DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 A multi-section prefabricated water supply well in this embodiment includes, from bottom to top, a lower component 1, a middle component 2, an upper component 3 and a cover body 4. The bottoms of the middle component 2 and the upper component 3 are both provided with sealing rings 5, the tops of the lower component 1 and the middle component 2 are both provided with docking grooves 6, and the front sides of the middle component 2 and the upper component 3 are both provided with sealing mechanisms 7.

[0022] Fixing members 8 are provided on the front, rear, left and right sides of the lower component 1, the middle component 2 and the upper component 3. The four fixing members 8 each include a fixing plate, and each fixing plate is provided with a threaded hole.

[0023] When assembling the prefabricated water supply well together, a preliminary connection is made by inserting two sealing rings 5 ​​into the corresponding two docking grooves 6, and then the bolts are screwed into the threaded holes to further fix the connection so that the lower component 1, the middle component 2 and the upper component 3 can be stably fixed together.

[0024] The sealing mechanism 7 includes a box body 701 and a shell 702. The box body 701 and the shell 702 located at the bottom of the box body 701 are fixedly installed on the front sides of the middle component 2 and the upper component 3. A disc 703 is rotatably installed inside the two box bodies 701. Trapezoidal blocks 704 are movably installed on the left sides of the two discs 703. Springs 705 are fixedly installed between the left sides of the two trapezoidal blocks 704 and the left inner wall of the box body 701. Inflatable components 706 are arranged inside the two shells 702.

[0025] The two inflatable components 706 each include a vertical rod 71. The tops of the two shells 702 are penetrated by vertical rods 71 ​​extending into the interior of the box body 701. The bottoms of the two vertical rods 71 ​​are fixedly mounted with pistons 72 that are slidably connected to the inner wall of the shell 702. A spring 73 that is sleeved on the outer surface of the vertical rod 71 is fixedly mounted between the inner top wall of the shell 702 and the top of the piston 72.

[0026] A hand-cranked disk extending into the interior of the box body 701 and fixedly connected to the disk 703 is rotatably installed on the front side of the two box bodies 701. The hand-cranked disk drives the disk 703 to rotate, controls the operation of the sealing mechanism 7, and realizes the inflation of the interior of the sealing ring 5.

[0027] Four push rods are installed at equal distances on the outer surfaces of the two disks 703. Through the rotation of the four push rods and the cooperation between the trapezoidal block 704 and the expansion and contraction of the spring 1 705, the trapezoidal block 704 can be moved back and forth left and right.

[0028] Slide grooves are provided on the inner top walls of the two box bodies 701, and slide bars slidably connected to the slide grooves are fixedly installed on the tops of the two trapezoidal blocks 704. The slide grooves and the slide bars improve the stability of the trapezoidal blocks 704 when they move left and right.

[0029] The inclined surfaces of the two trapezoidal blocks 704 are slidably connected to the top of the vertical rod 71. With the left and right movement of the trapezoidal blocks 704 and the expansion and contraction of the spring 2 73, the vertical rod 71 can drive the piston 72 to move up and down reciprocatingly in the housing 702, thereby squeezing the air pressure into the interior of the sealing ring 5.

[0030] An inflation tube is connected between the two shells 702 and the sealing ring 5. The function of the inflation tube is to allow the air pressure in the shell 702 to smoothly enter the interior of the sealing ring 5. After the sealing ring 5 expands, it fills the gap between the docking groove 6, thereby making the connection tighter, thereby improving the sealing of the connection.

[0031] The right sides of the two shells 702 are both provided with air vents, and sealing plugs are inserted into the two air vents. When the sealing plugs are opened, the gas in the sealing ring 5 can be discharged from the air vents.

[0032] When implementing, follow these steps:

[0033] 1) First, dock the lower component 1, the middle component 2 and the upper component 3 together. At this time, the sealing ring 5 at the bottom of the upper component 3 is located in the docking groove 6 at the top of the middle component 2, and the sealing ring 5 at the bottom of the middle component 2 is located in the docking groove 6 at the top of the lower component 1, and they are preliminarily connected;

[0034] 2) Then the lower component 1, the middle component 2 and the upper component 3 are further fixed by the fixing member 8;

[0035] 3) The hand-cranked plate is then rotated to drive the disc 703 to rotate, and the disc 703 drives the four push rods to rotate to squeeze the trapezoidal block 704. Under the contraction of the spring 1 705, the trapezoidal block 704 moves back and forth left and right. Under the contraction of the spring 2 73, the vertical rod 71 drives the piston 72 to move up and down in the housing 702, thereby squeezing the air pressure in the housing 702 to the inside of the sealing ring 5.

[0036] 4) Finally, the sealing ring 5 expands to fill the gap with the docking groove 6.

[0037] In summary, the multi-section spliced ​​prefabricated water supply well improves the connection sealing between the lower component 1, the middle component 2 and the upper component 3 by setting the sealing ring 5 and the docking groove 6, and the sealing mechanism 7 can inflate the inside of the sealing ring 5 to expand the sealing ring 5 and fill the gap between the sealing ring 5 and the docking groove 6, thereby improving the tightness of the connection, effectively ensuring the sealing of the connection, and reducing the possibility of leakage caused by deformation of the sealing ring 5.
