The present application discloses a photovoltaic module monitoring device and a photovoltaic power generation system, wherein the photovoltaic module monitoring device includes: a DC power supply device and at least one bypass device; wherein: each of the bypass devices is only connected to Between the input end and the output end of the DC-DC converter corresponding to a photovoltaic module in the photovoltaic power generation system, used to bypass the connected DC when the photovoltaic module corresponding to the connected DC-DC converter has no power output ‑DC converter; the DC power supply device is connected to the DC bus of the photovoltaic power generation system, used to output DC current, and connected to a DC-DC converter corresponding to a photovoltaic module in the photovoltaic power generation system When the bypass is closed, the DC current at the output terminal of the DC power supply device is detected.

The invention discloses a forced sewage discharge device, which comprises a header tank, a sewage delivery pump, a forced discharge delivery pump, a filter and a liquid level and time delay controller, wherein a sewage inlet pipe is arranged on the header tank, and the output end of the sewage inlet pipe is communicated with the filter. The forced sewage discharge device is characterized in that the inside of the header tank is provided with the filter and a sewage storage device; one end of the filter is connected with the sewage delivery pump through a conduit pipe, and the other end of thefilter is connected with the sewage storage device through a solid sewage delivery pipe and a check valve; one end of the sewage storage device is connected with a water outlet pipe of the forced discharge delivery pump, and the other end of the sewage storage device is communicated with the outside of the header tank through a sewage outlet pipe; and the sewage delivery pump and the forced discharge delivery pump are communicated with the bottom of a tank body of the header tank through a water inlet pipe of the sewage delivery pump and a water inlet pipe of the forced discharge delivery pump respectively. The forced sewage discharge device improves the carrying capacity and the work efficiency of equipment.

The embodiment of the invention discloses a path planning method, device, equipment and storage medium. Determine the environmental grayscale grid map of the plane to be planned, after expanding the obstacle grid of the environmental grayscale grid map, traverse the expanded environmental grayscale grid map, and determine the first type of grid and the second type The second-type grid combines the three-dimensional information of the obstacle and the position of the second-type grid to determine the target traversal grid, and determines the target planning path based on the first-type grid, the second-type grid and the target traversal grid. By determining the first type of grid and the second type of grid respectively and combining the three-dimensional information of obstacles, the full coverage traversal of the expanded environmental gray scale grid map is achieved to determine the target traversal grid and the optimal target planning path The purpose is to achieve the effect of improving the operation efficiency of mobile equipment.

The invention discloses a tensile force adjusting device for mechanical arms. The tensile force adjusting device comprises the left mechanical arm and the right mechanical arm. Connecting holes are formed in the right end of the left mechanical arm. The right ends of the connecting holes are provided with a left connection arm. A fixing screw is arranged in the left connection arm. A right connection arm is arranged at the left end of the right mechanical arm. A connecting body is arranged between the left connection arm and the right connection arm. Link hinges are arranged at the two ends of the connecting body. A tensioning rod is arranged inside the connecting body. A tensile force adjusting rod is arranged above the connecting body. A fixing end is arranged above the tensile force adjusting rod. A rotary table is arranged above the fixing end. A screw hole is formed in the upper surface of the connecting body. The lower end of the tensile force adjusting rod is connected with a compression plug. Extendable holes are formed in the two ends of the bottom side face of the connecting body. Supporting rods are arranged in the middle of the rotary table. The problem that working efficiency of a traditional mechanical arm is lowered is solved, the problem that tensile force of an existing mechanical arm cannot be adjusted conveniently is also solved, and the difficult problem that the service life of an existing tensile force adjusting device is shortened is further solved.
