Embodiment Construction

[0027] like figure 1 A multi-net foldable underwater piling noise reduction device shown, including a fixing device, a multi-layer seine noise reduction device, a telescopic lifting device, a power and data feedback device, and a receiving and control device required for sailing

[0028] like figure 2 and 3 As shown, the fixing device 1 includes a fixed plate, which is provided with a powerful hook 3, an infrared receiving device 4, a driving device 5, a telescopic clamp 6 and an elastic rope hook 7, and the strong hook 3 can be connected with the hanging hook on the sea transport ship. The infrared receiving device 4 receives the infrared signal from the ship and transmits it to the driving device 5, and the driving device 5 drives the telescopic clamping plate 6 to move, and then is fixed on the pile foundation.

[0029] like Figure 4 As shown, the power and data feedback device 8 includes an installation platform on which an elastic rope 2, a telescopic clamp 6, an inf...

Abstract

The invention discloses a multi-net type foldable underwater piling noise reduction device and its implementation method, including a fixing device, a power and data feedback device, a telescopic lifting net cage and a control device. The power and data feedback device can be detachably set on the pile foundation on the lower side of the fixing device, and the power and data feedback device can be detachably connected with the telescopic lifting net cage. Each layer of the multi-layer net curtain is equipped with a vertical lifting rod vertically. The power and data feedback device includes an infrared receiver, a battery motor and a Bluetooth signal device. The battery motor drives the horizontal telescopic rod or the vertical telescopic rod according to the signal received from the control device. The Bluetooth signal device collects the noise from the acoustic sensor on the horizontal telescopic rod and feeds it back to the control device. The invention can be used for underwater noise reduction of piling, in order to reduce noise pollution of marine environment.

Description

technical field [0001] The invention relates to a piling noise reduction device and an implementation method. The invention relates to a multi-network foldable underwater piling noise reduction device and an implementation method. Background technique [0002] Now more and more large-scale offshore construction facilities are being built, and the level of marine environmental noise is on the rise. Offshore piling is the foundation of large-scale offshore facility construction, and serious marine environmental noise will inevitably be generated during piling construction. Because most of the time piling produces impact noise, it will cause adverse effects such as nervousness of marine organisms, and have a greater impact on the life and survival of marine organisms and the marine ecological environment. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to provide a multi-net foldable underwater piling noise reduction device to solv...
