Description

Technical Field

[0001] This utility model relates to a Doppler mounting bracket, and more particularly to an adjustable Doppler mounting bracket. Background Technology

[0002] Typically, water flow rate is measured by measuring the cross-sectional area of ​​the channel, using a testing instrument to measure the water flow velocity, and then calculating the water volume.

[0003] However, for narrow waterways or water tanks against walls (e.g., well tanks), a combination of a fixed pole and ropes is generally used. Specifically, the testing instrument is mounted on a steel fixed pole, and the other end of the pole is secured with several ropes. A person holds the ropes or supports the fixed pole, placing it in the waterway / tank. Its disadvantages are:

[0004] ① If the rope is not tied securely, there is a risk of losing the fixing pole or equipment;

[0005] ② When encountering large flow rates or cross-sectional areas, it is difficult to perform stable measurements manually, which affects the stability and accuracy of the measurement work and leads to larger measurement errors. Summary of the Invention

[0028] As shown in the figure, this utility model is an adjustable Doppler mounting bracket, including a horizontal bar part I and a vertical bar part III, which are mounted through a movable adjustment part II.

[0029] The crossbar section I includes a crossbar 4, an L-shaped bracket 17, and a crossbar connecting block 7. To prevent rotation, the crossbar is frame-shaped and hollow inside, with equally spaced crossbar mounting holes 8 along its length. One end of the crossbar 4 is integrally mounted (e.g., welded) to the L-shaped bracket 17, and the other end is fitted with the crossbar connecting block 7. The L-shaped bracket 17 has bracket mounting holes 13, and the crossbar connecting block 7 has connecting block mounting holes 12. During installation, they are fixed by matching bolts. Both the L-shaped bracket 17 and the crossbar connecting block 7 serve to support the crossbar 4.

[0030] The adjustable part I includes a horizontal slider 5, a fixing block 18, and a vertical slider 19. The horizontal slider 5 is fixedly welded to the top of the fixing block 18. The shape of the horizontal slider 5 is the same as that of the horizontal bar 4, and its arrangement direction is the same as that of the horizontal bar. The hollow part of the horizontal slider 5 is a horizontal bar square groove 15. The outer edge of the horizontal bar 4 and the inner edge of the horizontal slider 5 are fitted together. The horizontal slider 5 is provided with two horizontal slider mounting holes 9. During installation, these mounting holes correspond to two of the horizontal bar mounting holes 8 on the horizontal bar 4, and are fixed with matching bolts. The vertical slider 19 is fixedly welded to one side of the fixing block 18. The vertical slider 19 is arranged in the same direction as the vertical bar 6 and has the same shape. In this invention, the vertical slider 19 and the vertical bar 6 are set with a triangular cross section to facilitate angle adjustment. The hollow part of the longitudinal rod slider 19 is the longitudinal rod triangular groove 16. The outer edge of the longitudinal rod 6 and the inner edge of the longitudinal rod slider 19 are matched and fitted together. The longitudinal rod slider 19 is provided with longitudinal rod slider threaded holes 11 arranged at equal intervals. During installation, the longitudinal rod slider threaded holes 11 correspond to several longitudinal rod mounting holes 10 on the longitudinal rod 6 and are matched and fixed with bolts.

[0031] The longitudinal rod section III consists of longitudinal rods 6, which have a triangular cross-section. Along the length of the longitudinal rod 6, the upper half of its three faces are provided with longitudinal rod mounting holes 10 arranged at equal intervals. On the same horizontal plane, the longitudinal rod mounting holes 10 on the three faces correspond to each other. The lower half of the longitudinal rod 6 is provided with several slots 20 arranged at equal intervals. The slots are rectangular and are arranged at equal intervals along the length of the longitudinal rod 6 on one face of the longitudinal rod 6. When the longitudinal rod is submerged in water, water is drained through the slots 20, reducing the resistance of the water to the longitudinal rod.

[0032] The bracket is installed at the water tank 1, with the two ends of the crossbar 4 positioned on both sides of the water tank edge, and the bottom of the vertical bar 6 positioned inside the water tank. A Doppler mounting platform 14 is vertically mounted at the bottom of the vertical bar 6 for mounting the Doppler sensor 2.

[0033] Installation process:

[0034] ① Fix the crossbar connecting block 7 to the edge of one side of the water tank 1 with expansion screws.

[0035] ② Mount the longitudinal rod slider 19 onto the longitudinal rod 6, and install the longitudinal rod 6 into the longitudinal rod mounting hole 10 by tightening the screw in the longitudinal rod slider screw hole 11.

[0036] ③ Install the Doppler sensor 2 on the Doppler mounting platform 14, and extend the composite wire 3 behind the Doppler sensor 2 from the slot at the bottom of the longitudinal rod, and lead it out along the length of the longitudinal rod to the top of the longitudinal rod 6 for easy wiring.

[0037] ④ Fit the transverse square groove 15 of the crossbar slider 5 into the crossbar 4, and use long screws to fix the crossbar slider mounting hole 9 and the crossbar mounting hole 8 together to complete the installation of the crossbar.

[0038] ⑤ Pass the other end of the crossbar 4 through the crossbar bracket connecting block 7, and finally fix the bracket fixing hole 13 to the other side of the sink with expansion screws. The overall installation is complete.

[0039] If the water depth is not suitable, remove the screw on the sliding block threaded hole to adjust the water depth of the vertical rod or adjust the angle of the vertical rod, for example, to suspend the detector off the ground to prevent underwater mud and sand from obstructing the detection.

[0040] If the horizontal position is not suitable, remove the long screw on the crossbar mounting hole 8, adjust the position, and then reinstall it.

[0041] If the sink is narrow or too close to the wall, the angle of the triangular groove of the vertical bar can be rotated to set the horizontal bar at an angle, so that the vertical bar and the horizontal bar are at a certain angle to achieve the effect of the horizontal bar being installed at an angle, which is convenient for measurement.

[0042] This invention relates to an adjustable Doppler mounting bracket. The horizontal and vertical rods are installed via adjustable mechanisms. The horizontal rod is fitted into a horizontal rod slider, and the vertical rod into a vertical rod slider. During installation, both ends of the horizontal rod are fixed to the edges of the water tank / channel. The horizontal position of the ends of the horizontal rod is adjusted according to the width of the water tank / channel, and the position of the vertical rod on the vertical rod slider is adjusted according to the depth. The Doppler sensor is fixed on the Doppler mounting platform. This design ensures the bracket is relatively stable, preventing equipment loss and facilitating stable and accurate measurements with minimal error. This invention features a simple structure, is easy to install, and is particularly suitable for measuring flow velocity in narrow waterways.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
