Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring equipment technology, and in particular to an environmental monitoring device for nuclear power plants. Background Technology

[0002] Environmental monitoring equipment for nuclear power plants is a series of instruments specifically designed to monitor the levels of radioactive materials and related parameters in the environment surrounding the nuclear power plant in real time. It can continuously detect radiation dose rates and specific nuclide concentrations in the air, water, and soil, and supports remote data transmission and early warning functions.

[0003] To prevent damage to the bottom of nuclear power plant environmental monitoring equipment, such as radiation monitors, a rigid support structure is generally used at the bottom of the equipment. The support supports the equipment and prevents it from directly contacting the ground.

[0004] In related technologies, due to the existence of uneven areas at nuclear power plant sites, traditional three- or four-point rigid support structures cannot adapt to the ground and cannot compensate for ground height differences. This results in a certain degree of tilt after the equipment is placed, causing the equipment to tilt or sway. Consequently, the environmental monitoring equipment cannot maintain a horizontal state, which seriously affects the accuracy of radiation monitoring data. Utility Model Content

[0005] To address the problem that current environmental monitoring equipment's bottom support feet cannot adapt to uneven ground, which can easily lead to the equipment tilting or shaking, this utility model provides an environmental monitoring device for nuclear power plants.

[0006] The present invention provides an environmental monitoring device for nuclear power plants, which adopts the following technical solution: An environmental monitoring device for a nuclear power plant, comprising: The monitoring device body has a base fixed to its bottom, an installation cavity inside the base, and a height adjustment mechanism at the top of the installation cavity. An adaptive support mechanism is used to adaptively support the monitoring device body, and the adaptive support mechanism is connected to the bottom of the height adjustment mechanism. The adaptive support mechanism includes a docking seat, a balance bar, an abutment plate, a slide groove, and a support rod. The docking seat is fixed at the bottom center of the height adjustment mechanism. The center of the balance bar is rotatably connected to the docking seat. Two abutment plates are provided, and the two abutment plates are symmetrically arranged on both sides of the balance bar. The sliding groove is provided through the abutment plate. The balance bar slides against the sliding groove. Inclined surfaces are provided on both sides of the abutment plate. A through hole is provided through the bottom of the base. The support rod is slidably engaged in the through hole. One end of the support rod slides against the inclined surface, and the other end is located at the bottom of the base.

[0007] By adopting the above technical solution, utilizing the height adjustment mechanism and the adaptive support mechanism, the height adjustment mechanism supports the entire adaptive support mechanism and appropriately adjusts its overall height. Symmetrically arranged abutment plates adaptively slide on the balance bar, while the support rods adaptively slide on the inclined surfaces of the abutment plates. Through the inclined surface contact, horizontal displacement is converted into vertical lifting and lowering of the support rods, achieving independent adaptive fine-tuning of the height at the four corners of the equipment and forming an adaptive balance structure. This allows the support rods at the bottom of the equipment to adaptively adjust when facing uneven ground, ensuring the overall level of the monitoring equipment and preventing swaying or tilting. This increases the overall stability of the monitoring equipment and provides hardware-level assurance for the accuracy of the monitoring data.

[0008] Optionally, the adaptive support mechanism further includes a positioning disk and a spring. The positioning disk is coaxially fixed on the support rod and located inside the mounting cavity. The spring is sleeved on the support rod, with one end of the spring abutting against the positioning disk and the other end abutting against the base.

[0009] By adopting the above technical solution, the spring force is used to push the support rod, thereby enabling the support rod to quickly return to its original position.

[0010] Optionally, the height adjustment mechanism includes a fixed plate, a mounting base, a linkage base, a first linkage rod, a second linkage rod, and a support plate. The fixed plate and the mounting base are both fixed to the top of the mounting cavity. Multiple fixed plates are provided. The linkage base is slidably engaged in the mounting base. One end of the first linkage rod and the second linkage rod are rotatably connected to each other. The other end of the first linkage rod is rotatably connected to the fixed plate. The other end of the second linkage rod is rotatably connected to the support plate. The support plate is located at the bottom of the linkage base, and the docking seat is fixed on the support plate.

[0011] By adopting the above technical solution, the vertical position of the base and the adaptive support mechanism as a whole inside the base can be quickly adjusted by the linkage of the first linkage rod and the second linkage rod.

[0012] Optionally, two sets of linkage components are symmetrically arranged, consisting of the first linkage rod and the second linkage rod, and two sets of linkage components are arranged in parallel on one side, with a crossbar rotatably connected at the connection point of the first linkage rod and the second linkage rod of the two sets of linkage components.

[0013] By adopting the above technical solution and utilizing symmetrically arranged linkage rods, the base can be stably driven, thus avoiding any tilting.

[0014] Optionally, the height adjustment mechanism further includes a rack, a gear, a transmission rod, and a lead screw. The rack is fixed to one side of the linkage seat. The gear is coaxially fixed to the first linkage rod and the rotating connection end of the fixed plate, and the gear meshes with the rack. The transmission rod is rotatably connected to the support plate. The lead screw is coaxially fixed to one end of the transmission rod. A threaded hole is provided through the center of one side of the support plate, and the lead screw is threaded into the threaded hole.

[0015] By adopting the above technical solution, the transmission rod drives the lead screw to rotate, thereby causing the base to mesh and move. The sliding of the base then drives the rack to move, and the rack causes the gears to mesh and move, thereby driving the first linkage rod to rotate, thus achieving rapid adjustment of the angle between the first linkage rod and the second linkage rod.

[0016] Optionally, a foot is fixed to one end of the support rod located outside the base, and the foot has a spherical structure.

[0017] By adopting the above technical solution and utilizing the spherical base, the base can make stable contact with the ground, thereby further improving the overall stability of the device.

[0018] In summary, this utility model has at least one of the following beneficial technical effects: By utilizing a height adjustment mechanism and an adaptive support mechanism, the height adjustment mechanism supports the entire adaptive support mechanism and allows for appropriate height adjustment. Symmetrically arranged abutment plates adaptively slide on the balance bar, while the support rods adaptively slide on the inclined surfaces of the abutment plates. This inclined surface contact converts horizontal displacement into vertical lifting and lowering of the support rods, enabling independent adaptive fine-tuning of the height at the four corners of the equipment and forming an adaptive balance structure. This allows the support rods at the bottom of the equipment to adaptively adjust when facing uneven ground, ensuring the overall level of the monitoring equipment and preventing swaying or tilting. This increases the overall stability of the monitoring equipment and provides hardware-level assurance for the accuracy of the monitoring data. Attached Figure Description

[0027] Reference Figure 1 and Figure 2 An environmental monitoring device for a nuclear power plant includes a monitoring device body 1, a base 2, a height adjustment mechanism 3, and an adaptive support mechanism 4. The base 2 is fixed to the bottom of the monitoring device body 1. An installation cavity is provided inside the base 2. A height adjustment mechanism 3 is provided at the top of the installation cavity. The adaptive support mechanism 4, which is used to adaptively support the monitoring device body 1, is connected to the bottom of the height adjustment mechanism 3. The adaptive support mechanism 4 includes a docking seat 41, a balance bar 42, an abutment plate 43, a sliding groove 44, and a support rod 45.

[0028] In this embodiment, the height adjustment mechanism 3 and the adaptive support mechanism 4 are used to support the adaptive support mechanism 4 as a whole and adjust its overall height appropriately. The symmetrically arranged abutment plates 43 adaptively slide on the balance bar 42, while the support rod 45 adaptively slides on the inclined surface of the abutment plate 43. The horizontal displacement is converted into the vertical lifting and lowering of the support rod 45 through the inclined surface contact, realizing independent adaptive fine-tuning of the height of the four corners of the device and forming an adaptive balance structure. When the device faces uneven ground, the support rod 45 at the bottom can adaptively adjust, thereby ensuring that the monitoring device body 1 is in a horizontal state. At the same time, it avoids the monitoring device body 1 from shaking or tilting, increases the overall stability of the monitoring device body 1, and provides hardware-level protection for the accuracy of the monitoring data of the monitoring device body 1.

[0029] Specifically, the docking seat 41 is fixed at the bottom center of the height adjustment mechanism 3, the center of the balance bar 42 is rotatably connected to the docking seat 41, two abutment plates 43 are provided, and the two abutment plates 43 are symmetrically arranged on both sides of the balance bar 42, the sliding groove 44 is provided through the abutment plate 43, the balance bar 42 slides against the sliding groove 44, and there are inclined surfaces on both sides of the abutment plate 43. The bottom of the base 2 is provided with a through hole, the support rod 45 is slidably engaged in the through hole, and one end of the support rod 45 slides against the inclined surface, and the other end is located at the bottom of the base 2.

[0030] Reference Figure 3 In this embodiment of the utility model, the adaptive support mechanism 4 further includes a positioning disk 46 and a spring 47. The positioning disk 46 is coaxially fixed on the support rod 45 and located in the mounting cavity. The spring 47 is sleeved on the support rod 45. One end of the spring 47 abuts against the positioning disk 46 and the other end abuts against the base 2. The elastic force of the spring 47 pushes the support rod 45, thereby enabling the support rod 45 to quickly return to its original position.

[0031] Reference Figure 4 Specifically, in this embodiment of the present invention, the height adjustment mechanism 3 includes a fixed plate 31, a card seat 32, a linkage seat 33, a first linkage rod 34, a second linkage rod 35, and a support plate 36. The linkage of the first linkage rod 34 and the second linkage rod 35 enables rapid adjustment of the vertical position of the support plate 36 and the entire adaptive support mechanism 4 within the base 2. In this embodiment of the utility model, the fixing plate 31 and the card seat 32 are both fixed on the top of the mounting cavity. Multiple fixing plates 31 are provided. The linkage seat 33 is slidably engaged in the card seat 32. One end of the first linkage rod 34 and the second linkage rod 35 are rotatably connected to each other. The other end of the first linkage rod 34 is rotatably connected to the fixing plate 31. The other end of the second linkage rod 35 is rotatably connected to the support plate 36. The support plate 36 is provided at the bottom of the linkage seat 33, and the docking seat 41 is fixed on the support plate 36.

[0032] Specifically, two sets of linkage components, consisting of the first linkage rod 34 and the second linkage rod 35, are symmetrically arranged, and two sets of linkage components are arranged parallel to one side. A crossbar is rotatably connected at the connection point of the first linkage rod 34 and the second linkage rod 35 of the two sets of linkage components. By using the symmetrically arranged linkage rods, the support plate 36 can be stably transmitted, thus avoiding the occurrence of skewing.

[0033] In this embodiment of the utility model, the height adjustment mechanism 3 further includes a rack 37, a gear 38, a transmission rod 39, and a lead screw 310. The rack 37 is fixed on one side of the linkage seat 33. The gear 38 is coaxially fixed on the first linkage rod 34 and the rotating connection end of the fixed plate 31, and the gear 38 meshes with the rack 37. The transmission rod 39 is rotatably connected to the base 2. The lead screw 310 is coaxially fixed on one end of the transmission rod 39. A screw hole is provided through the center of one side of the support plate 36, and the lead screw 310 is threaded into the screw hole.

[0034] The transmission rod 39 drives the lead screw 310 to rotate, which in turn causes the support plate 36 to mesh and move. The sliding of the support plate 36 then drives the rack 37 to move, and the rack 37 causes the gear 38 to mesh and move, which in turn drives the first linkage rod 34 to rotate, thus achieving rapid adjustment of the angle between the first linkage rod 34 and the second linkage rod 35.

[0035] A foot 48 is fixed to one end of the support rod 45 outside the base 2. The foot 48 has a spherical structure. The spherical structure of the foot 48 enables it to make stable contact with the ground, thereby further improving the overall stability of the device.

[0036] The implementation principle of an environmental monitoring device for a nuclear power plant according to an embodiment of this utility model is as follows: When the device is placed on the ground, the base 48 contacts the ground and pushes the support rod 45 to slide. One end of the support rod 45 slides on the inclined surface of the abutment plate 43. At the same time, the balance rod 42 slides in the sliding groove 44, and drives multiple support rods 45 to slide adaptively and maintain a balanced state. When it is necessary to adjust the height of the support rod 45, the transmission rod 39 is rotated to drive the lead screw 310 to rotate, so that the lead screw 310 is threaded in the support plate 36 and drives the linkage seat 33 to slide. The linkage seat 33 drives the rack 37 to move and makes the gear 38 mesh and link. At this time, the gear 38 synchronously drives the first linkage rod 34 to rotate, so that the first linkage rod 34 and the second linkage rod 35 are linked synchronously, thereby realizing the adjustment of the height of the support plate 36 and the adaptive support mechanism 4 as a whole inside the base 2.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
