Technical Field
[0001] This invention relates to the field of fire-fighting robot technology, specifically a track-mounted fire-fighting robot for rooftop photovoltaic inspection. Background Technology
[0002] Distributed photovoltaic systems are typically installed on the rooftops of industrial plants. If a fire breaks out due to abnormal weather, equipment short circuits, or roof overheating, firefighters may be unable to reach the scene immediately, leading to the fire spreading and causing significant property damage and casualties. Traditional manual inspections are inefficient and pose safety hazards; therefore, automated inspection and firefighting equipment is urgently needed.
[0003] Existing rooftop photovoltaic fire protection equipment has the following technical defects:
[0004] The method of fixing the track is cumbersome: Traditional tracks are mostly fixed to the roof one by one with bolts. During installation, it is necessary to tighten them one by one at high altitude, which is time-consuming and labor-intensive. In addition, they are prone to loosening under wind vibration or equipment movement impact, which affects the stability of robot operation.
[0005] Fire extinguishers are inconvenient to disassemble and assemble: fire extinguishing devices and mobile carriers are mostly rigidly connected by bolts. When changing the extinguishing agent or performing maintenance, tools must be carried to disassemble them one by one, which is complicated (it takes 2-3 minutes for a single person to replace them), making it difficult to meet the rapid response requirements of rooftop photovoltaic scenarios.
[0006] Poor compatibility: The track fixing structure and fire extinguishing component mounting base are mostly customized designs, which cannot be adapted to different specifications of tracks or fire extinguisher cylinders, resulting in insufficient versatility and increased equipment procurement and maintenance costs. To address this, we have launched a track-mounted fire-fighting robot for rooftop photovoltaic inspections. Summary of the Invention
[0007] The purpose of this invention is to provide a track-mounted fire-fighting robot for rooftop photovoltaic inspection, in order to solve the problems mentioned in the background art.
[0008] To achieve the above objectives, the present invention provides the following technical solution:
[0009] A track-mounted firefighting robot for rooftop photovoltaic inspection includes a track fixed to the roof and a firefighting robot component sliding on the track. A quick-clamping component is installed on the roof. When the bottom of the track is pressed into the quick-clamping component, the quick-clamping component clamps and fixes the track.
[0010] The fire-fighting robot assembly includes a movable seat that slides horizontally on a track and a rotatable camera assembly located at the front of the upper end of the movable seat. The rotatable camera assembly is used to provide fire early warning for the photovoltaic panels on the roof.
[0011] The fire extinguishing component is installed on the upper rear part of the movable base using a quick-release fixing component. The quick-release fixing component fixes the fire extinguishing component by pressing down and tightening the limit.
[0012] Preferably, the track is positioned between adjacent photovoltaic panels.
[0013] Preferably, the quick-clamping assembly includes a U-shaped limiting seat assembly fixed on the roof, a U-shaped pressing component disposed on the U-shaped limiting seat assembly, and a horizontal clamping block;
[0014] The bottom of the track is locked inside the U-shaped limiting seat assembly, and the bottom of the track presses on the U-shaped pressing assembly, causing the U-shaped pressing assembly to move downward and drive the two sets of horizontal locking blocks on the left and right to move closer to each other until the horizontal locking blocks are locked in the slots on the bottom side of the track.
[0015] Preferably, the U-shaped limiting seat assembly includes a base fixed to the roof with screws and a U-shaped limiting seat body integrally formed in the middle of the upper end of the base;
[0016] The outer side of the U-shaped limiting seat is provided with vertical grooves that are interconnected at the bottom, and the inner side of the upper part of the U-shaped limiting seat is provided with a slot for inserting a horizontal clamping block.
[0017] The U-shaped pressing assembly includes a pressure plate set at the bottom of the vertical groove and lifting seats integrally set on both sides of the upper end of the pressure plate. The bottom of the pressure plate sits on the upper end of the first spring at the bottom of the vertical groove, and the lifting seats slide in the corresponding vertical groove.
[0018] The outer end of the horizontal clamping block extends into the receiving groove inside the lifting seat, and the pin fixed to the outer end of the horizontal clamping block slides in the inclined groove on the side wall of the receiving groove.
[0019] Preferably, the movable seat has drive wheels fixed on both sides and supported on the roof, and a roller is movably provided at the lower center of the movable seat, with the roller supported on the top of the track.
[0020] Preferably, a servo motor is provided in the front inner cavity of the movable seat, and the rotatable camera assembly includes a rotating shaft connected to the upper front end of the movable seat by a bearing seat and a camera movably connected to the top of the rotating shaft. The bottom of the rotating shaft is connected to the top output end of the servo motor.
[0021] The camera has a connecting seat at the bottom, which is movably connected to the U-shaped groove at the top of the rotating shaft by a pin, and the two ends of the pin extend out of the U-shaped groove and are screwed with locking nuts.
[0022] Preferably, the fire extinguishing assembly includes a fire extinguisher bottle, and the upper rear part of the movable base is provided with a placement groove for placing the fire extinguisher bottle;
[0023] The quick-release and fixing assembly includes vertical rods set on the top of both sides of the placement slot, a top plate connected to the top of the two sets of vertical rods, a sleeve seat sleeved on the vertical rod, an arc-shaped limiting seat fixed to the inner end of the sleeve seat by a connecting arm, and an arc-shaped clamp plate slidably connected to the lower inner side of the arc-shaped limiting seat.
[0024] A second spring is also sleeved on the vertical rod, located between the top plate and the sleeve seat. An adjusting internal threaded cylinder is screwed onto the vertical rod, and the sleeve seat is supported on the top of the adjusting internal threaded cylinder.
[0025] Preferably, the lower inner side of the arc-shaped limiting seat is provided with an arc-shaped groove for sliding the arc-shaped clamp plate, and the upper end of the arc-shaped clamp plate is provided with a stud. The top of the stud extends through the arc-shaped through groove at the top of the arc-shaped groove and is screwed with a fixing nut.
[0026] Preferably, the inner diameters of the arc-shaped clamp plate and the arc-shaped limiting seat are the same.
[0027] Preferably, the top of the fire extinguisher bottle is connected to a nozzle via a solenoid valve, the end of the nozzle is screwed to a connecting sleeve, and nozzles are connected to both sides of the connecting sleeve via connecting pipes.
[0028] Compared with the prior art, the present invention has the following beneficial effects:
[0029] This invention significantly improves track installation efficiency:
[0030] The "press-linkage clamping" mechanism is adopted: after the U-shaped limit seat is pressed into the bottom of the track, the lifting seat is driven by the downward movement of the pressure plate. The horizontal clamping block is automatically embedded into the slot by the cooperation of the inclined groove and the pin. There is no need to fix each bolt individually, which shortens the installation time and reduces the intensity of high-altitude work.
[0031] Adaptive locking and anti-loosening: The rebound force of the first spring continuously acts on the pressure plate, making the horizontal locking block and the slot tightly engaged. It can resist wind vibration or robot movement impact, solve the problem of easy loosening of traditional bolt connection, and improve the stability of track fixation.
[0032] The efficiency of replacing fire extinguishing components has been significantly improved:
[0033] "Elastic pressure + arc-shaped clamp" double fixation: The arc-shaped limit seat is driven by the second spring to press down on the upper part of the fire extinguisher bottle, and locked in conjunction with the arc-shaped clamp plate. Fixing can be completed without tools, and a single person can replace the fire extinguisher bottle in seconds, which solves the tedious problem of traditional bolt connection that requires disassembly one by one.
[0034] Quick disassembly mechanism: Push the sleeve seat in the reverse direction to move the arc-shaped limit seat and arc-shaped clamp plate to the narrow part of the neck of the fire extinguisher bottle, and the fire extinguisher bottle can be removed, which can meet the emergency maintenance needs in rooftop scenarios.
[0035] Balancing compatibility and stability:
[0036] Compatible with multiple fire extinguishing equipment: By adjusting the height of the internal threaded cylinder (accommodating fire extinguisher bottle height differences of ±50mm), it is compatible with different models of 5-10L fire extinguishers, making it highly versatile.
[0037] In summary, this invention, through its innovative quick-clamping and quick-disassembly structure, solves the problems of cumbersome installation, inconvenient maintenance, and poor versatility of existing equipment, providing an efficient and reliable solution for the safe operation and maintenance of rooftop photovoltaic power stations.

[0064] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.
[0065] Example:
[0066] Please see Figure 1-18 , the present invention provides a technical solution:
[0067] A track-mounted fire-fighting robot for inspecting rooftop photovoltaic panels includes a track 2 fixed to the roof 1 and a fire-fighting robot assembly 5 sliding on the track 2, with the track 2 positioned between adjacent photovoltaic panels 4.
[0068] A quick-clamping assembly 3 is installed on the roof 1. After pressing the bottom of the track 2 into the quick-clamping assembly 3, the quick-clamping assembly 3 will clamp and fix the track 2.
[0069] The quick-clamping assembly 3 includes a U-shaped limiting seat assembly fixed on the roof 1, a U-shaped pressing assembly provided on the U-shaped limiting seat assembly, and a horizontal clamping block 35;
[0070] The bottom of the track 2 is locked inside the U-shaped limiting seat assembly. The bottom of the track 2 presses against the U-shaped pressing assembly, causing the U-shaped pressing assembly to move downward and drive the two sets of horizontal locking blocks 35 on the left and right to move closer to each other until the horizontal locking blocks 35 are locked in the slot 201 on the bottom side of the track 2.
[0071] The U-shaped limiting seat assembly includes a base 31 fixed to the roof 1 by screws 32 and a U-shaped limiting seat body 36 integrally formed in the middle of the upper end of the base 31.
[0072] The outer side of the U-shaped limiting seat 36 is provided with vertical grooves 361 that are interconnected at the bottom, and the inner side of the upper part of the U-shaped limiting seat 36 is provided with a slot 362 for inserting the horizontal clamping block 35.
[0073] The U-shaped pressing assembly includes a pressure plate 37 at the bottom of the vertical groove 361 and lifting seats 34 integrally provided on both sides of the upper end of the pressure plate 37. The bottom of the pressure plate 37 is located on the upper end of the first spring 33 at the bottom of the vertical groove 361, and the lifting seats 34 are slidably connected in the corresponding vertical groove 361.
[0074] The outer end of the horizontal clamping block 35 extends into the receiving groove 38 inside the lifting seat 34, and the pin 40 fixed to the outer end of the horizontal clamping block 35 slides in the inclined groove 39 on the side wall of the receiving groove 38.
[0075] After the bottom of the track 2 is inserted into the U-shaped limiting seat 36, the track is quickly clamped through the linkage structure of "the pressure plate 37 moves down → the lifting seat 34 drives the horizontal clamping block 35 to retract inward", which improves the installation efficiency.
[0076] After the horizontal locking block 35 is inserted into the slot 201, it forms a two-way locking with the rebound force of the first spring 33 to prevent the track 2 from loosening due to wind or robot movement vibration.
[0077] The fire-fighting robot component 5 includes a movable seat 51 that slides horizontally on the track 2 and a rotatable camera component installed at the front of the upper end of the movable seat 51. The rotatable camera component is used to provide fire warning for the photovoltaic panels 4 on the roof 1.
[0078] The movable seat 51 has drive wheels 53 fixed on both sides and supported on the roof 1, and a roller 52 is movably provided at the lower center of the movable seat 51, with the roller 52 supported on the top of the track 2.
[0079] The roller 52 slides with the track 2 to reduce horizontal movement resistance; the drive wheel 53 contacts the roof 1 to increase friction and prevent slippage, which is especially suitable for scenarios with a roof slope of ≤15°.
[0080] The dual-support structure (track 2 + roof 1) reduces the load-bearing pressure on a single track 2 and extends the service life of track 2.
[0081] The drive wheel 53 is an electrically driven wheel, which is electrically connected to the conductive plate on the side of the track 2, and under the control of the PLC controller, the drive wheel 53 rolls.
[0082] The front inner cavity of the movable base 51 is equipped with a servo motor. The rotatable camera assembly includes a rotating shaft 55 connected to the upper front end of the movable base 51 by a bearing seat 54 and a camera 58 movably connected to the top of the rotating shaft 55. The bottom of the rotating shaft 55 is connected to the top output end of the servo motor.
[0083] The servo motor is electrically connected to the PLC controller. The PLC controller can control the rotation of the camera 58 through the servo motor, thereby increasing the monitoring range of the camera 58 on the photovoltaic panel 4.
[0084] The bottom of the camera 58 is provided with a connecting seat 57, which is movably connected to the U-shaped groove at the top of the rotating shaft 55 by a pin, and the two ends of the pin extend out of the U-shaped groove and are screwed with locking nuts 56.
[0085] The camera 58 is connected to the pivot 55 via a connecting seat 57 to achieve pitch angle adjustment, and the locking nut 56 can fix the adjusted angle.
[0086] The 360° rotation of the pivot 55, combined with the pitch adjustment of the camera 58, enables a single camera to monitor both sides of the photovoltaic panel 4 and the surrounding area without blind spots, reducing the number of devices required.
[0087] The pin connection and locking nut 56 fixing method allows for flexible adjustment of the shooting angle (adjustment range 0-90°) according to the height of the photovoltaic panel 4, adapting to photovoltaic arrays of different specifications.
[0088] The top of the fire extinguisher bottle 7 is connected to a nozzle 701 via a solenoid valve 705. A connecting tube 704 is screwed to the end of the nozzle 701. The nozzles 703 are connected to both sides of the connecting tube 704 via connecting tubes 702.
[0089] The nozzle 701 is screwed to the connecting tube 704, and the connecting tubes 702 are symmetrically distributed on both sides of the connecting tube 704 to ensure that the extinguishing agent is evenly sprayed through the two nozzles 703, and the coverage area is expanded to 1.5 times the width of the photovoltaic panel.
[0090] The 705 solenoid valve features an electrically controlled switch design that enables millisecond-level response, preventing the waste of extinguishing agent.
[0091] Camera 58 captures the surface temperature and abnormal light spots of photovoltaic panel 4. When a fire hazard is detected by image recognition technology, the PLC controller controls the drive wheel 53 to roll, so that the fire robot component 5 moves to the corresponding fire location. Then, the PLC controller controls the solenoid valve 705 to open, so that the extinguishing agent in the fire extinguisher bottle 7 is diverted to the two connecting pipes 702 through the nozzle 701 and connecting tube 704, and finally sprayed towards the fire point through the nozzle 703.
[0092] The two sides of the connecting tube 704 can also be directly connected to the rubber hose nozzle. The rubber hose nozzle is fixed on both sides of the camera 58. By combining the rubber hose nozzle with the camera 58, the effect of extinguishing fires as soon as they are detected can be achieved. When the camera 58 detects a fire hazard, the PLC controller controls the drive wheel 53 to roll, so that the fire robot component 5 moves to the corresponding fire location. Then, the PLC controller controls the solenoid valve 705 to open, so that the extinguishing agent in the fire extinguisher bottle 7 is diverted to the rubber hose nozzle through the nozzle 701 and the connecting tube 704, and finally sprayed directly at the fire point through the rubber hose nozzle.
[0093] The fire extinguishing component is installed on the upper rear part of the mobile base 51 using a quick-release fixing component 6. The quick-release fixing component 6 fixes the fire extinguishing component by pressing down and tightening the limit.
[0094] The fire extinguishing assembly includes a fire extinguisher bottle 7, and the upper rear part of the movable base 51 is provided with a placement slot 511 for placing the fire extinguisher bottle 7;
[0095] The quick-release fixing assembly 6 includes vertical rods 61 set on the top of both sides of the placement slot 511, a top plate 62 connected to the top of the two sets of vertical rods 61, a sleeve seat 64 sleeved on the vertical rods 61, an arc-shaped limiting seat 71 fixed to the inner end of the sleeve seat 64 by a connecting arm 67, and an arc-shaped clamp plate 68 slidably connected to the lower inner side of the arc-shaped limiting seat 71.
[0096] A second spring 63 is also sleeved on the vertical rod 61, located between the top plate 62 and the sleeve seat 64. An adjusting internal threaded cylinder 65 is screwed onto the vertical rod 61, and the sleeve seat 64 is supported on the top of the adjusting internal threaded cylinder 65.
[0097] The lower inner side of the arc-shaped limiting seat 71 is provided with an arc-shaped groove 72 for sliding the arc-shaped clamp plate 68. The upper end of the arc-shaped clamp plate 68 is provided with a stud 70. The top of the stud 70 extends through the arc-shaped through groove 69 at the top of the arc-shaped groove 72 and is screwed with a fixing nut 66.
[0098] The inner diameters of the arc-shaped clamp plate 68 and the arc-shaped limiting seat 71 are the same.
[0099] The sleeve seat 64 slides along the vertical rod 61, and with the elastic force of the second spring 63, it can quickly press down and fix the top of the fire extinguisher bottle 7. The adjustable internal threaded sleeve 65 can be adapted to fire extinguisher bottles 7 of different heights.
[0100] The arc-shaped clamp plate 68 and the arc-shaped limiting seat 71 are locked together by the stud 70 and the fixing nut 66. The cooperation between the arc-shaped groove 72 and the arc-shaped through groove 69 allows for fine adjustment of the clamp angle, ensuring a stable clamping of fire extinguisher bottles 7 of different diameters (compatible with common 5-10L fire extinguishers).
[0101] When the fire extinguisher bottle 7 is pushed into the placement slot 511 and the top neck of the fire extinguisher bottle 7 is pressed against the inner wall of the arc-shaped limiting seat 71, the arc-shaped clamp plate 68 is driven by the stud 70 to slide out from the arc-shaped groove 72 until the arc-shaped clamp plate 68 is locked at the top neck of the fire extinguisher bottle 7, and then the fixing nut 66 is tightened.
[0102] The fire extinguishing component 7 adopts a modular design, which allows for convenient replacement during routine maintenance by quickly disassembling and assembling component 6 (a single person can complete the operation within 3 minutes), reducing operation and maintenance costs.
[0103] Quick assembly and disassembly steps for securing 6 pairs of fire extinguishing components (pressing down + tightening the limit):
[0104] Initial preparation:
[0105] Push the sleeve seat 64 upward to compress the second spring 63. The sleeve seat 64 drives the inner connecting arm 67, the arc-shaped limiting seat 71 and the arc-shaped clamp plate 68 to move upward simultaneously.
[0106] Place the fire extinguisher bottle 7 of the fire extinguishing assembly into the placement slot 511 of the movable base 51, ensuring that the central axis of the fire extinguisher bottle 7 is aligned with the center of the arc-shaped limiting seat 71 and the arc-shaped clamp plate 68.
[0107] Pre-fixing under pressure:
[0108] Release the sleeve seat 64, the second spring 63 presses down the sleeve seat 64, the sleeve seat 64 slides down along the vertical rod 61, causing the inner connecting arm 67 and the arc-shaped limiting seat 71 to move down synchronously until the inner wall of the arc-shaped limiting seat 71 fits against the outer side of the upper neck of the fire extinguisher bottle 7.
[0109] Rotate and adjust the internal threaded cylinder 65: Rotate the internal threaded cylinder 65 to move it up and down along the vertical rod 61 until the top of it hits the bottom of the sleeve seat 64. The position of the sleeve seat 64 is locked by mechanical limit. This can complete the adjustment of the height of the sleeve seat 64, the connecting arm 67, the arc-shaped limit seat 71 and the arc-shaped clamp plate 68, so as to satisfy the downward pressure and fixation of the arc-shaped limit seat 71 and the arc-shaped clamp plate 68 on fire extinguisher bottles 7 of different heights.
[0110] Fastening limit (arc-shaped clamp plate 68 locking):
[0111] Sliding arc-shaped clamp plate 68: Push the arc-shaped clamp plate 68 along the arc-shaped groove 72 on the inner side of the arc-shaped limiting seat 71 toward the fire extinguisher bottle 7, so that its inner wall fits tightly against the outer side of the top neck of the fire extinguisher bottle 7 (the inner diameter of the arc-shaped clamp plate 68 is the same as that of the arc-shaped limiting seat 71 to ensure a tight fit).
[0112] Locking and fixing nut 66: After the stud 70 at the upper end of the arc-shaped clamp plate 68 slides along the arc-shaped through groove 69 to the corresponding position, the fixing nut 66 is screwed into the top of the stud 70 and tightened. The movement of the arc-shaped clamp plate 68 is restricted by the cooperation between the stud and the arc-shaped through groove, so as to achieve all-round fastening of the fire extinguisher bottle 7.
[0113] Disassembly steps:
[0114] Simply push the sleeve seat 64 upwards to compress the second spring 63. The sleeve seat 64 then moves the inner connecting arm 67, the arc-shaped limiting seat 71, and the arc-shaped clamp plate 68 upwards simultaneously, causing the arc-shaped limiting seat 71 and the arc-shaped clamp plate 68 to gradually disengage from the top bottleneck of the fire extinguisher bottle 7. At this point, the fire extinguisher bottle 7 of the fire extinguishing assembly can be directly removed. This is because the outer diameter at the top bottleneck of the fire extinguisher bottle 7 gradually decreases (e.g., ...). Figure 14 As shown), when removing the fire extinguisher bottle 7, the top neck can be directly removed through the gap between the two sets of arc-shaped clamp plates 68.
[0115] The advantages of this fixing method:
[0116] Quick assembly and disassembly improves maintenance efficiency:
[0117] No complicated tools are needed; a single person can replace fire extinguisher bottle 7 in 30 seconds, solving the tedious problem of traditional bolt fixing requiring individual disassembly (traditional method takes 2-3 minutes);
[0118] It is compatible with different specifications of fire extinguishing components: by adjusting the height of the internal threaded cylinder 65 and the position of the arc-shaped clamp plate 68, it can be compatible with fire extinguisher bottles 7 with a diameter difference of ±20mm, which has strong versatility.
[0119] Double fixing ensures stable operation:
[0120] The downward pre-fixation and the arc-shaped clamp fastening form a "two-point limit": the arc-shaped limit seat 71 restricts the radial sway of the fire extinguisher bottle 7, and the arc-shaped clamp plate 68 prevents its axial movement. When the robot moves or the roof vibrates (such as when the wind is blowing), the fixing stability is improved.
[0121] The elastic pressure of the second spring 63 can buffer vibration and impact, preventing wear or leakage of the fire extinguisher bottle 7 due to rigid contact.
[0122] In summary, the quick-release fixing component 6, through a composite fixing method of "elastic downward pressure + arc-shaped limiting", ensures stable installation of the fire extinguishing component while significantly improving the efficiency of disassembly and assembly and the versatility of the equipment. It is especially suitable for the high-frequency maintenance needs of fire extinguishing equipment in rooftop photovoltaic scenarios.
[0123] Specifically, during use, the track 2 is fixed to the roof 1 between adjacent photovoltaic panels 4 by the quick-clamping component 3;
[0124] Press the bottom of the track 2 into the U-shaped limiting seat 36, squeeze the pressure plate 37 to make the lifting seat 34 move down, and drive the horizontal clamping block 35 into the track slot 201 through the cooperation of the inclined groove 39 and the pin 40, thus completing the quick fixation of the track 2.
[0125] The mobile seat 51 of the fire-fighting robot component 5 slides along the track 2 driven by the rollers 52, and the drive wheel 53 is supported on the roof 1 and provides power, enabling the robot to move horizontally between the photovoltaic panel arrays.
[0126] The rotatable camera assembly at the front of the mobile base 51 is responsible for real-time monitoring: the servo motor drives the rotating shaft 55 to rotate, which in turn drives the camera 58 to rotate horizontally; the camera 58 is connected to the rotating shaft 55 via the connecting base 57 to achieve pitch angle adjustment, and the locking nut 56 can fix the adjusted angle.
[0127] Camera 58 captures the surface temperature and abnormal light spots of photovoltaic panel 4, and uses image recognition technology to achieve early warning of fire hazards.
[0128] When a fire is detected, the central control system (PLC controller) triggers the fire extinguishing components: the solenoid valve 705 opens, and the extinguishing agent in the fire extinguisher bottle 7 is diverted through the nozzle 701 and connecting tube 704 to the connecting pipes on both sides 702, and finally sprayed towards the fire point through the nozzle 703;
[0129] The fire extinguishing component is connected to the mobile base 51 via the quick-release fixing component 6, which enables the quick disassembly, replacement and fixing of the fire extinguishing component. It also prevents the fire extinguishing component from falling off the mobile base 51 when the fire extinguishing agent is sprayed, ensuring stable delivery of the fire extinguishing agent. The robot can also move to the fire location to extinguish the fire accurately.
[0130] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
