Description

Technical Field

[0001] The utility model relates to the technical field related to water accumulation monitoring, in particular to a mine water accumulation monitoring device. Background Art

[0002] In order to avoid safety accidents caused by water accumulation, corresponding alarm monitoring equipment is required to be installed at the underground site.

[0003] The utility model patent with announcement number CN218545849U discloses a mine water accumulation monitoring device, which belongs to the technical field related to mine water accumulation monitoring. It solves the problem that in the prior art, accumulated water enters the interior of the water level shell through the lower end opening of the water level shell, but in actual application, the opening of the water level shell is easily blocked by debris in the water, resulting in the inability of accumulated water to enter the interior of the water level shell, and the floating block cannot rise, making it impossible to accurately judge the water level. Through the cooperation between the main rod and the floating block, the floating block is exposed to the outside and directly contacts with the accumulated water outside, so it can accurately follow the rise of the water level of the accumulated water.

[0004] However, the above patents still have shortcomings: this patent, through the cooperation between the main rod and the float block, realizes that the float block is exposed to the outside and directly contacts the accumulated water outside, and can accurately follow the rising water level of the accumulated water, but it does not have the ability to accurately monitor the depth of the accumulated water inside the mine, resulting in the staff being unable to know the specific depth of the accumulated water inside the mine; this patent, through the cooperation between the conductive ring and the contact, realizes that when the conductive ring contacts the contact, it can be triggered, so that the sound and light alarm can be alarmed. The air inside the mine is relatively humid, and electrical components are prone to short circuit when used in a humid environment. Since more electrical components are used in this patent, the probability of short circuit damage to the device will also increase accordingly. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a mine water accumulation monitoring device to solve the problem raised in the above background technology that the depth of water accumulation inside the mine cannot be accurately monitored, resulting in the staff being unable to know the specific depth of water accumulation inside the mine.

[0006] The technical solution of the utility model is:

[0007] A mine water accumulation monitoring device comprises: a vertical rail; a counterweight base is fixedly connected to the bottom of the vertical rail, two detection boxes are sleeved on the outer surface of the vertical rail near the counterweight base, and a limit plate for controlling the movement of the detection boxes is fixedly connected to the top of the vertical rail; buoyancy mechanisms for rising and falling according to the water level are arranged on both sides of the two detection boxes; and roller mechanisms for detecting the movement of the detection boxes are arranged inside the detection boxes.

[0008] Preferably, the buoyancy mechanism comprises: connecting rods are fixedly connected to both sides of the two detection boxes, and the ends of the connecting rods away from the detection boxes are fixedly connected to the vertical rods; and the bottom ends of the vertical rods are fixedly connected to the buoyancy balls.

[0009] Preferably, the roller mechanism includes: a first rotating shaft rotatably connected to one side of the interior of the detection box, a first detection wheel is fixedly connected to the outer surface of the first rotating shaft located inside the detection box, a second rotating shaft is rotatably connected to the side of the detection box away from the first rotating shaft, and a second detection wheel is fixedly connected to the outer surface of the second rotating shaft located inside the detection box; one end of the first rotating shaft and the second rotating shaft both pass through the detection box and extend to the angle sensor, the first rotating shaft and the second rotating shaft are respectively fixedly connected to the detection ends of the angle sensor, and the angle sensor is fixedly connected to the detection box.

[0010] Preferably, a controller is fixedly connected to one side of the detection box away from the rotation angle sensor, the rotation angle sensors are electrically connected to the controllers respectively, and both controllers are externally connected to a computer.

[0011] Preferably, outer surfaces of the first detection wheel and the second detection wheel are both provided with damping pads, and the damping pads are fixedly connected to the first detection wheel and the second detection wheel respectively.

[0012] Preferably, the counterweight base is provided with a rubber pad near the buoyancy ball, and the rubber pad is fixedly connected to the counterweight base.

[0013] Preferably, both sides of the vertical rail are fixedly connected with structural plates, and the bottom ends of the structural plates are fixedly connected to the counterweight base.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] Firstly, the utility model can drive the roller structure while the buoyancy mechanism drives the detection box to rise according to the water level through the coordination of the vertical rail, the counterweight base, the detection box, the limit plate, the buoyancy mechanism and the roller mechanism. The roller mechanism can accurately detect and calculate the height to which the detection box rises on the surface of the vertical rail, thereby achieving the purpose of accurately calculating the depth of water accumulation inside the mine.

[0016] Secondly, the utility model simplifies the internal structure of the device and reduces the number of electrical components used inside the device through the coordination of vertical rails, counterweight bases, detection boxes, limit plates, buoyancy mechanisms and roller mechanisms, thereby reducing the probability of internal electrical components being damaged due to short circuits. At the same time, damage to a single internal electrical component will not affect the device's detection of the depth of water accumulation inside the mine. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 4 The utility model describes the above technical solution in detail through the following embodiments:

[0025] A mine water accumulation monitoring device comprises: a vertical rail 1; a counterweight base 2 is fixedly connected to the bottom of the vertical rail 1, two detection boxes 3 are sleeved on the outer surface of the vertical rail 1 near the counterweight base 2, and a limit plate 4 for controlling the moving stroke of the detection box 3 is fixedly connected to the top of the vertical rail 1; both sides of the two detection boxes 3 are provided with buoyancy mechanisms 5 for rising and falling according to the water level; the inside of the detection box 3 is provided with a roller mechanism 6 for detecting its moving stroke, and the user places the device at the bottom of the mine. When there is water accumulation inside the mine, the rising water level pushes the buoyancy mechanism 5, and the buoyancy mechanism 5 drives the detection box 3 to rise on the surface of the vertical rail 1. When the detection box 3 rises, the roller mechanism 6 detects the rising stroke of the detection box 3, thereby achieving the purpose of detecting the depth of water accumulation inside the mine.

[0026] like Figure 1 and Figure 2As shown, the buoyancy mechanism 5 includes: connecting rods 7 are fixedly connected to both sides of the two detection boxes 3, and the ends of the connecting rods 7 away from the detection boxes 3 are fixedly connected to the vertical rods 8; the bottom ends of the vertical rods 8 are fixedly connected to the buoyancy balls 9, and when the water level rises, the buoyancy balls 9 will move upward with the water level due to the hollow interior of the buoyancy balls 9, and the buoyancy balls 9 will drive the vertical rods 8 while rising, and the vertical rods 8 will drive the two detection boxes 3 to rise simultaneously on the surface of the vertical rail 1 through the connecting rods 7.

[0027] like Figure 2 As shown, the roller mechanism 6 includes: a first rotating shaft 10 is rotatably connected to one side of the detection box 3, and a first detection wheel 11 is fixedly connected to the outer surface of the first rotating shaft 10 located inside the detection box 3; a second rotating shaft 12 is rotatably connected to the side of the detection box 3 away from the first rotating shaft 10, and a second detection wheel 13 is fixedly connected to the outer surface of the second rotating shaft 12 located inside the detection box 3; one end of the first rotating shaft 10 and the second rotating shaft 12 both penetrate the detection box 3 and extend to the angle sensor 14, and the first rotating shaft 10 and the second rotating shaft 12 are respectively fixedly connected to the detection end of the angle sensor 14, and the angle sensor 14 is fixedly connected to the detection end of the angle sensor 14. The box 3 is fixedly connected, and the detection box 3 drives the first detection wheel 11 and the second detection wheel 13 while rising. Since the first detection wheel 11 and the second detection wheel 13 are in contact with the vertical rail 1, the first detection wheel 11 and the second detection wheel 13 will rotate while rising. The first detection wheel 11 drives the first rotating shaft 10 while rotating, and the second detection wheel 13 drives the second rotating shaft 12 while rotating. Since the first rotating shaft 10 and the second rotating shaft 12 are connected to the detection end of the angle sensor 14, the angle sensor 14 can detect the rotation angle of the first rotating shaft 10 and the second rotating shaft 12.

[0028] like Figure 3 As shown, a controller 15 is fixedly connected to one side of the detection box 3 away from the angle sensor 14. The angle sensors 14 are electrically connected to the controllers 15 respectively. Both controllers 15 are externally connected to a computer. The angle sensor 14 transmits the rotation angles of the first rotating shaft 10 and the second rotating shaft 12 to the inside of the controller 15 respectively. The controller 15 calculates the depth of the accumulated water through the circumference of the first detection wheel 11 and the second detection wheel 13 and the rotation angles of the first rotating shaft 10 and the second rotating shaft 12, and transmits the calculated depth to the inside of the external computer. The computer calculates the average value of the four sets of data to obtain accurate data of the depth of the accumulated water inside the mine.

[0029] like Figure 2As shown, the outer surfaces of the first detection wheel 11 and the second detection wheel 13 are both provided with damping pads 16, and the damping pads 16 are respectively fixedly connected to the first detection wheel 11 and the second detection wheel 13, thereby improving the roughness of the surfaces of the first detection wheel 11 and the second detection wheel 13, thereby improving the friction between the contact surfaces of the first detection wheel 11 and the second detection wheel 13 and the vertical rail 1, avoiding slipping, and further improving the accuracy of the detection data.

[0030] like Figure 2 As shown, rubber pads 17 are provided near the counterweight base 2 near the buoyancy ball 9, and the rubber pads 17 are fixedly connected to the counterweight base 2. The buoyancy ball 9 is generally made of plastic, which can protect the buoyancy ball 9 and prevent the buoyancy ball 9 from breaking when it contacts and collides with the counterweight base 2.

[0031] like Figure 3 As shown, both sides of the vertical rail 1 are fixedly connected with structural plates 18, and the bottom ends of the structural plates 18 are fixedly connected to the counterweight base 2, which improves the stability of the connection between the vertical rail 1 and the counterweight base 2 and avoids breakage at the connection.

[0032] Working principle: As the water level rises, the buoyancy ball 9 moves upward with the water level due to its hollow interior. As the buoyancy ball 9 rises, it drives the vertical rod 8. The vertical rod 8 drives the two detection boxes 3 to rise simultaneously on the surface of the vertical rail 1 through the connecting rod 7. As the detection boxes 3 rise, they drive the first detection wheel 11 and the second detection wheel 13. Since the first detection wheel 11 and the second detection wheel 13 are in contact with the vertical rail 1, the first detection wheel 11 and the second detection wheel 13 will rotate as they rise. The first detection wheel 11 drives the first rotating shaft 10 while rotating, and the second detection wheel 13 drives the second rotating shaft 12 while rotating. The first rotating shaft 10 and the second rotating shaft 12 are connected to the detection end of the angle sensor 14, so the angle sensor 14 can detect the rotation angle of the first rotating shaft 10 and the second rotating shaft 12. The angle sensor 14 transmits the rotation angles of the first rotating shaft 10 and the second rotating shaft 12 to the inside of the controller 15 respectively. The controller 15 calculates the depth of the accumulated water through the circumference of the first detection wheel 11 and the second detection wheel 13 and the rotation angles of the first rotating shaft 10 and the second rotating shaft 12, and transmits the calculated depth to the inside of an external computer. The computer calculates the average value of the four sets of data to obtain accurate data on the depth of water accumulated in the mine.

[0033] Since the two groups of rotation angle sensors 14 and controllers 15 are independently arranged, when one group of rotation angle sensors 14 and controllers 15 is damaged, although the accuracy of the detection data of the water depth inside the mine is reduced, it does not affect the device's detection of the water depth inside the mine.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
