Description

Technical Field

[0001] This utility model relates to the field of drainage ditch technology, specifically a drainage ditch structure. Background Technology

[0002] Drainage ditches are ditches that divert water collected in side ditches, intercepting ditches, and low-lying areas near roadbeds, farmland, and residences to areas outside the roadbed, farmland, and residences. Drainage ditches are generally laid at both ends or the lower end of slope intercepting ditches to drain surface runoff that cannot be contained by the intercepting ditches.

[0003] For example, the utility model application with application number 202221796680.9 discloses a drainage ditch structure. The drainage ditch structure similar to the above application still has the following shortcomings: during the drainage process, the water storage tank method is prone to blockage after long-term use, which will affect the normal drainage. Utility Model Content

[0004] The purpose of this utility model is to provide a drainage ditch structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drainage ditch structure, comprising a drainage ditch body, a secondary filtration assembly, and a sludge collection assembly. A drainage trough is provided on the inner side of the drainage ditch body. A perforated cover plate is installed on the upper side of the drainage ditch body, and a guide plate is fixed to the lower side of the perforated cover plate. A secondary filtration assembly is installed on one side above the guide plate, and the secondary filtration assembly includes a filter screen, a discharge port, a fixing connecting plate, a receiving box, and a water filter screen. A discharge port is provided at the guide plate below the filter screen, and fixing connecting plates are fixed at equal intervals inside the discharge port. A receiving box is fixed to the lower side of the guide plate at the discharge port, and a water filter screen is fixed to the side wall of the receiving box near the center line of the guide plate. A sludge collection assembly is installed on the inner bottom surface of the drainage ditch body.

[0006] Preferably, the bottom surface of the drainage trough has an arc-shaped structure, and the upper side of the drainage trough has an open structure.

[0007] Preferably, the guide plate has a "V" shaped structure, and the vertical center line of the guide plate coincides with the vertical center line of the hollow cover plate.

[0008] Preferably, a water trough is provided on the lower side of the middle part of the guide plate, and the water trough is a rectangular through groove.

[0009] Preferably, the filter screen has an inclined structure, and the filter screen is fixedly connected to one of the side walls of the guide plate.

[0010] Preferably, the sludge collection component includes a sludge collection frame and a portable handle. The sludge collection frame is provided in a pre-reserved groove on the bottom surface of the main body of the drainage ditch. The sludge collection frame is a rectangular frame, and a portable handle is fixed to the upper side of the sludge collection frame.

[0011] Preferably, the sludge collection assembly further includes a flow-blocking baffle and an intercepting filter screen. The flow-blocking baffle is fixed to the bottom surface of the drainage ditch body on one side of the sludge collection frame, and an intercepting filter screen is fixed to the upper side of the flow-blocking baffle.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The drainage ditch structure is equipped with a secondary filtration component. The perforated cover plate can initially intercept large impurities entering the drainage ditch. The inclined filter screen facilitates further filtration of the water flowing through the perforated cover plate. Impurities remaining on the surface of the filter screen can be concentrated and flowed to one side of the receiving box by the impact of water flow and gravity, and fall into the receiving box below through the discharge port, so that the receiving box collects the impurities. One side of the receiving box is a water filter plate, which can intercept impurities while draining the water entering the receiving box into the drainage ditch, thereby preventing a large number of impurities from entering.

[0013] The drainage ditch structure is equipped with a sludge collection component. The low-height baffle can intercept the water flow when the water flow is small, thus causing the water flowing to settle at this location. This allows impurities such as silt carried in the water to settle into the sludge collection frame. Conversely, when the water flow is large and the water level is higher than the baffle, the water flow can continue to flow through the intercepting filter screen. At this time, the intercepting filter screen can intercept impurities in the water flow, further promoting the accumulation of impurities in the sludge collection frame. The sludge collection frame can be removed for cleaning. Attached Figure Description

[0016] 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.

[0017] like Figures 1-2 As shown, this utility model provides a technical solution: a drainage ditch structure, including a drainage ditch body 1, a secondary filtration component 6, and a dirt collection component 7. A drainage trough 2 is provided on the inner side of the drainage ditch body 1. The bottom surface of the drainage trough 2 has an arc-shaped structure, and the upper side of the drainage trough 2 has an open structure. A perforated cover plate 3 is installed on the upper side of the drainage ditch body 1, and a guide plate 4 is fixed on the lower side of the perforated cover plate 3. The guide plate 4 has a "V" shaped structure, and the vertical center line of the guide plate 4 coincides with the vertical center line of the perforated cover plate 3. A drain trough 5 is provided on the lower side of the middle part of the guide plate 4, and the drain trough 5 is a rectangular through groove. The drainage trough 2 inside the drainage ditch body 1 is used for drainage. The perforated cover plate 3 can initially intercept large impurities entering the drainage trough 2. Then, the guide plate 4 with a "V" shaped structure on the lower side of the perforated cover plate 3 can guide the water flow so that the water flow is concentrated and flows into the lower drainage trough 2 through the drain trough 5 on the lower side.

[0018] like Figures 1-2 As shown, a secondary filtration assembly 6 is installed on one side above the guide plate 4. The secondary filtration assembly 6 includes a filter screen 601, a discharge port 602, a fixing connecting plate 603, a receiving box 604, and a water filter plate 605. The discharge port 602 is provided at the guide plate 4 below the filter screen 601. The fixing connecting plates 603 are fixed at equal intervals inside the discharge port 602. The receiving box 604 is fixed at the lower side of the guide plate 4 at the discharge port 602. The side wall of the receiving box 604 closest to the center line of the guide plate 4 is fixed with a water filter plate 605. The filter screen 601 has an inclined structure, and the filter... The mesh 601 is fixedly connected to one side wall of the guide plate 4; the inclined structure of the filter mesh 601 facilitates the re-filtration of water flowing through the perforated cover plate 3. Impurities remaining on the surface of the filter mesh 601 can be concentrated and flow to one side of the receiving box 604 by the impact of water flow and gravity, and fall into the lower receiving box 604 through the discharge port 602, so that the receiving box 604 collects impurities. One side of the receiving box 604 is a water filter plate 605, which can intercept impurities and discharge the water entering the receiving box 604 into the drainage trough 2, thereby avoiding the entry of a large number of impurities.

[0019] like Figures 2-3As shown, a sludge collection assembly 7 is installed on the inner bottom surface of the drainage ditch body 1. The sludge collection assembly 7 includes a sludge collection frame 701 and a portable handle 702. The sludge collection frame 701 is set in a pre-reserved groove on the bottom surface of the drainage ditch body 1, and the sludge collection frame 701 is a rectangular frame. The portable handle 702 is fixed to the upper side of the sludge collection frame 701. The sludge collection assembly 7 also includes a flow-blocking baffle 703 and an intercepting filter screen 704. The flow-blocking baffle 703 is fixed to the bottom surface of the drainage ditch body 1 on one side of the sludge collection frame 701, and the intercepting filter screen 704 is fixed to the upper side of the flow-blocking baffle 703. The flow-blocking baffle 703 is relatively short and can withstand low water flow. The water flow is intercepted, causing the water to settle at this location, allowing impurities such as silt to settle into the collection frame 701. Conversely, when the water flow is high, the water level above the flow-blocking baffle 703 can continue to flow through the intercepting filter 704. At this time, the intercepting filter 704 can intercept impurities in the water flow, further causing the impurities to accumulate in the collection frame 701. For subsequent cleaning, simply open the perforated cover 3 and the connected guide plate 4 and secondary filter assembly 6 to remove the collection frame 701 with a portable handle 702 for easy cleaning.

[0020] In summary, as Figures 1-3As shown, in use, the main body 1 of the drainage ditch can be installed with the collection frame 701 positioned upstream of the water flow. During use, the perforated cover 3 can initially intercept large impurities entering the drainage trough 2. Then, the "V"-shaped guide plate 4 on the lower side of the perforated cover 3 guides the water flow, causing it to concentrate and flow into the lower drainage trough 2 through the lower drain trough 5. During this process, the inclined filter screen 601 further filters the water flowing through the perforated cover 3. Impurities remaining on the surface of the filter screen 601 are concentrated and flow towards the receiving box 604 due to water flow impact and gravity, falling into the lower receiving box 604 through the discharge port 602. The receiving box 604 collects the impurities. A filter screen 605 on one side of the receiving box 604 intercepts impurities while simultaneously filtering out those entering the receiving box 604. Water in 04 is drained into drainage trough 2, thus preventing a large amount of impurities from entering. During use, drainage trough 2 is used for drainage. At this time, the flow-blocking baffle 703 can intercept the water flow when the water flow is small, thus causing the water flowing to this part to settle. Finally, the mud and sand and other impurities carried in the water flow settle into the inside of the dirt collection frame 701. When the water flow is large, the water level is higher than the flow-blocking baffle 703 and the water flow can continue to flow through the intercepting filter screen 704. At this time, the intercepting filter screen 704 can intercept the impurities in the water flow, further causing the impurities to accumulate in the dirt collection frame 701. During subsequent cleaning, it is only necessary to open the hollow cover plate 3 and the flow guide plate 4 and the secondary filter component 6 connected to it to take out the dirt collection frame 701 with the portable handle 702 for easy cleaning. This completes the use process of the drainage ditch structure. This is the working principle of the drainage ditch structure.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can 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.
