[0048] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0049] See also Figures 1 to 4 As shown;

[0050] This embodiment discloses an intelligent energy isolation monitoring device, which is installed at a pipeline blind plate or valve and is used to detect the locking state of the pipeline blind plate or valve. The monitoring device includes:

[0051] Lock structure 1 and unlocking handle structure 2;

[0052] The unlocking handle structure 2 has an unlocking handle that can be pressed and moved horizontally for a certain distance;

[0053] The lock structure 1 comprises:

[0054] Flange nut sleeve main body 101 and flange nut sleeve matching body 102;

[0055] The flange nut sleeve matching body 102 is connected with a locking tooth 103 extending in the horizontal direction, and the locking tooth 103 is matched with a locking tongue 104;

[0056] The lock tongue 104 is in contact with the unlocking handle on one side thereof, and the unlocking handle is moved by pressing to adjust the position of the lock tongue 104 relative to the lock tooth 103 to complete unlocking or locking;

[0057] A circuit board is integrated inside the flange nut sleeve body 101, and a Hall sensor is integrated on the circuit board. Both the circuit board and the Hall sensor communicate with the software platform and / or app of the external control system to monitor the status of the lock structure in real time.

[0058] Specifically, this embodiment discloses a monitoring device suitable for monitoring the real-time status of pipelines and valves in a refinery; it mainly includes a lock structure 1 and an unlocking handle structure 2, and a control part for monitoring the status of the lock structure 1, wherein the control part of this embodiment is a circuit board and a Hall sensor integrated on the circuit board, and the unlocking and locking status of the lock structure 1 are monitored in real time through the Hall sensor, and the status signal is transmitted to the software platform or app of the control platform. The lock structure 1 of this embodiment is divided into a flange nut sleeve main body 101 and a flange nut sleeve matching body 102, wherein the flange nut sleeve matching body 102 has a locking tooth 103, which cooperates with the lock tongue 104 to complete the switching between the locked and unlocked states. The unlocking handle structure 2 of this embodiment is the main operating component for adjusting the relative position of the lock tongue 104 and the lock tooth 103. The unlocking handle of this embodiment is unlocked and locked by pressing, which is easy to operate.

[0059] Preferably, the locking teeth 103 of this embodiment are configured as a long strip structure that penetrates the flange nut sleeve body 101;

[0060] The lock tooth 103 and the lock tongue 104 have a first tooth portion on one side thereof;

[0061] The position where the locking tongue 104 cooperates with the first tooth portion of the locking tooth 103 has a second tooth portion, and the first tooth portion meshes with the second tooth portion.

[0062] Preferably, the lower end of the locking tongue 104 of this embodiment facing the flange nut sleeve body 101 is connected to a locking tongue spring rod 106, and the lower end of the locking tongue spring rod 106 is connected to a locking tongue spring 105;

[0063] The bolt spring 105 pushes the bolt spring rod 106 and the bolt 104 to move by the spring force.

[0064] The lock tongue 104 of this embodiment adjusts its position by moving the unlocking handle. When unlocking, when the unlocking handle moves in the opposite direction, the lock tongue 104 will be reset under the spring force of the lock tongue spring 105 below, so that the lock tongue 104 is engaged with the lock tooth 103 to achieve a locked state.

[0065] Preferably, the unlocking handle of this embodiment includes:

[0066] An unlocking handle operating portion 201 located outside; and

[0067] An unlocking handle extension portion 202 connected to the unlocking handle operating portion 201 and extending into the interior of the lock structure 1;

[0068] The position where the unlocking handle extension 202 cooperates with the lock tongue 104 is formed as a matching surface 20201, and a matching protrusion 20202 is protrudingly formed in the middle of the matching surface 20201;

[0069] When the lock tongue 104 abuts against the mating protrusion 20202, the lock tongue 104 contacts the lock tooth 103, and the lock structure 1 is in a locked state;

[0070] When the lock tongue 104 abuts against the mating surface 20201 , the lock tongue 104 is away from the lock tooth 103 , and the lock structure 1 is in an unlocked state.

[0071] The first locking structure of the device of this embodiment is the locking of the unlocking handle and the external structure through a padlock. Specifically, the unlocking handle operating part 201 of this embodiment is provided with a lock hole 203, and the lock hole 203 is used to install a padlock and lock it with the external structure through the padlock.

[0072] Since the unlocking handle of this embodiment is unlocked and locked by pressing, based on this principle, a handle locking track 206 is provided on the back of the unlocking handle extension 202 of this embodiment;

[0073] Secondly, a handle locking spring rod 204 is provided at the position where the flange nut sleeve body 101 of this embodiment cooperates with the unlocking handle extension portion 202;

[0074] When the unlocking handle is moved by pressing, the handle locking spring rod 204 moves along the handle locking track 206 .

[0075] Specifically, the handle locking track 206 of this embodiment includes:

[0076] Horizontal track 20601;

[0077] The inclined track 20602 is connected to the horizontal track 20601, and a bending area 20603 is formed between the inclined track 20602 and the horizontal track 20601. The handle locking spring rod 204 can move along the inclined track 20602 and enter the bending area 20603, and tighten the unlocking handle to maintain the position of the unlocking handle.

[0078] During actual operation, first release the padlock at the lock hole 203, then press the unlocking handle, and the unlocking handle moves inward. At this time, the lock tongue anti-retraction safety 207 is released, and the unlocking handle continues to be pressed. At this time, the lock tongue 104 is away from the lock tooth 103 and reaches the unlocked state of the lock structure 1, and the internal handle locking spring rod 204 enters the bending area 20603 on the rear side along the inclined track 20602, and stays in the bending area 20603 and pulls the unlocking handle. At this time, the unlocking operation of the lock structure 1 is completed, and the entire unlocking state will be uploaded to the external control platform or app through the control part of this embodiment.

[0079] Secondly, when the lock structure 1 needs to be locked, continue to press the unlocking handle. At this time, under the action of the inclined track 20602 on the other side of the bending area 20603, the handle locking spring rod 204 will re-enter the horizontal track 20601, and the constraint on the unlocking handle will be released, and the unlocking position will be popped out. The unlocking handle will be reset and the lock tongue 104 will be released, allowing the lock tongue 104 to engage with the lock tooth 103 again to complete the locking operation.

[0080] In order to assist the unlocking handle in resetting, a handle spring 205 is connected between the unlocking handle extension 202 and the flange nut sleeve body 101 of this embodiment.

[0081] Preferably, as an extended implementation method, the Hall sensor of this embodiment uses the AH473 Hall sensor. The AH473 of this embodiment is a micro-power, high-sensitivity, omnipolar Hall switch chip, designed and produced using CMOS technology. The chip device integrates a voltage regulator, a Hall voltage generator, a small signal amplifier, a chopper regulator, a Schmitt trigger and a CMOS output driver. The chip has the characteristics of good temperature stability, strong stress resistance, high sensitivity, etc., and the operating voltage is 2.2V~5.5V. TO92S plug-in package and SOT23-3L package are provided, and the packages are in compliance with RoHS environmental protection standards.

[0082] The monitoring equipment of this embodiment can transmit the operation process and status of the operation site in real time and transmit it to the control platform to assist the management personnel in overall control of the blind plate and valve. The monitoring equipment locks the nut of the flange (i.e., through the flange nut sleeve of this application) to prevent the blind plate between the flanges from being accidentally removed or misoperated, and can also lock the valve with a cable.

[0083] In the above technical solution, the utility model provides an intelligent energy isolation monitoring device, which has the following beneficial effects:

[0084] The monitoring equipment of the utility model uses a combination of software and hardware to manage the energy isolation operation process throughout its life cycle. It uses blind plate intelligent sensing tools and valve intelligent sensing tools to transmit the real-time status of blind plates and valves at the operation site, and cooperates with the operation process management of the software platform and app to solve the problem that the energy isolation operation cannot be controlled in a real-time integrated manner, improve the standardization of energy isolation operations, and reduce the probability of safety accidents caused by non-standard energy isolation operations.

[0085] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
