The invention provides a plate connecting device and a plate-type combined device. The plate connecting device comprises a sleeve base, a through hole, a limiting groove and an eccentric member. The sleeve base is a cylinder with a hollow inner cavity. The through hole is formed in the cylinder wall of the sleeve base. The limiting groove is formed in the inner side of the cylinder wall of the sleeve base and extends along the circumferential direction of the cylinder wall. The limiting groove comprises a starting end and a stopping end. The eccentric member is rotationally arranged in the sleeve base. An anti-slip tooth is arranged on the outer side face of the eccentric member. When the eccentric member is positioned at an initial rotation position, the anti-slip tooth is fastened at the starting end of the limiting groove to ensure the initial rotation position of the eccentric member.

The invention relates to a switching device, especially a contactor iron core and a contactor drive circuit. The invention overcomes the disadvantages of high driving power, high energy consumption and short service life in existing contactors, providing a low-power digital controlled contactor with built-in drive circuit and control port. The low-power digital controlled contactor comprises excitation coil, and dynamic and static iron cores, where the static iron core is stacked of silicon steel sheets and inserted with permanent magnet; the built-in drive circuit is connected with the excitation coil and used for driving the excitation coil by connecting external power supply and control signal. And the invention also provides a control system composed of the low-power digital controlled contactor. The invention has the beneficial effects of: low power consumption, easily driving, long service life, and being able to directly adopt nominal DC24V switching power supply to supply power, as well as remarkable energy saving effect.

The invention discloses a compartment of a cargo transporting vehicle. The compartment comprises a bottom compartment body and a tarpaulin supporting frame, waterproof tarpaulin is placed on the tarpaulin supporting frame, a plug is arranged at the bottom end of the tarpaulin supporting frame, the bottom compartment body is connected with a protection compartment body, vertical inserting grooves of a T-shaped or dovetail-shaped structure are formed in the two sides of the bottom compartment body and the two sides of the protection compartment body respectively, the vertical inserting grooves in the bottom compartment body and the vertical inserting grooves in the protection compartment body are correspondingly connected, connecting columns are inserted into the vertical inserting grooves, the shape of the connecting columns is matched with that of the vertical inserting grooves, and fixed seats are arranged on the connecting columns. The two outer sides of the bottom compartment body and the two outer sides of the protection compartment body are each provided with a T-shaped or dovetail-shaped transverse sliding groove, and a plurality of sliding blocks are arranged in the transverse sliding grooves. After the bottom compartment body is connected with the protection compartment body, cargoes in the compartment can still be protected through the n-shaped tarpaulin supporting frame.

The invention discloses a short-circuit ground wire combination head which comprises a female head and a male head which are matched in an inserted mode; the male head is columnar, the end of the malehead is used for being connected with a ground wire, the female head comprises a connecting frame used for being connected with a ground clamp, and an attaching part used for being attached to the male head to conduct the ground clamp and the ground wire is arranged in the connecting frame. Before the short-circuit ground wire combination head is used, the female head and the male head are respectively installed on the ground clamp and the ground wire. When the ground clamp and the ground wire need to be connected, only the male head needs to be inserted into the female head, and the attaching part in the female head can be tightly fitted with the outer side wall of the male head, so that the ground wire is conducted with the ground clamp. The ground wire and the ground clamp are connected in a plugging manner, so that the connection efficiency can be remarkably improved, and the connection process is flexible and convenient.

The invention mainly discloses a garbage compression liquid filtering machine, which has the technical scheme that the garbage compression liquid filtering machine comprises a machine frame, wherein an oil cylinder, a compression plate and a fixed filtering frame are arranged on the machine frame; filtering plates are arranged between the fixed filtering frame and the compression plate; a filtering chamber is formed between the filtering plates; a liquid inlet passage, a water discharge groove and a liquid outlet passage are respectively formed in each filtering plate; the water discharge groove communicates with the liquid discharging passage; filter cloth is embedded on the water discharging groove; a liquid inlet is formed in the fixed filtering frame; the liquid inlet communicates with the liquid inlet passage; support feet are symmetrically arranged on the bottom surface of the fixed filtering frame; a water collecting groove is formed between the support feet and the machine frame; the water collecting groove is positioned under the filtering plates; buffer mechanisms are uniformly distributed in the water collecting groove. The garbage compression liquid filtering machine has the advantages that the structure is simple; the connection is flexible; the filtering efficiency is high; the filtering effect is good; the garbage compression liquid is effectively treated; the recovery quantity of the filtering liquid is improved.
