Description

Technical Field

[0001] This utility model relates to the technical field of energy storage containers, and in particular to a sunshade canopy for an energy storage container and an energy storage container. Background Technology

[0002] Energy storage containers integrate energy storage systems within the container body for energy storage. Their structure mainly includes the container body, battery packs, and bidirectional energy storage converters. The battery packs are the energy storage units of the energy storage system, and commonly use high-performance batteries such as lithium-ion batteries and lithium iron phosphate batteries. The bidirectional energy storage converters are responsible for realizing the energy conversion between the battery packs and the power grid.

[0003] To increase the energy storage capacity per unit volume, as many battery packs as possible are usually installed in the container body. The heat generated by these densely packed battery packs during operation needs to be dissipated from the container body in a timely manner to avoid fire hazards caused by overheating of the battery packs. Therefore, existing energy storage containers usually have temperature regulation devices installed inside the container body to maintain a constant operating temperature inside the container body.

[0004] Since energy storage containers are generally placed outdoors in the open, this leads to:

[0005] During the high temperatures of summer, not only do the battery packs inside the container generate heat, but the container itself, exposed to sunlight, also gradually heats up as the exposure time increases. At this time, the heat dissipation pressure on the temperature regulation device will increase significantly.

[0006] In cold winter weather, such as in some areas of northern my country where the lowest temperature can reach -20℃ or even lower, the heat generated by the battery pack will be quickly dissipated into the surrounding environment. It is necessary to activate the temperature regulation device to raise the battery pack to the optimal operating temperature (for example, the optimal operating temperature range of lithium iron phosphate batteries is usually 15℃-35℃. When the temperature is below 15℃, the performance of lithium iron phosphate batteries will be affected. In a low temperature environment of around -10℃, the discharge capacity of the battery may drop to 60% to 70% of that at room temperature, the internal resistance increases, and the output power decreases). The lower the ambient temperature, the greater the pressure on the temperature regulation device to raise the temperature.

[0007] In addition, during rainy and snowy weather, rainwater and snow come into direct contact with the energy storage container. On the one hand, rainwater or melted snow may enter the interior of the energy storage container, which may negatively affect the normal operation of the internal structure of the energy storage container. On the other hand, in winter snowy weather, snow covers the top of the energy storage container, which is even more detrimental to the absorption of solar heat energy by the energy storage container after snowfall, resulting in a significant increase in the temperature rise pressure of the temperature regulation device before and after snowfall.

[0008] While installing a sunshade canopy on top of energy storage containers can prevent direct sunlight from hitting the container in summer and reduce the adverse effects of rain and snow on the normal operation of the container's internal structure, existing sunshade canopies on top of energy storage containers are mostly single-piece fabric structures, which have at least the following technical problems:

[0009] (1) When it is installed on the top of the energy storage container in a fixed installation manner, it cannot be retracted. In summer, when it is cloudy and windy, it is impossible to open the auxiliary heat dissipation to reduce the heat dissipation pressure of the temperature regulation device. In winter, when the temperature is low and the light conditions are good, it is also impossible to use sunlight to reduce the temperature rise pressure of the temperature regulation device.

[0010] (2) When the detachable installation method is used to install it on the top of the energy storage container, the operation of the whole canopy structure is cumbersome and complicated when it is retracted and opened, which is not conducive to the quick retraction and unfolding of the sun protection canopy in different seasons and different weather conditions in the same season. Utility Model Content

[0011] The purpose of this utility model is to provide a sunshade canopy for an energy storage container and an energy storage container, so that the sunshade canopy can be quickly opened or closed according to different seasons and different weather conditions in the same season, thereby reducing the operating pressure of the internal temperature regulation device of the energy storage container and thus reducing the operating energy consumption of the energy storage container.

[0012] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0013] In a first aspect, this utility model provides a sunshade canopy for an energy storage container, including a canopy mechanism, the canopy mechanism comprising:

[0022] In an optional embodiment, a groove is provided on the inner surface of the frame, and the push rod is slidably disposed inside the groove; and / or, the canopy mechanism further includes at least one reinforcing plate; the reinforcing plate extends along a first direction X perpendicular to the blade plate, and its two ends are respectively connected to the two opposite sides of the frame, and a groove is provided on the side surface of the reinforcing plate, and the push rod is slidably disposed inside the groove.

[0023] In this optional embodiment, "and / or" indicates that the structure before "and / or" and the structure after "and / or" are designed simultaneously or selectively. This optional embodiment includes at least the following specific design schemes:

[0024] (1) A linkage component is provided at one end of the blade plate in the first direction X, a groove is provided on the inner surface of the frame, the push rod is slidably located inside the groove, no reinforcing plate is provided, or a reinforcing plate is provided but no groove is provided on the reinforcing plate.

[0025] (2) A linkage component is provided at one end of the blade plate in the first direction X. No groove is provided on the inner surface of the frame, but a reinforcing plate is provided. A groove is provided on the side surface of the reinforcing plate, and the push rod is slidably located inside the groove.

[0026] (3) Both the frame has a sliding groove inside and a reinforcing plate with a sliding groove on the side surface. The blade plate has a linkage component at both ends in the first direction X. The push rod of each linkage component is slidably located inside the sliding groove on the corresponding side.

[0027] In an optional embodiment, a plurality of blade plates are arranged on both sides of the extension direction of each of the reinforcing plates.

[0028] In an optional embodiment, the blade plate has a first direction X, a second direction Y, and a third direction Z:

[0031] In an optional embodiment, the canopy mechanism further includes a temperature sensor, which is mounted on the frame and electrically or communicatively connected to the blade drive assembly. The blade drive assembly includes an information receiving and processing unit capable of receiving temperature information transmitted by the temperature sensor and opening or closing all the blades according to the temperature information.

[0032] Optionally, the canopy mechanism further includes at least one reinforcing plate, the two ends of which are respectively connected to the opposite sides of the frame, and the temperature sensor is fixed to the reinforcing plate.

[0033] In an optional embodiment, the sunshade canopy for the energy storage container further includes a snow removal mechanism installed on the frame for removing snow from the blades.

[0034] In an optional implementation, the snow removal mechanism includes:

[0035] A rotating shaft is rotatably mounted on the frame and arranged on the side of the blade plate closest to the ground;

[0036] A striking hammer is fixedly connected to the rotating shaft;

[0037] The hammer drive assembly is connected to the rotating shaft and can drive the rotating shaft to rotate, thereby causing the hammer to contact or move away from the blade plate.

[0046] The system can control the blade drive assembly and linkage assembly to quickly open or close all blades according to different seasons and weather conditions within the same season, thereby achieving the function of quickly opening or closing the roof mechanism. It is simple and convenient to operate, highly practical, and its applications include, but are not limited to:

[0047] On cloudy and windy summer days, all blades are opened to assist in heat dissipation and reduce the heat dissipation pressure on the temperature regulation device.

[0048] In winter, when the weather conditions are low and the sunlight is good, all the blades are opened to allow the energy storage container to be exposed to sunlight to absorb heat, thereby reducing the temperature rise pressure of the internal temperature regulation device of the energy storage container.

[0049] During hot summer weather, all blades are driven to close, providing sun protection for the energy storage container body and reducing the heat dissipation pressure on the temperature regulation device.

[0050] During rainy summer days, all blades are closed to prevent rainwater from flowing into the interior of the energy storage container.

[0051] When there is snow in winter, all blades are closed to prevent snowmelt from flowing into the interior of the energy storage container.

[0069] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the features of the following embodiments and their optional embodiments can be combined with each other.

[0070] First aspect

[0071] Reference Figure 1 This embodiment provides a sunshade canopy for an energy storage container, including a canopy mechanism 2. The canopy mechanism 2 includes a frame 22, a plurality of blade plates 24, and a blade plate drive assembly. Specifically, the frame 22 is suitable for being tilted and fixed to a part of the energy storage container body 1 away from the ground. The number of blade plates 24 is not specifically limited. These blade plates 24 are disposed inside the frame 22, and each blade plate 24 is rotatably connected to the frame 22. The blade plate drive assembly is installed on the frame 22 and is connected to each blade plate 24 through a linkage assembly. The blade plate drive assembly is configured to drive the linkage assembly to rotate each blade plate 24 relative to the frame 22, so as to open or close all the blade plates 24.

[0072] It should be noted that in this embodiment, the frame 22 can be an integral frame or a modular frame with multiple sets that can be reassembled for easy inspection and maintenance. The blade plate 24 can be selected according to different specifications and sizes depending on the actual situation.

[0073] The specific implementation scenario of this embodiment is as follows: the roof mechanism 2 is installed on the part of the energy storage container body 1 away from the ground. The installation method includes, but is not limited to, fixing it to the box wall of the energy storage container body 1 by mounting bracket 21, or integrating some other installation structures on the frame 22 and installing and fixing it to the box wall of the energy storage container body 1, or installing the frame 22 by other support pillars and placing the energy storage container body 1 in the space enclosed by the support pillars and the frame 22; the specific tilt angle of the frame 22 can be adjusted according to the actual situation.

[0074] The sunshade canopy for energy storage containers provided in this embodiment, by setting an automatically controllable opening and closing canopy mechanism for the energy storage container, can achieve at least the following beneficial effects:

[0075] The system can control the blade drive assembly and linkage assembly to quickly open or close all blades according to different seasons and weather conditions within the same season, thereby achieving the function of quickly opening or closing the roof mechanism. It is simple and convenient to operate, highly practical, and its applications include, but are not limited to:

[0076] Reference Figure 1 (1) When it is cloudy and windy in summer, start the blade plate drive assembly 25 to drive the linkage assembly to rotate each blade plate 24 relative to the frame 22 to open all the blade plates 24 to assist in heat dissipation, thereby reducing the heat dissipation pressure of the temperature regulation device and reducing the energy consumption of the energy storage container body 1.

[0077] (2) When the weather conditions are good in winter with low temperature and good sunlight, start the blade plate drive assembly 25 to drive the linkage assembly to rotate each blade plate 24 relative to the frame 22 to open all the blade plates 24, so that the energy storage container body 1 can be exposed to sunlight to absorb heat and heat up, thereby effectively reducing the heating pressure of the internal temperature regulation device of the energy storage container body 1 and reducing the energy consumption of the energy storage container body 1.

[0078] Reference Figure 2 (1) In the hot summer weather, the blade plate drive assembly is activated to drive the linkage assembly to rotate each blade plate 24 relative to the frame 22 to close all the blade plates 24, thereby avoiding direct sunlight on the energy storage container body 1, providing sun protection for the energy storage container body, thereby effectively reducing the heat dissipation pressure of the temperature regulation device in the energy storage container body 1 and reducing the energy consumption of the energy storage container body 1.

[0079] (2) In summer rainy weather, the blade plate drive assembly is activated to drive the linkage assembly to rotate each blade plate 24 relative to the frame 22 to close all blade plates 24 and prevent rainwater from flowing into the interior of the energy storage container.

[0080] (3) When there is snow in winter, the blade plate drive assembly is activated to drive the linkage assembly to rotate each blade plate 24 relative to the frame 22 to close all the blade plates 24 and prevent snow water from flowing into the interior of the energy storage container.

[0081] Reference Figure 3 In an optional embodiment of this invention, the blade plate drive assembly 25 and its linkage assembly can be disposed inside the frame 22; alternatively, at least one reinforcing plate 23 can be provided, and the blade plate drive assembly 25 and its linkage assembly can be disposed on one side of the reinforcing plate 23; or, at least one reinforcing plate 23 can be provided, and linkage assemblies can be provided on one side of each reinforcing plate 23 and on the inner side of the frame 22 opposite to it (the aforementioned reinforcing plate 23 side), and the blade plate drive assembly 25 can be disposed inside the frame 22 or on the aforementioned reinforcing plate 23 side.

[0082] When a linkage component is provided inside the frame 22, a groove 26 is provided on the inner surface of the frame 22, and the linkage component moves along the groove 26. The blade plate 24 has a first direction X, a second direction Y and a third direction Z. When a reinforcing plate 23 is provided and a linkage component is provided on one side of the reinforcing plate 23, the reinforcing plate 23 extends along the first direction X perpendicular to the blade plate 24 (that is, the reinforcing plate 23 extends along the second direction Y of the blade plate 24 when all blade plates 24 are closed), and the two ends of the reinforcing plate 23 are respectively connected to the opposite sides of the frame 22. A groove 26 is provided on the side surface of the reinforcing plate 23, and the linkage component moves along the groove 26.

[0083] This optional implementation includes at least the following specific design schemes:

[0084] (1) A linkage component is provided at one end of the blade plate 24 in the first direction X, and a groove 26 is provided on the inner surface of the frame 22. No reinforcing plate 23 is provided, or a reinforcing plate 23 is provided but the groove 26 is not provided on the reinforcing plate 23.

[0085] (2) A linkage component is provided at one end of the blade plate 24 in the first direction X. The inner surface of the frame 22 does not have a groove 26, but a reinforcing plate 23 is provided, and a groove 26 is provided on the side surface of the reinforcing plate 23.

[0086] (3) A sliding groove 26 is provided inside the frame 22, and a reinforcing plate 23 with a sliding groove 26 on the side surface is also provided. A linkage component is provided at both ends of the blade plate in the first direction X. Each linkage component moves along the sliding groove 26 on the corresponding side.

[0087] In an optional embodiment of this example, several blade plates 24 are arranged on both sides of the extension direction of each reinforcing plate 23. The several blade plates 24 located on each side of the reinforcing plate 23 are controlled to open or close synchronously by a set of blade plate driving components 25 and linkage components. Preferably, when two or more reinforcing plates 23 are provided, these reinforcing plates 23 are made parallel to each other, and the multiple sets of several blade plates 24 separated by each reinforcing plate 23 are distributed in a rectangular array.

[0088] Continue to refer to Figure 3In an optional embodiment of this example, the canopy mechanism 2 further includes a temperature sensor 4. The temperature sensor 4 is mounted on the frame 22 and electrically or communicatively connected to the blade drive assembly 25. The blade drive assembly 25 includes an information receiving and processing unit, capable of receiving temperature information transmitted by the temperature sensor 4 and opening or closing all blades 24 according to the temperature information. Thus, the temperature inside the energy storage container body 1 can be monitored through the temperature sensor 4, and a reasonable temperature threshold can be set. When the temperature is below the minimum threshold value, the blade drive assembly 25 automatically controls the closure of all blades 24; when the temperature is above the maximum threshold value, the blade drive assembly 25 automatically controls the opening of all blades 24. It should be noted that this optional embodiment also requires the cooperation of other control modules to avoid accidentally opening all blades 24 in rainy or snowy weather. Further optionally, the canopy mechanism 2 includes at least one reinforcing plate 23, with both ends of the reinforcing plate 23 connected to the opposite sides of the frame 22. The temperature sensor 4 is fixed to the reinforcing plate 23 to better sense the temperature inside the container.

[0089] Reference Figure 4 This provides a specific implementation method in which the blade plate drive assembly 25 drives the linkage assembly to control the opening or closing of all blade plates 24.

[0090] To better understand the structural details of this alternative implementation, refer to... Figure 5 It is Figure 4 The enlarged view of a partial structure in area A shows that the linkage assembly specifically includes a push frame 28, a push rod 27, and several linkage shafts 29. Specifically, each blade plate 24 is hinged with a push frame 28, which is connected to the rotating end of the blade plate 24 in the first direction X. The push rod 27 extends along the first direction X perpendicular to the blade plate 24 (i.e., the push rod 27 extends along the second direction Y of the blade plate 24 when all blade plates 24 are closed), and one end of the push rod 27 is fixedly connected to the output end of the blade plate drive assembly 25. Several linkage shafts 29 are spaced apart from the push rod 27 along its extension direction, and each linkage shaft 29 is slidably connected to each push frame 28. The blade plate drive assembly 25 can push and pull the push rod 27 to make each linkage shaft 29 slide along its corresponding push frame 28, thereby opening or closing all blade plates 24.

[0091] It should be noted that the blade plate drive assembly 25 may be an electric actuator, a cylinder piston rod assembly, or other structural components with similar functions known to those skilled in the art.

[0092] For the linkage assembly, the sliding connection method in which each linkage shaft 29 is slidably connected to each push frame 28 includes, but is not limited to: a limiting hole 281 is provided inside the push frame 28, so that each linkage shaft 29 passes through the corresponding limiting hole 281 and slides inside the limiting hole 281. The end of the linkage shaft 29 passing through the limiting hole 281 may be provided with an end cap or a protrusion on the side to prevent it from slipping out of the limiting hole 281; in addition, the limiting hole 281 may not be a hole structure but a long groove structure, and each linkage shaft 29 is slidably limited inside the long groove. The radial cross-section of the long groove may be provided with inwardly extending flanges at both ends. Correspondingly, the end of the linkage shaft 29 extending into the long groove may also be provided with an end cap or a protrusion on the side to cooperate with the flange of the long groove to prevent the linkage shaft 29 from slipping out of the long groove.

[0093] Reference Figure 5 In an optional embodiment of this invention, slots 241 are provided on two opposite side surfaces of the blade plate 24 along the second direction Y, extending through the blade plate 24 along the first direction X. These two slots 241 are offset along the third direction Z of the blade plate 24 and respectively extend through the two opposite side surfaces of the blade plate 24 along the third direction Z. When all blade plates 24 are in the closed state, the adjacent side surfaces of every two adjacent blade plates 24 along the second direction Y overlap each other through the slots 241. The slots 241 prevent interference when two adjacent blade plates 24 rotate, while also improving the sealing effect, thereby improving the rain and snow protection effect of the canopy mechanism.

[0094] To prevent snow from accumulating on the blade plate 24 and interfering with its normal opening and closing during snowy weather, in an optional embodiment of this invention, the sunshade canopy for the energy storage container also includes a snow removal mechanism; the snow removal mechanism is installed on the frame 22 and is used to remove snow from the blade plate 24.

[0095] The snow removal mechanism has a variety of optional structural types, including but not limited to using electric heating wires or hot water circulation pipes laid on the side of the canopy mechanism 2 facing the energy storage container, so that the snow melts by heating and flows down along the surface of the blade plate 24; or, installing a spraying mechanism on the side of the canopy mechanism 2 away from the ground, so as to automatically spray a thin layer of environmentally friendly antifreeze onto the surface of the blade plate 24 before or during snowfall, thereby reducing the adhesion between the snow and the surface of the blade plate 24, so that the snow can slide off more easily; or other forms of snow removal mechanism.

[0096] Reference Figure 6 3. Provides a specific snow removal mechanism.

[0097] To better understand the structural details of this alternative implementation, refer to... Figure 7 It is Figure 6The enlarged view of a portion of area B shows that the snow removal mechanism 3 specifically includes a rotating shaft 31, a hammer 32, and a hammer drive assembly. The rotating shaft 31 is rotatably mounted on the frame 22 and positioned on the side of the blade plate 24 closest to the ground. The hammer 32 is fixedly connected to the rotating shaft 31 via a connecting rod. The hammer drive assembly is drively connected to the rotating shaft 31. The hammer drive assembly can drive the rotating shaft 31 to rotate, thereby causing the hammer 32 to contact or move away from the blade plate 24. When the hammer drive assembly contacts the blade plate 24, it can cause the corresponding blade plate 24 to vibrate. Combined with the opening angle of the blade plate 24 and the tilt angle of the frame 22, the blade plate 24 can quickly slide off the lowest side of the frame 22, thus achieving the snow removal function.

[0098] It should be noted that the hammer 32 can be made of an elastic material such as rubber to avoid damaging the blade 24; and to further promote the rapid sliding of snow, the surface of each blade 24 can optionally be smoothed.

[0099] In this optional embodiment, the hammer drive assembly has a variety of optional structural forms, including but not limited to cylinder and connecting rod assembly or rotary motor and connecting rod assembly, etc., and is a two independent drive system from the blade plate drive assembly 25 of the canopy mechanism 2.

[0100] However, for ease of operation, the aforementioned hammer drive assembly may optionally include a spring seat 34, a locking block 35, and a torsion spring 33, and be linked with the push rod 27 of the canopy mechanism 2 in this embodiment to achieve snow removal while opening all blades 24. Specifically, the spring seat 34 is fixedly connected to the push rod 27 and arranged on the side of the blades 24 facing the ground, and the locking block 35 is elastically provided inside the spring seat 34. The torsion spring 33 is installed on the rotating shaft 31, one end of the torsion spring 33 is fixedly connected to the frame 22 as its fixed end 331, and the other end of the torsion spring 33 is its movable end 332. When the blade plate 24 is in the closed state, the movable end 332 of the torsion spring 33 abuts against the locking block 35 and the torsion spring 33 is in an elastic energy storage state. During the process of the blade plate 24 flipping from the closed state to the open state, the movable end 332 of the torsion spring 33 disengages from the locking block 35 and the torsion spring 33 releases elastic potential energy to drive the rotating shaft 31 to rotate and bring the hammer 32 to strike the corresponding blade plate 24. With the blade plate 24 itself having a certain degree of inclination, it can shake the snow off from the lowest end of the frame 22 when the blade plate 24 is covered with snow, and it will not fall on the top of the energy storage container body 1, thus ensuring the absorption effect of solar heat by the energy storage container body 1.

[0101] It should be noted that the specifications of the torsion spring 33 can be selected according to the actual situation.

[0102] Reference Figure 8Optionally, a limiting groove 351 is provided on the side of the locking block 35 near the blade plate 24. When the blade plate 24 is in the closed state, the movable end 332 of the torsion spring 33 is locked inside the limiting groove 351. The depth of the limiting groove 351 can be adjusted according to the actual situation, so that when the blade plate 24 is fully closed, the movable end of the torsion spring 33 is just locked inside the limiting groove 351. When the blade plate 24 is flipped open from the closed state, the movable end of the torsion spring 33 disengages from the limiting groove 351, and the elastic force stored in the torsion spring 33 causes the rotating shaft 31 to drive the striking hammer 32 to rotate and strike the corresponding blade plate 24.

[0103] Optionally, when the torsion spring 33 releases its elastic potential energy, i.e., when the blade plate 24 flips open from the closed state, the moving end 332 of the torsion spring 33 moves relative to the limiting groove 351 from the side closer to the rotating shaft 31 to the side farther away from the rotating shaft 31. The portion of the limiting groove 351 on the surface of the locking block 35, located on the side closer to the rotating shaft 31, is designated as the first side 3511, and the portion located on the side farther away from the rotating shaft 31 is designated as the second side 3512. Then, the distance H1 between the first side 3511 and the surface of the spring seat 34 on the side where the locking block 35 is mounted is greater than the distance H2 between the second side 3512 and the surface of the spring seat 34 on the side where the locking block 35 is mounted. This design allows the moving end of the torsion spring 33 to quickly disengage from the limiting groove 351 when the blade plate 24 is about to open, as the blade plate 24 rotates slightly upwards at a certain angle.

[0104] The design of the above-described structure in this optional embodiment can shake off snow when the roof mechanism 2 is covered with snow, at the initial stage of the transition from the closed state to the open state of the roof mechanism 2. This effectively prevents snow from falling on the top of the energy storage container body 1 and affecting the absorption effect of solar thermal energy by the energy storage container body 1. At the same time, it prevents snow water from entering the interior of the energy storage container body 1, further reducing the operating energy consumption of the energy storage container body 1 and ensuring the normal operation of the energy storage container body 1 in snowy weather.

[0105] To further improve the rapid response capability of the snow removal function, optionally, the top end face of the aforementioned locking block 35 is rounded at least at the corner of the second side 3512 of the limiting groove 351 to avoid interference with the torsion spring 33 entering and sliding out of the limiting groove 351.

[0106] Second aspect

[0107] This embodiment provides an energy storage container, which includes an energy storage container body 1 and a sunshade canopy for the energy storage container provided in any of the aforementioned embodiments. A frame 22 is inclinedly fixed to the portion of the energy storage container body 1 away from the ground. The fixing methods include, but are not limited to, fixing it to the wall of the energy storage container body 1 via a mounting bracket 21, or integrating other mounting structures onto the frame 22 and fixing it to the wall of the energy storage container body 1. The specific tilt angle of the frame 22 can be adjusted according to actual conditions.

[0108] In this embodiment, the projection of the frame 22 on the surface of the energy storage container body 1 away from the ground surrounds at least a portion of the surface of the energy storage container body 1. Preferably, but not limited to, the projection of the frame 22 on the surface of the energy storage container body 1 away from the ground surrounds the surface of the energy storage container body 1, so as to minimize direct sunlight on the energy storage container body 1 when the roof mechanism 2 is closed, and to minimize rain and snow falling on the surface of the energy storage container body 1 away from the ground.

[0109] In an optional embodiment of this example, the energy storage container body 1 has at least four corners, and each corner is fixed with a mounting frame 21. The frame 22 is fixedly installed on the mounting frame 21. The size of each mounting frame 21 can be designed as needed to adjust the tilt angle of the frame 22.
