Description

Technical Field

[0001] This invention relates to the field of buried pipeline detection technology, specifically a non-contact carrier transmission connector for detecting blockages and leaks. Background Technology

[0002] Buried pipelines operate in extremely harsh underground environments for extended periods, facing multiple challenges such as corrosion from complex acidic and alkaline substances in the soil and microbial erosion. Under these conditions, existing mainstream detection sensor technologies, such as metal detection, inductive detection, and capacitive detection, all exhibit significant limitations (inductive and capacitive detectors are easily corroded), making long-term stable operation difficult. This leads to inconsistent accuracy of detection data, increased risks of false alarms and missed alarms, and significantly limited sensor lifespan, posing a severe challenge to long-term, effective, and reliable monitoring of pipeline conditions. Therefore, a non-contact carrier transmission connector for plugging blockage and leakage detection is provided to address the problems mentioned in the background. Summary of the Invention

[0003] The purpose of this invention is to solve the technical problems of existing buried pipeline detection sensors, which are prone to corrosion, have poor data accuracy, and have short service life due to direct contact with the water inside the pipeline.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This invention provides a non-contact carrier transmission connector for detecting blockages and leaks, comprising a connector structure, which includes a connector head and a connector. The connector head is inserted into the connector head to form a sealed cavity between the two. A blockage detection device is provided on the connector head inside the cavity, penetrating the inner wall of the connector head. A leak detection device is also provided inside the cavity. Both the blockage detection device and the leak detection device are electrically connected to an encoder collector located inside the cavity. The electrical signal of the encoder collector is led out through a connection socket located on the connector head.

[0006] In the above scheme, the plug is provided with a through hole for installing a blockage detection device.

[0007] The above solution also includes a sealed and waterproof mounting base, which is an arc shape that matches the arc surface of the plug. A sealing groove is provided on the outer arc surface of the sealed and waterproof mounting base. The leakage detection device enters the sealed and waterproof mounting base from the inner arc surface and is introduced into the sealing groove. The code collector is set in the sealing groove and electrically connected to the leakage detection device. The sealing groove is sealed with resin waterproof seal.

[0008] In the above solution, the sealed and waterproof mounting base fits tightly with the plug and is bonded with waterproof adhesive.

[0009] The plug is provided with two groups of sealing rings and water stop strips, and the sealing and waterproof mounting seat is located between the two groups of water stop strips.

[0010] The sealing and waterproof mounting seat is provided with leakage detection devices at both ends, the leakage detection devices and the blockage detection devices are internally provided with floating balls, the leakage detection devices and the blockage detection devices are internally provided with flexible diaphragms, the flexible diaphragms are provided with trigger switches, and the trigger switches are electrically connected with the code collector.

[0011] The leakage detection devices are slidably connected with sliding frames, the sliding frames are provided with flexible diaphragms, the flexible diaphragms are provided with the trigger switches, the trigger switches are arranged in the sliding frames, the leakage detection devices are threadedly connected with threaded rods, and the threaded rods are rotatably connected with the upper walls of the leakage detection devices.

[0012] The sockets and the small pipes are provided with signal sockets and power sockets, the plug is provided with a power line, the power line is provided with plastic steel on the outside, and the power line is electrically connected with the power sockets and the code collector.

[0013] Compared with the prior art, the present application has the following advantages:

[0014] 1. The present application sets floating balls and flexible diaphragms in the blockage detection devices and the leakage detection devices, and installs trigger switches on the flexible diaphragms, so that when blockage or leakage occurs in the pipeline, the water pressure changes, the floating balls rise to press the flexible diaphragms to make the trigger switches work, thereby solving the technical problems that the existing detection sensors are easily eroded by acid and alkali substances, microorganisms adhere and electrochemical reactions cause data distortion and service life shortening due to direct contact with corrosive water.

[0015] 2. This invention solves the problems of existing technologies where limited pipe wall thickness leads to small direct sealing contact area and susceptibility to soil stress or thermal expansion and contraction, by setting a sealed and waterproof mounting base that matches the arc surface of the plug, and creating a sealing groove on the outer arc surface of the mounting base to accommodate the leakage detection device and the coding collector, and then filling the sealing groove with resin to achieve overall waterproofing. Through this technology, the sealed and waterproof mounting base provides a larger structural support surface and a uniform sealing pressure distribution; the resin filling further fills the tiny gaps and forms a continuous waterproof barrier, combined with the tight fit between the waterproof adhesive and the plug, constructing a multi-layered protection mechanism. This effectively prevents water vapor or corrosive media from penetrating from the interface into the cavity, thereby enhancing the connection stability of the leakage detection device, improving overall sealing reliability, and adapting to complex underground environmental changes.

[0016] 3. This invention solves the technical problem of existing detectors failing to dynamically adapt to minute leaks or high-sensitivity detection requirements based on actual operating conditions, resulting in false alarms or missed alarms, by using a threaded rod connected to the leak detection device and rotating it to adjust the height between the trigger switch and the flexible diaphragm. Through this technique, users can precisely control the trigger point position by rotating the threaded rod: lowering the height makes the system more sensitive to slight water level changes (such as minor leaks), while raising the height enhances anti-interference capabilities (avoiding triggering by non-target water flows). This mechanical adjustment requires no additional electronic components, resulting in a simple and reliable structure. This effectively matches the leak characteristics of different pipeline environments, thereby improving the adjustability of detection sensitivity, optimizing signal response accuracy, and expanding the applicability of the equipment.

[0027] Please see Figures 1-7 A non-contact plug-in connector for detecting blockages and leaks includes a buried pipe 1. A plug-in structure 2 is provided on one side of the buried pipe 1. The plug-in structure 2 includes a head 201 and a plug 202. An encoder 7 (via a sealed waterproof mounting base 6) is installed on the plug 202. The encoder 7 collects blockage information. The head 201 is fitted onto the buried pipe 1, and the plug 202 is inserted into the head 201, forming a sealed cavity. The encoder 7 is installed in the sealing groove of the sealed waterproof mounting base 6 and, after being sealed with resin, is installed within the cavity. The plug 202 inside the body is equipped with two sets of sealing rings 4 and water-stop strips 5. The encoder 7 is located between the two sets of water-stop strips 5. Because the encoder 7 is located inside the cavity (and its surface is sealed with epoxy resin), and is equipped with sealing rings 4 and water-stop strips 5 on both sides, the encoder 7 does not come into direct contact with the water inside the pipe, thus ensuring its normal operation and improving its service life. It is worth noting that the resin seal does not affect the introduction or exit of the various power lines and data lines of the encoder 7.

[0028] like Figure 2 , 4 As shown in Figure 6, it also includes a sealed waterproof mounting base 6, which is an arc shape that matches the arc surface of the plug 202. A sealing groove 203 is provided on the outer arc surface of the sealed waterproof mounting base 6. The leakage detection device 204 enters the sealed waterproof mounting base 6 from the inner arc surface and is introduced into the sealing groove 203. The code collector is set in the sealing groove 203 and is electrically connected to the leakage detection device 204. The sealing groove 203 is waterproofed and sealed by filling it with resin.

[0029] Both the leakage detection device 204 and the blockage detection device 205 have a floating ball 206 installed inside. Both the blockage detection device 205 and the leakage detection device 204 have a flexible diaphragm 207 installed inside. A trigger switch 209 is installed on the flexible diaphragm 207. The trigger switch 209 is electrically connected to the encoder 7. When the plug 202 is blocked, the water pressure inside the plug 202 will increase. When the water pressure increases, water will enter the blockage detection device 205 inside the plug 202. As the water pressure increases, the water level will rise continuously, which will drive the floating ball 206 inside the blockage detection device 205 to rise until the floating ball 206 contacts the trigger switch 209 through the flexible diaphragm 207. This will cause the encoder 7 to receive a blockage signal. The encoder 7 will then transmit the signal to an external terminal so that the staff can know the blockage situation inside the plug 202.

[0030] like Figure 5 As shown, the difference between the leakage detection device 204 and the blockage detection device 205 is that the leakage detection device 204 has a sliding frame 208 internally connected, a flexible diaphragm 207 is installed on the sliding frame 208, a trigger switch 209 is installed on the upper side of the flexible diaphragm 207, and the trigger switch 209 is installed inside the sliding frame 208. A threaded rod 210 is threadedly connected to the leakage detection device 204, and the threaded rod 210 is rotatably connected to the upper side wall of the leakage detection device 204. When leakage is detected, water inside the buried pipe 1 will enter the cavity between the bearing 201 and the plug 202 through the aged or damaged sealing ring 4 (or due to leakage in the plug 202). As the water level rises, it will enter the leakage detection device 204. As the water level rises, the floating... Ball 206 will contact trigger switch 209 through flexible diaphragm 207, causing encoder 7 to receive a leakage signal. Encoder 7 then transmits the signal to an external terminal, allowing staff to know the leakage situation inside plug 202. Specifically, the height between trigger switch 209 and flexible diaphragm 207 can be adjusted by rotating threaded rod 210 (mainly for sensitivity adjustment; the closer the distance between trigger switch 209 and flexible diaphragm 207, the smaller the required buoyancy. A small buoyancy will cause deformation of flexible diaphragm 207 to contact trigger switch 209), so that when floating ball 206 reaches the set water level, it can trigger switch 209. As one implementation, trigger switch 209 can be a pressure sensor or other sensor that can achieve the purpose of this invention.

[0031] like Figure 1 and Figure 2As shown, both the connector 201 and the plug 202 are equipped with signal sockets 302 and power sockets 3. A power cord 301 is wound around the plug 202 (or the power cord 301 can be placed within the tube wall of the plug 202). A plastic sleeve is fitted over the power cord 301, providing protection. The power cord 301 is electrically connected to the power socket 3 and the encoder 7. The power socket 3 on the plug 202 connects to the power cord 301 to supply power to the encoder 7. The signal socket on the connector 201...

[0032] 302 is connected to the signal line of the encoder 7, and the signal socket 302 is connected to the terminal to transmit signals, so that the terminal can know the real-time information of the water source inside the connector 201 and plug 202.

[0033] As a preferred implementation method:

[0034] The waterproof sealing mount 6 is an arc shape that matches the arc surface of the plug 202. A sealing groove 203 is provided on the outer arc surface of the waterproof sealing mount 6. The leakage detection device 204 enters the waterproof sealing mount 6 from the inner arc surface and is introduced into the sealing groove 203. The encoder is placed in the sealing groove 203 and is electrically connected to the leakage detection device 204. The sealing groove 203 is sealed with waterproof resin. The waterproof sealing mount 6 fits tightly with the plug 202 and is bonded with waterproof adhesive.

[0035] The technical problems with the implementation method are as follows: If the leakage testing device 204 is directly inserted into the mounting hole 2021 of the plugging device, with the working part of the leakage testing device 204 located inside the plug 201, and then the gap between the mounting hole 2021 and the leakage testing device 204 is filled with resin or other sealing materials, there may be a problem of sealing failure during long-term use. After all, the pipe wall thickness is very limited, which makes the sealing surface potentially unreliable. This invention seals the tail end of the leakage testing device 204 with resin using a waterproof sealing mounting base 6, which enhances the stability of the leakage testing device 204. Then, the waterproof sealing mounting base 6 and the plug 201 are sealed with waterproof adhesive, greatly improving the sealing effect. This effectively solves the problem of poor sealing effect due to the small contact area when directly sealing the leakage testing device 204 and the plug 201.

[0036] Working principle: When plug 202 becomes clogged, the water pressure inside plug 202 increases. This increased pressure draws water into the blockage detection device 205 inside plug 202. As the water pressure rises, the water level increases, causing the float ball 206 inside the blockage detection device 205 to rise until it contacts the trigger switch 209 through the flexible diaphragm 207. This triggers the encoder 7 to receive a blockage signal, which is then transmitted to an external terminal, informing the operator that plug 202 is clogged. 02. Internal blockage: When leakage is detected, water inside the buried pipe 1 will enter the cavity between the connector 201 and the plug 202 through the aged or damaged sealing ring 4. As the water level rises, it will enter the leakage detection device 204. As the water level rises, the floating ball 206 inside the leakage detection device 204 will contact the trigger switch 209 through the flexible diaphragm 207, causing the code collector 7 to receive the leakage signal. The code collector 7 then transmits the signal to the external terminal, allowing the staff to know about the leakage situation inside the plug 202.

[0037] This invention embeds the power cord inside the pipe wall, facilitating transportation and installation while also providing protection. This significantly reduces construction and wiring costs and ensures reliable power supply and transmission. The signal acquisition unit uses a flexible diaphragm to prevent contact between electronic components and the medium (water), avoiding accidents, solving the problem of cation accumulation, ensuring long-term reliable system operation, and providing strong support for the monitoring of underground pipe networks.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
