Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of supporting facilities of a hydropower station, in particular to a dam floating object cleaning device and a hydropower station. BACKGROUND

[0002] Hydropower is a technology that converts the potential energy and kinetic energy of water in nature into electric energy. A common hydropower facility is a dam-type hydropower station, which forms a reservoir by building a dam on a river, and generates electricity by using the water in the reservoir through a water turbine. Among them, the dam is used to form a reservoir, regulate water flow, and increase the water head; the reservoir is used to store and regulate water volume to meet the power generation demand; the generator set in the dam includes a water turbine, a generator and a power transmission system, the water turbine converts the kinetic energy of water flow into mechanical energy, and then the mechanical energy is converted into electric energy through the generator, and finally the electric energy generated by the power station is transmitted to the power grid through the power transmission system to form a complete power generation system.

[0003] The water body in nature is easily affected by weather and environment, especially in the case of flood discharge or sudden weather, a large amount of floating objects entering the reservoir area will cause harm to the hydraulic structure and the generator set, and a large amount of floating objects accumulated downstream also pose a great risk. Therefore, it is necessary to set up a water body floating object interception and treatment system in the hydropower facility.

[0004] Although the prior art discloses a reservoir pollution blocking system and a liquid surface floating object separation device for floating object collection and separation, it mainly directly intercepts and cleans floating objects, relies on manual or mechanical equipment to clean at the dam inlet, and although it has certain collection and cleaning capacity, it is difficult for the mechanical equipment to clean under complex flood discharge conditions, and it is also difficult to classify and process the floating objects, which will increase the subsequent processing procedures, resulting in an increase in cleaning and maintenance costs.

[0005] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present application, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art. CONTENT OF THE UTILITY MODEL

[0006] The purpose of the present application is to overcome the shortcomings of the prior art, and to provide a dam floating object cleaning device and a hydropower station, which can comprehensively process the dam floating objects through the setting of the interception and guidance assembly and the classification and cleaning assembly, improve the processing efficiency of the floating objects in the water body, and reduce the cost of the dam in terms of floating object processing and processing component maintenance.

[0007] According to an aspect of the present application, a dam floating object cleaning device is provided, which is arranged in a dam of a hydropower station, the dam comprising a dam body, the dam floating object cleaning device mainly comprising: an intercepting and guiding assembly and a sorting and cleaning assembly, the intercepting and guiding assembly comprising an intercepting mechanism movably connected with the dam body and a guiding channel located at one end of the intercepting mechanism, the guiding channel being arranged at one side of the dam body and extending into the interior of the dam body; the sorting and cleaning assembly comprising a first cleaning region and a second cleaning region, the first cleaning region and the second cleaning region being arranged in the guiding channel in sequence, the first cleaning region being close to the entrance of the guiding channel; wherein the first cleaning region is used for processing large floating objects, and comprises a mechanical arm and a first conveying mechanism, the mechanical arm being fixed to the inner wall of the guiding channel, the activity range of the mechanical arm being at least partially located in the conveying range of the first conveying mechanism; the second cleaning region is used for processing small floating objects, and comprises a second conveying mechanism fixed to the inner wall of the guiding channel.

[0008] According to some embodiments of the present application, the mechanical arm and the first conveying mechanism can slide in the vertical direction of the guiding channel; and / or the second conveying mechanism slides in the vertical direction of the guiding channel.

[0009] According to some embodiments of the present application, the mechanical arm and the first conveying mechanism are respectively located at opposite sides of the guiding channel.

[0010] According to some embodiments of the present application, the second conveying mechanism is located in the guiding channel, and the conveying direction coincides with the extension direction of the guiding channel.

[0011] According to some embodiments of the present application, a blocking region is arranged between the first cleaning region and the second cleaning region, the blocking region being used for forming the interception of the large floating objects.

[0012] According to some embodiments of the present application, the blocking region comprises one or more intercepting nets arranged along the extension direction of the guiding channel.

[0013] According to some embodiments of the present application, the covering height of the intercepting net is greater than the highest designed water level in the guiding channel, and the shape of the intercepting net is adapted to the shape of the water body along the vertical section of the extension direction of the guiding channel when the guiding channel is at the highest designed water level.

[0014] According to some embodiments of the present application, the intercepting and guiding assembly comprises a rotating mechanism arranged perpendicularly to the horizontal plane, the rotating mechanism being rotatably connected with the dam body, one end of the intercepting mechanism being connected with the rotating mechanism.

[0015] According to some embodiments of the present application, a first floating mechanism is arranged between the rotating mechanism and the dam body to adjust the position cooperation between the rotating mechanism and the water body; and / or a second floating mechanism is arranged between the intercepting mechanism and the rotating mechanism to adjust the position cooperation between the intercepting mechanism and the water body.

[0016] According to an aspect of the present application, a hydropower station is provided, which comprises a dam body, a water inlet, and a dam floating debris cleaning device as described above, and the intercepting and guiding assembly of the dam floating debris cleaning device is located on one side of the dam body close to the water inlet.

[0017] The dam floating debris cleaning device and the hydropower station provided by the present application mainly comprise an intercepting and guiding assembly and a classification and cleaning assembly. The intercepting and guiding assembly comprises an intercepting mechanism movably connected to the dam body and a guiding channel located at one end of the intercepting mechanism. The guiding channel is arranged on one side of the dam body and extends into the interior of the dam body. The classification and cleaning assembly comprises a first cleaning region and a second cleaning region. The first cleaning region and the second cleaning region are arranged in the guiding channel in sequence, and the first cleaning region is close to the entrance of the guiding channel. The first cleaning region is used for processing large floating debris, and comprises a mechanical arm and a first conveying mechanism. The mechanical arm is fixed to the inner wall of the guiding channel, and the movement range of the mechanical arm is at least partially located within the conveying range of the first conveying mechanism. The second cleaning region is used for processing small floating debris, and comprises a second conveying mechanism fixed to the inner wall of the guiding channel.

[0018] The floating debris is guided into the classification and cleaning assembly through the arrangement of the intercepting and guiding assembly, and the classification and cleaning assembly classifies the floating debris according to the size of the floating debris. The larger floating debris is sorted by the mechanical arm and conveyed by the first conveying mechanism. The mechanical arm can further classify the floating debris, such as dry wood, branches, large pieces, etc., and the floating debris is directly conveyed by the first conveying mechanism. The smaller floating debris is directly conveyed outward by the second conveying mechanism, so as to realize the classification and cleaning of the floating debris.

[0019] The above arrangement guides the floating debris, avoids direct cleaning on the dam, reduces the cleaning pressure of the cleaning equipment, and can cope with complex situations such as flood discharge. On the other hand, the floating debris is directly classified and processed, avoiding secondary classification and processing, and reducing the subsequent processing procedure.

[0020] The arrangement of the interception guide assembly not only avoids the influence of the floating objects on the hydraulic structure and the generator set, but also concentrates the floating objects into the guide channel for classification processing. The concentration of the floating objects not only reduces the number of cleaning devices that need to be arranged on the dam body, but also enables direct classification of the floating objects, significantly improves the cleaning speed of the cleaning equipment, and further improves the processing efficiency of the floating objects.

[0021] The reduction of the cleaning equipment and the cleaning pressure not only reduces the labor input, thereby reducing the equipment maintenance cost and labor cost input, but also is beneficial to reducing the risk of manual processing of floating objects in complex situations.

[0022] The classification processing of the floating objects and the separate outward conveying avoid the complicated procedures of transportation and then classification processing, and processing and then transportation, which not only improves the efficiency of the classification processing of the floating objects, but also avoids the high cost input caused by the complicated procedures.

[0023] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present application. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0032] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0033] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity, the description of a particular example will not necessarily be repeated in the description of each example. Furthermore, the present application can refer to a number of reference numerals in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and / or configurations discussed.

[0034] For the purpose of description, spatial relative terms, such as "inner", "outer", "inward", "outward", "lower", "bottom", "top", "upper", "front", "rear", and the like, can be used to describe the relative position relationship or movement of one element or feature to another element or feature as shown in the drawings. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over or reversed, or the orientation of the device is changed, the indication of the direction will also change accordingly, for example, the element described as "below" or "under" the other element or feature will be subsequently oriented as "above" or "over" the other element or feature. Therefore, the example term "under" can include both upward and downward positions. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0035] As Figures 1 to 5As shown, in the first aspect, in some exemplary embodiments of the present application, a dam floating object cleaning device is provided in a dam 10 of a hydropower station, the dam 10 comprising a dam body 11, and the dam floating object cleaning device mainly comprises an intercepting and guiding assembly 20 and a sorting and cleaning assembly 30.

[0036] The intercepting and guiding assembly 20 comprises an intercepting mechanism 21 movably connected with the dam body 11 and a guiding channel 22 located at one end of the intercepting mechanism 21, the guiding channel 22 being arranged at one side of the dam body 11 and extending into the interior of the dam body 11.

[0037] The sorting and cleaning assembly 30 comprises a first cleaning area 31 and a second cleaning area 32, the first cleaning area 31 and the second cleaning area 32 being arranged in the guiding channel 22 in sequence, and the first cleaning area 31 being close to the entrance of the guiding channel 22.

[0038] The first cleaning area 31 is used for processing large floating objects, and comprises a mechanical arm 311 and a first conveying mechanism 312, the mechanical arm 311 being fixed to the inner wall of the guiding channel 22, and the activity range of the mechanical arm 311 being at least partially located in the conveying range of the first conveying mechanism 312.

[0039] The second cleaning area 32 is used for processing small floating objects, and comprises a second conveying mechanism 321 fixed to the inner wall of the guiding channel 22.

[0040] In the above embodiment, the floating objects are guided into the sorting and cleaning assembly through the arrangement of the intercepting and guiding assembly, and the classification of the size of the floating objects is performed through the first cleaning area 31 and the second cleaning area 32 in the sorting and cleaning assembly. The larger floating objects are sorted by the mechanical arm 311 and conveyed by the first conveying mechanism 312, the mechanical arm 311 can further classify, for example, dry wood, branches, large pieces, etc., and directly conveyed by the first conveying mechanism 312. The smaller floating objects can be directly conveyed outward by the second conveying mechanism 321, thereby realizing the sorting and cleaning of the floating objects.

[0041] The above arrangement guides the floating objects, avoids direct cleaning on the dam 10, reduces the cleaning pressure of the cleaning equipment, and can cope with complex situations such as flood discharge. On the other hand, the floating objects are directly classified and processed, avoiding secondary classification and processing, and reducing the subsequent processing procedures.

[0042] The arrangement of the intercepting and guiding assembly 20 not only avoids the influence of the floating objects on the hydraulic structure and the generator set, but also concentrates the floating objects into the guiding channel 22 for classification and processing. The concentration of the floating objects not only reduces the number of cleaning devices that need to be arranged on the dam body 11, but also directly classifies the floating objects, significantly improves the cleaning speed of the cleaning equipment, and further improves the processing efficiency of the floating objects.

[0043] The reduction of the cleaning equipment and the reduction of the cleaning pressure can not only reduce the labor input, thereby reducing the equipment maintenance cost and the labor cost input, but also help to reduce the risk of manual handling of floating objects in complex situations.

[0044] The classification and processing of floating objects and the separate external delivery avoid the complicated procedures of transportation and then classification and processing, and transportation after processing, which not only improves the efficiency of floating object classification and processing, but also avoids the high cost input caused by complicated procedures.

[0045] In some exemplary embodiments of the present application, the intercepting mechanism 21 movably connected with the dam body 11 is used to adapt to different water levels on one side of the reservoir, so as to have targeted interception of floating objects. The intercepting mechanism 21 is only used for interception and guidance of floating objects, and the blocking net is separately arranged at the water inlet 12 of the dam 10. Such a setting makes the intercepting mechanism have higher flexibility and can increase the interception and guidance effect of floating objects.

[0046] As shown in Figure 3 In some exemplary embodiments of the present application, the mechanical arm 311 and the first conveying mechanism 312 can slide in the vertical direction of the guide channel 22. Such a setting is used to adapt to different water depths, so that the mechanical arm 311 and the first conveying mechanism 312 are more reliable in picking up and conveying floating objects.

[0047] It can be understood that the water depth of the reservoir will change with the change of the environment and the operation, so the water depth in the guide channel 22 is not completely the same. At this time, the mechanical arm 311 and the first conveying mechanism 312 are set to adapt to the water depth, so as to meet the requirements of different water depths.

[0048] In some exemplary embodiments of the present application, the second conveying mechanism 321 slides in the vertical direction of the guide channel 22. The setting principle in the present embodiment is the same as that of the mechanical arm 311 and the first conveying mechanism 312 described above, which will not be repeated here.

[0049] In some exemplary embodiments of the present application, the mechanical arm 311, the first conveying mechanism 312 and the second conveying mechanism 321 can slide in the vertical direction of the guide channel 22. Such a setting makes the transportation of floating objects in front and back adaptable.

[0050] As shown in Figure 3As shown, in some exemplary embodiments of the present application, the mechanical arm 311 and the first conveying mechanism 312 are respectively arranged on opposite sides of the guide channel 22. Such an arrangement makes the most of the space of the guide channel 22, reduces the interference, and facilitates the picking and cleaning of the floating objects in the guide channel 22.

[0051] In some exemplary embodiments of the present application, the mechanical arms 311 are arranged in sequence on an inner wall along the extending direction of the guide channel 22, so as to improve the processing efficiency of the floating objects.

[0052] Further, in this embodiment, a plurality of first conveying mechanisms 312 are arranged on the inner wall opposite to the mechanical arms 311 in the guide channel 22, so as to improve the conveying efficiency of the classified floating objects.

[0053] In some other exemplary embodiments of the present application, the mechanical arms 311 and the first conveying mechanisms 312 are arranged in one-to-one correspondence, and the positions of the mechanical arms 311 and the first conveying mechanisms 312 of an adjacent group are arranged in opposite directions along the extending direction of the guide channel 22, that is, the mechanical arms 311 and the first conveying mechanisms 312 are arranged alternately on a single inner wall. Such an arrangement can avoid the interference between the adjacent mechanical arms 311, increase the working range of the mechanical arms, and avoid dead angles.

[0054] As shown in FIG. 5, in some exemplary embodiments of the present application, the second conveying mechanism 321 is arranged in the guide channel 22, and the conveying direction coincides with the extending direction of the guide channel 22. Such an arrangement makes the water flow in the same direction as the arrangement direction of the second conveying mechanism 321, so as to realize the direct conveying of the floating objects into the second conveying mechanism 321, which is more convenient.

[0055] As shown in FIG. 4, in some exemplary embodiments of the present application, the first conveying mechanism 312 is a conveyor belt, and the conveyor belt is arranged obliquely, and the horizontal height of one end of the inner wall of the guide channel 22 close to the arrangement position of the conveyor belt is higher than that of the other end, that is, the conveyor belt is arranged obliquely, so as to convey the floating objects upward.

[0056] Further, in some exemplary embodiments of the present application, the conveyor belt is provided with a spacer plate perpendicular to the extending direction of the conveyor belt, which can prevent the wet floating objects from sliding down the conveyor belt, reduce the limitation on the oblique angle of the conveyor belt, reduce the occupied distance of the first conveying mechanism 312 in the horizontal direction, and reduce the requirements on the guide channel 22.

[0057] As shown in Figure 5, in some exemplary embodiments of this application, the second transport mechanism 321 is specifically a conveyor belt, and the conveyor belt is inclined, with the horizontal height of the end away from the entrance end of the guide channel 22 being higher than the horizontal height of the end closer to the entrance end of the guide channel 22. That is, the conveyor belt is inclined to facilitate the upward transport of floating objects.

[0058] Furthermore, in some exemplary embodiments of this application, baffles may be spaced on the conveyor belt, with the baffles perpendicular to the extension direction of the conveyor belt. This can prevent wet floating objects from sliding down the conveyor belt, while reducing the restriction on the tilt angle of the conveyor belt, reducing the horizontal occupancy distance of the second transport mechanism 321, and reducing the requirements on the guide channel 22.

[0059] As shown in 3 and 5, in some exemplary embodiments of this application, the horizontal width of the second transport mechanism 321 is approximately equal to the horizontal width of the guide channel 22. This arrangement allows the floating object to come into direct and complete contact with the second transport mechanism 321, thereby achieving separation of the floating object from the water.

[0060] In some exemplary embodiments of this application, the second transport mechanism 321 is provided with a gap in the horizontal direction, the width of which is approximately equal to the width of the floating object. This arrangement facilitates the flow of water out of the gap and serves as a filter.

[0061] Furthermore, multiple second transport mechanisms 321 are arranged along the extension direction of the guide channel 22, and the spacing between the second transport mechanisms 321 farther from the entrance end of the guide channel 22 is smaller than the spacing between the second transport mechanisms 321 closer to the entrance end of the guide channel 22. This arrangement is used to screen small floating objects one by one, facilitating further classification.

[0062] In some exemplary embodiments of this application, the horizontal position of the end of the second transport mechanism 321 near the top of the guide channel 22 is at least higher than the highest design water level of the guide channel 22.

[0063] like Figures 3 to 5 As shown, in some exemplary embodiments of this application, a barrier region 33 is provided between the first cleaning area 31 and the second cleaning area 32, and the barrier region 33 is used to intercept large floating objects.

[0064] The barrier zone 33 is designed to prevent large floating objects from directly crossing the first cleaning zone 31 into the second cleaning zone 32, which could damage the second transport mechanism 321 within the second cleaning zone 32. It also prevents the handling accuracy of floating objects from failing to meet the usage requirements.

[0065] It can be understood that, although the blocking area 33 is provided, water will flow from the gap to the second cleaning area 32, and in the process of large floating object treatment, the surface of the large floating object can be cleaned by the flow of water flow, so that small floating objects on the surface can be washed away.

[0066] The large floating object can be specifically a dead tree, a large branch, an animal carcass, household garbage, etc., and the small floating object can be specifically plastic, foam, wood chips, waterweed, water hyacinth, etc.

[0067] In some exemplary embodiments of the present application, the mechanical arm 311 is arranged such that when the surface of the large floating object has small floating objects, for example, waterweed is wrapped around the wood, the wrapped waterweed can be stripped by the mechanical arm 311 before the wood is transferred to the first transport mechanism 312.

[0068] As shown in Figures 3 to 5 In some exemplary embodiments of the present application, the blocking area 33 includes one or more intercepting nets 331 arranged along the extension direction of the guide channel 22. The intercepting net 331 can achieve the interception of the large floating object, and at the same time, the through hole thereof can pass the small floating object such as waterweed.

[0069] In some exemplary embodiments of the present application, a plurality of combined intercepting nets 331 are arranged on the same intercepting surface, and the spacing distance between the intercepting nets is greater than the set diameter of the large floating object. Such an arrangement can increase the probability of passing of the large floating object and reduce the possibility of blocking the intercepting position.

[0070] In some exemplary embodiments of the present application, the coverage height of the intercepting net 331 is greater than the highest design water level in the guide channel 22, and the shape of the intercepting net 331 is adapted to the shape of the water body along the vertical cross section of the extension direction of the guide channel 22 at the highest design water level.

[0071] In some exemplary embodiments of the present application, the blocking area 33 includes a plurality of intercepting nets 331 arranged along the extension direction of the guide channel 22, the spacing between adjacent intercepting nets 331 is not equal, and from the direction away from the entrance of the guide channel 22 to the direction close to the entrance of the guide channel 22, the spacing between adjacent intercepting nets 331 gradually increases, and a third transport mechanism is arranged between adjacent intercepting nets 331. Such an arrangement is used to intercept floating objects of different sizes, achieving further effects of cleaning and classification.

[0072] In some exemplary embodiments of the present application, from the direction away from the entrance of the guide channel 22 to the direction close to the entrance of the guide channel 22, the mesh diameter of the intercepting net 331 gradually increases.

[0073] As shown in Figure 1 and Figure 2As shown in some exemplary embodiments of the present application, the intercepting and guiding assembly 20 comprises a rotating mechanism 23 arranged perpendicularly to the horizontal plane, the rotating mechanism 23 is rotatably connected with the dam body 11, and one end of the intercepting mechanism 21 is connected with the rotating mechanism 23. Such arrangement is used to realize the rotation of the intercepting mechanism 21, so as to facilitate the guiding of the floating objects.

[0074] In actual application, the intercepting mechanism 21 is arranged at a certain angle with the water flow direction, so that the floating objects can move along the arrangement direction of the intercepting mechanism 21 after contacting the intercepting mechanism 21, thereby entering the guiding channel 22.

[0075] Different angle arrangements can be applied to different scenarios, for example, in the scenario of flood, the water flow speed is too fast, and the floating objects need to enter the guiding channel quickly, at this time, the angle between the intercepting mechanism 21 and the water flow direction is reduced, and the inclination degree is increased, so as to facilitate quick guiding. In a relatively calm state, the angle between the intercepting mechanism 21 and the water flow direction is increased, so as to facilitate the full interception of the floating objects and avoid missing.

[0076] As shown in some exemplary embodiments of the present application, Figure 1 and Figure 2 The rotating mechanism 23 and the dam body 11 are arranged with a first floating mechanism 24, so as to adjust the position cooperation between the rotating mechanism 23 and the water body. The arrangement of the first floating mechanism 24 makes the relative position between the rotating mechanism 23 and the water surface consistent, thereby facilitating the effective cleaning of the water layer where the floating objects are located.

[0077] As shown in some exemplary embodiments of the present application, Figure 1 and Figure 2 The intercepting mechanism 21 and the rotating mechanism 23 are arranged with a second floating mechanism 25, so as to adjust the position cooperation between the intercepting mechanism 21 and the water body. The arrangement principle of the second floating mechanism 25 is the same as that of the first floating mechanism 24, which will not be described here.

[0078] As shown in some exemplary embodiments of the present application, Figure 1 and Figure 2 The rotating mechanism 23 and the dam body 11 are arranged with a first floating mechanism 24, so as to adjust the position cooperation between the rotating mechanism 23 and the water body; and the intercepting mechanism 21 and the rotating mechanism 23 are arranged with a second floating mechanism 25, so as to adjust the position cooperation between the intercepting mechanism 21 and the water body.

[0079] As shown in some exemplary embodiments of the present application, Figure 1 and Figure 2 The intercepting mechanism 21 is a telescopic barrier net, which facilitates the adjustment of the angle between the intercepting mechanism 21 and the water flow direction, and avoids the occurrence of interception-free areas.

[0080] As shown in Figure 1 and Figure 2 In some exemplary embodiments of the present application, the intercepting mechanism 21 is a set of symmetrically arranged barrier nets, and two or more guiding channels 22 are located at the ends of the barrier nets away from each other. Such arrangement facilitates forming a complete guide on one side of the reservoir, disperses the processing of floating objects, and reduces the cleaning pressure of the sorting and cleaning assembly 30 in the guiding channel 22.

[0081] In the second aspect, referring to Figure 1 and Figure 2 In some exemplary embodiments of the present application, a hydroelectric power station is provided, which includes a dam body 11, a water inlet 12, and a dam floating object cleaning device as in any of the above embodiments, and the intercepting and guiding assembly 20 of the dam floating object cleaning device is located on the side of the dam body 11 close to the water inlet 12. The specific advantages of the dam floating object cleaning device can be found in any of the above embodiments or combinations of multiple embodiments, which will not be repeated here.

[0082] It should be understood that the present application does not limit its application to the detailed structure and arrangement of the components proposed in the present application. The present application can have other embodiments and can be implemented and executed in various ways. The foregoing variations and modifications fall within the scope of the present application. It should be understood that the present application extends to all alternative combinations of two or more individual features mentioned in the text and / or drawings. All these different combinations constitute alternative aspects of the present application. The embodiments described in the present application illustrate the best way known for implementing the present application and will enable those skilled in the art to utilize the present application.
