When the clamping mechanism clamps the to-be-measured object, probes in the probe group are in contact with the to-be-measured object, and measurement is started; and a data acquisition module electrically connected with the probe group synchronously acquires and records measurement data of the probes. An operator does not need to be close to a to-be-detected object (such as an electrolytic cell cathode explosion block) at a high temperature and a high position, the whole process of clamping, measuring and recording can be completed only through remote control of the rod body, potential safety hazards caused by the fact that the operator climbs to the high position or is close to a heat source are avoided, and the safety of detection operation is improved.

Description

Technical Field

[0001] This application relates to the field of aluminum electrolysis equipment testing technology, and in particular to a cathode explosion block pressure drop measuring device for aluminum electrolysis. Background Technology

[0002] In the electrolytic aluminum production process, electric current is transmitted through a vast series of electrolytic cells. The electrical connection between the cathode steel rod and the aluminum busbar is typically achieved using explosive welding technology. This connection point, commonly known as the "cathode explosion block," directly determines the contact resistance. The voltage drop and Joule heat generated by this contact resistance cause significant energy loss, reduce current efficiency, and in severe cases, may even lead to the melting of the connection point due to localized overheating, resulting in production accidents. Therefore, regular and accurate monitoring of the voltage drop at the cathode explosion block is a crucial step for electrolytic aluminum enterprises to achieve energy conservation, reduce consumption, and ensure safe production.

[0003] Currently, most aluminum companies still use traditional handheld multimeters for contact measurement to test the voltage drop of cathode explosion blocks. In practice, this traditional testing method is labor-intensive and poses significant safety hazards. The cathode explosion block structure in electrolytic cells is often located on the side of the cell, at a certain height above the ground. Testing personnel must press two probes onto the measuring points of the cathode steel rod and the aluminum busbar, respectively. This operation is not only strenuous, but the high temperature around the electrolytic cell also greatly increases the risk of burns to the operator. Furthermore, the elevated working environment itself presents a risk of falls, posing a serious threat to safe production.

[0004] Therefore, how to improve the safety of testing operations is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples.

In addition, various specific examples of processes and materials are provided in this application; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0022] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0023] See Figure 1This application provides a cathode explosion block pressure drop measuring device for electrolytic aluminum, including a rod 5, a clamping mechanism, and an operating handle 6. The clamping mechanism is located at the first end of the rod 5 and is used to clamp the object to be tested. The clamping mechanism is connected to a probe group, which includes a probe 201 for contacting the object to be tested. The probe group is electrically connected to a data acquisition module 4, which is used to collect and record the measurement data of the probe 201. The operating handle 6 is located at the second end of the rod 5. When the operating handle 6 issues a first command, the clamping mechanism is in an open state. When the operating handle 6 issues a second command, the clamping mechanism is in a clamping state, and the probe 201 contacts the object to be tested.

[0024] It should be noted that the aforementioned test object can be an explosive cathode block of an electrolytic cell, meaning that the cathode explosive block voltage drop measuring device for aluminum electrolysis of this application can be used to detect cathode explosive blocks in aluminum electrolysis cells. An explosive cathode block refers to the explosive weld joint connecting the cathode steel rod and the aluminum busbar. Its structural characteristics and spatial position are specific—usually located on the side of the electrolytic cell, at a certain height above the ground, and the size, shape, and relative positional relationship between the explosive block and the test area (the surface of the cathode steel rod and the surface of the aluminum busbar) are relatively fixed. The clamping mechanism dimensions, probe group layout, and overall structural design of this cathode explosive block voltage drop measuring device for aluminum electrolysis are adapted to the aforementioned characteristics of the explosive cathode block, enabling accurate and stable clamping on the explosive cathode block and ensuring that the probes precisely correspond to the measurement points on the cathode steel rod and the aluminum busbar.

[0025] The electrolytic aluminum cathode explosion block pressure drop measuring device (hereinafter referred to as the measuring device) provided by this invention allows the operator to extend the clamping mechanism to the object under test by holding the operating handle 6 and using the rod 5. The operator issues a first command through the operating handle 6 to open the clamping mechanism; after aligning the open clamping mechanism with the object under test, a second command is issued through the operating handle 6 to switch the clamping mechanism to the clamping state, thus stably fixing the measuring device to the object under test. While the clamping mechanism is clamping the object under test, the probe 201 in the probe group contacts the object and begins measurement; the data acquisition module 4, electrically connected to the probe group, synchronously acquires and records the measurement data of the probe 201. Through this operation, the operator does not need to approach the high-temperature, high-altitude object under test (such as the electrolytic cell cathode explosion block), but can remotely control the entire process of clamping, measuring, and recording using only the rod 5. This fundamentally avoids the safety hazards caused by operators climbing to high places or approaching heat sources, thereby improving the safety of the testing operation.

[0026] See Figures 2-4To optimize the above technical solution, the clamping mechanism includes a base 102, at least one gripper 1, an elastic element 202, a transmission element, and a connecting shaft. The base 102 is fixedly connected to the first end of the rod 5, and the connecting shaft is connected to the base 102. The gripper 1 includes a first clamping part 101 and a second clamping part. The first clamping part 101 includes a first clamping end, a first connecting end, and a first force-bearing end. The second clamping part includes a second clamping end, a second connecting end, and a second force-bearing end. The first connecting end and the second connecting end are hinged to the connecting shaft. One end of the elastic element 202 is connected to the first clamping part 101 near the first connecting end, and the other end of the elastic element 202 is connected to the second clamping part near the second connecting end. The transmission element passes through the interior of the rod 5, and the first end of the transmission element is connected to the first force-bearing end and / or the second force-bearing end. The second end of the transmission element is connected to the operating handle 6.

[0027] See Figure 3 , where AA is a cross-sectional view of the gripper.

[0028] Specifically, the first connecting end is located between the first clamping end and the first force-receiving end, and the second connecting end is located between the second clamping end and the second force-receiving end. When the operating handle 6 issues a first command, a driving force is applied to the first force-receiving end and / or the second force-receiving end through the transmission component, overcoming the elastic force of the elastic element 202, causing the first clamping part 101 and / or the second clamping part to rotate around the connecting shaft, and the first clamping end and the second clamping end open. When the operating handle 6 issues a second command, the driving force is released, and the elastic force of the elastic element 202 drives the first clamping part 101 and the second clamping part to rotate in opposite directions, causing the first clamping end and the second clamping end to close and clamp the object to be measured. The design of the elastic element 202 being arranged close to the first connecting end and the second connecting end keeps it away from the clamping end, avoiding interference with the object to be measured. The elastic element 202 can provide a stable clamping force, ensuring that the clamping mechanism remains closed without external force, improving the reliability of clamping. The introduction of the transmission component enables remote control of the opening and closing of the gripper 1, allowing the operator to complete the clamping operation from a safe position on the ground. The base 102 serves as a fixed foundation, ensuring the stability and accuracy of the gripper 1's movement.

[0029] To optimize the above technical solution, the transmission component is a steel wire draw wire, and anti-slip block 104 is arranged on the side of the first clamping end and the second clamping end that are close to each other. When the clamping mechanism is in the clamping state, the first clamping end and the second clamping end are clamped to the object to be tested.

[0030] Specifically, the anti-slip block 104 is arranged on the side where the first clamping end and the second clamping end are close to each other, that is, the part that is in direct contact with the object to be measured during clamping. It is used to increase the friction between the first clamping end and the second clamping end and the object to be measured, and to prevent the device from sliding or shifting relative to the object to be measured after clamping.

[0031] Specifically, when the operating handle 6 issues a first command, the internal mechanism of the operating handle 6 pulls the steel wire, which is tightened and applies tension to the connected force-bearing ends (the first force-bearing end and / or the second force-bearing end). This tension overcomes the elastic force of the elastic element 202, causing the gripper 1 to open. When the operating handle 6 issues a second command, the steel wire relaxes, and the elastic force of the elastic element 202 drives the gripper 1 to close. At this time, the anti-slip block 104, located inside the first and second gripping ends, is in close contact with the surface of the object to be measured, and the device is stably fixed to the object through friction. The anti-slip block 104 is usually made of an elastomer material with a high coefficient of friction and high temperature resistance, such as silicone or rubber, to adapt to the high-temperature environment around the electrolytic cell. As a transmission component, the steel wire can reliably transmit the operating action of the operating handle 6 to the gripper 1 at the far end, and its flexibility allows it to adapt to the bending or extension of the rod 5, and the transmission path is not limited by the structure of the rod 5. The anti-slip block 104 enhances the connection stability between the clamping mechanism and the object to be measured. Even under vibration or external force interference, the measuring device can maintain a fixed position, ensuring that the contact state between the probe 201 and the object to be measured is not affected, thereby further improving the safety of operation.

[0032] To optimize the above technical solution, the clamping mechanism includes a first clamp and a second clamp, which are arranged side by side on the connecting shaft. The object to be measured includes a region to be measured. When the first clamping end and the second clamping end of the first clamp are in the clamping state, they abut against the first side of the region to be measured. When the second clamping end and the first clamping end of the second clamp are in the clamping state, they abut against the second side of the region to be measured. The first side and the second side are arranged opposite to each other.

[0033] Specifically, when the clamping mechanism is in the open state, both the first and second clamping ends of the first and second jaws are in the open position. The operator aligns the measuring device with the object to be measured, positioning the area to be measured between the first and second jaws. Upon issuing the second command, the first and second jaws close simultaneously. The first and second clamping ends of the first jaw abut against the first side of the area to be measured, and the first and second clamping ends of the second jaw abut against the second side of the area to be measured, thus fixing the measuring device to the object from both sides. The first and second jaws are arranged side-by-side on the same connecting shaft, and their opening and closing actions are synchronized, ensuring a balanced and uniform distribution of clamping force.

[0034] The first and second grippers are arranged side by side and clamp the first and second sides of the area to be measured, respectively, forming a symmetrical clamping structure. This ensures that the clamping force is evenly distributed on both sides of the object to be measured, avoiding the skewing or shaking that may be caused by clamping on one side, thus providing a reliable mechanical basis for subsequent accurate measurement.

[0035] To optimize the above technical solution, the probe group is installed on the base 102 and located between the first gripper and the second gripper. The installation position of the probe group on the base 102 corresponds to the area to be measured, and is used to contact the area to be measured when the clamping mechanism is in the clamping state.

[0036] Specifically, when the first and second grippers close to hold the object to be measured, they abut against the first and second sides of the area to be measured, respectively, stabilizing and fixing the measuring device. Simultaneously, the probe assembly, mounted on the base 102 and located between the first and second grippers, is precisely aligned with the area to be measured due to its pre-designed position. As the first and second grippers close, the probe 201 in the probe assembly contacts the area to be measured, initiating the measurement. Throughout the process, the probe assembly remains fixed to the base 102 and does not move with the movement of the first and second grippers, ensuring the alignment accuracy between the probe 201 and the area to be measured. The space between the first and second grippers provides the perfect mounting position for the probe assembly, allowing the probe 201 to accurately correspond to the area to be measured, achieving the ideal layout of "two-point clamping and intermediate measurement," ensuring both clamping stability and measurement accuracy.

[0037] To optimize the above technical solution, the base 102 is provided with an installation groove, the probe 201 is disposed inside the installation groove, and an elastic reset member 103 is provided between the probe 201 and the bottom of the installation groove. The elastic reset member 103 is used to apply axial elastic force to the probe 201.

[0038] Specifically, the mounting groove provides precise guidance and positioning for the probe 201, ensuring that the probe 201 can only move axially and maintain perpendicular contact with the object to be measured. An elastic reset element 103 (such as a compression spring) is disposed between the rear end of the probe 201 and the bottom of the mounting groove, continuously applying a forward elastic force to the probe 201 to keep the probe 201 in the extended state.

[0039] When the clamping mechanism is in the open state, the elastic force of the elastic reset member 103 keeps the probe 201 extended out of the mounting groove. When the gripper 1 closes to clamp the object to be measured, the tip of the probe 201 first contacts the surface of the object. As the gripper 1 continues to close, the probe 201 is pressed back into the mounting groove by the surface of the object, compressing the elastic reset member 103 at the rear end. The elastic reset member 103 generates a reverse elastic force after being compressed, keeping the tip of the probe 201 in close elastic contact with the surface of the object. Due to the presence of the elastic reset member 103, even if there are slight unevenness or oxide layers on the surface of the object, the probe 201 can maintain good contact with it under the action of constant elastic force. The setting of the elastic reset member 103 solves the problem of unstable contact resistance caused by uneven manual force in traditional handheld measurement. The constant elastic force provided by the elastic reset member 103 ensures that the contact pressure between the probe 201 and the object to be measured remains consistent in each measurement, significantly improving the repeatability and accuracy of the measurement.

[0040] To optimize the above technical solution, the measuring device also includes a wire 3, which is inserted inside the rod 5. The data acquisition module 4 is fixedly connected to the operating handle 6. The first end of the wire 3 is connected to the probe 201, and the second end of the wire 3 is connected to the data acquisition module 4.

[0041] Specifically, when probe 201 contacts the object to be measured, the voltage signal (or other electrical signal) sensed by the tip of probe 201 is transmitted through the wire 3 connected to it. Wire 3 passes through the internal cavity of rod 5, extending from the first end to the second end of rod 5, transmitting the signal to the data acquisition module 4 fixedly connected to the operating handle 6. After receiving the signal, the data acquisition module 4 performs analog-to-digital conversion, calculation processing, and stores the measurement results in its internal memory. Operators can view the measurement data or trigger the data recording function through the interactive interface on the operating handle 6. The wire 3 is completely concealed within the rod 5, avoiding the exposure of external cables and the risk of external cables being hooked, tangled, or damaged in complex field environments, thus improving the durability and operational safety of the measuring device. The data acquisition module 4 is fixedly connected to the operating handle 6, allowing operators to view the measurement results in real time without needing to carry additional instruments. This integrated design simplifies the on-site operation process; operators only need to hold one measuring device to complete the entire process of clamping, measuring, recording, and viewing, without switching between multiple devices, thereby improving detection efficiency.

[0042] To optimize the above technical solution, the rod body 5 includes at least two pipe sections, and the ends of the two adjacent pipe sections are threaded together or fixedly connected by locking bolts. When the ends of the two adjacent pipe sections are fixedly connected by locking bolts, the pipe has multiple mounting holes, and the multiple mounting holes are evenly arranged along the axial direction of the pipe.

[0043] Specifically, rod 5 is a telescopic structure. The operator adjusts the total length of rod 5 according to the actual height of the object to be measured (such as the cathode explosion block of an electrolytic cell). For threaded pipes, the length can be adjusted by changing the thread engagement depth by tightening the pipe. For bolted pipes, loosen the bolts, connect two or more pipes, extend or retract the pipes until the total length of rod 5 reaches the desired length, and then tighten the bolts to fix the length of rod 5. Multiple mounting holes are evenly arranged axially, providing multiple fixed length settings for quick adjustment and accurate positioning. After adjustment, rod 5 maintains a fixed length, allowing the operator to extend the clamping mechanism to the height of the object to be measured. The telescopic rod 5 design allows the same measuring device to adapt to objects of different heights and positions, greatly improving the versatility and applicability of the measuring device. For electrolytic cell testing scenarios, the height of different electrolytic cells or different positions within the same electrolytic cell may vary. The telescopic rod 5 allows operators to complete the testing of all measurement points without changing equipment, thereby improving testing efficiency.

[0044] See Figure 5 To optimize the above technical solution, the operating handle 6 is equipped with a data recording button, which is electrically connected to the data acquisition module 4 and is used to trigger the data acquisition module 4 to perform measurement and recording functions; the operating handle 6 is also equipped with a display screen 604 for real-time display of measurement data.

[0045] Specifically, after the operator fixes the clamping mechanism to the object to be tested, they press the data recording button on the operating handle 6. Pressing the data recording button sends a trigger signal to the data acquisition module 4. Upon receiving the trigger signal, the data acquisition module 4 immediately performs a measurement, acquiring the electrical signal sensed by the current probe group, processing it, and storing the measurement result in its internal memory. Simultaneously, the measurement result is displayed in real-time on the display screen 604 on the operating handle 6 for on-site confirmation by the operator. The operator can determine the validity of the measurement based on the data on the display screen 604, and repeat the measurement or record multiple data points if necessary. The data recording button improves the convenience of testing, simplifies the operation process, and allows the operator to focus on clamping and positioning operations without being distracted by complex instruments. The introduction of the display screen 604 provides instant feedback on the measurement results, allowing the operator to confirm the validity of the data on-site, promptly identify anomalies, and remeasure, thereby improving testing efficiency.

[0046] Furthermore, the operating handle 6 can control the opening and closing of the gripper 1 via an action control switch 602 mounted thereon. The action control switch 602 is either a slider that can slide axially along the operating handle 6 or a trigger structure that can rotate around a fulcrum. The action control switch 602 is fixedly connected to one end of a steel wire cable. The steel wire cable passes through the internal cavity of the rod body 5, and its other end is fixedly connected to the first force-bearing end of the first clamping part 101 and / or the second force-bearing end of the second clamping part. When the operator operates the action control switch 602 in the first direction (e.g., pulling backward or pressing), the action control switch 602 causes the steel wire cable to move towards the operating handle 6. The steel wire cable is tightened and applies a pulling force towards the force-bearing end connected to it in the direction of the operating handle 6. This pulling force causes the first clamping part 101 and / or the second clamping part to rotate around the connecting shaft, overcoming the elastic force of the elastic element 202, thereby opening the first and second clamping ends. When the operator releases the action control switch 602, the steel wire pull cable loosens, and the elastic force of the elastic element 202 drives the first clamping part 101 and the second clamping part to rotate in opposite directions, causing the first clamping end and the second clamping end to automatically reset to the closed state. During the closing process of the gripper 1, the force-bearing end drives the steel wire pull cable and the action control switch 602 to move in the opposite direction to the first direction, causing the action control switch 602 to automatically reset to the initial position.

[0047] To optimize the above technical solution, the operating handle 6 is provided with a storage compartment 603 inside, which is used to store the wire 3; the outer surface of the operating handle 6 is covered with an anti-slip sleeve 601; the outer surface of the base 102 is embedded with a level 8 and an illumination element 7, the level 8 is used to display the angle of the rod 5, and the illumination element 7 is used to provide illumination.

[0048] Specifically, when not in use or during transportation, excess wires 3 can be stored in the storage compartment 603 inside the operating handle 6, preventing them from scattering and tangling, keeping the measuring device neatly stored and easy to carry, and preventing damage to the wires 3 during transportation and use. During operation, the operator holds the operating handle 6 covered with an anti-slip sleeve 601, which provides a comfortable grip and reliable friction to prevent slippage. When working at the bottom of an electrolytic cell in low light or at night, the lighting unit 7 can be turned on to provide illumination to the operating area, making it easier for the operator to align the object to be measured. During clamping, the operator can observe the level 8 on the base 102 to determine the angle of the rod 5, adjust the grip to keep the clamping mechanism level, and ensure that the probe 201 contacts the surface of the object to be measured at the optimal angle, guaranteeing measurement accuracy.

Other fields refer to any field other than the field of aluminum electrolysis equipment testing technology.
