[0002] Water conservancy and hydropower projects are comprehensive projects that utilize water energy resources for power generation, flood control, irrigation, water supply, shipping, and water environment governance. With the rapid development of the economic society, the energy demand continues to grow. As a clean and renewable energy form, hydropower is of great significance for optimizing the energy structure and reducing greenhouse gas emissions. Through scientific planning and careful construction, water conservancy and hydropower projects can effectively regulate the distribution of water resources and alleviate the problem of water resource shortage. During the process of maintaining the normal operation of water conservancy and hydropower projects, the water level parameter is an important monitoring index, which can reflect the water storage capacity, flood peak regulation ability, etc. of water conservancy and hydropower projects. Through the detection of the water level, the water storage situation of water conservancy projects can be reflected in real time.
[0003] Deficiencies of the prior art: Existing detection devices usually use sensing devices such as radar and ultrasonic waves to detect the water surface height. However, in waters with a large number of aquatic organisms, there will be residues of algae, leaves, etc. on the surface. Therefore, with the flow of water, they will move under the detection device, causing the residues such as algae and leaves to block the water surface, resulting in deviation of the detection data of the detection device and affecting the accuracy of the device for water level detection. Content of the Utility Model
[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a detection device for water conservancy and hydropower engineering to solve the problem that the detection data of the sensing device may be deviated by residues such as algae and leaves covering the water surface in the existing water level detection device in the above-mentioned background technique, which affects the accuracy of the device for water level detection.
[0005] The utility model provides the following technical solution: A detection device for water conservancy and hydropower engineering includes a base and a main rod fixedly connected to the top of the base. Two mounting rings are sleeved on the outer surface of the main rod. A positioning block is fixedly connected to the top of the main rod. One end of each of the two mounting rings is fixedly connected with a telescopic rod. A traction component for increasing the balance of the device is arranged at the top of the positioning block. One end of the telescopic rod far away from the mounting ring is fixedly connected with an adjusting pipe. An isolation component for isolating residues is arranged at the bottom end of the adjusting pipe;
[0006] The isolation component includes an L-shaped connecting rod movably connected to the inner cavity of the adjusting pipe. One end of the L-shaped connecting rod far away from the telescopic rod is fixedly connected with a retaining ring for blocking residues. A floating ring for increasing the buoyancy of the isolation component is fixedly connected to the bottom end of the retaining ring. An isolation net is fixedly connected to the bottom end of the floating ring.
[0007] Preferably, a counterweight ring for increasing the weight of the isolation net is fixedly connected to the bottom end of the isolation net.
[0008] Preferably, a radar water level gauge and a connecting member are installed at one end of the other telescopic rod away from the mounting ring, and the radar water level gauge is located at the central axis above the retaining ring.
[0009] Preferably, the traction assembly includes a winding roller sleeved on the outer surface of the positioning block. A positioning bolt is threadedly connected to the central axis of the winding roller. A traction rope for pulling the telescopic rod is wound around the outer surface of the winding roller, and the traction rope is fixedly connected to the connecting member.
[0010] Preferably, a connecting groove is formed at the bottom end of the winding roller. The connecting groove is sleeved on the outer surface of the positioning block. A positioning hole is formed at the top end of the positioning block. The bottom end of the positioning bolt penetrates through the connecting groove and is threadedly connected to the inner cavity of the positioning hole.
[0011] Preferably, a bracket is fixedly connected to the main rod, and a solar panel for supplying power to the radar water level gauge is fixedly installed at the top end of the bracket.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. The utility model isolates residues such as algae and leaves on the water surface through the isolation component. When using the device to detect the water level, first place the isolation component in the water area to be detected. An area for detection is isolated through the retaining ring, and the retaining ring floats on the water surface through the floating ring at the bottom end. When residues such as algae and leaves on the water surface float along with the water flow, the surrounding residues are blocked outside through the retaining ring, and at the same time, the sundries in the water are isolated through the isolation net at the bottom end, avoiding the residues from drifting to the lower part of the radar water level gauge and causing deviation in the water level detection data. Since the isolation component floats on the water surface through the floating ring, the isolation component will change according to the change of the water level in the water area, ensuring the accuracy of the water level detection result.
[0014] The utility model increases the stability of the radar water level gauge by providing a traction component. After the device is installed, according to the specific position of the detection water area, adjust the length of the telescopic rod so that the radar water level gauge can be located above the water area. When the extended length of the telescopic rod is relatively long, it may be affected by the surrounding environment and weather and show situations such as shaking or tilting. According to the length of the telescopic rod, pull out a corresponding length of the traction rope and connect it to the connecting member. After the connection is completed, rotate the winding roller to tighten the traction rope, and then rotate the positioning bolt to fix the winding roller on the outer surface of the positioning block. The telescopic rod is pulled by the traction rope to avoid shaking or tilting after long-term use, effectively increasing the stability of the radar water level gauge. Description of the Drawings

Specific embodiments
[0020] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the present utility model. In addition, the forms of the respective structures described in the following embodiments are merely examples, and a detection device for water conservancy and hydropower engineering related to the present utility model is not limited to the respective structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.
[0021] The present utility model provides a detection device for water conservancy and hydropower engineering, as Figure 1 - Figure 4 shown, including a base 1 and a main rod 2 fixedly connected to the top thereof. Two mounting rings 3 are sleeved on the outer surface of the main rod 2. A positioning block 4 is fixedly connected to the top of the main rod 2. One end of each of the two mounting rings 3 is fixedly connected to a telescopic rod 5. A traction assembly 6 for increasing the balance of the device is provided at the top of the positioning block 4. One end of a telescopic rod 5 away from the mounting ring 3 is fixedly connected to an adjusting tube 7. An isolation assembly 8 for isolating residues is provided at the bottom of the adjusting tube 7.
[0022] Further, as Figure 1 and Figure 2As shown in the figure, the isolation component 8 includes an L-shaped connecting rod 81 movably connected to the inner cavity of the adjusting pipe 7. One end of the L-shaped connecting rod 81 away from the telescopic rod 5 is fixedly connected with a retaining ring 82 for blocking residues. The bottom end of the retaining ring 82 is fixedly connected with a floating ring 83 for increasing the buoyancy of the isolation component 8. The bottom end of the floating ring 83 is fixedly connected with an isolation net 84. Place the isolation component 8 on the water surface of the water area to be detected. A detection area is isolated by the retaining ring 82. The retaining ring 82 floats on the water surface through the floating ring 83 at the bottom end, so that the isolation component 8 can float up and down with the change of the water level in the water area, ensuring the accuracy of the water level detection result. When the water surface of the water area starts to flow, algae, leaves and other residues floating on the water surface are isolated outside by the retaining ring 82, avoiding the residues covering the water surface of the detection water area and affecting the accuracy of the detection result.
[0023] Further, as Figure 2 shown, a counterweight ring 85 for increasing the weight of the isolation net 84 is fixedly connected to the bottom end of the isolation net 84. Through the counterweight ring 85, the isolation net 84 can sink into the water to isolate sundries in the water, avoiding the sundries moving into the detection water area and affecting the detection result.
[0024] Further, as Figure 1 、 Figure 2 and Figure 3 shown, a radar water level gauge 9 and a connecting piece 10 are installed at one end of the other telescopic rod 5 away from the mounting ring 3. According to the specific position of the detection water area, adjust the length of the telescopic rod 5 so that the retaining ring 82 and the radar water level gauge 9 are located above the detection water area, and the radar water level gauge 9 is located at the central axis above the retaining ring 82. The detection water area isolated by the retaining ring 82 is detected by the radar water level gauge 9. The radar water level gauge 9 emits high-frequency radar waves, measures the time difference from the emission to the reception of the radar waves, and calculates the water level. Through the isolation component 8, the shielding of the radar waves caused by the residues is effectively avoided, so that the device can realize non-contact measurement, effectively improving the detection accuracy and anti-interference ability, and is applicable to complex environments.
[0025] Further, as Figure 3 and Figure 4 shown, the traction component 6 includes a winding roller 61 sleeved on the outer surface of the positioning block 4. A positioning bolt 62 is threadedly connected to the central axis of the winding roller 61. A traction rope 63 for pulling the telescopic rod 5 is wound around the outer surface of the winding roller 61. The traction rope 63 is fixedly connected to the connecting piece 10.
[0026] Further, as Figure 4As shown in the figure, a connection groove 64 is provided at the bottom end of the winding roller 61. The connection groove 64 is sleeved on the outer surface of the positioning block 4. A positioning hole 11 is provided at the top end of the positioning block 4. The bottom end of the positioning bolt 62 penetrates through the connection groove 64 and is threadedly connected to the inner cavity of the positioning hole 11. When the extended length of the telescopic rod 5 is relatively long, it may be affected by the surrounding environment and weather, resulting in situations such as shaking or tilting. According to the length of the telescopic rod 5, a traction rope 63 of a corresponding length is pulled out and connected to the connecting member 10. After the connection is completed, the winding roller 61 is rotated to tighten the traction rope 63. Then, the positioning bolt 62 is rotated to fix the winding roller 61 on the outer surface of the positioning block 4. The telescopic rod 5 is tractioned by the traction rope 63 to avoid shaking or tilting after long-term use, effectively increasing the stability of the radar water level gauge 9.
[0027] Further, as Figure 1 shown in the figure, a bracket 12 is fixedly connected to the main rod 2. A solar panel 13 that provides electrical energy for the radar water level gauge 9 is fixedly installed at the top end of the bracket 12. The direct current generated by the solar panel 13 is converted into alternating current through an inverter, realizing the conversion of light energy into electrical energy.
[0028] The working principle of the present utility model: First, the device is installed on the shore of the detection water area through the base 1. After the installation is completed, according to the distance between the shore and the detection water area, the length of the telescopic rod 5 is adjusted so that the isolation component 8 and the radar water level gauge 9 are located on the water surface. A detection water area is isolated on the water surface through the retaining ring 82. At the same time, the floating ring 83 is used to make the retaining ring 82 float on the water surface, so that the isolation component 8 can float up and down with the change of the water level of the water area, ensuring the accuracy of the water level detection result. The isolation net 84 at the bottom end of the retaining ring 82 sinks into the water through the counterweight ring 85 to isolate impurities in the water. When the water surface starts to flow, the floating algae, leaves and other residues on the water surface are isolated outside through the retaining ring 82, preventing the residues from covering the water surface of the detection water area and affecting the accuracy of the detection result. The radar water level gauge 9 is located above the retaining ring 82. According to the position of the radar water level gauge 9, a traction rope 63 of a corresponding length is pulled out and connected to the connecting member 10. After the connection is completed, the winding roller 61 is rotated to tighten the traction rope 63. Then, the positioning bolt 62 is rotated to fix the winding roller 61 on the outer surface of the positioning block 4. The telescopic rod 5 is tractioned by the traction rope 63 to avoid the radar water level gauge 9 shaking or tilting due to the influence of the surrounding environment and weather, effectively increasing the stability of the radar water level gauge 9. After the device is installed, the detection water area isolated by the retaining ring 82 is detected by the radar water level gauge 9. The radar water level gauge 9 emits high-frequency radar waves, measures the time difference from the emission to the reception of the radar waves, and calculates the water level, enabling the device to achieve non-contact measurement, effectively increasing the detection accuracy and anti-interference ability.
