Description

Technical Field

[0001] The invention belongs to the field of urban drainage facilities, and in particular relates to a self-controlled sludge sedimentation and drainage inspection well. Background Art

[0002] In the usual drainage system, it is often necessary to set up a sludge well to clean the large amount of sediment generated during the drainage process to prevent pipe blockage; in order to ensure the cleanliness of the water quality of the sponge city rainwater drainage, water storage and water diversion compatible system and prevent the normal operation of the system from being affected by the failure to discharge sediment in time, we set up a sludge tank at the bottom of the overflow well at the lower end of each water storage pipe to precipitate the sediment, which is used to clean the water storage and maintain the system. As the sediment accumulates more and more in the sludge tank, it needs to be cleaned up in time when it reaches a certain level. However, it is generally time-consuming and labor-intensive to remove it manually and mechanically, and a large amount of water in the water storage system must be discharged, resulting in a waste of water. Summary of the invention

When the two ends of the lever are level, the inner slider blocks the water guide port, and when the inner slider rises relative to the hollow rod, the water guide port is opened; the barrel frame is arranged at the lower part of the mud settling tank, and a bucket is arranged in the barrel frame, and a lifting rope is connected to the port of the bucket, and the lifting rope passes upward through the sealing plate and the hollow rod and is connected to the lower end of the inner slider, and a water drainage device is arranged between the bucket and the barrel frame, and when the bucket rises relative to the barrel frame, the water drainage device is closed, and when the bucket descends to the bottom of the barrel frame, the water drainage device is opened.

[0006] The self-controlled sedimentation and sludge discharge inspection well of the present invention may also have the following additional features.

[0007] Preferably, the drainage device includes a drainage hole and an inner valve cover, the drainage hole is arranged at the bottom of the bucket, the inner valve cover is located at the bottom of the inner side of the bucket frame to block the drainage hole, and the inner valve cover is connected to the bottom of the bucket frame through a vertical rod passing through the drainage hole.

[0008] Preferably, an elastic inner limit assembly is further provided on the side wall between the upper end of the hollow rod and the water guide port.

[0009] Preferably, the internal elastic limit assembly includes a limit opening and a sealing cover, a plurality of the limit openings are symmetrically arranged on the side wall of the hollow rod, the inner side of the limit opening leads to the inner side of the hollow rod, the sealing cover is screwed on the limit opening, each sealing cover is connected to a compression spring, the other end of the compression spring is connected to a top ball, a part of the top ball extends into the inner wall of the hollow rod.

[0010] Preferably, a capping slider is further provided in the hollow rod, and the capping slider is connected to the suspension rope above the inner slider.

[0011] Preferably, an inner retaining ring is provided at the upper end of the hollow rod.

[0012] Preferably, a plurality of cutting wires are fixed at the upper end of the sludge shrinkage opening.

[0013] Preferably, a mud discharge port is further provided in the mud settling tank, and the mud discharge port is located below the mud settling port and above the barrel frame. A block removal impeller is also fixed on the outer wall of the hollow rod, and the block removal impeller is located at the upper port of the mud discharge port.

[0014] Preferably, a blocking disk is fixed on the outer side wall of the lower part of the hollow rod, and the blocking disk blocks the mud discharge constriction correspondingly, and the diameter of the blocking disk is larger than the diameter of the bucket mouth of the bucket.

[0015] Preferably, the barrel frame is fixedly connected to the lower end of the mud discharge necking port to stabilize the bucket so that the bucket is relatively stable and cannot swing when moving up and down, and the sealing disk extends into the barrel frame.

[0016] When the weight of the mud tray increases to a certain extent, the mud tray will sink and the outer end of the lever will be pulled down by the lifting rope. When the mud tray moves down to the bottom of the mud shrinkage, the mud will slide down from this mud bin to the mud discharge bin below the mud tray. In order to ensure that the mud can easily slide down the mud tray, the upper surface of the mud tray should be made into a conical surface with a certain slope; in order to prevent the mud agglomerates from being stuck in the mud shrinkage, a cutting wire is fixed above the mud shrinkage, and the fixed cutting wire will cut the mud when the mud tray sinks, and the mud agglomerates are cut longitudinally, so that the mud can slide down the mud tray smoothly; in order to further form the mud into mud, it is convenient for water to discharge the mud from the mud discharge pipe, and the mud needs to be deblocked by the deblocking impeller; because the mud tray moves down, it will move down together with the hollow rod and the blocking cover, at this time The mud shrinkage port is opened, and the mud and water begin to flow down. A strong downward water flow will be formed under the upper water pressure. Under the action of the water flow, the deblocking impeller begins to rotate, and the mud blocks are continuously broken up to achieve the deblocking of the silt blocks. Under the stirring action of the deblocking impeller, mud is formed and enters the mud discharge pipe and is discharged smoothly. Under the action of a large amount of pressurized water, it is discharged from the mud discharge pipe to the nearest sewage inspection well and enters the sewage system. In the process of mud discharge, the inner end of the lever is lifted up, and the inner slider in the hollow rod is pulled up to open the water guide port, and the relatively clean water on the upper part flows into the bucket below through the hollow rod. After a certain delay, the water in the bucket begins to increase continuously. When a certain amount of water is reached, under the action of water gravity, the bucket begins to move down, and the inner slider is pulled down by the rope on the bucket to block the water guide port again. In the process of the slider moving down, the inner end of the lever is pulled down by the rope, so that the outer end of the lever is lifted up, and the mud tray moves up and resets, completing the mud discharge process. At the same time, the bucket falls onto the bucket frame. At this time, the inner valve cover moves up relative to the bucket, the drain hole at the bottom of the bucket opens, and the water in the bucket begins to drain and empty, so as to reduce the weight of the bucket again and prepare for the restoration of the mud state. When restoring this state, as the bucket moves up, the inner cover valve at the bottom of the bucket blocks the drain hole, so as to prepare for the next accumulation of water in the bucket, the weight of the bucket is increased again to provide power conditions for resetting. In order to make the mud tray increase to a certain weight before it starts to move down, an internal elastic limit assembly is provided on the upper part of the hollow rod. The elastic limit assembly can play a certain limiting role on the inner slider, so that the inner slider can be pulled up from the hollow rod by the rope under sufficient tension, so that the water guide port is opened and the mud tray starts to move down. The self-controlled sludge discharge inspection well of the present invention automatically separates and stores sludge and accumulated water through a non-external force mechanism, discharges sludge and accumulated water separately using the lever principle, and uses the accumulated water to flush the sludge, so that the sludge can be easily discharged from the sludge discharge pipe at the bottom of the sludge tank without causing blockage.

DETAILED DESCRIPTION

[0023] refer to Figure 1 and Figure 2 The embodiment of the present invention provides an automatic siltation and mud discharge inspection well, comprising: a siltation pool 1, a hollow rod 5, an inner slider 10 and a barrel frame 7, a horizontal frame 2 is horizontally arranged in the port of the siltation pool 1, a plurality of levers 3 are symmetrically hinged on the horizontal frame 2, the outer end of each lever 3 is radially dispersed, and the inner end of the lever 3 extends to the center position of the siltation pool 1, that is, the upper port of the hollow rod 5, a water guide port 501 is arranged on the side wall of the hollow rod 5 near the upper end, a siltation tray 510 is fixed on the outer side wall of the upper part of the hollow rod 5, the siltation tray 510 corresponds to the sliding sealing siltation shrinkage 101, and the siltation tray 510 is connected to the outer end of the lever 3 through a suspension rope 6;

[0024] The inner slider 10 is slidably disposed inside the hollow rod 5. The upper portion of the inner slider 10 is connected to the inner end of the lever 3 via a suspension rope 6. When both ends of the lever 3 are level, the inner slider 10 blocks the water guide port 501. When the inner slider 10 rises relative to the hollow rod 5, the water guide port 501 is opened.

[0025] The bottom of the sedimentation tank 1 is connected to a sludge discharge pipe 4, and the upper part of the sedimentation tank 1 is provided with a sludge constriction 101;

[0026] The barrel frame 7 is arranged at the lower part of the sludge pool 1, and a bucket 8 is arranged in the barrel frame 7. A lifting rope 6 is connected to the port of the bucket 8. The lifting rope 6 passes upward through the hollow rod 5 and is connected to the lower end of the inner slider 10. A water discharge device is arranged between the bucket 8 and the barrel frame 7. When the weight of the sludge tray 510 increases to a certain extent after the sludge is stored and the sludge tray 510 slides down rapidly in the sludge shrinkage 101, the sludge tray 510 pulls the lever 3 through the lifting rope 6, and the other end of the lever 3 pulls the bucket 8 to rise relative to the barrel frame 7 through the lifting rope 6. At this time, the water discharge device is closed, and the water guide port 501 is opened. The clean water of the upper layer of the sludge in the sludge tray 510 enters the hollow rod 5 from the water guide port 510 and finally flows into the bucket 8.

[0027] After the sludge tray 510 slides downward out of the sludge constriction 101, the sludge in the sludge tray 510 leaks out, the mass on the sludge tray 510 is reduced, and at the same time, the bucket 8 drops due to the increase in mass after the water is stored, so that the lever 3 pulls the sludge tray 510 upward into the sludge constriction 101 through the suspension rope 6. When the bucket 8 drops to the bottom of the barrel frame 7, the drainage device opens, and the water stored in the bucket 8 leaks out, flushing the sludge that falls into the bottom of the sludge pool 1, so that it can be easily discharged from the sludge discharge pipe 4.

[0028] The self-controlled sedimentation and mud discharge inspection well of the present invention also has the following additional embodiments.

[0029] According to one embodiment of the present invention, the water drainage device includes a water drainage hole 801 and an inner valve cover 9, wherein the water drainage hole 801 is arranged at the bottom of the bucket 8, and the inner valve cover 9 is located at the bottom of the inner side of the bucket frame 7 to block the water drainage hole 801, and the inner valve cover 9 is connected to the bottom of the bucket frame 7 through the water drainage hole 801 via a vertical rod 701. When the bucket 8 descends relative to the bucket frame 7, that is, descends relative to the inner valve cover 9, the water drainage hole 801 is in an open state after being separated from the inner valve cover 9, and the water stored in the bucket 8 is discharged. When the bucket 8 rises relative to the bucket frame 7, that is, rises relative to the inner valve cover 9, the water drainage hole 801 begins to be blocked by the inner valve cover 9, and water begins to be stored in the bucket 8.

[0030] like Figures 1 to 4 As shown, according to one embodiment of the present invention, an elastic inner limit assembly is further provided on the side wall between the upper end of the hollow rod 5 and the water diversion port 501. The elastic inner limit assembly is used to provide a downward resistance to the upper part of the inner slider 10, so that the inner slider 10 can be pulled upward from the position of the water diversion port 501 by the lever 3 through the suspension rope 6 only when the mud on the mud tray 510 reaches a certain weight, so that the water diversion port 501 is opened.

[0031] like Figure 3 and Figure 4As shown, according to one embodiment of the present invention, the internal elastic limit assembly includes a limit opening 502 and a blocking cover 503, and multiple limit openings 502 are circularly symmetrically arranged on the side wall of the hollow rod 5, the inner side of the limit opening 502 leads to the inner side of the hollow rod 5, and the blocking cover 503 is screwed on the limit opening 502, and each blocking cover 503 is connected to a compression spring, and the other end of the compression spring is connected to a top ball 505, and a part of the top ball 505 extends into the inner wall of the hollow rod 5.

[0032] According to one embodiment of the present invention, a capping slider 11 is further provided in the hollow rod 5, and the capping slider 11 is connected to the suspension rope 6 above the inner slider 10. The capping slider 11 can prevent debris from entering from the upper end of the hollow rod 5, so that the sliding seal between the inner slider 10 and the inner side wall of the hollow rod 5 will not be affected.

[0033] According to one embodiment of the present invention, the upper end of the hollow rod 5 is provided with an inner retaining ring 506. The inner retaining ring 506 can prevent the capping slider 11 and the inner slider 10 from escaping from the upper end of the hollow rod 5.

[0034] like Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, a plurality of cutting wires 12 are fixed at the upper end of the sludge constriction 101. The upper surface of the sludge tray 510 is a conical surface, and the cutting wires 12 are used to cut the sludge on the sludge tray 510 into small pieces, so that the sludge can easily slide off the upper surface of the sludge tray 510.

[0035] According to one embodiment of the present invention, a sludge discharge constriction 102 is further provided in the sludge tank 1, and the sludge discharge constriction 102 is located below the sludge discharge constriction 101 and above the barrel frame 7. A block-eliminating impeller 13 is also fixed on the outer wall of the hollow rod 5, and the block-eliminating impeller 13 is located at the upper end of the sludge discharge constriction 102. After the sludge slides down from the sludge tray 510, it gathers at the sludge discharge constriction 102. When passing through the sludge discharge constriction 102, the block-eliminating impeller 13 can be driven to rotate under the action of the downstream water flow, and the sludge blocks can be broken into mud. At the same time, the block-eliminating impeller 13 can drive the hollow rod 5 to rotate when rotating, and the sludge tray 510 will also rotate synchronously with the hollow rod 5, so that the sludge that has not fallen off the sludge tray 510 will be thrown out, which plays a role in further cleaning the tray. The stationary cutting wire 12 moves relative to the sludge on the sludge tray 510 to cut the sludge into smaller parts, making it easier to slide off the sludge tray 510.

[0036] like Figure 1 and Figure 2As shown, according to one embodiment of the present invention, a blocking plate 14 is fixed on the outer side wall of the lower part of the hollow rod 5, and the blocking plate 14 corresponds to the blocking mud constriction 102, and the diameter of the blocking plate 14 is larger than the diameter of the barrel mouth of the bucket 8. The outer diameter of the blocking plate 14 is larger than the inner diameter of the mud constriction 102, so that the blocking plate 14 limits the rising height of the hollow rod 5. The barrel frame 7 is fixedly connected to the lower end of the mud constriction 102, and the blocking plate 14 extends into the barrel frame 7. At the same time, the blocking plate 14 can be placed on the upper port of the bucket 8 in the barrel frame 7, which limits the descending height of the hollow rod 5, and the blocking plate 14 can also prevent debris such as sediment from falling into the bucket 8.

[0037] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
