Description
Technical Field
[0001] This utility model relates to the field of photovoltaic installation technology, specifically a portable positioning and calibration device for photovoltaic array construction. Background Technology
[0002] A photovoltaic array is a system composed of multiple photovoltaic modules arranged in a certain way. It is the core component of a solar photovoltaic power generation system. During the construction of a photovoltaic array, positioning and calibration equipment is required to ensure the installation accuracy of the photovoltaic array.
[0003] Construction workers typically use traditional positioning and calibration devices to determine the distance between two photovoltaic brackets, and then use this distance to define the installation range of the photovoltaic modules, thereby determining the placement of the modules.
[0004] However, in actual construction, due to the size of the positioning and calibration equipment, it is impossible to ensure that the laser emitter of the positioning and calibration equipment is located in the center of the photovoltaic support. However, the center of the photovoltaic support is the clearly defined positioning origin in the design drawings. If the laser emitter deviates from the center, the laser line it emits will become an "eccentric reference". When the subsequent components use this line as a reference, there will be an overall offset. Moreover, photovoltaic arrays are usually composed of hundreds or even thousands of components. Even a small offset can lead to a cumulative offset of tens of centimeters for the entire array, which seriously deviates from the design position and greatly reduces the installation accuracy and construction efficiency of the photovoltaic array. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a portable positioning and calibration device for photovoltaic array construction. This solves the problem that, during actual construction, the laser emitter of the positioning and calibration device, due to its inherent size, cannot be guaranteed to be centered on the photovoltaic support. However, the center of the photovoltaic support is the clearly defined positioning origin in the design drawings. If the laser emitter deviates from the center, the emitted laser line becomes an "eccentric reference." When subsequent components use this line as a reference, an overall offset will occur. Furthermore, photovoltaic arrays typically consist of hundreds or even thousands of components; even a small offset can lead to a cumulative offset of tens of centimeters, severely deviating from the design position and significantly reducing the installation accuracy and construction efficiency of the photovoltaic array.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable positioning and calibration device for photovoltaic array construction, comprising a laser positioning instrument, wherein an adjustment mechanism is provided on the back of the laser positioning instrument; the adjustment mechanism includes a slide rail, a slider, a clamping plate, and an adjustment rod; the slide rail is located on the back of the laser positioning instrument, a slider is slidably connected to the inner wall of the slide rail, a clamping plate is provided below the slider, the bottom of the clamping plate abuts against the inner wall of the slide rail, a first adjustment rod is threadedly connected to the inner wall of the clamping plate, the outer wall of the adjustment rod is rotatably connected to the inner wall of the slider through a sealed bearing, and the end of the adjustment rod penetrates the bottom of the slide rail and is movably connected to the bottom of the slide rail.
[0007] Preferably, a fixing mechanism is provided on the back of the slide; the fixing mechanism includes a fixing seat, a fixing rod, a fixing plate and an anti-slip pad; the fixing seat is fixedly connected to the back of the slide, the fixing rod is threadedly connected to the side wall of the fixing seat, the fixing plate is provided inside the fixing seat, the fixing plate is rotatably connected to the end of the fixing rod through a sealed bearing, and an anti-slip pad is fixedly connected to the side of the outer wall of the fixing plate away from the fixing rod.

[0011] Beneficial effects
[0012] This invention provides a portable positioning and calibration device for photovoltaic array construction. It offers the following advantages: This portable positioning and calibration device, through the cooperation of a slide rail, slider, clamping plate, and adjusting rod, adjusts the position of the laser emitter, ensuring that the "reference point" for positioning and calibration completely coincides with the "design origin" of the photovoltaic system. This ensures the reliability of the laser line from the source, avoiding cumulative errors caused by eccentricity, simplifying the calibration logic during construction, and allowing subsequent component installation to be completed simply by "aligning the lines."

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0020] In actual construction, due to the size of the positioning and calibration equipment, it is impossible to ensure that the laser emitter of the positioning and calibration equipment is located in the center of the photovoltaic support. However, the center of the photovoltaic support is the clearly defined positioning origin in the design drawings. If the laser emitter deviates from the center, the laser line it emits will become an "eccentric reference". When the subsequent components use this line as a reference, there will be an overall offset. Moreover, photovoltaic arrays are usually composed of hundreds or even thousands of components. Even a small offset can lead to a cumulative offset of tens of centimeters for the entire array, which seriously deviates from the design position and greatly reduces the installation accuracy and construction efficiency of the photovoltaic array.
[0021] In view of this, the present invention provides a portable positioning and calibration device for photovoltaic array construction. This portable positioning and calibration device for photovoltaic array construction, through the cooperation of a slide rail, a slider, a clamping plate and an adjusting rod, realizes the adjustment of the position of the laser emitter, so that the "reference point" of positioning and calibration completely coincides with the "design origin" of the photovoltaic system. This ensures the reliability of the laser line from the source, avoids the cumulative error caused by eccentricity, simplifies the calibration logic in construction, and allows subsequent component installation to "meet the standard by aligning the lines". Ultimately, it improves the installation accuracy and construction efficiency of the photovoltaic array, and provides a unified reference for later system operation and maintenance.
[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0023] Example 1, by Figure 1-4 It is known that a portable positioning and calibration device for photovoltaic array construction includes a laser positioning instrument 1, and an adjustment mechanism is provided on the back of the laser positioning instrument 1. The adjustment mechanism includes a slide 2, a slider 3, a clamping plate 4, and an adjustment rod 5. The slide 2 is provided on the back of the laser positioning instrument 1, the slider 3 is slidably connected to the inner wall of the slide 2, the clamping plate 4 is provided below the slider 3, the bottom of the clamping plate 4 is pressed against the inner wall of the slide 2, the inner wall of the clamping plate 4 is threadedly connected to the first adjustment rod 5, the outer wall of the adjustment rod 5 is rotatably connected to the inner wall of the slider 3 through a sealed bearing, and the end of the adjustment rod 5 passes through the bottom of the slide 2 and is movably connected to the bottom of the slide 2.
[0024] In the specific implementation process, it is particularly worth noting that the model of the laser locator 1 can be selected according to actual needs as long as it meets the work requirements. For example, it can be 9319-3XG-Li&9319-5XG-Li. It has a built-in lithium battery to provide power for it. The slideway 2 is generally similar to a cuboid, and its material can be selected as aluminum alloy. Its front is processed with a through groove whose cross-section is similar to a 'convex' shape, and its bottom is processed with a rectangular through groove. The rectangular through groove is connected to the 'convex' shaped through groove. The slider 3 has a cross-section similar to a T shape, and its material can be selected as nylon PA66. Its top is processed with a through hole that penetrates its bottom, and two sealed bearings are fixedly connected inside the through hole. The pressing plate 4 is generally similar to a rectangular plate, and its material can be selected as stainless steel. Its top is provided with a circular through hole, and internal threads are processed inside the through hole. The adjusting rod 5 is generally similar to an extended bolt. A small part of its outer wall is processed with external threads, and the rest extends into the through hole of the slider 3 and is rotationally connected through the sealed bearing. When the position of the laser locator 1 needs to be adjusted, the construction worker holds the bottom of the adjusting rod 5 with a tool and rotates the adjusting rod 5 clockwise. Due to the limitation of the inner wall shape of the slideway 2, the clockwise rotation of the adjusting rod 5 drives the pressing plate 4 to rise. The pressing plate 4 leaves the bottom of the inner wall of the slideway 2 and approaches the slider 3. At the same time, due to the disappearance of the pressing force of the pressing plate 4, the slider 3 is affected by gravity and moves downward, thus leaving the top of the inner wall of the slideway 2 and approaching the pressing plate 4. At this time, the adjusting mechanism is unlocked, and the slider 3 and the pressing plate 4 can be driven by the adjusting rod 5 to move inside the slideway 2. When the laser locator 1 reaches the specified position, the construction worker rotates the adjusting rod 5 counterclockwise. The adjusting rod 5 drives the pressing plate 4 to move downward to achieve re-clamping. At this time, the adjusting mechanism is locked. Through the cooperation of the slideway 2, the slider 3, the pressing plate 4 and the adjusting rod 5, the "reference point" of the positioning and calibration is completely coincident with the "design origin" of the photovoltaic system, ensuring the reliability of the laser line from the source. It can not only avoid the cumulative error caused by eccentricity but also simplify the calibration logic in construction, making the subsequent component installation "meeting the standard by aligning with the line", thus improving the installation accuracy and construction efficiency of the photovoltaic array;
[0025] Furthermore, a fixing mechanism is provided on the back surface of the slideway 2; the fixing mechanism includes a fixing seat 6, a fixing rod 7, a fixing plate 8 and an anti-slip pad 9; the fixing seat 6 is fixedly connected to the back surface of the slideway 2, the side wall of the fixing seat 6 is threadedly connected with the fixing rod 7, an inner fixing plate 8 is arranged inside the fixing seat 6, the fixing plate 8 is rotationally connected to the end of the fixing rod 7 through a sealed bearing, and an anti-slip pad 9 is fixedly connected to one side of the outer wall of the fixing plate 8 away from the fixing rod 7;
[0026] In the specific implementation process, it is worth noting that the fixing base 6 has a U-shaped frame structure with threaded holes on its side walls, and its material can be aluminum alloy. The fixing rod 7 is similar to a bolt and is made of stainless steel, with external threads machined on its outer wall to connect with the side wall of the fixing base 6. The fixing plate 8 is similar to a square plate and can be made of stainless steel. The anti-slip pad 9 is the same shape as the fixing plate 8 and can be made of silicone, with a serrated texture on its surface to enhance friction with the photovoltaic bracket and prevent the device from sliding. When it is necessary to install this positioning and calibration device on the photovoltaic bracket... At this time, the construction personnel rotate the fixing rod 7 clockwise, which moves the fixing plate 8. The fixing plate 8 moves the anti-slip pad 9 away from the other inner wall of the fixing seat 6. When the distance is large enough, the inner wall of the fixing seat 6 is pressed against the outer wall of the photovoltaic bracket. At the same time, the fixing rod 7 is rotated counterclockwise, which moves the fixing plate 8. The fixing plate 8 moves the anti-slip pad 9 closer to the other outer wall of the photovoltaic bracket until it is pressed against the outer wall of the photovoltaic bracket. At this time, the portable positioning and calibration device for photovoltaic array construction is firmly fixed on the photovoltaic bracket, thereby improving the stability of the portable positioning and calibration device for photovoltaic array construction.
[0027] Furthermore, a connecting seat 10 is fixedly connected to the front of the slider 3, a first magnetic component 11 is fixedly connected to the inner wall of the connecting seat 10, a second magnetic component 12 is inserted into the inner wall of the connecting seat 10, the second magnetic component 12 is fixedly connected to the outer wall of the first magnetic component 11 on the side away from the inner wall of the connecting seat 10, the outer wall of the second magnetic component 12 on the side away from the first magnetic component 11 is fixedly connected to the outer wall of the laser positioning device 1, and the outer wall of the laser positioning device 1 is in contact with the outer wall of the connecting seat 10.
[0028] In the specific implementation process, it is worth noting that the connecting seat 10 is generally similar to a cuboid, with a circular groove machined on its front side. Its material can be engineering plastic. The first magnetic component 11 and the second magnetic component 12 are made of the same material, both being neodymium iron boron strong magnets. They are fixed together by the principle of opposite poles attracting each other. Furthermore, a connecting plate is fixedly connected to the front side of the second magnetic component 12, which is fixed to the back of the laser positioning device 1. Construction personnel can directly replace the laser positioning device 1 through the first magnetic component 11 and the second magnetic component 12, improving the convenience and efficiency of replacement and realizing an increase in the maintenance speed of the portable positioning and calibration device for photovoltaic array construction.
[0029] Example 2, by Figure 1-4 It can be seen that a limiting hole 13 is opened on the front of the connecting seat 10, and a limiting rod 14 is inserted into the inside of the limiting hole 13. The limiting rod 14 is fixedly connected to the outer wall of the laser positioning instrument 1.
[0030] In the specific implementation process, it is worth noting that the limiting hole 13 is a cylindrical groove, and there are four of them, located around the circular groove on the front of the connecting seat 10. The shape and number of the limiting rod 14 are the same as those of the limiting hole 13. Its material can be plastic. The limiting hole 13 and the limiting rod 14 help the construction personnel to replace the laser positioning instrument 1 more quickly, thereby improving the installation convenience of the portable positioning calibration device for photovoltaic array construction.
[0031] Furthermore, the front of the fixing base 6 is provided with a scale 15, and the front of the scale 15 is provided with a laser emitter 16, which is fixedly connected to the outer wall of the connecting base 10.
[0032] In the specific implementation process, it is worth noting that the scale 15 is machined on the front of the fixed base 6, and the smallest unit can be millimeters. The laser emitter 16 is used to indicate the position of the laser positioning instrument 1 and works in conjunction with the scale 15. Its model can be S0-P81W-1DD6SV4-FKXR. It has a built-in battery. Through specific numbers, the construction personnel can more intuitively observe the position of the laser positioning instrument 1, which makes it easier for the staff to locate the position of the laser positioning instrument 1 faster and more accurately, thereby improving the reliability of the portable positioning calibration device for photovoltaic array construction.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
