[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 4 This utility model provides a technical solution: an automated control device for a sewage treatment plant, including a mounting base 1, a control cabinet 101 on the top of the mounting base 1, protective shells 102 on both sides of the top of the mounting base 1, a connecting plate 103 fixedly connected to the top of the mounting base 1, a cavity inside the mounting base 1, an opening and closing component 2 on the inner side wall of the cavity, and two support components 3 on the front of the mounting base 1.

[0029] The opening and closing assembly 2 includes a motor 201 fixedly connected to the inner wall of the cavity, providing power support for the automated operation of the device. The output end of the motor 201 is splinedly connected to a transmission rod. A first gear 202 is fitted on the surface of the transmission rod. A second gear 203 meshes with the surface of the first gear 202, transmitting and converting the power output by the motor 201. A bidirectional lead screw 204 is fixedly inserted through one side of the second gear 203, driving two telescopic cylinders 205 threadedly connected to it to perform relative or opposite linear movements. Two telescopic cylinders 205 are threadedly connected to the surface of the bidirectional lead screw 204. A connecting block 206 is installed at one end of the telescopic cylinder 205. The top of the connecting block 206 is fixedly connected to the bottom of the protective shell 102. The motor 201 is a DC geared motor with a power of 50W and a speed of 1400rpm. The bidirectional lead screw 204 adopts a trapezoidal thread with a pitch P=5mm.

[0030] The support assembly 3 includes two mounting blocks 301 fixedly connected to the front of the mounting base 1. A rotating groove is formed on the front of each mounting block 301. A support arm 302 is rotatably connected to the inner wall of the rotating groove, allowing it to rotate around the groove. A circular groove is formed at the top of the support arm 302, and a locking rod 303 is movably connected to the inner wall of the circular groove. A spring 304 connects the bottom of the locking rod 303 to the inner bottom wall of the circular groove. Multiple locking holes adapted to the locking rod 303 are formed on the inner top wall of the rotating groove. The locking rod 303 engages with one of these locking holes, and under the action of the spring 304, it cooperates with the locking hole on the inner top wall of the rotating groove. The support arm 302 can be fixed at different angle positions to lock the angle of the support arm 302. The top of the support arm 302 is provided with a threaded hole, and the inner side wall of the threaded hole is threaded with a threaded rod 305. By rotating the threaded rod 305, the height of the support plate 306 can be adjusted, thereby further precisely adjusting the support height of the device. The bottom of the threaded rod 305 is equipped with a support plate 306, and the included angle between the centers of adjacent locking holes is 45°, realizing angle adjustment within the range of 0°~180°. The spring 304 (elastic coefficient k=5N / mm) and the threaded rod 305 adopt M12×2 fine thread with a pitch of 2mm.

[0031] The top of the telescopic cylinder 205 is fixedly connected to a limiting block 4. The inner top wall of the cavity is provided with a limiting groove that matches the limiting block 4. The limiting block 4 is movably connected to the inner side wall of the limiting groove to prevent the telescopic cylinder 205 from shifting or rotating during movement, thereby ensuring that the protective shell 102 can open and close smoothly and accurately.

[0032] Multiple limiting rods 5 are fixedly connected to the inner wall of the protective shell 102. Multiple slots that are compatible with the limiting rods 5 are opened on one side of the connecting plate 103, which can effectively prevent the protective shell 102 from shaking or shifting due to external vibration or slight collision, and better protect the control cabinet 101.

[0033] A shock-absorbing block 6 is fixedly connected to the top of the connecting plate 103, and a protective top 7 is fixedly connected to the top of the shock-absorbing block 6. The protective top 7 is inclined. The shock-absorbing block 6 reduces the impact of vibration on the electronic components inside the control cabinet 101, and the protective top 7 allows rainwater, debris, etc. that fall on it to slide off automatically.

[0034] Each of the two protective shells 102 is fixedly connected to a sealing gasket 8 on one side opposite to the other. The sealing gasket 8 is made of rubber and can fill the gap between the protective shells 102 to further prevent dust, moisture, insects and other substances from entering the control cabinet 101.

[0035] A rotating block 9 is fixedly connected to the top of the threaded rod 305. A through hole is opened on one side of the rotating block 9, and a handle 10 is provided on the inner wall of the through hole. Using the handle 10, adjustments can be made more easily and precisely, which improves the convenience and efficiency of adjusting the support component 3.

[0036] In this invention, the working steps of the device are as follows:

[0037] First step: When it is necessary to open or close the protective shell 102, start the motor 201 installed on the inner side wall of the cavity of the mounting base 1 to drive the first gear 202 to rotate. According to the gear transmission principle, the rotation of the first gear 202 will drive the second gear 203 to rotate. When the second gear 203 rotates, the bidirectional lead screw 204 fixedly connected to it will also rotate synchronously. The surface of the bidirectional lead screw 204 has two sections of threads with opposite directions of rotation. The two telescopic cylinders 205 threaded to its surface will make relative or opposite linear movements as the lead screw rotates. The connecting block 206 fixedly connected to one end of the telescopic cylinder 205 is connected to the bottom of the protective shell 102. Therefore, the linear movement of the telescopic cylinder 205 will drive the protective shell 102 to open and close, thereby realizing the protection of the control cabinet 101 or the opening of the operating space.

[0038] The second step: First, press down on the locking rod 303 to disengage it from the current locking hole, overcoming the elastic force of the spring 304. At this time, the support arm 302 can rotate around the inner wall of the rotating groove. After adjusting to a suitable angle, release the locking rod 303. Under the elastic force of the spring 304, the locking rod 303 will re-lock into the corresponding locking hole, thereby fixing the angle of the support arm 302. By rotating the threaded rod 305, due to the threaded engagement between the threaded rod 305 and the threaded hole at the top of the support arm 302, the threaded rod 305 will make a vertical linear motion, thereby driving the bottom support plate 306 to move up and down, realizing the adjustment of the support height to adapt to different installation and support requirements.
