Description

Integrated video water level, velocity and flow meter Technical Field

[0001] This utility model relates to the field of flow meter technology, specifically an integrated video water level and velocity flow meter. Background Technology

[0002] Flow meters are the eyes of industrial production and are closely related to the national economy, national defense, and scientific research. They occupy an important position and role in the national economy and can be used to measure the flow rate of media such as gas, liquid, and steam. Flow meters can also be used to measure the flow velocity of river water.

[0003] The integrated video water level, velocity, and flow meter is a device that integrates multiple advanced technologies and can simultaneously monitor water level, velocity, and flow rate, providing important data support for water resource management and environmental protection.

[0004] A search revealed that in a patent publication number CN219244742U, a fast-flow-velocity water level measuring device for water conservancy engineering testing was proposed that "the fast-flow-velocity water level measuring device for water conservancy engineering testing can ensure the stability of the overall measuring device, avoid tilting or tipping that would affect normal measurement work, and can flexibly adjust the measuring position according to the width of the river channel during measurement, avoiding inaccurate measurement due to insufficient position";

[0005] However, the above solution still has certain shortcomings in practical use. During the process of accurately measuring the flow velocity in the canal using the flow meter, we found that some garbage and other foreign objects in the river water move with the water flow. These moving foreign objects interfere with the flow meter's detection, thus affecting the accuracy of the flow meter's measurement of the river water velocity. This interference may lead to deviations in the final measurement results, failing to truly reflect the actual velocity of the water flow in the canal. Summary of the Invention

[0006] This invention provides an integrated video water level, flow rate and flow meter to solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an integrated video water level, flow rate and flow meter, including a water channel structure, with a barrier device and a metering device arranged above the water channel structure, and the metering device located behind the barrier device;

[0008] The barrier device includes a drive box, inside which a hinge rod is connected via a geared motor. A lifting platform is movably sleeved at the end of the hinge rod. A connecting rod is fixedly installed at the bottom of the lifting platform. The bottom end of the connecting rod extends to the bottom of the drive box and is fixedly installed with a mounting bracket. A barrier frame is movably inserted into the interior of the mounting bracket.

[0009] Furthermore, the water channel structure includes a water channel body, an outer plate is fixedly installed on the outside of the water channel body, and the top of the outer plate is connected to the bottom of the blocking device and the metering device.

[0010] Furthermore, the metering device includes a connecting frame, on the front side of which a flow meter and a water level gauge are fixedly installed.

[0011] Furthermore, the lifting platform has a horizontal groove inside, and the end of the hinge rod is located inside the horizontal groove and is slidably connected to the inside of the horizontal groove.

[0012] Furthermore, the mounting bracket has a sliding groove inside, and a slider is fixedly installed at the bottom of the barrier frame, with the slider overlapping the inner wall of the sliding groove.

[0013] Furthermore, a follower rack is installed at the bottom of the lifting platform, and the bottom of the follower rack is fixedly connected to the top of the mounting frame. A locking rack is movably connected inside the drive box through a hydraulic cylinder, and the locking rack meshes with the follower rack.

[0014] Compared with the prior art, this utility model provides an integrated video water level, flow rate and flow meter, which has the following beneficial effects:

[0015] This integrated video water level, velocity, and flow meter effectively intercepts and blocks various impurities and foreign objects in the water flow by using a barrier frame inside the mounting bracket. These barrier frames play a crucial filtering role in the water flow, ensuring water cleanliness. Simultaneously, the geared motor inside the drive box, through precise control, drives the hinge rod to move precisely. The movement of the hinge rod drives the lifting platform, which in turn causes the barrier frame inside the mounting bracket to retract effectively. This coordinated action reduces interference from foreign objects in the water flow on the metering equipment's detection process. Therefore, the metering equipment can more accurately measure the river water flow velocity, ensuring the accuracy and reliability of the measurement results. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4. This utility model discloses an integrated video water level and flow rate meter, including a water channel structure 1. An obstruction device 2 and a metering device 3 are arranged above the water channel structure 1, and the metering device 3 is located behind the obstruction device 2.

[0023] The water channel structure 1 includes a water channel body 101, and an outer plate 102 is fixedly installed on the outside of the water channel body 101. The top of the outer plate 102 is connected to the bottom of the barrier device 2 and the metering device 3.

[0024] The barrier device 2 includes a drive box 201. Inside the drive box 201, a hinge rod 203 is connected to the drive box 201 via a geared motor 202. The end of the hinge rod 203 is movably sleeved with a lifting platform 204. A connecting rod 205 is fixedly installed at the bottom of the lifting platform 204. The bottom end of the connecting rod 205 extends to the bottom of the drive box 201 and is fixedly installed with a mounting bracket 206. A barrier frame 207 is movably inserted into the mounting bracket 206.

[0025] By utilizing the barrier frame 207 inside the mounting bracket 206, various impurities and foreign objects in the water flow can be effectively intercepted and blocked. These barrier frames 207 play a crucial filtering role in the water flow, ensuring the cleanliness of the water. At the same time, the geared motor 202 inside the drive box 201, through precise control, can drive the hinge rod 203 to move precisely. The movement of the hinge rod 203 drives the lifting platform 204, which in turn causes the barrier frame 207 inside the mounting bracket 206 to perform an effective retraction operation. The coordinated work of this series of actions reduces the interference of foreign objects in the water flow on the detection process of the metering device 3. Therefore, the metering device 3 can more accurately measure the river water flow velocity, thereby ensuring the accuracy and reliability of the measurement results.

[0026] Specifically, the metering device 3 includes a connecting frame 301, on the front side of which a flow meter 302 and a water level gauge 303 are fixedly installed.

[0027] In this implementation scheme, both the flow meter 302 and the water level meter 303 are radar instruments, and their models can be HY.LDZ-1 and YCRD800, respectively. They are capable of measuring the water level by scanning the water flow and water level. The specific measurement method is a known technology of existing radar instruments and will not be described in detail here.

[0028] Specifically, the lifting platform 204 has a horizontal groove inside, and the end of the hinge rod 203 is located inside the horizontal groove and is slidably connected to the inside of the horizontal groove.

[0029] In this embodiment, the hinge rod 203 can slide within the transverse groove, ensuring the stable movement of the lifting platform 204 in the vertical direction and avoiding equipment failure or measurement errors caused by unstable movement.

[0030] Specifically, the mounting bracket 206 has a sliding groove inside, and the bottom end of the barrier frame 207 is fixedly installed with a slider, which overlaps with the inner wall of the sliding groove.

[0031] In this embodiment, the design of the slider overlapping the inner wall of the groove allows the barrier frame 207 to be quickly disassembled and assembled inside the mounting bracket 206. This design facilitates the cleaning or replacement of the barrier frame 207, making maintenance simple and convenient.

[0032] Specifically, a follower rack 210 is installed at the bottom of the lifting platform 204, and the bottom of the follower rack 210 is fixedly connected to the top of the mounting frame 206. A locking rack 209 is movably connected inside the drive box 201 through a hydraulic cylinder 208, and the locking rack 209 meshes with the follower rack 210.

[0033] In this embodiment, when locking the lifting platform 204 is required, the hydraulic cylinder 208 is activated, causing the locking rack 209 to move laterally. This ensures the locking rack 209 precisely engages with the follower rack 210, effectively locking and fixing the lifting platform 204 in a specific position. This locking mechanism prevents unnecessary movement or shaking of the lifting platform 204 due to water flow or other external forces. This significantly improves the stability of the entire device and plays a crucial role in ensuring the accuracy and safety of the measurement process. This thoughtful design ensures reliable operation of the equipment in various environments and greatly enhances the safety of operators during related tasks.

[0034] In use, the device is first installed above the water channel where flow rate measurement is required. The blocking device 2 and the metering device 3 are then securely mounted on the outside of the water channel body 101 via the external plate 102. Next, the geared motor 202 inside the drive box 201 is activated. The output shaft of the geared motor 202 drives the hinge rod 203 to rotate. Since the end of the hinge rod 203 is movably sleeved inside the lifting platform 204, and the lifting platform 204 is connected to the mounting frame 206 via the connecting rod 205, the rotational motion of the hinge rod 203 is converted into the up-and-down movement of the lifting platform 204. As the lifting platform 204 rises or falls, the blocking frame 207 inside the mounting frame 206 also rises or falls accordingly, thereby achieving the blocking and filtration of impurities in the water flow.

[0035] When the barrier frame 207 needs to be cleaned or replaced, the operator can easily remove the barrier frame 207 from the mounting bracket 206 by means of the design of the slider overlapping the inner wall of the slide groove, so as to carry out cleaning or replacement operations. Maintenance is simple and convenient.

[0036] During the measurement process, the flow meter 302 and water level gauge 303 in the metering device 3 measure the flow velocity and water level in the canal, respectively. Due to the presence of the barrier device 2, the interference of foreign objects in the water flow on the detection process of the metering device 3 is effectively reduced. Therefore, the metering device 3 can measure the river flow velocity more accurately, thereby ensuring the accuracy and reliability of the measurement results.

[0037] In addition, this device is equipped with a locking mechanism. When it is necessary to lock the lifting platform 204, the hydraulic cylinder 208 is activated, causing the hydraulic cylinder 208 to drive the locking rack 209 to move laterally. This causes the locking rack 209 to precisely mesh with the follower rack 210, thereby effectively locking and fixing the lifting platform 204 in a specific position. The existence of this locking mechanism can prevent the lifting platform 204 from unnecessary movement or shaking due to the impact of water flow or any other external force, further improving the stability of the entire device and the accuracy and safety of the measurement process.

[0038] In summary, this integrated video water level, velocity, and flow meter, utilizing the barrier frame 207 inside the mounting bracket 206, can effectively intercept and block various impurities and foreign objects in the water flow. These barrier frames 207 play a crucial filtering role in the water flow, ensuring water quality cleanliness. Simultaneously, the geared motor 202 inside the drive box 201, through precise control, can drive the hinge rod 203 to move precisely. The movement of the hinge rod 203 drives the lifting platform 204, thereby prompting the barrier frame 207 inside the mounting bracket 206 to perform an effective retraction operation. This series of coordinated actions reduces the interference of foreign objects in the water flow on the detection process of the metering device 3. Therefore, the metering device 3 can more accurately measure the river water flow velocity, thus ensuring the accuracy and reliability of the measurement results.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
