Description

Technical Field

[0001] The present invention relates to the field of offshore wind measurement devices, and particularly to an offshore floating lidar wind measurement device. Background Art

[0002] In case of strong winds and waves or extreme weather, the offshore floating platform will shake violently. Since the existing equipment usually uses bolt connection or directly welds the radar to the mounting bracket for fixation, the long-term shaking will not only loosen the connection parts, affecting the installation stability of the radar, but also the seawater usually splashes onto the radar, bolt connection or welding part. After being eroded by seawater for a long time, the radar, bolt connection or welding part will gradually be corroded. To avoid affecting the normal use of the radar, manual maintenance needs to be carried out frequently, which not only has a high maintenance cost, but also has many inconveniences during the maintenance process as the floating platform is located in the sea area.

[0003] As a key part for signal transmission, the radar window is exposed to a humid and high-salt environment for a long time and is severely eroded. Moreover, in order not to interfere with the laser transmission effect of the lidar window, generally, a thick protective layer is not coated on the lidar window to reduce the possibility of optical distortion under extreme humidity. However, reducing the thickness of the protective layer means that its maintenance frequency needs to be increased, and manual maintenance at sea is required, which is not convenient enough. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following advantages: The present invention realizes buffering and filtering the shaking of the foundation through the spring inside the airbag, thereby greatly reducing the shaking transmitted to the radar, and further ensuring that the radar can work in a relatively stable state. At the same time, when the wind and waves are large, the sea water will directly slap on the outer buffer cover and the airbag, thereby improving the protection effect on the radar. Compared with directly welding the radar on the mounting bracket, the present invention directly limits and fixes the radar through the spring inside the airbag, ensuring that the radar performs detection under relatively stable conditions, so that there is no need for manual maintenance of the radar on the floating platform frequently, reducing its maintenance cost; Through the frequent contraction and expansion of the airbag, the outside air enters the inside of the airbag through the air pipe, and finally discharges to the outside through the heat dissipation holes of the buffer cover, thereby improving the air flow rate in the chamber formed by the buffer cover and the airbag, and thus enhancing the heat dissipation effect of the radar; By setting the clamping ring and the screw rod as independent individuals, without affecting the installation stability of the radar, even if the clamping ring and the screw rod are corroded by sea water, the staff can still carry out rapid disassembly and assembly, which not only reduces the complexity and difficulty of installation, improves the use convenience of the device, but also greatly improves the disassembly and assembly efficiency of the staff; Through the shaking of the floating platform, the airbag contracts and expands frequently, driving the cleaning block to clean the impurities adhered to the window glass of the radar. At the same time, the cleaning agent can form an extremely thin protective film on the surface of the window glass to reduce the adhesion of sea water, thereby ensuring the subsequent detection accuracy of the radar.

[0019] Embodiment 1 As Figures 1 - 7 shown, an offshore floating lidar anemometer includes a floating platform 1, a mounting bracket 2, a fixing plate and a radar 6; the floating platform 1 is provided with a mounting bracket 2; two symmetrically arranged fixing plates are mounted on the mounting bracket 2; a radar 6 is placed on the mounting bracket 2; a window glass 6001 is arranged on the front side of the radar 6; It further includes a buffer cover 3, an airbag 4 and a ventilation pipe 5; the buffer cover 3 is arranged on the mounting bracket 2; a front plate 3001 is fixedly connected to the front side of the buffer cover 3; the rear side of the buffer cover 3 is detachably connected with a rear plate 3002; a light-transmitting hole is formed in the front plate 3001; a plurality of heat dissipation holes 3003 are arranged on the rear plate 3002; an airbag 4 is installed on each fixing plate, and the airbags 4 are evenly distributed on the left and right sides of the radar 6; a plurality of elastic members are fixedly connected in each airbag 4, and the elastic members are springs; four exhaust holes are arranged on one side of each airbag 4 close to the radar 6, and a one-way diaphragm 4001 is installed in each exhaust hole; the airbag 4 is communicated with the ventilation pipe 5; a one-way valve opening towards the inside of the airbag 4 is arranged at the pipe orifice of each ventilation pipe 5.

[0020] A protective cover 3004 is arranged on the rear plate 3002, and the protective cover 3004 is located above the heat dissipation holes 3003.

[0021] Both the buffer cover 3 and the airbag 4 are made of corrosion-resistant materials.

[0022] The pipe orifice of each ventilation pipe 5 faces downward.

[0023] The working process of this embodiment is as follows: When the sea floating platform 1 shakes violently in strong winds and waves or in extreme weather, since the existing equipment usually uses bolt connection or directly welds the radar 6 to the mounting bracket 2 for fixation, the long-term shaking will not only cause the connection parts to become loose, affecting the installation stability of the radar 6, but also seawater usually splashes onto the radar 6, bolt connection parts or welding parts. After being eroded by seawater for a long time, the radar 6, bolt connection parts or welding parts will all be gradually corroded. To avoid affecting the normal use of the radar 6, manual maintenance is required frequently, but the floating platform 1 is located in the sea area, and there are many inconveniences during the maintenance process.

[0024] To solve the above problems, during the installation process, first remove the rear plate 3002 of the buffer cover 3, then place the radar 6 into the buffer cover 3, and align and fit the viewing window glass 6001 of the radar 6 with the light-transmitting hole of the front plate 3001, so that the radar 6 can emit laser beams through the light-transmitting hole for detection. At the same time, the buffer cover 3 shields and protects the upper and lower side surfaces and the front side surface of the radar 6. Then, the airbag 4 shields and protects the left and right side surfaces of the radar 6, that is, the radar 6 is located inside the chamber formed by the buffer cover 3 and the airbag 4 at this time. It should be noted that both the buffer cover 3 and the airbag 4 are closely attached to the radar 6. Since several springs are provided in each airbag 4, the airbags 4 on the left and right sides will clamp and fix the radar 6. Then, snap the rear plate 3002 back onto the buffer cover 3. Since one side of the airbag 4 is directly connected to the floating platform 1 through the fixing plate, and the other side is in extrusion fit with the radar 6, when the floating platform 1 shakes, the springs inside the airbag 4 buffer and filter the foundation's shaking, so that the shaking transmitted to the radar 6 is greatly reduced, and the radar 6 moves slightly inside the chamber formed by the buffer cover 3 and the airbag 4, thereby ensuring that the radar 6 can work in a relatively stable state. It should be noted that in the initial state, the springs inside the airbag 4 are in a compressed state due to the extrusion of the radar 6. At the same time, when the wind and waves are large, the sea water will directly hit the outer buffer cover 3 and the airbag 4, thereby improving the protection effect on the radar 6. Compared with directly welding the radar 6 to the mounting bracket 2, the present invention directly limits and fixes the radar 6 through the springs inside the airbag 4, ensuring that the radar 6 performs detection under relatively stable conditions, so that there is no need for manual frequent maintenance of the radar 6 on the floating platform 1, reducing its maintenance cost.

[0025] After the radar 6 conducts long-term detection, the inside of the radar 6 will gradually heat up, and the dissipated heat will be discharged outward through the heat dissipation holes 3003 of the buffer cover 3. To further improve the heat dissipation effect of the radar 6, during the process of the floating platform 1 shaking due to being slapped by the sea waves, the floating platform 1 will drive the mounting bracket 2 and the airbag 4 to tilt to the left or right. Under the action of the springs inside the airbag 4 buffering and filtering the foundation's shaking, the radar 6 will move slightly to the left or right inside the chamber formed by the buffer cover 3 and the airbag 4. At the same time, taking the leftward movement as an example, the radar 6 will gradually approach the left airbag 4 and move away from the right airbag 4. At this time, the left airbag 4 will be secondarily extruded by the radar 6, with its volume decreasing, while the right airbag 4 will increase in volume due to the spring rebound inside. Vice versa, so the volume of the airbag 4 will constantly change. When the volume inside the airbag 4 decreases, the gas inside the airbag 4 will impact the one-way diaphragm 4001 through the exhaust hole, as Figure 7As shown, the one-way diaphragm 4001 is opened towards the radar 6 side, so that gas enters the chamber formed by the buffer cover 3 and the airbag 4, and finally is discharged to the outside through the heat dissipation holes 3003 of the buffer cover 3. Thereby, the flow rate of the gas in the chamber formed by the buffer cover 3 and the airbag 4 is increased, so as to enhance the heat dissipation effect of the radar 6, and to ensure the normal working environment required by the radar 6 to the greatest extent. At the same time, the heat dissipation holes 3003 of the buffer cover 3 are masked by the protective cover 3004, so as to effectively prevent seawater from entering the inside of the buffer cover 3 through the heat dissipation holes 3003 and avoid corrosion of the radar 6. On the contrary, when the internal volume of the airbag 4 increases, a negative pressure is formed, and then the one-way valve of the ventilation pipe 5 is opened towards the inside of the airbag 4, and the outside gas is supplemented into the airbag 4. Until the airbag 4 is squeezed again, the gas inside the airbag 4 will enter the chamber formed by the buffer cover 3 and the airbag 4 through the one-way diaphragm 4001. Thereby, the flow of the gas in the chamber and the outside gas is accelerated. At the same time, by arranging the pipe orifice of the ventilation pipe 5 downward, seawater is prevented from entering the inside of the airbag 4 through the ventilation pipe 5, causing corrosion inside the airbag 4, and improving the protection performance of the device.

[0026] Embodiment 2 On the basis of Embodiment 1, as Figures 1 - 3 and Figures 8 - 12 shown, it further includes a clamping ring 103, a screw rod 104 and a limiting rod 105; each fixing plate is composed of a fixing block 101 and a clamping block 102; two symmetrically arranged fixing blocks 101 are fixedly connected to the mounting bracket 2; a rotating shaft 10101 is arranged on each fixing block 101; a clamping block 102 is rotatably connected to each rotating shaft 10101; a clamping ring 103 is clamped between the upper and lower adjacent fixing blocks 101 and clamping blocks 102; a screw rod 104 is rotatably connected to each clamping ring 103; a limiting rod 105 is slidably connected to the mounting bracket 2, and the limiting rod 105 penetrates through the adjacent clamping block 102, so as to realize the limitation of the clamping block 102; two symmetrically arranged connecting parts 4002 are arranged on one side of each airbag 4 close to the clamping block 102, and each screw rod 104 is rotatably connected to one side of the airbag 4 close to the fixing block 101 through the connecting part 4002; each airbag 4 is slidably connected to the mounting bracket 2; two symmetrically arranged grooves are arranged on each fixing block 101 and clamping block 102; one side of each airbag 4 close to the fixing plate is made of a hard material.

[0027] Each clamping ring 103 is provided with a concave part 10301.

[0028] It also includes a liquid storage box 201, a pressing block 202 and a cleaning block 203; the liquid storage box 201 is detachably connected to the front side of the radar 6; on one side of each airbag 4 away from the buffer cover 3, a pressing block 202 is fixedly connected through a round rod, and each pressing block 202 penetrates through the front plate 3001; both the left side and the right side of the front plate 3001 are set as telescopic structures; a light-transmitting tube 3005 is installed on the light-transmitting hole of the front plate 3001; a cleaning block 203 is installed on the light-transmitting tube 3005, and the cleaning block 203 is communicated with the liquid storage box 201 through a communicating pipe; the cleaning block 203 is made of a water-absorbing material.

[0029] A pressure film is arranged at the communicating part of the communicating pipe and the liquid storage box 201.

[0030] The cleaning block 203 is set as an annular structure.

[0031] It also includes a heat-conducting tube 204; the light-transmitting tube 3005 is made of a heat-conducting material; an external heating device is arranged inside the mounting bracket 2; the heat-conducting tube 204 is fixedly connected to the lower side of the light-transmitting tube 3005, and the heat-conducting tube 204 is connected to the external heating device.

[0032] The working steps of this embodiment are as follows: When the existing lidar wind measurement device is installed, corresponding bolt holes are preset on its base and the mounting bracket 2, and then the two are tightly connected using high-strength bolts. This method is indeed relatively convenient during the installation process. However, since the lidar wind measurement device is located at sea, during the shaking of the floating platform 1, the waves slapped up will corrode the connection part of the bolts, resulting in rust on the surface of the bolts. This will not only increase the friction between the threads but also reduce the strength of the bolts, causing the bolts to break during subsequent disassembly, thus increasing the difficulty of disassembly and bringing great difficulties to the disassembly work.

[0033] To solve the above problems, after the radar 6 is placed inside the chamber formed by the buffer cover 3 and the airbag 4, taking the right-hand catch 102 as an example, at this time, manually pull out the limit rod 105 to the right to release the restriction on the catch 102, then lift the catch 102 upward so that the catch 102 rotates upward around the rotating shaft 10101, and then place the two snap rings 103 at the front and rear grooves on the fixed block 101 respectively. Then rotate the catch 102 downward to make the catch 102 return to its initial position, and push the limit rod 105 to the left to limit the catch 102 again, as Figure 10As shown, screw rod 104 is screwed into the adjacent clamping ring 103. At the same time, the friction between the clamping ring 103 and the fixing block 101 and the clamping block 102 is increased through the concave part 10301, thereby improving the stability of the clamping ring 103 in the fixing block 101 and the clamping block 102, and enabling the end of the screw rod 104 to be clamped with the adjacent connecting part 4002. Then, according to the installation requirements, the screwing distance of the screw rod 104 is controlled. As the screw rod 104 rotates, the end of the screw rod 104 will gradually squeeze the airbag 4, thereby adjusting the fitting distance between the airbag 4 and the radar 6, changing the deformation degree of the spring inside the airbag 4 to adapt to the actual shaking situation, ensuring more appropriate protection for the radar 6 under different conditions. At the same time, when problems such as damage and aging occur to the airbag 4 after long-term use, the airbag 4 can be directly disassembled from the mounting bracket 2, so that maintenance personnel can check, repair or replace it, thus eliminating the need for large-scale disassembly of the entire wind measurement device, reducing maintenance time and costs, and improving the usability of the device. When subsequent staff repairs the equipment, if the connection part between the clamping ring 103 and the screw rod 104 becomes rusty and is difficult to disassemble, at this time, the limiting rod 105 is manually pulled out to the right to release the restriction on the clamping block 102, then the clamping block 102 is lifted upward, and then the clamping ring 103 and the screw rod 104 are taken off as a whole, and a new clamping ring 103 and screw rod 104 are replaced. Then, the staff only needs to repeat the above installation steps to complete the replacement. By setting the clamping ring 103 and the screw rod 104 as independent individuals, without affecting the installation stability of the radar 6, even if the clamping ring 103 and the screw rod 104 are corroded by seawater, the staff can still carry out quick disassembly and assembly, which not only reduces the complexity and difficulty of installation, improves the use convenience of the device, but also greatly improves the disassembly and assembly efficiency of the staff.

[0034] When the offshore floating lidar wind measurement device is strongly impacted by ocean waves, the seawater splashing will cause a large amount of seawater to adhere to the window glass 6001 on the front side of the lidar 6. After the seawater evaporates, minerals such as salts will be left behind, resulting in white salt stains on the window glass 6001, which weakens the signal intensity received by the receiving end of the lidar 6, thus affecting the detection accuracy of the lidar 6. To solve the above problems, when the wind measurement device is strongly impacted by ocean waves, during the violent shaking of the floating platform 1, the airbag 4 will be more strongly squeezed by the lidar 6. As the volume of the airbag 4 is gradually squeezed and contracted, the side of the airbag 4 away from the buffer cover 3 will gradually approach the lidar 6, driving the round rod fixedly connected to the extrusion block 202 and the extrusion block 202 to approach the liquid storage box 201, and squeezing the liquid storage box 201, so that the cleaning agent in the liquid storage box 201 is squeezed into the cleaning block 203 through the connecting pipe, wetting the cleaning block 203. At the same time, when the lidar 6 moves slightly to the left or right inside the chamber formed by the buffer cover 3 and the airbag 4, the front plate 3001 and the light-transmitting pipe 3005 of the buffer cover 3 will shake left and right relative to the lidar 6. Therefore, during the shaking of the mounting bracket 2, the mounting bracket 2 will drive the front plate 3001, the light-transmitting pipe 3005 and the cleaning block 203 to shake together, so that the cleaning block 203 wipes the window glass 6001 of the lidar 6, thereby cleaning the impurities adhering to the window glass 6001 of the lidar 6. At the same time, the cleaning agent can form an extremely thin protective film on the surface of the window glass 6001, reducing the adhesion of seawater, thereby reducing the impact of impurities on the detection accuracy of the lidar 6. At the same time, the floating platform 1 not only shakes simply from side to side, but also has irregular up and down undulating motions. By setting the cleaning block 203 as an annular structure to fit the shaking situation of the floating platform 1, the cleaning effect of the cleaning block 203 on the window glass 6001 can be improved. It should be noted that in the initial state, there is a gap between the extrusion block 202 and the liquid storage box 201. Therefore, only when the floating platform 1 is violently shaken can the extrusion block 202 squeeze the liquid storage box 201, which will not affect the normal use of the lidar 6. At the same time, by setting a pressure film at the connecting part of the connecting pipe connected to the cleaning block 203 and the liquid storage box 201, it can effectively prevent the cleaning agent in the liquid storage box 201 from flowing into the cleaning block 203 during the normal use of the lidar 6, causing waste of resources.

[0035] When freezing rain occurs at sea, when the raindrops come into contact with the anemometer whose temperature is below 0 degrees Celsius, they will quickly freeze and form a transparent or semi-transparent ice layer. In this case, the staff usually turns off the radar 6 and makes it idle. Although the periphery of the radar 6 is protected and wrapped by the buffer cover 3 and the airbag 4, ice will form inside the light-transmitting holes on the front panel 3001. Therefore, after the freezing rain weather ends, in order to quickly put the radar 6 into use, the external heating device in the mounting bracket 2 is started at this time, and the heat is conducted to the heat-conducting tube 204 and the light-transmitting tube 3005 to melt the ice layer, thereby improving the convenience of using the device. It should be noted that the driving energy for the use of the above external heating device and the radar 6 comes from the battery inside the floating platform 1 and the external solar panels for power supply.

[0036] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
