Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: A surveying device for water conservancy projects includes a surveying platform 1 and a support for supporting the surveying platform 1. The surveying platform 1 is used for surveying work, and the support is used to stably support the surveying platform 1. The support includes a carrier plate 2 and at least three legs 3 rotatably mounted on the carrier plate 2. The surveying platform 1 is mounted on the carrier plate 2, and the three legs 3 are used to support the carrier plate 2. It should be noted that the rotational hinge locking structure between the legs 3 and the carrier plate 2 is an existing structure and will not be described in detail in this embodiment. Each leg 3 has a receiving cavity 4 at its bottom, and a flipping fixing claw 5 is installed in the receiving cavity 4. A locking mechanism 6 for locking the flipping fixing claw 5 is also installed in the receiving cavity 4. When the legs 3 are unfolded, the angle and height of the flipping fixing claw 5 can be adjusted to adapt to different measurement environments.

[0025] In this embodiment, the bottom of the support leg 3 extends longitudinally side by side to form two support plates, and a receiving cavity 4 is formed between the two support plates. The flip-fixing claw 5 can be rotated and slidably installed in the receiving cavity 4. On the one hand, the two support plates are used to adjust the usage state of the flip-fixing claw 5 with the cooperation of the locking mechanism 6. On the other hand, they accommodate the flip-fixing claw 5 to prevent damage during flip-fixing.

[0026] In this embodiment, one end of the flip-fixing claw 5 is integrally formed with a spherical support portion, and the other end is integrally formed with a pointed nail portion. If the environment is a hard surface, the spherical support portion can be used for stable support; if the environment is a soft surface, the pointed nail portion can be inserted into the surface for stable support. The choice can be made flexibly according to different environments, making it more adaptable.

[0027] In this embodiment, the support leg 3 has a first mounting hole 7 and a second mounting hole 8 that penetrate the two support plates laterally, and the first mounting hole 7 and the second mounting hole 8 are coaxially arranged. The locking mechanism 6 is placed in the receiving cavity and installed in the first mounting hole 7 and the second mounting hole 8.

[0028] In this embodiment, the locking mechanism 6 includes a locking bolt 61, a locking abutment kit 62 screwed onto the locking bolt 61, and an adjusting handle 63. The locking bolt 61 is rotatably mounted in the first mounting hole 7 and the second mounting hole 8. The adjusting handle 63 is located on the outer side of either support plate and is coaxially fixed to the locking bolt 61. A through-cavity 9 is provided in the middle of the flip-fixing claw 5, and the through-cavity 9 is arranged along the length direction of the flip-fixing claw 5. When the flip-fixing claw 5 is located in the receiving cavity 4, the locking bolt 61 passes through the through-cavity 9. The locking abutment kit 62 can be adjusted by the locking bolt 61 to abut against or move away from the side wall of the through-cavity 9. When the locking abutment kit 62 abuts against the side wall of the through-cavity 9, the flip-fixing claw 5 is fixed and limited to ensure that the flip-fixing claw 5 does not move relative to the support leg 3.

[0029] In this embodiment, the locking bolt component 61 includes a first stud 611 and a second stud 612, with the first stud 611 and the second stud 612 arranged in opposite helical directions. The locking abutment assembly 62 includes a first locking abutment sleeve 621 and a second locking abutment sleeve 622, with the first locking abutment sleeve 621 spirally sleeved on the first stud 611 and the second locking abutment sleeve 622 spirally sleeved on the second stud 612. The first stud 611 and the second stud 612 are coaxially inserted together. The first locking abutment sleeve 621 and the second locking abutment sleeve 622 are located on both sides of the flip-fixing claw 5, respectively. When the adjusting handle 63 is rotated, the first locking abutment sleeve 621 and the second locking abutment sleeve 622 move towards or away from each other, thereby clamping or releasing the flip-fixing claw 5.

[0030] It should be added that both the first locking abutment sleeve 621 and the second locking abutment sleeve 622 are fitted with rubber rings, which are truncated cone-shaped. The flipping fixing claw 5 has an inclined surface on its side wall at the through-cavity 9 that is adapted to the rubber ring. More preferably, several friction protrusions are provided on the inclined surface. When the rubber ring abuts against the inclined surface, the friction between the rubber ring and the inclined surface is increased, preventing relative movement between the flipping fixing claw 5 and the support leg 3 and ensuring its stability.

[0031] In this embodiment, both the first mounting hole 7 and the second mounting hole 8 are laterally recessed with limiting grooves communicating with their corresponding mounting holes. Both the first locking abutment sleeve 621 and the second locking abutment sleeve 622 are integrally formed with limiting protrusions that match their corresponding limiting grooves. Due to the cooperation between the limiting protrusions and the limiting grooves, when the adjusting handle 63 is rotated, the first screw drives the first locking abutment sleeve 621 to move axially within the first mounting hole 7, and the second screw drives the second locking abutment sleeve 622 to move axially within the second mounting hole 8. When the rubber ring abuts against the side wall of the penetrating slide cavity 9, the limiting protrusion remains within the corresponding limiting groove. Under the action of the first locking abutment sleeve 621 and the second locking abutment sleeve 622, the flipping fixing claw 5 is fixed.

[0032] In this embodiment, the first stud 611 has an integrally formed insertion portion at one end, and the second stud 612 has an integrally formed insertion sleeve at one end that is adapted to the insertion portion. The first stud 611 and the second stud 612 are coaxially arranged.

[0033] In this embodiment, an end cap 10 is installed on the support plate located at the first mounting hole 7. A first bearing 11 is installed inside the end cap 10. One end of the first stud 611 is coaxially installed inside the first bearing 11. The end cap 10 and the first bearing 11 cooperate to axially limit the first stud 611.

[0034] In this embodiment, a stepped hole is provided on the outer end face of the second mounting hole 8. A second bearing 12 is interference-fitted into the small hole of the stepped hole, and a second stud 612 coaxially passes through the second bearing 12. A retaining ring 13 is inserted into the second stud 612. The retaining ring 13 is located in the second mounting hole 8 and abuts against the second bearing 12, thereby axially limiting the second stud 612. Under the action of the end cap 10 and the retaining ring 13, the first stud 611 and the second stud 612 do not disengage from the receiving cavity 4 during operation.

[0035] When using this device, the angle of the support leg 3 is adjusted according to different surveying scenarios, and then the working state of the flip-fixed claw 5 is adjusted to ensure the stability of the surveying device during surveying. First, rotate the adjustment handle 63 clockwise, which drives the locking bolt 61 to rotate, and the locking abutment kit 62 moves away from the flip-fixed claw 5. Then, rotate and adjust the position of the flip-fixed claw 5 according to the specific environment. After the adjustment is completed, rotate the adjustment handle 63 counterclockwise, which drives the locking bolt 61 to rotate, and the locking abutment kit 62 abuts against the side wall of the through-cavity 9 of the flip-fixed claw 5, thereby fixing the flip-fixed claw 5.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
