Description

Technical Field

[0001] This utility model relates to the field of microbial monitoring technology in koji rooms, specifically to a microbial activity monitoring device for koji rooms. Background Technology

[0002] To achieve comprehensive monitoring of different areas and fermentation stages in the koji room, staff will carry a portable case integrating sensors and data acquisition modules to the designated monitoring location. By connecting the monitoring lines of the electronic devices in the portable case, the probes will be placed directly in contact with the koji blocks or inserted into the koji pile environment to transmit key data such as temperature, humidity, and concentration of microbial metabolites in real time, providing a scientific basis for regulating fermentation conditions.

[0003] To facilitate flexible adjustment of the probe position at different monitoring points, the monitoring cable connecting the portable case and the monitoring probe is usually left with a certain length of slack. However, this also brings new problems: the excessively long monitoring cable is prone to loosening and piling up inside the portable case. When the staff opens the case door for monitoring, the monitoring cable may partially slack out of the case. The protruding monitoring cable is easily stepped on or pulled, or damaged by the edge of the case door when it is closed, affecting the stability of data transmission. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention is proposed.

[0005] The purpose of this invention is to effectively solve the problem in the prior art that, due to the excessive length of the monitoring cable, it is easy for it to loosen and accumulate inside the portable case. When the staff opens the case door for monitoring, the monitoring cable may partially loosen and extend out of the case. The extended monitoring cable is easily stepped on or pulled, or is damaged by the edge of the case door when it is closed, which affects the stability of data transmission.

[0007] The inner side of the arc-shaped clamp is provided with a groove that matches the monitoring line.

[0008] Furthermore, a connecting ring is fixedly installed on the side of the worm gear away from the mating gear ring. The worm gear is rotatably connected to the outer wall of the partition through the connecting ring. A worm is rotatably installed on the wall of the partition, and a rotating handle is fixedly installed at one end of the worm. The worm is located between the two worm gears, and both worm gears mesh with the worm.

[0009] Furthermore, a pushing groove is formed on the wall of the drive cylinder, and the pushing groove is arc-shaped. A short rod is integrally formed and connected to the outer wall of the moving rod, and the end of the short rod extends to the outside of the pushing groove.

[0010] Furthermore, a guide groove is provided on the inner wall of the fixed block along the radial direction of the worm gear, and the end of the short rod is slidably connected in the guide groove;

[0011] When the worm gear rotates clockwise, the drive cylinder pushes the moving rod to move in the direction of the worm gear axis, and the two opposing arc-shaped clamping members move closer to each other.

[0012] Furthermore, the partition is symmetrically provided with rectangular through slots, and the two rectangular through slots are respectively located on both sides of the worm gear. The outer side of the portable case is fitted with a case door via a hinge, and the inner edge of the case door is bonded with a rubber sealing ring.

[0013] Furthermore, the partition plate is provided with an auxiliary component, which includes a horizontal block disposed in a rectangular through groove. The opposing surfaces of the two horizontal blocks are provided with arc surfaces, and an inlet channel is formed between the arc surfaces and one side wall of the rectangular through groove. Several sliding rods are fixedly installed on the side of the horizontal block away from the worm gear. Reset members are sleeved on the outer side of each sliding rod. One end of each reset member is connected to the outer wall of the horizontal block, and the other end is connected to the other side wall of the rectangular through groove.

[0014] Furthermore, a first rack is fixedly connected to the outer wall of the horizontal block, a second rack is provided on the top of the first rack, a transmission gear is meshed between the first rack and the second rack, and a friction block is fixedly installed at the end of the second rack near the worm gear, and the friction block is adapted to the shape of the rotating handle.

[0015] Furthermore, a blowing assembly for cleaning the surface of the wire harness is provided on one side of the worm gear. The blowing assembly includes a fixing ring disposed on the outside of the connecting ring and welded to the outer wall of the partition. The inner side of the fixing ring has a number of semi-circular blocks arranged in a ring. The wall of the connecting ring has a number of air outlets arranged in a ring. A piston rod is slidably connected in the air outlet, and one end of the piston rod extends to the outside of the connecting ring.

[0016] Furthermore, a push block is connected to one end of the piston rod away from the axis of the connecting ring, and telescopic components are sleeved on the outer side of the piston rod. One end of several telescopic components is connected to the outer wall of the connecting ring, and the other end is connected to the outer wall of the push block.

[0017] This technical solution has at least the following beneficial effects:

[0018] Several excessively long monitoring wires are passed through the through-hole of the worm gear. The length of the monitoring wires is controlled according to the actual situation to ensure that the monitoring wires do not scatter on the inner bottom wall of the portable case. The worm gear is driven to rotate, causing the fixed block, drive cylinder, and moving rod to rotate synchronously along the axis of the worm gear. At the same time, when the bevel gear rotates around the center of the worm gear, it meshes with the mating gear ring on one side. In this way, the bevel gear drives the drive cylinder to rotate along its own axis and pushes the moving rod and the arc-shaped clamping parts to move towards the axis of the worm gear. That is, the two arc-shaped clamping parts move closer to each other, gathering and tightening the monitoring wires passing through the worm gear. When the monitoring wires are neatly bundled together, as the worm gear continues to rotate, the two arc-shaped clamping parts twist the monitoring wires together in an orderly manner, further defining the position of the monitoring wires and avoiding the possibility of the monitoring wires being damaged by the edge of the case door when closing the case door.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1, referring to Figure 1 - Figure 6This is the first embodiment of the present invention, providing a device for monitoring the microbial activity of a fermentation chamber, including a portable case 1. A partition 2 is fixedly installed inside the portable case 1. Electronic devices for monitoring the microbial activity of a fermentation chamber are installed at the top and bottom of the partition 2 (this is prior art and will not be described in detail). A limiting component 3 for gathering monitoring lines is installed on the partition 2. The limiting component 3 includes worm gears 31 disposed at the top and bottom of the partition 2. The two worm gears 31 are staggered, one in front of the other. 1. A through hole is provided for the monitoring line to pass through. A mating toothed ring 32 is provided on one side of the worm gear 31. Fixed blocks 33 are symmetrically installed on the outer wall of the worm gear 31. A drive cylinder 34 is rotatably installed in the fixed block 33 through a bearing. A moving rod 35 is slidably connected in the drive cylinder 34. A bevel gear 36 is fixedly installed at the end of the drive cylinder 34 away from the axis of the worm gear 31, and the bevel gear 36 meshes with the mating toothed ring 32. An arc-shaped clamping member 37 is fixedly installed at the end of the moving rod 35 close to the axis of the worm gear 31.

[0033] The inner side of the arc-shaped clamp 37 is provided with a groove that matches the monitoring line. The groove can increase the friction between the arc-shaped clamp 37 and the monitoring line, so that when the arc-shaped clamp 37 twists several monitoring lines in the future, the monitoring lines will not be able to complete the orderly twisting action due to slippage.

[0034] Specifically, one end of several excessively long monitoring lines is passed through the through hole of the worm gear 31. The length of the monitoring lines is controlled according to the actual situation to ensure that the monitoring lines do not scatter on the inner bottom wall of the portable case 1. The worm gear 31 is driven to rotate, so that the fixed block 33, the drive cylinder 34 and the moving rod 35 rotate synchronously along the axis of the worm gear 31. At the same time, when the bevel gear 36 rotates around the center of the worm gear 31, it meshes with the mating toothed ring 32 on one side. Thus, the bevel gear 36 drives the drive cylinder 34 to rotate along its own axis and pushes the moving rod 35 and the arc-shaped clamping member 37 to move in the direction of the axis of the worm gear 31. That is, the two arc-shaped clamping members 37 move closer to each other, gathering and tightening the several monitoring lines passing through the worm gear 31. When the monitoring lines are neatly bundled together, as the worm gear 31 continues to rotate, the two arc-shaped clamping members 37 twist the several monitoring lines together in an orderly manner, further limiting the position of the monitoring lines and avoiding the possibility of the monitoring lines being damaged by the edge of the case door 5 when the case door 5 is closed.

[0035] Reference Figure 1 , Figure 2 A connecting ring 38 is fixedly installed on the side of the worm gear 31 away from the mating gear ring 32. The worm gear 31 is rotatably connected to the outer wall of the partition plate 2 through the connecting ring 38. A worm 39 is rotatably installed on the wall of the partition plate 2, and a rotating handle is fixedly installed at one end of the worm 39. The worm 39 is located between the two worm gears 31, and both worm gears 31 mesh with the worm 39.

[0036] Specifically, when it is necessary to gather and limit several monitoring lines inside the portable case 1, the operator drives the worm gear 39 to rotate by turning the handle, so that the two arc-shaped clamps 37 move closer to each other to gather the several monitoring lines. Since the worm gear 39 and the worm wheel 31 have a self-locking feature, after the several monitoring lines are gathered, even if the monitoring line bundle always exerts an outward radial pressure on the arc-shaped clamps 37 in an attempt to return to the untwisted state, it is impossible to open the arc-shaped clamps 37 by itself without rotating the worm gear 39 in the opposite direction.

[0037] Reference Figure 4 , Figure 5 The drive cylinder 34 has a push groove 310 on its wall, and the push groove 310 is arc-shaped. A short rod 311 is integrally formed on the outer wall of the moving rod 35, and the end of the short rod 311 extends to the outside of the push groove 310. A guide groove 312 is formed on the inner wall of the fixed block 33 along the radial direction of the worm wheel 31, and the end of the short rod 311 is slidably connected in the guide groove 312. When the worm wheel 31 rotates clockwise, the drive cylinder 34 pushes the moving rod 35 to move in the direction of the worm wheel 31 axis, and the two opposing arc-shaped clamping members 37 move closer to each other.

[0038] Specifically, the push groove 310 rotates synchronously with the drive cylinder 34, and the push groove 310 pushes the short rod 311 to move away from the bevel gear 36. Under the limiting action of the guide groove 312, the moving rod 35 can drive the arc-shaped clamping member 37 to move linearly in the direction of the worm gear 31 axis.

[0039] Reference Figure 2 Rectangular through slots 4 are symmetrically provided on the partition 2, and the two rectangular through slots 4 are located on both sides of the worm gear 31. The outer side of the portable case 1 is fitted with a case door 5 by a hinge. A rubber sealing ring is glued to the inner edge of the case door 5. The rubber sealing ring has moderate elasticity and can produce reversible deformation when the monitoring line is compressed, so as to prevent the door frame of the case door 5 from scratching the monitoring line.

[0040] Specifically, the connecting wires between the electronic components at the top of the partition 2, when such connecting wires need adjustment, need to pass through two rectangular through slots 4 and through the through hole in the worm gear 31 located at the bottom. In this way, the connecting wires passing through are generally in a "V" shape (e.g., Figure 6 (as shown); the connecting wires between the electronic components at the bottom of the partition 2, when such connecting wires need adjustment, need to pass through two rectangular through slots 4, and through the through hole in the worm gear 31 located at the top. In this way, the wire harness passing through is in an inverted "V" shape (as shown). Figure 6 As shown), this ensures that the wiring harness is all inside the portable case 1 and cannot be loosely extended to the outside of the portable case 1.

[0041] Example 2, refer to Figure 1 - Figure 7This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that an auxiliary component 6 is installed on the partition plate 2. The auxiliary component 6 includes a horizontal block 61 disposed in the rectangular through groove 4. An arc surface 62 is provided on the opposite surface of the two horizontal blocks 61. An inlet channel is formed between the arc surface 62 and one side wall of the rectangular through groove 4. Several sliding rods 63 are fixedly installed on the side of the horizontal block 61 away from the worm gear 31. A reset member 64 is sleeved on the outer side of each sliding rod 63. One end of the several reset members 64 is connected to the outer wall of the horizontal block 61, and the other end is connected to the other side wall of the rectangular through groove 4.

[0042] Specifically, the reset member 64 can be a compression spring or spring sheet commonly used in the prior art. Here, it is preferably a compression spring that can withstand axial pressure, so that when the wire harness changes from a twisted state to a relaxed state, the horizontal block 61 automatically resets under the elastic action of the reset member 64. By setting several reset members 64 to push the same horizontal block 61 linearly, even if one of the horizontal blocks 61 experiences elastic fatigue, the horizontal block 61 can still move closer to the worm gear 31 side when it is not pushed.

[0043] Specifically, when several wires passing through the worm gear 31 are bundled and twisted, the middle section of the wires forms a strand, and the wires on both sides of the worm gear 31 (which were originally hanging naturally) gradually straighten. During the straightening process, the horizontal block 61 and several sliding rods 63 are moved, and the reset member 64 is compressed.

[0044] Reference Figure 6 and Figure 7 A first rack 65 is fixedly connected to the outer wall of the horizontal block 61. A second rack 66 is provided on the top of the first rack 65. A transmission gear 67 is meshed between the first rack 65 and the second rack 66. A cavity is provided on the partition 2 for the first rack 65, the second rack 66 and the transmission gear 67 to move. The transmission gear 67 is rotatably connected to the inner wall of the partition 2 through a shaft. The first rack 65 and the second rack 66 are slidably connected to the inner wall of the partition 2. A friction block 68 is fixedly installed at the end of the second rack 66 near the worm 39, and the friction block 68 is adapted to the shape of the rotating handle.

[0045] Specifically, as the horizontal block 61 moves, it drives the first rack 65 to move synchronously. Under the meshing transmission of the transmission gear 67, the second rack 66 moves in the opposite direction of the first rack 65 (i.e. towards the worm gear 39), causing the friction block 68 to approach the outer wall of the rotating handle. As the friction block 68 continues to move, it presses against the outer wall of the rotating handle, increasing the rotational resistance of the rotating handle, thus limiting the torsional force when adjusting the wire harness and helping to keep the wire harness in a properly coiled and twisted state.

[0046] The remaining structure is the same as that in Example 1.

[0047] Example 3, referring to Figure 1 - Figure 9 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that when the portable case 1 is in use, dust and impurities such as metal shavings and sand particles may adhere to the surface of the wire harness. With the accumulation of time, when the wire harness is bundled or rubs against each other, the surface of the wire harness may become rough, and may even scratch the insulation layer of the wire harness, increasing the risk of wear and breakage between the wire harnesses.

[0048] Reference Figure 2 , Figure 8 and Figure 9 A blowing assembly 7 for cleaning the surface of the wire harness is installed on one side of the worm gear 31. The blowing assembly 7 includes a fixing ring 71 disposed on the outside of the connecting ring 38, and the fixing ring 71 is welded to the outer wall of the partition 2. The inner side of the fixing ring 71 has a number of semi-circular blocks 72 arranged in a ring. The wall of the connecting ring 38 has a number of air outlets 73 arranged in a ring. A piston rod 74 is slidably connected in the air outlets 73, and one end of the piston rod 74 extends to the outside of the connecting ring 38.

[0049] Specifically, the inner wall of the connecting ring 38 can be provided with an annular chamber with several air outlets 73 connected to each other. By the reciprocating movement of the piston rod 74 in the air outlets 73, the outer wall of the wire harness can be blown to remove dust before and after use.

[0050] Reference Figure 8 and Figure 9 The piston rod 74 is connected to a push block 75 at one end away from the axis of the connecting ring 38. Telescopic components 76 are sleeved on the outer side of the piston rod 74. One end of several telescopic components 76 is connected to the outer wall of the connecting ring 38, and the other end is connected to the outer wall of the push block 75.

[0051] Specifically, the push block 75 can be an arc-shaped block or a spherical block, so that when the push block 75 rotates with the worm gear 31 and the connecting ring 38, the push block 75 is squeezed by the wall of the semi-circular block 72 to drive the piston rod 74 to perform reciprocating linear motion; the telescopic component 76 is not specifically limited, but to meet the actual situation, the telescopic component 76 can be a spring, so that the piston rod 74 can move to the inside of the connecting ring 38 and then reset, so that the piston rod 74 can repeatedly inflate the annular cavity of the connecting ring 38.

[0052] Specifically, when the worm gear 39 controls the worm wheel 31 to rotate in the forward or reverse direction, several piston rods 74 rotate synchronously with the worm wheel 31. When the wall of the push block 75 rotates to contact the semi-circular block 72, as the worm wheel 31 continues to rotate, the push block 75 drives the piston rods 74 to move into the inner cavity of the connecting ring 38 to inflate the air, so that the gas passes out from the air outlet 73 and blows onto the outer wall of the wire harness, blowing the dust and impurities on its outer wall to both sides.

[0053] Specifically, by connecting one end of the air intake hose to the output end of the electric air pump and the other end of the air intake hose to the annular chamber connected to the air outlet 73, airflow can be used during the use of the wire harness. The airflow passes through the air outlet 73 and then spreads out from both sides of the connecting ring 38, quickly removing heat from the wire harness and thus improving the heat dissipation efficiency of the wire harness and the inner cavity of the portable case 1.

[0054] The remaining structure is the same as that in Example 2.

[0055] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
