[0007] Preferably, a slow exhaust valve is fixedly connected to the top of the second piston cylinder, a visual inspection device is fixedly connected to the top of the second piston plate, and a connecting line is fixedly connected to the bottom of the visual inspection device.

[0008] Preferably, the moving rod is fitted to the inner wall of the piston cylinder 1, and the top end of the piston cylinder 1 is fixedly connected with a one-way air intake valve.

[0009] Preferably, the spring assembly 1 and the spring assembly 2 are both composed of a damping telescopic rod and a spring, and the damping telescopic rod is located at the center of the spring inner cavity.

[0010] Preferably, both the front and rear sides of the inclined lifting block are inclined surfaces, and the rotating wheel fits with the inclined surfaces of the inclined lifting block.

[0011] Preferably, the air outlet pipe is movably sleeved in the inner cavity of the T-shaped connecting pipe, and the air outlet pipe is connected with the inner cavity of the second piston cylinder through the T-shaped connecting pipe.

[0012] Preferably, a downward pressure hole is opened at the bottom end of the second piston cylinder, and the middle part of the inclined lifting block is located below the pressing rod.

[0013] Preferably, the top end of the one-way air inlet valve is fixedly connected to a connecting pipe, the bottom end of the connecting pipe is fixedly connected to a telescopic tube, the bottom end of the telescopic tube is fixedly connected to a mounting tube, the mounting tube is fixedly connected to a blowing nozzle on the side close to the moving wheel, the side of the moving rod away from the inspection mobile vehicle is fixedly connected to a fixing rod, the side of the fixing rod close to the moving wheel is fixedly connected to a scraping rod, and the scraping rod is in contact with the surface of the moving wheel.

[0014] An inspection method for an urban and rural underground pipe network inspection device, starting a driving motor to drive a moving wheel to rotate, thereby driving an inspection mobile vehicle and a visual inspection device to move, then inspecting the underground pipe network through the visual inspection device, and then transmitting data or images to the inspection mobile vehicle through a connecting line;

[0015] When passing through a rough road, due to the elasticity of the return spring 1, the moving wheel will move when passing through the rough road, thereby driving the moving rod to rise and fall in the inner cavity of the piston cylinder 1. When the moving rod moves upward in the inner cavity of the piston cylinder 1, the air in the inner cavity of the piston cylinder 1 will be input into the T-shaped connecting pipe through the one-way air outlet valve along the air outlet pipe. When the moving rod moves downward, the external air will be drawn into the inner cavity of the piston cylinder 1 through the one-way air inlet valve. The air entering the inner cavity of the T-shaped connecting pipe is then input into the inner cavity of the piston cylinder 2, thereby squeezing the piston plate 2, thereby driving the piston plate 2 to move downward;

[0016] When the vehicle needs to pass through a rough road in a short time, the amount of air entering the inner cavity of the piston cylinder 2 from the piston cylinder 1 is small, so that the air in the inner cavity of the piston cylinder 2 is slowly discharged through the slow exhaust valve, and the piston plate 2 is reset by the tension of the reset spring 2 after it drops a short distance;

[0017] When on a rough road for a long time, the moving wheel moves back and forth, squeezing a large amount of air into the inner cavity of the second piston cylinder, thereby driving the pressing rod at the bottom end of the second piston plate to pass through the downward pressure hole to press the inclined lifting block, so that the inclined lifting block moves downward. When the inclined lifting block moves downward, it drives the rotating wheel to move, and then drives the moving plate to move to both sides of the inspection mobile vehicle, thereby changing the interval between the two moving plates, and then moving the moving wheel. After the interval between the moving wheels is increased, the area of ​​the bottom center of gravity is increased, thereby preventing the inspection mobile vehicle from tipping over when passing through a rough road;

[0018] When the second piston plate moves downward, the visual inspection device is driven downward, thereby lowering the overall center of gravity and further improving the stability during movement;

[0019] When the moving rod squeezes the air in the inner cavity of the piston cylinder, the squeezed air enters the inner cavity of the connecting pipe along the one-way air inlet valve, and then enters the inner cavity of the mounting pipe through the telescopic tube, and is blown out to the surface of the moving wheel through the blowing nozzle to remove dust, and then the foreign matter contaminated on the outer surface of the moving wheel is scraped off by the scraping rod, and when the moving rod is raised or lowered, the blowing nozzle and the scraping rod can be driven to rise or fall.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The present invention starts a driving motor to drive the moving wheel to rotate, and the rotation of the moving wheel drives the inspection mobile vehicle to move. When the inspection mobile vehicle passes through a rough road surface, due to the retractability and elasticity of the reset spring 1, the moving rod can be raised and lowered in the inner cavity of the piston cylinder 1, so that when the moving wheel passes through the rough road surface, the setting of the reset spring 1 and the air pressure in the inner cavity of the piston cylinder 1 are used to reduce the shock of the moving wheel, thereby avoiding high-frequency and high-amplitude vibrations of the inspection mobile vehicle, which may cause the visual inspection equipment and the components inside the inspection mobile vehicle to become loose or damaged.

[0022] 2. In the present invention, the air entering the inner cavity of the second piston cylinder is slowly discharged through the slow exhaust valve, and then the air in the inner cavity of the first piston cylinder enters the inner cavity of the second piston cylinder along the T-shaped connecting pipe, driving the second piston plate to move downward, thereby driving the visual inspection equipment to move downward, thereby reducing the height of the visual inspection equipment. During normal road inspections, in order to ensure that the underground pipeline network can be inspected in an all-round manner and the inspection is accurate, the height of the visual inspection equipment is relatively high, thereby allowing a wider inspection range. When passing through rugged roads, the height of the visual inspection equipment is reduced, thereby avoiding the overall high center of gravity and the large swing amplitude of the visual inspection equipment, which may cause the second piston plate to break or the internal components of the visual inspection equipment to be damaged.

[0023] 3. The present invention increases the range of the bottom center of gravity by changing the interval between the moving wheels, so that the inspection mobile vehicle will not roll over when passing through a rough road surface, thereby improving the stability of the inspection mobile vehicle when passing through a rough road surface. In addition, since the center of gravity area is only increased on the rough road surface, it will not cause a larger volume when passing through a normal road surface, and will not cause a larger volume when parked, affecting the parking space.

[0024] 4. The present invention allows the air in the inner cavity of the moving rod to be blown out from the one-way air inlet valve and blown along the blowing nozzle to remove the dust on the surface of the moving wheel and the scraping rod to scrape off the foreign matter on the surface of the moving wheel, thereby ensuring that the surface of the moving wheel remains clean, avoiding the surface being contaminated with a lot of foreign matter that affects the movement speed and the foreign matter being brought to the parking place of the inspection equipment, thereby affecting the sanitary environment of the parking place.

[0034] 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.

[0035] like Figures 1 to 8 As shown, an embodiment of the present invention provides an urban and rural underground pipe network inspection device, including an inspection mobile vehicle 1, the inner cavity of the bottom of the inspection mobile vehicle 1 is fixedly connected to a spring component 2, the side of the spring component 2 away from the inspection mobile vehicle 1 is fixedly connected to a moving plate 3, both ends of the moving plate 3 away from the spring component 2 are fixedly connected to a piston cylinder 4, the inner cavity of the piston cylinder 4 is fixedly connected to a return spring 5, the bottom end of the return spring 5 is fixedly connected to a moving rod 6, the bottom end of the moving rod 6 is fixedly connected to a driving motor 7, and the output end of the driving motor 7 is fixedly connected to a moving wheel 8;

[0036] The working principle and beneficial effects of the above technical solution are as follows: by starting the driving motor 7 to drive the moving wheel 8 to rotate, the rotation of the moving wheel 8 drives the inspection mobile vehicle 1 to move. When the inspection mobile vehicle 1 passes through a rough road surface, due to the retractability and elasticity of the reset spring 5, the moving rod 6 can be raised and lowered in the inner cavity of the piston cylinder 4, so that when the moving wheel 8 passes through the rough road surface, the setting of the reset spring 5 and the air pressure in the inner cavity of the piston cylinder 4 can reduce the shock of the moving wheel 8, thereby avoiding the inspection mobile vehicle 1 from vibrating at a high frequency and a high amplitude, which may cause the visual inspection equipment 18 and the components inside the inspection mobile vehicle 1 to become loose or damaged.

[0037] like Figure 2As shown, in one embodiment, the top of the piston cylinder 1 4 is fixedly connected with a one-way air outlet valve 9, the top of the one-way air outlet valve 9 is fixedly connected with an air outlet pipe 10, the middle of the inner cavity of the inspection mobile vehicle 1 is fixedly connected with a piston cylinder 2 12, the top of the piston cylinder 2 12 is fixedly connected with a T-shaped connecting pipe 13, the inner cavity of the piston cylinder 2 12 is fixedly connected with a reset spring 2 15, the top of the reset spring 2 15 is fixedly connected with a piston plate 2 16, the bottom end of the piston plate 2 16 is fixedly connected to a pressing rod 19, the inner cavity of the inspection mobile vehicle 1 is fixedly connected with a spring assembly 20, the bottom end of the spring assembly 20 is fixedly connected with an inclined lifting block 21, the middle part of the moving plate 3 is fixedly connected to a side close to the inclined lifting block 21, and the inner cavity of the mounting frame 22 is movably connected with a rotating wheel 23;

[0038] The working principle and beneficial effects of the above technical solution are as follows: when the inspection mobile vehicle 1 passes through a long and rough road, the moving rod 6 reciprocates for a long time in the inner cavity of the piston cylinder 1 4, thereby squeezing more air into the inner cavity of the T-shaped connecting pipe 13 through the one-way air outlet valve 9 and the air outlet pipe 10, and the air enters the inner cavity of the piston cylinder 2 12 along the T-shaped connecting pipe 13, thereby driving the piston plate 2 16 to descend;

[0039] Since there are more air cells entering the piston cylinder 12 and the slow air outlet valve 14 discharges air at a slower speed, a large amount of air in the inner cavity of the piston cylinder 12 presses the piston plate 16. After the piston plate 16 is pressed downward, it drives the pressing rod 19 to pass through the downward pressure hole 24 to press the inclined lifting block 21, thereby driving the inclined lifting block 21 to descend. When the inclined lifting block 21 descends, it drives the rotating wheel 23 in contact with it to move, thereby driving the mounting frame 22 to move, and then driving the moving plate 3 to move, thereby changing the interval of the moving plate 3, and then changing the interval of the moving wheels 8, thereby increasing the range of the bottom center of gravity, so that the inspection mobile vehicle 1 will not roll over when passing through a rugged road surface or a road surface with a large inclination.

[0040] like Figure 4 As shown, in one embodiment, the top of the second piston cylinder 12 is fixedly connected with a slow exhaust valve 14, the top of the second piston plate 16 is fixedly connected with a visual inspection device 18, and the bottom of the visual inspection device 18 is fixedly connected with a connecting line 17;

[0041] The working principle and beneficial effects of the above technical solution are as follows: the air entering the inner cavity of the piston cylinder 12 will be slowly discharged through the slow exhaust valve 14, and then the air in the inner cavity of the piston cylinder 14 will enter the inner cavity of the piston cylinder 12 along the T-shaped connecting pipe 13, driving the piston plate 16 to move downward, thereby driving the visual inspection equipment 18 to move downward, thereby reducing the height of the visual inspection equipment 18.

[0042] like Figure 3As shown, in one embodiment, the moving rod 6 is attached to the inner wall of the piston cylinder 4, and the top end of the piston cylinder 4 is fixedly connected with a one-way air intake valve 11;

[0043] The working principle and beneficial effects of the above technical solution are as follows: by moving the rod 6 in contact with the inner wall of the piston cylinder 4, the moving rod 6 can squeeze the air in the inner cavity of the piston cylinder 4 when the inner cavity of the piston cylinder 4 is raised or lowered, and by setting the one-way air intake valve 11, the moving rod 6 can draw external air into the inner cavity of the piston cylinder 4 through the one-way air intake valve 11 when the inner cavity of the piston cylinder 4 is lowered, so as to replenish the air in the inner cavity of the piston cylinder 4.

[0044] like Figure 2 As shown, in one embodiment, the spring assembly 1 2 and the spring assembly 2 20 are both composed of a damping telescopic rod and a spring, and the damping telescopic rod is located at the center of the spring cavity;

[0045] The working principle and beneficial effects of the above technical solution are as follows: when the inspection mobile vehicle 1 passes through a rough road surface, the air in the inner cavity of the piston cylinder 12 is slowly discharged from the slow exhaust valve 14, and then the springs of the spring assembly 1 2 and the spring assembly 20 drive the moving plate 3 and the inclined lifting block 21 to reset, and then the moving plate 3 and the inclined lifting block 21 are positioned and guided by the damping telescopic rod, thereby avoiding the displacement of the moving plate 3 and the inclined lifting block 21 during the resetting process, thereby improving its stability during resetting.

[0046] like Figure 3 As shown, in one embodiment, both the front and rear sides of the inclined lifting block 21 are inclined surfaces, and the rotating wheel 23 fits with the inclined surface of the inclined lifting block 21;

[0047] The working principle and beneficial effects of the above technical solution are as follows: the inclined surfaces on the front and rear sides of the inclined lifting block 21 are fitted with the rotating wheel 23, so that when the inclined lifting block 21 is pressed down by the pressing rod 19, the inclined surface of the inclined lifting block 21 is driven to move downward, thereby driving the rotating wheel 23 fitted therewith to move, and the movement of the rotating wheel 23 drives the moving plate 3 to move, thereby changing the interval of the moving plate 3.

[0048] like Figure 3 As shown, in one embodiment, the air outlet pipe 10 is movably sleeved in the inner cavity of the T-shaped connecting pipe 13, and the air outlet pipe 10 is connected with the inner cavity of the piston cylinder 12 through the T-shaped connecting pipe 13;

[0049] The working principle and beneficial effects of the above technical solution are as follows: the air outlet pipe 10 is movably sleeved in the inner cavity of the T-shaped connecting pipe 13, so that when the moving wheel 8 is separated to drive the air outlet pipe 10 to move, the air outlet pipe 10 can move in the inner cavity of the T-shaped connecting pipe 13, and no air leakage will occur, so that when the moving wheel 8 moves, the air in the inner cavity of the piston cylinder 12 can be stably discharged only from the slow outlet valve 14.

[0050] like Figure 4 As shown, in one embodiment, a lower pressure hole 24 is provided at the bottom end of the piston cylinder 12, and the middle part of the inclined lifting block 21 is located below the pressing rod 19;

[0051] The working principle and beneficial effects of the above technical solution are as follows: through the downward pressure hole 24 at the bottom end of the piston cylinder 12, the piston plate 16 can drive the pressing rod 19 to press the inclined lifting block 21 when the downward movement distance is long, and through the setting of the pressing rod 19, when passing through a rough road for a short time, the pressing rod 19 will not press the inclined lifting block 21 downward. Only when passing through the rough road for a long time, more air enters the inner cavity of the piston cylinder 12, causing the pressing rod 19 to move downward through the downward pressure hole 24 to press the inclined lifting block 21, and the moving wheel 8 will expand the spacing to increase the bottom center area.

[0052] like Figure 7 As shown, in one embodiment, the top end of the one-way air inlet valve 11 is fixedly connected to a connecting pipe 25, the bottom end of the connecting pipe 25 is fixedly connected to a telescopic pipe 26, the bottom end of the telescopic pipe 26 is fixedly connected to a mounting pipe 27, the side of the mounting pipe 27 close to the moving wheel 8 is fixedly connected to a blowing nozzle 28, the side of the moving rod 6 away from the inspection mobile vehicle 1 is fixedly connected to a fixing rod 29, the side of the fixing rod 29 close to the moving wheel 8 is fixedly connected to a scraping rod 30, and the scraping rod 30 is in contact with the surface of the moving wheel 8;

[0053] The working principle and beneficial effects of the above technical scheme are as follows: when the air in the inner cavity of the piston cylinder 4 is squeezed by the moving rod 6, the squeezed air will be output through the one-way air inlet valve 11, enter the inner cavity of the connecting pipe 25, and be transported to the inner cavity of the mounting pipe 27 along the connecting pipe 25 and the telescopic pipe 26, and then blown out to the surface of the moving wheel 8 through the blowing nozzle 28, so as to blow away the dust and debris on the surface of the moving wheel 8, and then the mud or other foreign matter adhered to the outer surface of the moving wheel 8 is scraped off by the scraper rod 30, and the connection between the fixed rod 29 and the moving rod 6 makes the moving wheel 8 drive the moving rod 6 to rise and fall when passing through a rugged road, and then drive the mounting pipe 27 and the scraper rod 30 to rise and fall, thereby ensuring that the surface of the moving wheel 8 remains clean, avoiding the situation where the surface is contaminated with a lot of foreign matter that affects the movement speed and these foreign matter are brought to the parking place of the inspection equipment, affecting the sanitary environment of the parking place.

[0054] like Figures 1 to 6 As shown, the embodiment of the present invention provides an inspection method for an urban and rural underground pipe network inspection device, wherein the driving motor 7 is started to drive the moving wheel 8 to rotate, thereby driving the inspection mobile vehicle 1 and the visual inspection device 18 to move, and then the underground pipe network is inspected by the visual inspection device 18, and then the data or picture is transmitted to the inspection mobile vehicle 1 through the connecting line 17;

[0055] When passing through a rough road, due to the elasticity of the return spring 15, the moving wheel 8 will move when passing through the rough road, thereby driving the moving rod 6 to rise and fall in the inner cavity of the piston cylinder 14. When the moving rod 6 moves upward in the inner cavity of the piston cylinder 14, the air in the inner cavity of the piston cylinder 14 will be input into the T-shaped connecting pipe 13 through the one-way air outlet valve 9 along the air outlet pipe 10. When the moving rod 6 moves downward, the external air will be drawn into the inner cavity of the piston cylinder 14 through the one-way air inlet valve 11. The air entering the inner cavity of the T-shaped connecting pipe 13 is then input into the inner cavity of the piston cylinder 12, thereby squeezing the piston plate 16, and then driving the piston plate 16 to move downward;

[0056] When the rough road surface can be passed in a short time, the amount of air entering the inner cavity of the piston cylinder 12 from the piston cylinder 1 is small, so that the air in the inner cavity of the piston cylinder 12 is slowly discharged through the slow air outlet valve 14, and the piston plate 16 is reset by the tension of the reset spring 15 after it drops a short distance;

[0057] When on a rough road for a long time, the moving wheel 8 moves back and forth, squeezing a large amount of air into the inner cavity of the piston cylinder 12, thereby driving the pressing rod 19 at the bottom end of the piston plate 16 to pass through the lower pressure hole 24 to press the inclined lifting block 21, so that the inclined lifting block 21 moves downward. When the inclined lifting block 21 moves downward, it drives the rotating wheel 23 to move, and then drives the moving plate 3 to move to both sides of the inspection mobile vehicle 1, thereby changing the interval between the two moving plates 3, and then moving the moving wheel 8. After the interval between the moving wheels 8 is increased, the area of ​​the bottom center of gravity is increased, thereby preventing the inspection mobile vehicle 1 from tipping over when passing through a rough road;

[0058] When the piston plate 16 moves downward, the visual inspection device 18 is driven downward, thereby lowering the overall center of gravity and further improving the stability during movement; and when the moving rod 6 squeezes the air in the inner cavity of the piston cylinder 4, the squeezed air enters the inner cavity of the connecting pipe 25 along the one-way air intake valve 11, and then enters the inner cavity of the mounting pipe 27 through the telescopic tube 26, and is blown out to the surface of the moving wheel 8 through the blowing nozzle 28 to remove dust, and then the foreign matter contaminated on the outer surface of the moving wheel 8 is scraped off by the scraping rod 30, and when the moving rod 6 is raised or lowered, it can drive the blowing nozzle 28 and the scraping rod 30 to rise or fall.

The urban and rural underground pipe network inspection device according to claim 2, characterized in that: A downward pressure hole (24) is provided at the bottom end of the second piston cylinder (12), and the middle part of the inclined lifting block (21) is located below the pressing rod (19).

9. The urban and rural underground pipe network inspection device according to claim 2, characterized in that: The top end of the one-way air inlet valve (11) is fixedly connected to a connecting pipe (25), the bottom end of the connecting pipe (25) is fixedly connected to a telescopic pipe (26), the bottom end of the telescopic pipe (26) is fixedly connected to a mounting pipe (27), the side of the mounting pipe (27) close to the moving wheel (8) is fixedly connected to a blowing nozzle (28), the side of the moving rod (6) away from the inspection moving vehicle (1) is fixedly connected to a fixing rod (29), the side of the fixing rod (29) close to the moving wheel (8) is fixedly connected to a scraping rod (30), and the scraping rod (30) is in contact with the surface of the moving wheel (8).

10. A method for inspecting an urban and rural underground pipe network inspection device, characterized in that: The urban and rural underground pipe network inspection device according to any one of claims 1 to 9 is used, and the steps are as follows: starting the driving motor (7) to drive the moving wheel (8) to rotate, thereby driving the inspection mobile vehicle (1) and the visual inspection device (18) to move, then inspecting the underground pipe network through the visual inspection device (18), and then transmitting the data or pictures to the inspection mobile vehicle (1) through the connecting line (17); When passing through a rough road surface, due to the elasticity of the return spring 1 (5), the moving wheel (8) will move when passing through the rough road surface, thereby driving the moving rod (6) to rise and fall in the inner cavity of the piston cylinder 1 (4). When the moving rod (6) moves upward in the inner cavity of the piston cylinder 1 (4), the air in the inner cavity of the piston cylinder 1 (4) will be input into the T-shaped connecting pipe (13) through the one-way air outlet valve (9) along the air outlet pipe (10). When the moving rod (6) moves downward, the external air is sucked into the inner cavity of the piston cylinder 1 (4) through the one-way air inlet valve (11). The air entering the inner cavity of the T-shaped connecting pipe (13) is then input into the inner cavity of the piston cylinder 2 (12), thereby squeezing the piston plate 2 (16), thereby driving the piston plate 2 (16) to move downward; When the vehicle needs to pass through a rough road surface in a short time, the amount of air entering the inner cavity of the second piston cylinder (12) from the first piston cylinder (4) is small, so that the air in the inner cavity of the second piston cylinder (12) is slowly discharged through the slow air outlet valve (14), and the second piston plate (16) can be reset by the tension of the second reset spring (15) after it drops a short distance; When on a rough road for a long time, the moving wheel (8) moves back and forth, squeezing a large amount of air into the inner cavity of the second piston cylinder (12), thereby driving the pressing rod (19) at the bottom end of the second piston plate (16) to pass through the downward pressure hole (24) to press the inclined lifting block (21), so that the inclined lifting block (21) moves downward. When the inclined lifting block (21) moves downward, it drives the rotating wheel (23) to move, and then drives the moving plate (3) to move to both sides of the inspection mobile vehicle (1), thereby changing the interval between the two moving plates (3), and then moving the moving wheel (8). After the interval between the moving wheels (8) increases, the area of ​​the bottom center of gravity is increased, thereby preventing the inspection mobile vehicle (1) from tipping over when passing through a rough road; When the second piston plate (16) moves downward, the visual inspection device (18) is driven downward, thereby lowering the center of gravity of the whole, further improving the stability during movement; When the moving rod (6) squeezes the air in the inner cavity of the piston cylinder (4), the squeezed air enters the inner cavity of the connecting pipe (25) along the one-way air inlet valve (11), and then enters the inner cavity of the mounting pipe (27) through the telescopic pipe (26), and is blown out to the surface of the moving wheel (8) through the blowing nozzle (28) to remove dust from it, and then the foreign matter contaminated on the outer surface of the moving wheel (8) is scraped off by the scraping rod (30), and when the moving rod (6) is raised or lowered, the blowing nozzle (28) and the scraping rod (30) can be driven to rise or fall.
