Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, and in particular to a submersible sampling device. Background Technology

[0002] When coal is loaded onto bituminous coal cars and enters the plant, it may stratify due to vibration and bumps at different depths during transportation, resulting in variations in particle size and composition. To understand the quality of coal at different depths on the bituminous coal cars, it is necessary to perform stratified sampling and testing. Common sampling methods include manual sampling and mechanical sampling. Manual sampling is greatly affected by human factors and the representativeness of the samples is insufficient. Mechanical sampling is more efficient and saves labor intensity. Common mechanical sampling devices insert a sampling cylinder into the coal pile inside the bituminous coal car and then use a spiral auger inside the sampling cylinder to take samples, which is convenient and quick.

[0003] However, in mechanical sampling, when it is necessary to sample coal at different depths, the sampling tube needs to be lowered to different depths multiple times to take individual samples, and then the sampled coal can be released before sampling coal at the next depth can be carried out, which is a rather troublesome operation.

[0004] Therefore, based on the above situation, it is necessary to design a submersible sampling device to solve the above problems. Utility Model Content

[0005] This invention provides a submersible sampling device to solve the problems in the prior art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A submersible sampling device includes a sampling mechanism capable of submerging into a coal pile. The sampling mechanism includes an outer sampling barrel and an inner sampling barrel movably connected inside the outer sampling barrel. The inner sampling barrel has multiple sampling chambers arranged along its axial direction. Both the inner and outer sampling barrels have inlets for feeding material into the sampling chambers. When the inlets on the inner and outer sampling barrels are aligned, coal enters the sampling chambers through the inlets, enabling individual sampling of coal at different depths. Both the inner and outer sampling barrels have outlets for discharging material from the sampling chambers. When the outlets on the inner and outer sampling barrels are aligned, material from the multiple sampling chambers is discharged individually.

[0008] Preferably, the upper part of the sampling outer barrel is provided with a motor whose output end is connected to the sampling inner barrel. When the motor drives the sampling inner barrel to rotate, it is used to align or misalign the feed port on the sampling inner barrel with the feed port on the sampling outer barrel.

[0009] Preferably, the motor is provided with a flat plate, and a first telescopic member is provided between the flat plate and the outer sampling barrel. When the first telescopic member drives the inner sampling barrel to move up and down, it is used to align or misalign the discharge port on the inner sampling barrel with the discharge port on the outer sampling barrel.

[0010] Preferably, it also includes a gantry frame, which is connected to the outer sampling bucket via a second telescopic member. When the second telescopic member lowers the outer sampling bucket, it is used to submerge the outer sampling bucket and the inner sampling bucket into the coal pile.

[0011] Preferably, the inner bottom surface of the sampling chamber is inclined downward from the inlet direction to the outlet direction.

[0012] Preferably, the gantry frame is provided with multiple guide plates with their output ends inclined downwards, and the input ends of the multiple guide plates correspond to the discharge ports on the multiple sampling chambers respectively.

[0013] The beneficial effects of this utility model are as follows: after the outer sampling barrel and the inner sampling barrel are submerged into the coal pile to a certain depth, the feed inlet on the outer sampling barrel is aligned with the feed inlet on the inner sampling barrel. At this time, multiple sampling chambers are opened, and coal at different depths corresponding to each sampling chamber will enter the sampling chamber and be collected. Finally, the discharge outlet on the outer sampling barrel is aligned with the discharge outlet on the inner sampling barrel for simultaneous discharge. The operation process is simple and the sampling efficiency is improved. Attached Figure Description

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] Reference Figures 1-5 As shown, a submersible sampling device includes a sampling mechanism 1 that can submerge into the interior of a coal pile. The sampling mechanism 1 includes an outer sampling barrel 11 and an inner sampling barrel 12 movably connected inside the outer sampling barrel 11. When the inner sampling barrel 12 and the outer sampling barrel 11 are inserted into the coal pile on a bituminous coal car, multiple sampling chambers 2 are provided along their axial direction inside the inner sampling barrel 12 to sample coal at different depths individually. Both the inner sampling barrel 12 and the outer sampling barrel 11 have inlets 3. The inner sampling barrel 12 is then rotated so that its inlet 3 aligns with the inlet 3 on the outer sampling barrel 11. At this time, each sampling chamber 2 opens, and coal at the corresponding depth of each sampling chamber 2 enters the interior of the sampling chamber 2 through the inlet 3. To prevent the outer sampling barrel 12 from being submerged into the coal pile, the sampling mechanism 1 is designed to prevent the coal at different depths from being sampled individually. Material enters between the sampling inner barrel 11 and the sampling outer barrel 12. The inner wall of the sampling outer barrel 11 is attached to the outer wall of the sampling inner barrel 12. Then, the sampling inner barrel 12 is rotated so that the sampling outer barrel 11 is misaligned with the feed port 3 on the sampling inner barrel 12, thus blocking the feed port 3. This prevents coal at other depths from interfering with the coal in the sampling chamber 2 when the sampling mechanism 1 is pulled up, enabling separate sampling of coal at different depths. After the sampling mechanism 1 leaves the coal pile, the discharge port 4 on the sampling inner barrel 12 is aligned with the discharge port 4 on the sampling outer barrel 11. At this time, the sampling chamber 2 is opened, and the material in each sampling chamber 2 is collected separately. By performing layered sampling of the coal on each bituminous coal car, the operation is not only quick and simple, but also allows for accurate understanding of the coal quality at different depths on the bituminous coal car.

[0023] Reference Figure 3As shown, furthermore, to facilitate opening or closing the feed inlet 3, a motor 5 with an output end connected to the sampling inner barrel 12 is provided above the sampling outer barrel 11. Before entering the coal pile, the feed inlet 3 on the sampling outer barrel 11 and the feed inlet 3 on the sampling inner barrel 12 are in a left-right misaligned state, and the feed inlet 3 is closed at this time. When the sampling mechanism 1 dives into the coal pile, the motor 5 is started, and the motor 5 drives the sampling inner barrel 12 to rotate, so that the feed inlet 3 on the sampling inner barrel 12 is aligned with the feed inlet 3 on the sampling outer barrel 11, thereby realizing the sampling of materials. After the sampling is completed, the motor 5 drives the sampling inner barrel 12 to rotate in the opposite direction to the initial state, so that the feed inlet 3 on the sampling inner barrel 12 is misaligned with the feed inlet 3 on the sampling outer barrel 11. When the sampling mechanism 1 is pulled out of the coal pile, it can prevent coal at other depths from mixing with the sampled coal.

[0024] Reference Figure 4 As shown, furthermore, in order to facilitate the simultaneous release of materials in sampling chamber 2, a flat plate 6 is provided on the motor 5, and a first telescopic component 7 is provided between the flat plate 6 and the sampling barrel. The first telescopic component 7 can be an electric telescopic rod, an electric push rod, or other devices. Similarly, before the sampling mechanism 1 descends into the coal pile, the discharge port 4 on the inner sampling barrel 12 and the discharge port 4 on the outer sampling barrel 11 are in a vertically staggered state. The vertically staggered discharge port 4 can be in a blocked state when the inlet 3 is aligned. After sampling is completed, the first telescopic component 7 drives the flat plate 6 to move upward, and at the same time drives the motor 5 and the inner sampling barrel 12 to move upward. When the inner sampling barrel 12 contacts the inner top surface of the outer sampling barrel 11, the discharge port 4 on the inner sampling barrel 12 is aligned with the discharge port 4 on the outer sampling barrel 11. At this time, the sampling chambers 2 open simultaneously, realizing the simultaneous individual collection of materials in multiple sampling chambers 2.

[0025] Reference Figures 1-4 As shown, furthermore, for ease of use, a gantry frame 8 is also included. The gantry frame 8 is connected to the sampling outer barrel 11 via a second telescopic component 9. The second telescopic component 9 can also be an electric telescopic rod, an electric push rod, or other devices. In actual use, to improve the flexibility of use, telescopic structures and pulleys can also be installed on both sides of the bottom of the gantry frame 8. It can also be directly erected and fixed on the ground. When the coal car enters the plant, it passes directly through the bottom of the gantry frame 8, and then the second telescopic component 9 drives the sampling mechanism 1 to descend, submerging the sampling mechanism 1 into the coal pile. This allows for efficient docking with the coal car and convenient sampling.

[0026] Reference Figure 3 , Figure 4As shown, furthermore, in order to facilitate material discharge, the inner bottom surface of the sampling chamber 2 is inclined downward from the direction of the feed inlet 3 to the direction of the discharge outlet 4. The inclined bottom surface helps to prevent coal from accumulating and clogging at the discharge outlet 4. Since the coal will naturally slide down the inclined surface, it is not easy to accumulate at the discharge outlet 4, thereby ensuring the continuity of the discharge process, reducing the need for manual unblocking due to blockage, and improving the discharge efficiency.

[0027] Reference Figures 1-5 As shown, furthermore, in order to facilitate the separate collection of materials in the sampling chamber 2, the gantry 8 is provided with multiple guide plates 10. The input ends of the multiple guide plates 10 correspond to the discharge ports 4 on the multiple sampling chambers 2 respectively. Each guide plate 10 corresponds to the discharge port 4 of one sampling chamber 2, which can ensure that the coal samples in different sampling chambers 2 are collected separately, avoid sample confusion, and ensure the independence and integrity of each sample. This provides a basis for subsequent separate analysis and testing of coal samples at different depths. In order to make the guide plate 10 stick to the sampling outer barrel 11 and prevent the material from spilling between the two, the input end of the guide plate 10 is slidably set with the sampling outer barrel 11.
