Description

Technical Field

[0001] The present invention relates to the technical field of concrete testing, and specifically provides a device for testing the durability of concrete under carbon sequestration. Background Art

[0002] An impermeability tester is a special device used to measure the impermeability performance of concrete, mainly detecting the anti-seepage ability of concrete under the action of water pressure. It is a key tool for evaluating the durability of concrete. During the process of testing concrete under carbon sequestration, an impermeability tester is often used. By applying gradually increasing water pressure to a sealed concrete specimen and observing whether there is water seepage on the surface of the specimen, the impermeability grade of the concrete can be evaluated.

[0003] A Chinese patent with the publication number CN114088929A discloses a device for testing the durability of concrete, which includes a durability tester and a test box. The test box is used to form the sample to be tested, and at least one test port is provided thereon; the durability tester is fixedly installed at a position corresponding to one side of the test port above the test box and is used to test the sample. The beneficial effects of the present invention are that the structure is compact, the durability test of concrete can be realized, and the automatic recovery of concrete after testing can be realized without manual collection, saving manpower and having high test efficiency, providing scientific data for engineering construction.

[0004] However, in the actual testing process of concrete blocks, the traditional testing process is as follows: First, a plurality of annular sealing strips are evenly sleeved on the surface of the concrete block, then the concrete block with the sealing strips is sleeved inside the detection cylinder, and finally, an external tool is used to tightly insert the concrete block into the inside of the detection cylinder, and finally the installation between the mounting seat and the detection cylinder is realized. During this process, the sealing strips are prone to displacement due to rubbing, thereby reducing the sealing effect between the concrete block and the detection cylinder.

[0005] Therefore, we propose a device for testing the durability of concrete under carbon sequestration. Summary of the Invention

[0006] The purpose of the present invention is to provide a device for testing the durability of concrete under carbon sequestration to solve the problems raised in the above background art.

[0007] To achieve the above object, the present invention provides the following technical solution: A concrete durability testing device under carbon sequestration, including an impermeability tester and a concrete block.

It further includes: A sealing structure arranged inside the detection cylinder, which is used to improve the tightness when the concrete block is loaded into the detection cylinder for detection; A feeding structure arranged above the impermeability tester, which is used to assist the concrete block to be fed into the detection cylinder.

[0008] The effects achieved by the above components are as follows: By setting the sealing structure, a flexible compressible silica gel ring is arranged in the detection cylinder instead of the traditional structure of directly sleeving a sealing ring on the concrete block. This not only effectively improves the sealing effect on the concrete block and avoids the phenomenon of the traditional sealing strip being rubbed, but also through the flexible compression and expansion of the sealing structure, it is beneficial to the flexible access work of the concrete block inside the detection cylinder, and to a certain extent improves the detection efficiency of the durability of the concrete block.

[0012] The effects achieved by the above components are as follows: The silica gel ring will be affected by the expansion of compressed gas and closely adhere to the side wall of the concrete block, thereby realizing the sealing work between the concrete block and the detection cylinder.

DETAILED DESCRIPTION OF THE INVENTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1-9 , the present invention provides a technical solution: a device for testing the durability of concrete under carbon sequestration, including an impermeability tester 1 and a concrete block 8. A console 2 is fixedly installed on the surface of the impermeability tester 1, and six mounting seats 3 are fixedly installed on the upper surface of the impermeability tester 1. A detection cylinder 4 is fixedly installed on the upper surface of the mounting seat 3. It further includes: a sealing structure 5 arranged inside the detection cylinder 4, and the sealing structure 5 is used to improve the tightness when the concrete block 8 is loaded into the inside of the detection cylinder 4 for detection; a feeding structure 6 arranged above the impermeability tester 1 and used to assist the concrete block 8 to be fed into the inside of the detection cylinder 4. By setting the sealing structure 5, a flexible compressible silica gel ring 504 is arranged in the detection cylinder 4 to replace the traditional structure of directly sleeving a sealing ring on the concrete block 8. This not only effectively improves the sealing effect on the concrete block 8 and avoids the phenomenon of the traditional sealing strip being rubbed, but also through the flexible compression and expansion of the sealing structure 5, it is beneficial to the flexible access work of the concrete block 8 inside the detection cylinder 4, and to a certain extent improves the detection efficiency of the durability of the concrete block 8. By setting the feeding structure 6, it avoids the phenomenon that the fingers are easily pinched during the traditional direct feeding process, and to a certain extent improves the safety of feeding the concrete block 8. A positioning and grinding structure 7 is arranged on the surface of the draw bar 602.

[0034] The following specifically describes the specific settings and functions of its sealing structure 5, feeding structure 6 and positioning and grinding structure 7.

[0035] As Figures 1-6As shown, the sealing structure 5 includes a plurality of reserved grooves 509 formed on the inner side of the detection cylinder 4. The reserved grooves 509 are annular grooves, and a silica gel ring 504 with an annular structure is adhesively bonded to the inner wall of the reserved grooves 509. By providing the reserved grooves 509 with an annular groove structure, the phenomenon that the protruding silica gel ring 504 affects the normal installation of the concrete block 8 is avoided. A plurality of annular holes 510 are formed on the inner side of the detection cylinder 4, a through hole 511 communicating with the reserved grooves 509 is formed between the annular holes 510, an air hole 512 is formed on the upper surface of the detection cylinder 4, and the air hole 512 communicates with the annular holes 510. An inner folding cylinder 502 and an outer folding cylinder 503 are fixedly connected to the upper end side of the detection cylinder 4. The inner folding cylinder 502 is located inside the outer folding cylinder 503, and a pressing ring 501 is fixedly installed at the upper ends of the inner folding cylinder 502 and the outer folding cylinder 503. The silica gel ring 504 is tightly attached to the side wall of the concrete block 8 under the influence of the expansion of the compressed gas, thereby realizing the sealing work between the concrete block 8 and the detection cylinder 4. A first positioning block 505 and a second positioning block 507 are fixedly connected to the side wall of the detection cylinder 4. A sliding rod 506 is slidably connected inside the first positioning block 505, and the upper end of the sliding rod 506 is fixedly connected to the pressing ring 501. A driving rod 508 is threadedly connected inside the second positioning block 507, and the driving rod 508 is rotatably connected to the inside of the pressing ring 501. By rotating the driving rod 508, the driving rod 508 drives the pressing ring 501 to press down. The sliding rod 506 slides inside the first positioning block 505, which plays a role in restricting the moving direction of the pressing ring 501. The pressing ring 501 drives the inner folding cylinder 502 and the outer folding cylinder 503 to press down. At this time, the compression work of the gas between the inner folding cylinder 502, the outer folding cylinder 503 and the pressing ring 501 can be realized.

[0036] As Figures 1-2 and Figures 7-9As shown, the blanking structure 6 includes a guide rail frame 601 fixedly connected to the upper surface of the impermeability tester 1. A rectangular block 609 is slidably connected to the side wall of the guide rail frame 601. A draw bar 602 is slidably connected inside the rectangular block 609. A rectangular frame 603 is fixedly connected to the end side of the draw bar 602. A chute 604 is provided on the side of the rectangular frame 603 away from the draw bar 602. Two sliding plates 605 are slidably connected to the inner wall of the chute 604. At the same time, drive the two sliding plates 605 to move away from each other until the two sliding plates 605 are moved out from under the concrete block 8, and then the concrete block 8 will fall into the inside of the test cylinder 4, thus realizing the blanking work for the test cylinder 4. A spring 606 is fixedly connected between the inner sides of the sliding plate 605 and the rectangular frame 603. After the concrete block 8 falls, release the drive plate 608, and the sliding plate 605 will be reset under the elastic force of the spring 606. Two moving bars 607 are slidably connected inside the rectangular frame 603. A drive plate 608 is fixedly connected between the two moving bars 607. The side of the drive plate 608 close to the rectangular frame 603 is an isosceles triangular plate structure. The inclined surface of the drive plate 608 with an isosceles triangular plate structure will drive the two sliding plates 605 to move away from each other at the same time. Four first jacks 611 are evenly provided on the upper side of the guide rail frame 601. A first plug rod 610 is slidably connected inside the rectangular block 609. The size of the first plug rod 610 is adapted to the size of the first jack 611. An installation plate 612 is fixedly connected to the surface of the rectangular block 609. A second plug rod 613 is slidably connected inside the installation plate 612. Two second jacks 614 are provided on the surface of the draw bar 602. The size of the second plug rod 613 is adapted to the size of the second jack 614. Insert the first plug rod 610 into the inside of the first jack 611 and the second plug rod 613 into the inside of the second jack 614 respectively, and the fixation work for the moved rectangular frame 603 can be realized.

[0037] As Figures 1-2 and Figure 7 as well as Figure 8As shown in the figure, the positioning and grinding structure 7 includes a connecting bar 704 of an L-shaped structure fixedly connected to the upper surface of the draw bar 602. The other end of the connecting bar 704 is fixedly connected with an installation ring 707. The inner side of the installation ring 707 is fixedly installed with a motor 708. The output end of the motor 708 is fixedly connected with a rotating shaft 712. The lower end of the rotating shaft 712 is fixedly connected with a rectangular bar 713. Two limiting grooves 714 are formed on the surface of the rectangular bar 713. The inner walls of the two limiting grooves 714 are both slidably connected with moving blocks 715. The lower end of the moving block 715 is fixedly connected with a positioning bar 705. The cross-section of the positioning bar 705 is V-shaped. The inner side of the positioning bar 705 is glued with a sandpaper 706. The upper surface of the rectangular bar 713 is fixedly connected with a limiting pin 711. The side wall of the limiting pin 711 is slidably connected with a driving frame 709. The driving frame 709 is spliced by two inclined plates and a circular ring. The driving frame 709 is located outside the motor 708. A screw rod 710 is threadedly connected inside the driving frame 709. The screw rod 710 is rotatably connected with the inside of the rectangular bar 713. By setting the positioning and grinding structure 7 to position and grind the concrete block 8, it not only facilitates the subsequent sealing work of the concrete block 8, but also after positioning the concrete block 8, it is more beneficial to accurately fall into the detection cylinder 4 for blanking, further improving the service performance of the durability testing device. A collecting hopper 701 is fixedly connected to the side wall of the impermeability tester 1. The lower port of the collecting hopper 701 is fixedly installed with a threaded ring port 702. The outside of the threaded ring port 702 is threadedly connected with a collecting tank 703. The waste generated during grinding will fall into the inside of the collecting hopper 701 and finally fall into the inside of the collecting tank 703 along the threaded ring port 702 of the collecting hopper 701, realizing the recycling work of the concrete waste.

[0038] Working principle: After placing the concrete block 8 inside the detection cylinder 4, rotate the driving rod 508. The driving rod 508 will drive the pressing ring 501 to press downwards. Among them, the sliding rod 506 slides inside the first positioning block 505, which plays a role in restricting the moving direction of the pressing ring 501. The pressing ring 501 will drive the inner folding cylinder 502 and the outer folding cylinder 503 to press downwards. At this time, the compression of the gas between the inner folding cylinder 502, the outer folding cylinder 503 and the pressing ring 501 can be realized. The compressed gas will flow into the annular hole 510 through the air hole 512. The gas inside the annular hole 510 will finally flow out along the through hole 511, so that the blowing and expanding work of the silica gel pad can be realized. By setting the reserved groove 509 with an annular groove structure, the phenomenon that the protruding silica gel ring 504 affects the normal installation of the concrete block 8 is avoided. The silica gel ring 504 will be closely attached to the side wall of the concrete block 8 under the influence of the expansion of the compressed gas, thus realizing the sealing work between the concrete block 8 and the detection cylinder 4, improving the subsequent detection efficiency of the impermeability of the concrete block 8. Rotating the driving rod 508 in the reverse direction can facilitate the subsequent removal of the concrete block 8 from the inside of the detection cylinder 4. By setting the sealing structure 5, a silica gel ring 504 that can be flexibly compressed is set on the detection cylinder 4 to replace the traditional structure of directly sleeving a sealing ring on the concrete block 8. This not only effectively improves the sealing effect on the concrete block 8 and avoids the phenomenon of the traditional sealing strip being rubbed, but also through the flexible compression and expansion of the sealing structure 5, it is beneficial to the flexible access work of the concrete block 8 inside the detection cylinder 4, and to a certain extent improves the detection efficiency of the durability of the concrete block 8.

[0039] When it is necessary to feed the concrete block 8, the traditional feeding method is to hold the concrete block 8 by hand and insert it into the inner side of the detection cylinder 4 for feeding. Since the weight of the concrete block 8 is relatively large, the fingers are prone to being pinched during this process. When it is necessary to feed the concrete block 8, first place the concrete block 8 above the two sliding plates 605. The movement of the position of the rectangular frame 603 can be realized through the rectangular block 609 on the side wall of the sliding guide frame 601 and the draw bar 602 inside the rectangular block 609. After the concrete block 8 moves to the position above the detection cylinder 4 where it needs to be inserted, insert the first insertion rod 610 into the inner side of the first insertion hole 611 and the second insertion rod 613 into the inner side of the second insertion hole 614 respectively, so as to realize the fixation of the rectangular frame 603 after movement, and then realize the determination of the position of the concrete after movement. At this time, hold the driving plate 608 and push the driving plate 608 towards the position close to the rectangular frame 603. The movement strip 607 slides inside the rectangular frame 603, which plays a role in restricting the moving direction of the driving plate 608. During the movement of the driving plate 608, the inclined surface of the driving plate 608 with an isosceles triangular plate structure will simultaneously drive the two sliding plates 605 to move away from each other until the two sliding plates 605 move out from under the concrete block 8, and then the concrete block 8 will fall into the inner side of the detection cylinder 4, thus realizing the feeding work of the detection cylinder 4. Before this work, the staff can first drive a part of the silica gel ring 504 to expand, which can increase the resistance between the concrete block 8 when it falls into the inner side of the detection cylinder 4 and the inner wall of the detection cylinder 4. Multiple silica gel rings 504 can realize the step-by-step deceleration of the falling of the concrete block 8, avoiding the phenomenon that the concrete block 8 falls directly with a large impact force, which is easy to cause damage to the impermeability tester 1, and reducing the phenomenon that the concrete block 8 is easily broken due to being impacted. After the concrete block 8 falls, release the driving plate 608, and the sliding plate 605 will be reset under the elastic force of the spring 606. By setting the feeding structure 6, it avoids the phenomenon that the fingers are easily pinched during the traditional direct feeding process, and improves the safety of feeding the concrete block 8 to a certain extent.

[0040] When grinding the side wall of the concrete block 8 with uneven side walls before inspection, first move the carrying frame to a position above the collecting hopper 701 for fixation. Then, place the concrete block 8 above the two sliding plates 605. Rotate the screw rod 710, and the screw rod 710 will drive the driving frame 709 to slide on the surface of the limit pin 711. At this time, the two inclined plane structures on the driving frame 709 will simultaneously drive the two moving blocks 715 to move towards each other. The two positioning strips 705 will move with the moving blocks 715 until the two sandpapers 706 move to a position where they are in contact with the side wall of the cylindrical concrete block 8. At this time, the positioning of the concrete block 8 can be achieved, which not only facilitates the subsequent grinding of the concrete block 8 but also benefits the subsequent blanking of the concrete block 8. Then, start the motor 708. The motor 708 will drive the rotating shaft 712 to rotate, and thus the driving rotation of the two positioning strips 705 can be achieved. The sandpapers 706 on the positioning strips 705 will have relative movement with the concrete block 8, and thus the grinding of the side wall of the concrete block 8 can be achieved. The grinding waste will fall into the inner side of the collecting hopper 701 and finally fall into the inner side of the collecting tank 703 along the spiral opening 702 of the collecting hopper 701, realizing the recycling of the concrete waste. After grinding, the side wall of the concrete block 8 is often relatively flat, which is more conducive to the sealing inspection of the concrete block 8 and further improves the inspection efficiency of the concrete block 8. By setting the positioning and grinding structure 7 to position and grind the concrete block 8, it not only facilitates the subsequent sealing of the concrete block 8 but also, after positioning the concrete block 8, is more beneficial for it to accurately fall into the inspection cylinder 4 for blanking, further improving the performance of the durability testing device.
