Description

Technical Field

[0001] The utility model relates to the technical field of surveying, in particular to a portable surveying device. Background Art

[0002] Hydrological and water resources survey refers to the use of technologies to survey, measure, and record hydrological characteristics such as flow, water quality, water depth, water level, and seasonal changes of surface water, groundwater, rivers, and other water bodies to determine the characteristics of water resources and their changes.

[0003] Sampling plays a vital role in hydrological and water resource surveys. Sampling is the basis for obtaining hydrological and water resource data. Through sampling, key information such as water quality and water quantity can be obtained.

[0004] At present, when surveying water bodies such as rivers, it is necessary to sample the water bodies. The existing sampling tools can be roughly divided into two types according to the sampling method. One is sampling by standing on the shore, and the other is sampling by taking a water vehicle. The two sampling methods have their own advantages and disadvantages. Among them, the sampling and surveying device of the shore sampling is small and convenient to carry, but the disadvantage is that the water samples on the shore are difficult to reflect the water quality in the middle of the water body. Although sampling by taking a water vehicle can sample the middle area of ​​the water body, the disadvantage is that the whole is inconvenient to carry and the operation process is cumbersome. For this reason, a portable surveying device is proposed that can sample the middle area of ​​the water body on the shore. Utility Model Content

[0036] Step 1: Place the box 1, with one side of the running wheel 9 at a higher position on the shore and the other side at a lower position, and then adjust the two adjusting screws 12 until the box 1 is in a relatively stable state after placement;

[0037] Step 2: Extend the multi-section telescopic rod 5 to move the suspension assembly, and at the same time rotate the handwheel 7, which drives the worm 19 to rotate, and the worm 19 drives the worm gear 21 to rotate, and the worm gear 21 drives the reel 24 to rotate through the rotating shaft 22, thereby releasing the combined wires until the suspension assembly moves to the set area and the buoyancy chamber 3 falls to the water surface;

[0038] Step 3: Wind the combined wire around the counting wheel of the fishing line counter 6 for one circle, then reverse the handwheel 7, which drives the reel 24 to reverse through various components to reel in the combined wire until it is in a taut state and the counterweight housing 10 abuts against the bottom of the gate rod 4;

[0039] Step 4: Continue with the step 2 to release the combined wire operation. The weight housing 10 and the weight sampling bottle 11 enter the water under the action of gravity. The fishing line counter 6 determines whether the weight sampling bottle 11 reaches a specific depth range.

[0040] Step 5. After reaching the setting, the motor 15 drives the one-way screw 16 to rotate, the one-way screw 16 drives the square rod 17 to move, and the square rod 17 drives the closing valve plate 18 to rise until the opening is exposed, and water enters the counterweight sampling bottle 11. After the setting is actually reached, the closing assembly closes the opening, and then the components reset.

[0041] It should be noted that when it is actually put into use, batteries and single-chip microcomputers can be installed at appropriate locations, and the operation of the motor 15 can be controlled by the single-chip microcomputer.
