Description

Technical Field

[0001] The utility model relates to the technical field of groundwater recharging devices, in particular to a geothermal water recharging device. Background Art

[0002] Geothermal heating refers to a heating method that uses geothermal energy as the main heat source. This method can make full use of geothermal energy and has the advantages of saving energy and reducing heating costs. The heating process is to collect natural hot water underground as a heat source, and then extract the underground hot water and pump it into the heating pipes in the building. The heating pipes deliver the hot water to the indoor heating device, such as the radiator. The heat in the hot water is dissipated indoors through the heating device to achieve heating. The water after heating is completed is geothermal wastewater. In order to avoid thermal pollution and chemical pollution caused by direct discharge of geothermal wastewater, the return water in the heating pipe needs to be recharged into the recharge well.

[0003] For example, the application number is CN201922033438.0. The utility model provides a multi-stage pressurized geothermal water reinjection device, including a water storage tank, a pressure tank, a first booster pump and a second booster pump. The water outlet of the water storage tank and the water inlet of the pressure tank are connected through a connecting pipe. The drain port of the pressure tank is connected to one end of the reinjection pipe. The other end of the reinjection pipe passes through the well sealing device and extends into the reinjection well. The first booster pump is arranged on the connecting pipe, and the second booster pump is arranged on the reinjection pipe. The beneficial effect of the utility model is that the pressure tank of the reinjection device can store water pressurized by the first booster pump to maintain a certain water pressure, and the water is further pressurized by the second booster pump and then pressed into the reinjection well, so as to realize multi-stage pressurized reinjection of the reinjection water, and the power requirement of a single booster pump can be reduced; and the pressure tank makes the water in the reinjection pipe have a certain water pressure, which can prevent the water in the reinjection well from flowing back into the reinjection pipe due to the pressure in the well.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, although it can solve the problem that the water pressure in some recharge wells is high, the water pressure of the water pump output water is required to be higher than the water pressure in the recharge well when a water pump is used for direct pressurization, the cost of the high-pressure water pump is high, it is easy to damage, and when the water pump stops working due to a failure, it will cause the water in the recharge well to flow back into the recharge device, making the recharge work difficult. However, during use, the user needs to start multiple booster pumps for a long time to be able to recharge the water in the water storage tank into the interior of the recharge well, resulting in a large amount of electricity loss, and requires the coordinated use of multiple booster pumps, which increases the cost of use and the maintenance cost.

[0022] like Figures 1 to 3 As shown, the utility model provides a geothermal water reinjection device, including a base plate 1, a reflow well 2 and a water storage tank 3. The left side of the top of the base plate 1 is fixedly connected to the bottom of the reflow well 2, and the right side of the top of the base plate 1 is fixedly connected to a hydraulic rod 4. Two hydraulic rods 4 are provided, and the piston ends of the hydraulic rod 4 are fixedly connected to the two sides of the bottom of the water storage tank 3. A water pipe 5 is fixedly connected to the bottom of the left side of the water storage tank 3, and the water pipe 5 is connected to the water storage tank 3.

[0023] refer to Figure 2 and Figure 3 The air extraction mechanism 6 includes an air extraction pump 61, the bottom of the air extraction pump 61 is fixedly connected to the rear side of the top of the reflux well 2, the input end of the air extraction pump 61 is fixedly connected to an electromagnet 62, and an iron ring 63 is magnetically adsorbed on the front of the electromagnet 62.

[0024] As a technical optimization scheme of the utility model, by setting up the air suction mechanism 6, it is convenient for the user to start the air pump 61, so that the air pump 61 can extract the excess gas in the water pipe 5, and then the water pipe 5 will guide the water in the water tank 3 to the end of the water pipe 5 away from the water tank 3 under the action of air pressure, and then the user can turn off the electromagnet 62, so that the electromagnet 62 no longer adsorbs the iron ring 63, and then the water in the water tank 3 will be recharged into the reflux well 2.

[0025] refer to Figure 1 and Figure 3 The automatic control component 7 includes a control box 71, the bottom of which is fixedly connected to the front side of the top of the base plate 1, and the bottom of the input end of the air pump 61 is fixedly connected to a water immersion sensor 72, the top of the water immersion sensor 72 penetrates into the interior of the input end of the air pump 61, and the water immersion sensor 72 and the electromagnet 62 are electrically connected to the control box 71 through wires.

[0026] As a technical optimization scheme of the utility model, by setting up an automatic control component 7, when the water immersion sensor 72 on the input end of the air pump 61 detects water, the water immersion sensor 72 will send an electrical signal and control the electromagnet 62 and the air pump 61 through the control box 71, so that the electromagnet 62 and the air pump 61 are turned off, thereby facilitating automatic shutoff of the electromagnet 62 and the air pump 61.

[0027] refer to Figure 3 The surface of the electromagnet 62 is covered with a waterproof protective cover 8, and the material of the waterproof protective cover 8 is butyl rubber.

[0028] As a technical optimization scheme of the utility model, by setting a waterproof protective cover 8, the waterproof protective cover 8 can prevent the electromagnet 62 from being affected by water and causing the service life of the electromagnet 62 to be affected. The advantage of the good damping effect of butyl rubber is then utilized to prevent the electromagnet 62 from being damaged by excessive impact force generated when the electromagnet 62 and the iron ring 63 are adsorbed.

At the same time, the user can quickly replace the iron ring 63 when the iron ring 63 is damaged after long-term use.

After the water immersion sensor 72 on the end detects water, the water immersion sensor 72 will send out an electrical signal and control the electromagnet 62 and the air pump 61 through the control box 71, so that the electromagnet 62 and the air pump 61 are turned off, and then the electromagnet 62 will no longer be adsorbed on the iron ring 63, and then the end of the water pipe 5 away from the water storage tank 3 will move downward under the action of its own gravity, so that the end of the water pipe 5 away from the water storage tank 3 moves to the inside of the reflow well 2, so that the water in the water storage tank 3 is retained and recharged to the inside of the reflow well 2, which has the ability to save electricity and self-flow recharge.

[0036] To sum up: the geothermal water recharging device, by setting a hydraulic rod 4, starts the hydraulic rod 4, so that the hydraulic rod 4 drives the water storage tank 3 to move upward, so that a height difference is generated between the water storage tank 3 and the reflow well 2, and then uses siphon to move away, so that the water in the water storage tank 3 continues to flow to a lower position through the water pipe 5, and is recharged into the interior of the reflow well 2, which solves the problem that the user needs to start multiple booster pumps for a long time to recharge the water in the water storage tank into the interior of the recharge well, causing a large amount of electricity loss, and requires the coordinated use of multiple booster pumps, which increases the cost of use and the maintenance cost.
