[0002] In the field of hydrogeological exploration, accurate detection and collection of groundwater level data are of vital importance for water resources assessment, geological research, and engineering construction. Traditional groundwater level detection methods often have many limitations and shortcomings.

[0003] In the past, commonly used groundwater level detection tools, such as simple water level measuring rulers, had low accuracy and could not meet the demand for accurate groundwater level measurement. Moreover, such tools were inconvenient to operate in complex geological environments and were easily disturbed by external factors, resulting in inaccurate measurement results. In addition, some early electronic water level detection devices, although they improved the measurement accuracy to a certain extent, had the problems of single function and low data collection efficiency. They can often only perform a single water level measurement, cannot realize continuous and real-time data collection, and cannot effectively record the dynamic process of water level changes. Based on this, we designed a detection device that can be directly installed at the groundwater outlet to detect the groundwater level in real time and can realize automatic recovery of the detector.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0026] like Figure 1-Figure 6As shown, a groundwater level detection and collection device for hydrogeological exploration includes a fixed bracket 1, a connecting arm 2, a detection guide mechanism 5 and a collection mechanism 3. The fixed bracket 1 is a rectangular frame structure, and the upper part of the fixed bracket 1 is provided with a connecting arm 2 and a detection guide mechanism 5; the detection guide mechanism 5 includes a connecting groove 501, a rotating shaft 508, a reel 507, a driving motor 509, a first gear 510, a second gear 511 and a meter 514. The rotating shaft 508 is arranged inside the connecting groove 501, and the rotating shaft 508 is provided with a second gear 511, and the second gear 511 is meshed and connected with the first gear 510 of the driving motor 509; the other end of the second gear 511 is connected and arranged with the meter 514 in the connecting bracket 512; the reel 507 is provided on the rotating shaft 508, and the wire rope 4 of the reel 507 is connected with the collection mechanism 3.

[0027] It should be noted that in the field of groundwater level detection, water level and water sample collection and detection are often necessary. However, during the use of existing groundwater level detection and collection devices, the detector is basically lowered by manpower, which is relatively laborious to use, and the lowering distance of the rope cannot be accurately measured, resulting in deviations in the measurement results. Based on this, we designed a groundwater level detection and collection device that can automatically retract and release the sensor and can measure the lowering length to improve the convenience of use; the connecting groove 501 is divided into a first chamber and a second chamber by an isolation plate, and the reel 507 is arranged in the first chamber, and the wire rope on the reel 507 passes through the through hole 506 at the bottom and is connected to the collection mechanism 3; a connecting support 512 is arranged inside the second chamber, and a second rotating shaft and a third gear are arranged inside the connecting support 512, and a third gear 513 is arranged on the second rotating shaft, and one end of the second rotating shaft is connected to a meter 514, which is arranged to calculate the length of the wire rope retracted and released when rotating.

[0028] It should be further explained that a detection guide mechanism 5 is arranged on the upper part of the fixed bracket 1 for guiding and lowering the collecting mechanism 3, wherein a rotating shaft 508 is arranged inside the connecting groove 501, and a reel 507 and a second gear 511 are arranged on the upper part of the rotating shaft 508, respectively. The reel 507 is driven by the driving motor 509 to realize the rotation of the reel 507, and during the rotation process, the steel wire rope 4 is retracted and released to realize the retraction and release of the entire collecting mechanism 3.

[0029] It should be further explained that in order to detect the distance that the entire wire rope is lowered, we designed a connecting support 512, and a rotating shaft is arranged inside the connecting support 512, and a third gear 513 is arranged on the upper part of the rotating shaft. The third gear 513 is meshed and connected with the second gear 511 on the rotating shaft 508, so as to drive the rotating shaft to rotate during the rotation of the rotating shaft 508. The rotating shaft is connected to the meter 514, which can calculate the length of the wound-up wire rope 4 during the rotation process, thereby realizing control.

[0030] like Figure 1 , Figure 2 and Figure 6 As shown, the collection mechanism 3 includes a first connecting platform 301, a connecting support 302, a second connecting platform, an auxiliary rotating wheel 307 and a sensing rod 303. One end of the first connecting platform 301 is connected to the second connecting platform through the connecting support 302 to form a support structure. A plurality of telescopic rods 305 are arranged on the upper part of the connecting support 302, and a pressure spring 306 is arranged on the outer wall of the telescopic rod 305 to form an elastic structure; a base is arranged at one end of the telescopic rod 305, and an auxiliary rotating wheel 307 is arranged inside the fixing ear of the base; the sensing rod 303 is arranged at the bottom of the second connecting platform, and a sensor is arranged inside the sensing rod 303, and a water-permeable hole 304 is arranged on the outer wall of the sensing rod 303.

[0031] It should be noted that during the entire process of introducing the collection mechanism 3, when the sensing rod 303 contacts the water source, it will transmit a signal, at which time the driving motor stops working, and the length of the lowered wire rope 4 can be obtained through the meter, thereby calculating the distance.

[0032] It should be further explained that during the lowering process of the collecting mechanism 3, the wire rope 4 will swing, causing the collecting mechanism 3 to collide with the inner wall of the hole and cause damage. Based on this, we have designed multiple telescopic rods 305 on the connecting pillar 302, and pressure springs 306 are provided on the outer wall of the telescopic rod 305 to form an elastic structure, and auxiliary wheels 307 are designed on the telescopic rod 305. When it is connected with the inner wall of the hole, the auxiliary wheels 307 can assist the entire collecting mechanism 3 in moving and guiding to prevent damage caused by contact between the two.

[0033] It should be further explained that, in order to prevent the collection mechanism 3 from having a large collision with the cave wall when swinging, we designed a telescopic rod 305, and a pressure spring 306 is arranged on the outer wall of the telescopic rod 305 to play a buffering role.

[0034] like Figure 1-Figure 6As shown, an opening and closing plate 502 is provided on the upper part of the first chamber of the connecting groove 501, and a lifting handle 503 is provided on the opening and closing plate 502; a protective cover 505 is provided on the upper part of the second chamber of the connecting groove 501, and a plurality of rectangular openings are provided on the protective cover 505; a guide group 9 is also included, and the guide group 9 includes a second fixing ear 901 and a guide wheel 902 arranged at the edge of the through hole 506, and the second fixing ears 901 are symmetrically arranged on both sides of the through hole 506, and the second fixing ears 901 are each provided with a guide wheel 902; a first connecting rod 6 is provided at the bottom of the fixing bracket 1, and a second connecting rod 8 is provided in the connecting groove of the first connecting rod 6, and a plurality of limiting holes and limiting pins are provided on the outside of the first connecting rod 6.

[0035] It should be noted that in order to reduce the swinging and assist the wire rope 4 in passing the wire during the guiding process, a guide group 9 is designed at the edge of the through hole 506 to assist the wire rope 4 in passing the wire through the guide wheel 902.

[0036] It should be further explained that, for ease of use, a first connecting rod 6 and a second connecting rod 8 are provided at the bottom of the fixed bracket 1, and the second connecting rod 8 can be adjusted inside the first connecting rod 6, so that the operator can adjust and use it easily.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
