Description

Technical Field

[0001] This utility model relates to the technical field of air conditioning unit accessories for rail vehicles, specifically a rainwater separator. Background Technology

[0002] During operation, rail vehicle air conditioning units require rainwater separators installed at the air inlets on both sides to ensure ventilation and prevent rainwater and sediment from entering. Existing rainwater separators consist of a frame, a first waterproof filter element and a second waterproof filter element housed within the frame, with a ventilation gap between them. However, existing rainwater separators have poor rainproofing and air intake performance, failing to guarantee the normal operation of the rail vehicle air conditioning units and resulting in higher energy consumption. This is particularly problematic in cold and harsh environments, such as the Lanzhou-Xinjiang railway line in my country, where low temperatures cause snow to accumulate and freeze on the air conditioning units, affecting the rainwater separator's ventilation. Most existing rainwater separators for rail vehicle air conditioning units employ multi-layer waterproof filter elements combined with electric heating equipment to achieve rainwater separation and prevent icing. However, their multi-layer filter structure consists of multiple independent cylindrical filter elements, resulting in poor rainwater adsorption and diversion effects. Utility Model Content

The filter mounting bracket is fixedly installed inside the filter screen and the water-absorbing filter and the hydrophobic filter. An electric heating component is set inside the second fixed frame. The water-absorbing filter is located in front of the hydrophobic filter. A dustproof net is fixedly installed at the front opening of the second fixed frame. An absorbent sponge is laid on the bottom inner wall of the second fixed frame. The absorbent sponge is located between the water-absorbing filter and the dustproof net. A drainage groove is opened at the bottom of the dustproof net.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-6 This utility model provides a technical solution: a rainwater separator, including a fixed frame 1, a fixed frame 2 fixedly installed at the front end of the fixed frame 1, the fixed frame 2 being a trapezoidal platform shape with a larger front and a smaller rear.

[0022] Inside the fixed frame 1, a filter mounting bracket 3 is fixedly installed with screws. Inside the filter mounting bracket 3, a water-absorbing filter 4 and a water-repellent filter 5 are fixedly installed. An electric heating assembly 11 is installed inside the fixed frame 2. The water-absorbing filter 4 is located in front of the water-repellent filter 5. A dustproof net 7 is fixedly installed at the front opening of the fixed frame 2. An absorbent sponge 8 is laid on the bottom inner wall of the fixed frame 2, located between the water-absorbing filter 4 and the dustproof net 7. A drainage groove 9 is opened at the bottom of the dustproof net 7. A rear filter 6 is fixedly installed on the inner wall of the filter mounting bracket 3, located behind the water-repellent filter 5. The water-absorbing filter 4 absorbs moisture from the air. The hydrophobic filter 5 removes excess moisture from the air, improving drainage. A trapezoidal frame 2 is used to install the dustproof net 7 and the absorbent sponge 8. After the water-absorbing filter 4 and the hydrophobic filter 5 filter out the rainwater mixed in the air, the rainwater will flow outward along the inner wall of the frame 2. At this time, the absorbent sponge 8 will absorb the water, and the water inside the absorbent sponge 8 will also flow out from the absorbent sponge 8 under the action of gravity and then be discharged from the drainage channel 9. An electric heating component 11 is set to heat the water-absorbing filter 4 and the hydrophobic filter 5 to prevent water from freezing at the water-absorbing filter 4 and the hydrophobic filter 5. The rear filter 6 is a redundant design to ensure the filtration effect of the air.

[0023] A fixed frame 12 is fixedly installed at the rear end of the fixed frame 1. An air purification filter 13 is fixedly installed on the inner wall of the fixed frame 12. The air purification filter 13 is used to perform final purification on the air to be introduced into the air conditioning unit to prevent odors from entering the air conditioning unit.

[0024] A water guide plate 14 is fixedly installed on the bottom inner wall of the filter mounting frame 3. The water guide plate 14 is lower in the front and higher in the back, and the water guide plate 14 is located between the hydrophobic filter screen 5 and the rear filter screen 6. The water guide plate 14 is set to guide the rainwater in the filter mounting frame 3 forward, so that the rainwater flows from the fixed frame 1 to the fixed frame 2.

[0025] The electric heating assembly 11 includes a frame 1101, an electric heating wire 1102, and a controller 1103. The controller 1103 is fixedly installed in the filter screen mounting bracket 3. The frame 1101 is disposed between the water-absorbing filter screen 4 and the water-repellent filter screen 5, and the frame 1101 supports the water-absorbing filter screen 4 and the water-repellent filter screen 5. A groove is provided on the frame 1101, and the electric heating wire 1102 is installed in the groove. The frame 1101 is made of thermally conductive metal. The electric heating wire 1102 is electrically connected to the controller 1103. The controller 1103 controls the opening of the electric heating wire 1102, and the electric heating wire 1102 heats the frame 1101, thereby heating the water-absorbing filter screen 4 and the water-repellent filter screen 5.

[0026] A water baffle 10 is fixedly installed on the inner wall of the fixed frame 2. The water baffle 10 is arc-shaped and located behind the absorbent sponge 8. Multiple water baffles 10 are provided and are evenly distributed at the back opening of the fixed frame 2. When it rains outside, there is a lot of rainwater in the air. The water baffle 10 can block most of the rainwater, thereby reducing the workload of the water-absorbing filter screen 4 and the hydrophobic filter screen 5.

[0027] An electric heating rod 15 is installed on the back of the water baffle 10. The electric heating rod 15 is electrically connected to the controller 1103. The controller 1103 turns the air electric heating rod 15 on and off. The electric heating rod 15 heats the water baffle 10 to prevent ice from forming on the water baffle 10, thus preventing rainwater from passing through the gaps between the water baffles 10.

[0028] Working principle: When air enters from the fixed frame 2, it is first filtered by the dustproof net 7, which filters out branches, leaves, dust and garbage. Then, it passes through the water baffle 10, which blocks most of the rainwater. After passing through the water-absorbing filter 4, most of the rainwater is absorbed. Then, the rainwater is completely filtered out by the hydrophobic filter 5. After passing through the post-filter 6 and the air purification filter 13, the air enters the air conditioning unit. The rainwater blocked by the water-absorbing filter 4, the hydrophobic filter 5 and the water baffle 10 flows along the water guide plate 14 and the bottom inner wall of the fixed frame 2. When it flows to the absorption sponge 8, it is absorbed by the absorption sponge 8. The water in the absorption sponge 8 will also flow out from the absorption sponge 8 under the action of gravity and then be discharged from the drain trough 9.

[0029] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
