[0020] The technical solutions of the present invention are further described below with reference to the accompanying drawings and through specific embodiments.

[0021] like Figure 1-2 As shown, the embodiment provides a riding well with high safety, which includes a riding well 2, a steel casing jacking pipe section 1, a top cover 3, and ventilation components. The riding well 2 is vertically connected with the steel casing pipe jacking section 1 . The steel sleeve jacking pipe section 1 is provided with an opening. The opening is provided in the riding well 2 . The top cover 3 is rotatably connected to the top of the riding well 2 . The ventilation components include an infrared sensor 41 , an oxygen sensor 42 , a blower, a processor 43 and a hydraulic rod 37 . The top cover 3 includes a cover body 31 , a surface plate 32 and a support rod 38 . The bottom of the face plate 32 is connected to the struts 38 . The lower end of the support rod 38 is inserted and matched with the cover body 31 . The bottom of the cover body 31 is provided with a groove 35 . The cover body 31 is provided with a plurality of ventilation holes 36 communicating with the grooves 35 . The hydraulic rod 37 is embedded in the middle of the cover body 31 . The upper end of the hydraulic rod 37 is connected to the surface plate 32 . The cover 31 is hinged to the top of the riding well 2 . The air blower includes a bracket 33 and an exhaust fan 34 . The exhaust fan 34 is fixed to the middle of the bracket 33 . One end of the bracket 33 is hinged to the upper end of the riding well 2 . The upper end of the riding well 2 is provided with a missing block 24 . The other end of the bracket 33 rests on the missing piece 24 . Both the infrared sensor 41 and the oxygen sensor 42 are arranged at the lower end of the inner wall of the horse riding well 2 . The infrared sensor 41 , the oxygen sensor 42 , the hydraulic rod 37 and the exhaust fan 34 are all electrically connected to the processor 43 .

[0022] Maintenance personnel open the top cover 3 and the bracket 33, and enter the well from the upper port of the riding well 2. After entering the well, if it is necessary to maintain the underground work for a long time, in order to maintain the ventilation of the well, the bracket 33 and the exhaust fan 34 are closed on the upper end of the horse-riding well 2, and the bracket 33 rests on the missing block 24. The maintenance personnel fall along the riding well 2 to the steel casing jacking pipe for maintenance. The infrared sensor 41 is in a normally open state. When the maintenance personnel fall to the horse-riding well 2, the infrared sensor 41 detects the temperature change in the well, and immediately transmits the signal to the processor 43, and the processor 43 receives the information sent by the infrared sensor 41. signal to control the activation of the oxygen sensor 42 . The oxygen sensor 42 detects the oxygen concentration at the bottom of the riding well 2 and feeds back the concentration data to the processor 43 in real time. When the oxygen concentration data received by the processor 43 reaches the preset minimum oxygen concentration value, the processor 43 links the exhaust fan 34 to blow air into the riding well 2 , and fresh air is injected into the riding well 2 through the exhaust fan 34 to improve the riding well 2 Oxygen content inside, to avoid maintenance personnel accidents due to lack of oxygen. During maintenance, it is sometimes necessary to close the top cover 3. When the ejector rods are closed, the processor 43 triggers the exhaust fan 34 and simultaneously links the hydraulic rod 37. The hydraulic rod 37 pushes up the surface plate 32 and the cover body 31 The ventilation holes 36 above are open, and the exhaust fan 34 can draw air through the ventilation holes 36 and discharge it into the riding well 2 . In this way, the ventilation of the riding well 2 is realized, and the sufficient oxygen in the working environment of the staff in the well is ensured. Improves the safety of the Riding Well 2 job. In this embodiment, the processor 43 is a commonly used processor 43 in the field, which can receive data information, and can transmit trigger signals to each device, and its model is not limited.

[0023] In an embodiment of the present invention, a pressure sensor 45 is provided at the bottom of the cover body 31 . The pressure sensor 45 is electrically connected to the processor 43 . When the cover 31 is closed on the riding well 2 , the pressure sensor 45 is pressed to transmit a pressure signal to the processor 43 . The processor 43 will not trigger the hydraulic rod 37 until the pressure sensor 45 is received, so as to avoid the phenomenon that the air in the well is not circulated and the fresh air cannot be replenished when the cover body 31 is closed.

[0024] In one embodiment of the present invention, a warning light 44 is embedded in the top of the surface plate 32 . When the surface plate 32 is lifted up by the hydraulic rod 37 , the warning light 44 is triggered at the same time, and the warning light 44 lights up to remind passing pedestrians on the ground to avoid tripping by the surface plate 32 .

[0025] In one embodiment of the present invention, the outer edge of the surface plate 32 is provided with a rain shield 321 which is inclined downward. The bottom of the surface plate 32 is provided with a concave ring 30 . The cover body 31 is provided with a convex ring 39 for protecting against rain. The male ring 39 is adapted to the female ring 30 . When the surface plate 32 is raised, if it rains, the rainwater falls on the surface plate 32, and the rainwater is guided around by the downwardly inclined rain-blocking edge 321. The ventilation holes 36 flow upward to avoid the influence of rainwater on maintenance personnel in the riding well 2 in a rainy environment.

[0026] In an embodiment of the present invention, a ladder 21 is provided on the inner wall of the riding well 2 from top to bottom. It is convenient for maintenance personnel to enter and exit the riding well 2 through the ladder 21 .

[0027] In one embodiment of the present invention, the high-safety riding well further includes a fall prevention net 22 . The anti-falling net 22 is hung inside the riding well 2 . The anti-falling net 22 can prevent maintenance personnel from accidentally falling and being injured when entering or leaving the horse-riding well 2 .

[0028] In one embodiment of the present invention, the safe riding well further includes a suction fan 55 and an exhaust duct 54 . The exhaust pipe 54 is embedded in the inner wall of the riding well 2 . The exhaust fan 55 is embedded in the inside of the riding well 2 . The lower end of the exhaust duct 54 communicates with the output end of the exhaust fan 55 . The upper end of the exhaust duct 54 extends outside the riding well 2 . The upper end of the exhaust pipe 54 is screwed with a cover 56 , and the exhaust fan 55 is electrically connected to the processor 43 . While the exhaust fan 34 is running, the processor 43 also triggers the exhaust fan 55 to run. The cover 56 is opened, and the exhaust fan 55 exhausts the air at the bottom of the riding well 2 through the exhaust pipe 54 to promote the air circulation in the riding well 2 . When the exhaust fan 55 does not need to operate, the cover 56 is screwed back to the upper end of the exhaust pipe 54, and the cover 56 seals the exhaust pipe 54 to prevent external dust and rainwater from entering the exhaust pipe 54 and affecting the riding well 2. various components inside. At the same time, in this embodiment, the height of the exhaust pipe 54 extending from the horse-riding well 2 is matched with the rain-blocking edge 321 , and when the rain-blocking edge 321 is lowered, it will not hit the exhaust pipe 54 .

[0029]In one embodiment of the present invention, a vertically arranged slide rail 51 is fixed to the side wall of the riding well 2 . A table 52 is slidably connected to the slide rail 51 . The bottom of the worktable 52 is clamped with an LED light 53 for lighting. The workbench 52 is convenient for users to place tools for maintenance, and the LED lights 53 can provide light for the dim environment at the bottom of the well, which is convenient for maintenance personnel to operate.

[0030] In an embodiment of the present invention, the high-safety riding well further includes a reinforcing rod 23 . The two ends of the reinforcing rod 23 are respectively connected with the outer wall of the horse-riding well 2 and the outer wall of the steel casing jacking pipe section 1 . The reinforcing rod 23 provides external support for the riding well 2, making it more firm and firm.
