Description

Technical Field

[0001] This application relates to the field of power generation, and in particular to a miniature vibration generator for a pipeline inspection device. Background Technology

[0002] In industrial production, pipeline systems play a crucial role, widely used in various factories to transport diverse fluid media. With the development of industrial automation and intelligence, accurate monitoring of pipeline operating status has become increasingly important. Accurately obtaining parameters such as flow rate and pressure in pipelines helps ensure the safety, stability, and efficiency of the production process.

[0003] Traditionally, many factories use monitoring devices to measure parameters such as flow rate and pressure in pipelines. These devices typically consist of wireless sensors powered by built-in batteries. In practice, when wireless sensors need to be deployed on pipelines in different locations, appropriate installation methods are chosen to secure them. Powered by the batteries, the wireless sensors can operate continuously, collecting and transmitting relevant pipeline parameters. Once installed, staff only need to periodically review the monitoring data to understand the pipeline's operational status.

[0004] However, the batteries in wireless sensors gradually deplete during use. When the batteries run out of power, staff need to recharge them. This process not only increases labor costs but is also cumbersome, consuming a significant amount of staff's time and energy, and causing considerable inconvenience to the factory's daily operations. Utility Model Content

[0005] To facilitate charging of the testing device, this application provides a miniature vibration generator for a pipeline testing device.

[0006] This application provides a miniature vibration generator for a pipeline inspection device, which adopts the following technical solution: A miniature vibration generator for a pipeline inspection device includes a housing for connection to a pipeline. Inside the housing, two magnetic blocks are mounted opposite each other, and a winding assembly is disposed between the two magnetic blocks. The winding assembly is equipped with a movable component and connected to two wires. The housing has through holes for the wires to pass through, and the wires are used to connect to the pipeline inspection device.

[0007] By adopting the above technical solution, a micro vibration generator can be installed on a pipeline. The vibration of the pipeline causes the winding assembly to move between the magnetic blocks, generating electrical energy and powering the pipeline inspection device through wires. This reduces the inconvenience of having to charge the battery-powered inspection device.

[0008] Optionally, an amplifying rod is fixedly installed on the top side of the housing. The amplifying rod is flexible, and a connecting plate is fixedly installed at the top end of the amplifying rod. The connecting plate is provided with cable ties, which are used to bind the connecting plate to the pipe.

[0009] By adopting the above technical solution, the amplifier rod is fixed to the pipeline by connecting plate and cable tie. The flexible amplifier rod can better vibrate with the pipeline, increase the vibration transmission effect, and thus improve the power generation efficiency of the generator.

[0010] Optionally, a connecting rope is fixedly installed between the connecting plate and the housing, and the length of the connecting rope is greater than the distance between the connecting plate and the housing.

[0011] By adopting the above technical solution, the amplification rod can amplify the vibration amplitude when the pipeline vibrates. The connecting plate at the top of the flexible amplification rod can be tied to the pipeline with cable ties, and the connecting rope can prevent the amplification rod from breaking due to excessive vibration amplitude, thus ensuring the normal operation of the generator.

[0012] Optionally, the amplifying rod has a placement groove on its body, the connecting rope is located inside the placement groove, and a cover plate is provided at the opening of the placement groove to seal the opening of the placement groove.

[0013] By adopting the above technical solution, the connecting rope is placed in the slot of the amplifier rod body and the slot is sealed with a cover plate, which can prevent the connecting rope from being exposed and damaged, and ensure the service life and connection stability of the connecting rope.

[0014] Optionally, the winding assembly is elongated, and there are two movable components located at both ends of the winding assembly. Each movable component includes a support plate, a spring, a first limiting block, and a guide rod. The support plate is fixedly installed inside the housing, one end of the guide rod is fixedly connected to the winding assembly, and the support plate has a guide hole for the guide rod to pass through. The spring is sleeved on the guide rod, and the first limiting block is fixedly installed at the end of the guide rod away from the winding assembly. The spring is fixedly connected to the first limiting block and abuts against the support plate.

[0015] By adopting the above technical solution, the guide rod passes through the guide hole of the support plate, and the spring is sleeved on the guide rod and connected to the first limiting block and the support plate, which can guide the vibration of the winding group and ensure that the winding group vibrates stably to generate electricity.

[0016] Optionally, the diameter of the through hole is larger than the diameter of the wire, and a shielding cloth is fixedly installed on the periphery of the wire, with the periphery of the shielding cloth being fixedly connected to the inner wall of the through hole.

[0017] By adopting the above technical solution, the vibration of the winding group will cause the conductor to move. Setting up a shielding cloth can separate the conductor from the inner wall of the through hole, reduce the probability of the conductor being damaged by friction, and extend the service life of the conductor.

[0018] Optionally, the wire is fixedly fitted with a first mounting ring, and the wire is slidably fitted with a plurality of second mounting rings. The second mounting rings are located on the side of the first mounting ring away from the housing. Both the first and second mounting rings are fixedly fitted with a fixing member. The first and second mounting rings are installed on the pipe through the fixing member, which is a suction cup.

[0019] By adopting the above technical solution, the miniature vibration generator can be installed on the pipeline using the fixing parts on the first and second mounting rings, thereby fixing the conductor and preventing conductor swaying from affecting the connection stability between the generator and the pipeline detection device. Optionally, the movable component includes a support tube, a bearing, an insulating ring, and a second limiting block. The support tube is fixedly installed inside the housing and passes through the magnetic block. The bearing is fixedly sleeved on the support tube, and the insulating ring is fixedly installed on the outer ring of the bearing. The winding assembly is annular with both sides recessed inward and fixedly connected to the insulating ring. The wire is routed along the inside of the support tube. The second limiting block is fixedly installed between the two magnetic blocks and is used to limit the rotation angle of the winding assembly.

[0020] By adopting the above technical solution, when vibrating, the winding assembly rotates and cuts the magnetic field lines, thereby powering the pipeline detection device and reducing the inconvenience of manually charging the wireless sensor battery when it runs out of power.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. A miniature vibration generator uses the vibration of the pipeline to make the winding assembly move between the magnetic blocks to generate electricity, which powers the pipeline detection device and reduces the trouble of manually charging the wireless sensor battery when it runs out of power; 2. Structures such as amplifying rods and connecting plates can enhance vibration, improve the generator's power generation efficiency, and ensure that the pipeline inspection device has a continuous supply of sufficient power to operate.

[0024] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0025] Example 1.

[0026] This application discloses a miniature vibration generator for a pipeline inspection device.

[0027] Reference Figure 1 , Figure 2 A miniature vibration generator for a pipeline inspection device includes a housing 1. An amplifying rod 2 is fixedly mounted on the top side of the housing 1, and a connecting plate 3 is fixedly mounted on the top end of the amplifying rod 2. The connecting plate 3 is equipped with cable ties 4, and the connecting plate 3 is secured to the pipeline via the cable ties 4. When liquid or gas flows inside the pipeline, the pipeline vibrates. This vibration is amplified by the amplifying rod 2 and transmitted to the housing 1, thereby increasing the vibration amplitude of the housing 1 and improving the power generation efficiency. The amplifying rod 2 is made of a flexible material such as rubber or plastic.

[0028] Reference Figure 2 , Figure 3 Magnetic blocks 5 are fixedly installed on the two opposite inner sidewalls of the housing 1, and a winding assembly 6 is arranged between the two magnetic blocks 5. The winding assembly 6 is elongated. The winding assembly 6 moves between the magnetic blocks 5, cutting magnetic lines of force to generate current, which powers the pipeline detection device, reducing the inconvenience of manual charging required by traditional battery power.

[0029] Reference Figure 3Both ends of the winding assembly 6 are equipped with movable components 7. The movable components 7 enable the winding assembly 6 to generate relative movement when the pipeline vibrates. The movable components 7 include a support plate 71, a spring 72, a first limiting block 73, and a guide rod 74. The support plate 71 is fixedly installed inside the housing 1, and one end of the guide rod 74 is fixedly connected to the winding assembly 6. The support plate 71 has a guide hole 8, and the guide rod 74 can slide freely within the guide hole 8, serving a guiding function.

[0030] Reference Figure 3 A spring 72 is sleeved on a guide rod 74, and a first limiting block 73 is fixedly installed on the end of the guide rod 74 away from the winding assembly 6. One end of the spring 72 is fixedly connected to the first limiting block 73, and the other end abuts against the support plate 71. When the pipe vibrates, the winding assembly 6 will reciprocate between the magnetic blocks 5 under the action of the spring 72, thereby cutting the magnetic lines of force to generate current. This design of the movable component 7 not only ensures the stable movement of the winding assembly 6, but also reduces the risk of collision damage between the winding assembly 6 and the magnetic blocks 5.

[0031] Reference Figure 1 , Figure 3 The winding assembly 6 is connected to two conductors 9, which are generally made of copper and have good conductivity. The housing 1 has through holes 17 for the conductors 9 to pass through.

[0032] A charging circuit is pre-installed in the detection device, and wire 9 is connected to the charging circuit of the detection device to facilitate charging. In another embodiment, the charging circuit can be located in the housing 1. The charging circuit can be configured similarly to a solar charging circuit.

[0033] The implementation principle of the micro vibration generator for a pipeline inspection device in this application embodiment is as follows: The vibration of the pipeline itself causes the winding assembly 6 to move between the magnetic blocks 5, cutting magnetic lines of force to generate current, which powers the pipeline inspection device. Compared to traditional battery power supply, this reduces the inconvenience of manual charging and lowers labor costs. Furthermore, the power generation efficiency can be enhanced by setting an amplification rod 2.

[0034] Example 2.

[0035] This application discloses a miniature vibration generator for a pipeline inspection device.

[0036] Reference Figure 4 , Figure 5 , Figure 6The difference between the micro vibration generator used in this embodiment of the pipeline inspection device and Embodiment 1 is that a connecting rope 11 is fixedly installed between the connecting plate 3 and the housing 1. The connecting rope 11 is made of nylon and its length is greater than the distance between the connecting plate 3 and the housing 1. In the event of an accidental breakage of the amplitude rod, the connecting rope 11 prevents the connecting plate 3 from separating from the housing 1, thus providing a safety guarantee. The amplification rod 2 has a placement groove 10 on its body, and the connecting rope 11 is located inside the placement groove 10. A cover plate 12 is provided at the opening of the placement groove 10. The cover plate 12 is damped and inserted into the placement groove 10 to seal the opening of the placement groove 10, thereby protecting the connecting rope 11.

[0037] Reference Figure 6 , Figure 7 The diameter of the through hole 17 is larger than the diameter of the wire 9, which reduces the possibility of friction damage between the wire 9 and the inner wall of the through hole 17. A shielding cloth 13 is fixedly installed around the periphery of the wire 9. The shielding cloth 13 is generally made of rubber and has a certain degree of flexibility and sealing performance. The periphery of the shielding cloth 13 is fixedly connected to the inner wall of the through hole 17 by adhesive, which prevents dust, moisture, etc. from entering the housing 1 and causing damage to the internal structure.

[0038] Reference Figure 4 , Figure 8 The wire 9 is fixedly fitted with a first mounting ring 14, which is made of plastic and is fixed to the wire 9 by injection molding. The wire 9 is also slidably fitted with multiple second mounting rings 15, which are also made of plastic and are located on the side of the first mounting ring 14 away from the housing 1. Both the first mounting ring 14 and the second mounting ring 15 are fixedly fitted with a fixing element 16, which is generally a suction cup or adhesive tape; in this embodiment, a suction cup is used. The suction cup is made of rubber and has good adhesion. Using the suction cup, the first mounting ring 14 and the second mounting ring 15 can be fixed to the pipe, thereby fixing and supporting the wire 9 and reducing the wire 9's tendency to move.

[0039] Meanwhile, the length of the wire 9 between the first mounting ring 14 and the housing 1 is greater than the distance between the first mounting ring 14 and the housing 1, which facilitates the movement of the wire 9 with the winding group 6.

[0040] The implementation principle of a micro vibration generator for a pipeline inspection device in this application embodiment is as follows: the first mounting ring 14 and the second mounting ring 15 guide the laying of the wire 9, fix and support the wire 9, and reduce the wire 9 from shaking randomly.

[0041] Example 3.

[0042] This application discloses a miniature vibration generator for a pipeline inspection device.

[0043] Reference Figure 9 , Figure 10 The difference between the micro vibration generator for pipeline inspection device in this embodiment and Embodiment 1 lies in the different movable component 7 and winding assembly 6. The movable component 7 includes a support tube 75, a bearing 76, an insulating ring 77, and a second limiting block 78. The support tube 75 is fixedly installed inside the housing 1. The support tube 75 passes through the magnetic block 5, and the bearing 76 is fixedly sleeved on the support tube 75. The insulating ring 77 is fixedly installed on the outer ring of the bearing 76. The winding assembly 6 is annular with both sides recessed inwards and fixedly connected to the insulating ring 77. The wire 9 is routed along the inside of the support tube 75, and the second limiting block 78 is fixedly installed between the two magnetic blocks 5. The second limiting block 78 is used to limit the rotation angle of the winding assembly 6, ensuring that the number of continuous rotations of the winding assembly 6 in one direction is less than one revolution. The second limiting block 78 is elastic.

[0044] The winding assembly 6 is a ring with inward indentation on both sides, forming an "8" shape. The weight on one side of the winding assembly 6 is greater than the weight on the other side, which facilitates the rotation of the winding assembly 6.

[0045] The implementation principle of a micro vibration generator for a pipeline inspection device according to an embodiment of this application is as follows: when vibrating, the winding group 6 rotates and cuts the magnetic field lines, thereby powering the pipeline inspection device and reducing the trouble of manually charging the wireless sensor battery when it runs out of power.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
