Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy project surveying and mapping, and particularly relates to a surveying and mapping data acquisition system for river and lake water conservancy projects. Background Art

[0002] River and lake water conservancy projects refer to various projects such as flood control, waterlogging drainage, irrigation, hydropower generation, water diversion, beach treatment, soil and water conservation, and water resource protection, as well as their supporting and auxiliary projects. During the progress of river and lake water conservancy projects, a surveying and mapping data acquisition system is required. The surveying and mapping data acquisition system refers to a collection of a series of technologies, tools, and methods for obtaining geospatial data. These data can include surface features such as terrain, landform, buildings, and roads, as well as their attribute information, such as location, height, area, etc. Surveying and mapping data acquisition can be carried out in various ways, such as ground surveying, aerial photogrammetry, satellite remote sensing technology, etc. The surveying and mapping data acquisition system is fixed in a fixed area of the river and lake, and the acquisition end of the surveying and mapping data acquisition system is within a certain range from the water surface to have a better acquisition effect. However, the acquisition head of the existing surveying and mapping data acquisition system is fixedly arranged and cannot be self-adjusted according to the height of the water surface. In this way, when the water level is low, due to the long distance between the acquisition head and the water surface, the acquisition effect cannot be achieved. When the water level rises, it will also cause the surveying and mapping data acquisition system to be submerged below the water surface, resulting in damage to the surveying and mapping data acquisition system. To solve the above problems, a surveying and mapping data acquisition system for river and lake water conservancy projects is proposed in the present invention. Summary of the Invention

[0003] To achieve the above object, the present invention provides a surveying and mapping data acquisition system for river and lake water conservancy projects, including an acquisition device body and a fixing mechanism connected to the acquisition device body.

[0008] Optionally, the driving part includes a first screw column connected to the upper end surface of the first connecting rod.

[0013] The beneficial effects of the present invention are as follows:

[0014] The present invention improves the structure of the existing river and lake water conservancy project surveying and mapping data acquisition system. In the improved river and lake water conservancy project surveying and mapping data acquisition system, the acquisition device body is arranged on the fixing mechanism. The fixing mechanism includes a combined structure of a first fixing frame, a second fixing frame, a third fixing frame, a first moving column, a first floating ball, and a first support and reset component. The setting of this combined structure enables the acquisition device body to always self-adjust its height along with the height of the liquid surface. In this way, it can not only ensure that the acquisition head of the acquisition device body is always at the most suitable acquisition distance from the liquid surface, but also avoid the acquisition device body being submerged below the liquid surface when the water level rises, thereby playing a role in protecting the acquisition device body.

[0015] The moving mechanism provided in the present invention can make the first fixing frame move upward relative to the second fixing frame, which can further increase the height of the rise of the acquisition device body, thereby making the scope of use of this equipment wider. Specifically, when the first floating ball rises to the highest position, the liquid will enter the moving hole, thereby pushing the second floating ball upward. The movement of the second floating ball will drive the first fixing frame and the acquisition device body to move upward relative to the second fixing frame through the second moving column.

[0016] In the present invention, a plugging mechanism is provided. The setting of the plugging mechanism is used to plug the second through-hole, preventing the second through-hole from being opened when the first floating ball does not rise to the highest point, and preventing the first floating ball from being affected by the liquid entering the installation cavity during its upward movement. At the same time, the structure of the plugging mechanism is reasonably designed. When the first floating ball rises to the highest point, it can be automatically adjusted to open the second through-hole, so that when the first floating ball rises to the highest point, the liquid can enter the second through-hole, the installation cavity, the first through-hole, and the moving hole.

[0017] In the present invention, the structure of the plugging mechanism is reasonably designed. The specific process of opening the second through-hole is as follows: During the upward movement of the first floating ball, the pressing plate will contact the inner top wall of the third fixing frame and push the pressing plate to move downward with the second connecting rod. The downward movement of the second connecting rod will drive the second inner spiral tube to rotate clockwise through the second spiral column. The rotation of the second inner spiral tube will drive the first inner spiral tube to rotate clockwise. The rotation of the first inner spiral tube will drive the first connecting rod and the plug to move upward through the first spiral column, so that the plug disengages from the second through-hole, opening the second through-hole and allowing the liquid to enter the moving hole.

[0018] In the present invention, a filter plate is provided. The filter plate is used to filter and clean the liquid entering the moving hole, preventing larger debris from entering the moving hole and reducing the subsequent cleaning process.

[0019] In the present invention, a cleaning mechanism is provided to clean the sediment deposited on the filter plate, preventing the sediment from blocking the mesh holes of the filter plate and avoiding the situation where the liquid cannot enter the moving hole, enabling the equipment to operate smoothly. Moreover, the structure of the cleaning mechanism is reasonably designed and can move synchronously with the plugging mechanism 4, which can not only reduce the operation difficulty of the equipment but also improve the operation efficiency of the equipment.

The fixing mechanism 2 includes a combined structure of a first fixing frame 21, a second fixing frame 22, a third fixing frame 23, a first moving column 24, a first floating ball 25, and a first support and reset assembly 26. The setting of this combined structure enables the main body 1 of the acquisition device to always self-adjust its height along with the height of the liquid level. In this way, it can not only ensure that the acquisition head of the main body 1 of the acquisition device is always at the most suitable acquisition distance from the liquid level, but also avoid the main body 1 of the acquisition device being submerged below the liquid level when the water level rises, thereby playing a role in protecting the main body 1 of the acquisition device.

[0038] In one embodiment, the fixing mechanism 2 further includes a first support and reset assembly 26 on the lower end surface of the second fixing frame 22. The lower end of the first support and reset assembly 26 is fixedly connected to the bottom wall of the fixing groove 27.

The lower end of the second moving column 32 is fixedly connected to a second floating ball 33. The second floating ball 33 is movably arranged in the moving hole 31. The moving mechanism 3 provided in the present invention can make the first fixing frame 21 move upward relative to the second fixing frame 2, so as to further increase the height of the lifting of the acquisition device body 1, thereby making the range of use of the device wider. Specifically, when the first floating ball 25 rises to the highest position, the liquid will enter the moving hole 31, thereby pushing the second floating ball 33 upward. The movement of the second floating ball 33 will drive the first fixing frame 21 and the acquisition device body 1 to move upward relative to the second fixing frame 22 through the second moving column 32.

[0040] In one embodiment, the moving mechanism 3 further includes a second support and reset assembly 37. One end of the second support and reset assembly 37 is fixedly connected to the lower end surface of the first fixing frame 21.

The second support and reset rod 371 is movably inserted into the second support and reset cylinder 372. The second support and reset spring 373 is wound around the second support and reset rod 371. Two ends of the second support and reset spring 373 are respectively fixedly connected to the side wall of the second support and reset rod 371 and the outer side wall of the second support and reset cylinder 372.

[0041] In one embodiment, a plugging mechanism 4 is further included. The plugging mechanism 4 includes a plug 41 plugged in the second through hole 36. The upper end of the plug 41 is fixedly connected with a driving part. The driving part is arranged in the installation cavity 34. When the upper end of the driving part is pressed and moves downward, an upward pulling force will be provided to pull the plug 41 and the first connecting rod 42 upward, so that the plug 41 is separated from the second through hole 36.

[0042] In one embodiment, the driving part includes a first screw column 43 connected to the upper end face of the first connecting rod 42.

[0043] In the present invention, the structural design of the plugging mechanism 4 is reasonable. The specific process of opening the second through hole 36 is as follows: During the upward movement of the first floating ball 25, the pressing plate 411 will contact the inner top wall of the third fixing bracket 23 and push against the pressing plate 411 to drive the second connecting rod 410 to move downward. The downward movement of the second connecting rod 410 will drive the second internal screw tube 48 to rotate clockwise through the second screw column 49. The rotation of the second internal screw tube 48 will drive the first internal screw tube 44 to rotate clockwise. The rotation of the first internal screw tube 44 will drive the first connecting rod 42 and the plug 41 to move upward through the first screw column 43, so that the plug 41 is separated from the second through hole 36, opening the second through hole 36 and allowing the liquid to enter the moving hole 31.

[0048] The beneficial effects of the present invention are as follows:

[0049] The present invention improves the structure of the existing surveying and mapping data acquisition system for river and lake water conservancy projects. In the improved surveying and mapping data acquisition system for river and lake water conservancy projects, the acquisition device body 1 is arranged on the fixing mechanism 2. The fixing mechanism 2 includes a combined structure of a first fixing frame 21, a second fixing frame 22, a third fixing frame 23, a first moving column 24, a first floating ball 25, and a first support reset assembly 26. The setting of this combined structure enables the acquisition device body 1 to always self-adjust its height along with the height of the liquid surface. In this way, it can not only ensure that the acquisition head of the acquisition device body 1 is always at the most suitable acquisition distance from the liquid surface, but also avoid the acquisition device body 1 being submerged below the liquid surface when the water level rises, thus playing a role in protecting the acquisition device body 1.

[0050] The moving mechanism 3 provided in the present invention can make the first fixing frame 21 move upward relative to the second fixing frame 2, which can further increase the height that the acquisition device body 1 rises, so that the scope of use of this device is wider. Specifically, when the first floating ball 25 rises to the highest position, the liquid will enter the moving hole 31, thereby pushing the second floating ball 33 upward. The movement of the second floating ball 33 will drive the first fixing frame 21 and the acquisition device body 1 to move upward relative to the second fixing frame 22 through the second moving column 32.

[0051] The present invention is provided with a blocking mechanism 4. The setting of the blocking mechanism 4 is used to block the second through hole 36 to prevent the second through hole 36 from being opened when the first floating ball 25 does not rise to the highest point, and to prevent the first floating ball 25 from being affected by the liquid entering the installation cavity 34 during the upward movement; at the same time, the structural design of the blocking mechanism 4 is reasonable. When the first floating ball 25 rises to the highest point, it can be automatically adjusted to open the second through hole 36, so that when the first floating ball 25 rises to the highest point, the liquid can enter the second through hole 36, the installation cavity 34, the first through hole 35, and the moving hole 31.

[0052] The structural design of the blocking mechanism 4 in the present invention is reasonable. The specific process of opening the second through hole 36 is as follows: During the upward movement of the first floating ball 25, it will cause the pressing plate 411 to contact the inner top wall of the third fixing frame 23 and push the pressing plate 411 to drive the second connecting rod 410 to move downward. The downward movement of the second connecting rod 410 will drive the second inner spiral tube 48 to rotate clockwise through the second spiral column 49. The rotation of the second inner spiral tube 48 will drive the first inner spiral tube 44 to rotate clockwise. The rotation of the first inner spiral tube 44 will drive the first connecting rod 42 and the plug 41 to move upward through the first spiral column 43, so that the plug 41 is disengaged from the second through hole 36, opening the second through hole 36, and enabling the liquid to enter the moving hole 31.

[0053] In the present invention, a filter plate 6 is provided. The filter plate 6 is used to filter and clean the liquid entering the moving hole 31, to prevent larger debris from entering the moving hole 31, and to reduce the subsequent cleaning process.

[0054] In the present invention, a cleaning mechanism 5 is provided to clean the sediment deposited on the filter plate 6, to prevent the sediment from blocking the mesh holes of the filter plate 6, and to prevent the situation where the liquid cannot enter the moving hole 31, so that the equipment can operate smoothly. Moreover, the structural design of the cleaning mechanism 5 is reasonable and can move synchronously with the blocking mechanism 4, which can not only reduce the operation difficulty of the equipment but also improve the operation efficiency of the equipment.

[0055] Although the embodiments of the present invention have been described in detail above, it is obvious to those skilled in the art that various modifications and changes can be made to these embodiments. However, it should be understood that such modifications and changes are all within the scope and spirit of the present invention described in the claims. Moreover, the present invention described herein may have other embodiments and can be implemented or realized in various ways.
