[0002] The pipe gallery is the main place for the centralized laying of pipelines, and is composed of columns, beams and trusses of steel or reinforced concrete structures. In the process of pipe gallery construction, in order to improve the construction efficiency of the pipe gallery, multi-section joint operation is often used for construction. During the construction of the pipe gallery, the construction site needs to be ventilated, and in the process of ventilating the construction site, ventilation monitoring equipment is needed to monitor the ventilation quality in real time.

[0003] At present, when ventilation monitoring equipment is used, multiple sensors are usually used to detect the surrounding environment, such as temperature, pressure, flow, etc., so as to ensure the stability and safety of ventilation during the construction of the tunnel. However, the sensor may fail during long-term operation. If it is not discovered in time, it will affect the accuracy of the detection result. In response to this problem, some sensors with self-checking functions are disclosed in the prior art, such as the schemes disclosed in the authorized patent documents of CN201620396108.1 or CN202222219388.7. These types of sensors are provided with detection circuits inside to perform self-checks on the operating status of the sensor.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The present invention provides a ventilation monitoring device for multi-section joint operation in a pipe gallery, comprising a device body 1, a fixing block 9 is fixed at one end of the device body 1, and the fixing block 9 facilitates the fixing of the position of the device. A monitoring structure is arranged in the inner cavity of the device body 1, and the number and position of the monitoring structure can be set according to the requirements, and are not limited here. Figure 1 and attached Figure 2 shown.

[0029] The following is the instruction manual Figure 1 The present application is further explained by taking the ventilation monitoring equipment for multi-section joint operation in the shown pipe corridor as an example.

[0030] As the instruction manual Figure 1 , Instruction Manual Figures 3 to 8As shown, in this embodiment, the monitoring structure is located at the end of the inner cavity of the equipment body 1, and the monitoring structure includes a fixed plate 2 and a support plate 11. The fixed plate 2 is fixedly connected to the shell of the equipment body 1, and the support plate 11 is located in the inner cavity of the equipment body 1. The vertical end of the support plate 11 is movably connected with a turntable 10, and the turntable 10 and the fixed plate 2 are in a state of being parallel to each other. The middle part of the turntable 10 away from the fixed plate 2 is fixedly connected with a synchronous wheel 2 13, and a servo motor 14 is fixed on one side of the support plate 11. The end of the output shaft of the servo motor 14 is fixed with a synchronous wheel 1 through a reducer, and the synchronous wheel 1 and the synchronous wheel 2 are connected through a synchronous belt transmission. Through the setting of the servo motor 14, the rotation of the servo motor 14 can drive the synchronous wheel 1 fixedly connected thereto to rotate, and the rotating synchronous wheel 1 can drive the synchronous wheel 2 13 to rotate through the synchronous belt, and the synchronous wheel 2 13 can drive the turntable 10 fixedly connected thereto to rotate.

[0031] The rotating disk 10 is provided with an inner groove and an outer groove on one side close to the fixed plate 2, and an inner ring 19 is movably connected in the inner cavity of the inner groove, and an outer ring 18 is movably connected in the inner cavity of the outer groove. A movable groove is provided at one end of the inner groove and the outer groove, and a pressing structure is provided in the inner cavity of the movable groove, and the pressing structure includes a pressure plate 21 movably connected to the inner cavity of the movable groove, and one end of the pressure plate 21 away from the fixed plate 2 is fixedly connected to the output end of the electric telescopic rod 21, and the other end of the electric telescopic rod 12 is fixedly connected to the rotating disk 10. Through the setting of the electric telescopic rod 21, the extension and contraction of the electric telescopic rod 12 can change the position of the pressure plate 21 fixedly connected thereto. When the pressure plate 21 adapted to the inner groove is tightly fitted with the inner ring 19, the pressure plate 21 can press the inner ring 19, so that the inner ring 19 and the rotating disk 10 are in a tightly fitted state, and the rotation of the rotating disk 10 can drive the inner ring 19 to rotate. When the pressure plate 21 matched with the outer slide groove is tightly fitted with the outer ring 18, the rotation of the rotating disk 10 can drive the outer ring 18 to rotate.

[0032] The outer ring 18 and the inner ring 19 are both fixed with anti-skid pads on one side close to the fixed plate 2. The anti-skid pads can be made of rubber. The reliability of the connection between the outer ring 18 or the inner ring 19 and the rotating disk 10 can be increased by the provision of the anti-skid pads.

[0033] An electric telescopic rod 15 is fixed to one side of the outer ring 18 and the inner ring 19 close to the fixed plate 2, and a device support plate 16 is fixed to the other end of the electric telescopic rod 15, and a monitoring sensor 6 is fixed to the other end of the device support plate 16. Through the setting of the electric telescopic rod 15, the extension and retraction of the electric telescopic rod 15 can change the position of the monitoring sensor 6 fixedly connected thereto.

[0034] From the above description, it can be seen that the position between the monitoring sensor 6 used to detect the ventilation quality of the multi-section joint operation site of the corridor and the fixed plate 2 can be changed, and the monitoring sensor 6 can rotate under the action of the turntable 10.

[0035] The middle of the fixed plate 2 is fixed with an easily removable plate 3, and the middle of the rotating disk 10 is clamped with a transmission rod 20. The other end of the transmission rod 20 penetrates the easily removable plate 3 and is fixedly connected with one end of the cleaning rod 7. The transmission rod 20 and the easily removable plate 3 are in a state of active connection. When the rotating disk 10 rotates, the cleaning rod 7 can be driven to rotate by the transmission rod 20. The cleaning rod 7 is a C-shaped structure, and the equipment body 1 is a cylindrical structure. The end of the cleaning rod 7 contacts the end of the equipment body 1, and the middle of the cleaning rod 7 contacts the outer side wall of the equipment body 1. The end of the cleaning rod 7 and the rotating disk 10 are in a state of being parallel to each other. Through the setting of the cleaning rod 7, the cleaning rod 7 can sweep away the dust adhering to the equipment body 1 when it rotates, so that when cleaning the equipment body 1, no additional energy is consumed, resources are saved, and the equipment body 1 can be cleaned by itself, reducing the workload of the staff.

[0036] The easily removable plate 3 is provided with a through hole 4 adapted to the monitoring sensor 6 and a detection structure for detecting the monitoring sensor 6. The through hole 4 and the detection structure are distributed in a circumference on the easily removable plate 3. Under the action of the electric telescopic rod 15, the monitoring sensor 6 can be inserted into the through hole 4, and the monitoring end of the monitoring sensor 6 can be exposed to the air, so that the monitoring sensor 6 can monitor the surrounding environment in real time. And preferably, the number of the monitoring sensors 6 is two, and the number of the through holes 4 is two. Such an arrangement makes it possible for the monitoring sensor 6 to monitor the surrounding environment at all times when the monitoring sensor is replaced or the detection sensor is tested for performance, so as to avoid the occurrence of a monitoring blank section in the ventilation monitoring device and ensure the reliability of the device.

[0037] A sealing airbag 8 is fixed to the side of the through hole 4 close to the turntable 10, and a accommodating hole adapted to the monitoring sensor 6 is provided on the sealing airbag 8. The end of the accommodating hole away from the through hole 4 is a conical structure. When the accommodating hole is separated from the monitoring sensor 6, the end of the accommodating hole close to the through hole 4 is in a tightly fitted state, and the material of the sealing airbag 8 is an elastic material, such as rubber. When the monitoring sensor 6 is inserted into the accommodating hole, the accommodating hole can be in an expanded state under the squeeze of external force, and the monitoring sensor 6 can be inserted into the through hole 4. When the monitoring sensor 6 is separated from the accommodating hole, under the action of the rebound force of the sealing airbag 8, the end of the accommodating hole away from the turntable 10 is in a tightly fitted state. At this time, the sealing airbag 8 can block the tube through hole 4 to prevent external impurities from entering the inner cavity of the equipment body 1.

[0038] The detection structure includes a sealing box 5 fixed to the easily removable plate 3, a sealing plate 24 is fixed to the side of the sealing box 5 close to the monitoring sensor 6, the inner cavity of the sealing plate 24 divides the inner cavity of the sealing box 5 into a sealing cavity and an insertion cavity adapted to the monitoring sensor 6, under the action of the electric telescopic rod 15, the monitoring end of the monitoring sensor 6 can be inserted into the insertion cavity, the inner wall of the insertion cavity and the side of the sealing plate 24 close to the insertion cavity are fixed with a sealing gasket, the material of the sealing gasket can be rubber, and the sealing gasket is used to increase the sealing between the monitoring sensor 6 and the insertion cavity to avoid leakage. The substance to be tested is arranged in the sealing cavity, and the sealing plate 24 is provided with a through hole 25, the through hole 25 is sealed by a rotating plate 26, and the rotating plate 26 is movably connected to the side of the sealing plate 24 away from the insertion cavity, and a rotating motor 23 is fixedly connected in the sealing cavity, and the end of the output shaft of the rotating motor 23 is fixedly connected to the rotating plate 26 through a reducer. Through the setting of the rotating motor 23, the rotation of the rotating motor 23 can drive the rotating plate 26 fixedly connected thereto to rotate, and the rotating plate 26 can block the through hole 25. When the rotating plate 26 and the through hole 25 are staggered, the through hole 25 is in an open state. When the through hole 25 is open, the monitoring sensor 6 can monitor the substance to be tested, and compare the detected information with the recorded information of the substance to be tested, so as to determine whether the performance of the monitoring sensor 6 is reliable.

[0039] When the monitoring sensor 6 detects the concentration of a substance in the air, the substance to be detected in the sealed cavity is air containing a substance, and the concentration of the substance in the air is known. For example, the monitoring sensor 6 detects the concentration of carbon monoxide in the air, and the substance to be detected in the sealed cavity contains 100 ppm. By comparing the carbon monoxide concentration detected by the monitoring sensor 6 with the recorded carbon monoxide concentration, the reliability of the monitoring sensor 6 can be determined. For example, when the monitoring sensor 6 is a sensor for detecting temperature, the substance to be detected in the sealed cavity is a heater 22. When the heater 22 is powered on, the heat emitted can heat the temperature around it. When the working time of the heater 22 with a certain power is fixed, the temperature of the air in the sealed cavity can be determined. Therefore, the temperature in the sealed cavity can be determined by calculating the working time of the heater 22 through the device. By comparing the temperature value monitored by the monitoring sensor 6 with the actual temperature value in the sealed cavity, it can be determined whether the monitoring sensor 6 is reliable.

[0040] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0041] To sum up: when the ventilation monitoring equipment for multi-section joint operation of the corridor is used, the ventilation monitoring equipment is fixed at a suitable position at the multi-section construction site of the corridor. When the ventilation monitoring equipment is in use, the monitoring sensor 6 is used to monitor the surrounding environment in real time. If the monitoring sensor 6 connected to the inner ring 19 detects the surrounding environment, and the other monitoring sensor 6 connected to the outer ring 18 is in a non-working state, and it is necessary to detect the reliability of the monitoring sensor 6, the other monitoring sensor 6 is inserted into the through hole 4 under the action of the extension of the electric telescopic rod 15 connected to it, and the monitoring sensor 6 is separated from the through hole 4 under the action of the contraction of the electric telescopic rod 15, and the other monitoring sensor 6 can detect the surrounding environment, and the pressure plate 21 adapted to the inner ring 19 is tightly connected to the inner ring 19 The servo motor 14 drives the turntable 10 to rotate, the turntable 10 drives the inner ring 19 to rotate, the inner ring 19 drives the monitoring sensor 6 connected thereto to rotate, and changes the position of the monitoring sensor 6 until the monitoring sensor 6 can be inserted into the insertion cavity. The monitoring sensor 6 is inserted into the insertion cavity under the action of the electric telescopic rod 15 adapted thereto, until the monitoring end of the monitoring sensor 6 is tightly fitted with the sealing plate 24, the rotating plate 26 rotates under the action of the rotating motor 23 until the through hole 25 is in an open state, the monitoring sensor 6 can detect the substance to be detected, and the reliability of the monitoring sensor 6 can be judged according to the detection result. If the monitoring sensor 6 is unreliable, the equipment can use an alarm to remind the staff to replace the monitoring sensor 6 in time. When the monitoring sensor 6 is reliable, the monitoring sensor 6 is reset.

[0042] In addition, during the rotation of the turntable 10, the turntable 10 connected to the cleaning rod 7 drives the transmission rod 20 to rotate, and the transmission rod 20 drives the cleaning rod 7 to rotate. During the rotation of the cleaning rod 7, the dust adhering to the outer surface of the equipment body 1 can be scraped off, which is convenient for heat dissipation of the equipment.
