Description

Technical Field

[0001] The utility model relates to the field of water body detection, in particular to a floating sludge depth detection device. Background Art

[0002] At present, there are two methods for monitoring the thickness of pipeline silt: one is the traditional manual probe measurement method, and the other is an online silt monitoring device fixed in situ in the water body.

[0003] The manual probe measurement method requires the measuring rod to penetrate the pipe network for measurement. When the inspection well of the pipe network is small, manual operation is difficult. In addition, when long-term monitoring is required, frequent manual measurement is required. Manual monitoring can usually only obtain a single silt thickness data at a time, and it is difficult to obtain other water conditions data at the same time. If other data is required, it often requires multiple measurements, which results in a huge loss of human resources and cannot achieve real-time monitoring. For fixed-installed silt online monitoring devices, due to the complex water conditions in the pipe network, the silted pipes are mostly sewage pipes, and there is a large amount of garbage in the water. The fixed silt online monitoring device will be mounted with a large amount of garbage during long-term operation, resulting in the garbage covering the probe, causing the equipment detection to fail. Therefore, the fixed silt online monitoring device needs to be frequently maintained to clean the mounted garbage. It can be seen that when long-term monitoring of silt thickness is required, manual probe measurement requires a lot of manpower during detection, while fixed-installed silt online monitoring devices require a lot of manpower during maintenance. Both detection methods consume a lot of manpower and are not suitable for long-term monitoring. Utility Model Content

[0023] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0024] The following is combined with Figure 1-2 This application is described in further detail.

[0025] The embodiment of the present application discloses a floating sludge depth detection device.

[0026] Reference Figure 1 The floating silt depth detection device includes a floating detection platform, a fixed component and a traction component connecting the floating detection platform and the fixed component. The floating detection platform includes a float 1 for floating on the water surface and a sensor arranged on the float 1. The fixed component is fixed on a substrate next to the water body. The traction component is flexible so that the floating detection platform can maintain balance under the impact of water flow.

[0027] The float 1 is the main part of the floating detection platform, which is used to float on the water surface. The main function of the float 1 is to support and carry various sensors so that they can be stably / reliably measured in the water body. Compared with the fixed silt depth online monitoring device, the floating detection platform can automatically adjust the height as the water level rises or falls, always keeping the sensor in the best measurement position to ensure the accuracy of the measurement data. The fixed component is used to be fixed on the substrate beside the water body to provide support. When measuring the silt depth in the pipe network, the fixed component can be installed on the well wall; when measuring the silt depth in the river channel, the fixed component can be installed on the river bank or the shore. The floating detection platform and the fixed component are connected by a flexible traction component. Under the action of water flow or external force, the float 1 can pitch or roll freely to avoid equipment damage or measurement errors caused by being fixed. The flexible design of the traction component ensures that the float 1 always remains stable under the action of external force and will not be damaged by violent movement.

[0028] When in use, the staff only needs to install the fixed component on the base next to the water body to be tested, and then connect the floating detection platform to the fixed component through the traction component. The floating detection platform floats on the water surface under the action of buoyancy and moves under the drive of the water flow. When the traction component is tightened, the floating detection platform reaches the monitoring position. The sensors carried on the floating detection platform can obtain various parameters of the water body in real time, and can monitor for a long time without repeatedly disassembling and assembling the detection device.

[0029] In one embodiment, the fixing assembly includes a mounting seat 12 and a vertical rod 10, a positioning column 16 is provided on the mounting seat 12 along the direction of the vertical rod 10, and a positioning sleeve 14 is provided on the vertical rod 10 to be plugged with the positioning column 16. This design allows the vertical rod 10 to be easily connected and separated from the mounting seat 12. The plug-in design of the positioning column 16 and the positioning sleeve 14 makes the installation and disassembly process simple and quick, without the need for complex tools and operations, saving manpower and time. Through the plug-in design of the positioning column 16 and the positioning sleeve 14, the height and position of the vertical rod 10 can be easily adjusted to adapt to different water environments and measurement requirements.

[0030] A clamp 15 is provided on the vertical rod 10, and a positioning sleeve 14 is installed on the clamp 15. A support platform for fitting with the outer wall of the vertical rod 10 is provided on the mounting seat 12. The clamp 15 allows the positioning sleeve 14 to be flexibly adjusted on the vertical rod 10, and the height can be adjusted as needed to adapt to different water levels and installation requirements. The support platform fits with the outer wall of the vertical rod 10 to provide additional support and stability for the vertical rod 10, and prevent the vertical rod 10 from tilting or shifting under the influence of water flow.

[0031] A circuit processing system 5 is provided inside the floating body 1. The circuit processing system 5 is connected to the data acquisition terminal 13 via a cable to provide real-time monitoring data. The cable is passed through the vertical pole 10 to avoid damage.

[0032] In one embodiment, the traction assembly includes a cross bar 11 and traction ropes 8 respectively located at both ends of the cross bar 11, the two traction ropes 8 are connected to the same position at the head end of the float 1, and the midpoint position in the length direction of the cross bar 11 is connected to the fixed assembly. Through such a design, the isosceles triangle structure formed by the cross bar 11 and the traction ropes 8 ensures the stability of the float 1 in the water flow. The two traction ropes 8 are connected to the same position at the head end of the float 1, so that when the float 1 is impacted by the water flow or external force, its force direction is more consistent, reducing the lateral and longitudinal swing of the float 1. In the process of installing the detection device, the staff only needs to place the floating detection platform on the water surface. Since the two traction ropes 8 are of equal length, the floating detection platform will automatically adjust its posture when it moves with the water flow. There is no need to manually adjust the posture of the equipment, which reduces the construction steps and improves the work efficiency of the equipment installation personnel. Specifically, the traction rope 8 can be a wire rope to maintain sufficient strength while being flexible and reduce the risk of disconnection of the traction rope 8.

[0033] In order to reduce the risk of garbage being mounted on the float 1, in one embodiment, a water-facing surface is formed at the head end of the float 1. The float 1 is a streamlined design with a pointed head at the head end to reduce the area of ​​the water-facing surface. The width of the float 1 gradually increases from the head end to the tail end. Such a pointed streamlined design minimizes the area of ​​the water-facing surface of the float 1. When there is garbage and floating objects in the water flow, the float 1 can pass through these obstacles more easily, reducing the probability of garbage being mounted on the float 1. The width of the float 1 gradually increases from the head end to the tail end, so that garbage and floating objects in the water flow are not easy to accumulate in the water area near the tail end of the float 1, ensuring the accuracy and reliability of sensor detection. It can be understood that the width increases from the head end to the tail end to make the float triangular, or the width increases from the head end to a certain area in the middle of the float and stops increasing, which are all considered to be increasing in width from the head end to the tail end.

[0034] In one embodiment, an upturned portion is formed at the front end of the float 1, so that the oncoming water flow and garbage can slide down along the curve of the float 1, thereby avoiding direct collision and hanging on the front end of the float 1. This design is similar to the bow of a ship, which can guide the water flow and floating objects to bypass the float 1. When the garbage contacts the float 1 along the water flow, the upward-curved design can guide the garbage downward and to the sides, thereby reducing the probability of the garbage directly staying and accumulating at the front end of the float 1; in one embodiment, the thickness of the float 1 gradually increases from the front end to the rear end. The increasing thickness design gradually increases the surface area of ​​the float 1. When the garbage contacts the float 1, the thickness change will generate a gradually increasing separation force, making it difficult for the garbage to adhere to and stay on the float 1. The inclined surface formed by the gradually increasing thickness makes it easier for the garbage to slide and fall along the surface of the float 1, similar to the slope effect, which enhances the self-cleaning ability of the float 1.

[0035] Reference Figure 2 In one embodiment, the head end of the floating body 1 is provided with a fixing hole 9 for connecting a traction rope 8 and a cable outlet hole 7 for passing a detection line.

[0036] Reference Figure 2 In one embodiment, the sensor includes a first distance sensor 4 for detecting the distance between the water surface and the top of the pipeline and a second distance sensor 2 for detecting the distance between the water surface and the mud surface. When monitoring the mud depth in the pipe network, the first distance sensor 4 can measure the distance from the water surface to the top of the pipe, and the second distance sensor 2 can measure the distance from the water surface to the mud surface. The mud depth can be obtained by subtracting the measured distance from the water surface to the top of the pipe from the known pipe diameter, and then subtracting the measured distance from the water surface to the mud surface. Specifically, the first distance sensor 4 is a radar ranging sensor, and the radar ranging sensor probe is installed on the upper part of the floating body 1. The second distance sensor 2 is a Doppler ranging sensor, and the Doppler ranging sensor probe is installed downward at the lower part of the floating body 1.

[0037] In one embodiment, the floating silt depth detection device further comprises a water level meter. When measuring the silt depth in the river channel, the silt depth can be obtained by subtracting the distance from the water surface to the riverbed measured by the second distance sensor 2 from the distance from the water surface to the mud surface.

[0038] In one embodiment, the sensor also includes a velocity sensor 3 and / or an angle sensor 6. Specifically, the velocity sensor 3 is a Doppler velocity sensor 3. The probe of the Doppler velocity sensor 3 is installed obliquely underwater at the rear of the floating body 1, and is used to measure the vertical flow velocity of the cross section in the pipeline. It can measure the water flow velocity by layering when in contact with the water body. Compared with the radar flow meter, the accuracy of the flow measurement data is improved, and there is no need to install it on the bottom of the river channel, ensuring that the instrument is not covered by silt. The angle sensor 6 is installed inside the floating body 1. Through the angle sensor 6, the posture changes of the pitch angle and roll angle of the floating body 1 in the water are sensed, and the collected data is calibrated in time to ensure the accuracy of the collected equipment monitoring data.

For those skilled in the art, the utility model can have various modifications and changes.
