[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1 to 3 The windshield drainage system assembly of an automobile in this embodiment includes a deflector plate 1, a water collection trough 2 fixedly connected to the left side of the deflector plate 1, a mesh frame 3 fixedly connected to the inner side of the opening of the water collection trough 2, and a filter screen 4 fixedly connected to the inner side of the mesh frame 3. The inner side of the water collection trough 2 is provided with an anti-clogging component to prevent the filter screen 4 from being blocked.
[0023] Please see Figure 1 In this embodiment, the anti-clogging component includes a support plate 5 fixedly connected between the front and rear side walls of the water accumulation tank 2, a connecting rod 6 rotatably connected to the top of the support plate 5, a water wheel 7 fixedly connected to the outside of the connecting rod 6, and a scraper 8 provided at the top of the connecting rod 6.
[0024] Specifically, the sidewall of the water collection tank 2 is sloped, and the top of the connecting rod 6 passes through the bottom and top of the mesh frame 3 in sequence.
[0025] Specifically, the top end of the connecting rod 6 is provided with a threaded groove, and the inner side of the threaded groove is threadedly connected to a threaded shaft 9, the top end of the threaded shaft 9 being fixedly connected to the scraper 8.
[0026] It should be noted that this detachable connection method facilitates the installation, disassembly and replacement of the scraper 8. When the scraper 8 is worn or damaged due to long-term use, a new scraper 8 can be easily replaced simply by unscrewing the threaded shaft 9 out of the threaded groove, which improves the convenience of equipment maintenance and service life.
[0027] Specifically, a first drain hole is provided on the front side of the inside of the water collection tank 2, and several serrations 10 are fixedly connected to the inner wall of the first drain hole. A second drain hole is provided at the bottom inside the water collection tank 2.
[0028] It should be noted that the first drainage hole is used to drain water when the water reaches a certain amount. The serration 10 can disrupt the continuity of the ice layer in winter and retain drainage microchannels. The second drainage hole can be used as a backup drainage channel.
[0029] Specifically, the inner left and right side walls of the water collection tank 2 are fixedly connected with fixing plates 11, the bottom of the fixing plates 11 is slidably connected with sliding rods 12, the outer side of the sliding rods 12 is slidably connected with mounting plates 13, the bottom of the mounting plates 13 is fixedly connected with floats 14 and sealing plugs 15, and the bottom of the sealing plugs 15 is located inside the second drain hole.
[0030] It should be noted that this structure utilizes the buoyancy principle of the float 14. When the water level in the water tank 2 changes, the float 14 will drive the mounting plate 13 to slide up and down along the slide rod 12, thereby driving the sealing plug 15 to move and control the opening and closing of the second drain hole.
[0031] Specifically, the left and right sides of the inner side of the mounting plate 13 are provided with sliding holes that are compatible with the slide rods 12, and the two slide rods 12 are slidably connected to the inner side of the corresponding sliding holes.
[0032] It should be noted that this design ensures that the mounting plate 13 can slide stably up and down along the slide bar 12, so that the float 14 can accurately sense changes in water level and convert these changes into vertical displacement of the mounting plate 13, thereby driving the sealing plug 15 to accurately open or close the second drain hole.
[0033] Specifically, the bottom end of the left slide bar 12 bends to the left and is fixedly connected to the inner left side wall of the water collection tank 2, and the bottom end of the right slide bar 12 bends to the right and is fixedly connected to the inner right side wall of the water collection tank 2.
[0034] It should be noted that this fixing method enhances the stability of the slide bar 12, preventing the slide bar 12 from shaking or shifting during the up-and-down sliding of the mounting plate 13, ensuring the normal operation of the entire drainage control device, and avoiding the instability of the slide bar 12 causing the sealing plug 15 to be unable to accurately control the opening and closing of the second drainage hole.
[0035] Specifically, there are two floats 14, and the two floats 14 are located on the left and right sides of the sealing plug 15, respectively.
[0036] It should be noted that the two floats 14 can sense water level changes more evenly, improve the sensitivity to water level changes, and enable the mounting plate 13 to slide more smoothly along the slide bar 12, thereby ensuring the accuracy of the sealing plug 15 in controlling the opening and closing of the second drain hole.
[0037] The working principle of the above embodiments is as follows:
[0038] Rainwater flows into the deflector 1 through the windshield and enters the water collection tank 2 under the guidance of the deflector 1. The water flows through the mesh frame 3 and the filter screen 4 to intercept large particles of impurities such as leaves and mud. Finally, the water flows out through the first drain hole and enters the vehicle body's drainage pipe.
[0039] To prevent the filter screen 4 from clogging, the water flow impacts the water wheel 7, causing the connecting rod 6 to rotate. The scraper 8 at the top of the connecting rod rotates accordingly and scrapes the filter screen 4 to prevent impurities from accumulating and clogging. The scraper is fixedly connected to the connecting rod 6 via a threaded shaft 9 and can be replaced after wear.
[0040] The serrations 10 on the inner side of the first drain hole can disrupt the surface tension of the water flow, reduce the adhesion of impurities, and when the water freezes in winter, the serrations 10 can delay the complete closure of the drain hole by the ice layer, maintaining some drainage capacity. When the first drain hole cannot be used due to blockage or other reasons, the second drain hole comes into play. When the water level in the water tank 2 rises, the float 14 floats up due to buoyancy. The float 14 drives the mounting plate 13 to slide vertically along the slide rod 12, which in turn drives the sealing plug 15 to rise and open the second drain hole.
[0041] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
[0042] It should be noted that the orientations or positional relationships indicated herein are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of facilitating the description of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
