Description

Technical Field

[0001] The present invention relates to the technical field of substation environment detection, and in particular to a substation environment detection device. Background Art

[0002] Substation is an important part of the power system. It is a place to change voltage and distribute electric energy. Its basic principle is to use transformers to increase or decrease voltage. There may be corrosive gases in the environment around the substation, such as sulfur dioxide, hydrogen sulfide, hydrogen chloride, etc., and some equipment in the substation itself also contains specific gases, such as sulfur hexafluoride circuit breakers. Sulfur hexafluoride gas has excellent arc extinguishing performance and insulation performance. When the circuit breaker is working normally, it can effectively extinguish the arc and ensure the insulation of the equipment. However, if the equipment fails, such as internal arc discharge, sulfur hexafluoride gas will decompose to produce toxic and harmful decomposition products such as thionyl fluoride and sulfur tetrafluoride. These decomposition products may corrode the metal parts inside the equipment and reduce the insulation performance of the equipment. If not detected and handled in time, it may cause more serious equipment failures or even cause equipment explosions. In the substation, sulfur hexafluoride gas leakage may occur due to poor sealing or improper operation, and sulfur hexafluoride gas leakage may also occur in the equipment itself due to aging of the equipment. Therefore, it is very important to detect sulfur hexafluoride gas in the substation, and in the prior art, inspection vehicles are mostly used to conduct inspections in the substation.

[0003] The inspection cart used in the prior art has deficiencies in gas collection during the inspection process. Currently, gas is collected and tested by using a fan to extract gas. The fan detection method will produce air convection during the gas extraction process. Therefore, there is a situation where the extracted air leaks during the process of using the fan to extract air, and the collected air cannot be sealed and stored. The detection process needs to be in a sealed state to ensure the accuracy of the detection. Using a fan to extract will cause air convection and poor sealing. Therefore, there are errors in the detection process, which affects the effective detection of the gas.

[0004] For example, a substation indoor environment greenhouse detection device and its use method disclosed in the Chinese patent with announcement number CN115436579A collects gas by using the process of fan extraction. Its working principle is: "The driving gear on the detection component motor drives the rotation of the transmission gear on the transmission shaft, and then the monitor transmitter and the monitor reflector are rotated upward to the inside of the reflective plate bin and the reflective plate bin, and the gas inside the vent is replaced under the action of the motor inside the connector; then, under the action of the detection component motor, the monitor transmitter and the monitor reflector on the gas monitor component are rotated downward to seal the vent. ; By starting the monitor and making the detector receiving circle receive the light reflected by the detection emission source through the reflective end of the monitor, the gas in the air is detected. "The method used is to use the start of the motor to drive the impeller to rotate and generate suction, so that the gas in the air hole is discharged and ventilated with the outside air. The air hole, the exhaust hole and the suction groove are in a connected state, and the suction groove is in a connected state with the outside air. When gas flows into the air hole, air convection will be generated from the suction groove, resulting in the gas in the air hole cannot be sealed. During the detection process, other gases will enter or be discharged, affecting the accuracy of gas detection. Summary of the invention

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] Example 1

[0034] Please refer to Figure 1-Figure 13 As shown, the present invention provides a substation environment detection device, including an inspection vehicle 1, a support slide 3 and a fixed box 33, the four corners of the top surface of the inspection vehicle 1 are fixedly connected to the limit slide bar 12, and the support slide 3 is slidably arranged up and down on the periphery of the limit slide bar 12;

[0035] The top surface of the inspection vehicle 1 is provided with an elastic mechanism elastically connected to the supporting slide plate 3;

[0036] The inspection vehicle 1 is provided with a pulling mechanism for pulling the supporting slide plate 3 downward, and the pulling mechanism is rotated and inserted into the bottom surface of the supporting slide plate 3;

[0037] The fixed box 33 is fixedly arranged on the top surface of the supporting slide plate 3, and an air guide mechanism is arranged on the inner wall of the fixed box 33, and air inlets 521 are opened near the edges on both sides of the air guide mechanism;

[0038] The bottom surface of the air guide mechanism is provided with a blocking mechanism for intermittently blocking the air inlet 521, and the air guide mechanism is provided with a pressing mechanism for pressing and driving the blocking mechanism to rotate;

[0039] The top surface of the supporting slide plate 3 is provided with a detection mechanism for detecting the gas flowing into the gas storage cavity surrounded by the fixed box 33 and the gas guide mechanism.

[0040] In the present case, the limit slide bar 12 is fixedly arranged at the four corners of the inspection vehicle 1, and the support slide plate 3 is slidably arranged on the periphery of the limit slide bar 12 up and down, wherein an elastic mechanism and a pulling mechanism are arranged between the inspection vehicle 1 and the support slide plate 3, and the supporting slide plate 3 can be pulled downward by the pulling mechanism so that the supporting slide plate 3 presses the elastic mechanism downward, and under the limiting action of the limit slide bar 12, the stable downward pressure of the supporting slide plate 3 can be ensured to avoid the swinging of the supporting slide plate 3 during the downward movement, and the pulling mechanism is rotated and interspersed on the bottom surface of the supporting slide plate 3, and the pulling mechanism can generate a downward pulling force on the supporting slide plate 3 when sliding inside the supporting slide plate 3, so as to When the support slide 3 is pulled to a low position, the pulling mechanism passes through the support slide 3 and is released from the pulling force on the support slide 3. At this time, the compression of the elastic mechanism by the support slide 3 will cause the elastic mechanism to be in a compressed state. When the support slide 3 is released from the pulling force, the elastic force of the elastic mechanism will instantly release the elastic force to bounce the support slide 3 upward. After bouncing up, due to the effect of inertia, the support slide 3 is released from the contact with the elastic mechanism and slides upward along the limiting slide bar 12, so that the support slide 3 has an upward impact sliding process, wherein the fixing box 33 and the detection mechanism are fixedly arranged on the top surface of the support slide 3, and the air guide mechanism is fixedly arranged on the fixing box 33. 3, the pressing mechanism is arranged on the air guide mechanism, and when the supporting slide plate 3 slides upward, the fixed box 33, the air guide mechanism, the pressing mechanism and the detecting mechanism all slide upward, so when the supporting slide plate 3 impacts and slides upward, it will be subject to the resistance of the air pressure, so that the pressing mechanism will have a downward pressing force, so that the pressing mechanism presses downward, wherein the air guide mechanism is provided with a pressing mechanism for driving the blocking mechanism to rotate, so when the pressing mechanism is pressed downward, it can drive the blocking mechanism to rotate, wherein, at the moment when the supporting slide plate 3 impacts upward, the air can be gathered toward the inner wall of the fixed box 33 through the air guide mechanism, and then through the air intake The opening 521 enters into the air storage cavity surrounded by the fixed box 33 and the air guide mechanism. The process of the support slide 3 impacting and sliding upward will be decelerated due to the existence of resistance. After the speed is reduced, the air pressure will lose the pressing force on the pressing mechanism. At this time, the blocking mechanism rotates, and when the support slide 3 rises to the highest point, it will have the force to slide downward. At this time, the air will not impact and gather on the air guide mechanism, and the blocking mechanism rotates one circle at this time, so that the blocking mechanism blocks and seals the air inlet 521 to prevent the gas collected in the air storage cavity from being discharged to the outside. At the same time, the support slide 3 starts to slide downward to complete the process of collecting gas.

[0041] After the gas is collected, the blocking mechanism can block and seal the air inlet 521 to prevent the gas from flowing in and out. The gas flowing into the gas storage cavity contacts the detection mechanism fixedly arranged on the supporting slide plate 3. The gas can be comprehensively detected through the detection mechanism. The detection mechanism can detect the humidity of the air and whether the gas contains toxic gas or sulfur hexafluoride. Once detected, an alarm will be issued immediately to quickly process the surrounding gas.

[0042] Among them, through the forward movement of the inspection vehicle 1, the pulling mechanism can be rotated during the slow movement of the inspection vehicle 1, and the pulling mechanism is in a rotating state during the downward movement. When the pulling mechanism moves downward to a certain range, the supporting slide plate 3 is in a compressed state with respect to the elastic mechanism. When the pulling mechanism is separated from the limit of the supporting slide plate 3, the supporting slide plate 3 has an impact force to impact and slide upward under the action of the elastic force of the elastic mechanism. During the upward impact and sliding process, the air is gathered toward the surrounding of the air guide mechanism through the air guide mechanism and the gas is introduced into the air storage cavity through the air inlet 521. When impacting upward, the air pressure will exert downward pressure on the pressing mechanism. When the supporting slide plate 3 moves upward for a certain distance, it will decelerate. At this time, the pressing force on the pressing mechanism will be reduced. At the same time, the pressing mechanism will drive the blocking mechanism to rotate rapidly, so that the blocking mechanism blocks and seals the air inlet 521 to prevent air from flowing out and in again. At this time, the air can be sealed and comprehensively detected through the detection mechanism, so that the detection environment is in a sealed state to prevent air leakage or inflow during the detection process to prevent affecting the detection of the air. Among them, the support slide plate 3 will slide downward rapidly after moving upward to the highest point, so that the collection and detection of the air can be completed quickly, and the collection and detection process of the inspection vehicle 1 is completed during the movement, so that the collection and detection of the air in a certain area of ​​the substation can be completed quickly.

[0043] Among them, through the up and down sliding setting of the support slide plate 3, the air can be collected during the upward impact and sliding of the support slide plate 3, and the air is collected to the outer edge of the air guide mechanism, and then enters the air storage cavity surrounded by the fixed box 33 and the air guide mechanism through the air inlet 521. In the process of the upward impact and sliding of the support slide plate 3, the air pressure will generate pressure on the pressing mechanism, so that the blocking mechanism rotates, so that the blocking mechanism blocks and seals the air inlet 521, and the collected air is sealed in the air storage cavity for detection, so that the air detection is in a sealed environment to prevent the inflow and outflow of air gas during the air detection process, thereby increasing the accuracy of gas detection.

[0044] like Figure 1 , Figure 2 and Fig.12As shown, a purification exhaust pipe 32 for discharging and purifying the gas in the gas storage cavity is provided on the supporting slide plate 3.

[0045] Among them Fig.12 The position of the purification exhaust pipe 32 can be clearly seen as shown, so that the collected gas can be discharged during exhaust. A purification device for purifying the air is arranged in the purification exhaust pipe 32, and has the effect of exhausting air. The purification device includes a purification filter element and a suction machine. A purification filter element is arranged inside the purification exhaust pipe 32, and the exhausted gas is purified by the purification filter element. A suction machine is arranged at the bottom of the purification exhaust pipe 32 to facilitate gas suction. The gas in the gas storage cavity is purified by the purification filter element and then discharged to the outside. The purification device belongs to the prior art, and the working process is to make the gas pass through the above-described method by sucking the gas. The body is discharged to the outside through the purification filter element, which is not drawn in the figure. The gas drawn into the gas storage cavity is conveniently discharged to the outside in a purified manner through the purification exhaust pipe 32 to prevent affecting the surrounding environment, and the exhaust has the effect of suction, so that when the inspection vehicle 1 moves to another regional detection point, the gas in the gas storage cavity can be completely discharged to prevent affecting the collection and detection of the air again. When the inspection vehicle 1 moves to another regional detection point, the above-mentioned operation is repeated, which will first expose the air inlet 521, and then repeat the operation again to complete the collection and detection of the gas, which can effectively collect and detect the gas in the substation area.

[0046] like Figure 1 As shown, the elastic mechanism includes a damper 11 and a first spring 111 . The damper 11 is fixedly arranged on the top surface of the inspection vehicle 1 . The bottom end of the first spring 111 is fixedly arranged on the damper 11 . The top end of the first spring 111 abuts against the bottom surface of the supporting slide plate 3 .

[0047] Through the setting of the first spring 111, when the supporting slide plate 3 slides downward, a downward pressing force is applied to the first spring 111, so that the first spring 111 is in a compressed state. After being compressed, the first spring 111 has an upward rebound force. Therefore, after the supporting slide plate 3 is out of the limit, the first spring 111 will instantly release the elastic force, and the supporting slide plate 3 will bounce upward quickly. After the supporting slide plate 3 bounces upward and moves to the highest point, it will have an impact force to slide downward, thereby completing the reset.

[0048] Among them, considering that the process of the support slide plate 3 moving downward after moving to the highest point is also fast, there is a possibility of collision and impact with the pulling mechanism, a damper 11 is set at the bottom end of the first spring 111, and the damper 11 can unload the force that hits the first spring 111 and damp the first spring 111, so that the support slide plate 3 slides downward and impacts until it contacts the top of the first spring 111, and then the force can be unloaded under the action of the damper 11, thereby avoiding the support slide plate 3 from bouncing up to a high place again.

[0049] When the support slide plate 3 impacts downward and hits the top of the first spring 111, the first spring 111 will be compressed. However, the first spring 111 can be kept stable by the damping action of the damper 11, and will not be compressed too tight. When the first spring 111 is slowly compressed, the damper 11 will not produce any effect. When the first spring 111 is suddenly compressed with great force, the damper 11 will quickly complete the damping of the first spring 111. This process belongs to the prior art and will not be described in detail. The pressure under the pressure, and under the damping action of the damper 11, can reduce the rebound force of the first spring 111. When the supporting slide plate 3 slides downward to press the first spring 111, the rebound force of the first spring 111 on the supporting slide plate 3 will drop rapidly, and the distance for the supporting slide plate 3 to bounce upward will be reduced. Therefore, at this time, the air pressure is insufficient to press the pressing mechanism, avoiding the rotation of the blocking mechanism and preventing the bottom surface of the supporting slide plate 3 from hitting the pulling mechanism to prevent the air inlet 521 from being exposed, so as to prevent the gas from flowing into or out of the air storage cavity.

[0050] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the pulling mechanism includes a limiting tube 2, an electric telescopic rod 22, a movable plate 23, a pull rod 232, a rotating plate 4 and a second limiting slider 41. The limiting tube 2 is fixedly connected to the inspection vehicle 1, and the movable plate 23 is slidably arranged on the inner wall of the limiting tube 2. The electric telescopic rod 22 is arranged between the bottom end of the inner wall of the limiting tube 2 and the movable plate 23. The top of the electric telescopic rod 22 is rotatably connected to the movable plate 23, and the pull rod 232 is fixedly arranged on the top of the movable plate 23. The outer periphery of the movable plate 23 is fixedly provided with a first limiting slider 231. The inner wall of the limiting tube 2 is provided with a rotating groove 21 for the first limiting slider 231 to slide, and the rotating groove 21 is arranged around the inner wall of the limiting tube 2. The top of the pull rod 232 is fixedly connected to one side of the bottom surface of the rotating plate 4, and the second limiting slider 41 is fixedly connected to the top surface of the rotating plate 4. The second limiting slider 41 is in a cross-shaped structure, and the bottom surface of the supporting slide plate 3 is provided with a limiting groove 31 for the second limiting slider 41 to rotate and slide.

[0051] The activation of the electric telescopic rod 22 can drive the movable plate 23 to move downward, and the movable plate 23 drives the pull rod 232 to move downward, and the movable plate 23 drives the first limit slider 231 to slide in the rotary groove 21. Through the surrounding arrangement of the rotary groove 21, when the movable plate 23 moves downward, the movable plate 23 can be in a state of rotating downward movement, thereby driving the pull rod 232 to rotate downward, and the pull rod 232 drives the rotating plate 4 to rotate downward, wherein the pull rod 232 is fixedly arranged on one side of the bottom surface of the rotating plate 4, such as Figure 1 and Figure 3It can be seen that the state diagram of the rotating plate 4 and the pull rod 232 shows that when the rotating plate 4 is in the rotating state, it rotates through the pull rod 232 as the axis, and Figure 2 The state of the limit slot 31 can be seen in the figure, and the openings on both sides thereof penetrate the supporting slide plate 3. When the rotating plate 4 slides on the bottom surface of the supporting slide plate 3, it is convenient to slide the second limit slider 41 into the limit slot 31, and with the rotation of the rotating plate 4, the second limit slider 41 can slide out of the limit slot 31, and the second limit slider 41 is in the process of rotating downward. Therefore, when the second limit slider 41 slides out of the limit slot 31, the first spring 111 will instantly release the elastic force, so that the supporting slide plate 3 has an upward impact sliding force. When the supporting slide plate 3 moves to the bottom end, the electric telescopic rod 22 is started and drives the rotating plate 4 to rotate and move upward, and can make the rotating plate 4 rotate the second limit slider 41 into the limit slot 31 during the rotation and upward process, so as to ensure that when the supporting slide plate 3 is launched again, the supporting slide plate 3 makes an upward impact slide.

[0052] Among them, considering the situation that the second limit slider 41 can rotate into the limit groove 31, it is necessary to start the electric telescopic rod 22 to rotate the rotating plate 4 upward after the contact area between the bottom surface of the supporting slide plate 3 and the first spring 111 is stable, and the two ends of the limit groove 31 are both arc-shaped structures, so that the second limit slider 41 can smoothly rotate into the limit groove 31.

[0053] like Figure 1 , Figure 6 and Figure 7 As shown, the air guide mechanism includes an air guide plate 5 with an arc-shaped structure, a sleeve 51 and a ring 52. The ring 52 is fixedly arranged on the inner wall of the fixed box 33, and the inner wall of the ring 52 is fixedly arranged on the periphery of the air guide plate 5. The air inlet 521 is evenly opened on both sides of the sleeve 52. The sleeve 51 is fixedly arranged on the top of the air guide plate 5, and the bottom end of the sleeve 51 passes through the air guide plate 5.

[0054] The blocking mechanism includes a connecting ring 611 and a baffle 612 . The connecting ring 611 is rotatably arranged on the bottom surface of the air guide plate 5 . The baffle 612 is fan-shaped and fixedly arranged on both sides of the outer periphery of the connecting ring 611 . The baffle 612 is arranged corresponding to the air inlet 521 .

[0055] By setting the arc structure of the air guide plate 5, as Figure 7 It can be seen that the air guide plate 5 is in an arc state. When the supporting slide plate 3 impacts and slides upward, the air will impact the air guide plate 5. At this time, the arc structure of the air guide plate 5 is used to guide the air toward the periphery of the air guide plate 5, so that the air enters from the air inlet 521. A connecting ring 611 is rotatably provided on the bottom surface of the air guide plate 5, and a baffle 612 is provided on the periphery of the connecting ring 611. The baffle 612 is provided corresponding to the air inlet 521. The baffle 612 can be rotated to the bottom of the air inlet 521 to block and seal the air inlet 521.

[0056] like Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.13 As shown, the pressing mechanism is sleeved in the sleeve 51, and the pressing mechanism includes a rotating rod 6, a fixed plate 62, a third spring 63, a convex tube 64, a rotating tube 65, a limiting support rod 66, a pressing tube 7 and a pressing rod 71. The fixing plate 62 is fixedly arranged on the inner wall of the sleeve 51 near the bottom end, the rotating rod 6 and the fixing plate 62 are rotatably connected through a bearing, and a connecting plate 61 is fixedly connected between the outer periphery of the bottom end of the rotating rod 6 and the connecting ring 611, the rotating tube 65 is slidably sleeved on the outer periphery of the rotating rod 6, and a linkage positioning rod 67 is fixedly arranged on the outer periphery of the rotating rod 6. A limiting guide hole for the linkage positioning rod 67 to slide is opened on the inner wall of the rotating tube 65, and the pressing tube 7 is crimped on the top of the rotating tube 65. The outer periphery of the pressing tube 7 is slidably sleeved on the sleeve 5 1 inner wall, the top of the inner wall of the pressing tube 7 is fixedly connected with the pressing rod 71, the bottom of the pressing tube 7 is provided with a guide groove 72 in a triangular structure, and the outer periphery of the top of the rotating tube 65 is provided with an inclined groove 651 corresponding to the guide groove 72, the top of the rotating rod 6 is inserted into the pressing tube 7, and the top of the rotating rod 6 is located in the pressing tube 7 and does not contact the inner wall of the pressing tube 7 to prevent the rotation of the rotating rod 6 from being affected, and a limiting support rod 66 is fixedly provided on the outer periphery of the top of the rotating rod 6, and a sliding groove 652 for sliding the limiting support rod 66 is provided on the outer periphery of the pressing tube 7 and the rotating tube 65, the convex tube 64 is rotatably arranged at the bottom of the rotating tube 65, the third spring 63 is fixedly arranged between the convex tube 64 and the fixed plate 62, and the third spring 63 is sleeved on the outer periphery of the rotating rod 6.

[0057] By pressing the pressing rod 71, the pressing tube 7 can be pressed downward, and the pressing tube 7 presses the rotating tube 65 downward, so that the rotating tube 65 slides up and down on the periphery of the rotating rod 6 under the limiting action of the linkage positioning rod 67. At this time, the rotating tube 65 presses the convex tube 64 and the third spring 63 downward, so that the limiting support rod 66 slides in the sliding groove 652, wherein the pressing of the third spring 63 will generate an elastic force, and the elastic force has a reaction force, thereby causing the third spring 63 to press the rotating tube 65 upward, and the pressing force on the pressing tube 7 causes the limiting support rod 66 to move upward relative to the rotating tube 65. When the bottom end of the positioning support rod 66 moves to the top position of the inclined slot 651, the bottom end of the limiting support rod 66 will contact the top of the inclined slot 651. At this time, since the inclined slot 651 is in an inclined state and the pressing tube 7 loses the pressing force or the pressing force becomes smaller, the limiting support rod 66 will slide along the inclined surface of the inclined slot 651. During the sliding process of the limiting support rod 66 along the inclined surface of the inclined slot 651, it will press the rotating tube 65, so that the rotating tube 65 rotates ninety degrees. At this time, the rotating tube 65 drives the linkage positioning rod 67 to rotate, thereby driving the rotating rod 6 to rotate ninety degrees. Figure 8 , Fig.10 , Fig.11 and Fig.13The diagram shown clearly shows the status of the rotating tube 65 and the pressing tube 7. The principle described above can be realized by pressing the pressing tube 7, so that after the pressing tube 7 is subjected to pressure and the bottom end of the limiting support rod 66 reaches the top of the inclined groove 651, the rotating tube 65 can be rotated ninety degrees. The rotation of the rotating tube 65 can drive the rotating rod 6 to rotate ninety degrees through the linkage positioning rod 67, and the rotating rod 6 drives the connecting plate 61 to rotate, so that the connecting plate 61 drives the connecting ring 611 to rotate ninety degrees, and then the baffle 612 rotates ninety degrees, completing the intermittent blocking seal of the air inlet 521.

[0058] Additional note: Figure 8 The position of the slide groove 652 can be seen in the figure. When in a stationary state, the slide groove 652 provided on the pressing tube 7 and the slide groove 652 provided on the rotating tube 65 are in a connected state, and when the limiting support rod 66 is in a sliding state on the inclined groove 651, the rotating tube 65 is in a rotating state relative to the pressing tube 7. At this time, the bottom end of the pressing tube 7 at the bottom end of the guide groove 72 will slide on the inclined groove 651. Once the bottom end of the pressing tube 7 slides on the inclined groove 651, the slide groove 652 provided on the rotating tube 65 will be in a connected state with the inclined groove 651. Therefore, when the pressing tube 7 is pressed, the rotating tube 65 can complete a ninety-degree rotation.

[0059] Among them, Fig.13 The state of the linkage positioning rod 67 is shown in the figure. Through the setting of the linkage positioning rod 67, when the rotating tube 65 is pressed, it will first slide around the rotating rod 6. Under the limiting action of the linkage positioning rod 67, the up and down sliding effect of the rotating tube 65 can be guaranteed, and when the limiting support rod 66 slides in the inclined groove 651, the rotating tube 65 can rotate. At this time, the rotating tube 65 pulls the linkage positioning rod 67 to be in a rotating state, and the linkage positioning rod 67 is fixedly set on the periphery of the rotating rod 6, so the rotation of the rotating tube 65 can drive the rotating rod 6 to rotate.

[0060] Among them, the principle of downward pressing and rotating is mainly through pressing the pressure rod 71 and the pressure tube 7. The above has described the overall process of pressing and rotating, and no further elaboration is made. Therefore, by supporting the upward impact sliding of the sliding plate 3, the pressure on the pressure rod 71 can be completed through air pressure to ensure that the baffle 612 is in a state of intermittently blocking the air inlet 521.

[0061] like Fig.12 As shown, the detection mechanism includes a detection plate 34 , which is fixedly disposed on the top surface of the supporting slide plate 3 and sleeved in the fixing box 33 .

[0062] By setting up the detection board 34, comprehensive detection of gas can be carried out, including: humidity detection, toxic gas detection, sulfur hexafluoride gas detection, etc., to ensure the good state of the environment around the substation to prevent affecting the normal operation of the equipment in the substation.

[0063] Example 2

[0064] Please refer to Fig.14 As shown, other parts of this embodiment are the same as those of the embodiment 1, and the difference lies in that the limiting sliding rod 12 is set as a tubular structure.

[0065] A second spring 121 is sleeved on the outer periphery of the limit slide bar 12 near the top, and the tops of the multiple limit slide bars 12 are sequentially provided with an air intake component with multi-angle adjustment of the air intake direction, a multi-angle adjustment of the monitoring component, a temperature sensor component for real-time monitoring of the external temperature, and a buzzer alarm component. A gas storage tank is detachably arranged below the corresponding air intake component on the inspection vehicle 1, and power supply equipment is arranged below the corresponding monitoring component, temperature sensor component and buzzer alarm component on the inspection vehicle 1.

[0066] Through the setting of the air suction component, when the gas is detected to be toxic or contains sulfur hexafluoride gas, the air suction component can be used to absorb the outside air, and the absorbed gas can be stored in the gas tank to process the outside air to avoid large-scale diffusion. The power supply equipment can provide power to the monitoring component, temperature sensor component and buzzer alarm component to facilitate continuous operation. The multi-angle adjustable monitoring component can monitor the status of the substation in real time, and the temperature sensor component can detect the temperature in the substation environment in real time. Through the setting of the buzzer alarm component, when a problem is detected in the environment, the buzzer alarm can be issued in time to remind the staff to deal with it in time.

[0067] Among them, the monitoring equipment can adopt the camera used for road administration monitoring, and the angle of the camera can be adjusted for multi-directional monitoring. The air intake component can adopt the dust removal equipment in the workshop, which absorbs the gas to avoid large-scale diffusion. The temperature sensing component can adopt the temperature and humidity sensor, which uses the temperature and humidity sensor to monitor the temperature and humidity of the external air.

[0068] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
