Abstract

The utility model relates to an automatic alarm device for a radioactive source tank, mainly resolves the problem that the transportation prevention device of the prior radioactive source tank is not safe and can not give an alarm after the prior radioactive source tank is lost, and is characterized in that both sides of two symmetrical protection tanks(1) with holes(11) are connected through a chain(2) and a clasp(3) and then seated on a slide plate(8); the slide plate(8) and both sides of the slide plates are respectively equipped with a pull handle(10), a stop plate(4) and a position-limited plate(9). The stop plate (4) is close to a travel switch (5). The utility model enables that the radioactive source tank is safe and is not easy to lose and gives the alarm once the radioactive source tank is lost.

Description

The source container autoalarm

Technical field:

The utility model relates to a kind of alarm used in the oilfield test field, belongs to a kind of source container autoalarm.

Background technology:

In oilfield test construction, often use radioactive source to come the related parameter that has of measuring well sub-surface, if in use protect improperly, to cause leakage all be very harmful to environment and human body in case lose.In existing equipment; radioactive source is stored in and puts transportation onboard in the carrying shield; the protective pot that carrying shield is opened the door by circular side is fixed, and existing protective pot door lock is often easily opened carrying shield is lost, and lacks supervising device simultaneously; can't know in transportation whether carrying shield is lost; according to statistics in all radioactive source accidents, carrying shield is lost and is accounted for over halfly, and radioactive source leaks and not only causes human injury and environmental pollution; also cause enormous economic loss, and influence the ordinary production operation to enterprise.

The utility model content:

In order to overcome the deficiency that to report to the police after the dangerous and carrying shield of existing carrying shield transport protection device is lost, the utility model provides a kind of source container autoalarm, this source container autoalarm makes carrying shield safety in transportation be difficult for losing, in case have warning function after losing.

The adoptable technical scheme of the utility model is: this source container autoalarm comprises protective pot; the both sides that have the two symmetrical protective pots in hole connect the recoil on sliding panel by hinge and hasp; on the sliding panel and both sides have handle, baffle plate and limiting plate respectively, and baffle plate leans on mutually with travel switch.

The stroke of above-mentioned travel switch is 0.5cm.

The utlity model has following beneficial effect: the both sides of the protective pot of this source container autoalarm connect with hinge and hasp, and hasp can add padlock, guarantee that carrying shield protective pot in transportation can not be opened, carrying shield can not deviate from from protective pot and lose, overcome the radioactive source powder and leaked, avoided causing problems such as personal injury and environmental pollution; And protective pot is equipped with warning device, and in a single day carrying shield is lost also and can in time be found to give for change, avoids the generation of above-mentioned accident, guarantees to log well and normally carries out, and retrieves economic losses.

Embodiment:

Below in conjunction with accompanying drawing will the utility model is described in further detail:

By shown in Figure 1, this source container autoalarm comprises protective pot 1, as shown in Figure 3, the cover tape of protective pot 1 is porose 11, and two symmetrical both sides of protective pot 1 are fixed on the sliding panel 8 after connecting by hinge 2 and hasp 3, and hasp can add padlock, guarantee that carrying shield protective pot in transportation can not be opened, carrying shield can not deviate from from protective pot and lose, and has overcome the radioactive source powder and has leaked, and avoids causing problems such as personal injury and environmental pollution; On the sliding panel 8 and both sides have handle 10, baffle plate 4 and limiting plate 9 respectively; sliding panel 8 is limited not by limiting plate 9 can move left and right; handle 10 is pulled out sliding panel 8 during use; opening protective pot 1 puts into carrying shield; with sliding panel 8 returns, sliding panel 8 is fixed on the carriage bottom plate then by spring sheet-holder 7.And protective pot is equipped with warning device; as shown in Figure 2; baffle plate 4 leans on mutually with travel switch 5; in a single day carrying shield is lost baffle plate 4 and is broken away from travel switch 5, and as shown in Figure 4, travel switch 5 closed alarm circuit exists constitute loop loudspeaker 6 and send sound; even losing also, carrying shield can in time be found to give for change; avoid the generation of accident, guarantee to log well and normally carry out, and retrieved economic loss.

Claims
