Description

Technical Field

[0001] This application relates to a riverbed erosion prevention device. Background Technology

[0002] A river channel refers to the waterway through which river water flows. Because river water itself erodes the river channel, various types of protective devices are needed. The most common protective device is a retaining structure installed across the river channel. Existing retaining structures have two main problems: first, they primarily serve an isolation function, which is insufficient to stabilize the soil, making soil erosion more likely; second, many existing river channels experience fluctuations in water level due to seasonal factors. These fluctuations mean that in some river channels, planting grass during the dry season can help stabilize the soil, but existing retaining structures are either unable to withstand the water flow or are difficult to plant grass. Therefore, it is necessary to modify the river channel protective devices to address these issues. Utility Model Content

[0003] To address the aforementioned problems, this application proposes a river erosion prevention device, comprising several protective shells arranged in abutment. Connecting chamfers are provided at each corner of the protective shells, and hook-up rings are provided on the protective shells with connecting chamfers. Adjacent hook-up rings are connected by annular connecting rods. Several positioning parts are provided on the outer side of the protective shells, and adjacent protective shells are connected by positioning latches through these positioning parts. By providing connecting chamfers and hook-up rings on the sides of the protective shells, this application can provide auxiliary connection for the protective shells, ensuring the stability of the structure and its placement.

[0004] Preferably, the bottom of the protective shell is provided with a bottom plate, and the bottom plate has several bottom through holes. In order to improve the resistance to the impact of external water flow, this application provides a bottom plate inside the protective shell to improve the protection of the bottom soil. In addition, the design of auxiliary ribs can ensure that its bottom can resist external impact.

[0005] Preferably, a number of cross-arranged auxiliary ribs are provided on the bottom plate, and a number of transverse through holes are provided on the auxiliary ribs.

[0006] Preferably, the transverse through hole is located at the bottom of the auxiliary rib.

[0007] Preferably, the bottom through hole is located on the side of the bottom plate adjacent to the protective housing.

[0008] Preferably, the protective housing includes two opposing first side plates and second side plates, with a third side plate and a fourth side plate respectively disposed between the first and second side plates; a first mounting groove is provided in the middle of the first side plate, and a first snap-fit ​​protrusion is provided in the middle of the second side plate to cooperate with the first mounting groove; a second mounting groove is provided in the middle of the third side plate, and a second snap-fit ​​protrusion is provided in the middle of the fourth side plate to cooperate with the second mounting groove. This application, by having the first snap-fit ​​protrusion cooperate with the first mounting groove of an adjacent protective housing, and the second mounting groove cooperate with the second snap-fit ​​protrusion of other adjacent protective housings, allows for rapid structural assembly, forming the positioning part described in this application, and possesses excellent structural stability, preventing displacement during use.

[0009] Preferably, the first and second snap-fit ​​protrusions have the same shape, and their cross-sectional areas are gradually reduced in the direction away from the protective housing.

[0010] Preferably, the cross-sectional area of ​​the first snap-fit ​​protrusion is an isosceles trapezoid.

[0011] Preferably, the cross section of the connecting chamfer is an isosceles right triangle;

[0012] The connecting chamfers are respectively set at the connection between the first side plate and the second side plate, the connection between the second side plate and the third side plate, the connection between the third side plate and the fourth side plate, and the connection between the fourth side plate and the first side plate.

[0013] This application can bring the following beneficial effects:

[0014] 1. This application provides connecting chamfers and hook rings on the side of the protective housing, which can serve as auxiliary connections for the protective housing and ensure the stability of the structure and its placement.

[0015] 2. In order to improve the resistance to external water flow impact, this application sets a bottom plate inside the protective shell to improve the protection of the bottom soil. In addition, the design of auxiliary ribs can ensure that the bottom can resist external impact.

[0016] 3. This application uses a first snap-fit ​​protrusion that engages with the first mounting groove of an adjacent protective housing, and a second mounting groove that engages with the second snap-fit ​​protrusion of other adjacent protective housings. This allows for rapid structural assembly and provides excellent structural stability, preventing displacement during use. Attached Figure Description
