Description

Technical Field

[0001] The utility model relates to the field of test structures, in particular to a test pile for cathodic protection detection. Background Art

[0002] The cathodic protection test pile is an essential device in the cathodic protection system of long-distance pipelines, mainly used for kilometer indication of pipelines, detection of cathodic protection effects and operating parameters, and is a device for monitoring parameters such as potential and current of the cathodic protection system. Since long-distance pipelines are often installed outdoors, the cathodic protection detection test piles also need to be installed outdoors.

[0003] Since the cathodic protection detection test piles are installed outdoors, most of them use positioning nails arranged on the lower side of the device and then directly insert the positioning nails into the soil for positioning. Once facing relatively hard soil, it is difficult to insert, making the installation inconvenient. Therefore, a test pile for cathodic protection detection is proposed to solve the above problems. Content of the Utility Model

[0004] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows: A test pile for cathodic protection detection described in the utility model includes a mounting block, a test pile body is fixedly connected to the upper side of the mounting block, a mounting screw rod is movably connected inside the mounting block, a square plate is threadedly connected to the outside of the mounting screw rod, a square groove is opened inside the mounting block, the square groove and the square plate are slidably connected, a circular frame clamping plate is rotatably connected inside the square plate, a positioning nail is fixedly connected to the outside of the circular frame clamping plate, the positioning nail and the square plate are rotatably connected, a connecting rod is fixedly connected to the inside of the positioning nail, a connecting groove is opened inside the mounting screw rod, and the connecting groove and the connecting rod are slidably connected. In this step, by setting the mounting screw rod and the square plate, the user can use an electric screwdriver to twist the mounting screw rod, so that the square plate can stably push the positioning nail into the soil, making the installation of the positioning nail more convenient. By setting the connecting rod and the connecting groove, when the mounting screw rod drives the square plate to push the positioning nail to move, the mounting screw rod will simultaneously drive the connecting rod to rotate. Through the fixed connection between the connecting rod and the positioning nail, the positioning nail rotates while moving, so as to facilitate the positioning nail to be screwed into the soil and improve the convenience of its installation.

[0006] Preferably, sliding grooves are provided on the inner side of the connecting rod and the surface of the positioning nail. A spring plate is slidably connected inside the sliding groove, and an inclined plate is fixedly connected to the outer side of the spring plate. By setting the spring plate in this step, when the positioning nail is completely screwed into the soil, the spring plate will pop out from the inside of the positioning nail and insert into the soil, thereby further positioning the device and improving the stability of the device positioning. Through the setting of the inclined plate, due to the inclination angle of the inclined plate, the inclined plate is convenient for pushing aside the soil when moving, so that the spring plate can be more easily inserted into the soil, improving the fixing stability of the device.

[0007] Preferably, a guardrail is fixedly connected to the upper side of the mounting block, and a guard plate is fixedly connected to the upper side of the guardrail. By setting the guardrail and the guard plate in this step, the test pile body can be separated from the outer environment through the cooperation of the guardrail and the guard plate, so as to protect the test pile body when it is impacted, improving the stability of the device during use.

[0008] Preferably, a movable fan blade is rotatably connected to the inner side of the guard plate, a rotating plate is fixedly connected to the lower side of the movable fan blade, and a cleaning brush is fixedly connected to the lower side of the rotating plate. By setting the movable fan blade and the cleaning brush in this step, when it is windy or rainy, the wind will blow the movable fan blade to rotate. The movable fan blade drives the rotating plate and the cleaning brush to rotate, so as to clean the surface of the test pile body through the cleaning brush, reducing the influence of dust on the test pile body and improving the practicability of the device.

[0009] Preferably, a limiting plate is fixedly connected to the lower side of the mounting block, and the limiting plate and the square plate are used in cooperation. By setting the limiting plate in this step, when the square plate moves to the maximum position, the limiting plate can block it, so that the square plate will not be separated from the mounting screw rod, improving the stability of the device during use.

[0010] Preferably, a counterweight groove is provided inside the mounting block, and the counterweight groove and the positioning nail are used in cooperation. By setting the counterweight groove in this step, after the device is installed, heavy objects such as stones in the wild can be moved and placed inside the counterweight groove, further increasing the weight of the mounting block, thereby providing more pressure on the positioning nail and improving the stability of the device installation.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. By setting the mounting screw rod and the square plate in the present utility model, the user can screw the mounting screw rod with an electric screwdriver, so that the square plate can stably push the positioning nail into the soil, making the installation of the positioning nail more convenient. By setting the connecting rod and the connecting groove, when the mounting screw rod drives the square plate to push the positioning nail to move, the mounting screw rod will simultaneously drive the connecting rod to rotate. Through the fixed connection between the connecting rod and the positioning nail, the positioning nail rotates while moving, thus facilitating the positioning nail to be screwed into the soil and improving the convenience of its installation;

[0013] 2. The utility model improves the positioning stability of the device by setting a spring plate. After the positioning pin is completely screwed into the inner side of the soil, the spring plate will pop out from the inner side of the positioning pin and insert into the inner side of the soil, thereby further positioning the device. Through the setting of the inclined plate, due to the inclined angle of the inclined plate, the inclined plate is convenient for pushing aside the soil when moving, so that the spring plate can be more easily inserted into the inner side of the soil, improving the fixing stability of the device.

Detailed Embodiment

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] The following gives specific embodiments.

[0023] Please refer to Figures 1-5 As shown, a test pile for cathodic protection detection includes a mounting block 1. A test pile body 2 is fixedly connected to the upper side of the mounting block 1. An installation screw rod 3 is movably connected inside the mounting block 1. A square plate 4 is threadedly connected to the outside of the installation screw rod 3. A square groove 5 is formed inside the mounting block 1. The square groove 5 and the square plate 4 are slidably connected. A circular frame clamping plate 6 is rotatably connected inside the square plate 4. A positioning nail 7 is fixedly connected to the outside of the circular frame clamping plate 6. The positioning nail 7 and the square plate 4 are rotatably connected. A connecting rod 8 is fixedly connected to the inside of the positioning nail 7. A connecting groove 9 is formed inside the installation screw rod 3. The connecting groove 9 and the connecting rod 8 are slidably connected. In this step, by setting the installation screw rod 3 and the square plate 4, the user can use an electric screwdriver to turn the installation screw rod 3, so that the square plate 4 can stably push the positioning nail 7 into the soil, making the installation of the positioning nail 7 more convenient. By setting the connecting rod 8 and the connecting groove 9, when the installation screw rod 3 drives the square plate 4 to push the positioning nail 7 to move, the installation screw rod 3 will also drive the connecting rod 8 to rotate. Through the fixed connection between the connecting rod 8 and the positioning nail 7, the positioning nail 7 rotates while moving, so as to facilitate the positioning nail 7 to be screwed into the soil, improving the convenience of its installation.

[0024] Further, as Figure 3 and Figure 4 shown, sliding grooves 10 are formed on the inner side of the connecting rod 8 and the surface of the positioning nail 7. A spring plate 11 is slidably connected inside the sliding grooves 10. An inclined plate 12 is fixedly connected to the outside of the spring plate 11. In this step, by setting the spring plate 11, when the positioning nail 7 is completely screwed into the soil, the spring plate 11 will pop out from the inside of the positioning nail 7 and insert into the soil, thereby further positioning the device and improving the stability of the device positioning. Through the setting of the inclined plate 12, due to the inclination angle of the inclined plate 12, the inclined plate 12 is convenient to push away the soil when moving, so that the spring plate 11 can be more easily inserted into the soil, improving the fixing stability of the device.

[0025] Further, as Figure 1 shown, a guardrail 13 is fixedly connected to the upper side of the mounting block 1. A guard plate 14 is fixedly connected to the upper side of the guardrail 13. In this step, by setting the guardrail 13 and the guard plate 14, the test pile body 2 can be separated from the outside environment through the cooperation of the guardrail 13 and the guard plate 14, so as to protect the test pile body 2 when it is impacted, improving the stability of the device during use.

[0026] Further, as Figure 5As shown, an active fan blade 15 is rotatably connected to the inner side of the protection plate 14. A rotating plate 16 is fixedly connected to the lower side of the active fan blade 15, and a cleaning brush 17 is fixedly connected to the lower side of the rotating plate 16. Through the arrangement of the active fan blade 15 and the cleaning brush 17 in this step, when it is windy or rainy, the wind will blow the active fan blade 15 to rotate. The rotating plate 16 and the cleaning brush 17 are driven by the active fan blade 15 to rotate, so that the surface of the test pile body 2 is cleaned by the cleaning brush 17, reducing the influence of dust on the test pile body 2 and improving the practicability of the device.

[0027] Further, as Figure 3 and Figure 2 shown, a limiting plate 18 is fixedly connected to the lower side of the mounting block 1. The limiting plate 18 and the square plate 4 are used in cooperation. By setting the limiting plate 18 in this step, when the square plate 4 moves to the maximum position, it can be blocked by the limiting plate 18, so that the square plate 4 will not be separated from the mounting screw rod 3, improving the stability of the device during use.

[0028] Further, as Figure 1 shown, a counterweight groove 19 is formed inside the mounting block 1. By setting the counterweight groove 19 in this step, after the device is installed, heavy objects such as stones in the wild can be moved and placed inside the counterweight groove 19, so that the weight of the mounting block 1 is further increased, thereby providing more pressure on the positioning pin 7 and improving the stability of the device installation.

[0029] Working principle: Move the mounting block 1 to a suitable position, and then rotate the mounting screw rod 3 with an electric screwdriver. Due to the threaded connection between the mounting screw rod 3 and the square plate 4 and the restriction of the square plate 4 by the square groove 5, the square plate 4 moves downward. The positioning pin 7 is driven by the square plate 4 to move downward. At the same time, the connecting groove 9 is driven to rotate by the mounting screw rod 3. The connecting rod 8 is driven to rotate by the connecting groove 9. Due to the fixed connection between the connecting rod 8 and the positioning pin 7, the positioning pin 7 moves downward and rotates at the same time, and then is screwed into the soil. When the positioning pin 7 moves to a sufficient depth in the soil, the spring plate 11 inside the connecting rod 8 will move out of the connecting groove 9, and then the spring plate 11 moves outward under the push of its own elasticity. The inclined plate 12 is pushed by the spring plate 11 to move, so that the inclined plate 12 pushes aside the soil, and the spring plate 11 can be inserted into the soil to complete the installation and positioning. When there is wind flowing in the wild, the wind will blow the active fan blade 15 to rotate, causing the active fan blade 15 to drive the rotating plate 16 to rotate. The cleaning brush 17 is driven by the rotating plate 16 to move and clean the test pile body 2.
