Description

Technical Field

[0001] This invention relates to the field of power engineering measurement technology, specifically to a power engineering field surveying device. Background Technology

[0002] On-site surveying for power engineering is the foundation for power grid planning, construction, and operation and maintenance. Traditional methods rely on equipment such as total stations to collect data manually, which is inefficient and risky. Modern technology has integrated UAV oblique photography, lidar, and BeiDou high-precision positioning to quickly obtain three-dimensional real-scene models and accurate coordinates, enabling automatic line design, accurate calculation of engineering quantities, and digital management of construction progress, which greatly improves work efficiency and safety.

[0003] Patent CN218066495U discloses a field surveying device for power engineering, relating to the field of power engineering technology. It includes a sealed box and a cover. The sealed box has a telescopic tube installed internally via a damping shaft. Inserting a telescopic rod into the telescopic tube, and with the cover in place, the storage tube can be stored, making it easy to carry. During surveying, a snap-fit ​​mechanism secures it to the power line for fixed use at heights. When used on the ground, the support rods on both sides extend to form a stable support with the sealed box, enabling surveying operations. It provides stable lateral support for surveying, making operation more convenient. To make it more convenient, when accurate target measurement is required during application, the buckle is fastened into the slot on the wheel. By holding the sealed box, the wheel rolls along the ground to be surveyed, driving the wheel to rotate and thus rotating the measuring tape in the storage tube. The data from the measuring tape can be used to achieve accurate ground mapping, making the mapping more standardized. Although this device solves the above problems, it still has the problem of a limited range of measuring objects, making it difficult to adapt to the complex environment of power engineering sites. At the same time, there is also the problem of too many measuring tools in power engineering sites, which are difficult to manage and easily lead to the loss of measuring tools. Therefore, a power engineering site surveying device is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a field surveying device for power engineering, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a field surveying device for power engineering, including a foot support plate, a foot frame fixedly connected to the bottom of the foot support plate, a fixed column fixedly connected to the top of the foot support plate, a fixed frame fixedly connected to the top of the fixed column, a horizontal calibration mechanism provided at the bottom of the foot support plate, a multi-effect measuring mechanism provided at the top of the fixed frame, an aperture measuring mechanism provided at the top of the foot support plate, and a fixed claw rod provided at the top of the foot support plate; The horizontal calibration mechanism includes a circular groove, a sliding column, a conductive wire, and a connecting cone. The circular groove is fixedly connected to the bottom of the foot plate, the sliding column is slidably connected to the inner wall of the circular groove, the conductive wire is fixedly connected to the bottom of the sliding column, and the connecting cone is fixedly connected to the bottom of the conductive wire.

[0006] Preferably, the horizontal calibration mechanism further includes a line projector, a light source port, a setting slot, and a top vertical chamber. The line projector is rotatably connected to the inner wall of the fixed frame, the light source port is fixedly connected to the outer wall of the line projector, the setting slot is opened on the inner wall of the line projector, and the top vertical chamber is fixedly connected to the top of the line projector.

[0007] Preferably, the horizontal calibration mechanism further includes a protective plate, a gravity block, a rotating gear, and a transmission rack. The protective plate is slidably connected to the inner wall of the projector, the gravity block is slidably connected to the inner wall of the top vertical chamber, the rotating gear is rotatably connected to the bottom of the gravity block, and the transmission rack is fixedly connected to the top of the protective plate. The transmission rack meshes with the rotating gear, and the slot is located on the movement trajectory of the protective plate. When using the device, first place it in a suitable position, then unfold the tripod and place it on a flat ground. Next, calibrate the device. During calibration, adjust the bending angle and length of the tripod, and observe the vertical angle between the connecting cone and the ground to assist in horizontal calibration. When the connecting cone swings, it causes the sliding column to slide inside the groove. When the connecting cone stops swinging and the scale on the circumference of the sliding column is perpendicular to the ground, the calibration is complete, ensuring the accuracy of subsequent measurements. Then, start the laser projector to project a baseline for laser measurement and data collection on the wall at the engineering site. When used outdoors, rotate the knob to rotate the laser projector. During rotation, as the laser projector rotates, the light source port points upwards for measurement. The gravity block slides backward, causing the bottom rotating gear to move. During this movement, the rotating gear engages, driving the transmission rack forward. The forward movement of the transmission rack causes the protective plate to pop out through the slot, thus preventing dust and sand from entering the laser projector and reducing interference from strong light on the light source port receiver. This, to a certain extent, protects the laser emitting element at the power engineering site.

[0008] Preferably, the multi-effect measuring mechanism further includes a counterweight, a measuring needle, and a scale plate. The counterweight is fixedly connected to the top of the gravity block, the measuring needle is fixedly connected to the top of the gravity block, and the scale plate is fixedly connected to the top of the top vertical compartment.

[0009] Preferably, the multi-effect measuring mechanism further includes a bottom solid chamber, a second transmission gear, and a horizontal scale. The bottom solid chamber is fixedly connected to the bottom of the line projector, the second transmission gear is rotatably connected to the inner wall of the bottom solid chamber, and the horizontal scale is fixedly connected to the outer wall of the bottom solid chamber.

[0010] Preferably, the multi-effect measuring mechanism further includes a first telescopic plate, a second telescopic plate, and a pull buckle. The first telescopic plate is slidably connected to the inner wall of the bottom solid chamber, the second telescopic plate is slidably connected to the inner wall of the bottom solid chamber, the pull buckle is fixedly connected to the outer wall of the second telescopic plate, the second transmission gear meshes with the second telescopic plate, and the first telescopic plate meshes with the second transmission gear. When in use, the projector can be removed and placed on the plane of the power engineering material that needs to be measured for horizontal reference. Then, the tilt angle of the plane drives the counterweight to slide under the limit of the top vertical compartment. The sliding of the counterweight causes the gravity block to slide, and the sliding of the gravity block causes the measuring needle to move. When the measuring needle stops moving, it points to the angle value on the scale plate, thus completing the tilt measurement of the engineering part. This allows the device to verify the installation accuracy of the equipment after it has been installed on the electrical engineering site, without the need to switch measuring instruments, thus improving the efficiency of engineering surveying. When it is necessary to measure some small parts on the power engineering site, pull the latch to engage the transmission gear two to make it rotate. The rotation of the transmission gear two engages the transmission to drive the telescopic plate one to extend. Then, the horizontal scale of the telescopic plate one and the outer wall of the bottom solid compartment is read to determine the length of the small electrical part. This allows workers to measure the engineering site without carrying a lot of measuring instruments, avoiding the loss of instruments due to the complexity of measuring tools on site, and can adapt to various measuring occasions, improving the convenience of on-site operations.

[0011] Preferably, the aperture measuring mechanism further includes a knob, a bidirectional screw, and a convergent L-shaped rod. The bidirectional screw is rotatably connected to the inner wall of the line projector, the knob is fixedly connected to the right end of the bidirectional screw, and the convergent L-shaped rod is threadedly connected to the outer circumferential surface of the bidirectional screw.

[0012] Preferably, the aperture measuring mechanism further includes a probe, a limiting slide bar, and a limiting button. The probe is fixedly connected to the top of the converging L-bar, the limiting slide bar is slidably connected to the inner wall of the converging L-bar, and the limiting button is fixedly connected to the outer wall of the limiting slide bar.

[0013] Preferably, the aperture measuring mechanism further includes an aperture scale, an isolation plate, a rotating disk, and an inclined sweeping rod. The aperture scale is formed on the outer wall of the limiting slide rod. The isolation plate is fixedly connected to the bottom of the transmission gear two. The rotating disk is fixedly connected to the bottom of the isolation plate. The inclined sweeping rod is fixedly connected to the outer circumferential surface of the rotating disk. During the measurement process, the line projector is removed, and the probe is inserted into the hole to be measured. Then, the knob is rotated to drive the bidirectional screw to rotate. During the rotation of the bidirectional screw, the spiral groove on the circumferential surface drives the convergent L-rod to unfold outward under the limit of the hole scale. During the outward unfolding of the convergent L-rod, the probe unfolds outward. When the probe contacts the outer wall of the hole, the hole diameter can be obtained by reading the hole scale on the circumferential surface of the limit slide. Thus, the dimensional measurement work of electrical engineering measurement can be completed in one stop, eliminating the error and efficiency loss of tool switching. Before measuring the part, the bottom fixing chamber is placed on the workpiece to be measured. Pulling the buckle drives the transmission gear two to rotate. The rotation of the transmission gear two drives the rotating disk to rotate. The rotation of the rotating disk drives the oblique sweeping rod to rotate. During the rotation of the oblique sweeping rod, the dust and electrical slag on the surface of the workpiece are swept away, so as to avoid impurities affecting the accuracy of the length and level measurement of the device.

[0014] The present invention, by adopting the above technical solution, can bring the following beneficial effects: This power engineering field surveying device, through the coordinated operation of a protective plate, a top vertical chamber, a sliding column, and a tripod, adjusts the bending angle and length of the tripod during calibration. It then assists in horizontal calibration by observing the perpendicular angle between the connecting cone and the ground. When the connecting cone swings, it causes the sliding column to slide within a circular groove. Calibration is complete when the connecting cone stops swinging and the scale on the sliding column's circumference is perpendicular to the ground, ensuring the accuracy of subsequent measurements. The tilt angle of the plane causes a counterweight to slide within the limit of the top vertical chamber. This counterweight movement causes a gravity block to slide, which in turn moves the measuring needle. When the measuring needle stops moving, it points to the angle value on the scale, thus measuring the tilt of the engineering components. This allows the device to verify the installation accuracy of electrical engineering equipment after installation, eliminating the need to switch measuring instruments and improving surveying efficiency.

[0015] 2. This power engineering field surveying device, through the cooperation of the transmission rack, transmission gear two, telescopic plate one, and the slot, allows the gravity block to slide backward, subsequently driving the rotating gear one at the bottom to move. During this movement, the rotating gear one engages and drives the transmission rack forward, which in turn causes the protective plate to pop out through the slot, thus preventing dust and sand from entering the inside of the projector and reducing interference from strong light on the receiving end of the light source. This provides a certain degree of protection for the laser emitting element at the power engineering site. When it is necessary to measure some small parts at the power engineering site, pulling the latch engages the transmission gear two, causing it to rotate. The rotation of the transmission gear two engages and drives the telescopic plate one to extend. Then, the transverse scale of the telescopic plate one and the outer wall of the bottom solid chamber is read to determine the length of the small electrical parts. This eliminates the need for workers to carry a large number of measuring instruments to measure the project site, avoiding the loss of instruments due to the complexity of the measuring tools and adapting to various measuring situations, thus improving the convenience of on-site operations.

[0016] 3. This power engineering field surveying device, with the cooperation of a bidirectional screw, a limiting slide bar, and a convergent L-bar, allows for the removal of the line projector during measurement. The probe is then inserted into the desired hole diameter. Rotating the knob drives the bidirectional screw, which, through its spiral groove on the circumferential surface, causes the convergent L-bar to extend outwards under the limitation of the hole scale. This outward extension of the convergent L-bar causes the probe to extend outwards as well. Once the probe contacts the outer wall of the hole, the hole diameter can be determined by reading the hole scale on the circumferential surface of the limiting slide bar. This allows for one-stop completion of dimensional measurement work in electrical engineering field surveying, eliminating errors and efficiency losses associated with tool switching.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-8 One embodiment of the present invention is: a field surveying device for power engineering, including a foot support plate 1, a foot frame 2 fixedly connected to the bottom of the foot support plate 1, a fixed column 3 fixedly connected to the top of the foot support plate 1, a fixed frame 4 fixedly connected to the top of the fixed column 3, a horizontal calibration mechanism 5 provided at the bottom of the foot support plate 1, a multi-effect measuring mechanism 6 provided at the top of the fixed frame 4, an aperture measuring mechanism 7 provided at the top of the foot support plate 1, and a fixed claw rod 8 provided at the top of the foot support plate 1; The horizontal calibration mechanism 5 includes a circular groove 501, a sliding column 502, a conductive wire 503, and a connecting cone 504. The circular groove 501 is fixedly connected to the bottom of the foot plate 1, the sliding column 502 is slidably connected to the inner wall of the circular groove 501, the conductive wire 503 is fixedly connected to the bottom of the sliding column 502, and the connecting cone 504 is fixedly connected to the bottom of the conductive wire 503.

[0021] The horizontal calibration mechanism 5 also includes a projector 505, a light source port 506, a slot 507, and a top vertical chamber 508. The projector 505 is rotatably connected to the inner wall of the fixed frame 4, the light source port 506 is fixedly connected to the outer wall of the projector 505, the slot 507 is opened on the inner wall of the projector 505, and the top vertical chamber 508 is fixedly connected to the top of the projector 505.

[0022] The horizontal calibration mechanism 5 also includes a protective plate 509, a gravity block 510, a rotating gear 511, and a transmission rack 512. The protective plate 509 is slidably connected to the inner wall of the projector 505, the gravity block 510 is slidably connected to the inner wall of the top vertical chamber 508, the rotating gear 511 is rotatably connected to the bottom of the gravity block 510, and the transmission rack 512 is fixedly connected to the top of the protective plate 509. The transmission rack 512 meshes with the rotating gear 511, and the slot 507 is located on the movement trajectory of the protective plate 509. This power engineering field surveying device, during calibration, adjusts the bending angle and length of the tripod 2, and then observes the vertical angle between the connecting cone 504 and the ground to assist in the horizontal calibration of the device. When the connecting cone 504 swings, it causes the sliding column 502 to slide inside the circular groove 501. When the connecting cone 504 stops swinging and the scale on the circumference of the sliding column 502 is perpendicular to the ground, the device is calibrated, thus ensuring the accuracy of subsequent measurements. The tilt angle of the plane causes the counterweight 601 to slide under the limit of the top vertical compartment 508. The sliding of the counterweight 601 causes the gravity block 510 to slide, and the sliding of the gravity block 510 causes the measuring needle 602 to move. When the measuring needle 602 stops moving, it points to the angle value on the scale plate 603, thus completing the tilt measurement of the engineering parts. This allows the device to verify the installation accuracy of electrical engineering field equipment after installation, without the need to switch measuring instruments, thereby improving the efficiency of engineering surveying.

[0023] The multi-effect measuring mechanism 6 also includes a counterweight 601, a measuring needle 602, and a scale plate 603. The counterweight 601 is fixedly connected to the top of the gravity block 510, the measuring needle 602 is fixedly connected to the top of the gravity block 510, and the scale plate 603 is fixedly connected to the top of the top vertical compartment 508.

[0024] The multi-effect measuring mechanism 6 also includes a bottom solid chamber 604, a transmission gear 605, and a transverse scale 606. The bottom solid chamber 604 is fixedly connected to the bottom of the line projector 505, the transmission gear 605 is rotatably connected to the inner wall of the bottom solid chamber 604, and the transverse scale 606 is fixedly connected to the outer wall of the bottom solid chamber 604.

[0025] The multi-effect measuring mechanism 6 also includes a telescopic plate 607, a telescopic plate 608, and a buckle 609. The telescopic plate 607 is slidably connected to the inner wall of the bottom solid chamber 604, the telescopic plate 608 is slidably connected to the inner wall of the bottom solid chamber 604, and the buckle 609 is fixedly connected to the outer wall of the telescopic plate 608. The transmission gear 605 meshes with the telescopic plate 608, and the telescopic plate 607 meshes with the transmission gear 605. This power engineering field surveying device uses a gravity block 510 that slides backward, causing the rotating gear 511 at the bottom to move. During this movement, the rotating gear 511 engages with the transmission rack 512, which moves forward. The forward movement of the transmission rack 512 causes the protective plate 509 to pop out through the slot 507, thus preventing dust and sand from entering the inside of the line projector 505 and reducing interference from strong light on the receiving end of the light source port 506. This provides some protection for the laser emitting element at the power engineering site. When it is necessary to measure some small parts at the power engineering site, the pull buckle 609 engages with the transmission gear 605, causing it to rotate. The rotation of the transmission gear 605 engages with the telescopic plate 607, which extends. The length of the small electrical parts is then determined by reading the transverse scale 606 between the telescopic plate 607 and the outer wall of the bottom solid chamber 604. This eliminates the need for workers to carry a large number of measuring instruments at the engineering site, avoiding the loss of instruments due to the complexity of the measuring tools and improving the convenience of on-site operations in various measurement situations.

[0026] Working Principle: When using the device, first place it in a suitable position, then unfold the tripod 2 and place it on a flat surface. Next, calibrate the device. During calibration, adjust the bending angle and length of the tripod 2. Then, observe the perpendicular angle between the connecting cone 504 and the ground to assist in the horizontal calibration of the device. When the connecting cone 504 swings, it causes the sliding column 502 to slide inside the circular groove 501. When the connecting cone 504 stops swinging and the scale on the circumference of the sliding column 502 is perpendicular to the ground, the device calibration is complete, thus ensuring the accuracy of subsequent measurements. Then, activate the line projector 505 to project a baseline line for laser measurement of the wall surface at the construction site. Data collection: When used outdoors, rotating knob 701 causes the laser projector 505 to rotate. During the rotation of the laser projector 505, the light source port 506 is directed towards the top for measurement. Gravity block 510 slides backward, which in turn moves the rotating gear 511 at the bottom. During the movement, the rotating gear 511 engages and drives the transmission rack 512 forward. The forward movement of the transmission rack 512 causes the protective plate 509 to pop out through the slot 507, thereby preventing dust and sand from entering the interior of the laser projector 505 and reducing the interference of strong light on the receiving end of the light source port 506. To a certain extent, this protects the laser emitting element at the power engineering site.

[0027] When in use, the line projector 505 can be removed and placed on the flat surface of the electrical engineering material requiring horizontal reference. The tilt angle of the surface then causes the counterweight 601 to slide under the limit of the top vertical compartment 508. The sliding of the counterweight 601 causes the gravity block 510 to slide, which in turn moves the measuring needle 602. When the measuring needle 602 stops moving, it points to the angle value on the scale plate 603, thus completing the tilt measurement of the engineering part. This allows the device to verify the installation accuracy of electrical engineering equipment after installation on-site, eliminating the need for manual measurement. Additional measuring instruments are required to improve engineering surveying efficiency. When it is necessary to measure some small parts at the power engineering site, pull the buckle 609 to engage the transmission gear 605 to make it rotate. The rotation of the transmission gear 605 engages the transmission to drive the telescopic plate 607 to extend. Then, read the transverse scale 606 between the telescopic plate 607 and the outer wall of the bottom solid chamber 604 to know the length of the small electrical parts. This allows workers to measure the engineering site without holding a lot of measuring instruments, avoiding the loss of instruments due to the complexity of measuring tools at the site, and can also adapt to various measuring occasions to improve the convenience of on-site operations.

[0028] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the aperture measuring mechanism 7 further includes a knob 701, a bidirectional screw 702, and a convergent L-shaped rod 703. The bidirectional screw 702 is rotatably connected to the inner wall of the line projector 505, the knob 701 is fixedly connected to the right end of the bidirectional screw 702, and the convergent L-shaped rod 703 is threadedly connected to the outer circumferential surface of the bidirectional screw 702.

[0029] The aperture measuring mechanism 7 also includes a probe 704, a limiting slide bar 705, and a limiting button 706. The probe 704 is fixedly connected to the top of the gathering L-bar 703, the limiting slide bar 705 is slidably connected to the inner wall of the gathering L-bar 703, and the limiting button 706 is fixedly connected to the outer wall of the limiting slide bar 705.

[0030] The aperture measuring mechanism 7 also includes an aperture scale 707, an isolation plate 708, a rotating disk 709, and an inclined sweeping rod 710. The aperture scale 707 is opened on the outer wall of the limiting slide rod 705. The isolation plate 708 is fixedly connected to the bottom of the transmission gear 605. The rotating disk 709 is fixedly connected to the bottom of the isolation plate 708. The inclined sweeping rod 710 is fixedly connected to the outer circumferential surface of the rotating disk 709. This power engineering field surveying device allows for the removal of the line projector 505 during measurement. The probe 704 is then inserted into the desired hole diameter. Rotating the knob 701 drives the bidirectional screw 702 to rotate. During rotation, the screw 702, through its spiral groove on the circumferential surface, causes the convergent L-shaped rod 703 to extend outwards under the limit of the hole scale 707. This outward extension of the convergent L-shaped rod 703 also causes the probe 704 to extend outwards. Once the probe 704 contacts the outer wall of the hole, the hole diameter can be determined by reading the hole scale 707 on the circumferential surface of the limit slide rod 705. This allows for one-stop multi-dimensional measurement of electrical engineering field work, eliminating errors and efficiency losses associated with tool switching.

[0031] Working principle: During the measurement process, the line projector 505 is removed, and then the probe 704 is inserted into the hole to be measured. The knob 701 is then rotated, causing the bidirectional screw 702 to rotate. During rotation, the bidirectional screw 702, through the spiral groove on its circumferential surface, drives the convergent L-shaped rod 703 to extend outwards under the limit of the hole scale 707. As the convergent L-shaped rod 703 extends outwards, it also drives the probe 704 to extend outwards. When the probe 704 contacts the outer wall of the hole, the hole diameter can be determined by reading the hole scale 707 on the circumferential surface of the limiting slide rod 705. It can complete multi-dimensional measurement work on the electrical engineering measurement site in one stop, eliminating the error and efficiency loss of tool switching. Before measuring the part, the bottom solid chamber 604 is placed on the workpiece to be measured. Pulling the buckle 609 drives the transmission gear 605 to rotate. The rotation of the transmission gear 605 drives the rotating disk 709 to rotate. The rotation of the rotating disk 709 drives the inclined sweeping rod 710 to rotate. During the rotation of the inclined sweeping rod 710, the dust and electrical slag on the surface of the workpiece are swept away, so as to avoid impurities affecting the accuracy of the length and level measurement of the device.
