Description

Technical Field

[0001] This utility model relates to the field of solar energy installation technology, specifically a flexible photovoltaic laying angle measuring device. Background Technology

[0002] Flexible modules, also known as lightweight modules, can be bent at 30 degrees or more. Their main materials include polyester, polyimide, PTFE, fluorinated polymers, etc. These thin film materials can be made into thin film solar cells through printing, spraying and other processes, and then bonded with materials such as PE and PET to form flexible solar panels. Flexible modules are mainly divided into three types: conventional crystalline silicon flexible modules, MWT crystalline silicon flexible modules and thin film flexible modules.

[0003] Flexible photovoltaic panels are typically installed on sloping roofs. During installation, the roof's tilt angle needs to be determined to ensure that the required sunlight angle is met. Therefore, a device capable of measuring the roof's tilt angle is needed.

[0004] CN222048866U discloses a photovoltaic panel installation angle measuring mechanism, relating to the field of photovoltaic panel installation technology. It includes a fixed frame with a groove on the inner wall of its top end. A fixed rod is fixedly connected to the inner wall of the groove. A movable plate is movably fitted onto the wall of the fixed rod. An arc-shaped rod is fixedly connected to the bottom of the movable plate. Multiple scale lines are provided on the wall of the arc-shaped rod. A level is fixedly connected to the bottom of the fixed frame. A cavity is formed in the inner wall of the movable plate, and a ratchet is fixedly fitted onto the wall of the fixed rod within the cavity. This technical solution keeps the level on the fixed frame horizontal. Pulling the handle rotates the movable plate along the wall of the fixed rod until it is flush against the bottom of the photovoltaic panel. The scale lines on the arc-shaped rod can be observed to determine the tilt angle of the movable plate, facilitating the measurement of the photovoltaic panel's installation angle. However, this technical solution is generally suitable for detecting the angle between the solar panel and the support after installation. When measuring the roof tilt angle, it lacks a reference and is therefore inconvenient to use. Utility Model Content

[0008] Furthermore, the horizontal testing section includes an air bubble, which is embedded in the middle of the horizontal section.

[0009] Furthermore, the horizontal testing section includes a fixed rod disposed below the horizontal section and parallel to the hinge rod, with a hoisting rope installed at the top of the fixed rod and a weight fixedly installed at the bottom of the hoisting rope.

[0010] Furthermore, a damping part is provided at the hinge joint between the hinge rod and the fitting part to limit the rotation speed of the hinge rod.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The flexible photovoltaic installation angle measuring device has its fitting part placed parallel to the roof. The horizontal testing part is kept horizontal by rotating the hinge rod. The angle reading part can read the rotation angle of the hinge rod.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] See Figures 1-4 ,

[0024] Example 1: A flexible photovoltaic laying angle measuring device includes a bonding part 1 with a smooth bottom surface. One end of the bonding part 1 is hinged to a hinge rod 2. The end of the hinge rod 2 away from the bonding part 1 is provided with a horizontal part 3 perpendicular to the hinge rod 2. The horizontal part 3 is provided with a horizontal testing part 4 for adjusting the test level by rotating the hinge rod 2. For example, it can be a horizontal sensor. The bonding part 1 is provided with an angle reading part 5 at the hinge end to read the tilt angle of the hinge rod 2.

[0025] The level testing unit 4 includes a bubble bladder 401, which is embedded in the middle of the leveling unit 3. The bubble bladder 401 contains air bubbles in a liquid bladder, and the level is determined by adjusting the air bubbles to the center.

[0026] A damping part 6 is provided at the hinge joint between the hinge rod 2 and the contact part 1 to limit the rotation speed of the hinge rod 2. Since the hinge rod 2 needs to be read, it needs to rotate slowly. By setting the damping part 6 to limit the rotation of the hinge rod 2, it can only rotate when the hinge rod 2 is manually adjusted. The damping part 6 can take various forms, such as using a friction block and a spring, and using the spring to squeeze the friction block to limit the rotation of the hinge axis of the hinge rod 2.

[0027] The angle reading unit 5 includes a protractor 501. The center point of the protractor 501 coincides with the hinge center of the hinge rod 2 and the fitting part 1.

[0028] Furthermore, the angle reading unit 5 also includes a collar 503 sleeved on the outer surface of the hinge shaft where the hinge rod 2 and the fitting part 1 are hinged. A marking rope 504 is fixedly installed on the outer surface of the collar 503. The other end of the marking rope 504 is fixedly connected to the horizontal part 3. The marking rope 504 rotates along the protractor 501. The reading can be read more conveniently through the overlapping part of the marking rope 504 and the protractor 501.

[0029] In embodiment 2, the level testing unit 4 includes a fixed rod 402 located below the leveling unit 3 and parallel to the hinge rod 2. A hoisting rope 403 is installed at the top of the fixed rod 402, and a weight 404 is fixedly installed at the bottom of the hoisting rope 403. The weight 404 pulls the hoisting rope 403 so that it can always be perpendicular to the ground. By rotating the hinge rod 2, the fixed rod 402 can be rotated. When the fixed rod 402 and the hoisting rope 403 coincide, the level can be determined.

[0030] The angle reading unit 5 includes a rotary rheostat 505 embedded in the fitting part 1. The rotary rheostat 505 is concentric with the fitting part 1 and the hinge end of the hinge rod 2. One end of the hinge rod 2 is provided with a connecting part 506, which is fixedly connected to the adjusting end of the rotary rheostat 505. It also includes a display screen 507 for displaying the angle corresponding to the resistance change. The rotary rheostat 505 changes the resistance in the circuit by rotating the adjusting end. The resistance can be changed by rotating the hinge rod 2 and is related to the rotation angle. Therefore, through signal conversion, the specific angle can be displayed on the display screen 507.

[0031] In embodiment 3, the horizontal testing unit 4 includes a bubble bladder 401, which is embedded in the middle of the horizontal part 3. The angle reading unit 5 includes a rotary rheostat 505 embedded in the fitting part 1. The rotary rheostat 505 is concentric with the fitting part 1 and the hinge end of the hinge rod 2. One end of the hinge rod 2 is provided with a connecting part 506, which is fixedly connected to the adjusting end of the rotary rheostat 505. It also includes a display screen 507 for displaying the angle corresponding to the resistance change.

[0032] In embodiment four, the horizontal testing unit 4 includes a fixed rod 402 disposed below the horizontal part 3 and parallel to the hinge rod 2. A hoisting rope 403 is installed at the top of the fixed rod 402, and a weight 404 is fixedly installed at the bottom of the hoisting rope 403. The angle reading unit 5 includes a protractor 501. The center point of the protractor 501 coincides with the hinge center of the hinge rod 2 and the fitting part 1. A pointer 502 pointing to the hinge center is provided in the middle of the surface of the hinge rod 2.

[0033] In use, the fitting part 1 is placed parallel to the roof, and the horizontal testing part 4 is kept horizontal by rotating the hinge rod 2. The rotation angle of the hinge rod 2 can be read by the angle reading part 5. The tilt angle of the roof can be determined by using the rotation angle of the hinge rod 2, which solves the problem of inconvenient angle measurement in the prior art.
