Problems solved by technology

[0003] The existing patent numbers CN104060649B and CN209873945U both propose variable frequency constant pressure water supply components. When supplying water, the pipeline is usually extended directly into the water. However, during the movement of the ship, as the position changes, the pressure on the water surface will increase and decrease. It acts directly on the pipeline, and the water flow is flowing relative to the pipeline, which will increase the pressure effect. After the ship has been running for a long time, the pipeline is likely to be broken due to the excessive pressure difference between the inside and outside of the pipeline, etc.

Embodiment 1

[0042] Example 1: Please refer to Figure 1-4 , a frequency conversion constant pressure water supply assembly, including an electric control cabinet 1, a water pump group 2, an air pressure tank 3, a water supply pipe 4, a water collection mechanism 5, a telescopic mechanism 6 and a water storage tank 7, and the inside of the electric control cabinet 1 is fixedly installed with electric control system and ABB frequency converter, the electric control cabinet 1 is electrically connected to the water pump group 2, the water pump group 2, the air pressure tank 3 and the water supply pipe 4 are all arranged on the left side of the electric control cabinet 1, and the water inlet end of the water supply pipe 4 is connected to the water storage The water tank 7 is fixedly connected and communicated. The interior of the water storage tank 7 is fixedly equipped with a filter mechanism 10. The filter mechanism 10 adopts a reverse osmosis membrane filter mechanism. It is fixedly install...

Embodiment 2

[0046] Example 2: Please refer to Figure 5-6 , on the basis of Embodiment 1, rubber sleeves 13 are sleeved at the twists and turns of the outer wall of bellows 56. When the bellows 56 is stretched out, the rubber sleeve 13 will also be stretched out, thereby having The effect of accommodating part of the water through the through hole 14, and then when the water collecting mechanism 5 stops using, etc., the rubber sleeve 13 also shrinks during the shrinkage process of the bellows 56, and the water stored in it is squeezed out. Water is used to flush the inner wall of the bellows 56. Through the setting of the rubber sleeve 13, the rubber sleeve 13 is fixedly connected to the folds of the outer wall of the bellows 56, thereby increasing the strength of the fragile position of the bellows 56, and then the rubber sleeve 13 is connected with the connecting rod B15 During the stretching process, part of the water entering the bellows 56 will be stored, and then when the water col...

Embodiment 3

[0049] Example 3: Please refer to Figure 7-8 , on the basis of Embodiment 2, the bottom surface of the connecting pipe 55 is fixedly connected with the clean water tank 17, the inside of the clean water tank 17 is hollow and communicates with the connecting pipe 55, and the bottom surface of the scraper 16 is provided with five water inlet grooves A18, and the scraper Inside 16, a water inlet tank B19 is provided above the water inlet tank A18. The water inlet tank B19 is connected to the five water inlet tanks A18. The top surface of the water inlet tank B19 is provided with a water outlet hole 20. The inner wall of the water outlet hole 20 is fixedly connected with a water delivery pipe 21. The end of the water delivery pipe 21 away from the water outlet hole 20 is fixedly connected and communicated with the clean water tank 17, and the inner wall of the water inlet tank A18 is fixedly equipped with a filter screen 22. After the water enters the bellows 56 and the bottom pla...

Abstract

The invention relates to the technical field of water supply, and discloses a variable frequency constant pressure water supply assembly, including an electric control cabinet, a water pump group, a pressure tank, a water supply pipe, a water collection mechanism, a telescopic mechanism and a water storage tank, and the inside of the electric control cabinet is fixedly installed with The electric control system, ABB frequency converter, water pump unit, air pressure tank and water supply pipe are all arranged on the left side of the electric control cabinet. The water inlet end of the water supply pipe is fixedly connected and communicated with the water storage tank, and a filter mechanism is fixedly installed inside the water storage tank. The filter mechanism adopts the reverse osmosis membrane filter mechanism. The water collection mechanism is fixedly installed on the left side of the water storage tank. It sinks, thereby expanding the water collection space, and its deformation range can be freely changed according to the strength of the external water pressure, which has the effect of automatically balancing the internal and external pressure. Compared with the existing water collection mechanism, it can avoid external water pressure Added the benefit of being too large to cause damage to the water collection mechanism.

Description

technical field [0001] The invention relates to the technical field of water supply, in particular to a variable frequency constant pressure water supply assembly. Background technique [0002] Frequency conversion constant pressure water supply equipment is a new type of energy-saving water supply equipment. The frequency conversion constant pressure water supply equipment is a high-tech energy-saving water supply device with electromechanical integration, which uses the most advanced microcomputer control technology and combines frequency conversion speed regulator and motor water pump. The existing frequency conversion constant pressure water supply equipment is also widely used on medium and large ships. [0003] Existing patent numbers CN104060649B and CN209873945U both proposed variable frequency constant pressure water supply components. When supplying water, the pipeline is usually extended directly into the water. However, during the movement of the ship, as the pos...
