Technical Field
[0001] This utility model relates to the field of water conservancy engineering, and in particular to a surveying instrument for water conservancy engineering that is easy to adjust. Background Technology
[0002] A surveying instrument is a professional instrument used to measure and map geospatial information, the shape and location of objects, and is widely used in fields such as engineering construction, geological exploration, water conservancy projects, and urban planning.
[0003] Existing hydraulic surveying instruments mostly adopt traditional tripod support structures, which have problems such as cumbersome deployment and storage operations and insufficient support stability. Especially when working in complex terrain, it is difficult to quickly adjust the support angle to adapt to the ground undulations. Secondly, the angle adjustment of the main body of the surveying instrument usually relies on complex hydraulic or electric devices, which are not only costly, but also easily affected by environmental factors during field operations, making adjustment difficult. Furthermore, the installation and disassembly process of the main body of the surveying instrument is cumbersome, often requiring the assistance of tools, which consumes a lot of time and manpower. In order to solve the above problems, we propose a surveying instrument for hydraulic engineering that is easy to adjust. Utility Model Content
[0004] The main purpose of this utility model is to provide a surveying instrument that is easy to adjust for use in water conservancy projects, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] An easily adjustable surveying instrument for water conservancy projects includes a circular plate. A support column is fixedly connected to the upper end of the circular plate. A rotating plate is rotatably connected to the upper end of the support column. Two snap-fit plates are fixedly connected to the upper end of the rotating plate. The main body of the surveying instrument is clamped between the two snap-fit plates. Multiple main support legs are rotatably connected to the outer side of the circular plate. A secondary support leg is fixedly connected to the lower end of each of the multiple main support legs. A storage sleeve is fixedly connected to the lower end of the circular plate. A limit component is provided on the outer side of the storage sleeve. A tension rod is slidably connected to the inner side of the storage sleeve. A gravity block is fixedly connected to the lower end of the tension rod. Multiple rotating rods corresponding to the main support legs are rotatably connected to the outer side of the gravity block. The other ends of the multiple rotating rods are rotatably connected to the corresponding main support legs.
[0007] Preferably, a rotating column is fixedly connected to the lower end of the rotating plate. The rotating column is located in the inner cavity of the support column. A first conical wheel is fixedly connected to the lower end of the rotating column. A second conical wheel is engaged with the outer side of the first conical wheel. The second conical wheel is rotatably connected to the support column. A manual wheel is fixedly connected to one side of the second conical wheel. The manual wheel is located on the outer side of the support column.
[0008] Preferably, the main body of the surveying instrument has slots on both sides, and each slot has a locking post on its inner side. The two locking posts are slidably connected to the corresponding main body of the surveying instrument. A pull plate is fixedly connected to the other end of the locking post. A spring is sleeved on the outer side of the locking plate, and the two ends of the spring are fixedly connected to the corresponding locking plate and the pull plate, respectively.
[0009] Preferably, the limiting component includes a mounting bracket, which is fixedly connected to the outside of the receiving sleeve column. A limiting rack is slidably connected to the inside of the mounting bracket. A limiting hole corresponding to the limiting rack is opened on the outside of the tension rod, and the limiting rack is adapted to the limiting hole.
[0010] Preferably, a gear is engaged on the outer side of the limiting rack, the gear is rotatably connected to the inner side of the mounting frame, and a knob is fixedly connected to one end of the gear, the knob being located on the outer side of the mounting frame.
[0011] Preferably, a plurality of first rotating seats corresponding to the main support leg are fixedly connected to the outer side of the circular plate, and the main support leg is rotatably connected to the outer side of the circular plate through the first rotating seats.
[0012] Preferably, a plurality of second rotating seats corresponding to the rotating rod are fixedly connected to the outer side of the gravity block, one end of the rotating rod is rotatably connected to the inner side of the second rotating seat, and a plurality of third rotating seats corresponding to the rotating rod are fixedly connected to the outer side of the main support leg, and the other end of the rotating rod is rotatably connected to the inner side of the third rotating seat.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. This is a water conservancy engineering surveying instrument that is easy to adjust. By rotating the knob, the gear is driven to rotate, which causes the limiting rack to disengage from the limiting hole of the tension rod. At this time, the gravity block slides down along the storage sleeve column under the action of gravity, so that the rotating rod pushes multiple main support legs to unfold outward synchronously, forming a triangular stable support structure. When storing, the reverse operation can be used to quickly fold it up, which changes the cumbersome adjustment method of the traditional tripod. At the same time, by rotating the manual wheel, and through the transmission cooperation of the first cone wheel and the second cone wheel, the rotating plate can drive the main body of the surveying instrument to rotate flexibly, and the measurement angle can be adjusted accurately and quickly.
[0015] 2. This type of easily adjustable surveying instrument for water conservancy projects allows for easy installation of the instrument body. By pulling the pull plate, the locking pins are retracted. Then, the instrument body is placed between the two locking plates and released. At this time, under the push of the spring force, the locking pins will lock into the slots on the outside of the instrument body to complete the fixation. Conversely, pulling the pull plate allows for quick removal of the instrument body, effectively saving manpower and time costs. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figure 1-5As shown, a surveying instrument for water conservancy projects that is easy to adjust includes a circular plate 1. A support column 12 is fixedly connected to the upper end of the circular plate 1. A rotating plate 13 is rotatably connected to the upper end of the support column 12. Two snap-fit plates 14 are fixedly connected to the upper end of the rotating plate 13. A surveying instrument body 15 is snapped between the two snap-fit plates 14. Multiple main support legs 3 are rotatably connected to the outer side of the circular plate 1. A secondary support leg 4 is fixedly connected to the lower end of the multiple main support legs 3. A storage sleeve column 5 is fixedly connected to the lower end of the circular plate 1. A limit component 11 is provided on the outer side of the storage sleeve column 5. A tension rod 6 is slidably connected to the inner side of the storage sleeve column 5. A gravity block 7 is fixedly connected to the lower end of the tension rod 6. Multiple rotating rods 9 corresponding to the main support legs 3 are rotatably connected to the outer side of the gravity block 7. The other end of the multiple rotating rods 9 is rotatably connected to the corresponding main support leg 3.
[0024] In this embodiment, a rotating column 19 is fixedly connected to the lower end of the rotating plate 13. The rotating column 19 is located in the inner cavity of the support column 12. A first conical wheel 20 is fixedly connected to the lower end of the rotating column 19. A second conical wheel 21 is engaged with the outer side of the first conical wheel 20. The second conical wheel 21 is rotatably connected to the support column 12. A manual wheel 22 is fixedly connected to one side of the second conical wheel 21. The manual wheel 22 is located on the outer side of the support column 12.
[0025] Specifically, when it is necessary to adjust the measurement angle, the second conical wheel 21 is rotated by rotating the manual wheel 22. Through the meshing transmission of the first conical wheel 20, the rotating column 19 can drive the rotating plate 13 and the main body of the surveying instrument 15 to rotate horizontally, so as to realize multi-angle measurement and adjustment.
[0026] In this embodiment, slots are provided on both sides of the main body 15 of the surveying instrument. A locking post 16 is provided on the inner side of each slot. The two locking posts 16 are slidably connected to the corresponding main body 15 of the surveying instrument. A pull plate 18 is fixedly connected to the other end of the locking post 16. A spring 17 is sleeved on the outer side of the locking plate 14. The two ends of the spring 17 are fixedly connected to the corresponding locking plate 14 and the pull plate 18, respectively.
[0027] Specifically, when installing the surveying instrument body 15, the locking pin 16 is retracted by pulling the pulling plate 18, and the surveying instrument body 15 is placed between the two locking plates 14 and then released. At this time, under the push of the spring force of the spring 17, the locking pin 16 will be locked into the slot on the outside of the surveying instrument body 15 to complete the fixation.
[0028] In this embodiment, the limiting component 11 includes a mounting frame 111, which is fixedly connected to the outside of the receiving sleeve column 5. A limiting rack 112 is slidably connected to the inside of the mounting frame 111. A limiting hole 115 corresponding to the limiting rack 112 is opened on the outside of the tension rod 6. The limiting rack 112 is adapted to the limiting hole 115. A gear 113 meshes with the outside of the limiting rack 112. The gear 113 is rotatably connected to the inside of the mounting frame 111. A knob 114 is fixedly connected to one end of the gear 113. The knob 114 is located on the outside of the mounting frame 111. A plurality of first rotating seats 2 corresponding to the main support leg 3 are fixedly connected to the outside of the circular plate 1. The main support leg 3 is rotatably connected to the outside of the circular plate 1 through the first rotating seats 2.
[0029] Specifically, rotating the knob 114 drives the gear 113 to rotate, which in turn causes the limiting rack 112 to disengage from the limiting hole 115 of the tension rod 6. At this time, the gravity block 7 slides down along the storage sleeve 5 under the action of gravity, so that the rotating rod 9 pushes the main support leg 3 and the support leg 4 to expand outward around the first rotating seat 2 in a synchronous manner to form a triangular support structure. Similarly, when it needs to be stored, by pushing the gravity block 7 upward, the rotating rod 9 drives the main support leg 3 to retract towards the circular plate 1. At this time, rotating the knob 114 in the opposite direction causes the limiting rack 112 to re-engage into the limiting hole 115 to lock the tension rod 6.
[0030] In this embodiment, multiple second rotating seats 8 corresponding to the rotating rod 9 are fixedly connected to the outer side of the gravity block 7. One end of the rotating rod 9 is rotatably connected to the inner side of the second rotating seat 8. Multiple third rotating seats 10 corresponding to the rotating rod 9 are fixedly connected to the outer side of the main support leg 3. The other end of the rotating rod 9 is rotatably connected to the inner side of the third rotating seat 10.
[0031] Specifically, the design of the second rotating seat 8 and the third rotating seat 10 allows the rotating rod 9 to easily rotate and push / pull the main support leg 3, thereby enabling the main support leg 3 to unfold or retract.
[0032] It should be noted that this utility model is a surveying instrument for easy adjustment in water conservancy engineering. First, the surveying instrument is moved to the measurement position. Then, the knob 114 is rotated to drive the gear 113 to rotate, causing the limiting rack 112 to disengage from the limiting hole 115 of the tension rod 6. At this time, the gravity block 7 slides down along the storage sleeve 5 under the action of gravity, realizing that the rotating rod 9 pushes the main support leg 3 and the support leg 4 to expand outward around the first rotating seat 2 simultaneously, forming a triangular support structure. Similarly, when it needs to be stored, by pushing the gravity block 7 upward, the rotating rod 9 drives the main support leg 3 to retract towards the circular plate 1. At this time, the knob 114 is rotated in the opposite direction. The limiting rack 112 is re-engaged into the limiting hole 115 to lock the tension rod 6. When installing the surveying instrument body 15, the locking pin 16 is retracted by pulling the pulling plate 18. After the surveying instrument body 15 is placed between the two locking plates 14, it is released. At this time, under the push of the spring 17, the locking pin 16 will be locked into the slot on the outside of the surveying instrument body 15 to complete the fixation. When it is necessary to adjust the measurement angle, the second cone wheel 21 is rotated by rotating the manual wheel 22. Through the meshing transmission of the first cone wheel 20, the rotating column 19 can drive the rotating plate 13 and the surveying instrument body 15 to rotate horizontally, so as to realize multi-angle measurement and adjustment.
