Description

Technical Field

[0001] The present invention relates to the technical field of electric power equipment, and in particular to a wire connection device and a wire connection method. Background Art

[0002] During power line transmission, wire damage usually occurs at the connection between two wires or in the middle of a wire due to some environmental and human factors.

[0003] Damage to the wire will increase the resistance of the wire at the damaged part. When the resistance increases, it will cause the line to heat up. Continuous heating may cause the temperature of the wire to rise to a dangerous level, which will cause the insulation layer of the wire to soften or even melt further, and lose its protective effect on the wire. In this case, the metal part of the wire is more susceptible to external factors, accelerating aging and damage. The wire may melt and break, which directly affects the transmission performance of the line, causing power transmission fluctuations, affecting the safe and stable operation of the entire power system, and may even cause the wire line to break, causing power outages in large areas. In the prior art, other wires are usually used to crimp and connect the two ends of the damaged part of the wire. The wire connection at the crimping point is unstable, and heat will still occur at the crimping point, resulting in instability in power transmission. Summary of the invention

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0057] like Figure 1As shown, this embodiment provides a wire connection device 10, including a connection component 1, a resistance adjustment component 4 and two conduction components 2, wherein the resistance adjustment component 4 is arranged on the connection component 1, the resistance adjustment component 4 is connected in series with the connection component 1, the resistance adjustment component 4 is configured to adjust the resistance of the connection component 1, and the two conduction components 2 are electrically connected to the two ends of the connection component 1, one of the conduction components 2 is used to connect and conduct with the first end of the wire segment to be reinforced, and the other conduction component 2 is used to connect and conduct with the second end of the wire segment to be reinforced. By respectively arranging the conduction components 2 at the first end and the second end of the wire segment to be reinforced, and the two conduction components 2 are electrically connected to the two ends of the connection component 1, an electric circuit is connected in parallel at the two ends of the wire segment to be reinforced, so that when the current flows, it does not pass through the wire segment to be reinforced, but flows through the wire connection device 10 to achieve the connection of the two ends of the wire segment to be reinforced, so as to avoid the wire segment to be reinforced The continuous heating due to poor contact at the wire segment to be reinforced, thereby causing the wire strands to be broken or even the wire line to be broken, and ensure the stability and safety of power transmission. In addition, a resistance adjusting component 4 is provided in the connecting component 1, and the resistance adjusting component 4 is connected in series with the connecting component 1. When the wire connecting device 10 is connected in parallel to the two ends of the wire segment to be reinforced, the resistance adjusting component 4 can adjust the resistance of the entire wire connecting device 10 by adjusting the resistance of the connecting component 1, so that the resistance of the wire connecting device 10 is the same as the resistance of the wire segment to be reinforced, which helps to maintain the transmission efficiency in the entire circuit, enhance the adaptability of the wire connecting device 10, maintain the normal operation of the circuit, and reduce the loss of the circuit during transmission.

[0058] Alternatively, if Figure 2 As shown, in this embodiment, the conducting component 2 is electrically connected to the connecting component 1 through the fixing member 15, and the conducting component 2 is detachably connected to the connecting component 1 through the fixing member 15, and the adaptability to wires of different specifications can be improved by replacing the conducting component 2. It should be noted that the fixing member 15 is a bolt, and in other embodiments, it can also be connected by a pin shaft or a clamping method, as long as the conducting component 2 and the connecting component 1 can be detachably electrically connected.

[0059] Furthermore, if Figure 1-Figure 3As shown, the conducting component 2 includes two movable conducting members 22 and a locking member 23. The first ends of the two movable conducting members 22 are rotatably connected. The two movable conducting members 22 are jointly sleeved on the periphery of the conductor segment to be reinforced and are electrically connected to the conductor segment to be reinforced. At least one movable conducting member 22 is connected and conductive to the end of the connecting component 1. The locking member 23 is configured to lock the second ends of the two movable conducting members 22, thereby ensuring that the stable transmission of current is ensured while the conductor segment to be reinforced is being reinforced. In addition, the movable conducting member 22 can adapt to conductor segments to be reinforced of different diameters within a certain range, and can be tightly sleeved on the conductor segment to be reinforced after adjusting its posture by rotation, thereby achieving good electrical connection. Optionally, in this embodiment, both movable conducting members 22 are connected and conductive to the end of the connecting component 1. In other embodiments, one movable conducting member 22 can also be connected and conductive to the end of the connecting component 1.

[0060] Alternatively, if Figure 3 As shown, in this embodiment, the conduction component 2 also includes a conduction connector 21, which is connected and conducted with the end of the connection component 1 through the fixing member 15. The conduction connector 21 includes a connecting plate and two rotating pins 211, and the two ends of the conduction connector 21 are provided with rotating pins 211. The first ends of the two movable conduction components 22 are respectively rotatably connected to the two rotating pins 211, so that the movable conduction components 22 can rotate around the corresponding rotating pins 211, thereby realizing a more flexible conduction function. It should be noted that the conduction connector 21 includes two connecting plates, one of which is located at the lower end of the movable conduction component 22, and the connecting plate located at the lower end of the movable conduction component 22 is connected and conducted with the end of the connection component 1 through the fixing member 15, and the other connecting plate is located at the upper end of the movable conduction component 22, the first end of the rotating pin 211 is fixedly connected to one of the connecting plates, and the second end of the rotating pin 211 passes through the corresponding movable conduction component 22 and is fixedly connected to the other connecting plate to ensure the reliability of the connection. In other embodiments, the number of connecting plates may also be one.

[0061] Alternatively, if Figure 3As shown, in this embodiment, the conduction component 2 is in the form of a clamp, and the two movable conduction members 22 are both semicircular clamp rings. Optionally, in this embodiment, the locking member 23 is a butterfly bolt, and the butterfly bolt includes a threaded bolt and a butterfly nut, wherein the second end of one semicircular clamp ring is rotatably connected with a bolt, and the second end of the other semicircular clamp ring is provided with a U-shaped groove, the shape of the U-shaped groove is adapted to the bolt, and the bolt can be clamped in the U-shaped groove. When the two semicircular clamp rings are clamped, the bolt is clamped in the U-shaped groove, and then the butterfly nut is screwed at the end of the bolt extending out of the U-shaped groove, so that the two clamp rings are tightly connected to the wire segment to be reinforced. The clamp can provide stable conduction performance, and the clamp contacts the wire segment to be reinforced through a large contact area, which can effectively reduce the contact resistance and reduce the problems of heating or sparking caused by poor contact. In other embodiments, the conduction component 2 can also be set as a clamp or a tension clamp, etc., which can achieve the connection support of the wire segment to be reinforced.

[0062] Alternatively, if Figure 4 As shown, in this embodiment, the movable conductive member 22 includes an insulating layer 221, a conductive layer 222 and a plurality of conductive buffers 223, wherein the insulating layer 221 is wrapped around the outer periphery of the conductive layer 222, and a plurality of conductive buffers 223 are arranged at intervals on the inner peripheral wall of the conductive layer 222, and the conductive buffers 223 are in contact with the wire segment to be reinforced. By providing the insulating layer 221, the outer periphery of the movable conductive member 22 is electrically insulated, thereby ensuring the safety of the operator. In addition, by arranging a plurality of conductive buffers 223 at intervals on the inner peripheral wall of the conductive layer 222, the conductive buffers 223 can be attached to the surface of the wire segment to be reinforced when the conductive component 2 is sleeved on the wire segment to be reinforced, which can increase the friction with the wire segment to be reinforced, improve the connection stability of the conductive component 2, and provide good electrical contact. It should be noted that in this embodiment, the conductive buffer 223 is a conductive rubber, which not only has certain conductive properties, but also has good elasticity. Since the conductive rubber is a prior art, it will not be described here. Optionally, in this embodiment, the conductive buffer 223 has a sawtooth shape. In other implementations, it may also have a wavy shape or a trapezoidal shape, which is not limited here.

[0063] Furthermore, if Figure 1 and Figure 5As shown, the resistance adjustment component 4 includes a resistance adjustment module 41, a current measurement module 42 and a control module 43, wherein the resistance adjustment module 41 is arranged in the connection component 1 and is connected in series with the connection component 1, the current measurement module 42 is electrically connected to the resistance adjustment module 41, and is used to detect the current of the conductor segment to be reinforced, the resistance adjustment module 41 and the current measurement module 42 are both electrically connected to the control module 43, and the control module 43 can adjust the resistance value of the resistance adjustment module 41 according to the detection value of the current measurement module 42. When the wire connecting device 10 is connected in parallel to the two ends of the wire segment to be reinforced, the resistance adjustment component 4 starts to operate, and the current measuring module 42 detects the current in the wire segment to be reinforced in real time. The current measuring module 42 converts the detected current value into a suitable electrical signal and sends it to the control module 43. After receiving the electrical signal corresponding to the current value, the control module 43 compares it with the preset target current value. If the detected current value is greater than the target current value, it means that the resistance of the wire connecting device 10 may be too small, and the control module 43 will send an instruction to the resistance adjustment module 41 to increase the resistance value of the resistance adjustment module 41. If the detected current value is less than the target current value, it means that the resistance of the wire connecting device 10 may be too large, and the control module 43 will send an instruction to the resistance adjustment module 41 to reduce the resistance value of the resistance adjustment module 41 to ensure that the resistance value of the wire connecting device 10 is the same as the resistance value of the wire segment to be reinforced, thereby improving the adaptability of the wire connecting device 10 to different wire segments to be reinforced and ensuring the normal operation of the wire connecting device 10. It should be noted that, in this embodiment, the resistance adjustment module 41 is a variable high-voltage resistor, the current measurement module 42 is a Hall sensor, and the control module 43 is a circuit board. Since the connection relationship between the variable high-voltage resistor, the Hall sensor and the circuit board is the existing technology, it will not be repeated.

[0064] Optionally, in this embodiment, the resistance adjustment component 4 further includes a communication module 44, which is electrically connected to the control module 43. The communication module 44 can obtain the operation status of the resistance adjustment component 4 in real time, thereby accurately monitoring and repairing the resistance adjustment component 4, thereby enhancing the operability and monitorability of the resistance adjustment component 4. It should be noted that the type of the communication module 44 is not limited, and it only needs to be able to realize the communication between the resistance adjustment component 4 and the remote.

[0065] Furthermore, if Figure 1 As shown, the wire connection device 10 further includes two clamping components 3, which are arranged at intervals and are both connected to the connection component 1, wherein one clamping component 3 is clamped at the first end of the wire segment to be reinforced, and the other clamping component 3 is clamped at the second end of the wire segment to be reinforced. By providing two clamping components 3, both ends of the wire segment to be reinforced are reliably fixed, thereby ensuring the connection stability of the wire segment to be reinforced.

[0066] Optionally, in this embodiment, two clamping components 3 are disposed between two conductive components 2, and the interval between each clamping component 3 and the conductive component 2 on the same side is the same, which can ensure that the forces on both ends of the conductor to be reinforced are the same. In other embodiments, the positions of the clamping components 3 are not limited, and they can be disposed on the outside of the two conductive components 2 at the same time, or one clamping component 3 is disposed on the inside of the two conductive components 2, and one clamping component 3 is disposed on the outside of the two conductive components 2.

[0067] Furthermore, if Figure 6 As shown, the clamping assembly 3 includes an inner ring 31 and an outer ring 32, wherein the inner ring 31 is clamped and fixed to the outer circumference of the conductor segment to be reinforced, the outer ring 32 surrounds the outside of the inner ring 31, the outer ring 32 is fixedly connected to the connecting assembly 1, and the conductor segment to be reinforced can drive the inner ring 31 to rotate relative to the outer ring 32 along the circumferential direction of the inner ring 31 by a preset angle γ. The inner ring 31 can be clamped and fixed on the outer circumference of the wire segment to be reinforced, and fits tightly with the wire segment to be reinforced, so as to ensure that in subsequent operation or use, the inner ring 31 can rotate with the twisting movement of the wire segment to be reinforced, forming a relatively fixed relationship between the two ends of the wire segment to be reinforced. It can be regarded as that the two ends of the wire segment to be reinforced are clamped by the inner ring 31 to form a complete wire with the free end of the wire again. The outer ring 32 surrounds the outside of the inner ring 31, and the outer ring 32 is firmly fixed to the connection component 1. The stability of the connection enables the entire structure to remain stable when subjected to external force or in a working state. When the wire segment to be reinforced is twisted due to external force, the inner ring 31 can be driven to rotate relative to the outer ring 32 along the circumferential direction of the inner ring 31 by a preset angle γ. During the twisting process of the wire, if the wire segment to be reinforced is twisted in the same direction, it will not affect the connection of the wire segment to be reinforced. If the wire segment to be reinforced is twisted in different directions, it can also prevent the wire segment to be reinforced from twisting too much. Prevent the wire from fatigue during repeated twisting, which may lead to wire breakage or even fracture.

[0068] It should be noted that the preset angle γ is 3°-10°, which can be 3°, 4°, 5°, 6°, 7°, 8°, 9° or 10°. In the present embodiment, it is preferably 6°, which can prevent the torsion dispersion of the wires at both ends of the clamping assembly 3 from occurring due to excessive torsion angle when the wire segment to be reinforced is twisted, thereby causing the wire resistance to change.

[0069] Alternatively, if Figure 6 and Figure 7As shown, in this embodiment, the inner ring 31 is set to an open ring shape, and the inner ring 31 has a certain elasticity. Inner ring fixing holes 311 are set at both ends of the inner ring 31. The bolt passes through one of the inner ring fixing holes 311 and is threadedly connected with the other inner ring fixing hole 311, so as to ensure that the inner ring 31 clamps and fixes the wire segment to be reinforced. The above-mentioned setting makes the structure of the inner ring 31 integrated, and it is more convenient to adjust the position of the clamping component 3, and the operation is convenient and efficient, thereby improving the work efficiency of the entire clamping process, and can better ensure the clamping effect and quality, and reduce the errors or safety hazards that may be caused by inconvenient operation. In other embodiments, the structure of the inner ring 31 is not limited, and it can be two half circles or three arc circles, etc., which can meet the requirements of clamping the wire segment to be reinforced.

[0070] Optionally, in this embodiment, the inner ring 31 is further provided with protrusions, which are arranged at intervals on the inner circumferential wall of the inner ring 31, and the protrusions can increase the friction between the inner ring 31 and the conductor segment to be reinforced. It should be noted that the shape of the protrusion is triangular, and in other embodiments, the shape of the protrusion is not limited, and can be arc-shaped, trapezoidal or wavy.

[0071] Optionally, in this embodiment, the outer ring 32 includes a first half ring 321 and a second half ring 322, and hinge pins 325 are provided through the ends of the first half ring 321 and the second half ring 322. The first half ring 321 and the second half ring 322 can rotate around the hinge pin 325. The ends of the first half ring 321 and the ends of the second half ring 322 are both provided with first fixing holes 323. Bolts pass through the first fixing holes 323 of the first half ring 321 and are threadedly connected with the first fixing holes 323 of the second half ring 322, thereby ensuring that the outer ring 32 can be tightly surrounded by the inner ring 31, and at the same time, the inner ring 31 can rotate within the outer ring 32 within a limited position. When clamping the wire of the segment to be reinforced, the wire of the segment to be reinforced is passed through the opening of the inner ring 31, so that the inner ring 31 is sleeved on the wire of the segment to be reinforced, and the inner ring 31 is fastened by bolts and the inner ring fixing hole 311, and the first half ring 321 and the second half ring 322 are rotated and opened relative to the hinge pin 325, and then the first half ring 321 and the second half ring 322 are buckled to form an outer ring 32 surrounding the inner ring 31, and the outer ring 32 is fastened by bolts and the first fixing hole 323, and finally the outer ring 32 is welded and fixed to the connection component 1. In order to fix the two ends of the wire of the segment to be reinforced. In other embodiments, the form of the outer ring 32 is not limited, and it can also be an open ring, etc., so that the inner ring 31 can be limitedly rotated inside the outer ring 32 while the outer ring 32 is fixed to the connection component 1.

[0072] Optionally, in this embodiment, both the inner ring 31 and the outer ring 32 are made of insulating materials. The provision of the insulating materials enables the wire connecting device 10 to be connected to both ends of the wire segment to be reinforced, so that the two ends of the wire segment to be reinforced can only be conducted through the conducting component 2 and the connecting component 1 to form a conductive path, thereby preventing the wire connecting device 10 from forming an internal path when connected to the wire segment to be reinforced, thereby causing a wire short circuit. In other embodiments, one of the inner ring 31 and the outer ring 32 is made of insulating material, which can ensure that the wire connecting device 10 does not form an internal path when connected to the wire segment to be reinforced.

[0073] Alternatively, if Figure 7 and Figure 8 As shown, in this embodiment, the outer peripheral wall of the inner ring 31 is provided with a slot 312, and the inner peripheral wall of the outer ring 32 is provided with a key 324, and the key 324 can rotate relative to the slot 312 along the circumferential direction of the inner ring 31 by a preset angle γ. When the key 324 rotates in the slot 312, the shape and size of the slot 312 limit the movement range of the key 324, preventing excessive rotation between the inner ring 31 and the outer ring 32, thereby ensuring the stability and reliability of the entire clamping assembly 3. In other embodiments, the outer peripheral wall of the inner ring 31 may be provided with a key 324, and the inner peripheral wall of the outer ring 32 may be provided with a slot 312.

[0074] Alternatively, if Figure 8 As shown, the end face of the key 324 abuts against the end face of the slot 312, and the abutting end faces are arranged in an arc shape. The arc-shaped abutting surface can ensure that the key 324 can fit in the slot 312 and slide along the circumferential direction of the inner ring 31. The setting of the arc surface is adapted to the circumferential sliding direction, which can ensure that the key 324 slides more smoothly relative to the slot 312 and has a certain guiding effect. At the same time, the friction between the arc surfaces is relatively small, which helps to improve assembly efficiency, reduce assembly difficulty, and reduce possible wear on intermediate components during assembly.

[0075] Alternatively, if Figure 7 As shown, in this embodiment, there are four slots 312 and four keys 324, which are evenly distributed along the circumferential direction of the inner ring 31, so that when the clamping assembly 3 is twisted, the four evenly distributed slots 312 and the keys 324 cooperate with each other, which can effectively disperse the stress, thereby enhancing the anti-twisting ability of the entire structure and ensuring the integrity and reliability of the structure. In other embodiments, there is at least one slot 312 and one key 324, which can be two, three or five, etc., which are not limited here.

[0076] Furthermore, if Figure 1 and Fig. 9As shown, the connection component 1 includes a sleeve 11 and two connecting rods 12, wherein the sleeve 11 is provided with a resistance adjustment component 4, and the two connecting rods 12 are respectively located at the two ends of the sleeve 11, and the first end of the connecting rod 12 is slidably inserted into the sleeve 11 and is in conduction with the sleeve 11, and the second end of the connecting rod 12 is connected to and in conduction with the conduction component 2. The two connecting rods 12 are respectively located at the two ends of the sleeve 11, so that a symmetrical structure is formed between the sleeve 11 and the connecting rod 12, and the first end of the connecting rod 12 is slidably inserted into the sleeve 11 and is in conduction with the sleeve 11. This arrangement, on the one hand, allows the connection between the connecting rod 12 and the sleeve 11 to be adjusted according to the length of the wire segment to be reinforced, and on the other hand, the characteristic that the sleeve 11 and the connecting rod 12 can be in conduction ensures that the two ends of the wire segment to be reinforced can be smoothly conducted through the connection relationship between the sleeve 11 and the connecting rod 12, thereby ensuring the connectivity of the entire circuit system. At the same time, the second end of the connecting rod 12 is connected to and in conduction with the conduction component 2, further strengthening the continuity of the electrical connection of the entire system. It should be noted that if Fig.10 As shown, the inner layer of the sleeve 11 is a sleeve conductive layer 113, and the outer layer is a sleeve insulating layer 114. The sleeve insulating layer 114 is wrapped around the outer side of the sleeve conductive layer 113. The above arrangement enables the sleeve 11 to realize the conductive function while preventing the operator from touching the conductive part and causing danger. It should be noted that the sleeve conductive layer 113 and the connecting rod 12 can be made of high-strength metal materials, such as stainless steel or aluminum alloy, etc. In this embodiment, stainless steel is preferably used to ensure that the entire structure will not be deformed or damaged when subjected to a certain external force.

[0077] Alternatively, if Fig. 9 As shown, in this embodiment, the connection component 1 is further provided with an elastic member 13, which is always in a compressed state. The elastic member 13 is sleeved on the connection rod 12, and the first end of the elastic member 13 abuts against the end surface of the conduction component 2, and the second end of the elastic member 13 abuts against the end surface of the sleeve 11. The setting of the elastic member 13 enables a certain force to exist between the sleeve 11 and the conduction component 2 when the connection rod 12 adjusts its position relative to the sleeve 11, so that the adjustment of the conduction component 2 and the sleeve 11 has a buffering effect. It should be noted that the elastic member 13 is a spring, and in other embodiments, the type of the elastic member 13 is not limited.

[0078] Furthermore, if Figure 3 , Fig. 9 and Fig.11As shown, a slide groove 111 is provided on the side wall of the sleeve 11, and the slide groove 111 extends along the axial direction of the sleeve 11. A plurality of positioning grooves 112 are provided on the side wall of the sleeve 11 along the extension direction of the slide groove 111. Each positioning groove 112 is connected to the slide groove 111. A positioning pin 122 is provided at the first end of the connecting rod 12. The positioning pin 122 can slide along the slide groove 111, and the positioning pin 122 can selectively engage with any one of the positioning grooves 112. When the relative position of the sleeve 11 and the connecting rod 12 needs to be adjusted, the connecting rod 12 is rotated so that the positioning pin 122 escapes from the original positioning groove 112 and enters the slide groove 111, thereby adjusting the relative position of the sleeve 11 and the connecting rod 12. After the position adjustment is completed, the connecting rod 12 is rotated in the opposite direction so that the positioning pin 122 is again engaged in another positioning groove 112. During the sliding process, due to the guiding effect of the slide groove 111, the positioning pin 122 can move more accurately, and the positioning pin 122 can selectively engage with any one of the positioning grooves 112. When the positioning pin 122 is engaged with the positioning groove 112, the connecting rod 12 and the sleeve 11 can be engaged and fixed at a specific position. By adjusting the engaging position of the positioning pin 122 in different positioning grooves 112, the extending length of the connecting rod 12 relative to the sleeve 11 can be changed, thereby adjusting the length of the wire connecting device 10.

[0079] Optionally, in this embodiment, the locating pin 122 is insulated, and an insulating coating can be applied to the locating pin 122 or the locating pin 122 can be set as an insulating material. In this embodiment, it is preferred to apply an insulating coating to the locating pin 122, which can ensure the integrity of the connecting rod 12 and the safety of the operator.

[0080] Furthermore, if Fig. 9 As shown, the connection assembly 1 also includes a fastener 14. After the relative positions of the sleeve 11 and the connecting rod 12 are adjusted, the fastener 14 is threadedly connected to the portion of the positioning pin 122 that extends out of the positioning groove 112, and the fastener 14 abuts against the outer peripheral wall of the sleeve 11. The fastener 14 abuts against the side wall of the sleeve 11, which can provide additional stability and support for the entire connection assembly 1. By abutting against the outer peripheral wall of the sleeve 11, the fastener 14 can prevent the sleeve 11 and the connecting rod 12 from rotating relative to each other when subjected to external force, causing the connecting rod 12 to slip out of the sleeve 11, thereby destroying the connection function of the wire connecting device 10 on the wire segment to be reinforced. It should be noted that the fastener 14 is a nut.

[0081] Alternatively, if Fig.10As shown, in the present embodiment, the side wall of the sleeve 11 having the slide groove 111 is also provided with an abutment plane 115 along the extension direction of the slide groove 111, and the abutment plane 115 can abut against the fastener 14. When the fastener 14 contacts the abutment plane 115, due to the flatness of the abutment plane 115, the firmness of the fastener 14 can be better ensured.

[0082] like Fig.12 As shown, this embodiment also provides a wire connection method, using the above-mentioned wire connection device 10, the wire connection method specifically includes the following steps:

[0083] S1, fix and connect one of the conducting components 2 to the first end of the conductor segment to be reinforced, and fix and connect the other conducting component 2 to the second end of the conductor segment to be reinforced;

[0084] S2, adjusting the resistance value of the resistance adjustment component 4.

[0085] The wire connection method uses the above-mentioned wire connection device 10 to achieve the connection of the wire section to be reinforced, ensure the stability and safety of power transmission, and at the same time, when the wire connection device 10 is connected to the wire section to be reinforced, the wire connection device 10 can adjust the resistance value of its internal resistance adjustment component 4, thereby enhancing the adaptability of the wire connection device 10.

[0086] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
