The utility model provides a reversible crusher hammerhead, which relates to the technical field of crusher hammerheads, and comprises a hammerhead main body, a mounting groove of a rectangular groove-shaped structure is formed in the top end face of the hammer head body, and an auxiliary groove of a rectangular groove-shaped structure is formed in the position, located on the right side of the mounting groove, of the top end face of the hammer head body. A balancing weight is clamped in the mounting groove, a fixing hole for locking the balancing weight is formed in the balancing weight, the fixing hole is of a circular hole-shaped structure, the balancing weight is of a rectangular block-shaped structure, and the outer wall of the balancing weight is in contact with the inner wall of the mounting groove. The arrangement of the locking assembly is very ingenious, and the spring elastically pushes the locking rod to be inserted into the balancing weight fixing hole, so that stable locking of the balancing weight is realized; locking can be easily relieved by pushing the handle block, and the balancing weight is convenient to replace; the blocking seat seals the auxiliary groove, dust is prevented from invading and affecting the performance of the spring, the service life of the assembly is prolonged, and meanwhile the locking rod is convenient to maintain and replace.

The invention discloses a fire grate, a combustor and a gas water heating device, the fire grate comprises a fire grate main body, a flow channel used for circulating combustion gas is formed in the fire grate main body, and the fire grate main body is provided with a gas inlet and an outlet which are communicated with the flow channel; the outlets comprise a first group of outlets positioned on the upper end surface of the fire grate main body and a second group of outlets positioned on the side wall of the fire grate main body; the first group of outlets are arranged at intervals in the length direction of the fire grate to form a plurality of outlet combination units, and a spacing part is arranged between every two adjacent outlet combination units; the guiding shell is arranged outside the side wall of the fire grate body and right faces the second set of outlets, the guiding shell is provided with an upper end and a lower end in the height direction, a fire transferring component is arranged at the upper end of the guiding shell or the position close to the upper end, and the fire transferring component corresponds to the interval part and is used for transferring flames between the guiding shell and the fire grate body to the adjacent fire grates. The combustion sufficiency is not affected, meanwhile, the fire transfer performance is improved, and the low-noise combustor is well applied to a low-noise combustion system.

This utility model discloses an instant heater, including a shell, an instant heating element, a circuit board, a thermostat, and a water pump. The circuit board is provided with a power input terminal, a first branch, a second branch, and a power output terminal. The first branch is connected to a drive switch, a thermostat, and the instant heating element in sequence. The second branch is connected to a step-down rectifier module, a control module, and a water pump in sequence. One end of the thermostat is close to the instant heating element. The first branch after the drive switch is also provided with a first welding port and a second welding port of the thermostat, a first welding port of the heating element, and a second connection terminal of the heating element. The control module is provided with a water pump control terminal and a drive switch signal control terminal. The water pump control terminal and the power output terminal are also provided with a first welding port and a second welding port of the water pump. This instant heater has a simple and stable electrical connection between the circuit board, the thermostat, the water pump, and the heating element, and the components are compactly arranged.

The invention discloses an ultra-long-distance submarine cable laying device and method, and relates to the technical field of submarine cable laying, the ultra-long-distance submarine cable laying device comprises a base, the bottom of the base is connected with anchoring supporting legs, the upper part of the base is connected with a submarine cable clamping mechanism used for clamping a submarine cable, and the submarine cable clamping mechanism is connected with a sliding block; the sliding block is slidably connected with a sliding rod parallel to the axis of the submarine cable, the base is assembled and connected with a counter-force frame at the rear end of the sliding rod, the counter-force frame is connected with a hydraulic push rod, the output end of the hydraulic push rod is connected with the submarine cable clamping mechanism, and the submarine cable clamping mechanism is driven by the hydraulic push rod to do linear reciprocating motion along the sliding rod; the submarine cable clamping mechanism is used for clamping the submarine cable in the pushing construction process, and then continuous and uniform axial pushing force is applied to the submarine cable through the hydraulic push rod and forms a forward pulling-backward pushing synergistic effect with land side dragging force; the risks of cable stretching, armored layer offset, insulating layer damage and the like caused by too large dragging force are effectively relieved.
