Description

Technical Field

[0002] Underwater construction typically involves driving a steel cofferdam underwater to block the surrounding water and prevent water flow and pressure from affecting the normal construction process. The steel cofferdam is usually made up of multiple steel sheet piles, which are driven one by one into the geological layer at the bottom of the water during construction. During the driving of the steel sheet piles, considerable noise may be generated underwater. Excessive noise can affect the marine ecosystem, so it is necessary to install a noise monitoring device underwater.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Example 1

[0022] like Figures 1-5 As shown, an underwater construction noise monitoring device of this embodiment includes a door-shaped base 10, a door-shaped mounting frame 1 is fixedly connected to the upper side of the base 10, and a column 11 is fixedly connected to the mounting frame 1. The column 11 can be installed on an auxiliary device, so that the underwater construction noise monitoring device of this embodiment is in a suspended and fixed state, so that piling operations can be carried out.

[0023] The upper side of the mounting frame 1 is fixedly connected to a hydraulic cylinder 12, the telescopic end of the hydraulic cylinder 12 is fixedly connected to a first electromagnet 13, a gravity block 14 is slidably connected inside the mounting frame 1, and a clamping device 15 is slidably connected to the base 10. The clamping device 15 is a prior art and will not be described in detail here. The clamping device 15 is used to clamp the steel sheet pile 100. A striking plate 16 is provided on the top of the clamping device 15. The gravity block 14 is adsorbed by the first electromagnet 13, and then the first electromagnet 13 and the gravity block 14 are lifted upward by the hydraulic cylinder 12. After the first electromagnet 13 is powered off, the gravity block 14 falls downward under the action of gravity and hits the striking plate 16, causing the clamping device 15 to move downward, thereby driving the steel sheet pile 100 into the geological layer at the bottom of the water.

[0024] A guide device 2 is installed on one side of the mounting frame 1, and a noise monitoring component 3 is installed on one side of the guide device 2. The guide device 2 includes a bottom plate 22 and a top plate 21 fixed to one side of the mounting frame 1, and the bottom plate 22 and the top plate 21 are arranged parallel to each other. A vertically arranged guide shaft 23 is fixedly connected between the bottom plate 22 and the top plate 21, and a slide plate 24 is slidably connected to the guide shaft 23. A connecting block 17 is fixed to one side of the gravity block 14, and a second electromagnet 18 is installed on one side of the connecting block 17. A fixed column 25 is fixedly connected to the upper side of the slide plate 24, and the fixed column 25 is arranged corresponding to the second electromagnet 18. The second electromagnet 18 attracts the fixed column 25, so that the connecting block 17 and the second electromagnet 18 can move up and down during the up and down movement of the gravity block 14.

[0025] The noise monitoring assembly 3 is connected to the slide 24 and includes a rectangular frame 32, which is tilted upward and hinged to the slide 24 via a first connecting plate 31. A conical support block 33 is positioned within the frame 32, with anti-drop rods 37 positioned on either side of the support block 33. The frame 32 is positioned between the two anti-drop rods 37. A float 34 is fixedly connected to the underside of the support block 33. The underside of the float 34 is fixedly connected to a sound collection cover 36 via a suspension rod 35. The sound collection cover 36 houses a noise monitor. This existing noise monitor is used for noise monitoring and will not be described in detail here.

[0026] A wave-beating device 4 is hinged on one side of the bottom plate 22, and the wave-beating device 4 is arranged corresponding to the float 34. The wave-beating device 4 can move the float. The wave-beating device 4 includes a crossbeam 41, and the lower side of the crossbeam 41 is fixedly connected to two vertical beams 42. The two vertical beams 42 are rotatably connected to a water wheel 43. A motor 44 is installed on one side of the vertical beam 42, and the motor 44 is used to drive the water wheel 43 to rotate. The crossbeam 41 is hinged to the bottom plate 22 through a second connecting plate 46, and one side of the vertical beam 42 is fixedly connected to a raised column 45. A push-type switch is installed on the upper end of the raised column 45. The push-type switch is used to control the start and stop of the motor 44. A press plate 38 is installed on one side of the rectangular frame 32. When the press plate 38 contacts the push-type switch, the motor 44 starts, and when the press plate 38 leaves the push-type switch, the motor 44 stops working.

[0027] One side of the base plate 22 is fixedly connected to the backing plate 26, and one side of the slide plate 24 is fixedly connected to the cover plate 20. The backing plate 26 and the cover plate 20 are rotatably connected to the telescopic shaft 27. The second connecting plate 46 and the first connecting plate 31 are both fixed to the telescopic shaft 27. A transmission device is provided on the base plate 22, which is used to rotate the telescopic shaft 27. The transmission device includes a slider 29, a movable beam 210, a gear ring 28, and a rack 211. A plurality of inserts 212 are spaced apart on one side of the movable beam 210. The rack 211 is fixed to the other side of the movable beam 210. The movable beam 210 is fixed to the slider 29. The slider 29 slides in a slot on the upper side of the slide plate 24. The gear ring 28 is fixed to the telescopic shaft 27 and meshes with the rack 211. The lower side of the slide plate 24 is fixedly connected to the insert rod 213. The insert rod 213 is arranged corresponding to the insert block 212, and the lower end of the insert rod 213 is provided with an inclined surface.

[0028] During use, the first electromagnet 13 attracts the weight block 14, which is then lifted upward by the hydraulic cylinder 12. After the first electromagnet 13 is de-energized, the weight block 14 falls downward under the action of gravity and strikes the impact plate 16, causing the clamping device 15 to move downward, thereby driving the steel sheet pile 100 into the geological layer under the water. Simultaneously, underwater noise is monitored during the piling process. The specific monitoring principle is as follows:

[0029] The first electromagnet 13 attracts the gravity block 14 and moves it upward. When the gravity block 14 reaches the highest point, the second electromagnet 18 releases the fixing column 25. After the fixing column 25 is under the adsorption force, the slide plate 24 and the noise monitoring component 3 slide downward along the guide shaft 23 under the action of gravity until the slide plate 24 drops to the lowest point. At this time, the float 34 floats on the water surface. In order to prevent the residual adsorption force of the second electromagnet 18 from affecting the descent of the slide plate 24, a limit column 214 is fixedly connected to the lower side of the top plate 21. When the first electromagnet 13 attracts the gravity block 14 and moves it upward, when the gravity block 14 is about to reach the top, the limit column 214 contacts the fixing column 25. As the gravity block 14 continues to rise, the fixing column 25 is separated from the second electromagnet 18 under the action of the limit column 214, so that the sound collecting cover 36 and the noise monitor are in a drifting state and separated from other components. This prevents the noise from being transmitted along the connecting parts during the piling process, thereby causing inaccurate monitoring results.

[0030] At the same time, during the monitoring process, when the skateboard 24 and the noise monitoring component 3 slide downward along the guide shaft 23 under the action of gravity, until the skateboard 24 drops to the lowest point, the pressing plate 38 contacts the push-type switch, and the motor 44 starts and drives the water wheel 43 to rotate, thereby creating waves on the water surface. Under the action of the waves, the float 34 moves, thereby changing the position of the sound collecting cover 36 and the noise monitor, and constantly changing the monitoring point. If the monitoring value of one of the points reaches the upper limit, it proves that the construction noise needs to be reduced.

[0031] At the same time, when the slide plate 24 and the noise monitoring component 3 slide downward along the guide shaft 23 under the action of gravity, the insertion rod 213 also moves downward and contacts the insertion block 212. Under the action of the inclined surface at the lower end of the insertion rod 213, the insertion block 212 and the movable beam 210 move forward. Under the action of the rack 211 and the gear ring 28, the telescopic shaft 27 rotates, thereby changing the direction of the rectangular frame 32, thereby changing the position of the float 34, and further changing the position of the sound collecting cover 36 and the noise monitor, constantly changing the monitoring point, and further improving the accuracy of monitoring.
