Description

Technical Field

[0001] This utility model relates to the technical field of radon detection equipment, specifically a radon detection device for coal samples with early warning function. Background Technology

[0002] Radon is a colorless and odorless radioactive gas. When inhaled, radon decays in the air, producing alpha particles. These particles continuously strike the surface of the respiratory tract, damaging lung cells, such as causing chromosome breakage. Radon also causes radiation damage to the respiratory system, potentially inducing lung cancer, leukemia, and other respiratory diseases. Radon is widely distributed in the Earth's crust, found in almost all types of rocks, and is prevalent in coal mines, soil, and coal samples. The amount of radon released from coal samples is an important indicator of the radiation level and safety of the coal.

[0003] The existing technology has the following shortcomings;

[0004] Existing radon detection equipment is mostly fixed or laboratory-type, with poor real-time performance and most of them lack automatic early warning functions. This results in radon leaks not being detected in time during coal sample transportation, storage, and testing, posing safety hazards. Furthermore, the sampling process is cumbersome, the response time is long, and real-time monitoring and early warning are not possible. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a radon gas detection device for coal samples with early warning function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coal sample radon gas detection device with early warning function, comprising a gas detection box, a fixing plate fixedly installed inside the gas detection box, a detachable top cover fixedly and movably installed on the top of the gas detection box, and an alarm and a display panel fixedly installed on the outside of the gas detection box.

[0007] As a preferred technical solution of this utility model, the interior of the gas detection box is divided into a receiving cavity and an installation cavity by a fixing plate. A partition is fixedly installed at the center of the installation cavity. A door is hinged to the gas detection box below the partition. Handles are fixedly installed on both the door and the top cover. A sealing transparent plate is embedded at the front end of the gas detection box corresponding to the receiving cavity.

[0008] As a preferred embodiment of this utility model, a power supply and controller are fixedly installed at the bottom of the mounting cavity corresponding to the partition, a radon gas detector is fixedly installed at the top of the mounting cavity corresponding to the partition, and the upper part of the mounting cavity corresponding to the partition is sealed.

[0009] As a preferred technical solution of this utility model, the mounting cavity is fixedly installed with a connecting pipe at the position corresponding to the radon gas detector, and a radon gas outlet pipe is sleeved on the outer surface of the connecting pipe. The other end of the radon gas outlet pipe is connected to the interior of the receiving cavity, and a fastening ring is sleeved on the radon gas outlet pipe at the position corresponding to the connecting pipe.

[0010] As a preferred embodiment of this utility model, the controller is electrically connected to the alarm, the display panel, and the radon detector, respectively, and a control switch for controlling the power supply is fixedly installed on the outside of the gas detection box.

[0011] As a preferred embodiment of this utility model, the top cover is fixedly installed with sealing blocks at the positions corresponding to the receiving cavity and the mounting cavity. The sealing blocks extend into the interior of the gas detection box and fit against the inner walls of the receiving cavity and the mounting cavity respectively. Furthermore, sealing rings are fixedly installed inside the receiving cavity and the mounting cavity.

[0012] As a preferred embodiment of this utility model, the controller has power detection and low power alarm functions, and the alarm includes a buzzer and an LED flashlight.

[0013] Compared with the prior art, this utility model provides a radon detection device for coal samples with early warning function, which has the following beneficial effects:

[0014] 1. This radon gas detection device for coal samples with early warning function, consisting of a top cover, sealing blocks, and a door, allows for easy removal of the top cover by pulling the handle. This enables staff to place the coal sample to be tested into the receiving chamber. After placing the coal sample, the top cover is reset. Simultaneously, two sets of sealing blocks are located inside the receiving chamber and the installation chamber, respectively, and are in contact with the sealing ring to seal the receiving chamber and the installation chamber, preventing radon gas leakage from the gas detection chamber and ensuring the airtightness of the detection chamber, thereby improving the stability and accuracy of the detection data. At the same time, the handle on the door allows for easy opening of the installation chamber below, facilitating the installation and maintenance of the internal components.

[0015] 2. This coal sample radon detection device with early warning function, during detection, fixes the end of the radon outlet pipe to the connecting pipe with a fastening ring, and starts the radon detector by controlling the switch. At this time, the radon gas released from the coal sample is transported to the interior of the installation cavity through the radon outlet pipe. The radon detector detects the radon concentration in real time, and when the concentration exceeds the set threshold, it transmits the detection signal to the controller. The controller then controls the buzzer and LED flashlight to provide sound and light alarms. It can promptly alarm when there is a problem with the data, and when the power is too low, the controller keeps the flashlight on to remind the staff. At the same time, the display panel displays the radon value detected by the radon detector in real time, so as to facilitate the observation and recording of the detection value.

[0016] 3. This radon detection device for coal samples with early warning function uses a fixing plate to divide the interior of the gas detection chamber into a receiving chamber and an installation chamber, effectively isolating the detection area from the coal sample storage area. Furthermore, by connecting pipes and a radon outlet pipe, when radon is released from the coal sample, the radon is transported to the interior of the installation chamber through the radon outlet pipe, creating a closed guiding channel between the receiving chamber and the radon detector. This allows the released radon from the coal sample to be efficiently introduced into the sensor area for collection, improving the response speed. Attached Figure Description
