Abstract
Description
Technical Field
[0001] This invention relates to the field of fire-fighting water tank technology, specifically to a water quality and temperature control system and a fire-fighting water tank. Background Technology
[0002] Fire water tanks are man-made water storage facilities mainly used to store fire-fighting water, provide water source for fixed or mobile fire pumps, and ensure that the fire protection system has sufficient water volume and pressure to extinguish fires in the event of a fire. Fire water tanks are the core water storage facilities of building fire protection systems, and their design, installation and maintenance must strictly follow the specifications to ensure reliable water supply in the event of a fire.
[0003] Under standard conditions, in a 5-meter-deep pool, the water at that depth, like the surface water, begins to freeze at 0°C. However, freezing starts from the surface and requires sustained low temperatures for the ice layer to extend downwards. Furthermore, because cold water floats on top of warm water, the bottom temperature of a 5-meter-deep pool is likely to remain around 4°C for an extended period.
[0004] Obviously, when the temperature drops below zero in winter, the water in the fire water tank will freeze from the surface and gradually sink downwards, making the water in the fire water tank solid and unusable. In addition, when pumping water out of the fire water tank, the pump body sinks into the tank, which will disturb the silt at the bottom and make the water turbid, affecting the water quality of the fire water tank. Furthermore, aquatic plants will grow at the bottom of the tank, which may entangle or block the pump body, ultimately affecting water pumping. Therefore, a water quality and water temperature control system is needed to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide a water quality and temperature control system and a fire-fighting water tank to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A temperature control system, comprising a first temperature control system and a second temperature control system, wherein the first temperature control system comprises a temperature control box and a first thermal circuit connected to the temperature control box, and the second temperature control system comprises a central control box and a second thermal circuit connected to the central control box;
[0009] A conditioning system, comprising a water outlet circuit connecting the first thermal circuit and the second thermal circuit, and a gas circuit connected to the first thermal circuit and the second thermal circuit, wherein the gas circuit is used to position the first thermal circuit and the second thermal circuit at the water surface, so that the water outlet circuit draws water from the water surface, and the first thermal circuit and the second thermal circuit cooperate with the gas circuit to make the water temperature at the water surface higher than a set temperature.

The second inlet pipe is connected to the central control box through a second inlet hose. A second circulation pump connected to the second inlet hose is provided in the central control box.
[0014] Preferably, the water outlet circuit includes a return water connector connecting the first return water pipe and the second return water pipe, a drain pipe installed on the return water connector, an outlet pipe installed on the drain pipe, and a filter pipe installed on the outlet pipe. An electric valve two is installed on the return water connector, and an electric valve three is installed on the drain pipe.
[0015] Preferably, the heat pump is used to heat water and send it into the water storage tank, the first circulation pump is used to make hot water flow through the first inlet pipe, the connecting heat pipe, and the first return pipe back to the heat pump for heating, the connecting pump sends hot water into the central control box, and the second circulation pump is used to make hot water in the central control box flow through the second inlet pipe, the connecting heat pipe, the second return pipe, the return pipe, and the first return pipe back to the heat pump for heating.
[0016] Preferably, the gas circuit includes an air pump mounted on the central control box, a glass tube mounted on the central control box, a heating wire mounted inside the glass tube, an airbag mounted on the connecting heat pipe, an air pipe that connects the airbags in sequence, a pressure relief valve mounted at the end of the air pipe, and a one-way valve mounted on the air pipe.
[0017] Preferably, the air pump is used to pump the gas heated by the heating wire into the air bag.
[0018] On the other hand, a fire-fighting water tank is also provided, which includes the aforementioned water quality and temperature control system.
[0019] Compared with the prior art, the beneficial effects of the present invention are:
[0020] This invention reduces the flow distance of hot water by setting up a first temperature control system and a second temperature control system, preventing the hot water from becoming too cold at the end. By setting up a gas circuit, the outlet circuit and the temperature control system are always floating on the water surface, maintaining the heating of the water surface and pumping water from the water surface. Clean water is prioritized for pumping from the water surface, avoiding stirring up the silt at the bottom of the pool and reducing the possibility of aquatic plants getting tangled or blocking the filter pipe during pumping. This improves the water quality pumped from the filter pipe and prevents silt mixed in with the pumped water from damaging or blocking the water pump and pipeline circuit, affecting the quality of water spraying or fire extinguishing. The temperature control system heats the water surface to prevent the fire water pool from freezing. The outlet circuit setting facilitates water replenishment or replacement in the inner water storage tank while satisfying the water pumping function. Attached Figure Description

When it is necessary to replenish water to the inner water storage tank 4 or drain water that has been used for a long time in central control box 1 and inner water storage tank 4, electric valve 24 is opened and electric valve 10 and electric valve 23 are closed, so that circulation pump 9 can draw or discharge water through filter pipe 22.
[0038] The gas circuit includes an air pump 25, a glass tube 26, a heating wire 27, an air bag 28, an air pipe 29, a pressure relief valve 30, and a one-way valve 31.

The one-way valve 31 is located at the end where the air tube 29 connects to the glass tube 26. The air pump 25 is used to pump the gas heated by the heating wire 27 into the air bag 28. The water in the central control box 1 can absorb the heat in the glass tube 26 and reduce heat waste.
[0039] One end of the second water inlet pipe 14 is inserted between the second bracket 11 and the other end of the first water inlet pipe 6 is inserted between the first bracket 2, which restricts the floating of the first and second hot circuits and prevents them from floating randomly in the fire water tank 100.
[0040] A temperature sensor can also be installed on the heat pipe 16, and a controller, such as a microcontroller, can also be installed on the bracket 2. The temperature sensor, heat pump 5, circulation pump 9, electric valve 10, connecting pump 13, circulation pump 18, electric valve 23, electric valve 3 24, air pump 25, and heating wire 27 are respectively connected to the controller via data electrical signals.
[0041] When the water quality and temperature control system is installed in the fire water tank 100, the fire water tank 100 is equipped with an inlet pipe 120 for replenishing water to the fire water tank 100. An external pumping pipe 110 can be connected to the outlet pipe 21. A valve control switch can be installed at the end of the pumping pipe 110. The pumping pipe 110 can be a flexible hose.
[0042] Working principle: During use, air pump 25 starts, pumping the air heated by heating wire 27 into air bag 28. When the pressure inside air bag 28 reaches a certain value, pressure relief valve 30 opens to release the gas. Air pump 25 can be shut off at a timer, so that the temperature control system and conditioning system are both located at the water surface. When the temperature sensor detects that the water surface temperature has reached the set value, generally set to 1 degree, electric valve 10 and electric valve 23 open, and electric valve 3 24 closes. Heat pump 5 heats the water and sends it into the water storage tank 4. Circulation pump 19 makes the hot water flow through inlet pipe 6, connected to heat pipe 16, and return pipe 32 back to heat pump 5 for heating. Pump 13 is turned on to send the hot water into the central control box 1. Circulation pump 2 18 makes the central control box 1... Hot water in control box 1 flows through inlet pipe 14, connecting heat pipe 16, return pipe 15, return pipe 19, and return pipe 32 back to heat pump 5 for heating, so that the hot water in each pipe heats the water on the surface of fire water tank 100. When it is necessary to replenish water to the inner water storage tank 4 or to drain water that has been used for a long time in control box 1 and inner water storage tank 4, electric valve 3 24 is opened and electric valve 1 10 and electric valve 2 23 are closed, so that circulating pump 1 9 can draw or discharge water through filter pipe 22. When it is necessary to pump water out of fire water tank 100, electric valve 3 24 is closed and the external water pumping pipe 110 is connected to the flange on the outlet pipe 21, so that water at the water surface is always drawn through filter pipe 22.
