Description

Technical Field

[0001] This utility model relates to the field of engineering exploration technology, and in particular to a patch electrode fixing device for the side of a wall. Background Technology

[0002] Construction engineering survey refers to the activities of surveying, exploring and testing the topography, geology and hydrology to meet the needs of planning, design, construction, operation and comprehensive management of engineering construction, and providing corresponding results and data. Surveying, design, treatment and monitoring activities in geotechnical engineering also fall under the scope of engineering survey.

[0003] Engineering surveying is a comprehensive applied science that studies and investigates the geological and geographical characteristics of engineering construction sites and their relationship to engineering construction. It is essential for the planning, design, construction, operation, and comprehensive management of urban construction, industrial and civil buildings, railways, roads, coastal ports, power transmission and pipeline projects, water conservancy and hydraulic structures, mining and underground projects. Through mapping, exploration, testing, and comprehensive evaluation of topographic, geological, and hydrological elements, engineering surveying provides the basic data required for feasibility assessment and construction. It is the primary link in basic construction. Good engineering surveying, especially preliminary surveying, can provide detailed demonstration of the construction site, ensure the rational implementation of the project, and promote the achievement of the best economic, social, and environmental benefits.

[0004] In high-density resistivity exploration, stable contact between the electrode and the target medium surface is the core prerequisite for ensuring effective current injection and accurate data acquisition. In the application scenarios of traditional patch electrodes on hard surfaces (such as building walls, concrete structures, and rock masses), existing technologies have significant limitations.

[0005] In practical applications, when high-density electrochemical methods are used on concrete walls, the electrodes cannot be directly fixed to the wall surface. Instead, they need to be secured with tape and coupled with objects such as soil blocks to the hard wall surface. This method has low installation efficiency, insufficient coupling stability, and weak environmental tolerance. Utility Model Content

[0006] The purpose of this invention is to provide a patch electrode fixing device for the side of a wall, which solves the problems of low installation efficiency, insufficient coupling stability and weak environmental tolerance in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a patch-type electrode fixing device for the side of a wall, comprising a coupling patch, an adhesive device, and a base. The coupling patch includes a fixed end and a rotating shaft. The adhesive device includes a rotating groove and double-sided adhesive. The base has a fixed groove on one side of its top, which passes through and is rotatably connected to the rotating shaft. Both ends of the fixed end are fixedly connected to one end of the rotating shaft. An adhesive surface is fixedly connected to the top of the base. A patch groove is formed through the middle of the top of the base. A pre-set hole is formed through the middle of the bottom of the base. A rotating groove is formed on one side of the top of the adhesive device. Double-sided adhesive is fixedly connected to the bottom of the adhesive device, and the double-sided adhesive is bonded to the adhesive surface.

[0008] By adopting the above technical solution, it can be directly fixed to a hard wall, can be repeatedly disassembled and has strong adhesion, can reduce grounding resistance, and avoid the electrodes being unable to supply power effectively. Using this device can simplify the high-density electrical resistivity tomography survey work on hard walls, quickly and accurately complete the electrode layout, and improve the accuracy of the survey measurement.

[0009] As a further description of the above technical solution: the coupling patch is formed by curing a mixture of carbon nanotubes, graphene composite conductive paste (60% to 75%) and polyurethane matrix (25% to 40%), and has a certain degree of adhesion. The composite conductive paste is composed of carbon nanotubes and graphene in a mass ratio of 1:2 to 1:5. At the same time, the coupling patch has a certain thickness and can be attached between the electrode patch and the wall.

[0010] By adopting the above technical solution, the polyurethane matrix gives it a certain degree of adhesion, which can better adhere to the electrode patch and the wall, ensure good coupling between the electrode and the wall, reduce loss during signal transmission, improve the quality of the detection signal, and a certain thickness can provide stable support and adhesion foundation for the electrode patch.

[0011] As a further description of the above technical solution: the double-sided adhesive is made of polyurethane polymer material, which has strong adhesion, can be washed with water, and recovers its adhesiveness after drying.

[0012] By adopting the above technical solution, if the double-sided tape becomes contaminated with dust or other impurities that affect its adhesiveness during actual use, it can be easily cleaned to restore its adhesiveness, thus extending the service life of the double-sided tape and reducing the cost of use.

[0013] As a further description of the above technical solution: a polytetrafluoroethylene wear-resistant bushing is provided between the rotating shaft and the rotating groove.

[0014] By adopting the above technical solution, the flexibility and stability of the coupling patch angle adjustment are ensured, which is conducive to adjusting the bonding angle between the coupling patch, the electrode patch, and the wall according to actual needs.

[0015] As a further description of the above technical solution: the size of the adhesive surface is consistent with the size of the adhesive device.

[0016] By adopting the above technical solution, problems such as weak adhesion and local lifting are avoided, thereby ensuring the connection stability between the adhesive device and the base, and thus improving the stability and reliability of the entire patch electrode fixing device.

[0017] As a further description of the above technical solution: the patch groove is slightly larger than the electrode patch of the high-density electrochemical method, and the high-density electrochemical electrode patch can be fixed by the coupling patch. The inner wall of the patch groove is provided with a conductive silver paste coating.

[0018] By adopting the above technical solution, the conductivity between the electrode patch and the coupling patch can be further enhanced, the contact resistance can be reduced, and the signal transmission efficiency can be improved.

[0019] As a further description of the above technical solution: the preset hole can be passed through by the electrode wire and the metal clamp.

[0020] By adopting the above technical solution, the connection between the electrode wire and the electrode patch is facilitated, enabling the electrode signal to be transmitted smoothly to the detection equipment.

[0021] As a further description of the above technical solution: the base is made of acrylic material.

[0022] By adopting the above technical solutions, acrylic material has good transparency, chemical stability and weather resistance, beautiful appearance and resistance to certain chemical corrosion and environmental factors. At the same time, it also has a certain strength and rigidity, which can provide a stable support structure for the entire fixing device, ensuring the stability and reliability of the device during use.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] 1. The present invention provides a patch electrode fixing device for the side of a wall. Firstly, through the synergistic effect of carbon nanotubes, graphene composite conductive paste and polyurethane matrix, the coupling patch has both high conductivity and flexible bonding ability, which can adaptively fill the micro-cracks on the wall surface and significantly improve the coupling stability.

[0025] 2. This utility model provides a patch-type electrode fixing device for the side of a wall. It supports quick pasting with double-sided adhesive made of polyurethane polymer material and can be reused after rinsing with water. It reduces the cost compared to traditional tape. The maximum load-bearing capacity of a single device is 5kg, ensuring that the device is firmly fixed. The coupling agent and fixing device are integrated into one unit, which enables quick installation and can effectively improve the work efficiency of the installation personnel.

[0034] Example 1:

[0035] A high-density electrostatic fixing device comprises a coupling patch 3, an adhesive device 4, and a base 7. The coupling patch 3 is connected to the base 7 via a fixed end 1 at its end and a rotating shaft 2, and the adhesive device 4 is connected to the base 7 via an adhesive surface 9.

[0036] like Figure 2 As shown, the coupling patch 3 has a fixed end 1 and a rotating shaft 2 at its end. The coupling patch has both high conductivity and flexible bonding ability, and can be rotated to a suitable angle to adaptively fill micro-cracks on the wall surface.

[0037] like Figure 3 As shown, the adhesive device 4 is a double-sided adhesive made of polyurethane polymer material, which supports quick bonding and can be reused after rinsing with water. One side of the adhesive device acts on the wall, and the other side acts on the adhesive surface 9 located on the base 7. One side of the adhesive device 4 has a rotating groove 5, through which the coupling patch 3 can rotate.

[0038] Specifically, the size of the coupling patch 3 is slightly smaller than the inner square opening of the adhesive device 4, which facilitates the rotation of the coupling patch 3. The size of the adhesive device 4 is consistent with that of the adhesive surface 9. When connected, the fixed end 1, the rotating groove 5 and the fixed groove 8 are located on the same side.

[0039] like Figure 4 As shown, the base 7 is made of acrylic material, with a fixing groove 8 on one side, an adhesive surface 9 connected to the adhesive device 4, a patch groove 10 for fixing electrode patches, and a preset hole 11 through which wires and metal clips can pass.

[0040] Specifically, the inner wall of the patch groove 10 is coated with a conductive silver paste coating, which, together with the coupling patch 3, better prevents the electrode patch from shaking. When the device is connected, the vertical center lines of the coupling patch 3, the adhesive device 4, and the base coincide.

[0041] Example 2:

[0042] This utility model embodiment provides a method of using a fixing device capable of high-density electrical flux.

[0043] Specifically: after removing the release film from one side of the adhesive device 6, it is pasted onto the adhesive surface 9 of the base 7;

[0044] The electrode patch is embedded in the patch groove 10, and the wires and metal clips are led out through the preset hole 11 and connected to the electrode and the main cable interface of the surveying machine.

[0045] Adjust the rotating shaft 2 to make the coupling patch 3 fit between the electrode patch and the wall;

[0046] After removing the release film from the other side of the adhesive device 6, stick it to the wall;

[0047] Compared with existing technologies, this utility model has a simple structure, can easily fix electrode patches, effectively reduce grounding resistance, improve measurement accuracy, and simplify high-density electrical resistivity tomography (EDT) work.

[0048] Working principle: Start measurement, after the test is completed, remove the device from the wall, rotate the coupling device to a certain angle, pull out the patch electrode, and retrieve the fixing device. Specifically, when retrieving the fixing device, you can use clean water to remove surface dirt and place it in the sun to dry, maintain the life of the double-sided adhesive for the next use. It should be noted that if the device is stuck to the wall and cannot be removed, you can drip clean water through the gap to achieve non-destructive peeling.

[0049] 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.
