DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1 In this embodiment, an escape device for pressurized working equipment includes a workbench 1, an escape pipe 2 is fixed on the right side of the upper surface of the workbench 1, a bracket 3 is fixed on the outer side of the escape pipe 2, the bracket 3 supports the escape pipe 2, a fixing plate 4 is fixed on the left side of the escape pipe 2, and an escape mechanism 5 for closing the passage after escape is arranged on the fixing plate 4 to prevent the shock wave generated by the accident during the escape of the staff from causing harm to the staff, and a guiding mechanism 6 for guiding the escape of the staff is arranged on the escape pipe 2, so that the staff can escape from the scene as quickly as possible and grasp the best escape time.

[0023] There are two brackets 3, which are symmetrically distributed front and back about the central axis of the escape duct 2, so that the escape duct 2 always maintains stability.

[0024] See also Figure 2-3 In order to prevent the shock wave generated by the accident during the escape of the staff from causing harm to the staff, the escape mechanism 5 in this embodiment includes a connecting hole 501 opened on the left side of the fixed plate 4, a mounting block 502 is fixed on the inner side of the connecting hole 501, a connecting rod 503 is fixed inside the mounting block 502, a baffle 504 is arranged inside the connecting hole 501, a connecting groove 505 is arranged on the outer side of the baffle 504, two ends of the connecting rod 503 are respectively rotatably connected to the front and rear inner walls of the connecting groove 505 through bearings, so that the baffle 504 can be turned around the connecting rod 503 as the center, and the front and rear sides of the mounting block 502 are respectively fixed to the front and rear inner walls of the connecting groove 505. The torsion spring 506 is stretched and stores elastic potential energy. After the staff escapes from the escape pipe 2, the baffle 504 loses the effect of external force, and the torsion spring 506 rebounds the baffle 504 to the initial position so as to close the escape pipe 2. An unlocking component is arranged on the fixed plate 4.

[0025] In this example, the inner diameter of the communication hole 501 matches the inner diameter of the escape pipe 2 , and the outer diameter of the baffle 504 matches the inner diameter of the communication hole 501 , so that the staff can enter the escape pipe 2 after opening the baffle 504 .

[0026] It should be noted that the unlocking component includes a touch switch 507, which is fixed to the left side of the fixing plate 4, a limit plate 508 is fixed to the inner side of the connecting hole 501, an electromagnet 509 is fixed to the right side of the limit plate 508, and an iron sheet 510 is fixed to the left side of the baffle 504. After the touch switch 507 is touched, the electromagnet 509 is temporarily powered off and loses its magnetism. At this time, the iron sheet 510 on the baffle 504 is no longer adsorbed, and the baffle 504 can be pushed to open the escape pipe 2, so that the staff can enter the escape pipe 2. When the emergency escape duct 2 is in an emergency, the torsion spring 506 rebounds the baffle 504 to its initial position, and then the electromagnet 509 is restored to be connected and generates magnetism, which adsorbs the iron sheet 510 on the baffle 504, and closes the escape duct 2 again, thereby blocking the shock wave generated in the accident. There are two limit plates 508, which are symmetrically distributed front and back with the central axis of the connecting hole 501. The number of iron sheets 510 is equal to the number of electromagnets 509, and their positions correspond one to one, thereby improving the adsorption force when adsorbing the iron sheet 510, so that the baffle 504 can withstand a stronger impact.

[0027] See also Figure 4In order to enable the staff to escape from the scene at the fastest speed and grasp the best escape time, the guiding mechanism 6 in this embodiment includes two connecting blocks 601, both of which are fixed to the inner side of the escape pipe 2, and a guide rod 602 is fixed between the opposite sides of the two connecting blocks 601, and a slider 603 is slidably connected to the outer side of the guide rod 602, and a grab ring 604 is hinged on the lower surface of the slider 603 through a hinge shaft. Before the staff enters the escape pipe 2 to escape, they need to grab the grab ring 604. The grab ring 604 can guide the escape trajectory under the cooperation of the slider 603 and the guide rod 602. At the same time, the grab ring 604 can keep the staff's body stable, avoid flipping inside the escape pipe 2, causing themselves to lose their sense of direction and lose the best escape time. An anti-slip pad 605 is fixed on the outer side of the grab ring 604 to increase the friction between the grab ring 604 and the palm of the staff, so that the grab ring 604 can be grasped more firmly.

[0028] In this example, a pad 606 is fixed to the right side of the escape pipe 2, and a sponge pad 607 is fixed to the upper surface of the pad 606. After escaping from the escape pipe 2, the sponge pad 607 cushions the staff to avoid falling injuries.

[0029] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.

[0030] The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0031] The working principle of the above embodiment is:

[0032] (1) A worker works on a workbench 1 of a pressurized working equipment. When an accident occurs in the pressurized working equipment, the worker quickly moves to the escape pipe 2, touches the touch switch 507 with one hand, and pushes the baffle 504 with the other hand. After the touch switch 507 is touched, the electromagnet 509 is temporarily powered off and loses its magnetism. At this time, the iron sheet 510 on the baffle 504 is no longer adsorbed, and the baffle 504 can be pushed. The baffle 504 flips around the connecting rod 503, so that the escape pipe 2 is opened, and the worker can enter the escape pipe 2 to escape.

[0033] (2) In the process of opening the escape duct 2, the torsion spring 506 is stretched and stores elastic potential energy. After the staff escapes from the escape duct 2, the baffle 504 loses the effect of external force, and the torsion spring 506 rebounds the baffle 504 to its initial position. At this time, the electromagnet 509 is reconnected and generates magnetism, which adsorbs the iron sheet 510 on the baffle 504, so that the escape duct 2 is closed again, thereby blocking the shock wave generated in the accident. Before the staff enters the escape duct 2 to escape, they need to grab the grab ring 604. The grab ring 604, in cooperation with the slider 603 and the guide rod 602, can guide the escape trajectory. At the same time, the grab ring 604 can keep the staff's body stable, avoiding flipping inside the escape duct 2, causing them to lose their sense of direction and lose the best escape time. After escaping from the escape duct 2, the sponge pad 607 cushions the staff to prevent them from falling.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
