Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic installation auxiliary tools, in particular to a simple oil resistance plumb bob instrument. Background Art

[0002] In photovoltaic installation projects, the angle of the photovoltaic bracket directly affects the installation angle of the photovoltaic panels in the later stage. The installation angle of the photovoltaic panels is directly related to the lighting angle, which directly affects the power generation efficiency of the photovoltaic panels.

[0003] During the construction of photovoltaic brackets, a horizontal bracket is generally set up first. The horizontal bracket can provide a horizontal reference surface, and then an adjustment bracket is constructed and set on the reference surface. The photovoltaic panels are set on the adjustment bracket, and the horizontal reference surface provides a horizontal reference for the subsequent adjustment bracket. When the error of the horizontal reference surface is large, it will cause the adjustment amplitude of the subsequent adjustment bracket to be large, and the adjustment amplitude and adjustment direction of each group of photovoltaic panels are inconsistent, which is not conducive to standard construction. Therefore, when constructing the horizontal bracket, a level measuring tool will be used for measurement to ensure the horizontality of the horizontal bracket.

[0004] At present, automatic leveling instruments are used to measure horizontal supports during the construction of photovoltaic projects. However, in the Liushuquan 100,000-kilowatt photovoltaic project, due to the complex local climate and environment, the complexity and sensitivity of the automatic leveling instrument to the environment will affect the measurement accuracy and even cause the instrument to fail. Therefore, it is necessary to provide an auxiliary tool that can cope with complex climate environments and is easy to use. Utility Model Content

DETAILED DESCRIPTION

[0026] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and thus only show components related to the present invention.

[0027] Example 1

[0028] Please refer to Figure 1-3 To achieve the above purpose, the technical solution of the utility model is: a simple oil resistance plumb bob instrument, comprising:

[0029] The transparent shell 1 is a columnar structure with a closed upper end;

[0030] The base 2 is provided at the lower end of the transparent shell 1;

[0031] The plumb bob 3 is connected to a pull rope 31 , the upper end of the pull rope is connected to the upper end of the transparent shell 1 , and the lower end of the plumb bob 3 is spaced apart from the upper surface of the base 2 . The base 2 includes a positioning bottom surface 28 , which is perpendicular to the axis of the transparent shell 1 .

[0032] Specifically, in actual application, the transparent shell 1 can be made of acrylic material, and damping oil 4 is provided at the bottom of the transparent shell. The liquid level of the damping oil can fully or partially submerge the plumb bob 3. Figure 3, exemplary, the transparent shell is a rectangular columnar structure, and a reference line (not shown in the figure) is provided on one side wall of the transparent shell 1, and the reference line is extended along the axial direction. When in use, the base 2 is placed on the upper surface of the horizontal bracket, and the positioning bottom surface 28 is in contact with the horizontal reference surface of the horizontal support until the plumb bob is stationary and the pull rope 31 is straightened. At this time, the pull rope 31 is observed in the direction perpendicular to the side wall where the reference line (not shown in the figure) is provided. If the horizontal reference surface of the horizontal bracket is in a horizontal state, the pull rope 31 can coincide with the reference line. When the horizontal reference surface of the horizontal bracket is deflected, the pull rope 31 is set at a certain angle to the reference line (not shown in the figure), so that the detection purpose can be achieved. By arranging damping oil at the bottom, a damping effect can be exerted on the plumb bob, which can shorten the time it takes for the plumb bob to switch from a swinging state to a stationary state, thereby improving the detection efficiency. Figure 3 As a preferred embodiment, the liquid surface of the damping oil 4 partially submerges the plumb bob. The damping oil can be any one of hydraulic oil and diesel. At zero degrees Celsius, the viscosity coefficient is 11.0 mm 2 / s-40 mm 2 / s.

[0033] Further, as a specific embodiment, refer to Figure 1-Figure 3 Along the axis direction of the transparent shell 1, a guide rod 232 is provided on the base 2 for guidance. The upper end of the transparent shell 1 is provided with a second handle 13 connected to the guide rod 232. The upper end of the guide rod is provided with a tapered groove 231. The tapered groove 231 is coaxially arranged with the axis of the transparent shell 1. Specifically, it can be understood that the plumb bob is connected to the upper end of the transparent shell by a pull rope 31. When the plumb bob is moved, the plumb bob will swing left and right. Therefore, the plumb bob has the risk of colliding with the side wall of the transparent shell. The collision will damage the transparent shell and reduce its service life. By providing the guide rod 232 and the second handle 13, the second handle is connected to the guide rod 232, and the upper end of the guide rod is provided with a tapered groove 231. Figure 3 During normal use, the upper end of the guide rod is spaced apart from the plumb bob, which does not affect the swing of the plumb bob. After the test is completed, the second handle 13 is held and the plumb bob is lifted. At this time, the second handle can apply axial force to the guide rod 232, and the guide rod moves upward, so that the lower end of the plumb bob 3 extends into the tapered groove 231 at the upper end of the guide rod. Through this arrangement, the plumb bob 3 can be limited by the tapered groove 231, preventing the plumb bob from swinging and colliding with the side wall of the transparent shell during movement, thereby improving the service life of the transparent shell.

[0034] Furthermore, as a preferred embodiment, the lower end of the transparent shell 1 is detachably fixedly connected to the base, and the transparent shell 1 is sealed with the upper surface of the base.

[0035] Further, as a specific embodiment, refer to Figure 3-Figure 5 A cylindrical cavity 25 is provided at the upper end of the base 2, a cover plate 21 is provided at the upper end of the cylindrical cavity 25, a guide rod 232 is guided through the cover plate 21, and a movable plate 5 is provided at the lower end of the guide rod; a pull rod 22 is also guided on the cover plate 21, one end of the pull rod is connected to the movable plate 5, and the upper end is connected to the second handle 13.

[0036] Specifically, a cylindrical cavity 25 is coaxially provided at the upper end of the base, four positioning grooves 26 are provided on the upper surface of the base around the cylindrical cavity 25, and four ear plates 210 are provided on the circumference of the cover plate 21. The thickness of the ear plates is less than that of the cover plate 21, and the upper surface of the ear plates is flush with the upper surface of the cover plate 21. The bottom surface of the positioning groove 26 is provided with a threaded hole 27. When the cover plate is set at the upper end of the cylindrical cavity 25, the four ear plates can be set in the four positioning grooves 26 and locked in the threaded holes 27 by connecting bolts 211. The outer circumference of the cover plate 21 is sealed with the inner circumference of the cylindrical cavity 25, and the cover plate is connected to the transparent shell. The body is coaxially provided with a first guide channel, and the guide rod 232 is guided in the first guide channel and slidingly sealed with the first guide channel. The cover plate 21 is also provided with a second guide channel arranged parallel to the first guide channel. A pull rod 22 is guided in the second guide channel. The lower end of the pull rod is threadedly connected to the movable plate 5, and the upper end is connected to the second handle. The movable plate is threadedly connected to the end of the guide rod 232. When the second handle is pulled upward, the pull rod 22 will be pulled upward under the action of the gravity of the base and the transparent shell, thereby pushing the guide rod to move upward, so that the plumb bob enters the conical groove for positioning.

[0037] Further, as a preferred embodiment, refer to Figure 3 The upper end of the guide rod 232 is provided with a limit plate 23 that is engaged with the upper surface of the base 2. An elastic member 24 is provided between the guide rod 232 and the base. The elastic member 24 can provide elastic force for the movable plate 5 to slide away from the transparent shell. By providing the limit plate 23 and the elastic member 24, when the second handle is not under tension, the elastic force of the elastic member 24 can push the movable plate 5 downward, thereby pulling the guide rod downward so that the limit plate 23 abuts against the upper surface of the cover plate 21. Figure 3 At this time, the movable plate is spaced a certain distance from the bottom surface of the cylindrical cavity, thereby ensuring that the guide rod has sufficient return force and can fully return to its original position, thereby avoiding the situation where the guide rod cannot fully return to its original position and affects the movement of the plumb bob.

[0038] Further, as a specific implementation method, refer to Figure 3 The elastic member 24 is a compression spring, which is sleeved on the periphery of the guide rod 232, with its two ends respectively abutting against the movable plate 5 and the cover plate 21.

[0039] Furthermore, one of the limit plate 23 and the movable plate 5 is detachably fixedly connected to the guide rod 232. Specifically, in a specific embodiment, the limit plate 23 and the guide rod are integrally provided, and the guide rod 232 is threadedly connected to the movable plate 5. In this way, the guide rod is easily assembled and disassembled with the movable plate and the cover plate, and maintenance is facilitated.

[0040] Further, as a preferred embodiment, refer to Figure 3 The upper end of the transparent housing 1 is provided with an upper cover 11. The pull rods 22 include two pull rods 22 symmetrically arranged about the axis of the transparent housing. The upper ends of the two pull rods extend out of the upper cover 11, and the ends of the second handle 13 are respectively connected to the upper ends of the two pull rods 22. Specifically, the upper cover 11 is detachably fixedly connected to the upper end of the transparent housing. The upper cover 11 is provided with a third guide hole that cooperates with the guide of the pull rods 22. By providing two pull rods 22, and symmetrically arranged about the axis of the transparent housing, it is possible to ensure uniformity in the upward pulling force applied to the movable plate. As a specific embodiment, the lower ends of the pull rods 22 are threadedly connected to the movable plate.

[0041] Further, as a specific embodiment, refer to Figure 1-Figure 3 , located above the second handle, the upper cover 11 is also provided with a first handle 12. When in use, when moving the oil resistance plumb bob, first pull the second handle 13 by hand, pull the second handle upward, under the action of the plumb bob's own gravity, the compression spring moves, thereby pushing the guide rod upward, so that the plumb bob extends into the conical groove, and as it is pulled upward, the reference Figure 6 The second handle 13 contacts the first handle 12. At this time, the first handle 12 is subjected to an upward pulling force. The first handle 12 is welded or detachably fixed to the upper cover 11. The first handle limits the second handle, and the second handle no longer moves upward. Continuing to pull can lift the plumb bob.

[0042] Furthermore, as a specific implementation method, the base is made of metal material to ensure that the base has a certain gravity, thereby improving the stability of the entire device when placed on a plane and being able to cope with windy weather.

[0043] Furthermore, as a specific embodiment, the upper surface of the base 2 is provided with a first communication port 20 communicating with the interior of the transparent shell, and the lower end of the cylindrical cavity 25 is provided with a second communication port 201 , and the first communication port and the second communication port are connected.

[0044] It is understandable that, due to the fluidity of the damping oil, when the construction workers move the device by carrying the second handle and the first handle, the swinging action will cause the damping oil to swing in the transparent shell and adhere to the side wall of the transparent shell. Since the damping oil has a certain adhesion effect and the filling amount of the damping oil is certain, when in use, the damping oil adheres to the transparent shell, which will lower the damping oil level and the damping effect is poor. It is necessary to wait for the damping oil to flow down before use. Moreover, since the transparent shell is made of acrylic plate, the acrylic plate will cause certain damage to the shell after contact with the oil, reducing the service life of the transparent shell and reducing the transparency. The reduced transparency affects observation. The present application provides a first connecting port 20 and a second connecting port 201 that are connected, and the outer peripheral surface of the movable plate is slidably sealed with the inner peripheral surface of the cylindrical cavity. A connecting flow channel 250 connected to the atmosphere is provided at the upper end of the cylindrical cavity, so that the movable plate can achieve the effect of a piston. Figure 3 In the state shown, the elastic force of the elastic member 24 squeezes the damping oil into the upper transparent housing, providing a damping effect. When the handle is moved, the movable plate is pulled upward, generating negative pressure below the cylindrical cavity, thereby drawing the damping oil from above into the cylindrical cavity and preventing it from sloshing. When transporting the plumb bob, a strap can be used to tie the first and second handles together, confining the damping oil within the cylindrical cavity and preventing it from sloshing within the transparent housing.

[0045] Example 2

[0046] This application provides a simple oil resistance plumb bob instrument, which is different from the first embodiment in that Figure 7 , the upper surface of the movable plate 5 is provided with a connecting sleeve 51 which is threadedly connected to the pull rod 22, and the other components are consistent with the solution in the first embodiment. Through this arrangement, when moving the plumb bob, the hand holds the second handle and the first handle at the same time, applies a gripping force to the first handle and the second handle, and moves the second handle close to the first handle. When the connecting sleeve 51 abuts against the cover plate 21, the second handle no longer moves upward. At this time, the damping oil can be sucked into the bottom of the cylindrical cavity 25, and the plumb bob enters the conical groove. The state at this time is as follows Figure 7 As shown, at this time, the first handle and the second handle are spaced a certain distance apart, which is conducive to applying a gripping force, and then pulling upward to move the plumb bob. Through this setting, the gripping force can resist the elastic force of the elastic member 24, accelerate the speed of the damping oil entering the cylindrical cavity, and after the plumb bob enters the conical groove, pull the plumb bob to ensure that the plumb bob can effectively enter the conical groove for positioning.

[0047] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
