[0019] Specifically, please refer to Figures 1 to 3 , Figure 1 Schematic diagram of the overall structure of the electric shovel with self - adjusting viewing angle monitoring provided by the embodiment of the present application, Figure 2 Schematic diagram of the partial structure at the camera component provided by the embodiment of the present application, Figure 3FIG. 0 is a partial structural schematic diagram of the connection between the rotating member and the camera probe provided by the embodiment of the present application. The electric shovel 100 with self-adjustable viewing angle monitoring includes an electric shovel main body 110, a boom 120, a swing arm 130, and a bucket 140. The boom 120 is inclined and fixed on one side of the electric shovel main body 110. The swing arm 130 is drivingly connected to the middle of the boom 120. The bucket 140 is connected to one end of the swing arm 130. The swing arm 130 can be rotated under the drive of a power device, so as to drive the bucket 140 at its end to perform actions such as upward flipping or falling. Since the boom 120, the swing arm 130, the bucket 140, etc. are all prior arts and have been fully disclosed and are well-known to those skilled in the art, therefore, the above structures and their working principles will not be elaborated here. The electric shovel 100 with self-adjustable viewing angle monitoring includes a monitoring device. The monitoring device is used to monitor the bucket 140 of the electric shovel and transmit the real-time picture to the cab. The monitoring device includes a camera component 150 and a display component. The camera component 150 is used to collect video information, and the display component is used to display the above video information. The display component is located in the cab of the electric shovel main body 110 and is electrically connected to the camera component 150. The camera component 150 includes a camera probe 151. The camera probe 151 is a prior art and can be set with reference to the monitoring probe. The tail end of the camera probe 151 is fixedly connected to a rotating member 152. The camera probe 151 can be connected to the rotating member 152 in various forms such as interference fit, riveting, welding, or bonding. During the connection process, the stability between the camera probe 151 and the rotating member 152 should be ensured to prevent the camera probe 151 from falling off or detaching from the rotating member 152 during the subsequent rotation of the rotating member 152. The middle of the rotating member 152 is hinged to the middle of the boom 120, and the rotating member 152 can rotate around the hinge point. One end of the rotating member 152 away from the camera probe 151 forms a first connection point 152a. The first connection point 152a is connected to the tail end of the swing arm 130 through a linear rope 160. When the swing arm 130 rotates under the drive of a power device, the tail end of the swing arm 130 will move along an arc trajectory. At this time, the tail end of the swing arm 130 will pull the linear rope 160. The linear rope 160 should have a certain elasticity. The linear rope 160 will pull the rotating member 152 to rotate. The rotating member 152 rotates with its hinge point with the boom 120 as the fulcrum. At this time, the camera probe 151 at the end of the rotating member 152 will be lifted or lowered accordingly. A second connection point 152b is provided between the hinge point of the rotating member 152 and the first connection point 152a on the rotating member 152. An elastic member 170 is connected at the second connection point 152b. The other end of the elastic member 170 is connected to the boom 120. When the swing arm 130 falls and the bucket 140 lands, at this time the linear rope 160 will be in a relaxed state. The elastic member 170 returns to its original position under the action of its own elastic potential energy and drives the rotating member 152 to return to its initial position. The camera probe 151 will also return to its initial position and continue to monitor with the monitoring angle at the initial position.
[0020] As can be seen from the above, in the embodiments of the present application, by setting up a monitoring device, the bucket 140 can be monitored in real time and the monitoring screen can be transmitted into the cab. The driver can monitor the working conditions at the bucket 140 at any time, eliminating the influence caused by the blind spots of view between the cab and the bucket 140. In the present application, the monitoring device includes a camera probe 151. The camera probe 151 is connected to a transmission member, and the transmission member is respectively connected to the tail end of the swing arm 130 and the boom 120 through a linear rope 160 and an elastic member 170. In the present application, during the process of the swing arm 130 driving the bucket 140 to perform an action, the swing arm 130 can drive the transmission member to change the monitoring view angle of the camera probe 151 through the linear rope 160, so that the monitoring view angle of the camera probe 151 can always monitor the bucket 140 part. And after the bucket 140 lands, under the action of the elastic member 170, the transmission member will be reset, and the camera probe 151 can restore the initial monitoring angle.
[0021] In some embodiments, the elastic member 170 is a tension spring. By setting the elastic member 170 as a tension spring, the tension spring has advantages such as high service life and low acquisition cost.
[0022] In some embodiments, the linear rope 160 is an elastic rope made of natural latex. The elastic rope made of natural latex has excellent elasticity and durability, can withstand high-intensity operations and is not easy to break. And it has different resistance levels, which is easy to select.
[0023] In some embodiments, the rotating member 152 includes a connecting cylinder 152c arranged in a cylindrical shape. One end of the connecting cylinder 152c is an open end and the other end is a closed end. A plurality of through grooves 152d are opened at the open end, and the plurality of through grooves 152d divide the open end of the connecting cylinder 152c to form a plurality of connecting pieces 152e. A wire passing hole is opened at the closed end of the connecting cylinder 152c. In the embodiments of the present application, through the above settings, the camera probe 151 can be inserted into the open end of the connecting cylinder 152c, and then after the plurality of connecting pieces 152e are turned over, the connecting pieces 152e are pressed against the camera probe 151 to fix the camera probe 151.
[0024] In some embodiments, a dust cleaning assembly 180 is included. The dust cleaning assembly 180 includes a positive pressure blower 181. An air outlet end of the positive pressure blower 181 is communicated with an air delivery pipe 182. The other end of the air delivery pipe 182 extends to the ray component and is then communicated with a blowing hood 183. The blowing hood 183 is arranged facing the imaging probe 151. In the embodiments of the present application, through the arrangement of the above-mentioned dust cleaning assembly 180, the positive pressure blower 181 blows air through the blower to the blowing hood 183, and the air flow will finally act on the imaging probe 151, and the dust on and around the imaging probe 151 can be blown away, so that the picture captured by the imaging probe 151 remains clear.
[0025] In some embodiments, a heating box 184 with two open ends is communicated with the middle of the air delivery pipe 182. The heating box 184 is fixed on the moving arm 120, and at least one heating wire is arranged inside the heating box 184. In the embodiments of the present application, through the above arrangement, when the temperature changes or in a foggy weather, the heating box 184 can be turned on, and the gas in the air delivery pipe 182 will be heated by the heating box 184 and then warmed up. Thus, when the air flow is blown from the blowing hood 183 to the imaging probe 151, it will have a certain temperature, which is convenient for removing the water mist on the imaging probe 151.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be covered by the scope of the claims and the description of the present application.
