Description

Technical Field

[0001] This utility model relates to the field of mining surveying technology, and more specifically, to a new type of high-efficiency surveying device for mining sites. Background Technology

[0002] The application of steel tape cable water level gauges in mines is mainly reflected in groundwater monitoring, engineering safety inspection and geological exploration. Through steel tape cable water level gauges, changes in groundwater level in boreholes and shafts in the mining area can be monitored in real time to ensure the stability of groundwater level during mining operations and prevent water inrush or leakage accidents. By regularly measuring the water level in shafts and combining it with historical data, the risk of water inrush can be predicted.

[0003] A search revealed a utility model patent with publication number CN219141949U, which discloses a steel ruler cable water level gauge, including a base, a roller, a steel ruler cable, and a probe. The roller is rotatably connected to the base, the steel ruler cable is wound around the roller, and the probe is connected to the end of the steel ruler cable. It includes a power supply, a button, and an audio-visual assembly located on the side of the roller. The power supply, probe, button, and audio-visual assembly are electrically connected. The probe is cylindrical in shape, with its lower end being conical. A through hole is provided at the lower part of the probe along its radial direction, and the detection end inside the probe extends into the through hole. A blind hole is provided on the side of the roller, and a slot is provided at the bottom of the blind hole. The power supply is inserted into the blind hole and locked in the slot, allowing it to be detachably connected to the blind hole. A gap is provided between the power supply and the sidewall of the blind hole. This patent reduces resistance during lowering, facilitates charging, and extends battery life. However, the aforementioned patent still has the following shortcomings: when using the steel tape cable level gauge, the operator needs to hold the steel tape cable with one hand and use the other hand to extend and retract the tape, which is inconvenient and affects the detection efficiency; in addition, when the steel tape cable is inserted into the mine, water stains and moisture will be picked up on the steel tape, and failure to clean it will affect the service life of the steel tape cable. Therefore, we propose a new type of high-efficiency measuring device for mining operations. Utility Model Content

In addition, the outer diameter of the sensing probe 4 is equal to the inner diameter of the placement cylinder 5, ensuring that the sensing probe 4 can be stably fitted into the inner cavity of the placement cylinder 5.

[0026] For details, please refer to Figures 1 to 5 The wiping mechanism 29 includes a support column 30 fixedly connected to the top surface of the support frame 6 and a support base 31 fixedly connected to the side surface of the support frame 6. An upper fixing block 11 is fixedly connected to the top surface of the support base 31. A second screw 12 is threadedly sleeved on the top end of the upper fixing block 11. A first side plate 13 is rotatably connected to the end of the second screw 12. Two mounting shafts 16 are fixedly connected to the inner side of the first side plate 13. A water-absorbing wiping roller 15 is movably sleeved on the outer side of each of the two mounting shafts 16. A threaded hole 17 is opened at the end of each of the two mounting shafts 16.

The bottom surface of the support rod 32 is flush with the top surface of the support frame 6 and the support base 31.

[0027] In this embodiment, the support rod 32 is used to support the first side plate 13 to ensure the stability of the first side plate 13, and at the same time, the first side plate 13 is limited so that the first side plate 13 can only move along the axial direction of the second screw 12.

[0028] For details, please refer to Figure 1 and Figure 3 The connecting mechanism 27 includes a connecting block 22 fixedly connected to the outer side of one end of the support frame 6 and an L-shaped mounting plate 21 fixedly connected to the side of the frame 3. The L-shaped mounting plate 21 is sleeved on the outer side of the connecting block 22, and a connecting bolt 23 is sleeved on the top of the L-shaped mounting plate 21. The bottom end of the connecting bolt 23 is threaded into the interior of the connecting block 22.

[0029] In this embodiment, the support frame 6 is installed on the side of the frame 3 by the cooperation of the L-shaped mounting plate 21, the connecting block 22 and the connecting bolt 23.

[0030] For details, please refer to Figure 3 and Figure 4 Two scraper blocks 20 are fixedly connected to the inner side of the first side plate 13, and the tops of the two scraper blocks 20 are in contact with the bottom surface of the water-absorbing wiping roller 15.

[0031] In this embodiment, there is a certain pressure between the scraper block 20 and the water-absorbing wiping roller 15 so that the water absorbed by the water-absorbing wiping roller 15 can be squeezed out by the scraper block 20.

[0032] For details, please refer to Figure 4 The outer diameter of one end of the round-headed screw 18 is equal to the inner diameter of the support hole 33.

[0033] In this embodiment, the stability of the round-headed screw 18 being inserted into the inner cavity of the support hole 33 is ensured, thereby ensuring the stability of the support for the mounting shaft 16 and the water-absorbing wiping roller 15.

[0034] For details, please refer to Figure 1 A handle 34 is provided on the top of the frame 3.

[0035] In this embodiment, the device is lifted and transported using handle 34.

[0036] Working principle: In use, first hold handle 34 and move the device to the inside of the observation tube, so that the tube wall is between push block 10 and lower fixing block 7. Then, turn knob 28 to rotate the first screw 8. Through the threaded engagement between the first screw 8 and the lower fixing block 7, push block 10 moves closer to the lower fixing block 7, so that the first rubber pad 9 on the inside of push block 10 and the second rubber pad 26 on the inside of lower fixing block 7 clamp the tube wall, thereby fixing the device above the observation tube. Then, the sensing probe 4 is then removed from the tube. Remove the steel ruler cable 2 from inside the placement cylinder 5 and pull it out from the outside of the winding roller 1 so that the sensing probe 4 can be inserted into the observation tube. Simultaneously, ensure that the steel ruler cable 2 contacts the outside of the second rubber pad 26. Then, rotate the winding roller 1 to release the steel ruler cable 2 from its outside. Guided by the guide wheel 25, the sensing probe 4 moves downward inside the observation tube to detect the water level. When the bottom of the sensing probe 4 detects water, read the value on the steel ruler cable 2 at the same height as the top of the observation tube. This value is the water level depth in the observation tube. After the inspection is completed, the operator rotates the second screw 12, which, through the threaded engagement between the second screw 12 and the upper fixing block 11, moves the first side plate 13 closer to the upper fixing block 11, inserting the steel ruler cable 2 between the two water-absorbing wiping rollers 15 on the side of the first side plate 13. At this time, the second screw 12 is reversed, and through the threaded engagement between the second screw 12 and the upper fixing block 11, the first side plate 13 is moved closer to the second side plate 19, so that the round-headed screw 18 at the end of the mounting shaft 16 is inserted into the inner cavity of the support hole 33. Rotating the take-up roller 1 drives the steel tape cable 2 to be wound up. At the same time, two water-absorbing wiping rollers 15 are used to wipe the outside of the steel tape cable 2. The water absorbed inside the water-absorbing wiping rollers 15 is squeezed out by the scraper block 20. After the steel tape cable 2 is wound up, the operator resets and rotates the second screw 12, so that the second screw 12 drives the first side plate 13 and the water-absorbing wiping rollers 15 away from the second side plate 19. The bottom end of the steel tape cable 2 is taken out between the two water-absorbing wiping rollers 15. After wiping the outside of the sensor probe 4 clean, it is inserted back into the placement cylinder 5.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
