[0003] After searching, the Chinese patent announcement number: CN116479817A discloses a segmented cofferdam diversion equipment for water conservancy project construction. The bottom end is fixed by inserting the positioning parts and the auxiliary stabilizing parts into the riverbed. The auxiliary stabilizing parts and the plug-in positioning parts form a symmetrical triangular structure, which makes the main plate frame and the riverbed more stable; the reinforcing stabilizing parts are arranged to transfer the force of the water flow impacting the load-bearing panel to the fixed connecting parts through the connecting columns, and finally the balancing positioning parts are subjected to a downward pressing force to ensure that the main plate frame is not easy to tilt to the right, and at the same time, the direct impact force of the lower turbulence on the main plate frame is buffered, making the overall equipment more stable; as the upstream water continues to flow down, the balancing positioning parts are pressed by the mud and sand rushed down from the upstream, and the balancing positioning parts and the arranged supporting positioning parts jointly stabilize the main plate frame.

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0038] Reference Figure 1 and Figure 4 The utility model provides an embodiment: a segmented cofferdam diversion device for water conservancy project construction, including a hollow base 1 and a transmission belt 6, a first screw rod 3 is rotatably connected to the front end of the top left side of the hollow base 1, the middle and lower part of the first screw rod 3 penetrates the hollow base 1, and a plurality of second screw rods 4 are rotatably connected to the inner top of the hollow base 1 at equal intervals, the outer sides of the first screw rod 3 and the second screw rod 4 are fixedly connected to pulleys 5, and the plurality of pulleys 5 are connected by transmission belts 6, and the middle and lower parts of the outer sides of the first screw rod 3 and the second screw rod 4 are threadedly connected to movable piles 7, and the bottom ends of the movable piles 7 penetrate the hollow bottom A baffle plate 8 is fixedly connected to the middle of the top of the hollow base 1, a plurality of support plates 15 are fixedly connected to the front and rear sides of the top of the hollow base 1 at equal distances, one side of the plurality of support plates 15 is fixedly connected to the front and rear sides of the baffle plate 8 respectively, a plurality of water inlet holes 9 are evenly opened in the middle of the front and rear sides of the hollow base 1, a cavity 10 is opened inside the hollow base 1, an alarm mechanism 2 is arranged on the top of the baffle plate 8, a slider 11 is fixedly connected to the front and rear sides of the movable pile 7, a plurality of slide bars 12 are evenly fixedly connected around the inner top of the hollow base 1, and the plurality of slide bars 11 are respectively slidably connected to the outer sides of the corresponding slide bars 12;
[0039] Specifically, when the first screw rod 3 is rotated, the pulley 5 on the outside thereof will rotate accordingly, and the pulley 5 on the second screw rod 4 will also rotate closely through the transmission belt 6, so that the second screw rod 4 starts to rotate driven by the transmission belt 6, and as the first screw rod 3 and the second screw rod 4 rotate, the movable piles 7 installed thereon begin to play a role. These movable piles 7 will gradually move downward with the rotation of the first screw rod 3 and the second screw rod 4 until they are deeply inserted into the river bottom. This process can stabilize the foundation of the device. When it rains and the water level of the river rises, the water flows smoothly into the inside of the baffle 8 through the water inlet 9. As the water flows continuously, the overall weight of the baffle 8 gradually increases, which makes the baffle 8 more evenly stressed in the water. This uniform stress not only enhances the stability of the baffle 8, but also further improves the stability of the entire device in the river water.
[0040] Reference Figure 1 , Figure 2 and Figure 3The alarm mechanism 2 includes a limit block 201, and the two limit blocks 201 are respectively fixedly connected to the left and right sides of the inside of the cavity 10. The top of the two limit blocks 201 is provided with a same movable plate 202. The left and right ends of the inner top of the cavity 10 are fixedly connected with a switch 203. A button 204 is provided at the bottom of the switch 203. A T-shaped rod 205 is fixedly connected to the bottom of the button 204. A spring 206 is provided on the outside of the T-shaped rod 205. One end of the spring 206 is fixedly connected to the bottom of the button 204, and the other end of the spring 206 is fixedly connected to the bottom of the T-shaped rod 205. A hollow box 207 is fixedly connected to the middle of the top of the baffle 8, and an alarm 208 is fixedly connected to the inner bottom of the hollow box 207. The switch 203 is electrically connected to the alarm 208. The size of the movable plate 202 matches the internal size of the cavity 10.
[0041] Specifically, when water flows into the baffle 8 through the water inlet 9, as the water level continues to rise, the movable plate 202 will gradually rise due to the buoyancy of the water, and as the movable plate 202 rises, it will gradually squeeze the T-bar 205, and then push the button 204. In this process, the pressure on the button 204 gradually increases. When the preset threshold is reached, the button 204 will trigger the alarm 208 and emit a loud alarm. This design is not only simple and effective, but also can quickly remind the staff to pay attention to the abnormal increase in the water level of the water body. The sound of the alarm 208 can not only attract the attention of the staff, but also clearly indicate the location of the abnormal water level of the water body. This instant feedback mechanism enables the staff to respond quickly and take appropriate measures to prevent water leakage or overflow, thereby ensuring the normal operation of the entire system.
[0042] Reference Figure 1 and Figure 2 The alarm mechanism 2 includes a box door 209, which is arranged at the front side of the hollow box 207. The upper and lower sides of the front end of the box door 209 are provided with a rotating shaft 210. The box door 209 is rotatably connected to the hollow box 207 through the rotating shaft 210. A handle 211 is fixedly connected to the left side of the front end of the box door 209;
[0043] Specifically, the box door 209 can be opened conveniently through the handle 211 to inspect and maintain the components inside.
[0044] Reference Figure 1 , warning signs 16 are fixedly connected to the front, rear, left and right ends of the baffle 8;
[0045] Specifically, the warning sign 16 can serve as a warning to the staff.
[0046] Reference Figure 1 and Figure 2 The right bottom of the baffle 8 is connected to a liquid outlet pipe 13, and the right end of the liquid outlet pipe 13 is threadedly connected to a sealing cover 14;
[0047] Specifically, the water source inside the baffle 8 can be discharged through the liquid outlet pipe 13 , and the provided sealing cover 14 can seal the baffle 8 .
[0048] Working principle: When using the cofferdam device, first carry it to the water surface where the cofferdam needs to be installed, then rotate the first screw rod 3, the pulley 5 on its outer side will rotate accordingly, and the pulley 5 on the second screw rod 4 will also rotate through the transmission belt 6, thereby driving the second screw rod 4 to rotate. At this time, the movable piles 7 on the first screw rod 3 and the second screw rod 4 will move downward and insert into the river bottom, so that the device can be fixed more stably. When encountering rainy weather, the water flow will rise accordingly. At this time, the water flow will enter the baffle 8 through the water inlet hole 9, which can increase the overall weight of the baffle 8 and make it more evenly stressed, thereby improving the overall stability of the device. , which can meet the needs of users, and when water flows into the baffle 8, the movable plate 202 will rise with the buoyancy of the water until it squeezes the T-bar 205, and the button 204 will be squeezed to turn on the alarm 208. At this time, the alarm 208 will make a sound to remind the staff that the water level has risen abnormally, so as to ensure that the staff can deal with the water in time to prevent water leakage. After the water level drops, the water source inside the baffle 8 will be released through the liquid outlet pipe 13. At this time, the spring 206 will release the squeezed force and drive the movable plate 202 to rebound, so that the alarm 208 can be turned off, thereby improving the practicality of the device.
[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
