Description

Technical Field

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

[0002] Hydrogeology is the main purpose of engineering geological mapping. It provides data for studying geotechnical engineering problems and adverse geological phenomena related to groundwater activity. It studies data such as the permeability of soil and rock, the depth of groundwater and corrosivity, in order to determine the impact on foundation laying depth and foundation pit excavation.

[0003] A search revealed Chinese Patent Publication No. CN218297317U, which discloses a hydrogeological exploration device for coal mines. This patent includes two ground bases, with a ring fixedly connected between them. The inner wall of the ring has a threaded groove, within which an insertion mechanism is installed. The insertion mechanism includes a cylinder containing a marking mechanism. The upper end of the cylinder's inner wall has a second threaded groove, and the outer wall has a third threaded groove. Four handles are fixedly connected to the upper end of the cylinder. The device works by rotating a connecting ring, causing it to engage within the cylinder, and observing the markings on the handles. The markings ensure that the distance the long rod needs to extend out of the cylinder corresponds to the safety distance. When the buoy, under the action of buoyancy, causes the long rod to rise and protrude from the cylinder, it indicates that the water level has exceeded the warning level. This is intuitive and easy to observe. However, current coal mine hydrogeological exploration devices can only reflect water level height data. In actual hydrogeological exploration operations, the water level height is in a state of flux, and data related to the water flow direction is also needed. Furthermore, the data needs to be recorded. Existing devices lack the means to solve the above problems. Therefore, a coal mine hydrogeological exploration device is needed to solve or partially solve the above problems. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0018] The present invention will be further described below with reference to the accompanying drawings: like Figure 1 — Figure 6As shown, a coal mine hydrogeological exploration device includes an installation pipe 101. Several annularly arranged fixing plates 102 are fixedly connected to the bottom of the installation pipe 101. The installation pipe 101 and the fixing plates 102 are integrally formed. A fixing plate 103 is bolted to the top of the installation pipe 101. An installation mechanism is provided on the fixing plate 103. A fixing mechanism is installed inside the installation pipe 101. The fixing mechanism includes a limiting ring 301 and an installation ring 302. The limiting ring 301 and the installation ring 302 are bolted to the middle position inside the installation pipe 101. A movable opening is provided on the installation ring 302. An exploration mechanism is movably mounted on the mounting ring 302 in the groove 303. The exploration mechanism includes a movable rod 401, and a float 402 is bolted to the bottom of the movable rod 401. The float 402 can move and float up and down under the action of groundwater flow. A movable disk 403 is slidably connected to the middle position of the movable rod 401. The movable disk 403 is movably mounted on the mounting ring 302. A marking component is provided on the movable rod 401. A recording mechanism is provided inside the mounting tube 101. The recording mechanism includes replaceable recording paper 503, which is used to record the height and position of the marking component.

[0019] In this embodiment, the trace retention component includes a connecting plate 405, with a plurality of annularly arranged graphite heads 406 inserted into the side of the connecting plate 405. The movable rod 401 can move with the movement of the float 402. The movable rod 401 drives the connecting plate 405 to move inside the recording paper 503. The graphite heads 406 on the side of the connecting plate 405 can leave traces inside the recording paper 503, thereby recording the direction of water flow and the range of water level height.

[0020] In this embodiment, the recording mechanism includes a limiting strip 501, which is bolted to the inner wall of the mounting pipe 101. A limiting ring 502 is bolted to the bottom of the limiting strip 501. A slot is provided on the side of the limiting strip 501. The limiting strip 501 can restrict the placement of the recording paper 503, so that both ends of the recording paper 503 abut against the slot of the limiting strip 501, ensuring that the water flow direction reflected on each recording paper 503 is consistent. The limiting ring 502 can lock the bottom of the recording paper 503.

[0021] In this embodiment, the movable disk 403 is movably disposed between the limiting ring 301 and the mounting ring 302. The diameter of the movable disk 403 is smaller than the outer diameter of the limiting ring 301 and larger than the inner diameter of the limiting ring 301. The bottom of the movable disk 403 is connected to a movable ring 404 by bolts. The movable ring 404 is movably disposed in the movable groove 303 of the mounting ring 302. Lubricant can be applied to the movable groove 303 to prevent the movable ring 404 from exerting excessive resistance on the movement of the movable disk 403. When the movable rod 401 moves under the action of the float 402, the movable disk 403 and the movable ring 404 can move within the movable groove 303 of the mounting ring 302.

[0022] In this embodiment, the installation mechanism includes a handle 201, which is bolted to a fixing plate 103. A protective cover 202 is rotatably connected to the handle 201, and an observation window 203 is attached to the protective cover 202. A spare paper tube 204 is bolted to the fixing plate 103. The protective cover 202 is designed to prevent the complex environment in the mine from affecting the components inside the installation pipe 101, and the observation window 203 allows workers to easily observe the operation inside the installation pipe 101.

[0023] In this embodiment, a reflector 407 is bolted to the top of the movable rod 401. The reflector 407 is a cone-shaped component with reflective stickers. The reflector 407 can quickly determine the groundwater level without opening the protective cover 202.

[0024] Working principle: When using this device, first drill a hole at the hydrogeological exploration location, ensuring the hole is vertically positioned. After drilling, insert the installation tube 101 into the hole and fix the fixing plate 102 to both sides of the hole with bolts. Then, take out the recording paper 503, roll it into a tube, and insert it into the installation tube 101, aligning both sides of the recording paper 503 with the slots on the side of the limiting strip 501. After insertion, the bottom of the recording paper 503 should be at the top of the limiting ring 502. Then, close the protective cover 202. During hydrogeological exploration, groundwater flows through the gaps in the fixing plate 102, and the float 402 moves under the influence of the groundwater flow. As the movable rod 401 moves under the action of the float 402, the movable disc 403 and the movable ring 404 can move within the movable groove 303 of the mounting ring 302. The movable rod 401 drives the connecting disc 405 to move inside the recording paper 503. The graphite head 406 on the side of the connecting disc 405 can leave a mark on the inside of the recording paper 503. The height of the mark on the recording paper 503 reflects the water level, and the position of the mark on the recording paper 503 represents the direction of water flow, thus recording the direction of water flow and the range of water level. The staff regularly replaces the recording paper 503. The marks on the recording paper 503 reflect the hydrological data in the coal mine and are easy to preserve.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
