Description

Technical Field

[0001] The invention relates to the technical field of energy storage, and in particular to an energy storage explosion relief plate device. Background Art

[0002] With the continuous development of energy storage technology, energy storage containers are an important part of energy sources such as photovoltaic power stations and wind-solar complementary power stations. Including cabinets and energy storage batteries, the safety of the entire energy storage battery cabinet is very important. When the battery has thermal runaway, it will cause a large amount of flammable gas to accumulate, and the pressure inside the cabinet will rise rapidly, which can easily lead to the risk of cabinet explosion, seriously endangering equipment and personal safety.

[0003] At present, there are mainly the following types of explosion venting panels.

[0004] The first method is to use a venting disc, which is welded from two pieces of blasting membranes. The slit method uses three-sided slits as the blasting membrane, and releases the pressure by breaking the blasting membrane through the pressure force. The disadvantage of this method is that due to the slit treatment, there will inevitably be gaps, which will cause poor sealing and the risk of water and mist entering, which will affect the temperature inside the container. The second is the strength problem. There is no outer shell protection. It is welded from two layers of pre-slit films and cannot resist wind, snow and hail.

[0005] The second type: The second type is evolved from the first type. The overall structure consists of a protective cover, thermal insulation cotton, mounting flange, bursting membrane, and sealing gasket. This method adds a protective cover, thermal insulation cotton, and mounting bracket, and the opening direction is to one side. The protective cover of this method has a certain improvement in strength and thermal insulation performance, but the strength and sealing of this type of solution are also limited. In terms of strength: one side is fixed, and the three sides are not fixed, which means that if there is lateral wind pressure, the protective cover may be easily blown open. Secondly, in terms of sealing: the three sides are fixed, the gap between the protective cover and the thermal insulation cotton, the gap between the mounting flange and the thermal insulation cotton, and the gap between the blasting membrane are all gaps, and air exchange is possible, and water mist and moisture enter.

[0006] In addition, in terms of pressure control: the current traditional design of the protective cover is to open the protective cover by air pressure, which uses the toughness of the protective cover to bend and deform it, thereby opening the protective cover and achieving the purpose of explosion relief. The disadvantage of this solution is that it has a resistance effect on the opening pressure. Since the protective cover is in the external environment, it is very easy to be physically affected by environmental factors on the characteristics of the material, thereby affecting the explosion relief pressure. Summary of the invention

[0007] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide an energy storage explosion relief plate device that can solve the problem that the protective cover is very susceptible to physical influences on the material properties due to environmental factors in the external environment.

[0008] To achieve the above object, the present invention provides the following technical solutions: an energy storage explosion relief plate device, comprising a protective cover and a C-shaped channel steel, wherein the C-shaped channel steel is a client cabinet structure, a thermal insulation cotton is installed on the bottom surface of the protective cover, a sealing gasket is pasted on the bottom surface of the thermal insulation cotton, a mounting bracket is installed on the bottom surface of the sealing gasket, a lower gasket is installed on the bottom surface of the mounting bracket, and the bottom surface of the lower gasket is connected to the C-shaped channel steel;

[0009] Wherein, a fixing screw is installed on the mounting bracket, a rivet bolt assembly is installed on the C-shaped channel steel, the fixing screw is connected with the rivet bolt assembly, and the mounting bracket, the lower gasket and the C-shaped channel steel are connected together by the fixing screw and the rivet bolt assembly;

[0010] Among them, an explosion-relief pin is installed on the ground of the protective cover, and the mounting bracket is connected to the protective cover through the explosion-relief pin. A spring hinge is installed on the mounting bracket, and the spring hinge is connected to the protective cover.

[0011] Preferably, the protective cover has a double-opening type and a single-opening type. The double-opening type opens from the middle to both sides, and the single-opening type opens from one side to the other side.

[0012] Preferably, the mounting bracket is flange mounted and mounted one-to-one with a flange preset in the container, and can be fixed with common screws, nuts and gaskets.

[0013] Preferably, the thermal insulation cotton is fixedly installed inside the protective cover by fully gluing the inside of the protective cover.

[0014] Preferably, the middle portion of the mounting bracket is provided with reinforcing ribs.

[0015] Preferably, the protective cover is hinged to the mounting bracket via a spring hinge.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The energy storage explosion relief plate device has a double-opening protective cover, and a sealing gasket is provided at the bottom of the protective cover. At the same time, the sealing gasket has a pre-compression locking force to ensure the sealing effect. A stamping and stretching shape is designed on the top of the protective cover to enhance the strength of the protective cover. An explosion relief pin is used in the explosion relief pressure control device. Its main function is to accurately control the opening pressure design. At the moment when the protective cover is opened by pressure, the protective cover will open along the preset direction along the hinges on both sides. This design can reduce other resistances in the process from the explosion relief plate to the explosion relief, thereby improving the control of the explosion relief accuracy.

[0025] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0026] See also Figure 1-2 The present invention provides a technical solution: an energy storage explosion relief plate device, comprising a protective cover 1 and a C-shaped channel steel 10, the C-shaped channel steel 10 is a client cabinet structure, a thermal insulation cotton 3 is installed on the bottom surface of the protective cover 1, a sealing gasket 4 is pasted on the bottom surface of the thermal insulation cotton 3, a mounting bracket 6 is installed on the bottom surface of the sealing gasket 4, a lower gasket 7 is installed on the bottom surface of the mounting bracket 6, and the bottom surface of the lower gasket 7 is connected to the C-shaped channel steel 10;

[0027] Among them, a fixing screw 8 is installed on the mounting bracket 6, a rivet bolt assembly 9 is installed on the C-shaped channel steel 10, the fixing screw 8 is connected with the rivet bolt assembly 9, and the mounting bracket 6, the lower gasket 7 and the C-shaped channel steel 10 are connected together by the fixing screw 8 and the rivet bolt assembly 9;

[0028] Among them, the ground of the protective cover 1 is installed with an explosion relief pin 2, the mounting bracket 6 is connected to the protective cover 1 through the explosion relief pin 2, the mounting bracket 6 is installed with a spring hinge 5, the spring hinge 5 is connected to the protective cover 1, and the protective cover 1 is hinged with the mounting bracket 6 through the spring hinge 5;

[0029] Furthermore, the protective cover 1 has a double-opening type and a single-opening type. The double-opening type is opened from the middle to both sides, and the single-opening type is opened from one side to the other side.

[0030] Furthermore, the mounting bracket 6 adopts a flange mounting type, which is installed just one-to-one with the preset flange of the container. The installation and fixing can be fixed by ordinary screws, nuts and gaskets. When there are special requirements for the installation height, rivet nuts can also be used for installation;

[0031] Furthermore, the function of the spring hinge 5 is that when the explosion relief pin breaks 2, the protective cover 1 can be instantly pushed open by the spring hinge 5 alone, thereby accelerating the explosion relief speed. When the air pressure is insufficient, the spring on the spring hinge 5 plays an auxiliary role in opening and preventing the cover from being covered again.

[0032] Furthermore, the explosion relief pressure control mechanism adopts an explosion relief pin. When the air pressure reaches the preset pressure, the air pressure will push open the protective cover and indirectly break the explosion relief pin to achieve the purpose of accurately controlling the explosion relief pressure. The method described in this figure is to break it in the vertical direction. In addition, if the explosion relief pin is placed horizontally, or the explosion relief gasket is used, the explosion relief pin is broken by shear stress.

[0033] Furthermore, the insulation cotton 3 is fixedly installed inside the protective cover 1 by a full-sticking method, and the insulation treatment can also be performed by spraying a polyurethane foaming agent;

[0034] Furthermore, in order to strengthen the strength of the protective cover 1 and resist the interference of external factors on the protective cover 1, a reinforcing rib is provided in the middle part of the mounting bracket 6, which can greatly improve the strength of the protective cover 1, especially for severe weather such as wind, snow, hail, etc., which requires a relatively high reliability of the strength of the protective cover 1;

[0035] Furthermore, the protective cover 1 is double-open, and a sealing gasket 4 is provided at the bottom of the protective cover 1, and the sealing gasket 4 has a pre-compression locking force, which can ensure the sealing effect. A stamping and stretching shape is designed on the top of the protective cover 1, which can enhance the strength of the protective cover 1. The explosion relief pin is used in the explosion relief pressure control device, and its main function is to accurately control the opening pressure design. At the moment when the protective cover 1 receives pressure to open, the protective cover 1 will open along the hinges on both sides of the protective cover 1 in a preset direction. Through this design, other resistances in the process from the explosion relief plate to the explosion relief can be reduced, thereby improving the control of the explosion relief accuracy;

[0036] Furthermore, the explosion relief pressure control mechanism adopts an explosion relief pin. When the air pressure reaches the preset pressure, the air pressure will push open the protective cover and indirectly pull the explosion relief pin off to achieve the purpose of accurately controlling the explosion relief pressure. The method of pulling it off in the vertical direction described in this figure. In addition, if the explosion relief pin is placed horizontally, or an explosion relief gasket is used, the explosion relief pin is pulled off by shear stress.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
