This device prevents coal ash and impurities from falling onto the housing and damaging its exterior and interior, while also facilitating disassembly and maintenance. It also facilitates the fixing of electrical wires, preventing them from loosening due to shaking, and makes maintenance easier. Furthermore, it makes full use of space for ventilation, expanding the ventilation area without affecting airflow and cleaning.

[0009] Through the above technical solution design, the wires are connected to the socket inside the box, the protective mechanism prevents coal ash impurities from impacting the box, the fixing mechanism locks the connection between the wires and the box to prevent the wires from shaking and becoming loose, and the ventilation mechanism plays a role in heat dissipation and at the same time prevents dust from accumulating inside the box, making the dust easy to clean.

[0010] Preferably, the protective mechanism comprises:

[0011] The protective cover, which is located on the box, has an umbrella-shaped structure; a connecting rod is fixed in the middle of the inner top plate of the protective cover.

[0012] The positioning post is located below the protective cover. A ball groove is opened on the top of the positioning post, and a rotating ball is movably embedded in the ball groove. The upper end of the rotating ball is fixed to the connecting rod. The positioning post is connected to the box body through a limiting mechanism.

[0013] The springs are numerous and are fixed in a ring shape on the upper part of the ring wall of the positioning post; the upper end of the spring is fixed to the protective cover.

[0014] Through the above technical solution design, the positioning column is fixed to the box body by the limiting mechanism; when coal ash impurities fall, the stones fall on the protective cover, the rotating ball under the connecting rod rotates in the ball groove, the protective cover shifts, and under the action of the spring, the vibration of the protective cover is relieved and returned to its position, avoiding damage to the box body.

The positioning pin is placed on the limiting rod, and the limiting rod is rotated by hand. The limiting rod rotates to a horizontal position through the first and second annular grooves respectively, causing the positioning pin to be locked.

[0020] Preferably, the front end of the No. 1 screw is connected to the rear output shaft of the steering gear;

When the door 5-1 is closed, the limiting rubber pad 5-2 is in contact with the wire. Rotating the rotating block 5-5 causes the second screw 5-4 to rotate. Under the action of the limiting plate 5-3, the limiting rubber pad 5-2 is driven to lock the wire, preventing the wire from shaking and becoming loose.

[0077] Example 5:

[0078] Please see Figure 2 and Figure 6 Based on embodiments 2 and 4, the ventilation mechanism 6 includes:

[0079] Fan 6-1, there are four fans 6-1, and they are respectively embedded and fixed on the top plate of the housing 1; the fans 6-1 are connected to an external power supply, and the specific model of the fans 6-1 is purchased directly from the market and installed and used according to the actual use requirements;

The filter screen 6-2 filters out coal ash impurities, which fall into the collection pipe 6-3 under the action of gravity, maintaining ventilation. The blown air blows downward through the slot 1-2 to prevent dust accumulation at the bottom of the housing 1. When inspecting the inside of the housing 1, the door 5-1 is opened and the filter screen 6-2 is removed for cleaning.

[0083] In use, rotating the hand screw 4-5-9 causes the first screw 4-5-7 to rotate, which in turn rotates the internal threaded tube 4-5-6, causing the limiting rod 4-5-3 to rotate to a horizontal position. The positioning pin 4-3 is then placed on the limiting rod 4-5-3. Rotating the hand screw 4-5-9 causes the limiting rod 4-5-3 to rotate, and the limiting rod 4-5-3 rotates to a horizontal position through the first annular groove 4-3-2 and the second annular groove 4-3-3, respectively, thus locking the positioning pin 4-3 and fixing it to the housing 1. When the door 5-1 is opened and the wire is connected to the power strip 3, the wire is secured in the slot 1-2. Closing the door 5-1 allows the limiting rubber pad 5-2 to contact the wire. Rotating the rotating block 5-5 causes the second screw 5-4 to rotate, which, under the action of the limiting plate 5-3, drives... Limiting rubber pad 5-2 secures the wires, preventing them from loosening due to swaying. Fan 6-1 is activated to draw external air into housing 1. Protective cover 4-1 prevents falling stones and impurities from entering fan 6-1. Filter screen 6-2 filters coal ash and impurities, which fall into collection pipe 6-3 under gravity, maintaining ventilation. The blown air is directed downwards through slot 1-2, preventing dust accumulation at the bottom of housing 1. When inspecting housing 1, open door 5-1 and remove filter screen 6-2 for cleaning. When coal ash or impurities fall, stones land on protective cover 4-1. The rotating ball 4-4 below the connecting rod rotates within ball groove 4-3-1, causing protective cover 4-1 to shift. Spring 4-6 mitigates the vibration of protective cover 4-1 and returns it to its original position, preventing damage to housing 1.
