Description

Technical Field

[0001] The present invention relates to the technical field of water meter communication line protection, in particular to a communication line protection structure of a wet-type photoelectric direct-reading water meter head. Background Art

[0002] Wet-type photoelectric direct-reading water meter is a metering device that combines photoelectric sensing technology and wet-type water meter structure. It is mainly used in automatic meter reading systems and realizes remote direct reading of water volume through photoelectric sensors.

[0003] As a key equipment in the automatic meter reading system, the wet-type photoelectric direct-reading water meter realizes remote direct reading of water volume by means of photoelectric sensing technology and is widely used in the water supply system. The communication line of the meter head is the core channel for data transmission, but its protection problem has always been the key issue affecting the stable operation of the water meter. At present, the communication line of the wet-type photoelectric direct-reading water meter head lacks a special and effective protection structure. The existing protection measures have poor adaptability to the fixation of the communication line and are difficult to meet the fixation requirements of communication lines of different specifications. After fixation, the communication line is prone to loosening due to environmental vibration, causing the communication line to loosen or even break when pulled by external force, affecting the normal data transmission. At the same time, the protective cover of the communication line is not fixed reliably and is prone to displacement. The protection effect is unstable and cannot effectively resist external mechanical damage, water vapor erosion and electromagnetic interference, which greatly shortens the service life of the communication line. Therefore, it is necessary to redesign the communication line protection structure of the wet-type photoelectric direct-reading water meter head to address the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-7 , the communication line protection structure of the wet photoelectric direct-reading water meter head includes a water meter body 1, a connecting pipe 2 communicating with the interior is fixedly installed on the outer wall of the water meter body 1, a sealing sleeve 3 is installed inside the connecting pipe 2 for sealing and sliding, two connecting frames 4 are fixedly installed on the outer wall of the water meter body 1, and the two connecting frames 4 are fixedly installed with connecting blocks 6 by screws 5. The outer walls of the two connecting blocks 6 are fixedly connected to the connecting frame 8 through a connecting mechanism, and a bidirectional screw 9 is rotatably installed inside the connecting frame 8. The outer wall of the bidirectional screw 9 is fixedly installed with an inner hexagonal nut 10. The outer wall of the bidirectional screw 9 is rotatably installed with two moving blocks 12 by thread. The connecting frame 8 is fixedly installed with a limited The positioning rod 11 and the limiting rod 11 slide through the two moving blocks 12. The bottom walls of the two moving blocks 12 are fixedly connected with a clamping plate 14 through a connecting mechanism. The inner walls of the two clamping plates 14 are fixedly installed with anti-slip pads 15. The inner walls of the two anti-slip pads 15 are provided with multiple V-shaped clamping openings. The outer wall of the two-way screw 9 is fixedly installed with a locking nut 16. The outer wall of the connecting frame 8 is fixedly installed with a support plate 17. The upper end surface of the support plate 17 is slidably installed with a prismatic rod 19 through a sliding mechanism. The outer wall of the prismatic rod 19 is fixedly installed with a shift block 20. The end of the prismatic rod 19 is fixedly installed with a fixed block 21. The upper end surface of the fixed block 21 is connected to the bottom wall of the support plate 17 through a pressing mechanism.

[0025] Furthermore, the sealing sleeve 3 can enhance the sealing between the connecting pipe 2 and the communication line, preventing water vapor or dust from entering the water meter body 1 through the gap and affecting the operation of the equipment; the hexagonal nut 10 facilitates the use of special tools to rotate the bidirectional screw 9, and the limit rod 11 can prevent the moving block 12 from rotating with the bidirectional screw 9, ensuring that it only moves stably in the horizontal direction. Multiple V-shaped clamping openings can adapt to communication lines of different diameters, thereby improving the adaptability of the clamping.

[0026] The connecting mechanism includes a connecting rod 7 fixedly mounted on the outer wall of the connecting block 6 , a guide opening cooperating with the connecting rod 7 is opened on the outer wall of the connecting frame 4 , and the end of the connecting rod 7 is fixedly connected to the outer wall of the connecting frame 8 .

[0027] Furthermore, the guide opening provides precise guidance for the movement of the connecting rod 7, so that the connecting frame 8 can move along a preset trajectory during installation or adjustment, thereby ensuring the assembly accuracy of the overall structure. At the same time, the fixed connection between the connecting rod 7, the connecting block 6 and the connecting frame 8 enhances the integrity of the structure, thereby avoiding looseness when clamping the communication line.

[0028] The connection mechanism includes a connection rod 13 fixedly mounted on the bottom wall of the moving block 12 , and an end of the connection rod 13 is fixedly connected to the outer wall of the clamping plate 14 .

[0029] Furthermore, the connecting rod 13 converts the horizontal movement of the moving block 12 into the synchronous movement of the clamping plate 14. Its length design ensures that the clamping plate 14 can be accurately aligned with the clamping position of the communication line, and the rigid material of the connecting rod 13 can withstand the force generated during clamping, preventing deformation due to force from affecting the clamping effect.

[0030] The sliding mechanism includes a support plate 17 , an upper end surface of which is fixedly mounted with a sliding sleeve 18 through a mounting opening, and a prismatic rod 19 slidably mounted inside the sliding sleeve 18 .

[0031] Furthermore, the sliding sleeve 18 provides a stable sliding track for the prismatic rod 19. The prismatic structure design can effectively prevent the prismatic rod 19 from rotating during the sliding process, ensuring the directionality and stability of the prismatic rod 19 when the shift block 20 drives the movement, and avoiding deviation in the fit between the fixed block 21 and the fixed opening due to rotation.

[0032] The pressing mechanism includes a pressing spring 22 mounted on the outer wall of the prismatic rod 19 , and both ends of the pressing spring 22 are elastically connected to the bottom wall of the support plate 17 and the upper end surface of the fixing block 21 respectively.

[0033] Furthermore, the elastic force of the downward pressure spring 22 always exerts downward pressure on the fixing block 21, ensuring that the fixing block 21 can be tightly stuck in the fixing opening of the protective cover 23 when there is no external force interference, thereby enhancing the installation stability of the protective cover 23 and preventing it from accidentally slipping during use.

[0034] A protective sleeve 23 is slidably installed on the outer wall of the connecting pipe 2. A movable opening that cooperates with the two connecting rods 13 is opened on the outer wall of the protective sleeve 23. A fixed opening that cooperates with the fixed block 21 is opened on the outer wall of the protective sleeve 23. A threading opening is opened at the end of the protective sleeve 23. A metal braided mesh sleeve 24 is fixedly installed on the inner wall of the threading opening. An insulating rubber layer 25 is fixedly installed inside the metal braided mesh sleeve 24, and a shielding layer 26 is fixedly installed on the inner wall of the insulating rubber layer 25.

[0035] Furthermore, the size design of the movable opening reserves space for the movement of the connecting rod 13 to prevent the protective cover 23 from obstructing the adjustment of the clamping plate 14 after installation. The metal braided mesh cover 24 can enhance the structural strength of the threading port to prevent the communication line from being pulled and causing damage to the threading port. The insulating rubber layer 25 plays an insulating protection role to avoid leakage between the communication line and the protective cover 23. The shielding layer 26 can effectively block external electromagnetic interference and ensure the stable transmission of communication signals.

[0036] When the present invention is used, the sealing sleeve 3 can be put on the outside of the communication line, and it is important to ensure that the sealing sleeve 3 completely covers the end portion of the communication line connected to the water meter body 1. Then, one end of the communication line covered with the sealing sleeve 3 is inserted into the interior of the connecting pipe 2, and the sealing sleeve 3 is pushed to slide inside the connecting pipe 2 until the outer wall of the sealing sleeve 3 is in complete and tight contact with the inner wall of the connecting pipe 2. At this time, the sealing sleeve 3 will be elastically deformed due to being squeezed, and will fit tightly between the inner wall of the connecting pipe 2 and the outer wall of the communication line, thereby forming the first effective sealing barrier, which can effectively prevent external water vapor, dust, etc. from entering the interior of the water meter body 1 through the gap between the connecting pipe 2 and the communication line, and protect the internal components of the water meter from erosion;

[0037] After completing the installation of the sealing sleeve 3, align the end of the communication line away from the water meter body 1 with the threading hole at the end of the protective sleeve 23, and slowly pass the communication line through the threading hole, so that the communication line passes through the metal braided mesh sleeve 24 on the inner wall of the threading hole, the insulating rubber layer 25 inside the metal braided mesh sleeve 24, and the shielding layer 26 on the inner wall of the insulating rubber layer 25 in turn. During the process, ensure that the communication line remains straight inside the protective sleeve 23 without twisting. Then, hold the middle part of the protective sleeve 23 with your hand, and slide it along the outer wall of the connecting pipe 2 toward the water meter body 1 until the end of the protective sleeve 23 is close to the connecting frame 4. In the process of sliding the protective sleeve 23, pay attention to the moving opening of the outer wall of the protective sleeve 23 to ensure that the connecting rod 13 can pass through the opening smoothly. The two cooperate with each other to avoid collision and interference between the protective sleeve 23 and the connecting rod 13 during movement, and ensure that the protective sleeve 23 can move smoothly to the specified position;

[0038] After that, take out the hexagonal wrench, align it with the hexagonal nut 10 and insert it, slowly turn the hexagonal wrench, the hexagonal nut 10 will drive the bidirectional screw 9 to start rotating inside the connecting frame 8. Since the thread directions at both ends of the bidirectional screw 9 are opposite, and the moving block 12 is passed through by the limit rod 11, it is restricted by the limit rod 11 and cannot rotate with the bidirectional screw 9. The two moving blocks 12 will move relatively close to the limit rod 11 along the length direction of the bidirectional screw 9. While moving, the moving block 12 will drive the clamping plate 14 to move synchronously through the connecting rod 13 at the bottom, so that the two clamping plates 14 gradually approach the communication line. When the inner wall of the clamping plate 14 is After the anti-slip pad 15 contacts the outer wall of the communication line, continue to turn the hexagonal wrench. At this time, the anti-slip pad 15 will gradually fit the communication line, and the multiple V-shaped clamping openings on it will automatically adapt according to the diameter of the communication line, tightly wrapping the communication line until you feel obvious resistance to the applied force, indicating that the communication line has been stably clamped. Then, use a wrench to tighten the locking nut 16 to make it close to the outer wall of the connecting frame 8 and make close contact, firmly fixing the bidirectional screw 9 to prevent it from rotating due to pipeline vibration, external collision, etc. during the subsequent use of the water meter, thereby ensuring that the clamping force of the clamping plate 14 on the communication line is always stable, preventing the communication line from loosening;

[0039] When the locking block 21 is lifted above the outer wall of the protective sleeve 23, the locking block 21 is released and the locking block 22 is released, so that the locking block 21 is locked and the locking block 22 is released.

[0040] If the communication line needs to be repaired or replaced, the operation steps are opposite to those during installation. First, use your fingers to push the dial block 20 upward to disengage the fixing block 21 from the fixed opening of the protective cover 23. Then, hold the protective cover 23 and slide it along the outer wall of the connecting pipe 2 in the direction away from the water meter body 1 until the protective cover 23 moves to a suitable position that does not hinder the operation of the communication line. Next, use a wrench to loosen the locking nut 16 to separate it from the outer wall of the connecting frame 8, and then use the hexagonal wrench to reversely rotate the hexagonal nut 10 to drive the two-way screw 9 to rotate in the opposite direction. The two moving blocks 12 will move away from each other along the two-way screw 9 and the limit rod 11. The clamping plate 14 is driven to separate synchronously through the connecting rod 13, so that the anti-slip pad 15 is out of contact with the communication line, and the clamping of the communication line is loosened. After that, the communication line can be repaired, replaced, etc. After the operation is completed, follow the above-mentioned installation steps to re-fix the communication line and install the protective cover 23.

[0041] When the connecting frame 8 needs to be disassembled, it is necessary to first follow the above-mentioned steps for inspecting or replacing the communication line, remove the protective cover 23 and loosen the clamping of the communication line, and ensure that there is no obstruction or restraint around the connecting frame 8. Then, use a screwdriver to unscrew the screws 5 inside the two connecting frames 4. At this time, the fixed relationship between the connecting block 6 and the connecting frame 4 is released, and the connecting block 6 can move freely inside the connecting frame 4. Since the connecting frame 8 is fixedly connected to the connecting block 6 by the connecting rod 7, you can directly grab the two ends of the connecting frame 8 with your hands and pull outward. The connecting frame 8 will drive the connecting block 6 and the connecting rod 7 to slide along the guide opening of the outer wall of the connecting frame 4 until the connecting block 6 is completely separated from the connecting frame 4. The connecting frame 8 is successfully removed. If the connecting frame 8 needs to be reinstalled later, just align the connecting block 6 with the entrance of the connecting frame 4 and insert it. After sliding it to the appropriate position, use a screwdriver to re-tighten the screws 5.

[0042] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
