Technical Field

[0001] This utility model relates to the field of geophysical exploration instrument technology, and in particular to a towed transient electromagnetic instrument device. Background Technology

[0002] The towed transient electromagnetic instrument is a geophysical instrument used for geological exploration based on the transient electromagnetic method. It is used to detect and image underground conductors. It mainly consists of a towed transmitting coil, a receiving coil, and the transient electromagnetic instrument body. By controlling the movement of the transmitting and receiving coils on or near the ground surface, it can achieve rapid detection over a large area. This method is particularly suitable for fields such as geological surveys, mineral exploration, and groundwater detection.

[0003] Since transient electromagnetic instruments are generally used for long-term outdoor detection, strong sunlight directly shining on the display screen during the day can interfere with the image on the screen, making it difficult for the human eye to see the content on the screen, thus affecting the normal outdoor use of the transient electromagnetic instrument.

[0004] Therefore, how to provide a towed transient electromagnetic instrument is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a towable transient electromagnetic instrument device, which solves the problem that the display screen of existing transient electromagnetic instruments is interfered with by strong sunlight when used outdoors, thus affecting the outdoor use of the transient electromagnetic instrument.

[0007] The sunshade assembly also includes a movable groove, a movable block, and a support rod assembly. The movable groove is opened on the side of the fixed base, the movable block is movably connected inside the movable groove, and the support rod assembly is set on the movable block.

[0008] The support rod assembly includes a first side rod, a middle rod, and a second side rod. The middle rod is located between the first side rod and the second side rod. The number of movable blocks is the same as the sum of the number of the first side rod, the middle rod, and the second side rod. One end of the first side rod, the middle rod, and the second side rod is fixed to the movable block, and the sunshade film is set on the end of the first side rod, the middle rod, and the second side rod away from the movable block.

[0009] One side of the first side rod is fixed to the surface of the electromagnetic instrument body.

[0010] The end of the second side rod away from the movable block has an extension component for the display screen.

[0011] The extension assembly includes a mounting base and an extension rod. The mounting base is fixed to the second side rod, the extension rod is rotatably connected to the mounting base, and the shading film is fixed to the surface of the extension rod.

[0012] The sunshade assembly also includes a positioning groove and a rubber protrusion. The positioning groove is opened inside the movable groove, and the rubber protrusion is fixed on the surface of the movable block at the position corresponding to the positioning groove. The rubber protrusion is movably engaged with the positioning groove.

[0013] The extension assembly also includes a position locking assembly, which includes a damping rubber ring, an elastic block, and a locking groove. The damping rubber ring is fixed on the side of the extension rod near the mounting base, and the other end of the damping rubber ring is tightly fitted to the side of the mounting base. The elastic block is fixed on the extension rod near the mounting base, and the locking groove is opened on the side of the mounting base at the position of the elastic block. The elastic block is movably locked inside the locking groove.

[0014] The beneficial effects of this utility model are:

[0015] By setting up a sunshade component, pulling the sunshade component when needed will cause it to rotate around the axis of the fixed base, allowing it to extend in a "fan shape" and block half of the display screen. Under the oblique sunlight, the strong light will be blocked by the sunshade film on the sunshade component, thus preventing the sunlight from directly shining on the display screen and affecting the viewing experience. This solves the problem that the display screen of the existing transient electromagnetic instrument is interfered with by strong sunlight when used outdoors, which affects the outdoor use of the transient electromagnetic instrument.

[0016] By setting up an extension component, which rotates on the sunshade to control the movement of the sunshade film, the extension component further shades the display screen below, thus providing further shading for the display screen when the sunlight is stronger. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] Example 1

[0025] refer to Figure 1-4 In this embodiment, the device includes an electromagnetic instrument body 1 and a display screen 2, with the display screen 2 embedded in the side of the electromagnetic instrument body 1. A mounting base 3 is provided on the surface of the electromagnetic instrument body 1 at the location of the display screen 2. The mounting base 3 has a semi-circular design and a sunshade assembly 4 is provided on the mounting base 3. The sunshade assembly 4 includes a sunshade film 5, which covers the display screen 2. The sunshade assembly 4 also includes a movable groove 6, a movable block 7, and a support rod assembly 8. The movable groove 6 is located on the side of the mounting base 3 and has an arc-shaped design, with the center of the arc 6 coinciding with the axis of the mounting base 3. The movable block 7 is movably connected to the movable groove 6. Inside the groove 6, the support rod assembly 8 is set on the movable block 7. The sunshade assembly 4 also includes a positioning groove 15 and a rubber protrusion 16. The positioning groove 15 is a hemispherical groove, and the shape of the rubber protrusion 16 matches the shape of the positioning groove 15. It should be noted that the number of positioning grooves 15 is greater than the number of rubber protrusions 16, and the number of rubber protrusions 16 matches the number of movable blocks 7. The positioning grooves 15 are arranged at equal intervals in the movable groove 6. The positioning grooves 15 are opened inside the movable groove 6. The rubber protrusions 16 are fixed on the surface of the movable block 7 at the position corresponding to the positioning groove 15. The rubber protrusions 16 are movably engaged with the positioning grooves 15.

[0026] The support rod assembly 8 includes a first side rod 9, a middle rod 10, and a second side rod 11. The middle rod 10 is located between the first side rod 9 and the second side rod 11. The number of movable blocks 7 is the same as the sum of the first side rod 9, the middle rod 10, and the second side rod 11. The number of middle rods 10 is greater than one. One end of the first side rod 9, the middle rod 10, and the second side rod 11 is fixed to the movable block 7. The width of the movable block 7 matches the width of the movable groove 6, so that the movable block 7 moves along the interior of the movable groove 6. The range of motion of the movable block 7 is the range of the movable groove 6. The sunshade film 5 is set on the end of the first side rod 9, the middle rod 10, and the second side rod 11 away from the movable block 7. One side of the first side rod 9 is fixed to the surface of the electromagnetic instrument body 1. During operation, it is necessary to first pull the first side rod 9. The second side rod 11 moves away from the first side rod 9 by moving within the movable slot 6 via the movable block 7. This pulls the sunshade film 5, which in turn pulls the middle rod 10, causing the folded sunshade film 5 and the middle rod 10 to unfold. This creates a "fan shape" between the second side rod 11, the middle rod 10, the first side rod 9, and the sunshade film 5, thus partially blocking the display screen 2. When sunlight shines obliquely on the display screen 2, it is blocked by the unfolded sunshade film 5, preventing direct sunlight from affecting the viewing and operation of the display screen 2. It should be noted that when the sunshade component 4 is retracted, it is offset from the display screen 2, so it does not easily affect the operation of the display screen 2.

[0027] Example 2

[0028] refer to Figure 1-4In this embodiment, the end of the second side rod 11 away from the movable block 7 is rotatably equipped with an extension assembly 12 for the display screen 2. The extension assembly 12 includes a mounting base 13 and an extension rod 14. The mounting base 13 is fixed to the second side rod 11, and the extension rod 14 is rotatably connected to the mounting base 13. The sunshade film 5 is fixed to the surface of the extension rod 14. The extension assembly 12 also includes a position locking assembly 17, which includes a damping rubber ring 18, an elastic block 19, and a locking groove 20. The damping rubber ring 18 is fixed to the side of the extension rod 14 near the mounting base 13, increasing the friction between the damping rubber ring 18 and the mounting base 13. The position of the extension rod 14 is positioned by increasing the friction between the extension rod 14 and the mounting base 13. The other end of the damping rubber ring 18 is tightly attached to the side of the mounting base 13. To further lock the position, the elastic block 19 is fixed to the extension rod 14 near the mounting base 13. The locking groove 20 is formed in the mounting base 14. The side of the base 13 is located at the position of the elastic block 19. The elastic block 19 is movably locked inside the locking groove 20. It should be noted that the elastic block 19 is also made of rubber, and the locking groove 20 and the elastic block 19 are on the same plane. Moreover, there is more than one locking groove 20, while there is only one elastic block 19. When the extension rod 14 rotates, it will drive the elastic block 19 to rotate. When the extension rod 14 rotates to the appropriate position, the elastic block 19 is locked in the corresponding locking groove 20 to stabilize the extension rod 14. During operation, when the sunshade component 4 cannot meet the requirements, first rotate the extension rod 14 to make it rotate on the mounting base 13. The rotation angle of the extension rod 14 can be adjusted according to actual use. When rotated to the appropriate position, the extension rod 14 will be located directly above the display screen 2 to increase the sunshade area of ​​the display screen 2, thereby further improving the sunshade effect. It should be noted that when the extension rod 14 is retracted, it needs to be rotated away from the display screen 2 so that it does not block the display screen 2.
