Description

Technical Field

[0001] This utility model relates to the field of electrode technology, specifically to an anti-detachment plug-in electrode. Background Technology

[0002] A reference electrode is an electrode used for comparison when measuring electrode potential. It is used to observe and measure the potential of an indicator electrode or working electrode. The electrode reaction occurring on a reference electrode must be a single, reversible reaction with a high exchange current density and a stable electrode potential. The stability of the reference electrode makes it crucial as an electrical reference point and for measuring the potential of other metals located in soil or water. Reference electrodes are suitable for measuring the potential of buried or underwater pipelines.

[0003] Chinese Patent Publication No. CN215768173U discloses a pluggable reference electrode for cathodic protection. The electrode wire is connected or disconnected by a reciprocating conductive pluggable block, forming a pluggable structure. This makes it easy to use, reduces the impact of current signal noise on the entire detection equipment, and ensures conductivity.

[0004] Although the aforementioned patent can enable the connection or disconnection between the conductive plug and the electrode wire, the conductive plug is limited by the second spring and the limiting protrusion. However, the contact area between the limiting protrusion and the conductive plug is small, and the conductive plug is easily detached from the fiber protrusion due to vibration. This can lead to poor contact or power failure between the wire plug and the electrode wire. Utility Model Content

[0005] The purpose of this invention is to provide an anti-dislodgement pluggable electrode to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An anti-dislodgement pluggable electrode includes an electrode body, a connecting tube fixedly connected to the bottom end of the electrode body, a glass tube fixedly inserted through the connecting tube, a porous ceramic fixedly connected to the bottom end of the glass tube, a cavity communicating with the inside of the connecting tube at the top end of the electrode body, a fixing block disposed inside the cavity, an electrode wire embedded and fixed inside the fixing block, the bottom end of the electrode wire extending to the bottom of the glass tube, a pluggable mechanism for contacting and separating from the electrode wire disposed inside the cavity, an anti-dislodgement mechanism screwed onto the top end of the electrode body, and a wire passing through the anti-dislodgement mechanism disposed inside the pluggable mechanism.

[0008] Furthermore, the insertion and removal mechanism includes a movable ring that slides inside the chamber, and an insertion and removal block is detachably connected inside the movable ring. A cylindrical groove is formed on the bottom surface of the insertion and removal block, and a spring is fixedly connected inside the cylindrical groove. One end of the spring is fixedly connected to a contact block that is electrically connected to the wire.

[0009] Furthermore, the top surface of the plug-in block is fixedly connected to an installation block, and the installation block and the moving ring are fastened together by multiple bolts.

[0010] Furthermore, the inner wall of the chamber has two symmetrical grooves, the inner bottom surface of the grooves is fixedly connected to a sliding rod, and the outer wall of the movable ring is fixedly connected to two symmetrical limiting blocks that slide through the sliding rod at the corresponding position.

[0011] Furthermore, a spring is fixedly connected to the outer side of the slide rod on the top surface of the limiting block at the corresponding position.

[0012] Furthermore, the outer wall of the chamber is provided with a thread at its top end, and the anti-detachment mechanism includes a threaded sleeve that is screwed into the inner top end of the chamber. A threaded post is screwed into the inside of the threaded sleeve, and a plurality of connecting rods are fixedly connected at equal angles to the bottom end of the threaded post. A fixing ring is fixedly connected between the bottom ends of the plurality of connecting rods.

[0013] Furthermore, the bottom end of the threaded sleeve is rotatably connected to a connecting ring that is fixedly connected to two springs, the top end of the outer wall of the threaded sleeve is fixedly connected to a rotating ring, and the top end of the threaded column is fixedly connected to a screw block that passes through the wire.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The device uses an anti-detachment mechanism to squeeze or release the pressure on the insertion and removal mechanism, so that the insertion and removal mechanism is in close contact with or separated from the electrode wire, thereby realizing the on and off of the electrode wire. Since the anti-detachment mechanism is screwed to the top of the electrode body, it can prevent the insertion and removal mechanism from detaching from the electrode wire, which would lead to poor contact or power failure.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 In this embodiment of the present invention, an anti-detachment pluggable electrode includes an electrode body 1. A connecting tube 2 is fixedly connected to the bottom end of the electrode body 1. A glass tube 3 is fixedly inserted through the inside of the connecting tube 2. A porous ceramic 4 is fixedly connected to the bottom end of the glass tube 3. A cavity 11 communicating with the inside of the connecting tube 2 is opened at the top end of the electrode body 1. A fixing block 5 is provided inside the cavity 11. An electrode wire 51 is embedded and fixed inside the fixing block 5, and the bottom end of the electrode wire 51 extends to the bottom of the glass tube 3. A pluggable mechanism 6 that contacts and separates from the electrode wire 51 is provided inside the cavity 11. An anti-detachment mechanism 7 is screwed onto the top end of the electrode body 1. A wire 8 that passes through the anti-detachment mechanism 7 is provided inside the pluggable mechanism 6.

[0025] Specifically, first, the fixing block 5, through which the electrode wire 51 is fixed, is placed at the bottom of the chamber 11. Then, after positioning the insertion / removal mechanism 6 and the anti-detachment mechanism 7, the insertion / removal mechanism 6 is placed inside the chamber 11, and the anti-detachment mechanism 7 is screwed onto the inner top of the chamber 11. The anti-detachment mechanism 7 presses against the insertion / removal mechanism 6, making the insertion / removal mechanism 6 in close contact with the electrode wire 51. Then, by connecting the wire 8 to an external power source, the electrode wire 51 can be energized. When it is necessary to de-energize the electrode wire 51, the anti-detachment mechanism 7 releases the pressure on the insertion / removal mechanism 6, causing the insertion / removal mechanism 6 to move upward and detach from the electrode wire 51, thereby de-energizing. This device uses the anti-detachment mechanism 7 to press or release the pressure on the insertion / removal mechanism 6, making the insertion / removal mechanism 6 in close contact with or separate from the electrode wire 51, thereby realizing the energization and de-energization of the electrode wire 51. Since the anti-detachment mechanism 7 is screwed onto the top of the electrode body 1, it can prevent the insertion / removal mechanism 6 from detaching from the electrode wire 51, thus preventing poor contact or de-energization.

[0026] Example 1

[0027] like Figure 4 and Figure 5 As shown, in this embodiment, the insertion and removal mechanism 6 includes a movable ring 61 that slides inside the chamber 11. An insertion and removal block 62 is detachably connected inside the movable ring 61. A cylindrical groove 64 is provided on the bottom surface of the insertion and removal block 62. A spring 65 is fixedly connected inside the cylindrical groove 64. A contact block 66 electrically connected to the wire 8 is fixedly connected to one end of the spring 65. An installation block 63 is fixedly connected to the top surface of the insertion and removal block 62. The installation block 63 and the movable ring 61 are fastened together by multiple bolts. Two symmetrical grooves 12 are provided on the inner wall of the chamber 11. A sliding rod 13 is fixedly connected to the inner bottom surface of the groove 12. Two symmetrical limiting blocks 67 are fixedly connected to the outer wall of the movable ring 61 and slide through the sliding rod 13 at the corresponding positions. A spring 68 is fixedly connected to the top surface of the limiting block 67 and the outer side of the sliding rod 13 at the corresponding position.

[0028] In this embodiment, the insertion block 62 is inserted into the moving ring 61, and the mounting block 63 is fixed to the top surface of the moving ring 61 with bolts. Then, the mounting block 63 is pressed by the anti-detachment mechanism 7, which causes the moving ring 61 to move the insertion block 62 downward until the electrode wire 51 is inserted into the cylindrical groove 64 and makes close contact with the contact block 66, compressing the spring 65. The detachable connection between the mounting block 63 and the moving ring 61 facilitates the replacement of the insertion block 62 when it is damaged in the future.

[0029] Example 2

[0030] like Figure 6As shown, in this embodiment, the top of the outer wall of the chamber 11 is threaded. The anti-detachment mechanism 7 includes a threaded sleeve 71 that is screwed into the top of the inner wall of the chamber 11. A threaded post 72 is screwed into the inside of the threaded sleeve 71. A plurality of connecting rods 73 are fixedly connected at equal angles to the bottom of the threaded post 72. A fixing ring 74 is fixedly connected between the bottom ends of the plurality of connecting rods 73. A connecting ring that is fixedly connected to two springs 68 is rotatably connected to the bottom of the threaded sleeve 71. A rotating ring 75 is fixedly connected to the top of the outer wall of the threaded sleeve 71. A screw block 76 that passes through the wire 8 is fixedly connected to the top of the threaded post 72.

[0031] In this embodiment, by screwing the threaded sleeve 71 into the top of the electrode body 1, and then passing the wire 8 through the threaded post 72 and screwing the threaded post 72 into the threaded sleeve 71, the rotating threaded post 72 can drive the fixing ring 74 to move down through multiple connecting rods 73. The moving fixing ring 74 can apply pressure to the insertion block 62, causing the insertion block 62 to move down and pull up the two springs 68 until the electrode wire 51 is inserted into the cylindrical groove 64 and makes tight contact with the contact block 66, thereby realizing the energization of the electrode wire 51. Since the threaded sleeve 71 is screwed into the electrode body 1 and the threaded post 72 is screwed into the threaded sleeve 71, it can prevent the contact block 66 from detaching from the electrode wire 51, thus preventing poor contact or power failure.
