[0002] With the rapid development of electrical technology, the use of electrical control cabinets has become more and more widespread. Electrical control cabinets are assembled in closed or semi-closed metal cabinets with switchgear, measuring instruments, protective electrical appliances and auxiliary equipment according to electrical wiring requirements. Their layout should meet the requirements for normal operation of the power system, facilitate maintenance, and not endanger the safety of people and surrounding equipment.

[0003] Referring to the Chinese patent, application number: "202122434339.0" for "An electrical control cabinet for electrical engineering automation", this patent solves the problem that the existing electrical control cabinet is prone to overheating due to long-term operation, affecting the normal operation of the control cabinet.

[0028] The present invention provides three technical solutions, including the following embodiments:

[0029] Example 1

[0030] See also Figure 1-Figure 5 An electrical control cabinet for electrical engineering automation includes a cabinet body 1, the cabinet body 1 is an electrical control cabinet, a horizontal plate 2 is fixed inside the cabinet body 1, and a fixed wire arrangement mechanism 3 for arranging and fixing a wire harness is arranged on the top of the horizontal plate 2;

[0031] The wire arrangement mechanism 3 includes a bracket 31 fixed on the top of the horizontal plate 2, a pentagonal sleeve 32 is fixed on one side of the bracket 31, five struts 33 are slidably connected to the inner surface of the pentagonal sleeve 32, a sleeve is provided on the pentagonal sleeve 32, the struts 33 slide inside the sleeve, arc plates 34 are fixed on the ends of the five struts 33 away from each other, a plurality of connecting rods 35 are fixed on the inner sides of the five arc plates 34, a wire clamp 36 is fixed on one end of the plurality of connecting rods 35, the wire clamp 36 is made of elastic plastic material, which can be deformed and expanded to clamp the wire harness, a driving component 37 is provided on the pentagonal sleeve 32 to drive the five struts 33 to expand and retract, and a gathering component 38 is provided on one side of the bracket 31 to gather the wire harness.

[0032] By setting up the wire arrangement mechanism 3, the wire clamp 36 is used to clamp the wire harness in the cabinet 1, and then the motor 375 is started, so that the support rod 33 drives the arc plate 34 to retract inward, so that the wire harness is gathered and arranged in a circular array in a regular manner.

[0036] Example 2

[0037] Based on Example 1, see Figure 3 and Figure 6 As shown, the gathering component 38 includes a fixed plate 3811 fixed on the bracket 31, and the top of the fixed plate 381 is rotatably connected to the bidirectional screw rod 381. When the bidirectional screw rod 381 rotates, it can drive the two clamping plates 383 to move towards or away from each other. The top of the horizontal plate 2 is fixed with a vertical rod 382, ​​and two clamping plates 383 are arranged on the top of the horizontal plate 2. The opposite sides of the two clamping plates 383 are provided with a slot for clamping the wiring harness. The top ends of the bidirectional screw rod 381 and the vertical rod 382 both penetrate the two clamping plates 383 and extend to the outside of the clamping plates 383. The outer surface of the bidirectional screw rod 381 is threadedly connected to the inner surface of the two clamping plates 383, and the outer surface of the vertical rod 382 is slidably connected to the inner surface of the two clamping plates 383.

[0039] By setting the gathering component 38, the wire harness is further gathered and gathered by using two wire clamping plates 383, so that the wire harness is further gathered together, and the arrangement of the wire harness is more regular and clear. At the same time, the gathering also increases the space of the cabinet 1, making the cabinet tidy and convenient for maintenance operations.

[0040] Example 3

[0041] Based on Example 2, see Figure 3 and Figure 7 As shown, a rapid cooling component 4 for cooling the gathered wire harness is arranged between the two clamping plates 383 and the top of the cabinet 1. The rapid cooling component 4 includes a refrigeration box 41 fixed on the top of the cabinet 1. The interior of the refrigeration box 41 is filled with refrigerant. The interior of the refrigeration box 41 is provided with a refrigerator for cooling the refrigerant. The refrigerator is a prior art, controlled by an external switch, and electrically connected to an external power supply. The refrigerator uses a specific refrigerant to absorb the heat of the external refrigerant through its internal working cycle. Inside the refrigerator, the refrigerant undergoes a series of steps such as compression, condensation, expansion, and evaporation, and continuously changes from a gaseous state to a liquid state and then back to a gaseous state. In this process, the refrigerant absorbs the heat of the external refrigerant liquid when evaporating in the evaporator, thereby reducing its temperature. Subsequently, the refrigerant gas that has absorbed the heat is compressed and condensed again, releasing the heat to the external environment. Through such a continuously circulating working mode, the refrigerator can effectively reduce the temperature of the external refrigerant to meet various cooling needs. One side of the refrigeration box 41 is connected to a liquid inlet hose 42, and the liquid inlet hose 42 injects the refrigerant into the liquid storage chamber 3810. The other side of the refrigeration box 41 is connected to a liquid outlet hose 43. The other side of the refrigeration box 41 is installed with a liquid pump 44. The liquid pump 44 is controlled by an external switch and is electrically connected to an external power supply. The liquid outlet hose 43 is connected to the liquid inlet and liquid outlet of the liquid pump 44. When the liquid pump 44 is started, the refrigerant in the liquid storage chamber 3810 is extracted through the liquid outlet hose 43, and then circulating flow refrigeration is performed.

[0042] The bottom ends of the liquid inlet hose 42 and the liquid outlet hose 43 are connected to the lower clamp plate 383, and the liquid inlet hose 42 and the liquid outlet hose 43 are connected to branch hoses 45. The two branch hoses 45 are connected to the upper clamp plate 383. The liquid inlet hose 42, the liquid outlet hose 43 and the branch hoses 45 are all made of soft rubber tubes and can be stretched and deformed.

[0043] By setting the rapid cooling component 4, the wire harness can be quickly cooled down by the circulating refrigerant in time after being gathered, so as to avoid the wire harness emitting a large amount of heat in the cabinet 1, thereby reducing the temperature in the cabinet. The lower temperature environment is conducive to the normal operation of the equipment in the cabinet.

[0044] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0045] During operation, the wiring harness in the cabinet 1 is inserted into the wiring clamp 36, and the motor 375 is started, so that the motor 375 drives the gear 2 374 and the gear 1 372 to rotate, and further the arc groove 373 on the gear 1 372 rotates to drive the connecting column 376 to slide, and further the connecting column 376 drives the five support rods 33 to slide inward, thereby driving the wiring harness to be gathered and arranged in a circular array on the wiring clamp 36, and further the wiring harness is gathered and passed through the clamping groove of the wire clamping plate 383, and the rotating block 389 is rotated, so that the rotating block 389 drives the first bevel gear 387 and the second bevel gear 388 to rotate, and then drives the bidirectional screw rod 381 to rotate, and then drives the two wire clamping plates 383 to clamp the wiring harness in opposite directions, so that multiple wiring harnesses are gathered together, and the liquid pump 44 is started to make the refrigerant circulate in the wire clamping plate 383, and the flow of the refrigerant is used to cool the wiring harness.

[0046] The above embodiments of the invention are described in detail, but the contents are only preferred embodiments of the invention and cannot be considered to limit the scope of the invention. All equivalent changes and improvements made within the scope of the invention should still fall within the scope of the invention.
