Description

Technical Field

[0001] The invention belongs to the technical field of geological environment investigation, and in particular relates to a PID rapid screening intelligent core box for drilling cores for environmental investigation. Background Art

[0002] PID (Photoionization Detector) rapid screening of drill cores is an efficient detection method, mainly used for rapid analysis of drill cores to determine whether specific substances such as volatile organic compounds (VOCs) are present. When screening drill cores, the PID probe is placed close to the core surface. If there are volatile organic compounds in the core, they will be detected and the corresponding concentration value will be displayed.

[0003] During testing, open the lid of the core box and carefully place the PID probe close to the core surface, maintaining an appropriate distance between the probe and the core surface to ensure accurate detection of VOCs released from the core. Slowly move the probe at different positions on the core surface to obtain more comprehensive test data. Based on the test results, determine the content level and distribution of VOCs in the core.

[0004] The existing core box and PID equipment have poor compatibility. When the PID equipment is needed to detect whether there are volatile organic compounds in the core sample in the core box, the cover of the core box needs to be completely opened, and then the PID probe needs to be placed close to the surface of the core sample. This detection method has major disadvantages. For example, the core sample is completely exposed to the air and is easily contaminated by external environmental pollutants. The purity of the core sample is difficult to ensure, which affects the analysis results of the sample. At the same time, harmful substances that may be contained in the core sample leak into the external environment, causing harm to the operator and the surrounding environment. In order to obtain more comprehensive detection data, the PID equipment needs to be slowly moved to different positions on the core surface, but handheld movement is obviously not convenient enough, and the distance between the probe and the core surface is difficult to ensure, and the detection spacing is difficult to ensure. In addition, the existing core box has a relatively low level of intelligence and is generally a simple box body, and the detection data of the core sample is poorly intuitive.

[0005] To this end, we provide a PID rapid screening intelligent core box for environmental investigation drilling cores to solve the above problems. Summary of the Invention

[0032] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0033] Example 1

[0034] In order to solve the problem that the existing core box and PID detection equipment have poor compatibility, when the core sample in the core box needs to be tested by the PID detection equipment, the core box cover generally needs to be completely opened. At this time, the core sample is completely exposed to the air and is easily contaminated by external environmental pollutants. The purity is difficult to ensure. At the same time, harmful substances that may be contained in the core sample leak into the external environment, which is easy to cause harm to the operator and the surrounding environment. In addition, the handheld mobile PID detection equipment is not convenient. Please refer to Figure 1-Figure 2 The present invention provides an intelligent core box for PID rapid screening of cores for environmental investigation drilling, comprising a box body 1, which is provided with a plurality of equally spaced placement slots 101 for placing cores, and a box cover 2 is provided above each placement slot 101; a foldable pull plate 3 is slidingly provided on the top of the box cover 2, and a support frame 4 is provided in the middle of the pull plate 3, on which a PID device 5 for detecting volatile organic compounds released from the core and a high-definition camera 6 for photographing the appearance characteristics of the core are respectively installed, and the bottom ends of the probe of the PID device 5 and the high-definition camera 6 are both inserted into the placement slot 101, and the pull plate 3 drives the support frame 4 to move along the axis of the core to obtain detection data of each position of the core; a display screen 102 for real-time display of the detection data of the PID device 5 and the high-definition camera 6 is hinged at the edge of the box body 1. When it is necessary to perform a PID rapid screening on the core in the placement slot 101, the pull plate 3 is unfolded, the PID device 5 and the high-definition camera 6 are installed on the support frame 4 and inserted into the placement slot 101, and the pull plate 3 is pulled to move it along the box cover 2. The pull plate 3 drives the support frame 4 to move along the axis of the core, so that the probe of the PID device 5 and the high-definition camera 6 slowly move to different positions on the core surface to obtain more comprehensive detection data, and record the VOCs concentration value, core surface morphology and other data in real time through the display screen 102.

[0035] One end of the box cover 2 is hinged to the box body 1, and the other end is buckled with the box body 1, which makes it easy to open the box cover 2 so that the core can be placed individually in the placement slot 101; a handle 103 is provided at one end of the box body 1, and equipment slots 104 for placing the PID device 5 and the high-definition camera 6 are provided on both sides of the handle 103.

[0036] In order to accurately record the test data, such as Figure 4 As shown, the top of the box cover 2 is provided with a slot 201 that slidably engages the pull plate 3. A plurality of equally spaced label boxes 202 are located on one side of the slot 201. When the PID device 5 detects a location, it immediately records the detection data on the label inside the label box 202 at that location, facilitating subsequent detection at the same location and data comparison.

[0037] like Figure 4-Figure 5As shown, a power supply rail 203 is provided on the other side of the slide 201. Two electric sliders 204 are slidably mounted within the power supply rail 203, secured together by insulating rods. Both sliders 204 are equipped with data cables 205, one of which plugs into the PID device 5 and the other plugs into the HD camera 6. A second latching slot 206 is also provided on the side of the slide 201 for securing the connectors at the ends of the data cables 205. The power supply rail 203 is configured as an integrated data transmission rail. Inspection data from the PID device 5 and the HD camera 6 is input to the display screen 102 via the data cables 205 and the power supply rail 203. During operation, when the pull plate 3 moves, it drives the support frame 4, the PID device 5, and the HD camera 6 to move. The PID device 5 and the HD camera 6 each drive the electric sliders 204 along the power supply rail 203 via their respective data cables 205, ensuring that inspection data is promptly transmitted to the display screen 102 during movement of the PID device 5 and the HD camera 6.

[0038] In order to enable the PID device 5 and the high-definition camera 6 to detect each position of the core in the placement groove 101, and to avoid the placement groove 101 being exposed during the detection process, causing the core sample to be exposed to the air, such as Figure 4 As shown, the pull plate 3 comprises a main body 301 and two support plates 302 hingedly connected to the ends of the main body 301. The ends of the support plates 302 are provided with first slots 303, and the middle of the main body 301 is provided with a latch 304 that matches the first slots 303. The pull plate 3 is foldable to facilitate stowing the core box when transporting it. During movement, the pull plate 3 always closes the chute 201, preventing the core sample from being exposed to air and, therefore, from being contaminated by external pollutants. This prevents harmful substances that may be contained in the core sample from leaking into the external environment, potentially posing a hazard to operators and the surrounding environment.

[0039] In order to solve the problem that the moving length of the PID device 5 and the high-definition camera 6 is difficult to control, resulting in difficulty in ensuring the detection interval, difficulty in continuing to detect at the same position, and inconvenience in data comparison, such as Figure 6-Figure 7As shown, the bottoms of the main plate 301 and the support plate 302 are each provided with a plurality of equally spaced positioning slots 305. A positioning member 8 for fixed-length movement of the pull plate 3 is provided at the end of the box body 1 near the handle 103. The positioning member 8 comprises a fixed seat 801 and a movable rod 802 that movably extends through the fixed seat 801. The end of the movable rod 802 is provided with a positioning block 803 that matches the positioning slot 305. A spring 804 is sleeved on the movable rod 802 between the positioning block 803 and the fixed seat 801. When the pull plate 3 is pulled, the positioning slot 305 moves to the positioning block 803. Under the push of the spring 804, the positioning block 803 snaps into the positioning slot 305, thereby limiting further movement of the pull plate 3. When the pull plate 3 needs to be moved again, a greater force is applied to cause the positioning block 803 to leave the positioning slot 305. To facilitate the positioning block 803 leaving the positioning slot 305, the positioning slot 305 and the positioning block 803 are both shaped as isosceles trapezoids.

[0040] Example 2

[0041] On the basis of Example 1, in order to obtain more comprehensive detection data, the PID device 5 and the high-definition camera 6 need to be slowly moved to different positions on the core surface. However, handheld movement is obviously not convenient enough, and it is also difficult to ensure that the probe of the PID device 5 is in the best position from the core surface. Figure 3 As shown, the support frame 4 includes a base plate 401 that passes through and is fixed on the pull plate 3, and a vertical plate 403 hinged on the top of the base plate 401; two sliding sleeves 404 are slidably provided on the vertical plate 403 and locked by a top screw, and the two sliding sleeves 404 are hinged with horizontal plates 405 for installing the PID device 5 and the high-definition camera 6 respectively; the base plate 401 below the PID device 5 and the high-definition camera 6 is provided with a through hole 402 for the probe of the PID device 5 and the high-definition camera 6 to pass through, and a rubber plug is provided in the through hole 402, and a closed cover is provided on the side of the through hole 402; knobs for locking the hinge axis are provided on the side of the hinge axis between the vertical plate 403 and the base plate 401 and on the side of the hinge axis between the sliding sleeve 404 and the vertical plate 403. The support frame 4 is also foldable so that the core box can be folded when carried; when the PID device 5 and the high-definition camera 6 are installed, the PID device 5 is inserted into the top of the corresponding horizontal plate 405, and the high-definition camera 6 is snapped into the bottom of the corresponding horizontal plate 405, and then the position of the sliding sleeve 404 on the vertical plate 403 is adjusted until the probe of the PID device 5 is in the best position from the core surface to improve the accuracy of the detection data.

[0042] Example 3

[0043] On the basis of the first and second embodiments, in order to further improve the comprehensiveness of the detection data, as shown in FIG. Figure 1 、 Figure 8As shown, a limit assembly 7 for securing the core and driving its rotation is provided within the placement slot 101. The limit assembly 7 secures the core sample to prevent it from shaking during transport. The limit assembly 7 drives the core sample to rotate, allowing the PID device 5 and the high-definition camera 6 to detect various positions on the core sample cylinder.

[0044] The limiting assembly 7 includes a partition 701 and two first limiting rods 702 and two second limiting rods 703 that are movably passed through the partition 701; a slot 704 for adjusting the position of the second limiting rod 703 on the partition 701 is provided on the partition 701 where the second limiting rod 703 passes through, and a knob for locking it in the slot 704 is sleeved on the second limiting rod 703. The position of the second limiting rod 703 is adjustable, so that the limiting assembly 7 can adapt to the fixation of core samples of different diameters; a telescopic rod 705 for adjusting the position of the partition 701 in the placement groove 101 is provided between the center of the partition 701 and the end face of the placement groove 101, and a rotating part 706 is provided at the end of the telescopic rod 705. The rotating part 706 is rotatably arranged on the inner wall of the box body 1 and extends to the outside of the box body 1; a hole for the second limiting rod 703 to pass through is provided on the box body 1, and a closed cover is provided on the side of the hole.

[0045] When the core sample needs to be placed in the placement groove 101, the two second limiting rods 703 are pulled outward, and then the core sample is placed on the two first limiting rods 702, and then the position of the partition 701 is adjusted by the telescopic rod 705 so that it abuts against the end of the core sample, and then based on the diameter specification of the core sample, the position of the second limiting rod 703 on the partition 701 is adjusted and fixed; when the core sample needs to be rotated, the rotating part 706 is rotated, and the rotating part 706 drives the telescopic rod 705 to rotate, and the telescopic rod 705 drives the partition 701, the first limiting rod 702 and the second limiting rod 703 to rotate, and the first limiting rod 702 and the second limiting rod 703 drive the core sample to rotate.

[0046] The above embodiment merely represents one embodiment of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and such modifications and improvements are all within the scope of protection of the present invention.
