Description

Technical Field

[0001] The invention relates to the technical field of electric power engineering, and in particular to a grounding device for hanging and removing a grounding wire of an unmanned aerial vehicle used in electric power engineering. Background Art

[0002] Traditional manual electrical testing and installation and removal of grounding wires require operators to carry a transmission rope to the tower, and then use the transmission rope to transfer the tester and grounding wire to the tower, test the electricity phase by phase, and hang and remove the grounding wire. This process is time-consuming and requires a high level of physical fitness and technical proficiency from the maintenance personnel. At the same time, there are safety risks in high-altitude operations. In order to improve the stability and safety of power grid operation, reduce the workload of maintenance personnel, and ensure personal safety, drone hanging and removal of grounding wire technology came into being.

[0003] Therefore, based on the existing drone grounding device, in actual use, the grounding wire is hung on the conductor using a drone, but this method cannot guarantee that the grounding hook will not fall due to shaking, which may cause the equipment to lose grounding protection, increase the risk of equipment failure and electric shock to personnel, and thus fail to ensure the safety of the staff. In addition, during the operation of the grounding hook, the strong pulling force may cause the grounding hook to separate from the conductor, lose the grounding effect, and fail to ensure the safety of the staff.

[0004] At the same time, after the grounding hook is hung on the outside of the wire, it is easy to swing on the outside of the wire. The shaking may cause the contact point between the grounding hook and the wire to be unstable during conduction, resulting in increased contact resistance. The increase in contact resistance will cause the current to generate additional heat when flowing through this point, affecting the grounding effect. Moreover, unstable contact may also cause intermittent grounding faults. In some cases, the grounding hook may briefly lose good contact with the wire, causing the grounding line to be disconnected instantly. For this reason, we propose a grounding device for hanging and removing grounding wires by drones for power engineering. Summary of the invention

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] As introduced in the background technology, in order to solve the deficiencies existing in the prior art and the above technical problems, the present application proposes a grounding device for hanging and removing ground wires by drones for power engineering.

[0042] Embodiment 1, as Figure 1-Figure 4 As shown, a grounding device for hanging and removing grounding wires by drones for power engineering comprises an iron tower 1, a conductor 2 and an inspection drone 8, a hanger 9 is suspended at the bottom of the inspection drone 8, two hanging wires 10 are fixedly connected to the bottom of the hanger 9, a triangular hook 11 is fixedly connected to the bottom of the hanging wire 10, a grounding clamp 3 is hung on the triangular hook 11, the two hanging wires 10 are one long and one short, the grounding clamp 3 at the bottom of the long hanging wire 10 is used to hang on the grounding end of the iron tower 1, and the grounding clamp 3 at the bottom of the short hanging wire 10 is used to hang on the outside of the conductor 2, a conductive block 14 is fixedly connected to the inside of the grounding shell 12, and a conductive sheet 15 is fixedly connected to one side of the conductive block 14;

[0043] A grounding clamp 3, which is used for grounding the conductor 2. Two grounding clamps 3 are provided, which are hung on the grounding end of the iron tower 1 and the outside of the conductor 2 respectively. The grounding clamp 3 includes a grounding shell 12. A conductor mounting plate 13 is fixedly connected to the inside of the grounding shell 12. A hook ring 18 is provided on the top of the conductor mounting plate 13. The hook ring 18 is adapted to the triangular hook 11. One side of the two conductor mounting plates 13 is fixedly connected to the same grounding conductor 7.

[0044] By means of the above-mentioned structure, the two grounding clamps 3 can be hung on the grounding end of the iron tower 1 and the outside of the conductor 2, respectively. Specifically, after the conductor 2 is tested for electricity, the two grounding clamps 3 are respectively hooked on the corresponding triangular hooks 11 through the hook rings 18. At this time, the inspection drone 8 is started, and the inspection drone 8 rises to drive the hanger 9 to rise, and the hanger 9 rises to drive the two hook rings 18 to rise, and the two hook rings 18 rise to respectively drive the grounding clamps 3 thereon to rise. When the hanging position is reached, the grounding clamp 3 at the bottom of the long hanging wire 10 is first hung on the iron tower 1. The grounding end of the tower 1 is disconnected from the hook ring 18 of the grounding clamp 3 hung on the grounding end of the iron tower 1 and the triangular hook 11 thereon. At this time, the grounding clamp 3 at the bottom of the short hanging wire 10 is hung on the outside of the wire 2 that has been powered off. In this process, the conductive sheet 15 inside the grounding clamp 3 will abut against the outside of the iron tower 1 or the wire 2 to complete the grounding. At this time, both triangular hooks 11 are disconnected from the corresponding hook rings 18, and the inspection drone 8 can be started to return. Then the staff can climb the iron tower 1 to inspect or repair the wire 2 to improve the stability of the conduction;

[0045] When there is current in the conductor 2, the current will flow through the grounding clamp 3 outside the conductor 2 to the inside of the grounding conductor 7, then flow from the grounding conductor 7 to the inside of the grounding clamp 3 outside the iron tower 1, and then flow to the grounding end of the iron tower 1 through the grounding clamp 3 outside the iron tower 1, thereby preventing workers from being injured when inspecting or repairing the conductor 2.

[0046] like Figure 7-10 As shown, the hook mechanism 5 is used for hooking the grounding clamp 3, and the hook mechanism 5 includes a hook 34 rotatably connected to the inside of the grounding shell 12, a driven plate 39 is rotatably connected to the inside of the grounding shell 12, and a driven hook 40 is fixedly connected to one end of the driven plate 39, a release plate 41 is fixedly connected to the top of the hook 34, and a release rod 42 is fixedly connected to the inside of the release plate 41, and driving torsion springs 37 are arranged on both sides of the hook 34, and the two driving torsion springs 37 are close to each other at one end and abut against the two sides of the hook 34, and the inside of the grounding shell 12 is dampingly rotatably connected to a damping frame 36, and the two driving torsion springs 37 are separated at one end and abut against the inside of the damping frame 36;

[0047] The hook mechanism 5 also includes a mounting shaft 35 fixedly connected to the inside of the grounding shell 12, a hook 34 rotatably connected to the outside of the mounting shaft 35, two driving torsion springs 37 are movably sleeved on the outside of the mounting shaft 35, a damping frame 36 is rotatably connected to the outside of the mounting shaft 35, a support plate 38 is fixedly connected to the inside of the grounding shell 12, a driven plate 39 is rotatably connected to the inside of the support plate 38, a return torsion spring is fixedly connected to one side of the driven plate 39, and the other end of the return torsion spring is fixedly connected to the inside of the support plate 38.

[0048] By setting the above structure, the grounding clamp 3 can be hooked on the outside of the iron tower 1 or the conductor 2 to prevent the grounding clamp 3 from falling and causing grounding failure. Specifically, before using the hooking mechanism 5, the hook 34 is first opened and the release rod 42 is hooked on the inside of the driven hook 40. At this time, the two driving torsion springs 37 are in a power storage state, and the preparation work is completed. Subsequently, in the process of placing the grounding clamp 3 on the outside of the iron tower 1 or the conductor 2, the conductive sheet 15 and the driven plate 39 gradually approach and abut against the conductor 2 or the iron tower 1. Since the conductive sheet 15 is arranged on the outside of the iron tower 1 or the conductor 2, the conductive sheet 15 and the driven plate 39 gradually approach and abut against the conductor 2 or the iron tower 1. The two sides of the bottom of the moving plate 39 make the conductive sheet 15 first contact with the outside of the wire 2 or the iron tower 1 and bend, and then abut against the driven plate 39. Due to the gravity of the grounding clamp 3 itself, when the driven plate 39 abuts against the outside of the iron tower 1 or the wire 2, it will drive the driven plate 39 to rotate, and the rotation of the driven plate 39 drives the driven hook 40 to rotate. The driven hook 40 rotates and disengages from the release rod 42. The two driving torsion springs 37 release the pressure and drive the hook 34 to rotate. The top of the hook 34 abuts against the outside of the iron tower 1 or the wire 2, so that the grounding clamp 3 is hooked.

[0049] It is worth mentioning that since the damping frame 36 is connected to the inside of the grounding shell 12 for damping rotation, and the two ends of the driving torsion spring 37 are respectively on one side of the hook 34 and inside the damping frame 36, the rotating damping frame 36 can indirectly control the force storage strength of the two driving torsion springs 37, and can accurately adjust and control the force of clamping the wire 2. More specifically, the force storage strength of the driving torsion spring 37 is smaller than the damping rotation strength of the damping frame 36 inside the grounding shell 12, thereby avoiding the rotation of the damping frame 36 during the driving torsion spring 37.

[0050] Embodiment 2, as Figure 9-13As shown, a grounding device for hanging and removing grounding wires of unmanned aerial vehicles for power engineering, combined with the basis of embodiment 1, a self-locking mechanism 6, the self-locking mechanism 6 is used for self-locking after the grounding clamp 3 is hooked, the self-locking mechanism 6 includes a self-locking frame 49 rotatably connected to the inside of the grounding shell 12, both sides of the damping frame 36 are provided with self-locking grooves 44, both sides of the hook 34 are fixedly connected with self-locking rods 43, the self-locking rods 43 are slidably connected to the inside of the self-locking grooves 44, the bottom of the self-locking frame 49 abuts against the outside of the self-locking rod 43, the inside of the wire mounting plate 13 is slidably connected with a sliding rod 17, the hook ring 18 is inserted at the top of the sliding rod 17, and the bottom of the sliding rod 17 is slidably connected to the inside of the self-locking frame 49;

[0051] The self-locking mechanism 6 also includes a sliding sleeve 16 fixedly connected to the inside of the wire mounting plate 13, a sliding rod 17 slidably connected to the inside of the sliding sleeve 16, a sliding block 46 is fixedly connected to the bottom of the sliding rod 17, a compression spring 47 is movably sleeved on the outside of the sliding rod 17, the top of the sliding block 46 abuts against the bottom of the compression spring 47, the top of the compression spring 47 abuts against the bottom of the wire mounting plate 13, a sliding hole 51 is opened on one side of the sliding block 46, a sliding rod 48 is inserted into the inside of the self-locking frame 49, and the sliding rod 48 is slidably connected to the inside of the sliding hole 51.

[0052] The above-mentioned structure can prevent the grounding clamp 3 from being separated from the iron tower 1 or the wire 2 under the action of external force, causing grounding failure. Specifically, when the inspection drone 8 drives the grounding clamp 3 to hook on the outside of the iron tower 1 or the wire 2, the inspection drone 8 pulls the hook ring 18 through the triangular hook 11. Due to the gravity of the grounding clamp 3 itself, when the grounding clamp 3 is not placed outside the iron tower 1 or the wire 2, the compression spring 47 is in a compressed state, and the bottom of the self-locking frame 49 is separated from the outside of the self-locking rod 43.

[0053] The self-locking rod 43 is enabled to slide inside the self-locking groove 44. When the grounding clamp 3 is placed outside the iron tower 1 or the conductor 2 by the inspection drone 8, the hook 34 rotates to hook the grounding clamp 3 on the outside of the iron tower 1 or the conductor 2. After the hooking is completed, the inspection drone 8 is separated from the hook ring 18, and the compression spring 47 extends to drive the slide rod 17 to slide downward inside the sliding sleeve 16. The downward sliding of the slide rod 17 drives the sliding block 46 to move downward. The downward movement of the sliding block 46 drives the self-locking frame 49 to rotate. While the self-locking frame 49 rotates, the sliding rod 48 slides inside the sliding block 46, so that the self-locking frame 49 can rotate. The self-locking frame 49 rotates to seal the self-locking groove 44, so that the self-locking rod 43 cannot slide into the self-locking groove 44, thereby effectively preventing the grounding clamp 3 from being subjected to external force, causing the hook 34 to open and causing the grounding clamp 3 to fall off;

[0054] It is worth mentioning that if the abutment between the self-locking frame 49 and the self-locking rod 43 is not released, when the driven hook 40 is separated from the release rod 42, the extension force of the driving torsion spring 37 will act on the self-locking rod 43, but since the self-locking frame 49 abuts against the self-locking rod 43, the hook 34 cannot rotate;

[0055] When the grounding clamp 3 needs to be removed, the two grounding clamps 3 are hooked up in turn by the inspection drone 8. During the hooking process, the inspection drone 8 rises and drives the triangular hook 11 to rise. The rising of the triangular hook 11 drives the hook ring 18 to rise. The rising of the hook ring 18 drives the slide bar 17 to slide upward inside the slide sleeve 16 to compress the compression spring 47. The slide bar 17 slides upward and drives the self-locking frame 49 to rotate. The self-locking frame 49 rotates away from the self-locking groove 44, so that the self-locking rod 43 can slide into the self-locking groove 44. At this time, the grounding clamp 3 can be pulled down directly from the outside of the tower 1 or the conductor 2.

[0056] Return grooves 45 are formed on both sides of the damping frame 36 , and return rods 50 are fixedly connected to both sides of the inner wall of the self-locking frame 49 . The return rods 50 are slidably connected to the inside of the return grooves 45 .

[0057] In combination with the above scheme, when the grounding clamp 3 needs to be removed, the worker can also slide the grounding clamp 3 on the outside of the conductor 2 to one end of the conductor 2 and stand on the iron tower 1. At this time, the damping frame 36 is rotated, and the rotation of the damping frame 36 drives the return groove 45 to move. The movement of the return groove 45 drives the self-locking frame 49 to rotate. At this time, the self-locking frame 49 rotates away from the self-locking groove 44, and the grounding clamp 3 on the outside of the conductor 2 can be removed. Then, the grounding clamp 3 on the outside of the iron tower 1 can be removed in this way;

[0058] It is worth mentioning that in the process of removing the grounding clamp 3 by rotating the damping frame 36, since the two ends of the driving torsion spring 37 are respectively against one side of the hook 34 and the inside of the damping frame 36, the rotating damping frame 36 can reduce the clamping force between the grounding clamp 3 and the tower 1 or the conductor 2, making it easier to remove the grounding clamp 3.

Based on the first and second embodiments, a positioning mechanism 4 is provided at the bottom of the grounding shell 12. The positioning mechanism 4 facilitates hanging the grounding clamp 3 on the grounding end of the iron tower 1 or the outside of the wire 2.

A second through slot 22 is provided at the bottom of the plug block 19. Two sliding blocks 23 are slidably connected inside the second through slot 22.

The interiors of the four third through slots 27 are all threadedly connected with sliding bolts 28, and every two sliding bolts 28 form a group. Each group of sliding bolts 28 is slidably connected to the interiors of adjacent sliding blocks 23.

[0062] By setting the above structure, the difficulty of placing the grounding clamp 3 outside the iron tower 1 or the conductor 2 can be reduced. Specifically, when the iron tower 1 is needed, the plugs 30 at one end of the two plug racks 29 are respectively inserted into the corresponding plug holes 31 and the inside of the second through slot 22. When the plug 30 is inserted into the second through slot 22, it will first abut against one side of the sliding block 23. Since one side of the sliding block 23 and the top of the plug 30 are arranged inclined, the two sliding blocks 23 approach each other during the insertion of the plug 30 into the second through slot 22, and finally the second slot 33 cooperates with the first slot 32. At this time, the button spring 24 stretches, and the button spring 24 stretches to drive the spring button 21 to move. The movement of the spring button 21 drives the limiting rod 25 to slide inside the limiting slot 26, thereby causing the two sliding blocks 23 to gradually move away, so that the second slot 33 abuts against the first slot 32, and the plug rack 29 is clamped on the outside of the plug block 19. At this time, the opening at the bottom of the grounding clamp 3 is more convenient for hanging through the guidance of the positioning mechanism 4;

[0063] When the two racks 29 need to be removed, the spring button 21 is pressed, the button spring 24 is compressed, and at the same time the spring button 21 moves to drive the limit rod 25 to slide inside the limit groove 26, thereby causing the two sliding blocks 23 to gradually approach each other, so that the second slot 33 is separated from the first slot 32. At this time, the rack 29 can be pulled out to pull the plug 30 out of the inside of the socket 31.

[0064] Embodiment 4, as Figure 14-16 As shown, a grounding device for hanging and removing grounding wires for unmanned aerial vehicles for power engineering is provided. Based on the first, second and third embodiments, both sides of the hook 34 are provided with abutment grooves 52, one end of each of the two driving torsion springs 37 abuts against one side of the abutment grooves 52, one side of each of the two abutment grooves 52 is fixedly connected with a hydraulic cylinder 53, the interior of the hydraulic cylinder 53 is slidably connected with a hydraulic block 54, the interior of the hydraulic cylinder 53 is filled with hydraulic oil, one side of the hydraulic cylinder 53 is connected with a hydraulic pipe 55, the interior of the hook 34 is fixedly connected with a hydraulic box 56, and the two hydraulic pipes 55 are connected with the top of the hydraulic box 56;

[0065] An extension spring 57 is fixedly connected to the bottom of the inner wall of the hydraulic box 56, and a sliding plate 58 is fixedly connected to the top of the extension spring 57. The sliding plate 58 is airtightly slidably connected inside the hydraulic box 56. A driving block 60 is slidably connected to one side of the hook 34, and a memory metal sheet 61 is fixedly connected to the top of the driving block 60. A telescopic rod 59 is fixedly connected to the bottom of the driving block 60. The telescopic rod 59 extends to the bottom of the hydraulic box 56 and is fixedly connected to the top of the sliding plate 58.

[0066] By setting the above structure, the grounding effect can be improved. Specifically, when the hook mechanism 5 is working, the contact force of the driving torsion spring 37 on the hook 34 is reduced, resulting in a decrease in the hydraulic oil pressure on the left side of the hydraulic box 56, and the extension spring 57 is extended. The extension spring 57 drives the sliding plate 58 to move, and the sliding plate 58 moves to drive the telescopic rod 59 to move. The telescopic rod 59 moves to drive the driving block 60 to slide on the top of the hook 34. The driving block 60 moves to drive the memory metal sheet 61 to move and fit with the outside of the iron tower 1 or the conductor 2. When there is current, the memory metal sheet 61 is heated and the memory metal sheet 61 is bent, which expands the fitting surface of the memory metal sheet 61 and the iron tower 1 or the conductor 2, thereby improving the grounding effect.

[0067] When the grounding clamp 3 needs to be removed, the hook 34 is rotated under force, increasing the pressing force of the driving torsion spring 37 on the hook 34, so that the hydraulic oil pressure inside the hydraulic box 56 is increased, the extension spring 57 is compressed, and the memory metal sheet 61 returns to its original position, which facilitates the removal of the grounding clamp 3.

[0068] The working principle of the present invention is as follows: after the wire 2 is tested for electricity, the plugs 30 at one end of the two plug racks 29 are respectively inserted into the corresponding jacks 31 and the inside of the second through slots 22. In the process of inserting the plug 30 into the second through slots 22, it will first abut against one side of the sliding block 23. Since one side of the sliding block 23 and the top of the plug 30 are arranged at an angle, the two sliding blocks 23 approach each other in the process of inserting the plug 30 into the second through slots 22, and finally the second slot 33 cooperates with the first slot 32. At this time, the button spring 24 stretches, and the button spring 24 stretches to drive the spring button 21 to move. The movement of the spring button 21 drives the limiting rod 25 to slide inside the limiting slot 26, thereby causing the two sliding blocks 23 to gradually move away from each other, so that the second slot 33 abuts against the first slot 32, and the plug rack 29 is clamped to the outside of the plug block 19. At this time, the opening at the bottom of the grounding clamp 3 is more convenient for hanging through the guidance of the positioning mechanism 4;

[0069] At this time, the hook 34 is opened and the release rod 42 is hooked inside the driven hook 40. At this time, the two driving torsion springs 37 are in a state of storing force, and the preparation work is completed. At this time, the two grounding clamps 3 are respectively hooked on the corresponding triangular hooks 11 through the hook rings 18, and the inspection drone 8 is started. The inspection drone 8 rises and drives the hanger 9 to rise. The rise of the hanger 9 drives the two hook rings 18 to rise. The rise of the two hook rings 18 drives the grounding clamps 3 thereon to rise. Due to the gravity of the grounding clamp 3 itself, when the grounding clamp 3 is not placed outside the iron tower 1 or the conductor 2, the compression spring 47 is in a compressed state, and at the same time, the bottom of the self-locking frame 49 is separated from the outside of the self-locking rod 43. At this time, the self-locking frame 49 releases the movement restriction of the self-locking rod 43, so that the self-locking rod 43 can slide inside the self-locking groove 44;

[0070] When the hanging position is reached, the grounding clamp 3 at the bottom of the long hanging wire 10 is first hung on the grounding end of the iron tower 1, and the hook ring 18 of the grounding clamp 3 hung on the grounding end of the iron tower 1 is separated from the triangular hook 11 thereon. At this time, the grounding clamp 3 at the bottom of the short hanging wire 10 is hung on the outside of the wire 2 that has been powered off. In this process, the conductive sheet 15 and the driven plate 39 gradually approach and abut against the wire 2 or the iron tower 1. Since the conductive sheet 15 is arranged on both sides of the bottom of the driven plate 39, the conductive sheet 1 5 first contacts with the outside of the conductor 2 or the iron tower 1 and bends, and then contacts with the driven plate 39. Due to the gravity of the grounding clamp 3 itself, when the driven plate 39 contacts with the outside of the iron tower 1 or the conductor 2, the driven plate 39 is driven to rotate, and the rotation of the driven plate 39 drives the driven hook 40 to rotate. The driven hook 40 rotates and disengages from the release rod 42. The two driving torsion springs 37 release the pressure and drive the hook 34 to rotate. The top of the hook 34 contacts with the outside of the iron tower 1 or the conductor 2, and the grounding clamp 3 is hooked.

[0071] After the hooking is completed, the two triangular hooks 11 are separated from the corresponding hook rings 18, and the compression spring 47 stretches to drive the slide rod 17 to slide downward inside the slide sleeve 16, and the slide rod 17 slides downward to drive the slide block 46 to move downward, and the slide block 46 moves downward to drive the self-locking frame 49 to rotate. While the self-locking frame 49 rotates, the slide rod 48 slides inside the slide block 46, so that the self-locking frame 49 can rotate, and the self-locking frame 49 rotates to seal the self-locking groove 44, so that the self-locking rod 43 cannot slide into the self-locking groove 44, and the self-locking is completed;

[0072] At this time, the inspection drone 8 can be started to return, and then the staff can climb the tower 1 to inspect or repair the wire 2 to improve the stability of the conduction;

[0073] When the conductor 2 has current, the current will flow through the grounding clamp 3 outside the conductor 2 to the inside of the grounding conductor 7, then flow from the grounding conductor 7 to the inside of the grounding clamp 3 outside the iron tower 1, and then flow through the grounding clamp 3 outside the iron tower 1 to the grounding end of the iron tower 1, thereby preventing workers from being injured when inspecting or repairing the conductor 2;

[0074] When the grounding clamp 3 needs to be removed, the two grounding clamps 3 are hooked up in sequence by the inspection drone 8. During the hooking process, the inspection drone 8 rises and drives the triangular hook 11 to rise, and the triangular hook 11 rises and drives the hook ring 18 to rise, and the hook ring 18 rises and drives the slide bar 17 to slide upward inside the sliding sleeve 16, compressing the compression spring 47, and the slide bar 17 slides upward to drive the self-locking frame 49 to rotate, and the self-locking frame 49 rotates away from the self-locking groove 44, so that the self-locking rod 43 can slide into the self-locking groove 44. At this time, the grounding clamp 3 can be directly pulled down from the outside of the iron tower 1 or the conductor 2;

[0075] At the same time, when it is necessary to remove the grounding clamp 3, a worker can slide the grounding clamp 3 on the outside of the conductor 2 to one end of the conductor 2 and stand on the iron tower 1. At this time, the damping frame 36 is rotated, and the damping frame 36 rotates to drive the return groove 45 to move. The return groove 45 moves to drive the self-locking frame 49 to rotate. At this time, the self-locking frame 49 rotates away from the self-locking groove 44, and the grounding clamp 3 on the outside of the conductor 2 can be removed. Then, the grounding clamp 3 on the outside of the iron tower 1 can be removed in this way.

[0076] After the grounding clip 3 is removed and taken down, the spring button 21 is pressed again, the button spring 24 is compressed, and at the same time the spring button 21 moves to drive the limiting rod 25 to slide inside the limiting groove 26, thereby causing the two sliding blocks 23 to gradually approach each other, so that the second slot 33 is separated from the first slot 32. At this time, the plug 30 can be pulled out of the socket 31 by pulling out the bracket 29 to be retracted.

[0077] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
