Description

Technical Field

[0001] The utility model relates to the technical field of drainage manhole covers, in particular to an energy-saving drainage and anti-blocking structure for municipal engineering. Background Art

[0002] Energy-saving drainage wells in municipal engineering are an indispensable part of urban infrastructure. They enable the rapid discharge of rainwater and sewage to prevent urban waterlogging and pollution. The structure of such wells includes well covers, well shafts, well bottoms, drainage pipes, and filtering devices. The well covers bear weight and ensure safety, the well shaft is the main structure, the well bottom collects sewage, the drainage pipes discharge sewage, and the filtering devices are used to improve water quality.

[0003] For example, a rotary anti-blocking manhole cover used in municipal engineering disclosed in the application publication number CN113882434A includes a manhole cover body and a manhole cover embedded bracket, a pillar is welded in the middle of the lower surface of the inner wall of the manhole cover body, and a manhole cover plate is welded at the upper end of the pillar, an anti-blocking mechanism is arranged on the inner wall of the manhole cover body, and a transmission mechanism is installed at the lower end of the manhole cover body, and a drainage hole is opened at the lower end of the manhole cover body, so that people do not need to clean the manhole cover when it rains. The water flow of the drainage pipe drives the rotating plate to rotate to clean up the debris on the manhole cover driven by the water flow, so as to ensure that the accumulated water on the ground can flow into the sewer through the manhole cover. However, this technical solution needs to ensure that the water flow has a certain flow rate and flow rate during use.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 The utility model provides an embodiment: a municipal engineering energy-saving drainage and anti-blocking structure, comprising a wellbore inner tube 1 and a manhole cover body 2 hingedly installed at the top opening position of the wellbore inner tube 1, a double-layer annular outer steel sleeve 3 is fixed to one end of the surface of the wellbore inner tube 1, and two symmetrical T-shaped shaft frames 4 are symmetrically installed on the outer walls of both sides of the double-layer annular outer steel sleeve 3, an active crushing shaft 5 is rotatably installed between the two T-shaped shaft frames 4 in the same X-axis direction, and a driven crushing shaft 6 is rotatably installed between the two T-shaped shaft frames 4 in the other X-axis direction, and a belt transmission structure 7 for maintaining power connection is arranged at the same end of the active crushing shaft 5 and the driven crushing shaft 6, and a partition beam 9 parallel to the active crushing shaft 5 and the driven crushing shaft 6 is arranged at the central position inside the wellbore inner tube 1, and the design of the partition beam 9 can also increase the structural stability of the wellbore inner tube 1, prevent the wellbore from being deformed or damaged due to the accumulation of dirt, and extend the service life of the drainage system;

[0021] A motor controller 11 is installed on the outer wall of one side of one of the T-shaped shaft frames 4, and the output end of the motor controller 11 is electrically connected to the input end of the rotation drive unit 8. Through the motor controller 11 and the control of the staff, the operator can start or stop the crushing function at any time according to the needs of the well, and flexibly control the operating state of the well;

[0022] The outer surfaces of the active crushing shaft 5 and the driven crushing shaft 6 are both equipped with a plurality of cross cutters 10 at equal intervals, and the cross cutters 10 are made of alloy steel.

[0023] The outer surface of the double-layer annular outer steel sleeve 3 is integrally formed with a plurality of equally spaced connecting ribs 301. Since the drainage shaft usually needs to withstand the influence of groundwater pressure and geological conditions, the reinforcement design of the double-layer annular outer steel sleeve 3 can effectively resist external pressure and force, and prevent the shaft inner tube 1 from being deformed or damaged due to the influence of the external environment, thereby extending the service life of the drainage system;

[0024] The rotation driving unit 8 includes a reduction motor installed on the outer wall of one side of the T-shaped shaft frame 4, and a pulley transmission structure installed at the output end of the reduction motor for driving the active crushing shaft 5 to rotate. The pulley transmission structure includes a main synchronous wheel installed on the output end of the reduction motor, and a secondary synchronous wheel installed at one end of the surface of the active crushing shaft 5. A multi-V belt is wound between the secondary synchronous wheel and the main synchronous wheel.

[0025] When the rotary drive unit 8 adopts a reduction motor and a pulley transmission structure, the reduction motor can convert the high-speed rotation power output into a suitable low-speed rotation, so that the crushing shaft has a larger torque and a more stable speed when working;

[0026] A plurality of tooth blade protrusions 901 are integrally formed on the outer walls on both sides of the partition beam 9 close to the active crushing shaft 5 and the driven crushing shaft 6. A recessed portion 902 is provided between two adjacent tooth blade protrusions 901, and the cross cutter 10 is located in the recessed portion 902. After the active crushing shaft 5 and the driven crushing shaft 6 are driven to rotate, the cross cutter 10 will actively crush foreign matter to prevent blockage of the wellbore inner tube 1. Since the cross cutter 10 is located in the recessed portion 902, the tooth blade protrusion 901 is engaged with the cross cutter 10, which further increases the range of action of the crushing shaft in the wellbore.

[0027] When the embodiment of the present application is in use, the shaft inner tube 1 and the manhole cover body 2 are first pre-buried underground and connected to the drainage shaft, and the upper surface of the manhole cover body 2 is flush with the ground. After rainwater and foreign objects carried by rainwater flow into the shaft inner tube 1 through the manhole cover body 2, the water flow will pass through the shaft inner tube 1 and flow into the drainage pipe. The drainage pipe is connected to the bottom of the well, a sewage treatment plant or a river, so as to discharge the collected sewage. In this process, foreign objects in the water flow will be intercepted by the partition beam 9, the active crushing shaft 5, and the driven crushing shaft 6, that is, some of the foreign objects are directly blocked by the partition beam 9, the active crushing shaft 5, and the driven crushing shaft 6. When the shaft is blocked and water accumulates, the staff turns on the rotary drive unit 8 through the motor controller 11 to work, and the return of the rotary drive unit 8 The rotational force is first transmitted to the active crushing shaft 5, and then the driven crushing shaft 6 rotates together with the active crushing shaft 5 under the drive of the belt drive structure 7. At this time, the cross cutting knife 10 actively rotates to achieve the purpose of crushing and throwing away foreign matter. The anti-blocking structure adopts a rotary drive unit 8 for driving. The operation of the two crushing shafts can be achieved through the motor controller 11 and the staff control, so that the operator can start or stop the crushing function at any time according to the needs of the well, and flexibly control the operating state of the well. At the same time, during the sewage discharge process, dirt may accumulate and clog at any position in the well. The double-axis crushing structure can effectively increase its own action area in the well inner tube 1, effectively crush foreign matter, prevent the occurrence of blockage, and ensure the smooth operation of the drainage system.
