Description

Technical Field

[0001] The utility model relates to the technical field of speed measuring gun brackets, and more specifically, to a portable radar speed measuring gun bracket. Background Art

[0002] The handheld radio wave current meter (SVR-VP), commonly known as the "radar speed measuring gun", is an imported device for the national key 948 project. It is equipped with a vertical angle sensor for automatic vertical angle correction and manual horizontal angle input. It is mainly used for field surveys, emergency measurements such as floods, dam breaks, breaches, and debris flows, and is especially suitable for measuring flood peaks during the flood season.

[0003] It is found in the actual use process that the automatic vertical angle correction and cosine error correction of the radar speed measuring gun are not perfect. Affected by terrain or human operation, when the horizontal deviation angle between the radar probe and the target moving direction is large, it will exceed the correction range of the radar speed measuring gun. For example, in special terrains where people cannot reach, when the radar speed measuring gun is lifted over for measurement, the horizontal deviation angle often exceeds 10°, and often there will be an uncorrectable cosine error (cosine effect), resulting in a large measurement error of the radar speed measuring gun. There is an urgent need in the prior art for a bracket that can fixedly install the radar speed measuring gun on the guardrail of the horizontal measurement platform and can adjust the horizontal and angle of the installed radar speed measuring gun. Summary of the Utility Model

[0004] The utility model aims to overcome the above-mentioned deficiencies and provides a portable radar speed measuring gun bracket, which can facilitate the installation of the bracket and can adjust the vertical angle and horizontal deviation angle of the installed radar speed measuring gun.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Specific embodiments:

[0026] Such as Figures 1-5As shown, a portable radar speed gun bracket includes an angle adjustment mechanism 1, which includes a first bracket 11 and a second bracket 12. The cross-sections of the first bracket 11 and the second bracket 12 are both in the shape of a U-shaped bracket. The openings of the first bracket 11 and the second bracket 12 are opposite to each other and the second bracket 12 is located in the opening of the first bracket 11. The first bracket 11 and the second bracket 12 are rotatably connected through a pin shaft 2; the lower end surface of the first bracket 11 is fixedly connected to a horizontal adjustment platform 3, and the horizontal adjustment platform 3 is a VELEDGE tripod horizontal adjustment pan-tilt platform. The lower end of the horizontal adjustment platform 3 is provided with a first fixing mechanism 4, and the first fixing mechanism 4 is used to install the bracket on a horizontal test platform guardrail (such as a bridge guardrail); the second bracket 12 is provided with a notch 121, and the notch 121 is used to insert the grip of the radar speed gun 5, and the radar speed gun 5 is an SVR The 3D portable radar speed gun has a second fixing mechanism 6 for fixing the radar speed gun 5 on the second bracket 12. The second fixing mechanism 6 clamps the integrated guide rail 51 on the radar speed gun 5. The first fixing mechanism 4 facilitates the installation of the bracket and the radar speed gun 5 on the guardrail of the horizontal test platform, and the level of the radar speed gun 5 is adjusted through the horizontal adjustment platform 3, and the angle of the radar speed gun 5 is adjusted through the angle adjustment mechanism 1.

[0027] like Figures 1-5 As shown, the angle adjustment mechanism 1 also includes a through slot 13 opened on the side wall of the first bracket 11. The two side walls of the first bracket 11 are both provided with a through slot 13 and the two through slots 13 are symmetrical. The through slot 13 is arc-shaped and the center of the circle in which it is located is located on the center line of the pin shaft 2. A second threaded rod 14 slides in the through slot 13. One end of the second threaded rod 14 close to the second bracket 12 passes through and is threadedly connected to the second bracket 12, and the other end is fixedly connected to a second knob 15. The second knob 15 is made of rubber material. The side of the second knob 15 close to the first bracket 11 is set to a rough surface (not shown in the figure). The body size of the second knob 15 is larger than the opening size of the through slot 13, and a scale 16 is set on the edge of the through slot 13. The level of the angle adjustment mechanism 1 can be adjusted through the horizontal adjustment platform 3. Since the radar speed gun 5 is installed on the angle adjustment mechanism 1, the level adjustment of the radar speed gun 5 is completed; the second knob 15 is turned to make it away from the first bracket 11, and the second knob 15 is separated from the first bracket 11. The second bracket 12 can be rotated relative to the first bracket 11 by turning the second knob 15, so that the angle of the second bracket 12 is adjusted with reference to the scale 16, and then the angle of the radar speed gun 5 is adjusted. After the adjustment is completed, the second knob 15 is turned to make it fit the side wall of the first bracket 11. Under the action of friction, the second bracket 12 will not rotate relative to the first bracket 11, thereby completing the adjustment of the angle of the radar speed gun 5, adjusting the angle and level of the radar speed gun, avoiding a certain cosine angle error and lateral level error, and making the measurement more accurate.

[0028] likeFigures 1-5 As shown, the first fixing mechanism 4 includes a clamping plate 41. The cross-section of the clamping plate 41 is U-shaped. A first threaded rod 42 penetrates and is threadedly connected to the side wall of the clamping plate 41. One side of the first threaded rod 42 located inside the opening of the clamping plate 41 is fixedly connected with a pressing block 43. The pressing block 43 is made of rubber material and is provided with a rough surface (not shown in the figure). The other end of the first threaded rod 42 is fixedly connected with a first knob 44. When installing the bracket, the clamping plate 41 is clamped on the guardrail of the horizontal test platform (such as the bridge guardrail), and the first knob 44 is rotated to make the first threaded rod 42 rotate. The pressing block 43 approaches and abuts against the guardrail, so that the first fixing mechanism 4 fixes the bracket on the guardrail. Then, the radar speed gun 5 is installed, and then it is adjusted through the angle adjustment mechanism 1 and the horizontal adjustment table 3.

[0029] As Figures 1-5 As shown, the second fixing mechanism 6 includes a vertical rod 61 fixedly connected to the second bracket 12. The free end of the vertical rod 61 is fixedly connected with a first clamping member 62. A second clamping member 63 is arranged on one side of the first clamping member 62. A plurality of positioning rods 64 are fixedly connected to the side of the second clamping member 63 close to the first clamping member 62. The positioning rods 64 slide on the first clamping member 62. A third threaded rod 65 penetrates and is threadedly connected to the second clamping member 63. One end of the third threaded rod 65 close to the first clamping member 62 is rotatably connected to the first clamping member 62 through a bearing seat (not shown in the figure). The bearing seat is embedded in the first clamping member 62 without affecting the fitting of the first clamping member 62 and the second clamping member 63. The opening after the first clamping member 62 and the second clamping member 63 are fitted is adapted to the integrated guide rail 51. While inserting the handle of the radar speed gun 5 into the notch 121, the integrated guide rail 51 is inserted into the first clamping member 62, and then the third threaded rod 65 is rotated to make the second clamping member 63 move towards the first clamping member 62 under the restriction of the positioning rods 64 until they fit, so that the first clamping member 62 and the second clamping member 63 clamp and fix the radar speed gun 5. When disassembling the radar speed gun 5, only need to rotate the third threaded rod 65 in the reverse direction to make the second clamping member 63 move away from the first clamping member 62.

[0030] As Figures 1-5 As shown, nuts are provided at the threaded connection between the clamping plate 41 and the first threaded rod 42 and at the threaded connection between the second bracket 12 and the second threaded rod 14 for threaded connection.

[0031] The working principle of a portable radar speed gun bracket in the present embodiment is as follows: when in use, by clamping the card plate 41 on the horizontal test platform guardrail (such as the guardrail on the bridge), turning the first knob 44 to rotate the first threaded rod 42, and the abutment block 43 approaches the guardrail and abuts against it, so that the first fixing mechanism 4 fixes the bracket on the guardrail, and then the radar speed gun 5 is installed and fixed by the second fixing mechanism 6, and the level of the radar speed gun 5 is adjusted by the horizontal adjustment platform 3, and the second knob 15 is turned to make it away from the first bracket 11, and the second knob 15 is disengaged from the first bracket 11, and the second bracket 12 can be rotated relative to the first bracket 11 by turning the second knob 15, so that the angle of the second bracket 12 is adjusted with reference to the scale 16, and then the angle of the radar speed gun 5 is adjusted. After the adjustment is completed, the second knob 15 is turned to make it fit the side wall of the first bracket 11. Under the action of friction, the second bracket 12 will not rotate relative to the first bracket 11, thereby completing the adjustment of the angle of the radar speed gun 5. After use, the radar speed gun 5 and the bracket are removed, and the bracket is convenient for disassembly and carrying.
