Description

Technical Field

[0001] This utility model relates to the field of automatic wax sealing technology, specifically to an automatic wax sealing device for on-site sampling. Background Technology

[0002] Drilling to collect soil samples for geotechnical testing is a method used in geotechnical investigations to understand the physical and mechanical properties of soil layers. Currently, soil sampling during drilling primarily involves using rotary samplers or thin-walled samplers. The sample container is then immediately sealed manually with tape and wax at the sealing opening. Existing methods are time-consuming and labor-intensive. Furthermore, manual wax sealing is susceptible to operational errors; if the wax seal is not completely tight, moisture in the collected soil sample will evaporate, reducing the soil's natural density and thus affecting parameters such as void ratio and liquid index. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic wax-sealing device for on-site sampling. This addresses the problems of existing methods being time-consuming and labor-intensive, and manual wax sealing being affected by operational factors. When the wax seal cannot be made dense, it can lead to the evaporation of moisture from the soil sample, resulting in a decrease in the natural density of the soil layer and thus affecting parameters such as porosity and liquid index.

[0004] One embodiment of this utility model provides an automatic wax-sealing sample device for on-site sampling, characterized in that it includes: Storage device for storing wax; A transmission device, connected to the storage device, is used to receive and process wax from the storage device; A wax sealing device, connected to the transmission device, is used to receive the processed wax and seal the sample with wax.

[0005] This utility model discloses an automatic wax-sealing sample device for on-site sampling. The storage device is mainly a sealed wax storage device for storing solid wax. The transmission device includes a heating device, a pressurizing device, and a transport channel. The heating device mainly liquefies the solid wax, and the pressurizing device transports the liquefied wax through the transport pipe to the wax-sealing device. The wax-sealing device includes clamps and a cooling device. The clamp consists of two layers of stainless steel, with the inner wall diameter slightly larger than the sample box diameter. It holds the soil sample sealed with adhesive tape. A 5cm gap is left between the inner and outer walls. A cooling device is used to rapidly cool the sealed liquid wax. After obtaining the undisturbed soil sample using a rotary soil sampler during drilling, the sample is placed in the sample box, sealed with adhesive tape, and fixed on the wax sealing device. The top cover is closed, and liquid wax is transported into the wax sealing device through a heating device, a pressurizing device, and a transport pipe. When the pressure gauge on the pressurizing device reaches 0.1 MPa, pressurization is stopped, and the wax is rapidly cooled by water. This mechanized wax sealing method saves time and labor, improving sample sealing efficiency. Compared to manual wax sealing, this invention provides a better sealing effect and significantly reduces the possibility of poor airtightness. This sample storage method allows the test results obtained from geotechnical tests to better reflect the actual state of the soil and rock layers, providing better guidance for providing soil and rock parameters.

[0007] In one embodiment, the transmission device includes: A heating device for heating wax; A pressurizing device used to apply pressure to the wax; Transport channels are used to transport wax from storage devices to wax sealing devices.

[0008] In one embodiment, the wax sealing device includes: A clamp used to hold a sample to be wax-sealed; A cooling device is used to cool the wax applied to the sample and allow it to solidify.

[0009] In one embodiment, the clamp is located in the wax-coated area and adjacent to the cooling device.

[0010] In one embodiment, the cooling device is located on one side of the wax-coated area.

[0011] In one embodiment, the storage device, the transmission device, and the wax sealing device are sequentially connected to form an integrated wax sealing device.

[0012] The above technical solution provides an automatic wax-sealing sample device for on-site sampling, which has the following beneficial effects: 1. Wax sealing provides better airtightness and can better preserve the moisture content of the original sample.

[0013] 2. Compared with traditional manual wax sealing, this invention can greatly improve wax sealing efficiency, save manpower, and increase efficiency. Attached Figure Description

[0017] The above detailed description is a specific description of a feasible embodiment of the present utility model. This embodiment is not intended to limit the patent scope of the present utility model. All equivalent implementations or modifications that do not depart from the so-called equivalent implementations or modifications of the present utility model should be included in the patent scope of this case.

[0018] Combination Figure 1 As shown, one embodiment of this utility model provides an automatic wax-sealing sample device for on-site sampling, characterized in that it includes: a storage device 100 for storing wax; A transmission device 200, connected to the storage device 100, is used to receive and process wax from the storage device 100; The wax sealing device 300 is connected to the transmission device 200 and is used to receive the processed wax and seal the sample with wax.

[0019] This utility model discloses an automatic wax-sealing sample device for on-site sampling. The storage device 100 is mainly a sealed wax storage device 110 for storing solid wax. The transmission device 200 includes a heating device 210, a pressurizing device 220, and a transport channel 230. The heating device 210 mainly liquefies the solid wax, and the pressurizing device transports the liquefied wax through the transport pipe to the wax sealing device 300. The wax sealing device 300 includes a clamp 310 and a cooling device 320. The clamp 310 is composed of two layers of stainless steel, with the inner wall diameter slightly larger than the sample box diameter. It is used to hold the soil sample sealed with adhesive tape. A 5cm gap is left between the inner and outer walls. The liquid wax is rapidly cooled by water through the cooling device 320. After the original soil sample is taken by a rotary soil sampler in the borehole, the sample is placed in the sample box, sealed with adhesive tape, and fixed on the wax sealing device 300. The top cover is closed, and the liquid wax is transported to the wax sealing device 300 through the heating device 210, the pressurizing device 220, and the transport pipe. When the pressure gauge of the pressurizing device 220 shows a pressure of 0.1 MPa, pressurization is stopped, and the wax is rapidly cooled by water through the cooling device 320. With the above devices, mechanized wax sealing is more time-saving and labor-saving, and improves the sample sealing efficiency. Compared with manual wax sealing, the wax sealing effect of this invention is better, and the possibility of poor air tightness is greatly reduced. This method of storing samples makes the test results obtained from geotechnical tests more reflective of the actual state of the soil and rock layers, and has better guiding significance for providing soil and rock parameters.

[0020] It should be noted that by integrating three core modules—storage, transmission, and wax sealing—a fully automated wax sealing process is achieved. This solves the problem of inefficiency in manual operation, replaces manual wax application and sealing steps, and significantly improves on-site sampling efficiency.

[0024] In this embodiment, the heating device 210 is used to melt the solid wax to a flowable state to adapt to automated conveying, and the pressurizing device 220 is used to push the molten wax through the transport channel 230 quickly to avoid blockage. The transport channel 230 is used to precisely guide the wax liquid to the wax sealing position, and together ensure the controllable conveying of the wax liquid, providing the necessary conditions for uniform and dense wax coating and solving the problem of poor air tightness.

[0025] In one embodiment, the heating device 210 is disposed on or connected to the transport channel 230.

[0026] In this embodiment, the heating device 210 is disposed on or connected to the transport channel 230 to ensure that the heat acts directly on the wax liquid during transport, thereby preventing the wax liquid from cooling and solidifying and maintaining a suitable viscosity and fluidity for coating.

[0028] In this embodiment, the pressurizing device 220 is installed on or connected to the transport channel 230, and the pressure is applied directly to the wax liquid in the transport channel 230 to prevent the wax liquid from stagnating and to ensure continuous and rapid supply to the wax sealing point.

[0029] In one embodiment, the wax sealing device 300 includes: Clamp 310 is used to hold the sample to be wax sealed; Cooling device 320 is used to cool the wax coated on the sample to allow it to solidify.

[0030] In this embodiment, the clamp 310 is used to fix the sample to prevent displacement and ensure that the wax layer is completely wrapped. The cooling device 320 is used to quickly solidify the wax layer to form a sealing shell, realize a mechanized sealing closed loop, replace manual holding and natural cooling, and solve the problem of poor sealing.

[0031] In one embodiment, the clamp 310 is located in the wax coating area 400 and adjacent to the cooling device 320.

[0032] In this embodiment, the waxing and cooling processes are physically connected, which improves the continuity of the process, avoids sample movement that could cause damage to the wax layer, and accelerates the "coating-curing" process.

[0033] In one embodiment, the cooling device 320 is disposed on one side of the wax coating area 400.

[0034] In this embodiment, the cooling device 320 is disposed on one side of the wax coating area 400 to shorten the exposure time of the wax liquid, quickly solidify and reduce the exposure of the sample to air, and maintain the natural moisture content of the soil sample.

[0035] In one embodiment, the storage device 100, the transmission device 200, and the wax sealing device 300 are sequentially connected to form an integrated wax sealing device.

[0036] In this embodiment, the storage device 100, the transmission device 200, and the wax sealing device 300 improve the overall process, reduce the failure rate, and are suitable for continuous operation.
