Abstract

This invention discloses an intelligent temperature and humidity monitoring instrument for cold storage, comprising a monitoring instrument, two baffles, a mounting assembly, a shock-absorbing assembly, two sets of ice-breaking assemblies, a switching assembly, and a drainage assembly. Limit blocks are fixedly installed on the upper and lower sides of the monitoring instrument. A vibration sensor and a temperature and humidity sensor are installed inside the monitoring instrument. Two sliding grooves are provided on the baffles, and a flap is rotatably connected to the baffles. This invention utilizes the ice-breaking assemblies.

Description

Technical Field

[0001] This invention relates to the field of temperature and humidity monitoring technology, and in particular to a smart temperature and humidity monitoring device for cold storage. Background Technology

[0002] Temperature and humidity monitors are intelligent monitoring devices used to collect, display, and transmit environmental temperature and humidity parameters. They typically integrate sensor acquisition, data processing, and signal output modules, and can provide real-time feedback on the environmental temperature and humidity status, providing data support for environmental management in scenarios such as warehousing and cold chain. They are core monitoring devices for ensuring the stability of the storage environment.

[0003] As the core storage carrier for temperature-sensitive goods such as fresh food and pharmaceuticals, cold storage facilities have stringent requirements for internal temperature and humidity stability. Temperature and humidity monitoring devices have become standard equipment in cold storage facilities, used to monitor temperature and humidity fluctuations in real time, trigger abnormal warnings, and work with the refrigeration system to maintain the storage environment in compliance with standards, preventing goods from deteriorating and failing due to abnormal temperature and humidity, and meeting the compliance and quality control requirements of cold chain storage.

[0004] However, because the temperature inside the cold storage is below 0°C for a long time, thin ice is easily formed on the surface of the monitoring instrument and the sensor area due to the condensation of ambient water vapor. The thin ice will continue to adhere and accumulate until it completely covers the detection surface of the temperature and humidity sensor, hindering the contact between the sensor and the air inside the cold storage, resulting in distorted and excessively biased temperature and humidity detection data, which affects the normal use of the equipment.

[0005] Accordingly, this application proposes a temperature and humidity monitoring device for intelligent cold storage. Summary of the Invention

[0011] The ice-breaking assembly includes an L-shaped block, a heating box, a rack, a gear, an electric push rod, and several spikes. The L-shaped block is fixedly installed on one end of the baffle, the heating box is fixedly installed on the L-shaped block, the electric push rod is fixedly installed inside the heating box, the rack is slidably connected inside the heating box, the gear is rotatably connected inside the heating box, and several spikes are fixedly connected to the flip plate.

[0012] The drainage assembly includes a mounting plate, a second airbag, several air outlet pipes, and two pressure blocks; the pressure blocks are fixedly mounted on the baffle plate, the second airbag is fixedly mounted on the mounting plate, and the several air outlet pipes are connected to the second airbag.

[0013] The switching assembly includes four first connecting pipes, four second connecting pipes, four rotating cylinders, and several T-shaped pipes; the first connecting pipes are connected to the second airbag, the T-shaped pipes are connected to the first airbag, one end of the rotating cylinder is slidably connected to the first connecting pipe, and the other end is slidably connected to the second connecting pipe.

[0014] Preferably, the mounting assembly includes two limiting strips, two wing plates, two fixing plates, several mounting holes, and four fixing holes; the two wing plates are rotatably connected to the back plate, and the fixing plate is rotatably connected to the baffle.

[0015] Preferably, the two limiting strips are fixedly connected to the two fixing plates respectively. The limiting strips can be attached to the sliding groove after rotating with the fixing plates. The four fixing holes are respectively provided on the fixing plates in pairs, and the plurality of mounting holes are respectively provided on the two fixing plates.

[0016] Preferably, the monitor is slidably connected to the shock absorption assembly, several first airbags are respectively disposed in two sliding grooves, several moving wheels are respectively attached to the monitor, the mounting clip is slidably connected to the back plate, and the sliding rod is slidably connected to the back plate.

[0017] Preferably, the gear is meshed with the rack, the rack is fixedly connected to the output end of the electric push rod, the gear is fixedly connected to the flip plate, the tip of the cone spike can be attached to the surface of the monitor after the flip plate rotates, and the L-shaped block has a built-in power module to supply power to the heating wire in the heating box.

[0018] Preferably, the air outlet pipe is fixedly installed on the mounting plate, and four mounting rods are fixedly connected to the mounting plate. The end of the mounting rod away from the mounting plate is fixedly connected to the baffle. The pressure block can press the second airbag after rotating with the flip plate. An air valve is provided at the connection between the air outlet pipe and the second airbag.

[0019] Preferably, the rotating drum is provided with threads, and a rubber layer is provided at the connection between the rotating drum and the first and second through pipes. The limiting block is slidably connected in the slide groove, the T-shaped tube is provided between the two slide grooves, and the T-shaped tube is fixedly connected to the baffle.

[0020] The present invention has the following beneficial effects:

[0021] 1. Through the shock absorption components, when the cold storage is vibrated due to the operation of the fan or the entry of a forklift, the sliding rod slides inside the back plate, and the spring applies an elastic force to the mounting clip, so that the transfer wheel keeps in contact with the monitor, absorbing the vibration generated by the operation of the cold storage and external collisions. The first airbag absorbs the lateral vibration impact force. When the vibration amplitude is too large, the electric push rod pushes the rack, so that the gear drives the pressure block on the flip plate to rotate less than 90 degrees, so that the pressure block slightly squeezes the second airbag, thereby causing the first airbag to expand, increasing the buffer stroke and shock absorption force, further absorbing excessive vibration, and preventing the monitor from shifting, components from loosening or structural damage.

[0022] Second, through the ice-breaking component, when condensation or thin ice appears on the surface of the monitor, the electric push rod pushes the rack, causing the gear to rotate the cone on the flap by 90 degrees, thereby breaking the thin ice on the knob and sensor area of ​​the monitor surface. This prevents the thin ice from covering the vibration sensor and temperature and humidity sensor, ensuring that the sensor detection area is in normal contact with the air inside the cold storage and maintaining the accuracy of temperature and humidity detection data.

[0023] Third, when condensation or thin ice appears on the surface of the monitor via the drainage component, the electric push rod pushes the rack, causing the gear to rotate the pressure block on the flap by 90 degrees. This causes the pressure block to squeeze the second airbag. After the first airbag is fully inflated, the air valve at the connection between the air outlet pipe and the second airbag opens, blowing away the condensation on the knobs and sensor areas of the monitor surface. This prevents condensation from accumulating on the monitor surface and seeping into the interior along the gaps on the monitor surface, ensuring that the internal vibration sensor, temperature and humidity sensor, and related components are not corroded by moisture.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Example 1:

[0036] Reference Figures 1 to 3 , Figure 6 and Figure 9A smart temperature and humidity monitoring device for cold storage includes a monitoring device 1, two baffles 3, an installation component, a shock absorption component, two sets of ice-breaking components, a switching component, and a drainage component. Limiting blocks 4 are fixedly installed on the upper and lower sides of the monitoring device 1. The limiting blocks 4 cooperate with the sliding grooves 29 to realize the sliding guidance and limiting of the monitoring device 1. A vibration sensor 12 is installed inside the monitoring device 1 to collect vibration signals generated inside the cold storage. A temperature and humidity sensor 13 is installed inside the monitoring device 1 to detect the temperature and humidity parameters of the cold storage environment in real time. Two sliding grooves 29 are provided on the baffles 3. The limiting blocks 4 are slidably connected in the sliding grooves 29. The sliding grooves 29 are used to cooperate with the limiting blocks 4 to realize the sliding movement of the monitoring device 1. A flip plate 2 is rotatably connected to the baffles 3. The flip plate 2 is used to drive the ice-breaking component and the drainage component to move synchronously.

[0037] The on / off assembly is used to control the opening and closing of the gas path, and realizes the coordinated action of multiple mechanisms based on vibration signals and condensation / icing conditions;

[0038] The mounting components include two limiting strips 8, two wing plates 9, two fixing plates 5, several mounting holes 7, and four fixing holes 6. The two wing plates 9 are rotatably connected to the back plate 23. The wing plates 9 are provided with screw holes for connecting with the fixing plates 5. At the same time, the monitor 1 can be mounted on the back plate 23 through the wing plates 9. The fixing plates 5 are rotatably connected to the baffle 3. The fixing plates 5 are used to install on the wall to achieve fixed installation of the monitor 1.

[0039] Two limiting strips 8 are fixedly connected to two fixing plates 5 respectively. After the limiting strips 8 rotate with the fixing plates 5, they can stick to the slide groove 29. The limiting strips 8 are used to close the end of the slide groove 29 to prevent internal parts from sliding out and falling off. Four fixing holes 6 are respectively set on the fixing plates 5 in pairs. The fixing holes 6 can realize the positioning and installation of the fixing plates 5 by bolts. Several mounting holes 7 are respectively set on the two fixing plates 5. The mounting holes 7 realize the fixed connection between the wing plate 9 and the fixing plate 5 by screws.

[0040] In this embodiment, the monitor 1 is first slid through the wing plate 9 onto the back plate 23. At the same time, the limiting block 4 on the monitor 1 also enters the slide groove 29 through the opening of the slide groove 29. Then, the fixing plate 5 is rotated 90 degrees so that the limiting strip 8 is attached to the end of the slide groove 29, thereby closing the slide groove 29. The screw is installed in the mounting hole 7 to achieve a fixed connection between the wing plate 9 and the fixing plate 5. Then, the fixing plate 5 is fixed to the wall through the fixing hole 6 with bolts to complete the installation of the monitor 1.

[0041] Example 2:

[0042] Unlike Example 1, referring to Figure 4 , Figures 5 to 8 This embodiment also has the following further features:

[0043] The shock absorption assembly includes a back plate 23, several rollers 22, several mounting clips 24, several sliding rods 25, several springs 26, and several first airbags 28. The sliding rods 25 are slidably connected inside the back plate 23 and are used to provide sliding guidance for the mounting clips 24. Several mounting clips 24 are respectively fixedly connected to both ends of several sliding rods 25. The mounting clips 24 are used to support the rollers 22 and transmit elastic force. One end of the spring 26 is fixedly connected inside the back plate 23, and the other end is fixedly connected to the mounting clip 24. The spring 26 is used to provide elastic restoring force for the mounting clip 24. The rollers 22 are rotatably connected to the mounting clips 24 and are used to reduce the frictional resistance when the monitor 1 vibrates and slides.

[0044] The monitor 1 is slidably connected to the shock absorption assembly. The monitor 1 can slide up, down, left and right to absorb shock under the support of the shock absorption assembly. Several first airbags 28 are respectively set in two sliding grooves 29. The first airbags 28 are used to cooperate with the sliding to achieve lateral buffering. Several shifting wheels 22 are respectively attached to the monitor 1. The shifting wheels 22 are attached to the monitor 1 to transmit the shock absorption force. The mounting clip 24 is slidably connected to the back plate 23. The mounting clip 24 slides along the inner wall of the back plate 23 to stabilize the movement trajectory. The slide rod 25 is slidably connected to the back plate 23.

[0045] The switching assembly includes four first connecting pipes 15, four second connecting pipes 33, four rotating cylinders 21, and several T-shaped pipes 27. The first connecting pipes 15 are connected to the second airbag 10 and are used to transport the gas discharged from the second airbag 10. The T-shaped pipes 27 are connected to the first airbag 28 and are used to evenly introduce the gas into the first airbag 28. One end of the rotating cylinder 21 is slidably connected to the first connecting pipe 15, and the other end is slidably connected to the second connecting pipe 33. The rotating cylinder 21 is used to connect the first connecting pipe 15 and the second connecting pipe 33. When installing the monitoring device 1, the rotating cylinder 21 needs to be unscrewed to deflate the first airbag 28 to avoid obstructing the limit block 4 and to allow the limit block 4 to smoothly enter the slide groove 29. Then, the rotating cylinder 21 is screwed to connect the first connecting pipe 15 and the second connecting pipe 33, and the second airbag 28 is inflated by injecting gas into the first airbag 10.

[0046] The rotating drum 21 is provided with threads to enhance the connection stability between the rotating drum 21 and the pipeline. The rotating drum 21 is provided with rubber layers at the connection points with the first through pipe 15 and the second through pipe 33 to improve the airtightness of the connection. The T-shaped tube 27 is located between the two sliding grooves 29 and is fixedly connected to the baffle 3. The fixed position of the T-shaped tube 27 ensures the stability of the gas delivery path.

[0047] In this embodiment, when vibrations occur inside the cold storage due to the operation of the fan or the entry of a forklift, the slide bar 25 slides within the back plate 23, and the spring 26 applies an elastic force to the mounting clip 24, causing the transfer wheel 22 to continuously adhere to the monitor 1, absorbing the vibrations generated by the operation of the cold storage and external collisions. The first airbag 28 absorbs the lateral vibration impact force. When the vibration amplitude is too large, the vibration sensor 12 detects the vibration and sends a signal to the control system. The control system causes the electric push rod 32 to push the rack 31, causing the gear 30 to drive the pressure block 17 on the flip plate 2 to rotate less than ninety degrees, thereby causing the pressure block 17 to slightly compress the second airbag 10, which in turn causes the first airbag 28 to expand, increasing the buffer stroke and shock absorption force, further absorbing excessive vibration, and preventing the monitor 1 from shifting, components from loosening, or structural damage.

[0048] It should be noted that since the rotation of the flap 2 driven by the gear 30 is less than 90 degrees, the pressure on the second airbag 10 will not cause the air valve on the air pipe 19 to open, so that gas can be supplied to the first airbag 28.

[0049] Example 3:

[0050] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 Compared to Embodiment 1 and Embodiment 2, in this embodiment:

[0051] The ice-breaking assembly includes an L-shaped block 14, a heating box 18, a rack 31, a gear 30, an electric push rod 32, and several spikes 11. The L-shaped block 14 is fixedly installed at one end of the baffle 3. The L-shaped block 14 is used to support the heating box 18 and has a built-in power module. The heating box 18 is fixedly installed on the L-shaped block 14. The heating box 18 is used to accommodate the transmission components and provide installation space for the heating wire, preventing ice from forming at the meshing point of the gear 30 and the rack 31 and affecting its use. The electric push rod 32 is fixedly installed inside the heating box 18. The electric push rod 32 is used to provide linear driving force. The rack 31 is slidably connected inside the heating box 18. The rack 31 is used to transmit linear motion. The gear 30 is rotatably connected inside the heating box 18. The gear 30 is used to convert linear motion into rotational motion. Several spikes 11 are fixedly connected to the flip plate 2. The spikes 11 are used to pierce the thin ice on the surface of the monitor 1 as the flip plate 2 rotates.

[0052] Gear 30 meshes with rack 31, rack 31 is fixedly connected to the output end of electric push rod 32, gear 30 is fixedly connected to flip plate 2, and the tip of cone spike 11 can stick to the surface of monitor 1 after rotating with flip plate 2. L-shaped block 14 has a built-in power module to supply power to heating wire in heating box 18. The power module is used to provide stable power to heating wire.

[0053] The drainage assembly includes a mounting plate 20, a second airbag 10, several air outlet pipes 19, and two pressure blocks 17. The pressure blocks 17 are fixedly mounted on the baffle 3 and are used to squeeze the second airbag 10 as the flap 2 rotates. The second airbag 10 is fixedly mounted on the mounting plate 20 and is used to discharge gas under pressure. Several air outlet pipes 19 are connected to the second airbag 10 and are used to guide the gas to the surface of the monitor 1.

[0054] The air outlet pipe 19 is fixedly installed on the mounting plate 20. Four mounting rods 16 are fixedly connected to the mounting plate 20. The mounting rods 16 are used to fix the position of the mounting plate 20. The end of the mounting rod 16 away from the mounting plate 20 is fixedly connected to the baffle 3. The pressure block 17 can press the second airbag 10 after rotating with the flip plate 2. An air valve is provided at the connection between the air outlet pipe 19 and the second airbag 10. The air valve is used to control the gas flow.

[0055] In this embodiment, when condensation or thin ice appears on the surface of the monitor 1, the electric push rod 32 pushes the rack 31, causing the gear 30 to rotate the cone 11 on the flap 2 by 90 degrees, thereby breaking the thin ice at the knob and sensor area on the surface of the monitor 1, preventing the thin ice from covering the vibration sensor 12 and the temperature and humidity sensor 13, ensuring that the sensor detection area is in normal contact with the air inside the cold storage, and maintaining the accuracy of the temperature and humidity detection data.

[0056] When the flap 2 rotates, it can also drive the pressure block 17 to rotate 90 degrees, so that the pressure block 17 squeezes the second airbag 10. After the first airbag 28 is fully inflated, the air valve at the connection between the air outlet pipe 19 and the second airbag 10 is opened, blowing away the condensate at the knob and sensor area on the surface of the monitor 1, preventing the condensate from accumulating on the surface of the monitor 1 and seeping into the interior along the gaps on the surface of the monitor 1, and ensuring that the internal vibration sensor 12, temperature and humidity sensor 13 and related components are not corroded by moisture.

[0057] It should be noted that since the gear 30 drives the flap 2 to rotate by 90 degrees, after the first airbag 28 reaches its maximum expansion, the excess gas will be ejected through the air nozzle at the air outlet pipe 19.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
