Description

Technical Field

[0001] This utility model relates to the field of electrode device technology, and in particular to an electrode device for exploration. Background Technology

[0002] In areas with excessively high grounding resistance, electrical exploration often encounters power supply interruptions, which affect testing efficiency. Years of practical experience have shown that increasing the depth of the electrodes into the soil and pouring high-concentration salt water at the electrode placement location can effectively reduce grounding resistance.

[0003] Therefore, the existing electrode for electrical exploration in areas with high grounding resistance, publication number CN222052100U, is used as follows: First, confirm that the external thread near the top of the electrode rod's outer wall is in a tight connection with the internal thread on the inner wall of the electrode groove's top. Second, use a hammer to drive the electrode into the preset depth of the electrode placement point. At this time, the electrode protrusion reduces the frictional contact area between the outer wall of the electrode cylinder and the soil. Third, rotate the electrode handle to disengage the external thread near the top of the electrode rod from the internal thread on the inner wall of the electrode groove's top, and remove the electrode rod from the electrode groove. At this time, the cross-shaped bottom end of the electrode rod can locally disturb the soil at the bottom of the electrode. Fourth, pour an appropriate amount of high-concentration brine into the electrode groove. Then, reinstall the electrode rod into the electrode groove, ensuring a tight connection between the external thread near the top of the electrode rod's outer wall and the internal thread on the inner wall of the electrode groove's top. Finally, screw the cross-shaped bottom end of the electrode rod into the disturbed soil, ensuring full coupling between the bottom of the electrode rod and the soil.

[0004] However, when using this motor device, in order to add high-concentration saline, the electrode rod needs to be pulled out of the electrode cylinder. The frequent insertion and removal operations increase the risk of accidental damage to the electrode rod (mechanical damage, contamination), reduce the service life of the electrode rod, and the insertion and removal operations are relatively troublesome. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing an electrode device for exploration.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an electrode device for exploration, comprising an electrode cylinder and an electrode rod, wherein an electrode drill bit is fixedly connected to the bottom of the electrode rod and is disposed below the electrode cylinder; the electrode rod and the electrode drill bit are hollow; a brine delivery pipe is disposed inside the electrode rod and the electrode drill bit; a movable block is fixedly connected to the bottom of the brine delivery pipe; the movable block is inserted into the hollow part at the bottom of the electrode drill bit; an annular flow groove is formed on the inner side of the electrode drill bit and above the movable block; and liquid outlets are formed on both sides of the bottom of the brine delivery pipe.

[0007] Preferably, a sealing gasket is provided on the inner side of the electrode drill bit, directly opposite the liquid outlet.

[0008] Preferably, the brine delivery pipe is threadedly connected to the electrode rod.

[0009] Preferably, it also includes an electrode handle, which is threaded to the top of the electrode rod, and the brine delivery pipe passes through the electrode handle.

[0010] Preferably, the electrode handle has a movable groove at the top, and the brine delivery pipe has a rotating handle fixedly connected to the top.

[0011] Preferably, the turning handle is disposed inside the movable groove.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, when brine is input, the brine flows in the brine delivery pipe and flows out from the outlet. It can then flow downward through the gap between the annular flow groove and the movable block and the inner side of the electrode rod, and then penetrate into the soil at the bottom of the electrode rod. This allows brine to be added without removing the electrode rod, solving the problem of frequent insertion and removal and easy damage in traditional devices.

[0014] 2. In this utility model, by setting the electrode handle and the top of the electrode rod to be threadedly connected, a gripping and hammering point is provided for the device, making it easy to insert the electrode into the soil. At the same time, the brine delivery pipe passes through the top of the device, forming an inlet for brine injection. The movable groove at the top of the electrode handle cooperates with the turning handle, allowing the operator to directly rotate the turning handle to control the movement of the brine delivery pipe and achieve precise control of brine delivery. The threaded connection between the brine delivery pipe and the electrode rod allows for flexible adjustment of the depth of the brine delivery pipe while ensuring connection stability. The sealing gasket on the inside of the electrode drill bit enhances the sealing of the outlet, preventing brine leakage and the intrusion of external impurities, and extending the service life of the device.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figure 1-5 As shown, an electrode device for exploration includes an electrode cylinder 1 and an electrode rod 2. An electrode drill bit 3 is fixedly connected to the bottom of the electrode rod 2 and is located below the electrode cylinder 1. The electrode rod 2 and the electrode drill bit 3 are hollow. A brine delivery pipe 7 is provided inside the electrode rod 2 and the electrode drill bit 3. A movable block 6 is fixedly connected to the bottom of the brine delivery pipe 7 and is inserted into the hollow part of the bottom of the electrode drill bit 3. An annular flow groove 9 is opened on the inner side of the electrode drill bit 3 and above the movable block 6. Liquid outlets 10 are opened on both sides of the bottom of the brine delivery pipe 7.

[0024] In this technical solution, a hollow electrode rod 2 and electrode drill bit 3 are set to form an internal channel for brine delivery, allowing brine to be delivered from the top of the electrode to the bottom soil. The electrode drill bit 3 is used to break the soil, reducing the tightness between the soil and the electrode cylinder 1, making it easier for workers to pull out the electrode device. A brine delivery pipe 7 is set, which passes through the electrode handle 4 and the electrode rod 2 and extends into the electrode drill bit 3, serving as the main path for brine delivery. The outlets 10 on both sides of its bottom can discharge brine. A movable block 6 is set and fixed to the bottom of the brine delivery pipe 7, which is inserted into the hollow part at the bottom of the electrode drill bit 3. By controlling the upward or downward movement of the brine delivery pipe 7, the movable block 6 can be moved accordingly, thereby opening or closing the brine delivery channel.

[0025] By setting up an annular flow channel 9, the brine delivery pipe 7 is controlled to move upward, causing the outlet 10 to slide upward to the same height as the annular flow channel 9. The movable block 6 is driven to slide upward and follows the outlet 10 into the interior of the annular flow channel 9. At this time, the outer side of the brine delivery pipe 7 and the movable block 6 are in clearance fit with the inner side of the electrode rod 2. When the brine flows out from the outlet 10, it can flow downward through the gap between the annular flow channel 9 and the movable block 6 and the inner side of the electrode rod 2, and then penetrate into the soil at the bottom of the electrode rod 2.

[0026] like Figure 5 As shown, a sealing gasket 11 is provided on the inner side of the electrode drill bit 3, directly opposite the liquid outlet 10.

[0027] In this technical solution, the sealing performance between the brine delivery pipe 7 and the electrode drill bit 3 is enhanced to prevent external soil particles or moisture from entering the device, avoid contamination or corrosion of components such as the electrode rod 2 and the brine delivery pipe 7, and extend the service life of the device.

[0028] like Figure 4 As shown, the brine delivery pipe 7 is threadedly connected to the electrode rod 2.

[0029] In this technical solution, the position of the movable block 6 and the electrode drill bit 3 can be fixed by the threaded connection. When the electrode cylinder 1 and the electrode rod 2 are drilled into the ground, the movable block 6 can prevent soil from entering the interior of the electrode drill bit 3. Furthermore, by rotating, the depth of the brine delivery pipe 7 inside the electrode rod 2 can be flexibly adjusted to meet the different height requirements of the brine delivery pipe 7 when delivering brine.

[0030] like Figure 4 As shown, it also includes an electrode handle 4, which is threaded to the top of the electrode rod 2, and the brine delivery pipe 7 is installed through the electrode handle 4.

[0031] In this technical solution, by setting an electrode handle 4, it is convenient for workers to embed the electrode device into the ground by striking the electrode handle 4 with a hammer.

[0032] like Figure 4 As shown, the electrode handle 4 has a movable groove 5 at the top, and the brine delivery pipe 7 is fixedly connected to a screw handle 8 at the top, which is located inside the movable groove 5.

[0033] In this technical solution, by setting up a movable groove 5 and a turning handle 8, the movable groove 5 is opened at the top of the electrode handle 4, providing space for the turning handle 8 to rotate; the operator can insert a tool or finger into the movable groove 5 to directly rotate the turning handle 8, thereby driving the brine delivery tube 7 to rotate.

[0034] Working principle: First, the electrode handle 4 is struck with a hammer, and the electrode cylinder 1 and electrode rod 2 are embedded into the ground through the electrode drill bit 3. At this time, the brine delivery pipe 7 is threadedly connected to the electrode rod 2, and the movable block 6 is fixed at the bottom of the brine delivery pipe 7, which can prevent soil from entering the electrode drill bit 3. When brine needs to be injected, the operator rotates the handle 8 in the movable groove 5 at the top of the electrode handle 4, which drives the brine delivery pipe 7 to rotate and move upward, so that the movable block 6 slides upward. The outlet 10 slides upward to the same height as the annular flow groove 9. At this time, the outer side of the brine delivery pipe 7 and the movable block 6 are in clearance fit with the inner side of the electrode rod 2. The brine is injected from the top of the brine delivery pipe 7, flows out through the outlet 10, and flows downward through the annular flow groove 9 and the gap between the movable block 6 and the inner side of the electrode rod 2, penetrating into the soil at the bottom of the electrode rod 2, thus completing the brine addition.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
