Description

Technical Field

[0001] This utility model belongs to the field of data transmission technology, specifically relating to a wireless module for optimizing data transmission of a rotor flow meter. Background Technology

[0002] A rotor velocity meter is an instrument that calculates the velocity of a water flow point by measuring the rotational speed of a rotor driven by water flow. Its basic principle is that there is a stable linear relationship between the flow velocity and the rotor speed. When the rotor velocity meter finishes measuring the flow velocity of the water flow, it needs to transmit the measured data to the corresponding device through a wireless data transmission module.

[0003] The wireless data transmission module is installed in the corresponding installation compartment inside the flow meter. Generally, the wireless data transmission module is installed inside the installation compartment by fixing screws. In order to prevent the wireless data transmission module from shifting when tightening the fixing screws, the module needs to be pressed down while tightening the fixing screws. Due to the limited space inside the installation compartment, the installation of the module is time-consuming and laborious, which reduces the efficiency of the module installation to a certain extent. Utility Model Content

[0004] The purpose of this invention is to provide a wireless module for optimizing data transmission of a rotor flow meter. The module body can be fixed in position before screwing in by using the cooperation of the sleeve slot and the positioning block, preventing displacement of the module body during screwing. At the same time, there is no need to press the module body during screwing, making the installation of the module body more convenient and faster, and reducing the difficulty of module body installation.

[0005] The specific technical solution adopted in this utility model is as follows: A wireless module for optimizing data transmission of a rotor flow meter includes a mounting compartment located inside the rotor flow meter body. A module body is disposed inside the mounting compartment. Mounting plates are fixedly mounted on both sides of the module body at positions flush with the back. Insertion holes are formed through the mounting plates near the top and bottom of their front surfaces. Fixing screws are inserted into the insertion holes. Screw holes are formed inside the mounting compartment at positions corresponding to the fixing screws. The module body is fixedly mounted inside the mounting compartment by the cooperation of the fixing screws and screw holes. A through-slot is formed in the middle of the front surface of the mounting plate. A positioning block is fixedly connected inside the mounting compartment at a position corresponding to the through-slot. The positioning block passes through the through-slot, causing the through-slot to be damped and fitted onto the outside of the positioning block.

[0006] In a preferred embodiment, a mounting groove penetrating the interior of the positioning block is provided at the center of the front side of the positioning block. An elastic component is provided at the center of the mounting groove. A limiting rod with an "L" shape is fixedly connected to the top and bottom of the elastic component. A limiting tube is fixedly connected to the outer wall of the fixing screw near the front side. A ring-shaped limiting groove is provided on the outer side of the limiting tube. One end of the limiting rod extends to the front side of the positioning block, and the other end extends to the back side of the mounting piece and is inserted into the limiting groove.

[0007] In a preferred embodiment, the outer diameter of the limiting tube is smaller than the diameter of the insertion hole.

[0008] In a preferred embodiment, the elastic component includes a sliding sleeve, which is fixedly installed at the middle position inside the mounting groove. A sliding post is provided at the middle position inside the sliding sleeve, and springs are fixedly connected to both ends of the sliding post. The two springs extend to the outside of the sliding sleeve and are fixedly connected to a limiting rod. The outer wall of the spring is slidably connected to the inner wall of the sliding sleeve.

[0009] In a preferred embodiment, the limiting rod has a hollow internal structure.

[0010] In a preferred embodiment, a limiting member is fixedly connected to the end of the limiting rod away from the sliding sleeve. The limiting member has a hemispherical structure, and the end of the limiting rod is inserted into the inside of the limiting groove through the limiting member. The arc-shaped surface of the limiting member faces the front, and the vertical surface of the limiting member contacts the side wall of the limiting groove.

[0011] The technical effects achieved by this utility model are as follows: This utility model completes the initial positioning of the module body through the cooperation of the positioning block and the socket through slot. At this time, the fixing screw can be screwed to complete the installation of the module body. Since the initial positioning of the module body has been completed, the module body will not move during the screwing process. Therefore, there is no need to press the module body during the screwing process, which makes the installation of the module body in a limited space easier, reduces the installation difficulty of the module body, and improves the installation efficiency of the module body. This utility model uses the cooperation of a limiting groove and a limiting component to limit the fixing screws, thereby preventing the fixing screws from loosening due to shaking in the water flow. This makes the installation of the module body more secure, reduces the probability of the module body falling off the installation point, ensures the normal operation of the module body, and thus ensures the normal operation of data transmission, avoids unexpected interruption of data transmission, and thus protects and optimizes data transmission.

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0016] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0017] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0018] Please see the appendix Figures 1 to 9 As shown, this utility model provides a wireless module for optimizing data transmission of a rotor flow meter, including a mounting chamber 1 located inside the rotor flow meter body. A module body 2 is disposed inside the mounting chamber 1. Mounting plates 3 are fixedly mounted on both sides of the module body 2 at positions flush with the back. Insertion holes 4 are provided through the mounting plates 3 near the top and bottom on the front side. Fixing screws 6 are inserted into the insertion holes 4. Screw holes 9 are provided inside the mounting chamber 1 at positions corresponding to the fixing screws 6. The module body 2 is fixedly installed inside the mounting chamber 1 by the cooperation of the fixing screws 6 and the screw holes 9. A connecting groove 5 is provided in the middle of the front side of the mounting plate 3. A positioning block 7 is fixedly connected inside the mounting chamber 1 at a position corresponding to the connecting groove 5. The positioning block 7 passes through the inside of the connecting groove 5, causing the connecting groove 5 to be damped and fitted onto the outside of the positioning block 7.

[0019] With the above structure, when the module body 2 needs to be installed, the sleeve through groove 5 on the mounting plate 3 can be damped and fitted onto the outside of the positioning block 7. The initial positioning of the module body 2 is completed by the cooperation between the positioning block 7 and the sleeve through groove 5. At this time, the fixing screw 6 can be screwed to complete the installation of the module body 2. Since the initial positioning of the module body 2 has been completed, the module body 2 will not be displaced during the screwing of the fixing screw 6. Therefore, there is no need to press the module body 2 during the screwing of the fixing screw 6, which makes the installation of the module body 2 in a limited space easier, reduces the installation difficulty of the module body 2, and thus improves the installation efficiency of the module body 2.

[0020] In a preferred embodiment, please refer to Figures 3 to 9 A mounting groove 11 is provided in the middle of the front of the positioning block 7, which penetrates the interior of the positioning block 7. An elastic component is provided in the middle of the mounting groove 11. A limiting rod 16 with an "L" shape is fixedly connected to the top and bottom of the elastic component. A limiting tube 8 is fixedly connected to the outer wall of the fixing screw 6 near the front. The outer diameter of the limiting tube 8 is larger than the diameter of the screw hole 9. A ring-shaped limiting groove 10 is provided on the outer side of the limiting tube 8. One end of the limiting rod 16 extends to the front of the positioning block 7, and the other end extends to the back of the mounting piece 3 and is inserted into the interior of the limiting groove 10.

[0021] In this embodiment, during the tightening of the fixing screw 6, as the fixing screw 6 is tightened and with the cooperation of the elastic component, the end of the limiting rod 16 near the limiting groove 10 is inserted into the inside of the limiting groove 10. Thus, the fixing screw 6 is limited by the cooperation of the limiting groove 10 and the limiting rod 16, preventing the fixing screw 6 from loosening due to shaking in the water flow. This makes the installation of the module body 2 more secure, reduces the probability of the module body 2 falling off the installation point, ensures the normal operation of the module body 2, and thus ensures the normal transmission of data, avoids unexpected interruption of data transmission, and thereby ensures and optimizes data transmission.

[0022] Secondly, please refer to it again. Figure 5 and Figure 8 The outer diameter of the limiting tube 8 is smaller than the diameter of the insertion hole 4.

[0023] The above structure ensures that the fixing screw 6 and the limiting tube 8 can pass smoothly through the insertion hole 4. Secondly, please refer to the following as well. Figure 6 and Figure 7 The elastic component includes a sliding sleeve 13, which is fixedly installed in the middle position inside the mounting groove 11. A sliding post 14 is provided in the middle position inside the sliding sleeve 13. Springs 15 are fixedly connected to both ends of the sliding post 14. The ends of the two springs 15 that are opposite to each other extend to the outside of the sliding sleeve 13 and are fixedly connected to the limiting rod 16. The outer wall of the spring 15 is slidably connected to the inner wall of the sliding sleeve 13.

[0024] In the above structure, as the fixing screw 6 is tightened, the limiting tube 8 gradually comes into contact with the end of the limiting rod 16 and squeezes the end of the limiting rod 16. At this time, the limiting rod 16 presses the spring 15, the spring 15 slides into the sliding sleeve 13 and the sliding column 14 retracts. As the fixing screw 6 is continuously tightened, the end of the limiting rod 16 gradually corresponds to the position of the limiting groove 10. At this time, due to the elastic force of the sliding column 14, the end of the limiting rod 16 is reset, so that the end of the limiting rod 16 is inserted into the inside of the limiting groove 10. The limiting rod 16 and the limiting groove 10 cooperate to limit the fixing screw 6.

[0025] In a preferred embodiment, please refer to Figure 6 The limit rod 16 has a hollow internal structure.

[0026] In this embodiment, the weight of the limiting rod 16 is reduced, making it easier for the limiting rod 16 to move.

[0027] Secondly, please refer to it again. Figure 6 and Figure 8The end of the limiting rod 16 away from the sliding sleeve 13 is fixedly connected to the limiting member 17. The limiting member 17 has a hemispherical structure, and the end of the limiting rod 16 is inserted into the inside of the limiting groove 10 through the limiting member 17. The arc-shaped surface of the limiting member 17 faces the front, and the vertical surface of the limiting member 17 is in contact with the side wall of the limiting groove 10. The arc-shaped surface of the limiting member 17 is made of elastic material, and the vertical surface of the limiting member 17 is made of rigid material.

[0028] In the above structure, when the fixing screw 6 is tightened, the limiting tube 8 on the fixing screw 6 gradually contacts the arc-shaped surface of the limiting member 17 on the limiting rod 16. As tightening continues, the limiting tube 8 gradually presses against the arc-shaped surface of the limiting member 17 at the end of the limiting rod 16, causing the limiting member 17 to push the spring 15 into the sliding sleeve 13 via the limiting rod 16. At this time, the sliding column 14 is compressed. As tightening continues, the position of the limiting member 17 gradually corresponds to the position of the limiting groove 10. Due to the elastic force of the sliding column 14, the spring 15 and... When the limiting rod 16 is reset, the limiting member 17 is inserted into the limiting groove 10, and the vertical surface of the limiting member 17 contacts the inner wall of the limiting groove 10. At this time, the fixing screw 6 can be limited by the cooperation between the limiting groove 10 and the limiting member 17, thereby preventing the fixing screw 6 from loosening due to shaking in the water flow. This makes the installation of the module body 2 more secure, reduces the probability of the module body 2 falling off the installation point, ensures the normal operation of the module body 2, and thus ensures the normal operation of data transmission, avoids unexpected interruption of data transmission, and thus ensures and optimizes data transmission.

[0029] The working principle of this utility is as follows: When installing the module body 2, the sleeve through groove 5 on the mounting plate 3 can be damped and fitted onto the positioning block 7 to complete the initial positioning of the module body 2. At this time, the fixing screws 6 can be inserted one by one into the insertion hole 4, and the fixing screws 6 can be screwed on so that the end of the fixing screw 6 is gradually screwed into the screw hole 9 to complete the installation. During the screwing process of screw hole 9, the surface of limit tube 8 gradually contacts the arc surface of limit member 17. As the screwing proceeds, limit tube 8 gradually presses limit member 17, causing limit member 17 to slide into sliding sleeve 13 via limit rod 16 and spring 15. Sliding column 14 is compressed. When the back of limit tube 8 contacts the inner wall of installation chamber 1, the position of limit member 17 corresponds to the position of limit groove 10. At this time, due to the elastic force of sliding column 14, limit rod 16 and limit member 17 are reset. At this time, the top of limit member 17 is inserted into the inside of limit groove 10, and the vertical surface of limit member 17 contacts the inner wall of limit groove 10. Thus, the mutual cooperation between limit member 17 and limit groove 10 limits the fixing screw 6, preventing the fixing screw 6 from loosening due to the impact and shaking of water flow.

[0030] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model shall be implemented according to conventional methods in the art unless otherwise specified or limited.
