[0002] Buildings and structures in water conservancy projects (such as dams, bridges, gates, etc.) need to be frequently evaluated for structural stability, and vibrating string signal acquisition equipment is a special device for monitoring and collecting vibration signals. It is usually used to measure and analyze vibration conditions in structures, machinery or environments. Therefore, vibrating string signal acquisition equipment has important application value in water conservancy projects and can provide key data and information to help engineers and researchers monitor water vibration conditions, evaluate structural stability, and warn of potential problems, thereby ensuring the safe operation of water conservancy projects; however, there will be various interference sources in the water conservancy project environment, such as the impact of water flow, other vibrations, etc. on the structure, which will cause errors in the data collected by the vibrating string signal acquisition equipment and affect subsequent data analysis and processing; at the same time, the energy consumption of the vibrating string signal acquisition equipment itself is very large, and there is usually a lack of power supply in the water conservancy project environment, which makes the equipment unable to operate and affects signal acquisition. Utility Model Content

[0003] 1. Technical issues to be solved

[0004] In view of the limitations of existing vibrating string signal acquisition equipment, the purpose of the utility model is to provide a vibrating string signal acquisition equipment for water utilization, which solves the problem of lack of power supply and limited equipment operation of vibrating string signal acquisition equipment in water conservancy projects by setting a vibration isolation device and a rotating device; at the same time, it solves the problem that the vibrating string signal acquisition equipment is easily disturbed by water flow or other vibrations during the signal acquisition process, thereby affecting the accuracy of information acquisition.

[0005] (II) Technical solution

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water utilization vibrating string signal collection device, including a vibration reduction device, a vibrating string collector is arranged inside the vibration reduction device, the vibration reduction device is designed as a triangular prism, and the surfaces of its two waists are provided with spiral concave patterns, and rotating devices are fixed on the two waists of the vibration reduction device, and the rotating devices include two symmetrically arranged propellers, and the surfaces of the propellers are provided with spiral convex patterns. The inner walls of the two waists of the vibration reduction device are fixedly connected with rubber vibration isolation pads, and the vibration reduction device is arranged in a triangular prism shape, and the bottom edge can be attached to the water conservancy structure, and the vibrating string collector is arranged inside the vibration reduction device, and its bottom is fixed on the bottom inner wall of the vibration reduction device, but its surroundings do not contact the inner wall of the vibration reduction device, that is, a gap is reserved between the remaining part of the vibrating string collector outside the bottom and the vibration reduction device to facilitate data collection.

[0007] The two sides of the triangular prism can contact the water flow. When the water flows through the two sides, the spiral concave patterns set on the surface will guide the water flow so that it can flow along a spiral trajectory. At the same time, it increases the contact area of ​​the water flow and helps reduce the flow rate of the water flow, thereby effectively reducing the interference of the water flow on the vibrating string collector.

[0008] The rubber isolation pads fixed on the inner walls of both waists help to isolate the additional vibrations in the water conservancy environment, thereby reducing the interference of vibration on the vibrating string collector and improving the accuracy of information collection.

[0009] Preferably, the rotating device also includes two symmetrically arranged support rods and a movable rod connecting the two support rods, both ends of the movable rod pass through the two support rods and extend to the outside of the support rods, rotating devices are fixed on both waists of the vibration damping device, and the two rotating devices are symmetrically fixed on the two waists of the triangular prism, and the support rods are respectively arranged on both sides of the two waists for supporting the movable rods, and the movable rods are symmetrically arranged on both sides of the triangular prism.

[0010] Preferably, the propellers are symmetrically fixed on the movable rod and arranged on the inner side of the support rod. Each propeller is provided with four spiral blades. The propellers can contact the water flow. When the water flows through, the impact force of the water flow can drive the propellers to rotate, and the propellers then drive the movable rods to rotate. The entire rotating device enters a rotating state due to the impact force of the water flow. The rotation can generate energy, and the generated energy can be provided to the vibrating string collector for use. At the same time, it can also help the vibrating string collector to collect signals more efficiently.

[0011] Furthermore, the surfaces of the four spiral blades are provided with spiral protrusions. When the water flow contacts the spiral blades, the spiral protrusions can change the flow of the water flow, reduce the turbulence and eddy currents generated by the fluid on the blade surface, thereby reducing noise and vibration, effectively reducing the interference of water flow and vibration to the vibrating string collector, and improving the accuracy of signal acquisition.

[0012] Preferably, each support rod is perpendicular to the two waists of the vibration reduction device and is provided with a bearing at the connection with the movable rod. The bearing runs through the support rod. Through the bearing, the entire rotating device can rotate smoothly under the impact of the water flow, thereby generating more efficient energy to provide the required energy supply for the vibrating string collector.

[0013] Preferably, a generator is fixedly connected to the inner wall of the bottom edge of the vibration reduction device, and the generator is electrically connected to the vibrating string collector and the rotating device respectively. When water flows through the rotating device, the impact force of the water flow can drive the propeller to rotate, and the rotation of the propeller then drives the movable rod to rotate. The energy generated by the rotation of the movable rod can then drive the generator to operate, and the generator can then provide electrical energy for the vibrating string collector, charge the power supply of the vibrating string collector, and provide an additional and effective power supply for the vibrating string collector, thereby ensuring that the vibrating string collector will not have problems such as insufficient power supply.

[0014] It should be noted that the water flow impact drives the rotating device to rotate and then provide electrical energy for the vibrating string collector. This is an additional power supply. The vibrating string collector itself also has a power management module, and the water flow impact power generation can help deal with emergencies, thereby avoiding power outages in the vibrating string collector and affecting information collection.

[0016] (1) By designing a vibration reduction device and a rotating device, the influence of water flow and vibration on the device can be effectively reduced, and the interference of water flow on the vibrating string collector can be reduced; at the same time, the energy generated by the rotation of the rotating device can realize the power supply of the vibrating string collector, avoiding the situation where the device lacks power supply, thereby increasing the service life of the device and improving the accuracy of information collection.

[0017] (2) The setting of the rotating device and the propeller can help transmit the vibration signal and enhance the signal collection effect. The rotating device can capture the signal generated by the vibration of the water body and transmit it to the vibrating string collector for collection and processing.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Embodiment 1: Figure 1 As shown, the first specific embodiment of the utility model provides a water utilization vibrating string signal collection device, including a vibration reduction device 1, a vibrating string collector 2 is arranged inside the vibration reduction device 1, the vibration reduction device 1 is a triangular prism design, and the surfaces of both waists are provided with spiral concave patterns, and rotating devices 3 are fixed on both waists of the vibration reduction device 1, such as Figure 2 As shown, the rotating device 3 includes two symmetrically arranged propellers 31, and the surfaces of the propellers 31 are both provided with spiral convex patterns, such as Figure 3 As shown, rubber vibration isolation pads 11 are fixedly connected to the inner wall of the vibration reduction device 1 on all sides. The vibration reduction device 1, together with the setting of the spiral concave patterns on its surface, can effectively reduce the vibration interference of the water flow on the vibrating string collector 2, while the rubber vibration isolation pads 11 can absorb and reduce the interference transmitted to the vibrating string collector 2 by the external vibration, thereby improving the accuracy and stability of information collection by the vibrating string collector 2 and ensuring that the collected vibrating string signal is more accurate and reliable.

[0024] Secondly, the design of the triangular prism and the setting of the spiral raised patterns can increase the structural stability of the overall structure of the vibration reduction device 1, so that it can maintain balance and stability in the water flow and reduce the swing and shaking caused by changes in the water flow and the external environment.

[0025] In addition, the spiral raised pattern of the propeller 31 in the rotating device 3 can improve the energy conversion efficiency between the water flow and the propeller 31, improve the efficiency of the water flow driving the rotating device to generate mechanical energy, help realize the power supply of the vibrating string collector 2, and improve the accuracy of information collection and the service life of the equipment.

[0026] like Figure 2 As shown, the rotating device 3 also includes two symmetrically arranged support rods 32 and a movable rod 33 connecting the two support rods 32. Both ends of the movable rod 33 pass through the two support rods 32 and extend to the outside of the support rods 32. The arrangement of the support rods 32 can provide additional support and stability, so that the rotating device 3 is more solid and stable during operation, and the deformation or displacement caused by vibration or external force is reduced; in addition, the movable rod 33 connects the two support rods 32, which can effectively balance and disperse the load and stress borne by the rotating device 3, reduce the possibility of local stress concentration, and is conducive to extending the service life of the equipment, ensuring the stable and effective operation of the device, thereby ensuring the accuracy and effectiveness of information collection.

[0027] like Figure 2 As shown, the propeller 31 is symmetrically fixed on the movable rod 33 and arranged on the inner side of the support rod 32. Each propeller 31 is provided with four spiral blades. The four spiral blades are provided to increase the driving force of the water flow on the propeller 31, thereby improving the propulsion and efficiency of the rotating device 3. The multiple blades can make fuller use of the kinetic energy of the water flow and convert it into mechanical energy, thereby ensuring the power supply to the vibrating string collector 2, so as to ensure the smooth operation of the vibrating string collector 2 and the real-time and accuracy of information collection; in addition, the four spiral blades can balance the load effect of the water flow on the rotating device 3, reduce the vibration and swing caused by imbalance, help improve the stability and reliability of the equipment, and reduce the influence of unnecessary movement on signal collection; and by providing the propeller 31, the flow direction and flow rate of the water flow can be better controlled.

[0028] Furthermore, the design of the spiral protrusion can increase the surface area of ​​the spiral blade, thereby increasing the contact area between the spiral blade and the water flow and improving the propulsion force. When the water flows through the spiral blade, the spiral protrusion can push the water flow more effectively, increase the propulsion effect, and thus achieve faster movement or stronger thrust; in addition, it can also reduce energy consumption and extend battery life.

[0029] Furthermore, the propulsion force generated by the rotation of the propeller 31 can help collect information more effectively.

[0030] The spiral protrusions can also change the flow state of water passing through the spiral blades, reduce turbulence, and lower water resistance, thereby improving the efficiency of the rotating device, and further being able to provide a more sufficient power supply for the vibrating string collector 2.

[0031] Furthermore, the shape and layout of the spiral protrusions can reduce the eddies and turbulence generated when water flows through the spiral blades, greatly reducing vibration and noise, reducing interference with the vibrating string collector 2, and improving the stability and accuracy of information.

[0032] like Figure 1-Figure 3 As shown, each support rod 32 is perpendicular to the two sides of the vibration reduction device 1 and is provided with a bearing 34 at the connection with the movable rod 33. The bearing 34 runs through the support rod 32. The existence of the bearing 34 can make the connection between the support rod 32 and the movable rod 33 smoother, reduce the friction and wear between the support rod 32 and the movable rod 33 when moving, and extend the service life.

[0033] like Figure 1 and Figure 3As shown, a generator 12 is fixedly connected to the inner wall of the bottom edge of the vibration reduction device 1. The generator 12 is electrically connected to the vibrating string collector 1 and the rotating device 3 respectively. The generator 12 can generate electrical energy through the movement of the rotating device 3 to provide power supply for the vibrating string collector 2, thereby helping the vibrating string collector 2 to collect information more stably and accurately.

[0034] Working principle: When in use, the bottom of the vibration reduction device 1 is fixed on the surface of the water conservancy project structure. When the water flows through and contacts the vibration reduction device 1, the spiral grooves on the two waists of the vibration reduction device 1 will guide the water flow, so that the water flow flows along the spiral trajectory, increasing the contact surface while reducing the water flow velocity. The influence of the water flow on the vibration reduction device 1 will be greatly reduced. At the same time, the rubber isolation pads 11 on the inner walls of the two waists will help isolate the vibration caused by the water flow, and at the same time isolate the influence of other vibration sources. At the same time, the water flow flowing through the rotating device 3 contacts the propeller 31, and is affected by the spiral raised patterns on the surface of the propeller 31. The turbulence and eddy current formed by the water flow on the blade surface are effectively reduced, thereby reducing noise and vibration. At the same time, the impact force of the water flow prompts the propeller 31 to rotate, and the rotation of the propeller 31 will drive the movable rod 33 to rotate, and the energy generated by the rotation of the movable rod 33 is transmitted to the generator 12. The operation of the generator 12 converts kinetic energy into electrical energy to provide power supply for the vibrating string collector 2. The vibrating string collector 2 collects and analyzes the information, and then provides real-time feedback.
