Description

Technical Field

[0001] The invention belongs to the technical field of geological survey, and in particular relates to a portable surveying and mapping instrument for geological survey. Background Art

[0002] The surveying instrument for geological survey is an instrument specially used for geological exploration and measurement. It can determine key information such as geographical location, topography, and geological structure with high precision through advanced measurement technology and navigation technology. It has technical characteristics such as high precision, versatility, and portability, and plays an important role in the fields of mineral resource exploration, geological environment monitoring, and engineering construction. Conventional surveying instruments for geological surveys mainly consist of a surveying instrument at the top and a bracket at the bottom. When conducting geological surveys, the surveying instrument is often unfolded and supported by the bracket at the bottom. After the support is completed, the surveying instrument needs to be adjusted to keep it vertical to the ground. The entire adjustment process requires the horizontal and vertical states of the surveying instrument to be adjusted. The entire adjustment process is relatively complicated and cannot achieve a quick leveling process.

[0003] At the same time, when unfolding the surveying instrument, the support angles of at least three brackets need to be adjusted, that is, support is performed first and then leveling is performed. However, when unfolding the brackets, it is difficult to quickly adjust multiple brackets to the appropriate angles, resulting in a long support preparation process, which urgently needs to be improved. Summary of the invention

[0004] The object of the present invention is to provide a portable surveying instrument for geological surveying to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a portable surveying instrument for geological survey, comprising a base, an auxiliary support assembly is axially evenly installed on the bottom end of the base, a self-leveling assembly is fixedly installed on the top end of the base, an upper extension frame is fixedly installed on the top end of the middle part of the self-leveling assembly, a surveying instrument body is fixedly installed on the top end of the upper extension frame, a lower extension frame is fixedly installed on the bottom end of the self-leveling assembly, a vertical rope is fixedly installed on the bottom end of the lower extension frame, a plumb bob is fixedly installed on the bottom end of the vertical rope, extended iron blocks are axially evenly installed on the middle part of the outer side surface of the plumb bob, the number of the extended iron blocks is the same as the number of the auxiliary support assemblies, and the extended iron blocks are adsorption-connected to the auxiliary support assemblies.

[0006] Before use, the device is in a stored state, that is, the plumb bob is at the highest point, and the auxiliary support assembly is in a stored state, that is, the spacing between multiple auxiliary support assemblies is the minimum. At this time, the device is in an unfolded state, and the device can be carried to the area to be surveyed and wait for unfolding. At the same time, before unfolding, the auxiliary support assembly and the extended iron block are in an adsorbed and fixed state for rapid storage and unfolding of the device.

[0007] As a further technical solution of the present invention, the self-leveling assembly includes a fixing ring, a mounting seat is fixedly installed at the bottom end of the fixing ring, the middle part of the bottom end of the mounting seat is connected to the middle part of the top end of the base, and an arc-shaped groove is opened on the inner side surface of the fixing ring.

[0008] As a further technical solution of the present invention, a vertical movable ring is provided on the inner side surface of the fixed ring, and arc-shaped clamping strips are fixedly installed on the upper and lower ends of the outer side surface of the vertical movable ring. The vertical movable ring is movably clamped between the arc-shaped clamping strip and the arc-shaped clamping groove, and the vertical movable ring rotates left and right relative to the fixed ring.

[0009] As a further technical solution of the present invention, a horizontal movable ring is provided on the inner side surface of the vertical movable ring, and mounting parts are fixedly installed at the upper and lower ends of the middle part of the horizontal movable ring, the upper mounting part is connected to the upper extension frame, and the lower mounting part is connected to the lower extension frame.

[0010] As a further technical solution of the present invention, the horizontal movable ring is movably installed inside the vertical movable ring in a horizontal state, and the horizontal movable ring rotates back and forth relative to the vertical movable ring.

[0011] When the device is unfolded and the surveying instrument body needs to be leveled, the adsorption and fixation between all the extended iron blocks and the magnets can be released. The plumb bob can now swing freely and swing left and right and back and forth under the action of gravity. When the plumb bob swings left and right, the vertical movable ring rotates left and right relative to the fixed ring, and drives the horizontal movable ring to swing left and right synchronously, and drives the surveying instrument body to swing left and right. When the plumb bob swings back and forth, the horizontal movable ring rotates back and forth relative to the vertical movable ring, and finally drives the surveying instrument body to swing back and forth until the plumb bob stops moving and is perpendicular to the ground. At this time, the surveying instrument body is also in a vertical state, completing the automatic leveling process.

[0012] By utilizing the cooperation between the plumb bob and the self-leveling component and the gravity of the plumb bob, the plumb state of the plumb bob is applied to the self-leveling component and converted into two states, left-right swinging and front-back swinging. The state is then reflected in the surveying instrument body to swing the surveying instrument body left-right and front-back swinging, thereby completing the automatic leveling process of the surveying instrument body. The entire process can be completed automatically without the complicated adjustment process of traditional devices, effectively shortening the leveling time, reducing the difficulty of leveling, and improving the surveying quality.

[0013] As a further technical solution of the present invention, the auxiliary support assembly includes a first fixed seat, which is fixedly installed at the bottom end of the base at axial equal intervals, and one end of the first fixed seat away from the base is movably connected to a support rod through a rotating shaft.

[0014] As a further technical solution of the present invention, a second fixing seat is fixedly installed in the middle of the inner side surface of the support rod, and an end of the second fixing seat away from the support rod is movably connected to an adjusting rod through a rotating shaft.

[0015] As a further technical solution of the present invention, one end of the adjusting rod away from the second fixing seat is movably connected to the third fixing seat via a rotating shaft, and one end of the third fixing seat away from the adjusting rod is fixedly mounted with a magnet.

[0016] As a further technical solution of the present invention, when the plumb bob is located in the middle of the base, the extended iron block on the outer side of the plumb bob is adsorbed and connected to the magnet.

[0017] When the device is deployed, it is first necessary to ensure that the auxiliary support assembly and the extended iron block are in an adsorption state. After the adsorption state is confirmed, the plumb bob can be initially released, and the plumb bob automatically drops and falls until the vertical rope is straightened. When the plumb bob drops, the multiple adjustment rods are deflected toward the outer side and gradually rotated to a horizontal state. At this time, a thrust can be applied to the support rod, and the support rod rotates toward the outer side relative to the first fixed seat, that is, the deployment of multiple support rods is completed, and the multiple support rods are deployed simultaneously, completing the rapid deployment process; When storing, it is only necessary to continue to maintain the adsorption state between the extended iron block and the magnet, and pull the plumb bob upward to drive the multiple adjustment rods to deflect toward the middle until the multiple adjustment rods are transformed into an approximately vertical state, and then a pulling force can be applied to the multiple support rods. At this time, the multiple support rods are relatively close to each other until the storage process is completed.

[0018] By utilizing the automatic release of the plumb bob and the manual rising process, that is, utilizing the force of gravity to quickly act on the auxiliary support assembly, the auxiliary support assembly can quickly complete the unfolding process. The entire unfolding process can be completed quickly, and the three support rods can be controlled at the same time, so that the device can quickly switch to the unfolded state and can quickly switch to the stored state, effectively shortening the preparation time for unfolding and storing of traditional devices, reducing preparation time, and improving surveying and mapping efficiency.

[0019] The beneficial effects of the present invention are as follows: (1) The present invention utilizes the automatic release of the plumb bob and the manual rising process, that is, utilizes the force of gravity to quickly act on the auxiliary support assembly, so that the auxiliary support assembly can quickly complete the deployment process. The entire deployment process can be completed quickly, and the three support rods can be controlled at the same time, so that the device can be quickly switched to the deployed state and can also be quickly switched to the stored state, effectively shortening the preparation time for deployment and storage of traditional devices, reducing preparation time, and improving surveying and mapping efficiency.

[0020] (2) The present invention utilizes the cooperation between the plumb bob and the self-leveling component and the gravity of the plumb bob, that is, the plumb state of the plumb bob acts on the self-leveling component and transforms it into two states: left-right swinging and front-back swinging. The state is reflected in the surveying instrument body to swing the surveying instrument body left-right and front-back swinging, thereby completing the automatic leveling process of the surveying instrument body. The whole process can be completed automatically without the complicated adjustment process of the traditional device, effectively shortening the leveling time, reducing the leveling difficulty, and improving the surveying quality.

[0025] The surveying instrument body 5 adopts an integrated RTK measuring instrument.

[0026] Before use, the device is in a stored state, that is, the plumb bob 8 is at the highest point, and the auxiliary support assembly 2 is in a stored state, that is, the spacing between multiple auxiliary support assemblies 2 is the minimum. At this time, the device is in an unfolded state, and the device can be carried to the area to be surveyed and wait for unfolding. At the same time, before unfolding, the auxiliary support assembly 2 and the extended iron block 9 are in an adsorbed and fixed state for rapid storage and unfolding of the device.

[0027] like Figure 1 and Figure 2 as well as Figure 4 As shown, the self-leveling component 3 includes a fixing ring 301, a mounting seat 303 is fixedly installed at the bottom end of the fixing ring 301, the middle part of the bottom end of the mounting seat 303 is connected to the middle part of the top end of the base 1, an arc-shaped groove 302 is opened on the inner side of the fixing ring 301, a vertical movable ring 304 is provided on the inner side of the fixing ring 301, and arc-shaped clamping strips 305 are fixedly installed on the upper and lower ends of the outer side of the vertical movable ring 304, and the vertical movable ring 304 is movably clamped between the arc-shaped clamping strip 305 and the arc-shaped groove 302, and the vertical movable ring 304 is movably clamped.

The horizontal movable ring 306 is movably installed inside the vertical movable ring 304 in a horizontal state, and the horizontal movable ring 306 rotates back and forth relative to the vertical movable ring 304.

[0028] Embodiment: When the device is unfolded and the surveying instrument body 5 needs to be leveled, the adsorption and fixation between all the extended iron blocks 9 and the magnets 206 can be released. At this time, the plumb bob 8 can swing freely, and swing left and right and back and forth under the action of gravity. When the plumb bob 8 swings left and right, the vertical movable ring 304 rotates left and right relative to the fixed ring 301, and drives the horizontal movable ring 306 to swing left and right synchronously, and drives the surveying instrument body 5 to swing left and right. When the plumb bob 8 swings back and forth, the horizontal movable ring 306 rotates back and forth relative to the vertical movable ring 304, and finally drives the surveying instrument body 5 to swing back and forth until the plumb bob 8 stops moving. At this time, it can be perpendicular to the ground. At this time, the surveying instrument body 5 is also in a vertical state, and the automatic leveling process is completed.

[0029] By utilizing the cooperation between the plumb bob 8 and the self-leveling component 3 and utilizing the gravity of the plumb bob 8, the plumb state of the plumb bob 8 is applied to the self-leveling component 3 and converted into two states, namely, left-right swinging and front-back swinging. The state is then reflected to the surveying instrument body 5 to perform the left-right swinging and front-back swinging of the surveying instrument body 5, thereby completing the automatic leveling process of the surveying instrument body 5. The entire process can be completed automatically without the need for the complicated adjustment process of the traditional device, thereby effectively shortening the leveling time, reducing the leveling difficulty, and improving the surveying and mapping quality.

[0030] like Figure 1 and Figure 6 as well as Figure 7 As shown, the auxiliary support assembly 2 includes a first fixed seat 201, which is fixedly installed on the bottom end of the base 1 at an axially equidistant interval, the end of the first fixed seat 201 away from the base 1 is movably connected to the support rod 203 through a rotating shaft, the middle of the inner side of the support rod 203 is fixedly installed with a second fixed seat 202, the end of the second fixed seat 202 away from the support rod 203 is movably connected to the adjusting rod 205 through a rotating shaft, the end of the adjusting rod 205 away from the second fixed seat 202 is movably connected to the third fixed seat 204 through a rotating shaft, the end of the third fixed seat 204 away from the adjusting rod 205 is fixedly installed with a magnet 206, and when the plumb bob 8 is located in the middle of the base 1, the extended iron block 9 on the outer side of the plumb bob 8 is adsorbed and connected with the magnet 206.

[0031] Embodiment: When the device is deployed, it is first necessary to ensure that the auxiliary support assembly 2 and the extended iron block 9 maintain an adsorption state. After the adsorption state is confirmed, the plumb bob 8 can be initially released, and the plumb bob 8 automatically drops and falls until the vertical rope 7 is straightened. When the plumb bob 8 drops, the multiple adjustment rods 205 are deflected toward the outer side and gradually rotated to a horizontal state. At this time, a thrust can be applied to the support rod 203, and the support rod 203 is rotated toward the outer side relative to the first fixed seat 201, that is, the deployment of the multiple support rods 203 is completed, and the multiple support rods 203 are deployed at the same time, completing the rapid deployment process; When storing, it is only necessary to continue to maintain the adsorption state between the extended iron block 9 and the magnet 206, and pull the plumb bob 8 upward to drive the multiple adjustment rods 205 to deflect toward the middle until the multiple adjustment rods 205 are transformed into an approximately vertical state, and then a pulling force can be applied to the multiple support rods 203. At this time, the multiple support rods 203 are relatively close to each other until the storage process is completed.

[0032] By utilizing the automatic release of the plumb bob 8 and the manual rising process, that is, utilizing the force of gravity to quickly act on the auxiliary support assembly 2, the auxiliary support assembly 2 can quickly complete the unfolding process, and the entire unfolding process can be completed quickly. The three support rods 203 can be controlled at the same time, so that the device can quickly switch to the unfolded state and can also quickly switch to the stored state, effectively shortening the preparation time for unfolding and storing of traditional devices, reducing preparation time, and improving surveying and mapping efficiency.

[0033] Working principle and usage process: Before use, the device is in a stowed state, that is, the plumb bob 8 is at the highest point, and the auxiliary support assembly 2 is in a stowed state, that is, the spacing between multiple auxiliary support assemblies 2 is the minimum value. At this time, the device is in an undeployed state, and the device can be carried to the area to be surveyed and wait for deployment. At the same time, before deployment, the auxiliary support assembly 2 and the extended iron block 9 are in an adsorption fixed state, which is used for rapid storage and deployment of the device; When the device is deployed, it is first necessary to ensure that the auxiliary support assembly 2 and the extended iron block 9 maintain an adsorption state. After the adsorption state is confirmed, the plumb bob 8 can be initially released, and the plumb bob 8 automatically drops and falls until the vertical rope 7 is straightened. When the plumb bob 8 drops, the multiple adjustment rods 205 are deflected toward the outer side and gradually rotated to a horizontal state. At this time, a thrust can be applied to the support rod 203, and the support rod 203 is rotated toward the outer side relative to the first fixed seat 201, that is, the deployment of the multiple support rods 203 is completed, and the multiple support rods 203 are deployed at the same time, completing the rapid deployment process; When storing, it is only necessary to continue to maintain the adsorption state between the extended iron block 9 and the magnet 206, and pull the plumb bob 8 upward to drive the multiple adjustment rods 205 to deflect toward the middle, until the multiple adjustment rods 205 are transformed into a nearly vertical state, and then a pulling force can be applied to the multiple support rods 203, and the multiple support rods 203 are relatively close to each other until the storage process is completed; When the device is unfolded and the surveying instrument body 5 needs to be leveled, the adsorption and fixation between all the extended iron blocks 9 and the magnets 206 can be released. At this time, the plumb bob 8 can swing freely, and swing left and right and back and forth under the action of gravity. When the plumb bob 8 swings left and right, the vertical movable ring 304 rotates left and right relative to the fixed ring 301, and drives the horizontal movable ring 306 to swing left and right synchronously, and drives the surveying instrument body 5 to swing left and right. When the plumb bob 8 swings back and forth, the horizontal movable ring 306 rotates back and forth relative to the vertical movable ring 304, and finally drives the surveying instrument body 5 to swing back and forth until the plumb bob 8 stops moving and is perpendicular to the ground. At this time, the surveying instrument body 5 is also in a vertical state, and the automatic leveling process is completed.
