[0040] The present invention is described below based on the embodiments shown in the accompanying drawings. The embodiments disclosed this time can be considered to be illustrative in all aspects and not restrictive. The scope of the present invention is not limited by the description of the following embodiments, but is only shown by the scope of the claims, and includes all variations with the same meaning as the scope of the claims and within the scope of the claims.

[0041] The structure of the discharge and ventilation system of an underground pressure regulating box of the utility model is explained below in conjunction with specific embodiments.

[0042] like Figure 1 , Figure 2 As shown, the utility model discloses a dispersion and ventilation system for an underground pressure regulating box, which includes a dispersion and ventilation system body and a control system for controlling the air intake interval time and the single air intake duration.

[0043] The main body of the dispersion and ventilation system includes a first air inlet pipe 1, a first air outlet pipe 2 and a first dispersion pipe 3. The first air inlet pipe 1, the first air outlet pipe 2 and the first dispersion pipe 3 of this embodiment are all made of PE pipes. The first air inlet pipe 1 is connected between the air inlet of the underground pressure regulating box 4 and the air inlet of the dispersion tower 5. The dispersion tower 5 is fixed to the ground by anchor bolts. The dispersion tower 5 has a second air inlet pipe 6, a second air outlet pipe 8 and a second dispersion pipe 10. The second air inlet pipe 6, the second air outlet pipe 8 and the second dispersion pipe 10 are all located in the inner cavity of the dispersion tower 5. Figure 3 and Figure 4 As shown, the first air inlet pipe 1 is connected to the second air inlet pipe 6 of the discharge tower 5 through the air inlet of the discharge tower 5, and the second air inlet pipe 6 is connected to the blowing device. The blowing device of this embodiment adopts a blower motor 7. The first air outlet pipe 2 is connected between the air outlet of the underground pressure regulating box 4 and the air outlet of the discharge tower 5. The first air outlet pipe 2 is connected to the second air outlet pipe 8 of the discharge tower 5 through the air outlet of the discharge tower 5. The upper end of the second air outlet pipe 8 passes through the discharge tower 5 upward. The first discharge pipe 3 is connected between the discharge valve 9 of the underground pressure regulating box 4 and the discharge port of the discharge tower 5, and the first discharge pipe 3 is connected to the second discharge pipe 10 of the discharge tower 5 through the discharge port of the discharge tower 5. The upper end of the second discharge pipe 10 passes through the discharge tower 5 upward.

[0044] Combination Figure 3 , Figure 4As shown, the upper end of the discharge tower 5 is rotatably mounted with a non-powered hood 11, and the upper ends of the second air outlet pipe 8 and the second discharge pipe 10 pass through the non-powered hood 11. A flame arrester 12 is installed between the upper end of the discharge tower 5 and the non-powered hood 11, and the upper ends of the second air outlet pipe 8 and the second discharge pipe 10 pass through the flame arrester 12.

[0045] The blower motor 7 is connected to a power supply device, and the power supply device in this embodiment adopts a solar panel 13. The solar panel 13 is installed on the upper part of the discharge tower 5.

[0046] The control system includes a control box 14 and a control module 15 for controlling the operation of the blower motor 7, thereby controlling the air intake interval time and the single air intake duration. The control module 15 is installed in the inner cavity of the control box 14, and the control box 14 is fixedly installed in the middle position of the outer surface of the discharge tower 5.

[0047] During normal operation, the blower motor 7 powered by the solar panel 13 works, so that fresh air enters the inner cavity of the underground pressure regulating box 4 through the second air inlet pipe 6 and the first air inlet pipe 1. Since the underground pressure regulating box 4 is closed, the air pressure entering the underground pressure regulating box 4 gradually increases, and then enters the second air outlet pipe 8 inside the discharge tower 5 along the first air outlet pipe 2, and is discharged into the atmosphere through the unpowered wind cap 11 at the upper end of the discharge tower 5. When the solar energy is deficient, the unpowered wind cap 11 rotates under the action of the atmospheric wind force. Since the second air outlet pipe 8 and the unpowered wind cap 11 are sealed, the space enclosed by the discharge tower 5, the unpowered wind cap 11 and the second air outlet pipe 8 is a closed space, thereby forming a negative pressure in the closed space. The air in the underground pressure regulating box 4 is discharged into the closed space of the discharge tower 5 under the action of negative pressure, so that the air pressure in the underground pressure regulating box 4 is reduced, and fresh air enters the second air inlet pipe 6 through the blower motor 7, and enters the inner cavity of the underground pressure regulating box 4 through the first air inlet pipe 1 to form a cycle, so as to always keep the air flow in the underground pressure regulating box 4. Through the action of the blower motor 7 or the unpowered wind cap 11, the underground pressure regulating box 4 can be kept dry, and the combustible gas discharged into the underground pressure regulating box 4 due to equipment leakage can also be taken away, so as to prevent the accumulation of combustible gas and reduce the risk of explosion. When the discharge valve 9 is opened, the combustible gas enters the first discharge pipe 3 and the second discharge pipe 10 under the action of the discharge pressure, and is finally discharged at the top of the discharge tower 5. By setting a flame arrester 12 at the upper end discharge port of the discharge tower 5, it can prevent electric sparks such as lightning from being introduced into the second discharge pipe 10 to cause explosion and other accidents.

[0048] In addition, the blower motor 7 works at intervals set by the control module 15, which can save solar power.

[0049] The utility model combines the existing ventilation system and the discharge system into one, and its on-site construction and installation are more convenient. By combining the blower motor 7 and the unpowered wind hood 11, the unpowered wind hood 11 can be used as a supplementary ventilation mode when solar energy is insufficient to ensure that the ventilation system is uninterrupted. By using the solar panel 13 as the power supply equipment, the overall energy saving, environmental protection and pollution-free are achieved. By installing a flame arrester 12 between the top of the discharge tower 5 and the unpowered wind hood 11, it can be ensured that open flames do not enter the interior of the discharge system, and safety is better. By controlling the air intake interval time and the single air intake duration through the control system, the power of the solar panel 13 can be reasonably utilized. By connecting the first air inlet pipe 1, the first air outlet pipe 2 and the first discharge pipe 3 with PE pipes, the cost is lower and the installation is more convenient.

[0050] The above-described embodiments are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope of the claims of the present invention.
