Description

Technical Field

[0001] The present invention belongs to the technical field of mining area gas detection equipment, and in particular relates to a gas sampling mechanical arm for mining area ecological restoration and carbon sink assessment. Background Art

[0002] Gas sampling for carbon sink assessment in mining area ecological restoration involves using specialized equipment to collect greenhouse gases (such as CO2 and CH4) from the soil, vegetation, and atmosphere within the restoration area. This process aims to quantify the impact of ecological restoration on carbon sequestration capacity. Sampling must cover different terrains (such as subsidence areas and slopes) and restoration stages. Using both fixed-point and dynamic monitoring methods, data such as gas concentrations and fluxes can be acquired to analyze the relationship between changes in carbon reserves and the effectiveness of ecological restoration. The gas sampling robotic arm for carbon sink assessment in mining area ecological restoration is an intelligent device specifically designed for mining area ecological restoration scenarios. It integrates high-precision gas sensors, a multi-degree-of-freedom robotic arm, and an environmental perception module to automatically sample greenhouse gases (such as CO2 and CH4) above soil and vegetation in mining areas.

[0003] At present, the commonly used gas sampling method for carbon sink assessment in ecological restoration of mining areas mainly relies on a robotic arm to manipulate the sampler to insert it into a pre-drilled detection hole to collect gas samples from the subsurface layer. However, this method has obvious limitations in actual operation. When repeated sampling of the same location is required, a new storage tank must be manually replaced after each sampling. This not only increases the operating steps and complexity of the robotic arm, but also easily leads to positioning deviation or excessive time consumption due to frequent movements, affecting sampling efficiency and data continuity.

[0004] To this end, we provide a gas sampling robotic arm for mining area ecological restoration and carbon sink assessment to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a gas sampling robotic arm for carbon sink assessment in mining area ecological restoration. Through the cooperation of storage components, adjustment components and negative pressure components, it solves the problem of the commonly used gas sampling method in mining area ecological restoration carbon sink assessment in the prior art, in which a new storage tank must be manually replaced after each sampling, which increases the operation steps of the robotic arm.

[0006] To solve the above technical problems, the present invention is implemented through the following technical solutions.

[0007] The present invention is a gas sampling robotic arm for carbon sink assessment of ecological restoration in mining areas, comprising a base, a driving arm mounted on the top of the base, a storage seat mounted on the top of the base, a sampling shell arranged inside the storage seat; a storage assembly is arranged inside the sampling shell, the storage assembly comprises a fixed plate mounted inside the sampling shell, a support tube fixedly connected to the inside of the fixed plate, a storage bag connected to the top of the support tube, and gas samples are stored in groups through the storage assembly; an adjustment assembly is arranged inside the sampling shell, the adjustment assembly comprises a rotating shaft movably connected to the inside of the fixed plate, a disc mounted on the surface of the rotating shaft, a card slot opened on one side of the disc, an inclined groove opened inside the card slot, a sealing plug slidably connected to the inside of the support tube, and a ventilation groove opened inside the sealing plug; a negative pressure assembly is arranged on one side of the driving arm, the negative pressure assembly comprises a connecting shell mounted on the output end of the driving arm, a negative pressure pump mounted on one side of the connecting shell, and an air intake pipe connected to one side of the negative pressure pump, and negative pressure is provided to the inside of the sampling shell through the negative pressure assembly.

[0008] The present invention is further configured such that the adjustment assembly also includes a drive motor installed on the top of the fixed plate, a reset disk installed on the surface of the sealing plug, and a first spring sleeved on the surface of the sealing plug.

[0009] The present invention is further configured such that the output of the driving motor is fixedly connected to the disc, and one end of the first spring is fixedly connected to the reset disc.

[0010] The present invention is further configured such that a connecting assembly is provided on the top of the sampling shell, the connecting assembly includes a sealing shell threadedly connected to the top of the sampling shell, a square tube installed on the top of the sealing shell, and a sealing disk slidably connected to the surface of the square tube.

[0011] The present invention is further configured such that the connecting assembly further includes a connecting hole opened inside the square tube, a second spring sleeved on the surface of the square tube, and a limit block installed on the top of the square tube.

[0012] The present invention is further configured such that an electric push rod is installed inside the connecting shell, and a clamping plate is fixedly connected to an output end of the electric push rod.

[0016] The present invention is further configured such that the storage bag is made of an aluminum foil composite film, and the disc is arranged between the support tube and the reset disc.

[0017] The present invention has the following beneficial effects.

The storage component adopts four groups of aluminum foil composite film storage bags, and cooperates with the disc structure driven by the rotating shaft to realize automatic grouping and storage of gas samples in multiple time periods at the same sampling position, avoiding the need for traditional robotic arms to frequently replace storage tanks, and solving the positioning deviation problem caused by manual intervention. The adjustment component drives the disc to rotate through the driving motor, so that the inclined groove and the sealing plug are accurately aligned, and the storage bag can be quickly switched under the action of negative pressure.

[0019] 2. The present invention optimizes the sealing and operational convenience of the sampling process through the arrangement of a negative pressure component and a connecting component. The negative pressure component uses an electric push rod to clamp and fix the sampling shell, and forms a closed airflow channel through the suction pipe and the connecting hole. With the cooperation of the sealing plug ventilation groove, the timing of the gas flowing into the storage bag is accurately controlled, avoiding the risk of sample contamination caused by air pressure fluctuations in traditional sampling. The connecting component realizes quick plug-in and pull-out sealing through the sealing disk and the second spring built into the square tube, thereby improving the adaptability and operation continuity of the equipment in the complex terrain of the mining area.

[0030] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1

[0031] See also Figure 1-Figure 7 The present invention is a gas sampling robot arm for carbon sink assessment of ecological restoration in mining areas, comprising a base 1, a driving arm 2 mounted on the top of the base 1, a storage seat 3 mounted on the top of the base 1, a sampling shell 4 arranged inside the storage seat 3; a storage assembly is arranged inside the sampling shell 4, the storage assembly comprises a fixing plate 5 mounted inside the sampling shell 4, a support tube 6 fixedly connected to the inside of the fixing plate 5, a storage bag 7 connected to the top of the support tube 6, and gas samples are stored in groups through the storage assembly; an adjustment assembly is arranged inside the sampling shell 4, the adjustment assembly comprises a movable connection A rotating shaft 8 is inside the fixed plate 5, a disc 9 is installed on the surface of the rotating shaft 8, a slot 10 is opened on one side of the disc 9, an inclined slot 11 is opened inside the slot 10, a sealing plug 12 is slidably connected to the inside of the support tube 6, and a ventilation groove 13 is opened inside the sealing plug 12; a negative pressure component is provided on one side of the driving arm 2, the negative pressure component includes a connecting shell 14 installed at the output end of the driving arm 2, a negative pressure pump 15 installed on one side of the connecting shell 14, and an air intake pipe 16 connected to one side of the negative pressure pump 15, and negative pressure is provided to the inside of the sampling shell 4 through the negative pressure component.

[0032] Specifically: the driving arm 2 uses a motor and a hydraulic device as power sources, and transmits power to each joint through a transmission mechanism (such as gears and connecting rods). The control system accurately calculates the angle and speed of each joint based on a preset program or sensor feedback signal. The driving arm 2 moves along a specified trajectory and can drive the sampling shell 4 to move. This is an existing mature technical application. The sampling tube 28 is buried in the gas sampling hole in the mining area. The sampling hole 29 is used for the circulation of gas inside the sampling tube 28. During sampling, the sampling shell 4 is driven by the driving arm 2 to insert into the sampling tube 28. Example 2

[0033] See also Figure 1-Figure 7 On the basis of Example 1, the adjustment component also includes a drive motor 17 installed on the top of the fixed plate 5, a reset disk 18 installed on the surface of the sealing plug 12, and a first spring 19 sleeved on the surface of the sealing plug 12. The output of the drive motor 17 is fixedly connected to the disc 9, and one end of the first spring 19 is fixedly connected to the reset disk 18. A connecting component is provided on the top of the sampling shell 4, and the connecting component includes a sealing shell 20 threadedly connected to the top of the sampling shell 4, a square tube 21 installed on the top of the sealing shell 20, and a sealing disk 22 slidably connected to the surface of the square tube 21. The connecting component also includes a connecting hole 23 opened inside the square tube 21, a second spring 24 sleeved on the surface of the square tube 21, and a limit block 25 installed on the top of the square tube 21.

[0034] Specifically: the storage bag 7 is made of aluminum foil composite film and has a certain elasticity. When the interior of the sampling shell 4 is in a negative pressure state, external gas can enter the storage bag 7 through the support tube 6 to achieve the function of extracting gas samples. There are four groups of storage bags 7, and the four groups of storage bags 7 are all arranged in the sampling shell 4. When the driving arm 2 drives the sampling shell 4 to move to the gas sampling hole in the mining area, gas samples of four time periods can be collected, thereby improving the efficiency of gas sampling. Example 3

[0035] See also Figure 1-Figure 7 On the basis of Examples 1 and 2, an electric push rod 26 is installed inside the connecting shell 14, and a clamping plate 27 is fixedly connected to the output end of the electric push rod 26. A sampling tube 28 is provided on one side of the base 1, and a sampling hole 29 is provided inside the sampling tube 28. A placement hole 30 is opened inside the storage seat 3, and the sealing disk 22 is slidably connected to the inner wall of the placement hole 30. An exhaust pipe 31 is connected to the top of the storage bag 7, and a sealing cover 32 is threadedly connected to the surface of the exhaust pipe 31. The storage bag 7 is made of aluminum foil composite film, and the disc 9 is arranged between the support tube 6 and the reset disk 18.

[0036] Specifically: the disc 9 is arranged between the support tube 6 and the reset disc 18, and the disc 9 can limit the movement of the reset disc 18 to prevent the reset disc 18 from moving upward. The first spring 19 and the second spring 24 both have the function of compressing energy storage. The first spring 19 can reset the reset disc 18, move the sealing plug 12 downward, and seal the ventilation groove 13 through the inner wall of the support tube 6. The second spring 24 can reset the square tube 21 and use the inner wall of the sealing disc 22 to seal the connecting hole 23.

[0037] The working principle of the present invention is: when collecting gas for ecological restoration in a mining area, it is necessary to detect the gas sampling position in advance, dig a sampling hole, and bury the sampling tube 28 in the sampling hole to concentrate the gas out. Then, the base 1 is installed to one side of the sampling hole, and the drive arm 2 is started.

[0038] The driving arm 2 drives the connecting shell 14 to move, so that the bottom of the connecting shell 14 contacts the sealing disk 22 and pushes the sealing disk 22 downward. Figure 7 As shown, when the sealing disk 22 moves, the seal on the connecting hole 23 is cancelled and the second spring 24 is squeezed. Then, the connecting shell 14 is moved downward to keep the connection shell 14 and the sealing disk 22 airtight. The electric push rod 26 is started, and the electric push rod 26 drives the clamping plate 27 to move, contact the square tube 21, and clamp the square tube 21 to fix the sampling shell 4. Then, the driving arm 2 is started to drive the sampling shell 4 to be inserted into the sampling tube 28.

[0039] Afterwards, the connecting shell 14 and the sampling shell 4 are connected through the connecting hole 23, and the negative pressure pump 15 is started. The negative pressure pump 15 uses the suction pipe 16 and the connecting hole 23 to extract the gas inside the sampling shell 4, generating negative pressure. Under the action of the negative pressure, the sealing plug 12 will move upward and squeeze the first spring 19. At this time, the ventilation groove 13 is connected to the external environment and the support tube 6, and the external gas is drawn into the storage bag 7 for storage by the action of negative pressure, thereby achieving the effect of rapid sampling.

[0040] When secondary sampling is required at the current position, the drive motor 17 can be started, and the drive motor 17 drives the disc 9 to rotate so that the card slot 10 is aligned with the next group of sealing plugs 12. Under the action of negative pressure, the sealing plug 12 at the current position can move upward and enter the next group of storage bags 7 through the ventilation groove 13 to achieve secondary sampling and storage, realizing the effect of multiple sampling at the same position in different time periods, and improving the gas sampling efficiency.

[0041] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
