Detailed Description

The utility model provides a generator backup protection measurement and control device, refer to fig. 1 to fig. 2, including the main casing body, the main casing body outside is equipped with display screen 1 and control button 2, main casing body internally mounted has main control panel 5. It should be noted that, a user can perform control operation of the measurement and control device through the control key 2, and at the same time, can view data of the generator in real time through the display screen 1. It should be noted that, in this embodiment, the structure and the installation manner of the main housing of the measurement and control device and the main control board 5 are improved, and the control principle and the working principle of the measurement and control device are the prior art, which are not the main points of the present embodiment, and are not described herein again.

The main casing body comprises a bottom casing 3 and a cover plate 4 which are spliced with each other, the bottom casing 3 is provided with an accommodating cavity 31 for installing the main control board 5, the cover plate 4, the main control board 5 and the accommodating cavity 31 are all arranged in a rectangular shape, four corners at the bottom of the accommodating cavity 31 are respectively provided with a supporting table 32, four right-angle parts of the main control board 5 are erected on the surface of the supporting table 32, the surface of the supporting table 32 is also provided with an L-shaped clamping groove 321, the main casing body further comprises elastic limiting blocks 33 which are in one-to-one correspondence with the supporting table 32, each elastic limiting block 33 comprises a L-shaped clamping table 331 which is clamped with the L-shaped clamping groove 321, the main casing body further comprises a butting part 332 which is butted with the four right-angle parts of the main control board 5, the bottom of the accommodating cavity 31 is provided with a plurality of radiating holes 34 which are arranged in an array shape, sliding grooves 35 which are symmetrically arranged at the opening of the accommodating cavity 31 and used for installing the cover plate.

It should be noted that, this embodiment has improved traditional measurement and control device's casing mounting structure, has cancelled traditional lock screw structure, carries out sliding connection through the spout structure between apron 4 and the drain pan 3, and rethread elastic positioning element 41 and locating hole 36 further joint location realize the concatenation of drain pan 3 and apron 4, not only guarantee the stability of installation between the two, still make things convenient for installation and dismantlement between the two, convenient to use. Simultaneously, further improved the mounting means of main control board 5, through setting up a supporting bench 32, erect main control board 5 in drain pan 3, improved its area of contact with the air greatly, convenient heat dissipation, simultaneously, be equipped with the louvre 34 that corresponds with main control board 5 bottom drain pan 3, louvre 34 is ring array form and arranges for the inside air flow of drain pan 3 has further improved the radiating efficiency. Simultaneously, still increased elastic limiting block 33 and fixed and spacing the installation of main control board 5, when guaranteeing main control board 5 installation stability, when measuring and control device received external force striking, four straight angle portions of main control board 5 were restricted in elastic limiting block 33, can extrude elastic limiting block 33, cushioned main control board 5 promptly, prevented because the influence of external force, caused main control board 5 to damage, improved its life.

Specifically, during installation, the main control board 5 is firstly erected on the four supporting tables 32 of the accommodating cavity 31, so as to achieve the maximum contact area between the main control board 5 and air, then the four elastic limiting blocks 33 are respectively and correspondingly installed on the surfaces of the supporting tables 32 in sequence, namely L-type clamping tables 331 of the elastic limiting blocks 33 are respectively inserted into L-type clamping grooves 321, L-type clamping grooves 321 can limit the positions of the elastic limiting blocks 33 and prevent the elastic limiting blocks 33 from rotating, and secondly, after the elastic limiting blocks 33 are installed in place, the abutting parts 332 of the elastic limiting blocks are respectively abutted against two side surfaces and the upper surface of a straight corner part of the main control board 5, and then the supporting tables 32 are abutted against the lower surface of the main control board 5, so that the main control board 5 is stably installed in the accommodating cavity 31 and can provide a certain buffer for the main control board.

Further, after the main control board 5 is installed in place, the cover plate 4 and the bottom case 3 are spliced. Specifically, the cover plate 4 is inserted along the end of the sliding slot 35, and it should be noted that the outer side of the cover plate 4 is matched with the inner side of the sliding slot 35, so that the elastic positioning member 41 on the side of the cover plate 4 is squeezed by the inner side of the sliding slot 35 to contract in the process of sliding the cover plate 4 into the sliding slot 35, thereby ensuring that the cover plate 4 is smoothly inserted into the sliding slot 35. After the cover plate 4 is installed in place, the elastic positioning parts 41 respectively correspond to the positioning holes 36 on the inner side surfaces of the sliding grooves 35 one by one, at the moment, the elastic positioning parts 41 lose the extrusion of the inner side surfaces of the sliding grooves 35, extend into the positioning holes 36 under the action of self elastic restoring force and are clamped with the positioning holes 36 one by one, and therefore the stability of installation between the cover plate 4 and the bottom shell 3 is guaranteed. When the cover plate 4 and the bottom case 3 need to be separated, the cover plate 4 is pushed out along the sliding groove 35 by force, and in the pushing-out process, the elastic positioning piece 41 is squeezed by the side wall of the positioning hole 36 and compressed again, so that the cover plate 4 can smoothly slide out of the sliding groove 35. It should be noted that, during the process of sliding the cover plate 4 into or out of the sliding slot 35, the elastic positioning element 41 passes through the positioning hole 36 several times, and is compressed by the positioning hole 36 and the side wall of the sliding slot 35, so as to ensure that the cover plate 4 slides into or out of the sliding slot 35 smoothly.

Further, the elastic positioning member 41 is configured as a ball plunger. The bulb plunger is the standard component among the prior art, and is with low costs, long service life, and the tip of bulb plunger and 36 joints of locating hole is globular, at apron 4 installation and dismantlement in-process, can greatly reduced bulb plunger and 35 medial surfaces of spout and the frictional force between locating hole 36 to make things convenient for the installation and the dismantlement of apron 4.

Furthermore, a dust screen (not shown in the figure) is added in the heat dissipation hole 34, and the dust screen can be arranged in the heat dissipation hole 34 through an after-forming manner in the prior art, so that large particle dust outside can be effectively prevented from entering the accommodating cavity 31 from the heat dissipation hole 34 and affecting the normal use of the accommodating cavity.

Further, the bottom case 3 and the cover plate 4 are respectively provided as an aluminum alloy integrally formed structure. The aluminum alloy material has light weight and good heat conduction effect, can further accelerate heat dissipation and reduce the overall mass of the liquid crystal display screen 1.

The above is only the preferred embodiment of the present invention, and not the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings or the direct or indirect application in other related technical fields are included in the patent protection scope of the present invention.
