Description

Technical Field

[0001] This invention belongs to the field of storage device technology, specifically relating to a sample storage device for coalbed methane exploration. Background Technology

[0002] Coalbed methane is an unconventional gas resource associated with and coexisting with coal. It mainly refers to hydrocarbon gases stored in coal seams, with methane as the primary component. After completing coalbed methane exploration operations, the collected samples need to be collected and stored, typically using gas cylinders and storage boxes to hold the samples. However, coalbed methane exploration sites are not all flat, open plains; some exploration locations are located in rugged terrain. When collecting coalbed methane samples in such environments, the samples are highly susceptible to falling into the rugged terrain, potentially impacting the storage container. Impacts to the storage container can also damage the internal gas cylinders, which is clearly detrimental to the proper preservation of the coalbed methane samples.

[0003] To prevent gas cylinders from accidentally impacting the storage tank after placement, the traditional method involves using clamping components to secure them. However, in some traditional storage devices, operators need to manually adjust the positions of the upper and lower clamps to bring them closer together and clamp the cylinder. Furthermore, in practice, it often happens that one clamp is engaged while the other is not, or the clamping force is inconsistent, which can cause the cylinder to tilt during storage. Therefore, overcoming these technical problems and defects is a key issue that needs to be addressed. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, which requires operators to manually adjust the positions of the upper and lower clamping parts to bring them close to and clamp the gas cylinder. In actual operation, there are often situations where one clamping part has clamped the gas cylinder while the other clamping part is not in place, or the clamping force of the two clamping parts is inconsistent. This can lead to the gas cylinder tilting during storage. The invention aims to realize a sample storage device for coalbed methane exploration.

[0005] To achieve the above-mentioned objectives, the technical solution of the present invention is: a sample storage device for coalbed methane exploration, comprising a box and a cover, wherein the cover is installed on the upper end of the box, characterized in that: mounting plates are fixedly connected to the upper and lower ends of the box, a straight toothed plate is slidably connected to the middle of the upper end of each mounting plate, a guide assembly for guiding the straight toothed plate is installed on each mounting plate, gears that mesh with the straight toothed plate are rotatably installed on both sides of each mounting plate, and clamping members for clamping gas cylinders are installed on the gears, a lead screw is rotatably installed on the inner wall of the box, and the lead screw is located between two straight toothed plates, a drive mechanism for driving the lead screw to rotate is installed on the inner wall of the box, a drive rod is threadedly connected to the lead screw, and the upper and lower ends of the drive rod are fixedly connected to the two straight toothed plates respectively.

[0006] In the above-mentioned sample storage device for coalbed methane exploration, the guiding assembly includes ear plates, guide rods and nuts. The ear plates are symmetrically fixedly connected to the mounting plate. Each ear plate is slidably connected to a guide rod through a through hole. The end of the guide rod near the straight toothed plate is fixedly connected to the straight toothed plate, and the end of the guide rod away from the straight toothed plate is threadedly connected to a nut.

[0007] In the sample storage device for coalbed methane exploration described above, the guide assembly further includes a spring, which is sleeved on the guide rod. One end of the spring is fixedly connected to the straight toothed plate, and the other end is fixedly connected to the ear plate.

[0008] In the aforementioned sample storage device for coalbed methane exploration, the clamping component includes an active connecting rod, a driven connecting rod, a movable rod, and a clamping rod. One end of the active connecting rod is fixedly connected to the upper end of a gear, and the other end is rotatably connected to a movable rod. A driven connecting rod is rotatably connected to the movable rod, and the end of the driven connecting rod away from the movable rod is rotatably connected to a mounting plate. A clamping rod for clamping the gas cylinder is fixedly connected to the movable rod.

[0009] In the aforementioned sample storage device for coalbed methane exploration, each of the clamping rods is equipped with a cushioning sponge.

[0010] In the aforementioned sample storage device for coalbed methane exploration, the drive mechanism includes a mounting frame, a drive motor, a worm gear, and a worm wheel. The mounting frame is fixedly connected to the inner wall of the housing. The worm gear is rotatably mounted on the mounting frame. The drive motor capable of driving the worm gear to rotate is mounted on the mounting frame. A worm wheel meshing with the worm gear is fixedly mounted on the lead screw.

[0011] In the sample storage device for coalbed methane exploration described above, an opening is provided in the middle of the end of the mounting plate away from the clamping member, for the drive rod to move left and right.

[0012] In the aforementioned sample storage device for coalbed methane exploration, a buffer assembly is installed at the lower end of the inner cavity of the box to cushion the gas cylinder when it is placed. The buffer assembly includes a base, round rods, a buffer plate, and elastic balls. The two ends of the buffer plate are slidably connected to the round rods through through holes. The lower end of each round rod is fixedly connected to a base, which is located at the lower end of the inner cavity of the box. An elastic ball is sleeved on each round rod, and the elastic ball is located between the base and the buffer plate.

[0013] In the sample storage device for coalbed methane exploration described above, a baffle is fixedly connected to the upper end of each of the round rods.

[0014] Compared with the prior art, the sample storage device for coalbed methane exploration of the present invention has at least the following beneficial effects: 1. The sample storage device for coalbed methane exploration of the present invention, through the ingenious design of a straight toothed plate, a guide assembly, gears, a lead screw, a drive rod, and a drive mechanism, allows the upper and lower clamping members to simultaneously clamp the gas cylinder. Compared with the traditional method that requires adjusting the clamping members one by one, this device is simpler and more convenient to operate. It also effectively avoids the gas cylinder tilting during the clamping process. Furthermore, the drive mechanism adopts a worm gear and worm wheel transmission method. The worm gear and worm wheel transmission has self-locking properties, which can keep the lead screw in a fixed position when the drive motor stops rotating, thereby ensuring the stability of the position of the straight toothed plate and the clamping members, so that the gas cylinder is always reliably clamped. At the same time, this drive method has a compact structure, smooth transmission, low noise, and is easy to operate. The clamping and releasing actions of the gas cylinder can be achieved simply by controlling the forward and reverse rotation of the drive motor.

[0015] 2. The sample storage device for coalbed methane exploration of the present invention, by installing a buffer assembly at the lower end of the box, including a base, a round rod, a buffer plate and an elastic ball, allows the elastic ball to absorb the impact force when the gas cylinder is placed on the buffer plate, thus playing a buffering role, reducing the hard collision between the gas cylinder and the bottom of the box, and further protecting the gas cylinder from damage. At the same time, the baffle restricts the movement range of the buffer plate, preventing the buffer plate from moving excessively and detaching from the round rod. Attached Figure Description

Detailed Implementation

[0018] The sample storage device for coalbed methane exploration of the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0019] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] This embodiment discloses a sample storage device for coalbed methane exploration. Through the ingenious design of the straight toothed plate 3, guide assembly 7, gear 4, lead screw 9, drive rod 8, and drive mechanism 10, the upper and lower clamping members 5 can simultaneously clamp the gas cylinder 6. Compared to the traditional method that requires adjusting each clamping member 5 individually, this device is simpler and more convenient to operate; it also effectively prevents the gas cylinder 6 from tilting during clamping. (Refer to...) Figures 1-7The device mainly includes a housing 1 and a cover 101. The cover 101 is installed on the upper end of the housing 1. The device is characterized in that: the upper and lower ends of the housing 1 are respectively fixedly connected to the mounting plates 2. Each mounting plate 2 has a slidably connected straight toothed plate 3 at the middle of its upper end. Each mounting plate 2 is equipped with a guide component 7 that can guide the straight toothed plate 3. Gears 4 that can mesh with the straight toothed plate 3 are rotatably installed on both sides of each mounting plate 2. Clamping parts 5 that can clamp the gas cylinder 6 are installed on the gears 4. A lead screw 9 is rotatably installed on the inner wall of the housing 1 and is located between two straight toothed plates 3. A drive mechanism 10 that can drive the lead screw 9 to rotate is installed on the inner wall of the housing 1. A drive rod 8 is threadedly connected to the lead screw 9. The upper and lower ends of the drive rod 8 are respectively fixedly connected to two straight toothed plates 3.

[0021] In this embodiment, refer to Figure 1 , Figure 4 , Figure 6 and Figure 7 The guide assembly 7 includes ear plates 701, guide rods 702, and nuts 703. The ear plates 701 are symmetrically fixedly connected to the mounting plate 2. Each ear plate 701 is slidably connected to a guide rod 702 through a through hole. The end of the guide rod 702 near the straight toothed plate 3 is fixedly connected to the straight toothed plate 3, and the end of the guide rod 702 away from the straight toothed plate 3 is threadedly connected to the nut 703. In actual use, the ear plates 701, guide rods 702, and nuts 703 can guide and limit the straight toothed plate 3, effectively preventing the straight toothed plate 3 from deviating during movement.

[0022] In this embodiment, refer to Figure 1 , Figure 4 , Figure 6 and Figure 7 The guide assembly 7 also includes a spring 704, which is sleeved on the guide rod 702. One end of the spring 704 is fixedly connected to the straight tooth plate 3, and the other end is fixedly connected to the ear plate 701. Through the spring 704, after the gas cylinder 6 is clamped, the elastic tension of the spring 704 can provide a continuous clamping force to the clamping member 5, ensuring that the clamping member 5 always fits tightly against the surface of the gas cylinder 6, enhancing the stability of the clamping. Even if the drive rod 8 breaks accidentally, the elasticity of the spring 704 can still provide a certain degree of buffering and stabilization, preventing the gas cylinder 6 from falling off due to loose clamping, and ensuring the safety of the coalbed methane sample during storage and transportation.

[0023] In this embodiment, refer to Figure 1 , Figure 4 , Figure 6 and Figure 7The clamping component 5 includes an active connecting rod 501, a driven connecting rod 502, a movable rod 503, and a clamping rod 504. One end of the active connecting rod 501 is fixedly connected to the upper end of the gear 4, and the other end is rotatably connected to the movable rod 503. The driven connecting rod 502 is rotatably connected to the movable rod 503. The end of the driven connecting rod 502 away from the movable rod 503 is rotatably connected to the mounting plate 2. The clamping rod 504, which can clamp the gas cylinder 6, is fixedly connected to the movable rod 503. In actual use, when the gear 4 rotates, the clamping rod 504 can clamp the gas cylinder 6 through the clever cooperation of the active connecting rod 501, the driven connecting rod 502, the movable rod 503, and the clamping rod 504.

[0024] In this embodiment, each of the clamping rods 504 is equipped with a buffer sponge. The buffer sponge further enhances the protection of the gas cylinder 6. The buffer sponge not only increases the friction between the clamping rod 504 and the gas cylinder 6, but also plays a buffering role during the clamping process, avoiding direct hard contact between the clamping rod 504 and the surface of the gas cylinder 6, effectively protecting the appearance and internal structure of the gas cylinder 6, and ensuring the integrity of the sample.

[0025] In this embodiment, refer to Figure 1 , Figure 2 and Figure 4 The drive mechanism 10 includes a mounting frame 1001, a drive motor 1002, a worm gear 1003, and a worm wheel 1004. The mounting frame 1001 is fixedly connected to the inner wall of the housing 1. The worm gear 1003 is rotatably mounted on the mounting frame 1001. The drive motor 1002, which can drive the worm gear 1003 to rotate, is mounted on the mounting frame 1001. The worm wheel 1004, which meshes with the worm gear 1003, is fixedly mounted on the lead screw 9. In actual use, the drive motor 1002 is started, which drives the worm gear 1003 to rotate. The worm gear 1003 meshes with the worm wheel 1004, causing the worm wheel 1004 to rotate. The worm wheel 1004 drives the lead screw 9 to rotate.

[0026] In this embodiment, refer to Figure 1 , Figure 4 , Figure 6 and Figure 7 The mounting plate 2 has an opening 201 at the center of the end away from the clamping member 5, which is used to allow the drive rod 8 to move left and right. The opening 201 allows the drive rod 8 to slide within the opening 201, effectively avoiding interference during the movement of the drive rod 8.

[0027] In this embodiment, refer to Figure 1 and Figure 4The lower interior of the housing 1 is equipped with a buffer assembly 11 for cushioning the placement of the gas cylinder 6. The buffer assembly 11 includes a base 1101, a round rod 1102, a buffer plate 1103, and an elastic ball 1104. The two ends of the buffer plate 1103 are slidably connected to the round rod 1102 through through holes. The lower end of each round rod 1102 is fixedly connected to the base 1101. The base 1101 is located on the lower interior of the housing 1. An elastic ball 1104 is sleeved on each round rod 1102. The elastic ball 1104 is located between the base 1101 and the buffer plate 1103. In practical use, when the gas cylinder 6 is placed on the buffer plate 1103, the elastic ball 1104 can absorb the impact force when the gas cylinder 6 falls, play a buffering role, reduce the hard collision between the gas cylinder 6 and the bottom of the box 1, and further protect the gas cylinder 6 from damage.

[0028] In this embodiment, refer to Figure 1 and Figure 4 Each of the round rods 1102 has a baffle 1105 fixedly connected to its upper end; the baffle 1105 can block the buffer plate 1103, thereby effectively preventing the buffer plate 1103 from detaching from the round rod 1102.

[0029] The working principle of the sample storage device for coalbed methane exploration of the present invention is as follows: After the exploration sample is stored in the gas cylinder 6, the cover 101 is opened, and the gas cylinder 6 is placed on the buffer plate 1103 inside the box 1. The drive motor 1002 is controlled, and the drive motor 1002 drives the lead screw 9 to rotate. The lead screw 9 drives the drive rod 8 to rotate. However, under the limitation of the straight tooth plate 3 and the guide assembly 7, the drive rod 8 moves left and right. The drive rod 8 drives the straight tooth plate 3 to move left and right. The straight tooth plate 3 meshes with the gears 4 on both sides, causing the gears 4 to rotate. With the cooperation of the active connecting rod 501, the driven connecting rod 502, the movable rod 503 and the clamping rod 504, the clamping rod 504 clamps the gas cylinder 6, thereby effectively preventing the gas cylinder 6 from colliding with the inner wall of the box 1 and causing damage to the gas cylinder 6 when the box 1 is accidentally impacted.
