Description

Technical Field

[0001] This utility model relates to the field of municipal pipeline facilities technology, specifically an NFC-based smart valve well. Background Technology

[0002] A valve well is a pit, similar to a small room, where valves and other equipment are installed in underground pipelines and conduits (such as water, oil, and natural gas pipelines). This is to facilitate the opening and closing of parts of the pipeline or to carry out maintenance work. It is a key component for regular inspection, cleaning, and unblocking of the pipeline, preventing blockages.

[0003] Traditional valve wells rely on manual periodic opening and inspection, which suffers from problems such as cumbersome operation, slow response, and easy damage to the seal. Although existing technologies have attempted to integrate electronic monitoring devices, they mostly adopt wired transmission or independent power supply solutions, which face drawbacks such as complex wiring, difficult battery replacement, and insufficient waterproofing. Utility Model Content

[0004] This utility model addresses the problems existing in the prior art by providing an NFC-based smart valve well. It includes:

[0005] A sealed well body consisting of a lower box and an upper raised top plate;

[0006] The valve well located inside the well body and the main pipeline running through it;

[0007] Support blocks are fixed to the bottom of the lower housing to support the main pipe;

[0008] An NFC card assembly is installed inside the valve well, adjacent to the support pad, and is used to monitor the internal status of the valve well via near-field communication.

[0009] Preferably, the NFC card assembly includes a lower mounting block, a hydraulic cylinder, a first limiting block, a second limiting block, and an NFC chip. The lower mounting block is fixedly disposed at the bottom of the inner side of the valve well. The first limiting block and the second limiting block are disposed above the lower mounting block. Hydraulic cylinders are disposed on the outer sides of both the first limiting block and the second limiting block. The NFC chip is embedded in the lower mounting block, and the first limiting block and the second limiting block limit and fix the inner NFC chip.

[0010] Preferably, both the first limiting block and the second limiting block are provided with pad clamps on their inner sides to improve the stability of the NFC chip.

[0011] Preferably, a drainage groove is provided at the connection position between the upper raised top plate and the lower box body, and reinforcing ribs are provided on the inner wall of the upper raised top plate.

[0012] Preferably, the valve well is further provided with a matching valve, which is installed on the main pipeline.

[0013] Preferably, the NFC chip is communicatively connected to the sensor module for real-time acquisition of valve opening / closing status, pipeline pressure, and leakage data.

[0014] Preferably, the support pad is made of a corrosion-resistant elastic material, and its surface has an arc-shaped groove that matches the main pipe.

[0015] Preferably, the matching valve is a butterfly valve or a ball valve.

[0016] Preferably, the drainage channels are distributed in a grid pattern, and the reinforcing ribs are in a cross-shaped structure.

[0017] Preferably, the NFC chip is a passive RFID tag with an operating frequency of 13.56MHz.

[0018] Compared with the prior art, this utility model provides an NFC-based smart valve well, which has the following advantages:

[0019] 1. The valve well is equipped with an NFC chip, which does not require an internal power supply. It can be activated and read data through an external device, thereby effectively improving the efficiency of staff in analyzing and extracting parameters inside the valve well;

[0020] 2. The upper part of the valve well is designed to prevent leakage. By setting a sealed well body combined with a grid drainage channel, it effectively prevents external water from seeping in and effectively improves the sealing performance of the valve well. Attached Figure Description

[0031] Example 1:

[0032] like Figure 1-3 As shown, this embodiment provides an NFC-based smart valve well, including:

[0033] Sealed well body: It is composed of a lower box body 1 and an upper raised top plate 2 connected by bolts. The connection is provided with a grid-shaped drainage channel 1001, and the inner wall of the top plate is prefabricated with cross-shaped reinforcing ribs 1002. The grid-shaped drainage channel 1001 can effectively improve the drainage capacity of the upper part of the valve well, thereby ensuring that its drainage performance is effectively improved in rainy weather. The reinforcing ribs 1002 provided on the inner wall of the top plate can improve the overall strength of the sealed well body and further improve the overall service life of the valve well.

[0034] Piping system: The main pipe 4 passes through the valve well 3, and its bottom is fixed by a support pad 5. The pad is made of nitrile rubber and has an arc-shaped groove on its surface that matches the curvature of the pipe.

[0035] NFC monitoring component: Installed at the bottom of valve well 3 near support pad 5, the internal components include a lower mounting block 101, a hydraulic cylinder 102, a first limiting block 103, a second limiting block 104, an NFC chip 105, and a gasket clamping plate 106. The lower mounting block 101 is fixed to the bottom of the well with anchor bolts. The NFC chip 105 is embedded in the slot of the lower mounting block 101 (operating frequency 13.56MHz). The first limiting block 103 and the second limiting block 104 are driven inward by the hydraulic cylinder 102, and the silicone gasket clamping plate 106 on their inner side presses against the edge of the chip, thereby fixing the NFC chip 105. This prevents the built-in NFC chip from becoming unstable due to external interference during daily use, reducing the frequency of subsequent maintenance.

[0036] During the use of this valve well, the assembly process is as follows: the worker fixes the support pad 5 to the bottom of the lower box 1, and places the main pipe 4 in the groove of the pad; then the NFC chip 105 is placed into the lower mounting block 101, and the hydraulic cylinder 102 is activated to push the limit block to clamp the chip; the upper raised top plate 2 is sealed and installed to ensure that the drainage channel 1001 is tilted towards the outside of the well.

[0037] Meanwhile, during the subsequent NFC reading phase, maintenance personnel hold the NFC reader / writer device close to the manhole cover (effective distance ≤ 10cm); the reader / writer device activates the passive NFC chip 105 to obtain the stored valve number, pipeline pressure data, and last maintenance record; the chip collects the valve opening and closing status in real time through the built-in sensor (when the opening degree is ≥ 90%, it is marked as fully open).

[0038] Example 2:

[0039] In some special cities, the intelligent valve well has been improved based on Example 1 as follows:

[0040] The improvements include optimizing the types of valves usable inside the smart valve well, replacing valve 7 with a ball valve, and adding NFC functionality. Chip 105 connects to a leakage sensor (not shown in the figure). When the humidity inside the well exceeds 85%, the chip stores alarm code "E01". Simultaneously, the internal limiting structure needs optimization, with anti-slip textures added to the surface of the gasket clamp 106, improving the chip's vibration resistance by 40%. Through these improvements, the ball valve inside the smart valve well has better sealing performance and NFC monitoring compatibility, effectively improving the accuracy of opening and closing status recognition. Furthermore, leakage alarm data is transmitted to the backend system via NFC, effectively reducing response lag time.
