Description

Technical Field

[0001] This application relates to the field of magnetic measurement technology for light sources, and in particular to an advanced magnetic measurement chamber for light sources. Background Technology

[0002] An Advanced Light Source (ALS) is a third-generation synchrotron radiation source with an electromagnetic spectrum located in the X-ray region. ALS can achieve a brightness a billion times that of sunlight and is widely used in research in materials science, biology, chemistry, physics, and environmental science. However, using an ALS for magnetic field detection, such as that of storage ring magnets, requires very specific environmental conditions and typically necessitates conducting the work in a designated location.

[0003] Magnetic field testing using advanced light sources typically requires a constant temperature and humidity environment. To ensure that the temperature and humidity of the testing environment meet the testing requirements, advanced light source magnetic testing is usually conducted in a dedicated testing room equipped with high-power temperature and humidity control equipment. The constant temperature and humidity air generated by the temperature and humidity control equipment is continuously exchanged with the testing room to ensure that the temperature and humidity in the testing environment are maintained within the set range.

[0004] Magnetic testing of advanced light sources typically requires various testing equipment and multiple large-diameter magnetic field coils. Furthermore, the devices under test are usually quite large, necessitating a large testing chamber with a high ceiling. Moving the devices to their designated testing positions within the chamber often requires the installation of cranes or other hoisting equipment at higher elevations, further increasing the height requirements. Therefore, existing advanced light source testing chambers typically have high ceilings, resulting in a large internal space. This large space not only increases the workload of temperature and humidity control equipment and energy consumption but also reduces the stability of temperature and humidity within the chamber, affecting the accuracy of advanced light source magnetic testing. Summary of the Invention

[0005] To ensure the stability of the magnetic measurement environment for advanced light sources, this application provides an advanced light source magnetic measurement chamber.

[0006] The advanced light source magnetic measurement chamber provided in this application adopts the following technical solution:

[0007] An advanced light source magnetic measurement chamber includes a magnetic measurement room and a constant temperature room. The magnetic measurement room is equipped with advanced light source magnetic measurement equipment, and the constant temperature room is equipped with constant temperature and humidity equipment. The air outlet of the constant temperature and humidity equipment is located in the magnetic measurement room. A roof platform is provided on the side wall of the magnetic measurement room. At least two roof moving frames are provided on the roof platform. The roof moving frames can move on the roof platform, so that the roof moving frames are in a stacked state or a flat state. A roof is provided on the roof moving frames. The roof can be raised and lowered relative to the roof moving frames, so that the roof can isolate the space above and below the roof platform in the magnetic measurement room.

[0008] By adopting the above technical solution, at least two roof moving frames, which are movable and set on the roof platform, can move at least two roofs to a stacked or flat state on the roof platform. In the stacked state, the hoisting equipment above the roof platform is exposed, allowing the hoisting equipment to transfer large test equipment within the magnetic measurement chamber. In the flat state, the roofs can be used to partition the space above and below the roof platform, reducing the size of the magnetic measurement chamber and making it easier for the temperature and humidity control equipment to maintain the stability of temperature and humidity within the magnetic measurement chamber. Using roofs that rise and fall relative to the roof moving frames, the roofs can be controlled to descend when the roof moving frames are in the flat state, sealing the space inside the roof platform and forming a partition between the upper and lower spaces of the roof platform. Before the roof platform moves, the roofs can be controlled to rise to a position flush with the roof moving frames to prevent interference between the roofs during the roof platform movement.

[0009] In one specific implementation scheme, the roof movable frame includes a first movable frame and a second movable frame. Multiple traveling trolleys are provided on both sides of the first and second movable frames. A first track and a second track are respectively provided on the roof platform on both sides of the magnetic measurement room. The first track is located inside the second track. The first movable frame is supported on the first track by the traveling trolleys, and the second movable frame is supported on the second track by the traveling trolleys. The height of the first movable frame is lower than that of the second movable frame, so that the first movable frame and the second movable frame can slide alternately on the roof platform.

[0010] By adopting the above technical solution, multiple shaped trolleys are set below the sides of the first and second movable frames, enabling the first and second movable frames to move more smoothly on the first and second tracks respectively. Furthermore, by setting the first track inside the second track and the height of the first movable frame being lower than that of the second movable frame, interference is prevented when the first and second movable frames move in opposite directions.

[0011] In one specific implementation, the traveling trolley includes a traveling wheel frame, traveling wheels, a circumferential frame, a circumferential wheel axle, and circumferential wheels. The traveling wheel frame is fixed to the first or second movable frame. The traveling wheels are rotatably mounted on the traveling wheel frame and supported on the first or second track. The circumferential frame is fixed to the traveling wheel frame. The circumferential wheel axle is fixed to the circumferential frame and located on both sides of the traveling wheel's rotation axis. The circumferential wheels are rotatably mounted on the circumferential wheel axle and respectively abut against both sides of the first or second track.

[0012] By adopting the above technical solution, the position of the traveling wheels on the first or second track can be restricted by the ring wheels that abut against both sides of the first or second track, ensuring that the traveling wheels are reliably supported on the first or second track, improving the reliable support and stable movement of the first and second moving frames on the first and second tracks, and preventing the first and second moving frames from overturning during movement.

[0013] In one specific implementation scheme, a platform partition beam is provided in the middle of the roof platform. The platform partition beam divides the space between the roof platforms around the sidewall of the magnetic measurement room into a first roof space and a second roof space. The first roof space and the second roof space are the same size. The roof includes a first roof and a second roof. The first roof is installed on a first movable frame, and the second roof is installed on a second movable frame. Both the first roof and the second roof can enclose either the first roof space or the second roof space. A first driving mechanism and a second driving mechanism are provided at the platform partition beam. The first driving mechanism can drive the first movable frame to move on the first track, so that the first roof is located above the first roof space or above the second roof space. The second driving mechanism can drive the second movable frame to move on the second track, so that the second roof is located above the first roof space or above the second roof space.

[0014] By adopting the above technical solution, the first roof space and the second roof space formed by separating the inner space of the roof platform using the platform partition beam can better cooperate with the first and second roofs, forming an effective partition between the spaces above and below the roof platform. The platform partition beam, located in the middle of the roof platform, can also be used to install a drive mechanism for moving the first and second moving frames, enabling the drive mechanism to operate the first and second moving frames in a fixed position, ensuring the reliability and safety of the moving frame drive.

[0015] In one specific implementation scheme, the first drive mechanism includes a first drive motor, a double-head reducer, a first transmission shaft, a first inner drive seat, a first inner drive gear, a second transmission shaft, a second inner drive seat, and a second inner drive gear. The output shaft of the first drive motor is connected to the double-head reducer, which is fixed in the middle of the platform partition beam. The first inner drive seat and the second inner drive seat are respectively fixed on the platform partition beam at corresponding positions inside both sides of the first movable frame. A first drive rack and a second drive rack are respectively provided on both sides of the first movable frame. The first inner drive gear is rotatably mounted on the first inner drive seat and meshes with the first drive rack. The second inner drive gear is rotatably mounted on the second inner drive seat and meshes with the second drive rack. One end of the first transmission shaft is drivenly connected to the double-head reducer, and the other end is drivenly connected to the first inner drive gear. One end of the second transmission shaft is drivenly connected to the double-head reducer, and the other end is drivenly connected to the second inner drive gear.

[0016] By adopting the above technical solution, the double-head reducer drives the first internal drive gear to rotate through the first transmission shaft and the second internal drive gear to rotate through the second transmission shaft. Through the meshing between the internal drive gear and the drive rack, the first moving frame can be driven to move on the first track from the inside, and the consistency of the driving force and driving speed on both sides of the first moving frame can be ensured, thus ensuring the smooth movement of the first moving frame.

[0017] In one specific implementation, the second drive mechanism includes a geared motor, an external drive base, an external drive gear, and a gear encoder. The external drive base is fixed on the outer side of the second movable frame on the roof platform, opposite to the platform partition beam. Side racks are provided on both sides of the second movable frame. The external drive gear is rotatably mounted on the external drive base and meshes with the side racks. The geared motor is driven by the external drive gear, and the gear encoder is mounted on the rotating shaft of the external drive gear.

[0018] By adopting the above technical solution, the geared motor connected to the external drive gear can drive the second moving frame to move on the second track through the meshing between the external drive gear and the side rack. Using a gear encoder mounted on the external drive gear, the rotational position of the external drive gear can be sensed, thereby enabling cross-control of the rotational speed of the geared motors on other second drive mechanisms. This ensures the consistency of the rotational speed of the external drive gears on each second drive mechanism, and consequently, the consistency of the movement amplitude on both sides of the second moving frame.

[0019] In one specific implementation scheme, multiple lifting drive mechanisms are symmetrically arranged between the roof moving frame and the roof. Each lifting drive mechanism includes a lifting drive base, a lifting winch, a lifting drive motor, and a lifting traction cable. The lifting drive base is fixed on the roof moving frame. The lifting winch is rotatably mounted on the lifting drive base, with at least one side located above the roof. The lifting drive motor is driven by the lifting winch. One end of the lifting traction cable is wound around the lifting winch, and the other end is fixed to the roof.

[0020] By adopting the above technical solution, a lifting winch, which is rotatably mounted on the lifting drive seat and has at least one side located above the roof, can pull the lifting traction cable to drive the roof to rise and fall on the roof moving frame, so that the roof rises to a position level with the roof moving frame, or falls to a position level with the roof platform.

[0021] In one specific implementation, the lifting drive mechanism further includes a locking wheel and a locking device. The locking wheel is fixed on the rotating shaft of the lifting winch and located on the outside of the lifting drive base. Multiple locking grooves are evenly distributed around the outer periphery of the locking wheel. The locking device is fixed on the side of the locking wheel on the lifting drive base. The locking device includes a locking housing, a locking electromagnet, a locking armature, a locking spring, and a locking head. The locking housing is fixed on the lifting drive base. The locking armature is disposed within the locking housing and can slide under the drive of the locking electromagnet. Multiple spring grooves are provided on the outer periphery of the portion of the locking armature adjacent to the locking electromagnet. A spring support block corresponding to the spring groove is provided on the locking housing. The locking spring is disposed in the spring groove and supported between one end of the spring groove and the spring support block. One end of the locking head is fixed to the locking armature, and the other end protrudes from the locking housing and is disposed opposite to the outer periphery of the locking wheel. The power supply of the locking electromagnet is connected to the power supply of the lifting drive motor.

[0022] By adopting the above technical solution, using a locking wheel mounted on the rotating shaft of the lifting winch and a locking device fixed to the side of the locking wheel, the locking wheel can be locked in place by the locking device. This allows the roof to be locked in the event of a power outage or other unexpected situation, preventing accidental raising or lowering of the roof. The power supply of the locking electromagnet is connected to the power supply of the lifting drive motor. This allows the locking head to disengage from the locking slot while the lifting drive motor is operating, ensuring that the locking device does not affect the lifting and lowering of the roof. When the lifting drive motor stops operating, the locking device is in the locked state, ensuring that the locking head is engaged in the locking slot, locking the roof in a fixed lifting position.

[0023] In one specific implementation scheme, a lifting and limiting mechanism is further provided between the roof moving frame and the roof. The lifting and limiting mechanism includes a moving frame fixing plate, a fixed sliding column, a first sliding sleeve, a second sliding sleeve, and a cover-in sliding sleeve. The moving frame fixing plate is fixed to the top of the roof moving frame, and its inner end is located above the roof. The upper end of the fixed sliding column is fixed to the inner end of the moving frame fixing plate. The first sliding sleeve is sleeved on the fixed sliding column and slidably connected to the fixed sliding column. The second sliding sleeve is sleeved on the first sliding sleeve and slidably connected to the first sliding sleeve. The cover-in sliding sleeve is nested and fixed inside the roof. The second sliding sleeve is slidably installed in the cover-in sliding sleeve. Anti-detachment limiting structures are provided between the fixed sliding column and the first sliding sleeve, between the first sliding sleeve and the second sliding sleeve, and between the second sliding sleeve and the cover-in sliding sleeve.

[0024] By adopting the above technical solution, using the fixed sliding column fixed on the roof moving frame, the cover sliding sleeve set in the roof, and the first and second sliding sleeves slidably connected between the fixed sliding column and the cover sliding sleeve, it is possible to support the lifting and lowering of the roof while limiting the lateral position of the roof during the lifting and lowering process. This ensures that the roof can be located inside the roof moving frame when it is rising, and can accurately fill the first or second roof space when it is falling, thus ensuring the separation between the first and second roof spaces.

[0025] In one specific implementation, the roof is provided with a plurality of lighting holes, each lighting hole is provided with a lighting lamp, and the opening of the lighting hole is provided with a light-transmitting lampshade.

[0026] By adopting the above technical solution, the lighting lamps installed in multiple lighting holes can illuminate the magnetic measurement chamber after the roof partitions the space inside the roof platform, and can avoid the lighting lamps occupying the space inside the magnetic measurement chamber, thereby further compressing the space inside the magnetic measurement chamber under the roof.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] By setting a roof platform at a lower position on the side wall of the magnetic measurement chamber, and by moving the roof moving frame on the roof platform and raising and lowering the roof on the roof moving frame, the roof moving frame can be moved to expose the hoisting equipment at high altitude in the magnetic measurement chamber when it is necessary to hoist the equipment to be tested. This facilitates the transfer, installation and debugging of large equipment in the magnetic measurement chamber. When it is necessary to test the equipment, the roof can be moved so that the roof isolates the space above and below the roof platform. This allows the temperature and humidity control equipment to maintain a constant temperature and humidity in only the small space below the roof, reducing the workload of the temperature and humidity control equipment and improving the stability of temperature and humidity in the magnetic measurement chamber.

[0029] By setting up circumferential wheels on both sides of the traveling wheels that abut against both sides of the track, the support position of the traveling wheels can be restricted when they move on the track, ensuring the stability and position of the roof mobile frame when it moves on the roof platform, and preventing the roof mobile frame from overturning off the track due to unexpected forces during the movement.

[0030] By setting a first driving mechanism on the inner side of the first movable frame and a second driving mechanism on the outer side of the second movable frame on the platform partition beam, the first movable frame and the second movable frame can be driven to move alternately on the roof platform by the driving mechanism set in a fixed position. This allows the first movable frame and the second movable frame to move to a state of overlapping or flatness, ensuring the stability and safety of the movement and preventing interference between the first movable frame and the second movable frame during the alternate movement.

[0031] By using a dual-head reducer to drive the first moving frame from both sides simultaneously, and a gear encoder mounted on the outer drive gear, the balance of driving force and driving speed on both sides of the first and second moving frames can be ensured, thus guaranteeing the smooth movement of the first and second moving frames on the first and second tracks respectively.

[0046] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0047] The terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as “first” or “second” may explicitly or implicitly include one or more of the stated features.

[0048] In this application, unless otherwise stated, the directional terms such as "inner side" and "outer side" indicate the orientation or positional relationship based on the center position of the advanced light source magnetic measurement chamber of this application. Specifically, "inner side" refers to the orientation close to the center of the advanced light source magnetic measurement chamber, and "outer side" refers to the orientation away from the center of the advanced light source magnetic measurement chamber. The description of the orientation or positional relationship of the advanced light source magnetic measurement chamber and its internal structure in this application is consistent with its actual installation orientation during use.

[0049] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0050] One embodiment of the advanced light source magnetic measurement chamber of this application, such as Figures 1 to 4 As shown, the system includes a magnetic testing room 1 and a constant temperature room 2. The constant temperature room 2 is located adjacent to the magnetic testing room 1 and is connected to the magnetic testing room 1 by a sealed door. An advanced light source magnetic testing device is installed in the magnetic testing room 1, and a constant temperature and humidity device 21 is installed in the constant temperature room 2. The constant temperature and humidity device 21 is connected to the magnetic testing room 1 through an air supply duct 22. The constant temperature and humidity air generated by the constant temperature and humidity device 21 is continuously delivered to the magnetic testing room 1 through multiple air outlets to maintain the constant temperature and humidity of the air inside the magnetic testing room 1.

[0051] To ensure the hoisting and transport of large testing equipment within the magnetic testing room 1, the roof height of the room is typically quite high, reaching 17 meters in one actual construction project. This allows for the installation of large overhead cranes and other hoisting equipment at a higher position inside the room, facilitating the transport of large testing equipment within and outside the room. However, this also results in a very large interior space for the magnetic testing room 1, significantly increasing the burden on the temperature and humidity control equipment 21 and making it more difficult to maintain constant temperature and humidity levels. The magnetic testing room 1 can be a standalone building or formed by constructing a wall partition within another large building. Roof platforms 11 are installed on the surrounding walls of the magnetic testing room 1, typically positioned 3-4 meters above the ground. This ensures sufficient space for staff movement and a comfortable working environment while reducing the height of the interior space during magnetic testing operations, thus reducing the workload of the temperature and humidity control equipment 21 and improving the temperature and humidity control effect within the magnetic testing room 1.

[0052] Two roof-moving frames 3 are installed on the roof platform 11. The roof-moving frames 3 are typically rectangular frame structures. The two roof-moving frames 3 are supported on the roof platform 11 at opposite side walls inside the magnetic testing room 1, and can move on the roof platform 11, so that the roof-moving frames 3 are either overlapping each other or flatly covering the inner space of the roof platform 11. By moving the roof-moving frames 3 to the overlapping state, part of the inner space of the roof platform 11 is open, allowing for the transfer of large equipment to be tested inside and outside the magnetic testing room 1 using high-altitude hoisting equipment. Before performing advanced light source magnetic testing on the equipment to be tested, moving the roof-moving frames 3 to the flatly covering the inner space of the roof platform 11 isolates the vertical space of the roof platform 11, effectively reducing the size of the space inside the magnetic testing room 1 where the advanced light source magnetic testing equipment is located, reducing the workload of the constant temperature and humidity equipment 21, and improving the constant temperature and humidity effect inside the magnetic testing room 1.

[0053] A roof 4 is mounted on the roof moving frame 3, and the roof 4 can be raised and lowered relative to the roof moving frame 3 under the drive of the drive mechanism. When the roof 4 rises, it can be close to the roof moving frame 3 or located in the inner space of the roof moving frame 3, so that the two roofs 4 can move with the corresponding roof moving frame 3 without interfering with each other. When the roof 4 falls, both roofs 4 can be lowered to a height equivalent to the roof platform 11, and the two roofs 4 can cooperate to seal the space inside the roof platform 11 around the magnetic measurement room 1, thereby isolating the space above and below the roof platform 11 inside the magnetic measurement room 1. The air outlet of the constant temperature and humidity equipment 21 is located inside the magnetic measurement room 1 below the roof platform 11. After the roof 4 isolates the space, the internal space of the magnetic measurement room 1 is significantly reduced, thereby effectively improving the constant temperature and humidity effect inside the magnetic measurement room 1 when the advanced light source magnetic measurement equipment is working, and reducing the energy consumption of the constant temperature and humidity equipment 21.

[0054] In some embodiments of the advanced light source magnetic measurement chamber of this application, such as Figures 1 to 4 As shown, there are two roof moving frames 3, namely a first moving frame 31 and a second moving frame 32. Multiple support rods are evenly arranged on both sides of the first moving frame 31 and the second moving frame 32, and a traveling trolley 33 is fixed to the bottom of each support rod. The traveling trolley 33 can be any device suitable for moving on a track.

[0055] On the two longer roof platforms 11 of the magnetic testing room 1, a first track 111 and a second track 112 are respectively installed. The first track 111 and the second track 112 are arranged parallel to each other, with the first track 111 located inside the second track 112, that is, on the side away from the wall of the magnetic testing room 1. The first movable frame 31 is supported on the first track 111 by a traveling trolley 33, and the second movable frame 32 is supported on the second track 112 by the traveling trolley 33, so that the first movable frame 31 can move along the first track 111 and the second movable frame 32 can move along the second track 112.

[0056] The outer length of the first movable frame 31 in the direction perpendicular to the first track 111 is less than the inner length of the second movable frame 32 in the direction perpendicular to the second track 112, and the top height of the first movable frame 31 is lower than the bottom height of the second movable frame 32, so that the first movable frame 31 and the second movable frame 32 can slide alternately on the roof platform 11, forming a... Figure 1 and Figure 4 The overlapping shown, or as Figure 2 and Figure 3 The image shows the unfolded and tiled surface.

[0057] like Figure 12As shown, multiple constant temperature air vents 113 are installed on the roof platform 11. An air supply duct 22, connected to the constant temperature and humidity equipment 21, is located above the roof platform 11 and is connected to the constant temperature air vents 113. Constant temperature and humidity air output from the constant temperature and humidity equipment 21 continuously enters the magnetic measurement room 1 through the constant temperature air vents 113, maintaining a constant temperature and humidity within the magnetic measurement room 1 during the testing process.

[0058] In a preferred embodiment of the advanced light source magnetic measurement chamber of this application, such as Figure 5 As shown, the traveling trolley 33 includes a traveling wheel frame 331, traveling wheels 332, a circumferential frame 333, a circumferential wheel axle 334, and circumferential wheels 335. The traveling wheel frame 331 is fixed to the bottom of the support rod of the first moving frame 31 or the second moving frame 32. An installation space with an opening on the bottom surface is provided inside the traveling wheel frame 331. The traveling wheel 332 is rotatably installed in this installation space through a rotating shaft, so that one edge of the traveling wheel 332 is located outside the bottom surface of the traveling wheel frame 331, and is thus supported on the first track 111 or the second track 112.

[0059] A retaining frame 333 is fixed to one side of the traveling wheel frame 331. Two retaining wheel axles 334 are fixed to the bottom surface of the retaining frame 333, and the two retaining wheel axles 334 are located on both sides of the rotation axis of the traveling wheel 332. When the traveling wheel 332 is supported on the first track 111 or the second track 112, the two retaining wheel axles 334 are located on both sides of the first track 111 or the second track 112. Retaining wheels 335 are rotatably mounted on the retaining wheel axles 334, so that the two retaining wheels 335 abut against both sides of the first track 111 or the second track 112. When the traveling trolley 33 moves on the first track 111 or the second track 112, the two circumferential wheels 335 form a ring around the first track 111 or the second track 112 from both sides, restricting the support position of the traveling wheels 332 on the first track 111 or the second track 112, preventing the traveling wheels 332 from derailing or overturning during the travel process, improving the ability to adapt to track deformation, and ensuring the stable and reliable movement of the roof moving frame 3 on the roof platform 11.

[0060] Some of the traveling trolleys 33 may only include the traveling wheel frame 331 and the traveling wheel 332, without the ring frame 333, the ring wheel axle 334 and the ring wheel 335. This simplifies the structure of some of the traveling trolleys 33, while the adjacent traveling trolleys 33 can be used to prevent derailment and overturning.

[0061] In another preferred embodiment of the advanced light source magnetic measurement chamber of this application, such as Figure 6 and Figure 7As shown, a platform partition beam 12 is provided in the middle of the roof platform 11 along its length. The platform partition beam 12 is set perpendicular to the first track 111 and the second track 112, dividing the space between the roof platforms 11 around the side wall of the magnetic measurement room 1 into a first roof space and a second roof space of the same size and shape. The first moving frame 31 and the second moving frame 32 are both set as square frames, with rectangular frames of the same size inside for storage. When the first moving frame 31 and the second moving frame 32 are moved to the fully overlapped state or the maximum unfolded state, one edge of the first moving frame 31 and the second moving frame 32 always overlaps above the platform partition beam 12.

[0062] A first driving mechanism 34 and a second driving mechanism 35 are provided on the platform partition beam 12. The first driving mechanism 34 is located between the platform partition beam 12 and the first movable frame 31, and can drive the first movable frame 31 to move on the first track 111, so that the first movable frame 31 can move to any position between the top of the first roof space and the top of the second roof space. The second driving mechanism 35 is located between the platform partition beam 12 and the second movable frame 32, and can drive the second movable frame 32 to move on the second track 112, so that the second movable frame 32 can move to any position between the top of the first roof space and the top of the second roof space.

[0063] The roof 4 includes a first roof 41 and a second roof 42. The first roof 41 and the second roof 42 are the same size and shape, and are adapted to the first roof space and the second roof space respectively. The first roof 41 is mounted on the first movable frame 31 and can be raised and lowered on the first movable frame 31. By raising the first roof 41, the first roof 41 can be stored in the frame storage space inside the first movable frame 31, avoiding interference between the first roof 41 and the external structure during the movement of the first movable frame 31. When the first movable frame 31 moves to a position where the first roof 41 is directly above the first roof space or the second roof space, the first roof 41 is controlled to descend to a position flush with the roof platform 11, so that the first roof 41 is located in the first roof space or the second roof space, thus sealing the roof space.

[0064] The second roof 42 is mounted on the second movable frame 32 and can be raised and lowered on the second movable frame 32. By raising the second roof 42, it can be stored in the frame's internal storage space inside the second movable frame 32, avoiding interference between the second roof 42 and the external structure during the movement of the second movable frame 32. When the second movable frame 32 moves to a position where the second roof 42 is located directly above the first roof space or the second roof space, the second roof 42 is lowered to a position flush with the roof platform 11, thus placing the second roof 42 within the first roof space or the second roof space and sealing the roof space.

[0065] When the first movable frame 31 and the second movable frame 32 are in their maximum extended state, and the first roof 41 and the second roof 42 are simultaneously controlled to descend, the first roof 41 and the second roof 42 can each close one of the first roof space and the second roof space, forming a partition between the upper and lower spaces of the roof platform 11 inside the magnetic measurement room 1.

[0066] As one specific embodiment of the advanced light source magnetic measurement chamber in this application, such as Figure 5 and Figure 6 As shown, the first drive mechanism 34 includes a first drive motor 341, a double-head reducer 342, a first transmission shaft 343, a first inner drive seat 344, a first inner drive gear 345, a second transmission shaft 346, a second inner drive seat 347, and a second inner drive gear 348. The double-head reducer 342 is fixed in the middle of the platform partition beam 12. The first drive motor 341 can be fixed on the platform partition beam 12 and the double-head reducer 342. The output shaft of the first drive motor 341 is connected to the input shaft of the double-head reducer 342. The double-head reducer 342 has two output shafts respectively arranged on opposite sides of it. The two output shafts are respectively connected to the first transmission shaft 343 and the second transmission shaft 346 through universal couplings.

[0067] The first inner drive seat 344 and the second inner drive seat 347 are respectively fixed to corresponding positions inside the support rods on both sides of the first movable frame 31 on the platform partition beam 12. A first drive rack 311 and a second drive rack 312 are respectively provided at corresponding positions inside the support rods on both sides of the first movable frame 31. The first inner drive seat 344 and the second inner drive seat 347 are respectively fixed below the first drive rack 311 and below the second drive rack 312. A first inner drive gear 345 is rotatably mounted on the first inner drive seat 344 and meshes with the first drive rack 311; a second inner drive gear 348 is rotatably mounted on the second inner drive seat 347 and meshes with the second drive rack 312. The rotating shaft of the first inner drive gear 345 is connected to the other end of the first transmission shaft 343 via a universal coupling, and the second inner drive gear 348 is connected to the other end of the second transmission shaft 346 via a universal coupling. By controlling the rotation of the first drive motor 341, driving force can be generated synchronously on both sides of the first moving frame 31, driving the first moving frame 31 to move evenly and smoothly on the first tracks 111 on both sides.

[0068] An internal rack pressure roller 349 is provided above the first drive rack 311 on the first internal drive seat 344 and above the second drive rack 312 on the second internal drive seat 347. The internal rack pressure roller 349 is mounted on the first internal drive seat 344 or the second internal drive seat 347 via a fixed shaft and can rotate on the fixed shaft. The internal rack pressure roller 349 on the first internal drive seat 344 abuts against the side of the first drive rack 311 opposite to the first internal drive gear 345, and the internal rack pressure roller 349 on the second internal drive seat 347 abuts against the side of the second drive rack 312 opposite to the second internal drive gear 348. The internal rack pressure roller 349 ensures reliable meshing between the first internal drive gear 345 and the first drive rack 311, and between the second internal drive gear 348 and the second drive rack 312, ensuring reliable and stable drive of the first drive mechanism 34 to the first moving frame 31.

[0069] As another specific embodiment of the advanced light source magnetic measurement chamber of this application, such as Figure 7 and Figure 9 As shown, there are two second drive mechanisms 35, which are respectively installed on the roof platform 11 on both sides of the platform partition beam 12 and located outside the second moving frame 32.

[0070] The second drive mechanism 35 includes a geared motor 351, an outer drive base 352, an outer drive gear 353, and a gear encoder 354. The outer drive base 352 is fixed to the roof platform 11 outside the second movable frame 32. The geared motor 351 is fixedly mounted on the outer drive base 352, with its output shaft passing through it. The outer drive gear 353 is fixed to the output shaft of the geared motor 351 within the outer drive base 352. The gear encoder 354 is fixed to the output shaft of the geared motor 351 and located outside the outer drive base 352. Side racks 321 are fixed to the outer sides of the support rods on both sides of the second movable frame 32, and the outer drive gear 353 meshes with the side racks 321.

[0071] By controlling the rotation of the geared motor 351, the second moving frame 32 can be driven to move on the second track 112 through the meshing between the external drive gear 353 and the side rack 321. The gear encoder 354 can detect the actual rotation angle of the external drive gear 353, and coordinate the speed of the geared motors 351 on both sides of the second drive mechanism 35 according to the detection result, so as to ensure the synchronous rotation of the external drive gears 353 on both sides of the second drive mechanism 35, and ensure the smooth movement of the second moving frame 32. An external rack pressure roller 355 can also be provided on the external drive base 352. The external rack pressure roller 355 is mounted on the external drive base 352 through a fixed shaft and can rotate on the fixed shaft. The external rack pressure roller 355 abuts against the side of the side rack 321 opposite to the external drive gear 353. The external rack pressure roller 355 can ensure reliable meshing between the external drive gear 353 and the side rack 321, and ensure reliable and stable drive of the second moving frame 32 by the second drive mechanism 35.

[0072] In some embodiments of the advanced light source magnetic measurement chamber of this application, such as Figure 1 and Figure 10 As shown, multiple lifting drive mechanisms 5 are symmetrically arranged between the roof moving frame 3 and the roof 4. Each lifting drive mechanism 5 includes a lifting drive base 51, a lifting winch 52, a lifting drive motor 53, and a lifting traction cable 54. The lifting drive base 51 is fixed to the top surface of the roof moving frame 3 near one edge of the roof 4. The lifting winch 52 is rotatably mounted on the lifting drive base 51, with at least one edge of the lifting winch 52 positioned above the inner side of the roof moving frame 3 and above the roof 4. The lifting drive motor 53 typically includes a reduction gear, which connects to the rotation shaft of the lifting winch 52, enabling the lifting winch 52 to rotate.

[0073] One end of the lifting traction cable 54 is wound around the lifting winch 52, and the other end is fixed to the roof 4. By rotating the lifting winch 52, the length of the lifting traction cable 54 between the lifting winch 52 and the roof 4 can be changed, thereby pulling the roof 4 up and down relative to the roof moving frame 3. Multiple lifting drive mechanisms 5 operate synchronously, which can pull the roof 4 up and down synchronously from different parts of the roof 4, so that the roof 4 always remains in a horizontal state during the lifting process, ensuring the smooth operation of the lifting action of the roof 4 and the reliable sealing of the roof 4 to the inner roof space of the roof platform 11.

[0074] In a preferred embodiment of the advanced light source magnetic measurement chamber of this application, such as Figure 10 and Figure 11As shown, the lifting drive mechanism 5 also includes a locking wheel 55 and a locking device 56. The locking wheel 55 is fixed on the rotating shaft of the lifting winch 52 and is located on the outside of the lifting drive base 51, so that the locking wheel 55 rotates and stops synchronously with the lifting winch 52. The locking device 56 is fixed on the lifting drive base 51 and is arranged perpendicular to the outer peripheral surface of the locking wheel 55. The locking device 56 can brake the outer peripheral surface of the locking wheel 55, thereby locking the lifting winch 52 in the current position when the lifting drive motor 53 stops working.

[0075] Specifically, the locking device 56 includes a locking housing 561, a locking electromagnet 562, a locking armature 563, a locking spring 564, and a locking head 565. The locking housing 561 is fixed to the lifting drive seat 51. The locking armature 563 is disposed inside the locking housing 561 and can slide radially along the locking wheel 55 within the locking housing 561. The locking electromagnet 562 is disposed inside the locking housing 561 on the side of the locking armature 563 away from the locking wheel 55. When the power supply to the locking electromagnet 562 is turned on, it can attract the locking armature 563 to slide towards the locking electromagnet 562.

[0076] Multiple spring slots are symmetrically arranged on the outer peripheral surface of the locking armature 563, adjacent to the locking electromagnet 562. One end of each spring slot is closed, and the other end penetrates the end face of the locking armature 563. Multiple spring support blocks corresponding to the spring slots are provided on the locking housing 561. Locking springs 564 are respectively disposed in each spring slot, with both ends of the locking springs 564 supported between the end faces of the spring slots and the spring support blocks. Under the action of the locking springs 564, the locking armature 563 tends to move away from the locking electromagnet 562.

[0077] One end of the locking head 565 is fixed to the locking armature 563, and the other end protrudes from the locking housing 561 and is positioned opposite to the outer circumferential surface of the locking wheel 55. The locking head 565 and the locking armature 563 can be separately machined and then connected to each other by a suitable method, or they can be an integral structure machined from the same material. Under the action of the locking spring 564, the locking head 565 can move towards the locking wheel 55 together with the locking armature 563. Multiple locking grooves 551 are evenly arranged on the outer circumferential surface of the locking wheel 55, and the locking head 565 can engage with the locking grooves 551 to restrict the rotation of the locking wheel 55.

[0078] The power supply of the locking electromagnet 562 is connected to the power supply of the lifting drive motor 53. When the roof 4 needs to be lifted, the system controls the power supply of the lifting drive motor 53 to be turned on. At this time, the power supply simultaneously supplies power to the locking electromagnet 562. The locking electromagnet 562 attracts the locking armature 563 to move towards the locking electromagnet 562, causing the locking head 565 to disengage from the locking groove 551, ensuring that the lifting winch 52 can rotate freely and drive the roof 4 to lift. When the roof 4 is lifted to the set position, the system controls the power supply of the lifting drive motor 53 to be turned off, and the power supply to the locking electromagnet 562 stops at the same time. The locking armature 563 moves towards the locking wheel 55 under the action of the locking spring 564. The locking head 565 inserts into the locking groove 551 or abuts against the outer circumference of the locking wheel 55. With the slight rotation of the locking wheel 55, it inserts into the locking groove 551, thereby restricting the rotation of the lifting winch 52 and ensuring that the roof 4 is stably stopped at the set position.

[0079] In another preferred embodiment of this application, such as Figure 1 and Figure 12 As shown, a lifting and limiting mechanism 6 is also provided between the roof moving frame 3 and the roof 4. The lifting and limiting mechanism 6 includes a moving frame fixing plate 61, a fixing slide column 62, a first sliding sleeve 63, a second sliding sleeve 64, and a cover sliding sleeve 65. The moving frame fixing plate 61 is fixed to the top of the roof moving frame 3, and the inner end of the moving frame fixing plate 61 extends directly above the roof 4. The moving frame fixing plate 61 is usually fixed at a predetermined height above the top surface of the roof moving frame 3, thereby reserving sufficient height space between the moving frame fixing plate 61 and the roof 4.

[0080] The upper end of the fixed sliding column 62 is fixed to the lower inner end of the movable frame fixing plate 61. The first sliding sleeve 63 is sleeved on the fixed sliding column 62, forming a sliding connection with the fixed sliding column 62. The second sliding sleeve 64 is sleeved on the first sliding sleeve 63, forming a sliding connection with the first sliding sleeve 63. The cover sliding sleeve 65 is nested and fixed inside the roof 4. The lower end of the second sliding sleeve 64 is installed in the cover sliding sleeve 65, forming a sliding connection with the cover sliding sleeve 65. Anti-detachment limiting structures are provided between the fixed sliding column 62 and the first sliding sleeve 63, between the first sliding sleeve 63 and the second sliding sleeve 64, and between the second sliding sleeve 64 and the cover sliding sleeve 65 to prevent them from detaching from each other.

[0081] The lifting limit mechanism 6 can reduce the swaying of the roof 4 when it is suspended on the lifting traction cable 54, and ensure that the roof 4 can accurately enter the frame storage space inside the roof moving frame 3 and the first roof space or the second roof space between the roof platform 11.

[0082] In some embodiments of the advanced light source magnetic measurement chamber of this application, such as Figure 13As shown, multiple lighting holes 43 are provided on the lower side of the roof 4, the number of which is sufficient to meet the lighting requirements of the magnetic testing room 1. A lighting lamp 431 is installed in each lighting hole 43, and the lighting lamp 431 is located at the bottom of the lighting hole 43. A light-transmitting lampshade 432 is provided at the opening of the lighting hole 43, and the light-transmitting lampshade 432 is flush with the lower surface of the roof 4.
