Description

Technical Field

[0001] The utility model belongs to the field of energy storage cabinet monitoring, and in particular relates to a gas detection device for an energy storage cabinet. Background Art

[0002] In recent years, with the increase in my country's energy demand and the rapid development of new energy, energy storage technology has gradually become a hot topic in various fields. As an important device, energy storage cabinets play an important role in the energy field. Energy storage cabinets are devices for storing electrical energy. It uses advanced energy storage technology to store electrical energy when the power supply is sufficient, and release electrical energy when the demand is peak or the power is insufficient. Energy storage cabinets are composed of components such as battery packs, control systems, and input and output interfaces. It has the characteristics of high energy density, fast response and long life, and has become a key component of modern energy systems. Energy storage cabinets can be used in many fields, including new energy power stations, smart microgrids, electric vehicle charging piles, industrial power reserves and household energy storage. First of all, for new energy power stations, energy storage cabinets can effectively solve the intermittent and uncontrollable problems of renewable energy. When the power generated by new energy power generation equipment such as wind turbines or solar panels exceeds the demand, the excess power can be stored in energy storage cabinets for emergency use. Conversely, when the power generated by new energy power generation equipment is insufficient, the energy storage cabinet can quickly release the stored power and provide it to the power system for use to ensure stable power supply.

[0003] In the daily production process, the monitoring and maintenance of energy storage cabinets are mainly carried out by manual inspections. Since electrical equipment will produce burnt odor gas when it is aged, faulty or short-circuited and overloaded, it is mainly through the sense of smell that people distinguish whether there is burnt odor gas around the energy storage cabinet to judge whether the electrical equipment in the energy storage cabinet has failed. However, the workload of manual inspections is large, which increases the work intensity of the inspectors. In addition, the human sense of smell is limited, and it is impossible to detect weak odors in time, resulting in the problem of missed inspections. Utility Model Content

[0023] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] For ease of description, spatially relative terms, such as "under", "below", "down", "above", "upper", etc., will be used when necessary to describe the relationship of one element or feature relative to another element or feature shown in the drawings. The spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation shown in the drawings.

[0026] See also Figure 1 For example, a gas detection device for an energy storage cabinet includes:

[0027] A cabinet 10 is provided with a receiving cavity;

[0028] The air extraction device comprises a storage member 20 having a sampling chamber 21, an air pump (not shown in the figure) and a conduit 30, wherein the storage member is arranged on the top of the cabinet, the sampling chamber 21 is connected to the accommodating cavity through the air outlet 11 on the top of the cabinet, and the air pump is connected to the sampling chamber 21 through the conduit 30;

[0029] A gas sensor array is arranged in the sampling chamber and is used to detect the concentration of the gas to be measured;

[0030] The display unit is embedded in the cabinet door of the cabinet and is electrically connected to the gas sensor array to display gas concentration data.

[0031] The gas sensor detects the gas concentration generated by the energy storage cabinet at all times and transmits it to the display unit. The display unit processes the gas concentration data. When the concentration is low, the data will only be displayed on the data display unit. When the measured gas concentration is high, higher than the standard value, the display unit will trigger the alarm to sound an alarm, and then the wireless transmission module will transmit it to the set equipment management personnel or monitoring center, so that the management personnel can quickly handle it after receiving the prompt.

[0032] In one embodiment, the sensor array includes but is not limited to a CO sensor, a NO sensor, a NO2 sensor, an O3 sensor, and a CO2 gas sensor. The CO sensor, the NO sensor, the NO2 sensor, the O3 sensor, and the CO2 gas sensor are electrically connected to the display unit, respectively.

[0033] like Figure 2 As shown, the energy storage cabinet gas detection device also includes an alarm, which is coupled to the display unit. When the gas concentration detected by the gas sensor array is greater than a threshold, the display unit controls the alarm to remind the electrical equipment in the energy storage cabinet of a fault.

[0034] A one-way valve is provided at the air outlet on the top of the cabinet, and an electric valve is provided on the conduit to isolate external air by opening or closing, so that the extracted air stays in the detection room to improve the detection accuracy.

[0035] The conduit is provided with a filtering device, which selects one or a combination of an air filter for filtering air, a liquid filter, a bacterial filter and a gas filter that selectively allows or prevents compounds from passing through. When the device is sucked out, liquids such as water vapor are usually also exhaled. This liquid filter and bacterial filter can be formed by the same filter. An example of such a filter is a high-efficiency particulate air (HEPa) filter. However, it is important that the filter applied is porous enough so that when sucking out the air, it is relatively easy to blow the exhausted air through the filter without causing great inconvenience to the person. When such a filter is used, the exhausted liquid and / or bacteria will remain in the filtering device. The gas filter will allow characteristic chemical traces to pass through the conduit, while other gaseous compounds, such as one or more inert gases and / or one or more gases can be removed. The selective gas filter is also usually configured as a liquid filter and can also be selectively configured as a bacterial filter.

[0036] The display unit is equipped with a wireless transmission module, and the wireless transmission module transmits gas concentration data to a monitoring center. The display unit is a display screen.

[0037] The energy storage cabinet gas detection device also includes a controller, which controls the opening and closing of the one-way valve and the electric valve.

[0038] The energy storage cabinet gas detection device also includes a temperature sensor, which is arranged in the cabinet. When the temperature value detected by the temperature sensor is greater than a threshold value, a first signal is generated, and when the gas sensor array detects that the concentration of the gas to be tested is greater than a preset value, a second signal is generated. The display unit receives the first signal and the second signal and generates a fault signal, which can confirm that the electrical equipment in the energy storage cabinet has a fault, and sends the fault signal to the equipment management personnel or the monitoring center, so that the management personnel can quickly handle it after receiving the prompt.

[0039] The specific implementation modes of the present invention are described above, but the present invention is not limited thereto. The present invention can also have various changes without departing from the purpose of the present invention.
