Description

TECHNICAL FIELD

[0001] The utility model relates to a windproof structure field especially a mechanical windproof structure. BACKGROUND

[0002] For photovoltaic cleaning robots, windproof is a very important design consideration. When the cleaning robot stops at the parking space of the photovoltaic panel array to wait for the next cleaning, if it encounters a large wind force, it is easy to be blown away from the original position, which not only affects the continuity of the cleaning task, but also may cause the robot to be damaged. Therefore, designing a reliable windproof structure can effectively fix the cleaning robot and ensure its stable stay at the designated position, which is crucial for improving the performance and safety of the entire photovoltaic cleaning system.

[0003] The common windproof structure scheme on the market at present adopts electric push rod and other devices. This scheme fixes the cleaning robot on the parking space by driving the push rod to extend and retract through the motor. However, this solution has the problems of high cost and complex structure. For small and medium-sized photovoltaic power plants, the investment cost of such a windproof mechanism may become a bottleneck restricting its popularization and application. At the same time, the complex structure also increases the maintenance difficulty of the system, which is not conducive to ensuring long-term stable operation. Therefore, there is an urgent need for a simpler and more reliable windproof structure with lower cost to meet the needs of photovoltaic cleaning robots in actual application. SUMMARY

[0006] When the windproof device is in the first position, the fixed plate has a fixed interval with the upper surface of the slide rail to block the translation of the roller; when the windproof device is in the second position, the fixed plate is in contact with the upper surface of the slide rail.

[0007] Different from the prior art, the technical scheme realizes automatic switching of the windproof device between the first position and the second position through the weight distribution design of the connecting piece, when the windproof device is in the first position, a certain gap is kept between the fixed plate and the upper surface of the slide rail, thereby blocking the translation of the roller, when the cleaning robot is started, the roller is driven to roll by the power source, and the fixed plate is pressed down to be in contact with the surface of the slide rail, so that the windproof device is naturally switched to the second position, without the need of complex electric devices, the cleaning robot can be effectively fixed, the cleaning robot is prevented from being blown away in a strong wind environment, the cost is reduced, the maintenance efficiency is improved, and important guarantee is provided for stable operation of the photovoltaic cleaning system.

[0008] In some embodiments, the height of the fixed interval is less than or equal to the radius of the roller.

[0009] In some embodiments, the surface of the roller is provided with a plurality of annular arrays of grooves, and the circumferential direction of the roller is perpendicular to the extension direction of the grooves.

[0010] In some embodiments, the windproof device further comprises a limiting piece.

[0014] In some embodiments, the mechanical windproof structure further comprises a cleaning device, and the bottom of the cleaning device is provided with a plurality of rollers, and the rollers move along the slide rail.

[0015] Different from the prior art, the utility model provides a kind of mechanical windproof structure, with the following beneficial effects:

[0017] The windproof device utilizes the difference between the static and rotating states of the roller, and through the weight distribution of the connecting piece and the design of the surface groove, realizes the automatic switching of the windproof device between the first position and the second position, and increases the design of the limiting piece and the counterweight, further optimizes the overall stability and reliability. The limiting piece can prevent the fixed plate from rotating when the roller translates, ensuring that it always maintains the best windproof state; the counterweight ensures the stability of the windproof device in the first position through its own weight, and also plays a limiting role in the second position. These designs ensure that the windproof function can be reliably played in various working conditions.

For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0039] Please refer to Figures 1 to 5 The embodiment provides a mechanical windproof structure, which comprises a slide rail 10 and a windproof device 20, wherein the windproof device 20 comprises a connecting piece 21 and a fixed plate 22; the connecting piece 21 is rotatably arranged on one side of the slide rail 10, and the fixed plate 22 is arranged above the slide rail 10; the connecting piece 21 comprises a first end and a second end, the fixed plate 22 is connected with the first end, and the weight of the first end and the connecting piece 21 is less than the weight of the second end, so that the windproof device 20 is in a first position a; the connecting piece 21 is divided into the first end and the second end by a rotating connection; the first end is arranged above the second end.

[0040] When the windproof device 20 is located in the first position a, the fixed plate 22 has a fixed interval 23 with the upper surface of the slide rail 10, so as to block the translation of the roller 30; when the windproof device 20 is located in a second position b, the fixed plate 22 is in contact with the upper surface of the slide rail 10.

[0041] In the present application, when the roller 30 is in the braking state, the roller 30 will not rotate, at this time, if the roller 30 is subjected to an external force, the roller 30 will translate on the slide rail 10 under the action of the external force, and the fixed plate 22 will block the translation of the roller 30. That is to say, when the cleaning robot stops on the slide rail 10 and is subjected to strong wind, the roller 30 cannot rotate, but also cannot translate along the slide rail 10 due to the blocking effect of the fixed plate 22, so that the robot can stably stay at the specified position.

[0042] When the roller 30 is released from the brake, and the roller 30 rolls under the drive of the power source (i.e., the roller 30 brake device remains stationary, and the roller 30 rolling device moves), the outer surface of the roller 30 will drive the fixed plate 22 to rotate towards the direction of the slide rail 10; that is, using the principle similar to a seesaw, the roller 30 drives the fixed plate 22 to avoid downward during the rolling process. When the cleaning robot starts, the roller 30 begins to rotate and drives the fixed plate 22 to rotate downward during the rolling process, so that it is in contact with the surface of the slide rail 10. At this time, the limiting effect of the fixed plate 22 on the roller 30 will disappear, and the robot can freely move along the slide rail 10. Through the difference between the rotating and stationary states of the roller 30, intelligent switching of the windproof device 20 is realized.

[0043] The connecting piece 21 is divided into upper and lower parts by the rotating connection, the upper part is connected with the fixed plate 22, and the lower part is used for counterweight, so that the fixed plate 22 is always in a suspended state to avoid the translation of the roller 30. This not only enhances the stability of the device, but also ensures that the fixed plate 22 can always maintain a certain gap to effectively block the roller 30. It is worth noting that translation refers to the change of position of the roller 30 only, and no overturning occurs; rolling is the movement during which overturning occurs.

[0044] In this embodiment, through the weight distribution design of the connecting piece 21, the automatic switching of the windproof device 20 between the first position a and the second position b is realized. When the windproof device 20 is in the first position a, a certain gap will be maintained between the fixed plate 22 and the upper surface of the slide rail 10, thereby blocking the translation of the roller 30; when the cleaning robot starts, the roller 30 is driven to roll by the power source, and the fixed plate 22 is also pressed downward to be in contact with the surface of the slide rail 10, so that the windproof device 20 is naturally switched to the second position b. Without complex electric devices, the cleaning robot can be effectively fixed, avoiding being blown away in a strong wind environment, which not only reduces the cost, but also improves the maintenance efficiency, and provides an important guarantee for the stable operation of the photovoltaic cleaning system.

[0045] Please refer to Figure 3 In some embodiments, the height of the fixed gap 23 is less than or equal to the radius of the roller 30.

[0046] In the embodiment, the gap between the fixed plate 22 and the upper surface of the slide rail 10 is a fixed interval 23, and the height of the gap of the fixed interval 23 is less than or equal to the radius of the roller 30. This can not only effectively prevent the roller 30 from translating in the braking state, but also facilitate the roller 30 to smoothly press down the fixed plate 22 in the rolling state, thereby ensuring that the cleaning robot can normally perform the cleaning work. Specifically, when the cleaning robot is started, since the height of the fixed interval 23 between the fixed plate 22 and the slide rail 10 is less than or equal to the radius of the roller 30, the surface of the roller 30 can drive the fixed plate 22 to move downward until the fixed plate 22 is attached to the upper surface of the slide rail 10, and the roller 30 is not blocked, thereby ensuring that the roller 30 can smoothly pass above the fixed plate 22 to realize the movement of the cleaning robot.

[0047] Referring to Figure 3 and Figure 4 In some embodiments, the surface of the roller 30 is provided with a plurality of annular arrays of grooves 31, and the circumferential direction of the roller 30 is perpendicular to the extension direction of the grooves 31. The grooves 31 are strip-shaped grooves 31, and the circumferential direction of the roller 30 is perpendicular to the grooves 31 on the surface of the roller 30. When the roller 30 rolls, the grooves 31 on the roller 30 are engaged with the fixed plate 22 to drive the fixed plate 22 to rotate towards the slide rail 10.

[0048] In the embodiment, the surface of the roller 30 is provided with a plurality of annular arrays of grooves 31, and the grooves 31 are strip-shaped structures, and the extension direction of the grooves 31 is perpendicular to the circumferential direction of the roller 30, thereby enhancing the interaction between the roller 30 and the fixed plate 22 and further improving the reliability of the entire windproof structure. Specifically, when the cleaning robot is started and the roller 30 starts to rotate, the grooves 31 on the surface of the roller 30 will be engaged with the fixed plate 22, thereby driving the fixed plate 22 to rotate downward to contact the surface of the slide rail 10. In this way, the limitation of the fixed plate 22 to the roller 30 disappears, and the cleaning robot can freely move along the slide rail 10. This design utilizes the special structure of the surface of the roller 30, and through the interaction between the grooves 31 and the fixed plate 22, the automatic switching of the windproof device 20 is realized without any additional driving device. Meanwhile, the annular array layout of the grooves 31 can ensure that the surface of the roller 30 is always in effective contact with the fixed plate 22 at any rotation angle, thereby further improving the reliability and adaptability of the entire windproof structure.

[0049] Referring to Figures 3 to 5 In some embodiments, the windproof device 20 further comprises a limiting piece 24.

[0050] The limiting piece 24 is connected with the connecting piece 21, and the limiting piece 24 is located below the lower surface of the slide rail 10. When the windproof device 20 is placed in the first position a, the limiting piece 24 is in contact with the lower surface of the slide rail 10, so as to prevent the fixed plate 22 from rotating along the translation direction of the roller 30 when the roller 30 is translated. That is, the limiting piece 24 is used to limit the height of the fixed plate 22, and prevent the fixed plate 22 from rotating along the translation direction of the roller 30.

[0051] In the embodiment, when the cleaning robot is stopped on the slide rail 10, even if it is impacted by strong wind, causing the roller 30 to translate, the limiting piece 24 can effectively prevent the fixed plate 22 from rotating along the translation direction of the roller 30. Specifically, if the fixed plate 22 rotates, it cannot continue to block the translation of the roller 30. The limiting piece 24 limits the maximum height of the fixed interval 23 between the fixed plate 22 and the upper surface of the slide rail 10, so that the fixed plate 22 can only rise and fall within a limited range, ensuring that it always maintains a proper position, and further preventing the fixed plate 22 from being pushed too high by the roller 30 in the translated state in a strong wind environment, thereby ensuring that the gap between the fixed plate 22 and the upper surface of the slide rail 10 is always maintained, and further optimizing the stability and reliability of the entire windproof structure, so that it can continue to play a windproof role.

[0052] In some embodiments, the connecting piece 21 is rotatably connected with the side wall of the slide rail 10.

[0053] In the embodiment, the connecting piece 21 of the windproof device 20 and the side wall of the slide rail 10 are rotatably connected, so that the entire windproof device 20 can be more flexible in switching between the first position a and the second position b. Specifically, when the windproof device 20 is in the first position a, the fixed plate 22 maintains a gap with the slide rail 10, which can effectively block the translation of the roller 30. When the cleaning robot needs to move, it only needs to rotate the connecting piece 21 with the side wall of the slide rail 10, so as to rotate the entire windproof device 20 to the second position b, so that the fixed plate 22 is in contact with the surface of the slide rail 10. In this way, the restriction of the fixed plate 22 on the roller 30 disappears, and the cleaning robot can freely move along the slide rail 10.

[0054] This rotatable design not only improves the flexibility of the windproof device 20 in switching between the first position a and the second position b, but also ensures that the fixed plate 22 can maintain the best contact state with the slide rail 10 at any position, thereby ensuring the reliability of the windproof effect. At the same time, this flexibility also provides convenience for the daily maintenance and replacement of the cleaning robot, without the need for complex debugging and modification.

[0055] Please refer to Figure 4In some embodiments, the mechanical windproof structure further comprises: a counterweight 40; the counterweight 40 is arranged on the side of the connecting piece 21 away from the fixed plate 22, so that the windproof device 20 is in the first position a. In the second position b, the counterweight 40 is in contact with the lower surface of the slide rail 10 to limit the position.

[0056] In this embodiment, the design of the windproof device 20 is increased by the counterweight 40, which is arranged on the side of the connecting piece 21 away from the fixed plate 22. The main function of the counterweight 40 is to ensure the stability of the windproof device 20 in the first position a by its own weight. When the windproof device 20 is in the first position a, there is a gap between the fixed plate 22 and the upper surface of the slide rail 10, and the weight of the counterweight 40 exerts a certain pressure on the connecting piece 21, thereby ensuring that the fixed plate 22 can effectively block the translation of the roller 30. This design not only enhances the stability of the windproof device 20, but also ensures that the fixed plate 22 will not easily move or leave its working position under the action of strong wind or external force.

[0057] When the windproof device 20 switches to the second position b, the counterweight 40 will be in contact with the lower surface of the slide rail 10; at this time, the counterweight 40 plays a limiting role. Further, when the windproof device 20 switches to the second position b, the roller 30 moves out from the fixed plate 22, and under the action of the counterweight 40, the windproof device 20 will switch to the first position a.

[0058] Please refer to Figure 1 In some embodiments, the mechanical windproof structure further comprises: a cleaning device 50, the bottom of the cleaning device 50 is provided with a plurality of rollers 30, and the rollers 30 move along the slide rail 10.

[0059] In this embodiment, the mechanical windproof structure includes a cleaning device 50, which is equipped with a plurality of rollers 30 at the bottom, and these rollers 30 cooperate with the slide rail 10 to enable the cleaning device 50 to move smoothly along the slide rail 10. The cleaning device 50 is located above the photovoltaic panel, and its main function is to clean the dust and debris on the surface of the photovoltaic panel to ensure the efficient operation of the photovoltaic panel. When the cleaning device 50 is started, the rollers 30 at the bottom will roll on the slide rail 10, thereby realizing the movement function of the cleaning device 50. In this way, the cleaning device 50 can automatically move along the surface of the photovoltaic panel under the guidance of the slide rail 10, effectively covering every corner, ensuring the comprehensiveness and efficiency of cleaning. In addition, the design of the rollers 30 enables the cleaning device 50 to remain stable during movement, unaffected by external environmental factors such as wind or other interference, thereby improving the quality and efficiency of the cleaning work.

[0060] By adopting the above technical scheme, the utility model has the beneficial effects that compared with the prior art:

[0061] The utility model discloses a rotatable windproof device 20 is arranged on slide rail 10, including connecting piece 21 and fixed plate 22, when windproof device 20 is in first position a, fixed plate 22 and the surface between slide rail 10 keep certain gap, can effectively block the translation of gyro wheel 30 under external force, ensure that cleaning robot stable parking. This simple and reliable mechanical design does not need complex electronic control, and the system cost and maintenance difficulty are reduced greatly.

[0062] Windproof device 20 utilizes the difference of gyro wheel 30 static and rotation two states, through connecting piece 21 weight distribution and surface groove 31 design, realize the automatic switching of windproof device 20 between first position a and second position b, and increase the design such as stopper 24 and counterweight 40, further optimize the stability and reliability of whole. Stopper 24 can prevent fixed plate 22 from rotating when gyro wheel 30 translates, ensure that it always maintains the best windproof state, and counterweight 40 ensures the stability of windproof device 20 in first position a through its weight, and can also play the limiting effect when in second position b. These designs ensure that the windproof function can reliably play in various working conditions. The special design of gyro wheel 30 not only helps to enhance the friction between slide rail 10, but also can realize the automatic switching of windproof device 20 through the interaction with fixed plate 22, ensure the efficient play of cleaning function.

[0063] In summary, the mechanical windproof structure in the application provides a strong guarantee for the stable operation of the cleaning robot in a strong wind environment, improves the operation reliability, and also reduces the system cost and maintenance difficulty.
