Description

TECHNICAL FIELD

[0001] The application relates to a pressure resistance detection device, in particular to a perfluorocyclohexanone fire extinguisher pressure resistance detection device applied to the field of pressure tests. BACKGROUND

[0002] Fire extinguisher pressure resistance detection is a core process for verifying the structural strength and sealing performance of fire extinguisher containers (such as steel cylinders and aluminum cylinders) in a high-pressure environment. The core goal is to ensure that the fire extinguisher does not leak, deform or explode due to excessive pressure under normal use or extreme conditions. The current mainstream detection method is water pressure detection. However, in the existing fire extinguisher pressure resistance detection device, when the bottle body is directly pressurized during operation, if the bottle body bursts due to high pressure, it may cause fragments to splash or high-pressure impact, seriously threatening the safety of the operator.

[0003] In view of this safety hazard, Chinese invention patent CN108956315B discloses a fire extinguisher bottle pressure test device and test method, which can accurately test whether the fire extinguisher bottle leaks by setting a protective bottle nesting structure and a water pressure test system, and will not cause casualties when the fire extinguisher bottle explodes. However, this patent needs to detect the water pressure strength of the fire extinguisher bottle one by one in application, which has the problems of low efficiency, inability to meet the demand of large-scale detection, and low automation degree. To solve the above efficiency problem, Chinese invention patent CN112834353B discloses a fire extinguisher cylinder full-automatic free body water pressure strength detection equipment, which realizes the automatic operation of fixing and locking, water inlet, water outlet, air inlet and air outlet detection of the dry powder bottle cylinder by setting a water pump, an oil pump and a gas pump cooperating with a ball valve, a positioning tool and a free body clamping device, and is suitable for batch detection, significantly improving the work efficiency.

[0044] It should be noted that the water pump pressurizing mechanism is an existing mechanical mechanism in the water pressure detection device, which is directly quoted here and no changes have been made to its structure and principle. Those skilled in the art can select the water pump pressurizing mechanism according to the actual application requirements, which will not be described here. For example, the water pump pressurizing mechanism includes a driving motor to provide mechanical power, commonly known as an asynchronous motor or a servo motor (supporting speed regulation); a transmission device: connecting the motor and the water pump main shaft, including a shaft coupling, a belt pulley + belt or a gear box, used to match the speed requirements of the motor and the water pump; a water pump: the water pump includes a pump housing that contains internal moving parts and forms a fluid passage, and an impeller that generates centrifugal force by high-speed rotation to push the water flow to increase pressure; a water storage tank for storing water resources; pipelines connecting the water tank, the water pump, the detection water pipe 22 and the control pipe 41, and valve bodies such as overflow valves, throttle valves, pressure relief valves and check valves arranged on the pipelines; a filter can also be provided at the input end of the water pump to filter impurities in the water and prevent the pump body from being clogged or the valve from being damaged. It should be noted that the pipeline connecting the detection water pipe 22 and the control pipe 41 is two independent pipelines, which can be independently controlled by the water pump.

[0045] Figure 3 - Figure 10 The elastic control sleeve 4 is made of elastic material and remains in a contracted state when not under stress. To maintain the durability of the elastic control sleeve 4, multiple elastic recovery members can be fixedly arranged inside the elastic control sleeve 4, and the elastic recovery members are arranged parallel to the radial direction of the elastic control sleeve 4. The elastic control sleeve 4 is fixedly connected to multiple control pipes 41 that are in communication with the pressure control cavity at the lower end of the elastic control sleeve 4. The control pipes 41 extend to the outside of the detection cabinet 2 at the lower end and are in communication with the water pump pressurizing mechanism. The arrangement of the elastic control sleeve 4 and the pressure sensor not only enables the detection of the bottle body deformation data during the pressure test of the bottle body 8, but also effectively detects different diameter ranges of the bottle body 8, thereby expanding the application range of the detection cabinet 1 and enabling intelligent and accurate detection of different specifications of the bottle body 8, improving the economic efficiency of the detection cabinet 1.

[0046] Figure 3 - Figure 10It is shown that after the bottle body 8 is placed in the wrapping shell 3, the intelligent detection processing unit can control the wrapping control unit according to the data transmitted by the parameter setting unit, so that water resources are introduced into the elastic control sleeve 4 through the water pump pressure mechanism and the control pipe 41, so that the elastic control sleeve 4 produces continuous swelling deformation, and drives the lower induction ring 5, the upper induction ring 6 and the side seam induction arc block 7 on it to gradually approach the outer end face of the bottle body 8 until it is tightly attached to the bottle body 8. The pressure sensor in the elastic control sleeve 4 continuously transmits data to the deformation pressure sensing unit, and the intelligent detection processing unit receives the pressure data transmitted by the deformation pressure sensing unit, judges that the tightness of the lower induction ring 5, the upper induction ring 6 and the side seam induction arc block 7 to the bottle body 8 reaches the set requirement, then stops the continuous pressure action of the water pump pressure mechanism through the wrapping control unit, and maintains the pressure in the elastic control sleeve 4 at this time, so that the lower induction ring 5 can be tightly attached to the annular weld at the lower end of the bottle body 8, the upper induction ring 6 can be tightly attached to the annular weld at the upper end of the bottle body 8, and the side seam induction arc block 7 can be tightly attached to the side seam of the bottle body 8. In the subsequent pressure detection process of the bottle body 8, the induction detection of the weld leakage point is realized, and it can also be effectively applied to bottle bodies 8 with different diameters, increase the detection range of the detection cabinet 1, and promote the economic efficiency of its application.

[0047] Figure 3 - Figure 10 It is shown that the two lower induction rings 5 are embedded with lower induction inserts 51 at one end, the lower induction inserts 51 include lower induction frames embedded in the middle of the lower induction rings 5, and the two lower induction frames are fixedly connected with lower induction diaphragms at one end. The lower induction ring 5 and the lower induction insert 51 can detect the micro-leakage of the annular weld at the lower end of the bottle body 8, and the lower induction frame and the lower induction diaphragm form a sealed structure to reduce the pollution of the detection water to the inside, and promote the durability thereof;

[0048] The two upper induction rings 6 are embedded with upper induction inserts 61 at one end, the upper induction inserts 61 include upper induction frames embedded in the middle of the upper induction rings 6, and the two upper induction frames are fixedly connected with upper induction diaphragms at one end. The upper induction ring 6 and the upper induction insert 61 can detect the micro-leakage of the annular weld at the upper end of the bottle body 8, and the upper induction frame and the upper induction diaphragm form a sealed structure to reduce the pollution of the detection water to the inside, and promote the durability thereof;

[0049] Two side seam induction arc blocks 7 are close to one end of the micro induction frame 71, and the micro induction frame 71 is arranged at the middle line position of the side seam induction arc block 7. Both of the two micro induction frames 71 are fixedly connected with the elastic diaphragm 72 close to one end. The side seam induction arc block 7, the micro induction frame 71 and the elastic diaphragm 72 can detect the micro leakage of the weld on one side or both sides of the axis parallel end face of the bottle body 8. The micro induction frame 71 and the elastic diaphragm 72 form a sealed structure, which reduces the pollution of the detection water to the inside, promotes the durability, and the lower induction diaphragm, the upper induction diaphragm and the elastic diaphragm 72 are made of the same elastic material. When installing, the lower induction diaphragm, the upper induction diaphragm and the elastic diaphragm 72 do not use tight installation, have a loose deformation amount, further promote the durability, and the thickness of the lower induction diaphragm, the upper induction diaphragm and the elastic diaphragm 72 is 0.5-2mm, Figure 2 Figure 10 The lower induction frame, the two lower induction diaphragms, the upper induction frame, the two upper induction diaphragms, the inner wall of the micro induction frame 71 and the two elastic diaphragms 72 are coated with a conductive coating, the thickness of the conductive coating is 15-20μm, and the lower induction frame and the lower induction diaphragm form a lower induction trigger switch through the conductive coating. The upper induction frame and the upper induction diaphragm form an upper induction trigger switch through the conductive coating. The micro induction frame 71 and the elastic diaphragm 72 form a side seam trigger switch through the conductive coating. The input end of the micro leakage trigger unit is respectively connected with the lower induction trigger switch, the upper induction trigger switch and the side seam trigger switch. The lower induction ring 5, the upper induction ring 6 and the side seam induction arc block 7 can effectively detect the micro leakage point of the weld position of the bottle body 8. In the case of high pressure, the micro leakage point of the weld position will spray a small amount of water flow, which will act on the corresponding lower induction diaphragm, upper induction diaphragm or elastic diaphragm 72, causing it to deform concave, and then causing the lower induction diaphragm to abut against the lower induction frame, the upper induction diaphragm to abut against the upper induction frame, or the elastic diaphragm 72 to abut against the inner wall of the micro induction frame 71. The lower induction trigger switch, the upper induction trigger switch or the side seam trigger switch is closed and conducted, triggering the micro leakage trigger unit. The data of the weld micro leakage point in the pressure detection process can be directly obtained, the threshold confirmation step is saved, the pressure detection efficiency is improved, the functionality and intelligence of the detection cabinet 1 are increased, the comprehensiveness of the bottle body 8 detection is promoted, and the reliability and referenceability of the pressure detection data are ensured.

[0050] Figure 2 ​The input terminal of the intelligent detection and processing unit is also connected to a parameter setting unit and an instruction input unit. The input terminal of the parameter setting unit is connected to the data input port on the detection cabinet 1. The data input port can be a USB interface or a physical input terminal such as a keyboard, mouse, or button. The input terminal of the instruction input unit is connected to the control button on the detection cabinet 1. The parameter setting unit can improve the applicability of the intelligent detection and processing unit to different detection standards and bottle bodies 8 of different specifications, expand the application range of the detection cabinet 1, and effectively promote the economy of the detection cabinet 1 while ensuring the intelligence and accuracy of the pressure resistance test.

[0051] Figure 2 The operator inputs parameters for the current pressure resistance test into the intelligent detection and processing unit through the parameter setting unit. These parameters include pressure control parameters, pressure holding parameters, standard range of deformation, bottle body dimensions, and warning and alarm specifications. The intelligent detection and processing unit can process and apply these parameters. The operator can also input start commands, stop commands, termination commands, data confirmation or data modification commands, and alarm cancellation commands into the intelligent detection and processing unit through the command input unit, thereby achieving controllability of the automated pressure resistance test.

[0052] Figure 2 The output of the intelligent detection and processing unit is connected to a pressure resistance detection unit. The output of the pressure resistance detection unit is connected to the water pump pressurization mechanism. The pressure resistance data display unit is connected to the display on the detection cabinet 1. The output of the alarm unit is connected to the alarm and indicator lights on the detection cabinet 1. The over-limit warning setting can generate an over-limit warning feedback when the bottle body 8 exceeds the limit of deformation or a micro-leakage point appears in the weld during the pressure resistance test, and promptly stop the pressure resistance test of the bottle body 8 to recover water resources. While achieving effective detection of the bottle body 8, it can also reduce the risk of the bottle body 8 bursting during the pressure resistance test, further promoting the safety of the pressure resistance test process, and can also effectively recover water resources to avoid water loss after bursting.

[0053] Figure 2 and Figure 10 The upper end of the side seam sensing arc block 7 is fixedly connected to the upper sensing ring 6, and the lower end of the side seam sensing arc block 7 is fixedly connected to the lower sensing ring 5. The lower sensing ring 5 is fixedly connected to the elastic adjustment sleeve 4. The upper sensing ring 6 and the side seam sensing arc block 7 are both in sliding fit with the elastic adjustment sleeve 4. The upper sensing ring 6 and the side seam sensing arc block 7 can achieve sliding fit with the elastic adjustment sleeve 4 through waist groove, dovetail groove or T-shaped groove, so as to ensure position accuracy while giving it a flexible adjustment function.

[0054] A plurality of arc-shaped connecting strips 52 are also fixedly connected between the lower induction ring 5 and the upper induction ring 6, an adaptive cavity is formed in the arc-shaped connecting strip 52, and an adaptive electromagnetic block is fixedly connected to the upper and lower inner walls of the adaptive cavity. The output end of the intelligent detection processing unit is also connected to an adaptive adjustment unit, and the output end of the adaptive adjustment unit is signal-connected to the adaptive electromagnetic block. The cooperation of the arc-shaped connecting strip 52, the adaptive electromagnetic block, and the adaptive adjustment unit can further promote the effectiveness of the detection cabinet 1 in detecting different specifications of the bottle body 8. The adaptive adjustment unit is suitable for the position of the upper and lower end welds of the bottle body 8, and ensures the effectiveness of the detection of the weld position data of the bottle body 8.

[0055] Figure 2 And Figure 10 It is shown that the intelligent detection processing unit can control the adaptive electromagnetic block through the adaptive adjustment unit according to the data set by the parameter setting unit, so that the upper induction ring 6 can be driven to move up and down in the elastic regulation sleeve 4, and the side seam induction arc block 7 can produce corresponding expansion and elongation deformation, so that the upper induction ring 6 can adapt to different sizes of the bottle body 8 and effectively detect the micro-leakage of the annular weld on the upper end of the bottle body 8. When the adaptive adjustment unit controls two adaptive electromagnetic blocks located in the same arc-shaped connecting strip 52 to produce repelling electromagnetic action, the upper induction ring 6 will move upwards and produce elongation deformation of the side seam induction arc block 7 in linkage, which is suitable for higher size of the bottle body 8. When the adaptive adjustment unit controls two adaptive electromagnetic blocks located in the same arc-shaped connecting strip 52 to produce attracting electromagnetic action, the upper induction ring 6 will move downwards and produce contraction deformation of the side seam induction arc block 7 in linkage, which is suitable for lower size of the bottle body 8.

[0056] Figure 1 - Figure 3 And Figure 9 It is shown that the detection cabinet 2 is provided with a plurality of detection water pipes 22 connected with the water pump pressure mechanism, and the detection water pipes 22 are correspondingly arranged with the detection cylinder 21. The outer end of the detection water pipe 22 is fixedly installed with a water pressure sensor. The input end of the intelligent detection processing unit is also connected with a water pressure sensing unit, and the input end of the water pressure sensing unit is signal-connected with the water pressure sensor. The water pressure sensing unit and the water pressure sensor can realize accurate regulation and feedback during the pressure detection process of the bottle body 8, thereby improving the accuracy of the regulation and the effectiveness of the pressure detection data.

[0057] Figure 2It is shown that the intelligent detection processing unit can control the water pump pressure mechanism through the pressure detection unit, so that it can detect the water pipe 22 to the bottle body 8 into the detection of water, and constantly pressurize, through the water pressure sensing unit to the intelligent detection processing unit transmission water pressure sensor transmission water pressure data, the intelligent detection processing unit can realize the automatic control of the bottle body 8 pressure detection, and in the process of detection, can be through the pressure data display unit to the display output pressure detection process control pressure data and related detection data, so that the operator can judge the working state of the detection cabinet 1 according to the displayed data.

[0058] Figure 1 - Figure 10 It is shown that when the bottle body 8 is pressure-resistant and has no weld micro-leakage point, the bottle body 8 will not produce bottle body deformation or the bottle body 8 produces a small amount of bottle body deformation during pressure detection. The pressure sensor located in the elastic control sleeve 4 will transmit the pressure data in the elastic control sleeve 4 to the deformation pressure sensing unit in real time during the detection process. The intelligent detection processing unit judges the bottle body deformation of the bottle body 8 according to the pressure data transmitted by the deformation pressure sensing unit. When there is no deformation or the deformation is within the standard range, it is determined that the bottle body 8 is pressure-resistant. The detection data and the bottle body deformation data of the bottle body 8 are output to the display through the pressure data display unit. When the weld on the bottle body 8 does not produce micro-leakage under high pressure, the lower sensing trigger switch, the upper sensing trigger switch and the side seam trigger switch are all in the off state, and will not trigger the micro-leakage trigger unit. The intelligent detection processing unit judges the good position of the bottle body 8 weld during pressure detection according to the trigger data of the micro-leakage trigger unit not received, and outputs the detection data to the display through the pressure data display unit, so that the operator can obtain the detection data of the bottle body 8 in time. After the detection is completed, the intelligent detection processing unit can output the results of the pressure detection of the bottle body 8 through the pressure data display unit.

[0059] When the bottle body 8 generates bottle body deformation, the bottle body deformation of the bottle body 8 will continuously act on the lower induction insert 51 and the side seam induction arc block 7, and then be transmitted to the elastic control sleeve 4, so that the elastic control sleeve 4 generates extrusion effect of bottle body deformation of the bottle body 8, generates local shrinkage deformation, so that the internal pressure increases, the deformation pressure sensing unit can receive the pressure data transmitted by the pressure sensor, and convert and transmit it to the intelligent detection processing unit. The intelligent detection processing unit judges the bottle body deformation variable data of the bottle body 8 according to the pressure data, and when the bottle body deformation variable data exceeds the standard range, the intelligent detection processing unit sends the data of the over-limit early warning to the over-limit early warning unit, and at the same time transmits the related detection data to the pressure resistance data display unit. The over-limit early warning unit transmits the mark of over-limit data and the pop-up data to the pressure resistance data display unit. The operator judges and controls the detection according to the display of the pop-up data and the over-limit data, and transmits the instruction data of whether to directly terminate the detection to the instruction input unit through the control button. The intelligent detection processing unit executes the operation process according to the instruction, and the over-limit early warning unit also sends an alarm signal to the alarm unit, so that the alarm unit controls the indicator light to display the lamp indication that the bottle body deformation variable of the bottle body 8 exceeds the standard range at this time.

[0060] When the operator inputs the instruction for continuous detection, the intelligent detection processing unit will also send an alarm control signal to the alarm unit during the continuous pressure resistance detection of the bottle body 8 by the cooperation of the pressure resistance detection unit and the water pressure sensing unit, so that the alarm unit controls the alarm to start and generates continuous alarm data. Through the pressure resistance data display unit and the display, the signal of moving away from the detection cabinet 1 and the detection cabinet 2 is displayed to the operator. While ensuring the continuous pressure resistance detection and effectively obtaining the limit pressure value of the bottle body 8, it can also effectively reduce the personal risk caused by the explosion of the bottle body 8 in the process of continuous pressure increase or pressure maintenance, increase the safety of continuous monitoring, and after the subsequent pressure resistance test is completed or the bottle body 8 explodes, the intelligent detection processing unit stops the alarm signal of the alarm by controlling the alarm unit, indicating that the detection is completed, so that the operator can approach the detection cabinet 1 and the detection cabinet 2 to read the detection data and recycle the bottle body 8 and other actions;

[0061] When the operator inputs a stop detection instruction, the intelligent detection processing unit controls the water pump pressurizing mechanism to produce a pressure relief action through the pressure resistance detection unit, stops the continuous pressurization or pressure maintenance action on the bottle body 8, and after the pressure resistance detection unit control is completed, controls the water pump extrusion mechanism through the wrapping control unit to produce a pressure relief control on the elastic control sleeve 4, so that the elastic control sleeve 4 produces a contraction action, releases the wrapping of the bottle body 8 by the lower induction ring 5, the upper induction ring 6 and the side seam induction arc block 7, and outputs the report of this detection of the bottle body 8 through the pressure resistance data display unit. Other normally positioned bottle bodies 8 can continue to be detected, effectively avoiding the risk of bottle body 8 explosion caused by continuous detection, thereby increasing the safety of the pressure resistance detection process, having the function of intelligent explosion prevention according to detection needs, reducing the cost of safety detection and explosion prevention, while achieving synchronous data detection, effectively realizing the safety detection guarantee function.

[0062] When the bottle body 8 has a micro-leakage point in the weld, during the pressure resistance test, when the ring-shaped weld at the lower end of the bottle body 8, the ring-shaped weld at the upper end of the bottle body 8 or the weld on the end face parallel to the axis has a micro-leakage point, during the process of continuous pressurization or pressure maintenance, the water inside the bottle body 8 will form a fine water column and be sprayed out through the micro-leakage point, and act on the corresponding lower induction diaphragm, upper induction diaphragm or elastic diaphragm 72, then cause the lower induction diaphragm, upper induction diaphragm or elastic diaphragm 72 to produce local deformation, the lower induction diaphragm continuously approaches the lower induction frame until it contacts the lower induction frame; the upper induction diaphragm continuously approaches the upper induction frame until it contacts the upper induction frame; or the elastic diaphragm 72 continuously approaches the micro-quantity induction frame 71 until it abuts against the micro-quantity induction frame 71, and under the action of the conductive coating, causes the lower induction trigger switch, upper induction trigger switch or side seam trigger switch to produce conduction triggering, so that the micro-leakage trigger unit transmits the trigger data of the micro-leakage point to the intelligent detection processing unit, the intelligent detection processing unit judges according to the data that the bottle body 8 has a weld leakage at this time, and synchronizes the detection data to the pressure resistance data display unit, the pressure resistance data display unit displays the abnormal detection data through the display, and at the same time, the intelligent detection processing unit controls the alarm and indicator light to act through the alarm unit, displays the state at this time to the operator, and reminds the operator to respond in time to terminate the pressure resistance detection of the bottle body 8.

[0063] The third embodiment:

[0064] Figure 6 - Figure 8 and Figure 11The application discloses a perfluorohexanone fire extinguisher pressure resistance detection device. The device can be applied to a perfluorohexanone cabinet fire extinguishing system, and realizes safe detection of a perfluorohexanone fire extinguisher in an extreme environment. The device is expanded for application, and a user can customize the device according to requirements to ensure the effectiveness of cost control. A detection cylinder 21 is fixedly installed with an adapter pad 31 matched with a wrapping shell 3. The adapter pad 31 is inlaid with an induction micro-control chip. An input end of the induction micro-control chip is respectively connected with a pressure sensor, a lower induction ring 5, an upper induction ring 6 and a side seam induction arc block 7. An output end of the induction micro-control chip is connected with a micro-leakage trigger unit, and the output end of the induction micro-control chip is further connected with an expansion conversion port. The adapter pad 31 can realize effective transmission of induction detection data, and can realize reuse of the lower induction ring 5, the upper induction ring 6 and the side seam induction arc block 7, thereby increasing the functionality of the device. The device can continuously monitor and induce the perfluorohexanone fire extinguisher during application, thereby ensuring the application safety of the perfluorohexanone fire extinguisher.

[0065] Figure 6 - Figure 8 and Figure 11 The wrapping shell 3, the elastic regulation sleeve 4, the lower induction ring 5, the upper induction ring 6 and the side seam induction arc block 7 are matched with the adapter pad 31 to form an independent induction detection module. The regulation pipe 41 directly regulates the pressure in the elastic regulation sleeve 4 to a stable and appropriate value according to the specification of the perfluorohexanone fire extinguisher, and keeps the pressure in the elastic regulation sleeve 4, so that the elastic regulation sleeve 4, the upper induction ring 6 and the side seam induction arc block 7 can be tightly clamped outside the perfluorohexanone fire extinguisher and correspond to the welding seam position of the perfluorohexanone fire extinguisher, so that the perfluorohexanone fire extinguisher can be effectively installed in the wrapping shell 3. Then, the module realizes signal connection of the pressure sensor, the lower induction ring 5, the upper induction ring 6 and the side seam induction arc block 7 with the perfluorohexanone cabinet fire extinguishing system through the expansion conversion port of the adapter pad 31, thereby realizing safe detection of the perfluorohexanone fire extinguisher in an extreme environment.

[0066] The perfluorohexanone fire extinguisher bears the triggering mechanism of the perfluorohexanone cabinet fire extinguishing system, and quickly releases the perfluorohexanone extinguishing agent. At this time, the nitrogen in the pressure storage bottle is activated, and the extinguishing agent is compressed into the pipeline and sprayed out in a short time, resulting in a sudden increase in internal pressure. This instantaneous high pressure may exceed the regular working pressure designed for the fire extinguisher, especially in the case of emergency start or multiple consecutive starts. Or the temperature of the environment where the perfluorohexanone fire extinguisher is located rises, and the internal extinguishing agent expands due to heat, superimposing the original nitrogen pressure, which may cause the overall pressure to exceed the safety threshold. Then the sensing and detecting module formed by the wrapping shell 3, the adapter pad 31, the elastic regulating sleeve 4, the lower induction ring 5, the upper induction ring 6 and the side seam induction arc block 7 can form a signal connection with the perfluorohexanone cabinet fire extinguishing system through the expansion conversion port of the adapter pad 31, and continuously detect the perfluorohexanone fire extinguisher. After the occurrence of leakage triggering, the signal can be directly transmitted to the perfluorohexanone cabinet fire extinguishing system, which can reduce the maintenance difficulty of the perfluorohexanone fire extinguisher, increase the detection sensitivity of the micro-leakage point, and also ensure the safety and effectiveness of the perfluorohexanone cabinet fire extinguishing system. Continuous application can ensure the effectiveness of the subsequent perfluorohexanone fire extinguisher extinguishing action.

[0067] In combination with the current actual demand, the protection scope of the above-mentioned embodiments of the present application is not limited thereto, various changes made within the knowledge range of those skilled in the art without departing from the concept of the present application still fall within the protection scope of the present application.
