[0003] At present, the ground source heat pump unit has a problem of low vacuum degree in daily use, such as the problem caused by the vacuum pump temperature being too high or improper assembly. At this time, it is necessary to perform a vacuum operation. In addition, if the vacuum system of the unit leaks or other sealing parts need to be replaced, a nitrogen filling maintenance operation is required.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiments of the present application disclose a ground source heat pump unit maintenance and detection device.

[0034] Reference Figure 1 The ground source heat pump unit maintenance and inspection equipment includes a base 1, a fixed base 2 is fixedly connected to the top of the base 1, a push handle 3 is fixedly connected to one side of the base 1, a nitrogen tank 4 is installed inside the fixed base 2, a vacuum pump 5 is fixedly connected to the top of the fixed base 2, an air supply pipe 6 is fixedly connected to the output end of the nitrogen tank 4, an exhaust pipe 7 is fixedly connected to the output end of the vacuum pump 5, a three-way pipe 8 is fixedly connected to one side of the fixed base 2, one end of the air supply pipe 6 and the exhaust pipe 7 are fixedly connected to both sides of the three-way pipe 8, a connecting component 9 is installed at one end of the three-way pipe 8, a storage box 10 is installed on the top of the base 1, and a plurality of universal wheels 11 are symmetrically fixedly connected to the bottom of the base 1.

[0035] When in use, first push the push handle 3 to drive the base 1 to the side of the unit through the universal wheel 11, then take out the connecting component 9 from the storage box 10, quickly connect the two ends of the connecting component 9 to the unit pipeline and one end of the three-way pipe 8 respectively, and then start the nitrogen tank 4 and the vacuum pump 5 according to the situation of the unit. When the nitrogen tank 4 is running, the nitrogen inside the nitrogen tank 4 will be filled into the unit through the guidance of the gas pipe 6 to check whether there is a vacuum leak in the unit. When the inspection is completed, the nitrogen tank 4 can be closed and the vacuum pump 5 can be turned on. At this time, the inside of the unit can be vacuumed through the exhaust pipe 7. By connecting the connecting component 9 with the unit pipeline and the three-way pipe 8, the maintenance device does not need to disassemble and install the pipeline multiple times, and after the inspection and maintenance are completed, the connecting component 9 can be quickly and conveniently disassembled and separated, saving maintenance time and effectively improving the maintenance and inspection efficiency.

[0036] Reference Figure 3 and Figure 4 The connecting component 9 includes a fixed tube 91 fixedly connected to one end of the three-way tube 8, a mounting tube 92 is arranged inside one end of the fixed tube 91, a sliding block 93 is slidably connected to the fixed tube 91, and a sealing gasket 94 is fixedly connected to the inner walls of the fixed tube 91 and the mounting tube 92. A guide groove 95 is provided at one end of the fixed tube 91, a spring 96 is fixedly connected inside the guide groove 95, a fixed block 99 is fixedly connected to the inner wall of the sliding block 93, the fixed block 99 is slidably connected in the guide groove 95, one end of the spring 96 is fixedly connected to one side of the fixed block 99, a plurality of circular grooves are evenly provided in the guide groove 95, and a ball 97 is rotatably connected inside the plurality of circular grooves, the diameter of the ball 97 is larger than the diameter of the circular groove, a plurality of ball grooves 98 are evenly provided at one end of the mounting tube 92, and the shape and size of the plurality of ball grooves 98 are consistent with those of the ball 97

[0037] Secondly, a stopper 910 is fixedly connected to one end of the fixed tube 91 and the mounting tube 92, and a support column 911 is fixedly connected to the inside of the fixed tube 91 and the mounting tube 92. A sliding rod 912 is slidably connected to the inside of the support column 911, and a sealing ring 913 is fixedly connected to one end of the sliding rod 912. A spring 914 is sleeved on the sliding rod 912, and both ends of the spring 914 are fixedly connected to the support column 911 and one side of the sealing ring 913 respectively. A resistance block 915 is fixedly connected to one side of the sealing ring 913, and a sealing gasket 916 is fixedly connected to the outer wall of one end of the mounting tube 92. One end of the stopper 910 is inclined, and one side of the sealing ring 913 fits with the inclined surface of the stopper 910.

[0038] When in use, first insert one end of the three-way pipe 8 into the interior of the fixed pipe 91, and then insert the unit pipe into the interior of the mounting pipe 92. The two sealing gaskets 1 94 can maintain the sealing between the fixed pipe 91 and the three-way pipe 8, and between the mounting pipe 92 and the unit pipe, thereby reducing gas leakage. Then, push the sliding block 93 to drive the fixed block 99 to slide inside the guide groove 95, so that the fixed block 99 gradually moves away from the ball 97 to release the limit on the top of the ball 97, and squeeze the spring 1 96 to contract. At this time, insert one end of the mounting pipe 92 into the interior of the fixed pipe 91. After entering the interior of the fixed pipe 91, the sealing gasket 2 916 can improve the sealing between the fixed pipe 91 and the mounting pipe 92. The sealing property reduces gas leakage. When the installation tube 92 is completely inserted into the fixed tube 91, the sliding block 93 can be loosened. At this time, the spring 1 96 will push the sliding block 93 to drive the fixed block 99 to reset, so that the ball 97 is squeezed into the ball groove 98 through the bottom of the fixed block 99. The elasticity of the spring 1 96 will make the fixed block 99 always limit the ball 97 to prevent the ball 97 from separating from the ball groove 98. Therefore, the installation tube 92 can be completely clamped in the fixed tube 91 through the cooperation of the ball 97 and the ball groove 98, so as to realize the quick connection between the unit pipeline and the three-way pipe 8, effectively saving installation time and improving maintenance efficiency.

[0039] Secondly, after the installation tube 92 is connected to the unit pipeline, the elasticity of the second spring 914 will always push the sealing ring 913 to fit tightly with the inclined surface of the stop block 910. Through the cooperation between the stop block 910 and the sealing ring 913, the installation tube 92 can be in a sealed state after being connected to the unit pipeline, thereby avoiding leakage of gas and liquid inside the unit. Subsequently, when the installation tube 92 is installed and clamped with the fixed tube 91, the two resistance blocks 915 inside the fixed tube 91 and the installation tube 92 will resist each other. The resistance force generated by the two resistance blocks 915 will drive the two sealing rings 913 away from each other, so that the sealing ring 913 is separated from the inclined surface of the stop block 910, thereby releasing the sealing condition inside the fixed tube 91 and the installation tube 92. At the same time, through the elasticity of the two second springs 914, the two resistance blocks 915 can maintain mutual resistance to avoid affecting subsequent detection and maintenance, thereby greatly improving the overall practicality and convenience of the device.

[0040] Reference Figure 1 and Figure 2 A partition plate 101 is symmetrically fixedly connected inside the storage box 10.

[0041] When in use, the internal space of the storage box 10 can be divided by a plurality of partition plates 101, so that the detection and maintenance tools can be classified and stored more conveniently, making it easier to take the tools during the detection and maintenance process.

[0042] The implementation principle of the ground source heat pump unit maintenance and inspection equipment of this embodiment is as follows: when in use, first push the push handle 3 to drive the base 1 to the side of the unit through the universal wheel 11, then insert one end of the three-way pipe 8 into the interior of the fixed pipe 91, and then insert the unit pipe into the interior of the installation pipe 92. The two sealing gaskets 94 can maintain the sealing between the fixed pipe 91 and the three-way pipe 8 and the installation pipe 92 and the unit pipe to reduce gas leakage. Then push the sliding block 93 to drive the fixed block 99 to slide inside the guide groove 95, so that the fixed block 99 gradually moves away from the ball 97 to release the limit on the top of the ball 97, and squeeze the spring 96 to contract. At this time, insert one end of the installation pipe 92 into the interior of the fixed pipe 91. After entering the interior of the fixed pipe 91, through the sealing The second gasket 916 can improve the sealing between the fixed tube 91 and the installation tube 92 and reduce gas leakage. When the installation tube 92 is fully inserted into the fixed tube 91, the sliding block 93 can be loosened. At this time, the sliding block 93 can be pushed to drive the fixed block 99 to reset according to the rebound of the spring 1 96, so that the ball 97 is squeezed into the ball groove 98 through the bottom of the fixed block 99. The elasticity of the spring 1 96 will make the fixed block 99 always limit and intercept the ball 97 to prevent the ball 97 from separating from the ball groove 98. Therefore, the installation tube 92 can be completely clamped in the fixed tube 91 through the cooperation of the ball 97 and the ball groove 98, so as to realize the quick connection between the unit pipeline and the three-way pipe 8, effectively saving installation time and improving maintenance efficiency.

[0043] Secondly, after the installation tube 92 is connected to the unit pipeline, the elasticity of the second spring 914 will always push the sealing ring 913 to fit tightly with the inclined surface of the stopper 910. Through the cooperation between the stopper 910 and the sealing ring 913, the installation tube 92 can be in a sealed state after being connected to the unit pipeline, thereby preventing gas and liquid from leaking inside the unit. Subsequently, when the installation tube 92 is installed and clamped with the fixed tube 91, the two resistance blocks 915 inside the fixed tube 91 and the installation tube 92 will resist each other. The resistance force generated by the two resistance blocks 915 will drive the two sealing rings 913 to move away from each other, so that the sealing ring 913 and the inclined surface of the stopper 910 are separated, thereby releasing the sealing condition inside the fixed tube 91 and the installation tube 92. At the same time, through the elasticity of the two second springs 914, the two resistance blocks 915 can maintain mutual resistance to avoid affecting subsequent detection and maintenance, thereby greatly improving the overall practicality and convenience of the device.

[0044] Then, the nitrogen tank 4 and the vacuum pump 5 are started respectively according to the situation of the unit. When the nitrogen tank 4 is running, the nitrogen inside the nitrogen tank 4 will be filled into the unit through the guidance of the air pipe 6 to check whether there is a vacuum leak in the unit. When the inspection is completed, the nitrogen tank 4 can be closed and the vacuum pump 5 can be turned on. At this time, the inside of the unit can be vacuumed through the exhaust pipe 7. The quick connection between the unit pipeline and the three-way pipe 8 can make the maintenance device do not need to disassemble and install the pipeline multiple times, and after the inspection and maintenance is completed, the fixed pipe 91 and the installation pipe 92 can be quickly and conveniently disassembled and separated, saving maintenance time and effectively improving the maintenance inspection efficiency. The internal space of the storage box 10 can be divided by multiple partitions 101, so that it is more convenient to classify and store the inspection and maintenance tools, making it more convenient to take the tools during the inspection and maintenance process.
