Description

Technical Field

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

[0002] Environmental radiation detection refers to the process of measuring and evaluating radioactive substances or radiation sources in the surrounding environment. Radiation can come from radioactive substances in nature or generated by human activities, such as nuclear power facilities, medical radiation, industrial radioactive isotopes, etc.

[0003] When testing areas containing radiation, personnel generally take samples of the soil in the environment for analysis. However, since the soil in different environments varies in height and personnel cannot enter the radiation area to manually adjust the height of the detection device, if the sampling height of the device is not appropriate, personnel need to repeatedly debug, which will make subsequent sampling work difficult to carry out quickly. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a soil radiation detection device.

[0005] The utility model is implemented by the following technical scheme: a soil radiation detection device, comprising a detection support frame, one side of the inner wall of the detection support frame is fixedly connected with an auxiliary bearing, the surface of the auxiliary bearing is fixedly connected with a main screw, both sides of the lower surface of the detection support frame are provided with adjustment components, the lower end of the detection support frame is provided with an assembly box, both sides of the inner wall of the assembly box are provided with grooves, and the inside of the groove is provided with a monitoring sensor;

[0006] The adjustment assembly comprises an upper movable column, both sides of the outer surface of the upper movable column are fixedly connected with sliding blocks, the bottom of the upper movable column is fixedly connected with an electric push rod, the bottom end of the electric push rod is fixedly connected with a lower connecting sleeve, both sides of the inner wall of the lower connecting sleeve are provided with limiting grooves, the limiting grooves are adapted to the sliding blocks, and the bottom of the lower connecting sleeve is fixedly connected with an electric wheel;

[0007] Through the above technical solution, when it is necessary to adjust the working height of the radiation detection device, the operator can start the electric push rod, and the extension and retraction of the electric push rod will directly push the upper movable column to move inside the lower connecting sleeve. Since the sliding block is adapted to the limit groove, the movement path of the upper movable column is restricted, thereby ensuring its stability and linearity during movement. As the upper movable column rises or falls, the entire detection support frame will also rise and fall synchronously, thereby accurately adjusting the working height of the detection support frame and the spiral blade shaft fixed thereon. When the spiral blade shaft is adjusted to an appropriate height, it can come into contact with the radioactive soil above the ground, thereby sampling and analyzing the soil.

[0008] As a further improvement of the above solution, a threaded sleeve is provided on the outer surface of the main screw, and reinforcing support rods are fixedly connected to both sides of the bottom of the detection support frame.

[0009] Through the above technical solution, the role of the reinforcing rod is to provide additional support and increase the stability of the detection support frame. Especially when adjusting the height or using it on uneven ground, the reinforcing rod can enhance the overall strength of the device.

[0010] As a further improvement of the above solution, an oblique support rod is provided on the outer surface of the threaded sleeve.

[0011] Through the above technical solution, the diagonal bracing rod plays a supporting role, thereby increasing the stability of the assembly box during use.

[0012] As a further improvement of the above solution, an assembly box is fixedly connected to the bottom end of the diagonal brace.

[0013] Through the above technical solution, the sensor is placed in the groove to make it closer to the object to be detected, which can improve the accuracy and sensitivity of detection and ensure the accuracy of radiation data.

[0014] As a further improvement of the above scheme, the bottom of the threaded sleeve is fixedly connected to a first motor, the inner wall of the assembly box is fixedly connected to a sampling tube via an auxiliary rod, the output end of the first motor is fixedly connected to a spiral blade shaft, and the spiral blade shaft is arranged inside the sampling tube.

[0015] Through the above technical solution, the setting of the sampling tube facilitates the transportation of radioactive soil by the spiral blade shaft inside it. The bottom end of the spiral blade shaft is tapered, so that personnel can use the first motor to make the spiral blade shaft drill holes in the radioactive soil better and faster. After drilling the soil, the spiral blade shaft can be used to evenly transport the soil to the top, thereby facilitating the monitoring sensor to detect radiation in the soil.

[0016] As a further improvement of the above scheme, the bottom end of the lower connecting sleeve is fixedly connected to an electric wheel, one side of the upper surface of the detection support frame is fixedly connected to a second motor, and one end of the main screw is fixedly connected to the output end of the second motor.

[0017] Through the above technical solution, the electric wheel is equipped with a built-in motor, which can convert electrical energy into mechanical energy to drive the vehicle or equipment to move. The electric wheel usually obtains energy for self-drive by connecting to an external power supply system. When the environmental radiation detection device needs to be moved, radiation detection can be performed at different locations through the electric wheel, which increases the flexibility of the device. At the same time, the start-up of the second motor can drive the main screw to rotate inside the auxiliary bearing, thereby adjusting the left and right position of the spiral blade shaft, and then more accurately sampling the soil.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The utility model provides an adjustment component. When it is necessary to adjust the working height of the radiation detection device, a person can push the upper movable column to move inside the lower connecting sleeve through the extension and retraction of the electric push rod. Since the sliding block is adapted to the limit groove, the movement path of the upper movable column is restricted, thereby ensuring stability and linearity during the movement. As the upper movable column rises and falls, the detection support frame will also move synchronously, thereby accurately adjusting the working height of the spiral blade shaft. When the spiral blade shaft is adjusted to an appropriate height, it can come into contact with the radiation soil above the ground, thereby sampling and analyzing the soil.

[0027] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0030] The adjustment component 4 includes an upper movable column 401, both sides of the outer surface of the upper movable column 401 are fixedly connected with sliding blocks 402, the bottom of the upper movable column 401 is fixedly connected with an electric push rod 403, the bottom end of the electric push rod 403 is fixedly connected with a lower connecting sleeve 404, both sides of the inner wall of the lower connecting sleeve 404 are provided with limiting grooves 405, the limiting grooves 405 and the sliding blocks 402 are adapted, and the bottom of the lower connecting sleeve 404 is fixedly connected with an electric wheel 13. When it is necessary to adjust the working height of the radiation detection device, the operator can start the electric push rod 403, and the extension and contraction of the electric push rod 403 will be The upper movable column 401 is directly pushed to move inside the lower connecting sleeve 404. Since the sliding block 402 is adapted to the limiting groove 405, the moving path of the upper movable column 401 is restricted, thereby ensuring its stability and linearity during movement. As the upper movable column 401 rises or falls, the entire detection support frame 1 will also rise and fall synchronously, thereby accurately adjusting the working height of the detection support frame 1 and the spiral blade shaft 12 fixed thereon. When the spiral blade shaft 12 is adjusted to an appropriate height, it can come into contact with the radiation soil above the ground, thereby sampling and analyzing the soil.

[0031] A threaded sleeve 5 is provided on the outer surface of the main screw 3, and reinforcing support rods 6 are fixedly connected to both sides of the bottom of the detection support frame 1. The function of the reinforcing support rods 6 is to provide additional support and increase the stability of the detection support frame 1, especially when adjusting the height or using it on uneven ground, the reinforcing support rods 6 can enhance the overall strength of the device.

[0032] The outer surface of the threaded sleeve 5 is provided with an oblique support rod 7 , which plays a supporting role and increases the stability of the assembly box 8 during use.

[0033] The bottom end of the diagonal support rod 7 is fixedly connected with an assembly box 8, and the monitoring sensor 9 is placed in the groove to make it closer to the object to be detected, which can improve the accuracy and sensitivity of the detection and ensure the accuracy of the radiation data.

[0034] A first motor 10 is fixedly connected to the bottom of the threaded sleeve 5, a sampling tube 11 is fixedly connected to the inner wall of the assembly box 8 through an auxiliary rod, a spiral blade shaft 12 is fixedly connected to the output end of the first motor 10, and the spiral blade shaft 12 is arranged inside the sampling tube 11. The arrangement of the sampling tube 11 facilitates the spiral blade shaft 12 to transport the radiated soil inside it. The bottom end of the spiral blade shaft 12 is conical, so that personnel can use the first motor 10 to make the spiral blade shaft 12 drill holes in the radiated soil better and faster. After drilling the soil, the spiral blade shaft 12 can evenly transport the soil to the top, thereby facilitating the monitoring sensor 9 to detect radiation in the soil.

[0035] The bottom end of the lower connecting sleeve 404 is fixedly connected with an electric wheel 13, and one side of the upper surface of the detection support frame 1 is fixedly connected with a second motor 14. One end of the main screw 3 is fixedly connected to the output end of the second motor 14. The electric wheel 13 has a built-in electric motor, which can convert electrical energy into mechanical energy to drive the vehicle or equipment to move. The electric wheel 13 usually obtains energy by connecting to an external power supply system for self-driving. Conventional products on the market can be used for the electric wheel. The structure is not described in detail here, and existing equipment can be used. When the environmental radiation detection device needs to be moved, radiation detection can be performed at different locations through the electric wheel 13, which increases the flexibility of the device. At the same time, the start-up of the second motor 14 can drive the main screw 3 to rotate inside the auxiliary bearing 2, thereby adjusting the left and right positions of the spiral blade shaft 12, and then more accurately sampling the soil.

[0036] The four electric wheels or four electric push rods in the embodiment of the present invention can be electrically connected through the same circuit, so they can maintain synchronous movement; in addition, during the actual operation of the device, remote control or a combination of wires and controllers can be used to control the electrical equipment as needed.

[0037] The implementation principle of a soil radiation detection device in the embodiment of the present application is as follows: first, the device is connected to an external power supply, which may be a power storage device such as a battery. When the working height of the radiation detection device needs to be adjusted, the operator first starts the electric push rod 403. After the electric push rod 403 is started, the upper movable column 401 can be pushed to slide along the limit groove 405 inside the lower connection sleeve 404 through its own extension or shortening movement. Since the sliding block 402 is adapted to the limit groove 405, the moving path of the upper movable column 401 is limited, thereby ensuring its stability and linearity during movement. As the upper movable column 401 rises or falls, the entire detection support frame 1 and the spiral blade shaft 12 fixed thereon will rise and fall synchronously, so that the working height of the detection support frame 1 and the spiral blade shaft 12 can be accurately adjusted to meet the needs of soil radiation detection at different depths. When the spiral blade shaft 12 is adjusted to an appropriate height, it can come into contact with the radiated soil above the ground. At this time, the operator can start the first motor 10 to rotate the spiral blade shaft 12 to drill holes in the soil. The bottom end of the spiral blade shaft 12 is tapered, which is conducive to better cutting into the soil and transporting the soil to the top. As the soil is evenly transported to the top by the spiral blade shaft 12, the monitoring sensor 9 can detect radiation in the soil. The monitoring sensor 9 can monitor the radiation level in the soil in real time and transmit the data to the background processing system for analysis. If it is necessary to fine-tune the left and right position of the spiral blade shaft 12, the operator can start the second motor 14. The second motor 14 will drive the main screw 3 to rotate inside the auxiliary bearing 2. Since the main screw 3 is threadedly matched with the threaded sleeve 5, the threaded sleeve 5 will move along the axial direction of the main screw 3, thereby driving the assembly box 8 and the spiral blade shaft 12 therein to adjust the left and right positions. This step helps to sample the soil more accurately.

[0038] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
