Description

Technical Field

[0001] The utility model relates to the technical field of degassing constant pressure water replenishment, in particular to a degassing constant pressure water replenishment device. Background Art

[0002] During actual use, the water pressure fluctuation of the constant pressure tank of the existing constant pressure water replenishment vacuum degassing unit is very small, and the water in and out of the constant pressure tank is correspondingly reduced. Most of the water in the constant pressure tank cannot be replaced for a long time, forming dead water. The dead water that is retained for too long is prone to breed microorganisms, causing the water to rot and deteriorate, and causing secondary pollution to the water in the water supply system. In addition, there will be a large amount of adhesion inside the constant pressure tank, which will cause subsequent pipeline blockage. The existing manual cleaning is troublesome, inconvenient, and not clean.

[0003] In response to the above problems, those skilled in the art have made improvements to the existing technology. For example, a constant-pressure water-making vacuum degassing unit with publication number CN212069819U is provided, in which an inner wall cleaning mechanism is provided inside the constant-pressure tank shell, and the inner wall cleaning mechanism includes an electric slide rail, an electric slider and a scraper. The electric slide rail is symmetrically arranged longitudinally on the inner wall of the shell, and the electric slider is installed on the electric slide rail. The scraper includes a first plate body and a second plate body. The upper end of the second plate body is fixedly connected to the edge of the lower end surface of the first plate body, and the second plate body is fixedly connected to the electric slider. The lower end of the second plate body is in contact with the inner wall of the shell. An annular tube is installed on the lower end surface of the first plate body, and the annular tube is provided with a water inlet through hole and evenly arranged water spray holes. The annular ring is located on the inner side of the second plate body, and a longitudinal water inlet pipe is installed at the bottom of the shell, which can clean the inner wall of the shell. However, the above device requires an electric slide rail to be provided on the inner wall of the shell. When impurities adhere to the inner surface of the shell, the gap between the electric slider and the electric slide rail may be blocked, resulting in the inability to drive the slide to move normally, which is still inconvenient to use.

[0004] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

The sliding gear 24 is located on the top turntable 22. The top surface of the top turntable 22 is provided with a locking groove that can cooperate with the sliding gear 24. The locking groove is provided with an electromagnet that can cooperate with the sliding gear 24 (the sliding gear 24 is made of magnetic material). When the sliding gear 24 cooperates with the locking groove, the threaded tube 23 and the top turntable 22 move synchronously. The top surface of the sliding gear 24 is provided with a clamping groove that can cooperate with the driving gear 25. When the clamping groove cooperates with the driving gear 25, the sliding gear 24 disengages from the locking groove.

[0026] See also Figures 1 to 4A sleeve shaft 26 is rotatably provided at the top of the rotating shaft 21, and a counter ratchet is provided on the side wall of one end of the sleeve shaft 26 (the counter ratchet is in the opposite direction of the positive ratchet).

A lifting seat 261 is provided on the sleeve shaft 26, and a second circulation groove that cooperates with the lifting seat 261 is provided on the surface of the sleeve shaft 26 (the cooperation method between the lifting seat 261 and the second circulation groove refers to the bottom slider 231 and the first circulation groove). A horizontal shaft 27 is rotatably provided on both sides of the lifting seat 261, and both ends of the horizontal shaft 27 are rotatably connected to the inner wall of the shell 1. A matching gear 271 is provided in the middle of the horizontal shaft 27, and a rack 262 that can mesh with the matching gear 271 is provided on both sides of the lifting seat 261. Two top sliders 272 are provided on the horizontal shaft 27, and two third circulation grooves in opposite directions are provided on the surface of the horizontal shaft 27.

A gasket 221 is rotatably provided on the top surface of the top turntable 22, and a top connecting rod 273 is rotatably provided between the top slider 272 and the gasket 221 (that is, one end of the top connecting rod 273 is rotatably connected to the top slider 272, and the other end of the top connecting rod 273 is rotatably connected to the gasket 221).

[0027] See also Figures 1 to 4 Preferably, the cleaning plate 232 can be a flexible scraper or a brush plate with bristles covered on the surface. The user can select a suitable cleaning plate 232 according to actual conditions.

[0028] See also Figures 1 to 4 Preferably, a plurality of horizontal bars 28 that can abut against the top turntable 22 are fixedly provided on the top of the shell 1, and the top surface of the top turntable 22 and the bottom surface of the horizontal bars 28 are both provided with rough surfaces, which can improve the positioning effect of the horizontal bars 28 on the top turntable 22.

[0029] See also Figures 1 to 4 Preferably, the driving member 211 is a rotating motor that can provide sufficient power.

[0030] During the implementation of the present invention, when it is necessary to clean the inner wall of the shell 1, the user starts the driving member 211, and the driving member 221 reverses. At this time, the positive ratchet does not cooperate with the positive pawl, the reverse ratchet cooperates with the reverse pawl, the driving gear 25 does not rotate, and the sleeve shaft 26 rotates, driving the lifting seat 261 to rise, thereby causing the two horizontal shafts 27 to rotate synchronously, and the two top sliders 272 on the same horizontal shaft 27 move away from each other, driving the top turntable 22 to rise. When the top turntable 22 is at the highest point of its motion range, the horizontal bar 28 abuts against the top turntable 22, and then the electromagnet applies a repulsive force to the sliding gear 24, the sliding gear 24 disengages from the locking groove, the driving gear 25 cooperates with the card slot, and then the driving member 211 rotates forward, and at this time the positive ratchet cooperates with the positive pawl , the anti-ratchet does not cooperate with the anti-ratchet pawl, the driving gear 25 rotates, the sleeve shaft 26 does not rotate, and the driving gear 25 drives the threaded tube 23 to rotate (the top turntable 22 does not rotate at this time), so that the two bottom sliders 231 move away from each other until the cleaning plate 232 abuts the inner wall of the shell 1, and then the electromagnet applies attraction to the sliding gear 24, the sliding gear 24 cooperates with the locking groove, the driving gear 25 disengages from the slot, and then the driving member 211 reverses, and the two top sliders 272 on the same horizontal shaft 27 approach each other, causing the top turntable 22 to descend. During this period, under the cooperation of the threaded tube 23 and the threaded shaft 212, several cleaning plates 232 rotate and descend at the same time, and the user can make the top turntable 22 reciprocate and rise and fall multiple times to ensure a good cleaning effect.

[0031] The utility model provides a degassing constant pressure water supply device, which has the following beneficial effects:

[0032] 1. By setting up the cleaning assembly, several cleaning plates can be folded together when idle to reduce the occupied space, and the cleaning plates can be made to abut against the inner wall of the shell when in use to ensure a good cleaning effect.

[0033] 2. By setting up a cleaning component, several cleaning plates can be rotated and lifted back and forth at the same time, thereby further improving the cleaning effect.

[0034] 3. This device only needs one driving part to operate, which reduces the cost of use.

[0035] In summary, the beneficial effects of the present invention are: it can not only ensure a good cleaning effect, but also reduce the space occupied by the cleaning plate when idle, and also reduce the cost of use.

[0036] Of course, the present invention may have many other embodiments.
