[0002] At present, the sea-sweeping lights used in ships include light sources and electronic ballasts. When the electronic ballasts are working, electromagnetic noise interference is inevitably generated. This interference is carried out in two ways: free space radiation and power grid conduction. Its electric field and magnetic field have a serious impact on the radar and communication equipment on the ship, affecting their normal use. In addition, the brightness requirements of the sea-sweeping lights are relatively high, and they often use high-power light sources, which will cause a heat dissipation problem. If the heat dissipation performance of the sea-sweeping lights is not good, the temperature inside the sea-sweeping lights will be too high, accelerating the aging of the components; and its light source is usually not adjustable, that is, the focal length and light spot of the sea-sweeping lights cannot be adjusted, and cannot be adjusted according to the illumination requirements, so the actual use effect is poor.

[0003] In the related art, a Chinese patent with application number CN106439627A proposes a high-power sea sweeping light for ships, including a base, an electrical control box and a light source assembly, characterized in that it also includes a bracket assembly, a reflector, a focusing assembly, an adjustment component, an AC contactor, a thermal relay, a three-phase reactor, a starting capacitor, a three-phase transformer, a three-phase ballast, a filter capacitor and a trigger; the light source assembly includes a light source, a front mounting part and a rear mounting part, and a reflector is arranged in the base; the adjustment component includes a central bracket, a fixing part and an adjustment screw; the focusing assembly includes a focusing screw, a fixing bracket and a slider; the bracket assembly includes a mounting bracket and a locking structure.

In this embodiment, by setting waist-shaped grooves and reflective grooves, the continuity and regular shape of the shell can be effectively destroyed, thereby changing the radar reflection characteristics of the lamp body. This design can significantly reduce the RCS of the sea sweeping lamp, making it more difficult to be detected by enemy radars; it can also cause radar waves to scatter on the surface of the lamp body, further reducing the intensity of the radar echo.

When the fixed rod moves outside the measuring cylinder, water flows out from the side hole, and the traction motor controls the first winding roller to rotate, and the new dissolved film is pulled to the side hole position to protect the second water sensor;

[0027] 3. In the initial position, the plastic film blocks the extrusion hole. When the volume of the water tank is smaller than the volume of the reflection groove, the water in the water tank completely enters the reflection groove. The test paper does not change at this time. At this time, the third water sensor needs to be controlled to move downward. At the same time, the water-absorbing film needs to be pulled to the bottom of the third water sensor. The third water sensor drives the water-absorbing film to move into the reflection groove. The third water sensor is wrapped by the water-absorbing film until the third water sensor moves to the bottom of the opening of the reflection groove. The water-absorbing film dissolves in water. After the third water sensor recognizes water, the third water sensor is controlled by the PLC controller to be connected to the third buzzer. The third buzzer is triggered to make a sound, which proves that the volume of the reflection groove is smaller than the volume of the water tank and the reflection groove molding does not meet the standards. Only when the third water sensor just moves to the opening of the reflection groove, the third buzzer makes a sound, which proves that the reflection groove meets the standards.

RCS is a physical quantity that quantitatively characterizes the strength of target scattering. The smaller its value, the smaller the energy received by the radar, making it difficult for the enemy reconnaissance radar to make a correct judgment on its own target. In this embodiment, by providing the waist-shaped groove 6 and the reflective groove 7, the continuity and regular shape of the shell 4 can be effectively destroyed, thereby changing the radar reflection characteristics of the lamp body. This design can significantly reduce the RCS of the sea sweeping lamp, making it more difficult to be detected by enemy radars; it can also cause radar waves to scatter on the surface of the lamp body, further reducing the intensity of the radar echo.

[0042] S1. Production of shell 4: multiple waist-shaped grooves 6 and multiple reflective grooves 7 on the shell 4 are extruded by an extrusion device, and the heat dissipation holes 5 on the shell 4 are punched and formed by a punching device; finally, the shell 4 is rolled into a round shape; the punching device punches holes in the shell 4 by hydraulic punching, thereby realizing the forming of the heat dissipation holes 5, and then the waist-shaped grooves 6 and reflective grooves 7 are formed by the extrusion device, and finally the shell 4 is rolled into a round shape by a rolling machine and then welded to complete the forming of the shell 4.

[0043] S2, lamp body installation: assemble the light source 18 module 1, the optical system, and the control device and install them in the housing 4 to obtain the lamp body of the sea sweeping lamp;

[0044] S3, assembling the lamp stand: assembling the lamp body, the bracket 3 and the base 2 to obtain the sea sweeping lamp;

[0045] S4. Quality inspection: Carry out appearance inspection, electrical performance test and light output quality test on the finished sea sweeping lights to ensure that the products meet the requirements;

[0046] Reference Figure 2 and Figure 3 The extrusion device includes a workbench 8, an extrusion frame 9 which is lifted and arranged on the workbench 8, an extrusion plate 10 which is arranged on the extrusion frame 9, a plurality of extrusion blocks 11 and a molding piece 12 which is arranged on the surface of the workbench 8. The molding piece 12 is adapted to the reflection groove 7 and the waist-shaped groove 6 on the shell 4, and the reflection groove 7 has the same depth as the waist-shaped groove 6; the molding piece 12 is set as molding sand or rubber piece, and the shell 4 in a plane is placed on the workbench 8. The extrusion frame 9 realizes the vertical lifting work through the hydraulic cylinder. The extrusion plate 10 is fixed on the extrusion frame 9, and the area of ​​the extrusion plate 10 is larger than the area of ​​the shell 4. The extrusion blocks 11 are set as a plurality, and the plurality of extrusion blocks 11 correspond to the waist-shaped groove 6 and the reflection groove 7 respectively. The workbench 8 is provided with a molding groove, and the molding piece 12 is placed in the molding groove. The shell 4 is placed on the molding piece 12, and the extrusion plate 10 and the extrusion block 11 are used to lift and extrude the shell 4, and the reflection groove 7 and the waist-shaped groove 6 are formed.

[0047] Reference Figure 2 and Figure 3The extrusion device also includes a sizing mechanism for monitoring the extrusion depth of the reflective groove 7 and a detection mechanism for spot checking whether the reflective groove 7 meets the requirements. The sizing mechanism includes a fixed rod 13 fixed on the extrusion plate 10, a first water sensor 14 fixed at the bottom of the fixed rod 13, a first buzzer 15 electrically connected to the first water sensor 14, a measuring cylinder 16 fixed on the workbench 8, an oversize alarm component for indicating that the movement distance of the extrusion block 11 exceeds the set size, and an adjustment component for adjusting the liquid level position in the measuring cylinder 16. The measuring cylinder 16 is located below the fixed rod 13, and the liquid level in the measuring cylinder 16 is located on the same horizontal plane as the bottom of the reflective groove 7, and the bottom end of the fixed rod 13 and the bottom surface of the extrusion block 11 are located on the same horizontal plane. In this embodiment, the bottom end of the fixed rod 13 and the extrusion block 11 are positioned by a level 20. In this embodiment, the thickness of the extrusion block 11 is constant. When the thickness of the shell 4 changes, the size from the bottom of the extrusion block 11 to the surface of the shell 4 will also change. Therefore, in order to ensure that the depth dimensions of the reflection groove 7 and the waist-shaped groove 6 will not change, it is necessary to adjust the movement distance of the extrusion block 11 to ensure that the depths of the reflection groove 7 and the waist-shaped groove 6 will not change. When the thickness of the shell 4 changes, for example, when the thickness of the shell 4 becomes thinner, the horizontal plane where the bottom end of the reflection groove 7 is located will also decrease accordingly. When the thickness of the shell 4 becomes thicker, the horizontal plane where the bottom end of the emission groove is located will also rise accordingly. At this time, it is only necessary to adjust the depth dimension of the liquid level in the measuring cylinder 16. First, adjust the liquid level in the measuring cylinder 16 to the same horizontal plane as the upper surface of the shell 4, and then adjust the depth change value of the liquid level in the measuring cylinder 16 according to the depth dimension of the emission groove to ensure that the liquid level height in the measuring cylinder 16 is on the same horizontal plane as the reflection groove 7.

[0048] The first water sensor 14 is connected to the first buzzer 15 through the control of the PLC controller. When the fixed rod 13 moves with the extrusion plate 10, the first water sensor 14 in this embodiment is installed in the bottom installation groove of the fixed rod 13, that is, to ensure that the bottom end of the first water sensor 14 and the bottom end of the fixed rod 13 are on the same horizontal plane. When the first water sensor 14 moves into the measuring cylinder 16 and extrudes the reflection groove 7 with the extrusion block 11, if the first water sensor 14 just encounters the liquid surface in the measuring cylinder 16, the first water sensor 14 triggers the first buzzer 15 to start making a sound, which proves that the extrusion work of the reflection groove 7 is completed. Since the depth size of the reflection groove 7 is the same as that of the waist-shaped groove 6, this embodiment only illustrates the formation process of the reflection groove 7, and the monitoring of the forming process of the waist-shaped groove 6 is the same as that of the reflection groove 7. If the first buzzer 15 does not make a sound after the extrusion block 11 is extruded, it proves that the depth size of the reflection groove 7 is not enough and it needs to continue extrusion.

[0049] Reference Figure 1 and Figure 2The adjustment component includes a protective cover 17, a light source 18, a camera 19 and a level 20.

The side water inlet of the measuring cylinder 16 is equipped with a water pump. The bottom water inlet of the measuring cylinder 16 is used for waterproofing, and the water pump is used to pump water into the measuring cylinder 16. The camera 19 is fixed in the protective cover 17 and faces the measuring cylinder 16. The level 20 is opposite to the measuring cylinder 16 and is located on the same side of the measuring cylinder 16 as the camera 19. The level 20 is a laser level 20, and the vertical position of the level 20 can be adjusted. The level 20 and the camera 19 are located in different vertical directions. The sliding of the level 20 along the vertical direction is achieved by an electric push rod. When monitoring the same shell 4, the position of the level 20 remains constant. When the level 20 is adjusted to the specified position, the light source 18 and the camera 19 are turned on. The light source 18 irradiates the water in the measuring cylinder 16. At this time, the level 20 located on the other side is in the shadow formed by the measuring cylinder 16, which is convenient for the staff to observe through the camera 19. The liquid level in the measuring cylinder 16 can be adjusted to the specified position by using a water pump and a solenoid valve.

[0050] Reference Figure 2 and Figure 4The oversize alarm component includes a plurality of dissolving films 21, a traction rope 22, a second water sensor 23, and a second buzzer 24 electrically connected to the second water sensor 23. The dissolving film 21 is made of a starch plastic film 40, which is made of renewable starch as the main raw material and processed by adding some other substances. The starch plastic film 40 can be rapidly degraded and dissolved in a humid and temperature-appropriate environment (25°C and above); the second water sensor 23 is connected to the second buzzer 24 through a PLC controller. The side wall of the fixed rod 13 is provided with a side hole 25, and the side hole 25 is arranged at the maximum allowable reflection error. The position of the large value, that is, when it exceeds the position of the side hole 25, it proves that the thickness of the reflective groove 7 exceeds the error range, and the shell 4 needs to be adjusted. The side wall of the fixed rod 13 is provided with a traction assembly for traction of the traction rope 22, and the traction assembly includes a traction motor, a first winding roller 26 and a second winding roller 27. The fixed rod 13 is provided with operating chambers for installing the first winding roller 26 and the second winding roller 27 above and below the side hole 25. The two operating chambers are connected to the side hole 25. The first winding roller 26 and the second winding roller 27 rotate in the corresponding operating chambers respectively, and the two ends of the traction rope 22 The first winding roller 26 and the second winding roller 27 are fixedly connected respectively. A plurality of dissolving films 21 are evenly spaced and distributed on the traction rope 22. In this embodiment, the dissolving film 21 is ensured to be tightly attached to the outside of the operating cavity, and the area of ​​the dissolving film 21 is larger than the area of ​​the side hole 25. At this time, the dissolving film 21 can shield the side hole 25. The second water sensor 23 is installed on the bottom wall of the side hole 25. The dissolving film 21 completes the protection effect of the second water sensor 23. In the initial state, the traction motor is installed in the operating strong below, and a protective shell is installed outside the traction motor. The output end of the traction motor passes through the protective shell and is connected to the first winding roller 26 and the second winding roller 27. The winding roller 26 is coaxially fixed, and multiple dissolving films 21 are fixed on the second winding roller 27. When the fixed rod 13 moves to the liquid level and enters from the side hole 25 and contacts with the dissolving film 21, the dissolving film 21 is dissolved, and the second water sensor 23 triggers the second buzzer 24 to make a sound, which is to prove that the depth of the reflection groove 7 exceeds the maximum error allowable value, and the movement distance of the extrusion block 11 needs to be adjusted. When the fixed rod 13 moves to the outside of the measuring cylinder 16, water flows out of the side hole 25, and the traction motor controls the first winding roller 26 to rotate, and the new dissolving film 21 is pulled to the position of the side hole 25 to protect the second water sensor 23.

After the waist-shaped groove 6 and the reflective groove 7 on the shell 4 are extruded and formed, if there is a problem with the extrusion block 11, it will affect the corresponding reflective groove 7 or waist-shaped groove 6. The molding work will have problems, so the molding groove is detected. In this embodiment, the volume of the water tank 29 is just equal to the volume of the reflective groove 7 or the waist-shaped groove 6. The volume of the waist-shaped groove 6, therefore, when the water in the water tank 29 completely enters the reflecting groove 7 or the waist-shaped groove 6, it proves that the forming of the reflecting groove 7 or the waist-shaped groove 6 meets the standard. Once the water flows out or cannot be filled, it proves that there is a problem with the volume of the reflecting groove 7 and the waist-shaped groove 6. The detection frame 28 is fixed on one side of the workbench 8. In this embodiment, the shell 4 after extrusion can be moved by staff or mechanically to the position of the detection frame 28, and the water tank 29 randomly detects a certain reflecting groove 7 and waist-shaped groove 6 on the shell 4. As long as there is a problem with one reflecting groove 7 and waist-shaped groove 6, it proves that the processing of the shell 4 does not meet the standard.

[0052] The water in the water tank 29 is adapted to the reflective groove 7 or the waist-shaped groove 6. In this embodiment, the reflective groove 7 is used as an example for explanation. The detection work of the waist-shaped groove 6 is similar, only the volume of the water tank 29 is different. The bottom of the water tank 29 is set as an opening, and the water tank 29 is provided with a control component at its bottom. The control component includes a control board 47 and an electric push rod for realizing the repeated movement of the control board 47.

The lifting and lowering of the detection frame 28 on the workbench 8 is also realized by an electric push rod or a cylinder. The extrusion mechanism includes The extrusion block 37 is lifted and lowered in the water tank 29. The extrusion block 37 is located at the bottom of the water tank 29 at the initial position, and the extrusion block 37 slides and fits in the water tank 29. The lifting and lowering of the extrusion block 37 is also achieved by an electric push rod or a cylinder, which lowers the water tank 29 to fit the surface of the shell 4 and ensures that the water tank 29 is located directly above the reflection groove 7. The water tank 29 completely wraps the reflection groove 7. After turning on the control panel 47, water flows into the reflection groove 7. Since the water tank 29 is completely fitted with the shell 4, in order to further ensure that the reflection groove 7 is full of water, it is necessary to control the extrusion block 37 to move downward and squeeze the water into the water tank 29.

The measuring box 31 is provided with a measuring hole 35. In this embodiment, the water-absorbing sponge 30 is shown as only one side of the water tank 29, and it can also be both sides of the water tank 29. The test paper 33 is movable at the measuring hole 35. The water-absorbing sponge 30 is adhered to the bottom of the water tank 29 by glue, and the water-absorbing sponge 30 is arranged in a frame shape. The width of the water-absorbing sponge 30 is greater than the wall thickness of the water tank 29, that is, the water-absorbing sponge 30 is not only in contact with the water tank 29 but also with The bottom of the measuring box 31 is fitted, and a measuring hole 35 is provided at the bottom of the measuring box 31. The test paper 33 moves at the measuring hole 35, and the measuring rod 32 is raised and lowered at the measuring hole 35.

The two winding motors are respectively installed in the two cavities and respectively control the rotation of the two traction rollers 36, and the two winding motors rotate synchronously.

[0054] If the volume of the reflection groove 7 is less than the set value, the water in the water tank 29 continues to be squeezed toward the reflection groove 7 under the action of the extrusion block 37, and the water enters the reflection groove 7. The excess water flows out from the contact position between the water tank 29 and the shell 4, and the water-absorbing sponge 30 absorbs the water. At this time, the measuring rod 32 is controlled to move downward and under the control of the two winding motors, part of the test paper 33 is squeezed out from the measuring hole 35, and the test paper 33 is squeezed into the water-absorbing sponge 30 and squeezed. The water absorbed in the water-absorbing sponge 30 is squeezed out and contacts with the test paper 33, and the test paper 33 turns red. After pulling back the measuring rod 32, and controlling the two winding motors to start rotating in the same direction, the test paper 33 is pulled back into the measuring hole 35, and the color sensor 34 recognizes that the test paper 33 turns red. The color sensor 34 is connected to a color-changing buzzer through the control of the PLC controller. At this time, the color-changing buzzer is triggered by the color sensor 34 and makes a sound, which proves that water flows out of the reflection groove 7 and the forming of the reflection groove 7 does not meet the standard.

[0055] Reference Figure 5 and Figure 7The identification component includes a plurality of water-absorbing films 38, a plurality of cloth frames 39, a plurality of plastic films 40, a plurality of pull ropes 41, a pulling component for pulling the pull ropes 41, a third water sensor 43 arranged in the extrusion block 11, and an accelerating component for accelerating dissolution. The water-absorbing film 38 in this embodiment is a film soluble in water such as a starch film or a polyvinyl alcohol film. The bottom surface of the extrusion block 37 is provided with an extrusion hole 44, and the extrusion block 37 is provided with mounting cavities on both sides of the extrusion hole 44. The pulling component includes two pulling motors and two The pulling roller 42 is rotatably connected to the installation cavity, the axial direction of the pulling roller 42 is perpendicular to the movement direction of the pull rope 41, the pull ropes 41 at both ends are fixedly connected to the peripheral walls of the two pulling rollers 42 respectively, the pulling motor is fixed in the installation cavity and is used to control the movement of the pull rope 41, and the plurality of pull ropes 41 are used to connect the cloth frame 39 and the plastic film 40, the area of ​​the plastic film 40 is larger than the area of ​​the extrusion hole 44, and in this embodiment, a guide roller 48 is installed in the installation cavity, the plastic film 40 is tightly fitted with the extrusion hole 44, and even when the extrusion block 37 squeezes the water in the water tank 29, the plastic film 40 is tightly fitted with the extrusion hole 44, and even when the extrusion block 37 squeezes the water in the water tank 29, the plastic film 40 is tightly fitted with the extrusion hole 44. The film 40 can still block the extrusion hole 44; the plastic film 40 blocks the extrusion hole 44 after it is completely attached to the extrusion hole 44, the plastic film 40 and the water-absorbing film 38 are arranged at intervals, the water-absorbing film 38 is fixed in the cloth frame 39, the cloth frame 39 is adapted to the extrusion hole 44, the movement direction of the water-absorbing film 38 is arranged perpendicular to the movement direction of the third water sensor 43, and the lifting of the third water sensor 43 is set by the electric push rod; the acceleration component includes an acceleration box 45 fixedly arranged on the outer wall of the water tank 29, an acceleration tube 46 fixedly connected to the water tank 29, and a solenoid valve arranged on the acceleration tube 46, The other end of the accelerating tube 46 is arranged in the water tank 29. The accelerating box 45 is filled with quicklime. One end of the accelerating tube 46 is fixed to the bottom of the accelerating box 45. The accelerating tube 46 is arranged obliquely, and the bottom end of the accelerating tube 46 is connected to the water tank 29. The position where the accelerating tube 46 is connected to the water tank 29 is located below the extrusion block 37. When it is necessary to accelerate the dissolution of the water absorption tank, the solenoid valve can be opened after the water enters the reflecting tank 7. The quicklime powder in the accelerating box 45 enters the water in the reflecting tank 7. The water starts to heat up after encountering the quicklime, thereby accelerating the dissolution of the water absorption film 38.

[0056] At the initial position, the plastic film 40 blocks the extrusion hole 44. When the volume of the water tank 29 is smaller than the volume of the reflecting groove 7, the water in the water tank 29 completely enters the reflecting groove 7. At this time, the test paper 33 has not changed. At this time, the third water sensor 43 needs to be controlled to move downward. At the same time, the water absorption film 38 needs to be pulled to the bottom of the third water sensor 43. The third water sensor 43 drives the water absorption film 38 to move into the reflecting groove 7. The third water sensor 43 is wrapped by the water absorption film 38 until the third water sensor 43 moves to the bottom of the opening of the reflecting groove 7. The water absorption film 38 dissolves in water. After the third water sensor 43 recognizes water, the third water sensor 43 is controlled by the PLC controller to be connected to the third buzzer. The third buzzer is triggered to make a sound, which proves that the volume of the reflecting groove 7 is smaller than the volume of the water tank 29 and the forming of the reflecting groove 7 does not meet the standard. Only when the third water sensor 43 just moves to the opening of the reflecting groove 7, the third buzzer makes a sound, which proves that the reflecting groove 7 meets the standard.

[0057] The implementation principle of the production process of a ship sea sweeping light in the embodiment of the present application is as follows: the first water sensor 14 is connected to the first buzzer 15 through the control of the PLC controller. When the fixed rod 13 moves with the extrusion plate 10, the first water sensor 14 is installed in the installation groove at the bottom end of the fixed rod 13, that is, to ensure that the bottom end of the first water sensor 14 and the bottom end of the fixed rod 13 are on the same horizontal plane, when the first water sensor 14 moves into the measuring cylinder 16 and is extruded into the reflecting groove 7 with the extrusion block 11, at this time, if the first water sensor 14 just encounters the liquid level in the measuring cylinder 16, the first water sensor 14 triggers the first buzzer The buzzer 15 starts to make a sound, which proves that the extrusion work of the reflection groove 7 is completed; when the fixed rod 13 moves to the liquid level and enters from the side hole 25 and contacts the dissolving film 21, the dissolving film 21 is dissolved, and the second water sensor 23 triggers the second buzzer 24 to make a sound, which proves that the depth of the reflection groove 7 exceeds the maximum error allowable value, and the movement distance of the extrusion block 11 needs to be adjusted. When the fixed rod 13 moves to the outside of the measuring cylinder 16, water flows out of the side hole 25, and the traction motor controls the first winding roller 26 to rotate, and the new dissolving film 21 is pulled to the position of the side hole 25 to protect the second water sensor 23.

[0058] If the volume of the reflection groove 7 is less than the set value, the water in the water tank 29 continues to be squeezed toward the reflection groove 7 under the action of the extrusion block 37, and the water enters the reflection groove 7. The excess water flows out from the contact position between the water tank 29 and the shell 4, and the water-absorbing sponge 30 absorbs the water. At this time, the measuring rod 32 is controlled to move downward and under the control of the two winding motors, part of the test paper 33 is squeezed out from the measuring hole 35, and the test paper 33 is squeezed into the water-absorbing sponge 30 and squeezed. The water absorbed in the water-absorbing sponge 30 is squeezed out and contacts with the test paper 33, and the test paper 33 turns red. After pulling back the measuring rod 32, and controlling the two winding motors to start rotating in the same direction, the test paper 33 is pulled back into the measuring hole 35, and the color sensor 34 recognizes that the test paper 33 turns red. The color sensor 34 is connected to a color-changing buzzer through the control of the PLC controller. At this time, the color-changing buzzer is triggered by the color sensor 34 and makes a sound, which proves that water flows out of the reflection groove 7 and the forming of the reflection groove 7 does not meet the standard.

[0059] At the initial position, the plastic film 40 blocks the extrusion hole 44. When the volume of the water tank 29 is smaller than the volume of the reflecting groove 7, the water in the water tank 29 completely enters the reflecting groove 7. At this time, the test paper 33 has not changed. At this time, the third water sensor 43 needs to be controlled to move downward. At the same time, the water absorption film 38 needs to be pulled to the bottom of the third water sensor 43. The third water sensor 43 drives the water absorption film 38 to move into the reflecting groove 7. The third water sensor 43 is wrapped by the water absorption film 38 until the third water sensor 43 moves to the bottom of the opening of the reflecting groove 7. The water absorption film 38 dissolves in water. After the third water sensor 43 recognizes water, the third water sensor 43 is controlled by the PLC controller to be connected to the third buzzer. The third buzzer is triggered to make a sound, which proves that the volume of the reflecting groove 7 is smaller than the volume of the water tank 29 and the forming of the reflecting groove 7 does not meet the standard. Only when the third water sensor 43 just moves to the opening of the reflecting groove 7, the third buzzer makes a sound, which proves that the reflecting groove 7 meets the standard.

Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
