Description

Technical Field

[0001] The invention relates to the field of pool water level control, and in particular to an automatic pool water level compensation device. Background Art

[0002] There are many places where water pools are used in industrial production. Some water pools used in production need to have a certain pressure range and have requirements for water pressure. The water pressure of the water pool is reflected in the water level. Under the same area, when the water level is high, the water pressure is high, and when the water level is low, the water pressure is low. The size of the water pressure can be achieved by controlling the water level.

[0003] The water-seal check valve is also called a float valve. Its function is to require that the inlet pressure must be higher than the design pressure to allow the medium to pass through, and to ensure that the medium at the outlet will not flow back into the inlet pipe when the inlet pressure is low. In the prior art, the water-seal check valve is generally used as a safety valve for automatic water level monitoring, gas pressure protection, etc.

[0004] The water-seal check valve in the prior art is generally used for pressure relief. That is, after the water level in the sink and pool reaches a certain height, the water-seal check valve is driven by water pressure to expose the pressure relief pipe sealed by the water-seal check valve. However, it cannot be used to replenish water autonomously when the pressure is reduced, and cannot replenish water when the water pressure is insufficient, and manual judgment and replenishment are required.

[0023] An automatic pool water level compensation device is shown, which includes a columnar shell 1 fixed at the drain outlet of the pool and a water pressure equalizing component 2 slidably engaged in the shell 1 and movable along the axial direction of the shell. When the water pressure in the pool is greater than a preset value, the water pressure equalizing component 2 can float the water pressure equalizing component 2, so that the water pressure equalizing component 2 slides upward relative to the shell 1, so that the water in the pool passes through the automatic compensation device and enters the check valve to discharge the water.

[0024] A water inlet is provided on the side wall of the shell 1, and the water inlet connects the interior of the shell 1 with the outside, and can be a through structure of any suitable shape, such as a round hole, a square hole, a long slot, etc. In the present embodiment, the water inlet is a double wave-shaped water-adaptive pattern 3.

[0025] The water pressure equalizing component 2 includes a floating section 201 arranged in the upper section of the shell 1, a water volume regulating section 202 arranged in the middle section of the shell 1, and a water pressure response float 203 arranged in the lower section of the shell. The floating section 201 adjusts the buoyancy of the water pressure equalizing component 2 in the water pool. When the water level slowly covers the floating section 201, the buoyancy of the water on the entire water pressure equalizing component 2 slowly increases until the water level overflows the uppermost end of the floating section 201, and the buoyancy remains unchanged. The required water level can be set at any position corresponding to the height of the floating section 201.

[0026] The water volume regulating section 202 regulates the flow rate of water in the pool entering the water in the housing 1, thereby adjusting the drainage rate, so that water replenishment and drainage will not be frequent due to excessive drainage rate, and drainage time will not be too long due to low drainage rate.

[0027] The cooperation between the water pressure response float 203 and the shell 1 realizes the opening and closing of the pool drain. When the water level is higher than the set value, the water pressure equalization component 2 moves up along the shell 1 as a whole, and the water pressure response float 203 leaves the end of the shell 1, so that the pool is connected to the drain, forming an unobstructed waterway to discharge excess water in the pool.

[0028] The floating section 201 includes a sleeve 2014 slidably connected to the inner side of the upper end of the shell 1, and the sleeve 2014 and the end of the shell 1 limit the sleeve 2014 through a limit ring to prevent the sleeve 2014 from sliding out of the shell 1; the upper end of the sleeve 2014 is threadedly connected to a floating cavity 2011 with a hollow structure, and the lower end of the sleeve 2014 is threadedly connected to a position adjustment column 2012 with a solid structure. The distance and overall length between the sleeve 2014, the floating cavity 2011 and the position adjustment column 2012 are adjusted by adjusting the threaded structure among the sleeve 2014, the floating cavity 2011 and the position adjustment column 2012 to adjust the volume of the floating section 201 exposed in the water, thereby adjusting the buoyancy of the water on the floating section 201, and finally used to adjust the water level.

[0029] The thread structures among the sliding sleeve 2014, the floating chamber 2011 and the advance adjustment column 2012 all adopt a sealed thread structure to prevent water from entering the interior of the floating section 201 and affecting the calculation of buoyancy.

[0030] A bottom edge of the floating chamber 2011 is threadedly connected to the outer surface of the sliding sleeve 2014 and is sleeved on the outer side of the sliding sleeve 2014. The advance adjustment column 2012 is threadedly connected to the inner surface of the sliding sleeve 2014 and is embedded in the inner surface of the sliding sleeve 2014.

[0031] The top of the floating chamber 2011 should be higher than or equal to the required water level. The higher the water level, the greater the buoyancy of the floating chamber 2011. When the preset water level is reached, the buoyancy drives the water pressure equalizing assembly 2 to move upward as a whole, opening the passage for drainage.

[0032] An air pressure balance hole 2013 is provided in the middle of the top edge of the floating chamber 2011 away from the sliding sleeve 2014. An airtight bolt is installed in the air pressure balance hole 2013. When adjusting the volume of the floating section 201, the airtight bolt is opened for adjustment.

[0033] The water volume regulating section 202 includes a water inlet cylinder 2021 whose inner surface is provided with an internal thread structure which is integrated with the advance regulating column 2012. A drainage column 2022 is provided inside the water inlet cylinder 2021. One end of the drainage column 2022 is an integrated structure with the advance regulating column 2012, connecting the water volume regulating section 202 and the floating section into a whole.

[0034] The upper end of the water pressure responsive float 203 is provided with a plurality of connecting rods 2023 evenly distributed along the same circle, and the radial outer surface of the connecting rod 2023 is provided with an external thread matching the water inlet cylinder 2021, and the connecting rod 2023 is threadedly connected to the inside of the water inlet cylinder 2021, connecting the water pressure responsive float 203 and the water volume regulating section 202 into a whole. Here, the connecting rod 2023 can also adopt a tubular structure, and an external thread is provided on its outer surface, which is connected to the internal thread of the water inlet cylinder 2021, and can also produce the same effect. The use of the connecting rod 2023 structure can increase the contact area between the lower surface of the floating section 201 and the water, thereby enhancing the buoyancy effect.

[0035] The gap between the drainage column 2022 and the water inlet cylinder 2021 is greater than the thickness of the connecting rod 2023 , and the connecting rod 2023 can be screwed into the water inlet cylinder 2021 .

[0036] The water pressure responsive float 203 and the lower end of the housing 1 are provided with a one-way limit, and when the water pressure responsive float 203 moves downward, it cannot completely separate from the end surface of the housing 1, so that the water pressure responsive float 203 and the end surface of the housing 1 are in a closed state.

[0037] The outer sleeve of the water inlet cylinder 2021 is provided with a limit block 6, and the outer shell 1 is provided with a limit groove 7 at a position corresponding to the water inlet cylinder 2021. The limit block 6 is stuck in the limit groove 7 to limit the radial movement of the water inlet cylinder and prevent the water pressure equalization component arranged inside from shaking.

[0038] A spring 2024 is arranged on the outside of the connecting rod 2023, one end of the spring 2024 is fixed on the upper surface of the water pressure response float 203, and the other end is fixed on the limit block 6. The spring 2024 is in a stretched state and exerts an upward pulling force on the float.

[0039] A reset mechanism is provided at the lower part of the water pressure response float 203, and the reset mechanism includes a circular bottom plate parallel to the lower surface of the water pressure response float 203 and a reset connection block connecting the bottom plate with the lower end surface of the shell 1, one end of the reset connection block is fixed on the bottom plate, and the other end is fixed on the end surface of the shell 1, a guide rod is provided in the middle of the lower surface of the water pressure response float 203, and a reset spring in a stretched state is sleeved on the guide rod, one end of the reset spring is fixed to the lower surface of the water pressure response float 203, and the other end is fixed to the surface of the bottom plate, and the guide rod passes through the middle of the bottom plate for positioning.

[0040] The elastic potential energy of the restoring spring in the stretched state is greater than the elastic potential energy of the spring 2024 in the stretched state, so that the water pressure response float 203 is in a downward moving state in the absence of water.

[0041] The water pressure response float 203 is provided with a water replenishment switch harness, which controls the water replenishment switch by sensing the pressure change of the water pressure response float 203. When the water replenishment switch harness senses that the water pressure response float 203 has produced a downward displacement, a signal is given to control the water replenishment switch to open and replenish the water in the pool. When the water is replenished to a certain extent, the water replenishment switch harness senses that the water pressure response float 203 has produced an upward displacement, and a signal is given to control the water replenishment switch to close.

[0042] When the present invention is used, the housing 1 is fixed at the drain outlet upstream of the check valve of the pool, the water pressure response float 203 is placed in the drain outlet, and the distances among the sliding sleeve 2014, the floating chamber 2011 and the carry-in adjustment column 2012 are adjusted to appropriate positions to determine the water level. At this time, the water in the pool enters the housing 1 from the water-adaptive pattern 3. When the water level is not high enough, the buoyancy generated by the water on the float section 201 is less than the resultant force exerted on the water pressure response float 203, and the water pressure response float 203 moves downward. At this time, the water replenishment switch harness gives a signal to control the water replenishment switch to open, and water is replenished into the pool. When the water level is higher than the preset water level, When the water flows downward, the buoyancy of the floating section 201 is greater than the resultant force exerted on the water pressure response float 203. The buoyancy will drive the entire water pressure equalization assembly 2 to slide upward relative to the outer shell 1. At this time, the water pressure response float 203 is not in contact with the end face of the outer shell 1, so that water enters the drain port through the hole on the lower end face of the outer shell 1 and is discharged. During the drainage process, the buoyancy of the water on the floating section 201 gradually decreases. When the water level reaches the preset water level, the buoyancy of the water on the floating section 201 is equal to the resultant force exerted on the water pressure response float 203. At this time, the water pressure response float 203 is just stuck at the end face of the outer shell 1, closing the waterway. At this time, it is in a balanced state, with no drainage or water replenishment.

[0043] The present invention adjusts the change in the acting force between the buoyancy change and the spring elastic force to achieve automatic drainage when the water pressure in the pool is high and automatic water replenishment when the water pressure is low, thereby facilitating the control of the pool pressure, automating the pool pressure control and reducing labor input.
