Description

Technical Field

[0001] This utility model relates to the field of microbial concrete testing devices, specifically to a microbial self-healing concrete testing device that is easy to adjust. Background Technology

[0002] Self-healing concrete is a new type of composite material that mimics the regeneration and recovery mechanism of animal bone tissue after injury. It uses a combination of repair adhesive and concrete materials to achieve self-repair and regeneration of damaged materials, restoring or even improving material properties.

[0003] This new material is currently in the experimental stage, meaning it has not been put into large-scale use. Its functions and effects have not yet been perfected to a mature stage, so a large number of tests are needed to verify its reliability.

[0004] The purpose of this experimental device for this new material is to compress a sample (i.e., a standardized concrete block) to create a crack as required by the experiment, then leave it for a period of time to observe its self-healing effect. This experiment is repeated, and then targeted improvements are made. This is the function of the experimental device.

[0005] However, most existing experimental devices use a press to compress cracks in one go, that is, directly input a fixed power and output sufficient pressure at once. Since the generation of cracks is uncontrollable, this full output can easily cause some samples to fail to meet the requirements, resulting in sample waste, and also affecting the experimental results and the psychological state of the operators.

[0006] Therefore, an adjustable experimental device is needed that can significantly reduce the defect rate of cracked products and lower experimental costs. Utility Model Content

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0019] like Figure 1 , Figure 2 As shown, an easily adjustable microbial self-healing concrete testing device includes a base 1, a collection trough 2 fixedly installed at the top of the base 1, a graduated cylinder 3 fixedly installed at the bottom of the collection trough 2, the graduated cylinder 3 communicating with the collection trough 2, a fixing frame 4 fixedly installed at the top of the base 1, an electric telescopic rod 5 fixedly installed on the fixing frame 4, a water tank 6 fixedly installed at the output end of the electric telescopic rod 5, an adjustable pressure pump 8 fixedly installed on the fixing frame 4, the output end of the adjustable pressure pump 8 being fixedly connected to and communicating with the water tank 6 via a hose, a water tank 11 fixedly installed at the top of the base 1, a water pump installed inside the water tank 11, an inlet pipe 9 fixedly connected to the top of the water tank 11, one end of the inlet pipe 9 being fixedly connected to the input end of the adjustable pressure pump 8, and the bottom of the water tank 11... A return water pipe 10 is fixedly connected to the end of the graduated cylinder 3. The return water pipe 10 is fixedly connected to and communicates with the bottom of the graduated cylinder 3. During the experiment, the sample is placed on the collection tank 2, and then the electric telescopic rod 5 is activated to lower the water tank 6, thereby initially stabilizing the sample and facilitating subsequent squeezing. When cracks appear, the adjustable pressure pump 8 is activated to fill the water tank 6 with water. After the water permeates into the collection tank 2 below, the reading on the graduated cylinder 3 is observed to determine the permeability per unit time. After obtaining the corresponding result, the valve on the return water pipe 10 is opened to allow the water to flow back into the water tank 11. In addition, the adjustable pressure pump 8 can adjust the output power, which can effectively change the water pressure and flow rate, thereby making the experimental data more accurate and diverse.

[0020] A temperature controller 7 is fixedly installed on the side wall of the water tank 6. The heat exchange component of the temperature controller 7 extends into the water tank 6. The internal water temperature is controlled by the temperature controller 7. Depending on the material selected for the experiment, the temperature is adjusted to different temperatures to observe the repair effect of the repair material at different temperatures, thereby improving the reliability of the data. At the same time, after selecting a suitable temperature, the experimental efficiency can also be accelerated.

[0021] Rubber sealing gaskets are fixedly installed at the bottom of the water tank 6 and the top of the collection tank 2 to ensure airtightness and thus obtain a stable permeability.

[0022] A bracket is fixedly installed at the top of the base 1, and a cylinder 24 is fixedly installed on the bracket. A second side pressure plate 25 is fixedly installed at the output end of the cylinder 24, and the cylinder 24 provides sufficient pressure.

[0023] A side pressure frame 12 is fixedly installed at the top of the base 1. The side pressure frame 12 consists of a support rib and a return plate. A through groove 13 is provided on the return plate. The through groove 13 is square in shape. A first side pressure plate 14 is slidably connected in the through groove 13. A threaded cylinder 15 is fixedly installed on one side of the first side pressure plate 14. A threaded rod 16 is threadedly connected in the threaded cylinder 15. One end of the threaded rod 16 is rotatably connected to the inner wall of the return plate. A gear 17 is fixedly sleeved on the threaded rod 16. A toothed plate is meshed on one side of the gear 17. 18. The toothed plate 18 is L-shaped. A dovetail block 19 is fixedly installed on one side of the toothed plate 18. A dovetail groove 20 is provided on the molded plate. The dovetail block 19 extends into the dovetail groove 20 and is slidably connected to it. A scale rod 21 is fixedly connected to the molded plate. An adjusting block 22 is slidably connected to the scale rod 21. A bolt is screwed onto the adjusting block 22. The top end of the scale rod 21 passes through the toothed plate 18 and is slidably connected to it. A hydraulic cylinder 23 is fixedly connected to the bottom end of the toothed plate 18. The bottom end of the hydraulic cylinder 23 is fixedly installed on... On base 1, after the sample is initially fixed, cylinder 24 is activated to initially compress the sample. At this time, the output power of cylinder 24 is less than the specified power. The resulting compression effect is that the cracks may reach the acceptable level, but most cracks are less than the specified length, greatly preventing the cracks from exceeding the limit, thereby reducing the sample rejection rate and experimental costs. Observe the sample cracks, select an appropriate pressure value, and then adjust the adjusting block 22 to the appropriate distance on the scale rod 21 and lock it with bolts. Then, activate hydraulic cylinder 23 to retract, causing toothed plate 18 to descend and drive gear 17 to rotate slowly, which in turn causes threaded rod 16 to rotate slowly. Threaded cylinder 15 slowly drives the first side pressure plate 14 to continue compressing the sample. The operator can easily observe the continued generation of cracks. Repeat the above operation. After repeated slow pressurization, the cracks in the sample can meet the specified range to the greatest extent, thus facilitating subsequent experiments.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
