Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a multifunctional detection device for water conservancy engineering detection. Background Technology

[0002] As a crucial infrastructure for national economic and social development, the safe and stable operation of water conservancy projects directly impacts the safety of people's lives and property, the rational allocation of water resources, and the balance of the ecological environment. Throughout the entire lifecycle of water conservancy projects, continuous monitoring of multiple indicators, such as water level, seepage flow, deformation, stress and strain, and water quality, is necessary to monitor the project's operational status in real time and provide early warnings of potential safety hazards. With the continuous expansion of water conservancy project scale (such as large reservoirs and inter-basin water transfer projects) and the increasing complexity of operating environments (exacerbated by extreme weather and geological changes), higher demands are placed on the real-time nature, accuracy, and comprehensive correlation of monitoring data. Water conservancy monitoring devices, as the core carrier of data acquisition, directly determine the efficiency of project safety monitoring and management through their technical performance.

[0003] For example, in the prior art, a water level detection device for water conservancy projects (publication number: CN211904320U) includes a water gate, a supporting float, and an ultrasonic rangefinder. A detection rod is installed at the bottom of the supporting float. A flashlight and a sound shield generator are electrically connected to the output of a central processing unit. The ultrasonic rangefinder is fixedly installed at the bottom of the supporting float, and its output is electrically connected to the input of the central processing unit. An alarm is installed at the output of the central processing unit. This water level detection device for water conservancy projects facilitates the detection of water levels near the water conservancy project during use.

[0004] However, in the process of conducting water conservancy project testing using existing technologies, it is often necessary to sample the silt or water at the corresponding water level and conduct relevant analysis in order to further improve the testing effect and accurately determine the further construction operations for the water conservancy project. However, the aforementioned devices can only perform water level measurement in actual use, and other devices are required to perform the corresponding sampling and testing, which seriously affects the efficiency of water conservancy project testing.

[0009] A further feature of this invention is that the detection device also includes a top cover, which is detachably connected to the opening of the sampling bucket via a flange, and the center of the top cover is fixedly connected to the take-up roller via a traction rope.

[0010] A further feature of this invention is that the bottom of the sampling bucket is fixedly connected to two clamping covers via a flange; a support frame is provided between each electromagnetic water valve and the bottom of the sampling bucket, and the electromagnetic water valve is fixedly connected to the sampling bucket via the support frame.

[0014] A further feature of this invention is that one end of each L-shaped tube passing through the support plate is threaded with a sealing cap, and the other end extending out of the sampling bucket wall is threaded with a water-permeable cap.

[0015] The beneficial effects of this utility model are: In this invention, by incorporating a clamping cover and geotextile covering the water pressure sensor within the water sampling mechanism, debris and silt can be prevented from entering the sensor's measurement range while allowing water to flow smoothly. This provides a clean detection environment for the water pressure sensor, ensuring the stability and reliability of the water level measurement data. Simultaneously, the use of several L-shaped tubes and electromagnetic water valves within the sampling bucket enables targeted sampling of water samples at different depths, improving the device's detection accuracy and versatility, and enhancing the efficiency of water conservancy engineering testing.

[0020] The following is in conjunction with the appendix Figure 1-7 The present invention will be further described below.

[0021] To address the problems existing in the background art, this application proposes the following technical solution: In this utility model, such as Figure 1 , Figure 2 , Figure 3As shown, a multifunctional detection device for water conservancy engineering inspection includes a small detection boat 1 and a take-up roller 2 mounted on the small detection boat 1. The end of the traction rope of the take-up roller 2 is fixedly connected to the detection device. The purpose of the take-up roller 2 is to facilitate the user to place the detection device into the water using the traction rope on the take-up roller 2. The detection device includes a water sample collection mechanism and a water level measurement component distributed vertically. The water level measurement component includes two clamping covers 3 fixedly connected to the bottom of the water sample collection mechanism. The lower ends of the two clamping covers 3 are fixedly connected to a partition 4. A water pressure sensor 5 is fixedly installed at the center of the upper surface of the partition 4. The function of sensor 5 is to allow the user to obtain the water level depth data of the water area after certain calculations based on the water pressure signal returned by the water pressure sensor 5 after it is placed in the water. Geotextile 6 is wrapped around the water pressure sensor 5 between the two clamping covers 3. By setting the clamping covers 3, the geotextile 6 can be firmly clamped and wrapped around the water pressure sensor 5, blocking silt and debris of a certain depth from entering the measuring range of the water pressure sensor 5, while allowing water to flow smoothly into the measuring range of the water pressure sensor 5, providing a clean working environment for the water pressure sensor 5 and ensuring the stable operation of the water pressure sensor 5. The water sampling mechanism includes a sampling bucket 7. Inside the sampling bucket 7, there is a support plate 8 that is parallel to the bottom of the bucket and fixedly connected to the bucket wall. Several L-shaped tubes 9 are arranged in a circular array on the support plate 8. The function of the support plate 8 is to ensure that each L-shaped tube 9 can be firmly installed inside the sampling bucket. One end of each L-shaped tube 9 passes vertically upward through the support plate 8, and the other end extends horizontally out of the bucket wall of the sampling bucket 7. An electromagnetic water valve 10 is installed on the section of each L-shaped tube 9 inside the sampling bucket 7 near the extended end. By setting several L-shaped tubes 9 and electromagnetic water valves 10, users can sample water bodies at multiple different depths as needed.

[0022] Specifically, when the user submerges the detection device in water using a traction rope, different water depths can be determined based on the signals transmitted by the water pressure sensor. Once a predetermined depth is reached, the user can adjust a solenoid water valve 10 to open it. Water will then enter the L-shaped tube 9, which is submerged in water and extends out of the sampling bucket 7. After the water has been open for a period of time, the solenoid water valve 10 can be adjusted to close it. At this time, a portion of the water will be trapped by the valve of the solenoid water valve 10. This portion of the water trapped in the L-shaped tube 9 can be temporarily stored in the L-shaped tube 9 as the water sample to be tested.

[0023] In this utility model, such as Figure 1 , Figure 2 As shown, a mounting bucket 11 is welded to the bottom opening of the partition 4. A motor 27 is fixedly connected to the center of the bottom of the mounting bucket 11. The main shaft of the motor 27 extends vertically downward through the bottom of the bucket and is fixedly connected to a conical drill bit 12 at its end. By setting up the mounting bucket 11, a sealed working environment can be provided for the motor 27. The function of the motor 27 is to drive the conical drill bit 12 to rotate.

[0024] In this utility model, such as Figure 2 , Figure 4 , Figure 6 , Figure 7 As shown, several sampling holes 13 are arranged in a circular array along the central axis on the working surface of the conical drill bit 12. Each sampling hole 13 is fixedly connected to an electrically controlled butterfly valve 14 near its opening. Above the conical drill bit 12, at the location of each sampling hole 13, a vent hole 15 communicating with its interior is opened. A one-way valve 16 is coaxially installed near the opening of each vent hole 15, and the fluid outlet surface of the one-way valve 16 is covered with geotextile fabric 17. The function of the conical drill bit 12 is twofold: firstly, to ensure the stable operation of the detection device when it reaches the bottom of the riverbed; and secondly, to assist in the silt sampling operation of the sampling holes 13. When the conical drill bit 12 rotates, a large amount of silt will adhere to the drill bit embedded in the silt. For sludge, the user can open the electrically controlled butterfly valve 14 in a sampling hole 13 according to the operation requirements. Without the obstruction of the valve baffle of the electrically controlled butterfly valve 14, the sludge will smoothly enter the sampling hole 13. After the predetermined time, the electrically controlled butterfly valve 14 can be adjusted to close again. At this time, a part of the sludge sample to be tested will be retained in the sampling hole 13. During this process, the function of the vent valve hole and the one-way valve 16 installed inside it is to provide space for volume change for the sludge to enter. The one-way valve 16 can ensure that the compressed air in the sampling hole 13 flows out smoothly. The function of the geotextile 17 is to prevent sludge and other impurities from entering the one-way valve 16, blocking the fluid outlet of the one-way valve 16, and affecting its normal operation.

[0025] In this utility model, such as Figure 2 As shown, the detection device also includes a top cover 18, which is detachably connected to the opening of the sampling bucket 7 via a flange. The center of the top cover 18 is fixedly connected to the take-up roller 2 via a traction rope. By setting a detachable top cover 18, on the one hand, it prevents dirt in the water from entering the sampling bucket 7, and on the other hand, it makes it convenient for the user to open the top cover 18 to perform subsequent maintenance on the components inside the sampling bucket. The traction rope is used to pull and constrain the detection device, making it convenient for the user to take the detection device in and out as needed.

[0026] In this utility model, such as Figure 1 , Figure 2 , Figure 5 As shown, the bottom of the sampling bucket 7 is fixedly connected to two clamping covers 3 via flanges; each electromagnetic water valve 10 is provided with a support frame 19 between it and the bottom of the sampling bucket 7. The electromagnetic water valve 10 is fixedly connected to the sampling bucket 7 via the support frame 19. The function of the support frame 19 is to securely install the electromagnetic water valve 10 on the inner bottom of the sampling bucket 7.

[0027] In this utility model, such as Figure 1 , Figure 2As shown, a number of threaded posts 20 are arranged in a circular array along the central axis on the top of the top cover 18, and each threaded post 20 is vertically and fixedly connected to the top cover 18.

[0028] In this utility model, such as Figure 1 , Figure 2 As shown, a main counterweight 21 is installed above the top cover 18. The function of the main counterweight 21 is to increase the overall weight of the detection device, ensuring that the detection device can smoothly enter the bottom of the water and reduce the error of water level measurement. The main counterweight 21 is passed through the middle and sleeved on each threaded post 20, and is located between the upper and lower nuts 22, which realizes detachable connection. By setting two nuts 22 and simultaneously sleeve the main counterweight 21 on the threaded post 20, the user can add counterweights of different thicknesses by adjusting the gap between the two nuts 22. This is also to reduce the interference of the counterweight on the installation of the top cover 18 below. The top of each threaded post 20 is threadedly connected to a secondary counterweight 23. The function of the secondary counterweight 23 is the same as that of the main counterweight 21.

[0029] In this utility model, such as Figure 3 As shown, a motor 24 is installed on one rotating end of the take-up roller 2 to drive its rotation. The function of the motor is to facilitate the user to control the take-up roller 2 to achieve the take-up action and pull the detection device out of the water.

[0030] In this utility model, such as Figure 1 , Figure 2 , Figure 5 As shown, each L-shaped tube 9 has a sealing cap 25 threadedly connected to one end of its passage through the support plate 8. The function of the sealing cap 25 is twofold: firstly, to prevent water samples temporarily stored in the L-shaped tube 9 from leaking into the sampling bucket 7 due to unavoidable shaking of the detection device; and secondly, to facilitate internal cleaning and maintenance of the L-shaped tube 9 after long-term use by opening the sealing cap 25. The other end of the tube, which extends out of the sampling bucket 7 wall, is threadedly connected to a water-permeable cap 26. The function of the water-permeable cap 26 is to prevent large particles of debris from entering the L-shaped tube 9 and causing blockage, thus preventing any impact on the water sample collection operation of the L-shaped tube 9.

[0031] The usage method of this embodiment is as follows: When it is necessary to conduct detection operations on the water area around the water conservancy project, the user first needs to drive the detection boat 1 to the designated water area, and then start the motor 24 to drive the take-up roller 2 to rotate, and submerge the detection device installed on the traction rope of the take-up roller 2 into the water. When the water passes through the geotextile 6 and enters the detection range of the water pressure sensor 5, the water pressure sensor 5 will generate a pressure signal. The user can calculate the depth reached by the detection device by the pressure signal transmitted back to the water surface, thereby obtaining the water level depth information of the measured water area. When the user needs to collect water samples from a water area at a specific depth, the user can open the electrically controlled water valve, and the water will flow into the sampling bucket 7 through the L-shaped tube 9. After the appropriate time is reached, the user can close the electrically controlled water valve in the L-shaped tube 9, thus sealing some of the water inside the L-shaped tube 9 and completing the water sample collection. As the detection device continues to sink until the conical drill bit 12 on the detection device contacts the riverbed, the user can adjust the motor 27 to drive the conical drill bit 12 to rotate deeper into the riverbed. During this process, the user can open the electrically controlled butterfly valve to bring the silt from the bottom of the riverbed into the sampling hole 13. The volume change in the sampling hole 13 will naturally push the one-way valve 16 to discharge air. After the calculated time is reached, the electrically controlled butterfly valve is closed to return to the locked state, and some of the silt is trapped in the sampling hole 13, thus completing the silt sampling.

[0032] The water pressure sensor 5, solenoid water valve 10, electrically controlled butterfly valve 14, motor 1 27, and motor 2 24 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the water pressure sensor 5, solenoid water valve 10, electrically controlled butterfly valve 14, motor 1 27, and motor 2 24 will not be explained in detail.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] Although embodiments of the present invention have been shown and described, the scope of the present invention will be defined by the appended claims and their equivalents for those skilled in the art.
