Problems solved by technology

However, the explosion-proof tank still has the following defects: (1) When the electric push rod does not work in a power failure state, it may cause the tank mouth to be closed tightly and cause the danger of harmful substances leaking; (2) When the electric push rod stroke is not enough, The over-travel work of the electric push rod can make the lid close tightly, and the over-travel work of the electric push rod will affect the service life of the electric push rod

Embodiment Construction

[0017] Examples of the present invention Figure 1 ~ Figure 2 As shown, the specific implementation of this embodiment will be described in detail below in conjunction with the accompanying drawings:

[0018] The anti-biological and chemical tank includes a U-shaped tank body 2 extending in the up and down direction and having a tank opening at the upper end. There is a can lid 11 for closing and opening the can mouth. The can lid 11 is a conical structure with a small top and a large bottom that matches the shape of the can mouth passage. The O-shaped sealing ring arranged in the circumferential direction, the tank cover is hinged on the tank body through the hinge shaft, and the hinge shaft is arranged close to the edge of the tank mouth. In the closed state of the tank mouth of the channel, the tank cover 11 is connected with a drive device for driving the tank cover 11 to rotate around the hinge shaft to open or close the tank mouth through the tension chain 10. The drive...

Abstract

The invention relates to an anti-biochemical pot which comprises a pot body, wherein the pot body is provided with a pot opening and a pot opening channel communicated with the pot opening; a pot cover used for closing or opening the pot opening is arranged on the inner side of the pot body; a driving device used for driving the pot cover to move is connected above the pot cover through a flexible connecting body; and the driving device comprises an actuating mechanism, wherein the actuating mechanism is used for outputting rectilinear motion and provided with a first end and a second end relative to the first end, the first end is in transmission connection with the pot cover through a transmission mechanism or directly, and the first end or the second end is connected with a tensioning spring used for applying acting force to the pot cover, so that the pot opening is closed by the pot cover. The anti-biochemical pot has the advantage of simple structure, the stroke of the driving device can be prolonged, the pot cover is kept in the state that the pot opening is closed all the time, and the sealing reliability of the pot cover is guaranteed.

Description

technical field [0001] The invention relates to a biochemical prevention tank. Background technique [0002] The anti-biochemical tank is an important protective device in the transfer process of biochemical and toxic and other dangerous substances. It can effectively inhibit the lethality generated when biochemical or toxic and harmful substances are leaked. It is suitable for public security, airports, railway stations, customs and other important places and large-scale The security check of the event is in progress. [0003] The existing structure, such as the Chinese patent application "explosion-proof tank" with the authorized announcement number CN 201713005 U, includes a spherical tank body. The inside of the circular tank mouth of the spherical tank body is provided with a spherical crown tank cover for opening or closing the tank mouth. There is a support seat inside the crown tank cover, and a positioning shaft is arranged in the spherical tank body, and the suppo...
