Description

Technical Field

[0001] The present application relates to the technical field of flow regulating devices, and specifically discloses a circulating water regulating device for a water source air-conditioning reservoir. Background Art

[0002] When used in large-scale water source air-conditioning systems, a large amount of ice water is required for continuous cooling. Most of the time, a large amount of water and ethylene glycol mixture is stored in a water reservoir, and several U-shaped copper tubes are installed in the water reservoir. During idle time, the supercooled water and ethylene glycol mixture obtained by heat exchange in the plate heat exchanger is introduced into the water reservoir to reduce the temperature of the mixed liquid in the water reservoir and freeze on the outside of the U-shaped copper tube.

[0003] During the continuous ice-making process, since there is an uninterrupted supply of cold water into the water reservoir, the water in the water reservoir will also be discharged to the heat exchange unit through the outlet and then passed into the plate heat exchanger for circulation, that is, the cold water passed into the water reservoir is circulating water. Usually, large-scale water-source air-conditioning systems are used in large shopping malls or large indoor closed environments. The idle time period is at night. During the ice-making process, the volume of the mixed liquid in the water reservoir will increase. At the same time, the increased non-fluid ice will also block the flow of the mixed liquid, which will easily cause the water level in the water reservoir to rise and overflow. Therefore, it is usually necessary to arrange night patrol personnel to observe the water level in the water reservoir. When the water level in the water reservoir is observed to rise, the valves of the water inlet and outlet ports of the water reservoir need to be controlled to reduce the water inlet flow and increase the water inlet flow. In the prior art, there is no circulating water inlet structure that can automatically change the flow rate according to the liquid level height in the water reservoir.

[0004] Therefore, in view of this, the inventor provides a water source air conditioning water tank circulating water regulating device to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem in the traditional water source air conditioning system that there is no circulating water inlet structure which can automatically change the flow rate according to the liquid level height in the water reservoir.

[0006] In order to achieve the above-mentioned object, the basic scheme of the present utility model provides a circulating water regulating device for a water source air conditioning water reservoir, comprising a detection box with a through groove at the bottom, a water inlet pipe transversely fixed to one side of the detection box, a water inlet structure provided in the water inlet pipe, and a liquid level detection structure provided in the detection box;

[0007] The liquid level detection structure includes a rotating shaft rotatably connected to the detection box and an air bag fixed to the rotating shaft and filled with gas;

[0008] One end of the rotating shaft extends into the water inlet pipe and is coaxially arranged with the water inlet pipe, and a water outlet groove is opened on one side of the bottom of the water inlet pipe;

[0009] The water inlet structure includes a sealing plate fixed to the free end of the water inlet pipe, a water guide plate coaxially fixed to the rotating shaft and flush with the height of the air bag, and a water stop platform fixed to the inner wall of the water inlet pipe on the inner side of the water outlet groove and fits the outer wall of the rotating shaft. When the water guide plate and the water stop platform are in contact with each other, they are inclined toward the water outlet groove. A water inlet groove is opened on the top of the water inlet pipe, which can be connected to the water outlet groove.

[0010] Furthermore, connecting rods are fixedly connected to both ends of the rotating shaft in the detection box, and the air bag is fixedly connected between the connecting rods at both ends.

[0011] Furthermore, a baffle that can resist the water guide plate is fixedly connected to the inner side of the top of the water outlet.

[0012] Furthermore, one side of the water inlet pipe is fixedly connected to and communicated with a water discharge structure, and when the water level in the water reservoir is higher than a predetermined height, the water is discharged through the water discharge structure.

[0013] Furthermore, the drainage structure includes a drainage pipe fixedly connected to one side of the water inlet pipe and a drainage groove opened on the water stop platform and connected to the drainage pipe.

[0014] Furthermore, the top height of the drainage channel is higher than the top height of the drainage pipe.

[0015] The principle and effect of this solution are:

[0016] 1. Compared with the prior art, the present invention mounts the detection box and the water inlet pipe at a certain height on the side wall of the water reservoir, which can also be a safe height. Circulating water is introduced through the water inlet slot at the top of the water inlet pipe. When the water in the water reservoir does not reach the safe height, the water guide plate is impacted by the circulating water and fits against the water stop, exposing the water outlet slot to allow the circulating water to be discharged into the water reservoir.

[0017] 2. Compared with the prior art, in the process of the liquid level in the water reservoir rising and rising to above the safe height, the mixed liquid in the water reservoir first contacts the air bag, and the buoyancy of the air bag lifts the water guide plate to overcome the impact force of the circulating water introduced from the water inlet trough, so that the water guide plate rises with the liquid level until it rises above the water outlet trough, and cooperates with the water stop platform to achieve the blocking of the water inlet trough, so that the circulating water no longer enters the water reservoir, preventing the water in the water reservoir from overflowing.

[0018] 3. Compared with the prior art, the present invention can not only stop the supply of circulating water when the mixed liquid overflows from the water reservoir, but also, during normal use, the height of the air bag and the water guide plate can be kept at the normal liquid level in the water reservoir. When the water inlet pipe is placed, the normal liquid level can be aligned with the middle section of the outlet trough. In this way, when there is a lack of water in the water reservoir, the height of the air bag and the water guide plate can be lowered to increase the size of the outlet trough and the amount of circulating water supplied. This solves the problem in traditional water source air conditioning systems that there is no circulating water inlet structure that can automatically change the flow rate according to the liquid level in the water reservoir.

[0025] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0026] The figure marks in the drawings of the specification include: water inlet main pipe 1, water reservoir 2, water outlet branch pipe 3, copper pipe 4, drain pipe 5, detection box 6, water inlet pipe 7, rotating shaft 8, water guide plate 9, water stop platform 10, light baffle 11, air bag 12, connecting rod 13, water outlet groove 14.

[0027] A circulating water regulating device for a water source air conditioning reservoir, for example Figure 1 and Figure 2 As shown:

[0028] In this embodiment, a total of six groups of water reservoirs 2 are built, and the water reservoirs 2 are all supplied with mixed liquid through a water inlet main pipe 1. The water reservoirs 2 are in parallel and not connected to each other. The water storage main pipes are symmetrically arranged on both sides of the water inlet main pipe 1 to form two groups on the left and right, and the water outlet flow is controlled by a water outlet valve respectively, and the water outlet valves on the same side are all connected to a water outlet branch pipe 3.

[0029] Each water reservoir 2 is equipped with an independent circulating water regulating device, and each is connected to the water inlet main 1. In the water reservoir 2, a plurality of U-shaped copper pipes 4 arranged in sequence are also set up to make ice.

[0030] Specifically, such as Figure 3 、 Figure 4 and Figure 5 As shown, the circulating water regulating device includes a detection box 6, a water inlet pipe 7 welded to the left side of the detection box 6, a water inlet structure installed in the water inlet pipe 7 and a liquid level detection structure installed in the detection box 6.

[0031] A through slot is formed at the bottom of the detection box 6. The liquid level detection structure comprises a rotating shaft 8 rotatably mounted between the inner walls of the detection box 6, connecting rods 13 fixedly mounted at each end of the rotating shaft 8, and an air bag 12 fixedly mounted between the connecting rods 13. The air bag 12 is filled with gas, which in this embodiment is helium.

[0032] The left side of the detection box 6 is provided with an axial hole for the rotating shaft 8 to pass through, and the rotating shaft 8 that passes through the axial hole and enters the water inlet pipe 7 is coaxial with the water inlet pipe 7. The bottom left side of the water inlet pipe 7 is provided with a water outlet slot 14.

[0033] The water inlet structure includes a sealing plate fixedly mounted at the left end of the water inlet pipe 7, a water guide plate 9 coaxially fixed to the rotating shaft 8 within the water inlet pipe 7, and a water stop 10 installed within the water inlet pipe 7. The height of the water guide plate 9 is aligned with that of the air bag 12, and the surface area of ​​the air bag 12 that contacts the liquid surface in the water reservoir 2 is much larger than that of the water guide plate 9. This ensures that when the air bag 12 contacts the liquid surface, it imparts sufficient force to the water guide plate 9 to overcome the impact of the circulating water. When the water guide plate 9 contacts the water stop 10, it tilts at a certain angle toward the liquid outlet.

[0034] In this embodiment, the two side end surfaces of the water guide plate 9 are respectively in contact with the wall surface on the same side. The free end surface of the water stop platform 10 is also in contact with the outer wall of the rotating shaft 8, and the two side end surfaces of the water stop platform 10 are also in contact with the wall surface on the same side.

[0035] In addition, a baffle is fixedly installed on the inner side of the top of the water outlet trough 14, and a water inlet trough that can be connected to the water outlet trough 14 is opened in the water inlet pipe 7. When the water guide plate 9 is lifted to the top of the water outlet trough 14, it will resist the baffle, and the water outlet trough 14 will be isolated by the water guide plate 9 and the water stop platform 10.

[0036] Furthermore, a drainage structure is fixedly installed on the inner side of the water inlet pipe 7. The drainage structure includes a drainage pipe 5 fixedly installed on the inner side of the water inlet pipe 7 and a drainage groove opened on the water stop platform 10 and connected to the drainage pipe 5. A through hole for the drainage pipe 5 to pass through is opened on the detection box 6. In this embodiment, the water storage tanks on the same side can share a drainage pipe 5. The drainage groove runs from the left end face of the water stop platform 10 to the top of the drainage pipe 5. The drainage groove is a curved groove. The top height of the drainage groove is higher than the height of the top of the drainage pipe 5 and the baffle. It is used to prevent the mixed liquid discharged from other water storage tanks from flowing into the water storage tank. It can also prevent the mixed liquid from being discharged from the drainage groove when the circulating water is normally supplied.

[0037] When the utility model is used, the detection box 6 and the water inlet pipe 7 are placed in the water reservoir 2, and the outlet of the water inlet pipe 7 is at the liquid level under normal conditions, and the liquid level is submerged to the middle of the outlet.

[0038] At this time, the air bag 12 will be lifted up by the liquid level, and the water guide plate 9 will be lifted up simultaneously, controlling the flow rate of the circulating water introduced by the water inlet slot to be normal flow rate;

[0039] As the liquid level in reservoir 2 rises and reaches a safe height, the mixed liquid in reservoir 2 lifts airbag 12, and the buoyancy of airbag 12 lifts water guide plate 9, overcoming the impact of the circulating water entering from the water inlet slot. This causes water guide plate 9 to rise with the liquid level until it reaches above water outlet slot 14. This, in conjunction with water stop 10, seals the water inlet slot, preventing circulating water from entering reservoir 2. Simultaneously, overflowing mixed liquid is discharged through drain pipe 5 via the drain channel into drain pipe 5, preventing water in reservoir 2 from overflowing into the outside environment.

[0040] When the water reservoir 2 is short of water, the height of the air bag 12 is lowered due to the influence of the liquid level, thereby driving the height of the water guide plate 9 to lower, so as to increase the size of the water outlet 14 and increase the circulating water supply.

[0041] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
