[0022] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without deviating from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

[0023] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment.

[0024] EMBODIMENT

[0025] Referring to Figures 1-4 For the embodiment of the utility model, the embodiment provides high voltage switchgear environment temperature and humidity state monitoring device, can realize without using tool or complex operation step, temperature and humidity monitoring appearance (100) is disassembled fast simultaneously, in temperature and humidity monitoring appearance (100) installation is completed, ensure the position of temperature and humidity monitoring appearance 100 can accurate control's effect.

[0026] Temperature and humidity monitoring appearance 100, including dampproof box 101, the control panel 102 of adaptive installation in the outer surface of dampproof box 101 and the digital display screen 103 of fixed installation in the inner surface of control panel 102;

[0027] It should be noted that the dampproof box 101 is used to protect the internal electronic components, prevent moisture and dust from entering, and ensure that the temperature and humidity monitoring appearance 100 works normally in harsh environment. The control panel 102 is used to provide a user interface for easy operation and setting. The digital display screen 103 is used to display real-time temperature and humidity data for easy checking by maintenance personnel.

[0028] The deployment mechanism 200 includes a mounting bracket 201 disposed on the outside of the temperature and humidity monitoring appearance 100, a hand wheel 202 located on the outside of the mounting bracket 201, a roller column 203 fixedly connected to the through end of the hand wheel 202, a plurality of variable distance grooves 204 respectively formed on the two side surfaces of the roller column 203, a sliding block 205 disposed inside the variable distance groove 204, a connecting block 206 fixedly installed on the outer end surface of the sliding block 205, a limiting rod 207 fixedly connected to the inner side wall of the connecting block 206 and cooperated with the connecting block 206, and a disassembly assembly 208 cooperated with the gravity of the temperature and humidity monitoring appearance 100 for its own fixation.

[0029] It should be noted that the mounting bracket 201 is the support structure of the entire monitoring device. By rotating the hand wheel 202, the roller column 203 and the variable distance groove 204 can be rotated. The shape of the variable distance groove 204 allows the sliding block 205 to move along the limiting rod 207 at equal distances when the roller column 203 rotates, thereby achieving flexible adjustment of the position of the temperature and humidity monitoring appearance 100.

[0030] Specifically, a bearing sleeve cooperated with rotation is installed at the connection between the hand wheel 202 and the mounting bracket 201. The outer end surface of the connecting block 206 is fixedly installed on the inner side wall of the mounting bracket 201 through the bearing. The inner wall of the variable distance groove 204 is in sliding contact with the outer surface of the sliding block 205. The connecting block 206 is slidingly sleeved on the outer surface of the limiting rod 207.

[0031] Further, the disassembling and assembling component 208 comprises a special-shaped box 208a fixedly connected to the outer surface of the connecting block 206, a gear 208b fixedly installed on the inner wall of the special-shaped box 208a through a bearing, a straight rack 208c engaged with the outer surface of the gear 208b, and a bearing seat 208d fixedly connected to the penetrating end of the straight rack 208c and matched with the temperature and humidity monitor 100.

[0032] More should be explained that the temperature and humidity monitor 100 is placed above the bearing seat 208d, so that the temperature and humidity monitor 100 drives the bearing seat 208d and the straight rack 208c to move vertically and oppositely, and the straight rack 208c drives the gear 208b to rotate.

[0033] Preferably, the disassembling and assembling component 208 further comprises two inclined racks 208e respectively engaged with the two side surfaces of the gear 208b, and a clamping arm 208f fixedly connected to the penetrating end of the inclined rack 208e and matched with the temperature and humidity monitor 100.

[0034] Among them, the rotation of the straight rack 208c drives the two inclined racks 208e and the clamping arm 208f to move oppositely, so that the clamping arm 208f clamps and fixes the temperature and humidity monitor 100.

[0035] It should be explained that the disassembling and assembling component 208 further comprises a positioning block 208g fixedly connected to the inner surface of the special-shaped box 208a and matched with the straight rack 208c, a spring 208h fixedly installed on the top of the positioning block 208g, and two limiting columns 208i respectively fixedly connected to the inner surfaces of the two sides of the special-shaped box 208a and matched with the inclined rack 208e.

[0036] Further, the outer surfaces of the bearing seat 208d and the inclined rack 208e are in sliding contact with the inner surface of the special-shaped box 208a, the positioning block 208g is located on the inner side of the straight rack 208c, and the inner surface of the straight rack 208c is in sliding contact with the outer surface of the positioning block 208g.

[0037] Specifically, the limiting column 208i is located on the inner side of the inclined rack 208e, and the inner surface of the inclined rack 208e is in sliding contact with the outer surface of the limiting column 208i.

[0038] In use, the temperature and humidity monitor 100 is placed above the bearing seat 208d, so that the temperature and humidity monitor 100 drives the bearing seat 208d and the straight rack 208c to move vertically and oppositely, and the straight rack 208c drives the gear 208b to rotate, and then the rotation of the straight rack 208c drives the two inclined racks 208e and the clamping arm 208f to move oppositely, so that the clamping arm 208f clamps and fixes the temperature and humidity monitor 100.

[0039] When the position of the temperature and humidity monitor 100 is adjusted: rotating the hand wheel 202 can drive the roller column 203 and the variable distance groove 204 to rotate, the shape of the variable distance groove 204 enables the sliding block 205 to drive the connecting block 206 to move at equal distances along the limiting rod 207 when the roller column 203 rotates, thereby achieving the effect of flexible adjustment of the position of the temperature and humidity monitor 100.

[0040] When the temperature and humidity monitor 100 needs to be disassembled: the bearing seat 208d is gently pushed upward by hand, so that the straight rack 208c moves upward, the upward movement of the straight rack 208c drives the gear 208b to rotate, the rotation of the gear 208b drives the bevel gear 208e to move outward, thereby releasing the temperature and humidity monitor 100 from the clamping arm 208f, and after the clamping arm 208f is completely released, the temperature and humidity monitor 100 is gently grabbed with both hands and an upward force is applied, and the bearing seat 208d is manually lifted vertically upward.

[0041] In summary, through the cooperation between the components in the deployment mechanism 200, the temperature and humidity monitor 100 can be quickly disassembled without the use of tools or complex operation steps, and after the temperature and humidity monitor 100 is installed, the position of the temperature and humidity monitor 100 can be accurately controlled, thereby achieving the effect of greatly improving the maintenance and repair efficiency while avoiding the monitoring blind area caused by traditional fixed installation.
