Description

Technical Field

[0001] This utility model relates to the field of instrument vibration reduction technology, and more specifically to a fixing device for a high-precision energy consumption metering instrument in a tobacco factory. Background Technology

[0002] In tobacco production, energy consumption metering is a key link in achieving refined management and controlling production costs. The flow measurement of energy media such as water, steam, and compressed air relies on high-precision energy metering instruments. These instruments typically need to be fixedly installed in the corresponding delivery pipeline system to ensure that the medium flows stably through the metering components inside the instrument, thereby achieving accurate measurement.

[0003] Currently, the industry mostly uses rigid connections to fix energy consumption meters, such as directly connecting both ends of the meter to upstream and downstream pipelines via flanges, or using rigid brackets to fix the meter to the equipment frame. This fixing method can ensure the relative position stability of the meter and pipeline in a static environment, meeting basic installation requirements.

[0004] Vibrations generated during the operation of tobacco factory equipment are transmitted to metering instruments through pipelines, causing the precision metering components inside the instruments (such as impellers and sensors) to be in a state of high-frequency vibration for a long time. This can easily lead to loosening, wear, or calibration drift of the components, seriously affecting the metering accuracy and even shortening the service life of the instruments.

[0005] Therefore, how to provide a new fixing device for high-precision energy consumption metering instruments in tobacco factories, which can avoid the impact of vibrations generated during production on accuracy and lifespan without increasing the complexity of the instrument structure, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the present invention provides a fixing device for a high-precision energy consumption metering instrument in a tobacco factory, which aims to solve the technical problems of decreased instrument accuracy and reduced lifespan caused by the rigid connection method of traditional metering instruments.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A fixing device for a high-precision energy consumption metering instrument in a tobacco factory includes:

[0009] The housing has an input pipe and an output pipe connected to its two sides;

[0010] The outer casing of the measuring instrument is connected to the inner wall of the casing by an elastic support member. The measuring instrument has an input pipe and an output pipe on both sides, which are respectively opposite to the input pipe and the output pipe and are eccentrically arranged.

[0011] The two connecting pipe fittings are used to connect the input pipe one and the input pipe two, as well as the output pipe one and the output pipe two, respectively. The two ends of the connecting pipe fittings are rotatably connected to the two pipe openings at their respective connection positions and are dynamically sealed.

[0012] This invention connects the outer shell of the measuring instrument to the inner wall of the shell via an elastic support member. The connection between the outer shell and the shell is non-rigid. Vibrations experienced by the shell itself are weakened by the elastic support member before being transmitted to the measuring instrument. At the same time, the elastic support member provides support for the measuring instrument while allowing it to have a certain amount of displacement within the shell. The second input pipe and the second output pipe on both sides of the shell are eccentrically arranged relative to the first input pipe and the first output pipe. The two connecting pipes are respectively connected to the corresponding pipes and are rotatably connected at both ends and dynamically sealed. Combined with the displacement provided by the elastic support member, the vibration transmission is converted into relative motion, further weakening external vibrations. This invention can ensure measuring accuracy and extend the instrument's lifespan without increasing the complexity of the instrument structure.

[0013] Preferably, the first input tube and the first output tube are arranged coaxially along an axis, the second input tube and the second output tube are arranged coaxially along an axis, and the first axis and the second axis are arranged parallel to each other.

[0014] Preferably, both sides of the housing are provided with pipe through holes, and the input pipe and the output pipe are respectively elastically sealed to the two pipe through holes.

[0015] Preferably, it further includes buffer rings, with two buffer rings respectively sleeved on the pipe surfaces of the input pipe and the output pipe, and respectively located between the pipe surfaces of the input pipe and the output pipe and the pipe through hole.

[0016] Preferably, one end of the elastic support is hinged to the inner wall of the housing, and the other end is hinged to the outer shell of the metering instrument, and the hinge axes at both ends are arranged parallel to the axis.

[0017] Preferably, there are two elastic support members, symmetrically distributed on both sides of the input pipe.

[0018] Preferably, the distance between axis one and axis two is less than the effective stroke of the elastic support.

[0019] Preferably, the elastic support includes a damping rod, a damping cylinder, and a spring. The first end of the damping rod is hinged to the metering instrument, the first end of the damping cylinder is hinged to the inner wall of the housing, the second end of the damping rod passes through the second end of the damping cylinder and slides and is damped against the inner surface of the damping cylinder, and the spring is sleeved on the damping rod and elastically supported between the first end of the damping rod and the second end of the damping cylinder.

[0020] Preferably, the outer surface of the housing has an observation hole arranged opposite to the dial of the measuring instrument.

[0021] Preferably, the buffer ring is made of rubber.

[0022] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a fixing device for a high-precision energy consumption metering instrument in a tobacco factory, which has the following beneficial effects: the elastic support weakens the vibration transmitted by the shell, reducing the impact of vibration on the precision components inside the metering instrument; the eccentrically arranged and rotatably connected pipes convert vibration transmission into relative motion, further buffering external vibration; the dynamic seal ensures that the medium does not leak while allowing a certain amount of displacement of the metering instrument, solving the problems of decreased accuracy and shortened life caused by traditional rigid connections, ensuring metering accuracy and extending life without increasing the complexity of the instrument.

Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. See the appendix. Figure 1 To be continued Figure 4 and appendix Figure 9 To be continued Figure 11 This utility model discloses a fixing device for a high-precision energy consumption metering instrument in a tobacco factory, comprising: a housing 1, an elastic support 7, and a connecting pipe 5;

[0038] The two sides of the housing 1 are connected to an input tube 2 and an output tube 3;

[0039] The outer shell of the measuring instrument 4 is connected to the inner wall of the housing 1 by an elastic support 7. The measuring instrument 4 has an input pipe 41 and an output pipe 42 on both sides, which are respectively opposite to the input pipe 2 and the output pipe 3 and are arranged eccentrically.

[0040] Two connecting pipe fittings 5 ​​are used to connect input pipe 1 2 and input pipe 2 41, and output pipe 1 3 and output pipe 2 42, respectively. The two ends of the connecting pipe fittings 5 ​​are rotatably connected to the two pipe openings at their respective connection positions and dynamically sealed.

[0041] The connecting pipe 5 converts the vibration transmission between the metering instrument 4 and the outside world into relative rotation, and the elastic support 7 buffers the vibration from the outside world.

[0042] The connection structure between input tube 1 2 and input tube 2 41 and connecting pipe 5 is the same as the connection structure between output tube 1 3 and output tube 2 42 and connecting pipe 5. The following description takes the connection structure between input tube 1 2 and input tube 2 41 and connecting pipe 5 as an example.

[0043] Specifically, it also includes sealing rings 8. Rotating rings 22 and 412 are fixedly connected to the opposite ends of input pipe 2 and input pipe 41, respectively. Rotating ring 22 is coaxially arranged with input pipe 2, and rotating ring 412 is coaxially arranged with input pipe 41. Sealing ring grooves 21 and 411 are respectively formed around the circumference of the pipe surfaces of input pipe 2 and input pipe 41 near their opposite ends. Two sealing rings 8 are respectively fitted into sealing ring grooves 21 and 411. The first and second ends of the connecting pipe 5 are respectively fitted onto the opposite ends of input pipe 2 and input pipe 41. On the outer periphery of the opposite end, the first end of the connecting pipe 5 is provided with a rotating groove 504 that is rotatably connected to the rotating ring 22 and a sealing ring groove 502 that is rotatably connected to the sealing ring groove 21. The sealing ring 8 is elastically sealed between the sealing ring groove 21 and the sealing ring groove 502. The second end of the connecting pipe 5 is provided with a rotating groove 503 that is rotatably connected to the rotating ring 412 and a sealing ring groove 501 that is rotatably connected to the sealing ring groove 411. Another sealing ring 8 is elastically sealed between the sealing ring groove 411 and the sealing ring groove 501.

[0044] Specifically, a flow channel 505 is provided inside the connecting pipe 5 to connect the first end and the second end of the connecting pipe 5.

[0045] See appendix Figure 6 and attached Figure 7 Input tube 2 and output tube 3 are arranged coaxially along the axis, input tube 41 and output tube 42 are arranged coaxially along axis 2, and axis 1 and axis 2 are arranged parallel.

[0046] Specifically, the connecting pipe 5 is divided into a first half-shell 51 and a second half-shell 52 by plane one. Both axis one and axis two are located in plane one. The first half-shell 51 and the second half-shell 52 have the same structure. Locking plates 506 are fixedly connected to the opposite surfaces of the first half-shell 51 and the second half-shell 52. The locking plates 506 corresponding to the first half-shell 51 and the second half-shell 52 are respectively provided with screw through holes and threaded bottom holes. The screws pass through the screw through holes and are spirally connected to the threaded bottom holes. There are multiple locking plates 506, which are evenly arranged on the opposite surfaces of the first half-shell 51 and the second half-shell 52.

[0047] See appendix Figure 4 Both sides of the shell 1 are provided with pipe through holes 11, and the input pipe 2 and the output pipe 3 are respectively elastically sealed to the two pipe through holes 11.

[0048] In this embodiment, a buffer ring 6 is also included. Two buffer rings 6 are respectively disposed on the pipe surfaces of the input pipe 2 and the output pipe 3, and are respectively located between the pipe surfaces of the input pipe 2 and the output pipe 3 and the pipe through hole 11.

[0049] See appendix Figure 5 One end of the elastic support 7 is hinged to the inner wall of the housing 1, and the other end is hinged to the outer shell of the metering instrument 4, with the hinge axes at both ends arranged parallel to axis 1.

[0050] See appendix Figure 8 There are two elastic support members 7, symmetrically distributed on both sides of the input pipe 41. This symmetrical arrangement ensures that the metering instrument 4 is subjected to balanced forces, preventing tilting due to unilateral forces during vibration and guaranteeing instrument stability.

[0051] In some embodiments, the distance between axis one and axis two is less than the effective stroke of the elastic support 7.

[0052] In some other embodiments, the elastic support 7 includes a damping rod 71, a damping cylinder 72, and a spring 73. The first end of the damping rod 71 is hinged to the metering instrument 4, the first end of the damping cylinder 72 is hinged to the inner wall of the housing 1, the second end of the damping rod 71 passes through the second end of the damping cylinder 72 and slides and is damped against the inner surface of the damping cylinder 72, and the spring 73 is sleeved on the damping rod 71 and elastically supported between the first end of the damping rod 71 and the second end of the damping cylinder 72.

[0053] Specifically, a baffle 711 is fixedly connected to the rod surface of the damping rod 71 near its first end, and a baffle 721 arranged opposite to the baffle 711 is fixedly connected to the second section of the damping cylinder 72. The two ends of the spring 73 are elastically supported between the baffle 711 and the baffle 721.

[0054] More specifically, the damping rods 71 ​​corresponding to the two elastic support members 7 are arranged coaxially, and their axes pass through the center of gravity of the metering instrument 4.

[0055] In some specific embodiments, the outer surface of the housing 1 is provided with an observation hole 12 arranged opposite to the dial of the metering instrument 4. This allows for observation of metering data without opening the housing 1, reducing the disruption of the sealed environment inside the housing caused by opening the cover, improving operational convenience, and facilitating real-time monitoring of energy consumption data.

[0056] In some other specific embodiments, the buffer ring 6 is made of rubber. Rubber, with its excellent elasticity and deformation capacity, effectively absorbs vibration energy and enhances the buffering effect between the pipe and the housing 1.

[0057] The specific principle of the fixing device for a high-precision energy consumption metering instrument in a tobacco factory provided in this embodiment is as follows: The fixing device weakens vibration through a three-stage vibration reduction structure, as detailed below:

[0058] The first stage is the elastic buffer between the shell and the pipe. Rubber buffer rings 6 are sleeved between the pipe through holes 11 on both sides of the shell 1 and the input pipe 2 and the output pipe 3. The elastic deformation of the rubber absorbs the vibration energy transmitted from the shell 1 to the pipe, reducing the direct transmission of vibration from the shell to the pipe.

[0059] The second stage is the double damping of the elastic support. The outer shell of the metering instrument 4 is connected to the inner wall of the shell 1 through the elastic support 7. The support consists of a damping rod 71, a damping cylinder 72 and a spring 73. The spring 73 initially buffers the vibration through elastic deformation, and the sliding damping connection between the damping rod 71 and the damping cylinder 72 consumes vibration energy through friction and suppresses resonance.

[0060] The third stage is the vibration conversion of the eccentric pipe and the rotating connection. The input pipe 41 and output pipe 42 of the metering instrument 4 are eccentrically parallel to the input pipe 2 and output pipe 3 of the housing. The two ends are rotated and dynamically sealed through the connecting pipe fitting 5. When the housing 1 and the metering instrument 4 are relatively displaced due to vibration, the eccentric structure and the rotating connection will convert the rigid vibration impact into the relative rotation of the pipe fitting and the pipe, avoid stress concentration, and further block the vibration transmission path.

[0061] The three-stage vibration reduction structure works synergistically to effectively reduce the impact of tobacco factory equipment vibration on the internal precision components of metering instrument 4, ensuring measurement accuracy and extending the life of metering instrument 4.

[0062] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
