Description

Technical Field

[0001] This utility model relates to the field of coal mine detection technology, and in particular to a coal mine underground water seepage detection device. Background Technology

[0002] Coal mines are areas where humans extract coal resources in coal-rich areas, generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, underground tunnels are typically dug to extract the coal; this is called an underground coal mine. When the coal seam is very close to the surface, the surface soil is typically stripped away to extract the coal; this is called an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines.

[0003] During mining operations, underground mines need to detect water seepage. In case of abnormal seepage, workers need to be evacuated immediately to prevent mine collapse and endangerment. However, in existing technologies, most water level detection is done directly through sensors. This can easily lead to sensor probe contamination in the mine. Furthermore, as the mine moves underground, large amounts of mud, sand, and coal ash can affect the normal operation of the sensors. Therefore, a coal mine underground water seepage detection device is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a coal mine underground water seepage detection device, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of this utility model provides a coal mine underground water seepage detection device, including a cylinder. A circular plate is slidably connected to the inner wall of the cylinder. A shielding plate is fixedly connected to the edge of the bottom surface of the circular plate. The shielding plate is hollow. A circular frame is fixedly connected to the bottom surface of the inner wall of the cylinder. A cavity is left inside the circular frame. A distance is left between the outer wall of the circular frame and the inner wall of the cylinder. The shielding plate is located between the circular frame and the inner wall of the cylinder. Several first holes are opened at the lower part of the outer wall of the cylinder near the circular frame. Several second holes are opened at the position of the outer wall of the circular frame near the first holes. Several limiting clamps are fixedly connected inside the circular frame. The several limiting clamps are grouped in pairs. A floating ball is slidably connected between each group of limiting clamps. An infrared rangefinder is fixedly connected to the top surface of the outer wall of the circular frame near each group of limiting clamps. The output ends of the several infrared rangefinders are respectively facing the several floating balls.

[0006] Preferably, in any of the above embodiments, a conical block is fixedly connected to the bottom of the outer wall of the cylinder.

[0007] The technical effect achieved by adopting the above scheme is that it makes it easier for the cylinder to go deep underground, allowing the cylinder to be more conveniently close to the area being measured, and increasing the flexibility and convenience of using the cylinder.

[0008] Preferably, in any of the above embodiments, a motor is fixedly connected to the top surface of the inner wall of the cylinder, a lead screw is fixedly connected to the output end of the motor, the lead screw is threadedly connected to the circular plate, two limiting rods are fixedly connected to the top of the inner wall of the cylinder, both limiting rods are slidably connected to the circular plate, the ends of the two limiting rods away from the motor pass through the cavity and are fixedly connected to the bottom surface of the inner wall of the cylinder, and the end of the lead screw away from the motor passes through the cavity and is rotatably connected to the bottom surface of the inner wall of the cylinder.

[0009] The technical effect achieved by adopting the above solution is that the motor can drive the lead screw to rotate, providing power for the rotation of the lead screw. At the same time, the circular plate is slidably connected to the two limit rods, which plays a limiting role, so that the circular plate and the baffle can only move up and down. When the lead screw rotates, it can drive the baffle to move up and down.

[0010] Preferably, in any of the above embodiments, the two sides of the baffle plate are slidably connected to the inner wall of the cylinder and the outer wall of the circular frame, respectively, and the first hole and the second hole connect the circular frame to the outside world.

[0011] The technical effect achieved by adopting the above solution is that the sealing performance of the baffle can be increased by using this solution. Water can enter the interior of the circular frame through the first hole and the second hole. The baffle is located between the first hole and the second hole. By adjusting the position of the baffle, the first hole and the second hole can be closed and opened.

[0012] Preferably, in any of the above solutions, the length of the shield is greater than the length of the circular frame.

[0013] The technical effect achieved by adopting the above solution is that the shield can completely cover the circular frame, thereby further increasing the sealing performance of the shield.

[0014] Preferably, in any of the above embodiments, a sealing ring is fixedly connected to the end of the baffle away from the circular plate, and the sealing ring is located between the cylinder and the circular frame.

[0015] The technical effect achieved by adopting the above solution is that it can prevent water from flowing between the circular frame and the cylinder.

[0016] This utility model has the following advantages:

[0017] 1. This coal mine underground water seepage detection device sends a cylinder to the area to be detected. A motor drives a lead screw to rotate. The circular plate and the limiting rod are slidably connected to limit the movement. The rotation of the lead screw can drive the circular plate and the shielding plate to move downwards until the shielding plate moves the sealing ring to the bottom surface of the inner wall of the cylinder. This can prevent mud, sand, coal ash, etc. from entering the inside of the cylinder through the first hole, increasing the sealing of the cylinder. This prevents the dust and sand from damaging the sensor and other parts during the movement of the cylinder underground, making it safer and more practical.

[0018] 2. In this coal mine seepage detection device, when the cylinder reaches the designated position, the motor drives the lead screw to rotate in the opposite direction, causing the baffle plate to move upward. At this time, the first hole and the second hole are connected, and the inner wall of the circular frame is in a state of communication with the outside. When there is water flow nearby, it can enter the inside of the circular frame through the first hole and the second hole. The water flow gathers inside the circular frame, which can lift the floating ball. The distance between the floating ball and the infrared rangefinder can be monitored to detect the seepage situation in the mine. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0026] like Figures 1 to 5As shown, a coal mine seepage detection device includes a cylinder 1. A circular plate 5 is slidably connected to the inner wall of the cylinder 1. A shielding plate 14 is fixedly connected to the edge of the bottom surface of the circular plate 5. The shielding plate 14 is hollow. A circular frame 6 is fixedly connected to the bottom surface of the inner wall of the cylinder 1. A cavity 17 is left inside the circular frame 6. A distance is left between the outer wall of the circular frame 6 and the inner wall of the cylinder 1. The shielding plate 14 is located between the circular frame 6 and the inner wall of the cylinder 1. Several first holes 2 are opened at the lower part of the outer wall of the cylinder 1 near the circular frame 6. Several second holes 13 are opened at the outer wall of the circular frame 6 near the first holes 2. Several limiting clamps 8 are fixedly connected inside the circular frame 6. The limiting clamps 8 are in pairs. A floating ball 7 is slidably connected between each pair of limiting clamps 8. An infrared rangefinder 10 is fixedly connected to the top surface of the outer wall of the circular frame 6 near each pair of limiting clamps 8. The output ends of the infrared rangefinders 10 are respectively facing the floating balls 7.

[0027] As an optional technical solution of this utility model, a conical block 3 is fixedly connected to the bottom of the outer wall of the cylinder 1. By using this solution, the cylinder 1 can be easily inserted into the ground, making it easier for the cylinder 1 to approach the area to be measured, and increasing the flexibility and convenience of using the cylinder 1.

[0028] As an optional technical solution of this utility model, a motor 12 is fixedly connected to the top surface of the inner wall of the cylinder 1, and a lead screw 11 is fixedly connected to the output end of the motor 12. The lead screw 11 is threadedly connected to the circular plate 5. Two limiting rods 4 are fixedly connected to the top of the inner wall of the cylinder 1. Both limiting rods 4 are slidably connected to the circular plate 5. The ends of the two limiting rods 4 away from the motor 12 pass through the cavity 17 and are fixedly connected to the bottom surface of the inner wall of the cylinder 1. The ends of the lead screw 11 away from the motor 12 pass through the cavity 17 and are rotatably connected to the bottom surface of the inner wall of the cylinder 1. By using this solution, the motor 12 can drive the lead screw 11 to rotate, providing power for the rotation of the lead screw 11. At the same time, the circular plate 5 is slidably connected to the two limiting rods 4, which plays a limiting role, so that the circular plate 5 and the baffle plate 14 can only move up and down. When the lead screw 11 rotates, it can drive the baffle plate 14 to move up and down.

[0029] As an optional technical solution of this utility model, the two sides of the baffle plate 14 are slidably connected to the inner wall of the cylinder 1 and the outer wall of the circular frame 6, respectively. The first hole 2 and the second hole 13 connect the circular frame 6 to the outside. By using this solution, the sealing performance of the baffle plate 14 can be increased. Water can enter the interior of the circular frame 6 through the first hole 2 and the second hole 13. The baffle plate 14 is located between the first hole 2 and the second hole 13. By adjusting the position of the baffle plate 14, the effect of closing and opening the first hole 2 and the second hole 13 can be achieved.

[0030] As an optional technical solution of this utility model, the length of the shield 14 is greater than the length of the circular frame 6. By using this solution, the shield 14 can completely cover the circular frame 6, further increasing the sealing performance of the shield 14.

[0031] As an optional technical solution of this utility model, a sealing ring 15 is fixedly connected to the end of the baffle plate 14 away from the circular plate 5. The sealing ring 15 is located between the cylinder 1 and the circular frame 6. By using this solution, water can be prevented from flowing from the position between the circular frame 6 and the cylinder 1.

[0032] The following steps are required when using this coal mine underground water seepage detection device:

[0033] 1) Rotating the lead screw 11 can drive the circular plate 5 and the baffle plate 14 to move downwards until the baffle plate 14 drives the sealing ring 15 to the bottom surface of the inner wall of the cylinder 1.

[0034] 2) When the cylinder 1 reaches the designated position, the motor 12 drives the lead screw 11 to rotate in the opposite direction, which in turn drives the baffle plate 14 to move upward.

[0035] 3) When there is water flow nearby, it can enter the interior of the circular frame 6 through the first hole 2 and the second hole 13, and the water flow will gather inside the circular frame 6.

[0036] In summary, when using the cylinder, the user places it to the area to be detected. The motor 12 drives the lead screw 11 to rotate. The circular plate 5 and the limiting rod 4 are slidably connected to limit the movement. The rotation of the lead screw 11 causes the circular plate 5 and the baffle plate 14 to move downwards until the baffle plate 14 moves the sealing ring 15 to the bottom surface of the inner wall of the cylinder 1. This prevents mud, sand, coal ash, etc., from entering the interior of the cylinder 1 through the first hole 2, increasing the sealing performance of the cylinder 1. This prevents dust and sand from damaging the sensor and other components during the movement of the cylinder 1 underground. This method is safer and more practical. When the cylinder 1 reaches the designated position, the motor 12 drives the lead screw 11 to rotate in the opposite direction, which in turn moves the baffle 14 upward. At this time, the first hole 2 and the second hole 13 are connected, and the inner wall of the circular frame 6 is in a state of communication with the outside. When there is water flow nearby, it can enter the interior of the circular frame 6 through the first hole 2 and the second hole 13. The water flow gathers inside the circular frame 6, which can lift the floating ball 7. The infrared rangefinder 10 monitors the distance between itself and the floating ball 7, which can detect the water seepage in the well.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
