[0002] In order to realize the goal of "carbon peak" and "carbon neutral", the use of new energy such as wind power and solar energy in industry and daily life is increasing. As a carrier of electric energy, energy storage can effectively smooth the volatility caused by large-scale new energy power generation connected to the power grid, promote the balance of power supply and load in power system operation, and improve the safety, economy and flexibility of power grid operation. Figure 1 In the energy storage cooling system, a pipeline connection method using pagoda joint is currently used: the flange at the front end of the pagoda joint extrudes the inner rubber layer of the hose, and the hose clamp fastens the hose in the smooth straight line segment area of the pagoda joint, and the hose is deformed under pressure and adheres to the surface of the metal joint. This pipeline connection method has the following defects:

[0003] 1) The smooth surface of the traditional pagoda joint in the clamp fastening area provides limited axial friction, and the anti-pullout effect is generally dependent on the flange structure at the front end of the joint, which is generally poor in anti-pullout effect and prone to slipping or even pullout.

[0004] 2) The traditional pagoda joint mainly relies on the flange structure at the front end to extrude the inner rubber layer of the hose to form a seal, and there is only one sealing point, which has a general sealing effect.

[0005] 3) The hose gradually ages over time, is affected by ultraviolet radiation, high temperature and humidity, etc., resulting in a decrease in the tensile strength and elasticity of the hose and a decrease in the sealing performance, and the traditional connection method cannot compensate for this, resulting in a shorter service life of the hose.

[0030] In the following, the utility model is further described in combination with the drawings and specific embodiments, and it needs to be explained that under the premise of not conflicting, the following described each embodiment or each technical feature can be combined to form a new embodiment.

[0031] Reference Figures 2-4 The utility model embodiment provides a novel pagoda hose joint for energy storage cooling system and pipeline connection structure adopting the novel pagoda hose joint 100.

[0032] Reference Figure 2 The novel pagoda hose joint 100 includes the tubular joint body 101, and the outer peripheral wall of the joint body 101 is provided with the annular limiting edge 102, the annular flange 103, the plurality of annular straight teeth 104 and the plurality of annular tooth grooves 105. The annular limiting edge 102 is between the front end and the rear end of the joint body 101, and the annular flange 103 is at the front end of the joint body 101. Wherein, the front end of the joint body 101 refers to the end for connecting the hose. The plurality of annular straight teeth 104 and the plurality of annular tooth grooves 105 are between the annular limiting edge 102 and the annular flange 103 and are alternately arranged along the axial direction of the joint body 101. Wherein, the annular flange 103 is higher than the annular straight tooth 104, and the annular limiting edge 102 is higher than the annular flange 103. The height contrast here is made with the radial direction of the joint body 101 as the height direction and with the inner peripheral wall of the joint body 101 as the reference surface. In addition, the tooth top 1041 of the plurality of annular straight teeth 104 is flush, and the bottom of the plurality of annular tooth grooves 105 is flush.

[0033] Preferably, in the novel pagoda-shaped hose joint 100 of the embodiment of the utility model, the tooth top 1041 of the annular straight tooth 104 and the tooth wall 1042 on both sides of the annular straight tooth 104 are connected through the arc curved surface 1043. The straight tooth profile is not easy to scratch the hose compared with the helical tooth profile, and in addition, the design of the arc curved surface 1043 can more effectively avoid scratching the hose, and improve the guarantee of the sealing performance and the connection firmness.

[0034] Reference Figure 3 And Figure 4 The pipeline connecting structure of the embodiment of the utility model, including novel pagoda-shaped hose joint 100, the hose of setting 200 and hose clamp 300. Among them, the front end of novel pagoda-shaped hose joint 100 is inserted into the hose of setting 200, and the front end of the hose of setting 200 is abutted to the annular limiting edge 102, the hose clamp 300 is sleeved on the outside of the hose of setting 200, and the position of the hose clamp 300 corresponds to the area where the plurality of annular straight teeth 104 and the plurality of annular tooth grooves 105 are located.

[0035] The advantages of the embodiment of the utility model are as follows:

[0036] 1) The area of novel pagoda-shaped hose joint 100 that is fastened by the hose clamp 300 is the continuous annular straight tooth 104, the hose of setting 200 will be extruded and then tightly attached to the right-angle tooth top 1041, and will also stretch to the annular tooth groove 105, thereby enhancing the axial friction, reinforcing the combination of the hose and the joint, and effectively avoiding slipping, pulling out and other situations.

[0037] 2) The hose of setting 200 will be hardened, brittle, and have reduced elasticity due to aging caused by time and environment, which will affect the sealing effect, but due to the structural characteristics of the annular straight tooth 104, the part of the hose of setting 200 that contacts the tooth top 1041 of the annular straight tooth 104 will age first, but the part of the hose that stretches to the annular tooth groove 105 has not aged and still maintains sufficient softness and elasticity, and the contact with the tooth wall 1042 can achieve sufficient compression rate, thereby ensuring the sealing property; this connecting structure reasonably plays the performance of the hose, which is conducive to prolonging the service life of the hose.

[0038] 3) The design of the plurality of annular straight teeth 104 and the annular tooth grooves 105 can provide multiple sealing points, as the installation time increases, the hose of setting 200 naturally vulcanizes to form multiple teeth, these teeth cooperate with the straight teeth of the joint to form a labyrinth-type seal, and a small amount of leaked liquid can only slowly flow out through the tiny gap between the teeth; combined with the viscosity of the medium itself, the leaked liquid generates a friction effect in the labyrinth-type flow channel, which hinders the outflow of the liquid, thereby enhancing the sealing property.

[0039] 4) The traditional connection mode of the cone joint can cause slippage and disengagement under 4bar air pressure / water pressure, while the novel cone hose joint can ensure the sealing and disengagement resistance of the hose under air pressure / water pressure of 4bar or above, and meets the working conditions of the energy storage system.

[0040] The above-mentioned embodiments are only preferred embodiments of the utility model, and cannot be used to limit the range of the utility model protection, and any non-substantial change and replacement made by the person skilled in the art on the basis of the utility model belongs to the range of the utility model protection.
