Description

Technical Field

[0001] The invention relates to the technical field of thermal power plants, in particular to a cooling water pipe fixing device for a thermal power plant. Background Art

[0002] The high-temperature gas generated by burning fuel in a thermal power plant is converted into high-temperature steam after passing through the heat exchanger in the boiler. The steam drives the steam turbine to rotate and generate electricity. In this process, a large amount of cooling water is needed to cool equipment such as generators, steam turbines and boilers to control the temperature of the equipment and ensure the normal operation of the equipment. Therefore, cooling water pipes need to be laid for the transportation of cooling water.

[0003] During use, when cooling water passes through the cooling water pipe, it will cause a certain displacement of the pipe. This displacement is usually called pipe vibration or pipe movement. Pipe vibration is caused by the dynamic effect of water flowing through the pipe. When water flows through the pipe, the inertia and pressure of the fluid will exert force on the pipe wall, causing vibration and displacement of the pipe, causing friction between the pipe side wall and the fixture, affecting the service life of the fixture.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] Example 1

[0031] Reference Figures 1 to 4 , which is the first embodiment of the present invention, provides a cooling water pipe fixing device for a thermal power plant, which can achieve the effect of avoiding friction between the pipe and the fixing device, and comprises a fixing component 100, the pipe is installed at a desired position, comprises a base 101, a telescopic component 102 movably connected to the base 101, a height-adjustable fixing component 100, and a mounting component 103 fixed to the telescopic component 102, the pipe is arranged on the mounting component 103, and

[0032] The buffer component can extend the service life of the fixing device, including a support component 201 fixedly connected to the installation component 103, a limit component 202 movably connected to the support component 201 so that the support component 201 can rotate, a limit component 202 movably connected to the support component 201, the limit component 202 fits against the side wall of the pipeline, an extrusion component 203 arranged above the limit component 202, the extrusion component 203 can control the clamping component 204, the clamping component 204 movably connected to the extrusion component 203, the clamping component 204 can control the contraction state of the sliding component 205, and the sliding component 205 movably connected to the clamping component 204. When the pipeline moves on the fixing device, the sliding component 205 can reduce the friction between the side wall of the pipeline and the fixing device.

[0033] In summary, after the operator installs the pipe on the fixed component 100, the device uses the limiting component 202 on the supporting component 201 to fit with the side wall of the pipe. When the cooling water passes through the pipe, the inertia drives the pipe to move forward, the side wall of the pipe fits with the limiting component 202, and the limiting component 202 is displaced together with the pipe, thereby reducing the friction between the side wall of the pipe and the fixing device, and increasing the service life of the fixing device.

[0034] Example 2

[0035] Reference Figures 2 to 7, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a cooling water pipe fixing device for a thermal power plant, which solves the problem that the friction between the cooling pipe and the fixing device affects the service life. It includes a telescopic component 102 including a connecting rod 102a fixedly connected to a base 101, a bolt 102b movably connected to one side of the connecting rod 102a, and a telescopic rod 102c slidably connected to the connecting rod 102a, wherein the telescopic rod 102c is slidably connected to the connecting rod 102a to adjust the height of the fixing device, and after adjustment, it is fixed using a bolt 102b.

[0036] Furthermore, the mounting assembly 103 includes a mounting sleeve 103a fixedly connected to the telescopic rod 102c, and a bolt 103b movably connected to the mounting sleeve 103a, wherein the pipeline is installed in the mounting sleeve 103a, and the bolt 103b adjusts the mounting sleeve 103a.

[0037] Furthermore, the support assembly 201 includes a groove 201a provided on the inner wall of the mounting sleeve 103a, a screw 201b rotatably connected in the groove 201a, and a fixed rod 201c movably connected to both sides of the screw 201b, two sets of fixed rods 201c are fixedly connected to the groove 201a, a sliding block 201d slidably connected to the fixed rod 201c, and a contact block 201e fixedly connected to the sliding block 201d, wherein the contact block 201e is in contact with the inner wall of the pipeline, and the sliding block 201d is threadedly connected to the screw 201b. When the pipeline is displaced, the contact block 201e is displaced accordingly, which drives the sliding block 201d to slide on the contact block 201e, and the screw 201b rotates.

[0038] Furthermore, the limiting component 202 includes a slide groove 202a provided on the sliding rod, an extrusion block 202b disposed on the slide groove 202a, the extrusion block 202b is made of elastic material, and a limiting groove 202c provided on the extrusion block 202b, and the limiting groove 202c is "V" shaped.

[0039] Furthermore, the extrusion assembly 203 includes a connecting rod 203a slidably connected to the limiting groove 202c, a moving block 203b fixed to the connecting rod 203a, a spring 203c fixed above the moving block 203b, a fixed block 203d fixed to the spring 203c, and a connecting groove 203e opened on the groove 201a.

[0040] Specifically, when the operator passes the pipeline through the installation sleeve 103a, the bolt 103b on the installation sleeve 103a is in a loose state, and the side wall of the pipeline does not fit with the inner wall of the installation sleeve 103a. After the pipeline is installed, the operator tightens the installation sleeve 103a with the bolt 103b to fix the pipeline on the installation sleeve 103a. At this time, the side wall of the pipeline fits with the inner wall of the installation sleeve 103a. When the cooling water in the pipeline passes through the pipeline, the fluid inertia drives the pipeline to move, and the contact block 201e moves with it. Since the contact block 201e is threadedly connected with the screw rod 201b through the sliding block 201d, the screw rod 201b is driven to rotate when the contact block 201e moves, thereby avoiding the friction between the side wall of the pipeline and the side wall of the installation sleeve 103a due to the inertia of the water flow;

[0041] And when the inertia of the water flow drives the sliding block 201d to move to one side of the groove 201a, in order to prevent the sliding block 201d from hitting the side wall of the groove 201a, when the extrusion block 202b hits the side wall of the groove 201a, due to the extrusion force, the extrusion block 202b is retracted to the inner wall of the groove 201a, so that under the movement of the extrusion block 202b, the limiting groove 202c drives the connecting rod 203a to rise to the end of the limiting groove 202c, and at this time, the connecting rod 203a drives the moving block 203b to rise, and when the flow rate of the water flow decreases, the impact force disappears and the contact block 201e retreats a short distance.

[0042] The remaining structures are the same as those of Example 1.

[0043] Example 3

[0044] Reference Figures 3 to 5 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a cooling water pipe fixing device for a thermal power plant, which solves the problem of friction between the side wall of the pipe and the inner wall of the fixing device. It includes a clamping assembly 204 including a cavity 204a opened above the groove 201a, the cavity 204a is connected to the groove 201a through a connecting groove 203e, a clamping block 204b rotatably connected to one side of the cavity 204a, a clamping block 204c rotatably connected to one side of the clamping block 204b, and a push block 204d slidably connected to one side of the clamping block 204c, and the push block 204d is slidably connected to the installation sleeve 103a.

[0045] Furthermore, the clamping block 204b is fixedly connected with a long rod 204b-1, a clamping hook 204b-2 opened above the long rod 204b-1, and an engaging block 204b-3 fixedly connected between the long rod 204b-1 and the clamping hook 204b-2.

[0046] Furthermore, the block 204c is provided with an engagement groove 204c-1, a clamping groove 204c-2 provided above the engagement groove 204c-1, and a control rod 204c-3 fixedly connected above the clamping groove 204c-2.

[0047] Wherein, due to the position of the connecting groove 203e, when pressure is applied to the bottom of the long rod 204b-1, the clamping block 204b is deflected counterclockwise, the hook 204b-2 on the clamping block 204b is disengaged from the meshing groove 204c-1 on the clamping block 204c, the clamping block 204c is released from the restriction, the meshing block 204b-3 rotates upward, the meshing block 204b-3 presses against the meshing groove 204c-1 so that the clamping block 204c A counterclockwise deflection occurs, causing the control rod 204c-3 to move a short distance into the cavity 204a. When the card block 204c needs to be connected to the card block 204b, the push block 204d is pushed inward, the card block 204c is pressed down, and the engaging groove 204c-1 on the card block 204c engages with the hook 204b-2 on the card block 204b, and the engaging block 204b-3 enters the engaging groove 204c-1.

[0048] Furthermore, the sliding assembly 205 includes a fixing frame 205a fixedly connected to the control rod 204c-3, the fixing frame 205a fixedly connected to the front end of the control rod 204c-3 with a gap between the fixing frame 205a and the side wall of the mounting sleeve 103a, a bracket 205b fixedly connected to the fixing frame 205a, and a roller 205c rotatably connected to the bracket 205b.

[0049] When the pipe passes through the installation sleeve 103a, the pipe fits with the roller 205c to drive the roller 205c to rotate, thereby reducing the friction between the pipe and the side wall of the installation sleeve 103a.

[0050] In summary, after the pipe passes through the inner side of the installation sleeve 103a, the pressure of the water flow drives the pipe to move a certain distance, and the extrusion block 202b hits the side wall of the groove 201a. When the fixing block 203d on the extrusion block 202b passes through the connecting groove 203e and applies pressure to the bottom of the long rod 204b-1, the clamping block 204b deflects counterclockwise, and the hook 204b-2 on the clamping block 204b disengages from the meshing groove 204c-1 on the clamping block 204c. The clamping block 204c is released from the restriction, and the meshing block 204b-3 rotates upward, and the meshing block 204b-3 is engaged. 4b-3 presses against the engaging groove 204c-1 to make the block 204c deflect counterclockwise, so that the control rod 204c-3 moves a short distance into the cavity 204a, so that the sliding assembly 205 on the control rod 204c-3 shrinks a short distance inward, so that the roller 205c and the side wall of the mounting sleeve 103a are at the same level, and the pipeline is tightly installed on the mounting sleeve 103a, and when the pipeline moves in the mounting sleeve 103a, the push block 204d can be pressed inward to reduce the friction between the pipeline and the side wall of the mounting sleeve 103a.

[0051] The remaining structure is the same as that of Example 2.
