Description

Technical Field

[0001] The invention relates to the technical field of lens protection, and in particular to an open optical path lens protection system. Background Art

[0002] According to feedback from engineering operation and maintenance, the external protective mirrors in the optical path of the optical inspection equipment are often seriously contaminated by sprinkler trucks. The pollutants are a mixture of mud and water caused by sprinkler trucks. Because the frequency of the impact of sprinkler trucks is too high, the protective mirrors need to be maintained frequently, which requires a lot of manpower, and repeated wiping and cleaning can easily cause scratches on the lenses, affecting the measurement accuracy of the equipment. Summary of the invention

[0003] The object of the present invention is to provide an open optical path lens protection system to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] An open optical path lens protection system comprises a main window plate, a lens groove is provided on the main window plate, a main window plate lens is arranged in the lens groove, and a waterproof cover is movably connected to the lens groove;

[0006] An upper hinge fixing plate is fixedly arranged on one side of the lens groove, a motor is arranged in the upper hinge fixing plate, a gear is fixedly connected to the motor output shaft, an upper hinge is arranged on one side of the gear, one end of the upper hinge is meshed with the gear and the other end is fixedly connected to the waterproof cover, an electromagnet is fixedly arranged under the gear, and the electromagnet is movably connected to the upper hinge;

[0007] A raindrop sensor fixing plate is arranged on one side of the main window plate, and a plurality of raindrop sensors are installed on the raindrop sensor fixing plate.

[0008] Preferably, a raindrop sensor base is arranged below the raindrop sensor fixing plate, a raindrop sensor protective cover is arranged above the raindrop sensor base, the raindrop sensor protective cover is fixedly connected to the raindrop sensor fixing plate, raindrop sensor support frames are fixedly arranged on both sides of the raindrop sensor protective cover, an installation groove is opened in the raindrop sensor, a raindrop sensor rotating rod is inserted into the installation groove, and the raindrop sensor rotating rod is fixedly connected to the raindrop sensor fixing plate.

[0009] Preferably, a lower hinge fixing plate is fixedly arranged below the upper hinge fixing plate, a lower hinge is rotatably arranged in the lower hinge fixing plate, and the lower hinge is fixedly connected to the waterproof cover.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The lens protection system of the present invention has a waterproof cover in an open state under normal working conditions, and the hinge is attracted by an electromagnet to fix the waterproof cover. When a watering truck passes by, water droplets will splash onto the raindrop sensor, and the electromagnet is powered off through program control. After the electromagnet is powered off, it is demagnetized, and the waterproof cover is rotated through the gears and hinges to cover the lens on the main window panel. When the watering truck moves away, the waterproof cover is opened through the transmission between the gears and the hinges to restore it to its original position.

[0012] The present invention uses the monitoring function of the raindrop sensor. When raindrops are detected by the sensor, the sensor controls the electromagnet to cut off power and demagnetize, so that the waterproof cover rotates to cover the main window plate lens. After no raindrop signals are detected for a period of time, the sensor outputs a signal to control the motor to rotate, so that the gear can drive the upper hinge to rotate, thereby opening the waterproof cover and no longer covering the main window plate lens, which can greatly reduce the workload and maintenance costs of engineering operation and maintenance personnel.

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-8 , the present invention provides a technical solution:

[0024] An open optical path lens protection system comprises a main window plate 1, a lens groove 2 is provided on the main window plate 1, a main window plate lens 3 is arranged in the lens groove 2, the main window plate lens 3 is arranged in the lens groove 2, parameters of the main window plate lens 3 are selected according to actual needs, so that different types of main window plate lenses 3 can be installed in the lens groove 2, and a waterproof cover 4 is movably connected at the lens groove 2, and the waterproof cover 4 is movably arranged at the lens groove 2, and the waterproof cover 4 can be closed to completely cover the lens groove 2, and the waterproof cover 4 can also be unfolded to one side to completely show the main window plate lens 3 in the lens groove 2 for use.

[0025] An upper hinge fixing plate 5 is fixedly arranged on one side of the lens groove 2. The interior of the upper hinge fixing plate 5 is arranged as a hollow structure. A motor 6 is arranged in the upper hinge fixing plate 5. The motor 6 is fixed in the hollow structure of the upper hinge fixing plate 5, and the output shaft of the motor 6 is arranged downward. The output shaft of the motor 6 is fixedly connected with a gear 7, which can be driven to rotate synchronously by starting the motor 6. An upper hinge 8 is arranged on one side of the gear 7. The upper hinge 8 structure is divided into two parts. One end of the upper hinge 8 is meshed with the gear 7 and the other end is fixedly connected to the waterproof cover 4. One part One part is used for meshing gear 7, so that gear 7 can drive upper hinge 8 to rotate synchronously during rotation, and the other part is used for fixing with waterproof cover 4. Only when it is fixed with waterproof cover 4, can waterproof cover 4 be driven to rotate when upper hinge 8 rotates, so that waterproof cover 4 can achieve the purpose of closing lens slot 2 and showing lens slot 2. Electromagnet 9 is fixedly arranged under gear 7, and electromagnet 9 is electrically connected with external controller. By externally controlling the power on and off of electromagnet 9, whether electromagnet 9 has magnetic adsorption force is controlled. The electromagnet 9 is movably connected to the upper hinge 8. When the waterproof cover 4 is opened and does not cover the lens groove 2, the electromagnet 9 has a magnetic adsorption force, which adsorbs one end of the upper hinge 8, so that the waterproof cover 4 is adsorbed and fixed, so that the main window plate lens 3 cannot be blocked. When the raindrop sensor 16 detects a water drop signal, the signal is transmitted to an external controller system, such as a PLC controller or a single-chip microcomputer. After receiving the signal, the controller or the single-chip microcomputer performs data processing, thereby further controlling the electromagnet 9 to be powered off, so that the electromagnet 9 no longer has a magnetic adsorption force, so that the upper hinge 8 drives the waterproof cover 4 to rotate, and the main window plate lens 3 in the lens groove 2 is completely covered to prevent the main window plate lens 3 from being contaminated by water. After the water drop signal disappears, the raindrop sensor 16 transmits the signal to the external controller system, and the controller controls the motor 6 to rotate. At the same time, the electromagnet 9 is powered on and has a magnetic adsorption force. When the motor 6 drives the gear 7 to rotate, it synchronously drives the upper hinge 8 to rotate, thereby driving the waterproof cover 4 to open, and once again showing the main window plate lens 3 in the lens groove 2 without blocking it.

[0026] A raindrop sensor fixing plate 15 is provided on one side of the main window panel 1. The raindrop sensor fixing plate 15 can be fixedly connected to the side wall of one side of the main window panel 1, which is convenient for the installation and portable use of the system device. A plurality of raindrop sensors 16 are installed on the raindrop sensor fixing plate 15. The raindrop sensors 16 are used to detect water drop signals generated by a sprinkler truck or other equipment. When the raindrop sensor 16 detects water droplets, it generates a signal and transmits it to an external controller. The controller controls the on / off or forward / reverse rotation of the motor 6 or the electromagnet 9 through an application program. The program application and the model selection of the motor 6 and the electromagnet 9 are very simple. It can be achieved by selecting conventional technology and actual parameters, and the general driving speed of a sprinkler truck is below 20km / h, the conversion unit is 5.5m / s, the automatic door stroke length required by the protective lens is 200mm, the running speed of motor 6 is designed to be 400mm / s, and the signal delay and the response time of motor 6 are taken into account. It is known that the maximum time required to close the door is 2 seconds, and the wire length of the raindrop sensor 16 needs to be 10m. Taking the shielding area required by the main window panel lens 3 as 200mm*260mm as an example, only 0.5mm thick aluminum alloy plate is required as the protective door material, and the mass is 200g.

[0027] In order to facilitate the installation of the raindrop sensor 16 and the use in conjunction with the main window panel 1, a raindrop sensor base 10 is provided below the raindrop sensor fixing plate 15, and a raindrop sensor protective cover 11 is provided above the raindrop sensor base 10. The raindrop sensor protective cover 11 is used to protect the raindrop sensor 16 to prevent small raindrops from affecting the raindrop sensor 16, so that the raindrop sensor 16 will only be provided with a detection signal when a sprinkler truck passes by and provides a large amount of raindrops. The raindrop sensor protective cover 11 is fixed to the raindrop sensor fixing plate 15. The raindrop sensor 16 is connected so that the raindrop sensor shield 11 just completely covers the raindrop sensor 16 on the fixing plate 15. Raindrop sensor support frames 12 are fixedly arranged on both sides of the raindrop sensor shield 11. A mounting groove 13 is opened in the raindrop sensor 16. A raindrop sensor rotating rod 14 is inserted in the mounting groove 13. The raindrop sensor rotating rod 14 is fixedly connected to the raindrop sensor fixing plate 15. The raindrop sensor support frame 12 and the raindrop sensor fixing plate 15 are fixed to each other by opening the raindrop sensor rotating rod 14 and the mounting groove 13.

[0028] As a preferred embodiment, a lower hinge fixing plate 17 is fixedly provided below the upper hinge fixing plate 5, and a lower hinge 18 is rotatably provided in the lower hinge fixing plate 17. The lower hinge 18 is fixedly connected to the waterproof cover 4. The lower hinge 18 can rotate around the lower hinge fixing plate 17, thereby driving the waterproof cover 4 to rotate, driving the waterproof cover 4 to cover and open the lens groove 2, and playing an auxiliary supporting role for the upper hinge fixing plate 5 and the upper hinge 8, so that the rotation process of the waterproof cover 4 is more stable.
