[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] Specific examples are given below. Figures 1-6 .

[0031] Example 1:

[0032] See also Figure 1-Figure 2 The present invention provides a technical solution: a fully automatic measurement device for outburst hazard prediction indicators, including a casing 1 and a bracket 2, wherein the bracket 2 is provided with a tray 3, the tray 3 is provided with a storage seat 31, and the storage seat 31 is provided with a coal cup 311 containing a coal sample; a micro-pressure differential sensor 11 is embedded in the inner wall of the casing 1, and the micro-pressure differential sensor 11 is used to measure the tiny pressure difference in the casing 1, a solenoid valve 12 is provided on the side wall of the casing 1, a weighing module 4 and a level 5 are sequentially provided on the side of the tray 3 close to the bracket 2, and a battery 13, a circuit board 131, a wireless transmission module 132, an MCU main control module 133 and a power control module 134 are provided in the casing 1.

[0033] Reference Figure 2 and Figure 3 The weighing module 4, composed of multiple load cells, measures the weight of the coal cup 311. A level 5 levels the tray 3. A solenoid valve 12 connects the interior of the casing 1 to the atmosphere, exposing the coal sample. A micro-differential pressure sensor 11 measures the minute pressure differential within the casing 1.

[0034] Battery 13 powers the solenoid valve 12, circuit board 131, wireless transmission module 132, MCU main control module 133, and power control module 134. Power control module 134 monitors the voltage of battery 13. When the voltage falls below a set value, it sends a signal to the data monitoring cloud platform and mobile app, indicating that charging is needed. MCU main control module 133 is a single-chip microcomputer based on the ESP chip.

[0035] Reference Figure 2 and Figure 3 The wireless transmission module 132 is a wireless communication module based on the NB-LOT narrowband Internet of Things; NB-LOT technology supports cellular data connection of low-power devices in the wide area network, and NB-LOT supports efficient connection of devices with long standby time and high network connection requirements.

[0036] The weighing module 4 converts the mass value of the coal sample into an electrical signal and transmits it to the MCU main control module 133 through the SPI serial communication protocol. The MCU main control module 133 then transmits the electrical signal to the data monitoring cloud platform or mobile phone APP through the wireless transmission module 132.

[0037] Reference Figure 2 and Figure 3A micro-differential pressure sensor 11, located at the top of the inner wall of the housing 1, converts the tiny pressure differential within the housing 1 into an electrical signal and transmits it to the MCU main control module 133 via the SPI serial communication protocol. The MCU main control module 133 then transmits the electrical signal to a data monitoring cloud platform or mobile phone app via a wireless transmission module 132. The solenoid valve 12 is connected to the MCU main control module 133 via the UART serial communication protocol. A display screen 14 is installed on the outer wall of the housing 1 to display test values ​​and facilitate control of various components within the housing 1.

[0038] Reference Figure 1 To improve the accuracy of the test, a door panel 15 is rotatably connected to the housing 1 and fixed to the housing 1 via elastic buckles. A sealing gasket 152 is provided on the side of the door panel 15 close to the housing 1. The sealing gasket 152 is made of rubber to improve the sealing between the door panel 15 and the housing 1.

[0039] Working Principle: A worker sieves a coal sample obtained from a drilled hole into a particle size of 1-3 mm and fills the sample cup. The surface of the sample is then scraped flat. The coal cup 311 containing the sample is placed on a tray 3 and balanced using a spirit level 5. The door 15 is then closed, sealing the desorption chamber. Solenoid valve 12 opens, connecting the housing 1 to the atmosphere. It closes after the solenoid valve 12 has been open for a set time. A micro-differential pressure sensor 11 then measures the pressure inside the housing 1 to obtain the final reading.

[0040] Example 2:

[0041] Reference Figure 4 and Figure 5 , which is different from the first embodiment of the present application in that: the bracket 2 is slidably connected to the casing 1, a control component 6 is provided in the bracket 2, the tray 3 is slidably connected to the bracket 2, the control component 6 is used to control the reciprocating movement of the tray 3 along the length direction of the bracket 2, and an adjustment component 7 is provided on the tray 3, which is used to adjust the opening size of the coal cup 311.

[0042] Reference Figure 4 To facilitate the movement of bracket 2, the inner wall of housing 1 is provided with a drive slot 16 and a guide slot 17. A screw 161 is rotatably connected to drive slot 16, while a guide rod 171 is fixed to guide slot 17. Bracket 2 extends into drive slot 16 and guide slot 17, respectively, with bracket 2 threadedly connected to screw 161 and slidingly connected to guide rod 171. Both drive slot 16 and guide slot 17 are provided with corrugated plates 18. The corrugated plates 18 in drive slot 16 are connected to bracket 2, while the corrugated plates 18 in guide slot 17 are connected to bracket 2. Screw 161 is externally connected to a motor.

[0043] The motor controls the movement of screw 161, which, guided by guide rod 171, controls the movement of bracket 2 to adjust the position of bracket 2. As bracket 2 moves, corrugated plate 18 moves accordingly, preventing coal samples from falling into drive groove 16 and guide groove 17. Furthermore, impurities in guide groove 17 and drive groove 16 are less likely to affect the accuracy of the measurement device.

[0044] Reference Figure 5 The control assembly 6 includes a drive plate 61, a connecting plate 62, and a movable plate 63. The drive plate 61 is rotatably connected to the bracket 2, and the connecting plate 62 is rotatably connected to the drive plate 61. The movable plate 63 is rotatably connected to the end of the connecting plate 62 facing away from the drive plate 61. The bracket 2 is defined with a movable groove 21, and the movable plate 63 is slidably connected to the movable groove 21. The tray 3 is disposed on the side of the movable plate 63 facing away from the bracket 2.

[0045] In order to conveniently control the rotation of the driving plate 61, the rotating shaft of the driving plate 61 extends out of the bracket 2 and is connected to the first gear 611. A first rack 19 is fixed in the housing 1, and the first rack 19 is parallel to the moving direction of the bracket 2. The first gear 611 is engaged with the first rack 19.

[0046] As the bracket 2 moves, the first rack 19 causes the first gear 611 to rotate. This in turn drives the drive plate 61 and the connecting plate 62. Guided by the movable slot 21, the connecting plate 62 rotates, driving the movable plate 63 along the movable slot 21. The movable plate 63 then sequentially controls the movement of the tray 3, the storage seat 31, and the coal cup 311, enabling real-time adjustment of the position of the coal cup 311. This simulates the uneven distribution of coal in an underground mine, enhancing the simulation's realism and, consequently, the measurement device's accuracy.

[0047] Reference Figure 5 and Figure 6 The adjustment assembly 7 includes a baffle 71 and an adjustment member. The tray 3 is rotatably connected to the main shaft 32. The baffle 71 is fixed to the main shaft 32, and the adjustment member is connected to the main shaft 32.

[0048] The adjusting member includes a first synchronous wheel 72, a second synchronous wheel 73, and a second gear 74. The first synchronous wheel 72 is fixed to the end of the main shaft 32 away from the baffle 71. The tray 3 is rotatably connected to the secondary shaft 33. The second synchronous wheel 73 is fixed to one end of the secondary shaft 33. The second gear 74 is fixed to the end of the secondary shaft 33 away from the second synchronous wheel 73. A synchronous belt 75 is wound around the second synchronous wheel 73 and the first synchronous wheel 72. A second rack 22 is fixed to the bracket 2 along its length, and the second gear 74 meshes with the second rack 22. The first synchronous wheel 72 and the second synchronous wheel 73 are configured as synchronous belts 75, and the synchronous belt 75 is configured as a synchronous toothed belt.

[0049] As the movable plate 63 moves, the second rack 22 drives the second gear 74 to rotate. This in turn drives the countershaft 33, the second synchronous pulley 73, the synchronous belt 75, and the first synchronous pulley 72. The first synchronous pulley 72 in turn drives the main shaft 32, which in turn drives the baffle 71. The baffle 71 can then adjust the opening size of the coal cup 311 to simulate different exposed areas in an underground coal mine, enhancing the simulation's realism and further improving the detection accuracy of the measurement device.

[0050] The operating principle of the second embodiment of the present application is as follows: bracket 2 and control assembly 6 are activated synchronously to adjust the position of coal cup 311 in real time, simulating the varying distribution of coal mines underground. Simultaneously, adjustment assembly 7 is activated to adjust the opening size of coal cup 311 in real time, simulating the varying exposed areas at different locations in the underground coal mine. This improves the realism of the simulation and thus the detection accuracy of the measuring device.
