[0001] The utility model relates to the technical field of electric power construction, in particular to a portable test electric box for electric power construction. Background Art

[0002] During power construction, a test box is required to test the power. The existing test box is usually closed. When the box is working under high load, the heat in the box is not easy to dissipate. For example, in the patent number "CN214958214U" and the patent name "A Power Construction Test Box", both sides of the outer wall of the box are connected with a number of dustproof windows arranged at equal distances, and a number of first through holes are opened at equal distances on both sides of the inner wall of the box, and the first through holes are connected with the dustproof windows. However, the above structure still has the following problems in actual use:

[0003] A lot of dust will be generated during the power construction process. However, after the above-mentioned test electrical box has been used for a long time, a large amount of dust will be absorbed on the surface of the dustproof window. If it is not cleaned in time, the dust will block the air, thereby reducing the heat dissipation effect.

[0004] Therefore, we proposed a portable test box for power construction that can solve the above problems well. Utility Model Content

[0005] The purpose of the utility model is to provide a portable test electrical box for power construction, so as to solve the problem raised by the above-mentioned background technology that after the test electrical box on the market is used for too long, a large amount of dust will be absorbed on the surface of the dustproof window. If it is not cleaned in time, the dust will block the air, thereby causing a decrease in the heat dissipation effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a portable test electric box for electric power construction, comprising a box body, wherein a box cover is hingedly connected to the upper end of the box body;

[0007] It also includes: a servo motor is fixed by bolts inside the box, a shaft is fixed at the output end of the servo motor, the upper end of the shaft is connected to the box bearing, and a sprocket assembly is fixed on the outer side of the shaft;

[0008] A worm is fixed inside both ends of the sprocket assembly, and the upper and lower ends of the worm are connected to the box bearing. A worm wheel is meshed on the outer side of the worm, and a rotating shaft is fixed in the middle of the worm wheel. A cleaning rod is fixed on the outer end of the rotating shaft.

[0009] Preferably, the sprocket assembly is provided with a group of driving sprockets and two groups of driven sprockets, and a linkage structure is formed between the driving sprockets and the driven sprockets through a chain.

[0010] Preferably, a filter screen is fixed by bolts on both sides of the box body, and a cleaning rod is placed on the outer surface of the filter screen, and a brush is bonded to the inner side of the cleaning rod, and the brush is in close contact with the filter screen.

[0011] Preferably, a heat dissipation fan is fixed to the outer side surface of the rotating shaft, and the inner end of the rotating shaft is connected to the box bearing, and a through hole is opened on the inner wall of the box.

[0012] Preferably, a roller is fixedly mounted on the lower surface of the box body, and a fitting groove is provided on the upper surface of the box cover.

[0013] Preferably, a pull rod is fitted inside the fitting groove, and the pull rod is in a "U"-shaped structure, and the rear end of the pull rod is rotatably connected to the box cover, and a clamping hole is opened on the outer side of the pull rod.

[0014] Preferably, a clamping block is clamped inside the clamping hole, and the clamping block is slidably connected to the box cover via a return spring, and two ends of the return spring are respectively fixed to the clamping block and the box cover.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the portable test box for electric power construction not only does not need to be cleaned manually, but also avoids dust adhering to the filter surface and affecting the heat dissipation effect, and achieves the effect of heat dissipation for the electronic components inside the box, thereby avoiding the over-high temperature of the test box affecting the normal operation of the electronic components, and is convenient to move the box as a whole, and is easy to use. The specific contents are as follows:

[0016] (1) The shaft rotates, thereby driving the cleaning rod to rotate together, and a brush is bonded to the inner side of the cleaning rod, and the brush fits the surface of the filter, so that the cleaning rod cleans the dust on the surface of the filter through the brush, thereby eliminating the need for manual cleaning and preventing dust from adhering to the surface of the filter to affect the heat dissipation effect;

[0017] (2) Furthermore, a driving sprocket is connected to two driven sprockets and chains to form a linkage structure, so that the sprocket assembly drives the two worms to rotate together, and the worm drives the meshing worm wheels to rotate together, and the rotation of the worm wheels drives the fixed shaft in the middle to rotate;

[0018] (3) When the shaft rotates, the shaft also drives the cooling fan to rotate, so that it can inhale external air. The air inhaled by the cooling fan enters the box through the through hole, thereby achieving the effect of cooling the electronic components inside the box, thereby preventing the temperature of the test box from being too high and affecting the normal operation of the electronic components;

[0019] (4) When the entire box needs to be moved, the pull rod only needs to be moved upward to separate the inner end of the card block from the card hole. At this time, the pull rod can be pulled out of the fitting groove, and then the box can be moved by the rollers under the box to achieve a portable effect;

[0020] (5) By pressing the pull rod back into the engagement groove, the block is forced to slide outward. When the pull rod drives the engagement hole to be parallel to the block, the elastic force of the reset spring drives the block to engage with the engagement hole again, thereby limiting the pull rod.
