Description

Technical Field

[0001] This utility model relates to the technical field of drainage equipment for dredging and reclamation projects, and in particular to a gate box buried pipe drainage structure and a gate box buried pipe drainage outlet system. Background Technology

[0002] During dredging and reclamation projects, overflow weir-type drainage outlets, thin-walled weir-type drainage outlets, gate box buried pipe drainage outlets, and embankment buried pipe drainage outlets are generally used for drainage. Among them, overflow weir-type and thin-walled weir-type drainage outlets have disadvantages such as high cost, complex structure, long construction period, and high site requirements. Embankment buried pipe drainage outlets have problems such as high mud loss, difficulty in control, and easy blockage of the drainage outlet. Gate box buried pipe drainage outlets are superior. For example, Chinese Patent No. CN221441422U provides a novel gate box buried pipe drainage outlet for inland river dredging construction, which includes a fixed frame. The top of the fixed frame is provided with a front gate box, an intermediate gate box, and a rear gate box. Connection openings are opened on both sides of the front gate box, the intermediate gate box, and the rear gate box. A pre-embedded pipe is provided on one side of the front gate box, and a movable cover plate is provided on one side of the rear gate box. The front gate box, the intermediate gate box, and the rear gate box are connected together by connecting pipes. This novel gate box-type buried pipe drainage outlet for inland river dredging construction connects the front, middle, and rear gate boxes in series using pre-buried and connecting pipes. This increases the drainage area above the water surface, improving drainage efficiency. It also reduces the number of drainage pipes, lowers manufacturing costs, and has lower requirements for installation site area. The movable cover allows drainage even when the cofferdam water level is lower than the outlet. However, the multiple gate boxes (front, middle, and rear) in this gate box-type buried pipe drainage outlet are all at fixed heights, making them unsuitable for cofferdam water levels of varying heights and exhibiting poor adaptability to different cofferdam water levels. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a gate box buried pipe drainage structure, which solves the problem that the gate box has a fixed height and the cofferdam has poor adaptability to water levels.

[0004] According to an embodiment of this utility model, a gate box buried pipe drainage structure includes a lower box and an upper box. The upper end of the lower box is open and the end face is recessed with an annular groove. The upper box is open at both ends and the lower end slides into the groove. The lower box is provided with a drainage hole and is also fixedly connected to a connecting pipe communicating with the drainage hole. An annular airbag is also provided in the groove to form a seal between the lower box and the upper box. The airbag is also connected to an adjusting cylinder to inflate or depress gas into the airbag. An adjusting component is also included to adjust the vertical relative position between the upper and lower boxes. The upper and lower boxes can be adjusted vertically, thereby adjusting the relative distance between their two end faces. Therefore, the height can be adaptively adjusted according to different cofferdam water levels, providing better adaptability and solving the problem of poor cofferdam water level adaptability caused by the fixed height of the gate box in the prior art.

[0005] Furthermore, the adjustment assembly includes a first support plate fixed to the inner wall of the lower housing, a fixed cylinder fixedly connected to the first support plate, a support frame fixedly connected to the upper housing, and a first adjustment rod threadedly connected to the fixed cylinder and rotatably connected to the support frame, wherein the first adjustment rod has an adjustment end located above the support frame.

[0006] Furthermore, a protective cylinder that slides around the fixed cylinder is also fixedly connected to the support frame.

[0007] Furthermore, the adjustment assembly also includes a second support plate fixed to the outer wall of the lower housing, a rotating cylinder rotatably connected to the second support plate, and a second adjustment rod telescopically connected to the rotating cylinder and parallel to the first adjustment rod. The second adjustment rod is also rotatably connected to the support frame. A first bevel gear is fixedly connected to the adjustment end, and a second bevel gear is fixedly connected to the second adjustment rod. A transmission rod is also provided between the first bevel gear and the second bevel gear. Two third bevel gears that mesh with the first bevel gear and the second bevel gear are fixedly connected to the two ends of the transmission rod, respectively.

[0008] Furthermore, a rotating wheel is fixedly connected to the outer wall of the rotating cylinder.

[0009] Furthermore, a protective cover is also provided on the support frame, and the transmission rod, as well as the first bevel gear, the second bevel gear, and the third bevel gear, are all located inside the protective cover, and both ends of the transmission rod are rotatably connected to the protective cover.

[0010] Furthermore, a sliding frame that is vertically arranged and connected to the slide groove is also provided on the outer wall of the lower box. The adjusting cylinder is fixedly connected to the upper box and can move within the sliding frame as the upper box moves.

[0011] Furthermore, an annular groove is recessed on the inner wall of the upper housing, the airbag is placed in the annular groove, and a connecting pipe is fixedly installed between the airbag and the regulating cylinder.

[0012] Furthermore, the regulating cylinder is also equipped with a piston disc and a rotating rod threaded through the piston disc. The piston disc slides against the inner wall of the regulating cylinder. The rotating rod extends to the end of the regulating cylinder away from the lower housing. A pressure gauge is also installed on the regulating cylinder between the piston disc and the connecting pipe.

[0013] According to the embodiment, a gate box buried pipe drainage outlet system is also provided, which includes multiple gate box buried pipe drainage structures as described above, and adjacent lower boxes are connected by a connecting pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The upper and lower sluice boxes can be adjusted in relative position in the vertical direction, so the relative distance between their two end faces can be adjusted. Therefore, the height can be adjusted adaptively according to different cofferdam water levels, which has better adaptability and solves the problem of poor cofferdam water level adaptability when the gate box is of fixed height in the existing technology.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0025] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] In an exemplary implementation, such as Figure 1-4 As shown, this embodiment provides a gate box buried pipe drainage outlet system.

[0027] It includes multiple gate box buried pipe drainage structures connected in sequence. Each gate box buried pipe drainage structure includes a lower box 1 and an upper box 2. The upper end of the lower box 1 is open, and an annular groove 3 is recessed at the end face. The upper box 2 is open at both ends, and its lower end slides into the groove 3. The upper box 2 can move up and down relative to the lower box 1, allowing their overall height to be adjusted. This better adapts to different cofferdam water levels, thus providing superior adaptability and solving the problem of poor cofferdam water level adaptability caused by fixed-height gate boxes in existing technologies. More specifically, the lower box 1 is provided with drainage holes 4, and is also fixedly connected to the drainage holes 4. The connecting pipe 5 allows multiple lower boxes 1 to be connected sequentially to form an integrated gate box buried pipe drainage system. Furthermore, an annular airbag 6 is provided in the chute 3 to create a seal between the lower box 1 and the upper box 2. The airbag 6 is also connected to an adjusting cylinder 7 to fill or extract gas into the airbag 6. The gate box buried pipe drainage structure also includes an adjusting component to adjust the vertical relative position between the upper box 2 and the lower box 1, that is, to adjust the overall height through the adjusting component. The airbag 6 can play a sealing role between the upper box 2 and the lower box 1 to prevent leakage.

[0028] like Figure 2-4 As shown, the adjustment assembly includes a first support plate 8 fixed to the inner wall of the lower housing 1, a fixed cylinder 9 fixedly connected to the first support plate 8, a support frame 10 fixedly connected to the upper housing 2, and a first adjustment rod 11 threadedly connected to the fixed cylinder 9 and rotatably connected to the support frame 10. The first adjustment rod 11 has an adjustment end 12 located above the support frame 10. The first support plate 8 provides a stable adjustment support base inside the lower housing 1. The fixed cylinder 9 is fixed to the first support plate 8, so that the adjustment end 12 of the first adjustment rod 11 can be rotated close to the support. This allows the first adjusting rod 11 to rotate upwards / downwards relative to the first support plate 8. The first adjusting rod 11 and the support frame 10 rotate relative to each other, and the support frame 10 can move upwards / downwards as it rotates, ultimately causing the upper box 2 to move upwards / downwards relative to the lower box 1, thus adjusting the overall height. Furthermore, a protective cylinder 13 is fixedly connected to the support frame 10 and slides around the fixed cylinder 9. The protective cylinder 13 is fitted around the first adjusting rod 11 and moves with the support frame 10, providing protection for the first adjusting rod 11.

[0029] Furthermore, such as Figure 1-6As shown, the adjustment assembly also includes a second support plate 14 fixed to the outer wall of the lower housing 1, a rotating cylinder 15 rotatably connected to the second support plate 14, and a second adjustment rod 16 telescopically connected to the rotating cylinder 15 and parallel to the first adjustment rod 11. The second adjustment rod 16 is also rotatably connected to the support frame 10. A first bevel gear 17 is fixedly connected to the adjustment end 12, and a second bevel gear 18 is fixedly connected to the second adjustment rod 16. A transmission rod 19 is also provided between the first bevel gear 17 and the second bevel gear 18. Two third bevel gears 20 that mesh with the first bevel gear 17 and the second bevel gear 18 are fixedly connected to the two ends of the transmission rod 19, respectively. The second support plate 14 provides a rotating support base outside the lower housing 1. When adjusting the overall height, rotating the rotating cylinder 15 can move the corresponding second adjustment rod 16 up / down (a guide bar 21 is fixedly connected to the second adjustment rod 16, and a guide groove is recessed on the inner wall of the rotating cylinder 15 for the guide bar 21 to slide). During operation, the second adjusting rod 16 rotates synchronously with the rotating cylinder 15, and also drives the second bevel gear 18 to rotate forward / reverse. Then, the third bevel gear 20 causes the transmission rod 19 to rotate, and finally, the third bevel gear 20 and the first bevel gear 17 cause the adjusting end 12 to rotate, thus realizing the movement adjustment of the support frame 10, so that the upper box 2 can be moved relative to the lower box 1. This allows for easy adjustment from the outside. Furthermore, a rotating wheel 22 can be fixedly connected to the outer wall of the rotating cylinder 15 to facilitate the rotation of the rotating cylinder 15, making the adjustment more convenient. More specifically, a protective cover 23 can be set on the support frame 10, so that the transmission rod 19, the first bevel gear 17, the second bevel gear 18 and the third bevel gear 20 are all located inside the protective cover 23, providing them with protection. At the same time, both ends of the transmission rod 19 are fixedly passed through the corresponding third bevel gear 20 and rotatably connected to the inner wall of the protective cover 23.

[0030] like Figure 3 and 4As shown in the detailed scheme, a sliding frame 24, which is vertically arranged and communicates with the slide groove 3, is also provided on the outer wall of the lower housing 1. The adjusting cylinder 7 is fixedly connected to the upper housing 2 and moves with the upper housing 2. The adjusting cylinder 7 can move within the sliding frame 24. When the adjusting cylinder 7 is fixed on the upper housing 2 and moves with the upper housing 2, the sliding frame 24 provided on the lower housing 1 provides space so that the movement and adjustment are not affected. More specifically, an annular groove 25 is recessed on the inner wall of the upper housing 2. The airbag 6 is placed in the annular groove 25 and between the airbag 6 and the adjusting cylinder 7. A connecting pipe 26 is fixedly installed, and an annular groove 25 provides a space for the airbag 6 to be accommodated. During adjustment, the gas inside the airbag 6 can be released first, reducing its volume. This reduces friction during movement, thus extending its service life. After adjustment, the airbag 6 is refilled with gas, restoring it to its inflated state and filling the annular groove 25 for a sealing effect. Furthermore, the airbag 6 and annular groove 25 can be two or more sets, depending on the specific requirements. The specific choice depends on the situation; more specifically, the regulating cylinder 7 is also equipped with a piston disc 27 and a rotating rod 28 threaded through the piston disc 27. The piston disc 27 is slidably fitted with the inner wall of the regulating cylinder 7. The rotating rod 28 extends to the end of the regulating cylinder 7 away from the lower housing 1. A pressure gauge 29 is also installed on the regulating cylinder 7 between the piston disc 27 and the connecting pipe 26. The end of the rotating rod 28 outside the regulating cylinder 7 can also be connected to a handwheel 30 for easy rotation of the rotating rod 28. The rotating rod 28 and the piston disc 27 are... It is threaded, so the piston disc 27 can move inside the adjusting cylinder 7 as it rotates (more specifically, a rod that cooperates with the piston disc 27 can also be set inside the adjusting cylinder 7, so that the piston disc 27 can move laterally under the guidance of the guide rod 31). The airbag 6 can be evacuated / inflated through the connecting pipe 26, and the pressure gauge 29 can detect the air pressure in the adjusting cylinder 7 and the airbag 6 to prevent leakage and sealing failure (an inflation nozzle can also be connected to the adjusting cylinder 7 to fill the airbag 6 and the adjusting cylinder 7 with gas to maintain the air pressure).
