Description

Technical Field

[0001] This utility model relates to the field of hot water storage tank technology, specifically to a hot water storage tank for peak heating regulation. Background Technology

[0002] Hot water storage tanks used for peak heating are mostly large hot water storage tanks. The upper and lower layers inside are equipped with water distributors arranged in a circumferential direction to evenly distribute the high-temperature water flow in the upper layer and the low-temperature water flow in the lower layer. The water distributor is a key component that determines the performance of the hot water storage tank. During long-term operation, the water distributor is prone to problems such as nozzle blockage, loose structure or corrosion, and needs to be inspected and maintained regularly.

[0003] Currently, maintenance work on the water distributor requires maintenance personnel to climb ladders installed inside the tank. Maintenance personnel can only inspect the water distributor pipes near the ladders, making it difficult to comprehensively inspect the water distributor pipes at all locations around the tank. If more ladders are installed around the tank, these large-volume obstacles will disrupt the hydraulic stability inside the hot water storage tank, affect temperature stratification, and increase heat loss from the hot water storage tank.

[0004] How to design a structure on hot water storage tanks used for peak heating that is easy to maintain without affecting heat storage is an urgent problem to be solved. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a hot water storage tank for peak heating regulation, thereby resolving the issues of the prior art.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] A hot water storage tank for peak heating includes a tank body, a maintenance assembly, and a lifting assembly. The lifting assembly is located on the top of the tank body and includes a rotating platform and a moving block. The rotating platform is rotatably connected to the center of the top of the tank body. The maintenance assembly is connected to the lifting assembly via a lifting rope. Several manholes are evenly distributed around the top of the tank body. A foldable or unfoldable maintenance platform is provided at the bottom of the maintenance assembly.

[0012] Furthermore, an electric hoist is installed on one side of the upper surface of the rotating platform, and a rotating pulley frame is set on the other side of the upper surface of the rotating platform. The hoisting rope on the electric hoist passes around the rotating pulley frame and the moving pulley frame in turn, and the end of the hoisting rope is connected to the support through a rope group with a hook.

[0013] Furthermore, the tank also includes multiple water distributors arranged from top to bottom. The pipes of each water distributor are arranged circumferentially inside the tank. A fixed seat is set at the center of the top of the tank, and the fixed seat is rotatably connected to the rotating platform.

[0027] Furthermore, the tank body 1 includes a water distributor 11, and there are multiple water distributors 11 arranged from top to bottom in the tank body 1. The pipe of each water distributor 11 is arranged circumferentially inside the tank body 1. A fixed seat 15 is provided at the center of the top of the tank body 1. The rotating platform 31 is rotatably connected to the fixed seat 15. A fence 12 extends upward from the outer edge of the top of the tank body 1. Several grooves 14 are evenly opened circumferentially from top to bottom on the inner wall of the fence 12. The grooves 14 extend through the manhole 13 to the bottom of the inner wall of the tank body 1. An annular guide rail 121 is provided inside the fence 12. Several pin holes 122 are evenly opened circumferentially on the side of the annular guide rail 121 near the fixed seat 15. The position of the pin holes 122 corresponds one-to-one with the position of the manhole 13. Preferably, a cover plate with a matching shape is detachably provided at the manhole 13.

[0028] Furthermore, the maintenance component 2 includes a support frame 21 and a ladder 24. The upper and lower ends of the support frame 21 are respectively provided with a walking platform 211 and a passage base plate for maintenance personnel to stand and walk. The four upper corners of the support frame 21 are provided with hanging ears 212 for connection to the suspension rope 321. The ladder 24 is arranged from top to bottom inside the support frame 21. The upper and lower ends of the ladder 24 are fixedly connected to the walking platform 211 and the passage base plate respectively, for maintenance personnel to climb on the upper and lower ends of the support frame 21. Several support rods are spaced from top to bottom between the ladder 24 and the support frame 21 to ensure the stability of the ladder 24. Handrails are vertically arranged on both sides of the ladder 24. To facilitate climbing by maintenance personnel, a passageway 213 is provided below the support 21 at a position away from the ladder 24 for maintenance personnel to pass through. A lower cylinder 251 is provided on the side of the support 21 near the inner wall of the tank 1. A slider 25 is fixedly connected to the piston end of the lower cylinder 251. The shape of the slider 25 matches the shape of the slide groove 14 to keep the maintenance component 2 stable inside the tank 1. A lower roller 252 is installed on the side of the slider 25 away from the piston end of the lower cylinder 251. When the piston end of the lower cylinder 251 extends to the point where the slider 25 is inserted into the slide groove 14, the lower roller 252 is in rolling connection with the slide groove 14, and the slider 25 can slide along the slide groove 14.

[0029] Furthermore, the maintenance assembly 2 also includes two winch units 23, which are symmetrically arranged on the support 21. Each winch unit 23 includes two winches, which are symmetrically arranged on the side of the support 21 near the inner wall of the tank 1 and on the side away from the inner wall of the tank 1, respectively. There are two maintenance platforms 22, which are symmetrically arranged at the lower part of the support 21. One end of each maintenance platform 22 is hinged to the bottom of the support 21, and the other end of each maintenance platform 22 is connected to the support 21 via... The pull rope 231 is connected to the two winches of the corresponding winch unit 23. When the winch unit 23 pulls the pull rope 231, the maintenance platform 22 rotates to the vertical under the action of the traction force, and the maintenance component 2 passes through the manhole 13. When the winch unit 23 releases the pull rope 231, the maintenance platform 22 unfolds to the horizontal under the action of gravity, so that maintenance personnel can walk on the maintenance platform 22 to carry out maintenance on the water distributor 11 pipeline. The maintenance platform 22 is equipped with a guardrail 221 in the vertical direction to prevent maintenance personnel from falling accidentally.

[0030] Furthermore, the lifting assembly 3 also includes an electric hoist 32. A rotating platform 31 is disposed above a fixed base 15. A rotating shaft 311 is fixedly connected below the rotating platform 31. The rotating shaft 311 is rotatably connected to the fixed base 15. A drive motor is installed above the fixed base 15. The output shaft of the drive motor is connected to a drive gear 313. A driven gear 312 is coaxially disposed at the lower part of the rotating shaft 311. The driven gear 312 meshes with the drive gear 313. When the drive motor is started, the driven gear 312 rotates around the axis of the rotating shaft 311 under the meshing action with the drive gear 313, thereby driving the rotating platform 31 to rotate. The electric hoist 32 is installed on one side of the upper surface of the rotating platform 31. A rotating pulley frame 322 is disposed on the other side of the upper surface of the rotating platform 31. The lifting rope 321 of the electric hoist 32 passes around the rotating pulley frame 322 and extends to the moving block 33 to change the direction of the traction force.

[0031] Furthermore, the movable block 33 cooperates with the annular guide rail 121. A boss extends downwards from the end of the movable block 33 away from the fixed base 15, inserting into the groove formed by the annular guide rail 121 and the guardrail 12. An upper roller 331 is provided below the boss, rolling against the inner surface of the groove. A movable pulley frame 334 is provided at the end of the movable block 33 near the fixed base 15. The lifting rope 321, after passing over the rotating pulley frame 322, passes over the movable pulley frame 334 again. The end of the lifting rope 321 is connected to the hanging lug 212 via a rope group with a hook, thereby allowing the maintenance assembly 2 to be lowered and raised under the traction of the lifting rope 321. The upper cylinder 333 is located on the side of the movable pulley frame 334 away from the fixed seat 15. The piston end of the upper cylinder 333 is fixedly connected to the fixing pin 332. The fixing pin 332 cooperates with the pin hole 122. When the piston end of the upper cylinder 333 extends, the fixing pin 332 is inserted into the pin hole 122 opened in the annular guide rail 121, locking the moving block 33, thereby maintaining the stability of the maintenance component 2 during the lowering and lifting process. When the moving block 33 needs to be moved above another manhole 13, the piston end of the upper cylinder 333 retracts, driving the fixing pin 332 to unlock from the pin hole 122, and the moving block 33 moves along the annular guide rail 121.

[0032] In this embodiment, during maintenance, the drive motor is started, and the rotating pulley frame 322 is rotated to a position between a manhole 13 and the electric hoist 32. The moving block 33 and the maintenance component 2 are moved along the annular guide rail 121 to a position corresponding to the manhole 13. The upper cylinder 333 is started, and the moving block 33 is locked on the annular guide rail 121. The lower cylinder 251 is started, and the slider 25 is inserted into the slide groove 14, opening the manhole 13. The electric hoist 32 is started, and the hoisting rope 321 is lowered. The maintenance component 2 is lowered into the tank 1 along the slide groove 14 from the manhole 13. The winch unit 23 releases the pull rope 231, and the maintenance platform 22 is unfolded to the horizontal. Maintenance personnel climb up the ladder 24 to the lower walking platform 211. After the maintenance component 2 is lowered to different heights, the maintenance personnel enter the maintenance platform 22 at different heights to inspect the water distributor 11 pipe and inner wall structure of the tank 1.

[0033] After the water distributor 11 pipe and inner wall structure at the corresponding position of the manhole 13 in the tank body 1 are inspected and repaired, the winch unit 23 pulls the pull rope 231, the maintenance platform 22 rotates to the vertical position, the electric hoist 32 is started in reverse, the maintenance component 2 leaves the inside of the tank body 1 through the manhole 13, the maintenance personnel climb out of the support 21 along the ladder 24, close the manhole 13, open the other manholes 13 one by one, and repeat the above work to inspect and repair the water distributor 11 pipe and inner wall structure at the corresponding positions of the remaining manholes 13. Without the need to set up many large internal ladders, the water distributor 11 at different circumferential positions and different heights and the inner wall structure of the tank body 1 can be fully inspected without damaging the hydraulic stability inside the tank body 1, and without affecting the temperature stratification and heat loss when the hot water storage tank is working.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
