Technical Field

[0001] The invention relates to the technical field of thermal engineering detection, and in particular to a building thermal engineering detection heating device. Background Art

[0002] Building thermal testing is a test of indoor and outdoor heat, humidity, thermal environment and other parameters. The test content includes temperature, humidity and wind speed. These parameters can comprehensively evaluate the building. Among them, temperature measurement includes tests such as indoor and outdoor fixed temperature difference and indoor insulation effect. In this type of test, the indoor air needs to be heated and then the insulation effect is observed. This type of temperature test can directly reflect whether the building is suitable for living. Too low temperature difference means poor insulation effect, which needs to be rectified or renovated before it can be lived in. The building thermal detection and heating device in the existing technology cannot automatically heat the room and automatically measure the insulation time, and the degree of automation is insufficient. Summary of the invention

[0007] The device is moved by steering wheels and walking wheels. Move the device to the measured space. After ensuring that the space is closed, stick the external patch thermometer on the outdoor wall. The infrared thermometer is a point measuring device used to measure the indoor wall temperature at the corresponding position of the external patch thermometer. The infrared thermometer is a point measuring device used to measure the indoor wall temperature at the corresponding position of the external patch thermometer. After preparation, press the push rod to start the device. After the device is started, the control board controls the heating wire to start heating. The upper fan draws external air from top to bottom, and blows hot air out from the outlet pipe through the lower fan.

[0008] After the indoor heating, the readings of the infrared thermometer and the internal patch thermometer will rise. If the building insulation effect is poor, the reading of the external patch thermometer will also rise significantly. The readings of the infrared thermometer, the internal patch thermometer and the external patch thermometer are fed back to the control panel. The insulation effect of the building wall can be quickly obtained from the changes in the readings of the infrared thermometer, the internal patch thermometer and the external patch thermometer.

[0009] When the heating stops, the temperature inside the inner tube is lowered to the same level as the ambient temperature through the upper and lower fans. The ambient temperature is then detected through the temperature measuring tube, and the temperature and time are recorded on the temperature display. When the ambient temperature drops to the set temperature, the device stops working. The temperature displayed on the temperature display can be observed through the observation panel, and the timing time can be observed through the timing panel.

[0012] When the pressing rod is pressed, the pressing rod presses the lifting frame down through the pressing gear, the pressing spring is compressed, so that the pressing gear is meshed with the lower driving gear, the lower docking gear is meshed with the rotating gear, and the card wheel teeth jam the walking wheel, making the device unable to move. The lifting frame contacts the arc surface of the lower card block, pushes the card frame outward, and the transverse spring is compressed. Then the lifting frame reaches under the lower card block, and the lower card block prevents the pressing spring from rebounding. At this time, the lifting frame contacts the starting switch, and the internal motor starts, driving the lower driving gear to rotate, driving the pressing gear, the vertical gear shaft and the lower docking gear to rotate, and driving the central gear to rotate through the rotating gear. At this time, the upper docking gear is separated from the motor gear, and after the pressing rod is pressed, it rebounds and resets through the reset spring.

[0013] Further, the timing mechanism includes a docking gear rotatably installed in the outer shell, a lower digital display wheel, a middle digital display wheel and an upper digital display wheel are rotatably installed in the outer shell through a spiral spring, and numbers for marking time are printed on the lower digital display wheel, the middle digital display wheel and the upper digital display wheel, an upper gear and a lower gear are rotatably installed on the outer shell, a timing gear and a lower toothless gear are fixedly installed on the lower digital display wheel, a middle timing gear and an upper toothless gear are fixedly installed on the middle digital display wheel, an upper timing gear is fixedly installed on the upper digital display wheel, the timing gear is meshed with the docking gear, the lower toothless gear is meshed with the lower gear, the lower gear is meshed with the middle timing gear, the upper toothless gear is meshed with the upper gear, and the upper gear is meshed with the upper timing gear.

[0014] Furthermore, a vertical slider is slidably installed in the shell, the vertical slider is fixedly installed on the lifting frame, a pull rod is rotatably installed on the vertical slider, the pull rod is rotatably installed on the horizontal slider, an upper docking gear is rotatably installed on the horizontal slider, an upper gear is fixedly installed on the upper docking gear, an upper transfer gear is rotatably installed in the shell, a lower transfer gear is fixedly installed on the upper transfer gear, the lower transfer gear is meshed with the upper gear, an upper transmission belt is wrapped around the upper transfer gear and the docking gear, and when the lifting frame is not pressed down, the motor gear is meshed with the upper docking gear.

[0015] When the indoor temperature is heated to the specified temperature, the electric cylinder contracts once, pulling the bracket back, so that the lower clamping block releases the restriction of the lifting bracket, and the downward pressure spring rebounds, causing the lifting bracket to rise, driving the vertical slider to rise, thereby driving the pull rod to rotate, thereby driving the horizontal slider to slide toward the motor gear, so that the upper docking gear is engaged with the motor gear, and the inner motor does not stop rotating after being started. At this time, the lower docking gear is disengaged from the rotating gear, and the card wheel teeth are disengaged from the walking wheel. The inner motor drives the motor gear to rotate, thereby driving the upper docking gear and the upper gear to rotate, thereby driving the lower transfer gear and the upper transfer gear to rotate, thereby driving the docking gear to rotate through the upper transmission belt, thereby driving the timing gear, the lower digital display wheel and the lower missing tooth gear to rotate, and the lower missing tooth gear The toothed gear drives the lower gear to rotate, and the lower gear drives the middle timing gear, the middle digital display wheel and the upper toothless gear to rotate, and the upper toothless gear drives the upper gear to rotate, and the upper gear drives the upper timing gear and the upper digital display wheel to rotate. Since the lower toothless gear and the upper toothless gear are toothless, the speed of the lower digital display wheel is faster than the speed of the middle digital display wheel and the speed of the upper digital display wheel, so as to realize timing. When the upper digital display wheel, the middle digital display wheel and the lower digital display wheel rotate, the scroll spring on the inside thereof will be twisted. When the pressing rod is pressed for the next time, the lifting frame descends and drives the vertical slider to descend, thereby pulling the horizontal slider to slide outward through the pull rod, so that the upper docking gear is disengaged from the motor gear. At this time, the three scroll springs rebound and reset, driving the upper digital display wheel, the middle digital display wheel and the lower digital display wheel to reset.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) After the main mechanism of the present invention heats the room, if the building insulation effect is poor, the reading of the external patch thermometer will also increase significantly, and the readings of the infrared thermometer, the internal patch thermometer and the external patch thermometer are fed back to the control panel.

With the rotation of the center gear and the air outlet pipe, the heated air is evenly blown to the surroundings, thereby improving the heating efficiency; (3) The timing mechanism of the present invention can accurately time the indoor insulation situation. When the indoor temperature is heated to the set value, the timing mechanism starts. When the temperature drops to the set value, the internal motor stops. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The device is moved by the steering wheel 106 and the walking wheel 112 to move the device into the measured space. After ensuring that the space is closed, the external patch thermometer 107 is attached to the outdoor wall.

[0039] The pressing rod 113 is pressed down, and the pressing rod 113 presses the lifting frame 203 down through the pressing gear 206, and the pressing spring 214 is compressed, so that the pressing gear 206 is meshed with the lower driving gear 215, and the lower docking gear 207 is meshed with the rotating gear 208. The card wheel teeth 204 clamp the walking wheel 112, making the device unable to move. The lifting frame 203 contacts the arc surface of the lower clamping block 212, pushing the clamping frame 210 outward, and the transverse spring 211 is compressed. Then the lifting frame 203 reaches the lower clamping block. 212, the lower block 212 makes the downward pressure spring 214 unable to rebound. At this time, the lifting frame 203 contacts the starting switch 209, and the internal motor 201 is started, driving the lower driving gear 215 to rotate, driving the downward pressure gear 206, the vertical gear shaft 205 and the lower docking gear 207 to rotate, and driving the central gear 120 to rotate through the rotating gear 208.

[0041] like Figure 9-11 As shown, a vertical slider 309 is slidably installed in the shell 101, and the vertical slider 309 is fixedly installed with the lifting frame 203. A pull rod 308 is rotatably installed on the vertical slider 309, and the pull rod 308 is rotatably installed with the horizontal slider 301. An upper docking gear 302 is rotatably installed on the horizontal slider 301, and an upper gear 303 is fixedly installed on the upper docking gear 302. An upper transfer gear 305 is rotatably installed in the shell 101, and a lower transfer gear 304 is fixedly installed on the upper transfer gear 305.

When the lifting frame 203 is not pressed down, the motor gear 202 is meshed with the upper docking gear 302.

[0042] When the indoor temperature is heated to the specified temperature, the electric cylinder 213 contracts once, pulling the bracket 210 back, so that the lower clamping block 212 releases the restriction of the lifting frame 203, and the downward pressure spring 214 rebounds, so that the lifting frame 203 rises, driving the vertical slider 309 to rise, thereby driving the pull rod 308 to rotate, thereby driving the horizontal slider 301 to slide towards the motor gear 202, so that the upper docking gear 302 is meshed with the motor gear 202, and the inner motor 201 does not stop rotating after being started. At this time, the lower docking gear 207 is disengaged from the rotating gear 208, and the card wheel teeth 204 are disengaged from the walking wheel 112. The inner motor 201 drives the motor gear 202 to rotate, thereby driving the upper docking gear 302 and the upper gear 303 to rotate, thereby driving the lower transfer gear 304 and the upper transfer gear 305 to rotate, thereby driving the docking gear 307 to rotate through the upper transmission belt 306, thereby driving the timing gear 312, the lower digital display wheel 314 and the lower toothed gear 315 to rotate, and the lower toothed gear 31 5 drives the lower gear 310 to rotate, the lower gear 310 drives the middle timing gear 316, the middle digital display wheel 317 and the upper toothless gear 318 to rotate, the upper toothless gear 318 drives the upper gear 311 to rotate, the upper gear 311 drives the upper timing gear 319 and the upper digital display wheel 320 to rotate, because the lower toothless gear 315 and the upper toothless gear 318 are toothless, the rotation speed of the lower digital display wheel 314 is faster than the rotation speed of the middle digital display wheel 317 and the rotation speed of the upper digital display wheel 320, so that timing is realized. When the display wheel 320, the middle digital display wheel 317 and the lower digital display wheel 314 rotate, the scroll spring 313 on the inside thereof will be twisted. When the pressing rod 113 is pressed for the next time, the lifting frame 203 descends and drives the vertical slider 309 to descend, thereby pulling the horizontal slider 301 to slide outward through the pull rod 308, so that the upper docking gear 302 is disengaged from the motor gear 202. At this time, the three scroll springs 313 rebound and reset, driving the upper digital display wheel 320, the middle digital display wheel 317 and the lower digital display wheel 314 to reset.

[0043] Working principle: The device is moved by the steering wheel 106 and the walking wheel 112, and the device is moved to the measured space. After ensuring that the space is closed, the external patch thermometer 107 is attached to the outdoor wall. The infrared thermometer 110 is a point measuring device, which is used to measure the indoor wall temperature at the corresponding position of the external patch thermometer 107. The infrared thermometer 110 is a point measuring device, which is used to measure the indoor wall temperature at the corresponding position of the external patch thermometer 107. After preparation, press the pressing rod 113, and the pressing rod 113 presses the lifting frame 203 down through the pressing gear 206. The pressing spring 214 is compressed, so that the pressing gear 206 is meshed with the lower driving gear 215, and the lower docking gear 207 is meshed with the rotating gear 208. The card wheel teeth 204 jam the walking wheel 112, making the device unable to move. The lifting frame 203 contacts the arc surface of the lower card block 212, pushing the card frame 210 outward, and the transverse spring 211 After the lifting frame 203 is compressed, it reaches below the lower block 212. The lower block 212 makes the downward pressure spring 214 unable to rebound. At this time, the lifting frame 203 contacts the starting switch 209. At this time, the internal motor 201 starts, driving the lower driving gear 215 to rotate, driving the downward pressure gear 206, the vertical gear shaft 205 and the lower docking gear 207 to rotate, and driving the central gear 120 to rotate through the rotating gear 208. At this time, the upper docking gear 302 is separated from the motor gear 202. After the pressing rod 113 is pressed, it rebounds and resets through the reset spring 114. After the starting switch 209 contacts the lifting frame 203, the control board 121 controls the heating wire 122 to start heating, and the upper fan 117 draws external air from top to bottom, and blows hot air out from the outlet pipe 119 through the lower fan 118. With the rotation of the central gear 120 and the outlet pipe 119, the heated air is evenly blown to the surroundings to improve the heating efficiency.

[0044] After the indoor heating, the readings of the infrared thermometer 110 and the internal patch thermometer 109 will rise. If the building insulation effect is poor, the reading of the external patch thermometer 107 will also rise significantly. The readings of the infrared thermometer 110, the internal patch thermometer 109 and the external patch thermometer 107 are fed back to the control board 121. The insulation effect of the building wall can be quickly obtained from the changes in the readings of the infrared thermometer 110, the internal patch thermometer 109 and the external patch thermometer 107.

[0045] When the indoor temperature is heated to the specified temperature, the electric cylinder 213 contracts once, pulling the bracket 210 back, so that the lower clamping block 212 releases the restriction of the lifting frame 203, and the downward spring 214 rebounds, so that the lifting frame 203 rises, driving the vertical slider 309 to rise, thereby driving the pull rod 308 to rotate, thereby driving the horizontal slider 301 to slide toward the motor gear 202, so that the upper docking gear 302 is engaged with the motor gear 202. After the inner motor 201 is started, it does not stop rotating. At this time, the lower docking gear 201 07 is disengaged from the rotating gear 208, the card wheel tooth 204 is disengaged from the walking wheel 112, the inner motor 201 drives the motor gear 202 to rotate, thereby driving the upper docking gear 302 and the upper gear 303 to rotate, thereby driving the lower transfer gear 304 and the upper transfer gear 305 to rotate, thereby driving the docking gear 307 to rotate through the upper transmission belt 306, thereby driving the timing gear 312, the lower digital display wheel 314 and the lower toothless gear 315 to rotate, and the lower toothless gear 315 drives the lower gear 310 to rotate. The lower gear 310 drives the middle timing gear 316, the middle digital display wheel 317 and the upper toothless gear 318 to rotate, the upper toothless gear 318 drives the upper gear 311 to rotate, and the upper gear 311 drives the upper timing gear 319 and the upper digital display wheel 320 to rotate. Since the lower toothless gear 315 and the upper toothless gear 318 are toothless, the speed of the lower digital display wheel 314 is faster than the speed of the middle digital display wheel 317 and the speed of the upper digital display wheel 320, so that timing is realized. When the upper digital display wheel 320, the middle digital display wheel 317 and the lower digital display wheel 320 are When the digital display wheel 314 rotates, the scroll spring 313 inside it will be twisted, and the temperature inside the inner cylinder 116 will be reduced to the same as the ambient temperature through the upper fan 117 and the lower fan 118. Then the ambient temperature is detected through the temperature measuring tube 123, and the temperature and time are recorded on the temperature display 124. When the ambient temperature drops to the set temperature, the inner motor 201 stops rotating, and the temperature displayed on the temperature display 124 can be observed through the observation plate 102, and the timing time, that is, the heat preservation time, can be observed through the timing plate 103. When the pressing rod 113 is pressed for the next time, the lifting frame 203 descends and drives the vertical slider 309 to descend, thereby pulling the horizontal slider 301 outward through the pull rod 308, so that the upper docking gear 302 is separated from the motor gear 202. At this time, the three scroll springs 313 rebound and reset, driving the upper digital display wheel 320, the middle digital display wheel 317 and the lower digital display wheel 314 to reset.
