Description

Technical Field

[0001] This invention relates to the field of DC power transmission engineering technology, and in particular to an auxiliary installation and positioning device for a flexible DC converter valve module. Background Technology

[0002] Flexible DC converter valves are commonly used in onshore converter stations of offshore wind power flexible DC transmission projects. During the on-site installation of the converter valve module, the connection status of the water-cooled interface affects the sealing reliability of the cooling circuit, the connection status of the fiber optic interface affects the reliability of valve-controlled communication or status transmission, and the position of the converter valve module relative to the valve tower mounting position affects the subsequent clamping, support, and interface stress state. Therefore, before the converter valve module is finally clamped or fixed, it is usually necessary to confirm whether the water-cooled interface is reliably connected, whether the fiber optic interface is properly inserted, and whether the module body has reached the target installation position.

[0003] In existing installation or inspection methods, the above-mentioned conditions are usually confirmed through manual visual inspection, torque verification, marking line inspection, and subsequent water circuit tests. Although these methods can detect interface connection abnormalities or module installation abnormalities to a certain extent, premature tightening may still occur if the water cooling interface is not reliably sealed, the fiber optic interface is not inserted in place, or the converter valve module has not reached the target installation position.

[0004] If the converter valve module is finally tightened without fully confirming the above conditions, it may result in bias pressure on the water-cooled interface, abnormal stress on the seals, leakage at the interface, or improper insertion of the fiber optic connector, incomplete locking, or failure of the optical channel inspection. Therefore, it is necessary to provide an auxiliary installation and positioning device that can confirm the connection status of the water-cooled interface, the insertion status of the fiber optic interface, and the target position of the module before final tightening of the converter valve module, and reduce the risk of accidental tightening when the conditions are not met. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide an auxiliary installation and positioning device for a flexible DC converter valve module. This invention can reduce the risk of accidental tightening of the converter valve module when it is not properly installed.

[0006] This invention provides an auxiliary installation and positioning device for a flexible DC converter valve module, comprising: The clamping and positioning mechanism has a module clamping position for clamping the converter valve module to the valve tower mounting position, and a module free position for releasing the converter valve module; The interlocking control mechanism and the water-cooling interface on the valve tower side are located at the valve tower mounting position; The interlocking control mechanism includes a pressure response unit and a locking execution unit. The pressure response unit triggers an action based on the water pressure output between the module-side water-cooled interface and the valve tower-side water-cooled interface. The locking execution unit responds to the triggering action, allowing the clamping and positioning mechanism to switch from the module free position to the module clamping position.

[0007] Preferably, the converter valve module is further provided with a module-side fiber optic interface, and the valve tower mounting position is provided with a valve tower-side fiber optic interface that is connected to the module-side fiber optic interface. The interlocking control mechanism also includes an insertion depth response unit; The insertion depth response unit outputs an insertion-in-place action based on the insertion depth of the module-side fiber optic interface relative to the valve tower-side fiber optic interface. The locking execution unit responds to the triggering action and the insertion-in-place action, allowing the clamping and positioning mechanism to switch from the module free position to the module clamping position.

[0008] Preferably, the interlocking control mechanism further includes a position response unit; The position response unit outputs a position arrival action when the converter valve module reaches the target position; When the locking execution unit responds to the triggering action, the insertion action, and the positioning action, it allows the clamping and positioning mechanism to switch from the module free position to the module clamping position.

[0009] Preferably, the locking execution unit includes: A locking tongue restricts the clamping and positioning mechanism from switching to the module clamping position, and it is provided with multiple pin holes; A latch retraction member drives the latch to move in the direction of releasing the restriction; and Multiple pins are provided, each pin being configured to correspond to a response unit in the interlocking control mechanism. Each pin is inserted into the corresponding pin hole in the initial state and is disengaged from the mating pin hole when the corresponding response unit outputs an action.

[0010] Preferably, the pressure response unit includes: The hydraulic chamber is connected to the pipeline between the module-side water-cooling interface and the valve tower-side water-cooling interface; A pressure-response element is disposed in the hydraulic chamber, which generates displacement in response to the water pressure, and is engaged with a corresponding pin shaft.

[0011] Preferably, the insertion depth response unit includes a depth trigger located beside the insertion path of the valve tower-side fiber optic interface. When the module-side fiber optic interface is inserted into the valve tower-side fiber optic interface to the preset depth, the module-side fiber optic interface pushes the depth trigger. The depth trigger engages with a corresponding pin shaft, and when the depth trigger moves, it drives the pin shaft to disengage from the engaging pin hole.

[0012] Preferably, the position response unit includes a position trigger, which is disposed at the valve tower mounting position and is driven in cooperation with the corresponding pin shaft. When the converter valve module reaches the target position, the converter valve module pushes the position trigger to act.

[0013] Preferably, the clamping and positioning mechanism includes: The handle base is located on the valve tower mounting side and has a slot that engages with the locking tongue. When the module is in the free position, the locking tongue engages in the slot, and when the module is in the pressed position, the locking tongue disengages from the slot. Locking handle, connected to the handle base; and An eccentric clamping component is linked to the handle base and clamps the converter valve module when the clamping and positioning mechanism switches from the module free position to the module clamping position.

[0014] Preferably, the handle base is provided with a return push part, and the locking tongue is provided with a push-receiving part. When the clamping and positioning mechanism switches from the module clamping position to the module free position, the return push part abuts against the push-receiving part and pushes the locking tongue to move in the direction of being inserted into the slot.

[0015] Preferably, the valve tower-side water-cooling interface has a back-end water passage, which includes: The test medium input branch is connected to the water circuit between the module-side water-cooling interface and the valve tower-side water-cooling interface; The pressure lead-out branch is connected to the pressure response unit; and The main water-cooled branch is connected to the main water-cooled system of the valve tower via the valves in the valve tower water circuit.

[0016] In the aforementioned auxiliary installation and positioning device for the flexible DC converter valve module, the auxiliary installation and positioning module of this invention utilizes water pressure, fiber optic insertion depth, and the target position of the module to jointly determine the clamping permission. If any installation criterion is not met, the locking execution unit restricts the clamping and positioning mechanism from switching to the module clamping position, thereby reducing the risk of premature clamping when the water-cooled interface is not reliably sealed, the fiber optic interface is not fully inserted, or the converter valve module has not reached the target position.

[0025] Unless otherwise specified, all embodiments and optional embodiments of this application can be combined to form new technical solutions.

[0026] First, it should be noted that flexible DC converter valves are typically used in onshore converter stations within offshore wind power flexible DC transmission projects. During on-site installation of the converter valve module, not only is mechanical positioning and fixation of the module body necessary, but also the completion of water-cooling interfaces, fiber optic interfaces, and related electrical connections. After installation, on-site handover testing typically requires visual inspection, wiring inspection, optical channel inspection, water-cooling pipeline inspection, water circuit testing, leakage detection device inspection, and valve control-related tests to confirm the reliability of the main water pipes, interlayer water pipes, and module inlet / outlet water pipe connections in the converter valve equipment assembly; whether the water pipe joints are tight and leak-free; and whether the fiber optic cable connectors are correctly inserted and the locking clips are in place.

[0027] In current installation or inspection processes, the connection status of water-cooled interfaces, the insertion status of fiber optic interfaces, and the target position status of the module body are often confirmed through manual visual inspection, torque verification, marking line inspection, and subsequent water circuit tests. While these methods can detect interface connection abnormalities to some extent, their confirmation results usually lack a direct interlocking relationship with the final tightening action. In other words, before the water-cooled interface is reliably sealed, the fiber optic interface is properly inserted, or the converter valve module has reached the target position, the operator may still perform the final tightening action, resulting in biased interfaces, abnormal stress on the sealing ring, improper insertion of fiber optic connectors, misaligned module installation posture, or failure of subsequent handover tests.

[0028] In the aforementioned application scenarios, the connection status of the water-cooled interface is related to the sealing reliability of the cooling circuit, the connection status of the fiber optic interface is related to the reliability of valve-controlled communication or status transmission, and the position of the converter valve module relative to the valve tower mounting position is related to the subsequent clamping, support, and interface stress state. Based on this, this application provides an auxiliary installation and positioning device that allows installation results such as water pressure, fiber optic insertion depth, and module target position to be assessed before the clamping action, and allows the final clamping action to be performed only after the corresponding conditions are met, thereby reducing the risk of premature clamping without confirming the installation status.

[0029] like Figure 1 and Figures 7-9As shown, in some embodiments, the auxiliary installation and positioning device includes a clamping and positioning mechanism 10, an interlocking control mechanism, and a valve tower-side water-cooled interface 210. The converter valve module 100 is provided with a module-side water-cooled interface 110. The clamping and positioning mechanism 10 has a module clamping position for clamping the converter valve module 100 to the valve tower mounting position 200, and a module free position for releasing the converter valve module 100. The interlocking control mechanism and the valve tower-side water-cooled interface 210 are disposed at the valve tower mounting position 200. The interlocking control mechanism includes a pressure response unit 30 and a locking execution unit 40. The pressure response unit 30 triggers an action based on the water pressure output between the module-side water-cooled interface 110 and the valve tower-side water-cooled interface 210. The locking execution unit 40 responds to the triggering action, allowing the clamping and positioning mechanism 10 to switch from the module free position to the module clamping position.

[0030] Specifically, the auxiliary installation and positioning device can be arranged on the valve tower mounting position 200 side of the flexible DC converter valve, for on-site installation of the converter valve module 100, pre-commissioning test inspection, or maintenance reassembly process. The converter valve module 100 is provided with a module-side water-cooling interface 110, and the valve tower mounting position 200 is provided with a valve tower-side water-cooling interface 210. As the converter valve module 100 is pushed towards the valve tower mounting position 200, the module-side water-cooling interface 110 gradually connects with the valve tower-side water-cooling interface 210 and forms an interface section water passage.

[0031] Furthermore, the auxiliary installation and positioning device includes a clamping and positioning mechanism 10, an interlocking control mechanism, and a water-cooling interface 210 on the valve tower side. The clamping and positioning mechanism 10 is located on the valve tower mounting position 200 side and has a module free position and a module clamping position. In this application, the module free position and the module clamping position are both working states of the clamping and positioning mechanism 10, not two positions of the converter valve module 100 in space. When the clamping and positioning mechanism 10 is in the module free position, it releases the converter valve module 100, allowing the converter valve module 100 to be pushed into or out of the valve tower mounting position 200. When the clamping and positioning mechanism 10 is in the module clamping position, it clamps the converter valve module 100 to the valve tower mounting position 200, keeping the converter valve module 100 in the installed state relative to the valve tower mounting position 200.

[0032] Furthermore, the interlocking control mechanism is located at the valve tower mounting position 200, and includes a pressure response unit 30 and a locking execution unit 40. The pressure response unit 30 is associated with the water passage between the module-side water-cooled interface 110 and the valve tower-side water-cooled interface 210. When the water pressure in the interface section reaches a preset threshold, the pressure response unit 30 outputs a trigger action. After responding to this trigger action, the locking execution unit 40 releases or allows the release of its restriction on the clamping and positioning mechanism 10, enabling the operator to switch the clamping and positioning mechanism 10 from the module free position to the module clamping position.

[0033] Optionally, the water pressure can be the pressure formed by the test medium input after the module-side water-cooling interface 110 and the valve tower-side water-cooling interface 210 are connected. The preset threshold can be determined according to the interface seal specifications, the design pressure of the valve tower-side water-cooling interface 210, on-site pressure testing requirements, or construction process requirements.

[0034] In one specific implementation, if the module-side water-cooled interface 110 and the valve tower-side water-cooled interface 210 have not been reliably connected, the water circuit of the interface section cannot establish the predetermined pressure, the pressure response unit 30 does not output a trigger action, and the locking execution unit 40 does not allow the clamping positioning mechanism 10 to switch to the module clamping position, thereby reducing the risk of premature clamping when the water-cooled interface is not reliably sealed.

[0035] Continue reading Figure 1 , Figure 7 and Figure 9 As shown, in some embodiments, the converter valve module 100 is further provided with a module-side fiber optic interface 120, and the valve tower mounting position 200 is provided with a valve tower-side fiber optic interface 220 that interfaces with the module-side fiber optic interface 120; the interlocking control mechanism also includes an insertion depth response unit 50. The insertion depth response unit 50 outputs an insertion-in-place action based on the insertion depth of the module-side fiber optic interface 120 relative to the valve tower-side fiber optic interface 220, and the locking execution unit 40 responds to the trigger action and the insertion-in-place action, allowing the clamping and positioning mechanism 10 to switch from the module free position to the module clamping position.

[0036] Specifically, the converter valve module 100 is also provided with a module-side fiber optic interface 120, and the valve tower mounting position 200 is provided with a valve tower-side fiber optic interface 220. The valve tower-side fiber optic interface 220 is arranged correspondingly to the module-side fiber optic interface 120, and is used to connect with the module-side fiber optic interface 120 during the process of the converter valve module 100 being advanced to the valve tower mounting position 200.

[0037] Furthermore, in addition to the pressure response unit 30 and the locking execution unit 40, the interlocking control mechanism also includes an insertion depth response unit 50. The insertion depth response unit 50 outputs the insertion-in-place action based on the insertion depth of the module-side fiber optic interface 120 relative to the valve tower-side fiber optic interface 220. The insertion-in-place action can be a trigger movement, a rocker arm swing, a push rod displacement, a slider displacement, or other mechanical actions.

[0038] In one specific implementation, the trigger action output by the pressure response unit 30 and the insertion-in-place action output by the insertion depth response unit 50 can jointly participate in the determination, allowing the locking execution unit 40 to switch the clamping and positioning mechanism 10 from the module free position to the module clamping position after responding to the trigger action and the insertion-in-place action. Thus, the water-cooled interface docking state and the fiber optic interface insertion state jointly participate in the clamping permission determination; after the module-side fiber optic interface 120 is inserted to a preset depth relative to the valve tower-side fiber optic interface 220, the insertion depth response unit 50 outputs an insertion-in-place action, which, in conjunction with the trigger action output by the pressure response unit 30, allows the locking execution unit 40 to allow the clamping and positioning mechanism 10 to switch.

[0039] like Figure 1-2 As shown, in some embodiments, the interlocking control mechanism further includes a position response unit 60; the position response unit 60 outputs a position-in-place action when the converter valve module 100 reaches the target position; when the locking execution unit 40 responds to the trigger action, the insertion-in-place action and the position-in-place action, it allows the clamping positioning mechanism 10 to switch from the module free position to the module clamping position.

[0040] Specifically, the interlocking control mechanism also includes a position response unit 60. The position response unit 60 is disposed at the valve tower mounting position 200, or on a support structure fixed relative to the valve tower mounting position 200. The position response unit 60 is used to output a position-ready action when the converter valve module 100 reaches the target position.

[0041] Furthermore, the target position can be the final positioning position of the converter valve module 100 relative to the valve tower mounting position 200, or it can be the position corresponding to the installation reference surface, positioning block, mounting lug, or module frame of the converter valve module 100 when it reaches the predetermined position. The target position is also related to the predetermined docking of the module-side water cooling interface 110 and the valve tower-side water cooling interface 210, the predetermined insertion of the module-side fiber optic interface 120 and the valve tower-side fiber optic interface 220, and the positioning of the installation reference of the converter valve module 100.

[0042] In one specific implementation, water pressure, fiber optic insertion depth, and target position together constitute the mechanical interlocking permission conditions before clamping. If any criterion is not met, the locking execution unit 40 will not allow the clamping positioning mechanism 10 to switch from the module free position to the module clamping position. Only when the pressure response unit 30 outputs a trigger action, the insertion depth response unit 50 outputs an insertion-in-place action, and the position response unit 60 outputs a position-in-place action, will the locking execution unit 40 allow the clamping positioning mechanism 10 to switch to the module clamping position. Thus, the auxiliary installation and positioning device forms a mechanical interlocking logic, making the water-cooled interface sealing state, fiber optic interface insertion state, and module body target position state jointly participate in the clamping permission judgment.

[0043] Combination Figures 1-3 As shown, in some embodiments, the locking execution unit 40 includes a locking tongue 41, a locking tongue retraction member 42, and a plurality of pins 44. The locking tongue restricts the clamping and positioning mechanism to switch to the module clamping position, and the locking tongue is provided with a plurality of pin holes; the locking tongue retraction member drives the locking tongue to move in the direction of releasing the restriction; each pin is correspondingly set with a response unit in the interlocking control mechanism, and each pin is inserted into the corresponding pin hole in the initial state and disengages from the mating pin hole when the corresponding response unit outputs an action.

[0044] Specifically, the locking tongue 41 is slidably disposed on the valve tower mounting position 200 side. The locking tongue 41 has a snap-in position and a retracted position. When the locking tongue 41 is in the snap-in position, the locking tongue 41 restricts the clamping and positioning mechanism 10 from switching to the module clamping position; when the locking tongue 41 is in the retracted position, the locking tongue 41 releases the restriction on the clamping and positioning mechanism 10.

[0045] Optionally, the latch 41 may have three pin holes, each corresponding to a pin 44. The three pins 44 serve as a pressure criterion pin, an insertion depth criterion pin, and a position criterion pin, respectively. In the initial state, the three pins 44 are inserted into their corresponding pin holes, thereby collectively restricting the movement of the latch 41 under the action of the latch retraction member 42.

[0046] Furthermore, the latch retraction member 42 is used to drive the latch 41 to move in the direction of release. Exemplarily, the latch retraction member 42 can be a tension spring, torsion spring, elastic sheet, or other mechanical force source. For example, the latch retraction member 42 can be a tension spring, one end of which is connected to the latch 41, and the other end to the valve tower mounting position 200, giving the latch 41 a tendency to exit the restricted position.

[0047] In one specific embodiment, each pin 44 is correspondingly assigned to a response unit in the interlocking control mechanism. The pin 44 corresponding to the pressure response unit 30 disengages from its mating hole when the pressure response unit 30 outputs a trigger action; the pin 44 corresponding to the insertion depth response unit 50 disengages from its mating hole when the insertion depth response unit 50 outputs an insertion-in-place action; and the pin 44 corresponding to the position response unit 60 disengages from its mating hole when the position response unit 60 outputs a position-in-place action. When any one of the three pins 44 is still inserted into its corresponding hole, the latch 41 cannot move to the released position under the action of the latch retraction member 42; only after all three pins 44 have disengaged from their corresponding holes can the latch 41 move under the action of the latch retraction member 42, thereby releasing the restriction on the switching of the clamping and positioning mechanism 10 to the module clamping position.

[0048] Optionally, the locking tongue 41 can be a rod-shaped member, a plate-shaped slider, a strip-shaped slider, or other locking member capable of moving between an engaged position and a retracted position. The locking tongue 41 can slide within a guide seat 45, which is disposed on the valve tower mounting position 200, the valve tower frame, or a support member fixed relative to the valve tower mounting position 200. The guide seat 45 can be a guide groove, a sleeve with a guide hole, two opposing guide plates, or a sliding limiting structure formed by a base plate and side plates. The locking tongue 41 passes through the guide hole or is embedded in the guide groove and can reciprocate along the direction defined by the guide hole or guide groove. The guide seat 45 is used to limit the sliding direction of the locking tongue 41, enabling the locking tongue 41 to move stably between the engaged position and the retracted position. The pin 44 can be inserted into the pin hole in a direction perpendicular to the sliding direction of the locking tongue 41, or in a direction intersecting the sliding direction of the locking tongue 41. The pin hole can be a round hole, an oblong hole, a notched hole, or a limiting groove adapted to the pin 44. Multiple pins 44 can be arranged at intervals along the length of the latch 41, along the width of the latch 41, or around different sides of the latch 41.

[0049] Furthermore, the pin 44 can cooperate with the pin reset component 441. When the corresponding response unit outputs an action, the pin 44 is driven out of the pin hole; when the corresponding response unit resets, the response unit no longer applies a force to hold the pin 44 out of the hole. At this time, if the locking tongue 41 has been pushed back into the locked position and the insertion path of the pin hole and the pin 44 is realigned, the pin reset component 441 can push the pin 44 to move back toward the pin hole and insert it into the pin hole. The pin reset component 441 can be a compression spring, a tension spring, an elastic sheet, or other element that can provide a reset force. When all three pins 44 have exited their corresponding pin holes, the locking tongue 41 moves under the action of the locking tongue retraction component 42, causing the pin hole to be misaligned relative to the pin 44. If a certain installation criterion fluctuates subsequently, causing the corresponding pin 44 to have a reset tendency, the pin 44 can only abut against the solid section of the latch 41 and cannot be re-inserted into the corresponding pin hole. The solid section refers to the solid limiting part of the latch 41, excluding the pin hole, that does not form a space for the pin 44 to insert. Because the pin 44 cannot be re-inserted into the pin hole, it cannot re-establish a locking constraint on the latch 41, and the latch 41 will not be re-restricted to the locked position or experience reciprocating jamming due to the short-term reset tendency of a single response unit. Therefore, abnormal repeated actions of the latch 41 due to water pressure fluctuations, trigger springback, or slight positional changes after the restriction is lifted can be avoided.

[0050] like Figure 4As shown, in some embodiments, the pressure response unit 30 includes a hydraulic chamber 31 and a pressure response element 32. The hydraulic chamber 31 is connected to the interface section water passage formed between the module-side water-cooling interface 110 and the valve tower-side water-cooling interface 210. The pressure response element 32 is disposed within the hydraulic chamber 31 and displaces in response to the water pressure in the interface section water passage. The pressure response element 32 is driven by a corresponding pin 44. When the water pressure in the interface section reaches a preset threshold, the pressure response element 32 displaces, causing the pin 44 corresponding to the pressure response unit 30 to disengage from the mating pin hole.

[0051] Furthermore, the withdrawal of the pin 44 corresponding to the pressure response unit 30 only indicates that the water pressure criterion is met; if the insertion depth criterion pin or the position criterion pin has not withdrawn, the locking tongue 41 still cannot release the restriction on the clamping and positioning mechanism 10. For example, the pressure response element 32 can be a piston, diaphragm, bellows, plunger, pressure-bearing slider, pressure expansion bladder, or other pressure response element capable of generating mechanical displacement based on water pressure. The hydraulic chamber 31 may have a pressure inlet, which can be connected to the back end water passage of the valve tower-side water-cooling interface 210 via a pressure lead-out branch 72.

[0052] In one specific embodiment, the pressure responder 32 can be driven to engage with the corresponding pin 44 via a transmission component. The transmission component can be a push rod, wedge, inclined block, connecting rod, or other transmission structure capable of converting the displacement of the pressure responder 32 into the retraction action of the pin 44. For example, when the pressure responder 32 moves in a first direction, it pushes a lever to swing, and the other end of the lever drives the corresponding pin 44 to retract from the pin hole in a second direction. The first and second directions can intersect or be perpendicular. In another example, the pressure responder 32 can also be coaxially or abutting against the corresponding pin 44. When the pressure responder 32 undergoes linear displacement under water pressure, it directly pushes or pulls the corresponding pin 44 out of the pin hole without a separate transmission component.

[0053] Furthermore, the pressure response unit 30 may also include a pressure response reset member 34. The pressure response reset member 34 is used to drive the pressure response member 32 to reset after the water pressure in the interface section is released. The pressure response reset member 34 can be a spring, the springback structure of the elastic diaphragm itself, or the springback structure of the elastic diaphragm itself. The pressure response reset member 34 can cooperate with the pin reset member 441; specifically, after the water pressure in the interface section is released, the pressure response reset member 34 drives the pressure response member 32 back to its initial position, so that the pressure response member 32 or the transmission component no longer applies a force in the retraction direction to the corresponding pin 44; when the locking tongue 41 returns to the engaged position and the corresponding pin hole and the insertion path of the pin 44 are realigned, the pin reset member 441 pushes the pin 44 toward the corresponding pin hole, thereby causing the pin 44 to re-insert into the corresponding pin hole. Optionally, the pressure response unit 30 may also be set with a pressure holding criterion, that is, after the water pressure in the interface section reaches a preset threshold and is maintained for a preset time, the pressure response member 32 will drive the corresponding pin 44 out of the pin hole. Specifically, the buffer chamber can temporarily store the pressure of the test medium entering the hydraulic chamber 31, the damping orifice or throttling channel can limit the speed at which the test medium enters or exits the buffer chamber, and the time-delay piston or mechanical delay element can complete the predetermined stroke only after the pressure has been applied for a period of time. Therefore, when only a short-term pressure spike occurs in the interface section water passage, the pressure response element 32 will not immediately generate a displacement sufficient to retract the pin 44; only when the pressure in the interface section water passage continuously reaches the preset threshold will the pressure response element 32 complete the trigger stroke and drive the corresponding pin 44 out of the pin hole, thereby reducing false triggering caused by instantaneous pressure shocks.

[0054] like Figures 1-3 As shown, in some embodiments, the insertion depth response unit 50 includes a depth trigger 51. The depth trigger 51 is located beside the insertion path of the valve tower-side fiber optic interface 220. When the module-side fiber optic interface 120 is inserted into the valve tower-side fiber optic interface 220 to a preset depth, the module-side fiber optic interface 120 pushes the depth trigger 51 to actuate. The depth trigger 51 is in drive engagement with the corresponding pin 44, and when the depth trigger 51 actuates, it causes the pin 44 corresponding to the insertion depth response unit 50 to disengage from the engagement pin hole.

[0055] Specifically, the depth trigger 51 does not directly contact the fiber end face, nor does it extend into the optical coupling area. Preferably, the depth trigger 51 is pushed by the connector housing, tailstock, insertion sleeve, limiting shoulder, locking part, or other non-optical coupling parts of the module-side fiber optic interface 120. This allows for confirmation of the insertion depth of the module-side fiber optic interface 120 while minimizing the impact of the depth trigger 51 on the fiber end face, optical coupling area, or optical signal transmission performance.

[0056] In one specific embodiment, the depth trigger 51 can be a push rod, a lever, a roller contact, a plunger, a slider, or other triggering components that can be pushed by the module-side fiber optic interface 120 and output mechanical action. The depth trigger 51 can be disposed beside the housing of the valve tower-side fiber optic interface 220 and move in a direction intersecting the insertion direction of the module-side fiber optic interface 120. When the module-side fiber optic interface 120 is inserted to a preset depth, the limiting shoulder on its connector housing pushes the depth trigger 51, and the depth trigger 51 drives the corresponding pin 44 out of the pin hole through a connecting rod, lever, inclined block, or wedge. In another example, the depth trigger 51 can also directly abut or be fixedly connected to the corresponding pin 44. After being pushed by the module-side fiber optic interface 120, the depth trigger 51 directly pushes or pulls the corresponding pin 44 out of the pin hole without a separate connecting rod, lever, or fork.

[0057] Furthermore, the insertion depth response unit 50 may also include a trigger reset member 52. When the module-side fiber optic interface 120 is inserted to a preset depth, the module-side fiber optic interface 120 pushes the depth trigger member 51 to actuate, and the depth trigger member 51 drives the corresponding pin 44 out of the pin hole. When the module-side fiber optic interface 120 is out of the pin hole, or when the insertion depth of the module-side fiber optic interface 120 relative to the valve tower-side fiber optic interface 220 is insufficient, the module-side fiber optic interface 120 no longer applies a positioning triggering action to the depth trigger member 51, and the trigger reset member 52 drives the depth trigger member 51 back to its initial position, so that the depth trigger member 51 no longer applies a force in the retraction direction to the corresponding pin 44. At this time, if the locking tongue 41 has been pushed back to the locked position and the corresponding pin hole is re-aligned with the insertion path of the pin 44, the pin reset member 441 can push the pin 44 to re-insert into the corresponding pin hole. The trigger reset member 52 can be a compression spring, tension spring, torsion spring, or elastic sheet. Optionally, the preset depth can correspond to the fully inserted position between the module-side fiber optic interface 120 and the valve tower-side fiber optic interface 220, or it can correspond to the locking position of the fiber optic connector housing, the limiting shoulder position, or the insertion sleeve reaching a predetermined position.

[0058] like Figures 1-3 and Figure 6 As shown, in some embodiments, the position response unit 60 includes a position trigger 61. The position trigger 61 is disposed at the valve tower mounting position 200. Further, when the converter valve module 100 reaches the target position, the converter valve module 100 actuates the position trigger 61. The position trigger 61 is in drive engagement with the corresponding pin 44, and when the position trigger 61 actuates, it causes the pin 44 corresponding to the position response unit 60 to disengage from the engaging pin hole.

[0059] Specifically, the target position can be the final positioning position of the converter valve module 100 relative to the valve tower mounting position 200, or it can be the position corresponding to when the module-side water cooling interface 110 and the valve tower-side water cooling interface 210 complete the predetermined docking, the module-side fiber optic interface 120 and the valve tower-side fiber optic interface 220 complete the predetermined insertion, and the mounting reference surface of the converter valve module 100 reaches the predetermined position.

[0060] In one specific embodiment, the position trigger 61 can be a limit contact, push rod, roller contact, slider, elastic stop block, or other position triggering structure that can be pushed by the converter valve module 100 and output mechanical action. The position trigger 61 can be disposed on the valve tower mounting position 200. When the converter valve module 100 is advanced to the target position, the frame, positioning block, mounting ear plate, side wall, or preset trigger protrusion of the converter valve module 100 pushes the position trigger 61. After the position trigger 61 is actuated, it drives the corresponding pin 44 to exit the pin hole through a lever, connecting rod, wedge, or inclined plane transmission component. In another example, the position trigger 61 can also directly abut or be fixedly connected to the corresponding pin 44. After the position trigger 61 is pushed by the converter valve module 100, it directly pushes or pulls the corresponding pin 44 out of the pin hole without a separate transmission component.

[0061] Furthermore, the position response unit 60 may also include a position trigger reset member 62. When the converter valve module 100 reaches the target position, the converter valve module 100 pushes the position trigger member 61 to actuate, and the position trigger member 61 drives the corresponding pin 44 to exit the pin hole. When the converter valve module 100 exits the target position, or when the converter valve module 100 has not yet reached the target position, the converter valve module 100 no longer applies the position triggering action to the position trigger member 61, and the position trigger reset member 62 drives the position trigger member 61 back to the initial position, so that the position trigger member 61 no longer applies the force in the retraction direction to the corresponding pin 44. At this time, if the locking tongue 41 has been pushed back into the locked position and the corresponding pin hole and the insertion path of the pin 44 are realigned, the pin reset member 441 can push the pin 44 to re-insert into the corresponding pin hole. The position trigger reset member 62 can be a compression spring, tension spring, torsion spring, or elastic sheet. Through the position trigger reset member 62, the position response unit 60 can be restored to the initial state during maintenance disassembly or removal of the converter valve module 100.

[0062] like Figures 1-3 and Figure 8As shown, in some embodiments, the clamping and positioning mechanism 10 includes a handle base 11, a locking handle 12, and an eccentric clamping member 13. The handle base 11 is located on the valve tower mounting position 200 side and has a groove that mates with the locking tongue 41. When in the module free position, the locking tongue 41 is engaged in the groove; when in the module clamping position, the locking tongue 41 is disengaged from the groove. The locking handle 12 is connected to the handle base 11. The eccentric clamping member 13 is linked to the handle base 11 and clamps the converter valve module 100 when the clamping and positioning mechanism 10 switches from the module free position to the module clamping position.

[0063] Specifically, the handle base 11 is disposed on the side of the valve tower mounting position 200 and is rotatably disposed on the valve tower mounting position 200. Exemplarily, the valve tower mounting position 200 is fixed to a valve tower frame, a valve tower mounting beam, or a support member fixed relative to the valve tower mounting position 200. The handle base 11 is rotatable about a pivot axis. The locking handle 12 is connected to the handle base 11. When the operator pulls the locking handle 12, the locking handle 12 drives the handle base 11 to rotate synchronously.

[0064] Furthermore, the handle base 11 is provided with a slot that engages with the locking tongue 41. When the clamping and positioning mechanism 10 is in the module free position, the locking tongue 41 engages in the slot, restricting the handle base 11 from rotating toward the module clamping position. When the clamping and positioning mechanism 10 is in the module clamping position, the locking tongue 41 disengages from the slot, and the handle base 11 is no longer restricted by the locking tongue 41.

[0065] In one specific embodiment, the eccentric clamping member 13 is linked to the handle base 11. Exemplarily, the eccentric clamping member 13 can be an eccentric block, eccentric wheel, eccentric cam, eccentric clamping arm, or other eccentric clamping components that move with the handle base 11 and exert a clamping effect on the converter valve module 100. When the clamping positioning mechanism 10 is in the module free position, the eccentric clamping member 13 avoids the converter valve module 100. When the clamping positioning mechanism 10 switches from the module free position to the module clamping position, the handle base 11 drives the eccentric clamping member 13 to rotate, and the eccentric clamping member 13 gradually abuts against and clamps the converter valve module 100, so that the converter valve module 100 is clamped within the valve tower mounting position 200.

[0066] Optionally, the handle base 11 can be a disc-shaped rotating seat, a swing arm type base, or the rotating body of other eccentric clamping mechanisms. The slot can be a limiting notch, a stop groove, or other insertion groove adapted to the end of the locking tongue 41, formed on the outer periphery of the handle base 11. The locking handle 12 can be a straight handle, a bent handle, a lever-type handle, or a swing handle with a grip. The eccentric clamping member 13 can directly abut against the converter valve module 100, or indirectly clamp the converter valve module 100 through a pressure plate, clamping roller, elastic pad, or other structure.

[0067] Furthermore, the clamping and positioning mechanism 10 may also include a clamping position retaining structure. The clamping position retaining structure is used to restrict the handle base 11 from rotating in the reverse direction from the module clamping position to the module free position when the clamping and positioning mechanism 10 is in the module clamping position. The clamping position retaining structure may include an over-center retaining structure, an elastic positioning pin and positioning hole, a pawl and anti-reverse teeth, a limit pin and anti-reverse groove, etc.

[0068] For example, the over-center holding structure can be an eccentric clamping member 13. When the clamping and positioning mechanism 10 rotates to the module clamping position, the force line of the eccentric clamping member 13 passes through the center position of the rotating shaft, so that the reaction force of the converter valve module 100 on the eccentric clamping member 13 tends to keep the handle base 11 in the module clamping position, rather than pushing the handle base 11 back to the module free position.

[0069] For example, the resilient locating pin and locating hole may include a resilient locating pin disposed on the valve tower mounting position 200 and a locating hole disposed on the handle base 11; when the handle base 11 rotates to the module clamping position, the resilient locating pin is inserted into the locating hole under the action of elastic force to restrict the reverse rotation of the handle base 11. For example, the pawl and anti-reverse tooth may include a pawl disposed on the valve tower mounting position 200 and an anti-reverse tooth disposed on the handle base 11; when the handle base 11 rotates to the module clamping position, the pawl abuts against the anti-reverse surface of the anti-reverse tooth to prevent the handle base 11 from reversing in the module free position direction.

[0070] For example, the limit pin and anti-reverse groove may include a limit pin disposed on one of the handle base 11 or the valve tower mounting position 200, and an anti-reverse groove disposed on the other. When the handle base 11 reaches the module clamping position, the limit pin enters the anti-reverse end or limit section of the anti-reverse groove to restrict the handle base 11 from rotating in the reverse direction from the module clamping position to the module free position. It should be noted that the clamping position retaining structure is used to prevent loosening after clamping, while the locking tongue 41 and the pin 44 are mainly used to prevent accidental operation of the clamping positioning mechanism 10 when the installation criteria are not met; their functions are different.

[0071] like Figures 1-3 As shown, in some embodiments, the handle base is provided with a return push part 112 and the locking tongue is provided with a push-receiving part 411. When the clamping and positioning mechanism 10 switches from the module clamping position to the module free position, the return push part 112 abuts against the push-receiving part 411 and pushes the locking tongue 41 to move in the direction of engaging the slot.

[0072] Specifically, the return push part 112 is integrally formed or fixedly connected to the handle base 11, and rotates synchronously with the handle base 11 around the pivot. The push part 411 is provided at one end of the locking tongue 41 near the handle base 11.

[0073] In one specific embodiment, when the clamping and positioning mechanism 10 switches from the module clamping position to the module free position, the handle base 11 rotates in the opposite direction, and the return push part 112 rotates with the handle base 11 to abut against the push part 411, pushing the push part 411 and causing the locking tongue 41 to move in the direction of engaging the slot. After the locking tongue 41 moves to the engaging position, one end of the locking tongue 41 re-engages in the slot, and the pin hole on the locking tongue 41 is re-aligned with the insertion path of the corresponding pin shaft 44. At this time, the clamping and positioning mechanism 10 has returned from the module clamping position to the module free position, and the converter valve module 100 is in a released state. It can be withdrawn from the valve tower mounting position 200 as needed for maintenance or disassembly, or pushed back into the valve tower mounting position 200 during subsequent reinstallation. After each response unit is reset, the corresponding pin shaft 44 can be re-inserted into the pin hole under the action of the pin shaft reset part 441, thereby restoring the locking execution unit 40 to the initial locking state.

[0074] Optionally, the return-pushing part 112 can be a cam, boss, lever, or other follower protrusion located on the outer edge of the handle base 11. The pushed part 411 can be a pushed surface, roller, lug, or inclined block at the end of the latch 41. When the clamping and positioning mechanism 10 is in the module clamping position, the return-pushing part 112 can be in a clearance position and not in contact with the pushed part 411; during the process of the clamping and positioning mechanism 10 resetting from the module clamping position to the module free position, the return-pushing part 112 contacts the pushed part 411 again and pushes the latch 41. Thus, the interference of the return-pushing part 112 on the normal retraction action of the latch 41 can be reduced.

[0075] like Figure 1 and Figure 4 As shown, in some embodiments, the valve tower-side water-cooled interface 210 has a back-end water path. The back-end water path includes a test medium input branch 71, a pressure output branch 72, and a main water-cooling branch 73. The test medium input branch 71 communicates with the interface section water path between the module-side water-cooled interface 110 and the valve tower-side water-cooled interface 210. The test medium input branch 71 can be equipped with a test interface, which can be a quick-connect coupling, threaded coupling, plug-in coupling, pressure testing coupling with a check valve, or other couplings that facilitate temporary connection to an external pressure testing device. During installation or inspection, the test interface can be connected to a manual pressure pump, a portable pressure testing device, or a test medium input device to input the test medium into the interface section water path.

[0076] Furthermore, the pressure lead-out branch 72 is connected to the pressure response unit 30. Specifically, the pressure lead-out branch 72 can be connected to the hydraulic chamber 31 through a pressure-leading pipe, rigid pipe, flexible pipe, or valve block channel, so that the pressure in the interface section water circuit can be transmitted to the hydraulic chamber 31 and drive the pressure response unit 32 to generate displacement.

[0077] In one specific implementation, the main water-cooling branch 73 is connected to the main water-cooling system of the valve tower via the valve tower water circuit valve 731. During installation or pressure testing, the valve tower water circuit valve 731 can be closed, isolating the interface section water circuit from the main water-cooling system of the valve tower. At this time, the test medium input through the test medium input branch 71 mainly acts on the interface section water circuit between the module-side water-cooling interface 110 and the valve tower-side water-cooling interface 210, as well as the pressure lead-out branch 72, thereby facilitating local pressure testing and pressure criterion confirmation of the interface section water circuit. After the interface section water circuit is confirmed to meet the requirements and the module is tightened, the valve tower water circuit valve 731 can be opened to connect the main water-cooling branch 73 to the main water-cooling system of the valve tower.

[0078] Optionally, the back-end water circuit can be formed by a three-way valve block, a four-way valve block, an integrated water circuit block, a pipe fitting assembly, a machined channel at the back end of the valve tower-side water-cooling interface 210, or a combination of multiple pipe fittings and pipelines. The test medium input branch 71, pressure output branch 72, and main water-cooling branch 73 can be integrated into the same valve block, or they can be formed by combining external pipelines. The test medium input branch 71, pressure output branch 72, and main water-cooling branch 73 can share some pipelines, or they can be connected to different interfaces at the back end of the valve tower-side water-cooling interface 210. The valve 731 of the valve tower water circuit can be a manual valve, an electric valve, a ball valve, a needle valve, a gate valve, or other valves that can isolate or connect the interface section water circuit to the valve tower main water-cooling system.

[0079] Please see Figure 7 In one specific embodiment, the converter valve module 100 moves towards the valve tower mounting position 200 along a preset propulsion direction. Optionally, the auxiliary installation and positioning device may further include a load-bearing sliding mechanism 80, which carries the converter valve module 100 and guides it towards the valve tower mounting position 200. The load-bearing sliding mechanism 80 may include guide rails, rollers, and load-bearing brackets. During the propulsion process, the module-side water-cooling interface 110 gradually connects with the valve tower-side water-cooling interface 210, the module-side fiber optic interface 120 gradually inserts into the valve tower-side fiber optic interface 220, and the converter valve module 100 gradually approaches the target position.

[0080] Specifically, when the clamping and positioning mechanism 10 is in the module free position, the eccentric clamping member 13 avoids the converter valve module 100, allowing the converter valve module 100 to be pushed into or withdrawn from the valve tower mounting position 200. One end of the locking tongue 41 is engaged in the slot of the handle base 11, restricting the rotation of the handle base 11. The three pins 44 corresponding to the pressure response unit 30, the insertion depth response unit 50, and the position response unit 60 are respectively inserted into the three pin holes of the locking tongue 41, restricting the locking tongue 41 from exiting the slot under the action of the locking tongue retraction member 42. At this time, even if the operator moves the locking handle 12, because the locking tongue 41 is engaged in the slot, the handle base 11 cannot rotate toward the module clamping position, and the eccentric clamping member 13 cannot perform the final clamping action.

[0081] Furthermore, after the module-side water-cooling interface 110 and the valve tower-side water-cooling interface 210 form an interface section water circuit, the operator closes the valve tower water circuit valve 731 to isolate the interface section water circuit from the main water-cooling system of the valve tower, and inputs the test medium into the interface section water circuit through the test medium input branch 71. When the pressure of the interface section water circuit reaches the preset threshold, the pressure is transmitted to the hydraulic chamber 31 through the pressure lead-out branch 72, and the pressure response element 32 is displaced. This displacement is then caused by the transmission element to drive the pin 44 corresponding to the pressure response unit 30 out of the corresponding pin hole, or the pressure response element 32 can directly push or pull the corresponding pin 44 out of the corresponding pin hole. If there is a misalignment, seal ring damage, incomplete insertion, or poor sealing between the module-side water-cooling interface 110 and the valve tower-side water-cooling interface 210, the pressure of the interface section water circuit will not reach the preset threshold, or will not be maintained within the preset time. In this case, the pressure response element 32 will not generate sufficient displacement, the corresponding pin 44 will still be inserted into the pin hole, and the locking tongue 41 will not be able to exit the slot.

[0082] Furthermore, when the module-side fiber optic interface 120 is inserted to a preset depth relative to the valve tower-side fiber optic interface 220, the connector housing, tailstock, insertion sleeve, or limiting shoulder of the module-side fiber optic interface 120 pushes the depth trigger 51. After the depth trigger 51 is activated, it drives the pin 44 corresponding to the insertion depth response unit 50 to exit the corresponding pin hole through the corresponding transmission structure, or the depth trigger 51 directly pushes or pulls the corresponding pin 44 to exit the corresponding pin hole. If the module-side fiber optic interface 120 is not fully inserted, the depth trigger 51 does not activate or its activation stroke is insufficient, and the corresponding pin 44 remains inserted in the pin hole. At this time, even if the water pressure meets the requirements, the locking tongue 41 cannot exit the slot, and the clamping and positioning mechanism 10 cannot switch to the module clamping position.

[0083] When the converter valve module 100 reaches the target position, it pushes the position trigger 61. After the position trigger 61 is activated, it drives the pin 44 corresponding to the position response unit 60 to exit the corresponding pin hole through the corresponding transmission structure, or the position trigger 61 directly pushes or pulls the corresponding pin 44 to exit the corresponding pin hole. If the converter valve module 100 has not reached the target position, the position trigger 61 does not activate or its activation stroke is insufficient, and the corresponding pin 44 remains inserted in the pin hole. At this time, even if the water pressure and fiber optic insertion depth meet the requirements, the locking tongue 41 still cannot exit the slot, and the clamping and positioning mechanism 10 still cannot switch to the module clamping position.

[0084] Furthermore, when the three criteria of water pressure, fiber optic insertion depth, and target position are all met, all three pins 44 retract from their corresponding pin holes. The locking tongue 41 is no longer restricted by the pins 44 and moves to the retracted position under the action of the locking tongue retraction member 42, exiting the slot of the handle base 11. At this time, the locking execution unit 40 allows the clamping positioning mechanism 10 to switch from the module free position to the module clamping position. The operator pulls the locking handle 12, which drives the handle base 11 to rotate, and the handle base 11 drives the eccentric clamping member 13 to move. The eccentric clamping member 13 gradually abuts against the converter valve module 100 and applies clamping force, so that the converter valve module 100 is clamped to the valve tower mounting position 200. After the clamping positioning mechanism 10 switches to the module clamping position, the clamping position holding structure can prevent the handle base 11 from loosening in the opposite direction.

[0085] Furthermore, when maintenance or disassembly of the converter valve module 100 is required, the clamping position holding structure is first released. Then, the operator reverses the locking handle 12, causing the clamping positioning mechanism 10 to switch from the module clamping position to the module free position. When the handle base 11 rotates in the reverse direction, the return push part 112 abuts against the push part 411 and pushes the locking tongue 41 to move in the direction of engaging the slot. After the clamping positioning mechanism 10 returns to the module free position, the locking tongue 41 re-engages in the slot, and the pin hole and the insertion path of the corresponding pin shaft 44 are re-aligned. Subsequently, when the water circuit of the interface section is depressurized, the fiber optic interface 120 on the module side is withdrawn, or the converter valve module 100 leaves the target position, the pressure response unit 30, the insertion depth response unit 50, and the position response unit 60 are reset respectively. The corresponding pin shaft 44 is re-inserted into the pin hole under the action of the pin shaft reset part 441, and the locking execution unit 40 returns to the initial locking state.

[0086] The following provides further explanation of the process for preventing accidental clamping of the auxiliary installation and positioning device when the installation criteria are not met.

[0087] If the water pressure is insufficient, the pin 44 corresponding to the pressure response unit 30 will not exit the pin hole, the locking tongue 41 will not exit the slot, and the clamping and positioning mechanism 10 will not be able to switch from the module free position to the module clamping position. This reduces the likelihood of the water-cooled interface being prematurely clamped before it is reliably sealed, which could lead to abnormal stress or leakage at the interface.

[0088] If the fiber optic interface 120 on the module side is not inserted into the fiber optic interface 220 on the valve tower side to the preset depth, the pin 44 corresponding to the insertion depth response unit 50 will not retract from the pin hole, and the locking tongue 41 will not retract from the slot. This reduces the likelihood of fiber optic connections being abnormal, locking mechanisms failing to engage properly, or subsequent optical channel checks failing due to premature clamping before the fiber optic interface is fully inserted.

[0089] If the converter valve module 100 does not reach the target position, the pin 44 corresponding to the position response unit 60 will not exit the pin hole, and the locking tongue 41 will not exit the slot. This reduces the likelihood of module installation deviations, interface force misalignment, or subsequent mechanical connection abnormalities caused by premature clamping when the module is not in the intended installation position.

[0090] In summary, the auxiliary installation and positioning module of this application can jointly participate in the clamping permission judgment based on water pressure, fiber optic insertion depth, and module target position. If any installation criterion is not met, the locking execution unit 40 restricts the clamping positioning mechanism 10 from switching to the module clamping position, thereby reducing the risk of premature clamping when the water cooling interface is not reliably sealed, the fiber optic interface is not inserted in place, or the converter valve module 100 has not reached the target position.
