Description

Technical Field

[0001] The invention belongs to the technical field of safety protection, and in particular relates to a safety protection device for campus infrastructure reconstruction. Background Art

[0002] During the process of infrastructure renovation, in order to improve the safety of on-site construction, protective devices are often needed to protect the foundation pit and safe construction range of the construction site. Especially on campus, there are many students passing by. If protective devices are not installed, it is easy for students to accidentally break in, which may cause harm to the students.

[0003] However, the existing protective devices have disadvantages during use. The connection of the protective devices is mostly connected by bolts, which is cumbersome to assemble and not conducive to the flexible use of the protective devices. In addition, the protective devices in the prior art can only play the role of enclosure and blocking. However, in reality, many college students like to play with their mobile phones while walking, so they are prone to walking off the track or not being able to fully consider the enclosure obstacles on the road. At this time, the enclosure set up will directly cause harm to the students, and then cause unnecessary trouble to the users. Summary of the invention

[0004] The purpose of the present invention is to provide a safety protection device for campus infrastructure reconstruction, which can solve the problems of inconvenient disassembly and assembly and failure to provide early warning for infrastructure protection devices in the prior art.

[0005] In order to achieve the above object, a technical solution provided by a specific embodiment of the present invention is as follows:

[0006] A safety protection device for campus infrastructure reconstruction, comprising: a supporting column, an inclined connection mechanism, a fixed conveying mechanism and a toothed sliding mechanism;

[0007] Warning lights are installed on the plurality of support columns;

[0008] The tilting connection mechanism is installed between a pair of the supporting columns, and the tilting connection mechanism includes a pair of connecting rotating plates, and grooves are cut at the ends of the pair of connecting rotating plates close to each other, and a rotating shaft is arranged in the groove, and both ends of the rotating shaft are fixed to the connecting rotating plates, and a pair of rotating shafts are rotatably connected with rotating toothed connecting blocks, and a pair of connecting rotating plates are cut with water flow grooves at the bottom, and the connecting rotating plates are also cut with contraction grooves;

[0009] The fixed conveying mechanism is installed in the supporting column, and the fixed conveying mechanism includes a rotating threaded tube, one end of which is fixedly connected to a driving motor, and the driving motor is installed in the supporting column, and a lifting slider is threadedly connected to the end of the rotating threaded tube away from the driving motor, and connecting rods are fixed on both sides of the lifting slider, and a corner joint is installed at the other end of the connecting rod;

[0010] The toothed sliding mechanism is installed in the contraction groove, and is used to fix a pair of connecting rotating plates so that their included angles will not change, thereby achieving the function of fixing a pair of supporting columns and the connecting rotating plates.

[0011] In one or more embodiments of the present invention, a dispersion chamber is excavated in the support column, which is used to disperse the water flow to the dust reduction nozzle and the warning nozzle for spraying, so that the dust reduction nozzle can spray water mist outward to achieve dust reduction on the construction site, and prevent the dust from affecting the students passing by, while the water mist sprayed by the warning nozzle can warn the students passing by, and prevent the students from not observing the device in time because of playing with mobile phones, so that the device also has the functions of dust reduction and warning;

[0012] The side walls of the dispersion chamber are respectively installed with dust reduction nozzles and warning nozzles, both of which are used to spray water mist outward, so as to achieve the functions of dust reduction and warning students and improve the practicability of the device. The dust reduction nozzles and warning nozzles are respectively installed on both sides of the supporting columns. Because the students and the construction site must belong to the two sides of the supporting columns, the dust reduction nozzles and the warning nozzles will not spray to the same side.

[0013] In one or more embodiments of the present invention, a pair of supporting cross bars are fixed on the supporting column, which are used to support the upper plug rod to prevent the upper plug rod from falling off, and also have the function of limiting the connection rotating plate, so that the connection rotating plate cannot be further raised, thereby clamping the corner joint and the connection rotating plate to avoid leakage of the conveyed water flow. An upper plug rod is arranged on one side of the supporting cross bar, which is used to be inserted into the insertion hole on the connection rotating plate, so as to promote the sliding of the sliding push rod, thereby enabling the engaging rack to be clamped in the tooth groove, thereby realizing the fixation of a pair of connection rotating plates and the rotating toothed connecting block, preventing the angle between the connection rotating plate and the rotating toothed connecting block from changing again, thereby also improving the stability of the supporting column;

[0014] A sliding positioning block is slidingly arranged inside the upper insertion rod, and a connecting column is fixedly connected between the sliding positioning block and the supporting cross bar, so that the upper insertion rod can slide up and down, thereby facilitating the installation of connecting rotating plates at different heights, thereby improving the applicability of the device. A positioning screw is threadedly connected to the sliding positioning block, which is used to fix the upper insertion rod so that it can no longer slide up and down, thereby improving the stability of the device.

[0015] In one or more embodiments of the present invention, a delivery hose is connected between the pair of connecting rotating plates, and the two ends of the delivery hose are respectively connected to a pair of water flow grooves, so that water can be transported through the pair of water flow grooves and the delivery hose, thereby facilitating the water flow from one delivery cavity to another delivery cavity, thereby enabling multiple rotating threaded tubes to transport water upward, and because the delivery hose is a hose, the change in the angle of the pair of connecting rotating plates will not affect the delivery of water;

[0016] A pair of the connecting rotating plates are both provided with insertion holes matching the upper insertion rod for inserting the upper insertion rod, so that the sliding push rod can be pushed by the upper insertion rod, so that the sliding push rod can slide, thereby driving the movement of the supporting arc block and the engaging rack, so that the engaging rack can be stuck in the tooth groove, thereby achieving the effect of fixing the connecting rotating plate and rotating the toothed connecting block.

[0017] In one or more embodiments of the present invention, a pair of engaging grooves are formed on the rotating toothed connecting block, and a plurality of evenly distributed tooth grooves are formed on the side walls of the engaging grooves for engaging the racks, so that the connecting rotating plate can no longer rotate, thereby fixing the angle between the connecting rotating plate and the rotating toothed connecting block, and thus fixing the position of the supporting column, so that the supporting column will no longer shake, thereby improving the stability of the device.

[0018] In one or more embodiments of the present invention, a plurality of first sealed bearings are fixedly connected between one end of the rotating threaded tube close to the driving motor and the supporting column, which are used to fix the rotating threaded tube to ensure the rotational stability of the rotating threaded tube and prevent water leakage, so that the water flow delivered by the rotating threaded tube can be sprayed out from the dust reduction nozzle and the warning nozzle. A plurality of evenly distributed delivery holes are also drilled on the rotating threaded tube, and the delivery holes are drilled in the dispersion chamber to deliver the water flow delivered by the rotating threaded tube into the dispersion chamber, so that the dust reduction nozzle and the warning nozzle can spray water mist outward, thereby playing the role of dust reduction and warning.

[0019] In one or more embodiments of the present invention, a support pad is fixedly connected to the bottom of the support column, which is used to support the support column and ensure the stability of the support column so that the support column will not fall over. A conveying cavity is drilled on the support pad, and the rotating threaded pipe is connected to the conveying cavity for conveying water flow, so that the water flow can flow into the rotating threaded pipe, and then be conveniently conveyed to the dust suppression nozzle and the warning nozzle for spraying;

[0020] A second sealing bearing is fixedly connected between the rotating threaded tube and the support pad, which is used to fix one end of the rotating threaded tube so that the rotation of the rotating threaded tube will not be affected and the water flow in the conveying chamber will not leak, thereby improving the sealing performance of the device. A connecting hose is fixedly connected between the support pad and a pair of angle joints, which is used to connect the angle joint and the conveying chamber, thereby facilitating the flow of water. Because the connecting hose is a flexible hose, the lifting and lowering movement of the angle joint will not affect the connecting hose in conveying water.

[0021] In one or more embodiments of the present invention, the support plate is threaded with a plurality of fixing screws for being inserted into the ground, thereby facilitating the fixing of the support plate and further ensuring the stability of the supporting column. A fixing cone head is fixed to the bottom of the fixing screw to facilitate driving the fixing screw downward. A sealing rubber sleeve is provided between the corner joint and the connecting rotating plate. The sealing rubber sleeve is fixed in the water flow trough to improve the sealing between the corner joint and the connecting rotating plate and avoid water leakage.

[0022] In one or more embodiments of the present invention, the meshing sliding mechanism includes a sliding push rod for driving the movement of the supporting arc block and the engaging rack. The sliding push rod is arranged at an oblique edge at one end away from the rotating meshing connection block, so that the sliding push rod can be pushed to slide during the descent of the upper insertion rod, thereby facilitating the sliding of the supporting arc block and the engaging rack. A sliding groove is also cut on the connecting rotating plate to provide space for the sliding of the extrusion block.

[0023] A pair of extrusion blocks are arranged in the slide groove for squeezing the push spring. The pair of extrusion blocks are fixed on the sliding push rod. A push spring is fixedly connected between the extrusion block and the connecting rotating plate for pushing the extrusion block, so that the sliding push rod is reset by the extrusion block, and the engaging rack is no longer stuck in the tooth groove, thereby achieving the effect of releasing the fixation and facilitating subsequent repeated use.

[0024] In one or more embodiments of the present invention, a supporting arc block is fixed to one end of the sliding push rod close to the rotating toothed connecting block, which is used to support multiple engaging racks and drive the engaging racks to move. Multiple evenly distributed engaging racks are installed on the supporting arc block, which are used to snap into the tooth grooves, so that the angle between the connecting rotating plate and the rotating toothed connecting block will no longer change, thereby fixing the supporting column so that the supporting column can no longer move, thereby achieving a fixing effect.

[0025] Compared with the prior art, the present invention improves the functionality of the infrastructure protection device by setting up corresponding mechanisms, so that it can not only be quickly disassembled and assembled, but also serve as a warning after installation and use, so that students passing by on campus will not approach, thereby avoiding safety accidents and reducing unnecessary troubles for users.

DETAILED DESCRIPTION

[0039] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0040] like Figure 1-Figure 10 As shown, a safety protection device for campus infrastructure reconstruction in one embodiment of the present invention includes: a supporting column 1, an inclined connection mechanism 2, a fixed conveying mechanism 3 and a geared sliding mechanism 4.

[0041] like Figure 1-Figure 2 As shown, warning lights 101 are installed on multiple support columns 1 to warn students passing by, reduce the probability of students mistakenly entering, and thus reduce the probability of students getting injured. A dispersion chamber 102 is excavated in the support column 1 to disperse the water flow to the dust reduction nozzle 103 and the warning nozzle 104 for spraying, so that the dust reduction nozzle 103 can spray water mist outward to achieve dust reduction on the construction site and prevent the dust from affecting the students passing by. The water mist sprayed by the warning nozzle 104 can warn the students passing by to prevent the students from not observing the device in time because of playing with their mobile phones, so that the device also has the functions of dust reduction and warning.

[0042] like Figure 1-Figure 8As shown, the side walls of the dispersion chamber 102 are respectively installed with dust reduction nozzles 103 and warning nozzles 104, both of which are used to spray water mist outward, so as to achieve the functions of dust reduction and warning students and improve the practicality of the device. The dust reduction nozzles 103 and the warning nozzles 104 are respectively installed on both sides of the supporting column 1. Because the students and the construction site must belong to the two sides of the supporting column 1, the dust reduction nozzles 103 and the warning nozzles 104 will not spray to the same side.

[0043] like Figure 1-Figure 9 As shown, a pair of supporting cross bars 105 are fixed on the support column 1, which are used to support the upper plug rod 106 to prevent the upper plug rod 106 from falling off, and also have the function of limiting the connection rotating plate 201, so that the connection rotating plate 201 cannot continue to rise, thereby making the corner joint 305 and the connection rotating plate 201 clamped to prevent leakage of the conveyed water flow. An upper plug rod 106 is provided on one side of the supporting cross bar 105, which is used to be inserted into the insertion hole on the connection rotating plate 201, so as to push the sliding push rod 401 to slide, thereby making the clamping rack 406 clamped in the tooth groove 207, so as to achieve the fixation of a pair of connection rotating plates 201 and the rotating toothed connection block 203, and prevent the angle between the connection rotating plate 201 and the rotating toothed connection block 203 from changing again, thereby also improving the stability of the support column 1.

[0044] Among them, a sliding positioning block 107 is slidably provided inside the upper insertion rod 106, and a connecting column 108 is fixedly connected between the sliding positioning block 107 and the supporting cross bar 105, so that the upper insertion rod 106 can slide up and down, thereby facilitating the installation of the connecting rotating plate 201 at different heights, thereby improving the applicability of the device. A positioning screw 109 is threadedly connected to the sliding positioning block 107, which is used to fix the upper insertion rod 106 so that it can no longer slide up and down, thereby improving the stability of the device.

[0045] like Figure 1-Figure 6 As shown, the tilting connection mechanism 2 is installed between a pair of supporting columns 1, and the tilting connection mechanism 2 includes a pair of connecting rotating plates 201, which are used to connect the pair of supporting columns 1, so that the device is linked as a whole, thereby reducing the probability of the device tipping over. A groove is cut at one end of the pair of connecting rotating plates 201 close to each other, and a rotating shaft 202 is arranged in the groove, which is used to support the rotating toothed connection block 203 and facilitate the rotation of the rotating toothed connection block 203, thereby facilitating the adjustment of the position of the supporting column 1. Both ends of the rotating shaft 202 are fixed on the connecting rotating plates 201, and the pair of rotating shafts 202 are rotatably connected with the rotating toothed connection blocks 203.

[0046] Specifically, a pair of connecting rotating plates 201 are provided at the bottom with water flow grooves 204 for conveying water so that the water can flow in the entire device, so that multiple dust suppression nozzles 103 and warning nozzles 104 can spray water outward. The connecting rotating plates 201 are also provided with contraction grooves to provide space for the sliding of the sliding push rod 401.

[0047] like Figure 1-Figure 6 As shown, a delivery hose 205 is connected between a pair of connecting rotating plates 201, and both ends of the delivery hose 205 are respectively connected to a pair of water flow grooves 204, so that water can be transported through a pair of water flow grooves 204 and the delivery hose 205, thereby facilitating the transportation of water from one delivery cavity 310 to another delivery cavity 310, thereby enabling multiple rotating threaded tubes 301 to transport water upward, and because the delivery hose 205 is a hose, the change in the angle of the pair of connecting rotating plates 201 will not affect the transportation of water.

[0048] like Figure 1-Figure 6 As shown, a pair of connecting rotating plates 201 are both provided with insertion holes matching the upper insertion rod 106 for inserting the upper insertion rod 106, so that the sliding push rod 401 can be pushed by the upper insertion rod 106, so that the sliding push rod 401 can slide, thereby driving the movement of the supporting arc block 405 and the engaging rack 406, so that the engaging rack 406 can be stuck in the tooth groove 207, thereby achieving the effect of fixing the angle between the connecting rotating plate 201 and the rotating toothed connecting block 203.

[0049] like Fig.10 As shown, a pair of engaging grooves 206 are cut on the rotating toothed connecting block 203, and a plurality of evenly distributed tooth grooves 207 are cut on the side walls of the engaging grooves 206 for engaging the rack 406, so that the connecting rotating plate 201 can no longer rotate, thereby fixing the angle between the connecting rotating plate 201 and the rotating toothed connecting block 203, and also fixing the position of the supporting column 1, so that the supporting column 1 will no longer shake, thereby improving the stability of the device.

[0050] like Figure 1-Figure 4 As shown, the fixed conveying mechanism 3 is installed in the supporting column 1, and the fixed conveying mechanism 3 includes a rotating threaded tube 301, which is used to drive the lifting slider 303 to move up and down, and also has the function of conveying water. One end of the rotating threaded tube 301 is fixedly connected to a driving motor 302, which is used to drive the rotating threaded tube 301 to rotate, thereby providing power for the lifting and moving of the lifting slider 303, and the driving motor 302 is installed in the supporting column 1. The lifting slider 303 is threadedly connected on the end of the rotating threaded tube 301 away from the driving motor 302, which is used to support a pair of connecting rods 304 and a corner joint 305, and has the function of driving them to move up and down.

[0051] like Figure 1-Figure 4As shown, connecting rods 304 are fixed on both sides of the lifting slider 303 for supporting the corner joint 305, and the other end of the connecting rod 304 is installed with a corner joint 305 for conveying water so that the water can flow in the overall device.

[0052] Among them, a plurality of first sealed bearings 306 are fixedly connected between one end of the rotating threaded tube 301 close to the driving motor 302 and the supporting column 1, which are used to fix the rotating threaded tube 301 to ensure the rotation stability of the rotating threaded tube 301 and prevent water leakage, so that the water flow transported by the rotating threaded tube 301 can be sprayed out from the dust suppression nozzle 103 and the warning nozzle 104.

[0053] Specifically, a plurality of evenly distributed delivery holes 307 are drilled on the rotating threaded tube 301. The delivery holes 307 are drilled in the dispersion chamber 102 and are used to deliver the water flow delivered by the rotating threaded tube 301 into the dispersion chamber 102, so that the dust reduction nozzle 103 and the warning nozzle 104 can spray water mist outward, thereby playing the role of dust reduction and warning.

[0054] like Figure 1-Figure 7 As shown, a support pad 308 is fixedly connected to the bottom of the support column 1, which is used to support the support column 1 and ensure the stability of the support column 1 so that the support column 1 will not fall over. A delivery cavity 310 is excavated on the support pad 308, and the rotating threaded tube 301 is connected to the delivery cavity 310 for delivering water, so that the water can flow into the rotating threaded tube 301, and then be conveniently delivered to the dust suppression nozzle 103 and the warning nozzle 104 for spraying.

[0055] Among them, a second sealing bearing 309 is fixedly connected between the rotating threaded tube 301 and the supporting pad 308, which is used to fix one end of the rotating threaded tube 301 so that the rotation of the rotating threaded tube 301 will not be affected and the water flow in the conveying cavity 310 will not leak, thereby improving the sealing performance of the device.

[0056] like Figure 1-Figure 4 As shown, a connecting hose 311 is fixedly connected between the support pad 308 and a pair of corner joints 305, which is used to connect the corner joint 305 and the conveying chamber 310, so as to facilitate the flow of water. Moreover, because the connecting hose 311 is a hose, the lifting and lowering movement of the corner joint 305 will not affect the connecting hose 311 in conveying water.

[0057] In addition, a plurality of fixing screws 312 are threadedly connected on the support pad 308, which are used to be inserted into the ground, so as to facilitate fixing the support pad 308, thereby ensuring the stability of the support column 1, and a fixing cone head 313 is fixed at the bottom of the fixing screw 312, so as to facilitate the fixing screw 312 to be driven downward. A sealing rubber sleeve 314 is provided between the corner joint 305 and the connecting rotating plate 201, and the sealing rubber sleeve 314 is fixed in the water flow groove 204 to improve the sealing between the corner joint 305 and the connecting rotating plate 201 to prevent water leakage.

[0058] like Figure 1-Figure 5 As shown, the toothed sliding mechanism 4 is installed in the contraction groove, and the toothed sliding mechanism 4 is used to fix a pair of connecting rotating plates 201 so that their included angles will not change, thereby achieving the function of fixing a pair of supporting columns 1 and the connecting rotating plates 201. The toothed sliding mechanism 4 includes a sliding push rod 401, which is used to drive the movement of the supporting arc block 405 and the engaging rack 406. The sliding push rod 401 is arranged at an end oblique edge away from the rotating toothed connecting block 203, so that the upper insertion rod 106 can push the sliding push rod 401 to slide during the descent process, thereby facilitating the sliding of the supporting arc block 405 and the engaging rack 406. A sliding groove 402 is also excavated on the connecting rotating plate 201 to provide space for the sliding of the extrusion block 403.

[0059] like Figure 1-Figure 5 As shown, a pair of extrusion blocks 403 are provided in the slide groove 402 for squeezing the push spring 404. The pair of extrusion blocks 403 are fixed on the sliding push rod 401. A push spring 404 is fixedly connected between the extrusion block 403 and the connecting rotating plate 201 for pushing the extrusion block 403, so that the sliding push rod 401 is reset by the extrusion block 403, and then the engaging rack 406 is no longer stuck in the tooth groove 207, so as to realize the effect of releasing the fixation and facilitate the subsequent reuse.

[0060] like Figure 1-Figure 10 As shown, a support arc block 405 is fixed at one end of the sliding push rod 401 close to the rotating toothed connection block 203, which is used to support a plurality of engaging racks 406 and drive the engaging racks 406 to move, and a plurality of evenly distributed engaging racks 406 are installed on the support arc block 405. It is used to be inserted into the tooth groove 207, so that the angle between the connecting rotating plate 201 and the rotating toothed connection block 203 will not change, thereby fixing the support column 1, so that the support column 1 can no longer move, and the fixing effect is achieved.

[0061] When in use, the fixed conveying mechanism 3 is first placed between a pair of supporting columns 1, and then the upper insertion rod 106 is aligned with the insertion hole on the connecting rotating plate 201 and inserted, so that the pair of connecting rotating plates 201 can be fixed between the pair of supporting columns 1, and then the driving motor 302 is started, and the rotating threaded tube 301 is driven to rotate by the driving motor 302, and then the threaded connection between the rotating threaded tube 301 and the lifting slider 303 is made so that the lifting slider 303 can be raised, and then the connecting rod 304 and the corner joint 305 are driven to rise by the lifting slider 303 so that the corner joint 305 can be inserted into the connecting rotating plate 201, and the corner joint 305 is connected to the water flow trough 204, and then the continued rise of the lifting slider 303 will drive the pair of connecting rotating plates 201 to rise;

[0062] Then the upper insertion rod 106 is inserted into a deeper position of the insertion hole on the connecting rotating plate 201, and at this time the upper insertion rod 106 will push the sliding push rod 401, and the sliding push rod 401 can slide by using the slope at one end of the sliding push rod 401, and then the supporting arc block 405 and the engaging rack 406 are driven by the sliding push rod 401 to be engaged in the tooth groove 207, so as to achieve the function of fixing the rotating engaging connecting block 203 and a pair of connecting rotating plates 201, so as to prevent them from changing their angles again, and achieve the fixing effect, and the supporting pad 308 can be fixed to the ground by the fixing screw 312 and the fixing cone head 313, so that the supporting column 1 can no longer move;

[0063] Then, the subsequent connecting rotating plate 201 first aligns the corner joint 305 with the water flow groove 204 and inserts it, and then slides the upper plug rod 106 so that the upper plug rod 106 can be inserted into the insertion hole on the connecting rotating plate 201, and pushes the engaging rack 406 to be stuck in the tooth groove 207 to achieve fixation, and finally the fixing effect is achieved by positioning the screw 109 to prevent the upper plug rod 106 from sliding up and down again, thereby affecting the stability of the device, so that the device can play a role of blocking protection, and the warning light 101 can also play a warning role;

[0064] Moreover, a water delivery pipe is connected through the corner joint 305, and spraying water is delivered to the corner joint 305 through the water delivery pipe. The water flow will first enter one of the support pads 308, and then be delivered to the dispersion chamber 102 through the rotating threaded tube 301 and multiple delivery holes 307, and finally can be sprayed out through the dust reduction nozzle 103 and the warning nozzle 104. The water mist sprayed by the dust reduction nozzle 103 can reduce dust on the construction site to avoid large dust caused by infrastructure reconstruction and will not affect the students passing by. The warning nozzle 104 can remind the students who are playing with their mobile phones, so that even if the students do not observe the supporting column 1 and the connecting rotating plate 201, they can still feel the falling water mist, thereby observing the surrounding environment to avoid causing harm.

[0065] In addition, the conveying water flow can also be conveyed to another supporting column 1 through the corner joint 305, the water flow trough 204 and the conveying hose 205, so that after the device is installed, only one corner joint 305 is needed to be connected to the conveying water pipe to enable the dust suppression nozzles 103 and the warning nozzles 104 on multiple supporting columns 1 to spray water mist outward, and at this time, an extra unused corner joint 305 needs to be blocked to avoid water leakage, thereby protecting the infrastructure renovation construction site and protecting the students passing by from being harmed.

[0066] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0067] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution.
