Description

Technical Field

[0001] This utility model belongs to the field of jet pump salvage technology, and in particular relates to a salvage device for jet pumps. Background Technology

[0002] A jet pump is a fluid machine and mixing reaction device that uses high-speed fluid as its working power. It has no moving parts and has a series of unique advantages such as simple structure, good sealing, reliable operation and low cost. It is superior and irreplaceable in many process applications, especially in the petroleum industry, where the application of jet pump technology is quite extensive.

[0003] After prolonged operation, jet pumps are prone to clogging due to the presence of large particles, sand, and other impurities in the liquid. Once clogged, the jet pump cannot function properly, and retrieving it is extremely difficult. Failure to retrieve, clean, and maintain the jet pump in a timely manner will result in significant economic losses and impacts on production activities, and may also create potential hazards. Therefore, we propose a retrieval device for jet pumps. Utility Model Content

[0004] The purpose of this invention is to provide a retrieval device for jet pumps. By setting hooks, specifically, when the limiting ring moves outward, it compresses a spring. The spring, after being compressed, accumulates elastic force. When the device reaches the appropriate position, pulling the device upward causes the hooks to move upward along the jet pump due to the spring's properties. When the hooks reach the mounting ring of the jet pump, they tightly hook onto the ring, firmly fixing the jet pump to the device. This allows for effective replacement of the jet pump, reducing losses caused by jet pump malfunctions. It also solves the problem that existing jet pumps, after prolonged operation, are easily clogged due to the presence of large particles, sand, and other impurities in the liquid. Clogged jet pumps cannot function properly, and retrieval is very difficult. Failure to retrieve and maintain the jet pump in a timely manner will cause serious economic losses and impacts on production activities, and may also create potential hazards.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a retrieval device for jet pumps, including a disc, a hook fixedly connected to the top of the disc, and three long rods fixedly connected to the bottom of the disc;

[0007] Each of the three long rods has an extension block fixedly connected to its bottom. A base plate is fixedly connected to the opposite side of each of the three extension blocks. A cover plate is fixedly connected to the top of the base plate. The inside of the cover plate is fixedly connected to the outer surface of the long rod. A tripod is fixedly connected to the outer surface of each of the three long rods. A spring cylinder is fixedly connected inside each of the three tripods. A spring is installed inside each of the three spring cylinders. A limit ring is slidably connected inside each of the three spring cylinders. The opposite side of each of the three springs contacts the outer surface of the limit ring. A round rod is fixedly connected inside each of the three limit rings. Due to the nature of the spring, the hook will move upward along the jet pump under the action of the spring. When the hook moves to the hanging ring position of the jet pump, it will tightly hook onto the hanging ring.

[0008] Furthermore, the outer surface of the first round rod is slidably connected to the inside of the spring cylinder. Hooks are fixedly connected to the opposite sides of the three first round rods, and second round rods are fixedly connected to the opposite sides of the three hooks. A limiting cylinder is slidably connected to the outer surface of the second round rod. The top of the limiting cylinder is fixedly connected to the bottom of the tripod. A motor is fixedly connected to the top of the cover plate, and a gear is fixedly connected to the bottom output end of the motor. The hooks will move upward against the jet pump under the action of the spring. When the hooks move to the hanging ring position of the jet pump, they will tightly hook the hanging ring, firmly fixing the jet pump to the device. This can effectively replace the jet pump and reduce the losses caused by jet pump malfunctions.

[0009] Furthermore, a rotating disk is rotatably connected to the top of the base plate, and a gear ring is fixedly connected to the top of the rotating disk. The right side of the gear ring meshes with the left side of the gear. Three arc-shaped grooves are formed at the bottom of the rotating disk, and cylinders are slidably connected inside each of the three arc-shaped grooves. Three sliding grooves are formed at the top of the base plate, and limit blocks are slidably connected inside each of the three sliding grooves. The top of the limit blocks is fixedly connected to the bottom of the cylinders. Clamping blocks are fixedly connected to the opposite sides of the three limit blocks. The limit blocks are components used to limit the movement range of the clamping blocks. When they move inward, they will drive the clamping blocks to move inward as well. Finally, the clamping blocks will tightly clamp the jet pump, ensuring the stability of the salvage operation.

[0010] This utility model has the following beneficial effects:

[0011] 1. This utility model uses hooks. Specifically, when the limiting ring moves outward, it squeezes the spring. After being squeezed, the spring accumulates elastic force. When the device reaches the appropriate position, pulling the device upward causes the hooks to move upward along the jet pump due to the nature of the spring. When the hooks move to the hanging ring position of the jet pump, they will tightly hook onto the hanging ring, firmly fixing the jet pump to the device. This allows for effective replacement of the jet pump and reduces losses caused by jet pump malfunctions.

[0012] 2. This utility model uses a clamping block, specifically a cylinder connected to the clamping block. Its movement directly drives the movement of the clamping block. The movement of the cylinder causes the limiting block to move inward along the sliding groove inside the base plate. The limiting block is a component used to limit the movement range of the clamping block. When it moves inward, it will drive the clamping block to move inward as well. Finally, the clamping block will tightly clamp the jet pump, ensuring the stability of the salvage.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figure 1-6 As shown, this utility model is a salvage device for jet pumps, including a disc 2, a hook 1 fixedly connected to the top of the disc 2, and three long rods 3 fixedly connected to the bottom of the disc 2.

[0025] Each of the three long rods 3 has an extension block 61 fixedly connected to its bottom. A base plate 6 is fixedly connected to the opposite side of each of the three extension blocks 61. A cover plate 5 is fixedly connected to the top of the base plate 6. The inside of the cover plate 5 is fixedly connected to the outer surface of the long rods 3. A tripod 4 is fixedly connected to the outer surface of each of the three long rods 3. A spring cylinder 31 is fixedly connected inside each of the three tripod 4. A spring 311 is installed inside each of the three spring cylinders 31. A limit ring is slidably connected inside each of the three spring cylinders 31. The opposite side of each of the three springs 311 contacts the outer surface of the limit ring. A round rod 32 is fixedly connected inside each of the three limit rings.

[0026] The outer surface of the first round rod 32 is slidably connected to the inside of the spring cylinder 31. Hooks 33 are fixedly connected to the opposite side of each of the three round rods 32. Round rods 34 are fixedly connected to the opposite side of each of the three hooks 33. A limiting cylinder 35 is slidably connected to the outer surface of the second round rod 34. The top of the limiting cylinder 35 is fixedly connected to the bottom of the tripod 4. A motor 51 is fixedly connected to the top of the cover plate 5. A gear 54 is fixedly connected to the bottom output end of the motor 51. This utility model sets hooks 33 so that when the limiting ring moves outward, it will squeeze the spring 311. After being squeezed, the spring 311 will accumulate elastic force. When the device is in the appropriate position, the device is pulled upward. Due to the nature of the spring 311, the hooks 33 will move upward along the jet pump under the action of the spring 311. When the hooks 33 move to the position of the jet pump's hanging ring, they will tightly hook the hanging ring, firmly fixing the jet pump to the device. This can effectively replace the jet pump and reduce the losses caused by jet pump abnormalities.

[0027] A rotating disk 52 is rotatably connected to the top of the base plate 6. A gear ring 53 is fixedly connected to the top of the rotating disk 52. The right side of the gear ring 53 meshes with the left side of the gear 54. Three arc-shaped grooves are opened at the bottom of the rotating disk 52. A cylinder 55 is slidably connected inside each of the three arc-shaped grooves. Three sliding grooves are opened at the top of the base plate 6. A limit block 57 is slidably connected inside each of the three sliding grooves. The top of the limit block 57 is fixedly connected to the bottom of the cylinder 55. A clamping block 56 is fixedly connected to the opposite side of each of the three limit blocks 57. This utility model sets the clamping block 56. Specifically, the cylinder 55 is a component connected to the clamping block 56. Its movement will directly drive the movement of the clamping block 56. The movement of the cylinder 55 causes the limit block 57 to move inward along the sliding groove inside the base plate 6. The limit block 57 is a component used to limit the movement range of the clamping block 56. When it moves inward, it will drive the clamping block 56 to move inward as well. Finally, the clamping block 56 will tightly clamp the jet pump, ensuring the stability of the salvage.

[0028] One specific application of this embodiment is as follows: When preparing to retrieve a jet pump, first, hang the rope on the hook 1 of the retrieval device. After ensuring a secure connection, slowly lower the device to the designated location of the jet pump. During this process, keep the device stable to avoid accidental shaking or collision. When the device has descended to a certain extent, align the bottom inner side of the base plate 6 with the top of the jet pump. After alignment, continue lowering the device, allowing the jet pump to gradually pass through the interior of the base plate 6. During this process, the jet pump will touch the part of the base plate 6. The three internal hooks 33 move outward when compressed. Simultaneously, the movement of the hooks 33 also causes the connected circular rods 32 and 34 to move outward. The movement of the circular rod 32 further causes the limiting ring to move outward. The limiting ring is a component connected to the circular rod 32, and its function is to restrict the movement range of the hooks 33. When the limiting ring moves outward, it compresses the spring 311. The spring 311, after being compressed, accumulates elastic force. When the device reaches the appropriate position, it pulls the device upward. Due to the properties of spring 311, hook 33 will move upward along the jet pump under the action of spring 311. When hook 33 moves to the position of the jet pump's hanging ring, it will tightly hook onto the hanging ring, firmly fixing the jet pump to the device. At this time, motor 51 is started, and motor 51 drives gear 54 to start rotating. Gear 54 and gear ring 53 are meshed with each other, so when gear 54 rotates, it will drive gear ring 53 to rotate together through gear transmission. The rotation of gear ring 53 in turn drives the rotation of rotating disk 52. The bottom of the rotating disk 52 is provided with an arc-shaped groove. When the rotating disk 52 rotates, the arc-shaped groove will drive the cylinder 55 in contact with it to move. The cylinder 55 is a component connected to the clamping block 56. Its movement will directly drive the movement of the clamping block 56. The movement of the cylinder 55 causes the limiting block 57 to move inward along the sliding groove inside the base plate 6. The limiting block 57 is a component used to limit the movement range of the clamping block 56. When it moves inward, it will drive the clamping block 56 to move inward as well. Finally, the clamping block 56 will tightly clamp the jet pump, ensuring the stability of the salvage.
