Description

Technical Field

[0001] The utility model belongs to the technical field of construction equipment, and particularly relates to a rainwater harvesting construction structure for a sponge city. Background Art

[0002] A sponge city refers to a city that can be as flexible as a sponge in adapting to environmental changes and coping with natural disasters brought by rainwater. When building a sponge city, it is necessary to collect rainwater. In the prior art, PP modules are usually arranged in a dug hole for water storage. Before installing the PP modules, a strip-shaped geotextile needs to be laid on the bottom and side walls of the hole. To facilitate construction, the top of the geotextile needs to be fixed.

[0003] Chinese Patent with the publication number CN215717657U discloses an installation device for an underground rainwater PP module tank. The scheme includes a first support block, a top-tightening component, an end-pressing component, and a height-adjusting component. The above scheme uses the top-tightening component to tightly press the permeable cloth against the side wall of the reservoir, and the end-pressing component is used to assist in tightly pressing one end of the permeable cloth close to the soil, facilitating the manual driving of fixing bolts.

[0004] The above scheme can be used to fix the geotextile. However, when the above scheme is used, it is necessary to manually lay the geotextile on the surface of the hole in advance, and it is necessary to continuously hold the geotextile before the top-tightening component tightly presses the geotextile to prevent the geotextile from falling into the hole. The operation is relatively cumbersome and the installation efficiency is low. Content of the Utility Model

[0005] The utility model aims to provide a rainwater harvesting construction structure for a sponge city to solve the problems of relatively cumbersome operation and low installation efficiency existing in the above scheme.

[0006] To achieve the above purpose, the utility model provides the following technical scheme:

[0007] A rainwater harvesting construction structure for a sponge city includes an extension frame and a clamping component. The extension frame has a channel that penetrates up and down, and the left and right ends of the extension frame are respectively fixedly provided with a first moving seat and a second moving seat. Lifting mechanisms are respectively arranged above the opposite sides of the first moving seat and the second moving seat. A pressing rod is arranged at the bottom of the lifting mechanism. A roller is rotatably arranged horizontally above the first moving seat, and a geotextile is wound around the roller. The clamping component is slidably arranged in the channel and can move left and right, and the clamping component is used to fix the free end of the geotextile.

[0008] The principle and effect of this technical scheme:

[0009] Stretch the stretching frame so that the first movable seat and the second movable seat at both ends of the stretching frame are placed on both sides of the top of the pit, and the two pressure bars are moved away from each other to one side close to the inner wall of the pit. In the initial state, the clamping assembly is located on the left side of the channel, and the pressure bar is located above the clamping assembly. The clamping assembly is driven to fix the free end of the geotextile, and the clamping assembly moves to the right with the free end of the geotextile. Then, the lifting mechanism is driven to lower the pressure bar so that the pressure bar continues to stretch the geotextile until the bottom of the pressure bar pushes the geotextile against the bottom wall of the pit. At this time, the fixing bolt is passed through the geotextile and inserted into the top of the pit to fix the geotextile. After cutting the geotextile at the appropriate position, the lifting mechanism is driven to drive the pressure bar to reset, and the clamping assembly is reset. Then, the first movable seat and the second movable seat are moved to transfer the stretching frame and the geotextile to the next work site, and the above operation is repeated.

[0010] Through the above arrangement, it is convenient to lay the geotextile on the surface of the pit, and the geotextile can be fixed after laying. There is no need for manual labor to continuously hold the geotextile laid on the surface of the pit, which saves human resources and improves the installation efficiency of the geotextile.

[0011] In the utility model, the extension frame includes a first mounting plate and a second mounting plate, the front and rear ends of the right side of the first mounting plate are respectively fixed with sliding rods, the front and rear ends of the left side of the second mounting plate are respectively fixed with rod sleeves, the two sliding rods are respectively slidably embedded in the corresponding rod sleeves, and enclose the channel together with the first mounting plate and the second mounting plate.

[0012] In the utility model, the clamping assembly includes a mounting block, the front and rear ends of the mounting block are respectively rotatably provided with rollers, the top of the mounting block is fixedly provided with a servo motor connected to the roller transmission, the two sliding rods are provided with a first sliding groove on the opposite side, the two rod sleeves are provided with a second sliding groove aligned with the first sliding groove on the opposite side, and the rollers are rollingly arranged in the first sliding groove and the second sliding groove.

[0013] In the utility model, the mounting block has a mounting groove that passes through the left and right sides, a through hole is opened at the top of the mounting groove, a pressure plate is slidably arranged in the mounting groove, a connecting rod that slides through the through hole is fixedly arranged on the top of the pressure plate, and a compression spring is sleeved between the pressure plate and the top wall of the mounting groove outside the connecting rod.

[0014] The principle and effect of this technical solution:

[0015] Pull the connecting rod to move the pressing plate upward to disengage from the bottom of the installation groove. The compression spring is in a compressed state and has elastic force. Pass the free end of the geotextile through the installation groove below the pressing plate. Release the connecting rod. The compression spring pushes the pressing plate to press the geotextile tightly. Drive the servo motor to drive the roller to rotate. The bottom of the roller is simultaneously in contact with the bottom walls of the first chute and the second chute, thereby driving the installation block to move along the first chute and the second chute. The end wall of the roller is in sliding contact with the inner side wall of the first chute, and the side wall of the installation block is in sliding contact with the side wall of the rod sleeve.

[0016] Through the above settings, the purpose of driving the installation block to drive the free end of the geotextile to move left and right in the channel is achieved.

[0017] In the present utility model, fixing plates are respectively and fixedly arranged above the opposite sides of the first moving seat and the second moving seat. Two convex blocks are fixedly arranged at intervals at the bottom of the fixing plate. The lifting mechanism includes a screw rod rotatably passing through the two convex blocks. A first slider is sleeved outside the screw rod in a matching manner. The top of the first slider is in sliding contact with the bottom of the fixing plate. The lifting mechanism further includes a plurality of scissor units hinged up and down. The two ends of the top of the scissor unit located at the uppermost position are respectively rotatably connected to one of the convex blocks and the first slider. One end of the top of the pressing rod is fixedly provided with a connecting block. A second slider is also slidably embedded at the top of the pressing rod. The two ends of the bottom of the scissor unit located at the lowermost position are respectively rotatably connected to the connecting block and the second slider.

[0018] The principle and effect of this technical solution:

[0019] Rotate the screw rod. Since the fixing plate restricts the rotation of the first slider, the first slider moves back and forth as the screw rod rotates. The scissor unit expands and contracts due to the change in the distance between the first slider and the convex block, so that the pressing rod moves up and down as the screw rod rotates.

[0020] Through the above settings, by rotating the screw rod to expand and contract the scissor unit, the purpose of making the pressing rod push the geotextile to tightly abut against the bottom wall of the pit and resetting the pressing rod after the installation work is completed is achieved.

[0021] In the present utility model, a cross bar is fixedly arranged between the first mounting plate and the mounting block in the front-rear direction. The two ends of the cross bar are fixedly connected to the two sliding rods.

[0022] The principle and effect of this technical solution:

[0023] Before the free end of the geotextile passes through the installation groove, make the free end of the geotextile pass through the gap between the cross bar and the first mounting plate. Through the above settings, the geotextile in the channel can be parallel to the surface of the stretching frame, which is convenient for the pressing rod to push the geotextile.

[0024] In the present utility model, two traveling wheels are rotatably arranged at the bottoms of the mutually remote sides of the first moving seat and the second moving seat.

[0025] With the above settings, it is convenient for the staff to move the first moving seat and the second moving seat, improving the practicability of the present utility model.

[0026] In the present utility model, the first mounting plate is fixedly connected to the first moving seat by bolts, and the second mounting plate is fixedly connected to the second moving seat by bolts.

[0027] Through the above settings, the first moving seat, the second moving seat and the extension frame can be separated, reducing the floor area of the present utility model when it is idle, and thus facilitating the transportation of the present utility model, further improving the practicability of the present utility model.
