Description

Technical Field

[0001] This utility model belongs to the field of anti-electric shock wall technology, and in particular relates to an anti-electric shock wall water inlet pipe with detection function. Background Technology

[0002] Anti-electric shock wall technology is one of the core technologies for the safety protection of electric water heaters. It effectively reduces the current intensity in case of leakage by increasing the resistance of the water flow path, thus ensuring user safety. Traditional anti-electric shock wall structures mostly consist of multiple layers of insulating sleeves and sealing components. Existing split-type anti-electric shock wall structures use bolts to fix the upper and lower sleeves and use rubber gaskets to achieve a seal.

[0003] However, this type of structure has the following drawbacks: First, the bolted connection method is cumbersome to install and disassemble, requires special tools for maintenance, and has low maintenance efficiency; second, it lacks real-time monitoring of the electrified state of the water flow in the inlet pipe, relying solely on physical barriers, which cannot trigger early warnings in the early stages of leakage, posing a safety hazard; third, after long-term use, scale easily accumulates in the pipes, increasing water flow resistance and affecting the performance of the anti-electric shock wall. In addition, although some existing anti-electric shock walls have added leakage detection modules, their detection electrodes are mostly placed externally on the pipe surface, making them susceptible to interference from environmental humidity and resulting in a high false alarm rate. Furthermore, the electrodes lack protective design, and the adhesion of scale or impurities can lead to a decrease in detection sensitivity.

[0004] To address this issue, we provide an anti-electric shock inlet pipe with detection capabilities to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-electric shock wall water inlet pipe with detection function. Through the cooperation of quick-clamping mechanism and detection and protection mechanism, the problems of high risk of sealing failure and low maintenance efficiency of existing anti-electric shock wall water inlet pipes are solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an anti-electric shock wall water inlet pipe with detection function, comprising an anti-electric shock wall body, with a water inlet pipe body disposed at the bottom of the anti-electric shock wall body. The anti-electric shock wall body includes an upper anti-electric shock sleeve, a gasket, and a lower anti-electric shock sleeve. A quick-clamping mechanism is provided on the surface of the upper anti-electric shock sleeve, the quick-clamping mechanism including a mounting ring fixedly connected to the surface of the upper anti-electric shock sleeve, a driving ring disposed inside the mounting ring, a driving wheel fixedly connected to one side of the driving ring, a driving block disposed in the inner cavity of the mounting ring, and a clamping block fixedly connected to one side of the driving block. A detection and protection mechanism is provided in the inner cavity of the water inlet pipe body, the detection and protection mechanism including a filter screen fixedly connected to the inner cavity of the water inlet pipe body and an alarm light disposed in the inner cavity of the water inlet pipe body.

[0008] The present invention is further configured such that a drive rod is fixedly connected to the top of the drive ring, and the top of the drive rod is designed with rounded corners. The rounded corners of the drive rod can reduce the coefficient of friction with the bottom of the threaded sleeve and avoid stress concentration caused by sharp corners.

[0009] The present invention is further configured such that a threaded sleeve is threadedly connected to the surface of the upper anti-electric sleeve, the bottom of the threaded sleeve is in contact with the top of the drive rod, and the threaded sleeve linkage mechanism, the threaded sleeve with fine thread design can generate a corresponding axial displacement when it rotates a certain angle, and the drive rod is pushed by the end face pressure to realize the precise fine adjustment of the drive ring, so as to ensure that the clamping force is controllable.

[0010] The present invention is further configured such that a sealing ring is fixedly connected to the top of the lower anti-electric sleeve, a sealing groove adapted to the sealing ring is opened at the bottom of the upper anti-electric sleeve, and a slot adapted to the locking block is opened on the outer side of the sealing ring. The sealing ring is made of rubber and forms an interference fit with the sealing groove. With the radial locking force of the locking block, the pressure that the sealing interface can withstand is increased. The guide hole of the slide rod and the drive block are fitted with a clearance to restrict the drive block to only make radial linear movement, so as to ensure that the eight sets of locking blocks move synchronously.

[0011] The present invention is further configured such that a guide hole is provided on the surface of the driving block, and a slide rod is slidably connected to the inner cavity of the guide hole. The two ends of the slide rod are fixedly connected to the inner cavity of the mounting ring. When the spring is released from the locking position, it can provide an effective reset stroke to ensure that the locking block is completely disengaged from the slot.

[0012] The present invention is further configured such that a spring is sleeved on the surface of the slide rod, one end of the spring is fixedly connected to one side of the drive block, and the other end of the spring is fixedly connected to the inner cavity of the mounting ring.

[0013] The present invention is further configured such that the alarm light is a waterproof diode, the alarm light is located on one side of the filter screen, and the electrodes of the alarm light form a potential difference monitoring circuit. When the water resistance value is lower than the set value, an alarm is triggered. The filter screen filters the water flow to prevent impurities from adhering to the electrode rod of the alarm light and affecting the detection accuracy. At the same time, it prevents scale from clogging the anti-electric wall body and improves the service life of the anti-electric wall body.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model uses a rotating threaded pipe sleeve to drive the locking block to extend and retract radially, achieving one-handed locking of the upper and lower anti-electric sleeves. Combined with the double sealing structure of the sealing ring and sealing groove, it significantly shortens the disassembly and assembly time and improves the sealing reliability. It is especially suitable for emergency maintenance scenarios. A waterproof alarm light is integrated into the inner cavity of the water inlet pipe. Its electrodes are in direct contact with the water flow. It judges the leakage status in real time by detecting changes in water resistance. When leakage occurs, it triggers a visible light alarm, achieving millisecond-level response and significantly improving user safety.

[0016] 2. The filter screen of this utility model pre-filters the water flow, effectively intercepting impurities and scale, avoiding electrode contamination and pipe blockage, extending the service life of the anti-electric shock wall and detection module, reducing maintenance frequency. The anti-electric shock wall and detection mechanism adopt a split design, allowing for independent replacement of faulty parts, reducing maintenance costs. At the same time, the spring reset mechanism ensures smooth engagement and avoids mechanical jamming.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figures 1-5This utility model is an anti-electric shock wall water inlet pipe with detection function, including an anti-electric shock wall body 1, and a water inlet pipe body 2 at the bottom of the anti-electric shock wall body 1. The anti-electric shock wall body 1 includes an upper anti-electric shock sleeve 101, a gasket 102, and a lower anti-electric shock sleeve 103. The surface of the upper anti-electric shock sleeve 101 is provided with a quick-clamping mechanism, which includes an installation ring 3 fixedly connected to the surface of the upper anti-electric shock sleeve 101, a drive ring 4 disposed inside the installation ring 3, a drive wheel 5 fixedly connected to one side of the drive ring 4, a drive block 6 disposed in the inner cavity of the installation ring 3, and a clamping block 7 fixedly connected to one side of the drive block 6. The inner cavity of the water inlet pipe body 2 is provided with a detection and protection mechanism, which includes a filter screen 8 fixedly connected to the inner cavity of the water inlet pipe body 2 and an alarm light 9 disposed in the inner cavity of the water inlet pipe body 2.

[0028] Further details: The upper anti-electric sleeve 101 and the lower anti-electric sleeve 103 are axially connected through a quick-clamping mechanism. The mounting ring 3 is fixed to the outer wall of the upper anti-electric sleeve 101 in a ring-shaped structure and arranged circumferentially. The drive ring 4 and the mounting ring 3 adopt a concentric sleeve design. Eight sets of drive wheels 5 are evenly distributed on the inner circumference of the drive ring 4. Each set of drive wheels 5 drives a drive block 6. The clamping block 7 forms a multi-point clamping connection with the annular groove 14 opened on the top of the lower anti-electric sleeve 103. The filter screen 8 is made of stainless steel. The electrode contacts of the alarm light 9 are arranged parallel to each other at a safe distance upstream of the filter screen 8.

[0029] Example 2

[0030] Please see Figures 1-5 Based on embodiment 1, a drive rod 10 is fixedly connected to the top of the drive ring 4. The top of the drive rod 10 has a rounded corner design. A threaded tube sleeve 11 is threadedly connected to the surface of the upper anti-electric sleeve 101. The bottom of the threaded tube sleeve 11 contacts the top of the drive rod 10. A sealing ring 12 is fixedly connected to the top of the lower anti-electric sleeve 103. A sealing groove 13 adapted to the sealing ring 12 is opened at the bottom of the upper anti-electric sleeve 101. A slot 14 adapted to the locking block 7 is opened on the outer side of the sealing ring 12. A guide hole is opened on the surface of the drive block 6. A slide rod 15 is slidably connected to the inner cavity of the guide hole. Both ends of the slide rod 15 are fixedly connected to the inner cavity of the mounting ring 3. A spring 16 is sleeved on the surface of the slide rod 15. One end of the spring 16 is fixedly connected to one side of the drive block 6. The other end of the spring 16 is fixedly connected to the inner cavity of the mounting ring 3. The alarm light 9 is a waterproof diode and is located on one side of the filter screen 8.

[0031] Further details: The rounded corners of the drive rod 10 reduce the friction coefficient with the bottom of the threaded sleeve 11, avoiding stress concentration caused by sharp angles. The threaded sleeve 11 linkage mechanism, with its fine-thread design, generates corresponding axial displacement when rotated a certain angle. The end face pressure pushes the drive rod 10 to achieve precise micro-adjustment of the drive ring 4, ensuring controllable locking force. The sealing ring 12 is made of rubber and forms an interference fit with the sealing groove 13. Combined with the radial locking force of the locking block 7, it increases the pressure resistance of the sealing interface. The slide rod 15 has a clearance fit with the guide hole of the drive block 6, limiting the drive block 6 to only perform radial linear movement, ensuring synchronous movement of the eight sets of locking blocks 7. The spring 16 provides an effective reset stroke when the locking is released, ensuring that the locking block 7 completely disengages from the slot 14. The electrodes of the alarm light 9 form a potential difference monitoring circuit. When the water resistance value is lower than the set value, an alarm is triggered. The filter screen 8 filters the water flow, preventing impurities from adhering to the electrode rod of the alarm light 9 and affecting the detection accuracy. It also prevents scale from clogging the anti-electric wall body 1, improving the service life of the anti-electric wall body 1.

[0032] The working principle of this utility model is as follows: When assembling the anti-electric wall body 1, the operator engages the upper anti-electric sleeve 101 with the lower anti-electric sleeve 103, and then rotates the threaded tube sleeve 11. The threaded tube sleeve 11 drives the drive rod 10 to press down, and the drive ring 4 pushes the drive wheel 5 to move downward. The drive wheel 5 drives the drive block 6 to extend radially over the resistance of the spring 16, and drives the locking block 7 to embed into the annular locking groove 14 of the lower anti-electric sleeve 103. At this time, the sealing ring 12 and the sealing groove 13 form a double seal. The operation is simple and the sealing performance is high.

[0033] When water flows through the inlet pipe, if a leakage occurs, charged ions form a potential difference at the electrode rod of the alarm light 9, triggering the PN junction of the alarm light 9 to conduct and emitting a visible light alarm. The filter screen 8 filters the water flow to prevent impurities from adhering to the electrode rod of the alarm light 9 and affecting the detection accuracy. At the same time, it prevents scale from clogging the anti-electric wall body 1, thus improving the service life of the anti-electric wall body 1. When disassembling, the threaded sleeve 11 is rotated in the reverse direction, and the spring 16 pushes the drive block 6 to reset. The locking block 7 disengages from the locking slot 14 to achieve quick separation. Through the modular quick-disassembly structure and real-time water and electricity interlock monitoring, maintenance efficiency is improved, the response time to electrical faults is shortened, and the safety and maintenance convenience of the water heater system are significantly improved.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
