Description

Technical Field

[0001] This utility model belongs to the field of groundwater monitoring technology, specifically relating to a groundwater flow direction measuring device. Background Technology

[0002] Groundwater is an important component of water resources and a vital source of water for agricultural irrigation, mining, and urban areas. It is closely related to human life and socio-economic development. The flow velocity and direction of groundwater are key research indicators for studying the characteristics of groundwater flow.

[0003] Chinese patent application number 202122878346.X discloses a groundwater flow velocity and direction measuring device, including a filter cylinder, a marker unit, an image acquisition unit, and an analysis and processing unit. The filter cylinder includes a base plate and a cylinder, with the base plate covering one end of the cylinder. The cylinder sidewall has several filter holes. The marker unit includes a compass, a marker, and a string. The compass is located on the base plate, the marker is inside the cylinder, one end of the string is connected to the marker, and the other end is connected to the base plate. The marker has a reference position directly above the compass and a marked position after flowing with the water. The image acquisition unit includes an end cap, a lighting device, and a camera module. The end cap is located at the other end of the cylinder, and the lighting device and camera module are located inside the cylinder, with the camera module facing the compass. The analysis and processing unit is communicatively connected to the image acquisition unit. The camera module acquires image information of the marker relative to the compass and transmits it to the analysis and processing unit to determine the groundwater flow velocity and direction.

[0004] In the aforementioned patent, after the device is sent into the groundwater through a thin rope, it is impossible to position the device. During the detection process, the device has low stability and will swing, which will affect the detection of the groundwater flow direction. During the lowering of the device, collisions can easily stick mud to the filter cylinder and block the filter holes, affecting the water flow and the impact force on the marker, thus interfering with the detection.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figure 1-3 The present invention provides the following technical solution: a groundwater flow direction measuring device, including a cylinder 3, an isolation component 4 connected to the bottom of the cylinder 3, a filter cylinder 5 embedded inside the isolation component 4, a compass 8 provided at the bottom of the filter cylinder 5, a marker 9 connected to the top of the compass 8, an image acquisition unit 7 installed inside the cylinder 3, an analysis and processing unit wiring 1 connected to the top of the image acquisition unit 7, a positioning component 2 provided at the top of the cylinder 3, and pull rope connecting rings 6 installed on both sides of the positioning component 2.

[0022] Specifically, the isolation component 4 includes a second motor 41, an isolation cylinder 42, a screw 43, and a transmission block 44. The bottom of the cylinder 3 is connected to the isolation cylinder 42, the bottom of the cylinder 3 is equipped with the second motor 41, the bottom of the second motor 41 is connected to the screw 43, and the inner top of the filter cylinder 5 is connected to the transmission block 44.

[0023] By adopting the above technical solution, the isolation cylinder 42 protects the outside of the filter cylinder 5, preventing external mud and dirt from scratching and clogging the filter cylinder 5 during the lowering process and affecting the flow direction detection. The starting motor 41 drives the screw 43 to rotate. Under the meshing connection between the screw 43 and the transmission block 44, the transmission block 44 can drive the filter cylinder 5 to move out of the isolation cylinder 42. The water flow impact on the marker 9 will cause the marker 9 to shift, which can improve the detection effect of the device.

[0024] Specifically, the filter cylinder 5 has four limiting blocks 45 connected to its side, and the insulating cylinder 42 has four limiting grooves 46 on its inner side. The limiting blocks 45 and the limiting grooves 46 are all equidistant from each other in a square.

[0025] By adopting the above technical solution, the sliding limit between the limiting block 45 and the limiting groove 46 improves the stability of the filter cylinder 5 and also limits the filter cylinder 5 to prevent it from separating from the isolation cylinder 42.

[0026] In this embodiment, after connecting the rope to the pull rope connecting ring 6, the groundwater flow direction measuring device can be lowered to the groundwater detection location. The isolation cylinder 42 protects the outside of the filter cylinder 5 to prevent external mud and dirt from scratching and clogging the filter cylinder 5 during the lowering process, thus affecting the flow direction detection. The motor 41 is started to drive the screw 43 to rotate. Under the meshing connection between the screw 43 and the transmission block 44, the limiting block 45 slides between the limiting groove 46. The transmission block 44 can drive the filter cylinder 5 to move out of the isolation cylinder 42. The water flow impact on the marker 9 will cause the marker 9 to deflect, which can improve the detection effect of the device. The image acquisition unit 7 transmits the marker 9 to the display screen through the analysis and processing unit wiring 1. By comparing the position of the marker 9 with the compass pointer 8, the flow direction of the groundwater can be determined.

[0027] Example 2

[0028] The difference between this embodiment and embodiment 1 is that the positioning component 2 includes a stop block 21, a slider 22, a lead screw 23, a groove 24, a first spur gear 25, a first motor 26, a second spur gear 27, and a fixed seat 28. Two fixed seats 28 are provided on the top of the cylinder 3. The groove 24 is opened inside the fixed seat 28. The slider 22 is embedded in the groove 24. The side end of the slider 22 is connected to the stop block 21. The lead screw 23 is embedded inside the slider 22. The first spur gear 25 is sleeved on the surface of the lead screw 23. The first motor 26 is provided on the top of the fixed seat 28. The second spur gear 27 is connected to the side of the first motor 26.

[0029] Specifically, the sides of spur gear 1 25 and spur gear 27 mesh with each other, and the threads on the surfaces of the lead screws 23 inside the two grooves 24 are in opposite directions.

[0030] By adopting the above technical solution, the starting motor 26 drives the spur gear 27 to rotate. Under the meshing transmission between the spur gear 27 and the spur gear 25, the lead screw 23 can be limited to rotate. Under the meshing connection between the lead screw 23 and the slider 22, the slide groove 24 limits the slider 22. The two sliders 22 can respectively drive the abutment block 21 to move outward and support it on the underground rock wall. The device can be oriented and positioned to improve the accuracy of groundwater flow direction detection.

[0031] Specifically, the surface of the spur gear 25 is in contact with the side of the fixed seat 28, and the surface of the slider 22 is in close contact with the inner wall of the groove 24.

[0032] By adopting the above technical solution, the surface of spur gear 25 is in contact with the side of the fixed seat 28, which makes the meshing between spur gear 27 and spur gear 25 more secure, and the device is better fixed and limited.

[0033] In this embodiment, the starting motor 26 drives the spur gear 27 to rotate. Under the meshing transmission between the spur gear 27 and the spur gear 25, the lead screw 23 can be limited to rotate. Under the meshing connection between the lead screw 23 and the slider 22, the slide groove 24 limits the slider 22. The two sliders 22 can respectively drive the abutment 21 to move outward and support it on the underground rock wall.

Its working principle is that after connecting the rope to the pull rope connecting ring 6, the groundwater flow direction measuring device can be lowered to the groundwater detection point. The filter cylinder 5 can filter the water flow. The water flow impacts the marker 9, causing the marker 9 to deflect. The image acquisition unit 7 transmits the marker 9 to the display screen through the analysis and processing unit wiring 1. By comparing the position of the marker 9 with the pointer of the compass 8, the direction of groundwater flow can be determined.

[0037] The working principle and usage process of this utility model are as follows: When using this utility model, after connecting the rope to the pull rope connecting ring 6, the groundwater flow direction measuring device can be lowered to the groundwater detection location. The motor 26 is started to drive the spur gear 27 to rotate. Under the meshing transmission between the spur gear 27 and the spur gear 25, the lead screw 23 can be limited to rotate. Under the meshing connection between the lead screw 23 and the slider 22, the slide groove 24 limits the slider 22. The two sliders 22 can respectively drive the abutment 21 to move outward and support it against the underground rock wall, thus enabling directional positioning of the device and improving the accuracy of groundwater flow direction detection. The isolation cylinder 42... The outer side of the filter cylinder 5 is protected to prevent external mud and dirt from clogging the filter cylinder 5 during the lowering process and affecting the flow direction detection. The start motor 41 drives the screw 43 to rotate. Under the meshing connection between the screw 43 and the transmission block 44, the limit block 45 slides between the limit groove 46. The transmission block 44 can drive the filter cylinder 5 to move out of the isolation cylinder 42. The water flow impact on the marker 9 will cause the marker 9 to deflect, which can improve the detection effect of the device. The image acquisition unit 7 transmits the marker 9 to the display screen through the analysis and processing unit wiring 1. By comparing the position of the marker 9 with the compass pointer 8, the flow direction of the groundwater can be determined.
