[0032] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0033] refer to Figures 1-6 This embodiment provides a vibration sensor for monitoring leaks in underground hot water pipes, including: a data acquisition component 1, a data transmission component 2, and a signal line 3 connected between the data acquisition component 1 and the data transmission component 2;

[0034] The data acquisition component 1 is installed on the wall of the hot water pipe, and collects the vibration data of the hot water pipe through the built-in piezoelectric sensor 11 and transmits it to the data transmission component 2 through the signal line 3;

[0035] The data transmission component 2 supplies power to the data acquisition component 1 via the signal line 3 and establishes a data connection with the cloud server to send the vibration data collected by the data acquisition component 1. This enables the use of a vibration sensor for monitoring leaks in underground hot water pipes, allowing for real-time and accurate detection of leaks.

[0036] To achieve data acquisition, a piezoelectric sensor 11 needs to be installed inside the data acquisition component 1. Therefore, the data acquisition component 1 includes a housing 12, a base 13, a pressure block 14, the piezoelectric sensor 11, a positive electrode 15, and a negative electrode 16. The housing 12 and the base 13 are assembled to form a cavity housing the piezoelectric sensor 11, the positive electrode 15, the negative electrode 16, and the pressure block 14. The positive electrode 15 and the negative electrode 16 are electrically connected to the signal line 3 via wires passing through the pressure block 14. This achieves the electrical connection between the piezoelectric sensor 11 and the pressure block 14. When pipeline vibration is transmitted to the sensor, it squeezes the piezoelectric sensor 11, generating an electric charge, which is collected by the positive electrode 15 and the negative electrode 16 and transmitted to the circuit board of the data transmission component 2 for processing via the signal line.

[0037] In this embodiment, two piezoelectric sensors 11 are stacked together. The positive electrode 15 is disposed between the two piezoelectric sensors 11, and the negative electrode 16 is disposed on the upper surface of the upper piezoelectric sensor 11. The negative electrode of the lower piezoelectric sensor 11 is connected to the negative electrode of the upper piezoelectric sensor 11 through a metal material such as the base 13 and the outer shell 12. This structure enables the acquisition of pipeline vibration by two piezoelectric sensors 11.

[0038] To secure the piezoelectric sensor 11, it is clamped between the pressure block 14 and the base 13. Specifically, the pressure block 14 has a channel 141 through which a bolt 17 passes. The piezoelectric sensor 11, the positive electrode 15, and the negative electrode 16 have clearance openings corresponding to the channel 141. The base 13 has threaded holes corresponding to the clearance openings. Thus, the bolt 17 can pass through the channel 141, through the clearance opening, and into the threaded hole, ultimately securing the pressure block 14 and the base 13, thereby clamping the piezoelectric sensor 11 between them.

[0039] Furthermore, the connection strength between the pressure block 14 and the base 13 needs to be controlled to prevent the gap between the control plate and the base 13 from being too small, which would cause excessive pressure on the piezoelectric sensor 11 and damage it. A raised edge 142 extends radially inward from the inner wall of the channel 141. When the bolt 17 is connected to the threaded hole, the nut of the bolt 177 abuts against the raised edge 142. The raised edge 142 limits the depth of the bolt 17 into the threaded hole, thus preventing the aforementioned situation from occurring.

[0040] The base 13 has a recessed cavity on the side facing the pressure block 14 for placing the piezoelectric sensor 11, the positive electrode 15, and the negative electrode 16. A threaded hole is provided at the bottom of the cavity. This cavity design allows for the positioning of the piezoelectric sensor 11, the positive electrode 15, and the negative electrode 16, ensuring that their positions automatically align with the threaded hole without requiring excessive calibration.

[0041] In order to install the data acquisition component 1 on the wall of the hot water pipe, the base 13 is provided with a magnet for adsorbing the data acquisition component 1 onto the wall of the hot water pipe.

[0042] In order to enable the data transmission component 2 to supply power to the data acquisition component 1 via the signal line 3, the data transmission component 2 has a built-in battery 21 and a circuit board.

[0043] Finally, the data acquisition component 1 and the data transmission component 2 are stably connected via a signal line 3. Each end of the signal line 3 is provided with a sealing plug 31 for the data acquisition component 1 and the data transmission component 2, respectively. The sealing plug 31 has an insertion portion 311 for inserting the data acquisition component 1 and the data transmission component 2, and a connection portion 312 for inserting the signal line 3. The insertion portion 311 has a circumferentially arranged annular groove 3111. The data acquisition component 1 and the data transmission component 2 are respectively provided with flanges 18 and 22 that mate with the annular groove 3111. When the insertion portion 311 is inserted into the data acquisition component 1 and the data transmission component 2, the flanges 18 and 22 are placed within the annular groove 3111 and are respectively positioned and engaged with the inner walls on both sides of the annular groove 3111.

[0044] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
