Description

Technical Field

[0001] This invention relates to the technical field of gas monitoring instruments, and more particularly to a BIM-based mine gas monitoring device. Background Technology

[0002] A mine shaft is a general term encompassing the tunnels, chambers, equipment, surface buildings, and structures that form an underground coal mine production system. Sometimes, inclined shafts, vertical shafts, and adits in underground mine development are also referred to as mine shafts. Determining the size of each mine's mining area, its production capacity, and its service life is one of the key issues that must be addressed in the mine's self-design. Before construction, mines utilize BIM (Building Information Modeling) technology. BIM is not merely a simple integration of digital information, but rather an application of digital information, a digital method used for design, construction, and management. A Building Information Model uses various relevant information and data of a building project as a foundation, simulating the real information of the building through digital information. Construction is then carried out according to the Building Information Model. When workers are constructing underground according to the Building Information Model, gas monitoring instruments are required.

[0003] In existing technologies, since gas monitors are installed on the inner wall of mines, protective devices are installed on top of the gas monitors during construction to prevent small falling rocks from damaging them. These protective devices are mostly installed using bolts, which is cumbersome. Furthermore, because the gas monitors are constantly in use, their high temperatures can easily burn out the internal electrical components. Therefore, this invention proposes a BIM-based mine gas monitoring device. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems existing in the current BIM-based mine gas monitoring devices, this invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a BIM-based mine gas monitoring device.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including a protective mechanism, comprising a column, a shielding cover disposed on the column, a support leg disposed on the side of the column, and a movable groove disposed inside the column; an installation mechanism, comprising a connecting block, a driving component disposed on the connecting block, and a limiting component disposed on the driving component; and a contact mechanism, comprising a power component and a heat-conducting component connected to the power component.

[0008] As a preferred embodiment of the BIM-based mine gas monitoring device of the present invention, the column is provided with an I-shaped groove on one side that communicates with the moving groove; a translation groove is provided on the side of the connecting block near the I-shaped groove, and the I-shaped groove corresponds to the translation groove.

[0009] As a preferred embodiment of the BIM-based mine gas monitoring device of the present invention, the driving assembly includes a first spring with one end connected to the inner wall of the moving groove, a driving plate disposed inside the moving groove, a connecting rod mounted on the connecting block, and an auxiliary block connected to the connecting rod.

[0010] As a preferred embodiment of the BIM-based mine gas monitoring device of the present invention, the following features are provided: a gas monitor is provided at the bottom of the column, and a connecting groove is provided on the surface of the column; the gas monitor is provided with a plug-in groove that matches the column, one end of the column is located inside the plug-in groove, and a heat sink is installed on the gas monitor; the connecting groove and the limiting groove are both used to limit the column by the limiting component.

[0011] As a preferred embodiment of the BIM-based mine gas monitoring device of the present invention, the gas monitor is equipped with a heat sink; the heat sink is in contact with the heat-conducting component.

[0012] As a preferred embodiment of the BIM-based mine gas monitoring device of the present invention, the limiting component includes a push plate connected to the bottom of the auxiliary block and a limiting plate connected to the push plate; one end of the limiting plate extends into the interior of the limiting groove.

[0013] As a preferred embodiment of the BIM-based mine gas monitoring device of the present invention, the power assembly includes a first trapezoidal block disposed at the bottom of the limiting plate and a second trapezoidal block disposed inside the moving groove, a telescopic rod disposed on the second trapezoidal block, and a second spring sleeved on the surface of the telescopic rod; the inclined surfaces of the first trapezoidal block and the second trapezoidal block correspond to each other; the ends of the telescopic rod and the second spring away from the second trapezoidal block are both connected to the inner wall of the moving groove.

[0014] As a preferred embodiment of the BIM-based mine gas monitoring device of the present invention, the column is provided with a through slot for connecting the moving trough and the interior of the gas monitor; the heat conduction component is connected to the second trapezoidal block through the through slot.

[0015] As a preferred embodiment of the BIM-based mine gas monitoring device of the present invention, the heat conduction component includes a fixing block disposed at the bottom of the second trapezoidal block, a mounting plate disposed on the fixing block, and a plurality of contact plates disposed on the mounting plate.

[0016] As a preferred embodiment of the BIM-based mine gas monitoring device of the present invention, the column, the second trapezoidal block, the fixing block, the mounting plate and the multiple contact plates are all made of thermally conductive materials.

[0017] The beneficial effects of this invention are as follows: By operating the drive component, the drive component moves the connecting block, which in turn moves the two limiting components. These limiting components then limit the insertion of the column into the gas monitor, thus enabling rapid installation of the column. Simultaneously, the two limiting components cooperate with two power components, causing them to drive the power components. This, in turn, causes the heat-conducting components to contact the surfaces of multiple heat sinks inside the gas monitor. This conducts heat from some of the heat sinks through the heat-conducting components, increasing the gas monitor's heat dissipation effect and preventing the problem of high internal temperatures and potential burnout of internal electrical components caused by prolonged use.

[0029] Example 1 Reference Figures 1-7 This paper presents a schematic diagram of the overall structure of a BIM-based mine gas monitoring device, as shown in the figure. Figure 1A BIM-based mine gas monitoring device includes a protective mechanism 100, comprising two vertically arranged columns 101, a shield 102 on the two columns 101 (the shield 102 is used to block falling rocks and prevent them from directly hitting the gas monitor 106 and causing damage), three legs 103 on three sides of each column 101 (when the legs 103 contact the top of the gas monitor 106, the column 101 is inserted into the appropriate position in the insertion slot 108), and a moving groove 104 inside the column 101; and an installation mechanism 200, which enables quick installation of the columns 101, including a connecting block 201 inside the moving groove 104, a drive assembly 202 on the connecting block 201, and two limiting components 203 on the drive assembly 202. The connecting block 201 drives the operation of the two limiting components 203, which limit the column 101, thereby enabling the rapid installation of the column 101. The contact mechanism 300 includes two power components 301 that cooperate with the two limiting components 203, and a heat-conducting component connected to the two power components 301. When the limiting components 203 operate, they drive the two power components 301, causing the heat-conducting component to contact the surface of multiple heat sinks 1010 inside the gas monitor 106. This allows the heat sinks 1010 to conduct heat away through the heat-conducting component, increasing the heat dissipation effect of the gas monitor 106 and preventing the gas monitor 106 from overheating during prolonged use, which could easily burn out the internal electrical components.

[0030] The column 101 has an I-shaped groove 105 on one side that communicates with the moving groove 104. The I-shaped groove 105 consists of two horizontal grooves and one vertical groove. The two horizontal grooves are connected by the vertical groove. The connecting block 201 has a translation groove 201a on the side near the I-shaped groove 105. The two horizontal grooves correspond to the translation groove 201a. The I-shaped groove 105 and the translation groove 201a are both matched with the moving trajectory of the drive board 202b.

[0031] Furthermore, the drive assembly 202 includes a first spring 202a with one end connected to the inner wall of the moving groove 104, the end of the first spring 202a away from the inner wall of the moving groove 104 connected to the connecting block 201, a drive plate 202b disposed inside the translation groove 201a, one end of the drive plate 202b extending out of the translation groove 201a and the I-shaped groove 105, a connecting rod 202c installed at the bottom of the connecting block 201, and an auxiliary block 202d connected to the connecting rod 202c. First, the drive plate 202b is pushed horizontally, causing it to move along the trajectory of the horizontal groove and the translation groove 201a of the I-shaped groove 105. When the drive plate 202b moves to the vertical groove of the I-shaped groove 105, it is pushed downward. The drive plate 202b causes the connecting block 201 to descend, and the connecting block 201 causes the first spring 202a to stretch. At the same time, the connecting block 201 causes the auxiliary block 202d to descend through the connecting rod 202c.

[0032] Furthermore, a gas monitor 106 is provided at the bottom of the column 101, and two connecting slots 107 are provided on the column 101. The two connecting slots 107 are located on opposite sides of the gas monitor 106. Two plug slots 108 are provided at the top of the gas monitor 106 to match the two columns 101. The ends of the two columns 101 away from the cover 102 are located inside the two plug slots 108. Four limiting slots 109 are provided on the gas monitor 106. Two limiting slots 109 are connected to one of the plug slots 108, and the other two limiting slots 108 are connected to the other plug slot 108. The connecting slots 107 and the limiting slots 109 cooperate with each other to limit the column 101 with the limiting component 203.

[0033] Furthermore, multiple heat sinks 1010 are installed on the two sides of the gas monitor 106 that are far apart from each other. One end of each heat sink 1010 is located inside the gas monitor 106, and the other end of each heat sink 1010 is located outside the gas monitor 106. The heat sinks 1010 are in contact with the heat conduction components.

[0034] Furthermore, the limiting component 203 includes a push plate 203a connected to the bottom of the auxiliary block 202d via a rotating shaft. One end of the push plate 203a away from the auxiliary block 202d is connected to a limiting plate 203b via a rotating shaft. The other end of the limiting plate 203b away from the push plate 203a extends into the interior of the limiting groove 109. When the auxiliary block 202d descends, it pushes the push plate 203a to move. In the initial state, the push plate 203 is inclined, and the first trapezoidal block 301 at the bottom of the limiting plate 203 contacts the inner wall at the bottom of the moving groove. This causes the push plate 203a to push the limiting plate 302b to the side when it pushes again. The push plate 203a pushes the limiting plate 203b out of the moving groove 104 and through the connecting groove 107 into the two limiting grooves 109, thereby limiting the column 101.

[0035] Operation process: When the column 101 is inserted into the insertion slot 108 and the multiple support legs 103 are in contact with the top of the gas monitor 106; 1. Horizontally push the drive plate 202b so that the drive plate 202b moves along the trajectory of the horizontal groove and the translation groove 201a at the top of the I-shaped groove 105. When the drive plate 202b moves to the vertical groove of the I-shaped groove 105; 2. Push the drive plate 202b downwards. The drive plate 202b causes the connecting block 201 to descend, and the connecting block 201 causes the first spring 202a to stretch. 3. Simultaneously, the connecting block 201 drives the auxiliary block 202d to descend via the connecting rod 202c; 4. The auxiliary block 202d pushes the two push plates 203a to move, so that the two push plates 203a push the limiting plate 203b out of the moving groove 104 respectively, and insert it into the two limiting grooves 109 through the two connecting grooves 107 respectively, thereby limiting the column 101; 5. When the drive plate 202b moves along the vertical groove of the I-shaped groove 105 to the horizontal groove at the bottom, the two limiting plates 203b are inserted into the appropriate positions in the two limiting grooves 109. 6. Push the drive plate 202b horizontally so that it deviates from the connection between the horizontal and vertical slots of the I-shaped groove 105. Release your hand, and under the action of the tension of the first spring 202a, the drive plate 202b will fit tightly against the top of the horizontal slot, thus completing the installation of the column 101. 7. Repeat the operation to install another column 101.

[0036] Example 2 Reference Figures 1-7This embodiment differs from the first embodiment in that: the power assembly 301 includes a first trapezoidal block 301a fixedly installed at the bottom of the limiting plate 203b, a second trapezoidal block 301b disposed inside the moving groove 104, a telescopic rod 301c horizontally disposed on the second trapezoidal block 301b, and a second spring 301d sleeved on the surface of the telescopic rod 301c; the inclined surfaces of the first trapezoidal block 301a and the second trapezoidal block 301b correspond to each other; one end of the telescopic rod 301c and the second spring 301d are both connected to the second trapezoidal block 301b, and the other end of the telescopic rod 301c and the second spring 301d are both connected to the inner wall of the moving groove 104, and the limiting plate 203b... When moving, b drives the first trapezoidal block 301a to move (the movement of the limiting plate 203b is the same as in the first embodiment), so that the inclined surface of the first trapezoidal block 301a presses against the inclined surface of the second trapezoidal block 301b. Under the limitation of the telescopic rod 301c, the second trapezoidal block 301b can only move in the telescopic direction of the telescopic rod 301c. The first trapezoidal block 301a pushes the second trapezoidal block 301b to press against the telescopic rod 301c and the second spring 301d, so that the telescopic rod 301c and the second spring 301d contract. The second spring 301d is provided to facilitate the better reset of the second trapezoidal block 301b when the locking of the support column 101 is released.

[0037] Furthermore, the column 101 is provided with two through slots 1011 for connecting the movable slot 104 and the gas monitor 106. The two through slots 1011 are located at the ends of the column 101 away from the shielding cover 102. The two through slots are matched with the moving trajectories of the two fixed blocks 302a. The heat conduction component is connected to the two second trapezoidal blocks 301b through the two through slots respectively.

[0038] Furthermore, the heat-conducting component includes two fixing blocks 302a respectively disposed at the bottom of the second trapezoidal block 301b. The two fixing blocks 302a respectively pass through two through slots and are connected to the top of the mounting plate 302b. Multiple contact plates 302c are installed at the bottom of the mounting plate 302b. The dimensions of the mounting plate 302b and the multiple contact plates 302c are matched with the insertion slots 108, which facilitates the insertion of the mounting plate 302b and the multiple contact plates 302c. Under the drive of the column 101, the multiple contact plates 302c are respectively inserted between the multiple heat sinks 1010. When the two second trapezoidal blocks 301b compress the telescopic rod 301c and the second spring 301d, causing the telescopic rod 301c and the second spring 301d to retract, the two second trapezoidal blocks 301b respectively drive the two The moving of the fixed block 302a causes the two fixed blocks 302a to move the mounting plate 302b. The mounting plate 302b then causes multiple contact plates 302c to respectively contact one side of one of the heat sinks 1010, increasing the contact area of ​​the heat sink 1010 and better conducting the heat from the heat sink 1010 from the multiple contact plates 302c to the mounting plate 302b. The heat is then conducted to the column 101 through the mounting plate 302b, the two fixed blocks 302a, and the two second trapezoidal blocks 301b. The column then dissipates the heat from the gas monitor 106, protecting the internal electrical components of the gas monitor 106 and preventing the problem of high internal temperature and easy burnout of the internal electrical components of the gas monitor 106 due to prolonged use.

[0039] Furthermore, the column 101, the second trapezoidal block 301b, the fixing block 302a, the mounting plate 302b, and the multiple contact plates 302c are all made of thermally conductive materials. This better dissipates the heat inside the gas monitor 106. The thermally conductive material can be metals such as copper or aluminum; if cost is not a concern, silver or gold can be chosen. However, when aluminum or similar materials are chosen, which have lower inherent strength but better thermal conductivity, the column 101 is easily deformed under the impact of falling rocks when it is used to support the cover 102. The shorter service life increases costs. Therefore, in this case, the three legs 103 on each column 101 can directly contact the bottom of the cover 102 and are no longer connected to the column 101. The column 101 only serves to install the cover 102 and increase the heat dissipation of the gas monitor 106, while the six legs 103 provide support. At the same time, a buffer can be installed on the top of the cover 102. The buffer can be a spring or a buffer pad or other components that can be used to buffer the impact of falling rocks, which reduces the impact of falling rocks to a certain extent and better protects the gas monitor.

[0040] Operation process: 1. When the two limiting plates 203b move, they respectively drive the two first trapezoidal blocks 301a to move, so that the inclined surfaces of the two first trapezoidal blocks 301a respectively press against the inclined surfaces of the two second trapezoidal blocks 301b; 2. Under the limitation of the two telescopic rods 301c, the second trapezoidal block 301b can only move in the telescopic direction of the telescopic rods 301c; 3. When the two second trapezoidal blocks 301b move, they respectively drive the two fixed blocks 302a to move; 4. The two 302a drives the mounting plate 302b to move. The mounting plate 302b drives multiple contact plates 302c to respectively attach to one side of one of the heat sinks 1010, increasing the contact area of ​​the heat sink 1010. This better conducts the heat from the heat sink 1010 from the multiple contact plates 302c to the mounting plate 302b, and then through the mounting plate 302b, the two fixing blocks 302a, and the two second trapezoidal blocks 301b to the column 101. The column then dissipates the heat from the gas monitor 106, protecting the electrical components inside the gas monitor 106 and preventing the gas monitor 106 from overheating and burning out due to prolonged use.

[0041] Example 3 Reference Figure 8 The difference between this embodiment and the first and second embodiments is that the support column 101 may be provided with an adjustment component 101a. The support column 101 is connected to the cover 102 through the adjustment component 101. The support column 101 is provided with a threaded groove 101a-1. The adjustment component 101a includes a threaded post 101a-2 disposed inside the threaded groove 101a-1. One end of the threaded post 101a-2 passes through the threaded groove 101a-1 and is connected to the bottom of the cover 102 through a rotating shaft. A round block 101a-3 is fixedly sleeved on the surface of the threaded post 101a-2.

[0042] Operation process: 1. First, twist the two round blocks 101a-3 simultaneously, and the two round blocks 101a-3 will drive the two threaded columns 101a-2 to rotate respectively; 2. The two threaded posts 101a-2 are respectively rotated into or out of the two threaded grooves 101a-1, thereby reducing or increasing the distance between the shielding cover 102 and the support post 101, thus adjusting the distance between the shielding cover 102 and the gas monitor 106, so that the shielding cover 102 can better protect the gas monitor 106.
