Description

Technical Field

[0001] This utility model relates to the field of river environmental protection equipment technology, and more specifically to a one-way enclosure module. Background Technology

[0002] In existing waterways, there is usually a flowing river with an inlet and an outlet. When the water entering at one inlet is sewage, a barrier fabric needs to be installed in the middle of the waterway to prevent the sewage-side water from flowing into the clean-side waterway. However, this barrier fabric also blocks the flow of water from the clean-side waterway to the sewage-side waterway, causing the water flow in this area to completely stagnate and affecting the water flow. In particular, if the goal is to allow clean water to flow into the sewage-side waterway to purify the sewage-side water quality, the barrier fabric cannot achieve this. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a one-way enclosure module that can block the flow of water from the sewage end to the clean end, while ensuring that the water flow from the clean end to the sewage end, so as to purify or dilute the sewage at the sewage end and meet the needs of use.

[0004] The solution of this utility model to the aforementioned technical problem is:

[0005] A one-way enclosure module includes a barrier fabric with a central through hole formed on the barrier fabric, and a filter screen is fixed to the front wall of the barrier fabric and covers the central through hole.

[0006] An intercepting patch is fixed on the rear wall of the barrier fabric. There is a flow channel between the intercepting patch and the barrier fabric. The flow channel is connected to the central through hole, and the intercepting patch covers the central through hole.

[0007] A transverse thickening strip is fixed to the middle of the rear wall of the barrier fabric. Multiple tension ropes are fixed to the transverse thickening strip and the barrier fabric. The other end of the tension rope is fixed to the filter screen.

[0008] The upper and lower parts of the left and right sides of the interception patch are fixedly connected to the blocking fabric in a bent-angle connection state.

[0009] The upper, lower, left, and right parts of the middle section of the intercepting patch are fixedly connected to the blocking fabric in a bent strip connection state; a flow channel is formed between each two adjacent bent strips, and the outer end of the flow channel faces the corresponding bending angle.

[0010] The outstanding effect of this utility model is:

[0011] It can be made by sewing together multiple barrier fabrics to form an isolation sheet, which can prevent water from the sewage end from entering the clean end, while ensuring that water from the clean end flows to the sewage end, so as to purify or dilute the sewage at the sewage end and meet the usage requirements.

[0016] For example, see below. Figures 1 to 4 As shown, a one-way enclosure module includes a barrier fabric 10, on which a central through hole 11 is formed. In this embodiment, the central through hole 11 is rectangular. A filter mesh 12 is fixed to the front wall of the barrier fabric 10 by sewing, bonding or pressing and covers the central through hole 11.

[0017] An intercepting patch 20 is fixed on the rear wall of the barrier fabric 10. There is a flow channel 1 between the intercepting patch 20 and the barrier fabric 10. The flow channel 1 communicates with the central through hole 11. The intercepting patch 20 covers the central through hole 11.

[0018] Furthermore, a transverse thickening strip 13 is fixed to the middle of the rear wall of the barrier fabric 10, and multiple tension ropes 2 are fixed to the transverse thickening strip 13 and the barrier fabric 10. The other end of the tension rope 2 is fixed to the filter screen 12.

[0019] Furthermore, the upper and lower parts of the left and right sides of the intercepting patch 20 are fixedly connected to the blocking fabric 10 at a bending angle 30.

[0020] Furthermore, the upper, lower, left and right parts of the middle of the intercepting patch 20 are fixedly connected to the blocking fabric 10 in a connection state of bending strips 40; a flow channel 1 is formed between each two adjacent bending strips 40, and the outer end of the flow channel 1 faces the corresponding bending angle 30.

[0021] Furthermore, the upper and lower parts of the left and right sides of the intercepting patch 20 are pressed and fixed to the blocking fabric 10 at a bending angle 30, or fixed with adhesive or sewn.

[0022] Furthermore, the upper, lower, left, and right parts of the middle of the interceptor patch 20 are pressed and fixed to the barrier fabric 10 in a connected state of bending strip 40, or fixed with adhesive or sewn.

[0023] Furthermore, the opening of the bending angle 30 faces outward, the opening of the bending strip 40 faces outward, the included angle of the bending angle 30 and the bending strip 40 is 90 degrees, and the outer end of the flow channel 1 faces the tip of the included angle of the corresponding bending angle 30.

[0024] Furthermore, the intercepting patch 20 and the blocking fabric 10 at the middle of the flow channel 1 are fixed by pressing, adhesive, or sewing together in a strip-shaped manner.

[0025] In this embodiment, the appropriate fabric can be selected according to different interception needs. For example, when it is necessary to ensure that the sewage flow of the river cannot enter the clean end, the blocking fabric 10 and the interception patch 20 are both made of PVC waterproof fabric.

[0026] like Figure 4 As shown, when in use, multiple units of this embodiment are fixed by sewing or high-temperature pressing to form a whole isolation sheet. Then, it is placed in a river to block the flow of water from the sewage end and the clean end. At this time, a bag body needs to be sewn on the top of the isolation sheet, and a float or float block is built into the bag body. A lower bag body needs to be sewn on the bottom of the isolation sheet, and a counterweight block is built into the lower bag body, so that the lower part of the isolation sheet contacts the bottom of the river, while the upper part of the isolation sheet floats on the water surface to achieve the barrier.

[0027] Alternatively, multiple through holes can be made on a single sheet of PVC waterproof fabric. Half of a zipper is sewn onto the inner wall of each through hole, and the other half of a zipper is sewn onto the outer wall of the corresponding through hole in this embodiment. The two are connected by pulling the zipper head together. In this embodiment, the corresponding through holes are covered. A bag body needs to be sewn onto the top of the PVC waterproof fabric. The bag body contains a float or float block. A lower bag body needs to be sewn onto the bottom of the isolation sheet. The lower bag body contains a counterweight block, so that the lower part of the isolation sheet contacts the bottom of the river, while the upper part of the isolation sheet floats on the water surface, thus achieving a barrier (this structure is not shown in the attached drawings).

[0028] When in use, as the wastewater flows towards the clean end, the interceptor patch 20 presses against the back wall of the barrier fabric 10, blocking the central through hole 11 and the flow channel 1, preventing wastewater from passing through. When the clean water flows, it is filtered through the filter screen 12 (which prevents aquatic organisms such as fish and shrimp from entering the wastewater end) and flows out from the central through hole 11, pushing the interceptor patch 20 backward. This creates a gap between the interceptor patch 20 and the back wall of the barrier fabric 10, opening the corresponding flow channel 1. At this time, the water can flow out from the flow channel 1 between the two and enter the wastewater end to purify or dilute the water at the wastewater end.

[0029] When the interceptor patch 20 is stretched backward, the tension of the rope 2 is used to prevent the two from spreading too much, thus ensuring a firm connection between them.

[0030] When an overall filtering barrier is required, both the barrier fabric 10 and the interception patch 20 are made of woven fabric, which can be plastic woven fabric such as PET woven fabric.

[0031] Its specific structure is the same as the structure mentioned above. However, when it is in use, it will not completely block the sewage flow. Instead, it will filter the sewage, blocking particulate matter in the sewage, while the liquid in the sewage will pass through the entire isolation plate to enter the clean end.

[0032] The clean end is isolated by a whole piece, which is the same as the above. Everything else is the same, so I will not go into details. This method is suitable for use when the pollutants in the sewage end are large particulate matter impurities.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
