Description

Technical Field

[0001] This invention relates to the field of sludge sampling technology, specifically to a detection and sampling device for sedimented sludge in a smart water plant. Background Technology

[0002] The sludge sampling and testing device is used for sludge sampling in sedimentation tanks of smart water plants. Constructed entirely of corrosion-resistant materials, it features a simple structure and stable operation. The device can be directly inserted into the sedimentation tank, allowing for manual sludge sample collection. It can obtain representative sludge samples to meet routine testing requirements such as moisture content and settling ratio. The device is compact, easy to assemble and disassemble, requires no external power, and is suitable for on-site manual sampling. Operation is intuitive and reliable. This type of sampling device includes, but is not limited to, sludge samplers, deep-water samplers, and columnar samplers.

[0003] Existing manual samplers require sampling layer by layer, one at a time, making it impossible to continuously sample different layers of sludge simultaneously. This increases the number of sampling attempts and reduces sampling efficiency. Furthermore, automatic samplers typically use pumps for power, generating significant suction that can cause a sudden decrease in the amount of sludge at different layers. This allows sludge from other layers to fill in, leading to sample mixing and decreased sampling accuracy. Additionally, the expensive equipment increases sampling costs. Summary of the Invention

[0017] 2. This invention, through the coordinated operation of the suction mechanism, the suction generating mechanism, and the control mechanism, can automatically complete the continuous suction of sludge. Due to the limitation of the suction port, the movable plug cannot move suddenly, thus ensuring the smooth suction of sludge. This avoids the sudden loss of sludge, which could lead to the filling of other layers of sludge, thereby preventing sludge mixing and improving the accuracy of sludge sample collection. At the same time, compared with automatic collection devices, this device has a simple structure and lower cost, further reducing the cost of sample collection.

[0018] 3. The present invention can be assembled according to different sludge depths by splicing the sludge suction mechanism and the suction generating mechanism, thereby adapting to different sedimentation sludge depths in different smart water plants, thus improving the adaptability of the device and thus improving its practicality.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see the appendix Figure 1 - Appendix Figure 8 This invention provides a smart water plant sedimentation sludge detection and sampling device, including a suction mechanism 1, a suction generating mechanism 2 at the top of the suction mechanism 1, the suction mechanism 1 for entering the sludge, the suction generating mechanism 2 for providing power for extracting the sludge, a control mechanism 3 inside the bottom of the suction mechanism 1 for opening the suction mechanism 1, and an upper exhaust mechanism 4 at the top of the outer side of the suction generating mechanism 2 for venting air when the suction generating mechanism 2 is extracting sludge.

[0030] The sludge suction mechanism 1 includes multiple mounting jackets 101, which provide installation positions and can suck up sludge. Multiple suction ports 102 are provided at the bottom of the outer wall of each mounting jacket 101, allowing sludge to easily enter. A protective cover 103 is fixedly connected to the top of the inner part of each mounting jacket 101, providing installation space and preventing sludge from entering. A return spring 104 is installed inside the protective cover 103, and a limit ring 105 is slidably connected inside the protective cover 103, serving a limiting function. A connecting ring 106 is fixedly connected to the bottom of the limit ring 105, and a blocking ring is fixedly connected to the bottom of the connecting ring 106. 107. The connecting ring 106 can connect to the blocking ring 107. Under the push of the return spring 104, the blocking ring 107 can be kept blocking the suction port 102, thereby preventing sludge from entering or being discharged. The inner side of the blocking ring 107 is fixedly connected to the mounting bracket 108. The mounting bracket 108 can move upward under the push of the control mechanism 3, thereby driving the blocking ring 107 to move, so that the blocking ring 107 will no longer block the suction port 102. One end of the return spring 104 is fixedly connected to the inner top of the protective cover 103, and the other end of the return spring 104 is fixedly connected to the bottom of the limit ring 105. The outer side of the connecting ring 106 is slidably connected to the protective cover 103. At the bottom, the outer wall of the blocking ring 107 is slidably connected to the inside of the mounting jacket 101. When the suction mechanism 1 extracts sludge, the suction generating mechanism 2 first generates suction inside the suction mechanism 1. When the moving push rod 307 moves upward, it can drive the limiting disc 306 to move upward, and the limiting disc 306 can push the mounting bracket 108 to move upward. When the mounting bracket 108 moves upward, it can drive the blocking ring 107 to move upward, thereby driving the connecting ring 106 and the limiting ring 105 to move upward. The limiting ring 105 compresses the return spring 104. After the blocking ring 107 moves upward, the suction port 102 will no longer be blocked. The obstruction ring 107 blocks the suction. Because the suction generating mechanism 2 generates suction inside the suction mechanism 1, when the suction port 102 is not blocked by the obstruction ring 107, the sludge will enter the interior of the mounting jacket 101 and the interior of the suction generating mechanism 2. When the suction generating mechanism 2 no longer generates suction, the reaction force of the return spring 104 can push the limit ring 105 to move downward, thereby driving the connecting ring 106 to move downward, and then driving the obstruction ring 107 to move downward, so that the obstruction ring 107 can block the suction port 102 again, thereby preventing the sludge from entering the interior of the mounting jacket 101 and the air cylinder 201.

[0031] The suction generating mechanism 2 includes multiple air cylinders 201. Each air cylinder 201 provides an installation position. The bottom of each air cylinder 201 is threadedly connected to the inside of the top of the mounting sleeve 101. An internal hexagonal threaded ring 202 is threadedly connected to the top of the air cylinder 201. The internal hexagonal threaded ring 202 can be threaded into the air cylinder 201 and can be fixed or removed via an internal hexagonal plate. A suction spring 203 is installed inside each air cylinder 201. A movable plug 204 is slidably connected inside each air cylinder 201. When the movable plug 204 moves upward, it generates suction inside the suction mechanism 1. A push rod 205 is fixedly connected to the top of the movable plug 204. A rotating frame 206 is rotatably connected to the outside of each air cylinder 201, providing an installation position. A push rod 207 is slidably connected to the middle of the frame 206. One end of the push rod 207 is fixedly connected to a limit plate 208, and the other end of the push rod 207 is fixedly connected to a round handle 209. After the push rod 207 moves above the air cylinder 201, it can push the push rod 205 downward by pressing the round handle 209, and push the movable plug 204 downward, thereby allowing the control mechanism 3 to discharge gas. Since the control mechanism 3 cannot suck in gas and sludge, and the suction port 102 is blocked by the blocking ring 107, the movable plug 204 will not move upward under the tension of the suction spring 203 under the action of air pressure. The top of the uppermost air cylinder 201 is threadedly connected to a threaded connecting pipe 5, and one end of the suction spring 203 is fixedly connected to the inner... The bottom of the hexagonal external thread ring 202 and the other end of the suction spring 203 are fixedly connected to the top of the movable plug 204. When sampling different sludge layers according to the required sludge depth, first screw the tops of multiple air cylinders 201 into the bottoms of multiple mounting sleeves 101, and position the control mechanism 3 inside the top of the air cylinders 201. Before screwing the multiple air cylinders 201 into the bottoms of the multiple mounting sleeves 101, first rotate the rotating frame 206 to the top of the air cylinders 201 and press the round handle 209 downward, thereby driving the push rod 207 and the limiting plate 208 to move downward and pushing the push rod 205 downward. Therefore, the movable plug 204 can be driven downward. Due to the setting of the control mechanism 3, when the movable plug 204 moves downward, it will pass through... Control mechanism 3 discharges the gas inside air cylinder 201. Since control mechanism 3 can only discharge and not intake air, the movable plug 204 will not move upward under the pull of suction spring 203 due to air pressure. At this time, multiple devices can be spliced ​​together. When the bottom movable push rod 307 contacts the bottom of the sewage tank, as the mounting sleeve 101 continues to move downward, the corresponding movable push rod 307 and limiting disc 306 move upward. At this time, the bottom blocking ring 107 slides upward away from the suction port 102, allowing sludge to enter from the suction port 102 and gradually balance the air pressure inside the mounting sleeve 101 and air cylinder 201. At this time, under the pulling force of suction spring 203, the movable plug 204 can be driven to move upward.The gas generated by the upward movement of the movable plug 204 is discharged through the upper exhaust mechanism 4, continuously creating suction in the space below the movable plug 204 and transmitting this suction to the interior of the mounting sleeve 101. This suction then draws in sludge through the suction port 102, simultaneously moving the push rod 205 upward. The push rod 205 then pushes the upper movable push rod 307 upward, causing the upper air cylinder 201 and mounting sleeve 101 to generate suction. This process is repeated to gradually activate multiple sampling devices for sludge sampling.

[0032] The control mechanism 3 includes multiple fixed cylinders 301. Each fixed cylinder 301 provides an installation position and penetrates the top of the air cylinder 201 and the interior of the internal hexagonal threaded ring 202. The top of each fixed cylinder 301 is fixedly connected to the bottom of the mounting sleeve 101. A sliding ring 302 is slidably connected inside each fixed cylinder 301, serving a limiting function. An exhaust movable cylinder 303 is fixedly connected to the bottom of the sliding ring 302. The exhaust movable cylinder 303 can move downwards under the pressure of gas. Multiple exhaust holes 304 are provided on the outer wall of the exhaust movable cylinder 303, allowing gas to be discharged. A push spring 305 is fitted around the outside of the exhaust movable cylinder 303, driving the sliding ring 302 upwards. The exhaust cylinder 303 can be moved upwards, thereby blocking the exhaust port 304 with the fixed cylinder 301 and preventing gas from being sucked in. A movable push rod 307 is slidably connected to the bottom of the exhaust cylinder 303, and a limiting disc 306 is fixedly connected to the top of the movable push rod 307. The movable push rod 307 can be pushed upwards, thereby moving the limiting disc 306 upwards and the mounting bracket 108 upwards. A through hole 308 is provided at the top of the fixed cylinder 301, allowing the limiting disc 306 to move upwards smoothly. One end of the push spring 305 is fixedly connected to the bottom of the sliding ring 302, and the other end of the sliding ring 302 is fixedly connected to the inside of the fixed cylinder 301. The limiting disc 306... 6 is installed inside the exhaust cylinder 303. When the lowest device contacts the bottom of the sewage tank, the moving push rod 307 first contacts the bottom of the tank. As the threaded connecting pipe 5 is pressed down, it can drive the lowest mounting sleeve 101 to move downward. Correspondingly, the moving push rod 307 and the limiting disc 306 will move upward and move out of the fixed cylinder 301 through the through hole 308, so that the limiting disc 306 contacts the mounting bracket 108 and pushes the mounting bracket 108 to move upward, and drives the blocking ring 107 to slide, so that the blocking ring 107 no longer blocks the suction port 102. When the movable plug 204 moves downward to exhaust gas, the gas will push the sliding ring 302 and the exhaust cylinder 303 to move downward. After the vent 304 on the 03 moves out of the interior of the fixed cylinder 301, gas can be discharged through the vent 304. When the suction generating mechanism 2 stops sucking up gas, it can push the sliding ring 302 and the venting cylinder 303 upward under the action of the push spring 305, and can make the vent 304 move back into the interior of the fixed cylinder 301, thereby blocking the vent 304. At this time, when the movable plug 204 moves upward to start sucking up air, the venting cylinder 303 will not move upward because the sliding ring 302 is blocked, thus preventing gas from entering the vent 304. At this time, sludge can only enter from the suction port 102. At the same time, when the blocking ring 107 blocks the suction port 102,When the vent 304 is also blocked by the fixed cylinder 301, the movable plug 204 will not move upward under the pulling force of the suction spring 203. Through the coordinated operation of the suction mechanism 1, the suction generating mechanism 2, and the control mechanism 3, the device can be inserted into the sludge and then opened, thereby using suction to suck in the sludge. The device can be assembled or disassembled according to the depth of the sludge, enabling continuous suction of different layers of sludge. This eliminates the need for single-layer sampling, improving sampling efficiency and device adaptability.

[0033] The upper exhaust mechanism 4 includes multiple fixed vent seats 401, which provide installation positions. One end of the fixed vent seat 401 is fixedly connected to the outside of the air cylinder 201, and the other end of the fixed vent seat 401 is fixedly connected to a vent pipe 403. Multiple vent holes 402 are opened on the outside of the fixed vent seat 401 to facilitate the discharge of gas. A movable outer sleeve 404 is slidably connected to the outside of the fixed vent seat 401. The movable outer sleeve 404 slides towards the air cylinder 201 to remove sludge and can cover the fixed vent seat. The exterior of the movable outer sleeve 401 is sealed to block the vent 402, thereby preventing gas or sludge from entering the interior of the air cylinder 201. A return spring 405 is installed inside the movable outer sleeve 404. The return spring 405 can pull the movable outer sleeve 404 back to its original position when no gas is generated inside the air cylinder 201, allowing the movable outer sleeve 404 to re-cover the exterior of the fixed vent seat 401. One end of the return spring 405 is fixedly connected to the interior of the movable outer sleeve 404, and the other end is fixedly connected to the side of the fixed vent seat 401. Near one end of the venting connecting pipe 403, the interior of the fixed vent seat 401 is connected to the interior of the air cylinder 201. A return spring 405 is sleeved on the outside of the venting connecting pipe 403. When the movable plug 204 moves upward, the gas in the air cylinder 201 enters the interior of the venting connecting pipe 403 through the fixed vent seat 401, thereby pushing the movable outer sleeve 404 away from the air cylinder 201 and stretching the return spring 405. When the movable outer sleeve 404 moves outside the fixed vent seat 401, exposing the vent hole 402... The gas inside the air cylinder 201 will be discharged through the vent 402. Since the vent 402 generates gas outward, no sludge will enter the interior of the air cylinder 201. When the air cylinder 201 stops venting, the reaction force of the return spring 405 can drive the movable outer sleeve 404 to return to its original position. The movable outer sleeve 404 can push the sludge down and cover the outside of the fixed vent seat 401, thereby preventing the vent 402 from venting and also preventing sludge from entering the space above the movable plug 204 inside the air cylinder 201.

[0034] Working principle: When the sludge suction mechanism 1 extracts sludge, the suction generating mechanism 2 first generates suction inside the suction mechanism 1. When the moving push rod 307 moves upward, it drives the limiting disc 306 upward, which in turn pushes the mounting bracket 108 upward. When the mounting bracket 108 moves upward, it drives the blocking ring 107 upward, which in turn drives the connecting ring 106 and the limiting ring 105 upward. The limiting ring 105 compresses the return spring 104. After the blocking ring 107 moves upward, the suction port 102 is no longer blocked by the blocking ring 107. Due to the suction force... The suction mechanism 2 generates suction inside the suction mechanism 1. Therefore, when the suction port 102 is not blocked by the blocking ring 107, the sludge will enter the interior of the mounting jacket 101 and the interior of the suction generating mechanism 2. When the suction generating mechanism 2 no longer generates suction, the return spring 104 will push the limit ring 105 downward, thereby driving the connecting ring 106 downward, which in turn drives the blocking ring 107 downward, so that the blocking ring 107 can block the suction port 102 again, thereby preventing sludge from entering the interior of the mounting jacket 101 and the air cylinder 201.

[0035] When sampling different sludge layers according to the required sludge depth, first screw the tops of multiple air cylinders 201 into the bottoms of multiple mounting sleeves 101, so that the control mechanism 3 is inside the top of the air cylinders 201. Before screwing the multiple air cylinders 201 into the bottoms of the multiple mounting sleeves 101, first rotate the rotating frame 206 to the top of the air cylinders 201 and press the round handle 209 downward, thereby driving the push rod 207 and the limiting plate 208 to move downward and pushing the push rod 205 downward. Therefore, it can drive the movable plug 204 downward. Due to the setting of the control mechanism 3, when the movable plug 204 moves downward, it will discharge the gas inside the air cylinder 201 through the control mechanism 3. Since the control mechanism 3 can only discharge and not inhale, under the action of air pressure, the movable plug 204 will not move upward under the pull of the suction spring 203. At this time, multiple devices can be spliced. When the bottommost moving push rod 307 contacts the bottom of the sewage tank, due to the installation As the outer casing 101 continues to move downwards, the corresponding moving push rod 307 and limiting disc 306 move upwards. At this time, the bottommost blocking ring 107 slides upwards away from the suction port 102, allowing sludge to enter from the suction port 102 and gradually balance the air pressure inside the outer casing 101 and the air cylinder 201. Under the pulling force of the suction spring 203, the movable plug 204 can be driven upwards, and the gas generated by the upward movement of the movable plug 204 can be discharged through the upper exhaust mechanism 4. This continuously generates suction in the space below the movable plug 204, and transmits the suction to the interior of the outer casing 101, allowing sludge to be sucked in through the suction port 102. At the same time, it drives the push rod 205 upwards and pushes the upper moving push rod 307 upwards, thereby generating suction between the upper air cylinder 201 and the outer casing 101. This process is repeated to gradually open multiple sampling devices for sludge sampling.

[0036] When the lowest device contacts the bottom of the sewage tank, the movable push rod 307 first contacts the bottom of the tank. As the threaded connecting pipe 5 is pressed down, the lowest mounting sleeve 101 can move downwards. Correspondingly, the movable push rod 307 and the limiting disc 306 will move upwards and move out of the interior of the fixed cylinder 301 through the through hole 308, allowing the limiting disc 306 to contact the mounting bracket 108 and push the mounting bracket 108 upwards, causing the blocking ring 107 to slide, so that the blocking ring 107 no longer blocks the suction port 102. When the movable plug 204 moves downwards to vent, the gas will push the sliding ring 302 and the venting movable cylinder 303 downwards. After the vent hole 304 on the venting movable cylinder 303 moves out of the interior of the fixed cylinder 301, the gas can pass through... When the exhaust port 304 is discharged, and the suction generating mechanism 2 stops sucking up gas, it can push the sliding ring 302 and the exhaust movable cylinder 303 to move upward under the action of the push spring 305, and can move the exhaust port 304 back into the fixed cylinder 301, thereby blocking the exhaust port 304. At this time, when the movable plug 204 moves upward to start sucking up gas, the exhaust movable cylinder 303 will not move upward because the sliding ring 302 is blocked, and gas will not enter the exhaust port 304. At this time, the sludge can only enter from the suction port 102. At the same time, when the blocking ring 107 blocks the suction port 102 and the exhaust port 304 is also blocked by the fixed cylinder 301, the movable plug 204 will not move upward under the pulling force of the suction spring 203.

[0037] When the movable plug 204 moves upward, the gas in the air cylinder 201 enters the air connection pipe 403 through the fixed vent seat 401, thereby pushing the movable outer sleeve 404 away from the air cylinder 201 and stretching the return spring 405. When the movable outer sleeve 404 moves outside the fixed vent seat 401 and exposes the vent hole 402, the gas inside the air cylinder 201 is discharged through the vent hole 402. Since the vent hole 402 generates gas outward, no sludge enters the air cylinder 201. When the air cylinder 201 stops venting, the reaction force of the return spring 405 drives the movable outer sleeve 404 to return to its original position, and the movable outer sleeve 404 pushes the sludge down and covers the outside of the fixed vent seat 401, thereby preventing the vent hole 402 from venting and also preventing sludge from entering the space above the movable plug 204 inside the air cylinder 201.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
