Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sampling and testing equipment, specifically a sampling device for hydrogen detection in waterproof mortar. Background Technology
[0002] Hydrogen in mortar mainly exists in the form of water and participates in the hydration reaction of cement. Although hydrogen itself does not negatively affect the performance of mortar, it can combine with alkaline substances produced during cement hydration, potentially leading to efflorescence. Anti-efflorescence agents are typically used to prevent this, thereby improving the performance and appearance of the mortar. After mortar mixing, sampling equipment is usually used for testing, primarily to monitor the water-cement ratio and avoid problems such as excessive water addition leading to efflorescence or insufficient mortar strength later on.
[0003] Traditional cement mortar sampling devices typically use a single sampling tube to sample the cement mortar. Completing multi-layer sampling requires multiple repetitions, which has several drawbacks in practical use. For example, multi-layer sampling requires multiple start-stop cycles, resulting in low efficiency. When collecting samples at different depths, the sampling tube must be pulled out, the depth adjusted, and then reinserted. A single sampling process involves three steps: lowering, sampling, and pulling out, and these repeated operations severely impact testing efficiency. Furthermore, due to the lack of synchronicity and representativeness in samples collected over time, the mortar may undergo initial setting or moisture migration during the sampling intervals (e.g., surface moisture evaporates faster), leading to inconsistent sample properties across layers. Each time the sampling tube is pulled out, it can also cause surrounding mortar to flow, resulting in lower-layer aggregate mixing into upper layers, disrupting the original state of the sample layers and distorting the homogeneity test results. Utility Model Content
[0004] One of the technical problems that this application aims to solve is that traditional cement mortar sampling devices usually use a single sampling tube to sample cement mortar, and multiple repeated operations are required to complete multi-layer sampling, which has many shortcomings in practical use.
[0005] To address the aforementioned technical problems, this application provides a sampling device for detecting hydrogen energy in waterproof mortar, comprising two side support plates, each with a sliding plate. A bracket is fixedly installed at the lower center of the sliding plate, and a fixing plate is threadedly connected to the lower end of the bracket by screws. A slot is formed in the center of the fixing plate, and a sampling cylinder is inserted into the center of the slot. A pad is fixedly installed at the upper end of the sampling cylinder, and a sleeve is snapped into the lower end of the sampling cylinder. Multiple sampling ports are evenly formed in the center and above and below the center of the sampling cylinder. An insertion rod is provided in the center of the sampling cylinder, and sealing collection plates are fixedly installed in the center and above and below the insertion rod. A cylinder is fixedly installed in the center of the upper end of the sliding plate, and the output end of the cylinder passes through the bracket and the upper end of the insertion rod and is fixedly connected by screws.
[0006] In some embodiments, a base is fixedly installed at the lower end of each of the two side support plates, and a sliding groove is provided in the middle of each of the two side support plates, with the sliding plate slidably engaged in the middle of the two sliding grooves.
[0007] In some embodiments, a lead screw is rotatably mounted in the middle of one of the slides, and a guide rod is fixedly mounted in the middle of the other slide.
[0008] In some embodiments, a motor is fixedly installed in the middle of the upper end of one of the side support plates, the output end of the motor is fixedly connected to one end of a lead screw, the lead screw is threadedly connected to the middle of one end of the slide plate, and the guide rod is slidably engaged in the middle of the other end of the slide plate.
[0009] In some embodiments, the pad is snapped onto the upper end of the middle of the slide plate, and the sealing aggregate plate is slidably snapped onto the middle of the sampling cylinder and abuts against the inner wall of the sampling cylinder.
[0010] In some embodiments, the thickness of the sealing collection plate is greater than the opening size of the corresponding sampling port, and a collection space is formed between two adjacent sealing collection plates.
[0011] This utility model has at least the following beneficial effects:
[0012] 1. When in use, this utility model can achieve multi-depth synchronous sampling of waterproof mortar. Through the linkage design of the multi-layer sampling port in the middle and above and below the sampling tube with the sealing aggregate plate, mortar samples of different depths such as surface, middle and bottom layers can be collected simultaneously in one operation, avoiding the time difference and human disturbance of traditional segmented sampling. The samples of each layer are collected at the same time point, eliminating the difference in material aging, making the results of hydrogen energy detection more comparable, and can truly reflect the stratification and segregation of mortar or its uniformity.
[0013] 2. When in use, this utility model uses a cylinder to drive the sealing collection plate to open or close the sampling port synchronously, eliminating the need for manual contact with the mortar, thus reducing labor intensity and pollution risk; and the screw drive combined with the guide rod can effectively reduce the sliding plate lifting error, ensuring that the sampling tube is inserted vertically into the target depth and avoiding sample deviation caused by tilting.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: a sampling device for hydrogen detection in waterproof mortar, comprising two side support plates 1, each with a sliding plate 2. A bracket 21 is fixedly installed at the lower center of the sliding plate 2. A fixing plate 22 is threadedly connected to the lower end of the bracket 21 by screws. A slot 25 is formed in the middle of the fixing plate 22, and a sampling cylinder 26 is inserted into the middle of the slot 25. A pad 28 is fixedly installed at the upper end of the sampling cylinder 26, and a sleeve 27 is snapped into the lower end of the sampling cylinder 26. Multiple sampling ports 29 are evenly formed in the middle and above and below the middle of the sampling cylinder 26. A rod 30 is provided in the middle of the sampling tube 26. Sealing collection plates 31 are fixedly installed in the middle and above and below the rod 30. A cylinder 23 is fixedly installed in the middle of the upper end of the slide plate 2. The output end of the cylinder 23 passes through the bracket 21 and the upper end of the rod 30 and is fixedly connected by screws. The pad 28 is snapped into the upper end of the middle of the slide plate 2. The sealing collection plate 31 is slidably snapped into the middle of the sampling tube 26 and abuts against the inner wall of the sampling tube 26. The thickness of the sealing collection plate 31 is greater than the opening size of the corresponding sampling port 29. A collection space is formed between two adjacent sealing collection plates 31.
[0022] In this embodiment, by uniformly opening multiple sampling ports 29 in the middle and above and below the sampling cylinder 26, and forming independent collection spaces between adjacent sealing aggregate plates 31, mortar samples at different depths can be collected simultaneously in one operation, avoiding detection deviations caused by mortar segregation. This is particularly suitable for evaluating the uniformity of materials such as premixed mortar and concrete. In the initial state, the thickness of the sealing aggregate plate 31 is greater than the opening of the sampling port 29, which can completely seal the sampling port 29 and prevent shallow mortar from entering the collection space in advance during the lowering process, thus affecting the accuracy of sample collection. During sampling, the insertion rod is driven by the cylinder 23. The 30 drives the sealing collection plate 31 to move synchronously, so that the sampling ports 29 of each layer open or close at the same time, ensuring that mortar samples of different depths can be collected at the same time, making the data more comparable; the sampling tube 26 is snapped into the sleeve 27, and the fixing plate 22 is threaded into the bracket 21, which facilitates disassembly, cleaning or replacement of sampling groups of different specifications. The sealing collection plate 31 is tightly against the inner wall of the sampling tube 26, and with the guidance of the sliding plate 2 and the side support plate 1, it prevents mortar from seeping into the adjacent collection space from the gap during the sampling process, ensuring the purity of the samples of each layer, and the spacing of the sampling ports 29 can be customized according to the requirements.
[0023] Example 2: As Figures 1-2 As shown, a base 11 is fixedly installed at the lower end of each of the two side support plates 1. A sliding groove 12 is opened in the middle of each of the two side support plates 1. The slide plate 2 is slidably engaged in the middle of the two sliding grooves 12. A lead screw 13 is rotatably installed in the middle of one of the sliding grooves 12. A guide rod 15 is fixedly installed in the middle of the middle of the upper end of one of the side support plates 1. The output end of the motor 14 is fixedly connected to one end of the lead screw 13. The lead screw 13 is threadedly connected to the middle of one end of the slide plate 2. The guide rod 15 is slidably engaged in the middle of the other end of the slide plate 2.
[0024] In this embodiment, the height of the slide plate 2 is adjustable. The two bases 11 can make the side support plate 1 more securely fixed in the designated position. The middle of the two side support plates 1 is provided with a sliding groove 12. The middle of one base 11 is equipped with a lead screw 13 driven by a motor 14, and the middle of the other base 11 is equipped with a guide rod 15. The two ends of the slide plate 2 are respectively threaded to the lead screw 13 and slidably engaged with the guide rod 15. The user can drive the lead screw 13 to rotate by the motor 14, thereby driving the slide plate 2 to slide up and down along the sliding groove 12, thereby adjusting the distance between the sampling cylinder 26 below the slide plate 2 and the mortar sample to be collected. During adjustment, the guide rod 15 can make the slide plate 2 move more smoothly.
[0025] like Figures 1-5As shown, before use, the device is fixed in the designated position. Then, the mixed waterproof mortar is placed below the sampling cylinder 26. During use, the sleeve 27 is removed, and the motor 14 drives the lead screw 13 to rotate, which in turn drives the slide plate 2 to slide up and down along the slide groove 12, thereby adjusting the distance between the sampling cylinder 26 below the slide plate 2 and the mortar sample to be collected. After reaching the designated depth, the cylinder 23 is activated, and the piston rod extends to push the insertion rod 30 downward. The insertion rod 30 drives all the sealing collection plates 31 to move down synchronously, so that the sampling ports 29 of each layer open at the same time. Under the action of gravity and lateral pressure, the mortar flows into the sampling port 29. During sample collection, the cylinder 23 should be extended for a period of time to ensure that the mortar at each depth is fully filled in the collection space between adjacent sealed collection plates 31, so that samples at different depths are independently sealed in the corresponding collection space. Then, the cylinder 23 is retracted, which drives the insertion rod 30 and the sealed collection plate 31 to move upward, re-seal the sampling port 29 to prevent sample overflow or contamination. The starting motor 14 reverses the drive screw 13 to drive the slide plate 2 to rise, and the sampling tube 26 is pulled out of the mortar at a uniform speed. The connecting screws of the fixing plate 22 and the bracket 21 are unscrewed, and the sampling tube 26 is removed to detect the hydrogen energy inside the mortar.
