Description

Technical Field

[0001] The utility model relates to the technical field of harmful gas monitoring, in particular to a walking mechanism of a harmful gas monitoring robot in a limited space. Background Art

[0002] With the acceleration of industrialization, the safety issues in confined spaces have become increasingly prominent. In these spaces, the accumulation of harmful gases may cause serious harm to human health and even cause major accidents such as explosions and fires. Therefore, real-time monitoring and early warning of harmful gases in confined spaces are particularly important.

[0003] By integrating a gas sensing system, a video surveillance system, a voice communication system, and an intelligent analysis algorithm, the harmful gas monitoring robot can achieve real-time monitoring of oxygen concentration, flammable and explosive substances, and toxic and harmful gas concentrations in a confined space. However, due to the limited space of the harmful gas monitoring robot's detection location, the monitoring robot is usually small in size and light in weight. When the monitoring robot moves on uneven ground, it may cause the monitoring robot to tilt, which may affect the detection of the monitoring robot.

[0004] In order to solve the above problems, this application proposes a walking mechanism of a confined space harmful gas monitoring robot. Utility Model Content

[0005] The utility model aims to solve the technical problems existing in the prior art and provides a walking mechanism of a harmful gas monitoring robot in a confined space.

[0006] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: a walking mechanism of a harmful gas monitoring robot in a confined space, including a robot body, the robot body is provided with an anti-rollover structure, the anti-rollover structure includes a water tank fixedly connected to the robot body, the outer wall of the water tank is fixedly connected to a circular tube, the interior of the circular tube is slidably connected to a support rod, the inner wall of the water tank is fixedly connected to a water collecting pipe, the inner wall of the water collecting pipe is fixedly connected to a first spring, one end of the first spring is fixedly connected to a push block, a connecting plate is rotatably connected to the robot body, the top of the connecting plate is hinged with a circular rod, the outer wall of the circular rod is fixedly connected to a second spring, one end of the second spring is fixedly connected to the robot body, the circular rod is slidably connected to the circular tube, the connecting plate and the end away from the circular rod are hinged with a top plate, the top of the top plate is fixedly connected to a fixing ring, and the fixing ring is slidably connected to the circular tube.

[0007] A weighting structure is provided on the support rod, a pull ring is fixedly connected to the bottom of the support rod, a hanging rope is provided on the pull ring, and a weighting block is fixedly connected to the bottom of the hanging rope. By providing the weighting structure, the overall weight of the support rod is increased, thereby preventing the support rod from extending for a long distance and affecting the movement of the robot body.

[0008] The support rod and the fixing ring are both provided with protective stripes. By providing the protective stripes on the support rod and the fixing ring, the support rod is prevented from sliding when supporting the robot.

[0009] A baffle is fixedly connected to the inside of the circular tube, and one side of the baffle is fixedly connected to one side of the support rod. By setting the baffle, the support rod is blocked and separated from the inside of the circular tube, so as to prevent the support rod from shrinking too long when shrinking into the inside of the circular tube, which affects the support effect of the support rod on the robot.

[0010] The inner wall of the circular tube is rotatably connected with a protrusion, and the outer wall of the protrusion fits the outer wall of the support rod. By setting the protrusion, the friction force of the contact area between the support rod and the circular tube is reduced, avoiding affecting the supporting effect of the support rod on the robot.

[0011] The interior of the water tank is fixedly connected with a partition plate. By arranging the partition plate, the interior space of the water tank is separated, and the weight inside the water tank is prevented from being excessively biased to the side and affecting the stability of the robot.

[0012] A scraper is fixedly connected to the robot body, and one end of the scraper is located above the wheels of the robot body. By setting the scraper, impurities adhering to the wheels of the robot can be cleaned to prevent excessive impurities on the wheels of the robot from affecting the stability of the robot.

[0013] The beneficial effects of the utility model are:

[0014] When the robot needs to be used, water is first added to the water tank. When the robot is moving, if it tends to tip over, the support rod will extend to the ground under gravity. At this time, water will squeeze the push block through the water collecting pipe, causing the push block to squeeze the round rod. After moving down, the round rod pushes the round rod and the top plate, so that the fixing ring fixes the support rod, thereby supporting the robot and preventing the robot from tilting.

[0015] By setting up a weighted structure, the overall weight of the support rod can be increased. When the robot is in a tilted state, the weight block will increase the weight of the support rod, allowing the support rod to move quickly and support the robot to prevent the robot from tipping over. At the same time, when the robot becomes stable, the weight block will return the support rod to its original position, thereby preventing the support rod from extending a long distance and affecting the movement of the robot body.
