Description

Technical Field

[0001] The present invention relates to the technical field of pipe gallery ventilation, and in particular to a ventilation monitoring device for multi-section joint operation in a pipe gallery. Background Art

[0002] Pipeline corridors are the primary locations for centralized pipeline installation and are constructed from steel or reinforced concrete columns, beams, and trusses. To improve efficiency, multi-stage joint operations are often employed during pipeline corridor construction. Ventilation is essential for the construction site, and ventilation monitoring equipment is required to monitor ventilation quality in real time.

[0003] Currently, ventilation monitoring equipment typically utilizes multiple sensors to monitor its surrounding environment, such as temperature, pressure, and flow rate, to ensure ventilation stability and safety during tunnel construction. However, sensors can malfunction over time, and if not detected promptly, this can affect the accuracy of detection results. To address this issue, the prior art discloses some sensors with self-testing capabilities, such as those disclosed in authorized patent documents such as CN201620396108.1 or CN202222219388.7.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts 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 fixed at one end of the device body 1, and the fixing block 9 facilitates the fixation of the device position. A monitoring structure is provided in the inner cavity of the device body 1, and the number and position of the monitoring structure can be set according to demand, without limitation. Figure 1 and attached Figure 2 shown.

[0029] The following is attached with the instruction manual Figure 1 Taking the ventilation monitoring equipment for multi-section joint operation in the shown pipeline corridor as an example, the present application is further explained.

[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 device body 1. 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 device body 1. The support plate 11 is located in the inner cavity of the device body 1. The vertical end of the support plate 11 is movably connected to a turntable 10. The turntable 10 and the fixed plate 2 are in a mutually parallel state. The middle part of the turntable 10 away from the fixed plate 2 is fixedly connected to a synchronous wheel 2 13. A servo motor 14 is fixed to one side of the support plate 11. The end of the output shaft of the servo motor 14 is fixed to a synchronous wheel 1 through a reducer. The synchronous wheel 1 and the synchronous wheel 2 are connected by 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 to it to rotate. The rotating synchronous wheel 1 can drive the synchronous wheel 2 13 to rotate through the synchronous belt. The synchronous wheel 2 13 can drive the turntable 10 fixedly connected to it to rotate.

[0031] 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 turntable 10 are in a tightly fitted state, and the rotation of the turntable 10 can drive the inner ring 19 to rotate. When the pressure plate 21 adapted to the outer sliding groove is tightly fitted with the outer ring 18 , the rotation of the turntable 10 can drive the outer ring 18 to rotate.

[0032] Described outer ring 18 and inner ring 19 both are all fixed with anti-skid pad near one side of fixed plate 2, and anti-skid pad material can be rubber. Through the setting of anti-skid pad, can increase the reliability of connection between outer ring 18 or inner ring 19 and rotating disk 10.

[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. The other end of the electric telescopic rod 15 is fixed to a device support plate 16. The other end of the device support plate 16 is fixed to a monitoring sensor 6. 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 pipeline corridor and the fixed plate 2 can be changed, and the monitoring sensor 6 can rotate under the action of the turntable 10.

[0035] A removable plate 3 is fixed to the middle of the fixed plate 2, and a transmission rod 20 is clamped to the middle of the turntable 10. The other end of the transmission rod 20 passes through the removable plate 3 and is fixedly connected to one end of the cleaning rod 7. The transmission rod 20 and the removable plate 3 are in a state of active connection. When the turntable 10 rotates, the cleaning rod 7 can be driven to rotate by the transmission rod 20. The cleaning rod 7 has a C-shaped structure, and the device body 1 has a cylindrical structure. The end of the cleaning rod 7 contacts the end of the device body 1, the middle of the cleaning rod 7 contacts the outer wall of the device body 1, and the end of the cleaning rod 7 is parallel to the turntable 10. Through the arrangement of the cleaning rod 7, the cleaning rod 7 can sweep away dust adhering to the device body 1 when it rotates, so that when cleaning the device body 1, no additional energy is consumed, saving resources, and the device body 1 can be cleaned automatically, reducing the workload of the staff.

[0036] The easily removable plate 3 is provided with through-holes 4 adapted for use with monitoring sensors 6 and a detection structure for testing monitoring sensors 6. The through-holes 4 and the detection structure are distributed circumferentially on the easily removable plate 3. Under the action of an electrically operated telescopic rod 15, the monitoring sensor 6 can be inserted into the through-holes 4, exposing the monitoring end of the monitoring sensor 6 to the air, facilitating real-time monitoring of the surrounding environment by the monitoring sensor 6. Preferably, there are two monitoring sensors 6 and two through-holes 4. This arrangement ensures that when replacing a monitoring sensor or performing a performance test on the detection sensor, there is always a monitoring sensor 6 monitoring the surrounding environment, avoiding gaps in the ventilation monitoring device and ensuring the reliability of the device.

[0037] A sealing airbag 8 is fixed on 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 extrusion 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 a 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 for 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 sealing gaskets. The sealing gasket material can be rubber. 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 provided in the sealed cavity. The sealing plate 24 is provided with a through hole 25. The through hole 25 is sealed by a rotating plate 26. The rotating plate 26 is movably connected to the side of the sealing plate 24 away from the insertion cavity. A rotating motor 23 is fixedly connected to the sealed cavity. The end of the output shaft of the rotating motor 23 is fixedly connected to the rotating plate 26 via 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 to it to rotate, and the rotating plate 26 can block the through hole 25. When the rotating plate 26 is staggered with the through hole 25, 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 to determine whether the performance of the monitoring sensor 6 is reliable.

[0039] When monitoring sensor 6 detects the concentration of a substance in the air, the substance to be detected in the sealed chamber is air containing the substance, and the concentration of the substance in the air is known. For example, if monitoring sensor 6 detects the concentration of carbon monoxide in the air, the substance to be detected in the sealed chamber contains 100 ppm. By comparing the carbon monoxide concentration detected by monitoring sensor 6 with the recorded carbon monoxide concentration, the reliability of monitoring sensor 6 can be determined. For example, when monitoring sensor 6 is a temperature sensor, the substance to be detected in the sealed chamber is heater 22. When heater 22 is powered on, the heat emitted can heat the surrounding area. If heater 22 has a fixed power and a fixed operating time, the temperature of the air in the sealed chamber can be determined. Therefore, by calculating the operating time of heater 22, the temperature in the sealed chamber can be determined using this device. By comparing the temperature value detected by monitoring sensor 6 with the actual temperature value in the sealed chamber, the reliability of monitoring sensor 6 can be determined.

[0040] The electrical components involved in this application are all existing technologies. Those skilled in the art are familiar with their connection methods. Through these people, all the electrical components in this application are connected to their corresponding power supplies through wires, and according to actual conditions, appropriate controllers are selected to meet control requirements. The specific connections and control sequences are described below. The electrical connections between the electrical components are completed in a sequential working order. The detailed connection methods are well known in the art. The following mainly introduces the working principles and processes, and no further explanation of 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. Fitting, the servo motor 14 drives the turntable 10 to rotate, the turntable 10 drives the inner ring 19 to rotate, and the inner ring 19 drives the monitoring sensor 6 connected thereto to rotate, changing the position of the monitoring sensor 6 until the monitoring sensor 6 can be inserted into the insertion cavity, and 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, and the rotating plate 26 is rotated under the action of the rotating motor 23 until the through hole 25 is in an open state, and the monitoring sensor 6 can detect the substance to be tested, and the reliability of the monitoring sensor 6 can be judged according to the test results. 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.
