Description

Technical Field

[0001] The utility model relates to the field of drainage, and in particular to a drainage facility with the functions of both settling and intercepting floating objects. Background Art

[0002] The in-plant drainage system refers to the drainage system designed inside the factory or production facility to effectively remove liquid waste such as rainwater. The in-plant drainage system generally uses open rainwater ditches and is equipped with an initial rainwater sedimentation tank. Most of the rainwater inside the factory is mixed with only a small amount of dust or other small solid particles. The external drainage system of the factory area must not only consider rainwater but also flood control. When rainwater flows through mountains and villages, it not only carries a lot of silt, but also often contains a lot of floating objects such as branches and domestic garbage. These silt and floating objects accumulate in the drainage system for a long time and block the drainage pipes.

[0003] At present, in order to solve the problem of drainage pipe blockage, the external drainage system is usually set to have a larger drainage flow, usually using large-diameter culverts or drainage ditches. However, as time goes by, floating objects and silt gradually accumulate and still block the drainage system. In particular, drainage systems such as culverts, once blocked, are very likely to cause water accumulation upstream and are also very difficult to clean. Utility Model Content

[0004] The utility model aims to provide a drainage facility with the functions of settling mud and sand and intercepting floating objects. The drainage facility with the functions of settling mud and sand and intercepting floating objects has a sedimentation tank and an interception net, which can effectively filter the mud and sand and floating objects in the drainage system, thus solving the problem of drainage system blockage.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a drainage facility with the function of settling mud and sand and intercepting floating objects, the drainage facility with the function of settling mud and sand and intercepting floating objects comprises a sedimentation tank, an inlet pipe and an outlet pipe respectively connected to the two ends of the sedimentation tank, a retaining wall is arranged in the sedimentation tank, the two ends of the retaining wall are respectively connected to the inner walls of the two sides of the sedimentation tank, the retaining wall comprises a high-height guide wall and a low-height overturning wall, the height of the guide wall is not lower than the lowest point of the inlet pipe, the height of the overturning wall is lower than the lowest point of the outlet pipe, and the guide wall is arranged at a position far away from the inlet pipe;

[0006] The water inlet pipe and the water outlet pipe are connected to the upper part of the sedimentation tank;

[0007] The water outlet pipe is arranged to be inclined downward, the connection between the water outlet pipe and the sedimentation tank is arranged as the highest position of the water outlet pipe, and an interception grille is arranged at the lowest point of the water outlet pipe.

[0008] Preferably, the retaining wall is provided in plurality, and the plurality of retaining walls are arranged side by side along the length direction of the sedimentation tank;

[0009] The guide wall is arranged opposite to the water-turning wall adjacent to the retaining wall.

[0010] Preferably, the length of the guide wall is greater than the length of the overflow wall.

[0011] Preferably, the retaining wall is configured to be tapered, and the thickness of the retaining wall decreases as the height of the retaining wall increases.

[0012] Preferably, the water inlet pipe is arranged to be inclined downward, and the connection between the water inlet pipe and the sedimentation tank is set as the lowest position of the water inlet pipe.

[0013] Preferably, the bottom of the sedimentation tank is provided with a slope, and the height of the end where the water inlet pipe of the sedimentation tank is located is higher than the height of the end where the water outlet pipe is located.

[0014] Preferably, the water outlet pipe is detachably connected to the intercepting grid.

[0015] Preferably, two opposite installation grooves are provided at the end of the water outlet pipe, and the intercepting grille cooperates with the installation grooves.

[0016] Preferably, the drainage facility having the functions of settling mud and sand and intercepting floating objects is provided with a maintenance platform along the outer edge of the top of the sedimentation tank.

[0017] Preferably, the drainage facility having the functions of settling mud and sand and intercepting floating objects further comprises a water pump, and the water pump is arranged between the outlet pipe and the retaining wall closest to the outlet pipe.

[0018] According to the above technical solution, the water inlet pipe of the utility model introduces rainwater into the sedimentation tank. After entering the sedimentation tank, the rainwater continues to move forward and will encounter a high diversion wall and be blocked by the diversion wall. Under the action of the diversion wall, the flow speed of the rainwater slows down. At this time, the mud and sand carried by the rainwater begin to settle. As more and more rainwater flows into the sedimentation tank, the water level blocked by the retaining wall gradually rises until the water level rises to the position of the overflow wall. The water inlet pipe continues to take in water, and the water will flow over the overflow wall into the rear part of the sedimentation tank.

[0019] After the rainwater flows into the sedimentation tank through the water inlet pipe, its flow rate will be slowed down due to the obstruction of the diversion wall, so that the mud and sand in front of the retaining wall have the opportunity to settle in the sedimentation tank. Under the action of the water-turning wall, the water and mud and sand at the bottom of the sedimentation tank cannot continue to flow forward, so the mud and sand at this position have the opportunity to settle in the sedimentation tank, thereby achieving the purpose of settling the mud and sand in the rainwater. The rainwater that flows over the water-turning wall into the rear of the sedimentation tank flows more slowly, making the rainwater at the rear of the sedimentation tank flow more smoothly, so the effect of settling the mud and sand in the water in the sedimentation tank is better. Therefore, the water above the sedimentation tank contains less mud and sand, so the water flow in the outlet pipe at the top of the sedimentation tank contains less mud and sand, which can significantly reduce the risk of culvert blockage.

[0020] The height of the diversion wall is not lower than the lowest point of the water inlet pipe, so that the diversion wall can fully block the rainwater flowing in from the water inlet pipe, thereby achieving effective deceleration of the rainwater.

[0021] The height of the water-turning wall is lower than the lowest point of the water outlet pipe, so that the rainwater in the sedimentation tank can flow fully and avoid too much rainwater remaining in front of the sedimentation tank. Preferably, the height of the water-turning wall is set to be no higher than 50 cm.

[0022] The outlet pipe is tilted downward to allow rainwater in the outlet pipe to flow more smoothly, and floating objects on the water surface can flow continuously from the sedimentation tank into the outlet pipe along with the water flow, and eventually accumulate in front of the interception grille.

[0023] Preferably, the water outlet pipe is configured to have a certain length, and the upper end of the water outlet pipe is open, so that there is enough space in the water outlet pipe to accommodate these floating objects, and these floating objects can be easily salvaged through the opening opened at the top.

[0024] Other features and advantages of the present invention will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0039] In the present utility model, unless otherwise stated, directional words such as "away from, above, side by side, opposite, outer edge" contained in the terms merely represent the orientation of the terms in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the terms.

[0040] A drainage facility with the function of settling mud and sand and intercepting floating objects, the drainage facility with the function of settling mud and sand and intercepting floating objects comprises a sedimentation tank 1, an inlet pipe 2 and an outlet pipe 3 respectively connected to the two ends of the sedimentation tank 1, a retaining wall is arranged in the sedimentation tank 1, the two ends of the retaining wall are respectively connected to the inner walls of the two sides of the sedimentation tank 1, the retaining wall comprises a high-height guide wall 41 and a low-height overturning wall 42, the height of the guide wall 41 is not lower than the lowest point of the inlet pipe 2, the height of the overturning wall 42 is lower than the lowest point of the outlet pipe 3, and the guide wall 41 is arranged at a position far away from the inlet pipe 2;

[0041] The water inlet pipe 2 and the water outlet pipe 3 are connected to the upper part of the sedimentation tank 1;

[0042] The outlet pipe 3 is arranged to be inclined downward, and the connection between the outlet pipe 3 and the sedimentation tank 1 is arranged as the highest position of the outlet pipe 3 , and an interception grille 43 is arranged at the lowest point of the outlet pipe 3 .

[0043] Through the implementation of the above technical solution, the water inlet pipe 2 introduces rainwater into the sedimentation tank 1. After entering the sedimentation tank 1, the rainwater continues to move forward and encounters the high diversion wall 41 and is blocked by the diversion wall 41. Under the action of the diversion wall 41, the flow speed of the rainwater slows down. At this time, the mud and sand carried by the rainwater begin to settle. As more and more rainwater flows into the sedimentation tank 1, the water level blocked by the retaining wall gradually rises until the water level rises to the position of the overflow wall 42. The water inlet pipe 2 continues to take in water, and the water will flow over the overflow wall 42 into the rear part of the sedimentation tank 1.

[0044] After the rainwater flowing in through the water inlet pipe 2 enters the sedimentation tank 1, due to the obstruction of the guide wall 41, its flow rate will be slowed down, so that the mud and sand in front of the retaining wall have the opportunity to settle in the sedimentation tank 1. Under the action of the water-turning wall 42, the water and mud and sand at the bottom of the sedimentation tank 1 cannot continue to flow forward, so the mud and sand at this position have the opportunity to settle in the sedimentation tank 1, thereby achieving the purpose of settling the mud and sand in the rainwater. The flow rate of the rainwater that flows over the water-turning wall 42 into the rear part of the sedimentation tank 1 is slower, so that the rainwater at the rear part of the sedimentation tank 1 flows more steadily, so the effect of settling the mud and sand in the water in the sedimentation tank 1 is better, so the mud and sand content in the water above the sedimentation tank 1 is less, so the mud and sand content in the water flow in the outlet pipe 3 located at the upper part of the sedimentation tank 1 is less, so the risk of the culvert 10 being blocked can be significantly reduced.

[0045] The height of the guide wall 41 is not lower than the lowest point of the water inlet pipe 2 , so that the guide wall 41 can fully block the rainwater flowing in from the water inlet pipe 2 , thereby achieving effective deceleration of the rainwater.

[0046] The height of the water-turning wall 42 is lower than the lowest point of the water outlet pipe 3, so that the rainwater in the sedimentation tank 1 can flow fully and avoid a lot of rainwater remaining in front of the sedimentation tank 1. Preferably, the height of the water-turning wall 42 is set to be no higher than 50 cm.

[0047] The outlet pipe 3 is tilted downward so that rainwater in the outlet pipe 3 flows more smoothly, and floating objects on the water surface can flow into the outlet pipe 3 from the sedimentation tank 1 along with the water flow, and finally accumulate in front of the interception grid 43.

[0048] Preferably, the water outlet pipe 3 is configured to have a certain length, and the upper end of the water outlet pipe 3 is open, so that there is enough space in the water outlet pipe 3 to accommodate these floating objects, and these floating objects can be easily salvaged through the opening opened at the top.

[0049] In this embodiment, preferably, a plurality of retaining walls are provided, and the plurality of retaining walls are arranged side by side along the length direction of the sedimentation tank 1;

[0050] The guide wall 41 is arranged opposite to the overflow wall 42 of the adjacent retaining wall.

[0051] The guide wall 41 and the overflow wall 42 of the adjacent retaining wall are arranged relative to each other so that the rainwater in the sedimentation tank 1 needs to flow in a circuitous manner in the sedimentation tank 1 before entering the outlet pipe 3, which is beneficial to the deceleration of the water flow, making the water flow in the sedimentation tank 1 more stable, and achieving a better sedimentation effect, which is beneficial to reducing the mud and sand content in the outlet pipe 3.

[0052] In this embodiment, preferably, the length of the guide wall 41 is greater than the length of the overflow wall 42 .

[0053] The length of the guide wall 41 is greater than that of the overflow wall 42, so that the overflow walls 42 of two adjacent retaining walls will not overlap, that is, the water flow in the sedimentation tank 1 cannot directly flow in from the previous overflow wall 42 and then flow out through the next overflow wall 42. All rainwater must flow in a circuitous manner in the sedimentation tank 1, which significantly reduces the flow rate of rainwater. At the same time, it also makes the water flow in the sedimentation tank 1 more stable, which is conducive to the sedimentation of mud and sand.

[0054] In this embodiment, preferably, the retaining wall is configured to be tapered, and the thickness of the retaining wall decreases as the height of the retaining wall increases.

[0055] The closer the retaining wall is to the bottom of the sedimentation tank 1, the greater the rain pressure it is subjected to. Therefore, from the perspective of structural strength, the retaining wall is set to be conical, and the thickness of the retaining wall is greater the closer it is to the bottom of the sedimentation tank 1, so that the strength of the retaining wall can meet the use requirements.

[0056] In this embodiment, preferably, the water inlet pipe 2 is arranged to be inclined downward, and the connection between the water inlet pipe 2 and the sedimentation tank 1 is set as the lowest position of the water inlet pipe 2.

[0057] The water inlet pipe 2 is tilted downward to make the drainage in the factory smoother.

[0058] In this embodiment, preferably, the bottom of the sedimentation tank 1 is provided with a slope, and the height of the end where the water inlet pipe 2 of the sedimentation tank 1 is located is higher than the height of the end where the water outlet pipe 3 is located.

[0059] The bottom of the sedimentation tank 1 is configured to have a certain slope so that the bottom of the sedimentation tank 1 is inclined toward the outlet pipe 3. Rainwater and mud in the sedimentation tank 1 tend to flow toward the outlet pipe 3 under the action of gravity, thereby achieving the aggregation effect of the sedimentation tank on rainwater and mud.

[0060] The collection of rainwater by the sedimentation tank 1 can make the rainwater that has not been discharged in the sedimentation tank 1 gather in the space closest to the outlet pipe 3, which is convenient for cleaning the rainwater in the sedimentation tank at a later time.

[0061] The sedimentation tank 1 gathers mud and sand so that the mud and sand in the sedimentation tank 1 are gathered in the space closest to the outlet pipe 3, which is convenient for cleaning the mud and sand in the sedimentation tank at a later time.

[0062] In this embodiment, preferably, the water outlet pipe 3 is detachably connected to the interception grid 43 .

[0063] The intercepting grille 43 may be blocked if used for a long time. The water outlet pipe 3 is detachably connected to the intercepting grille 43 so that the intercepting grille 43 can be easily disassembled. After the intercepting grille 43 is disassembled, the intercepting grille 43 can be easily cleaned.

[0064] In this embodiment, preferably, two opposite installation grooves 31 are provided at the end of the water outlet pipe 3 , and the interception grille 43 matches with the installation grooves 31 .

[0065] After the outer frame of the intercepting grille 43 is inserted into the mounting groove 31 , it can be matched with the mounting groove 31 , so that the mounting groove 31 can be relatively fixed with the water outlet pipe 3 .

[0066] When the intercepting grille 43 needs to be removed, the intercepting grille 43 only needs to be pulled out from the mounting groove 31 .

[0067] In this embodiment, preferably, the drainage facility having the functions of settling mud and sand and intercepting floating objects is provided with an inspection platform 51 along the outer edge of the top of the sedimentation tank 1 .

[0068] The maintenance platform 51 facilitates operators to perform operations such as cleaning the sedimentation tank 1 .

[0069] The top of the sedimentation tank 1 is set as an open structure to facilitate operators to clean the sedimentation tank 1.

[0070] In this embodiment, preferably, the drainage facility having the function of settling mud and sand and intercepting floating objects further includes a water pump, and the water pump is arranged between the outlet pipe 3 and the retaining wall closest to the outlet pipe 3 .

[0071] A water pump is provided to pump out the rainwater that is not discharged from the sedimentation tank 1, and the rainwater can be used to irrigate the green areas within the plant area.

[0072] After the rainwater is discharged, the sedimentation tank 1 can be cleaned. Since a slope is arranged at the bottom of the sedimentation tank 1, mud and sand are more likely to gather in the sedimentation tank 1 near the outlet pipe 3, so the sedimentation tank 1 can be cleaned very conveniently.

[0073] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0074] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0075] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
