They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0023] like Figures 1 to 3 As shown, a human body sensing automatic damper teaching demonstration operation instrument includes a support frame 1, a simulated damper 2 is rotatably connected to the support frame 1, and a driving component and a sensing component are provided on the side of the support frame 1 away from the simulated damper 2. When the sensing component detects that someone is approaching the simulated damper 2, the driving component drives the simulated damper 2 to open.

[0024] This application uses a support frame 1 as the manufacturing structure, introduces a drive component, and uses a single-chip microcomputer control module. When people or objects appear during the operation of the equipment, the sensing component and the drive component cooperate to automatically open the simulated damper 2, achieving the purpose of demonstrating the actual control of the equipment. It makes it clear to students that they can learn the practical operation and maintenance knowledge of the mine automatic damper principle in the classroom without going to the underground site or workshop, and realizes intelligent functions. The overall size of the operating instrument is small and easy to carry for demonstration, which is convenient for students' practical learning, improves teaching efficiency, and eliminates the time of going up and down the workshop, saving a lot of production time for the mine and improving economic benefits.

[0025] Preferably, the control module program can be set to delay the automatic closing of the simulated damper 2 for 3 seconds after opening, so that the trainees can more intuitively feel the working condition of the damper sensing automatic opening and closing.

[0026] In the human body sensing automatic damper teaching demonstration operating instrument of this embodiment, the driving component includes a driving gear 3 fixedly connected to the simulated damper 2, and the driving gear 3 is rotatably connected to the supporting frame 1.

[0027] Specifically, the simulated damper 2 is fixedly connected to the driving gear 3 along the radial direction of the driving gear 3, and the rotating shaft of the simulated damper 2 and the driving gear 3 are in the same plane. In this application, the simulated damper 2 is driven to rotate or close on the front of the support frame 1 by the rotation of the driving gear 3. The structure is simple, and it is easy to achieve the closing and opening effects of the simulated damper 2, so that students can intuitively feel the working conditions of the damper.

[0028] Preferably, a base is provided on the outside of the support frame 1 to facilitate the placement of the operating instrument. The base is made of cardboard and the support frame 1 is made of plastic material. The two are glued and fixed. The simulated damper 2 is made of a plastic plate, which is light in weight and convenient for stable connection with the support frame 1. It is also easy to rotate. The present application is assembled by the above-mentioned parts, which is low in cost, safe and reliable, and has a low failure rate.

[0029] In the human body sensing automatic damper teaching demonstration operating instrument of this embodiment, the driving gear 3 is fan-shaped, and the driving gear 3 passes through the supporting frame 1 and is installed perpendicular to the supporting frame 1. A mounting hole is opened on the supporting frame 1.

[0030] Specifically, the driving gear 3 is set as a part of the complete gear, and the mounting hole matches the radius size of the driving gear 3, so that the driving gear 3 rotates while passing through and driving the mounting hole, simulating the damper 2 rotating on the support frame 1.

[0031] By setting a fan-shaped driving gear 3, the driving gear 3 is hidden on the back of the supporting frame 1. When rotating, the driving gear 3 can also be blocked by the simulated damper 2, thereby ensuring the aesthetics from the front perspective, while avoiding the driving gear 3 being exposed on the surface of the supporting frame 1 and being easily damaged by collision.

[0032] Preferably, the driving gear 3 is semicircular to ensure that the driving gear 3 can rotate at a sufficiently large angle.

[0033] In the human body sensing automatic damper teaching demonstration operating instrument of this embodiment, a rotating shaft 4 is fixedly connected between the two end faces of the driving gear 3, and any end face of the driving gear 3 is fixedly connected to the edge of the simulated damper 2.

[0034] Specifically, the rotating shaft 4 and the simulated damper 2 are in the same plane, so that the simulated damper 2 can rotate around the rotating shaft 4, thereby avoiding an angle between the simulated damper 2 and the supporting frame 1, which would cause a loose closure and affect normal teaching use.

[0035] In the human body sensing automatic damper teaching demonstration operating instrument of this embodiment, the rotating shaft 4 is inserted into the limiting column 5, and the limiting column 5 is located on the side of the supporting frame 1 away from the simulated damper 2. The limiting column 5 is provided with a movable groove for driving the gear 3 to rotate.

[0036] Specifically, a limiting column 5 is provided on the back of the supporting frame 1 , and the limiting column 5 limits the rotation axis of the rotating shaft 4 and the simulated damper 2 to ensure that the simulated damper 2 rotates smoothly to be opened or closed.

[0037] In the human body sensing automatic damper teaching demonstration operating instrument of this embodiment, the driving component also includes a driving gear 6 meshing with the driving gear 3, and the driving gear 6 is fixedly connected to the output end of the driving motor 7, and the driving motor 7 is fixed on the supporting frame 1.

[0038] A driving motor 7 and a driving gear 6 are provided, and transmission is achieved through gear meshing. The driving motor 7 rotates forward and reverse to drive the gear 3 to extend or retract the support frame 1, thereby achieving the closing and angle adjustment of the simulated damper 2.

[0039] In the human body sensing automatic damper teaching demonstration operating instrument of this embodiment, an air outlet is opened on the support frame 1, and the sensing component includes an infrared sensor 8 arranged opposite to the driving component, and the infrared sensor 8 is connected to the driving component signal.

[0040] Specifically, the infrared sensor 8 and the drive motor 7 are respectively connected to the control module. After the device is turned on, shake your hand, the infrared sensor 8 picks up the signal and inputs it into the microcontroller, and then outputs the start threshold signal to the drive motor 7, the execution element action (the simulated damper 2 is opened), and the control module is preferably set to control the simulated damper 2 to automatically close after 3 seconds.

[0041] In the human body sensing automatic damper teaching demonstration operating instrument of this embodiment, the sensing component further includes a light-emitting tube 9, and the light-emitting tube 9, the infrared sensor 8 and the driving component are respectively connected to the control unit for signal.

[0042] Specifically, the circuitry of the practical teaching device primarily consists of an inductive sensing circuit, an operational amplifier circuit, and a drive execution circuit. The integrated control system includes: an ITR20001, which serves as a conductive infrared photoelectric sensor and an infrared sensor switch in the distance-measuring circuit, installed on top of the teaching device's intelligent damper; an STM32F103R6, which serves as the main control core module, receives photoelectric infrared signal input, outputs action light indicators, and provides servo drive output functions. When an object passes within the ITR20001's detectable infrared signal emission angle and effective distance, the damper cover switch circuit is triggered, simulating the automatic opening and closing function of damper 2; and a KM-1218FN30-3, which drives the DC motor and operates with a 2-4V power supply.

[0043] In the human body sensing automatic damper teaching demonstration operating instrument of this embodiment, a strip groove is opened on one side of the support frame 1 where the simulated damper 2 is installed, and the infrared sensor 8 and the light-emitting tube 9 are respectively located in the strip groove.

[0044] Specifically, in addition to installing the infrared sensor 8 on the top of the device, it can also be set in the above-mentioned strip groove to facilitate the infrared sensor 8 to detect and the light-emitting tube 9 to emit light to remind the staff.

[0045] Working principle: During the teaching operation, use your palm to pass over the infrared sensor 8 (simulating the human body and underground vehicles passing through the damper). The infrared sensing circuit sensing area picks up the signal, transmits it to the single-chip microcomputer control circuit, outputs the signal to the drive circuit, and drives the motor 7 to drive the simulated damper 2 to move, completing the teaching principle of human body sensing automatic damper action.
