Description

Technical Field

[0001] The present application relates to the technical field of soil sampling devices, and in particular to an automated sampling device for tunnel surveying. Background Art

[0002] With the development of artificial intelligence technology combined with rail transit technology, the technological level of inspection tools used by rail transit workers during construction has also been increasingly valued and developed, especially for the rail transit industry. Therefore, soil sampling auxiliary tools for tunnel surveys have become a hot spot in the development of rail transit application equipment. However, existing sampling devices mostly use shovels to excavate and sample, and it is inconvenient to store and transport samples after sampling, wasting time and human resources. Summary of the invention

[0003] In view of the shortcomings of the prior art and in order to improve the efficiency of soil sampling, the present application provides an automated sampling device for tunnel surveying.

[0004] The above invention objectives of the present application are achieved through the following technical solutions:

[0005] An automatic sampling device for tunnel surveying includes a mounting plate and a storage bag that can be opened and closed automatically. The top of the mounting plate is symmetrically provided with a plurality of screw holes and a power supply interface. The storage bag is fixedly connected to the bottom of the mounting plate. A metal shovel is fixedly connected to the opening of the storage bag. A camera is arranged above the opening of the storage bag. The camera is fixed to the side wall of the mounting plate and is electrically connected to a radar rangefinder.

[0006] In a preferred example, the present application can be further configured as follows: a plurality of partition bars are fixedly provided inside the storage bag, and the plurality of partition bars divide the storage bag into a plurality of sub-bags.

[0007] In a preferred example, the present application can be further configured as follows: electromagnet sheets are fixedly provided at both end openings of a plurality of the sub-bags, and when the sub-bags are closed, the electromagnet sheets are attracted to each other.

[0008] In a preferred example, the present application can be further configured as follows: the power supply interface is hexagonal in shape, and six metal needles are disposed inside the power supply interface.

[0009] In a preferred example, the present application may be further configured as follows: an object recognition sensor is disposed inside the storage bag, and the object recognition sensor is used to recognize the composition of the sample.

[0010] In summary, this application has the following beneficial technical effects:

[0011] 1. The metal shovel at the opening of the storage bag is used as an auxiliary excavation tool. It is relatively sharp and can easily dig the soil, rocks, etc. required for sampling. The storage bag that can be opened and closed automatically can store the excavated samples. The camera is electrically connected to the radar rangefinder, which allows construction workers to view the specific distance and position information of the equipment, so that it is convenient for workers to remotely operate the metal shovel for excavation and the opening and closing of the storage bag. The object recognition sensor can roughly identify the composition of the samples in the storage bag;

[0012] 2. The closing of each sub-bag is controlled by the magnetic induction of the electromagnet sheet. When the device is powered on, the electromagnet sheet at the opening of each sub-bag is connected to the power circuit, and each circuit is connected to the remote automatic control switch. When the worker remotely controls the switch of a sub-bag to close, the electromagnet of the storage bag is energized, and the electromotive force generated in the magnet forms electromagnetic induction, so that the upper and lower electromagnet sheets that were originally adsorbed together repel each other, and the sub-bag can be opened. In different construction environments, the storage bag can be opened and closed by remotely controlling the sampling to classify and store the samples, so that the soil samples of construction scenes in several different locations can be classified and brought back for testing and research;

[0013] 3. The special hexagonal power supply interface contains 6 metal pins. Compared with ordinary device power supply interfaces, the hexagonal shape makes the contact area larger and the connection between devices more secure. The 6 metal pins can increase the contact area with other connected devices and make the power supply current between devices more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1-3 As shown, an automatic sampling device for tunnel surveying includes a mounting plate 1 and a storage bag 2 that can be opened and closed automatically, a plurality of screw holes 3 and a power supply interface 4 are symmetrically arranged on the top of the mounting plate 1, the storage bag 2 is fixedly connected to the bottom of the mounting plate 1, a metal shovel 5 is fixedly connected to the opening of the storage bag 2, a camera 6 is arranged above the opening of the storage bag 2, the camera 6 is fixed to the side wall of the mounting plate 1, and the camera 6 is electrically connected to a radar rangefinder (not shown in the figure).

[0020] In this embodiment, the metal shovel 5 at the opening of the storage bag 2 is used as an auxiliary excavation tool. It is relatively sharp and can easily dig the soil, rocks, etc. required for sampling. The storage bag 2 that can be opened and closed automatically can store the excavated samples. The camera 6 is electrically connected to the radar rangefinder. First, the camera 6 is used to observe the object or environment to decide whether it needs to be stored. If it is to be stored, the radar rangefinder starts to emit electromagnetic waves to report the sampling position, so that the construction workers can view the specific distance position information of the equipment, thereby facilitating the workers to remotely operate the metal shovel 5 for excavation and the opening and closing of the storage bag 2.

[0021] In one embodiment, a plurality of partition bars 7 are fixedly disposed inside the storage bag 2 , and the plurality of partition bars 7 divide the storage bag 2 into a plurality of sub-bags 8 .

[0022] In this embodiment, three partition bars 7 divide the storage bag 2 into four sub-bags 8. The opening and closing of each sub-bag 8 is remotely controlled in different construction environments to classify and store the samples, thereby classifying the soil samples from construction scenes at four different locations and bringing them back for testing and research.

[0023] In one embodiment, electromagnet sheets 9 are fixedly provided at both end openings of a plurality of the sub-bags 8 , and when the sub-bags 8 are closed, the electromagnet sheets 9 are attracted to each other.

[0024] In this embodiment, the closing of the four sub-bags 8 is controlled by the magnetic induction of the electromagnet sheets 9. When the device is powered on, the electromagnet sheets 9 at the openings of the four sub-bags 8 are respectively connected to four power lines, each of which is connected to a remote automatic control switch. When a worker remotely controls the switch of a sub-bag 8 to close, the electromagnet of the storage bag 2 is energized, and an electromotive force is generated in the magnet to form electromagnetic induction, so that the upper and lower electromagnet sheets 9 that were originally adsorbed together repel each other, and the sub-bag 8 can be opened.

[0025] In one embodiment, the power supply interface 4 is hexagonal in shape, and six metal pins 10 are disposed inside the power supply interface 4 .

[0026] In this embodiment, the special hexagonal power supply interface 4 contains 6 metal needles 10. Compared with the ordinary device power supply interface 4, the hexagonal shape makes the contact area larger and the connection between devices more secure. The 6 metal needles 10 can increase the contact area with other connected devices and make the power supply current between devices more stable.

[0027] In one embodiment, an object recognition sensor (not shown in the figure) is disposed inside the storage bag 2, and the object recognition sensor is used to recognize the components of the sample.

[0028] In this embodiment, the object recognition sensor can roughly identify the components of the sample in the storage bag 2 .

[0029] The specific working principle of the automatic sampling device for tunnel survey of the present invention is as follows: first, the camera 6 is used to observe the object or environment to determine whether it needs to be collected. If it is to be collected, the radar rangefinder starts to emit electromagnetic waves to report the sampling position. One side of the metal shovel 5 is sharper and can easily dig the soil, rock, etc. required for sampling. The other side is equipped with a hinge of an electric controller (not shown in the figure), which can be electrically controlled to rotate the hinge to collect the excavated samples. Three partitions 7 divide the storage bag 2 into four sub-bags 8. The opening of each sub-bag 8 can be controlled remotely in different construction environments. The samples are classified and stored, so that the soil samples of construction scenes in four different locations are classified and brought back for detection and research. The closing of the four sub-bags 8 is controlled by the magnetic induction of the electromagnet sheet 9. When the device is powered on, the electromagnet sheets 9 at the openings of the four sub-bags 8 are respectively connected to four power lines, each of which is connected to a remote automatic control switch. When the worker remotely controls the switch of a sub-bag 8 to close, the electromagnet of the storage bag 2 is energized, and an electromotive force is generated in the magnet to form electromagnetic induction, so that the upper and lower electromagnet sheets 9 that were originally adsorbed together repel each other, and the sub-bag 8 can be opened.

[0030] The present invention and its embodiments are described above, which is not restrictive. What is shown in the accompanying drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and do not deviate from the purpose of the invention, they can creatively design structural methods and embodiments similar to the technical scheme, which should all fall within the scope of protection of the present invention.
