Description

Technical Field

[0001] The present invention belongs to the technical field of secondary water supply, and particularly relates to a tower-type water supply device. Background Art

[0002] Secondary water supply refers to the form in which units or individuals store, pressurize the urban public water supply or self-built water supply, and then supply it to users or for self-use through pipelines. Secondary water supply is mainly established to compensate for the lack of pressure in the municipal water supply pipeline and ensure the water use of people living on high floors. Whether the secondary water supply facilities are constructed and designed according to regulations and the quality of construction are directly related to the water quality, water pressure and water supply safety of secondary water supply, and are closely related to the normal and stable life of the people.

[0003] Common secondary water supply devices include cylindrical water tanks indirectly installed on the roof ground through support frames. This type of water supply device is also a well-known tower-type water supply device in the industry. According to industry regulations, each water tank should be cleaned at least once every six months, but because each cleaning of the water tank requires a long time of water cut-off, it cannot be effectively implemented.

[0004] In addition, compared with the raw water supply, the water quality of secondary water supply is more easily polluted. Rust, algae, eggs and other floating pollutants usually occur in the water tank for various reasons. Even more seriously, due to accidental reasons, animal corpses and fecal pollutants such as cockroaches and mice will also appear. If the polluted secondary water supply is used for a long time, it will cause harm to the physical health of the human body. Therefore, it is necessary to monitor the water quality of the tap water in the water tank in real time.

[0005] At present, people usually monitor whether the water quality is polluted by manually checking regularly. On the one hand, the light inside the water tank is dim, and the polluted water quality cannot be effectively observed by the naked eye. On the other hand, due to the long monitoring time interval, it also cannot detect the polluted water quality in time. Although there is also a technology for detecting water quality pollution by a turbidimeter in the prior art, such as the portable turbidimeter disclosed in the patent document with the publication number of CN213715201U, since the water level (water surface) in the water tank will fluctuate when there is water inlet and outlet, affected by the water surface fluctuation, the floating pollutants usually gather around the water surface. And this type of turbidimeter is usually fixedly installed at the low water level inside the water tank. It is possible that there is no pollution in its monitoring area, but the high water level area has been polluted. Therefore, this technology still cannot effectively and timely detect the pollution of the water quality.

[0006] Furthermore, when the water quality is found to be polluted, the water tank also needs to be cleaned in time, but cleaning the water tank still requires a long time of water cut-off, so there is also a technical problem of affecting the normal water use of residents. Summary of the Invention

[0007] The object of the present invention is to provide a tower-type water supply device, which can specifically draw water from the water surface edge near the inner wall of the water tank for real-time detection, and can provide temporary water supply for residents when the water tank needs to be cleaned, thereby solving the technical problems that the prior art cannot effectively and timely detect water quality pollution and the water supply needs to be stopped for a long time when cleaning the water tank.

[0008] To achieve the above object, the technical solution adopted by the present invention is as follows:

Both ends of the transfer hard pipe are respectively connected to the temporary water inlet assembly and the connector, and the sampling pump is installed on the transfer hard pipe.

[0017] Both the floating body and the sampling hard pipe are arc-shaped structures adapted to the inner wall of the main water tank.

[0018] The temporary water supply container includes a top plate, a telescopic upper cylinder, and a lower cylinder. The upper cylinder is made of food-grade plastic, and the lower cylinder is made of stainless steel plate. A conical groove is provided in the middle of the bottom of the lower cylinder.

The upper cylinder is hermetically fixed between the top plate and the lower cylinder. The flushing assembly is fixed to the top plate and can flush the inner wall of the temporary water supply container. The temporary water inlet assembly is connected to the upper part of the upper cylinder, and the temporary water outlet assembly is connected to the bottom of the lower cylinder.

The temporary water outlet assembly includes a drain pipe, a temporary water outlet hose, a return pipe, solenoid valves D, E, F, and G. Among them, the water inlet pump is installed at the water inlet end of the main water inlet pipe. The water inlet end of the temporary water inlet pipe is connected between the water inlet pump and the solenoid valve A. The water outlet end of the temporary water inlet pipe communicates with the edge sampling assembly and the upper cylinder respectively.

[0022] A water level gauge connected to the controller is also provided in the temporary water supply container.

[0023] Adopting the above technical solution, the beneficial technical effects of the present invention are as follows:

[0024] 1. The tower-type water supply device described in the present invention is provided with a temporary water supply device that can supply water temporarily below the main water tank, and the temporary water supply device can be used in cooperation with the edge sampling assembly to perform real-time detection of water quality. Since the edge sampling assembly is floatingly arranged at the inner wall of the main water tank and samples at regular intervals, it can specifically draw water from the water surface edge near the inner wall of the water tank for detection, which not only improves the accuracy of detection but also makes the detection of water quality more timely. Moreover, through the cooperation of the temporary water supply device and the corresponding water inlet and outlet assemblies, when the water tank needs to be cleaned, the temporary water supply device can replace the main water tank to supply water temporarily, avoiding inconvenience to residents caused by water cut-off. In addition, the temporary water supply container is located below the main water tank, and the height of the temporary water supply container is adjustable, which also enables the main water tank to better hide the temporary water supply container during normal water supply, reducing the influence of the external environment on the temporary water supply container, and thus is beneficial to improving the service life of the temporary water supply container. In addition, through the flushing assembly, the temporary water supply container can be cleaned before temporary water supply to ensure better cleanliness of the temporary water supply container.

[0025] 2. The present invention sets the volume of the temporary water supply container to 1 - 4 cubic meters, which is conducive to ensuring the temporary water use needs of residents.

[0026] 3. The present invention uses a floating body, a sampling hard pipe, a connecting hose, a connecting hard pipe, a sampling pump and a connector as the edge sampling assembly. Under the dual limiting effects of the fluctuations of the connecting hose and the water surface in the main water tank, the floating body can be close to the inner wall of the main water tank, so that the sampling hard pipe can specifically obtain edge water samples from both ends of the floating body for detection, which is conducive to improving the accuracy of detection.

[0027] 4. The present invention sets both the floating body and the sampling hard pipe as arc-shaped structures adapted to the inner wall of the main water tank, which is conducive to obtaining the outermost edge water samples and thus getting more accurate detection results.

[0028] 5. The present invention uses a top plate, a telescopic upper cylinder and a lower cylinder as the temporary water supply container, so that the height and volume of the temporary water supply container can be adjusted accordingly, and it has the advantages of stable temporary water supply and convenient adjustment.

[0029] 6. The present invention fixes the upper cylinder to the top plate through clamping plates, bolts and gaskets, which has the advantages of good stability, easy disassembly, installation and maintenance. And strengthening ribs are arranged at the bottom of the lower cylinder, which makes the structural strength of the lower cylinder higher and can be used for a long time without deformation.

[0030] 7. The present invention constitutes each water inlet and outlet assembly through corresponding pipes and solenoid valves, which not only has the advantages of simple structure and convenient control, but also is convenient to switch between the main water tank and the temporary water supply container.

[0031] 8. The present invention is equipped with multiple flushing nozzles to flush the temporary water supply container from multiple directions, which is conducive to improving the flushing effect.

[0032] 9. The present invention uses a water level gauge to monitor the water level in the temporary water supply container in real time, and can replenish water in time when the water volume is insufficient to ensure the water use needs of residents. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0037] Embodiment 1

[0038] The present invention provides a tower-type water supply device, which can supply water by using a temporary water supply device when the water tank 1 needs to be cleaned every six months or when it is detected in real time that the water quality is polluted, so as to ensure the water supply demand of residents without water interruption. As Figure 1 、 2 shown, it includes a main water tank 1, a controller 2, a support frame 3, a support platform 4, a feed pump 5, a main water inlet assembly 6, a main water outlet assembly 7, a temporary water supply device, an edge sampling assembly 8 and a turbidity detector 9. The temporary water supply device includes a temporary water supply container 10, a temporary water inlet assembly 11, a temporary water outlet assembly 12 and a flushing assembly 13; wherein,

[0039] The support frame 3 is mainly composed of multiple columns fixed on the roof ground. The support frame 3 is in a column shape or a frustum shape as a whole, and is used to support the main water tank 1.

[0040] The main water tank 1 is of a cylindrical structure with a volume of 5 - 30 tons. The main water tank 1 is fixed at the upper end of the support frame 3. After being fixed, the main water tank 1 is at a certain distance from the roof ground to facilitate the installation space provided by the temporary water supply device. There are multiple support platforms 4, all of which are fixed at the lower end of the support frame 3 and are used to support the temporary water supply container 10. The feed pump 5 is connected to the main water inlet assembly 6. The main water inlet assembly 6 is installed at the upper part on one side of the main water tank 1. The feed pump 5 can supplement tap water into the main water tank 1 through the main water inlet assembly 6. The main water outlet assembly 7 is installed at the lower part on the other side of the main water tank 1 and is used to supply water to residents.

[0041] The temporary water supply container 10 is installed between the main water tank 1 and the support platform 4 through the support frame 3, and its volume is 1 - 4 cubic meters, which can be specifically set according to the number of water supply residents. The temporary water supply container 10 adopts a telescopic structure so that its height can be adjusted, and thus its volume can be adjusted. In addition, a conical groove is provided in the middle of the bottom of the temporary water supply container 10 to facilitate the installation of the turbidity detector 9 in the conical groove for water quality turbidity detection.

[0042] It should be noted that the upper end of the temporary water supply container 10 is fixed to the upper part of the support frame 3, and the lower end of the temporary water supply container 10 is detachably fixed to the middle part of the support frame 3. At this time, the temporary water supply container 10 is in a contracted state with the smallest volume, which is suitable for sampling for water quality turbidity detection. When the fixing structure between the lower end of the temporary water supply container 10 and the middle part of the support frame 3 is removed, the lower end of the temporary water supply container 10 can be lowered onto the support platform 4, so that the temporary water supply container 10 is in an expanded state. At this time, the temporary water supply container 10 has the largest volume, which is suitable for using the temporary water supply container 10 for water supply, and thus facilitates the cleaning of the main water tank 1.

[0043] Furthermore, the structure of the temporary water supply container 10 can be: including a circular top plate 20, a telescopic upper cylinder 21 and a lower cylinder 22. Among them, the upper cylinder 21 is made of food-grade plastic, and the lower cylinder 22 is made of stainless steel plate. The conical groove is provided in the middle of the bottom of the lower cylinder 22. The top plate 20 is fixed to the upper part of the support frame 3, and the lower part of the lower cylinder 22 is installed on the support frame 3 through a detachable hanging buckle. The upper cylinder 21 is hermetically fixed between the top plate 20 and the lower cylinder 22. When the hanging buckle is loosened, the lower cylinder 22 can be lowered onto the support platform 4. At this time, the upper cylinder 21 is unfolded, which is equivalent to increasing the height and volume of the temporary water supply container 10, and can be used to replace the main water tank 1 for temporary water supply, facilitating the cleaning of the main water tank 1.

[0044] Preferably, for the convenience of disassembly and assembly of the temporary water supply container 10, the upper end of the upper cylinder 21 is fixed to the top plate 20 through a clamping plate, bolts and gaskets, that is, the upper cylinder 21 and the top plate 20 can be separated by loosening the bolts. To improve the stability of the temporary water supply container 10, in this embodiment, reinforcing ribs are also provided at the bottom of the lower cylinder 22.

[0045] In addition, a water level gauge 39 connected to the controller 2 is also provided in the temporary water supply container 10. Through the water level gauge 39, the water level in the temporary water supply container 10 can be monitored in real time to meet the real-time water supply needs of residents. The flushing assembly 13 is fixed to the top plate 20 and can flush the inner wall of the temporary water supply container 10. The temporary water inlet assembly 11 is connected to the upper part of the upper cylinder 21, and the temporary water outlet assembly 12 is connected to the bottom of the lower cylinder 22.

[0046] One end of the temporary water inlet assembly 11 is connected to the upper part of the temporary water supply container 10, and the other end is connected to the water inlet pump 5; one end of the temporary water outlet assembly 12 is connected to the middle of the bottom of the temporary water supply container 10, and the other end is respectively connected to the upper parts of the main water outlet assembly 7 and the main water tank 1; the flushing assembly 13 is fixed to the upper end of the temporary water supply container 10 and is connected to the water inlet pump 5 through the temporary water inlet assembly 11. Among them, the flushing assembly 13 is used to flush the temporary water supply container 10 when the temporary water supply container 10 replaces the main water tank 1 to supply water, and the temporary water inlet assembly 11 and the temporary water outlet assembly 12 are used to supplement and output tap water when the temporary water supply container 10 replaces the main water tank 1 to supply water. When the main water tank 1 needs to be cleaned every six months, or when it is detected that the turbidity of the water quality in the main water tank 1 exceeds the national standard and pollution occurs and the main water tank 1 needs to be cleaned, the temporary water supply container 10 can be cleaned, tap water can be supplemented and output through the cooperation of the flushing assembly 13, the temporary water inlet assembly 11 and the temporary water outlet assembly 12, so as to achieve the purpose of not stopping water during the cleaning of the main water tank 1.

[0047] One end of the edge sampling assembly 8 is floatingly arranged at the inner wall of the main water tank 1, and the other end is communicated with the temporary water supply container 10 through the temporary water inlet assembly 11. The edge sampling assembly 8 can sample at periodic intervals, and the interval time can be 30 - 60 minutes. Through the edge sampling assembly 8, the water sample at the edge of the water surface in the main water tank 1 where floating pollutants are likely to gather can be transported to the conical tank of the temporary water supply container 10 for turbidity detection by the turbidity detector 9. It should be noted that the edge sampling assembly 8 can rise and fall with the rise and fall of the water level, and it can obtain a quantitative water sample by setting the sampling time. The quantitative water sample is preferably sufficient to meet the requirements of the turbidity detector 9. For example, the quantitative water sample each time can be 5 - 10 L, etc.

[0048] The controller 2 is installed in the middle or upper part of the support frame 3 and is used to control the actions of the water inlet pump 5, the main water inlet assembly 6, the main water outlet assembly 7, the edge sampling assembly 8, the turbidity detector 9, the temporary water inlet assembly 11, the temporary water outlet assembly 12 and the flushing assembly 13 respectively. It should be noted that the controller 2 can be an existing conventional PLC controller 2, and the turbidity detector 9 is both a conventional commercially available product and can also be a portable turbidity meter in the patent documents cited in the background technology. In addition, the turbidity detector 9 generally includes a detection unit and a processing unit. The detection unit is arranged in the conical tank for detecting the turbidity of the water quality. The processing unit can be integrated into the controller 2 or can be separately arranged on the support frame 3 and connected to the controller 2.

[0049] In this embodiment, the main water inlet assembly 6, the main water outlet assembly 7, the temporary water inlet assembly 11 and the temporary water outlet assembly 12 are mainly composed of pipelines and solenoid valves, and the flushing assembly 13 is mainly composed of a spray head, a pipeline and a solenoid valve. Their specific structures are as follows:

[0050] The main water inlet assembly 6 includes a main water inlet pipe 23 and a solenoid valve A 24 installed on the main water inlet pipe 23. The main water outlet assembly 7 includes a main water outlet pipe 25 and a solenoid valve B 26 installed on the main water outlet pipe 25. The temporary water inlet assembly 11 includes a temporary water inlet pipe 27 and a solenoid valve C 28 installed on the temporary water inlet pipe 27. The temporary water outlet assembly 12 includes a drain pipe 29, a temporary water outlet hose 30, a return pipe 31, a solenoid valve D 32, a solenoid valve E 33, a solenoid valve F 34, and a solenoid valve G 35. Among them, the water inlet pump 5 is installed at the water inlet end of the main water inlet pipe 23. The water inlet end of the temporary water inlet pipe 27 is connected between the water inlet pump 5 and the solenoid valve A 24. The water outlet end of the temporary water inlet pipe 27 communicates with both the edge sampling assembly 8 and the upper cylinder 21. The drain pipe 29 is connected to the bottom of the lower cylinder 22. The solenoid valve D 32 is installed on the drain pipe 29. The water inlet end of the temporary water outlet hose 30 is connected to the drain pipe 29 between the solenoid valve D 32 and the lower cylinder 22. The water outlet end of the temporary water outlet hose 30 is connected to the main water outlet pipe 25 behind the solenoid valve B 26. The solenoid valves E 33 and F 34 are respectively installed at both ends of the temporary water outlet hose 30. The water inlet end of the return pipe 31 is connected to the temporary water outlet hose 30 between the solenoid valves E 33 and F 34. The water outlet end of the return pipe 31 is connected to the upper part of the main water tank 1. The solenoid valve G 35 is installed on the return pipe 31.

[0051] The flushing assembly 13 includes a flushing pipe 36, a solenoid valve H 37, and a plurality of flushing nozzles 38. The flushing pipe 36 is fixed between the top plate 20 and the main water tank 1. The solenoid valve H 37 is installed on the flushing pipe 36. The plurality of flushing nozzles 38 are installed on the top plate 20 and respectively face different areas of the inner wall of the temporary water supply container 10. The water inlet end of the flushing pipe 36 is connected to the temporary water inlet pipe 27 in front of the solenoid valve C 28. The water outlet ends of the flushing pipe 36 are respectively connected to the plurality of flushing nozzles 38.

[0052] In this embodiment, the controller 2 controls the opening and closing of the above-mentioned solenoid valves, thereby implementing the on-off of the main water inlet assembly 6, the main water outlet assembly 7, the temporary water inlet assembly 11, the temporary water outlet assembly 12, and the flushing assembly 13, so as to meet the uninterrupted water supply for residents.

[0053] The implementation principle of this embodiment is as follows:

[0054] When the main water tank 1 supplies water normally, the lower cylinder body 22 is hung in the middle of the support frame 3 through the hanging fasteners, and the temporary water supply container 10 is located above the support platform 4. At this time, the temporary water supply container 10 is in a contracted state with the smallest volume. Then, the controller 2 controls the edge sampling assembly 8 to sample from the water surface edge at intervals and deliver the sample to the temporary water supply container 10 for the turbidity detector 9 to detect. When the detection result shows that the water quality is normal, it indicates that the tap water in the water tank 1 is normal without pollution. The controller 2 controls the temporary water outlet assembly 12 to convey the sampled water back to the main water tank 1 for reuse to avoid waste. When the detection result shows water quality pollution, the controller 2 controls the edge sampling assembly 8 to stop sampling, controls the turbidity detector 9 to stop detecting, controls the temporary water outlet assembly 12 to discharge the polluted water, and at the same time controls the main water inlet assembly 6 to stop the water inlet of the main water tank 1 and controls the main water outlet assembly 7 to stop discharging water. Then, the hanging fasteners are loosened, and the bottom of the temporary water supply container 10 is adjusted to move downward onto the support platform 4 to increase the volume of the temporary water supply container 10. Then, the water inlet pump 5 is controlled to supply water to the flushing assembly 13, and multiple flushing nozzles 38 cooperate to flush the inner wall of the temporary water supply container 10 in multiple directions. After the flushing is completed, the flushing water is discharged. Finally, the water inlet pump 5 and the temporary water inlet assembly 11 are controlled to inject water into the temporary water supply container 10, and the temporary water outlet assembly 12 is controlled to replace the main water outlet assembly 7 to supply water to the residents, so as to ensure the continuous water use demand of the residents. During the period when the temporary water supply container 10 supplies water, the main water tank 1 can be cleaned. Generally speaking, this embodiment can specifically take water from the water surface edge near the inner wall of the water tank 1 for real-time detection, and can provide temporary water supply for residents when the water tank 1 needs to be cleaned, having the advantages of high detection accuracy, timely detection, and continuous water supply during the cleaning of the water tank 1.

[0055] Embodiment 2

[0056] In this embodiment, the edge sampling assembly 8 is further defined on the basis of Embodiment 1. As Figures 1-3As shown in the figure, the edge sampling assembly 8 includes a floating body 14, a sampling hard pipe 15, a connecting hose 16, a connecting hard pipe 17, a sampling pump 18 and a connector 19. Both the floating body 14 and the sampling hard pipe 15 are arc-shaped structures adapted to the inner wall of the main water tank 1. The floating body 14 is floatingly arranged on the water surface in the main water tank 1, and the sampling hard pipe 15 is hidden in the floating body 14. The two ends of the sampling hard pipe 15 extend from both ends of the floating body 14 and are exactly below the water surface, so that the sampling hard pipe 15 can obtain effective water samples from two directions; the connector 19 is fixed in the middle of the main water tank 1. One end of the connecting hose 16 extends into the floating body 14 and is connected to the middle of the sampling hard pipe 15 through a tee joint, and the other end of the connecting hose 16 is connected to the connector 19; the two ends of the connecting hard pipe 17 are respectively connected to the temporary water inlet assembly 11 and the connector 19, and the sampling pump 18 is installed on the connecting hard pipe 17 and connected to the controller 2. Starting the sampling pump 18 can transport the water in the main water tank 1 to the temporary water supply container 10 through the sampling hard pipe 15, the connecting hose 16, the connector 19 and the connecting hard pipe 17 for turbidity detection.

[0057] It should be noted that the length of the connecting hose 16 is about half of the height of the main water tank 1. Since the connector 19 is arranged in the middle of the main water tank 1, the connecting hose 16 can limit the floating body 14 near the inner wall of the water tank 1. Also, because the water surface in the main water tank 1 itself has fluctuations, the floating body 14 can be further fluctuated to the inner wall of the main water tank 1 through the fluctuations. Based on this, water can be taken from the water surface edge near the inner wall of the water tank 1 for real-time detection, so as to obtain more accurate detection results and effectively ensure the water use safety of residents.

[0058] The above is only the specific implementation manner of the present invention. Any feature disclosed in this specification, unless specifically described, can be replaced by other equivalent or similar-purpose alternative features; all the features disclosed, or all the steps in any method or process, except for mutually exclusive features and / or steps, can be combined in any way.
