Description

Technical Field

[0001] This utility model belongs to the field of grounding resistance monitoring technology, specifically relating to a real-time grounding resistance monitoring device. Background Technology

[0002] Grounding resistance refers to the resistance used to connect the grounding electrode and the grounding system in a grounding system. Its function is to conduct current into the ground through grounding resistance, thereby ensuring equipment safety. The magnitude of the grounding resistance affects the grounding effect of the grounding system; generally, a lower resistance value is better. In the petroleum industry, oil storage tanks, as containers for storing oil products, are mainly used in refineries, oil fields, oil depots, and other industries. With the development of chemical technology, the diameter and number of large oil storage tanks are increasing, leading to a greater probability of lightning strikes. Oil tank areas are often built in areas prone to lightning disasters, such as along rivers and coastlines, making the tanks susceptible to lightning strikes and fires. In recent years, there have been several large oil storage tank fires in China caused by lightning strikes, which are closely related to whether the grounding resistance of the oil storage tanks has been properly monitored.

[0003] However, in the existing technology, most grounding resistance monitoring devices are fixed in place during use, and special tools are required for disassembly during maintenance. This makes it too troublesome for staff to inspect or repair them, and it is not convenient to achieve convenient installation, disassembly and maintenance of the monitoring device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a real-time grounding resistance monitoring device to solve the problem that the grounding resistance monitoring device in the prior art is fixed and cannot be disassembled for maintenance.

[0005] To solve the above-mentioned technical problems, the present invention provides a real-time grounding resistance monitoring device, including a housing and a grounding resistance monitoring device. The housing has an internal mounting plate, and the mounting plate has fixed seats at both ends on its front side. The grounding resistance monitoring device is mounted on the fixed seats, and the grounding resistance monitoring device has connecting blocks at both ends. The connecting blocks have grooves, and the fixed seats have quick-release mechanisms. The connecting blocks are inserted into the quick-release mechanisms.

[0006] The quick-connect mechanism includes a movable buckle, which is rotatably connected to the fixed base via a rotating shaft. A limit block is provided at one end of the movable buckle corresponding to the groove, and a linkage is fixedly provided at the end of the movable buckle away from the limit block, so that the movable buckle can rotate around the rotating shaft under the restriction of the linkage to lock and open the movable buckle, thereby detachably connecting the grounding resistance monitoring device to the mounting plate.

[0007] The linkage component includes a push rod and an elastic element, which are symmetrically arranged on both sides of the movable buckle away from the limiting block. One end of the push rod is fixedly connected to the movable buckle, and the other end passes through the fixed base and is connected to a button.

[0008] The elastic element is a return spring and a sleeve. The return spring is installed inside the sleeve. One end of the return spring is fixedly connected to the movable buckle, and the other end is fixedly connected to the inner wall of the fixed seat. In the closed state, the elastic force of the return spring keeps the movable buckle closed.

[0009] The fixing base has a limiting opening on its front side, and the size of the limiting opening corresponds to that of the connecting block.

[0010] The grounding resistance monitoring device has a transmission line fixedly connected to its side, and the end of the transmission line passes through the housing and is fixedly connected to a probe.

[0011] The box body has an opening on its side, and a door panel is rotatably connected to the inner wall of the opening. The size of the door panel corresponds to the opening.

[0012] The side of the box is rotatably connected to a rotating block, which is located above the door panel, and a stop bar is fixedly installed on the surface of the rotating block.

[0013] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0014] This utility model is equipped with a quick-release mechanism. The connecting blocks at both ends of the grounding resistance monitoring device are inserted into the quick-release mechanism to form a snap-locking form with the movable buckle. The movable buckle is locked or opened by the rotating shaft, linkage and elastic parts, so as to fix and disassemble the grounding resistance monitoring device body. It is convenient to operate and quick to disassemble and assemble without the need for special tools, which facilitates the subsequent maintenance of the grounding resistance monitoring device body.

[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] An embodiment of this utility model provides a real-time grounding resistance monitoring device, including a housing 1 and a grounding resistance monitoring device 2. The housing 1 is provided with a mounting plate 3 inside, and the mounting plate 3 is provided with fixing seats 4 at both ends of its front side. The grounding resistance monitoring device 2 is mounted on the fixing seats 4, and the grounding resistance monitoring device 2 is provided with connecting blocks 201 at both ends. The connecting blocks 201 are provided with grooves 202. The fixing seats 4 are provided with a quick-release mechanism 5, and the connecting blocks 201 are inserted into the quick-release mechanism 5.

[0023] It should be noted that the grounding resistance monitoring device is a device in the prior art that can monitor the working status of the grounding resistance. Staff can remotely monitor the working status of the grounding resistance through the grounding resistance monitoring device. The working principle of the grounding resistance monitoring device is well known in the prior art, so it will not be described in detail in this technical solution.

[0024] The quick-connect mechanism 5 includes a movable buckle 501, which is rotatably connected to the fixed base 4 via a rotating shaft 502. A limiting block 503 is provided at one end of the movable buckle 501 corresponding to the groove 202, and a rotational space is provided between the limiting block 503 and the groove 202 for the movable buckle 501 to rotate. A linkage component is fixedly provided at the end of the movable buckle 501 away from the limiting block 503. The linkage component includes a push rod 504, a return spring 505, and a sleeve 506. The push rod 504, the return spring 505, and the sleeve 506 are symmetrically arranged on both sides of the end of the movable buckle 501 away from the limiting block 503. One end of the push rod 504 is fixedly connected to the movable buckle 501, and the other end passes through the fixed base 4 and is connected to a button 507. A return spring 505 is provided inside the sleeve 506. One end of the return spring 505 is fixedly connected to the movable buckle 501, and the other end is fixedly connected to the inner wall of the fixed base 4.

[0025] The movable buckle 501 rotates around the rotating shaft 502 under the constraint of the linkage, thereby locking and unlocking the movable buckle 501, and thus detachably installing the grounding resistance monitoring device 2 onto the mounting plate 3. In the locked state, the elastic force of the return spring 505 keeps the movable buckle 501 closed, thereby causing the limiting block 503 to engage with the connecting block 201, thus restricting and fixing the grounding resistance monitoring device 2, while the sleeve 506 ensures that the return spring 505 can extend and retract along the pushing direction of the push rod 504.

[0026] A limiting opening 505 is provided on the front of the fixing base 4. The size of the limiting opening 508 corresponds to that of the connecting block 201, so that the connecting block 201 can be disengaged from the quick release mechanism 4 and taken out from the limiting opening 508 when the movable buckle is opened.

[0027] A transmission line 6 is fixedly connected to the side of the grounding resistance monitoring device 2, and the end of the transmission line 6 passes through the housing 1 and is fixedly connected to a probe 7.

[0028] An opening is provided on the side of the box body 1, and a door panel 101 is rotatably connected to the inner wall of the opening. The size of the door panel 101 corresponds to the opening. A rotating block 102 is rotatably connected to the side of the box body 1. The rotating block 102 is positioned above the door panel 101, and a stop bar 103 is fixedly provided on the surface of the rotating block 102. Rotating the stop bar 103 drives the rotating block 102, thereby opening the rotating door panel 101.

[0029] The working principle of this utility model is as follows:

[0030] When the ground resistance monitoring device needs to be disassembled and repaired, first rotate the stop lever 103 to drive the rotating block 102, and the rotating door panel 101 will open. Then, by pressing the button 507, the push rod 504 will be pushed up or down, causing the movable buckle 501 to rotate along the rotating shaft 502, which will cause the limit block 503 on the movable buckle 501 to disengage from the groove 202 in the connecting block 201. Thus, the ground resistance monitoring device 2 can be detached from the fixed base 4 and disassembled, completing the disassembly of the ground resistance monitoring device. After that, maintenance or replacement can be carried out, saving manpower and time costs. The ground resistance monitoring device can be easily disassembled, which facilitates the inspection and maintenance of the monitoring device. Problems can be detected and dealt with in a timely manner, ensuring the normal operation of the equipment and reducing downtime.

[0031] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
