DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 3 The utility model provides a technical solution: a power plant safety monitoring device, including a front panel cover 1, a rear shell 2 and an insulating pad 8. The front side of the front panel cover 1 is an operation panel, and the inner cavity of the rear shell 2 is a space for accommodating instrument components. After the mouth of the front panel cover 1 and the rear shell 2 are connected, the insulating pad 8 is located between the contact surface of the front panel cover 1 and the rear shell 2. The function of the insulating pad 8 is to prevent the current on the outer shell 2 from flowing into the front panel cover 1, thereby preventing electric shock during operation. The technical solution is to improve the defect of the prior art that it is inconvenient to repair the components in the rear shell 2 after the front panel cover 1 is opened. Other disclosed or described structures all adopt the structures in the prior art.

[0024] In the technical scheme, the top of the rear shell 2 is connected to the guide shaft 3 for sliding forward and backward. In the specific implementation, it is preferred that the top of the rear shell 2 is welded with a guide sleeve 22 close to the front end and sleeved on the guide shaft 3. The front end of the guide shaft 3 is rotatably connected to the back of the front panel cover 1. When the guide shaft 3 slides outward and drives the front panel cover 1 to separate from the rear shell 2 and rotates, it can further increase the space at the mouth of the rear shell 2. The rear end of the guide shaft 3 is fixedly connected to a right-angle suspension rod 4, and the top of the cross bar 41 on the right-angle suspension rod 4 is fixedly connected to a positioning plate 5. The top of the positioning plate 5 is provided with a mounting seat 6. The mounting seat 6 and the positioning plate 5 can be connected by welding. The function of the mounting seat 6 is to connect with the components, which can be specifically connected by screw connection, welding connection or clamping connection. The specific connection method is selected as needed. Therefore, when the guide shaft 3 slides outward, the positioning plate 5 will drive the components on it to the mouth of the rear shell 2, increase the large space around the components, and improve the convenience of the operator to repair the instrument components.

[0025] Furthermore, a connection sleeve 11 is welded on the back of the front panel cover 1, and an insulating rubber sleeve 111 is nested in the connection sleeve 11. The function of the insulating rubber sleeve 111 is to ensure the insulation of the front panel cover 1 and the safety of the operator when operating the front panel cover 1. The front end of the guide shaft 3 is sleeved in the insulating rubber sleeve 111 and is a damping type rotation fit. Specifically, the insulating rubber sleeve 111 provides rotation resistance to the rotation fit of the connection sleeve 11 and the guide shaft 3. This arrangement facilitates the front panel cover 1 to stop at any position after rotation.

[0026] In this embodiment, a closed-loop slot 21 is provided on the front end face of the rear shell 2, and the closed-loop slot 21 is a rectangular frame-type recessed groove structure. A closed-loop frame 12 is welded on the back of the front panel cover 1 and is gap-fitted with the closed-loop slot 21. The closed-loop frame 12 is also a rectangular frame structure. A closed-loop groove sleeve 81 is provided on the insulating pad 8 and is nested in the closed-loop slot 21. The closed-loop frame 12 and the closed-loop groove sleeve 81 are interference fit. After the closed-loop frame 12 is inserted into the closed-loop groove sleeve 81, the rear shell 2 and the front panel cover 1 are in a tightly plugged state, and the function of isolation and protection against electric shock is realized at the same time.

[0027] Furthermore, an elastic telescopic support rod 7 is hingedly connected to the bottom of the rear shell 2, and the action end of the elastic telescopic support rod 7 is hingedly connected to the bottom of the right-angle suspension rod 4. The elastic telescopic support rod 7 adopts a common two-section telescopic structure with a built-in support spring. The function of the elastic telescopic support rod 7 is to apply an axial elastic thrust to the guide shaft 3 through the right-angle suspension rod 4. The direction of this elastic thrust is determined by the position of the elastic telescopic support rod 7. When the front panel cover 1 closes the rear shell 2, the elastic telescopic support rod 7 will tilt toward the rear of the rear shell 2. At this time, the elastic telescopic support rod 7 will apply elastic pressure to the guide shaft 3 to push into the rear shell 2, which has the function of effectively preventing the front panel cover 1 and the rear shell 2 from separating. When the front panel cover 1 is fully opened, the elastic telescopic support rod 7 tilts toward the mouth of the rear shell 2, so that the front panel cover 1 is in a stable open state.

[0028] In this embodiment, a rack 42 located below the guide shaft 3 is welded to the outer wall of the right-angle suspension rod 4. The rack 42 is parallel to the guide shaft 3. A transmission shaft 9 located between the rack 42 and the guide shaft 3 is rotatably connected in the rear shell 2. A gear 91 meshing with the rack 42 is solidly sleeved on the transmission shaft 9. When the transmission shaft 9 is controlled to rotate, the gear 91 can be driven to rotate, thereby driving the guide shaft 3 to move axially.

[0029] Furthermore, both ends of the transmission shaft 9 pass through the two side walls of the rear shell 2, and the two ends of the transmission shaft 9 are fixedly connected with knobs 92, which are operating components for manually controlling the rotation of the transmission shaft 9. Therefore, the opening and closing of the front panel cover 1 can be controlled by controlling the forward and reverse rotation of the knob 92.

[0030] The outer sleeve of the knob 92 is provided with an insulating cover 921 to improve the safety of manual hand-held operation.

[0031] Working principle: During use, when it is necessary to inspect the components in the rear shell 2, manually hold the knob 92 and turn it. The transmission shaft 9 rotates through the gear 91 to drive the rack 42. At this time, the guide shaft 3 slides outward, and the closed-loop frame 12 begins to disengage from the closed-loop groove sleeve 81. At the same time, due to the traction of the right-angle suspension rod 4, the elastic telescopic support rod 7 begins to compress. When the elastic telescopic support rod 7 is compressed to the limit position and tilted toward the rear square of the rear shell, the elastic telescopic support rod 7 extends to assist in pushing the guide shaft 3 outward. During this process, the components on the positioning plate 5 move to the mouth of the rear shell 2. At this time, the operator can inspect the components more intuitively.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
