DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] Example 1, reference Figure 1 to Figure 6 , which is the first embodiment of the utility model, and provides a device for measuring the installation angle of a concentrated solar cell photovoltaic panel. By using gravity, the angle between the vertical direction of the pendulum 201 and the scale of the shell is measured after the pendulum 201 stops swinging, so as to directly read the inclination angle of the fitting surface of the base 104. The device comprises a shell mechanism 100, which comprises a square first side cover 101 and a second side cover 102, and a circular middle frame 103 is sealed and crimped between the first side cover 101 and the second side cover 102. A short tube 101a is provided in the middle of the first side cover 101, and a collar 102a is provided on the second side cover 102 to be sealed and sleeved with the short tube 101a; an angle indicating mechanism 200 comprises a first side cover 101 and a second side cover 102a, and a second side cover 102a is sleeved and sleeved with the first side cover 101a; ... The pendulum 201 between the side cover 101, the second side cover 102 and the middle frame 103, the top end of the pendulum 201 is sleeved with a thin-walled bearing 202, and the inner ring of the thin-walled bearing 202 is sleeved with the outer wall of the short tube 101a, the bottom protrusion of the pendulum 201 is provided with a counterweight portion 201a, and the bottom surface of the counterweight portion 201a is provided with an arc edge 201b, and the arc axis of the arc edge 201b is coaxial with the arc axis of the middle frame 103 and the thin-walled bearing 202, the inner wall of the middle frame 103 is parallel to its axial direction and a spoiler strip 103a is provided, and a gap is left between the arc edge 201b and the spoiler strip 103a, and the first side cover 101, the second side cover 102 and the middle frame 103 are filled with damping fluid.

[0028] Specifically, the facades of the first side cover 101 and the second side cover 102 are both provided with first scale lines 101c, and the first scale lines 101c are distributed in a circular array with respect to the middle frame 103. The counterweight portion 201a of the pendulum 201 is vertically provided with second scale lines 201c on both sides. The first side cover 101 and the second side cover 102 are made of transparent materials. Screws 105 and nuts 106 are locked between the first side cover 101 and the second side cover 102, and the screws 105 and nuts 106 are distributed on the first side cover 101 and the second side cover 102. The four corners of the side cover 101 and the second side cover 102, the screws 105 and the nuts 106 are located on the outside of the middle frame 103, the base 104 is clamped between the bottom of the first side cover 101 and the second side cover 102, and the first side cover 101 and the second side cover 102 are perpendicular to the bottom surface of the base 104, the top of the base 104 is provided with an arc groove 104a, and the arc groove 104a is matched with the outer wall of the middle frame 103, and the screws 105 pass through the base 104 and are located at both ends of the arc groove 104a.

[0029] The working method and advantages of the device are further explained in combination with the prior art: the simple angle measuring tool on the market has a circle of scale lines printed on its shell, a swivel is rotatably sleeved inside the scale lines, and a level bubble 300 is radially assembled inside the swivel. When measuring, it is necessary to fit the shell detection surface to the detected surface, and then manually adjust the swivel to the level of the level bubble 300. Use the level bubble 300 to make the scale on the swivel at a horizontal or vertical angle, and then read the angle between the conversion scale and the shell scale to obtain the inclination angle of the measured surface. The inconvenience is that the swivel needs to be calibrated once with the level bubble 300 for each measurement.

[0030] The difference between the present invention and the prior art is that the device mainly provides an angle measurement tool that can read directly without calibration, wherein the pendulum 201 is compared with the rotating ring part of the prior product, and the bottom surface of the base 104 of the device is attached to the surface of the photovoltaic panel, and the pendulum 201 is quickly swung down to the second scale line 201c to the vertical angle through gravity and the rotation support of the thin-walled bearing 202, and the angle indicated by the second scale line 201c pointing to the first scale line 101c on the housing mechanism 100 is read. Of course, in order to realize the above-mentioned convenient angle reading function, the following technical details need to be solved:

[0031] First, in order to make the pendulum 201 swing flexibly and ensure that the second scale line 201c is at a vertical angle each time the pendulum 201 stops, the device is equipped with a thin-walled bearing 202 for the pendulum 201. However, there are problems such as the pendulum 201 swinging repeatedly and the long waiting time for the pendulum 201 to stop. Therefore, the device adds liquid damping to the pendulum 201. It is required that the liquid damping should not affect the flexible swinging of the pendulum 201, and at the same time, it is also required to consume the energy of the pendulum 201 during the oscillation, so that the pendulum 201 can stop quickly and accurately. Please refer to Example 2 for details.

[0032] Secondly, when the device is in use, the pendulum 201 needs to be in a vertical plane and work. When the shell mechanism 100 tilts to the side, it will cause deviations in the measurement results. Therefore, the device improves the structural utilization of the shell mechanism 100 and provides an installation interface for the level bubble 300. The level bubble 300 can be selectively installed to expand the function. Please refer to Example 3 for details.

[0033] In summary, the device uses gravity and the rotation support of the thin-walled bearing 202 to allow the pendulum 201 to quickly swing down to the second scale line 201c to a vertical angle, replacing the traditional manual calibration steps and simplifying the operation process.

[0034] Example 2, reference Figure 2 , Figure 5 and Figure 6 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a deflection indicating mechanism 200 of a mounting angle measuring device for a concentrated solar cell photovoltaic panel, which solves the problems of the waiting time and the accuracy of the pendulum 201 stopping. It includes: the spoiler strip 103a is arranged radially toward the middle frame 103, and the cross-sectional profile of the spoiler strip 103a is Y-shaped, the spoiler strip 103a is distributed in an annular array with respect to the middle frame 103, the distance between the two ends of the arc edge 201b is greater than the distance between two adjacent spoiler strips 103a, and the outer wall of the pendulum 201 outside the counterweight portion 201a is arranged in an arc, and is sleeved with a clip 203, and The clip 203 is arranged in a C shape, and the gap between the outer arc wall of the clip 203 and the spoiler strip 103a is larger than the gap between the arc edge 201b and the spoiler strip 103a, the curvature of the counterweight portion 201a is less than 100 degrees, and the curvature of the inner arc wall of the clip 203 is greater than one hundred and twenty degrees. A step 101b is arranged at the connection between the outer wall of the short tube 101a and the first side cover 101, and at the connection between the outer wall of the ring 102a and the second side cover 102, and the step 101b is in conflict with the inner ring end face of the thin-walled bearing 202. The pendulum 201 is assembled with and only contacts the outer ring of the thin-walled bearing 202, and the pendulum 201 and the thin-walled bearing 202 have an interference fit.

[0035] The damping fluid is a mixture of industrial pure water, anti-rust powder, viscosity regulator, antifreeze and anti-boiling agent. The antifreeze and anti-boiling agent are mainly for normal use in cold or hot areas. The viscosity regulator is used to adjust the fluidity of the damping fluid and slow down the swing speed of the pendulum 201 through flow resistance, thereby reducing the swing waiting time of the pendulum 201. The anti-rust powder is mainly used to prevent rust on the thin-walled bearing 202.

[0036] However, it is obvious that there is a limit to reducing the fluidity by only increasing the viscosity of the damping fluid. When the fluidity of the damping fluid is too low, the pendulum 201 will stick and cannot be accurately stopped at a vertical angle. Therefore, the viscosity of the damping fluid is slightly higher than that of industrial pure water, which plays an auxiliary role. The spoiler strip 103a in the middle frame 103 and the clip 203 on the top of the pendulum 201 also need to work together to achieve the purpose of absorbing energy when the pendulum 201 swings.

[0037] When the pendulum 201 repeatedly swings, the raised counterweight 201a pushes the damping fluid to flow along a circular path. It requires energy to push the damping fluid to flow, so it consumes part of the swing energy of the pendulum 201. In the fluid, when the frontal surface is concave, it can provide higher flow resistance than the flat surface and convex surface. When the damping fluid is pushed to flow along the inner wall of the middle frame 103, the Y-shaped spoiler strip 103a forms strip-shaped notches on both sides thereof, which increases the flow resistance of the damping fluid. The resistance also depends on the flow speed of the damping fluid. That is to say, when the swing amplitude of the pendulum 201 is small, the damping fluid will flow along the inner wall of the middle frame 103. When the swing amplitude of the pendulum 201 is relatively large, the Y-shaped spoiler strip 103a can produce a relatively large flow resistance to the damping fluid, so that the swing amplitude of the pendulum 201 is rapidly reduced. When the swing amplitude of the pendulum 201 is relatively small, the flow resistance of the damping fluid by the Y-shaped spoiler strip 103a will also be reduced. The smaller the swing amplitude of the pendulum 201, the smaller the resistance it encounters. Therefore, it will not affect the final precise stopping of the pendulum 201 at a vertical angle. When the swing amplitude of the pendulum 201 is extremely small, the resistance required for its stopping is also reduced to a very low level. Therefore, when the Y-shaped spoiler strip 103a fails, the viscosity of the damping fluid is the main acting condition.

[0038] In order for the Y-shaped spoiler strip 103a to fully play its role, more damping fluid needs to flow around the Y-shaped spoiler strip 103a. Therefore, a lightweight clip 203 is clamped on the top of the pendulum 201 to fill the larger gap between the thin-walled part of the pendulum 201 and the Y-shaped spoiler strip 103a, so as to reduce the flow cross-section between the pendulum 201 and the spoiler strip 103a. However, it should be noted that the gap between the outer wall of the clip 203 and the Y-shaped spoiler strip 103a cannot be too small to avoid affecting the reaction speed of the pendulum 201.

[0039] refer to Figure 5 It should be noted that the above functions are all achieved by applying flow resistance to the damping fluid and thus affecting the pendulum 201, and the premise is that the counterweight portion 201a of the pendulum 201 needs to effectively push the damping fluid when swinging, so the outer wall of the pendulum 201 is designed with an arc edge 201b, the length of the arc edge 201b at least covers a pair of adjacent spoiler strips 103a, and the gap between the arc edge 201b and the spoiler strip 103a is small enough.

[0040] The rest of the structure is the same as that of Example 1.

[0041] In summary, the deflection angle indicating mechanism 200 of the device, by combining the preparation of damping fluid, the shell structure design and the pendulum 201 structure design, realizes the rapid and accurate stopping of the pendulum 201 at a vertical angle under the action of gravity, thereby greatly improving the working efficiency of the device.

[0042] Example 3, reference Figure 1 , Figure 2 and Figure 7 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides an application simulation of an installation angle measuring device for a concentrated solar cell photovoltaic panel, which further expands the function of the device. It includes: a ring 102a is sleeved on the inside of the short tube 101a, and the first side cover 101 is inserted with a level bubble 300 through the short tube 101a. The level bubble 300 is interference fit with the short tube 101a, and one end of the level bubble 300 is in conflict with the ring 102a.

[0043] The area where the first side panel is located inside the short tube 101a and the area where the second side panel is located inside the ring 102a do not participate in the automatic angle indication function and other functions of the device such as installation, fixation, and support. Therefore, in order to further improve the structural utilization rate of the device, the first side panel and the second side panel are adaptively opened at the short tube 101a and the ring 102a to obtain an interface for plugging in the level bubble 300. After plugging in the level bubble 300, under some special usage conditions, such as measuring components that do not have planar conditions such as round tubes in photovoltaic brackets, the pendulum 201 of the device can be calibrated to the vertical working surface by observing the level bubble 300, so that the detection result is more accurate.

[0044] The rest of the structure is the same as that of Example 2.

[0045] In summary, the device not only has the effect of fast angle reading, but also provides functional expansion.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
