Description
Technical Field
[0001] The invention relates to the technical field of water pipe leakage detection, and in particular to an anti-seepage detection device for a sewage drainage pipe. Background Art
[0002] During the construction and production of mines, atmospheric precipitation, surface water (rivers, lakes, seas, reservoirs, etc.) and groundwater and other sewage may flow into the mine through various channels. The water flowing into the mine is collectively referred to as mine water inflow. The amount of mine water inflow and the inflow state directly affect the construction and production of the mine. During the construction and production of mines, this water needs to be effectively discharged to ensure the life safety of mine workers and the normal safe production of the mine. The mine drainage system consists of multiple parts, including water pumps, drainage pipelines, power distribution equipment, water tanks and other facilities.
[0003] During the construction of the mine drainage system, the drainage pipes need to be buried underground. In order to ensure that the drainage pipes will not leak when the drainage is carried out after the construction is completed, the drainage pipes need to be tested for leakage before installation to ensure the airtightness of the drainage pipes used. When testing the drainage pipes, the existing detection devices often use the method of sealing and pressurizing both sides of the pipes to detect whether the drainage pipes are leaking. However, since the inside of the pipes needs to be filled with water during the test, the sealing during the test cannot be guaranteed and it is not easy to observe the leakage points. Summary of the invention

Before the limiting plate abuts against the drain pipe, the detecting member moves along the first direction toward the side close to the drain pipe to drive the limiting plate to move synchronously, and the size of the limiting plate in the second direction is larger than the size of the drain pipe in the second direction. After the limiting plate abuts against the drain pipe, the detecting member can move along the first direction relative to the corresponding limiting plate, the detecting member can extend into the drain pipe, and can expand along the second direction toward the side away from the central axis of the drain pipe.

DETAILED DESCRIPTION
[0028] 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.
[0029] An embodiment of a sewage drainage pipe anti-seepage detection device of the present invention is as follows Figures 1 to 10 shown.
[0030] A sewage drainage pipe anti-seepage detection device includes a bracket 100 and two detection mechanisms 200. A drainage pipe 300 is arranged on the bracket 100 along a horizontal direction, and the axial direction of the drainage pipe 300 is referred to as a first direction. The two detection mechanisms 200 are symmetrically arranged on the bracket 100 along a second direction, and the second direction is perpendicular to the first direction, and the second direction is the radial direction of the drainage pipe 300. The detection mechanism 200 includes a detection member 210 and a stop member 220. The two detection members 210 are both installed on the bracket 100 and located on both sides of the drainage pipe 300 along the first direction. The detection member 210 can move along the first direction. A plurality of detection sections are sequentially arranged in the drainage pipe 300 along the first direction, and in each detection, the size of the two detection members 210 in the first direction is equal to the size of one detection section in the first direction.
[0031] A water inlet 211 is provided in the middle of the detection member 210 for passing water between the two detection members 210. A pressure sensor is provided on each detection member 210, and the pressure sensor is used to monitor the change of water pressure after water passes between the two detection members 210, and transmit the sensed pressure parameters to the external detection system. The detection member 210 is elastic and always has a tendency to expand along the second direction toward the side away from the central axis of the drain pipe 300. The detection member 210 has a vortex channel 212 parallel to the second direction, and the vortex channel 212 is defined by two side plates 213. The two side plates 213 are symmetrically arranged in the second direction and fixedly connected, and the two side plates 213 are an integrally formed structure. The two circles of side plates 213 adjacent to each other along the second direction are always close to each other, and the side plates 213 are coated with rubber 214.
[0032] The limit member 220 is installed on the bracket 100. In the initial state, the diameter of the detection member 210 is smaller than the diameter of the drain pipe 300, and the limit member 220 can limit the detection member 210 from expanding along the second direction toward the side away from the central axis of the drain pipe 300, so that the detection member 210 can enter the drain pipe 300. When the detection member 210 extends into the drain pipe 300, the limit member 220 allows the detection member 210 to expand along the second direction toward the side away from the central axis of the drain pipe 300, so that the detection member 210 can abut against the inner circumferential wall of the drain pipe 300.
[0033] In this embodiment, two detection mechanisms 200 are arranged on the bracket 100. When in use, the drain pipe 300 is first placed on the bracket 100, and then the two detection mechanisms 200 are brought close to each other along the first direction. Since the detection member 210 is installed on the corresponding limit member 220 in the initial state, the detection member 210 cannot expand along the second direction to the side away from the central axis of the drain pipe 300 under the restriction of the limit member 220, and the diameter of the detection member 210 is smaller than the diameter of the drain pipe 300, so the detection member 210 can extend into the drain pipe 300. When the detection member 210 extends into the drain pipe 300, the detection member 210 will expand along the second direction to the side away from the central axis of the drain pipe 300, so that the detection member 210 is tightly attached to the inner circumferential wall of the drain pipe 300 to adapt to drain pipes 300 of different diameters, and the side plate 213 located at the outermost circle of the detection member 210 is sealed and connected to the inner circumferential wall of the drain pipe 300 through the rubber 214 on the side plate 213.
[0034] Then, the two detection members 210 are driven to move until the size of the two detection members 210 in the first direction is equal to the size of a detection section in the first direction, and then water is injected into the water inlet 211 to pressurize the detection section to detect the leakage of the detection section, and the pressure change of the pressure sensor is observed. If the leakage pressure does not change, there is no leakage problem in this section of the drain pipe 300, and the pressure change indicates that there is leakage in this section of the drain pipe 300. After water injection, the water flow will apply a certain pressure to the two detection members 210, so that the two circles of side plates 213 arranged adjacent to each other along the second direction are further pressed together to prevent water from leaking from the detection member 210. After detection, the two detection members 210 are driven to move to the location of the next detection section, and the drain pipe 300 is detected in sections. The water-passing area can be adjusted with the movement, and only a small amount of water is needed to detect the leakage of the entire drain pipe 300, which can not only save water resources, but also use the pressure sensor for detection, and can monitor the leakage of the drain pipe 300 in real time by sensing the change of water pressure, and more accurately determine the location of the leakage on the drain pipe 300.
[0035] In this embodiment, the limiting member 220 includes a limiting plate 221. In the initial state, the limiting plate 221 is arranged away from the drain pipe 300 in the first direction and does not abut against the drain pipe 300. The detecting member 210 is installed in the limiting plate 221. The limiting plate 221 limits the corresponding detecting member 210 to expand along the second direction toward the side away from the central axis of the drain pipe 300. Before the limiting plate 221 abuts against the drain pipe 300, the detecting member 210 moves along the first direction toward the side close to the drain pipe 300, which can drive the limiting plate 221 to move synchronously through friction. The size of the limiting plate 221 in the second direction is larger than the size of the drain pipe 300 in the second direction, so that after the limiting plate 221 abuts against the drain pipe 300, the detecting member 210 can be separated from the limiting plate 221 corresponding to the detecting member 210 and move along the first direction relative to the limiting plate 221 corresponding to the detecting member 210, so that the detecting member 210 can extend into the drain pipe 300 and can expand along the second direction toward the side away from the central axis of the drain pipe 300.
[0036] Specifically, a limiting groove is provided on the limiting plate 221, and the detection member 210 is installed in the limiting groove in an initial state, and the limiting groove limits the corresponding detection member 210 to expand along the second direction toward the side away from the central axis of the drain pipe 300.
[0037] In this embodiment, the detection mechanism 200 further includes a push rod 230, which is arranged on the bracket 100 along the first direction and can move on the bracket 100 along the first direction. The push rod 230 is arranged in a one-to-one correspondence with the detection member 210, and the push rod 230 is located on a side of the corresponding detection member 210 away from the drain pipe 300 in the first direction. The push rod 230 passes through the limiting plate 221 and is fixedly connected to the corresponding detection member 210.
[0038] Furthermore, the push rod 230 is a tubular structure with a hollow interior, and an opening 231 is provided on the push rod 230 . A connecting ring 240 is fixedly connected to the middle of the detection member 210 , and the water inlet 211 is provided on the connecting ring 240 . The connecting ring 240 is fixedly connected to the push rod 230 , so that the opening 231 is connected to the water inlet 211 .
[0039] In this embodiment, a push rod 230 is provided. When in use, the push rod 230 moves to drive the detection member 210 to move synchronously, and an opening 231 is provided on the push rod 230 so that the opening 231 is connected to the water inlet 211. After water is injected into the opening 231, the water can flow from the push rod 230 through the water inlet 211 to between the two detection members 210.
[0040] In this embodiment, the detection mechanism 200 further includes a screw 250 and a push plate 260. The screw 250 is arranged on the bracket 100 along the first direction and can only rotate around the first direction on the bracket 100. The push plate 260 is slidably mounted on the bracket 100 and spirally cooperates with the screw 250. One end of the push rod 230 away from the detection member 210 in the first direction is fixedly connected to the push plate 260, so that when the screw 250 rotates around the first direction, the push plate 260 can be urged to move along the first direction, and the push rod 230 is driven to move synchronously through the push plate 260. The movement of the push rod 230 will drive the detection member 210 to move. And by adjusting the moving distance of the push plate 260, the drainage pipes 300 of different lengths can be adapted.
[0041] Specifically, the screw 250 includes a spiral section and an optical axis section, which are arranged sequentially in the first direction, and the spiral section is located on the side of the optical axis section away from the drain pipe 300 in the first direction, the push plate 260 is spirally matched with the spiral section, and the limit plate 221 is rotationally matched with the optical axis section.
[0042] By setting the spiral as a spiral section and an optical axis section, when the screw 250 rotates around the first direction, the push plate 260 will drive the push rod 230 to move synchronously through the spiral transmission, and the movement of the push rod 230 will prompt the detection member 210 to move. Since the detection member 210 is installed in the limit plate 221 in the initial state, before the limit plate 221 abuts against the drain pipe 300, the movement of the detection member 210 will drive the limit plate 221 to move synchronously through friction, and at this time, the limit plate 221 slides on the optical axis section.
[0043] In this embodiment, the bracket 100 includes two frames 110, the two frames 110 have the same structure and are symmetrically arranged along the second direction. The two detection mechanisms 200 are respectively installed on the two frames 110. The two frames 110 are rotatably connected. The push rod 230 is elastic and is a rubber tube, so that the push rod 230 can produce elastic deformation.
[0044] Specifically, a placement plate 120 is disposed on each of the two frames 110 , the drain pipe 300 is placed on the two placement plates 120 , and a binding belt 121 is disposed on each of the two placement plates 120 .
[0045] Furthermore, a positioning rod 130 is provided between each frame 110 and the placement plate 120 on the frame 110 adjacent to it in the first direction. The positioning rod 130 is provided along the first direction. The positioning rod 130 and the push plate 260 and the limit plate 221 on the same frame 110 are slidably matched, and the push plate 260 and the limit plate 221 are limited in sliding in the first direction by the positioning rod 130. Universal wheels 140 are provided at the bottom of the two frames 110 to facilitate operators to push the frames 110 to move.
[0046] Each frame 110 is provided with a motor 150, which is used to drive the screw 250 on the same frame 110 to rotate around the first direction, and the screw 250 and the placement plate 120 on the same frame 110 are rotated in coordination, so that the screw 250 can only rotate around the first direction.
[0047] Furthermore, a first elastic member 232 is disposed inside the push rod 230 . The first elastic member 232 is disposed along the first direction. Both ends of the first elastic member 232 along the first direction are fixedly connected to the push rod 230 .
[0048] In this embodiment, the first frame 110 and the second frame 110 are rotatably connected, and the push rod 230 is set to an elastic material. When in use, when the drain pipe 300 is bent, the angles of the first frame 110 and the second frame 110 are first adjusted so that the drain pipe 300 can be placed on the first frame 110 and the second frame 110. Then, the two detection members 210 are driven to move in the first direction so that the detection members 210 can enter the drain pipe 300, and when the detection member 210 passes through the curved pipe section in the drain pipe 300, each two side plates 213 arranged adjacent to each other along the second direction on the detection member 210 can be deformed along with the curved portion of the drain pipe 300, so that the detection member 210 can adapt to the shape of the curved portion of the drain pipe 300, and the two circles of side plates 213 arranged adjacent to each other along the second direction can always remain in close contact during deformation, and will not cause poor sealing due to the different linear speeds on both sides of the curved portion of the drain pipe 300 during movement, and the elasticity of the push rod 230 enables it to bend along with the detection member 210, and the elastic detection member 210 and push rod 230 can adapt to the shape of the curved portion of the drain pipe 300, realize movement in the curved portion of the drain pipe 300, and ensure the sealing of the detection member 210, thereby expanding the scope of use of the detection member 210.
[0049] In combination with the above embodiments, the specific working process is as follows:
[0050] During use, when the drain pipe 300 is a straight pipe, the drain pipe 300 is first placed on the two placement plates 120. In the initial state, the two limit plates 221 are both arranged away from the drain pipe 300 in the first direction, that is, the limit plates 221 are a certain distance away from the drain pipe 300. Then the two motors 150 are started. The motor 150 starts to drive the screw 250 to rotate, and drives the push plate 260 to move in the first direction through the screw 250. The movement of the push plate 260 will drive the corresponding push rod 230 to move, and push the detection member 210 to move through the push rod 230. At this time, the detection member 210 is installed in the limit plate 221, and will drive the limit plate 221 to move synchronously until it moves to the limit plate 221 and abuts against the end face of the drain pipe 300. Then the limit plate 221 will be restricted by the drain pipe 300 and cannot move further, so the screw 250 continues to rotate to move the detection member 210 relative to the corresponding limit plate 221, so that the detection member 210 is separated from the limit plate 221. Since the diameter of the detection member 210 in the initial state is smaller than the diameter of the drain pipe 300, the detection member 210 can extend into the drain pipe 300, and after the detection member 210 is separated from the limit plate 221, the detection member 210 will expand along the second direction toward the side away from the central axis of the drain pipe 300, so that the detection member 210 is tightly attached to the inner circumferential wall of the drain pipe 300 to adapt to drain pipes 300 of different diameters, and the side plate 213 located at the outermost circle of the detection member 210 is sealed and connected to the inner circumferential wall of the drain pipe 300 through the rubber 214 on the side plate 213.
[0051] The distance that the left detection member 210 moves in the drain pipe 300 is greater than the distance that the right detection member 210 moves in the drain pipe 300. Figure 2, and at the same time, the size of the two detection members 210 in the first direction is equal to the size of a detection section in the first direction, and then water is injected into the opening 231, and water can flow from the push rod 230 through the water inlet 211 to between the two detection members 210, and the water is injected and pressurized between the two detection members 210, and the leakage of the detection section is detected by observing the pressure change of the pressure sensor. If the leakage pressure does not change, there is no leakage problem in this section of the drain pipe 300, and the pressure change indicates that there is leakage in this section of the drain pipe 300. After water injection, the water flow will exert a certain pressure on the two detection members 210, thereby further tightening the two adjacent side plates 213 arranged along the second direction to prevent water from leaking from the detection member 210. After detection, the two detection parts 210 are driven to move to the left at the same time for a detection section distance, so that the two detection parts 210 move to the position of the next detection section, thereby realizing segmented detection of the drain pipe 300. The water flow area can be adjusted accordingly. Only a small amount of water is needed to detect the leakage of the entire drain pipe 300, which not only saves water resources, but also uses a pressure sensor for detection. It can monitor the leakage of the drain pipe 300 in real time by sensing the change of water pressure, and can more accurately determine the location of the leakage on the drain pipe 300.
[0052] When the drain pipe 300 is bent, the angles of the first frame 110 and the second frame 110 are adjusted first, so that the drain pipe 300 can be placed on the first frame 110 and the second frame 110 . Then, the two detection members 210 are driven to move in the first direction so that the detection members 210 can enter the drain pipe 300, and when the detection member 210 passes through the curved pipe section in the drain pipe 300, each of the two side plates 213 adjacently arranged along the second direction on the detection member 210 can be deformed along with the shape of the curved portion of the drain pipe 300, so that the detection member 210 can better adapt to the shape of the curved portion of the drain pipe 300, and the two circles of side plates 213 adjacently arranged along the second direction can always remain tightly attached during deformation, and will not cause poor sealing due to the different linear speeds on both sides of the curved portion of the drain pipe 300 during movement, and the elasticity of the push rod 230 enables it to bend along with the detection member 210, and the elastic detection member 210 and push rod 230 can adapt to the shape of the curved portion of the drain pipe 300, realize movement in the curved portion of the drain pipe 300, and ensure the sealing of the detection member 210, thereby expanding the scope of use of the detection member 210.
[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
