Description

Technical Field

[0001] The present invention relates to the technical field of power manhole detection equipment, and particularly relates to a plug-in gas detection device for power manholes. Background Art

[0002] In recent years, with the large-scale implementation of urban power grid transformation, the application of power manholes for connecting cable channels has become increasingly widespread. The power transmission lines are very complex, and there are often some harmful gases remaining in the power manholes (such as hydrogen sulfide, methane, carbon monoxide, oxygen, etc.). These harmful gases in the well cause great difficulties for maintenance workers during maintenance. Currently, in order to protect the personal safety of power manhole workers, various types of detection equipment and instruments have been configured from various aspects at the national, industrial, and enterprise levels. Therefore, gas detection in the well needs to be carried out before the power manhole exploration work.

[0003] Most of the existing gas detection devices are mainly carried around. When workers are operating, the devices are carried on the workers' bodies, which causes great inconvenience for workers to go down the well. Moreover, with the continuous development of urban modernization, the number of various wells is also increasing continuously. If this method is still used to detect various indicators of gases, the work efficiency is low. Coupled with the unfamiliarity with the use method of the instruments, it is very difficult for underground workers to ensure their personal safety. Therefore, we propose a plug-in gas detection device for power manholes to solve the above problems. Summary of the Invention

[0004] The present invention specifically adopts the following technical solutions to achieve the above objectives: A plug-in gas detection device for power manholes, comprising: A detection unit for detecting gases in a power manhole. The detection unit includes an installation cylinder. One end of the installation cylinder is open, and a hollow column is detachably and pluggably arranged inside it. An RF module is installed on one side inside the hollow column. A detection sensor is installed in the middle of the end of the hollow column located outside the installation cylinder, and cameras are annularly arranged on its side. A control unit for controlling the orientation of the detection unit. The control unit includes a hollow disk and a connecting pipe connected to one end of the installation cylinder. A connecting rod is provided at the end of the connecting pipe away from the installation cylinder. An extension pipe communicates with one end of the hollow disk. The connecting rod and the extension pipe are threadedly connected. A rotating rod is rotatably connected to the middle of the hollow disk. A winding wheel is fixedly provided in the middle of the rotating rod. A traction rope is wound in the wheel groove of the winding wheel. The free end of the traction rope is connected to the connecting rod. A hand-held pipe communicates with the end of the hollow disk away from the extension pipe. A locking member for preventing the winding wheel from rotating is provided inside the hand-held pipe. A control panel is installed on one side of the surface of the hollow disk. The control panel is network-connected to the cameras and the detection sensor through the RF module. A display screen is provided on the surface of the control panel.

[0005] Furthermore, supplementary light lamps are arranged in an annular array on the side of the end of the installation cylinder where the detection sensor is located.

[0006] Furthermore, the detection sensor is one of a combustible gas detection sensor, an oxygen detection sensor, a carbon monoxide detection sensor, and a hydrogen sulfide detection sensor.

[0007] Furthermore, a storage battery is installed inside the hollow column on the side of the RF module.

[0008] Furthermore, connecting columns are symmetrically and fixedly arranged on both sides of the hollow column. An arc-shaped notch is symmetrically constructed on one side of the installation cylinder near the port, and the connecting columns are slidably inserted into the arc-shaped notch.

[0009] Furthermore, an elastic rubber pad is arranged on the inner top wall of the installation cylinder.

[0010] Furthermore, the end of the rotating rod far from the control panel penetrates through the hollow disk and is connected with a knob.

[0011] Furthermore, the connecting pipe is a gooseneck pipe.

[0012] Furthermore, the locking member includes a movable disk slidably arranged inside the handheld tube. A spring is connected between the movable disk and the inner bottom wall of the handheld tube. A triangular clamping block is fixedly arranged on the side of the movable disk far from the spring. Triangular notches are constructed in an annular array on the side of the wire winding wheel. The triangular clamping block is adapted to the size of the triangular notches. A strip-shaped channel is constructed on one side of the handheld tube near the hollow disk. A dial fixedly arranged on the surface of the movable disk penetrates through the strip-shaped channel.

[0013] Furthermore, a rubber sleeve is sleeved on the surface of the handheld tube, and anti-slip patterns are constructed in the middle of the hollow column.

[0014] The beneficial effects of the present invention are as follows: In the present invention, the hollow column and the installation cylinder are connected in a plug-and-play manner, which not only facilitates the replacement of the detection sensor by the staff, but also makes the equipment maintenance and management more convenient. When in use, insert the hollow column into the installation cylinder, and by rotating the hollow column, the connecting column can be embedded into the deepest part of the arc-shaped notch, and the rapid installation of the equipment can be completed. The operation is very simple.

The staff operates the handheld pipe, and the detection sensor at the end of the hollow column can be extended to a shallower position in the power manhole for detection; when gas detection is carried out at a deeper position in the power manhole, the connecting rod and the extension pipe can be separated first, and the traction rope is pulled outwards so that the hollow column falls to the designated depth in the power manhole. Then, the winding wheel is prevented from rotating through the locking member, so that gas detection can be stably carried out at the designated depth position in the power manhole. The staff can complete the gas detection work without entering the power manhole, which is safer and more reliable.

[0016] When the present invention is in use, the camera on the surface of the hollow column can provide visual images to help the staff observe the actual situation in the power manhole.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] This application provides a plug-in gas detection device for power manholes, mainly used to solve the problem that most of the existing gas detection devices are mainly carried around. When workers are operating, the devices are carried on the workers' bodies, which causes great inconvenience for workers to enter the manhole. The following technical solutions are provided. The following will be combined with Figures 1-5 be described in detail: A plug-in gas detection device for power manholes, comprising: A detection unit for detecting gas in a power manhole. The detection unit includes an installation cylinder 1. One end of the installation cylinder 1 is open, and a hollow column 2 is detachably and pluggably arranged inside it. Connecting columns 201 are symmetrically fixed on both sides of the hollow column 2. An arc-shaped notch 101 is symmetrically formed on one side of the installation cylinder 1 near the port. The connecting column 201 slides through the arc-shaped notch 101. An RF module 3 is installed on one side inside the hollow column 2. A detection sensor 4 is installed in the middle of the end of the hollow column 2 outside the installation cylinder 1, and cameras 5 are arranged in an annular array on its side. A control unit for controlling the orientation of the detection unit. The control unit includes a hollow disk 6 and a connecting pipe 7 connected to one end of the installation cylinder 1. A connecting rod 8 is arranged at the end of the connecting pipe 7 away from the installation cylinder 1. An extension pipe 9 communicates with one end of the hollow disk 6. The connecting rod 8 and the extension pipe 9 are threadedly connected. A rotating rod 10 is rotatably connected to the middle of the hollow disk 6. A winding wheel 11 is fixed in the middle of the rotating rod 10. A traction rope 12 is wound in the groove of the winding wheel 11. The free end of the traction rope 12 is connected to the connecting rod 8. A hand-held pipe 13 communicates with the end of the hollow disk 6 away from the extension pipe 9. A locking member 14 for preventing the winding wheel 11 from rotating is arranged inside the hand-held pipe 13. A control panel 15 is installed on one side of the surface of the hollow disk 6. The control panel 15 is network-connected to the cameras 5 and the detection sensor 4 through the RF module 3. A display screen 16 is arranged on the surface of the control panel 15.

[0021] Specific implementation steps and principle explanations of the plug-in gas detection device for power manholes: First step, switch the state of the control unit as needed. The specific method is as follows: When detecting gas in the shallower part of the power manhole, the connecting rod 8 and the extension pipe 9 can be screwed together. The staff operates the hand-held pipe 13, and the detection sensor 4 at the end of the hollow column 2 can be extended to the shallower position of the power manhole for detection; When detecting gas in the deeper part of the power manhole, the connecting rod 8 and the extension pipe 9 can be separated first. Pull the traction rope 12 outwards so that the hollow column 2 drops to the specified depth of the power manhole. Then, the locking member 14 is used to prevent the winding wheel 11 from rotating, so that the gas can be stably detected at the specified depth position of the power manhole. The staff can complete the gas detection work without entering the power manhole deeply, which is safer and more reliable; In the second step, during specific implementation, the camera 5 on the surface of the hollow column 2 can provide visual images to help the staff observe the actual situation inside the power manhole. The detection sensor 4 can detect specific gases inside the power manhole, such as combustible gas, oxygen, carbon monoxide, or hydrogen sulfide, etc. If harmful gases are detected, the display screen 16 on the control panel 15 will prompt relevant information and can also emit sound or light signals as needed to remind the staff to pay attention to safety.

[0022] The design of this plug-in gas detection device for power manholes makes the operation safer and more convenient, avoiding the danger of staff entering the power manhole for gas detection.

[0023] Such as Figure 5 As shown, in some embodiments, supplementary lights 17 are arranged in an annular array on the side of the end of the mounting cylinder 1 where the detection sensor 4 is located. More specifically, this design is usually used to provide light sources to enhance the visual effect of the camera 5. The function of the supplementary lights 17 is to provide additional light in low light or dark areas so as to capture or monitor the target area more clearly. Specifically, the annular array of supplementary lights 17 can be evenly distributed around the detection sensor 4 to ensure that the light can illuminate the target area in all directions. This design can provide a uniform and stable light source to reduce the impact of shadows and uneven light on the image quality.

[0024] Such as Figure 5 As shown, in some embodiments, the detection sensor 4 is one of a combustible gas detection sensor 4, an oxygen detection sensor, a carbon monoxide detection sensor 4, and a hydrogen sulfide detection sensor 4. More specifically, The combustible gas detection sensor 4 is usually used to detect combustible gases inside the power manhole, such as natural gas, liquefied petroleum gas, etc. When these gases are detected, the sensor will emit an alarm signal so that the staff can take necessary safety measures in time; The oxygen detection sensor 4 is usually used to detect the oxygen concentration inside the power manhole to ensure that the oxygen concentration reaches a safe level in the working area. If the oxygen concentration is lower than the safety standard, the sensor will emit an alarm signal so that the staff can take appropriate measures; The carbon monoxide detection sensor 4 is usually used to detect the carbon monoxide concentration inside the power manhole because carbon monoxide is a colorless, odorless, and toxic gas. Once the detected carbon monoxide concentration exceeds the safety limit, the sensor will emit an alarm signal so that the staff can take necessary measures; The hydrogen sulfide detection sensor 4 is usually used to detect the hydrogen sulfide concentration inside the power manhole because hydrogen sulfide is a colorless and toxic gas with a strong pungent odor. Once the detected hydrogen sulfide concentration exceeds the safety standard, the sensor will emit an alarm signal so that the staff can take necessary measures; It should be noted that in the present invention, a plurality of hollow columns 2 are provided, and a specific detection sensor 4 is installed on each hollow column 2, and the staff can install it according to actual needs.

[0025] As Figure 5 shown, in some embodiments, a storage battery 18 is installed on the side of the RF module 3 inside the hollow column 2. More specifically, the storage battery 18 is a device that can convert chemical energy into electrical energy and release it when needed. Installing the storage battery 18 inside the hollow column 2 can achieve continuous power supply for the electrical equipment on the hollow column 2 and ensure the normal operation of the equipment. It should be noted that the control panel 15 is powered separately. The control panel 15 is a prior art, and one of the product models is XBT-6GC, and its circuit connection will not be elaborated.

[0026] As shown in FIG. 5, in some embodiments, an elastic rubber pad 19 is provided on the inner top wall of the mounting cylinder 1. More specifically, the elastic rubber pad 19 plays a buffering role and protects the components on the hollow column 2. In addition, after the hollow column 2 is connected to the mounting cylinder 1, it is more stable and not easy to fall off.

[0027] As Figure 4 shown, in some embodiments, one end of the rotating rod 10 away from the control panel 15 passes through the hollow disk 6 and is connected to a knob. More specifically, the knob on the control panel 15 is used to facilitate the staff to rotate the winding wheel 11 to realize the winding and releasing of the traction rope 12. Such a design allows the staff to more easily control the rotation speed and direction of the winding wheel 11, thereby completing the winding and releasing operations of the traction rope 12.

[0028] As Figure 1 shown, in some embodiments, the connecting pipe 7 is a gooseneck pipe. More specifically, by setting the gooseneck pipe, the staff can direct the gas detector to a specific position or angle according to needs to better monitor the gas situation in the target area. The bent shape and flexibility of the gooseneck pipe make it easier to adjust the orientation and can adapt to different working environments and requirements.

[0029] As Figure 4As shown, in some embodiments, the locking member 14 includes a movable disk 1401 slidably disposed inside the hand-held tube 13. A spring 1402 is connected between the movable disk 1401 and the inner bottom wall of the hand-held tube 13. A triangular latch 1403 is fixedly provided on the side of the movable disk 1401 away from the spring 1402. Triangular notches 1101 are annularly arranged on the side of the winding wheel 11. The triangular latch 1403 and the triangular notches 1101 are of suitable sizes. A strip-shaped channel is formed on the side of the hand-held tube 13 close to the hollow disk 6. A dial 1404 penetrating the strip-shaped channel is fixedly provided on the surface of the movable disk 1401. More specifically, by pulling the dial 1404, the movable disk 1401 compresses the spring 1402 and moves, so that the triangular latch 1403 disengages from the triangular notches 1101, releasing the locked state. When the dial 1404 is released, the slider and the movable disk 1401 will reset under the action of the tension spring, causing the triangular latch 1403 to re-insert into the triangular notches 1101 to achieve the locking function.

[0030] As Figure 4 shown, in some embodiments, a rubber sleeve 1301 is sleeved on the surface of the hand-held tube 13, and anti-slip lines 202 are formed in the middle of the hollow column 2. More specifically, the rubber sleeve 1301 can improve the comfort and anti-slip performance of the hand-held tube 13, making the worker more stable and safe when operating the device. The rubber sleeve 1301 can be made of materials with wear resistance, oil resistance, acid and alkali resistance, etc. to adapt to the special environment of the electric power manhole. The anti-slip lines 202 in the middle of the hollow column 2 can increase the holding force of the hand on the hollow column 2 and improve the stability of the operation. The anti-slip lines 202 can adopt uneven patterns or thread-like structures to increase the friction force and prevent the hand from slipping. Through the design of the rubber sleeve 1301 and the anti-slip lines 202, the worker can be more comfortable and stable when operating the device, improving the work efficiency and safety.

[0031] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
