Description

Technical Field

[0002] Hydrological and water resources survey is an important work for river management and water resources development, utilization and protection. It covers many aspects such as engineering geological survey and groundwater resources survey, and provides basic data and scientific basis for optimizing water conservancy project planning, design, construction and operation. The technological development in this field is directly related to water resources management, environmental protection and the realization of sustainable development. In the process of hydrological and water resources survey, it is necessary to conduct preliminary testing of water quality and conduct subsequent water quality testing and analysis through sampling. However, traditional survey methods have many limitations, so it is necessary to design an intelligent survey device to provide more reliable technical support for water resources management and environmental protection.

[0003] The existing technology still has the following problems:

[0004] 1. Traditional surveying equipment is often fixed on the river bank or a fixed position, which greatly limits the survey area of ​​water resources, making the survey results not comprehensive and accurate. At the same time, the sampling components in traditional surveying equipment are often unable to collect water samples at different depths during actual use, resulting in poor real-time sample collection. The sampling components are easily mixed with more debris in the water during sampling, resulting in errors in the water sample detection and analysis results. In addition, in the process of sampling water resources at a fixed depth, water resources are easily contaminated by water resources at other depths, resulting in a decrease in the accuracy of water quality analysis.

[0005] 2. When traditional surveying equipment is operating on water, there are usually floating objects or fixed debris on the water, which will cause the equipment to be blocked when moving, thus affecting the preset water resource detection planning path, and even the surveying equipment will collide with obstacles when it comes into contact, causing damage to the parts of the surveying equipment, making it impossible to continue the survey work, thus delaying the survey work.

The fixed tube 315 is immersed in the water surface and contains a certain amount of water, so as to reduce the interference of the water contained in the inner cavity of the fixed tube 315 with the water sampled at different depths, that is, the rotating tube 314 and the fixed tube 315 are rotatably connected, and a connecting hole 316 is opened at the bottom end of the fixed tube 315, and a sampling bottle 317 is arranged in the inner cavity of the supporting ring 311, and a connecting tube 318 is arranged in the inner cavity of the sampling bottle 317, and a micro pump is arranged in the inner cavity of the sampling bottle 317, and the connecting tube 318 and the micro pump sleeve There are four sampling bottles 317, which are evenly distributed on the upper surface of the support ring 311. The bottom surface of one end of the rotating tube 314 away from the fixed tube 315 is flush with the upper surface of the connecting tube 318. The support ring 311 is fixedly connected to the upper surface of the survey body 1, and the fixed tube 315 is fixedly connected to the inner cavity of the survey body 1. The fixed tube 315 is made of hard material. When taking water, the belt 313 is driven to rotate by the operation of the second motor 312, and the rotation of the belt 313 drives the rotating tube 314 to rotate.

[0041] See also Figure 1 and Figure 6As shown, the pay-off mechanism 32 includes a pay-off frame 321, a third motor 322 is provided on one side of the pay-off frame 321, the inner cavity of the pay-off frame 321 is rotatably connected to a winding rod, the output end of the third motor 322 is sleeved with the winding rod, the outer surface of the winding rod is evenly wound with a pull rope 323, a support block 324 is fixedly installed on the outer surface of the survey body 1, a second cylinder 325 is fixedly installed on the outer surface of the support block 324, a second piston rod 326 is slidably connected to the inner cavity of the second cylinder 325, there are two pay-off frames 321, one end of the second piston rod 326 is in close contact with a first lifting block 327, the inner cavity of the first lifting block 327 is an inclined surface, the inclined surface is in close contact with the second piston rod 326, and one of the pay-off frames 321 is fixedly connected to the first lifting block 327, a limit rod 328 is fixedly installed on the upper surface of the survey body 1, the pay-off frame 321 is slidably connected to the limit rod 328, and the third motor 322 is controlled by the operation of the third motor 322.

When the descending depth of the sampling mechanism 34 stabilizes, the second piston rod 326 is driven to move in the inner cavity of the second cylinder 325 through the work of the second cylinder 325 on the support block 324. The movement of the second piston rod 326 drives the first lifting block 327 to rise. The rise of the first lifting block 327 drives one of the pay-off racks 321 to slide on the limit rod 328. At this time, the pull rope 323 on the pay-off rack 321 rises, which has a stretching effect on the sampling mechanism 34, that is, the valve of the sampling mechanism 34 is opened to collect water.

[0042] See also Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the sampling mechanism 34 includes a water collection cylinder 341, the inner cavity of the water collection cylinder 341 is fixedly installed with a limiting sleeve 342, the inner cavity of the limiting sleeve 342 is rotatably connected with a first threaded rod 343 through a thread, the first threaded rod 343 and the water collection cylinder 341 are rotatably connected, the limiting sleeve 342 and the inner wall of the water collection cylinder 341 are tightly fitted, the inner cavity of the limiting sleeve 342 is slidably connected with a sliding disk 344, the first threaded rod 343 and the sliding disk 344 are in contact, the upper surface of the sliding disk 344 is fixedly connected with a first spring 345, the end of the first spring 345 away from the sliding disk 344 is fixedly connected with a blocking block 346, the inner cavity of the water collection cylinder 341 is slidably connected with a sampling ring 347, the upper surface of the sampling ring 347 is fixedly installed with a sampling tube 348, the outer A water inlet hole 349 is provided on the surface, a second spring 3410 is sleeved on the outer surface of the sampling tube 348, a water intake hole 3411 is provided on the outer surface of the sampling ring 347, the sampling tube 348 is aligned with the water intake hole 3411, the sampling tube 348 is slidably connected to the top of the water collection cylinder 341, the blocking block 346 is slidably connected to the top of the water collection cylinder 341, the top of the limiting sleeve 342 is fixedly connected to the inner wall of the top of the water collection cylinder 341, the second spring 3410 is located between the sampling ring 347 and the bottom wall of the top of the water collection cylinder 341, the water inlet hole 349 of the sampling ring 347 is covered by the inner wall of the water collection cylinder 341 under the elastic force of the second spring 3410, there are two pull ropes 323, the top of the sampling ring 347 is fixedly connected to the pull rope 323, and the other pull rope 323 passes through the sampling ring 347. The water cylinder 341 is fixedly connected to the sampling ring 347, and the pull rope 323 passing through the water cylinder 341 is slidably connected to the water cylinder 341. The pull rope 323 connected to the sampling ring 347 is wound around the outer surface of the winding rod of the pay-off rack 321 located on the side of the first lifting block 327. The bottom end of the water cylinder 341 adopts a counterweight material to facilitate the sampling mechanism 34 as a whole to sink during sampling. When sampling, the pull rope 323 is paid out to the designed depth. At this time, the pull rope 323 connected to the sampling ring 347 is driven by the movement of the first lifting block 327 to move, and the sampling ring 347 is pulled to move. The pull rope 323 connected to the sampling ring 347 is slightly longer than the pull rope 323 connected to the water cylinder 341, ensuring that the two pull ropes 323 are synchronously paid out and reeled in when the water cylinder 341 The whole descends to the set depth under the action of the counterweight material. When the sampling ring 347 slides upward in the inner cavity of the water sampling cylinder 341 under the pull of the pull rope 323, the movement of the sampling ring 347 squeezes the second spring 3410, causing the sampling tube 348 to slide in the inner cavity of the water sampling cylinder 341. At this time, the water inlet hole 349 on the sampling tube 348 is exposed, so that the water source of a fixed depth enters the sampling tube 348 from the inner cavity of the water inlet hole 349, and then flows through the water intake hole 3411 and finally enters the inner cavity of the water sampling cylinder 341. The water inlet hole 349 adopts a small hole shape to prevent debris in the water from entering and preventing the debris from affecting the water source. After waiting for a period of time, the second piston rod 326 is reset to stop the pull of the pull rope 323 on the sampling ring 347.At this time, under the elastic force of the second spring 3410, the sampling ring 347 returns to its original position, so that the inner wall of the water collection tube 341 blocks the water inlet hole 349, preventing water sources at other depths from entering the inner cavity of the water collection tube 341 and polluting the water source at a fixed depth. The elastic force of the second spring 3410 needs to be able to block the water inlet hole 349 in the inner cavity of the water collection tube 341. At the same time, when the pull rope 323 connected to the sampling ring 347 is pulled, the sampling mechanism 34 will not be driven to move as a whole, that is, the water collection tube 341 will not be driven to move upward, otherwise the sampling mechanism 34 will not be driven to move upward. The sample ring 347 is displaced in the inner cavity of the water collection cylinder 341. When the water collection cylinder 341 is filled with water, the third motor 322 drives the two pull ropes 323 to move upward at the same time to prevent the sample ring 347 from moving in the inner cavity of the water collection cylinder 341. When the water collection cylinder 341 is pulled into the inner cavity of the limiting cylinder 33, the bottom end of the limiting cylinder 33 can correct the position of the sampling mechanism 34 so that one end of the blocking block 346 is directly opposite to the lowering of the fixed tube 315. The fixed tube 315 is made of hard material to facilitate the fixed tube 315 to generate pressure on the blocking block 346 when the fixed tube 315 generates pressure on the blocking block 346. 5 will not bend. When the top of the water collection cylinder 341 contacts the bottom of the survey body 1, the fixed tube 315 squeezes the blocking block 346, and the first spring 345 is compressed to the inner cavity of the water collection cylinder 341, so that the connecting hole 316 is located at the bottom of the water collection cylinder 341. At this time, the micro pump on the sampling bottle 317 is used to pump water, and the water source at a fixed depth in the inner cavity of the water collection cylinder 341 is pumped into the sampling bottle 317 for centralized collection. By rotating the first threaded rod 343, the sliding plate 344 slides in the inner cavity of the limiting sleeve 342, which is convenient for adjusting the first spring 3 45 and the squeezing force on the blocking block 346 make it easy to balance the blocking block 346 at the top position of the water collection cylinder 341. The inner diameter of the middle and lower end of the fixed tube 315 is smaller than that of the middle and upper end, which reduces the influence of the water contained in the inner cavity at the bottom of the fixed tube 315 on the water at a fixed depth. The depth of the water collection cylinder 341 is controlled by controlling the length of the rope 323, and water at different depths is collected in different sampling bottles 317. At the same time, the position of the movable survey body 1 can collect water sources in different areas, which is convenient for subsequent detection and evaluation of the water source.

At this time, the rotation of the guide wheel 517 drives the overall moving direction of the survey body 1 to change. At the same time, when a collision occurs, the guide wheel 517 as a whole generates a certain impact force on the first connecting rod 513. At this time, the first connecting rod 513 drives the sliding rod 514 to slide on the first sliding groove 512 in the inner cavity of the fixing ring 511. The elastic force of the third spring 516 restores the first connecting rod 513 to its original position, so that the guide wheel 517 has a certain buffering effect, thereby reducing the impact of the collision at the corner of the survey body 1 on the survey body 1 and avoiding damage to the equipment.
