The following is further detailed by way of specific embodiments:
as shown in fig. 1 to fig. 3, a nozzle for cleaning a camera commonly used by water and gas comprises a camera 11 and a nozzle, the nozzle is installed on one side of the camera 11, a protective mirror 12 is arranged on the surface of the camera 11, the nozzle comprises a nozzle base body 21 and a connecting pipeline 22, the nozzle base body 21 is fixedly connected and communicated with the connecting pipeline 22, a water outlet 23 is arranged at one end of the nozzle base body 21, an accelerating channel 27 is arranged in the nozzle base body 21 and is communicated with the water outlet 23, the accelerating channel 27 is connected with a water inlet channel 25 in the connecting pipeline, an upper guide wall 31 is arranged on the top side of the accelerating channel 27 and is a lower guide wall 32 arranged on the bottom side of the accelerating channel 27, the upper guide wall 31 and the lower guide wall 32 are distributed at an acute angle, the accelerating channel 27 is gradually narrowed from one end of the accelerating channel away from the water outlet 23 to one end of the channel close to the water outlet 23, the upper guide wall 31 is connected with the water outlet 23 through an upper diffusion wall 33, the lower guide wall 32 is connected with the water outlet 23 through a lower diffusion wall 34, and the upper guide wall 31 and the lower guide wall 32 are both arc-shaped, so that the upper guide wall 31 and the water outlet 23 smoothly transition, and the lower guide wall 32 and the water outlet 23 smoothly transition.
The nozzle is tightly attached to the edge of the camera 11, the shape of the nozzle base body 21 is outside the visual field range of the camera 11 (as shown in fig. 1 and fig. 2), the water outlet 23 is aligned with the protective mirror 12 of the camera 11, fluid such as water, gas and the like enters the acceleration channel 27 inside the nozzle base body 21 from the water inlet channel 25 of the connecting pipeline 22, the upper guide wall 31, the lower guide wall 32, the upper diffusion wall 33 and the lower diffusion wall 34 of the acceleration channel 27 constantly accelerate and rectify the fluid entering the acceleration channel and flow to the water outlet 23, and the fluid flows through the water outlet 23 and is then uniformly sprayed on the protective mirror 12 of the camera 11 to impact-clean the protective mirror 12.
As shown in fig. 4, the connection portions between the upper diffuser wall 33, the lower diffuser wall 34, and the water outlet 23 are formed in an arc shape, and the ratio of the width to the length of the arc is a: B =1:5 or more.
Wherein, the connection part of the two diffusion walls and the water outlet 23 is arc-shaped, and the width-length ratio A: B of the arc is more than 1:5 so that the fluid accelerated by the acceleration channel 27 does not lose pressure and velocity.
As shown in fig. 2, a reserve chamber 26 is provided in the nozzle base body 21, and the acceleration passage 27 is connected to the water supply passage 25 through the reserve chamber 26.
The jet flow channel is completely arranged in the nozzle base body 21, and the complete jet flow channel consists of a water inlet channel 25, a storage chamber 26, an acceleration channel 27 and a water outlet 23. After the fluid enters the water inlet channel 25 and is then delivered to the reserve chamber 26, the fluid speed in the reserve chamber 26 will be slowed down, the fluid pressure will increase, and the increased pressure will serve as a power reserve to provide power for the fluid to accelerate at a later stage. The reserve chamber 26 is also a transition passage connecting the water inlet passage 25 and the acceleration passage 27; the accelerating channel 27 is distributed between the reserve chamber 26 and the water outlet 23, the shape of the accelerating channel 27 gradually narrows from the reserve chamber 26 side to the water outlet 23 side, as shown in fig. 2, a certain acute angle is formed between a guide wall 31 on the accelerating channel 27 and the lower bottom wall of the accelerating channel 27, so that the pressure of the fluid in the reserve chamber 26 is continuously released, and after passing through the accelerating channel 27 which is wide at the front and narrow at the back, the speed of the fluid is maximally accelerated, thereby providing a source for efficient impact at the later stage; the upper diffusion wall 33 and the lower diffusion wall 34 at the end of the acceleration channel 27 smoothly transition to the upper wall 43 and the lower wall 44 of the water outlet 23 in an arc shape, so that the fluid from the upper diffusion wall 33 and the lower diffusion wall 34 collides with each other at the water inlet end of the water outlet 23, the direction of the fluid after collision is changed, and most of the fluid flows out along the direction parallel to the water outlet 23 to form a fan-shaped spray shape.
As shown in fig. 4, the side walls of the two sides of the water outlet 23 are respectively a first side wall 41 and a second side wall 42, and the included angle between the first side wall 41 and the second side wall 42 is between 10 ° and 70 °.
As shown in fig. 2, the side walls on the upper and lower sides of the water outlet 23 are an upper wall 43 and a lower wall 44, the distance between the upper wall 43 and the lower wall 44 is less than 1 mm, the minimum surface distance between the first side wall and the second side wall is L, the minimum surface distance between the upper wall and the lower wall is H, and L: H =5:1 or more.
As shown in fig. 4, the tail end of the acceleration channel 27 is connected to the water outlet 23, the first side wall 41 and the second side wall 42 of the water outlet 23 are arranged at a diffusion included angle, the water outlet 23 is shaped like a flat long arc, the fluid sprayed from the water outlet 23 is diffused in a fan shape, after the fluid at two ends of the fluid beyond the diffusion included angle impacts the first side wall 41 and the second side wall 42, the direction of the fluid is changed, and the changed direction is ejected along the diffusion included angle between the two side walls. The arrangement of the two side walls enables fluid sprayed by the nozzles to cover and clean the mirror surface of the camera 11 to the maximum extent, incomplete covering of the mirror surface of the camera 11 due to too small included angle and waste of fluid at two ends of the fan shape due to too large included angle are avoided, and impact force is reduced; the setting positions and the distance parameters of the first side wall 41, the second side wall 42, the upper wall 43 and the lower wall 44 enable the shape of the water outlet 23 to be long and flat, so that the water outlet 23 can spray the impact surface of fluid in a linear shape, the jet flow can spray the protective mirror surface 12 of the camera 11 in the maximum amplitude, and in the actual test, the linear compressed air jet flow has better jet effect and smaller energy loss.
The width between the upper wall 43 and the lower wall 44 of the water outlet 23 is set within 1.0mm, and the extremely narrow passage can better accelerate the fluid in the water outlet 23 again, and can give the highest speed to the fluid in the final passage, so that the maximum impact force is generated.
Because delivery port 23 is pressed close to camera 11 mirror surface to the utmost, the distance that reaches camera 11 mirror surface through delivery port 23 is short, and the distance that the fluid flies in the space is short, has reduced fluidic resistance to reduce the loss, when the nozzle is gas injection, because gas density is little, inertia is little, and compressible, and energy capacity dissipates, and is better to the effect that reduces the loss.
Although the liquid has large inertia force, is incompressible, has small inertia force of gas, is compressible and can easily dissipate energy, the flow channel design of the nozzle can simultaneously meet the requirements of single water injection, single gas injection and water-gas mixed injection, the diffusion distribution characteristics of the injection are basically similar, the diffusion included angle ranges are basically similar, and the high-efficiency impact performance is also kept.
As shown in fig. 2, the other end of the nozzle base 21 is provided with a sealing member 24.
As shown in fig. 5 and 6, the method for manufacturing the water-air shared camera cleaning nozzle specifically includes:
s1, the nozzle, a connecting pipeline 22, a water outlet 23, an accelerating channel 27, a storage chamber 26 and a water inlet pipeline are integrally formed in an injection molding mode, a sealing installation opening is formed in the end portion, far away from the water outlet 23, of the nozzle in an injection molding mode, and a sealing piece 24 is manufactured independently;
s2, installing the sealing element 24 into the sealing installation opening, and enabling the sealing element 24 to be fixedly connected or in interference fit with the sealing installation opening.
As shown in fig. 5 and 6, the nozzle cannot be integrally injection molded due to the design shape of the inner space of the nozzle. The side of the nozzle reserve chamber 26 remote from the acceleration channel 27 is hollowed out to form a seal mounting opening, the seal mounting opening enables the internal structure of the nozzle base body 21 and the connecting pipeline 22 to be integrally injection-molded, and then the area of the seal mounting opening is blocked by the sealing piece 24, so that the internal space of the nozzle base body 21 forms a complete closed nozzle flow channel.
As shown in fig. 5 and 6, the mounting method of the sealing member 24 is roughly divided into 2 types, 1 type is to provide a sealing mounting opening with a spherical shape or other shapes, to integrally injection mold the nozzle base body 21 and the internal space thereof, to press-fit the sealing member 24 at the sealing mounting opening, the shape of the sealing member 24 is adapted to the sealing mounting opening, and the sealing member 24 includes but is not limited to materials such as metal, plastics, and the like. The other 1 is to provide a seal mounting opening, so that the main body of the nozzle is integrally injection-molded, and the sealing element 24 is mounted in the seal mounting opening in a welding or interference fit manner. Both of these means simply and effectively close the inner space of the nozzle base body 21. The above 2 assembling processes are characterized in that the position of the sealing opening of the nozzle reserve chamber 26 according to the shape is an unimportant position of the flow channel, the assembling deviation of the position does not affect the injection stability of the nozzle, the nozzle base body 21 is integrally injection-molded, the precision of the whole flow channel can be well controlled by using the injection precision, and the injection effect and the state can be stabilized.
The specific implementation process is as follows:
when the water-gas shared camera is used for cleaning the nozzle, firstly, a gas source and a liquid source are introduced into the connecting pipeline 22; when the protective mirror surface 12 of the camera 11 needs to be cleaned, the air source and the liquid source are conducted to the water inlet channel 25 in the connecting pipeline 22, then the liquid enters the storage chamber 26 to be pressurized, the pressurized liquid enters the acceleration channel 27 to be accelerated by the acceleration channel 27 and then is conducted to the water outlet 23, and the water blowing port diffuses the liquid in a fan shape and sprays the liquid to the protective mirror surface 12 of the camera 11 to clean the protective mirror surface 12 of the camera 11; then, the liquid source is closed, and the gas source is conducted, so that the water outlet 23 sprays gas, and the protection mirror surface 12 of the camera 11 is dried; due to the action of the storage chamber 26 and the accelerating channel 27 in the nozzle base body 21, the air source and the liquid source can be started simultaneously, liquid and gas can be simultaneously input into the nozzle to clean the camera 11, the loss of the injection pressure of the gas and the liquid can not be caused, and the problem that the protective mirror surface 12 cannot be cleaned cleanly can not occur.
This camera washing nozzle is shared to aqueous vapor is through inputing cleaning solution or gas or the combination of both in the inhalant canal 25 from connecting tube 22 for aqueous vapor gets into to accelerateing behind the passageway 27 and is sprayed by delivery port 23 with fan-shaped diffusion and wash camera 11's protective mirror surface 12, and then high-efficient ground protective mirror surface 12 washes away the washing, and weathers the operation to protective mirror surface 12, avoids remaining drop of water to influence camera 11's work.
