Sponge city drainage and dredging devices

Abstract

This utility model relates to the field of drainage and dredging, and more particularly to a drainage and dredging device for sponge cities, including a base frame and an installation cylinder; the installation cylinder is fixedly connected to the base frame. A partition plate divides the internal space of the support cylinder into two vertically distributed support spaces. A power component allows the upper and lower support spaces to exchange positions, enabling continuous sludge filtration. This avoids the problem in existing technologies where filtration equipment cannot continuously transport sludge, and the next batch of sludge can only be processed after all the sludge in the filtration equipment has been processed and removed, resulting in low sludge treatment efficiency. Simultaneously, the weight of the sludge in the upper support space after the position exchange continuously compresses the sludge in the lower support space after the position exchange, accelerating the filtration speed of water in the sludge in the lower support space and further reducing the water content in the sludge.

Description

Technical Field

[0001] This utility model relates to the field of drainage and dredging, and in particular to a drainage and dredging device for sponge cities. Background Technology

[0002] In the current process of dredging ditches, in order to prevent the dredged sludge from containing a large amount of water and affecting the transportation of the sludge, filtration equipment is usually equipped to filter the sludge and reduce the amount of water in the sludge. However, the existing filtration equipment has a limited capacity, meaning that the filtration equipment cannot continuously transport sludge during the filtration process. The next batch of sludge can only be processed after the sludge in the filtration equipment has been processed and removed, which leads to low sludge treatment efficiency. Utility Model Content

[0003] In order to overcome the shortcomings of existing technologies, such as the inability to continuously transport sludge within the filtration equipment, and the fact that the next batch of sludge can only be processed after the sludge in the filtration equipment has been completely processed and removed, resulting in low sludge treatment efficiency, this utility model provides a sponge city drainage and sludge removal device.

[0004] The technical implementation scheme of this utility model is as follows: a sponge city drainage and dredging device, including a base frame and an installation cylinder; the installation cylinder is fixedly connected to the base frame; it also includes a rotating ring, a bearing cylinder, an inlet pipe, a partition plate, an arc-shaped hollow plate, a filter screen, a water outlet pipe, and a power component; the installation cylinder is rotatably connected to two rotating rings; all rotating rings are fixedly connected to the bearing cylinder, and the bearing cylinder is in contact with the installation cylinder; the installation cylinder has a through hole, and the through hole communicates with the bearing cylinder; the installation cylinder is fixedly connected to the inlet pipe, and the inlet pipe communicates with the bearing cylinder; the bearing cylinder is slidably connected to a partition plate, which is used to divide the interior of the bearing cylinder into two vertically distributed bearing spaces; the installation cylinder is slidably connected to an arc-shaped hollow plate; the arc-shaped hollow plate is fixedly connected to a filter screen, and the filter screen is in contact with the through hole; the arc-shaped hollow plate is connected to a water outlet pipe; the installation cylinder is connected to two power components, and each power component is connected to a corresponding rotating ring, and all power components are connected to the arc-shaped hollow plate, the power components being used to drive the rotating rings and the bearing cylinder to rotate and to drive the arc-shaped hollow plate to move.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: Sponge City Drainage and Dredging Device, such as Figures 1-3As shown, it includes a base frame 1 and a mounting cylinder 2; the mounting cylinder 2 is fixedly connected to the base frame 1.

[0017] It also includes a rotating ring 3, a bearing cylinder 4, a feed pipe 5, a partition plate 6, an arc-shaped hollow plate 7, a filter screen 8, a water outlet pipe 9, and a power assembly; the mounting cylinder 2 is rotatably connected to two rotating rings 3 distributed front and rear; all rotating rings 3 are fixedly connected to the bearing cylinder 4 for holding sludge, and the bearing cylinder 4 is in contact with the mounting cylinder 2; the mounting cylinder 2 has a through hole 201, and the through hole 201 communicates with the bearing cylinder 4; the mounting cylinder 2 is fixedly connected to the feed pipe 5, and the feed pipe 5 communicates with the bearing cylinder 4; the bearing cylinder 4 is slidably connected to the partition plate 6; the mounting cylinder 2 is slidably connected to the arc-shaped hollow plate 7; the arc-shaped hollow plate 7 is fixedly connected to the filter screen 8 for intercepting sludge, and the filter screen 8 is in contact with the through hole 201; the arc-shaped hollow plate 7 is connected to the water outlet pipe 9; the mounting cylinder 2 is connected to two power assemblies distributed front and rear, and each power assembly is connected to the corresponding rotating ring 3, and all power assemblies are connected to the arc-shaped hollow plate 7.

[0018] The power assembly includes a mounting plate 111, a first motor 112, a gear 113, a gear ring 114, a second motor 115, and a connecting plate 116. The mounting cylinder 2 is bolted to the mounting plate 111. The mounting plate 111 is bolted to the first motor 112. The output shaft of the first motor 112 is fixedly connected to the gear 113. The rotating ring 3 is fixedly connected to the gear ring 114, and the gear ring 114 meshes with the gear 113. The first motor 112, the gear 113, and the gear ring 114 cooperate to drive the rotating ring 3 and the bearing cylinder 4 to rotate. The mounting plate 111 is bolted to the second motor 115. The mounting plate 111 is rotatably connected to the connecting plate 116, and the connecting plate 116 is fixedly connected to the output shaft of the second motor 115. The second motor 115 cooperates with the connecting plate 116 to drive the arc-shaped hollow plate 7 to move.

[0019] Two limiting rods 402 are provided inside the bearing cylinder 4, and all limiting rods 402 are slidably connected to the partition plate 6. The limiting rods 402 are used to make the partition plate 6 slide stably inside the bearing cylinder 4.

[0020] The feed pipe 5 is configured in the shape of a funnel, which is designed to allow the sludge to be poured into it more effectively.

[0021] The outer side of the mounting cylinder 2 is provided with a brush plate 202 for cleaning the filter screen 8.

[0022] The inner side of the mounting cylinder 2 is made of a smooth surface, and both the upper and lower ends of the bearing cylinder 4 are made of smooth surfaces. This setting is used to enable the bearing cylinder 4 to rotate better inside the mounting cylinder 2.

[0023] It should be noted in advance that the internal space of the bearing cylinder 4 will form two vertically distributed bearing spaces 401 under the separation effect of the partition plate 6. The internal space size of the bearing cylinder 4 is fixed, and the value of half of the total amount of silt can be calculated. The bucket capacity of the excavator can also be determined. Therefore, the excavation strategy can be formulated in advance based on the numerical ratio between the two. For example, by excavating a certain number of full buckets of silt, it can be determined that the bearing cylinder 4 is filled with about half of the silt.

[0024] When dredging ditches, first move the device to the ditch to be dredged, then connect one end of the external water pipe to the outlet pipe 9, and place the other end into the ditch. Place the sludge transfer cart directly under the curved hollow plate 7. Then, manually operate an excavator to dig the sludge in the ditch and pour the excavated sludge into the feed pipe 5, allowing the sludge to fall into the upper bearing space 401 through the feed pipe 5. Continue until the excavator has poured about half of the total amount of sludge that can fill the bearing cylinder 4 into the bearing space 401. Then, manually start the motor 112 using a remote control. The remote control is connected to the device's control system via Bluetooth, causing the output shaft of the motor 112 to drive the bearing cylinder 4 and the partition plate 6 to rotate 100 degrees through the gear 113, gear ring 114, and rotating ring 3 in sequence. The upper and lower bearing spaces 401 inside the bearing cylinder 4 are rotated at 80 degrees to exchange positions. During this rotation, since the bearing cylinder 4 rotates in contact with the inner wall of the mounting cylinder 2, the sludge in the upper bearing space 401 will not be poured out during the rotation. After the upper and lower bearing spaces 401 exchange positions, the sludge in the lower bearing space 401 after the exchange will be blocked by the filter screen 8 and will not be able to enter the arc-shaped hollow plate 7 through the through hole 201. The water in the sludge in the lower bearing space 401 after the exchange will be discharged from the device through the through hole 201, the filter screen 8, the arc-shaped hollow plate 7 and the water outlet pipe 9 in sequence, and will flow back into the ditch through the external water pipe to reduce the water content in the sludge in the lower bearing space 401 after the exchange.

[0025] It should be noted that after the upper and lower bearing spaces 401 exchange positions, the excavator is manually operated to pour the excavated sludge into the feed pipe 5, allowing the sludge to fall into the upper bearing space 401 after the exchange. This continues until the excavator has poured approximately half the amount of sludge that would fill the bearing cylinder 4 into the upper bearing space 401. During this process, as the amount of sludge in the upper bearing space 401 increases, the partition plate 6 will continuously move downwards within the bearing cylinder 4 due to the weight of the sludge in the upper bearing space 401. The machine moves and continuously squeezes the sludge in the lower bearing space 401 after the position is changed, thereby accelerating the filtration speed of water in the sludge in the lower bearing space 401 after the position is changed. Under this squeezing, the water content in the sludge can be further reduced. When the upper bearing space 401 after the position is changed is filled with about half of the total amount of sludge that can fill the bearing cylinder 4, the motor 2 is started manually via remote control. The output shaft of the motor 2 is then driven by the connecting plate 116 to move the arc-shaped hollow plate 7 and its connected parts clockwise on the mounting cylinder 2 from front to back, so that the filter screen 8 is moved away from the through hole 201. This prevents the filter screen 8 from intercepting the sludge in the lower bearing space 401 after the position is changed. At this time, under the weight of the sludge in the upper bearing space 401 after the position is changed, the partition plate 6 will continue to move downwards. That is, the partition plate 6 will push the sludge in the lower bearing space 401 after the position is changed to fall into the trolley through the through hole 201. When all the sludge in the lower bearing space 401 after the position is changed has fallen into the trolley, the motor 115 is restarted manually via remote control. This causes the output shaft of the motor 115 to drive the arc-shaped hollow plate 7 and its connected parts back to their initial position via the connecting plate 116. This allows the filter screen 8 to continue contacting the through hole 201. Simultaneously, the control motor 112 is restarted, causing the output shaft of the motor 112 to drive the bearing cylinder 4 and the partition plate 6 to rotate 180 degrees again through the gear 113, gear ring 114, and rotating ring 3. This causes the two bearing spaces 401 inside the bearing cylinder 4 to exchange positions again. By repeating this process, the device can continuously filter sludge, thus avoiding the problem in the prior art where the filtration equipment cannot continuously transport sludge and can only process the next batch of sludge after the sludge in the filtration equipment has been processed and removed, resulting in low sludge treatment efficiency.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
