Description

Technical Field

[0001] The present invention relates to the technical field of concrete impermeability, and specifically relates to a concrete impermeability tester for engineering detection. Background Technique

[0002] A concrete impermeability tester is an engineering detection device used to evaluate the impermeability performance of concrete. Through the impermeability test, the safety, applicability, durability or disaster resistance of the concrete structure can be evaluated. This is crucial for ensuring the performance of the engineering structure during long-term use.

[0003] The patent with the publication number CN117129402A discloses a concrete impermeability test device for engineering quality detection, including a detection box body. An osmometer is installed in the detection box body. A specimen mold is fixed to the top of the osmometer by bolts. A shallow tray is provided on the top of the detection box body. A driving component is provided on the shallow tray. A roller brush is rotatably connected in the shallow tray. A transmission component is provided on the shallow tray and the roller brush. A connecting rod is rotatably connected to the top of the shallow tray. A brush base is slidably connected to the connecting rod. A soft brush is slidably arranged on the brush base. In this patent, a driving motor drives the clamping member II and the clamping member I to drive the concrete specimen to rotate, so that the side surface of the concrete specimen rolls in the paraffin melt for two weeks. The paraffin on the concrete specimen is further evenly smeared by the forward and backward movement of the soft brush, so that the side surface of the concrete specimen is sealed.

[0004] However, the above device does not test the concrete under a vacuum state during detection, resulting in different detection results under different air pressure states, thereby affecting the detection accuracy of the device. Therefore, a concrete impermeability tester for engineering detection is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a concrete impermeability tester for engineering detection in view of the deficiencies in the above-mentioned prior art.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is as follows: A concrete impermeability tester for engineering inspection, comprising a box body and a closing plate. A water tank is fixedly connected to the top of the box body. A water pump is fixedly installed on the top of the water tank, and a vacuum device is fixedly installed on the top of the water tank. The water outlet end of the water pump is fixedly communicated with a water pipe, and the air suction end of the vacuum device is fixedly communicated with an air extraction pipe. A fixed platform is fixedly connected to the top of the box body. A fixing mechanism is arranged on the top of the box body. A scraping mechanism is arranged inside the box body. An extrusion mechanism is arranged inside the box body. A motor is installed inside the box body. A fixing rod is fixedly connected to the top of the fixed platform, and a cylinder is installed on the top of the fixing rod. The fixing mechanism includes a transmission rod, a fixed round block, a long scraping rod, bristles, a connecting rod, a compression disc, a compression cylinder, a long block, a first telescopic rod, a clamping block, and a water outlet round plate. The transmission rod is fixedly connected to the output end of the cylinder. The fixed round block is fixedly connected to the circumferential surface of the transmission rod. The long scraping rod is fixedly connected to the circumferential surface of the fixed round block. The bristles are fixedly connected to the arc surface of the long scraping rod.

The compression cylinder is fixedly connected to the top of the box body. The long block is fixedly connected to the inner wall of the compression cylinder. The first telescopic rod is fixedly connected to the surface of the long block. The clamping block is fixedly connected to the side of the first telescopic rod away from the long block. The water outlet round plate is fixedly connected to the inner bottom wall of the compression cylinder. A weighing component is arranged on the inner wall of the closing plate. The end of the water pipe away from the water pump is fixed to the top of the compression disc. The compression disc is in contact with the inner wall of the compression cylinder, so as to extrude the concrete sample and make the concrete sample remain stationary on the top of the compression disc without moving. At the same time, there will be a partition coating between the water outlet round plate and the concrete sample to ensure that when water enters, the water cannot flow out through the gaps other than the inside of the concrete, thus affecting the accuracy of the detection and improving the use precision of the device. The vacuum device is started to suck out the air inside the compression cylinder through the air extraction pipe, so that the inside of the compression cylinder is in a vacuum state, thereby ensuring the accuracy of the test results and reducing the presence of residues or dirt in the tester, which may affect the distribution of water pressure and lead to inaccurate test results.

[0007] Preferably, the scraping mechanism includes a conical funnel, a first connecting column, an inner disc, and an electric percussion rod. The first connecting column is fixedly connected to the top of the inner wall of the box body. The conical funnel is fixedly connected to the bottom of the first connecting column away from the compression cylinder. The inner disc is fixedly connected to the bottom of the connecting rod. The electric percussion rod is fixedly connected to the inner wall of the inner disc. The scraping mechanism further includes an inner water device, a three-week plate, and a cleaning rod. The inner water device is rotatably connected to the inner surface of the conical funnel. The three-week plate is movably connected to the circumferential surface of the connecting rod. The cleaning rod is fixedly connected to the top of the inner water device. A non-self-locking spiral groove is formed on the circumferential surface of the connecting rod. A clamping rod is provided on the inner wall of the three-week plate and is located in the non-self-locking spiral groove. The cleaning rod is in sliding contact with the inner surface of the conical funnel. The output end of the electric percussion rod is in contact with the surface of the conical funnel. The number of cleaning rods is multiple, and the multiple cleaning rods are circularly and neatly distributed on the top of the inner water device. The top of the three-week plate is rotatably connected to the top of the inner wall of the box body, so that the water on the surface of the conical funnel can drip into the round sponge at the bottom through the opening of the inner water device, ensuring that all the flowing water can be detected when detecting the volume and weight of the water, further ensuring the detection accuracy of the device, improving the use efficiency of the equipment, thus ensuring the accuracy of the test results, and reducing the presence of residues or dirt in the tester, which may affect the water pressure distribution and lead to inaccurate test results.

[0008] Preferably, the extrusion mechanism includes a second connecting column, a rotating block, a rotating rod, an L-shaped plate, a second telescopic rod, and an extrusion plate. The second connecting column is fixedly connected to the output end of the motor. The rotating block is fixedly connected to the circumferential surface of the second connecting column. The rotating rod is fixedly connected to the circumferential surface of the rotating block. The L-shaped plate is fixedly connected to the top of the rotating rod. The second telescopic rod is fixedly connected to the surface of the L-shaped plate. The extrusion plate is fixedly connected to the bottom of the second telescopic rod. The extrusion mechanism further includes a round sponge and a convex block. The closing plate is rotatably connected to the top of the second connecting column. The round sponge is fixedly connected to the top surface of the closing plate. The convex block is fixedly connected to the bottom of the extrusion plate. The top of the connecting rod is in contact with the bottom of the fixed platform. The surface of the convex block is in contact with the top surface of the round sponge. The extrusion plate is in sliding contact with the inner wall of the closing plate, so that the round sponge will absorb the dripping water, reducing the splashing of the leaking water outside the detection platform while dripping, reducing the amount of water in the detection experiment, which may lead to inaccurate results in subsequent detections. The extrusion plate will contact the round sponge and squeeze the round sponge through the convex block at the bottom of the extrusion plate, so that the water in the round sponge can be evenly distributed after being squeezed, making the weight of the water-absorbed round sponge evenly distributed and improving the accuracy of weighing measurement.

[0009] Adopting the above technical solutions, the present invention can bring the following beneficial effects:

[0010] 1. The concrete impermeability tester for engineering detection, through the mutual cooperation and movement among the transmission rod, fixed round block, long scraping rod, brush hair, connecting rod, compression disc, compression cylinder, long square block, first telescopic rod, clamping block, and water outlet round plate, the device will squeeze the concrete sample to keep the concrete sample stationary on the top of the compression disc without moving. At the same time, there will be a partition coating between the water outlet round plate and the concrete sample to ensure that when water enters, the water cannot flow out through the gaps other than inside the concrete, thus affecting the accuracy of the detection, improving the use precision of the device. At the same time, the vacuum device is started to suck out the air inside the compression cylinder through the air extraction pipe, making the inside of the compression cylinder in a vacuum state, thereby ensuring the accuracy of the test results, reducing the presence of residues or dirt in the tester that may affect the water pressure distribution and cause inaccurate test results.

[0011] 2. The concrete impermeability tester for engineering detection, through the mutual cooperation and movement among the conical leak, first connecting column, inner disc, electric knocking rod, inner water device, three-week plate, and cleaning rod, enables the water on the surface of the conical leak to drip into the bottom round sponge through the opening of the inner water device, ensuring that all the flowing water can be detected when measuring the volume and weight of the water, further guaranteeing the detection accuracy of the device and improving the use efficiency of the equipment. The knocking of the conical leak can vibrate and drop some residual water stains on the inner surface of the conical leak, cleaning the inner water stains of the conical leak, ensuring that in the next concrete detection, it will not affect the detection effect and making the continuous detection effect of the equipment more accurate and precise.

[0012] 3. The concrete impermeability tester for engineering detection, through the mutual cooperation and movement among the second connecting column, rotating block, rotating rod, L-shaped plate, second telescopic rod, extrusion plate, closing plate, round sponge, and convex block, enables the round sponge to absorb the dripping water, reducing the splashing of the leaked water outside the detection platform while dripping, reducing the amount of water in the detection experiment, which may lead to inaccurate results in subsequent detections. The extrusion plate will contact the round sponge and squeeze the round sponge through the convex block at the bottom of the extrusion plate, so that the water in the round sponge can be evenly distributed after being squeezed, making the weight of the water-absorbed round sponge evenly distributed and improving the accuracy of weighing measurement.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 - 8, an embodiment of the present invention is: a concrete impermeability tester for engineering detection, including a box body 1 and a closing plate 807. A water tank 4 is fixedly connected to the top of the box body 1. A water pump 2 is fixedly installed on the top of the water tank 4. A vacuum device 3 is fixedly installed on the top of the water tank 4. The water outlet end of the water pump 2 is fixedly communicated with a water pipe 11. The suction end of the vacuum device 3 is fixedly communicated with an air extraction pipe 10. A fixing platform 13 is fixedly connected to the top of the box body 1. A fixing mechanism 6 is arranged on the top of the box body 1. A scraping mechanism 7 is arranged inside the box body 1. An extrusion mechanism 8 is arranged inside the box body 1. A motor 9 is installed inside the box body 1. A fixing rod 12 is fixedly connected to the top of the fixing platform 13. A cylinder 5 is installed on the top of the fixing rod 12. The fixing mechanism 6 includes a transmission rod 601, a fixing round block 602, a long scraping rod 603, bristles 604, a connecting rod 605, a compression disc 606, a compression cylinder 607, a long block 608, a first telescopic rod 609, a clamping block 610, and a water outlet round plate 611. The transmission rod 601 is fixedly connected to the output end of the cylinder 5. The fixing round block 602 is fixedly connected to the circumferential surface of the transmission rod 601. The long scraping rod 603 is fixedly connected to the circumferential surface of the fixing round block 602. The bristles 604 are fixedly connected to the arc surface of the long scraping rod 603. The connecting rod 605 is fixedly connected to the circumferential surface of the fixing round block 602. The compression disc 606 is fixedly connected to the side of the transmission rod 601 away from the cylinder 5. The compression cylinder 607 is fixedly connected to the top of the box body 1. The long block 608 is fixedly connected to the inner wall of the compression cylinder 607. The first telescopic rod 609 is fixedly connected to the surface of the long block 608. The clamping block 610 is fixedly connected to the side of the first telescopic rod 609 away from the long block 608. The water outlet round plate 611 is fixedly connected to the inner bottom wall of the compression cylinder 607. A weighing assembly is arranged on the inner wall of the closing plate 807. The end of the water pipe 11 away from the water pump 2 is fixedly connected to the top of the compression disc 606. The compression disc 606 is in contact with the inner wall of the compression cylinder 607. Before the device is started, an operator puts the concrete sample to be detected into the compression cylinder 607. At the same time, the cylinder 5 starts to operate. The output end of the cylinder 5 will push the transmission rod 601. The movement of the transmission rod 601 drives the compression disc 606 to move downward, pushing and extruding the concrete sample, so that the concrete sample passes through the arc on the clamping block 610, squeezing and pushing the first telescopic rod 609. The first telescopic rod 609 drives the long block 608 to be compressed. When the bottom of the concrete sample is completely in contact with the water outlet round plate 611 inside the compression cylinder 607, the first telescopic rod 609 will reset, squeezing the concrete sample so that the concrete sample remains stationary on the top of the compression disc 606 and cannot move. At the same time, there will be a partition coating between the water outlet round plate 611 and the concrete sample, ensuring that when water enters, the water cannot flow out through the gaps other than inside the concrete, thus affecting the accuracy of the detection and improving the use precision of the device. After the concrete is fixed, the cylinder 5 will drive the transmission rod 601 to move upward. The transmission rod 601 drives the fixing round block 602 to move. The fixing round block 602 drives the long scraping rod 603 to move. The long scraping rod 603 drives the bristles 604 to move. During the rising process of the bristles 604,The bristles 604 will come into contact with the surface of the compression cylinder 607, scraping off the sundries and dust contaminated when the concrete sample is placed on the inner wall of the compression cylinder 607. At this time, the water pump 2 will start, and the water in the water tank 4 will be discharged into the compression cylinder 607 through the water pipe 11. At the same time, the vacuum device 3 starts to suck out the air inside the compression cylinder 607 through the suction pipe 10, making the inside of the compression cylinder 607 in a vacuum state, further improving the effect of concrete testing, ensuring that the test process is not interfered by external pollutants, thus ensuring the accuracy of the test results, reducing the presence of residues or dirt in the tester, which may affect the water pressure distribution and lead to inaccurate test results.

[0024] The scraping mechanism 7 includes a conical funnel 701, a first connecting column 702, an inner disc 703, and an electric percussion rod 704. The first connecting column 702 is fixedly connected to the top of the inner wall of the box body 1. The conical funnel 701 is fixedly connected to the bottom of the first connecting column 702 away from the compression cylinder 607. The inner disc 703 is fixedly connected to the bottom of the connecting rod 605. The electric percussion rod 704 is fixedly connected to the inner wall of the inner disc 703. The scraping mechanism 7 further includes an inner water device 705, a three-week plate 706, and a cleaning rod 707. The inner water device 705 is rotatably connected to the inner surface of the conical funnel 701. The three-week plate 706 is movably connected to the circumferential surface of the connecting rod 605. The cleaning rod 707 is fixedly connected to the top of the inner water device 705. A non-self-locking spiral groove is provided on the circumferential surface of the connecting rod 605. A clamping rod is provided on the inner wall of the three-week plate 706, and the clamping rod is located in the non-self-locking spiral groove. The cleaning rod 707 is in sliding contact with the inner surface of the conical funnel 701. Through the water flowing out from the bottom of the concrete sample, the water will pass through the water outlet circular plate 611 and enter the inside of the conical funnel 701, flow along the surface of the conical funnel 701 into the measuring device at the bottom. At the same time, the transmission rod 601 moves to drive the connecting rod 605 to move downward. During the movement, the three-week plate 706 will rotate through the non-self-locking spiral groove on the connecting rod 605. The rotation of the three-week plate 706 will contact and push the cleaning rod 707 to rotate, so that the cleaning rod 707 rotates and moves on the inner surface of the conical funnel 701 with the inner water device 705 as the center. At this time, during the rotation and movement of the cleaning rod 707, the cleaning rod 707 will scrape off the water on the inner wall surface of the conical funnel 701, so that the water on the surface of the conical funnel 701 can drip into the circular sponge 808 at the bottom through the opening of the inner water device 705, ensuring that all the flowing water can be detected when detecting the volume and weight of the water, further ensuring the detection accuracy of the device, improving the use efficiency of the equipment. The output end of the electric percussion rod 704 is in contact with the surface of the conical funnel 701. The number of the cleaning rods 707 is set to be multiple, and the multiple cleaning rods 707 are circularly and integrally distributed on the top of the inner water device 705. The top of the three-week plate 706 is rotatably connected to the top of the inner wall of the box body 1. At the same time, after the connecting rod 605 moves a certain distance, the inner disc 703 will cover the conical funnel 701, and the electric percussion rod 704 on the inner wall of the inner disc 703 will strike the surface of the conical funnel 701. The percussion of the conical funnel 701 can vibrate and drop some residual water stains on the inner surface of the conical funnel 701, cleaning the inner water stains of the conical funnel 701, ensuring that in the next concrete detection, it will not affect the detection effect, and making the continuous detection effect of the device more accurate and precise.

[0025] Working principle: Before the device starts, manually place the concrete sample to be tested inside the compression cylinder 607. At the same time, the air cylinder 5 starts. The output end of the air cylinder 5 will push the transmission rod 601. The movement of the transmission rod 601 drives the compression disc 606 to move downward, pushing and extruding the concrete sample, causing the concrete sample to pass through the arc on the clamping block 610, squeezing and pushing the first telescopic rod 609. The first telescopic rod 609 drives the rectangular block 608 to compress. When the bottom of the concrete sample completely contacts the water outlet circular plate 611 inside the compression cylinder 607, the first telescopic rod 609 will reset, squeezing the concrete sample to keep the concrete sample stationary on the top of the compression disc 606 and unable to move. At the same time, there will be a partition coating between the water outlet circular plate 611 and the concrete sample to ensure that when water enters, the water cannot flow out through the gaps other than inside the concrete, thus affecting the test accuracy and improving the use precision of the device. After the concrete is fixed, the air cylinder 5 will drive the transmission rod 601 to move upward. The transmission rod 601 drives the fixed circular block 602 to move. The fixed circular block 602 drives the long scraping rod 603 to move. The long scraping rod 603 drives the brush bristles 604 to move. During the upward movement of the brush bristles 604, the brush bristles 604 will contact the surface of the compression cylinder 607 and scrape off the sundries and dust contaminated when the concrete sample was placed on the inner wall of the compression cylinder 607. At this time, the water pump 2 will start and discharge the water in the water tank 4 into the compression cylinder 607 through the water pipe 11. At the same time, the vacuum device 3 starts and sucks out the air inside the compression cylinder 607 through the suction pipe 10, making the inside of the compression cylinder 607 in a vacuum state, further improving the effect of the concrete test, ensuring that the test process is not interfered by external pollutants, thus ensuring the accuracy of the test results, and reducing the possibility that residues or dirt in the tester may affect the water pressure distribution and lead to inaccurate test results.

[0026] Through the water flowing out from the bottom of the concrete sample, the water will pass through the water outlet circular plate 611 and enter the inside of the conical funnel 701. Then it will flow along the surface of the conical funnel 701 into the measuring device at the bottom. At the same time, the transmission rod 601 moves to drive the connecting rod 605 to move downward. During the movement, the three-week plate 706 will rotate through the non-self-locking spiral groove on the connecting rod 605. The rotation of the three-week plate 706 will contact the cleaning rod 707 and push it to rotate, causing the cleaning rod 707 to rotate and move on the inner surface of the conical funnel 701 with the inner water device 705 as the center. At this time, during the rotation and movement of the cleaning rod 707, the cleaning rod 707 will scrape off the water on the inner wall surface of the conical funnel 701, so that the water on the surface of the conical funnel 701 can drip into the circular sponge 808 at the bottom through the opening of the inner water device 705, ensuring that all the flowing water can be detected when detecting the volume and weight of the water, further guaranteeing the detection accuracy of the device, improving the use efficiency of the equipment. At the same time, after the connecting rod 605 moves a certain distance, the inner disc 703 will cover the conical funnel 701, and the electric hammer 704 on the inner wall of the inner disc 703 will strike the surface of the conical funnel 701. The striking of the conical funnel 701 can vibrate and drop some residual water stains on the inner surface of the conical funnel 701, cleaning the inner water stains of the conical funnel 701, ensuring that in the next concrete detection, the detection effect will not be affected, and making the continuous detection effect of the equipment more accurate and precise.

[0027] Please refer to Figures 1 - 8, on the basis of the above embodiments, in another embodiment of the present invention, the extrusion mechanism 8 includes a second connecting column 801, a rotating block 802, a rotating rod 803, an L-shaped plate 804, a second telescopic rod 805, and an extrusion plate 806. The second connecting column 801 is fixedly connected to the output end of the motor 9. The rotating block 802 is fixedly connected to the circumferential surface of the second connecting column 801. The rotating rod 803 is fixedly connected to the circumferential surface of the rotating block 802. The L-shaped plate 804 is fixedly connected to the top of the rotating rod 803. The second telescopic rod 805 is fixedly connected to the surface of the L-shaped plate 804. The extrusion plate 806 is fixedly connected to the bottom of the second telescopic rod 805. The extrusion mechanism 8 further includes a round sponge 808 and a convex block 809. The closing plate 807 is rotatably connected to the top of the second connecting column 801. The round sponge 808 is fixedly connected to the top surface of the closing plate 807. At the same time, the leaked water flows down through the conical leak 701 and drips at the opening of the inner water device 705 onto the round sponge 808 on the top of the closing plate 807. The round sponge 808 will absorb the dripping water, reducing the splashing of the leaked water outside the detection platform while dripping, reducing the amount of water in the detection experiment, which may cause inaccurate results in subsequent detections and further affect the detection effect of the device. The convex block 809 is fixedly connected to the bottom of the extrusion plate 806. The top of the connecting rod 605 contacts the bottom of the fixed table 13. The surface of the convex block 809 contacts the top surface of the round sponge 808. The extrusion plate 806 is in sliding contact with the inner wall of the closing plate 807. At the same time, after the leaked water drops onto the surface of the round sponge 808, the motor 9 will be started. The output end of the motor 9 will drive the second connecting column 801 to rotate. The rotation of the second connecting column 801 drives the rotating block 802 to rotate. The rotation of the rotating block 802 will drive the L-shaped plate 804 above it to rotate. At this time, the rotation of the L-shaped plate 804 will drive the second telescopic rod 805 to rotate. The rotation of the second telescopic rod 805 will drive the extrusion plate 806 to rotate. While the extrusion plate 806 rotates, the extrusion plate 806 will contact the round sponge 808 and squeeze the round sponge 808 through the convex block 809 at the bottom of the extrusion plate 806, so that the water in the round sponge 808 can be evenly distributed after being squeezed, making the weight of the round sponge 808 evenly distributed after absorbing water and improving the accuracy of weighing measurement.

[0028] Working principle: The water leaking simultaneously flows down through the conical leak 701 and drips onto the round sponge 808 on the top of the closing plate 807 at the opening of the inner water device 705. The round sponge 808 will absorb the dripping water, reducing the splashing of the leaking water outside the detection platform while dripping, reducing the amount of water for the detection experiment, which may lead to inaccurate results in subsequent detections and further affect the detection effect of the device. At the same time, after the leaking water drops onto the surface of the round sponge 808, the motor 9 will start. The output end of the motor 9 will drive the second connecting column 801 to rotate. The rotation of the second connecting column 801 drives the rotating block 802 to rotate. The rotation of the rotating block 802 will drive the L-shaped plate 804 on itself to rotate. At this time, the rotation of the L-shaped plate 804 will drive the second telescopic rod 805 to rotate. The rotation of the second telescopic rod 805 will drive the pressing plate 806 to rotate. While the pressing plate 806 is rotating, the pressing plate 806 will contact the round sponge 808 and squeeze the round sponge 808 through the convex block 809 at the bottom of the pressing plate 806, so that the water in the round sponge 808 can be evenly distributed after being squeezed, making the weight of the round sponge 808 after absorbing water evenly distributed and improving the accuracy of weighing measurement.

The above description is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be implemented by using the prior art.
