Description

Technical Field

[0001] The utility model relates to the technical field of ray radiation alarm, in particular to a ray radiation alarm device. Background Art

[0002] Radiation alarms are safety devices used to monitor and warn personnel about the presence and intensity of radiation. These devices, commonly known as X-ray and gamma radiation alarms, detect and respond to the presence of X-rays and gamma rays, which can originate from sources such as medical equipment, industrial applications, scientific research laboratories, or nuclear power facilities.

[0003] After searching, the patent (application number: 202222544536.2) discloses a "multifunctional intelligent radiation alarm device". This device can be easily carried and installed, shortens the test and inspection period, and greatly improves the test rate. At the same time, the dual warning of sound and color makes the radiation alarm reminder more effective, and also prevents the physical warning tape from being blown onto the wires by the wind, causing power accidents, greatly improving its overall safety. However, the device has the following problems during use:

[0004] First, the device is relatively compact in structure, but when in use, the operator generally needs to hold the device close to the radiation area. Since the operator needs to use it at close range, there is a greater risk. In addition, the angle of the arc opening in the device is small, resulting in a smaller range of the entire X-ray radiation detection area. Once the device is fixed and installed, it is not easy to adjust, and there is a large blind spot in radiation detection. Utility Model Content

[0005] In view of the deficiencies of the existing technology, the present invention provides a ray radiation alarm device, which overcomes the deficiencies of the existing technology and effectively solves the problems of greater risks in close-range use and small radiation detection range.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A radiation alarm device includes a sleeve, a base is welded to the outer wall of one side of the bottom of the sleeve, and a handrail is slidably connected to the inner wall of the base, and elastic limit assemblies are fixedly connected to the inner walls of both sides of the base;

[0008] The outer wall of the other side of the sleeve is fixedly connected to a fixed sleeve, and the inner wall of the fixed sleeve is rotatably connected to a long rod, the outer wall of the long rod is fixedly connected to a worm wheel, and the outer wall of the worm wheel is engaged with a worm, and a handle is welded to the outer wall of one end of the worm wheel.

[0009] Preferably, the outer wall of one end of the long rod is fixedly connected to a clamp via bolts, and the inner wall of the clamp is fixedly connected to a radiation sensor.

[0010] Preferably, a radiation display is provided on one side of the sleeve, a signal line is connected between the radiation display and the radiation sensor, and an alarm is provided on the outer wall of one side of the radiation display.

[0013] Preferably, a U-shaped frame is welded to the outer wall of the fixed sleeve, and the worm is rotatably connected to the inner wall of the U-shaped frame.

[0014] Preferably, the elastic limiting component includes a sliding sleeve, a ball column slidably connected to the inner wall of the sliding sleeve, and a spring connected between the sliding sleeve and the ball column.

[0015] The beneficial effects of the utility model are:

[0016] 1. The designed radiation alarm device has an armrest that can be removed from the inside of the sleeve and is limited by the ball column inside the elastic limit assembly.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1, refer to Figures 1 to 2 A ray radiation alarm device includes a sleeve 1, a base 2 is welded to the outer wall of one side of the bottom of the sleeve 1, and a handrail 3 is slidably connected to the inner wall of the base 2, and elastic limit components 4 are fixedly connected to the inner walls on both sides of the base 2.

[0025] In this embodiment, the armrest 3 can be removed from the inside of the sleeve 1 and limited by the ball column inside the elastic limiting component 4. Handheld radiation detection is used instead. The radiation sensor 11 is far away from the detection personnel, and the operator does not need to use it at close range, so the safety factor is high. This device can be detected in a fixed manner through the base 2, or by handheld detection by personnel. Switching between the two modes can increase the scope of use of the device.

[0026] Example 2, refer to Figure 3 A ray radiation alarm device, the outer wall of the other side of the sleeve 1 is fixedly connected to a fixed sleeve 5, and the inner wall of the fixed sleeve 5 is rotatably connected to a long rod 6, the outer wall of the long rod 6 is fixedly connected to a worm gear 7, and the outer wall of the worm gear 7 is meshed with a worm 8, and a handle 9 is welded to the outer wall of one end of the worm gear 8.

[0027] In this embodiment, by rotating the handle 9 to drive the worm 8 to rotate, the long rod 6 inside the worm gear 7 can be controlled to rotate. Since the radiation sensor 11 is fixed to the long rod 6 by the clamp 10, the radiation sensor 11 can be adjusted 360°, which greatly improves the detection range of radiation.

[0028] Reference Figure 1 The outer wall of one end of the long rod 6 is fixedly connected to a clamp 10 by bolts, and the inner wall of the clamp 10 is fixedly connected to a radiation sensor 11.

[0029] Reference Figure 1 A radiation display 13 is provided on one side of the sleeve 1 , and a signal line 12 is connected between the radiation display 13 and the radiation sensor 11 , and an alarm 14 is provided on the outer wall of one side of the radiation display 13 .

[0030] Reference Figure 4The outer walls on both sides of the handrail 3 are provided with arc grooves 15, and the inner walls of the arc grooves 15 are provided with limiting holes 16.

[0031] Reference Figure 1 , fixing plates 17 are welded to the outer walls of both sides of the sleeve 1, and the radiation display 13 is fixedly connected between the two pairs of fixing plates 17 by bolts.

[0032] Reference Figure 1 A U-shaped frame is welded to the outer wall of the fixed sleeve 5, and the worm 8 is rotatably connected to the inner wall of the U-shaped frame.

[0033] Reference Figure 4 The elastic limiting component 4 includes a sliding sleeve, a ball column slidably connected to the inner wall of the sliding sleeve, and a spring connected between the sliding sleeve and the ball column.

[0034] Working principle: When the armrest 3 is set inside the sleeve 1, the base 2 can be placed on the ground so that the entire device adopts fixed numerical detection. On the contrary, the armrest 3 can be taken out from the inside of the sleeve 1 and limited by the ball column inside the elastic limit component 4. At this time, handheld radiation detection is used instead. During the detection process, the worm 8 is driven to rotate by rotating the handle 9, which can control the rotation of the long rod 6 inside the worm gear 7, and then control the radiation sensor 11 to adjust the detection angle. Once the radiation sensor 11 detects that the radiation value is too high, the radiation display 13 will display the radiation value and sound an alarm through the alarm 14.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
