Description

Novel low-pressure drawer with temperature measuring function Technical Field The utility model relates to the technical field of low-pressure drawers, in particular to a novel low-pressure drawer with a temperature measuring function. Background In the existing low-voltage drawer type switch cabinet structure, a movable plug-in unit of a main plug-in unit is generally connected to the rear part of a drawer body in a horizontal direction in a horizontal arrangement mode, and is disclosed in Chinese patent publication No. CN209313281U, wherein the three-phase movable plug-in unit is installed in an integral shell, and then is fixedly connected to the rear part of the drawer body through a bolt through the shell. In the above patent scheme, because the three-phase moves the plug-in components integration in an integral shell, when one of them looks moves the plug-in components and breaks down and need maintenance or change, need wholly dismantle the drawer body with the shell, the operation degree of difficulty is great, inconvenient single-phase moves the plug and installs and removes alone. And the temperature sensor is arranged in the shell, so that the temperature sensor is inconvenient to overhaul and replace, an alarm mechanism is provided through a control circuit board arranged in the drawer body, and the temperature of the movable plug-in unit of the low-voltage drawer of the whole electric room is not beneficial to a user to monitor remotely. Disclosure of utility model The utility model aims to solve the technical problem of providing a novel low-pressure drawer with a temperature measuring function, which is convenient for independent assembly and disassembly of a single-phase movable plug-in unit and a temperature sensor thereof and is convenient for remote monitoring of users by improving the structure of the rear part of a drawer body and the structure of each phase movable plug-in unit. In order to solve the technical problems, the utility model adopts the following technical scheme: A novel low-pressure drawer with a temperature measurement function comprises a drawer body, wherein three mounting holes distributed in a straight array along an inclined direction are arranged at the rear part of the drawer body; The single-phase movable plug comprises a shell and a movable plug body connected in the shell, wherein the movable plug body comprises a contact mechanism and a connecting sheet, the contact mechanism is exposed out of the rear part of the shell, the connecting sheet is exposed out of the front part of the shell, the connecting sheet is connected with a copper bar through a binding post, and the copper bar is detachably connected with a wireless temperature sensing device; The wireless temperature sensing device comprises a first clamping arm and a second clamping arm which are mutually pivoted; when in an assembled state, the first clamping arm and the second clamping arm are respectively clamped at two sides of the copper bar; The wireless temperature sensor is embedded in the middle of the first clamping arm and is integrated with a temperature sensing element, an amplifying circuit module, an analog-to-digital converter, a microcontroller, a wireless communication module and a power module which are electrically connected with each other, and when the wireless temperature sensor is in an assembled state, the temperature sensing element is contacted with one surface of the copper bar.
