However, after prolonged use, existing cooling water tanks easily accumulate dirt and impurities inside, severely impacting cooling efficiency and equipment lifespan. Furthermore, the limitations of traditional cooling water tank design make cleaning extremely inconvenient. Most cooling water tanks have complex internal structures, requiring the water to be drained before manual cleaning, which is not only labor-intensive and time-consuming but also difficult to thoroughly remove dirt from hard-to-reach areas. While some cooling water tanks have removable components to aid cleaning, the disassembly process is cumbersome, and repeated disassembly can compromise sealing performance, leading to leaks. Simultaneously, existing cooling water tanks lack effective observation and temperature monitoring methods, making it impossible to monitor the internal condition and water temperature changes in real time, hindering timely detection and intervention of abnormalities, and reducing the efficiency and safety of cooling water tank use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] In this technical solution, a cooling water tank that is easy to clean includes a cooling water tank body 1. A cleaning base plate 4 is installed inside the cooling water tank body 1, and a tank top cover 3 is hinged to the top of the cooling water tank body 1. A circulating water pump 11 is installed at the center of the bottom inside the cooling water tank body 1, and an electric push rod 24 is installed at the top of the circulating water pump 11. The cleaning base plate 4 is connected to the drive end of the electric push rod 24. A sealing ring 15 is fitted on the outside of the cleaning base plate 4, and the sealing ring 15 is tightly fitted to the inner wall of the cooling water tank body 1. A water outlet pipe 12 is installed at the outlet end of the circulating water pump 11, and a water inlet pipe 13 is installed at the inlet end of the circulating water pump 11. A water outlet 14 is opened on the left side of the top of the cleaning base plate 4, and a water inlet 16 is opened on the right side of the top of the cleaning base plate 4. The water outlet pipe 12 is connected to the water outlet 14, and the water inlet pipe 13 is connected to the water inlet 16.

[0024] The cleaning base plate 4 and electric push rod 24 enable quick and convenient cleaning of the interior of the cooling water tank body 1; the circulating water pump 11, water outlet pipe 12, water inlet pipe 13, water outlet 14 and water inlet 16 form a water circulation system to ensure cooling effect; the sealing ring 15 ensures the sealing between the cleaning base plate 4 and the cooling water tank body 1 to prevent cooling water leakage; the hinged design of the tank top cover 3 makes it easy to open and close, and facilitates maintenance and observation of the internal condition;

[0025] When the cooling water tank needs to be cleaned, the electric push rod 24 is activated, which drives the cleaning base plate 4 to rise, bringing the dirt and other impurities attached to the cleaning base plate 4 and the bottom of the cooling water tank body 1 to the water surface for easy cleaning; when the circulating water pump 11 is working, the water in the cooling water tank is drawn out from the inlet 16 through the inlet pipe 13, transported to the external cooling equipment for heat exchange, and then flows back into the cooling water tank body 1 from the outlet 14 through the outlet pipe 12, forming a cooling water circulation;

[0026] The dimensions of the cooling water tank body 1 are designed according to actual usage requirements. For example, the length × width × height can be 1000mm × 600mm × 800mm. The thickness of the cleaning base plate 4 is 10-15mm, and its size is slightly smaller than the internal cross-section of the cooling water tank body 1. The distance between the cleaning base plate 4 and the inner wall of the cooling water tank body 1 is 3-5mm. The stroke of the electric push rod 24 is determined according to the height of the cooling water tank body 1, which is generally 600-700mm, and the thrust is 500-1000N. The flow rate of the circulating water pump 11 is 5-15m³ / h, and the head is 5-10m. The diameter of the outlet pipe 12 and the inlet pipe 13 is 30-60mm, and the wall thickness is 2-4mm.

[0027] Multiple raised scraping strips are installed on the cleaning base plate 4 to enhance the cleaning effect on the bottom of the cooling water tank body 1; a universal joint is installed at the connection between the electric push rod 24 and the cleaning base plate 4 to avoid uneven force on the electric push rod 24 due to installation errors; one-way valves are installed at the inlet and outlet of the circulating water pump 11 to prevent water backflow.

[0028] In some technical solutions, the outer wall of the sealing ring 15 is provided with a cleaning slope 19, which is fitted to the inner wall of the cooling water tank body 1.

[0029] During the cleaning process of lifting the base plate 4, the cleaning slope 19 can effectively scrape off the dirt and impurities attached to the inner wall of the cooling water tank body 1, while ensuring that the sealing ring 15 is tightly fitted to the inner wall of the cooling water tank body 1, maintaining good sealing performance, and improving the cleanliness and reliability of the cooling water tank.

[0030] As the cleaning base plate 4 rises or falls under the action of the electric push rod 24, the cleaning inclined surface 19 on the outer wall of the sealing ring 15 slides relative to the inner wall of the cooling water tank body 1, pushing the dirt towards the bottom or top of the cooling water tank to achieve automatic cleaning; at the same time, the fitting design of the cleaning inclined surface 19 ensures that the sealing ring 15 remains sealed during the movement.

[0031] The angle between the cleaning bevel 19 and the outer wall of the sealing ring 15 is 50°-55° to balance the scraping ability and sealing effect; the radial width of the sealing ring 15 is 15-20mm, of which the width of the cleaning bevel 19 accounts for 60%-70% of the width of the sealing ring 15; the surface roughness of the cleaning bevel 19 is controlled at Ra0.6-Ra1.2μm to reduce the possibility of dirt adhesion;

[0032] Wear-resistant ceramic particles are embedded in the surface of the cleaning slope 19 to further enhance the scraping ability and wear resistance; a dovetail groove structure is set on the contact surface between the sealing ring 15 and the cleaning base plate 4 to enhance the stability of the connection between the two; a water spray nozzle is set on the top of the cleaning slope 19 to spray water to assist in rinsing dirt during the cleaning process.

[0033] In some technical solutions, the sealing ring 15 has a filling cavity 21 inside, and the filling cavity 21 is equipped with an arc-shaped elastic plate 20.

[0034] By utilizing the elastic deformation characteristics of the arc-shaped elastic plate 20, the sealing ring 15 can adapt to the slight shape error of the inner wall of the cooling water tank body 1 or the displacement of the cleaning base plate 4 during the lifting and lowering process, ensuring that the sealing ring 15 is always tightly fitted to the inner wall of the cooling water tank body 1, thereby improving the sealing performance; at the same time, the arc-shaped elastic plate 20 can buffer the impact force when the cleaning base plate 4 is lifted and lowered, reducing wear.

[0035] When the cleaning base plate 4 is subjected to force or the water pressure in the cooling water tank changes, causing the sealing ring 15 to be squeezed, the arc-shaped elastic plate 20 undergoes elastic deformation in the filling cavity 21, pushing the outer wall of the sealing ring 15 to tightly fit the inner wall of the cooling water tank body 1; during the lifting and lowering process of the cleaning base plate 4, the arc-shaped elastic plate 20 absorbs vibration and impact energy, protecting the sealing ring 15 and the inner wall of the cooling water tank body 1.

[0036] The cross-sectional shape of the filling cavity 21 is semi-circular with a diameter of 6-8mm; the arc-shaped elastic plate 20 is made of 65Mn spring steel with a thickness of 0.6-0.8mm, and the curvature is customized according to the inner diameter of the sealing ring 15 and the curvature of the inner wall of the cooling water tank body 1 to ensure a pre-tightness of 0.5-1mm with the inner wall of the cooling water tank body 1 in the initial state; the filling cavities 21 are evenly distributed along the circumference inside the sealing ring 15, and there are 6-8 of them;

[0037] Memory foam is filled into the filling cavity 21 to further enhance the sealing and cushioning effect; limiting protrusions are set at both ends of the arc-shaped elastic plate 20 to prevent excessive displacement within the filling cavity 21; a pressure sensing diaphragm is set on the outside of the sealing ring 15 to monitor the sealing pressure in real time and issue an early warning when the pressure is lower than the threshold.

[0038] In some technical solutions, the top of the tank cover 3 is fitted with an observation glass 6, the inner walls on both sides of the tank cover 3 are equipped with lights 7, a locking block 8 is installed at the center of the upper end of the front side wall of the tank cover 3, and a slot 5 is opened at the center of the upper end of the front side wall of the cooling water tank body 1. The locking block 8 and the slot 5 cooperate with each other.

[0039] The observation glass 6 and the illumination lamp 7 allow operators to observe the water level, water quality, and equipment operation inside the cooling water tank in real time; the cooperation between the locking block 8 and the locking slot 5 enables the quick installation and removal of the tank top cover 3, while ensuring the sealing of the cooling water tank, facilitating maintenance and operation.

[0040] Turn on the spotlight 7 to illuminate the inside of the cooling water tank, and the operator can observe through the observation glass 6; when installing the tank top cover 3, align the locking block 8 with the locking slot 5 and insert it, using the shape of the locking block 8 and the locking slot 5 to fix the tank top cover 3; when disassembling, apply external force to make the locking block 8 disengage from the locking slot 5;

[0042] A nano self-cleaning coating is applied to the surface of the observation glass 6 to reduce the adhesion of dust and water stains; the illumination lamp 7 is equipped with an automatic sensor switch that automatically turns on when the top cover 3 of the slot is opened and automatically turns off when it is closed; a rubber sealing ring is set at the mating point between the card block 8 and the card slot 5 to further improve the sealing and waterproof performance.

[0043] In some technical solutions, a snap-fit ​​groove 9 is provided at the center of the front end of the rear side wall of the top cover 3.

[0044] The slot 9 provides the operator with a point of leverage to open the top cover 3 of the slot, making it easy and convenient to open the top cover 3 of the slot without the need for additional tools, thus improving the ease of operation;

[0045] The operator hooks their fingers into the buckle groove 9 and applies an upward pulling force to overcome the connection force between the top cover 3 and the main body 1 of the cooling water tank, thereby opening the top cover 3.

[0046] The groove 9 has a depth of 20-25mm, a width of 25-30mm, and a semi-elliptical shape; the groove 9 is 12-15mm away from the rear side wall edge of the top cover 3 to ensure uniform force when opening;

[0047] An anti-slip texture is provided inside the buckle groove 9 to increase the friction between the fingers and the buckle groove 9; a flexible rubber protective sleeve is provided on the edge of the buckle groove 9 to prevent fingers from being scratched; a pressure sensor is installed at the bottom of the buckle groove 9 to trigger an alarm when abnormal pulling force is applied to prevent damage to the equipment by force.

[0048] In some technical solutions, a cooling chamber 18 is provided at the upper part of the cooling water tank body 1, and a temperature sensor 17 is installed inside the cooling chamber 18.

[0049] The temperature sensor 17 monitors the water temperature in the cooling chamber 18 in real time, providing accurate temperature data for the operation of the cooling system. This facilitates timely adjustment of the cooling strategy, ensures the cooling effect, and prevents abnormal water temperature from affecting the normal operation of the equipment.

[0050] Temperature sensor 17 converts the real-time monitored temperature signal into an electrical signal and transmits it to the control system via a signal line. The control system compares the received temperature data with a preset temperature range. When the temperature exceeds the range, the control system issues a command to adjust the flow rate of the circulating water pump 11, turn on or off the cooling / heating device, etc., to achieve automatic water temperature regulation.

[0051] Temperature sensor 17 is a PT100 platinum resistance temperature sensor with a measurement range of -40℃ to 150℃ and a measurement accuracy of ±0.3℃; the volume of cooling chamber 18 accounts for 1 / 4 to 1 / 3 of the total volume of cooling water tank body 1; temperature sensor 17 is installed in the center of cooling chamber 18, 50-80mm away from the top of cooling chamber 18.

[0052] Multiple temperature sensors 17 are installed inside the cooling chamber 18 to form a temperature monitoring network, improving the accuracy and comprehensiveness of temperature measurement; signal amplification and filtering circuits are provided for the temperature sensors 17 to enhance signal stability; a temperature display module is installed outside the cooling chamber 18 to display water temperature data in real time for easy on-site viewing.

[0053] In some technical solutions, the bottom of the cooling water tank body 1 is equipped with a supporting base plate 2.

[0054] The supporting base plate 2 is used to support the weight of the cooling water tank body 1, internal equipment, and cooling water, thereby enhancing the stability of the cooling water tank and preventing it from tilting or shaking. At the same time, the supporting base plate 2 can protect the placement surface and prevent damage to the placement surface due to the concentrated weight of the cooling water tank.

[0055] The supporting base plate 2, through close contact with the placement surface, evenly distributes the weight of the cooling water tank onto the placement surface, and uses its own strength and rigidity to withstand pressure, ensuring the stable placement of the cooling water tank;

[0056] The supporting base plate 2 is made of Q235B steel plate with a thickness of 12-18mm; the size of the supporting base plate 2 is 50-80mm larger on each side than the bottom size of the cooling water tank body 1; M12-M16 anchor bolt mounting holes are provided at the four corners of the supporting base plate 2 for fixing the cooling water tank.

[0057] Rubber shock-absorbing pads are attached to the bottom of the supporting base plate 2 to reduce vibration and noise during the operation of the cooling water tank; drainage holes and drainage channels are provided on the supporting base plate 2 to drain water leaking from the cooling water tank in a timely manner; lifting holes are provided on the side of the supporting base plate 2 to facilitate the handling and installation of the cooling water tank.

[0058] Working principle of cooling water tank

[0059] I. Water Cycle Principle

[0060] The circulating water pump 11 is the power core of the entire water circulation system. When the circulating water pump 11 starts, under its suction, water in the cooling water tank flows in from the inlet 16 on the right side of the top of the cleaning base plate 4, and is drawn out of the cooling water tank body 1 through the inlet pipe 13. This water flows to externally connected cooling equipment (such as cooling towers, refrigeration units, etc.), where heat exchange is completed, dissipating the heat it carries or regulating the temperature to lower the water temperature to a suitable range. After cooling, the water flows back to the cooling water tank through the outlet pipe 12 and enters the cooling water tank body 1 from the outlet 14 on the left side of the top of the cleaning base plate 4, thus forming a complete cooling water circulation loop, continuously cooling the external equipment.

[0061] II. Cleaning Working Principle

[0062] When the cooling water tank needs cleaning, the electric push rod 24 plays a crucial role. The operator activates the electric push rod 24 via a command from the control system. The drive end of the electric push rod 24 extends upward, causing the cleaning base plate 4 connected to it to rise synchronously. During the ascent of the cleaning base plate 4, the sealing ring 15 fitted on the outside of the cleaning base plate 4 also moves. The cleaning inclined surface 19 on the outer wall of the sealing ring 15 fits tightly against the inner wall of the cooling water tank body 1, creating relative sliding. The cleaning inclined surface 19, using its specific angle, gradually scrapes off the dirt and impurities adhering to the inner wall of the cooling water tank body 1, causing them to accumulate at the bottom or top of the cooling water tank. Simultaneously, the rising of the cleaning base plate 4 carries the dirt and impurities deposited at the bottom to the surface, facilitating centralized cleaning by the operator. After cleaning, the electric push rod 24 drives the cleaning base plate 4 to descend and reset, and the sealing ring 15 restores the seal between the cleaning base plate 4 and the cooling water tank body 1, ensuring no cooling water leakage.

[0063] III. Sealing Working Principle

[0064] The sealing ring 15 achieves efficient sealing through a multi-layered structural design. On one hand, the sealing ring 15 fits tightly against the inner wall of the cooling water tank body 1, directly blocking the leakage of cooling water from the gap between the cleaning base plate 4 and the cooling water tank body 1. On the other hand, the filling cavity 21 and the arc-shaped elastic plate 20 inside the sealing ring 15 provide adaptive sealing. When the water pressure in the cooling water tank changes or the cleaning base plate 4 experiences slight displacement during lifting, the arc-shaped elastic plate 20 undergoes elastic deformation within the filling cavity 21. This deformation generates an outward thrust, pushing the outer wall of the sealing ring 15 to fit more tightly against the inner wall of the cooling water tank body 1, automatically compensating for changes in the sealing gap caused by external factors, thus maintaining excellent sealing performance and ensuring the normal operation of the cooling water tank.

[0065] IV. Principles of Observation and Monitoring

[0066] Observation Principle: The observation glass 6 embedded in the top of the tank cover 3, together with the illumination lights 7 on both inner walls, allows for observation of the interior of the cooling water tank. When observation of the interior is needed, the operator turns on the illumination lights 7. The light emitted by the lights 7 evenly illuminates the interior space of the cooling water tank, making the water level, water quality, and operating status of the internal equipment clearly visible. The operator can obtain this information directly through the observation glass 6 without opening the tank cover 3, reducing unnecessary operations and the impact on the sealing of the cooling water tank.

[0067] Monitoring Principle: A temperature sensor 17, installed in the cooling chamber 18 at the upper end of the cooling water tank body 1, is responsible for real-time monitoring of the water temperature. The temperature sensor 17 converts the sensed water temperature information into an electrical signal, which is transmitted to the control system via a signal line. The control system has a preset appropriate water temperature range. When the received temperature signal indicates that the water temperature exceeds the preset range, the control system will immediately issue a command to automatically adjust the flow rate of the circulating water pump 11. For example, it may increase the flow rate to speed up the water circulation and enhance the cooling effect, or control the start and stop of the refrigeration / heating device to restore the water temperature to the normal range, thereby achieving precise control of the cooling process and ensuring the stable operation of the cooling system.

[0068] V. Opening and closing principle of the top cover of the trough

[0069] The top cover 3 is connected to the main body 1 of the cooling water tank via a hinge, allowing rotation around the hinge axis. When closing the top cover 3, align the locking block 8 at the center of the upper end of the front side wall of the top cover 3 with the locking groove 5 at the center of the upper end of the front side wall of the main body 1. Then, press down on the top cover 3 to fully insert the locking block 8 into the locking groove 5. The shape and size fit between the locking block 8 and the locking groove 5 ensure a secure fixation of the top cover 3, guaranteeing the airtightness of the cooling water tank. When it is necessary to open the top cover 3, the operator hooks their finger into the retaining groove 9 at the center of the front end of the rear side wall of the top cover 3, applying an upward pulling force to overcome the friction between the locking block 8 and the locking groove 5, as well as the resistance at the seal. This causes the locking block 8 to disengage from the locking groove 5, and simultaneously, the top cover 3 rotates upward around the hinge axis to open, facilitating maintenance and cleaning of the cooling water tank.
