Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a mud scraping device for a sampling tube of a deep-sea sediment sampler. Background Technology

[0002] In many industries, sampling tubes are used to obtain samples during testing. For example, in the field of oil exploration, core samples extracted from wells are transported to the laboratory for analysis using sampling tubes; in the field of environmental monitoring, samples obtained from water or soil are also collected using sampling tubes. These samples are crucial for research and decision-making. However, after the samples are taken out, dirt tends to adhere to the tube wall, making it difficult to remove. Traditional simple wiping or rinsing methods are insufficient to effectively remove dirt from the outer wall of the sampling tube, affecting subsequent sampling operations. Utility Model Content

[0003] The main purpose of this utility model is to solve the above-mentioned technical problems to a certain extent, and to propose a mud scraping device for the sampling tube of a deep-sea sediment sampler, which can effectively remove mud and dirt from the outer wall of the sampling tube and ensure the subsequent sampling work of the sampling tube.

[0004] This application provides a mud scraping device for a deep-sea sediment sampler, including a base plate, a sampling seat, a hook fixing seat, a mud scraping sleeve, and a clamping assembly. The base plate has a support column, and a support seat is fixed on the support column. The sampling seat is located on one side of the support seat, and the sampling tube is placed inside the sampling seat, with its handle exposed on the outside of the sampling seat. The hook fixing seat is located on the other side of the support seat. The mud scraping sleeve is located on the hook fixing seat. A scraping groove extends through the mud scraping sleeve along its height. A mud guiding slope matching the outer contour of the sampling tube is located inside the mud scraping sleeve and above the scraping groove. A sealing groove is located near the bottom of the mud guiding slope in the scraping groove, and a sealing ring is located within the sealing groove. An installation groove is located below the sealing groove, and a scraper is located within the installation groove. The part of the scraper extending out of the installation groove scrapes away mud from the outer wall of the pulled-out sampling tube. The clamping assembly is located on the hook fixing seat and abuts against the outer wall of the mud scraping sleeve.

[0005] In some embodiments, the claw fixing seat is provided with at least four sets of claw portions, and each claw portion is provided with a clamping component.

[0006] In some embodiments, the clamping assembly includes a fixed member, a movable member, and a spring. The fixed member is fixed to the hook portion. The movable member is movably disposed on the fixed member in a direction perpendicular to the axis of the scraper sleeve and has a locking pin at its end. The outer surface of the scraper sleeve has a stepped groove facing the position where the locking pin is inserted. The two ends of the spring are respectively connected to the fixed member and the movable member to push the locking pin against the stepped groove.

[0007] In some embodiments, the inner wall of the scraper groove is bonded with felt.

[0008] In some embodiments, the lower end face of the felt is in contact with the sealing ring, and the upper end face of the felt is flush with the mud guide slope.

[0009] In some embodiments, the inner diameter of the scraping groove is the same as the outer diameter of the portion of the sampling tube to be scraped.

[0010] The technical solutions provided in this application have the following advantages compared with the prior art:

[0011] As the sampling tube moves up and down within the scraper sleeve, the scraper inside the sleeve scrapes the outer wall of the sampling tube back and forth, thus removing the mud and dirt from the outer wall of the sampling tube without damaging it, ensuring the smooth operation of subsequent sampling. Furthermore, the guide slope provided by the scraper sleeve facilitates the accumulation of mud and dirt removed from the outer wall of the sampling tube, while the felt further cleans the outer wall of the sampling tube, improving the effectiveness of mud and dirt removal.

[0012] Furthermore, the sampling tube is inserted into the sampling seat to facilitate its removal. The sludge scraper is placed in the hook fixing seat and positioned by the clamping component to ensure the stability of the sludge scraper position when the sampling tube is lifted.

The sampling tube 100 is inserted into the sampling seat 2, and the hand-held portion of the sampling tube 100 is exposed on the outside of the sampling seat 2 for easy handling. An indicator light 8 is provided on the exposed portion of the sampling tube 100. The hook fixing seat 3 is located on the other side of the support seat 7. The scraping sleeve 4 is provided with… A scraping groove is provided inside the hook fixing seat 3 and the scraping sleeve 4 along its height direction. The inner diameter of the scraping groove is the same as the outer diameter of the part of the sampling tube 100 to be scraped. The hook fixing seat 3 and the scraping groove are coaxially provided with a slot larger than the outer diameter of the sampling tube 100. Inside the scraping sleeve 4 and above the scraping groove, there is a mud guiding slope 9 that matches the outer contour of the sampling tube 100. A sealing groove is provided near the bottom of the scraping groove and a sealing ring 10 is provided in the sealing groove. An installation groove is provided below the sealing groove and a scraper 11 is provided in the installation groove. The part of the scraper 11 that extends out of the installation groove scrapes the mud off the outer wall of the pulled-out sampling tube 100. The clamping component 5 is provided on the hook fixing seat 3 and abuts against the outer wall of the scraping sleeve 4.

[0022] In this embodiment, as the sampling tube 100 is pulled up and down within the scraper sleeve 4, the scraper 11 inside the scraper sleeve 4 scrapes the outer wall of the sampling tube 100 back and forth, thereby removing the mud and dirt from the outer wall of the sampling tube 100 without damaging it, ensuring the subsequent sampling work of the sampling tube 100; and the guide slope 9 provided by the scraper sleeve 4 facilitates the accumulation of the mud and dirt removed from the outer wall of the sampling tube 100. The scraper sleeve 4 is placed on the hook fixing seat 3, and the scraper sleeve 4 is positioned by the clamping component 5 to ensure the stability of the position of the scraper sleeve 4 when the sampling tube 100 is pulled up.

[0023] Furthermore, such as Figure 3 As shown, a felt 12 is bonded to the inner wall of the scraper groove. The lower end face of the felt 12 is in contact with the sealing ring 10, and the upper end face of the felt 12 is flush with the mud guide slope 9. The felt 12 and the sealing ring 10 can further clean the outer wall of the sampling tube 100, so as to improve the mud scraping efficiency and prevent the adhesion of sediment.

[0025] Before using the device, place the scraper sleeve 4 on the hook fixing seat 3, and push the four movable parts 502 with the spring 503 so that the locking pins 504 at their ends are inserted into the stepped groove 13 of the scraper sleeve 4, thereby preventing the scraper sleeve 4 from moving upward when the sampling tube 100 is pulled upward; after sampling is completed, place the sampling seat 2 with the sampling tube 100 on the support seat 7, then take the sampling tube 100 out of the sampling seat 2 and align the sampling tube 100 with the scraper sleeve 4. After scraping the groove, the sampling tube 100 is inserted downward into the groove. When the outer contour of the sampling tube 100 coincides with that of the groove, the sampling tube 100 is pulled upward until the entire sampling tube 100 is removed from the sludge sleeve 4. When the sampling tube 100 is inserted and removed back and forth, the scraper 11 will scrape and remove the sludge on the outer wall of the sampling tube 100. The felt 12 and the sealing ring 10 are used to improve the cleaning effect on the outer wall of the sampling tube 100. The sludge falls from the groove and the empty groove into the recycling box below.

[0026] The above description is only a preferred embodiment of the present utility model.
