Detailed Implementation

[0024] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.

[0025] Example 1

[0026] like Figure 1-5 As shown, a downhole safety protection frame includes a left support plate 1 and a right support plate 2. A front baffle 3 and a rear baffle 4 are rotatably connected between the left support plate 1 and the right support plate 2. The upper ends of the front baffle 3 and the rear baffle 4 are coaxially rotatably connected and controlled to open and close by an opening and closing drive device. The inner surfaces of the front baffle 3 and the rear baffle 4 are provided with storage slots 5 for storing necessities. A folding plate assembly for providing bottom support is connected between the front baffle 3 and the rear baffle 4. The folding plate assembly includes a first connecting plate 6 and a second connecting plate 7. One end of the first connecting plate 6 is rotatably connected to... Attached to the lower end of the front baffle 3, one end of the second connecting plate 7 is rotatably connected to the lower end of the rear baffle 4. After the front baffle 3 and the rear baffle 4 are unfolded, they form a triangle with two side supports. The first connecting plate 6 and the second connecting plate 7 can be unfolded and connected to form a bottom support. The left support plate 1 and the right support plate 2 form side protection, forming a horizontally placed triangular prism structure with higher sealing performance. It can form all-round protection and has high structural stability. The internal storage compartment 5 can store emergency supplies and necessities as temporary survival support, improving the chances of survival and the success rate of rescue.

[0027] Furthermore, the inner side of the front baffle 3 is provided with a first storage groove 8, and the inner side of the rear baffle 4 is provided with a second storage groove 9. In the non-working state, the first connecting plate 6 and the second connecting plate 7 are respectively stored in the first storage groove 8 and the second storage groove 9. In the working state, the first connecting plate 6 and the second connecting plate 7 are flipped and connected to each other by the buckles at the ends.

[0028] Furthermore, auxiliary display screens 10 are installed on the left support plate 1 and the right support plate 2, which can display important environmental information and safety prompts in real time, providing additional safety for downhole workers.

[0029] Furthermore, an arc-shaped notch 11 is provided at the bottom middle of the left support plate 1 and the right support plate 2. The bottom of the arc-shaped notch 11 forms a drain outlet 12, and the arc-shaped notch 11 can form an arch support. The two sides of the arc-shaped notch 11 can provide stable support. The left support plate 1 and the right support plate 2 work together to form a four-legged support, ensuring sufficient stability and strength.

[0030] Furthermore, the vertical dimensions of the left support plate 1 and the right support plate 2 are greater than the maximum vertical length of the front baffle 3 and the rear baffle 4, which can lift the first connecting plate 6 and the second connecting plate 7 off the ground, avoiding the impact of uneven or damp ground on the bottom support.

[0031] Furthermore, an alarm 13 is installed on the upper end of the front baffle 3 or the rear baffle 4.

[0032] Furthermore, the opening and closing drive device adopts a drive motor, and the rear baffle 4 is rotatably connected to the front baffle 3 through the hinge shaft 14. The drive motor is installed on the front baffle 3 and drives the connection to the hinge shaft 14.

[0033] Furthermore, a handle 15 is fixedly connected to the front baffle 3 to facilitate manual flipping of the front baffle 3.

[0034] Furthermore, partitions are fixedly connected to both the left support plate 1 and the right support plate 2. The partitions are inserted between the front baffle 3 and the rear baffle 4. When manually flipped, the rear baffle 4 will no longer flip with the front baffle 3, making it easy to unfold. After unfolding, the front baffle 3 flips out the left support plate 1 and the right support plate 2, and the left and right sides of the flipped-out part can form entrances for people to enter.

[0035] Example 2

[0036] The difference from Embodiment 1 is that the first connecting plate 6 and the second connecting plate 7 are hinged to each other, the first storage slot 8 and the second storage slot 9 are similar in size, and the first connecting plate 6 and the second connecting plate 7 can always remain connected, which facilitates quick unfolding.

[0037] Example 3

[0038] Based on Embodiment 1 or Embodiment 2, a controller and a signal transmission unit are installed in the front baffle 3 or the rear baffle 4, the controller is electrically connected to the signal transmission unit, and the alarm 13 is electrically connected to the controller.

[0039] A frequency sensor for identifying sound and vibration frequencies is installed on the front baffle 3, and the frequency sensor is electrically connected to the controller.

[0040] A person presence sensor is installed on the inside of the front baffle 3 or the rear baffle 4.

[0041] A main display screen 16 is installed on the outside of the rear panel 4. The human sensor, the main display screen 16 and the auxiliary display screen 10 are electrically connected to the controller. The main display screen 16 and the auxiliary display screen 10 can display noise decibels, air quality, vibration frequency and temperature and humidity, as well as information on human presence (i.e. whether there is a person inside) to provide operators with comprehensive environmental information and safety assurance.
