In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.
[0033] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0034] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.
[0035] Referring to Figures 1-4 As shown, the embodiment of the present utility model provides a water pressure simulation device for an underwater pressure compensator, including a pressure compensator 1, a pressure detection element 2, a cover plate assembly 3, and an elastic element 4. The pressure compensator 1 has an oil filling cavity 11; the pressure detection element 2 is installed on the pressure compensator 1 to detect the oil pressure in the oil filling cavity 11; the cover plate assembly 3 is connected to the bottom of the pressure compensator 1; one end of the elastic element 4 is connected to the bottom of the oil filling cavity 11, and the other end extends out of the pressure compensator 1 and is connected to the cover plate assembly 3; when the elastic element 4 is compressed, the elastic force of the elastic element 4 acts on the oil in the oil filling cavity 11, increasing the oil pressure in the oil filling cavity 11.
[0036] When the oil filling amount in the oil filling cavity 11 increases, the oil filling cavity 11 compresses the elastic element 4, and the elastic element 4 reacts on the oil in the oil filling cavity 11, increasing the oil pressure in the oil filling cavity 11; or by externally compressing the elastic element 4, the elastic force of the elastic element 4 will also act on the oil in the oil filling cavity 11, increasing the oil pressure in the oil filling cavity 11. For every 1 bar increase in the oil pressure in the oil filling cavity 11, it is equivalent to a water depth of 10 meters. Therefore, the water depth can be obtained by detecting the oil pressure in the oil filling cavity 11 by the pressure detection element 2, achieving the purpose of simulating the environmental pressure at a certain underwater depth, and then by observing the change of the oil in the oil filling cavity 11, it can be judged whether the oil filling amount injected into the oil filling cavity 11 matches the water depth.
[0037] The water pressure simulation device for an underwater pressure compensator of the present application can be applied to a land environment to simulate the environmental pressure at a certain underwater depth on land, facilitating obtaining whether the oil filling amount for the pressure compensator 1 is appropriate.
[0038] It should be noted that the structure of the pressure compensator 1 of the present application and the principle of realizing pressure compensation are both prior arts, and the present application will not elaborate in detail. For example, the pressure compensator 1 also has an exhaust hole.
[0039] Referring to Figure 2 andFigure 4 As shown, in some embodiments, there is a connecting member 14 between the refueling chamber 11 of the pressure compensator 1 and the elastic element 4. The connecting member 14 can move up and down synchronously with the expansion and contraction of the elastic element 4. Figure 2 and Figure 4 In the figure, the elastic element 4 is in a compressed state, and the connecting member 14 abuts against the bottom of the pressure compensator 1 with the compression of the elastic element 4.
[0040] Referring to Figures 1-4 As shown, the bottom of the pressure compensator 1 has a bottom plate 12. A through hole 13 for the elastic element 4 to extend out is provided on the bottom plate 12. The through hole 13 penetrates the bottom plate 12 along the thickness direction of the bottom plate 12. The elastic element 4 is in clearance fit with the through hole 13. The through hole 13 facilitates the elastic element 4 to extend out of the pressure compensator 1, and the elastic element 4 is in clearance fit with the through hole 13, avoiding friction between the elastic element 4 and the hole wall of the through hole 13 during expansion and contraction, and causing wear to the elastic element 4. The side of the through hole 13 facing the cover plate assembly 3 is flared, and the weight of the pressure compensator 1 can be appropriately reduced through the flaring.
[0041] Referring to Figures 1-4 As shown, in order to facilitate the installation and disassembly of the cover plate assembly 3, the cover plate assembly 3 is detachably connected to the pressure compensator 1. For example, the cover plate assembly 3 and the pressure compensator 1 can be connected by bolts 34. A plurality of bolts 34 are arranged circumferentially along the bottom plate 12 of the pressure compensator 1. The bottom plate 12 of the pressure compensator 1 and the cover plate assembly 3 are fastened by the cooperation of the bolts 34 and nuts 35, improving the connection stability between the pressure compensator 1 and the cover plate assembly 3.
[0042] Referring to Figures 1-4 As shown, in some embodiments, the pressure detection element 2 is a pressure gauge, and the pressure gauge is installed on the top of the pressure compensator 1. The oil pressure value in the refueling chamber 11 can be intuitively read by using the pressure gauge. The elastic element 4 is an elastic component such as a spring or a spring sheet. Preferably, the elastic element 4 is a spring.
[0043] Referring to Figure 1 and Figure 2 As shown, in some embodiments, the cover plate assembly 3 includes a first cover plate 31. The first cover plate 31 is connected to the bottom of the pressure compensator 1. The elastic element 4 extends out of the pressure compensator 1 and is connected to the side of the first cover plate 31 facing the pressure compensator 1. The first cover plate 31 and the bottom plate 12 of the pressure compensator 1 can be connected by bolts 34. The elastic element 4 is carried and installed by the first cover plate 31. A groove 311 is provided on the side of the first cover plate 31 facing the pressure compensator 1. One end of the elastic element 4 extending out of the pressure compensator 1 is embedded in the groove 311. The elastic element 4 is radially limited by the groove 311, and can also play a guiding role in the expansion and contraction of the elastic element 4. When the elastic element 4 is a spring, the groove 311 is an annular groove.
[0044] After installing the elastic element 4 between the first cover plate 31 and the strengthening cavity, gradually inject hydraulic oil into the oil filling cavity 11 of the pressure compensator 1. As the oil filling amount continuously increases, the hydraulic oil in the oil filling cavity 11 will compress the elastic element 4, and the elastic force of the elastic element 4 increases and reacts on the hydraulic oil in the oil filling cavity 11, causing the hydraulic pressure in the oil filling cavity 11 to increase. Every 1 bar increase in pressure is equivalent to a water depth of 10 meters. Read the hydraulic pressure of the hydraulic oil in the oil filling cavity 11 through the pressure gauge to obtain the water depth corresponding to this hydraulic pressure, so as to simulate the environmental pressure under the set water depth. When the hydraulic pressure of the hydraulic oil in the oil filling cavity 11 reaches the set pressure, stop injecting hydraulic oil into the oil filling cavity 11, and observe the change of the hydraulic oil in the oil filling cavity 11 to judge whether the oil filling amount is appropriate. Due to the elastic force of the elastic element 4, the hydraulic oil in the oil filling cavity 11 is compressed. Intuitively observe the hydraulic oil in the oil filling cavity 11 after stopping oil filling and compare it with the amount of hydraulic oil injected into the oil filling cavity 11 to obtain the compression amount of the hydraulic oil in the oil filling cavity 11 under this simulated water depth. If the compression amount of the hydraulic oil matches the simulated water depth, the oil filling amount is appropriate; if the compression amount of the hydraulic oil does not match the simulated water depth, the oil filling amount is inappropriate.
[0045] Refer to Figure 3 and Figure 4 As shown, in some embodiments, the cover plate assembly 3 includes a second cover plate 32 and a sleeve 33. The second cover plate 32 is connected to the bottom of the pressure compensator 1, and the sleeve 33 is threadedly assembled in the second cover plate 32. The elastic element 4 extends out of the pressure compensator 1 and passes through the second cover plate 32 to be connected to the inner wall of the sleeve 33. The second cover plate 32 and the bottom plate 12 of the pressure compensator 1 are detachably connected by bolts 34. The sleeve 33 is provided with an external thread, and the second cover plate 32 is provided with an internal thread hole, and the sleeve 33 is threadedly assembled in the internal thread hole. The sleeve 33, the second cover plate 32, and the elastic element 4 are coaxially arranged. By screwing the sleeve 33, the sleeve 33 moves relative to the second cover plate 32. When the sleeve 33 moves towards the second cover plate 32, the elastic element 4 is compressed. In order to facilitate applying force to the sleeve 33, a force application hole 3322 is provided at one end of the sleeve 33 away from the second cover plate 32, and a force application rod can be inserted into the force application hole 3322.
[0046] First, inject a set amount of hydraulic fluid into the oil filling chamber 11 of the pressure compensator 1. Then, install the elastic element 4 and the cover plate assembly 3. Screw the sleeve 33, causing the sleeve 33 to gradually move towards the second cover plate 32. The sleeve 33 compresses the elastic element 4, increasing the elastic force of the elastic element 4, which acts on the hydraulic fluid in the oil filling chamber 11, increasing the hydraulic pressure in the oil filling chamber 11. For every 1 bar increase in pressure, it is equivalent to a water depth of 10 meters. Read the hydraulic pressure of the hydraulic fluid in the oil filling chamber 11 through the pressure gauge. When the pressure read by the pressure gauge reaches the set pressure value, stop screwing the sleeve 33 to obtain the water depth corresponding to the set hydraulic pressure, thereby simulating the ambient pressure at that water depth. Observe the change of the hydraulic fluid in the oil filling chamber 11 to determine whether the oil filling amount is appropriate. After stopping screwing the sleeve 33, visually observe the compression amount of the hydraulic fluid in the oil filling chamber 11. If the compression amount of the hydraulic fluid matches the simulated water depth, the oil filling amount is appropriate; if the compression amount of the hydraulic fluid does not match the simulated water depth, the oil filling amount is inappropriate.
[0047] In some embodiments, the sleeve 33 includes a large-diameter section 331 and a small-diameter section 332 arranged in sequence. The large-diameter section 331 is threadedly connected to the second cover plate 32. A step surface 3321 is formed at the connection between the large-diameter section 331 and the small-diameter section 332. The elastic element 4 is connected to the step surface 3321. The large-diameter section 331 and the small-diameter section 332 are coaxially arranged. The large-diameter section 331 is threadedly inserted into the second cover plate 32, and the small-diameter section 332 extends outside the second cover plate 32. The elastic element 4 is abutted against the step surface 3321 between the large-diameter section 331 and the small-diameter section 332 to improve the connection stability between the elastic element 4 and the sleeve 33. The force application hole 3322 is provided at one end of the small-diameter section 332 away from the large-diameter section 331.
[0048] It should be noted that since the ambient pressure of the water pressure simulation device of the present application cannot be changed, it is equivalent to the inability to balance the internal and external pressures of the pressure compensator 1. The pressure compensator 1 resists the internal pressure hard, and excessive pressure will cause the compensator housing to be unable to bear. Therefore, the present application is applicable to simulating a water depth of 50 meters and a pressure of 5 bar.
[0049] In summary, the embodiment of the present utility model provides a water pressure simulation device for an underwater pressure compensator. A cover plate assembly 3 is connected to the bottom of the pressure compensator 1, and an elastic element 4 is connected between the bottom of the fuel filling chamber 11 of the pressure compensator 1 and the cover plate assembly 3. When the fuel filling amount in the fuel filling chamber 11 increases, the fuel filling chamber 11 compresses the elastic element 4, and the elastic element 4 reacts on the oil in the fuel filling chamber 11, causing the oil pressure in the fuel filling chamber 11 to increase; or by externally compressing the elastic element 4, the elastic acting force of the elastic element 4 also acts on the oil in the fuel filling chamber 11, causing the oil pressure in the fuel filling chamber 11 to increase. For every 1 bar increase in the oil pressure in the fuel filling chamber 11, it is equivalent to a water depth of 10 meters. Therefore, the water depth can be obtained by detecting the oil pressure in the fuel filling chamber 11 through the pressure detection element 2, achieving the purpose of simulating the environmental pressure at a certain underwater depth. Furthermore, by observing the change of the oil in the fuel filling chamber 11, it can be determined whether the fuel filling amount injected into the fuel filling chamber 11 matches the water depth.
[0050] The water pressure simulation device for an underwater pressure compensator of the present application can be applied to a land environment to simulate the environmental pressure at a certain underwater depth on land, facilitating the determination of whether the fuel filling amount for the pressure compensator 1 is appropriate.
[0051] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present utility model.
