Automatic spraying device for steam turbine generator base maintenance

Abstract

This utility model discloses an automatic spraying device for the maintenance of a steam turbine generator base, including a support frame composed of columns and connecting beams. A push handle is fixedly connected to the columns of the support frame, and casters are installed at the bottom of the columns. A guide rod is fixedly connected between the two columns of the support frame. A first slider and a second slider are slidably fitted on the guide rod. A retaining ring is provided on the guide rod, and a spring is installed between the retaining ring and the first slider. A cam abuts against the second slider. This utility model uses a rotary motor to drive the cam to rotate, causing the cam to intermittently compress the second slider, resulting in reciprocating motion of the first and second sliders, which in turn drives the atomizing nozzle to reciprocate. Simultaneously, a water pump delivers water to the atomizing nozzle for spraying, ensuring that the water is evenly sprayed onto the steam turbine generator base, thus achieving comprehensive maintenance of the steam turbine generator base and ensuring the normal hardening and strength development of the concrete corresponding to the steam turbine generator base.

Description

Technical Field

[0001] This utility model relates to the field of concrete curing technology, specifically to an automatic spraying device for curing steam turbine generator bases. Background Technology

[0002] The turbine generator base is a core structure of a thermal power plant, bearing the enormous dynamic load of the generator unit. Its construction quality directly affects the safe and stable operation and service life of the unit. Turbine generator bases are typically large-volume concrete structures, characterized by large cross-sectional dimensions, high concrete usage, long construction periods, and high technical requirements.

[0003] Curing is a crucial step in concrete construction. The purpose of curing is to retain moisture in the concrete and prevent it from evaporating too quickly, thus ensuring proper hardening and strength development. Improper curing can easily lead to cracks on the concrete surface and insufficient strength, severely impacting the concrete's durability and overall performance.

[0004] Traditional concrete curing methods primarily involve manual watering. While simple and easy to implement, this method also has some limitations: 1. High labor intensity: It requires long hours of manual watering operations, which is labor-intensive and inefficient.

[0005] 2. Uneven maintenance: Manual watering is difficult to ensure uniform maintenance, and localized insufficient maintenance is likely to occur.

[0006] Based on this, we propose an automatic spraying device for the maintenance of steam turbine generator bases. Utility Model Content

[0007] The purpose of this utility model is to improve and innovate upon the shortcomings and problems existing in the background technology, and to provide an automatic spraying device for the maintenance of steam turbine generator base.

[0008] An automatic spraying device for the maintenance of a steam turbine generator base includes a support frame, which consists of columns and connecting beams. A push handle is fixedly connected to the columns of the support frame, and casters are provided at the bottom of the columns. A guide rod is fixedly connected between two columns of the support frame. A first slider and a second slider are slidably fitted on the guide rod. A retaining ring is provided on the guide rod, and a spring is provided between the retaining ring and the first slider. A cam abuts against the second slider, and the cam is driven to rotate by a rotary motor. A spray pipe is located directly below the guide rod and is connected to the outlet of a water pump. A corrugated pipe is provided in the middle of the spray pipe, and atomizing nozzles are spaced apart on the spray pipe. The spray pipe is connected to the first slider and the second slider.

[0009] A further embodiment is that a support rod is fixedly connected to the middle of the push handle, and a caster wheel is also provided at the bottom of the support rod. A second support plate is installed between the support rod and the column of the support frame. The water pump is installed on the second support plate, and a water tank is also provided on the second support plate. The water tank is connected to the water inlet of the water pump.

[0010] A further embodiment is that a screw is threadedly connected to the second support plate, and a support seat is installed at the bottom end of the screw.

[0011] A further embodiment is that the water tank and the water pump are located on opposite sides of the nozzle, and both ends of the nozzle are equipped with corrugated pipes corresponding to the water pump.

[0012] A further embodiment is that the guide rod is fixedly connected to both ends with a fixing sleeve, the inner surface of the fixing sleeve is slidably fitted with the outer surface of the support frame, and the fixing sleeve is fixed to the support frame by fastening bolts.

[0013] A further embodiment is that both the first and second sliders are provided with through grooves adapted to the nozzle, and the lower surfaces of both the first and second sliders are threaded with fastening bolts, which are used to abut against the surface of the nozzle.

[0014] A further option is to provide a push-button switch at the end of the push handle, which is used to control the start and stop of the rotary motor or water pump.

[0015] Compared with the prior art, the beneficial effects of this utility model are: (1) When the rotating screw drives the bottom end of the support seat to separate from the turbine generator base, the staff can hold the push handle to push the maintenance device to move, and thus make it convenient to spray water on the surface of the turbine generator base; when the rotating screw drives the bottom end of the support seat to contact the turbine generator base, the support seat can play a supporting role and prevent the maintenance device from moving. (2) This utility model utilizes the cooperation of a rotary motor, a cam, a first slider, a second slider, a spring, a guide rod, a nozzle, a bellows, and an atomizing nozzle. After the rotary motor drives the cam to rotate, the rotating cam intermittently squeezes the second slider, causing the first slider and the second slider to reciprocate, which in turn drives the atomizing nozzle to reciprocate. At the same time, the water pump delivers water to the atomizing nozzle for spraying, and the water can be evenly sprayed on the turbine generator base, thereby achieving the purpose of curing the turbine generator base without dead angles. This ensures the normal hardening and strength development of the concrete corresponding to the turbine generator base. Attached Figure Description

[0018] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] Please see Figure 1 and Figure 2This utility model provides an automatic spraying device for the maintenance of a steam turbine generator base, including a support frame 1. The support frame 1 consists of columns and connecting beams. Push handles 21 are fixedly connected to two corresponding columns of the support frame 1. Universal wheels 19 are provided at the bottom ends of the columns of the support frame 1. A guide rod 2 is fixedly connected between the two columns of the support frame 1. Specifically, a fixing sleeve 23 is fixedly connected to both ends of the guide rod 2. The inner surface of the fixing sleeve 23 slides against the outer surface of the support frame 1, and the fixing sleeve 23 is fixed to the support frame 1 by fastening bolts. A first slider 5 and a second slider 6 slide against the guide rod 2. A retaining ring 4 is provided on the guide rod 2. A spring 3 is provided between the retaining ring 4 and the first slider 5. The two ends of the spring 3 are fixedly connected to the retaining ring 4 and the first slider 5, respectively. A cam 9 abuts against the second slider 6. The cam 9 is driven to rotate by a rotary motor 8. That is, the cam 9 is installed at the output end of the rotary motor 8. The rotary motor 8 is installed on a first support plate 7, and the first support plate 7 is installed on one of the columns. A nozzle 11 is located directly below the guide rod 2. The nozzle 11 is connected to the outlet of the water pump 13. A corrugated pipe 10 is located in the middle of the nozzle 11. Atomizing nozzles 12 are spaced apart on the nozzle 11, and the nozzle 11 is connected to the first slider 5 and the second slider 6. Therefore, after the rotary motor 8 drives the cam 9 to rotate, the rotating cam 9 will intermittently squeeze the second slider 6, causing the first slider 5 and the second slider 6 to reciprocate, thereby driving the atomizing nozzles 12 to reciprocate. At the same time, the water pump 13 delivers water to the atomizing nozzles 12 for spraying, and the water can be evenly sprayed on the turbine generator base, thereby achieving the purpose of curing the turbine generator base without dead angles; thus ensuring the normal hardening and strength development of the concrete corresponding to the turbine generator base.

[0021] Preferably, a support rod 20 is fixedly connected to the middle of the push handle 21, and a caster wheel 19 is also provided at the bottom of the support rod 20. A second support plate 16 is installed between the support rod 20 and the column of the support frame 1. The water pump 13 is installed on the second support plate 16, and a water tank 14 is also provided on the second support plate 16. A water supply pipe 15 is provided on the water tank 14 for supplying water to the water tank 14. The water tank 14 is connected to the water inlet of the water pump 13. During the reciprocating motion of the atomizing nozzle 12, the water pump 13 simultaneously delivers the water stored in the water tank 14 to the atomizing nozzle 12 for spraying, so that the water can be evenly sprayed on the turbine generator base. The water tank 14 and the water pump 13 are respectively located on both sides of the spray pipe 11, and both ends of the spray pipe 11 are provided with corrugated pipes 10 corresponding to the water pump 13. Once the clean water in one of the water tanks 14 has been sprayed out, the water pump 13 corresponding to the other water tank 14 can be started to spray the clean water from the other water tank 14.

[0022] In some preferred embodiments, a screw 17 is threaded onto the second support plate 16, and a support base 18 is installed at the bottom end of the screw 17. When the screw 17 is rotated, causing the bottom end of the support base 18 to separate from the turbine generator base, the operator can then use the push handle 21 to easily move the maintenance device, thereby facilitating all-around water spraying on the surface of the turbine generator base. When the screw 17 is rotated, causing the bottom end of the support base 18 to contact the turbine generator base, the support base 18 provides support, preventing the maintenance device from moving.

[0023] In order to enable the first slider 5 and the second slider 6 to drive the nozzle 11 to move, the first slider 5 and the second slider 6 are both provided with through grooves adapted to the nozzle 11, and the lower surfaces of the first slider 5 and the second slider 6 are threaded with fastening bolts, which are used to abut against the surface of the nozzle 11.

[0024] Optionally, the push handle 21 is provided with a plurality of push-button switches 22 at its end, which are used to control the start and stop of the rotary motor 8 or the water pump 13. A power cord is also connected to the push-button switch 22, and a plug is provided at the end of the power cord for connecting to the 220V power supply at the turbine generator base.
