A four-compartment solar cell that is frost-proof, deflated, and explosion-proof

Abstract

The present invention belongs to the technical field of solar water heaters, specifically a four-compartment solar energy heater that is anti-freezing, anti-deflation and explosion-proof, including an insulated water tank and an air intake pipe. A vacuum insulation pipe is installed on the left side above the body of the insulated water tank, and the inner cavity of the vacuum insulation pipe is connected with the inner cavity of the insulated water tank. The air intake pipe runs through the insulated water tank. The vacuum insulation pipe has the functions of anti-freezing and heat preservation, which can prevent the water inside the vacuum insulation pipe from freezing, and the inner cavity of the air intake pipe does not contact with water, so the air intake pipe will not be frozen and blocked. When the air pressure in the insulated water tank is lower than the external air pressure, the outside air can enter the insulated water tank, so that the air pressure in the insulated water tank is consistent with the external air pressure, thereby preventing the insulated water tank from being deflated by atmospheric pressure. When the air pressure in the insulated water tank is higher than the external air pressure, the gas in the insulated water tank can be discharged, thereby preventing the air pressure in the insulated water tank from being too high and causing the insulated water tank to explode.

Description

Technical Field

[0001] The invention relates to the technical field of solar water heaters, in particular to a four-compartment solar water heater that is anti-freezing, anti-deflation and explosion-proof. Background Art

[0002] my country has a vast territory and abundant solar energy resources, and solar energy is a renewable energy source. In modern times, solar energy is generally used to generate electricity or provide energy for water heaters. Solar water heaters convert sunlight energy into thermal energy and heat water from low temperature to high temperature to meet people's hot water needs in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structural form. Among them, vacuum tube solar water heaters are the main ones, and vacuum tube solar water heaters occupy 95% of the domestic market share. Vacuum tube household solar water heaters are composed of related parts such as heat collecting tubes, water storage tanks and brackets. The conversion of solar energy into thermal energy mainly depends on vacuum collecting tubes. Vacuum collecting tubes use the principle that hot water floats and cold water sinks to make water microcirculate and obtain the required hot water.

[0003] In cold weather, the water in the exhaust pipe of an existing solar water heater is prone to freezing, causing the exhaust pipe to be blocked. After the exhaust pipe is blocked, if the hot water in the solar water heater is used at this time, the air pressure in the insulated water tank of the solar water heater will be lower than the external atmospheric pressure, causing the insulated water tank of the solar water heater to be deflated by the atmospheric pressure. The blocked exhaust pipe will prevent the gas in the solar water heater from being discharged. When the water temperature in the solar water heater rises, the air pressure in the solar water heater will increase sharply, and the sharply increased air pressure will cause the insulated water tank of the solar water heater to explode.

The heat cabin is connected, and a normally open solenoid valve is installed below the insulation partition on the right side. The two sides of the normally open solenoid valve are respectively connected to the insulation cabin and the heating cabin through pipes. Water pressure sensors are installed at the bottom of the inner cavity of the water supply cabin and the heating cabin. A drain outlet is provided at the bottom of the inner cavity of the insulation cabin, and a No. 1 solenoid valve is provided below the body of the drain outlet. A heater is installed at the bottom of the inner cavity of the insulation cabin. A water supply pipe is connected above the water supply cabin, and the other end of the water supply pipe is connected to the filter cabin. A valve, a No. 2 solenoid valve and a water flow switch are provided on the body of the water supply pipe. A filter is provided in the inner cavity of the filter cabin, and the water flow switch is connected to the normally open solenoid valve through a wire. A central control chip is installed below the insulation water tank, and the No. 2 solenoid valve, No. 1 solenoid valve, a normally closed solenoid valve and two water pressure sensors are respectively connected to the central control chip through wires.

[0006] Preferably, the filter cabin comprises an upper cover and a lower cabin body, the upper cover is screwed onto the upper part of the lower cabin body, and the lower end of the upper cover is in contact with the filter screen.

[0007] Preferably, force holes are provided on both the left and right sides of the upper cover.

[0008] Preferably, a water outlet is provided above the upper cover, the water outlet is connected to a water supply pipe, and a water inlet is provided on the left side of the main body of the lower cabin.

[0009] Preferably, the bottom of the inner cavity of the lower cabin body is arranged in a V shape, and a sewage outlet is provided at the V-shaped bottom of the lower cabin body, and a lower cover is screwed below the sewage outlet.

[0010] Preferably, the vacuum insulation tube includes a vacuum tube and an insulation cover, and the insulation cover is screwed onto the top of the vacuum tube.

[0011] Preferably, a fixed block is sleeved on the outer side of the upper end of the air inlet pipe, and the outer side of the fixed block is in contact with the inner cavity wall of the vacuum insulation tube.

[0012] Preferably, the upper end of the drain outlet is connected to a drain pipe, the drain pipe is in the inner cavity of the heating chamber, a float is provided in the inner cavity of the heating chamber, a rope is connected below the float, and the other end of the rope is fixed to one end of the drain pipe.

[0013] Preferably, the heater and the normally open solenoid valve are connected via a wire, and the connection circuit between the heater and the normally open solenoid valve is a series circuit.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1) The vacuum insulation tube has the functions of antifreeze and heat preservation, which can prevent the moisture inside the vacuum insulation tube from freezing. The inner cavity of the air intake pipe does not come into contact with water, so the air intake pipe will not be frozen and blocked. When the air pressure in the insulated water tank is lower than the external air pressure, the external air can enter the vacuum insulation tube through the air intake pipe, and then enter the insulated water tank through the vacuum insulation tube, so that the air pressure in the insulated water tank is consistent with the external air pressure, thereby preventing the insulated water tank from being compressed by atmospheric pressure. When the air pressure in the insulated water tank is higher than the external air pressure, the gas in the insulated water tank is discharged through the vacuum insulation tube and the air intake pipe, thereby preventing the air pressure in the insulated water tank from being too high and causing the insulated water tank to explode.

[0016] 2) When the water in the solar water heater is not fully heated, the hot water in the insulated water tank is at the top and the cold water is at the bottom. The float drives the drain pipe to float, so that the drain pipe is always in the water above. When there is hot water from the solar energy, the hot water can be discharged from the drain pipe, avoiding the traditional solar water heater that requires the water in the tank to be fully heated before the hot water can be discharged;

[0017] 3) When the water temperature in the insulation chamber is not high enough, the heater can be turned on manually to heat the water in the insulation chamber. When the heater is working, the normally open solenoid valve is energized and closed, so that the water in the heating chamber and the insulation chamber cannot circulate, thereby reducing the heat loss in the insulation chamber.

[0026] Example:

[0027] See also Figure 1-4The present invention provides a technical solution: an anti-freeze, anti-deflation and explosion-proof four-compartment solar energy system, comprising an insulated water tank 1 and an air intake pipe 3. A vacuum insulation pipe 2 is installed on the left side above the body of the insulated water tank 1. The inner cavity of the vacuum insulation pipe 2 is connected to the inner cavity of the insulated water tank 1. The air intake pipe 3 runs through the insulated water tank 1. The upper end of the body of the air intake pipe 3 is in the inner cavity of the vacuum insulation pipe 2. The vacuum insulation pipe 2 has anti-freeze and heat preservation functions, and can provide anti-freeze protection for the air intake pipe 3 in severe cold weather. The inner cavity of the air intake pipe 3 does not come into contact with water, so the air intake pipe 3 will not be frozen and blocked. The air pressure in the insulated water tank 1 can be connected to the outside air pressure through the air intake pipe 3. The outer atmosphere is connected to the insulated water tank 1, thereby preventing the atmospheric pressure of the insulated water tank 1 from being too high or too low. If the atmospheric pressure of the insulated water tank 1 is too high, it will easily cause the insulated water tank 1 to explode. If the atmospheric pressure of the insulated water tank 1 is too low, it will easily cause the insulated water tank 1 to be compressed by the external atmospheric pressure. Insulation partitions 21 are provided on the left and right sides of the inner cavity of the insulated water tank 1. The two insulation partitions 21 divide the inner cavity of the insulated water tank 1 into three cabins. The cabin on the left side of the left insulation partition 21 is the water replenishment cabin, the cabin between the two insulation partitions 21 is the heating cabin, and the cabin on the right side of the right insulation partition 21 is the insulation cabin. The insulation partitions 21 on both sides are A water hole 22 is opened, a normally closed solenoid valve 20 is installed under the left insulation partition 21, and the two sides of the normally closed solenoid valve 20 are connected to the water supply cabin and the heating cabin through pipes, and a normally open solenoid valve 19 is installed under the right insulation partition 21. The two sides of the normally open solenoid valve 19 are connected to the insulation cabin and the heating cabin through pipes, and the bottom of the inner cavity of the water supply cabin and the heating cabin are installed with a water pressure sensor 17. A drain port 4 is provided at the bottom of the inner cavity of the insulation cabin, and a No. 1 solenoid valve 16 is provided below the body of the drain port 4. A heater 15 is installed at the bottom of the inner cavity of the insulation cabin. The top of the water supply cabin is connected to the There is a water supply pipe 5, the other end of the water supply pipe 5 is connected to the filter cabin 9, the filter cabin 9 is fixed to the external bracket by screws, the main body of the water supply pipe 5 is provided with a valve 6, a No. 2 solenoid valve 7 and a water flow switch 8, a filter screen 11 is provided in the inner cavity of the filter cabin 9, the water flow switch 8 is connected to the normally open solenoid valve 19 through a wire, a central control chip 18 is installed under the insulated water tank 1, the central control chip 18 is connected to the external power supply through a wire, the No. 2 solenoid valve 7, the No. 1 solenoid valve 16, the normally closed solenoid valve 20 and the two water pressure sensors 17 are respectively connected to the central control chip 18 through wires.

[0028] The filter cabin 9 includes an upper cover 91 and a lower cabin body 92 . The upper cover 91 is screwed onto the upper portion of the lower cabin body 92 , and the lower end of the upper cover 91 is in contact with the filter screen 11 .

[0029] Force holes 96 are provided on both the left and right sides of the upper cover 91 , and force rods can be inserted into the force holes 96 , thereby making it easier for cleaning personnel to open the upper cover 91 .

[0030] A water outlet 93 is provided above the upper cover 91, and the water outlet 93 is connected to the water filling pipe 5. A water inlet 94 is provided on the left side of the main body of the lower cabin 92. The water outlet 93 is provided at the top, which can facilitate the automatic falling of particulate impurities in the water under the action of gravity.

[0031] The bottom of the inner cavity of the lower cabin body 92 is set in a V shape. A sewage outlet 95 is opened at the V-shaped bottom of the lower cabin body 92. The lower cover 10 is screwed below the sewage outlet 95 to facilitate the discharge of sewage from the sewage outlet 95.

[0032] The vacuum insulation tube 2 includes a vacuum tube and an insulation cover, which is screwed onto the top of the vacuum tube. When the air intake pipe 3 is blocked by an accident, the insulation cover can be opened and then the air intake pipe 3 can be cleared from above with a stick.

[0033] A fixed block 12 is sleeved on the outer side of the upper end of the air intake pipe 3. The outer side of the fixed block 12 fits into the inner cavity wall of the vacuum insulation tube 2. There are support points at both ends of the air intake pipe 3, which can reduce the torque applied to the air intake pipe 3 and avoid bending of the air intake pipe 3 due to excessive torque.

[0034] The upper end of the drain outlet 4 is connected to a drain pipe 14, which is in the inner cavity of the heating chamber. A float 13 is provided in the inner cavity of the heating chamber. A rope is connected below the float 13, and the other end of the rope is fixed to one end of the drain pipe 14. When the water in the solar water heater is not fully heated, the hot water in the insulated water tank 1 is above and the cold water is below. The float 13 drives the drain pipe 14 to float, so that one end of the drain pipe 14 is always in the water area above, so that when there is hot water in the solar energy, the hot water can be discharged from the drain pipe 14, avoiding the need for the water in the traditional solar water heater to be fully heated before the hot water can be discharged.

[0035] The heater 15 and the normally open solenoid valve 19 are connected by a wire. The connection circuit between the heater 15 and the normally open solenoid valve 19 is a series circuit. After the heater 15 is turned on, the normally open solenoid valve 19 is powered on and closed, so that the water in the heating chamber and the insulation chamber cannot circulate, thereby reducing the heat loss in the insulation chamber.

[0036] Working principle: when adding water, water enters the filter cabin 9 from the water inlet 94, and then the water flows out from the water outlet 93 after being filtered through the filter screen 11. The water flowing out of the water outlet 93 flows into the water supply cabin through the water supply pipe 5. At the same time, when the water passes through the water flow switch 8, the normally open solenoid valve 19 will be powered on. The normally open solenoid valve 19 will be closed when powered on. The water entering the water supply cabin enters the heating cabin from the left water flow hole 22, and then the water in the heating cabin enters the insulation cabin through the right water flow hole 22. By closing the normally open solenoid valve 19, the time for cold water to enter the insulation cabin can be delayed, so that the insulation cabin can still release hot water when adding water. When the water in the heating cabin is completely filled, the water pressure sensor 17 in the heating cabin senses the pressure and transmits the signal to the central control chip 18. The central control chip 18 controls the No. 2 solenoid valve 7 to be powered on. After the No. 2 solenoid valve 7 is powered on, the air path is closed, so that the water in the filter cabin 9 cannot continue to be added to the insulation water tank 1;

[0037] After the water supply is cut off, when the water in the heating chamber and the insulation chamber is used up, the water pressure sensor 17 in the heating chamber senses the pressure and transmits the signal to the central control chip 18. The central control chip 18 receives the signal and controls the No. 1 solenoid valve 16 to close, so that the water in the insulation chamber cannot flow out. At the same time, the central control chip 18 controls the normally closed solenoid valve 20 to turn on the power, and the normally closed solenoid valve 20 opens. The water in the water supply chamber enters the heating chamber through the normally closed solenoid valve 20, and the water in the heating chamber enters the insulation chamber through the normally open solenoid valve 19, thereby preventing the solar water heater from running out due to lack of water. In the case of empty heating, when water comes from the outside, the water enters the water supply tank. When the water in the water supply tank is full, the water pressure sensor 17 in the water supply tank senses the pressure and transmits the signal to the central control chip 18. The central control chip 18 receives the signal and controls the No. 1 solenoid valve 16 to cut off the power supply. The No. 1 solenoid valve 16 connects the air path, allowing the water in the insulation chamber to continue to flow out. At the same time, the central control chip 18 controls the normally closed solenoid valve 20 to cut off the power supply. The normally closed solenoid valve 20 is disconnected from the air path, so that the water in the water supply tank can only enter the heating chamber again through the water flow hole 22 on the left;

[0038] When heating the water in the insulation chamber, the power supply of the heater 15 is turned on, and the normally open solenoid valve 19 is also turned on at the same time. The heater 15 heats the water in the insulation chamber. After the power supply of the normally open solenoid valve 19 is turned on, the air circuit of the normally open solenoid valve 19 is closed, thereby avoiding convection between the water in the insulation chamber and the water in the heating chamber, so that the heater 15 only needs to heat the water in the insulation chamber.
