Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and in particular relates to a safety device for an elevator. Background Art

[0002] Elevators are important equipment in buildings. In order to ensure the safe operation of elevators, monitoring equipment is needed to monitor the operating parts of the elevators. The existing comprehensive safety monitoring equipment for elevators basically has the advantages of low energy consumption, high image display clarity, low installation cost, solid structure, and long service life, which can meet the needs of safety monitoring of elevators.

[0003] For example, patent application number CN202220379263.8 discloses a comprehensive safety monitoring device for a building elevator, including a device body, the device body including a support ring, a ball cover and a motor, a support rod is installed on one side of the motor, a tooth pattern is provided on the outer side of the top of the support ring, a gear is installed on the bottom of the motor, a bayonet is provided on one side of the ball cover, a light-transmitting plate is clamped on the inner side of the bayonet, a ball is clamped on the inner side of the support ring, a lens is bonded to the bottom of the ball cover, and a camera 1 and a camera 2 are installed on the ball cover. The comprehensive safety monitoring device for the building elevator can use the lighting in the elevator to increase the brightness of the light in the elevator shaft, without the need to install additional lighting equipment to reduce the consumption of electricity, and can use multiple groups of light for multi-angle lighting work to avoid unclear visibility of some mechanisms due to obstruction by various equipment in the elevator shaft, thereby ensuring the quality of safety monitoring and the safety of the elevator, and is suitable for safety monitoring of building elevators.

[0004] In the prior art, light-transmitting plates and lenses are used to complete monitoring lighting processing without installing lighting equipment, thereby improving the security monitoring effect. However, there are still some shortcomings in the overall use process:

[0005] When the elevator is in use, in addition to the dark environment, it is easy to stir up dust on the outside of the elevator during the up and down movement. Over time, the dust is easy to adhere to the detection end surface of the monitor. In the prior art, since the monitoring device is set at the top or bottom of the elevator and is in a long-term moving state, it is not easy to install too many cleaning structures, resulting in the inability to ensure the monitoring quality;

[0006] In the prior art, the structure for driving the ball cover to rotate is arranged outside. When the elevator is moving, the dust stirred up easily adheres to the outside of the driving structure, affecting the driving stability, resulting in the need for manual maintenance multiple times in a short period of time, affecting the user experience. Utility Model Content

[0007] In order to overcome the deficiencies of the prior art, the utility model provides a safety device for an elevator. The utility model utilizes the air convection generated when the elevator moves upward through the settings of a ventilation pipe, a curved bottom plate, and a jet seat, and collects and compresses the air convection, so that high-pressure gas can flow outside the camera, which can not only clean the outside of the camera but also prevent dust and dirt from sticking. The setting of the secondary cleaning component improves the cleaning quality, and the setting of the drive protection component ensures that the device can stably complete the monitoring and detection processing.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0031] Embodiment 1:

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a lift safety device comprises a base 10 and a turntable 11. The turntable 11 is rotatably arranged on the upper end surface of the base 10, and a box 12 is arranged on the upper end surface of the turntable 11. A drive seat 14 is arranged on each side end surface of the box 12, and a camera 13 is rotatably arranged in the drive seat 14. A jet seat 16 is arranged on the end surface of the box 12 above each camera 13, and a plurality of jet nozzles 20 are connected to the bottom of the jet seat 16. A ventilation pipe 23 is arranged inside the box 12 on one side of the jet seat 16, and the jet seat 16 and the ventilation pipe 23 are connected to each other. A trumpet nozzle 17 is arranged on the upper end surface of the ventilation pipe 23, and a detachable filter plate 18 is arranged in the trumpet nozzle 17. A secondary cleaning component is arranged on the end surface of the turntable 11 below the filter plate 18, and a drive protection component is arranged between the turntable 11 and the base 10.

[0033] Specifically, a plurality of holes for fixing are arranged on the end face of the base 10, so that the device can be installed and fixed on the top end face of the elevator. The turntable 11 is rotatably arranged on the end face of the base 10 as a whole. The box 12 on the upper end face can be driven to complete multiple angle adjustments by driving the protection component, so that the cameras 13 inside the multiple drive seats 14 on each side end face of the box 12 can monitor and process the elevator motion structure, thereby ensuring the safe operation of the elevator. In this solution, the drive seat 14 and the camera 13 are both existing technologies. The drive seat 14 can drive the camera 13 to adjust a certain angle, so that the camera 13 can effectively monitor the various working structures above the elevator. The specific adjustment mechanism and monitoring technology are not elaborated in this solution.

[0034] When the elevator is moving upward, since the device is arranged at the top of the elevator, the elevator will also push the device to move upward. The gas outside the elevator will generate convection due to the movement of the elevator, thereby causing the gas to flow outside the device. At this time, the bell mouth 17 on the upper end face of the ventilation pipe 23 will inject the gas into the ventilation pipe 23. The detachable filter plate 18 in the bell mouth 17 can intercept and filter dust and dirt. The bell mouth 17 is wide at the top and narrow at the bottom, which has a certain effect of gathering gas. When a large amount of gas is injected into the ventilation pipe 23, the ventilation pipe 23 will distribute the gas to multiple The inside of the connected jet seat 16 is then sprayed downwardly from a plurality of jet nozzles 20 on the bottom end face of the jet seat 16. In the present embodiment, the upper and lower end faces of the jet nozzle 20 are both in the shape of a trumpet, which can perform secondary compression on a large amount of gas injected and then spray it outward, so that the pressure of the sprayed gas is effectively enhanced. At this time, the camera 13 can be rotated upward, so that the dirt on the end face of the camera 13 can be cleaned, thereby improving the monitoring effect. If the camera 13 does not rotate upward, a gas flow layer can also be formed outside the camera 13, so that dust and dirt cannot be effectively adhered to the outside of the camera 13, thereby ensuring real-time monitoring effect.

[0035] In the above process, if the device is used for a long time and is in regular maintenance, the staff can disassemble the filter plate 18 and replace it, or start the secondary cleaning component to perform secondary cleaning on the camera 13, thereby improving the cleaning efficiency.

[0036] Further, such as Figure 4 and Figure 7 As shown, the drive protection assembly includes a bearing seat 26 arranged on the upper end surface of the base 10, one end of a rotating shaft 27 is rotatably connected to the bearing seat 26, and the other end of the rotating shaft 27 is interconnected with the turntable 11, and a gear ring 36 is arranged on the outside of the bearing seat 26 on the bottom end surface of the turntable 11, a gear 28 is rotatably arranged on one side of the gear ring 36, and the gear 28 is connected to the gear ring 36, and a drive motor 29 is arranged on the end surface of the base 10 below the gear 28, and the output end of the drive motor 29 is connected to the end surface of the gear 28.

[0037] Specifically, a bearing seat is provided inside the bearing seat 26, so that the rotating shaft 27 can rotate smoothly. When the turntable 11 needs to be adjusted in angle, the output end of the driving motor 29 drives the gear 28 to rotate, thereby driving the gear ring 36 meshing with the gear 28 to rotate, thereby driving the turntable 11 above the gear ring 36 to rotate. In this relationship, the driving motor 29 is a prior art and will not be elaborated in detail in this solution.

[0038] Further, such as Figure 6 As shown, the drive protection assembly also includes a support ring 33 arranged on the end face of the base 10, an annular groove 35 is arranged on the outer circumferential surface of the support ring 33, a rotating ring 34 is rotatably connected in the annular groove 35, and an annular plate 21 is connected to the outside of the rotating ring 34, and one end of the top of the annular plate 21 is connected to the end face of the turntable 11.

[0039] Specifically, the support ring 33 and the annular plate 21 are both in a ring shape. The support ring 33 is fixedly connected to the end face of the base 10, and the annular plate 21 is fixedly connected to the bottom end face of the turntable 11. When the turntable 11 rotates, the turntable 11 will drive the bottom annular plate 21 to rotate, thereby driving the rotating ring 34 on the inner end face of the annular plate 21 to rotate inside the annular groove 35. The support ring 33 performs rotational support on the annular plate 21 through the annular groove 35. On the other hand, a relatively sealed structure is formed between the support ring 33 and the annular plate 21, which can prevent dust and dirt in the working environment of the elevator from entering the inside of the turntable 11 and the base 10, thereby ensuring the stable operation of the device.

[0040] Further, such as Figure 5 As shown, a rotating rod 31 is disposed inside each air-injection seat 16 , and a rotating impeller 32 is rotatably disposed outside each rotating rod 31 .

[0041] Specifically, multiple rotating rods 31 are arranged inside the jet seat 16. When a large amount of gas is poured into the ventilation pipe 23 to distribute the gas to the multiple jet seats 16, the gas flowing into the jet seat 16 will drive the rotating fan wheel 32 outside the rotating rod 31 to rotate, so that the flow efficiency of the gas can be improved by rotating the rotating fan wheel 32, so that the gas pressure ejected from the multiple jet pipe openings 20 at the bottom of the jet seat 16 can be improved, thereby ensuring the cleaning effect.

[0042] Further, such as Figure 2 As shown, fill lights 15 are provided on both sides of each camera 13 on the end surface of the box 12 .

[0043] Specifically, when the camera 13 monitors the outside of the elevator, the plurality of fill lights 15 can be turned on to perform fill light processing, so that the overall monitoring of the camera 13 can be more accurate.

[0044] Further, such as Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the secondary cleaning component includes a plurality of liquid spray seats 19 arranged on one side of the camera 13, and a plurality of liquid spray nozzles 22 are arranged on the end face of each liquid spray seat 19. A liquid storage seat 25 is arranged on one side of the liquid spray seat 19 in the box body 12, and the liquid spray seat 19 and the liquid storage seat 25 are connected to each other.

[0045] Specifically, a connectable main pipeline is provided on the outside of the liquid storage seat 25. When the elevator is shut down for maintenance, the staff can connect a water pump on the outside of the main pipeline to pour the cleaning liquid into the liquid storage seat 25. The liquid storage seat 25 will then distribute the cleaning liquid to each spray seat 19. The end faces of the multiple spray seats 19 with spray nozzles 22 are inclined upward, so that the spray nozzles 22 can spray the cleaning liquid upward onto the end face of the camera 13, thereby performing a secondary cleaning treatment on the camera 13.

[0046] Further, such as Figure 4 As shown, a control unit 30 is disposed in the box 12 .

[0047] Specifically, the control unit 30 is disposed above the liquid storage seat 25 and can control various operations of the device, thereby ensuring stable operation of the device.

[0048] Embodiment 2:

[0049] like Figure 4 As shown, a safety device for an elevator is provided, and a curved bottom plate 24 is arranged on the bottom end surface of the ventilation pipe 23.

[0050] As a further embodiment, the curved bottom plate 24 is in the shape of an upward curved surface as a whole. When the gas is injected into the ventilation pipe 23, it will flow directly to the bottom of the ventilation pipe 23 due to the pressure, and then flow along the curved surface of the curved bottom plate 24 toward the connecting port between the ventilation pipe 23 and the jet seat 16, thereby achieving a diversion effect, so that the gas can be smoothly injected into multiple jet seats 16.

[0051] Embodiment three:

[0052] like Figure 4 and Figure 8 As shown, a safety device for an elevator is provided, wherein a support frame 37 is connected to the outside of the filter plate 18, the outer circumferential surface of the support frame 37 abuts against the inner circumferential surface of the bell mouth 17, and a plurality of fixed mouths 38 are provided on the outer circumferential surface of the bell mouth 17.

[0053] As a further embodiment, multiple filter plates 18 are fixedly connected at the center of the support frame 37. When the filter plate 18 needs to be installed, the staff can press the support frame 37 into the end face of the trumpet nozzle 17, and then insert the bolts or other fixing parts into the fixed nozzle 38. One end of the fixing part abuts against the outer circular surface of the support frame 37, so that the filter plate 18 and the support frame 37 can be fixed. When disassembly is required, the fixing part is taken outward, and the filter plate 18 and the support frame 37 can be taken away. By setting the fixed nozzle 38 and the support frame 37, the overall disassembly and maintenance of the filter plate 18 is easier, thereby improving the maintenance efficiency.
