Description

Technical Field

[0001] This invention relates to the field of grounding equipment technology, and more specifically, to a grounding device. Background Technology

[0002] When working on electrical equipment, safety measures such as power outage, voltage testing, and grounding should be implemented. Currently, the installation and removal of grounding wires in substations are all done manually. When installing or removing 220kV grounding wires, workers standing on insulated ladders cannot use the "high-hanging, low-use" method for their safety belts, as this poses a high risk of falls from heights. A grounding clamp lifting and traction device can be used to move the grounding clamp, avoiding the need for workers to climb before installing it.

[0003] In related technologies, the grounding clamp lifting and traction device includes a pole, a grounding clamp, a pulley, and a traction rope. The grounding clamp, pulley, and traction rope are all mounted on the pole. The traction rope works in conjunction with the pulley. When the operator pulls the traction rope, the pole can be raised, thereby enabling the grounding clamp to be attached to the conductor. Summary of the Invention

[0004] The main objective of this invention is to provide a grounding device to solve the problem of laborious operation when operators pull up the pole in related technologies.

[0005] To achieve the above objectives, the present invention provides a grounding device, comprising: a base; a hoisting mechanism disposed on the base and having a connecting cable, the free end of which can be connected to the device to be grounded, and the retraction and extension of the connecting cable can drive the base to rise and fall relative to the device to be grounded; a clamping structure movably connected to the base; a position adjusting structure connected between the base and the clamping structure, and capable of moving the clamping structure in both horizontal and vertical directions, so that the clamping structure can move to a position to clamp the lead wire of the device to be grounded; and a grounding wire, the first end of which is disposed on the clamping structure, and the second end of which is electrically connected to the ground.

[0006] Furthermore, the position adjustment structure includes a first adjustment rod and a second adjustment rod. The first adjustment rod is movably connected to the base along a first preset direction, and the second adjustment rod is movably disposed on the first adjustment rod along a second preset direction. The first adjustment rod extends along the second preset direction, and a clamping structure is disposed on the second adjustment rod. The first preset direction and the second preset direction are perpendicular to each other. One of the first preset direction and the second preset direction is a horizontal direction, and the other of the first preset direction and the second preset direction is a vertical direction.

[0007] Furthermore, the position adjustment structure also includes a first guide rod, a first driving member, and a mounting base. The first guide rod is disposed on the base and extends along a first preset direction. The first driving member and the mounting base are both disposed on the first guide rod. The first driving member drives the mounting base to move along the extension direction of the first guide rod. The first adjustment rod is disposed on the mounting base.

[0008] Furthermore, the position adjustment structure also includes a second driving member disposed on the second adjusting rod. The second driving member cooperates with the clamping structure to make the clamping structure rotate around a third preset direction. The first preset direction, the second preset direction, and the third preset direction are arranged perpendicularly to each other.

[0009] Furthermore, the clamping structure includes a mounting frame, a first clamping part, a second clamping part, and a third driving member. The first clamping part and the third driving member are both disposed on the mounting frame. The third driving member drives and cooperates with the second clamping part to move the second clamping part toward the top of the first clamping part.

[0010] Furthermore, the clamping structure also includes a connecting cylinder connected to the third driving member and a driving rod connected to the second clamping part. The connecting cylinder and the driving rod are driven together. The first end of the driving rod is inserted into the connecting cylinder. The cross-section of the first end of the driving rod is polygonal. The second end of the driving rod is connected to the second clamping part.

[0011] Furthermore, the first clamping part includes a clamping head, a connecting rod, and a second guide rod connected between the clamping head and the connecting rod. The second clamping part includes a clamping block and a guide groove disposed on the side of the clamping block. The second guide rod passes through the guide groove and is guided and engaged with the guide groove. The connecting rod is inserted into the side of the mounting frame near the second clamping part. The drive rod is threadedly engaged with the connecting rod.

[0012] Furthermore, the clamping block includes a first upright plate, a second upright plate, and a connecting plate connected between the first upright plate and the second upright plate. A guide groove is formed between the side of the first upright plate near the second guide rod and the side of the second upright plate near the second guide rod. The second end of the drive rod is connected to the side of the connecting plate away from the clamping head.

[0013] Furthermore, the grounding device also includes a limiting structure disposed on the substrate, with the middle part of the grounding wire passing through the limiting structure.

[0014] Furthermore, the limiting structure includes a connecting seat, a limiting plate, a limiting protrusion, and a limiting groove. The limiting plate is swayably mounted on the connecting seat. The connecting seat is provided with an accommodating space and a notch communicating with the accommodating space. The limiting protrusion is mounted on the limiting plate, and the limiting groove is mounted on the connecting seat and cooperates with the limiting protrusion for limiting. The middle part of the grounding wire enters into the accommodating space through the notch, and the limiting protrusion is connected to the notch.

[0015] According to the technical solution of this invention, a hoisting mechanism is provided on the base. The hoisting mechanism has a connecting cable, the free end of which is connected to the device to be grounded. When the connecting cable is retracted or extended, it can drive the base to rise or fall relative to the device to be grounded. A clamping structure is movably connected to the base. A position adjustment structure is connected between the base and the clamping structure. The position adjustment structure can drive the clamping structure to move in the horizontal and vertical directions, so that the clamping structure can move to the position to clamp the drain line of the device to be grounded. The first end of the grounding wire is set on the clamping structure, and the second end of the grounding wire is electrically connected to the ground. With the above configuration, when the connecting cable is retracted or extended, it can drive the base to rise or fall relative to the device to be grounded, thus avoiding the problem of operators manually pulling up the base, i.e., avoiding the problem of the operator having to exert a lot of effort when manually pulling up the pole. When the base rises relative to the device to be grounded, it can drive the position adjustment structure to move towards the device to be grounded, and then the position adjustment structure drives the clamping structure to move towards the drain line of the device to be grounded, so that the clamping structure can clamp the drain line. The position adjustment structure can move the clamping structure towards the drain line, making it easier for the clamping structure to grip the drain line. Therefore, the technical solution of this application effectively solves the problem of laborious operation when the operator pulls up the rod in related technologies. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0030] In existing technologies, many grounding wire connection points are perpendicular to the ground, requiring operators to hold the grounding wire's operating rod parallel to the grounding wire, making the operation difficult. This embodiment describes a grounding robot for 220kV substations. By researching and developing a compact and lightweight robot, this robot can replace manual labor in installing and removing grounding wires for 220kV and above substations. This significantly reduces workload, improves efficiency during grounding wire installation and removal, ensures operational safety, and changes the long-standing reliance on manual labor for grounding wire installation.

[0031] like Figure 1 and Figure 3 As shown, the grounding device in this embodiment includes: a base 10, a hoisting mechanism 20, a clamping structure 30, a position adjustment structure 40, and a grounding wire 50. The hoisting mechanism 20 is mounted on the base 10 and has a connecting cable 21. The free end of the connecting cable 21 can be connected to the device to be grounded, and the retraction and extension of the connecting cable 21 can cause the base 10 to rise and fall relative to the device to be grounded. The clamping structure 30 is movably connected to the base 10. The position adjustment structure 40 is connected between the base 10 and the clamping structure 30, and can move the clamping structure 30 in both horizontal and vertical directions, so that the clamping structure 30 can move to the position where it clamps the drain wire of the device to be grounded. The first end of the grounding wire 50 is mounted on the clamping structure 30, and the second end of the grounding wire 50 is electrically connected to the ground.

[0032] Using the technical solution of this embodiment, a hoisting mechanism 20 is provided on the base 10. The hoisting mechanism 20 has a connecting cable 21, the free end of which is connected to the device to be grounded. When the connecting cable 21 is retracted or extended, it can drive the base 10 to rise or fall relative to the device to be grounded. A clamping structure 30 is movably connected to the base 10. A position adjustment structure 40 is connected between the base 10 and the clamping structure 30. The position adjustment structure 40 can drive the clamping structure 30 to move in the horizontal and vertical directions, so that the clamping structure 30 can move to the position of clamping the lead wire of the device to be grounded. The first end of the grounding wire 50 is provided on the clamping structure 30, and the second end of the grounding wire 50 is electrically connected to the ground. With the above configuration, when the connecting cable 21 is retracted or extended, it can drive the base 10 to rise or fall relative to the device to be grounded, thus avoiding the problem of operators having to manually pull up the base 10, that is, avoiding the problem of operators having to exert a lot of effort when manually pulling up the pole. When the base 10 rises relative to the device to be grounded, it can move the position adjustment structure 40 toward the device to be grounded. The position adjustment structure 40 then moves the clamping structure 30 toward the drain line of the device to be grounded, allowing the clamping structure 30 to clamp the drain line. The position adjustment structure 40 can also move the clamping structure 30 toward the drain line, making it easier for the clamping structure 30 to clamp the drain line. Therefore, the technical solution of this embodiment effectively solves the problem of laborious operation when the operator pulls the rod in related technologies.

[0033] It should be noted that the hoisting mechanism 20 also includes a fourth driving component and a reel that drives and cooperates with the fourth driving component. The reel is mounted on the base, and the first end of the connecting cable 21 is wound around the reel, while the second end of the connecting cable 21 is a free end. The fourth driving component includes a third driving motor.

[0034] like Figure 2 and Figure 3 As shown, in this embodiment, the position adjustment structure 40 includes a first adjustment rod 41 and a second adjustment rod 42. The first adjustment rod 41 is movably connected to the base 10 along a first preset direction, and the second adjustment rod 42 is movably disposed on the first adjustment rod 41 along a second preset direction. The first adjustment rod 41 extends along the second preset direction, and the clamping structure 30 is disposed on the second adjustment rod 42. The first preset direction and the second preset direction are perpendicular to each other, with the first preset direction being horizontal and the second preset direction being vertical. The first adjustment rod 41 can move along the first preset direction, thereby driving the second adjustment rod 42 to move along the first preset direction. The second adjustment rod 42 can move along the second preset direction, thus allowing the second adjustment rod 42 to move relative to the base 10 in both the first and second preset directions. That is, the second adjustment rod 42 can drive the clamping structure 30 to move in both the first and second preset directions, making it easier for the clamping structure 30 to clamp the drain wire.

[0035] Of course, in other embodiments, the second preset direction can be a horizontal direction, and the first preset direction can be a vertical direction.

[0036] like Figure 3 and Figure 5 As shown, in this embodiment, the position adjustment structure 40 further includes a first guide rod 43, a first driving member 44, and a mounting base 45. The first guide rod 43 is disposed on the base 10 and extends along a first preset direction. The first driving member 44 and the mounting base 45 are both disposed on the first guide rod 43. The first driving member 44 drives the mounting base 45 to move along the extension direction of the first guide rod 43. The first adjustment rod 41 is disposed on the mounting base 45. The first driving member 44 can drive the mounting base 45 to move along the first preset direction on the first guide rod 43, thereby the mounting base 45 can drive the first adjustment rod 41 to move along the first preset direction.

[0037] It should be noted that the base 10 has a first receiving space and a second receiving space communicating with the outside of the base 10. The second receiving space is located below the first receiving space, and a partition with a connecting hole is provided between the second receiving space and the first receiving space. The second end of the connecting cable 21 extends out of the base 10 through a first clearance hole on the base 10. The first clearance hole communicates with the first receiving space and is located at the top of the base 10. The hoisting mechanism 20 is located in the first receiving space. The first driving member 44 is located in the second receiving space. The first guide rod 43 extends out of the base 10 through the second clearance hole on the base 10. The mounting base 45 is located on the part of the first guide rod 43 outside the base 10, and the first driving member 44 is located on the part of the first guide rod 43 inside the second receiving space. The second clearance hole communicates with the second receiving space.

[0038] From the top to the bottom of the base 10, the cross-sectional area of ​​the base 10 gradually increases. This makes the base 10 more aesthetically pleasing and compact, facilitating its miniaturization and weight reduction. The sides of the base 10 also have multiple flat surfaces, which facilitate support for the base 10 when it is close to the ground.

[0039] Specifically, the mounting base 45 includes a first mounting plate and a second mounting plate. The first mounting plate extends along the extension direction of the first guide rod 43, and the second mounting plate extends along a third preset direction, that is, the first mounting plate and the second mounting plate are arranged perpendicularly. The first adjusting rod 41 is connected to the second mounting plate.

[0040] A first mounting space is provided on the first guide rod 43. The position adjustment structure 40 also includes a slider, which is movably disposed within the first mounting space along a first preset direction. The first mounting plate is connected to the slider. A sliding protrusion is provided on the side wall of the slider, and a sliding groove is provided on the side wall of the first mounting space. The sliding protrusion and the sliding groove slide together to allow the slider to slide smoothly. The first driving component 44 includes a first driving motor and a driving screw. The first driving motor drives the driving screw to rotate, and the driving screw drives the slider to slide within the first mounting space.

[0041] The first guide rod 43 is also provided with a clearance space, and the first driving component 44 also includes a cross-slider coupling, which is connected between the output shaft of the first drive motor and the drive screw. The cross-slider coupling is located within the clearance space.

[0042] The first adjusting rod 41 has the same structure as the first guide rod 43.

[0043] The position adjustment structure 40 also includes a third connecting plate, which is movably mounted on the first adjusting rod 41 along a second preset direction, and the second adjusting rod 42 is mounted on the third connecting plate. The third connecting plate has a clearance groove, and a portion of the second adjusting rod 42 is disposed within the clearance groove.

[0044] like Figure 4 As shown, in this embodiment, the position adjustment structure 40 further includes a second driving member 46 disposed on the second adjusting rod 42. The second driving member 46 drives the clamping structure 30 to rotate around a third preset direction. The first preset direction, the second preset direction, and the third preset direction are arranged perpendicularly to each other. The second driving member 46 can drive the clamping structure 30 to rotate around the third preset direction, that is, the clamping structure 30 can move toward the drainage line, which facilitates the clamping structure 30 clamping the drainage line.

[0045] It should be noted that the second driving component 46 also includes the first driving motor.

[0046] like Figure 1 and Figure 6 As shown, in this embodiment, the clamping structure 30 includes a mounting frame 31, a first clamping part 32, a second clamping part 33, and a third driving member 34. Both the first clamping part 32 and the third driving member 34 are mounted on the mounting frame 31. The third driving member 34 drives the second clamping part 33 to move towards the top of the first clamping part 32. The mounting frame 31 supports the first clamping part 32 and the third driving member 34. The third driving member 34 drives the second clamping part 33 to move towards the top of the first clamping part 32, thereby enabling the second clamping part 33 and the first clamping part 32 to clamp the drain wire, thus achieving the connection between the clamping structure 30 and the drain wire.

[0047] The second driving member 46 also includes a rotating rod and a mounting block. The rotating rod is connected to the output shaft of the second driving member 46, and the mounting block is rotatably mounted on the second adjusting rod 42. The rotating rod is connected to the mounting block, and the mounting frame 31 is mounted on the mounting block.

[0048] like Figure 6 As shown, in this embodiment, the clamping structure 30 further includes a connecting cylinder 35 connected to the third driving member 34 and a driving rod 36 connected to the second clamping part 33. The connecting cylinder 35 and the driving rod 36 are driven together. The first end of the driving rod 36 is inserted into the connecting cylinder 35, and the cross-section of the first end of the driving rod 36 is polygonal. The second end of the driving rod 36 is connected to the second clamping part 33. The third driving member 34 can drive the connecting cylinder 35 to move, and the connecting cylinder 35 can drive the driving rod 36 to move, so that the driving rod 36 can drive the second clamping part 33 to move toward the top of the first clamping part 32. The first end of the driving rod 36 has a polygonal cross-section, which prevents relative rotation between the driving rod 36 and the connecting cylinder 35, that is, allows the driving rod 36 to effectively drive the movement of the connecting cylinder 35.

[0049] The third driving component 34 includes a second driving motor. A second mounting space is provided on the mounting frame 31, and a connecting cylinder 35 is disposed within the first mounting space. The output shaft of the second driving motor extends from the mounting frame 31 into the second mounting space and is connected to the connecting cylinder 35. Both the connecting cylinder 35 and the driving rod 36 extend along a second preset direction.

[0050] like Figure 6 As shown, in this embodiment, the first clamping part 32 includes a clamping head 321, a connecting rod 322, and a second guide rod 323 connected between the clamping head 321 and the connecting rod 322. The second clamping part 33 includes a clamping block 331 and a guide groove 332 disposed on the side of the clamping block 331. The second guide rod 323 passes through the guide groove 332 and is guided and engaged with the guide groove 332. The connecting rod 322 is inserted into the mounting frame 31 near the side of the second clamping part 33. The driving rod 36 is threadedly engaged with the connecting rod 322. The guide groove 332 can provide guidance for the movement of the second guide rod 323, so that the second guide rod 323 can move smoothly toward the clamping head 321. The cooperation between the guide groove 332 and the second guide rod 323 can also prevent relative rotation between the second guide rod 323 and the clamping block 331. The connecting rod 322 is inserted into the side of the mounting frame 31 near the first clamping part 32, so that the connecting rod 322 can be connected to the mounting frame 31, and thus the clamping block 331 will not move when it moves toward the clamping head.

[0051] It should be noted that the middle part of the clamping head 321 protrudes away from the connecting rod 322. The first end of the grounding wire is connected to the connecting rod 322. A mounting groove is provided on the side of the mounting frame 31 near the second clamping part 33, and the connecting rod 322 is inserted into the mounting groove, which extends along a first preset direction.

[0052] like Figure 6 As shown, in this embodiment, the clamping block 331 includes a first upright plate 3311, a second upright plate 3312, and a connecting plate 3313 connecting the first upright plate 3311 and the second upright plate 3312. A guide groove 332 is formed between the side of the first upright plate 3311 near the second guide rod 323 and the side of the second upright plate 3312 near the second guide rod 323. The second end of the drive rod 36 is connected to the side of the connecting plate 3313 away from the clamping head 321. The connecting plate 3313 can connect the first upright plate 3311 and the second upright plate 3312. The drive rod 36 can drive the connecting plate 3313 to move, thereby the connecting plate 3313 can drive the first upright plate 3311 and the second upright plate 3312 to move towards the clamping head 321.

[0053] It should be noted that the first upright plate 3311 has a first arc-shaped recess in its center, the second upright plate 3312 has a second arc-shaped recess in its center, and the connecting plate 3313 has a third arc-shaped recess in its center. The first, second, and third arc-shaped recesses are interconnected. The center portions of the first, second, and third arc-shaped recesses all protrude in a direction away from the clamping head 321. The drain line is clamped between the first, second, and third arc-shaped recesses and the center portion of the clamping head 321.

[0054] like Figure 7 and Figure 8 As shown, in this embodiment, the grounding device further includes a limiting structure 60 disposed on the base 10, and the middle part of the grounding wire 50 passes through the limiting structure 60. Through the above-described arrangement, the relative position between the base 10 and the grounding wire 50 can remain stable when the base 10 is raised or lowered, preventing the grounding wire 50 from swaying and affecting the raising or lowering of the base 10.

[0055] like Figure 7 and Figure 8As shown, in this embodiment, the limiting structure 60 includes a connecting seat 61, a limiting plate 62, a limiting protrusion 63, and a limiting groove 64. The limiting plate 62 is swayably disposed on the connecting seat 61. The connecting seat 61 is provided with a receiving space 611 and a notch 612 communicating with the receiving space 611. The limiting protrusion 63 is disposed on the limiting plate 62, and the limiting groove 64 is disposed on the connecting seat 61 and engages with the limiting protrusion 63 for limiting. The middle part of the grounding wire 50 enters the receiving space 611 through the notch 612, and the limiting protrusion 63 is connected within the notch 612. The notch 612 allows the grounding wire 50 to enter the receiving space 611. When the limiting plate 62 swings toward the base 10, the limiting protrusion 63 engages with the limiting groove 64 for limiting, thus limiting the grounding wire 50 within the receiving space 611.

[0056] It should be noted that the limiting plate 62 has a clearance recess on the side facing the top of the base 10, and the connecting seat 61 has a protrusion on the side away from the top of the base 10, the protrusion engaging with the clearance recess. A limiting protrusion 63 is located below the clearance recess, and the protrusion is located above the limiting groove 64. The limiting structure 60 also includes a connecting shaft, which connects the connecting seat 61 and the limiting plate 62, and the limiting plate 62 swings around the axis of the connecting shaft. The limiting groove 64 has a circular structure. The connecting seat 61 is located in one of multiple planes perpendicular to the first preset direction, and is on the same side of the base as the clamping structure 30.

[0057] The limiting structure 60 also includes a mounting rod. The first end of the mounting rod is connected to the side of the connecting seat 61 facing the base 10. An opening groove is provided in the middle of the mounting rod, extending along the direction from the connecting seat 61 to the base 10. The second end of the mounting rod is inserted into a mounting hole on the base 10. The mounting hole is located on the side of the base 10 and in a portion of the structure close to the side of the base 10. The diameter of the first end of the mounting rod is smaller than the maximum diameter of the protrusion. The second end of the mounting rod has a protrusion. From the second end of the mounting rod to the first end, the distance between the protrusion and the axis of the mounting rod gradually increases. This ensures that after the protrusion is inserted into the mounting hole, the second end of the mounting rod can be stably connected to the base 10.

[0058] The grounding device also includes a U-shaped hook and a mounting box. The mounting box is located in the middle of the bottom of the base. The U-shaped hook is installed inside the mounting box. A first clearance groove is provided on the side wall of the mounting box, and a second clearance groove is provided on the U-shaped hook. The first clearance groove and the second clearance groove are correspondingly arranged. Part of the grounding wire is inserted through the U-shaped hook. This allows the grounding wire to be fixed in the middle of the grounding device, maintaining the stability of the center of gravity of the grounding device and ensuring the stable raising and lowering of the base 10.

[0059] In use, the grounding device of this embodiment drives the base 10 to rise and fall through the winch mechanism 20, the first adjusting rod 41 drives the second adjusting rod 42 to move along the first preset direction, the second adjusting rod 42 moves along the second preset direction, and the clamping structure 30 rotates around the third preset direction, so that the clamping structure 30 can more easily clamp the drain wire.

[0060] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0061] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0062] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
