[0002] The lead weight current meter is a core device used in hydrological surveys to measure river flow velocity. It consists of a lead weight and a flow velocity sensor, and is suspended in the water via a cable system to measure flow velocity at a fixed point.

[0003] In existing technologies, when measuring river flow velocity, a steel cable is used to suspend the cable car below the hydrological cableway, and the weight of the lead weight is used to resist the impact of the rapid flow, achieving precise vertical positioning. However, in actual applications, the lead weight and the current meter installed below it may not be initially parallel to the water flow direction. The error caused by the flow direction deviation leads to certain deviations in the data. Therefore, we propose a directional device suitable for cableway radar wave flow measurement.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] This application provides a directional device suitable for radar wave flow measurement in cableways. It solves the problem that in practical applications, the initial state of the lead weight body 1 and the current meter 6 installed below it may not be parallel to the water flow direction, leading to errors caused by the flow direction deviation and resulting in data discrepancies. The device achieves this by installing the guide rod 7 at the tail end of the lead weight body 1. This is achieved by inserting the mounting bracket 711 into the corresponding rear connecting bracket 3, and then inserting the positioning bolt 712 into the rear connecting bracket 3 and the mounting bracket 711. The guide rod 7 is then installed with the rear connecting bracket 3. The guide rod 7 is adjusted to a suitable angle, and then the positioning nut 715 is rotated to compress the spring 714. This causes the spring 714 to push the washer 713 against the mounting bracket 711, thus clamping the rear connecting bracket 3 and ensuring the connection between the guide rod 7 and the rear connecting bracket 3. This fixes the guide rod 7 at a suitable angle, adjusts the axis of the current meter 6 to be parallel to the water flow direction, and reduces errors caused by the flow direction deviation.

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] This utility model discloses a directional device suitable for radar wave flow measurement in cableways.

[0033] According to the appendix Figure 1-6 As shown, the device includes a lead weight body 1, a connecting unit 2 at the front end of the lead weight body 1, a radar wave tester 5 mounted above the connecting unit 2, a comparison frame 4 mounted below the connecting unit 2, a mounting rod 42 fixedly connected to the bottom end face of the comparison frame 4, a flow meter 6 mounted on the outer peripheral wall of the mounting rod 42, a rear connecting frame 3 at the rear end of the lead weight body 1, a line-fixing rod 7 mounted at the rear end of the rear connecting frame 3, and a mounting unit 71 at one end of the line-fixing rod 7. The mounting unit 71 includes:

[0034] Mounting bracket 711 is fixedly connected to the end of the guide rod 7, and mounting bracket 711 is inserted into the rear connecting bracket 3;

[0035] Positioning bolt 712 is inserted into the inner wall of mounting bracket 711 and rear connecting bracket 3;

[0036] Washer 713 is sleeved on the outer peripheral wall of positioning bolt 712, and washer 713 is in contact with mounting bracket 711;

[0037] A spring 714 is sleeved on the outer peripheral wall of the positioning bolt 712, and one side of the spring 714 is in contact with the washer 713.

[0038] The outer peripheral wall of the positioning bolt 712 is threaded with a positioning nut 715, which is in contact with the spring 714.

[0039] When it is necessary to install the line-fixing rod 7 at the tail end of the lead fish body 1, the mounting bracket 711 is inserted into the corresponding rear connecting bracket 3, the positioning bolt 712 is inserted into the rear connecting bracket 3 and the mounting bracket 711, the washer 713 and the spring 714 are sleeved on the outer peripheral wall of the positioning bolt 712, and the positioning nut 715 is threaded onto the outer peripheral wall of the positioning bolt 712.

[0040] At this point, adjust the guide rod 7 to a suitable angle, and compress the spring 714 by rotating the positioning nut 715. This causes the spring 714 to push the washer 713 to press against the mounting bracket 711, which in turn causes the mounting bracket 711 to clamp the rear connecting bracket 3, ensuring the connection between the guide rod 7 and the rear connecting bracket 3. Fix the guide rod 7 at a suitable angle, and adjust the axis of the flow meter 6 to be parallel to the water flow direction to reduce the error caused by the flow direction deviation angle.

[0041] Connection unit 2 includes:

[0042] The main rod 21 is fixedly connected to the front end of the lead fish body 1;

[0043] Support rod 22 is fixedly connected to main rod 21, and the top of main rod 21 is installed with radar wave tester 5;

[0044] Clamp 23 is slidably connected to the outer peripheral wall of main rod 21;

[0045] A connector rod 24 is provided below the clamp 23, and the connector rod 24 is inserted into the comparison frame 4.

[0046] The radar wave tester 5 is installed on the main body 1 of the lead fish via the support rod 22. The flow meter 6 is then installed on the comparison frame 4 below the plug rod 24. The radar wave tester 5 and the flow meter 6 are installed on the main body 1 of the lead fish at the same time. The radar wave tester 5 and the flow meter 6 are compared and measured simultaneously. Through synchronous comparison, the surface flow velocity measured by the radar wave tester 5 can be directly compared with the vertical flow velocity data obtained by the flow meter 6, thus verifying the measurement accuracy of the radar wave tester 5 under complex water flow conditions.

[0047] By adjusting the clamp 23 to slide on the main rod 21, the positions of the comparison frame 4 and the flow meter 6 are adjusted. The flow meter 6 is adjusted to be offset from the radar wave tester 5 by a certain position so that they do not interfere with each other during flow measurement. When the clamp 23 drives the comparison frame 4 and the flow meter 6 to a suitable position on the main rod 21, the bolts are tightened to fix the clamp 23 to the main rod 21, thus fixing the comparison frame 4 and the flow meter 6 to the main rod 21.

[0048] The plug rod 24 has a first plug groove 25, the measuring frame 4 has a first corresponding hole 41, the first corresponding hole 41 coincides with the first plug groove 25, and the outer peripheral wall of the mounting rod 42 is fitted with a fixing frame 44.

[0049] By fitting the top of the comparison frame 4 onto the outer peripheral wall of the insertion rod 24, when the first corresponding hole 41 coincides with the first insertion groove 25, the bolt is inserted into the first corresponding hole 41 and the first insertion groove 25 to fix the comparison frame 4 to the first insertion groove 25.

[0050] When installing the flow meter 6, the flow meter 6 is sleeved on the outer peripheral wall of the mounting rod 42, and then the fixing bracket 44 is sleeved on the outer peripheral wall of the mounting rod 42. At this time, the fixing bracket 44 is in contact with the bottom end face of the flow meter 6, and the fixing bracket 44 is used to install the flow meter 6 on the mounting rod 42.

[0051] The mounting rod 42 has a second insertion slot 43, and the fixing bracket 44 has a second corresponding hole 45, which is set to correspond to the second insertion slot 43.

[0052] When the fixing bracket 44 is fitted onto the outer peripheral wall of the mounting rod 42, and the second insertion groove 43 coincides with the second corresponding hole 45, the bolt is inserted into the second insertion groove 43 and the second corresponding hole 45, and the second corresponding hole 45 is fixed to the outer peripheral wall of the mounting rod 42.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
