Description

Technical Field

[0001] This utility model relates to the field of cooling water balance technology, and in particular to a cooling water balance device for a refrigeration plant. Background Technology

[0002] The cooling water system plays a crucial role in the operation of a refrigeration plant. As a core facility that provides refrigeration, the refrigeration plant is widely used in many fields such as industrial production, commercial buildings, and data centers. Its stable operation is of irreplaceable significance for ensuring production processes, maintaining indoor environmental comfort, and ensuring secure data storage.

[0003] Cooling water plays a crucial role in heat exchange within a chiller plant system. It circulates within the chiller plant, absorbing the heat generated during equipment operation and carrying it out to maintain the equipment within a suitable temperature range. However, during the cooling water circulation process, due to factors such as evaporation and leakage, cooling water loss is inevitable. To maintain the normal operation of the chiller plant's cooling water system, manual periodic checks of the water tank level and judgment of water replenishment based on experience are commonly used. This method has drawbacks. Manual checks cannot accurately monitor changes in the water tank level in real time, making it difficult to detect cooling water loss in a timely manner. This can easily lead to water tank levels that are too low, affecting the cooling effect of the chiller plant. At the same time, it is difficult to accurately control the amount of water replenishment, which can easily result in excessive or insufficient replenishment. Excessive replenishment will waste water resources and increase the company's operating costs, while insufficient replenishment will fail to meet the cooling needs of the chiller plant and affect its normal operation.

[0004] Therefore, developing a device that can automatically and accurately adjust the cooling water replenishment to achieve cooling water balance has become an urgent technical problem to be solved in the field of refrigeration plants. The present application provides a cooling water balance device for refrigeration plants, which aims to improve the automation level and operational stability of the cooling water system of refrigeration plants and ensure the efficient operation of refrigeration plants. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cooling water balancing device for a refrigeration plant.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cooling water balancing device for a refrigeration plant includes a ground layer, a water tank poured on top of the ground layer, a conveying assembly installed on one inner wall of the water tank, a fixed plate fixed on top of the water tank, a water supply pipe embedded in a through hole on the surface of the fixed plate, a discharge plate welded to one end of the water supply pipe, connecting plates fixed on the inner walls of both sides of the water tank, rods movably connected to through holes on the surface of the connecting plates, a float fixed at the bottom of the rod, an elastic element installed on the side of the rod, an L-shaped plate fixed at the end of the elastic element, and a rubber pad two adhered to the outer wall of one side of the L-shaped plate.

[0008] As a further embodiment of this utility model: the rod includes a limiting plate one, a lifting rod and a limiting plate two. The lifting rod is movably connected to the inner wall of the through hole opened on the surface of the connecting plate. The limiting plate one is fixed to the bottom of the lifting rod and the float and the limiting plate one are fixedly connected. The limiting plate two is welded to the outer wall of the lifting rod.

[0009] As a further embodiment of this utility model: the elastic element includes a T-shaped rod and a spring. The T-shaped rod is movably connected to the inner wall of the through hole opened on the side of the lifting rod. The spring is sleeved on the outer wall of the T-shaped rod, and the two ends of the spring are respectively fixed to the inner wall of one side of the T-shaped rod and the outer wall of one side of the lifting rod. One end of the T-shaped rod is fixedly connected to the inner wall of one side of the L-shaped plate.

[0010] As a further embodiment of this utility model: a horizontal plate is fixed to the inner wall of one side of the pool, and the conveying component is fixedly connected to the horizontal plate. The conveying component includes pipe one, a water pump and pipe two. Pipe two is fixed to the inner wall of the through hole opened on the surface of the horizontal plate, the water pump is fixed to one end of pipe two, and pipe one is fixed to the end of the water pump away from the water pump.

[0011] As a further improvement of this utility model: a splash guard is welded to the top outer wall of the L-shaped plate, and a rubber pad is adhered to one side of the outer wall of the splash guard.

[0012] As a further embodiment of this utility model: a bracket is fixed to the top outer wall of the fixing plate, an electric telescopic rod is fixed to the top outer wall of the bracket, a hanging plate is fixed to the output end of the electric telescopic rod by a pin, and a frame that works in conjunction with the hanging plate is fixed to the top outer wall of the splash-proof frame.

[0013] As a further improvement of this utility model, an overflow hole is provided on the side of the pool.

[0014] As a further improvement of this utility model, a filter screen is fixed at the bottom of the second pipe.

[0015] Compared with the prior art, this utility model provides a cooling water balancing device for a refrigeration plant, which has the following beneficial effects:

[0016] 1. By sensing changes in the cooling water level in the pool through a float ball, the buoyancy drives the lifting rod to move the L-shaped plate. Combined with the elastic force of the elastic element, the rubber pad precisely controls the opening of the outlet plate, realizing automatic and precise replenishment of cooling water. When the cooling water decreases due to evaporation or other reasons, it can be replenished in time. When the liquid level reaches the set height, the replenishment will automatically stop, effectively maintaining the stability of the water volume in the pool and avoiding the impact of too much or too little water on the normal operation of the chiller station.

[0017] 2. A filter screen is installed at the bottom of pipe two in the conveying assembly. During the process of cooling water flowing back from the chiller to the water tank, the filter screen can effectively filter out the particulate matter carried in the cooling water, preventing these impurities from entering the water tank and affecting the quality of the cooling water. The splash guard and rubber pad one reduce the splashing of cooling water during the water replenishment process.

[0018] 3. The electric telescopic rod can intelligently control the water replenishment process according to the operating status of the chiller station. When the chiller station is cooling the cooling water and it has not flowed back to the water tank, the electric telescopic rod drives the hanging plate to move up so that the rubber pad 2 temporarily covers the outlet plate to avoid "accidental water replenishment". When the chiller station has finished cooling and the cooling water flows back, the electric telescopic rod drives the hanging plate to move down and reset, without affecting the normal water replenishment operation. The overflow hole on the side of the water tank can drain excess rainwater in rainy weather to prevent the water level in the tank from being too high.

[0019] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] A cooling water balancing device for a refrigeration plant, such as Figures 1 to 5 As shown, the structure includes a stratum 1, a water tank 2 is poured on top of the stratum 1, a conveying assembly is installed on one inner wall of the water tank 2, a fixing plate 13 is fixed to the top of the water tank 2 by bolts, a water supply pipe 4 is embedded in a through hole on the surface of the fixing plate 13, a discharge plate 14 is welded to one end of the water supply pipe 4, a connecting plate 5 is fixed to the inner walls of both sides of the water tank 2, a rod is slidably connected to a through hole on the surface of the connecting plate 5, a float 8 is fixed to the bottom of the rod, an elastic element is installed on the side of the rod near the top, an L-shaped plate 26 is fixed to the end of the elastic element, and a rubber pad 25 is adhered to the outer wall of one side of the L-shaped plate 26.

[0028] The cooling water can be stored in the water tank 2. The conveying component can transport the cooling water to the refrigeration station to cool the refrigeration station. After the refrigeration station is cooled, the conveying component can put the cooling water back into the water tank 2, so that the cooling water can be recycled. During the cooling process of the refrigeration station, the cooling water will be lost due to evaporation and other reasons. Therefore, when the cooling water returns to the water tank 2 after cooling the refrigeration station, there will be a certain amount of loss. At this time, water needs to be added to the water tank 2.

[0029] Cooling water can be replenished into the water tank 2 by setting up a water supply pipe 4. In order to facilitate the adjustment of the cooling water replenishment amount and avoid over- or under-replenishment, a balancing device needs to be set up to adjust the cooling water replenishment amount.

[0030] In the initial state, when the water tank 2 is empty, the float 8 is at its lowest position relative to the connecting plate 5. When the water supply pipe 4 discharges cooling water through the discharge plate 14, the cooling water enters the water tank 2 and, as the cooling water level rises, the float 8, under the buoyancy of the cooling water, drives the rod and L-shaped plate 26 to move upward along the connecting plate 5. As the L-shaped plate 26 moves upward, the rubber pad 25 on its side gradually blocks the discharge plate 14, causing the flow of cooling water from the water supply pipe 4 to gradually decrease. When the rubber pad 25 completely blocks the opening of the discharge plate 14, the cooling water in the water supply pipe 4 no longer flows into the water tank 2, thus ensuring that the water volume in the water tank 2 tends to be stable.

[0031] When the cooling water in the pool 2 decreases due to evaporation or other reasons, the cooling water level drops, causing the float 8 to drop as well. This causes the L-shaped plate 26 to move downward relative to the outlet plate 14. When a relative opening is created between the L-shaped plate 26 and the outlet plate 14, the cooling water in the water supply pipe 4 re-enters the pool 2 to replenish the water, thereby maintaining the water balance in the pool 2. The elastic element ensures the fit between the rubber pad 25 and the side of the outlet plate 14 by its elasticity, thus ensuring the seal between the L-shaped plate 26 and the outlet plate 14 when the L-shaped plate 26 blocks the opening of the outlet plate 14.

[0032] The rod includes a first limiting plate 9, a lifting rod 16, and a second limiting plate 17. The lifting rod 16 is slidably connected to the inner wall of a through hole on the surface of the connecting plate 5. The first limiting plate 9 is fixed to the bottom of the lifting rod 16 by bolts, and the float 8 is fixedly connected to the first limiting plate 9. The second limiting plate 17 is welded to the outer wall of the lifting rod 16. The elastic element includes a T-shaped rod 18 and a spring 19. The T-shaped rod 18 is slidably connected to the inner wall of a through hole on the side of the lifting rod 16. The spring 19 is sleeved on the outer wall of the T-shaped rod 18, and both ends of the spring 19 are fixed to the inner wall of one side of the T-shaped rod 18 and the outer wall of one side of the lifting rod 16, respectively. One end of the T-shaped rod 18 is fixedly connected to the inner wall of one side of the L-shaped plate 26.

[0033] A float 8 is installed so that the lifting rod 16 can slide along the connecting plate 5 under the buoyancy of the cooling water. The lifting rod 16 guides the movement path of the float 8 and the L-shaped plate 26. The elasticity of the spring 19 ensures the fit between the L-shaped plate 26 and the side of the outlet plate 14. At the same time, it can also ensure that the rubber pad 25 and the outlet plate 14 are always in contact even when the rubber pad 25 wears out after long-term use, thereby improving the sealing effect between the rubber pad 25 and the outlet plate 14. By setting a limit plate 9 and a connecting plate 5, the maximum height of the L-shaped plate 26 can be limited, thereby limiting the highest liquid level in the water tank 2 and preventing the cooling water in the water tank 2 from overflowing due to the unlimited rise of the L-shaped plate 26.

[0034] A horizontal plate 23 is fixed to the inner wall of one side of the water tank 2. The conveying component is fixedly connected to the horizontal plate 23. The conveying component includes a first pipe 20, a water pump 21, and a second pipe 22. The second pipe 22 is embedded and fixed to the inner wall of the through hole opened on the surface of the horizontal plate 23. The water pump 21 is fixed to one end of the second pipe 22 by bolts. The first pipe 20 is fixed to the end of the water pump 21 away from the water pump 21 by bolts. A filter screen 24 is fixed to the bottom of the second pipe 22 by screws.

[0035] The conveying components consist of two sets. One set of conveying components is responsible for conveying cooling water through the water tank 2 to the chiller station (not shown). The other set of conveying components is responsible for conveying cooling water from the chiller station back to the water tank 2. The two sets of pipes 20 can be connected to the inlet and outlet of the chiller station, respectively. The water pump 21 provides power for the conveying of cooling water, and the filter screen 24 can effectively filter the particulate matter contained in the cooling water in the water tank 2.

[0036] The L-shaped plate 26 has a splash guard 12 welded to the top outer wall. A rubber pad 15 is glued to one side of the outer wall of the splash guard 12, and the rubber pad 15 and the rubber pad 25 are flush in the vertical direction.

[0037] The splash guard 12 and rubber pad 15 are provided to reduce splashing when the cooling water in the water supply pipe 4 is discharged from the outlet plate 14.

[0038] The top outer wall of the fixed plate 13 is fixed with a bracket 7 by bolts, the top outer wall of the bracket 7 is fixed with an electric telescopic rod 3 by bolts, the output end of the electric telescopic rod 3 is fixed with a hanging plate 11 by a pin, and the top outer wall of the splash-proof frame 12 is fixed with a frame 10 that works with the hanging plate 11 by screws.

[0039] When the conveying assembly transports the cooling water in the water tank 2 to the refrigeration station for cooling, the electric telescopic rod 3 drives the hanging plate 11 to move upward. During the upward movement of the hanging plate 11, the frame 10 is pulled, which causes the rubber pad 25 to move vertically and temporarily cover the opening of the outlet plate 14. When the cooling water in the water tank 2 is transported to the refrigeration station for cooling and does not flow back to the water tank 2 in time, the water level in the water tank 2 will temporarily drop. The electric telescopic rod 3 limits the L-shaped plate 26 to prevent the cooling water in the water supply pipe 4 from being introduced into the water tank 2 through the outlet plate 14 and causing "accidental water replenishment". After the refrigeration station has finished cooling, the cooling water flows back to the water tank 2. At this time, the electric telescopic rod 3 drives the hanging plate 11 to move downward and reset.

[0040] Because the frame 10 has a square hole structure, it prevents the frame 10 and the hanging plate 11 from jamming together when the rubber pad 25 and the L-shaped plate 26 move up or down under the buoyancy of the cooling water.

[0041] The side of the water tank 2 is provided with an overflow hole 6;

[0042] Since the water tank 2 is set up in the open air, when rainwater falls into the water tank 2 during rainy weather, the liquid level in the water tank 2 will continuously rise. The overflow hole 6 will cause the liquid level in the water tank 2 to reach a certain value and then be discharged from the overflow hole 6, so as to prevent the liquid level in the water tank 2 from being too high due to the influence of rainwater.

[0043] Working principle: During operation, the conveying component transports the cooling water in the water tank 2 to the refrigeration station for cooling and then returns it to the water tank 2. When the cooling water decreases due to evaporation, the liquid level in the water tank 2 drops, and the float 8 moves down accordingly. The L-shaped plate 26 moves down relative to the outlet plate 14, creating an opening. The water supply pipe 4 replenishes water through the outlet plate 14. When the liquid level rises, the float 8 floats up, driving the lifting rod 16 to move the L-shaped plate 26 up. After the L-shaped plate 26 moves up, the rubber pad 25 blocks the opening of the outlet plate 14, reducing the amount of water replenished until the outlet plate 14 is completely blocked, stopping the water supply pipe 4 from replenishing water.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
