Description

Technical Field

[0001] This invention relates to the field of coal sample testing, and in particular to a coal sample storage container and storage system. Background Technology

[0002] Coal sample storage devices are used to store coal samples. Existing coal sample storage devices mostly rely on built-in batteries for power or manual operation for the lid. Frequent battery charging or replacement not only increases maintenance costs but also risks the locking mechanism failing due to battery depletion, affecting the safety of coal sample storage. Furthermore, the locking pins often use sliding fit structures such as copper sleeves, resulting in high frictional resistance and poor sealing, allowing coal dust to easily enter the mechanism and cause jamming, shortening the equipment's lifespan. In addition, there is a lack of effective anti-tampering detection design; after the shell is disassembled, there is no self-locking protection mechanism, posing a risk of unauthorized tampering of coal samples during storage, compromising the authenticity of test data. Some lids use a dual-cylinder driven locking structure, with numerous components and a complex layout, increasing manufacturing difficulty and potentially affecting locking stability due to cylinder synchronization issues. Some lid-handling robotic arms have poor adaptability, lacking dedicated short-range communication modules, making automatic transmission and reception of locking commands and status feedback impossible, relying on manual intervention and resulting in low efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a coal sample storage container and storage system that effectively prevents the coal sample inside the container from being tampered with.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a coal sample storage container, comprising: a cylindrical body, one end of which has an opening, and a coal sample being loaded inside the cylindrical body; a lid, which is detachably connected to one end of the cylindrical body; a locking mechanism, which is connected to the lid and can fix the lid to the cylindrical body, wherein when the lid is fixed to the cylindrical body, the locking mechanism is located inside the cylindrical body; and a main control mechanism, which has a receiving end and a processing end, wherein the receiving end can receive control signals, and the processing end can respond to the control signals to control the working state of the locking mechanism.

[0005] Furthermore, the locking mechanism includes a housing and a telescopic unit. The housing is connected to the bucket lid. The housing has a through hole, and the cylinder has a locking hole corresponding to the through hole. When the telescopic unit is in the first working position, the output end of the telescopic unit can pass through the through hole and extend into the locking hole.

[0006] Furthermore, the locking mechanism also includes a steering wheel, which is connected to the input end of the telescopic unit. When the steering wheel rotates, it can drive the input end of the telescopic unit to move, and when the input end of the telescopic unit moves, it can drive the output end of the telescopic unit to move.

[0007] Furthermore, the telescopic unit includes a pin, a pull rod, and a linear bearing. The linear bearing is disposed in the through hole, and the pin is inserted into the linear bearing. One end of the pin is rotatably connected to one end of the pull rod, and the other end of the pull rod is rotatably connected to the rudder. The other end of the pin is the output end of the telescopic unit, and the other end of the pull rod is the input end of the telescopic unit.

[0008] Furthermore, the locking mechanism also includes a micro switch. The bucket lid is detachably connected to the housing via a fixing member. The micro switch is connected to the fixing member. When the fixing member moves, the micro switch can be triggered. The micro switch is connected to the main control mechanism.

[0009] Furthermore, the number of telescopic units is at least three, and each telescopic unit on the housing has a through hole, with the distance between adjacent through holes being the same.

[0010] Furthermore, the locking mechanism also includes a support plate and an unlocking / locking actuator. The support plate is disposed inside the housing and connected to the housing. The unlocking / locking actuator is disposed on the support plate. The output end of the unlocking / locking actuator is connected to the steering disk. The unlocking / locking actuator is configured to rotate the steering disk in response to the output signal of the main control mechanism.

[0011] Furthermore, the main control mechanism includes a main controller, a first infrared transceiver, and an infrared communication window. The main controller and the first infrared transceiver are located inside the housing. The main controller is connected to the first infrared transceiver. The infrared communication window is located on the lid of the bucket. The first infrared transceiver can transmit infrared signals through the infrared communication window.

[0012] Furthermore, the main control mechanism also includes a wireless charging coil, which is connected to the main controller.

[0013] On the other hand, a coal sample storage system is provided, including a robotic arm and the aforementioned storage container; the end of the robotic arm is provided with a pneumatic gripper, which can hold the container lid, and the pneumatic gripper is provided with a wireless control module, which can transmit control signals to the main control mechanism.

[0022] The accompanying drawings illustrate one or more examples of the invention. The detailed description uses numerals and letters to refer to features in the drawings. Similar or analogous reference numerals in the drawings and description have been used to refer to similar or analogous parts of the invention. As used herein, the terms “first,” “second,” “third,” and “fourth,” etc., are used interchangeably to distinguish one component from another and are not intended to indicate the location or importance of a single component.

[0023] like Figure 1 As shown, according to an embodiment of the present invention, a coal sample storage container is provided, comprising: A cylindrical body, with an opening at one end, is used to load coal samples inside the cylindrical body; a lid 1, which is detachably connected to one end of the cylindrical body; a locking mechanism, which is connected to the lid and can fix the lid 1 to the cylindrical body. When the lid 1 is fixed to the cylindrical body, the locking mechanism is located inside the cylindrical body; and a main control mechanism, which has a receiving end and a processing end. The receiving end can receive control signals, and the processing end can respond to the control signals to control the working state of the locking mechanism.

[0024] In one embodiment of this application, the cylinder is typically made of a metal material, such as stainless steel, and is preferably cylindrical in shape to facilitate even pressure distribution and easy cleaning. The open end is typically equipped with a precision-machined flange or threaded structure for precise mating with the lid 1. The lid 1 is a sealing component that mates with the cylinder. The locking mechanism moves with the lid 1. When the lid 1 is closed to a predetermined position on the cylinder, the locking mechanism performs a locking action. The main control mechanism controls the locking mechanism, thereby changing the connection state between the lid 1 and the cylinder.

[0025] like Figure 2 As shown, in one embodiment of this application, the locking mechanism includes a housing 2 and a telescopic unit. The housing 2 is connected to the bucket lid 1. The housing 2 is provided with a through hole, and the cylinder is provided with a locking hole corresponding to the through hole. When the telescopic unit is in the first working position, the output end of the telescopic unit can pass through the through hole and extend into the locking hole.

[0026] Specifically, the locking mechanism's locking action is a "telescopic insertion" mechanical locking action. The housing 2 serves as the skeleton and mounting base of the locking mechanism. It is securely fixed to the inside of the lid 1, facing the interior of the cylinder, using screws. The material of the housing 2 must possess sufficient structural strength and rigidity to withstand the reaction force during locking and possible external impacts. Through holes are machined into the side wall of the housing 2. The axial direction of the through holes determines the direction of the locking action. On the cylinder, in areas precisely corresponding to the preset positions of the through holes in the housing 2, a number of "locking holes" are provided, matching their positions. The "first working position" is the state when the telescopic unit performs the locking function. In this state, the output end of the telescopic unit generates an outward linear movement along its axial direction. This movement causes the output end to first penetrate the corresponding through hole on the housing 2, then continue forward, and finally precisely "extend" into the aligned locking hole in the cylinder. Once the output end is simultaneously located within both the through-hole of the housing 2 and the locking hole of the cylinder, it forms a mechanical barrier, preventing the lid 1 from separating from the cylinder. The unlocking process is the reverse: the output end retracts from the locking hole, fully returning to the through-hole of the housing 2, thereby disengaging the mechanical interlock and allowing the lid 1 to be removed. This structure offers high security. The junction between the output end and the locking hole is deeply concealed inside the container, making it invisible and inaccessible from the outside.

[0027] In one embodiment of this application, the locking mechanism further includes a rudder disk 3, which is connected to the input end of the telescopic unit. When the rudder disk 3 rotates, it can drive the input end of the telescopic unit to move. When the input end of the telescopic unit moves, it can drive the output end of the telescopic unit to move.

[0028] Specifically, the rudder disc 3 is a control component that allows the operator to apply rotational torque. Its shape is typically circular, polygonal, or a disc-like structure with a handle. In some applications, the rudder disc is designed to be completely concealed, allowing for disassembly and maintenance during troubleshooting. The core function of the rudder disc 3 is to establish a direct mechanical connection with the "input end" of the telescopic unit. Its working principle is based on the conversion and transmission of motion: when the rudder disc 3 rotates, its rotational motion is converted into the motion required by the input end through the connection structure between it and the input end of the telescopic unit.

[0029] In one embodiment of this application, the telescopic unit includes a pin 4, a pull rod 5, and a linear bearing 6. The linear bearing 6 is disposed in a through hole, and the pin 4 is inserted into the linear bearing 6. One end of the pin 4 is rotatably connected to one end of the pull rod 5, and the other end of the pull rod 5 is rotatably connected to the rudder disk 3. The other end of the pin 4 is the output end of the telescopic unit, and the other end of the pull rod 5 is the input end of the telescopic unit.

[0030] Specifically, the telescopic unit consists of three core mechanical components: pin 4, pull rod 5, and linear bearing 6. Pin 4 is the final locking actuator, i.e., the output end. The inner ring of linear bearing 6 provides a low-friction, high-precision linear motion channel. Linear bearing 6 is equipped with balls, converting sliding friction into rolling friction, significantly reducing resistance; a sealing rubber ring is added to the end of linear bearing 6 near the cylinder, forming a physical sealing barrier with pin 4 to prevent coal dust from entering the bearing. The rod portion of pin 4 is inserted into linear bearing 6, i.e., passing through the inner hole of linear bearing 6. The function of linear bearing 6 is to provide linear guidance for the telescopic movement of pin 4, greatly reducing frictional resistance and wobbling during movement, ensuring that pin 4 can move smoothly and steadily along its axis at all times, thereby ensuring accurate insertion into the locking hole each time locking occurs, avoiding locking failure or component damage due to jamming or tilting. Pull rod 5 is the transmission link connecting the drive of steering disc 3 and the movement of pin 4. One end of the rod 5 is connected to the tail end of the pin 4, i.e., the non-working end, via a "rotational connection." This rotational connection typically uses a pin shaft connection. The purpose is to allow the rod 5 to have a certain angle of movement with the pin 4 when transmitting push and pull forces. This is because the motion trajectory of the rod 5 is not coincident with the axis of the pin 4. It can be understood that when multiple rods 5 are connected to a rotating rudder disk 3, their motion is an arc around the center of the rudder disk 3. The rotational connection can compensate for this mismatch in motion trajectory, effectively converting the compound motion of the rod 5 into the pure axial motion of the pin 4, while avoiding harmful lateral forces that could cause the pin 4 to jam against the linear bearing 6. The other end of the rod 5 is connected to the rudder disk 3. The connection method depends on the specific mechanism of the rudder disk 3 that converts rotational motion into linear pulling. Another design involves one or more pin shafts on the surface of the rudder disk 3 at a position off-center, with the end of each rod 5 fitted onto these pin shafts via a sliding sleeve or a spherical bearing. When the steering wheel 3 rotates, these eccentric pins revolve around the center of the steering wheel 3, thereby pulling the connected rod 5 in a near-linear reciprocating motion. The reciprocating motion of the rod 5, through the rotating connection point at its other end, directly pushes or pulls the pin 4 within the linear bearing 6 for precise axial extension and retraction, achieving locking and unlocking. This embodiment features a simple structure, high transmission efficiency, and extremely high reliability. The linear bearing 6 ensures operational precision, and the entire mechanism is highly durable, making it ideal for applications in industrial environments requiring frequent and reliable operation.

[0031] In one embodiment of this application, the locking mechanism further includes a micro switch. The lid 1 is connected to the housing 2 via a fastener. The micro switch is connected to the fastener. When the fastener moves, it can trigger the micro switch to generate an anti-tamper signal. The micro switch is connected to the main control mechanism. The fastener can be a screw.

[0032] Specifically, a deeper layer of proactive monitoring and alarm security mechanism targeting unauthorized physical disassembly has been added, significantly enhancing the system's tamper-proof capabilities. The core of this mechanism lies in utilizing the mechanical connection between the lid 1 and the housing 2 as the monitoring target. Specifically, the lid 1 and housing 2 are not an inseparable, integral structure, but rather are securely connected via one or more "fixtures." This design facilitates production assembly, internal maintenance, and component replacement. These fixations firmly secure the housing 2 to the inner surface or frame of the lid 1. A microswitch is a small, sensitive mechanical-electronic switch containing a set of internal contacts and an external trigger lever. The microswitch is cleverly positioned at the connection interface between the lid 1 and housing 2, and its trigger mechanism is linked to one or more key connecting "fixtures." The linkage mechanism can be designed in various ways: for example, a special washer is pressed under the nut of the fastener, and this washer simultaneously contacts the trigger rod of the micro switch; or, the screwing position of the fastener directly determines the position of a linkage rod or pressure plate, which controls the triggering state of the micro switch. When all the fasteners are properly tightened to the preset torque, the pressure they exert on the micro switch triggering mechanism, or the position they hold, precisely puts the internal contacts of the micro switch in a preset stable state. The micro switch is electrically connected to the main control mechanism. When someone attempts to illegally open the container and chooses to bypass the main locking mechanism to directly remove the lid 1, their first step will inevitably be to loosen these connecting fasteners. Once the fasteners begin to loosen, the pressure or positional constraint they exert on the micro switch triggering mechanism changes immediately. This tiny mechanical displacement is enough to "trigger" the micro switch, causing its internal contact state to change instantaneously. This state change will immediately generate an electrical signal jump, which is instantly transmitted to the main control mechanism through the wire. Upon receiving the anti-tamper signal, the main control mechanism immediately controls the entire system to self-lock, preventing the locking mechanism from moving and prohibiting read / write operations. It needs to be returned to the factory and unlocked by inputting a dedicated infrared reset code through the infrared communication window 10. Normal function can only be restored after unlocking. Optional irregular-shaped fasteners can be added to further enhance the mechanical anti-tamper capability and avoid disassembly with conventional tools.

[0033] In one embodiment of this application, the number of telescopic units is at least three. Each telescopic unit on the housing 2 has a through hole, and the distance between adjacent through holes is the same. When the number of telescopic units is three, the included angle between adjacent telescopic units is 120°. The three telescopic units can ensure that the locking mechanism is subjected to more uniform force and extend its service life.

[0034] like Figure 3As shown, in one embodiment of this application, the locking mechanism further includes a support plate 11 and an unlocking / locking actuator 7. The support plate 11 is disposed inside the housing 2 and connected to the housing 2. The unlocking / locking actuator 7 is disposed on the support plate 11. The output end of the unlocking / locking actuator 7 is connected to the rudder disk 3. The unlocking / locking actuator 7 is configured to rotate the rudder disk 3 in response to the output signal of the main control mechanism.

[0035] Specifically, the support plate 11 is a robust plate-like structure connected to the inner wall of the housing 2 and fixed inside the housing 2. The main function of the support plate 11 is to provide a stable, flat, and reliable mounting surface for the "locking / unlocking actuator 7" and other possible electronic components, while also helping to organize the internal wiring harness and enhance the overall structural rigidity. The locking / unlocking actuator 7 is the power source for the automatic locking function, and it is fixedly mounted on the support plate 11. The locking / unlocking actuator 7 is essentially an electrically controlled driver. It can be a miniature DC motor or a stepper motor with an integrated reduction gearbox. Its "output end" is typically the final output shaft of the motor. This output shaft is connected to the steering disk 3 in the previous claim via a coupling. The specific workflow is as follows: When an external device sends an "unlock" command to the main control mechanism of the container, the processing end of the main control mechanism verifies the validity of the command and generates a specific drive signal. Based on this signal, the drive circuit controls the motor to rotate in the "unlock" direction. The rotation of the motor directly drives the steering disk 3 to rotate synchronously through the output shaft. The rotation of the rudder disk 3 is converted into the synchronous linear retraction motion of all telescopic unit pins 4 through mechanical transmission (pull rod 5, etc.), thereby achieving automatic unlocking. Conversely, when locking is required, the main control mechanism controls the motor to rotate in the opposite direction, driving the rudder disk 3 to rotate to the locked position, causing all pins 4 to extend and insert into the cylinder locking hole, completing automatic locking.

[0036] like Figure 4 As shown, in one embodiment of this application, the main control mechanism includes a main controller 8, a first infrared transceiver 9, and an infrared communication window 10. The main controller 8 and the first infrared transceiver 9 are located inside the housing 2. The main controller 8 is connected to the first infrared transceiver 9. The infrared communication window 10 is located on the lid 1. The first infrared transceiver 9 can transmit infrared signals through the infrared communication window 10.

[0037] Specifically, the main controller 8 of this application can be a microcontroller. On one hand, it receives infrared communication commands to drive the locking mechanism; on the other hand, it monitors the status of the microswitch in real time, triggering the anti-tamper self-locking logic, thus achieving integrated "communication-control-detection". The first infrared transceiver 9 is responsible for receiving infrared light signals from the outside, converting them into electrical signals, decoding them, and then transmitting them to the main controller 8 for processing. The infrared communication window 10 is a special optical channel set on the lid 1, ensuring that the first infrared transceiver 9 inside the lid 1 is oriented directly towards the window. When an external device needs to interact with the container, the infrared command light signal emitted by the external device penetrates the window, is received by the first infrared transceiver 9 inside the container, and is transmitted to the main controller 8.

[0038] In one embodiment of this application, the main control mechanism further includes a wireless charging coil, which is connected to the main controller 8.

[0039] Specifically, the bucket lid 1 has a built-in wireless power receiving coil, eliminating the need for a built-in battery. During operation, it obtains power through inductive coupling with the wireless power module integrated into the end of the external robotic arm. The instantaneous power consumption during the unlocking or unlocking process is only 3-4 watts, and the power consumption is 0 after disconnection, completely solving the problem of charging dependence. When the robotic arm grasps the bucket lid 1, it automatically aligns the position of the power supply coil without manual calibration, ensuring power supply stability and meeting the energy consumption requirements of the locking mechanism and the microcontroller.

[0040] The present invention also discloses a coal sample storage system, including a robotic arm and the aforementioned storage container; the end of the robotic arm is provided with a pneumatic gripper, which can hold the lid 1 of the container, and the pneumatic gripper is provided with a wireless control module, which can transmit control signals to the main control mechanism.

[0041] Specifically, the wireless control module includes a second infrared transceiver, an infrared communication window 10 on the bucket lid 1, and a first infrared transceiver 9 that are adapted to the second infrared transceiver of the robotic arm. When the robotic arm gripper clamps the bucket lid 1, the communication windows of the two automatically align, enabling the transmission and reception of lock / unlock commands, as well as the interaction of data such as status feedback.

[0042] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects: This application reduces maintenance and usage costs: wireless inductive power supply eliminates the need for battery replacement or charging, reducing maintenance workload by approximately 60% annually and lowering consumable and labor costs; the combination of linear bearings and rubber rings reduces the frictional resistance of the locking mechanism by more than 40%, bringing the coal dust intrusion rate close to zero; the anti-disassembly self-locking and return-to-factory reset mechanism completely eliminates illegal disassembly and coal sample tampering, ensuring the authenticity and reliability of coal sample testing data; automatic power supply adaptation and infrared communication linkage with the robotic arm realize the full automation of the "grabbing-power supply-command-feedback" process without manual intervention, improving operational efficiency by more than 85%; the pneumatic gripper drive with hidden coil design reduces the number of parts, enabling mass production after mold finalization and reducing manufacturing costs.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
