Description

Technical Field

[0001] The present invention relates to the technical field of mine sump cleaning, and specifically, to an efficient mine sump cleaning device. Background Art

[0002] The central sump in a coal mine underground is an important and indispensable facility in the coal mine production system. Its main function is to collect and store the groundwater gushing out in the mine and various wastewaters generated during the coal mining process, including spray dust suppression wastewater, equipment flushing wastewater, and coal mining wastewater, etc. After the wastewater is settled and clarified in the sump, it can be reused for surface and underground production activities, thus realizing the recycling of resources. However, with the extension of the sump operation time, a large amount of sediment coal sludge gradually accumulates inside it, resulting in a significant decrease in the effective water storage capacity. To ensure that the sump has the necessary water storage capacity, and thus guarantee the continuity and safety of coal mine production, the cleaning of sump coal sludge has become an important and periodic task.

[0003] In recent years, the coal sludge cleaning equipment for coal mine underground sumps has developed rapidly, and the mechanized cleaning technology has gradually replaced the traditional manual operation. To adapt to sumps of different widths, existing equipment generally drives the sludge collection mechanism through hydraulic rods to achieve telescopic adjustment, so as to increase the operation coverage area of the sludge collection mechanism, and thus effectively clean a wider area in a single movement. However, the operation of the hydraulic rod usually relies on manual control. On the one hand, because the operation environment of the coal mine underground sump is complex and changeable, the width, bending degree of the sump, and possible obstacles are all unpredictable. This environmental characteristic requires the equipment to have high operation flexibility. Manual control of the hydraulic rod can adjust the length of the sludge collection mechanism according to the real-time situation to meet different cleaning requirements. On the other hand, during the coal mine sump cleaning process, the operation state of the equipment and environmental changes have a large degree of immediacy. Manual control of the hydraulic rod can quickly respond to the on-site situation, such as adjusting the equipment posture, avoiding obstacles or preventing collisions. Compared with a fully automated system, manual operation has higher flexibility and adaptability.

[0004] Although operators are usually configured during the operation of the cleaning equipment, their responsibilities are not limited to controlling the hydraulic rod. They also need to observe and regulate the operation states of other components of the equipment. In the environment of a coal mine sump with dim light and limited visibility, it is difficult to achieve precise adjustment through manual control.

[0005] Especially when facing sumps with curved sections or narrowing sections (such as U-shaped structures), since the sludge collection mechanism is in an extended state, the gaps between its two sides and the sump side walls are relatively small. When the equipment turns or deflects, if the hydraulic rod fails to retract in time, the sludge collection mechanism may collide with the sump side walls. Due to the lack of an effective buffer function in the design of the hydraulic rod, this kind of collision may cause the sludge collection mechanism to bear a large impact force, thus leading to problems such as damage or even failure, seriously affecting the cleaning efficiency and the operation reliability of the equipment. Summary of the Invention

[0006] The object of the present invention is to provide an efficient coal sump cleaning device for mine use to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, an efficient coal sump cleaning device for mine use is provided, including a sludge collecting mechanism arranged in front of the traveling mechanism and a sludge pumping mechanism arranged above the traveling mechanism. Among them, the sludge collecting mechanism is a telescopic structure with the telescopic direction towards the side wall of the sump. A sludge collecting bin is arranged on one side of the sludge collecting mechanism close to the traveling mechanism. The sludge collecting bin is communicated with the sludge collecting mechanism, so that the sludge collecting mechanism transfers the coal sludge into the sludge collecting bin. A telescopic driving mechanism is arranged in the sludge collecting bin, and the telescopic driving mechanism controls the telescopic state of the sludge collecting mechanism through the weight of the coal sludge in the sludge collecting bin;

[0008] The cleaning device further includes a sludge pumping mechanism for pumping out the excess coal sludge in the sludge collecting bin.

[0009] As a further improvement of this technical solution, the sludge pumping mechanism is a sludge pump installed on the traveling mechanism. The sludge suction port of the sludge pump is connected to a sludge suction pipe, and the sludge discharge port is connected to a sludge discharge pipe; among them,

[0010] One end of the sludge suction pipe extends into the sludge collecting bin.

[0011] As a further improvement of this technical solution, the sludge collecting mechanism includes an outer bucket and an inner bucket, both of which are semi-circular structures;

[0012] Both ends of the outer bucket are in a through state;

[0013] One end of the inner bucket is in a through state, and the other end is in a closed state. The outer circle of the inner bucket fits with the inner circle of the outer bucket, so that the inner bucket realizes sliding at both ends of the outer bucket through a sliding member.

[0014] As a further improvement of this technical solution, a first rotating shaft in the same direction as the outer bucket is rotatably arranged in the outer bucket. First spiral plates are arranged opposite to both ends of the first rotating shaft. A sludge discharge port is arranged in the middle part of the top of the outer bucket, and a guiding mechanism is arranged between the two first spiral plates where the first rotating shaft is located. The guiding mechanism transfers the coal sludge guided by the first spiral plates into the sludge collecting bin through the sludge discharge port.

[0015] As a further improvement of this technical solution, a second rotating shaft is rotatably arranged in the inner bucket. One end of the second rotating shaft is rotatably connected to the closed end of the inner bucket, and the other end is provided with a connecting shaft that slides and inserts into the first rotating shaft. The connecting shaft is a polygonal structure;

[0016] A second spiral plate is further arranged on the outer circle of the second rotating shaft to guide the coal sludge towards the first spiral plate during the rotation of the second rotating shaft.

[0017] As a further improvement of the present technical solution, a baffle is provided on the outer ring of the outer bucket. The baffle is integrally in a U-shaped structure, and the open end of the baffle is fixedly provided on the outer ring of the outer bucket and is located at the mud discharge port;

[0018] The inner wall of the baffle and the outer ring of the mud collecting mechanism jointly enclose a mud collecting bin, and the mud collecting bin communicates with the mud discharge port.

[0019] As a further improvement of the present technical solution, the telescopic driving mechanism includes a bearing plate longitudinally slidably arranged in the mud collecting bin, and the end face of the bearing plate is attached to the inner wall of the baffle;

[0020] The bottom of the bearing plate is in an inclined state with a lower middle and higher ends;

[0021] The telescopic driving mechanism further includes transmission rods located on both sides of the baffle. One end of the transmission rod is fixedly connected to the end of the inner bucket, and the other end laterally slides through the baffle and abuts against the inclined surface of the bearing plate. A return spring for elastically connecting the two is provided between the baffle and the outer ring of the transmission rod.

[0022] As a further improvement of the present technical solution, the material guiding mechanism includes a connecting belt with one end rotatably connected to the first rotating shaft and the other end rotatably connected to the third rotating shaft. The third rotating shaft is rotatably arranged on the side wall of the baffle; the connecting belt is located between the two first spiral plates and also penetrates through the mud discharge port. The top of the connecting belt inclines towards the top of the baffle, and a plurality of scraping plates are arranged on the outer ring of the connecting belt.

[0023] As a further improvement of the present technical solution, a flat plate is provided on the inner wall of the outer bucket, and the top end of the flat plate extends above the bearing plate.

[0024] As a further improvement of the present technical solution, a mud blocking rod is provided on the side of the mud suction pipe facing the scraping plate. One end of the mud blocking rod penetrates into the mud suction pipe, and a first magnet block is provided at the other end;

[0025] Among the plurality of scraping plates, a second magnet block is provided at the end of one scraping plate, and a third magnet block is provided at the end of another;

[0026] Among the second magnet block and the third magnet block, one is repelled by the first magnet block with the same polarity, and the other is attracted by the first magnet block with the opposite polarity, so that the scraping plate drives the mud blocking rod to reciprocate in the mud suction pipe during rotation, enabling the mud blocking rod to adjust the flow rate in the mud suction pipe and change the force-bearing state of the bearing plate.

[0027] Compared with the prior art, the beneficial effects of the present invention:

[0028] 1. In the efficient coal sump cleaning device for mines, a sludge collecting bin is established to temporarily collect the coal sludge, and the weight of the coal sludge is used to drive the telescopic movement of the sludge collecting mechanism. Moreover, since the driving force mainly acts through the inclined plane, the sludge collecting mechanism can be reset through the inclined plane when facing collisions, achieving buffering during the collision process. This not only avoids the impact intensity on the sludge collecting mechanism but also reduces the operation times of the staff.

[0029] 2. In the efficient coal sump cleaning device for mines, the position of the mud blocking rod is continuously adjusted through the second magnet block and the third magnet block, so that the sludge extraction volume of the sludge extraction pipe switches back and forth between increasing and decreasing, forcing the amount of coal sludge on the top of the bearing plate to continuously change, realizing the reciprocating movement of the second spiral plate, and enabling the second spiral plate to frequently approach the first spiral plate, thereby improving the efficiency of guiding the coal sludge on both sides to the middle.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0043] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more, unless otherwise specifically defined.

[0044] In the related art, a Chinese patent with the publication number CN115559376A discloses a coal mine sump cleaning robot applicable to multiple working conditions. This patent uses a hydraulic rod to adjust the length of the sludge collecting mechanism 100. Similarly, this patent also faces the above problems, that is, when facing a bending section or a narrowing section, since the hydraulic rod cannot automatically extend and retract, it is difficult for the hydraulic rod to buffer, so that when the sludge collecting mechanism 100 collides with the side wall of the sump, it is easily damaged by a large impact force.

[0045] Please refer to Figure 1 and Figure 3 As shown, a high-efficiency sump cleaning device for mine use is provided, including a sludge collecting mechanism 100 arranged in front of the traveling mechanism 300 and a sludge pumping mechanism arranged above the traveling mechanism 300. Among them, the sludge collecting mechanism 100 is a telescopic structure with the telescopic direction facing the side wall of the sump; a sludge collecting bin 200 is arranged on one side of the sludge collecting mechanism 100 close to the traveling mechanism 300, and the sludge collecting bin 200 is communicated with the sludge collecting mechanism 100, so that the sludge collecting mechanism 100 transfers the coal sludge into the sludge collecting bin 200. A telescopic driving mechanism 210 is arranged in the sludge collecting bin 200, and the telescopic driving mechanism 210 controls the telescopic state of the sludge collecting mechanism 100 through the weight of the coal sludge in the sludge collecting bin 200.

[0046] Moreover, since the coal sludge continuously enters the sludge collecting bin 200 through the sludge collecting mechanism 100, this will cause the sludge in the sludge collecting bin 200 to overflow. For this reason, the sump cleaning device further includes a sludge pumping mechanism for pumping out the excess coal sludge in the sludge collecting bin 200.

[0047] It should be understood that the sludge pumping mechanism can be subsequently connected to equipment such as a coal sludge rough separation device and a filter press system. Among them,

[0048] The coal sludge rough separation device includes:

[0049] Linear vibrating screen: As a pre-stage filtering device, it separates the coal sludge into thick and thin through vibration. The screen plate gap is relatively small, generally ≤1mm, which can effectively intercept large particle coal sludge and allow the fine coal sludge water to pass through;

[0050] Buffer water tank or buffer tank: It mainly plays a role of buffering and stirring between the vibrating screen and the filter press, can effectively prevent the precipitation of coal sludge particles, reduce the possibility of the filter press pump sucking air, convey coal sludge water with uniform density and easy to form to the filter press, and improve the filter press efficiency.

[0051] The filter press system includes:

[0052] High-efficiency plate and frame filter press: It is used for dehydrating the fine coal sludge water after rough separation, so that the coal sludge and water are completely separated. This machine adopts automatic plate pulling and an automatic integrated belt conveyor. After the coal sludge cake is horizontally sent out of the filter press by the conveyor, it naturally raises a certain height and can be directly loaded into a mine car and transported out;

[0053] Filter press feed pump: A highly wear-resistant slurry pump is used to pressurize and transport the fine coal slime water in the buffer water tank to the filter press for filtration, with a long service life.

[0054] It should be noted that the traveling mechanism 300 adopts a crawler chassis system, and the crawler can provide good grip performance for the traveling mechanism 300 to avoid slipping of the traveling mechanism 300 in the sump.

[0055] That is to say, by establishing the sludge collection bin 200 to temporarily collect the coal slime, the weight of the coal slime is used to drive the telescopic movement of the sludge collection mechanism 100. And since the driving force mainly acts through the inclined plane, the sludge collection mechanism 100 can be reset through the inclined plane when facing a collision, achieving buffering during the collision process. This not only avoids the impact intensity on the sludge collection mechanism 100 but also reduces the operation times of the staff.

[0056] The sludge pumping mechanism mainly consists of a sludge pump 301. As Figure 1 shown, the sludge pump 301 is installed on the traveling mechanism 300. The sludge suction port of the sludge pump 301 is connected to the sludge suction pipe 302, and the sludge discharge port is connected to the sludge discharge pipe 303. Among them, one end of the sludge suction pipe 302 extends into the sludge collection bin 200 and keeps a certain distance from the telescopic drive mechanism 210 to avoid pumping out all the coal slime on the top of the telescopic drive mechanism 210. The end of the sludge discharge pipe 303 is connected to the coal slime rough separation device mentioned above for subsequent operations.

[0057] As Figure 2 shown, the sludge collection mechanism 100 includes an outer bucket 110 and an inner bucket 111. Both the outer bucket 110 and the inner bucket 111 are semi-circular structures. However, the difference is that both ends of the outer bucket 110 are in a through state, while one end of the inner bucket 111 is in a through state and the other end is in a closed state. And the outer circle of the inner bucket 111 fits with the inner circle of the outer bucket 110, enabling the inner bucket 111 to slide at both ends of the outer bucket 110 through a sliding component. Or, the inner circle of the inner bucket 111 can be made to fit with the outer circle of the outer bucket 110, and then slide at both ends of the outer bucket 110 through a sliding component.

[0058] Among them, the sliding component can adopt the commonly used slide rails and chutes currently, that is, slide rails are set on the inner or outer circle of the inner bucket 111, and chutes are set on the outer or inner circle of the outer bucket 110. By inserting the slide rails into the chutes, the sliding connection between the outer bucket 110 and the inner bucket 111 can be achieved.

[0059] Next, a first rotating shaft 112 is rotatably arranged inside the outer bucket 110 in the same direction as the outer bucket 110. At both ends of the first rotating shaft 112, first spiral plates 113 are disposed opposite to each other. In this way, when the first rotating shaft 112 rotates, the first rotating shaft 112 can guide the slime to the middle part of the outer bucket 110 through the first spiral plates 113. Correspondingly, a sludge discharge port 117 is provided in the middle part of the top of the outer bucket 110, and a material guiding mechanism 400 is arranged between the two first spiral plates 113 of the first rotating shaft 112. The material guiding mechanism 400 transfers the slime guided by the first spiral plates 113 into the sludge collecting bin 200 through the sludge discharge port 117. Herein, the first rotating shaft 112 is driven by a motor 118. The motor 118 is arranged on the outer ring of the outer bucket 110. By arranging a chain between the motor 118 and the first rotating shaft 112, the power of the motor 118 is transmitted to the first rotating shaft 112 through the chain, causing the first rotating shaft 112 to rotate.

[0060] A second rotating shaft 114 is also rotatably arranged inside the inner bucket 111. One end of the second rotating shaft 114 is rotatably connected to the closed end of the inner bucket 111, and the other end is provided with a connecting shaft 116 that is slidably inserted into the first rotating shaft 112. The connecting shaft 116 has a polygonal structure, such as a hexagon, an octagon, etc. Such a design enables the first rotating shaft 112 to drive the second rotating shaft 114 to rotate synchronously when the first rotating shaft 112 rotates. Moreover, the second rotating shaft 114 is slidably connected to the first rotating shaft 112 through the connecting shaft 116, which does not affect the transmission of the second rotating shaft 114. At the same time, a second spiral plate 115 is arranged on the outer ring of the second rotating shaft 114 to guide the slime towards the first spiral plate 113 during the rotation of the second rotating shaft 114.

[0061] As Figure 3 and Figure 4 shown, the structure formed by the sludge collecting bin 200 is presented. From the Figure 3 top view in, the baffle 201 is integrally in a U-shaped structure, and the open end of the baffle 201 is fixedly arranged on the outer ring of the outer bucket 110 and is located at the sludge discharge port 117. At this time, the inner wall of the baffle 201 and the outer ring of the sludge collecting mechanism 100 jointly enclose to form the sludge collecting bin 200. And the sludge discharge port 117 is located at the sludge collecting bin 200, so the sludge collecting bin 200 is communicated with the sludge discharge port 117.

[0062] As Figure 4 shown, the telescopic driving mechanism 210 includes a bearing plate 211 that is longitudinally slidably arranged inside the sludge collecting bin 200, and the end face of the bearing plate 211 is attached to the inner wall of the baffle 201 to prevent the slime from falling downward through the gap between the bearing plate 211 and the baffle 201. As Figure 5As shown, the bottom of the bearing plate 211 is in an inclined state with the middle low and both ends high. At the same time, the telescopic driving mechanism 210 further includes transmission rods 212 located on both sides of the baffle 201. One end of the transmission rod 212 is fixedly connected to the end of the inner bucket 111. After the other end slides horizontally through the baffle 201, it abuts against the inclined surface of the bearing plate 211. A return spring 213 that elastically connects the two is provided between the baffle 201 and the outer ring of the transmission rod 212. In this way, when the bearing plate 211 moves downward, the bearing plate 211 can drive the inner bucket 111 to extend through the transmission rod 212.

[0063] Moreover, to reduce the friction between the inclined surface of the bearing plate 211 and the end of the transmission rod 212, a rotating wheel is provided at the end of the transmission rod 212 in the present invention, and the rotating wheel is rotatably connected to the transmission rod 212.

[0064] It should be noted that since the outer ring of the outer bucket 110 is in an arc shape, a gap will be generated between the bearing plate 211 and the outer ring of the outer bucket 110 during the downward movement of the bearing plate 211. For this reason, the present invention performs leveling treatment on the part of the outer ring of the outer bucket 110 corresponding to the sliding path of the bearing plate 211. That is, the part of the outer ring of the outer bucket 110 corresponding to the sliding path of the bearing plate 211 is set as a plane ( Figure 4 the shape filled on the left side of the bearing plate 211 in the figure). At this time, when the bearing plate 211 moves downward under the weight of the slime, there will be no gaps at the four end faces of the bearing plate 211.

[0065] Working principle:

[0066] When the inner bucket 111 does not extend, the motor 118 drives the first rotating shaft 112 to rotate through the chain. The first rotating shaft 112 drives the second rotating shaft 114 to rotate through the connecting shaft 116. The second rotating shaft 114 drives the second spiral plate 115 to rotate. The second spiral plate 115 rotates and guides the slime to the first spiral plate 113 through the spiral surface. The first spiral plate 113 guides the slime to the feeding mechanism 400. The feeding mechanism 400 transfers the slime to the top of the bearing plate 211 through the sludge discharge port 117. At this time, the weight of the slime is applied to the top of the bearing plate 211, causing the bearing plate 211 to move downward under force. The bearing plate 211 drives the transmission rod 212 to move towards the inner bucket 111 through the inclined surface. At this time, the inner bucket 111 extends. The specific state is as Figure 6 shown, the second rotating shaft 114 can still rotate synchronously with the first rotating shaft 112 through the connecting shaft 116.

[0067] When the inner bucket 111 collides with the side wall of the sump, the inner bucket 111 will receive a reaction force moving towards the outer bucket 110. At this time, the outer bucket 110 will drive the transmission rod 212 to move towards the bearing plate 211. The movement of the transmission rod 212 will push the bearing plate 211 upward through the inclined surface of the bearing plate 211, thereby realizing the retraction of the inner bucket 111. After the collision ends, the bearing plate 211 can still drive the inner bucket 111 to continue to extend through the slime at the top.

[0068] Moreover, when the height of the slime is higher than the bottom height of the sludge suction pipe 302, the sludge pump 301 sucks the slime through the sludge suction pipe 302 and then discharges it to the next process through the sludge discharge pipe 303.

[0069] As Figure 7 and Figure 8 shown, the material guiding mechanism 400 includes a connecting belt 412 with one end rotatably connected to the first rotating shaft 112 and the other end rotatably connected to a third rotating shaft 410. The third rotating shaft 410 is rotatably arranged on the side wall of the baffle 201; the connecting belt 412 is located between two first spiral plates 113, and at the same time, it also passes through the sludge discharge port 117. Moreover, the top of the connecting belt 412 inclines towards the top of the baffle 201, and a plurality of scraping plates 413 are arranged on the outer ring of the connecting belt 412. In addition, in order to ensure the sludge scraping efficiency, a flat plate 414 is arranged on the inner wall of the outer bucket 110, and the top end of the flat plate 414 extends above the bearing plate 211.

[0070] Furthermore, turntables 411 can be arranged on the outer rings of both the first rotating shaft 112 and the third rotating shaft 410. The turntables 411 are sleeved on the outer rings of the turntables 411. By means of the turntables 411, the overall thickness of the connecting belt 412 is increased, so that the scraping plates 413 can be closer to the flat plate 414, and the end parts of the scraping plates 413 are attached to the surface of the flat plate 414.

[0071] In this way, when the first rotating shaft 112 rotates, the first rotating shaft 112 drives the connecting belt 412 to rotate through the turntable 411. The rotation of the connecting belt 412 drives the scraping plates 413 to move. The movement of the scraping plates 413 scrapes the slime towards the flat plate 414. When the slime is at the top of the flat plate 414, the scraping plates 413 scrape the slime into the sludge collecting bin 200, causing the slime to fall on the top of the bearing plate 211.

[0072] Not only that, in some embodiments, such as Figure 9As shown in the figure, a mud baffle rod 310 is provided on one side of the mud suction pipe 302 facing the scraper 413. One end of the mud baffle rod 310 slides into the mud suction pipe 302, and a first magnet block 311 is provided at the other end. Among the multiple scrapers 413, a second magnet block 320 is provided at the end of one scraper 413, and a third magnet block 321 is provided at the end of another scraper 413. Among the second magnet block 320 and the third magnet block 321, one is repelled by the first magnet block 311 with the same polarity, and the other is attracted by the first magnet block 311 with the opposite polarity, so that during the rotation of the scraper 413, the second magnet block 320 and the third magnet block 321 drive the mud baffle rod 310 to reciprocate in the mud suction pipe 302, enabling the mud baffle rod 310 to adjust the flow rate in the mud suction pipe 302 and change the stress state of the bearing plate 211.

[0073] Working principle:

[0074] Assume that the second magnet block 320 is attracted by the first magnet block 311 with the opposite polarity, and the third magnet block 321 is repelled by the first magnet block 311 with the same polarity. When the second magnet block 320 rotates to the vicinity of the first magnet block 311, the second magnet block 320 attracts the first magnet block 311. At this time, the first magnet block 311 drives the mud baffle rod 310 to approach the second magnet block 320. Most of the mud baffle rod 310 is outside the mud suction pipe 302. At this time, the mud suction volume of the mud suction pipe 302 is in the maximum state, and the silt on the top of the bearing plate 211 can be quickly sucked away, enabling the bearing plate 211 to be reset upward elastically through the reset spring 213. When the third magnet block 321 rotates to the vicinity of the first magnet block 311, the third magnet block 321 pushes the first magnet block 311 towards the mud suction pipe 302. At this time, the first magnet block 311 drives the mud baffle rod 310 to extend into the mud suction pipe 302, occupying the space in the mud suction pipe 302. At this time, the mud suction volume of the mud suction pipe 302 decreases, and the silt on the top of the bearing plate 211 gradually increases, causing the bearing plate 211 to move downward under the gravity of the silt. In this way, the bearing plate 211 can achieve reciprocating motion, and further enable the inner bucket 111 to also perform reciprocating motion. The reciprocating motion of the inner bucket 111 can cause the second spiral plate 115 to frequently approach the first spiral plate 113, thereby improving the efficiency of guiding the coal slime on both sides to the middle.

[0075] In summary, by continuously adjusting the position of the mud baffle rod 310 through the second magnet block 320 and the third magnet block 321, the mud suction volume of the mud suction pipe 302 can be switched back and forth between increasing and decreasing, forcing the amount of coal slime on the top of the bearing plate 211 to continuously change, realizing the reciprocating motion of the second spiral plate 115, enabling the second spiral plate 115 to frequently approach the first spiral plate 113, and improving the efficiency of guiding the coal slime on both sides to the middle.

[0076] It should be noted that the distance between the bottom end of the sludge suction pipe 302 and the top of the bearing plate 211 can be adjusted according to the actual environment, and the present invention does not make any limitations in this regard.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present invention, and are not used to limit the present invention.

The scope of the present invention claimed is defined by the appended claims and their equivalents.
