Description

Technical Field

[0001] This application relates to the field of coal sample storage technology, and in particular to a coal sample storage and management system for carbon emission control enterprises. Background Technology

[0002] In the field of carbon emission control research, enterprises that are subject to carbon emission control need to keep coal samples, such as daily comprehensive coal samples, for several months for future reference, and monthly reduced coal samples for several years for future reference. In the detection of carbon content, enterprises need to keep coal samples consumed in each shift and each day of production, mix them in proportion to obtain monthly reduced samples, and send them to third-party technical institutions for testing. Therefore, the standardized and effective storage management of coal samples is a key link in the quality of carbon emission data.

[0003] Research revealed the following problems with the current storage conditions for coal samples for inspection: 1. Lack of standardized storage containers, making quantitative storage of samples impossible; 2. Inconsistent and rudimentary storage environments; 3. Lack of a standardized management system, resulting in unclear records of sample storage time, short storage periods, and arbitrary retrieval. Therefore, there is an urgent need to develop a coal sample storage management system for carbon emission control enterprises to address these issues. Summary of the Invention

[0004] To overcome the problems existing in related technologies, this application provides a coal sample storage and management system for carbon emission control enterprises. It can provide a stable and good storage environment for coal samples of carbon emission control enterprises, automatically realize storage and retrieval records, and achieve unified and effective management.

[0005] According to an embodiment of this application, a coal-fired sample storage and management system for carbon emission control enterprises is provided, comprising: a storage device and a sample storage tank;

[0006] The storage device includes: a controller, a sample storage chamber, a transfer component, and an interaction component;

[0007] The sample storage chamber includes: a storage rack, and multiple storage layers disposed on the storage rack. Each storage layer is provided with multiple tray positions and multiple trays. The tray positions are used to place the trays, and each tray is provided with multiple positioning slots. Each positioning slot is provided with corresponding slot information. A slot position sensor is provided on the positioning slot, and the slot position sensor is electrically connected to the controller. The front of the sample storage chamber is provided with a sample inlet / outlet window, and the inner side of the sample inlet / outlet window is provided with the positioning slot for placing the sample storage container.

[0008] The transfer assembly is mounted on the storage rack and has a gripping mechanism;

[0009] The interactive components are used to implement human-computer interaction;

[0010] The sample storage container includes a container body, a sealing cap, and a microprocessor disposed within the container body; the container body is used to hold a quantitative amount of coal samples for inspection, and each container body is equipped with a corresponding container identification code stored in the microprocessor; the container body is equipped with a container sensing element electrically connected to the microprocessor; the sealing cap is used to seal the storage space inside the container.

[0011] When storing a sample, the controller receives the type of sample to be stored from the user through the interactive component, determines the positioning slot based on the type of sample to be stored, and controls the gripping mechanism to pick up the storage container placed from the sample inlet / outlet window and transfer it to the positioning slot.

[0012] The controller is electrically connected to the microprocessor through the slot sensor and the tank sensor. It reads the tank identification code, records the storage time, and stores the sample type, the tank identification code, the storage time, and the slot information one by one to form a management database.

[0013] During sampling, the controller receives the sample type to be sampled from the user through the interactive component, and searches for the slot information based on the sample type. Based on the slot information, it controls the gripping mechanism to pick up the sample storage container and transfer it to the positioning slot at the sample entry / exit window. This allows the operator to move the sample storage container out of the sample storage room from the sample entry / exit window, and records the sampling time and updates the management database.

[0014] In an optional embodiment, guide grooves are provided on the left and right sides of the top of the storage rack, and the transfer assembly includes a U-shaped frame, a gripping mechanism, pulleys and driven pulleys;

[0015] The U-shaped frame includes a horizontal bar and vertical plates on both sides of the horizontal bar; the two ends of the horizontal bar are embedded in the guide groove and are installed in cooperation with the guide groove through pulleys to realize the forward and backward movement of the U-shaped frame; lifting rails are provided on the vertical plates on both sides; driven pulleys are provided at the bottom of the vertical plates on both sides to assist the movement and maintain the stability of the overall movement of the transfer component;

[0016] The gripping mechanism is installed on the U-shaped frame and is driven by the U-shaped frame to move back and forth. The gripping mechanism is installed in cooperation with the lifting rails of the vertical plates on both sides, attached to the U-shaped frame, and can move up and down in the vertical direction.

[0017] The length of the gripping mechanism is the same as the length of the tray; multiple gripping heads are installed below the gripping mechanism, and the number and position distribution of the gripping heads correspond to the positioning slots of the tray to realize the gripping of one or more sample containers; each gripping head is magnetically attracted and fixed to the sample container.

[0018] In an optional embodiment, each layer of the storage rack is provided with a slide rail for moving the tray; the bottom of both ends of the tray is provided with a sliding part, and the tray is installed by the sliding part cooperating with the slide rail, thereby realizing the movement of the tray on the slide rail; each layer of the storage rack is reserved with a tray accommodating space for the movement and cooperation between trays when storing and retrieving samples;

[0019] When it is necessary to store or retrieve a sample, the controller determines the target positioning slot based on the sample information input by the user, controls and coordinates the linkage displacement of each layer of trays, and forms a continuous tray accommodating space above the vertical projection area of ​​the target positioning slot, providing the gripping mechanism with activity space. The sample information to be retrieved is a tank identification code or slot information.

[0020] In an optional embodiment, the storage rack is provided with multiple vertical grooves in the vertical direction of the sample storage chamber. The two ends of the slide rail are engaged in the vertical grooves and can move up and down in the vertical grooves, thereby moving the tray up and down to adjust the layer height to accommodate the storage of sample tanks of different heights.

[0021] The sample storage room can be designed with different numbers of storage layers, the number of trays in each storage layer, the number of positioning slots in each tray, and the height between the upper and lower storage layers according to the indoor space requirements, so as to achieve personalized customized installation.

[0022] In an optional embodiment, the slot sensing element is a first magnetic coil, and the tank sensing element is a second magnetic coil.

[0023] The upper end of the tank is provided with an annular flange, and the second magnetic coil is provided on the side of the annular flange facing the bottom of the tank; the size of the annular flange is adapted to the inner diameter of the positioning groove.

[0024] When the tank is placed on the positioning slot, the controller is electrically connected to the microprocessor through the first magnetic coil and the second magnetic coil, and reads the tank identification code stored on the microprocessor;

[0025] When the tank body is detached from the positioning slot, the second magnetic coil is disengaged from the first magnetic coil, and the controller records the sampling time corresponding to the tank body identification code and the slot position signal.

[0026] In an optional embodiment, the sealing cap extends into the opening of the can to seal the can;

[0027] The sealing cap is screwed tightly onto the tank body via male and female threads.

[0028] The outer wall of the sealing cap is provided with multiple wedge-shaped grooves along its circumference; the inner wall of the can is provided with multiple retractable wedge-shaped teeth, the size of which is adapted to the wedge-shaped grooves, and the wedge-shaped teeth can be embedded in the wedge-shaped grooves; the length of the wedge-shaped teeth along the axial direction of the can is less than the length of the grooves, so as to achieve fault-tolerant fit; the wedge-shaped teeth are provided with micro-motion springs along the radial direction of the can.

[0029] When the sealing cover rotates clockwise, the guide slope of the wedge-shaped groove applies a radial compressive force to the wedge-shaped teeth, thereby compressing the micro-motion spring to make room for rotation, allowing the sealing cover to continue rotating until the wedge-shaped teeth are dislodged;

[0030] When the sealing cap rotates counterclockwise by a certain angle, the compressed micro-spring releases its elasticity, pushing the wedge-shaped teeth to fully embed into the wedge-shaped groove; when the sealing cap twists counterclockwise, the vertical locking surface of the wedge-shaped teeth contacts the side wall of the wedge-shaped groove on the sealing cap, and only bears the circumferential shear force. The micro-spring is always in the extended state, keeping the wedge-shaped teeth fully engaged in the wedge-shaped groove, thereby preventing the sealing cap from rotating counterclockwise, forming a mechanical self-locking mechanism for the sample storage container.

[0031] When the wedge tooth is extended, the distance L1 between the tip of the wedge tooth and the central axis of the sealing cap is greater than the distance L2 between the male and female threads and the central axis of the sealing cap, so that the sealing cap can be inserted into the can and tightened when the wedge tooth is extended.

[0032] In an optional embodiment, the tank body is further provided with a data transmission interface;

[0033] The tank body is also provided with a moving part, which is electrically connected to the microprocessor and connected to the wedge-shaped teeth;

[0034] When the tank is electrically connected to the controller through the data transmission interface, the controller receives an opening signal or a locking signal input by the user through the interactive component and transmits it to the microprocessor; the microprocessor controls the moving part to move back and forth along the radial direction of the tank to push the wedge teeth to extend or retract and engage with the wedge groove on the inner wall of the tank, thereby controlling the locking and opening between the sealing cap and the tank.

[0035] In an optional embodiment, a sealing bag and a barcode scanning component are also included;

[0036] The sealed bag is used to hold and seal the coal sample for inspection. The sealed bag is provided with an information label. The information label includes at least the following information: sealed bag identification code and sample type.

[0037] The scanning component is used to scan the information label to obtain the sample type and the sealed bag identification code, and to form a dual identification and confirmation of the sample for inspection through the sealed bag identification code and the can identification code.

[0038] In an optional embodiment, a user identity verification component is also provided outside the sample storage room.

[0039] The user identity verification component includes a fingerprint lock, which is used to collect user fingerprints. During sampling, the controller compares the real-time collected user fingerprints with the pre-stored user fingerprints to achieve user identity verification.

[0040] And / or,

[0041] The user identity verification component includes a face recognition module, which is used to collect user face information. During sampling, the controller compares the real-time collected face information with the pre-stored face information to realize user identity verification.

[0042] In an optional embodiment, when storing samples, the controller receives the regulatory level corresponding to the sample type set by the user through the interactive component and stores it in the management database; wherein, the regulatory level includes first-level regulation, second-level regulation, and third-level regulation, and the sample type of each level of regulation requires the corresponding management personnel to conduct sampling approval;

[0043] When taking samples, users need to submit a sampling application based on the sample type and obtain authorization and approval from the corresponding regulatory level management personnel. After obtaining the sampling authorization code, the user can then take the sample container out of the storage device based on the sampling authorization code. The sample can be taken out after the container's sealing cap is automatically unlocked.

[0044] When a sample is submitted for third-party testing, the controller sends the information of the storage tank to be sampled and the unique opening verification code to the testing institution. After receiving the storage tank information, the testing institution checks whether the storage tank information matches and opens the storage tank through the opening verification code to take out the sample for testing.

[0045] The technical solution of this application embodiment, by setting up a dedicated sample storage tank for storing coal samples for inspection, not only achieves quantitative sample storage but also has good sealing performance to prevent the coal samples from losing their characteristics; by setting up a dedicated sample storage room for placing the sample storage tank, a stable sample storage environment and storage conditions are obtained, and the process of sample injection and retrieval can be automated. The controller effectively records the sample type, sample storage location, and sample storage time to form a management database, thereby achieving standardized and strict management of coal samples for inspection.

Detailed Implementation

[0056] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0057] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0058] Currently, there is no unified and effective management method for the storage of coal samples for carbon emission control enterprises. Therefore, this application provides a coal sample storage management system for carbon emission control enterprises. This system is used for the sealed storage and management of coal samples for carbon emission control enterprises. It enables unified quantitative sealed storage of coal samples, ensuring the quality of the stored coal samples and maintaining their characteristics. It also achieves standardized and strict management of effective storage of coal samples, while ensuring the authenticity and traceability of samples sent to third-party testing, providing effective evidence for carbon emission accounting.

[0059] like Figure 1 , Figure 2 As shown, the coal sample storage and management system applied to enterprises subject to carbon emission control includes a storage device 100 and a sample storage tank 200.

[0060] The storage device 100 includes: a controller (not shown), a sample storage chamber 10, a transfer assembly 20, an operating platform 30, and an interaction assembly 40.

[0061] The controller serves as the control center for the coal sample storage and management system used by enterprises subject to carbon emission control. It is responsible for the operation and control of various components and for the effective storage and unified management of coal samples. The controller can be a control chip, microprocessor, tablet, mobile phone, smart computer, etc., and the specific form is not limited, as long as it can realize system control and management functions.

[0062] The sample storage chamber 10 includes: a storage rack 101 and multiple storage layers disposed on the storage rack 101. Each storage layer is provided with multiple trays 102, and a tray accommodating space is reserved to allow for movement and coordination between the trays. Each tray 102 is elongated, and each tray 102 has multiple equally spaced positioning slots 1021. Each positioning slot 1021 is a hollow slot adapted to the size of the container 2001, used to place the sample storage container 200 and stabilize it to prevent tipping. A slot position sensor 10211 is disposed on each positioning slot 1021; the slot position sensor 10211 is electrically connected to a controller. Each positioning slot 1021 is assigned a corresponding slot number and slot information, which are stored in the controller. The slot numbers can be sequentially arranged as 1, 2, 3...N. The slot information can be the location information within the sample storage chamber 10 corresponding to the slot number, such as the slot information of a certain positioning slot 1021 being number n, indicating which layer, row, and slot. The front of the sample storage chamber 10 (the side of the sample storage chamber 10 facing the user) is provided with an inlet / outlet window 103. Inside the inlet / outlet window 103 is a positioning slot 1021 for placing the sample storage tank 200. The sample storage tank 200 can be placed or removed through the inlet / outlet window 103.

[0063] On the other side of sample storage chamber 10 (any side without sample entry / exit windows), there is an inspection door and an alarm device. The inspection door is normally closed and can be locked with a door lock, requiring a corresponding key to unlock and open. Additionally, the inspection door is equipped with an opening sensor; if the inspection door is opened without cause, an abnormal opening signal is immediately generated and transmitted to the controller, which then activates the alarm device to trigger an abnormal door opening alarm. The inspection door is only allowed to open without triggering an alarm when an opening command is input to the controller of sample storage chamber 10 in special or emergency situations.

[0064] The transfer assembly 20 is installed on the top of the storage rack 101 and has a gripping mechanism 201; the controller controls the gripping mechanism 201 to pass through the tray receiving space, pick up the sample container 200 on the positioning slot 1021 and realize the transfer in three-dimensional space.

[0065] The operating platform 30 is located outside the sample storage chamber 10 and in front of the sample inlet / outlet window 103. The operating platform 30 is used to perform sample storage and retrieval operations.

[0066] An interactive component 40 is mounted on the operating platform 30 to enable human-machine interaction. The interactive component 40 may include function buttons, control knobs, a display screen, and a broadcast component, etc., for human-machine interaction with the user to achieve corresponding control, management, and query functions. The display screen can be a touchscreen or a non-touchscreen. When storing samples, the operator can input information such as the source, test data, sample weight, storage time, and storage purpose of the stored coal sample through the interactive component 40, which will be displayed on the screen for user confirmation. Optionally, a camera can also be installed on the display screen to take photos of the person storing and taking the sample, facilitating monitoring and management.

[0067] like Figure 3 , Figure 4 As shown, the sample storage container 200 includes a container body 2001, a sealing cap 2008, and a microprocessor, communication circuit, memory, and rechargeable battery disposed within the container body 2001. Each container 2001 is equipped with a corresponding container identification code, which is a unique number or name used to distinguish the container 2001. The container body 2001 is cylindrical, with the sample inlet located at the top of the cylinder, used to hold a quantitative amount of coal for testing, i.e., to hold a coal sample of a preset weight or volume. The height of the container body 2001 can be set to short, medium, or long levels according to storage requirements. A container sensor 2003 electrically connected to the microprocessor is provided on the container body 2001; the container sensor 2003 is used to attract each other with the slot position sensor 10211 to fix the container body 2001 and to realize the electrical connection between the controller and the microprocessor. After the controller is electrically connected to the microprocessor, it can read the tank identification code stored in tank 2001, charge the rechargeable battery inside tank 2001, and communicate and control with the microprocessor inside tank 2001. Optionally, tank 2001 is made of insulation material to cope with temperature changes in situations such as system power failure and environmental transfer of sample storage tank 200, so as to prevent drastic temperature changes from affecting the internal coal sample. Sealing cover 2008 is used to seal the internal storage space of the tank.

[0068] When storing samples, the controller receives the sample type to be stored from the user through the interactive component 40, and determines the positioning slot 1021 based on the sample type. It then controls the gripping mechanism 201 to pick up the storage container 200 placed from the sample inlet / outlet window 103 and transfer it to the positioning slot 1021. The controller is electrically connected to the microprocessor through the slot position sensor 10211 and the container body sensor 2001. It reads the container identification code corresponding to the container body 2001 stored in the container body 2001, records the storage time, and stores the sample type, container identification code, storage time, and slot position information one by one to form a management database.

[0069] During sampling, the controller receives the sample type to be sampled from the user through the interactive component 40, and finds the slot information based on the sample type to determine the corresponding positioning slot 1021. Based on the slot information, the controller controls the gripping mechanism 201 to pick up the sample storage tank 200 and transfer the sample storage tank 200 to the positioning slot 1021 at the sample entry / exit window 103, so that the operator can move the sample storage tank 200 out of the sample storage room 10 from the sample entry / exit window 103. At this time, the controller records the sampling time and updates the management database.

[0070] After the sample storage container 200 is placed into the corresponding positioning slot 1021, the sample administrator can set the regulatory level corresponding to the sample type through the controller, or the regulatory level can be set by the personnel at the highest regulatory level after the sample is stored. Sampling requires approval from the corresponding regulatory level before it can be retrieved. For example, with a three-level regulatory system, coal samples under Level 1 regulation only require departmental authorization, Level 2 requires plant-level authorization, and Level 3 requires authorization from the department, plant, and government regulatory authorities.

[0071] Optionally, the operating platform 30 is also equipped with a weighing component, which is electrically connected to the controller. Before sample loading, the operator places the sample storage container 200 on the weighing component and inputs the sample type through the interactive component 40. The weighing component acquires the weight information and transmits it to the controller, which stores the sample type and weight information accordingly, thereby achieving effective management of sample weight information. Furthermore, if the stored weight is insufficient, a prompt will appear on the display screen, such as "Sample storage is insufficient, please reload the sample." Further, when taking or querying samples, the user can input the sample type through the interactive component 40 to query the sample weight and other storage status.

[0072] In an optional embodiment, the sample storage chamber 10 is a cabinet, with its sides and top made of transparent material to facilitate observation of the storage conditions inside. The term "cabinet" is used for ease of description. In practice, the existing architectural space of the sample storage chamber 10 (such as ceiling, floor, walls, etc.) can be utilized to form an enclosed space by constructing vertical load-bearing structures (such as columns) and horizontal partition units (such as partitions). The necessary moving guide rails, control mechanisms, and other components are then added to the top and sides to complete the construction of the sample storage "cabinet." When storing samples, the sample inlet / outlet window 103 is opened, the sample storage container 200 is tightened and placed at the bottom of the sample storage chamber 10, and then the controller controls the gripping mechanism 201 to transfer the sample storage container 200 to a preset position. The sampling process is the reverse.

[0073] Furthermore, for samples that need to be stored regularly (such as daily sample storage and monthly sample reduction and storage), users can set reminders and warnings in the coal-fired sample storage management system applied to carbon emission control enterprises. For samples that are not placed on time on the same day, a reminder message can be sent. For samples that are not placed after the deadline, a warning message will be sent. Samples that are added afterward will be recorded and reported to higher-level management.

[0074] In an optional embodiment, a video surveillance system (not shown) is also installed around the sample storage chamber 10. If the sample storage tank 200 leaves the positioning slot 1021 without permission, the system will activate an early warning and upload relevant information. At the same time, the video surveillance will take a real-time photo of the cabinet and upload it to the management system so that the relevant management department can confirm the situation as soon as possible.

[0075] In an optional embodiment, the sample storage chamber 10 is also equipped with a temperature control component (not shown) and a temperature and humidity monitoring component (not shown) to monitor environmental parameters around the chamber in real time. When these parameters exceed the set range, an alert is sent to the corresponding management level. If actual conditions permit, the management control module of the storage system can be linked to the temperature control component of the storage chamber to adjust and control the temperature and humidity within the sample storage chamber 10 in real time, which helps to effectively store coal samples for inspection.

[0076] In an optional embodiment, the coal sample storage management system for carbon emission control enterprises also includes a remote communication module (not shown). The controller communicates with external computers, cloud platforms, cloud servers, smartphones and other smart devices through the remote communication module. Users can view the storage status of coal samples through software clients or web pages on their smartphones or computers, which facilitates monitoring and management. Correspondingly, sampling authorization and approval can also be achieved through remote communication. For example, the sampler can enter a sampling application in the on-site sample storage room or on a smartphone or computer, and the authorizer can approve the sampling on a remote smart device.

[0077] The technical solution of this application embodiment, by setting up a dedicated sample storage tank for storing coal samples for inspection, not only achieves quantitative sample storage but also has good sealing performance to prevent the coal samples from losing their characteristics; by setting up a dedicated sample storage room for placing the sample storage tank, a stable sample storage environment and storage conditions are obtained, and the process of sample injection and retrieval can be automated. The controller effectively records the sample type, sample storage location, and sample storage time to form a management database, thereby achieving standardized and strict management of coal samples for inspection.

[0078] like Figure 1 , Figure 2 As shown, in order to enable the sample storage tank 200 to move flexibly within the sample storage chamber 10 and to achieve sample injection and retrieval from the sample storage tank 200 at any position, in an optional embodiment, guide grooves 1011 are provided on the left and right sides of the top of the storage rack 101. The transfer assembly 20 includes a gripping mechanism 201, a U-shaped frame 202, and pulleys 203. The U-shaped frame 202 includes a horizontal bar 2021 and vertical plates 2022 located on both sides of the horizontal bar 2021. The two ends of the horizontal bar 2021 are embedded in the guide grooves 1011 and are installed in cooperation with the guide grooves 1011 through the pulleys 203 to realize the forward and backward movement of the U-shaped frame 202. Lifting rails 20221 are provided on the two vertical plates 2022. Driven pulleys 2023 are provided at the bottom of the two vertical plates 2022 to assist in movement and maintain the stability of the overall movement of the transfer assembly 20. The gripping mechanism 201 is installed on the U-shaped frame 202 and is driven by the U-shaped frame 202 to move back and forth. The gripping mechanism 201 is installed in conjunction with the lifting rails 20221 of the two side vertical plates 2022, attached to the U-shaped frame 202, and can move up and down in the vertical direction.

[0079] The length of the crossbar 2021 of the gripping mechanism 201 is the same as the length of the tray; multiple gripping heads 2012 are installed below the gripping mechanism 201, and the number and position distribution of the gripping heads 2012 correspond to the positioning slots of the tray to realize the gripping and movement of one or more sample containers; each gripping head adsorbs and fixes the sample container by magnetic attraction.

[0080] Optionally, the gripping mechanism 201 includes a mounting plate 2011 and a plurality of gripping heads 2012 located below the mounting plate 2011; the two ends of the mounting plate 2011 are embedded in the lifting rails 20221 of the two side vertical plates 2022, and can be controlled by the controller to slide up and down, thereby realizing the vertical movement of the gripping mechanism 201, thereby realizing the movement of the gripping heads 2012 at any position in three-dimensional space.

[0081] When the sample storage tank 200 is filled with samples, if the sample storage chamber 10 is full of trays 102, the gripping mechanism 201 will not be able to pick up the sample storage tank 200 at any position. In an optional embodiment, this can be achieved in the following way.

[0082] Each layer of the storage rack 101 has slide rails 1012 on two opposite sides for moving trays 102; sliding parts are provided at the bottom of both ends of the trays 102. The trays 102 are mounted in the slide rails 1012 via the sliding parts, thereby enabling the trays 102 to move horizontally on the slide rails 1012 and driving the sample storage containers 200 on the trays 102 to move; in each layer of the storage rack, the number of tray positions is greater than the number of trays 102, so as to reserve tray accommodating space for the movement and coordination between trays when storing and retrieving samples.

[0083] When samples need to be stored or retrieved, the controller determines the target positioning slot based on the sample information input by the user, and controls and coordinates the linkage displacement of each layer of trays to form a continuous tray accommodating space above the vertical projection area of ​​the target positioning slot, providing activity space for the gripping mechanism 201. The sample information includes one or more of the following: sample type, tank identification code, slot number, and slot information.

[0084] Optionally, the horizontal movement of the tray 102 on the same storage layer can be achieved by the controller controlling the corresponding transmission components, such as by pushing the tray 102 to move laterally by a motor, or by pulling the tray 102 to move laterally by a motor, as long as the movement of the tray 102 in the horizontal direction can be achieved.

[0085] Since there are various types of coal samples, the storage capacity for each type is different. Therefore, to meet the comprehensive storage needs of multiple coal samples, the sample storage tanks 200 are configured with different capacities. There are two ways to configure the sample storage tanks 200 with different capacities: one is to set the tank body 2001 of the sample storage tanks 200 to different sizes while maintaining a consistent height; the other is to set the tank body 2001 of the sample storage tanks 200 to a uniform size while varying the height. If the first method is adopted, setting the tank body 2001 of the sample storage tanks 200 to different sizes, the size of the positioning groove 1021, the tray 102, the gripping mechanism 201, and the sample storage chamber 10, or the number of positioning grooves 1021, all need to be changed to accommodate these variations. Obviously, this method is more cumbersome and will cause design problems for various components. Therefore, in a preferred embodiment, the second method is adopted. The storage rack 101 has multiple vertical grooves in the vertical direction of the sample storage chamber 10. The two ends of the slide rail 1012 are engaged in the vertical grooves and can move up and down within the vertical grooves, thereby moving the tray 102 up and down to adjust the layer height to accommodate sample storage tanks 200 of different heights. The sample storage chamber 10 can be designed with different numbers of storage layers, the number of trays in each storage layer, the number of positioning slots in each tray, and the height between upper and lower storage layers according to the indoor space requirements, to achieve personalized customized installation.

[0086] Optionally, the slide rail 1012 can be manually moved and locked within the vertical groove, or it can be automatically moved and locked by a controller. Preferably, if a certain type of sample is being stored for the first time, the user can input the sample type or the height of the storage tank 200 through the interactive component 40. The controller will then adjust the layer height according to the sample type and the height of the storage tank 200 to place the corresponding storage tank 200, achieving adaptive storage. In addition, each layer can store whole water samples, analytical samples, or reference samples as needed.

[0087] To achieve effective recording of sample intake and extraction from the sample storage tank 200, the slot position sensor 10211 is a first magnetic coil, and the tank body sensor 2003 is a second magnetic coil. The two magnetic coils can be electrically connected through physical contact or non-physical contact. An annular flange 2002 is provided at the upper end of the tank body 2001. The second magnetic coil is located on the side of the annular flange 2002 facing the bottom of the tank body 2001 and is electrically connected to the microprocessor. The dimensions of the annular flange 2002 are adapted to the inner diameter of the positioning slot 1021 to stably position the sample storage tank 200. When the container 2001 is placed on the positioning slot 1021, the controller is electrically connected to the microprocessor through the first magnetic coil and the second magnetic coil, reads the container identification code stored on the microprocessor, and records the corresponding storage time. Combined with the sample type input by the user, a management database is formed. When the container 2001 is removed from the positioning slot 1021, the second magnetic coil is disengaged from the first magnetic coil, and the controller records the sampling time corresponding to the container identification code and the slot position signal.

[0088] Due to the characteristics of the coal samples for inspection, they must be stored in a strictly sealed manner. Combined with... Figure 4 , Figure 5 , Figure 6 The sample storage container 200 also includes a sealing cap 2008, which is made of silicone or wood. The sealing cap 2008 has a first thread, and the inner wall of the container 2001 has a second thread. The first and second threads form a male-female thread that locks together. The sealing cap 2008 extends into the opening of the container 2001 to seal it. The sealing cap 2008 and the container 2001 are connected and tightened through the male-female thread 20081, achieving the first layer of locking between the sealing cap 2008 and the container 2001. Furthermore, to achieve a better sealing effect, a sealing rubber ring is provided at the connection between the sealing cap 2008 and the container 2001.

[0089] The outer wall of the sealing cap 2008 is provided with multiple wedge-shaped grooves 2009 along its circumference. Viewed radially from the outer wall of the sealing cap 2008, a first sidewall extends from a first point towards its center to form a first predetermined depth, and a second sidewall extends from a second point towards its center to form a second predetermined depth. The first and second sidewalls intersect to form a triangular notch. The included angle between the first and second sidewalls is less than 90 degrees. The opening of the triangular notch is relatively large, gradually narrowing towards the center of the sealing cap 2008 until the intersection of the two sidewalls. The inner wall of the tank body 2001 is provided with multiple retractable wedge-shaped teeth 2004. The size of the wedge-shaped teeth 2004 is adapted to the wedge-shaped grooves 2009. The wedge-shaped teeth 2004 are embedded in the wedge-shaped grooves 2009, achieving a re-locking between the sealing cap 2008 and the tank body 2001.

[0090] The length of the wedge-shaped tooth 2004 along the axial direction (height direction) of the tank body 2001 is less than the length of the wedge-shaped groove 2009, so as to achieve fault-tolerant fit; a micro-motion spring 2005 is provided on the wedge-shaped tooth 2004 along the radial direction of the tank body 2001.

[0091] When the sealing cover 2008 rotates clockwise, the guide slope of the wedge groove 2009 applies a radial compressive force to the wedge teeth, thereby compressing the micro spring 2005 to make room for rotation, so that the sealing cover 2008 can continue to rotate until the wedge teeth 2004 are released.

[0092] When the sealing cap 2008 rotates counterclockwise by a certain angle, the compressed micro-spring 2005 releases its elasticity, pushing the wedge-shaped tooth 2004 to fully embed into the wedge-shaped groove 2009; when the sealing cap 2008 twists counterclockwise, the vertical locking surface of the wedge-shaped tooth 2004 contacts the side wall of the wedge-shaped groove 2009 on the sealing cap 2008, and only bears the circumferential shear force. The micro-spring 2005 is always in the extended state, keeping the wedge-shaped tooth 2004 fully engaged in the wedge-shaped groove 2009, thereby preventing the sealing cap 2008 from rotating counterclockwise, forming a mechanical self-locking mechanism for the sample storage container.

[0093] like Figure 4 , Figure 5 As shown, the diameter of the end of the male and female thread 20081 is smaller than the diameter of the end of the groove of the wedge tooth 2004. That is, when the wedge tooth 2004 is in the extended state, the distance L1 between the tip of the wedge tooth 2004 and the central axis of the sealing cap 2008 is greater than the distance L2 between the male and female thread 20081 and the central axis of the sealing cap 2008, so that the sealing cap can be placed into the can and tightened when the wedge tooth 2004 is in the extended state.

[0094] To achieve automated opening and locking of the sample storage tank 200, a data transmission interface 2007 is also provided on the tank body 2001; a moving part 2006 is also provided inside the tank body 2001, which is electrically connected to the microprocessor and connected to the wedge teeth 2004; when the tank body 2001 is electrically connected to the controller through the data transmission interface 2007, the controller receives the opening signal or locking signal input by the user through the interactive component 40 and transmits it to the microprocessor; the microprocessor controls the moving part 2006 to move back and forth along the radial direction of the tank body 2001 to push the wedge teeth 2004 to extend or retract and engage with the wedge grooves 2009 on the inner wall of the tank, thereby controlling the locking and opening between the sealing cap 2008 and the tank body 2001. By adding an electronic lock to the mechanical structure lock, the electronic lock cannot be opened arbitrarily and requires authorization from the corresponding regulatory level. This further ensures the security of the coal samples for inspection during storage, prevents unauthorized personnel from opening the lock, and avoids sample misplacement or insufficient storage time.

[0095] In addition, during sample storage and retrieval, tank 2001 communicates and controls with the controller via a data cable interface to input relevant coal sample information and lock or unlock the tank cover.

[0096] To facilitate the pickup of the sample container 200, the top of the sealing cap 2008 is a magnetic surface, and the end of the gripping mechanism 201 is a magnetic suction cup. When the gripping mechanism 201 descends to the sample container 200 to be picked up, it picks up the sample container 200 through the magnetic suction cup. With an effective locking structure installed on the sample container 200, the sample container 200 can be transferred relatively easily by suction, effectively avoiding the risk of collision caused by the gripping mechanism 201 touching the container body 2001 during the transfer of the sample container 200, and improving the safety of the sample container 200 during transfer.

[0097] To prevent coal dust from contaminating the tank 2001 and to facilitate sample replacement, this coal sample storage management system for carbon emission control enterprises also includes sealed bags. The sealed bags are used to hold and seal the coal samples; after the samples are placed in the sealed bags, they are then placed inside the tank 2001 and locked for safekeeping. To further ensure the sealed storage and effective management of the coal samples, information labels are affixed to the sealed bags. The information on the labels includes: the sealed bag number, sample type, sample weight, and a sealed bag identification code. A barcode scanner is installed on the operating platform 30, facing the user, to scan the information labels and obtain the sample type and sealed bag identification code. The sealed bag identification code and the tank identification code form a dual identification and confirmation record for the samples. The sealed bag identification code can be a barcode or a QR code. The information on the sealed bag identification code is the sealed bag number. If the sealed bag identification code is printed and affixed to the sealed bag in real time, the information on the sealed bag identification code may also include sample type, sample weight, sample morphology, etc.

[0098] To achieve standardized management of coal samples for inspection and prevent arbitrary handling of these samples, the coal sample storage management system applied to carbon emission control enterprises also includes a user identity verification function.

[0099] Specifically, a user identity verification component is also installed outside the sample storage chamber of the storage device 100. The user identity verification component includes a fingerprint lock 50 installed on the operating table 30. The fingerprint lock 50 is used to collect the user's fingerprint. During sample storage and retrieval, the controller compares the real-time collected user fingerprint with the pre-stored user fingerprint to realize user identity verification; and / or, the user identity verification component includes a face recognition module installed on the sample storage chamber 10. During sample storage and retrieval, the face recognition module collects the user's face information. The controller compares the real-time collected face information with the pre-stored face information to realize user identity verification.

[0100] When storing samples, the controller receives the regulatory level corresponding to the sample type set by the user through the interactive component and stores it in the management database. The regulatory levels include Level 1, Level 2, and Level 3. Each level of regulation requires the corresponding management personnel to approve the sampling. When sampling, the user needs to submit a sampling application based on the sample type and obtain authorization approval from the management personnel at the corresponding regulatory level. After obtaining the sampling authorization code, the user can then retrieve the sample storage container from the storage device based on the sampling authorization code. The container's sealing cap will automatically unlock, and the sample can then be retrieved.

[0101] Since each sample is assigned a corresponding regulatory level, and each regulatory level has a list of authorized personnel, as well as the fingerprint or facial feature information of each authorized personnel, the lock can be unlocked by comparing the fingerprint or facial feature information during sampling.

[0102] In addition, when samples are submitted for third-party testing, the controller sends the information of the storage tank to be sampled (number, sample type, storage time, etc.) and a unique opening verification code to the testing institution. After receiving the storage tank information, the testing institution checks whether the storage tank information matches, and opens the storage tank using the opening verification code to retrieve the sample for testing. Specifically, after the tank is sent to the third-party testing institution, the data interface at the bottom of the tank is connected to check whether the tank information is consistent. If it is consistent, the tank is opened using the opening verification code to retrieve the sample for testing.

[0103] Based on the above structure, a coal sample storage and management system for enterprises subject to carbon emission control can be applied to realize the storage and retrieval of coal samples for inspection.

[0104] The sample storage process may include the following steps:

[0105] S11: Pre-process the coal samples to be stored for inspection, prepare them into corresponding daily inspection samples / total water analysis samples, put them into sealed bags, and affix the corresponding sealed bag labels.

[0106] S12: Place the empty sample storage container on the operating table, connect the sample storage container to the controller via the communication data cable, the controller identifies and records the container identification code, and displays the storage and locking status of the container on the display screen. Then, operate the control wedge teeth to retract into the inner wall of the container to release the locking status of the sealing cover. At this time, the operator can manually unscrew the sealing cover.

[0107] S13: Place the QR code on the sealed bag label into the scanning port of the sample storage room, scan and record the corresponding coal sample information, and form a pairing record with the tank identification code. At the same time, take a photo of the sample storage personnel and display it on the screen. Then, the operator puts the coal sample bag into the tank and tightens the tank lid.

[0108] S14: After the can lid is tightened, the operator can control the wedge teeth to extend and engage with the wedge groove of the sealing lid to lock it in place. At this time, the sealing lid can no longer be rotated in the opening direction. If it is not tightened but the wedge teeth have been extended, the sealing lid can still be rotated in the closing direction because of the fault-tolerant fit space designed between the wedge teeth and the wedge groove. When the display shows that the wedge teeth have extended, the operator can rotate it slightly in the tightening direction to make the wedge teeth fit well with the wedge groove, thereby locking the sealing lid and the can body.

[0109] S15: After the sealing cap is locked, the display screen indicates that the sample storage container can be placed. The operator places the container into the sample inlet / outlet window and controls the gripping mechanism to move above the positioning slot at the sample inlet / outlet window. The gripping mechanism picks up the sample storage container and transfers it to the corresponding positioning slot. Then the controller identifies the container code to ensure that the container is not placed incorrectly. If the container is placed incorrectly, the operator will be prompted to put the sample storage container back in.

[0110] S16: After the sample storage container is correctly placed into the corresponding positioning slot, record the layer, row, and column position coordinates of the container. The display screen will indicate that the sample storage is complete. Then, upload the sample storage information (sealed bag label information, sample type, coal sample weight, container identification code, storage location, etc.) to the management system at each level.

[0111] The sampling process may include the following steps:

[0112] S21: Submit a sampling application and obtain authorization approval. The sampling application information includes one or more of the following: tank identification code, slot number, slot information, sealed bag identification code, storage time, sample type, sampling purpose, etc. A corresponding sampling certificate is generated and sent to the applicant's (sampler's) system account. The sampling certificate includes a sampling QR code.

[0113] S22: The sampler prints a paper sampling certificate and places the sampling QR code on the scanning sensor port of the sample storage room. If the QR code is misidentified, a message will be displayed saying "Sampling information does not exist". At the same time, the video monitoring system will capture the real-time situation of the people around the sample storage cabinet and upload it to the management system at all levels. If the QR code is misidentified more than a certain number of times, an alarm message will be sent to the management system at all levels, and the video monitoring footage of that time period will be sent. At the same time, the sample storage cabinet system will enter a locked state. After verifying the situation, the management system at all levels must review and approve before it can be unlocked.

[0114] S23: After the sampling QR code is correctly recognized, the corresponding coal sample information and confirmation button are displayed on the screen. After the sampling personnel confirm that there is no error, they click to confirm. At the same time, the monitoring video captures the sampler's photo information and uploads it to the system along with other sampling information (sampling QR code, sampling time, sample number, etc.).

[0115] S24: The controller controls the movement of each layer of trays according to the location of the sample storage container to make room for sampling above the sample storage container. Then, the controller controls the gripping mechanism to move to the corresponding position and lower to grip the sample storage container. After that, it moves to the sample inlet / outlet window to place the sample storage container.

[0116] S25: The sampler takes out the sample storage tank at the port. If it is necessary to unlock and take out the coal sample sealed bag immediately, connect the tank and the controller with the data cable, input the unlocking information, and the controller will control the unlocking so that the wedge teeth retract into the side wall of the tank. At this time, the sealing cover can be unscrewed in the opening direction and the coal sample sealed bag can be taken out.

[0117] Based on the above structure, the coal sample storage and management system for enterprises subject to carbon emission control can realize third-party testing of coal samples.

[0118] The third-party testing process may include the following steps:

[0119] S31: The system receives a third-party testing application from the user and transmits it to the testing institution. The application information in the third-party testing application includes at least one or more of the following: storage tank identification code, tank number, and sealing bag identification code. In addition, the application information may also include the storage time of the sample, the storage type, and the purpose of the test. After obtaining the corresponding level of authorization and approval, a corresponding sampling certificate is generated and sent to the applicant's (sampler's) system account. The sampling certificate includes a tank sample QR code. At the same time, the sampling certificate and the third-party testing application are sent to the testing institution.

[0120] S32: Same as S22-S24, after obtaining the sample container, the sampler shall deliver the sample container to the testing agency via logistics or other means.

[0121] S33: After receiving the sample storage tank, the testing agency connects the sample storage tank and the testing agency via a data cable. The testing agency checks whether the sample information matches the application information in the previous submission application, and opens the sample storage tank with the sample filling QR code to take out the sealed coal sample bag for testing.

[0122] The technical solution of this application embodiment, by setting up a dedicated storage tank for storing coal samples for inspection, not only achieves quantitative sample storage but also has good sealing performance to prevent the coal samples from losing their characteristics. By setting up a dedicated storage room for the storage tank, a stable storage environment and conditions are obtained. The process of sample injection and retrieval can be automated. The controller effectively records the sample type, storage location, and storage time to form a management database, realizing standardized and strict management of coal samples for inspection. It also ensures the authenticity and traceability of samples submitted by third parties, providing effective evidence of samples for carbon emission accounting.
