The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figure 1 to Figure 5 , which is the first embodiment of the present invention, and provides an indirect cooling system environment wind field detection device, comprising an installation unit 100, including a mounting frame 101, a positioning rod 102 arranged between two adjacent mounting frames 101, and a mounting shell 103 slidably arranged on the positioning rod 102;

[0030] The detection unit 200 includes a fixed shaft 201 rotatably disposed on one side of the mounting housing 103, a detection gear 202 fixedly disposed on the fixed shaft 201, an impeller 203 fixedly disposed on the fixed shaft 201, a rotation speed sensor 204 disposed on one side of the detection gear 202, and a wind amplification component 205 disposed outside the impeller 203;

[0031] The driving unit 300 includes a first connecting belt 301 disposed on one side of the mounting shell 103 and a winding assembly 302 disposed on one end of the first connecting belt 301;

[0032] The positioning unit 400 includes a transmission assembly 401 disposed in the mounting shell 103 , a trigger assembly 402 disposed on the output end of the transmission assembly 401 , and a positioning assembly 403 disposed on the trigger assembly 402 and the positioning rod 102 .

[0033] Furthermore, the wind amplification component 205 includes an air inlet pipe 205a, an air outlet pipe 205b arranged above the air inlet pipe 205a, and a tapered pipe 205c arranged between the air inlet pipe 205a and the air outlet pipe 205b.

[0034] Furthermore, the winding assembly 302 includes a mounting plate 302a disposed on the mounting frame 101, a positioning shaft 302b disposed in the inner cavity of the mounting plate 302a, and a spiral spring 302c disposed on the positioning shaft 302b, and one end of the spiral spring 302c is connected to one end of the first connecting belt 301.

[0035] It should be noted that the mounting unit 100 is composed of a mounting frame 101 and a positioning rod 102. There are two mounting frames 101, which are fixedly mounted at both ends of the positioning rod 102 respectively. The mounting shell 103 is slidably connected to the positioning rod 102 and is used to detect the wind force at different detection points. The detection unit 200 is used to detect the wind force, and is mainly composed of a wind amplification component 205, a speed sensor 204 for detecting the speed of the gear, an impeller 203 for sensing the wind force, and a detection gear 202. Specifically, the wind at the detection point is blown into the air inlet pipe 205a, along the cone The shaped tube 205c enters the air outlet pipe 205b, where the cross-section of the wind becomes smaller, thereby amplifying the wind force. The purpose of amplifying the wind force is to compensate for the force lost in driving the positioning unit. The winding component 302 is fixedly installed on the mounting frame 101, and its output end is fixedly connected to the first connecting belt 301, and one end of the first connecting belt 301 is connected to one end of the mounting shell 103. The positioning unit 400 is arranged on the mounting shell 103, and the detection gear 202 drives the trigger component 402 through the transmission component 401 to trigger the positioning component 403 to limit the travel distance of the mounting shell 103.

[0036] When in use, the device will be installed in the detection area through the mounting frame 101, and the first connecting belt 301 will be rolled up by the compressed spiral spring 302c, driving the mounting shell 103 to slide along the positioning rod 102. During the sliding of the mounting shell 103, the wind will enter the air outlet pipe 205b from the air inlet pipe 205a along the conical pipe 205c, and blow the impeller 203 to rotate. The impeller 203 drives the detection gear 202 to rotate, and the speed sensor 204 monitors the speed of the detection gear 202 to realize the judgment of the wind force. Since the mounting frame 101 slides along the positioning rod 102, the wind force detection at different detection points in the wind field is further realized, and during the movement of the mounting shell 103, under the action of the positioning unit 400, fixed-point detection can be realized.

[0037] In summary, the wind force is amplified by the wind force amplification component 205 and rotated by the impeller 203, and the wind force is detected by the speed sensor 204. The spiral spring 302c drives the mounting shell 103 to slide along the positioning rod 102, so that the wind force at different detection points in the wind field can be detected. Moreover, the present structure is simple, and the wind field detection length can be changed by only replacing the positioning rods 102 of different lengths. The positioning rod 102 is lower in cost than conventional linear modules and is easier to replace.

[0038] Example 2

[0039] Reference Figure 1 to Figure 5, which is a second embodiment of the present invention based on the first embodiment, includes a transmission assembly 401 including a transmission shaft 401a rotatably arranged in the mounting shell 103, a transmission gear 401b and a transmission wheel 401c respectively arranged at both ends of the transmission shaft 401a, a concentric shaft 401d arranged on one side of the mounting shell 103, a driven wheel 401e arranged on the concentric shaft 401d, and a first transmission belt 401f arranged on the transmission wheel 401c and the driven wheel 401e.

[0040] Furthermore, the trigger assembly 402 includes a half gear 402a disposed on the coaxial shaft 401d, a telescopic assembly 402b disposed in the mounting shell 103, and a rack 402c disposed at the extended end of the telescopic assembly 402b, the teeth of the rack 402c meshing with the teeth of the half gear 402a.

[0041] Furthermore, the telescopic assembly 402b includes a fixed tube 402b-1 disposed in the mounting shell 103, a limiting plate 402b-2 slidably disposed in the fixed tube 402b-1, a spring 402b-3 disposed below the limiting plate 402b-2, and a telescopic tube 402b-4 disposed on the upper surface of the limiting plate 402b-2.

[0042] Furthermore, the positioning assembly 403 includes a block 403 a disposed at the extending end of the telescopic assembly 402 b and a groove 403 b formed on the positioning rod 102 .

[0043] It should be noted that the transmission shaft 401a is rotatably connected to the mounting shell 103, and its two ends are respectively fixedly connected with a transmission gear 401b and a driven wheel 401c, the transmission gear 401b is meshed with the detection gear 202, and the transmission wheel 401c drives the driven wheel 401e to rotate through the first transmission belt 401f, and the driven wheel 401 is fixedly mounted on the concentric shaft 401d, and the concentric shaft 401d is rotatably mounted on one side of the mounting shell 103, and a half gear 402a is also fixedly mounted on the concentric shaft 401d, and the half gear 402a is meshed with the rack 402c, and the travel distance of the rack 402c is controlled by the radius of the half gear and the tooth density between the rack and the half gear. The fixed tube 402b-1 is fixedly mounted in the inner cavity of the mounting shell 103, and the spring 402b-3 located in the fixed tube 402b-1 is in a compressed state, the number of grooves 403b on the positioning rod 102 is fixed, and the spacing distance is set by actual conditions.

[0044] When in use, the detection gear 202 rotates to drive the transmission gear 401b to rotate, and the transmission gear 401b drives the transmission wheel 401c to rotate through the transmission shaft 401a, and the transmission wheel 401 drives the driven wheel 401e to rotate through the first transmission belt 401f. Since the driven wheel 401e and the half gear 402a are both fixedly arranged on the concentric shaft 401d, the rotation of the driven wheel 401e will drive the half gear 402a to rotate. When the half gear 402a rotates, it will drive the rack 402c to move downward, further driving the telescopic tube 402b-4 to be fixed. When the fixed tube 402b-1 contracts, the telescopic tube 402b-2 contracts, which will drive the block 403a to gradually separate from the groove 403b. When the half gear 402a and the rack 402c are no longer engaged, the block 403a is separated from the groove 403b. At this time, the mounting shell 103 loses the fixed point and will continue to move. The block 403a will be slidably connected with the positioning rod 102 until it enters the next groove 403b and the driven wheel 401c continues to rotate. When the rack 402c and the half gear 402a continue to engage, the previous operation will be repeated to achieve the effect of multi-point detection.

[0045] In summary, the mounting shell 103 is fixed to various fixed points on the positioning rod 102 by repeatedly engaging the block 403a and the groove 403b driven by wind force, and the entire process is affected by wind force. The positioning unit 400 can only be triggered by rotating the detection gear 202 a set number of times. The entire process will make the detection data more accurate.

[0046] Example 3

[0047] Reference Figure 1 to Figure 5 , which is a third embodiment of the present invention based on the first and second embodiments, includes a reset unit 500 , including a reset component 501 arranged on the mounting frame 101 , and a misalignment component 502 arranged on the mounting shell 103 .

[0048] Furthermore, the reset assembly 501 includes a second connecting belt 501a arranged on one side of the mounting shell 103, a winding disk 501b arranged on the mounting frame 101, a motor 501c arranged on the mounting frame 101, a trigger switch 501d arranged on the mounting frame 101, connecting wheels 501e respectively arranged on the motor 501c and the winding disk 501b, and a second transmission belt 501f arranged on the two connecting wheels 501e.

[0049] Furthermore, the offset assembly 502 includes a fixed rod 502a arranged above the mounting shell 103, a connecting frame 502b slidably arranged on the fixed rod 502a, a tension spring 502c arranged between the connecting frame 502b and the mounting shell 103, a limiting groove 502d opened on both sides of the mounting shell 103, a sliding rod 502e arranged below the mounting shell 103, an extrusion block 502f slidably arranged on the sliding rod 502e, a push plate 502g arranged on one side of the mounting frame 101, and a connecting frame 502h arranged on the lower surface of the mounting shell 103.

[0050] It should be noted that the winding reel 501b and the motor 501c are both fixedly mounted on the mounting frame 101, and the two are connected via a connecting wheel 501e and a second transmission belt 501f, one end of the second connecting belt 501a is connected to the winding reel 501b, and the other end is connected to the mounting shell 103, and a trigger switch for controlling the operation of the motor 501c is installed on the inner side of the two mounting frames 101, and a fixing rod 502a and a sliding rod 502e are also fixedly connected between the mounting frames 101 by screws, and the sliding rod 502e has irregular grooves, which can make the extrusion block 502f always vertical, and an inclined surface is provided on the extrusion block 502f.

[0051] During use, when the detection is about to contact, the installation shell 103 gradually approaches one of the installation frames 101, and the extrusion block 502f is squeezed and cannot continue to slide. The installation shell 103 is also subjected to tension, and the bottom edge of the connecting frame 502h slides along the inclined surface of the extrusion block 502f, while pulling the installation shell 103 to slide downward. The distance between the fixing rod 502a and the positioning rod 102 is fixed, so the installation shell 103 moves downward, and the positioning rod 102 slides upward in the limit groove 502d relative to the installation shell 103 until the extrusion block 502f is completely inserted into the connecting frame 502h, and the block 4 03a is separated from the groove 403b, and under the action of the tension spring 502c, the extrusion block 502f will be connected to the connecting frame 502h, and at the same time, the mounting shell 103 touches the trigger switch 501d to start the motor 501c. The motor 501c drives the winding disk 501b to reel up the second connecting belt 501a, and pulls the mounting shell 103 to reset. When the mounting shell 103 is about to be completely reset, the push plate 502g will be inserted into the connecting frame 502h, and the extrusion block 502f will be squeezed out of the connecting frame 502h. Finally, the mounting shell 103 touches the trigger switch 501d to turn off the motor 501c, so that the mounting shell 103 is reset.

[0052] In summary, the motor 501c is turned on and off by the mounting shell 103 hitting the two trigger switches 501d, so as to drive the mounting shell 103 to reset. During the resetting process, the extrusion block 502f will press down the mounting shell 103, so that the mounting shell 103 and the positioning rod 102 are relatively displaced, so that the positioning unit 400 and the positioning rod 102 are separated, and the resetting is completed and the connection is reconnected. The whole process does not require the operating system and manual intervention, so that the device can automatically and repeatedly detect the detection area.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
