Description

Technical Field

[0001] The present invention relates to the technical field of substations, and particularly to a soil sampling device. Background Art

[0002] The main components of a transformer are the primary coil, secondary coil, and iron core. In electrical equipment and radio circuits, it is commonly used for stepping up or down voltage, impedance matching, safety isolation, etc. During the operation of existing transformers, their interiors are often in a continuously heating state, which may cause spontaneous combustion over a long time. To determine the specific cause of transformer combustion and prevent similar accidents, after the transformer combustion is extinguished using fire extinguishing agents such as water spray, aqueous film-forming foam, and carbon dioxide, it is necessary to sample and detect the soil after combustion. Moreover, soil sampling needs to be carried out separately at different locations. Most soil sampling devices on the market need to perform processes such as soil extraction, soil pushing, and collection. However, general sampling devices have too low automation and waste a great deal of time. Therefore, it is very necessary to propose a soil sampling device for substation classification storage.

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a soil sampling device, which has the following beneficial effects:

[0021] 1. The present invention provides overall support by setting a bottom plate, and then starts the fixing and protection functions by setting a support frame. The cylinder can be used to facilitate the cylinder to push the soil shovel out of the gap to sample the soil. At the same time, the soil withdrawal device cooperates with the collection device to withdraw the soil sampled by the soil shovel and collect it through the collection device, thereby achieving a high degree of sampling automation, improving efficiency, and reducing the manpower burden.

[0022] 2. The soil discharging device of the present invention uses the cooperation of the first magnet and the second magnet. When the air cylinder is started, the air cylinder pushes the soil sampling shovel downward. The soil sampling shovel passes through the notch to sample the soil. During the sampling process, the soil will squeeze the soil pushing plate upward and compress the compression spring. At the same time, the soil pushing plate drives the convex rod upward, so that the wedge block is engaged with the second card slot to fix the position of the soil pushing plate. Then, the air cylinder is started to contract. The air cylinder drives the soil sampling shovel upward, and the soil sampling shovel drives the convex block upward. During the movement of the convex block, it will contact the pressing block. When the convex block moves to the position of the inclined opening on the partition plate, the convex block will lift the pressing block. At the same time, the partition plate will move under the action of the first spring. At this time, the baffle no longer blocks the swing frame, and at the same time, the sliding frame will move under the action of the first tension spring, so that the sliding frame is disengaged from the first card slot. At the same time, the push plate will push the storage box to move under the action of the second spring, and push the storage box onto the carrier plate. At this time, the partition plate will block the storage box from continuing to move. At this time, the air cylinder drives the soil sampling shovel to continue to move upward. When the soil sampling shovel moves to a certain position, the first magnet will adsorb the second magnet to move and stretch the second tension spring, so that the wedge block is disengaged from the second card slot. At this time, the soil pushing plate will move downward under the action of the compression spring, and push the soil out of the soil sampling shovel and fall into the storage box. It can realize the automatic soil discharging in the soil sampling shovel without manual operation, saving time.

[0023] 3. Through the arrangement of the ball bearings in the present invention, when the storage box moves along the inclined groove into the installation groove, the storage box will continue to move in the installation groove for a certain distance through the ball bearings, so as to provide a position for the subsequent storage box, facilitating the sequential loading of the sampled soil in each storage box, improving the efficiency and having a good use effect.

[0024] 6. Through the cooperation of the sliding frame and the first card slot in the present invention, when the front storage box is full of soil and moves along the inclined groove, the sliding frame will block the first card slot to prevent the subsequent storage box from moving forward, causing unnecessary trouble and improving the convenience of using the device.

[0025] 9. Through the arrangement of the sealing gasket in the present invention, after the storage box is full of soil, the pressing block will contact the storage box. At this time, the sealing gasket can seal the gap between the pressing block and the storage box, so as to better preserve the soil.

[0026] 12. Through the arrangement of the moving wheels in the present invention, when sampling soils of different geological conditions, it is necessary to move to another place. At this time, the staff can push the device through the moving wheels, facilitating the staff to move the position of the device and improving the convenience of using the device.

The swing frame 17 is rotatably connected to the frame and includes a first end and a second end located on both sides of the rotation point. The first end cooperates with the shielding component, and the second end cooperates with the sliding frame 18. When the shielding component resists the first end of the swing frame 17 under the action of the soil sampling shovel 16, the second end of the swing frame 17 is used to resist the sliding frame 18 so that the sliding frame 18 is clamped with the first card slot 7 of the storage box 6.

[0052] Furthermore, the sealing assembly includes a first positioning column 12 fixed to the top inner wall of the frame, the circumferential outer wall of the first positioning column 12 is movably connected with a pressure block 10, and the protrusion 14 is in contact with the pressure block 10, the bottom end of the first positioning column 12 is fixedly connected with a first baffle 11, the bottom of the pressure block 10 is fixedly connected with a sealing gasket 9, and the sealing gasket 9 is in contact with the storage box 6.

[0053] Furthermore, a plurality of balls 25 are provided in the installation groove, and the storage box 6 can slide in cooperation with the balls 25 .

[0054] Working principle of this embodiment: When in use, the cylinder 15 is started, and the cylinder 15 pushes the soil shovel 16 to move downward, and the soil shovel 16 passes through the notch on the bottom plate 4 to sample the soil;

[0055] During the sampling process, the soil will squeeze the bulldozer 40 to move upward and squeeze the compression spring 39 along the inner length direction of the soil shovel 16. At the same time, the bulldozer 40 drives the convex rod 41 to move upward, so that the wedge block 43 is engaged with the second slot 42, and the upward position of the bulldozer 40 is limited.

[0056] Then, the cylinder 15 is started to contract, and the cylinder 15 drives the earth shovel 16 to move upward, and the earth shovel 16 drives the protrusion 14 to move upward. During the movement of the protrusion 14, it will abut against the bottom wall of the upper plate of the pressing block 10, and drive the pressing block 10 to move upward synchronously. When the protrusion 14 moves to the position of the oblique opening 46 on the partition 13, the protrusion 14 is separated from the partition 13; at the same time, the partition 13 is moved in the direction close to the earth shovel 16 by the force of the first spring 23, and at this time, the partition 13 is separated from the first end of the swing frame 17;

[0057] Among them, the middle part of the swing frame 17 is rotationally connected to the bottom plate 4 through a pin shaft. One end of the swing frame 17 contacts the partition plate 13, and the other end is hinged to the carriage 18. Therefore, when the swing frame 17 is pushed by the partition plate 13, the carriage 18 can be driven to slide at the other end of the swing frame 17, realizing the engagement or disengagement of the carriage 18 with the first card slot 7;

[0058] At the same time, the carriage 18 moves in the direction of contraction of the first tension spring 19 under the action of the first tension spring 19, and then disengages from the first card slot 7 of the storage box 6. The push plate 27 will push the storage box 6 in the direction of the groove 34 under the action of the second spring 28, and push the storage box 6 onto the carrier plate 35. At this time, the partition plate 13 will block the storage box 6 from continuing to move;

[0059] Then, the air cylinder 15 drives the soil shovel 16 to continue moving upward. When the soil shovel 16 moves to the position where the second magnet 44 corresponds to the first magnet 36, the first magnet 36 will adsorb the second magnet 44 and move it away from the soil shovel 16 and stretch the second tension spring 45, so that the wedge block 43 disengages from the second card slot 42; At this time, the earth pushing plate 40 will move downward under the action of the compression spring 39, push the soil out of the soil shovel 16, and drop it into the storage box 6;

[0060] Then, the air cylinder 15 is started to extend, and the air cylinder 15 drives the soil shovel 16 to move downward, so that the first magnet 36 and the second magnet 44 are disengaged from adsorption; When the soil shovel 16 moves to a certain position, the convex block 14 will contact the partition plate 13 and push the partition plate 13 to move away from the soil shovel 16. At this time, the partition plate 13 no longer blocks the storage box 6, and the storage box 6 presses the carrier plate 35 downward under its own gravity, so that the carrier plate 35 presses the third spring 33. At the same time, the storage box 6 will move along the inclined groove 26 to the installation groove;

[0061] At the same time, the partition plate 13 contacts the first end of the swing frame 17, causing the swing frame 17 to rotate around the pin shaft, so that the second end of the swing frame 17 pushes the carriage 18 to move and stretch the first tension spring 19, so that the carriage 18 contacts the first card slot 7 again and locks the storage box 6;

[0062] Finally, the pressing block 10 moves downward under its own gravity. When the soil shovel 16 drives the convex block 14 to completely disengage from the pressing block 10, the pressing block 10 will contact the storage box 6 and seal the storage box 6 through the sealing gasket 9.

[0063] In this embodiment, the soil discharging device uses the first magnet 36 and the second magnet 44 in cooperation to start the cylinder 15. The cylinder 15 pushes the soil sampling shovel 8 downward, and the soil sampling shovel 8 passes through the notch to sample the soil. During the sampling process, the soil will squeeze the soil pushing plate 40 upward and compress the compression spring 39. At the same time, the soil pushing plate 40 drives the convex rod 41 upward, so that the wedge-shaped block 43 is engaged with the second card slot 42 to fix the position of the soil pushing plate 40. Then, the cylinder 15 is started to contract, and the cylinder 15 drives the soil sampling shovel 8 upward. The soil sampling shovel 8 drives the convex block 14 upward. During the movement of the convex block 14, it will contact the pressing block 10. When the convex block 14 moves to the position of the inclined opening 46 on the partition plate 13, the convex block 14 will lift the pressing block 10. At the same time, the partition plate 13 will move under the action of the first spring. At this time, the baffle plate no longer blocks the swing frame 17, and at the same time, the sliding frame 18 will move under the action of the first tension spring 19, so that the sliding frame 18 is disengaged from the first card slot 3. At the same time, the push plate 27 will push the storage box 9 to move through the action of the second spring, and push the storage box 9 onto the carrier plate. At this time, the partition plate 13 will block the storage box 9 from continuing to move. At this time, the cylinder 15 drives the soil sampling shovel 8 to continue to move upward. When the soil sampling shovel 8 moves to a certain position, the first magnet 36 will adsorb the second magnet 44 to move and stretch the second tension spring 45, so that the wedge-shaped block 43 is disengaged from the second card slot 42. At this time, the soil pushing plate 40 will move downward through the action of the compression spring 39 to push the soil out of the soil sampling shovel 8 and fall into the storage box 9, realizing the automatic soil discharging in the soil sampling shovel 8 without manual operation, saving time;

[0064] At the same time, through the setting of the sealing gasket 9, after the storage box 9 is filled with soil, the pressing block 10 will contact the storage box 9. At this time, the sealing gasket 9 can seal the gap between the pressing block 10 and the storage box 9, so as to better preserve the soil;

[0065] Through the cooperation of the sliding frame 18 and the first card slot 3, when the previous storage box 9 is filled with soil and moves along the inclined groove 26, the sliding frame 18 will block the first card slot 3 to prevent the subsequent storage box 9 from moving forward, causing unnecessary trouble and improving the convenience of using the device.

[0066] In the description of this article, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
