Description

Technical Field

[0001] This utility model relates to the field of flow measurement device technology, and in particular to a flow measurement device for hydrological testing. Background Technology

[0002] Hydrological flow measurement devices are key equipment for measuring water flow. They are divided into two categories: contact and non-contact. Contact devices, such as hydrological cableway systems, survey vessels, and ADCPs, require direct contact with the water body. Non-contact devices, on the other hand, do not require contact with the water body. Radar wave flow meters are a typical example. Based on the Doppler effect, radar wave flow meters measure the surface velocity of water by emitting microwaves and calculate the flow rate by combining cross-sectional parameters. They are not affected by water turbidity or floating debris, can be remotely controlled, operate in all weather conditions, and have a high degree of automation. They are widely used in hydrological monitoring, flood control, and other fields.

[0003] In existing technologies, radar wave flow meters are used to fix and support the flow meter above the river channel using a bracket. When it is necessary to measure the flow velocity at different cross-sections or locations of the river channel, it is difficult to adjust the position of the radar wave flow meter according to the measurement needs because the position of the radar wave flow meter is fixed, which reduces the practicality of the radar wave flow meter.

[0004] Therefore, a flow measurement device for hydrological testing is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that when it is necessary to measure the flow velocity at different cross-sections or locations of a river, it is difficult to adjust the position of the radar wave flow meter according to the measurement needs because the position of the radar wave flow meter is fixed. Therefore, this invention proposes a flow measurement device for hydrological testing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flow measuring device for hydrological testing, comprising a support frame, a servo motor fixedly mounted on the upper end of the support frame, a reel fixedly mounted on the side wall of the support frame, a traction cable wound around the circumferential surface of the servo motor, the traction cable slidingly passing through the support frame, a lead block fixedly mounted on one end of the traction cable, a T-shaped block fixedly mounted on the surface of the traction cable, a radar wave flow meter fixedly mounted on the lower surface of the T-shaped block, a support rod fixedly mounted on the inner wall of the support frame, and the T-shaped block slidably sleeved on the circumferential surface of the support rod.

[0007] The effect achieved by the above components is as follows: by setting up components such as servo motors, reels, traction cables, lead blocks, and radar wave flow meters, when it is necessary to adjust the horizontal position of the radar wave flow meter during hydrological surveys, the position of the radar wave flow meter can be adjusted by controlling the rotation direction of the output end of the servo motor in cooperation with the lead blocks and traction cables. This makes it convenient to use the radar wave flow meter to measure the flow velocity at different cross-sections or positions of the river channel, thus improving the practicality of the radar wave flow meter.

[0008] Preferably, two clamping plates are fixedly mounted on the circumferential surface of the reel, and the traction cable is located between the two clamping plates.

[0009] The effect achieved by the above components is that the two clamps can ensure that the reel can stably wind up the traction cable.

[0010] Preferably, a baffle is fixedly fitted to the outer wall of the support frame, and the clamp is slidably connected to the baffle.

[0011] The effect achieved by the above components is that the baffle can prevent foreign objects from being drawn in during the winding process.

[0012] Preferably, a scraper ring is fixedly fitted to the outer wall of the support frame. The scraper ring has a trumpet-shaped structure, and the traction cable slides through the scraper ring.

[0013] The effect achieved by the above-mentioned components is that the scraper can scrape off impurities attached to the surface of the traction cable during the winding process, thus preventing impurities from affecting the normal sliding of the traction cable.

[0014] Preferably, a fixing block is fixedly assembled on the upper surface of the T-shaped block, an electric push rod is fixedly assembled inside the fixing block, and a push plate is fixedly assembled at the output end of the electric push rod.

[0015] The effect achieved by the above components is as follows: when the radar wave flow meter moves to the target position, the electric push rod in the fixed block is activated, and the T-shaped block is locked by friction to prevent the position of the radar wave flow meter from shifting due to water flow impact or vibration during the measurement process.

[0016] Preferably, a plurality of rough pads are fixedly mounted on the side of the push plate away from the fixing block.

[0017] The effect achieved by the above components is that the rough pad can increase the friction between the push plate and the support frame.

[0018] Preferably, a guide rod slides through the fixed block, and the guide rod is fixedly connected to the push plate.

[0019] The effect achieved by the above components is that the guide rod slides synchronously with the push plate, ensuring smooth movement of the push plate and improving locking reliability.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In this invention, by setting up components such as a servo motor, a reel, a traction cable, a lead block, and a radar wave flow meter, when it is necessary to adjust the horizontal position of the radar wave flow meter during hydrological surveys, the position of the radar wave flow meter can be adjusted by controlling the rotation direction of the output end of the servo motor in cooperation with the lead block and the traction cable. This facilitates the use of the radar wave flow meter to measure the flow velocity at different cross-sections or positions of the river channel, thus improving the practicality of the radar wave flow meter.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] like Figures 1-4As shown, this utility model provides a flow measurement device for hydrological testing, including a support 1. A support frame 2 is fixedly mounted on the upper end of the support 1. A servo motor 3 is fixedly mounted on the side wall of the support 1. A reel 4 is fixedly mounted on the output end of the servo motor 3. A traction cable 5 is wound around the circumference of the reel 4. The traction cable 5 slides through the support frame 2. A lead block 6 is fixedly mounted on one end of the traction cable 5. A T-shaped block 7 is fixedly mounted on the surface of the traction cable 5. A radar wave flow meter 8 is fixedly mounted on the lower surface of the T-shaped block 7. A support frame 2 is fixedly mounted on the inner wall of the support frame 2. The rod 17 and the T-shaped block 7 are slidably sleeved on the circumference of the support rod 17. By setting up components such as servo motor 3, roller 4, traction cable 5, lead block 6 and radar wave flow meter 8, when it is necessary to adjust the horizontal position of radar wave flow meter 8 during hydrological surveys, the position of radar wave flow meter 8 can be adjusted by controlling the rotation direction of the output end of servo motor 3 with the cooperation of lead block 6 and traction cable 5. This makes it convenient to use radar wave flow meter 8 to measure the flow velocity at different cross sections or positions of the river channel, thus improving the practicality of radar wave flow meter 8.

[0030] Two clamping plates 9 are fixedly mounted on the circumferential surface of the reel 4. The traction cable 5 is located between the two clamping plates 9. The two clamping plates 9 can ensure that the reel 4 can stably wind the traction cable 5. A baffle 10 is fixedly mounted on the outer wall of the support frame 2. The clamping plates 9 and the baffle 10 are slidably connected. The baffle 10 can prevent foreign objects from being rolled in during the winding process. A scraper ring 11 is fixedly mounted on the outer wall of the support frame 2. The scraper ring 11 has a trumpet-shaped structure. The traction cable 5 slides through the scraper ring 11. The scraper ring 11 can scrape off impurities attached to the surface of the traction cable 5 during the winding process, so as to prevent impurities from affecting the normal sliding of the traction cable 5.

[0031] A fixing block 12 is fixedly mounted on the upper surface of the T-shaped block 7. An electric push rod 13 is fixedly mounted inside the fixing block 12. A push plate 14 is fixedly mounted on the output end of the electric push rod 13. When the radar wave flow meter 8 moves to the target position, the electric push rod 13 inside the fixing block 12 is activated. The T-shaped block 7 is positioned and locked by friction, preventing the position of the radar wave flow meter 8 from shifting due to water flow impact or vibration during the measurement process. Several rough pads 15 are fixedly mounted on the side of the push plate 14 away from the fixing block 12. The rough pads 15 can increase the friction between the push plate 14 and the support frame 2. A guide rod 16 slides through the fixing block 12. The guide rod 16 is fixedly connected to the push plate 14. The guide rod 16 slides synchronously with the push plate 14 to ensure the smooth movement of the push plate 14 and improve the locking reliability.

[0032] The overall working principle is as follows: When hydrological testing is required, the support 1 is installed at a suitable location on the riverbank. During the hydrological testing process, when the horizontal position of the radar wave current meter 8 needs to be adjusted, the servo motor 3 is activated. The output of the servo motor 3 drives the reel 4 to rotate. When the reel 4 unwinds the traction cable 5, the lead block 6 will fall due to its own weight, which will move the traction cable 5. The traction cable 5 will then cause the T-shaped block 7 to slide along the circumference of the support rod 17. The traction cable 5 will be tightened by the lead block 6. The movement of the T-shaped block 7 will cause the radar wave current meter 8 to move away from the support 1. When the reel 4 winds up the traction cable 5, the traction cable 5 will cause the T-shaped block 7 to slide in the opposite direction. At this time, the radar wave current meter 8 will move closer to the support. The direction of movement is 1. Therefore, with the cooperation of lead block 6 and traction cable 5, the position of radar wave flow meter 8 can be adjusted by controlling the rotation direction of the output end of servo motor 3. This makes it convenient to use radar wave flow meter 8 to measure the flow velocity of different cross sections or different positions of the river channel, thus improving the practicality of radar wave flow meter 8. During the process of reel 4 winding traction cable 5, two clamps 9 can ensure that reel 4 can stably wind traction cable 5. Baffle 10 can prevent foreign objects from being drawn in during the winding process. Scraper ring 11 can scrape off impurities attached to the surface of traction cable 5 during the winding process, preventing impurities from affecting the normal sliding of traction cable 5. After the impurities are scraped off, they will fall into the river channel and be washed away by the river water.

[0033] When the radar wave flow meter 8 moves to the target position, the electric push rod 13 inside the fixed block 12 is activated, pushing the push plate 14 to move until the rough pad 15 on the push plate 14 is in close contact with the support frame 2. The T-block 7 is locked in place by friction, preventing the position of the radar wave flow meter 8 from shifting due to water flow impact or vibration during the measurement process. The rough pad 15 can increase the friction between the push plate 14 and the support frame 2. The guide rod 16 slides synchronously with the push plate 14 to ensure the smooth movement of the push plate 14 and improve the locking reliability. During the measurement process, the radar wave flow meter 8 emits microwaves based on the Doppler effect, measures the water surface velocity and calculates the flow rate by combining the cross-sectional parameters, and completes the hydrological measurement work.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
