Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0032] Please refer toFigures 1-10 The utility model discloses an underground water level data acquisition device, including fixed plate 1, this fixed plate 1 has a circular through -hole, installs water level acquisition mechanism 2 in the circular through -hole, still movably connected with first branch 3 and second branch 4 on the fixed plate 1, first branch 3 and second branch 4 are all connected with fixed plate 1 through tension spring 5 cooperation,

[0033] The fixed plate 1 is further provided with a threaded stud, and the threaded stud is threadedly connected with a placement rod 7, and the first branch 3 and the second branch 4 are further fixed with a protruding column 6 above the end away from the tension spring 5.

[0034] By adopting the above technical scheme, when the device is installed into the well, first, the lower end of the placement rod 7 is fixed with the threaded rod, then the two hollow rods are inserted on the protruding column 6, and the two hollow rods are moved inward, so that the first branch 3 and the second branch 4 are moved inward, and then the device is gradually placed in the appropriate position in the well; then the hollow rods are extracted; after the hollow rods are extracted, under the stretching of the tension spring 5, the first branch 3 and the second branch 4 are unfolded outward, so as to abut against the inner side of the well wall, thereby realizing the fixation of the whole device; then the placement rod 7 is twisted and extracted, and the water level data in the well can be collected through the water level collection mechanism 2.

[0035] In the embodiment, the water level collection mechanism 2 includes an outer cylinder 22, a battery compartment is arranged in the inner portion of the outer cylinder 22, and a top cover 21 and a conical cover 23 are respectively arranged on the top and bottom of the outer cylinder 22.

[0036] Specifically, the conical cover 23 has a protruding cylinder 231 inside; a limiting disc 232 is fixed in the protruding cylinder 231; a guide rod 24 is slidably connected to the inner side of the limiting disc 232, and the guide rod 24 is in a T-shaped structure; a float 25 is fixed to the bottom of the guide rod 24; a sliding contact 233 is embedded on the outer side of the top of the guide rod 24; the sliding contact 233 is slidably connected to the inner side of a resistance sheet 234; the resistance sheet 234 is in a C-shaped structure and is fixedly attached to the inner wall of the protruding cylinder 231; the sliding contact 233 and the resistance sheet 234 form a potentiometer.

[0037] By adopting the above technical scheme, after the device is installed, the float 25 is ensured to float on the water surface, when the water level rises or falls, the float 25 will drive the guide rod 24 to float up and down; the sliding contact 233 will slide up and down along the resistance sheet 234; the resistance value of the potentiometer will change with the change of the position of the sliding contact, by measuring the voltage signal output by the potentiometer, the change of the resistance value can be known, and then the position of the float can be converted; by comparing the position information of the float floating on the water surface for the first time, the height of the position compared with the initial position can be calculated, and then the rise and fall of the water level can be known.

[0038] For example, assuming the total resistance of the potentiometer's resistive elements is R, and when the sliding contact is at a certain position of the resistive elements, the resistance from that position to one end is R1. Under a constant voltage U, according to Ohm's law, the output voltage... The position of the float can be calculated by detecting the value of U1.

[0039] In this embodiment, the battery compartment includes two symmetrically arranged connecting plates 29, with a battery 210 disposed between the two connecting plates 29, and a circuit board 211 disposed on the outer side of one of the connecting plates 29; the two connecting plates 29 are disposed inside the inner cylinder 26.

[0043] The working principle of this utility model is as follows: When installing the device into the well, firstly, the lower end of the placement rod 7 is fixed to the screw rod. Then, two hollow rods are inserted into the protruding column 6, and the two hollow rods are moved inward, so that the first arm 3 and the second arm 4 move inward. Then, the device is gradually placed in a suitable position in the well. Next, the hollow rods are pulled out. After the hollow rods are pulled out, under the tension of the tension spring 5, the first arm 3 and the second arm 4 unfold outward, thereby abutting against the inner side of the well wall, thus fixing the entire device. Then, the placement rod 7 can be twisted and pulled away. Subsequently, the water level data in the well can be collected by the water level acquisition mechanism 2.

[0044] After the device is installed, ensure that the float 25 floats on the water surface. When the water level rises or falls, the float 25 will cause the guide rod 24 to move up and down. The sliding contact 233 will slide up and down along the resistive piece 234. The resistance value of the potentiometer will change with the position of the sliding contact. By measuring the voltage signal output by the potentiometer, the change in resistance value can be known, and then the position of the float can be calculated. By comparing it with the position information of the float when it first floats on the water surface, the height of the position relative to the initial position can be calculated, and then the rise and fall of the water level can be known.
