Description

Technical Field

[0001] The invention belongs to the technical field of environmental data collection, and in particular relates to an environmental data collection device. Background Art

[0002] As an important facility for using solar energy to generate electricity, the scale and number of photovoltaic power stations are showing a rapid growth trend. While photovoltaic power generation provides green electricity to society, it also faces many challenges. Among them, the dust problem on the surface of photovoltaic panels has a significant impact on the power generation efficiency and operation stability of the power station.

[0003] Photovoltaic power stations are usually built in open areas, and their photovoltaic panels are exposed to the natural environment for a long time. Dust is very easy to settle and accumulate on the surface of the panels. The presence of dust will seriously interfere with the optical performance of photovoltaic panels. It will reflect, scatter and absorb solar radiation, thereby reducing the transmittance of solar radiation, resulting in a decrease in the effective light intensity received by the photovoltaic panels, and ultimately greatly reducing the output power. According to relevant research, even a thin layer of dust may reduce the power generation efficiency of photovoltaic panels by several percentage points. Over a long period of time, the loss of power generation will be considerable.

[0004] In order to maintain the efficient operation of photovoltaic power stations, smart grids will introduce dust monitoring devices to monitor dust data in the environment. However, in actual applications, existing dust monitoring devices will settle dust on the detection window of the sensor. Therefore, it is necessary to manually wipe it with a rag regularly. However, when wiping with a rag, the dust will cause the detection window to rub. As the number of uses increases, the detection window will gradually become blurred, affecting the transmission of light, and thus causing the accuracy of the sensor detection data to decrease. Inaccurate detection data will not be able to truly reflect the dust situation on the surface of the photovoltaic panel, making it difficult for power station operation and maintenance personnel to formulate reasonable cleaning plans and maintenance strategies, which seriously restricts the improvement of power generation efficiency and stable operation of photovoltaic power stations. Therefore, in response to the above problems, we propose an environmental data acquisition device. Summary of the invention

[0005] In order to overcome the problems existing in the related art, the present invention discloses an environmental data collection device.

[0008] The reel is slidably mounted in the housing and is located at one side of the sensor. The reel is used to reel in the transparent film to form a film roll. When the transparent film is unwound from the free end of the film roll and covers the sensor, a covering portion is formed. The covering portion is used to shield the detection window of the sensor from dust.

[0009] The cleaning mechanism includes a wiping cleaning member and an elastic member. The wiping cleaning member is arranged on the side of the winding shaft away from the sensor. The elastic member is used to push the winding shaft toward the side of the wiping cleaning member so that the film roll wound on the winding shaft abuts against the wiping cleaning member. When the film roll is unwound, the unwound part will be cleaned by friction of the wiping cleaning member.

[0010] Furthermore, it also includes a pressure member slidably connected to the top of the sensor for applying pressure to the covering portion, and the pressure member has a hollow portion at a position corresponding to the detection window;

[0011] The wiping cleaning member is slidably assembled in the shell and is transmission-connected to the pressure member.

The pressure member can slide downward until the covering portion is pressed.

[0012] Furthermore, a sliding rod is fixedly connected in the shell, a sliding seat is slidably mounted on the sliding rod, and the winding shaft is rotatably connected to the sliding seat.

[0013] Furthermore, the wiping cleaning member is slidably mounted on the sliding rod, and the pressure member is slidably mounted on the shell.

The two ends of the winding shaft are respectively rotatably connected with the two sliding seats, and the wiping cleaning piece is slidably assembled with the four sliding rods.

[0015] Furthermore, the elastic member is a coil spring which is sleeved on the outside of the slide rod and located between the slide seat and the sensor.

[0017] Furthermore, the first support member and the second support member are both provided in pairs and are both distributed on both sides of the winding shaft in the axial direction, and the two ends of the second sliding member are respectively fixedly connected to the two first support members.

[0018] Furthermore, a pressing member penetrating through the shell is fixedly connected to the side of the wiping cleaning member away from the winding shaft.

[0019] Furthermore, the wiping cleaning member includes a carrier and a flexible wiping member fixed to a side of the carrier close to the winding shaft.

[0020] The present invention discloses an environmental data collection device, which is designed to accurately collect dust data in the surrounding environment of a photovoltaic power station, and provide a key basis for the operation and maintenance of the power station. Its core components include a shell with a built-in sensor, a winding shaft, a transparent film, a cleaning mechanism, and a pressure piece. The sensor is used to detect dust, and the winding shaft is responsible for winding up the transparent film. During daily operation, the transparent film covering part can effectively prevent dust from directly settling on the sensor detection window to ensure accurate detection.

On the one hand, the flexible wiping part in its composite structure is used to cooperate with the friction with the film roll on the winding shaft to gently wipe off the dust and restore the light transmittance of the film; on the other hand, the pressure piece is linked to accurately adjust the pressure on the covering part, or to press to ensure dustproof, or to loosen to facilitate film replacement. The overall device effectively solves the problem of dust interference and helps photovoltaic power stations to operate efficiently and stably. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] Reference Figure 1-Figure 6 As shown, the environmental data acquisition device of the present invention is mainly composed of a housing 1 , a sensor 2 placed in the housing 1 for detecting dust, and further includes a winding shaft 42 and a cleaning mechanism 5 .

[0032] The reel 42 is slidably mounted in the housing 1 and is located on one side of the sensor 2. Its main function is to reel in the transparent film 3 to form a film roll 31. When the transparent film 3 is unwound from the free end of the film roll 31, the unwound portion will cover the sensor 2 to form a covering portion 32, which can block dust from the detection window 21 of the sensor 2 to prevent dust from directly settling on the detection window 21.

[0033] The cleaning mechanism 5 is composed of a wiping cleaning member 51 and an elastic member 52. The wiping cleaning member 51 is arranged on the side of the reel 42 away from the sensor 2, and the elastic member 52 is used to push the reel 42 toward the wiping cleaning member 51, so that the film roll 31 wound on the reel 42 is in close contact with the wiping cleaning member 51. When the film roll 31 is unwinding, the unwound part of the film will produce relative friction with the wiping cleaning member 51. In this process, the wiping cleaning member 51 can wipe off the dust on the surface of the film, ensuring that the cover 32 remains clean, and providing stable light transmission conditions for the sensor 2.

[0034] During normal use, the environmental data acquisition device is fixed on the side or near the photovoltaic panel, and the inclination angle of the environmental data acquisition device is kept consistent with the inclination angle of the photovoltaic panel. When performing the detection operation, the covering part 32 of the transparent film 3 is covered on the detection window 21 of the sensor 2, and the dust in the environment will naturally settle downward. The dust settled on the covering part 32 can be detected by the sensor 2, so that the dust data in the environment can be obtained so that the operation and maintenance personnel can understand the dust conditions around the photovoltaic power station in real time. Based on these accurate data, the operation and maintenance personnel can plan the cleaning cycle of the photovoltaic panel more scientifically to avoid waste of resources or loss of power generation efficiency caused by cleaning too early or too late. For example, if the data shows that the dust settling rate is relatively fast in the near future, the cleaning interval can be appropriately shortened; on the contrary, if the amount of dust is small and the growth is slow, the cleaning time can be appropriately extended to ensure that the cleaning work is both efficient and economical.

[0035] At the same time, as the detection operation continues, dust will gradually accumulate on the covering part 32 of the transparent film 3. When the dust accumulates to a certain extent and may affect the light transmittance and the detection accuracy of the sensor, the maintenance personnel can pull the free end of the film roll 31 outward to remove the covering part 32 with dust from the detection window 21, and then the part of the transparent film 3 unwound by the film roll 31 covers the detection window 21 to form a new covering part 32. Since the part of the film roll 31 located on the outside will abut and rub against the wiping cleaning member 51 during the unwinding process, the wiping cleaning member 51 can effectively wipe and remove the fine dust particles that may exist on the surface of the transparent film that has just been unwound from the film roll 31 and is about to become the new covering part 32, ensuring that the part of the transparent film newly covered on the detection window 21 is in a clean state.

[0036] It is worth mentioning that in this process, since the elastic member 52 always pushes the reel 42 toward the wiping cleaning member 51, a moderate and stable contact pressure is maintained between the film roll 31 and the wiping cleaning member 51, further improving the reliability of the cleaning effect; in addition, the existence of the contact force can prevent the film roll 31 from rotating at will, which plays a key role in maintaining the orderly unwinding of the transparent film 3. The stable unwinding process can prevent the transparent film 3 from wrinkling, jamming and other undesirable conditions, and avoid the light transmission affected by the uneven film surface, thereby ensuring that the sensor 2 continuously and stably receives light and accurately detects dust data. If the film roll 31 rotates at will, it may cause the transparent film 3 to be unevenly tight when unwinding, which is easy to damage the film body and reduce its service life, and ultimately affect the accuracy and stability of the entire device in monitoring environmental dust.

[0037] After the replacement of the new covering part 32 is completed, the entire device can quickly return to the state of accurately monitoring the environmental dust data, providing continuous and accurate information support for the operation and maintenance of the photovoltaic power station, helping the operation and maintenance personnel to timely and accurately grasp the dynamics of dust around the power station, so as to reasonably arrange the cleaning and maintenance of the photovoltaic panels and ensure the stability and improvement of the power generation efficiency of the power station.

[0038] In this embodiment, the environmental data acquisition device also includes a pressure piece 6 slidably connected to the top of the sensor 2 for applying pressure to the covering portion 32. The pressure piece 6 has a hollow portion 61 at the position corresponding to the detection window 21. This design cleverly takes into account the needs of applying pressure to the covering portion 32 and ensuring the normal lighting and detection functions of the sensor 2. It allows the covering portion 32 to fit closely to the detection window 21 to effectively block dust intrusion, and ensures that light can pass through the hollow portion 61 to reach the detection window 21 without hindrance, so that the sensor 2 can accurately capture dust information.

[0039] In this embodiment, the wiping cleaning member 51 is slidably assembled in the housing 1 and is transmission-connected with the pressure member 6. When the wiping cleaning member 51 slides toward / away from the winding shaft 42, it drives the pressure member 6 to slide upward / downward, and the pressure member 6 can slide downward until the covering portion 32 is pressed. Under normal conditions, the elastic member 52 pushes the winding shaft 42 toward the wiping cleaning member 51, so that the film roll 31 abuts against the wiping cleaning member 51, thereby pushing the wiping cleaning member 51 to move away from the winding shaft 42. In this process, the wiping cleaning member 51 drives the pressure member 6 to move downward until the pressure member 6 abuts against the covering portion 32 and is restricted from moving downward by the sensor 2. In this state, the covering portion 32 is clamped between the pressure member 6 and the sensor 2 under the pressure of the elastic member 52, so that dust can be prevented from invading from the edge gap between the covering portion 32 and the sensor 2, so as to prevent dust from eroding the detection window 21. When the transparent film covering part 32 needs to be replaced, the maintenance personnel can apply force to overcome the elastic force of the elastic member 52 to drive the wiping cleaning member 51 to slide toward the side close to the winding shaft 42. During this process, the wiping cleaning member 51 will drive the pressure member 6 to slide upward, releasing the pressing state of the old covering part 32, so that the maintenance personnel can remove the film section with more dust and cover the new covering part 32. After the new covering part 32 is in place, the maintenance personnel cancel the force applied to the wiping cleaning member 51. At this time, the elastic member 52 rebounds to drive the wiping cleaning member 51 to reset, and the pressure member 6 then presses the new covering part 32 downward to form a stable dustproof barrier.

[0040] In this embodiment, a slide bar 41 is fixed in the housing 1, a slide seat 43 is slidably mounted on the slide bar 41, and the reel 42 is rotatably connected to the slide seat 43. The slide bar 41 provides a stable sliding track for the slide seat 43, so that the slide seat 43 can smoothly reciprocate along the slide bar 41.

[0041] The reel 42 is rotatably connected to the slide 43, which gives the reel 42 a dual motion characteristic. On the one hand, the reel 42 can slide linearly along the slide 41 along with the slide 43. When it is necessary to remove the covering part 32 that is contaminated with a lot of dust, the slide 43 is pushed by external force to drive the reel 42 to move as a whole, leaving sufficient space for operation, so that maintenance personnel can efficiently complete the film segment replacement work. On the other hand, the rotation function of the reel 42 itself ensures that the transparent film 3 can be smoothly and continuously wound and unwound.

[0042] In this embodiment, the wiping cleaning member 51 is slidably assembled on the slide rod 41, and the pressure member 6 is longitudinally slidably assembled on the housing 1. Such an arrangement can stabilize the sliding tracks of the two.

[0043] In this embodiment, there are four slide bars 41, and the four slide bars 41 are grouped in pairs. There are two slide seats 43, and the two slide seats 43 are respectively slidably assembled with the two groups of slide bars 41. The two ends of the winding shaft 42 are respectively rotatably connected with the two slide seats 43. The wiping cleaning member 51 is slidably assembled with the four slide bars 41. Such an arrangement can improve the sliding stability of the wiping cleaning member 51 and the winding shaft 42.

[0044] In this embodiment, the elastic member 52 is a coil spring sleeved on the outside of the slide rod 41 and located between the slide seat 43 and the sensor 2. The elastic member 52 is arranged in this way to provide a stable elastic pushing force for the reel 42.

[0045] In this embodiment, the pressure member 6 has a first support member 62 on the lower side, and the wiping cleaning member 51 has a second support member 521 on the side close to the winding shaft 42. The second support member 521 has a guide slot 522. The guide slot 522 is inclined from top to bottom from the side close to the wiping cleaning member 51 to the side away from the wiping cleaning member 51. The first support member 62 is fixedly connected with a second sliding member 63 extending into the guide slot 522. This structural design establishes a precise and efficient transmission connection between the pressure member 6 and the wiping cleaning member 51. When the wiping cleaning member 51 slides along the slide rod 41, the inner wall of the guide slot 522 pushes the second sliding member 63 to move accordingly. Due to the special inclination angle of the guide slot 522, the second sliding member 63 can be converted into the up and down vertical movement of the pressure member 6 during the lateral displacement.

[0046] In this way, when the cover 32 of the transparent film needs to be replaced, the wiping cleaning member 51 slides toward the direction close to the winding shaft 42, driving the second sliding member 63 to move upward in the guide slot 522, and the pressure member 6 rises steadily, releasing the pressing state of the old cover 32, making the operation convenient; and after the new cover 32 is in place, the wiping cleaning member 51 slides in the opposite direction, prompting the pressure member 6 to press down, so that the new cover 32 is closely attached to the detection window 21, ensuring the dustproof effect. This linkage mechanism improves the convenience of operation and facilitates maintenance personnel to perform maintenance operations.

[0047] In this embodiment, there are two first support members 62 and two second support members 521, which are both distributed on both sides of the winding shaft 42, and the two ends of the second sliding member 63 are respectively fixed to the two first support members 62. The first support members 62 and the second support members 521 distributed on both sides make the pressure and transmission process more uniform.

[0048] In this embodiment, a pressing member 53 that penetrates the housing 1 is fixedly connected to the side of the wiping cleaning member 51 away from the winding shaft 42. This design greatly improves the convenience of operation of the device and provides a direct and efficient operation method for daily maintenance work of the operation and maintenance personnel. When the operation and maintenance personnel find that the covering part 32 of the transparent film 3 needs to be cleaned or replaced, or the pressure state of the pressure member 6 needs to be checked, there is no need to use complex tools. Just press the pressing member 53 outside the housing 1 to accurately drive the wiping cleaning member 51 to slide on the slide rod 41. This intuitive control method not only simplifies the operation process and reduces the requirements for the professional skills of the operation and maintenance personnel, but also can respond quickly in a short time.

[0049] In this embodiment, the wiping cleaning member 51 includes a carrier 511 and a flexible wiping member 512 fixed to the side of the carrier 511 near the winding shaft 42. The carrier 511, as the main structure of the wiping cleaning member 51, plays a key supporting and stabilizing role. It has sufficient rigidity to ensure that the overall structure does not deform and maintain a stable running trajectory during the frequent sliding of the wiping cleaning member 51 along the sliding rod 41, so that each cleaning action can accurately act on the film roll 31.

[0050] The flexible wiper 512 is a key part that directly contacts the film roll 31. Its material is soft, delicate and has strong adsorption properties. When the film roll 31 is unwound and moves relative to the flexible wiper 512, the flexible wiper 512 can gently fit the film surface and efficiently remove dust particles, which not only ensures the cleaning effect, but also avoids scratching the transparent film 3 due to excessive wiping force, thereby extending the service life of the transparent film 3.

[0051] In summary, the present invention discloses an environmental data collection device, which is designed to accurately collect dust data in the surrounding environment of a photovoltaic power station, and provide a key basis for the operation and maintenance of the power station. Its core components include a shell with a built-in sensor, a winding shaft, a transparent film, a cleaning mechanism, and a pressure piece. The sensor is used to detect dust, and the winding shaft is responsible for winding up the transparent film. During daily operation, the transparent film covering part can effectively prevent dust from directly settling on the sensor detection window to ensure accurate detection. When dust accumulation on the covering part affects the detection accuracy, the operation and maintenance personnel can drive the wiping cleaning part to slide by pressing the pressing part that runs through the shell. On the one hand, the flexible wiping part in its composite structure is used to cooperate with the friction with the film roll on the winding shaft to gently wipe off the dust and restore the light transmittance of the film; on the other hand, the pressure piece is linked to accurately adjust the pressure on the covering part, or to press to ensure dustproof, or to loosen to facilitate film replacement. The overall device effectively solves the problem of dust interference and helps photovoltaic power stations to operate efficiently and stably.
