[0031] In order to further explain the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific implementation, structure, features and effects according to the utility model are described in detail as follows in combination with the drawings and preferred embodiments.
[0032] Please refer to Figures 1-9The embodiment aims to provide a cathode protection potential acquisition instrument, which comprises an acquisition instrument arranged in a test pile, and at least comprises a shell 1, a data cable plug 2 is arranged on the top of the shell 1, a waterproof part is arranged on the insertion end of the data cable plug 2, a fixing block 5 is arranged on the dustproof part, a cross slot 51 is arranged at the top center of the fixing block 5, and first heat dissipation fins 4 are arranged on the opposite sides of the shell 1.
[0033] A column groove 52 is arranged at the bottom of the fixing block 5, a screw block 53 is screw-mounted in the column groove 52, a through hole 531 is arranged at the center of the screw block 53, the diameter of the through hole 531 is larger than that of the insertion end of the data cable plug 2, and the insertion end of the data cable plug 2 penetrates the through hole 531.
[0034] The top of the fixing block 5 is made of rubber material, which has good elasticity and sealing performance. When the data cable plug 2 is inserted, the rubber slot 51 can be elastically deformed, and the slot 51 penetrates the top of the fixing block 5. The slot 51 is a cross-shaped channel that penetrates the top of the fixing block 5, allowing the insertion end of the data cable plug 2 to be inserted downward from the center. During the insertion process, the rubber slot 51 will bend downward to provide enough space for the plug.
[0035] When the insertion end of the data cable plug 2 is completely inserted into the slot 51, the slot 51 will partially recover due to the elasticity of the rubber, preliminarily fixing the plug. Next, rotate the screw block 53 to move it upward along the threads of the column groove 52. The top of the screw block 53 will gradually contact and lift the bottom of the slot 51, further compressing the rubber slot 51 to tightly fit it with the side wall of the data cable plug 2. When the screw block 53 is tightened, the tight fit between the rubber slot 51 and the plug side wall forms an effective dustproof and waterproof barrier, preventing dust and moisture from entering, and ensuring stable connection between the plug and the jack 14, avoiding signal transmission problems caused by looseness.
[0036] The inner walls of the opposite sides of the shell 1 are fixedly provided with insertion grooves 11, two square grooves 111 are arranged on the insertion grooves 11, third heat dissipation fins 15 are fixedly arranged on one side of the square grooves 111, one end of the first heat dissipation fins 4 penetrates the shell 1 and is arranged in the square grooves 111, and the first heat dissipation fins 4 are tightly fitted with the third heat dissipation fins 15, which not only ensures effective heat transfer, but also optimizes the heat dissipation effect by increasing the heat dissipation area.
[0037] The rubber pad 112 is fixedly arranged at the upper and lower ends of the square groove 111, is arc-shaped, and is inwardly inclined on one side. The rubber pad 112 not only has elasticity and wear resistance, but also can tightly clamp the first heat dissipation fin 4 to prevent loosening or falling off due to vibration or external force. The arc-shaped design and the inwardly inclined side of the rubber pad 112 can better adapt to the shape of the first heat dissipation fin 4 and provide more uniform clamping force, thereby not only enhancing the fit of the first heat dissipation fin 4, but also reducing noise and wear caused by direct contact between metals, thereby not only improving the stability of the first heat dissipation fin 4, but also prolonging the service life of the sampling instrument.
[0038] The other end of the first heat dissipation fin 4 penetrates the side wall of the test pile and extends to the external environment, so that the absorbed heat is quickly taken away by natural convection or forced air cooling, thereby ensuring the stable operation of the sampling instrument in a high-temperature environment. In addition to the heat dissipation effect, the first heat dissipation fin 4 also provides additional fixing support for the sampling instrument through the part penetrating the side wall of the test pile, thereby not only enhancing the stability of the sampling instrument in the test pile, but also improving the anti-seismic and anti-impact capabilities.
[0039] The shell 1 is provided with a jack 14 at the top, the insertion end of the data cable plug 2 is inserted into the jack 14, and the lower surface of the fixing block 5 is tightly attached to the top of the jack 14. This tight attachment not only prevents dust and moisture from entering, but also improves the durability and service life of the jack 14. By tightly attaching the lower surface of the fixing block 5 to the top of the jack 14, the insertion end of the data cable plug 2 is fixed and protected, thereby not only ensuring stable connection between the plug and the jack 14, but also preventing the plug from accidentally falling off or being damaged due to external force.
[0040] The other two side walls of the shell 1 are fixedly provided with limiting blocks 3, which are inverted U-shaped and have an opening downward groove. The limiting blocks 3 are used for clamping in the test pile. When the shell 1 is installed in the test pile, the groove of the limiting block 3 matches the protrusion or groove structure in the test pile, thereby achieving stable clamping.
[0041] Although the main function of the limiting block 3 is to fix the position of the shell 1 in the test pile, it also cooperates with the first heat dissipation fin 4. When the first heat dissipation fin 4 is inserted into the shell 1 through the insertion slot 11 and penetrates the side wall of the test pile, the presence of the limiting block 3 ensures the stability and accuracy of the first heat dissipation fin 4 during insertion, thereby not only enhancing the stability of the first heat dissipation fin 4, but also preventing the fin from loosening or falling off due to external force.
[0042] The shell 1 is provided with a plurality of air holes 12 at one end of each side wall, which provides sufficient heat dissipation area while maintaining the structural integrity of the shell 1, and the air holes 12 are designed to be inclined upward, which not only helps to guide air flow and improve heat dissipation efficiency, but also reduces the possibility of external pollutants such as dust and moisture entering the interior of the shell 1 to a certain extent, and a plurality of inclined second heat dissipation fins 13 are fixedly arranged on the inner wall of the shell 1, and the inclination direction of the second heat dissipation fins 13 is consistent with that of the air holes 12, forming a coordinated heat dissipation channel. The main function of the second heat dissipation fins 13 is to increase the heat dissipation area and improve the heat dissipation efficiency. When air enters the interior of the shell 1 through the air holes 12, it will flow along the inclination direction of the fins, thereby more effectively taking away the heat on the fins. At the same time, the inclined fins can also block external pollutants such as dust from entering the interior of the shell 1 to a certain extent, protecting the electronic components from damage.
[0043] The shell 1 is provided with a plurality of air holes 12 at one end of each side wall, which provides sufficient heat dissipation area while maintaining the structural integrity of the shell 1, and the air holes 12 are designed to be inclined upward, which not only helps to guide air flow and improve heat dissipation efficiency, but also reduces the possibility of external pollutants such as dust and moisture entering the interior of the shell 1 to a certain extent, and a plurality of inclined second heat dissipation fins 13 are fixedly arranged on the inner wall of the shell 1, and the inclination direction of the second heat dissipation fins 13 is consistent with that of the air holes 12, forming a coordinated heat dissipation channel. The main function of the second heat dissipation fins 13 is to increase the heat dissipation area and improve the heat dissipation efficiency. When air enters the interior of the shell 1 through the air holes 12, it will flow along the inclination direction of the fins, thereby more effectively taking away the heat on the fins. At the same time, the inclined fins can also block external pollutants such as dust from entering the interior of the shell 1 to a certain extent, protecting the electronic components from damage.
[0044] In specific use, the notch of the limiting block 3 is matched with the protrusion or groove structure in the test pile, so as to fix and install the shell 1 in the test pile, one end of the first heat dissipation fin 4 is inserted into the square slot 111 in the slot 11 opposite to the inner wall of the shell 1, so as to ensure that the fin is closely attached to the rubber pad 112 and connected with the third heat dissipation fin 15, and the other end of the first heat dissipation fin 4 penetrates through the side wall of the test pile and extends to the external environment, the insertion end of the data cable plug 2 is gradually inserted into the through hole 531 from the cross slot 51, until it is completely inserted, then the screw block 53 is rotated to make the screw block 53 tightly press the top of the fixed block 5, so that the slot 51 returns to normal and is closely attached to the side wall of the data cable plug 2, then the insertion end of the data cable plug 2 is inserted and arranged in the jack 14, in the working process of the acquisition instrument, part of the heat generated is absorbed on the second heat dissipation fin 13, most of the heat is transferred to the heat conduction sheet 16, then the heat is conducted out through the first heat dissipation fin 4, a small part of the heat is dissipated outward through the air holes 12 and then absorbed and conducted out by the first heat dissipation fin 4, and another part of the heat is transferred to the third heat dissipation fin 15 and conducted out through the first heat dissipation fin 4, so as to realize heat dissipation of the acquisition instrument.
