Description

Technical Field

[0001] This utility model relates to the field of concrete quality testing technology, specifically a concrete quality testing device for water conservancy projects. Background Technology

[0002] In water conservancy projects, concrete is often used extensively in the construction of dams, canals, dikes and other structures. In order to ensure that the quality of concrete meets the design requirements, slump testing is often used in the quality inspection of concrete before it sets in water conservancy projects. The method of slump testing is to inject concrete into a slump bucket in multiple stages, and then manually lift the slump bucket vertically upward to allow the concrete to collapse freely. After the collapse stops, the slump is obtained by subtracting the height of the highest point of the concrete after the collapse from the height of the bucket.

[0003] Chinese patent (authorization announcement number: CN 222125258 U, authorization announcement date: 2024.12.06) proposes a concrete quality testing device for water conservancy projects. This utility model, through the cooperation of a stepper motor, a rotating shaft, and a mounting plate, can exchange the positions of the lifting mechanism and the measuring mechanism. The lifting mechanism and the measuring mechanism can reduce errors caused by human operation. At the same time, with the cooperation of a linear guide module, a scraper, and a cleaning mechanism, the concrete on the inner wall of the cone and the top of the operating platform can be cleaned. This not only saves the labor intensity of the staff but also improves the testing efficiency. It solves the problems of errors in slump detection and poor concrete cleaning efficiency of current testing devices.

[0004] The aforementioned concrete quality testing device for water conservancy projects directly discharges wastewater through the guide shell without recycling, resulting in water waste. Furthermore, the cleaning process, which relies solely on fixed nozzles and rubber rings for friction, is insufficient to remove stubborn residues from the inner wall of the cone, leading to a decrease in subsequent testing accuracy. Therefore, we propose a concrete quality testing device for water conservancy projects. Utility Model Content

At the same time, the second nozzle performs targeted rinsing of the discharge platform to ensure that no concrete residue adheres to the cleaning pool, thus solving the problems mentioned earlier.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a concrete quality testing device for water conservancy projects, including an equipment box 1, a cleaning pool 3 and a material discharge platform 2 respectively provided on the top left and right sides of the equipment box 1, a cleaning component installed on the material discharge platform 2, a circulating cleaning component installed on the cleaning pool 3, and a testing component installed in the middle of the top side of the equipment box 1.

[0022] The concrete quality testing device for this water conservancy project uses the equipment box 1 as the main frame. A cleaning pool 3 is set on the left side of the top, and a feeding platform 2 is set on the right side. During testing, the concrete to be tested is placed on the feeding platform 2, and the slump test is carried out by the testing component. After the test is completed, the cleaning component is activated to remove the residual concrete on the feeding platform 2. At the same time, the circulating cleaning component runs to clean the feeding platform 2 and the testing component in a cyclical manner to ensure thorough cleaning.

[0023] The circulating cleaning assembly includes a water storage tank 13, which is located inside the rear side of the equipment housing 1. A water pump 14 is also fixedly installed inside the bottom side of the equipment housing 1. The input end of the water pump 14 is fixedly connected to the water storage tank 13 through a pipe. The output end of the water pump 14 is fixedly connected to a water outlet pipe 23. The output end of the water outlet pipe 23 is fixedly connected to a solenoid valve 22. A spray pipe 29 is rotatably installed through the bottom of the cleaning tank 3. Several nozzles 30 are installed on the spray pipe 29. A brush plate 32 is fixedly connected to the outer surface of the spray pipe 29. A rotary joint 11 is fixedly connected to the input end of the rotary joint 11 through a pipe. A rotating mechanism and a return mechanism are installed on the bottom side of the cleaning tank 3. A cleaning mechanism is also installed on the rear side of the cleaning tank 3.

[0024] The rotating mechanism includes a drive motor 10, which is fixedly installed on the bottom side of the cleaning tank 3. A bevel gear 34 is fixedly connected to the output shaft end of the drive motor 10. A bevel gear 33 is fixedly sleeved on the bottom outer surface of the spray pipe 29. The bevel gear 33 meshes with the bevel gear 34.

[0025] The return mechanism includes a return water tank 15, which is fixedly connected to the water storage tank 13 via a pipe. A filter frame 16 is installed inside the return water tank 15. A connecting groove 20 is opened on the front side of the bottom of the cleaning tank 3, and a sewage pipe 21 is fixedly connected to the bottom of the connecting groove 20.

[0026] The cleaning mechanism includes a second solenoid valve 24. The input end of the second solenoid valve 24 is fixedly connected to the first water outlet pipe 23 via a pipe. The output end of the second solenoid valve 24 is fixedly connected to the second water outlet pipe 25. Several nozzles 31 are installed on the rear side of the cleaning tank 3. The input ends of the nozzles 31 are all fixedly connected to the second water outlet pipe 25 via pipes.

[0027] When the circulating cleaning component is working, the water storage tank 13 is located inside the rear of the equipment housing 1. Water is pumped to the outlet pipe 23 by the water pump 14. After flowing through the solenoid valve 22, the water enters the rotary joint 11 and is finally sprayed out through the nozzle 30 on the spray pipe 29. The bevel gear 33 fixedly sleeved at the bottom of the spray pipe 29 meshes with the bevel gear 34 at the output shaft end of the drive motor 10. The drive motor 10 drives the spray pipe 29 to rotate, which drives the nozzle 30 and the brush plate 32 fixed on its outer surface to rotate synchronously, cleaning the cleaning tank 3. The inner wall of the collapse cylinder 9 is subjected to rotating spraying and physical brushing to effectively remove stubborn residues. The cleaning wastewater flows into the sewage pipe 21 through the connecting channel 20 at the bottom front of the cleaning tank 3 and enters the filter frame 16 inside the return water tank 15 for solid-liquid separation. The filtered water flows back to the storage tank 13 to form a closed-loop circulation system, realizing the reuse of water resources. At the same time, the water flow of the outlet pipe 25 is controlled by the solenoid valve 24, which drives the nozzle 31 at the rear of the cleaning tank 3 to perform fixed-point rinsing on the discharge platform 2, further improving the thoroughness of cleaning.

[0028] The cleaning assembly includes an electric push rod 19, the bottom of which is hinged to the rear side of the equipment housing 1. The feeding platform 2 is hinged to the top front side of the equipment housing 1. The output shaft end of the electric push rod 19 is hinged to the bottom of the feeding platform 2. A scraper 12 is slidably mounted on the feeding platform 2. A mounting frame 26 is fixedly connected to the right side of the feeding platform 2. A screw 28 is rotatably passed between the front and rear sides of the mounting frame 26. A second drive motor 27 is fixedly mounted on the rear side of the mounting frame 26. The output shaft end of the second drive motor 27 is fixedly connected to the rear end of the screw 28. The right side of the scraper 12 is threaded onto the screw 28.

[0029] When the cleaning component is working, the bottom of the electric push rod 19 is hinged to the rear side inside the equipment box 1, and its output shaft is hinged to the bottom of the discharge platform 2. It can drive the discharge platform 2 to rotate around the hinge point as the axis, which makes it easy to pour out the residual concrete. The scraper 12, which is slidably installed on the discharge platform 2, drives the screw 28 to rotate through the drive motor 27 on the right mounting frame 26. The scraper 12 is threaded on the screw 28 and slides laterally along the surface of the discharge platform 2 as the screw 28 rotates, scraping the residual concrete to the edge, thus realizing automated cleaning.

[0030] The detection assembly includes a fixed column 4, a rotating cylinder 5 fixedly mounted on the top of the fixed column 4, an mounting plate 6 mounted on the top output end of the rotating cylinder 5, a cylinder 7 fixedly mounted on the top right side of the mounting plate 6, a lifting plate 8 fixedly connected to the output shaft end of the cylinder 7, a collapse cylinder 9 fixedly mounted on the right side of the lifting plate 8, and a laser rangefinder 17 and a CCD vision camera 18 mounted on the bottom left side of the mounting plate 6.

[0031] When the detection component is working, the rotating cylinder 5 at the top of the fixed column 4 drives the mounting plate 6 to rotate, thereby rotating the mounting plate 6. The cylinder 7 on the right side of the mounting plate 6 controls the vertical movement of the lifting plate 8, which precisely presses the slump cylinder 9 down onto the surface of the concrete to be tested. When the cylinder 7 retracts, the lifting plate 8 drives the slump cylinder 9 to be lifted vertically, allowing the concrete to collapse freely. At the same time, the mounting plate 6 rotates half a turn, and the laser rangefinder 17 measures in real time the difference between the highest point of the collapsed concrete and the original height of the slump cylinder 9. The CCD vision camera 18 simultaneously acquires images of the collapse shape, and the slump value is calculated through data fusion.

[0032] Working Principle: This concrete quality testing device for water conservancy projects uses the equipment housing 1 as its main frame. A cleaning pool 3 is located on the top left, and a discharge platform 2 is located on the right. During testing, the concrete to be tested is placed on the discharge platform 2. The rotating cylinder 5 at the top of the fixed column 4 drives the mounting plate 6 to rotate. The cylinder 7 on the right side of the mounting plate 6 controls the vertical movement of the lifting plate 8, precisely pressing the slump cylinder 9 down onto the surface of the concrete to be tested. When the cylinder 7 retracts, the lifting plate 8 lifts the slump cylinder 9 vertically, allowing the concrete to collapse freely. Simultaneously, the mounting plate 6 rotates half a turn, and the laser rangefinder 17 measures the distance between the highest point of the collapsed concrete and the ground surface in real time. The difference in the original height of the slump cylinder 9 is simultaneously acquired by the CCD vision camera 18, which captures images of the slump shape. The slump value is calculated through data fusion. After the test is completed, the bottom of the electric push rod 19 is hinged to the rear side inside the equipment box 1, and its output shaft is hinged to the bottom of the discharge platform 2. It can drive the discharge platform 2 to rotate around the hinge point as the axis, which is convenient for pouring out residual concrete. The scraper 12, which is slidably installed on the discharge platform 2, drives the screw 28 to rotate through the drive motor 27 on the right mounting frame 26. The scraper 12 is threaded on the screw 28 and slides laterally along the surface of the discharge platform 2 as the screw 28 rotates, scraping the residual concrete to the edge, thus achieving automated cleaning.

[0033] Meanwhile, since the water storage tank 13 is located inside the rear of the equipment housing 1, water is pumped to the outlet pipe 23 by the water pump 14. After flowing through the solenoid valve 22, the water enters the rotary joint 11 and is finally sprayed out through the nozzle 30 on the spray pipe 29. The bevel gear 33 fixedly sleeved at the bottom of the spray pipe 29 meshes with the bevel gear 34 at the output shaft end of the drive motor 10. The drive motor 10 drives the spray pipe 29 to rotate, causing the nozzle 30 and the brush plate 32 fixed on its outer surface to rotate synchronously, cleaning the slump in the cleaning tank 3. The inner wall of the drop cylinder 9 is subjected to rotating spray washing and physical brushing to effectively remove stubborn residues. The cleaning wastewater flows into the sewage pipe 21 through the connecting channel 20 at the bottom front of the cleaning tank 3 and enters the filter frame 16 inside the return water tank 15 for solid-liquid separation. The filtered water flows back to the storage tank 13 to form a closed-loop circulation system, realizing the reuse of water resources. At the same time, the water flow of the outlet pipe 25 is controlled by the solenoid valve 24, which drives the nozzle 31 at the rear of the cleaning tank 3 to perform targeted rinsing on the discharge platform 2, further improving the thoroughness of cleaning.
