Description

[0001] This is a divisional application of a multi-purpose dredging tool for cleaning sediment in inspection wells and its operation method (Patent Application: 2021105802333; Application Date: May 26, 2021). Technical Field

[0002] The present invention belongs to the technical field of drainage pipe network maintenance, and particularly relates to an operation method for cleaning sediment in inspection wells. Background Art

[0003] Sedimentation inevitably occurs in the inspection wells of the drainage pipe network, and it is necessary for operation and maintenance staff to conduct dredging regularly or irregularly. Although the conventional spoon-shaped dredging tool has low efficiency, it is relatively effective for soft sediment. However, in some inspection wells, the sedimentation is relatively dense, and the conventional dredging tool hardly works. At this time, it is necessary for staff to work in the well, but generally the risk is relatively high and the efficiency is low. For inspection wells where it is impossible to block the precipitation, the difficulty and risk of working in the well will be even greater. Therefore, it is necessary to propose a method for cleaning sediment with high density in response to the above problems. Summary of the Invention

[0026] The outer end of the support rod is provided with a notch for a wrench;

[0029] Preferably, the rotating door plate is connected to the cleaning bucket through a rotating shaft, and a torsion spring is provided between the rotating shaft and the rotating door plate.

[0032] The present patent can achieve the following beneficial effects:

[0033] 1. When the present invention is used, the operator stands beside the inspection well, holds the grip rod and vertically inserts the cleaning bucket into the inspection well, and forces the cleaning bucket into the sediment. The sediment will be squeezed to rotate the rotating door plate and enter the cleaning bucket. The operator lifts the cleaning bucket, and the sediment in the cleaning bucket will reset the rotating door plate under the action of gravity. The rotating door plate serves as a supporting surface to support the sediment, thus completing the dredging work. The working mode of the multi-purpose dredging tool is straight up and down, which is very suitable for the vertically narrow working space of the inspection well. It has a good cleaning effect on the inspection well with relatively dense siltation, avoids the operator from working in the well, has high work efficiency and is convenient to operate.

[0034] 2. The technical solution adds a window and a baffle structure, and its purpose is explained in combination with the figure: Most of the sediment will enter the cleaning bucket from the bottom of the cleaning bucket, but it is not easy for the sediment to fill the entire cleaning bucket. After designing the window and the baffle, the sediment around the upper part of the cleaning bucket will squeeze the baffle, causing the baffle to rotate and thus enter the cleaning bucket; in this way, the upper space of the cleaning bucket is also easily filled with sediment; when the cleaning bucket is lifted upward, the baffle will rotate downward under the action of gravity, playing a role in closing the window. Therefore, the amount of sediment cleaned each time can be increased, and the work efficiency can be improved.

[0035] 3. The support rod mechanism is changed to a plug rod mechanism. The strip board is of a flat structure, occupying less space and thus having less resistance. The driving structure is moved to the upper part of the cleaning bucket, that is, the pressing handle, the spring and the arc-shaped protrusion are moved upward. The pressing handle, the spring and the arc-shaped protrusion are not easily in excessive contact with sediment, which helps to reduce the resistance. On the contrary, setting the pressing handle, the spring and the arc-shaped protrusion at the lower part of the cleaning bucket will increase the movement resistance of the cleaning bucket.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0048] The preferred solution is as Figures 1 to 7As shown in the figure, an operation method for cleaning sediment in inspection wells uses a multi-purpose dredging tool for cleaning sediment in inspection wells. The tool includes a grip rod 1, one end of the grip rod 1 is connected to a cleaning bucket 2, the bottom of the cleaning bucket 2 is an open structure, and a rotating door plate 3 is rotatably arranged at the bottom of the cleaning bucket 2; one end of the rotating door plate 3 is hinged to the cleaning bucket 2, and the other end of the rotating door plate 3 is used to rest on a support 4, and the support 4 is connected to the cleaning bucket 2; a window 8 is provided at the upper part of the cleaning bucket 2, and a baffle 9 is rotatably arranged at the window 8.

[0049] As Figure 1 shown in the figure, the operator stands beside the inspection well 7, holds the grip rod 1 and vertically inserts the cleaning bucket 2 into the inspection well 7, and forces the cleaning bucket 2 into the sediment. The sediment will be squeezed and rotate the rotating door plate 3 and enter the cleaning bucket 2. The operator lifts the cleaning bucket 2, and the sediment in the cleaning bucket 2 will reset the rotating door plate 3 under the action of gravity. The rotating door plate 3 serves as a support surface to support the sediment, thus completing the dredging work. The working mode of this multi-purpose dredging tool is straight up and down, which is very suitable for the vertically narrow working space of the inspection well 7, and has a good cleaning effect and convenient operation for inspection wells with relatively dense sediment accumulation.

[0050] The structure of the window 8 and the baffle 9 is added in this technical solution, and its purpose in combination with Figure 7 is explained as: Most of the sediment will enter the cleaning bucket 2 from the bottom of the cleaning bucket 2, but it is not easy for the sediment to fill the entire cleaning bucket 2. After designing the window 8 and the baffle 9, the sediment around the upper part of the cleaning bucket 2 will squeeze the baffle 9 and make the baffle 9 rotate, so as to enter the cleaning bucket 2; in this way, the upper space of the cleaning bucket 2 is also easily filled with sediment; when the cleaning bucket 2 is lifted upward, the baffle 9 will rotate downward under the action of gravity, playing a role in closing the window 8. Therefore, the amount of sediment cleaned each time can be increased, and the work efficiency can be improved.

[0051] In order to improve the operation efficiency of this multi-purpose dredging tool, on the premise of ensuring sufficient mechanical strength, the cleaning bucket 2 is made as thin as possible.

[0052] Furthermore, as Figure 2 shown in the figure, the number of the rotating door plates 3 is two, and the two rotating door plates 3 are respectively hinged to the two side edges of the bottom of the cleaning bucket 2. The movable ends of the two rotating door plates 3 are arranged obliquely upward and rest on the support 4. The two rotating door plates 3 are arranged in an inverted "V" shape, and the angle is preferably between 120° and 150°.

[0053] Without exceeding the design concept, one rotating door plate 3 can also be selected. One end of the rotating door plate 3 is hinged to the inner wall of the cleaning bucket 2, and the support 4 is arranged at the inner wall on the other side of the cleaning bucket 2.

[0054] Furthermore, as Figure 3 and Figure 5As shown in the figure, the supporting member 4 includes a support rod 401. The support rod 401 penetrates through the side wall of the cleaning bucket 2 and is threadedly connected to an internally threaded cylinder 402. The internally threaded cylinder 402 is fixed to the outer wall of the cleaning bucket 2. After the cleaning bucket 2 lifts the sediment, rotate the support rod 401 to move it outwards. The support rod 401 disengages from the rotating door piece 3, and the rotating door piece 3 rotates downwards to discharge the sediment.

[0055] Furthermore, a wrench - mating notch 403 is provided at the outer end of the support rod 401. The wrench - mating notch 403 is used to be adapted to a wrench.

[0056] Furthermore, the number of the supporting members 4 is two, and there is a sediment - passing gap between the two support rods 401 of the two supporting members 4. The support rod 401 slightly protrudes from the inner wall of the cleaning bucket 2. The support rod 401 only needs to support the rotating door piece 3. If the support rod 401 is too long or the support rod 401 crosses through the cleaning bucket 2, it will prevent the sediment from entering the cleaning bucket 2.

[0057] Furthermore, as Figures 3 - 4 shown in the figure, a grip - rod connecting frame 5 is provided at the top of the cleaning bucket 2, and the grip - rod connecting frame 5 is connected to the grip rod 1. The grip rod 1 is composed of a plurality of sub - grip rods 101, and adjacent two sub - grip rods 101 are threadedly connected.

[0058] Furthermore, the rotating door piece 3 is connected to the cleaning bucket 2 through a rotating shaft 6, and a torsion spring is provided between the rotating shaft 6 and the rotating door piece 3.

[0059] The torsion spring helps the two rotating door pieces 3 to close when the cleaning bucket 2 is lifted. The elastic force of the torsion spring should not be too large, otherwise it will affect the sediment entering the cleaning bucket 2.

[0060] The preferred solution is as Figure 4 shown in the figure. The connection method between the supporting member 4 and the grip - rod connecting frame 5 is improved. Specifically: a double - hole ear plate 10 is provided at the top of the grip - rod connecting frame 5, and a U - shaped plate 12 is provided at the bottom of the grip rod 1; the double - hole ear plate 10 includes a first hole and a second hole. The first hole is hinged to the U - shaped plate 12 through a shaft pin, and the second hole is fixed to the U - shaped plate 12 through a bolt 11.

[0061] The grip - rod connecting frame 5 and the U - shaped plate 12 can always be hinged, and the bolt 11 can be set according to different usage occasions. When cleaning denser sediment, the bolt 11 is installed; if cleaning thin mud, the bolt 11 is not installed.

[0062] The preferred solution is as Figure 8 shown in the figure. The upper edge of the baffle 9 is connected to the top edge of the window 8 through a shaft pin; a wedge - shaped blade 13 is provided at the bottom edge of the cleaning bucket 2. The wedge - shaped blade 13 can facilitate the cleaning bucket 2 to be easily inserted into the sediment.

[0063] In the preferred solution, as Figures 9 - 10As shown, the structure of the support is improved, and the support rod mechanism is changed to an insertion rod mechanism, because the support rod 401 and the threaded tube 402 will increase the resistance with the mud and sand, making it difficult for the cleaning bucket 2 to be inserted into the mud and sand. The specific solution is as follows:

[0064] The support 4 includes an insertion rod 14, which is used to penetrate the outer wall of the cleaning barrel 2. The outer end of the insertion rod 14 is connected to a strip 15, and the strip 15 is attached to the outer wall of the cleaning barrel 2. The top of the strip 15 is bent obliquely upward to form a pressure handle 16. An arc-shaped protrusion 17 is provided at the bending part of the strip 15. The arc-shaped protrusion 17 is hinged to the outer wall of the cleaning barrel 2, and the pressure handle 16 is connected to the outer wall of the cleaning barrel 2 through a spring 18.

[0065] The support rod mechanism is changed to an insertion rod mechanism, and the strip plate 15 is a flat structure, which occupies a small space and thus has a small resistance. The driving structure is moved upward to the upper part of the cleaning bucket 2, that is, the pressing handle 16, the spring 18 and the arc-shaped protrusion 17 are moved upward. The pressing handle 16, the spring 18 and the arc-shaped protrusion 17 are not easy to contact too much mud and sand, which helps to reduce resistance. On the contrary, if the pressing handle 16, the spring 18 and the arc-shaped protrusion 17 are set at the lower part of the cleaning bucket, the movement resistance of the cleaning bucket will increase.

[0066] In addition, the insertion rod 14 is more convenient to operate, and the staff can just pry open the insertion rod 14.

[0067] Because the movement track of the insertion rod 14 is arc-shaped, the insertion rod 14 should be made as short as possible, and the diameter of the through hole matched with the insertion rod 14 should be appropriately larger.

[0068] In a preferred embodiment, the method for cleaning the sediment in the inspection well comprises the following steps:

[0069] When the siltation in the inspection well is dense, the operation steps are as follows:

[0070] S1: According to the length of the inspection well 7, the number of sub-grips 101 is selected, and a plurality of sub-grips 101 are assembled to form a grip 1;

[0071] In the above steps, ensure that the handle 1 is fixedly connected to the handle connecting frame 5 so that the handle 1 cannot rotate;

[0072] S2: Check the position of the revolving door 3 to ensure that the revolving door 3 is placed on the support rod 401 or the insertion rod 14 of the bracket 4;

[0073] S3: The operator holds the handle 1 and lowers the cleaning bucket 2 into the inspection well 7;

[0074] S4: Using inertia, insert the cleaning bucket 2 downward into the mud and sand in the inspection well 7; if the insertion depth is not enough, use a hammer to knock the top of the grip rod 1;

[0075] S5: When the insertion depth of the cleaning bucket 2 is appropriate, lift the cleaning bucket 2 upward;

[0076] S6: When the cleaning bucket 2 reaches the ground, release the supporting member 4 to make the rotary door piece 3 rotate downward, so that the sediment is discharged, and the operation is completed;

[0077] When the silt in the inspection well is relatively sparse or when it is necessary to clean the thin mud in the inspection well, the operation steps are as follows:

[0078] S1: According to the length of the inspection well 7, select the number of sub-grip rods 101, and assemble multiple sub-grip rods 101 to form a grip rod 1.

[0079] In the above steps, ensure that the grip rod 1 is hinged to the grip rod connecting frame 5 so that the grip rod 1 can rotate;

[0080] S2: Check the position state of the rotary door piece 3 to ensure that the rotary door piece 3 is placed on the support rod 401 or the insertion rod 14 of the support member 4;

[0081] S3: The operator holds the grip rod 1 and lowers the cleaning bucket 2 into the inspection well 7;

[0082] S4: Shake the cleaning bucket 2 to make it swing, and let the thin mud enter the cleaning bucket 2 from the top of the cleaning bucket 2;

[0083] S5: Lift the cleaning bucket 2 upward;

[0084] S6: When the cleaning bucket 2 reaches the ground, rotate the cleaning bucket 2 to pour out the thin mud, and the operation is completed.

[0085] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present invention.
