Description

Technical Field

[0001] This utility model relates to the field of elevators, and in particular to a waterproof outdoor elevator car. Background Technology

[0002] Existing outdoor elevator waterproofing designs primarily rely on sealing structures (such as sealing strips and waterproof adhesives). However, these structures are susceptible to temperature changes, mechanical wear, and aging, leading to decreased sealing performance. Rainwater can still seep into the car through gaps between the car door and landing door. Furthermore, traditional designs have low drainage efficiency at the top of the car, allowing water to backflow through gaps or drainage holes, further exacerbating the risk of leakage. To address these issues, some existing technologies attempt to improve waterproofing by optimizing drainage structures or adding rain shields, but with limited effectiveness. For example, simple drainage channel designs cannot cope with heavy rainfall or high wind speeds, while mechanical rain shields suffer from complex structures and high maintenance costs. For instance, CN220950745U discloses an outdoor sightseeing elevator, which has the following shortcomings in outdoor waterproofing: it cannot prevent rainwater from flowing into the car through gaps between the landing door and car door. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model aims to provide a waterproof outdoor elevator car, solving the problems present in existing technologies. This device uses an air curtain mechanism to form a high-speed airflow barrier at the top of the car door, actively preventing rainwater from entering through gaps, without relying on fragile physical sealing structures. In traditional designs, the drainage efficiency at the top of the car is low, and accumulated water may backflow into the car interior through top gaps or drainage holes. This device creates a low-pressure zone at the top of the car through an air curtain mechanism, attracting rainwater to move upwards, and accelerates top drainage through a specially designed air curtain box, reducing water retention. This device uses a high-speed airflow driven by a centrifugal fan to forcibly guide rainwater upwards, forming a dynamic waterproof barrier that can adapt to various harsh weather conditions. It also features a compact structure, high reliability, and an integrated ventilation mechanism to ensure ventilation inside the car.

Detailed Implementation

[0027] The following will refer to the appendix in the example of this utility model. Figure 1 -Appendix Figure 10 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] like Figure 1 As shown, this utility model provides a technical solution: an outdoor waterproof elevator car, including a car 1, a car door 2 installed at the front of the car 1, an air curtain mechanism 3 installed at the top of the car door 2, a load-bearing frame 4 fixed to the bottom of the car 1, and a suspension mechanism 5 fixed to the upper end of the load-bearing frame 4; the car 1, as the main load-bearing component of the elevator, is used to carry passengers or goods. The car door 2 is installed at the front of the car 1 for passengers to enter and exit the car 1, serving a sealing and protective function. The air curtain mechanism 3 forms a high-speed airflow barrier at the top of the car door 2, actively preventing rainwater from seeping in from the gap between the car door 2 and the landing door; it also forms a low-pressure zone at the top of the car 1, accelerating the movement of rainwater to the top and its discharge. The load-bearing frame 4 is fixed to the bottom of the car 1, bearing the weight of the car 1 and its internal load. The suspension mechanism 5 is fixed to the upper end of the load-bearing frame 4, used to suspend the car 1, allowing the car 1 to move up and down within the hoistway.

[0029] like Figure 2 and Figure 3 As shown, the air curtain mechanism 3 includes a housing 301, a centrifugal fan 302 fixed inside the housing 301, an air inlet pipe 303 fixed to the side of the centrifugal fan 302, an air curtain box 304 fixed to the top of the car 1, and an air outlet pipe 305 connecting the centrifugal fan 302 and the air curtain box 304. The housing 301 protects the centrifugal fan 302 and other internal components, providing a relatively enclosed space. The centrifugal fan 302 is driven by a motor to rotate the centrifugal fan blades, generating a high-speed airflow. This provides power to the air curtain mechanism 3, enabling the air curtain to perform its waterproof and drainage functions. The air inlet pipe 303 introduces outside air into the centrifugal fan 302, ensuring sufficient air supply for the centrifugal fan 302 to operate normally. The air curtain box 304 receives the airflow generated by the centrifugal fan 302 and directs the airflow in different directions through multiple air outlets, forming an air curtain. The air outlet pipe 305 connects the centrifugal fan 302 and the air curtain box 304, delivering the airflow generated by the centrifugal fan 302 to the air curtain box 304.

[0030] like Figure 4 As shown, the centrifugal fan 302 includes a motor bracket 3021 bolted to the top of the car 1, a motor 3022 fixed to the motor bracket 3021, a centrifugal housing 3023 fixed to the outside of the motor 3022, and centrifugal fan blades 3024 fixed to the side of the motor 3022. The motor bracket 3021 secures the motor 3022 to the top of the car 1, providing stable support and ensuring the stability of the motor 3022 for normal operation. The motor 3022 drives the centrifugal fan blades 3024 to rotate, providing power to the centrifugal fan 302 and enabling it to generate high-speed airflow. The centrifugal housing 3023 encloses the centrifugal fan blades 3024, guiding the airflow direction. Driven by the motor 3022, the centrifugal fan blades 3024 rotate, generating centrifugal force, drawing in air and accelerating its discharge, thus providing high-speed airflow to the air curtain mechanism 3.

[0031] like Figure 5 As shown, the centrifugal housing 3023 has a diversion port 3026 on the air inlet side; the diversion port 3026 diverts the incoming air, so that a portion of the air flows into the car 1 and introduces external air into the car 1 to form ventilation.

[0032] like Figure 6 and Figure 7As shown, the air curtain box 304 has an air inlet 3041 connected to the air inlet pipe 303 at its rear end, a rear air outlet 3042 at its rear end, a first baffle 3043 at the upper end of the rear air outlet 3042, an upper air outlet 3044 at the upper end of the air curtain box 304, a front air outlet 3045 at the front end of the air curtain box 304, and a second baffle 3046 at the lower end of the front air outlet 3045. The air inlet 3041 is the opening at the rear end of the air curtain box 304, connected to the air inlet pipe 303, and is used to receive airflow. This ensures that airflow can smoothly enter the air curtain box 304. The rear air outlet 3042 mainly cooperates with the first baffle 3043 to blow the airflow to the top of the car 1, so that the water flow is quickly blown to the rear of the car 1, achieving the purpose of rapid drainage. The upper air vent 3044 mainly forms an air curtain, which draws the falling rainwater into the air curtain, reducing the amount of rainwater falling into the gap between the car door 2 and the hall door. The front air vent 3045 works in conjunction with the second baffle 3046 to form an upward air curtain at the upper part of the car door 2, blowing the rainwater above and preventing it from falling into the gap between the car door 2 and the hall door.

[0033] like Figure 8 As shown, the air curtain box 304 is provided with a third baffle 3047 inside, and the third baffle 3047 is provided with an opening 3048. The third baffle 3047 can ensure that the rear air outlet 3042 and the front air outlet 3045 have sufficient air pressure, and then blow it out from the upper air outlet 3044 through the opening 3048, forming a low-pressure area in the upper part of the car 1, attracting air and rainwater, thereby reducing the amount of rainwater at the upper part of the car door 2.

[0034] like Figure 9 As shown, a first air vent 101 is provided on the side of the car 1, and a water outlet 102 is provided at the lower end of the first air vent 101; the first air vent 101 is the air inlet of the centrifugal fan 302, which is used for the centrifugal fan 302 to draw in fresh air from the outside.

[0035] like Figure 10 As shown, a second air vent 3011 is provided on the side of the outer casing 301, and a drain pipe 3012 is provided at the lower end of the second air vent 3011. A fourth baffle 3013 is provided inside the outer casing 301, and an exhaust vent 3014 is provided on the side of the outer casing 301. The second air vent 3011 is used to draw in air that has passed through the first air vent 101, so that the outside air reaches the centrifugal fan 302. The diversion port 3026 on the side of the centrifugal fan 302 diverts the outside air drawn in, and part of it enters the outer casing 301. The drain pipe 3012 is used to discharge the drawn-in moisture. The fourth baffle 3013 can retain water mist inside the outer casing 301, so that the drawn-in air is discharged from the exhaust vent 3014.

[0036] Working principle:

[0037] Motor 3022 drives centrifugal fan blades 3024 to rotate, generating high-speed airflow. The airflow enters the centrifugal housing 3023 through intake pipe 303. Part of the air enters the car 1 through diversion port 3026, achieving car ventilation; the other part is delivered to air curtain box 304 through exhaust pipe 305. The airflow within air curtain box 304 forms a dynamic waterproof barrier through three air outlets: Rear air outlet 3042: Airflow is guided to the top of the car via first baffle 3043, accelerating the discharge of rainwater from the top. Upper air outlet 3044: The upward-spraying high-speed airflow forms a vertical barrier at the top of car door 2, preventing rainwater from falling in through the gap between the car door and the landing door. Front air outlet 3045: The downward-sloping airflow, in conjunction with the second baffle 3046, forms an upward airflow at the top of the car door, further preventing rainwater infiltration. The high-speed airflow from the top air vent 3044 creates a low-pressure zone (Bernoulli effect) at the top of the car, attracting surrounding rainwater to gather at the top and reducing rainwater retention in the car door area.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
