[0001] The invention relates to the technical field of hot well sampling, and in particular to a condenser hot well sampling device. Background Art

[0002] In a thermal power plant or a nuclear power plant, the condenser is one of the key equipments.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0038] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0039] Example 1, reference Figure 1-Figure 2 , which is the first embodiment of the present invention, provides a condenser hot well sampling device, including, through the mounting member 103, ensuring that the bubble problem in the sampling process is properly handled, while improving the accuracy and efficiency of sampling.

[0040] Specifically, the mounting assembly 100 includes a condenser hot well body 101, a mounting frame 102 disposed at the bottom of the condenser hot well body 101, and a mounting member 103 for sampling is installed between the mounting frame 102 and the condenser hot well body 101. The mounting member 103 is installed at an angle for bubbles to float.

[0041] Furthermore, the mounting member 103 includes a sampling branch pipe 103a disposed at the end of the swing cylinder 201, and one end of the sampling branch pipe 103a away from the swing cylinder 201 is connected to the mounting pipe 103c of the condenser hot well body 101 through a flange 103b.

[0042] Operation process: Place the condenser hot well body 101 at the desired position. Install the mounting frame 102 at the bottom of the condenser hot well body 101. Install the mounting member 103 between the mounting frame 102 and the condenser hot well body 101, and ensure that the mounting member 103 is installed at an angle so that the bubbles generated during the sampling process can float up smoothly. Connect one end of the sampling branch pipe 103a to the end of the swing cylinder 201. Connect the other end of the sampling branch pipe 103a to the mounting pipe 103c of the condenser hot well body 101 through the flange 103b. When sampling is required, start the swing cylinder 201 to drive the piston block 202 in the sampling branch pipe 103a to move. The piston block 202 moves in the sampling inner tube 203a to extract the liquid in the condenser hot well body 101. The sampling port 203c is designed to have a smooth surface to reduce the generation of vortices, and the design of the guide hole 203d helps to eliminate bubbles, thereby improving the sampling quality and speed. When the piston block 202 moves back to the position of the sampling branch pipe 103a close to the swing cylinder 201, the liquid in the sampling inner tube 203a is discharged through the sampling branch pipe 103a. The inclined installation of the mounting member 103 helps the bubbles to float up, reducing the negative impact of bubbles on the sampling speed and quality. The smooth setting of the sampling port 203c and the design of the guide hole 203d are both for improving the sampling efficiency and quality.

[0043] Example 2, reference Figure 1-Figure 4, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the concave sampling port 203c in the sampling component 200 can effectively reduce the generation of eddy currents, and the sampling port 203c is in a bullet-shaped shape with the top cut off, which can effectively reduce resistance and reduce the generation of bubbles, and the guide hole 203d is used to eliminate eddy currents and bubbles, thereby effectively improving the sampling quality.

[0044] Specifically, the sampling assembly 200 includes a swinging cylinder 201 which is arranged at the end of the mounting member 103 and is used as a sampling power source. A piston block 202 is installed at the end of the piston rod of the swinging cylinder 201. The piston block 202 is located inside the sampling member 203. The sampling member 203 is located at the end of the mounting member 103, and the end of the sampling member 203 extends to the inside of the mounting member 103. The piston block 202 draws the measured liquid into the sampling member 203 through the piston. The side wall of the sampling member 203 is installed with an adjustment member 204 for adjusting the sampling position.

[0045] Furthermore, the sampling member 203 includes a sampling inner tube 203a installed on the inner walls of the mounting tube 103c and the sampling branch tube 103a, and a sampling outer tube 203b is installed between the sampling inner tube 203a and the mounting tube 103c.

[0046] Furthermore, the sampling member 203 also includes a concave sampling port 203c arranged at the ends of the sampling inner tube 203a and the sampling outer tube 203b, and a guide hole 203d for eliminating eddy current is installed inside the sampling port 203c, wherein the sampling port 203c is arranged in a bullet head shape with the top cut off.

[0047] The rest of the structure is the same as that of Example 1.

[0048] Operation process: Start the swing cylinder 201, and the piston block 202 moves in the sampling inner tube 203a. The piston block 202 guides the liquid in the condenser hot well body 101 into the interior of the sampling inner tube 203a through the guide hole 203d in the sampling port 203c through the piston. When the piston block 202 moves back to the position of the sampling branch pipe 103a close to the swing cylinder 201, the liquid in the sampling inner tube 203a is discharged through the sampling branch pipe 103a. Start the swing cylinder 201 to drive the piston block 202 to move to the overflow port 204k near one end of the sampling port 203c. Start the swing cylinder 201 to drive the block 204a in the adjustment member 204 to move into the through groove 204d in the fixed ring 204c, and then rotate into the limit groove 204e. Start the swing cylinder 201 to push the piston ring 204g on the connecting plate 204f to move between the sampling inner tube 203a and the sampling outer tube 203b, and the stopper 204j slides in the sliding groove 204h. Start the swing cylinder 201 again to drive the stopper 204j to rotate and insert into the card slot 204i, pushing the sampling outer tube 203b to move. The piston ring 204g blocks the gap between the sampling inner tube 203a and the sampling outer tube 203b. When the sampling outer tube 203b moves to the sampling position, start the swing cylinder 201 to drive the card block 204a to rotate to the groove 204d and disengage from the fixed ring 204c. Start the swing cylinder 201 again to drive the piston block 202 to extract liquid into the interior of the sampling inner tube 203a. During the long-distance sampling process, close-range sample sampling can also be performed simultaneously, because the swing cylinder 201 drives the piston ring 204g and the sampling outer tube 203b to move forward to expose the overflow port 204k to the outside, and the piston block 202 also moves with the sampling outer tube 203b. The sampling inner tube 203a and the sampling outer tube 203b before the overflow port 204k is close to the sampling port 203c are blocked by the piston ring 204g and the piston block 202, which does not affect the sampling of samples at a distance, and at the same time, the close-range sample can be sampled into the sampling inner tube 203a and flow into the sampling branch pipe 103a through the overflow port 204k. When it is necessary to introduce the sampled sample at a distance into the sampling branch pipe 103a, the sample sampled at a distance will be scraped off during the process of the piston block 202 moving back, and then the sampled sample at a distance is introduced into the sampling branch pipe 103a by the piston block 202.

[0049] Example 3, reference Figure 5-Figure 6 , which is the third embodiment of the present invention. This embodiment is different from the above embodiments in that the adjustment member 204 can be adjusted according to the change of the sampling position to achieve simultaneous collection of samples at close range and long range, thereby improving the efficiency and flexibility of sample collection.

[0050] Specifically, the adjustment member 204 includes a block 204a arranged on the side wall of the piston rod of the swing cylinder 201, a sliding cylinder 204b is installed on the inner wall of the swing cylinder 201, and a fixing ring 204c is installed on the end of the sliding cylinder 204b away from the swing cylinder 201.

[0051] Furthermore, the adjusting member 204 also includes a through groove 204d arranged at the end of the fixing ring 204c and matching with the clamping block 204a and the piston rod of the swing cylinder 201, and a limiting groove 204e is arranged on the inner wall of the fixing ring 204c.

[0052] Furthermore, the adjustment member 204 also includes a connecting plate 204f arranged at the end of the fixed ring 204c, the connecting plate 204f is symmetrically arranged with respect to the central axis of the fixed ring 204c, and the end of the connecting plate 204f away from the fixed ring 204c is connected to the piston ring 204g, and the piston ring 204g matches the spacing between the sampling inner tube 203a and the sampling outer tube 203b.

[0053] Furthermore, the adjustment member 204 also includes a sliding groove 204h arranged between the sampling outer tube 203b and the sampling branch tube 103a, and the inner wall of the sampling outer tube 203b is installed with a clamping groove 204i, which is connected with the sliding groove 204h.

[0054] Furthermore, the adjusting member 204 also includes a stopper 204j disposed on the outer wall of the connecting plate 204f, which is used to push the sampling outer tube 203b to move, and the stopper 204j matches the card slot 204i.

[0055] Furthermore, the adjusting member 204 also includes an overflow port 204k arranged on the side wall of the sampling inner tube 203a. When the overflow port 204k is located between the piston block 202 and the piston ring 204g, it is used to introduce the sampling liquid between the sampling inner tube 203a and the sampling outer tube 203b into the sampling branch tube 103a.

[0056] The rest of the structure is the same as that of Example 2.

[0057] Operation process: First, the sampling branch pipe 103a and the swing cylinder 201 are installed in sequence through the flange 103b, and then the assembled sampling device is installed at the end of the installation pipe 103c on the side wall of the condenser hot well body 101, and the installation component 100 is installed at an angle to facilitate the floating of bubbles generated during the sampling process, thereby reducing the obstruction of bubbles to the sampling speed and quality;

[0058] When it is necessary to sample the liquid at a close distance, the swing cylinder 201 is started, and the swing cylinder 201 drives the piston block 202 to move in the sampling inner tube 203a, and then the piston block 202 drives the liquid in the condenser hot well body 101 to be introduced into the interior of the sampling inner tube 203a through the guide hole 203d in the sampling port 203c. The sampling port 203c is smoothly arranged to reduce the generation of eddy currents, and the guide hole 203d is arranged to eliminate bubbles during the extraction process and reduce the influence of bubbles on the sampling work. When the piston block 202 moves to the sampling branch tube 103a close to the swing cylinder 201 during the process of moving back, the liquid in the sampling inner tube 203a is directly discharged through the sampling branch tube 103a;

[0059] When sampling is required at a long distance, the swing cylinder 201 is started to drive the piston block 202 to move to the overflow port 204k near the end of the sampling port 203c, and the swing cylinder 201 is started to drive the block 204a to move into the through groove 204d in the fixed ring 204c, wherein the interior of the fixed ring 204c is semi-hollow, and the two sides of the central axis of the through groove 204d add up to 90 degrees to form a limit groove 204e, and then the swing cylinder 201 is started to drive the block 204a to rotate and move into the limit groove 204e, thereby starting the swing cylinder 201 to push the piston ring 204g on the connecting plate 204f to move into the sampling inner The piston ring 204g of the cylinder 204a is used to block the gap between the inner tube 203a and the outer tube 203b. When the outer tube 203b is moved to the sampling position, the cylinder 201 is started again to drive the block 204j on the fixed ring 204c to rotate and insert into the inner groove 204i to push the outer tube 203b to move. The groove 204i is only set on the side wall of the sliding groove 204h, and the block 204j is just inserted into the inner groove 204i set on one side when rotating. The piston ring 204g blocks the gap between the inner tube 203a and the outer tube 203b. When the outer tube 203b moves to the sampling position, the cylinder 201 is started again to drive the block 204j on the fixed ring 204c to rotate and insert into the inner groove 204i to push the outer tube 203b to move. After the swing cylinder 201 drives the block 204a to rotate to the groove 204d and disengage from the fixed ring 204c, the swing cylinder 201 is started again to drive the piston block 202 to extract the liquid into the interior of the sampling inner tube 203a. In the process of long-distance sampling, close-range sampling can also be performed at the same time, because the swing cylinder 201 drives the piston ring 204g and the sampling outer tube 203b to move forward to expose the overflow port 204k to the outside, and the piston block 202 also moves with the sampling outer tube 203b. Therefore, the sampling inner tube before the overflow port 204k is close to the sampling port 203c is opened by the piston ring 204g and the piston block 202. 203a and the sampling outer tube 203b are blocked, so the sampling of samples at a distance is not affected. At the same time, the samples at a short distance can be sampled into the sampling inner tube 203a and flow into the sampling branch tube 103a through the overflow port 204k. When the sampling samples at a distance need to be introduced into the sampling branch tube 103a, the samples sampled at a short distance will be scraped off during the return movement of the piston block 202, and then the sampling samples at a long distance will be introduced into the sampling branch tube 103a through the piston block 202, so that the device can change according to the sampling position, and can collect samples at a short distance and a long distance at the same time, thereby improving the sample collection efficiency.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
