Description

Technical Field

[0001] The invention belongs to the technical field of geological environment investigation, and in particular relates to a PID fast 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, which is mainly used for rapid analysis of drill cores to determine whether there are specific substances such as volatile organic compounds (VOCs) in them. 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 the test, open the lid of the core box, carefully bring the PID probe close to the core surface, maintain an appropriate distance between the probe and the core surface to ensure accurate detection of VOCs released from the core, and 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 is 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 at different positions on the core surface, but the handheld movement is obviously not convenient enough, 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 degree 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

DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here 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. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0033] Embodiment 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 detected by the PID detection equipment, the cover of the core box 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 guarantee. At the same time, the 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 enough. 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, on which are provided 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 slidably 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 the 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 rapid PID screening on the core in the placement slot 101, unfold the pull plate 3, install the PID device 5 and the high-definition camera 6 on the support frame 4, and insert them into the placement slot 101, pull the pull plate 3 to move it along the box cover 2, and 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 at 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 to 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 slide groove 201 that slides with the pull plate 3, and one side of the slide groove 201 is provided with a plurality of label boxes 202 that are evenly spaced. When the PID device 5 detects at a certain position, it immediately records the detection data on the label in the label box 202 at the position, so as to facilitate subsequent detection at the same position 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, and two electric sliders 204 fixed together by insulating rods are slidably provided in the power supply rail 203, and data lines 205 are provided on the two electric sliders 204, one data line 205 is plugged with the PID device 5, and the other data line 205 is plugged with the high-definition camera 6; a second card slot 206 for fixing the plug connector at the end of the data line 205 is also provided on the side of the slide 201. The power supply rail 203 is set as an electric rail with integrated data transmission function, and the detection data in the PID device 5 and the high-definition camera 6 are input into the display screen 102 through the data line 205 and the power supply rail 203; when in use, when the pull plate 3 moves, it drives the support frame 4, the PID device 5 and the high-definition camera 6 to move, and the PID device 5 and the high-definition camera 6 drive the electric slider 204 to move along the power supply rail 203 through their respective data lines 205, so as to ensure that the detection data can be transmitted to the display screen 102 in time during the movement of the PID device 5 and the high-definition 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 slot 101 and avoid the placement slot 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 includes a main body 301 and two support plates 302 respectively hinged at both ends of the main body 301; the end of the support plate 302 is provided with a first card slot 303, and the middle of the main body 301 is provided with a card block 304 matching the first card slot 303. The pull plate 3 is designed to be foldable so that the core box can be folded when carried, and the pull plate 3 can always close the slide 201 during the movement process to prevent the core sample from being exposed to the air, thereby preventing the core sample from being contaminated by external environmental pollutants, and the harmful substances that may be contained in the core sample leaking into the external environment, causing harm to the operator 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 bottom of the main body 301 and the supporting plate body 302 are both provided with a plurality of equally spaced positioning grooves 305, and the end of the box body 1 near the handle 103 is provided with a positioning member 8 for the fixed length movement of the pull plate 3; the positioning member 8 includes a fixed seat 801 and a movable rod 802 that movably penetrates the fixed seat 801, and the end of the movable rod 802 is provided with a positioning block 803 that matches the positioning groove 305, and 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 groove 305 moves to the positioning block 803, and under the push of the spring 804, the positioning block 803 is stuck in the positioning groove 305, thereby limiting the continued movement of the pull plate 3. When the pull plate 3 needs to move again, a large force is applied to make the positioning block 803 leave the positioning groove 305. In order to facilitate the positioning block 803 to leave the positioning groove 305, the shapes of the positioning groove 305 and the positioning block 803 are both set to be isosceles trapezoidal.

[0040] Embodiment 2

[0041] On the basis of the first embodiment, in order to obtain more comprehensive detection data, the PID device 5 and the high-definition camera 6 need to be slowly moved at different positions on the core surface, but hand-held movement is obviously not convenient enough, and it is also difficult to ensure that the probe of the PID device 5 is at the best position from the core surface, such as 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 hingedly provided 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 hole plug is provided in the through hole 402, and a closed cover plate 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 inserted 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 at the best position from the core surface to improve the accuracy of the detection data.

[0042] Embodiment 3

[0043] On the basis of the first and second embodiments, in order to further improve the comprehensiveness of the detection data, as Figure 1 , Figure 8As shown, a limiting assembly 7 for fixing the core and driving the core to rotate is provided inside the placement groove 101. The limiting assembly 7 fixes the core sample to prevent the core sample from shaking when the core box is carried and transported, and the limiting assembly 7 drives the core sample to rotate, so that the PID device 5 and the high-definition camera 6 can detect various positions of 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 movably passing 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 the second limiting rod 703 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 member 706 is provided at the end of the telescopic rod 705. The rotating member 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 limit rods 703 are pulled outward, and then the core sample is placed on the two first limit rods 702, and then the position of the partition 701 is adjusted by the telescopic rod 705 to make it abut against the end of the core sample, and then based on the diameter specification of the core sample, the position of the second limit rod 703 on the partition 701 is adjusted and fixed; when the core sample needs to be rotated, the rotating member 706 is rotated, and the rotating member 706 drives the telescopic rod 705 to rotate, and the telescopic rod 705 drives the partition 701, the first limit rod 702 and the second limit rod 703 to rotate, and the first limit rod 702 and the second limit rod 703 drive the core sample to rotate.

[0046] The above-mentioned embodiment only expresses one implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
