[0032] This utility model discloses a colorimetric card comparison device for measuring suspended matter in nuclear power plants. The colorimetric card comparison device for measuring suspended matter in nuclear power plants includes a housing 1, a color card mounting base, and an operating mechanism.
[0033] The housing 1 has a cavity for accommodating the color card mounting base and part of the operating mechanism, while reserving space for the color card mounting base to rotate and / or reciprocate. An observation window 2 communicating with the cavity is provided on one side of the housing 1. The size of the observation window 2 is basically consistent with the shape and size of the standard color card. The color card mounting base is reciprocally movable in the cavity so that the standard color cards on the color card mounting base can pass through the observation window 2 one by one. The operating mechanism is connected to the color card mounting base to drive the color card mounting base to reciprocate.
[0034] Compared with the prior art, the nuclear power plant suspended solids measurement colorimetric card comparison device provided in this application installs multiple standard color cards on the color card mounting base. By moving the color card mounting base, each standard color card can pass through the observation window 2 and be compared with the wastewater sample, thereby facilitating and quickly finding the standard color card and improving sampling and testing efficiency.
[0035] The color card mounting base can be reciprocated within the housing 1 in various ways, such as... Figures 1 to 5 As shown, a central shaft 4 is provided inside the housing 1. The central shaft 4 is coaxial with the housing 1 and can rotate relative to the housing 1. At least one end of the central shaft 4 extends out of the housing 1 and is connected to a handwheel 5 so that the user can operate the central shaft 4. The color card mounting base is reciprocally movable on the central shaft 4.
[0036] In addition to rotation, in order to increase the capacity of the standard color card, in an embodiment of the present application, the central shaft 4 is arranged in the shell 1 in an axially reciprocating manner, so that the central shaft 4 can not only rotate relative to the shell 1, but also reciprocate axially relative to the central shaft 4. Through movement in multiple directions, the color card mounting seat can be provided with a larger number of standard color cards, such as Figure 6 and Figure 7 As shown, the central shaft 4 can drive the color card mounting seat to move left or right relative to the shell 1.
[0037] Specifically, the color card mounting seat includes a sleeve part 8 and a plurality of color card wheels 7, the sleeve part 8 is sleeved on the central shaft 4, and the color card wheels 7 are coaxially arranged with the sleeve part 8. Each color card wheel 7 is arranged in an axial direction of the central shaft 4, and a plurality of standard color cards are arranged in a circumferential direction of the color card wheel 7. In this way, the user can align different standard color cards with the observation window 2 by axially moving the central shaft 4 and rotating the central shaft 4, so that the color card mounting seat can be provided with more types of standard color cards.
[0038] As shown in Figure 4 In an embodiment of the present application, the cross section of the color card wheel 7 is circular or polygonal, and the polygonal shape includes but is not limited to triangle, square, regular pentagon, regular hexagon, regular heptagon, regular octagon, regular nonagon, etc.
[0039] In order to keep the standard color card stable during detection, in an embodiment of the present application, the central shaft 4 includes a rotation-stopping cooperation part and a rotation cooperation part arranged in sequence in an axial direction, and the color card mounting seat can cooperate with the rotation-stopping cooperation part and the rotation cooperation part, respectively. The color card mounting seat cooperates with the rotation-stopping cooperation part to make the color card mounting seat relatively stationary with the central shaft 4, and the color card mounting seat cooperates with the rotation cooperation part to make the color card mounting seat freely rotate relative to the central shaft 4. When it is necessary to fix the color card mounting seat, the color card mounting seat cooperates with the rotation-stopping cooperation part, and when it is necessary to rotate the color card mounting seat to find the required standard color card, the color card mounting seat cooperates with the rotation cooperation part.
[0040] Specifically, the rotation-stopping cooperation part includes a key structure arranged on the central shaft 4, and a groove structure arranged on the side wall of the through hole of the color card mounting seat for the central shaft 4 to pass through, and the rotation cooperation part is a light rod structure. In this way, by sliding the color card mounting seat in a circumferential direction of the central shaft 4, the color card mounting seat can be switched between cooperating with the rotation-stopping cooperation part and cooperating with the rotation cooperation part, which is convenient to operate.
[0041] As shown in Figure 1 Both ends of the central shaft 4 pass out of the shell 1, and each end of the central shaft 4 is provided with a limiting stopper, which cooperates with the shell 1 to avoid the central shaft 4 from being separated from the shell 1.
[0042] As shown in Figure 2As shown in the embodiment of the present application, the housing 1 is provided with an operation opening 6 extending along the moving direction of the color card mounting seat, and the operation mechanism is an operation handle 3 connected to the color card mounting seat, one end of the operation handle 3 being connected to the sleeve part 8, and the other end extending out of the operation opening 6.
[0043] Further optimization of the above technical solutions, such as Figure 2 As shown in the above operation opening 6, the operation opening 6 includes a moving groove part 601 extending along the moving direction of the color card mounting seat, and a plurality of limiting groove parts 602 spaced apart from the moving groove part 601 along the moving direction of the color card mounting seat, the center distance between two adjacent limiting groove parts 602 being equal to the center distance between two adjacent color cards, so that the operation handle 3 can be clamped into the limiting groove part 602 to limit the operation handle 3 during comparison or carrying.
[0044] As a preferred, at least one side groove wall of the end of the limiting groove part 602 away from the moving groove part 601 is provided with a clamping protrusion to form a clamping limiting part with a closed structure in the limiting groove part 602, when the operation handle 3 moves along the limiting groove part 602 to contact the clamping protrusion, the operation handle 3 and / or the clamping protrusion are elastically deformed, so that the operation handle 3 can enter the clamping limiting part, thereby limiting the operation handle 3.
