[0002] A thermal power plant, also known as a thermal power station, is a facility that uses the heat energy generated by burning fuel to generate electric power. The small-scale circulating water cooling equipment in a thermal power plant usually refers to the relatively small cooling systems used in the power plant. These systems are designed to meet the cooling requirements of specific parts or small units. The circulating water cooling equipment usually consists of a small cooling tower, small water pumps, and a pipeline system.

[0003] During use, the water conveyance pipelines in the pipeline system are usually arranged on the surface of the transformer housing. The flow of water directly absorbs the heat generated by the transformer to achieve effective cooling. However, in the prior art, the transformer adopts a single-pipeline water cooling system, where a single pipeline is arranged on the surface of the transformer housing for cooling. The heat exchange area of a single pipeline is limited, and it may not be able to meet the heat generated by the transformer under high load, resulting in insufficient cooling efficiency. Moreover, the water cooling pipeline adopts an integrated design, which may be difficult to clean and maintain. Scaling may occur on the inner wall of the pipeline during long-term operation, reducing the cooling effect of the circulating water cooling system. Summary of the Utility Model

[0036] Furthermore, the present utility model is described in detail in conjunction with the schematic diagrams. When describing the embodiments of the present utility model in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally not in accordance with the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein.

[0037] Embodiment 1

[0038] Referring to Figures 1-3 , this is the first embodiment of the present utility model, which provides a clamping mechanism. This device includes an installation unit 100, including a connecting member 101 and a straight pipe 102 provided on the connecting member 101; and,

[0039] The clamping unit 200 includes a first connecting cylinder 201 arranged on the straight pipe 102, a first clamping base 202 arranged on the first connecting cylinder 201, a second clamping base 203 movably arranged on the first clamping base 202, and a second connecting cylinder 204 arranged on the second clamping base 203.

[0040] Among them, a positioning block 202a is arranged on the first clamping base 202, a clamping block 202b is arranged at one end of the first clamping base 202 away from the positioning block 202a, and a sliding block 202c is slidably arranged on the first clamping base 202 directly below the clamping block 202b. The sliding block 202c is located between the clamping block 202b and the positioning block 202a.

[0041] Among them, a receiving groove 203a is formed inside the second clamping base 203, two symmetrically arranged self-locking components 203b are arranged on the receiving groove 203a, and a positioning groove 203c is formed at one end of the second clamping base 203 away from the second connecting cylinder 204.

[0042] During the use process, the second clamping base 203 is movably installed on the first clamping base 202. The elbow pipe 206 is movably connected between every two adjacent first connecting cylinders 201. The straight pipe conveys cold water to the elbow pipe 206 along the connecting piece 101, so as to absorb the heat dissipated from the surface of the shell 402 of the transformer 403. When the staff in the power plant finds that the single arrangement of the elbow pipes 206 on the first connecting cylinder 201 is difficult to meet the heat absorption of the transformer 403 under high load, the second clamping base 203 can be installed on the first clamping base 202, and the elbow pipe 206 is movably connected between every two adjacent first connecting cylinders 201, so as to increase the number of elbow pipes 206 arranged on the surface of the transformer 403, increase the water-cooled area for heat absorption of the heat generated by the transformer 403, and improve the effect of absorbing the high heat generated by the transformer 403.

[0043] A space matching the clamping block 202b on the first clamping base 202 is arranged on the second clamping base 203. The self-locking component 203b in the receiving groove 203a can lock between the sliding block 202c and the clamping block 202b, which is convenient for the second clamping base 203 to be installed on the first clamping base 202. The arrangement of the positioning block 202a and the positioning groove 203c can prevent the second clamping base 203 from rotating on the first clamping base 202 and affecting the use process of the second connecting cylinder 204. When the staff needs to disassemble the second clamping base 203, only need to press the second clamping base 203, and the self-locking component 203b will slip off from the first clamping base 202 along the sliding block 202c, so as to realize the disassembly of the second clamping base 203 from the first clamping base 202, thereby improving the convenience of installation and disassembly of the second clamping base 203 on the first clamping base 202.

[0044] Both ends of the first connecting cylinder 201 and the second connecting cylinder 204 are made of a soft and corrosion-resistant material. When one end of the bent pipe 206 is inserted into one end of the first connecting cylinder 201 or the second connecting cylinder 204, the soft material can more easily fit on the surface of the bent pipe 206, thereby increasing the sealing performance of the connection between the bent pipe 206 and one end of the first connecting cylinder 201 or the second connecting cylinder 204. Moreover, the bent pipe 206 and the first connecting cylinder 201 or the second connecting cylinder 204 can be installed and disassembled, which is convenient for the staff in the power plant to disassemble, clean and maintain the bent pipe 206, and prevent the bent pipe 206 from being blocked, thus affecting the water cooling effect of the bent pipe 206.

[0045] Embodiment 2

[0046] Refer to Figure 1 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is: the self-locking assembly 203b includes a guide rod 203b-1 with one end disposed on the receiving groove 203a, a self-locking block 203b-2 slidably disposed on the other end of the guide rod 203b-1, a fixing block 203b-3 disposed on the self-locking block 203b-2, and a spring 203b-4 disposed on the fixing block 203b-3. The spring 203b-4 is disposed on the surface of the guide rod 203b-1, and a slide rail 203b-5 matching the fixing block 203b-3 is disposed on the receiving groove 203a.

[0047] Compared with Embodiment 1, further, bent pipes 206 are respectively disposed at both ends of the second connecting cylinder 204.

[0048] Wherein, an arc-shaped pipe 205 is movably disposed on the first connecting cylinder 201, and the other end of the arc-shaped pipe 205 is movably disposed on the second connecting cylinder 204.

[0049] During use, when the operator installs the second snap base 203 on the first snap base 202, one end of the snap block 202b is arc-shaped, and the self-locking block 203b-2 as a whole is in the shape of a right-angled inverted trapezoid. Such a design enables the self-locking block 203b-2 to slide on the snap block 202b during installation and then enter between the snap block 202b and the slider 202c, thereby movably locking the second snap base 203 on the first snap base 202. The other end of the snap block 202b is concave, and the inclination angle is the same as that of one end of the slider 202c. When the operator needs to disassemble the second snap base 203, by pressing the second snap base 203, the snap block 202b will move along the space in the second snap base 203, and one end of the self-locking block 203b-2 will slide along the surface of the slider 202c. Under the support of the spring 203b-4 and the guide rod 203b-1, the self-locking block 203b-2 disengages from between the snap block 202b and the slider 202c, and the second snap base 203 is disassembled from the first snap base 202, so as to better control the installation and disassembly of the water-cooling pipeline.

[0050] The bent pipeline 206 is installed at one end of every two adjacent first connecting cylinders 201 or every two adjacent second connecting cylinders 204. Every two adjacent first connecting cylinders 201 are arranged vertically and parallelly. When installed at one end of every two adjacent first connecting cylinders 201, one end of the bent pipeline 206 is connected to the lowermost end of the first connecting cylinder 201, and the other end of the bent pipeline 206 is connected to the uppermost end of the first connecting cylinder 201, and so on; every two adjacent second connecting cylinders 204 are arranged vertically and parallelly. When installed at one end of every two adjacent second connecting cylinders 204, one end of the bent pipeline 206 is connected to the uppermost end of the second connecting cylinder 204, and the other end of the bent pipeline 206 is connected to the lowermost end of the second connecting cylinder 204, and so on. Such a connection method facilitates the flow of cold water in the water pipe under the thrust of the water pump 301 and the action of the self-gravity of the water, thereby achieving the water-cooling effect and absorbing the heat generated by the transformer 403.

[0051] The arc-shaped pipe 205 is used to connect the first connecting cylinder 201 and the second connecting cylinder 204 at both ends of the straight pipeline 102. When the second connecting cylinder 204 is added, the operator in the power plant needs to open the lowermost ends of the first connecting cylinder 201 and the second connecting cylinder 204 at both ends and insert the arc-shaped pipe 205, so as to facilitate the transfer of the cold water in the bent pipeline 206 on the first connecting cylinder 201 to the bent pipeline 206 on the second connecting cylinder 204 along the arc-shaped pipe 205, increase the water-cooling area for absorbing the heat generated by the transformer 403, and improve the effect of absorbing the heat dissipated by the transformer 403.

[0052] The remaining structure is the same as that of Embodiment 1.

[0053] Embodiment 3

[0054] Refer to Figure 1, which is the third embodiment of the present utility model. The difference between this embodiment and the second embodiment is that the circulating water cooling device includes:

[0055] A water supply unit 300, including a water pump 301 disposed at one end of the straight pipe 102, a water quality processor 302 disposed on the water pump 301, a water storage tank 303 disposed on the water quality processor 302, and a water inlet pipe 304 disposed on the water storage tank 303;

[0056] A protection unit 400, including a bottom plate 401 disposed on the water quality processor 302, and a housing 402 disposed on the bottom plate 401; and

[0057] An air cooling unit 500, including a fixed base 501 disposed on one side of the water supply unit 300, a strip plate 502 disposed on the fixed base 501, and fan blades 503 disposed on the strip plate 502.

[0058] Compared with Embodiment 2, further, a transformer 403 is disposed on the surface of the bottom plate 401, and a fixing member 403a with one end disposed on the straight pipe 102 is disposed on the transformer 403.

[0059] Wherein, a water outlet pipe 305 with one end disposed on the straight pipe 102 is disposed on the housing 402.

[0060] Preferably, the fixed base 501 is disposed on an air inlet 404, and a protective net 504 is disposed on the air inlet 404.

[0061] Preferably, an air inlet 404 is disposed on the housing 402, and heat dissipation holes 405 are disposed on the housing 402.

[0062] During use, the operator of the power plant introduces water into the water storage tank 303 through the water inlet pipe 304. The water in the water storage tank 303 enters the water quality processor 302. The water quality processor 302 improves the fluidity and refrigeration of the water by treating the water quality and state of the water. The water pump 301 pushes the treated water to flow in the straight pipe 102. Through the connecting member 101, the water in the straight pipe 102 enters the bent pipe 206, thereby forming water cooling on the surfaces of the housing 402 of the transformer 403. Finally, the circulated water is discharged through the water outlet pipe 305.

[0063] The heat dissipation holes 405 increase the air flow volume in the device. The fan blades 503 in the air cooling unit 500 rotate in the same direction, increasing the air flow in the circulating water cooling device, ensuring that the device can maintain an appropriate working temperature even under high load, thereby improving the absorption effect of the water cooling pipe in the circulating water cooling device on the heat generated by the transformer 403 under high load. The protective net 504 is protected outside the fan blades 503 to prevent staff from being injured.

[0064] Between adjacent outer shells 402, the connection between the outer shell 402 and the base is a detachable connection, which is convenient for the power plant staff to maintain the circulating water cooling equipment and increase the water volume of the water cooling pipes in the future, thereby improving the heat absorption effect of the circulating water cooling equipment on the heat generated by the transformer 403.

[0065] The remaining structures are the same as those in Embodiment 2.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. 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.
