Description

Technical Field

[0001] This utility model belongs to the technical field of unit auxiliary equipment, specifically, it relates to a unit technical water supply tank with power and control partition arrangement. Background Technology

[0002] During the operation of hydropower, thermal power and other generating units, the technical water supply system is a key auxiliary system to ensure the safe and stable operation of the units. Its main function is to provide cooling and lubrication water that meets the pressure and flow requirements for the core components of the units, such as bearings, seals and coolers. As the core equipment of the technical water supply system, the unit's technical water supply tank integrates various components such as water pumps, valves, filters, control elements and detection elements, and is responsible for realizing functions such as pressurizing, filtering, regulating and monitoring the operation status of the water supply.

[0003] Existing water supply tank technologies often employ an integrated hybrid layout, where power components (such as pumps, motors, and frequency converters) and control components (such as controllers, relays, signal acquisition modules, and terminals) are integrated into the same cabinet without clear zoning. This layout has the following drawbacks: First, the hybrid layout results in tangled and intertwined pipes and wiring within the cabinet, increasing the difficulty of installation and commissioning, and causing inconvenience for later maintenance and repair. During maintenance of power components, it is easy to accidentally touch control components, leading to equipment failure or even safety hazards. Second, the power and control components have different heat dissipation requirements, making precise heat dissipation control difficult with a hybrid layout. This can easily lead to localized overheating or insufficient heat dissipation, further affecting the overall operational stability of the water supply tank.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Example 1 Please see Figure 1-6 As shown, this embodiment provides a water supply tank with a power and control partition layout, including: a cabinet 1, in which a vertically arranged partition 9 divides the cabinet 1 into an independent power zone 11 and a control zone 12, the partition 9 being a metal shielding partition 9; a water pump 22, a drive motor 23, a frequency converter 14, and power pipelines are installed in the power zone 11, and a shock-absorbing pad 10 is provided at the bottom of the power zone 11, on which the water pump 22 and the drive motor 23 are fixedly mounted; a controller 15, a relay 18, a signal acquisition module 17, and control lines 21 are installed in the control zone 12, and a cooling fan 24 is installed at the top of the control zone 12, and heat dissipation holes 13 are provided on the side wall of the control zone 12; a wiring hole 20 is provided on the partition 9, and a sealing sleeve 19 is installed in the wiring hole 20, through which the control lines 21 pass and are electrically connected to the frequency converter 14 and the drive motor 23 in the power zone 11.

[0020] The cabinet 1, as the core load-bearing component, is internally divided into an independent power zone 11 and a control zone 12 by vertically arranged metal shielding partitions 9. The metal shielding partitions 9 not only serve as physical separators but also possess electromagnetic shielding properties. Made of a metal material with excellent conductivity and shielding performance, the partitions 9 form an effective electromagnetic barrier. This partitioned structure breaks away from the traditional layout of mixing power and control components in water supply tanks, achieving dual physical and electromagnetic isolation between the two types of functional components. The power zone 11 integrates and houses the water pump 22 and drive motor. 23. High-power power components such as frequency converter 14 and power pipelines; water pump 22 provides fluid transport power for the water supply system; drive motor 23 provides power source for the operation of water pump 22; frequency converter 14 is used to adjust the speed of drive motor 23 to achieve precise control of water supply flow; power pipelines are responsible for the transmission of power energy and the transport of fluid medium; at the same time, vibration damping pads 10 are set at the bottom of the power area 11, and water pump 22 and drive motor 23 are directly fixed on vibration damping pads 10. Vibration damping pads 10 are made of oil-resistant and aging-resistant rubber elastic material, which has good vibration damping properties.

The controller 15, as the core instruction unit, is responsible for receiving, processing signals, and outputting control commands. The relays 18 handle circuit switching and signal conversion. The signal acquisition module 17 collects operating parameters of the water pump 22, such as pressure, flow rate, and motor temperature. The control circuit 21 transmits various control signals and commands. To address the heat dissipation issue of the control components, a heat exchanger is installed on the top of the control area 12. The cooling fan 24 has a control area heat dissipation hole 13 on its side wall to form a directional airflow channel and achieve forced air cooling. The partition 9 has a wire hole 20 and a sealing sleeve 19 is installed in the hole. The control line 21 passes through the partition 9 through the sealing sleeve 19 and is electrically connected to the frequency converter 14 and drive motor 23 in the power area 11. The sealing sleeve 19 is made of insulating sealing material, which not only ensures the smooth passage of the control line 21, but also achieves sealing isolation at the wire hole 20, and avoids the risk of wear or short circuit caused by direct contact between the line and the metal partition 9.

[0021] Example 2 Please see Figure 1-6 As shown, in this embodiment, a plurality of power zone heat dissipation holes 26 are provided on the side wall of the power zone 11. A dustproof net 8 is installed at the power zone heat dissipation hole 26. The shock-absorbing pad 10 is a rubber shock-absorbing pad 10. The shock-absorbing pad 10 is provided with mounting holes that match the base of the water pump 22 and the drive motor 23. The water pump 22 and the drive motor 23 are fastened to the shock-absorbing pad 10 by bolts. The water pump 22 is connected to a water pipe 7, and the other end of the water pipe 7 passes through the side wall of the cabinet 1 and is located outside the cabinet 1.

[0022] The shock-absorbing pad 10 is made of rubber. The shock-absorbing pad 10 has mounting holes that match the base of the water pump 22 and the drive motor 23. The water pump 22 and the drive motor 23 are fastened to the shock-absorbing pad 10 with bolts. The shock-absorbing pad 10 is made of oil-resistant and aging-resistant rubber elastic material, which has good vibration absorption and damping energy dissipation characteristics. At the same time, several power zone heat dissipation holes 26 are opened on the side wall of the power zone 11. Dustproof nets 8 are installed at the power zone heat dissipation holes 26 to achieve the dual effect of heat dissipation and dust prevention in the power zone 11. The water pump 22 is connected to a water pipe 7, and the other end of the water pipe 7 passes through the side wall of the cabinet 1 and is located outside the cabinet 1, completing the input and output transmission of fluid medium.

[0023] Temperature sensor 25 is also installed in control area 12. Temperature sensor 25 is electrically connected to controller 15. Controller 15 is electrically connected to cooling fan 24. Power module 16 is also installed in control area 12. Power module 16 is electrically connected to controller 15, cooling fan 24, and touch screen 5 respectively.

[0024] Temperature sensor 25 is electrically connected to controller 15, and controller 15 is electrically connected to cooling fan 24, forming an intelligent heat dissipation control system; power module 16 is electrically connected to controller 15, cooling fan 24 and touch display screen 5 respectively, providing stable power supply to each component of control area 12.

[0025] Example 3 Please see Figure 1-6 As shown, in this embodiment, the front of the cabinet 1 is provided with a power area cabinet door 2 and a control area cabinet door 3 corresponding to the power area 11 and control area 12, respectively. Both the power area cabinet door 2 and the control area cabinet door 3 are provided with an observation window 4 and a handle 6. The control area cabinet door 3 is also equipped with a touch screen display 5, which is electrically connected to the controller 15.

[0026] The cabinet 1 features independent doors facing the power area 11 and control area 12, completely isolating the operation of the two functional areas. Operators can open the corresponding doors individually for maintenance as needed, avoiding the exposure of components in another area when opening one door, further reducing the risk of high-voltage electric shock and accidental contact with components. The observation window 4 on the cabinet door allows operators to directly observe the operating status of the components inside the cabinet without opening the door, improving the convenience of inspection. The handle 6 facilitates the opening and closing of the cabinet door, improving operational convenience. The newly added touch screen 5 on the control area cabinet door 3 is electrically connected to the controller 15, realizing visualized monitoring and intelligent operation of the equipment's operating status. Operators can view operating parameters such as water pump 22 pressure, flow rate, motor temperature, and cabinet temperature in real time through the touch screen, and can also directly issue commands such as speed adjustment and start / stop control through the touch screen. Compared with traditional button control or external monitoring equipment, the operation is more intuitive and convenient, while reducing the connection of external lines and reducing potential failure points.

[0027] Working principle: Cabinet 1 is vertically divided into an independent power zone 11 and a control zone 12 by a metal shielding partition 9, forming a dual physical and electromagnetic isolation.

The front of cabinet 1 has independent cabinet doors corresponding to the two zones, each equipped with an observation window 4 and a handle 6. The control zone cabinet door 3 is additionally equipped with a touch screen display 5. During use, the metal shielding partition 9 blocks electromagnetic interference, and the shock-absorbing pad 10 absorbs vibration and reduces noise; the power zone 11 realizes fluid transportation and precise flow regulation, and takes into account both heat dissipation and dust prevention; the control zone 12 forms an intelligent heat dissipation system through the temperature sensor 25, the controller 15, and the cooling fan 24; the signal acquisition module 17 captures operating parameters in real time; the controller 15 transmits instructions through a sealed line; and the touch screen 5 realizes parameter visualization and instruction issuance.
