Description

Technical Field

[0001] The invention relates to the technical field of geological sampling, and in particular to a water conservancy and environmental geology detection sampling device. Background Art

[0002] Water conservancy and environmental geological testing is one of the important technologies in the field of environmental protection. It can understand the pollution of groundwater by collecting samples and provide a scientific basis for environmental protection decisions. However, there are some problems with traditional sampling methods, such as the soil taken out is not easy to fall, not thorough, and it is inconvenient to clean the insertion tube. These problems affect the efficiency and accuracy of sampling and may lead to inaccurate and incomplete data.

[0003] The traditional sampling method usually uses a sampling tube to directly insert into the soil, and then take the soil out of the tube. The disadvantage of this method is that due to the large friction between soil particles, soil particles often do not fall out of the tube individually. This makes it difficult to pour out all the soil in the sampling tube after taking the soil, and the limited space in the sampling tube leads to limited space for operation when pouring the soil, resulting in incomplete and incomplete soil collection. And sometimes due to the adhesion of soil particles, when taking out some soils with higher viscosity or thinner soils, sometimes tools are needed to take out the soil. These factors have reduced the efficiency of traditional sampling methods.

[0004] In addition, the traditional sampling method also has the problem of inconvenient cleaning and disinfection of the insertion tube. When soil or other contaminants remain in the tube, it needs to be cleaned and disinfected to ensure the accuracy and reliability of subsequent experiments. However, traditional cleaning and disinfection methods often require manual operation, which is time-consuming and laborious, and the cleaning angle and space are limited, which will result in incomplete cleaning of the sampling device, thereby affecting the accuracy of subsequent soil sampling measurements.

[0005] Therefore, it is an urgent need to develop a new type of water conservancy and environmental geological detection sampling equipment. Such equipment can solve the problems of soil particles being difficult to remove, incomplete, and inconvenient to clean and disinfect in traditional sampling methods. Summary of the invention

[0006] In view of the problems in the prior art that soil particles are difficult to remove and not thorough in traditional sampling methods, and are inconvenient to clean and disinfect, a water conservancy and environmental geological detection sampling device is proposed.

[0007] The purpose is to unfold the bottom of the soil after taking out the soil, so as to facilitate the complete taking out of the soil and the cleaning of the soil.

[0008] The technical solution of the present invention is a water conservancy and environmental geology detection sampling device, comprising a soil taking component and a soil dropping component arranged in the soil taking component;

[0009] The soil taking component comprises a pushing component, an inserting component arranged at the bottom of the pushing component, and a limiting component arranged at the top of the inserting component;

[0010] The pushing assembly includes a pushing rod, a pushing block arranged at the bottom of the pushing rod, a pushing ring sleeved on the pushing block, a rotating sleeve arranged at the bottom of the pushing ring, a pushing cover sleeved on the pushing ring, and the pushing ring is slidably connected to the pushing block and the pushing cover respectively, pushing columns symmetrically arranged on both sides of the bottom of the inner wall of the pushing cover, and pushing holes opened on both sides of the pushing ring;

[0011] The soil taking component is used for inserting into the soil to take soil, and the soil dropping component is used for making the taken soil fall.

[0012] By adopting the above technical scheme, the sampling device is inserted into the soil through the set soil taking component, and then the soil taken out is automatically dropped under the action of gravity through the soil dropping component, so as to achieve the effect of automatic soil dropping after soil taking. When taking soil, the insertion component is inserted into the soil through the pushing component to take soil. When pushing, one hand holds the rotating sleeve and the other hand holds the rotating rod. The pushing rod is rotated so that the pushing rod drives the pushing cover and the pushing block to rotate, so that the two pushing columns at the bottom of the pushing cover rotate and abut against the pushing hole. At this time, when taking soil, when the pushing rod is pressed downward, the pushing cover will drive the pushing ring to squeeze the insertion component, so that the insertion component enters the soil for soil taking operation.

[0013] Furthermore, the insertion component includes an insertion sheet arranged in a ring array at the bottom of the push ring, an extrusion block arranged at the top of the insertion sheet, a rotating hole opened in a ring array at the bottom of the push ring, and the top of the insertion sheet is rotatably connected to the rotating hole, abutment grooves symmetrically opened on both sides of the top of the insertion sheet, a fixing column arranged in the abutment groove, and one side of the fixing column is fixedly connected to the side wall of the rotating hole, and a torsion spring arranged between the abutment groove and the fixing column.

[0014] By adopting the above technical scheme, when inserting to take soil, the insertion piece will be inserted into the soil, and the squeezing block is set for the subsequent insertion piece to be squeezed and then rotated to open. When the soil falls subsequently, the squeezing block is squeezed, so that the squeezing block rotates in the axial direction of the pushing ring, thereby driving the insertion piece to rotate synchronously, so that the soil in the middle of the insertion piece is exposed and automatically falls. The torsion spring set between the abutment groove and the fixed column is used for resetting the insertion piece after the soil falls and is unfolded. When the insertion piece is in the initial state, the torsion spring abuts between the abutment groove and the fixed column, so that the insertion piece is in a vertical state. When the insertion piece is squeezed and rotated, the torsion spring is twisted. When the squeezing block is not squeezed, the insertion piece returns to the vertical state under the resetting action of the torsion spring. The torsion spring has a twisting and resetting effect, which is a prior art and is not drawn in the figure.

[0015] Furthermore, an insertion slope is provided on the inner side of the bottom of the inserting piece, and a plurality of annular strips are arranged in a linear array on the inner side of the inserting piece, and the bottom of the inserting piece is pointed.

[0016] By adopting the above technical solution, the setting of the pointed end and the insertion slope at the bottom of the insertion piece allows the insertion piece to be inserted into the soil more quickly, and the setting of several annular strips can increase the friction and resistance of the insertion piece to the soil when it is pulled out, thereby achieving smooth removal of the soil.

[0017] Furthermore, the top of the push cover is provided with through holes in a ring array.

[0018] By adopting the above technical solution, when inserting and taking soil, the push rod is pressed down so that the push cover presses down the push ring and the insertion piece to be inserted into the soil. During the insertion process, when the soil enters the push ring, the side wall of the push ring and the entered soil form a closed state, making it difficult for the push rod to be pushed. The design of the through hole prevents the insertion piece from forming a closed cavity inside the push ring during the insertion process, which facilitates the insertion of the insertion piece when taking soil and increases the insertion speed.

[0019] Furthermore, the limiting assembly includes a limiting groove opened on one side of the extrusion block, a limiting block arranged on one side of the limiting member, and a rotating surface opened on one side of the bottom of the limiting block, and one end of the limiting block is clamped with the inside of the push ring.

[0020] By adopting the above technical scheme, the setting of the limit assembly is used to ensure that the insertion piece is inserted into the soil in a vertical downward posture when inserted into the soil to take soil, so as to prevent the insertion piece from rotating to both sides during the insertion process of the soil, thereby causing failure of soil taking and improving the stability of the insertion during soil taking. During the insertion process, one end of the limit block is engaged with the limit groove, so that the insertion piece does not rotate and always maintains a vertical state. The limit piece can be a spring. When the extrusion block is squeezed, the limit block will be pushed to shrink into the limit groove. At this time, the limit piece is compressed. When the extrusion block is not squeezed, the insertion piece rotates to a vertical state under the resetting action of the torsion spring. At this time, when the limit block is driven to rotate by the extrusion block, the rotating surface and the inner side edge of the bottom of the push ring squeeze each other, so that the limit block will be re-engaged in the limit groove under the resetting action of the limit piece, which is convenient for insertion during the next soil taking.

[0021] Furthermore, the soil-falling component includes an extrusion component arranged inside the push ring, and a reset component sleeved on the extrusion component;

[0022] The extrusion assembly includes a rotating groove opened inside the push ring, an extrusion ring arranged in the rotating groove and rotatably connected to the rotating groove, extrusion holes opened on both sides of the extrusion ring, a movable hole opened on the push ring and connected to the push hole, and two ends of the push column are respectively slidably connected to the movable hole and the extrusion hole, one side of the limit block is clamped with the bottom of the rotating groove, a rotating block is arranged in a ring array at the bottom of the extrusion ring, and the rotating block is rotatably connected to the rotating cavity, and an extrusion surface is opened on the side of the extrusion block away from the center position of the push ring.

[0023] When the lever is lifted up, the cam is released, and the lever is held in place with the other hand to allow the lever to be moved back to the top of the lever, and the lever is then released to allow the lever to be moved back to the top of the lever, and the lever is then released to the top of the lever, and the lever is then released to the bottom of the lever.

[0024] Furthermore, the reset assembly includes a limit plate arranged at the bottom of the rotating groove, and the bottom of the extrusion ring is clamped and rotatably connected to the limit plate, a reset member arranged at the top of the limit plate, and a reset plate arranged at the top of the reset member, and the top of the reset plate abuts against the bottom of the push column.

[0025] By adopting the above technical solution, when the pushing column moves to the bottom of the moving hole, the rotating block and one side of the extrusion block are in an extrusion state. When the pushing rod is rotated to make the pushing cover drive the pushing column to move in the locking hole and move to the end of the locking hole, the rotating block has not yet escaped from the extrusion state with the extrusion block, so that when the pushing rod is reset and rotated to drive the pushing column back to the end of the moving hole, one side of the rotating block can also be rotated and reset along the original path of the extrusion surface to avoid the rotating block being separated from the extrusion surface during the rotation process and causing the rotating block to be unable to reset. When the pushing column moves to the bottom of the moving hole, under the reset action of the reset member, the reset member can be a spring, and the reset member pushes the reset plate upward, and the pushing column is pushed upward by the reset plate in the moving hole, so that the extrusion ring rotates and resets, and the insertion piece also rotates and resets to a vertical state.

[0026] Furthermore, a locking hole connected to the moving hole is provided at the bottom of the pushing ring, and the locking hole and the pushing hole are in a horizontal state, and the moving hole is in a vertical state.

[0027] By adopting the above technical solution, the setting of the locking holes allows several insertion pieces to always remain in the expanded state. Firstly, it is convenient to clean the soil that has not completely fallen out of the insertion piece. Secondly, it is convenient to clean the device after the soil falls. The soil in the corners of the device can be cleaned, thereby improving the cleaning efficiency and enhancing the cleaning effect.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The expandable insert sheet allows the soil to fall down under its own weight after the insert sheet is expanded. The automatic soil dropping of the sampling sheet can complete the collection of multiple soil samples at one time, greatly improving the sampling efficiency. At the same time, it avoids the tedious process of frequently cleaning the sampling tube to reduce the mixing of external pollutants in the traditional sampling method.

[0030] 2. The setting of the locking hole allows several inserts to remain in the unfolded state. First, it is convenient to clean the soil that has not completely fallen out of the insert, and second, it is convenient to clean the device after the soil falls. The soil in the corners of the device can be cleaned, which improves the cleaning efficiency and enhances the cleaning effect. It is convenient to clean the sampling tube. Since the soil sample has been collected in the sampling piece, the sampling tube can be directly placed in the cleaning liquid for cleaning after the soil is taken out. There is no need for additional internal and external cleaning steps, which improves the cleaning efficiency and avoids the damage caused by repeated disassembly and assembly of the sampling tube in the traditional cleaning method.

[0031] 3. Reduced risk of injury to the operator. In traditional sampling methods, there may be larger particles or harder soil particles at the bottom of the sampling tube, which need to be removed manually, which may cause damage to the operator's fingers. This method avoids this risk and protects the operator's personal safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0044] Example 1, reference Figure 1-Figure 4 , which is the first embodiment of the present invention, provides a hydraulic environmental geological detection sampling equipment, including a soil taking component and a soil dropping component installed in the soil taking component; the soil taking component includes a pushing component 1, an inserting component 2 installed at the bottom of the pushing component 1, and a limiting component 3 installed at the top of the inserting component 2; the pushing component 1 includes a pushing rod 17, a pushing cover 14 fixedly connected to the bottom of the pushing rod 17, a pushing block 11 fixedly connected to the bottom of the pushing cover 14, a pushing ring 12 sleeved on the pushing block 11, and the pushing cover 14 is sleeved on the pushing ring 12, a rotating sleeve 13 fixedly connected to the bottom of the pushing ring 12, and the pushing ring 12 is respectively slidably connected to the pushing block 11 and the pushing cover 14, a pushing column 15 symmetrically fixedly connected to both sides of the bottom of the inner wall of the pushing cover 14, and a pushing hole 16 opened on both sides of the pushing ring 12; the soil taking component is used to be inserted into the soil to take soil, and the soil dropping component is used to make the taken soil fall.

[0045] Specifically, the sampling device is inserted into the soil through the provided soil taking component, and then the soil taken out is automatically dropped under the action of gravity through the soil dropping component, so as to achieve the effect of automatic soil dropping after soil taking. When taking soil, the insertion component 2 is inserted into the soil through the pushing component 1 to take soil. When pushing, one hand holds the rotating sleeve 13 and the other hand holds the rotating rod, and the pushing rod 17 is rotated so that the pushing rod 17 drives the pushing cover 14 and the pushing block 11 to rotate, so that the two pushing columns 15 at the bottom of the pushing cover 14 rotate and abut against the pushing hole 16. At this time, when taking soil, when the pushing rod 17 is pressed downward, the pushing cover 14 will drive the pushing ring 12 to squeeze the insertion component 2, so that the insertion component 2 enters the soil to take soil.

[0046] Reference Figure 1-Figure 5 The insertion component 2 includes an insertion piece 21 rotatably connected to the bottom of the push ring 12 in an annular array, an extrusion block 22 fixedly connected to the top of the insertion piece 21, a rotation hole 23 arranged in an annular array at the bottom of the push ring 12, and the top of the insertion piece 21 is rotatably connected to the rotation hole 23, abutment grooves 24 symmetrically arranged on both sides of the top of the insertion piece 21, a fixed column 25 rotatably connected in the abutment groove 24, and one side of the fixed column 25 is fixedly connected to the side wall of the rotation hole 23, and a torsion spring abutting between the abutment groove 24 and the fixed column 25.

[0047] Specifically, when inserting to take soil, the insertion piece 21 will be inserted into the soil, and the squeezing block 22 is set for the subsequent insertion piece 21 to be squeezed and rotated to open. When the soil falls subsequently, the squeezing block 22 is squeezed, so that the squeezing block 22 rotates toward the axial direction of the push ring 12, thereby driving the insertion piece 21 to rotate synchronously, so that the soil in the middle of the insertion piece 21 is exposed and automatically falls. The torsion spring set between the abutment groove 24 and the fixed column 25 is used for resetting the insertion piece 21 after the soil falls and is unfolded. When the insertion piece 21 is in the initial state, the torsion spring abuts between the abutment groove 24 and the fixed column 25, so that the insertion piece 21 is in a vertical state. When the insertion piece 21 is squeezed and rotated, the torsion spring is twisted. When the squeezing block 22 is not squeezed, the insertion piece 21 returns to the vertical state under the resetting action of the torsion spring. The torsion spring has a twisting and resetting effect, which is a prior art and is not drawn in the figure.

[0048] Reference Figure 1-Figure 5 The inner side of the bottom of the insert piece 21 is provided with an insert slope 26 and a plurality of annular strips 27 fixedly connected to the inner side of the insert piece 21 in a linear array, and the bottom of the insert piece 21 is pointed.

[0049] Specifically, the tip at the bottom of the insert piece 21 and the insertion slope 26 enable the insert piece 21 to be inserted into the soil more quickly, and the provision of the plurality of annular strips 27 can increase the friction and resistance of the insert piece 21 to the soil when it is pulled out, thereby achieving smooth removal of the soil.

[0050] Reference Figure 2 The top of the push cover 14 is provided with through holes 28 in a circular array.

[0051] Specifically, when inserting to take soil, the push rod 17 is pressed down so that the push cover 14 presses down the push ring 12 and the insertion piece 21 to be inserted into the soil. During the insertion process, when the soil enters the push ring 12, the side wall of the push ring 12 and the entered soil form a closed state, making it difficult for the push rod 17 to be pushed. The design of the through hole 28 prevents the insertion piece 21 from forming a closed cavity inside the push ring 12 during the insertion process, thereby facilitating the insertion of the insertion piece 21 when taking soil and increasing the insertion speed.

[0052] Example 2, reference Figure 1-Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the limiting assembly 3 includes a limiting groove 31 opened on one side of the extrusion block 22, a limiting block 33 fixedly connected to one side of the limiting member 32, and a rotating surface 34 opened on one side of the bottom of the limiting block 33, and one end of the limiting block 33 is clamped with the inside of the push ring 12.

[0053] Specifically, the setting of the limiting assembly 3 is used to ensure that the inserting piece 21 is inserted into the soil in a vertical downward posture when inserted into the soil, so as to prevent the inserting piece 21 from rotating to both sides during the insertion process, thereby causing failure of soil extraction, and improve the stability of soil extraction insertion. During the insertion process, one end of the limiting block 33 is engaged with the limiting groove 31, so that the inserting piece 21 does not rotate and always maintains a vertical state. The limiting member 32 can be a spring. When the extrusion block 22 is squeezed, the limiting block 33 will be pushed to shrink into the limiting groove 31. At this time, the limiting member 32 is compressed. When the extrusion block 22 is not squeezed, the inserting piece 21 rotates to a vertical state under the reset action of the torsion spring. At this time, when the limiting block 33 is driven to rotate by the extrusion block 22, the rotating surface 34 and the inner side of the bottom of the pushing ring 12 are mutually squeezed, so that the limiting block 33 will be re-engaged in the limiting groove 31 under the reset action of the limiting member 32, which is convenient for insertion during the next soil extraction. The rest of the structure is the same as that of Example 1.

[0054] Example 3, reference Figure 1-Figure 8, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the soil-falling component includes an extrusion assembly 4 installed inside the push ring 12, and a reset assembly 5 sleeved on the extrusion assembly 4; the extrusion assembly 4 includes a rotating groove 41 opened inside the push ring 12, an extrusion ring 42 rotatably connected to the rotating groove 41, extrusion holes 43 opened on both sides of the extrusion ring 42, a moving hole 44 opened on the push ring 12 and connected to the push hole 16, and the two ends of the push column 15 are respectively slidably connected to the moving hole 44 and the extrusion hole 43, one side of the limit block 33 is clamped with the bottom of the rotating groove 41, a rotating block 45 is fixedly connected to the bottom of the extrusion ring 42 in an annular array, and the rotating block 45 is rotatably connected to the rotating cavity, and an extrusion surface 46 is opened on the side of the extrusion block 22 away from the center position of the push ring 12.

[0055] Specifically, after the insertion component 2 is pulled out, one hand holds the rotating sleeve 13, and the other hand rotates the push rod 17, so that the push column 15 can be rotated to the top of the moving hole 44, and then the push rod 17 is pressed down so that the push cover 14 drives the push columns 15 on both sides to compress the reset component 5 in the moving hole 44. Since the limiting plate 51 in the reset component 5 limits the extrusion ring 42, the extrusion ring 42 cannot move downward with the push column 15 when being pressed down by the push column 15. Therefore, the push column 15 moves downward in the moving hole 44 and moves in the extrusion hole 43 at the same time. The extrusion hole 43 is arc-shaped, so that the extrusion ring 42 drives the bottom rotating block 45 in the rotating groove 41. The rotation causes the rotating block 45 to squeeze the limit block 33, unlocking the clamping and limiting effect of the limit block 33 on the squeezing block 22. At this time, one side of the rotating block 45 squeezes the squeezing surface 46, and the squeezing surface 46 is also arc-shaped, so that the squeezing block 22 drives the insertion piece 21 to rotate around the fixed column 25 toward the center of the push ring 12, that is, several insertion pieces 21 are unfolded synchronously, so that the soil in the insertion piece 21 falls under the action of its own weight. By using the automatic soil falling method of the sampling piece, multiple soil samples can be collected at one time, which greatly improves the sampling efficiency. At the same time, it avoids the tedious process of frequently cleaning the sampling tube to reduce the mixing of external pollutants in the traditional sampling method.

[0056] Reference Figure 1-Figure 9 The reset assembly 5 includes a limit plate 51 fixedly connected to the bottom of the rotating groove 41, and the bottom of the extrusion ring 42 is clamped and rotatably connected to the limit plate 51, a reset member 52 fixedly connected to the top of the limit plate 51, and a reset plate 53 fixedly connected to the top of the reset member 52, and the top of the reset plate 53 abuts against the bottom of the push column 15.

[0057] Specifically, when the pushing column 15 moves to the bottom of the moving hole 44, the rotating block 45 and one side of the extrusion block 22 are in an extrusion state. When the pushing rod 17 is rotated to make the pushing cover 14 drive the pushing column 15 to move in the locking hole 6, and move to the end of the locking hole 6, the rotating block 45 is still not separated from the extrusion state with the extrusion block 22, so that when the pushing rod 17 is reset and rotated to drive the pushing column 15 to return to the end of the moving hole 44, one side of the rotating block 45 can also be rotated and reset along the original extrusion surface 46 to avoid the rotating block 45 being separated from the extrusion surface 46 during the rotation process, causing the rotating block 45 to be unable to reset. When the pushing column 15 moves to the bottom of the moving hole 44, under the reset action of the reset member 52, the reset member 52 can be a spring, and the reset member 52 pushes the reset plate 53 upward, and the pushing column 15 is pushed upward by the reset plate 53 in the moving hole 44, so that the extrusion ring 42 is rotated and reset, and the insertion piece 21 is also rotated and reset to a vertical state.

[0058] Reference Figure 1-Figure 9 A locking hole 6 connected to the moving hole 44 is provided at the bottom of the pushing ring 12, and the locking hole 6 and the pushing hole 16 are in a horizontal state, and the moving hole 44 is in a vertical state.

[0059] Specifically, the setting of the locking hole 6 allows the several inserting pieces 21 to be kept in the unfolded state. First, it is convenient to clean the soil that has not completely fallen out of the inserting piece 21. Second, it is convenient to clean the device after the soil falls. The soil in the corners of the device can be cleaned, which improves the cleaning efficiency and enhances the cleaning effect. It is convenient to clean the sampling tube. Since the soil sample has been collected in the sampling piece, the sampling tube can be directly put into the cleaning liquid for cleaning after the soil is taken out. There is no need to perform additional internal and external cleaning steps, which improves the cleaning efficiency and avoids the damage caused by repeated disassembly and assembly of the sampling tube in the traditional cleaning method. The rest of the structure is the same as that of Example 2.

[0060] The working principle of the present invention is as follows: when taking soil, the push rod 17 is rotated so that the push cover 14 drives the push column 15 to rotate and snap into the push hole 16, and the push rod 17 is pressed down so that the push column 15 presses the push ring 12 and the insertion piece 21 to insert into the soil, and the friction force is increased by the annular strip 27 provided on the insertion piece 21, so as to bring out the soil in the insertion piece 21. After taking out, the push rod 17 is reversely rotated and pressed down so that the push cover 14 drives the push column 15 to move downward. In the process of the push column 15 being driven to move downward, the push column 15 moves in the extrusion hole 43. Since the extrusion ring 42 is limited, it can only rotate in the horizontal direction, so that the extrusion ring 42 drives the rotating block 45 at the bottom to rotate. One side of the rotating block 45 squeezes the limit block 33, unlocks the limit of the limit block 33 on the insertion piece 21, and moves along the extrusion surface 46, so that the extrusion block 22 drives the insertion piece 21 to rotate, thereby making the insertion piece 21 unfold. After unfolding, the push rod 17 is rotated again to make the push cover 14 drive the push column 15 to move in the locking hole 6, so that the reset member 52 pushes the push column 15 upward through the limit plate 51, so that the push column 15 is abutted in the locking hole 6, so as to keep the insertion piece 21 in a continuously unfolded state, which is convenient for cleaning the soil that has not fallen yet and cleaning the insertion piece 21 and the push ring 12 after the soil has fallen, thereby improving the cleanliness of the device and thus improving its service life.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
