Description

Technical Field

[0001] The utility model relates to a device for lifting photovoltaic modules, which is applicable to the technical field of new energy construction. Background Art

[0002] In some photovoltaic new energy projects, the minimum ground clearance requirement for photovoltaic modules is 2.4 meters or more. However, due to the heavy weight and flat rectangular shape of the modules themselves, component hidden cracks, breakage, and injury accidents are likely to occur during the handling and lifting of the components. Manually handling and lifting the components during project construction is not conducive to the progress and quality of project construction. Moreover, the field topography is rugged and complex, and mobile scaffolding cannot be used in some areas, resulting in extremely low operation efficiency. Summary of the Invention

[0037] Embodiment 1: The utility model is a stand-on photovoltaic module lifting device, comprising a frame, a climbing platform, a module platform, a control host, etc.

[0038] In this example, tires and a driving mechanism for driving the tires to rotate are installed at the bottom of the frame, wherein the tires are 14-inch off-road tires to be suitable for a variety of complex terrains.

[0039] In this embodiment, the climbing platform is installed on the frame via a first lifting mechanism (with a lifting frame). The first lifting mechanism can drive the climbing platform to move up and down. The climbing platform is divided into a personnel standing area and a component placement area. The personnel standing area provides a foothold for component installers when installing photovoltaic components, and the component placement area is used to place photovoltaic components.

[0040] In this example, a component platform is installed in the component placement area via a second lifting mechanism. The second lifting mechanism adopts a scissor-type lifting mechanism, which can drive the component platform to move up and down. The component platform is used to stack photovoltaic components layer by layer.

[0041] In this embodiment, a photoelectric sensor is installed at a certain height above the climbing platform. The photoelectric sensor is used to sense whether there are photovoltaic components on the component platform at this height to ensure that there are photovoltaic components at the installation position that is convenient for component installers to grab and install photovoltaic components.

[0042] In this example, a through-beam sensor is installed within a certain height range on the component platform. The certain height range is determined based on the thickness of a single photovoltaic component. That is, when there is at least one photovoltaic component on the component platform, the signal of the through-beam sensor is blocked, otherwise the signal of the through-beam sensor is turned on, thereby realizing detection of whether there is a photovoltaic component within a certain height range above the component platform.

[0043] In this embodiment, a control host is installed at one end of the frame. The control host is equipped with a liquid crystal display and a multi-function handle. The multi-function handle has buttons such as a power switch, emergency stop, forward, backward, up, down, backward tilt, forward tilt, and stop, as well as a liquid crystal display (which can display information such as the height of the climbing frame and the number of photovoltaic components installed this time) to ensure safety during the transportation and lifting of components.

[0044] In this example, the control host is connected to the tire driving mechanism, the first lifting mechanism, the second lifting mechanism, the photoelectric sensor and the through-beam sensor and other circuits. The movement of the entire device can be controlled by the driving mechanism; the lifting and lowering of the climbing platform can be controlled by the first lifting mechanism; the lifting and lowering of the component platform can be controlled by the second lifting mechanism; the lifting and lowering of the component platform can be controlled by the photoelectric sensor in cooperation with the second lifting mechanism to ensure that there are photovoltaic components at the specified height during the component installation process; the lifting and lowering of the component platform can be controlled by the through-beam sensor in cooperation with the second lifting mechanism to automatically control the descent of the component platform when there are no photovoltaic components on the component platform.

[0045] In this embodiment, a pedal is arranged on the frame, and the pedal is arranged beside the control host for the operator who operates the control host to stand. A foldable guardrail is installed on the control host to protect the operator on the pedal.

[0046] The specific operation method of this embodiment is as follows:

[0047] After the staff places the PV modules on the module platform on the climbing platform (because one PV string generally has less than 28 modules, a maximum of 28 modules can be loaded at a time), they open the folding pedal and foldable guardrail, and operate the forward gear of the multi-function handle to transport the modules to the module installation location;

[0048] The component installer climbs onto the scaffold and fastens the safety belt. Then, the construction worker operates the up button on the handle, and through the chain drive on the lifting frame, the elevated platform is lifted to an appropriate position. Next, the stop button is pressed, and the installer on the elevated platform takes the topmost photovoltaic component from the component platform and installs it onto the photovoltaic support.

[0049] After the component installer takes one component, the photoelectric sensor senses that there is no component at the position of the topmost component, and the second lifting mechanism operates to lift the component platform to facilitate the installer to take the next component.

[0050] After all the components are installed in sequence, when the opposed sensors on the placement platform detect that there are no components, the component platform automatically descends to the plane of the elevated platform.

[0051] After the component installer completes the installation of this batch of components, the construction worker operates the down button to lower the elevated platform to the ground. The installer gets off the vehicle and then proceeds to the next operation.

[0052] Embodiment 2: This embodiment is an electric-driven sit-on type photovoltaic component lifting device, which has basically the same structure as Embodiment 1. The difference is only that in this example, a cockpit is configured on the vehicle frame, and a control host and a control unit for controlling the operation of the vehicle frame are provided in the cockpit; in this example, the drive mechanism adopts electric drive.

[0053] Embodiment 3: This embodiment is a diesel-driven sit-on type photovoltaic component lifting device, which has basically the same structure as Embodiment 2. The difference is only that in this example, the drive mechanism adopts diesel drive.

[0054] Embodiment 4: This embodiment is a hand-pushed type photovoltaic component lifting device, including: a vehicle frame, a component platform, a control host, etc.

[0055] In this example, tires are installed at the bottom of the vehicle frame; the component platform is installed on the vehicle frame through the second lifting mechanism, and the component platform can be used for stacking photovoltaic components; the control host is installed on the vehicle frame and is electrically connected to the second lifting mechanism.

[0056] In this embodiment, a handle is configured on the vehicle frame, and the position of the handle corresponds to the position of the control host, which is convenient for the operator to push and operate the device.

[0057] In this example, opposed sensors are installed on the component platform, and the opposed sensors are electrically connected to the control host, and are used to detect whether there are photovoltaic components within a certain height range above the component platform, and the certain height range is determined based on the thickness of a single photovoltaic component.

[0058] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
