Description

Technical Field

[0001] The utility model belongs to the technical field of condensate pump maintenance, and in particular relates to a refueling auxiliary device for a condensate pump. Background Art

[0002] In each steam turbine unit of a power plant, in order to maintain the vacuum pressure in the steam turbine condenser within the specified parameter range, a condensate pump is required to promptly remove the water condensed in the condenser by the exhaust steam of the last stage of the steam turbine, so that the water level of the hot well is maintained within the specified height range. During the long-term operation of the condensate pump, the lubricating oil of the condensate pump will be reduced due to the operating conditions and the environment in which it is located. Severe oil shortage will affect the normal operation of the condensate pump, and the pump will not be able to remove the condensate in time, causing the vacuum of the unit to drop or even shut down, posing a threat to the safe operation of the power plant. Regular oiling and maintenance of the condensate pump is essential.

[0003] In conventional refueling operations, operators will use a funnel to refuel the running condensate pump. Ordinary funnels are light in weight and cannot fit well with the oil filling hole of the condensate pump. The wind pressure generated when the condensate pump is running can easily blow over the funnel. Therefore, at least two people are required to cooperate in the refueling operation, one to support and fix the funnel, and the other to pour the oil. Not only does it increase the labor intensity, but it is also very easy for lubricating oil to overflow due to improper cooperation, resulting in waste of lubricating oil and pollution to the condensate pump and the surrounding environment.

[0004] Therefore, there is a need for a convenient and quick refueling auxiliary device for a condensate pump that can effectively reduce the risk of lubricating oil spillage. Utility Model Content

[0005] The utility model aims to provide a refueling auxiliary device for a condensate pump, which is convenient and quick to operate, can effectively reduce the risk of lubricating oil spillage, achieve energy saving and environmental protection while reducing labor intensity.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] An auxiliary refueling device for a condensate pump comprises an oil reservoir with an opening at the top and a flip cover, an oil guide pipe connected to an oil outlet opened at the bottom of the oil reservoir and adapted to the oil filling hole of the condensate pump, and a blocking column horizontally penetrating a side wall of the oil reservoir and moving radially to open or close the oil outlet.

[0008] A further improvement of the technical solution of the utility model is that the interior of the blocking column is hollow and is provided with an adjusting mechanism, one end of the blocking column extending into the oil reservoir is symmetrically provided with elastic stoppers that respectively penetrate the side walls on both sides thereof, and the other end is provided with a positioning plate, and the two elastic stoppers are controlled by the adjusting mechanism to move relative to each other on the blocking column to extend or retract.

[0009] A further improvement of the technical solution of the utility model is that mounting holes with sliding grooves are symmetrically opened on the side walls on both sides of one end of the blocking column, and the elastic stopper includes a block slidably connected to the mounting hole of the blocking column and a return spring symmetrically arranged on both sides of the block, one end of the return spring is connected to the top of the block, and the other end thereof is connected to the outer wall of the blocking column.

[0010] A further improvement of the technical solution of the utility model is that the adjustment mechanism is an adjustment rod which horizontally penetrates the positioning plate and moves axially inside the blocking column. The end of the adjustment rod extending into the blocking column gradually shrinks in diameter to form a cone which is adapted to the two blocks. A limiting plate is provided at the other end, and a clamping piece which is adapted to the limiting plate is provided on the positioning plate.

[0011] A further improvement of the technical solution of the utility model is that the end faces of the two blocks at the opposite ends are both arc-shaped surfaces. When the two blocks are retracted into the blocking column, the diameter size of the virtual circle where the two arc-shaped surfaces are located is adapted to the minimum diameter of the frustum.

[0012] A further improvement of the technical solution of the utility model is that the clamping member is located on one side of the limiting plate, and includes a rotating shaft arranged on the positioning plate and a blocking piece rotatably arranged on the rotating shaft, and the distance between the blocking piece and the positioning plate is adapted to the thickness of the limiting plate.

[0013] A further improvement of the technical solution of the utility model is that the body of the blocking column is a rectangular parallelepiped structure with an outer wall covered with a rubber layer, and its width is greater than the diameter of the oil outlet.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by the utility model is:

[0015] The utility model is used for the refueling auxiliary device of the condensate pump, which is convenient and quick to operate, can effectively reduce the risk of lubricating oil spillage, achieves energy saving and environmental protection, can effectively reduce labor intensity, and is more convenient during maintenance.

[0016] The utility model adopts the cooperation of an oil reservoir, an oil guide pipe and a blocking column, which can conveniently and quickly refuel the condensate pump; the oil guide pipe is adapted to the oil filling hole of the condensate pump, and when the oil reservoir is inserted into the oil filling hole of the condensate pump through the oil guide pipe for oil filling, it can effectively prevent the oil inside the oil reservoir from overflowing and prevent the oil from being wasted; the blocking column horizontally penetrates one side wall of the oil reservoir and moves along its radial direction to open or close the oil outlet, and the release and blocking of the oil in the oil reservoir can be effectively controlled by the blocking column, the operation is convenient, and the labor intensity is effectively reduced.

DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with the embodiments:

[0023] like Figure 1As shown, the utility model provides a refueling auxiliary device for a condensate pump, comprising an oil reservoir 1, an oil guide pipe 4 and a blocking column 5. The oil reservoir 1 is a cylindrical container with an opening at the top and provided with scale lines. A handle is provided on one side wall of the oil reservoir 1, and a flip cover 2 is provided at the top opening. The flip cover 2 is hinged to the side wall of the oil reservoir 1 through a pin shaft. An oil outlet 3 is provided at the bottom of the oil reservoir 1. Preferably, the oil outlet 3 is arranged at the bottom center of the oil reservoir 1, and the oil guide pipe 4 is connected to the oil reservoir 1 through the oil outlet 3, and the oil guide pipe 4 is adapted to the oil filling hole of the condensate pump, that is, the diameter size of the oil guide pipe 4 is adapted to the oil filling hole. Since the oil guide pipe 4 has a certain length, when the oil reservoir 1 is inserted into the oil filling hole of the condensate pump through the oil guide pipe 4 for oil filling, it can effectively avoid The oil inside the oil reservoir 1 overflows and is prevented from being wasted. The blocking column 5 horizontally penetrates the side wall of the oil reservoir 1 near the bottom, that is, a hole adapted to the blocking column 5 is opened on the side wall of the oil reservoir 1 near the bottom. The blocking column 5 can move radially along the oil reservoir 1 through the hole. The oil outlet 3 is opened or closed by pulling or pushing the blocking column 5, thereby achieving the purpose of releasing or blocking the oil in the oil reservoir 1. The column body of the blocking column 5 is a rectangular structure with a rubber layer coated on the outer wall. The width of the blocking column 5 is greater than the diameter of the oil outlet 3 to ensure that the oil outlet 3 can be completely covered. The oil outlet 3 can be set to a circular shape or a rectangular shape adapted to the blocking column 5.

[0024] During operation, when oil is stored in the oil reservoir 1, the blocking column 5 is pushed and moved along the radial direction of the oil reservoir 1 to completely seal the oil outlet 3 and add oil into the oil reservoir 1; when the oil reservoir 1 is used to fill oil into the condensate pump, the blocking column 5 is pulled and moved along the radial direction of the oil reservoir 1 to open the oil outlet 3 so that the oil inside can flow into the condensate pump through the oil guide pipe 4. In this process, the amount of oil filled can be judged by observing the scale lines on the oil reservoir 1; when the condensate pump is filled with oil, the blocking column 5 is pushed and moved along the radial direction of the oil reservoir 1 again to completely seal the oil outlet 3 in preparation for the next oil filling.

[0025] In order to ensure the sealing performance of the oil reservoir 1 when it is storing oil and prevent the sealing column 5 from falling out of the hole on the side wall of the oil reservoir 1 when it is filled with oil, the sealing column 5 is hollow inside and an adjusting mechanism is arranged inside it. Elastic stoppers 7 are symmetrically arranged on one end of the sealing column 5 extending into the oil reservoir 1. The two elastic stoppers 7 respectively penetrate the side walls of the sealing column 5 on both sides. A positioning plate 6 is arranged on the other end of the sealing column 5, and the diameter of the positioning plate 6 is larger than the column diameter of the sealing column 5. The two elastic stoppers 7 are controlled by the adjusting mechanism to realize relative movement, extension or retraction on the sealing column 5.

[0026] When the two elastic stoppers 7 are controlled by the adjusting mechanism to move relative to each other on the blocking column 5 and extend out, the two elastic stoppers 7 can limit the end of the blocking column 5 extending into the oil reservoir 1 within the oil reservoir 1. When the two elastic stoppers 7 are controlled by the adjusting mechanism to move relative to each other on the blocking column 5 and retract, the blocking column 5 can be quickly installed on or removed from the oil reservoir 1, which is conducive to cleaning and maintenance thereof.

[0027] Specifically, Figure 2 and Figure 3 As shown, mounting holes are symmetrically provided on the side walls on both sides of one end of the blocking column 5 extending into the oil reservoir 1, and sliding grooves are symmetrically arranged on the left and right sides of the mounting hole. The elastic stopper 7 includes a block 7-1 and two return springs 7-2. The left and right sides of the block 7-1 are provided with sliding strips adapted to the sliding grooves of the mounting hole, so as to realize the sliding connection between the block 7-1 and the mounting hole on the blocking column 5. The two return springs 7-2 are symmetrically arranged on both sides of the block 7-1. Preferably, the two return springs 7-2 are symmetrically arranged on the upper and lower sides of the block 7-1, one end of the return spring 7-2 is connected to the top of the block 7-1, and the other end thereof is connected to the outer wall of the blocking column 5.

[0028] The adjusting mechanism is a cylindrical adjusting rod 8, which horizontally penetrates the positioning plate 6 and can move along the axial direction in the blocking column 5. The end of the adjusting rod 8 extending into the blocking column 5 gradually shrinks in diameter to form a cone 8-1. The cone 8-1 is adapted to the two blocks 7-1, that is, the end faces of the two blocks 7-1 at the opposite ends are both arc-shaped surfaces. When the two blocks 7-1 are retracted into the blocking column 5, the diameter of the virtual circle where the two arc-shaped surfaces are located is adapted to the minimum diameter of the cone 8-1.

[0029] In order to facilitate the limiting of the adjusting rod 8, a limiting plate 8-2 is set at the other end of the adjusting rod 8. The diameter of the limiting plate 8-2 is smaller than the positioning plate 6 and larger than the rod body diameter of the adjusting rod 8. The positioning plate 6 is provided with a clamping member 9 adapted to the limiting plate 8-2. The clamping member 9 is located on one side of the limiting plate 8-2, and includes a rotating shaft 9-1 set on the positioning plate 6 and a baffle 9-2 rotatably set on the rotating shaft 9-1. The distance between the baffle 9-2 and the positioning plate 6 is adapted to the thickness of the limiting plate 8-2.

[0030] When using the oiling auxiliary device to fill the condensate pump with oil, the following steps are included:

[0031] Step S1: inserting one end of the blocking column 5 into the oil reservoir 1;

[0032] Step S2: Control the adjusting rod 8 to move in the axial direction of the blocking column 5, so that the cone 8-1 at its end gradually pushes open the two blocks 7-1 on the blocking column 5, and the two blocks 7-1 are relatively moved and extended in the mounting hole of the blocking column 5 under the action of the cone 8-1, so that the end of the blocking column 5 extending into the oil reservoir 1 is restricted in the oil reservoir 1;

[0033] Step S3: Rotate the baffle 9-2 on the positioning plate 6 to the limiting plate 8-2 of the adjusting rod 8 to limit the adjusting rod 8 so that the two clamping blocks 7-1 are always kept at a position where the two blocking blocks 7-1 can extend on the blocking column 5, thereby effectively preventing the blocking column 5 from falling out of the oil reservoir 1 when moving back and forth;

[0034] Step S4: Control the blocking column 5 to move along the radial direction of the oil reservoir 1 so as to completely seal the oil outlet 3, and open the flip cover 2 on the top of the oil reservoir 1 to inject oil into the oil reservoir 1;

[0035] Step S5: insert the oil reservoir 1 into the oil filling hole of the condensate pump through the oil guide pipe 4, and control the blocking column 5 to move along the radial direction of the oil reservoir 1, open the oil outlet 3 to allow the oil inside the oil reservoir 1 to flow into the condensate pump through the oil guide pipe 4, and in this process, the amount of oil filling can be judged by observing the scale line on the oil reservoir 1;

[0036] Step S6: After the condensate pump is filled with oil, the blocking column 5 is moved again along the radial direction of the oil reservoir 1 to completely seal the oil outlet 3 in preparation for the next oil filling.

[0037] When it is necessary to clean and maintain the refueling auxiliary device, the baffle 9-2 on the rotatable positioning plate 6 can release the limit on the adjusting rod 8, and the adjusting rod 8 can be controlled to be pulled and moved along its axial direction in the blocking column 5, so that the cone 8-1 at its end gradually moves away from the two blocks 7-1 on the blocking column 5 until the two blocks 7-1 are relatively moved and retracted in the mounting hole of the blocking column 5 under the action of the reset spring 7-2, and then the blocking column 5 is taken out of the oil reservoir 1, and the blocking column 5 and the oil reservoir 1 are cleaned and maintained respectively.

[0038] The utility model is used for the refueling auxiliary device of the condensate pump, which is convenient and quick to operate, can effectively reduce the risk of lubricating oil spillage, achieves energy saving and environmental protection, can effectively reduce labor intensity, and is more convenient during maintenance.
