Description

Technical Field

[0001] The utility model relates to the field of open environment ray detection safety configuration, in particular to a control ball device and a ray detection system for a radiation monitoring area. Background Art

[0002] At present, most X-ray detection needs to be carried out in an independent X-ray detection room, because when the X-ray detection room is established, materials are applied to prevent radiation from breaking through the X-ray detection room, thereby avoiding harm to people outside.

[0003] However, the application specifications and application environment of the X-ray inspection room are greatly restricted. For example, the specifications exceed the capacity of the X-ray inspection room, or when performing X-ray inspection on equipment in service, it is not applicable. In this case, X-ray inspection needs to be carried out outdoors in an open environment.

[0004] Currently, when conducting X-ray inspections in open outdoor environments in factories, manual intervention in the inspection area, such as cordoning off areas and issuing notices, is often employed to prevent physical harm to personnel during the inspection process. However, this intervention relies heavily on human observation and awareness, resulting in high risks and hindering the normal conduct of on-site inspections. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the existing technology in which excessive reliance on manual observation when monitoring radiation detection areas in open areas leads to untimely reminders of risk avoidance for personal injury. A control ball device and a radiation detection system for radiation supervision areas are provided. The radiation detection area is periodically monitored by the control ball, thereby improving the continuous monitoring capability of the detection area and preventing people from accidentally entering the detection area and being injured.

[0006] The purpose of this utility model is mainly achieved through the following technical solutions:

[0007] A control ball device for a radiation monitoring area includes a control ball, a rotating base is provided at the bottom of the control ball, a tripod is provided below the rotating base, a monitoring panel is provided on the side of the control ball, and a fixed connection portion is provided between the rotating base and the tripod, the fixed connection portion is rotatably connected to the rotating base, and the fixed connection portion and the tripod can be locked and hinged;

[0008] The bottom end of the tripod leg is provided with a leg adsorption end head, and the leg adsorption end head is in contact with the ground.

[0009] Currently, when conducting radiation inspections in open areas, areas are usually demarcated and supervisors are appointed to prevent other people from accidentally entering the inspection area. However, this not only relies too much on supervisors, but also easily creates blind spots in supervision, posing a risk of radiation damage to personnel.

[0010] In the embodiment of the present application, the detection area is monitored by rotating the control ball. The monitoring panel can effectively observe whether there are people who have mistakenly entered the detection area. When it is detected that someone has mistakenly entered, the control ball can avoid personal injury by alarming and shutting down the radiation detection device, thereby achieving the purpose of avoiding the risk of radiation injury.

[0011] The rotating base can help the control ball adjust the monitoring angle, so that the monitoring panel can monitor the entire radiation detection area. The tripod legs are used to support the control ball and adjust the height of the control ball, thereby reducing monitoring blind spots.

[0012] Since the embodiments of the present application are in an open environment, and the open environments involved are mostly factory environments and field environments, there are uncertain natural environmental influences, such as the occurrence of external forces such as crosswinds, which can make the control ball unable to maintain stability under the action of the three-legged legs, and easily tilt and other problems. The embodiments of the present application increase the negative pressure effect on the bottom of the three-legged legs by providing a leg adsorption end at the bottom of the three-legged legs, so that the three-legged legs can have a certain grip, rather than just support ability. Through the mutual coordination of support ability and grip, it can more effectively ensure that the posture of the control ball and the three-legged legs remains stable, thereby improving the monitoring stability of the control ball. The negative pressure of the leg adsorption end can act on the factory floor and the stable ground in the field. The embodiments of the present application are not suitable for working conditions such as sandy ground that cannot provide stable adsorption force.

[0013] Furthermore, the fixed connection portion includes a fixed rod, one end of which is fixed to the control ball, and the other end of which is fixed to an extension rod body, the outer cover of the extension rod body is provided with a hinge joint, the hinge joint is detachably fixedly connected to the extension rod body, and the end of the extension rod body is provided with an anti-slip end head;

[0014] The tripod legs are hinged to the hinged joint, and the hinged joint is provided with a locking buckle capable of limiting hinged rotation.

[0015] In this embodiment of the present application, the fixing rod is used to support the control ball and provide a base for the hinged joint and the tripod legs. By extending the rod body, the height of the hinged joint can be effectively adjusted, thereby adjusting the height of the control ball. The locking buckle can effectively limit the hinge angle of the tripod legs, thereby preventing the tripod legs from moving during use and affecting the stability of the control ball.

[0016] Furthermore, the tripod leg includes a hinged end portion, and the hinged end portion and the fixed connection portion can be locked and hinged;

[0017] A leg fixing end is fixed on the hinged end, a leg telescopic rod is detachably fixed to the leg fixing end, and the leg adsorption end is fixed to the bottom end of the leg telescopic rod.

[0018] In the embodiment of the present application, the tripod is able to effectively adjust the angle between the tripod and the ground by hingedly connecting the hinged end and the fixed connection part, thereby adjusting the support height of the control ball by the tripod, thereby achieving the purpose of adjusting the height of the control ball, so that the control ball can complete the monitoring of the radiation detection area at an appropriate height, and at the same time, it can also observe the accidental entry of personnel at an appropriate height, avoiding the omission of personnel observation due to monitoring blind spots when the height is too high or too low.

[0019] Furthermore, the support leg adsorption end includes a support shell, a negative pressure maintaining component is provided in the support shell, a bellows is provided on the negative pressure maintaining component, the bellows is communicated with the negative pressure maintaining component, a pull rope is provided on the bellows, the pull rope passes through the support shell, and the end of the pull rope is detachably fixedly connected to the tripod leg;

[0020] An adsorption pad is provided at the bottom of the supporting shell. A plurality of adsorption holes are provided on the adsorption pad. The negative pressure maintaining component is communicated with the adsorption holes.

[0021] At present, when fixing the tripod legs, expansion bolts are usually driven into the ground to fix the tripod legs. This can also prevent the tripod legs from tipping over due to external forces. However, this method not only requires destroying the ground, but also requires corresponding tools to achieve fixation, which is more complicated to use.

[0022] Today's factory environments and field equipment working environments usually have a good foundation and the flatness of the ground is also guaranteed, so the use of expansion bolts driven into the ground has relatively large side effects, causing damage to the site and increasing the difficulty of subsequent restoration.

[0023] In the embodiment of the present application, the use of negative pressure to increase the grip of the tripod legs can effectively avoid damage to the ground. At the same time, it is sufficient to cope with the damage to the supporting state of the tripod legs caused by most external forces, which can create favorable conditions for protecting the stability of the tripod legs.

[0024] The negative pressure effect in the embodiment of the present application is achieved by the expansion and contraction of the bellows. The adsorption hole can enhance the grip of the support adsorption end through adsorption. The support shell is used to provide supporting force and protect its internal structure. The bellows is stretched under the action of the pull rope, thereby exhausting the negative pressure maintaining component to form negative pressure. The pull rope maintains the negative pressure formed in the adsorption end of the leg through a detachable fixed connection with the tripod leg so that it can remain continuous and stable.

[0025] The negative pressure acts on the ground through the adsorption holes, and the adsorption pad is used to ensure the stable existence of the negative pressure in the adsorption holes.

[0026] Furthermore, each of the adsorption holes is provided with a partition net, and the partition net can completely cover the cross section of the adsorption hole.

[0027] The adsorption holes filter the ground debris through the partition net to prevent the debris from entering the negative pressure maintaining component.

[0028] Furthermore, the adsorption holes are evenly distributed around the center of the adsorption pad.

[0029] The circumferentially uniform distribution of the adsorption holes can effectively resist external forces in all directions and avoid the phenomenon of poor local grip.

[0030] Furthermore, the adsorption pad is outer-coated with a sealing inner ring, the sealing inner ring is outer-coated with a sealing outer ring, and the sealing outer ring, the sealing inner ring and the adsorption pad are fixedly connected in sequence.

[0031] In the embodiment of the present application, the outer sealing ring is made of hard material, and the inner sealing ring is made of soft material, thereby ensuring that the outer sealing ring and the inner sealing ring can effectively ensure the stability of negative pressure adsorption.

[0032] Furthermore, the negative pressure maintaining component includes a negative pressure channel, a lower sealing port is provided at the bottom of the negative pressure channel, the lower sealing port is communicated with the adsorption hole, an expansion section is provided above the lower sealing port, the channel diameter of the negative pressure channel in the expansion section gradually increases from bottom to top, a straight pipe section is provided above the expansion section, the channel diameter of the negative pressure channel in the straight pipe section is the same, a contraction section is provided above the straight pipe section, the channel diameter of the negative pressure channel in the contraction section gradually decreases from bottom to top, and an upper sealing port is provided at the top of the negative pressure channel;

[0033] A blocking ball is provided in the negative pressure channel. The diameter of the blocking ball is larger than the diameter of the upper blocking port, and the diameter of the blocking ball is larger than the diameter of the lower blocking port.

[0034] In an embodiment of the present application, the negative pressure in the negative pressure channel is provided by suction through the bellows. An upper sealing port is provided at the top of the negative pressure channel, which can prevent the sealing ball from falling out when the suction force is large. The lower sealing port of the negative pressure channel is used to carry the sealing ball to prevent the adsorption holes on the adsorption pad from releasing pressure. The middle section of the negative pressure channel is provided with a larger cavity in the middle of the negative pressure channel through the arrangement of an expansion section, a straight pipe section and a contraction section. The cavity can accommodate various impurities sucked from the ground to prevent them from entering the bellows and affecting the sealing of the bellows, thereby affecting the provision of negative pressure.

[0035] The embodiment of the present application provides negative pressure by pulling the bellows with a rope, which can simply and effectively enhance the grip of the tripod legs and avoid providing more power supply, thereby facilitating construction and disassembly.

[0036] The support shell and the tripod legs in the present application can be fixed in a detachable manner, thereby facilitating the replacement of the leg adsorption end and avoiding failure of the leg adsorption end during use.

[0037] Furthermore, a support rod is fixed on the tripod support leg, and a lifting ring is fixed on the end of the pull rope, and the lifting ring can be hooked on the support rod.

[0038] The embodiment of the present application completes the supply of negative pressure to the adsorption end of the tripod leg through the cooperation of a pull rope and a hanging ring. The hanging ring can maintain the state of the bellows through the limitation of the support rod, thereby avoiding pressure relief at the adsorption end of the leg.

[0039] The control ball ray detection system for radiation supervision area includes a radiation area supervision device for monitoring the radiation detection area of ​​an open field, and the radiation area supervision device is the control ball device for radiation supervision area.

[0040] In an embodiment of the present application, the control ball device can monitor the radiation detection area to avoid radiation injuries to personnel during the radiation detection process. When the control ball device in the embodiment of the present application detects that a person has entered the radiation detection range, it can issue an alarm and promptly shut down the radiation emitting equipment of the radiation detection.

[0041] In summary, the present invention has the following beneficial effects compared with the prior art:

[0042] (1) The utility model monitors the detection area by rotating the control ball. The monitoring panel can effectively observe whether there are people who have strayed into the detection area. When it is detected that someone has strayed into the detection area, the control ball can prevent people from being injured by giving an alarm and shutting down the radiation detection device, thereby achieving the purpose of avoiding the risk of radiation damage.

[0043] (2) The present invention increases negative pressure on the bottom of the tripod legs by arranging a leg adsorption end at the bottom of the tripod legs, so that the tripod legs can have a certain gripping force, rather than just supporting ability. Through the mutual coordination of supporting ability and gripping force, it can more effectively ensure that the posture of the control ball and the tripod legs remains stable, thereby improving the monitoring stability of the control ball.

DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0053] Example:

[0054] like Figures 1 to 5 As shown, a control ball device for a radiation monitoring area includes a control ball 1, a rotating base 2 is provided at the bottom of the control ball 1, a tripod leg 4 is provided below the rotating base 2, a monitoring panel 5 is provided on the side of the control ball 1, and a fixed connection portion 3 is provided between the rotating base 2 and the tripod leg 4. The fixed connection portion 3 is rotatably connected to the rotating base 2, and the fixed connection portion 3 and the tripod leg 4 can be locked and hinged;

[0055] The bottom end of the tripod leg 4 is provided with a leg adsorption terminal 6, and the leg adsorption terminal 6 is in contact with the ground.

[0056] In actual applications of this embodiment, the rotating base 2 is used to drive the control ball 1 to rotate, thereby increasing the monitoring coverage area of ​​this embodiment. When the monitoring panel 5 detects the risk of personnel entering the radiation detection area, it ensures the safety of personnel by alarming and shutting down radiation-related equipment to avoid personal injury. Compared with the human intervention of the prior art, the monitoring stability of this embodiment is higher and the ability to avoid injury is stronger. The control ball 1 in this embodiment is implemented using the video monitoring control ball 1 in the prior art, thereby ensuring that this embodiment can be deployed on a large scale. The rotating base 2 in this embodiment uses an electric rotating base, also using the prior art, thereby ensuring that this embodiment can be mass-produced in application.

[0057] In this embodiment, the bottom end of the tripod leg 4 provides adsorption force through the leg adsorption end 6. The adsorption force can enable the tripod leg 4 to have a certain grip on the basis of providing support. In this way, when subjected to lateral external force and upward external force, the tripod leg 4 has a certain grip ability, thereby preventing the tripod leg 4 from tipping over, thereby ensuring the stable operation of the control ball 1.

[0058] The fixed connection part 3 includes a fixed rod 31, one end of which is fixed to the control ball 1, and the other end of which is fixed to an extension rod 34. The extension rod 34 is provided with a hinge head 32 on its outer cover. The hinge head 32 is detachably fixedly connected to the extension rod 34, and an anti-slip end 35 is provided at the end of the extension rod 34.

[0059] The tripod leg 4 is hinged to the hinge head 32 , and the hinge head 32 is provided with a locking buckle 33 capable of limiting hinge rotation.

[0060] The tripod leg 4 includes a hinged end portion 41, and the hinged end portion 41 is lockably hinged to the fixed connection portion 3;

[0061] A leg fixing end 42 is fixed to the hinged end 41 , a leg telescopic rod 43 is detachably fixed to the leg fixing end 42 , and the leg adsorption end 6 is fixed to the bottom end of the leg telescopic rod 43 .

[0062] In this embodiment, by adjusting the hinge angle between the tripod legs 4 and the hinge joint 32, the height of the fixed connection part 3 can be effectively changed, thereby achieving the purpose of adjusting the height of the control ball 1. In addition to adjusting the height of the control ball 1 by the hinge angle of the tripod legs 4, the height of the control ball 1 can also be adjusted by the fixed position of the extension rod body 34 and the hinge joint 32, thereby making the height adjustment of the control ball 1 more flexible. The anti-slip end 35 can ensure that the hinge joint 32 is always located at the position of the fixed rod 31 and the extension rod body 34, thereby preventing the hinge joint 32 from falling out.

[0063] In this embodiment, after the hinge angle between the hinge head 32 and the tripod leg 4 is determined, the relative position between the hinge head 32 and the tripod leg 4 is physically limited by the locking buckle 33, thereby ensuring that the height of the control ball 1 can be stabilized. The locking buckle 33 adopts a model that can be deployed on a large scale in the existing technology.

[0064] The support leg adsorption end 6 includes a support shell 61, a negative pressure maintaining component 68 is provided in the support shell 61, a bellows 610 is provided on the negative pressure maintaining component 68, the bellows 610 is communicated with the negative pressure maintaining component 68, a pull rope 69 is provided on the bellows 610, the pull rope 69 passes through the support shell 61, and the end of the pull rope 69 is detachably fixedly connected to the tripod leg 4;

[0065] An adsorption pad 66 is provided at the bottom of the supporting shell 61 . A plurality of adsorption holes 64 are provided on the adsorption pad 66 . The negative pressure maintaining assembly 68 is in communication with the adsorption holes 64 .

[0066] In actual application of this embodiment, the bellows 610 is controlled to extend by pulling the pull rope 69, so that the air at the adsorption hole 64 is sucked out by the negative pressure maintaining component 68, and negative pressure adsorption is formed at the position of the adsorption pad 66. At the same time, the adsorption pad 66 can enhance the fit with the ground by squeezing, thereby avoiding pressure release.

[0067] The support shell 61 can provide sufficient support capacity for the support leg adsorption end 6 to achieve the purpose of supporting the upper structure. After the negative pressure maintaining component 68 forms a negative pressure state at the adsorption hole 64, it can effectively maintain the negative pressure state to avoid the loss of grip of the support leg adsorption end 6.

[0068] A partition net 63 is provided in each of the adsorption holes 64 , and the partition net 63 can completely cover the cross section of the adsorption hole 64 .

[0069] The adsorption holes 64 are evenly distributed around the center of the adsorption pad 66 .

[0070] The adsorption pad 66 is covered with a sealing inner ring 67 , and the sealing inner ring 67 is covered with a sealing outer ring 65 . The sealing outer ring 65 , the sealing inner ring 67 and the adsorption pad 66 are fixedly connected in sequence.

[0071] In this embodiment, the partition net 63 can prevent ground impurities from entering the adsorption holes 64, thereby causing damage to the negative pressure maintaining component 68 and the bellows 610. The adsorption holes 64 on the adsorption pad 66 are evenly stressed in the form of circumferentially uniform distribution, thereby ensuring that the tripod legs 4 can effectively form a resistance when subjected to external forces in all directions.

[0072] In this embodiment, the sealing outer ring 65 can provide adsorption space while improving the supporting capacity in the form of hard sealing, and the sealing inner ring 67 can improve the sealing performance in the form of flexible sealing. The squeezing of the sealing outer ring 65 and the sealing inner ring 67 with the ground can form a more stable negative pressure space, thereby ensuring the adsorption and gripping ability of the support leg adsorption end 6.

[0073] The negative pressure maintaining assembly 68 includes a negative pressure channel, a lower sealing opening 681 is provided at the bottom of the negative pressure channel, the lower sealing opening 681 is communicated with the adsorption hole 64, an expansion section 682 is provided above the lower sealing opening 681, the channel diameter of the negative pressure channel gradually increases from bottom to top in the expansion section 682, a straight pipe section 683 is provided above the expansion section 682, the channel diameter of the negative pressure channel is the same as that of the straight pipe section 683, a contraction section 684 is provided above the straight pipe section 683, the channel diameter of the negative pressure channel gradually decreases from bottom to top in the contraction section 684, and an upper sealing opening 685 is provided at the top of the negative pressure channel;

[0074] A blocking ball 62 is provided in the negative pressure channel. The diameter of the blocking ball 62 is larger than the diameter of the upper blocking opening 685 , and the diameter of the blocking ball 62 is larger than the diameter of the lower blocking opening 681 .

[0075] In this embodiment, the negative pressure in the negative pressure channel is provided by the suction of the bellows 610. The top of the negative pressure channel is provided with an upper sealing port 685. When the suction force is large, the sealing ball 62 can be prevented from falling out. The lower sealing port 681 of the negative pressure channel is used to carry the sealing ball 62 to prevent the adsorption hole 64 on the adsorption pad 66 from releasing pressure. The middle section of the negative pressure channel is provided with a larger cavity in the middle of the negative pressure channel through the setting of the expansion section 682, the straight pipe section 683 and the contraction section 684. The cavity can accommodate various impurities sucked from the ground to prevent them from entering the bellows 610 and affecting the sealing of the bellows, thereby affecting the provision of negative pressure. At the same time, it can also prevent pressure release at the adsorption hole 64 by sealing the lower sealing port 681, thereby maintaining the adsorption stability of the support leg adsorption end 6.

[0076] This embodiment provides negative pressure by pulling the bellows 610 through the pull rope 69, which can simply and effectively enhance the grip of the tripod legs 4. This structure is a purely mechanical structure and does not involve electric drive, so it can avoid providing more power supply, making construction and disassembly convenient.

[0077] The support shell 61 and the tripod leg 4 in this embodiment can be fixed in a detachable manner, so that the leg adsorption end head 6 can be easily replaced. Replacing the leg adsorption end head 6 with a new one can also avoid failure of the leg adsorption end head 6 during use.

[0078] A support rod 611 is fixed on the tripod leg 4 , and a hanging ring 612 is fixed on the end of the pull rope 69 . The hanging ring 612 can be hooked on the support rod 611 .

[0079] In this embodiment, negative pressure is supplied to the leg adsorption end 6 on the tripod leg 4 by cooperating with the pull rope 69 and the hanging ring 612. The hanging ring 612 can maintain the state of the bellows 610 through the limitation of the support rod 611, thereby avoiding pressure relief at the leg adsorption end 6.
