Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a testing and inspection platform for water conservancy engineering. Background Technology

[0002] Hydropower generation, also known as water conservancy power generation, is the process of converting the kinetic and potential energy of water flow into electrical energy. A testing and inspection platform for hydropower projects is a device specifically designed for simulating, testing, and evaluating facilities and materials related to hydropower projects.

[0003] A novel experimental simulation device integrating vortex suppression and power generation, disclosed in patent CN106381832B, belongs to the field of hydraulic engineering technology. It includes an upper water tank, a lower water tank, an inlet, a water stabilization mechanism for smoothing the inlet flow, a vortex suppression and power generation mechanism, guide walls, side walls, an angle adjustment device, and a support that can move in three-dimensional space. The upper water tank simulates vortices under different water levels, flow directions, inlet types, and flow rates. Water is drawn from the lower water tank to form a water circulation system. The vortex suppression wheel on the power generation mechanism is driven to rotate by the vortex. The vortex suppression wheel itself blocks the streamlines of the vortex, disperses its velocity distribution, and reduces the velocity gradient, achieving the effect of eliminating vortex suction. The vortex suppression and power generation structure proposed in this patent is rationally designed and highly applicable. It can replace hydraulic structures such as vortex suppression beams to weaken or even isolate cavitation vortices; at the same time, it can efficiently utilize water vortices to drive the vortex suppression wheel to rotate, thereby driving a generator to generate electricity.

[0004] However, the device does not have a structure for adjusting the impact angle and impact volume of the water flow. The impact angle and impact volume of the water flow directly affect the rotational speed of the water turbine. If the impact angle and impact volume of the water flow are not adjusted to a suitable state, it will affect the rotational speed of the water turbine, thereby indirectly affecting the efficiency of hydropower generation.

[0005] To address the aforementioned issues, we have made innovative designs based on the existing structure of testing and inspection platforms used in water conservancy projects. Utility Model Content

[0006] The purpose of this utility model is to provide a testing and inspection platform for water conservancy projects, in order to solve the problem mentioned in the background art that the device does not have a structure for adjusting the impact angle and impact volume of the water flow. The impact angle and impact volume of the water flow directly affect the rotational speed of the water turbine. If the impact angle and impact volume of the water flow are not adjusted to a suitable state, it will affect the rotational speed of the water turbine, thereby indirectly affecting the efficiency of hydropower generation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a testing platform for water conservancy projects, comprising a test platform, a lower water tank fixedly installed at the upper end of the test platform, and a circulating water pump fixedly installed on the outside of the lower water tank; an upper water tank fixedly installed at the upper end of the test platform, and connected to the output end of the circulating water pump via a circulating water pipe; a water flow impact plate rotatably connected to the outside of the lower water tank; a water wheel rotatably connected to the inside of the water flow impact plate via a concentric shaft; a speed sensor fixedly installed on the outside of the water flow impact plate, and the speed sensor and the end of the concentric shaft are distributed in a front-to-back correspondence; an inclination adjustment component disposed at the lower end of the water flow impact plate; and a water flow adjustment component disposed at the bottom of the upper water tank; wherein, the inclination adjustment component is used to adjust the inclination of the water flow impact plate; and the water flow adjustment component is used to adjust the water output of the upper water tank.

[0008] Preferably, the inclination adjustment component includes a support rod, a sliding rod, and slots. The support rod is fixedly installed on the upper end of the test platform, and the sliding rod is slidably connected to the inner side of the support rod. Slots are equidistantly provided on the inner side of the sliding rod.

[0009] Preferably, the tilt adjustment assembly further includes a telescopic spring and a locking rod. The locking rod is connected to the outside of the support rod through the telescopic spring, and the locking rod passes through the inside of the support rod, with the tail end of the locking rod engaged with the inside of the locking groove.

[0010] Preferably, the inclination adjustment component further includes a guide groove and a guide block. The guide groove is formed on the left and right sides of the water flow impact plate, and a guide block is slidably connected to the inner side of the guide groove. The guide block is rotatably connected to the top of the sliding rod.

[0011] Preferably, the water flow regulating component includes a water outlet, a sliding track, a sealing plate, and a rack. The water outlet is located at the top of the upper water tank, and a sliding track is fixedly installed at the bottom of the upper water tank. A sealing plate is slidably connected to the inner side of the sliding track, and a rack is fixedly connected to the side end of the sealing plate.

[0012] Preferably, the water flow regulating component further includes a servo motor and a gear. The servo motor is fixedly installed at the bottom of the upper water tank, and the output end of the servo motor is fixedly connected to the gear, with the outer side of the gear meshing with a rack.

[0013] Preferably, a storage battery is fixedly installed on the upper part of the test platform, and a data analysis module is also fixedly installed on the upper part of the test platform. The storage battery is electrically connected to the speed sensor and the data analysis module.

[0014] Compared with the prior art, the beneficial effect of this utility model is that the testing and inspection platform for water conservancy projects is equipped with: 1. Simulated power generation structure: This structure simulates a waterfall of a certain height by setting up a lower water tank and an upper water tank. When water flows into the water flow from the outlet inside the upper water tank and impacts the inside of the water flow plate, the flowing water will drive the water wheel to rotate. The potential energy generated by the rotation of the water wheel will be converted into electrical energy through the power generation components. The rotation speed of the water wheel can be detected by a speed sensor on the experimental testing platform. The speed detected by the speed sensor will be transmitted to the data analysis module for analysis, thereby simulating and judging the amount of electricity generated. Furthermore, the water flowing into the lower water tank will be pumped back into the upper water tank for reuse via a circulating water pump, thereby saving water resources and improving the sustainability of the experiment. 2. Inclination Adjustment Structure: When it is necessary to adjust the inclination of the water flow impact plate, first pull the locking rod outward to separate the tail end of the locking rod from the locking groove. After the tail end of the locking rod is separated from the locking groove, the sliding rod is in an active state. At this time, sliding the sliding rod upward will allow the guide block to slide along the inner side of the guide groove, so that the sliding rod lifts the tail end of the water flow impact plate, thereby changing the inclination of the water flow impact plate. At this time, the influence of the inclination of the water flow impact plate on the water wheel speed can be analyzed by detecting the speed of the water wheel by the speed sensor. 3. Water flow regulation structure: When the water flow needs to be adjusted, this structure operates a servo motor, which drives a gear to rotate. The rotation of the gear causes the outer meshing rack to move back and forth. The back and forth movement of the rack causes the sealing plate to slide inside the sliding track. The movement of the sealing plate adjusts the water flow rate at the outlet. At this time, the influence of the water flow rate on the water turbine speed can be analyzed by detecting the speed of the water turbine using a speed sensor, thereby improving the power generation efficiency in actual use.

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.

[0018] Please see Figures 1-6 This utility model provides a technical solution: a testing and inspection platform for water conservancy projects, comprising: Example 1: As Figures 1-4 The present invention provides a technical solution: a testing platform for water conservancy engineering, comprising: a test platform 1, with a lower water tank 2 fixedly installed at the upper end of the test platform 1, and a circulating water pump 3 fixedly installed on the outside of the lower water tank 2; an upper water tank 5, fixedly installed at the upper end of the test platform 1, and connected to the output end of the circulating water pump 3 through a circulating water pipe 4; a water flow impact plate 6, rotatably connected to the outside of the lower water tank 2; a water wheel 8, rotatably connected to the inside of the water flow impact plate 6 through a concentric shaft 7; a speed sensor 9, fixedly installed on the outside of the water flow impact plate 6, with the speed sensor 9 and the end of the concentric shaft 7 distributed in a front-to-back correspondence; an inclination adjustment component 10, disposed at the lower end of the water flow impact plate 6; and a water flow adjustment component 11, disposed at the bottom of the upper water tank 5; wherein, the inclination adjustment component 10 is used to adjust the inclination of the water flow impact plate 6; and the water flow adjustment component 11 is used to adjust the water output of the upper water tank 5. The inclination adjustment assembly 10 includes a support rod 1001, a sliding rod 1002, and a slot 1003. The support rod 1001 is fixedly installed on the upper end of the test platform 1, and the sliding rod 1002 is slidably connected to the inner side of the support rod 1001. The slots 1003 are equidistantly opened on the inner side of the sliding rod 1002. The inclination adjustment assembly 10 also includes a telescopic spring 1004 and a locking rod 1005. The locking rod 1005 is connected to the outer side of the support rod 1001 through the telescopic spring 1004, and the locking rod 1005 passes through the inner side of the support rod 1001. The tail end of the locking rod 1005 is engaged with the inner side of the slot 1003. The inclination adjustment assembly 10 also includes a guide groove 1006 and a guide block 1007. The guide groove 1006 is opened on the left and right sides of the water flow impact plate 6, and the guide block 1007 is slidably connected to the inner side of the guide groove 1006. The guide block 1007 is rotatably connected to the top of the sliding rod 1002. This experimental testing platform is designed to scale with a real waterfall. It simulates a waterfall of a certain height by setting up a lower water tank 2 and an upper water tank 5. When water flows into the water flow impact plate 6 through the outlet 1101 inside the upper water tank 5, the flowing water drives the water wheel 8 to rotate. The potential energy generated by the rotation of the water wheel 8 is converted into electrical energy by the power generation component. The rotation speed of the water wheel 8 is detected by the speed sensor 9 on the experimental testing platform. The speed detected by the speed sensor 9 is transmitted to the data analysis module 13 for analysis, thereby simulating and determining the amount of electricity generated. Furthermore, the water flowing into the lower water tank 2 is circulated back into the upper water tank 5 through the circulation pipe 4 by the circulation pump 3. This method achieves water conservation and enhances the sustainability of the experiment. When it is necessary to adjust the tilt of the water flow impact plate 6, first pull the lever 1005 outward to separate the tail end of the lever 1005 from the slot 1003. After the tail end of the lever 1005 is separated from the slot 1003, the sliding rod 1002 is in an active state. At this time, sliding the sliding rod 1002 upward will allow the guide block 1007 to slide along the inner side of the guide groove 1006, so that the sliding rod 1002 will lift the tail end of the water flow impact plate 6, thereby changing the tilt of the water flow impact plate 6. At this time, the influence of the tilt of the water flow impact plate 6 on the rotational speed of the water wheel 8 can be analyzed by detecting the rotational speed of the water wheel 8 through the speed sensor 9.

The sealing plate 1103 is slidably connected to the inner side of the sliding rail 1102, and the rack 1104 is fixedly connected to the side end of the sealing plate 1103. The water flow regulating component 11 also includes a servo motor 1105 and a gear 1106. The servo motor 1105 is fixedly installed at the bottom of the upper water tank 5, and the output end of the servo motor 1105 is fixedly connected to the gear 1106, and the outer side of the gear 1106 meshes with the rack 1104.

The storage battery 12 is electrically connected to the speed sensor 9 and the data analysis module 13. When the water flow needs to be adjusted, this structure operates the servo motor 1105, which drives the gear 1106 to rotate. The rotation of the gear 1106 causes the outer meshing rack 1104 to move back and forth. The back and forth movement of the rack 1104 causes the sealing plate 1103 to slide inside the sliding track 1102. The movement of the sealing plate 1103 adjusts the water flow rate at the outlet 1101. At this time, the influence of the water flow rate on the water turbine 8 can be analyzed by detecting the rotational speed of the water turbine 8 through the speed sensor 9, thereby improving the power generation efficiency in actual use.
