Description

Technical Field

[0001] This utility model relates to the technical field of nuclear power plant waste removal equipment, and more specifically, to a net-type waste suction device and nuclear power plant waste removal equipment. Background Technology

[0002] Currently, the main type of waste removal and cleaning device used in nuclear power plants is a suction pipe and pump. The suction pipe is generally made of plastic or rubber and is directly connected to the pump via a flange. In use, the suction pipe is placed in the water near the waste for suction and cleaning. This device has a simple overall structure and is suitable for relatively simple operating conditions. However, in practical applications, the existing technology has significant shortcomings:

[0003] Difficulty in connecting pipes and nets under complex working conditions: Existing suction equipment has difficulty quickly connecting pipes to the nets that collect waste that has accumulated in them, which affects cleaning efficiency.

[0004] Unable to pump waste to shore in wide bodies of water: In relatively wide bodies of water, ordinary suction devices cannot directly pump waste to shore, and cannot meet the need for quick and effective cleaning of net bag garbage in waters with intercepting nets.

[0005] With the operation of nuclear power plants, outbreaks of marine life or blockages of water intakes by marine debris occur frequently. If the debris in the interception nets is not cleaned in time, it may cause the nuclear power plant to shut down due to cooling source problems, affecting the normal operation of the power plant. Utility Model Content

[0006] The purpose of this utility model is to provide a net-type waste suction device and a nuclear power plant waste suction equipment to solve the technical problems in the prior art, such as the inability to quickly connect the pipe and the net under complex working conditions and the difficulty in suctioning waste to the shore in wide waters, which affect the efficiency of waste removal and the normal operation of the power plant.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] In a first aspect, a net-bag waste suction device is provided, comprising:

[0009] First suction drive component float;

[0010] A first suction drive is disposed on the float of the first suction drive, and the first suction drive is used to provide suction power.

[0011] A main guide tube is connected to the first suction drive component, and the main guide tube is used to extend toward the target waste suction area;

[0012] Multiple mesh suction tubes are arranged sequentially at intervals along the extension direction of the main guide tube. The mesh suction tubes are used to connect the main guide tube and the mesh. A second suction drive is connected between the mesh suction tube and the main guide tube. The mesh suction tube is provided with a mesh connector for detachable connection with the mesh.

[0013] The drain pipe is connected to the first suction drive and the guide pipe. The drain pipe extends toward the waste discharge area and discharges the waste from the guide pipe and the mesh suction pipe under the drive of the suction drive.

[0014] By adopting the above technical solution, the device is equipped with multiple mesh suction pipes arranged sequentially at intervals along the extension direction of the main guide pipe. The mesh suction pipes are equipped with mesh connectors for detachable connection with the mesh. Compared with the existing technology where it is difficult to quickly connect the pipe to the mesh for collecting sludge, the design of multiple mesh suction pipes can increase the opportunity to connect with the mesh, and the mesh connectors facilitate quick connection, thereby enabling faster connection with the mesh and improving the cleaning efficiency.

[0015] The device is equipped with a first suction drive component to provide suction power. A main guide pipe extends towards the target waste suction area, and a discharge pipe extends towards the waste discharge area. Driven by the first suction drive component, waste in the net bag is sucked through the main guide pipe and the net bag suction pipe, and then discharged through the discharge pipe. Unlike ordinary suction devices that cannot directly suck waste from wide bodies of water to the shore, this device, through its reasonable structural design and power drive, can quickly and effectively clean up the waste in the net bag in wide bodies of water with intercepting nets and suck it to the shore, meeting actual waste removal needs.

[0016] Because this device can effectively and promptly clean up debris in the interception net, it can prevent nuclear power plants from shutting down due to cold source problems in the event of marine life outbreaks or blockage of water intakes by marine debris, thus ensuring the normal operation of nuclear power plants.

[0017] In one embodiment, the net connector is a rope or a clamp.

[0018] In one embodiment, the net connector is provided with a connector float that allows the connection between the net connector and the net to float on the water surface.

[0019] In one embodiment, the net bag sewage suction device further includes a plurality of guide pipe floats arranged sequentially along the extension direction of the guide pipe. Each guide pipe float includes a first float block and a second float block that docks with the first float block. A fixing groove is provided between the second float block and the first float block, and the guide pipe passes through the fixing groove.

[0020] In one embodiment, the net-bag sewage suction device further includes a cable arranged along the extension direction of the main guide tube and connected to the main guide tube by a plurality of connecting structures.

[0021] In one embodiment, the net-bag sewage suction device further includes a plurality of sewage pipe floats arranged sequentially along the extension direction of the sewage pipe.

[0022] In one embodiment, a valve is provided between the second suction drive and the mesh suction tube.

[0023] In one embodiment, the first suction drive float is connected to an anchor block, the anchor block is used to sink to a target position on the bottom of the water, and an anchor block connector is connected between the anchor block and the first suction drive.

[0024] In one embodiment, a flange is connected between the main guide pipe and the first suction drive, and a flange is connected between the first suction drive and the float of the first suction drive.

[0025] A connector is provided between the sewage pipe and the first suction drive component.

[0026] Secondly, a nuclear power plant waste removal device is provided, comprising a main body of the nuclear power plant waste removal device and the aforementioned net-bag waste suction device, wherein the main body of the nuclear power plant waste removal device is connected to the net-bag waste suction device.

[0027] By adopting the above technical solution, in addition to the advantages of the net bag sewage suction device of the above embodiment, the nuclear power plant sewage suction equipment of this embodiment also has the advantage of high maintenance efficiency. Attached Figure Description

The specific implementation of this utility model is described in more detail below with reference to specific embodiments:

[0042] like Figures 1 to 3As shown in the figure, an embodiment of the present invention provides a mesh bag for suctioning waste, comprising:

[0043] First suction drive component float 1;

[0044] The first suction drive 2 is disposed on the first suction drive float 1, and the first suction drive 2 is used to provide suction power.

[0045] The guide pipe 3 is connected to the first suction drive component 2, and the guide pipe 3 is used to extend toward the target sewage suction area;

[0046] Multiple net suction tubes 4 are arranged sequentially at intervals along the extension direction of the main guide tube 3. The net suction tubes 4 are used to connect the main guide tube 3 and the net 10. A second suction drive 5 is connected between the net suction tube 4 and the main guide tube 3. The net suction tube 4 is provided with a net connector 41 for detachable connection with the net 10.

[0047] The drain pipe is connected to the first suction drive 2 and the guide pipe 3. The drain pipe is used to extend toward the waste discharge area. Under the drive of the suction drive, the drain pipe discharges the waste from the guide pipe 3 and the net suction pipe 4.

[0048] Specifically, the first suction drive component float 1 refers to the structure that provides buoyancy to the first suction drive component 2 on the water surface, ensuring that the first suction drive component 2 can float stably on the water surface to carry out its work. In this embodiment, the first suction drive component float 1 can be a float.

[0049] The first suction drive component 2 is installed on the first suction drive component float 1. As the core power source, it provides the basic power to suck the sewage from the net bag 10 to the sewage pipe and is the key driving force that enables the entire suction process.

[0050] The main guide pipe 3 is connected to the first suction drive component 2, acting as a conveying channel to transmit power to the target dirt area. Its extension direction determines the suction range that the device can cover. Multiple mesh bag suction pipes 4 are distributed at intervals along the main guide pipe 3. One end is connected to the main guide pipe 3 through the second suction drive component 5, which can perform targeted suction of dirt in the mesh bag 10, enhancing the flexibility and efficiency of suction. The other end is detachably connected to the mesh bag 10 through the mesh bag connector 41, which facilitates quick replacement of mesh bags 10 at different locations according to actual conditions, adapting to various working conditions.

[0051] The sewage pipe is connected to the first suction drive unit 2 and the guide main pipe 3. It is responsible for transporting the sewage collected from the net suction pipe 4 and transported through the guide main pipe 3 to the designated sewage discharge area under the power generated by the first suction drive unit 2, thus completing the entire sewage suction and cleaning process.

[0052] By adopting the above technical solution, the device is provided with multiple net suction pipes 4 arranged sequentially at intervals along the extension direction of the guide pipe 3, and the net suction pipe 4 is provided with a net connector 41 for detachable connection with the net 10. Compared with the existing technology where it is difficult to quickly connect the pipe to the net 10 for collecting dirt, the design of multiple net suction pipes 4 can increase the opportunity to connect with the net 10, and the net connector 41 facilitates quick connection, thereby enabling faster connection with the net 10 and improving the dirt removal efficiency.

[0053] The device is equipped with a first suction drive 2 to provide suction power, and a guide pipe 3 extends towards the target sewage suction area, while a discharge pipe extends towards the sewage discharge area. Driven by the first suction drive 2, sewage can be sucked from the net bag 10 through the guide pipe 3 and the net bag suction pipe 4, and discharged through the discharge pipe. Unlike ordinary suction devices that cannot directly suck sewage from a wide body of water to the shore, this device, through its reasonable structural design and power drive, can quickly and effectively clean the garbage in the net bag 10 in a wide body of water with an intercepting net bag 10, and suck it to the shore, thus meeting actual sewage cleaning needs.

[0054] Because the device can clean up the debris in the interception net 10 in a timely and effective manner, it can prevent the nuclear power plant from shutting down due to cold source problems in the event of marine organism outbreaks or blockage of the water intake by marine foreign objects, thus ensuring the normal operation of the nuclear power plant.

[0055] In one embodiment, the net connector 41 is a rope or a clamp.

[0056] Specifically, the function of the net bag connector 41 is to achieve a detachable connection between the net bag suction pipe 4 and the net bag 10. When the net bag sewage suction device is working, it is necessary to reliably connect the net bag suction pipe 4 and the net bag 10 so that the sewage in the net bag 10 can be sucked out through the suction pipe; when the device is not working or when maintenance or replacement of parts is required, the net bag suction pipe 4 can be easily separated from the net bag 10, so a detachable connection is required.

[0057] Rope connectors are a common and simple type of connecting component. When using a rope connector 41 as the net bag connector, the rope can be tied around the connection point between the net bag suction tube 4 and the net bag 10, using the binding force of the rope to connect the two. The advantages of this method are its low cost and flexibility, adapting to different shapes and sizes of the net bag 10 and the suction tube. For example, when the net bag 10 is made of a soft material or has an irregular surface, the rope can fit and hold it in place well. Furthermore, untying the rope allows for easy separation. However, rope connectors may also have some disadvantages, such as potentially less secure connections than some rigid connectors, and the rope may loosen or slip under prolonged use or when subjected to significant tension.

[0058] A clamp is a rigid connecting component, typically made of metal or other high-strength materials. The working principle of a clamp is to tighten it, firmly holding the connection between the net suction tube 4 and the net 10, thus achieving a secure connection. Compared to rope-like components, clamp connections are more reliable, capable of withstanding greater tensile and compressive forces, and less prone to loosening. Furthermore, clamp installation and removal are relatively convenient, generally accomplished by tightening or loosening bolts or other fasteners on the clamp. For example, when replacing or repairing the net suction tube 4, loosening the clamp allows for quick separation from the net 10. However, clamps may be relatively expensive, and require a higher degree of matching in shape and size between the net 10 and the suction tube.

[0059] By adopting the above technical solution, offering either ropes or clamps as options, flexible solutions are provided for different usage scenarios and needs. If the requirement for connection strength is not particularly high, and cost and operational flexibility are the main considerations, ropes can be chosen; while if a more reliable connection is required, and a relatively higher cost is acceptable, and certain dimensional accuracy requirements for the connection points are met, clamps can be selected. This versatility allows the net-bag waste suction device to better adapt to different working conditions and user needs.

[0060] like Figure 4 As shown, in one embodiment, the net connector 41 is provided with a connector float 42 that allows the connection between the net connector 41 and the net 10 to float on the water surface.

[0061] Specifically, in the scenario of cleaning up contaminants using the intercepting net 10 at a nuclear power plant, if the connection part to the net 10 is submerged in water, it may make the connection operation difficult, as underwater visibility and operability are poor, increasing the difficulty of installing and disassembling the net suction pipe 4 and the net 10. Furthermore, the connection part being submerged for extended periods may be affected by water flow impacts and corrosion, reducing the reliability and lifespan of the connection. Allowing the connection part to float on the water surface effectively solves these problems, improving operational convenience and the stability of the connecting components.

[0062] The main function of the connector float 42 is to provide sufficient buoyancy for the net connector 41, enabling it to overcome its own weight and the weight of the connecting parts and float on the water surface. This allows operators to more easily observe and access the connecting parts for installation, disassembly, or inspection.

[0063] The floating net connector 41 can also play a certain positioning role, making it easier to determine the relative position of the net suction pipe 4 and the net 10, so as to accurately connect the net suction pipe 4 and the net 10, improve docking efficiency, and thus improve the efficiency of the entire cleaning work.

[0064] The connector float 42 prevents the connecting part from being immersed in water for a long time, reducing water corrosion, wear and other damage to the net connector 41, extending the service life of the net connector 41 and related components, and reducing maintenance costs.

[0065] In actual cleaning operations, when the net-type debris suction device is working, the net connector 41 remains near the water surface due to the presence of the connecting float 42. This makes both the initial connection operation and adjustments or checks on the connection status during the cleaning process more convenient. Simultaneously, it reduces the risk of equipment failure due to underwater damage to the connection parts, ensuring the continuity and stability of the cleaning work.

[0066] This design works in conjunction with other parts of the net-bag sewage suction device to achieve the goal of efficient sewage removal. For example, the net-bag suction pipe 4 is connected to the net 10 via the net-bag connector 41, and the connector float 42 ensures that the connection part floats on the water surface, allowing the net-bag suction pipe 4 to better connect with the net 10. Then, under the action of the first suction drive component 2 and other components, the sewage in the net 10 is successfully sucked out and discharged through the sewage pipe, improving the practicality and reliability of the entire device.

[0067] like Figure 5As shown, in one embodiment, the net bag sewage suction device further includes a plurality of guide pipe floats 31 arranged sequentially along the extension direction of the guide pipe 3. Each guide pipe float 31 includes a first float block 311 and a second float block 312 docked with the first float block 311. A fixing groove 313 is provided between the second float block 312 and the first float block 311, and the guide pipe 3 passes through the fixing groove 313.

[0068] The guide pipe 3 is a component in the net-sucking sludge suction device that extends towards the target sludge suction area and transports the sludge sucked up from the net-sucking suction pipe 4. In practical applications, such as when cleaning up sludge in water, to ensure that the guide pipe 3 remains in a suitable position and avoids sinking to the bottom or being displaced or twisted due to water flow or other factors, thus affecting the normal transport of sludge and the overall efficiency of the device, a guide pipe float 31 is provided to allow the guide pipe 3 to float stably near the water surface.

[0069] The guide tube float 31 includes a first float block 311 and a second float block 312. This split design facilitates installation and disassembly. During installation, the first float block 311 and the second float block 312 can be connected from both sides of the guide tube 3 to easily and quickly fix the guide tube 3 inside the float. When maintenance, repair, or replacement of the guide tube 3 is required, the float can be easily disassembled, allowing the guide tube 3 to detach from the float.

[0070] The first float block 311 and the second float block 312 are joined together to form a fixing groove 313, through which the guide pipe 3 is inserted. The design of the fixing groove 313 ensures that the position of the guide pipe 3 in the float is relatively fixed, preventing it from shaking or shifting under the impact of water flow, thus ensuring the stability of the guide pipe 3 during the transportation of waste. At the same time, the shape and size of the fixing groove 313 are adapted to the guide pipe 3, which can both tightly fix the guide pipe 3 and avoid excessive compression or damage to the guide pipe 3.

[0071] Multiple guide pipe floats 31 are arranged sequentially along the extension direction of the guide pipe 3. This arrangement provides multi-point support for the guide pipe 3, ensuring effective buoyancy support and positional fixation over a relatively long distance. Compared to setting only one or a few floats, the arrangement of multiple floats can better adapt to different water flow environments and working conditions, reducing the risk of deformation or damage to the guide pipe 3 due to uneven local stress, and improving the reliability and stability of the entire net-collecting debris suction device.

[0072] The guide pipe float 31 works in conjunction with other components of the net-bag sludge suction device, such as the first suction drive 2 and the net-bag suction pipe 4. The guide pipe float 31 ensures the stable position of the guide pipe 3, enabling the first suction drive 2 to more effectively transport the sludge sucked up by the net-bag suction pipe 4 through the guide pipe 3 to the discharge pipe for final discharge. This ensures the smooth progress of the entire cleaning process and improves the cleaning efficiency and performance of the device.

[0073] Please refer to it again. Figure 3 In one embodiment, the net bag sewage suction device further includes a cable 7, which is arranged along the extension direction of the guide tube 3 and is connected to the guide tube 3 by a plurality of connection structures 71.

[0074] Specifically, when the net-type waste suction device is operating, the main guide pipe 3 is in an aquatic environment and may be affected by various external forces such as water flow and waves. The main purpose of setting up the cable 7 is to enhance the stability and controllability of the main guide pipe 3, preventing it from undergoing large-scale displacement, swaying, or twisting under complex aquatic conditions, thereby ensuring the normal and stable operation of the entire device. Through the constraint and fixing effect of the cable 7, the main guide pipe 3 is kept in a suitable position for effective waste suction and transportation.

[0075] The cable 7 is arranged along the extension direction of the main conduit 3. This arrangement allows the cable 7 to support and constrain the main conduit 3 throughout its length. Being aligned with the extension direction of the main conduit 3 better adapts to the force direction experienced by the main conduit 3 during operation, more effectively dispersing and bearing external forces, and preventing damage to the main conduit 3 or its connecting parts due to excessive localized stress.

[0076] Multiple connecting structures 71 connect the cable 7 to the main conduit 3, playing a crucial role in fixing and connecting the cable 7 to the main conduit 3. The multiple connecting structures 71 ensure a more secure and even connection between the cable 7 and the main conduit 3, preventing stress concentration on the cable 7 at any point and thus connection failure. Simultaneously, the connecting structures 71 facilitate the installation and removal of the cable 7, allowing for convenient operation when maintenance, adjustment, or relocation of the device is required. For example, after the device has finished operating, it may need to be moved to another location; in this case, the cable 7 can be untied by adjusting the connecting structures 71, facilitating the device's movement. Conversely, when redeploying the device, the connecting structures 71 can quickly reconnect the cable 7 to the main conduit 3, restoring the device's stability.

[0077] The installation of cable 7 and connecting structure 71 enhances the reliability and stability of the net-bag sludge suction device in actual operation. In complex aquatic conditions, such as turbulent waters and high waves, cable 7 effectively limits the movement range of the guide pipe 3, ensuring proper connection between the net-bag suction pipe 4 and the net 10, and smooth transport of sludge. This improves cleaning efficiency, reduces malfunctions and maintenance frequency due to device instability, lowers operating costs, and extends the device's service life.

[0078] The cable 7 and connecting structure 71 work in conjunction with other components of the net-bag sludge suction device, such as the guide pipe float 31 and the net-bag suction pipe 4. The guide pipe float 31 provides buoyancy, keeping the guide pipe 3 floating near the water surface, while the cable 7 further constrains and fixes the guide pipe 3. Together, they maintain a stable position and attitude of the guide pipe 3 on the water surface, creating favorable conditions for the net-bag suction pipe 4 to successfully suction sludge from the net bag 10, thus ensuring the efficient operation of the entire device.

[0079] In one embodiment, the net-bag sewage suction device further includes a plurality of sewage pipe floats arranged sequentially along the extension direction of the sewage pipe.

[0080] The discharge pipe is a component of the net-sucking sewage suction device used to discharge sewage from the guide pipe 3 and the net suction pipe 4 to a designated area. In actual water cleanup operations, the discharge pipe needs to transport sewage from the location of the net 10 to the shore or other sewage discharge areas. Since the discharge pipe is in the water, in order to keep it stably in a suitable position and prevent it from sinking, twisting, or deviating from the predetermined discharge path due to its own weight, water flow impact, etc., which would affect the normal discharge of sewage and the working efficiency of the entire device, a discharge pipe float is installed. This allows the discharge pipe to float stably near the water surface, ensuring the smooth progress of the sewage discharge process.

[0081] Multiple buoys are arranged sequentially along the extension direction of the sewage pipe, providing multi-point support. The even distribution of these buoys ensures effective buoyancy support over a considerable length, guaranteeing stable floating throughout the entire extension path. Compared to using only one or a few buoys, this arrangement better adapts to different water flow environments and operating conditions, reducing the risk of deformation or damage due to uneven local stress, and improving the stability and reliability of the sewage pipe.

[0082] The main function of the drain pipe float is to provide buoyancy for the drain pipe, enabling it to overcome its own weight and float on the water surface. This prevents the drain pipe from being damaged by water flow and friction due to sinking to the bottom, thus extending the service life of the drain pipe.

[0083] The arrangement of multiple sewage pipe floats can fix the sewage pipes in a relatively stable position, preventing them from shifting or swaying significantly under the influence of water flow, and ensuring that the sewage pipes can discharge waste along a predetermined path. This is of great significance for ensuring that waste is accurately discharged to the designated area and avoiding pollution to the surrounding environment.

[0084] The presence of the float on the sewage pipe also makes its installation and maintenance more convenient. During installation, the position and height of the sewage pipe can be adjusted using the float, making it easier to connect to other components. During maintenance, because the sewage pipe floats on the water surface, workers can more easily inspect, repair, and replace it.

[0085] The drain pipe float works in conjunction with other components of the net-bag sludge suction device, such as the main guide pipe 3, the net-bag suction pipe 4, and the first suction drive 2. Together with the main guide pipe float 31, it ensures the stability of the pipeline system in the device, enabling the first suction drive 2 to effectively transport the sludge in the net bag 10 through the net-bag suction pipe 4 and the main guide pipe 3 to the drain pipe, and finally discharge it smoothly. This ensures the smooth progress of the entire cleaning process and improves the cleaning efficiency and working performance of the device.

[0086] In one embodiment, a valve 8 is provided between the second suction drive 5 and the net suction tube 4.

[0087] Specifically, the main function of valve 8 is to control the flow of fluid. In the mesh bag suction device, valve 8, located between the second suction drive 5 and the mesh bag suction pipe 4, can control the flow of fluid from the mesh bag suction pipe 4 into the second suction drive 5. When valve 8 is open, fluid can pass through smoothly, allowing the second suction drive 5 to suction and transport the waste in the mesh bag 10; when valve 8 is closed, the flow of fluid is blocked, thereby stopping the suction operation corresponding to the mesh bag suction pipe 4.

[0088] The device may be equipped with multiple mesh suction pipes 4, each with a valve 8 between it and the second suction drive component 5. This allows for independent control of the suction operation of each mesh suction pipe 4. For example, in actual cleaning operations, if the dirt in the mesh bag 10 corresponding to a particular mesh suction pipe 4 has been completely removed, or if that mesh suction pipe 4 malfunctions and requires maintenance, the operation of that mesh suction pipe 4 can be stopped by closing the corresponding valve 8, without affecting the continued cleaning operation of other mesh suction pipes 4. This flexible control method improves the ease of operation and adaptability of the device, enabling precise adjustments to its operation according to different working conditions and needs.

[0089] When the device starts or stops, valve 8 prevents sudden fluid impacts from damaging the second suction drive component 5. For example, during device startup, without the control of valve 8, fluid might enter the second suction drive component 5 with significant impact force, causing damage to internal components. When the device stops, valve 8 prevents fluid backflow, avoiding contaminants flowing back into the mesh bag 10 or other components, thus affecting the normal operation and subsequent use of the device. Furthermore, when abnormal conditions occur in the system, such as excessively high or low pressure, valve 8 can close promptly, cutting off fluid flow and protecting the safety of the entire system.

[0090] By adjusting the opening of valve 8, the flow rate and pressure of the fluid in the mesh suction pipe 4 can also be regulated. Depending on the condition of the mesh 10 and the characteristics of the contaminants, different suction flow rates and pressures may be required to achieve the best cleaning effect. For example, for some thicker contaminants, a larger suction pressure and flow rate may be needed, in which case valve 8 can be opened wider; while for some thinner contaminants, valve 8 can be closed wider to save energy and improve cleaning efficiency. Through this adjustment of flow rate and pressure, the device can better adapt to different cleaning conditions and improve the cleaning effect.

[0091] The valve 8 works in conjunction with other components of the net-bag sewage suction device, such as the first suction drive 2, the guide pipe 3, and the discharge pipe. Together with the first suction drive 2, it controls the entire suction and discharge process of the device, ensuring that sewage is effectively cleaned and discharged according to a predetermined path and method. For example, while the first suction drive 2 provides suction power, proper control of the valve 8 ensures coordinated operation of each net-bag suction pipe 4, improving the overall operating efficiency of the device.

[0092] Please refer to it again. Figure 1 In one embodiment, the first suction drive component float 1 is connected to an anchor block 9, which is used to sink to the target position on the bottom of the water. An anchor block connector 91 is connected between the anchor block 9 and the first suction drive component 2.

[0093] Specifically, the first suction drive component float 1 supports the first suction drive component 2 and is an important part of the entire net bag debris suction device. The main function of the anchor block 9 is to provide a fixed anchor point for the first suction drive component float 1 by sinking to the target position on the bottom of the water. In aquatic environments, factors such as water flow and waves may cause the device to move, and the anchor block 9 can effectively resist these external forces, ensuring that the device can be stably maintained in the predetermined position during debris removal operations, thereby ensuring the smooth progress of the debris removal work. For example, when cleaning debris from the net bag 10 in areas with rapid water flow, without the anchor block 9 for fixation, the device may be swept away by the water flow, making it impossible to accurately suction debris from the net bag 10.

[0094] After anchor block 9 sinks to the bottom, its own weight and friction with the bottom help stabilize the center of gravity of the entire device. This is crucial for the balance and stability of the device on the water surface, especially during operation. The pumping process may generate action and reaction forces, and if the center of gravity is unstable, the device may tilt or even overturn. The anchor block 9 effectively prevents this from happening, improving the safety and reliability of the device.

[0095] The anchor block connector 91 is used to connect the anchor block 9 and the first suction drive component float 1, serving to transmit force. It needs to possess sufficient strength and durability to withstand various forces acting on the anchor block 9 at the bottom of the water, as well as the tension generated by the movement and swaying of the device on the water surface. For example, in situations with strong currents, the anchor block connector 91 must be able to securely connect the anchor block 9 and the first suction drive component float 1 to prevent them from separating and ensure the stability of the device.

[0096] In some cases, the anchor block connector 91 may also need to possess a certain degree of flexibility and adjustability. For example, when it is necessary to adjust the position or depth of the device, this can be achieved by adjusting the anchor block connector 91. This flexibility and adjustability allows the device to better adapt to different aquatic environments and cleaning needs. For instance, when operating in areas with different water depths, the length of the anchor block connector 91 can be adjusted to ensure that the anchor block 9 can accurately sink to the target position on the bottom of the water, while ensuring that the first suction drive component float 1 is in the appropriate position on the water surface.

[0097] The design of the anchor block 9 and anchor block connector 91 works in conjunction with other components of the net-bag sludge suction device, such as the guide pipe 3, the net-bag suction pipe 4, and the discharge pipe, to jointly ensure the stability of the device and the cleaning effect. The anchor block 9's fixation of the first suction drive component float 1 helps maintain the relative position stability of components such as the guide pipe 3 and the net-bag suction pipe 4, ensuring the normal operation of the entire device during suction and discharge. For example, if the first suction drive component float 1 moves due to factors such as water flow, the net-bag suction pipe 4 may not accurately connect with the net 10, affecting the cleaning efficiency; the anchor block 9's fixing function can prevent this from happening.

[0098] Through the action of anchor block 9 and anchor block connector 91, the device can stably perform cleaning operations at a predetermined position, thereby improving the accuracy and efficiency of cleaning. The stable device position allows the net suction pipe 4 to connect more effectively with the net 10 and ensures that the sewage discharge pipe can discharge sewage according to the predetermined path, avoiding problems such as inaccurate sewage discharge or incomplete cleaning caused by device movement.

[0099] Please refer to it again. Figure 3In one embodiment, a flange 20 is connected between the main guide pipe 3 and the first suction drive 2, and a flange 20 is connected between the first suction drive 2 and the first suction drive float 1.

[0100] A connector is provided between the drain pipe and the first suction drive component 2.

[0101] Specifically, flange 20 is a disc-shaped component widely used in pipeline engineering. In this net-type sludge suction device, flange 20 connects the main guide pipe 3, the first suction drive component 2, and the first suction drive component float 1, providing reliable connection strength. By bolting the two flange 20 discs together, the main guide pipe 3 and the first suction drive component 2 are securely mounted on the first suction drive component float 1, ensuring that during device operation, the components will not loosen or detach due to external forces (such as water flow impact or vibration generated by suction). Simultaneously, the flange 20 connection also provides excellent sealing performance. Sealing gaskets are typically installed between the flange 20 discs to effectively prevent fluid leakage (such as water containing sludge), ensuring the normal operation of the suction and conveying process and avoiding environmental pollution or impact on the device's working efficiency due to leakage.

[0102] The flange 20 connection structure facilitates the installation and disassembly of components. During assembly, each component can be installed separately and then connected via flange 20. When maintenance, repair, or component replacement is required, the flange 20 connection can be easily disassembled to separate components such as the guide pipe 3 and the first suction drive component 2, facilitating subsequent operations. This ease of installation and disassembly is significant for improving the maintainability and service life of the device, reducing maintenance costs and downtime.

[0103] Flange 20 connection is a standardized connection method with wide applicability. Standardized flange 20 discs and related accessories from different manufacturers can be used interchangeably. This facilitates the selection of suitable flange 20 discs and connectors during the design and manufacturing process of the device, and also makes it easier to replace and procure spare parts during subsequent use. Furthermore, the standardized flange 20 connection helps ensure connection quality and reliability, as its design and manufacturing adhere to certain standards and specifications.

[0104] A connector is used to connect the sewage pipe and the first suction drive component 2. The connector's function is to ensure a reliable connection between the sewage pipe and the first suction drive component 2. Compared to the flange 20 connection, the connector may have different structures and characteristics to meet the specific connection requirements between the sewage pipe and the first suction drive component 2. For example, the connector may prioritize connection flexibility, accommodating angle changes or displacements that may occur in the sewage pipe during installation and use, ensuring that the sewage pipe can smoothly transport waste from the first suction drive component 2 to the designated discharge area.

[0105] During operation, sewage pipes may be affected by varying pressures, temperatures, and fluid characteristics. The selection and design of fittings must consider these factors to ensure reliable connections and tight seals. For example, if the sewage within the pipe is corrosive, the fitting may be made of corrosion-resistant materials or have special anti-corrosion treatments to prevent damage and ensure proper operation of the system. Furthermore, the fitting's structural design may also facilitate the installation and disassembly of the sewage pipe, as well as maintenance and replacement under different operating conditions.

[0106] Both the flange 20 connection and the joint connection are designed to ensure that all components of the net bag sludge suction device can work together. The flange 20 connection ensures a stable connection between the guide pipe 3, the first suction drive component 2, and the first suction drive component float 1, while the joint connection ensures an effective connection between the discharge pipe and the first suction drive component 2. This allows the entire device to form a complete system, realizing a continuous process from the net bag 10 suctioning sludge to discharging sludge, thus improving the device's working efficiency and reliability.

[0107] Secondly, a nuclear power plant waste removal device is provided, comprising a main body of the nuclear power plant waste removal device and the aforementioned net-like waste suction device, wherein the main body of the nuclear power plant waste removal device is connected to the net-like waste suction device.

[0108] By adopting the above technical solution, in addition to the advantages of the net bag sewage suction device of the above embodiment, the nuclear power plant sewage suction equipment of this embodiment also has the advantage of high maintenance efficiency.

[0109] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
