Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, specifically to a leak-proof storage tank for insulating liquid. Background Technology

[0002] Leak-proof insulating liquid storage tanks are key equipment used in industries such as power and chemical engineering to safely store insulating liquids such as transformer oil and synthetic esters. Their main function is to provide insulation and cooling media for electrical equipment (such as transformers) and ensure that these liquids are safely sealed and protected during storage.

[0003] In the existing technology, when the tank itself, which is the primary container, leaks, the leaked insulating liquid cannot be properly handled. Due to the lack of an effective secondary containment structure, the leaked insulating liquid will spread directly into the surrounding environment without any obstruction. At the same time, there is no reasonable guiding mechanism to control its diffusion direction and range. This will not only pollute the surrounding environment, but may also cause a series of safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a leak-proof storage tank for insulating liquid, so as to solve the problem mentioned in the background art of the inability to properly handle leaked insulating liquid.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an insulating liquid leak-proof storage tank, comprising a storage tank, a sealing cap installed on the upper end of the storage tank, a first drain port and a feed port installed on the storage tank, a protective outer tank installed on the storage tank, a first scale window installed on the protective outer tank, a guide port installed on the protective outer tank, a first bracket installed on the protective outer tank, a collection component installed on the guide port, and a cut-off component installed on the feed port. When the storage tank leaks, the collection component collects the insulating liquid that flows through the protective outer tank and the guide port. As the amount of insulating liquid collected inside the collection component increases, the cut-off component blocks the insulating liquid being transported to the storage tank through the feed port.

[0006] Based on the preferred embodiment of this technical solution, the protective outer tank has several flow guide grooves on the side near the storage tank, and the flow guide grooves are evenly distributed on the protective outer tank in a circumferential array.

[0007] Based on the preferred embodiment of this technical solution, the guide port is tapered with a wider top and a narrower bottom, and is installed on the lower end face of the protective outer tank.

[0008] Based on the preferred embodiment of this technical solution, the collection component includes a guide pipe installed on the guide port, a collection tank installed on the guide pipe, a second drain port installed on the collection tank, a closed cylinder installed on the collection tank, a connecting rod slidably connected to the closed cylinder, a warning light installed on the connecting rod, a float installed on the connecting rod, a rubber cover installed on the closed cylinder, a second scale window installed on the collection tank, and a second support installed between the collection tank and the first support. When insulating liquid enters the collection tank, the float will move upward by buoyancy.

[0009] Based on the preferred embodiment of this technical solution, the rubber cover is made of an elastic material, and the rubber cover has evenly spaced slits.

[0010] In the preferred embodiment of this technical solution, the closed cylinder has a limiting hole at the corresponding position of the connecting rod, and the connecting rod slides inside the limiting hole.

[0011] According to the preferred embodiment of this technical solution, the cutting component includes a guide plate installed on the feed inlet, a liquid inlet installed on the guide plate, a baffle slidably connected to the guide plate, and a spring installed between the baffle and the guide plate. When the spring is compressed, the baffle moves away from the axial position of the liquid inlet.

[0012] In the preferred embodiment of this technical solution, the guide plate has a groove at the corresponding position of the baffle, and the baffle slides inside the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up a protective outer tank and its internal guide channels and conical guide ports, this application upgrades the traditional passive leak prevention to active guidance and collection, effectively preventing the random spread of leaked liquid and greatly reducing the risk of environmental pollution and safety hazards.

[0014] 2. Through the mechanical linkage of the float, connecting rod and warning light, a conspicuous and intuitive visual alarm can be provided when a leak occurs, reminding staff to deal with it in a timely manner.

[0015] 3. When the liquid level inside the collection tank rises to the preset warning height, the baffle continues to rise, blocking the channel between the liquid inlet and the feed inlet, thereby mechanically blocking the main pipeline. This process is entirely driven by the buoyancy of the leaking liquid itself, without the need for electricity or manual intervention, thus achieving automatic safety isolation when a leak occurs.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 - Figure 6 This utility model provides an embodiment: an insulating liquid leak-proof storage tank, including a storage tank 21, a sealing cap 22 installed on the upper end of the storage tank 21, a first drain port 23 and a feed port 24 installed on the storage tank 21, and a protective outer tank 26 installed on the storage tank 21, a first scale window 27 installed on the protective outer tank 26, a guide port 28 installed on the protective outer tank 26, a first bracket 29 installed on the protective outer tank 26, a collection component installed on the guide port 28, and a cut-off component installed on the feed port 24. When the storage tank 21 leaks, the collection component collects the insulating liquid that flows through the protective outer tank 26 and the guide port 28. As the amount of insulating liquid collected inside the collection component increases, the cut-off component blocks the insulating liquid being transported to the storage tank 21 through the feed port 24. The protective outer tank 26 and the storage tank 21 form a double-layer enclosed structure, forming a complete protection system from primary leak prevention to secondary guidance and collection. Automatic detection and response to leaks are achieved through pure mechanical linkage.

[0020] Please see Figure 2 and Figure 3A further solution based on this embodiment is as follows: a plurality of guide channels are provided on the side of the protective outer tank 26 near the storage tank 21, and the guide channels are evenly distributed on the protective outer tank 26 in the form of a circumferential array. The guide channels can quickly guide the leaked liquid at any position to the guide port 28 at the bottom, avoid the liquid from stagnating in the interlayer, and improve the diversion efficiency.

[0021] Please see Figure 3 A further solution based on this embodiment is: the guide port 28 is a cone shape that is wider at the top and narrower at the bottom, and is installed on the lower end face of the protective outer tank 26. The cone-shaped structure is conducive to collecting liquids flowing from all directions, forming a funnel effect, ensuring that the leaked liquid completely enters the collection system, and preventing residues at the interface.

[0022] Please see Figure 1 , Figure 4 and Figure 5 A further solution based on this embodiment is as follows: The collection assembly includes a guide pipe 31 installed on the guide port 28, a collection tank 32 installed on the guide pipe 31, a second drain port 33 installed on the collection tank 32, a closed cylinder 34 installed on the collection tank 32, a connecting rod 35 slidably connected to the closed cylinder 34, a warning light 36 installed on the connecting rod 35, a float 37 installed on the connecting rod 35, a rubber cover 38 installed on the closed cylinder 34, a second scale window 39 installed on the collection tank 32, and a second bracket 310 installed between the collection tank 32 and the first bracket 29. When insulating liquid enters the collection tank 32, the float 37 will move upward by buoyancy. When the leaked liquid enters the collection tank 32, the float 37 rises with the liquid level and drives the warning light 36 to move upward through the connecting rod 35, so that it extends out of the closed cylinder 34 to form a conspicuous visual warning. At the same time, the rubber cover 38 can keep closed to avoid excessive exposure of the warning light 36, and also allow the connecting rod 35 to slide freely.

[0023] Please see Figure 5 A further solution based on this embodiment is as follows: the rubber cover 38 is made of elastic material, and the rubber cover 38 has evenly spaced gaps. The gaps remain closed in the natural state to ensure sealing and dust prevention. When the connecting rod 35 moves up and down, it can be elastically deformed, which not only does not affect the movement of the rod, but also prevents external impurities from entering the closed cylinder 34, and can block part of the light of the warning light 36.

[0024] Please see Figure 5 A further solution based on this embodiment is: the closed cylinder 34 has a limiting hole at the corresponding position of the connecting rod 35, and the connecting rod 35 slides inside the limiting hole. The limiting hole provides precise guidance for the connecting rod 35, ensuring that it can only move vertically, preventing skew and jamming, and ensuring the reliability of the float 37's action.

[0025] Please see Figure 1 and Figure 6 A further solution based on this embodiment is as follows: the cutting component includes a guide plate 41 installed on the feed inlet 24, a liquid inlet 42 installed on the guide plate 41, a baffle 43 slidably connected to the guide plate 41, and a spring 44 installed between the baffle 43 and the guide plate 41. When the spring 44 is compressed, the baffle 43 moves away from the axial position of the liquid inlet 42. When the liquid level in the collection tank 32 reaches a preset height, the float 37 pushes the connecting rod 35 to continue moving upward. Through the mechanical linkage mechanism, the elastic force of the spring 44 is overcome, and the baffle 43 is driven to slide to the position of closing the liquid inlet 42, thereby realizing automatic flow interruption.

[0026] Please see Figure 6 A further solution based on this embodiment is: the guide plate 41 has a groove at the corresponding position of the baffle 43, and the baffle 43 slides inside the groove. The groove structure provides a stable movement trajectory for the baffle 43, ensuring that it can be accurately aligned with the liquid inlet 42 to achieve complete sealing.

[0027] Working principle: When the storage tank 21, which serves as the primary container, leaks, the insulating liquid enters the space between the storage tank 21 and the protective outer tank 26. The guide channel on the inner wall of the protective outer tank 26 guides the leaking liquid in an orderly manner to the conical guide port 28 at the bottom, and then into the collection tank 32 through the guide pipe 31. As the liquid level in the collection tank 32 rises, the float 37, under the action of buoyancy, moves the warning light 36 upward through the connecting rod 35, causing it to extend out of the closed cylinder 34 to provide a clear visual alarm. When the leak continues and the liquid level reaches the preset danger height, the continued rise of the float 37 and the connecting rod 35 will trigger the cut-off component through mechanical linkage, causing the baffle 43 to slide against the resistance of the spring 44, closing the liquid inlet 42 at the feed port 24, and automatically stopping the continued delivery of insulating liquid to the storage tank 21, thus forming a complete protection process from leak detection and warning to automatic cut-off.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
