Description

Technical Field

[0001] The present invention relates to the technical field of three-dimensional water tanks, in particular to a three-dimensional water tank with an attached three-coordinate adjustment system. Background Art

[0002] In the fields of radiotherapy, medical physics experiments and radiation dose measurement, the three-dimensional water tank is a key device, mainly used to measure the dose distribution characteristics of radiation (such as X-rays, gamma rays, electron beams, etc.) in water phantoms.

[0003] To ensure the detector can achieve three-dimensional motion within the tank while preventing the drive device (motor) from being immersed in water, traditional three-dimensional water tanks typically use a screw assembly combined with a synchronous belt or chain. For example, the patent "CN109116406A A Radiation Detection Device" discloses a technical solution that allows the detector to move in all directions within a three-dimensional water tank. However, during rapid motion, this technical solution is prone to vibration and elastic deformation due to the inherent characteristics of the belt (chain), which in turn causes positioning errors in the detector and makes it difficult to meet high-precision calibration requirements. On the other hand, transmission components (such as gears) are often alternately exposed to water and air, which is prone to rust and other phenomena, thereby affecting the accuracy of movement. Finally, current three-dimensional water tanks are also equipped with a leveling mechanism. For example, the patent "CN109557950A A Three-Dimensional Water Tank Horizontal Surface Automatic Leveling Device and Method" discloses a leveling technical solution. However, this technical solution has a low fault tolerance rate. If a leveling motor fails, the entire experimental process will be immediately interrupted, thus failing to provide a strong guarantee for the long-term stable operation of the equipment. Summary of the Invention

[0004] The object of the present invention is to provide a three-dimensional water tank with a three-coordinate adjustment system to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a three-dimensional water tank with a three-coordinate adjustment system, the three-dimensional water tank including a trolley, a transparent water tank, a three-coordinate adjustment system and a detector, a lifting column is provided at the middle position of the trolley, a leveling mechanism is provided above the lifting column, the transparent water tank is provided on the leveling mechanism, the three-coordinate adjustment system and the detector are both provided in the transparent water tank, the transparent water tank is made of transparent PMMA material and is used to hold water for detection, the detector is used to sense the intensity of radiation and complete data collection, when the present invention is working, the height of the transparent water tank is adjusted by the lifting column to adapt to different radiation simulation devices, the levelness of the transparent water tank is adjusted by the leveling mechanism to ensure the accuracy of the experimental data, and the three-coordinate adjustment system allows the detector to move in the transparent water tank in the vertical, horizontal and diagonal directions, thereby measuring PDD (percent depth dose), Profile (off-axis ratio curve) and other data.

[0006] Furthermore, the trolley is also provided with a water tank and a water pump, one end of the water pump is connected to the water tank, and the other end of the water pump is connected to the transparent water tank. The purpose of quickly pumping and releasing water is achieved through the water pump and the water tank. The handle end of the trolley is provided with a touch screen control panel, and the operation of the three-coordinate adjustment system is controlled by the touch screen control panel to drive the detector to perform three-dimensional movement in the transparent water tank.

[0007] Furthermore, the three-coordinate adjustment system includes a first drive mechanism, a second drive mechanism, a third drive mechanism, a lifting frame and a mounting frame. The first drive mechanism and the mounting frame are both arranged at the upper side end of the transparent water tank. The mounting frame is provided with a first slide. The second drive mechanism and the third drive mechanism are both arranged on the first slide. The lifting frame is provided at the working end of the second drive mechanism. The lifting frame is provided with a second slide. The detector is provided on the second slide. The second slide is connected to the working end of the third drive mechanism. The second slide is driven to move horizontally in the transparent water tank by the third drive mechanism. The first drive mechanism and the second drive mechanism in the present invention are both screw structures (the functions realized by the first drive mechanism and the second drive mechanism belong to conventional technical means in this field, and the specific structure is not described). The first drive mechanism drives the first slide and the second drive mechanism and the third drive mechanism to move along the side of the transparent water tank, and the second drive mechanism drives the lifting frame to perform lifting and lowering movements in the transparent water tank.

[0008] Furthermore, the third driving mechanism includes a third motor, a spline shaft, a horizontal lead screw and a transmission seat, the working shaft of the third motor is connected to the spline shaft, the working end of the horizontal lead screw is connected to the second slide seat, the transmission seat is arranged on the spline shaft and is fixedly connected to the lifting frame, a cavity is arranged inside the transmission seat, a first bevel gear and a second bevel gear are arranged in the cavity, the first bevel gear is arranged on the spline shaft, the second bevel gear is arranged on the horizontal lead screw, the first bevel gear is meshed with the second bevel gear, and the inner wall of the first bevel gear in the present invention is provided with key teeth so that the first bevel gear is engaged with the spline While the shaft rotates synchronously, it can also move axially along the spline shaft. When the staff needs to drive the second slide on the lifting frame to move horizontally, they only need to turn on the third motor. The third motor can drive the first bevel gear to rotate, and then the second bevel gear and the horizontal screw are rotated, and the second slide on the lifting frame is driven to move horizontally through the horizontal screw. Compared with the current method of controlling the horizontal movement of the detector in the transparent water tank through synchronous belts, the present invention controls the horizontal movement of the detector in the transparent water tank through the horizontal screw. On the one hand, the positioning accuracy is higher, and on the other hand, the speed stability is stronger, which avoids vibration and other phenomena when the belt moves too fast.

[0009] Furthermore, a group of sealing sleeves are provided at both upper and lower ends of the cavity, and a group of end covers are provided at the ends of the two groups of sealing sleeves away from each other.

[0011] When assembling the third drive mechanism of the present invention, compressed air can be filled into the cavity to make the environment in the cavity in a positive pressure state. When the sealing of the cavity is not destroyed, under the action of air pressure, the sensing block in the sensing groove is close to the mounting groove, and the compression spring on the spring rod is in a stretched state. When the sealing of the cavity is destroyed (such as gas leakage due to wear, looseness or external impact), the air pressure in the cavity decreases. Under the action of the rebound force of the compression spring, the sensing rack and the sensing block will move toward the direction of the cavity. Since the sensing rack is meshed with the sensing gear, the sensing gear and the pointer dial will rotate synchronously. The staff can judge whether the sealing of the cavity is destroyed by observing the position change of the pointer dial. Through the above technical solution, the present invention realizes intelligent and visual monitoring of the internal sealing of the transmission seat, improves the reliability and maintenance efficiency of the equipment, and reduces the risk of the detection water in the transparent water tank entering and being retained inside the transmission seat, thereby ensuring that the transmission components in the transmission seat can operate stably for a long time.

[0012] Furthermore, the leveling mechanism includes a horizontal adjustment seat and an adjustment plate, the horizontal adjustment seat is arranged on the adjustment plate and is provided with an inclination sensor inside, and the horizontality of the transparent water tank is monitored by the inclination sensor, the adjustment plate is connected to the lifting column, and a first leveling seat, a second leveling seat and a third leveling seat are provided on the adjustment plate, a first installation box is provided below the first leveling seat, and a first adjustment component is provided in the first installation box, a second installation box is provided below the second leveling seat, and a second adjustment component is provided in the second installation box, the third leveling seat in the present invention is fixedly mounted on the adjustment plate, and the first leveling seat and the second leveling seat are movably mounted on the adjustment plate, the first leveling seat is driven to rise and fall by the first adjustment component, and the second leveling seat is driven to rise and fall by the second adjustment component, and the purpose of adjusting the horizontality of the transparent water tank is achieved through the cooperation of the inclination sensor, the first adjustment component and the second adjustment component.

[0013] Furthermore, the first adjusting component includes a first leveling screw and a first leveling motor, the first leveling seat is arranged at the working end of the first leveling screw, a first driven gear and a first driven pulley are arranged below the first leveling screw, a first electromagnet is fixedly installed on the working shaft of the first leveling motor, a group of first fixing frames are respectively provided on the upper and lower sides of the first electromagnet, the two groups of first fixing frames are fixedly connected by a first bolt and a first nut, a group of first fixing frames close to the first mounting box is fixedly connected to the first mounting box by a first screw, a first driving gear is provided on the outside of a group of first fixing frames close to the first mounting box, and a first driving pulley is provided on the outside of a group of first fixing frames away from the first mounting box, the first driving gear and the first driving pulley are both provided with a magnetic block (not shown in the figure) on one end close to the first electromagnet, and the magnetic poles of the magnetic block on the first driving gear and the magnetic block on the first driving pulley are the same at the ends close to each other.

[0014] Furthermore, the second adjusting assembly includes a second leveling screw and a second leveling motor, the second leveling seat is arranged at the working end of the second leveling screw, a second driven gear and a second driven pulley are arranged below the second leveling screw, a second electromagnet is fixedly installed on the working shaft of the second leveling motor, a group of second fixing frames are respectively provided on the upper and lower sides of the second electromagnet, the two groups of second fixing frames are fixedly connected by second bolts and second nuts, a group of second fixing frames close to the second mounting box is fixedly connected to the second mounting box by second screws, a second driving gear is provided on the outside of a group of second fixing frames close to the second mounting box, and a second driving pulley is provided on the outside of a group of second fixing frames away from the second mounting box, the second driving gear and the second driving pulley are both provided with magnetic blocks (not shown in the figure) on the ends close to the second electromagnet, and the magnetic poles of the magnetic blocks on the second driving gear and the second driving pulley are close to each other.

[0015] Furthermore, before the present invention works, the staff can first turn on the first electromagnet and the second electromagnet, and generate a set of magnetic fields that attract the first driving gear through the first electromagnet, and generate a set of magnetic fields that attract the second driving gear through the second electromagnet. At this time, the staff turns on the first leveling motor, and the first electromagnet and the first driving gear rotate synchronously (the first driving pulley is stationary), and turns on the second leveling motor, and the second electromagnet and the second driving gear rotate synchronously (the second driving pulley is stationary). In the present invention, the first driving gear is meshed with the first driven gear, and the second driving gear is meshed with the second driven gear. Under the action of the first driving gear and the first driven gear, the present invention can drive the first leveling screw to rotate through the first leveling motor, thereby driving the first leveling seat to rise and fall. Under the action of the second driving gear and the second driven gear, the second leveling motor can drive the second leveling screw to rotate, thereby driving the second leveling seat to rise and fall. The leveling effect is detected in real time by the inclination sensor. When the leveling is completed, the staff can turn on the three-coordinate adjustment system, and the three-coordinate adjustment system drives the detector to achieve three-dimensional movement in the transparent water tank to measure data such as PDD (percent depth dose) and Profile (off-axis ratio curve).

[0016] Furthermore, the first driving pulley and the second driven pulley are connected via a first transmission belt, and the second driving pulley and the first driven pulley are connected via a second transmission belt.

[0017] During operation of the present invention, if it is found that the first leveling motor fails to rotate or there is a problem with the rotation accuracy, the staff can first turn on the second electromagnet to generate a set of magnetic fields that attract the second driving gear through the second electromagnet, and then turn on the second leveling motor to make the second electromagnet and the second driving gear rotate synchronously (the second driving pulley does not move). Under the action of the second driving gear and the second driven gear, the second leveling motor drives the second leveling screw to rotate, and then drives the second leveling seat to rise and fall, so that the second leveling seat and the third leveling seat are in the same horizontal plane. Then, the staff changes the direction of the magnetic field of the second electromagnet, generates a set of magnetic fields that attract the second driving pulley through the second electromagnet, and then turns on the second leveling motor again to make the second electromagnet and the second driving pulley rotate synchronously (the second driving gear does not move). Under the action of the driving pulley, the first driven pulley and the second transmission belt, the first leveling screw is driven to rotate by the second leveling motor, and then the first leveling seat is controlled to be raised and lowered, so that the first leveling seat, the second leveling seat and the third leveling seat are in the same horizontal plane, thereby achieving the purpose of leveling. Similarly, when it is found that the second leveling motor fails and cannot rotate or there is a problem with the rotation accuracy, the staff can change the direction of the magnetic field generated by the first electromagnet. When the first electromagnet attracts the first driving gear, the first leveling motor controls the lifting and lowering of the first leveling seat. When the first electromagnet attracts the first driving pulley, the first leveling motor controls the lifting and lowering of the second leveling seat. Through the above technical solution, the present invention greatly improves the reliability and fault tolerance of the equipment. When any leveling motor fails, the present invention can ensure the continuous operation of the leveling mechanism by switching the magnetic field direction of the electromagnet.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Compared with the current three-dimensional water tank, the present invention is equipped with a three-coordinate adjustment system. Through the three-coordinate adjustment system, the detector can move in the vertical, horizontal and diagonal directions in the transparent water tank, thereby measuring data such as PDD (percent depth dose) and Profile (off-axis ratio curve). Compared with the current method of controlling the horizontal movement of the detector in the transparent water tank by means of a synchronous belt, the present invention adopts a horizontal screw combined with a spline shaft and a bevel gear meshing transmission, which significantly improves the movement accuracy and stability of the detector in the transparent water tank and avoids positioning deviation caused by belt vibration or elastic deformation.

[0020] 2. The present invention further provides a detection assembly within the transmission seat to monitor changes in the air pressure in the cavity within the transmission seat in real time, ensuring that the transmission components within the transmission seat operate for a long time in an environment free of water infiltration. When the cavity sealing is damaged due to wear, looseness, or external impact, the sensing block and the sensing rack will move under the action of the air pressure change and the spring rebound force, thereby driving the sensing gear and the pointer dial to rotate. The staff can intuitively judge whether the sealing is damaged from the change in the position of the pointer dial, thereby realizing intelligent and visual monitoring of the sealing inside the transmission seat, reducing the risk of test water in the transparent water tank entering and being retained inside the transmission seat, and avoiding rust, corrosion, and other failures of the transmission components caused by the ingress of test water, thereby ensuring the long-term stable operation of the transmission components within the transmission seat and reducing the occurrence of equipment failures.

[0021] 3. The leveling mechanism of the present invention realizes redundant control under fault conditions through the dual-mode switching design of electromagnets, gears and pulleys, greatly improves the fault tolerance of the equipment, and solves the problem of the traditional leveling mechanism causing the entire experiment to be interrupted due to the failure of a certain leveling motor. When the first leveling motor or the second leveling motor fails and cannot rotate or has problems with the rotation accuracy, the present invention can change the power transmission path by switching the magnetic field direction of the first electromagnet and the second electromagnet, and realize the control of the lifting and lowering of the two leveling seats by one leveling motor, thereby ensuring the continuous operation of the leveling mechanism and providing a strong guarantee for the long-term stable operation of the equipment.

[0036] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0037] Example: Figures 1-13As shown, the present invention provides a technical solution, a three-dimensional water tank with a three-coordinate adjustment system, the three-dimensional water tank includes a trolley 1, a transparent water tank 3, a three-coordinate adjustment system 4 and a detector 7. A lifting column is provided at the middle position of the trolley 1, and a leveling mechanism is provided above the lifting column. The transparent water tank 3 is provided on the leveling mechanism, and the three-coordinate adjustment system 4 and the detector 7 are both provided in the transparent water tank 3. The transparent water tank 3 is made of transparent PMMA material and is used to hold water for detection. The detector 7 is used to sense the intensity of the radiation and complete data collection. When the present invention is working, the height of the transparent water tank 3 is adjusted by the lifting column to adapt to different radiation simulation devices, and the levelness of the transparent water tank 3 is adjusted by the leveling mechanism to ensure the accuracy of the experimental data. The three-coordinate adjustment system 4 allows the detector 7 to move in the transparent water tank 3 in the vertical, horizontal and diagonal directions, thereby measuring data such as PDD (percent depth dose) and Profile (off-axis ratio curve).

[0038] like Figure 1-Figure 3 As shown, the trolley 1 is also provided with a water tank 2 and a water pump. One end of the water pump is connected to the water tank 2, and the other end of the water pump is connected to the transparent water tank 3. The purpose of quickly pumping and releasing water is achieved through the water pump and the water tank 2. A touch screen control panel is provided at the handle end of the trolley 1. The touch screen control panel controls the operation of the three-coordinate adjustment system 4 to drive the detector 7 to perform three-dimensional movement in the transparent water tank 3.

[0039] like Figure 2 、 Figure 4 As shown, the three-coordinate adjustment system 4 includes a first driving mechanism 41, a second driving mechanism 42, a third driving mechanism 43, a lifting frame 44 and a mounting frame 45. The first driving mechanism 41 and the mounting frame 45 are both arranged at the upper side of the transparent water tank 3. A first slide is arranged on the mounting frame 45. The second driving mechanism 42 and the third driving mechanism 43 are both arranged on the first slide. The lifting frame 44 is arranged at the working end of the second driving mechanism 42. A second slide is arranged on the lifting frame 44. The detector 7 is arranged on the second slide. The working ends of the second slide and the third driving mechanism 43 are arranged. The two ends are connected, and the second slide is driven by the third driving mechanism 43 to move horizontally in the transparent water tank 3. The first driving mechanism 41 and the second driving mechanism 42 in the present invention are both screw structures (the functions realized by the first driving mechanism 41 and the second driving mechanism 42 belong to conventional technical means in this field, and the specific structure is not described). The first driving mechanism 41 drives the first slide and the second driving mechanism 42 and the third driving mechanism 43 to move along the side of the transparent water tank 3, and the second driving mechanism 42 drives the lifting frame 44 to perform lifting movements in the transparent water tank 3.

[0040] like Figure 2 、 Figure 4-Figure 7As shown, the third driving mechanism 43 includes a third motor 431, a spline shaft 432, a horizontal screw 433 and a transmission seat 434. The working shaft of the third motor 431 is connected to the spline shaft 432, the working end of the horizontal screw 433 is connected to the second slide, the transmission seat 434 is arranged on the spline shaft 432 and is fixedly connected to the lifting frame 44, and a cavity is provided inside the transmission seat 434, and a first bevel gear and a second bevel gear are provided in the cavity. The first bevel gear is provided on the spline shaft 432, and the second bevel gear is provided on the horizontal screw 433. The first bevel gear is meshed with the second bevel gear.

[0041] The first bevel gear in the present invention is provided with key teeth on the inner wall, so that the first bevel gear can rotate synchronously with the spline shaft 432 and can also move axially along the spline shaft 432. When the staff needs to drive the second slide on the lifting frame 44 to move horizontally, they only need to turn on the third motor 431. The third motor 431 can drive the first bevel gear to rotate, and then the second bevel gear and the horizontal screw 433 can rotate, and the second slide on the lifting frame 44 is driven to move horizontally through the horizontal screw 433. Compared with the current control of the horizontal movement of the detector 7 in the transparent water tank 3 by synchronous belts and the like, the present invention controls the horizontal movement of the detector 7 in the transparent water tank 3 by the horizontal screw 433. On the one hand, the positioning accuracy is higher, and on the other hand, the speed stability is stronger, thereby avoiding vibration and the like when the belt moves too fast.

[0042] like Figure 5-Figure 7 As shown, a set of sealing sleeves 4341 are provided at the upper and lower ends of the cavity, and a set of end covers 4342 are provided at the ends away from each other of the two sets of sealing sleeves 4341. A detection component is provided at the side end of the cavity to detect the sealing of the cavity.

[0043] like Figure 5-Figure 7 As shown, the detection component includes a mounting slot 4343 and a sensing slot 4346. The sensing slot 4346 is communicated with the cavity. A sensing block is arranged in the sensing slot 4346. A sensing gear 4344 and a sensing rack 4347 are arranged in the mounting slot 4343. The sensing rack 4347 is movably installed in the mounting slot 4343 through a spring rod. The sensing gear 4344 is engaged with the sensing rack 4347. One end of the sensing rack 4347 is connected to the sensing block. A display slot is arranged above the mounting slot 4343. A pointer dial 4345 is arranged in the display slot. The pointer dial 4345 is connected to the sensing gear 4344 through a rotating shaft. A glass piece is arranged above the display slot.

[0044] When assembling the third driving mechanism 43 of the present invention, compressed air can be filled into the cavity to make the environment in the cavity in a positive pressure state. When the sealing of the cavity is not damaged, under the action of air pressure, the sensing block in the sensing groove 4346 is close to the mounting groove 4343, and the compression spring on the spring rod is in a stretched state. When the sealing of the cavity is damaged (such as due to wear, looseness or external impact causing gas leakage), the air pressure in the cavity decreases. Under the action of the rebound force of the compression spring, the sensing rack 4347 and the sensing block will move toward the direction of the cavity. 347 is engaged with the sensing gear 4344, so the sensing gear 4344 and the pointer disk 4345 will rotate synchronously. The staff can judge whether the sealing of the cavity is destroyed by observing the position change of the pointer disk 4345. Through the above technical solution, the present invention realizes the intelligent and visual monitoring of the internal sealing of the transmission seat 434, improves the reliability and maintenance efficiency of the equipment, and reduces the risk of the test water in the transparent water tank 3 entering the transmission seat 434 and being retained, thereby ensuring that the transmission components in the transmission seat 434 can operate stably for a long time.

The magnetic poles of the magnetic blocks on the second driving gear 6531 and the magnetic blocks on the second driving pulley 6532 at their ends close to each other are the same.

[0048] Before the present invention works, the staff can first turn on the first electromagnet 6421 and the second electromagnet 6521, and generate a set of magnetic fields that attract the first driving gear 6431 through the first electromagnet 6421, and generate a set of magnetic fields that attract the second driving gear 6531 through the second electromagnet 6521. At this time, the staff turns on the first leveling motor 642, and the first electromagnet 6421 and the first driving gear 6431 rotate synchronously (the first driving pulley 6432 does not move), and turns on the second leveling motor 652, and the second electromagnet 6521 and the second driving gear 6531 rotate synchronously (the second driving pulley 6532 does not move). In the present invention, the first driving gear 6431 is meshed with the first driven gear, and the second driving gear 6531 is meshed with the second driven gear. The second driven gear is engaged. Under the action of the first driving gear 6431 and the first driven gear, the present invention can drive the first leveling screw 641 to rotate through the first leveling motor 642, thereby driving the first leveling seat 61 to rise and fall. Under the action of the second driving gear 6531 and the second driven gear, the second leveling screw 651 can be driven to rotate through the second leveling motor 652, thereby driving the second leveling seat 62 to rise and fall. The leveling effect is detected in real time by the inclination sensor. When the leveling is completed, the staff can start the three-coordinate adjustment system 4, and drive the detector 7 to realize three-dimensional movement in the transparent water tank 3 through the three-coordinate adjustment system 4 to measure data such as PDD (percent depth dose) and Profile (off-axis ratio curve).

[0049] like Figures 8-13 As shown, the first driving pulley 6432 is connected to the second driven pulley via a first transmission belt, and the second driving pulley 6532 is connected to the first driven pulley via a second transmission belt.

[0050] During the operation of the present invention, if it is found that the first leveling motor 642 fails to rotate or has problems with the rotation accuracy, the staff can first turn on the second electromagnet 6521, and generate a set of magnetic fields that attract the second driving gear 6531 through the second electromagnet 6521, and then turn on the second leveling motor 652, so that the second electromagnet 6521 and the second driving gear 6531 rotate synchronously (the second driving pulley 6532 does not move). Under the action of the second driving gear 6531 and the second driven gear, the second leveling motor 652 drives the second leveling screw 651 to rotate, and then drives the second leveling seat 62 to rise and fall, so that the second leveling seat 62 and the third leveling seat 63 are in the same horizontal plane. Then, the staff changes the direction of the magnetic field when turning on the second electromagnet 6521, and generates a set of magnetic fields that attract the second driving pulley 6532 through the second electromagnet 6521, and then turns on the second leveling motor 652 again, so that the second electromagnet 6521 and the second driving pulley 6532 rotate synchronously (the second driving gear 6531 is stationary), and under the action of the second active pulley 6532, the first driven pulley and the second transmission belt, the first leveling screw 641 is driven to rotate by the second leveling motor 652, thereby controlling the lifting and lowering of the first leveling seat 61, so that the first leveling seat 61, the second leveling seat 62 and the third leveling seat 63 are in the same horizontal plane, thereby achieving the purpose of leveling. Similarly, when it is found that the second leveling motor 652 fails and cannot rotate or there is a problem with the rotation accuracy, the staff can change the direction of the magnetic field generated by the first electromagnet 6421. When the first electromagnet 6421 attracts the first driving gear 6431, the first leveling motor 642 controls the lifting and lowering of the first leveling seat 61. When the first electromagnet 6421 attracts the first active pulley 6432, the first leveling motor 642 controls the lifting and lowering of the second leveling seat 62. Through the above technical solution, the present invention greatly improves the reliability and fault tolerance of the equipment. When any leveling motor fails, the present invention can ensure the continuous operation of the leveling mechanism by switching the magnetic field direction of the electromagnet.

[0051] The working principle of the present invention is as follows: when working, the test water in the water storage tank 2 is transported to the transparent water tank 3 through the water pump, and the height of the transparent water tank 3 is adjusted by the lifting column. By turning on the first electromagnet 6421 and the second electromagnet 6521, the first driving gear 6431 is fixed to the first electromagnet 6421, and the second driving gear 6531 is fixed to the second electromagnet 6521. Then, the first leveling motor 642 and the second leveling motor 652 are turned on. The first leveling motor 642 can drive the first leveling screw 641 to rotate, thereby driving the first leveling seat 61 to rise and fall. The second leveling motor 652 can drive the second leveling screw 651 to rotate, thereby driving the second leveling seat 62 to rise and fall. The leveling effect is detected in real time by the inclination sensor. When the leveling is completed, the staff can turn on the The three-coordinate adjustment system 4 drives the detector 7 to realize three-dimensional movement in the transparent water tank 3 to measure data such as PDD (percent depth dose) and Profile (off-axis ratio curve). During the operation of the present invention, if the sealing of the cavity in the transmission seat 434 is destroyed, the air pressure in the cavity will decrease. Under the action of the compression spring rebound force, the sensing rack 4347 and the sensing block will move toward the direction of the cavity, and the sensing gear 4344 and the pointer disk 4345 will rotate synchronously. The staff can judge whether the sealing of the cavity is destroyed by observing the position change of the pointer disk 4345, and then replace the sealing sleeves 4341 set at the upper and lower ends of the cavity in time after the work is completed to avoid the detection water from being retained in the cavity and affecting the stable operation of the transmission components in the cavity.
