Description

Technical Field

[0001] This utility model belongs to the technical field of coal mine water testing tools, specifically relating to a portable water testing tool for coal mines. Background Technology

[0002] With coal mining, large areas of goaf are formed. After the roof collapses in the goaf, certain spaces are created, and groundwater gradually accumulates in these spaces. Once the water reaches a certain level, it may break through the impermeable layer or cause a sudden water inrush when mining activities are approaching. This is a very serious safety accident in coal mines, which can lead to the flooding of underground roadways and pose a huge threat to the lives of miners. When existing water accumulation detection technology is applied to goaf scenarios, especially when there is a large difference in elevation between the water accumulation in the goaf and the ground, conventional detection methods are difficult to accurately determine the degree of water accumulation. This elevation difference makes it difficult to directly and conveniently obtain data on changes in water depth, and thus it is impossible to accurately grasp the dynamic changes of water accumulation, which greatly increases the difficulty of effectively controlling water accumulation. Utility Model Content

[0003] This utility model provides a portable water measuring tool for coal mines, which solves the problem of inconvenience in measuring the rise of water level when detecting water accumulation.

[0004] This utility model provides the following technical solution: it includes two mounting brackets and a connecting bracket. A limiting rod is provided at the center of the mounting bracket and the connecting bracket. A float is slidably connected to the inner wall of the mounting bracket. The limiting rod passes through the float. A clearance groove is provided on the float. A support block is fixedly connected to the center of the float. A scale rod is slidably connected to the inner wall of the clearance groove. A sliding hole is provided on the outer wall of the connecting bracket. A sliding plate is slidably connected to the inner wall of the sliding hole. An upper fixing plate is fixedly connected to one side of two of the mounting brackets. A lower fixing plate is fixedly connected to one side of the other two mounting brackets. A hinge rod is hinged to the lower fixing plate. A push rod corresponding to the sliding plate is fixedly connected to one side of the hinge rod. A clearance hole matching the hinge rod is provided on the upper fixing plate.

[0005] The limiting rod has a top ring fixedly connected to its outer wall, a rotating ring rotatably connected to its outer wall, a locking rod fixedly connected to its outer wall, and a locking groove that engages with the locking rod on the inner wall of the mounting frame.

[0006] The lower fixing plate has a mounting block fixedly connected to its top end, and one end of the hinge rod is hinged to the mounting block.

[0007] The slide plate has connecting blocks fixedly connected to both ends, and mating blocks that match the connecting blocks are fixedly connected to the upper and lower fixed plates. A guide rod is fixedly connected to the mating block, and the connecting block is slidably connected to the guide rod.

[0008] The mounting frame is fitted with an upper mounting ring and a lower mounting ring on its outer side, and an isolation rod is fixedly connected between the upper mounting ring and the lower mounting ring.

[0009] The upper mounting ring is provided with a baffle above it, and the baffle and the upper mounting ring are connected by a connecting plate. The baffle has a hole at its center for making way for the scale rod.

[0010] The beneficial effects of this utility model are: by sliding the float on the inner wall of the mounting frame, the height of the float can be positioned in conjunction with the sliding plate, upper fixing plate, lower fixing plate and hinge rod, and the depth of the float in the device can be judged in conjunction with the scale rod and support block. Since the float floats on the water surface, the degree of rise can be detected, which is beneficial to the safe production of coal mines and avoids the inconvenience of measuring the rise of water when the height difference between the water position and the ground is large.

[0018] Please see Figures 1-5 The present invention provides the following technical solution: it includes two mounting brackets 1 and a connecting bracket 11. A limiting rod 12 is provided at the center of the mounting brackets 1 and the connecting bracket 11. A float 13 is slidably connected to the inner wall of the mounting bracket 1. The limiting rod 12 passes through the float 13. A clearance groove 132 is provided on the float 13. A support block 131 is fixedly connected to the center of the float 13. A scale rod 32 is slidably connected to the inner wall of the clearance groove 132. A sliding hole 14 is provided on the outer wall of the connecting bracket 11. A sliding plate 2 is slidably connected to the inner wall of the sliding hole 14. An upper fixing plate 22 is fixedly connected to one side of the two mounting brackets 1. A lower fixing plate 23 is fixedly connected to one side of the other two mounting brackets 1. A hinge rod 25 is hinged to the lower fixing plate 23. A push rod 26 corresponding to the sliding plate 2 is fixedly connected to one side of the hinge rod 25. A clearance hole 221 matching the hinge rod 25 is provided on the upper fixing plate 22.

[0019] In this implementation scheme: two mounting brackets 1 are connected and fixed by connecting brackets 11, fixing the device in a fixed position on the accumulated water, so that the bottom of the device is submerged in the water. The mounting brackets 1 are used to limit the float 13, so that the float 13 is clamped by the mounting brackets 1 on the left and right sides. The outer wall of the float 13 matches the inner wall of the mounting bracket 1. The float 13 can be made of a material that can float on the water surface, so that it can float according to the water level. It is limited by the float 13, so that it is within the float 13 and changes height synchronously with the rise of the accumulated water. When it is necessary to observe the rise of the accumulated water level, when the accumulated water... When the ground has a certain height difference, making it inconvenient to detect the position of the float 13 between the mounting brackets 1, the upper fixing plate 22 and the lower fixing plate 23 installed on one side of the mounting bracket 1 can be aligned vertically. The top of the hinge rod 25 hinged on the lower fixing plate 23 passes through the clearance hole 221 opened on the upper fixing plate 22, allowing the angle of the hinge rod 25 to be directly adjusted at the top of the device. When the device is in use, the upper fixing plate 22 is in the top position, and the lower fixing plate 23 is in the water, making it easy to directly control the hinge rod 25 and push the two hinge rods 25 towards the connecting frame 11. The movement allows the push rod 26, which is fixedly connected to one side of the hinge rod 25, to be supported on the side of the sliding plate 2, which is slidably connected to the inner wall of the sliding hole 14 on the outer wall of the limiting rod 12. This allows the push rod 26 to push the mounting block 24, thereby allowing one end of the sliding plate 2 to apply pressure to the outer wall of the float 13, generating a large frictional force between the sliding plate 2 and the outer wall of the float 13. This allows the float 13 to be directly supported and fixed, facilitating the detection of the water level height of the float 13. The scale rod 32 can slide on the inner wall of the relief groove 132 on the limiting rod 12, allowing the scale rod to... The bottom of the scale rod 32 can be supported on the top of the support block 131 fixedly connected to the inner wall of the float 13. The scale line set on the outer wall of the scale rod 32 can be used to determine the depth of the scale rod 32 inserted into the connecting frame 11. This allows the device to record the position data of the float 13 based on the previous insertion of the scale rod 32 into the relief groove 132. The difference between the two measurements can be used to calculate the rise in water level during the two measurements. This is beneficial to the safe production of coal mines and avoids the inconvenience of measuring the rise in water level when the difference between the water level and the ground height is large.

[0020] A top ring 121 is fixedly connected to the outer wall of the limiting rod 12. A rotating ring 122 is rotatably connected to the outer wall of the top ring 121. A locking rod 123 is fixedly connected to the outer wall of the rotating ring 122. A slot 124 is provided on the inner wall of the mounting bracket 1 to engage with the locking rod 123. The top ring 121 fixedly connected to the outer wall of the limiting rod 12 can be positioned at the top of the limiting rod 12. At this time, the top ring 121 can drive the limiting rod 12 to rotate. The bottom of the limiting rod 12 can be threadedly connected to the bottom plate between the mounting bracket 1 and the connecting bracket 11, which are located at the bottom, so that it can be easily installed. The rotating ring 122 can be supported and engaged in the inner wall of the slot 124 by the locking rod 123, so that the limiting rod 12 can be supported and limited, and the limiting rod 12 is positioned in the middle section between the mounting brackets 1. This ensures that after the float 13 is penetrated by the limiting rod 12, it can be limited by the connecting bracket 11 and move up and down.

[0021] A mounting block 24 is fixedly connected to the top of the lower fixed plate 23, and one end of the hinge rod 25 is hinged to the mounting block 24. The mounting block 24 fixedly connected to the top of the lower fixed plate 23 can connect to the bottom end of the hinge rod 25, so that the bottom end of the hinge rod 25 is hinged between the mounting blocks 24, thereby facilitating the adjustment of the position of one end of the push rod 26. When the slide plate 2 needs to restrain the height of the float 13, the position of the float 13 is supported and fixed, and the bottom end of the scale rod 32 can be supported on the support block 131 to detect the rise in water level.

[0022] Connecting blocks 28 are fixedly connected to both ends of the slide plate 2. Matching docking blocks 29 are fixedly connected to the upper fixed plate 22 and the lower fixed plate 23. Guide rods 291 are fixedly connected to the docking blocks 29. The connecting blocks 28 and the guide rods 291 are slidably connected. The connecting blocks 28 fixedly connected to both ends of the slide plate 2 correspond to the docking blocks 29. The connecting blocks 28 are limited by the guide rods 291 fixedly connected to the docking blocks 29, so that the slide plate 2 can slide on the inner wall of the sliding hole 14. The slide plate 2 can apply pressure to the float ball 13 relatively perpendicularly, so that the height of the float ball 13 will not change.

[0023] An upper mounting ring 21 and a lower mounting ring 211 are fitted on the outer side of the mounting frame 1. An isolation rod 27 is fixedly connected between the upper mounting ring 21 and the lower mounting ring 211. The upper mounting ring 21 and the lower mounting ring 211 fitted on the outer side of the mounting frame 1 can be located on the outside of the device. They are connected to each other by the isolation rod 27, so that the isolation rod 27 can block coal particles, gangue, wood, support materials, etc. in the water, so as to avoid affecting the floating height of the float 13 and thus affecting the water level rise detection.

[0024] A baffle 3 is provided above the upper mounting ring 21. The baffle 3 and the upper mounting ring 21 are connected by a connecting plate 33. A socket 31 for making way for the scale rod 32 is provided at the center of the baffle 3. The baffle 3 above the upper mounting ring 21 can protect the device from being above it. The baffle 3 makes way for the scale rod 32 through the socket 31. The baffle 3 is fixed by the connecting plate 33, so that the baffle 3 is stable on the mounting bracket 1.

[0025] The working principle and usage process of this utility model are as follows: During use, the float 13 slides between the mounting brackets 1, and the limiting rod 12 passes through the float 13. At this time, the clearance groove 132 opened on the limiting rod 12 can install the scale rod 32, so that the bottom end of the scale rod 32 can be vertically supported on the support block 131 installed inside the float 13. At the same time, when the scale rod 32 is connected with the float 13, the top position of the hinge rod 25 at the top of the device can be pushed to rotate the hinge rod 25. The push rod 26 applies a pushing force to one side of the slide plate 2, so that the slide plate 2 slides on the inner wall of the sliding hole 14, supporting and positioning the height of the float 13. This allows the depth of the baffle 3 in the device to be detected. By comparing the depths of the baffle 3 detected on the front and rear sides, the difference is taken. This device is beneficial to the safe production of coal mines and avoids the inconvenience of measuring the rise of water accumulation when the height difference between the water accumulation position and the ground is large.
