Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and particularly to a water conservancy project surveying and mapping device. Background Art

[0002] Water conservancy projects are various projects built to control, allocate, and utilize water resources. By building facilities such as dams, sluices, and channels, they play many functions such as flood control, irrigation, water supply, power generation, and shipping. Water conservancy project surveying and mapping is a technology that provides geospatial information for all stages of water conservancy project construction. In the planning and design stage, the terrain and landform are accurately surveyed and mapped, data is obtained using surveying instruments, and topographic maps are drawn to provide a basis for site selection and plan formulation. In the construction stage, through positioning measurement, it is ensured that the engineering buildings are accurately constructed according to the designed positions, and deformation is monitored in real time to ensure project safety. In the operation and management stage, the settlement, displacement, etc. of water conservancy facilities are continuously monitored to timely discover potential hazards. Water conservancy project surveying and mapping runs through the entire life cycle of water conservancy projects from planning to operation and maintenance, and is a key link to ensure the scientific construction and safe operation of projects.

[0003] In water conservancy project surveying and mapping operations, it is often necessary to conduct cross-section surveying of river channels. There are various existing river channel cross-section surveying technologies, such as handheld RTK surveying, surveying boat surveying, unmanned boat surveying, and unmanned aerial vehicle (UAV) surveying. Handheld RTK surveying requires staff to hold the device and cross the river channel for surveying. Its surveying process is not only very troublesome but also dangerous. During the surveying process, staff are prone to getting stuck in the river beach. Surveying boat surveying has the problem of high equipment costs, and due to the relatively deep draft of the surveying boat, the surveying boat is not suitable for surveying in shallow water areas. Unmanned boat surveying is greatly affected by the river water flow. When the water flow velocity of the river is relatively fast, it is very difficult for the unmanned boat to cross the river along a straight line, resulting in people having difficulty obtaining the river cross-section information at the specified position, and the unmanned boat is also easily washed away by the water flow and lost. Although UAV surveying can effectively solve the above problems, the energy consumption of the UAV is relatively large during flight, and the electric energy is consumed quickly. Therefore, the UAV cannot conduct long-term surveying operations and is difficult to conduct continuous multiple cross-section surveys, and the influence of the wind force on the flight route during UAV surveying is relatively obvious.

[0004] Therefore, there is an urgent need to provide a water conservancy project surveying and mapping device to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a water conservancy project surveying and mapping device.

[0006] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a water conservancy engineering surveying and mapping equipment, including a first column mechanism and a surveying and mapping mechanism, the top of the first column mechanism is bolted with a guide mechanism, the outside of the first column mechanism is also nested and fixed with a winding frame mechanism, and the winding frame mechanism is rotatably connected with a rope winding mechanism;

[0007] One end of the rope winding mechanism is connected to a second column mechanism;

[0008] A driving mechanism is rotatably arranged on the rope winding mechanism, and a surveying and mapping mechanism is bolted and fixed to the bottom of the driving mechanism.

[0009] The present invention is further configured as follows: the first column mechanism includes a column 1, a bottom plate 1 is welded and fixed to the bottom end of the column 1, and a plurality of ground nails are passed through the bottom plate 1.

[0010] Through the above technical solution, the column one and the base plate one are both made of stainless steel, which has strong corrosion resistance and high strength. The ground nails can fix the base plate one and the column one to the ground, thereby improving the stability of the column one.

[0011] The present invention is further configured as follows: the guide mechanism includes a mounting portion fixed to the top end of a column, a pulley frame is welded to the mounting portion, one end of the pulley frame is rotatably connected to a guide pulley one, a limiting baffle is also fixed to the pulley frame, and the other end of the pulley frame is rotatably connected to a guide pulley two.

[0012] Through the above technical solution, guide pulley one and guide pulley two can guide the steel cable and reduce the wear of the steel cable. Limit baffles are provided on the outside of guide pulley one and guide pulley two, and the limit baffles can effectively prevent the steel cable from detaching from guide pulley one or guide pulley two.

[0013] The present invention is further configured as follows: the winding frame mechanism includes a mounting hoop nested and fixed on the outside of a column, a connecting plate is bolted and fixed on the mounting hoop, a roller frame is welded and fixed on the connecting plate, a pawl is rotatably connected to the inner side of the roller frame, a pin hole is provided at one end of the pawl, a tension spring is also fixed on the pawl, and a spring pin is movably connected to the outside of the roller frame.

[0014] Through the above technical solution, the other end of the tension spring is fixed to a protrusion on the roller frame. The tension spring can form a pulling force on the tail end of the pawl. Under the action of the lever, the ratchet part of the pawl will tend to rotate downward. When the staff pushes the spring pin outward, the staff can press down the tail end of the pawl so that the pin hole is aligned with the spring pin. At this time, the staff releases the spring pin, and the spring pin will be inserted into the pin hole to limit the pawl. At this time, the ratchet end of the pawl is lifted.

[0015] The present invention is further configured as follows: The cable winding mechanism includes a roller shaft rotatably arranged inside the roller frame. A winding roller is fixed on the roller shaft, a ratchet wheel is fixed on the winding roller, and a steel cable is wound around the outside of the winding roller.

[0016] Through the above technical solution, the staff can release or wind up the steel cable by rotating the winding roller. When the staff needs to position the winding roller, the locking of the spring pin to the pawl can be released. At this time, the pawl is pressed against the ratchet wheel under the action of the tension spring. At this time, the winding roller can no longer release the steel cable, thereby limiting the length of the steel cable. When the staff needs to release or wind up the steel cable again, the pawl is limited and locked by the spring pin. At this time, the pawl no longer contacts the ratchet wheel, and at this time, the winding roller can rotate freely.

[0017] The present invention is further configured as follows: The second column mechanism includes a second column connected to the steel cable. A guiding pulley group is fixed at the top end of the second column, a bottom plate two is welded and fixed at the bottom end of the second column, and a rope-passing ear is also fixed on the second column.

[0018] Through the above technical solution, the guiding pulley group has the same structure as the guiding mechanism. Several ground nails are also arranged on the bottom plate two. The rope-passing ear can pass through and fix the end of the steel cable. The first column mechanism, the cable winding mechanism and the second column mechanism can jointly form an adjustable-spacing suspension structure, so that the device can be applicable to rivers or ponds with different widths.

[0019] The present invention is further configured as follows: The driving mechanism includes a driving pulley in rolling connection with the steel cable. An installation frame is rotatably connected to the outside of the driving pulley. A reduction motor is fixed on the installation frame. A connecting frame is bolted and fixed to the outside of the installation frame. Auxiliary pulleys are rotatably connected to both ends of the connecting frame. An installation plate is welded and fixed to the bottom end of the installation frame.

[0020] Through the above technical solution, the driving pulley and the auxiliary pulley are respectively pressed on the top end and the bottom end of the steel cable. The auxiliary pulley can effectively prevent the steel cable from disengaging from the driving pulley, and can also increase the pressure and contact area of the steel cable on the driving pulley, thereby improving the friction force between the driving pulley and the steel cable. The reduction motor is a remote control bidirectional motor, and the output shaft of the reduction motor is fixed to the axis of the driving pulley. When the staff controls the reduction motor to rotate forward or backward, the driving pulley will rotate, thereby driving the driving mechanism to move along the steel cable.

[0021] The present invention is further configured as follows: The surveying and mapping mechanism includes a waterproof machine box bolted and fixed to the bottom end of the installation plate. A radar flowmeter is fixed at the bottom end of the waterproof machine box. An electric telescopic rod is also fixed at the bottom end of the waterproof machine box. A driving motor is fixed on the electric telescopic rod, and a multibeam sounding instrument is fixedly installed at the end of the electric telescopic rod.

[0022] With the above technical solutions, the radar flowmeter can detect the water flow velocity, flow rate and liquid level height. Components such as a storage battery, a detection circuit, a charging circuit, and a networking module are installed inside the waterproof machine box, and the waterproof machine box can effectively protect these components from getting wet. The reduction motor, the radar flowmeter, the drive motor and the multi-beam depth sounder are all electrically connected to the corresponding devices inside the waterproof machine box. The drive motor is also a remote-controlled bidirectional motor, and the staff can control the forward and reverse rotation of the drive motor through remote control, so as to drive the electric telescopic rod to extend or contract, enabling the multi-beam depth sounder to penetrate into the water for depth sounding, thereby assisting people in mapping the river beach and underwater terrain.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. Through the setting of the first column mechanism, the rope winding mechanism and the second column mechanism, the present invention forms a suspension structure with adjustable spacing, so that the device can be applied to rivers with different widths, effectively improving the applicability of the device;

[0025] 2. Through the setting of the drive mechanism and the mapping mechanism, the detection mechanism can move along the suspension cable, so as to map multiple cross-sections of the river. Its structure is simple, the equipment cost is low, and there is no need for personnel to enter the water during the mapping process, improving the detection convenience of the device.
