Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Referring to fig. 1-4, a laser radar assembly of an underwater nuclear radiation detector comprises a laser radar 2 arranged at the lower end position in a shell 1, and a window 3 for the laser radar to transmit is arranged at the lower end of the shell 1.
It should be noted that conventional nuclear radiation detectors have substantially utilized the interior space of the housing; the structure of the device is longer than the conventional structure to form the installation space of the laser radar 2.
Wherein, the shell 1 is of a hollow cylindrical structure, and the inside of the shell is provided with a mounting cavity.
Further, the shell 1 is in a multi-section assembly form; for example, the shell 1 is in a two-section or three-section assembly form; of course, more sections may be provided if necessary.
In the drawings of the present specification, a three-section housing 1 is exemplified.
Therefore, under the multi-section mode, each component in the shell 1 is respectively arranged in different sections, and the operation such as layout, installation and maintenance is facilitated.
Correspondingly, the laser radar 2 is arranged in the lowest section, does not interfere with the nuclear radiation detector, and the positions of the laser radar 2 and the nuclear radiation detector are independent.
It should be noted that the nuclear radiation detector may be mounted at the upper or middle section of the housing 1; the structure is set in the prior art, and the installation space in the section is adapted to the installation space, and is not described in detail herein.
What needs to be stated is:
the shell 1 can also be arranged into a whole root structure, but correspondingly, the installation difficulty of the internal components can be increased, and the later maintenance is not facilitated; of course, the structural form of the whole root can be selected and set according to actual requirements; in this state, an opening is provided at one or both ends of the housing 1 to mount the assembly inward.
In some embodiments, mutually adapted threads are provided between the sections of the housing 1.
As shown in fig. 1, the assembly can be conveniently performed; and according to different specifications and environmental requirements, different lengths and different sections can be set.
In some embodiments, a rubber sealing ring 4 is sleeved at the joint of the shell 1; significantly enhancing the tightness and protection of the threads.
Further, the outer side of the rubber sealing ring 4 is provided with anti-skid patterns so as to facilitate operation; and the device is more convenient to hold by hand.
It should be noted that a sealing gasket is correspondingly arranged at the thread abutting position.
In some embodiments, a limit structure 5 matched with the inner cavity of the shell 1 is arranged above the laser radar 2; to firmly mount the lidar 2.
For example, in some embodiments:
the limit structure is a threaded column, and the inner cavity of the shell 1 is provided with threads matched with the threaded column.
As shown in fig. 3, the assembly is performed by threads; in the installed configuration, the threaded post may be fully submerged in the cavity of the housing 1 of the lowermost section, or may extend a portion thereof.
Furthermore, in order to facilitate the rotation operation of the threaded column, a slotted boss is arranged at the end part of the threaded column, and the threaded column can be screwed in and taken out in an auxiliary manner through tools such as a screwdriver.
It should be noted that the outer diameter of the threaded post is larger than the outer diameter of the lidar 2; in the mounted state, the axis of the threaded post coincides with the axis of the housing 1.
In addition, supplementary notes are:
the limit structure 5 of the lidar 2 is not limited to the thread form; fastening, screws and other fixing forms can be adopted.
In some embodiments, a lithium battery is disposed within the housing 1; correspondingly, a wire holder 6 is arranged at the upper end of the laser radar 2.
The lithium battery is preferably arranged in the middle of the housing 1.
In addition, a communication module connected with the laser radar 2 is also arranged in the shell 1; the communication module can be shared with the nuclear radiation detector, and can be a wired or wireless communication module.
The modules are all of the prior art, and no further description is given here
In some embodiments, the lower end of the housing 1 is provided with a counterweight 7; so that the whole device is kept in a vertical form in the water body.
Preferably, the weight 7 is screw-fitted to the outside of the housing 1.
It will be appreciated that external threads are provided on the outside of the housing 1 to fit the weights 7.
In some embodiments, the window 3 is a transparent body inlaid in the lower end of the housing 1.
Wherein, the laser radar can be made of transparent plastic, glass or other crystals and materials which do not influence the laser radar; the tightness in the installation state is ensured.
When the utility model is used, the shell 1 is assembled and sealed; the device is placed in the body of water and under the action of gravity the lidar 2 detects the distance between it and the seabed.
The utility model is suitable for almost all detectors needing radar, and provides functions of positioning, depth detection and the like for the detectors so as to meet the requirements. And, if necessary, can also replace the laser radar with other positioning, range finding assemblies; accordingly, it is sufficient to install it at a position inside the lower end of the housing 1.
In the utility model, the shell 1 is in a multi-section assembly form, and each component is respectively arranged in different sections, thereby being beneficial to the operations of layout, installation, maintenance and the like; the laser radar 2 is arranged in the lowest section and does not interfere with the nuclear radiation detector, and the positions of the laser radar 2 and the nuclear radiation detector are independent; the screw thread is arranged between the joints, so that the assembly can be conveniently carried out, and different lengths and different joint numbers can be set according to different specifications and environmental requirements; the rubber sealing ring 4 is sleeved, so that the tightness is obviously enhanced, and the threads are protected; the counterweight 7 is arranged so that the whole device is kept in a vertical form in the water body.
