Through the setting of an automatic oil replenishment mechanism, when the motor main body needs to replenish lubricating oil, the automatic oil replenishment mechanism will automatically replenish lubricating oil into the motor main body without having to take the motor main body out of the deep sea. This can greatly improve work efficiency, significantly reduce the workload of the staff, and the staff only need to go to the deep sea to replace the oil storage barrel when the lubricating oil in the oil storage barrel is exhausted, which can greatly reduce the frequency and number of times of going to the deep sea to replenish lubricating oil for the motor main body.

Description

Technical Field

[0001] The present application relates to the field of submersible motors, and more specifically, to a deep-sea oil-immersed submersible motor. Background Art

[0002] Submersible motors have the advantages of small size, light weight, no need for water priming before starting, not being restricted by the suction lift, not requiring an additional pump house, being convenient for installation and use, reliable in performance, high in efficiency, low in price, and saving investment. They can be used as the power source for various underwater machinery, such as the driving motor for drills used in bridge and building exploration, and the power source for the propellers of various underwater research vessels.

[0003] The oil-immersed submersible motor is a type of submersible motor. The motor has an oil-filled and sealed structure, the inner cavity is filled with insulating lubricating oil, oil-resistant rubber "O" rings are installed at each mating surface of the stop ends, and a mechanical seal device is installed at the shaft extension end, which can not only prevent external moisture and dampness from entering the inner cavity of the motor but also prevent the leakage of the insulating lubricating oil inside the machine.

[0004] During the operation of the oil-immersed submersible motor, the lubricating oil inside it will be consumed. When the lubricating oil is consumed to a certain extent, it needs to be replenished. For the existing oil-immersed submersible motors, when they are put into use in the deep sea, if you want to replenish the lubricating oil, you need to take the motor out of the deep sea, then disassemble the machine, add oil, and then put it back into the deep sea after adding oil. The operation is not only difficult but also inefficient. Therefore, we propose a deep-sea oil-immersed submersible motor. Summary of the Invention

[0005] The purpose of this application is to design an oil-immersed submersible motor that can automatically replenish lubricating oil, so as to reduce the frequency and number of times for staff to go to the deep sea to replenish lubricating oil for the motor body. Compared with the prior art, a deep-sea type oil-immersed submersible motor is provided, including a protective chassis. A motor body is fixedly installed inside the protective chassis. A refueling pipe is provided on the motor body. An oil level sensor for detecting the remaining amount of lubricating oil in the machine body is provided inside the motor body. An automatic refueling mechanism is provided on the protective chassis. The automatic refueling mechanism includes an oil storage barrel located above the protective chassis. A pressure oil piston plate that is slidably and sealingly connected thereto is provided inside the oil storage barrel. Lubricating oil is filled below the pressure oil piston plate. An electric telescopic rod is fixedly installed on the inner wall of the top end of the oil storage barrel. The output end of the electric telescopic rod is fixedly connected to the pressure oil piston plate. The bottom end of the oil storage barrel is communicated with a refueling one-way valve. The bottom end of the refueling one-way valve is connected with a connecting sleeve that matches the refueling pipe. The connecting sleeve is threadedly and sealingly connected to the refueling pipe. The one-way conduction direction of the refueling one-way valve is from top to bottom. A protective cover is fixedly installed on the outer wall of the oil storage barrel. A self-replenishing intelligent controller is fixedly installed inside the protective cover. An oil quantity monitoring module and a refueling control module are provided in the self-replenishing intelligent controller. The oil level sensor is wirelessly signal-connected to the oil quantity monitoring module. The oil quantity monitoring module is electrically connected to the refueling control module. The refueling control module is electrically connected to the electric telescopic rod. When the motor body needs to replenish lubricating oil, the automatic refueling mechanism will automatically replenish lubricating oil into the motor body without having to take the motor body out of the deep sea, thereby greatly improving work efficiency and significantly reducing the workload of the staff.

[0006] Furthermore, a reminder switch is fixedly installed on the inner wall of the bottom end of the oil storage barrel. A rubber sealing sleeve that matches it is provided outside the reminder switch. The rubber sealing sleeve is made of oil-resistant rubber material. A replacement reminder module and a remote connection module based on Internet of Things technology are also provided in the self-replenishing intelligent controller. The reminder switch is electrically connected to the replacement reminder module. The replacement reminder module is electrically connected to the remote connection module. When the remaining lubricating oil in the oil storage barrel is running low, the remote connection module will send a reminder signal to the staff, prompting the staff to replace the oil storage barrel in time, thereby ensuring that the motor body can be effectively replenished when it lacks oil.

[0007] Furthermore, an automatic water-blocking plug is arranged in the oil filling pipe. The automatic water-blocking plug includes a fixed plug block that matches the oil filling pipe and is fixedly installed in the oil filling pipe. The top end of the fixed plug block is flush with the top end of the oil filling pipe. A oil guiding hole is formed in the middle of the fixed plug block. The oil guiding hole is arranged in a frustum shape with a smaller upper part and a larger lower part. A movable plug block that matches it is slidably and sealingly connected in the oil guiding hole. The automatic water-blocking plug further includes a support net installed in the oil filling pipe. The support net is located below the fixed plug block. A sealing guide cylinder is fixedly installed at the top end of the support net. A guide slide rod that is slidably and sealingly connected to it is penetrated through the outer wall at the top end of the sealing guide cylinder. The top end of the guide slide rod is fixedly connected to the movable plug block. A pair of resistance support elastic ropes are fixedly connected between the top end inner wall of the guide slide rod and the sealing guide cylinder, enabling the automatic water-blocking plug to play a sealing role on the premise of not affecting the replenishment of lubricating oil into the motor main body, preventing seawater from flowing into the motor main body through the oil filling pipe when replacing the oil storage barrel, and greatly improving the practicability.

[0008] Furthermore, a plurality of drain holes are formed in the outer wall at the top end of the connecting sleeve. The plurality of drain holes are evenly distributed in a ring shape, enabling the drain holes to be conducive to the discharge of seawater in the connecting sleeve, preventing seawater from entering the motor main body through the oil filling pipe when replenishing lubricating oil to the motor main body. An oil filling pipe is communicated with the outer wall of the oil storage barrel. A sealing cover that matches it is arranged at one end of the oil filling pipe, enabling the staff to recharge lubricating oil into the replaced oil storage barrel through the oil filling pipe after bringing the oil storage barrel back to the land, so that the oil storage barrel can be reused, improving the practicability.

[0009] Optionally, an enhanced water-blocking assembly is further arranged on the oil filling pipe. The enhanced water-blocking assembly includes an inner support cylinder fixedly installed on the inner wall of the oil filling pipe and an outer support cylinder fixedly installed on the outer wall of the oil filling pipe. A linkage movable block is slidably and sealingly connected in the inner support cylinder. A clamping rod block is fixedly connected to one end of the linkage movable block close to the sealing guide cylinder. A spring is fixedly connected to the other end of the linkage movable block. The spring is in a compressed state. A driving and adjusting magnet is fixedly installed in the outer support cylinder. The linkage movable block is made of metallic iron. The clamping rod block penetrates through the outer wall of the sealing guide cylinder and is slidably connected to it. The top end of the clamping rod block is flush with the bottom end of the guide slide rod. A magnetic isolation cover cylinder is sleeved on the outer wall of the outer support cylinder. The magnetic isolation cover cylinder is threadedly connected to the driving and adjusting magnet. The magnetic isolation cover cylinder is made of a magnetic isolation material, enabling the clamping rod block to clamp the guide slide rod through simple adjustment when replacing the oil storage barrel, so as to prevent the movable plug block from moving downward under the action of water pressure, and further preventing seawater from flowing into the motor main body through the oil filling pipe.

[0010] Optionally, a damage detection and repair promotion component is also provided inside the protective chassis. The damage detection and repair promotion component includes a water guide bottom plate fixedly installed on the inner wall of the bottom end of the protective chassis. The top end of the water guide bottom plate is fixedly connected with an adjustment cylinder. A trigger piston plate is slidably and sealingly connected inside the adjustment cylinder. A damage detection and driving agent is filled below the trigger piston plate. An alarm switch is fixedly installed on the inner wall of the top end of the adjustment cylinder. The alarm switch is wirelessly connected to the remote connection module. The water guide bottom plate is made of a water-absorbing material, and the damage detection and driving agent is made of a water-absorbing and expanding material. When the protective chassis is damaged, the damage detection and repair promotion component will detect this phenomenon and send an alarm to relevant staff through the remote connection module, prompting the staff to perform corresponding maintenance on the protective chassis in a timely manner, thereby greatly reducing the erosion of seawater on the main body of the motor.

[0011] Furthermore, a water guide rod is fixedly connected to the top end of the water guide bottom plate. Water guide ropes are fixedly connected to the outer walls on both the left and right sides of the water guide rod. The water guide rod and the water guide ropes are both made of water-absorbing materials, and the water guide rod and the water guide ropes are both embedded in the damage detection and driving agent. The water guide rod and the water guide ropes can accelerate the conduction of seawater into the damage detection and driving agent, thereby accelerating the expansion of the damage detection and driving agent, and further improving the response efficiency of the damage detection and repair promotion component.

[0012] Compared with the prior art, the advantages of this application are as follows:

[0013] (1) Through the setting of the automatic oil replenishment mechanism in this application, when the main body of the motor needs to replenish lubricating oil, the automatic oil replenishment mechanism will automatically replenish lubricating oil into the main body of the motor without having to take out the main body of the motor from the deep sea. Thus, the work efficiency can be greatly improved, the workload of the staff can be significantly reduced, and the staff only needs to go to the deep sea to replace the oil storage barrel when the lubricating oil in the oil storage barrel is exhausted, which can greatly reduce the frequency and number of times of going to the deep sea to replenish lubricating oil for the main body of the motor.

[0014] (2) Through the combined setting of the reminder switch, the rubber sealing sleeve, the replacement reminder module, the remote connection module, etc., when there is not much lubricating oil left in the oil storage barrel, the remote connection module will send a reminder signal to the staff, prompting the staff to replace the oil storage barrel in a timely manner, thereby ensuring that the main body of the motor can be effectively replenished when it lacks oil.

[0015] (3) Through the setting of the automatic water blocking plug, the automatic water blocking plug can play a sealing role without affecting the replenishment of lubricating oil into the main body of the motor, preventing seawater from flowing into the main body of the motor through the oil replenishment pipe when replacing the oil storage barrel, greatly improving the practicability.

[0016] (4) A plurality of drain holes are provided on the outer wall of the top end of the connecting sleeve, and the plurality of drain holes are evenly distributed along the ring, so that the drain holes are conducive to the discharge of seawater in the connecting sleeve, preventing seawater from entering the main body of the motor through the oil supply pipe when replenishing lubricating oil to the main body of the motor. An oil filling pipe is communicated with the outer wall of the oil storage barrel, and a sealing cover matching therewith is arranged at one end of the oil filling pipe, so that after the replaced oil storage barrel is taken back to the land by the staff, lubricating oil can be re-filled into the oil storage barrel through the oil filling pipe, so that the oil storage barrel can be reused, improving the practicability.

[0017] (5) Through the arrangement of the enhanced water-blocking component, when replacing the oil storage barrel, by simple adjustment, the clamping rod block can be made to clamp the guiding sliding rod, so as to prevent the movable plug block from moving downward under the action of water pressure, thereby further preventing seawater from flowing into the main body of the motor through the oil supply pipe.

[0018] (6) Through the arrangement of the damage detection and maintenance promotion component, when the protective chassis is damaged, the damage detection and maintenance promotion component will detect this phenomenon and send an alarm to relevant staff through the remote connection module, prompting the staff to perform corresponding maintenance on the protective chassis in time, thereby greatly reducing the erosion of seawater on the main body of the motor.

[0019] (7) A water guiding rod is fixedly connected to the top end of the water guiding bottom plate, and water guiding ropes are fixedly connected to the outer walls on both the left and right sides of the water guiding rod. The water guiding rod and the water guiding ropes are both made of water-absorbing materials, and the water guiding rod and the water guiding ropes are both embedded in the damage detection and corrosion inhibitor. The water guiding rod and the water guiding ropes can accelerate the conduction of seawater into the damage detection and corrosion inhibitor, thereby accelerating the expansion of the damage detection and corrosion inhibitor, and further improving the response efficiency of the damage detection and maintenance promotion component.

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0033] Embodiment 1:

[0034] Please refer to Figure 1-7, this application discloses a deep-sea oil-immersed submersible motor, which includes a protective chassis 101. Inside the protective chassis 101, a motor main body 102 is fixedly installed. A supplementary oil pipe 103 is arranged on the motor main body 102. An oil level sensor for detecting the remaining amount of lubricating oil in the machine body is arranged inside the motor main body 102. An automatic oil replenishment mechanism is arranged on the protective chassis 101. The automatic oil replenishment mechanism includes an oil storage barrel 201 located above the protective chassis 101. A pressure oil piston plate 202 that is slidably and sealingly connected thereto is arranged inside the oil storage barrel 201. Lubricating oil is filled below the pressure oil piston plate 202. An electric telescopic rod 203 is fixedly installed on the inner wall of the top end of the oil storage barrel 201. The output end of the electric telescopic rod 203 is fixedly connected to the pressure oil piston plate 202. The bottom end of the oil storage barrel 201 communicates with an oil replenishment one-way valve 204. The bottom end of the oil replenishment one-way valve 204 is connected to a connecting sleeve 205 that matches the supplementary oil pipe 103. The connecting sleeve 205 is threadedly and sealingly connected to the supplementary oil pipe 103. The one-way conduction direction of the oil replenishment one-way valve 204 is from top to bottom. A protective cover 206 is fixedly installed on the outer wall of the oil storage barrel 201. A self-replenishing intelligent controller 207 is fixedly installed inside the protective cover 206. An oil quantity monitoring module and an oil replenishment control module are arranged in the self-replenishing intelligent controller 207. The oil level sensor is wirelessly signal-connected to the oil quantity monitoring module. The oil quantity monitoring module is electrically connected to the oil replenishment control module. The oil replenishment control module is electrically connected to the electric telescopic rod 203.

[0035] Please refer to Figure 1-5 , the oil level sensor can monitor the remaining amount of lubricating oil in the motor main body 102, and the monitored data will be transmitted to the oil quantity monitoring module. When the oil quantity monitoring module analyzes the data and finds that the motor main body 102 needs to be replenished with lubricating oil, it will send a signal to the oil replenishment control module, causing the oil replenishment control module to start the electric telescopic rod 203, resulting in the electric telescopic rod 203 driving the pressure oil piston plate 202 to move downward by a certain distance. The downward movement of the pressure oil piston plate 202 will squeeze the lubricating oil below it, causing the lubricating oil to flow into the motor main body 102 through the oil replenishment one-way valve 204 and the supplementary oil pipe 103, so as to achieve the purpose of replenishing lubricating oil to the motor main body 102. Therefore, through the setting of the automatic oil replenishment mechanism, when the motor main body 102 needs to be replenished with lubricating oil, the automatic oil replenishment mechanism will automatically replenish lubricating oil to the motor main body 102 without having to take out the motor main body 102 from the deep sea. Furthermore, the work efficiency can be greatly improved, the workload of the staff can be significantly reduced, and the staff only needs to go to the deep sea to replace the oil storage barrel 201 when the lubricating oil in the oil storage barrel 201 is exhausted, which can greatly reduce the frequency and number of times of going to the deep sea to replenish lubricating oil to the motor main body 102.

[0036] Please refer to Figure 3 and Figure 5, a reminder switch 208 is fixedly installed on the inner wall of the bottom end of the oil storage barrel 201. A rubber sealing sleeve 209 that matches it is provided outside the reminder switch 208. The rubber sealing sleeve 209 is made of oil-resistant rubber material. The self-supplementary intelligent controller 207 is also provided with a replacement reminder module and a remote connection module based on Internet of Things technology. The reminder switch 208 is electrically connected to the replacement reminder module, and the replacement reminder module is electrically connected to the remote connection module. As the number of times of replenishing lubricating oil increases, the height of the oil pressing piston plate 202 will gradually decrease, and the lubricating oil below the oil pressing piston plate 202 will also gradually decrease. When the oil pressing piston plate 202 drops to a certain extent, that is, when the remaining amount of lubricating oil below the oil pressing piston plate 202 is not much, the oil pressing piston plate 202 will squeeze and trigger the reminder switch 208. After the reminder switch 208 is triggered, the replacement reminder module will send a reminder signal to the remote connection module, and the remote connection module can send the reminder signal to relevant staff through the Internet of Things (the signal will be sent to electronic devices controlled by the staff, such as computers, mobile phones, etc.). Therefore, through the combined setting of the reminder switch 208, the rubber sealing sleeve 209, the replacement reminder module, the remote connection module, etc., when the remaining lubricating oil in the oil storage barrel 201 is not much, the remote connection module will send a reminder signal to the staff, prompting the staff to replace the oil storage barrel 201 in time (replacing the oil storage barrel 201 means that the staff carry an oil storage barrel 201 with sufficient oil to the deep sea and replace the oil storage barrel 201 with insufficient oil), so as to ensure that the main motor 102 can be effectively replenished when it lacks oil.

[0037] Please refer to Figure 4 and Figure 6-7 , an automatic water-blocking plug member is arranged in the oil replenishing pipe 103. The automatic water-blocking plug member includes a fixed plug block 301 that matches the oil replenishing pipe 103 and is fixedly installed in the oil replenishing pipe 103. The top end of the fixed plug block 301 is flush with the top end of the oil replenishing pipe 103. A oil guiding hole 302 is opened in the middle of the fixed plug block 301. The oil guiding hole 302 is set as a frustum shape with a narrow upper part and a wide lower part. A movable plug block 303 that matches it is slidably and sealingly connected in the oil guiding hole 302. The automatic water-blocking plug member also includes a support net 304 installed in the oil replenishing pipe 103. The support net 304 is located below the fixed plug block 301. A sealing guide cylinder 305 is fixedly installed at the top end of the support net 304. A guide slide rod 306 that is slidably and sealingly connected to it is penetrated through the outer wall of the top end of the sealing guide cylinder 305. The top end of the guide slide rod 306 is fixedly connected to the movable plug block 303. A pair of resistance support elastic ropes 307 are fixedly connected between the top end inner wall of the guide slide rod 306 and the sealing guide cylinder 305. When replenishing lubricating oil into the main motor 102, when the lubricating oil in the oil storage barrel 201 flows to the fixed plug block 301 through the oil replenishing one-way valve 204, as Figure 7As shown, under the action of oil pressure, the movable plug 303 will drive the guide slide bar 306 to move downward and stretch the elastic rope 307. The downward movement of the movable plug 303 will open the oil guide hole 302, so that the lubricating oil can flow into the oil replenishing pipe 103 through the oil guide hole 302, thereby not affecting the replenishment of the lubricating oil. After the lubricating oil is replenished, the elastic rope 307 will rebound to drive the guide slide bar 306 and the movable plug 303 to move upward and reset, so that the oil guide hole 302 is blocked again. When the barrel 201 is replaced, the connecting sleeve 205 will be separated from the oil replenishing pipe 103. Under the blocking effect of the fixed plug 301 and the movable plug 303, seawater cannot flow into the motor body 102 through the oil replenishing pipe 103. Therefore, by setting the automatic water-blocking plug, the automatic water-blocking plug can play a sealing role without affecting the replenishment of lubricating oil into the motor body 102, thereby preventing seawater from flowing into the motor body 102 through the oil replenishing pipe 103 when the oil storage barrel 201 is replaced, thereby greatly improving practicality.

[0038] See also Figure 3-4 A plurality of drainage holes 210 are provided on the outer wall of the top of the connecting sleeve 205. The plurality of drainage holes 210 are evenly distributed along a ring. When the oil storage barrel 201 is replaced, the new oil storage barrel 201 needs to be connected to the oil replenishing pipe 103 through the connecting sleeve 205 on the oil storage barrel 201. Due to the location in the deep sea, the connecting sleeve 205 will be filled with seawater. During the connection process between the connecting sleeve 205 and the oil replenishing pipe 103, the seawater will be discharged through the drainage holes 210 under the pressure of the oil replenishing pipe 103 and the fixed plug 301, so that the drainage holes 210 can be It is beneficial to discharge the seawater in the connecting sleeve 205, and prevents seawater from entering the motor body 102 through the oil filling pipe 103 when the motor body 102 is replenished with lubricating oil. The outer wall of the oil storage barrel 201 is connected with an oil filling pipe 211, and a matching sealing cover is provided at one end of the oil filling pipe 211, so that after the staff brings the replaced oil storage barrel 201 back to the land, the lubricating oil can be refilled into the oil storage barrel 201 through the oil filling pipe 211, so that the oil storage barrel 201 can be reused, thereby improving practicality.

[0039] Embodiment 2:

[0040] See also Figure 8-10, where the same or corresponding components as those in Embodiment 1 are denoted by the corresponding reference numerals in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between Embodiment 2 and Embodiment 1 is that: an enhanced water-blocking assembly is further provided on the oil replenishing pipe 103. The enhanced water-blocking assembly includes an inner support cylinder 401 fixedly installed on the inner wall of the oil replenishing pipe 103 and an outer support cylinder 402 fixedly installed on the outer wall of the oil replenishing pipe 103. A linkage movable block 403 is slidably and sealingly connected inside the inner support cylinder 401. One end of the linkage movable block 403 close to the sealing guide cylinder 305 is fixedly connected with a clamping rod block 404, and the other end of the linkage movable block 403 is fixedly connected with a spring 405. The spring 405 is in a compressed state. A driving and adjusting magnet 406 is fixedly installed inside the outer support cylinder 402. The linkage movable block 403 is made of metallic iron. The clamping rod block 404 penetrates through the outer wall of the sealing guide cylinder 305 and is slidably connected therewith. The top end of the clamping rod block 404 is flush with the bottom end of the guiding slide rod 306. A magnetic shielding cover cylinder 407 is sleeved on the outer wall of the outer support cylinder 402. The magnetic shielding cover cylinder 407 is threadedly connected with the driving and adjusting magnet 406. The magnetic shielding cover cylinder 407 is made of a magnetic shielding material. Under the action of the magnetic attraction of the driving and adjusting magnet 406, the linkage movable block 403 has a movement tendency to approach the driving and adjusting magnet 406, so that the spring 405 is in a compressed state. When replacing the oil storage barrel 201, before removing the oil storage barrel 201 with insufficient oil, the magnetic shielding cover cylinder 407 can be rotated first to completely wrap the outer support cylinder 402 with the magnetic shielding cover cylinder 407, so that the magnetic force of the driving and adjusting magnet 406 is greatly reduced, enabling the spring 405 to rebound, driving the clamping rod block 404 to slide into the sealing guide cylinder 305, causing the top end of the clamping rod block 404 to abut against the bottom end of the guiding slide rod 306, thereby clamping the guiding slide rod 306 and preventing the guiding slide rod 306 from moving downward. After replacing the oil storage barrel 201, the magnetic shielding cover cylinder 407 is rotated again to expose the outer support cylinder 402, and the magnetic force of the driving and adjusting magnet 406 can be restored to separate the clamping rod block 404 from the guiding slide rod 306 and reset it. Therefore, through the setting of the enhanced water-blocking assembly, when replacing the oil storage barrel 201, the clamping rod block 404 can be simply adjusted to clamp the guiding slide rod 306, preventing the movable plug block 303 from moving downward under the action of water pressure, and further preventing seawater from flowing into the motor main body 102 through the oil replenishing pipe 103.

[0041] Please refer to Figure 8 and Figure 10, a damage detection and repair promotion component is also arranged inside the protective chassis 101. The damage detection and repair promotion component includes a water guide bottom plate 501 fixedly installed on the inner wall of the bottom end of the protective chassis 101. A regulating cylinder 502 is fixedly connected to the top end of the water guide bottom plate 501. A trigger piston plate 503 is slidably and sealingly connected inside the regulating cylinder 502. A damage detection driving agent 504 is filled below the trigger piston plate 503. An alarm switch 505 is fixedly installed on the inner wall of the top end of the regulating cylinder 502. The alarm switch 505 is wirelessly signal-connected to the remote connection module. The water guide bottom plate 501 is made of a water-absorbing material, and the damage detection driving agent 504 is made of a water-absorbing and expanding material. Seawater has certain corrosiveness, and the protective chassis 101 can play a protective role to prevent the seawater from corroding the motor main body 102. However, over time, the protective chassis 101 will inevitably be damaged due to reasons such as seawater corrosion and the impact of marine organisms. Once the protective chassis 101 is damaged, the seawater will flow into the protective chassis 101 from the damaged part, resulting in the motor main body 102 being eroded by the seawater. In the embodiment, when the protective chassis 101 is damaged and seawater flows in, part of the seawater will be guided by the water guide bottom plate 501 to the damage detection driving agent 504, causing the damage detection driving agent 504 to absorb water and expand. The expansion of the damage detection driving agent 504 will push up the trigger piston plate 503 upward, causing the trigger piston plate 503 to squeeze the alarm switch 505. After the alarm switch 505 is triggered, it will send an alarm signal to the remote connection module, and the remote connection module can send the alarm signal to relevant staff, so that the staff can timely know the information that the protective chassis 101 is damaged. Therefore, through the setting of the damage detection and repair promotion component, when the protective chassis 101 is damaged, the damage detection and repair promotion component will detect this phenomenon and send an alarm to relevant staff through the remote connection module, prompting the staff to timely perform corresponding maintenance on the protective chassis 101, thereby greatly reducing the erosion of the seawater on the motor main body 102.

[0042] Please refer to Figure 10 , a water guide rod 506 is fixedly connected to the top end of the water guide bottom plate 501. Water guide ropes 507 are fixedly connected to the outer walls on the left and right sides of the water guide rod 506. The water guide rod 506 and the water guide ropes 507 are both made of water-absorbing materials, and the water guide rod 506 and the water guide ropes 507 are both embedded in the damage detection driving agent 504. The water guide rod 506 and the water guide ropes 507 can accelerate the conduction of seawater into the damage detection driving agent 504, thereby accelerating the expansion of the damage detection driving agent 504, and further improving the response efficiency of the damage detection and repair promotion component.
