Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0031] In the description of the present application, “plurality” means at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0036] It should also be noted that, in the embodiments of the present application, the same figure mark is used to represent the same component or the same part. For the same parts in the embodiments of the present application, the figure may only mark one of the parts or components as an example. It should be understood that the figure mark also applies to other identical parts or components.

[0037] After a nuclear power plant pool has been in operation for a period of time, attachments are likely to form on the wall. The existing underwater purification system is unable to clean the attachments on the wall due to its own volume or weight limitations. Therefore, additional underwater cleaning equipment is needed to clean the wall of the pool.

[0038] At present, underwater cleaning devices are mostly used for cleaning the walls of water pools in nuclear power plants. The underwater cleaning devices include a suction and filtration device and a cleaning tool. The suction and filtration device and the cleaning tool are connected by a long suction hose to suck and filter dust and attachments formed during the operation. The long suction hose will cause a loss of suction pressure. In order to ensure the cleaning effect, the power of the suction and filtration device needs to be designed to be larger, resulting in a larger volume design of the suction and filtration device. The suction and filtration device is large in size and weight, and its movement at the bottom of the pool requires the help of a crane on the upper part of the pool, so that the entire cleaning operation requires the participation of multiple operators, which is difficult to operate.

[0039] Based on this, the underwater cleaning device of the embodiment of the present application integrates the suction and filtering device and the cleaning tool together, which can shorten the distance between the suction and filtering device and the cleaning tool, and reduce the loss of suction pressure caused by the excessively long suction hose, thereby reducing the suction power of the suction filtration, thereby reducing the volume and weight of the suction and filtering device, making the underwater cleaning operation time-saving and labor-saving, and also saving manpower, which is also conducive to improving the effect of underwater cleaning.

[0040] The underwater cleaning device of the embodiment of the present application can clean attachments on the walls of water pools in nuclear power plants (including core water pools, spent fuel water pools, refueling water pools, etc.).

[0041] The following combination Figures 1 to 8 The underwater cleaning device 100 according to the embodiment of the present application is described.

[0042] like Figures 1 to 4 As shown, in some embodiments, the underwater cleaning device 100 is used to clean the wall of the water pool of a nuclear power plant; the underwater cleaning device 100 includes a suction filtering device 10 and a cleaning tool 20, the cleaning tool 20 includes a mounting frame 21 and a cleaning tool 22 for cleaning the wall, the cleaning tool 22 is installed on the mounting frame 21, the mounting frame 21 is surrounded to form a suction cavity 2111, and the mounting frame 21 has a water inlet 2112 and a water outlet 2121 connected to the suction cavity 2111; wherein, the suction filtering device 10 is installed on the mounting frame 21, and the suction port 131 of the suction filtering device 10 is connected to the water outlet 2121.

[0043] The suction filtering device 10 may refer to a component for sucking water containing attachments on the wall of a water pool of a nuclear power plant into a suction chamber 2111 and filtering out the attachments.

[0044] The cleaning tool 20 may be a component used to clean the attached objects on the wall surface of the water pool of a nuclear power plant.

[0045] The cleaning tool 20 includes a mounting frame 21 and a cleaning tool 22. The mounting frame 21 may refer to the main part of the cleaning tool and serves as a mounting base for the cleaning tool 22 and the suction filtering device 10, thereby supporting the cleaning tool 22 and the suction filtering device 10. The mounting frame 21 may be made of a variety of materials, such as plastic, metal, etc.

[0046] The cleaning tool 22 may be a tool used to clean the wall of a water pool in a nuclear power plant. The cleaning tool 22 may be a rag, a brush 221 or other components.

[0047] In some examples, the brush 221 scrubs the wall surface to separate the attached objects on the wall surface from the wall surface.

[0048] The interior of the mounting frame 21 forms a cavity, which forms a suction cavity 2111. The mounting frame 21 has a water inlet 2112 and a water outlet 2121. The water inlet 2112 and the water outlet 2121 are both connected to the suction cavity 2111. The suction port 131 of the suction filter device 10 is connected to the water outlet 2121. The suction filter device 10 sucks the suction cavity 2111 through the suction port 131 and the water outlet 2121, so that the pressure in the suction cavity 2111 is reduced, so that the water containing the attachments can enter the suction cavity 2111 from the water inlet 2112, and then enter the suction filter device 10 through the water outlet 2121 and the suction port 131, so as to achieve the cleaning and filtering of the attachments.

[0049] In some examples, the cleaning tool 22 is disposed near the water inlet 2112, so that the attachments cleaned from the wall by the cleaning tool 22 can be sucked into the suction chamber 2111 through the water inlet 2112, and then enter the suction filtration device 10 for filtration and separation, thereby achieving the cleaning of the attachments.

[0050] The suction filter device 10 is installed on the mounting frame 21 , and the suction filter device 10 can be fixed on the mounting frame 21 by means of bolts, bonding, clamping, etc.

[0051] When the underwater cleaning device 100 of the embodiment of the present application is used, the underwater cleaning device 100 is placed in a pool, the water inlet 2112 of the cleaning tool 22 is set toward the wall to be cleaned, the cleaning tool 20 is pushed to move, and the cleaning tool 22 separates the attachments on the wall of the pool from the wall, and the suction and filtering device 10 is started. The suction and filtering device 10 sucks the suction chamber 2111 through the suction port 131 and the water outlet 2121, so that the pressure in the suction chamber 2111 is reduced, so that water containing attachments can enter the suction chamber 2111 through the water inlet 2112, and then enter the suction and filtering device 10 through the water outlet 2121 and the suction port 131 for filtration and separation, thereby achieving the cleaning of attachments on the wall of the pool. In the underwater cleaning device 100 of the embodiment of the present application, the suction filtering device 10 is installed on the mounting frame 21, so that the suction filtering device 10 and the cleaning operation tool 20 are integrated together, shortening the distance between the suction filtering device 10 and the cleaning operation tool 20, and reducing the loss of suction pressure caused by the excessively long suction hose, thereby reducing the suction power of the suction filtration, thereby reducing the volume and weight of the suction filtering device 10, making the underwater cleaning operation time-saving and labor-saving, and also saving manpower, which is also conducive to improving the effect of underwater cleaning.

[0052] In some cases, when the underwater cleaning device 100 is used to clean the wall of a nuclear power plant pool, a large area of ​​the pool wall is usually cleaned, so that the suction and filtration device 10 requires a larger suction power, thereby greatly increasing the volume and weight of the suction and filtration device 10.

[0053] When the underwater cleaning device 100 of the embodiment of the present application is in use, the suction and filtering device 10 is integrated with the cleaning tool 20, which is beneficial to reducing the volume of the entire underwater cleaning device 100, and is also beneficial to cleaning the wall of the nuclear power plant pool in a fixed point and small range. The small range cleaning can further reduce the suction power of the suction and filtering device 10, and further reduce the volume and weight of the suction and filtering device 10; therefore, the underwater cleaning device 100 makes the underwater cleaning operation time-saving and labor-saving, can also save manpower, and is also beneficial to improving the effect of underwater cleaning.

[0054] In some embodiments, the mounting frame 21 includes a main body 211, a tube body 212 and a support frame 213. The main body 211 is arranged to form a suction chamber 2111. A water inlet 2112 is formed on one side of the main body 211. The cleaning tool 22 is installed on the main body 211; the tube body 212 and the support frame 213 are installed on the other side of the main body 211. The suction filtering device 10 is installed on the support frame 213. One end of the tube body 212 is connected to the suction chamber 2111, and the other end of the tube body 212 is connected to the inlet of the suction filtering device 10.

[0055] The body 211 may refer to a main portion of the mounting frame 21 , and the body 211 may be made of materials such as metal and plastic.

[0056] The tube body 212 may refer to a tube with a hollow interior to form a channel. The tube body 212 is used to connect the suction chamber 2111 and the suction filter device 10, so that water in the suction chamber 2111 can enter the suction filter device 10 through the tube body 212 to filter and clean the attachments.

[0057] The support frame 213 may refer to a component used to support the suction filtering device 10 , and the support frame 213 is used for the installation of the suction filtering device 10 .

[0058] The main body 211 , the tube body 212 and the support frame 213 can be formed separately and then connected together by screw connection, clamping connection, welding and the like, or can be integrally formed by integral injection molding and the like.

[0059] In some examples, the body 211 is formed by bending a sheet metal of 1 mm to 2 mm, and is welded around stainless steel plates at the top, sides, and bottom, and an opening is provided on the bottom steel plate, which forms a water inlet 2112. The top steel plate is also provided with an opening, and one end of the tube body 212 is welded to the opening, and the other end of the tube body 212 can be directly connected to the suction port 131 of the suction filter device 10, or can be connected through a hose or other components.

[0060] By adopting the technical solution of this embodiment, the suction filtering device 10 is installed on the other side of the water inlet 2112 through the support frame 213, which can reduce the obstruction of the water inlet 2112 by the suction filtering device 10 and improve the cleaning effect of the pool wall. In addition, the setting of the tube body 212 can facilitate the connection between the suction cavity 2111 and the suction filtering device 10.

[0061] See also Figure 5 As shown, in some embodiments, the cleaning tool 22 includes two brushes 221 , which are mounted on the body 211 , and the two brushes 221 are located on opposite sides of the water inlet 2112 .

[0062] The brush 221 protrudes from the end surface of the body 211 provided with the water inlet 2112, so that the brush 221 can contact with the wall surface of the pool and scrub the wall surface of the pool.

[0063] The cleaning tool 22 includes two brushes 221, which have a good brushing effect on the wall of the pool, which is beneficial to improving the cleaning effect of the wall of the pool; the arrangement of the two brushes 221 can brush the wall of the pool twice when the cleaning tool 20 moves along the arrangement direction of the two brushes 221, which is beneficial to improving the cleaning effect of the wall of the pool; the two brushes 221 are located on opposite sides of the water inlet 2112, and the two brushes 221 are close to the water inlet 2112, which is convenient for the cleaned attachments to enter the suction chamber 2111, thereby realizing the cleaning of the wall of the pool.

[0064] In some embodiments, the underwater cleaning device 100 further includes a roller 214 , which is installed on the side of the body 211 facing away from the tube body 212 , and rollers 214 are provided on both opposite sides of the other side of the water inlet 2112 .

[0065] The roller 214 is rotatably mounted on the side of the body 211 facing away from the tube 212. During the movement of the cleaning tool 20, the roller 214 contacts the wall of the pool. The rolling of the roller 214 can reduce the moving resistance of the cleaning tool 20, and the moving and cleaning of the cleaning tool 20 is time-saving and labor-saving. The other two opposite sides of the water inlet 2112 are provided with rollers 214, so that the opposite sides of the cleaning tool 20 are supported by the rollers 214, and under the action of the rollers 214, the movement of the cleaning tool 20 is more convenient, and the roller 214 and the brush 221 are located on different sides of the water inlet 2112, which also reduces the interference of the brush 221 with the rolling of the roller 214, which is conducive to improving the smoothness of the rolling of the roller 214, and the moving and cleaning of the cleaning tool 20 is more convenient and labor-saving.

[0066] In some examples, there are four rollers 214, two of which are located on one side of the water inlet 2112 and at both ends of the water inlet 2112, and the other two rollers 214 are located on the other side of the water inlet 2112 and at both ends of the water inlet 2112, so that the four rollers 214 can support the four corners of the main body, making the movement of the cleaning tool 20 more stable and reliable. Of course, in other examples, the rollers 214 can also be arranged in other forms, which are not limited here.

[0067] See also Figure 6 As shown, in some embodiments, the suction filtering device 10 includes a motor 11, a pump suction filtering assembly 12 and a suction pipe 13. The pump suction filtering assembly 12 is installed on a mounting frame 21. The motor 11 is installed on the pump suction filtering assembly 12 and is used to drive the pump suction filtering assembly 12 to operate. The suction pipe 13 connects the water outlet 2121 and the inlet of the pump suction filtering assembly 12; the pump suction filtering assembly 12 has a drain outlet 121 for draining water.

[0068] The motor 11 drives the pump suction filter assembly 12 to operate, and the water containing attachments is sucked into the suction chamber 2111. The water in the suction chamber 2111 then enters the pump suction filter assembly 12 through the suction pipe 13 and is filtered by the pump suction filter assembly 12, and the water and attachments are separated. Finally, the filtered water is discharged into the pool through the drain port 121, thereby achieving suction filtration of attachments.

[0069] In some examples, the motor 11 drives the impeller in the pumping and filtering assembly 12 to rotate, thereby forming a vacuum suction force inside the pumping and filtering assembly 12, so that a vacuum negative pressure is also formed inside the suction pipe 13 and the suction chamber 2111, thereby sucking water containing attachments into the suction filtering device 10 for suction filtration.

[0070] The motor 11 can be installed on the pump suction filter assembly 12 by means of threads, clamping, bonding, etc., and the suction pipe 13 can be a hose, so that there is a certain installation error between the pump suction filter assembly 12 and the mounting frame 21, which is beneficial to reduce the assembly difficulty between the pump suction filter assembly 12 and the mounting frame 21, and facilitate the assembly of the suction filter device 10 and the mounting frame 21. Of course, in other examples, the suction pipe 13 can also be a hard pipe.

[0071] In some examples, the pump suction filter assembly 12 includes a submersible pump and a filter screen arranged in the submersible pump. The filter screen can be arranged at the water inlet 2112 of the submersible pump or at the water outlet 2121 of the submersible pump. The motor 11 drives the submersible pump to operate, sucking water into the suction filter device 10, and at the same time the filter screen filters the attachments in the water; the filter screen is detachably connected to the submersible pump, so that different filter screens can be selected according to different types of attachments to meet the cleaning requirements of different attachments.

[0072] By adopting the technical solution of this embodiment, the motor 11 and the suction pipe 13 are both installed on the pump suction filter assembly 12, so that the suction filter device 10 forms an integral module. The pump suction filter assembly 12 is installed on the mounting frame 21, so that the entire suction filter device 10 can be connected to the mounting frame 21, and it is also convenient to realize modular assembly of the underwater cleaning device. In addition, the suction filter device 10 forms an integral module, which is also conducive to reducing the volume and weight of the underwater cleaning module, and facilitating the use of the underwater cleaning device.

[0073] See also Figure 1 , Figure 7 and Figure 8 As shown, in some embodiments, the underwater cleaning device 100 further includes an operating rod 30 , one end of which is hinged to the mounting frame 21 .

[0074] The operating rod 30 may refer to a component for a person or equipment to hold to facilitate the movement of the underwater cleaning device. The operating rod 30 is hinged to the mounting frame 21 so that the angle between the operating rod 30 and the mounting frame 21 can be changed, thereby facilitating the underwater cleaning device to be suitable for cleaning walls at different angles, thereby improving the flexibility of cleaning the pool wall.

[0075] It should be noted that the angle between the operating rod 30 and the mounting frame 21 may refer to the angle α formed by the bottom surface of the mounting frame 21 with the water inlet 2112 and the axial direction of the operating rod 30. For example, the angle α may be 0°, 45°, 90°, etc.

[0076] In some examples, an external mechanical device is connected to the operating rod 30, and the operator can remotely operate the external mechanical device to drive the operating rod 30 to move. The operating rod 30 pushes the underwater cleaning device 100 to move on the bottom or side wall of the pool, thereby cleaning and filtering the attachments. In addition, remote operation can also reduce the risk of nuclear radiation exposure to the operator.

[0077] For example, when cleaning the bottom wall of the pool, the operating rod 30 can be set vertically relative to the cleaning tool 20. When cleaning the side wall of the pool, the operating rod 30 can be set parallel to the cleaning tool 20 to facilitate personnel or equipment to drive the cleaning tool to move.

[0078] In some embodiments, the underwater cleaning device further includes a locking member 40 , which is used to lock the operating rod 30 and the mounting bracket 21 , so that the operating rod 30 is tilted at different angles relative to the mounting bracket 21 .

[0079] The operating rod 30 is hinged to the mounting frame 21 so that the angle between the operating rod 30 and the mounting frame 21 is adjustable. When the angle between the operating rod 30 and the mounting frame 21 is adjusted to a preset angle, the locking member 40 can relatively fix the operating rod 30 and the mounting frame 21, thereby facilitating the cleaning of different pool walls.

[0080] In some embodiments, the operating rod 30 includes a rod portion 31, a first connecting plate 32 and two second connecting plates 33, one end of the two second connecting plates 33 are respectively connected to the two ends of the first connecting plate 32, the two second connecting plates 33 are located on one side of the first connecting plate 32, the rod portion 31 is connected to the middle part of the first connecting portion 215 and is located on the other side of the first connecting portion 215 plate; the mounting frame 21 is provided with two connecting portions 215, and the two connecting portions 215 are respectively hinged to the other ends of the two second connecting plates 33.

[0081] The first connecting plate 32 and the two second connecting plates 33 form a U-shaped structure or a structure similar to a U-shaped structure. The two ends of the U-shaped structure close to the opening are respectively hinged to the two connecting parts 215 on the mounting frame 21, which can improve the connection stability between the operating rod 30 and the mounting frame 21, making the use of the underwater cleaning device more stable and reliable. The bottom of the U-shaped structure is connected to the rod 31, which can be convenient for people and equipment to hold.

[0085] The hinge shaft 331 is perpendicular to the rod portion 31, and is passed through the first hinge hole 2151 of the connecting portion 215, and can rotate in the first hinge hole 2151, thereby realizing the hinge connection between the operating rod 30 and the mounting frame 21, so that the angle between the operating rod 30 and the mounting frame 21 can be changed.

[0086] In some examples, the second connecting plate 33 is provided with a second hinge hole, and the hinge shaft 331 is inserted into the first hinge hole 2151 and the second hinge hole, so as to realize the hinge connection between the operating rod 30 and the connecting portion 215. Both ends of the hinge shaft 331 are respectively inserted into the first hinge holes 2151 of the two connecting portions 215, and the second connecting portion 215 is located between the two connecting portions 215, so that the connection reliability between the operating rod 30 and the mounting frame 21 can be improved.

[0087] In some examples, the hinge shaft 331 may also be integrally formed with the second connecting plate 33 . For example, the hinge shaft 331 is a protruding structure on the surface of the second connecting plate 33 .

[0088] A plurality of first locking holes 2152 are arranged at intervals along the circumference of the first hinge hole 2151, and a plurality of first locking holes 2152 are distributed at intervals around the axis of the hinge shaft 331. During the rotation of the second connecting plate 33 around the hinge shaft 331, the locking member 40 is inserted into different first locking holes 2152, thereby fixing the operating rod 30 at different angles relative to the mounting frame 21, so as to be suitable for cleaning different pool walls.

[0089] In some examples, the second connecting plate 33 is provided with a second locking hole, and the locking member 40 passes through the second locking hole and the corresponding first locking hole 2152 , thereby achieving relative fixation of the second connecting plate 33 and the connecting portion 215 .

[0090] In some examples, the locking member 40 includes a locking portion and an elastic member, the second connecting portion 215 is provided with a mounting hole, the elastic member is installed in the mounting hole, one end of the locking portion is installed in the mounting hole and abuts against the elastic member, and the other end of the locking portion passes through the mounting hole and is inserted into the first locking hole 2152, thereby realizing the relative fixation of the second connecting plate 33 and the connecting portion 215; the locking portion is pressed to move toward the mounting hole to exit the first locking hole 2152, and at the same time, the locking portion compresses the elastic member, and after the locking portion completely exits the first locking hole 2152, the second connecting plate 33 can be pushed to rotate around the axis of the hinge shaft 331, and after the second connecting plate 33 rotates to a preset position, the locking portion is arranged relative to the corresponding first locking hole 2152, and at this time, under the automatic recovery force of the elastic member, the locking portion can be pushed to insert into the corresponding first locking hole 2152, so that the angle adjustment between the operating rod 30 and the mounting bracket 21 is realized. The elastic member can be a spring or other components. The locking portion and the spring can form a spring latch structure.

[0091] Through the hinged structure of the second connecting plate 33 and the connecting part 215, the operating rod 30 can be installed at the positions of 0°, 45°, and 90° relative to the mounting frame 21, so that the side walls and bottom walls of the pool can be cleaned, which improves the flexibility of the pool wall cleaning operation and reduces the operating difficulty of the operator.

[0092] In some embodiments, a traction portion 34 for connecting with a traction rope is provided at the end of the operating rod 30 facing away from the mounting frame 21 .

[0093] The traction part 34 can be a rod-shaped structure, and the traction part 34 is perpendicular to the rod part 31 to facilitate stable connection with the traction rope; the traction part 34 can also be an annular structure to facilitate the insertion and fixation of the traction rope and improve the connection reliability between the traction rope and the traction part 34.

[0094] By adopting the technical solution of this embodiment, a traction rope can be tied to the position of the traction portion 34, and the thrust required for the operating rod 30 can be reduced by utilizing the pulling force of the traction rope, thereby protecting the operating rod 30.

[0095] The underwater cleaning device 100 of the embodiment of the present application directly connects and fixes the suction and filtering device 10 to the cleaning operation tool, and the cleaning operation tool is directly connected to the suction port 131 of the suction and filtering device 10. By changing the position of the operating rod 30, the cleaning operation of the side wall and the bottom wall of the pool can be achieved, thereby improving the flexibility of the pool wall cleaning operation.

[0096] The underwater cleaning device 100 of the embodiment of the present application directly connects the small suction and filtering device 10 to the cleaning tool. It has a compact structural design and can perform pool wall cleaning operations through the operating rod 30, which greatly shortens the length of the suction hose and reduces the risk of reduced suction efficiency in the operation method of connecting the suction and filtering device 10 to the cleaning tool via a long-distance suction hose.

[0097] In some embodiments, the underwater cleaning device 100 can be used in conjunction with an underwater camera. The underwater camera is used to observe the condition of the attachments on the wall of the pool and determine the position of the wall to be cleaned; then, the operating rod 30 is rotatably hinged with the mounting frame 21. If the side wall attachments need to be cleaned, the operating rod 30 and the mounting frame 21 are in a 0° state. If the bottom pool wall attachments need to be cleaned, the operating rod 30 and the mounting frame 21 are in a 45° or 90° state; thereafter, the motor 11 is started, and the cleaning tool 20 is monitored with the help of the underwater camera. The operator remotely pushes the cleaning tool 20 to move along the wall, and the brush 221 scrubs the wall attachments. The scrubbed sewage enters the suction chamber 2111 through the water inlet 2112, and then flows into the suction pipe 13 from the water outlet 2121, and then flows into the pump suction filter assembly 12 for filtration. Finally, the filtered water is discharged into the pool through the drain port 121, and the water circulates inside the pool.
