DETAILED DESCRIPTION

[0027] In order to make the person skilled in the art better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.

[0028] It should be noted that, in the case of no conflict, the embodiments and the features and technical solutions in the embodiments in the present application can be combined with each other.

[0029] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0030] Embodiment, please refer to Figures 1-5A ventilation device for an elevator car includes a car top wall 1 with a ventilation opening 102. A ventilation mechanism 2 connects the ventilation opening 102 to the car top wall 1. The ventilation mechanism 2 includes a limiting frame 203 inserted into the inner wall of the ventilation opening 102. A support frame 201 is fixedly installed on the top of the limiting frame 203. A ventilation structure is provided on the top of the support frame 201. Several limiting members are provided between the support frame 201 and the car top wall 1. The limiting members include a groove 202 provided on the support frame 201 and a connecting rod 103 fixedly installed on the car top wall 1. A turntable 104 is mounted on the outer surface of 103 via a bearing. A baffle 105 is fixedly connected to the outer surface of the turntable 104 and inserted into the groove 202. This application achieves the limiting stop of the support frame 201 by inserting the baffle 105 into the groove 202. Rotating the baffle 105 to separate the baffle 105 from the groove 202 can release the limiting stop of the support frame 201, thereby facilitating the removal of the support frame 201 and ventilation structure from the car top wall 1. This allows cleaning and maintenance work to be carried out outside the hoistway, where the space outside the hoistway is spacious, the working environment is good, and it is safer.

[0031] Furthermore, a damping pad 106 is fitted on the outer surface of the connecting rod 103. The two ends of the damping pad 106 abut against the car top wall 1 and the turntable 104, respectively. The damping pad 106 can be made of rubber. Through the damping effect between the damping pad 106 and the turntable 104, the turntable 104 can be limited to prevent it from rotating on its own, thereby improving the stability of the turntable 104 and the baffle 105.

[0032] Furthermore, the ventilation structure includes a fan frame 204 bolted to the support frame 201. The operation of the bolts between the fan frame 204 and the support frame 201 is carried out outside the shaft, which is safer. A ventilation fan is installed inside the fan frame 204 for ventilation purposes.

[0033] Furthermore, a protective net 205 is installed on the fan bracket 204. The protective net 205 is located above the ventilation fan and can protect the ventilation fan.

[0034] During cleaning and maintenance, rotate the turntable 104 to separate the baffle 105 from the groove 202, and pull the support frame 201 upward to separate the limiting frame 203 from the ventilation opening 102. Then, the support frame 201 and the ventilation structure can be removed from the top wall 1 of the car. Move the support frame 201 and the ventilation structure outside the hoistway for cleaning and maintenance. It is safer outside the hoistway. During installation, insert the limiting frame 203 into the ventilation opening 102, and rotate the turntable 104 to connect the baffle 105 with the groove 202.

[0035] Further, the support frame 201 is provided with a wind guide assembly, which can adjust the wind direction of the ventilation fan.

[0036] Further, the wind guide assembly comprises a plurality of first connecting shafts 206 arranged in the support frame 201 through bearings, and the outer surfaces of the plurality of first connecting shafts 206 are fixedly sleeved with wind guide plates 207 located in the support frame 201. The wind guide plates 207 can be supported by the first connecting shafts 206, and the wind guide operation can be performed by the wind guide plates 207.

[0037] Further, one end of each of the plurality of first connecting shafts 206 extends from one side of the support frame 201, and an adjusting member is arranged between the plurality of first connecting shafts 206 and the support frame 201. The adjusting member is used to adjust the angle of the wind guide plate 207 through the first connecting shaft 206, so as to adjust the wind direction.

[0038] Further, the adjusting member comprises a plurality of first connecting plates 208, each of which is fixedly connected with one end of the first connecting shaft 206. A second connecting shaft 210 is fixedly connected to each of the plurality of first connecting plates 208. A second connecting plate 209 is rotatably connected between the plurality of second connecting shafts 210 through bearings. During the movement of the second connecting plate 209, the first connecting shaft 206 can be driven to rotate by the second connecting shaft 210 and the first connecting plate 208, and the wind guide plate 207 can be driven to rotate by the first connecting shaft 206 to adjust the angle of the wind guide plate 207.

[0039] Further, a fixing member is arranged between the support frame 201, the second connecting plate 209, and one of the first connecting plates 208.

[0040] Further, the fixing member comprises a fixed plate 211 fixedly installed on the side surface of the support frame 201. An arc-shaped slot 212 is formed in the fixed plate 211. A third connecting plate 215 is slidably connected to the side surface of the fixed plate 211. A hand screw bolt 213 is connected between the third connecting plate 215 and the fixed plate 211. A hand screw nut 214 is threadedly connected to the hand screw bolt 213. One end of the third connecting plate 215 is fixedly connected with one of the first connecting plates 208. An arc slot 216 is formed in the third connecting plate 215. A third connecting shaft 217 is slidably connected to the inner wall of the arc slot 216, and one end of the third connecting shaft 217 is fixedly connected with the second connecting plate 209. After loosening the hand screw nut 214 and the hand screw bolt 213, the second connecting plate 209 can be pushed and pulled to drive the second connecting plate 209 to move horizontally. After tightening the hand screw nut 214 and the hand screw bolt 213, the position of the second connecting plate 209 can be fixed, and the first connecting shaft 206 can be fixed. The second connecting plate 209 and the fixed plate 211 are not in the same plane, so there is no interference between the fixed plate 211 and the second connecting plate 209.
