In the following description, a lot of specific details are set forth in order to fully understand the present disclosure. However, the present disclosure can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present disclosure, so the present disclosure is not limited by the specific embodiments disclosed below.
[0033] In the description of the present disclosure, it needs to be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like are based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present disclosure. The terms "first", "second" used are for distinguishing one element from another element, and do not have sequential or important meanings. In addition, the following description refers to the drawings, and the same reference signs in different drawings represent the same or similar elements, which will not be repeated here.
[0034] In the present disclosure, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting", "fixing" and the like should be understood broadly, for example, can be fixed connection, can also be detachable connection, or integral; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.
[0035] According to some embodiments of the present disclosure, a dike blocking device is provided, as shown in Figures 1 to 10 The dike blocking device includes a pressing plate 101 and a plurality of vertical insertion rods 102, and the vertical insertion rods 102 are installed at the bottom of the pressing plate 101. The pressing plate 101 is provided with a mounting shaft 202, and the mounting shaft 202 is hinged with a rotating plate 201. One end of the rotating plate 201 is provided with a first torsional spring 206, one end of the first torsional spring 206 is connected with the rotating plate 201, and the other end of the first torsional spring 206 is connected with the mounting shaft 202. A first hole 203 is formed in the rotating plate 201. The first torsional spring 206 makes the rotating plate 201 have a certain buffering capacity. When the water flow is large, the rotating plate 201 is deflected to prevent the rotating plate 201 from being subjected to a large impact force, which causes the device to roll over.
[0036] Therefore, the device is placed at the breach of the embankment, and water flows through the breach. The water flow continuously impacts the rotating plate 201. The surface of the rotating plate 201 is impacted by the water flow. The impact force is perpendicular to the surface of the rotating plate 201. Since the rotating plate 201 is inclined, the impact force has a vertical downward component. The rotating plate 201 transmits the vertical downward component to the pressing plate 101. The pressing plate 101 gradually presses the plurality of vertical insertion rods 102 into the wet soil layer. The plurality of vertical insertion rods 102 inserted into the soil layer help to improve the integrity of the soil and reduce further collapse of the soil. At the same time, the pressing plate 101 is prevented from drifting away. In addition, the pressing plate 101 covers the surface of the soil layer. In combination with the guiding effect of the rotating plate 201 on the water flow, the soil layer is further prevented from being impacted by the water flow. After the device is placed, the rescue personnel successively pile sand and stones on the surface of the pressing plate 101 to further complete the plugging work of the breach. Since the pressing plate 101 and the vertical insertion rod 102 complete the preliminary fixation of the soil, it is beneficial to the accumulation of sand and stones in the breach and provides sufficient time for rescue, thereby reducing the difficulty of plugging.
[0037] It should be noted that there may be vortex flow on the back of the rotating plate 201 (the surface of the rotating plate 201 impacted by the water flow is considered as the front surface). The clockwise rotation of the rotating plate 201 caused by the water flow impacting the front surface of the rotating plate 201 is beneficial to the insertion of the vertical insertion rod 102 into the soil. The counterclockwise rotation of the rotating plate 201 caused by the vortex flow impacting the back of the rotating plate 201 may cause the vertical insertion rod 102 to be pulled out in the opposite direction.
[0038] To further reduce the influence of vortex flow, please refer to Figure 2 , Figure 3 , Figure 6 A baffle 204 is hinged to the side of the rotating plate 201 away from the water flow. The baffle 204 is adjacent to the first hole 203. The baffle 204 is provided with a second hole 205. One end of the baffle 204 is provided with a second torsional spring 207. One end of the second torsional spring 207 is connected to the baffle 204. The other end of the second torsional spring 207 is connected to the rotating plate 201. Therefore, when the rotating plate 201 rotates counterclockwise, the baffle 204 blocks the first hole 203, increasing the area of the front surface of the rotating plate 201 impacted by the water flow, which is beneficial to increasing the water flow impact force on the rotating plate 201, making it easier for the vertical insertion rod 102 to be inserted into the soil layer. When the back of the rotating plate 201 is impacted by the vortex flow and rotates clockwise, the baffle 204 opens under the water flow resistance, reducing the area of the back of the rotating plate 201 impacted by the vortex flow, thereby reducing the influence of the vortex flow and ensuring the normal function of the device.
[0039] In addition, the pressing plate 101 is provided with limiting longitudinal strips 103 for preventing the loss of sand and gravel, the limiting longitudinal strips 103 are provided in plurality and are uniformly distributed on the pressing plate 101, and the pressing plate 101 is further provided with limiting transverse strips 104, the limiting transverse strips 104 are perpendicular to the distribution direction of the limiting longitudinal strips 103, therefore, after the device is placed, the rescue personnel can successively stack sand and gravel on the surface of the pressing plate 101, and the limiting transverse strips 104 and the limiting longitudinal strips 103 greatly increase the stability of the sand and gravel, preventing the sand and gravel from being washed away by the water flow.

[0041] Through the above technical scheme, the dike blocking device provided by the present disclosure is used by placing the device at the dike breach, and the water flow impacts the front surface of the rotating plate 201, due to the inclined arrangement of the rotating plate 201, the impact force generates a vertical downward component force which is transmitted to the pressing plate 101, and the pressing plate 101 continuously presses the plurality of vertical insertion rods 102 into the wet riverbed soil layer, the insertion of the vertical insertion rods 102 improves the integrity of the soil, reduces the soil collapse speed, and fixes the pressing plate 101 to prevent it from drifting, in addition, the pressing plate 101 covers the surface of the soil layer, combined with the guiding effect of the rotating plate 201 on the water flow, the device together protects the underlying soil layer from direct scouring, after the device is preliminarily fixed, the rescue personnel can stack sand and gravel on the surface of the pressing plate 101 to complete the final blocking, and the stability provides a reliable foundation for the sand accumulation, saves time for rescue and reduces the difficulty, the surface of the pressing plate 101 is provided with a plurality of limiting longitudinal strips 103 which are uniformly distributed and a plurality of limiting transverse strips 104 which are perpendicular to the limiting longitudinal strips 103, which is conducive to increasing the stability of the stacked sand and gravel and preventing them from being washed away by the water flow, the filter plate 301 hinged to the side of the rotating plate 201 close to the water flow impact filters the impurities in the water flow, preventing the impurities from blocking the first hole 203, when the rotating plate 201 rotates clockwise and the bottom end of the arc-shaped rod 302 is in contact with the pressing plate 101, the filter plate 301 stops moving, the rotating plate 201 continues to rotate and compresses the reset compression spring 303 to separate the two, the filter plate 301 is completely exposed to the water flow and is washed, realizing the function of automatic cleaning and removing the attached impurities.
