Description

Technical Field

[0001] This utility model relates to the field of tunnel floor heave technology, and in particular to a control and management device for tunnel floor heave. Background Technology

[0002] Tunnel floor bulging refers to the phenomenon where the rock strata at the bottom of a mine or tunnel bulge upwards due to the expansion of the rock strata when exposed to water. It usually occurs during tunnel excavation or in humid environments in mines, where the rock strata contain expansive minerals such as montmorillonite. When exposed to water, the minerals absorb water and their volume increases, causing the rock strata to expand, deform, and bulge into the tunnel.

[0003] The phenomenon of roadway floor heave reduces the effective height of the roadway, affects the operating efficiency of the ventilation system, and may even cause local airflow obstruction, thereby affecting the safety of workers. This is especially true in enclosed mines or tunnels, where special attention and monitoring are required to prevent air quality deterioration.

[0004] One method for controlling and managing the floor heave phenomenon in roadways is to dehumidify the roadway to control the humidity level. The dehumidification method commonly used in roadways is dry air dehumidification, which involves injecting dry air into the floor heave and using airflow to expel water vapor. This method requires good air circulation in the roadway, which limits the practical use of dehumidification equipment using dry air dehumidification and results in less than ideal dehumidification effects. Utility Model Content

[0005] The main purpose of this utility model is to provide a control and treatment device for roadway floor damping, which can effectively solve the problem that equipment for injecting dry air into the roadway floor damping to dehumidify the roadway requires high air flow in the roadway, resulting in an unsatisfactory dehumidification effect.

The left output end of the motor is fixedly connected to a rotating rod two via a coupling. A fan blade one is fixedly connected to the outer surface of the rotating rod two.

[0010] Preferably, the ventilation assembly includes a driven assembly, and a driving assembly is disposed on the right side of the driven assembly.

[0011] Preferably, the drive assembly includes a bevel gear, a round rod is rotatably connected to the middle of the right end of the ventilation pipe and extends into the ventilation pipe, a pulley set is fixedly connected to the right side of the outer surface of the round rod and the outer surface of the rotating rod, and the bevel gear is fixedly connected to the left side of the outer surface of the round rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The drying component of this utility model can continuously inject dry air into the bulging area of ​​the tunnel floor, accelerate the evaporation of water vapor at the bulging area, and help dehumidify the tunnel, thereby treating and controlling the bulging phenomenon. The ventilation component accelerates the air circulation speed in the tunnel, draws water vapor into the ventilation pipe, and then discharges it through the connecting pipe, thereby effectively reducing the humidity in the tunnel and effectively treating and controlling the bulging phenomenon caused by the expansion of the tunnel floor when exposed to water.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example 1

[0025] like Figure 1 and Figure 2 As shown, a control and treatment device for roadway floor heave includes a fixed plate 1, a drying component 2 is provided at the upper middle part of the fixed plate 1, a ventilation pipe 3 is fixedly connected to the upper side of the drying component 2, an air inlet shell 4 is fixedly connected to the left end of the ventilation pipe 3, an installation plate 5 is fixedly connected to the inner surface of the air inlet shell 4, a ventilation component 6 is provided at the upper middle part of the installation plate 5, a number of fan components 7 are arranged in an arc-shaped array at the upper end of the installation plate 5, and a through connecting pipe 8 is fixedly connected to the upper right part of the ventilation pipe 3.

[0026] In practice, the drying component 2 is connected to the air inlet pipe in the tunnel, and the connecting pipe 8 is connected to the air outlet pipe in the tunnel.

[0027] Turn on the drying component 2 to draw in air from the outside environment, dehumidify and dry the air, and then continuously inject dry air into the bottom drum of the tunnel. The dry air injected into the bottom drum of the tunnel will accelerate the evaporation of water vapor in the tunnel.

[0028] After injecting dry air into the tunnel for a period of time, so that the tunnel is filled with a certain amount of water vapor, stop injecting dry air into the tunnel floor drum, turn on the drying component 2 to drive the ventilation component 6 to operate, draw the water vapor in the tunnel into the air inlet shell 4, and then discharge it to the outside of the tunnel through the ventilation pipe 3 and the connecting pipe 8.

[0029] The operation of ventilation component 6 drives the operation of several fan components 7, thereby improving the efficiency of extracting water vapor in the roadway.

[0030] After the water vapor in the tunnel is extracted to a certain extent, the drying component 2 stops driving the ventilation component 6. The drying component 2 is turned on to continue injecting dry air into the tunnel floor, so that the water in the tunnel floor continues to evaporate.

[0031] In this way, the drying component 2 injects dry air into the bottom drum of the tunnel to accelerate the evaporation of water in the tunnel, and the ventilation component 6 is turned on to extract the water vapor generated by the evaporation of water out of the tunnel. The drying component 2 and the ventilation component 6 work alternately to dehumidify the tunnel.

[0032] Example 2

[0033] Specifically, in order to dehumidify the tunnel and thus effectively control and treat tunnel floor heave, please refer to... Figure 3The drying assembly 2 includes an air storage box 21, which is fixedly connected to the upper middle part of the fixed plate 1. A ventilation pipe 3 is fixedly connected to the upper middle part of the air storage box 21. Drying plates 22 are fixedly connected to both the front and rear ends of the air storage box 21. A through connecting pipe 23 is fixedly connected to the front right end of the air storage box 21. A second drying plate 24 is fixedly connected to the outer surface of the connecting pipe 23. A dehumidification assembly 25 is installed in the middle right side of the inner surface of the air storage box 21. A third dehumidification assembly 25 is fixedly connected to the middle left end of the air storage box 21. The air outlet duct 26 is through the air supply; the dehumidification assembly 25 includes a motor 251, which is fixedly connected to the middle right side of the inner surface of the air storage box 21. The right output end of the motor 251 is fixedly connected to a rotating rod 252 via a coupling. The right end of the rotating rod 252 passes through the right side of the inner surface of the air storage box 21 and extends to the outside of the air storage box 21. The left output end of the motor 251 is fixedly connected to a rotating rod 253 via a coupling. A fan blade 254 is fixedly connected to the outer surface of the rotating rod 253.

[0034] The two drying plates 22 and 24 mentioned above are both mature technologies in the prior art. This solution only borrows their functions of converting electrical energy into cold energy and setting the heating temperature. Their structure and working principle will not be elaborated further here.

[0035] The motor 251 mentioned above is a dual-axis motor, which is a mature technology in the existing technology. This solution only borrows its function of having two axes and the ability of the two axes to control the object to run independently or simultaneously. Its structure and working principle will not be elaborated further.

[0036] In the specific implementation, the connecting pipe 23 is connected to the air inlet pipe of the roadway, the connecting pipe 8 is connected to the air outlet pipe of the roadway, and both drying plates 1 22 and drying plate 24 are powered on and set with appropriate drying humidity.

[0037] When the motor 251 is turned on, the rotating rod 253 rotates, which in turn drives the fan blade 254 to rotate. The rotation of the fan blade 254 draws air from the external environment into the air storage box 21 through the connecting pipe 23. The drying plate 24 and the two drying plates 22 will dry the air, thus drying the air.

[0038] When the fan blade 254 rotates, it blows the dry air in the air storage box 21 into the air outlet pipe 26, and then blows it out through the air outlet pipe 26 into the bottom drum of the roadway. After the high temperature and dry air enters the bottom drum of the roadway, it can accelerate the evaporation of water at the bottom drum of the roadway, thereby helping to dehumidify the roadway and thus treat and control the bottom drum phenomenon of the roadway.

[0039] The second drying plate 24 can pre-dry the cold air entering the connecting pipe 23. After the pre-dried air enters the air storage box 21, it will be further heated by the two drying plates 22, thereby improving the efficiency of heating the air into dry air and improving the airflow into the air storage box 21. This improves the overall operating efficiency of the drying assembly 2, thereby improving the efficiency of the drying assembly 2 in treating water vapor at the bottom of the roadway.

[0040] Example 3

[0041] Specifically, in order to accelerate air circulation within the tunnel after injecting dry air at the tunnel floor, thereby speeding up the removal of water vapor, refer to... Figure 4 The ventilation assembly 6 includes a driven assembly 62, and a drive assembly 61 is provided on the right side of the driven assembly 62. The drive assembly 61 includes a bevel gear 613. A round rod 612 is rotatably connected to the middle of the right end of the ventilation pipe 3 and extends into the ventilation pipe 3. A pulley group 611 is fixedly connected to the right side of the outer surface of the round rod 612 and the outer surface of the rotating rod 252. The bevel gear 613 is fixedly connected to the left side of the outer surface of the round rod 612.

[0042] Further reading Figure 5 The driven component 62 includes a first rotating shaft 623, which is rotatably connected to the middle of the upper end of the mounting plate 5. A second bevel gear 622 is fixedly connected to the middle of the outer surface of the first rotating shaft 623, and the second bevel gear 622 meshes with the first bevel gear 613. A drive gear 621 is fixedly connected to the lower side of the outer surface of the first rotating shaft 623, and a second fan blade 624 is fixedly connected to the upper side of the outer surface of the first rotating shaft 623. The fan assembly 7 includes a second rotating shaft 72, which is rotatably connected to the left side of the upper end of the mounting plate 5. A third fan blade 71 is fixedly connected to the upper side of the outer surface of the second rotating shaft 72, and a driven gear 73 is fixedly connected to the lower side of the outer surface of the second rotating shaft 72, and the driven gear 73 meshes with the drive gear 621.

[0043] In practice, after the drying component 2 is turned on and dry air is continuously injected into the bottom drum of the tunnel for a period of time, the water in the tunnel will evaporate and generate a large amount of water vapor.

[0044] When the two drying plates 22 and 24 are closed, the motor 251 stops rotating the rotating rod 253 and instead drives the rotating rod 252 to rotate.

[0045] Under the action of the pulley assembly 611, the rotation of the first rotating rod 252 drives the round rod 612 to rotate, which in turn drives the first bevel gear 613 to rotate, which in turn drives the second bevel gear 622 to rotate, which in turn drives the first rotating shaft 623 to rotate, which in turn drives the second fan blade 624 to rotate.

[0046] The water vapor generated by the evaporation of moisture in the tunnel rises upwards. The rotating fan blade 624 draws the water vapor into the air inlet shell 4, and then discharges it from the tunnel outlet through the ventilation pipe 3 and the connecting pipe 8, thereby effectively reducing the humidity in the tunnel and effectively treating and controlling the tunnel floor heave phenomenon.

[0047] The rotation of shaft 623 drives the drive gear 621 to rotate, which in turn drives several driven gears 73 to rotate, which in turn drives several shafts 72 to rotate, which in turn drives several fan blades 71 to rotate.

[0048] With both fan blade 2 624 and several fan blades 3 71 rotating, the efficiency of drawing water vapor from the tunnel into the air inlet casing 4 and then expelling it through the tunnel exhaust port can be greatly improved, while also accelerating the air circulation speed in the tunnel.

[0049] After the ventilation component 6 is turned on to release a certain amount of water vapor in the tunnel, the motor 251 stops driving the first rotating rod 252 to rotate, and instead drives the second rotating rod 253 to rotate, turning on the drying component 2, so that the drying component 2 continues to release dry air to the bottom of the tunnel.

[0050] In this way, the alternating use of the drying component 2, the ventilation component 6, and several fan components 7 dehumidifies the roadway, thereby effectively controlling the roadway floor heave phenomenon.

[0051] It should be noted that the specific installation methods, circuit connection methods, and control methods of the two drying plates 22, the second drying plate 24, and the motor 251 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0052] The working principle of this utility model is as follows:

[0053] Connect the connecting pipe 23 to the air inlet pipe of the roadway, and connect the connecting pipe 8 to the air outlet pipe of the roadway.

[0054] Power on both drying plates 1 22 and drying plate 24 and set appropriate humidity. Turn on motor 251 to drive rotating rod 253 to rotate, thereby driving fan blade 1 254 to rotate, drawing air from the external environment into the air storage box 21 through connecting pipe 23.

[0055] Both the second drying plate 24 and the two drying plates 22 pre-dry the air by heating it into dry air. The fan blade 254 rotates to blow the dry air into the tunnel floor drum, accelerating the evaporation of water at the tunnel floor drum.

[0056] After continuously injecting dry air into the tunnel floor drum for a period of time by turning on the drying component 2, close the two drying plates 1 22 and 24, and adjust the motor 251 to no longer drive the rotating rod 253 to rotate, but instead drive the rotating rod 1 252 to rotate.

[0057] Rotating rod 252 causes the round rod 612 to rotate, which in turn causes the rotating shaft 623 to rotate, thereby driving the fan blade 624 to rotate. The rotation of the rotating shaft 623 drives the drive gear 621 to rotate, which in turn drives several driven gears 73 to rotate, thereby causing several fan blades 71 to rotate.

[0058] Fan blade 2 624 and several fan blades 3 71 all rotate, drawing water vapor generated by water evaporation in the tunnel into the air inlet casing 4, and then discharging it out of the tunnel through the ventilation pipe 3 and connecting pipe 8 from the tunnel outlet.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
