[0027] The technical solution of the present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0028] See also Figure 1-7 The present invention provides a technical solution: an active heat dissipation device for data acquisition, comprising a data acquisition device 2 and a mounting bracket 1 for fixing the data acquisition device 2. A ventilation hole is arranged at the bottom of the data acquisition device 2. In this application, the data acquisition device 2 adopts a conventional device in the art, and a sensor for detecting temperature is usually arranged inside the device. The active heat dissipation mechanism 3 is added on the top to realize the heat dissipation and ventilation of the data acquisition device 2 during operation.

[0029] An active heat dissipation mechanism 3 is detachably installed on the top of the data acquisition device 2, wherein the top of the data acquisition device 2 is hollow and directly connected to the active heat dissipation mechanism 3 through a flange. The active heat dissipation mechanism 3 blows air from the top of the data acquisition device 2 and blows it out from the ventilation holes at the bottom of the data acquisition device 2, forming flowing wind inside the data acquisition device 2 to reduce the temperature inside the data acquisition device 2.

[0030] The active heat dissipation mechanism 3 is composed of a cover plate 32 and a heat dissipation bottom cover 31 distributed up and down. The heat dissipation bottom cover 31 is a hollow annular structure. An annular slide rail 3101 is fixedly connected to the inner circle of the heat dissipation bottom cover 31. A heat dissipation bracket 33 with adjustable length is distributed on the annular slide rail 3101. The heat dissipation bracket 33 is composed of a plurality of movable cross-hinged connecting frames 331, and a rotating shaft of a motor 36 is fixedly connected to one end of the heat dissipation bracket 33. The motor 36 is fixedly installed on the cover plate 32.

[0031] A fixed block 3102 and a sliding block 3103 are respectively provided in the annular slide rail 3101, wherein the fixed block 3102 is fixedly installed on the annular slide rail 3101, and the sliding block 3103 can slide arbitrarily along the annular slide rail 3101, and the two ends of the heat dissipation bracket 33 are respectively hinged on the fixed block 3102 and the sliding block 3103. During the length extension and retraction process of the heat dissipation bracket 33, the sliding block 3103 slides along the track of the annular slide rail 3101.

[0032] Furthermore, a turntable 37 is fixedly provided at the end of the connecting frame 331 connected to the fixed block 3102, and the middle of the turntable 37 is rotatably mounted on the fixed block 3102 through a pin shaft, and the turntable 37 located on the upper side is fixedly connected to the driving shaft of the motor 36. It should be noted that since the two ends of the heat dissipation bracket 33 are respectively connected to the fixed block 3102 and the sliding block 3103, and ventilation is not required, the connecting frames 331 at the two ends do not need to be connected by a connecting shaft 332, and a conventional pin shaft in the art can be directly used.

[0033] The motor 36 in the present invention adopts a high-torque and low-speed motor. When the motor 36 rotates, it drives one of the connecting frames 331 close to the fixed block 3102 to rotate, so that the entire heat dissipation bracket 33 performs a scissor-like cross movement, and the heat dissipation bracket 33 is synchronously extended and retracted. At the same time, the annular slide rail 3101 is used to limit the active end of the heat dissipation bracket 33, so that it can only be extended and retracted along the trajectory of the annular slide rail 3101, so that the heat dissipation bracket 33 can be synchronously extended and retracted and annularly slid in the heat dissipation bottom cover 31, and the coverage range of the air hole 331b at the bottom of the connecting frame 331 is adjusted.

[0034] like Figure 4 As shown, multiple connecting frames 331 are interconnected, and air holes 331 b are provided at the bottom of the connecting frames 331 ; the top of the connecting frames 331 is connected to the air outlet of the blower 35 through a hose 34 , and the blower 35 is fixedly installed above the cover plate 32 .

[0035] The heat dissipation bracket 33 also includes a connecting shaft 332 for movably connecting two adjacent connecting brackets 331 and making them communicate with each other. The two adjacent connecting brackets 331 are cross-arranged, and their ends are rotatably connected by the connecting shaft 332, thereby forming a scissor-type heat dissipation bracket 33.

[0036] An air cavity 331a is provided inside the connecting frame 331, and an air hole 331b is located at the bottom of the air cavity 331a; an independent connecting tube 331c is provided at the position where the connecting frame 331 is connected to the connecting shaft 332, and an inner through hole 331d is provided on the side wall of the connecting tube 331c to communicate with the air cavity 331a.

[0037] The connecting shaft 332 is composed of a shaft body 332a and shaft end covers 332c arranged on both sides of the shaft body 332a. The shaft body 332a movably passes through the connecting tubes 331c on the two cross-arranged connecting frames 331, and an outer through hole 332b corresponding to the inner through hole 331d is also opened on the side wall of the shaft body 332a. The adjacent two connecting frames 331 are connected through the connecting shaft 332.

[0038] The shaft end cap 332c is sleeved on both sides of the shaft body 332a through a threaded structure, so that two adjacent connecting frames 331 can rotate around the shaft body 332a. Any shaft end cap 332c is connected to a hose 34 to conduct the wind from the outlet of the blower 35 to each part of the heat dissipation bracket 33.

[0039] In one embodiment of the present invention, in order to prevent the hose 34 from moving significantly in the heat dissipation bottom cover 31 , the communication port of the hose 34 may be disposed on a side close to the fixing block 3102 .

[0040] The outer through holes 332b on the shaft body 332a and the inner through holes 331d on the connecting frame 331 are both distributed in an annular shape. Meanwhile, during the rotation of the shaft body 332a and the connecting frame 331, the outer through holes 332b and the inner through holes 331d are always connected.

[0041] In the present invention, the heat dissipation bracket 33 can be adjusted on the heat dissipation bottom cover 31 under the drive of the motor 36. The active heat dissipation mechanism 3 is adjusted in time according to the temperature in the data acquisition device 2: when a larger air inlet area is required, the motor 36 can be controlled to rotate, the entire heat dissipation bracket 33 can be extended and distributed in the middle of the heat dissipation bottom cover 31, and the data acquisition device 2 below can be blown directly; when heat dissipation is not required, the motor 36 is reversed, and the heat dissipation bracket 33 can be retracted and folded to one side of the fixed block 3102 to reduce the air inlet area.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
