Description

Technical Field

[0001] The utility model relates to cleaning of a water tank with secondary water supply, in particular to a dual-supply cleaning universal drainage device used for draining water from a water tank. Background Art

[0002] In many older residential communities, the water supply systems of high-rise buildings often rely on rooftop water tanks. These tanks use pumps to transport municipal water to high-rise locations to meet the daily water needs of residents on upper floors. To ensure the safety of residents' water supply, regular and thorough cleaning of these rooftop water tanks is crucial. Before cleaning, the pumps must be turned off and the water in the tanks must be completely drained. Currently, the drainage method is relatively simple: simply open the drain valve, allowing the water in the tank to flow through the roof's drainage system into the downspouts and ultimately out.

[0003] However, due to the generally outdated infrastructure in these older communities, drainage facilities present numerous problems. For example, rainwater and sewage often mix within the drainage system, downspouts can become damaged or clogged, and roof waterproofing can be compromised. Furthermore, some roofs lack drainage channels. These factors make it highly susceptible to secondary hazards such as backflow and leaks when draining water tanks using existing technology, leading to direct financial losses for residents.

[0004] Furthermore, the drainage channel within the pump house presented problems. The channel might be too shallow, or the distance between the tank's drain valve and the channel might be too far. Using existing drainage technology, the splashing and spraying of water could pose a safety hazard to the various electrical equipment within the pump house. It could also easily lead to mold and bacterial growth, compromising the sanitation of the entire water supply system and the health of residents. Utility Model Content

However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0027] In order to fully understand the present invention, detailed steps and detailed structures will be provided in the following description to illustrate the technical solution of the present invention. The preferred embodiments of the present invention are described in detail below. However, in addition to these detailed descriptions, the present invention may also have other implementation methods.

[0028] Reference Figure 1 As shown, the utility model provides a dual-supply (secondary water supply, referred to as dual-supply) cleaning universal drainage device for water tank drainage. The water tank is provided with a drainage joint, and the drainage joint is provided with a drainage valve. The dual-supply cleaning universal drainage device consists of a universal joint 10 and a multi-section drainage belt 20.

[0029] Universal joint 10

[0030] like Figure 1-Figure 2 As shown, the universal joint 10 includes a rubber bellows body 11. One end of the rubber bellows body 11 is provided with a first connector 12 that is sleeved onto the drain joint. The first connector 12 is fixedly connected to the drain joint via a first clamp 31. The other end of the rubber bellows body 11 is sleeved onto a stepped PE reducer 13, and a third clamp 33 secures the rubber bellows body 11 to the reducer 13.

[0033] The two hoses 21 are connected via a quick-release connector 22, which features an anti-drop lock mechanism to prevent accidental detachment during use. The quick-release connector 22 plugs into the hoses 21 and is secured with a fourth clamp 34. One hose 21 is placed over the reducer 13 and secured with the second clamp 32, while the other hose is connected to the sewer.

[0034] Further reading Figure 3 The quick-release joint 22 is a rotary snap-on joint, which consists of two rotary joints fixed at one end of the two water hoses 21, and a sealing ring 25 is provided on the end face of the rotary joint. The two rotary joints are respectively provided with a rotary slot 23 and a snap 24. After the two rotary joints are docked and connected, they rotate relative to each other, so that the snap 24 of one rotary joint is inserted into the rotary slot 23 of the other rotary joint to complete the locking, so as to connect the two water hoses 21 and extend their length. Through the cooperation of the rotary slot 23 and the snap 24, quick connection and disassembly are achieved. This design not only improves the convenience of operation, but also enhances the reliability of the connection. In actual application, users can quickly replace the water hoses as needed to adapt to different drainage environments and needs. In addition, the structural design of the rotary snap-on joint makes the sealing performance of the water hose connection more superior, effectively preventing water leakage that may occur during high-pressure drainage.

[0035] In another embodiment, a rotation slot 23 and a buckle 24 may be provided on both rotary joints to further improve the stability of the connection between the hoses.

[0036] The above-mentioned first clamp 31, second clamp 32, third clamp 33, and fourth clamp 34 are stainless steel clamps, and one end of the stainless steel clamp is provided with a bolt for adjusting the tightness. The utility model uses a stainless steel clamp with adjustable tightness to connect the rubber bellows body 11 with the first connector 12 and the reducer 13 at both ends, and quickly connects the water hose 21 with the reducer 13 and the quick-release connector 22. In actual operation, it has good sealing and corrosion resistance. The stainless steel material not only ensures the strength and durability of the connector, but also maintains stable performance in various environments, is not easy to rust, and extends the service life of the equipment. By adjusting the bolt, the user can easily adjust the tightness of the clamp according to actual needs, ensure a close fit of the connection parts, and effectively prevent the occurrence of water or air leakage. In addition, the use of stainless steel clamps also simplifies the maintenance and replacement process and improves the convenience of the overall operation.

[0037] The advantages of the universal joint of the utility model are:

[0038] 1. The size of the front interface can be adjusted through the stainless steel clamp to adapt to the size of the water tank drain outlet within a certain range to prevent water leakage due to loose wrapping.

[0039] 2. The flexible joint can be twisted in any direction to adapt to a variety of complex floor and pump room scenarios while still ensuring smooth drainage.

[0040] 3. The universal joint and the water hose can be connected through the replaceable reducer PE pipe. At the same time, the reducer can not only adapt to water hoses of different thicknesses, but also ensure the sealing of the connection.

[0041] The advantages of multi-section drainage belts are:

[0042] 1. The drainage belt is made of canvas with rubber lining inside and waterproof material to avoid water leakage during drainage.

[0043] 2. The material is lightweight, making it more suitable for carrying when climbing.

[0044] 3. When on site, multiple water hoses can be quickly connected through quick-release joints to adapt to high-rise or ultra-long-distance drainage. The quick-release connection of the water hose also makes it easier to disassemble and assemble the water hose.

[0045] The utility model provides a dual-supply cleaning universal drainage device with a light overall weight and convenient disassembly and assembly, which is suitable for water tank cleaning personnel to carry and use during work. It has now been actually applied in water tank cleaning work. After many field tests, it has been found that when cleaning a water tank with difficult drainage, the dual-supply cleaning universal drainage device can be used to directly discharge water from the water tank in unfavorable conditions to a fixed point without passing through the roof and downpipe, which can effectively avoid secondary disasters that are very likely to be caused during drainage and avoid economic losses.
