Description

Technical Field

[0001] The present invention relates to the technical field of measuring equipment, and in particular to a field measuring equipment for power grid layout planning. Background Art

[0002] Grid cable planning survey is the process of determining and planning the layout of underground cables in the power grid.

[0003] During the field survey phase, a lot of data needs to be tested and confirmed, which requires the cooperation of multiple people. Moreover, each person needs to carry a large amount of equipment to complete various measurements and tests. The overall detection efficiency is very low, the workload of the surveyors is very heavy, and there is a certain amount of human error in the survey accuracy.

[0004] To address the above issues, Chinese invention patent CN117470312B discloses a power grid planning and measurement device. This device is highly integrated and eliminates the need for multiple personnel or for each person to carry a large amount of equipment. This effectively reduces the burden on measurement personnel and greatly improves the efficiency of power grid pole planning and construction. However, due to structural limitations, it suffers from the following deficiencies:

[0005] The first is that the soil samples taken out are incomplete (broken, left behind, dropped, etc.), which seriously affects the convenience and efficiency of measurement;

[0006] The second is that soil samples are directly discharged after measurement, making it difficult to retain them for further measurement and archiving;

[0007] Third, if you want to retain the sample, you need to drain it into the soil sample on the ground and take another sample. It is difficult to determine the specific location of the sample (how deep it is from the ground), and the sampling process is labor-intensive and dirty.

[0080] The soil quality detection component is used to insert into the soil sample taken out after the soil sampling component leaves the ground and detect the data value of the soil sample taken out by the soil sampling component. It is positioned on the vehicle plate 110 and is a prior art.

[0081] Furthermore, the soil detection component includes a sealing plate 310, a detection probe 320 and a shifting robotic arm 330; the sealing plate 310 is a hard circular plate, and its diameter is 0.8 to 0.95 times the inner diameter of the soil detection tube 230; the number of detection probes 320 is multiple, and the types are various, which are fixed on one end face of the sealing plate 310, and are used to detect various values ​​of the soil samples taken out; the shifting robotic arm 330 is a multi-degree-of-freedom robotic arm, which operates under the coordinated control of the power component and the control unit; the sealing plate 310 is fixed on the shifting robotic arm 330.

Both are existing technologies and will not be described in detail here.

[0087] Preferably, the control unit is a combination of a programmable logic controller and control buttons.

[0088] When using the field measurement equipment for power grid layout planning in the embodiment of the present application, the steps are as follows:

[0089] First, the rope pulling assembly 251 is controlled to shorten so that the cutting rope 250 is in a relaxed state;

[0090] Then, insert the cutting rope 250 close to the clamping block 242 into the clamping block 242 so that the cutting rope 250 close to the cutting ring 240 is placed in the side annular groove 241;

[0091] The soil probe tube 230 is controlled to rotate around itself and simultaneously to descend; after reaching the target depth, the rope pulling assembly 251 is controlled to extend, thereby causing the cutting rope 250, which is close to the clamping block 242, to break away from the clamping block 242 and become straight; then the soil probe tube 230 is controlled to continue rotating, so that the cutting rope 250 in the space enclosed by the cutting ring 240 acts as a rope cutter to cut and sever the soil sample;

[0092] The soil detection tube 230 is controlled to move upward to complete sampling. During the upward movement, the cutting rope 250 plays a certain role in holding the soil sample to prevent it from escaping from the soil detection tube 230 under the influence of its own weight.

[0112] Preferably, a cleaning nozzle 280 is also provided outside the soil detection tube 230, and the cleaning nozzle 280 can clean the detection probe 320. Example

[0113] like Figure 13 and Figure 14 As shown, in order to further improve the practicality of the present application, automatic measurement of different positions of the same soil sample is automatically achieved; the embodiment of the present application further optimizes and improves the structure of the soil detection tube 230 on the basis of the above embodiment, and provides a side groove 233 on the side wall of the soil detection tube 230, and adds an inner rotating tube 290 inside the soil detection tube 230.

[0120] When it is necessary to test different positions of the same sample, the soil detection tube 230 is controlled to rotate to a horizontal state, and then a test is performed, and then part of the soil sample is discharged as needed; at this time, the inner tube fixing component 234 is controlled to extend to fix the inner rotating tube 290; thereafter, the soil detection tube 230 is controlled to rotate forward and backward around its own axis, and the discharged part of the soil sample is cut off, and a second test is performed after cleaning the probe; and so on, multiple tests are performed on the same sample. Example

[0121] like Figure 15 As shown, in order to ensure the structural strength of the soil detection tube 230 while ensuring that the soil sample can be effectively cut off and to avoid the side grooves 233 seriously affecting the service life of the soil detection tube 230, the embodiment of the present application optimizes and improves the structure of the side grooves 233 and the structure of the inner tube fixing assembly 234 on the basis of the above embodiment; specifically:

[0122] The side groove 233 is an arc-shaped through groove, which is horizontally arranged when the soil exploration tube 230 is vertically placed, and has a cross-section in the shape of a bracket;

[0123] The inner tube fixing assembly 234 includes a sliding carrier 235 and a driving wheel 236;

[0124] The sliding carriage 235 is a bracket for driving the wheel 236, and is slidably positioned at the bottom of the sliding plate 220, and moves closer to or away from the soil exploration tube 230 under the coordinated control of the power assembly and the control unit;

[0125] The end face of the driving wheel 236 is parallel to the bottom surface of the sliding plate 220, and a protrusion is provided on the side wall that matches the pit on the inner rotating tube 290. It rotates around its own axis and is connected to the sliding carrier 235, and rotates under the coordinated control of the power component and the control unit. When it is necessary to cut off part of the discharged soil sample, the driving wheel 236 is controlled to move and close to the side wall of the inner rotating tube 290, and then drives the inner rotating tube 290 and the soil detection tube 230 to rotate differentially, thereby realizing the cutting of the soil sample.

[0126] Preferably, in order to facilitate the preservation of soil samples, a sample storage component is also positioned on the carrying trolley; the sample storage component includes a pillar 610, a top turntable 620 and a plurality of sample boxes 630; the pillar 610 plays a bearing role, is fixed on the vehicle plate 110, is arranged longitudinally, and is located on the other side of the soil sampling component; the top turntable 620 is a horizontal turntable that rotates under the control of the control unit; the sample box 630 has a plurality of compartments, and at least one sample box 630 is placed on the top turntable 620; when in use, the soil sample is tested in conjunction with the soil detection tube 230 with the inner rotating tube 290, and the soil sample slices are stored separately (that is, the soil detection tube 230 is controlled to rotate above the sample box 630 to slice the soil sample so that it naturally falls into the sample box 630).

[0127] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various modifications and variations are readily apparent to those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
