Description

Technical Field

[0001] The utility model relates to the technical field of road drainage, in particular to a drainage device. Background Art

[0002] In road engineering, it is necessary to design drainage facilities to quickly discharge surface and ground runoff, as well as various urban wastewater, to prevent road surface water from seeping into the road surface, thereby avoiding damage to the road surface structure, ensuring that the roadbed has a strong bearing capacity, extending the service life of the road, maintaining normal traffic and safety of vehicles and pedestrians, and making the road clean and hygienic.

[0003] Existing drainage devices usually have a filter screen. Water flows through the filter screen and is collected in the drainage device, and finally flows out from the outlet. A movable scraper is arranged on the surface of the filter screen to scrape off debris accumulated on the surface of the filter screen to prevent the debris from clogging the filter screen.

[0004] However, although the above solution solves the problem of filter blockage, the scraped debris will fall into the channel at the bottom of the drainage device and flow to the drainage outlet along with the water flow. On the one hand, when the scraped debris accumulates too much, it may block the drainage outlet, resulting in poor water flow. In serious cases, the road surface water cannot flow in and be discharged, affecting normal traffic; on the other hand, the debris will be discharged along with the water flow and cannot be directly reused. It is necessary to separate the debris from the water, resulting in increased drainage costs. Utility Model Content

[0043] Embodiment 1

[0044] This embodiment provides a drainage device, such as Figure 1 and Figure 2As shown, the drainage device includes a shell component 1, a water filter 2 and a cleaning component 3. Among them, the shell component 1 includes a main shell 11 and a cleaning door 12, and the main shell 11 is provided with a water inlet 111, a drainage chamber 112, a drain port (not shown in the figure), a collection chamber 114 and a cleaning port (not shown in the figure). A first barrier 116 is provided between the drainage chamber 112 and the collection chamber 114, and the drainage chamber 112 and the collection chamber 114 are completely isolated by the first barrier 116 and are not connected to each other. The drainage chamber 112 is used to collect water flow. The collection chamber 114 is used to collect debris, and can separate the water flow from the debris. The water inlet 111 is recessed in the upper surface of the main shell 11 and is connected to the drainage chamber 112. The drain port is arranged on the side wall of the drainage chamber 112, that is, the water inlet 111 is connected to the drain port through the drainage chamber 112. The accumulated water can enter the drainage chamber 112 from the water inlet 111 and be discharged from the drainage port. The water inlet 111 is also connected to the debris collecting chamber 114, and the cleaning port is arranged on the side wall of the debris collecting chamber 114, that is, the water inlet 111 is connected to the cleaning port through the debris collecting chamber 114. The cleaning door 12 can be opened and closed at the cleaning port. Opening the cleaning door 12 can not only clean the debris in the debris collecting chamber 114, but also inspect the debris collecting chamber 114. The water filter 2 is arranged between the water inlet 111 and the drainage chamber 112. Before the accumulated water enters the drainage chamber 112, it will first pass through the water filter 2 to filter the debris carried in the accumulated water, so that the debris accumulates above the water filter 2. The cleaning component 3 is arranged above the water filter 2, and the debris accumulated above the water filter 2 can be pushed into the debris collecting chamber 114, so that the debris is stored in the debris collecting chamber 114 to prevent the debris from being discharged with the water flow.

[0045] When drainage is required, the accumulated water on the road first enters the water inlet 111, and after being filtered by the water filter 2, enters the drainage chamber 112, and the debris carried in the accumulated water is blocked above the water filter 2. By setting the cleaning component 3, the debris accumulated above the water filter 2 can be pushed into the debris collection chamber 114, thereby realizing the separation of water flow and debris. The water flow flowing into the drainage chamber 112 can be discharged through the drain port, and the debris accumulated in the debris collection chamber 114 can be cleaned by opening the cleaning door 12. The drainage device separates the drainage chamber 112 and the debris collection chamber 114 by setting the first barrier 116, which can be used to collect water flow and debris respectively. The cleaning component 3 pushes the debris into the debris collecting chamber 114, and cooperates with the first blocking member 116 to separate the water flow and the debris, preventing the debris from falling into the drainage chamber 112 together with the water flow, and preventing the debris from flowing out of the drainage port at the same time as the water flow. The separated water flow does not carry the debris and can be directly recycled, which can save the process and reduce the drainage cost; and can prevent the debris from blocking the drainage port, and prevent the road from being flooded and affecting the traffic. In addition, opening the cleaning door 12 can also clean up the debris accumulated in the debris collecting chamber 114 in time, preventing the debris from rotting for a long time and polluting the environment.

[0046] Optionally, the drain outlet can be connected to a drain pipe 113 and connected to an external pumping device. The water collected in the drain chamber 112 can be pumped out by the pumping device, and the collected water can be transported to a centralized discharge location for discharge through the drain pipe 113, or transported to a recovery device for recycling. For example, in this embodiment, a stainless steel partition is selected as the first barrier 116, and a stainless steel filter is selected as the water filter 2.

[0047] Alternatively, if Figure 2 and Figure 3 As shown, the drainage device also includes a sealing assembly 4, which includes a first driving mechanism 41 and a sealing member 42. The housing of the first driving mechanism 41 is mounted on the main housing 11, and one end of the output end of the first driving mechanism 41 is connected to the housing, and the other end is in transmission connection with the sealing member 42. When drainage is not required, the sealing member 42 blocks the entrance of the impurity collecting chamber 114, and the impurity collecting chamber 114 remains sealed. When drainage is performed, the sealing member 42 still blocks the entrance of the impurity collecting chamber 114, blocking the communication between the water inlet 111 and the impurity collecting chamber 114, and preventing water from entering the impurity collecting chamber 114. When drainage is finished, the first driving mechanism 41 drives the seal 42 to move, so that the entrance of the debris collecting chamber 114 is opened, and the water inlet 111 is connected with the debris collecting chamber 114, so that the debris is pushed into the debris collecting chamber 114; when the debris is cleaned, the first driving mechanism 41 drives the seal 42 to move again, so that it blocks the entrance of the debris collecting chamber 114, blocking the connection between the water inlet 111 and the debris collecting chamber 114, so as to facilitate the next drainage. By setting the first driving mechanism 41, the opening or closing of the entrance of the debris collecting chamber 114 can be flexibly adjusted to facilitate drainage and the collection of debris, and closing the entrance of the debris collecting chamber 114 can prevent water from entering the debris collecting chamber 114, avoiding the mixing of water and debris, and the structure is simple and easy to operate.

[0048] Alternatively, if Figure 2 As shown, the drainage device also includes a connecting channel 117. The water inlet 111 and the water filter 2 are both higher than the debris collecting chamber 114, and a connecting channel 117 is set between the water inlet 111 and the debris collecting chamber 114 for communication. When cleaning the debris above the water filter 2, the cleaning component 3 pushes the debris into the connecting channel 117, and then the debris enters the debris collecting chamber 114 through the connecting channel 117. The water inlet 111 and the water filter 2 are both set higher than the debris collecting chamber 114, which is conducive to the debris being pushed and falling into the debris collecting chamber 114 under the action of gravity. By setting the connecting channel 117, the debris can be accurately collected and enter the debris collecting chamber 114.

[0049] In this embodiment, the connecting channel 117 is set as an L-shaped channel, one end of the L-shaped channel is connected to the water inlet 111, and the other end is connected to the debris collecting chamber 114. In other embodiments, the connecting channel 117 can also be set to a circular arc shape or other structural forms. The circular arc-shaped connecting channel 117 is more convenient for the passage of debris, which is not limited here.

[0050] Optionally, the outer wall of the main housing 11 is further provided with a through hole 1, and the seal 42 moves in the through hole 1. When there is no need to clean up debris, the first drive mechanism 41 drives the seal 42 to move in the through hole 1 to block the entrance of the connecting channel 117 to prevent water from entering. When cleaning up debris, the first drive mechanism 41 drives the seal 42 to open the entrance of the connecting channel 117, so that the cleaning component 3 pushes the debris into the connecting channel 117 to collect the debris.

[0051] In this embodiment, the housing of the first driving mechanism 41 is mounted on the protective cover 1 and is located inside the protective cover 1 6, and the protective cover 1 6 is mounted on the outer wall of the main housing 11. Providing the protective cover 1 6 on the outer cover of the first driving mechanism 41 can prevent it from being damaged by water flow impact.

[0052] In other embodiments, a first receiving groove may be provided in the main housing 11, and the first receiving groove is located at one side of the connecting passage 117. The housing of the first driving mechanism 41 is disposed in the first receiving groove, and the first driving mechanism 41 may drive the sealing member 42 to open or block the connecting passage 117.

[0053] Exemplarily, in this embodiment, a pneumatic cylinder or an electric cylinder is selected as the first driving mechanism 41 , and a baffle is selected as the sealing member 42 , and the surface area of ​​the baffle is larger than the cross-sectional area at the entrance of the connecting channel 117 , so as to ensure that the connecting channel 117 can be completely blocked.

[0054] Alternatively, if Figure 2 and Figure 4As shown, the cleaning assembly 3 includes a second driving mechanism 31 and a scraper 32. The housing of the second driving mechanism 31 is mounted on the main housing 11, one end of the output end of the second driving mechanism 31 is connected to the housing and can move relative to the housing of the second driving mechanism 31, and the other end is transmission-connected to the scraper 32. The scraper 32 is located above the water filter 2, and the second driving mechanism 31 can drive the scraper 32 to move along the water filter 2. When it is necessary to clean up the debris, the second driving mechanism 31 is started, and the second driving mechanism 31 drives the scraper 32 to move along the water filter 2 above the water filter 2. The scraper 32 can push the debris accumulated above the water filter 2 to move together. When the scraper 32 moves to the entrance of the debris collecting chamber 114, the debris enters the debris collecting chamber 114, thereby completing the cleaning and collection of the debris, preventing the debris from accumulating above the water filter 2 and blocking the water inlet 111, avoiding serious waterlogging on the road, and preventing the debris from falling with the water flow, blocking the drain outlet and being discharged with the water flow, so that the discharged water flow can be directly recycled. The structure is simple and the operation is convenient.

[0055] In this embodiment, a second receiving groove is provided in the main housing 11, a second through hole is provided between the second receiving groove and the water inlet 111, the housing of the second driving mechanism 31 is installed in the second receiving groove, the output end passes through the second through hole and is connected to the scraper 32, so that the scraper 32 can move above the water filter 2. The second driving mechanism 31 is arranged in the second receiving groove to avoid damage caused by water flow impact.

[0056] In other embodiments, the housing of the second driving mechanism 31 may also be mounted on the outer wall of the main housing 11. In this case, a second protective cover may be installed on the outer wall of the main housing 11, and the second driving mechanism 31 may be disposed in the second protective cover to prevent damage by water flow impact.

[0057] Exemplarily, in this embodiment, a pneumatic cylinder or an electric cylinder is selected as the second driving mechanism 31 .

[0058] Alternatively, if Figure 2 and Figure 5As shown, the drainage device also includes a purification component 5, which is arranged in the drainage chamber 112 and can be used to purify the water entering the drainage chamber 112. The purification component 5 includes a filter screen 51 and an activated carbon plate 52, and the filter screen 51 is arranged above the activated carbon plate 52 at intervals, and the filtering accuracy of the filter screen 51 is greater than the filtering accuracy of the water filter 2. When the accumulated water passes through the water filter 2, the larger debris in the accumulated water can be initially filtered, and then the water entering the drainage chamber 112 will flow through the filter screen 51 and the activated carbon plate 52 in sequence. The filtering accuracy of the filter screen 51 is greater than the filtering accuracy of the water filter 2, and the smaller impurities in the water flow can be further filtered. At this time, the water flow is filtered twice and basically does not carry impurities. The activated carbon plate 52 has strong adsorption and decolorization capabilities and is often used to purify and filter drinking water. After the water flows through the activated carbon plate 52, harmful substances (such as heavy metals) in the water can be removed, thereby ensuring that the discharged water is free of debris and harm, avoiding environmental pollution, and the discharged water can be directly used for industrial water without the need to purify the drainage again, saving processes and reducing drainage costs.

[0059] Alternatively, see Figure 5 , the two opposite inner walls of the drainage chamber 112 are provided with a limit member 53 and a support member 54, the limit member 53 is arranged above the support member 54 at intervals, and defines an insertion space between the limit member 53 and the support member 54. That is, there is an insertion space on the opposite sides of the drainage chamber 112, and both ends of the purification component 5 are inserted in the corresponding insertion space. When it is necessary to install the purification component 5, the filter screen plate 51 and the activated carbon plate 52 are arranged at intervals to form the purification component 5, and the purification component 5 is installed in the two insertion spaces, the upper surface of the filter screen plate 51 abuts against the limit member 53, and the lower surface of the activated carbon plate 52 abuts against the support member 54. The support member 54 can provide support for the purification component 5, and cooperate with the limit member 53 to limit the purification component 5 in the insertion space to prevent it from falling or moving due to the impact of water flow, thereby ensuring the water purification effect.

[0060] Alternatively, see Figure 5The purification assembly 5 also includes at least one connecting assembly 55 disposed between the filter screen plate 51 and the activated carbon plate 52, which can be used to connect the filter screen plate 51 and the activated carbon plate 52, and can also support the filter screen plate 51 so that it is spaced apart from the activated carbon plate 52. The connecting assembly 55 includes a first connecting member 551, a second connecting member 552 and a fixing member 553, wherein the first connecting member 551 includes a supporting portion 5511 and a flange portion 5512, the supporting portion 5511 is connected to the filter screen plate 51, and a flange portion 5512 is provided around one end of the supporting portion 5511 away from the filter screen plate 51. The second connecting member 552 is connected to the activated carbon plate 52 and faces the flange portion 5512, and a threaded hole is provided on the second connecting member 552. The flange portion 5512 is provided with a through hole, and the fixing member 553 can penetrate the through hole on the flange portion 5512 and be screwed into the threaded hole. The support portion 5511 is provided to increase the interval between the filter screen plate 51 and the activated carbon plate 52, which facilitates the circulation of water. The fixing member 553 is screwed into the threaded hole, which has a simple structure and is easy to operate. The fixing member 553 passes through the flange portion 5512 and is connected to the second connecting member 552, which can prevent the filter screen plate 51 and the activated carbon plate 52 from shifting horizontally, ensuring that the water flow is fully purified.

[0061] For example, in this embodiment, a bolt is selected as the fixing member 553. In other embodiments, a screw or the like can also be selected as the fixing member 553, which is not limited here.

[0062] In this embodiment, two connection components 55 are provided, which are respectively provided at the two ends of the purification component 5. In other embodiments, more than two connection components 55 may be provided between the filter screen plate 51 and the activated carbon plate 52 as required, which is not limited here. Providing multiple connection components 55 can increase the connection strength between the filter screen plate 51 and the activated carbon plate 52, and providing the connection component 55 in the middle of the filter screen plate 51 can support the filter screen plate 51 to prevent the middle thereof from collapsing.

[0063] Alternatively, if Figure 1 and Figure 2As shown, the main shell 11 is also provided with an inspection port (not shown in the figure) that allows the purification component 5 to pass through. The inspection port is connected to the drainage chamber 112. The shell assembly 1 also includes an inspection door 13, which can be opened and closed at the inspection port. When it is monitored that the water quality of the discharged water is poor, the drainage can be suspended, the inspection door 13 is opened, the original purification component 5 is taken out through the inspection port, and a new purification component 5 is installed in the drainage chamber 112, and finally the inspection door 13 is closed to drain again. By setting the inspection port and the inspection door 13, the purification component 5 can be flexibly replaced to ensure that the discharged water always has a good water quality effect, which is conducive to protecting the environment and recycling of drainage. In addition, opening the inspection door 13 can not only inspect other components, but also clean up a small amount of debris entering the drainage chamber 112 to prevent blocking the drainage port.

[0064] Alternatively, if Figure 2 As shown, a classification net disk 1141 is also provided in the debris collection chamber 114, which can filter and classify the debris entering the debris collection chamber 114. The classification net disk 1141 divides the debris collection chamber 114 into a first chamber 1142 and a second chamber 1143. The first chamber 1142 is provided above the second chamber 1143 and is connected to the water inlet 111. When cleaning the debris, the cleaning component 3 pushes the debris above the water filter 2 to first enter the first chamber 1142, and the debris falls on the classification net disk 1141 under the action of gravity. After that, the larger debris accumulates above the classification net disk 1141 and is stored in the first chamber 1142, and the smaller debris falls and is stored in the second chamber 1143. By providing the classification net disk 1141, the debris is simply classified, which is conducive to the classification and processing of the debris, reduces the processing cost, reduces unnecessary workload, and improves work efficiency.

[0065] Optionally, the cleaning door 12 includes a first door body and a second door body, the classification network disk 1141 extends to the cleaning port and separates the cleaning port into a first cleaning port and a second cleaning port, the first door body can be opened and closed at the first cleaning port, and the second door body can be opened and closed at the second cleaning port. By opening the first door body and the second door body, the sundries stored in the first chamber 1142 and the second chamber 1143 can be processed separately, which is convenient for the classification, collection and processing of the sundries. By setting the first door body and the second door body, they can be opened separately and the sundries in the corresponding chambers can be cleaned separately, which is conducive to reducing unnecessary workload and improving work efficiency.

The difference between this embodiment and the first embodiment is that Figure 2A cleaning groove 118 is provided on the main shell 11 between the cleaning port and the debris collecting chamber 114. A second barrier 119 is provided between the first chamber 1142 and the cleaning groove 118, and the second chamber 1143 is connected with the cleaning port through the cleaning groove 118. The classification net disk 1141 is rotatably provided in the second chamber 1143.
