Description

Technical Field

[0001] This invention belongs to the field of wind measurement tower technology, and specifically relates to a wind measurement tower that facilitates sensor maintenance. Background Technology

[0002] Meteorological equipment such as automatic weather stations, unmanned weather stations, and wind measurement towers monitor wind direction and speed by mounting wind direction and speed sensors on 10-meter-high iron towers. Since these sensors require calibration every two years, it necessitates climbing to the top of the tower to remove the sensor, transport it to the ground, and then transporting the replacement sensor back up for installation. When a wind direction and speed sensor malfunctions, repairs also require climbing to the top of the tower. This process is extremely cumbersome and poses significant safety hazards, especially in Northeast China during winter when temperatures drop to below -30 degrees Celsius, and snowfall makes the tower extremely slippery and prone to icing, further complicating maintenance and posing a serious safety risk to maintenance personnel. Furthermore, meteorological equipment collects data every minute; malfunctioning wind direction and speed sensors must be repaired as quickly as possible. Otherwise, prolonged data gaps and irreparable historical data loss occur, and the repeated trips up and down the tower for repairs cannot guarantee timely restoration. Summary of the Invention

[0003] To overcome the above-mentioned technical problems, the present invention provides a wind measurement tower that facilitates sensor maintenance.

[0004] The present invention adopts the following technical solution: A wind measurement tower for easy sensor maintenance includes a tower body with a top platform extending beyond the top of the tower. A lifting rail connects to the rear of the tower body, slidably connecting to a lifting seat. A support rod is fixedly connected to the end of the lifting seat furthest from the tower body, and a transverse sensor arm is fixedly connected to the top of the support rod. When the lifting seat is at its upper limit, the sensor arm is higher than the top platform. A motor is mounted on the bottom of the top platform, connected to a reduction gearbox. The reduction gearbox is connected to a rope winding wheel with a steel wire rope connected to the lifting seat. A fixed box is located at the top rear of the tower body, with a docking groove at its bottom. A connector is located at the end of the lifting seat near the tower body; when the lifting seat is at its upper limit, the connector is located within the docking groove. A second motor is located inside the fixed box, connected to a transverse lead screw via a reduction gearbox. The lead screw thread drives a pin, and the connector has a transverse insertion hole. A female connector is located above the front end of the connector, and a male connector is located above the pin.

[0005] Preferably, the lifting slide rail includes two parallel rails, one on the left and one on the right, and the lifting seat has two sliding grooves, one on the left and one on the right. Each sliding groove partially surrounds the corresponding rail.

[0016] A wind measurement tower for easy sensor maintenance includes a tower body 1. A top platform 2 is installed at the top of the tower body 1, with its edge extending beyond the top of the tower body 1. A lifting rail 3 is connected to the rear side of the tower body 1, and the lifting rail 3 is slidably connected to a lifting seat 4. A support rod is fixedly connected upwards to the end of the lifting seat 4 furthest from the tower body 1. A transverse sensor arm 20 is fixedly connected to the top of the support rod. When the lifting seat 4 is at its upper stop point, the sensor arm 20 is higher than the top platform 2. A motor 15 is mounted on the bottom surface of the top platform 2. The motor 15 is connected to a reduction gearbox 5, which is connected to a rope winding wheel. A rain cover 14 is provided outside the rope winding wheel, and a steel wire rope 6 is provided on the rope winding wheel, connecting to the lifting seat 4. A fixing box 7 is located at the top rear side of the tower body 1. Two docking slots 701 are opened at the bottom of the fixing box 7. The lifting seat 4... Two connectors 401 are provided near one end of the tower body 1, one on the left and one on the right. When the lifting seat 4 is at the upper stop point, the connectors 401 are located in the docking groove 701. The fixed box 7 is equipped with a second motor 8. The second motor 8 is connected to a horizontal double-headed lead screw 10 through a reduction gearbox 9. Each end of the lead screw 10 is threaded with a pin 11. The threads of the two pins 11 are opposite. The two pins 11 are slidably set in the horizontal slide rail inside the fixed box 7. The connectors 401 have horizontal insertion holes. When the lifting seat 4 is at the upper stop point, the insertion holes are aligned with the slide rail. A female terminal block 13 is provided above the front end of the connectors 401. A male terminal block 12 is provided above the pins 11. The fixed box 7 has grooves above the docking groove 701 and the slide rail, respectively, for the female terminal block 13 and the male terminal block 12. The lower section of tower body 1 is equipped with a controller 18 and a battery 19. The controller 18 controls the operation of motor 15 and motor 8. The controller 18 controls the operation of the two motors, which in turn controls the lifting, lowering, locking, and unlocking of the lifting seat 4. The battery 19 is connected to the photovoltaic panel, which supplies power to the system.

[0017] The lifting slide rail 3 includes two parallel rails 301, one on the left and one on the right. The lifting seat 4 has two sliding grooves 403, one on the left and one on the right. The openings of the two sliding grooves 403 face each other. Each sliding groove 403 partially surrounds the corresponding rail 301. An ice-removing shovel 402 is set at the bottom of the sliding groove 403 along the contour line of the groove cross section. The tip of the ice-removing shovel 402 is in contact with the rail 301. After rain or snow, the rail 301 freezes and accumulates snow. The ice-removing shovel 402 can effectively remove the ice and snow.

[0018] To prevent rain and snow from entering between the rail 301 and the chute 403 and causing ice formation that would hinder the lowering of the lifting seat 4, an extension section 16 is provided at the top of the chute 403 along the chute cross-section outline.

[0019] The method for repairing wind measurement tower sensors, using the aforementioned wind measurement tower that facilitates sensor repair, includes the following steps: S1. By controlling the controller 18, start the motor 2 8. The motor 2 8 drives the lead screw 10 through the reduction gearbox 2 9 to move the two pins 11 inward and bring them closer together until the pins 11 disengage from the socket, releasing the lock on the lifting seat 4. At the same time, the male terminal block 12 and the female terminal block 13 separate, disconnecting the circuit connection of the sensor. S2. Start motor 15. Motor 15 drives the rope wheel to release the rope through gearbox 5. The lifting seat 4 descends by gravity. The sensor arm 20 descends along with it. When descending, the de-icing shovel 402 removes the ice and snow on the rail 301 that affect the sliding of the lifting seat 4. S3. After the lifting seat 4 and sensor cross arm 20 reach the lower stop point, the sensor is repaired; S4. After maintenance, motor 15 operates, the rope reel winds up the rope, and the lifting seat 4 is pulled up to the upper stop point again. Then, motor 2 drives the two pins 11 to pass through the insertion hole and lock the lifting seat 4 again. At the same time, the male terminal block 12 and the female terminal block 13 are plugged in to restore the circuit connection of the sensor.
