[0042] Example 2

[0043] As Figure 2 、 3 and 5, the embodiment provides a power system safety monitoring and alarming device, which is different from example 1 in that the connecting mechanism 5 comprises a pushing assembly, the pushing assembly comprises a push rod 508 and a second sliding block 502, the push rod 508 is fixedly connected with the second sliding block 502, and the push rod 508 and the second sliding block 502 are slidingly connected with the side of the mounting plate 2 away from the shell 1; the connecting mechanism 5 comprises a reset assembly, the reset assembly comprises a connecting rod 503, a connecting column 504 and a tension spring 505, the rear end of the connecting rod 503 is rotationally connected with the second sliding block 502, the opposite end of the connecting rod 503 is fixedly connected with the tension spring 505, and the front ends of the connecting column 504 are fixedly connected with the connecting rod 503.

[0044] In the specific operation process, when the centralized box 3 is installed, first push the push rod 508 to the inside along the horizontal groove, the push rod 508 drives the second sliding block 502 to move to the inside, because the connecting column 504 on the connecting rod 503 is in sliding connection with the mounting plate 2, when the second sliding block 502 moves, it will drive the connecting rod 503 to move the first sliding block 501 to the outside, when the first sliding block 501 moves to the outside, it will drive the fixed plate 506 to move to the outside along the horizontal groove, then place the centralized box 3 on the mounting plate 2, loosen the push rod 508, due to the reset of the pull spring 505, it will push the second sliding block 502 to move to the outside, so that the first sliding block 501 moves to the inside, then the fixed plate 506 also moves to the inside, and the limiting groove 507 is arranged on the fixed plate 506, when the two fixed plates 506 move to the inside, the limiting groove 507 will be clamped with the limiting block 509 on both sides of the centralized box 3, so as to complete the installation of the centralized box 3, and reduce the time-consuming and cumbersome process of installation.

[0045] Embodiment 3

[0046] As shown in Figure 2 , the embodiment provides a power system safety monitoring alarm device, which is different from the embodiment 2 in that the centralized box comprises an induction mechanism and an alarm mechanism; the induction mechanism uses a Hall current sensor; the alarm mechanism comprises a buzzer and a flashing light; the front end top of the centralized box is connected with the buzzer, and the top sides of the centralized box are connected with the flashing lights; the centralized box is provided with limiting blocks; the limiting blocks are matched with limiting grooves; and the shell is provided with a transparent panel.

[0047] As an optional solution, the transparent panel 7 is a member made of one of acrylic, polycarbonate or polyethylene terephthalate, which can be replaced by other transparent material members according to actual conditions.

[0048] As an optional solution, the centralized box is provided with an electronic chip, and the electronic chip is electrically connected with the induction mechanism and the alarm mechanism.

[0049] In the specific operation process, the inside of the centralized box 3 is designed with a card slot structure matched with the electronic chip, and the electronic chip is directly embedded in the card slot to realize fixation. When the induction mechanism 301 detects the safety of the power system in the laboratory, the induction mechanism 301 uses a Hall current sensor to detect the current size in the circuit. When the current exceeds the preset safety threshold, it indicates that the power system in the laboratory is dangerous. The induction mechanism 301 outputs an electrical signal to the electronic chip, starts the alarm mechanism 302, and starts the buzzer 3021 and the flashing light 3022. When the current is lower than or equal to the preset safety threshold, it indicates that the power system in the laboratory is normal. The induction mechanism 301 does not output an electrical signal, the alarm mechanism 302 is closed, and the buzzer 3021 and the flashing light 3022 do not work. In order to make the flashing light 3022 more easily observed when alarming, the front panel of the box body is replaced with a transparent material. When the flashing light 3022 flashes, personnel can directly observe the light of the flashing light 3022 through the observation window even outside the device, so that the alarm condition can be known more conveniently and timely. In order to realize remote monitoring and data sharing, the data collected by the laboratory power safety monitoring chip is usually connected to external equipment through a wireless communication circuit.

[0050] Embodiment 4

[0051] As shown in Figure 1 , the embodiment provides a power system safety monitoring and alarming device. The difference from embodiment 3 is that the operation panel 4 includes a touch screen 401, an indicator light 402, and a knob 403.

[0052] As an optional solution, the knob 403 is a three-position knob.

[0053] In the specific operation process, the working state of the power system is controlled through the knob 403. The three-position knob is used to select the required three working states. The three-position knob is connected to three different circuits. The three functions of “running”, “stopping”, and “repairing” are realized by controlling the three buttons with the three-position knob. Based on the switching control of the button connection circuit by the different position states of the three-position knob, when the knob 403 is rotated to the left, it is in the “running” state, the running control circuit of the system starts to work, the “running” indicator light is on, and the power system starts to run. When the knob 403 is rotated to the middle, it is in the “stopping” state, the current path is cut off, the running control circuit of the system stops working, only the “stopping” indicator light is on, and the power system stops running. When the knob 403 is rotated to the right, it is in the “repairing” state. When it is in the “repairing” state, the “repairing” indicator light is on, and the safe repairing mode is entered. At the same time, the touch screen 401 can realize man-machine interaction. The real-time parameter state of the device will be displayed on the touch screen 401, and the user experience is enhanced.

[0054] For the above embodiments, it needs to be explained that the Hall current sensor, the electronic chip, the three-position knob, and the touch screen 401 are all prior art, and their principles and connection modes with the power supply are clear and easy to implement for those skilled in the art, so they will not be described in detail here.

[0055] The embodiments of the utility model are explained in detail above in combination with the drawings, but the utility model is not limited to the above embodiments, and various changes can be made within the knowledge range possessed by those skilled in the art without departing from the purpose of the utility model.
