The present application relates to the field of program control technology, and in particular to a method for intelligent watering control for road sanitation. The method comprises the following steps: obtaining an image sequence of pedestrians on a predetermined watering path through a camera; judging whether the pedestrians are pulling their pets through a preset target recognition model according to the image sequence of the pedestrians; if there is a pedestrian pulling his pet, marking the pedestrian pulling the pet as a puller, and starting to execute the predetermined pre-watering control action in advance when approaching the puller, so as to reduce the interference of the pulled pet on the puller. The method for intelligent watering control for road sanitation provided by the present application can better avoid pedestrians on the road.

The utility model relates to a fixing structure and an energy storage system, and relates to the technical field of electrical equipment, the fixing structure comprises a fixing assembly, the fixing assembly comprises a clamping piece and a fixing piece which are connected, and the fixing piece is used for connecting the clamping piece into a box body, so that the clamping piece and the box body define an accommodating space for accommodating an electrical device; the clamping piece is used for limiting the electrical device in the accommodating space, and the clamping piece is used for bearing a heating assembly and a temperature control element of the electrical device. According to the arrangement, the structure is simple, the space utilization rate is improved, and the fixing assembly can simply and quickly fix the electrical device and provide certain vibration buffering. The heating assembly and the temperature control element of the electrical device are arranged on the clamping piece, so that the operation safety can be improved during testing and maintenance; the distance between the heating assembly and the temperature control element and the electrical device is reasonable, so that the working temperature of the electrical device is accurately monitored and adjusted, and the reliability of temperature control of the electrical device is improved.

The present invention provides a tooth surface quenching device for a rack, belonging to the field of mechanical technology. It solves the problem of poor quenching effect of the existing quenching device. The tooth surface quenching device of the rack includes a frame, a quenching head, a quenching liquid nozzle, a quenching plate with a mounting cavity, and a fixture for clamping and positioning the rack. The quenching head and the quenching liquid nozzle are fixed on the frame. The quenching head and the quenching liquid nozzle are both located above the fixture and opposite to the fixture. The quenching plate is arranged on the frame and can slide back and forth in the horizontal direction relative to the frame. The fixture is arranged in the mounting cavity of the quenching plate. The bottom surface of the fixture is a plane. The quenching plate is also provided with an adsorption member, and the adsorption member can absorb the bottom of the rack so that it is tightly attached to the bottom surface of the fixture. The adsorption member can generate an adsorption force to firmly absorb the bottom of the rack. Even if the rack is heated during the quenching process, it will not deform and warp, thereby improving the effect of tooth surface quenching and ensuring the quality of the product.

The application discloses a safety seat, comprising a base, a seat, an adjusting assembly and a backrest, the base is provided with a connecting boss extending in the front-rear direction and provided with a plurality of clamping holes in the front-rear direction; the seat is provided with a connecting groove matched with the connecting boss, so that the seat is adjustably arranged on the base; the adjusting assembly is arranged on the seat, and the clamping piece of the adjusting assembly is selectively clamped into any clamping hole to fix the seat; the backrest is detachably connected to the seat through a backrest pipe, the connecting boss is provided with a limiting groove, the backrest pipe is provided with a blocking piece, and the seat is provided with a limiting piece selectively extending into the limiting groove; when the backrest is removed, the clamping piece is clamped in the last clamping hole, and the limiting groove is matched with the limiting piece to lock the seat; when the backrest is installed on the seat, at least part of the blocking piece is located between the limiting groove and the limiting piece to release the locking of the seat, so that the application range is improved, and the safety and reliability are improved.

The application relates to the technical field of agricultural equipment, in particular to a main-path type water and fertilizer integrated intelligent irrigation regulating valve group which adopts the following technical scheme: a main-path type water and fertilizer integrated intelligent irrigation regulating valve group, comprising: a water pumping pipe, one end of which is communicated with a water source and the other end of which is connected with a water pumping pump; a circulating filtering assembly which is arranged on the water outlet side of the water pumping pump and comprises a first filtering tank body and a second filtering tank body connected in series; through the arrangement of two-stage gradient filtering, larger particles with a size of 1-3 mm are intercepted by a hard coarse filter screen, the subsequent system is prevented from being blocked, fine filter screens remove tiny impurities with a size of 0.1-0.5 mm, the cleanliness of irrigation water is ensured, the abrasion of the sprinkler and the dripper is reduced, and the service life of the equipment is prolonged. Meanwhile, under the driving of a servo motor, the scraper can efficiently clean the impurities on the coarse filter screen, the scraping effect is ensured and the filter screen is not damaged, the scraper can also work according to pressure or timing instructions, and energy is saved and efficiency is high. An adapter pipe forms a self-flow type anti-blocking channel, the risk of blockage is reduced, and stable operation of the assembly is ensured.
