Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction, and in particular to a soil sampling device for water conservancy construction. Background Technology

[0002] Water conservancy construction is a complex and highly systematic engineering activity. The construction process includes engineering surveying, which involves a detailed understanding of the topography, geology, hydrology, soil and other conditions of the construction site. For example, geological samples are obtained through drilling, and information such as groundwater level and soil structure is analyzed to provide a basis for subsequent design and construction.

[0003] When taking soil samples, construction workers usually place the sampler at the sampling site, then insert the sampling head into the soil, and bring the soil out through the sampling head. Then, they dig out the soil sample by tapping the sampling head or by inserting a tool into the sampling head. Finally, the soil sample is preserved and tested.

[0004] The existing technology has the following drawbacks: some existing equipment extracts soil samples in lumps or powder by tapping the sampling head and digging with tools, making it difficult to ensure the integrity of the soil. In addition, when the sampling site is uneven, it cannot be guaranteed that the sampling head can be inserted vertically into the ground. It is necessary to manually lay additional supports at the bottom of the device to keep it level, which is time-consuming and labor-intensive. Therefore, a soil sampling device for water conservancy construction is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a soil sampling device for water conservancy construction, which aims to improve the problem that the existing technology cannot guarantee the integrity of the soil sample taken out.

[0033] 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.

[0034] Reference Figures 1-3This utility model provides an embodiment of a soil sampling device for water conservancy construction, including a support 1. Rollers and a handle are provided at the bottom of the support 1. The rollers and handle work together to move the device to the sampling location. A connecting rod 12 is fixedly connected to the inner wall of the support 1. Two sets of connecting rods 12 are provided, and the two sets of connecting rods 12 provide connection and support for the ball sleeve 9. An adjustment component is provided on the outer wall of the connecting rod 12. A telescopic rod 2 is fixedly connected to the bottom of the adjustment component. The electric telescopic rod 2 is a device that converts the rotational motion of an electric motor into linear telescopic motion. When the motor receives a start signal, it begins to rotate, driving the sleeve in the telescopic rod 2 to move relative to the motor via a transmission mechanism. If the motor rotates forward, the telescopic rod 2 extends; if the motor rotates in reverse, the telescopic rod 2 retracts. This is prior art and will not be elaborated further. A round cover 3 is fixedly connected to the bottom of the telescopic rod 2. The bottom of the cover 3 contacts a sampling head 8, which is made of stainless steel. Stainless steel has high strength and can withstand greater pressure, making it suitable for use in soft soil or in situations requiring deep sampling. A tube sleeve 7 is inserted into the outer wall of the sampling head 8. The inner wall of the round cover 3 is provided with a limiting mechanism, which includes a lever 4. There are two sets of levers 4, which are elastically connected by a movable spring 5. When the two sets of levers 4 come close to each other, the movable spring 5 is compressed. When resetting, the elastic force of the movable spring 5 is used to reset the two sets of levers 4. The inner wall of the lever 4 is slidably connected to a guide post 6, which guides the lever 4 and allows it to move laterally. The lever 4 is slidably connected to the inner wall of the round cover 3. The inner wall of the round cover 3 has slots corresponding to the two sets of levers 4, allowing the levers 4 to move laterally.

[0035] Reference Figure 1 and Figure 6 The adjustment assembly includes a ball sleeve 9, with a rotating ball 10 rotatably connected to the inner wall of the ball sleeve 9. An electromagnet 11 is fixedly connected to the top of the ball sleeve 9. The electromagnet 11 utilizes the properties of an electromagnet. When current passes through the coil of the electromagnet, the electromagnet generates a strong magnetic field that can attract ferromagnetic materials, such as scrap iron and steel. This is existing technology and will not be elaborated further. The ball sleeve 9 is fixedly connected to the outer wall of the connecting rod 12. The middle part of the ball sleeve 9 is hollow. The interior of the ball sleeve 9 has enough space to allow the rotating ball 10 to rotate freely. The bottom end of the rotating ball 10 is fixedly connected to the top of the telescopic rod 2. The rotating ball 10 is made of metal material. When the electromagnet 11 is energized, it generates a magnetic field that attracts and positions the rotating ball 10.

[0036] Reference Figure 4 and Figure 5The push block 4 is inserted through and into the inner wall of the sleeve 7. The inner wall of the sleeve 7 has two sets of slots corresponding to the push block 4. The push block 4 is initially inserted into the slots of the sleeve 7. The outer wall of the round cover 3 is in contact with the inner wall of the sleeve 7. The sampling head 8 is arc-shaped. There are two sets of sampling heads 8. When the two sets of arc-shaped sampling heads 8 are closed, they can sample the soil.

[0037] Working Principle: When soil sampling is required, the operator first moves the device to the sampling location. During movement, the rotating ball 10 rotates within the ball sleeve 9. When the device is stationary, under its own gravity, the rotating ball 10, along with the telescopic rod 2, the tube sleeve 7, the lever 4, and the sampling head 8, remains perpendicular to the ground. Next, the external power supply connected to the electromagnetic motor 11 is turned on. The magnetic force generated by the electromagnetic motor 11 attracts the rotating ball 10, positioning the sampling head 8. The operator then electrically controls the telescopic rod 2, pushing the tube sleeve 7 and sampling head 8 into the soil. After sampling, the electrically controlled telescopic rod 2, along with the tube sleeve 7 and sampling head 8, rises. When the soil sample needs to be removed, the operator manually presses the two sets of levers 4. The levers 4 move closer together along the outer wall of the guide column 6, compressing the movable spring 5. When the levers 4 separate from the groove on the tube sleeve 7, the operator can retrieve the sample. Lower the sleeve 7, and simultaneously release the lever 4. The spring force of the movable spring 5 will cause the lever 4 to return to its initial state. Then, flip the sleeve 7, and the sampling head 8 will slide out of the sleeve 7. Separate the two sets of sampling heads 8 and take out the complete soil sample. When it is necessary to install the sampling head 8, put the two sets of sampling heads 8 together into the sleeve 7. The protrusion on the inner wall of the sleeve 7 will block the sampling head 8, completing the limitation of the sampling head 8 and preventing the sampling head 8 from falling off. Then, press the lever 4. The lever 4 will move closer to each other along the outer wall of the guide post 6 and squeeze the movable spring 5. The operator aligns the round cover 3 and inserts it into the sleeve 7. At this time, the groove of the sleeve 7 coincides with the lever 4. Release the lever 4, and the spring force of the movable spring 5 will cause the lever 4 to be inserted into the groove of the sleeve 7, completing the limitation of the sleeve 7. If it is necessary to sample the soil again, simply repeat the above operation steps.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
