Description

Technical Field

[0001] This utility model relates to the field of mussel cleaning technology in hydropower station pipelines, specifically to a sterilization device and a hydropower station system. Background Technology

[0002] The golden mussel, scientifically known as *Mussela maculata*, is a freshwater mussel native to Asia. It is mainly distributed in rivers, lakes, and reservoirs in the Yangtze, Yellow, Pearl, Huai, and Haihe River basins. Golden mussels have an extremely high reproductive capacity and cause significant damage. Their strong adhesion can lead to severe blockages in the water pipelines of hydroelectric power station units, affecting the safe and stable operation of these units. The Itaipu Hydroelectric Power Station was forced to shut down for maintenance due to a golden mussel invasion.

[0003] Regularly cleaning mussels from the water pipelines of hydropower stations is a crucial step in ensuring the safe and stable operation of the hydropower station units. Traditional mussel cleaning methods typically involve mechanical and manual cleaning, which involves first draining the water from the pipelines to allow the mussels to dehydrate and die naturally, and then using manual labor or auxiliary machinery (such as pressurized water guns) to clean and scrape them off. However, this cleaning method is labor-intensive, costly, and time-consuming, affecting the normal operation of the hydropower station. Utility Model Content

[0004] In view of this, the present invention provides a sterilization device and a hydropower station system to solve the problems of high labor intensity, high cost and long time consumption in cleaning mussels in existing hydropower station pipelines.

[0005] In a first aspect, this utility model provides a sterilization device for removing mussels from the water pipeline of a hydropower station. The sterilization device includes a bacterial solution dissolving tank, a transmission pipeline, and a pressure pump. The bacterial solution dissolving tank is adapted to carry sterilization liquid. One end of the transmission pipeline is connected to the bacterial solution dissolving tank, and the other end of the transmission pipeline is adapted to be connected to the water pipeline of the hydropower station. The pressure pump is installed on the transmission pipeline.

[0006] The sterilization device of this invention uses a pressure pump to drive the sterilization solution from the bacterial solution dissolution tank to the transmission pipeline, and then into the water pipeline of the hydropower station. The sterilization solution eliminates the golden mussels attached to the water pipeline of the hydropower station, thereby achieving the purpose of cleaning the water pipeline of the hydropower station. Compared with the existing manual and mechanical cleaning methods, the cleaning method of this invention is more efficient, labor-saving, and time-saving, ensuring the normal operation of the hydropower station.

[0007] In one optional embodiment, the sterilization apparatus further includes a compound storage tank connected to the bacterial solution dissolving tank. The compound storage tank can store a certain amount of compound, and water is injected into the bacterial solution dissolving tank. Simultaneously, the compound storage tank provides the compound to the bacterial solution dissolving tank, and the compound dissolves in water to form a sterilization solution.

[0008] In one alternative embodiment, the compound storage tank is positioned above the bacterial solution dissolution tank, allowing the compound in the storage tank to fall into the dissolution tank by gravity.

[0009] In one optional embodiment, the sterilization device further includes a control valve disposed on the transmission pipeline. During normal operation of the hydropower station, the control valve is closed, disconnecting the transmission pipeline and preventing the flow of sterilizing solution. When disinfection of the hydropower station's water pipeline is required, the control valve is opened, reconnecting the transmission pipeline. At this time, the sterilizing solution can flow through the transmission pipeline into the hydropower station's water pipeline, thus cleaning the mussels within the pipeline.

[0010] In one optional embodiment, the sterilization apparatus further includes a motor connected to the pressure pump. The motor drives the pressure pump to ensure the proper functioning of the entire sterilization apparatus.

[0011] In one optional embodiment, the sterilization device further includes a control unit connected to the motor and the control valve to control the opening of the motor and the control valve at preset times. When cleaning of the hydropower station's water pipeline is required, the control unit can automatically control the opening of the motor and the control valve, thereby automatically and periodically cleaning the mussels in the hydropower station's water pipeline, achieving efficient cleaning.

[0012] Secondly, this utility model provides a hydropower station system, including a hydropower station water pipeline and a sterilization device of this utility model, wherein the other end of the transmission pipeline of the sterilization device is connected to the hydropower station water pipeline.

[0013] In one optional embodiment, the hydropower station system further includes a sterilization bypass pipeline, one end of which is connected to the hydropower station's water pipeline, and the other end of which is connected to the other end of the transmission pipeline. The added sterilization bypass pipeline does not affect the normal operation of the hydropower station, and can also connect to a sterilization device when cleaning the hydropower station's water pipeline is required, achieving the disinfection and sterilization of the mussels within the water pipeline.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] The following is combined Figure 1 and Figure 2 The following describes embodiments of the present invention.

[0021] According to an embodiment of the present invention, a sterilization device is provided, comprising a bacterial solution dissolving tank 1, a transmission pipeline 2, and a pressure pump 3. The bacterial solution dissolving tank 1 is adapted to carry chlorine water, one end of the transmission pipeline 2 is connected to the bacterial solution dissolving tank 1, the other end of the transmission pipeline 2 is adapted to be connected to a water pipeline of a hydropower station, and the pressure pump 3 is installed on the transmission pipeline 2.

[0022] The sterilization device of this utility model uses a pressure pump 3 to drive the sterilization liquid from the bacterial solution dissolution tank 1 to the transmission pipeline 2, and then into the water pipeline of the hydropower station through the transmission pipeline 2. The sterilization liquid eliminates the golden mussels attached to the water pipeline of the hydropower station, thereby achieving the purpose of cleaning the water pipeline of the hydropower station. Compared with the existing manual and mechanical cleaning methods, the cleaning method of this utility model is more efficient, labor-saving, and time-saving, ensuring the normal operation of the hydropower station.

[0023] It should be noted that the sterilizing solution can be any solution capable of sterilizing mussels, such as chlorine water or ozone water. In this embodiment, the sterilizing solution is chlorine water.

[0024] The bacterial solution dissolving tank 1 is used to store a certain capacity of sterilization solution to provide sterilization solution for the cleaning of water pipelines in hydropower stations in real time.

[0025] Since sterilization solutions typically have a pungent odor and are volatile, the bacterial solution dissolution tank 1 is preferably configured as a closed tank to reduce the environmental impact of the sterilization solution's evaporation.

[0026] The transmission pipeline 2 can be a metal pipeline or a flexible plastic pipeline. In this embodiment, the transmission pipeline 2 is set as a metal pipeline to extend its service life.

[0027] In terms of specific connection, the wall of the bacterial solution dissolving tank 1 is provided with a through hole, one end of the transmission pipe 2 is inserted into the through hole and communicates with the inside of the bacterial solution dissolving tank 1, and the outer wall of the transmission pipe 2 and the inner wall of the through hole are sealed to prevent leakage of sterilization solution.

[0028] The pressure pump 3 is used to increase the power of the flow of the entire sterilization solution. It is a well-known component in the art and will not be described in detail here.

[0029] In addition to the above-described configuration, the sterilization apparatus of this embodiment also includes a compound storage tank 4, which is connected to a bacterial solution dissolving tank 1. The compound storage tank 4 can store a certain amount of compound. Water is injected into the bacterial solution dissolving tank 1, and the compound storage tank 4 provides the compound to the bacterial solution dissolving tank 1. The compound dissolves in water to form a sterilization solution.

[0030] Specifically, the compound storage tank 4 can store substances such as chlorine tablets, chlorine gas, or ozone, depending on the sterilization requirements.

[0031] Similarly, the compound storage tank 4 is preferably configured as a sealed tank to reduce the environmental impact of compound volatilization while ensuring compound performance.

[0032] The compound storage tank 4 and the bacterial solution dissolving tank 1 can be connected by a pipe. The compound storage tank 4 is located above the bacterial solution dissolving tank 1, so that the compound in the compound storage tank 4 can fall into the bacterial solution dissolving tank 1 by gravity.

[0033] In addition, the sterilization device also includes a control valve 5, which is installed on the transmission pipeline 2. The control valve 5 can control the opening and closing of the transmission pipeline 2. During normal operation of the hydropower station, the control valve 5 is closed, disconnecting the transmission pipeline 2, and no sterilization solution flows. When it is necessary to disinfect the hydropower station's water pipeline, the control valve 5 is opened, connecting the transmission pipeline 2. At this time, the sterilization solution can flow through the transmission pipeline 2 into the hydropower station's water pipeline to clean the mussels inside the hydropower station's water pipeline.

[0034] In this embodiment, the sterilization device also includes a motor 6, which is connected to a pressure pump 3. The motor 6 drives the pressure pump 3 to ensure the normal operation of the entire sterilization device.

[0035] It is understood that the types and models of control valve 5 and motor 6 can be selected in various ways as needed in the existing technology, and will not be described in detail in this embodiment.

[0036] In one optional embodiment, the sterilization device further includes a control unit connected to the motor 6 and the control valve 5 to control the opening of the motor 6 and the control valve 5 at preset times. When cleaning of the hydropower station's water pipeline is required, the control unit can automatically control the opening of the motor 6 and the control valve 5, thereby automatically and periodically cleaning the mussels in the hydropower station's water pipeline, achieving efficient cleaning.

[0037] Specifically, the control unit, motor 6, and control valve 5 can be connected by signal or electrical connection. The control unit signals control the opening or closing of motor 6 and control valve 5 automatically and efficiently.

[0038] It should be noted that the signal transmission and sending of the control unit is existing technology, and will not be described in detail in this embodiment.

[0039] To facilitate understanding of the sterilization device in this embodiment, its usage process is described below.

[0040] When disinfection and sterilization of the hydropower station's water pipelines are required, water is injected into the bacterial solution dissolution tank 1, and the compound in the compound storage tank 4 is added to the bacterial solution dissolution tank 1 to dissolve with water to form a sterilization solution. The control unit automatically controls the motor 6 and the control valve 5 to open. The opening of the control valve 5 connects the transmission pipeline 2, and the motor 6 drives the pressure pump 3 to run. The pressure pump 3 drives the sterilization solution to flow from the bacterial solution dissolution tank 1 to the transmission pipeline 2, and then through the sterilization bypass pipeline to enter the hydropower station's water pipelines. The sterilization solution disinfects the mussels attached to the hydropower station's water pipelines.

[0041] According to an embodiment of the present invention, another aspect provides a hydropower station system, including a hydropower station water pipeline and a sterilization device of the present invention, wherein the other end of the transmission pipeline 2 of the sterilization device is connected to the hydropower station water pipeline.

[0042] The hydropower station system of this utility model is equipped with a sterilization device. When it is necessary to disinfect and sterilize the water pipeline of the hydropower station, the sterilization device can be turned on to introduce sterilization liquid into the water pipeline of the hydropower station, so as to achieve the disinfection and sterilization of the mussels. It is very convenient and efficient.

[0043] In one optional embodiment, the hydropower station system further includes a sterilization bypass pipeline. One end of the sterilization bypass pipeline is connected to the hydropower station's water pipeline, and the other end is connected to the other end of the transmission pipeline 2. The added sterilization bypass pipeline does not affect the normal operation of the hydropower station, and can also connect to the sterilization device when the hydropower station's water pipeline needs to be cleaned, thereby achieving the disinfection and sterilization of the mussels inside the hydropower station's water pipeline.

[0044] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
