Description

Technical Field

[0001] The utility model belongs to the technical field of geological prospecting technology, and in particular relates to a standard penetrator which is convenient for cleaning. Background Art

[0002] The standard penetrometer is an important component of the standard penetrometer, which is mainly used for geotechnical in-situ tests. It drives the standard specification penetrometer into the soil at the bottom of the borehole to a predetermined depth by specifying the hammer kinetic energy, and measures and records the corresponding standard penetration number. This number of hits can be used to determine the compactness of sand or the consistency of clay, and then determine the allowable bearing capacity of the foundation soil, evaluate the vibration liquefaction potential of sand, estimate the bearing capacity of a single pile, and determine the soil layer profile. At the same time, disturbed soil samples can also be taken out for general physical tests.

[0003] The existing standard penetrator is difficult to disassemble and clean due to the tight connection between the penetrator body and the soil, especially clay soil. After the standard penetration test, after all the threaded connections are released, there are two common methods: 1. Loosen the connection between the penetrator body and the soil by knocking multiple times to separate the two semicircular tubes; 2. Pry open with a screwdriver or other tools. These two methods may cause wear of the penetrator body after a period of use. At the same time, the existing penetrator pipe shoe is an integral whole. After the standard penetration test, the soil in the pipe shoe also needs to be knocked multiple times or cleaned out with a screwdriver or other tools, which also has the problem of pipe shoe wear and difficulty in cleaning.

[0021] The following is a further detailed description of the implementation of the utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Combination Figure 1 , Figure 2 and Figure 3 As shown, a standard penetrator that is easy to clean includes a head 1, a body 2 and a tube boot 3 that are connected in sequence from top to bottom. The head 1, the body 2 and the tube boot 3 are all connected by threaded joints. The body 2 and the tube boot 3 are both formed by splicing two semicircular tubes. The connection between the semicircular tubes of the tube boot 3 is respectively provided with a block 4 and a slot 5 that can be connected to each other. Specifically, this standard penetrator that is easy to clean is very cleverly designed. It uses a threaded joint connection to connect the head 1, the body 2 and the tube boot 3 together. Not only is the structure stable, but also it is easy to disassemble, which is conducive to cleaning and maintenance. At the same time, the body 2 and the tube boot 3 are designed to be spliced ​​by two semicircular tubes, so that it is more flexible in use, and the shape can be adjusted or disassembled for cleaning according to actual needs. In particular, the block 4 and the slot 5 that can be connected to each other are provided at the connection of the semicircular tubes of the tube boot 3. This design not only enhances the structural stability of the tube boot 3, but also ensures that it is not easy to fall off during use, thereby improving work efficiency and safety. In general, this standard penetrator is reasonably designed, easy to clean, and has high practical value. During use, the connection of each component can be checked regularly, and the accumulated impurities can be cleaned in time to ensure its normal operation and extend its service life. At the same time, key components such as the block 4 and the slot 5 can also be lubricated and maintained regularly to ensure their smooth operation. In addition, this design also embodies the concept of modularity and detachability, making the standard penetrator more convenient when repairing and replacing parts. If a component needs to be replaced, you only need to disassemble the corresponding threaded connection and then replace the new component without replacing the entire component, which reduces maintenance costs and time costs.

[0023] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the block 4 can be connected with the slot 5 by pushing and pulling up and down. Specifically, in the design of the standard penetrator, the block 4 is connected with the slot 5 by pushing and pulling up and down, and this design feature further enhances its convenience and flexibility in use. Specifically, by pushing and pulling up and down, the block 4 can be easily connected with the slot 5 without using complex tools or performing cumbersome operations. This design not only simplifies the installation and disassembly process, but also improves work efficiency. In addition, this connection method also has good stability and reliability. The block 4 and the slot 5 are tightly matched, which can effectively prevent the situation of falling off or loosening during use, and ensure the overall structural stability and working safety of the standard penetrator. It should be noted that when using this connection method, the block 4 and the slot 5 should be kept clean and lubricated to avoid poor connection or damage caused by impurities or friction. At the same time, it should be handled with care during operation to avoid excessive force causing damage to the components. In general, the design of the block 4 being connected with the slot 5 by pushing and pulling up and down makes this easy-to-clean standard penetrator more convenient, efficient and safe during use. This design not only improves work efficiency, but also reduces maintenance costs and has high practical value.

[0024] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a blocking block 51 is provided at the bottom of the slot 5, and when the blocking block 4 and the blocking block 51 conflict with each other, the top and bottom of the tube boot 3 are flush with each other. Specifically, in the design of the standard penetrator, the blocking block 51 provided at the bottom of the slot 5 is a clever detail, which ensures that when the blocking block 4 and the slot 5 are in place, the top and bottom of the tube boot 3 can be flush with each other. Specifically, when the blocking block 4 is connected with the slot 5 by pushing and pulling up and down, the blocking block 4 will gradually penetrate into the slot 5. When the blocking block 4 and the blocking block 51 conflict with each other, it means that the blocking block 4 has reached the predetermined position, at which time the two semicircular tubes of the tube boot 3 will be completely spliced ​​together, and the top and bottom are flush with each other. The advantage of this design is that it provides a clear indication to the user that the tube boot 3 has been installed in place. This not only ensures the stability and safety of the tube boot 3 during use, but also avoids performance degradation or damage caused by improper installation. In addition, the existence of the blocking block 51 also increases the structural strength of the card slot 5, so that the card slot 5 can better withstand the pressure and impact from the device tube shoe 3. This helps to extend the service life of the standard penetrator and improve the overall working performance. In general, the blocking block 51 set at the bottom of the card slot 5 is a practical and effective design element, which ensures the correct installation and stable operation of the device tube shoe 3 and improves the overall performance and reliability of the standard penetrator.

[0025] Combination Figure 3 , Figure 4 and Figure 5 As shown, the joints of the semicircular tubes of the body 2 are respectively provided with a protrusion 6 and a groove 7. Specifically, in the design of the standard penetrator, the protrusion 6 and the groove 7 provided at the joints of the semicircular tubes of the body further enhance the stability and overall performance of the body. Specifically, the design of the protrusion 6 and the groove 7 enables the two semicircular tubes of the body to be more closely combined when spliced. The protrusion 6 can be inserted into the groove 7 to form an interlocking structure, thereby effectively preventing the body 2 from loosening or separating during use. This design not only improves the stability of the body 2, but also helps to maintain the shape and structural stability of the body 2. When penetrating soil or other media, the body 2 needs to withstand a certain amount of pressure and impact, and the design of the protrusion 6 and the groove 7 can better disperse these forces and reduce the risk of deformation or damage to the body 2. In addition, the setting of the protrusion 6 and the groove 7 also makes the disassembly and assembly of the body 2 more convenient. When cleaning or replacing parts, it is only necessary to align the protrusion 6 and the groove 7, and then gently push or rotate to achieve the rapid disassembly and assembly of the body 2. In general, the protrusion 6 and the groove 7 provided at the joint of the semicircular tube of the body 2 are a practical and effective design, which enhances the stability and overall performance of the body 2 and improves the working efficiency and reliability of the standard penetrator. This design makes the standard penetrator have a wider application prospect in the fields of soil testing, geological exploration, etc.

[0026] Combination Figure 3 , Figure 4 and Figure 5As shown, the two ends of the body 2 are provided with extension rods 21, and the extension rods 21 are provided with external threads, and the lower end of the body 2 is provided with a pull ring 22. Specifically, in the design of the body 2, the addition of the extension rods 21 and the pull ring 22 at both ends not only enhances its functionality, but also improves the convenience of use. First, the provision of the extension rod 21 allows the body 2 to be more flexibly connected with other equipment or tools. Since the extension rods 21 are provided with external threads, it means that it can be screwed with a component with a corresponding internal thread to form a whole. This design allows the standard penetrometer to be used in conjunction with a variety of different equipment, expands its application range, and improves work efficiency. Secondly, the pull ring 22 at the lower end of the body 2 is very practical. When the penetrometer needs to be cleaned, the closed body 2 may need to apply a certain pulling force to separate. The pull ring 22 provides a convenient force application point, and the user can easily operate the body 2 through the pull ring 22, reducing the difficulty and complexity of the operation. At the same time, the pull ring 22 also enhances the stability of the instrument body and helps to maintain its stable position during work. In summary, the design of the extension rods 21 at both ends of the instrument body 2 and the pull ring 22 at the lower end greatly enhances the practicality and convenience of the standard penetrator. These designs not only improve work efficiency, but also make the standard penetrator more adaptable to various working environments and scenarios.

[0027] Combination Figure 3 , Figure 4 and Figure 5As shown, an extension tube 31 is provided at the top of the tube boot 3. When the tube boot 3 and the body 2 are spliced, the extension tube 31 is sleeved on the outer periphery of the pull ring 22, and the tube boot 3 and the body 2 form a seamless tube. Specifically, in the design of the standard penetrator, the extension tube 31 at the top of the tube boot 3 is a very clever and practical design element. When the tube boot 3 and the body 2 are spliced, the extension tube 31 is sleeved on the outer periphery of the pull ring 22, so that the tube boot 3 and the body 2 form a seamless tube. This design not only enhances the structural stability of the entire penetrator, but also improves its working performance and durability. Specifically, the design of the extension tube 31 helps to achieve a smooth transition between the tube boot 3 and the body 2. Since the extension tube 31 is sleeved on the outer periphery of the pull ring 22, when the two are spliced, a continuous, seamless tubular structure can be formed, avoiding the risk of performance degradation or damage caused by the unevenness of the connection. This seamless tube design helps to reduce the resistance that may occur during the penetration process, making the penetration operation smoother and more efficient. In addition, the extension tube 31 also plays a role in enhancing the structural strength. It can connect the tube boot 3 and the body 2 more closely together to form a whole, thereby improving the structural stability of the entire penetrator. This helps to reduce the loosening or deformation that may occur during the penetration process and prolong the service life of the penetrator. In summary, the design of the extension tube 31 on the top of the tube boot 3 is a practical and ingenious design element. It enables the tube boot 3 and the body 2 to form a seamless tube, improving the structural stability and working performance of the entire penetrator. This design not only improves work efficiency, but also reduces maintenance costs, providing strong support for work in the fields of geological exploration and soil testing.

[0028] Combination Figure 1 and Figure 2 As shown, the bottom of the head 1 is provided with an internal thread, and the head 1 is fixedly connected to the body 2 by a thread. Specifically, in the design of the standard penetrator, the threaded fixed connection between the internal thread at the bottom of the head 1 and the body 2 is a very practical and reliable connection method. This connection method not only enables the head 1 and the body 2 to be tightly connected together to form a whole, but also ensures the stability and reliability of the connection. By rotating the head 1, it can be easily connected or disassembled with the body 2. The operation process is simple and fast, and no additional tools or equipment are required. In addition, the threaded connection also has good sealing performance, which can effectively prevent liquid or impurities from entering the connection during use, thereby ensuring the normal operation and service life of the standard penetrator. In general, the threaded fixed connection between the internal thread at the bottom of the head 1 and the body is a very practical and effective design, which improves the overall performance and reliability of the standard penetrator, making it more widely and reliably used in geological exploration, soil testing and other fields. At the same time, this connection method is also convenient for maintenance and replacement of parts, and improves the maintenance efficiency of the equipment.

[0029] Combination Figure 1 and Figure 2 As shown, the head 1, body 2 and tube shoe 3 are all made of metal. Specifically, the use of metal materials to manufacture the head 1, body 2 and tube shoe 3 of the standard penetrometer is a practical and durable choice. Metal materials have high strength, high hardness and good wear resistance, which can ensure that the standard penetrometer works stably in complex geological environments and is not easily damaged. Specifically, metal materials can withstand greater pressure and impact force, so that the standard penetrometer is not easy to deform or break when penetrating soil or other media. At the same time, metal materials also have good corrosion resistance and can be used for a long time in a humid or chemical-containing environment without being corroded. In addition, metal materials also have high thermal conductivity and electrical conductivity, which helps to perform operations such as heat treatment or electrical measurement when necessary. At the same time, metal materials are relatively easy to process and manufacture, and can meet the needs of standard penetrometers of different specifications and sizes. In summary, metal materials are ideal for manufacturing the head 1, body 2 and tube shoe 3 of the standard penetrometer. It can not only ensure the strength and durability of the standard penetrometer, but also meet various working environments and testing requirements.
