Abstract
Description
Technical Field
[0001] This utility model relates to the field of surveying equipment technology, specifically to a land surveying equipment for water conservancy projects that is easy to adjust. Background Technology
[0002] Land surveying is integral to the entire construction cycle of water conservancy projects. For example, before construction, surveys identify fault zones, landslides, and karst development areas to mitigate geological disaster risks and ensure site safety. During construction, a construction control network is established to ensure the positioning accuracy of structures; the terrain is monitored in real time, and design deviations are dynamically corrected by periodically re-measuring excavation volume and backfill compaction. After construction, displacement observation points are installed, and periodic measurements are used to provide early warnings of abnormal structural deformation; combined with geological maps and hydrological monitoring data, seepage channels are located, and anti-seepage reinforcement plans are developed.
[0003] Total stations are commonly used surveying equipment in land surveying. To better suit users of different heights, existing total stations employ a coarse-fine adjustment process. Specifically, coarse adjustment involves adjusting the height of the total station's support, while fine adjustment involves adjusting the height of the total station's base.
[0004] The existing total station base is adjusted by threaded connection, which requires staff to repeatedly turn knobs and other equipment to adjust the height, making the operation relatively cumbersome and inconvenient. Utility Model Content
[0005] The technical problem to be solved by this utility model is that the existing total station base is adjusted by threaded connection. The purpose is to provide a land surveying device for water conservancy projects that is easy to adjust, so as to solve the above-mentioned problem.
[0006] This utility model is achieved through the following technical solution:
[0007] A land surveying device for water conservancy projects that is easy to adjust includes a support, a base and a surveying instrument connected in sequence, with the base and the surveying instrument connected by an adjustment module;
[0008] The adjustment module includes a slide with an inclined surface, on which the surveyor is slidably mounted and can slide back and forth along the inclined surface to adjust the height of the surveyor.
[0009] The adjustment module also includes a locking component and a control component set on the slide. The locking component is used to fix the surveyor at a certain height, and the control component is used to control whether the locking component fixes the surveyor.
[0010] In one possible design, the slide table is provided with a groove parallel to the inclined plane, and the lower end of the surveyor is inserted into the groove, so that the surveyor can slide along the groove.
[0011] The locking element is slidably mounted on the slide table and located outside the slide groove. The locking element fixes the position of the surveyor by pressing against it.
[0012] The control component is slidably mounted on the slide. The control component slides in a first direction to disengage the locking component from the surveyor, and slides in a second direction to press the locking component against the surveyor. Accordingly, the first direction and the second direction are opposite to each other.
[0013] In one possible design, there is one or two locking elements;
[0014] Accordingly, when a locking element is provided, the locking element is located on one side of the slide, and the locking element presses against the side wall of the slide to fix the position of the detector;
[0015] Correspondingly, when there are two locking elements, the two locking elements are located on both sides of the slide groove, and the two locking elements press against and clamp the surveyor to fix the position of the surveyor.
[0016] In one possible design, the locking element includes a slide, a pressure block, and a spring;
[0017] The slide is mounted on the slide platform. The slide has two opposing outer surfaces, one of which faces the slide groove and is equipped with a pressure block, and the other faces away from the slide groove and is connected to a spring.
[0018] Accordingly, several pressure blocks are provided and are equally spaced along the length of the slide plate, and springs are used to provide elastic force so that the slide plate presses against the surveyor through the pressure blocks.
[0019] In one possible design, the lower end of the surveyor is provided with a deformation layer. Accordingly, when the slide plate presses against the surveyor by the pressure block, the deformation layer is deformed by pressure. Furthermore, the length of the lower end of the surveyor is greater than the sum of the widths of the two pressure blocks and their spacing.
[0020] In one possible design, the lower end of the slide is constructed as a downwardly extending attachment, through which the slide abuts against the control element. Accordingly, the control element drives the slide to move away from the surveyor via the attachment.
[0021] In one possible design, the control components include a baffle, a stop plate, and a control lever;
[0022] A baffle is fixedly mounted on the slide table, and at least one abutment is provided and slidably mounted on the baffle. A control rod is slidably mounted on the baffle and hinged to the abutment via a hinge rod. One end of the control rod extends out of the slide table. Correspondingly, one end of the abutment is hinged to the hinge rod, and the other end of the abutment abuts against an additional part of the slide plate.
[0023] When the control lever slides in the first direction, the hinge lever rotates and drives the stop plate to move outward, thereby driving the slide plate away from the surveyor. When the control plate slides in the second direction, the hinge lever rotates and drives the stop plate to retract inward, so that the slide plate is reset under the action of the spring.
[0024] In one possible design, when there is one locking element, there is one abutment plate, and correspondingly, there is one hinge rod; when there are two locking elements, there are two abutment plates located on both sides of the control rod, and correspondingly, there are two hinge rods.
[0025] In one possible design, the adjustment module also includes an adjustment box, which is mounted on the base, with the slide table located inside the adjustment box, and the control lever of the control component extending outside the adjustment box.
[0026] In one possible design, a tripod is used as the support.
[0027] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0028] By replacing the threaded connection in the existing technology with an adjustment module, the height of the surveyor can be adjusted by reciprocating sliding along the inclined slide, eliminating the need for repeated screwing to adjust the height of the surveyor, reducing operation time, and improving the convenience of operation, making adjustment more convenient, efficient and simple.

Detailed Implementation
[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.
[0037] Example:
[0038] like Figures 1-4 As shown, a land surveying device for water conservancy projects that is easy to adjust includes a support 100, a base 200 and a surveyor 300 connected in sequence. The base 200 and the surveyor 300 are connected by an adjustment module 400.
[0039] The adjustment module 400 includes a slide table 1 with an inclined surface. The surveyor 300 is slidably mounted on the slide table 1 and can slide back and forth along the inclined surface to adjust the height of the surveyor 300.
[0040] The adjustment module 400 also includes a locking element 2 and a control element 3 disposed on the slide table 1. The locking element 2 is used to fix the surveyor 300 to a certain height, and the control element 3 is used to control whether the locking element 2 fixes the surveyor 300.
[0041] The surveyor 300 is connected to the adjustment module 400 via the slide table 1. If the height of the surveyor 300 needs to be adjusted, the locking member 2 is released by the operation control component 3, and the surveyor 300 can move back and forth along the slide table 1 under the push of the operator, thereby adjusting the height of the surveyor 300. Correspondingly, when the height of the surveyor 300 is adapted to the height of the operator, the locking member 2 can be fixed to the surveyor 300 again by the operation control component 3.
[0042] Based on this, the adjustment module 400 replaces the threaded connection in the prior art, and the height of the surveyor 300 is adjusted by reciprocating sliding along the inclined slide 1. There is no need to repeatedly turn the screw to adjust the height of the surveyor 300, which reduces the operation time and improves the convenience of operation, making the adjustment more convenient, efficient and simple.
[0043] During operation, the staff moves the easily adjustable land surveying equipment for water conservancy projects to any suitable observation point, opens the support 100, and makes a coarse adjustment to the height. This point is the same as in existing technology and will not be described again here. After the coarse adjustment is completed, fine adjustment can be performed through the adjustment module 400. That is, by operating the control component 3 to release the locking component 2, the surveyor 300 can be moved back and forth along the slide table 1 by the staff until the surveyor 300 is at a suitable height. The control component 3 is then used to fix the position of the surveyor 300 again by the locking component 2. After the height is appropriate, the surveyor 300 can be leveled.
[0044] It is easy to understand that the surveying instrument 300 can be a total station or any other suitable existing surveying equipment, and this utility model does not impose any restrictions on it.
[0045] In one possible implementation, the slide table 1 is provided with a groove parallel to the inclined plane, and the lower end of the surveyor 300 is inserted into the groove, so that the surveyor 300 can slide along the groove.
[0046] The locking element 2 is slidably mounted on the slide table 1 and located outside the slide groove. The locking element 2 fixes the position of the detector 300 by pressing against the detector 300.
[0047] The control element 3 is slidably set on the slide table 1. The control element 3 slides in the first direction to disengage the locking element 2 from the surveyor 300. The control element 3 slides in the second direction to press the locking element 2 against the surveyor 300. Accordingly, the first direction and the second direction are opposite to each other.
[0048] Based on the above design, the locking element 2 applies pressure to the surveyor 300 by pressing against it. A single locking element 2 cooperates with the side wall of the slide, or two locking elements 2 cooperate with each other, thereby fixing the position of the surveyor 300. The control element 3 achieves control through reciprocating movement. For operators, its operation is simple—pushing and pulling—eliminating the need for repeated turning, making it convenient to use.
[0049] For the staff, they can push and pull the control piece 3 with one hand and slide the surveyor 300 with the other hand. When the surveyor 300 moves to the appropriate height, the height of the surveyor 300 can be fixed by the locking piece 2.
[0050] In one possible implementation, the locking element 2 is one or two;
[0051] Accordingly, when a locking element 2 is provided, the locking element 2 is located on one side of the slide groove, and the locking element 2 presses against the side wall of the slide groove to fix the position of the detector 300.
[0052] Correspondingly, when there are two locking elements 2, the two locking elements 2 are located on both sides of the slide groove, and the two locking elements 2 press against and clamp the surveyor 300 to fix the position of the surveyor 300.
[0053] Based on the above design scheme, one or two locking elements 2 can be set. A single locking element 2 cooperates with the side wall of the slide and clamps the surveyor 300. Two locking elements 2 are opposite to each other and clamp the surveyor 300, thereby fixing the position and height of the surveyor 300.
[0054] It is worth noting that, comparatively, the use of a single locking element 2 helps reduce structural complexity, lower economic costs, and decrease the failure rate, but the force required to fix the surveyor 300 is relatively small. Conversely, the structure of two locking elements 2 is more complex, with more moving parts, making them more prone to failure, but the force required to fix the surveyor 300 is relatively larger, resulting in better fixation. Therefore, operators can choose the number of locking elements 2 as needed.
[0055] Optionally, such as Figure 2 As shown, the locking component 2 includes a sliding plate 201, a pressure block 202, and a spring 203;
[0056] The slide plate 201 is slidably mounted on the slide table 1. The slide plate 201 has two opposing outer surfaces, one of which faces the slide groove and is provided with a pressure block 202, and the other faces away from the slide groove and is connected to a spring 203.
[0057] Accordingly, the pressure block 202 is provided with several and is equally spaced along the length of the slide plate 201, and the spring 203 is used to provide elastic force so that the slide plate 201 presses against the surveyor 300 through the pressure block 202.
[0058] Based on the above design, the slide plate 201 has an initial working position via the spring 203. Specifically, the slide plate 201 presses against the surveyor 300 via the pressure block 202. The pressure block 202 increases the coefficient of friction, concentrating the local stress between the slide plate 201 and the surveyor 300 to improve the pressing effect. Conversely, when the operator operates the control component 3, the slide plate 201 moves under external force until the pressure block 202 disengages from the surveyor 300, the spring 203 deforms, and the surveyor 300 can slide back and forth along the groove and adjust its height. When the operator resets the control component 3, the slide plate 201 resets under the elastic force of the spring 203 until the pressure block 202 presses against the surveyor 300, thus re-fixing the surveyor 300.
[0059] In one possible implementation, the lower end of the surveyor 300 is provided with a deformation layer. Accordingly, when the sliding plate 201 presses against the surveyor 300 via the pressure block 202, the deformation layer is deformed under pressure. Based on this, when the pressure block 202 presses against the surveyor 300, the deformation of the deformation layer appropriately increases the contact area, so that the deformation layer and the pressure block 202 form a barrier, preventing the surveyor 300 from sliding down due to gravity.
[0060] In one possible implementation, the length of the lower end of the surveyor 300 is greater than the sum of the widths of the two pressure blocks 202 and their spacing. Based on this, for the locking member 2 on the same side, it is ensured that at least two pressure blocks 202 simultaneously press against the surveyor 300, increasing the number of connection points and ensuring the pressing effect.
[0061] In one possible implementation, the lower end of the slide plate 201 is constructed as a downwardly extending attachment 204. The slide plate 201 abuts against the control member 3 via the attachment 204. Correspondingly, the control member 3 drives the slide plate 201 to move away from the surveyor 300 via the attachment 204. Based on the above design, the attachment 204 causes the main body of the locking member 2 to be misaligned with the control member 3. The main body of the locking member 2 is used to press against the surveyor 300. The attachment 204 is connected to the control member 3, thereby controlling the position of the locking member 2 via the control member 3.
[0062] For control element 3, optionally, such as Figure 3 and Figure 4 As shown, the control component 3 includes a baffle 301, a stop plate 302, and a control lever 303;
[0063] A baffle 301 is fixedly mounted on the slide table 1. At least one abutment 302 is provided and slidably mounted on the baffle 301. A control rod 303 is slidably mounted on the baffle 301 and hinged to the abutment 302 via a hinge rod 304. One end of the control rod 303 extends outside the slide table 1. Correspondingly, one end of the abutment 302 is hinged to the hinge rod 304, and the other end of the abutment 302 abuts against the additional part 204 of the slide plate 201.
[0064] When the control lever 303 slides along the first direction, the hinge lever 304 rotates and drives the abutment plate 302 to move outward, so as to drive the slide plate 201 away from the surveyor 300. When the control plate slides along the second direction, the hinge lever 304 rotates and drives the abutment plate 302 to retract, so that the slide plate 201 is reset under the action of the spring 203.
[0065] Based on the above design, the operator pushes the control lever 303 to move it in the direction of the baffle 301. The extreme position is reached when the hinge lever 304 rotates to be parallel to the baffle 301. At this point, if... Figure 4 As shown, the hinge rod 304 is tightly attached to the baffle 301. The hinge rod 304 rotates and pushes the abutment 302 to move. When the abutment 302 moves outward, it pushes the additional part 204 of the slide plate 201 to move, so that the slide plate 201 moves away from the surveyor 300, and the surveyor 300 can slide back and forth along the groove.
[0066] Conversely, when the operator pulls back the control lever 303, the hinge lever 304 resets and pulls the abutment plate 302 to retract. After losing external force, the locking piece 2 resets under the action of the elastic force until the pressure block 202 presses against the surveyor 300 again.
[0067] As is easily understood, the hinge rod 304 is connected to the control rod 303 via a torsion spring. When the control rod 303 is pulled back to its original position, the hinge rod 304 also returns to its original position under the force of the torsion spring. Simultaneously, when the operator does not operate the control rod 303, the force of the torsion spring can offset some of the external force, and it also cooperates with the spring 203 of the locking element 2 to prevent external disturbances from causing the surveyor 300 to move unexpectedly.
[0068] It is worth noting that when there is one locking element 2, there is one abutment plate 302, and correspondingly, there is one hinge rod 304; when there are two locking elements 2, there are two abutment plates 302 located on both sides of the control rod 303, and correspondingly, there are two hinge rods 304. Based on this, the locking element 2, abutment plate 302, and hinge rod 304 are arranged in a one-to-one correspondence, so the number of the three is also consistent.
[0069] In one possible implementation, the adjustment module 400 further includes an adjustment box 4, which is mounted on the base 200. The slide 1 is housed within the adjustment box 4, and the control lever 303 of the control component 3 extends beyond the adjustment box. Based on the above design, the adjustment box 4 provides a barrier, reducing the erosion of external impurities on components such as the slide 1, thereby improving the service life of these components.
[0070] As is easily understood, the adjustment box 4 is provided with a through groove adapted to the surveyor 300. The through groove is located above the slide groove. The surveyor 300 passes through the through groove and is inserted into the slide groove. When the surveyor 300 slides, it also slides along the through groove to avoid the adjustment box 4 blocking the surveyor 300.
[0071] In one possible implementation, the support 100 is a tripod. It is easy to understand that the support 100 can also be any other suitable existing support 100, which will not be elaborated here.
[0072] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
