Description

Technical Field

[0001] This utility model relates to the field of nuclear power plant maintenance technology, and in particular to an inhaler for cleaning water pools in nuclear facilities. Background Technology

[0002] In the field of nuclear power plant maintenance technology, the cleaning of nuclear facility pools plays a crucial role in ensuring the safe and stable operation of nuclear power plants. As key facilities in nuclear power plants, the cleanliness of the internal environment of reactor pools and spent fuel pools directly affects the operational safety of the nuclear reactor and the stability of nuclear fuel storage.

[0003] When cleaning nuclear reactor pools and spent fuel pools, vacuum cleaners are typically used to suck up water and contaminants, which are then purified using specialized facilities. However, the shape of the vacuum cleaner head limits its reach to the corners and edges of the pools, requiring multiple adjustments to the head position for cleaning, resulting in low efficiency. For the pool walls and bottom, due to their large area, directly using the vacuum cleaner head also presents inefficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an inhaler for cleaning a pool in a nuclear facility. The inhaler is used to connect to the suction port of a sludge suction device. The inhaler includes a suction main pipe and a suction port component, which are connected. The suction port component is configured to fit tightly against the pool in the nuclear facility.

[0005] Preferably, the inhaler is connected to the suction port of the vacuum cleaner via an adapter.

[0006] Furthermore, the inhalation main pipe has a hollow structure.

[0007] Furthermore, the inhalation port component includes a positioning plate, a bent tube, and a first inhalation port. The positioning plate is square. A first through hole is provided in the center of the positioning plate. The first inhalation port is welded to the four corner areas of the positioning plate. The outer wall of one end of the bent tube is welded to the inner wall of the main inhalation pipe, and the other end passes through the first through hole and is welded to the first inhalation port. The inhalation area is expanded through the first inhalation port.

[0008] Preferably, one end of multiple bends is welded to the main suction pipe in a circumferentially distributed manner.

[0009] Furthermore, the positioning plate is provided with a second through hole at each of its four corners, and the second through hole is located on the outside of the first suction inlet location; a hollow positioning tube is provided on the positioning plate near the suction main tube, and the positioning tube is located at the second through hole.

[0010] Furthermore, the central axis of the first suction port is parallel to one diagonal of the positioning plate.

[0011] Furthermore, a connector is welded between the first suction inlets, and the connector is also welded to the positioning plate. Preferably, the connector is a hollow structure.

[0012] Furthermore, the lower part of the connector is provided with a support foot, which is a groove-shaped component with a groove structure.

[0013] Furthermore, the inhalation port component includes an inhalation chamber, which includes a diffusion section and a flow collection section, and the flow collection section is provided with a second inhalation port.

[0014] Furthermore, the flow collection section is rectangular, and a roller is provided on the flow collection section, with the roller protruding from the horizontal plane where the flow collection section is located.

[0015] Furthermore, the horizontal plane of the roller's rolling axis is parallel to the horizontal plane of the collection section. When the roller rolls against the pool wall, a gap exists between the suction chamber and the pool wall, ensuring smooth flow during water suction. The suction device slowly rolls forward against the pool wall while suctioning out wastewater, achieving cleaning of the pool bottom or walls through a reciprocating operation.

[0016] This utility model has the following beneficial effects:

[0017] (1) The suction device in this utility model has a first suction port welded to the four corners of the positioning plate. By directly connecting with the suction port of the sewage suction device, the corners of the pool can be cleaned directly without having to change positions multiple times, and the corners of the pool can be cleaned efficiently.

[0018] (2) The positioning tube in this utility model is set as a hollow structure to reduce the resistance when the inhaler is lowered. Since it is set at the four corners of the positioning plate, it can fit tightly against the side wall of the pool.

[0019] (3) The support legs in this utility model adopt a hollow structure, which leaves a large water flow channel below the suction port, making it easier to absorb water and pollutants and complete the cleaning of the area more quickly;

[0020] (4) The suction chamber in this utility model includes a diffusion section and a collection section, which is conducive to the collection and suction of sewage. The rectangular design of the collection section is matched with a roller that protrudes from the horizontal plane and the horizontal plane where the rolling shaft is located is parallel to the horizontal plane where the collection section is located, which makes it easy for the suction device to move in the pool, reduce the movement resistance, and improve the cleaning efficiency. When the roller rolls along the pool wall, there is a gap between the suction chamber and the pool wall. The suction device sucks up the sewage while slowly rolling forward along the pool wall. The bottom or wall of the pool is cleaned by the back-and-forth operation, and large areas can be cleaned quickly. Attached Figure Description

[0029] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. However, this embodiment is not intended to limit this utility model. Any similar structure or similar variation of this utility model should be included in the protection scope of this utility model. The commas in this utility model all indicate the relationship between and. The English letters in this utility model are case-sensitive.

[0030] Example 1

[0031] This embodiment provides an inhaler for cleaning water pools in nuclear facilities. This inhaler is a corner inhaler used to clean the corners of the water pool.

[0032] like Figure 1-4 As shown, the suction device 1 is connected to the suction port of the sludge suction device 2. The sludge suction device 2 can suction water through the suction device. The suction device 1 includes a suction main pipe 11 and a suction port component 12, which are connected. The suction port component 12 is configured to fit tightly against the water pool of the nuclear facility. The sludge suction device is a device used to remove solid contaminants and impurities from liquids or semi-fluids. It is existing equipment and not the focus of this protection scheme, so it will not be described further.

[0033] Preferably, the inhaler 1 is connected to the suction port of the vacuum cleaner via an adapter 4.

[0034] The inhalation tube 11 has a hollow structure.

[0035] like Figure 3-4 As shown, the suction port component 12 includes a positioning plate 121, a bent tube 122, and a first suction port 123. The positioning plate 121 is square. A first through hole 1211 is provided in the center of the positioning plate 121. The first suction port 123 is welded to the four corner areas of the positioning plate 121. The outer wall of one end of the bent tube 122 is welded to the inner wall of the suction main tube 11, and the other end passes through the first through hole 1211 and is welded to the first suction port 123. The suction area is expanded by the first suction port 123.

[0036] Preferably, one end of the plurality of bends 122 is welded in a circumferentially distributed manner inside the suction main pipe 11.

[0037] When cleaning corners, simply place the suction device 1 in the corner; it can efficiently clean the corners of the pool without needing to change position.

[0038] The positioning plate 121 has second through holes 1212 at its four corners, located on the outer side of the first suction port 123. A hollow positioning tube 13 is located on the side of the positioning plate 121 closest to the main suction tube 11, positioned at the second through holes 1212. The hollow structure of the positioning tube 13 facilitates the placement of the entire inhaler into the water tank. Because the positioning tube 13 is located at the four corners of the positioning plate, its outer wall can fit snugly against the tank wall at the corners, allowing for better corner cleaning. The central axis of the first suction port 123 is parallel to one diagonal of the positioning plate 121. A connector 14 is welded between the first suction ports 123 to increase their rigidity; the connector 14 is also welded to the positioning plate 121. The hollow structure of the connector 14 reduces the overall weight of the structure. Figure 5 As shown, the connecting body 14 is provided with a support leg 15 below. The support leg 15 is a groove-shaped component with a groove structure, which reduces the overall weight on the one hand, and leaves a large flow channel below the connecting body 14 on the other hand, which facilitates the absorption of water and pollutants and completes the cleaning of the area more quickly.

[0039] Since the positioning plate 121 is square, its two sides are close to the two sides of the pool, and the suction device's support legs 15 are in contact with the bottom of the pool. At this time, the suction device is in close contact with the three sides of the pool, and the first suction port 123 is directly facing the corner of the pool, so that the cleaning of the corner can be completed at this position.

[0040] like Figure 6As shown, this inhaler is particularly suitable for cleaning the bottom corners of the spent fuel grid 3 in the spent fuel water tank. The size of the positioning plate 121 is set to be slightly smaller than the square hole of the spent fuel grid 3. The inhaler is inserted into the bottom of the square hole of the spent fuel grid 3. The four first inhalation ports 123 of the inhaler are aligned with the four corners of the square hole, which can complete the cleaning of the bottom corners of the square hole faster and better.

[0041] Example 2

[0042] This embodiment provides an inhaler for cleaning water pools in nuclear facilities. This inhaler is a surface inhaler used for cleaning the walls and bottom of the water pool.

[0043] like Figure 7-8 As shown, the suction device 1 is connected to the suction port of the sludge suction device 2. The sludge suction device can suck up water through the suction device. The suction device 1 includes a suction main pipe 11 and a suction port component 12b, which are connected. The suction port component 12b is configured to fit tightly into the water pool of a nuclear facility. The sludge suction device is a device used to remove solid contaminants and impurities from liquids or semi-fluids. It is existing equipment and not the focus of this solution, so it will not be described further. The letter 'b' indicates a second structure of the suction port component in this invention.

[0044] Preferably, the inhaler is connected to the suction port of the vacuum cleaner via an adapter.

[0045] The inhalation tube 11 has a hollow structure.

[0046] The suction inlet component 12b includes a suction chamber, which comprises a diffuser section 21 and a collection section 22. The collection section 22 has a second suction inlet. The collection section 22 is rectangular and has a roller 23 protruding from the horizontal plane of the collection section 22. The horizontal plane of the roller 23's rolling axis is parallel to the horizontal plane of the collection section 22. When the roller 23 rolls against the pool wall, a gap exists between the suction chamber and the pool wall, ensuring smooth flow during water suction. The suction device slowly rolls forward against the pool wall while suctioning out waste, achieving cleaning of the pool bottom or wall through a back-and-forth operation.
