Description

Technical Field

[0001] The utility model relates to the technical field of water supply and drainage, in particular to a drainage ditch and a drainage system. Background Art

[0002] Drainage is an important part of municipal water supply and drainage. As part of the drainage system, the main function of the drain ditch is to transform the unorganized accumulated water into organized drainage through the drain ditch, and then discharge it into the urban drainage system through the drain pipe. Existing drain ditches usually adopt the upper drainage method, that is, the upper opening of the drain ditch is used to introduce the accumulated water. In order to prevent the drain ditch from being blocked, it is usually necessary to cover the upper opening of the drain ditch with a ditch cover, and open circular, strip-shaped and other drainage holes on the ditch cover. On the one hand, it is used to guide the accumulated water to flow into the drain ditch, and on the other hand, it is used to prevent large particles of foreign matter, leaves, etc. from entering the drain ditch and causing blockage of the drain ditch. However, when foreign matter such as leaves accumulates too much, it will also cause the drainage holes on the ditch cover to be blocked, resulting in drainage difficulties. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to solve the problem that the drainage outlets of the existing drainage ditches are easily blocked, resulting in drainage difficulties, and the drainage effect is poor when the drainage volume is large. A drainage ditch and drainage system are provided, which adopt a lateral double drainage outlet structure and cooperate with a dredging mechanism to effectively increase the drainage volume and improve the drainage effect after the drainage outlet of the drainage ditch is blocked.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a drainage ditch, comprising a drainage ditch body and a cover plate arranged above the drainage ditch body, characterized in that at least one side wall of the drainage ditch body protrudes from the ground, and a plurality of first drainage outlets and second drainage outlets distributed in parallel up and down are provided on the part of the side wall protruding from the ground, wherein the first drainage outlet is located below the second drainage outlet, and a dredging mechanism is also provided on the side wall of the drainage ditch body where the first drainage outlet and the second drainage outlet are opened.

[0005] Furthermore, the dredging mechanism includes a dredging plate, one end of which is rotatably connected to the lower part of the two side walls of the first drain outlet through a rotating shaft, and the other end extends toward the outside of the drainage ditch body to form a dredging portion. In the initial state, the end of the dredging plate away from the rotating shaft is tilted downward; a water-passing mesh hole is provided on the dredging plate.

[0006] Furthermore, the dredging mechanism also includes a driving plate, which is located inside the drainage ditch body, one end of which is connected to the rotating shaft or the dredging plate, and the other end extends toward the outside of the drainage ditch body to form a driving part, through which the dredging plate can be driven to rotate around the axis of the rotating shaft; in the initial state, the end of the dredging plate away from the rotating shaft is tilted downward.

[0007] Furthermore, there is an angle between the driving plate and the dredging plate, so that in the initial state, the driving plate is in a horizontal state or the end of the driving plate away from the dredging plate is tilted downward, and there is a distance between the end of the driving plate away from the dredging plate and the bottom of the drainage ditch body.

[0008] Furthermore, the dredging mechanism also includes a guide plate, which is located in the drainage ditch body and between the first drain outlet and the second drain outlet. One end of the guide plate is connected to the side wall of the drainage ditch body, and the other end is inclined downward. The distance between the end of the guide plate away from the side wall and the side wall is smaller than the distance between the end of the driving plate away from the dredging plate and the side wall, so that the water flowing through the guide plate can act on the driving plate.

[0009] Furthermore, a driver is provided above the driving plate, which is connected to the side wall of the drainage ditch and has a driving rod extending downward. The driving rod is connected to the driving plate, and the driving plate can be driven to move up and down through the driver.

[0010] Furthermore, the upper side of the second drain port passes through the upper side of the side wall of the drain ditch body so as to extend to the bottom of the cover plate.

[0011] Furthermore, the cover plate is arranged obliquely, and the height of one side thereof close to the first drain outlet and the second drain outlet is lower than the height of the other side.

[0012] Furthermore, drainage nets are provided in both the first drain outlet and the second drain outlet, wherein the drainage nets in the first drain outlet are distributed above and below the rotating shaft, and there is a gap between the drainage nets and the rotating shaft.

[0013] A drainage system is characterized by comprising the above-mentioned drainage ditch.

[0014] Compared with the existing technology, the utility model has the following advantages: it adopts a lateral double drain outlet structure, combined with a dredging mechanism, when the external accumulated water level is low, the accumulated water can be discharged into the drainage ditch through the first drain outlet, and at this time only the first drain outlet participates in the drainage; when the external accumulated water level is high and the liquid level is higher than the second drain outlet, the second drain outlet participates in the drainage, and the first drain outlet and the second drain outlet drain at the same time, which is conducive to increasing the drainage flow.

[0015] In addition, since the first drain outlet is lower and located on the side, under normal circumstances the first drain outlet will not be blocked and the normal drainage effect can be maintained; in abnormal circumstances, such as when there is a lot of water accumulated outside, some foreign matter is washed to the first drain outlet, causing it to be blocked by foreign matter, and the external accumulated water level gradually becomes higher. When it is higher than the second drain outlet, the second drain outlet participates in drainage to ensure the normal drainage function of the drainage ditch; at the same time, the water flowing in through the second drain outlet acts on the driving plate, and the dredging plate is driven to rotate upward by the driving plate, thereby forming gaps between the blockages and between them and the ground, and then the water is drained through the water mesh holes on the dredging plate and the gaps under the dredging plate, thereby improving the drainage effect of the drainage ditch.

[0022] Example: See Figure 1 A drainage ditch comprises a drainage ditch body 1 and a cover plate 2 disposed above the drainage ditch body 1. At least one sidewall of the drainage ditch body 1 protrudes from the ground. The protruding portion of the sidewall is provided with a plurality of first and second drainage outlets 3 and 4 arranged in parallel vertically, with the first drainage outlets 3 located below the second drainage outlets 4. The cover plate 2 is a thin plate structure. When excessive water accumulates externally, the thin cover plate 2 allows the accumulated water to quickly submerge the cover plate 2. This ensures that floating objects on the liquid surface are kept away from the second drainage outlets 4, thereby preventing floating objects from clinging to and blocking the second drainage outlets 4. The first and second drainage outlets 3 and 4 are both arranged horizontally along the length of the drainage ditch body 1. In practice, the cover plate 2 is tilted, with the side closest to the first and second drainage outlets 3 and 4 being lower than the other side, thereby facilitating the diversion of water above the cover plate 2 toward the drainage outlets. The upper side of the second drain port 4 penetrates the upper side of the side wall of the drain ditch body 1 and extends to the bottom of the cover plate 2. In this way, the opening of the second drain port 4 can be maximized, which is more conducive to drainage.

[0023] This solution adopts a lateral dual-drain structure. When the external water level is low, the water can be discharged into the gutter through the first drain 3. At this time, only the first drain 3 participates in the drainage. When the external water level is high and higher than the second drain 4, the second drain 4 participates in the drainage. The first and second drains 3 and 4 drain water simultaneously, which helps to increase the drainage flow rate. In addition, the two drains are vertically distributed, with the first drain 3 located on the side, making it less likely to be completely blocked by foreign objects, and maintaining normal drainage effect. In abnormal situations, such as when there is a lot of external water, which washes some foreign objects into the first drain 3 and causes it to be blocked by foreign objects, the external water level gradually rises. When it is higher than the second drain 4, the second drain 4 participates in the drainage to ensure the normal drainage function of the gutter. This can effectively prevent drainage difficulties caused by external foreign objects such as leaves.

[0024] As an implementation method, since the first drain outlet 3 assumes the main drainage function and the second drain outlet 4 is mainly used for emergency drainage function, during construction, the opening height of the first drain outlet 3 is greater than the drainage height of the second drain outlet 4, so that the first drain outlet 3 has a sufficiently large drainage capacity and reduces the risk of the first drain outlet 3 being blocked.

[0025] A dredging mechanism is also provided on the sidewalls of the gutter body 1, defining the first and second drain outlets 3 and 4. The dredging mechanism includes a dredging plate 5, one end of which is pivotally connected to the lower portions of the two sidewalls of the first drain outlet 3 via a rotating shaft 6, and the other end of which extends outward from the gutter body 1 to form a dredging portion. Initially, the end of the dredging plate 5, away from the rotating shaft 6, tilts downward and lies flat against the ground, creating a gap between the dredging plate 5 and the ground. A water-passing mesh is provided on the dredging plate 5 to ensure that the dredging plate 5 does not block the first drain outlet 3. This allows external water to flow through the mesh to the bottom of the dredging plate 5, and then into the gutter body 1 through the first drain outlet 3 below the dredging plate 5. Furthermore, the gap between the dredging plate 5 and the ground ensures that even if foreign matter such as leaves accumulates on the dredging plate 5, the space below the dredging plate 5 will not be blocked, thereby ensuring that the first drain outlet 3 always has a certain degree of drainage capacity. During implementation, drainage nets are provided in both the first drain outlet 3 and the second drain outlet 4, wherein the drainage nets in the first drain outlet 3 are distributed above and below the rotating shaft 6, and there is a gap between the drainage nets and the rotating shaft 6, thereby blocking foreign matter and preventing foreign matter from entering the drainage ditch body 1.

[0026] The dredging mechanism also includes a drive plate 7 located inside the gutter body 1. One end of the drive plate 7 is connected to the rotating shaft 6 or the dredging plate 5, and the other end extends outward from the gutter body 1 to form a driving portion. The drive plate 7 drives the dredging plate 5 to rotate about the axis of the rotating shaft 6. In this way, the drive plate 7 and the dredging plate 5 form a lever structure. When the drive plate 7 swings up and down, the dredging plate 5 swings up and down accordingly, loosening foreign matter accumulated outside the first drain outlet 3 and helping to unclog the first drain outlet 3. In the initial state, the end of the dredging plate 5 away from the rotating shaft 6 is tilted downward and in contact with the ground. Among them, in order to avoid obstruction of water flowing into the first drain outlet 3 during the swinging process of the driving plate 7, an angle is provided between the driving plate 7 and the dredging plate 5, so that in the initial state, the driving plate 7 is in a horizontal state or the end of the driving plate 7 away from the dredging plate 5 is tilted downward, and there is a distance between the end of the driving plate 7 away from the dredging plate 5 and the bottom of the drainage ditch body 1; in this way, the driving plate 7 has sufficient swinging space and can avoid obstruction of water entering the first drain outlet 3, thereby improving the drainage effect.

[0027] As an implementation method, see Figure 1 The dredging mechanism further includes a guide plate 8, which is located within the gutter body 1 and between the first drain outlet 3 and the second drain outlet 4. One end of the guide plate 8 is connected to the side wall of the gutter body 1, and the other end is inclined downward. There is a distance between the end of the guide plate 8 away from the side wall and the driving plate 7, and the (horizontal) distance between the end of the guide plate 8 and the side wall is smaller than the (horizontal) distance between the end of the driving plate 7 away from the dredging plate 5 and the side wall, so that water flowing through the guide plate 8 can act on the driving plate 7. In this way, when the first drain outlet 3 is blocked and the external accumulated water level is higher than the second drain outlet 4, the accumulated water enters the gutter body 1 through the second drain outlet 4 and, under the guiding action of the guide plate 8, flows to the driving plate 7 and strikes the driving plate 7 downward, causing the driving plate 7 to rotate downward and driving the dredging plate 5 to rotate upward, thereby loosening foreign matter and improving the drainage effect.

[0028] In this solution, in the natural state, that is, in the state without external force, the weight ratio can be used to make the gravitational torque on the dredging plate 5 greater than the gravitational torque on the driving plate 7, so that the dredging plate 5 is tilted downward and supported on the ground, and the driving plate 7 has space to swing downward. In addition, there is a height difference between the guide plate 8 and the driving plate 7, so that the water flowing down the guide plate 8 can exert a greater impact force on the driving plate 7. The water flowing in through the second drain port 4 is guided by the guide plate 8 and then falls down to hit the driving plate 7, so that the driving plate 7 has a tendency to swing downward, and then the dredging plate 5 has a tendency to swing upward. Through continuous impact, the dredging plate 5 swings up and down or vibrates to loosen the accumulation outside the first drain port 3, thereby clearing the first drain port 3.

[0029] During implementation, the side of the drain ditch body 1 where the drain outlet is located is upright, which helps prevent foreign matter from clogging the first drain outlet 3. The other side of the drain ditch body 1 is inclined, so that the distance between the two side walls of the drain ditch body 1 gradually decreases from top to bottom. The inclined side walls help guide water within the drain ditch body 1 toward the other side, while the guide plate 8 is used to guide the water within the drain ditch body 1 toward the inclined side, thereby creating a left-right disturbance in the water flow within the drain ditch body 1. This disturbance helps to impact foreign matter attached to the outside of the first drainage network, helping to prevent the first drain outlet 3 from becoming blocked.

[0030] As another implementation method, Figure 2 A driver 9 is also provided above the drive plate 7. The driver 9 is connected to the side wall of the drain ditch and has a downwardly extending drive rod 10. The drive rod 10 is connected to the drive plate 7 and can be driven by the driver 9 to move the drive plate 7 up and down. During implementation, the drive plate 7 has a guide groove perpendicular to the side wall of the drain ditch body 1 where the drain outlet is opened. The drive rod 10 extends into the guide groove and is connected to the drive plate 7 in a sliding manner, thereby ensuring that the drive plate 7 can swing up and down. The driver 9 adopts a waterproof linear motor, hydraulic cylinder, air cylinder, etc. The drive rod 10 driven by the air moves back and forth to control the reciprocating up and down swinging of the drive plate 7, thereby driving the dredging plate 5 to swing up and down to achieve the dredging of the first drain outlet 311. During installation, the driver 9 is installed below the guide plate 8, so that the guide plate 8 can be used to block water and prevent it from being washed by the water flow entering the drain ditch body 1. This structure drives the dredging plate 5 to swing by active drive, and its dredging reliability is higher.

[0031] During implementation, the driver 9 is powered by a battery housed within the gutter body 1 or the municipal power grid. A control switch is also provided on the exterior of the gutter body 1 or on the cover plate 2 to enable on / off control as needed. As a further optimization, the control switch utilizes a (wireless) remote control, enabling remote control and more convenient operation. This solution requires the integration of electrical equipment and circuit components, resulting in a higher cost. Therefore, this gutter is suitable for specific environments with demanding drainage requirements.

[0032] The utility model also discloses a drainage system, see Figure 1 Specifically, it also includes a drainage pipe 11 or a drainage network, and the bottom and / or end of the drainage ditch are connected to the drainage pipe 11 or the drainage network, thereby forming a complete drainage system.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the present invention that do not depart from the purpose and scope of the technical solution of the present invention should be included in the scope of the claims of the present invention.
