-absorbent resin particles 4 are uniformly filled inside the inner bag 2, and gaps of the grid structures 3 are smaller than the diameter of the high polymer water-absorbent resin particles 4.

In this embodiment, four corners of the outer bag 1 are connected with hemp ropes 5.

In the present embodiment, the outer bag 1 includes a sack structure and an all cotton canvas structure.

In the present embodiment, the inner bag 2 comprises a nonwoven bag structure.

In this embodiment, the grid structure 3 includes a chemical fiber cloth bag structure.

In this embodiment, when a plurality of the water-absorbent polymer beads 4 swell by absorbing water, the length, width and height of the outer bag 1 are 120cm, 100cm and 50cm, respectively, and the length, width and height of the inner bag 2 are 110cm, 90cm and 50cm, respectively.

In this embodiment, an acrylic cotton structure is filled between the outer bag 1 and the inner bag 2.

In this example, the filling amount of the water absorbent polymer particles 4 was 500 g.

The working principle of the utility model is as follows: will the water inflation bag soaks three minutes in the aquatic, because three groups the graticule mesh structure will the inner bag falls into four parts, the graticule mesh structure can prevent effectively the polymer water absorbent resin granule all squeezes in the bottom of inner bag, and is a plurality of every part during the polymer water absorbent resin granule contacts with water, in the short time the swelling of polymer water absorbent resin granule, the weight after the water inflation bag absorbs water is 30KG, the water inflation bag directly piles up in flood control region, will be adjacent at last the outer bag hemp ties the connection.
