Description

Technical Field

[0001] This invention belongs to the technical field of water conservancy construction surveying instruments, specifically relating to a surveying instrument for water conservancy engineering construction design. Background Technology

[0002] Water conservancy projects, also known as water engineering, aim to control and regulate surface water and groundwater in nature to achieve the goals of mitigating harm and promoting benefits. Water, as an indispensable and precious resource for human production and life, often exists in a state that cannot fully meet human needs in its natural state. Only by constructing water conservancy projects can we effectively control water flow, prevent floods, and rationally regulate and distribute water volume, thereby meeting the various water resource needs of people's lives and production.

[0003] To achieve this goal, water conservancy projects require the construction of various hydraulic structures such as dams, dikes, spillways, sluices, intakes, canals, ferries, rafts, and fishways. During the design and construction phase of water conservancy projects, accurate data measurement of the construction site is crucial, and this process cannot be separated from the use of measuring instruments.

[0004] Currently, most measuring instruments require a tripod for operation. However, the current tripod height adjustment mainly relies on pre-set fixing holes. Adjustment is achieved by inserting mounting components into holes of different heights. Since the spacing between the holes is fixed, this method cannot achieve precise height adjustment. Therefore, overcoming these technical problems and shortcomings is a key issue that needs to be addressed. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the current tripod height adjustment technology, which mainly relies on pre-set fixed holes. The height is adjusted by inserting the mounting parts into holes of different heights. However, since the spacing between the holes is fixed, this adjustment method cannot achieve precise height adjustment. Therefore, this invention provides a measuring instrument for water conservancy engineering construction design.

[0006] To achieve the above-mentioned objectives, the technical solution of this invention is: a measuring instrument for water conservancy engineering construction design, comprising a base, characterized in that: three mounting frames are fixedly and inclinedly installed at uniform intervals along the circumferential direction on the base; a lead screw is rotatably installed inside each mounting frame; a driving mechanism capable of driving the corresponding lead screw is installed on each mounting frame; a threaded sliding block is threadedly connected to each lead screw; a limiting component capable of limiting the threaded sliding block is installed on each mounting frame; a sliding frame is detachably installed on each threaded sliding block; a driving rod is rotatably installed on each sliding frame; a mounting seat is provided above the base; the end of each driving rod away from the sliding frame is rotatably connected to the mounting seat; and the measuring instrument body is fixedly installed on the upper end of the mounting seat.

[0007] In the aforementioned measuring instrument for water conservancy engineering construction design, the drive mechanism includes a drive motor fixedly mounted on the mounting frame and a drive bevel gear fixedly connected to the output shaft of the drive motor. A driven bevel gear meshing with the drive bevel gear is fixedly mounted on the lead screw.

[0008] In the aforementioned measuring instrument for water conservancy engineering construction design, the limiting component includes limiting rods symmetrically fixedly connected to both sides of the mounting frame and limiting sleeves fixedly connected to the four corners of the lower end of the threaded sliding block, and the limiting sleeves are fitted and slidably mounted on the limiting rods.

[0009] In the aforementioned measuring instruments for water conservancy engineering construction design, each of the sliding frames is detachably fixed to the threaded sliding block by threaded bolts.

[0010] In the aforementioned measuring instruments for water conservancy engineering construction design, each of the mounting frames is fixedly connected to a base at its lower end, and a universal ball is rotatably mounted at the lower center of each base. The lower end of the universal ball is fixedly connected to a mounting plate, and the lower end of the mounting plate is fixedly connected to several cones at even intervals.

[0011] In the aforementioned measuring instrument for water conservancy engineering construction design, a rectangular plate is installed at the lower middle part of the base, which can move up and down via a lifting mechanism, and universal wheels are symmetrically fixedly installed at the lower end of the rectangular plate.

[0012] In the aforementioned measuring instrument for water conservancy engineering construction design, the lifting mechanism includes a threaded rod and a threaded cylinder. The upper end of the threaded rod is fixedly connected to the base, and the threaded cylinder is threadedly connected to the threaded rod. The lower end of the threaded cylinder is fixedly connected to the upper end of the rectangular plate.

[0013] In the aforementioned measuring instrument for water conservancy engineering construction design, a microcontroller is fixedly installed on the mounting frame, and the output terminal of the microcontroller is electrically connected to three drive motors.

[0014] Compared with the prior art, the measuring instrument for hydraulic engineering construction design of the present invention has at least the following beneficial effects: 1. The measuring instrument for hydraulic engineering construction design of the present invention, through the installation of three evenly spaced inclined mounting frames on the base, and the setting of a lead screw, limit component, threaded sliding block and drive mechanism in each mounting frame, can accurately adjust the height of the mounting base according to the requirements, effectively overcoming the drawback of traditional measuring instruments that cannot achieve accurate height adjustment due to the fixed hole spacing.

[0015] 2. The measuring instrument for water conservancy engineering construction design of the present invention, through the combination structure of the base, universal ball, mounting plate and cone head set at the lower end of each mounting frame, allows the mounting plate to rotate within a certain range, thereby adjusting according to the unevenness of the ground, thus ensuring that the instrument always remains in a horizontal state, effectively improving the applicability and measurement accuracy of the instrument under different terrains.

[0016] 3. The measuring instrument for water conservancy engineering construction design of the present invention has a rectangular plate and casters installed at the lower middle part of the base via a lifting mechanism. When the instrument needs to be moved, the threaded cylinder is rotated to move the threaded rod downward inside the cylinder, thereby lowering the rectangular plate and casters. At this time, the instrument can be easily pushed to the designated position, which greatly facilitates the movement of the instrument. After reaching the position, the threaded cylinder is rotated in the opposite direction to retract the casters, so that the mounting plate contacts the ground, thereby effectively ensuring the stability of the instrument.

[0019] The measuring instrument for water conservancy engineering construction design of the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0020] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] Example 1: This embodiment discloses a measuring instrument for hydraulic engineering construction design. Through three evenly spaced, inclined mounting frames 2 installed on a base 1, and each mounting frame 2 equipped with a lead screw 4, a limiting component, a threaded sliding block 3, and a drive mechanism 8, the height of the mounting base 6 can be precisely adjusted according to requirements. This effectively overcomes the drawback of traditional measuring instruments that cannot achieve precise height adjustment due to fixed hole spacing. (Refer to...) Figures 1-6 The device mainly includes a base 1, characterized in that: three mounting frames 2 are fixedly and inclinedly installed at uniform intervals along the circumference of the base 1; a lead screw 4 is rotatably installed inside each mounting frame 2; a drive mechanism 8 that can drive the corresponding lead screw 4 is installed on each mounting frame 2; a threaded sliding block 3 is threadedly connected to each lead screw 4; and a limiting component that can limit the threaded sliding block 3 is installed on each mounting frame 2; a sliding frame 301 is detachably installed on each threaded sliding block 3; a drive rod 5 is rotatably installed on each sliding frame 301; a mounting seat 6 is provided above the base 1; the end of each drive rod 5 away from the sliding frame 301 is rotatably connected to the mounting seat 6; and a measuring instrument body 7 is fixedly installed on the upper end of the mounting seat 6.

[0022] In this embodiment, refer to Figures 1-6 The drive mechanism 8 includes a drive motor 801 fixedly mounted on the mounting frame 2 and a drive bevel gear 802 fixedly connected to the output shaft of the drive motor 801. A driven bevel gear 803 meshing with the drive bevel gear 802 is fixedly mounted on the lead screw 4. In actual use, the drive motor 801 is started, and the drive motor 801 drives the drive bevel gear 802 to rotate. The drive bevel gear 802 meshes with the driven bevel gear 803, causing the driven bevel gear 803 to rotate. The driven bevel gear 803 drives the lead screw 4 to rotate.

[0023] In this embodiment, refer to Figures 1-6The limiting component includes limiting rods 201 symmetrically fixedly connected to both sides of the mounting frame 2 and limiting sleeves 302 fixedly connected to the four corners of the lower end of the threaded sliding block 3. The limiting sleeves 302 are fitted and slidably mounted on the limiting rods 201. By setting the limiting rods 201 and the limiting sleeves 302, the threaded sliding block 3 can be limited, thereby effectively preventing the threaded sliding block 3 from rotating.

[0024] In this embodiment, refer to Figure 1 , Figure 2 and Figure 3 Each of the sliding frames 301 is detachably fixed to the threaded sliding block 3 by threaded bolts, which allows the drive rod 5, mounting base 6 and measuring instrument body 7 to be removed for easy carrying.

[0025] Example 2: Based on Embodiment 1, this embodiment discloses a measuring instrument for water conservancy engineering construction design. In this embodiment, referring to... Figure 1 , Figure 2 and Figure 3 Each mounting frame 2 has a base 9 fixedly connected to its lower end. A universal ball 10 is rotatably mounted in the middle of the lower end of each base 9. A mounting plate 11 is fixedly connected to the lower end of the universal ball 10. Several cones 12 are evenly spaced and fixedly connected to the lower end of the mounting plate 11. In actual use, the mounting plate 11 is rotated by the universal ball 10 until it is parallel to the ground. At this time, the cones 12 at the lower end of the mounting plate 11 are inserted into the ground. This allows for adjustment according to the unevenness of the ground, thereby ensuring that the instrument always remains horizontal and effectively improving the applicability and measurement accuracy of the instrument in different terrains.

[0026] Example 3: Based on Embodiment 1, this embodiment discloses a measuring instrument for water conservancy engineering construction design. In this embodiment, referring to... Figure 1 , Figure 2 and Figure 3A rectangular plate 15 is mounted on the lower middle part of the base 1, which can move up and down via a lifting mechanism. Universal wheels 16 are symmetrically fixed to the lower end of the rectangular plate 15. The lifting mechanism includes a threaded rod 13 and a threaded cylinder 14. The upper end of the threaded rod 13 is fixedly connected to the base 1, and the threaded cylinder 14 is threadedly connected to the threaded rod 13. The lower end of the threaded cylinder 14 is fixedly connected to the upper end of the rectangular plate 15. When the instrument needs to be moved, the threaded rod 13 moves downward within the threaded cylinder 14 by rotating the threaded cylinder 14, thereby lowering the rectangular plate 15 and the universal wheels 16. At this time, the instrument can be easily pushed to the designated position, greatly facilitating the movement of the instrument. After reaching the position, the threaded cylinder 14 is rotated in the opposite direction to retract the universal wheels 16, making the mounting plate 11 contact the ground, thus effectively ensuring the stability of the instrument.

[0027] Example 4: Based on Embodiment 1, this embodiment discloses a measuring instrument for water conservancy engineering construction design. A microcontroller (not shown in the figure; a microcontroller, also known as a microcontroller, is a small but complete microcomputer system that integrates a central processing unit, random access memory, read-only memory, multiple I / O ports and interrupt system, timer / counter and other functions (and may also include display driver circuit, pulse width modulation circuit, analog multiplexer, A / D converter and other circuits on a silicon chip) is fixedly installed on the mounting frame 2. Since it is an existing device, it will not be described in detail. The output terminal of the microcontroller is electrically connected to three drive motors 801. By controlling the start, stop and speed of the three drive motors 801 through the microcontroller, the moving speed and position of the three threaded sliding blocks 3 are precisely controlled, so that the mounting base 6 can be raised and lowered smoothly and evenly, further improving the convenience of instrument operation and the synchronization of raising and lowering.

[0028] The working principle of the measuring instrument for water conservancy engineering construction design of the present invention is as follows: When measurement is required, the instrument is moved to a suitable position by means of the universal wheel 16, and then the threaded cylinder 14 is rotated so that the rectangular plate 15 and the universal wheel 16 move upward until the mounting plate 11 can contact the ground. At this time, the mounting plate 11 is rotated to a suitable position by means of the universal ball 10, and the cone 12 at the lower end of the mounting plate 11 is inserted into the ground to ensure the stability of the measurement. Then the measurement is performed by means of the measuring instrument body 7. When different heights need to be measured, the microcontroller simultaneously controls the start of three drive motors 801. The drive motors 801 drive the active bevel gear 802 to rotate. The active bevel gear 802 meshes with the driven bevel gear 803, causing the driven bevel gear 803 to rotate. The driven bevel gear 803 drives the lead screw 4 to rotate. The lead screw 4 drives the threaded sliding block 3 to rotate. However, under the limiting position of the limit rod 201 and the limit sleeve 302, the threaded sliding block 3 moves up and down, which in turn drives the sliding frame 301 to move up and down. The sliding frame 301 drives the drive rod 5 to move up and down, so that the height of the mounting base 6 and the measuring instrument body 7 can be adjusted according to the requirements.
