Description

Technical Field

[0001] This invention relates to the field of offshore wind power engineering technology, and in particular to an automatic emission device for corrosive gases from a single pile. Background Technology

[0002] Offshore wind turbine monopile foundations are submerged in the seabed for extended periods, leading to the accumulation of silt inside. Microbial decomposition within this silt produces corrosive gases. These gases can corrode components on the upper part of the tower, affecting the normal operation of internal equipment. Therefore, it is necessary to treat and release these harmful gases from the monopile foundation. Currently, the method for releasing corrosive gases from monopile foundations often involves directly creating ventilation openings in the pile wall. The size, location, and spacing of these openings are fixed, making it difficult to adapt to monopile foundations of different diameters and heights. This lack of adaptability to operating conditions results in inconsistent exhaust performance, potential exhaust dead zones, low exhaust efficiency, and excessive energy consumption and operating costs due to the long operating times required for the wind turbine. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic emission device for corrosive gases from a single pile, which can solve the problem that existing single pile venting methods are difficult to adapt to single pile foundations of different sizes.

[0004] Therefore, the present invention adopts the following technical solution: An automatic emission device for corrosive gases from a single pile includes an exhaust system. The exhaust system includes an inlet pipe and an exhaust pipe, which are detachably connected to an opening at the top of the single pile body. The distance between the inlet pipe and the exhaust pipe is adjustable. The air inlet of the inlet pipe and the air outlet of the exhaust pipe are arranged opposite each other, and the size of their openings is adjustable. The air outlet of the inlet pipe and the air inlet of the exhaust pipe are located inside the single pile body and face downwards.

[0005] Based on the above technical solutions, the present invention may also employ the following further technical solutions, or combine these further technical solutions: The air outlet pipe has the same structure as the air inlet pipe. The air inlet pipe includes a first pipe and a second pipe, and the first pipe is retractably connected to the second pipe.

[0006] The first pipe is provided with a limiting block, and the second pipe is provided with a limiting groove. The limiting block is slidably connected to the limiting groove, so that the first pipe can slide and extend within the second pipe.

[0007] The air inlet of the air intake pipe and the air outlet of the air outlet pipe are respectively equipped with an air hole diameter adjustment device. The air hole diameter adjustment device includes a fixed plate, a sliding shaft, a rotating flap, and a lever. The fixed plate is provided with a sliding groove. The lower end of the sliding shaft is fixed on the rotating flap, and the upper end of the sliding shaft is slidably connected in the sliding groove. By pushing the lever, the fixed plate is rotated, thereby causing the sliding shaft to slide in the sliding groove, which in turn causes the rotating flap to open and close, thereby adjusting the size of the air hole.

[0008] The air outlet of the air inlet pipe and the air inlet of the air outlet pipe are respectively provided with fan assemblies, and the fan assembly includes a fan and a motor that drives the fan.

[0009] The automatic emission device for corrosive gases from a single pile also includes a gas concentration monitoring and exhaust control system. The gas concentration monitoring and exhaust control system is fixed to the inner wall at the middle position of the single pile body. The gas concentration monitoring and exhaust control system includes a motor controller, a sampling port, and a concentration detection sensor. The sampling port collects the gas inside the single pile body and transmits it to the concentration detection sensor. The concentration detection sensor is preset with a concentration threshold. When the gas inside the single pile body exceeds the concentration threshold, the concentration detection sensor sends a start signal to the motor controller. The motor controller controls the motors of the fan assembly in the air inlet pipe and the fan assembly in the air outlet pipe to start synchronously.

[0010] The automatic emission device for corrosive gases from a single pile also includes a flow velocity monitoring system, which is fixed to the inner wall at the middle of the single pile body.

[0011] The pore size can be adjusted from 0.6m to 0.3m.

[0012] Compared with the prior art, the present invention has the following advantages and beneficial effects: the exhaust system can be applied to monopile foundations of different sizes, and the best exhaust effect can be achieved by finely adjusting the distance between the intake pipe and the exhaust pipe, as well as the opening size of the air inlet of the intake pipe and the air outlet of the exhaust pipe.

[0018] To enable those skilled in the art to better understand the technical solutions of the present invention, preferred embodiments of the present invention are described below in conjunction with specific examples. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote elements with the same or similar functions throughout. However, it should be understood that the drawings are for illustrative purposes only and should not be construed as limiting the present invention. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product size. It is understandable for those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting the present invention.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0020] The present invention provides an automatic emission device for corrosive gases from a single pile, comprising an exhaust system 1. The exhaust system 1 includes an inlet pipe and an exhaust pipe, which are detachably connected to the upper opening of the single pile body 4. The distance between the inlet pipe and the exhaust pipe is adjustable. The air inlet of the inlet pipe and the air outlet of the exhaust pipe are arranged opposite to each other and the opening size of the two is adjustable. The air outlet of the inlet pipe and the air inlet of the exhaust pipe are inside the single pile body 4 and are arranged downwards.

[0021] like Figure 1 As shown, in this embodiment, the intake pipe and exhaust pipe of the exhaust system 1 are two L-shaped structures that are symmetrically distributed about the center of the single pile body 4.

[0022] The bottom of the single pile body 4, located below sea level 6, accumulates silt 7. Microorganisms in the silt 7 decompose and produce corrosive gases. The exhaust system 1 of this embodiment can introduce external air into the single pile body 4 and exhaust the corrosive gases inside the single pile body 4 to the outside.

[0023] The exhaust pipe and the intake pipe have the same structure. The intake pipe includes a first pipe 12 and a second pipe 13. The first pipe 12 is retractably connected to the second pipe 13.

[0024] The first pipe 12 is equipped with a limiting block 121, and the second pipe 13 is equipped with a limiting groove 131. The limiting block 121 is slidably connected to the limiting groove 131, allowing the first pipe 12 to slide and extend within the second pipe 13, thereby adjusting the interval between the intake and exhaust pipes. Numerical simulation studies show that the interval between the intake and exhaust pipes has a significant impact on the exhaust effect. With a single pile diameter of 8m and a pile length of 20m, when the interval between the intake and exhaust pipes is 4m and 5m, the gas flows directly from the intake pipe into the pile to the exhaust pipe, and the gas at the bottom of the pile cannot be discharged upwards. When the interval between the intake and exhaust pipes is 6m, it ensures that the gas can circulate in all positions within the pile, and the gas at the bottom of the pile can be discharged upwards. Therefore, in practical engineering, the appropriate interval between the intake and exhaust pipes can be adjusted according to the actual dimensions of the single pile to ensure that the introduced air can circulate in all positions within the pile, and that the gas at the bottom of the pile can be discharged upwards, ensuring a good exhaust effect.

[0025] The air inlet of the air intake pipe and the air outlet of the air outlet pipe are respectively equipped with an air hole diameter adjustment device 14. The air hole diameter adjustment device 14 includes a fixed plate 141, a sliding shaft 142, a rotating flap 143, and a lever 145. The fixed plate 141 is provided with a sliding groove 146. The lower end of the sliding shaft 142 is fixed on the rotating flap 143, and the upper end of the sliding shaft 142 is slidably connected in the sliding groove 146. By pushing the lever 145, the fixed plate 141 is rotated, thereby causing the sliding shaft 142 to slide in the sliding groove 146, thereby causing the rotating flap 143 to open and close, thereby adjusting the size of the air hole 144.

[0026] The gas aperture adjustment device 14 in this embodiment can be designed with reference to common knowledge of camera aperture adjustment structures.

[0027] The orifice diameter of vent 144 is adjustable from 0.6m to 0.3m. Numerical simulation studies show that the orifice diameter has a significant impact on the exhaust effect. With a single pile diameter of 8m and a pile length of 20m, if the pipe diameter is too small, the air introduced from the inlet pipe can only circulate in the upper part of the pile, and the gas at the bottom of the pile cannot be discharged upwards. If the pipe diameter is too large, the gas velocity will decrease when the same flow rate of air is introduced, reducing the exhaust efficiency. A pipe diameter of 0.4m ensures that the gas can circulate in all positions within the pile with the maximum velocity, resulting in the best exhaust effect. In practical engineering, the orifice diameter can be adjusted to a suitable size according to the actual dimensions of the single pile. While ensuring that the gas can circulate in all positions within the pile and that the gas at the bottom of the pile can be discharged upwards, a smaller orifice diameter can be selected to obtain a higher flow velocity, thus ensuring good exhaust performance. The movement of the gas at the bottom of the pile can be monitored by the flow velocity monitoring system 3.

[0028] The air inlet of the air inlet pipe and the air inlet of the air outlet pipe are respectively provided with fan assemblies 11, and the fan assembly 11 includes a fan and a motor that drives the fan.

[0029] The automatic emission device for corrosive gases in a single pile also includes a gas concentration monitoring and exhaust control system 2. The gas concentration monitoring and exhaust control system 2 is fixed to the inner wall of the middle part of the single pile body 4. The gas concentration monitoring and exhaust control system 2 includes a motor controller 21, a sampling port 23, and a concentration detection sensor 24. The sampling port 23 collects the gas inside the single pile body 4 and transmits it to the concentration detection sensor 24. The concentration detection sensor 24 is preset with a concentration threshold. When the gas inside the single pile body 4 exceeds the concentration threshold, the concentration detection sensor 24 sends a start signal to the motor controller 21. The motor controller 21 controls the motors of the fan assembly 11 in the air inlet pipe and the fan assembly 11 in the air outlet pipe to start synchronously.

[0030] The gas concentration monitoring and exhaust control system 2 also includes a protective shell 22. The gas concentration monitoring and exhaust control system 2 is fixed to the inner wall of the middle part of the single pile body 4 through the protective shell 22. The gas collected by the sampling port 23 enters the cavity inside the protective shell 22 and thus reaches the concentration detection sensor 24.

[0031] When the gas concentration inside the single pile body 4 is lower than the preset concentration threshold, the concentration detection sensor 24 sends a shutdown signal to the motor controller 21. The motor controller 21 controls the motors of the fan assembly 11 in the air intake pipe and the fan assembly 11 in the air outlet pipe to shut down synchronously, and the exhaust system stops operating.

[0032] This embodiment enables automatic start and stop of the exhaust system, avoiding the problem of excessive energy consumption caused by prolonged operation of the exhaust system.

[0033] During the operation of the exhaust system 1, the fans at the air outlet of the intake pipe and the air inlet of the exhaust pipe rotate in opposite directions to ensure that outside air enters through the intake pipe and corrosive gases are discharged through the exhaust pipe.

[0034] The automatic emission device for corrosive gases from a single pile also includes a flow velocity monitoring system 3, which is fixed to the inner wall at the middle position of the single pile body 4.

[0035] The gas velocity monitoring system utilizes the principle of electromagnetic induction to monitor the gas velocity inside a monopile. When gas flows through the system, it causes a coil within the system to rotate, resulting in a change in the magnetic flux within the coil and generating an induced electromotive force (EMF). The magnitude of this induced EMF is determined by the rate of change of the magnetic flux, which in turn is determined by the rotational speed of the coil, which in turn is determined by the velocity of the gas flowing through it. Therefore, the gas velocity can be determined by the magnitude of the induced EMF generated within the system as the gas flows through it. By detecting the gas velocity at different locations within the device, the exhaust efficiency of the system can be verified.

[0036] In this embodiment, the flow velocity monitoring system 3 uses the principle of electromagnetic induction to monitor the gas flow velocity inside the pile body 4 of a single pile, which facilitates the verification of the exhaust effect.
