Description

Technical Field

[0001] The invention belongs to the technical field of constant temperature heating for leisure pools, and in particular relates to a constant temperature system for unpowered leisure pools. Background Art

[0002] As the main leisure pool, hot spring bathing pools are mostly set up outdoors, and the peak season for hot spring bathing is mostly in autumn and winter. Due to the low outdoor temperature, in order to ensure the comfort of guests bathing, these outdoor hot spring bathing pools need to continuously replenish heat and raw water for the bathing pool water to ensure the comfortable water temperature of the bathing pool water. At present, the hot spring bathing pool heating usually adopts a circulating constant temperature method, that is, the water of the outdoor bathing pool is centrally pumped back, and a special heating circulation system is set up. The heat medium water is heated by a large gas boiler or electric boiler, and then the heat medium water and the cooled hot spring water pumped back from the bathing pool are exchanged through a heat exchanger, and finally the heated water is re-injected into the bathing pool. The main disadvantages are large equipment investment and high operating energy consumption.

[0003] In order to reduce operating costs, some small and medium-sized hot springs choose to use solar collectors to collect solar heat, converting the sun's light energy into thermal energy to heat the heat medium water. However, the daylight hours are short in winter and the sunlight is not strong enough to heat a large amount of heat medium water to the required temperature. Gas or electric heating is still needed for supplemental heating. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the existing hot spring pool solar energy heating cannot heat a large amount of heat medium water to the required temperature and still requires gas or electric heating for heating. A non-powered leisure pool constant temperature system is proposed. Based on the principle that hot water rises and cold water falls, an automatic heat collection mechanism is used to only guide the hot water on the upper layer of the upper heating tank to the lower heating tank for reheating. The water temperature can be quickly heated to the required temperature without the need for gas or electric heating for heating, with low energy consumption and low operating costs.

[0005] In order to solve the above technical problems, the present invention provides a non-powered leisure pool constant temperature system, comprising:

[0006] A bubble pool system, wherein the bubble pool system comprises a plurality of bubble pools, each bubble pool being provided with a water inlet and a water outlet, wherein the water inlet is connected to a water inlet branch pipe, which is connected to a water inlet main pipe, and the water outlet is connected to a drainage branch pipe, which is connected to a drainage main pipe;

[0007] A water return system, wherein the water return system comprises a water return pipe and a water return temporary storage tank, one end of the water return pipe is connected to the drainage main pipe, a water return circulation pump is arranged on the water return pipe, and the other end of the water return pipe is connected to the inlet of the water return temporary storage tank;

[0008] Purification system, the purification system comprises a water main pipe, a water purification device and a disinfection device, one end of the water main pipe is connected to the outlet of the return water temporary storage tank, and the other end is connected to the water purification device, a water pump and a check valve are arranged on the water main pipe, and the water purification device is connected to the disinfection device;

[0009] A heating and water replenishment system, the heating and water replenishment system comprises at least a primary heating tank, a secondary heating tank and a tertiary heating tank, the primary heating tank and the secondary heating tank are both provided with a built-in heat exchanger near the bottom, the heat exchanger is connected to the solar collector, the primary heating tank and the secondary heating tank, as well as the secondary heating tank and the tertiary heating tank are connected via an automatic heat collecting mechanism, the automatic heat collecting mechanism can export the upper layer of hot water in the primary heating tank to the secondary heating tank for reheating, or export the upper layer of hot water in the secondary heating tank to the tertiary heating tank, a drain outlet is provided at the bottom of the tertiary heating tank, the drain outlet is connected to a water replenishment outlet pipe, and the water replenishment outlet pipe is connected to the water inlet main pipe.

[0010] Furthermore, the automatic heat collection mechanism includes a guide pipe, a float, a float bracket and a water outlet pipe. The guide pipe is an L-shaped pipe consisting of a horizontal section and a vertical section. The horizontal section of the guide pipe is installed on the side wall of the heating tank through a bearing, and the vertical section of the guide pipe is located in the heating tank. The part of the horizontal section of the guide pipe located in the heating tank is fixed with a float bracket, and a float is installed on the top of the float bracket. The float bracket is parallel to the vertical section of the guide pipe, and the length of the float bracket is slightly larger than the length of the vertical section of the guide pipe. One end of the water outlet pipe is coaxially sleeved with the guide pipe, and the guide pipe and the water outlet pipe rotate relative to each other. When the water level in the heating tank is high, the float floats on the water surface, the float bracket is in a vertical state, the vertical section of the guide pipe is also in a vertical state, the inlet of the guide pipe is slightly lower than the water surface, the upper hot water can enter the outlet pipe through the guide pipe, and flow into the lower heating tank; as the water level drops, the float still needs to be loaded on the water surface, the float drives the float bracket to gradually tilt, the float bracket is fixed on the horizontal section of the guide pipe, thereby driving the horizontal section of the guide pipe to rotate slowly in the bearing, so that the vertical section of the guide pipe is also gradually tilted, the vertical inlet of the guide pipe is always slightly lower than the water surface, and the upper hot water continues to be guided out. When the water surface drops below the horizontal section of the guide pipe, the diversion stops, and the automatic heat collection mechanism of the present invention can automatically guide the upper hot water in the heating tank that is higher than the horizontal section of the guide pipe to the lower heating tank for continuous heating without power, and continue to heat up at the original temperature, so as to achieve the purpose of quickly raising the water temperature.

[0011] Furthermore, a coaxial shaft hole and a bearing hole are provided on the side wall of the heating tank. The bearing hole is located on the outer wall side of the heating tank, and the shaft hole is located on the inner wall side of the heating tank. The diameter of the bearing hole is larger than the diameter of the shaft hole. The bearing is installed in the bearing hole through a pressure ring and a locking nut. The horizontal section of the guide pipe passes through the shaft hole and is connected to the bearing. The connection between the guide pipe and the shaft hole and the sleeve connection with the water outlet pipe are sealed with sealing rings to prevent water leakage, which can not only make the guide pipe rotate smoothly but also prevent water leakage.

[0012] Furthermore, it also includes a central control system, which is electrically or communicatively connected to the bubble pool system, the water return system, the purification system and the heating and water replenishment system respectively.

[0013] Furthermore, the heating and water replenishment system further comprises a raw water replenishment pipeline, one end of which is connected to a raw water source, and the other end is respectively connected to a water inlet and / or a replenishment outlet pipe of the primary heating tank, and the raw water source comprises a tap water source and / or a hot spring raw water source. It is used to directly replenish raw water to the pool system, or to replenish the pool system with raw water after being heated by the heating and water replenishment system.

[0014] Furthermore, the return water pipe is also connected to a primary purification device, which is connected to a return water temporary storage tank, for performing preliminary filtering and purification on the return water before it enters the return water temporary storage tank, thereby reducing the cleaning frequency of the return water temporary storage tank.

[0015] Furthermore, the water purifier includes a first water purifier and a second water purifier, the inlet of the first water purifier is connected to the water main pipe through a first water delivery branch pipe, the inlet of the second water purifier is connected to the water main pipe through a second water delivery branch pipe, a first water delivery valve is provided on the first water delivery branch pipe, a second water delivery valve is provided on the second water delivery branch pipe, and the outlets of the first water purifier and the second water purifier are both connected to the disinfection device. The first water purifier and the second water purifier can be used alternately, or when one of the water purifiers fails or needs to replace the filter element and cannot be used, switch to the other water purifier for water purification.

[0016] The outlet of the first water purifier is also connected to the inlet of the second water purifier through a connecting pipe, a connecting pipe control valve is arranged on the connecting pipe, a water quality detector is arranged at the outlet of the first water purifier, and a control valve is arranged on the connecting pipe between the first water purifier and the disinfection device. When the water quality detector detects that the purified return water discharged from the outlet of the first water purifier does not meet the standards, the connecting pipe control valve on the connecting pipe can be opened to send the purified return water to the second purifier for further purification, so as to ensure that the purified return water discharged from the purification device meets the water quality standards.

[0017] Furthermore, the bubble pool is also provided with a bubble pool liquid level transmitter and a bubble pool temperature transmitter, which can monitor the liquid level and water temperature in the bubble pool in real time, and compare them with the set temperature and liquid level thresholds to determine whether it is necessary to open the water inlet control valve to replenish water and heat or open the drain control valve to drain water.

[0018] Furthermore, a mixed flow distributor is provided in the bubble pool, and the mixed flow distributor is connected to the water inlet of the bubble pool; the replenishing water entering the water inlet can be quickly dispersed and quickly mixed with the water in the bubble pool, avoiding excessive local temperature caused by sudden water inflow at the water inlet, thereby preventing scalding.

[0019] Furthermore, the three-stage heating tank is also equipped with a built-in heat exchanger near the bottom to further heat the water in the three-stage heating tank.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The water discharged from the hot spring pool system is purified and reused by using the return water system, purification system and heating and water replenishment system. When the water temperature of the hot spring pool drops, high-temperature hot water is added by using the heating and water replenishment system to increase the water temperature of the hot spring pool and improve comfort.

[0022] (2) The first-level heating tank is equipped with a built-in heat exchanger near the bottom. The heat exchanger is connected to the solar collector to transfer the heat radiated by the sun in the collector to the first-level heating tank in time, so as to heat the water in the first-level heating tank. The water at the bottom of the first-level heating tank absorbs heat first and heats up, and its specific gravity decreases. It continues to rise and is stored in the upper part of the first-level heating tank. At this time, the guide pipe of the automatic heat collection mechanism guides the upper hot water to the second-level heating tank, and only this part of the hot water is reheated, which can quickly increase the water temperature and make the water temperature reach the required temperature. Since a float bracket is fixed on the guide tube, and a float is connected to the float bracket, the float float disappears and floats on the liquid surface. As the liquid level drops, the float drives the float bracket to tilt, and drives the guide tube to rotate and tilt, so that the water inlet of the guide tube is always located a little below the liquid level, so that the upper layer of hot water always enters the secondary heating tank, and the upper layer of hot water in the primary heating tank enters the secondary heating tank for reheating, and the upper layer of hot water in the secondary heating tank is diverted into the tertiary heating tank (can continue to be heated) until the temperature reaches the preset value and is discharged into the bubble pool, so that only the upper layer of hot water is heated in stages, and the water temperature is quickly increased. Even in winter when the light is not strong, the water temperature can be raised to the required temperature;

[0023] (3) A central control system is set up to perform automatic control through the central control system to achieve precise control of the temperature in the bubble pool.

[0024] (4) The entire process does not require gas or electric heating for supplementary heating, has low energy consumption and low operating costs, and is suitable for all large, medium and small soaking pools. BRIEF DESCRIPTION OF THE DRAWINGS
