Description

Technical Field

[0001] This utility model relates to the field of offshore wind turbine foundation construction, and in particular to an easy-to-install offshore wind turbine safety monitoring device. Background Technology

[0002] Offshore wind energy, as an important source of clean energy, continues to expand in scale. However, the complex and changeable marine environment, with extreme conditions such as strong winds and salt spray corrosion, poses severe challenges to the safety monitoring equipment of wind turbines.

[0003] Traditional monitoring equipment often uses ground-supported pillar structures, which suffers from complex installation and insufficient wind resistance. It is particularly susceptible to damage or detachment in strong winds, leading to data interruption and even safety accidents. Therefore, designing a safety monitoring device that is easy to install and has strong wind protection capabilities has become a pressing technical challenge in the offshore wind power sector. Utility Model Content

[0004] This utility model discloses an easy-to-install safety monitoring device for offshore wind turbines, aiming to solve the technical problem of how to design a safety monitoring device that is easy to install and has strong wind protection capabilities.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An easy-to-install offshore wind turbine safety monitoring device includes a lifting mechanism, and further includes: a top cover mechanism fixedly connected to the top of the lifting mechanism; a safety monitoring system and a wind force sensor, which are also installed on the lifting mechanism; and a drainage mechanism connected to the lifting mechanism.

[0007] The lifting mechanism includes: multiple square sleeves arranged in a multi-layered, interlocking configuration; an embedding chamber, with the lowest square sleeve fixedly connected to the inner wall of the bottom end of the embedding chamber; a square mounting column, movably interlocked to the inner wall of the innermost square sleeve, with the safety monitoring system and wind sensor simultaneously mounted on the square mounting column; and multiple hydraulic rods fixedly connected to the inner wall of the bottom end of the embedding chamber, with their output ends fixedly connected to the outer wall of the bottom end of the square mounting column.

[0008] Multiple square brackets have through slots on the same side of their inner walls. A connecting column is fixedly connected to the top outer wall of the square mounting column, and a top covering mechanism is fixed to the top of the connecting column.

[0009] Equipped with a lifting mechanism, when the wind sensor detects excessive wind force, the square mounting column and square sleeve are retracted into the embedded chamber by retracting the output end of the multi-section hydraulic rod. This prevents the safety monitoring system from being damaged or falling off in strong winds. Since the embedded chamber is installed underground, installation only requires digging a pit, inserting the embedded chamber, and fixing it with flanges and bolts. This ensures stability in high wind environments while greatly reducing the difficulty of installation.

[0010] In a preferred embodiment, the top covering mechanism includes: a top cover, with the top end of the connecting column fixedly connected to the bottom outer wall of the top cover; and an annular pressure plate disposed inside the top cover.

[0011] The top cover mechanism further includes: multiple springs, which are equidistantly fixed to the inner wall of the top of the annular pressure plate, and the tops of the multiple springs are simultaneously fixed to the inner wall of the top cover; and a sealing gasket, which is fixedly attached to the outer wall of the bottom of the annular pressure plate.

[0012] With a top cover mechanism, multiple springs compress simultaneously as the device descends. The combination of multiple springs and sealing gaskets optimizes the sealing performance between the annular pressure plate and the ground, preventing debris and excessive rainwater from entering the embedding chamber and affecting the device's operation, especially in windy and rainy conditions.

[0013] In a preferred embodiment, the top covering mechanism further includes: a groove 1, disposed on the inner wall of the top end of the top cover; a bracket 2, fixedly installed on the inner wall of the bottom end of the groove 1; and a cap, movably inserted into the groove 1, wherein the cap and the top cover form a complete hemisphere.

[0014] The top covering mechanism further includes: a sealing ring, which is fixedly attached to the outer circumference of the cap; and a bracket, which is fixedly connected to the outer top wall of the cap.

[0015] With the top cover mechanism, the second hanging bracket can be used to lift the lifting mechanism by attaching an external crane or other equipment to the second hanging bracket when the lifting mechanism malfunctions, facilitating maintenance. The cap and sealing ring provide protection for the second hanging bracket, ensuring it can withstand force. In addition, the hemispherical shape of the top of the top cover mechanism greatly reduces wind resistance and prevents the equipment from swaying due to strong winds.

[0016] In a preferred embodiment, the drainage mechanism includes: a sleeve, fixedly connected to the inner wall of one side of the embedded chamber; and a liquid-drawing hose, movably inserted into the sleeve, with its output end fixedly connected to an external water pump.

[0017] The drainage mechanism further includes: a second groove, which is located on the inner wall of the top of the embedded chamber, and the other end of the liquid extraction hose passes through the second groove; and a limiting sleeve, which is fixedly connected to the outer wall of one side of the embedded chamber and is movably sleeved outside the liquid extraction hose.

[0018] With a drainage mechanism, in rainy weather, multiple devices' pumping hoses can be connected to an external water pump to pump water out, preventing water accumulation that could cause corrosion and damage to multiple hydraulic rods.

[0019] As described above, an easy-to-install offshore wind turbine safety monitoring device includes a lifting mechanism, and further includes: a top covering mechanism fixedly connected to the top of the lifting mechanism; a safety monitoring system and a wind power sensor, both installed on the lifting mechanism; and a drainage mechanism connected to the lifting mechanism. The lifting mechanism includes: multiple square sleeves arranged in a multi-layered, interlocking configuration; an embedded chamber, with the lowest square sleeve fixedly connected to the inner wall of the bottom end of the embedded chamber; a square mounting column, movably interlocked with the inner wall of the innermost square sleeve, with the safety monitoring system and wind power sensor both installed on the square mounting column; and multiple hydraulic rods fixedly connected to the inner wall of the bottom end of the embedded chamber, with their output ends fixedly connected to the outer wall of the bottom end of the square mounting column. This utility model provides an easy-to-install offshore wind turbine safety monitoring device that, while ensuring stability in high-wind environments, also significantly reduces installation difficulty.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] The present invention discloses an easy-to-install offshore wind turbine safety monitoring device, which is mainly used in offshore wind turbine safety monitoring scenarios.

[0027] Reference Figure 1 and Figure 2 An easy-to-install offshore wind turbine safety monitoring device includes a lifting mechanism 2, and further includes: a top cover mechanism 1 fixedly connected to the top of the lifting mechanism 2; a safety monitoring system 3 and a wind force sensor 4, which are installed on the lifting mechanism 2; and a drainage mechanism 5 connected to the lifting mechanism 2.

[0028] The lifting mechanism 2 includes: multiple square sleeves 206 arranged in a multi-layered, interlocking configuration; an embedded compartment 205, with the lowest square sleeve 206 fixedly connected to the inner wall of the bottom end of the embedded compartment 205; a square mounting column 202, movably interlocked with the inner wall of the innermost square sleeve 206, and the safety monitoring system 3 and the wind sensor 4 are simultaneously mounted on the square mounting column 202; and a multi-section hydraulic rod 204, fixedly connected to the inner wall of the bottom end of the embedded compartment 205, with its output end fixedly connected to the outer wall of the bottom end of the square mounting column 202. During daily use, the wind sensor 4 can monitor the sea wind force in real time. If the wind is too strong, the square mounting column 202 and the square sleeve 206 can be retracted into the embedded chamber 205 by retracting the output end of the multi-section hydraulic rod 204, thereby preventing the safety monitoring system 3 from being damaged or falling off in strong winds. At the same time, since the embedded chamber 205 is installed underground, compared with the existing support columns of the monitoring equipment, which require welding or bolting the reinforcing bars one by one to provide stability, this solution only requires digging a pit, inserting the embedded chamber 205 and fixing it with flanges and bolts. While ensuring stability in strong winds, it also greatly reduces the installation difficulty.

[0029] Reference Figure 2 In a preferred embodiment, the inner walls of multiple square brackets 206 on the same side are simultaneously provided with through slots 203, the top outer wall of the square mounting column 202 is fixedly connected to a connecting column 201, and the top covering mechanism 1 is fixed to the top of the connecting column 201. The through slots 203 can ensure that the safety monitoring system 3 and the wind sensor 4 are not obstructed during the lifting process.

[0030] Reference Figure 4 In a preferred embodiment, the drainage mechanism 5 includes: a sleeve 504, which is fixedly connected to the inner wall of one side of the embedded chamber 205; and a liquid extraction hose 501, which is movably inserted into the sleeve 504, and whose output end is fixedly connected to an external water pump.

[0031] Reference Figure 4 In a preferred embodiment, the drainage mechanism 5 further includes: a second groove 503, which is disposed on the inner wall of the top of the embedded chamber 205, and the other end of the suction hose 501 passes through the second groove 503; a limiting sleeve 502, which is fixedly connected to the outer wall of one side of the embedded chamber 205, and is movably sleeved outside the suction hose 501. In rainy weather, the suction hoses 501 of multiple devices can be connected simultaneously by an external water pump to pump water outward. Since the bottom end of the suction hose 501 is close to the bottom end of the embedded chamber 205, the water remaining in the embedded chamber 205 can be directly pumped out, avoiding water accumulation that could cause corrosion and damage to the multi-section hydraulic rod 204, thus ensuring its service life. The setting of the second groove 503 can provide space for the installation of the suction hose 501, avoiding affecting the downward sealing of the top covering mechanism 1.

[0032] Reference Figure 3 In a preferred embodiment, the top covering mechanism 1 includes: a top cover 105, the top end of the connecting column 201 being fixedly connected to the bottom outer wall of the top cover 105; and an annular pressure plate 108 disposed inside the top cover 105.

[0033] Reference Figure 3 In a preferred embodiment, the top covering mechanism 1 further includes: a plurality of springs 107, which are equidistantly fixed to the inner wall of the top of the annular pressure plate 108, and the tops of the plurality of springs 107 are simultaneously fixed to the inner wall of the top cover 105; and a sealing gasket 109, which is fixedly attached to the outer wall of the bottom end of the annular pressure plate 108. After the lifting mechanism 2 descends to the bottom, the annular pressure plate 108 contacts the ground. As it continues to descend, the plurality of springs 107 are compressed simultaneously, and the plurality of springs 107 provide extrusion force. At the same time, based on the setting of the sealing gasket 109, the extrusion sealing between the annular pressure plate 108 and the ground can be optimized, and it can be prevented that garbage and too much rainwater will enter the embedded chamber 205 in windy and rainy environments, thus affecting the use of the equipment.

[0034] Reference Figure 3 In a preferred embodiment, the top covering mechanism 1 further includes: a groove 104 disposed on the inner wall of the top end of the top cover 105; a bracket 106 fixedly installed on the inner wall of the bottom end of the groove 104; and a cap 102 movably inserted into the groove 104, wherein the cap 102 and the top cover 105 form a complete hemisphere.

[0035] Reference Figure 3In a preferred embodiment, the top covering mechanism 1 further includes: a sealing ring 103, which is fixedly attached to the outer circumferential wall of the cap 102; a first bracket 101, which is fixedly connected to the top outer wall of the cap 102. The second bracket 106 is provided so that when the lifting mechanism 2 malfunctions, it can be lifted by attaching it to the second bracket 106 with an external crane or other equipment, which facilitates maintenance. The cap 102 and the sealing ring 103 can be used to seal and snap into the first groove 104, preventing rainwater from entering and causing rust and corrosion at the connection of the second bracket 106, which would affect its load-bearing capacity. In addition, since the top of the top covering mechanism 1 is hemispherical, wind resistance can be reduced to a large extent, preventing the equipment from shaking due to strong winds.

[0036] Working principle: During daily use, the wind sensor 4 can monitor the sea wind force in real time. If the wind force is too strong, the square mounting column 202 and the square sleeve 206 are retracted into the embedding chamber 205 by the retraction of the output end of the multi-section hydraulic rod 204, thereby preventing the safety monitoring system 3 from being damaged or falling off in strong winds. At the same time, since the embedding chamber 205 is installed underground, compared with the existing support columns of the monitoring equipment, which require welding or bolting of the reinforcing bars one by one to provide stability, this solution only requires digging a pit, inserting the embedding chamber 205 and fixing it with flanges and bolts. While ensuring stability in strong wind environments, it also greatly reduces the installation difficulty.

[0037] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
