[0003] In the related art, the detection of the connection position between the junction box and the wiring mainly relies on visual detection. However, the position detection accuracy fluctuates greatly, resulting in 3 cm - 5 cm long wiring remaining on the junction box after the wiring is cut, thereby reducing the recycling length of the wiring and causing waste. Summary of the Utility Model

[0004] In view of the above deficiencies in the related art, the present application provides a position detection device and a photovoltaic recycling device to solve the problem of small wiring recycling length caused by large fluctuations in position detection accuracy in the related art.

[0005] To solve the above technical problems, in a first aspect, the present application provides a position detection device, which includes:

[0006] A sensor, a plurality of the sensors are linearly arrayed along a first direction, and the distance between any two adjacent sensors is equally spaced and / or less than a preset distance. The sensor is used to detect whether there is a junction box or a wiring connected to the junction box on the photovoltaic panel; the first direction is parallel to the plate surface of the photovoltaic panel or forms an acute angle or an obtuse angle with the plate surface of the photovoltaic panel;

[0007] A controller, the controller is electrically connected to each sensor, and the controller is used to confirm the connection position between the wiring and the junction box according to the detection information detected by each sensor.

[0008] In a possible implementation manner of the first aspect, the sensor is used to detect whether there is the junction box or the wiring on the photovoltaic panel that moves along a second direction at a preset speed and passes through itself;

[0009] The second direction is parallel to the plate surface of the photovoltaic panel or forms an acute angle or an obtuse angle with the plate surface of the photovoltaic panel.

[0010] In a possible implementation manner of the first aspect, the controller is used to confirm the connection position between the wiring and the junction box according to the detection information of each sensor within a plurality of preset cycles.

[0011] In a possible implementation of the first aspect, both the first direction and the second direction are parallel to the plane of the photovoltaic panel, and the first direction is perpendicular to the second direction.

[0012] In a possible implementation of the first aspect, the distance between any two adjacent sensors is equal to 1 cm and / or the preset distance is 3 cm.

[0013] In a possible implementation of the first aspect, the position detection device further includes a position adjustment component, and the position adjustment component is used to drive a plurality of the sensors to move along the first direction.

[0014] In a possible implementation of the first aspect, the position adjustment component includes a driving member, a lead screw, and a fixed platform. The driving member is used to drive the lead screw to rotate around its central axis. The fixed platform is in threaded cooperation with the lead screw, and a plurality of the sensors are arranged on the fixed platform.

[0015] In a possible implementation of the first aspect, a plurality of the sensors are used to be arranged within 5 mm - 20 mm directly above the photovoltaic panel.

[0016] In a second aspect, the present application further provides a photovoltaic recycling device, and the photovoltaic recycling device includes:

[0017] The position detection device according to any one of the first aspect.

[0018] Compared with the related art, the present application has at least the following beneficial effects:

[0019] In the present application, since a plurality of sensors in the position detection device are linearly arranged in an array along the first direction, and the sensors are used to detect whether there is a junction box or a wiring connected to the junction box on the photovoltaic panel, and since the controller is electrically connected to each sensor, when using the position detection device to detect the junction box and the wiring on the photovoltaic panel, some sensors can detect the junction box, and some other sensors can detect the wiring, and the controller can receive the detection information detected by each sensor. When the controller determines that the detection information of a pair of adjacent sensors is different, that is, one of the adjacent two sensors detects the junction box and the other detects the wiring, thus the controller can determine that the connection position of the junction box and the wiring is between the adjacent two sensors, that is, the controller can confirm the connection position of the wiring and the junction box according to the detection information detected by each sensor.

[0020] Since the adjacent two sensors are arranged at equal intervals and / or the interval is less than a preset distance, on the one hand, by arranging the adjacent two sensors at equal intervals, the sensors can be evenly distributed in space. Furthermore, the sensors arranged at equal intervals can form a detection point array evenly distributed in the first direction, so that the detection density at each position on the photovoltaic panel is the same, and each position on the photovoltaic panel can be detected by the sensor with a relatively consistent probability. This is conducive to improving and stabilizing the detection accuracy, and further conducive to reducing the length of the remaining wiring, increasing the recovery length of the wiring, and reducing waste.

[0021] On the other hand, since the connection position between the junction box and the wiring is located between two adjacent sensors, the cutting position of the wiring is also located between two adjacent sensors. In this way, by setting the interval between any two adjacent sensors to be less than the preset distance and setting the preset distance to be less than or equal to 3 cm, even if there is still wiring remaining on the junction box after cutting, the length of the remaining wiring will be less than 3 cm. Compared with the related technology, this is conducive to reducing the length of the remaining wiring, increasing the recovery length of the wiring, and further reducing waste.

[0022] In summary, by arranging the adjacent two sensors at equal intervals and / or setting the interval to be less than the preset distance in this application, it is conducive to reducing the length of the remaining wiring, increasing the recovery length of the wiring, and further reducing waste.

[0039] As described in the background art of the present application, in order to recycle the wiring connected to the junction box on the photovoltaic panel, it is necessary to detect the connection position between the junction box and the wiring, so as to cut the wiring at the connection position and recycle the wiring.

[0040] In the related art, the detection of the connection position between the junction box and the wiring mainly relies on visual detection, but the position detection accuracy fluctuates greatly, resulting in 3 cm - 5 cm long wiring remaining on the junction box after the wiring is cut, and further resulting in a small recycling length of the wiring, causing waste.

[0041] Embodiment 1

[0042] In view of the above problems, the present application provides a position detection device to solve the problem of small wiring recycling length caused by large fluctuations in position detection accuracy in the related art.

[0043] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings:

[0044] As Figure 1 and Figure 2 shown, the position detection device 100 includes a sensor 1 and a controller (not shown in the figure). Among them, a plurality of sensors 1 are linearly arrayed along a first direction (such as the X direction in Figure 1 ), and the distance between any two adjacent sensors 1 is equally spaced and / or less than a preset distance. The sensor 1 is used to detect whether there is a junction box 21 or a wiring 22 connected to the junction box 21 on the photovoltaic panel 2; the first direction is parallel to the plate surface of the photovoltaic panel 2 or forms an acute or obtuse angle with the plate surface of the photovoltaic panel 2.

[0045] The controller is electrically connected to each sensor 1, and the controller is used to confirm the connection position between the wiring 22 and the junction box 21 according to the detection information detected by each sensor 1.

[0046] In this application, since a plurality of sensors 1 in the position detection device 100 are linearly arranged in a first direction, and the sensors 1 are used to detect whether there is a junction box 21 or a wire 22 connected to the junction box 21 on the photovoltaic panel 2, and since the controller is electrically connected to each sensor 1, when using the position detection device 100 to detect the junction box 21 and the wire 22 on the photovoltaic panel 2, some sensors 1 can detect the junction box 21, some other sensors 1 can detect the wire 22, and the controller can receive the detection information detected by each sensor 1. When the controller determines that the detection information of a pair of adjacent two sensors 1 is different, that is, one of the adjacent two sensors 1 detects the junction box 21 and the other detects the wire 22, based on this, the controller can determine that the connection position of the junction box 21 and the wire 22 is between the adjacent two sensors 1, that is, the controller can confirm the connection position of the wire 22 and the junction box 21 according to the detection information detected by each sensor 1.

[0047] Since any two adjacent sensors 1 are arranged at equal intervals and / or the interval is less than a preset distance, therefore, on the one hand, by arranging any two adjacent sensors 1 at equal intervals, the sensors 1 can be evenly distributed in space. Furthermore, the sensors 1 arranged at equal intervals can form a uniformly distributed detection point array in the first direction, so that the detection density at each position on the photovoltaic panel 2 is the same, and each position on the photovoltaic panel 2 can be detected by the sensor 1 with a relatively consistent probability. This is beneficial to improving and stabilizing the detection accuracy, and further beneficial to reducing the length of the remaining wire, increasing the recovery length of the wire, and reducing waste.

[0048] On the other hand, since the connection position of the junction box 21 and the wire 22 is between two adjacent sensors 1, the cutting position of the wire 22 is also between two adjacent sensors 1. Thus, by setting the interval between any two adjacent sensors 1 to be less than the preset distance and setting the preset distance to be less than or equal to 3 cm, even if there is still a wire 22 remaining on the junction box 21 after cutting, the length of the remaining wire will be less than 3 cm. Compared with the related technology, this is beneficial to reducing the length of the remaining wire, increasing the recovery length of the wire 22, and further reducing waste.

[0049] In summary, in this application, by arranging any two adjacent sensors 1 at equal intervals and / or setting the interval to be less than the preset distance, it is beneficial to reduce the length of the remaining wire, increase the recovery length of the wire, and further reduce waste.

[0050] Furthermore, any two adjacent sensors 1 are arranged at equal intervals and the interval is less than the preset distance.

[0051] A layout of sensors 1 with equal and small spacing can provide a more intensive detection coverage for the photovoltaic panel 2. This means that even very small changes in the connection positions of the junction box 21 and the wiring 22 can be captured, greatly reducing the detection blind spots, thereby facilitating the improvement of the accuracy and precision of the detection of the connection positions.

[0052] Further, the spacing between any two adjacent sensors 1 is equal to 1 cm and / or the above preset distance is 3 cm.

[0053] With such a setting, on the one hand, a spacing of 1 cm divides the photovoltaic panel 2 into very small detection areas, which can more precisely detect the positions of the junction box 21 or the wiring 22, facilitating the further improvement of the detection precision.

[0054] On the other hand, to a certain extent, since the cutting position of the wiring 22 is between two adjacent sensors 1, a spacing of 1 cm can make the length of the wiring remaining on the junction box 21 less than or equal to 1 cm, which is conducive to further increasing the recovery length of the wiring 22 and thus further reducing waste.

[0055] In addition, setting the above preset distance to 3 cm can not only make the length of the wiring remaining on the junction box 21 less than 3 cm, facilitating the increase of the recovery length of the wiring 22 and reducing waste, but also a relatively large preset distance is conducive to the arrangement between adjacent sensors 1 to a certain extent.

[0056] Further, in a preferred embodiment, the spacing between any two adjacent sensors 1 is equal to 1 cm and the above preset distance is 3 cm.

[0057] With such a setting, it is not only conducive to further improving the detection precision and further reducing waste, but also can relatively increase the selectable range of the spacing between sensors 1, facilitating the arrangement between adjacent sensors 1.

[0058] In other embodiments, according to different actual required detection precisions, the spacing b can also be any other value other than 1 cm, such as 1.2 cm, 1.4 cm, or 1.6 cm, etc. The setting of the spacing b is relatively flexible.

[0059] In other embodiments, the above preset distance can also be 2.9 cm, 2.8 cm, or 2.7 cm, etc. The setting of the above preset distance is relatively flexible.

[0060] Regarding the number of sensors 1, in the embodiments of the present application, according to different actual detection ranges and different spacings between two adjacent sensors 1, the number of sensors 1 can be any value such as 40, 50, or 60, etc. The setting of the number of sensors 1 is relatively flexible, and the embodiments of the present application do not make specific limitations in this regard.

[0061] For sensor 1, in the embodiments of the present application, sensor 1 is a photoelectric sensor.

[0062] With such a setting, on the one hand, since the photoelectric sensor has the characteristics of high sensitivity and high precision, therefore, setting sensor 1 as a photoelectric sensor is beneficial to accurately detect the junction box 21 and the wiring 22, and further beneficial to more accurately confirm the connection position of the junction box 21 and the wiring 22.

[0063] On the other hand, since the visual detection device in the related art requires professional maintenance technicians, the labor cost is high. In the present application, setting sensor 1 as a photoelectric sensor does not require professional maintenance technicians for repair, and primary maintenance personnel can perform maintenance, which is beneficial to reducing the maintenance cost.

[0064] On the third hand, in the related art, in order to provide a good detection environment for visual detection, it is necessary to clean the photovoltaic panel 2, which increases the cost. The photoelectric sensor can filter out the dirty objects on the photovoltaic panel 2 by setting the light value of the detected object and combining with a unique detection algorithm, and thus there is no need for cleaning, which is beneficial to reducing the cost.

[0065] Regarding the position of the junction box 21 on the photovoltaic panel 2, Figure 2 There are three different models of photovoltaic panels in [reference], namely the first photovoltaic panel 23, the second photovoltaic panel 24, and the third photovoltaic panel 25. For different models of photovoltaic panels, the position of the junction box 21 on the photovoltaic panel is also different. As Figure 2 shown, the positions of the junction box 21 on the first photovoltaic panel 23, the second photovoltaic panel 24, and the third photovoltaic panel 25 are all different.

[0066] Among them, the junction box 21 on the second photovoltaic panel 24 is smaller, the wiring 22 is shorter, and it has no recycling value. Therefore, only the junction box 21 needs to be removed. In this case, only the position of the junction box 21 on the second photovoltaic panel 24 needs to be detected, and no specific requirements are made for the detection accuracy.

[0067] The junction boxes 21 on the first photovoltaic panel 23 and the third photovoltaic panel 25 are larger, the wiring 22 is longer, and they have recycling value. Therefore, it is necessary to accurately detect the positions of the junction box 21 and the wiring 22 to accurately recognize the connection position of the junction box 21 and the wiring 22. Therefore, high requirements are imposed on the detection accuracy.

[0068] Further, sensor 1 is used to detect whether there is a junction box 21 or a wiring 22 on the photovoltaic panel 2 that moves along the second direction (such as the Y direction in Figure 2 [reference]) at a preset speed and passes through itself. Among them, the second direction is parallel to the plate surface of the photovoltaic panel 2 or forms an acute angle or an obtuse angle with the plate surface of the photovoltaic panel 2.

[0069] The sensor 1 is used to detect whether there is a junction box 21 or a wiring 22 on the moving photovoltaic panel 2. Compared with detecting whether there is a junction box 21 or a wiring 22 on the stationary photovoltaic panel 2, each sensor 1 does not need a large detection range, that is, each sensor 1 can have a relatively small detection range. The reduction of the detection range can improve the position detection accuracy of the sensor 1, which is beneficial to improving the confirmation accuracy of the connection position between the junction box 21 and the wiring 22, and is beneficial to reducing the residual length of the wiring 22 on the junction box 21.

[0070] Further, the controller is configured to confirm the connection position between the wiring 22 and the junction box 21 according to the detection information of each sensor 1 within a plurality of preset cycles.

[0071] With such a setting, through the detection information within a plurality of preset cycles, the controller can obtain more comprehensive and richer data, which helps to reduce the errors and uncertainties that may occur in a single detection information, thereby helping to more accurately confirm the connection position between the wiring 22 and the junction box 21.

[0072] Regarding the detection information within a plurality of preset cycles, it should be noted that there are two types of detection information within a plurality of preset cycles. The first type is the detection information obtained by the sensor 1 during detection within a plurality of preset cycles, and the second type is the detection information obtained by the controller receiving the detection information of the sensor 1 within a plurality of preset cycles. The embodiments of the present application do not make specific limitations on this. In this embodiment, the second type is taken as an example for illustration.

[0073] For the detection of the connection position between the wiring 22 and the junction box 21, in a preferred embodiment, the photovoltaic panel 2 passes through the sensor 1 at a certain speed ν, and the moving direction is as Figure 2 shown by the Y direction in the figure. The controller receives the value α of the sensor 1 at a plurality of fixed preset cycles T. When the sensor 1 detects the junction box 21 or the wiring 22, α is a valid value of 1, and when the sensor 1 does not detect the junction box 21 or the wiring 22, α is an invalid value of 0.

[0074] Therefore, the distance collected in each preset cycle T: S = νT·α;

[0075] The effective length value of the entire detection process: L = S0 + S1 + S2 + …….

[0076] As shown in Figure 3As shown in the figure, each column of small squares corresponds to a sensor 1, and each small square represents a detection point of the sensor 1, that is, each small square represents a distance S collected in a preset period T. Among them, the small squares filled with black shadows represent the distance S when α is the effective value 1, and the small squares without black shadow filling represent the distance S when α is the invalid value 0. Therefore, all the small squares filled with black shadows in each column of small squares represent an effective length value L. Also, since each sensor 1 is arranged above the photovoltaic panel 2, to a certain extent, the effective length value L represents the dimension of the junction box 21 or the wiring 22 in the second direction in the top view of the photovoltaic panel 2. Thus, by combining all the effective length values L, the object characteristic positions of the junction box 21 and the wiring 22 can be obtained.

[0077] From the above description, it can be seen that after the detection is completed, by calculating and comparing two adjacent effective length values L, the connection position between the junction box 21 and the wiring 22 can be found. Then, based on the actual positions of the sensors 1 corresponding to the two adjacent effective length values L, the actual position of the connection position between the junction box 21 and the wiring 22 can be obtained, which is beneficial to more accurately obtain the actual connection position between the wiring 22 and the junction box 21.

[0078] For the first direction and the second direction, further, in a preferred embodiment, both the first direction and the second direction are parallel to the panel surface of the photovoltaic panel 2, and the first direction is perpendicular to the second direction.

[0079] In the first aspect, setting the first direction parallel to the panel surface of the photovoltaic panel 2 can make the distance between each sensor 1 and the panel surface of the photovoltaic panel 2 the same, which is beneficial to making each sensor 1 receive the same signal intensity, and further beneficial to ensuring the consistency of the detection accuracy of each sensor 1 and reducing the detection error.

[0080] In the second aspect, both the first direction and the second direction are set parallel to the panel surface of the photovoltaic panel 2. In this way, during the movement of the photovoltaic panel 2, the distance between the sensor 1 and the panel surface of the photovoltaic panel 2 can be ensured to remain unchanged, which is beneficial to making the signal intensity received by the sensor 1 unchanged, ensuring the consistency of the detection accuracy of the sensor 1 during the entire movement process, and reducing the detection error.

[0081] In the third aspect, setting the first direction perpendicular to the second direction can not only reduce the time for the photovoltaic panel 2 to pass through each sensor 1, that is, reduce the detection duration and improve the detection efficiency, but also ensure that multiple sensors 1 cover the photovoltaic panel 2, which is beneficial to avoiding missed detection.

[0082] As Figure 1 shown, the position detection device 100 further includes a position adjustment component 3, and the position adjustment component 3 is used to drive a plurality of sensors 1 to move along the first direction.

[0083] Since the photovoltaic panels 2 of different sizes are likely to have different positions in the first direction, the position adjustment assembly 3 is used to drive the multiple sensors 1 to move in the first direction, facilitating the adjustment of the positions of the multiple sensors 1 in the first direction so that the multiple sensors 1 cover the entire photovoltaic panel 2 in the first direction, which is conducive to further avoiding the situation of missed detection.

[0084] Further, in a preferred embodiment, as Figure 1 shown, the position adjustment assembly 3 includes a driving member 31, a lead screw 32 and a fixed platform 33. The driving member 31 is used to drive the lead screw 32 to rotate around its own central axis, and the fixed platform 33 is in threaded cooperation with the lead screw 32. As Figure 4 shown, the multiple sensors 1 are arranged on the fixed platform 33.

[0085] Since the lead screw 32 and the fixed platform 33 in threaded cooperation with the lead screw 32 form a lead screw-nut mechanism, and since the lead screw-nut mechanism has high precision, the precise control of the position of the fixed platform 33 can be achieved, and thus the precise control of the positions of the multiple sensors 1 can be achieved.

[0086] For the driving member 31, in a preferred embodiment, the driving member 31 is a servo motor. Since the servo motor has a very high resolution and can achieve minute position adjustment, setting the driving member 31 as a servo motor enables the sensors 1 on the fixed platform 33 to be accurately positioned at the required detection positions, improving the precision of position adjustment.

[0087] In other embodiments, the driving member 31 can also be any one of a stepper motor, a cylinder and a hydraulic cylinder. The type selection of the driving member 31 is relatively flexible, and the embodiments of the present application do not make specific limitations thereto.

[0088] For the position adjustment assembly 3, in other embodiments, the position adjustment assembly 3 can also include an electric push rod, and the telescopic rod of the electric push rod is connected to the fixed platform 33, so that the multiple sensors 1 on the fixed platform 33 can be driven to move by the telescopic movement of the telescopic rod.

[0089] Since the electric push rod can be controlled by a simple electrical signal without a complex mechanical transmission system or hydraulic system, this makes the operation of the position adjustment assembly 3 more convenient.

[0090] Regarding the positional relationship between the sensors 1 and the photovoltaic panels 2, further, the multiple sensors 1 are used to be arranged within 5 mm - 20 mm directly above the photovoltaic panels 2.

[0091] With such a setting, it is beneficial to make the sensor 1 have a relatively low setting height, which not only facilitates the maintenance and debugging of the sensor 1, but also facilitates the fixing and installation of the sensor 1.

[0092] Regarding the distance between the sensor 1 and the photovoltaic panel 2, in the embodiments of the present application, the sensor 1 can be set within any value within the range of 5 mm, 20 mm or 5 mm - 20 mm directly above the photovoltaic panel 2. The distance between the sensor 1 and the photovoltaic panel 2 is set flexibly, and the embodiments of the present application do not make specific limitations on this.

[0094] The present application also provides a photovoltaic recovery device, as Figure 5 shown. The photovoltaic recovery device includes a position detection device 100. The structure of the position detection device 100 is the same as that of any one of the position detection devices 100 in the above embodiments, and can bring the same or similar beneficial effects. For details, reference can be made to the descriptions in the above embodiments, and the details will not be repeated in this embodiment.

[0095] In the present application, by setting equal intervals between any two adjacent sensors 1 and / or setting the intervals to be less than a preset distance, it is beneficial to reduce the length of the remaining wiring, beneficial to increase the recovery length of the wiring, and thus beneficial to reduce waste.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
