For example, they can be fixedly connected, detachably connected, or integrally connected; they can be mechanically connected or electrically connected; they can be directly connected or indirectly connected through an intermediate medium, or they can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Example: See Figures 1-8An energy-saving central air-conditioning fresh air system device includes a base 1, a support column 11 is provided at the upper end of the base 1, a sleeve 12 is provided at the upper end of the support column 11, and an adjustment block 15 is provided on the inner wall of the sleeve 12. A fixed block 13 is provided at one end of the adjustment block 15, and a docking block 14 is provided at the end of the fixed block 13 away from the adjustment block 15. A positioning component 3 is provided at the end of the docking block 14, and the sensing device is limited by the positioning component 3.

[0036] In this solution, the adjusting block 15 is spherical and is rotatably connected to the inner wall of the sleeve 12, so that when the docking block 14 is subjected to force, it can be rotated around the inner wall of the sleeve 12 through the adjusting block 15. At the same time, the lower end of the support column 11 is rotatably connected to the upper end of the base 1, thereby supporting the sleeve 12 and ensuring the overall stability of the docking block 14.

[0037] At the same time, an adjusting rod 16 is rotatably mounted on the lower end of the docking block 14, and the lower end of the adjusting rod 16 is rotatably connected to the upper end of the base 1. At the same time, both ends of the adjusting rod 16 are spherical, so as to facilitate support for the docking block 14 when it moves.

[0038] Furthermore, an adjustment component 2 is assembled on the upper end of the base 1 , and the position and angle of the sensing device are adjusted by the adjustment component 2 .

[0039] Among them, the adjustment component 2 includes a base plate 21 connected to the base 1, a positioning rod 22 is provided at the upper end of the base plate 21, a limiting block 23 is provided at the end of the positioning rod 22, and a sphere 24 is provided at the end of the limiting block 23 away from the positioning rod 22, and the outer surface of the sphere 24 is rotatably connected to the inner wall of the limiting block 23.

[0040] In this embodiment, the cross-section of the base plate 21 is L-shaped, and a through hole is provided on one side of the base plate 21. The inner wall of the through hole is slidably connected to the outer surface of the positioning rod 22, thereby limiting the positioning rod 22 and providing support for the movement of the positioning rod 22, ensuring that the positioning rod 22 will not fall off during use.

[0041] At the same time, a groove is provided at one end of the limit block 23, and the inner wall of the groove is rotatably connected to the outer surface of the sphere 24. The size of the groove is adjusted by rotating rods on both sides of the limit block 23. One end of the rotating rod passes through and extends to the other end of the limit block 23, and the outer surface of the rotating rod is provided with a thread to facilitate adjustment of the size of the groove.

[0042] Furthermore, an extension rod 25 is provided on the outer surface of the sphere 24 , and a movable cylinder 26 is provided at one end of the extension rod 25 away from the sphere 24 . A limiting rod 261 is provided on the outer surface of the movable cylinder 26 , and the upper end of the limiting rod 261 is connected to the lower end of the docking block 14 .

[0043] Specifically, the sphere 24 cooperates with the extension rod 25 to drive the movable cylinder 26 to move, thereby driving the limiting rods 261 arranged on both sides of the movable cylinder 26 to move. Since the upper end of the limiting rod 261 is connected to the docking block 14, the docking block 14 can be synchronously driven to adjust when the movable cylinder 26 moves, so that it is suitable for the current scene, and the angle of the positioning component 3 can be accurately adjusted, so that the detection equipment installed on the positioning component 3 can accurately monitor the air outlet conditions.

[0044] Furthermore, an arc block 28 is slidably mounted on the inner wall of the movable cylinder 26 , and a plurality of groups of protrusions 281 are provided on the outer surface of the arc block 28 , and the plurality of groups of protrusions 281 are evenly distributed on the outer surface of the arc block 28 .

[0045] A driving member 27 is provided at one end of the movable cylinder 26 away from the extension rod 25. The output end of the driving member 27 passes through and extends to the inner cavity of the movable cylinder 26. At the same time, a driving gear 271 is provided at the output end of the driving member 27. The outer surface of the driving gear 271 is engaged with the outer surface of the protrusion 281, and the movable cylinder 26 is driven to move by the driving gear 271.

[0046] Specifically, the driving member 27 is a device with power output such as a motor, and is connected to an external control device. When the driving member 27 is started, it synchronously drives the driving gear 271 arranged at its output end to rotate. Since the outer surface of the driving gear 271 is engaged with the outer surface of the protrusion 281, the driving gear 271 moves up and down on the arc block 28 when it rotates, and rotates around the sphere 24.

[0047] When the entire driving member 27 moves, the movable cylinder 26 is synchronously driven to move, so that the detection device is adjusted to be suitable for the current scene.

[0048] Furthermore, a sliding groove 211 is provided at the upper end of the bottom plate 21 and away from the positioning rod 22 , and a slider 29 is slidably mounted on the inner wall of the sliding groove 211 , and the upper end of the slider 29 is rotatably connected to the lower end of the arc block 28 .

[0049] Specifically, the inner cavity of the slide 211 can be provided with a component with telescopic function such as an electric telescopic rod, and connected to an external control device, and the end of the electric telescopic rod is connected to one side of the slider 29. The electric telescopic rod can drive the slider 29 to move telescopically, so that the arc block 28 set on the slider 29 can drive the movable cylinder 26 to adjust left and right to meet the detection requirements.

[0050] Furthermore, the positioning assembly 3 includes a clamping block 31 connected to the docking block 14. A baffle 32 is symmetrically provided at one end of the clamping block 31 away from the docking block 14. A power member 33 is provided at one end of each baffle 32 away from each other, and the output end of the power member 33 passes through and extends to the other end of the baffle 32.

[0051] In this embodiment, the clamping block 31 is installed on the docking block 14, and its power part 33 is a device with telescopic function such as an electric telescopic rod, and is connected to an external control device. At the same time, when the power part 33 is started, it synchronously drives the power rod 34 set at its output end to perform telescopic movement.

[0052] Furthermore, a first movable rod 35 is symmetrically mounted on one end of the baffle 32 for rotational connection. A second movable rod 351 is rotatably mounted on the end of the first movable rod 35 away from the baffle 32. A protective rod 36 is provided at the rotational connection between the first movable rod 35 and the second movable rod 351. A power rod 34 is rotatably mounted on the end of the protective rod 36 away from the first movable rod 35. The end of the power rod 34 away from the protective rod 36 is connected to the output end of the power member 33.

[0053] Specifically, when the power member 33 is started, the power rod 34 is driven to perform telescopic movement, and at the same time, the protective rod 36 installed at the end of the power rod 34 is driven to move. Since the first movable rod 35 and the second movable rod 351 are rotatably installed at one end of the protective rod 36 away from the power rod 34, when the power rod 34 is extended or retracted, the distance between the first movable rod 35 and the second movable rod 351 is adjusted away from one end, thereby synchronously driving the push plate 37 to move.

[0054] Furthermore, slide bars 38 are provided on both sides of one end of the baffle 32. A push plate 37 is slidably mounted on the outer surface of the slide bar 38. One end of the push plate 37 is rotatably connected to the end of the second movable rod 351. A support plate 39 is provided in the middle of the end of the clamping block 31, and a clamping block 371 is provided on the end of the push plate 37 away from the second movable rod 351.

[0055] Specifically, the outer surface of the slide rod 38 is slidably connected to both ends of the push plate 37, and the distance of the push plate 37 on the slide rod 38 is synchronously adjusted by moving the first movable rod 35 and the second movable rod 351, so that the push plate 37 is always in the optimal position.

[0056] When the push plate 37 moves, it cooperates with the clamping block 371 to gradually reduce the distance between the push plate 37 and the support plate 39, and the outer surface of the clamping block 371 is provided with rubber or other anti-slip components, so that when the clamping block 371 fixes the fixing rod 372, the whole remains stable to avoid shaking.

[0057] Furthermore, a fixing rod 372 is provided between the clamping block 371 and the support plate 39 , and an adjustment plate 373 is provided at the end of the fixing rod 372 .

[0058] Specifically, the end of the adjustment plate 373 is provided with multiple groups of snap-in grooves, and the inner wall of each snap-in groove is provided with elastic components such as springs, so that when the detection device is placed in the inner cavity of the snap-in groove, the detection device will not shake, thereby ensuring the accuracy of the detection data.

[0059] The control device can be a single-chip microcomputer (MCU). In this embodiment, the MCU is a typical embedded microcontroller, consisting of an arithmetic unit (APU), a controller, memory, and input / output devices, effectively acting as a miniature computer. Compared to general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its greatest advantages are its small size, allowing it to be placed inside the instrument, low memory capacity, simple input / output interfaces, and low power consumption.

[0060] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
