Description

Technical Field

[0001] The utility model relates to the technical field of nuclear power, in particular to an underwater dust suction vehicle. Background Art

[0002] The management and disposal of spent fuel is a crucial component of nuclear power plant and reactor operations. Spent fuel, a byproduct of nuclear reactions, not only contains highly radioactive nuclides but also continues to release significant amounts of decay heat after the reaction ceases. This requires long-term storage under stringent conditions to ensure safety and await subsequent processing. During this process, spent fuel pools serve as temporary storage locations for spent fuel, and maintaining their internal environment is directly related to their safe storage and radiation protection.

[0003] However, in practice, spent fuel inevitably carries with it various impurities, such as particulate matter and metal debris, during its unloading from the reactor and transportation to the spent fuel pool. These impurities gradually settle at the bottom of the pool, forming silt, or float on the surface, forming a layer of floating ash. Over time, the accumulation of this silt and floating ash not only affects the clarity of the pool water but also negatively impacts its cooling and radiation shielding capabilities. More seriously, they can hinder the real-time monitoring of the spent fuel's condition, such as the accurate acquisition of key parameters like temperature and radiation levels, thereby compromising the effective assessment and management of the spent fuel storage condition.

[0004] Furthermore, the deionized water used in spent fuel pools must meet extremely high water quality requirements to meet the cooling and radiation protection requirements for the spent fuel. Excessive silt, floating ash, and other debris in the pools directly threatens the stability and purity of the water, potentially impairing the pool's cooling efficiency and radiation shielding effectiveness, posing a potential threat to the long-term safe storage of spent fuel.

[0005] Therefore, it is particularly important to develop an efficient and reliable cleaning device to clean the silt and floating ash in the spent fuel pool. Therefore, an underwater dust suction vehicle is proposed to solve the above technical problems. Utility Model Content

[0031] By adopting the above technical solution, the brush disc device 22 is installed at the front end of the trolley body 4, and can directly act on the path passed by the trolley. By rotating the brush disc, it can effectively loosen and remove sediments, dirt, etc. attached to the bottom or surface, which can significantly improve the efficiency of subsequent dust collection and ensure a more thorough cleaning effect. At the same time, the brush disc device can also adapt to underwater surfaces of different materials and shapes, increasing the flexibility and adaptability of cleaning. The underwater dust suction device 21 is installed above the trolley body 4 and is connected to the underwater vacuum cleaner. It is responsible for sucking in and collecting dirt, particulate matter, etc. loosened by the brush disc device. Since the dust suction device is located above the trolley, it can avoid being blocked by ground obstacles, ensuring the smooth progress of the dust suction process. The design of the dust suction device usually takes into account the special underwater environment, such as water flow resistance, pressure changes and other factors, thereby achieving efficient and stable dust suction effects.

[0032] The brush plate device 22 includes a brush plate 221, a brush plate sealed cabin 222 and a brush plate watertight joint 223. The brush plate watertight joint 223 is connected to the top of the brush plate sealed cabin 222. The brush plate 221 is installed at the bottom of the brush plate sealed cabin 222. The brush plate watertight joint 223 passes through the head of the trolley body 4 and is connected to external equipment.

[0033] By adopting the above technical solution, the design of the brush plate sealing cabin 222 effectively isolates the underwater environment from direct contact with the internal mechanism of the brush plate, prevents moisture, impurities, etc. from entering the brush plate, and protects key components such as the brush plate motor and transmission mechanism from damage. The brush plate watertight joint 223 serves as a bridge connecting the brush plate sealing cabin and external equipment, and also adopts a high-sealing performance design to ensure the sealing of the entire brush plate device during underwater operation and prevent water leakage.

[0034] The brush disc device 22 also includes a water shield 224, which is installed inside the trolley body 4 and connected to the rear end of the brush disc 221. The water shield 224 surrounds the rear area where the brush disc 221 passes, and the water shield 224 is connected to the underwater dust suction device 21.

[0035] By adopting the above technical solution, the water shield 224 is installed at the rear end of the brush disc 221, enclosing the rear area where the brush disc passes, effectively managing the water flow generated when the brush disc rotates, and preventing the water flow from directly impacting the vacuum cleaner inlet or causing secondary pollution to the surrounding environment.

The other end of the dust suction pipe 211 is connected to the upper end of the brush plate water shield 224.

[0037] By adopting the above technical solution, the dust suction pipe 211 is directly connected to the upper end of the brush plate water shield 224. This design ensures that dirt, particulate matter, etc. loosened by the brush plate 221 during the cleaning process can be quickly sucked into the dust suction pipe 211. The suction pipe joint 212 is installed at one end of the dust suction pipe 211 for tight connection with the underwater vacuum cleaner, which not only ensures a stable connection between the dust suction pipe and the vacuum cleaner, but also ensures smooth transmission of airflow during the vacuuming process.

[0038] The wheel drive assembly 3 includes a drive wheel 31 and a drive device 32 . The drive device 32 is installed on the side of the trolley body 4 . The drive device 32 is connected to and drives the drive wheel 31 arranged on the side of the trolley body 4 .

[0039] By adopting the above technical solution, the side-mounted drive device 32 and drive wheel 31 help balance the center of gravity of the car, especially when turning or driving on uneven roads, and can provide better stability and controllability, so that the car can maintain a stable driving state even in complex environments.

[0040] The driving device 32 includes a wheel sealed cabin 321 and a wheel watertight joint 322 . The wheel watertight joint 322 is arranged on the top of the wheel sealed cabin 321 . The power cable and the control cable are led out of the wheel sealed cabin 321 through the wheel watertight joint 322 .

[0041] By adopting the above technical solution, the wheel sealed cabin 321 serves as a protective layer for the cable, providing an effective waterproof seal to prevent water from entering the interior of the drive device, avoiding electrical faults such as short circuit and corrosion caused by water intrusion, thereby ensuring the stable operation of the drive device in an underwater environment. The power cable and the control cable are led out of the wheel sealed cabin 321 through the wheel watertight joint 322, ensuring the safety and stability of the cable during the leading-out process. The sealing performance of the wheel watertight joint 322 effectively prevents moisture and impurities from entering the interior of the cable, thereby extending the service life of the cable.

[0042] The driving device 32 also includes a reduction motor 323 and a driver 324. Both the driver 324 and the reduction motor 323 are installed inside the wheel sealing cabin 321. The driver 324 controls the movement of the reduction motor 323. The reduction motor 323 is connected to the driving wheel 31 through a bevel gear for movement.

[0043] By adopting the above technical solution, the driver 324 and the reduction motor 323 are both installed inside the wheel sealing cabin 321. This design optimizes the spatial layout and reduces the number and volume of external equipment. The wheel sealing cabin 321 provides effective protection for these key components, preventing the intrusion of impurities such as water and dust, thereby extending the service life of the equipment.

[0044] The underwater camera assembly 1 includes an underwater camera 11 and a camera bracket 12 . The underwater camera 11 is fixed on the camera bracket 12 , and the camera bracket 12 is installed on the trolley body 4 .

[0045] By adopting the above technical solution, the combined use of the underwater camera 11 and the camera bracket 12 in the underwater camera assembly 1 provides a stable, flexible and efficient shooting platform for underwater operations or observations, and helps to improve operating efficiency and protect camera equipment.

[0046] The trolley body 4 includes a protective outer cover 41 and a trolley bottom plate 42. The camera bracket 12 and the dust suction pipe 211 are both installed on the trolley bottom plate 42. Handheld handles 43 are provided on both sides of the upper surface of the trolley bottom plate 42. The protective outer cover 41 surrounds the brush plate sealed cabin 222 and the outside of the wheel drive assembly 3. A mudguard 44 is also provided on the protective outer cover 41, and the mudguard 44 surrounds the periphery of the drive wheel 31.

[0047] By adopting the above technical solution, the trolley bottom plate 42 serves as the basic supporting structure of the entire trolley, which not only carries key components such as the camera bracket 12 and the dust suction pipe 211, but also ensures the stability of the trolley during movement through its sturdy design. The protective outer cover 41 further enhances the protection performance of the trolley. It surrounds the outside of the brush plate sealing cabin 222 and the wheel drive assembly 3, effectively preventing the intrusion of impurities such as water and mud, and protecting the normal operation of the internal equipment. The mudguard 44 surrounds the outer periphery of the driving wheel 31, effectively preventing the water and mud splashed by the wheel during rotation from polluting and damaging other parts of the trolley, which not only protects the trolley itself, but also extends the service life of the equipment.

[0048] During the specific implementation of the present invention, it is ensured that the underwater vacuuming trolley has been assembled and all components are firmly connected, including the connection between the underwater vacuuming device 21 and the external underwater vacuum cleaner, and the connection between the cable of the wheel drive assembly 3 and the control system. The battery or power supply is checked to ensure that the trolley can continue to work. The trolley is placed near the underwater operation area of ​​the spent fuel pool, the power of the external underwater vacuum cleaner is turned on to ensure that it is in working condition, the wheel drive assembly 3 on the trolley is started, and the reduction motor 323 is controlled by the driver 324 to rotate, thereby driving the drive wheel 31 to rotate, so that the trolley starts to move.

[0049] As the trolley moves, the brush disc 221 in the brush disc device 22 starts to rotate to clean the underwater path passed by the trolley. The brush disc 221 works inside the brush disc sealed cabin 222 to prevent water from entering and damaging the internal mechanical components. The dirt and water flow generated during the cleaning process of the brush disc 221 are enclosed in the rear area by the water shield 224 to prevent the dirt from scattering. The water shield 224 is connected to the underwater dust suction device 21 to ensure that the dirt can smoothly enter the dust suction system. The underwater dust suction device 21 sucks the dirt and water flow in the water shield 224 through the dust suction pipe 211, and is connected to the external underwater vacuum cleaner through the suction pipe joint 212 to transport the dirt to the outside for treatment;

[0050] During the cleaning operation, the underwater camera assembly 1 starts working. The underwater camera 11 is fixed to the camera bracket 12. As the trolley moves, it captures the underwater environment in real time. The operator can observe the video images sent back by the camera to understand the cleaning progress and effect, and adjust the movement direction and speed of the trolley in time. Based on the real-time monitoring image feedback, the operator can adjust the trolley's cleaning path, brush plate speed and other parameters to optimize the cleaning effect. If it encounters a difficult-to-clean area or obstacle, the operator can control the trolley to bypass it or perform special treatment.

[0051] When the cleaning operation is completed, the power supply of the wheel drive assembly 3 and the external underwater vacuum cleaner is turned off to stop the trolley from moving and vacuuming.
