Description

Technical Field

[0001] The invention relates to the technical field of coal mine monitoring, in particular to a coal seam multi-point temperature measuring device. Background Art

[0002] As global energy demand continues to grow, coal, as an important energy source, has received increasing attention for its mining and utilization efficiency. The internal temperature of coal seams has a significant impact on coal mine safety, coal gasification and pyrolysis, and coalbed methane mining. Therefore, accurately measuring the temperature changes of coal seams has become a key link in coal mine safety production and rational resource utilization.

[0003] Traditional coal seam temperature measurement methods often rely on surface or wellhead temperature sensors, which have the disadvantages of limited measurement depth and slow response, making it difficult to accurately reflect the true temperature conditions deep in the coal seam.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a coal seam multi-point temperature measurement device, which has the following beneficial effects:

[0020] 1. The present invention uses a support component to ensure that there are measurement components at coal seams of different depths. When measuring the temperature of coal seams of different depths, the extrusion component is directly pushed downward, and the extrusion component is made to squeeze the pushing component at that position, so that the corresponding measuring component can be moved out from the inside of the support and then inserted into the inside of the coal seam. The above arrangement enables the device to complete the temperature measurement of coal seams of different depths, and perform final data analysis based on the temperature of coal seams of different depths, so that the data obtained when measuring the temperature of the coal seam is relatively accurate.

[0021] 2. The present invention drives the arc extrusion block to move downward through the extrusion rod, and makes the arc extrusion block contact with the two arc surfaces on the pressing block. At this time, the arc extrusion block that continues to move downward can squeeze the pressing block, and the pressing block pushes the temperature sensor out from the inside of the measuring hole through the moving rod, and makes the temperature sensor move to the inside of the coal seam. When the arc extrusion block is no longer squeezing the pressing block, the pushing spring pushes the moving rod through the pushing plate, and makes the temperature sensor move to the inside of the measuring hole again. The above arrangement enables the temperature sensors at different positions to normally complete the temperature measurement of the corresponding coal seams. At the same time, the temperature sensor will only move out of the measuring hole when the arc extrusion block squeezes the corresponding pressing block, so that when the insertion tube is inserted into the coal seam, under the shielding of the measuring hole, the friction between the coal seam and the insertion tube will not cause damage to the temperature sensor.

[0022] 3. The present invention can push the fixing rod into the fixing hole through the fixing spring, so that the extrusion rod fixes the fixing rod. At the same time, the arc-shaped extrusion block just squeezes one of the pressing blocks. Since the fixing hole and the measuring hole are arranged correspondingly, the operator can judge the extrusion situation of the arc-shaped extrusion block on several pressing blocks by whether the fixing rod can complete the fixation of the extrusion rod through the fixing hole. This arrangement makes it more convenient to operate when moving several temperature sensors out of the corresponding measuring holes and measuring the temperature of coal seams at different depths.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0034] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, this application proposes a coal seam multi-point temperature measurement device.

[0035] See also Figure 1-9 A coal seam multi-point temperature measuring device includes a support component 1, a plurality of measuring components 2 are arranged inside the support component 1, a pushing component 3 is arranged on the inner wall of the support component 1 corresponding to the measuring component 2, a pushing component 4 is arranged inside the support component 1, an extrusion component 5 is arranged inside the pushing component 4, and the extrusion component 5 is dynamically connected to the moving end of the pushing component 3.

[0036] The support component 1 is used to drive the measuring component 2 to move to the interior of the coal seam, the pushing component 3 is used to pull the measuring component 2, the squeezing component 5 is used to squeeze the pushing component 3 to move the measuring component 2 out from the interior of the support component 1, and the pushing component 4 is used to push the coal out of the interior of the support component 1.

[0037] When inspecting the coal seam, the support component 1 is directly inserted into the interior of the coal seam, so that the support component 1 drives several measuring components 2 to move into the interior of the coal seam, and then the extrusion component 5 is moved downward, so that the extrusion component 5 can extrude one of the pushing components 3, so that the pushing component 3 can move the corresponding measuring component 2 out from the interior of the support component 1. At this time, the measuring component 2 starts to detect the temperature inside the coal seam.

[0038] Through the support component 1, several measuring components 2 are moved to the interior of the coal seam, so that there are measuring components 2 at coal seams of different depths. When measuring the temperature of coal seams of different depths, the extrusion component 5 is directly pushed downward, and the extrusion component 5 squeezes the pushing component 3 at that position, so that the corresponding measuring component 2 can be moved out from the interior of the support component 1 and then inserted into the interior of the coal seam. The above-mentioned arrangement enables the device to complete the measurement of coal seams of different depths, and perform final data analysis based on the temperature of coal seams of different depths, so that the data obtained when measuring the temperature of the coal seam is relatively accurate.

[0039] Furthermore, for the above-mentioned support assembly 1, the support assembly 1 includes an insertion tube 101, the bottom of the insertion tube 101 is arranged obliquely, the outer surface of the insertion tube 101 is fixedly connected to a support plate 102, and the top of the support plate 102 is fixedly connected to an L-shaped handle 103.

[0040] By directly inserting the insertion tube 101 into the interior of the coal seam, the insertion tube 101 is tilted at its bottom end, so that the resistance encountered by the insertion tube 101 when moving inside the coal seam is small, thereby making it easier to press the insertion tube 101 downward. At the same time, when the insertion tube 101 is inserted into the interior of the coal seam, the support plate 102 can be in contact with the top of the coal seam. This arrangement prevents the insertion tube 101 from sinking at will when the temperature of the coal seam is detected. The L-shaped handle 103 is configured so that there is a certain distance between the holding end and the support plate 102. This arrangement makes it easier to pull out the insertion tube 101 from the coal seam through the L-shaped handle 103.

[0041] Furthermore, for the above-mentioned measuring component 2, the measuring component 2 includes a measuring hole 201, and a plurality of the measuring holes 201 are arranged in an array on the outer surface of the insertion tube 101. The inner wall of the insertion tube 101 is fixedly connected with a storage box 202 corresponding to the measuring hole 201, and the interior of the storage box 202 is movably connected with a moving rod 203, one end of the moving rod 203 passes through the storage box 202 and is fixedly installed with a temperature sensor 204, and the temperature sensor 204 is arranged inside the measuring hole 201.

[0042] When the insertion tube 101 is inserted into the coal seam, several temperature sensors 204 can be located in the corresponding measuring holes 201. This arrangement ensures that when the insertion tube 101 moves downward, the friction between the coal seam and the insertion tube 101 will not damage the temperature sensors 204. When measuring the temperature of coal seams at different depths, the corresponding moving rods 203 can be moved so that the moving rods 203 push the corresponding temperature sensors 204, and the temperature sensors 204 can be moved out of the corresponding measuring holes 201 and directly inserted into the coal seam, and then the temperature of the coal seam at that position can be measured.

[0043] Furthermore, for the above-mentioned pushing component 3, the pushing component 3 includes a pushing plate 301, the pushing plate 301 is movably connected to the storage box 202, the other end of the moving rod 203 is fixedly connected to the pushing plate 301, a pushing spring 302 is fixedly connected between the inner wall of the storage box 202 and the pushing plate 301, and a pressing block 303 is provided on the outer side of the storage box 202, one end of the pressing block 303 extends to the interior of the storage box 202 and is fixedly connected to the pushing plate 301.

[0044] The push spring 302 can push the push disk 301, so that the push disk 301 contacts the inner wall of the storage box 202, so that the moving rod 203 will not move arbitrarily inside the storage box 202 under the push of the push disk 301, and the overall elastic force of the push spring 302 is relatively large, so when the insertion tube 101 is inserted into the coal seam, the coal inside the insertion tube 101 will not squeeze the pressing block 303, and the temperature sensor 204 will not move out of the measuring hole 201 at will, so that the temperature sensor 204 will not move arbitrarily when not in use, and the effect of protecting the temperature sensor 204 through the measuring hole 201 can be guaranteed.

[0045] Furthermore, for the above-mentioned pushing assembly 4, the pushing assembly 4 includes a pushing barrel 401, the pushing barrel 401 is movably connected to the insertion barrel 101, the inner wall of the insertion barrel 101 is provided with a guide groove 402, the inside of the guide groove 402 is movably connected with a guide block 403, the guide block 403 is fixedly connected to the outer surface of the pushing barrel 401, the top of the pushing barrel 401 is provided with an avoidance groove 404 corresponding to the storage box 202, and the outer surface of the pushing barrel 401 is fixedly connected to a handle 405.

[0046] After completing the temperature measurement of the coal seam, while pulling the insertion tube 101 upward, the push tube 401 is pushed downward by connecting the handle 405, so that the push tube 401 can push out the coal inside the insertion tube 101. This setting makes it possible to not damage the coal seam when the insertion tube 101 is pulled out. At the same time, the storage box 202 is inside the avoidance groove 404, and the guide groove 402 can guide the push tube 401 through the guide block 403, so that when the push tube 401 moves downward, the storage box 202 will not cause obstruction. When the push tube 401 pushes the coal downward, the coal inside the avoidance groove 404 can flow downward together with the downwardly flowing coal. This phenomenon makes the setting of the avoidance groove 404 not affect the pushing effect of the push tube 401.

[0047] Furthermore, for the above-mentioned support plate 102, the top of the support plate 102 is fixedly connected to the installation box 406, the outer surface of the push barrel 401 is provided with a locking hole 407, the locking hole 407 extends to the interior of the installation box 406, the interior of the locking hole 407 is movably connected with a locking block 408, the inner wall of the installation box 406 is fixedly connected with a guide rod 409, the guide rod 409 is movably connected to the locking block 408, a locking spring 412 is fixedly connected between one side of the locking block 408 and the inner wall of the installation box 406, a pulling rod 410 is fixedly connected to one side of the locking block 408, one end of the pulling rod 410 passes through the installation box 406 and is fixedly connected to a pulling plate 411.

[0048] The locking spring 412 can push the locking block 408 so that the locking block 408 can move to the inside of the locking hole 407 set on the push barrel 401. At this time, the locking block 408 can lock the push barrel 401 through the locking hole 407, so that when the insertion barrel 101 is inserted into the coal seam, the push barrel 401 will not move downward at will. When pushing the material, the pulling rod 410 is directly pulled through the pulling plate 411, and the pulling rod 410 pulls the locking block 408 and moves the locking block 408 out of the locking hole 407, so that the push barrel 401 can move downward normally.

[0049] Furthermore, for the above-mentioned extrusion component 5, the extrusion component 5 includes a movable groove 501, the movable groove 501 is opened at the top of the push barrel 401, the movable groove 501 is connected with the avoidance groove 404, the inside of the movable groove 501 is movably connected with the extrusion rod 502, the inside of the avoidance groove 404 is movably connected with the arc-shaped extrusion block 503, one side of the arc-shaped extrusion block 503 is fixedly connected with a connecting block 504, the connecting block 504 is fixedly connected with the extrusion rod 502, the inner wall of the movable groove 501 is opened with a limiting groove 505, the inside of the limiting groove 505 is movably connected with a limiting strip 506, and the limiting strip 506 is fixedly connected to the extrusion rod 502.

[0050] When measuring the temperature of the coal seam, the extrusion rod 502 is moved to the inside of the moving groove 501, and the connecting block 504 and the arc extrusion block 503 are moved to the inside of the avoidance groove 404, and then the extrusion rod 502 is moved downward. At the same time, the connecting block 504 and the arc extrusion block 503 move downward in the avoidance groove 404 driven by the extrusion rod 502. When the arc extrusion block 503 moves to the upper side of the pressing block 303, since one end of the pressing block 303 is also arc-shaped, the arc surface on the arc extrusion block 503 can contact the arc surface on the pressing block 303. At the same time, as the arc extrusion block 503 continues to move downward, the arc extrusion block 503 can squeeze the pressing block 303. At this time, the pressing block 303 can move the temperature sensor 204 out of the measuring hole 201 through the moving rod 203, and the temperature sensor 204 can be moved to the inside of the coal seam. When the arc-shaped extrusion block 503 continues to move downward and separates from the pressing block 303 at this position, the pushing spring 302 at this position pushes the moving rod 203 through the pushing plate 301, and the temperature sensor 204 moves to the inside of the measuring hole 201 again, and then repeats the above process, so that the arc-shaped extrusion block 503 can press the pressing blocks 303 at different depths, and several temperature sensors 204 can measure the temperature of the coal seam at the location. The arc-shaped extrusion block 503 and the pressing block 303 contact surface are set in an arc shape, so that when the coal inserted into the cylinder 101 is pushed by the pushing cylinder 401, the arc-shaped extrusion block 503 can move upward normally under the drive of the extrusion rod 502, and move past several pressing blocks 303, and then move out from the inside of the moving groove 501. When the squeezing rod 502 moves inside the moving groove 501 , the limiting groove 505 can limit the squeezing rod 502 through the limiting bar 506 , so that the squeezing rod 502 will not rotate arbitrarily when the arc-shaped squeezing block 503 squeezes the pressing block 303 .

[0051] Furthermore, for the above-mentioned extrusion rod 502, a plurality of fixing holes 507 are opened on the outer surface of the extrusion rod 502 corresponding to the measuring hole 201, the top of the pushing cylinder 401 is fixedly connected with a fixing cylinder 508, the interior of the fixing hole 507 is movably connected with a fixing rod 509, the fixing rod 509 passes through the fixing cylinder 508, the interior of the fixing cylinder 508 is movably connected with a connecting disk 510, the fixing rod 509 is fixedly connected to the connecting disk 510, a fixing spring 511 is fixedly connected between the connecting disk 510 and the inner wall of the fixing cylinder 508, and one end of the fixing rod 509 is fixedly connected with a pulling disk 512.

[0052] When the arc-shaped extrusion block 503 extrudes the pressing block 303, the fixed rod 509 just corresponds to the fixed hole 507 on the extrusion rod 502. At this time, the fixed spring 511 pushes the fixed rod 509 through the connecting plate 510, and moves the fixed rod 509 to the inside of the fixed hole 507, so that the extrusion rod 502 will not change arbitrarily under the fixation of the fixed rod 509. At the same time, the extrusion condition of the arc-shaped extrusion block 503 on several pressing blocks 303 can be judged by whether the fixed rod 509 can complete the fixation of the extrusion rod 502 through the fixed hole 507. At the same time, the setting of the fixed extrusion rod 502 can be carried out so that when the temperature of the coal seam at a certain depth is continuously measured, the condition that the arc-shaped extrusion block 503 extrudes the pressing block 303 at that position can be guaranteed. When the extrusion rod 502 is moved downward, the fixing rod 509 is directly pulled by the pulling plate 512, so that the fixing rod 509 can be moved out from the inside of the fixing hole 507, and the extrusion rod 502 can be moved downward normally, so that the operation is relatively convenient when adjusting the position of the extrusion rod 502.

[0053] Through the above technical solution, 1. The support component 1 enables the presence of the measuring component 2 at each coal seam of different depths, and when measuring the temperature of the coal seams of different depths, the extrusion component 5 is directly pushed downward, and the extrusion component 5 is made to squeeze the pushing component 3 at that position, so that the corresponding measuring component 2 can be moved out from the inside of the support component 1 and then inserted into the inside of the coal seam. The above arrangement enables the device to complete the measurement of the coal seams of different depths, and perform the final data analysis according to the temperature of the coal seams of different depths, so that the data obtained when measuring the temperature of the coal seams is relatively accurate; 2. The arc-shaped extrusion block 503 is driven to move downward by the extrusion rod 502, and the arc-shaped extrusion block 503 is brought into contact with the two arc-shaped surfaces on the pressing block 303. At this time, the arc-shaped extrusion block 503 that is continuously moving downward can squeeze the pressing block 303, and the pressing block 303 pushes the temperature sensor 204 out of the measuring hole 201 through the moving rod 203, and the temperature sensor 204 can be moved to the inside of the coal seam. When the arc-shaped extrusion block 503 is no longer squeezing the pressing block 303, the pushing spring 302 pushes the moving rod 203 through the pushing plate 301, and The temperature sensor 204 is moved to the inside of the measuring hole 201 again. The above arrangement enables the temperature sensors 204 at different positions to normally complete the temperature measurement of the corresponding coal seam. At the same time, the temperature sensor 204 will only move out of the measuring hole 201 when the arc-shaped extrusion block 503 squeezes the corresponding pressing block 303, so that when the insertion tube 101 is inserted into the inside of the coal seam, under the shielding of the measuring hole 201, the friction between the coal seam and the insertion tube 101 will not cause damage to the temperature sensor 204; 3. The fixing rod 509 can be pushed to the fixing hole by the fixing spring 511 507, so that the extrusion rod 502 fixes the fixing rod 509, and at the same time, the arc-shaped extrusion block 503 just squeezes one of the pressing blocks 303. Since the fixing hole 507 is arranged corresponding to the measuring hole 201, the operator can judge the extrusion situation of the arc-shaped extrusion block 503 on several pressing blocks 303 by whether the fixing rod 509 can complete the fixation of the extrusion rod 502 through the fixing hole 507. This arrangement makes it convenient to operate when moving several temperature sensors 204 out of the corresponding measuring holes 201 and measuring the temperature of coal seams at different depths.

[0054] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
