However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0030] Example
[0031] Reference Figure 1-6 This is an embodiment of the present invention, which provides a petroleum hydrocarbon contaminated soil sampling drill, comprising,
[0032] The soil sampling mechanism 100 includes a mounting frame 110, a vertical rod 120 slidably mounted on the mounting frame 110, a sampling drill 130 fixed to the bottom of the vertical rod 120 and used for sampling, an operating rod 140 fixed to the top of the vertical rod 120, and two return springs 150 symmetrically fixed to the top of the mounting frame 110 and used for the vertical rod 120 to automatically return to its upward position.
[0033] The sampling depth control mechanism 200 includes a depth adjustment component 210 for controlling the sampling depth of the sampling drill 130, and an anti-collision component 220 used in conjunction with the depth adjustment component 210 to prevent accidental collision.
[0034] The depth adjustment component 210 can precisely control the sampling depth of the sampling drill 130. Through its own structure, it can flexibly set different sampling depths according to the actual needs of sampling petroleum hydrocarbon contaminated soil, solving the problem of traditional sampling drills relying on manual experience and having low depth control accuracy, and ensuring uniform sampling depth at different points. The anti-collision component 220 can be used in conjunction with the depth adjustment component 210 to effectively prevent the preset state of the depth adjustment component 210 from changing due to accidental collision during equipment handling and operation, and prevent the sampling depth from deviating unexpectedly.
[0035] Specifically, the depth adjustment component 210 includes a slide groove on the side of the mounting frame 110, a slider 211 slidably installed inside the slide groove, a baffle 212 fixed to one side of the slider 211, a side box 213 fixed to the other side of the slider 211, two L-shaped clamping plates 214 disposed inside the side box 213, two side strips 215 fixed to one side of the mounting frame 110 and located on both sides of the side box 213, a plurality of slots 216 equidistantly opened on the surface of the side strips 215 and used in conjunction with the L-shaped clamping plates 214, and a first spring 217 fixed between the two L-shaped clamping plates 214;
[0036] The end of the L-shaped clamp 214 is engaged with the inside of the clamping slot 216. The first spring 217 is used to maintain the elasticity of the two L-shaped clamps 214. Two protrusions 160 are fixedly installed on the surface of the vertical rod 120. The baffle 212 is used to block the protrusions 160 to control the sampling depth of the sampling drill 130.
[0037] The sliding engagement between the slide groove and the slider 211 allows the baffle 212 to move along the height of the mounting frame 110, thereby adjusting the blocking position of the baffle 212 on the protrusion 160 on the surface of the vertical rod 120, achieving precise control over the soil penetration depth of the sampling drill 130. The two L-shaped locking plates 214 inside the side box 213, under the elastic force of the first spring 217, are always locked into the slots 216 on the surface of the side strip 215 of the mounting frame 110, ensuring the stability of the slider 211 and baffle 212 after adjustment, preventing displacement due to vibration during sampling. Several equidistant slots 216 provide multiple fixed positions for depth adjustment, meeting the sampling needs at different depths and improving the applicability of the equipment.
[0038] Furthermore, a pressure plate 218 for easy pressing is fixedly installed on the surface of the L-shaped card plate 214, and the pressure plate 218 is located outside the side box 213.
[0039] In this way, the operator does not need to reach into the side box 213. He only needs to press the external pressure plate 218 to drive the L-shaped card plate 214 to compress the first spring 217 and disengage from the card slot 216, which simplifies the operation steps when adjusting the depth and reduces the difficulty of operation.
[0040] Preferably, a positioning rod 219 is fixedly installed inside the side box 213, and a positioning hole for use with the positioning rod 219 is opened on the surface of the L-shaped plate 214.
[0041] The positioning rod 219 fixed inside the side box 213 cooperates with the positioning hole on the surface of the L-shaped card plate 214 to accurately guide the movement direction of the L-shaped card plate 214, ensuring that the L-shaped card plate 214 always moves in the preset direction during compression or reset, and avoiding the inability to accurately engage with or disengage from the card slot 216 due to the offset of the L-shaped card plate 214.
[0042] Furthermore, the anti-accidental contact component 220 includes a trigger 221 that is triggered by the movement of the L-shaped plate 214, and an abutment 222 that works in conjunction with the trigger 221 to limit the movement of the two L-shaped plates 214.
[0043] The trigger 221 and the abutment 222 work together to limit the two L-shaped plates 214 when the equipment is not being adjusted. This prevents the L-shaped plates 214 from accidentally dislodging from the slots 216 due to operator accidental contact with the pressure plate 218 or vibration during equipment handling, thus avoiding positional shift of the slider 211 and the baffle 212. The abutment 222 will only release the limit on the L-shaped plates 214 when the operator actively releases it, ensuring that depth adjustment is only performed under human control. This significantly improves the stability of the equipment during use and avoids sampling depth deviation due to accidental contact.
[0044] Specifically, the trigger 221 includes two fixed vertical plates 2211 symmetrically fixed to the top of the side box 213, a second spring 2212 fixed to the top of the fixed vertical plate 2211, a moving rod 2213 fixed to the other end face of the second spring 2212 and used to move in conjunction with the L-shaped card plate 214, and a side groove 2214 opened on the surface of the fixed vertical plate 2211.
[0045] The bottom of the moving rod 2213 is located at the top of the L-shaped card plate 214 and is set at an angle.
[0046] The inclined design at the bottom of the moving rod 2213 allows the L-shaped card plate 214 to move towards the inner wall of the side box 213, thereby pushing the moving rod 2213 upward to compress the second spring 2212 and achieving automatic linkage of the trigger action without the need for additional manual operation of the triggering component 221. The side groove 2214 on the surface of the fixed vertical plate 2211 provides a matching structure for the limiting of the abutment component 222, ensuring smooth connection between the triggering component 221 and the abutment component 222, and further improving the reliability of the anti-accidental collision function.
[0047] Furthermore, the abutment member 222 includes a tension spring 2221 fixed to the top of the side box 213 and located between the two fixed vertical plates 2211, a horizontal plate 2222 fixed to the top of the tension spring 2221, an abutment plate 2223 fixed to the bottom of the horizontal plate 2222 and used to abut and limit the two L-shaped plates 214, and a side block 2224 elastically installed on the side of the horizontal plate 2222 and used in conjunction with the side groove 2214;
[0048] The top of the moving rod 2213 is used to push the side block 2224 out of the interior of the side groove 2214.
[0049] Among them, the tension spring 2221 can always apply a downward pulling force to the horizontal plate 2222, so that the bottom abutment plate 2223 keeps abutting against the L-shaped card plate 214, restricting the L-shaped card plate 214 from moving into the side box 213, and realizing the anti-accidental collision limit.
[0050] In use, the operator presses the two pressure plates 218 on the outside of the side box 213 by hand, which causes the L-shaped clamping plate 214 inside the side box 213 to compress the first spring 217, so that the end of the L-shaped clamping plate 214 disengages from the groove 216 on the surface of the side strip 215; at this time, the slider 211 moves up and down along the sliding groove on the side of the mounting frame 110, which causes the baffle 212 to move to the position corresponding to the preset sampling depth. The pressure plates 218 are released, the first spring 217 resets and pushes the L-shaped clamping plate 214 to re-clamp into the groove 216 at the corresponding position, thus completing the sampling depth fixation.
[0051] After the depth is preset, the L-shaped clamping plate 214 moves under the elastic force of the first spring 217 and presses the moving rod 2213, causing it to move upward. Then, the top of the moving rod 2213 presses the side block 2224 that is clamped inside the side groove 2214, causing the side block 2224 to disengage from the inside of the side groove 2214. At this time, the tension spring 2221 releases its elastic force and pulls the horizontal plate 2222 downward, so that the abutment plate 2223 abuts against the top of the L-shaped clamping plate 214, restricting the movement of the L-shaped clamping plate 214.
[0052] Soil sampling operation: The operator holds the operating rod 140 at the top of the vertical rod 120 with both hands and presses the operating rod 140 down, which drives the vertical rod 120 to slide down along the mounting frame 110, thereby driving the bottom sampling drill 130 into the soil; when the protrusion 160 on the surface of the vertical rod 120 moves down to contact the baffle 212, the baffle 212 prevents the protrusion 160 from moving down further, the sampling drill 130 reaches the preset sampling depth, and the pressing stops.
[0053] In summary, the depth adjustment component 210 can precisely control the sampling depth of the sampling drill 130. Through its own structural cooperation, different sampling depths can be flexibly set according to the actual needs of sampling petroleum hydrocarbon contaminated soil, solving the problem of traditional sampling drills relying on manual experience and having low depth control accuracy, and ensuring uniform sampling depth at different points. The anti-collision component 220 can be used in conjunction with the depth adjustment component 210 to effectively prevent the preset state of the depth adjustment component 210 from changing due to accidental collision during equipment handling and operation, and prevent the sampling depth from deviating unexpectedly.
