[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0035] Reference Figure 1 and Figure 2 In some embodiments of this utility model, the underground water inrush monitoring device for metal and non-metal mines includes:

[0036] Measuring container 10; Measuring container 10 is provided with a water inlet and a water outlet (not shown in the figure). The water inlet is provided with a water inlet connector 11, and the measuring container is provided with a scale 12 for reading the water volume of the measuring container. The water outlet is usually provided with a plug to facilitate the drainage of water after the measuring container is full of water.

[0037] Water-conducting hose 20; One end of the water-conducting hose 20 is connected to the water inlet connector 11, and the other end is connected to the drilling connector 30, used to deliver the gushing water from the borehole to the measuring container;

[0038] The drilling connector 30 includes a pipe body 31 and an expansion mechanism 32 disposed within the pipe body. The expansion mechanism 32 can extend into the borehole and connect to the inner wall of the borehole to fix the drilling connector in the borehole position; the water guide hose is connected to the pipe body.

[0039] When it is necessary to measure the water inflow of the borehole, the expansion mechanism is inserted into the borehole. The expansion device expands outward and connects tightly with the inner wall of the borehole, thus fixing the borehole joint to the borehole.

[0040] Then connect the water guide hose to the borehole connector and the other end to the water inlet connector to deliver the water gushing from the borehole into the measuring container.

[0041] The flow rate of water gushing from the borehole is measured by recording the water volume in the measuring container using the scale on the measuring container and calculating the increase in water volume in the measuring container per unit time.

[0042] The observation device has a simple structure and a stable connection with the borehole, preventing the borehole joint from falling off during the measurement process and ensuring measurement accuracy. Through the connection between the borehole joint and the borehole, it can be used to measure water inflow in boreholes in rock walls, tunnel roofs, and other locations. It does not use electrical equipment, making it convenient and safe to use in mine sites.

[0043] In some embodiments, refer to Figure 3 The tensioning mechanism 30 includes:

[0044] Fixed support; the fixed support is fixedly connected to the pipe body, including at least two fixed support rods 321, so as to... Figure 3 Taking the structure in the example as an example, the fixed bracket includes two fixed support rods 321;

[0045] Two movable rods 322 are provided, and each of the two movable rods 322 is hinged to one end of one of the two fixed support rods 321.

[0046] Support rod 323; two rods are provided, each of which is hinged at one end to one of the two movable rods 322 and at the other end to the movable part 324.

[0047] Adjusting rod 325; The adjusting rod 325 is arranged along the axial direction of the fixed bracket and is rotatably connected to the fixed bracket. The movable part 324 is connected to the adjusting rod 325 by transmission. When the adjusting rod rotates, it can drive the movable part to move along the axial direction of the adjusting rod.

[0048] Based on the structure of the aforementioned tensioning mechanism, when the adjusting rod rotates, it can drive the movable part to move towards the inside of the tube or away from the tube. Taking the movement away from the tube as an example, the movable part drives the support rod to move, and the support rod expands the movable part, so that the free end of the movable part forms a tensioning connection with the inner wall of the borehole, thus fixing the tube to the borehole opening.

[0049] In some embodiments, the free end of the movable rod 322 is configured as an anchoring section 3221, and the anchoring section 3221 and the movable rod 322 have an included angle that causes the anchoring section to bend outward. The anchoring section is provided at the end of the movable rod, and the anchoring section can be engaged in an irregular groove in the inner wall of the borehole, so that the tightening mechanism can form a more stable connection with the inner wall of the borehole.

[0050] In some embodiments, the fixed support rod 321, movable rod 322, and support rod 323 are configured as three or four. It is easy to see that the more movable rods there are, the more contact points between the tensioning mechanism and the inner wall of the borehole, thus better securing the pipe body in the borehole position. However, if there are too many movable rods, due to the potential irregularities in the inner wall of the borehole, interference may easily occur when the movable rods are spread apart, and the structure may become more complex. Therefore, it is generally preferred to use three or four.

[0051] In some embodiments, the fixed bracket includes a support frame 326 and a limiting frame 327 connected to the fixed support rod. The support frame 326 and the limiting frame 327 adopt a ring-shaped support structure. The adjusting rod 325 passes through the support frame and is rotatably connected to the support frame. For example, fixing nuts are respectively provided on both sides of the support frame on the adjusting rod. The fixing nuts cooperate with the support frame to restrict the movement of the adjusting rod in the axial direction, so that the adjusting rod can only rotate along its axis. A limiting ring 328 that cooperates with the adjusting rod is provided on the limiting frame. The adjusting rod 325 passes through the limiting ring 328 to provide circumferential support for the adjusting rod.

[0052] In some embodiments, refer to Figure 4 A collection hopper 40, shaped like a funnel, is installed at one end of the pipe body 31. The collection hopper is used to collect the water gushing from the borehole opening, allowing the water to flow well into the water guide hose and thus improving the accuracy of the measurement.

[0053] The collecting bucket 40 is made of elastic rubber material, which allows the collecting bucket to deform elastically and form a good sealing fit with the irregular rock wall at the borehole opening, further ensuring the accuracy of the measurement.

[0054] In some embodiments, such as Figure 4 The collecting hopper 40 includes a connecting sleeve 41, which is fitted onto the pipe body 31, making the collecting hopper and the pipe body a separate structure. The connecting sleeve is made of rubber material, which has a certain degree of elasticity, allowing it to tightly wrap around the pipe body and form a sealed connection.

[0055] In this way, when installing the borehole joint, the tightening mechanism can be inserted into the borehole first. Rotating the adjusting rod drives the movable part to move into the borehole. At this time, the movable part drives the support rod to move, and the support rod pushes the movable rod outward. The anchoring section of the movable rod forms a snap-fit ​​with the inner wall of the borehole. After fixing the pipe body, the collection bucket is adjusted towards the borehole opening so that the flared mouth of the collection bucket fits against the rock wall around the borehole opening. This structure and fixing method can reduce the impact of water gushing on the pipe body when fixing it, and facilitate the fixing and installation of the pipe body.

[0056] When the water guide hose 20 is connected to the pipe body 31, the end face of the water guide hose 20 abuts against the end face of the connecting sleeve 41. The abutting arrangement between the two can provide a certain supporting force for the collection bucket and prevent the collection bucket from shifting under the impact of the gushing water.

[0057] In some embodiments, the observation device further includes a timer for timing.

[0058] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0059] Furthermore, the use of terms such as "horizontal" or "vertical" in the description of this utility model does not imply that the component is required to be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0060] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0061] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
