Description

Technical Field

[0001] The present invention belongs to the technical field of exploration equipment, and specifically relates to a multifunctional geological compass for geological and mineral exploration. Background Art

[0002] A geological compass, also known as a "pocket theodolite", is one of the basic tools commonly used in geological and mineral exploration, mainly used to determine directions, measure dips, trends, and other geological parameters.

[0003] A geological compass mainly consists of a chassis, a box cover, a magnetic needle, a scale disk, etc. When using a geological compass to measure the attitude of rock strata, it is usually necessary to bring the geological compass into contact with the rock strata and adjust the direction and angle of the geological compass according to the measurement process to achieve the measurement of the attitude. After the geological compass completes the measurement, personnel need to conduct visual observation to determine the measurement value. Due to the requirements of its measurement process, the geological compass is in relatively close contact with the rock strata during the measurement, so the observation of the geological compass is difficult, and because the position of the protractor on the geological compass is relatively fixed, it is inconvenient to read the geological compass.

[0004] In related technologies, in order to improve the problem of difficult scale reading when a geological compass measures at inconvenient observation positions, a multifunctional geological compass for geological exploration and its usage method are disclosed, with the application number CN2024106700006. In this solution, by improving the geological compass, during the dip measurement process, by releasing the transmission column, it is driven by the spiral spring to drive the toothed ring to rotate. At this time, the dial inside the toothed ring makes a circular motion and emits a tapping sound along the convex block. The number of convex blocks corresponds to the angle, and the number of sound emissions corresponds to the convex block. Therefore, during the measurement, the dip angle can be judged by listening to the number of sound emissions. However, it is found during the experiment that, on the one hand, in order to maintain the small volume of the geological compass, the number of convex blocks is set to be small, and the angle corresponding to the convex block is too large, so the measurement reading error is large. On the other hand, when reading the dip angle, it is necessary to manually count the tapping sounds, and only one reading can be performed during a single measurement, which is not only prone to errors and omissions, but also inconvenient for reconfirmation.

[0005] In view of this, the present invention proposes a multifunctional geological compass for geological and mineral exploration to solve the above technical problems. Summary of the Invention

Detailed implementation manners

[0048] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0049] As Figures 1 to 10 shown, a multifunctional geological compass for geological and mineral exploration according to the present invention includes a chassis 1 and a top cover 11;

[0050] A rotating shaft 2 is fixedly installed on the top cover 11, a rotating groove 21 is formed on the chassis 1, and the top cover 11 and the chassis 1 are hinged through the rotating shaft 2 and the rotating groove 21;

[0051] A measuring groove 22 is formed on the chassis 1, a transparent cover 23 is fixedly installed at the opening of the measuring groove 22, a thimble 24 is rotatably installed in the measuring groove 22, and a magnetic needle 25 is rotatably installed on the thimble 24;

[0052] It further includes a braking mechanism, the braking mechanism is installed on the chassis 1, and the braking mechanism is used to fix the top cover 11 and the magnetic needle 25;

[0053] The braking mechanism includes:

[0054] A brake plate 3, an abutting groove 31 is formed on the chassis 1, the abutting groove 31 is conductively connected to the rotating groove 21, a brake plate 3 is elastically installed in the abutting groove 31 through an abutting spring 32, and the surfaces of the brake plate 3 and the rotating shaft 2 on the corresponding sides are rough;

[0055] A brake ring 33, a jacking groove 34 is formed in the measuring groove 22, a brake ring 33 is elastically installed in the jacking groove 34 through a jacking spring 35, and the brake ring 33 is located below the magnetic needle 25;

[0056] In the initial state, the brake plate 3 abuts against the rotating shaft 2, and the brake ring 33 abuts against the magnetic needle 25.

[0057] The braking mechanism further includes a pressing member 4. A pressing groove 41 is formed in the chassis 1, and the pressing member 4 is slidably installed in the pressing groove 41. A transmission groove 42 is formed in the chassis 1, and the transmission groove 42 is respectively connected in communication with the abutting groove 31 and the jacking groove 34. A transmission rope 43 is slidably installed in the transmission groove 42, and the transmission rope 43 connects the pressing member 4 with the brake plate 3 and the brake ring 33 respectively.

[0058] When measuring the characteristics such as the attitude of rock formations with a geological compass, due to the uneven surface characteristics of the rock formations, when the geological compass is measured according to the specifications of the measurement process, it is easy for the measurement value of the geological compass to be inconvenient to directly observe due to the occlusion of the rock formation, affecting the accuracy of the measurement value. Therefore, the present invention is provided with a braking mechanism. When measuring the rock formation parameters, the top cover 11 and the magnetic needle 25 are fixed through the braking mechanism, so that they are maintained and fixed at the measurement value, and then the geological compass is taken out for measurement, thereby enhancing the convenience and accuracy of the reading after the geological compass measurement.

[0059] Specifically, when measuring the attitude of rock strata, since the attitude of rock strata is divided into parameters such as strike, dip direction, and dip angle, different measurement techniques need to be adopted according to different measurement items during measurement. Among them, the value of dip angle measurement is finally reflected in the angle between the top cover 11 and the chassis 1, while the values of dip direction and strike are reflected in the deflection angle of the magnetic needle 25 in the measurement groove 22. Therefore, after the measurement is completed, only the relative positions of the top cover 11 and the chassis 1 and the position of the magnetic needle 25 need to be fixed to make the measurement values fixed. Then, the geological compass is taken out to an open area to facilitate reading the measurement values. During actual measurement, the exploration personnel need to manually attach the geological compass to the pre-selected test position, and then adjust the posture and angle of the geological compass according to the specifications of the measurement technique. During this process, the exploration personnel manually press the pressing member 4, causing the pressing member 4 to extend deep into the pressing groove 41. Since the pressing member 4 is connected to the brake plate 3 and the brake ring 33 through the transmission rope 43, and in the initial state, the brake plate 3 and the brake ring 33 are respectively in contact with the rotating shaft 2 and the magnetic needle 25, when the pressing member 4 pulls the transmission rope 43, it will cause the brake plate 3 and the brake ring 33 to compress the abutting spring 32 and the lifting spring 35 and move deep into the abutting groove 31 and the lifting groove 34 respectively. Finally, the brake plate 3 and the brake ring 33 are separated from the rotating shaft 2 and the magnetic needle 25 respectively. When the brake plate 3 is separated from the rotating shaft 2, the rotating shaft 2 is no longer restricted, enabling the top cover 11 and the chassis 1 to rotate relatively freely. When the brake ring 33 contracts into the lifting groove 34, the magnetic needle 25 is no longer restricted, causing the magnetic needle 25 to rotate on the thimble 24. Therefore, the geological compass can be measured according to the measurement technique. After the measurement is completed, the staff releases the pressure on the pressing member 4, so that the transmission rope becomes slack. At this time, under the action of the abutting spring 32 and the lifting spring 35 in the abutting groove 31 and the lifting groove 34, the brake plate 3 and the brake ring 33 are respectively in contact with the rotating shaft 2 and the magnetic needle 25. Under the fixing effect of friction, the relative angle between the top cover 11 and the chassis 1 is fixed, and the relative position between the magnetic needle 25 and the measurement groove 22 is fixed. After taking the geological compass out of the measurement position, the measurement values can be calculated or read.

[0060] By setting the braking mechanism, the present invention utilizes the fixing effect of the braking mechanism on the rotating shaft 2 and the magnetic needle 25. On the one hand, when the geological compass is not in use, the top cover 11 and the chassis 1 are relatively fixed to each other, and the magnetic needle 25 is separated from the thimble 24 under the pressure of the brake ring 33. This not only facilitates the storage of the geological compass but also avoids the collision between the magnetic needle 25 and the thimble 24 during storage, thereby reducing the failure rate of the geological compass. On the other hand, after the measurement is completed, by manually releasing the pressing member 4, the components of the geological compass can be fixed to a certain extent, so that the measurement values remain unchanged, facilitating the staff to calculate and read the measurement values.

[0061] As a preferred embodiment of the present invention, an L-shaped elastic clip 5 is fixedly installed on the top cover 11, a slot 51 is opened on the chassis 1, the slot 51 is conductively connected to the pressing groove 41, a limiting ring 52 is fixedly installed on the pressing member 4, and the limiting ring 52 is sleeved on the elastic clip 5 in the initial state.

[0062] In actual application, by installing the elastic card plate 5 on the top cover 11 and fixing the limit ring 52 on the pressing piece 4, after the use of the geological compass, the explorer manually closes the top cover 11 and the chassis 1, and then releases the pressure on the pressing piece 4. During the resetting process of the pressing piece 4, the limit ring 52 is sleeved on the elastic card plate 5, so that the top cover 11 and the chassis 1 are in a locked state. At the same time, the release of the pressing piece 4 causes the braking mechanism to brake the rotating shaft 2 and the magnetic needle 25, which further enhances the safety of the geological compass when not in use.

[0063] As a preferred embodiment of the present invention, the brake ring 33 is composed of a ring body and an elastic layer, and the elastic layer is fixedly installed on the side of the ring body facing the magnetic needle 25.

[0064] The presence of the ring body and the elastic layer can form elastic compression when the brake ring 33 lifts and abuts the magnetic needle 25. On the one hand, the elastic compression reduces the probability of damage to the magnetic needle 25, and on the other hand, it can also avoid scratches on the transparent cover 23 during the compression process.

[0065] As a preferred embodiment of the present invention, it also includes a metering mechanism, which is installed on the chassis 1 and is used to visualize the measurement data;

[0066] The measuring mechanism comprises:

[0067] A metering belt 6, wherein the chassis 1 is fixedly mounted with a metering belt 6, wherein a first metering tube 61 and a second metering tube 62 are mounted in the metering belt 6, and the metering belt 6 is marked with scales;

[0068] An expansion ball 63, an expansion ball 63 is fixedly installed at one end of the metering belt 6 away from the chassis 1, the first metering tube 61 and the second metering tube 62 extend into the expansion ball 63 respectively, and the expansion ball 63 is filled with a plugging liquid;

[0069] A first capacity tube 64 and a second capacity tube 65, wherein the first capacity tube 64 and the second capacity tube 65 are respectively connected to the first metering tube 61 and the second metering tube 62, and the first capacity tube 64 and the second capacity tube 65 are both filled with metering liquid;

[0070] The first conversion component and the second conversion component are used to convert the measured value into the pressure inside the first capacity tube 64 and the second capacity tube 65.

[0071] The plugging liquid and the metering liquid are incompatible with each other and have different colors.

[0072] In order to further improve the convenience of measurement, a metering mechanism is arranged on the compass in the present invention for cooperation with the braking mechanism. During the exploration process, when the braking mechanism is started, the measurement data can be quickly visually displayed.

[0073] Specifically, during exploration measurement, when the pressing member 4 is released, causing the brake pad and the brake ring 33 to fix the rotating shaft 2 and the magnetic needle 25, with the assistance of the first conversion assembly and the second conversion assembly, the measurement value is converted into the pressure in the first capacity tube 64 and the second capacity tube 65. Since the capacities of the first capacity tube 64 and the second capacity tube 65 are determined, under the action of the pressure, the metering liquid in the first capacity tube 64 and the second capacity tube 65 flows into the first metering tube 61 and the second metering tube 62 under the action of the pressure and pushes the plugging liquid. The excess plugging liquid is pushed into the expansion ball 63. Since the plugging liquid and the metering liquid are incompatible with each other and have different colors, the boundary between the plugging liquid and the metering liquid is relatively obvious, and the metering belt 6 is marked with pre-planned scales. Therefore, by observing the scales corresponding to the boundary between the plugging liquid and the metering liquid in the first metering tube 61 and the second metering tube 62, the measurement value can be quickly read.

[0074] It should be noted that the metering belt 6 in the present invention is made of a transparent material, which can directly observe the change of the boundary position between the metering liquid and the plugging liquid. At the same time, in other embodiments of the present application, a sliding-sealed partition can also be installed at the boundary between the plugging liquid and the metering liquid, which can not only be used to separate the plugging liquid and the metering liquid, but also facilitate observing the position where the metering liquid and the plugging liquid meet.

[0075] At the same time, the scales on the metering belt 6 in the present invention are marked during the manufacture of the geological compass. When marking, according to the change of the pressure value in the first capacity tube 64 and the second capacity tube 65, which causes the change of the boundary position between the plugging liquid and the metering liquid, the position and the pressure value are converted, and the corresponding scales can be engraved on the metering belt 6 for subsequent direct observation. And due to the existence of the expansion ball 63, it can not only provide a place for the discharge of the plugging liquid, but also use the pressure when the expansion ball 63 expands to provide power for the plugging liquid to push the metering liquid to flow back and reset. When the pressure in the first capacity tube 64 and the second capacity tube 65 is withdrawn, it is convenient for the plugging liquid and the metering liquid to flow back.

[0076] The first conversion assembly includes:

[0077] A conversion rod 7, the conversion rod 7 is fixedly installed on the top cover 11, the conversion rod 7 is arranged coaxially with the rotating shaft 2, and a spiral groove is provided on the conversion rod 7;

[0078] A driving member 71, the first capacitive tube 64 is fixedly installed in the rotating groove 21, the driving member 71 is slidably and sealingly installed in the first capacitive tube 64, and the driving member 71 extends into the rotating groove 21 and is in screw drive connection with the conversion rod 7.

[0079] In the present invention, the first rotating ring assembly is used to convert the change in the angle between the top cover 11 and the chassis 1 into the change in the pressure of the first capacitive tube 64. Specifically, when the braking mechanism relaxes the pressing on the brake pads, the rotating shaft 2 can rotate freely at this time. When the staff fits the top cover 11 on the rock formation to measure the dip angle, according to the specifications of the measurement process, the angle between the top cover 11 and the chassis 1 changes. At this time, the conversion rod 7 follows the top cover 11 and the driving member 71 follows the chassis 1, so that the conversion rod 7 and the driving member 71 generate relative rotation. Since the conversion rod 7 and the driving member 71 are in screw drive, the rotation is changed into a linear motion, causing the driving member 71 to move into the first capacitive tube 64, thereby pressing the metering liquid in the first capacitive tube 64, causing the metering liquid to move into the first metering tube 61 and pushing the sealing liquid to flow into the expansion ball 63, thereby changing the position of the interface between the metering liquid and the sealing liquid. When the brake pads brake the rotating shaft 2 again, the relative positions of the top cover 11 and the chassis 1 are fixed at this time. By observing the scale corresponding to the interface between the metering liquid and the sealing liquid, the angle between the top cover 11 and the chassis 1 can be read, and finally it is converted into the dip angle. When the measurement is over and the geological compass is closed, the driving member 71 is reset at this time. Under the tendency of the expansion ball 63 to return to its original state, the sealing liquid and the metering liquid flow back, so that the interface between the sealing liquid and the metering liquid returns to the initial scale.

[0080] The second conversion assembly includes:

[0081] A pull plate 72, the second capacitive tube 65 is designed in an arc shape, the second capacitive tube 65 is fixedly installed on the brake ring 33, the pull plate 72 is elastically installed in the second capacitive tube 65 through a return spring 73, and the transmission rope 43 corresponding to the brake ring 33 is fixedly connected to the pull plate 72;

[0082] An arc-shaped tube 74 and an arc-shaped piece 75, the arc-shaped tube 74 is fixedly installed on the inner wall of the brake ring 33, the arc-shaped tube 74 is in conduction connection with the second capacitive tube 65, the arc-shaped piece 75 is slidably installed in the arc-shaped tube 74, and the magnetic needle 25 is located on the movement path of the arc-shaped piece 75.

[0083] In the present invention, the second conversion component is used to convert the rotation angle of the magnetic needle 25 into a change in pressure within the second volumetric tube 65. Specifically, when the pressing member 4 is pressed, the braking ring 33 moves into the lifting groove 34. During this process, the pressing member 4 pulls the transmission rope 43, and the transmission rope 43 pulls the pull plate 72. Since the elastic force of the return spring 73 is less than the elastic force of the lifting spring 35, supported by the lifting spring 35 within the lifting groove 34, the pull plate 72 moves downward within the second volumetric tube 65, causing the measuring liquid in the arc-shaped tube 74 and the second metering tube 62 to flow back into the second volumetric chamber. At this time, the arc-shaped piece 75 completely contracts into the arc-shaped tube 74, the expansion ball 63 contracts, and the interface between the measuring liquid and the sealing liquid in the second metering tube 62 is at the initial scale position. Subsequently, the braking ring 33 compresses the lifting spring 35 and moves into the lifting groove 34. Then, after the measurement is completed, the pressing member 4 releases the pull on the braking ring 33. Under the elastic action of the spring within the lifting groove 34, the braking ring 33 first moves upward to fix the magnetic needle 25. Subsequently, under the action of the return spring 73, the pull plate 72 exerts pressure on the measuring liquid in the second volumetric tube 65, causing the measuring liquid to flow towards the arc-shaped tube 74. When the arc-shaped piece 75 moves to one side of the magnetic needle 25 under the push of the measuring liquid, due to the obstruction of the magnetic needle 25, the arc-shaped piece 75 cannot continue to move. At this time, the pull piece continues to reset and pushes the measuring liquid into the second metering tube 62, causing the sealing liquid to move into the expansion ball 63. The expansion ball 63 expands under pressure. At this time, the scale corresponding to the interface between the measuring liquid and the sealing liquid is the measured value of the magnetic needle 25.

[0084] As a preferred embodiment of the present invention, a spiral groove 8 is provided on one side of the chassis 1 away from the top cover 11, and the metering tape 6 is accommodated in the spiral groove 8.

[0085] One end of the metering tape 6 away from the chassis 1 is fixedly installed with a magnifying shell 81, and the magnifying shell 81 is made of a transparent material that is thick in the middle and thin at both ends.

[0086] The provision of the spiral groove 8 facilitates the accommodation of the metering tape 6, while the magnifying shell 81 that is thick in the middle and thin at both ends acts as a magnifying glass for magnifying and displaying the scale, facilitating the exploration personnel to observe the interface position between the sealing liquid and the measuring liquid.
