Technical Field

[0001] The utility model relates to the technical field of mine exploration, in particular to a mine exploration water level measuring device. Background Art

[0002] The purpose and scope of mine exploration work are divided into three categories: geological exploration, infrastructure exploration, and production exploration. In the process of geological exploration of mining projects, hydrogeological problems will have a great impact on the construction of the project. Only by doing a good job of on-site exploration can we provide effective data support for subsequent engineering construction. In the process of mine exploration, it is often necessary to measure the depth of groundwater. Measuring the changes in groundwater levels is of great significance to water resource management, groundwater development and utilization, and environmental protection.

[0003] After drilling a measuring hole connected to the groundwater through mechanical equipment, the water level is measured through the measuring hole. The existing measurement method is mostly to lower a wire rope and judge the water level by the dry and wet boundary of the wire rope. The accuracy is low during long-distance measurement, and the water level measurement data cannot be obtained intuitively; measurement and sampling are carried out separately, which is time-consuming and labor-intensive.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: a mine exploration water level measuring device, including a frame 1, a motor 2 is arranged on one side of the frame 1, the output shaft of the motor 2 is connected to a roller 3, a tape 4 is wound on the roller 3, one end of the tape 4 is fixed on the roller 3, and the other end of the tape 4 is connected to a water level detection head 5, the water level is detected by the water level detection head 5, the water level detection head 5 includes a float liquid level switch 6 and a sampling tube 7, the float liquid level switch 6 contacts the liquid surface, when the float floats up under the action of buoyancy, the float liquid level switch 6 controls the motor 2 to brake, and the water body is sampled through the sampling tube 7.

[0024] Among them, the output shaft of the motor 2 is fixedly connected to the connecting shaft of the roller 3 through a coupling, and the connecting shaft of the roller 3 is connected to the frame 1 through a bearing. When the motor 2 is working, it drives the roller 3 to rotate, and when the roller 3 rotates, the measuring tape 4 is lengthened or reeled in. By controlling the rotation direction and number of turns of the motor 2, the length of the measuring tape 4 can be lengthened or reeled in.

[0025] Among them, the float liquid level switch 6 includes a reed switch, a float and a magnet. The entire measuring device is moved to the upper part of the measuring hole, and the motor 2 works to drive the roller 3 to rotate. The roller 3 lengthens the tape 4, and the water level probe 5 at the end of the tape 4 falls through the measuring hole. When the float liquid level switch 6 of the water level probe 5 contacts the liquid surface, the float floats up under the action of buoyancy, and the motor 2 is braked through the float liquid level switch 6 to stop lowering the water level probe 5. At this time, the scale 11 of the tape 4 is observed, and the lowering length of the tape 4 is intuitively obtained through the scale 11, so as to obtain the water level depth, realize rapid measurement of the water level, and achieve long-distance high-precision measurement.

[0026] After the data recording and measurement are completed, the motor 2 drives the roller 3 to rotate, and the tape 4 is rolled up by the roller 3, so that the water level detection head 5 and the sampling tube 7 at the end of the tape 4 are moved out of the measuring hole.

[0027] Among them, the sampling tube 7 is located at the lower part of the float liquid level switch 6. Before the float liquid level switch 6 of the water level detection head 5 contacts the liquid surface, the sampling tube 7 first contacts the liquid surface and immerses in the water layer. The water flows into the sampling tube 7 through the multiple groups of slots 8 of the sampling tube 7.

[0029] The sampling tube 7 and the connecting seat 9 are fixed by threads, and the sampling tube 7 and the connecting seat 9 are detachable structures. The sampling tube 7 can be separated from the connecting seat 9 by manually rotating the sampling tube 7, which is convenient for installation and disassembly of the sampling tube 7.

When the sampling tube 7 is immersed in the water layer, the water flows into the sampling tube 7 through the multiple groups of grooves 8 of the sampling tube 7 and is collected by the sampling tube 7, thereby realizing the sampling of the water body. The water level measurement and water sampling are carried out simultaneously, thereby improving the exploration efficiency.

[0031] Among them, a scale 11 is set on the ruler tape 4, and the lowering length of the ruler tape 4 can be intuitively obtained through the scale 11 of the ruler tape 4. When the float liquid level switch 6 of the water level detection head 5 contacts the liquid surface and controls the motor 2 to brake, the water level depth can be intuitively obtained through the scale 11, thereby realizing rapid measurement of the water level and improving the measurement accuracy.

The arrangement of the rollers 12 facilitates the movement of the entire water level measuring device, and the entire water level measuring device can be moved to a designated measuring area, which is easy to use.

[0033] Among them, a chassis 13 is arranged on the outer surface of the frame 1, and a mobile power module is built in the chassis 13. The mobile power module provides power support for the entire water level measuring device, so that the entire water level measuring device does not need an external power supply.

[0034] Working principle: After drilling a measuring hole connected to the groundwater through mechanical equipment, the overall water level measuring device is moved to the designated measuring area through the roller 12, and the water level is measured through the measuring hole. The mobile power module provides power support for the overall water level measuring device, and the motor 2 drives the roller 3 to rotate. The roller 3 lengthens the tape 4, and the water level probe 5 and the sampling tube 7 at the end of the tape 4 fall through the measuring hole. When the float level switch 6 of the water level probe 5 contacts the liquid surface, the float floats up under the action of buoyancy, and the motor 2 is braked through the float level switch 6 to stop lowering the water level probe 5. At this time, observe the scale 11 of the tape 4. The scale 11 can intuitively obtain the lowering length of the tape 4, so as to obtain the water level depth and realize rapid measurement of the water level. The sampling tube 7 is located at the lower part of the float liquid level switch 6. Before the float liquid level switch 6 of the water level detection head 5 contacts the liquid surface, the sampling tube 7 contacts the liquid surface first and immerses into the water layer. The water flows into the sampling tube 7 through the multiple groups of slots 8 of the sampling tube 7 and is collected by the sampling tube 7 to realize the sampling of the water body and record the data. After the measurement is completed, the motor 2 drives the roller 3 to rotate, and the tape 4 is wound up by the roller 3, and the water level detection head 5 at the end of the tape 4 and the sampling tube 7 are removed from the measuring hole, thereby completing the water level measurement and water sampling at the same time.
