Description

Technical Field

[0001] The invention relates to the field of water supply and drainage, in particular to a water supply and drainage flood prevention rapid drainage device. Background Art

[0002] In order to prevent the municipal drainage wells from being blocked by urban garbage during flood season, causing water accumulation on urban roads, the most commonly used method in the prior art is to open the well cover before rainfall, and then set a warning sign above the opened well. Although this method can be applied to any type of drainage well, the drainage speed is controlled by the size of the well opening. If the well is too small, the accumulated water cannot be discharged quickly. If the well is too large, pedestrians or vehicles may fall if they do not pay attention to the warning sign or the warning sign is displaced by rain. For example, a municipal water supply and drainage device with anti-blocking function disclosed in announcement number CN 114293644 A3 has the principle of achieving rapid discharge of accumulated water by changing the opening size, which has the above-mentioned problems.

[0003] The smart flood diversion equipment for urban flood control during heavy rain disclosed in announcement number CN105525669B and the drainage structure for municipal road flood control disclosed in announcement number CN214362657U use sensors to activate the flood control structure for flood control and drainage after the water level rises. However, this solution uses a large number of electrical components, and most municipal drainage wellheads are located in harsh environments such as outdoors or underground. The electrical components are easily affected by moisture or vibration, leading to failure, high cost of use, and poor practicality. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention adopts a water supply and drainage flood prevention rapid drainage device, which solves the problem that the prior art drainage structure is difficult to balance rapid drainage and reduction of falling risks and the problem that the drainage structure is high in cost and prone to failure.

The two water baffles can block the opening when they are in a horizontal position. When the water storage box moves downward to the lower end, the water baffle can open the opening. When the water storage box moves upward to the upper end, the water baffle can rotate to a horizontal state to close the opening.

[0008] The outer edge surface of the inner shell is provided with an annular groove, the second cylinder is placed in the annular groove, and the upper and lower end surfaces of the second cylinder are respectively fitted with the upper and lower end surfaces of the annular groove, an annular plate is arranged in the annular groove, the annular plate is rotatably connected to the inner shell through a bearing, the inner side surface of the annular plate and the annular groove are fixedly connected through a spring, the annular plate is rotatably connected to the second cylinder through a one-way bearing, when the water storage box moves downward, the annular plate can drive the second cylinder to rotate through the one-way bearing, otherwise the second cylinder does not rotate;

[0010] A slider is fixed to the front and rear end surfaces of the water storage box respectively, and a vertical slide groove is opened on the front and rear end surfaces of the vertical pipe respectively. The slider is placed in the slide groove and can slide up and down freely.

[0011] A through hole is respectively provided at the middle of the front and rear end surfaces of the water storage box below the hinge axis of the water baffle plate. A pin shaft that can slide forward and backward is provided in each through hole. In the absence of external force, the end of the pin shaft close to the inner side of the water storage box cavity always extends out of the through hole and can prevent the left and right water baffle plates from swinging downward from the horizontal direction.

[0026] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0027] Depend on Figures 1 to 6The present invention comprises a cylindrical outer shell 1, the upper end surface of the outer shell 1 is a grid plate, a cylindrical inner shell 2 is coaxially fixed inside the outer shell 1, a first cylinder 3 is arranged inside the outer shell 1, a second cylinder 4 is arranged outside the inner shell 2, a plurality of obliquely placed guide plates 5 are fixed between the first cylinder 3 and the second cylinder 4, all the guide plates 5 are evenly distributed around the circumference of the axis of the second cylinder 4 and have the same inclination direction relative to the axis of the second cylinder 4, and a plurality of first drain ports 6 are evenly distributed along the circumference at the lower end surface of the outer shell 1 between the first cylinder 3 and the second cylinder 4;

[0028] A second water outlet 7 communicating with the cavity of the inner shell 2 is provided in the middle of the lower end surface of the outer shell 1. A vertical pipe 8 is fixed to the end of the second water outlet 7. A water storage box 9 that can move up and down is provided inside the vertical pipe 8. When the water storage box 9 moves downward, the second cylinder 4 can rotate around the axis. When the water storage box 9 moves upward, the second cylinder 4 does not rotate.

[0029] The lower end surface of the water storage box 9 is open, and water baffles 10 are hinged on the left and right sides of the lower end opening of the water storage box 9. When the two water baffles 10 are in a horizontal position, they can block the opening. When the water storage box 9 moves downward to the lower end, the water baffle 10 can open the opening. When the water storage box 9 moves upward to the upper end, the water baffle 10 can rotate to a horizontal state to close the opening.

[0030] An annular groove 11 is provided on the outer edge of the inner shell 2, the second cylinder 4 is placed in the annular groove 11, and the upper and lower end surfaces of the second cylinder 4 are respectively fitted with the upper and lower end surfaces of the annular groove 11, and an annular plate 12 is provided in the annular groove 11, the annular plate 12 is rotatably connected to the inner shell 2 through a bearing, the inner side surface of the annular plate 12 and the annular groove 11 are fixedly connected through a spring 13, the annular plate 12 is rotatably connected to the second cylinder 4 through a one-way bearing, and when the water storage box 9 moves downward, the annular plate 12 can drive the second cylinder 4 to rotate through the one-way bearing, otherwise the second cylinder 4 does not rotate;

[0031] A threading hole 14 connected to the annular groove 11 is respectively opened on the left and right sides of the lower end surface of the inner shell body 2, and a steel wire rope 15 is fixed on the left and right sides of the water storage box 9. The other end of the steel wire rope 15 passes through the threading hole 14 and is fixed on the inner edge surface of the annular plate 12.

[0032] A slider 18 is fixed to each of the front and rear end surfaces of the water storage box 9, and a vertical slide groove 19 is provided on each of the front and rear end surfaces of the vertical pipe 8. The slider 18 is placed in the slide groove 19 and can slide freely up and down.

[0033] A through hole 16 is respectively provided at the middle of the front and rear end surfaces of the water storage box 9 below the hinge axis of the water baffle 10. Each through hole 16 has a pin shaft 17 that can slide forward and backward. In the absence of external force, the end of the pin shaft 17 close to the inner side of the cavity of the water storage box 9 always extends out of the through hole 16 and can prevent the left and right water baffles 10 from swinging downward from the horizontal direction. The inner end of the pin shaft 17 is an inclined surface. When the two water baffles 10 swing upward from the lower side of the pin shaft 17, the water baffle 10 can squeeze the pin shaft 17 outward through the inclined surface to give way;

[0034] A pressure block 20 is connected to the bottom of each slider 18 through a spring, and the pressure block 20 is fixedly connected to the outer end of the pin shaft 17 through a pull rope. A first stop block 21 is fixed to the bottom of the slide groove 19 on the front and rear sides of the water storage box 9. When the water storage box 9 moves to the lowermost end, the first stop block 21 can overcome the spring force and squeeze the pressure block 20 upward. The pressure block 20 can pull the pin shaft 17 outward through the pull rope, so that the inner end of the pin shaft 17 extends into the through hole 16.

[0035] Each of the pins 17 is fixedly connected to the through hole 16 via a compression spring, and the compression spring enables the pin 17 to always extend out of the through hole 16 toward the inner side of the water storage box 9.

[0036] One end of each water baffle 10 away from the inner side of the water storage box 9 extends out from the left and right end surfaces of the water storage box 9, and a second stopper 22 is fixed on the left and right sides of the upper end of the vertical pipe 8. When the water storage box 9 moves to the uppermost end, the second stopper 22 can block the outer end of the water baffle 10 and make it swing horizontally.

[0037] The lower sides of the left and right end surfaces of the water storage box 9 are respectively provided with clearance grooves 23. When the inner end of the water baffle plate 10 swings downward, the outer end of the water baffle plate 10 can be placed in the clearance groove 23.

[0038] It is worth mentioning that there is a large gap between the water storage box 9 and the inner wall of the vertical pipe 8, especially the gap between the left and right ends. When the rainfall is too heavy, rainwater can be discharged through the gap between the water storage box 9 and the vertical pipe 9, avoiding the water storage box 9 hindering the normal drainage of the vertical pipe 8 when the rainfall is too heavy.

[0039] When the present invention is used, the outer shell 1 is first pre-buried under the road surface at the location of the municipal drainage outlet, so that the upper end surface of the outer shell 1 is flush with the road surface, and then the first drainage outlet 6 and the second drainage outlet 7 are connected to the municipal drainage pipeline, the clockwork 13 is always in a power storage state and the water storage box 9 is located at the uppermost end, and the steel wire rope 15 is spirally wound between the annular plate 12 and the inner shell 2;

[0040] When it rains, rainwater on the road surface can first flow into the gap between the outer shell 1 and the inner shell 2 through the holes on the grille plate on the upper end surface of the outer shell 1, and then flow downward through the first cylinder 3 and the second cylinder 4 and be discharged into the municipal drainage pipe through the first drain port 6;

[0041] When encountering extremely heavy rainfall, when the drainage volume of the first drain port 6 is less than the rainfall in the rainfall receiving area, the accumulated water can pass over the upper end surface of the inner shell 2 and be discharged downward through the inner side of the inner shell 2, that is, it can be discharged downward through the second drain port 7. The water discharged through the second drain port 7 can fall into the water storage box 9. As the water storage volume in the water storage box 9 increases, the gravity of the water storage box 9 increases to the point where it can overcome the spring torque, and the water storage box as a whole slides downward along the slide groove 19. During the downward sliding process of the water storage box 9, the pull rope can be used to drive the pull rope to pull ... The annular plate 12 rotates, and the annular plate 12 can drive the second cylinder 4 to rotate through the one-way bearing. When the second cylinder 4 rotates, it can accelerate the drainage speed between the first cylinder 3 and the second cylinder 4 through the guide plate 5, so that the accumulated water is quickly discharged downward through the first drain port 6, until the water storage box 9 moves to the point where the pressing block 20 contacts the first stopper 21, and the water storage box 9 continues to move downward, but the pressing plate 20 is blocked by the first stopper 17 and cannot move, that is, relative to the upward movement of the water storage box 9, the pressing plate 20 is pulled by the pull rope to change direction. The movable pin shaft 17 moves outward and disengages from the lower end surface of the water baffle plate 10. The water baffle plate 10 swings downward along the hinge axis under the gravity of itself and the water to open the lower end opening of the water storage box 9. The water in the water storage box 9 is discharged at once, and the gravity of the water storage box 9 is restored to the initial gravity. The force of the torsion spring is reduced and reset. The water storage box 9 is pulled upward and reset by the annular plate 12 and the wire rope 15 until the water storage box 9 moves to the uppermost end. The outer ends of the water baffle plates 10 on the left and right sides are restored to the horizontal position under the blockage of the second stopper 22 to block the water storage again. The lower end of the box 9 is open, and the water baffle 10 can squeeze the pin 17 outward through the inner inclined surface of the pin 17 to make it give way during the process of resetting to the horizontal direction. After the water baffle 10 swings upward to a height exceeding the pin 17, that is, the water baffle swings to the horizontal position, the pin 17 can be reset inwardly under the action of the spring to block the water baffle 10 from swinging downward again, so that the water storage box 9 can re-collect the rainwater discharged from the second inner drain port 7, and repeat the above steps until the accumulated water is reduced to a level that cannot enter the inner side of the inner shell 2.

[0042] The present invention sets two layers of drain outlets, inner and outer, so that when the rainfall is small, drainage is only conducted through the first drain outlet 6 on the outer side. When the rainfall is heavy, drainage can be assisted through the second drain outlet 7 on the inner side. At the same time, the rainwater is collected by the water storage box 9, and the annular plate 12 and the second cylinder 4 drive the guide plate 5 to rotate and accelerate drainage, thereby greatly improving drainage efficiency. The present invention provides a power source through a purely mechanical structure, thereby greatly improving the practicality of the device in a complex environment. The drainage is accelerated by rotating the guide plate 5 to pump water downward, which is safer than increasing the drainage outlet to increase the drainage volume.

[0043] When the water storage box 9 moves downward, the pressure plate 20 cooperates with the first stopper 21 to pull the pin shaft 17 outward to release the water baffle plate 10. When the water storage box 9 moves upward, the interference between the outer end of the water baffle plate 10 and the second stopper 22 is used to make the water baffle plate 10 close the lower end opening of the water storage box 9 again. The gravity of the water in the water storage box 9 and the torsion of the torsion spring offset and release each other, so as to realize the continuous rotation of the annular plate 12. The one-way bearing is used to make the annular plate 12 only drive the guide plate 5 to rotate in one direction, so as to realize continuous pumping.

[0044] The present invention provides a water storage box 9 to collect rainwater and move it downward to discharge after it is filled to a certain amount, so that the rainwater in the vertical pipe 5 is discharged in a pulsed manner. After the water is collected, the gravity of the water is increased, and the kinetic energy provided by the drainage water flow each time is greater, which flushes the vertical pipe 5 and subsequent municipal drainage pipes, effectively preventing the accumulation and residue of dirt in the pipes, and reducing the risk of blockage of municipal sewage pipes.
