Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] Refer to Figure 1 、 Figure 3 、 Figure 4, An embodiment provided by the present utility model: A reservoir rock permeability detection device, including a main body 1, the main body 1 is a reservoir rock permeability measuring instrument, a support platform for providing support is arranged at the bottom end of the front surface of the main body 1, a support disk 4 for providing support is arranged on the inner wall of the top end of the support platform, a support rod 3 for providing support is arranged at the top end of the support disk 4, a support plate 2 for providing support and fixation is arranged at the top end of the support rod 3, a fixing component is arranged on the front surface of the support plate 2, the fixing component includes a clamping block 21 and a connecting ring 22, the upper and lower ends of the rear surface of the connecting ring 22 are fixedly connected with the clamping block 21, and the core holder cylinder can be fixed by the cooperation of the clamping block 21 and the connecting ring 22. The clamping block 21 is fixedly connected to the rear surface of the connecting ring 22. A plurality of clamping grooves 24 are formed on the front surface of the support plate 2, and a plurality of clamping grooves 24 are all formed on the front surface of the support plate 2. The plurality of clamping blocks 21 slide into the plurality of clamping grooves 24 and cooperate with the limiting block 25 to quickly fix and limit the core holder cylinder. The clamping block 21 slides on the inner wall of the clamping groove 24, and a pull rod 23 for driving the limiting block 25 to move is slidably connected to the top end of the support plate 2.
[0031] Refer to Figure 1 , Figure 2 , A cleaning component is arranged on the inner wall of the support platform. The cleaning component includes a scraping plate 102 that can scrape off dust or garbage at the bottom end of the inner wall of the support platform. The scraping plate 102 slides on the bottom end of the inner wall of the support platform. A positioning groove 104 for providing support to the positioning block 101 is formed at the top of the front end of the support platform. A positioning block 101 for supporting the scraping plate 102 is fixedly connected to the front surface of the scraping plate 102.
[0032] Refer to Figure 1 , Figure 3 , Figure 4 , A limiting block 25 that can slide into the limiting groove 26 to limit the clamping block 21 is fixedly connected to the bottom end of the pull rod 23. The bottom end of the front surface of the limiting block 25 is set as an inclined surface, and the rear surface of the clamping block 21 is set as an inclined surface. By setting the bottom end of the front surface of the limiting block 25 as an inclined surface and the rear surface of the clamping block 21 as an inclined surface, the inclined surface of the rear surface of the clamping block 21 can be made to squeeze the inclined surface of the bottom end of the front surface of the limiting block 25, causing the limiting block 25 to move upward and compress the spring 27. Thus, it is convenient for the clamping block 21 to slide into the clamping groove 24, and the reverse acting force of the compressed spring 27 drives the limiting block 25 to reset and slide into the limiting groove 26. Therefore, the clamping block 21, the connecting ring 22 and the core holder cylinder can be quickly fixed and limited, improving the convenience of operation. The clamping block 21 and the connecting ring 22 are both provided with two groups, and the two groups of clamping blocks 21 and connecting rings 22 are symmetrically arranged with the center line of the support plate 2 as the axis of symmetry. By setting two groups, the stability of fixing the core holder cylinder is increased.
[0033] Refer to Figure 1 , Figure 3 , Figure 4, a limiting groove 26 for limiting the clamping block 21 in cooperation with the limiting block 25 is provided at the top of the clamping block 21. The limiting block 25 slides on the inner wall of the limiting groove 26. The limiting block 25 is elastically connected to the support plate 2 by a spring 27. One end of the spring 27 is fixedly connected to the top of the limiting block 25, and the other end of the spring 27 is fixedly connected to the inner wall of the support plate 2.
[0034] Refer to Figure 1 , Figure 2 , a chute 105 for placing the collection shell 106 is provided on the right inner wall of the support platform. The collection shell 106 for collecting scraped garbage or dust is inserted into the inner wall of the chute 105. Moving the collection shell 106 upward can quickly remove the collection shell 106, so that it can be quickly cleaned, improving the cleaning efficiency, enhancing the applicability and convenience of the equipment. The positioning block 101 is slidably connected to the inner wall of the positioning groove 104. A guide rod 103 that can drive the scraping plate 102 to move to scrape dust or garbage into the right collection shell 106 is fixedly connected to the top of the positioning block 101.
[0035] Working principle: When in use, after placing the core in the core holder cylinder, the core holder cylinder can be placed at the inner walls of the clamping block 21 and the connecting ring 22 at this time. Then, after aligning the clamping block 21 with the card slot 24 by moving the clamping block 21, the clamping block 21 is slid into the card slot 24. Since the rear surface of the clamping block 21 is set as an inclined surface, the inclined surface of the clamping block 21 squeezes the inclined surface at the bottom of the front surface of the limiting block 25, so that the limiting block 25 can move upward to squeeze the spring 27. When the clamping block 21 slides into the card slot 24 and contacts the inner wall of the rear surface of the card slot 24, the limiting groove 26 and the limiting block 25 can be aligned at this time. Then, the reverse acting force of the spring 27 being squeezed can drive the limiting block 25 to reset, so that the limiting block 25 slides into the limiting groove 26, quickly limiting the clamping block 21 and the connecting ring 22. By setting two groups of clamping blocks 21 and connecting rings 22, the stability of fixing the core holder cylinder can be increased, quickly limiting the core holder cylinder, improving the convenience of operation and the detection efficiency at the same time.
[0036] After the detection is completed, the support plate 4 is moved out of the support platform at this time. Then, by moving the guide rod 103, the positioning block 101 and the scraping plate 102 are driven to move. The scraping plate 102 moves and contacts the bottom end of the inner wall of the support platform, so that the dust or garbage at the bottom end of the inner wall of the support platform can be scraped off. By scraping the dust or garbage into the right collection shell 106, the collection shell 106 can be directly removed for cleaning, so as to achieve the effect of quick cleaning, improving the cleaning efficiency and enhancing the applicability and convenience of the equipment.
[0037] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
