[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0022] Embodiment one
[0023] Please refer to Figures 1-6 The utility model provides an internal oil type oil storage cabinet with internal exhaust function, including cabinet bottom plate 1, cabinet bottom plate 1 is as the support base of device, and its upper surface installs two groups of corrugated core 2, and each group of corrugated core 2 sets a group of first exhaust pipe 3, and it is built in the inside of each group of corrugated core 2, and one end of first exhaust pipe 3 penetrates the bottom plate of corrugated core 2 and cabinet bottom plate 1 and is connected with gas collection box 4, is used for transmitting gas, and gas collection box 4 is set in the below of cabinet bottom plate 1, is used for collecting the gas from first exhaust pipe 3, and gas collection box 4 is connected with a group of second exhaust pipe 5, can exhaust the gas in gas collection box 4 to the external environment.
[0024] When the gas is generated inside the corrugated core 2, the gas will be transported through the first exhaust pipe 3, one end of the first exhaust pipe 3 penetrates the bottom plate of the corrugated core 2 and the cabinet bottom plate 1, and is connected with the gas collecting box 4 located below the cabinet bottom plate. In this way, the gas from the two groups of corrugated cores 2 will converge into the gas collecting box 4 through the respective first exhaust pipes 3. The gas collecting box 4 serves as a collection point for the gas and temporarily stores the gas from the corrugated core 2. The gas collecting box 4 is connected with a group of second exhaust pipes 5, which can safely and orderly release the gas in the gas collecting box 4 to the external environment,
[0025] Compared with the prior art, by embedding the first exhaust pipe 3 inside the corrugated core 2, it can ensure that the gas can be collected in time when it is generated, avoiding the leakage and waste of the gas. At the same time, the two-way first exhaust pipe 3 converges the gas into the gas collecting box 4, and then discharges it through the second exhaust pipe 5, which improves the efficiency and orderliness of gas discharge. The design of the device enables the corrugated core 2, the first exhaust pipe 3, the gas collecting box 4 and the second exhaust pipe 5 to be closely combined together to form a compact structure that occupies a small space. This design not only facilitates installation and maintenance, but also enables efficient gas collection and discharge in a limited space.
[0026] Specifically, a group of first exhaust holes 6 are formed on the upper plate of each group of corrugated cores 2. The upper end of the first exhaust pipe 3 penetrates and fits into the first exhaust hole 6 and is sealingly connected to the first exhaust hole 6 and the surrounding upper plate of the corrugated core 2 by welding. A plurality of groups of second exhaust holes 7 are circumferentially and equidistantly formed on the upper plate of each group of corrugated cores 2 around the first exhaust hole 6. A group of gas caps 8 are welded to the upper plate of each group of corrugated cores 2. The gas cap 8 is designed to have an internal chamber to form a collection area. The gas cap 8 can cover the first exhaust hole 6 and the second exhaust hole 7. The first exhaust hole 6 is a through hole with a diameter of 50 mm, and the second exhaust hole 7 is a through hole with a diameter of 8-12 mm.
[0027] The gas enters through the plurality of groups of second exhaust holes 7 evenly distributed around the upper plate of the corrugated core 2. The gas entering the upper plate of the corrugated core 2 will then accumulate in the internal chamber of the gas cap 8 welded thereto. The design of the gas cap 8 enables it to cover the first exhaust hole 6 and the second exhaust hole 7, forming a relatively closed gas collection area. In the gas cap 8, the gas further accumulates and is guided by the first exhaust hole 6 to enter the first exhaust pipe 3. The first exhaust pipe 3 and the first exhaust hole 6 are sealingly connected by welding to ensure that the gas does not leak. The gas is transported in the first exhaust pipe 3 and finally converges into the gas collecting box 4 and is discharged to the external environment through the second exhaust pipe 5.
[0028] Due to the smaller diameter of the second exhaust holes 7, 8-12 mm, they can serve as channels for the initial dispersion of the gas, and through multiple groups of second exhaust holes 7, the gas can have more channels to flow out of the corrugated core 2, which is equivalent to increasing the gas outflow area, thereby increasing the gas flow rate and discharge capacity. Since the gas can flow out more uniformly and has more outflow channels, the entire discharge process will be more efficient, which not only reduces the discharge time but also improves the discharge efficiency, allowing more gas to be discharged in a shorter time. Since the first exhaust hole 6 has a larger diameter, 50 mm, it can serve as the main channel for gas collection and efficient discharge, playing a major role in large gas quantities or when rapid exhaust is required.
[0029] Wherein: the first exhaust pipe 3 includes a first pipe body 9 and a second pipe body 10, the first pipe body 9 is a steel wire hose, and each end of the first pipe body 9 is equipped with a group of second pipe bodies 10, one group of second pipe bodies 10 penetrates the upper plate of the corrugated core 2, and the other group of second pipe bodies 10 penetrates the lower plate of the corrugated core 2 and the cabinet bottom plate 1.
[0030] The gas is transmitted in the first pipe body 9, and the second pipe bodies 10 connected at both ends of the first pipe body 9, one group of second pipe bodies 10 penetrates the upper plate of the corrugated core 2 and is connected to the first exhaust hole 6, and the other group of second pipe bodies 10 penetrates the lower plate of the corrugated core 2 and the cabinet bottom plate 1, discharging the gas to the external environment,
[0031] The first pipe body 9 is a steel wire hose, which contains a steel wire braid or spiral steel wire inside, which allows the hose to maintain a certain shape stability when subjected to external forces, while also being able to bend to a certain extent. During installation, the first pipe body 9 can be bent and adjusted according to actual needs to adapt to different installation space and angle requirements. This bending performance not only facilitates installation and debugging, but also improves the flexibility and adaptability of the entire exhaust system.
[0032] Working principle: the gas enters through the multiple groups of second exhaust holes 7 evenly distributed around the upper plate of the corrugated core 2, the gas entering the upper plate of the corrugated core 2 will then accumulate in the internal chamber of the gas cap 8 welded thereon. The design of the gas cap 8 allows it to cover the first exhaust hole 6 and the second exhaust hole 7, forming a relatively closed gas collection area. Inside the gas cap 8, the gas further accumulates and is guided by the first exhaust hole 6 to enter the first exhaust pipe 3, allowing the gas to be transmitted in the first pipe body 9, and the second pipe bodies 10 connected at both ends of the first pipe body 9, one group of second pipe bodies 10 penetrates the upper plate of the corrugated core 2 and is connected to the first exhaust hole 6, and the other group of second pipe bodies 10 penetrates the lower plate of the corrugated core 2 and the cabinet bottom plate 1, the gas finally collects in the gas collection box 4 and is discharged to the external environment through the second exhaust pipe 5.
[0033] Those not described in detail in the specification belong to the prior art known to those skilled in the art.
[0034] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
