Description

Technical Field

[0001] The utility model relates to the technical field of perfusion structures, in particular to a pressure-maintaining perfusion device. Background Art

[0002] Figure 1 The diagram below shows a traditional ship cable penetration, a common method currently used to seal cable entryways. The entire cable penetration consists of a cable frame ③ with an opening, a filling hole ①, and a vent hole ②, a plugging material ④, and a filler ⑤. The construction process is as follows: First, holes are drilled in the appropriate shipboard steel siding ⑥. The cable frame ③ is then installed and welded. After all the cables ⑦ to be laid are passed through the cable frame ③, expandable plugging material ④ is used to seal the cables ⑦ at both ends of the cable frame ③ and then expand them with expansion fluid. This expansion creates a hollow cavity, which is then filled with cable sealing filler ⑤. Once the filler solidifies, the entire cable penetration system serves as a fireproof or watertight barrier between the ship's compartments.

[0003] But if Figure 1 As shown, due to the limited space inside ships, the interweaving of various water, air, gas, and electrical pipelines, and the limited deck height, cable penetrations are usually installed close to the upper deck. During the cable sealing filler pouring process, due to the limited operating space, pouring is often not possible. The cable sealing filler can only be scooped out from a container for pouring. On the one hand, the pouring efficiency is low; on the other hand, due to the small size of the pouring hole, the pouring process is prone to spillage, resulting in filler waste and making on-site cleaning more difficult.

[0027] like Figure 2 As shown, a pressure-maintaining pouring device includes a storage box 1, which has a receiving cavity for storing the material to be poured;

[0028] a delivery pipe 2, one end of which is connected to the storage tank 1 and the other end of which is connected to the outside;

[0029] a pressurizing member 3 , which is in communication with the storage box 1 , and is used to pressurize the storage box 1 by injecting gas into the storage box 1 , so that the material to be poured in the storage box 1 is transported to the outside through the delivery pipe 2 ;

[0030] A residual pressure relief pipe 4 is provided on the storage tank 1. The residual pressure relief pipe 4 is connected to the outside and is used to discharge the material to be poured and / or the cleaning liquid in the storage tank 1. A residual pressure relief valve 41 is provided on the residual pressure relief pipe 4. The residual pressure relief valve 41 is used to adjust the residual pressure of the storage tank 1.

[0031] The pressure-maintaining pouring device provided by this solution is particularly suitable for pouring cable sealing fillers. Of course, in other embodiments, the pressure-maintaining pouring device can also be used for pouring other materials, particularly liquid materials.

[0032] The pressure-maintaining filling device includes a storage box 1. The cable sealing filler to be filled is stored in the accommodating cavity of the storage box 1. When the storage box 1 is in a sealed state, the pressure-increasing member 3 connected to the air filling port 18 of the storage box 1 presses air into the pressure-maintaining filling device to increase the pressure. Since a soft conveying pipe 2 is provided at the discharge end of the storage box 1, and the diameter of the end of the conveying pipe 2 is usually less than or equal to the diameter of the filling hole of the cable penetration part, the cable sealing filler can be injected into the cavity of the cable penetration part after the end of the soft conveying pipe 2 is inserted into the filling hole. In order to avoid excessive pressure inside the storage box 1, this embodiment is also provided with a residual discharge pipe 4. The residual pressure release valve 41 of the residual discharge pipe 4 can release some gas inside the storage box 1, so that the rest of the gas inside the storage box 1 remains stable, which can just achieve the discharge of the cable sealing filler.

[0033] After a single cable penetration is filled, the delivery pipe 2 is removed to allow the next penetration to be filled. If the air pressure is insufficient, the pressurizing member 3 can be used to replenish it at any time. After all the cable sealing fillers required for the cable penetrations are filled, tap water or recycled water can be injected into the air filling port 18, and then air can be pressed in to circulate clean water inside the device, including cleaning the hose.

[0034] Furthermore, a flow regulating valve 21 is provided on the delivery pipe 2 , and the flow regulating valve 21 is used to adjust the discharge rate and discharge volume of the material to be poured in the delivery pipe 2 .

[0035] In order to control the pumping amount of the cable sealing filler at the delivery pipe 2, a flow regulating valve 21 is also provided on the delivery pipe 2. Usually, the flow regulating valve 21 is set at a position close to the end of the delivery pipe 2. In the early stage of perfusion, the flow regulating valve 21 can be adjusted to make the amount of filler discharged larger; in the late stage of perfusion (that is, when the filler is about to be filled), the flow regulating valve 21 can be adjusted to make the amount of filler discharged smaller to avoid overflow.

[0036] Furthermore, the storage tank 1 is provided with a pressure gauge 11, which is connected to the storage tank 1 to obtain the internal pressure value. In this embodiment, the pressure gauge 11 is provided to obtain real-time pressure information inside the storage tank 1. When the pressure inside the device is between 0.5 and 1 bar, the pressurizing element 3 can stop pressurizing. During the pressurized filling process, if the air pressure inside the storage tank 1 drops too much, the pressurizing element 3 can be activated at any time to increase the pressure inside the device to 0.5-1 bar.

[0037] The calculation basis of the above-mentioned 0.5-1bar injection pressure is: the density of the injected cable sealing filler is 1.5±0.2g / cm3, the distance between the pressure-maintaining injection device and the injection hole is about 3m, and according to the formula P=ρgh, converted to the international unit system, the pressure P can be calculated as P=1.5×103×9.8×3×

[0038] 10 -6 =0.0441

[0039] Mpa, which is about 0.45 bar. Taking into account the bending of the pipeline, the flow resistance of the filler liquid and the pressure drop in the device during the injection process, increasing the initial injection pressure to 1 bar can meet the injection requirements.

[0040] Furthermore, a valve 12 is provided at the connection point between the storage box 1 and the delivery pipe 2 to control the discharge of the material to be injected. To prevent excessive outflow of the cable sealing filler in the storage box 1 after pressurization, a valve 12 is provided at the connection point between the storage box 1 and the delivery pipe 2. After pressurization, the valve 12 is slowly opened, allowing the cable sealing filler to flow into the delivery pipe 2 under the air pressure within the storage box 1, and then flow to the injection hole of the cable penetration piece for injection.

[0041] Furthermore, the storage box 1 is provided with a feeding port 13, with a removable feeding port cover 14 at the feeding port 13. After the cable sealing filler in the storage box 1 has been partially poured out, additional cable sealing filler can be added at the feeding port 13, ensuring that the pressure-maintaining pouring device of this solution can continuously pour the cable sealing filler. The feeding port 13 is generally located at the top of the storage box 1. Specifically, the feeding port cover 14 is opened, and a certain amount of powder and auxiliary liquid are added in proportion. After being uniformly stirred by the stirrer 5, the cable sealing filler is obtained and is ready for pouring.

[0042] Furthermore, the apparatus further includes a stirrer 5, which is used to extend from the feeding port 13 into the accommodating cavity to stir the material to be poured in the accommodating cavity. In order to ensure the sealing of the pressure-maintaining pouring device, the stirrer 5 is movable. When stirring is required, the user can hold the stirrer 5 or directly clamp the stirrer 5 at the feeding port 13, with the end of the stirrer extending into the accommodating cavity to fully stir the cable sealing filler. The stirrer 5 can be manual or electric, as long as it can achieve uniform stirring of the filler.

[0043] Furthermore, the storage box 1 is provided with a transparent observation window 15. In this embodiment, the storage box 1 is provided with a transparent observation window 15, through which the amount of cable sealing filler pumped out can be observed in real time. When the amount approaches the theoretical injection amount / pumped out amount, the valve body 12 is closed and the amount of cable sealing filler injected into the cable penetration is observed, and then whether to continue to replenish the filler is considered.

[0044] Furthermore, the storage box 1 is provided with scale lines 16 distributed along its height. These scale lines 16 are located on one side of the observation window 15, which is arranged along the height of the storage box 1. Without these scale lines 16, the injection / pumping amount of the cable sealant can only be estimated by visual inspection, which is not particularly accurate. To determine the specific injection / pumping amount of the cable sealant, scale lines 16 are provided on one side of the observation window 15. The user can read these scale lines 16 to obtain the specific injection / pumping amount of the cable sealant, thereby preventing the pumped cable sealant from deviating excessively from the theoretical pumping amount.

[0045] Furthermore, the storage box 1 is provided with an inspection hole, which is provided with a removable inspection hole cover 17. Since the internal structure of the pressure-maintaining grouting device may be damaged or malfunction after long-term use, in order to facilitate the user to check the internal condition of the device, the present solution can provide an inspection hole on the front of the storage box 1. When in use, the inspection hole cover 17 on the inspection hole is in a closed state to prevent leakage of the cable sealing filler.

[0046] Furthermore, the pressurizing member 3 is a compressed air pot or an air pump, which can continuously pump gas into the storage box 1 to cause the cable sealing filler to be discharged to the outside.

[0047] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
