[0003] The fuel loading and unloading system is one of the key systems that affect the economy and safety of the reactor in the high temperature gas cooled reactor nuclear power plant. In each process of the fuel loading and unloading system, including fuel burnup measurement, lifting and loading, the operation is completed based on single spherical elements, so the single output device for spherical elements is a key component of the system.

[0004] The single output device in the prior art adopts a rotating structure, the rotor is rotated to a coaxial position of the ball inlet channel, the spherical element enters the rotor ball cup from the ball inlet channel by gravity, the rotor is rotated by 180 degrees, and the spherical element enters the ball outlet channel from the rotor ball cup by gravity. In a high-frequency operating environment, the structure has strict requirements on the control accuracy of the rotating angle of the driving motor, and misalignment may easily cause the spherical element to be cut or stuck; in addition, if there are adhesion debris in the ball cup, the height of the spherical element after falling into the ball cup exceeds the gap between the ball cup and the working cavity, and the rotor may cause the box to cut the spherical element when rotating.

DETAILED DESCRIPTION

[0055] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0056] As Figures 1-4 shown, the embodiment of the present application discloses a spherical element single-output device including a box 1, a baffle 15, a positioning plate 20, a baffle driving device, and a positioning plate driving device.

[0057] The box 1 has a spherical element channel and a baffle working cavity 101 and a positioning plate working cavity 102 communicating with the spherical element channel. The two ends of the spherical element channel are respectively a spherical element inlet 104 and a spherical element outlet 105. The spherical element 10 (for example, it can be a spherical fuel element in the field of nuclear reactors, or any spherical structure element that exists in the single-output field) enters the spherical element channel through the spherical element inlet 104 and rolls in the direction of the spherical element outlet 105. In order to ensure that the spherical element 10 can roll under the action of gravity, the position of the spherical element single-output device can be adjusted so that the spherical element channel is arranged as shown in Figure 1 , that is, it has a certain angle with the horizontal direction, or the spherical element channel is perpendicular to the horizontal direction, that is, the spherical element channel is arranged along the vertical direction.

[0058] The baffle working cavity 101 is arranged closer to the spherical element outlet 105 than the positioning plate working cavity 102. If the direction from the spherical element inlet 104 to the spherical element outlet 105 is the conveying direction of the spherical elements 10, then the baffle working cavity 101 is located downstream of the conveying direction of the spherical elements 10, and the positioning plate working cavity 102 is located upstream of the conveying direction of the spherical elements 10.

[0059] The baffle 15 is slidably arranged in the baffle working cavity 101, and can slide into the spherical element channel to prevent the spherical elements 10 from sliding along the spherical element channel. The baffle 15 can be driven to slide by the baffle driving device.

[0060] In order to limit the sliding direction of the baffle 15 and improve the stability of the sliding of the baffle 15, a baffle guide groove 106 is arranged on the side wall of the baffle working cavity 101 and slidably cooperates with the baffle 15. Under the action of an external force, the baffle 15 can be driven to slide along the baffle guide groove 106. When sliding to the limit position in the direction towards the spherical element channel, the baffle 15 can block the spherical elements 10 upstream to prevent the spherical elements 10 from sliding along the spherical element channel. When sliding to the limit position in the direction away from the spherical element channel, the baffle 15 can remove the blocking effect on the spherical elements 10, and then the spherical elements 10 can slide along the spherical element channel.

[0061] The positioning plate 20 is slidably arranged in the positioning plate working cavity 102, and when the baffle 15 removes the blocking effect on the spherical element 10 closest to the positioning plate 20, the positioning plate 20 is used to prevent the remaining spherical elements 10 (i.e. all spherical elements 10 except the spherical element 10 closest to the positioning plate 20 which is removed by the baffle 15) from sliding along the spherical element channel. The positioning plate 20 can be driven to slide by the positioning plate driving device.

[0062] In order to limit the sliding direction of the positioning plate 20 and improve the stability of the sliding of the positioning plate 20, a positioning plate guide groove 107 is arranged on the side wall of the positioning plate working cavity 102 and slidably cooperates with the positioning plate 20. Under the action of an external force, the positioning plate 20 can be driven to slide along the positioning plate guide groove 107. When sliding to the limit position in the direction towards the spherical element channel, the positioning plate 20 can block the spherical elements 10 upstream to prevent the spherical elements 10 upstream of the positioning plate 20 from sliding along the spherical element channel. When sliding to the limit position in the direction away from the spherical element channel, the positioning plate 20 can remove the blocking effect on the spherical elements 10, and then the spherical elements 10 can slide along the spherical element channel.

[0063] In order to limit the sliding direction of the positioning plate 20 and improve the stability of the sliding of the positioning plate 20, a positioning plate guide groove 107 is arranged on the side wall of the positioning plate working cavity 102 and slidably cooperates with the positioning plate 20. Under the action of an external force, the positioning plate 20 can be driven to slide along the positioning plate guide groove 107. When sliding to the limit position in the direction towards the spherical element channel, the positioning plate 20 can block the spherical elements 10 upstream to prevent the spherical elements 10 upstream of the positioning plate 20 from sliding along the spherical element channel. When sliding to the limit position in the direction away from the spherical element channel, the positioning plate 20 can remove the blocking effect on the spherical elements 10, and then the spherical elements 10 can slide along the spherical element channel. Figure 1The shown scheme is an example, the spherical elements 10 arranged in the direction from the spherical element outlet 105 to the spherical element inlet 104 are respectively a first spherical element, a second spherical element, and an nth spherical element. The first spherical element is blocked by the baffle 15 and cannot continue to move towards the spherical element outlet 105, and the second spherical element is positioned by the positioning plate 20 to limit the movement of the second spherical element towards the spherical element outlet 105. When the spherical element 10 needs to be output, the baffle 15 is first lifted so that the baffle 15 removes the blocking effect on the first spherical element, and the first spherical element is discharged from the spherical element outlet 105 under the action of gravity.

[0064] Then, the baffle 15 is returned to the spherical element channel to meet the second spherical element. Then, the positioning plate 20 is lifted so that the positioning plate 20 removes the blocking effect on the second spherical element, and the second spherical element and the upstream spherical elements each roll downstream under the action of gravity until the second spherical element abuts against the baffle 15 and is blocked by the baffle 15. Then, the positioning plate 20 falls and clamps the third spherical element. The previous steps are repeated so that the spherical elements 10 are sequentially discharged one by one.

[0065] Those skilled in the art can understand that, according to the positional relationship between the baffle 15 and the positioning plate 20, the spherical elements 10 can be sequentially discharged n by n, for example, two spherical elements 10 can be discharged at a time, and only the positioning plate 20 needs to block the third spherical element when the baffle 15 blocks the first spherical element.

[0066] The spherical element singulation output device provided by the application is provided with a spherical element channel on the box 1, and in specific use, the spherical element channel can be arranged obliquely so that the spherical elements 10 entering from the spherical element inlet 104 can automatically roll in the direction of the spherical element outlet 105 under the action of gravity. The baffle 15 can slide along the baffle working cavity 101 under the action of the baffle driving device so as to be able to slide into and out of the spherical element channel, thereby enabling the baffle 15 to block the spherical elements 10 in the spherical element channel from rolling in the direction of the spherical element outlet 105 when the baffle 15 slides into the spherical element channel. The positioning plate 20 can slide along the positioning plate working cavity 102 under the action of the positioning plate driving device so as to be able to slide into and out of the spherical element channel, thereby enabling the positioning plate 20 to prevent the remaining spherical elements from sliding along the spherical element channel when the positioning plate 20 slides into the spherical element channel. The application can enable the spherical elements downstream of the positioning plate 20 to be discharged at a time, and the positioning plate 20 can improve the reliability of the singulation output of the spherical fuel elements.

[0067] As Figure 2As shown, the baffle 15 slides between the first baffle position and the second baffle position. The first baffle position and the second baffle position of the baffle 15 only need to ensure that they can block and release the spherical element 10, so that when the baffle 15 is driven by the baffle driving device to slide between the first baffle position and the second baffle position, it can switch between blocking and releasing the spherical element 10.

[0068] When in the first baffle position, the baffle 15 slides into the spherical element channel to prevent the first spherical element 10 from passing through. When in the second baffle position, the baffle 15 exits the spherical element channel to allow the first spherical element 10 to pass through. The first spherical element 10 is the spherical element 10 closest to the spherical element outlet 105 when the baffle 15 is in the first baffle position.

[0069] like Figure 3 As shown, the positioning plate 20 slides between the first positioning plate position and the second positioning plate position. The first positioning plate position and the second positioning plate position of the positioning plate 20 only need to ensure that they can block and release the spherical element 10, so that when the positioning plate 20 slides between the first positioning plate position and the second positioning plate position driven by the positioning plate driving device, it can switch between blocking and releasing the spherical element 10.

[0070] When the positioning plate is in the first positioning plate position, the positioning plate 20 slides into the spherical element channel to prevent the second spherical element 10 from passing through. When the positioning plate is in the second positioning plate position, the positioning plate 20 exits the spherical element channel to allow the second spherical element 10 to pass through. The second spherical element 10 is the spherical element 10 closest to the first spherical element 10 when the baffle 15 is in the first baffle position.

[0071] In one specific embodiment of the present invention, the surface of the positioning plate 20 facing the spherical element 10 is an arc-shaped surface that fits against the spherical element 10. When the positioning plate 20 is in the position of the first positioning plate, the positioning plate 20 slides into the channel of the spherical element, and the arc-shaped surface of the positioning plate 20 fits against the spherical surface of the second spherical element 10 to restrict the second spherical element 10 from sliding downstream. It should be noted that the positioning plate 20 can also be a plate-like structure, which can be inserted between the first spherical element and the second spherical element.

[0072] Further, a side surface of the baffle 15 facing the spherical element inlet 104 is a first surface, and a center of symmetry of the arc surface of the positioning plate 20 is a first center of symmetry, both of which are perpendicular to the axis of the spherical element channel. The distance between the first surface of the baffle 15 and the center of symmetry of the arc surface of the positioning plate 20 is 1.5D, where D is the diameter of the spherical element 10, so that when the baffle 15 blocks the first spherical element, the arc surface of the positioning plate 20 presses the upper surface of the second spherical element, and the center of symmetry of the arc surface of the positioning plate 20 passes through the center of the second spherical element, to ensure better pressing effect.

[0073] On the basis of the above embodiment, the diameter of the arc surface of the positioning plate 20 can be the same as the diameter of the spherical element 10, both of which are D. The height of the circular arc of the arc surface of the positioning plate 20 is S20, and 0.2D≤S20≤0.25D. As long as the height S20 of the circular arc of the arc surface of the positioning plate 20 is between 0.2D and 0.25D, the spherical element 10 can be effectively fixed. If S20 is less than 0.2D, although the spherical element 10 can also be fixed by pressing force, the contact area is too small, and the spherical element 10 may shake. If S20 is greater than 0.25D, the contact area is too large, and the positioning plate 20 may be stuck when falling.

[0074] As shown in FIG. 1, Figure 1 In the embodiment, the baffle driving device can include a baffle driving rod for driving the baffle 15 to act, and the positioning plate driving device can include a positioning plate driving rod for driving the positioning plate 20 to act.

[0075] The axis of the baffle driving rod passes through the center of symmetry of the thickness of the baffle 15, and the axis of the positioning plate driving rod passes through the first center of symmetry. Half of the thickness of the baffle 15 is b, and S0 is the distance between the axis of the baffle driving rod and the axis of the positioning plate driving rod, so that S0=b+1.5D.

[0076] In a specific embodiment of the present application, the spherical element singleization output device can further include an upper end cover 2, one end of the baffle working cavity 101 and the positioning plate working cavity 102 is communicated with the spherical element channel, and the other end penetrates the mounting end surface of the box body 1, and the upper end cover 2 is arranged on the mounting end surface of the box body 1 and covers the baffle working cavity 101 and the positioning plate working cavity 102. The baffle driving device and the positioning plate driving device are both linear motors arranged on the upper end cover 2. It should be noted that the baffle driving device and the positioning plate driving device can also be other linear driving devices. The driving devices capable of realizing linear driving action are widely used in the prior art, such as piston rod devices, screw mechanism devices, rack devices, etc.

[0077] As shown in FIG. 1, Figure 2As shown, the upper end cover 2 is provided with a baffle stator cavity 108, and the baffle driving device includes a baffle stator 12 and a baffle mover 3 (which can be understood as the baffle driving rod in the above embodiment).

[0078] The baffle stator 12 is arranged in the baffle stator cavity 108, the baffle mover 3 is arranged in the center of the baffle stator 12, and the first end is connected with the baffle 15. The upper end cover 2 is provided with a baffle mover stroke cavity 201 for providing stroke space for the second end of the baffle mover 3. The baffle mover 3 is supported in the baffle mover stroke cavity 201 by the upper linear bearing 11, and is supported on the lower bearing support 14 by the lower linear bearing 13. The lower bearing support 14 is fixed to one end of the baffle stator cavity 108 close to the box body 1.

[0079] As shown in the figure, Figure 3 The upper end cover 2 is provided with a positioning plate stator cavity 109, and the positioning plate driving device includes a positioning plate stator 17 and a positioning plate mover 9 (which can be understood as the positioning plate driving rod in the above embodiment).

[0080] The positioning plate stator 17 is arranged in the positioning plate stator cavity 109, the positioning plate mover 9 is arranged in the center of the positioning plate stator 17, and the first end is connected with the positioning plate 20. The upper end cover 2 is provided with a positioning plate mover stroke cavity 202 for providing stroke space for the second end of the positioning plate mover 9. The positioning plate mover 9 is supported in the positioning plate mover stroke cavity 202 by the upper linear bearing 16, and is supported on the lower bearing support 19 by the lower linear bearing 18. The lower bearing support 19 is fixed to one end of the positioning plate stator cavity 109 close to the box body 1.

[0081] As shown in the figure, Figure 2 As shown in the figure, the baffle mover stroke cavity 201 provides a stroke length S11 for the second end of the baffle mover 3, that is, when the baffle 15 is located at the first baffle position, the distance between the second end of the baffle mover 3 and the end face of the end of the baffle mover stroke cavity 201 away from the baffle 15 is S11.

[0082] The baffle working cavity 101 provides a stroke length S12 for the baffle 15, and the diameter of the spherical element 10 is D, then S11≥1.2D and / or S12≥1.2D, S11 and S12 are close, preferably equal. In this embodiment, S11 and S12 are designed to be not less than 1.2 times the diameter of the spherical element 10, which provides sufficient stroke space for the baffle 15 and the baffle mover 3, avoids interference phenomenon, and ensures the reliable opening and closing of the baffle 15.

[0083] In a specific embodiment of the present invention, a baffle limiting step a1 is provided at one end of the baffle working cavity 101 near the spherical element channel, and a baffle limiting flange is provided on the baffle 15 to limit and cooperate with the baffle limiting step a1. When the baffle limiting flange moves to abut against the baffle limiting step a1, there is a first preset gap between the end face of the baffle 15 facing the spherical element channel and the spherical element channel. For example, the first preset gap can be designed to be 2mm. Those skilled in the art will understand that the first preset gap can also be designed to be other distances, such as 1mm, 3mm, etc., and the specific first preset gap should be set according to actual needs.

[0084] In this embodiment, by designing a first preset gap, when the baffle 15 falls to the limit position (the baffle limiting edge moves to abut against the baffle limiting step a1), there is still a certain distance between the baffle 15 and the spherical element channel, so as to avoid the baffle 15 impacting the surface of the spherical element channel when it falls.

[0085] like Figure 3 As shown, the stroke length provided by the positioning plate mover stroke cavity 202 to the second end of the positioning plate mover 9 is S21, that is, when the positioning plate 20 is in the first positioning plate position, the distance between the second end of the positioning plate mover 9 and the end face of the positioning plate mover stroke cavity 202 that is away from the positioning plate 20 is S21.

[0086] The working cavity 102 of the positioning plate provides a stroke length of S22 for the positioning plate 20. The diameter of the spherical element 10 is D. Therefore, S21 ≥ 1.5S20 and / or S22 ≥ 1.5S20. S21 and S22 are close, preferably equal. In this embodiment, S21 and S22 are designed to be no less than 1.5 times S20 (in principle, as long as they are greater than S20), providing sufficient stroke space for the positioning plate 20 and the positioning plate mover 9, avoiding interference, and ensuring the reliable opening and closing of the positioning plate 20.

[0087] In a specific embodiment of the present invention, a positioning plate limiting step a2 is provided at one end of the positioning plate working cavity 102 near the spherical element channel. A positioning plate limiting stop is provided on the positioning plate 20 to limit and cooperate with the positioning plate limiting step a2. When the positioning plate limiting stop moves to abut against the positioning plate limiting step a2, a second preset gap exists between the end face of the positioning plate 20 facing the spherical element channel and the spherical element. For example, this second preset gap can be designed to be 2mm. Those skilled in the art will understand that the second preset gap can also be designed to other distances, such as 1mm, 3mm, etc., and the specific setting of the second preset gap should be based on actual needs.

[0088] The second preset gap is designed, so that when the positioning plate 20 falls to the limit position (the positioning plate limiting stop edge moves to abut against the positioning plate limiting step a2), the positioning plate 20 and the spherical element 10 still have a certain distance, avoiding the impact of the positioning plate 20 on the surface of the spherical element 10 when falling.

[0089] In an embodiment of the present application, the spherical element single output device can further comprise a position sensor 7 arranged on the upper end cover 2 and corresponding to the baffle mover stroke cavity 201 and the positioning plate mover stroke cavity 202, respectively, for detecting the positions of the baffle mover 3 and the positioning plate mover 9, respectively. Specifically, the upper end cover 2 can be provided with a sensor embedding groove, and the position sensor 7 can be press-fitted in the sensor embedding groove through a position sensor end cover 8, and the sensor end cover 8 can be fixed on the upper end cover 2 through fasteners. The position sensor 7 can obtain the positions of the baffle mover 3 and the positioning plate mover 9, so as to determine the positions of the baffle 15 and the positioning plate 20, that is, whether the baffle 15 and the positioning plate 20 are in an open (i.e., unblocked) state or a blocked state.

[0090] Further, the upper end cover 2 is fixed with an electrical penetration member 6 for passing through a power supply circuit at an end away from the box body 1, and the electrical penetration member 6 and the upper end cover 2 are sealed by a metal sealing ring 5. The upper end cover 2 is provided with a wiring cavity 103, and the stator coil connecting lines 4 of the baffle stator 12 and the positioning plate stator 17 are connected with the power supply circuit in the wiring cavity 103. In the present embodiment, the corresponding lines are sealed in the wiring cavity 103, and such a sealing structure can ensure that the present application can work in a high-temperature high-pressure helium environment.
