Description

Technical Field

[0001] The utility model belongs to the technical field of sunshine angle detection tools, and in particular relates to a sunshine angle detection device. Background Art

[0002] The sunshine angle, also known as the solar altitude angle, is the angle between the sun's rays and the horizon. The sunshine angle is of great significance to energy utilization, architectural design, agriculture and other fields. For example, in terms of energy utilization, the sunshine angle plays an important role in the design and optimization of solar energy systems, so it is necessary to measure the sunshine angle.

[0003] A Chinese patent with publication number CN208383119U discloses a solar altitude and azimuth measuring instrument, which includes a base, an azimuth dial, a vertical pole and an altitude auxiliary measuring piece. The above scheme uses a manually rotating shadow altitude pointer to coincide the center line of the pointer with the shadow of the vertical pole, reads the shadow height from the scale lines on both sides of the center line, and then calculates the solar altitude angle through trigonometric functions.

[0004] When the above solution is used, in order to measure the sunshine angle (ie, the solar altitude angle), it is necessary to use trigonometric functions for calculation, which is relatively complicated and cannot intuitively display the sunshine angle. Utility Model Content

[0005] The utility model aims to provide a sunlight angle detection device to solve the problems of the above-mentioned solution that the operation is relatively complicated and the sunlight angle cannot be displayed intuitively.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A sunshine angle detection device comprises a base, an azimuth dial, a turntable and a pointer, wherein a compass is fixedly arranged on the top of the base, a groove is arranged on the top of the base at the outer periphery of the compass, the azimuth dial is rotatably arranged in the groove along the axial direction of the compass, a first scale is arranged on the top of the azimuth dial along the circumferential direction of the compass, the turntable is rotatably sleeved on the azimuth dial, an altitude dial is vertically arranged on the top of the turntable, the altitude dial is coplanar with the axis of the turntable, the altitude dial is arranged in a semi-annular shape, a second scale is arranged on the side wall of the altitude dial along its annular axis, the pointer has a sliding groove running through the left and right, the sliding groove is slidably sleeved on the altitude dial, and the upper and lower side end walls of the sliding groove are respectively slidably abutted against the upper and lower side end walls of the altitude dial, the front wall of the pointer is provided with a through groove matched with the second scale, and the upper and lower ends of the front wall of the pointer are also perpendicular to the pointer and fixed with a light-transmitting plate and a projection screen parallel to each other.

[0008] The principle and effect of this technical solution:

[0009] Place the device at the location to be measured, rotate the azimuth dial to align it with the direction indicated by the compass, rotate the altitude dial until its projection is minimum, and the reading of the first scale aligned with the projection is the azimuth of the location to be measured. Then slide the pointer along the altitude dial to rotate it along the axis of the altitude dial until the center of the projection of the light-transmitting plate coincides with the center of the projection screen. At this time, the reading of the second scale aligned with the through slot is the sunshine angle of the point to be measured at this time.

[0010] Through the above arrangement, while measuring the azimuth of the place to be measured, the pointer is used to rotate along the altitude angle dial, and the center of the projection of the light-transmitting plate is made to coincide with the center of the projection screen. The second scale aligned with the through slot is used to intuitively display the sunshine angle of the point to be measured at this time, without the need for additional calculations, thereby simplifying the operation steps and improving the detection efficiency.

[0011] In the utility model, a level adjustment mechanism is arranged at the bottom of the base, and a leveler is fixedly arranged at the top of the side wall of the base.

[0012] In the utility model, the horizontal adjustment mechanism includes a screw rod and a support plate, and the screw rod and the support plate are both provided in number of three. The three screw rods are threadedly inserted into the bottom of the base at intervals along the circumference of the compass, a ball pin is fixedly provided at the bottom of the screw rod, and a ball seat is fixedly provided at the top of the support plate, and the ball seat is rotatably sleeved on the corresponding ball pin.

[0013] The principle and effect of this technical solution:

[0014] Before the test begins, the three screw rods are rotated to change the length of each screw rod extending out of the bottom of the base, and the base is adjusted to a horizontal state by a leveler.

[0015] Through the above settings, the device can be adjusted to a horizontal state, thereby improving the accuracy of the detection results.

[0016] In the utility model, a through hole is opened on the rear side wall of the pointer, a limit rod is slidably inserted into the through hole, a tension spring is sleeved on the outer circumference of the limit rod at the rear side of the pointer, and the two ends of the tension spring are respectively connected to the rear end of the limit rod and the rear side wall of the pointer.

[0017] The principle and effect of this technical solution:

[0018] In the initial state, the tension spring is in an extended state and has a certain elastic force, thereby pushing one end of the limit rod through the through hole and abutting against the side wall of the altitude angle dial. When an external force moves the pointer, the external force is greater than the friction between the limit rod and the altitude angle dial, and the pointer can be moved. When the center of the projection of the light-transmitting plate coincides with the center of the projection screen and the external force is removed, the gravity of the pointer is less than the friction between the limit rod and the altitude angle dial, and the pointer is fixed on the altitude angle dial.

[0019] Through the above arrangement, the pointer can stay on the surface of the altitude angle dial in an inclined state, making it convenient for the staff to read and record the data.

[0020] In the utility model, the pointer is connected to the altitude angle dial by magnetic attraction.

[0021] The principle and effect of this technical solution:

[0022] In the initial state, the pointer and the altitude angle dial are connected by magnetism. At this time, the magnetic force is greater than the friction between the two, and the pointer is fixed on the altitude angle dial. When an external force moves the pointer, the external force is greater than the friction between the two, and the pointer can be moved.

[0023] Through the above arrangement, the pointer can stay on the surface of the altitude angle dial in an inclined state, making it convenient for the staff to read and record the data.

[0024] In the utility model, a limit plate is fixedly arranged on the outer periphery of the bottom of the azimuth angle scale plate, and a first screw hole is opened on the side wall of the groove within the height range of the limit plate. A first bolt is threaded through the inner thread of the first screw hole, and one end of the first bolt extends into the groove and can press against the side wall of the limit plate.

[0025] The principle and effect of this technical solution:

[0026] In the initial state, the first bolt does not contact the side wall of the limiting plate. At this time, the azimuth dial can be rotated to an appropriate position, and then the first bolt is rotated so that one end of the first bolt extends into the groove and presses against the side wall of the limiting plate.

[0027] Through the above arrangement, the azimuth angle scale can be fixed after being rotated to an appropriate position, thereby preventing the azimuth angle scale from continuing to rotate relative to the base during the rotation of the turntable, thereby improving the practicality of the utility model.

[0028] In the utility model, a second screw hole is opened on the side wall of the groove within the height range of the turntable, and a second bolt is threaded through the second screw hole. One end of the second bolt extends into the groove and can press against the side wall of the turntable.

[0029] The principle and effect of this technical solution:

[0030] In the initial state, the second bolt does not contact the side wall of the turntable. At this time, the turntable can be rotated to an appropriate position, and then the second bolt is rotated so that one end of the second bolt extends into the groove and presses against the side wall of the turntable.

[0031] Through the above arrangement, the turntable can be fixed after it rotates to an appropriate position, thereby preventing the turntable from continuing to rotate relative to the azimuth angle scale during the movement of the pointer, thereby improving the practicality of the utility model.
