Description

Technical Field

[0001] The utility model relates to the field of new energy storage technology, and in particular to a pressure relief valve for outdoor thin-walled energy storage containers. Background Art

[0002] The energy storage container is an energy storage device that is equipped with a battery cabinet, control system, fire protection system, etc. In order to prevent the internal pressure from damaging the container wall when the perfluorohexanone fire tank of the fire protection system is released, a pressure relief valve needs to be installed on the container wall.

[0003] Patent document with announcement number CN218793641U discloses a pressure relief device for a container energy storage system, including a welding assembly, a pressure relief sleeve, a pressure relief port mounting sleeve, a guide shaft assembly and a protective cover. The welding assembly is assembled on the container, the pressure relief sleeve is tightly connected to the pressure relief port mounting sleeve, the pressure relief port mounting sleeve is tightly and sealingly connected to the welding assembly, the guide shaft assembly is assembled on the welding assembly, and the protective cover is tightly connected to the guide shaft.

[0004] In order to meet the requirements of outdoor rain and dust protection, the existing pressure relief device is equipped with a protective cover on the outside of the pressure relief valve, which makes the overall thickness and weight too large. The installation requires the box wall thickness to be generally around 100mm, which is not suitable for thin-walled containers. It also occupies a large space inside the container, affecting the internal system layout of the container. Utility Model Content

[0005] The technical problem to be solved by the utility model is how to make the pressure relief valve suitable for thin-walled containers and meet the requirements of outdoor rain and dustproof use.

[0006] The utility model solves the above-mentioned technical problems through the following technical means: a pressure relief valve for outdoor thin-walled energy storage containers, comprising a cover plate, a rotating shaft, a valve body, a mounting frame and a louver plate; the cover plate is rotatably connected to the valve body through a rotating shaft, the valve body is mounted on the outside of the mounting frame, and the louver plate is mounted on the inside of the mounting frame; a pressure relief channel runs through the middle position of the valve body, the cover plate can be inserted into the valve body and cover the outer end of the pressure relief channel, and the portion between the outer periphery of the cover plate and the valve body is isolated from the pressure relief channel.

[0007] During pressure relief, the gas inside the container passes through the louver and valve body in turn and then breaks through the cover to be discharged out of the box; when the pressure is not relieved, the cover falls down to close the pressure relief channel; when the cover is inserted into the valve body, rainwater and dust entering the valve body through the gaps around the cover will not enter the pressure relief channel, but will flow out of the valve body along the outer periphery of the cover, thus preventing rainwater and dust from entering the louver. At the same time, the louver also has the function of blocking rainwater and dust, meeting the outdoor rain and dustproof requirements; the pressure relief valve is rainproof and dustproof through its own structure, without the need to add a protective cover, with small thickness and weight, and is suitable for thin-walled containers.

[0008] As an optimized technical solution, a first drainage trough is provided at the upper end of the pressure relief channel, and water guide grooves are respectively provided on the left and right sides of the pressure relief channel. The left and right ends of the first drainage trough are respectively connected to the gap below the pressure relief channel through water guide grooves for inserting the cover plate, and a first drainage hole is provided at the lower end of the cover plate.

[0009] Even if a small amount of rainwater enters the valve body from the inner edge of the cover plate, the rainwater will fall into the first drainage groove or the water guide groove, and eventually flow out of the valve body from the first drainage hole, further improving the protection effect.

[0010] As an optimized technical solution, the mounting frame includes a second drainage trough, which is a trough structure with an opening upward, and its opening covers the area corresponding to the lower end of the gap between the valve body and the louver; the lower end of the valve body is provided with a water outlet, and the lower end of the outer wall of the second drainage trough is provided with a second drainage hole, and the second drainage hole is connected to the water outlet.

[0011] Even if a small amount of rainwater enters the installation frame through the pressure relief channel, the rainwater will fall into the second drainage trough and then flow out of the valve body through the second drainage hole and the water outlet in sequence, further improving the protection effect.

[0012] As an optimized technical solution, the installation frame further includes a water baffle, which is separated between the upper portion of the pressure relief channel and the upper portion of the louver.

[0013] The water retaining plate can block rainwater entering the installation frame and guide the rainwater to flow into the second drain trough.

[0014] As an optimized technical solution, the lower end of the water baffle is provided with a first slope whose height gradually decreases from the inside to the outside, and the upper end of the inner wall of the second drainage trough is provided with a second slope whose height gradually decreases from the inside to the outside.

[0015] The first slope and the second slope can better guide the rainwater to flow down and ensure that the rainwater falls into the second drainage trough.

[0016] As an optimized technical solution, a first sealing strip is provided between the inner edge of the cover plate and the valve body.

[0017] The first sealing strip ensures the sealing between the cover plate and the valve body, further improving the protection effect.

[0019] The pressure relief valve is installed in the mounting hole on the container wall, taking up little space inside the container and not affecting the internal system layout of the container.

[0020] As an optimized technical solution, the valve body includes a valve body frame, which is located outside the container and the installation frame and is fixedly connected to the outer side of the box wall; the installation frame includes a mounting frame main body and a fourth flange, and the part of the valve body protruding from the inner side of the valve body frame is inserted into the mounting frame main body; the outer periphery of the mounting frame main body is provided with a fourth flange protruding from its upper side and left and right sides, and the fourth flange contacts the inner side of the box wall.

[0021] The valve body frame and the fourth flange are respectively clamped on both sides of the mounting hole on the box wall and are fixedly connected to the outer side surface of the box wall through the valve body frame. The structure is compact and the installation is convenient and firm.

[0022] As an optimized technical solution, the louver plate includes a louver structure and a fixed plate. The louver structure is inserted into the mounting frame and covers the area corresponding to the inner end of the pressure relief channel. The fixed plate is fixedly connected to the outer periphery of the louver structure. The fixed plate is located on the inner side of the louver structure and the mounting frame and is fixedly connected to the mounting frame.

[0023] The structure is simple, the production is convenient, and the protection effect is good.

[0024] As an optimized technical solution, a second sealing strip is provided between the louver plate and the mounting frame, and the second sealing strip is sleeved on the outer periphery of the louver structure.
