Description

Technical Field

[0001] This utility model relates to the field of hydrogeological technology, and in particular to a hydrogeological exploration device for coal mines. Background Technology

[0002] The importance of hydrogeological exploration in coal mines is reflected in the following aspects: improving mining efficiency and economic benefits. Hydrogeological problems directly affect the efficiency and economic benefits of coal mining. For example, rising groundwater levels may cause mine flooding, reducing mining efficiency, increasing equipment damage and operating costs. Therefore, it is necessary to use equipment to conduct hydrogeological exploration.

[0003] For example, a coal mine hydrogeological exploration device, with publication number CN220304618U, drives a worm gear to rotate, which in turn drives a turbine and a limiting cylinder to rotate. This causes the limiting cylinder to move the cylinder up and down, allowing workers to adjust the water level sensor according to the water depth. Bolts are inserted into the positioning hole to connect the connecting block to the first joint. Bolts are inserted into the inner wall of the second joint to fix the water level sensor to the outside of the second joint. A water pump is used to extract water from inside the cylinder, and the water is guided to the inside of the water storage tank through a hose. The water source is then tested by a water quality testing device.

[0004] However, because the cylinder thread is installed inside the limiting cylinder, in actual use, when the drilling depth is deep, the corresponding cylinder descent height will also increase. Since the cylinder's lifting and lowering depends on the rotation of the limiting cylinder, a longer or taller cylinder is required to ensure that the cylinder can be lifted and lowered to a fixed depth as the limiting cylinder rotates. Therefore, existing technology requires the use of a taller cylinder when facing deeper water levels, which makes transportation and assembly inconvenient. Utility Model Content

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figure 1-4 As shown:

[0024] A coal mine hydrogeological exploration device includes a fixed base 1. Two supports 2 are symmetrically fixedly connected to the center of the upper surface of the fixed base 1. A winch 3 is detachably mounted on the opposite face of the two supports 2 via bolts. A known hinge rope is wound on the winch 3, with one end of the rope passing through the center of the upper surface of the fixed base 1 and extending downward from the fixed base 1. Several water quality boxes 5 are connected to the free end of the hinge rope on the winch 3. The number of water quality boxes 5 is at least two, and the water quality boxes 5 are detachably stacked from top to bottom. The water quality boxes 5 are used to achieve different depths as the device descends into the borehole. For hydrological sample collection, a sliding seat 15 is positioned between two supports 2, below the winch 3. The sliding seat 15 slides back and forth along the length of the winding spool on the winch 3 and is fitted onto the winch rope. In actual use, the winch 3 is rotated to release the rope wound on its surface, allowing several water sample collection boxes 5 to descend into the pre-drilled holes. The water sample collection boxes 5 can be adjusted according to the water level in the holes by controlling the release length of the rope. The winch 3 is easy to carry and transport, and the sliding seat 15 can move as the rope is rotated and released, ensuring... Figure 1 and Figure 3 As shown, the rope released from the winch 3 descends vertically and then extends out through the fixed seat 1, ensuring that the rope is released and wound layer by layer during release and rewinding.

[0025] Furthermore: the two supports 2 are integrally formed horizontally below the winch 3 with their opposite faces. The sliding seat 15 is sleeved on the integrally formed part of the two supports 2, and the two supports 2 are rotatably connected to the electric screw 14 threadedly connected to the sliding seat 15. One of the supports 2 has a motor 16 installed on its upper and lower sides. The two motors 16 at the upper and lower positions are used to drive the winch 3 and the electric screw 14 to rotate, respectively. By installing the motors 16, the winch 3 or the electric screw 14 can be driven to rotate, so that the sliding seat 15 threadedly connected to the electric screw 14 can move horizontally under the constraint of penetrating the support 2.

[0026] Furthermore: An internally threaded ring 11 is fixedly installed on the outer side of the top of the water quality box 5, and an externally threaded ring 10 for threaded connection with the internally threaded ring 11 is fixedly installed on the outer side of the bottom of the box, facilitating the stacking of adjacent water quality boxes 5. A switch valve 12 is installed at the bottom edge of one side of the wall of the water quality box 5, and the center lines of several switch valves 12 in the stacked state are located in the same vertical plane. The switch valves 12 can be remotely controlled to open and close, allowing hydrological samples to enter the water quality box 5 or to extract hydrological samples collected in the water quality box 5 for testing. A known water pump is installed on one side of the upper surface of the fixing base 1, and a pump is installed on the same side of the lower surface. There is a vertical electric actuator 4, and a horizontal electric actuator 8 is installed at the telescopic end of the vertical electric actuator 4. A connector 9 for connecting to the water pump inlet is installed at the telescopic end of the horizontal electric actuator 8. In actual use, referring to the comparative example proposed in the background art, a water quality detection device is installed on the upper surface of the fixed base 1. Therefore, by telescopically extending the vertical electric actuator 4, the connector 9 can reach the corresponding water quality box 5. Then, by telescopically extending the horizontal electric actuator 8, the connector 9 can be inserted into the switch valve 12. The water sample in the water quality box 5 can be extracted by the water pump and the opened switch valve 12 and sent to the water quality detection device for testing.

[0027] Furthermore: A stabilizing cover 6 coaxially arranged with the water quality box 5 is fixedly installed on the bottom surface of the fixing base 1, and several stabilizing rods 7 are installed inside the stabilizing cover 6. The stabilizing cover 6 is flared and slidably connected to the top edge of the side of the water quality box 5. A slot 13 for inserting the stabilizing rods 7 is opened on the outer side of the top of the water quality box 5. In order to prevent the switch valve 12 from shaking when the connector 9 moves, the water quality box 5 is raised into the stabilizing cover 6 by winding the rope through the winch 3, and the stabilizing rods 7 inside the stabilizing cover 6 are inserted into the slot 13 on the top edge of the upper water quality box 5, so as to prevent the stacked water quality boxes 5 from shaking or rotating.

[0028] Working principle: Based on the number of samples, several water quality boxes 5 are stacked using the threaded connection between the internal threaded ring 11 and the external threaded ring 10. One end of the winch is connected to the top edge of the upper water quality box 5, and the fixing base 1 is fixed in the pre-drilled hole position. The motor 16 drives the winch 3 to rotate, releasing the winch and allowing the stacked water quality boxes 5 to be placed into the hole. When the water quality box 5 descends to a certain depth, one of the switch valves 12 is opened to allow the hydrological sample at that depth to enter the water quality box 5. Then, the switch valve 12 is closed. After collecting hydrological samples at different depths in the water quality box 5, the winch 3 winds up the rope to lift the water quality box 5 into the stabilizing cover 6. The stabilizing rod 7 inside the stabilizing cover 6 is then inserted into the slot 13 on the top edge of the upper water quality box 5. The vertical electric push rod 4 is then extended and retracted to allow the connector 9 to reach the corresponding water quality box 5. The horizontal electric push rod 8 is then extended and retracted to allow the connector 9 to be inserted into the switch valve 12. The hydrological samples in the water quality box 5 can then be extracted by the water pump and the open switch valve 12 and sent to the water quality testing device for testing.

[0029] The wiring diagrams for the vertical electric actuator 4, horizontal electric actuator 8, switching valve 12, motor 16, water pump, and water quality analyzer in this utility model are common knowledge in the field. Their working principles are well-known technologies, and the appropriate models are selected based on actual use. Therefore, the control methods and wiring arrangements for the vertical electric actuator 4, horizontal electric actuator 8, switching valve 12, motor 16, water pump, and water quality analyzer will not be explained in detail. The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may use the above-disclosed technical content to make changes or modifications to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model, without departing from the scope of the utility model's technical solution, shall still fall within the protection scope of this utility model's technical solution.
