The present invention opens a locking device. By virtue of the forward action it inserts the locking component 128 to the locking device 107a on the side of the holding part 109 so as to prevent the drawing of the storing box 111; by virtue of the back action it deviate the locking component 128 from the locking part 107a to allow the drawing out the storing box 111. Using the plate spring 129 set between the locking component 128 and the main body 113, it pushes the locking part 128 in the direction of inserting the locking part 107a. When it reaches the time that the holding part 109 is drawing out of the storing box 111, pull out the main body of the action bar which is supported by the axis and rotate at the outside of the box bulk 113 with finger to make the holding part 133b rotate, so that the locking component 128 resists to the push force of the plate spring 129 and moves to the direction which is opposite from the pushing direction and divorces from the locking part 107a. Thereby it can provide a structure-simple and cheap locking device.

The invention discloses a maintenance method without water supply shutdown for a large channel. The maintenance method comprises the steps of (1) manufacturing a maintenance bin which comprises a longitudinal steel beam extending from a channel slope to the bottom of the channel, wherein a door-shaped frame is connected to the longitudinal steel beam, a rubber gasket is arranged on a base on the outer side of the door-shaped frame, a water retaining steel plate is welded to the longitudinal steel beam and the inner side of the door-shaped frame, and a water sealing film bag is arranged at thebottom of the water retaining steel plate; (2) lifting the maintenance bin to the to-be-maintained area of the channel, and enabling the top opening to locate above the water level of the channel; (3)filling the water sealing film bag with water; (4) fully draining water in the bin; (5) entering the bin for maintenance by maintenance personnel; (6) filling the maintenance bin with water, discharging water from the water sealing film bag, and lifting the maintenance bin so as to complete the maintenance of the to-be-maintained area; and (7) maintaining other areas. The maintenance method has the advantages of safety and reliability, the actual engineering condition of the long large channel can be met, all aspects of influence caused by water supply shutdown is avoided, and economic benefits and social benefits are increased.

The micro force control system disclosed by the invention belongs to the technical field of precision measurement. The invention is mainly composed of a control and information output module, an optical measurement module and a micro force generation module. The control and information output module is used for measuring optical measurement signals, micro force generation, calculation, control and external communication of signals. The optical measurement module is used to establish the corresponding relationship between the measured value and the calculated control value and the micro force value, and comprehensively calculate and output the data of the micro force. The micro force generation module uses the electrostatic force method, and adopts the comb structure to improve the resolution and range of the electrostatic force to obtain the micro force value. The invention can accurately determine the magnitude of the tiny force value through the interference method to accurately change the displacement of the tiny force value under various environmental conditions of the tiny force value. The invention has high adaptability and accuracy and compact structure. and value metrics.

The invention discloses a geographical position information acquisition method. The method comprises the following steps: internal network equipment is connected with an internal and external network communication device through a serial port line and an Ethernet interface of the internal and external network communication device is connected with an external network; the internal network equipment sends a geographical position request message to the internal and external network communication device and the internal and external network communication device packages an HTTP (hypertext transport protocol) request message according to request parameters in the geographical position request message and sends the HTTP request message to corresponding position service providing equipment of the external network; and the internal and external network communication device receives an HTTP response message of the position service providing equipment from the external network, then packages a geographical position response message according to the response contents in the HTTP response message and sends the geographical position response message to the internal network equipment. The invention also discloses an internal and external network communication device. The method and the device have the following beneficial effects: the internal network equipment can directly request and obtain the geographical position information for the external network through the internal and external network communication device.
