Description

Technical Field

[0001] This utility model relates to the field of geotechnical exploration technology, and more specifically, to a fixing device for a sand sampler in hydrogeological geotechnical exploration. Background Technology

[0002] A sand sampler is a device used to sample sandy soil, silty soil, or general soil layers. When using a sand sampler, it is necessary to fix it in place to prevent the device from shifting due to vibration or ground pressure during sand sampling, thus ensuring its original state.

[0003] Patent CN211013609U discloses a fixing device for a sand sampler used in soil and rock exploration. When the ground at the sand sampling site is flat, the overall height of the adjusting mechanism is adjusted to the same level, and the entire adjusting mechanism is buried underground using a conical drill rod. It is then fixed by connecting it with expansion bolts and connecting holes. When the ground at the sand sampling site is sloping, the overall height of the adjusting mechanism is adjusted to match the slope of the ground, ensuring that the first connecting rod, the second connecting rod, and the ground are vertically aligned. However, when this fixing device is applied to sloping ground, its connecting blocks cannot contact the ground, and its lower base plate cannot effectively fix the entire device by utilizing the connecting blocks. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a fixing device for sand sampling tools in hydraulic engineering and geotechnical exploration.

[0005] A fixing device for a sand sampler in a hydraulic geotechnical exploration site includes an upper base plate and a lower base plate; the upper base plate and the lower base plate form an adjustable fixed connection, and the upper base plate and the lower base plate are provided with overlapping through holes at their centers; the lower base plate is also rotatably connected to an auxiliary base plate, which is arranged parallel to the lower base plate or at an acute angle.

[0006] The lower base plate is provided with a first through hole, and the auxiliary base plate is provided with a strip hole. The positioning pin passes through the first through hole and the strip hole distributed vertically and vertically and then enters the ground.

[0007] Connecting blocks are also provided on the side of the auxiliary base plate.

[0008] Furthermore, the lower base plate is fixedly connected to four connecting rods arranged circumferentially with the center of the through hole as the center, and the upper base plate is provided with a second through hole that matches the position of the connecting rods.

[0009] Furthermore, the outer wall of the top end of the connecting rod is threaded. After the connecting rod passes through the upper base plate, a first fixing nut is provided above the upper base plate and a second fixing nut is provided below the upper base plate, for adjusting and fixing the position of the upper base plate.

[0010] Furthermore, a first rotating sleeve is fixedly connected to the lower end face of the lower base plate, and a second rotating sleeve is fixedly connected to one side of the auxiliary base plate. The first rotating sleeve and the second rotating sleeve are arranged alternately. A through shaft passes through the first rotating sleeve and the second rotating sleeve to form a rotating connection between the lower base plate and the auxiliary base plate.

[0011] Furthermore, the through shaft is a long screw, and its end is limited by a nut.

[0012] Furthermore, the lower base plate is provided with first through holes at its four corners, and the auxiliary base plate has two strip holes located below the two first through holes on the same side; the auxiliary base plate also has a waist-shaped hole at its center, located below the through hole of the lower base plate.

[0013] Furthermore, four connecting blocks are fixed to the side of the auxiliary base plate. The connecting blocks have connecting holes for fixing to the ground. They can be fixed to flat ground or to sloping ground and fixed with anchor rods.

[0014] Furthermore, when used on sloping ground, a support structure is provided between the lower base plate and the auxiliary base plate.

[0016] Furthermore, a rubber gasket is engaged within the through hole.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This sand sampler fixing device for hydraulic engineering and geotechnical exploration is used for fixing the sand sampler on flat ground. The auxiliary base plate is parallel and fitted to the lower base plate. The positioning pin passes through the first through hole in the lower base plate and the slotted hole in the auxiliary base plate before entering the ground, achieving initial anchoring of the device. A secondary anchoring is achieved by using anchor rods passing through the connecting holes of the connecting blocks, further ensuring stable fixing of the device. When fixing the sand sampler on sloping ground, the auxiliary base plate rotates relative to the lower base plate around the through-axis until it matches the angle of inclination with the ground, forming an acute angle. Simultaneously, a support structure with a suitable height supports the lower base plate. At this point, the connecting blocks are tightly fitted to the sloping surface, and the anchor rods pass through the connecting holes, achieving overall fit and anchoring of the device to the sloping ground.

[0035] 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.

[0036] like Figures 1-5 As shown, this embodiment provides a fixing device for a sand sampler in hydraulic geotechnical exploration, including an upper base plate 1 and a lower base plate 2. The upper base plate 1 and the lower base plate 2 form an adjustable fixed connection. A through hole 3, overlapping vertically, is arranged at the center of the upper base plate 1 and the lower base plate 2, and a rubber washer 31 is engaged within the through hole 3. An auxiliary base plate 4 is also rotatably connected to the lower base plate 2. The auxiliary base plate 4 is arranged parallel to the lower base plate 2 or at an acute angle. When the auxiliary base plate 4 is parallel to the lower base plate 2, the device is suitable for use on a flat surface; when the auxiliary base plate 4 is at an acute angle to the lower base plate 2, the device is suitable for use on a sloping surface. The bottom plate 2 is provided with a first through hole 21, and the auxiliary bottom plate 4 is provided with a strip hole 41. The positioning pin 5 passes through the first through hole 21 and the strip hole 41 distributed vertically and then enters the ground. At the same time, a connecting block 6 is also provided on the side of the auxiliary bottom plate 4. An anchor rod is used to pass through the connecting block to further stabilize and fix the auxiliary bottom plate to the ground, thereby facilitating the use of the sand extractor.

[0037] In this embodiment, the lower base plate 2 is fixedly connected to four connecting rods 7 arranged circumferentially around the center of the through hole 3. The upper base plate 1 has a second through hole 11 that matches the position of the connecting rods 7. Threads 71 ​​are provided on the outer wall of the top end of the connecting rods 7. After the connecting rods 7 pass through the upper base plate 1, a first fixing nut 12 is provided above the upper base plate 1, and a second fixing nut 13 is provided below the upper base plate 1, for adjusting the position of the upper base plate 1, thereby allowing adjustment of the distance between the upper base plate 1 and the lower base plate 2.

[0038] To further facilitate the use of the sand extractor, rubber pads are provided between the first fixing nut 12 and the upper base plate 1, and between the second fixing nut 13 and the upper base plate 1, in practical applications. These rubber pads provide cushioning during the operation of the sand extractor. The upper base plate 1 is height-adjustable via the connecting rod 7, the first fixing nut 12, and the second fixing nut 13. The rubber washer 31 and the rubber pads work together to provide cushioning.

[0039] In this embodiment, three first rotating sleeves 22 are fixedly connected to the lower end face of the lower base plate 2, and two second rotating sleeves 42 are fixedly connected to one side of the auxiliary base plate 4. The first rotating sleeves 22 and the second rotating sleeves 42 are arranged alternately. The through shaft 8 passes through the first rotating sleeves 22 and the second rotating sleeves 42 to form a rotatable connection between the lower base plate 2 and the auxiliary base plate 4. The through shaft 8 is a long screw, and its end is limited by a nut.

[0040] The lower base plate 2 has four circular first through holes 21 at its four corners. The auxiliary base plate 4 has two strip holes 41 located below the two first through holes 21 on the same side. The auxiliary base plate 4 also has a waist-shaped hole 43 located below the through hole 3 in the lower base plate 2. The structural design of the two strip holes 41 and the central waist-shaped hole 43 in the auxiliary base plate 4 ensures that when the auxiliary base plate 4 is tilted, the projections of the first through holes 21 and the central through hole 3 on the auxiliary base plate 4 should be within the corresponding strip holes 41 and waist-shaped holes 43. This allows the positioning pin 5 to penetrate the vertically distributed first through holes 21 and strip holes 41 and enter the ground, while the sand extractor can pass through the through hole 3 and waist-shaped hole 43 to collect samples.

[0041] In this embodiment, four connecting blocks 6 are fixed to the side of the auxiliary base plate 4. The connecting blocks 6 have connecting holes 61 for fixing to the ground. They can be fixed to flat ground or to sloping ground and are fixed with anchor rods.

[0042] When this device is used on a sloping surface, a support structure 9 is also provided between the lower base plate 2 and the auxiliary base plate 4. The support structure 9 includes an upper support plate 91, a lower support plate 92, and a support column 93. The two ends of the support column 93 are rotatably connected to the upper support plate 91 and the lower support plate 92, respectively. The lower support plate 93 has fixing holes 94 for fixing the ground. Specifically, the upper support plate 91 is provided with an upper connecting ear 911, the lower support plate 92 is provided with a lower connecting ear 921, and the two ends of the support column 93 are rotatably connected to the upper connecting ear 911 and the lower connecting ear 921, respectively.

[0043] In this embodiment, the outline of the auxiliary base plate 4 is larger than that of the lower base plate 2. The lower end face of the protruding edge of the lower base plate 2 is provided with a slot 23 for accommodating the upper support plate, maintaining stability during the support process. When the support structure 9 is used to support the lower base plate 2 and the auxiliary base plate 4, which form an acute angle, the support structure is located on both sides of the auxiliary base plate 4.

[0044] The sand sampler fixing device provided in this embodiment is used for fixing the sand sampler on a flat ground surface. The auxiliary base plate 4 is parallel and fitted to the lower base plate 2. The positioning pin 5 passes through the first through hole 21 of the lower base plate 2 and the strip hole 41 of the auxiliary base plate 4 in sequence before entering the ground, achieving initial anchoring of the device to the ground. A secondary anchoring is achieved by using an anchor rod passing through the connecting hole 61 of the connecting block 6, further ensuring the stable fixing of the device. Figure 1 and Figure 2 As shown.

[0045] The fixing device for the sand sampler in the hydraulic geotechnical investigation provided in this embodiment is as follows: Figures 3-5 As shown, when fixing the sand extractor on a sloping ground, the auxiliary base plate 4 rotates relative to the lower base plate 2 around the through shaft 8 until it is at the same angle to the ground, forming an acute angle. At the same time, a support structure 9 with a matching height is used to support the lower base plate 2. The upper support plate 91 is inserted into the slot 23 of the lower base plate 2, and the lower support plate 92 is anchored to the ground through the fixing hole 94. The two ends of the support column 93 are rotatably connected to form a stable triangular support. Since the outline of the auxiliary base plate 4 is larger than that of the lower base plate 2, the projections of the first through hole 21 and the through hole 3 on the auxiliary base plate 4 always fall within the strip hole 41 and the waist-shaped hole 43, and the positioning pin 5 and the sand extractor can pass through and be fixed smoothly. At this time, the connecting block 6 is in close contact with the sloping ground, and the anchor rod passes through the connecting hole 61, which can realize the fit and anchoring of the entire device with the sloping ground.

[0046] The fixing device for the sand sampler in the hydraulic geotechnical investigation provided in this embodiment has an auxiliary base plate 4 that can rotate around the through shaft 8 to be parallel and in contact with the inclined plane, so that the connecting block 6 is always in contact with the bottom surface, realizing the fit and stable anchoring of the device to the ground. The support structure 9 is supported between the lower base plate 2 and the auxiliary base plate 4, forming a triangular support system, which further improves the stability of the device during the fixing process.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
