Description

Technical Field

[0001] This utility model relates to the field of cooling tower water turbine technology, and in particular to a multi-stage pressurized cooling tower water turbine. Background Technology

[0002] A cooling tower turbine is a device used in a cooling tower system. The turbine typically uses the residual pressure energy of the circulating water to convert it into mechanical energy, which drives the turbine to rotate. Multi-stage pressurized cooling tower turbines achieve pressurization by cascading multiple impellers.

[0003] According to the search, the Chinese patent "A cooling tower water turbine with anti-leakage function" authorized announcement number "CN217233690U" fixes the water turbine inside the cooling water tower with a bolt structure, and the installation of the water turbine is simple.

[0004] In the aforementioned application, because the air inside the cooling tower is quite humid and the bolts are exposed, the moisture in the air easily adheres to the surface of the bolts, which can easily cause the bolts to rust, thus affecting the stable installation of the water turbine.

[0005] Therefore, a multi-stage pressurized cooling tower turbine is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a multi-stage pressurized cooling tower turbine to solve the above-mentioned problems, thereby improving the problem that moisture in the air easily adheres to the surface of bolts, which in turn easily leads to bolt rust.

[0007] This utility model achieves the above-mentioned objectives through the following technical solution: a multi-stage pressurized cooling tower turbine, comprising: a turbine casing and a base; annularly distributed bolts threaded to the lower end of the inner wall of the turbine casing, the surfaces of which are threaded to the inner wall of the base; and a sealing mechanism, comprising sealing blocks slidably connected to annularly distributed sealing blocks at the lower end of the inner wall of the turbine casing, a sealing ring fixedly connected to the surface of the sealing blocks; a slot formed at the lower end of the inner wall of the turbine casing; a locking rod slidably connected to the inner wall of the sealing ring, the surface of which is slidably connected to the inner wall of the slot; and a resistance-increasing rod slidably connected to the inner wall of the sealing ring, the surface of which is engaged with the inner wall of the locking rod. Through the cooperation of the locking rod, the slot, and the resistance-increasing rod, the sealing ring is locked, thereby ensuring that the sealing blocks stably seal the pre-reserved holes on the turbine casing, preventing moisture in the air from adhering to the bolt surfaces, avoiding rusting of the bolt surfaces, and ensuring the stable installation of the turbine inside the cooling tower.

[0008] Preferably, the inner wall of the sealing ring is fixedly connected with annularly distributed barrier pads, the ends of which contact the ends of the resistance-increasing rod. The barrier pads increase the resistance to the movement of the resistance-increasing rod, thereby ensuring that the resistance-increasing rod is stably engaged within the locking rod, thus guaranteeing the locking effect on the sealing ring.

[0009] Preferably, an iron block is fixedly connected to the top of the sealing ring.

[0010] Preferably, a magnetic block is slidably connected to the surface of the clamping rod, and the surface of the magnetic block is magnetically attracted to the side of the iron block. The interaction between the magnetic block and the iron block increases the resistance during the rotation of the clamping rod, thereby ensuring that the clamping rod is stably positioned within the groove, thus guaranteeing the locking effect on the sealing ring.

[0011] Preferably, a limiting ring is fixedly connected to the inner wall of the sealing ring, and the end of the barrier pad contacts one end of the limiting ring. The limiting ring limits the flipping direction of the barrier pad, preventing the barrier pad from flipping inward into the sealing ring.

[0012] Preferably, an anti-detachment ring is fixedly connected to the surface of the resistance-increasing rod, and the surface of the anti-detachment ring is slidably connected to the inner wall of the sealing ring. The anti-detachment ring restricts the movement range of the resistance-increasing rod, preventing it from detaching from the sealing ring.

[0013] Preferably, a cover is fixedly connected to the top of the sealing ring, the iron block and the magnetic block are both located inside the cover, and the surface of the lever is slidably connected to the inner wall of the cover.

[0014] The beneficial effects of this utility model are:

[0015] By using a locking rod, a locking groove, and a resistance rod in combination, the sealing ring is locked, thereby ensuring that the sealing block stably seals the reserved hole on the turbine casing. Compared with existing methods where moisture in the air easily adheres to the bolt surface, this method seals and protects the bolt surface, thereby preventing moisture in the air from adhering to the bolt surface, avoiding the problem of rust on the bolt surface, and ensuring that the turbine is stably installed in the cooling tower.

[0016] The resistance to the movement of the resistance-increasing rod is increased by the blocking pad, thereby ensuring that the resistance-increasing rod is stably locked in the locking rod. The magnetic block and the iron block cooperate with each other to increase the resistance during the rotation of the locking rod, thereby ensuring that the locking rod is stably located in the locking groove, thus ensuring the locking effect of the sealing ring.

[0022] 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 protection scope of the present utility model.

[0023] In practical implementation: such as Figure 1-4 As shown, a multi-stage pressurized cooling tower turbine includes: a turbine casing 1 and a base 2. The lower end of the inner wall of the turbine casing 1 is threaded with annularly distributed bolts 3, and the surface of the bolts 3 is threaded to the inner wall of the base 2. A sealing mechanism 4 includes a sealing block 41 slidably connected to the lower end of the inner wall of the turbine casing 1, annularly distributed sealing block 41, a sealing ring 42 fixedly connected to the surface of the sealing block 41, a groove 44 opened at the lower end of the inner wall of the turbine casing 1, a locking rod 43 slidably connected to the inner wall of the sealing ring 42, the surface of the locking rod 43 slidably connected to the inner wall of the groove 44, and a resistance-increasing rod 45 slidably connected to the inner wall of the sealing ring 42, the surface of the resistance-increasing rod 45 being engaged with the inner wall of the locking rod 43.

[0024] A multi-stage booster turbine typically consists of a turbine casing, multiple sets of impellers, a main shaft, bearings, and sealing devices.

[0025] Impeller: The core component of a water turbine, consisting of blades, hub, etc. Water flow impacts the blades of the impeller, causing the impeller to rotate.

[0026] Turbine casing 1: Used to house the runner and guide the water flow along a predetermined path, while also protecting the runner and supporting the entire turbine.

[0027] Main shaft: connects the impeller and the cooling tower fan, and transmits the rotational power of the impeller to the fan.

[0028] Bearings: Support the spindle, ensure its smooth rotation, and reduce friction and wear.

[0029] Sealing device: Prevents water leakage and ensures the normal operation of the turbine.

[0030] In this embodiment of the utility model, the base 2 is welded to the corresponding position inside the cooling tower. The turbine casing 1 is hoisted and aligned to the top of the base 2. An electric wrench is used to thread multiple bolts 3 into the turbine casing 1 and the base 2 in sequence, thereby fixing the turbine casing 1 onto the base 2. The sealing ring 42 is pushed, and multiple sealing blocks 41 are rotated to a suitable position at the lower end of the inner wall of the turbine casing 1. Then, the locking rod 43 is pushed down, and the locking rod 43 slides into the locking groove 44. At this time, the locking rod 43 is rotated so that the lower end of the surface of the locking rod 43 abuts against the locking groove 44. The resistance rod 45 is pushed to engage with the locking rod 43, thereby locking the sealing ring 42 and the sealing block 41, thus sealing the reserved hole on the turbine casing 1.

[0031] The pipes of the water supply system inside the cooling tower are connected to the turbine casing 1 by flanges. Water from the cooling tower is circulated into the turbine casing 1 through the water supply system. The circulating water in the turbine casing 1 first enters the first-stage impeller. The water flow impacts the impeller, causing it to rotate and converting some of the water energy into mechanical energy. At the same time, the pressure and velocity of the water flow will change. Then, the water flow enters the next stage impeller, repeating the energy conversion and pressurization process. Each stage impeller further converts and pressurizes the water flow, ultimately achieving a higher pressure output to meet the needs of the cooling tower system.

[0032] At this time, the circulating water discharged from the turbine casing 1 passes through the spray system inside the cooling tower and sprays water from top to bottom inside the cooling tower, forming water droplets or water film. The impeller rotates, driving the fan to rotate. The rotating fan enters from the side of the cooling tower and has full contact and heat exchange with the water. After heat exchange, the cooled water is collected in the water collection pool at the bottom of the cooling tower and can be recycled again, while the air that has absorbed heat is discharged outside the tower.

[0033] like Figure 3-4 As shown, a ring-shaped blocking pad 48 is fixedly connected to the inner wall of the sealing ring 42. The end of the blocking pad 48 contacts the end of the resistance-increasing rod 45. An iron block 46 is fixedly connected to the top of the sealing ring 42. A magnetic block 47 is slidably connected to the surface of the locking rod 43. The surface of the magnetic block 47 is magnetically attracted to the side of the iron block 46. A limiting ring 49 is fixedly connected to the inner wall of the sealing ring 42. The end of the blocking pad 48 contacts one end of the limiting ring 49. A cover 411 is fixedly connected to the top of the sealing ring 42. The iron block 46 and the magnetic block 47 are both located inside the cover 411. The surface of the locking rod 43 is slidably connected to the inner wall of the cover 411. The sealing block 41, sealing ring 42, locking rod 43, cover 411, and blocking pad 48 are all silicone rubber components.

[0034] In this embodiment of the invention, the rotation of the lever 43 drives the magnetic block 47 to rotate, causing the magnetic block 47 to rotate and abut against the side of the iron block 46, thus stopping the rotation of the lever 43.

[0035] like Figure 3 As shown, an anti-detachment ring 410 is fixedly connected to the surface of the resistance rod 45, and the surface of the anti-detachment ring 410 is slidably connected to the inner wall of the sealing ring 42.

[0036] In use, the sealing ring 42 is pushed so that multiple sealing blocks 41 rotate to a suitable position at the lower end of the inner wall of the turbine casing 1. Then, the locking rod 43 is pushed down so that it slides into the slot 44. At this time, the locking rod 43 is rotated, which drives the magnetic block 47 to rotate. The magnetic block 47 rotates and abuts against the side of the iron block 46. The rotation of the locking rod 43 is stopped, and the lower end of the surface of the locking rod 43 abuts against the slot 44. The resistance rod 45 is pushed and engaged in the locking rod 43. The blocking pad 48 elastically limits the end of the resistance rod 45, thereby locking the sealing ring 42 and the sealing block 41, thus sealing the reserved hole on the turbine casing 1.

[0037] It should be noted that the turbine casing 1, base 2, bolt 3, iron block 46 and magnet 47 mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
