[0062] The sample storage chamber 10 comprises a storage rack 101, multiple storage layers arranged on the storage rack 101, each storage layer being provided with multiple trays 102 and reserving a tray accommodation space for the movement and cooperation between the trays. Each tray 102 is in a long strip shape and is provided with multiple positioning grooves 1021 at equal intervals, the positioning grooves 1021 being hollow grooves adapted to the size of the sample storage tank 200 for placing the sample storage tank 200 and stabilizing it to prevent it from being easily tilted; the positioning groove 1021 is provided with a groove sensing piece 10211; the groove sensing piece 10211 is electrically connected with the controller. Each positioning groove 1021 is provided with corresponding groove numbers and groove information, which are stored in the controller. The groove numbers can be sequentially arranged as No. 1, No. 2, No. 3, …, No. N, and the groove information can be the position information corresponding to the groove number in the space of the sample storage chamber 10, such as the groove information of a certain positioning groove 1021 being No. n, the groove number of the layer, the row and the groove. The front part of the sample storage chamber 10 (the side of the sample storage chamber 10 facing the user is the front part) is provided with a sample access window 103, and the inner side of the sample access window 103 has a positioning groove 1021 for placing a sample storage tank 200, and the sample storage tank 200 can be placed or taken out through the sample access window 103.

[0063] The other side of the sample storage chamber 10 (any side without a sample access window) is provided with a maintenance door and an alarm device. The maintenance door is usually in a closed state and can be locked by a door lock, which needs to be unlocked and opened by a corresponding key. In addition, the maintenance door is also provided with an opening sensor, and if the maintenance door is opened without reason, an abnormal opening signal is immediately generated and transmitted to the controller, and the alarm device is controlled by the controller to realize abnormal opening alarm. Only when the opening command is input to the controller of the sample storage chamber 10 under special or emergency circumstances, the maintenance door is allowed to be opened and will not trigger the alarm.

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

[0065] The operation machine 30 is arranged outside the sample storage room 10 and in front of the sample access window 103, and is used for storing and taking out samples.

[0066] The interactive component 40 is arranged on the operation machine 30 and is used for realizing human-computer interaction. The interactive component 40 can include function buttons, control knobs, a display screen, a broadcast component, and the like, and is used for realizing corresponding control, management, query, and the like by interacting with the user. The display screen can be a touch screen or a non-touch screen. When storing samples, the operator can input information such as the source of the stored coal sample, the test data, the storage weight, the storage time, and the storage purpose of the sample through the interactive component 40, and display the information on the display screen for the user to confirm. Optionally, a camera can be arranged on the display screen, and is used for taking photos of the sample storage person and the sample taking person, which is helpful for realizing monitoring and management.

[0067] As shown in Figure 3 , Figure 4 The sample storage tank 200 includes a tank body 2001, a sealing cover 2008, and a microprocessor, a communication circuit, a memory, and a rechargeable battery arranged in the tank body 2001. Each tank body 2001 is provided with a corresponding tank body identification code, which is a unique special number or name used to distinguish the tank body 2001. The tank body 2001 is a cylinder, and the sample inlet is arranged above the cylinder and is used for placing a quantitative coal sample, i.e., a coal sample with a preset weight or a preset volume. The height of the tank body 2001 can be set to different levels of short, medium, and long according to the storage requirement. The tank body 2001 is provided with a tank body sensing piece 2003 electrically connected with the microprocessor; the tank body sensing piece 2003 is used for being attracted to the slot sensing piece 10211 to fix the tank body 2001 and realize electrical connection between the controller and the microprocessor. After the controller and the microprocessor are electrically connected, the tank body identification code stored in the tank body 2001 can be read, the rechargeable battery in the tank body 2001 can be charged, and the microprocessor in the tank body 2001 can be communicated and controlled. Optionally, the tank body 2001 is made of a heat preservation material to cope with temperature difference changes in the case of power failure of the system, environmental transfer of the sample storage tank 200, and the like, so as to avoid that the internal coal sample is affected by the drastic temperature difference change. The sealing cover 2008 is used for closing the storage space in the tank.

[0068] When storing the sample, the controller receives the sample type to be stored input by the user through the interactive component 40, and determines the positioning groove 1021 based on the sample type to be stored, controls the grabbing mechanism 201 to pick up the sample storage tank 200 placed from the sample access window 103, and transfers to the positioning groove 1021; the controller is electrically connected with the microprocessor through the groove sensing part 10211 and the tank body 2001 sensing part, reads the tank body identification code corresponding to the tank body 2001 stored in the tank body 2001, records the storage time, and stores the sample type, the tank body identification code, the storage time, and the groove information one by one, to form a management database.

[0069] When sampling, the controller receives the sample type to be sampled input by the user through the interactive component 40, and determines the corresponding positioning groove 1021 based on the sample type to be sampled and the groove information, controls the grabbing mechanism 201 to pick up the sample storage tank 200 based on the groove information, and transfers the sample storage tank 200 to the positioning groove 1021 at the sample access window 103, so that the operator can remove the sample storage tank 200 from the sample storage chamber 10 through the sample access window 103. At this time, the controller records the sampling time and updates the management database.

[0070] After the sample storage tank 200 is placed in the corresponding positioning groove 1021, the sample administrator can set the corresponding supervision level through the controller, or set the supervision level after storing the sample by the corresponding personnel of the highest supervision level. The sample can be taken out only after the corresponding supervision level is approved. For example, if three levels of supervision are set, the coal sample of the first level of supervision can be taken out only with the authorization of the department level, the coal sample of the second level of supervision can be taken out only with the authorization of the factory level, and the coal sample of the third level of supervision can be taken out only with the authorization of the department level, the factory level, and the government supervision department.

[0071] Optionally, the operation machine 30 is further provided with a weighing component electrically connected with the controller. Before sampling, the operator places the sample storage tank 200 on the weighing component, inputs the sample type through the interactive component 40, and the weighing component transmits the weight information to the controller, so that the controller stores the sample type and the weight information correspondingly, to effectively manage the sample weight information. In addition, if the storage weight is not enough, a prompt information such as “the sample storage is not up to standard, please reload the sample” is popped up and prompted. Further, when sampling or querying the sample, the user can input the sample type through the interactive component 40 to query the sample weight and other storage states.

[0072] In an optional embodiment, the sample storage chamber 10 is a cabinet, the side walls and the top of which are made of transparent material to facilitate observation of the storage condition inside the cabinet. The term "cabinet" is used for the convenience of specific description. In practice, the sample storage "cabinet" can be constructed by relying on the existing building space interface of the sample storage chamber 10 (such as the ceiling, floor, wall, etc.), by building vertical load-bearing structures (such as columns) and horizontal partition units (such as partitions) to form a closed space, and by adding the required moving rails, control mechanisms and other components to the upper part and the periphery. When storing the sample, open the sample inlet and outlet window 103, place the sample storage jar 200 tightly at the bottom of the sample storage chamber 10, and then control the grabbing mechanism 201 by the controller to transfer the sample storage jar 200 to the preset position. The sampling process is reversed.

[0073] Further, for samples that need to be stored regularly (such as daily check samples, monthly check samples, etc.), the user can set reminders and warnings in the coal-fired check sample storage management system for carbon emission control enterprises. For samples that are not placed in time on the same day, information reminders can be sent, and warning information will be sent for samples that are not placed beyond the period. Samples that are stored later will be recorded and reported to higher management levels.

[0074] In an optional embodiment, a video monitoring device (not shown in the figure) is also installed on the periphery of the sample storage chamber 10. Once the sample storage jar 200 leaves the positioning groove 1021 in a non-permitted state, the system starts to issue a warning and upload the corresponding information, and the video monitoring device timely takes a live photo of the cabinet at the current time point and uploads it to the management system, so that the corresponding management department can confirm the situation at the first time.

[0075] In an optional embodiment, the sample storage chamber 10 is also equipped with a temperature regulating component (not shown in the figure) and a temperature and humidity monitoring component (not shown in the figure) to monitor the environmental parameters around the cabinet in real time. When the parameters exceed the set range, a warning is sent to the corresponding management level. If the actual conditions permit, the management control module of the storage system can be linked to the temperature regulating component of the storage chamber to adjust and control the temperature and humidity in the sample storage chamber 10 in real time, which is helpful for the effective storage of coal-fired check samples.

[0076] In an optional embodiment, the coal-fired check sample storage management system for carbon emission control enterprises also includes a remote communication module (not shown in the figure). The controller communicates with external computers, cloud platforms, cloud servers, smart phones and other smart devices through the remote communication module to realize information exchange. The user can check the storage condition of the coal-fired check sample on the smart phone or computer through the software client or webpage, which is convenient for monitoring and management. Correspondingly, sampling authorization approval can also be realized through remote communication, for example, the sampler can input the sampling application in the on-site sample storage chamber or on the smart phone or computer, and the authorized person can perform sampling approval on the remote smart device.

[0077] The technical scheme of the embodiment of the application can realize quantitative sample storage, has good sealing performance to prevent the characteristic failure of the coal sample, and can realize automatic operation in the sample feeding and discharging process, and record the sample type, storage position and storage time by the controller to form a management database and realize the standardized and strict management of the coal sample.

[0078] As shown in Figure 1 、 Figure 2 , in order to enable the sample storage tank 200 to move flexibly in the sample storage chamber 10 and realize sample feeding and discharging of the sample storage tank 200 at any position, in an optional embodiment, the left and right sides of the top of the storage rack 101 are provided with guide sliding grooves 1011, the transfer assembly 20 includes a grabbing mechanism 201, an N-shaped frame 202 and a pulley 203; the N-shaped frame 202 includes a horizontal rod 2021 and vertical plates 2022 located on both sides of the horizontal rod 2021; the two ends of the horizontal rod 2021 are embedded in the guide sliding grooves 1011 and are installed in cooperation with the guide sliding grooves 1011 through the pulley 203 to realize the forward and backward movement of the N-shaped frame 202; the vertical plates 2022 are provided with lifting tracks 20221; the bottom of the vertical plates 2022 is provided with a driven pulley 2023 to assist movement to maintain the stability of the overall movement of the transfer assembly 20.

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

[0081] When the sample storage tank 200 is being filled or sampled, if the tray 102 is full in the sample storage chamber 10, the grabbing mechanism 201 cannot pick up the sample storage tank 200 at any position. In an optional embodiment, the following method can be used to achieve this.

[0082] The opposite two sides of each layer of the storage rack 101 are provided with slide rails 1012 for the movement of the tray 102, and the bottom of both ends of the tray 102 is provided with a sliding part. The tray 102 is installed in the slide rail 1012 through the sliding part, so as to realize the horizontal movement of the tray 102 on the slide rail 1012 and drive the movement of the sample storage tank 200 on the tray 102. On each layer of the storage rack, the number of tray positions is greater than the number of trays 102, so as to reserve tray accommodation empty positions for the movement coordination between the trays during sample storage and sampling.

[0083] When sample storage or sampling is needed, the controller determines the target positioning slot according to the sample information input by the user, controls and coordinates the displacement of the trays on each layer, and forms a continuous tray accommodation empty position above the vertical projection area of the target positioning slot, so as to provide a moving space for the grabbing mechanism 201. The sample information to be sampled includes one or more of the following information: sample type, tank body identification code, slot number, and slot information.

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

[0085] The coal samples are various, and the storage amount of each coal sample is different. Therefore, the sample storage tank 200 is set to different capacities to meet the comprehensive storage of various coal samples. There are two ways to set the sample storage tank 200 to different capacities. One is to set the tank body 2001 of the sample storage tank 200 to different sizes, and the height remains the same. The second is to set the tank body 2001 of the sample storage tank 200 to the same size, and the height is different. If the first way is adopted, the tank body 2001 of the sample storage tank 200 is set to different sizes, and the size of the positioning groove 1021, the tray 102, the grabbing mechanism 201, and the sample storage chamber 10 or the number of the positioning groove 1021 need to be changed to adapt. Obviously, this way is more troublesome and will cause trouble to the design of each component. Therefore, in a preferred embodiment, the second way is adopted. That is, the storage rack 101 is provided with a plurality of vertical sliding grooves in the vertical direction of the sample storage chamber 10. The two ends of the sliding rail 1012 are clamped in the vertical sliding groove and can move up and down in the vertical sliding groove, driving the tray 102 to move up and down to adjust the layer height to adapt to the storage of the sample storage tank 200 of different heights. The sample storage chamber 10 can be designed according to the space requirement in the chamber to realize individual customization installation, such as the number of storage layers, the number of trays in each storage layer, the number of positioning grooves of each tray, and the height between the upper and lower storage layers.

[0086] Optionally, the up and down movement of the sliding rail 1012 in the vertical sliding groove can be manually moved and locked, or can be automatically moved and locked by the controller. Preferably, if a certain type of sample is stored for the first time, the user can also input the sample type or the height of the sample storage tank 200 through the interactive component 40, and the controller adjusts the layer height according to the sample type and the height of the sample storage tank 200, so as to place the corresponding sample storage tank 200 and realize adaptive storage. In addition, each layer can store full water samples, analysis samples or reference samples according to the needs.

[0087] In order to realize the effective record of the sample storage tank 200, the slot sensing part 10211 is a first magnetic attraction coil, the tank body sensing part 2003 is a second magnetic attraction coil, and the two magnetic attraction coils can be electrically connected through physical contact or non-physical contact. The upper end of the tank body 2001 is provided with an annular flange 2002, and the second magnetic attraction coil is arranged on the side of the annular flange 2002 facing the bottom of the tank body 2001 and is electrically connected with the microprocessor. The size of the annular flange 2002 is adapted to the inner diameter of the positioning groove 1021, so as to stably place the sample storage tank 200. When the tank body 2001 is placed on the positioning groove 1021, the controller is electrically connected with the microprocessor through the first magnetic attraction coil and the second magnetic attraction coil, reads the tank body identification code stored on the microprocessor, records the corresponding storage time, and forms a management database in combination with the sample type input by the user; when the tank body 2001 is separated from the positioning groove 1021, the second magnetic attraction coil is disengaged from the first magnetic attraction coil, and the controller records the sampling time corresponding to the tank body identification code and the slot signal.

[0088] Due to the characteristics of the coal-fired sample, the coal-fired sample needs to be strictly sealed and stored. In combination with Figure 4 、 Figure 5 、 Figure 6 , the sample storage tank 200 further comprises a sealing cover 2008 made of silica gel material or wooden material. The sealing cover 2008 is provided with a first thread, and the inner wall of the tank body 2001 is provided with a second thread, and the first thread and the second thread are locked together to form a female and male thread. The sealing cover 2008 seals the tank body 2001 by being deeply inserted into the opening of the tank body 2001, and the sealing cover 2008 and the tank body 2001 are connected and tightened through the female and male thread 20081 to realize the first layer locking between the sealing cover 2008 and the tank body 2001. Further, in order to obtain better sealing effect, a sealing rubber ring is arranged at the connection between the sealing cover 2008 and the tank body 2001.

[0089] The outer wall of the sealing cover 2008 is provided with a plurality of wedge-shaped grooves 2009 along the circumference thereof. From the radial cross section of the sealing cover 2008, a first side wall is formed by extending from a first position of the outer wall of the sealing cover 2008 to the center thereof by a first preset depth, a second side wall is formed by extending from a second position of the outer wall of the sealing cover 2008 to the center thereof by a second preset depth, the first side wall and the second side wall intersect to form a triangular notch, the included angle between the first side wall and the second side wall is less than 90 degrees, the opening of the triangular notch is larger, and gradually decreases to the intersection of the two side walls in the direction of the center of the sealing cover 2008. The inner wall of the tank body 2001 is provided with a plurality of extendable wedge-shaped teeth 2004, the size of the wedge-shaped teeth 2004 is adapted to the wedge-shaped groove 2009, the wedge-shaped teeth 2004 are embedded in the wedge-shaped groove 2009, and the wedge-shaped teeth 2004 are embedded in the wedge-shaped groove 2009 to realize the relocking between the sealing cover 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; the wedge-shaped tooth 2004 is provided with a micro-motion spring 2005 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. This method involves adding an electronic lock to the mechanical structure lock. The electronic lock cannot be opened arbitrarily and requires authorization from the corresponding regulatory level, thereby further ensuring the security of the coal samples for inspection during storage, preventing unauthorized personnel from opening them, and avoiding sample misplacement or insufficient storage time.

[0095] In addition, when the sample is stored and taken, the tank 2001 communicates and controls with the controller through the data line interface, and the corresponding coal sample information is recorded, and the tank cover is locked or unlocked.

[0096] To facilitate the pickup of the sample storage tank 200, the top of the sealing cover 2008 is a magnetic surface, and the end of the grabbing mechanism 201 is a magnetic suction disc. When the grabbing mechanism 201 is lowered to the position of the sample storage tank 200 to be picked up, the sample storage tank 200 is sucked by the magnetic suction disc. After the effective locking structure of the sample storage tank 200 is set, the sample storage tank 200 can be conveniently transferred by suction, effectively avoiding the collision risk caused by the grabbing mechanism 201 touching the tank 2001 during the transfer of the sample storage tank 200, and improving the safety of the sample storage tank 200 during the transfer.

[0097] To prevent coal dust from contaminating the tank 2001 and facilitate sample replacement, the coal sample storage and management system for carbon emission control enterprises further comprises a sealing bag. The sealing bag is used to store and seal the coal sample, that is, after the coal sample is loaded into the sealing bag, it is loaded into the tank 2001 for locking and storage. To further ensure the sealed storage of the coal sample and effectively manage the sealing bag, an information tag is provided on the sealing bag. The information of the information tag includes: sealing bag number, sample type, sample weight, and sealing bag identification code. A code scanning component is provided on the operation table 30 and faces the user, which is used to scan the information tag to obtain the sample type and the sealing bag identification code. Through the sealing bag identification code and the tank identification code, double identification and confirmation records of the coal sample are formed. The sealing bag identification code can be a bar code or a two-dimensional code. The information on the sealing bag identification code is the sealing bag number. If the sealing bag identification code is printed in real time and attached to the sealing bag, the information on the sealing bag identification code can also include sample type, sample weight, and sample form.

[0098] To realize the standardized management of the coal sample and prevent the coal sample from being taken and placed randomly, the coal sample storage and management system for carbon emission control enterprises further comprises a user identity verification function.

[0099] Specifically, the user identity verification component is further provided on the outside of the sample storage chamber of the storage device 100. The user identity verification component comprises a fingerprint lock 50 provided on the operation table 30, which is used to collect the user's fingerprint. When the sample is stored or taken, the controller compares the real-time collected user's fingerprint with the pre-stored user's fingerprint to realize user identity verification. Alternatively, the user identity verification component comprises a face recognition module provided on the sample storage chamber 10. When the sample is stored or taken, the face recognition module collects the user's face information, and the controller compares the real-time collected face information with the pre-stored face information to realize user identity verification.

[0100] When the sample is stored, 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 supervision, second-level supervision, and third-level supervision, and the sample types of each level of supervision need to be approved by the corresponding management personnel; when sampling, the user needs to apply for sampling based on the sample type, and obtain the authorization approval of the corresponding regulatory level management personnel, and after obtaining the sampling authorization code, the sample storage tank is taken out from the storage device, and the sealed cover of the tank body is automatically unlocked to take out the sample.

[0101] Since each sample is provided with a corresponding regulatory level, a list of authorized personnel is provided on each regulatory level, and the fingerprint feature information or face feature information of each authorized personnel, when sampling, the fingerprint information comparison or face feature information comparison can be used to realize the unlocking.

[0102] In addition, when the sample is sent to a third party for inspection, the controller sends the sample storage tank information (number, storage type, storage time, etc.) and the exclusive tank opening code to the detection agency; after receiving the sample storage tank information, the detection agency checks whether the sample storage tank information matches, and opens the sample storage tank through the tank opening code to take out the sample for detection. Specifically, after the tank body is sent to the third party detection agency, the data interface connected to the bottom of the tank body is checked to see if the tank body information is consistent, and the tank body is opened through the tank opening code after the check is passed. Take out the sample for detection.

[0103] Based on the above structure, the coal-fired sample storage management system applied to the carbon emission control enterprise can realize the storage and retrieval of the coal-fired sample.

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

[0105] S11: The coal-fired sample to be saved is pretreated, and after being made into corresponding daily inspection samples / full water analysis samples, it is sealed into a sealed bag and a corresponding sealed bag label is attached.

[0106] S12: Place the empty sample storage tank on the operation platform, connect the communication data line to connect the sample storage tank and the controller, the controller identifies and records the tank body identification code, displays the storage and locking state of the tank body through the display screen, then operates the wedge-shaped teeth to retract into the inner wall of the tank body, and the locking state of the sealing cover is released. At this time, the operator can manually unscrew the sealing cover.

[0107] S13: Place the two-dimensional code of the sealed bag label at the scanning port of the sample storage chamber, scan and record the corresponding coal sample information, and form a matching record with the tank body identification code, at the same time, take a photo of the sample storage personnel and display it on the display screen, then the operator places the coal sample bag into the tank body and tightens the tank cover.

[0108] S14: After the tank cover is tightened, the operator can control the wedge teeth to extend and abut against the wedge-shaped groove of the sealing cover to achieve locking. At this time, the sealing cover cannot be rotated in the opening direction. If the tightening is not completed but the wedge teeth have been controlled to extend, the sealing cover can still be rotated in the closing direction due to the fault tolerance space designed between the wedge teeth and the wedge-shaped groove. When the display screen displays that the wedge teeth have extended, the operator can slightly rotate in the tightening direction to make the wedge teeth well fit the wedge-shaped groove, thereby achieving the locking of the sealing cover and the tank body.

[0109] S15: After the sealing cover is locked, the display screen prompts that the sample storage tank can be placed. The operator places the tank body into the sample access window and controls the grabbing mechanism to move above the positioning groove at the sample access window. The grabbing mechanism sucks the sample storage tank and moves it to the corresponding positioning groove for placement. Then, the controller identifies the tank body code to ensure that the tank body is not placed incorrectly. If the tank body is placed incorrectly, a prompt will be given to re-place the sample storage tank.

[0110] S16: After the sample storage tank is correctly placed in the corresponding positioning groove, the layer, row, and column position coordinates of the tank body are recorded. The display screen prompts that the sample storage is complete. Subsequently, the sample storage information (sealing bag label information, sample type, coal sample weight, tank body identification code, storage position, etc.) is uploaded to the management system at various levels.

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

[0112] S21: Submit a sampling application for authorization and approval. The sampling application information includes one or more of the tank body identification code, groove position number, groove information, sealing bag identification code, sample storage time, sample type, sampling purpose, etc. The corresponding sampling voucher is generated and sent to the applicant's (the sampler's) system account. The sampling voucher is attached with a sampling two-dimensional code.

[0113] S22: The sampler prints a paper sampling voucher and places the sampling two-dimensional code at the scanning and sensing port of the sample storage room. If the two-dimensional code recognition is incorrect, a prompt "sampling information does not exist" will be given. At the same time, the video monitoring system captures the live footage of the personnel around the sample storage cabinet and uploads it to the management system at various levels. If the two-dimensional code recognition is incorrect for a certain number of times, an alarm message will be sent to the management system at various levels, and the video monitoring screen in this time period will be sent. At the same time, the sample storage cabinet system enters a locked state. After verification, the management system at various levels needs to be audited before it can be unlocked.

[0114] S23: After the sampling two-dimensional code is correctly recognized, the corresponding coal sample information and confirmation button are displayed on the display screen. The sampler clicks the confirmation button after confirming that there is no error. At the same time, the monitoring video captures the photo information of the sampler and uploads and saves it to the system together with other sampling information (sampling two-dimensional code, sampling time, sample number, etc.).

[0115] S24: The controller controls the movement of each layer tray according to the position of the sample storage tank to be taken out, to clear the sampling channel above the sample storage tank, then controls the grabbing mechanism to move to the corresponding position and lower to grab the sample storage tank, and then moves to the sample inlet and outlet window to place the sample storage tank.

[0116] S25: The sampler takes out the sample storage tank at the port, and if necessary, immediately unlocks the coal sample sealed bag, connects the tank body and the controller with the data line, inputs the unlocking information, controls the unlocking by the controller, and retracts the wedge teeth into the side wall of the tank body, at this time, the sealing cover can be unscrewed in the opening direction, and then the coal sample sealed bag is taken out.

[0117] The coal-fired sample storage management system based on the above structure applied to the carbon emission control enterprise can realize third-party inspection of the coal-fired sample.

[0118] The third-party inspection process can include the following steps:

[0119] S31: The system receives the third-party inspection application input by the user, and transmits the third-party inspection application to the detection agency, wherein the application information in the third-party inspection application includes one or more of the following information: sample storage tank identification code, slot number, sealed bag identification code, in addition, the application information can also include the storage time, storage type, and inspection purpose of the sample, after obtaining the corresponding level authorization approval, the corresponding sampling voucher is generated and sent to the applicant (sampler) system account, and the sampling voucher is attached with the tank sample two-dimensional code; at the same time, the sampling voucher and the third-party inspection application are sent to the detection agency.

[0120] S32: The same as S22-S24, after the sampler obtains the sample storage tank, the sample storage tank is sent to the detection agency by logistics or other means.

[0121] S33: After receiving the sample storage tank, the detection agency connects the sample storage tank and the detection agency through the data line, queries whether the sample information meets the application information of the previous inspection application, and opens the sample storage tank with the sample filling two-dimensional code to take out the coal sample sealed bag for detection.

[0122] The technical scheme of the embodiment of the application sets a sample storage tank specially used for storing coal-fired sample, which not only realizes quantitative sample storage, but also has good sealing property to prevent the characteristic failure of the coal-fired sample; sets a sample storage chamber specially used for placing the sample storage tank to obtain a stable sample storage environment and storage condition, realizes automatic operation in the sample inlet and outlet process, and records the sample type, sample storage position, and sample storage time by the controller to form a management database, realizes the standardized and strict management of the coal-fired sample, and ensures the authenticity and traceability of the third-party inspection sample, provides effective evidence for the carbon emission accounting.

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; 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. 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.

7. The coal sample storage and management system for carbon emission control enterprises as described in claim 6, characterized in that, The tank body is also equipped with a data transmission interface; The tank body is also provided with a moving part, which is electrically connected to the microprocessor and connected to the wedge-shaped teeth; 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.

8. The coal sample storage and management system for carbon emission control enterprises as described in claim 1, characterized in that, It also includes resealable bags and barcode scanning components; 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. 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.

9. The coal sample storage and management system for carbon emission control enterprises as described in claim 1, characterized in that, The outside of the sample storage room is also equipped with a user identity verification component. 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. And / or, 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.

10. The coal sample storage and management system for carbon emission control enterprises according to claim 1, characterized in that, 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; 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 storage container from the storage device based on the sampling authorization code. The sample can be taken out after the container's sealing cap is automatically unlocked. 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.
