[0002] Mine drainage ditches are ditch systems used in mining engineering to divert and drain floodwater or accumulated water within the mining area. They are usually set up at specific locations on the surface or underground. Their main function is to prevent water accumulation in the mining area caused by factors such as heavy rain and groundwater infiltration, avoid safety accidents such as water seepage and collapse, and ensure the safety of underground operations and the normal operation of equipment. The water level changes of mine drainage ditches directly reflect their flood discharge capacity. In order to understand the water level changes of mine drainage ditches in a timely manner, it is necessary to use a real-time water level monitoring device. Utility Model Content

[0068] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided by this invention. However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.

[0069] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0070] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0071] like Figures 1 to 8 As shown in the figure, this application proposes a real-time water level monitoring device for mine drainage ditches, including: a base assembly 110, which is used to be erected on the mine drainage ditch; a column 120, which is set on the base assembly 110 and has a receiving cavity in the middle; a lifting column 130, which is set in the receiving cavity of the column 120; an electrical control box 140 and a water level sensor 150, wherein the electrical control box 140 is connected to the end of the lifting column 130 away from the base assembly 110, and the water level sensor 150 is connected to the electrical control box 140 through a cable 2034.

[0072] The real-time water level monitoring device for mine drainage ditches provided in this application embodiment includes a base assembly 110, a column 120, a lifting column 130, an electrical control box 140, and a water level sensor 150. Based on this, during the use of the real-time water level monitoring device for mine drainage ditches, the base assembly 110 can be placed on the mine drainage ditches. The base assembly 110 can be erected on both sides of the mine drainage ditches, so that the lifting column 130, the column 120, the electrical control box 140, and the water level sensor 150 are directly above the mine drainage ditches. Then, by lowering the water level sensor 150 into the mine drainage ditches, the water level of the mine drainage ditches can be detected in real time. By adjusting the height of the electrical control box 140 through the lifting column 130, the height of the water level sensor 150 can be adjusted, making the real-time water level monitoring device for mine drainage ditches suitable for different application scenarios and for mine drainage ditches of different sizes.

[0073] It is understood that the base 111 of the real-time water level monitoring device for mine drainage ditches provided in this application embodiment is erected on the mine drainage ditches, allowing the water level sensor 150 to be arranged directly above the mine drainage ditches for more accurate detection. Furthermore, the device only occupies space above the mine drainage ditches, so when monitoring the water level in the mine drainage ditches is required, the real-time water level monitoring device can be installed without disassembling the ditches, and it will not affect the layout of equipment around the mine drainage ditches.

[0074] It is understood that the real-time water level monitoring device for mine drainage ditches provided in this application embodiment can support the lifting column 130 through the column 120. On the one hand, the lifting column 130 can be used to drive the electrical control box 140 to rise or fall more stably; on the other hand, it can reduce the probability of the lifting column 130 tipping over, making the device safer and more reliable to use.

[0075] like Figure 6 As shown, in one feasible embodiment, the base assembly 110 includes: a base 111, on which at least two grooves are formed; a slide block 112 and a slide rod 113, wherein there are two slide blocks 112, each slide block 112 is connected to a slide rod 113, the two slide blocks 112 are disposed on both sides of the base 111 through the slide rod 113 and the grooves, and the slide blocks 112 are used to be erected on the mine drainage ditch; and an abutment unit 114, which is connected to the side of the slide block 112 near the base 111 and is used to abut against the inner wall of the mine drainage ditch.

[0076] In this technical solution, considering that the width of mine drainage ditches varies depending on their specifications or usage scenarios, a base assembly 110 is further provided. The base assembly 110 may include a base 111, a slide 112, a sliding rod 113, and an abutment unit 114. The base 111 serves as the main carrier supporting the column 120, the lifting column 130, the electrical control box 140, and the water level sensor 150. The slide 112 is slidably connected to the base 111 via the sliding rod 113 and a sliding groove, allowing the position of the slide 112 relative to the base 111 to be adjustable. This adjusts the effective width of the base 111, ensuring that the slide 112 can be erected on the bank of the mine drainage ditch, facilitating the fixation of the real-time water level monitoring device in the mine drainage ditch. By setting the abutment unit 114, the abutment unit 114 is connected to the slide 112 and abuts against the inner wall of the mine drainage ditch, which can play the role of fixing the real-time water level monitoring device of the mine drainage ditch, thus ensuring the reliability of fixing the real-time water level monitoring device of the mine drainage ditch.

[0077] like Figure 6 As shown, in one feasible embodiment, the abutment unit 114 includes: a through groove 1141, which is formed on the slide 112; a fixing plate 1142, which is connected to the slide 112; a screw 1143, one end of which passes through the fixing plate 1142; a handwheel 1144, which is connected to the other end of the screw 1143; a sliding plate 1145, which is connected to the end of the screw 1143 that passes through the fixing plate 1142; and a clamping plate 1146, which is connected to the sliding plate 1145.

[0078] In this technical solution, the structure of the abutment unit 114 is further provided. The abutment unit 114 may include a through groove 1141, a fixing plate 1142, a screw 1143, a handwheel 1144, a sliding plate 1145, and a clamping plate 1146. One end of the screw 1143 is connected to the handwheel 1144, and the other end is threadedly connected to the sliding plate 1145. By rotating the handwheel 1144, the screw 1143 can be driven to rotate, thereby driving the sliding plate 1145 to move closer to or away from the slide block 112. The sliding plate 1145 can then drive the clamping plate 1146 to move, ensuring that the clamping plate 1146 can abut against the inner wall of the mine drainage ditch, thereby fixing the mine drainage ditch water level real-time monitoring device and improving the reliability of the device.

[0079] like Figure 6 As shown, in one feasible embodiment, the base assembly 110 further includes: a sliding stop 115 disposed at the end of the slide rod 113; and an anti-slip pad 116 disposed on the side of the clamping plate 1146 facing the base 111.

[0080] In this technical solution, the base assembly 110 may further include a sliding stop 115 and an anti-slip pad 116. The sliding stop 115 limits the adjustment stroke of the slide rod 113, preventing the slide block 112 from detaching from the base 111. The anti-slip pad 116 increases the friction between the clamping plate 1146 and the inner wall of the mine drainage ditch, making the device work more reliably.

[0081] like Figure 4 and Figure 5 As shown, in one feasible embodiment, the mine drainage ditch water level real-time monitoring device further includes a first locking assembly 160, which is used to lock the lifting column 130. The first locking assembly 160 includes: a plurality of limiting holes arranged along the height direction of the lifting column 130; a toothed groove 161 arranged along the height direction of the column 120; a pull rod 162 and an anti-detachment block 163, wherein the pull rod 162 is used to be inserted into the limiting holes to limit the lifting column 130, and the anti-detachment block 163 is arranged on the lifting column 130. Between the lowering column 130 and the upright column 120; a return spring 164, which is sleeved on the pull rod 162; a toothed block 165, which is disposed on the pull rod 162 and is used to engage with the toothed groove 161; wherein, when the toothed block 165 engages with the toothed groove 161 and the pull rod 162 is inserted into the limiting hole, the lifting column 130 is locked; when the pull rod 162 overcomes the elastic force of the return spring 164, the toothed block 165 disengages from the toothed groove 161, and the pull rod 162 disengages from the limiting hole, the lifting column 130 is unlocked.

[0082] In this technical solution, the real-time water level monitoring device for mine drainage ditches may also include a first locking component 160, which can lock the lifting column 130 to prevent the lifting column 130 from falling unexpectedly, thereby further ensuring the reliability of continuous operation of the device.

[0083] In this technical solution, the structure of the first locking assembly 160 is further provided. The first locking assembly 160 may include multiple limiting holes, toothed grooves 161, a pull rod 162, an anti-detachment block 163, a return spring 164, and toothed blocks 165. Based on this, during the use of the real-time water level monitoring device in the mine drainage ditch, the pull rod 162 can be pulled out first. The pull rod 162 overcomes the elastic force of the return spring 164, and the pull rod 162 disengages through the limiting holes. Then, the lifting column 130 is controlled to rise and fall. After adjusting to the desired position, release the pull rod 162. Under the elastic force of the return spring 164, the pull rod 162 is inserted into the limiting hole, while the toothed block 165 engages with the toothed groove 161. The toothed groove 161 and the toothed block 165 can lock the pull rod 162 to prevent the pull rod 162 from shifting in height. Since the pull rod 162 is inserted into the limiting hole, the lifting column 130 can be locked, preventing the lifting column 130 from falling unexpectedly and improving the reliability of the device.

[0084] In one feasible implementation, the mine drainage ditch water level real-time monitoring device further includes a second locking assembly for locking the lifting column 130. The second locking assembly includes: multiple first pin holes formed on the lifting column 130; multiple second pin holes formed on the column 120; and a pin that passes through the first and second pin holes to lock the lifting column 130. Therefore, after the lifting column 130 is adjusted to the expected height, the pin passing through the first and second pin holes can also effectively lock the lifting column 130.

[0085] like Figures 1 to 3 As shown, in one feasible embodiment, the mine drainage ditch water level real-time monitoring device further includes: a fixing ring 170, which is connected to the electrical control box 140 by a connecting bolt 190, and is used to be sleeved on the lifting column 130; and a fastening bolt 180, which is used to lock the fixing ring 170.

[0086] In this technical solution, a connection method between the electrical control box 140 and the lifting column 130 is further provided. The real-time water level monitoring device for the mine drainage ditch can also include a fixing ring 170, which can be fixedly connected to the electrical control box 140 by connecting bolts 190. The fixing ring 170 is then placed on the lifting column 130, and then the fixing ring 170 is locked by fastening bolts 180, which can fix the fixing ring 170 on the lifting column 130, making the fixing of the electrical control box 140 more reliable, reducing the probability of the electrical control box 140 falling, and ensuring the reliability of the device operation.

[0087] like Figure 3As shown, in one feasible embodiment, the mine drainage ditch water level real-time monitoring device further includes: an anti-tipping component 200, which is connected to the side of the lifting column 130 away from the electrical control box 140, and is used to apply stress to the lifting column 130 to balance the weight of the electrical control box 140.

[0088] In this technical solution, considering that the connection between the electrical control box 140 and the lifting column 130 may cause an imbalance in the force on the lifting column 130, posing a risk of tipping over, the real-time water level monitoring device for mine drainage ditches may also include an anti-tipping component 200. By connecting the anti-tipping component 200 to the side of the lifting column 130 away from the electrical control box 140, stress is applied to the lifting column 130 to balance the weight of the electrical control box 140, thereby reducing or eliminating the probability of the lifting column 130 tipping over, further improving the reliability of the device operation, and making it particularly suitable for long-term, continuous monitoring of the water level in mine drainage ditches.

[0089] like Figure 3 As shown, in one feasible embodiment, the anti-tipping component 200 includes: a first pull ring 201, which is disposed on the side of the lifting column 130 opposite to the electrical control box 140; a second pull ring 202, which is sleeved on the first pull ring 201; and a cable reel unit 203, which is connected to the base 111, and the cable 2034 of the cable reel unit 203 is connected to the second pull ring 202 for tightening the lifting column 130.

[0090] In this technical solution, the structure of the anti-tipping component 200 is further provided. The anti-tipping component 200 may include a first pull ring 201, a second pull ring 202 and a cable reel unit 203. The lifting column 130 can be pulled by the cable 2034 of the cable reel unit 203, the first pull ring 201 and the second pull ring 202, which can reduce the probability of the lifting column 130 bending or tipping over and ensure the reliability of the device.

[0091] like Figure 3 As shown, in one feasible embodiment, the coil unit 203 includes: a fixing block 2031, which is disposed on the base 111; a coil 2032, which is connected to the fixing block 2031; a handle 2033, which passes through the fixing block 2031 and is connected to the coil 2032 for driving the coil 2032 to rotate; and a cable 2034, which is wound on the coil 2032, with one end of the cable 2034 connected to the second pull ring 202.

[0092] In this technical solution, the structure of the cable reel unit 203 is further provided. The cable reel unit 203 may include a fixing block 2031, a cable reel 2032, a handle 2033, and a cable 2034. The handle 2033 drives the cable reel 2032 to rotate, and the cable reel 2032 can tighten and loosen the cable 2034. When the cable 2034 is tightened, stress can be applied to the lifting column 130, which can reduce the probability of deformation of the lifting column 130.

[0093] It is understandable that the handle 2033 can be locked onto the fixing block 2031. There can be two fixing blocks 2031, and the coil 2032 can be set between the two fixing blocks 2031, and the coil 2032 can rotate relative to the fixing block 2031.

[0094] like Figures 1 to 3 As shown, in one feasible embodiment, the mine drainage ditch water level real-time monitoring device further includes a support block 210, which is disposed at the base of the column 120 and connected to the base assembly 110. This arrangement increases the connection strength between the column 120 and the base assembly 110, reducing the probability of deformation and tipping of the column 120.

[0095] The operation method of the real-time monitoring device for water level in mine drainage ditches provided in this application embodiment is as follows:

[0096] S1. Pull the slide block 112, which will cause the slide rod 113 and the sliding block 115 to slide together along the inside of the chute, thereby adjusting the distance between the two slide blocks 112. This allows the specific length between the two slide blocks 112 to be adjusted according to the width of the mine drainage ditch.

[0097] S2. When the distance between the two slide blocks 112 is adapted to the width of the mine drainage ditch, place the two slide blocks 112 and the base 111 on the top of the mine drainage ditch, with the two slide blocks 112 located on both sides of the mine drainage ditch and the base 111 located directly above the mine drainage ditch.

[0098] S3. By rotating the screw 1143 through the two handwheels 1144, the two sliding plates 1145 are driven to slide away from each other along the two through slots 1141, thereby driving the two clamping plates 1146 to move away from each other, so that the two clamping plates 1146 are pressed against the inner side of the mine drainage ditch respectively. The anti-slip pad 116 can increase the pressing friction between the clamping plates 1146 and the mine drainage ditch, thus completing the connection and fixation work between the entire device and the mine drainage ditch.

[0099] S4. By pulling rod 162, pull tooth block 165 to separate tooth block 165 from tooth groove 161 and stop meshing;

[0100] S5. Slide the lifting column 130 upward to adjust the position of the electrical control box 140 and the water level sensor 150;

[0101] S6. After the lifting column 130 rises to its maximum height, the water level sensor 150 is placed into the mine drainage ditch.

[0102] S7, the push rod 162, the tooth block 165 is no longer under force, the spring rebounds, driving the anti-disengagement block 163, the connecting rod and the tooth block 165 to reset, thereby making the tooth block 165 mesh with the top of the tooth groove 161, thereby fixing the position of the lifting column 130.

[0103] S8. Turn the handle 2033 clockwise to drive the coil 2032 to rotate clockwise in sync. During this process, the cable 2034 is in the unwinding state until the handle 2033 is no longer threadedly connected to one of the fixing blocks 2031.

[0104] S9. Turn the handle 2033 counterclockwise to drive the coil 2032 to rotate synchronously, so that the cable 2034 is wound around the outer surface of the coil 2032.

[0105] S10. When the cable 2034 is about to be tightened, align the handle 2033 with the threaded hole of one of the fixing blocks 2031, and continue to turn the handle 2033 counterclockwise to tighten the cable 2034 completely. The handle 2033 is threadedly connected to one of the fixing blocks 2031, so that the cable reel 2032 is fixed.

[0106] S11. Complete the installation and commissioning of the real-time monitoring device for the mine drainage ditch water level, and begin real-time monitoring of the water level in the mine drainage ditch.

[0107] The real-time monitoring device for water level in mine drainage ditches provided in this application embodiment has at least the following beneficial effects:

[0108] 1) Through the meshing structure of the lifting column 130 with the tooth groove 161 and tooth block 165, combined with the spring reset mechanism, the height of the lifting column 130 can be quickly adjusted and arbitrarily fixed to adapt to the depth requirements of different mine drainage ditches. The storage function of the lifting column 130 facilitates the quick disassembly or transportation of the device, improving deployment flexibility.

[0109] 2) The mechanical design of the linkage block 165 of the pull rod 162, the connecting rod and the return spring 164 allows the height adjustment to be unlocked in a single step, making the operation intuitive and efficient;

[0110] 3) The taut cable 2034 provides a backward pulling force to the lifting column 130, thereby greatly improving the stability of the lifting column 130 after it is raised and fixed, and preventing the lifting column 130 from shifting due to the gravity pull of the electrical control box 140.

[0111] 4) The sliding linkage mechanism of slide block 112 and slide rod 113 realizes stepless adjustment of the device width. It can quickly match the trench width without disassembly and reassembly. After the base 111 is positioned by moving slide block 112, only four fixing bolts need to be tightened to complete the installation. This simplifies the traditional process of requiring customized brackets or complex assembly. When it is necessary to move or disassemble, the whole device can be moved by simply loosening the bolts, which significantly improves the deployment efficiency of equipment in complex mining environments.

[0112] 5) By adjusting the position of the slide block 112, the base 111 is centered directly above the drainage ditch, ensuring that the water level sensor 150 is vertically projected into the center area of ​​the ditch. This position avoids the turbulent water flow area or the edge siltation area near the ditch wall, and can obtain more representative water level data.

[0113] 6) By using screw 1143 in conjunction with clamping plate 1146, rotating screw 1143 can drive clamping plate 1146 to move, so that clamping plate 1146 is squeezed against the inner side of the drainage ditch, thus achieving the purpose of quickly fixing the device. Compared with the traditional method of fixing with bolts, this method does not require pre-drilling holes for bolt fixing, so its installation is more convenient and faster.
