Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy engineering measurement equipment, and particularly relates to an adjustable interval measuring instrument for water conservancy supervision. BACKGROUND

[0002] In water conservancy engineering supervision work, interval measurement is a crucial task, and accurate interval measurement plays a key role in ensuring that the construction of each part of the water conservancy engineering meets the design requirements. For example, in dam construction, the interval between different parts of the dam body needs to be accurately measured to ensure the stability of the dam structure; in the construction process of irrigation channels, the interval between the side walls of the channel also needs to be accurately measured to ensure the smoothness of the water flow, and many advanced interval measuring instruments use laser ranging technology. The measuring instrument emits a laser beam, the laser is reflected back when it encounters the measured object, and the instrument calculates the time difference between the emission and reception of the laser combined with the speed of light to obtain the distance between the measuring instrument and the measured object. For example, a common handheld laser range finder can quickly measure the interval of a long distance.

[0003] For the above related technologies, the inventors believe that the interval measuring instrument for water conservancy supervision in the prior art has many deficiencies. On the one hand, the height of most measuring instruments is fixed and cannot be flexibly adjusted, which makes it difficult to adapt to the interval measurement requirements of different height positions. For example, in the construction of some large water conservancy facilities, the interval at a higher position may need to be measured, and the measuring instrument with a fixed height cannot meet this requirement. On the other hand, the angle adjustment of the measuring instrument is not convenient enough during the measurement, which affects the measurement efficiency and accuracy. Moreover, the existing measuring instrument also has problems in terms of storage and carrying, which occupies a large space and is not convenient for supervision personnel to move between different sites. Therefore, in order to solve the above problems, the present application provides an adjustable interval measuring instrument for water conservancy supervision. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the problems proposed in the background art, the present application provides an adjustable interval measuring instrument for water conservancy supervision.

[0005] The adjustable water conservancy supervision distance measuring instrument provided by the application, including fixed rod, adjusting rod and storage assembly, the inside of the fixed rod is provided with a circular groove for the adjusting rod to enter, a first positioning hole is formed in the outer wall of the fixed rod near the top, a plurality of second positioning holes are equidistantly arranged on the surface of the adjusting rod, a bolt is threadedly connected in the first positioning hole and one of the second positioning holes, a supporting table is fixedly connected to the top of the adjusting rod, an adjusting box is fixedly connected to the top of the supporting table, a rotating rod is rotatably connected in the adjusting box, a first gear is fixedly connected to the outside of the rotating rod, a second gear is engaged with the outside of the first gear, the diameter of the first gear is smaller than that of the second gear, a rotating shaft is fixedly connected in the second gear, and the top end of the rotating shaft extends above the adjusting box and is detachably connected with a measuring instrument body through a support.

[0006] Preferably, the storage assembly comprises three equidistantly hinged supporting rods arranged on the outer wall of the fixed rod, a fixed groove is formed in the outer wall of the fixed rod below each supporting rod, and a storage rod is hingedly arranged in the fixed groove.

[0007] Preferably, a limiting block for limiting the rotation angle of the supporting rod is mounted on the outer wall of the fixed rod.

[0008] Preferably, the top end of the rotating rod extends above the adjusting box and is provided with a rotating handle, and the bottom end of the rotating shaft is rotatably connected with the inner wall of the bottom of the adjusting box.

[0009] Preferably, a conical block is mounted on the end of the supporting rod away from the fixed rod.

[0010] In summary, the application has the following beneficial technical effects:

[0011] 1. By forming a circular groove in the fixed rod for the adjusting rod to enter, and by cooperating the first positioning hole, the second positioning hole and the bolt, the extension length of the adjusting rod in the fixed rod can be flexibly adjusted according to the actual measurement requirements, thereby changing the overall height of the measuring instrument. This design makes the measuring instrument meet the distance measurement requirements of different height positions, greatly improving the application range of the measuring instrument.

[0012] 2. When the rotating rod is rotated, the principle of gear transmission can be used to accurately adjust the angle of the measuring instrument body. The smaller diameter of the first gear drives the larger diameter of the second gear to rotate, which can provide more precise angle changes, and it is convenient for measurement personnel to accurately adjust the measuring instrument according to the specific position and angle requirements of the measurement target, thereby significantly improving the accuracy and efficiency of measurement.

[0013] 3. When the measuring instrument is not in use, the support rod and the storage rod can be stored, greatly reducing the space occupied by the measuring instrument, and facilitating the measurement personnel to carry it to different water conservancy engineering sites. When in use, the conical block installed at the end of the support rod away from the fixed rod can be inserted into the ground, enhancing the stability of the measuring instrument, ensuring that the instrument will not easily shake during measurement, thereby improving the measurement accuracy.

DETAILED DESCRIPTION

[0019] The following will be described in detail in combination with the accompanying Figure 1 - Figure 4 The present application will be further described in detail.

[0020] Embodiment I:

[0021] A distance measuring instrument for water conservancy supervision, with reference to Figure 1 - Figure 4The utility model relates to a kind of height-adjustable measuring instrument, fixed rod 1, adjusting rod 2 and storage components are included, the inside of fixed rod 1 is opened with the round groove 3 for adjusting rod 2 to be active to enter, the outside wall of fixed rod 1 and the position close to top are opened with the first positioning hole 4, the surface of adjusting rod 2 is equidistant with multiple second positioning holes 5, the inside of first positioning hole 4 and one of second positioning holes 5 is commonly screw-threaded with bolt 6, the top of adjusting rod 2 is fixedly connected with support table 7, the top of support table 7 is fixedly connected with adjusting box 8, the inside of adjusting box 8 is rotatably connected with rotating rod 9, the outside of rotating rod 9 is fixedly connected with first gear 10, first gear 10 is engaged with second gear 11 outside, the diameter of first gear 10 is less than second gear 11, the inside of second gear 11 is fixedly connected with rotating shaft 12, rotating shaft 12 top end extends to the just above of adjusting box 8 and is detachably connected with measuring instrument body 13 by support, when needing to adjust the height of measuring instrument, loosen bolt 6, adjusting rod 2 can be moved up and down in round groove 3, reach appropriate height after, bolt 6 is passed through first positioning hole 4 and the second positioning hole 5 of corresponding position and is tightened, to fix the position of adjusting rod 2, realize the adjustment of the overall height of measuring instrument, to adapt to the spacing measurement demand of different height positions, since the diameter of first gear 10 is less than second gear 11, when rotating rotating rod 9, the rotation of first gear 10 will drive second gear 11 to rotate, according to the principle of gear transmission ratio, the cooperation of such size gear can realize more fine angle adjustment, the rotating shaft 12 fixedly connected in second gear 11 rotates along with the rotation of second gear 11, rotating shaft 12 top end extends to the just above of adjusting box 8, and is detachably connected with measuring instrument body 13 by support, to drive measuring instrument body 13 to realize the accurate adjustment of angle, to meet the spacing measurement requirement of different angle.

[0022] Referring to Figure 1 , Figure 2 and Figure 4The storage assembly comprises three equidistantly hinged support rods 14 arranged outside the fixed rod 1, a fixed groove 15 is arranged on the outer side wall of the fixed rod 1 directly below each support rod 14, and a storage rod 16 is hingedly arranged in the fixed groove 15. The outer side wall of the fixed rod 1 is hingedly arranged with three equidistant support rods 14, which can be unfolded outwardly to provide stable support for the measuring instrument. When the measuring instrument needs to be stored, the support rods 14 can be rotated towards the fixed rod 1 around the hinge points, and the fixed groove 15 arranged on the outer side wall of the fixed rod 1 directly below each support rod 14 and the storage rod 16 hingedly arranged in the fixed groove 15 can assist in storage and enhance stability. When storing, the support rods 14 are rotated to be close to the fixed rod 1, the storage rod 16 is also rotated around the hinge point with the fixed groove 15, and the end of the storage rod 16 away from the fixed groove 15 is hingedly arranged with the outer side wall of the support rod 14, so that the storage rod 16 can follow and adjust the position during the rotation of the support rod 14. Finally, the three support rods 14 and the storage rod 16 are stored close to the fixed rod 1, effectively reducing the space occupied by the measuring instrument in the storage state.

[0023] With reference to Figure 2 and Figure 4 , the outer side wall of the fixed rod 1 is provided with a limiting block 17 for limiting the rotation angle of the support rod 14. When the support rod 14 is unfolded outwardly, it will contact the limiting block 17 at a certain angle, thereby unable to continue rotating. This design ensures the consistency and stability of the angle of the support rod 14 in the unfolded state, avoids the instability of the measuring instrument caused by excessive rotation of the support rod 14, provides a reliable support foundation for the measurement process, and ensures the accuracy of the measurement.

[0024] With reference to Figure 3 , the top end of the rotating rod 9 extends above the adjusting box 8 and is provided with a rotating handle 18, and the bottom end of the rotating shaft 12 is rotationally connected with the inner wall of the bottom of the adjusting box 8. The operator can easily drive the rotating rod 9 to rotate in the adjusting box 8 by manually rotating the rotating handle 18. The rotation of the rotating rod 9 drives the first gear 10 fixedly connected thereto to rotate, thereby realizing the operation of the entire angle adjusting mechanism. The bottom end of the rotating shaft 12 is rotationally connected with the inner wall of the bottom of the adjusting box 8, thereby providing a stable support point for the rotating shaft 12, so that the rotating shaft 12 can remain stable when following the rotation of the second gear 11, thereby ensuring the stability and accuracy of the measuring instrument body 13 during the angle adjusting process.

[0025] With reference to Figure 2 , the end of the support rod 14 away from the fixed rod 1 is provided with a conical block 19. When the measuring instrument body 13 is placed on the ground for measurement, the conical block 19 can be inserted into the ground. Due to the shape characteristics of the conical block 19, it can provide better grip and stability after being inserted into the ground, preventing the measuring instrument from moving or shaking during the measurement process due to uneven ground or external force interference.

[0026] The implementation principle of the adjustable water conservancy supervision distance measuring instrument is that three supporting rods 14 are arranged on the outer side wall of the fixed rod 1 at equal intervals and can be unfolded outward to provide stable support for the measuring instrument. When the supporting rods 14 are unfolded outward, they will contact the limiting blocks 17 when they are rotated to a certain angle, so that they cannot continue to rotate. This design ensures the consistency and stability of the angle of the supporting rods 14 in the unfolded state, avoids the instability of the measuring instrument caused by excessive rotation of the supporting rods 14, provides a reliable support basis for the measurement process, and ensures the accuracy of the measurement. When the measuring instrument needs to be stored, the supporting rods 14 can be rotated around the hinge points towards the fixed rod 1. When stored, the supporting rods 14 are rotated close to the fixed rod 1, the storage rod 16 is also rotated around the hinge point with the fixed slot 15, and the end of the storage rod 16 away from the fixed slot 15 is hinged with the outer side wall of the supporting rod 14. During the rotation of the supporting rod 14, the storage rod 16 can follow and adjust the position. Finally, the three supporting rods 14 and the storage rod 16 are stored close to the fixed rod 1, effectively reducing the space occupied by the measuring instrument in the storage state. When the measuring instrument body 13 is placed on the ground for measurement, the conical block 19 can be inserted into the ground. Due to the shape characteristics of the conical block 19, it can provide better grip and stability after being inserted into the ground, preventing the measuring instrument from moving or shaking during the measurement process due to uneven ground or external interference. When the height of the measuring instrument needs to be adjusted, loosen the bolt 6, and the adjusting rod 2 can move up and down in the circular groove 3. After reaching the appropriate height, the bolt 6 is passed through the first positioning hole 4 and the corresponding second positioning hole 5 and tightened, thereby fixing the position of the adjusting rod 2 and achieving the adjustment of the overall height of the measuring instrument to adapt to the distance measurement requirements at different heights. The operator can easily rotate the rotating handle 18 to drive the rotating rod 9 to rotate in the adjusting box 8. When the rotating rod 9 is rotated, the rotation of the first gear 10 will drive the second gear 11 to rotate. Since the diameter of the first gear 10 is smaller than that of the second gear 11, according to the principle of gear transmission ratio, the cooperation of gears of different sizes can achieve more precise angle adjustment. The rotating shaft 12 fixedly connected inside the second gear 11 rotates with the second gear 11. The top end of the rotating shaft 12 extends above the adjusting box 8 and is detachably connected with the measuring instrument body 13 through a support, thereby driving the measuring instrument body 13 to achieve accurate angle adjustment to meet the distance measurement requirements at different angles.

However, those skilled in the art can understand that various modifications and improvements can be made to the above specific embodiments without departing from the concept of the present disclosure, and various technical features and structures proposed by the present disclosure can be combined without exceeding the protection scope of the present disclosure, and the protection scope of the present disclosure is determined by the appended claims.
