Description

Technical Field

[0001] The present invention relates to the field of municipal drainage engineering, and more particularly to a rainwater inlet with intelligent functions of draining accumulated water and intercepting sewage. Background Art

[0002] Due to the unreasonable design of urban drainage and the frequent occurrence of floods in recent years, the road surface water caused by short-term heavy rainfall is too deep, affecting people's travel and the safety of life and property.

[0003] When designing and verifying the discharge capacity of stormwater inlets, it is crucial to calculate the degree of water accumulation in the flooded area or the efficiency of rainwater drainage from the road surface. Insufficient stormwater discharge capacity can lead to localized waterlogging, even if the rainfall does not reach the design standards for underground stormwater pipes. Therefore, improving the discharge capacity of stormwater inlets during urban flooding is of great significance to the study of urban flood formation mechanisms and flood control and drainage countermeasures.

[0004] Traditional rainwater inlets have the following problems: ① The problem of the discharge capacity of rainwater inlets: the increase in impervious area, that is, due to the increase in the hardened area of ​​the road surface, the water seepage capacity of the ground is greatly weakened, and the flow at the rainwater inlet increases rapidly. It is difficult for traditional rainwater inlets to meet the discharge requirements during continuous rainfall periods. This is also one of the main causes of urban waterlogging; ② The blockage problem: Due to the large gaps in the rainwater grates of traditional rainwater inlets, when it rains, rainwater will wash large particles of debris on the ground into the rainwater inlets. Since there are no effective interception measures, the rainwater inlets are easily blocked, which affects the discharge capacity of the rainwater inlets.

[0005] Therefore, how to provide a rainwater outlet with intelligent drainage and sewage interception functions so as to overcome the above problems is an issue that needs to be urgently addressed by those skilled in the art. Summary of the Invention

[0006] In view of this, the present invention provides a rainwater inlet with intelligent functions of draining accumulated water and intercepting sewage.

[0025] Example

[0026] See attached Figure 1-3 The present invention is a schematic diagram of the overall and partial structures of an embodiment of the present invention. The present invention specifically discloses a rainwater inlet with intelligent drainage and sewage interception functions, including a well body 2, a water inlet grate 1 and a branch pipe. The well body 2 is arranged vertically and a water inlet grate 1 with a rectangular outer contour is buckled at its upper end opening. The branch pipes are respectively connected to the well body 2 and the external drainage pipe. The invention also includes:

[0027] The sewage interception mechanism includes a sewage interception screw 3, a connecting rod 4, a nut 5, a garbage net bag 6 and a driving machine 1;

[0028] Two sewage intercepting screws 3 are supported for horizontal rotation in the well body 2. The rotation direction and thread rotation direction of the two sewage intercepting screws 3 are opposite. The rod length direction of the sewage intercepting screw 3 is parallel to the width direction of the water inlet grate 1, and the rod length direction of the connecting rod 4 is parallel to the length direction of the water inlet grate 1.

[0029] A nut 5 is fixed to each end of the connecting rod 4, and the two nuts 5 are respectively screwed to the sewage intercepting screw 3. When the two sewage intercepting screws 3 rotate synchronously in opposite directions, the connecting rod 4 moves along the width direction of the water inlet grate 1, and the center line of the connecting rod 4 is always perpendicular to the center line of the sewage intercepting screw 3 during the movement.

[0030] The surface of the garbage net bag 6 has mesh holes, and the top of the garbage net bag 6 has a flexible rectangular bag opening. The two opposite sides of the rectangular bag opening are respectively fixed to the connecting rod 4 and the well body 2. The rectangular bag opening is limited between the two sewage intercepting screws 3. When the two sewage intercepting screws 3 rotate synchronously, the opening degree of the rectangular bag opening becomes smaller or larger, thereby realizing the opening and blocking of the rectangular bag opening; the rectangular bag opening can be directly opposite to the upper and lower positions of the water inlet grate 1, and the area of ​​the rectangular bag opening is greater than or equal to the plate surface area of ​​the water inlet grate 1. When the water inlet grate 1 moves upward, the garbage net bag 6 can effectively intercept large pieces of garbage mixed in rainwater and sewage;

A removable rectangular cover plate 23 is provided on the top of the equipment trough to prevent rainwater and sewage on the road surface 21 from seeping into the equipment trough. The rotational connection between the sewage interception screw 3 and the well body 2 is waterproofed to prevent rainwater and sewage from flowing into the equipment trough from the rotational connection. A driving motor is arranged in the equipment trough and is simultaneously connected to the two sewage interception screws 3.

[0032] The driving machine includes a dual-output shaft servo reduction motor 7, a driving bevel gear 8 and a driven bevel gear 9. The dual-output shaft servo reduction motor 7 is fixed on the side wall of the equipment slot. A driving bevel gear 8 is coaxially fixed to each of the two output shafts of the dual-output shaft servo reduction motor 7. One end of the two sewage intercepting screws 3 is coaxially fixed with a driven bevel gear 9 after passing through the side wall of the equipment slot. The two driving bevel gears 8 are engaged with the two driven bevel gears 9 respectively. The opening and closing of the rectangular bag opening of the garbage net bag 6 and the distance moved by the corresponding connecting rod 4 along the length direction of the sewage intercepting screw 3 are achieved by the number of rotations of the dual-output shaft servo reduction motor 7.

[0033] The lifting mechanism includes a lifting screw 10, a nut 11, a connecting rod 12 and a driving machine 2. The horizontal rotating support in the well body 2 has two lifting screws 10 with opposite directions. The two lifting screws 10 are parallel to each other and the ends are aligned. The rod length direction of the lifting screw 10 is parallel to the width direction of the water inlet grate 1. The two lifting screws 10 are respectively arranged directly above the two sewage intercepting screws 3. The lifting screw 10 has two threaded sections with opposite rotation directions. A nut 11 is screwed on each threaded section. When the nut 11 cannot rotate, the lifting screw 10 is rotated, and the movement directions of the two nuts 11 are opposite; the cross-section of the connecting rod 12 is rectangular and there are four of them. One end of the four connecting rods 12 is respectively hinged to the four nuts 11 and the hinge center lines are all horizontally arranged. , the other ends of the four connecting rods 12 are hinged to the lower plate surface of the water inlet grate 1 and the hinge center lines are arranged horizontally, the hinge center lines of the connecting rod 12 and the nut 2 11 and the hinge center lines of the connecting rod 12 and the water inlet grate 1 are perpendicular to the rod axis line of the lifting screw 10, and the driving machine 2 is installed in the equipment slot, and the driving machine 2 is simultaneously connected to the two lifting screws 10 in transmission; the two connecting rods 12 hinged to the two nuts 2 11 rotated on the same lifting screw 10 are arranged in an eight-shaped shape; a threaded section on one lifting screw 10 and a threaded section on the other lifting screw 10 opposite to its left and right positions rotate in opposite directions, that is, when the two lifting screws 10 rotate synchronously in opposite directions, the water inlet grate 1 can be lifted vertically, and the plate surface of the water inlet grate 1 is always arranged horizontally during the lifting process;

[0034] The second drive mechanism includes a dual-output servo reducer motor (13), a driving bevel gear (14), and a driven bevel gear (15). The dual-output servo reducer motor (13) is fixed to the sidewall of the equipment slot. A driving bevel gear (14) is coaxially fixed to each of the two output shafts of the dual-output servo reducer motor (13). After passing through the sidewall of the equipment slot, one end of each of the two lifting screws (10) is coaxially fixed to a driven bevel gear (15). The two driving bevel gears (14) mesh with the two driven bevel gears (15). The lifting height of the water inlet grate (1) is determined by the number of revolutions of the dual-output servo reducer motor (13).

[0035] Control component, which includes a Doppler flow meter 16, a controller 17, a photovoltaic power generation device and an obstacle detection sensor 20;

[0036] The Doppler flowmeter 16 and the controller 17 are both installed in the equipment slot. The detection probe 160 of the Doppler flowmeter 16 is fixed to the inner wall of the well body 2. The detection probe 160 is limited between the sewage interception screw 3 and the lifting screw 10. The detection end of the detection probe 160 points to the water inlet grate 1. The Doppler flowmeter 16 can perform non-contact flow velocity measurement of the rainwater and sewage flowing from the water inlet grate 1 into the well body 2, and use this to judge the water accumulation situation of the road surface 21. The deeper the water accumulation on the road surface 21, the faster the flow rate of the rainwater and sewage flowing from the water inlet grate 1 into the well body 2.

[0037] The photovoltaic power generation device includes a vertical pole 18 and a solar panel 19. The vertical pole 18 with a circular cross-section is vertically arranged on one side of the water inlet grate 1 and a solar panel 19 is installed on its upper end. In this embodiment, a shoulder 22 is arranged between the vertical pole 18 and the water inlet grate 1, and the vertical pole 18 is fixed on the auxiliary road or the flower bed; the obstacle detection sensor 20 is fixed on the vertical pole 18 and its transmitting end points to the periphery of the water inlet grate 1, that is, the obstacle detection sensor 20 can detect the front side, the rear side and the side away from the shoulder 22 of the water inlet grate 1. When a vehicle or pedestrian passes near the water inlet grate 1, the obstacle detection sensor 20 is triggered and sends a signal to the controller 17, and the obstacle detection sensor 20 is relatively The installation height on the road surface 21 cannot be lower than 0.3 meters and cannot be higher than 1.8 meters. The purpose of this setting is to ensure that the obstacle detection sensor 20 can detect reliably; the dual-output shaft servo reduction motor 17, the dual-output shaft servo reduction motor 2 13, the Doppler flow meter 16, the obstacle detection sensor 20 and the solar panel 19 are all electrically connected to the controller 17. The solar panel 19 can store electricity when there is sufficient sunshine and can still provide stable power supply in rainy weather. It mainly supplies power to the dual-output shaft servo reduction motor 17, the dual-output shaft servo reduction motor 2 13, the Doppler flow meter 16, the obstacle detection sensor 20 and the controller 17.

[0038] Under weather conditions without rain or insufficient rainfall, the Doppler flowmeter 16 cannot detect the flow rate of rainwater and sewage flowing from the water inlet grate 1 into the well body 2, or the flow rate of rainwater and sewage flowing from the water inlet grate 1 into the well body 2 is too slow, and the Doppler flowmeter 16 will not be triggered. At this time, the water inlet grate 1 will not rise vertically, and the rectangular bag mouth of the garbage net bag 6 is in a closed state.

[0039] Under conditions of sufficient rainfall, the flow rate of rainwater and sewage flowing from the water inlet grate 1 into the well body 2 reaches the detection threshold of the Doppler flowmeter 16. At this time, the Doppler flowmeter 16 sends a signal to the controller 17, which drives the dual-output shaft servo reduction motor 1 7 and the dual-output shaft servo reduction motor 2 13 to rotate in the forward direction. The water inlet grate 1 rises, the rectangular bag opening of the garbage net bag 6 opens, and the flow rate of rainwater and sewage entering the well body 2 increases rapidly, thereby achieving rapid drainage of accumulated water.

[0040] Two minutes after the water inlet grate 1 is raised, the rectangular bag opening of the garbage net bag 6 is in an open state. The purpose of this setting is to enable the garbage net bag 6 to intercept large pieces of garbage in the initial influx of rainwater and sewage to prevent them from clogging the branch pipe. After two minutes, the controller 17 drives the dual-output shaft servo reduction motor 1 7 to rotate in the reverse direction, and the rectangular bag opening of the garbage net bag 6 returns to a closed state.

[0041] During the period when the water inlet grate 1 is raised, the obstacle detection sensor 20 performs real-time detection on the periphery of the water inlet grate 1. When a person or a vehicle approaches the water inlet grate 1, the obstacle detection sensor 20 is triggered and sends a signal to the controller 17. The controller 17 drives the dual-output shaft servo reduction motor 2 13 to rotate in the reverse direction, and the water inlet grate 1 resumes its buckling on the well body 2. After the obstacle detection sensor 20 detects no obstacles around the water inlet grate 1, the controller 17 drives the dual-output shaft servo reduction motor 2 13 to rotate in the forward direction, and the water inlet grate 1 is raised again.

[0042] When the flow rate of rainwater and sewage flowing from the water inlet grate 1 into the well body 2 is less than the detection threshold of the Doppler flowmeter 16, the controller 17 drives the dual-output shaft servo reduction motor 2 13 to rotate in the opposite direction again, and the water inlet grate 1 resumes its buckling position on the well body 2.

[0043] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
