Description

Technical Field

[0001] The utility model relates to the technical field of water supply tanks, in particular to a secondary water supply tank. Background Art

[0002] Secondary water supply is stored and pressurized before being supplied to users' homes through water supply pipes. Due to the insufficient water supply pressure of municipal tap water, the water demand of users living in high-rise buildings cannot be guaranteed. Therefore, it is necessary to use secondary water supply with the help of booster water supply equipment to meet the water supply requirements. Due to long-term water storage, a large amount of pollutants are deposited at the bottom of the traditional secondary water supply tank, which is yellow and emits the smell of bleach. If the secondary water supply tank is to be cleaned, the water in the tank must be drained and workers can enter the tank to clean it. First, it is not timely, second, it increases operating costs, and third, there are safety risks. If the secondary water supply equipment is not cleaned for a long time or cannot be cleaned in time, it is easy to breed bacteria, causing secondary pollution of water quality and endangering human health.

[0003] The utility model with publication number CN211935943U discloses a filter assembly for secondary water supply equipment, including a secondary water supply tank, a water inlet, a water outlet, a baffle, a water supply channel, a static chamber, a water storage chamber, a sewage outlet, a through groove, a mounting plate, and a composite filter layer. When the tap water enters the static chamber, it is blocked by the baffle, and the liquid level slowly rises, so that the tap water can be static in the static chamber, reducing the amount of sediment entering the water storage chamber. When the secondary water supply tank is not in operation, the inner wall of the static chamber is cleaned by extending the through groove of an external high-pressure water gun into the static chamber, and the sediment is cleaned and discharged from the sewage outlet. However, the sediment in the above-mentioned static chamber cannot be discharged directly, and it is necessary to extend an external high-pressure water gun into the static chamber to clean it. Utility Model Content

[0004] The purpose of the utility model is to solve the defects in the prior art and provide a secondary water supply tank to reduce the pollution to residents' water.

[0005] To achieve the above object, the utility model provides a secondary water supply tank, comprising a tank body, a water inlet, a first water outlet and a second water outlet arranged on the tank body;

[0006] The box body is provided with a partition for dividing the box body into an upper and lower layer, and the first water outlet and the second water outlet are respectively located on the upper and lower sides of the partition; the partition is provided with a plurality of water suction pipes for connecting the upper and lower layers of the box body, and the water suction pipes are in an inverted U shape, which can prevent sediment from clogging the water suction port.

[0007] Specifically, the box body in the utility model is divided into two layers by a partition, the upper layer is a water layer for residents, and the lower layer is a water layer for property work. The water inlet and the first water outlet are located in the water layer for residents, and the second water outlet is located in the water layer for property work, such as washing the floor, watering plants, etc. A number of water suction pipes are arranged on the partition.

[0008] When water is filled into the box through the water inlet, the water first enters the residential water layer. When the water is over the suction pipe, it enters the property work water layer through the suction pipe until the box is full of water. Due to the long-term water storage, pollutants in the water such as mud, rust, etc. are naturally deposited on the partition. When the property needs working water (such as washing the floor, watering plants, etc.), open the second water outlet. Since the suction pipe is set in an inverted U shape, its inlet end is close to the partition, the sediment on the partition can be absorbed into the property work water layer and discharged from the second water outlet, so that the residential water layer can achieve the purpose of self-cleaning and reduce the pollution of residential water. Since the property work water (such as washing the floor, watering plants, etc.) is a daily work, the water is used many times, the amount is large, and the time is long. Each property water work is a cleaning of the secondary water supply tank, thereby achieving the purpose of self-cleaning of the water supply tank. The first water outlet is set on the side wall of the box body at a certain height between the partition and the residential water supplied through the first water outlet, and the pollutants in the water are relatively few. At the same time, since the second water outlet discharges water during daily property water use, it absorbs pollutants on the partition from time to time, which can reduce pollutants discharged from the first water outlet. There is no need to increase the time of cleaning operations, the workload, or the cost of cleaning the secondary water supply tank. During daily property water use (such as washing the floor, watering plants, etc.), the secondary water supply tank is naturally cleaned.

[0009] Optionally, the water suction pipes are evenly arranged on the partition.

[0010] Optionally, the density of the water suction pipe distribution is a≥1 / m 2 Considering the production cost comprehensively, the optimal density of the water suction pipe distribution is 1 / m 2 .

[0011] Optionally, a cleaning brush is further provided in the box, and the cleaning brush is located between the partition and the bottom plate of the box.

[0012] When using water for property work (such as washing the floor, watering plants), open the second water outlet, and the pollutants on the bottom plate of the box will be sucked out when the water comes out. At the same time, the cleaning brush can be pushed and pulled back and forth from time to time to stir the pollutants on the bottom plate of the box and discharge them through the second water outlet, thereby further achieving the goal of cleaning the secondary water supply tank.

[0013] Optionally, the secondary water supply tank further includes a manual push rod, which passes through the side wall of the tank body and is connected to a cleaning brush.

[0014] Optionally, the second water outlet is located below the partition and is provided on the bottom plate of the box body to prevent pollutants from being deposited on the bottom plate of the box body.

[0015] Optionally, a drain trough is provided on the bottom plate of the box body, and the second water outlet is provided below the drain trough.

[0016] Beneficial effects:

[0017] In the utility model, the box body is divided into two layers by a partition, the upper layer is a water layer for residents, and the lower layer is a water layer for property work. The water inlet and the first water outlet are located in the water layer for residents, and the second water outlet is located in the water layer for property work, such as washing the floor, watering plants, etc. A plurality of water suction pipes are arranged on the partition.

[0018] When water is filled into the box through the water inlet, the water first enters the residential water layer. When the water is over the suction pipe, it enters the property work water layer through the suction pipe until the box is full of water. Due to the long-term water storage, pollutants in the water such as mud, rust, etc. are naturally deposited on the partition. When the property needs working water (such as washing the floor, watering plants, etc.), open the second water outlet. Since the suction pipe is set in an inverted U shape, its inlet end is close to the partition, the sediment on the partition can be absorbed into the property work water layer and discharged from the second water outlet, so that the residential water layer can achieve the purpose of self-cleaning and reduce the pollution of residential water. Since the property work water (such as washing the floor, watering plants, etc.) is a daily work, the water is used many times, the amount is large, and the time is long. Each property water work is a cleaning of the secondary water supply tank, thereby achieving the purpose of self-cleaning of the water supply tank. The first water outlet is set on the side wall of the box body at a certain height between the partition and the residential water supplied through the first water outlet, and the pollutants in the water are relatively few. At the same time, since the second water outlet discharges water during daily property water use, it absorbs pollutants on the partition from time to time, which can reduce pollutants discharged from the first water outlet. There is no need to increase the time of cleaning operations, the workload, or the cost of cleaning the secondary water supply tank. During daily property water use (such as washing the floor, watering plants, etc.), the secondary water supply tank is naturally cleaned. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the description of the present utility model, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present utility model based on the specific content of the technical solution.

[0026] In the description of the present invention, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples" or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0027] See also Figure 1 and 2 According to an embodiment of the utility model, a secondary water supply tank comprises a tank body 1, a water inlet 2, a first water outlet 3 and a second water outlet 4 arranged on the tank body 1;

[0028] The box body 1 is provided with a partition 5 for dividing the box body 1 into two layers, and the first water outlet 3 and the second water outlet 4 are respectively located on the upper and lower sides of the partition 5; the partition 5 is provided with a plurality of water suction pipes 6 for connecting the upper and lower layers of the box body 1, and the water suction pipes 6 are inverted U-shape.

[0029] Specifically, the box body 1 is divided into two layers by a partition 5, the upper layer is a residential water layer, and the lower layer is a property water layer. The water inlet 2 and the first water outlet 3 are located in the residential water layer, and the second water outlet 4 is located in the property water layer. Several water suction pipes 6 are arranged on the partition 5.

[0030] When water is filled into the box body 1 through the water inlet 2, the water first enters the residential water layer, and when the water submerges the suction pipe 6, it enters the property water layer through the suction pipe 6 until the box body 1 is full of water. Since the secondary water supply tank needs to store water for many years, pollutants in the water such as mud, rust, etc. are naturally deposited on the partition 5. When the property needs working water (such as washing the floor, watering plants, etc.), the second water outlet 4 is opened. Since the suction pipe 6 is set in an inverted U shape, its inlet end is adjacent to the partition 5, and the sediment on the partition 5 can be absorbed into the property water layer and discharged at the second water outlet 4, so that the residential water layer can achieve the purpose of self-cleaning and reduce the pollution of residential water. Since the property working water (such as washing the floor, watering plants, etc.) is a daily work, the water is used many times, the amount is large, and the time is long. Each property water work is a cleaning of the secondary water supply tank, thereby achieving the purpose of self-cleaning of the water supply tank.

[0031] The first water outlet 3 is set on the side wall of the box body 1 at a certain height from the partition 5. The water for residents supplied through the first water outlet 3 has relatively few pollutants in the water. At the same time, since the second water outlet 4 discharges water during daily property water use, the pollutants on the partition 5 are sucked away from time to time, which can reduce the pollutants discharged from the first water outlet 3. There is no need to increase the time of the cleaning operation, the work intensity, or the cost of cleaning the secondary water supply tank. During the daily property water use (such as washing the floor, watering plants, etc.), the secondary water supply tank is naturally cleaned.

[0032] If vertical water absorption holes are directly set on the partition 5, the deposition of pollutants will cause the water absorption holes to be blocked. At the same time, water from the residents' water layer will naturally flow into the property water layer. At this time, the suction force that sucks the sediment on the partition 5 into the property water layer is relatively small. Compared with the vertical water absorption holes, an inverted U-shaped water absorption pipe 6 is set. The deposition of pollutants will not block the water absorption holes. Water entering the property water layer needs to pass through the inverted U-shaped water absorption pipe 6. The suction force that sucks the sediment on the partition 5 into the property water layer is relatively large, and the suction area is large.

[0033] See also Figure 1 and 2 In some embodiments of the present invention, the water suction pipe 6 is evenly arranged on the partition 5.

[0034] See also Figure 1 and 2 In some embodiments of the present invention, the density of the water suction pipe 6 distribution is a≥1 / m 2Taking into account the manufacturing cost, the density of the water suction pipe 6 is preferably 1 / m 2 .

[0035] See also Figure 1 and 2 In some embodiments of the utility model, a cleaning brush 7 is further provided in the box body 1, and the cleaning brush 7 is located between the partition 5 and the bottom plate of the box body 1. The cleaning brush 7 is connected to the stirring rod 8, and the side wall of the box body 1 is sealed and connected to the stirring rod 8 through a water seal ring 9. The pollutants stirred by the cleaning brush 7 are also in the property water layer, and the pollutants after stirring will not affect the residents' water layer.

[0036] When using water for property work (such as washing the floor, watering plants), open the second water outlet 4, and when the water comes out, the pollutants on the bottom plate of the box body 1 are sucked out. The stirring rod 8 can be pushed and pulled regularly to drive the bristles of the cleaning brush 7 to move, stirring the pollutants on the bottom plate of the box body 1, and then discharged through the second water outlet 4, further achieving the goal of cleaning the water tank. When stirring is not needed at ordinary times, the stirring rod 8 is pushed to the deepest part of the box body 1, that is, the end of the box body adjacent to the water inlet 2.

[0037] See also Figure 1 and 2 In some embodiments of the present invention, the second water outlet 4 is located below the partition 5 and is provided on the bottom plate of the box body 1 to prevent pollutants from being deposited on the bottom plate of the box body 1.

[0038] See also Figure 1 and 2 In some embodiments of the utility model, a drain trough 10 is provided on the bottom plate of the box body 1, and the second water outlet 4 is provided below the drain trough 10. The stirring rod 8 pushes the pollutants into the drain trough 10, and the pollutants are discharged through the second water outlet 4.

[0039] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
