Description

Technical Field

[0001] The utility model relates to the technical field of geological detection, in particular to a groundwater flow detection device for hydrogeology. Background Technique

[0002] Hydrogeology is a branch discipline of geology, referring to various changes and movement phenomena of groundwater in nature. It mainly studies the distribution and formation law of groundwater, the physical properties and chemical components of groundwater, the rational utilization of groundwater resources, the adverse effects of groundwater on engineering construction and mine exploitation and their prevention and control, etc.; during the process of detecting the flow of groundwater, a groundwater detection device is often used for its use.

[0003] Referring to the AML920 groundwater flow velocity and direction meter, the detection method is to suspend the probe by a wire rope and insert the probe into the groundwater from the wellhead drilled by the exploration drill. In order to ensure that the depth that the probe can penetrate is sufficient, an independent wire rope, probe, and winding equipment for storing the wire rope need to be additionally equipped, which affects the portability of the overall device. At the same time, when it is necessary to obtain water samples for water quality detection, a groundwater extraction device also needs to be additionally equipped. Content of the Utility Model

[0004] The purpose of the utility model is to provide a groundwater flow detection device for hydrogeology to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A groundwater flow detection device for hydrogeology includes a device main body. A winding structure is rotatably installed inside the device main body. A detection structure is fixedly connected to the middle of the winding structure. The winding structure includes a winding groove. A winding shaft is rotatably installed in the middle of the winding groove through a bearing. The upper end of the winding shaft is interconnected with one end of a water suction pipe through a sealed bearing. The middle of the water suction pipe is fixedly connected to the output end of a water pump. The detection structure includes a detection probe. A wire rope connection seat communicated with the water suction channel is fixedly installed at the upper end of the detection probe. One end of an inner pipe is fixedly connected to the upper end opening of the wire rope connection seat.

[0007] Furthermore, the device body includes a suitcase-style device housing. A cover is hinged to the rear edge of the upper surface of the suitcase-style device housing. A display screen is embedded and installed on the inner surface of the cover. A handle is hinged to the front surface of the suitcase-style device housing. A control keyboard is fixedly installed on the upper surface of the suitcase-style device housing. A touchpad is embedded and installed on the front edge of the upper surface of the suitcase-style device housing. A data interface group is embedded and installed on one edge of the upper surface of the suitcase-style device housing. Lock catches are hinged to both ends of the upper edge of the cover. A battery slot is provided on one side of the suitcase-style device housing, and a detachable power supply is snap-fitted in the battery slot.

[0008] Furthermore, the upper end of the winding shaft is fixedly connected to one end of the synchronous pulley belt group, the other end of the synchronous pulley belt group is fixedly connected to the output end of the motor, and a probe storage card slot is penetrated and opened on the side wall of the rear edge of one side of the winding groove.

[0009] Furthermore, the lower end of the winding shaft is fixedly connected to the inner ring of the conductive slip ring.

[0010] Furthermore, the detection structure includes a detection probe. A pumping channel is penetrated and opened in the up-and-down direction in the middle of the detection probe, and a filter port is fixedly installed at the opening of the lower end of the pumping channel.

[0011] Furthermore, a waterproof and insulating inner sleeve is fixedly sleeved on the outside of the inner tube, a waterproof and insulating outer sleeve is sleeved on the outside of the waterproof and insulating inner sleeve, eight electric wires are fixedly installed at equal angles in a ring in the gap between the waterproof and insulating inner sleeve and the waterproof and insulating outer sleeve, and the other end of the inner tube is communicated with the water delivery channel.

[0012] Furthermore, the winding groove is opened inside the suitcase-style device housing. One end of the inner tube, the waterproof and insulating inner sleeve, the electric wires and the waterproof and insulating outer sleeve is fixedly connected to the middle of the winding shaft. The water delivery channel is opened inside the upper half of the winding shaft and is communicated with one end of the water extraction pipe.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. While the detection structure penetrates into the ground through the exploration well to detect the flow of groundwater, a sample extraction channel is opened inside the detection structure. Driven by a water pump, part of the groundwater is extracted from the opening at the lower end of the pumping channel, and then the water flow is pumped into the water extraction pipe through the inner tube inside the wire part of the detection structure and discharged from the other end of the water extraction pipe out of the suitcase-style device housing. While detecting the flow state of groundwater, it has the effect of water sample extraction, which is convenient for subsequent water quality detection work.

[0015] 2. The motor rotates the synchronous pulley belt group, which in turn rotates the winding shaft to wind the wire rope structure of the detection structure into the winding groove. When winding, the detection probe is inserted into the probe storage card slot. Equipping the detection structure on the device main body eliminates the need to independently equip the wire rope and probe structure during out-of-office inspections, improving the portability of the overall device.

[0016] 3. The battery is designed as a detachable power source. When performing external inspections, only the appropriate number of detachable power sources need to be carried according to the usage time, without the need to carry a large-sized mobile outdoor power source additionally, further improving the portability of the overall device.
