Abstract

This invention relates to a device and method for adjusting the sealing and levelness of purification components. By incorporating a main frame module, a composite lamp assembly levelness detection module, and a pressure-sensing sealing detection module, the installation dimensions, clamping degree, and levelness of the support frame can be simultaneously checked and adjusted. The invention uses pressure sensors located on the upper cover to transmit the clamping degree in real-time as electrical signals to a signal conditioning and display module. Based on the pressure data fed back by each sensor, the height of the support frame can be adjusted overall or locally to ensure that the clamping pressure at the four corners of the support frame reaches the specified value. Simultaneously, the invention adjusts the levelness of the support frame through a composite lamp assembly levelness detection module installed at the center of the upper cover to meet the levelness requirements. This invention greatly improves the standardization, scientific rigor, and normalization of the adjustment work of the purification component support frame, significantly reducing unsafe operating conditions that may be caused by human factors.

Description

Technical Field

[0001] This invention belongs to the field of nuclear air purification technology, and relates to a device and method for adjusting the sealing and levelness of purification components. Background Technology

[0002] When installing purification components in a small ventilation and purification system, it is necessary to manually adjust the supporting frame of the purification components to avoid dimensional deviations caused by gravity during long-term use.

[0003] Currently, only basic auxiliary measurement methods (measuring tape, steel ruler, etc.) are used to adjust and confirm the installation dimensions of the support frame of the purification components. Due to the lack of dedicated equipment for quantitative evaluation of the installation effect, the adjustment effect of the support frame is easily affected by the experience level of the adjustment engineer and other subjective factors, leading to unstable adjustment results. This can result in problems such as insufficiently tight installation of the purification components or uneven stress at the four corners. Furthermore, if the purification components themselves are poorly installed, the airflow intended for filtration may leak mechanically into the downstream airflow instead of passing through the purification components, resulting in low filtration efficiency and failure to meet acceptance criteria. In severe cases, this can even trigger probe alarms.

[0004] Practical applications show that the adjustment effect of the load-bearing frame of the purification component has become a key factor affecting the purification effect of the purification component. Summary of the Invention

[0005] In view of the deficiencies in the existing technology, the purpose of this invention is to provide a device and method for adjusting the sealing and levelness of the purification component installation, which can realize the simultaneous inspection and adjustment of the tightness and levelness of the bearing frame, and provide a scientific and quantitative evaluation means for the inspection and adjustment of the frame.

[0006] To achieve this objective, the present invention provides a device for adjusting the sealing and levelness of a purification component during installation, the device comprising:

[0007] The main frame module is rectangular in shape and includes an upper cover plate and a lower support base. The upper cover plate and the lower support base are connected by four sets of linkage assemblies. Each linkage assembly includes an upper fixed base, an upper rotating link, a lower rotating link, and a lower fixed base that are rotatably connected in sequence. The upper fixed base of each linkage assembly is fixedly installed at a right angle on the lower surface of the upper cover plate, and the lower fixed base is correspondingly fixedly installed at a right angle on the upper surface of the lower support base. A through hole is reserved at the center of the upper cover plate.

[0008] The composite lamp assembly levelness detection module includes a movable spotlight module and a fixed laser module. The fixed laser module is detachably mounted at the center of the upper cover plate through the through hole; the movable spotlight module is detachably mounted at the center of the fixed laser module.

[0009] The pressure sensing and sealing detection module includes a pressure sensor and a signal conditioning and display module, which are connected by a transmission wire; the pressure sensor is disposed on the upper cover plate, and the signal conditioning and display module is installed below the upper cover plate.

[0010] Furthermore, the device includes a pressure-bearing state and a pressure-relieving state.

[0011] Furthermore, the fixed laser module includes an annular fixed base and laser lights, with the laser lights evenly arranged and installed in the annular fixed base;

[0012] The annular fixed base is detachably mounted at the center of the upper cover plate through the through hole, and the movable spotlight module is detachably mounted at the center of the annular fixed base.

[0013] Furthermore, the movable spotlight module includes a horizontal gyroscope and a follow-up spotlight;

[0014] The horizontal gyroscope is mounted on the inner circumference of the annular fixed base, and the follow-up spotlight is mounted at the center of the horizontal gyroscope.

[0015] Furthermore, the number of laser lights is 4 + 2n, where n is a natural number.

[0016] Furthermore, the method for judging and adjusting the levelness of the supporting frame through the composite lamp group levelness detection module to meet the levelness requirements is as follows: the second angle formed by the central axis of the laser lamp and the central axis of the follow-up spotlight should maintain a certain angle;

[0017] The method for determining whether the second included angle is properly adjusted is as follows: take the leftmost end of the follow-up spotlight lens as the starting point, take the leftmost end of the light spot projected below the follow-up spotlight as the ending point, and record the angle between the line connecting the starting point and the ending point and the central axis of the follow-up spotlight as the first included angle; adjust the angle of the laser light so that the second included angle is equal to the first included angle.

[0018] Furthermore, there are four sets of pressure sensors, which are respectively located at the four right-angle vertices of the upper cover plate.

[0019] The present invention also provides a method for adjusting the sealing and levelness of a purification component during installation. The method is implemented using the device for adjusting the sealing and levelness of the purification component during installation, and includes the following steps:

[0020] S1. Adjust the load-bearing frame to an uncompressed state;

[0021] S2. Calibrate the four pressure sensors: Use calibration weights to perform a functional check on the four pressure sensors to ensure that the detection error of the four pressure sensors is ≤ ±2%.

[0022] S3. Place the device into the support frame, ensuring that the support frame is correctly aligned with the bottom corners of the device;

[0023] S4. Adjust the bearing frame to the compressed state, adjust the device to the pressure-bearing state, and control the height of the four corners of the bearing frame by adjusting the height of the bolts at the bottom of the bearing frame until the pressure values ​​of the four pressure sensors are displayed in the signal conditioning and display module.

[0024] Then, continue to adjust according to the required tightness, so that the pressure values ​​of the four pressure sensors displayed in the signal conditioning and display module are all within the range of 10kg-50kg, and the error between the pressure value of each pressure sensor and the expected pressure value is less than ±5%.

[0025] At the same time, it was checked and confirmed that the halo and spot of light projected by the movable spotlight module and the fixed laser module onto the bottom of the supporting frame did not show any obvious deviation or overlap.

[0026] S5. Change the device from a pressure-bearing state to a stress-relieving state, and remove the device to complete the adjustment of the load-bearing frame.

[0027] Furthermore, step S4 also includes the following specific steps:

[0028] Record four sets of pressure values ​​in the signal conditioning and display module;

[0029] The relative positions of the halo and spot of light projected by the movable spotlight module and the fixed laser module onto the bottom of the supporting frame are recorded by taking photos.

[0030] The beneficial effects of this invention are that, by employing the device and method for adjusting the sealing and levelness of the purification components provided by this invention, the compaction and levelness of the supporting frame can be simultaneously checked and adjusted through the main frame module, the composite lamp group levelness detection module, and the pressure-sensing sealing detection module. This invention transmits the compaction level in real-time as an electrical signal to the signal conditioning and display module via pressure sensors arranged on the upper cover plate. The signal conditioning and display module processes the received electrical signals and converts them into corresponding pressure value data. Workers can adjust the height of the supporting frame, either overall or locally, based on the pressure value data fed back by each sensor to ensure that the compaction pressure at the four corners of the supporting frame reaches the specified value, and that the difference in compaction pressure is within a specified range. Simultaneously, this invention installs a composite lamp group levelness detection module at the center of the upper cover plate. A movable spotlight module indicates the required levelness of the supporting frame, while a fixed laser module indicates the current levelness. Workers can adjust the position of the two sets of lights according to their relationship, ensuring that the spotlight illumination range is within the laser light ring to meet the levelness requirements. This invention enables the inspection and adjustment of the installation dimensions, clamping degree, and levelness of the load-bearing frame. The related display values ​​and visual status provide a scientific and quantitative evaluation method for the adjustment effect of the load-bearing frame, which greatly improves the standardization, scientification, and normalization of the load-bearing frame adjustment work and significantly reduces unsafe operating conditions that may be caused by human factors.

Detailed Implementation

[0042] The technical solution of the present invention will be further clearly and completely described below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] like Figures 1-10 As shown in the figure, this embodiment provides a device for adjusting the sealing and levelness of a purification component. The device mainly includes: a main frame module, a composite lamp group levelness detection module, and a pressure-sensing sealing detection module.

[0044] The main frame module includes an upper cover plate 100 and a lower support base 200. The upper cover plate 100 and the lower support base 200 are connected by four sets of connecting rod assemblies. Each set of connecting rod assemblies includes an upper fixed base 310, an upper rotating connecting rod 320, a lower rotating connecting rod 330, and a lower fixed base 340 that are rotatably connected in sequence. The upper fixed base 310 is fixedly connected to the upper cover plate 100, and the lower fixed base 340 is fixedly connected to the lower support base 200.

[0045] Specifically, such as Figure 1As shown, the main frame module is a cuboid, and the upper cover plate 100 and the lower support base 200 are both rectangular; the upper fixed base 310 of each linkage assembly is fixedly installed at a right angle on the lower surface of the upper cover plate 100, and the lower fixed base 340 is fixedly installed at a right angle on the upper surface of the lower support base 200. The orthographic projections of the upper fixed base 310 and the lower fixed base 340 of each linkage assembly on the lower support base 200 coincide.

[0046] By rotating the upper rotating connecting rod 320 and the lower rotating connecting rod 330, the device can be adjusted to the following position. Figure 5 The pressure condition shown or as Figure 6 The unloading state is shown.

[0047] A through hole is pre-drilled at the center of the upper cover plate 100, through which the composite lamp assembly level detection module is detachably installed at the center of the upper cover plate 100. Specifically, the composite lamp assembly level detection module includes a movable spotlight module 510 and a fixed laser module 520. The fixed laser module 520 is detachably installed at the center of the upper cover plate 100 through the through hole; the movable spotlight module 510 is detachably installed at the center of the fixed laser module 520. The movable spotlight module 510 indicates the required level of the supporting frame, and the fixed laser module 520 indicates the current level of the supporting frame. Workers can adjust the position of the two sets of lights (the spotlight light from the movable spotlight module 510 and the laser light from the fixed laser module 520) to ensure that the spotlight illumination range is within the laser light ring, thus meeting the level requirements.

[0048] The fixed laser module 520 includes an annular fixed base 521 and laser lights 522, with the laser lights 522 evenly arranged and installed in the annular fixed base 521. The annular fixed base 521 is detachably installed at the center of the upper cover plate 100 through the through hole, and the movable spotlight module 510 is detachably installed at the center of the annular fixed base 521. Specifically, the movable spotlight module 510 includes a horizontal gyroscope 511 and a follower spotlight 512, and the movable spotlight module 510 can be completely disassembled and assembled; the horizontal gyroscope 511 is installed on the inner circumference of the annular fixed base 521, and the follower spotlight 512 is installed at the center of the horizontal gyroscope 511.

[0049] Optionally, the number of laser lights 522 is 4 + 2n, where n is a natural number, taking values ​​of 0, 1, 2, 3, ...

[0050] Optional, such as Figure 7 , Figure 8As shown, the method for judging and adjusting the level of the supporting frame by the composite lamp group level detection module located at the center of the upper cover plate to meet the level requirements is as follows: the second included angle (angle 2) formed by the central axis of the laser lamp 522 and the central axis of the follow-up spotlight 512 should maintain a certain angle; the method for judging whether the size of the second included angle (angle 2) is adjusted appropriately is as follows: take the leftmost end of the lens of the follow-up spotlight 512 as the starting point, take the leftmost end of the light spot projected below the follow-up spotlight 512 as the ending point, and record the angle between the line connecting the starting point and the ending point and the central axis of the follow-up spotlight 512 as the first included angle (angle 1); adjust the angle of the laser lamp 522 so that the second included angle (angle 2) is equal to the first included angle (angle 1); in this state, it can be guaranteed that at any height, as long as the whole device is in a horizontal state, the light spots projected by the laser lamp 522 and the follow-up spotlight 512 of the composite lamp group level detection module will not overlap, and always have effective indication capability.

[0051] The pressure sensing and sealing detection module includes a pressure sensor 600 and a signal conditioning and display module 400, wherein the pressure sensor 600 and the signal conditioning and display module 400 are connected by a transmission wire. The pressure sensor 600 is disposed on the upper cover plate 100, and the signal conditioning and display module 400 is installed below the upper cover plate 100.

[0052] Specifically, four sets of pressure sensors 600 are respectively installed at the four right-angle vertices of the upper cover plate 100. The four sets of pressure sensors 600 on the upper cover plate 100 transmit the degree of compaction in the form of electrical signals to the signal conditioning and display module 400 in real time. The signal conditioning and display module 400 processes the received electrical signals and converts them into corresponding pressure value data. The operator can make overall or partial adjustments to the height of the support frame based on the pressure value data fed back by each pressure sensor 600 to ensure that the compaction pressure at the four corners reaches the specified value and that the difference in compaction pressure is within the specified range.

[0053] like Figure 9 As shown, in a specific embodiment, the device is used to adjust the support frame of a Type II iodine adsorber and a high-efficiency filter (a cuboid with dimensions of 500mm long * 500mm wide * 292mm high) in a nuclear power plant ventilation system. In the ventilation and purification system, the support frame of the purification components is mainly in two states: uncompressed state C1 and compressed state C2. When the support frame is in the uncompressed state C1, the cam clamping mechanism handle of the support frame is in a horizontal position, and the support frame is at the bottom. In this state, the Type II iodine adsorber and high-efficiency filter are disassembled and assembled. When the support frame is in the compressed state C2, the cam clamping mechanism handle of the support frame is in a vertical position and positioned in the limiting groove. Simultaneously, the support frame is raised to a certain height. In this state, the Type II iodine adsorber and high-efficiency filter are limited and clamped.

[0054] like Figure 10 As shown, this embodiment also provides a method for adjusting the sealing and levelness of the purification component during installation. The method is implemented using the aforementioned device for adjusting the sealing and levelness of the purification component during installation, and mainly includes the following steps:

[0055] S1. Adjust the load-bearing frame to an uncompressed state C1;

[0056] Before adjusting the support frame, prepare the device (a cuboid with dimensions of 500mm long * 500mm wide * 292mm high) that matches the specifications of the support frame of the purification component to be adjusted (i.e., the Type II iodine adsorber and the high-efficiency filter).

[0057] S2. Calibrate the four pressure sensors 600: Use a 1kg calibration weight to perform a functional check on the four pressure sensors 600 to ensure that the detection error of the four pressure sensors 600 is ≤±2%.

[0058] Specifically, step S2 also includes the following steps: turn on the signal conditioning and display module 400 and reset the pressure values ​​of the four pressure sensors 600 displayed in the signal conditioning and display module 400 to zero.

[0059] S3. Place the device into the support frame, ensuring the support frame is correctly aligned with the bottom corners of the device. At this point, the support frame and the device are adjusted together as follows. Figure 9 The C3 state shown in the diagram;

[0060] S4. Adjust the support frame to the compressed state C2. At this time, the device is adjusted to the following position: Figure 5 The pressure-bearing state shown is such that the load-bearing frame, together with the device, is adjusted to... Figure 9 The C4 state shown in the figure; the height of the four corners of the bearing frame is controlled by adjusting the height of the bolts at the bottom of the bearing frame. When the pressure values ​​of the four pressure sensors 600 (feedback data of the four pressure sensors) are displayed in the signal conditioning and display module 400, it indicates that the size of the bearing frame has met the adjustment requirements.

[0061] Then, adjustments are made according to the required tightness, ensuring that the pressure values ​​of the four pressure sensors 600 displayed in the signal conditioning and display module 400 are all within the range of 10kg-50kg, and the error between the pressure value of each pressure sensor 600 and the expected pressure value is less than ±5%. Simultaneously, it is checked and confirmed that the halo and spotlights projected onto the bottom of the frame by the movable spotlight module 510 and the fixed laser module 520 do not show significant deviation or overlap. This indicates that the frame size, tightness, and levelness all meet the technical requirements. The four pressure values ​​in the signal conditioning and display module 400 are recorded, and the relative positions of the halo and spotlights projected onto the bottom of the supporting frame by the movable spotlight module 510 and the fixed laser module 520 are photographed and recorded.

[0062] S5. By simultaneously adjusting the relative positions of the upper rotating link 302 or the lower rotating link 303 in the linkage assembly, the device is changed from a pressure-bearing state to a stress-relieving state. Then, the bearing frame together with the device is adjusted to state C3, and the device is removed. The adjustment of the bearing frame is then complete.

[0063] The above embodiments are merely illustrative examples of the present invention. Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these modifications and variations. The above embodiments or implementation methods are merely illustrative examples of the present invention, and the present invention can also be implemented in other specific ways or other specific forms without departing from the gist or essential characteristics of the present invention. Therefore, the described embodiments should be considered illustrative rather than limiting in any respect. The scope of the present invention should be defined by the appended claims, and any changes equivalent to the intent and scope of the claims should also be included within the scope of the present invention.
