[0028] As can be seen from the above technical solutions, the present invention has the following advantages:

[0029] This invention provides an underground pipeline warning device, comprising a emitting cover and a rotary drive assembly disposed on the emitting cover; the emitting cover has an emitting cavity opening to both sides, and a laser assembly is disposed within the emitting cavity; a projection assembly is movably connected to one side of the emitting end of the laser assembly in the emitting cavity; the projection assembly is slidably connected to the rotary drive assembly; a rotating assembly is disposed on the cover of the emitting cover, and the rotating assembly is drively connected to the rotary drive assembly; a plurality of air inlets are disposed on the outer wall of the emitting cover surrounding the laser assembly.

[0030] In practical applications of this invention, the laser component emits a laser beam, which passes through the emission cavity and is irradiated into the projection component. The beam then projects a pre-set warning message onto a designated warning location, thus indicating the non-construction location of underground power grid pipelines. This allows construction personnel to pinpoint the location of underground power grid pipelines, reducing the risk of construction accidents. Furthermore, in this invention, the outer casing has a rotation drive component, which is connected to the rotating component. Through this transmission, the outer casing, which has several air holes, rotates, creating turbulence around the casing. This allows air to continuously flow in and out of the casing through the air inlets, ensuring airflow within the emission cavity. This accelerates heat dissipation from the laser component, preventing overheating and damage, extending the device's lifespan, and better indicating the non-construction location of underground power grid pipelines. Additionally, in this invention, a limiting function exists between the rotation drive component and the projection component. Therefore, when the outer casing rotates, the projection component does not rotate with it, improving both the heat dissipation effect and the projection quality of the warning message, thus further enhancing the indication of the non-construction location of underground power grid pipelines.

[0043] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0044] Please see Figure 1 , Figure 1 This is a schematic diagram of an underground pipeline warning device provided in an embodiment of the present invention.

[0045] This embodiment provides an underground pipeline warning device, comprising: a emitting cover 1 and a rotary drive assembly 2 disposed on the emitting cover 1; the emitting cover 1 is provided with an emitting cavity 11 opening to both sides, the emitting cavity 11 is provided with a laser assembly 3, a projection assembly 4 is movably connected to a first side of the emitting cavity 11, the first side is located at the emitting end of the laser assembly 3, and the projection assembly 4 is slidably connected to the rotary drive assembly 2; a rotating assembly 13 is disposed on the cover of the emitting cover 1, and the rotating assembly 13 is drively connected to the rotary drive assembly 2;

[0046] The first outer wall of the emitting cover 1 is provided with a plurality of air inlets 12, and the position of the first outer wall corresponds to the position of the laser component 3.

[0047] It should be noted that, as Figures 1-2 As shown, the laser component 3 is located on the right side inside the emission cavity 11, with the emission end on the left side of the laser component 3. The first side of the emission cavity 11 is located at the emission end. The first peripheral cover is located outside the mounting cavity area where the laser component 3 is located, that is, the laser component 3 is housed within the first peripheral cover.

[0048] In practical use, the underground pipeline warning device provided in this embodiment is installed at the predetermined installation location. After the device is turned on, the emitting end of the laser component 3 emits a laser. The laser passes through the emitting cavity 11 and is irradiated onto the projection component 4, thereby projecting the warning information on the projection component 4 onto the designated warning location. This warning location is a non-construction area, which informs construction personnel of the location of the non-construction area and prevents them from damaging the underground power grid pipeline at the projection location, thus providing a warning effect. Furthermore, when the laser component 3 is working, the rotation drive component 2 drives the rotating component 13, and through the connection between the rotating component 13 and the emitting cover 1, the emitting cover 1 is driven to rotate. During the rotation of the emitting cover 1, the surrounding air will form turbulence around the emitting cover 1, so that the flowing air continuously enters and exits the air inlet 12, thus ensuring that there is flowing air in the emitting cavity 11, accelerating the heat dissipation of the surface of the laser component 3, and preventing the laser component 3 from generating too much heat and being damaged due to excessive temperature.

[0049] During the rotation of the outer casing 1, the projection component 4 does not rotate with the outer casing 1 under the limiting effect of the rotation drive component 2, thereby maintaining the quality of the projected image. Furthermore, in this embodiment, the projection distance between the projection component 4 and the laser component 3 can be adjusted by sliding the projection component 4, thereby achieving the effect of adjusting the focal length.

[0050] Understandably, the installation location can be determined based on the actual situation. Warning messages may include text or images.

[0051] In a specific embodiment, such as Figures 1 to 6 As shown, the rotating assembly 13 includes a drive wheel 14 and two rotating rings 15; the drive wheel 14 is sleeved on the launch cover; the two drive wheels 14 are sleeved on the launch cover and are respectively disposed on both sides of the drive wheel 14.

[0052] The rotary drive assembly includes a rotary housing 21 and a drive unit 24; a rotary cavity 22 is provided inside the rotary housing 21, and a mounting cavity 23 is provided on one side of the rotary cavity 22; two rotary rings 15 are rotatably connected to the rotary cavity 22 respectively; the drive unit 24 is provided inside the mounting cavity 23, and a drive wheel 25 is provided at the output end of the drive unit 24, which is connected to the transmission wheel 14; the rotary housing 21 is slidably connected to the projection assembly 4.

[0053] It should be noted that during operation, the outer casing 21 is rotated to the designated installation position to achieve the installation and fixation of the local pipeline warning device.

[0054] When the laser component 3 is cooled, the drive unit 24 drives the transmission wheel 14 to rotate through the drive wheel 25, thereby driving the emission cover 1 to rotate. Under the guidance of the two rotating rings 15, the emission cover 1 rotates stably in the rotating cavity 22, thereby realizing the rotational movement of the emission cover 1. The emission cover 1 drives the surrounding air disturbance, forming an annular air flow channel, so that air circulation is formed in the emission cavity 11, improving the heat dissipation effect of the laser component 3.

[0055] In this embodiment, the drive unit 24 can adopt an existing motor structure, that is, the rotation of the launch cover 1 is realized by the motor.

[0056] It is understood that the drive wheel 25 and the transmission wheel 14 can be transmission wheel sets such as gear sets and synchronous wheel sets. The specific connection methods and working principles are existing technologies and will not be described in detail here.

[0057] In a specific embodiment, such as Figures 1 to 6 As shown, the rotating cavity 22 has rotating openings on both sides, and a rotating protruding ring 26 is provided inside the rotating opening;

[0058] The rotating ring 15 is rotatably connected to the rotating opening, and the ring wall of the rotating ring 15 is provided with a rotating groove 16 that cooperates with the rotating protruding ring 26.

[0059] It should be noted that in this embodiment, the rotating protrusion 26 and the rotating groove 16 are set to guide the rotating ring 15, so that the rotating ring 15 can rotate more stably in the rotating opening, avoiding the problem of abnormal shaking of the launch cover 1 when rotating.

[0060] In a specific embodiment, such as Figures 1 to 6 As shown, a guide seat 27 is provided on one side of the rotating housing 21, and the guide seat 27 is slidably connected to the top of the projection component 4.

[0061] It should be noted that in this embodiment, the projection component 4 can be positioned by setting the guide seat 27 to prevent the projection component 4 from rotating with the outer casing 1.

[0062] In addition, the installation depth between the projection component 4 and the emission housing 1 can be adjusted by the guide seat 27, so as to adjust the projection distance between the projection component 4 and the laser component 3 and achieve the technical effect of focusing.

[0063] In a specific embodiment, such as Figures 1 to 6As shown, the bottom of the guide seat 27 is provided with a sliding groove 28 along the length of the outer casing 1; the projection assembly 4 includes a replacement seat 41 and a projection lens 42; the projection lens 42 is detachably connected to the replacement seat 41; the top of the replacement seat 41 is provided with a slider 43 that cooperates with the sliding groove 28; the side of the replacement seat 41 facing the emission cavity 11 is provided with a guide ring 49 that is slidably connected to the emission cavity 11.

[0064] It should be noted that in practical applications, under the guidance of the slide groove 28 and the slider 43, the replacement seat 41 can slide linearly along the slide groove 28, thereby adjusting the projection distance between the projection lens 42 and the laser component 3.

[0065] In this embodiment, the projection lens 42 can be replaced as needed, and projection lenses 42 with different texts or patterns can be replaced onto the replacement base 41.

[0066] In this embodiment, the relative rotation between the replacement seat 41 and the launching cavity 11 can be made more stable under the action of the guide ring 49.

[0067] It is understood that the projection lens 42 is engraved with specific warning text or patterns, such as the warning text "10KV cable, excavation prohibited". The text is projected onto the plane by shining a laser into the groove of the text, thereby realizing the projection of the image.

[0068] In a specific embodiment, such as Figures 1 to 6 As shown, the replacement base 41 is provided with a light-emitting hole 44; the wall of the light-emitting hole 44 is provided with a slot 46;

[0069] The projection lens 42 is located inside the light outlet 44, and the edge of the projection lens 42 is engaged with the slot 46.

[0070] The replacement base 41 has an insertion slot 45 on one side that communicates with the light output hole 44.

[0071] It should be noted that in this embodiment, when the operator needs to replace the projection lens 42, the old projection lens 42 can be removed from the light outlet hole 44 through the insertion slot 45, and then the new projection lens 42 can be inserted into the light outlet hole 44 through the insertion slot 45, with the edge of the projection lens 42 engaging with the slot 46, thus completing the replacement of the projection lens 42. This embodiment, through the aforementioned components, effectively improves the efficiency of disassembling and assembling the projection lens 42, and enhances the flexibility of the local underground pipeline warning device during use.

[0072] In a specific embodiment, such as Figures 1 to 6 As shown, at least one stop protrusion 47 is provided in the slot 46;

[0073] The edge of the projection lens 42 is provided with a stop groove 48 that is connected to the stop protrusion 47.

[0074] It should be noted that in this embodiment, the stop protrusion 47 and the stop groove 48 are used to prevent the projection lens 42 from rotating in the light outlet hole 44, and to prevent unnecessary shaking or rotation of the projection lens 42 during the projection process, which would affect the projection quality of the image, thereby improving the projection quality.

[0075] In a specific embodiment, such as Figures 1 to 6 As shown, an air intake 12 is provided with a wind-facing arc plate 17 on its exterior, and the arc surface of the wind-facing arc plate 17 faces the rotation direction of the launch cover 1.

[0076] It should be noted that in this embodiment, by setting the windward arc plate 17 to stop the flow of air, the air is allowed to quickly enter the air inlet 12 along the windward arc plate 17, thereby improving the airflow in the emission cavity 11 and improving the overall heat dissipation effect of the laser component 3.

[0077] In addition, in this embodiment, the arc surface of the wind-facing arc plate 17 is set to face the rotation direction of the launch cover 1, so that the wind-facing arc plate 17 can better block the air into the air inlet when rotating, thereby further improving the heat dissipation effect.

[0078] In a specific embodiment, such as Figures 1 to 6 As shown, the laser assembly 3 includes a heat dissipation housing 31 and a laser generator 33; the heat dissipation housing 31 is provided with a mounting through hole 32, and the laser generator 33 is disposed in the mounting through hole 32; the heat dissipation housing 31 is fixedly connected to the emission cavity 11.

[0079] It should be noted that in this embodiment, the laser emitter is wrapped by the heat dissipation shell 31 to increase the contact area between the laser generator 33 and the heat dissipation shell 31, thereby greatly improving the heat dissipation effect of the heat dissipation shell 31 on the laser generator 33.

[0080] In one specific embodiment, the heat dissipation housing 31 has a plurality of heat dissipation fins distributed on it.

[0081] This embodiment enhances the heat dissipation effect of the heat dissipation shell 31 by setting a large number of heat dissipation fins, and also improves the heat exchange effect between the heat dissipation shell 31 and the flowing air.

[0082] In a specific embodiment, such as Figures 1 to 6 As shown, it also includes a laser scattering sheet 34, which is disposed at one end of the mounting through hole 32, and the one end of the through hole is close to the emitting end of the laser generator 33.

[0083] In this embodiment, by setting up a laser scattering lens 34, the laser beam with uneven intensity distribution emitted by the laser generator 33 can be converted into a beam with uniform intensity, so that the light spot projected by the lens is flatter and the indication effect of the local underground pipeline warning device is improved.

[0084] In summary, when using the underground pipeline warning device provided in this embodiment of the invention, the laser component 3 emits a laser beam, which passes through the emission cavity 11 and irradiates the projection component 4. The laser beam projects the text or pattern on the projection component 4 onto the designated warning location, thereby improving the warning effect on non-construction areas and preventing construction personnel from damaging the non-construction area of ​​the underground power grid pipeline at the projection location. Furthermore, when the laser component 3 is working, the rotation drive component 2 drives the emission housing 1 to rotate via the rotation component 13. When the emission housing 1 rotates, air turbulence is formed around it, and the flowing air continuously enters and exits the air inlet 12, thus creating flowing air within the emission cavity 11. This accelerates heat exchange on the surface of the laser component 3, preventing excessive heat generation and potential damage. Simultaneously, the projection component 4 does not rotate with the emission housing 1 under the limiting effect of the rotation drive component 2, maintaining the quality of the projected image. Additionally, the projection distance between the projection component 4 and the laser component 3 can be adjusted by sliding the projection component 4, thereby achieving the effect of adjusting the focal length.
