Abstract
Description
Technical Field
[0001] This utility model relates to the field of oxygenation equipment, and in particular to a regulating mechanism and an oxygen production device. Background Technology
[0002] During the construction and operation of underground caverns such as tunnels, mines, and civil defense projects, the working environment is usually a closed or semi-closed structure with extremely poor natural ventilation and restricted airflow, making it difficult for fresh air to enter and oxygen to be replenished in a timely manner. Therefore, the oxygen content in these underground caverns is generally insufficient. To alleviate this situation, workers usually install ventilation and exhaust fans at the entrance to accelerate air circulation and increase the oxygen content in the underground cavern. However, the function of ventilation and exhaust fans is limited to environments that are not completely closed. If the working environment is closed due to an emergency, the oxygen content in the closed underground cavern generally cannot meet the usage requirements. In view of this, we propose a regulating mechanism and an oxygen production device. Utility Model Content
[0003] Therefore, the technical problem to be solved by this utility model is that when an underground cavern is sealed due to an emergency, existing equipment is inconvenient for oxygenation operations to be carried out on the sealed underground cavern.

[0005] As a preferred embodiment of the adjustment mechanism of this utility model, the storage frame is provided with through holes around its perimeter, and a stirring rod is rotatably installed in the working cavity, with a stirring paddle on the stirring rod.
[0006] In a preferred embodiment of the adjustment mechanism of this utility model, the driving component includes a driving motor mounted on the housing, a winding disc coaxially fixed to the output end of the driving motor, and the winding disc coaxially fixed to the stirring paddle, and a traction rope with one end fixed to the storage frame is wound around the outside of the winding disc.
[0007] As a preferred embodiment of the adjustment mechanism of this utility model, the winding disc has a winding cavity for storing the traction rope, and a limiting cavity is provided on the side of the winding cavity near the center of the winding disc, and the limiting cavity and the winding cavity are interconnected.
[0008] As a preferred embodiment of the adjustment mechanism of this utility model, a sliding ring is provided at the connection between the limiting cavity and the winding cavity, which is slidably connected to both the limiting cavity and the winding cavity. The outer arc surface of the sliding ring is fixedly connected to the traction rope, and the inner arc surface is provided with a limiting member for restricting the sliding of the sliding ring.
[0009] As a preferred embodiment of the adjustment mechanism of this utility model, the limiting member includes a limiting insertion hole opened on the inner arc surface of the sliding ring, a limiting rod slidably installed in the limiting insertion hole, a limiting arc block fixed coaxially with the winding disc in the limiting cavity, a limiting spring abutting against the inner wall of the limiting insertion hole at one end of the limiting rod, and the other end contacting the limiting arc block.
[0010] As a preferred embodiment of the adjustment mechanism of this utility model, the limiting arc block includes an adjustment surface for adjusting the insertion depth of the limiting rod in the limiting hole and an abutting surface that abuts against the limiting rod.
[0011] As a preferred embodiment of the adjustment mechanism of this utility model, a friction-reducing rotating cylinder that contacts the sliding ring is provided in the limiting cavity and near the winding cavity.
[0012] The beneficial effects of the adjustment mechanism of this utility model are as follows: by continuously generating oxygen through chemical reagents in the working chamber, the oxygen concentration in the underground cavern is increased, meeting the normal needs of the staff. Furthermore, by utilizing the setting of the adjustment components, the chemical reagents in the working chamber can increase the oxygen generation efficiency in the closed state of the underground cavern, alleviating the oxygen deficiency in the closed underground cavern.

[0026] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0027] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.
[0028] This embodiment provides an adjustment mechanism, such as Figure 1 and Figure 2 As shown, the housing 1 contains a working chamber 2 for storing hydrogen peroxide. Since hydrogen peroxide decomposes to produce oxygen, this oxygen escapes from the working chamber 2 into the underground cavern, increasing the oxygen concentration and preventing oxygen deficiency for workers. Figure 2 As shown, a storage frame 31 is suspended in the working chamber 2 and is located above the hydrogen peroxide liquid surface. Solid manganese dioxide is placed in the storage frame 31. The manganese dioxide can act as a catalyst for hydrogen peroxide to accelerate the production of oxygen. In addition, an oxygen content detection sensor connected to the drive assembly 4 is also provided on the housing 1. When the oxygen concentration in the underground cavern drops to the set value, the drive assembly 4 will control the storage frame 31 to descend, so that the hydrogen peroxide in the working chamber 2 passes through the through hole 32 provided on the storage frame 31 and fully contacts the manganese dioxide inside the storage frame 31, thereby accelerating the decomposition of hydrogen peroxide, accelerating the oxygen replenishment efficiency in the underground cavern, alleviating the oxygen deficiency in the closed underground cavern, and thus solving the problem that existing equipment is not easy to increase the oxygen concentration in the underground cavern under closed conditions.
[0029] like Figure 2 As shown, a stirring rod 33 is rotatably installed in the working chamber 2, and a stirring paddle 34 is provided on the stirring rod 33. When the drive assembly 4 descends in the air storage frame 31, it can also drive the stirring rod 33 to rotate and control the stirring paddle 34 to stir the hydrogen peroxide in the working chamber 2, so that the concentration of each part of the hydrogen peroxide tends to be uniform, and avoids the oxygen generation reaction from slowing down due to "local depletion". At the same time, the fluctuating hydrogen peroxide will also impact the manganese dioxide solid in the storage frame 31, so that it will not stay in one position, increasing the effective contact area between the manganese dioxide solid and the hydrogen peroxide, and improving the oxygen generation efficiency of the hydrogen peroxide.
[0030] like Figure 2 As shown, a drive motor 41 is fixedly installed on the housing 1. A winding disc 42 is coaxially fixed to the output end of the drive motor 41, and a winding cavity 44 is opened on the winding disc 42. A traction rope 43, one end of which is fixedly connected to the storage frame 31, is wound in the winding cavity 44. Figure 5As shown, a limiting cavity 45 communicating with the winding cavity 44 is provided on the side of the winding cavity 44 near the center of the winding disc 42, and a sliding ring 46 fixed to the traction rope 43 is slidably installed at the communication between the winding cavity 44 and the limiting cavity 45. Figure 3 As shown, the limiting cavity 45 is also provided with a limiting member 48 for limiting the movement of the sliding ring 46.
[0031] Therefore, when the storage frame 31 is suspended, the traction rope 43 is wound and stored in the winding cavity 44. If it is necessary to accelerate the hydrogen peroxide reaction, the winding disc 42 can be rotated via the drive motor 41 to release the traction rope 43, causing the storage frame 31 to fall into the hydrogen peroxide until all the traction rope 43 in the winding cavity 44 is released. At this point, if the winding disc 42 is continued to rotate, the sliding ring 46 will slide on the winding disc 42 and will not wrap around the traction rope 43. Furthermore, if... Figure 2 As shown, the stirring rod 33 is coaxially fixed with the winding disc 42. Therefore, when the winding disc 42 rotates, it will drive the stirring paddle 34 to rotate through the stirring rod 33, thereby accelerating the decomposition of hydrogen peroxide.
[0032] When there is no need to accelerate oxygen generation efficiency, the winding disc 42 can be reversed by driving motor 41. At this time, the sliding ring 46 will stop sliding on the winding disc 42 under the action of the limiting member 48, and instead move together with the winding disc 42. Therefore, the traction rope 43 will be wound in the winding cavity 44 to lift the storage frame 31 until the storage frame 31 is lifted to the set height, at which point the driving motor 41 will stop.
[0033] like Figure 6 As shown, a friction-reducing rotating cylinder 47 is rotatably installed in the limiting cavity 45, which contacts the sliding ring 46. The setting of the friction-reducing rotating cylinder 47 converts the sliding friction between the sliding ring 46 and the limiting cavity 45 into rolling friction, thereby reducing the coefficient of friction and reducing the frictional loss of components such as the sliding ring 46 and the inner wall of the limiting cavity 45, thereby improving the service life of the relevant components.
[0034] like Figure 4 As shown, the limiting cavity 45 is provided with a limiting arc block 483 that is coaxially fixed with the winding disc 42. The inner arc surface of the sliding ring 46 is provided with a limiting insertion hole 481. A limiting insertion rod 482 is slidably installed in the limiting insertion hole 481. One end of the limiting insertion rod 482 is fixedly installed with a limiting spring 484 that abuts against the inner wall of the limiting insertion hole 481, and the other end is in contact with the limiting arc block 483.
[0035] Therefore, under the action of the limiting spring 484, the limiting rod 482 remains in contact with the limiting slider. Furthermore, as... Figure 4As shown, the limiting arc block 483 is provided with an adjustment surface 4831 in a raised state and an abutment surface 4832 at the highest point of the limiting arc block 483. Therefore, when the storage frame 31 descends, the limiting rod 482 contacts the adjustment surface 4831 and moves from the lowest point to the highest point of the limiting arc block 483. This process repeats without obstructing the movement of the sliding ring 46. When the storage frame 31 rises, the limiting rod 482 moves from the highest point to the lowest point of the limiting arc block 483 and abuts against the abutment surface 4832 on the limiting arc block 483, causing the sliding ring 46 to rotate with the winding disc 42, thereby winding the traction rope 43. In addition, because the limiting spring 484 abuts against the inner wall of the limiting hole 481, it is convenient for the staff to replace the limiting spring 484 in a timely manner after the elastic potential energy decreases.
[0036] This embodiment also provides an oxygen production apparatus, such as... Figure 7 As shown, the housing 1 is also provided with a purification chamber 5 that is connected to the working chamber 2. The purification chamber 5 contains clean water, and a connecting pipe 6 is provided at the connection between the purification chamber 5 and the working chamber 2. One end of the connecting pipe 6 extends into the clean water.
[0037] This design of the connecting pipe 6 allows the oxygen generated in the working chamber 2 to be directly introduced into the clean water. Since oxygen is insoluble in water, the clean water can filter out some impurities in the working chamber 2 that enter the purification chamber 5 along with the oxygen, so that pure oxygen can be discharged from the housing 1 through the air outlet 7.
[0038] like Figure 8 As shown, a rotating blade 8 is rotatably installed at the vent 7, and an indicator dial 9 is installed on the outside of the housing 1. An indicator needle 10, which is rotatably connected to the rotating blade 8, is rotatably installed in the indicator dial 9. Because the oxygen generation efficiency of hydrogen peroxide is related to its own concentration, after hydrogen peroxide continuously generates oxygen, the concentration of hydrogen peroxide will decrease, which will further reduce the oxygen generation efficiency of hydrogen peroxide. Therefore, when oxygen is discharged from the housing 1 through the vent 7, it will drive the indicator needle 10 to rotate through the rotating blade 8. The staff can periodically observe the rotation rate of the indicator needle 10 to determine the hydrogen peroxide content in the working chamber 2, so as to replace the hydrogen peroxide in time through the liquid inlet pipe 11 and the liquid outlet pipe 12 on the housing 1 that connect to the working chamber 2, and ensure the oxygen concentration in the underground cavern.
[0039] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
