Description

Technical Field

[0001] This application relates to the field of municipal road drainage equipment technology, specifically to a high-efficiency drainage device for municipal roads. Background Technology

[0002] In municipal road drainage systems, the smooth flow of sewers directly impacts the normal operation of a city. Existing municipal road drainage systems have several shortcomings. On the one hand, sewers are easily clogged by various debris, such as leaves and garbage. Traditional systems lack effective methods for handling this debris, leading to poor drainage and even urban flooding. On the other hand, existing systems have low drainage efficiency and cannot quickly drain water when demand is high. Furthermore, the specifications of sewers may vary in different road sections, and many traditional systems are ill-suited to these differences, exhibiting poor versatility. These problems severely affect the effectiveness of municipal road drainage systems, thus necessitating a drainage system that can effectively handle debris, improve drainage efficiency, and adapt to different sewer specifications. Summary of the Invention

[0003] In response to the aforementioned technical problems, this application addresses the issues of municipal road sewers being easily clogged by debris during drainage, as well as low drainage efficiency, and the difficulty of existing devices effectively handling sewers of different specifications and achieving efficient dredging and drainage.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: a high-efficiency drainage device for municipal roads, comprising a support cylinder, an inner rod and a limiting ring on the support cylinder, a plurality of conveying plates and a stirring rod fixedly mounted on the inner rod, the plurality of conveying plates being spirally arranged on the inner rod, the conveying plates being provided with blades, a support plate fixedly mounted on the support cylinder, a support rod slidably mounted on the support plate, a connecting block mounted on the support rod, a telescopic rod rotatably mounted on the connecting block, a movable ring rotatably mounted on one end of the telescopic rod near the support cylinder, the movable ring being sleeved on the support cylinder.

[0005] To better realize this application, the conveyor plate is further described as a spiral plate structure with an arc.

[0006] To better realize this application, the support rod further includes multiple secondary rods, each secondary rod consisting of a slide rod, an inner connector, and an outer connector. The secondary rods are slidably mounted on the support plate, and the slide rod slides on the support plate. The inner connector and the outer connector are located at the ends of the slide rod, respectively. The inner connector is provided with an external thread groove, and the outer connector is provided with an internal thread.

[0007] To better realize this application, the inner connector is further provided with a contact head, which is made of a flexible material.

[0008] To better realize this application, the telescopic rod further includes an inner telescopic rod, an outer telescopic rod, and a spring. The end of the inner telescopic rod near the moving ring is rotatably connected to the moving ring. The spring is sleeved on the inner telescopic rod, and the outer telescopic rod is sleeved on the spring. The two ends of the spring are fixedly connected to the end of the inner telescopic rod away from the moving ring and the end of the outer telescopic rod away from the support rod, respectively. The end of the outer telescopic rod near the support rod is rotatably connected to the connecting block on the support rod.

[0009] To better realize this application, the movable ring is further provided with multiple threaded plates, the threaded plates are provided with external threaded grooves, the limiting ring is provided with internal threads, the limiting ring and the threaded plates are threadedly engaged, the threaded plates have a certain elasticity, and the installation radius of the threaded plates is greater than the inner diameter of the limiting ring.

[0010] The technical solution provided in this application has the following advantages compared with the prior art:

[0011] 1. This application uses a unique fixing structure, in which the sliding ring slides down to drive the telescopic rod to push the support rod against the inner wall of the sewer, and the spring force is used to maintain the contact effect, which can stably fix the device in the sewer and prevent the device from falling off due to the impact of water flow during drainage, thus solving the problem of existing devices not being firmly fixed in the sewer.

[0012] 2: This application is equipped with a spiral conveyor plate with blades and an agitator rod, which can agitate and cut debris in the sewer, change the size of the debris, and prevent it from clogging the sewer. This effectively solves the problem of sewers being easily clogged by debris and ensures smooth drainage.

[0013] 3: This application allows manual control of the inner rod's forward and reverse rotation. When rotating forward, the conveyor plate drives the water flow, increasing the impact of the water flow on the blockage to clear the sewer. When rotating in reverse, the debris moves in the opposite direction of drainage, alleviating the blockage and flexibly addressing sewer blockage problems, thus improving clearing efficiency.

[0014] 4: The support rod of this application consists of multiple telescopic auxiliary rods, and the length can be adjusted by the threaded connection of the inner and outer connectors, which can adapt to different specifications of sewer inner diameter and enhance the versatility of the device.

[0015] 5: This application provides a threaded plate on the moving ring that cooperates with the limiting ring. By rotating the limiting ring, the contact area between the threaded plate and the support cylinder can be increased, the friction can be improved, the position of the moving ring can be further fixed, and the stability of the device in the sewer can be ensured.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] like Figures 1 to 5 As shown, a high-efficiency drainage device for municipal roads includes a support cylinder 101. An inner rod 102 is fixedly installed on the support cylinder 101. A plurality of conveying plates 103 and an agitator rod 104 are fixedly installed on the inner rod 102. The plurality of conveying plates 103 are spirally arranged on the inner rod 102 and are equipped with blades. A support plate 105 is fixedly installed on the support cylinder 101. A support rod 106 is slidably installed on the support plate 105. A connecting block is provided on the support rod 106. A telescopic rod 107 is rotatably installed on the connecting block. A movable ring 108 is rotatably installed at one end of the telescopic rod 107 near the support cylinder 101. The movable ring 108 is sleeved on the support cylinder 101.

[0025] In use, the device of this application is placed in the sewer. By controlling the moving ring 108 to slide downward on the support cylinder 101, the moving ring 108 pushes the upper end of the telescopic rod 107, and then the lower end of the telescopic rod 107 pushes the support rod 106 to move away from the support cylinder 101 on the 05, that is, towards the inner wall of the sewer. Thus, the device of this application is fixed by the tight fit between the support rod 106 and the inner wall, so as to prevent the device of this application from falling off due to the impact of the water flow when draining.

[0026] In use, the operator manually controls the rotating ring at the upper end of the inner rod 102 to drive the inner rod 102, which in turn drives the conveying plate 103 and the agitating rod 104 at the lower end of the inner rod 102. The agitating rod 104 stirs up debris in the sewer, thus preventing blockage. The blades on the conveying plate 103 cut the debris, changing its size to prevent it from becoming too large and causing blockage. The inner rod 102 can also be manually controlled to rotate in the opposite direction, causing the agitating rod 104 to move some debris in the opposite direction of drainage, thereby reducing the amount of blockage in the sewer. Under the gravity and impact of the water flow, the reduced amount of blockage can be cleared. Then, the inner rod 102 is released, and the water flow drives the conveying plate 103 to rotate, conveying the blockage downwards.

[0027] A connecting block is provided on the inner rod 102, which can be connected to an external power source, such as an electric drill, to directly control the powerful rotation of the inner rod 102. This allows the spiral structure of the conveyor plate 103 to actively drive the water flow. When the water flow is controlled to move in the opposite direction to the drainage direction, a negative pressure is created, causing the blockage to move upwards and approach the conveyor plate 103. There, the blockage is cut by the blades of the conveyor plate 103 and collected by an external barrier net, thus clearing the sewer and facilitating subsequent drainage. When the water flow is controlled to move in the same direction as the drainage, it actively drives the water flow downwards, increasing the impact of the water flow on the blockage to achieve the clearing effect. Furthermore, when the external drainage demand is high, the water flow can be accelerated to improve drainage efficiency.

[0028] like Figure 1 and Figure 4 As shown, the conveyor plate 103 has a spiral plate structure and is provided with an arc.

[0029] Specifically, the conveyor plate 103 is shaped like a fan blade, and its edges are treated to form a blade structure for cutting debris. The spiral structure can be used to control the water flow, such as the conveying direction and conveying speed.

[0030] like Figures 3 to 5As shown, the support rod 106 includes multiple secondary rods 1064. Each secondary rod 1064 consists of a slide rod 1061, an inner connector 1062, and an outer connector 1063. The secondary rods 1064 are slidably mounted on the support plate 105. The slide rod 1061 slides on the support plate 105. The inner connector 1062 and the outer connector 1063 are located at the ends of the slide rod 1061, respectively. The inner connector 1062 is provided with an external thread groove, and the outer connector 1063 is provided with an internal thread.

[0031] Specifically, each end of the support plate 105 is provided with three auxiliary rods 1064, with the middle one being the main one and the two on the sides being auxiliary ones, used to extend the middle auxiliary rod 1064 to adapt to different specifications of sewer inner diameter. During connection, the inner connector 1062 is threadedly connected to the outer connector 1063 on another slide rod 1061.

[0032] like Figure 3 As shown, a contact head 112 is installed on the inner connector 1063, and the contact head 112 is made of flexible material.

[0033] Specifically, the contact head 112 is preferably made of rubber to protect the outer connector 1063 from contact with the inner wall of the sewer, preventing hard contact between the outer connector 1063 and the inner wall and damage to the outer connector 1063. Furthermore, the friction between the hard material of the outer connector 1063 and the inner wall is low, and the rubber material of the contact head 112 can increase the contact area with the inner wall of the sewer through elastic deformation, thereby increasing the friction and ensuring the stability of the installation of the device in this application.

[0034] When extending the secondary rod 1064, remove the contact head 112 on the middle 1602. After extension, install the contact head 112 on the new outermost inner connector 1062.

[0035] like Figure 4 As shown, the telescopic rod 107 includes an inner telescopic rod 1071, an outer telescopic rod 1072, and a spring 1073. The end of the inner telescopic rod 1071 near the moving ring 108 is rotatably connected to the moving ring 108. The spring 1073 is sleeved on the inner telescopic rod 1071, and the outer telescopic rod 1072 is sleeved on the spring 1073. The two ends of the spring 1073 are fixedly connected to the end of the inner telescopic rod 1071 away from the moving ring 108 and the end of the outer telescopic rod 1072 away from the support rod 106, respectively. The end of the outer telescopic rod 1072 near the support rod 106 is rotatably connected to a connecting block on the support rod 106. Specifically, the end of the outer telescopic rod 1072 near the inner telescopic rod 1071 is slidably connected to the inner telescopic rod 1071.

[0036] Specifically, when the moving ring 108 moves downward on the support cylinder 101, it pushes the upper end of the inner telescopic rod 1071. The lower end of the inner telescopic rod 1071 slides on the inner wall of the outer telescopic rod 1072 and pulls the lower end of the spring 1073. Since the upper end of the spring 1073 is fixedly connected to the upper end of the outer telescopic rod 1072, the spring 1073 is stretched. The elastic force generated by the stretching of the spring 1073 pushes the lower end of the outer telescopic rod 1072 outward, that is, away from the support cylinder 101. Thus, the lower end of the outer telescopic rod 1072 pushes the middle auxiliary rod 1064 outward through the connecting block on the support rod 106, so that the contact head 112 on it approaches and closely contacts the inner wall of the sewer. Finally, the elastic force of the spring 1073 maintains the contact effect between the contact head 112 and the inner wall, achieving a stable fixing effect.

[0037] like Figure 2 As shown, the movable ring 108 is provided with a plurality of threaded plates 109, the threaded plates 109 are provided with external threaded grooves, the limiting ring 110 is provided with internal threads, the limiting ring 110 and the threaded plates 109 are threadedly engaged, the threaded plates 109 have a certain elasticity, and the installation radius of the threaded plates 109 is greater than the inner diameter of the limiting ring 110.

[0038] Specifically, a rotating ring 111 is fixedly installed on the limiting ring 110. The end of the limiting ring 110 near the threaded plate 109 is chamfered. The outer diameter of the limiting ring 110 is larger than the outer end face diameter of the threaded plate 109. Thus, when the limiting ring 110 contacts the threaded plate 109, the chamfer can push the upper end of the threaded plate 109 to tilt towards the axis of the support cylinder 101, thereby making the limiting ring 110 and the threaded plate 109 threadedly connected. Then, the limiting ring 110 can be rotated directly, so that the limiting ring 110 gradually moves downward on the threaded plate 109, increasing the tilt of the threaded plate 109, increasing the contact area between the threaded plate 109 and the support cylinder 101, thereby increasing the friction, fixing the position of the moving ring 108 on the support cylinder 101, and finally achieving the contact effect between the contact head 112 and the inner wall of the sewer, stabilizing the position of the device of this application.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
