A rain shield tile 4 is laid on the top frame 3 and extends out of the tank body 1. One end of a strap 5 is rotatably assembled on the rain shield tile 4, and the other end is overlapped on the rain shield tile 4 of another adjacent tank body 1. A water receiving trough 6 is provided at the inclined end of the rain shield tile 4. The water receiving trough 6 is connected to a drain pipe 7, and the drain pipe 7 is connected to the outside of the well site.

[0036] In this embodiment, the tank body 1 is a drilling fluid circulation tank, which is installed in the drilling well site and is provided with several columns. The columns 2 are used to support the top frame 3 and the rain shielding tiles 4. The columns 2 are installed vertically in a lifting manner to facilitate the installation and transportation of the top frame 3 and the rain shielding tiles 4. The slats 5 are arranged between adjacent tank bodies 1 to shield the area between adjacent circulation tanks from rain. The water receiving trough 6 is used to receive water and drain water, and discharge rainwater to the outside of the well site to prevent rainwater from gathering in the well site.

[0037] In this embodiment, the top frame 3 can be tilted left and right, or tilted front and back, so that rainwater can flow downward. When tilted left and right, the water receiving trough 6 is located at the left and right tilted ends; when tilted front and back, the water receiving trough 6 is located at the front and back tilted ends. At the same time, the arrangement of the plurality of tank bodies 1 can be arranged front and back, and / or left and right, and the bridging board 5 covers the area between adjacent tank bodies 1.

[0038] Example 2

[0039] This embodiment is further described on the basis of embodiment 1. Figure 1 , Figure 2 and Figure 6 As shown, column boxes 8 are arranged outwardly at the four corners of the top of the tank body 1, and vertical and penetrating column holes are arranged in the column boxes 8. The column 2 passes downward through the column hole, and the column 2 can move up and down in the column hole.

[0040] like Figure 5 As shown, a plurality of column pin holes 9 are arranged on the column 2 along the vertical direction, and a positioning pin hole 10 is arranged on the column box 8. The positioning pin passes through the column pin hole 9 and the positioning pin hole 10 to position the column 2.

[0041] like Figure 6 As shown, a set screw 11 is provided on the column box 8, and the set screw 11 passes through the column box 8 and abuts against the column 2 in the box to stabilize the column 2.

[0042] like Figure 1 As shown, a plurality of detachable support rods 12 are also installed between the tank body 1 and the top frame 3 to support the top frame 3 and the rain shielding tiles 4 thereon.

[0043] Example 3

[0044] This embodiment is further described on the basis of embodiment 2. Figure 3 and Figure 4 As shown, the butt plate 5 is rotatably assembled on the rain shield tile 4 through the ear plate 13. A tile groove 14 is provided at the end of the rain shield tile 4. One end of the butt plate 5 is rotatably assembled on the tile groove 14 through the ear plate 13, and the other end is overlapped on the tile groove 14 of the rain shield tile 4 of another adjacent tank body 1. The butt plate 5 and the tile groove 14 are both U-shaped. The tile groove 14 has two functions, one is to connect the adjacent rain shield tiles 4, and the other is to be used for assembling the butt plate 5.

[0045] like Figure 2 As shown, a support frame 15 is provided at the top of the column 2, and the water tank 6 is installed on the support frame 15. The support frame 15 is a triangular support frame 15, and the vertical rod of the triangular support frame 15 is assembled on the column 2 through the ear seat 16 to support the water tank 6.

[0046] In this embodiment, the outer dimensions of the rain-shielding tile 4 are 11200*2620mm, and a 60*40 rectangular tube is used as the frame. The surface is a 1.2mm cold plate that is folded and corrugated and then spliced ​​and welded. The outer dimensions of the slat 5 are 6000*1080mm, and it is folded with a 3mm steel plate. The slat is connected to the rain-shielding tile through an ear plate. It is turned over by a crane during installation. During transportation, the slat is turned over to the top of the rain-shielding tile. The outer dimensions of the top frame 3 are 9620*2620mm, and it is made of a 100*80 rectangular tube. The column 2 is made of an 80*80 rectangular tube. The outer dimensions of the column box 8 are 110*105*600mm, and it is folded with a steel plate, which increases the front and rear gaps between the column and the column box. The column box is welded to the front and rear ends of the circulation tank, and a set screw is added to the front, left and right sides of the column box. After the column is installed, the positioning pin is inserted and the set screw on the column box is tightened to prevent the column from shaking back and forth.

[0047] In order to better understand the present invention, the following is a complete description of the working principle of the present invention:

[0048] The initial installation of the awning is as follows:

[0049] 1. Install the column box 8: Position the column box 8 according to the design drawing, ensure that the diagonal error of the column box 8 is less than 5mm, and weld the column box 8 to the front and rear ends of the tank body 1.

[0050] 2. Install column 2: Place column 2 in column box 8, with column 2 at the lowest position, and insert the positioning pin.

[0051] 3. Install the top frame 3: Use a crane to lift the top frame 3 above the column 2. Connect the column 2 and the top frame ear plate to each other, and insert the pins and safety pins.

[0052] 4. Install the rain-shielding tile 4: first use a crane to connect the rain-shielding tile 4 and the bridging board 5, flip the bridging board 5 over the rain-shielding tile 4, and then use a crane to lift the rain-shielding tile 4 onto the top frame 3 for installation and connection.

[0053] 5. Lift the frame: Use a crane to slowly lift the frame to prevent the frame from tilting during the lifting process, causing the column 2 and the column box 8 to collide and get stuck. After lifting to the highest point, insert the positioning pins and pins, and tighten the set screws 11 on the column box 8 to prevent the column 2 from shaking back and forth.

[0054] 6. Turn over the scaffolding 5: Use a crane or manpower to turn over the scaffolding 5 to the rain shielding tile 4 of the adjacent tank body 1 to complete the installation of the house frame.

[0055] 7. Install the water receiving trough 6: Install the water receiving trough 6 behind the rain shielding tile 4, and connect the drainage pipe 7 to drain the rainwater outside the well site.

[0056] 8. After the initial installation is completed, the column 2 and the top frame 3 do not need to be removed. They only need to be lowered to a low position for fixing and transported together with the circulation tank. For the secondary installation, refer to the installation steps 4 to 7.

[0057] Common faults and solutions are as follows:

[0058] 1. There is a jam when the awning is lifted

[0059] Cause of the fault: The crane was not stable during lifting, and the awning tilted forward and backward, causing the column 2 and the column box 8 to collide with each other;

[0060] Solution: Adjust the lifting position so that the awning can be lifted vertically.

[0061] 2. The awning is shaking

[0062] Cause of the fault: The column box fixing screw 11 is not tightened, and the gap between the column 2 and the column box 8 increases.

[0063] Solution: Tighten the column box set screw 11.

[0064] The implementation methods of the present invention are described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalents or substitutions are all included in the scope defined by the claims of the present invention.
