[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0026] In the description of this utility model, it should be understood that the term "comprising" as used in this specification means the presence of the stated features, integers, steps, operations, parts, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, parts, components, and / or groups thereof. It should be understood that when we say a part is "connected" to another part, it can be directly connected to the other part, or there may be intermediate parts. The term "and / or" as used herein includes all or any unit and all combinations of one or more associated listed items.

[0027] like Figures 1 to 4 As shown, this utility model relates to a sampling mechanism for monitoring water control in coal mine geological conditions, including a housing 1, a first hoisting assembly, a protective shell 14, a second hoisting assembly, and a sampling assembly. The bottom of the housing 1 has a first opening. The first hoisting assembly and the protective shell 14 are both located inside the housing 1. The first hoisting assembly is used to move the protective shell 14 along the height direction so that the protective shell 14 can pass through the first opening and be lowered outside the housing 1. The bottom of the protective shell 14 has a second opening. The second hoisting assembly and the sampling assembly are both located inside the protective shell 14. The second hoisting assembly is used to move the sampling assembly along the height direction so that the sampling assembly can pass through the second opening and be lowered outside the protective shell 14.

[0028] In this invention, during sampling, the protective housing 14 is lowered using the first lifting assembly. The protective housing 14 moves downwards and is lowered through the first opening to the bottom of the housing 1, ultimately reaching the sampling area. Then, the sampling component is lowered using the second lifting assembly. The sampling component moves downwards and is lowered through the second opening to the bottom of the protective housing 14, allowing it to perform sampling. Therefore, this invention first lowers the protective housing 14 to the sampling area. During this process, the sampling component is protected from impacts and damage, ensuring smooth sampling.

[0029] In this embodiment, a top cover 2 is fixedly connected to the top of the box body 1, a door 4 is hinged to one side of the box body 1, a handle 5 is fixedly connected to one side of the door 4, a heat dissipation hole 3 is provided on one side of the box body 1, anti-collision blocks 6 are installed at the four corners of the bottom of the box body 1, and four universal wheels 7 are equidistantly installed on the bottom surface of the box body 1, thereby facilitating the use of the coal mine geological water control monitoring and sampling mechanism.

[0030] In this embodiment, the housing 1 is provided with a first vertical plate. The first hoisting assembly includes a first rotating roller 9, a first drive motor 8, and a first pull rope 10. The first rotating roller 9 is rotatably connected between the first vertical plate and the inner wall of the housing 1. The first drive motor 8 is fixed to the first vertical plate, and the output shaft of the first drive motor 8 is connected to the first rotating roller 9 to drive the first rotating roller 9 to rotate. One end of the first pull rope 10 is connected to the first rotating roller 9, and the other end of the first pull rope 10 is connected to the protective housing 14.

[0031] That is, the first drive motor 8 can drive the first rotating roller 9 to rotate, thereby controlling the first pull rope 10 to move the protective shell 14 along the height direction to facilitate sampling.

[0032] Preferably, the housing 1 is further provided with a first connecting rod 28 and a first roller 29. There are two first connecting rods 28, which are located between the first rotating roller 9 and the protective housing 14. One end of each of the two first connecting rods 28 is connected to the inner wall of the housing 1 and the first vertical plate, respectively. The other ends of the two first connecting rods 28 are arranged opposite to each other and adjacent to each other. The ends of the two first connecting rods 28 that are close to each other are provided with the first roller 29, and there is a gap between the two first rollers 29. The first pull rope 10 passes through the gap between the two first rollers 29.

[0033] That is, by having the two first rollers 29 clamp the first pull rope 10, the first pull rope 10 is limited, which helps to reduce the shaking of the first pull rope 10 and reduce the shaking amplitude of the protective shell 14 during the lowering process, thus ensuring the smooth sampling.

[0034] In this embodiment, the top of the protective housing 14 is provided with a pull ring 13, and the lower end of the first pull rope 10 is connected to the pull ring 13 to ensure the stability of the connection.

[0035] In this embodiment, two second vertical plates are spaced apart inside the protective housing 14. The second hoisting assembly includes a second rotating roller 16, a second drive motor 15, and a second pull rope 17. The second rotating roller 16 is rotatably connected between the two second vertical plates. The second drive motor 15 is fixed to one of the second vertical plates, and the output shaft of the second drive motor 15 is connected to the second rotating roller 16 to drive the second rotating roller 16 to rotate. One end of the second pull rope 17 is connected to the second rotating roller 16, and the other end of the second pull rope 17 is connected to the sampling assembly.

[0036] That is, by driving the second rotating roller 16 to rotate through the second drive motor 15, the second pull rope 17 can be driven to move the sampling component along the height direction. After the protective housing 14 moves to the sampling area, the sampling component is then driven to be lowered from the second opening of the protective housing 14 to the bottom of the protective housing 14, so that the sampling can be successfully completed.

[0037] Preferably, the protective housing 14 is further provided with a second connecting rod 30 and a second roller 31. There are two second connecting rods 30, which are located between the second rotating roller 16 and the sampling component. One end of each of the two second connecting rods 30 is connected to the two second vertical plates, and the other ends of the two second connecting rods 30 are arranged opposite to each other and adjacent to each other. The ends of the two second connecting rods 30 that are close to each other are provided with the second roller 31, and there is a gap between the two second rollers 31. The second pull rope 17 passes through the gap between the two second rollers 31.

[0038] That is, by clamping the second pull rope 17 with the two second rollers 31, the second pull rope 17 is limited, so that when the second drive motor 15 drives the second pull rope 17 to lower the sampling component, the shaking can be reduced, and the sampling work can be completed smoothly.

[0039] In this embodiment, a door opening and closing assembly is provided at the bottom of the protective housing 14 and at the second opening for opening or closing the second opening.

[0040] The door opening and closing assembly includes a door panel 26, a slide rail 27, a sliding rod 18, a drive rack 11, a drive gear 19, and a door opening drive motor 25. The slide rail 27 is located at the bottom of the protective housing 14 and on one side of the second opening. The sliding rod 18 is connected to the slide rail 27 and can slide along the slide rail 27. The door panel 26 is located on one side of the sliding rod 18 so that the second opening can be opened or closed when the sliding rod 18 moves along the slide rail 27. The drive rack 11 is located on the other side of the sliding rod 18. The drive gear 19 is located at the bottom of the protective housing 14. The door opening drive motor 25 is located inside the protective housing 14, and the output shaft of the door opening drive motor 25 extends to the bottom of the protective housing 14 and is connected to the drive gear 19. The drive gear 19 meshes with the drive rack 11.

[0041] That is, when the door opening drive motor 25 is started, it can drive the drive gear 19 to rotate, thereby driving the sliding rod 18 to slide along the slide rail frame 27 through the drive rack 11, thereby driving the door panel 26 to move, so that the door panel 26 can open or close the second opening. When the door panel 26 closes the second opening, it can protect the inside of the protective housing 14. When the door panel 26 opens the second opening, it can allow the sampling component to pass through the second opening.

[0042] Preferably, two sliding rods 18 are slidably connected to the slide rail frame 27, and two door panels 26 and two drive racks 11 are provided. The two door panels 26 are connected to the two sliding rods 18 respectively, and the two drive racks 11 are connected to the two sliding rods 18 respectively. The drive gear 19 is located between the two drive racks 11 so as to synchronously drive the two door panels 26 to move. When the two door panels 26 are close to each other, the second opening is closed, and when the two door panels 26 are far apart, the second opening is opened.

[0043] In this embodiment, the sampling component includes a sampling mounting frame 20, a sampling bottle 21, and a counterweight 22. The second hoisting component is connected to the top of the sampling mounting frame 20, and the counterweight 22 is fixedly installed at the bottom of the sampling mounting frame 20. The sampling bottle 21 is fitted inside the sampling mounting frame 20, thereby facilitating sampling by the sampling component.

[0044] In this embodiment, a sampling sensor 23 is provided inside the protective housing 14. The sampling sensor 23 is located on the second vertical plate and faces the sampling component.

[0045] In this embodiment, a water level sensor 24 is provided at the bottom of the protective housing 14.

[0046] In this embodiment, the coal mine geological water control monitoring and sampling mechanism further includes a controller 12, which can be installed inside the housing 1 or the protective shell 14. The first drive motor 8, the second drive motor 15, the door opening drive motor 25, the sampling sensor 23, and the water level sensor 24 are all electrically connected to the controller 12.

[0047] The specific working process of the coal mine geological water monitoring and sampling agency:

[0048] The sampling bottle 21 is inserted into the sampling mounting frame 20. The first drive motor 8 is started, driving the first rotating roller 9 to rotate. The rotation of the first rotating roller 9 drives the first pull rope 10 to lower. When the first pull rope 10 is lowered, the protective shell 14 descends naturally. When the bottom of the protective shell 14 approaches the water level, the water level sensor 24 senses this and, through the controller 12, stops the first drive motor 8. At the same time, when the bottom of the protective shell 14 approaches the water level, the water level sensor 24 senses this and, through the controller 12, controls the door opening drive motor 25 to rotate. When the door opening drive motor 25 rotates, it drives the drive gear 19 to rotate. The drive gear 19 drives the drive rack 11 to move, thereby moving the two sliding rods. 18 slides along the slide rail 27 in opposite directions. The two sliding rods 18 drive the two door panels 26 to open in opposite directions. The second drive motor 15 is started to drive the second rotating roller 16 to rotate, so that the second pull rope 17 is lowered. When the second pull rope 17 is lowered, the sampling bottle 21 is submerged in the water for sampling by the counterweight 22. The sampling height is controlled by the second drive motor 15. After the sampling is completed, the second drive motor 15 is started to retract the sampling bottle 21 into the protective shell 14. After the sampling sensor 23 senses that the sampling bottle 21 has been retracted into the protective shell 14, the controller 12 controls the door opening drive motor 25 to close the door. The first drive motor 8 retracts the protective shell 14, completing the sampling work.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
