[0006] One end of the check plate is rotatably connected to the first inner wall of the first drain pipe; the check plate includes a drainage position and a check position, and the drainage position is arranged close to the output end of the first drain pipe, and the check position is arranged close to the input end of the first drain pipe;

[0007] When the check plate rotates to the drainage position, the first drainage pipe is opened; when the check plate rotates to the non-return position, the first drainage pipe is closed;

[0009] In a possible implementation manner, one end of the limiting assembly is rotatably connected to the second inner wall; and the other end of the limiting assembly is slidably connected to the check plate.

[0010] In a possible embodiment, the limiting assembly includes a telescopically connected rotating frame and a telescopic rod; one end of the rotating frame away from the telescopic rod is rotatably connected to the second inner wall; one end of the telescopic rod away from the rotating frame is slidably connected to the check plate.

[0012] In a possible implementation manner, the sliding assembly includes a connecting shaft and two sliding blocks, and the two sliding blocks are respectively arranged at two ends of the connecting shaft; the limiting assembly is rotatably connected to the connecting shaft;

[0013] Two symmetrical limiting grooves are arranged on the side wall of the sliding groove, and the limiting grooves have the same extension direction as the sliding groove; the two sliding blocks correspond to the two limiting grooves one by one, and the two sliding blocks are respectively slidably arranged in the limiting grooves on the corresponding sides; the limiting grooves limit the sliding stroke of the sliding assembly.

[0014] In a possible implementation, a limiting portion is provided at one end of the two sliding blocks close to the connecting shaft, and the two limiting portions are respectively fitted with the side walls on the corresponding sides of the sliding groove to limit the axial movement of the sliding assembly along the connecting shaft.

[0042] Embodiment 1

[0043] A drainage structure is provided in the embodiment and can be applied to the drainage system of a municipal road; wherein the drainage structure can be arranged at the water inlet of the drainage system, and rainwater flows into the drainage system through the drainage structure, and then the rainwater is discharged into nearby rivers, lakes, seas and other water bodies through the water outlet of the drainage system.

[0044] like Figures 1 to 3 As shown, the drainage structure includes a first drainage pipe 1, a check plate 4 and a limit assembly 5. The first drainage pipe 1 can be a rectangular vertical pipe; the first drainage pipe 1 includes an input end 1a and an output end 1b connected to each other, and the output end 1b can be arranged below the input end 1a.

[0045] In use, the input end 1a is arranged close to the ground, so that rainwater can flow into the first drainage pipe 1 through the input end 1a. The output end 1b is arranged close to the ground, and the output end 1b can be used to connect to the pipeline of the drainage system, so that rainwater flows into the drainage system.

[0046] like Fig.10 and Fig.12 As shown, one end of the check plate 4 is rotatably connected to the first inner wall 102 of the first drain pipe 1 , and the other end of the check plate 4 serves as a movable end and can rotate around the connection between the check plate 4 and the first drain pipe 1 .

[0047] The check plate 4 includes a drainage position 4a and a check position 4b, wherein the drainage position 4a is arranged close to the output end 1b of the first drainage pipe 1, and the check position 4b is arranged close to the input end 1a of the first drainage pipe 1; the check position 4b is located above the drainage position 4a. It can be understood that when the check plate 4 rotates from the drainage position 4a to the check position 4b, the movable end of the check plate 4 gradually moves away from the output end 1b.

[0048] When the check plate 4 is at the drainage position 4a, the movable end of the check plate 4 is separated from the second inner wall 103 of the first drainage pipe 1, and the second inner wall 103 is arranged opposite to the first inner wall 102. Thus, the internal passage of the first drainage pipe 1 is opened, that is, the input end 1a is connected to the output end 1b; furthermore, after rainwater enters the first drainage pipe 1 through the input end 1a, it enters the pipeline of the drainage system through the output end 1b.

[0049] When the check plate 4 is in the check position 4b, the movable end of the check plate 4 abuts against the second inner wall 103 of the first drain pipe 1, so that the interior of the first drain pipe 1 is closed, that is, the passage between the input end 1a and the output end 1b is disconnected. Thus, rainwater in the drainage system can be prevented from flowing back from the output end 1b to the input end 1a, thereby preventing rainwater in the drainage system from flowing back to the road surface and causing pollution.

[0050] like Figure 4 and Figure 5 As shown, in the embodiment, the length g of the check plate 4 is equal to or slightly greater than the inner length m of the first drain pipe 1, and the width k of the check plate 4 is equal to the inner width n of the first drain pipe 1. Therefore, when the check plate 4 is in the check position 4b, the first drain pipe 1 can be completely closed. In this embodiment, the length g of the first check plate 4 is equal to the inner length m of the first drain pipe 1; when the check plate 4 is in the check position 4b, it is horizontal.

[0051] like Figure 2 and Figure 8 As shown, one end of the limit assembly 5 is connected to the second inner wall 103 of the first drain pipe 1, and the other end of the limit assembly 5 is connected to the check plate 4. The limit assembly 5 is used to limit the rotation stroke of the check plate 4 so that the check plate 4 rotates between the drainage position 4a and the check position 4b.

[0052] In the embodiment, the limit assembly 5 can limit the non-return plate 4 to rotate between the drainage position 4a and the non-return position 4b, so as to switch the function of drainage and preventing rainwater from flowing back. At the same time, the limit assembly 5 can also ensure that the non-return plate 4 can switch smoothly between the drainage position 4a and the non-return position 4b.

[0053] In the normal drainage state, rainwater enters the first drainage pipe 1 from the input end 1a. Under the impact of rainwater and the self-weight of the check plate 4, the check plate 4 rotates to the drainage position 4a, so that rainwater can smoothly pass through the first drainage pipe 1 and enter the pipeline of the drainage system. At this time, the limit assembly 5 can prevent the check plate 4 from rotating excessively and failing to smoothly return to the check position 4b.

[0054] When rainwater in the drainage system flows back, the rainwater can push the check plate 4 from the bottom to rotate away from the output end 1b, so that the check plate 4 gradually rotates to the check position 4b. At this time, the movable end of the check plate 4 abuts against the second inner wall 103 of the first drain pipe 1, thereby closing the first drain pipe 1, so that the rainwater cannot continue to flow back to the input end 1a, thereby preventing the rainwater from flowing back to the road surface. The limit assembly 5 can prevent the check plate 4 from rotating excessively and causing the inside of the first drain pipe 1 to be unclosed.

[0055] Embodiment 2

[0056] A drainage structure is provided in the embodiment. It can be understood that this embodiment is a further improvement based on the first embodiment.

[0057] like Figure 1 and Figure 2 As shown, one end of the check plate 4 is rotatably connected to the first inner wall 102 of the first drain pipe 1 through the second rotating shaft 6. Specifically, the second rotating shaft 6 passes through one end of the check plate 4 close to the first inner wall 102, and the check plate 4 is rotatable relative to the second rotating shaft 6. The second rotating shaft 6 is extended along the width direction of the check plate 4; a limit plate 601 is fixedly connected to both ends of the second rotating shaft 6 to prevent the check plate 4 from detaching from both ends of the second rotating shaft 6. The limit plate 601 is then fixedly installed on the first inner wall 102 of the first drain pipe 1. The second rotating shaft 6 and the limit plate 601 can be fixedly connected by welding, screwing or other connection methods; the limit plate 601 and the first inner wall 102 can also be fixedly connected by welding, bolting or other methods.

[0058] like Figure 2 , Figure 6 and Fig.10 As shown, one end of the limiting assembly 5 is rotatably connected to the second inner wall 103 , and the other end of the limiting assembly 5 is slidably connected to the check plate 4 .

[0059] Specifically, the limit assembly 5 includes a rotating frame 501 and two telescopic rods 502, and the two telescopic rods 502 are telescopically connected to one end of the rotating frame 501. The rotating frame 501 is U-shaped, including a first rotating shaft 501a and two first connecting rods 501b, and the two first connecting rods 501b are respectively connected to the two ends of the first rotating shaft 501a, and the two first connecting rods 501b are symmetrically arranged. In some specific embodiments, the first rotating shaft 501a and the two first connecting rods 501b are integrally arranged.

[0060] Of course, in some other embodiments, the two first connecting rods 501b and the first rotating shaft 501a can be fixedly connected by welding or screwing.

[0061] A mounting bracket 7 is fixedly mounted on the second inner wall 103 of the first drain pipe 1 , and the first rotating shaft 501 a is rotatably connected to the mounting bracket 7 , so that the limiting assembly 5 is rotatably connected to the second inner wall 103 .

[0062] Both ends of the first rotating shaft 501a are provided with a mounting hole 501c. Both ends of the inner wall of the mounting frame 7 are provided with a rotating shaft (not shown in the figure) that is matched and connected with the mounting hole 501c. Thus, the first rotating shaft 501a and the mounting frame 7 are rotatably mounted by matching the mounting hole 501c with the rotating shaft, that is, the rotating frame 501 is rotatably connected to the mounting frame 7.

[0063] In the embodiment, both first connecting rods 501b are provided with a slide groove (not shown in the figure), which is extended along the length direction of the first connecting rod 501b. One end of the slide groove extends to the end of the first connecting rod 501b away from the first rotating shaft 501a and communicates with the outside.

[0064] The two telescopic rods 502 are connected to the two first connecting rods 501 b in a one-to-one correspondence, and the connection methods are the same, and only one of them will be described.

[0065] One end of the telescopic rod 502 is limitedly connected to the slide groove of the first connecting rod 501 b, and the telescopic rod 502 can slide in the slide groove, that is, the telescopic connection between the telescopic rod 502 and the rotating frame 501 is realized.

[0066] like Figure 2 , Figure 3 , Fig.10 and Fig.12 As shown, one end of the two telescopic rods 502 away from the rotating frame 501 is slidably connected to the non-return plate 4.

[0067] Specifically, one end of the two telescopic rods 502 away from the rotating frame 501 is rotatably connected to a sliding assembly 8; the check plate 4 is provided with two sliding grooves 401, which extend along the length direction of the check plate 4, and the two sliding grooves 401 are arranged one-to-one with the two telescopic rods 502. The two sliding assemblies 8 are respectively slidably connected to the sliding grooves 401 on the corresponding sides, so that one end of the two telescopic rods 502 is slidably connected to the check plate 4.

[0068] like Figure 7 As shown, the sliding assembly 8 includes a connecting shaft 801 and two sliding blocks 802, and the two sliding blocks 802 are fixedly connected to both ends of the connecting shaft 801. Specifically, the two sliding blocks 802 can be fixedly connected to the connecting shaft 801 by screw connection, integral molding, welding, etc. One end of the telescopic rod 502 away from the rotating frame 501 is rotatably connected to the connecting shaft 801.

[0069] like Figure 3 As described above, a limiting groove 401a is provided on both opposite side walls of the sliding groove 401, and the extending direction of the limiting groove 401a is the same as the extending direction of the sliding groove 401. The two sliding blocks 802 of the sliding assembly 8 are respectively slidably provided in the limiting grooves 401a on the corresponding sides. The limiting groove 401a has two closed ends, so that the sliding stroke of the sliding block 802 in the limiting groove 401a can be limited. When the sliding block 802 slides to the closed end of the limiting groove 401a, the sliding block 802 abuts against the end of the limiting groove 401a to limit the sliding of the sliding block 802. Therefore, in the length direction of the limiting groove 401a, the sliding block 802 is prevented from being separated from the limiting groove 401a.

[0070] Furthermore, a limiting portion 803 is provided on the opposite side of the two sliding blocks 802. It can be understood that the two limiting portions 803 are respectively provided at the two ends of the connecting shaft 801. After the sliding block 802 is slidably arranged in the limiting groove 401a on the corresponding side, the corresponding limiting portion 803 abuts against the side wall of the corresponding side of the sliding groove 401, that is, the two limiting portions 803 abut against the two opposite side walls of the sliding groove 401, thereby limiting the movement of the sliding assembly 8 along the axial direction of the connecting shaft 801, that is, preventing the sliding assembly 8 from moving in the width direction of the sliding groove 401. At the same time, in the depth direction of the limiting groove 401a, the sliding block 802 is prevented from being separated from the limiting groove 401a. Thus, the telescopic rod 502 is prevented from being separated from the check plate 4.

[0071] like Figure 8As shown, a notch is provided at the position corresponding to the limit portion 803 at one end of the telescopic rod 502 close to the sliding assembly 8 to accommodate the limit portion 803. At the same time, the distance f between the top of the limit portion 803 and the end surface of the notch matches the rotation stroke of the check plate 4. That is, when the check plate 4 rotates to the check position 4b or the drainage position 4a, the telescopic rod 502 abuts against the corresponding side of the limit portion 803, thereby limiting the telescopic rod 502 from continuing to rotate, and further limiting the check plate 4 from continuing to rotate.

[0072] like Fig.10 and Fig.12 As shown, in use, when the check plate 4 gradually rotates from the check position 4b to the drainage position 4a, the check plate 4 and the limit assembly 5 gradually rotate in the direction close to the output end 1b, the sliding assembly 8 gradually slides toward the end of the sliding groove 401 away from the second rotation axis 6, and the telescopic rod 502 adapts to the telescopic length. When the check plate 4 rotates to the drainage position 4a, the sliding block 802 abuts against the end of the limit groove 401a, and the telescopic rod 502 abuts against the limit portion 803 to limit the check plate 4 from continuing to rotate. Thereby, it is prevented that the check plate 4 cannot be reset to the check position 4b due to excessive downward rotation angle under the action of backflow rainwater.

[0073] When the check plate 4 gradually rotates from the drainage position 4a to the check position 4b under the action of the backflow rainwater, the check plate 4 and the limit assembly 5 gradually rotate in the direction away from the output end 1b, and the sliding assembly 8 gradually slides toward the end of the sliding groove 401 close to the second rotation axis 6, and the telescopic rod 502 adapts to the telescopic length. When the check plate 4 rotates to the check position 4b, the sliding block 802 abuts against the end of the limit groove 401a close to the second rotation axis 6, and the telescopic rod 502 abuts against the limit portion 803, thereby limiting the check plate 4 from continuing to rotate, thereby preventing the check plate 4 from rotating excessively and causing the first drain pipe 1 to be incompletely closed.

[0074] In the embodiment, the average density of the check plate 4 is less than the density of rainwater, so that the rainwater can push the check plate 4 to rotate to the check position 4b. For example, the outer wall of the check plate 4 can be made of metal sheets such as stainless steel, and the inside thereof can be filled with materials such as foam. While the check plate 4 has a long service life, it is ensured that the check plate 4 can be smoothly pushed by rainwater and rotated to the check position 4b.

[0075] In some other embodiments, one end of the limit assembly 5 is rotatably connected to the check plate 4, and the other end of the limit assembly 5 is slidably connected to the second inner wall 103 of the first drain pipe 1, and its sliding direction is set along the depth direction of the first drain pipe 1 to achieve its up and down sliding, that is, when the limit assembly 5 slides up and down relative to the second inner wall 103, it approaches or moves away from the input end 1a of the first drain pipe 1. Specifically, one end of the limit assembly 5 can be slidably connected to the second inner wall 103 through a rotating shaft, the limit assembly 5 is rotatably connected to the rotating shaft, and the rotating shaft is slidably connected to the second inner wall 103.

[0076] like Fig. 9 As shown, in some specific embodiments, relative to the horizontal plane where the check position 4b is located, the check plate 4 can be rotated to any angle between 30° and 45° (including 30° and 45°) to the drainage position 4a, that is, the angle α between the drainage position 4a and the check position 4b can be set to any angle between 30° and 45°. This ensures that rainwater can be drained smoothly at the drainage position 4a; on the other hand, it can also ensure that the backflowing rainwater can smoothly push the check plate 4 from the check position 4b to the drainage position 4a.

[0077] In some specific embodiments, the angle α between the drainage position 4a and the non-return position 4b can be set to 30°, 35°, 45° or the like.

[0078] like Figure 1 and Figure 2 As shown, the input end 1a of the first drain pipe 1 is also provided with a first filter plate 3 for filtering rainwater to reduce debris entering the first drain pipe 1, thereby reducing debris entering the drainage system to avoid clogging the drainage system.

[0079] Specifically, a first support portion 101 is provided at the input end 1a of the first drain pipe 1, and the first support portion 101 is a step structure extending into the first drain pipe 1. A second support portion 301 is provided at the edge of the first filter plate 3, and the second support portion 301 is an outer edge structure protruding outward. The second support portion 301 is in abutment with the first support portion 101, so that the first filter plate 3 is installed at the input end 1a of the first drain pipe 1.

[0080] like Figure 1 , Figure 2 and Fig.10 As shown, in the embodiment, the drainage structure further includes a second drainage pipe 2, which is connected to the output end 1b of the first drainage pipe 1. The second drainage pipe 2 is connected to the pipeline of the drainage system, that is, the first drainage pipe 1 is connected to the pipeline of the drainage system through the second drainage pipe 2.

[0081] In some specific embodiments, the first drain pipe 1 is connected to the middle of the second drain pipe 2. The second drain pipe 2 is a horizontal pipe, and the second drain pipe 2 is vertically arranged with the first drain pipe 1. The first drain pipe 1 and the second drain pipe 2 can be fixedly connected by welding, bolting, or other connection methods.

[0082] like Figure 2 , Fig.10 and Fig.11 As shown, the drainage structure further includes a collecting component 9 for collecting debris in rainwater. The collecting component 9 is arranged at the connection between the first drainage pipe 1 and the second drainage pipe 2.

[0083] Specifically, the collection assembly 9 includes a first collection box 901 and a second collection box 902; the first collection box 901 and the second collection box 902 are connected in a floating manner, and the opening end of the second collection box 902 is arranged toward the first drain pipe 1. One end of the first collection box 901 is embedded in the output end 1b of the first drain pipe 1, so that the first collection box 901 can be limited to prevent it from shaking at will. The second collection box 902 is arranged close to the bottom of the second drain pipe 2, and the bottom of the second collection box 902 is arranged to fit the bottom of the second drain pipe 2.

[0084] A second filter plate 903 is provided on one side of the second collection box 902 close to the check plate 4, and the second filter plate 903 is used to filter the rainwater again. On the one hand, the second filter plate 903 can allow the rainwater to smoothly enter the second drain pipe 2, and then enter the pipeline of the drainage system. On the other hand, the second filter plate 903 can filter the rainwater entering the drainage system, and the debris can be trapped on the second filter plate 903 for subsequent cleaning. The size of the second filter plate 903, the size of the first collection box 901 and the output end 1b of the first drain pipe 1 are matched, so that the rainwater can enter the second drain pipe 2 after passing through the second filter plate 903. The second filter plate 903 can be fixedly installed on the first collection box 901 by welding, clamping, bolting, etc.

[0085] The second collecting box 902 is arranged below the first collecting box 901. When rainwater in the drainage system flows back to the first drainage pipe 1 through the second drainage pipe 2, when the returned rainwater passes through the second collecting box 902, debris in the returned rainwater can fall into the second collecting box 902, so that the second collecting box 902 collects the debris in the returned rainwater for subsequent cleaning.

[0086] In the embodiment, a second connecting rod 904 is fixedly connected to one side of the second filter plate 903 close to the second collecting box 902 ; a third connecting rod 906 is provided at the bottom of the second collecting box 902 , and the third connecting rod 906 is provided close to the interior of the second collecting box 902 , and the third connecting rod 906 is provided corresponding to the second connecting rod 904 .

[0089] In some other embodiments, the first plug-in portion 904a is in a slot structure, and correspondingly, the second plug-in portion 906a is in a rod structure, and the second plug-in portion 906a is inserted into the first plug-in portion 904a to achieve connection.

[0090] In the embodiment, an elastic member 905 is further provided between the second connecting rod 904 and the third connecting rod 906, one end of the elastic member 905 abuts against the first abutting portion 904b of the second connecting rod 904, and the other end of the elastic member 905 abuts against the second abutting portion 906b of the third connecting rod 906. The elastic member 905 is compressed between the first abutting portion 904b and the second abutting portion 906b, so that the elastic member 905 can push one end of the first collection box 901 to be embedded in the output end 1b of the first drain pipe 1. At the same time, under the plug-in action of the second connecting rod 904 and the third connecting rod 906, the second collection box 902 can also be limited and fixed to prevent the second collection box 902 from moving at will.

[0091] When it is necessary to clean the debris in the drainage structure, the second connecting rod 904 can be pulled to compress the elastic member 905, so that the first collection box 901 is separated from the first drainage pipe 1. This makes it convenient for the operator to clean the debris on the second filter plate 903; at the same time, it is also convenient for the operator to move the second collection box 902 and clean the debris in the second collection box 902, so as to realize centralized cleaning of the debris.

[0092] Embodiment 3

[0093] The embodiment further provides a drainage system, including the drainage structure provided in the first embodiment or the second embodiment as a water inlet of the drainage system.

[0094] The input end 1a of the first drainage pipe 1 is arranged close to the ground, and the second drainage pipe 2 is connected to the pipeline in the drainage system. When it rains, rainwater can enter the drainage structure through the input end 1a of the first drainage pipe 1, and then the drainage structure sends the rainwater to the pipeline of the drainage system, and finally discharges it to the lake, sea and other water bodies through the outlet.

[0095] When rainwater in the drainage system flows back, the check plate 4 of the drainage structure can stop the backflow of rainwater, preventing the rainwater from flowing back onto the road surface and causing pollution. At the same time, when cleaning up debris, the operator can pull the first collection box 901 close to the second collection box 902, so that the first collection box 901 and the second collection box 902 can be moved relative to the first drainage pipe 1 and the second drainage pipe 2, which is convenient for the operator to centrally clean up the debris.
