Description

Technical Field

[0001] The invention belongs to the technical field of uranium exploration, and in particular relates to an automated lead chamber suitable for detecting radon using activated carbon. Background Art

[0002] Soil radon measurement is a radioactive geophysical prospecting method for uranium deposits, which measures radon concentrations in the soil and then delineates the area of ​​radon anomalies. Activated carbon adsorption radon measurement, as a cumulative soil radon measurement method, offers advantages such as stable radon concentrations and reliable data. As my country focuses on exploring concealed uranium deposits, it is playing a vital role.

[0003] Currently, commercial activated carbon radon detectors require manual measurement of each activated carbon sample during the measurement process. The door of the lead chamber where the samples are stored must be opened and closed manually, and the activated carbon samples must be manually placed in and out of the chamber. The placement and retrieval time of each activated carbon sample must also be manually entered. This process is inefficient, time-consuming, and prone to errors, limiting the widespread use of activated carbon radon detection methods. Therefore, it is necessary to research intelligent implementation and efficient detection methods for activated carbon radon detection, and develop an intelligent and efficient activated carbon radon detector to effectively improve the efficiency of activated carbon sample measurement. One way to achieve intelligent and efficient detection in activated carbon radon detectors is to develop an automated lead chamber whose door can be opened and closed automatically by a motor.

Then, insert the locking sleeve 12 from the bottom up into the vertical gear shaft 10 from the side of the vertical gear movable head.

[0072] Step 8: Install the motor base 16, motor cover 15, and brushless DC motor 17: Insert the shaft end of the brushless DC motor 17 through the center hole of the motor's top fixed end 57.

From then on, when the brushless DC motor 17 rotates, it will drive the vertical gear shaft 10 to rotate together.

[0078] Step 13: Manually Opening and Closing the Lead Chamber Hatch 3: When manually opening the lead chamber hatch 3, the horizontal gear 5 cannot drive the vertical gear 9 to rotate due to the large manual rotation torque of the brushless DC motor 17 when it is not powered. First, raise the locking sleeve 12 above the vertical gear shaft movable head 13, rotate the vertical gear shaft movable head 13 90 degrees to disengage it from the motor connecting shaft 14, pull the vertical gear shaft 10 downward to disengage the vertical gear 9 from the horizontal gear 5, and then manually open the lead chamber hatch 3. After closing the lead chamber hatch 3, first rotate the vertical gear shaft movable head 13 to be aligned with the vertical gear shaft 10, so that the vertical gear shaft movable head 13 supports the motor connecting shaft 14, and then insert the locking sleeve 12 from top to bottom onto the motor connecting shaft 14. Example

[0079] The brushless DC motor 17 is connected to a 36V DC power supply. After power is turned on, the brushless DC motor 17 rotates clockwise, thereby driving the motor connecting shaft 14 to rotate, and driving the vertical gear shaft 10 to rotate through the locking connecting sleeve 12, and then driving the vertical gear 9 to rotate. The vertical gear 9 drives the transverse gear 5 to rotate through the gear, and the transverse gear 5 drives the transverse gear shaft 6 to rotate, and then drives the lead chamber door 3 to open through the door connecting rod 4. When the lead chamber door 3 is fully opened, the power is disconnected.

[0080] The brushless DC motor 17 is reversely connected to the 36V DC power supply. After power is turned on, the brushless DC motor 17 rotates counterclockwise. The same as the above steps, the lead chamber door 3 is closed. When the lead chamber door is completely closed, the power supply is disconnected.
