Description

Technical Field

[0001] The invention belongs to the field of jet cleaning, and in particular relates to a concealed side-cut fan-shaped nozzle. Background Art

[0002] Integrated optoelectronic equipment usually contains multiple lenses and sensors. The surfaces of the lenses and sensors need to be kept clean during operation, otherwise it will affect the detection accuracy and may form local hot spots that damage the equipment. During long-term use, the surfaces of external sensors and lenses will inevitably be contaminated by pollutants such as dirt, dust, flying insects, rain and snow, and need to be cleaned by jet nozzles. Sensors come in a variety of types, with different sizes, shapes, installation locations, and cleaning requirements. The cleaning nozzle cannot block the sensor's detection field of view, and has extremely high requirements for the nozzle's volume, concealment, spray angle, and cleaning range. The market is currently in a state of customized research and development, with no mature serialized nozzles. The jet shape depends on the opening shape, resulting in poor pressurization and high flow consumption. Summary of the invention

[0003] The main purpose of the present invention is to solve the cleaning problem of integrated optoelectronic equipment and to propose a concealed side-cut fan-shaped nozzle, which can adjust parameters according to different surfaces to be cleaned to form a series of products.

[0004] The technical solution adopted by the present invention is: a concealed side-cut fan-shaped nozzle, comprising a jet outlet, a mounting interface, a pipeline interface and an inner flow channel, wherein the mounting interface is used for matching and mounting the concealed side-cut fan-shaped nozzle with the nozzle mounting surface, and the pipeline interface is used for mounting the concealed side-cut fan-shaped nozzle with the pipeline;

[0005] The jet outlet is a V-shaped incision processed on the side of the inner flow channel. By adjusting the incision center distance, incision bottom distance, incision angle, and incision pointing angle, the direction, fan angle, and flow rate of the jet can be changed.

[0006] Compared with the existing notch-type fan-shaped nozzle, the present invention has the following beneficial effects: the nozzle is small in size, installed sideways, and highly concealed; the spray direction can be adjusted arbitrarily; and multiple notches can be designed to clean targets at different positions.

[0012] In order to make the purpose and technical solution of the present invention more clear, the detection principle of the present invention is further described in detail below in conjunction with the embodiments.

[0013] First, combine with Figure 1 , 2 The structure of the concealed side-cut fan-shaped nozzle is further described. The concealed side-cut fan-shaped nozzle comprises a jet outlet 1, a mounting interface 2, a pipeline interface 3 and an inner flow channel 4. The end of the inner flow channel 4 is connected to the pipeline interface 3, the mounting interface 2 is sleeved on the outer side of the inner flow channel 4, the mounting interface 2 is used for matching the concealed side-cut fan-shaped nozzle with the nozzle mounting surface, and the pipeline interface 3 is used for installing the concealed side-cut fan-shaped nozzle with the pipeline.

[0014] The jet outlet 1 is a V-shaped cutout processed on the side of the inner flow channel 4. The direction, fan angle and flow rate of the jet can be changed by adjusting the cutout center distance d, the cutout bottom distance s, the cutout angle α and the cutout pointing angle θ. Figure 2 The cut center distance d refers to the distance from the apex of the V-shaped cut to the axis of the inner flow channel, the cut bottom distance s refers to the distance from the apex of the V-shaped cut to the apex of the inner flow channel, the cut angle α refers to the opening angle of the V-shaped cut, and the cut pointing angle θ refers to the angle between the top edge of the V-shaped cut and the axis of the inner flow channel.

[0015] The V-shaped incision is a narrow V-shaped incision, and its specific width and narrowness range can be determined by those skilled in the art according to actual needs. The V-shaped incision is used to produce a flat fan-shaped jet with a good pressurization effect. The jet range that the incision can produce is as follows: Figure 3 shown.

[0016] In one embodiment, a plurality of jet outlets 1 may be designed on the concealed side-cut fan-shaped nozzle to clean targets at different positions. The design of the plurality of jet outlets 1 is as follows: Figure 4 shown.

[0017] The inner flow channel 4 is a cylindrical flow channel with a fixed cross-section or a cylindrical flow channel with a variable cross-section. A cross-section contraction section can be added to further increase the pressure. The cross-section contraction section refers to an inner flow channel with a changing inner diameter. The specific setting method is to divide the inner flow channel into two sections. The diameter of the inlet section is larger than that of the outlet section, and the two sections of the flow channel are transitioned through an inclined surface or an arc surface. The mounting interface 2 is a two-hole flange, which can also be changed to other interface forms according to the requirements of the mounting surface. The pipeline interface 3 is a pagoda head, which can be connected to a hose with a suitable inner diameter. The pipeline can be further tightened with a clamp, or it can be changed to a threaded interface and connected to other joints or pipelines with sealing materials.

[0018] The concealed side-cut fan-shaped nozzle is installed on the side of the object to be cleaned without blocking the object to be cleaned.

[0019] The fan-shaped nozzle can be processed by simple process means such as drilling, milling, and wire cutting.

[0020] In summary, the fan-shaped nozzle has the advantages of easy processing, small size, strong concealment, good pressurization effect, large cleaning area, and adjustable jet direction, fan angle and flow rate. The principle and feasibility of the invention have also been verified by experiments, and other similar principles and configurations are also considered to be within the protection scope of the present invention.
