[0028] A hydroelectric generator set is a device that converts water energy into electrical energy and is widely used in various hydroelectric power stations. The operation of a hydroelectric generator set depends on the flow and pressure of water, which directly affect the output power and efficiency of the generator set. Water condition detection is crucial to the normal operation and efficiency of a hydroelectric generator set. Water condition detection is a key link in ensuring the safe and efficient operation of a hydroelectric power generation system. By real-time monitoring of the hydrological parameters of water sources such as reservoirs and rivers, important information such as water level, flow, flow rate, and water quality can be obtained. Existing water condition detection devices only have a water level gauge installed in the water condition monitoring chamber for detection. This results in relatively simple monitoring data and is unable to conduct comprehensive monitoring of water conditions at different depths on the water surface and underwater.

[0029] In order to solve the above problems, the present invention proposes a water condition detection and early warning device 1000 for a hydroelectric generator, including a foundation pile 1, a water quality detector 2 and a control component 3, the foundation pile 1 is extended in the vertical direction; the water quality detector 2 includes at least two, and each water quality detector 2 is spaced apart on the foundation pile 1 in the vertical direction; the control component 3 is electrically connected to the water quality detector 2, and the control component 3 includes a controller, a data conversion module and a data transmission module. The controller and the data conversion module are electrically connected to the water quality detector 2 and the controller, and the data transmission module is electrically connected to the controller and is connected to the remote terminal for communication, so as to transmit the detection results of the water quality detector 2 to the terminal.

[0030] The technical solution of the present invention is to set at least two water quality detectors 2 on the foundation pile 1, and each water quality detector 2 is set at intervals along the extension direction of the foundation pile 1, and each water quality detector 2 is used to detect the water quality conditions at different depths, and the detection results of the water quality detector 2 are received and processed by the control component 3, and are remotely transmitted to the display terminal through the data conversion module and the data transmission module, so that the detection personnel can timely understand the water quality conditions at the hydroelectric generator set and deal with them accordingly, thereby ensuring the normal operation of the hydroelectric generator set.

[0031] In an optional embodiment, in order to facilitate the adjustment of the installation position of the water quality detector 2, the water quality detector 2 is detachably connected to the foundation pile 1. In the actual design process, the water quality detector 2 can be directly mounted on the foundation pile 1 and locked and fixed by bolts or screws or other fasteners, or the water quality detector 2 can be connected to the mounting structure by installing a flange or other mounting structure on the foundation pile 1 and fixing it with a fastener, thereby achieving the installation and fixation of the water quality detector 2. Both connection methods can achieve the installation of the water quality detector 2, and the detachable connection method allows the installation height of the water quality detector 2 on the foundation pile 1 to be adjusted according to the detection needs during the actual detection process, thereby achieving the effect of detecting water flows at different depths. In addition, two water quality detectors 2 can be set at the same height of the foundation pile 1 for detection to ensure the reliability of the detection results. The specific selection can be made according to actual needs.

[0032] Furthermore, to ensure the effectiveness of water quality testing, the water quality detector 2 includes a pH sensor, a turbidity sensor, a conductivity sensor, and a flow sensor. The water quality requirements for hydroelectric generators primarily involve several key indicators to ensure the proper operation and extended service life of the generator set. The pH value of the water should be controlled between 6.5 and 8.5 to prevent corrosion and scaling of the generator set materials. Secondly, the conductivity must be maintained within a reasonable range. Excessively high levels may cause localized corrosion, while excessively low levels may affect cooling efficiency. Furthermore, suspended matter and impurities in the water should be minimized to avoid impacting cooling efficiency or clogging cooling pipes. Controlling dissolved oxygen is also crucial. Excessively high levels can cause corrosion, while excessively low levels can affect water quality stability. For hydroelectric power generation, especially cooling water, the suspended matter particle size should be less than 0.15 mm, and the sediment content of particles larger than 0.025 mm should be less than 5% of the total sediment content, with the total sediment content preferably being less than 5 kg / m³. Regular water quality monitoring and treatment are essential to ensure that water quality meets standards. At the same time, a good circulation and filtration system can effectively remove impurities and suspended matter in the water and maintain stable water quality. Various indicators in the water flow are detected by various sensors to understand the quality of the water flow used for the hydropower generator set at any time, thereby ensuring the normal operation of the hydropower generator set and extending the service life of the hydropower generator set as much as possible.

[0033] In an optional embodiment, in order to facilitate the detection personnel to understand the results of the water quality detection in a timely manner, the water situation detection and early warning device 1000 for the hydroelectric generator also includes an alarm component, and the alarm component is electrically connected to the control component 3. During the design process, the threshold values ​​of various indicators of water flow detection can be preset in the control component 3. When the detection result of the water quality detector 2 exceeds the preset threshold value, the alarm component is controlled by the controller to issue an early warning to remind the detection personnel to take corresponding measures in time. Optionally, the alarm component can be directly set around the pile 1 to remind the detection personnel in time through the sound and light alarm device. The alarm component can also be set around the display terminal so that the operator can understand which water flow detection data is abnormal through the display terminal in time after receiving the warning reminder, and take corresponding measures to ensure the normal operation of the hydroelectric generator set.

[0034] In an optional embodiment, to facilitate installation of the water condition detection and warning device 1000 for a hydroelectric generator at the bottom of a water flow, the water condition detection and warning device 1000 for a hydroelectric generator further includes a fixing member 4 connected to the bottom end of the foundation pile 1. When the water condition detection and warning device 1000 for a hydroelectric generator needs to be installed at the bottom of a water flow to detect the water quality at the bottom of a riverbed or reservoir, the fixing member 4 is inserted into the riverbed so that the water condition detection and warning device 1000 for a hydroelectric generator can be fixed to the bottom of the water flow. The fixing member 4 is connected to the bottom of the foundation pile 1 and is detachably connected to the foundation pile 1. For example, the fixing member 4 can be spliced ​​with the foundation pile 1 and then connected together using a fixing member 4 such as a screw or bolt. Alternatively, a threaded hole can be provided in the foundation pile 1, and an external thread is provided on the outer periphery of the fixing member 4. The fixing member 4 is screwed into the threaded hole to achieve a fixed connection between the two. The specific method can be selected according to actual needs.

[0035] Furthermore, in order to facilitate the insertion of the fixing member 4 into the riverbed, the fixing member 4 is a conical structure. Figures 1 to 3 , setting the fixing member 4 to a conical structure can make it easier to insert the fixing member 4 into the riverbed. When pressing down to insert, the silt in the riverbed can be squeezed out more effectively, so that the water condition detection and early warning device 1000 for the hydroelectric generator can be firmly fixed to the bottom of the riverbed. Optionally, the shape of the fixing member 4 can be a cone or a pyramid, which can be selected according to actual needs. In addition, the number of fixing members 4 can be one or more. When the number of fixing members 4 is one, the fixing member 4 can be directly connected to the bottom end of the foundation pile 1. When the number of fixing members 4 is multiple, multiple fixing members 4 can be integrated and connected to a mounting seat, and then the mounting column is connected to the foundation pile 1 to achieve the connection between multiple fixing members 4 and the foundation pile 1. The specific selection can be made according to the actual use needs and is not specifically limited here.

[0036] In an optional embodiment, in order to facilitate the detection of water conditions at the water surface by the water condition detection and warning device 1000 for a hydroelectric generator, the water condition detection and warning device 1000 for a hydroelectric generator further includes a floating plate 5, which is sleeved on the end of the foundation pile 1 away from the fixing member 4. Figures 1 to 3 The floating plate 5 is connected to the upper end of the foundation pile 1. Optionally, the floating plate 5 can be sleeved on the foundation pile 1, or the floating plate 5 can be fixed to the foundation pile 1 by a connector such as a lasso or a fixing pin. The floating plate 5 has buoyancy so that the floating plate 5 can float on the water surface and can drive the foundation pile 1 to float in the water to prevent the foundation pile 1 from sinking to the bottom of the water. The control component 3 is arranged above the floating plate 5 and is arranged in a waterproof shell. The waterproof treatment is done to prevent water from seeping into the control component 3 and causing faults such as short circuits, thereby ensuring the reliability of the water condition detection and early warning device 1000 for a hydroelectric generator.

[0037] In an optional embodiment, to power the water condition detection and warning device 1000 for a hydroelectric generator, the water condition detection and warning device 1000 for a hydroelectric generator further includes a solar panel 6, which is disposed above the control assembly 3 and electrically connected to the water quality detector 2 and the control assembly 3. By disposing the solar panel 6 above the floating plate 5 to convert solar energy into electrical energy to continuously power the water quality detector 2 and the control assembly 3, there is no need to add an additional power supply line to the water condition detection and warning device 1000 for a hydroelectric generator. Furthermore, a battery structure can be added to store some of the electrical energy generated by the solar panel 6. At night or in rainy weather, when power generation is low, the battery can be used to provide power to support the normal operation of the water condition detection and warning device 1000 for a hydroelectric generator. In addition to generating electricity, the solar panel 6 can also be used to shade and protect the control assembly 3 below from rain, thereby minimizing interference and damage to the control assembly 3 from the external natural environment, thereby extending the service life of the control assembly 3.

[0038] In an optional embodiment, in order to protect the water quality detector 2, the water condition detection and early warning device 1000 for a hydroelectric generator further includes a protective shell 7, which is arranged around the periphery of the foundation pile 1, and the water quality detector 2 is arranged in the cavity of the protective shell 7. During the actual detection process, there may be some debris of different sizes and aquatic plants and animals in the water. In order to prevent some larger interference objects from touching the water quality detector 2 and affecting the detection results of the water condition detection and early warning device 1000 for a hydroelectric generator, a protective shell 7 is provided on the periphery of the water quality detector 2. The protective shell 7 is provided with a plurality of filter holes to facilitate water circulation, so that the water quality detector 2 can detect the water quality. This not only ensures the detection effect of the water quality detector 2, but also blocks some larger interference objects outside the protective shell 7, protects the water quality detector 2 inside the cavity, and extends the service life of the water quality monitor.

[0039] Furthermore, in order to facilitate the installation and removal of the protective shell 7, the protective shell 7 includes a cylinder 71 and a cover 72. The cylinder 71 is sleeved on the foundation pile 1, and the cover 72 passes through the foundation pile 1 and covers one side of the cylinder 71. Figure 1 and Figure 3 In this embodiment, the protective shell 7 is a cylindrical hollow body 71. One end of the body 71 is formed with an opening in the axial direction, and the other end is provided with a limiting hole. This allows the operator to easily fit the body 71 onto the pile 1 along the end with the opening. After the pile 1 passes through the body 71, a limiting portion on the pile 1 abuts against the end of the body 71 with the limiting hole, thereby limiting the body 71 from further axial movement along the pile 1. Alternatively, the limiting hole may be a stepped hole. By engaging the limiting portion within the stepped hole, radial movement of the body 71 along the pile 1 can be prevented. A cover 72 is then screwed onto the body 71 to seal the opening, thereby securing the protective shell 7. In another alternative embodiment, the protective shell 7 may have a double-door structure. The protective shell 7 is configured as two semi-cylindrical shells. During installation, the two shells are joined together to enclose the periphery of the pile 1 and secured with screws or other fasteners 4. The protective shell 7 can also be installed and fixed. The specific shape can be selected according to actual needs. The above description is only an exemplary embodiment of the present invention and does not limit the scope of the patent of the present invention. All equivalent structural transformations made based on the technical concept of the present invention and the contents of the present invention specification and drawings, or direct or indirect application in other related technical fields are included in the scope of patent protection of the present invention.
