Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and in particular to an environmental monitoring device for cold chain warehousing. Background Art

[0002] Cold chain warehousing is a special form of warehousing, mainly used to store items with strict temperature requirements, such as fresh agricultural products. It uses refrigeration equipment and insulation facilities to maintain a specific low-temperature environment in the storage space to inhibit the growth of microorganisms, slow down the deterioration of items, and ensure the quality and safety of items.

[0003] In the field of modern cold chain warehousing, with the growing demand for storage of goods such as fresh agricultural products that have stringent requirements on the storage environment, the scale and importance of cold chain warehousing have become increasingly prominent. During the storage process, these goods are extremely sensitive to environmental parameters such as temperature, humidity, and gas composition. Minor environmental changes, such as temperature fluctuations, excessive or low humidity, and increased concentrations of harmful gases, may have a serious impact on the quality and safety of the goods, causing the goods to deteriorate, be damaged, or even lose their use value. In order to ensure that the goods in the cold chain warehouse are always in a suitable storage environment, accurate and real-time environmental monitoring is crucial. As a key component of the cold chain warehousing system, the environmental monitoring device can continuously monitor and collect data on various environmental parameters in the storage space. By providing timely and accurate feedback on environmental information, staff can take corresponding regulatory measures based on the monitoring results to maintain a stable storage environment, thereby ensuring the quality of the goods and reducing losses caused by environmental factors.

[0004] The prior art publication number is CN115684474A, which provides an environmental monitoring device for cold chain storage, including a mounting seat, characterized in that: a rotating column is provided on the surface of the mounting seat and is connected to the mounting seat for limited rotation, the top of the rotating column is fixedly connected to a fixing frame, a detector for detecting temperature is fixed on the fixing frame, a mounting frame is fixed on the outer contour of the detector near the probe end, a detection mechanism for performing air sampling and detection on the storage environment is set on the mounting frame, the detection mechanism includes a mounting block, a groove is provided on the surface of the mounting block, and a vacuum cylinder for sampling is fixed through the groove, a sensor for detecting ethylene concentration is set in the vacuum cylinder, a spring is sleeved on the outer contour of the piston rod of the vacuum cylinder, and the end of the piston rod of the vacuum cylinder is fixedly connected to a slider connected to the groove in the mounting block for limited sliding. The invention has the advantages of facilitating the detection of ethylene concentration in the air and fruit temperature in the storage environment, and timely cleaning of the detection probe, thereby solving the problems raised in the background technology.

[0005] Although the above-mentioned existing technology is convenient for sampling and detecting ethylene gas in the storage environment, the scope of sampling and detection is small. In the existing warehousing process, fresh goods are generally stacked on shelves in a certain order, and the detection heads for detecting whether the goods are corrupt are generally fixed at a certain location. However, due to the low temperature and poor air circulation in the warehouse, it is difficult for the detection heads to accurately and timely locate the corruption points of the goods. Failure to locate the problematic goods in time may cause large-scale corruption, increasing losses.

[0006] It can be seen that an environmental monitoring device for cold chain warehousing is needed to solve the problems mentioned in the above background technology that the existing detection equipment is fixedly installed, has a small detection range, and the detection head is difficult to accurately locate the source of spoiled goods.

Together, the goods on each layer of the shelf can be detected, and the transverse component will stay at a fixed point during the transverse movement of the shelf, making it convenient for the detection head to detect goods at different positions on the shelf. The detection trajectory of the detection head is rectangular, and because the odor of rotten goods is most likely to be exposed from the edge seam of the packaging, the rectangular movement trajectory increases the chance of odor capture. The device has a large movement range and accurate fixed-point capture, which effectively improves the environmental monitoring conditions of the cold storage, significantly reduces the risk of difficulty in timely detection of cargo spoilage due to low temperature environment and poor air circulation, avoids large-scale cargo loss caused by monitoring lag, and effectively guarantees the quality and safety of stored goods.

With the help of the mechanical structure, the lifting block will achieve intermittent pauses during the lifting process, and the pause positions just correspond to the partition positions. At this time, the detection head has ample time to move along the partition to carry out detailed inspection of the goods, and the pause component will drive the transverse movement component to gradually expand. During this process, the detection head will gradually move forward with the expansion of the transverse movement component. The mechanical structure inside the pause component can enable the detection head to achieve multiple fixed-point stops during the forward movement, which provides convenience for the detection head to conduct comprehensive inspection of goods at different positions of the partition. The expansion and recovery power of the transverse movement component are both derived from the drive motor. Through the unique mechanical structure design, the drive motor does not need to rotate back and forth to efficiently complete the expansion and recovery actions of the transverse movement component, which not only ensures the smooth progress of the detection process, but also improves the operation efficiency of the entire system.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

A meshing second intermediate gear 408 is provided on one side of the first intermediate gear 407, and a second intermediate short shaft 410 is provided above the second intermediate gear 408. A fourth long shaft 411 is hinged on one side of the second intermediate short shaft 410, and the second intermediate gear 408 is connected to the tail short shaft 412 through the third long shaft 409, and the tail short shaft 412 is located on one side of the detection component 5.

[0022] In this embodiment, a controller is installed in the device. The controller and the electronic components in the device are electrically connected to facilitate direct control. Since the device needs to be installed in a low-temperature cold storage, the parts in the device are made of low-temperature resistant materials, and the electronic components running in the device are also low-temperature resistant products. Since the device can drive the detection head 506 to move over a large range, the device is suitable for installation on storage shelves in the cold storage. The shape of the shelf is generally as shown in the accompanying figure. The shelf is provided with partitions, and goods can be placed on the partitions in an orderly manner. Some fresh or frozen goods may spoil after being stored for a period of time. The smell of spoilage can be detected by an ethylene gas detection sensor. The detection head in the device can be an ethylene gas detection sensor. Once ethylene gas is detected, an alarm will be sent via an external Bluetooth or wireless method, prompting the staff to remove the spoiled goods to avoid further losses. In some rental cold storage environments, the device can be used as soon as the goods are placed on the cold storage shelves. The device detects whether the goods are spoiled and determines whether the original condition of the goods delivered to the warehouse is intact, avoiding spoilage after storage for a period of time and the shirking of responsibility between the leasing parties.

[0023] Specifically, the lifting component 2 includes a lifting motor 201, and the output end of the lifting motor 201 is connected to a protrusion 202, one side of the protrusion 202 is connected to a roller 203, and the roller 203 is arranged at one end of the conical plate 204, and a positioning block 205 is installed in the middle position of the conical plate 204, and a base plate 206 is connected below the end of the conical plate 204 away from the roller 203, one end of the base plate 206 is connected to a locking block 208, and a limit block 207 is hinged above the base plate 206, and an articulated tooth plate 209 is hinged at the eccentric point of the protrusion 202, and a screw gear 210 meshing with it is provided on one side of the articulated tooth plate 209, and a limit groove 211 matching the limit block 207 is provided above the articulated tooth plate 209.

[0024] In this embodiment, the lifting motor 201 can be a servo motor. The purpose of starting the lifting motor 201 is to drive the screw rod 212 to rotate, and then drive the lifting block 213 to move up and down. However, a waiting time is required during the detection process, so the lifting block 213 cannot be in a moving state all the time. Therefore, a bump 202, a roller 203, a screw gear 210 and other structures are added between the lifting motor 201 and the screw rod 212, so that the lifting motor 201 can make the screw rod 212 rotate intermittently without repeated starting and stopping. After starting the lifting motor 201, the bump 202 will be driven to rotate. There is a height difference between the part where the outer side of the bump 202 contacts the roller 203, resulting in a height difference between the roller 203 when the bump 202 rotates, and the conical plate 204 is similar to a seesaw structure. When the position of one end is raised, the other end will The lowering is carried out by utilizing this displacement to cause the bottom plate 206 and the limit block 207 to be displaced to a certain extent. The displacement of the bottom plate 206 can cause the locking block 208 to be stuck in the tooth gap of the screw gear 210 or to be away from the screw gear 210. The limit block 207 also plays a limiting function on the articulated tooth plate 209, which can make the articulated tooth plate 209 engage or disengage with the screw gear 210. In this way, the articulated tooth plate 209 can intermittently contact and engage with the screw gear 210, thereby causing the screw gear 210 to rotate intermittently. If the more protruding side of the protrusion 202 is called the convex surface, and the less protruding side is called the concave surface, then the articulated tooth plate 209 will only contact the screw gear 210 when the roller 203 contacts the convex surface, and the articulated tooth plate 209 will not contact the screw gear 210 when the roller 203 contacts the concave surface.

[0025] Specifically, the bottom plate 206 is located below the screw gear 210, and the locking block 208 is located on one side of the screw gear 210. The bottom end of the screw gear 210 is connected to the screw rod 212, and a lifting block 213 matching it is provided on the outside of the screw rod 212. A mounting groove is opened on one side of the interior of the shelf 1, and the screw rod 212 passes through the mounting groove and rotates inside it, and the lifting block 213 rises and falls along the inner wall of the mounting groove.

[0026] In this embodiment, a through shaft is provided at the bottom end of the protrusion 202, and a spring is provided between the through shaft and the bottom of the conical plate 204, so that the roller 203 can maintain a state of being in contact with the side of the protrusion 202. A fixed block is provided below the positioning block 205, and a shaft is provided between the fixed block and the positioning block 205, which can pass through the center position of the conical plate 204, so the conical plate 204 rotates with the positioning block 205 as the center point. In order to better use the device, the screw rod 212 can adopt a self-locking screw rod structure, such as a trapezoidal screw rod. When the lifting block 213 is stationary, the structure of the screw rod 212 itself prevents the lifting block 213 from being displaced under the action of gravity.

[0027] Specifically, a fixed plate is installed on the rear side of the end gear 401, and the central axis passes through the fixed plate and extends to its outside. The first long axis 402 is arranged on the outside of the central axis, one end of the positioning short axis 403 is positioned on the fixed plate, and the other end is hinged to the second long axis 404. A back plate 406 is provided on the rear side of the first intermediate gear 407 and the second intermediate gear 408, one end of the first intermediate short axis 405 and the second intermediate short axis 410 are both fixed on the back plate 406, and the other end of the first intermediate short axis 405 is hinged to the second long axis 404, the other end of the second intermediate short axis 410 is hinged to the fourth long axis 411, and the other end of the fourth long axis 411 is hinged to the tail short axis 412.

[0028] In this embodiment, the rotation range of the first long axis 402 is 0-90 degrees, and a parallelogram-like structure is formed between the positioning short axis 403, the second long axis 404, the first intermediate short axis 405 and the first long axis 402. During the movement, the positioning short axis 403 and the first intermediate short axis 405 always remain parallel. The second intermediate short axis 410, the fourth long axis 411, the tail short axis 412 and the third long axis 409 can also be regarded as a group of parallelogram structures. The parallelogram structure and motion trajectory of the first long axis 402 are the same as the quadrilateral structure of the third long axis 409. When the transverse movement component 4 is expanded or stored as a whole, the tail short axis 412 drives the detection component 5 to move in a straight line, so the detection component 5 can move while remaining close to the cargo.

[0029] Specifically, a central axis is provided in the middle of the first intermediate gear 407 and the second intermediate gear 408, and the axis is connected to the back plate 406 through a bearing. One end of the first long axis 402 is provided on the outside of the central axis of the first intermediate gear 407, and one end of the third long axis 409 is provided on the outside of the central axis of the second intermediate gear 408, and the other end of the third long axis 409 is hinged to the tail short axis 412, and a detection component 5 is installed at the middle position of the tail short axis 412.

[0030] In this embodiment, the lengths of the first long axis 402, the second long axis 404, the third long axis 409 and the fourth long axis 411 determine the length of the transverse movement component 4 after it is unfolded. The accompanying drawings do not limit the actual length. For comprehensive testing, a length that matches the length of the partition in the shelf 1 can be used. Because they need to bear the weight of the detection component 5, the first long axis 402, the second long axis 404 and the third long axis 409 can be made of metal with strong pressure resistance. When the transverse movement component 4 is unfolded or stored, a certain amount of longitudinal space is required. Because the goods have been stacked, the unfolding and storing actions of the transverse movement component 4 will not affect the goods.

[0031] Specifically, the detection component 5 includes a moving motor 501, and the output end of the moving motor 501 is connected to a hinge shaft 502, one end of the hinge shaft 502 is connected to an internal gear 503, the internal gear 503 is located inside the outer ring gear 504 and rotates, and the outer ring gear 504 and the internal gear 503 are meshed, the bottom end of the internal gear 503 is connected to a displacement shaft 505, and one end of the displacement shaft 505 is installed with a detection head 506, and the detection head 506 moves along a rectangular trajectory for detection.

[0032] In this embodiment, if the depth of the goods is long, a set of moving mechanisms can be installed between the tail short axis 412 and the detection component 5, which can be composed of a gear rack. When the gear rotates, the detection component 5 installed with the rack is driven to move progressively, which is convenient for entering the shelf and detecting the goods with a long depth. The detection component 5 can also be installed sideways so that the detection head 506 detects the front of the goods. In this way, when lifting, the movement of the detection component 5 will not be restricted by the interlayer in the shelf 1. In addition, the first long axis 402, the second long axis 404, the third long axis 409 and the fourth long axis 408 in the transverse movement component 4 can also be extended. The length of the long axis 411 is provided on the side panel at one end of the shelf 1, and the fully expanded transverse moving component 4 will drive the detection component 5 to pass through the through slot, and then descend into the partition from the through slot of the next set of side panels to detect the goods on the next set of partitions. In this embodiment, the detection head 506 can be not only an ethylene gas detection sensor, but also a combination of an ethylene gas detection sensor and a micro camera or other sensors, which can not only detect whether the goods are rotten but also detect other conditions of the goods, such as temperature and humidity sensors, etc., which is more suitable for cold and fresh goods such as flowers or red wine.

[0033] See also Figure 4-Figure 7 The first and second side gears 303 and 306 are connected to each other through the upper and lower ends of the gear 304, and the lower ends of the gear 304 are connected to the upper and lower ends of the gear 304.

[0034] In this embodiment, the pause component 3 is installed inside the mounting frame, and the mounting frame provides support for the pause component 3. The mounting frame is located on one side of the lifting block 213. The driving gear 302, the first side gear 303, the intermediate gear 304 and the second side gear 306 are all located inside the mounting frame for rotation, and the shaft between the first side gear 303 and the first shift block 307 passes through the mounting frame and extends to its outside. The first shift block 307 is located on the outside of the mounting frame. The shaft between the second side gear 306 and the second shift block 308 also passes through the mounting frame and extends to its outside. The second shift block 308 is located on the outside of the mounting frame. A back plate is connected to the outside of the mounting frame, and the back plate is located on the rear side of the transverse movement component 4.

[0035] Specifically, the pause component 3 includes a driving motor 301, and the output end of the driving motor 301 is connected to the driving gear 302, the rear side of the first side gear 303 is connected to the first through shaft 3031, and one end of the first through shaft 3031 is connected to the first rectangular block 3032, one side of the first rectangular block 3032 is connected to the first pin 3033, and the first pin 3033 is located inside the high-low groove 3051, the rear side of the second side gear 306 is connected to the second through shaft 3061, and one end of the second through shaft 3061 is connected to the second rectangular block 3062, one side of the second rectangular block 3062 is connected to the second pin 3063, and the second pin 3063 is located inside the high-low groove 3051, the high-low groove 3051 includes a high groove, a low groove and a slope, and the high groove and the low groove are connected by the slope.

[0036] In this embodiment, the first side gear 303 and the second side gear 306 rotate in different directions, which will drive the first shift block 307 and the second shift block 308 to rotate in different directions, and then the middle segment block 309 can be shifted to rotate forward or reverse, so that the transverse movement component 4 can be expanded or retracted. The rotation of the rotating roller 305 is to allow the high-low groove 3051 to limit the first side gear 303 and the second side gear 306 so that they are not located in the same vertical plane. The high groove and the low groove in the high-low groove 3051 can achieve the purpose of limiting the first shift block 307 and the second The shift blocks 308 will not be located on the same vertical plane, and thus only one shift block can contact the dividing block 309. In the attached figure, the dividing grooves 3091 in the dividing block 309 are drawn as four groups, so there will be four fixed points in the path of expansion or storage of the transverse movement component 4. However, the attached figure does not limit actual production needs. If the partition length of the shelf 1 is short, the dividing grooves 3091 can be set to three groups, so that the transverse movement component 4 will only have three stop points on the path of expansion or storage. To match this, the first shift block 307 and the second shift block 308 must also be changed accordingly.

[0037] Specifically, the first shift block 307 includes an arc block 3071 and a shift shaft 3072, and the number of the shift shaft 3072 and the arc block 3071 are both two groups. The two groups of arc blocks 3071 and the shift shaft 3072 are symmetrically distributed, and a short pin shaft is provided at the end of the shift shaft 3072. The first shift block 307 has the same structure as the second shift block 308. There are multiple groups of dividing grooves 3091 equidistantly provided inside the dividing block 309, and the dividing grooves 3091 match the short pin shafts, and recessed arc blocks are provided between the multiple groups of dividing grooves 3091. The recessed arc blocks match the arc blocks 3071. A center axis is provided at the middle position of the dividing block 309, and the center axis is located on one side of the end gear 401.

[0038] In this embodiment, a worm gear set can be set between the central axis set at the middle position of the dividing block 309 and the end gear 401, so as to achieve the purpose of preventing the end gear 401 from reversing. In this way, when the end gear 401 stops rotating, even if it is affected by gravity, the dividing block 309 will not be reversed. The end gear 401, the first intermediate gear 407 and the second intermediate gear 408 can also use gears with large friction, and the friction force is sufficient to withstand the gravity of the detection component 5, which can also achieve the purpose of preventing reversal. In addition, there is a certain diameter ratio between the central axis and the end gear 401. The dividing block 309 rotates 360 degrees and the end gear 401 will rotate 90 degrees. The thickness of the central axis and the size of the end gear 401 in the accompanying drawings do not limit the actual ratio.

[0039] When in use, it is necessary to connect an external power supply, which provides electrical energy for the device so that the device can operate normally. First, the lifting motor 201 is started, and the lifting motor 201 drives the protrusion 202 to rotate. When the protrusion 202 rotates, it drives the hinged tooth plate 209 to move, and the hinged tooth plate 209 drives the screw gear 210 meshing with it to rotate. At the same time, during the rotation of the protrusion 202, since the side surface in contact with the roller 203 has a periodic undulating profile and a concave and convex surface, the conical plate 204 as a whole will rotate around the fixed point in the positioning block 205. When the roller 203 contacts the convex surface, the roller 203 is lifted up, and the end of the conical plate 204 away from the roller 203 drops, so it drives the bottom plate 206 to drop as a whole, and the bottom plate 206 drives the limit block 20 7 descends, and cooperates with the movement of the hinged tooth plate 209 to allow the screw gear 210 to rotate smoothly. When the protrusion 202 continues to rotate until the concave surface contacts the roller 203, the conical plate 204 will drive the bottom plate 206 to rise. At this time, the locking block 208 will be stuck in the tooth gap of the screw gear 210, and the upward limit block 207 will drive the hinged tooth plate 209 to move up as a whole and disengage from the screw gear 210. Therefore, the screw gear 210 will not rotate at this time. The rotation of the screw gear 210 will drive the screw 212 to rotate, which will drive the lifting block 213 to rise and fall. The stopped screw gear 210 will stop the lifting block 213 from rising and falling. At this time, the lifting block 213 is located on one side of the partition, and stopping the lifting is convenient for detecting the goods on the partition. After reaching one side of the target partition, the driving motor 301 is started, and the driving motor 301 drives the driving gear 302 to rotate, and the driving gear 302 drives the first side gear 303 to rotate, and the first side gear 303 drives the first shift block 307 to rotate. At the same time, the driving gear 302 also drives the intermediate gear 304 to rotate, and the intermediate gear 304 drives the second side gear 306 to rotate through meshing, and the second side gear 306 drives the second shift block 308 to rotate. When the intermediate gear 304 rotates, the rear rotating roller 305 rotates accordingly, and the first pin shaft 3033 and the second pin shaft 3063 The first shift block 307 and the second shift block 308 are respectively located in the high groove and the low groove of the high-low groove 3051, so that the first shift block 307 and the second shift block 308 in the front do not rotate in the same vertical plane. As a result, when the first shift block 307 rotates the dividing block 309, the second shift block 308 has no influence. Conversely, when the second shift block 308 rotates the dividing block 309, the first shift block 307 has no influence. The rotation of the dividing block 309 by the first shift block 307 is achieved by the contact between the short pin on the shift shaft 3072 and the dividing groove 3091, so the dividing block 309 forms an intermittent rotation motion process. The rotational action output from the dividing block 309 drives the end gear 401 to rotate, and the end gear 401 drives the first long shaft 402 and the first intermediate gear 407 to rotate, so that the back plate 406 is displaced. With the cooperation of the positioning short shaft 403 and the second long shaft 404, the first intermediate gear 407 rotates while also revolving around the end gear 401, and the rotation of the first intermediate gear 407 also drives the second intermediate gear 408 to rotate, thereby driving the third long shaft 409 to rotate. With the cooperation of the second intermediate short shaft 410 and the fourth long shaft 411, the tail short shaft 412 moves, and the tail short shaft 412 drives the detection component 5 to move. Because the dividing block 309 serving as the power rotates intermittently, the tail The short shaft 412 will drive the detection component 5 to stop at a fixed point. When it stops, the moving motor 501 can be started, so that the moving motor 501 drives the hinge shaft 502 to rotate, and the hinge shaft 502 drives the inner gear 503 to move on the inner side of the outer gear ring 504. Because of the meshing relationship, the inner gear 503 will rotate while moving, and the displacement shaft 505 will act on the detection head 506, which will cause the detection head 506 to move in a rectangular manner. The rectangular moving detection head 506 detects the odor leaking from the side seams of the goods to determine whether the goods are rotten. If there is no tail short shaft 412 to continue moving, it will drive the detection component 5 to continue to inspect the next part of the goods until the transverse movement component 4 is fully expanded. The inspection of this layer of goods is completed, and the inspection of the lower layer of goods continues.

[0040] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the present application. The scope of this application is defined by the appended claims and their equivalents.
