Fig. 1 shows a structure of an integrated floating tile oil receiver structure in an embodiment of the present invention. For the purpose of illustration, the drawings show only the structures associated with embodiments of the invention.

Referring to fig. 1, an integrated floating tile oil-supply head structure 10 according to a preferred embodiment of the present invention is applied to a cross-flow turbine. The integrated floating pad oil-supply head structure 10 comprises a front oil tank 100, a floating pad 200, a rotating sleeve 300, an outer pipe 400, an operation oil pipe 500 and a feedback rod 600.

The front oil tank 100 has a low pressure oil inlet 110. The front oil tank 100 is connected to a low-pressure oil source through a low-pressure oil inlet 110 to provide stable and reliable low-pressure oil for the operation of the cross-flow turbine.

Referring also to fig. 2, one end of the floating shoe 200 is hermetically and rigidly connected to the front oil tank 100. The floating pad 200 is formed with a first high pressure passage 210, a second high pressure passage 220, an oil discharge passage 230, and an oil leakage passage 240 penetrating the side wall of the floating pad 200. The floating pad 200 is rigidly connected to the front fuel tank 100 to improve the structural stability of the floating pad 200.

One end of the rotating sleeve 300 is rotatably inserted into the floating tile 200 and is in sealing contact with the inner wall of the floating tile 200. One end of the rotary sleeve 300 is rotatably connected to the front oil tank 100. The inner wall of the rotating sleeve 300 is opened with a first oil passing hole 310 communicated with the first high pressure passage 210 and a second oil passing hole 320 communicated with the second high pressure passage 220. The first oil passing hole 310 and the second oil passing hole 320 are through holes, and the first oil passing hole 310 and the second oil passing hole 320 are always in communication with the first high pressure passage 210 and the second high pressure passage 220, respectively, no matter how the rotating sleeve 300 rotates in the floating pad 200.

One end of the outer tube 400 is sealed and rigidly connected to the end of the rotating sleeve 300 away from the front oil tank 100, and the other end is used for rigidly connecting to the main shaft 20 in the cross flow turbine. Thus, the rotary sleeve 300 is rigidly connected to the main shaft 20 through the outer tube 400 to improve stability of the rotary sleeve 300 when rotating in the floating shoe 200.

The operation oil pipe 500 is inserted into the rotary sleeve 300 and the outer pipe 400. The end of one end of the operation oil pipe 500 is in sealing engagement with the inner wall of the rotary sleeve 300 in the circumferential direction, and the other end is for sealing and rigid connection with the main shaft 20. A first high-pressure oil chamber 710 communicating with the first oil passing hole 310 is formed between the outer wall of the operation oil pipe 500 and the inner walls of the rotary sleeve 300 and the outer pipe 400. Specifically, the rotating sleeve 300, the outer tube 400 and the operating oil tube 500 are coaxially arranged and assembled with the main shaft 20 to form a rigid whole body, which can rotate synchronously.

The feedback rod 600 is inserted into the operation oil pipe 500 and spaced apart from the inner wall of the operation oil pipe 500 to form a second high-pressure oil chamber 720 communicating with the second oil passing hole 320. One end of the feedback rod 600 is hermetically inserted into the front oil tank 100, and the other end is installed on the main shaft 20. An oil passage 610 communicating the front oil tank 100 and a pressure maintaining chamber of a runner in the cross flow turbine is formed inside the feedback rod 600. Therefore, the feedback rod 600 connects the low-pressure oil in the front oil tank 100 into the pressure maintaining cavity in the hub body of the through-flow turbine runner through the oil passage 610, so that the sealing part of the runner is stressed in a balanced manner, and the reliability of rotary sealing is improved.

And two high-pressure oil sources are respectively connected into the first high-pressure oil chamber 710 and the second high-pressure oil chamber 720 through the first high-pressure channel 210 and the second high-pressure channel 220, and finally enter a rotating wheel access device in the through-flow turbine to be communicated with pressure chambers at two ends of a piston of the rotating wheel access device, and under the action of the high-pressure oil sources, the piston of the rotating wheel servomotor can do reciprocating motion back and forth in the horizontal direction, so that the rotating wheel blades can be controlled to rotate, and the joint motion of the load and the water head is realized.

The floating tile 200 is rigidly connected with the front oil tank 100, so that the stability of the floating tile 200 in the running process of the through-flow turbine can be improved. The rotating sleeve 300, the outer pipe 400, the operating oil pipe 500 and the main shaft 20 are assembled into a rigid whole in a rigid connection mode, so that all rotating parts in the integrated floating tile oil receiver structure 10 can rotate synchronously, the coaxiality is good, the swing amplitude of the integrated floating tile oil receiver structure 10 in the operation process can be reduced, the stability is high, the reduction of abrasion caused when the rotating sleeve 300 and the floating tile 200 move relatively is facilitated, and the service lives of the rotating sleeve 300 and the floating tile 200 can be prolonged. Therefore, the integrated floating tile oil-supply head structure 10 has high operation stability and high use reliability, and also has long service life.

In some embodiments, the floating shoe 200 includes a shoe body 250 and a sealing cover 260. The tile body 250 is a hollow structure with both ends open. The sealing cover 260 has a cover structure with two open ends. Both ends of the tile body 250 are sealed and rigidly connected to one ends of the front oil tank 100 and the sealing cover 260, respectively. The side wall of the shoe 250 is formed with a first high pressure passage 210, a second high pressure passage 220 and an oil drain passage 230 penetrating the side wall of the shoe 250. The side wall of the sealing cover 260 is provided with an oil leakage channel 240 which penetrates through the side wall of the sealing cover 260. The rotating sleeve 300 is rotatably disposed through the tile 250 and the sealing cover 260, and is respectively matched with the inner wall of the tile 250 and the opening edges at the two ends of the sealing cover 260 in a sealing manner. Specifically, the tile body 250 is of a unitary cast steel structure to improve the structural strength of the tile body 250. Of course, in other embodiments of the present invention, the tile body 250 may also be obtained by machining or the like.

The sealing cover 260 is used for collecting leakage oil leaked from the tile body 250 during the relative movement between the rotating sleeve 300 and the tile body 250 and discharging the leakage oil through the leakage oil channel 240; the shoe body 250 is used for connecting an external high-pressure oil source into the first high-pressure oil chamber 710 and the second high-pressure oil chamber 720, and simultaneously discharging part of leakage oil which does not enter the first high-pressure oil chamber 710 and the second high-pressure oil chamber 720 between the shoe body 250 and the rotating sleeve 300 by using the oil discharge passage 230. Therefore, the floating tile 200 is arranged into the tile body 250 and the sealing cover 260, so that the use effect of the integrated floating tile oil-supply head structure 10 is guaranteed, the processing difficulty of the floating tile 200 and the assembly difficulty of the integrated floating tile oil-supply head structure 10 are reduced, and the working condition of the cross-flow turbine in the combined operation can be stabilized.

Further, in some embodiments, the inner wall of the tile body 250 is formed with a tin-based babbitt metal layer (not shown). Specifically, a tin-based babbitt alloy layer is formed at the position where the inner wall of the tile body 250 contacts the rotating sleeve 300, and because the tin-based babbitt alloy layer has the anti-wear characteristic, a tin-based babbitt alloy layer is formed on the inner wall of the tile body 250, so that the service life of the tile body 250 can be further prolonged, and the service life of the integral floating tile oil receiver structure 10 can be prolonged.

Further, in some embodiments, the inner wall of the shoe body 250 is spaced apart to form a first high-pressure oil guide groove 211, a second high-pressure oil guide groove 221, and an oil discharge oil guide groove 231 disposed along the circumferential direction of the shoe body 250. Accordingly, the first high-pressure oil guide groove 211, the second high-pressure oil guide groove 221, and the oil drain oil guide groove 231 are all annular grooves. The outer surface of the shoe body 250 is provided with a first high pressure oil inlet 212, a second high pressure oil inlet 222 and an oil outlet 232. The first high pressure oil inlet hole 212 communicates with the first high pressure oil guide groove 211 to constitute a first high pressure passage 210. The second high pressure oil inlet hole 222 communicates with the second high pressure oil guide groove 221 to constitute the second high pressure passage 220. The oil discharge hole 232 communicates with the oil discharge guide groove 231 to constitute the oil discharge passage 230.

Therefore, when the rotary sleeve 300 rotates in the floating shoe 200, the first oil passing hole 310 may be communicated with different positions of the first high-pressure oil guide groove 211 to ensure that the passage between the first high-pressure oil inlet hole 212 and the first high-pressure oil chamber 710 is always in a conduction state, and the second oil passing hole 320 may be communicated with different positions of the second high-pressure oil guide groove 221 to ensure that the oil path between the second high-pressure oil inlet hole 222 and the second high-pressure oil chamber 720 is always in a conduction state, thereby ensuring the smoothness and reliability of oil inlet from the high-pressure oil source. In addition, the leakage oil between the rotating sleeve 300 and the shoe body 250 can be collected in the oil drainage and guiding groove 231 and then discharged from the oil drainage hole 232, and the leakage oil between the rotating sleeve 300 and the shoe body 250 can be smoothly discharged, so that the probability of oil leakage of the integrated floating shoe oil receiver structure 10 is further reduced.

An oil leakage cavity 241 is defined by the inner wall of the sealing cover 260 and the end surface of one end of the tile body 250 departing from the front oil tank 100. The outer surface of the sealing cover 260 is opened with an oil leakage hole 242. The oil leakage hole 242 communicates with the oil leakage chamber 241 to constitute the oil leakage passage 240. Wherein, the oil leakage cavity 241 is an annular inner cavity formed along the circumferential direction of the rotating sleeve 300.

When the rotating sleeve 300 rotates in the shoe body 250, part of the leakage oil between the rotating sleeve 300 and the shoe body 250 leaks from the end of the shoe body 250 far away from one end of the front oil tank 100, at this time, the leakage oil chamber can collect the part of the leakage oil and discharge the part of the leakage oil by using the oil leakage hole 242, so that the probability that the oil leaks from one end of the sealing cover 260 far away from the shoe body 250 is reduced, and the opening edge of one end of the sealing cover 260 far away from the shoe body 250 is in sealing fit with the rotating sleeve 300. The probability of leakage of the leakage oil in the oil leakage cavity 241 can be further reduced, and the probability of leakage of the integrated floating tile oil receiver structure 10 is further reduced.

Further, in some embodiments, the integrated floating pad oil-receiver structure 10 further includes an oil slinger 810. The oil slinger 810 is sleeved on the rotating sleeve 300 and is positioned in the oil leakage cavity 241. Specifically, the oil slinger 810 is positioned in the oil leakage cavity 241 near the position where the end of the sealing cover 260 far away from the tile body 250 is opened. When the rotating sleeve 300 rotates in the floating shoe 200, the oil slinger 810 rotates along with the rotation, so that leakage oil on the surface of the rotating sleeve 300 and at an opening of the sealing cover 260, which is far away from one end of the shoe body 250, is slinged, the probability that the leakage oil in the oil leakage cavity 241 leaks from an opening of the sealing cover 260, which is far away from one end of the outer sleeve, is further reduced, and the probability of oil leakage of the integrated floating shoe oil receiver structure 10 is further reduced.

Referring to fig. 3, in some embodiments, the rotating sleeve 300 includes a bottom plate 330, a side plate 340 disposed on the bottom plate 330 along a circumferential direction of the bottom plate 330, and a mounting plate 350 disposed on an end of the side plate 340 away from the bottom plate 330 along the circumferential direction of the bottom plate 330. The side of the bottom plate 330 facing away from the side plate 340 is rotatably connected to the front oil tank 100. The bottom plate 330 is formed with a mounting hole 331 communicating with the front oil tank 100. The mounting plate 350 is sealed and rigidly connected to one end of the outer tube 400. The side plate 340 is provided with a first oil passing hole 310 and a second oil passing hole 320. The end of one end of the operation oil pipe 500 is in sealing fit with the inner wall of the side plate 340 along the circumferential direction, and the sealing fit position is located between the first oil passing hole 310 and the second oil passing hole 320. The outer wall of the operation oil pipe 500 is spaced from the inner surface of the side plate 340 to form a first high-pressure oil chamber 710. An end of one end of the operation oil pipe 500 is spaced from an inner surface of the bottom plate 330 to communicate the second oil passing hole 320 and the second high-pressure oil chamber 720. Specifically, the bottom plate 330, the side plates 340 and the mounting plate 350 are integrally formed, so that the rotating sleeve 300 is an integrally formed structure formed by casting, machining, and the like. The rotary sleeve 300 is provided with the bottom plate 330, the side plate 340 and the mounting plate 350, so that the rotary sleeve 300 is a barrel-shaped structure with openings at both ends, and the mounting work between the rotary sleeve 300 and the front oil tank 100, the outer pipe 400, the operation oil pipe 500 and the feedback rod 600 is simpler.

Referring again to fig. 2, in some embodiments, the feedback rod 600 includes a rod 620, a tube joint 630, and a tube 640. One end of the rod 620 is hermetically inserted into the front oil tank 100, and the other end extends into the operation oil pipe 500 and is hermetically connected with the pipe 640 through a pipe joint 630. The end of the tube 640 remote from the coupling 630 is adapted to be mounted on the spindle 20 and is in communication with the pressure maintaining chamber of the wheel. The end face of the rod 620 connected to the pipe joint 630 is provided with a balance hole 621. The rod 620 is provided with a communication hole 622 for communicating the balance hole 621 and the front oil tank 100 at a position inside the front oil tank 100. The communication hole 622, the balance hole 621, the inner cavity of the pipe joint 630, and the inner cavity of the pipe body 640 are sequentially communicated to constitute an oil passage 610.

In the part processing, because the feedback rod 600 is a structure with a long length, the feedback rod 600 is not suitable for the whole processing due to the structural characteristics, and the feedback rod 600 is divided into the rod body 620, the pipe joint 630 and the pipe body 640 to be formed separately, so that the processing difficulty can be reduced, the processing precision can be improved, the material waste is less, and the processing cost is lower.

Referring again to fig. 1 and 2, in some embodiments, a support column 820 is disposed at the bottom of the front fuel tank 100. The supporting column 820 is used for being fixedly connected with the bulb head floor in the through-flow turbine. Therefore, the front oil tank 100 is fixed on the bulb head floor through the support column 820, so that the front oil tank 100 can keep a static state, the stability of the floating tile 200 rigidly connected with the front oil tank 100 is further improved, the stability of the oil receiver of the integrated floating tile 200 is higher, and the running stability and the use reliability of the through-flow turbine are further higher.

In some embodiments, the integrated floating pad oil-receiver structure 10 further includes a first high-pressure oil pipe 910 communicating with the first high-pressure passage 210, a second high-pressure oil pipe 920 communicating with the second high-pressure passage 220, an oil discharge pipe 930 communicating with the oil discharge passage 230, an oil leakage pipe 940 communicating with the oil leakage passage 240, and a low-pressure oil pipe 950 communicating with the low-pressure oil inlet 110. The first high pressure oil pipe 910, the second high pressure oil pipe 920 and the low pressure oil pipe 950 are all used for connecting the high level oil collecting tank. The oil drain pipe 930 and the oil drain pipe 940 are used for connecting the low-level oil collecting tank.

It should be noted that the number of the high-level oil collecting tanks and the low-level oil collecting tanks can be selected according to actual requirements, one high-level oil collecting tank which is simultaneously communicated with the first high-pressure oil pipe 910, the second high-pressure oil pipe 920 and the low-pressure oil pipe 950 can be provided, a plurality of high-level oil collecting tanks which are respectively communicated with the first high-pressure oil pipe 910, the second high-pressure oil pipe 920 and the low-pressure oil pipe 950 can also be provided,

because the high-level oil collecting tank is arranged at a higher position, even if sudden power failure or oil pump damage occurs, the high-level oil collecting tank can still provide low-pressure oil for a period of time into the front oil tank 100 by utilizing potential energy, and the high-level oil tank can also provide high-pressure oil for a period of time into the first high-pressure oil chamber 710 and the second high-pressure oil chamber 720, so that the equipment safety and the use reliability of the through-flow water turbine are improved. Because the low-level oil tank is placed at a lower position, oil in the oil discharge channel 230 and the oil leakage channel 240 flows out more easily, so that the integrated floating tile oil-supply head structure 10 is less prone to oil leakage, and the improvement of the stability of the tandem working condition of the through-flow turbine and the improvement of the safety of equipment are facilitated.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
