[0018] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0019] The present invention provides the following embodiments: Example 1

[0020] The embodiment of the present invention provides a novel distributed heating network heating system, such as Figure 1As shown, it includes a heating end 1, which adopts a boiler for heating. The heating end 1 is connected to a heating pipeline 2, which is connected to a plurality of heating branches 10 and a heating pipeline 2 6, which is connected to a stable heating device 7, which is connected to a heating end 2 4. The heating end 2 4 adopts solar energy and geothermal energy for heating. The stable heating device 7 is used to keep the heat provided by solar energy stable. A plurality of heating branches 10 are connected to a plurality of heat dissipation ends 8 in a one-to-one correspondence, and a plurality of heat dissipation ends 8 are connected to a plurality of recovery branches 9 in a one-to-one correspondence. A plurality of recovery branches 9 are connected to a recovery pipeline 3, and the recovery pipeline 3 is respectively connected to the heating end 1 and the stable heating device 7.

[0021] The beneficial effects of the above technical solution are: When heating is performed, the setting of the heating end 1 heats water through a boiler, and the setting of the heating end 2 4 heats water through solar heating and geothermal heating. The heated water flows into the heating pipe 2 6 through the heating pipe 2, and the hot water in the heating pipe 2 flows to the heat dissipation end 8 through the heating branch pipe 10 to dissipate heat at the heat dissipation end 8. After the hot water dissipates heat, it flows back into the heating end 1 and the heating end 2 4 through the recovery branch pipe 9 and the recovery pipe 3, is reheated and flows into the heating pipe 2, and circulates in this way, thereby achieving the purpose of heating. A control valve can be respectively set at the hot water outlet of the heating end 1 and the hot water outlet of the heating end 2 4, and a control valve provided at the heating end 2 4 When the heat is sufficient, the control valve of the hot water outlet of the heating end 1 can be closed. When the heat provided by the heating end 2 4 is insufficient, the control valves corresponding to the hot water outlets of the heating end 1 and the heating end 2 4 can be opened, so that the heating end 2 4 and the heating end 1 can provide heat at the same time. By using two clean energy sources, solar energy and geothermal energy, for heating, the environmental pollution caused by using the heating end 1 for heating is reduced, energy is saved, and geothermal energy can still be used for heating in the winter when there is a lack of solar energy, so as to solve the technical problems that the above-mentioned distributed heat network heating system only discloses the use of solar energy for heating, and when the solar energy is insufficient, a heat unit needs to be used for heating, and the clean energy used is single and has poor applicability. The stable heating device 7 is used to keep the heat provided by solar energy to the heat dissipation end stable, avoid frequent fluctuations in solar energy leading to frequent system adjustments, reduce the operating stability of the system, and solve the problem that solar energy is easily fluctuated with changes in the outdoor environment. In the hybrid heating mode of the above-mentioned new distributed thermal network heating system, since solar energy is already in a insufficient condition, if the solar energy fluctuates, it is easy to affect the heating effect on the heat dissipation end. If the heating effect on the heat dissipation end is to be guaranteed, the system must be adjusted according to the fluctuations in solar energy. Frequent fluctuations in solar energy will lead to frequent system adjustments, which is easy to affect the technical problem in the stable operation of the system. Example 2

[0022] On the basis of Example 1, Figure 1 As shown, the outlet of the heating end 1 is connected with the inlet 1 of the heating pipeline 2, and the several outlets 1 of the heating pipeline 2 are connected with the inlets of the several heating branch pipes 10 in a one-to-one correspondence, the inlet 2 of the heating pipeline 2 is connected with the outlet of the heating pipeline 2 6, and the inlet of the heating pipeline 2 6 is connected with the outlet of the stable heating device 7, and the outlets of the several heating branch pipes 10 are connected with the inlets of the several heat dissipation ends 8 in a one-to-one correspondence, and the outlets of the several heat dissipation ends 8 are connected with the inlets of the several recovery branch pipes 9 in a one-to-one correspondence, and the outlets of the several recovery branch pipes 9 are connected with the several inlets of the recovery pipeline 3 in a one-to-one correspondence, and the two outlets of the recovery pipeline 3 are connected with the inlet of the heating end 1 and the inlet of the stable heating device 7 respectively; A temperature detector 5 is installed on one side of the plurality of heating branch pipes 10 close to the heat dissipation end 8, for detecting the temperature of the hot water in the heating branch pipe 10; Regulating valves are installed on the heating pipeline 1 2 , a plurality of heating branch pipes 10 , the heating pipeline 2 6 , a plurality of recovery branch pipes 9 and the recovery pipeline 3 .

[0023] The beneficial effects of the above technical solution are: The heating end 1 is a coal-fired boiler, and the heating end 2 4 includes a solar heater and a geothermal pump. When the heating end 2 4 and the heating end 1 are providing heat at the same time, the coal-fired boiler exchanges heat with water to provide hot water. The solar heater includes a solar collector and an air-water heat exchanger. The hot air in the solar collector enters the air-water heat exchanger, and the heat-released water in the recovery pipeline 3 enters the air-water heat exchanger to exchange heat with the hot air to complete the heating of the water. The geothermal pump refers to CN201820828904-a geothermal pump, which transfers the heat of the groundwater to the heat-released water in the recovery pipeline 3 to achieve the purpose of heating the water in the recovery pipeline 3, and The temperature of groundwater does not change much throughout the year, and does not fluctuate too much with changes in the outdoor environment like solar energy, which makes geothermal heating stable and reliable. The temperature detector 5 is set to detect the temperature of hot water flowing into the heat dissipation end 8, so as to obtain the heat dissipated by the hot water at the heat dissipation end 8. Regulating valves are installed on the heating pipeline 1 2, several heating branch pipes 10, heating pipeline 2 6, several recovery branch pipes 9 and recovery pipeline 3. By changing the opening of the regulating valve, the flow rate of water in the heating branch pipe 10, heating pipeline 2 6, several recovery branch pipes 9 and recovery pipeline 3 can be adjusted, thereby adjusting the heat dissipated by the hot water at the heat dissipation end 8. Example 3

[0024] On the basis of Example 2, Figure 1-Figure 7As shown, the stable heat supply device 7 includes a heat supply tank, which includes a cylinder 701. The cylinder covers 702 are symmetrically provided on the front and rear sides of the cylinder 701. The front and rear ends of the cylinder 701 are penetrated with working chambers 736. The right side of the lower end of the cylinder 701 is provided with a heat supply pipe 3 737 and a discharge pipe. The upper end of the cylinder 701 is provided with a liquid inlet shell 704. The interior of the liquid inlet shell 704 is provided with a liquid inlet cavity 735. The upper end of the liquid inlet shell 704 is provided with a liquid inlet pipe 707. The liquid inlet pipe 707 is connected to the recovery pipeline 3. The lower end of the liquid inlet shell 704 is provided with a liquid outlet pipe 738. The liquid inlet pipe 707 is connected to the liquid outlet pipe 738 through the liquid inlet cavity 735. The liquid outlet pipe 738 penetrates the right side of the upper end of the cylinder 701 and is connected to the working chamber 736. The working chamber 736 is connected to the heat supply pipeline 2 6 through the heat supply pipe 3 737. A heat exchange shell 705 is installed at the left end of the cylinder 701. Two heat dissipation coils 706 are arranged inside the heat exchange shell 705. The two heat dissipation coils 706 are connected to the solar heater and the geothermal pump respectively. A heat exchange pipeline 740 is also arranged inside the heat exchange shell 705. The inlet of the heat exchange pipeline 740 is connected to the recovery pipeline 3. A valve three is installed at the inlet of the heat exchange pipeline 740. The outlet of the heat exchange pipeline 740 is connected to the heating pipeline 2 6.

[0025] The beneficial effects of the above technical solution are: The two heat dissipation coils 706 are respectively connected to the solar heater and the geothermal heat pump, so that heat medium flows in the two heat dissipation coils 706. An on-off valve 2 can be set at the connection between the heat dissipation coil 706 and the solar heater, and an on-off valve 1 can be set at the connection between the heat dissipation coil 706 and the geothermal heat pump. By closing the on-off valve 1 and opening the on-off valve 2, the heating end 2 4 only uses solar energy for heating, which is suitable for the situation where solar energy is sufficient. By opening the on-off valve 1 and closing the on-off valve 2, the heating end 2 4 only uses geothermal energy for heating, which is suitable for the situation where there is no solar energy. When the on-off valve 1 and the on-off valve 2 are both opened, the heating end 2 4 uses solar energy and geothermal energy for heating, which is suitable for the situation where solar energy is insufficient. The cylinder 701 is made of a material with good heat exchange effect. When the heat provided by the heating end 2 4 is sufficient, the control valve at the outlet of the heating end 1 is closed, and the valve 3 is opened to allow the water in the recovery pipeline 3 to flow into the heat exchange pipeline 740. The heat medium in the heat dissipation coil 706 exchanges heat with the water in the heat exchange pipeline 740. The heated water enters the heating pipeline 1 2 through the heating pipeline 2 6 to dissipate heat at the heat dissipation end 8. If the heat provided by the heating end 2 4 is insufficient and needs to be heated together with the heating end 1, the valve 3 is closed and the liquid inlet pipe 707 is opened to allow the water in the recovery pipeline 3 to flow into the liquid inlet pipe 707 through the liquid inlet pipe 707. The water in the liquid inlet chamber 735 flows into the working chamber 736 through the liquid outlet pipe 738, and the heat medium in the heat dissipation coil 706 exchanges heat with the water in the working chamber 736 until the water in the working chamber 736 reaches the target temperature. Then, the heating pipe 3 737 is opened, and the water enters the heating pipe 1 2 through the heating pipe 3 737 and the heating pipe 2 6. In this process, the water in the working chamber 736 plays a heat storage role until it is heated to the target temperature so that it can carry heat and merge with the hot water provided by the heating end 1. Before merging with the hot water provided by the heating end 1, the heating end 2 4 does not provide heat. At this time, only the heating end 2 4 provides heat. The heat provided by the heating end 1 is regulated to be kept constant to ensure the target heating effect for the heat dissipation end 8. After the water in the working chamber 736 is heated to the target temperature, the heat it carries is combined with the hot water provided by the heating end 1. Since the heat provided by the heating end 24 is also kept constant, and the temperature of the hot water provided by the heating end 24 is greater than or equal to the temperature of the hot water provided by the heating end 1, the heating end 1 can be regulated at this time to reduce the heat provided by the heating end 1 while ensuring the target heating effect for the heat dissipation end 8, thereby saving the energy consumed in the heating process of the heating end 1. After the heated water in 36 flows out, it flows back into the liquid inlet chamber 735 through the liquid inlet pipe 707 to replenish water and heat it, and the amount of heat provided by the heating end 1 is readjusted. The setting of the above-mentioned stable heating device 7 achieves the purpose of heating through the heating end 2 4, and also makes it only necessary to adjust the amount of heat provided by the heating end 1 when the target temperature hot water provided by the heating end 2 4 merges with the hot water provided by the heating end 1, thereby avoiding the hot water in the heating pipeline 2 being affected by the fluctuation of solar energy, and the temperature of the hot water provided by it fluctuates frequently, thereby frequently adjusting the amount of heat provided by the heating end 1 and the heating end 2 4. Example 4

The rope winding drum 714 is wound on A pull rope 715 is wound around it, and the pull rope 715 is fixedly connected to the counterweight block 716. A contact plate 710 is correspondingly provided on the lower side of the counterweight block 716. The contact plate 710 is fixedly connected to the rear cylinder cover 702. The positioning block 711 contacts the guide block 712 correspondingly. The guide block 712 is slidably connected to the groove, and a spring is fixedly provided between the guide block 712 and the groove. The groove is arranged inside the driving sleeve 709, and the groove is communicated with the opening groove 713. The opening groove 713 is arranged at one end of the driving sleeve 709 close to the cylinder body 701. The end of the driving sleeve 709 away from the cylinder body 701 is fixedly connected to the motor 708. The motor 708 is fixedly connected to the rear cylinder cover 702 through the support block. The liquid pushing plate 721 is a heat insulating plate, and a movable opening is provided in the middle of the liquid pushing plate 721, and a pushing block 722 is slidably provided in the movable opening. A matching block 1 723 is provided at the front end of the pushing block 722. The inclined section on the right side of the matching block 1 723 is slidably connected with the inclined section of the matching block 2 728. The matching block 2 728 is fixedly connected with the connecting block 1 729. The connecting block 1 729 passes through the rotating disk 2 724 and is fixedly connected with the sliding sleeve 732. Through holes are provided at the front and rear ends of the sliding sleeve 732, and the through holes cooperate with the fixed shaft 730. The fixed shaft 730 is fixedly connected with the cylinder cover 702 on the front side. An arc groove 731 is provided on 730, and the arc groove 731 is slidably matched with the guide ball. The guide ball is installed in the through hole. The end of the sliding sleeve 732 away from the connecting block 1 729 is fixedly connected to the connecting block 2 739. The connecting block 2 739 passes through the front cylinder cover 702 and is fixedly connected to the connecting block 3 727. The connecting block 3 727 is fixedly connected to the connecting block 4 717. The connecting block 4 717 is fixedly connected to the connecting block 5 733. The connecting block 5 733 passes through the front end of the liquid inlet shell 704, enters the liquid inlet cavity 735, and is fixedly connected to the stopper 734. The stopper 734 is used to block the liquid inlet pipe 707.

[0027] The beneficial effects of the above technical solution are: The liquid pushing plate 721 is in a vertical state in the initial state. The arrangement of the rotating disk 1 720, the rotating disk 2 724 and the cylinder 701 makes the working chamber 736 a closed space. The liquid pushing plate 721 divides the working chamber 736 into two independent closed spaces on the left and right. The liquid pushing plate 721 is made of heat-insulating material. The heat exchange shell 705 is arranged at the left end of the cylinder 701. When the water in the recovery pipeline 3 flows into the working chamber 736, it is heated in the left space of the working chamber 736. After the water in the working chamber 736 is heated to the target temperature, the temperature of the left space of the working chamber 736 will also increase. At the same time, due to the increase in water temperature, the density of water decreases, but the volume of the left space of the working chamber 736 remains unchanged, so the pressure in the left space of the working chamber 736 increases. The cleaning liquid is arranged in the right space of the working chamber 736. Since the liquid pushing plate 721 is made of heat-insulating material, the temperature of the cleaning liquid remains unchanged. At this time, the heated water will push the pushing block 722 to move to the right along the movable opening. When the pushing block 722 moves to the right, it drives the matching block 1 723 to move. The matching block 1 723 drives the matching block 2 728 to move forward. The matching block 2 728 drives the connecting block 1 729 to move forward. The connecting block 1 729 drives the sliding sleeve 732 to move forward. Since the fixed shaft 730 is fixedly arranged on the cylinder cover 702 on the front side, the guide ball on the sliding sleeve 732 slides forward along the arc groove 731. The sliding sleeve 732 passes through the connecting block 2 739, the connecting block 3 727, the connecting block 4 717 and the connecting block The fifth 733 drives the block 734 to move forward, and the block 734 no longer blocks the liquid inlet pipe 707, and the liquid inlet pipe 707 gradually opens. During this process, the sliding sleeve 732 also rotates, and the sliding sleeve 732 drives the rotating disk 2 724 to rotate through the connecting block 1 729, and the rotating disk 2 724 drives the rotating disk 1 720 to rotate through the liquid pushing plate 721. The rotating disk 1 720 drives the rope drum 714 to rotate through the driving shaft 718, and the pull rope 715 wound on the rope drum 714 rotates in the direction of loosening, and the counterweight block 716 moves downward. During this process, the driving shaft 718 drives the positioning block 711 to contact the inclined end of the guide block 712, pushing the guide block 712 into the groove, and the spring is compressed, so that the connection with the motor 708 The driving sleeve 709 does not rotate until the rotating disk 2 724 rotates 180 degrees. At this time, the guide ball cannot slide forward along the arc groove 731, and the rotating disk 2 724 and the rotating disk 1 720 stop rotating. The counterweight block 716 just falls on the contact plate 710. At this time, the heated water also rotates 180 degrees along with the liquid pushing plate 721, and rotates from the left space of the working chamber 736 to the right space. At this time, the liquid inlet pipe 707 is fully opened to add the water to be heated to the liquid inlet chamber 735, and the spatial volume of the liquid inlet chamber 735 is equal to the left space of the working chamber 736 and equal to the right space of the working chamber 736. At the same time, the heating pipe 3 737 is opened, so that the heated water flows out through the heating pipe 3 737 for heating; A little space is left on the right side of the working chamber 736 after the cleaning liquid is put in, so that the pushing block 722 can move freely along the movable opening, and the remaining space after the cleaning liquid is put in should not be too large, so that the weight volume of the cleaning liquid in the right side of the working chamber 736 and the weight volume of the water in the left side of the working chamber 736 should be consistent, to ensure that the force required for the rotation process of the push plate 721 remains stable, and the target temperature for heating the water in the working chamber 736 is set to be greater than the hot water temperature provided by the heating end 1. Even if there is an error in the weight volume of the cleaning liquid in the right side of the working chamber 736 and the weight volume of the water in the left side of the working chamber 736 due to the influence of the environment and temperature changes, it can still be ensured that the target temperature for heating the water in the working chamber 736 is greater than the hot water temperature provided by the heating end 1 After that, the push plate 721 can be driven to rotate, that is, the force required for the rotation of the push plate 721 is provided by the gravity of the counterweight block 716 and the pressure difference between the left and right spaces of the working chamber 736, that is, after the water in the left space of the working chamber 736 is heated to the target temperature, the push block 722 begins to move freely along the movable port, the push block 722 is made of heat-insulating material, and the push block 722 is sealed with the movable port, and the push plate 721 can start to rotate, and the friction between the push block 722 and the movable port, the friction between the guide ball and the arc groove 731, and the friction between the connecting block 1 729 and the rotating disk 2 724 are negligible. The setting of the counterweight block 716 is used to assist in driving the push plate 721 to rotate. Since the force required for the rotation of the push plate 721 remains unchanged, By changing the weight of the counterweight block 716, the pressure difference between the left and right spaces of the working chamber 736 can be adjusted, thereby changing the target temperature of the water to be heated in the left space of the working chamber 736. After the water heated in the working chamber 736 flows out, the liquid outlet pipe 738 opens, so that the water to be heated in the liquid inlet chamber 735 flows to the right space of the working chamber 736, leaving a certain space, and then the motor 708 is controlled to work, the motor 708 drives the drive sleeve 709 to rotate, the drive sleeve 709 drives the guide block 712 to rotate, the horizontal section of the guide block 712 contacts the positioning block 711, and the guide block 712 does not enter the groove at this time, thereby driving the drive shaft 718 to rotate 180 degrees in the opposite direction, and the drive shaft 718 drives the rotating disk 1 720 and the rope drum 714 to rotate in the opposite direction. The first rotating disk 720 drives the second rotating disk 724 to rotate 180 degrees in the opposite direction through the liquid pushing plate 721. In this process, the water to be heated is transferred to the left space of the working chamber 736 for heating. When the second rotating disk 724 rotates, the sliding sleeve 732 is driven to rotate in the opposite direction through the connecting block 1 729, so that the guide ball on the sliding sleeve 732 slides backward along the arc groove 731. The sliding sleeve 732 drives the connecting block 1 729 and the connecting block 2 739 to move backward. The connecting block 1 729 drives the matching block 2 728 and the matching block 1 723 to return to their original positions. The connecting block 2 739 drives the stopper 734 to re-block the liquid inlet pipe 707.The liquid inlet chamber 735 is no longer replenished with water to be heated, and finally the push block 722 is restored to its original position, and the water to be heated flows to the right side of the working chamber 736, and the space left enables the push block 722 to move freely along the movable opening; The automatic liquid replacement mechanism is set up, and when the heat storage requirement is met, the water to be heated to the target temperature can be replaced with new water to be heated, and the rotation of the liquid pushing plate 721 utilizes the pressure difference between the enclosed space where the heated water is located and the enclosed space where the unheated cleaning liquid is located. The overall temperature of the heated water is required to reach the target value, which is beneficial to ensure the temperature uniformity of the heated water. Even if there is a temperature gradient in the heated water, the liquid pushing plate 721 can mix the heated water during the rotation process. If a temperature sensor is used to detect the temperature of the heated water, the temperature sensor controls the switch of the liquid outlet pipe 738 after the water temperature reaches the target temperature. It is easy for the water temperature in the temperature sensor detection area to reach the target value, while the water temperature in the remaining areas does not reach the target value, which ultimately affects the heating effect of the heating end 2 4. Example 5

[0028] On the basis of Example 4, Figure 1-Figure 7 As shown, a gear 726 is provided on the left and right sides of one end of the rotating disk 2 724 away from the liquid pushing plate 721, and the gear 726 is meshed with the gear ring 725. The gear ring 725 is fixedly arranged on the inner wall of the cylinder cover 702 on the front side. The gear 726 is fixedly connected to the connecting shaft 719. The connecting shaft 719 passes through the rotating disk 2 724 and is fixedly connected to the cleaning roller. The connecting shaft 719 is fixedly connected to the rotating disk 1 720.

[0029] The beneficial effects of the above technical solution are: When the rotating disk 724 rotates, the gears 726 on the left and right sides are driven to revolve. When the gears 726 rotate along the gear ring 725, they can rotate on their own. In this process, the gears 726 drive the cleaning roller to rotate through the connecting shaft 719. Figure 1-Figure 7 The cleaning roller is not shown. The cleaning roller is arranged between the rotating disk 2 724 and the rotating disk 1 720, and the cleaning roller contacts the side wall of the working chamber 736. The rotation of the cleaning roller cleans the impurities attached to the side wall of the working chamber 736 to prevent the working chamber 736 from being attached with impurities in the water after long-term use, which affects the heat exchange effect of the cylinder 701. The cleaning liquid can be mixed with the impurities scraped off by the cleaning roller when the liquid pushing plate 721 rotates. The discharge pipe is used to discharge the cleaning liquid carrying impurities, and new cleaning liquid can be replaced through the liquid outlet pipe 738. Example 6

[0030] On the basis of Example 4, Figure 1-Figure 7As shown, valve 2 is installed on the liquid outlet pipe 738, valve 1 is installed on the heating pipe 3 737, a liquid level sensor is provided on the right side of the working chamber 736, a weighing sensor is provided on the contact plate 710, the weighing sensor is electrically connected to valve 1 through controller 1, and the liquid level sensor is electrically connected to valve 1, valve 2 and motor 708 respectively through controller 2.

[0031] The beneficial effects of the above technical solution are: After the weighing sensor detects the weight of the counterweight 716, it indicates that the counterweight 716 falls on the contact plate 710. At this time, the weighing sensor controls valve one to open through controller one, so that the heating pipe three 737 discharges the heated water. After the liquid level sensor detects that the water level has dropped to the target water level, that is, after the heated water has been discharged, the liquid level sensor controls valve one to close and valve two to open through controller two. At this time, the water to be heated in the liquid inlet chamber 735 flows into the working chamber 736 through the liquid outlet pipe 738 until the liquid level sensor detects that the water level has risen to the target water level. The liquid level sensor controls valve two to close through controller two, and controls the motor 708 to start working, driving the drive sleeve 709 to rotate 180 degrees, thereby realizing the purpose of automatically discharging the heated water and replenishing the water to be heated, without manual operation, saving time and effort.

[0032] The temperature detector 5, valve 1, valve 2, weighing sensor, liquid level sensor, controller 1 and controller 2 of the present invention all adopt existing equipment, and the transmission technology between the above-mentioned electrical components all adopts existing technology, which will not be repeated in the present invention.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
