Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of nuclear power, and more specifically relates to an adapter salvaging tool. Background Art
[0002] A large number of related components are needed during the operation of nuclear power plants, especially units using burnable poisons, which will use a large number of nuclear fuel-related component adapters in the early stage. Each adapter will occupy nine fuel assembly storage racks. The use of a large number of adapters will occupy too many racks, resulting in a reduction in the fuel storage capacity of the spent fuel pool. Therefore, the adapters need to be removed from the water before the storage racks are full.
[0003] There are generally two ways to remove the adapter from the water: one is to grab the adapter with a spent fuel long-handled tool, and then lift it to the new fuel elevator through a spent fuel crane, and then lift the adapter out of the water through the new fuel elevator. The tool lifting and elevator lifting both take a lot of time and effort, and there is also the risk of the adapter falling off the spent fuel long-handled tool, and the risk of the adapter getting stuck when the elevator lifts it; the second is to use a hook to remove the water. Although this method is fast, it has a higher risk of falling off than the first solution. Regardless of which method is used to remove the water, once the adapter falls off, it will hit the fuel assembly or the fuel storage grid. In the least, the fuel storage grid will be unusable, and in the worst case, it will cause a nuclear safety IOE event in which the fuel assembly is damaged. The unusable fuel assembly may affect the subsequent overhaul and lose the use efficiency of the fuel assembly. Utility Model Content
[0004] The purpose of the embodiments of the utility model is to provide an adapter salvaging tool and system to solve the technical problem in the prior art that the adapter is easy to fall off during the salvaging process.
[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: to provide an adapter salvage tool, including a guide member and a self-locking member, the self-locking member is rotatably connected to the guide member, the guide member is used to pass through the guide hole of the adapter, and after the guide member passes through the guide hole, the self-locking member can rotate relative to the guide member under the action of gravity and abut against the adapter.
[0006] In the above scheme, the adapter salvage tool includes a guide member and a self-locking member rotatably connected to the guide member. When the adapter needs to be salvaged, the guide member is extended into the guide hole of the adapter, and the self-locking member is automatically retracted to overlap with the guide member under the push of the adapter. After the self-locking member passes through the guide hole together with the guide member, the self-locking member rotates under the action of gravity and expands relative to the guide member. When the adapter salvage tool is lifted, the self-locking member presses against the adapter, so that the adapter and its salvage tool are lifted synchronously. The adapter salvage tool has a simple structure. When the salvage tool is used to lift the adapter, it is tightly abutted against the adapter, the structure is stable, and the adapter is not easy to fall off.
[0007] Optionally, the guide member has a receiving groove, and the guide member can be rotated to the inside of the receiving groove.
[0008] In the above solution, by providing a receiving groove on the guide member, the self-locking member can be accommodated inside the guide member without increasing the volume of the adapter salvage tool. In this way, when the adapter salvage tool passes through the through hole, the self-locking member can be hidden inside the guide member without affecting the adaptation of the guide member and the guide hole.
[0009] Optionally, the guide member includes a connecting portion, a hinge shaft and two hinge parts arranged at intervals, the two hinge parts are connected by the connecting portion, both ends of the hinge shaft are respectively connected to the two hinge parts, the self-locking member is rotatably connected to the guide member through the hinge shaft, and the two hinge parts and the connecting portion form the accommodating groove.
[0010] In the above scheme, by setting the guide member as two hinged parts, a connecting part and a hinge axis, a receiving groove is formed between the connecting part and the two hinged parts, and the hinge axis is also set in the receiving groove, so that the self-locking member is rotatably connected to the guide member and can be rotated to the inside of the receiving groove.
[0011] Optionally, a stop block is provided inside the accommodating groove, and the stop block is used to abut and limit at least one side of the self-locking member.
[0012] In the above solution, the stop block is provided to limit the rotation angle and rotation range of the self-locking member, thereby preventing the self-locking member from being out of position.
[0013] Optionally, the side of the stop block that abuts against the self-locking member is a limiting side, and when the guide member is in use, the angle between the limiting side and the vertical direction is 30 degrees to 60 degrees.
[0014] In the above scheme, the larger the angle between the limit side and the vertical direction, the closer the limit side is to the horizontal setting. Due to various reasons such as processing errors, the stop block has a poor stopping effect on the self-locking part, and the self-locking part easily passes over the stop block. The smaller the angle between the limit side and the vertical direction, the closer the limit side is to the vertical setting, and the smaller the structural space reserved for the self-locking part, resulting in design difficulties. Therefore, the angle between the limit side and the guide member is designed to be 30 degrees to 60 degrees.
[0015] Optionally, one end of the self-locking member away from the rotational connection between the self-locking member and the guide member has a cut-angle structure.
[0016] In the above solution, by providing a cut-angle structure at the rotating end of the self-locking member, the self-locking member can be prevented from interfering with the guide member during rotation, thereby preventing the self-locking member and the guide member from colliding with each other.
[0017] Optionally, a side of the self-locking member for abutting against the adapter is provided with a surface texture for increasing roughness.
[0018] In the above solution, by providing a surface texture on the abutting side of the self-locking member, the friction coefficient between the abutting side of the self-locking member and the adapter can be increased, thereby making the clamping of the self-locking member to the adapter more stable.
[0019] Optionally, the end of the guide member that is used to extend into the guide hole is conical.
[0020] In the above scheme, the guide member can smoothly enter the guide hole through the mutual cooperation and guidance between the cylindrical surface of the conical end and the guide hole.
[0021] Optionally, the guide member is provided with a hanging ear for hanging a rope.
[0022] In the above solution, by providing the lifting lug, the hanging rope can be hung on the lifting lug, and after the adapter salvaging tool sinks into the water, the adapter can be lifted by pulling the hanging rope.
[0023] The utility model also provides an adapter salvaging system, comprising a plurality of the above-mentioned adapter salvaging tools, each of which is used to pass through a corresponding guide hole of the adapter.
[0024] In the above scheme, the adapter salvage tool includes a guide member and a self-locking member rotatably connected to the guide member. When the adapter needs to be salvaged, the guide member is extended into the guide hole of the adapter, and the self-locking member is automatically retracted to overlap with the guide member under the push of the adapter. After the self-locking member passes through the guide hole together with the guide member, the self-locking member rotates under the action of gravity and expands relative to the guide member. When the adapter salvage tool is lifted, the self-locking member presses against the adapter, so that the adapter and its salvage tool are lifted synchronously. The adapter salvage tool has a simple structure. When the salvage tool is used to lift the adapter, it is tightly abutted against the adapter and has a stable structure. In particular, when multiple adapter salvage tools are used to salvage the adapter at the same time, the adapter is less likely to fall off. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0035] A large number of related components are needed during the operation of nuclear power plants, especially units using burnable poisons, which will use a large number of nuclear fuel-related component adapters in the early stage. Each adapter will occupy nine fuel assembly storage racks. The use of a large number of adapters will occupy too many racks, resulting in a reduction in the fuel storage capacity of the spent fuel pool. Therefore, the adapters need to be removed from the water before the storage racks are full.
[0036] There are generally two ways to remove the adapter from the water: one is to grab the adapter with a spent fuel long-handled tool, and then lift it to the new fuel elevator through a spent fuel crane, and then lift the adapter out of the water through the new fuel elevator. The tool lifting and elevator lifting both take a lot of time and effort, and there is also the risk of the adapter falling off the spent fuel long-handled tool, and the risk of the adapter getting stuck when the elevator lifts it; the second is to use a hook to remove the water. Although this method is fast, it has a higher risk of falling off than the first solution. Regardless of which method is used to remove the water, once the adapter falls off, it will hit the fuel assembly or the fuel storage grid. In the least, the fuel storage grid will be unusable, and in the worst case, it will cause a nuclear safety IOE event in which the fuel assembly is damaged. The unusable fuel assembly may affect the subsequent overhaul and lose the use efficiency of the fuel assembly.
[0037] In order to solve the above technical problems, the utility model proposes a new adapter salvaging tool, which includes a guide member 10 and a self-locking member 20, and the self-locking member 20 is rotatably connected to the guide member 10. When the adapter is salvaged, the guide member 10 passes through the guide hole of the adapter, and the self-locking member 20 is rotated and opened relative to the guide member 10 under the action of gravity. When the adapter salvaging tool is lifted upward, the self-locking member 20 abuts against the adapter, so that the adapter can be taken out of the water.
[0038] The adapter salvage tool provided in the embodiment of the utility model is now described. The adapter salvage tool is used to salvage the adapter, and the adapter has a plurality of guide holes. Specifically, after the adapter salvage tool is sunk into the water and connected with the guide holes of the adapter, the adapter salvage tool is lifted up to salvage the adapter.
[0039] Please also read Figure 1 and Figure 2 The adapter salvaging tool includes a guide member 10 and a self-locking member 20 , and the self-locking member 20 is rotatably connected to the guide member 10 .
[0040] The guide member 10 is used to pass through the guide hole of the adapter. The guide hole of the adapter has a radial direction and an axial direction. When the adapter is in use, the radial direction of the guide hole is horizontal or close to horizontal, and the axial direction of the guide hole is vertical or close to vertical. The guide member 10 also has a radial direction and an axial direction accordingly. When the guide member 10 is in use, the axial direction of the guide member 10 is the same as the axial direction of the guide hole. Among them, the size of the cross section of at least part of the guide member 10 is smaller than the cross section size of the guide hole, so that one end of the guide member 10 can pass through the guide hole.
[0041] The self-locking member 20 is used to abut against the adapter, so that the adapter salvage tool and the adapter can be lifted at the same time. When the adapter salvage tool is in use, the axial direction of the guide member 10 is parallel to or close to the vertical direction. In this state, after the guide member 10 passes through the guide hole, the self-locking member 20 will automatically rotate and open under the action of gravity, and the end of the self-locking member 20 away from its rotation connection can abut against the adapter, thereby driving the adapter to move upward.
[0042] Specifically, when salvaging the adapter, the adapter salvage tool is sunk into the water, the guide member 10 is inserted into the guide hole of the adapter, and under the push of the adapter, the self-locking member 20 rotates relative to the guide member 10 until it overlaps with the guide member 10, that is, the guide member 10 and the self-locking member 20 are inserted into the guide hole together until the self-locking member 20 completely passes through the guide hole. After the self-locking member 20 passes through the guide hole, under the action of gravity, the self-locking member 20 rotates relative to the guide member 10 to an open state, at which time, the self-locking member 20 and the guide member 10 are set at an angle. Then, the adapter salvage tool is lifted upward, and the end of the self-locking member 20 away from its rotating connection abuts against the adapter, and the guide member 10 is also stuck on the adapter. The adapter, the self-locking member 20, and the guide member 10 form a stable triangular support structure, so that the adapter can be stably stuck on the adapter salvage tool. Therefore, the adapter is not easy to fall off the adapter salvage tool.
[0043] The adapter salvage tool in the above embodiment includes a guide member 10 and a self-locking member 20 rotatably connected to the guide member 10. When the adapter needs to be salvaged, the guide member 10 is inserted into the guide hole of the adapter. The self-locking member 20 is automatically retracted to overlap with the guide member 10 under the push of the adapter. After the self-locking member 20 passes through the guide hole together with the guide member 10, the self-locking member 20 rotates under the action of gravity and expands relative to the guide member 10. When the adapter salvage tool is lifted, the self-locking member 20 presses against the adapter, so that the adapter and its salvage tool are lifted synchronously. The adapter salvage tool has a simple structure. When the adapter is lifted using the salvage tool, it is tightly abutted against the adapter, the structure is stable, and the adapter is not easy to fall off.
[0044] In some embodiments of the present invention, the cross section of the guide member 10 is circular. When the guide member 10 is inserted into the guide hole, there is no need to adjust the circumferential direction of the guide member 10. The guide member 10 only needs to be aligned with the guide hole in the axial direction to allow the guide member 10 to be inserted into the guide hole. The cross section of the guide hole can be circular, square, etc., as long as the guide member 10 can be inserted into the guide hole.
[0045] In some embodiments of the present invention, please refer to Figure 1 and Figure 2 The guide member 10 has a receiving groove 110, and the guide member 10 can be rotated to the inside of the receiving groove 110. The adapter salvage tool has an unfolded state and a folded state. When the salvage tool is in the unfolded state, the self-locking member 20 and the guide member 10 are arranged at an angle. When the salvage tool is in the folded state, the self-locking member 20 is located in the receiving groove 110 and overlaps with the guide member 10.
[0046] By providing the receiving groove 110 on the guide member 10, the self-locking member 20 can be accommodated inside the guide member 10 without increasing the volume of the adapter fishing tool. In this way, when the adapter fishing tool passes through the guide hole, the self-locking member 20 can be hidden inside the guide member 10 without affecting the adaptation of the guide member 10 and the guide hole.
[0047] Optionally, the guide hole and the guide member 10 have the same cross-sectional shape, which facilitates the guide member 10 to pass through the guide hole. For example, the guide hole and the guide member 10 have circular cross-sectional shapes.
[0048] In some embodiments of the present invention, please refer to Figure 1 and Figure 2The guide member 10 includes a connecting portion 12, a hinge shaft, and two hinge portions 11 disposed at intervals. The two hinge portions 11 are connected by the connecting portion 12. Both ends of the hinge shaft are respectively connected to the two hinge portions 11. The self-locking member 20 is rotatably connected to the guide member 10 through the hinge shaft. The two hinge portions 11 and the connecting portion 12 form a receiving groove 110. The two hinge portions 11 disposed at intervals form a receiving space. The connecting portion 12 connects one end of the two hinge portions 11. The hinge shaft connects the other ends of the two hinge portions 11. The hinge shaft passes through the self-locking member 20, so that the self-locking member 20 can rotate relative to the guide member 10. Specifically, the self-locking member 20 can rotate relative to the guide member 10 to the inside of the receiving groove 110, and can also rotate relative to the guide member 10 to be arranged at an angle with the guide member 10 (most of the guide member 10 is located outside the receiving groove 110).
[0049] By configuring the guide member 10 to include two hinged parts 11, a connecting part 12 and a hinge axis, a receiving groove 110 is formed between the connecting part 12 and the two hinged parts 11, and the hinge axis is also configured in the receiving groove 110, so that the self-locking member 20 is rotatably connected to the guide member 10 and can be rotated to the inside of the receiving groove 110.
[0050] In some embodiments, the hinge shaft is fixedly connected to the self-locking member 20 , and both ends of the hinge shaft are rotatably disposed on the two hinge parts 11 to achieve a rotatable connection between the self-locking member 20 and the guide member 10 .
[0051] In some embodiments, the hinge shaft is fixedly connected to the hinge portion 11 , and the self-locking member 20 is rotatably disposed on the hinge shaft to achieve a rotatable connection between the self-locking member 20 and the guide member 10 .
[0052] In some embodiments, see Figure 1 and Figure 2 The connecting portion 12 extends out of the circumferential surface of the guide member 10 in the radial direction of the guide member 10, so that the hinge portion 11 of the guide member 10 can extend into the guide hole, and the connecting portion 12 cannot enter the guide hole. The connecting portion 12 forms an axial movement positioning for the guide member 10.
[0053] In some embodiments, the connecting portion 12, the hinged portion 11, and the hinge shaft are all formed separately, and then the connecting portion 12 and the hinged portion 11 can be fixed to each other by welding to reduce the processing difficulty of the guide member 10 and save processing costs.
[0054] In some embodiments of the present invention, please refer to Figure 1 The receiving groove 110 is provided with a stopper 13, which is used to abut and limit at least one side of the self-locking member 20. When the self-locking member 20 rotates to abut against the stopper 13, the self-locking member 20 can no longer rotate, thereby forming a limit effect on the self-locking member 20. The stopper 13 is at least partially disposed inside the receiving groove 110. Figure 1 The stopping function of the stopper 13 is described below. When the guide member 10 extends into the guide hole, the self-locking member 20 is gradually accommodated in the receiving groove 110 under the push of the adapter until the self-locking member 20 abuts against the stopper 13. The stopper 13 prevents the self-locking member 20 from rotating counterclockwise to the left after entering the receiving groove 110, so that the rotation range of the self-locking member 20 is always located on the right side of the guide member 10.
[0055] By setting the stop block 13 , the rotation angle and rotation range of the self-locking member 20 can be limited to prevent the self-locking member 20 from being out of position.
[0056] In some embodiments, the stop block 13 is fixedly connected to the connecting portion 12. For example, the stop block 13 and the connecting portion 12 are welded and fixed to each other.
[0057] In some embodiments, the stop block 13 is fixedly connected to at least one hinged portion 11. For example, the stop block 13 is fixedly connected to the hinged portion 11 by welding.
[0058] In some embodiments of the present invention, please refer to Figure 1 The side of the stopper 13 that is used to abut against the self-locking member 20 is the limiting side 131. When the guide member 10 is in use, the angle between the limiting side 131 and the vertical direction is 30 to 60 degrees. When the adapter salvage tool is in use, the axial direction of the guide member 10 is parallel to the vertical direction, and the angle between the limiting side 131 and the axial direction of the guide member 10 is 30 to 60 degrees.
[0059] The larger the angle between the limiting side 131 and the vertical direction, the closer the limiting side 131 is to a horizontal setting. Due to various reasons such as processing errors, the stopping effect of the stop block 13 on the self-locking member 20 may be poor, and the self-locking member 20 may easily pass over the stop block 13. The smaller the angle between the limiting side 131 and the vertical direction, the closer the limiting side 131 is to a vertical setting, and the smaller the structural space reserved for the self-locking member 20, resulting in design difficulties. Therefore, the angle between the limiting side 131 and the guide member 10 is designed to be 30 degrees to 60 degrees.
[0060] In some embodiments, the angle between the limiting side 131 and the guide member 10 is 30 degrees, 35 degrees, 40 degrees, etc.
[0061] In other embodiments, the accommodating groove 110 is not provided on the guide member 10 , and the self-locking member 20 is provided outside the guide member 10 .
[0062] In some embodiments of the present invention, please refer to Figures 1 to 3The end of the self-locking member 20 away from the rotational connection between the self-locking member 20 and the guide member 10 has a cut-angle structure 22. The cut-angle structure 22 is arranged at the self-locking member 20 away from the rotational connection. The end of the self-locking member 20 away from the rotational connection between the self-locking member 20 and the guide member 10 is called the rotational end of the self-locking member 20. When the self-locking member 20 gradually rotates to the inside of the receiving groove 110, the corners of the rotational end of the self-locking member 20 are easy to collide with the guide member 10. Therefore, the cut-angle structure 22 can prevent the self-locking member 20 and the guide member 10 from colliding with each other.
[0063] By providing the cut-angle structure 22 at the rotating end of the self-locking member 20 , it is possible to avoid interference between the self-locking member 20 and the guide member 10 during rotation, thereby avoiding collision between the self-locking member 20 and the guide member 10 .
[0064] In some embodiments of the present invention, the side of the self-locking member 20 that is used to abut against the adapter is provided with a surface texture. The side of the self-locking member 20 that is used to abut against the adapter is the abutting side 21, and the abutting side 21 is provided with a surface texture. The setting of the surface texture can increase the surface roughness of the abutting side 21, thereby reducing the possibility of the self-locking member 20 sliding relative to the adapter, making the self-locking member 20 more stable in clamping the adapter.
[0065] By providing a surface texture on the abutting side 21 of the self-locking member 20 , the friction coefficient between the abutting side 21 of the self-locking member 20 and the adapter can be increased, thereby making the clamping of the self-locking member 20 to the adapter more stable.
[0066] In some embodiments, the surface texture may be surface protrusions or surface depressions, specifically, may be convex points, depressions, patterns, etc.
[0067] In some embodiments of the present invention, please refer to Figure 1 The end of the guide member 10 for inserting into the guide hole is conical. When installing the guide member 10 to the adapter, the conical end of the guide member 10 first inserts into the guide hole of the adapter, and the guide member 10 can smoothly enter into the guide hole through the mutual cooperation and guidance of the cylindrical surface of the conical end and the guide hole.
[0068] In some embodiments of the present invention, please refer to Figure 1 A lifting lug 14 for hanging a rope is provided on the guide member 10. The lifting lug 14 is fixedly connected to the guide member 10, and a hanging hole is formed between the lifting lug 14 and the guide member 10, so that the hanging rope can be hung on the hanging hole, which is convenient for controlling the adapter salvage tool.
[0069] By setting the lifting lug 14, a hanging rope can be hung on the lifting lug 14. After the adapter salvaging tool sinks into the water, the adapter can be lifted by pulling the hanging rope.
[0070] In some embodiments, the lifting ear 14 is fixedly connected to the connecting portion 12 of the guide member 10 .
[0071] In some embodiments, the lifting ear 14 is fixed to the guide member 10 by welding, and the welding fixing method is relatively reliable.
[0072] The utility model also provides an adapter salvage system, which includes the adapter salvage tool in any of the above embodiments. There are multiple adapter salvage tools, and each adapter salvage tool is used to pass through the corresponding guide hole of the adapter. Among them, the adapter is provided with multiple guide holes, and when the adapter salvage tools are clamped in some of the guide holes, the adapter can be more stable after coming out of the water, reducing the possibility of the adapter falling.
[0073] The adapter salvage system provided by the utility model adopts the above-mentioned adapter salvage tool. When the adapter needs to be salvaged, the guide member 10 is inserted into the guide hole of the adapter. The self-locking member 20 is automatically retracted to overlap with the guide member 10 under the push of the adapter. After the self-locking member 20 passes through the guide hole together with the guide member 10, the self-locking member 20 rotates under the action of gravity and unfolds relative to the guide member 10. When the adapter salvage tool is lifted, the self-locking member 20 presses against the adapter, so that the adapter and its salvage tool are lifted synchronously. The adapter salvage tool has a simple structure. When the adapter is lifted by the salvage tool, it is tightly abutted against the adapter and has a stable structure. In particular, when multiple adapter salvage tools are used to salvage the adapter at the same time, the adapter is less likely to fall off.
[0074] In some embodiments of the present invention, there are two adapter salvaging tools, and the two adapter salvaging tools are respectively matched with the guide holes at two diagonal positions of the adapter to salvage the adapter.
[0075] In some embodiments of the present invention, the number of the adapter salvaging tools is four, and the four adapter salvaging tools are respectively matched with the guide holes at the four corners of the adapter to salvage the adapter.
[0076] In some embodiments of the present invention, the adapter salvaging system further comprises a lanyard, which is hung on the guide member 10 , and the adapter salvaging tool can be lifted upward by pulling the lanyard.
[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
