[0023] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0024] like Figure 6 As shown, a drainage ditch cover includes a drainage ditch cover body 16, on which a plurality of through slots 17 are opened, and the length a of the through slots 17 is greater than the width b of the through slots 17, so that the length a and the width b of the through slots 17 are arranged in a rectangular shape.

[0025] like Figure 1-2 , Figure 4 and Figure 6 As shown, a drainage ditch cover opening device for municipal engineering includes a handle 1, a long rod 2 is fixedly connected to the lower end of the handle 1, a round rod 3 is fixedly connected to the lower end of the long rod 2, the outer side of the round rod 3 is rotatably connected to a rotating bracket 4, a short rod 5 is fixedly connected to the rotating bracket 4, an angle adjustment group that can drive the short rod 5 to rotate and a control group that controls the angle adjustment group are installed on the long rod 2, and the control group is located on the long rod 2 near the handle 1. At this time, the short rod 5 is inserted into the lower side of the drainage ditch cover body 16 through the through slot 17 on the drainage ditch cover body 16, and then the angle adjustment group is operated by the control group , let the angle adjustment group drive the short rod 5 to rotate, so that the short rod 5 rotates to a horizontal state, so that the short rod 5 can be against the lower side of the handle 1. At this time, the handle 1 is held and pulled upward to pull the drain cover body 16 upward to complete the opening work. Since the long rod 2 and the short rod 5 are initially arranged in a straight line, the horizontal cross-sectional size of the opening device can be effectively reduced, so that the horizontal cross-sectional size of the opening device is smaller than the width b of the through groove 17, so that the opening device can be relatively easily inserted into the lower side of the drain cover body 16 to open the drain cover body 16.

[0026] Among them, the handle 1 and the long rod 2 are arranged in an L shape, so that the user can operate the long rod 2 and the round rod 3 through the horizontally arranged handle 1, which is more convenient for the user to apply force and operate.

[0027] like Figure 1-3As shown, the angle adjustment group includes a pull rope 9, the lower end of the pull rope 9 is connected to the rotating bracket 4, preferably the lower end of the pull rope 9 is connected to the side of the rotating bracket 4 in the rotation direction. At this time, the upper end of the pull rope 9 is connected to the control group. By pulling the pull rope 9 upward through the control group, the short rod 5 can be rotated upward until the short rod 5 rotates to a horizontal state.

[0028] The control group includes an additional handle 14 installed on the long pole 2 near the handle 1, and the additional handle 14 is located on the lower side of the handle 1. The upper end of the pull rope 9 is connected to the additional handle 14. At this time, the user holds the handle 1 and the additional handle 14 at the same time, and pulls the additional handle 14 upward, which can drive the pull rope 9 to be pulled upward.

[0029] like Figure 3 As shown, in order to reduce the movement range of the attached handle 14 and facilitate the user's operation, the long rod 2 is fixedly connected to the bracket body 10 near the grip 1, and the bracket body 10 is rotatably connected to a rope winding wheel 11. The upper end of the pull rope 9 is wound around the rope winding wheel 11, and a small meshing gear 12 overlapping the axis of the rope winding wheel 11 is fixedly connected to the rope winding wheel 11. The side of the small meshing gear 12 close to the attached handle 14 is meshed and connected with a large meshing gear 13 rotatably connected to the bracket body 10. The attached handle 14 is fixedly connected to the large meshing gear 13, and the number of teeth of the small meshing gear 12 is less than the number of teeth of the large meshing gear 13, preferably 1:2; at this time, when the attached handle 14 is pulled to rotate, the gear ratio setting of the small meshing gear 12 and the large meshing gear 13 can greatly reduce the movement range of the attached handle 14.

[0030] like Figure 1 and Figure 4 As shown, the connection between the rotating bracket 4 and the short rod 5 is fixedly connected with a sleeve 6, and the interior of the sleeve 6 is slidably connected with a slide rod 7, one end of the slide rod 7 extends to the outside of the sleeve 6 and is connected to the lower end of the pull rope 9. At this time, when the pull rope 9 is pulled upward, the magnet 8 will be pulled out from the inside of the sleeve 6, so that the short rod 5 and the slide rod 7 form an L-shaped structure, so that when the pull rope 9 pulls the slide rod 7 upward, the force is more reasonable.

[0031] At the same time, if Figure 4-5 As shown, a magnet 8 is fixedly connected to one end of the sleeve 6 away from the slide rod 7, and the slide rod 7 is made of iron. At this time, when the slide rod 7 is not subjected to force, the magnetic force of the magnet 8 can automatically reset the slide rod 7 to the inside of the sleeve 6, thereby reducing the horizontal cross-sectional size of the opening device.

[0032] Similarly, if Figure 3As shown, a spiral spring 15 is fixedly connected to the outer side of the round rod 3, the inner end of the spiral spring 15 is fixedly connected to the round rod 3, and the outer end of the spiral spring 15 is fixedly connected to the rotating bracket 4. At this time, when the short rod 5 rotates, the spiral spring 15 will be pulled to cause the spiral spring 15 to deform. When the short rod 5 is not subjected to force, the reset performance of the spiral spring 15 can automatically reset the short rod 5 to be in a straight line with the long rod 2.

[0033] The angle adjustment group can also be a motor fixedly connected to the long rod 2, and the output end of the motor and the round rod 3 are connected through a belt drive group, so that the short rod 5 can be driven to rotate by the motor, and the control group is a controller electrically connected to the motor, which can start and stop the motor.

[0034] The working principle of the utility model is as follows: the short rod 5 is inserted into the lower side of the drain ditch cover main body 16 through the through groove 17 on the drain ditch cover main body 16, and then the angle adjustment group is operated by the control group to allow the angle adjustment group to drive the short rod 5 to rotate, so that the short rod 5 rotates to a horizontal state, so that the short rod 5 can be against the lower side of the handle 1. At this time, the handle 1 is held and pulled upward to pull the drain ditch cover main body 16 upward to complete the cover opening work.

[0035] In summary, the technical solution can adjust the angle between the short rod 5 and the handle 1 according to user needs by setting an angle adjustment group and a control group for controlling the angle adjustment group, so that the long rod 2 and the short rod 5 can be arranged in a straight line when entering and exiting the through groove 17, and can effectively reduce the horizontal cross-sectional size of the cover opening device when entering and exiting the through groove 17, so that the horizontal cross-sectional size of the cover opening device is smaller than the width b of the through groove 17, so that the cover opening device can be more easily inserted into the lower side of the drain ditch cover main body 16 to open the drain ditch cover main body 16.

[0036] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
