[0026] The specific implementation methods of the utility model are described below to facilitate technical personnel in this technical field to understand the utility model, but it should be clear that the utility model is not limited to the scope of the specific implementation methods. For ordinary technical personnel in this technical field, as long as various changes are within the spirit and scope of the utility model defined and determined by the attached claims, these changes are obvious, and all utility model creations using the concept of the utility model are protected.

[0027] like Figure 1 , 2As shown in , 3 and 4, the tubular bus monitoring device is used in conjunction with the tubular bus. The tubular bus monitoring device includes an upper shell 1 and a lower shell 2 of the same structure. The upper shell 1 and the lower shell 2 are connected to form a columnar accommodating chamber 1. After the upper shell 1 and the lower shell 2 are connected, the shell is covered on the outside of the first tubular bus 6 and the second tubular bus 7 to protect the connection of the tubular bus. A monitoring device 5 is arranged in the accommodating chamber 1. The monitoring device 5 is electrically connected to the current sensor and the temperature sensor on the tubular bus. The monitoring device 5 is connected to the current sensor and the temperature sensor arranged in the first tubular bus 6 and the second tubular bus 7 through a signal line 14. Among them, the monitoring device 5 in this embodiment only needs to realize the monitoring function, which can be realized by a variety of existing feasible implementation methods. For example, a controller is used to control the connection of the current sensor and the temperature sensor, which is a common technology known in the art, so it is not specifically limited here. An alarm light or a speaker can also be arranged on the outer wall of the upper shell 1, and the alarm light or the speaker can be used to conveniently and timely discover abnormal conditions. A channel for installing the signal line 14 is reserved at the circumferential edge of the tubular busbar connecting section. Specifically, a circumferential outward convex strip is pressed out of the tubular busbar connecting section, so that after the tubular busbar connecting section is connected to the connecting rod 8, an axial channel for accommodating the signal line 14 is formed.

[0028] The left and right sides of the upper shell 1 are both provided with a sealing groove 12 and a water-absorbing cotton groove 13. The sealing groove 12 is provided at the outer side of the end of the upper shell 1. A sealing rubber member 4 is provided in the sealing groove 12. The water-absorbing cotton groove 13 is provided with a water-absorbing cotton ring 3. The water-absorbing cotton ring 3 is made of sponge material. The water-absorbing cotton ring 3 is used to absorb rainwater entering the shell and prevent rainwater from further flowing into the shell. A mounting ring 44 for mounting the sealing rubber member 4 is provided on the tubular busbar. The mounting ring 44 is made of plastic material or rubber material. The mounting ring 44 is sealed and connected to the busbar pipeline. The sealing rubber member 4 is used to fix and install the sealing rubber member 4.

[0029] like Figure 5As shown, the sealing rubber member 4 includes an inner rubber ring 41, an outer rubber ring 42 and a connecting ring surface 43. The inner rubber ring 41 and the outer rubber ring 42 are connected by the connecting ring surface 43. The inner rubber ring 41, the outer rubber ring 42 and the connecting ring surface 43 are designed as one body, and the connecting ring surface 43 is in the shape of a film. The outer rubber ring 42 is fixed on the upper shell 1, and the inner rubber ring 41 is fixed on the mounting ring 44. The outer portion of the mounting ring 44 is provided with an outer annular groove that matches the inner rubber ring 41, and the cross section of the outer annular groove is semicircular. The upper shell 1 is provided with an inner annular groove that matches the inner rubber ring 41, and the cross section of the inner annular groove is semicircular. The inner rubber ring 41 is bonded to the outer annular groove of the mounting ring 44, the outer rubber ring 42 is bonded to the outer annular groove on the upper shell 1, and the sealing rubber member 4 is connected between the shell and the tubular busbar. Since the connecting annular surface 43 has a certain elastic range, when the tubular busbar vibrates, the vibration of the tubular busbar will not be transmitted to the shell, so that the monitoring device 5 on the shell will not be affected by the vibration. The monitoring effect of the monitoring device 5 can also be guaranteed under the action of strong winds or earthquakes.

[0030] The outer diameter of the water-absorbing cotton ring 3 is excessively or interference-fitted with the water-absorbing cotton groove 13, and the water-absorbing cotton ring 3 is excessively or interference-fitted with the tubular busbar. When the sealing rubber part 4 is damaged, the sealing effect is weakened, and rainwater will enter the shell. The water-absorbing cotton ring 3 can effectively absorb rainwater and block rainwater from entering the housing cavity of the shell to prevent the monitoring device 5 from getting wet. The cross-sections of the water-absorbing cotton groove 13 and the water-absorbing cotton ring 3 are rectangular, the water-absorbing cotton ring 3 has a certain thickness, and has a larger contact area with the shell and the tubular busbar, so that the water-absorbing and water-blocking effects of the water-absorbing cotton ring 3 are better.

[0031] Two connecting plates 14 are provided at two locations in the length direction of the upper shell 1, and a plurality of connecting holes 15 are provided on the connecting plates 14. The connecting plates 14 of the upper shell 1 and the lower shell 2 can be connected by plastic bolts or by cable ties, and the plastic bolts and cable ties can be connected by passing through the connecting holes 15. A humidity sensor 10 is provided in each absorbent cotton ring 3, and the humidity sensor 10 is electrically connected to the monitoring device 5. The humidity sensor 10 is used to detect whether there is moisture in the absorbent cotton ring 3. When the humidity value detected by the humidity sensor 10 is abnormal, it means that there is water in the absorbent cotton ring 3, which means that the sealing rubber part 4 is damaged and needs to be repaired, so as to avoid damage and leakage of the sealing rubber part 4, which causes the monitoring device 5 to fail to monitor, or affects the monitoring effect of the monitoring device.

[0032] In this embodiment, an extended connection edge is further provided on the connection surface of the lower shell 2 to match the inner wall of the connection surface of the upper shell 1. The extended connection edge is designed as an integral unit with the lower shell 2, and the plug-in fit between the lower shell 2 and the upper shell 1 can be achieved through the extended connection edge, while the extended connection edge can further improve the sealing of the connection between the lower shell 2 and the upper shell 1.

[0033] Working principle and process: After the first tubular busbar 6 and the second tubular busbar 7 are connected through the connector 8, the installation ring 44 is first fixed at the set position of the first tubular busbar 6 and the second tubular busbar 7, and the absorbent cotton ring 3 and the sealing rubber member 4 are installed on the first tubular busbar 6 and the second tubular busbar 7. The outer ring of the absorbent cotton ring 3 is fixed in the absorbent cotton groove 13, the outer rubber ring 42 of the sealing rubber member 4 is fixed in the inner annular groove on the shell, and the inner rubber ring 41 of the sealing rubber member 4 is fixed in the outer annular groove on the shell. After all the absorbent cotton rings 3 and the sealing rubber members 4 are installed in place, the upper shell 1 and the lower shell are finally assembled. 2 are buckled together, and the upper shell 1 and the lower shell 2 are fixedly connected by passing the plastic bolt through the connection hole 15 on the connection plate 14. After the upper shell 1 and the lower shell 2 are fixedly connected, polyurethane foam or glue is dripped between the inner rubber ring 41 and the mounting ring 44 and between the outer rubber ring 42 and the sealing groove 12 to make the sealing rubber member 4 and the shell and the sealing rubber member 44 sealed. Finally, a layer of heat shrink film is put on the outer part of the upper shell 1 and the lower shell 2. The heat shrink film can further connect and fix the upper shell 1 and the lower shell 2, and at the same time reduce the contact area between the outer part of the upper shell 1 and the lower shell 2 and the outside world.
