This not only requires significant manpower and time but also results in low installation efficiency. When a part of the drainage ditch is damaged, the entire ditch needs to be replaced, leading to high replacement costs. Furthermore, traditional drainage ditches often use direct connections or simple slotted splicing, which can easily cause misalignment or warping at the joints, resulting in mine water leakage and adversely affecting the stability of the roadway and normal coal mine production operations. Utility Model Content

[0003] To address the issues of needing to replace the entire drainage ditch when a section is damaged and the easy leakage of mine water from the joints, this utility model aims to provide a combined coal mine roadway drainage ditch.

The cooperation between the connecting block and the placement groove is used to splice drainage ditch one and drainage ditch two. A quick-release mechanism is provided at the top of the connecting block, a sealing strip is provided at the splice of drainage ditch one and drainage ditch two, and a pressing mechanism is provided at the top of drainage ditch two for pressing the sealing strip; the quick-release mechanism includes a support plate one, which is fixedly connected to drainage ditch one, and a box is fixedly installed at the bottom end of support plate one. A screw rod one is threadedly connected to the middle of the box. The screw rod one is threadedly connected to support plate one, and the bottom end of screw rod one is rotatably mounted. The device is equipped with a lowering block 1. Connecting rods are rotatably mounted on both sides of the lowering block 1 via pins. A moving block is rotatably mounted on the end of the connecting rod away from the lowering block 1 via a pin. An insert rod is fixedly mounted on the end of the moving block away from the connecting rod. The insert rod is slidably connected to the housing. Fixing grooves 1 and 2 are provided on both sides of drainage channel 1 for use with the insert rods. A sliding rail structure, consisting of a slider and a guide rail, is provided at the bottom of the moving block. The slider is fixedly connected to the moving block, and the guide rail is fixedly connected to the upper surface of the inner wall of the housing. Two symmetrically distributed limiting plates are fixedly installed inside the housing. The lowering block 1 slides around the outside of the limiting plates. Installation grooves are provided at the top edge of the connecting block and on the top of drainage channel 2 near the placement groove. These installation grooves are used to place sealing strips.

[0005] Preferably, the clamping mechanism includes a second support plate, a second screw threadedly connected to the middle of the second support plate, a second lowering block rotatably mounted at the bottom of the second screw, two symmetrically distributed connecting plates at the bottom of the second lowering block, the connecting plates being V-shaped, a fixed seat rotatably mounted at the middle of the connecting plate via a pin, the fixed seat being fixedly connected to the second drainage ditch, a clamping plate rotatably mounted at the bottom of the connecting plate via a pin, and sliding grooves on both sides of the second lowering block, the top of the connecting plate sliding in the sliding groove via a pin; two symmetrically distributed I-beams fixedly mounted at the top of the second lowering block, the I-beams being slidably connected to the second support plate; a first rotating wheel fixedly mounted at the top of the first screw, a second rotating wheel fixedly mounted at the top of the second screw, and several uniformly distributed trapezoidal blocks fixedly mounted on the outside of both the second and first rotating wheels; the end of the clamping plate near the second drainage ditch is triangular.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. This application sets up a quick-release mechanism. The downward movement of the lower block one causes the connecting rod to change, pushing the slider at the bottom of the moving block to slide on the guide rail. At the same time, the insertion rod moves linearly in the box. As the lower block one continues to move downward, the insertion rod will eventually be locked into the fixing groove one and fixing groove two, thereby realizing the quick splicing and fixing between drainage channel one and drainage channel two, improving installation efficiency, realizing the replacement of a certain part of the drainage channel, and reducing costs.

This application, by setting up a clamping mechanism, causes the pin at the top of the connecting plate to slide from the outside to the inside in the groove during the downward movement of the second lower block. The middle pin rotates in the fixed seat, causing the clamping plate to move closer to the sealing strip, thereby clamping the sealing strip. This ensures that the sealing strip fits tightly with the joint between drainage channel one and drainage channel two, preventing mine water leakage and affecting the stability of the roadway and the normal production operation of the coal mine.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figure 1-8As shown, this utility model provides a combined coal mine roadway drainage ditch, including a drainage ditch structure 1. The drainage ditch structure 1 includes a first drainage ditch 11 and a second drainage ditch 12. A connecting block 13 is installed at one end of the first drainage ditch 11 near the second drainage ditch 12. A placement groove 14 is provided at the top edge of the second drainage ditch 12 to cooperate with the connecting block 13. The cooperation between the connecting block 13 and the placement groove 14 is used to splice the first drainage ditch 11 and the second drainage ditch 12. A quick-release mechanism 2 is provided at the top of the connecting block 13. A sealing strip 3 is provided at the splice of the first drainage ditch 11 and the second drainage ditch 12. A pressing mechanism 4 is provided at the top of the second drainage ditch 12 to press the sealing strip 3.

[0022] The quick-release mechanism 2 includes a support plate 20, which is fixedly connected to a drainage ditch 11. A housing 21 is fixedly installed at the bottom of the support plate 20. A screw 22 is threadedly connected to the middle of the housing 21. The screw 22 is threadedly connected to the support plate 20. A lowering block 23 is rotatably installed at the bottom of the screw 22. Connecting rods 24 are rotatably installed on both sides of the lowering block 23 via pins. A moving block 25 is rotatably installed at the end of the connecting rod 24 away from the lowering block 23 via a pin. A rod 26 is fixedly installed at the end of the movable block 25 away from the connecting rod 24. The rod 26 is slidably connected to the box 21. Fixing grooves 27 that cooperate with the rod 26 are opened on both sides of the drainage channel 11. Fixing grooves 28 that cooperate with the rod 26 are opened on both sides of the drainage channel 22. A slide rail structure 29 is provided at the bottom of the movable block 25. The slide rail structure 29 is composed of a slider and a guide rail. The slider is fixedly connected to the movable block 25. The guide rail is fixedly connected to the upper surface of the inner wall of the box 21.

[0023] By setting up the quick-release mechanism 2, the downward movement of the first moving block 23 changes the connecting rod 24, pushing the slider at the bottom of the moving block 25 to slide on the guide rail. At the same time, the insertion rod 26 moves linearly inside the housing 21. As the first moving block 23 continues to move downward, the insertion rod 26 will eventually be inserted into the first fixing groove 27 and the second fixing groove 28, thereby realizing the quick splicing and fixing between the first drainage channel 11 and the second drainage channel 12, improving the installation efficiency, realizing the replacement of a certain part of the drainage channel, and reducing costs. It should be noted that the end of the first drainage channel 11 away from the second drainage channel 12 is equipped with a pressing mechanism 4, and the top is provided with a placement groove 14. The end of the second drainage channel 12 away from the first drainage channel 11 is equipped with a connecting block 13, and the quick-release mechanism 2 is installed on the connecting block 13, thereby realizing the splicing between multiple drainage channels. The drainage direction flows from the second drainage channel 12 to the first drainage channel 11.

[0024] The clamping mechanism 4 includes a second support plate 41, a second screw 42 threadedly connected to the middle of the second support plate 41, a second lowering block 43 rotatably mounted at the bottom end of the second screw 42, and two symmetrically distributed connecting plates 44 at the bottom end of the second lowering block 43. The connecting plates 44 are V-shaped, and a fixed seat 45 is rotatably mounted at the middle of the connecting plates 44 via a pin. The fixed seat 45 is fixedly connected to the second drainage ditch 12. A clamping plate 46 is rotatably mounted at the bottom end of the connecting plates 44 via a pin. Sliding grooves 47 are provided on both sides of the second lowering block 43, and the top ends of the connecting plates 44 slide in the sliding grooves 47 via pins. By setting the clamping mechanism 4, during the downward movement of the second lower block 43, the pin at the top of the connecting plate 44 slides from the outside to the inside in the slide groove 47, and the middle pin rotates in the fixed seat 45, so that the clamping plate 46 moves closer to the sealing strip 3, thereby clamping the sealing strip 3 and making the sealing strip 3 fit tightly with the joint of the first drainage ditch 11 and the second drainage ditch 12, thus preventing mine water leakage and affecting the stability of the roadway and the normal production operation of the coal mine. The two sides of the second lower block 43 and the middle of the vertical groove are provided with vertical grooves to facilitate the sliding of the pin at the top of the connecting plate 44 in the slide groove 47.

[0025] Two symmetrically distributed limiting plates are fixedly installed inside the housing 21, and the lower moving block 23 is slidably sleeved on the outside of the limiting plates. By setting the limiting plates, the lower moving block 23 is limited, so as to prevent the lower moving block 23 from rotating with the screw 22 and affecting the movement of the lower moving block 23.

[0026] Two symmetrically distributed I-beam plates 48 are fixedly installed at the top of the second lower block 43. The I-beam plates 48 are slidably connected to the second support plate 41. By setting the I-beam plates 48, the second lower block 43 is limited, so as to prevent the second lower block 43 from rotating with the second screw 42 and affecting the movement of the second lower block 43.

[0027] The screw 42 is provided with a telescopic rubber sleeve 49. The top end of the rubber sleeve 49 is fixedly connected to the bottom end of the support plate 41, and the bottom end of the rubber sleeve 49 is fixedly connected to the top end of the lower moving block 43. By setting the rubber sleeve 49, the screw 42 is protected, and dust is prevented from being absorbed into the thread groove of the screw 42 during the use of the drainage ditch structure 1, which would affect the rotation of the screw 42.

[0028] A rotating wheel is fixedly installed at the top of screw 22, and a rotating wheel is fixedly installed at the top of screw 42. Several evenly distributed trapezoidal blocks are fixedly installed on the outside of both rotating wheel 2 and rotating wheel 1. By setting rotating wheel 1, screw 22 is driven to rotate, causing the lowering block 23 to move. The same applies to rotating wheel 2, which drives screw 42 to rotate, causing the lowering block 43 to move. The trapezoidal blocks on the outside of rotating wheel 1 and rotating wheel 2 increase the friction between the hand and rotating wheel 1 and rotating wheel 2, making it easier to rotate rotating wheel 1 and rotating wheel 2.

[0029] The end of the clamping plate 46 near the drainage ditch 12 is triangular; this prevents the clamping plate 46 from blocking the discharge of mud and sand during the use of the drainage ditch structure 1, thus avoiding blockage of the drainage ditch structure 1 and affecting drainage.

[0030] Installation slots are provided at the top edge of the connecting block 13 and the top of the drainage channel 2 12 near the placement slot 14. The installation slots are used to place the sealing strip 3. By setting the installation slots, it is easy to know where the sealing strip 3 needs to be installed on the connecting block 13 and the drainage channel 2 12.

[0031] Working principle: In actual use, when splicing drainage ditch 11 and drainage ditch 22, firstly, the quick-release mechanism 2 is fixed to the connecting block 13 with bolts. Then, a portion of the sealing strip 3 is first installed and embedded into the mounting groove of drainage ditch 11. Next, the connecting block 13 at one end of drainage ditch 11 is placed into the placement groove 14 at one end of drainage ditch 22, and the remaining portion of the sealing strip 3 is embedded into the mounting groove of drainage ditch 22. After pressing the sealing strip 3 and initially splicing it, the first rotating wheel is rotated to drive... When screw 22 rotates, the lowering block 23 is limited by the limiting plate. The rotation of screw 22 causes the lowering block 23 to move vertically downward. The downward movement of the lowering block 23 causes the connecting rod 24 to change, which in turn pushes the slider at the bottom of the moving block 25 to slide on the guide rail. At the same time, the insertion rod 26 moves linearly inside the housing 21. As the lowering block 23 continues to move downward, the insertion rod 26 will eventually be inserted into the fixing groove 27 and the fixing groove 28, thereby realizing the rapid splicing and fixing between drainage channel 11 and drainage channel 22.

[0032] After the above operations are completed, rotate the second rotating wheel to drive the second screw 42 to rotate. Since the second lowering block 43 is limited by the I-plate 48, the rotation of the second screw 42 will drive the second lowering block 43 to move vertically downward. During the downward movement of the second lowering block 43, the rubber sleeve 49 is stretched. At the same time, the pin at the top of the connecting plate 44 slides from the outside to the inside along the slide groove 47, and the middle pin will rotate in the fixed seat 45. This series of linkages causes the pressing plate 46 to gradually approach the sealing strip 3 until the pressing plate 46 presses the sealing strip 3 at the joint between the sealing strip 3 and the first drainage channel 11 and the second drainage channel 12.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
