Description

Technical Field

[0001] This application relates to the field of photovoltaic cleaning technology, and further to a photovoltaic cleaning machine and its anti-detachment structure. Background Technology

[0002] In the field of photovoltaic power generation, in order to improve the power generation efficiency of photovoltaic modules, the upper surface of the photovoltaic modules needs to be cleaned regularly. In recent years, the industry has used cleaning robots to achieve automatic cleaning of photovoltaic modules.

[0003] In related technologies, to prevent cleaning robots from abnormally detaching from the surface of photovoltaic modules, commercially available photovoltaic cleaning robots typically have anti-detachment structures installed at both ends of the lower part of the body. For example, anti-detachment hooks are welded to the bottom of the body, and anti-detachment wheels are configured around these hooks. Alternatively, a large-diameter anti-detachment guard plate is coaxially installed at the lower end of any guide wheel. These structures, including the anti-detachment wheels and guard plates, support the edges of the photovoltaic modules from below, ensuring the cleaning robot's stable and safe movement relative to the modules. However, these technologies, whether using anti-detachment hooks or anti-detachment guard plates on the guide wheels, involve a large number of components. This not only increases the overall production and assembly difficulty but also tends to result in an excessively heavy cleaning robot, affecting its overall performance, and thus requires improvement. Utility Model Content

[0004] The purpose of this application is to provide a photovoltaic cleaning machine and its anti-detachment structure. By optimizing the layout of the anti-detachment structure, the number of its parts is reduced, thereby reducing the difficulty of its production and assembly, promoting the development of photovoltaic cleaning machines towards integration and lightweighting, improving overall performance, and helping enterprises reduce costs and increase efficiency.

[0005] The technical solution provided in this application is as follows:

[0006] On the one hand, this application provides an anti-detachment structure for a photovoltaic sweeper, comprising:

[0007] The bracket includes mutually perpendicular connecting rods and anti-detachment rods; the connecting rods are detachably connected to the body of the photovoltaic sweeper to keep the anti-detachment rods parallel to and spaced below the body of the photovoltaic sweeper;

[0008] The anti-detachment wheel is coaxially slidably sleeved on the outer periphery of the anti-detachment rod and detachably rotatably connected to the anti-detachment rod;

[0009] The system also includes a first guide wheel, which is coaxially slidably sleeved on the connecting rod and detachably rotatably connected to the connecting rod.

[0010] This application provides an anti-detachment structure for a photovoltaic cleaning machine. Through processes such as bending rods or welding, interconnected and perpendicular connecting rods and anti-detachment rods are formed. In actual production, the anti-detachment wheel is coaxially sleeved on the anti-detachment rod, allowing it to rotate and connect. The connecting rod is then connected to the lower side of the photovoltaic cleaning machine body, enabling the detachable installation of the anti-detachment wheel below the machine. This replaces the related technologies that require both anti-detachment wheels and anti-detachment guards. The corresponding bracket forming process is simple, and the anti-detachment structure only includes the bracket and the anti-detachment wheel. Furthermore, when the first guide wheel is coaxially sleeved on the connecting rod, the corresponding guide wheel can be simultaneously installed on the photovoltaic cleaning machine. The high integration of the guide wheel and the anti-detachment wheel reduces the number of components, making production and assembly convenient and efficient. Simultaneously, it facilitates the overall lightweight and miniaturized development of the photovoltaic cleaning machine, thereby improving its operational flexibility, reducing energy consumption, and effectively ensuring the comprehensive performance of the photovoltaic cleaning machine, thus helping enterprises reduce costs and increase efficiency.

[0011] In some embodiments, the end of the connecting rod away from the anti-detachment rod is provided with an external thread to be threaded and connected to the body.

[0012] This application provides an anti-detachment structure for a photovoltaic sweeper, which is provided with a connecting rod that is threadedly connected to the main body of the photovoltaic sweeper. This facilitates convenient and efficient assembly of the anti-detachment structure relative to the main body of the photovoltaic sweeper, while further simplifying the anti-detachment structure, reducing the number of its parts, and promoting its lightweight development.

[0013] In some embodiments, a first limiting hole is provided through the connecting rod radially and is located at the end of the connecting rod that extends into the body;

[0014] A locking element, adapted to the first limiting hole, is used to detachably connect the connecting rod and the body, restricting the connecting rod from rotating relative to the body about its own axis.

[0015] In some embodiments, a first limiting member is also included, which is fixedly disposed on the end of the anti-detachment rod away from the connecting rod by a fastener;

[0016] The radial dimension of the first limiting member is greater than the radial dimension of the anti-detachment rod and the inner diameter of the anti-detachment wheel. The end of the anti-detachment wheel away from the connecting rod rotates coaxially and abuts against the first limiting member.

[0017] In some embodiments, the end of the anti-detachment wheel away from the connecting rod is detachably covered with a flexible protective sleeve.

[0018] This application provides an anti-detachment structure for a photovoltaic cleaning machine, featuring a large-diameter first limiting component to ensure stable mounting of the anti-detachment wheel on the anti-detachment rod. The limiting structure is simple, easy to manufacture and deploy, and beneficial for energy conservation and cost reduction for enterprises. A flexible protective sleeve is used to cover the first limiting component, fasteners, and other structures, improving the appearance of the anti-detachment structure and the corresponding photovoltaic cleaning machine; it also helps prevent the tail end of the anti-detachment wheel from damaging the corresponding photovoltaic modules during deployment.

[0019] In some embodiments, the second limiting hole is radially through the connecting rod and located at the end of the connecting rod near the anti-detachment rod;

[0020] The second limiting member coaxially passes through the second limiting hole, and its two ends in the axial direction extend out of the corresponding end faces of the second limiting hole;

[0021] The end of the first guide wheel near the anti-detachment rod rotates to abut against the second limiting member.

[0022] This application provides an anti-detachment structure for a photovoltaic cleaning machine. Through the insertion and engagement of a second limiting member with the connecting rod, the displacement of the first guide wheel along the connecting rod axial direction is restricted, preventing the first guide wheel from sliding towards the anti-detachment rod and jamming relative to the bracket under force. This effectively ensures the functional stability of the first guide wheel. Simultaneously, the corresponding limiting structure is simple, easy to produce and assemble, and helps to further promote energy conservation and cost reduction for enterprises.

[0023] In some embodiments, a flexible isolation plate is coaxially sleeved on the outer periphery of the connecting rod and is located between the first guide wheel and the second limiting member, and between the first guide wheel and the body of the photovoltaic sweeper.

[0024] This application provides an anti-detachment structure for a photovoltaic cleaning machine. A flexible isolation plate is used to separate the first guide wheel from the second limiting member and the first guide wheel from the main body, so as to reduce the probability of the first guide wheel rotating and wearing relative to the second limiting member and / or relative to the main body of the photovoltaic cleaning machine. This helps to further ensure the stable rotation of the first guide wheel and extends the service life of the photovoltaic cleaning machine.

[0025] In some embodiments, the first guide wheel has a plurality of weight-reducing holes axially along its own length direction.

[0026] This application provides an anti-detachment structure for a photovoltaic cleaning machine, which has weight-reducing holes on the first guide wheel, helping to further promote the development of the anti-detachment structure and the corresponding photovoltaic cleaning machine towards lightweight design.

[0027] On the other hand, this application also provides a photovoltaic cleaning machine, including any of the above-described anti-detachment structures for photovoltaic cleaning machines, and further comprising:

[0028] The main body, the anti-detachment structure of the photovoltaic sweeper is detachably installed at one end of the lower side of the main body along the length direction of the photovoltaic sweeper via the connecting rod. At the other end of the lower side of the main body along the length direction of the photovoltaic sweeper, two second guide wheels are symmetrically arranged along the width direction of the photovoltaic sweeper. A second anti-detachment structure is also provided in the middle of the two second guide wheels.

[0029] In some embodiments, the second anti-detachment structure is the anti-detachment structure that does not include the first guide wheel. The second anti-detachment structure is coaxially arranged with the first guide wheel, the second guide wheel, and the anti-detachment wheel cooperate to achieve stable and safe movement of the photovoltaic cleaning machine on the surface of the photovoltaic module.

[0030] Compared with the prior art, the photovoltaic cleaning machine and its anti-detachment structure provided in this application have the following beneficial effects:

[0031] 1. This application uses interconnected and perpendicular connecting rods and anti-detachment rods to form a bracket structure for configuring anti-detachment wheels. In actual production, the anti-detachment wheel is coaxially rotated and sleeved on the anti-detachment rod, and the connecting rod is connected to the lower side of the photovoltaic sweeper body. This allows for the detachable installation of the anti-detachment wheel relative to the photovoltaic sweeper, replacing the solution of configuring anti-detachment wheels and anti-detachment guards in related technologies. The corresponding bracket molding process is diverse and simple to produce, and the anti-detachment wheel is easy to install and operate, effectively reducing the production and assembly difficulty of the anti-detachment structure for the photovoltaic sweeper and improving its deployment efficiency. Moreover, the overall structure of the anti-detachment structure for the photovoltaic sweeper is simple. Compared with the solutions in related technologies, it does not require many parts, effectively reducing the weight of the anti-detachment structure for the photovoltaic sweeper and the corresponding photovoltaic sweeper. This facilitates the flexible deployment of the photovoltaic sweeper at a lower cost and its adaptation to more complex environments, thereby improving the overall performance of the photovoltaic sweeper.

[0032] 2. The first guide wheel of this application is coaxially sleeved on the connecting rod. When installing the anti-detachment structure, the corresponding guide wheel can be installed on the photovoltaic sweeper body simultaneously. The guide wheel and the anti-detachment wheel are highly integrated, with fewer parts, making production and assembly convenient and efficient, which helps enterprises to further reduce costs and increase efficiency.

[0033] 3. In the technical solution of this application, only one first guide wheel is set, and several weight-reducing holes are opened on it along the length direction of the first guide wheel. This helps to further promote the overall development of the photovoltaic sweeper towards lightness and miniaturization, thereby significantly enhancing the advantages of the photovoltaic sweeper in terms of operational flexibility and low energy consumption, and effectively ensuring the comprehensive performance of the corresponding photovoltaic sweeper.

[0044] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0045] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0046] In the photovoltaic cleaning equipment industry, it is well known that the layout and design principles of the guide wheels and anti-detachment hooks on the lower drive head of the photovoltaic sweeper are intended to ensure the stable operation of the photovoltaic sweeper on the photovoltaic modules in windy environments and prevent accidental falls. Therefore, the anti-detachment problem of the photovoltaic sweeper is mainly solved by optimizing the mechanical layout of the guide wheels and anti-detachment hooks. In related technologies, the design principle of guide wheels is to reduce frictional resistance and movement obstruction between the guide wheels / anti-detachment devices and the photovoltaic module frame, while ensuring the guidance and anti-detachment of the photovoltaic cleaning machine. Therefore, manufacturers typically design four guide wheels evenly distributed, and all four guide wheels require power to rotate. The design goal of the anti-detachment hook is to ensure the reliability of the photovoltaic cleaning machine in extreme weather conditions (such as strong winds) and to enable it to frequently climb slopes on photovoltaic modules with large elevation changes without falling or getting stuck, thus maintaining the operational reliability of the photovoltaic cleaning machine. Currently, there are various forms of anti-detachment hooks on the market. Most involve welding the anti-detachment hook to the bottom of the main body and then using the anti-detachment hook to configure the anti-detachment wheel, or installing a large-diameter anti-detachment guard plate coaxially at the lower end of the guide wheel to form an anti-detachment wheel hook structure, thereby supporting the photovoltaic module from the lower edge. However, regardless of the solution, there are problems such as too many parts and excessive overall weight.

[0047] In one embodiment, reference is made to the accompanying drawings. Figures 1 to 6This invention provides an anti-detachment structure for a photovoltaic cleaning machine. By optimizing the arrangement of the guide wheel and anti-detachment hook, the number of overall parts of the photovoltaic cleaning machine is reduced, lowering its production and assembly difficulty. Simultaneously, it promotes the development of the machine towards integration and lightweight design, effectively improving overall performance and helping enterprises reduce costs and increase efficiency. It includes a bracket 1 and an anti-detachment wheel 2 mounted on the bracket 1. In this embodiment, preferably, a single rod is bent or welded to form a perpendicular connecting rod 11 and an anti-detachment rod 12, forming the aforementioned bracket 1 structure. During actual assembly, the anti-detachment wheel 2 is coaxially slidably sleeved on the outer periphery of the anti-detachment rod 12 and rotatably connected to it. Then, the connecting rod 11 is detachably connected to the body 100 of the photovoltaic cleaning machine, thus achieving that the anti-detachment rod 12 is parallel to the body 100 of the photovoltaic cleaning machine and is installed at intervals below it. The bracket 1 has a simple manufacturing process and the anti-detachment structure... The structure includes only the bracket 1 and the anti-detachment wheel 2; it also includes a first guide wheel 3, which is coaxially slidably sleeved on the middle of the connecting rod 11 and rotates relative to the connecting rod 11, so that the first guide wheel 3 can be detachably installed on the side below the body 100 of the photovoltaic sweeper; the high integration of the first guide wheel 3 and the anti-detachment wheel 2 further reduces the number of parts of the photovoltaic sweeper, which helps to make it efficient and convenient to produce, while promoting its development towards lightweight and miniaturization, which is conducive to ensuring the operational flexibility and endurance of the corresponding photovoltaic sweeper.

[0048] In one embodiment, based on the above embodiments, referring to Figures 1 to 6 Since photovoltaic modules are installed outdoors and need to withstand long-term wind and sun exposure, in order to make the anti-detachment structure suitable for the corresponding working environment and extend its service life, it is preferable to use a stainless steel rod forming bracket 1. That is, in this embodiment, the bracket 1 is a stainless steel bracket, which is easy to obtain, inexpensive, and has guaranteed rust resistance. Of course, in the embodiments of this application, other materials with high structural strength and strong corrosion resistance can also be selected to produce the bracket 1, but the forming material and production process of the bracket 1 should not be regarded as a specific limitation on the scope of protection of this application.

[0049] In one embodiment, the end of the connecting rod 11 furthest from the anti-detachment rod 12 is threaded externally, and the connecting rod 11 is threaded from bottom to top to fit the lower side of the body 100, thereby further reducing the number of parts and lowering the difficulty of manufacturing and assembling the anti-detachment structure. Furthermore, referring to... Figures 2 to 6 The connecting rod 11 has a first limiting hole 111 extending radially through its external thread. A locking member 112 is coaxially fitted inside the first limiting hole 111. After the end of the connecting rod 11 away from the anti-detachment rod 12 extends into the body 100 and is threadedly locked relative to the body 100, the locking member 112 sequentially passes through the through hole and the first limiting hole 111 on the body 100, thereby restricting the connecting rod 11 from rotating relative to the body 100 around its own axis. This improves the installation stability of the anti-detachment structure on the underside of the photovoltaic cleaning machine body 100. Figure 2 The locking component 112 can be configured as a locking bolt, pin, or other plug-in component. Since these are all existing technologies, they will not be described in detail here.

[0050] For anti-slip wheel 2, refer to... Figure 5 and Figure 6 The anti-detachment rod 12, at the end furthest from the connecting rod 11, is detachably and fixedly fitted with a first limiting member 4. In this embodiment, the first limiting member 4 may include a rigid washer 41, which is coaxially fixedly connected to the anti-detachment rod 12 via a fastener 42. The rigid washer 41 has a radial dimension larger than both the radial dimension of the anti-detachment rod 12 and the inner diameter of the anti-detachment wheel 2, allowing the end of the anti-detachment wheel 2 furthest from the connecting rod 11 to rotate coaxially and abut against the rigid washer 41, preventing the anti-detachment wheel 2 from detaching from the end of the bracket 1 furthest from the connecting rod 11. In this embodiment, the fastener 42 is preferably a bolt, screwed onto the end of the anti-detachment rod 12 furthest from the connecting rod 11 until its nut end abuts against the rigid washer 41 on the anti-detachment rod 12. Therefore, the first limiting member 4 is preferably a bolt plus a washer. Of course, the fastener 42 can also be other commonly used forms such as screws, which will not be elaborated upon here.

[0051] Furthermore, in this embodiment, preferably, the end of the anti-detachment wheel 2 away from the connecting rod 11 is detachably covered with a flexible protective sleeve 5, so as to cover the first limiting member 4 with the flexible protective sleeve 5, improve the appearance of the anti-detachment structure, and at the same time avoid the tail end of the anti-detachment wheel 2 from damaging the corresponding photovoltaic module, thereby improving the safety of the photovoltaic cleaning machine deployment operation; in order to facilitate the flexible protective sleeve 5 to slide along the axis of the anti-detachment wheel 2 and be fitted onto the anti-detachment wheel 2, it is preferable that the radial dimension of the rigid gasket 41 is smaller than the outer diameter of the anti-detachment wheel 2.

[0052] For the first guide wheel 3, refer to Figures 2 to 4 , Figure 6The end of the connecting rod 11 near the anti-detachment rod 12 is also detachably and fixedly equipped with a limiting structure. This limiting structure is used to prevent the first guide wheel 3 from sliding towards the anti-detachment rod 12 and getting stuck relative to the bracket 1 after being subjected to force. In this embodiment, the limiting structure preferably includes a second limiting hole 113 and a second limiting member 7. The connecting rod 11 passes through the second limiting hole 113 in its radial direction. The second limiting member 7 is coaxially adapted to pass through the second limiting hole 113 and keeps its two ends extending out of the corresponding end faces of the second limiting hole 113 in its axial direction, that is, protruding from the outer circle surface of the connecting rod 11. After the first guide wheel 3 is coaxially slid and sleeved on the outer circumference of the connecting rod 11 from the end of the connecting rod 11 with the external thread, its end near the anti-detachment rod 12 abuts against the part of the second limiting member 7 that extends out of the outer circle surface of the connecting rod 11. When the photovoltaic cleaning machine is running, it rotates relative to the part of the second limiting member 7 that extends out of the connecting rod 11, that is, the end of the first guide wheel 3 near the anti-detachment rod 12 rotates and abuts against the second limiting member 7. In this embodiment, the second limiting member 7 is preferably a pin, locking screw or other structure. Of course, other structures that achieve the same function are also possible and are not limited here.

[0053] In order to ensure the stable rotation of the guide wheel 3 and extend its service life, a flexible isolation plate 6 is coaxially sleeved on the outer periphery of the connecting rod 11 at the position between the first guide wheel 3 and the second limiting member; similarly, a flexible isolation plate 6 can also be correspondingly provided on the outer periphery of the connecting rod 11 between the first guide wheel 3 and the body 100 of the photovoltaic sweeper, so as to avoid friction between the first guide wheel 3 and the body 100 of the photovoltaic sweeper, thereby extending the service life of the corresponding photovoltaic sweeper body 100.

[0054] In addition, in this embodiment, to further promote the lightweight development of the anti-detachment structure, the first guide wheel 3 is preferably provided with weight-reducing holes 31 along its length direction, for example, referring to... Figure 6 Multiple weight-reducing holes 31 are provided and arranged in a circular array around the axis of the guide wheel 3; of course, the number of weight-reducing holes 31 can also be one, two, etc. Moreover, in this way, the first guide wheel 3 can be set as a conventional cylindrical structure, without the need for special structural design or a power source to drive it, so that it can rotate smoothly during operation. Compared with the existing technology, it is beneficial for enterprises to save energy and reduce costs.

[0055] The following describes the technical solution of this application in further detail, taking the application of the anti-detachment structure for a photovoltaic sweeper to a photovoltaic sweeper as an example. In one embodiment, a photovoltaic sweeper is provided, including a sweeper body 100 (the aforementioned body 100) and the anti-detachment structure for a photovoltaic sweeper described in any of the above embodiments. After the connecting rod 11 is threadedly locked to the body 100, the anti-detachment structure can be detachably installed on the underside of the body 100. Furthermore, to clearly illustrate the technical solution, this embodiment specifies that the two ends of the body 100 in the length direction are a first end 110 and a second end 120, respectively.

[0056] In one embodiment, refer to Figure 1 and Figure 5 The second end 120 is provided with the anti-detachment structure for the photovoltaic sweeper described in the above embodiment. The first end 110 is only provided with guide wheels 130 in a conventional form. Specifically, on the lower side of the first end 110 of the photovoltaic sweeper body 100, two second guide wheels 130 are installed parallel to each other along the width direction of the body 100. The two second guide wheels 130 are symmetrically arranged about the central axis of the body 100 along the length direction. At the same time, a second anti-detachment structure 200 is also installed at the first end 110. The second anti-detachment structure 200 is the above-mentioned anti-detachment structure excluding the first guide wheel 3. Furthermore, the second anti-detachment structure 200 is located at the first end 110 of the body 100 between adjacent second guide wheels 130, and the anti-detachment structure and the second anti-detachment structure 200 are arranged at intervals along the length direction of the photovoltaic sweeper body. (Refer to...) Figure 1 and Figure 5 The first end 110 of the photovoltaic cleaning machine is provided with two second guide wheels 130 in a conventional manner, while the second end 120 is not provided with second guide wheels 130. In this case, it is preferable to provide the second anti-detachment structure 200 and the anti-detachment structure including the guide wheel 3, i.e., the first anti-detachment structure, on the first end 110 and the second end 120 of the body 100, respectively, so that the second guide wheel 130 of the first end 110 and the first guide wheel 3 of the second end 120 cooperate to form a complete guide wheel and anti-detachment hook system to meet the application requirements of the corresponding photovoltaic module and realize the stable and safe movement of the photovoltaic cleaning machine on the surface of the photovoltaic module.

[0057] The implementation principle of this embodiment is as follows: In actual production, the anti-detachment wheel 2 is coaxially rotated and sleeved on the anti-detachment rod 12, and then the connecting rod 11 is connected to the lower side of the main body 100 of the photovoltaic sweeper, so that the anti-detachment wheel 2 can be detachably installed relative to the photovoltaic sweeper. The first guide wheel 3 is coaxially sleeved on the connecting rod 11, so that the corresponding first guide wheel 3 can be detachably installed relative to the photovoltaic sweeper simultaneously. Since the bracket 1 has a simple structure and molding process, the first guide wheel 3 and the anti-detachment wheel 2 are highly integrated, the number of corresponding anti-detachment structure parts is small, production and assembly are convenient and efficient, and it is conducive to promoting the lightweight and miniaturization of the corresponding anti-detachment structure, thereby effectively ensuring the comprehensive performance of the photovoltaic sweeper, such as its operational flexibility and battery life, and effectively promoting cost reduction and efficiency improvement for enterprises.

[0058] It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the protection scope of this application.
