Description

Technical Field

[0001] This utility model relates to the field of wind power monitoring, specifically a nacelle radar that is easy to install. Background Technology

[0002] A nacelle radar is a device installed in the nacelle area of ​​a wind turbine generator set. It is used to detect the surrounding environment, target location, or equipment operating status using radar detection technology. By transmitting and receiving electromagnetic wave signals, it obtains information such as target distance, position, and movement based on signal changes. It can assist in safety monitoring, obstacle identification, and status judgment during wind turbine operation, reduce the difficulty of manual inspection, improve the information acquisition capability during unit operation, and provide data support for the safe operation and maintenance of wind turbine generator sets.

[0003] Existing nacelle radars typically use brackets and bolts for fixed installation. This not only makes installation and disassembly cumbersome, but also requires disassembling and reassembling multiple fasteners one by one during equipment inspection, replacement, or maintenance, affecting installation efficiency. Furthermore, under long-term vibration in the nacelle environment, traditional bolt connections are prone to loosening due to continuous vibration, reducing the stability and reliability of the radar installation. In addition, most existing installation structures lack support structures that facilitate adjustment of the radar's installation direction. When the monitoring direction changes, the adjustment process is complicated, and some support mechanisms lack effective protection measures for the transmission areas, allowing rainwater to easily enter the transmission parts and affect the transmission components, thereby reducing the stability and service life of the support mechanism. Based on this, this utility model designs an easily installable nacelle radar to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an easy-to-install cabin radar to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An easy-to-install nacelle radar includes a radar body with a tenon-and-mortise joint mechanism located below it. An adjustable support mechanism is located below the tenon-and-mortise joint mechanism. The tenon-and-mortise joint mechanism includes an insert plate, a insert post, a limiting insert post, a mounting pad, a first return spring, a first limiting protrusion, a second return spring, a second limiting protrusion, a fixing post, a mounting screw, and a limiting nut. The insert post is fixedly connected to the radar body. The limiting insert post is inserted into the insert plate and engages with the insert post for limiting. The fixing post is fixedly mounted on the adjustable support mechanism. The adjustable support mechanism supports and drives the tenon-and-mortise joint mechanism and the radar body to rotate.

[0006] Optionally, the mounting pad is fixedly installed on the inner wall of the limiting plug, the first return spring is fixedly installed on the upper end of the mounting pad, the first limiting protrusion is fixedly installed on the upper end of the first return spring, the second return spring is fixedly installed on the lower end of the mounting pad, and the second limiting protrusion is fixedly installed on the lower end of the second return spring. Both the first limiting protrusion and the second limiting protrusion are in a limiting relationship with the plug body.

[0007] Optionally, both the first limiting protrusion and the second limiting protrusion are dome structures, and an installation screw is fixedly installed at the rear end of the limiting insertion post, with a limiting nut provided on the outer side of the installation screw.

[0008] Optionally, the adjustable support mechanism includes a mounting plate, a drive motor, a drive gear, a bearing sleeve, a transmission shaft, a transmission gear, a rotating disk, a rain guard ring, and a protective cover. The drive motor and the bearing sleeve are both fixedly mounted on the upper end of the mounting plate.

[0009] Optionally, the output end of the drive motor is fixedly connected to a drive gear, the drive gear meshes with a transmission gear, a transmission shaft is fixedly installed in the middle of the transmission gear, the transmission shaft and the bearing sleeve are plugged into each other, a rotating disk is fixedly installed at the upper end of the transmission gear, and a fixed column is fixedly installed on the rotating disk.

[0010] Optionally, a rain shield ring is fixedly installed on the outer wall of the rotating disk, and a protective cover is provided below the rain shield ring, with the protective cover fixedly installed on the mounting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model is equipped with a tenon and mortise insertion mechanism, which forms a quick-connect installation structure through the insertion column, the insertion plate, and the limiting insertion column. Through the automatic reset action of the first return spring, the first limiting protrusion, the second return spring, and the second limiting protrusion, the limiting insertion column and the insertion column body are quickly limited and connected. This improves installation stability while ensuring installation efficiency. The installation screw and the limiting nut are used to fix the limiting insertion column again, preventing the limiting insertion column from accidentally coming out due to continuous vibration during long-term operation. This improves the installation reliability and safety of the radar body, makes assembly and disassembly more convenient, and the overall structure is simple, making it easy to process, manufacture, and install and maintain on site.

[0012] 2. In this utility model, an adjustable support mechanism is provided. Through the transmission cooperation of the drive motor, drive gear, transmission gear, transmission shaft and rotating disk, the angle of the radar body can be adjusted, so that the nacelle radar can be adjusted according to the actual installation requirements, thereby improving the monitoring coverage. At the same time, the rain shield ring and the protective cover form a shielding and protective structure, which can reduce the entry of rainwater into the support mechanism, protect the drive components, reduce the impact of the external environment on the transmission structure, and improve the stability and reliability of the whole device in complex environments.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-9 In this embodiment of the present invention, an easy-to-install cabin radar includes a radar body 1. A tenon-and-mortise joint mechanism 2 is provided below the radar body 1, and an adjustable support mechanism 3 is provided below the tenon-and-mortise joint mechanism 2. The tenon-and-mortise joint mechanism 2 includes an insertion plate 201, an insertion post 202, a limiting insertion post 203, a mounting pad 204, a first return spring 205, a first limiting protrusion 206, a second return spring 207, a second limiting protrusion 208, a fixing post 209, a mounting screw 210, and a limiting nut 211. The adjustable support mechanism 3 includes a mounting plate 301, a drive motor 302, a drive gear 303, a bearing sleeve 304, a transmission shaft 305, a transmission gear 306, a rotating disk 307, a rain shield ring 308, and a protective cover 309.

[0019] The radar body 1 has a fixedly installed insert 202 at its lower end, an insert plate 201 on the outer side of the insert 202, a limiting insert 203 inserted into the insert plate 201, a mounting pad 204 fixedly installed on the inner wall of the limiting insert 203, a first return spring 205 fixedly installed on the upper end of the mounting pad 204, a first limiting protrusion 206 fixedly installed on the upper end of the first return spring 205, a second return spring 207 fixedly installed on the lower end of the mounting pad 204, and a second limiting protrusion 208. Fixedly installed at the lower end of the second return spring 207, the first limiting protrusion 206 and the second limiting protrusion 208 are both in a limiting relationship with the insert body 202, and the first limiting protrusion 206 and the second limiting protrusion 208 are both dome structures. The rear end of the limiting insert 203 is fixedly installed with an installation screw 210, and a limiting nut 211 is provided on the outside of the installation screw 210. The fixing post 209 is fixedly installed on the rotating disk 307, so that the tenon and mortise insertion mechanism 2 can be installed above the adjustable support mechanism 3.

[0020] The upper end of the mounting plate 301 is fixedly mounted with a drive motor 302 and a bearing sleeve 304. The output end of the drive motor 302 is fixedly connected to a drive gear 303. A transmission gear 306 meshes with the front of the drive gear 303. A transmission shaft 305 is fixedly mounted in the middle of the transmission gear 306. The transmission shaft 305 and the bearing sleeve 304 are plugged into each other. A rotating disk 307 is fixedly mounted on the upper end of the transmission gear 306. A rain shield 308 is fixedly mounted on the outer wall of the rotating disk 307. A protective cover 309 is provided below the rain shield 308. The protective cover 309 is fixedly mounted on the mounting plate 301. The rain shield 308 is located outside the protective cover 309, forming a shield and protection for the transmission area of ​​the adjustable support mechanism 3.

[0021] In this embodiment, the mounting plate 301 is first fixedly installed in the mounting position of the cabin, so that the entire adjustable support mechanism 3 forms a stable support. Then, the insert 202 at the lower end of the radar body 1 is inserted into the insert plate 201 from top to bottom, and continues to pass downward through the mounting position corresponding to the rotating disk 307, so that the radar body 1 is initially positioned. The insert 202, as the main mounting body, plays a supporting role for the radar body 1. Then, the limiting insert 203 is inserted laterally along the insert plate 201. During the movement of the limiting insert 203, the mounting pad 204 drives the first return spring 205, the first limiting protrusion 206, the second return spring 207, and the second limiting protrusion 208 to move synchronously. When the first limiting protrusion 206 and the second limiting protrusion 208 contact the insert 202, the first return spring 205 and the second return spring 207 move synchronously. 7 are subjected to compression and elastic deformation, causing the first limiting protrusion 206 and the second limiting protrusion 208 to retract. When the limiting insert 203 continues to be inserted into the installation position, the first return spring 205 and the second return spring 207 respectively push the first limiting protrusion 206 and the second limiting protrusion 208 to return outward, so that the first limiting protrusion 206 and the second limiting protrusion 208 re-form a limiting engagement with the insert body 202, thereby completing the rapid installation of the radar body 1. The insertion engagement between the insert body 202 and the insert plate 201 forms the installation positioning, and the limiting insert 203 is used for lateral limiting, making the installation process simple and quick. At the same time, the elastic restoring action of the first return spring 205 and the second return spring 207 keeps the first limiting protrusion 206 and the second limiting protrusion 208 in a stable limiting state, improving the connection stability.

[0022] Furthermore, to improve installation reliability during long-term operation, after the limit plug 203 is installed, the limit plug 203 is re-fixed by the installation screw 210 in conjunction with the limit nut 211. This ensures that the limit plug 203 remains stable under long-term vibration, reducing the possibility of the limit plug 203 loosening or coming off due to continuous vibration. This further improves the installation reliability of the radar body 1 and facilitates subsequent disassembly and maintenance. When disassembly is required, only the limit nut 211 needs to be removed, and then the limit plug 203 needs to be pulled out to remove the entire radar body 1 without disassembling a large number of installation components, making equipment maintenance and replacement convenient.

[0023] When the monitoring direction of the radar body 1 needs to be adjusted, the drive motor 302 is started. The output end of the drive motor 302 drives the drive gear 303 to rotate. The drive gear 303 meshes and drives the transmission gear 306 to rotate. The transmission gear 306 drives the transmission shaft 305 to rotate stably in the bearing sleeve 304, and further drives the rotating disk 307 to rotate synchronously. Since the fixed column 209 is fixedly installed on the rotating disk 307, the fixed column 209 drives the tenon and mortise insertion mechanism 2 and the radar body 1 installed on it to rotate synchronously, realizing the adjustment of the installation direction of the radar body 1. This allows the radar body 1 to adjust the monitoring direction according to actual usage needs, improving the applicability of the equipment.

[0024] Furthermore, during the operation of the adjustable support mechanism 3, the rain shield ring 308 rotates synchronously with the rotating disk 307, and the protective cover 309 is fixedly installed on the mounting plate 301. The rain shield ring 308 is located on the outside of the protective cover 309. When rainwater falls into the rotating area, the rain shield ring 308 forms a shield and guides the rainwater, causing the rainwater to flow outward along the rain shield ring 308, reducing the possibility of rainwater entering the interior of the protective cover 309, and protecting the drive motor 302, drive gear 303, transmission gear 306, transmission shaft 305 and bearing sleeve 304, reducing the impact of the external environment on the transmission structure, and improving the stability and service life of the entire adjustable support mechanism 3.
