Description

Technical Field

[0001] The utility model belongs to the technical field of urban construction, and in particular relates to a sponge city construction drainage device. Background Art

[0002] The sponge city concept is a new urban stormwater management concept that requires cities to have the resilience of a sponge, adapting to environmental changes and responding to natural disasters. Specifically, a sponge city absorbs, stores, infiltrates, and purifies rainwater during rainfall, releasing the stored water for use when needed.

[0003] However, the existing sponge city construction drainage devices lack pre-treatment of rainwater when in use, and there are few devices for filtering rainwater, which cannot reduce the burden of subsequent rainwater treatment.

[0004] Therefore, a sponge city construction drainage device is proposed to solve the above problems. Utility Model Content

[0005] The utility model proposes a sponge city construction drainage device, which solves the problem that the sponge city construction drainage device in the related technology is insufficient in pre-treatment of rainwater when in use, has few devices for filtering rainwater, and cannot reduce the burden of subsequent treatment of rainwater.

[0006] The technical solution of the utility model is as follows: A sponge city construction drainage device comprises: a caisson and a foundation, characterized in that the inner surface of the caisson is fixedly connected to a support platform, the outer surface of the support platform is sleeved with a filter basket, and the inner surface of the filter basket is fixedly connected to a pull rod;

[0007] A partition is fixedly connected to the interior of the caisson, a guide rail is opened inside the caisson, a filter frame is slidably connected to the guide rail, and a handle is fixedly connected to the upper surface of the filter frame;

[0008] The first filter is fixedly connected to the interior of the filter frame, the second filter is fixedly connected to the interior of the filter frame, and the filter frame is inserted into the interior of the partition.

[0009] Preferably, a water inlet pipe is fixedly connected to the outer surface of the caisson, a water outlet pipe is fixedly connected to the outer surface of the caisson, and a manhole cover is inserted at the top of the caisson.

[0010] Preferably, the interior of the water outlet pipe is fixedly connected to a rotating shaft, the outer surface of the rotating shaft is sleeved with a spring, the rotation of the rotating shaft is connected to a closing leaf, and one side of the water outlet pipe is fixedly connected to a limiting ring.

[0011] Preferably, the upper surface of the foundation is fixedly connected to a cushion layer, the upper surface of the cushion layer is fixedly connected to a base layer, the upper surface of the base layer is fixedly connected to a pipe seat, the pipe seat supports the water inlet pipe and the water outlet pipe, and the bottom end of the caisson is fixedly connected to the cushion layer.

[0012] Preferably, there are two filter frames, which are arranged linearly, and the mesh number of the first filter is smaller than the mesh number of the second filter.

[0013] Preferably, the number of the springs is three and they are arranged linearly, and the springs are torsion springs.

[0014] The working principle and beneficial effects of the utility model are as follows:

[0015] Through the setting of the filter basket, the device can linearly filter out larger debris that the manhole cover cannot discharge when collecting rainwater, avoiding problems such as accidental entry into the pipe and causing pipe blockage. Through the simultaneous setting of two filter screens, when the device takes in water, it first passes through the first filter screen for filtering with a larger mesh size, and then passes through the second filter screen for further filtering. Moreover, by plugging the filter screen frame into the caisson, the filter screen can be replaced in time to avoid filter blockage, rupture, etc. caused by long-term non-update. Through the setting of the partition, the internal liquid will not seep out in large quantities during filtration, so that the filtering effect is better. Through the setting of the spring and the closing leaf, the liquid in the pipe can only flow in one direction, avoiding backflow caused by high water level and other reasons.

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Implementation Method

[0024] See also Figure 1 -5. A sponge city construction drainage device, comprising: a caisson 1 and a foundation 20. The inner surface of the caisson 1 is fixedly connected to a support platform 2. The outer surface of the support platform 2 is sleeved with a filter basket 3. The inner surface of the filter basket 3 is fixedly connected to a pull rod 4.

[0025] A partition 21 is fixedly connected to the interior of the caisson 1. A guide rail 5 is provided inside the caisson 1. A filter frame 6 is slidably connected to the guide rail 5. A handle 16 is fixedly connected to the upper surface of the filter frame 6.

[0026] The first filter 7 is fixedly connected to the interior of the filter frame 6 , the second filter 15 is fixedly connected to the interior of the filter frame 6 , and the filter frame 6 is inserted into the interior of the partition 21 .

[0027] The technical solution provided by this embodiment is: first, a deep pit is dug at a preset position. After digging to a certain depth, the foundation 20 is poured at the bottom, and then a cushion layer 19 is laid on the upper surface of the foundation 20. Then, the main body of the caisson 1 is placed on the cushion layer 19. The next step is to lay a base layer 18 on the cushion layer 19, and then install the water inlet pipe 9 and the water outlet pipe 10. After the installation is completed, the pipe seat 17 is installed according to the height and position of the water inlet pipe 9 and the water outlet pipe 10. Then, the filter frame 6 is inserted into the guide rail 5 opened inside the caisson 1. It should be noted that the filter inside the filter frame 6 should use the first filter screen 7 on the side close to the water inlet pipe 9 and the second filter screen 15 on the other side. The next step is to put the filter basket 3 into the interior of the caisson 1, and finally put the manhole cover 8 in place. During operation, rainwater After passing through the manhole cover 8, it will be simply filtered in the filter basket 4 to prevent leaves and other objects from entering the interior, and then it will enter the caisson 1, and then flow out through the water outlet 10. When flowing out, the liquid will flush the closing leaf 12 to make the flow smooth. When there is no water or drought, the closing leaf 12 will put the outlet pipe 10 in a closed state under the action of the spring 11, and the limit ring 14 will limit the closing leaf 12 to avoid excessive opening and closing. The liquid in the water inlet pipe 9 will first pass through the first filter screen 7 and the second filter screen 15 for filtration, and then be output from the outlet pipe 10. During daily maintenance, after opening the manhole cover 8, pull the pull rod 4 to pull out the filter basket 3, and then pull out the two filter frames 6 by pulling the handle 16 and replace or clean them. This device should be used in combination in series or parallel to make the effect of the device better.

[0028] Furthermore, a water inlet pipe 9 is fixedly connected to the outer surface of the caisson 1 , a water outlet pipe 10 is fixedly connected to the outer surface of the caisson 1 , and a manhole cover 8 is inserted at the top of the caisson 1 .

[0029] Specifically, by providing the water inlet pipe 9 and the water outlet pipe 10, the device can more accurately determine the cause of a channel rupture or the like when transporting water.

[0030] Furthermore, a rotating shaft 14 is fixedly connected to the inside of the water outlet pipe 10 , a spring 11 is sleeved on the outer surface of the rotating shaft 14 , and the rotation of the rotating shaft 14 is connected to the closing leaf 12 . A limiting ring 13 is fixedly connected to one side of the water outlet pipe 10 .

[0031] Specifically, the one-way valve formed by the above-mentioned arrangement can enable the device to better transport when it is working, and can relatively seal the inside of the pipeline when it is not transporting, so that the gas generated inside the pipeline does not leak out.

[0032] Furthermore, the upper surface of the foundation 20 is fixedly connected to a cushion layer 19, the upper surface of the cushion layer 19 is fixedly connected to a base layer 18, the upper surface of the base layer 18 is fixedly connected to a pipe seat 17, the pipe seat 17 supports the water inlet pipe 9 and the water outlet pipe 10, and the bottom end of the caisson 1 is fixedly connected to the cushion layer 19.

[0033] Specifically, through the multi-layer support method, the device is more stable after installation and will not be broken due to local soil erosion caused by rainwater, etc., and through the setting of the pipe seat 17, the water inlet pipe 9 and the water outlet pipe 10 are more stable.

[0034] Furthermore, there are two filter frames 6 , which are arranged linearly, and the mesh number of the first filter 7 is smaller than the mesh number of the second filter 16 .

[0035] Specifically, two layers of screens with different mesh sizes make the filtering effect and efficiency higher.

[0036] Furthermore, the number of the springs 11 is three and they are arranged linearly, and the springs 11 are torsion springs.

[0037] Specifically, the two closing leaves 12 can be closed more quickly and more tightly by using a plurality of torsion springs.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
