The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model is a deep foundation pit drainage structure of an open-cut station, comprising a transverse plate 1 and a drainage pipe 2, a positioning hole 17 is provided in the middle of the transverse plate 1, the drainage pipe 2 is arranged inside the positioning hole 17, a water pump 14 is installed on the upper end of the drainage pipe 2 through a connecting flange, fixed parts 3 are protruded on both side surfaces of the drainage pipe 2, first sealed bearings 16 are embedded on the opposite end surfaces of the fixed parts 3, a shaft rod 4 is provided in the inner ring of the first sealed bearing 16, wheels 5 are installed on the opposite ends of the shaft rod 4, positioning plates 9 for limiting the transverse plate 1 on the deep foundation pit are provided at both ends of the transverse plate 1, and an adjusting mechanism for driving the positioning plate 9 to move is installed on the upper end of the positioning plate 9.
[0020] In this embodiment, the positioning plates 9 are all arranged in an "L"-shaped structure, and a plurality of rollers 11 are installed on the inner side surface of one lateral end of the positioning plates 9 through a roller 11 bracket.
[0021] In this embodiment, the adjustment mechanism includes an adjustment block 8, a screw rod 12, a hand wheel 13 and a plurality of second sealed bearings. The cross plate 1 is provided with adjustment ports 7 on both sides of the positioning hole 17. The adjustment blocks 8 are arranged inside the adjustment ports 7. The lower ends of the adjustment blocks 8 are installed on the positioning plate 9. The insides of the adjustment blocks 8 are provided with screw rod holes passing through the adjustment blocks 8. One end of the adjustment ports 7 is provided with a mounting groove, and the other end is provided with a mounting hole. The second sealed bearings are installed in the mounting groove and the mounting hole. Both ends of the screw rod 12 are installed in the inner ring of the second sealed bearing. The middle of the screw rod 12 is threadedly connected to the screw rod hole. The opposite end faces of the screw rod 12 are extended outward and fixedly connected to the hand wheel 13. The adjustment block can be quickly driven to move by the screw rod, and the moved adjustment block can be self-locked by the screw rod after movement.
[0022] In this embodiment, positioning grooves are provided on both sides of the adjustment port 7, and positioning portions 18 are protruded on both sides of the adjustment block 8. The positioning portions 18 are slidably installed in the positioning grooves so that the adjustment block can move laterally along the positioning grooves, and the weight on the adjustment block can act on the positioning grooves and the cross plate through the positioning portions.
[0023] In this embodiment, limiting grooves 6 are provided on both sides of the drain pipe 2, and limiting parts are protruded from the inner circle surface of the positioning hole 17 opposite to the limiting groove 6. The limiting parts are slidably installed in the limiting groove 6. The drain pipe can be positioned through the limiting parts and the limiting grooves, so that the drain pipe can only move up and down along the positioning grooves, avoiding rotation and tilting, and increasing stability.
[0024] In this embodiment, a filter screen 15 is installed in the opening at the lower end of the drain pipe 2, through which the incoming accumulated water can be filtered to prevent impurities and garbage from being sucked in, thereby avoiding damage to the water pump.
[0025] When in use, the drainage pipe is inserted into the deep foundation pit, and the horizontal plate can be placed above the deep foundation pit, and the distance between the positioning plates can be adjusted according to the width of the deep foundation pit. When adjusting, the screw rod can be rotated by the hand wheel, and the rotation of the screw rod drives the adjustment block to move the adjustment block horizontally along the positioning groove. The movement of the adjustment block drives the positioning plate until the vertical end of the positioning plate is close to the inner side of the deep foundation pit opening, and the rollers on the positioning plate can be placed on the soil on both sides of the deep foundation pit. The drainage pipe can be positioned by the positioning plate and the horizontal plate to ensure stability during the pumping process;
[0026] Furthermore, when pumping water from pits at different locations, the cross plate can be pushed along the deep foundation pit, so that the rollers under the positioning plate move along the soil. The movement of the cross plate drives the drainage pipe, and the movement of the drainage pipe drives the wheels. The rolling wheels can pass through the ground at different heights. When the wheels pass through the raised ground, they can drive the drainage pipe to move upward along the positioning hole. When the wheels pass through the pits, the drainage pipe can move downward along the positioning hole, so that the lower end of the drainage pipe can be inserted into grooves of different depths, so as to ensure the quality of water pumping and reduce the residual amount of accumulated water.
[0027] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
