Description

TECHNICAL FIELD

[0001] The application relates to the technical field of photovoltaic installation, in particular to a high-altitude mountain photovoltaic operation platform device. BACKGROUND

[0002] With the rapid development of the global renewable energy industry, the high-altitude mountain area becomes an important space carrier for expanding photovoltaic power station construction because the solar radiation intensity is significantly higher than that of the plain area and the land use form is relatively single, such as a barren slope and sparse forest land. Although the topographic features of the area bring challenges to photovoltaic installation, the altitude advantage makes the proportion of direct solar radiation increase, and the climate characteristics of large diurnal temperature difference are conducive to the stable maintenance of photovoltaic module power generation efficiency. From the perspective of resource development, the high-altitude mountain area is located in the edge zone of the power grid coverage, and the construction of distributed photovoltaic power stations can realize energy supply and power grid extension simultaneously, which meets the demand of power generation and electricity integration in remote areas.

[0003] However, in the process of photovoltaic installation in the high-altitude mountain area, through some installation platforms, although the flatness of the bottom can be adjusted to facilitate workers to work on the platform, different slope steepness may cause the workers to lie on the platform during the installation of photovoltaic, which greatly increases the risk of the working environment of the workers. In addition, in order to ensure the safety of the workers, some work platforms greatly increase the safety lock, which is troublesome during disassembly and causes a lot of time waste. SUMMARY

[0004] The application aims to solve the above technical problems in the prior art and provides a high-altitude mountain photovoltaic operation platform device.

[0005] In order to achieve the above-mentioned purpose, the application adopts the following technical scheme:

[0006] The high-altitude mountain photovoltaic operation platform device comprises a base, an adjusting mechanism for adjusting the position of workers is arranged above the base, a moving block of the adjusting mechanism is fixedly connected with a seat, the back of the seat is fixedly connected with an L-shaped fixed plate, the L-shaped fixed plate is rotatably connected with a ratchet wheel, the ratchet wheel is fixedly connected with a ratchet side gear, the surface of the L-shaped fixed plate is fixedly connected with a U-shaped vertical groove, the side surface of the L-shaped fixed plate is fixedly connected with a fixed pressing block, the bottom of the fixed pressing block is fixedly connected with a spring, the bottom of the spring is fixedly connected with a ratchet pawl, and the ratchet pawl is rotatably connected with the L-shaped fixed plate.

[0007] The above-mentioned technical scheme further comprises:

[0008] The adjusting mechanism comprises a first threaded rod arranged above the base, a sliding plate threadedly connected with the first threaded rod, a tooth column arranged above the sliding plate, an internal gear connected with the tooth column in meshing mode, a fixed box rotationally connected with the internal gear, a worm rotationally connected inside the fixed box, a worm wheel connected with the worm in meshing mode, a cross brace arm rotationally connected with the worm wheel through the fixed box, a second threaded rod rotationally connected inside the cross brace arm, a moving block threadedly connected with the second threaded rod, a seat fixedly connected above the moving block, a fixed block fixedly connected to the surface of the seat, a spring rope arranged on the surface of the fixed block, and a soft rack fixedly connected to the end of the spring rope away from the fixed block.

[0009] A lifting arm is fixedly connected above the base.

[0010] A plurality of supporting legs are arranged at the bottom of the base, and universal wheels are fixedly connected to the bottom of the supporting legs.

[0011] A rocker is rotationally connected to the side surface of the L-shaped fixed plate, and a ratchet wheel is fixedly connected with the rocker through the L-shaped fixed plate.

[0012] A motor is fixedly connected above the sliding plate, and a tooth column is fixedly connected to the output end of the motor.

[0013] The motor directly drives the rotation of the tooth column, realizes the meshing transmission of the tooth column and the gear such as the internal gear, and can accurately control the angle adjustment or height lifting of the working platform. The structure directly converts the motor power into rotary motion, avoids the energy loss of traditional mechanical transmission, improves the angle calibration efficiency during the installation of the photovoltaic support, and is especially suitable for the orientation fine adjustment of the photovoltaic array in the middle and high altitude mountain area, and ensures that the components receive the optimal sunshine angle.

[0014] A motor for driving the rotation of the first threaded rod is arranged on the side surface of the base.

[0015] The motor on the side surface of the base drives the rotation of the first threaded rod, and the sliding plate is transversely translated along the base through the threaded cooperation of the threaded rod and the sliding plate. This design makes the working platform flexible in the horizontal direction, and the working platform can cover a larger working range without the need of overall carrying equipment, and is especially suitable for the rapid positioning of different slope positions during the installation of the photovoltaic array in the mountain area, and reduces the repeated displacement operation caused by the limitation of the terrain.

[0016] The sliding plate is slidably connected with the base, and the fixed box is slidably connected with the tooth column.

[0017] The sliding fit of the sliding plate on the base, combined with the sliding of the fixed box along the tooth column, forms a horizontal movement and vertical adjustment combined motion structure. When the mountain terrain appears ups and downs, the sliding plate can adjust the position horizontally, and the fixed box slides along the tooth column to adjust the working height, so that the platform can still maintain the horizontal operation surface on the uneven ground, avoiding the tilting risk of the traditional platform caused by the terrain difference.

[0018] The cross support arm is rotationally connected with the second threaded rod, and the moving block is slidingly connected with the cross support arm.

[0019] When the second threaded rod rotates, the moving block slides forward and backward on the cross support arm, which can adjust the distance between the moving block and the mountain slope in real time, and adapt to different slope environments. For example, when working on a steep slope, the moving block moves backward to increase the platform support span and enhance the wind resistance stability; when working on a gentle slope, the moving block moves forward to shorten the operation distance from the photovoltaic support, and improve the installation convenience.

[0020] The present application has the following beneficial effects:

[0021] 1、In the present application, the independent lifting bottom columns at the bottom of the base cooperate with the universal wheels, so that the height of each bottom column can be adjusted in real time according to the steepness of the mountain slope, so that the operation platform can always maintain a horizontal state. This design avoids the tilting of the traditional platform caused by the terrain ups and downs, and the operator does not need to crouch or bend over for work, but directly adjusts the pitch through the seat fixing system and the multi-angle adjustment mechanism, such as the self-locking pitch adjustment of the worm and the worm gear, to maintain a straight operation posture, thereby reducing the risk of body imbalance during high-altitude work. At the same time, the rotatable hoisting function of the lifting arm can adapt to the precise positioning of the slope photovoltaic support, reducing the dangerous actions caused by the position deviation of the operator.

[0022] 2、In the present application, the dynamic self-locking structure of the ratchet and pawl is used in cooperation with the quick connection design of the soft rack and spring rope. When disassembly is needed, the soft rack and the ratchet gear can be disengaged by manually lifting the pawl and rotating the rocker in the opposite direction, achieving the disassembly of the safety fixing device within seconds, saving a lot of disassembly time compared with the traditional bolt type or buckle type safety lock. This structure uses the elastic reset characteristic of the spring to complete the locking through the automatic engagement of the ratchet teeth and the pawl during work, without the need for additional tools, which not only ensures the safety of high-altitude work, but also significantly improves the installation efficiency.
