Description

Technical Field

[0001] This utility model belongs to the technical field of concrete testing equipment, specifically a concrete detector resistant to water erosion in saline-alkali soil. Background Technology

[0002] In the construction industry of saline-alkali areas, concrete structures are subjected to long-term erosion by saline-alkali soil and water, which significantly reduces the mechanical and durability properties of concrete, seriously threatening the safety and service life of construction projects. Therefore, accurate testing of the concrete's resistance to saline-alkali soil and water erosion has become a crucial step in ensuring the quality of construction projects in saline-alkali areas.

[0003] Current testing equipment for concrete resistance to saline-alkali soil water erosion has significant shortcomings. Firstly, most testing devices can only test concrete under single static conditions, such as providing a fixed concentration of saline-alkali solution and maintaining a constant temperature, lacking dynamic effects. This fails to simulate the complex and variable saline-alkali soil water erosion environment, resulting in significant discrepancies between the test results and actual erosion conditions in engineering projects, making it difficult to accurately reflect the concrete's erosion resistance under real-world conditions. Secondly, existing testing equipment uses limited monitoring methods for parameters, failing to comprehensively and accurately acquire multi-dimensional data on concrete during saline-alkali soil water erosion, such as changes in solution concentration, concrete quality, and the dynamic changes in erosion rate over time and with environmental factors. This hinders in-depth analysis of the mechanism of concrete erosion resistance. Thirdly, the existing detectors have inadequate structural design and cumbersome operation procedures, leading to low testing efficiency and increased time and economic costs. Therefore, innovative design and optimization of concrete saline-alkali soil water erosion detectors are urgently needed to effectively overcome the aforementioned problems of poor testing results, incomplete monitoring, and inconvenient operation. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a concrete saline-alkali soil water erosion detector with the advantage of good detection effect.

[0005] This utility model provides the following technical solution: a concrete saline-alkali soil water erosion detector, comprising a support frame, a detection cylinder rotatably connected inside the support frame, teeth fixedly connected to the surface of the detection cylinder, the number of teeth being several, and the teeth being evenly distributed in a ring on the surface of the detection cylinder, a first motor fixedly connected to the surface of the support frame via a bracket, a gear fixedly connected to the output end of the first motor, the gear meshing with the teeth, a discharge valve connected to the bottom of the detection cylinder, a stirring rod fixedly connected to the inner wall of the detection cylinder, the number of stirring rods being several, and the stirring rods being evenly distributed in a ring on the inner wall of the detection cylinder, a drive box fixedly connected to the top of the support frame, a first threaded rod rotatably connected inside the drive box, and the drive... The internal cavity of the housing has a sliding connection to a movable column, which is threadedly connected to a first threaded rod. A second motor is fixedly connected to the top of the drive housing, and the output end of the second motor is fixedly connected to the first threaded rod. A cover plate is fixedly connected to the bottom of the movable column, and the bottom of the cover plate fits against the top of the detection cylinder. A support frame is fixedly connected to the bottom of the cover plate, and there are several support frames evenly distributed in a ring on the bottom of the cover plate. A support plate is fixedly connected to the surface of the support frame, and there are several openings evenly distributed on the surface of the support plate. A fixed frame is fixedly connected to the right side of the drive housing, and a weighing device is fixedly connected to the top of the fixed frame. A heating rod is fixedly connected inside the support frame.

[0006] The beneficial effects of this utility model are as follows: 1. This utility model uses a mixture of alkali, salt, and water in the testing cylinder to simulate a saline-alkali environment. A heating rod is also installed to adjust the water temperature to change the molecular motion rate and accelerate the erosion process. The first motor drives the testing cylinder to rotate, which in turn drives the stirring rod to ensure that the liquid and concrete block come into full and uniform contact. This can simulate the actual complex saline-alkali soil water erosion environment. Compared with traditional single static testing, it effectively reduces the deviation between the test results and the actual situation, and more accurately reflects the erosion resistance of concrete in actual engineering. This device has the advantage of good testing effect.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] like Figures 1 to 6 As shown, the concrete saline-alkali soil water erosion detector of this embodiment includes a support frame 1, a detection cylinder 2 rotatably connected inside the support frame 1, teeth 3 fixedly connected to the surface of the detection cylinder 2, the number of teeth 3 being several, and the teeth 3 being evenly distributed in a ring on the surface of the detection cylinder 2, a first motor 5 fixedly connected to the surface of the support frame 1 via a bracket, a gear 6 fixedly connected to the output end of the first motor 5, the gear 6 meshing with the teeth 3, a discharge valve 4 connected to the bottom of the detection cylinder 2, a stirring rod 7 fixedly connected to the inner wall of the detection cylinder 2, the number of stirring rods 7 being several, and the stirring rods 7 being evenly distributed in a ring on the inner wall of the detection cylinder 2, a drive box 8 fixedly connected to the top of the support frame 1, a first threaded rod rotatably connected inside the drive box 8, and a movable column 10 slidably connected inside the drive box 8. The movable column 10 is threadedly connected to the first threaded rod. The top of the drive box 8 is fixedly connected to the second motor 9, and the output end of the second motor 9 is fixedly connected to the first threaded rod. The bottom of the movable column 10 is fixedly connected to the cover plate 11, and the bottom of the cover plate 11 is in contact with the top of the detection cylinder 2. The bottom of the cover plate 11 is fixedly connected to the support frame 12. There are several support frames 12, which are evenly distributed in a ring at the bottom of the cover plate 11. The surface of the support frame 12 is fixedly connected to the support plate 13. The surface of the support plate 13 has openings 14, which are evenly distributed on the surface of the support plate 13. The right side of the drive box 8 is fixedly connected to the fixed frame 17, and the top of the fixed frame 17 is fixedly connected to the weighing device 18. The inside of the support frame 12 is fixedly connected to the heating rod 15.

[0016] refer to Figure 2 The surface of the detection cylinder 2 is provided with observation ports 25. There are several observation ports 25, which are evenly distributed in a ring on the surface of the detection cylinder 2. A transparent plate 26 is fixedly connected inside the observation port 25.

[0017] In this embodiment, through the setting of the observation port 25 and the transparent plate 26, the operator can observe the water level in the detection cylinder 2 or the state of the concrete placed on top of the support plate 13 in the detection cylinder 2 through the transparent plate 26.

[0018] refer to Figure 4 A positioning ring 16 is fixedly connected to the top of the detection cylinder 2, and the positioning ring 16 is slidably connected to the cover plate 11.

[0019] In this embodiment, the positioning ring 16 increases the contact area between the detection cylinder 2 and the cover plate 11. At the same time, the operator can fix a rubber ring on the inner wall of the positioning ring 16 as needed. The rubber ring is in close contact with the cover plate 11, thereby increasing the sealing between the cover plate 11 and the detection cylinder 2, and thus preventing the external environment from affecting the environment inside the detection cylinder 2.

[0020] refer to Figure 1 The bottom of the support frame 1 is fixedly connected with several casters 21, which are evenly distributed at the bottom of the support frame 1.

[0021] This embodiment, through the provision of the universal wheel 21, facilitates the operator's movement of the device, thereby improving the portability of the device. The universal wheel 21 itself has a self-locking structure. The aforementioned universal wheel 21 is a common existing technology, and will not be described in detail in this application.

[0022] refer to Figure 1 Positioning blocks 22 are fixedly connected to the front and rear sides of both sides of the support frame 1. The internal threads of the positioning blocks 22 are connected to the second threaded rod 23. The bottom of the second threaded rod 23 is fixedly connected to the support pad 24. The top of the second threaded rod 23 is fixedly connected to the handle. The surface of the handle is provided with anti-slip texture, and the number of anti-slip textures is several.

[0023] In this embodiment, by setting up the positioning block 22, the second threaded rod 23 and the support pad 24, when the device is moved to a suitable position, the operator rotates the second threaded rod 23, which in turn drives the second threaded rod 23 and the support pad 24 to move down until the support pad 24 is in close contact with the ground, thereby preventing the device from shaking randomly and improving the stability of the device.

[0024] refer to Figure 1 The top of the support frame 1 is fixedly connected with a reinforcing frame 19, and there are several reinforcing frames 19. The reinforcing frames 19 are fixedly connected to the drive box 8. The left side of the support frame 1 is fixedly connected with a protective frame 20, and there are several protective frames 20.

[0025] In this embodiment, the stability of the drive box 8 can be improved by setting the reinforcing frame 19, and the operation can be prevented from being injured by the operator accidentally touching the first motor 5 or the gear 6 by setting the protective frame 20.

[0026] An appropriate amount of alkali and salt is placed in the detection cylinder 2, which contains water. The salt and alkali dissolve in the water, simulating a saline-alkali environment. The operator then places the concrete block to be tested on top of the support plate 13 and starts the second motor 9 to rotate, which in turn rotates the first threaded rod, causing the movable column 10, cover plate 11, support frame 12, support plate 13, and concrete block to move downwards until the concrete block is submerged in water. The water in the detection cylinder 2 gradually seeps into the concrete block, eroding it. The mass of the concrete block changes after erosion. For example, during the experiment, the operator activates the heating rod 15 to heat the water in the detection cylinder 2, increasing the molecular motion rate and thus increasing the erosion rate of the concrete block, thereby reducing the impact on the experimental setup. Meanwhile, the operator can start the first motor 5 to rotate, which drives the gear 6 to rotate, and then drives the detection cylinder 2 to rotate through the teeth 3. The rotation of the detection cylinder 2 drives the stirring rod 7 to rotate, which in turn drives the water in the detection cylinder 2 to stir, so that the liquid in the detection cylinder 2 comes into uniform contact with the concrete block, thereby improving the detection effect. After the detection time is up, the operator adjusts the support plate 13 to move upward, and then the operator places the concrete block on the top of the weighing device 18 and weighs the concrete block at this time. The weight of the concrete block is compared with the weight of the concrete block before the erosion test. Alternatively, multiple devices can be set up to set different salinity, temperature or erosion time conditions to test the change in the weight of the concrete block before and after the erosion test. The resistance of the concrete block to saline-alkali soil water erosion can be tested by comparative experiments.

[0027] The operator can install a pH meter at the bottom of the support plate 13 to detect the pH value of the liquid in the detection cylinder 2, thereby facilitating the operator to accurately adjust the pH value in the detection cylinder 2 and improving the detection accuracy of the device. The heating rod 15, the weighing device 18 and the pH meter are all existing common technologies and are common knowledge to those skilled in the art. This application will not elaborate on them in detail. After the experiment, the operator opens the discharge valve 4 to discharge the water in the detection cylinder 2.
