Description

Technical Field

[0001] The invention relates to the technical field of control cabinets, and more particularly to an electrical control cabinet for facilitating installation of electrical components. Background Art

[0002] The control cabinet is a combination of switchgear, measuring instruments, protective electrical appliances and auxiliary equipment assembled in a closed or semi-enclosed metal cabinet or on a screen according to the requirements of electrical wiring. Its layout should meet the requirements of normal operation of the power system, be easy to repair, and not endanger the safety of people and surrounding equipment. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. In case of failure or abnormal operation, the circuit can be cut off or alarmed with the help of protective electrical appliances. Various parameters in operation can be displayed by measuring instruments, and some electrical parameters can be adjusted, and prompts or signals can be issued for deviations from normal working conditions. There are many types of control cabinets, including electrical control cabinets, frequency conversion control cabinets, low-voltage control cabinets, high-voltage control cabinets, water pump control cabinets, power control cabinets, explosion-proof control cabinets, elevator control cabinets, PLC control cabinets, fire control cabinets, brick machine control cabinets, etc.

[0003] When installing electrical components of an existing control cabinet, workers often first fix the electrical installation board of the control cabinet on the rear wall of the cabinet, and then install multiple electrical components on the electrical installation board. However, due to the small internal space of the distribution cabinet, it is not convenient to install the electrical components. In addition, some workers install all the electrical components on the electrical installation board first, and then move the electrical installation board with the electrical components installed into the cabinet as a whole and fix the installation board inside the cabinet. However, the overall weight of the installation board with the electrical components installed is generally heavy, which is not convenient to move, and it is time-consuming and laborious to move. Moreover, due to the small internal space of the cabinet, it is also not convenient to install the electrical installation board. In addition, the existing electrical control cabinets placed outdoors do not have a snow sweeping function, and the snow accumulated on the electrical control cabinet is not promptly and effectively handled. As a result, when the snow melts, the snow water easily enters the electrical control cabinet, causing damage to the electrical components in the electrical control cabinet. Summary of the invention

[0004] In view of this, the present invention provides an electrical control cabinet that is easy to install electrical components, so as to solve the problem that the electrical components inside the existing electrical control cabinet are inconvenient to install and the snow accumulated on the cabinet body melts into snow water and enters the cabinet body, causing damage to the electrical components inside the cabinet.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] An electrical control cabinet for facilitating installation of electrical components, comprising:

[0007] A cabinet body, wherein a cabinet door is provided on one side of the cabinet body, long strip guide grooves are provided on the tops of two opposite inner side walls of the cabinet body, and a snap-in hole is provided on the inner bottom surface of the cabinet body;

[0008] An electrical installation plate, wherein the tops of two opposite side walls of the electrical installation plate are hinged with sliding rods, and the two sliding rods are respectively slidably connected in the two long strip guide grooves;

[0009] A support rod, the top of the support rod is hingedly connected to the bottom of the electrical installation board, the lower end of the support rod is provided with a receiving hole, a spring is arranged inside the receiving hole, one end of the spring is fixed to the bottom of the receiving hole, and the other end is fixedly connected to one end of the plug-in rod extending into the receiving hole, and the other end of the plug-in rod is supported on the ground or plugged into the card-in hole;

[0010] When the electrical installation board is pulled out from the interior of the cabinet and arranged at an angle, the sliding rod abuts against the lower groove wall of the long guide groove, and the other end of the plug-in rod is supported on the ground; when the electrical installation board is pushed into the interior of the cabinet, the sliding rod abuts against the upper groove wall of the long guide groove, and the other end of the plug-in rod is inserted into the insertion hole.

[0011] It can be known from the above technical solutions that, compared with the prior art, the present invention discloses an electrical control cabinet that is convenient for installing electrical components. The electrical installation board is directly pulled out from the cabinet and arranged obliquely facing the installer, so that the installer can install the electrical components at a better installation angle outside the cabinet, avoiding the problem of inconvenience caused by installing the electrical components inside the narrow cabinet. After the electrical components are installed, the electrical installation board is directly pushed into the cabinet, which is very convenient to operate. In addition, the electrical installation board and the cabinet are installed by top sliding and bottom clamping, so that the electrical installation board and the cabinet are an integrated connection structure, rather than a separate component, so as to avoid the time-consuming and labor-intensive problem of moving the electrical installation board with electrical components installed into the cabinet as a whole and fixing the installation board inside the cabinet.

[0012] Therefore, the electrical installation board of the control cabinet is installed in the cabinet body in a pull-out manner, which makes it convenient for the installer to directly install the electrical components on the electrical installation board outside the cabinet body, and it is also more labor-saving to push the electrical installation board with the electrical components installed into the cabinet body, so that the control cabinet has the effects of convenient installation of electrical components, time-saving and labor-saving pulling out and pushing in of the electrical installation board, and simple operation.

[0013] Furthermore, a gas spring is fixed on the rear inner wall of the cabinet, and the telescopic end of the gas spring is hingedly connected to the rear side wall of the electrical installation board.

[0014] The beneficial effects of adopting the above technical solution are: when the electrical installation board is pulled out from the cabinet, the gas spring can exert an outward thrust on the electrical installation board, so that the electrical installation board can be pulled out more labor-saving; and the gas spring can provide auxiliary support for the electrical installation to ensure that the electrical installation board is in an inclined state facing the installer.

[0015] Furthermore, a handle is provided on the front side of the electrical installation board.

[0016] The beneficial effect of adopting the above technical solution is that the electrical installation board can be easily pulled out from the cabinet by the handle.

[0017] Furthermore, a top cover snow shaking mechanism for shielding the cabinet is fixed on the top of the cabinet.

[0018] The beneficial effect of adopting the above technical solution is that the cabinet can be shielded from rain and snow, reducing the risk of rain and snow entering the cabinet and causing damage to electrical components.

[0019] Furthermore, the top cover snow shaking mechanism includes:

[0020] A support column, the lower end of which is fixedly connected to the top of the cabinet;

[0021] Two electric push rods, which are respectively fixedly mounted on the two side walls of the support column;

[0022] The first snow-shaking top cover plate and the second snow-shaking top cover plate are hingedly connected by hinges, and the bottom end surfaces of the first snow-shaking top cover plate and the second snow-shaking top cover plate are respectively hingedly connected to the telescopic ends of the two electric push rods, so as to keep the first snow-shaking top cover plate and the second snow-shaking top cover plate in a herringbone or horizontal state, or to make the first snow-shaking top cover plate and the second snow-shaking top cover plate shake up and down to perform snow removal operations.

[0023] The beneficial effects produced by the above-mentioned technical scheme are as follows: in the initial state, the first snow-shaking top cover plate and the second snow-shaking top cover plate are in a herringbone state, which is convenient for the snow to slide down automatically; when there is still snow on the first snow-shaking top cover plate and the second snow-shaking top cover plate, the two electric push rods are repeatedly extended and retracted, driving the first snow-shaking top cover plate and the second snow-shaking top cover plate to continuously shake back and forth up and down, so that the accumulated snow can be shaken off, thereby realizing the automatic snow removal function; in addition, the first snow-shaking top cover plate and the second snow-shaking top cover plate can also be placed in a horizontal state through the two electric push rods, so that maintenance personnel can place maintenance tools directly on the first snow-shaking top cover plate and the second snow-shaking top cover plate, thereby achieving the effect that the top cover can be used to place tools, avoiding the problem of tools being placed on the ground at random due to no place to put them, resulting in repeated bending over to pick up tools or the risk of being tripped by tools.

[0024] Furthermore, one side end of the first snow-shaking top cover is hingedly connected to the inner bottom surface of the second snow-shaking top cover near its one side end, and one side end of the second snow-shaking top cover can be located obliquely upward above the first snow-shaking top cover.

[0025] The beneficial effect of adopting the above-mentioned technical scheme is: because the first snow-shaking top cover plate and the second snow-shaking top cover plate are hingedly connected, there is a gap between the two, and the gap is located below the second snow-shaking top cover, that is, one side end of the second snow-shaking top cover is arranged obliquely upward, which can block snow or rainwater, and prevent snow or rainwater from entering the gap and falling to the top of the cabinet, entering the cabinet and damaging electrical components.

[0026] Furthermore, an elastic sealing belt is fixed between one side end of the second snow-shaking top cover plate and the first snow-shaking top cover plate.

[0027] The beneficial effect of adopting the above-mentioned technical scheme is: because the first snow-shaking top cover plate and the second snow-shaking top cover plate are connected by a hinge, there is a gap between the two, and there is a problem that snow or rainwater falls through the gap to the top of the cabinet and enters the interior of the cabinet. Therefore, the elastic sealing belt can prevent snow or rainwater from entering the gap.

[0028] Furthermore, electric heating wires are provided inside the first snow-shaking top cover plate and the second snow-shaking top cover plate.

[0029] The beneficial effect of adopting the above-mentioned technical scheme is: when the snow on the upper surfaces of the first snow-shaking top cover plate and the second snow-shaking top cover plate cannot be shaken off or is frozen, the upper surfaces of the first snow-shaking top cover plate and the second snow-shaking top cover plate are heated by electric heating wires to melt the snow or ice, thereby achieving the purpose of snow and ice removal.
