Description

Technical Field

[0001] The invention belongs to the technical field of level measurement, and in particular relates to a level measuring instrument for photovoltaic panel installation. Background Art

[0002] Levels are mainly divided into two types: bubble levels and laser levels. Bubble levels are traditional level measurement tools that determine whether the surface is level by observing the position of the bubble in the tube. They have limited accuracy and stability, and are not easy to operate over long distances or over large areas. Laser levels use laser beams to project horizontal lines. They have the advantages of high precision, high stability, and easy operation. They are suitable for occasions that require precise measurement, such as photovoltaic installations.

[0003] The Chinese patent discloses a multifunctional laser level measuring instrument (CN114279407B); it includes a placement frame, a base, a counterweight, a controller, a rotating assembly, a rotating disk and a measuring instrument body. First, the multifunctional laser level measuring instrument is placed on the ground. The counterweight is affected by gravity so that the measuring instrument body always remains vertical. When it is necessary to adjust the measuring direction of the measuring instrument body to be consistent with the object to be measured, the rotating assembly is started to drive the rotating disk to rotate on the base. The distance between the device and the object to be measured is measured by the infrared distance measuring sensor until the measured distance is the minimum, indicating that the measuring direction of the measuring instrument body is consistent with the object to be measured. With the above structure, the measuring direction of the measuring instrument body can be automatically adjusted to be consistent with the object to be measured, and no manual adjustment is required, which is more convenient to operate. After the horizontal measuring instrument is placed in the appropriate position, the horizontality of the measuring instrument needs to be adjusted. However, most of the current horizontal measuring instruments do not have the function of automatic adjustment. When the offset angle is too large, it takes a long time to adjust. While reducing the working efficiency of the horizontal measuring instrument, it also reduces the installation efficiency of the photovoltaic panel.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, a leveling component is provided, and the positioning pin is pulled out from the positioning hole. Under the action of the leveling block, the connecting rod is always in a vertical state with the ground, thereby driving the rotating plate on the rotating block to rotate along the top side wall of the first fixed plate and the second fixed plate. At this time, the rotating block will drive the measuring head to rotate synchronously, thereby making the measuring head parallel to the ground, and then finely adjust the measuring head. After the adjustment, the positioning pin is inserted into the positioning hole under the action of the positioning spring, thereby fixing the rotating block by fixing the rotating disk, thereby keeping the measuring head stationary, realizing the automatic leveling function of the horizontal measuring instrument. At the same time, the structure is simple and easy to operate, thereby improving the leveling efficiency of the horizontal measuring instrument and further improving the installation efficiency of the photovoltaic panel.

[0022] 2. In the present invention, an adjustment component and a stabilizing component are provided, and the measuring instrument is moved to an appropriate position through the base, and then the adjusting motor drives the first threaded column to rotate, and the second threaded column is driven to rotate synchronously under the action of the sprocket wheel and the toothed chain, and the threaded sleeve drives the support rod to move under the action of the thread, and then drives the support plate to move synchronously to adjust the height of the measuring head. When the first threaded column and the second threaded column rotate, they will drive the transmission gear to rotate synchronously. At this time, under the action of the fixed rack, the stabilizing plate is driven to move outward on both sides of the base through the first fixed rod. When the stabilizing plate moves, the second fixed rod drives the limit sleeve rod to move on the limit rod. The outer surface of the horizontal measuring instrument is moved to pull the pin out of the socket, and the movable rod is driven to move through the fixing ring under the action of the connecting spring. When the movable rod moves, the supporting foot is driven to move synchronously. After the supporting foot contacts the ground, the pin is inserted back into the socket to fix the movable rod, thereby supporting the stabilizing plate in the potholes, facilitating the adjustment of the height of the horizontal measuring instrument, increasing the contact area between the instrument and the ground while adjusting the height, further improving the stability of the instrument, and avoiding the shaking of the horizontal measuring instrument due to the increase in height, thereby improving the accuracy of the horizontal measuring instrument, and then improving the accuracy of the photovoltaic panel installation.

[0023] 3. In the present invention, a counterweight assembly is provided, and the threaded sleeve will drive the connecting plate to move synchronously when it moves. When the connecting plate moves, it drives the fixed assembly to move through the mounting plate. When the fixed assembly moves up, the connecting rope is in a relaxed state. Therefore, under the support of the pulley, the mounting assembly drives the counterweight block to move to the bottom of the fixed box on the slide rod. When the fixed assembly descends, the connecting rope will pull the mounting assembly upward under the support of the pulley, thereby moving the counterweight block to the top of the fixed box, changing the position of the weight according to the height change of the horizontal measuring instrument, thereby improving the stability of the horizontal measuring instrument during use. Under the dual action of the stabilizing assembly, the shaking and tipping of the horizontal measuring instrument during use are reduced as much as possible, thereby improving the measurement accuracy of the instrument and also ensuring the accuracy of the installation position of the photovoltaic panel.

[0058] The embodiment of the present invention provides a level measuring instrument for photovoltaic panel installation, and its working principle is as follows: the measuring instrument is moved to an appropriate position through the base 1, and then the motor 31 is adjusted to drive the first threaded column 32 to rotate, and the second threaded column 36 is driven to rotate synchronously under the action of the sprocket wheel 35 and the toothed chain, and the threaded sleeve 33 drives the support rod 34 to move under the action of the thread, and then drives the support plate 2 to move synchronously to adjust the height of the measuring head 7; the positioning pin 410 is pulled out of the positioning hole 46, and under the action of the leveling block 44, the connecting rod 43 is always in a vertical state with the ground, thereby driving the rotating plate 420 on the rotating block 42 to move along the top side wall of the first fixed plate 40 and the second fixed plate 41 The measuring head 7 is rotated, and the rotating plate 420 on the rotating block 42 drives the measuring head 7 to rotate synchronously, so that the measuring head 7 is parallel to the ground. Then, the measuring head 7 is finely adjusted. After the adjustment, the positioning pin 410 is inserted into the positioning hole 46 under the action of the positioning spring 49 to fix the rotating disk 45. Since the rotating disk 45 is fixedly connected to the rotating block 42 through the connecting shaft 9, the rotating block 42 and the rotating plate 420 on the rotating block 42 are fixed, so that the measuring head 7 remains stationary. When the first threaded column 32 and the second threaded column 36 rotate, they will drive the transmission gear 8 to rotate synchronously. At this time, the stabilizing plate 51 is driven by the first fixing rod 52 under the action of the fixed rack 53. When the stabilizing plate 51 moves outward on both sides of the base 1, the second fixing rod 54 drives the limiting sleeve rod 55 to move on the outer surface of the limiting rod 56; the latch 58 is pulled out of the socket 511, and the movable rod 57 is driven to move through the fixing ring 59 under the action of the connecting spring 510, and the movable rod 57 drives the supporting foot 512 to move synchronously when it moves, and after the supporting foot 512 contacts the ground, the latch 58 is inserted back into the socket 511 to fix the movable rod 57, thereby supporting the stabilizing plate 51 in the pit; the threaded sleeve 33 drives the connecting plate 65 to move synchronously when it moves, and the connecting plate 65 drives the fixing assembly 67 to move through the mounting plate 66 when it moves, and the fixing assembly When 67 moves up, the connecting rope is in a relaxed state. Therefore, under the support of the pulley 69, the installation component 64 drives the counterweight 63 to move to the bottom of the fixed box 61 on the slide bar 62. When the fixed component 67 descends, the connecting rope will pull the installation component 64 upward under the support of the pulley 69, so that the counterweight 63 moves to the top of the fixed box 61. The position of the center of gravity of the horizontal measuring instrument is changed according to the height change of the counterweight 63 on the horizontal measuring instrument, which improves the stability of the horizontal measuring instrument during use. Under the dual action of the stabilizing component, the shaking and tipping of the horizontal measuring instrument during use are reduced as much as possible, which improves the measurement accuracy of the instrument while also ensuring the accuracy of the installation position of the photovoltaic panel.
