DETAILED DESCRIPTION

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

[0031] Example 1

[0032] A heat dissipation device for a solar controller, such as Figure 1-Figure 5 As shown, it includes a square frame 1, a cylinder 2, a condenser 3, a blowing mechanism 4 and a clamping mechanism 5. The cylinder 2 is connected to the top center of the square frame 1, and the condenser 3 is connected inside the square frame 1. The condenser 3 is used for refrigeration. The cylinder 2 is provided with a blowing mechanism 4, and the blowing mechanism 4 can blow air to dissipate heat. The square frame 1 is provided with a clamping mechanism 5, and the clamping mechanism 5 can fix the square frame 1 on the solar controller.

[0033] like Figure 1 As shown, a handle 10 is also included, and the handles 10 are installed on the front and rear parts of the top of the square frame 1 through bolts.

[0034] like Figure 2 and Figure 4 As shown, the blowing mechanism 4 includes a mounting frame 41, a driving motor 42 and blades 43. The mounting frame 41 is welded inside the cylinder 2, the driving motor 42 is bolted to the mounting frame 41, and the output shaft of the driving motor 42 is connected to the blades 43.

[0035] like Figure 1 and Figure 5 As shown, the clamping mechanism 5 includes a mounting plate 51, a slide rod 52, a clamping plate 53 and a first elastic member 54. The mounting plates 51 are installed on the front and rear sides of the square frame 1 by bolts. The lower part of the mounting plate 51 is slidably connected with the slide rod 52. The inner end of the slide rod 52 is welded with a clamping plate 53. The clamping plate 53 is used to clamp the solar controller. The first elastic member 54 is connected between the clamping plate 53 and the adjacent mounting plate 51. The first elastic member 54 is a tension spring. The slide rod 52 passes through the first elastic member 54.

[0036] When using the device, the staff can use the handle 10 to move the device to a designated position so that the device is placed on the side of the solar controller away from the screen and the operation buttons. At this time, the clamping plates 53 are located on both sides of the solar controller. The staff then pushes the slide bar 52 to slide inward, and the slide bar 52 slides inward to drive the clamping plates 53 to move inward and clamp the solar controller. The first elastic member 54 is deformed. After the clamping plates 53 clamp the solar controller, the staff uses a tool to fix the position of the slide bar 52 so that the clamping plates 53 keep clamping the solar controller, thereby fixing the device on the solar controller. When the solar controller needs to be cooled, the staff starts the drive The motor 42 drives the output shaft of the motor 42 to rotate, driving the blades 43 to rotate. The blades 43 rotate to suck the outside air into the cylinder 2, and then blow it into the square frame 1, and make cold air through the condenser 3, which is blown onto the solar controller from the bottom of the square frame 1, thereby achieving the purpose of blowing and heat dissipation. When heat dissipation is not needed, the staff turns off the drive motor 42. When the device needs to be removed from the solar controller, the staff releases the slide bar 52. Under the action of the first elastic member 54 resetting, the clamping plate 53 drives the slide bar 52 to slide outward and reset. After the clamping plate 53 moves outward, it no longer clamps the solar controller. At this time, the staff can remove the device from the solar controller.

[0037] Example 2

[0038] On the basis of Example 1, Figure 1 and Figure 6 As shown, it also includes a pulling mechanism 6, which can squeeze the sliding rod 52 to slide inward. The pulling mechanism 6 includes a slider 61, a first connecting plate 62, an L-shaped plate 63 and an insert plate 64. The lower part of the mounting plate 51 is slidably connected to the slider 61, and the first connecting plate 62 is rotatably connected to the slider 61. The inner side of the slider 61 is welded with an L-shaped plate 63, and the lower end of the first connecting plate 62 is rotatably connected to the insert plate 64, and the insert plate 64 is inserted into the adjacent sliding rod 52.

[0039] When the device is put on the solar controller, the square frame 1 moves from top to bottom, and the square frame 1 moves downward and drives the entire pulling mechanism 6 to move downward through the mounting plate 51. When the L-shaped plate 63 moves downward to contact the solar controller, the square frame 1 continues to move downward, causing the solar controller to squeeze the L-shaped plate 63 to move upward. The L-shaped plate 63 moves upward and drives the slider 61 to slide upward on the mounting plate 51. The slider 61 slides upward and drives the plug plate 64 to move inward through the first connecting plate 62. The plug plate 64 moves inward and drives the slide bar 52 to slide inward, thereby driving the clamping plate 53 to move inward to clamp the solar controller. The first elastic member 54 is deformed. When the clamping plate 53 clamps the solar controller, the gravity of the upper structure of the device When the clamp 53 needs to be loosened, the staff pulls the plug plate 64 upward and no longer inserts it into the slide bar 52. At this time, the slide bar 52 is no longer restricted by the plug plate 64. Under the action of the first elastic member 54 resetting, the clamp 53 drives the slide bar 52 to slide outward and reset. After the device is removed from the solar controller, the staff pushes the slider 61 to slide downward, and then drives the plug plate 64 to move downward and reset and reinsert it into the slide bar 52 through the first connecting plate 62. When the slider 61 slides downward, it also drives the L-shaped plate 63 to move downward and reset. In this way, the clamp 53 can automatically clamp the solar controller when the square frame 1 moves downward.

[0040] like Figure 1 and Figure 7 As shown, it also includes a closing mechanism 7, which can block the bottom of the square frame 1. The closing mechanism 7 includes a guide rod 71, a sliding frame 72, a second elastic member 73, a mounting rod 74, a wedge block 75 and a closing frame 76. The right side of the square frame 1 is symmetrically welded with guide rods 71 ​​on the front and back, and a sliding frame 72 is slidably connected between the front and rear guide rods 71. The second elastic member 73 is connected between the sliding frame 72 and the guide rod 71. The second elastic member 73 is a compression spring. A mounting rod 74 is welded on the front side of the sliding frame 72, and a wedge block 75 is welded on the lower part of the mounting rod 74. The front L-shaped plate 63 moves upward to contact the wedge block 75. A closing frame 76 is welded on the lower part of the sliding frame 72, and the closing frame 76 fits the bottom of the square frame 1.

[0041] When the locking cam 72 is in the state of being lifted up, the locking cam 72 is in the state of being lifted up and locked, and the locking cam 72 is in the state of being unlocked and locked.

[0042] like Figure 1 and Figure 8 As shown, it also includes an external heat dissipation mechanism 8, which can disperse cold air. The external heat dissipation mechanism 8 includes an air outlet pipe 81, a conical cover 82, a stopper 83, a second connecting plate 84, a first mounting block 85, a third elastic member 86, a vertical plate 87 and a pushing block 88. Three air outlet pipes 81 are connected to the lower right side of the square frame 1, and a conical cover 82 is connected between the bottoms of the three air outlet pipes 81. The upper parts of the air outlet pipes 81 are all slidably connected with stoppers 83, and a second connecting plate 84 is welded between the right sides of the three stoppers 83. Three first mounting blocks 85 are equidistantly welded on the second connecting plate 84, and third elastic members 86 are connected between the first mounting blocks 85 and adjacent air outlet pipes 81. The third elastic member 86 is a tension spring, and vertical plates 87 are symmetrically welded on the top of the second connecting plate 84. Pushing blocks 88 are symmetrically welded on the upper part of the sliding frame 72, and the pushing blocks 88 move to the right and contact with the adjacent vertical plates 87.

[0043] When the device is used, the sliding frame 72 slides to the right and drives the pushing block 88 to move to the right. When the pushing block 88 moves to the right and contacts the vertical plate 87, the pushing block 88 continues to move to the right and drives the vertical plate 87 to move to the right. The vertical plate 87 moves to the right and drives the second connecting plate 84 to move to the right. The second connecting plate 84 moves to the right and drives the first mounting block 85 to move to the right. The third elastic member 86 is deformed. The second connecting plate 84 moves to the right and drives the stopper 83 to slide to the right and no longer blocks the air outlet pipe 81. At this time, The cold air inside the square frame 1 then enters the conical cover 82 through the air outlet pipe 81, and is sprayed to one side of the solar controller through the conical cover 82 to cool the wires connected to the solar controller. When the sliding frame 72 slides to the left, the pushing block 88 moves to the left and no longer squeezes the vertical plate 87. At this time, under the action of the third elastic member 86 resetting, the first mounting block 85 then drives the second connecting plate 84 to move to the left and reset. The second connecting plate 84 moves to the left and drives the stopper 83 to slide to the left to block the air outlet pipe 81 again.

[0044] like Figure 1 , Fig. 9 and Fig.10 As shown, it also includes a dustproof mechanism 9, which can prevent dust from entering the cylinder 2. The dustproof mechanism 9 includes a second mounting block 91, a protective shell 92 and a filter screen 93. The second mounting block 91 is welded to the upper front part of the cylinder 2, and the protective shell 92 is rotatably connected to the second mounting block 91. The protective shell 92 is fitted to the top of the cylinder 2, and the filter screen 93 is connected to the upper inner part of the cylinder 2.

[0045] When using the device, the protective shell 92 can block the top of the cylinder 2 to prevent impurities from entering the cylinder 2, while the filter 93 can prevent dust from entering the cylinder 2. When the filter 93 needs to be cleaned, the staff can push the protective shell 92 to rotate upward on the second mounting block 91 to open it. After the filter 93 is cleaned, push the protective shell 92 to rotate downward to close it.

[0046] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
