Description

Technical Field

[0001] The present invention relates to the field of angle adjustment of a heat collecting plate, and in particular to an adaptive angle adjustment system and method for a heat collecting plate. Background Art

[0002] A heat collector is a device that uses the energy in the surrounding environment to absorb and convert it into heat for heating. Currently, the heat collector is mainly a solar heat collector that collects light energy from the environment, which is widely used in solar water heaters.

[0003] Traditional solar collectors are generally fixedly installed, but as the sun moves, the incident angle of sunlight on the surface of the collector changes. Only when the incident angle of sunlight is 90° can the collector efficiency reach its maximum. In other words, for traditional collectors, the maximum collection efficiency can only be achieved for a very short period of time in a day, and the sun's energy cannot be effectively utilized.

[0004] Therefore, it is necessary to design an adaptive angle adjustment system and method for a solar collector to solve the problem of low solar collection efficiency of traditional solar collectors. Summary of the invention

[0005] In view of this, the present invention proposes an adaptive angle adjustment system and method for a heat collecting plate to solve the problem of low heat collecting efficiency of a traditional heat collecting plate.

[0006] In one aspect, the present invention provides an adaptive angle adjustment system for a heat collecting panel, comprising:

[0007] Angle adjustment module, used to adjust the angle of the heat collecting plate up and down or left and right;

[0008] The first light collection module is arranged on the upper and lower sides of the heat collecting plate, and is used to collect the light intensity on the upper and lower sides of the heat collecting plate;

[0015] Correction module: When the difference in light intensity above and below the solar collector or the difference in light intensity between the left and right sides is greater than the maximum preset difference, the correction module collects the longitude and latitude and altitude information of the solar collector, and then the control module corrects the angle of the solar collector according to the longitude and latitude, altitude and time.

[0019] When L1>L2 and ΔL≥ΔL3, the control module controls the angle adjustment module to rotate the heat collecting plate upward, and the rotation angle is R3.

[0020] Further, when L1<L2 and ΔL2>ΔL≥ΔL1, the control module controls the angle adjustment module to rotate the heat collecting plate downward, and the rotation angle is R1;

[0022] When L1>L2 and ΔL≥ΔL3, the control module controls the angle adjustment module to rotate the heat collecting plate downward, and the rotation angle is R3.

[0023] Furthermore, the light intensity on the left side of the solar collector collected by the second light collection module is T1, and the light intensity on the right side is T2; the control module calculates the difference ΔT between T1 and T2, and the control module is preset with the second light intensity difference ΔT1, ΔT2 and ΔT3, and ΔT1<ΔT2<ΔT3; the angle adjustment module is preset with the upper and lower rotation angles K1, K2 and K3, and R1<R2<R3;

[0024] When T1>T2 and ΔT2>ΔT≥ΔT1, the control module controls the angle adjustment module to rotate the heat collecting plate to the left, and the rotation angle is K1;

[0025] When T1>T2 and ΔT3>ΔT≥ΔT2, the control module controls the angle adjustment module to rotate the heat collecting plate to the left, and the rotation angle is K2;

[0026] When T1>T2 and ΔT≥ΔT3, the control module controls the angle adjustment module to rotate the heat collecting plate to the left, and the rotation angle is K3.

[0027] Further, when T1<T2 and ΔT2>ΔT≥ΔT1, the control module controls the angle adjustment module to rotate the heat collecting plate to the right, and the rotation angle is K1;

[0028] When T1<T2 and ΔT3>ΔT≥ΔT2, the control module controls the angle adjustment module to rotate the heat collecting plate to the right, and the rotation angle is K2;

[0029] When T1<T2 and ΔT≥ΔT3, the control module controls the angle adjustment module to rotate the heat collecting plate to the right, and the rotation angle is K3.

[0030] Further, when L1>L2 and ΔL<ΔL1, the angle adjustment module controls the heat collecting plate to rotate upward until ΔL=0;

[0031] When L1<L2 and ΔL<ΔL1, the angle adjustment module controls the heat collecting plate to rotate downward until ΔL=0;

[0034] Furthermore, the control module is preset with a maximum up-down light intensity difference A and a maximum left-right light intensity B, and A>ΔL3, B>ΔT3;

[0035] When ΔL>A or ΔT>B, the correction module collects the longitude and latitude and altitude information of the solar collector, and the control module corrects the angle of the solar collector according to the time, longitude and latitude and altitude information so that its surface faces the sun.

[0036] Furthermore, the control module also presets light intensity thresholds C and D and D>C. When L1, L2, T1 and T2 are all less than C, angle adjustment is stopped; when L1, L2, T1 and T2 are all greater than D, angle adjustment is started.

[0037] On the other hand, the present invention also proposes an adaptive angle adjustment method for a heat collecting plate, comprising:

[0039] Adjust the rotation direction and angle of the solar collector according to the difference in light intensity between the upper and lower sides and the left and right sides of the solar collector;

[0040] When the difference in light intensity between the upper and lower sides of the solar collector is greater than A or the difference in light intensity between the left and right sides is greater than B, the angle of the solar collector is corrected according to the longitude and latitude, altitude and time;

[0041] When the light intensity on the upper and lower sides and the left and right sides of the collector is less than C, stop the real-time angle adjustment.

On the contrary, the embodiments of the present application can be applied to any applicable scenario.

[0056] Reference Figure 1In some embodiments of the present application, an adaptive angle adjustment system for a heat collecting panel includes:

[0057] Angle adjustment module, used to adjust the angle of the heat collecting plate up and down or left and right;

[0058] The first light collection module is arranged on the upper and lower sides of the heat collecting plate, and is used to collect the light intensity on the upper and lower sides of the heat collecting plate;

[0059] The second light collection module is arranged on the left and right sides of the heat collecting plate, and is used to collect the light intensity on the left and right sides of the heat collecting plate;

[0060] A control module, used to receive the light intensity collected by the first light collection module and the second light collection module, and calculate the difference in light intensity between the upper and lower sides and the left and right sides of the heat collecting plate;

[0061] When the light intensity on the upper side of the heat collecting plate is greater than the light intensity on the lower side and the difference is greater than the preset difference, the control module controls the angle adjustment module to rotate the heat collecting plate upward;

[0062] When the light intensity on the upper side of the heat collecting plate is less than the light intensity on the lower side and the difference is greater than a preset difference, the control module controls the angle adjustment module to rotate the heat collecting plate downward;

[0063] When the light intensity on the left side of the heat collecting plate is greater than the light intensity on the right side and the difference is greater than the preset difference, the control module controls the angle adjustment module to rotate the heat collecting plate to the left;

[0064] When the light intensity on the left side of the solar collector is less than the light intensity on the right side and the difference is greater than the preset difference, the control module controls the angle adjustment module to rotate the solar collector to the right;

[0065] Correction module: When the difference in light intensity above and below the solar collector or the difference in light intensity between the left and right sides is greater than the maximum preset difference, the correction module collects the longitude and latitude and altitude information of the solar collector, and then the control module corrects the angle of the solar collector according to the longitude and latitude, altitude and time.

[0066] Specifically, the first light collection module is two light intensity sensors arranged on the upper and lower sides of the solar collector. Similarly, the second light collection module is two light intensity sensors arranged on the left and right sides of the solar collector. The correction module is arranged on the back of the solar collector, and has a built-in GPS device to obtain the longitude and latitude and altitude of the solar collector. The control module can receive the information collected by the first light collection module, the second light collection module and the correction module. At the same time, the control module has a built-in algorithm to calculate the temperature difference on the corresponding two sides of the solar collector, and can also calculate the sun angle according to the longitude and latitude, altitude and time.

[0067] It can be understood that the first light collection module and the second light collection module collect the light intensity of the solar collector in four directions in real time. When the difference is too large, the solar collector is rotated to a preset angle toward the side with greater light intensity, thereby ensuring that the surface of the solar collector faces the sun and improving the solar collection efficiency of the solar collector.

[0068] In some embodiments of the present application, the light intensity on the upper side of the solar collector collected by the first light collection module is L1, and the light intensity on the lower side is L2; ​​the control module calculates the difference ΔL between L1 and L2 in real time, and the control module is preset with the first light intensity difference ΔL1, ΔL2 and ΔL3, and ΔL1<ΔL2<ΔL3; the angle adjustment module is preset with the upper and lower rotation angles R1, R2 and R3, and R1<R2<R3;

[0069] When L1>L2 and ΔL2>ΔL≥ΔL1, the control module controls the angle adjustment module to rotate the heat collecting plate upward, and the rotation angle is R1;

[0070] When L1>L2 and ΔL3>ΔL≥ΔL2, the control module controls the angle adjustment module to rotate the heat collecting plate upward, and the rotation angle is R2;

[0071] When L1>L2 and ΔL≥ΔL3, the control module controls the angle adjustment module to rotate the heat collecting plate upward, and the rotation angle is R3.

[0072] When L1<L2 and ΔL2>ΔL≥ΔL1, the control module controls the angle adjustment module to rotate the heat collecting plate downward, and the rotation angle is R1;

[0073] When L1>L2 and ΔL3>ΔL≥ΔL2, the control module controls the angle adjustment module to rotate the heat collecting plate downward, and the rotation angle is R2;

[0074] When L1>L2 and ΔL≥ΔL3, the control module controls the angle adjustment module to rotate the heat collecting plate downward, and the rotation angle is R3.

[0075] Specifically, when the control module receives the light intensity information L1 and L2 collected by the first light collection module, it first calculates their difference, obtains the adjustment angle based on the difference, then determines the size of L1 and L2, and obtains the adjustment direction based on the size of L1 and L2.

[0076] It can be understood that when the sun moves, the upper and lower sides of the solar collector have different angles of incidence with the sunlight, so that the difference in light intensity received by the first light collection module on the upper and lower sides of the solar collector gradually increases. When the difference on both sides exceeds ΔL1, the solar collector is controlled to rotate toward the side with greater light intensity to ensure that the light intensity on its upper and lower sides does not exceed ΔL1; and the setting of ΔL2 and ΔL3 is mainly to deal with emergencies. For example, when an obstruction suddenly appears at the position of the solar collector, the difference in light intensity on both sides will suddenly increase, and then according to the increased difference, the solar collector is controlled to rotate to the side with greater light intensity to avoid the obstruction.

[0077] In some embodiments of the present application, the light intensity on the left side of the heat collecting plate collected by the second light collection module is T1, and the light intensity on the right side is T2; the control module calculates the difference ΔT between T1 and T2, and the control module is preset with the second light intensity difference ΔT1, ΔT2 and ΔT3, and ΔT1<ΔT2<ΔT3; the angle adjustment module is preset with the upper and lower rotation angles K1, K2 and K3, and R1<R2<R3;

[0078] When T1>T2 and ΔT2>ΔT≥ΔT1, the control module controls the angle adjustment module to rotate the heat collecting plate to the left, and the rotation angle is K1;

[0079] When T1>T2 and ΔT3>ΔT≥ΔT2, the control module controls the angle adjustment module to rotate the heat collecting plate to the left, and the rotation angle is K2;

[0080] When T1>T2 and ΔT≥ΔT3, the control module controls the angle adjustment module to rotate the heat collecting plate to the left, and the rotation angle is K3.

[0081] When T1<T2 and ΔT>ΔT1, the control module controls the angle adjustment module to rotate the heat collecting plate to the right, and the rotation angle is K1;

[0082] When T1<T2 and ΔT>ΔT2, the control module controls the angle adjustment module to rotate the heat collecting plate to the right, and the rotation angle is K2;

[0083] When T1<T2 and ΔT>ΔT3, the control module controls the angle adjustment module to rotate the heat collecting plate to the right, and the rotation angle is K3.

[0084] Specifically, when the control module receives the light intensity information T1 and T2 collected by the second light collection module, it also calculates their difference first, obtains the adjustment angle based on the difference, then determines the size of T1 and T2, and obtains the adjustment direction based on the size of T1 and T2.

[0085] In some embodiments of the present application, when L1>L2 and ΔL<ΔL1, the angle adjustment module controls the heat collecting plate to rotate upward until ΔL=0;

[0086] When L1<L2 and ΔL<ΔL1, the angle adjustment module controls the heat collecting plate to rotate downward until ΔL=0;

[0087] When T1>T2 and ΔT<ΔT1, the control module controls the angle adjustment module to rotate the heat collecting plate to the left until ΔT=0;

[0088] When T1<T2 and ΔT<ΔT1, the control module controls the angle adjustment module to rotate the heat collecting plate to the right until ΔT=0.

[0089] Specifically, the adjustment when ΔL>ΔL1 or ΔT>ΔT1 is the main adjustment, and can only rotate the preset angle, mainly to ensure that ΔL and ΔT are less than ΔL1 and ΔT1. The adjustment when ΔL<ΔL1 or ΔT<ΔT1 is the secondary adjustment after the main adjustment is completed. During the secondary adjustment, the solar collector rotates slowly until ΔL and ΔT are equal to 0, at which time the solar collector will face the sun. The secondary adjustment will only be performed after the main adjustment makes ΔL<ΔL1 or ΔT<ΔT1.

[0090] Specifically, when ΔL>ΔL1 or ΔT>ΔT1, a main adjustment is made to make ΔL<ΔL1 or ΔT<ΔT1. At this time, a secondary adjustment is started, and the collector rotates slowly until ΔL and ΔT are equal to 0 and then stops. Then, ΔL and ΔT continue to change as the sun shifts. At this time, although the conditions of ΔL<ΔL1 or ΔT<ΔT1 are met, no adjustment is made until ΔL>ΔL1 or ΔT>ΔT1. At this time, a main adjustment is made first to make ΔL<ΔL1 or ΔT<ΔT1, and then the secondary adjustment is made.

[0091] It can be understood that the setting of the secondary adjustment is mainly to optimize the adjustment frequency of the main adjustment and prevent repeated adjustments in a short period of time. For example, after the main adjustment on one side, ΔL and ΔL1 are very close. At this time, after a very short time, ΔL will be greater than ΔL1, resulting in repeated adjustments.

[0092] In some embodiments of the present application, the control module is preset with a maximum up-down light intensity difference A and a maximum left-right light intensity B, and A>ΔL3, B>ΔT3;

[0093] When ΔL>A or ΔT>B, the correction module collects the longitude and latitude and altitude information of the solar collector, and the control module corrects the angle of the solar collector according to the time, longitude and latitude and altitude information so that its surface faces the sun.

[0094] It is understandable that the correction module is mainly used to correct the solar collector when the solar collector deviates at an angle that is too large, such as when the equipment is started in the morning or restarted after maintenance.

[0095] In some embodiments of the present application, the control module is also preset with light intensity thresholds C and D and D>C. When L1, L2, T1 and T2 are all less than C, the device stops running; when L1, L2, T1 and T2 are all greater than D, the device starts.

[0096] It can be understood that when L1, L2, T1 and T2 are all less than C, it means that it is night and the heat collection efficiency is lower than the heat dissipation efficiency, so the angle adjustment is stopped; when L1, L2, T1 and T2 are all greater than D, it means that it is early morning and the heat collection efficiency is higher than the heat dissipation efficiency, so the angle adjustment is started.

[0097] In another preferred embodiment based on the above embodiment, refer to Figure 2 As shown, this embodiment provides an adaptive angle adjustment method for a heat collecting plate, comprising:

[0098] Collect the light intensity on the upper and lower sides and the left and right sides of the solar collector. When the light intensity on the upper and lower sides and the left and right sides of the solar collector is greater than D, start real-time angle adjustment, and then calculate the light intensity difference on the upper and lower sides and the left and right sides of the solar collector;

[0099] Adjust the rotation direction and angle of the solar collector according to the difference in light intensity between the upper and lower sides and the left and right sides of the solar collector;

[0100] When the difference in light intensity between the upper and lower sides of the solar collector is greater than A or the difference in light intensity between the left and right sides is greater than B, the angle of the solar collector is corrected according to the longitude and latitude, altitude and time;

[0101] When the light intensity on the upper and lower sides and the left and right sides of the collector is less than C, stop the real-time angle adjustment.

[0102] It is understandable that the above-mentioned adaptive angle adjustment system and method for a solar collector plate have the same beneficial effects, which will not be described in detail here.
