[0031] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation of the present utility model. On the contrary, the embodiments of the present utility model include all changes, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0032] The engineering surveying and mapping warning device of the embodiment of the present utility model will be described below in conjunction with the accompanying drawings.

[0033] As Figures 1-7 shown, the engineering surveying and mapping warning device of the embodiment of the present utility model includes a frame 1, a warning frame 2, a sliding mechanism 3 and a surface cleaning mechanism 4. Among them, the sliding mechanism 3 is arranged on the connecting rod 11 in the frame 1; the warning frame 2 is arranged on the sliding mechanism 3; the surface cleaning mechanism 4 is arranged on the warning frame 2 and is connected to one end of the sliding mechanism 3; among them, the sliding mechanism 3 includes a bracket 31, a connecting shaft seat 32 and a guide rod 33. Among them, the connecting shaft seats 32 are symmetrically threadedly connected to the outer surface of the bracket 31. The warning frame 2 is located inside the bracket 31. One end of the connecting shaft seat 32 is connected to one end of the connecting rod 11 through a pin shaft. The other end of the connecting shaft seat 32 penetrates into the inside of the bracket 31 and is slidably connected to the upper inner wall of the warning frame 2. One end of the guide rod 33 is rotatably connected to the inner surface of the bracket 31 and is located on one side of the bottom of the connecting shaft seat 32; the surface cleaning mechanism 4 includes a sliding frame 41, a sponge cleaning seat 42 and an elastic clamping member 43. Among them, the sliding frame 41 is vertically slidably connected to the surface of the warning frame 2 and is rotatably connected to the other end of the guide rod 33. The sponge cleaning seat 42 is horizontally slidably connected to the inner wall of the sliding frame 41 and is attached to the surface of the warning frame 2. The sponge cleaning seat 42 is clamped and fixed to the inner wall of the sliding frame 41 through the elastic clamping member 43.

[0034] It should be noted that a glass is provided on one side surface of the warning frame 2 close to the sponge cleaning seat 42. A counterweight block, an LED lamp, a rotating cylinder and a warning cloth are arranged inside the warning frame 2. The above are prior arts and will not be elaborated here.

[0035] It can be understood that in the vertical state, the sponge cleaning seat 42 is located on one side of the bottom of the glass in the warning frame 2. In the inclined state, the sponge cleaning seat 42 moves upward along the surface of the warning frame 2 and the glass surface. When the swing angle of the warning frame 2 reaches the maximum value, the sponge cleaning seat 42 has moved from one side of the bottom of the glass in the warning frame 2 to one side of the top of the glass.

[0036] Specifically, when in use, when a strong wind blows the warning frame 2, since the warning frame 2 is slidably connected to the connecting shaft seat 32, when the strong wind blows the warning frame 2, the warning frame 2 can rotate around the connecting shaft seat 32 following the strong wind, changing from the vertical state to the inclined state. In the vertical state of the warning frame 2, affected by the guide rod 33, the sliding frame 41 and the sponge cleaning seat 42 are located on one side of the bottom of the glass. In the inclined state of the warning frame 2, affected by the guide rod 33, the sliding frame 41 will drive the sponge cleaning seat 42 to move upward along the surface of the warning frame 2 and clean the glass surface during the movement. When the strong wind stops, the warning frame 2 returns to the vertical state under the action of the internal counterweight block, and the sliding frame 41 also drives the sponge cleaning seat 42 to reset, that is, move to one side of the bottom of the glass.

[0037] In an embodiment of the present utility model, as Figures 1-3 shown, the sliding mechanism 3 further includes an angle limiting mechanism 5. The angle limiting mechanism 5 includes a limiting shaft 51 and an arc-shaped limiting sliding groove 52. Among them, the limiting shaft 51 is threadedly connected to the outer surface of the warning frame 2, and the arc-shaped limiting sliding groove 52 is formed on the inner surface of the bracket 31 and corresponds to the position of the limiting shaft 51. One end of the limiting shaft 51 is located inside the arc-shaped limiting sliding groove 52 and is slidably connected to the inner wall of the arc-shaped limiting sliding groove 52.

[0038] It should be noted that the angle limiting mechanism 5 described in this embodiment is used to limit the swinging angle of the warning frame 2.

[0039] It should also be noted that the swinging angle of the warning frame 2 is adapted to the moving stroke of the sponge cleaning seat 42.

[0040] Specifically, the rotation of the warning frame 2 synchronously drives the limiting shaft 51 to move on the inner wall of the arc-shaped limiting sliding groove 52. When the limiting shaft 51 moves to one end of the inner wall of the arc-shaped limiting sliding groove 52, the rotation angle of the warning frame 2 is limited, and the corresponding sponge cleaning seat 42 also moves to the maximum value of the stroke, that is, to one side of the top of the glass.

[0041] In an embodiment of the present utility model, as Figures 1-2 shown, the sliding mechanism 3 further includes a limiting and stabilizing mechanism 6. The limiting and stabilizing mechanism 6 includes a convex block 61 and a groove 62. Among them, the convex blocks 61 are symmetrically and fixedly connected to the outer surface of the bracket 31, and the grooves 62 are respectively formed on the inner surfaces of the two groups of connecting rods 11 and correspond to the positions of the convex blocks 61. The convex blocks 61 are clamped and fixed on the inner walls of the grooves 62; the width of the grooves 62 is the same as the width of the convex blocks 61, and the height of the grooves 62 is greater than the height of the convex blocks 61.

[0042] Specifically, the convex blocks 61 and the grooves 62 are provided to improve the structural stability of the bracket 31 in the vertical state, and the use effect is good. When the bracket 31 and the connecting rod 11 are both in the vertical state, the structural stability can be further improved by the clamping of the convex blocks 61 and the grooves 62. The same width ensures stable clamping, and the difference in height facilitates the convex blocks 61 to enter the inside of the grooves 62.

[0043] In an embodiment of the present utility model, as Figure 2 and Figure 4As shown in the figure, at the positions corresponding to the inner wall of the sliding frame 41 and the surface of the warning frame 2, a guiding block 411 and a guiding groove 21 are respectively provided. One end of the guiding block 411 is located inside the guiding groove 21 and is slidably connected to the inner wall of the guiding groove 21. At the position corresponding to the sponge cleaning seat 42 on the surface of the sliding frame 41, an installation groove 412 is formed. The inner wall of the installation groove 412 is symmetrically provided with clamping holes 413. The sponge cleaning seat 42 is located inside the installation groove 412 and is attached to the surface of the warning frame 2. The elastic clamping member 43 corresponds to the clamping holes 413 and is clamped and fixed.

[0044] Specifically, the guiding block 411 and the guiding groove 21 are provided to improve the structural stability when the sliding frame 41 moves. The installation groove 412 is provided for installing the sponge cleaning seat 42. The clamping holes 413 are provided for clamping and fixing with the elastic clamping member 43, so as to facilitate the positioning of the sponge cleaning seat 42.

[0045] In an embodiment of the present utility model, as Figures 4-7 shown, the sponge cleaning seat 42 includes a seat body 421, rollers 422, a cleaning roller 423, a sponge pad 424, a gear reduction mechanism 425 and a one-way transmission 426. Among them, the seat body 421 is clamped and fixed to the inner wall of the installation groove 412 through the elastic clamping member 43. The rollers 422 are symmetrically and rotatably connected to the inner wall of the seat body 421. One end of the rollers 422 penetrates out of the seat body 421 and is attached to the surface of the warning frame 2. The cleaning roller 423 is rotatably connected to the inner wall of the seat body 421 and is located between the two groups of rollers 422. The sponge pad 424 is adhesively fixed to the outer side of the cleaning roller 423. One end of the sponge pad 424 penetrates out of the seat body 421 and is attached to the surface of the warning frame 2. The gear reduction mechanisms 425 are symmetrically arranged inside the seat body 421 and are located outside the cleaning roller 423. One end of the gear reduction mechanism 425 is connected to one end of the central axis of the cleaning roller 423, and the other end of the gear reduction mechanism 425 is connected to one end of the central axis of the roller 422 through the one-way transmission 426.

[0046] It should be noted that in this embodiment, the sponge pad 424 is adhesively fixed to the surface of the cleaning roller 423 through a magic tape. After the sponge pad 424 is wound around the cleaning roller 423 for one circle, a sponge ring is formed.

[0047] It should also be noted that the one-way transmission 426 is a ratchet-type one-way transmission. The structures and connection relationships of the gear reduction mechanism 425 and the one-way transmission 426 are all prior arts, so they will not be elaborated here.

[0048] It can be understood that to facilitate the switching of the cleaning area of the sponge pad 424, the sponge pad 424 needs to be kept rotating in one direction. To prevent the sponge pad 424 from rotating on its own, a damping ring is provided at the connection between the central axis surface of the cleaning roller 423 and the inner wall of the seat body 421. The damping ring is designed to effectively prevent the cleaning roller 423 from rotating on its own. Among them, the force that drives the cleaning roller 423 to rotate by the gear reduction mechanism 425 is greater than the resistance of the damping ring.

[0049] It can also be understood that the cleaning roller 423 corresponds to the position of the glass, and through grooves for the sponge pad 424 and the roller 422 to pass through are provided on the surface of the seat body 421.

[0050] Specifically, the structure and connection relationship of the sponge cleaning seat 42 are further described. During use, the synchronous movement of the sliding frame 41 drives the synchronous movement of the seat body 421. The synchronous movement of the seat body 421 drives the roller 422 and the sponge pad 424 to move upward along the surface of the warning frame 2 respectively. Since a damping ring is provided at the connection between the central axis surface of the cleaning roller 423 and the inner wall of the seat body 421, during the upward movement of the sponge pad 424 along the surface of the warning frame 2, the position of the sponge pad 424 remains unchanged. Since a one-way transmission 426 is provided between the roller 422 and the gear reduction mechanism 425, and the one-way transmission 426 is set to be able to achieve transmission only in the case of reverse rotation, that is, the roller 422 can drive the gear reduction mechanism 425 to operate through the one-way transmission 426 only when moving downward along the surface of the warning frame 2. Therefore, during the upward movement of the roller 422 along the surface of the warning frame 2, the roller 422 does not drive the gear reduction mechanism 425 to operate through the one-way transmission 426. During the downward movement of the sponge pad 424 along the surface of the warning frame 2, the rotation of the roller 422 synchronously drives the gear reduction mechanism 425 to operate through the one-way transmission 426. The operation of the gear reduction mechanism 425 synchronously drives the cleaning roller 423 to rotate slowly, and the cleaning roller 423 rotates to slowly switch the cleaning area of the sponge pad 424, thereby effectively cleaning the glass surface and having a good use effect.

[0051] In an embodiment of the present invention, as Figures 5-6 shown, the sponge cleaning seat 42 further includes an elastic connection mechanism 7. The elastic connection mechanism 7 includes a horizontal transmission key barrel 71, a spring 72, and a single-key lever 73. Among them, the horizontal transmission key barrel 71 is horizontally slidably connected to the outer surface of one end of the gear reduction mechanism 425, and a spring 72 is fixedly connected between the horizontal transmission key barrel 71 and the surface of the gear reduction mechanism 425. The single-key lever 73 is fixedly connected to the outer surface of one end of the central axis of the cleaning roller 423. One end of the single-key lever 73 is located inside the horizontal transmission key barrel 71 and is slidably connected to the inner wall of the horizontal transmission key barrel 71.

[0052] It should be noted that the elastic connection mechanism 7 described in this embodiment can not only achieve transmission but also facilitate the disassembly and assembly of the cleaning roller 423, so as to quickly replace the sponge pad 424, with strong practicability and good use effect.

[0053] It should also be noted that a key groove (not shown in the figure) adapted to the outer dimension of the one-way key rod 73 is provided on the inner wall of the horizontal transmission key cylinder 71.

[0054] Specifically, during use, the horizontal transmission key cylinder 71 is toggled outward. The horizontal transmission key cylinder 71 is forced to move horizontally outward along one end of the gear reduction mechanism 425 and compress the spring 72. Then, the cleaning roller 423 with the sponge pad 424 replaced is placed, and its one-way key rod 73 is aligned with the key groove in the horizontal transmission key cylinder 71. Then, the horizontal transmission key cylinder 71 is released. The horizontal transmission key cylinder 71 is directly sleeved on the outside of the one-way key rod 73 under the elastic force of the spring 72. The rotation of the cleaning roller 423 can be synchronously driven through the cooperation between the one-way key rod 73 and the key groove of the horizontal transmission key cylinder 71.

[0055] In summary, for the engineering surveying and mapping warning device of the embodiment of the present utility model, a sliding mechanism 3 and a surface cleaning mechanism 4 are added to the existing warning device. When the warning frame 2 shakes under the influence of strong wind, the sliding mechanism 3 can cleverly drive the surface cleaning mechanism 4 synchronously to immediately clean the glass on the surface of the warning frame 2. By appropriately cleaning the glass surface, the cleanliness of the glass surface is effectively ensured, and thus the stability and clarity of the warning effect are guaranteed. It has strong practicability and good use effect.
