DETAILED DESCRIPTION

[0034] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0035] The utility model provides the following preferred embodiments:

[0036] Embodiment 1, as Figure 1-Figure 7As shown, the intelligent monitoring type environmental protection gas cabinet includes a gas cabinet body 11, an infrared gas sensor 12, a trigger mechanism and an extraction mechanism. The infrared gas sensor 12 is installed on the top of the inner cavity of the gas cabinet body 11. The infrared gas sensor 12 is a gas sensing device that uses the relationship between gas concentration and absorption intensity to identify gas components and determine their concentrations based on the near-infrared spectrum selective absorption characteristics of different gas molecules. The infrared gas sensor 12 is a prior art and will not be specifically described here. In actual use, the infrared gas sensor 12 is electrically connected to the controller. When the infrared gas sensor 12 detects that a gas leak occurs in the gas cabinet body 11, it will send a signal to the controller;

[0037] The trigger mechanism includes a control box 24, a lifting plate 26, a position sensor 28 and a push assembly. The control box 24 is installed at the top of the gas cabinet body 11, and the fan blade 16 is slidably arranged inside the control box 24. The position sensor 28 is located at the bottom end of the lifting plate 26 and is installed on the inner wall of the control box 24. The position sensor 28 is electrically connected to the controller. The position sensor 28 can sense the position of the object to be measured and convert it into a sensor that can be used for output signals. The position sensor 28 is a prior art and will not be specifically described here. The push assembly is installed between the lifting plate 26 and the control box 24;

[0038] The push assembly can drive the lifting plate 26 to move. When the infrared gas sensor 12 detects gas leakage inside the gas cabinet body 11, the controller can drive the push assembly to work, so that the push assembly can drive the lifting plate 26 to move downward. When the position sensor 28 detects that the distance between the lifting plate 26 and the position sensor 28 reaches the set distance, a signal is sent to the controller, and the controller controls the solenoid valve on the gas cylinder to close, so as to prevent the gas from continuing to be transported to the inside of the gas cabinet body 11.

[0039] The extraction mechanism includes a collection box 21, a vertical shaft 19, a conveying assembly, a first transmission assembly, a rotating assembly, three annular covers 13, a plurality of blades 16 and three second transmission assemblies. The three annular covers 13 are equidistantly installed on one side of the gas cabinet body 11, each annular cover 13 is connected to the gas cabinet body 11, and each three blades 16 are located inside an annular cover 13. The vertical shaft 19 passes through the three annular covers 13 and is rotatably connected to the three annular covers 13. Each second transmission assembly is installed inside an annular cover 13, and each second transmission assembly is located between the vertical shaft 19 and the three blades 16. The second transmission assembly can realize the connection between the vertical shaft 19 and the blades 16. When the vertical shaft 19 rotates, it can drive the blades 16 to rotate.

[0040] The collecting box 21 is installed at the rear side of the gas cabinet body 11. The collecting box 21 is used to store leaked gas. The conveying assembly is located between the collecting box 21 and the three annular covers 13. The conveying assembly can convey gas to the inside of the collecting box 21. The rotating assembly is installed at the top of the vertical shaft 19. The first transmission assembly is located between the rotating assembly and the lifting plate 26.

[0041] When a gas leak is detected, the controller drives the lifting plate 26 to move downward. When the lifting plate 26 moves, on the one hand, it can drive the solenoid valve on the gas cylinder to close through the position sensor 28 and the controller, and on the other hand, it can drive the vertical shaft 19 to rotate through the second transmission assembly and the rotating assembly. Then, through the three second transmission assemblies, the fan blades 16 inside each annular cover 13 can be rotated, thereby realizing the extraction of gas inside the gas cabinet body 11, and the leaked toxic gas can be transported to the inside of the collection box 21 through the conveying assembly for storage.

[0042] like Figure 1-Figure 7 As shown, the conveying assembly includes a main pipe 22 and three branch pipes 20. One end of each annular cover 13 away from the gas cabinet body 11 is equipped with a branch pipe 20. The other end of each branch pipe 20 is connected to the same main pipe 22. One end of the main pipe 22 is connected to the collection box 21.

[0043] When the fan blades 16 rotate, the gas inside the gas cabinet body 11 can be drawn into the annular cover 13, and the gas can be transported to the inside of the collection box 21 for storage through the branch pipe 20 and the main pipe 22, thereby preventing the gas from continuing to leak out and causing personal injury and environmental pollution.

[0044] like Figure 1-Figure 7 As shown, each branch pipe 20 is installed with a one-way valve 23, which can control the one-way flow of gas, so that the gas can only move toward the direction close to the collection box 21, avoiding the gas from flowing out in the opposite direction.

[0045] like Figure 1-Figure 7 As shown, each second transmission assembly includes a first bevel gear 17 and a second bevel gear 18, a central shaft 15 is rotatably provided inside the annular housing 13, three blades 16 located inside the annular housing 13 are equidistantly fixed on the surface of the central shaft 15, the first bevel gear 17 is fixedly mounted on the end of the central shaft 15, the second bevel gear 18 is fixed on the surface of the vertical shaft 19, and the first bevel gear 17 and the second bevel gear 18 are meshed with each other;

[0046] When the rotating assembly is working, it can drive the vertical shaft 19 to rotate, and the vertical shaft 19 can drive the second bevel gear 18 to rotate. Since the second bevel gear 18 and the first bevel gear 17 are meshed with each other, when the second bevel gear 18 rotates, it can drive the first bevel gear 17 to rotate, so that the central shaft 15 can drive the three fan blades 16 to rotate, thereby realizing the extraction of gas.

[0047] like Figure 1-Figure 7 As shown, a mounting frame 14 is fixed inside the annular cover 13, and one end of the central axis 15 is rotatably set on the mounting frame 14 through a bearing to support the central axis 15. A through hole is formed between the annular cover 13 and the mounting frame 14 to facilitate the passage of gas, so that the gas can flow from the gas cabinet body 11 to the inside of the annular cover 13.

[0048] like Figure 1-Figure 7 As shown, the first transmission assembly includes a first toggle rod 29, a swing rod 30, a first strip groove 31, a second strip groove 32, a second toggle rod 33 and a rack 34;

[0049] The swing rod 30 is rotatably arranged inside the mounting frame 14 through the rotating rod. The first strip groove 31 and the second strip groove 32 are both opened on the surface of the mounting frame 14 and are located on both sides of the rotating rod. Specifically, the length of the first strip groove 31 is smaller than the length of the second strip groove 32. The first toggle rod 29 is inserted into the inside of the first strip groove 31. One end of the first toggle rod 29 is fixedly connected to the lifting plate 26. When the lifting plate 26 moves downward, it can drive the first toggle rod 29 to move downward. Since the first toggle rod 29 is inserted into the inside of the first strip groove 31, when the first toggle rod 29 moves downward, it can drive the swing rod 30 to rotate around the axis of the rotating rod connected thereto. The rack 34 is slidably arranged on one side of the gas cabinet body 11. The second toggle rod 33 is inserted into the inside of the second strip groove 32. One end of the second toggle rod 33 is fixedly connected to the surface of the rack 34. When the swing rod 30 rotates, the rack 34 can be driven to move upward through the second toggle rod 33.

[0050] like Figure 1-Figure 7 As shown, a guide rail 36 is fixed to one side of the gas cabinet body 11, and the rack 34 is slidably set on the guide rail 36. The guide rail 36 is used to guide and limit the rack 34 to ensure the stability of the rack 34 when moving.

[0051] like Figure 1-Figure 7As shown, the rotating assembly includes a gear 35, a driving wheel 38, a driven wheel 39, a transmission belt 40, a third bevel gear 42 and a fourth bevel gear 43. A first mounting plate 37 is fixed to one side of the guide rail 36. The gear 35 is rotatably arranged on the first mounting plate 37 to support the gear 35. The gear 35 is meshed with the rack 34. When the rack 34 moves upward under the action of the rotation of the swing rod 30, the gear 35 can be driven to rotate. The driving wheel 38 is located on one side of the first mounting plate 37 and is coaxially arranged with the gear 35. When the gear 35 rotates, the driving wheel 38 can be driven to rotate synchronously. A second mounting plate 41 is fixedly installed on one side of the gas cabinet body 11. The driven wheel 39 is rotatably arranged on the second mounting plate 41. The transmission belt 40 is sleeved on the surfaces of the driven wheel 39 and the driving wheel 38. When the driving wheel 38 rotates, the driven wheel 39 can be driven to rotate by the transmission belt 40.

[0052] The third bevel gear 42 is located at one side of the second mounting plate 41 and is coaxially arranged with the driven wheel 39. When the driven wheel 39 rotates, it can drive the third bevel gear 42 to rotate synchronously. The fourth bevel gear 43 is installed at the top of the vertical shaft 19. The fourth bevel gear 43 and the third bevel gear 42 are meshed. When the third bevel gear 42 rotates with the rotation of the driven wheel 39, since the third bevel gear 42 and the fourth bevel gear 43 are meshed with each other, when the third bevel gear 42 rotates, the fourth bevel gear 43 can be driven to rotate, and then the vertical shaft 19 can be driven to rotate.

[0053] When the rack 34 moves upward, it can drive the gear 35 to rotate, and the gear 35 can drive the driving wheel 38 coaxially arranged therewith to rotate. Under the action of the transmission belt 40, when the driving wheel 38 rotates, it can drive the driven wheel 39 to rotate, and the driven wheel 39 can drive the third bevel gear 42 coaxially arranged therewith to rotate. Since the third bevel gear 42 and the fourth bevel gear 43 are meshed, when the third bevel gear 42 rotates, it can drive the fourth bevel gear 43 to rotate, so that the vertical shaft 19 can be rotated, so as to drive the three second transmission components to work.

[0054] like Figure 1-Figure 7 As shown, the diameter of the driving wheel 38 is greater than the diameter of the driven wheel 39, and the diameter of the third bevel gear 42 is greater than the diameter of the fourth bevel gear 43, which is used to increase the speed so that the fan blades 16 can rotate at high speed.

[0055] like Figure 1-Figure 7As shown, the pushing assembly includes a cylinder 25 and two guide rods 27. The cylinder 25 is fixedly mounted on the mounting frame 14. The output end of the cylinder 25 is fixedly connected to the top of the lifting plate 26. The two guide rods 27 are fixed inside the gas cabinet body 11. Each guide rod 27 is arranged through the lifting plate 26. The lifting plate 26 and the guide rods 27 are slidably connected. When the cylinder 25 is working, it can drive the lifting plate 26 to move downward. At the same time, the two guide rods 27 can play a guiding and limiting role to ensure the stability of the lifting plate 26 when it moves downward.
