Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy survey equipment, and in particular relates to survey equipment for water conservancy and hydropower construction. Background Art

[0002] As an important field of national infrastructure construction, water conservancy and hydropower engineering has many requirements for the abilities of professional talents. The relevant majors are aimed at cultivating senior engineering and technical talents who have knowledge of water conservancy and hydropower engineering survey, planning, design, construction, scientific research and management, and can engage in various related work in water conservancy and hydropower departments. Professional students need to learn basic theoretical knowledge such as mathematics, mechanics and building structures, and receive basic training in engineering design, construction management and scientific research methods, so as to have basic abilities in all aspects of water conservancy and hydropower engineering.

[0003] In the early stages of water conservancy and hydropower project construction, accurate surveying is essential. From the perspective of the engineering environment, water conservancy and hydropower projects may involve a variety of complex landforms such as mountains, plains, canyons, and waters. For example, when conducting geological surveys in mountainous areas, the terrain is drastic and the geological conditions in different areas vary greatly. In canyon areas, due to the narrow terrain and large drop, conventional surveying equipment that can only operate at a fixed angle often finds it difficult to conduct comprehensive and accurate surveys and sampling of specific locations, resulting in incomplete data and an inability to provide sufficient basis for subsequent engineering design and construction. In aquatic environments, the water flow velocity, water depth changes, and the complexity of underwater terrain also place higher demands on the flexibility and adaptability of surveying equipment.

[0004] At present, in the field of water conservancy and hydropower construction survey, although there are many survey equipment, they all have certain limitations. The utility model patent with authorization announcement number CN218156979U and main classification number G01N1 / 08 discloses a survey equipment for water conservancy and hydropower construction, which has a drilling mechanism and a protective mechanism. However, most of the existing survey equipment of this type can only drive the sampler to operate in the vertical direction. When faced with complex terrain and diverse survey needs, it is impossible to drive the sampler to rotate at multiple angles. This makes it impossible to obtain comprehensive survey data in some special areas, such as mountainous areas with large terrain undulations and areas with special geological structures, which seriously affects the accuracy and comprehensiveness of the survey data, and thus has an adverse impact on the scientific nature of the planning, design and construction of water conservancy and hydropower projects. Therefore, it is urgent to develop a survey equipment for water conservancy and hydropower construction that can realize multi-angle operation of the sampler. Summary of the invention

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] During the survey process, it is necessary to accurately measure data such as terrain and water level. From the perspective of the engineering environment, water conservancy and hydropower projects may involve a variety of terrain features such as mountains, plains, canyons and waters. For example, when conducting geological surveys in mountainous areas, due to the undulating terrain, conventional survey equipment can only operate at fixed angles, which often makes it difficult to survey and sample specific locations.

A first through hole is provided on the connecting frame 151, and one end of the rotating shaft 16 that rotates out of the outside of the connecting block 13 is rotatably arranged inside the first through hole. The rotating shaft 16 is rotatably connected to the connecting frame 151 through the first through hole. The axial position of the rotating shaft 16 is carefully designed to ensure the stability and precise swing of the connecting frame 151, so that the connecting frame 151 can swing left and right on the connecting block 13 and the fan-shaped mounting plate 14.

[0028] See also Figure 1-9 A limit block 27 is fixedly arranged at one end of the rotating shaft 16 that rotates and passes through the outside of the connecting block 13. The bottom of the limit block 27 slides and abuts against the connecting frame 151. An annular limit block 271 is fixedly arranged at one end of the limit block 27 that faces the connecting frame 151. An annular limit groove 272 that matches the annular limit block 271 is provided on the connecting frame 151. The annular limit block 271 is rotatably installed in the annular limit groove 272. The movement of the annular limit block 271 is constrained by the annular limit groove 272. Figure 3 and Figure 4 As shown, it is ensured that the connecting frame 151 can be kept swinging on the connecting block 13 and the fan-shaped mounting plate 14 when in the extreme swing position, thereby enhancing the safety and reliability of the entire system.

[0029] An arc-shaped limit groove 24 is provided on the moving block 12, and the arc-shaped limit groove 24 is connected to the inside of the first driving groove 17. An arc-shaped limit block 241 is slidably provided inside the arc-shaped limit groove 24. One end of the arc-shaped limit block 241 is connected to the fan gear 18, and the other end of the arc-shaped limit block 241 is connected to the connecting frame 151. When the arc block 15 drives the connecting frame 151 to swing, the connecting frame 151 can slide smoothly on the moving block 12, the connecting block 13 and the fan-shaped mounting plate 14, thereby improving the movement smoothness of the overall equipment.

[0030] A first driving groove 17 is provided inside the moving block 12, and a left-right swinging mechanism is provided inside the first driving groove 17. The left-right swinging mechanism is connected to the connecting plate 132. The left-right swinging mechanism is used to drive the fan-shaped driving block 142 to swing left-right inside the fan-shaped groove 141 through the connecting plate 132, thereby driving the arc block 15 to swing in the arc groove 143, and further driving the connecting frame 151 to swing left-right.

[0031] The left and right swinging mechanism includes a sector gear 18 movably installed inside the first driving groove 17. The top of the sector gear 18 is connected to the bottom of the connecting plate 132. A first slide groove is opened inside the moving block 12. A first rack 181 is slidably provided inside the first slide groove. The first rack 181 is meshed with the sector gear 18, ensuring the precise movement and driving efficiency of the sector gear 18.

[0032] When the first rack 181 slides left and right inside the first sliding part, it can drive the sector gear 18 to swing left and right. The sector gear 18 can drive the connecting plate 132 to swing left and right accordingly, thereby making the sector driving block 142 perform precise swinging operation in the sector groove 141.

[0033] With this design, when the first rack 181 slides, the movement of the entire mechanism is accurate and coherent, ensuring the efficient operation of the entire device. A transmission mechanism is provided inside the moving block 12, and the transmission mechanism is connected to the first rack 181. The transmission mechanism is used to drive the first rack 181 to move left and right inside the first slide slot, so that the first rack 181 can drive the sector gear 18 to rotate. Go to Figure 8 and Fig. 9 The transmission mechanism includes a second rack 182 slidably arranged inside the first slide slot, a mounting block 19 is fixedly arranged at one end of the second rack 182 facing the first rack 181, the mounting block 19 is connected to the first rack 181, the second rack 182 is connected to the first rack 181 through the mounting block 19, and the second rack 182 drives the first rack 181 to slide left and right correspondingly inside the first slide slot through the mounting block 19. The mounting block 19 ensures stable and accurate motion transmission between the second rack 182 and the first rack 181, further improving the overall reliability of the device.

[0034] A second driving groove 20 is provided inside the moving block 12, and the second driving groove 20 is connected to the first sliding groove. A driving gear 21 is rotatably installed inside the second driving groove 20, and the driving gear 21 is meshed with the second rack 182. A driving mechanism is provided on the moving block 12, and the driving mechanism is connected to the driving gear 21, and the driving mechanism is used to drive the driving gear 21 to rotate.

A driving shaft 23 is rotatably mounted inside the second through hole. The driving shaft 23 is connected to the driving gear 21. The output end of the first driving motor 22 is connected to the driving shaft 23. When the first driving motor 22 is started, its rotational power is transmitted to the driving gear 21 through the driving shaft 23, causing it to rotate. The engagement between the driving gear 21 and the second rack 182 causes the second rack 182 to slide along the first slide slot, and drives the first rack 181 to move left and right through the mounting block 19. This continuous transmission process ensures the precise rotation of the sector gear 18, thereby driving the entire device to operate efficiently and smoothly.

[0036] See also Figure 1-9 A lifting plate 152 is slidably provided on the connecting frame 151, and a sampler 153 is provided on the lifting plate 152. A lifting mechanism is provided on the connecting frame 151, and the lifting mechanism is connected to the lifting plate 152. The lifting mechanism controls the vertical movement of the lifting plate 152 so that the sampler 153 can accurately reach different sampling depths.

[0037] The lifting mechanism includes a first threaded rod 25 rotatably mounted on a connecting frame 151, the first threaded rod 25 extends in the up and down directions, a second slide groove is provided on the connecting frame 151 at intervals on the left and right, a slider 26 is provided inside the second slide groove for sliding movement, the slider 26 is connected to a lifting plate 152, the first threaded rod 25 is threadedly connected to the lifting plate 152, a second drive motor is installed on the connecting frame 151, and the output end of the second drive motor is connected to the first threaded rod 25.

[0038] The second drive motor drives the first threaded rod 25 to rotate, thereby realizing the precise vertical movement of the lifting plate 152. This fine control of the lifting mechanism enables the sampler 153 to stably reach the specified depth for sampling, ensuring the accuracy and repeatability of the data. The sampler 153 is a prior art and will not be described in detail here.

[0039] See also Figure 1-9 Working principle: When in use, fix the support frame 10 at the location to be surveyed, and then operate the control device to activate the third drive motor. After the third drive motor is started, the left and right moving distance of the moving block 12 in the through groove can be accurately controlled by rotating the second threaded rod 28, so that the moving block 12 can drive the connecting block 13 and the fan-shaped mounting plate 14 to move to the specific location to be surveyed.

[0040] At the same time, the first driving motor 22 is started, the driving shaft 23 rotates accordingly, and the driving gear 21 starts to rotate. The driving gear 21 drives the second rack 182 to slide along the first slide groove, and then the first rack 181 is moved left and right through the mounting block 19, and the first rack 181 drives the sector gear 18 to swing accurately, and the sector gear 18 drives the sector driving block 142 to swing in the opposite direction inside the sector groove 141 through the connecting plate 132, and the connecting plate 132 can swing inside the connecting groove 131 through the rotating shaft 16.

[0041] The fan-shaped driving block 142 drives the arc block 15 to slide synchronously inside the arc groove 143, and the arc block 15 drives the upper part of the connecting frame 151 to swing synchronously. At the same time, the fan gear 18 drives the lower part of the connecting frame 151 to swing synchronously through the arc limit block 241. Since the swinging directions of the fan gear 18 and the fan-shaped driving block 142 are opposite, the swinging of the connecting frame 151 is more stable, ensuring the verticality of the sampler 153 during the sampling process.

[0042] When the connecting frame 151 swings to the desired position, the second drive motor drives the first threaded rod 25 to rotate, thereby realizing the precise vertical movement of the lifting plate 152. This fine control of the lifting mechanism enables the sampler 153 to stably reach the specified depth for sampling, ensuring the accuracy and repeatability of the data.

[0043] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is limited by the appended claims rather than the above description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
