The utility model discloses a primary and secondary separation composite sleeve column-mounted circuit breaker, which comprises a support frame, an upper insulator, a middle insulator and a disconnecting link, a driving mechanism is arranged at the lower end of the support frame, the driving mechanism comprises a fixed frame fixedly connected to the lower end of the support frame, the lower end of the fixed frame is fixedly connected with a mounting plate, and the mounting plate is fixedly connected with the middle insulator. And the front end of the mounting plate is fixedly connected with a metal plate. According to the on-column circuit breaker for primary and secondary separation and combination, the motor drives the rotating disc to rotate, so that the rotating disc swings the hitting ball through the connecting rope, and the hitting ball swings towards the outer side of the rotating disc under the inertia effect, so that the hitting ball is in contact with the metal plate; the purpose that the hitting ball conveniently passes through the friction strip and the metal plate to generate vibration force is achieved, then the metal plate makes a sound, the sound expels birds, and the birds are prevented from nesting on the surfaces of the upper insulator, the middle insulator and the lower insulator.

The present application belongs to the field of electric power, and particularly relates to an ecological bird prevention device for a power transmission line tower, comprising a cross arm and a clamp, and the clamp is connected to the cross arm. The device is driven by natural wind to rotate the fixed rod and the sleeve rod, and the sleeve rod drives the baffle to rotate, thereby preventing birds from standing in the adjacent areas of the line rod, the arc-shaped frame and the threaded sleeve, and preventing birds from nesting between the clamp and the line rod, avoiding the situation that the nest is removed after the birds nest, indirectly protecting the ecological environment, and avoiding the frequent activities of the birds near the porcelain bottle to pollute the porcelain bottle, and solving the problem that the birds frequently move on the wire near the cross arm after nesting to pollute the insulator, and the problem that the protection of the insulator by the partition plate cannot fundamentally solve the problem.

The utility model relates to the field of industrial wax production, specifically an discharging device for casting model wax, which comprises: a box body, a motor and an air pump arranged above it; a discharging component; by arranging the discharging component, the wax material on the inner wall of the box body can be scraped and cleaned by using a push rod in cooperation with a scraper. By utilizing the elastic property of the scraper, when the scraper contacts the inner bottom of the box body, it can bend along with the curvature below the box body to shovel the wax material at the inner bottom of the box body, improving the completeness of the discharging of the model wax and reducing the residue of the wax material; when the push rod drives the scraper to move down to scrape the wax material on the inner wall of the box body, through the motor, the push rod can be rotated to drive the connecting plate and multiple scrapers to rotate and descend, improving the coverage rate of the scraping of the wax material on the inner wall of the box body by the scraper, achieving the effect of completely scraping the wax material, and cooperating with the cutting knife on the surface of the shoveling part below the scraper, the wax material can be cut into strips, preventing the problem that the discharging is affected due to the too large size of the wax material.

The application provides a separator and a cleaning device, which comprises a water cup, an inlet water cavity is arranged in the water cup, the inlet water cavity is communicated with the outside of the separator, a first filter assembly is connected to the water cup, the first filter assembly is provided with a first water outlet, a cyclone channel and a first filter screen are arranged in the first filter assembly, the first water outlet is communicated with the inside of the first filter screen, a second filter assembly is arranged outside the water cup, the second filter assembly is communicated with the first filter assembly, the second filter assembly is provided with a second filter screen, the second filter screen is provided with a second water outlet, a water outlet element is internally provided with a water outlet channel, the water outlet channel is communicated with the first water outlet and the second water outlet, and the water outlet element is further provided with a third water outlet communicated with the water outlet channel.

This utility model discloses an injection mold for foam production, belonging to the field of injection mold technology. It includes a base, with a first support plate and a second support plate symmetrically distributed at the top of the base. A first cylinder is fixedly installed on the side of the first support plate away from the second support plate. The piston shaft of the first cylinder slides through the first support plate, and a mounting box is fixedly installed at the end of the piston shaft. A first mold is fixedly installed on the side of the mounting box away from the first support plate. This utility model, through the setting of the ejection assembly, uses a second reduction motor to drive a screw to rotate. The screw drives the mounting plate to move within the mounting box, the mounting plate pushes a support rod to move, and the support rod pushes the ejection plate to move within the mold cavity, thus ejecting the product. By ejecting the product through the ejection plate, it not only achieves demolding but may also reduce the damage caused during product removal.

The utility model relates to the field of ventilators, in particular to an anti-bird device for a downslope ventilator and the downslope ventilator with the anti-bird device. The anti-bird device is mounted on the ventilator framework; the anti-bird device comprises an anti-bird mechanism arranged on the ventilator framework, and the anti-bird mechanism comprises an anti-bird net arranged on the lateral ventilation opening; each anti-bird net comprises a plurality of single nets arranged on the ventilator framework; each single net comprises a net body frame, and a steel net layer is arranged on the net body frame; through the arrangement of the bird preventing device, the ventilation efficiency can be guaranteed, meanwhile, birds can be effectively prevented from entering the ventilator, the birds are prevented from nesting, inhabiting and excreting in the ventilator, and damage to the ventilator and the internal structure of a roof is reduced; the anti-bird net disclosed by the utility model is formed by splicing a plurality of single nets, so that the problem that a traditional integral anti-bird net is easy to interfere with a ventilator framework during installation can be reduced or avoided.

The invention discloses a left-right swing type intelligent electric power cabinet anti-bird device, and relates to the technical field of electric power cabinets. The device comprises a cabinet body, an L-shaped plate is fixedly installed above the back of the cabinet body, a driving rod is rotatably installed on the front face of the L-shaped plate in a penetrating mode, an elastic telescopic plate is fixedly installed on the outer wall of the driving rod in a penetrating mode, a U-shaped groove is formed in the bottom of the telescopic end of the elastic telescopic plate, and a cambered surface baffle is fixedly installed at the top of the elastic telescopic plate. According to the bird repelling device, the cambered surface baffle swings in a reciprocating mode through the driving rod so as to complete bird repelling work, birds are distinguished to adapt to noise type repelling through dynamic repelling, and therefore the nesting phenomenon is generated, in the swinging process of the cambered surface baffle, the top cambered surface design increases the bird stopping difficulty, and then the bird repelling effect is optimized; meanwhile, the top of the cambered baffle is cleaned by the scraper, so that the service life of the cambered baffle is prevented from being shortened due to dirt erosion.
