Referring to fig. 2 and 3, each of the first and

second ventilation walls

126 and 127 includes an outer panel 121 and a connection cover 122 fixed to one side of the outer panel 121. Locking rims 13 are provided at both ends of the housing 11, and the locking rims 13 extend toward the inside of the housing 11. When the ventilation wall 12 is fixed to the housing 11, the outer panel 121 abuts against the side surface of the locking rim 13 perpendicular to the housing 11 and is fixedly connected by screws, and the connecting cover 122 is inserted into the housing 11.

Referring to fig. 4, a plurality of strip-shaped first ventilation holes 123 are sequentially arranged on the outer plate 121 at intervals in the width direction, the connecting cover 122 is surrounded by four trapezoidal connecting plates 1221, the bottom edge of each connecting plate 1221 is fixed on the outer plate 121 and has a certain distance from the edge of the outer plate 121, and the adjacent edges of two adjacent connecting plates 1221 are fixed. Therefore, the four connecting plates 1221 are obliquely arranged on the outer plate 121, and the connecting cover 122 gradually converges toward the end far away from the outer plate 121. A dust suction net 124 is fixed to a port of the connecting cover 122 on the side away from the outer plate 121.

Referring to fig. 2 and 3, when the ventilation wall 12 is fixed on the housing 11, the connecting cover 122 abuts against the side wall of the abutting plate 16, and since the abutting plate 16 is deformable and since the abutting plate 16 has a certain thickness, when the connecting cover 122 pushes the abutting plate 16, the abutting plate 16 is squeezed between the connecting cover 122 and the inner layer wall 14, so that the ventilation wall 12 is connected with the housing 11 more tightly.

Since the components in the housing 11 are dense and heat dissipation is slow, the exhaust fan 128 is disposed between the outer plate 121 of the first ventilation wall 126 and the dust suction net 124. Referring to fig. 5, the components in the housing 11 include a controller 3, a temperature sensor 4 is further disposed in the housing 11 near the bottom side wall, the temperature sensor 4 and the exhaust fan 128 are both connected to the controller 3, and the controller 3 is connected to the display screen 2. The controller 3 receives the temperature detected by the temperature sensor 4 and controls the temperature to be displayed on the display screen 2 in real time, after the temperature sensor 4 detects that the temperature in the shell 11 is higher than a preset temperature value, the controller 3 controls the exhaust fan 128 to be started, and when the exhaust fan 128 is turned on, the exhaust fan 128 exhausts the hot air of the shell 11. Wherein the preset temperature value is a critical temperature value when having an influence on the operation of the equipment.

Referring to fig. 2 and 3, since the dust suction net 124 has fine meshes and is poor in ventilation effect, a connection pipe group 5 is provided in the cavity 17 to communicate the cavity 17 with the inside of the ventilation wall 12. When the exhaust fan 128 is started, a part of air in the housing 11 can be exhausted from the dust collection net 124, and another part of air can enter the ventilation wall 12 through the cavity 17 and the connecting pipe group 5, so that the air flow speed is increased; in addition, if there is a lot of dust stuck on the dust collection net 124 and the dust is not cleaned, the air in the housing 11 is more difficult to flow out smoothly, so the air can be discharged out of the housing 11 through the connection pipe group 5 directly.

The connecting tube groups 5 are arranged in groups at the centers of both sides of the top end and the bottom end of the cavity 17. The connecting tube group 5 comprises a fixed tube 51 fixed on the inner wall of the shell 11, one end of the fixed tube 51 close to the abutting plate 16 is fixed with a telescopic corrugated tube 52, the other end of the corrugated tube 52 is fixed with a connecting tube 53, the connecting tube 53 is bent into a right angle, one end is fixed with the corrugated tube 52, and the extension direction of the other end is parallel to the plane of the outer plate 121.

If only a part of air is discharged from the dust collection net 124 on the first ventilation wall 126 due to the dense mesh of the dust collection net 124 on the first ventilation wall 126 or the dust on the dust collection net 124 is not cleaned in time, the hot air near the top and bottom side walls in the housing 11 can be brought into the cavity 17 through the second ventilation holes 15 on the inner wall 14, and then the hot air enters the first ventilation wall 126 through the connection pipe group 5 and is discharged through the first ventilation holes 123, so that the hot air in the housing 11 circulates and the heat dissipation speed is high.

Referring to fig. 2 and 5, an air velocity sensor 7 is disposed in the housing 11 near the dust collection net 124 on the second ventilation wall 127, the air velocity sensor 7 is connected to the controller 3, when the exhaust fan 128 is started, the air velocity sensor 7 is configured to detect an air velocity near the second ventilation wall 127, if the air velocity is less than a preset air velocity value, that is, there is more dust on the dust collection net 124 on the second ventilation wall 127, and the speed of the outside cold air entering the housing 11 becomes slow, then the controller 3 controls the display screen 2 to display air velocity data, and when the air velocity data is less than the preset air velocity value, the worker cleans the dust collection net 124.

Referring to fig. 4, a first notch 1211 is formed in the outer plate 121 at a position facing the connection pipe 53, and a second notch 131 is formed in the locking edge 13 at a position facing the connection pipe 53. referring to fig. 1, a hinge plate 125 is hinged to a bottom edge of the first notch 1211, and the hinge plate 125 is fixed to the housing 11 by a screw. The first notch 1211 is larger than the second notch 131 so that when the hinge plate 125 is secured to the housing 11, the hinge plate 125 completely covers the second notch 131 to enhance the seal.

Referring to fig. 4 and 6, when the dust collection net 124 is cleaned, the screw on the outer plate 121 is screwed down, the first ventilation wall 126 and the second ventilation wall 127 are respectively pulled in a direction away from the housing 11, the bellows 52 is elongated, the hinge plates 125 on the outer plate 121 are rotated to open, after the connection pipe 53 is completely pulled out of the housing 11, the connection pipe 53 is vertically slid to be away from the connection cover 122, and the connection pipe 53 does not slide out of the connection cover 122 because the stopper pipe abuts against the inner wall of the connection cover 122. Then, the connecting pipe 53 is suspended outside the edge of the ventilation wall 12, and the ventilation wall 12 is rotated so that the ventilation wall 12 is rotated 180 degrees about the connecting pipe 53 connected to the upper and lower sides thereof. The dust collection net 124 is exposed, then the connecting pipe 53 is vertically slid, the connecting pipe 53 is slid back into the connecting cover 122 again, then the ventilation wall 12 is pushed to shorten the corrugated pipe 52, the connecting pipe 53 is inserted into the supporting frame 6, the outer plate 121 is abutted against the end part of the shell 11, the outer plate 121 can be fixed on the shell 11, and the dust collection net 124 is cleaned. Dust falling from the dust collection net 124 is effectively prevented from entering the housing 11 when the dust collection net 124 is cleaned.

The implementation principle of the wireless communication network signal coverage analyzer in the embodiment of the application is as follows: the temperature sensor 4 detects the temperature in the housing 11, and after the controller 3 receives the signal sent by the temperature sensor 4, the controller 3 controls the display screen 2 to display the temperature.

After temperature sensor 4 detects the temperature rise in casing 11, controller 3 controls exhaust fan 128 to start, and after exhaust fan 128 started, exhaust fan 128 drafts outward, receives the atmospheric pressure influence, and the outside air enters into casing 11 through second ventilation wall 127. Dust in the air is intercepted on the dust collection net 124, and is prevented from entering the shell 11 to influence the components.

A part of the external cold air passes through the dust suction net 124 of the second ventilation wall 127 and is discharged from the first ventilation hole 123. The hot air in the housing 11 near the upper and lower side walls enters the cavity 17 through the second vent hole 15 in the inner side wall, then enters the first vent wall 126 through the connecting tube group 5, and finally is discharged from the first vent hole 123.

When the exhaust fan 128 is started, the wind speed sensor 7 sends a signal to the controller 3, and when the wind speed is less than the preset wind speed, the controller 3 makes the display screen 2 display the wind speed.
