The utility model discloses a kind of anti-slip mould transfer equipment, specifically related to mould transfer equipment technical field, including flatbed transfer trolley, automobile mould is placed in flatbed transfer trolley top, the both sides of flatbed transfer trolley are equipped with limit post, the both ends of limit post are rotatably connected with support rod group;The support rod group includes support rod box, lifting assembly for driving column box along support rod box to do linear movement is equipped in the support rod box, for driving limit post and automobile mould contact to limit automobile mould movement.The utility model is limited to the automobile mould placed in flatbed transfer trolley top by utilizing column box from top, to prevent the phenomenon that it slips in the process of transfer, after use, limit post and support rod group can be rotatably stored in the four sides of flatbed transfer trolley, also cannot occupy the space of flatbed transfer trolley top, ensure that the top of flatbed transfer trolley is not blocked, avoid to increase the operation difficulty for the hoisting of automobile mould.

A centrifugal fan with an air filtering device comprises a machine shell (8), an air outlet pipe (2) of the machine shell is a rectangular pipe body, the air filtering device is installed in the air outlet pipe, the air filtering device is composed of a filter screen (5) and a frame body (6), the filter screen is connected to the frame body, the frame body is of a bent structure, and the filter screen is bent along with the frame body. The filter screen is characterized in that the filter screen is of a curved surface structure after being bent along with the frame body. The centrifugal fan has the beneficial effects that the surface area of the filter screen is larger than the sectional area of the air outlet pipe, so that the interception amount of particulate matters in air can be greatly increased, the cleaning period of the filter screen is prolonged, and the shutdown frequency of the centrifugal fan is reduced; the air filtering device is convenient to assemble and disassemble, and the filter screen is convenient to clean.

The utility model discloses a kind of filter structures of measuring bacterial wet weight, including container a and container b, the container b is nested in container a, the top of the container b is provided with a platform, and the bottom end of container b is provided with support net, the container b is located above the position of support net and is provided with filter membrane, the top of the container a is provided with top cover, the gasket layer is nested in the top cover and is provided with spacer layer. In the utility model, the container b and container a of telescopic can be stable storage to the bacterial body to be filtered, facilitate subsequent filtrate work, cooperate the setting of top cover, gasket layer, platform, annular groove structure, can effectively guarantee the compactness of whole container storage;The upper layer membrane of double-layer membrane is large aperture membrane, part of bacterial body can be pre-filtered, the lower layer membrane is small aperture membrane, can intercept the remaining whole bacterial body, double-layer membrane has higher bacterial body interception flow than single-layer membrane, effectively improve filtrate efficiency, ensure the accuracy of subsequent weighing result.

The utility model discloses a hanging net for side slope ecological restoration soil dressing spray seeding, and relates to the technical field of side slope ecological restoration. Comprising a hanging net body which is used for covering a side slope; the hanging net anchoring pressing plate longitudinally covers the hanging net body in a pressing manner so as to cover the hanging net body and fix the hanging net body on the side slope; the first anchor nails are arranged on the hanging net anchoring pressing plate so as to fix the hanging net anchoring pressing plate on the side slope; the water diversion structure is arranged on the hanging net anchoring pressing plate and used for guiding accumulated water at the slope top position to the slope toe position from the position above the hanging net body. According to the device, the hanging net anchoring pressing plate is arranged on the hanging net body and combined with the anchor nails, the fixing reliability of the hanging net body is improved, meanwhile, the water diversion structure is arranged according to the area occupied by the hanging net anchoring pressing plate, water can be effectively drained to prevent soil from being scoured and taken away by heavy water, meanwhile, soil loss is effectively intercepted in combination with the soil dressing intercepting structure, and the soil dressing effect is improved. And the effect of soil dressing spray-seeding in ecological restoration of the side slope is better promoted.

The invention relates to a man-machine verification method and device, electronic equipment and a storage medium, and the method comprises the steps: responding to a man-machine verification request of a user, obtaining a proof-of-work verification code, and displaying the proof-of-work verification code to the user, the proof-of-work verification code being determined based on the request frequency of the man-machine verification request received by a system; in response to a verification operation of the user on the workload proof verification code, verifying user information submitted by the user; in response to verification passing of the user information, obtaining a background image and a geometric verification code, and displaying the background image and the geometric verification code to the user; and in response to the verification operation of the user on the geometric verification code, confirming that the man-machine verification is passed. According to the method, automatic attacks can be effectively resisted, and good user experience can be provided.

This invention relates to a video review method, system, and device based on non-verbal voice and coordination verification. The method includes acquiring the audio track of the video to be reviewed; detecting non-verbal voice events in the audio track and acquiring the event type and occurrence time of the non-verbal voice events; marking the corresponding occurrence time according to the event type to generate a risk identifier; extracting dialogue text within the vicinity of the occurrence time based on the risk identifier, and semantically verifying the risk identifier based on the dialogue text, generating an initial risk quantification value based on the verification result; when the initial risk quantification value is within a preset trigger range, reviewing the video footage within the occurrence time to correct the initial risk quantification value, thereby obtaining a target risk quantification value; and performing differentiated review of the video to be reviewed based on the target risk quantification value. Through the above methods, the accuracy of the review results can be improved.
