[0022] Embodiment 1

[0023] like Figure 1 As shown:

[0024] A loose earth support device for geotechnical engineering investigation comprises a support plate 1.

[0025] In this implementation scheme: the existing {public announcement number}: CN215252946U discloses a loose earth support device for geotechnical engineering investigation projects. This patent discloses a baffle. The support plate 1 in this application document adopts the same technical means in this prior art. This technical means will not be described here one by one. For details about the improvement of this prior art, please refer to the disclosed technology below; to solve the technical problems existing in this prior art, as disclosed in the background technology above, "when encountering landslides or falling rocks, the device will still cause certain hidden dangers to the personal safety of the staff, and it is difficult to respond according to landslides and falling rocks, which is not conducive to the safety of the investigation work." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve the above problems, a protective plate 2 and a transmission rod 3 are added on this basis.

[0026] More specifically:

[0027] like Figure 1 - Figure 4 As shown:

[0028] In combination with the above content: it also includes a protective plate 2, a transmission rod 3, a slider 4, a guide column 5, a limit plate 6 and a spring 7 arranged on one side of the support plate 1, one side of the support plate 1 is rotationally connected to one side of the protective plate 2, and the surface of the protective plate 2 is also rotationally connected to one end of the transmission rod 3, and the other end of the transmission rod 3 is rotationally connected to the surface of the slider 4, and at the same time, the surface of the slider 4 and the guide column 5 are slidingly connected, one end of the guide column 5 is fixedly installed on the surface of the support plate 1, and the other end of the guide column 5 is fixedly installed with a limit plate 6 that is fitted and connected to the slider 4, and the side surface of the slider 4 away from the limit plate 6 is fixedly connected to one end of the spring 7, and at the same time, the spring 7 is sleeved on the surface of the guide column 5.

[0029] In this embodiment: when the staff is conducting survey work, their position is above the support plate 1, and the two sides of the support plate 1 will block the gravel and earth, and the protective plate 2 and the transmission rod 3 will remain in a vertical state under the push of the spring 7 and the slider 4, and the top of the slider 4 and the limit plate 6 will remain in a fit state, so that the slider 4 is always connected to the guide column 5, and when a landslide occurs or the earth above rolls down, it will first come into contact with the protective plate 2, and the protective plate 2 will transmit the power to the transmission rod 3 under the action of the impact force generated by the sliding of the earth, at this time the transmission rod 3 will push the slider 4 and the guide column 5 to slide, and the spring 7 set at the bottom of the slider 4 will be compressed when the slider 4 slides. At the same time, the transmission rod 3 on the other side of the slider 4 will also be displaced under the movement of the slider 4, and the transmission rods 3 on both sides of the slider 4 will fall down at the same time under the pull of the slider 4, and pull the protective plate 2 and the support plate 1 to rotate. As the protective plate 2 on the impacted side is gradually closed, the protective plate 2 on the other side will rotate at the same angle as the support plate 1 until the two protective plates 2 are connected. At this time, the top of the device will be in a closed state, and the gravel and earth will not pose a threat to the staff. Then the staff can withdraw from the work site. After the earth on the protective plate 2 is cleared, the slider 4 will be reset under the rebound of the spring 7, and the protective plate 2 will also return to a vertical state.

[0030] Going further:

[0031] In an optional embodiment, through holes are evenly formed on the surface of the support plate 1 .

[0032] In this embodiment, the through holes evenly arranged on the surface of the support plate 1 enable the staff to collect and survey the rock and soil outside the support plate 1 through the through holes, and at the same time can reduce the overall weight of the device.

[0033] Going further:

[0034] In an optional embodiment, the protection plate 2 and the transmission rod 3 are symmetrically arranged on both sides of the support plate 1 .

[0035] In this embodiment: the symmetrically arranged protective plates 2 and transmission rods 3 can drive the protective plates 2 on one side to move simultaneously when the protective plates 2 on one side are displaced, which can effectively protect the workers in the support plate 1 and ensure the safety of their working environment.

[0036] Going further:

[0037] In an optional embodiment, one end of the transmission rod 3 close to the protective plate 2 is higher than the other end of the transmission rod 3 .

[0038] In this embodiment, the inclined transmission rod 3 can drive the lower end of the transmission rod 3 to descend when rotating between the protection plate 2 and the support plate 1, so that the protection plate 2 can be closed more tightly and the protection work can be carried out more thoroughly.

[0039] Going further:

[0040] In an optional embodiment, a through hole matching the guide post 5 is formed on the surface of the slider 4 .

[0041] In this embodiment: the through hole opened on the surface of the slider 4 can make the sliding between the slider 4 and the guide column 5 more stable, thereby making the movement of the transmission rod 3 and the protective plate 2 smoother, so that the protective work can be achieved by closing the protective plate 2.

[0042] Going further:

[0043] In an optional embodiment, the connection point between the guide column 5 and the support plate 1 is located at the midpoint of the support plate 1 .

[0044] In this embodiment: the guide column 5 located at the midpoint of the support plate 1 can provide a stable fulcrum for the slider 4, and when the protective plate 2 rotates, the force on both sides of the guide column 5 can be more uniform, so that the closing of the protective plate 2 can be more stable.

[0045] The working principle and use process of the utility model are as follows: when the staff is conducting survey work, their position is above the support plate 1, and the two sides of the support plate 1 will block the gravel and earth, and the protective plate 2 and the transmission rod 3 will remain in a vertical state under the push of the spring 7 and the slider 4, and the top of the slider 4 and the limit plate 6 will remain in a fit state, so that the slider 4 is always connected to the guide column 5, and when a landslide occurs or the earth above rolls down, it will first come into contact with the protective plate 2, and the protective plate 2 will transmit the power to the transmission rod 3 under the action of the impact force generated by the sliding of the earth, at this time the transmission rod 3 will push the slider 4 and the guide column 5 to slide, and the spring 7 set at the bottom of the slider 4 will slide when the slider 4 slides When the slider 4 is pressed, the transmission rod 3 on the other side of the slider 4 will also be displaced by the movement of the slider 4, and the transmission rods 3 on both sides of the slider 4 will fall down at the same time under the pull of the slider 4, and pull the protective plate 2 and the support plate 1 to rotate. As the protective plate 2 on the impacted side is gradually closed, the protective plate 2 on the other side will rotate at the same angle as the support plate 1 until the two protective plates 2 are connected. At this time, the top of the device will be in a closed state, and the gravel and earth will not pose a threat to the staff. The staff can then withdraw from the work site. After the earth above the protective plate 2 is cleared, the slider 4 will be reset by the rebound of the spring 7, and the protective plate 2 will also return to a vertical state.

[0046] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
