Description

Technical Field

[0003] Among them, effective drainage and unblocked drainage pipes are an important maintenance means for roads. The drainage manhole covers on existing roads are often directly connected to the drainage pipes to achieve the drainage effect. However, when encountering heavy rain, the water flow in the drainage manhole cover is large, and the water flow will rapidly submerge the connection between the drainage manhole cover and the drainage pipe, affecting the drainage speed; and the fallen leaves, plastic bags, etc. carried in the rainwater are easy to block the drain outlet of the drainage manhole cover, which will also affect the discharge of rainwater. If the drainage pipes and drainage manhole covers are manually unblocked, it will require a lot of manpower and material resources.

[0004] In addition, during heavy rain, a large amount of water will accumulate on the manhole cover, and as the rainwater continues to pass through the manhole cover and enter the drainage pipe below, a small vortex will be formed. The manhole cover covered by rainwater is not easily discovered by pedestrians.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] For example, see Figures 1 to 10 , the present invention provides a technical solution: a drainage method for highway maintenance is as follows:

[0044] The water storage tank 1 is placed at the drainage outlet reserved by the highway. When encountering heavy rain weather, the staff remotely turns on the driving motor 36, and under the action of the pulley transmission mechanism 37, the two threaded rods 13 are driven to rotate, so that the moving block 11 drives the push plate 9 to move back and forth, and the rainwater collected above the leakage groove 39 can be pushed to the two side walls of the water storage tank 1, so that the rainwater accumulated in the water storage tank 1 can be drained, thereby increasing the drainage speed of the drainage pipe 3 in heavy rain weather;

[0045] When the driving motor 36 is turned on and the moving block 11 is driven to move back and forth, the moving rod 18 will drive the multiple cleaning rods 7 to move back and forth in the vertical direction under the action of the hinged plate 19, so that the fallen leaves, plastic bags and other garbage in the leaking port 2 can be pushed out, ensuring the circulation of rainwater in the leaking port 2. When the moving rod 18 moves back and forth in the vertical direction, under the transmission action of the rack row 14 and the gear 16, the rotating rod 15 will rotate back and forth, so that the knocking block 34 on the swinging rod 32 can knock the bell 23 back and forth. With the sound of the two bells 23, the drainage area of ​​the manhole cover 4 flooded by heavy rain can be warned.

[0046] The surface of the water tank 1 is provided with a shell 1 5 and a shell 2 6. The water tank 1, the shell 1 5 and the shell 2 6 are all buried underground. The manhole cover 4 is detachably connected to the top of the water tank 1, and a plurality of water leakage holes 2 are evenly opened on the surface of the manhole cover 4.

[0047] A water leakage groove 39 is provided on the inner wall of the water storage tank 1, a drainage pipe 3 is fixedly connected to the lower surface of the water storage tank 1, two push plates 9 are provided above the water leakage groove 39, a drainage component is provided in the shell 2 6, a cleaning component is provided in the water storage tank 1, and a warning component is provided on the side.

[0048] More specifically, when this embodiment is used, Figure 1 and Figure 2 As shown, the water tank 1, shell 1 5 and shell 2 6 are all buried underground, and only the manhole cover 4 is flush with the upper surface of the ground. When it rains, rainwater on the road surface will fall into the water tank 1 through the multiple leaking holes 2 on the surface of the manhole cover 4, and the rainwater in the water tank 1 will be discharged into the drain pipe 3 through the leaking groove 39 to complete the normal drainage of the highway.

[0049] When encountering heavy rain, a large amount of rainwater will accumulate in the water storage tank 1, and the water flow at this time will gather rapidly and submerge the leakage groove 39. At this time, the drainage component is opened, and under the action of the drainage component, the two push plates 9 above the leakage groove 39 can be moved away from each other and reset.

[0050] In this process, the rainwater collected above the leakage trough 39 can be pushed to both sides of the water storage tank 1 by moving the two push plates 9, thereby avoiding the problem of rainwater congestion above the leakage trough 39 and affecting rainwater discharge.

[0051] It is worth noting that when the two push plates 9 move toward the direction close to the leakage groove 39 for resetting, the two push plates 9 will tilt toward the horizontal direction, that is, in the process of resetting the two push plates 9 toward the direction close to the leakage groove 39, the water flow will not be pushed to the top of the leakage groove 39 again, which has a strong effect on draining rainwater.

[0052] When the drainage component starts to work, the cleaning component will start to work synchronously. Under the action of the cleaning component, the garbage such as fallen leaves, plastic bags, etc. accumulated in the multiple leakage outlets 2 can be cleaned mechanizedly to avoid the problem that the leakage outlets 2 are blocked and affect the drainage effect of the manhole cover 4. The unblocking operation of the manhole cover 4 can be completed without manually unblocking the leakage outlets 2 in heavy rain, saving manpower and material resources.

[0053] And when the drainage component starts to work, the warning component will also start to work. Under the action of the warning component, the drainage point of the manhole cover 4 can be warned, thereby avoiding the problem that pedestrians accidentally walk on the manhole cover 4 and may be knocked down by the rapid rain water in the vortex, causing unnecessary personal injury.

[0054] Embodiment 2, based on the above embodiment,

[0055] Further, the drainage component in the first embodiment is disclosed, and the drainage component includes a driving motor 36 arranged on the side of the water storage tank 1, the output shaft of the driving motor 36 is fixedly connected to the rotating shaft 38, and the inner wall of the water storage tank 1 is fixedly connected to two symmetrically arranged inclined plates 10;

[0056] The surface of the water storage tank 1 is also connected to two symmetrically arranged threaded rods 13 for rotation with a fixed axis, a pulley transmission mechanism 37 is provided between the two threaded rods 13 and the rotating shaft 38, two sections of reciprocating thread grooves are provided on the surface of the threaded rod 13, and two symmetrically arranged moving blocks 11 are threadedly connected to the surface of the threaded rod 13;

[0057] The lower surface of the moving block 11 is fixedly connected to the limiting block, and the inner wall of the water storage tank 1 is provided with a limiting groove 12 for the limiting block to slide and adapt.

[0058] The drainage component also includes a disc 20 fixedly connected to the surface of the moving block 11. The surface of the disc 20 is provided with an arc-shaped slide groove 22. The inner wall of the arc-shaped slide groove 22 is slidably connected with a connecting column 21. The push plate 9 is fixedly connected to the connecting column 21.

[0059] More specifically, when this embodiment is in use, when encountering heavy rain, the staff can remotely turn on the drive motor 36, and the start of the drive motor 36 will drive the rotating shaft 38 to start rotating, and under the action of the pulley transmission mechanism 37, the two threaded rods 13 will rotate synchronously.

[0060] like Figure 3 and Figure 4 As shown, the rotation of the threaded rod 13 will drive the moving block 11 to reciprocate on the reciprocating thread groove, so that the two push plates 9 will first move away from each other and then reset.

[0061] like Figure 3As shown in FIG. 1 , during this process, the push plate 9 on the left side will first move to the left and push the rainwater to move to the left side. At this time, the push plate 9 will be subjected to the reaction force of the rainwater, even the force that causes it to flip to the right side, such as Figure 6 As shown, since the initial state of the connecting column 21 is already at the rightmost side of the arc-shaped slide groove 22, that is, when the push plate 9 moves to the left, it will not cause the push plate 9 to flip to the right. At this time, under the action of the two push plates 9, the rainwater gathered above the leakage groove 39 can be pushed to both sides of the water tank 1.

[0062] When the two push plates 9 move toward each other to reset, as shown in Figure 3 As shown, when the push plate 9 on the left side moves from the leftmost side to the right, the push plate 9 will also be subjected to the reaction force of the rainwater and flipped to the left. At this time, the connecting column 21 will slide in the arc-shaped slide groove 22 until the connecting column 21 moves to the leftmost side of the arc-shaped slide groove 22. At this time, the push plate 9 will also be flipped from the vertical state to the horizontal state, that is, when the two push plates 9 move toward each other to reset, they will not push the rainwater on both sides of the water tank 1 to the middle position of the leakage groove 39.

[0063] In summary, through the reciprocating movement of the two push plates 9, the rainwater accumulated above the leakage trough 39 can be continuously pushed to the two side walls of the water tank 1, thereby avoiding the problem of rainwater congestion above the leakage trough 39 and affecting the discharge of rainwater. In heavy rain weather, the rainwater accumulated in the water tank 1 can be drained, which increases the drainage speed of the drainage pipe 3 in heavy rain weather and provides convenience for subsequent highway maintenance.

[0064] Embodiment 3, based on the above embodiment,

[0065] Further, the cleaning component in the first embodiment is disclosed, and the cleaning component includes a rectangular notch 17 opened on the inner wall of the water storage tank 1, and the inner wall of the rectangular notch 17 is slidably connected with a moving rod 18, and also includes a hinge plate 19, and the side of the moving rod 18 is hinged to the upper surface of the moving block 11 through the hinge plate 19;

[0066] There are two groups of rectangular slots 17 , two of which form a group. A cleaning frame 8 is fixedly connected between the two groups of moving rods 18 . A plurality of cleaning rods 7 are fixedly connected to the upper surface of the cleaning frame 8 . The plurality of cleaning rods 7 correspond to the plurality of water leaks 2 .

[0067] More specifically, when this embodiment is used, Figure 3 and Figure 4As shown, when the driving motor 36 is turned on and drives the moving block 11 to move back and forth, the moving rod 18 is limited by the rectangular slot 17 and can only move in the vertical direction. Under the action of the hinge plate 19, the reciprocating movement of the moving block 11 will drive the moving rod 18 to move back and forth in the vertical direction, thereby causing the multiple cleaning rods 7 on the cleaning frame 8 to move back and forth in the vertical direction.

[0068] The highest point reached by the cleaning rod 7 during the reciprocating movement will not extend above the water leakage port 2. When the cleaning rod 7 moves upward, it will extend into the interior of the water leakage port 2, thereby pushing out garbage such as fallen leaves and plastic bags in the water leakage port 2, ensuring the circulation of rainwater in multiple water leakage ports 2 on the surface of the manhole cover 4. The dredging operation of the manhole cover 4 can be completed without manually dredging the water leakage port 2 in heavy rain, which is highly practical.

[0069] Embodiment 4, based on the above embodiment,

[0070] Further, the warning component in the first embodiment is disclosed, and the warning component includes a rotating rod 15 which is rotatably connected to the inner wall of the water storage tank 1 with a fixed axis, a gear 16 is fixedly connected to the surface of the rotating rod 15, and a rack 14 which meshes with the gear 16 is fixedly connected to the surface of the moving rod 18;

[0071] One end of the rotating rod 15 extending out of the water tank 1 is fixedly connected to a rotating plate 27, and a hinged plate 24 is hinged on the surface of the rotating plate 27. The surface of the water tank 1 is fixedly connected to a limiting plate 26. Two groups of limiting plates 26 are arranged in a group. A moving block 25 is slidably connected between each group of limiting plates 26, and the end of the hinged plate 24 is hinged to the moving block 25.

[0072] The warning component also includes a bell 23 arranged on the side of the water tank 1, a rectangular through hole 30 is opened on the surface of the movable block 25, and two symmetrically arranged support plates 31 are fixedly connected to the surface of the water tank 1. A hinged rod 33 is commonly arranged between the two support plates 31, and a swing rod 32 is hinged on the surface of the hinged rod 33. One end of the swing rod 32 extends into the rectangular through hole 30, and the other end of the swing rod 32 is fixedly connected to a knocking block 34.

[0073] More specifically, when this embodiment is used, Figure 3 As shown, when the moving rod 18 reciprocates in the vertical direction, it also drives the rack row 14 to reciprocate synchronously, thereby causing the gear 16 to reciprocate, so that the rotating rod 15 can reciprocate.

[0074] like Figure 7 to Figure 9As shown, the reciprocating rotation of the rotating rod 15 will drive the rotating plate 27 to rotate reciprocatingly. Since the moving block 25 hinged at the end of the hinged plate 24 is limited by the limiting plate 26, under the hinged action of the hinged plate 24, the reciprocating rotation of the rotating plate 27 will drive the moving block 25 to reciprocate in the horizontal direction within the two limiting plates 26.

[0075] like Figure 8 As shown, during this process, since one end of the swing rod 32 extends into the rectangular through hole 30 on the surface of the moving block 25, and the surface of the swing rod 32 is hinged to the two support plates 31 through the hinge rod 33, the reciprocating movement of the moving block 25 will cause the swing rod 32 to swing back and forth in a circle with the axis of the hinge rod 33 as the axis, and then the knocking block 34 at the other end will reciprocate and knock the bell 23.

[0076] That is, at this time, the two bells 23 arranged on the outer surface of the water storage tank 1 will be repeatedly rung to warn the drainage area of ​​the manhole cover 4 flooded by heavy rain, thereby preventing pedestrians from accidentally walking on the manhole cover 4 and being knocked down by the rapid rain in the vortex, causing unnecessary personal injury.

[0077] Embodiment 5, based on the above embodiment,

[0078] Furthermore, in order to prevent some small-sized garbage and impurities from adhering to the inner wall of the water storage tank 1 and affecting the rotation of the threaded rod 13 and the gear 16 and the movement of the moving rod 18 and the moving block 11, each set of limit plates 26 is slidably connected with a moving block 3 28, and the surface of the rotating plate 27 is hinged with a hinge plate 3 35, and the end of the hinge plate 3 35 is hinged with the moving block 3 28;

[0079] Conductive blocks 29 are provided on the surface of the water storage tank 1 .

[0080] Similarly, with the rotation of the rotating plate 27, under the action of the hinged plate three 35, the movable block three 28 will also reciprocate between the two limit plates 26. The reciprocating movement of the movable block three 28 will reciprocately hit the conductive block 29 and cause the conductive block 29 to vibrate. When the vibration is transmitted to the inner wall of the water tank 1, the garbage and impurities attached to the inner wall of the water tank 1 can be shaken off, and the shaken garbage will be discharged through the drain pipe 3 together with the rainwater.

[0081] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
