Description

Technical Field

[0001] The utility model relates to the technical field of the temperature of an indirect cooling tower, in particular to an installation mechanism and an indirect cooling tower temperature detection device. Background Art

[0002] An indirect cooling tower is a cooling tower in an indirect air cooling system and is a device for industrial cooling.

[0003] In the indirect air cooling system of an indirect cooling tower, the exhaust steam generated during the power generation process of a steam turbine is first introduced into a condenser. After the cooling water absorbs the heat of the exhaust steam, its temperature rises, and then it is transported to the radiator in the cooling tower, that is, an air-cooled tube bundle or a cooling triangle. These radiators are vertically arranged at the bottom of the cooling tower, and heat exchange is carried out between the hot water flowing inside the finned tube bundle and the air flowing outside the tube bundle, so as to realize the cooling of the cooling water.

[0004] Temperature detection elements are usually arranged on the finned tube bundle. The temperature detection elements are usually temperature sensors, which measure the temperature measurement points on the finned tube bundle and are connected to the DCS system to complete the dynamic monitoring of the temperature data at the bottom of the indirect cooling tower. The temperature sensor is generally fixed by fitting on the surface of the finned tube bundle, and the fixing method on the finned tube bundle is welding fixation, bolt fixation and flange fixation. However, when installing and regularly disassembling and replacing the temperature sensor, this fixing method causes scratches, deformation or other physical damages to the surface of the finned tube bundle and the temperature sensor, increasing the risk of leakage and other failures of the finned tube bundle. Moreover, it will affect the stability of the temperature sensor here, resulting in inaccurate temperature monitoring data at the temperature measurement point. Summary of the Utility Model

[0042] Embodiment 1

[0043] Referring to Figure 1 - Figure 3 , which is the first embodiment of the present utility model, provides an installation mechanism. This device includes

[0044] The installation unit 100 includes an installation base 101, an installation groove 102 provided on the installation base 101, and an auxiliary component 103 provided on one side of the installation groove 102; the installation base 101 is a carrier of the contraction component 203 in the contraction unit 200.

[0045] The contraction unit 200 includes a driving contraction ring 201 rotatably provided at one end of the installation base 101, a driven contraction ring 202 rotatably provided at the other end of the installation base 101, and a contraction component 203 provided on the driving contraction ring 201; and, the fixing unit 300 includes a sliding groove 301 provided on the driving contraction ring 201, a sliding plate 302 slidably provided in the sliding groove 301, and a fixing component 303 provided on the sliding plate 302. By the coordinated use of the contraction component 203, the fixing component 303, and the auxiliary component 103, the hard friction directly on the surface of the fin 402a tube bundle 401 can be avoided, and the risk of physical damage to the surface of the fin 402a tube bundle 401 can be reduced.

[0046] Among them, the auxiliary component 103 includes a telescopic column 103a provided on the installation base 101, a telescopic sleeve 103b slidably provided on the telescopic column 103a, and a heat conducting sheet 103c provided on the telescopic sleeve 103b; a limiting groove 103d is provided on the heat conducting sheet 103c. The telescopic column 103a on the installation base 101 slides in the telescopic sleeve 103b, which can adjust the distance between the heat conducting sheet 103c and the installation base 101. The heat conducting sheet 103c is made of a deformable material and the material is relatively soft, which can adjust the arc according to the arc of the tube bundle 401 to adapt to different tube bundles 401, increasing the flexibility and applicability of the heat conducting sheet 103c during the process of conducting temperature.

[0047] Among them, the fixing component 303 includes a connecting plate 303a rotatably arranged on the sliding plate 302, an arc-shaped member 303b arranged on the connecting plate 303a, an elastic strip 303c arranged on the arc-shaped member 303b, and a soft pad 303d arranged on the elastic strip 303c. The connecting plate 303a is rotatably connected to the sliding plate 302, that is, the connecting plate 303a can be arbitrarily adjusted in angle on the sliding plate 302 within the range not blocked by the active contraction ring 201 and the driven contraction ring 202. The materials of the arc-shaped member 303b and the soft pad 303d are deformable. The elastic band is used to support the soft pad 303d for buffering, reducing the physical stress on the surface of the tube bundle 401. The soft pad 303d fits on the surface of the tube bundle 401 to prevent physical damage to the surface of the tube bundle 401 caused by rigid fixing and clamping.

[0048] During the use process, first, the installer will adjust the shape of the heat conducting sheet 103c according to the outer arc of the tube bundle 401 to make the heat conducting sheet 103c completely fit on the surface of the tube bundle 401, increasing the contact area for the heat conducting sheet 103c to conduct temperature. The increase in the contact area between the heat conducting sheet 103c and the surface of the tube bundle 401 can improve the efficiency of heat conduction, enabling heat to be transferred from the tube bundle 401 to the heat conducting sheet 103c faster. The increase in the contact area can reduce the thermal resistance, that is, the resistance encountered by heat during the transfer process, thereby improving the overall temperature conduction performance of the heat conducting sheet 103c.

[0049] Secondly, adjust the angle of the connecting plate 303a on the slider so that the soft pad 303d can fit around the tube bundle 401 for subsequent operations of clamping and fixing the tube bundle 401. During the adjustment process, the slider will move in the active contraction ring 201 and the driven contraction ring 202. Coupled with the fact that the connecting plate 303a can adjust the angle on the slider, the arc-shaped member 303b and the soft pad 303d can adapt to tube bundles 401 of different calibers, increasing the versatility and flexible practicality of the fixing component 303. The soft pad 303d fits tightly around the tube bundle 401, providing uniform clamping force to ensure that the tube bundle 401 will not displace or rotate during the fixing process. The use of the soft pad 303d prevents physical damage to the surface of the tube bundle 401 caused by rigid fixing and clamping, reducing the possibility of failures caused by physical damage to the surface of the tube bundle 401. Moreover, the movement of the slider in the active contraction ring 201 and the driven contraction ring 202, as well as the adjustment of the angle of the connecting plate 303a, make the entire fixing process simpler and faster.

[0050] Embodiment 2

[0051] Refer to Figure 1 - Figure 5, which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that the contraction assembly 203 includes a support base 203a disposed on the active contraction ring 201, a nut 203b disposed on the support base 203a, and a bolt 203c rotatably disposed in the nut 203b. The support base 203a is used to support the operation of the bolt 203c and the nut 203b. The bolt 203c rotates in the nut 203b and the support base 203a, driving the rotation of the support column 203g.

[0052] Compared with Embodiment 1, further, a chute 301 is provided on the driven contraction ring 202, and a positioning hole 203d is provided on the driven contraction ring 202. The chute 301 on the driven contraction ring 202 is the same as the chute 301 on the active contraction ring 201, both providing space for the sliding of the slider. The positioning member 203h moves in the positioning hole 203d, which can reduce the diameter of the circle formed by the active contraction ring 201 and the driven contraction ring 202, thereby shrinking and fixing the fixing assembly 303 on the surface of the tube bundle 401 and preventing the fixing assembly 303 from falling off the surface of the tube bundle 401.

[0053] Among them, the contraction assembly 203 further includes a positioning groove 203e provided on the bolt 203c, a clamping block 203f movably disposed on the positioning groove 203e, a support column 203g provided on the clamping block 203f, and a positioning member 203h provided on the support column 203g. The support column 203g is driven to rotate by the rotation of the bolt 203c. The clamping block 203f at one end of the fixed column moves in the positioning groove 203e. When the bolt 203c rotates in the nut 203b, the fixed column will not shorten or extend the distance within the support base 203a due to the rotation of the bolt 203c.

[0054] During use, after the operator adjusts the angles of the heat conducting fins 103c and the arc-shaped plate on the surface of the tube bundle 401, the bolt 203c on the support base 203a is rotated. The positioning member 203h at one end of the fixed column moves in the positioning hole 203d on the driven contraction ring 202. The driven contraction ring 202 with the positioning hole 203d is made of a soft material. The rotation of the positioning member 203h drives the uniform contraction of the driven contraction ring 202 in the active contraction ring 201, reducing the diameter of the circle formed by the active contraction ring 201 and the driven contraction ring 202, thereby shrinking and fixing the fixing assembly 303 on the surface of the tube bundle 401.

[0055] By controlling the position of the positioning member 203h through the rotation of the bolt 203c, the adjustment of the driven contraction ring 202 is realized, ensuring the tight fit between the fixing assembly 303 and the tube bundle 401. The uniform contraction of the driven contraction ring 202 can ensure uniform force on the surface of the tube bundle 401, avoid local stress concentration, and reduce the risk of damage to the surface of the tube bundle 401.

[0056] The remaining structure is the same as that of Embodiment 1.

[0057] Embodiment 3

[0058] Refer to Figure 1 - Figure 8 , which is the third embodiment of the present utility model. The difference between this embodiment and the second embodiment is: An indirect cooling tower temperature detection device includes,

[0059] A heat dissipation unit 400, including a tube bundle 401 disposed on a fixing component 303, and a heat dissipation component 402 disposed on the tube bundle 401; and,

[0060] A detection unit 500, including a temperature sensor 501 disposed on the installation groove 102, and a transmission component 502 disposed on the installation base 101. The main purpose of the heat dissipation unit 400 is to dissipate the heat generated inside the indirect cooling tower and keep the system operating at a safe working temperature. During the operation of the indirect cooling tower, operators will add temperature detection points at the heat dissipation unit 400 to complete the dynamic detection of the bottom temperature of the indirect cooling tower, obtain temperature data, and provide data support for the overall data and optimized operation of the component indirect cooling tower. The detection unit 500 cooperates with the installation unit 100, the contraction unit 200, and the fixing unit 300 to increase the stability of the temperature sensor 501 at the temperature detection point and improve the accuracy of the temperature data detected by the temperature sensor 501 at the detection point of the temperature sensor 501.

[0061] Compared with Embodiment 2, further, the transmission component 502 includes a fixing sleeve 502a disposed on the installation base 101, and a data sensing wire 502b disposed on the fixing sleeve 502a. The fixing sleeve 502a is used to fix the data sensing wire 502b, and the data sensing wire 502b is used to transmit the temperature data detected by the temperature sensor 501 to the data collection module.

[0062] Wherein, the heat dissipation component 402 includes fins 402a disposed on the tube bundle 401, and a connecting pipe 402b disposed on the tube bundle 401; the fins 402a are arranged in a linear array on the tube bundle 401, and the diameter of the connecting pipe 402b is larger than the diameter of the tube bundle 401. It mainly dissipates the heat generated inside the indirect cooling tower. The presence of the fins 402a improves the dynamic characteristics of air flow and increases the convective heat exchange between the air and the pipe surface.

[0063] Among them, a transfer pipe 402c is provided on the connecting pipe 402b, and the tube bundles 401 are arranged on the transfer pipe 402c at equal intervals. A flange 402d is provided on the transfer pipe 402c, and mounting holes 402e are provided on the flange 402d. The flange 402d and the mounting holes 402e on the flange 402d are used to connect the transfer pipe 402c with other liquid transfer components. The transfer pipe 402c transfers the working liquid into the tube bundles 401. By adding fins 402a outside the pipeline, the tube bundles 401 significantly increase the surface area of the pipeline, thereby providing a larger heat exchange area.

[0064] During the use process, the operator will not first adjust the driven shrinkage ring 202 to the optimal fixing degree on the active shrinkage ring 201. Instead, the arc-shaped part 303b will first be adjusted to fit the surface of the tube bundle 401 according to the surface curvature of the tube bundle 401 for micro-fixing, that is, not complete fixing. By first performing micro-fixing instead of immediately complete fixing, the operator can gradually ensure the degree of fit between the arc-shaped part 303b and the surface of the tube bundle 401, avoiding readjustment caused by improper initial fixing. At this time, the operator will install the temperature sensor 501 in the installation groove 102 on the installation base 101, and the other end of the temperature sensor 501 is fixed in the limit groove 103d on the heat conduction sheet 103c, thereby increasing the stability of the temperature sensor 501 during the installation process.

[0065] Since the slider can slide in the chute 301 and the telescopic column 103a can move in the telescopic sleeve 103b, the auxiliary component 103 can cooperate with the installation groove 102 to improve the convenience of installing the temperature sensor 501. After the temperature sensor 501 is installed, the operator continues to adjust the rotation of the bolt 203c to adjust the driven telescopic ring to the optimal tightening state on the active telescopic ring, maintaining the stability of the temperature sensor 501 during the detection process and improving the accuracy of the temperature detection point data.

[0066] The remaining structure is the same as that of Embodiment 2.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
