The invention discloses a method for manufacturing video barrages based on an education cloud platform, and an electronic device. The method comprises the steps of: A, after receiving a barrage inputby a user, sending a request to join the barrage to a player; B, querying whether there is a free track by the player; and C, if there is a free track, querying whether there is a space at the heightof the free track, and if there is a space, playing the barrage at the height corresponding to the track and at the corresponding speed. In the invention, the barrages are synchronized with the videothrough the track design and follow respective own tracks to update the track speed in real time to meet the requirements of the barrage speed, and barrages of different sizes have different tracks toavoid the problem of collision.

The invention relates to a using method of an all-metal screw pump heavy oil injection and production integrated device. According to the technical scheme of the using method, the all-metal screw pumpheavy oil injection and production integrated device comprises an oil production pipe column, a fixing device and a wellhead device, the wellhead device is installed at the top of a sleeve, and the fixing device is installed above plugged surfaces; the oil production pipe column is fixed and supported through the fixing device and comprises an injection and production control device, an all-metalscrew pump, a pressure testing device and a positioning device; and the injection and production control device is installed at the upper part of the all-metal screw pump, the lower part of the all-metal screw pump is installed on the fixing device through the positioning device, and the pressure testing device is installed between the fixing device and the all-metal screw pump. The using methodof the all-metal screw pump heavy oil injection and production integrated device has the beneficial effects that firstly, frequent operation construction is not needed, and the whole all-metal screw pump or part of the all-metal screw pump is not needed to be lifted upwards and put down during steam injecting, so that the operating cost is reduced, and the probability of occurrence of safety accidents caused by operation is further reduced; and steam injecting is flexible, and a large amount of high temperature and high pressure steam is not needed to be injected into a stratum once, so that potential safety hazards caused by too high pressure of the one-time injected steam are reduced.

The invention discloses a transmission response method, device, server and system of a video intercepted content. The transmission response method comprises the following steps: receiving an interception instruction of current video by a foreground, acquiring an identifier of the current video, and determining an identifier of the video intercepted content according to the interception instruction; uploading the identifier of the current video and the video intercepted content identifier. The response server receives the video identifier and the video intercepted content identifier uploaded by an uploading party, searches a corresponding video file according to the video identifier, generates the video intercepted content corresponding to the video file according to the video intercepted content identifier after the corresponding video file is searched and performing associative storage on the video intercepted content and the information of the uploading party. A quick transmission function can be realized, the network bandwidth is saved, the transmission success rate is improved and the logic error rate is reduced.

The invention relates to a full-metal screw pump thickened oil injection-recovery integrated control device and method. According to the technical schemes of the full-metal screw pump thickened oil injection-recovery integrated control device and method, a center pipe is mounted in a casing inner cavity, a rotor connecting rod is mounted in an inner cavity of the center pipe and connected to a rotor of a full-metal screw pump through a screw pump connector, and a fixing ring is mounted in an inner cavity of the lower middle portion of the center pipe; a sliding ring is mounted on the outer wall of the rotor connecting rod, and a movable ring is mounted between the fixing ring and the sliding ring; and a cylinder sleeve is fixed to the outer side of the middle of the center pipe through a connecting protrusion, a steam injecting hole is formed in the lower side of the middle of the center pipe, a pressure relief hole is formed in the upper side of the middle of the center pipe, and thelower portion of the cylinder sleeve is matched with the steam injecting hole through a steam injecting piston to achieve opening and closing. The full-metal screw pump thickened oil injection-recovery integrated control device and method have the beneficial effects that the screw pump does not need to be lifted up and put down in steam injecting and pressure relief, the operation cost is reduced,and the occurrence probability of safety accidents caused by operation is also decreased; and steam injecting can be conducted according to the requirement of a stratum at any time, the constructioncost and time are reduced, and the thickened oil recovery efficiency is greatly improved.

The invention discloses a method for making video barrage based on an education cloud platform and an electronic device. The method includes steps: A. After receiving the barrage input by the user, sending a request to the player to add the barrage; B. the player Query whether there is an idle track; C, if there is an idle track, then inquire whether there is a vacancy at the height of the idle track, if there is a vacancy, then play the barrage at the corresponding height and corresponding speed of the track. In the present invention, the barrage is synchronized with the video through track design. And the barrage follows its own track, and the track speed can be updated in real time to meet the requirements of barrage speed. Bullet screens with different font sizes have different tracks, and there will be no collision problem.

The invention provides a sesame washing and draining device for the production of refined sesame seed oil, and aims to solve the problem that sesames are easily destroyed during the washing process in the prior art. The sesame washing and draining device comprises a washing box, an auger, and a draining machine. One end of the washing box is provided with a sesame inlet pipe and a water inlet pipe, and the other end of the washing box is provided with a discharge pipe. The auger is horizontally arranged in the washing box and is driven to rotate by a decelerating motor so as to convey the sesames that float on the water to the discharge pipe. The draining machine is arranged under the discharge pipe and is used to drain the washed sesames. The provided sesame washing and draining device has the advantages of simple structure and convenient operation, can wash the sesames, cannot destroy the sesame structure at the same time, and thus guarantees the quality of the produced refined sesame seed oil.
