Description

Technical Field

[0001] The present invention relates to the technical field of exploration drilling protection equipment, and specifically relates to a protection device for soil and water loss in exploration drilling. Background Technique

[0002] Exploration work is one of the important working methods in engineering geological exploration. Engineering geological exploration includes geophysical exploration, drilling, pit exploration, etc. Drilling is an important means to obtain accurate geological data below the surface in engineering geological exploration. Drilling work in exploration should be carried out on the basis of surveying and mapping and geophysical exploration. Exploration lines and networks should be arranged purposefully and planned according to the exploration stage, project scale, and complexity of geological conditions. Generally, it is carried out according to the principles of first near then far, first shallow then deep, and first sparse then dense.

[0003] According to a protection device for soil and water loss in exploration drilling proposed in Chinese Patent CN218669236U, in this device, through the provision of a positioning protection mechanism, the overall structure is installed on the required soil through the positioning cone rod at the bottom of the support ring plate. The positioning nut is rotated so that the positioning nut disengages from the receiving threaded rod. After disengagement, the fixed ring plate is pulled upward, and the corrugated pipe is stretched and unfolded. After the corrugated pipe is unfolded, the positioning nut is connected to the locking threaded rod to fix the stretched distance between the fixed ring plate and the support ring plate, realizing the unfolding of the overall structure.

[0004] However, there are some deficiencies in this patent. When the corrugated pipe needs to be stretched and unfolded in this device to protect the drilling equipment, the operator rotates the positioning nut to make the threaded rod rotate so that the fixed ring plate rises to realize the unfolding of the corrugated pipe. In this process, it is necessary to rely on manual adjustment of the height of the corrugated pipe, and the adaptability to terrains such as slopes and wetlands is not considered, which is likely to affect the protection effect of the device on the drilling equipment. Therefore, we propose a protection device for soil and water loss in exploration drilling. Summary of the Invention

[0005] The purpose of the present invention is to provide a protection device for soil and water loss in exploration drilling, which solves the problems raised in the above background technique.

[0006] To achieve the above object, the present invention provides the following technical solution: An exploration drilling soil and water loss protection device, including an annular bottom plate, and an adjustment component arranged on the top of the annular bottom plate. The adjustment component includes a bellows fixedly connected to the top of the annular bottom plate. The top of the bellows is fixedly connected with an annular top plate. The top of the annular bottom plate is fixedly connected with a support frame. The inner wall of the top of the support frame is fixedly connected with a driving motor. The output end of the driving motor is fixedly connected with an output shaft. The outer wall of the other end of the output shaft is fixedly connected with a gear. The outer wall of the gear is engaged with a rack. The top of the rack is fixedly connected with the bottom of the annular top plate. The top of the side of the annular bottom plate is fixedly connected with a sleeve. The bottom of the inner wall of the sleeve is fixedly connected with a first spring. The other end of the first spring is fixedly connected with a limiting post. The top of the limiting post is fixedly connected with the bottom of the annular top plate. By setting the adjustment component, it is convenient to extend the bellows during the meshing of the gear and the rack, so as to realize the protection of the drilling equipment during the soil and water exploration process.

[0007] Preferably, a shock absorption component is arranged on the top of the annular top plate. The shock absorption component includes a chute opened on the top of the annular top plate. The inner wall of the chute is fixedly connected with a cross bar. The outer wall of the cross bar is slidably connected with a slider. The side wall of the slider is fixedly connected with a second spring. The other end of the second spring is fixedly connected with the inner wall of the chute. The top of the slider is movably connected with a support rod through a hinge. The other end of the support rod is movably connected with a bearing top plate through a hinge. By setting the shock absorption component, before the soil and water drilling is required, the drilling equipment needs to be fixedly installed on the inner wall of the top of the bearing top plate first. During the process of the drilling equipment drilling the soil and water, the drilling equipment is prone to vibration. In order to avoid the influence of the vibration of the drilling equipment on the working effect, it is necessary to shock-absorb the bearing top plate, so as to achieve the purpose of shock-absorbing the drilling equipment. When the drilling equipment generates vibration, it will drive the bearing top plate to move downward, prompting the bearing top plate to squeeze the support rod, causing the support rod to rotate, and pushing the slider to move horizontally along the outer wall of the cross bar. Under the action of the second spring on the slider, it is convenient to achieve the purpose of shock-absorbing the bearing top plate during the up and down vibration process.

[0008] Preferably, a damper is fixedly connected to the top of the annular top plate. The other end of the damper is fixedly connected with the bottom of the bearing top plate. By setting the damper, it can more effectively shock-absorb the bearing top plate under the action of the second spring.

[0009] Preferably, a fixing component is provided on the side wall of the annular bottom plate. The fixing component includes a rectangular groove formed inside the side surface of the annular bottom plate. A third spring is fixedly connected to the inner wall of the rectangular groove. The other end of the third spring is fixedly connected to a displacement block. The outer wall of the displacement block is slidably connected to the inner wall of the rectangular groove. A connecting block is fixedly connected to the side wall of the displacement block. The other end of the connecting block is fixedly connected to an arc-shaped block. The outer wall of the arc-shaped block is movably connected to a movable plate through a hinge. A screw rod is threadedly connected to the inner wall of the movable plate. A regulating block is fixedly connected to the outer wall of the top of the screw rod. The bottom of the screw rod is rotatably connected to a positioning cone rod. By providing the fixing component, when the device needs to be used, in order to improve the stability of the device during operation, the position of the device needs to be fixed. The operator places the device at a designated working location, and then pulls the arc-shaped block, causing the arc-shaped block to pull the connecting block and the displacement block, extending the third spring. Then, the operator flips the movable plate to facilitate positioning and installing the device on the surface of the slope. Subsequently, the operator rotates the regulating block to cause the screw rod to rotate. During the rotation of the screw rod, the positioning cone rod will move downward, inserting the positioning cone rod into the ground, thereby improving the stability of the device during use.

[0010] Preferably, the fixing component further includes insertion rods fixedly connected to the bottom of the annular bottom plate. The number of the insertion rods is several, and several insertion rods are circumferentially arranged on the bottom of the annular bottom plate along the central axis of the annular bottom plate. By providing multiple insertion rods at the bottom of the annular bottom plate, it is convenient to achieve the supporting effect on the device.

[0011] Preferably, the outer wall of the bottom of the limiting post is adapted to the inner wall of the sleeve. The bottom of the limiting post is fixedly connected to one end of the first spring. By providing the first spring, it is convenient to limit the limiting post during the sliding process of the limiting post inside the sleeve.

[0015] (1) The soil and water loss prevention device for exploration drilling, by setting an adjustment component, when drilling for soil and water loss, in order to improve the exploration effect, the corrugated pipe needs to be propped up, so as to protect the drilling equipment. At this time, the operator turns on the driving motor to make the output shaft rotate. During the rotation of the output shaft, the gear will rotate. During the rotation of the gear, it will mesh with the rack, causing the rack to move upward and pushing the annular top plate upward, thus realizing the extension of the corrugated pipe. The operation process is simple and rapid. When the annular top plate moves upward, the limit post will slide inside the sleeve, which is convenient for improving the stability during the propping-up process of the annular top plate;

[0016] (2) The soil and water loss prevention device for exploration drilling, by setting a shock absorption component, before soil and water drilling is required, first, the drilling equipment needs to be fixedly installed on the inner wall of the top of the bearing top plate. During the process of the drilling equipment drilling soil and water, the drilling equipment is prone to vibration. In order to prevent the drilling equipment from being affected by vibration and affecting the working effect, it is necessary to shock-absorb the bearing top plate, so as to achieve the purpose of shock-absorbing the drilling equipment. When the drilling equipment vibrates, it will drive the bearing top plate to move downward, causing the bearing top plate to squeeze the support rod, causing the support rod to rotate and pushing the slider to move horizontally along the outer wall of the cross bar. Under the action of the second spring on the slider, it is convenient to achieve the purpose of shock-absorbing the bearing top plate during the up and down vibration process. By setting a damper, it can cooperate with the second spring to more effectively shock-absorb the bearing top plate;

[0017] (3) The soil and water loss prevention device for exploration drilling, by setting a fixing component, when the device needs to be used, in order to improve the stability during the working process of the device, the position of the device needs to be fixed. The operator places the device at the designated working location, and then pulls the arc-shaped block, causing the arc-shaped block to pull the connecting block and the displacement block, causing the third spring to extend. Then, the movable plate is flipped, which is convenient for the operator to position and install the device on the surface of the slope. Subsequently, the operator rotates the adjusting block to make the screw rotate. During the rotation of the screw, the positioning cone rod will move downward, and the positioning cone rod will be inserted into the soil to improve the stability of the device during use. By setting a plurality of insertion rods at the bottom of the annular bottom plate, it is convenient to realize the supporting effect of the device. Description of the Drawings

The other end of the support rod 225 is movably connected to a bearing top plate 226 through a hinge. By providing the shock-absorbing component 22, before the soil and water drilling is required, first, the drilling equipment needs to be fixedly installed on the inner wall of the top of the bearing top plate 226. During the process of the drilling equipment drilling the soil and water, the drilling equipment is likely to generate vibrations. In order to prevent the drilling equipment from being affected by vibrations and affecting the working effect, it is necessary to shock-absorb the bearing top plate 226, so as to achieve the purpose of shock-absorbing the drilling equipment. When the drilling equipment generates vibrations, it will drive the bearing top plate 226 to move downward, causing the bearing top plate 226 to squeeze the support rod 225, causing the support rod 225 to rotate, and pushing the slider 223 to move horizontally along the outer wall of the cross bar 222.

An adjusting block 238 is fixedly connected to the top outer wall of the screw rod 237. The bottom of the screw rod 237 is rotatably connected to a positioning cone rod 239. By providing the fixing component 23, when the device needs to be used, in order to improve the stability of the device during operation, the position of the device needs to be fixed. The operator places the device at the designated working location, and then pulls the arc-shaped block 235, causing the arc-shaped block 235 to pull the connecting block 234 and the displacement block 233, causing the third spring 232 to extend. Then, the movable plate 236 is flipped, facilitating the operator to position and install the device on the surface of the slope. Subsequently, the operator rotates the adjusting block 238, causing the screw rod 237 to rotate. During the rotation of the screw rod 237, the positioning cone rod 239 will move downward, inserting the positioning cone rod 239 into the soil, thereby improving the stability of the device during use.

[0031] The fixing component 23 further includes insertion rods 2310 fixedly connected to the bottom of the annular bottom plate 1. The number of the insertion rods 2310 is several, and several insertion rods 2310 are circumferentially arranged on the bottom of the annular bottom plate 1 along the central axis of the annular bottom plate 1. By providing a plurality of insertion rods 2310 at the bottom of the annular bottom plate 1, it is convenient to realize the supporting effect on the device.

[0034] In addition, the number of the positioning cone rods 239 is three, and three positioning cone rods 239 are circumferentially arranged on the outer wall of the annular bottom plate 1. By providing three positioning cone rods 239, it is convenient for the operator to fix the position of the device.

[0035] Working principle: When using the device, in order to improve the stability during the operation of the device, it is necessary to fix the position of the device. The operator places the device at the designated working location, and then pulls the arc-shaped block 235, causing the arc-shaped block 235 to pull the connecting block 234 and the displacement block 233, extending the third spring 232. Then, the movable plate 236 is flipped to facilitate the operator to position and install the device on the surface of the slope. Subsequently, the operator rotates the adjustment block 238 to cause the screw rod 237 to rotate. During the rotation of the screw rod 237, the positioning cone rod 239 will move downward, inserting the positioning cone rod 239 into the soil to improve the stability of the device during use;

[0036] Before the soil and water drilling is required, first, the drilling equipment needs to be fixedly installed on the inner wall of the top of the bearing top plate 226. During the process of the drilling equipment drilling the soil and water, the drilling equipment is prone to vibration. In order to prevent the drilling equipment from being affected by vibration and affecting the working effect, it is necessary to damp the bearing top plate 226 to achieve the purpose of damping the drilling equipment. When the drilling equipment vibrates, it will drive the bearing top plate 226 to move downward, causing the bearing top plate 226 to squeeze the support rod 225, causing the support rod 225 to rotate and pushing the slider 223 to move horizontally along the outer wall of the cross bar 222. Under the action of the second spring 224 on the slider 223, it is possible to facilitate the damping of the bearing top plate 226 during the up and down vibration. By setting the damper 227, it can cooperate with the second spring 224 to more effectively damp the bearing top plate 226;

[0037] When drilling soil and water loss, in order to improve the exploration effect, it is necessary to prop up the corrugated pipe 211 to achieve the protection of the drilling equipment. At this time, the operator turns on the drive motor 214 to cause the output shaft 215 to rotate. During the rotation of the output shaft 215, the gear 216 will be caused to rotate. During the rotation of the gear 216, it will engage with the rack 217, causing the rack 217 to move upward and causing the rack 217 to push the annular top plate 212 upward, thereby realizing the extension of the corrugated pipe 211. The operation process is simple and rapid. When the annular top plate 212 moves upward, it will cause the limit post 2110 to slide inside the sleeve 218, thus facilitating the improvement of the stability during the propping up of the annular top plate 212.
