Description

Technical Field

[0001] The present invention relates to the technical field of installation accessories for photovoltaic modules, and particularly to a profile installation assembly, a photovoltaic system and a method for installing a photovoltaic system. Background Art

[0002] A solar photovoltaic module fixes a lamination including solar cells through a frame of the photovoltaic module. The function of the module frame is to enhance the mechanical strength of the module, seal the edge of the lamination and fix the lamination on a bracket, thereby forming a solar photovoltaic module, simply referred to as a photovoltaic module or a module. Therefore, the strength of the module frame determines the overall strength of the photovoltaic module.

[0003] In related technologies, in order to improve the strength of profiles, profile pressing blocks for combining and fixing profiles are provided to achieve the installation and fixation of profiles. Specifically, fixing structures are provided on opposite sides of the profile pressing block to be engaged with C-shaped side grooves in two adjacent profiles, so as to fix the two adjacent profiles. During installation, first tilt the profile pressing member so that one side of one fixing structure is inserted into one side of the C-shaped side groove of one profile, and then rotate the profile pressing member so that the other side of the fixing structure is also inserted into the C-shaped side groove. After fixing the profile pressing member to the bracket through the mounting member, tilt another profile by a certain angle so that a part of the C-shaped side groove is engaged with the fixing structure on the profile pressing member, and then rotate the profile to completely engage the C-shaped side groove with the profile pressing member, thus achieving the fixation of the profile to the bracket.

[0004] However, for the above-mentioned profile pressing member, when installing a photovoltaic module, it is necessary to tilt the photovoltaic module. Usually, a photovoltaic module weighs dozens of kilograms.

[0063] Referring to Figures 1 to 13 , an embodiment of the present invention provides a profile mounting assembly for combining and fixing a profile 310. One side of the profile 310 is configured with a side groove 311. The profile mounting assembly includes a main pressing block 100 and a secondary pressing block 200. One side of the main pressing block 100 is provided with a first engaging portion 110 for engaging with the side groove 311 of a profile 310. The secondary pressing block 200 is fixedly connected to the side of the main pressing block 100 opposite to the first engaging portion 110. The secondary pressing block 200 is provided with a second engaging portion for engaging with the side groove 311 of another profile 310. Wherein, the second engaging portion is configured such that the dimension in the first direction gradually increases from the side away from the first engaging portion 110 towards the side close to the first engaging portion 110, and the first direction is the groove width direction of the side groove 311 when the first engaging portion 110 engages with the side groove 311.

[0064] A profile installation component provided by this technical solution realizes the connection between the profile 310 in a photovoltaic module 300 and the main pressing block 100 by providing a first engaging portion 110 on the main pressing block 100 and combining the first engaging portion 110 with the side groove 311 of the profile 310 in a photovoltaic module 300. The connection between another photovoltaic module 300 and the auxiliary pressing block 200 is realized by providing a second engaging portion on the auxiliary pressing block 200 and combining the second engaging portion with the side groove 311 of the profile 310 in another photovoltaic module 300. The auxiliary pressing block 200 is fixedly connected to the main pressing block 100 to realize the mutual connection between the two profiles 310. By connecting the profile installation component to the bracket, the connection between the profile 310 and the bracket is realized. Such a setting facilitates the combination of the profile installation component and the profile 310, and provides support for the profile 310 through the profile installation component. Among them, the main pressing block 100 is used to provide strength and support for the photovoltaic module 300, and the auxiliary pressing block 200 is used to provide the pulling force. The second engaging portion is configured in a form where the dimension in the first direction gradually increases from the side away from the first engaging portion 110 to the side close to the first engaging portion 110. When installing the profile 310 combined with the second engaging portion with the second engaging portion, it is not necessary to tilt the photovoltaic module 300. Only by aligning the side groove 311 on the profile 310 in the photovoltaic module 300 with the second engaging portion and pushing it flat in the direction of the main pressing block 100, the connection between the profile 310 and the auxiliary pressing block 200 can be realized. Such a setting makes the installation between the photovoltaic module 300 and the profile installation component more convenient and fast, and at the same time can reduce the installation difficulty and save effort.

[0065] It should be noted that, with reference to Figure 15 for understanding, the profile 310 is made of aluminum alloy material and is integrally formed by extrusion. The profile 310 includes a frame body and a support portion. The inside of the frame body is hollow to form a cavity. A side groove 311 is provided on one side of the frame body. A first flange 3111 and a second flange 3112 are connected to the groove side wall corresponding to the notch of the side groove 311. The first flange 3111 and the second flange 3112 are arranged in the side groove 311 and extend towards each other, so that the side groove 311 is configured as a C-shaped groove. The support portion is arranged on the top side of the frame body, and the support portion is used to support the workpiece to be installed. In the present invention, the workpiece to be installed is a photovoltaic module.

[0066] It is understandable that the main pressure block 100 and the auxiliary pressure block 200 can be an integrally formed structure, or they can be two independent structures fixed together to form a profile installation assembly. In this embodiment, the latter form is adopted, and a split structure is adopted, which is conducive to processing and forming, thereby reducing production costs; moreover, the main pressure block 100 and the auxiliary pressure block 200 can be made of different materials. For example, based on considerations of processing performance and comprehensive cost, the main pressure block 100 can be set as an extruded aluminum alloy part; and in order to ensure the structural strength of the auxiliary pressure block 200, while taking into account factors such as processing performance and comprehensive cost, the auxiliary pressure block 200 can be an extruded aluminum alloy part, a steel sheet metal part, etc. As a preferred solution, Figure 4 and Figure 5 As shown, the auxiliary pressing block 200 can be a sheet metal part formed by cold deformation of stainless steel or coated steel. Of course, in other embodiments, the surface of spring steel can also be provided with an anti-corrosion coating.

[0067] In one embodiment, if Figure 15 As shown, the two groove side walls corresponding to the groove opening of the side groove 311 of the profile 310 are respectively provided with a first flange 3111 and a second flange 3112. Figures 5 to 8 As shown, the auxiliary pressure block 200 includes an auxiliary pressure block body 220, and the second joint portion includes a first connecting member and a second connecting member respectively connected to the two ends of the auxiliary pressure block body 220 along the first direction, and the end of the first connecting member away from the auxiliary pressure block body 220 is configured with a first protrusion; the end of the second connecting member away from the auxiliary pressure block body 220 is configured with a second protrusion protruding in a direction away from the first connecting member; the first protrusion protrudes in a direction away from the second connecting member, and the first protrusion and the second protrusion respectively pass over the first flange 3111 and the second flange 3112 and are inserted into the side groove 311.

[0068] By arranging the first flange 3111 and the second flange 3112 on the two groove side walls corresponding to the groove opening of the side groove 311 of the profile 310, the first flange 3111 and the second flange 3112 are arranged relative to each other so that when the second combining part is combined with the side groove 311, the first flange 3111 and the second flange 3112 can block the second combining part, thereby improving the reliability of the combination of the second combining part and the side groove 311. The auxiliary pressure block body 220 is used to support the second combining part, and the first protrusion and the second protrusion are respectively arranged on the first connecting member and the second connecting member connected to the auxiliary pressure block body 220, so that the first protrusion and the second protrusion protrude in the direction away from each other, so that when the first protrusion and the second protrusion respectively pass over the first flange 3111 and the second flange 3112 and are inserted into the side groove 311, the first protrusion and the second protrusion can resist each other with the first flange 3111 and the second flange 3112, thereby limiting the second combining part from escaping from the side groove 311 of the profile 310, so as to ensure the reliability of the combination of the profile 310 and the second combining part.

[0069] Specifically, the auxiliary pressing block 200 can be set as follows: Figure 5 and Figure 6 As shown, the auxiliary pressing block body 220 is a plate-like structure. The opposite ends of the plate-like structure are bent and extended in the same direction respectively. The bent parts can be perpendicular to the plate body itself or in an obtuse angle form. The first protrusion and the second protrusion are respectively arranged at one end of the two bent parts far away from the body itself. Of course, the first protrusion and the second protrusion can be formed by making the end parts of the bent parts relatively thicker; or they can be formed by bending the free ends of the bent parts again. It can be understood that the first connecting part and the second connecting part are structures formed by the bent parts and the protruding parts. Through the above structural form, when connecting the side groove 311 of the profile 310 with the second joint part, during the process that the first protrusion and the second protrusion cross the first flange 3111 and the second flange 3112, the two bent parts can elastically deform in the direction of approaching each other, so that the first protrusion and the second protrusion can more easily cross the first flange 3111 and the second flange 3112, thus making it more labor-saving for the operator to install the profile 310.

[0070] As Figure 7 and Figure 8 shown, in one embodiment, the sides of the first protrusion and the second protrusion that are far away from each other are both inclined, and the distance between the two sides gradually increases from the side far away from the auxiliary pressing block body 220 to the side close to the auxiliary pressing block body 220. Through the above structure, the sides of the first protrusion and the second protrusion that are far away from each other form a guiding inclined plane, so that the guiding inclined plane can play a guiding role when the first protrusion and the second protrusion cross the first flange 3111 and the second flange 3112, so that the second protrusion part can be engaged with the side groove 311 of the profile 310 by pushing the profile 310 in the direction close to the auxiliary pressing block body 220, without tilting the profile 310 at a certain angle to snap the first protrusion into the side groove 311 and then rotating a certain angle to snap the second protrusion into the side groove 311. In this way, the labor during installation can be saved, and further the installation of the profile 310 is more convenient and fast.

[0071] In one embodiment, the sides of the first protrusion and the second protrusion facing the auxiliary pressing block body 220 are respectively attached to the first flange 3111 and the second flange 3112. The sides of the first protrusion and the second protrusion facing the auxiliary pressing block body 220 are attached to the first flange 3111 and the second flange 3112 on the profile 310, so as to make the mutual limitation between the first protrusion and the first flange 3111, and the second protrusion and the second flange 3112 more reliable.

[0072] As Figure 7 and Figure 8As shown, specifically, the side surfaces of the first protrusion and the second protrusion that are away from each other form an acute angle with the side surfaces of the first protrusion and the second protrusion that face the auxiliary pressure block body 220. Further, the side surfaces of the first protrusion and the second protrusion that face the auxiliary pressure block body 220 are parallel to the auxiliary pressure block body 220, and the first connecting member and the second connecting member are respectively perpendicular to the auxiliary pressure block body 220.

[0073] like Figure 3 , Figure 4 and Figure 13 As shown, in one embodiment, the main pressure block 100 includes a first side plate 120, a second side plate 130 and a third side plate 140, the second side plate 130 is connected to one side of the first side plate 120 along the first direction, and one end of the second side plate 130 away from the first combining portion 110 protrudes from the side surface of the first side plate 120; the third side plate 140 is connected to the other side of the second side plate 130 along the first direction, and one end of the third side plate 140 away from the first combining portion 110 protrudes from the side surface of the first side plate 120; when the second combining portion is clamped in the side groove 311, the opposite sides of the first flange 3111 and the second flange 3112 respectively abut against the second side plate 130 and the third side plate 140.

[0074] The first side plate 120 is used to connect and support the second side plate 130 and the third side plate 140, by setting the end of the second side plate 130 away from the first joint portion 110 to protrude from the side of the first side plate 120, and setting the end of the third side plate 140 away from the first joint portion 110 to protrude from the side of the first side plate 120, so that when the first protrusion and the second protrusion pass over the first flange 3111 and the second flange 3112 and enter the side groove 311, the side surfaces of the first flange 3111 and the second flange 3112 can abut against the second side plate 130 and the third side plate 140. So that the second side plate 130 and the third side plate 140 can limit the first flange 3111 and the second flange 3112, thereby limiting the relative movement of the profile 310 and the secondary pressing block 200 in the first direction. Since the first protrusion and the second protrusion respectively abut against the sides of the first flange 3111 and the second flange 3112, the first protrusion and the second protrusion can limit the movement of the profile 310 in a direction perpendicular to the first direction, and at the same time limit the rotation of the profile 310 relative to the auxiliary pressure block 200, so that the profile 310 and the auxiliary pressure block 200 are more stable and reliable after being combined with each other.

[0075] like Figure 1 , Figure 2 ,as well as Figures 9 to 11As shown, in one embodiment, the auxiliary pressing block 200 is fixedly connected to the first side plate 120. The auxiliary pressing block 200 is fixedly connected to the first side plate 120 to achieve the mutual connection between the auxiliary pressing block 200 and the main pressing block 100. Specifically, there is no limitation on the connection method between the auxiliary pressing block 200 and the first side plate 120.

[0076] As Figures 11 to 13 shown, in one embodiment, the first side plate 120 is provided with a clamping hole 121 penetrating in the thickness direction of the first side plate 120; the auxiliary pressing block 200 is provided with two oppositely arranged limiting members 230, the ends of the two limiting members 230 protrude in a direction away from each other, and the two limiting members 230 can be deformed in a direction approaching each other under an external force, and the two limiting members 230 can pass through the clamping hole 121 from one side of the first side plate 120 to the other side of the first side plate 120 and resist against the first side plate 120.

[0077] By providing the clamping hole 121 on the first side plate 120, by providing two oppositely arranged limiting members 230 on the auxiliary pressing block 200, and setting the ends of the two limiting members 230 to protrude in a direction away from each other, so that by passing the limiting members 230 through the clamping hole 121, the protruding part on the limiting members 230 can resist against the first side plate 120, thereby realizing the mutual limitation between the first side plate 120 and the limiting members 230, and further realizing the fixed connection between the auxiliary pressing block 200 and the first side plate 120. The above structure has the advantages of simple structure and convenient installation.

[0078] As Figures 11 to 13 shown, specifically, the two limiting members 230 are arranged on the side of the auxiliary pressing block body 220 facing away from the first connecting member and the second connecting member. The limiting member 230 is generally a plate-like structure, the two limiting members 230 are arranged oppositely and are generally parallel. One end of the limiting member 230 is connected to the side of the first side plate 120, and the end of the other end of the limiting member 230 protrudes in a direction away from the other limiting member 230 to resist against the first side plate 120. Further, the side of the protruding part of the limiting member 230 facing away from the auxiliary pressing block body 220 is configured as an inclined surface, and the inclined surface forms an acute angle with the limiting member 230 itself. That is, the distance between the two inclined surfaces of the two limiting members 230 gradually increases from the end away from the first side plate 120 to the end close to the first side plate 120. In this way, when connecting the auxiliary pressing block 200 to the first side plate 120, the inclined surface on the protrusion of the limiting member 230 can be used for guiding, and thus it is convenient to snap the limiting member 230 into the clamping hole 121.

[0079] As Figures 11 to 13As shown, in this embodiment, the shape of the card hole 121 is consistent with the connection line of the projections of the two limiting plates on the first side plate 120 after removing the protruding parts. For example, if the projections of the two parallel limiting plates on the first side plate 120 after removing the protruding parts are approximately rectangular, then the card hole 121 provided on the first side plate 120 is rectangular. It can be understood that the area of the card hole 121 should be appropriately slightly larger than the projection formed by the two limiting members 230 on the first side plate 120. Of course, the area of the card hole 121 should be smaller than the projection of the protruding part on the limiting member 230 on the first side plate 120. The distance between the side of the protruding part on the limiting member 230 opposite to the auxiliary pressing block body 220 and the auxiliary pressing block body 220 should be slightly greater than the thickness of the first side plate 120, so that the first side plate 120 can be clamped between the protruding part and the auxiliary pressing block body 220.

[0080] Figure 1 、 Figure 2 、 Figure 3 As shown, in one of the embodiments, an installation hole 122 penetrating along the thickness direction of the first side plate 120 is provided on the first side plate 120, and a through hole corresponding to the installation hole 122 is provided on the auxiliary pressing block 200. The installation member sequentially passes through the through hole and the installation hole 122 to connect the auxiliary pressing block 200 to the first side plate 120. By providing the installation hole 122 on the first side plate 120 and the through hole corresponding to the installation hole 122 on the auxiliary pressing block 200, it is realized that the auxiliary pressing block 200 and the first side plate 120 are fixedly connected by the installation member sequentially passing through the through hole on the auxiliary pressing block 200 and the installation hole 122 on the first side plate 120. Specifically, the installation member is a rivet, a through hole is provided on the auxiliary pressing block body 220 of the auxiliary pressing block 200, and the auxiliary pressing block body 220 and the first side plate 120 are fixedly connected by riveting. With such a setting, the structure is simple, the installation is convenient, and the reliability after connection is strong.

[0081] As Figure 3 and Figure 13 As shown, in one of the embodiments, a first avoidance notch 132 is provided on the second side plate 130, a second avoidance notch 141 is provided on the second side plate 130, and the first avoidance notch 132 and the second avoidance notch 141 correspond to each other; both ends of the second joint part pass through the first avoidance notch 132 and the second avoidance notch 141 respectively, and protrude from the sides of the second side plate 130 and the third side plate 140 that are away from each other. By providing the first avoidance notch 132 and the second avoidance notch 141 for avoiding the auxiliary pressing block body 220 on the second side plate 130 and the third side plate 140 respectively, the structural layout of the auxiliary pressing block 200 and the main pressing block 100 is made more reasonable.

[0082] As Figure 3 and Figure 13As shown, specifically, the first avoidance notch 132 and the second avoidance notch 141 are respectively provided at positions on the second side plate 130 and the second side plate 130 that are roughly corresponding to the mounting hole 122 or the clamping hole 121 on the first side plate 120. The first avoidance notch 132 and the second avoidance notch 141 are square notches, and the bottom surfaces corresponding to the first avoidance notch 132 and the second avoidance notch 141 are roughly flush with the side surface of the first side plate 120. In this way, when the secondary pressure block 200 is connected to the first side plate 120, the side surface of the secondary pressure block body 220 can be against the first side plate 120 and the bottom surface of the first avoidance notch 132 and the second avoidance notch 141, so as to increase the contact area between the secondary pressure block body 220 and the main pressure block 100, thereby improving the stability of the two after the connection.

[0083] It should be noted that, in the present invention, the number of the auxiliary pressure blocks 200 in a profile installation assembly is not limited, and can be one, two or more. Figure 9 and Figure 11 As shown, two spaced-apart secondary pressing blocks 200 are disposed on a main pressing block 100 to increase the contact area between the secondary pressing block 200 and the profile 310 , thereby improving the strength of the profile 310 and the profile mounting assembly after being connected.

[0084] like Figure 3 and Figure 13 As shown, in one embodiment, the main pressing block 100 further includes a fourth side plate 150 and a fifth side plate 160, one end of the fourth side plate 150 is connected to the side of the first side plate 120 away from the third side plate 140, and the fourth side plate 150 and the second side plate 130 are arranged opposite to each other in the first direction; the fifth side plate 160 is connected to the second side plate 130 and the fourth side plate 150 one end away from the first side plate 120, and the two ends of the fifth side plate 160 along the first direction protrude from the side of the second side plate 130 and the fourth side plate 150 away from each other, so as to engage with the side groove 311. The first side plate 120, the second side plate 130, the fourth side plate 150 and the fifth side plate 160 form a frame structure, and the two ends of the second side plate 130 along the first direction are arranged to protrude from the side of the second side plate 130 and the fourth side plate 150 away from each other, so that the protruding part of the fifth side plate 160 can engage with the side groove 311 on the profile 310. The second side plate 130 , the fourth side plate 150 and the fifth side plate 160 are connected to form the first connecting portion 110 mentioned above.

[0085] like Figure 3 and Figure 13As shown, in one embodiment, a first limiting groove 131 and a second limiting groove 151 are respectively provided on the sides of the second side plate 130 and the fourth side plate 150 that are away from each other. A first flange 3111 and a second flange 3112 are respectively disposed in the first limiting groove 131 and the second limiting groove 151. The side surfaces at both ends of the fifth side plate 160 are configured as the groove side walls of the first limiting groove 131 and the second limiting groove 151. By respectively providing the first limiting groove 131 and the second limiting groove 151 on the sides of the second side plate 130 and the fourth side plate 150 that are away from each other, it is convenient to accommodate the first flange 3111 and the second flange 3112 on the profile 310, and thus the limiting of the first flange 3111 and the second flange 3112 is realized.

[0086] As Figure 3 and Figure 13 shown, specifically, the side surfaces at both ends of the fifth side plate 160 facing the first side plate 120 are configured as the groove side walls of the first limiting groove 131 and the second limiting groove 151, so that when both ends of the fifth side plate 160 respectively cross the first flange 3111 and the second flange 3112 and enter the first limiting groove 131 and the second limiting groove 151, the side surface of the fifth side plate 160 can resist the first flange 3111 and the second flange 3112, and correspondingly, both ends of the fifth side plate 160 are respectively clamped in the side groove 311.

[0087] It is worth mentioning that, in this embodiment, as Figure 3 and Figure 13 shown, the first limiting groove 131 is formed by enclosing the end of the fifth side plate 160, the second side plate 130, and the rib 133 connected to the second side plate 130 and spaced from the fifth side plate 160. The second limiting groove 151 is set by recessing the end of the fourth side plate 150 towards the second side plate 130, and the recessed part and the end of the fifth side plate 160 enclose and define the second limiting groove 151.

[0088] In one embodiment, as Figure 3 and Figure 13 shown, a connection hole 134 is provided on the main pressing block 100, and a fastener passes through the connection hole 134 and is fixedly connected to the bracket. By providing the connection hole 134 on the main pressing block 100, the fixed connection of the main pressing block 100 to the bracket through the fastener is realized, thereby realizing the fixed connection of the profile 310 to the bracket. Specifically, the connection hole 134 is opened at the middle position of the second side plate 130 and the fourth side plate 150 on the main pressing block 100, and the connection holes 134 on the two side plates correspond to each other, so as to facilitate the fastener to pass through the connection hole 134 and be fixed to the bracket.

[0089] As Figures 14 to 16As shown in the figure, an embodiment of the present invention further provides a photovoltaic system, which includes a plurality of profiles 310 and brackets. Each profile 310 has a support portion 312 for carrying the workpiece to be installed. Each profile 310 has a side groove 311 on its side, and at least one profile mounting component is installed on the side groove 311. The profile mounting component is fixedly connected to the bracket.

[0090] By fixedly connecting the profile mounting component to the bracket, the profile 310 is installed and combined with the profile mounting component to achieve the fixed connection between the profile 310 and the bracket. The support portion 312 on the profile 310 is used to support and fix the photovoltaic module, thereby realizing the mutual connection between the photovoltaic module and the bracket. In this way, a photovoltaic system is formed. Specifically, two parallel purlins are provided on the bracket. The main pressing block 100 in the profile mounting component is fixedly connected to the purlin through fasteners, such as bolts. The profile 310 is the frame of the photovoltaic module, and profiles 310 are provided around the photovoltaic module. Generally, the profiles 310 corresponding to the long sides of the photovoltaic module are fixedly connected to the bracket through the profile mounting component. The profiles 310 of two adjacent photovoltaic modules are combined with the first engaging portion 110 on the main pressing block 100 and the second engaging portion on the auxiliary pressing block 200 respectively, so as to realize the installation of two adjacent photovoltaic modules on the bracket through the profile mounting component.

[0091] As Figure 17 shown, a method for installing a photovoltaic system includes the following steps: installing the first engaging portion 110 of the profile mounting component as described above in the side groove 311 of a profile; installing the profile mounting component on the bracket through fasteners; and clamping the side groove 311 of another profile with the second engaging portion of the profile mounting component.

[0092] Specifically, first install the first engaging portion 110 of a profile mounting component in the side groove 311 of a profile with a photovoltaic module. First, the protruding end of the fifth side plate 160 relative to the second side plate 130 in the main pressing block 100 of the profile mounting component is inserted into the side groove 311 of the profile, and then the profile mounting component is rotated by a certain angle so that the protruding end of the fifth side plate 160 relative to the fourth side plate 150 crosses the side groove 311 on the profile and is inserted into the side groove 311. In this way, the combination of the profile mounting component and the profile in one of the photovoltaic modules is realized.

[0093] Then, the profile mounting component is fixed to the bracket through fasteners. In this way, the fixed connection between the profile on one side of a photovoltaic module and the bracket is realized.

[0094] Then, align the profile in another photovoltaic module with the second fixing part in the secondary pressing block 200 of the profile mounting component that has been fixed to the bracket. By pushing the photovoltaic module in the direction close to the second fixing part, the opening of the side groove 311 in the profile of the photovoltaic module is engaged with the second fixing part under the guiding action of the inclined plane in the second fixing part. In this way, the fixed connection between another photovoltaic module and the bracket is achieved.

[0095] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0096] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent should be subject to the appended claims.
