Description

Technical Field

[0001] This utility model relates to the field of air conditioner protection technology for excavators, and in particular to a structure for preventing water from entering the air conditioner of an excavator. Background Technology

[0002] In the construction machinery industry, to adapt to the increasingly hot summer environment, most construction machinery is now equipped with air conditioning systems as standard, especially excavators that do not move or have frontal drafts during operation. Air conditioning systems work by drawing in air from the outside, exchanging energy, and then blowing out cool air. However, excavators often operate in outdoor environments, and the problem of water ingress from outside air into the outdoor unit has long plagued equipment reliability. Existing air conditioning equipment often uses fixed dust filters or louvers for protection, which cannot dynamically respond to environmental changes, has poor water mist handling capabilities, and relies on electronic sensors for drainage control. In construction machinery like excavators, vibration and low-temperature operating conditions can easily lead to malfunctions. Therefore, there is an urgent need for a structure for excavators that prevents water from entering the air conditioning system. Utility Model Content

[0003] The purpose of this utility model is to address the deficiencies in the existing technology by proposing a structure for preventing water from entering the air conditioner of an excavator.

[0023] 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.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example 1: Refer to Figure 1-4 A structure for preventing water from entering the air conditioner of an excavator includes a support base 1, wherein the support base 1 is provided with an air intake adjustment mechanism 2, a waterproof structure 3 and a support platform 4.

[0026] The support platform 4 is used to connect to the outdoor unit of the air conditioner;

[0027] The support base 1 has a drainage groove 5 inside, and the drainage groove 5 has several water storage pipes 6 that cooperate with the air intake adjustment mechanism 2 and the waterproof structure 3. The top of the water storage pipes 6 is equipped with a confluence mounting bracket 7 that cooperates with the top wall of the support base 1. The water storage pipes 6 have a U-shaped structure, and the end of the water storage pipe 6 away from the confluence mounting bracket 7 is equipped with a float valve 8. It is easy to see from the above design that when external water flows or air is introduced, the structure collects water droplets, which seep into the air intake adjustment mechanism 2 and the waterproof structure 3, and fall onto the top wall of the support base 1. They then flow into the drainage groove 5 along the guide surface of the confluence mounting bracket 7. The accumulated water is distributed to multiple U-shaped water storage pipes 6 through the confluence mounting bracket 7. The U-shaped structure forms a water seal to prevent backflow of air. When the water level in the water storage pipes 6 reaches a certain height, such as 50mm, the float valve 8 is lifted by buoyancy and the drain outlet is opened, realizing water level-triggered drainage without electricity.

[0028] The regulating air intake mechanism 2 includes a gravity guide shroud 21. The gravity guide shroud 21 has a guide cavity 22 and a separation cavity 23 inside. The guide cavity 22 and the separation cavity 23 are arranged sequentially along the airflow direction. The guide cavity 22 has a plurality of evenly distributed guide blades 24 inside. The separation cavity 23 has a dividing air intake plate 25 in the middle position. The dividing air intake plate 25 has a triangular structure, and the inclination angles of the top and bottom walls of the separation cavity 23 correspond to the inclination angles of the dividing air intake plate 25.

[0029] The guide vane 24 is inclined on one side near the air intake and has several grooves 241. The axis of the grooves 241 is inclined to the axis of the guide vane 24, and the angle between the axis of the grooves 241 and the axis of the guide vane 24 is 30°. The grooves 241 are inwardly concave arc-shaped structures.

[0030] The bottom end of the guide vane 24 away from the gravity guide shroud 21 is provided with several counterweight adjustment rods 242. Several brush sections 243 are provided on one side of each counterweight adjustment rod 242. The brush sections 243 are mounted on the guide vane 24 with screws. From the above design, it is easy to see that in the dry air intake state, by adding or removing the counterweight adjustment rods to control the counterweight, the guide vane 24 maintains a 30° opening angle under the gravity of the counterweight adjustment rods 242, maximizing air intake efficiency. When the intake airflow contains a large amount of moisture, the surface of the vane is coated with... After the water increases in weight, some of the water is collected by the groove. The imbalance of the weight triggers the blades to close to 75°. The inclined design of the groove 241 can quickly drain the water flow. After the airflow enters the separation chamber 23, it is guided by the triangular segmented air intake plate 25 to form a dual-channel vortex. Centrifugal force throws the water droplets against the chamber wall and flows into the drainage groove 5 along the inclined wall. The airflow speed through the separation chamber 23 will increase and can maintain a straight passage, so that the heavier water moves straight under the action of inertia. The brush section 243 periodically cleans the gap with the movement of the blades to prevent mud blockage.

[0031] Example 2: Based on Example 1, the waterproof structure 3 includes a filter cover 301 connected to the gravity guide cover 21. The filter cover 301 has three filter plates 302 inside. The filter plates 302 are respectively disposed on the inner top wall and inner bottom wall of the filter cover 301 and correspond to the air outlet direction of the separation chamber 23.

[0032] The filter plates 302 are arranged in a Z-shaped zigzag pattern, with two filter plates 302 disposed on the inner top wall of the filter cover 301 and the other filter plate 302 disposed on the inner bottom wall of the filter cover 301. A rotating shaft 303 is provided at the connection between the filter plates 302 and the filter cover 301.

[0033] The surface of the filter plate 302 is provided with a plurality of filter teeth 304, and a plurality of fiber felts 305 are provided on the filter teeth 304. The plurality of fiber felts 305 cover the surface of the filter plate 302. It is not difficult to see from the above design that the airflow processed by the separation chamber 23 enters the filter cover 301 and forms multiple 110° sharp turns between the Z-shaped filter plates 302. The residual water droplets impact the filter teeth 304 due to inertia and are adsorbed by the fiber felts 305. After the adsorbed water reaches the fiber felts 305, it is agglomerated into water droplets due to the vibration of the airflow and slides into the drainage groove 5 along the surface of the Z-shaped plate. The filter plate 302 achieves a slight swing through the rotating shaft 303, which enhances the desorption efficiency of the fiber felts 305. The filter teeth 304, through the serrated structure distribution, disrupt the surface tension of the water flow and prevent the fiber felts 305 from caking.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
