Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water conservancy engineering technology, specifically relating to a protective device for preventing erosion of river channels and riverbanks. Background Technology
[0002] Rapid and safe handling of dike breaches during the flood season is essential for ensuring the safety of river flood passage. Existing river management methods typically involve fixing protective devices to the surface of the dike bank to prevent flooding. For example, protective netting laid on the dike surface is often pre-installed, but its effectiveness is low. Another method involves quickly fabricating gabions on-site and deploying them to the breached dike. However, gabions have limited volume and coverage, and the lack of connection between them makes them susceptible to being washed downstream, failing to protect the dangerous dike and incurring excessive costs. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a flexible protection device for riverbank erosion prevention, which has good integrity and erosion resistance, and can be moved and quickly protect the dike.

A flexible fabric is stretched between the positioning telescopic rod and the traction telescopic rod, and the flexible fabric covers the river embankment.
[0006] In the aforementioned flexible protective device for preventing erosion of riverbanks, the bottom of both the positioning telescopic rod and the traction telescopic rod is a spearhead that can be easily inserted into the riverbed.
[0007] The aforementioned flexible protective device for preventing erosion of riverbanks and waterways has several counterweights spaced at the bottom of the flexible fabric.
[0008] The aforementioned flexible protective device for preventing erosion of riverbanks and channels uses a counterweight ball as its weight.
[0009] The flexible protective device for preventing erosion of riverbanks mentioned above uses fiber cloth as the flexible fabric.
[0010] The aforementioned flexible protective device for preventing erosion of river channels and riverbanks has the same structure for both the positioning telescopic rod and the traction telescopic rod, which are both composed of multiple rods connected together and fixed by a screw inserted at the connection point.
[0011] The aforementioned flexible protective device for preventing erosion of riverbanks has a ring buckle at one end of the screw, and the other end is fixed by a nut after passing through the joint of two rods. Several binding straps or several ring holes are provided on both sides of the flexible cloth. The binding straps are tied to the ring buckle at the end of the screw, or the ring holes of the flexible cloth are engaged with the ring buckle at the end of the screw.
[0012] Compared with the prior art, the present invention has the following technical effects:
[0013] The positioning telescopic rod and traction telescopic rod of this invention can be quickly fixed to the riverbed at the lower part of the embankment. The flexible fabric is easy and quick to tension, and the flexible fabric has good erosion resistance. This invention can deploy the device for protection at any time when protecting the embankment, and can be retrieved for later use after use.

[0021] The following is combined with Figure 1-2 The specific implementation method of this utility model is described in detail.
[0022] A flexible protective device for preventing erosion of riverbanks includes a positioning telescopic rod 3 upstream of the river embankment and a traction telescopic rod 5 downstream of the river embankment. A flexible cloth 4 is stretched between the positioning telescopic rod 3 and the traction telescopic rod 5, and the flexible cloth covers the river embankment.

[0026] The flexible protective device for preventing erosion of river channels and riverbanks described in this utility model uses fiber cloth as the flexible fabric.
[0027] The flexible protective device for preventing erosion of river channels and riverbanks described in this utility model has the same structure for the positioning telescopic rod and the traction telescopic rod, both of which are composed of multiple rods connected together. Bolt holes are provided at the connection points of the rods, and a screw is inserted into the bolt hole of the corresponding rod at the connection point to fix two adjacent rods.
[0028] The flexible protective device for preventing erosion of river channels and riverbanks described in this utility model has an annular buckle 2 at one end of the screw, and the other end is fixed by a nut after passing through the joint of two rods. Several binding straps or several annular holes are provided on both sides of the flexible cloth. The binding straps are tied to the annular buckle at the end of the screw, or the annular holes of the flexible cloth are engaged with the annular buckle at the end of the screw.
[0029] The working process of this utility model is as follows:
[0030] This utility model is a device with a large laying range, strong integrity and erosion resistance, including a positioning telescopic rod upstream of a dangerous river embankment, a flexible cloth that unfolds and covers the unknown, and a traction telescopic rod that stretches and unfolds the flexible cloth downstream.

The head of the first rod is connected to the gun tip, which can be inserted into the riverbed for positioning. The gun tip is connected to the rod and fixed by a screw. One end of the screw is a ring buckle, and the other end is fixed by a nut.
[0032] The flexible fabric is a flexible fiber fabric with multiple annular holes along one end of its width. The spacing between the annular holes is the same as the spacing between the annular buckles of the telescopic rod.
[0033] The telescopic rods are connected in sequence, and the flexible fiber cloth is also connected to the telescopic rod's ring buckle in sequence to form a whole.
[0034] The telescopic rod connecting the flexible fiber cloth extends upstream of the embankment protection location and is fixed to the riverbed, allowing the flexible fiber cloth to gradually unfold along the embankment. At regular intervals, a weighted ball is attached to the end of the flexible fiber cloth that is submerged in the water, stretching the flexible fiber cloth as it sinks. Figure 3 As shown.
[0035] The end of the fully unfolded flexible fiber cloth has the same structure as the upstream end, and the annular holes on the cloth are connected to the annular buckles of the downstream telescopic rod to form a whole.
[0036] The downstream telescopic boom has the same structure as the upstream boom, and after being connected to the flexible fiber cloth, it is inserted into the bottom of the downstream river channel. The embankment is protected by the unfolded flexible fiber cloth.
[0037] This utility model allows for the deployment of the device whenever needed to protect a water-damaged embankment 7, and the device can be retrieved for later use after the protection is completed. In addition, its greatest advantages are its rapid mobility and comprehensive protection.
[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
