Description

Technical Field

[0001] This utility model relates to the technical field of ground source heat pump water distribution equipment, and in particular to a diversion device for gas-liquid circulation of ground source heat pumps. Background Technology

[0002] Ground source heat pumps are a new type of air conditioning system. They are relatively novel because they rely on geothermal energy to operate. Ground source heat pumps use geothermal energy as a heat source and cold source. In the hot summer, they absorb heat from the indoor air and transfer it to the soil, which then becomes geothermal energy. Similarly, in the cold winter, they transfer the heat contained in the soil to the indoor environment, thereby raising the indoor temperature.

[0003] Because the gas-liquid circulation diversion device of the ground source heat pump needs to draw groundwater during use, and the groundwater is usually not purified, the mud and other impurities mixed in the groundwater will adhere to the inner wall of the pipe. Over time, the impurities accumulate and form a large amount of scale. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a diversion device for gas-liquid circulation of ground source heat pump, so as to solve the technical problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A flow divider for vapor-liquid circulation in a ground source heat pump includes:

[0007] The support rod is fixedly connected to a water collection pipe and a water distribution pipe at both ends. A fitting pipe is rotatably installed at one end of the water collection pipe and the water distribution pipe. A spiral scraper is installed inside the fitting pipe. A sealing cap is rotatably installed at the other end of the fitting pipe. A drain valve is installed at the bottom of the sealing cap.

[0008] The end of the water collection pipe and the water distribution pipe away from the fitting pipe is equipped with a connecting bracket. Both ends of the connecting bracket are equipped with a communicating vessel, which is connected to the water collection pipe and the water distribution pipe respectively. The other end of the communicating vessel is connected to the water supply pipe. Several water outlet components are provided on the side walls of the water collection pipe and the water distribution pipe.

[0009] Furthermore, the inner diameter of the bonding pipe is larger than the inner diameter of the water distribution pipe and the water collection pipe, so that a sunken part is formed at the connection between the bonding pipe and the water distribution pipe.

[0010] Furthermore, a water channel is provided at the center of the spiral scraper, and a fiber layer is provided on the outer peripheral wall of the spiral scraper.

[0011] Furthermore, the outer peripheral wall of the closed cover is fitted with a positioning sleeve, and a connecting rod is provided between the two positioning sleeves. The connecting rod and the mounting support rod are fixedly connected by an extension rod.

[0012] Furthermore, a ratchet assembly is provided between the sealing cover and the positioning sleeve for positioning the rotation angle of the sealing cover.

[0013] Furthermore, the water outlet assembly includes:

[0014] The discharge pipe is connected to the water collection pipe. An isolation baffle is fixedly installed inside the discharge pipe. The side of the isolation baffle facing the water collection pipe is arc-shaped and smoothly transitions with the inner wall of the water collection pipe.

[0015] In summary, this utility model has at least one of the following beneficial technical effects:

[0016] 1. A diversion device for gas-liquid circulation in a ground source heat pump, wherein when water flows into the inside of the water collection pipe and the water distribution pipe, the water flow will drive the spiral scraper to move, so that the fiber layer set on the outer periphery of the spiral scraper scrapes the inner wall of the water collection and water distribution pipe, thereby cleaning the pipe and preventing the accumulation of scale and stains. In addition, during the scraping process, the spiral scraper will push the dirt into the inside of the pipe and deposit it, avoiding the dirt from remaining in the pipe and affecting the flow efficiency;

[0017] 2. This type of gas-liquid circulation diversion device for ground source heat pumps, when dirt is deposited inside the bonding pipe, rotate the sealing cover so that the drain valve is located at the bottom, and at this time the bent pipe is vertically downward to facilitate the discharge of dirt. On the other hand, when venting air from inside the pipe, rotate the sealing cover so that the drain valve is located at the top, at this time the discharge end of the bent pipe is vertically upward and the pipe opening is located above the bonding pipe, so that air can be discharged from the bent pipe to achieve the purpose of gas-liquid separation.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example:

[0026] Reference Figures 1-4 The present invention discloses a diversion device for vapor-liquid circulation in a ground source heat pump, comprising:

[0027] The support rod 1 is fixedly connected to a water collection pipe 2 and a water distribution pipe 3 at its two ends. A fitting pipe 4 is rotatably installed at one end of each water collection pipe 2 and water distribution pipe 3. A spiral scraper 5 is installed inside the fitting pipe 4. When water flows into the water collection pipe 2 and water distribution pipe 3, the water flow pushes the spiral scraper 5 to move, causing the fiber layer 14 on the outer periphery of the spiral scraper 5 to scrape the inner walls of the water collection pipe 2 and water distribution pipe 3, thus cleaning the pipes and preventing the accumulation of scale and stains. During the scraping process, the spiral scraper 5 pushes dirt into the fitting pipe 4 for deposition. A sealing cap 6 is rotatably installed at the other end of each fitting pipe 4. A drain valve 7 is installed at the bottom of the sealing cap 6. Figure 4 As shown, the end of the drain valve 7 can be connected to a bent tube. When dirt is deposited inside the fitting tube 4, the sealing cover 6 is rotated so that the drain valve 7 is located at the bottom, and the bent tube is vertically downward at this time, so as to facilitate the purpose of draining dirt. On the other hand, when draining the air inside the fitting tube 111, the sealing cover 6 is rotated so that the drain valve 7 is located at the top, and the discharge end of the bent tube is vertically upward at this time, and the tube opening is located above the fitting tube 4. At this time, the air can be discharged from the bent tube to achieve the purpose of gas-liquid separation.

[0028] A connecting bracket 8 is provided at the end of the water collection pipe 2 and the water distribution pipe 3 away from the fitting pipe 4. A communicating vessel 9 is provided at both ends of the connecting bracket 8. The communicating vessels 9 at both ends are connected to the water collection pipe 2 and the water distribution pipe 3 respectively. The other end of the communicating vessel 9 is connected to the water supply pipe 10. Several water outlet components 11 are provided on the side walls of the water collection pipe 2 and the water distribution pipe 3. The water outlet components 11 are used to install indoor water pipes so that the water distribution pipe 3 and the water collection pipe 2 can form a loop and pass the medium into different pipes. The connecting bracket 8 and the communicating vessel 9 are used to connect the water supply pipe 10 to provide medium water to the water distribution pipe 3 and the water collection pipe 2.

[0029] In this embodiment, when water flows into the water collection pipe 2 and the water distribution pipe 3, it drives the internal spiral scraper 5 to rotate. The fiber layer 14 on its outer periphery scrapes the inner wall of the pipe in real time to prevent the accumulation of scale and dirt. The dirt is collected and deposited in a directional manner. The spiral scraper 5 pushes the peeled dirt into the fitting pipe 4 connected to the rotating pipe for concentrated deposition, avoiding the retention of dirt in the pipe and affecting the flow efficiency.

[0030] Furthermore, the sealing cap 6 at the end of the fitting tube 4 is rotatable, and connects to the bent tube via the bottom drain valve 7 to achieve two functions:

[0031] Sewage discharge mode: Rotate the sealing cover 6 to lower the drain valve 7, and the deposited sewage will be discharged through the bend pipe. Figure 4 As shown;

[0032] Exhaust mode: Rotate the closed cover 6 to make the drain valve 7 move upward, and the bend in the pipe moves vertically upward, so that the air in the pipe can be discharged, thus achieving gas-liquid separation.

[0033] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the inner diameter of the bonding pipe 4 is larger than the inner diameter of the water distribution pipe 3 and the water collection pipe 2, so that a sunken part 12 is formed at the connection between the bonding pipe 4 and the water distribution pipe 3.

[0034] In this embodiment, a recessed portion 12 is formed by the difference in inner diameter between the fitting pipe 4, the water distribution pipe 3, and the water collection pipe 2, such as... Figure 2 As shown, the sinking part 12 can effectively settle dirt and prevent dirt from flowing back into the water distribution pipe 3 or the water collection pipe 2.

[0035] In a further preferred embodiment of this utility model, such as Figure 4 As shown, a water channel 13 is provided at the center of the spiral scraper 5, and a fiber layer 14 is provided on the outer peripheral wall of the spiral scraper 5.

[0036] In this embodiment, the water channel 13 prevents the spiral scraper 5 from excessively affecting the water flow, and the fiber layer 14 improves the cleaning ability of the spiral scraper 5 on the water collection pipe 2 and the water distribution pipe 3.

[0037] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the outer peripheral wall of the closed cover 6 is fitted with a positioning sleeve 15, and a connecting rod 16 is provided between the two positioning sleeves 15. The connecting rod 16 is fixedly connected to the mounting support rod 1 through an extension rod 17.

[0038] In this embodiment, the extension rod 17 and the connecting rod 16 are used to fix the positioning sleeve 15, and the positioning sleeve 15 is used to improve the stability of the rotation of the closed cover 6.

[0039] In a further preferred embodiment of this utility model, such as Figure 1 As shown, a ratchet assembly is provided between the sealing cover 6 and the positioning sleeve 15 to position the rotation angle of the sealing cover 6.

[0040] In this embodiment, the ratchet assembly is used to limit the rotation angle of the sealing cover 6, so that the sealing cover 6 can stop at any angle, thereby achieving the purpose of adjusting the position of the drain valve 7.

[0041] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the water outlet assembly 11 includes:

[0042] The discharge pipe 111 is connected to the water collection pipe 2. An isolation baffle 112 is fixedly installed inside the discharge pipe 111. The side of the isolation baffle 112 facing the water collection pipe 2 is arc-shaped and smoothly transitions with the inner wall of the water collection pipe 2.

[0043] In this embodiment, multiple water outlet components 11 on the side walls of the water collection pipe 2 and the water distribution pipe 3 are connected to the indoor water pipe to form a closed loop, ensuring that the medium water circulates in the heating / cooling system. The isolation baffle 112 is a mesh structure used to filter impurities in the water, and its arc-shaped end can fit with the spiral scraper 5 to remove impurities from the surface of the isolation baffle 112.

[0044] The implementation principle of the above embodiment is as follows: the water flow drives the spiral scraper 5 with fiber layer 14 to rotate, continuously scraping off the scale on the inner wall of the water collection pipe 2 / water distribution pipe 3, and the dirt is guided to the larger inner diameter fitting pipe 4 for deposition; the rotatable sealing cover 6, together with the ratchet assembly, realizes dual-mode switching - in the sewage discharge mode, the deposits are discharged through the bottom drain valve 7, and in the exhaust mode, the bent pipe faces upward to realize gas-liquid separation.

[0045] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
