Description

Technical Field

[0001] The invention belongs to the field of metal bellows forming, and in particular relates to a nuclear power metal hose working condition simulation test device. Background Art

[0002] Metal hoses, with their excellent flexibility, durability and sealing performance, play an irreplaceable role in the nuclear power industry. Specifically, they are manifested in the following aspects: The piping system of a nuclear power plant expands and contracts due to temperature changes during operation. As expansion joints, metal hoses can effectively absorb these displacements and prevent the piping system from being damaged due to stress concentration. At the same time, they can also effectively absorb mechanical vibrations and protect key equipment from vibration. When handling radioactive media or high-temperature and high-pressure fluids, metal hoses provide reliable sealing performance, ensuring that the internal media of the system will not leak and cause pollution or safety hazards to the external environment. Metal hoses are used as fluid transmission channels in nuclear fuel processing, coolant circulation and other systems. Their high corrosion resistance and temperature resistance ensure the safety and efficiency of fluid transmission. In emergency situations, such as earthquakes or accidents, the flexibility of metal hoses enables them to maintain system integrity in the event of structural deformation, ensuring the continued operation of critical systems.

[0003] Although metal hoses are widely used in the nuclear power field, their long-term reliability and safety are facing severe challenges. Most existing metal hose testing methods are based on static or simplified dynamic conditions and cannot truly simulate the complex and changeable actual working conditions of nuclear power plants, including but not limited to the influence of comprehensive factors such as temperature fluctuations, pressure changes, vibration frequency, and chemical corrosion.

[0004] In addition, traditional test tools are often bulky, complex to operate, and costly, and lack the ability to evaluate the long-term performance of metal hoses under extreme conditions, which limits the depth and breadth of their application in the nuclear power field.

[0040] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0041] like Figure 1-4 As shown, the present invention provides a nuclear power metal hose working condition simulation test device, which includes: a frame 1, a hose clamping device, and a torsion drive module 4.

[0042] The bottom of the frame 1 is provided with supporting feet for supporting the frame 1. The frame 1 is provided with a transverse guide rail 101 and a longitudinal guide rail 102, the longitudinal guide rail 102 is provided perpendicular to the frame 1, the transverse guide rail 101 is provided parallel to the frame 1, and the transverse guide rail 101 and the longitudinal guide rail 102 are mutually perpendicular structures. The frame 1 is provided with a hose clamping device for clamping the metal hose 7. The hose clamping device includes a transverse clamping block 2 and a longitudinal clamping block 3, wherein the transverse clamping block 2 is used to clamp one end of the metal hose 7, and the longitudinal clamping block 3 is used to clamp the other end of the metal hose 7. In this embodiment, the transverse clamping block 2 and the longitudinal clamping block 3 are both clamped at the connecting flange 71 of the metal hose 7.

[0043] A torsion drive module 4 is also provided on the frame 1. In this embodiment, the torsion drive module 4 is provided on the longitudinal guide rail 102 for connecting with the longitudinal clamping block 3 to drive the metal hose 7 clamped on the longitudinal clamping block 3 to twist.

[0044] like Figure 2 As shown, in this embodiment, the torsion drive module 4 includes a moving block 401 arranged on the longitudinal guide rail 102 of the frame 1, and a guide portion is arranged on the moving block 401. Through the cooperation between the guide portion and the longitudinal guide rail 102, the moving block 401 can move on the longitudinal guide rail 102. A first driving mechanism is arranged on the frame 1 and connected to the moving block 401. Through the action of the first driving mechanism, the moving block 401 can be driven to move up and down on the longitudinal guide rail 102. In this embodiment, the first driving mechanism adopts a lead screw slider mechanism, and the lead screw is driven to rotate by the motor, thereby driving the moving block 401 to slide up and down on the longitudinal guide rail 102.

[0045] A rotating motor 402 is also provided on the moving block 401, and the rotating motor 402 is connected to the longitudinal clamping block 3 through a rotating shaft 403. In this embodiment, the longitudinal clamping block 3 includes a first longitudinal clamping block 301 and a second longitudinal clamping block 302, and corresponding semicircular slots are provided on the first longitudinal clamping block 301 and the second longitudinal clamping block 302. The first longitudinal clamping block 301 and the second longitudinal clamping block 302 are connected through a guide rod and a cylinder, and the cylinder movement can drive the first longitudinal clamping block 301 and the second longitudinal clamping block 302 to open and close. The rotating shaft 403 is connected to the first longitudinal clamping block 301, and the rotating motor 402 rotates, driving the longitudinal clamping block 3 to rotate through the rotating shaft 403, thereby realizing a torsion test of the metal hose 7 clamped on the longitudinal clamping block 3. The first driving mechanism is operated to drive the moving block 401 to move up and down on the longitudinal guide rail 102, thereby driving the longitudinal clamping block 3 to move up and down, that is, the metal hose 7 clamped on the longitudinal clamping block 3 can be tested for movement in the longitudinal direction.

[0046] A locking rod is also provided on the moving block 401 and connected to the first longitudinal clamping block 301. Specifically, a plug hole 303 is provided on the first longitudinal clamping block 301, and a locking cylinder 404 is provided on the moving block 401. The piston rod of the locking cylinder 404 is connected to the locking rod, and the locking cylinder 404 can drive the locking rod to be inserted into or out of the plug hole 303. When the locking rod is inserted into the plug hole 303, the rotating motor 402 cannot drive the longitudinal clamping block 3 to rotate. When the locking rod is out of the plug hole 303, the rotating motor 402 can drive the longitudinal clamping block 3 to rotate.

[0047] like Figure 3 As shown, the transverse clamping block 2 includes a first transverse clamping block 201 and a second transverse clamping block 202, and corresponding semicircular clamping grooves are arranged on the first transverse clamping block 201 and the second transverse clamping block 202. The first transverse clamping block 201 and the second transverse clamping block 202 are connected by a guide rod and a cylinder, and the cylinder movement can drive the first transverse clamping block 201 and the second transverse clamping block 202 to open and close. When the cylinder drives the first transverse clamping block 201 and the second transverse clamping block 202 to open, at this time, one end of the metal hose 7 can be put in by utilizing the gap between the first transverse clamping block 201 and the second transverse clamping block 202, and then the cylinder drives the first transverse clamping block 201 and the second transverse clamping block 202 to close the mold, so that one end of the metal hose 7 (that is, the connection flange 71 of the metal hose 7) is clamped in the circular clamping groove formed by the two semicircular clamping grooves.

[0048] In this embodiment, in order to clamp multiple metal hoses 7 at one time, three semicircular slots are respectively provided on the first transverse clamping block 201 and the second transverse clamping block 202, thus forming three clamping stations, which can clamp three metal hoses 7 at the same time. Of course, three semicircular slots are also respectively provided on the first longitudinal clamping block 301 and the second longitudinal clamping block 302, so that the number of metal hoses 7 clamped on the transverse clamping block 2 corresponds to the number of metal hoses 7 clamped on the longitudinal clamping block 3.

[0049] The first transverse clamping block 201 is also provided with a guide portion that cooperates with the transverse guide rail 101. The cooperation between the guide portion and the transverse guide rail 101 enables the transverse clamping block 2 to move. The transverse clamping block 2 is connected to a second driving mechanism provided on the frame 1. The second driving mechanism can drive the transverse clamping block 2 to move on the transverse guide rail 101 of the frame 1. When the second driving mechanism stops, the transverse clamping block 2 remains in a locked state, that is, the position remains stable. In this embodiment, the second driving mechanism adopts a screw slider mechanism, which drives the screw rod to rotate through a motor, thereby driving the first transverse clamping block 201 to slide left and right on the transverse guide rail 101.

[0050] In another specific embodiment, a water supply module is further provided on the frame 1, and the water supply module is used to connect the interface of the metal hose 7 to supply water to the metal hose 7.

[0051] The water supply connector module 5 includes a connector fixing seat 501, a connector fixing seat driving mechanism 502, and a connector 503 arranged on the connector fixing seat 501. The connector fixing seat driving mechanism 502 is used to drive the connector fixing seat 501 to move. The movement of the connector fixing seat 501 can drive the connector 503 to be inserted into the interface at one end of the metal hose 7. The connector 503 is used to connect to the external water supply. In this embodiment, the connector fixing seat 501 is set on the longitudinal guide rail 102 of the frame 1. The connector fixing seat driving mechanism 502 adopts a longitudinal cylinder, which drives the connector fixing seat 501 to move on the longitudinal guide rail 102 through the longitudinal cylinder, and docks with the metal hose 7 on the longitudinal clamping block 3 to supply water to the metal hose 7.

[0052] The plug module 6 includes a plug fixing seat 601, a plug fixing seat driving mechanism 602 and a plug 603 on the plug fixing seat 601. The plug fixing seat 601 is set on the transverse guide rail 101 of the frame 1. The plug fixing seat driving mechanism 602 is used to drive the plug fixing seat 601 to move on the transverse guide rail 101. In this embodiment, the plug fixing seat driving mechanism 602 adopts a transverse cylinder. The transverse cylinder drives the plug fixing seat 601 to move, which can drive the plug 603 to be inserted into the interface at the other end of the metal hose 7 to complete the sealing of the metal hose 7 at this end.

[0053] In order to adapt the water supply module to metal hoses 7 of different sizes and specifications, and also to enable the water supply module to quickly dock with the metal hose 7, in this embodiment, the joint 503 of the water supply module includes a conical joint plug-in portion, on which a plurality of annular grooves of different diameters are arranged, and an annular sealing ring 9 is arranged on the annular groove. Figure 4 As shown, the plug 603 includes a conical plug connector, on which a plurality of annular grooves of different diameters are arranged, and an annular sealing ring 9 is arranged on the annular groove. The joint fixing seat 501 is driven to move by the longitudinal cylinder, so that the conical joint connector on the joint 503 is quickly inserted into the interface at one end of the metal hose 7, and a seal is quickly formed. The plug fixing seat 601 is driven to move by the transverse cylinder, so that the conical joint connector on the plug 603 is quickly inserted into the interface at the other end of the metal hose 7, and a seal is quickly formed. Finally, the external water supply pipe valve is opened to supply water to the metal hose 7, and a water pressure test is performed.

[0054] In another specific embodiment, the nuclear power metal hose working condition simulation test device further includes a sensor module, which includes a displacement sensor and an angle sensor arranged on the hose clamping device and a pressure sensor arranged on the water supply module. The horizontal clamping block 2 and the longitudinal clamping block 3 are both provided with a displacement sensor for recording the displacement of the metal hose 7, and the longitudinal clamping block 3 is also provided with an angle sensor for recording the twisting angle of the metal hose 7.

[0055] In another specific embodiment, in order to adapt to metal hoses of different sizes, a detachable clamping liner 8 is provided in the semicircular clamping groove. In this embodiment, the inner walls of the semicircular clamping grooves of the first longitudinal clamping block 301, the second longitudinal clamping block 302, the first transverse clamping block 201, and the second transverse clamping block 202 are also provided with mounting grooves, such as Figure 5 As shown, a protruding plug block 801 is provided on the outer wall of the clamping liner 8, and the plug block 801 can be inserted into the installation groove, so that the installation and fixation of the liner 8 is completed. When it is necessary to clamp metal hoses of different diameters, it is only necessary to replace the clamping liner 8 of different inner diameters, thereby ensuring the stability of the longitudinal clamping block 3 and the transverse clamping block 2 in clamping the metal hose.

[0056] The present invention is described in detail above with reference to the accompanying drawings and embodiments, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of ordinary technicians in the field without departing from the purpose of the present invention. The contents not described in detail in the present invention can adopt the existing technology.
