Description

Technical Field

[0001] This invention belongs to the field of substation equipment technology, specifically relating to a multifunctional new energy box-type substation. Background Technology

[0002] Multifunctional new energy prefabricated substations are integrated power equipment mainly used in new energy power generation fields such as photovoltaic, wind power, and energy storage. Their core function is to step up the voltage of the power output from power generation units such as solar panels, wind turbines, and energy storage batteries to meet the voltage requirements for grid connection, thereby realizing long-distance and efficient power transmission. In recent years, a large number of large-scale new energy power generation stations have been built in remote areas of Northwest China with abundant wind and solar resources. These power stations are usually located in mountainous areas or large areas of flat Gobi desert, providing favorable conditions for the large-scale development of new energy.

[0003] However, the specific site selection of such new energy power plants also brings many practical challenges. On the one hand, the power plants are mostly far from urban areas, resulting in long commutes for maintenance personnel and low equipment maintenance efficiency. At the same time, most power plant areas lack surface water resources, leading to tight supplies of daily water and equipment cooling water, further increasing the difficulty of operation and maintenance. On the other hand, the installation environment of prefabricated substations is mostly on mountaintops or open, flat areas, lacking vegetation cover. During the hot summer and autumn seasons, strong direct sunlight causes the metal casing to absorb a large amount of heat radiation, resulting in a sharp rise in internal equipment temperature that is difficult to control effectively, seriously affecting the operational stability and service life of electrical components. In addition, if the heat generated by the transformers in the substation cannot be dissipated in time, it will also exacerbate the temperature rise of the equipment, and traditional heat dissipation methods are insufficient to meet the heat dissipation requirements in complex environments.

[0004] Based on the above problems, this application proposes a multifunctional new energy prefabricated substation to improve these problems. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional new energy box-type substation that can change from an initial state to a collection state by driving a motor during rainy weather, collect rainwater through a storage tank, and achieve efficient absorption and transfer of heat inside the casing by utilizing the heat capacity of the water. It can also effectively reduce the overall temperature rise caused by solar thermal radiation.

[0006] The specific technical solution adopted by this invention is as follows:

[0008] Multiple drive units are respectively assembled at the four end corners of the top of the storage tank, and the first flow guide cover is connected to the drive units;

[0009] A limiting part is mounted on the upper end of the storage tank, and the rain sensor is connected to the limiting part;

[0010] In the initial state, the storage tank, the first guide cover, and the limiting part constitute a closed storage chamber; when the rain sensor detects the rain signal, the driving part drives the first guide cover to operate, and the storage tank and the first guide cover constitute an open collection chamber.

[0011] In a preferred embodiment, a hollow insulation layer is provided in the side wall of the shell, and the hollow insulation layer and the storage tank are interconnected, so that rainwater collected inside the storage tank can flow into the hollow insulation layer.

[0012] In a preferred embodiment, the drive unit includes a drive motor, a transmission arm, a transmission sleeve, and a driven arm. The drive motor is fixed to the upper end of the storage tank, the transmission arm is fixed to the output end of the drive motor, the transmission sleeve is slidably connected to the upper end of the outer side of the transmission arm, and the driven arm is slidably connected to the upper end of the inner side of the transmission sleeve. Furthermore, the storage tank, the transmission arm, the first guide cover, and the driven arm are all rotatably connected.

[0013] In a preferred embodiment, a first flange plate is fixed to the top of the storage tank, a second flange plate is fixed inside the first guide cover plate, and pins are provided at the ends of the drive arm and the driven arm that are far apart from each other. The drive arm and the first flange plate, as well as the driven arm and the second flange plate, are rotatably connected by pins.

[0014] In a preferred embodiment, the limiting part includes multiple electric cylinders, multiple base plates, and a limiting plate. The multiple electric cylinders are respectively fixed to both ends of the top of the storage tank, the multiple base plates are respectively fixed to the output ends of the multiple electric cylinders, the limiting plate is fixed to the upper end of the multiple base plates, and the rain sensor and the limiting plate are fixedly connected.

[0015] In a preferred embodiment, a second guide cover is slidably connected inside the first guide cover, and a third guide cover is slidably connected inside the second guide cover. A plurality of transmission telescopic parts are assembled between the storage tank and the third guide cover, and the transmission telescopic parts are connected to the drive part.

[0016] In a preferred embodiment, T-shaped guide rods are fixed to both ends of the first guide cover and both ends of the second guide cover. Guide slots are provided at both ends of the second and third guide covers, and the T-shaped guide rods and guide slots are compatible with each other.

[0017] In a preferred embodiment, both the second and third guide plates have U-shaped clearance grooves inside, and the U-shaped clearance grooves are adapted to the second flange plate.

[0018] In a preferred embodiment, the telescopic transmission unit includes a third flange plate, a fourth flange plate, a transmission shaft, a transmission block, and multiple connecting rod arms. The third flange plate and the fourth flange plate are both fixed to the upper end of the storage tank. The transmission shaft is rotatably connected to the inside of the third flange plate via ball bearings, and the transmission shaft and the drive motor are fixedly connected via pins inside the transmission arm. The transmission shaft and the transmission arm can rotate synchronously. The transmission block is fixed to the outer end of the transmission shaft away from the drive motor.

The two uppermost connecting rod arms are rotatably connected to the third guide cover plate. The transmission block can drive the telescopic linkage mechanism to change from a retracted state to an extended state.

[0019] The technical effects achieved by this invention are as follows:

[0020] After obtaining rainfall signals through a rain sensor, the present invention drives a motor to rotate the first guide cover, changing the device from the initial state to the collection state. The rainwater is collected and guided into the storage tank through the first guide cover, and the rainwater is stored in the storage tank, which alleviates the water shortage in remote areas of substations and reduces the difficulty and cost of operation and maintenance.

[0021] This invention utilizes highly thermally conductive materials to rapidly absorb the heat generated by the transformer operating inside the casing and transfer it to rainwater stored in the storage tank. By leveraging the heat capacity of the water, it achieves efficient absorption and transfer of heat from inside the casing, thereby significantly improving the operating environment of the equipment inside the casing. Simultaneously, by absorbing heat from the casing and the first guide cover plate through rainwater, it effectively reduces the overall temperature rise caused by solar thermal radiation. This not only solves the heat dissipation problem in high-temperature environments but also innovatively utilizes rainwater resources for cooling, providing a highly efficient and economical solution for the operation and maintenance of new energy power plants in remote and water-scarce areas.

[0022] After acquiring rainfall signals through a rain sensor, the present invention drives a motor to rotate the first guide cover and the transmission telescopic part synchronously, so that the second and third guide covers move relative to the first guide cover. This allows the device to collect rainwater more efficiently during rainfall, especially when the rainfall is light, and can collect more rainwater in the same amount of time.

[0042] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0044] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0045] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth. Example

[0046] Please see the appendix Figure 1 As shown, this is the first embodiment of the present invention. This embodiment provides a multifunctional new energy box-type substation, including a housing 10. A transformer assembly is installed inside the housing 10. A storage tank 11 is fixed on the top of the housing 10. The storage tank 11 has a concave structure. Both sides of the storage tank 11 are rotatably connected to a first guide cover 12 via hinges. A rainwater sensor 13 is also installed at the upper end of the storage tank 11. The substation also includes:

[0047] Multiple drive units 20 are respectively assembled at the four end corners of the top of the storage tank 11, and the first guide cover plate 12 is connected to the drive units 20.

[0048] The limiting part 30 is mounted on the upper end of the storage tank 11, and the rain sensor 13 is connected to the limiting part 30.

[0049] In the initial state, the storage tank 11 and the first guide cover 12 are in contact with each other, and the storage tank 11, the first guide cover 12 and the limiting part 30 form a closed storage chamber, and the limiting part 30 limits the first guide cover 12. When the rain sensor 13 detects the rain signal, the driving part 20 drives the first guide cover 12 to operate, and the storage tank 11 and the first guide cover 12 form an open collection chamber. At this time, the device is in the collection state.

[0050] Here, the storage tank 11 is made of a high thermal conductivity material, the surface of the first flow guide cover 12 is coated with a mirror coating, and the rain sensor 13 is a capacitive rain sensor.

[0051] In this embodiment, during rainfall, rainwater drips onto the sensing end of the rainwater sensor 13. Upon sensing the rainfall, the limiting part 30 operates, increasing its overall height and releasing its restriction on the first guide cover 12. After the restriction is released, the driving part 20 operates, causing the first guide cover 12 to rotate, thus separating the storage tank 11 and the first guide cover 12. The closed storage chamber transforms into an open collection chamber, allowing rainwater to drip onto the surface of the first guide cover 12 and slide down into the storage tank 11, thereby collecting the rainwater. When the rainfall stops, the rainwater on the surface of the rainwater sensor 13 remains relatively still and no longer changes. The driving part 20 reverses its rotation, causing the first guide cover 12 to reset, allowing the storage tank 11 and the first guide cover 12 to re-adhere to each other. After the operation of part 20 is completed, the limiting part 30 reverses to reset. After the limiting part 30 is reset, the open collection chamber is transformed into a closed storage chamber. The collected rainwater is stored in the storage chamber. When the internal temperature of the shell 10 is high, the heat emitted by the transformer inside the shell 10 is quickly absorbed by the high thermal conductivity material and conducted to the rainwater stored in the storage tank 11. The heat capacity of the water is used to achieve efficient absorption and transfer of heat inside the shell 10, thereby significantly improving the operating environment of the equipment inside the shell 10. At the same time, by absorbing the heat of the shell 10 and the first guide cover 12 through the rainwater, the overall temperature rise caused by solar thermal radiation can be effectively reduced. This not only solves the heat dissipation problem in high-temperature environments, but also innovatively utilizes rainwater resources for cooling, providing a highly efficient and economical solution for the operation and maintenance of new energy power plants in remote and water-scarce areas.

[0052] It should be noted that the working principle of the rain sensor 13 is mainly based on the detection of changes in conductivity. When rainwater comes into contact with the surface of the rain sensor 13, it changes its conductive path, thereby causing a change in resistance or conductivity. This change is then converted from an analog signal to a digital signal so that electronic equipment can read and analyze it. Specifically, the rain sensor 13 is a mature existing application, and its specific working principle can be found in existing technologies. Further details will not be provided here.

[0053] In a preferred embodiment, a hollow heat insulation layer is provided in the side wall of the housing 10, and the hollow heat insulation layer and the storage tank 11 are interconnected, so that rainwater collected inside the storage tank 11 can flow into the hollow heat insulation layer.

[0054] It should be noted that the hollow insulation layer meets the IP68 waterproof rating.

[0055] Secondly, please refer to it again. Figures 2 to 3 The drive unit 20 includes a drive motor 21, a transmission arm 22, a transmission sleeve 23, and a driven arm 24. The drive motor 21 is fixed to the upper end of the storage tank 11, the transmission arm 22 is fixed to the output end of the drive motor 21, the transmission sleeve 23 is slidably connected to the upper end of the outer side of the transmission arm 22, and the driven arm 24 is slidably connected to the upper end of the inner side of the transmission sleeve 23. The storage tank 11 and the transmission arm 22, as well as the first guide cover plate 12 and the driven arm 24, are all rotatably connected.

[0056] It should be noted that the drive motor 21 has self-locking and waterproof features.

[0057] Furthermore, a first flange plate 25 is fixed to the top of the storage tank 11, a second flange plate 26 is fixed inside the first guide cover plate 12, and pins are provided at the ends of the drive arm 22 and the driven arm 24 that are far apart from each other. The drive arm 22 and the first flange plate 25, as well as the driven arm 24 and the second flange plate 26, are rotatably connected by pins.

[0058] In this embodiment, during rainy weather, after the rain sensor 13 detects rainfall, the limiting part 30 operates, its overall height increases, and it releases the restriction on the first guide cover 12. After the restriction is released, the drive motor 21 operates. Since the drive motor 21 and the transmission arm 22 are fixedly connected, and the transmission arm 22 and the transmission sleeve 23, as well as the transmission sleeve 23 and the driven arm 24 are all slidably connected, the drive motor 21 electrically drives the arm 22, the transmission sleeve 23, and the driven arm 24 to rotate synchronously. This is achieved through the driven arm 24 and the first guide cover. The fixed connection between 12 allows the driven boom 24 to rotate the first guide cover 12, thereby causing the first guide cover 12 and the storage tank 11 to no longer be in contact. The device changes from the initial state to the collection state. Rainwater falling onto the surface of the first guide cover 12 can be guided into the storage tank 11, thus collecting the rainwater. When the rainfall stops, the drive motor 21 rotates in the opposite direction, driving the first guide cover 12 to reset, causing the storage tank 11 and the first guide cover 12 to be in contact again. The device changes from the collection state to the initial state (as shown in the image). Figure 11 (As shown).

[0059] Secondly, please refer to it again. Figure 4 The limiting part 30 includes multiple electric cylinders 31, multiple base plates 32 and a limiting plate 33. The multiple electric cylinders 31 are respectively fixed at both ends of the top of the storage tank 11, the multiple base plates 32 are respectively fixed at the output ends of the multiple electric cylinders 31, the limiting plate 33 is fixed at the upper end of the multiple base plates 32, and the rain sensor 13 and the limiting plate 33 are fixedly connected.

[0060] It should be noted that when the device is in its initial state, the limiting plate 33 and the first guide cover 12 are in contact, and the limiting plate 33 limits the first guide cover 12.

[0061] In this embodiment, when rainy weather occurs, the rain sensor 13 detects rainfall and the electric cylinder 31 is activated. Since the electric cylinder 31 and the base plate 32, as well as the base plate 32 and the limiting plate 33, are all fixedly connected, the electric cylinder 31 drives the base plate 32 and the limiting plate 33 to move upward synchronously. When the limiting plate 33 and the first guide cover 12 are separated, the limiting plate 33 releases its restriction on the first guide cover 12.

[0062] In one specific embodiment, the multi-functional prefabricated substation with the above-described structural design, in addition to having conventional power transmission and transformation functions, can greatly improve the reliability of the entire unit's operation. It is expected to reduce the temperature rise of the electrical compartment by more than 10K, thereby reducing the thermal aging rate of internal electrical components and improving the service life of the entire equipment.

[0063] In another specific embodiment, with an area of ​​15m 2 Taking prefabricated substations as an example, this structure and effective rain-receiving area can reach 25-30m².2 A 100MW new energy power plant, equipped with 30 modified units, can meet an annual water demand exceeding 200m³ in the Northwest region, where annual precipitation is 300-400mm. 3 Since many new energy power stations are designed in remote areas, the travel time to residential areas is long, the traffic conditions are unstable, and the water supply generally depends on vehicles from nearby cities, resulting in high transportation costs and difficulty in ensuring timeliness. Adopting this type of product design can greatly alleviate the water shortage problem for power station operation and maintenance personnel, reduce the risk of water shortage at the power station due to severe weather, improve the self-sufficiency of on-site personnel, and reduce dependence on external factors. Example

[0064] This embodiment is an optimization based on Embodiment 1, specifically:

[0065] Please refer to it again. Figures 5 to 7 The first guide cover 12 is slidably connected to the second guide cover 14, and the second guide cover 14 is slidably connected to the third guide cover 15. A plurality of transmission telescopic parts 40 are assembled between the storage tank 11 and the third guide cover 15, and the transmission telescopic parts 40 are connected to the drive part 20. The transmission telescopic parts 40 are configured to drive the third guide cover 15 to slide away from the storage tank 11, and the drive motor 21 can drive the transmission telescopic parts 40 to operate synchronously.

[0066] For further details, please refer to Figure 9 As shown, T-shaped guide rods 16 are fixed at both ends of the first guide cover plate 12 and both ends of the second guide cover plate 14. Guide grooves 17 are opened at both ends of the second guide cover plate 14 and the third guide cover plate 15, and the T-shaped guide rods 16 and guide grooves 17 are compatible.

[0067] In this embodiment, during rainy weather, rainwater drips onto the sensing end of the rainwater sensor 13. After the rainwater sensor 13 detects the rainfall, the limiting part 30 operates, increasing its overall height and releasing the limiting effect on the first guide cover 12. After the limiting effect is released, the drive motor 21 operates, driving the first guide cover 12 to rotate and simultaneously driving the transmission telescopic part 40 to rotate. The transmission telescopic part 40 drives the third guide cover 15 to slide away from the storage tank 11. When the third guide cover 15 moves to its maximum distance relative to the second guide cover 14, the third guide cover 15... The second guide cover 14 is moved so that it slides relative to the first guide cover 12. When the device changes from the initial state to the collection state, the second guide cover 14 and the third guide cover 15 move to the maximum distance relative to the first guide cover 12. At this time, the area for guiding and collecting rainwater is larger than the area for guiding and collecting rainwater in Embodiment 1. Through the cooperation of the first guide cover 12, the second guide cover 14 and the third guide cover 15, rainwater can be collected more efficiently, especially when the rainfall is light. In the same amount of rainfall time, more rainwater can be collected.

[0068] Please refer to it again. Figure 8 Both the second guide cover plate 14 and the third guide cover plate 15 have U-shaped clearance grooves 18 inside, and the U-shaped clearance grooves 18 are adapted to the second flange plate 26.

[0069] In this embodiment, the U-shaped clearance groove 18 can prevent collisions between the second guide cover plate 14 and the second flange plate 26, as well as the third guide cover plate 15 and the second flange plate 26, when the device is in its initial state, so that the device can operate better.

[0070] Please refer again to Figure 10. The transmission telescopic part 40 includes a third flange plate 41, a fourth flange plate 42, a transmission shaft 43, a transmission block 44, and multiple connecting rod swing arms 45. The third flange plate 41 and the fourth flange plate 42 are both fixed to the upper end of the storage tank 11. The transmission shaft 43 is rotatably connected to the inside of the third flange plate 41 through ball bearings. The transmission shaft 43 and the drive motor 21 are fixedly connected through a pin inside the transmission arm 22. The transmission shaft 43 and the transmission arm 22 can rotate synchronously. The transmission block 44 is fixed to the outside of the transmission shaft 43 at the end away from the drive motor 21. The multiple connecting rod swing arms 45 are rotatably connected to each other to form a telescopic linkage mechanism. The two uppermost connecting rod swing arms 45 are rotatably connected to the fourth flange plate 42, and the one lowermost connecting rod swing arm 45 is adapted to the transmission block 44. The two uppermost connecting rod swing arms 45 are rotatably connected to the third guide cover plate 15. The transmission block 44 can drive the telescopic linkage mechanism to change from a retracted state to an extended state.

[0071] It should be noted that when the device is in the initial state, the telescopic linkage mechanism is in the retracted state; when the device changes to the collecting state, the telescopic linkage mechanism simultaneously changes to the extended state.

[0072] In this embodiment, during rainy weather, the limiting part 30 operates to release the limiting of the first guide cover 12. After the limiting is released, the drive motor 21 operates, driving the first guide cover 12, the transmission arm 22, and the transmission shaft 43 to rotate synchronously. Through the fixed connection between the transmission shaft 43 and the transmission block 44, the transmission shaft 43 drives the transmission block 44 to rotate. When the transmission block 44 contacts the lowest connecting arm 45, the transmission block 44 drives the connecting arm 45 to rotate, thereby changing the telescopic linkage mechanism from a retracted state to an extended state, thus enabling telescopic... The linkage mechanism drives the third guide cover 15 to move relative to the second guide cover 14. When the third guide cover 15 moves to the maximum distance relative to the second guide cover 14, the third guide cover 15 drives the second guide cover 14 to move synchronously relative to the first guide cover 12. When the device changes to the collection state, the cooperation of the first guide cover 12, the second guide cover 14 and the third guide cover 15 can effectively increase the rainwater collection area and collect rainwater more efficiently, especially when the rainfall is light. In the same amount of rainfall time, more rainwater can be collected. Example

[0073] This embodiment is a further optimization based on Embodiment 2, specifically:

[0074] A sealed storage tank (not shown in the figure) is fixed at the bottom of the housing 10. A liquid inlet is provided at the upper end of the storage tank. A first liquid level sensor (not shown in the figure) is fixed inside the storage tank. The first liquid level sensor is configured to monitor the liquid level inside the storage tank. A liquid pump (not shown in the figure) is installed inside the housing 10. A liquid outlet is provided at the lower end of the storage tank 11. A second liquid level sensor (not shown in the figure) is fixed inside the storage tank 11. The second liquid level sensor is configured to monitor the liquid level inside the storage tank 11. The output end of the liquid pump and the liquid inlet, as well as the input end of the liquid pump and the liquid outlet, are all connected by pipelines.

[0075] It should be noted that a control circuit board is also used in conjunction with the device. The control circuit board has an integrated control program. The control program can set the upper limit of the storage of the first liquid level sensor, and can also set the upper limit and lower limit of the storage of the second liquid level sensor.

[0076] In this embodiment, during rainy weather, the drive unit 20 and the limiting unit 30 operate. The drive unit 20 drives the first guide cover 12 to rotate, causing the device to switch to a collection state. Rainwater is guided by the first guide cover 12, the second guide cover 14, and the third guide cover 15 and collected into the storage tank 11. When the liquid level inside the storage tank does not reach the upper limit of storage, the pump starts to transport the rainwater inside the storage tank 11 into the storage tank, preventing the rainwater from evaporating inside the storage tank 11. When there is no rainfall in the surrounding environment and the liquid level inside the storage tank 11 reaches the lower limit of storage, the pump reverses its operation to transport the rainwater inside the storage tank into the storage tank 11. When there is rainfall in the environment and the liquid level inside the storage tank reaches the upper limit of storage, and the liquid level inside the storage tank 11 also reaches the upper limit of heat dissipation, the drive unit 20 and the limiting unit 30 operate, causing the device to switch from the collection state to the initial state. Example

[0077] This embodiment is a further optimization based on Embodiment 3, specifically:

[0078] Using a single device as a decentralized rainwater collection unit, each rainwater collection unit is tightly and reliably connected through a matching pipeline system. The excess rainwater collected is then gathered into a sedimentation tank with a filtration system for daily use by the station staff, effectively solving the problem of water shortage in remote stations.

[0079] The working principle of this invention is as follows:

[0080] During rainfall, after the rain sensor 13 detects rainfall, the electric cylinder 31 operates, causing the limiting plate 33 to move and release its restriction on the first guide cover 12. Once released, the drive motor 21 operates, causing the first guide cover 12, the transmission arm 22, and the driven arm 24 to rotate synchronously. This causes the storage tank 11 and the first guide cover 12 to no longer be in contact, transforming the closed storage chamber into an open collection chamber. Rainwater drips onto the surface of the first guide cover 12 and slides down its surface into the storage tank 11, thus collecting the rainwater. When the rainfall stops, the rainwater on the surface of the rain sensor 13 remains relatively still and no longer changes. The drive motor 21 then reverses its rotation, causing the first guide cover 12 to retract. The storage tank 11 and the first guide cover 12 are brought into contact again. After the drive motor 21 finishes running, the electric cylinder 31 rotates in the reverse direction to reset. After the electric cylinder 31 is reset, the open collection chamber is transformed into a closed storage chamber. The collected rainwater is stored in the storage chamber. When the internal temperature of the shell 10 is high, the rainwater collected in the storage tank 11 absorbs the heat inside the shell 10 because water has a higher specific heat capacity than air, thereby cooling the inside of the shell 10. At the same time, when the external ambient temperature is high, the setting of the first guide cover 12 can reduce the area exposed to direct sunlight. In addition, the rainwater collected in the storage tank 11 can absorb the heat on the surface of the shell 10 and the first guide cover 12, which can effectively reduce the temperature rise of the shell caused by strong sunlight.

[0081] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
