Description

Technical Field

[0001] This invention relates to the field of drainage culverts, and more particularly to a defect detection device and method for underwater drainage culverts with high flow velocity. Background Technology

[0002] Urban drainage culverts (covered culverts) are crucial infrastructure in the urban drainage and flood control system, playing a vital role in ensuring the orderly collection, transportation, and treatment of urban sewage and maintaining the city's daily operations. To ensure the effectiveness of drainage culverts, maintenance and management units regularly perform maintenance and clean the accumulated silt inside the culverts. Currently, the most basic method is manual labor, supplemented by equipment, to enter the culverts for inspection.

[0003] However, in recent years, accidents have frequently occurred due to personnel entering the box culvert for inspection. This is partly due to insufficient oxygen in the underground box culvert, and partly due to sudden heavy rain in some areas that prevented personnel from evacuating in time. Improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a defect detection device and method for underwater drainage culverts with high flow velocity, so as to solve the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A defect detection device for underwater drainage culverts with high flow velocity includes a silt detection mechanism and a floating mechanism. The floating mechanism is connected to the silt detection mechanism via a steel wire rope and is used to move the silt detection mechanism.

[0007] Preferably, the sludge detection mechanism includes: a connecting plate; a support rod, wherein a plurality of support rods are fixedly mounted on the bottom surface of the connecting plate; a support sleeve, wherein a plurality of support sleeves are fixedly mounted on the support rods; and a V-shaped baffle, wherein the V-shaped baffle is fixedly connected to the support sleeves.

[0008] Preferably, the sludge detection mechanism further includes: a rotating shaft, wherein the bottom end of the support rod is fixedly provided with the rotating shaft; and a roller, wherein the roller is rotatably sleeved on the rotating shaft.

[0009] Preferably, the floating mechanism includes: a main float plate, which is fixedly connected to a connecting plate by a steel wire rope; and auxiliary float plates, with multiple auxiliary float plates fixedly disposed on the bottom surface of the main float plate.

[0010] Preferably, the floating mechanism further includes: a mounting groove, wherein the top surface of the main float plate has a mounting groove; a GPS coordinate transmitter, wherein the GPS coordinate transmitter is disposed in the mounting groove; a limiting ring, wherein the limiting ring is fitted against the inner wall of the mounting groove and is fixed to the top of the GPS coordinate transmitter; a first sealing plug, wherein the first sealing plug is threadedly connected to the mounting groove; and a silicone sealing ring, wherein a silicone sealing ring is disposed between the first sealing plug and the limiting ring.

[0011] Preferably, the floating mechanism further includes a handle, wherein the handle is fixed to the top of the first sealing plug.

[0012] Preferably, the system further includes a triggering mechanism, which comprises: a base, wherein the bottom surface of any one of the auxiliary floats is fixedly provided with a base; a sliding groove, wherein a sliding groove is formed inside the base; a second sealing plug, wherein a second sealing plug is slidably connected inside the sliding groove; a push plate, wherein the top of the push plate is slidably connected to a slide rail, and the slide rail is fixedly connected to the bottom surface of the auxiliary float; a connecting rod, wherein one end of the connecting rod is fixedly connected to the push plate, and the other end of the connecting rod is fixedly connected to the second sealing plug; a connecting spring, wherein one end of the connecting spring is fixedly connected to the push plate, and the other end of the connecting spring is fixedly connected to the base; and a waterproof controller, wherein the waterproof controller is fixedly connected to the inner wall of the sliding groove, and the waterproof controller is wirelessly connected to a GPS coordinate transmitter, and a self-reset control button is provided on the side of the waterproof controller near the second sealing plug.

[0013] Preferably, a plurality of pressure blocks are fixed on the top surface of the connecting plate.

[0014] The beneficial effects of this invention are:

[0015] By placing this device inside a drainage culvert, the main float plate floats on the water surface, and the support rod is inserted into the silt. Driven by the high-velocity water flow, the main float plate moves via a steel wire rope and a connecting plate. When it moves to a deeper part of the silt, the support rod penetrates the silt more deeply, and more V-shaped baffles are inserted into the silt to obstruct the movement of the connecting plate, causing the main float plate to stop moving. The device then uses the coordinates sent by the GPS coordinate transmitter to locate the current position of the main float plate and clean the silt. This invention eliminates the need for manual entry into the drainage culvert for extended inspections. It can automatically detect areas with significant silt accumulation inside the drainage culvert and notify personnel to come and clean it, ensuring high safety. Attached Figure Description

[0022] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0023] Specific embodiments of the present invention are described below with reference to the accompanying drawings. Example 1

[0024] like Figure 1-5 As shown, a defect detection device for underwater drainage culverts with high flow velocity includes...

[0025] The silt detection mechanism is connected to the silt detection mechanism via a steel wire rope 6. The floating mechanism is used to move the silt detection mechanism.

[0026] The silt detection mechanism includes: a connecting plate 5, with multiple pressure blocks 4 fixed on the top surface of the connecting plate 5; a support rod 2, with multiple support rods 2 fixed on the bottom surface of the connecting plate 5; a support sleeve 8, with multiple support sleeves 8 fixedly sleeved on the support rod 2; a V-shaped baffle 1, which is fixedly connected to the support sleeve 8; a rotating shaft 9, which is fixedly sleeved at the bottom end of the support rod 2; and a roller 3, which is rotatably sleeved on the rotating shaft 9.

[0027] The floating mechanism includes: a main float plate 15, which is fixedly connected to a connecting plate 5 by a steel wire rope 6; auxiliary float plates 7, with multiple auxiliary float plates 7 fixedly mounted on the bottom surface of the main float plate 15; a mounting groove 10, with a mounting groove 10 opened on the top surface of the main float plate 15; a GPS coordinate transmitter 14, which is disposed in the mounting groove 10; a limiting ring 13, which fits against the inner wall of the mounting groove 10 and is fixedly mounted on the top of the GPS coordinate transmitter 14; a first sealing plug 16, which is threadedly connected to the mounting groove 10; a silicone sealing ring 12, which is disposed between the first sealing plug 16 and the limiting ring 13; and a handle 11, with a handle 11 fixedly mounted on the top of the first sealing plug 16.

[0028] Working principle: When in use, the device is placed in the drainage culvert, so that the main float 15 floats on the water surface. The support rod 2 is inserted into the silt at the bottom of the drainage culvert, and the roller 3 is in contact with the bottom of the drainage culvert. Driven by the high-speed water flow, the main float 15 moves against the resistance of the silt by the steel wire rope 6, which drives the connecting plate 5 and the support rod 2. When it moves to a deeper part of the silt, the support rod 2 is inserted into the silt more deeply, and more V-shaped baffles 1 are inserted into the silt, which increases the resistance of the connecting plate 5 and the support rod 2, causing the main float 15 to stop moving. The staff can reach the position of the main float 15 at this time by using the coordinate position sent by the GPS coordinate transmitter 14 to carry out the silt cleaning work.

[0029] Rotate the first sealing plug 16 to disengage it from the mounting groove 10, and the GPS coordinate transmitter 14 can be removed from the mounting groove 10. Example 2

[0030] like Figure 1-5 As shown, while other parts are the same as in Embodiment 1, the difference between this embodiment and Embodiment 1 is that it also includes a triggering mechanism, which includes: a base 21, on the bottom surface of any auxiliary float 7; a slide groove 18, inside the base 21; a second sealing plug 17, slidably connected inside the slide groove 18; a push plate 22, the top of the push plate 22 is slidably connected to the slide rail 25, and the slide rail 25 is fixedly connected to the bottom surface of the auxiliary float 7; a connecting rod 26, one end of the connecting rod 26 is fixedly connected to the push plate 22, and the other end of the connecting rod 26 is fixedly connected to the second sealing plug 17; a connecting spring 23, one end of the connecting spring 23 is fixedly connected to the push plate 22, and the other end of the connecting spring 23 is fixedly connected to the base 21; and a waterproof controller 19, which is fixedly connected to the inner wall of the slide groove 18 and wirelessly connected to the GPS coordinate transmitter 14. A self-reset control button 20 is provided on the side of the waterproof controller 19 near the second sealing plug 17.

[0031] Working principle: When the main float 15 flows with the water flow, the water flow cannot push the push plate 22 to move, so the push plate 22 cannot press the self-reset control button 20 through the connecting rod 26 and the second sealing plug 17. When the device moves to a deeper part of the silt, the main float 15 stops moving due to the resistance of the silt. The high-velocity water flow impacts the push plate 22, driving the push plate 22 to move. The push plate 22 then drives the second sealing plug 17 to move through the connecting rod 26, causing the second sealing plug 17 to press the self-reset control button 20. This causes the waterproof controller 19 to control the GPS coordinate transmitter 14 to start sending the coordinate position to the staff. The staff can then reach the site to clean the silt based on the coordinate position.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
