DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Embodiment one:

[0033] The present application provides a technical solution: an energy-saving explosion-proof elevator, comprising a car body 1, wherein the car body 1 is matched with a regenerative brake, and energy efficient utilization is realized through the regenerative brake;

[0034] and an efficient motor and control system to reduce energy consumption and achieve the overall energy-saving effect of the explosion-proof elevator; the above content is all prior art known to those skilled in the art, and therefore will not be described here.

[0035] The car body 1 is provided with two elevator doors 2, one surface of one of the elevator doors 2 is provided with an observation window 3, an observation module 4 for facilitating the user inside the car body 1 to safely check the environment outside the car body 1 is installed in the observation window 3, and a sealing strip 5 for sealing the edge of the inner wall of the observation window 3 is fixedly connected to the inner wall of the observation window 3;

[0036] The observation module 4 comprises a protective cover 51 movably clamped in the observation window 3 and a bottom shell 6 covered by the protective cover 51 and fixedly connected in the observation window 3, an inner wall of the bottom shell 6 on the side facing the protective cover 51 is slidably connected with a moving seat 7, a metal protective cover plate 8 is covered on the side of the moving seat 7 facing the protective cover 51, a through hole one 9 covered by the metal protective cover plate 8 and in one-way sealing is formed on the surface of the moving seat 7 opposite to the metal protective cover plate 8, and a through hole two 10 in communication with the through hole one 9 is formed on the side of the bottom shell 6 away from the protective cover 51.

[0037] Working principle of the embodiment one:

[0038] Reference Figure 1 - Figure 5 ;

[0039] After the explosion, the personnel are trapped in the car body 1, in order to pre-judge whether the air environment outside is suitable for people to stay for a long time, it is necessary to pre-judge the air in the external space, the simplest way is to smell the air in the external environment, to judge whether there is irritating smell in the external air, to make a simple judgment, and to open the elevator door 2 will cause a large amount of air in the external environment to enter the car body 1, which exists a safety hazard;

[0040] Therefore, a small amount of air in the external environment needs to be introduced and smelled.

[0041] In the case that the through hole one 9 is not sealed by the metal protective cover plate 8, the external environment is communicated through the through hole one 9 and the through hole two 10, and then when the metal protective cover plate 8 moves quickly and is separated from the sealing of the through hole one 9, according to Bernoulli's principle, the quick movement of the metal protective cover plate 8 will introduce a small amount of air from the external environment into the car body 1 through the through hole two 10 and the through hole one 9, at this time, the user's nose close to the through hole one 9 can make a simple judgment on the air condition in the external environment through a small amount of air entering.

[0042] Secondly, before this, the metal protective cover plate 8 has been sealing the through hole one 9, even the shock wave generated by the explosion will not cause the metal protective cover plate 8 to be loose.

[0043] Before the metal protective cover plate 8 moves, the user in the car body 1 needs to manually take out the protective cover 51 from the observation window 3 to remove the sealing protection of the observation module 4 as a whole.

[0044] In the embodiment two, a transparent explosion-proof glass sheet 11 for secondary sealing of the through hole one 9 is limitingly and slidably connected on the side of the moving seat 7 close to the protective cover 51.

[0045] From the foregoing, after the metal protective cover plate 8 is separated from the moving seat 7 and the seal of the through hole 9 is released, the through hole 9 needs to be sealed again for the safety of the user; and by moving the transparent explosion-proof glass sheet 11 on the moving seat 7 in the direction indicated by the arrow B, the through hole 9 can be sealed again to protect the user in the car body 1.

[0046] In the third embodiment, the bottom shell 6 is provided with a transmission device I for driving the metal protective cover plate 8 to separate from the moving seat 7 and release the seal of the through hole 9, which comprises a vertical plate 12 fixed on the bottom shell 6, a shaft I 13 fixedly connected to the surface of the vertical plate 12, a torsion spring 14 sleeved on the shaft I 13 and fixed at one end of the vertical plate 12, a shaft sleeve 15 penetrating and being rotationally connected to the shaft I 13 and being limited in position, a rotation arm 16 fixedly connected to the arc-shaped contour of the shaft sleeve 15 and being in a locked state, the other end of the torsion spring 14 being fixedly connected to the end of the shaft sleeve 15, an extension strip 17 fixedly connected to the surface of the rotation arm 16, a shaft II 18 fixedly connected to the lower surface of the end of the extension strip 17 away from the rotation arm 16, and the bottom of the shaft II 18 being fixedly connected to the upper surface of the metal protective cover plate 8.

[0047] The working principle of the third embodiment is as follows:

[0048] Reference Figure 5 At this time, the rotation arm 16 is in a locked state, the rotation arm 16 is parallel to the moving seat 7, and the torsion spring 14 accumulates a large amount of elastic potential energy; the locking of the rotation arm 16 will be disclosed later;

[0049] Once the rotation arm 16 is unlocked, the unlocking content will be disclosed later, under the action of the elastic force of the torsion spring 14, the shaft sleeve 15, the rotation arm 16, the extension strip 17, the shaft II 18 and the metal protective cover plate 8 rotate around the shaft I 13 in the direction away from the moving seat 7 at a high speed, which can generate the above-mentioned Bernoulli effect and realize the small amount of external airflow entering;

[0050] The fourth embodiment is as follows:

[0051] The moving seat 7 is provided with a locking device for locking the horizontal state of the rotation arm 16, which comprises an impact block 19 sliding in the inner wall of the moving seat 7, a lock block I 20 fixedly connected to the upper surface of the impact block 19, a lock block II 21 fixedly connected to the lower surface of the end of the rotation arm 16 away from the shaft sleeve 15 and being engaged with the lock block I 20, and the moving seat 7 being driven to have a tendency to move horizontally towards the shaft sleeve 15.

[0052] The working principle of the fourth embodiment is as follows:

[0053] Reference Figure 6 Since the moving seat 7 is driven to have a tendency to move horizontally towards the shaft sleeve 15, that is, Figure 6In the direction of the arrow C, through the transmission of the impact block 19, the lock block one 20 will be in close contact with the lock block two 21, and the lock block two 21, the rotating arm 16 are locked, so that the rotating arm 16 cannot be rotated by the elastic potential energy of the torsion spring 14.

[0054] Further, the upper surface of the moving seat 7 is provided with an unlocking device, the unlocking device includes the unlocking block 22 fixed on the upper surface of the moving seat 7 away from the shaft sleeve 15, the top of the unlocking block 22 is provided with an inclined surface, and the inclined surface is arranged opposite to the end of the rotating arm 16 away from the shaft sleeve 15.

[0055] Reference Figure 6 , with the movement of the moving seat 7, the unlocking block 22 moves synchronously, and then the inclined surface on the unlocking block 22 is in contact with the end of the rotating arm 16 away from the shaft sleeve 15 and is extruded, and the end of the rotating arm 16 away from the shaft sleeve 15 is lifted, so that the rotating arm 16 can be rotated in the direction as described above, in Figure 6 , the specific rotating direction is shown by the arrow D; thus the unlocking operation of the rotating arm 16 is completed.

[0056] Further, the bottom shell 6 is provided with a driving device for moving the moving seat 7, the driving device includes the shaft three 23 penetrating through the bottom shell 6 and being limited by damping and being fixedly rotated on the bottom shell 6, the arc-shaped contour of the shaft three 23 is fixedly sleeved with the gear 24, and the teeth of the gear 24 are in transmission engagement with the toothed plate 25 fixed on the moving seat 7.

[0057] In use, the shaft three 23 is manually driven, after overcoming the resistance between the shaft three 23 and the bottom shell 6, the rotation of the shaft three 23 is realized, so that the shaft three 23 drives the synchronous rotation of the gear 24, and then drives the movement of the moving seat 7 and the toothed plate 25 in the bottom shell 6;

[0058] Further, the arc-shaped contour of the end of the shaft three 23 extending into the through hole two 10 and the through hole one 9 is fixedly connected with the heat-resistant brush 26. The model of the heat-resistant brush 26 is PA66, and the melting point is 200℃.

[0059] By rotating the shaft three 23, the synchronous rotation of the heat-resistant brush 26 is driven, and the transparent explosion-proof glass sheet 11 which is twice sealed in the through hole one 9 can be operated, as Figure 7 shown, at this time, the heat-resistant brush 26 is parallel to the bottom shell 6, and can completely shield the through hole one 9 and the transparent explosion-proof glass sheet 11, so as to avoid the dust and impurities in the air from falling on the transparent explosion-proof glass sheet 11 in the explosion;

[0060] When it is needed to observe the external environment through the transparent explosion-proof glass sheet 11, the heat-resistant brush 26 can be removed from the shielding protection of the transparent explosion-proof glass sheet 11 by slightly rotating the shaft three 23.

[0061] Further, the impact block 19 is fixedly connected with the transparent explosion-proof glass sheet 11.

[0062] In actual use, the rapid movement of the impact block 19 drives the synchronous rapid movement of the two transparent explosion-proof glass sheets 11, thereby realizing the secondary sealing of the through hole one 9 after a small amount of external gas enters the car body 1 through the through hole two 10 and the through hole one 9.

[0063] Further, the unlocking block 22 is penetrated and axially slidably connected with a shaft four 27, the shaft four 27 is penetrated through the unlocking block 22 and fixedly connected with the surface of the impact block 19, the arc-shaped contour of the shaft four 27 is sleeved with a compression spring 28, and the two ends of the compression spring 28 are fixedly connected with the opposite surfaces of the impact block 19 and the unlocking block 22.

[0064] Reference Figure 6 , Figure 6 The compression spring 28 in the impact block 19 accumulates elastic potential energy, which cannot overcome the frictional damping between the shaft three 23 and the bottom shell 6, so that the state shown in the impact block 19 can be continuously maintained. Figure 6

[0065] Once the heat-resistant brush 26 is unlocked to rotate in the direction indicated by the arrow D, the elastic force of the compression spring 28 is released, so that the impact block 19 can quickly slide in the inner wall of the moving seat 7;

[0066] Further, the inner wall of the bottom shell 6 below the shaft sleeve 15 is fixedly connected with a baffle 29 for limiting the movement of the impact block 19, the side of the baffle 29 facing the impact block 19 is fixedly connected with a liquid storage bag 30 for buffering the collision between the impact block 19 and the baffle 29, the liquid storage bag 30 contains cleaning liquid for washing the side of the transparent explosion-proof glass sheet 11 facing the through hole two 10, and the surface of the baffle 29 is penetrated and communicated with a liquid discharge pipe 31, one end of the liquid discharge pipe 31 away from the liquid storage bag 30 penetrates the moving seat 7 and extends to the transparent explosion-proof glass sheet 11 sealed after the through hole one 9.

[0067] Reference Figure 6 By providing the baffle 29, the movement of the impact block 19 is limited, and by providing the liquid storage bag 30 and the cleaning liquid in the liquid storage bag 30, the impact between the impact block 19 and the baffle 29 can be buffered and protected, and at the same time, due to the impact of the impact block 19, the washing liquid in the liquid storage bag 30 can be sprayed to the transparent explosion-proof glass sheet 11 through the liquid discharge pipe 31, thereby realizing further cleaning operation of the transparent explosion-proof glass sheet 11, and providing better observation experience for the user in the car body 1. The cleaning liquid can be pure water and is manually supplemented regularly.
