Description

Technical Field

[0001] This utility model relates to the field of electrical exploration equipment technology, and in particular to a multifunctional electrode array for electrical exploration. Background Technology

[0002] A multifunctional electrode array for electrical exploration is an important electrical exploration device. It consists of multiple electrodes and can be used for various electrical measurements, such as resistivity method, induced polarization method, and natural electric field method. It is usually used in conjunction with an electrical exploration instrument to provide geologists with rich subsurface information, help them better understand subsurface structures, and provide scientific basis for resource development, environmental protection, and engineering construction.

[0003] However, since each electrode is connected to the measuring cable via a branch line, and most existing multi-functional electrode arrays for electrical exploration on the market do not allow for quick connection of the branch line and measuring cable, they mostly use a special plug connected to the branch line to directly hold the measuring cable in place. This causes the branch line and measuring cable to easily break when the operator moves the measuring cable, thus affecting subsequent exploration operations.

[0004] Therefore, those skilled in the art have provided a multifunctional electrode array for electrical exploration to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multifunctional electrode array for electrical exploration. A reset spring in the fixing mechanism acts on a toggle block, keeping the movable plate in contact with the cover plate. This allows the cover plate to engage with the slot, securing the measuring cable within the fixed frame. The toggle block then rotates the movable plate, releasing the cover plate from the slot. A torsion spring, acting on the cover plate, causes it to open automatically, separating the measuring cable from the fixed frame.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A multifunctional electrode array for electrical exploration includes an electrode post, a measuring cable, and a fixing mechanism. A branch line is fixedly connected to the outer wall of the electrode post, and a connector is fixedly connected to the upper end of the branch line. A fixing mechanism is provided at the lower end of the measuring cable. The fixing mechanism includes a first shaft and a second shaft. A fixing frame is fixedly connected to the upper end of the connector. A cover plate is fixedly connected to the middle of the outer wall of the first shaft. Torsion springs are sleeved on both sides of the outer wall of the first shaft.

[0008] A movable plate is fixedly connected to the middle of the outer wall of the second shaft. A slot is provided at the upper end of the outer wall of the front end of the movable plate. A moving groove is provided in the middle of the rear end of the fixed frame. A return spring is fixedly connected to the inner wall of the front end of the moving groove. A toggle block is fixedly connected to the rear end of the return spring. Multiple contact surfaces are provided on the outer walls of both the front and rear ends of the measuring cable. A contact ring is fixedly connected to the center of the bottom surface inside the fixed frame.

[0009] Through the above technical solution, the reset spring inside the movable groove in the fixing mechanism acts on the actuating block, so that the movable plate fixedly connected to the actuating block remains in contact with the cover plate fixedly connected to the first shaft, so that the outer wall of the rear end of the cover plate is engaged with the slot on the movable plate, thus fixing the measuring cable in the fixed frame. By using the actuating block to drive the movable plate to rotate along the second shaft, the engagement state between the cover plate and the slot can be released. In conjunction with the two torsion springs sleeved on the first shaft acting on the cover plate, the cover plate opens by itself, allowing the measuring cable to separate from the fixed frame.

[0010] Furthermore, the upper end of the electrode post is fixedly connected to a strike block, and the lower end of the contact ring passes through the fixing frame and is fixedly connected to the connector.

[0011] With the above technical solution, the impact block fixedly connected to the upper end of the electrode post allows workers to easily drive the electrode into the ground by striking it with tools such as a hammer. The contact ring is fixedly connected to the connector, which connects the branch line to the connector and the contact ring.

[0012] Furthermore, both sides of the first shaft are rotatably connected to the fixed frame, and the outer wall of the rear end of the cover plate is snapped into the slot.

[0013] The above technical solution uses a slot on the outer wall of the cover plate to engage with the movable plate, preventing the cover plate from rotating along the first shaft on the fixed frame.

[0014] Furthermore, the side of the torsion spring furthest from the center of the first shaft is fixedly connected to the fixed frame, and the side of the torsion spring closest to the center of the first shaft is fixedly connected to the cover plate.

[0015] By using the above technical solution, the torsion spring is fixedly connected to the fixed frame and the cover plate. After the cover plate is released from the locking state of the slot, the torsion spring releases its elastic force, causing the cover plate to rotate and open on the fixed frame along the first shaft.

[0016] Furthermore, both sides of the second shaft are rotatably connected to the fixed frame, and the upper end of the actuating block passes through the moving slot and is fixedly connected to the movable plate;

[0017] By using the above technical solution, and by fixing the upper through-moving groove of the actuating block to the movable plate, the operator can use the actuating block to drive the movable plate to rotate along the second shaft on the fixed frame, thereby releasing the locking state between the cover plate and the slot.

[0018] Furthermore, the lower end of the actuating block extends through the moving groove to the outside of the fixed frame, and the inner wall of the contact ring is slidably connected to the contact surface;

[0019] The above technical solution allows the lower end of the toggle block to extend to the outside of the fixed frame, making it convenient for staff to press the toggle block to rotate the movable plate on the fixed frame and open the cover. Multiple contact surfaces are provided on the measuring cable to expose the internal wires, and the contact ring is slidably connected to the contact surface. This allows the measuring cable to connect with the branch line through the contact surface and the contact ring. At the same time, the sliding connection allows it to be easily removed from the fixed frame when the cover is open.

[0020] Furthermore, external connectors are fixedly connected to both sides of the measuring cable, and a pad is fixedly connected to the center of the lower end of the cover plate;

[0021] Through the above technical solution, the external connector fixedly connected to the measuring cable can be connected to external equipment such as an electrical prospecting instrument, and the pad fixedly connected at the center of the lower end of the cover plate can press the contact surface on the measuring cable and the contact ring tightly after the cover plate is closed, so as to prevent the measuring cable from loosening.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model proposes a multifunctional electrode array for electrical exploration. A reset spring inside the movable slot of the fixing mechanism acts on a toggle block, keeping the movable plate fixedly connected to the toggle block in contact with the cover plate fixedly connected to the first shaft. The outer wall of the rear end of the cover plate engages with a slot on the movable plate, fixing the measuring cable within the fixed frame. The toggle block drives the movable plate to rotate along the second shaft, releasing the cover plate from the slot. Two torsion springs on the first shaft act on the cover plate, causing it to open automatically, separating the measuring cable from the fixed frame. This achieves rapid connection between the branch line and the measuring cable while preventing easy disconnection between them. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figure 1-5 The present invention provides a specific embodiment of a multifunctional electrode array for electrical exploration, comprising an electrode post 1, a measuring cable 4, and a fixing mechanism 6. A branch line 3 is fixedly connected to the outer wall of the electrode post 1, and a connector 9 is fixedly connected to the upper end of the branch line 3. A fixing mechanism 6 is provided at the lower end of the measuring cable 4. The fixing mechanism 6 includes a first shaft 602 and a second shaft 605. A fixing frame 601 is fixedly connected to the upper end of the connector 9. A cover plate 603 is fixedly connected to the middle of the outer wall of the first shaft 602. Torsion springs 604 are sleeved on both sides of the outer wall of the first shaft 602.

[0033] A movable plate 606 is fixedly connected to the middle of the outer wall of the second shaft 605. A slot 607 is provided at the upper end of the outer wall of the front end of the movable plate 606. A moving groove 608 is provided in the middle of the rear end of the fixed frame 601. A return spring 609 is fixedly connected to the inner wall of the front end of the moving groove 608. A toggle block 610 is fixedly connected to the rear end of the return spring 609. Multiple contact surfaces 7 are provided on the outer walls of the front and rear ends of the measuring cable 4. A contact ring 8 is fixedly connected to the center of the bottom surface inside the fixed frame 601.

[0034] The reset spring 609 inside the movable slot 608 of the fixing mechanism 6 acts on the actuating block 610, so that the movable plate 606, which is fixedly connected to the actuating block 610, remains in contact with the cover plate 603, which is fixedly connected to the first shaft 602. This allows the outer wall of the rear end of the cover plate 603 to engage with the slot 607 on the movable plate 606, fixing the measuring cable 4 inside the fixing frame 601. The actuating block 610 drives the movable plate 606 to rotate along the second shaft 605, which releases the engagement between the cover plate 603 and the slot 607. In conjunction with the two torsion springs 604 sleeved on the first shaft 602 acting on the cover plate 603, the cover plate 603 opens by itself, allowing the measuring cable 4 to separate from the fixing frame 601. This achieves quick connection between the branch line 3 and the measuring cable 4 while avoiding the problem of easy disconnection between the branch line 3 and the measuring cable 4.

[0035] The upper end of the electrode post 1 is fixedly connected to the impact block 2, and the lower end of the contact ring 8 passes through the fixed frame 601 and is fixedly connected to the connector 9. The impact block 2 fixedly connected to the upper end of the electrode post 1 allows workers to easily drive the electrode into the ground by striking it with tools such as a hammer. The fixed connection between the contact ring 8 and the connector 9 allows the branch line 3 connected to the connector 9 to be connected to the contact ring 8. Both sides of the first shaft 602 are rotatably connected to the fixed frame 601. The outer wall of the rear end of the cover plate 603 is engaged with the slot 607. The engagement between the cover plate 603 and the slot 607 on the outer wall of the movable plate 606 prevents the cover plate 603 from moving along the first shaft 602. The fixed frame 601 rotates, and the side of the torsion spring 604 furthest from the center of the first shaft 602 is fixedly connected to the fixed frame 601, while the side of the torsion spring 604 closest to the center of the first shaft 602 is fixedly connected to the cover plate 603. By fixing the torsion spring 604 to the fixed frame 601 and the cover plate 603, after the cover plate 603 is released from the latching state of the slot 607, the torsion spring 604 releases its elastic force, causing the cover plate 603 to rotate and open on the fixed frame 601 along the first shaft 602. Both sides of the second shaft 605 are rotatably connected to the fixed frame 601. The upper end of the actuating block 610 passes through the moving slot 608 and is fixedly connected to the movable plate 606. By allowing the actuating block... The upper through-moving groove 608 and the movable plate 606 of 610 are fixedly connected, allowing the operator to use the actuating block 610 to rotate the movable plate 606 along the second shaft 605 on the fixed frame 601, releasing the cover plate 603 from the locking state of the slot 607. The lower end of the actuating block 610 passes through the moving groove 608 to the outside of the fixed frame 601, and the inner wall of the contact ring 8 is slidably connected to the contact surface 7. By allowing the lower end of the actuating block 610 to pass through the outside of the fixed frame 601, the operator can easily press the actuating block 610 to rotate the movable plate 606 on the fixed frame 601, opening the cover plate 603. Multiple contact surfaces 7 are provided on the measuring cable 4 to expose the internal wires. The contact ring 8 is slidably connected to the contact surface 7, allowing the measuring cable 4 to connect with the branch line 3 via the contact surface 7 and the contact ring 8. This sliding connection also allows the cable to be easily removed from the fixed frame 601 when the cover plate 603 is open. External connectors 5 are fixedly connected to both sides of the measuring cable 4, and a pad 10 is fixedly connected to the center of the lower end of the cover plate 603. The external connectors 5 fixedly connected to the measuring cable 4 allow connection to external equipment such as an electrical resistivity detector. The pad 10 fixedly connected to the center of the lower end of the cover plate 603, when the cover plate 603 is closed, compresses the contact surface 7 and the contact ring 8 on the measuring cable 4 to ensure a tight fit, preventing the measuring cable 4 from becoming loose.

[0036] Working principle: When using this multi-functional electrode array for electrical exploration, the operator first connects the external connector 5 on the measuring cable 4 to the electrical exploration instrument carried by the operator. Then, the operator marks the electrode installation points. After arriving at the installation points, the operator uses a hammer or other tools to strike the impact block 2 on the electrode post 1 to fix the electrode post 1 to the ground. Next, the operator places the measuring cable 4 into the fixing frame 601, ensuring that the contact surface 7 on the measuring cable 4 contacts the contact ring 8. Then, the cover plate 603 is closed, and the return spring 609 acts on the actuating block 610 to engage the cover plate 603 with the slot 607, thus securing the measuring cable 4. Fixed within the fixed frame 601, the branch line 3 is connected to the measuring cable 4 via the contact ring 8. The operator installs the required number of electrode posts 1 according to the measurement requirements and connects them to the measuring cable 4 via the branch line 3. Then, the operator uses an electrical prospecting instrument to conduct exploration. Finally, after the exploration is completed, the operator uses the toggle block 610 to drive the movable plate 606 to rotate along the second shaft 605, releasing the locking state between the cover plate 603 and the slot 607. In conjunction with the two torsion springs 604 sleeved on the first shaft 602, the cover plate 603 is opened by itself, allowing the measuring cable 4 to separate from the fixed frame 601, and the measuring cable 4 and electrode posts 1 are retracted.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
