Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline leakage noise recorders, and particularly relates to a water supply pipeline leakage noise recorder. Background Art

[0002] During the maintenance of the water pipe network arranged by the water supply company, one of the maintenance items is to monitor or find the leakage points in the water pipe network in order to repair them in time and avoid waste of water resources.

[0003] Installing a noise recorder for the water pipe network on the pipe fittings to listen to the leakage sound and upload it for analysis is an effective way to monitor or find the leakage points. The noise recorder can be arranged in the water pipe network for a long term, short term or temporarily, continuously monitor the leakage situation, and send the monitored noise to the data processing computer, which judges whether there is a leakage by analyzing the noise data.

The noise recorder protective case includes a main case, a lid and a chassis. Some installation positions can be set on the lid and the chassis to fix components such as the circuit board and battery of the noise recorder. Specifically, an antenna hole and a connector installation hole are provided on the lid, and support columns for installing the circuit board are provided on the bottom surface of the lid.

However, since there is no connection structure between its electronic components and the main case, the fixation of its electronic components is not firm enough, so that the internal electronic components will be loosened and damaged when the device is collided.

[0007] 2. In the above patent, no installation structure is provided inside the main case, so that the electronic components in the device cannot be stacked and installed in sequence, resulting in low space utilization rate inside the device, and further resulting in a small application range of the above device. Summary of the Invention

[0008] The present invention provides a water supply pipeline leakage noise recorder, aiming to solve the problem that in the above patent mentioned in the background art, there is no connection structure between its electronic components and the main case, resulting in insufficient firm fixation of its electronic components, so that the internal electronic components will be loosened and damaged when the device is collided.

Both sides of the third mounting plate respectively match with the two third clamping members;

[0016] When it is necessary to fix the first mounting plate, the second mounting plate and the third mounting plate, first, the first mounting plate is sequentially clamped with one of the first clamping members, the second mounting plate is clamped with one of the second clamping members, and the third mounting plate is clamped with one of the third clamping members. Then, the left half-shell and the right half-shell are assembled. At this time, the two first clamping members, the two second clamping members and the two third clamping members are close to each other. As a result, both sides of the first mounting plate will be clamped by the two first clamping members, both sides of the second mounting plate will be clamped by the two second clamping members, and both sides of the third mounting plate will be clamped by the two third clamping members. In this way, it is convenient and quick to fix the first mounting plate, the second mounting plate and the third mounting plate, and the first mounting plate, the second mounting plate and the third mounting plate are convenient to disassemble, which is convenient for installing the components inside the device.

The number of the mounting holes is set to two. Fixing bolts are threadedly connected inside both of the two mounting holes. Plug rods are fixedly connected to the ends of the two fixing bolts. Chamfers are provided at the ends of the plug rods. The number of the clamping frames is set to two, and the lower ends of the two clamping frames are fixedly connected to the lower sealing cover;

Both of the two connecting shafts are arranged between the two limiting members. The two ends of the two connecting shafts are respectively fixedly connected to the two limiting members. Clamping members are hingedly arranged on the outer peripheries of the two connecting shafts. Both of the two clamping members are L-shaped, and bumps are fixedly connected to the ends of the two clamping members;

[0021] After the left half shell and the right half shell are joined together, the two first abutting plates will respectively abut against the two second abutting plates. Then, the lower sealing cover is sleeved on the bottom of the mounting shell. During this process, the two clamping frames on the top of the lower sealing cover will respectively be sleeved on the outside of two groups of adjacent first abutting plates and second abutting plates. At this time, the two fixing bolts are respectively threadedly fixed to the two mounting holes on the surface of the lower sealing cover. At the same time, the insertion rods at the ends of the two fixing bolts will respectively be inserted into the clamping frames through the insertion holes on the surfaces of the two clamping frames;

[0022] When the insertion rod is inserted into the interior of the clamping frame, the insertion rod will squeeze the bumps at one end of two adjacent clamping members. At this time, the two clamping members will respectively rotate around the joint point as the axis. At the same time, the two clamping members will respectively squeeze the first abutting plate and the second abutting plate, so that the first abutting plate and the second abutting plate are closely attached. Therefore, through the above structure, the two groups of mutually attached first abutting plates and second abutting plates can be closely attached, so as to complete the connection and fixation between the left half shell and the right half shell. Moreover, the first abutting plate and the second abutting plate will always be stressed and attached, so as to improve the sealing performance between the left half shell and the right half shell.

The top of the second limiting ring is detachably connected to the upper sealing cover through a plurality of bolts;

At this time, the two first abutting rods connected to the left half shell and the two second abutting rods connected to the right half shell will approach each other. At this time, the first limiting ring is sleeved on the first abutting rod and the second abutting rod that are close to each other at the bottom. At this time, the four first positioning grooves at the bottom of the first limiting ring will be respectively engaged with the two first connecting rods and the two second connecting rods. Then, the lower sealing cover is sleeved on the bottom of the mounting shell, and then the lower sealing cover is connected and fixed to the first limiting ring through bolts, so that the connection and fixation between the lower sealing cover and the first limiting ring can be completed. Through the above method, the limiting fixation between the second limiting ring and the first abutting rod and the second abutting rod at the top can also be completed, and the connection and fixation between the second limiting ring and the upper sealing cover are completed through bolts;

[0027] In the above structure, the first limiting ring can limit the first abutting rod and the second abutting rod at the bottom respectively, and the second limiting ring can limit the first abutting rod and the second abutting rod at the top respectively, so as to improve the structural strength between the left half shell and the right half shell, and further prevent the left half shell and the right half shell from separating due to external impact.

[0030] By providing two sealing strips, the airtightness between the left half shell and the right half shell can be improved. By providing the first sealing ring, the airtightness between the lower sealing cover and the mounting shell can be improved. By providing the second sealing ring, the airtightness between the upper sealing cover and the mounting shell can be improved. Therefore, through the above structure, it can be avoided that external water vapor enters the device through the gaps on the surface of the device and corrodes the electronic components inside the device, which is beneficial to improving the service life of the device. Moreover, the magnet arranged at the bottom of the lower sealing cover can facilitate the adsorption of the device on the surface of the water pipe, thus facilitating the installation of the device.

[0072] The working principle and usage process of the present invention:

[0073] When it is necessary to fix the first mounting plate 15, the second mounting plate 17 and the third mounting plate 19, first, the first mounting plate 15 is sequentially clamped with one of the first clamping members 21, the second mounting plate 17 is clamped with one of the second clamping members 22, and the third mounting plate 19 is clamped with one of the third clamping members 23. Then, the left half shell 11 and the right half shell 12 are assembled. At this time, the two first clamping members 21, the two second clamping members 22 and the two third clamping members 23 are close to each other. Thus, both sides of the first mounting plate 15 will be clamped by the two first clamping members 21, both sides of the second mounting plate 17 will be clamped by the two second clamping members 22, and both sides of the third mounting plate 19 will be clamped by the two third clamping members 23. In this way, it is convenient and fast to fix the first mounting plate 15, the second mounting plate 17 and the third mounting plate 19;

[0074] After the left half shell 11 and the right half shell 12 are joined together, the sealing strips 41 at both ends of the right half shell 12 will be inserted into the sealing grooves 4 at both ends of the left half shell 11 respectively, and the two first abutting plates 311 will abut against the two second abutting plates 312 respectively. Then, the lower sealing cover 14 is sleeved on the bottom of the mounting shell 1. During this process, the two clamping frames 3132 at the top of the lower sealing cover 14 will be sleeved on the outside of two groups of adjacent first abutting plates 311 and second abutting plates 312 respectively. At this time, the two fixing bolts 3133 are respectively threadedly fixed to the two mounting holes 3131 on the surface of the lower sealing cover 14. At the same time, the insertion rods 3134 at the ends of the two fixing bolts 3133 will be inserted into the clamping frames 3132 respectively through the insertion holes 3137 on the surfaces of the two clamping frames 3132;

[0075] When the insertion rod 3134 is inserted into the interior of the clamping frame 3132, the insertion rod 3134 will squeeze the convex blocks 3139 at one end of two adjacent clamping members 3138. At this time, the two clamping members 3138 will rotate respectively around the joint point as the axis. At the same time, the two clamping members 3138 will respectively squeeze the first abutting plate 311 and the second abutting plate 312, so that the first abutting plate 311 and the second abutting plate 312 are closely attached. Therefore, through the above structure, the two groups of mutually attached first abutting plates 311 and second abutting plates 312 can be closely attached, so that the connection and fixation between the left half shell 11 and the right half shell 12 can be completed, and the first abutting plate 311 and the second abutting plate 312 will always be stressed and attached, so that the sealing performance between the left half shell 11 and the right half shell 12 can be improved;

[0076] When the lower sealing cover 14 needs to be fixed, first the left half shell 11 and the right half shell 12 are joined together. At this time, the two first abutting rods 321 connected to the left half shell 11 and the two second abutting rods 322 connected to the right half shell 12 will approach each other. At this time, the first limiting ring 323 is sleeved on the first abutting rods 321 and the second abutting rods 322 that are close to each other at the bottom. At this time, the four first positioning grooves 327 at the bottom of the first limiting ring 323 will be respectively engaged with the two first connecting rods 325 and the two second connecting rods 326. Then, the lower sealing cover 14 is sleeved on the bottom of the mounting shell 1, and then the lower sealing cover 14 is connected and fixed to the first limiting ring 323 through bolts, so that the connection and fixation between the lower sealing cover 14 and the first limiting ring 323 can be completed. Through the above method, the limiting fixation between the second limiting ring 324 and the first abutting rods 321 and the second abutting rods 322 at the top can also be completed, and the connection and fixation between the second limiting ring 324 and the upper sealing cover 13 are completed through bolts;
