Description

Technical Field

[0001] The invention relates to the technical field of locomotives, and in particular to a non-powered window pneumatic mosquito-proofing structure based on the principle of fluid mechanics. Background Art

[0002] With the continuous development of railway transportation technology, the intelligence level of locomotives is increasing day by day, especially in the field of railway safety monitoring and long-range target recognition, the application of intelligent vision machines has become crucial. Intelligent vision machines are mainly used to identify obstacles, targets, etc. on the railway, and their imaging quality directly affects the recognition accuracy of the system. However, the existing intelligent vision equipment is easily interfered by pollutants such as mosquitoes and dust in the high-speed railway environment, especially at night, when the locomotive runs at high speed and the lights attract a large number of mosquitoes. These mosquitoes will bombard the windows of the vision machine when the vehicle is running at high speed, causing serious contamination of the lens surface. After mosquitoes adhere to the surface of the lens and mix with dirt such as floating dust, it is easy to form stains that are difficult to remove, which significantly reduces the clarity and quality of the image, affecting the recognition ability and efficiency of the intelligent vision system.

[0003] There are two main types of existing protective measures: one is physical isolation nets, which isolate mosquitoes by installing nets outside the windows; the other is chemical mosquito repellents, which repel mosquitoes by spraying drugs. However, both methods have obvious defects: physical isolation nets can easily affect the vision of visual machines, especially when driving at high speeds, which can easily cause window obstruction; and chemical mosquito repellents are not only harmful to the environment, but also cause equipment corrosion and increase maintenance costs if used for a long time.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The purpose of the present invention is to provide a non-powered window pneumatic mosquito-proof structure based on the principle of fluid mechanics. By utilizing the natural airflow generated when the vehicle is running, a stable protective barrier can be formed without additional power to prevent pollutants from attaching, and the windows of visual machines can be effectively protected from pollution.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 5As shown, this embodiment provides a non-powered window pneumatic mosquito-proof structure based on the principle of fluid mechanics, which is suitable for being installed on an intelligent visual machine on the top of a locomotive, and includes: a window protective cover structure 1 and a guide structure 2. The window protective cover structure 1 is used to place the visual machine of the railway locomotive. The window protective cover structure 1 is connected to the guide structure 2. The guide structure 2 is provided with an air inlet 3. The window protective cover structure 1 is provided with an air outlet 4. Air enters the guide structure 2 and the window protective cover structure 1 in sequence from the air inlet 3, forming a uniform airflow barrier on the window surface of the visual machine, and flows out from the air outlet 4. This embodiment uses the airflow generated when the vehicle is running to form a stable airflow barrier on the surface of the visual machine, thereby effectively preventing pollutants such as mosquitoes and dust from affecting the imaging quality.

[0029] Specifically, in this embodiment, the guide housing and the window protection cover structure 1 are detachably connected by bolts. The guide housing is provided with a first interface, and the window protection cover structure 1 is provided with a second interface. The first interface and the second interface are located in corresponding positions and are connected. A guide channel is provided in the guide housing for converging and accelerating airflow to ensure that the strength of the airflow barrier is sufficient to repel mosquitoes.

[0030] In this embodiment, the guide structure 2 adopts a modular connection method, which is convenient for adjustment and optimization under different vehicle models and environmental conditions. This modular design not only improves adaptability, but also facilitates installation, disassembly and maintenance. The various parts are closely combined to form an integrated structure to ensure the stability of the airflow barrier. The guide structure 2 includes a guide housing, which adopts an inverted cone structure, and its lower end is smaller than the upper end, so as to reduce air resistance when driving at high speed. During the high-speed driving of the vehicle, the air resistance can be reduced; the front side of the guide housing is provided with a guide plate 5, and one end of the guide plate 5 is hinged to the guide housing through an elastic hinge, that is, flexibly connected, and the guide plate 5 and the guide housing form an air inlet 3. The elastic hinge not only plays the role of a hinge connection, but also has an elastic function, which can automatically adjust the angle of the guide plate 5 when the airflow pressure changes. When the vehicle is stopped, under the action of the elastic hinge, the guide plate 5 closes the air inlet 3, and as the vehicle speed changes, the angle of the guide plate 5 changes, thereby changing the size of the air inlet 3. The guide plate 5 of this embodiment is used to adjust the airflow path and further enhance the stability of the airflow barrier. The guide plate 5 automatically changes its angle as the air flow pressure changes, thereby changing the size of the air inlet 3 to ensure that the air flow evenly covers the window surface to drive away mosquitoes and pollutants.

[0031] In this embodiment, two guide vanes 6 are arranged in the guide housing, and the two guide vanes 6 are arranged on the rotating shaft close to the inner walls on both sides of the guide housing, respectively. The guide vanes 6 are arranged parallel to or at a certain angle to the inner walls on both sides of the guide housing, and the guide vanes 6 and the guide housing can rotate relative to each other. In the case of a high-speed vehicle, the setting of the guide vanes 6 can make the air form a rotating airflow through the guide vanes 6, that is, form an air vortex, which can increase the energy and adhesion of the airflow, play a role in guiding and pressurizing the air, and thus enhance the effect of the airflow barrier.

[0032] In this embodiment, the front end of the window shield structure 1 (in the same direction as the front end of the vehicle) protrudes from the visual machine, and the front end of the window shield structure 1 is provided with an opening, and the rear end of the window shield structure 1 is provided with an air outlet 4, and the gap between the side of the visual machine and the inner wall of the window shield structure 1 is controlled to be between 0.5 and 2 mm. The air enters the guide channel through the air inlet 3 and can flow in a spiral, enter the window shield structure 1 through the first interface and the second interface, flow to the front end of the window shield structure 1 and the surface of the visual machine, form an airflow barrier between the front end of the window shield structure 1 and the surface of the visual machine, and then pass through the gap between the side of the visual machine and the inner wall of the window shield structure 1, and flow out from the air outlet 4.

[0033] In this embodiment, the window protection cover structure 1 plays the role of fixing the guide structure 2 and protecting the visual machine, ensuring the stability of the entire structure. The window protection cover structure 1 adopts a modular design, which is easy to install and maintain. The outer surface of the window protection cover structure 1 is provided with a waterproof sealing layer to prevent rainwater from penetrating. The inner surface of the window protection cover structure 1 is provided with a film heating element, which is preferably a flexible film type electric heater, to prevent the visual machine window from frosting and fogging in cold weather and maintain the clarity of the visual machine window.

[0034] Based on the principle of fluid mechanics, this embodiment can use airflow to naturally form an airflow barrier when the vehicle is traveling at high speed to prevent mosquitoes and pollutants from attaching to the window of the visual machine, thereby improving image clarity and recognition accuracy. The guide plate 5 and the guide impeller 6 can accelerate the airflow, so that the airflow flows along the surface of the visual machine window, forming a continuous airflow barrier, effectively covering the window area.

[0035] At low speeds (0–30 km / h):

[0036] When the vehicle is traveling at a low speed and the air flow pressure is low, the air flow velocity in the guide channel is insufficient to generate a strong rotating air flow, thereby reducing the rotation of the blades of the guide impeller 6 and allowing the air flow to pass through the guide channel more directly; the guide plate 5 at the bottom of the guide shell will maintain a smaller angle and gap, that is, a smaller air inlet 3, to concentrate the limited air flow so that it can effectively cover the window area and form a stable but not strong air barrier.

[0037] When driving at high speed (over 60 km / h):

[0038] When the vehicle speed increases and the airflow pressure increases, the blades of the guide impeller 6 are pushed by the airflow to produce a rotating airflow effect, so that the airflow fits the window surface more closely, achieving a continuous clean barrier to block mosquitoes and pollutants. The guide plate 5 at the bottom of the guide shell will automatically adjust to a larger gap, that is, a larger air inlet 3 under high airflow pressure to disperse the strong airflow, maintain the uniformity of the airflow barrier, and prevent turbulence caused by airflow concentration.

[0039] The non-powered window pneumatic mosquito-proof structure based on the principle of fluid mechanics of this embodiment adopts a passive adjustment mechanism, and uses the airflow pressure change generated by the vehicle to change the rotation speed of the guide vane 6 and the angle of the guide plate 5, so as to adjust the strength and range of the airflow barrier at different speeds, and ensure that the best airflow barrier can be formed under different speeds and airflow conditions, without the need for an external power source, and achieve the purpose of non-powered mosquito repellent. By effectively preventing the adhesion of mosquitoes and dust on the window surface, the lens of the intelligent visual machine is ensured to be clean, and the clarity of the image and the recognition accuracy of the system are significantly improved, especially in high-speed driving and night environments. Since the structure realizes automatic protection through airflow, no additional maintenance and cleaning frequency is required, the downtime maintenance time caused by window pollution is reduced, and the service life of the equipment is extended. Compared with traditional chemical mosquito repellent measures, the pure physical mosquito repellent design of the present invention is not only environmentally friendly and pollution-free, but also avoids the problem of chemical corrosion of equipment, has a high environmental value, ensures the long-term stable operation of the equipment, and the structure avoids additional maintenance requirements through automatic airflow protection, and significantly reduces the downtime frequency caused by window pollution.

The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
