Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampling equipment technology, specifically a cement testing and sampling device. Background Technology
[0002] Currently, cement sampling inside cement storage tanks mainly relies on traditional manual sampling devices or simple mechanical sampling devices. Existing technologies have the following shortcomings in sampling inside cement storage tanks:
[0003] Traditional sampling devices can mostly only sample the surface of cement storage tanks, making it difficult to effectively sample cement at different depths. Because cement stratifies during storage, especially inside the tank, the deposition and distribution of cement particles may change due to vibration, pressure, or the passage of time. Sampling results from a single depth cannot fully reflect the overall quality and characteristics of the cement.
[0004] Furthermore, most existing sampling devices cannot effectively control the accuracy of sampling, especially when sampling at different depths in cement storage tanks, where precise sampling control is difficult to achieve using conventional equipment. Existing devices lack effective depth adjustment capabilities, making it impossible to sample at different depths as needed, and the limitations of the equipment during operation may lead to deviations in the sampling results.
[0005] Therefore, existing cement sampling devices have certain limitations in terms of accuracy, depth control, and ease of operation. There is an urgent need for a cement sampling device that can achieve multi-depth sampling and has high accuracy and automation to meet the needs of modern cement storage tank management and quality testing. Utility Model Content
[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0007] Therefore, the technical solution adopted by this utility model is as follows: a cement testing sampling device, including: a tripod, a probe assembly, and a drill assembly, wherein the top of the tripod is provided with a collar, the probe assembly is slidably sleeved on the inner side of the collar, the drill assembly is fixed to the bottom end of the probe assembly, the probe assembly includes a sampling rod and an outer sleeve rotatably sleeved on the surface of the sampling rod, the surfaces of the sampling rod and the outer sleeve are respectively provided with a plurality of sample slots and valve holes arranged in a one-to-one correspondence, and the sample slots are opened by the overlap of the sample slots and valve holes under the deflection effect of the sampling rod, and the drill assembly includes a cone body and a polarization motor fixed inside the cone body.
[0008] In a preferred embodiment, the present invention can be further configured such that: a cable assembly is provided on the inner side of the sampling rod for power connection and start / stop control of the polarization motor.
[0009] Specifically, the high-frequency vibration of the polarization motor causes changes in the porosity between cement particles, thereby reducing friction and increasing particle flowability. This makes the surface of the cement powder more loose, allowing the drill bit assembly to gradually sink into the interior of the cement powder under vibration.
[0010] In a preferred embodiment, the present invention can be further configured such that the cone body is a cone structure and is made of tungsten steel.
[0011] Specifically, the downward movement of the probe assembly is guided by the gravity of the cone-shaped body, and the cone-shaped structure is used to increase the downward resistance of the probe assembly and drill bit assembly on the cement surface.
[0012] In a preferred embodiment, the present invention can be further configured such that: the sample groove on the surface of the sampling rod penetrates the sampling rod for sample storage, and the valve hole is adapted to the width of the sample groove.
[0013] In a preferred embodiment, the present invention can be further configured such that: the deflection limiting component is a spring abutment structure, and the inner side of the outer tube is provided with an abutment groove corresponding to the spring abutment, thereby using the deflection limiting component to achieve the deflection limiting of the outer tube.
[0014] In a preferred embodiment, the present invention can be further configured such that: a handle is provided at the top of the sampling rod, and a rotating ring is fixedly installed at the top of the outer tube, which facilitates gripping and manual deflection of the outer tube.
[0015] The beneficial effects achieved by this utility model are as follows:
[0016] 1. This invention, through its unique probe assembly design, enables precise sampling of cement at different depths within a cement storage tank. Unlike existing technologies, this device allows for sampling beyond the surface of the cement storage tank by adjusting the position of the probe assembly, thus covering deeper layers of cement and ensuring more comprehensive and representative samples.
[0017] 2. In this invention, the outer sleeve deflection mechanism and sample slot design make the sampling process more precise and effectively avoid sample deviation caused by equipment errors. Precise control of the deflection limiting component ensures accurate positioning of the sampling rod, thereby improving sampling accuracy and enabling the collected cement samples to more accurately reflect the quality and characteristics of the cement in the storage tank.
[0018] 3. In this invention, the high-frequency vibration effect of a polarization motor automatically increases the fluidity of cement particles, effectively achieving uniform sample collection. The vibration significantly improves the looseness of cement particles during sampling, reducing manual intervention and enhancing sampling efficiency and convenience.
[0019] Through the above improvements, this utility model not only solves the problems of precision and depth control in the existing technology, but also improves sampling efficiency and operational convenience, providing a more accurate and efficient solution for cement storage tank management and quality inspection.

[0031] Combination Figures 1-4As shown, the present invention provides a cement testing sampling device, comprising: a tripod 100, a probe assembly 200, and a drill assembly 300. The top of the tripod 100 is provided with a collar 110. The probe assembly 200 is slidably sleeved on the inner side of the collar 110. The drill assembly 300 is fixed to the bottom end of the probe assembly 200. The probe assembly 200 includes a sampling rod 210 and an outer sleeve 220 rotatably sleeved on the surface of the sampling rod 210. The surfaces of the sampling rod 210 and the outer sleeve 220 are respectively provided with a plurality of sample slots 211 and valve holes 221 arranged in a one-to-one correspondence. The sample slots 211 are opened by the overlap of the sample slots 211 and valve holes 221 under the deflection effect of the sampling rod 210. The drill assembly 300 includes a cone body 310 and a polarization motor 320 fixed on the inner side of the cone body 310. Through the synergistic action of the drill bit assembly 300 and the probe assembly 200, effective sampling of cement powder can be achieved, ensuring the accuracy and controllability of the sampling process.
[0032] In this embodiment, a cable assembly is provided inside the sampling rod 210 for power connection and start / stop control of the polarization motor 320.
[0033] Working effect: The cable group configuration allows for flexible control of the start and stop of the polarization motor 320, ensuring the continuous stability of the vibration effect during cement sampling and enhancing the sampling accuracy.
[0034] In this embodiment, the cone body 310 has a cone structure and is made of tungsten steel.
[0035] Performance: The use of a conical structure and tungsten steel material ensures that the drill bit assembly 300 has sufficient penetration power and wear resistance, enabling it to easily penetrate cement powder layers, avoid drill bit damage, and improve the durability and stability of the equipment.
[0036] In this embodiment, the sample groove 211 on the surface of the sampling rod 210 passes through the sampling rod 210 and is used for sample storage. The valve hole 221 is adapted to the width of the sample groove 211.
[0037] Working effect: The sample tank 211 is designed to be through-hole, which can effectively accommodate and store the sampled cement sample. Combined with the design of valve hole 221, it ensures the integrity and sealing of sample storage and avoids sample leakage.
[0038] In this embodiment, the deflection limiting component 212 is a spring abutment structure, and the inner side of the outer tube 220 is provided with an abutment groove corresponding to the spring abutment. The deflection limiting component 212 is used to achieve the deflection limiting of the outer tube 220.
[0039] Working effect: The spring abutment structure and the abutment groove work together to enable the outer tube 220 to precisely control the deflection angle, effectively preventing the outer tube 220 from deflecting excessively or getting stuck, and ensuring the smooth opening and closing of the sample groove 211.
[0040] In this embodiment, the sampling rod 210 has a handle at its top end, and the outer tube 220 has a rotating ring fixedly installed at its top end.
[0041] Working effect: The handle and swivel design allows operators to manually adjust the rotation angle of the outer sleeve 220, enhancing the operability of the equipment. It is suitable for sampling cement layers of different depths and improves the ease of operation.
[0042] Working principle and usage process of this utility model:
[0043] The working principle of this cement testing and sampling device is based on its unique structural design and the coordinated operation of its components, enabling effective sampling and testing of cement powder. The specific working principle is as follows:
[0044] 1. Overall Structure and Working Principle: This device mainly consists of a tripod 100, a probe assembly 200, and a drill bit assembly 300. The tripod 100 provides stable support and ensures the stability of the device during use. The probe assembly 200 is slidably fitted into the collar 110 at the top of the tripod 100, and the drill bit assembly 300 is fixed to the bottom end of the probe assembly 200. During operation, supported by the tripod, the probe assembly 200 and the drill bit assembly 300 can smoothly enter the cement powder layer to collect samples.
[0045] 2. Working Principle of the Drill Bit Assembly: The drill bit assembly 300 includes a conical body 310 and a polarization motor 320. The conical body 310 is made of tungsten steel, which has high density and weight. During sampling, the drill bit assembly 300, through its conical structure design, ensures that the drill bit can effectively penetrate the cement powder layer, and guides the probe assembly 200 downwards by gravity and the shape of the conical body. During this process, the polarization motor 320 utilizes high-frequency vibration to effectively reduce the friction between cement particles, promoting increased particle flowability and thus loosening the cement particles. High-frequency vibration causes changes in the voids between cement particles, promoting the loosening of cement powder and ensuring that the drill bit assembly 300 can smoothly sink into the cement.
[0046] 3. Working principle of the probe assembly: The probe assembly 200 includes a sampling rod 210 and an outer sleeve 220. The sampling rod 210 has a sample groove 211 and a valve hole 221 on its surface. After the entire probe assembly 200 enters the cement, the outer sleeve 220 is manually rotated 90 degrees to open the sample groove 211 for sampling. This allows for separate sampling of cement layers at different depths.
[0047] 4. Sample Collection and Storage: Under the combined action of the drill bit assembly 300 and the probe assembly 200, cement particles are loosened by vibration, and cement samples are collected and enter the sample slots 211 within each sampling rod 210. The outer sleeve 220 is then deflected 90 degrees again to seal the sample slots 211, preserving the samples inside. In this way, the device can continuously and effectively sample cement powder and store the samples.
