Technical Field

[0001] The utility model relates to a detector of an airborne aviation gamma energy spectrum measurement system for an unmanned aerial vehicle, in particular to an installation box for a CeBr3 detector of an unmanned aerial vehicle. Background Art

[0002] Aviation gamma energy spectrum measurement is to integrate a gamma energy spectrum measurement system on an aviation mobile platform to measure the gamma ray energy, intensity and their distribution of natural or artificial radionuclides in surface rocks, soils and the atmosphere. At present, with the continuous development of unmanned aerial vehicle technology, unmanned aerial vehicles are gradually used for small-scale and high-precision aviation gamma energy spectrum measurement, and the CeBr3 crystal is a commonly used detection crystal.

[0003] In addition to the CeBr3 crystal, the detector also includes electronic devices such as a digital multi-channel energy spectrum analyzer. In the existing detector, the detection crystal and the electronic devices are arranged in the same space. When the electronic devices are running, heat will be generated, and the generated heat will directly cause the temperature around the detection crystal to rise, and the temperature rise will affect the performance of the CeBr3 crystal, resulting in measurement errors and affecting the accuracy of aviation gamma energy spectrum measurement. Content of the Utility Model

[0004] The purpose of the utility model is to provide an installation box for a CeBr3 detector of an unmanned aerial vehicle to solve the problem that the performance of the CeBr3 crystal is affected by the temperature rise inside the existing detector, resulting in measurement errors.

[0005] The utility model is realized as follows: An installation box for a CeBr3 detector of an unmanned aerial vehicle includes a box body with an open upper end, a top cover is arranged on the top of the box body, a partition board is arranged inside the box body, and the partition board divides the space inside the box body into an electronic device space and a detection crystal space. A number of detection crystals are arranged in the detection crystal space. A wire passing hole is opened on the partition board. Heat dissipation fins are arranged on the bottom surface of the electronic device space. A number of digital multi-channel energy spectrum analyzers are arranged on the upper surface of the heat dissipation fins. Ventilation holes are opened on two opposite side walls of the electronic device space, and heat dissipation fans are arranged at the ventilation holes. A number of installation holes for installing wiring sockets are arranged on the side wall of the electronic device space.

[0006] As a further improvement of the installation box for a CeBr3 detector of the utility model, a shock-absorbing filler is arranged in the detection crystal space. The shock-absorbing filler includes a main body layer and a top layer located above the main body layer. A number of accommodation cavities for placing detection crystals are opened on the main body layer.

[0007] As a further improvement of the CeBr3 detector installation box of the present utility model for unmanned aerial vehicles, connectors are provided on both sides of the bottom of the box body. The cross-section of the connector is T-shaped, and the two wing plates of the connector are fixedly connected to the corners of the bottom of the box body in a fitting manner. Fixing connection holes for connecting to the unmanned aerial vehicle are provided on the extended wing plates of the connector.

[0008] As a further improvement of the CeBr3 detector installation box of the present utility model for unmanned aerial vehicles, a network switch and a power module are also provided on the side wall of the electronic device space.

[0009] As a further improvement of the CeBr3 detector installation box of the present utility model for unmanned aerial vehicles, the air direction of one of the heat dissipation fans is from outside the box to inside the box, and the air direction of the other heat dissipation fan is from inside the box to outside the box.

[0010] As a further improvement of the CeBr3 detector installation box of the present utility model for unmanned aerial vehicles, the fin direction of the heat dissipation fins is consistent with the setting direction of the two heat dissipation fans.

[0011] As a further improvement of the CeBr3 detector installation box of the present utility model for unmanned aerial vehicles, the top cover is fixed to the top of the box body by bolts.

[0012] The interior of the box body of the present utility model is divided into two spaces, which are respectively used for placing electronic devices and detection crystals. The heat generated by the electronic devices during operation is discharged outside the box body in a timely manner through the heat dissipation fans, which can prevent the temperature inside the electronic device space from being too high. Moreover, the partition can prevent the heat in the electronic device space from diffusing to the detection crystal space and will not cause the temperature in the detection crystal space to rise. Thus, the influence of the heat generated by the electronic devices on the detection crystals is avoided, which is beneficial to reducing measurement errors and ensuring the accuracy of airborne gamma energy spectrum measurement.

[0013] A shock-absorbing filler is provided in the detection crystal space, and the detection crystal is placed in the shock-absorbing filler. On the one hand, the shock-absorbing filler plays a role in buffering and shock-absorbing the detection crystal; on the other hand, the shock-absorbing filler itself plays a certain heat-insulating role. In addition, the shock-absorbing filler basically completely fills the detection crystal space, reducing the gas convection between the electronic device space and the detection crystal space through the wire passing holes, and further reducing the influence of the heat generated by the electronic devices on the detection crystals.

[0014] The box body of the present utility model is connected to the unmanned aerial vehicle through connectors, and has high connection strength and connection stability. Description of the Drawings

Specific embodiments

[0020] The specific embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0021] As Figure 1 , Figure 2 Figure 3 and Figure 4 shown, the present utility model is an installation box for a drone CeBr3 detector, and components such as a detection crystal 7 and a digital multi-channel energy spectrum analyzer 15 are installed inside the box body 1.

[0022] The box body 1 has a rectangular structure. The upper end of the box body 1 is open and is provided with a top cover 2. The upper port of the box body 1 is sealed by the top cover 2, and it is convenient for the installation and disassembly of components after opening the top cover 2.

[0023] Among them, the top cover 2 is connected to the box body 1 by bolts. The top cover 2 can be stably fixed on the box body 1 by bolts, and it is convenient to open the top cover 2.

[0024] A partition board 4 is horizontally arranged in the middle of the box body 1. The partition board 4 divides the inner cavity of the box body 1 into two parts, namely an electronic device space 5 and a detection crystal space 6. The detection crystal space 6 is used to place the detection crystal 7, and the electronic device space 5 is used to install various other components such as a digital multi-channel energy spectrum analyzer 15. The partition board 4 can prevent the heat in the electronic device space 5 from diffusing to the detection crystal space 6.

[0025] A wire threading hole 4-1 is opened on the partition board 4. The cable connected to the detection crystal 7 enters the electronic device space 5 through the wire threading hole 4-1 on the partition board 4 and is connected to the digital multi-channel energy spectrum analyzer 15, etc.

[0026] To improve the heat dissipation capacity of the electronic device space 5, ventilation holes 11 are opened on two opposite side walls of the electronic device space 5, and fan mounting holes 9 are opened at the ventilation holes 11. A cooling fan (not shown in the figure) is installed on the inner wall of the electronic device space 5 through the fan mounting holes 9, and the cooling fan faces the ventilation holes 11.

[0027] Two cooling fans are arranged oppositely, and the air flow direction of one of the cooling fans is from outside the box body 1 to inside the box body 1, while the air flow direction of the other cooling fan is from inside the box body 1 to outside the box body 1. After the two fans are started, the external air enters the electronic device space 5 from one side and then is discharged from the other side, thereby taking away the heat in the electronic device space 5 and realizing efficient heat dissipation of the electronic device space 5.

[0028] Furthermore, heat dissipation fins 12 are arranged on the bottom surface of the electronic device space 5. According to needs, a number of digital multi-channel energy spectrum analyzers 15 are installed on the heat dissipation fins 12. The air flow passes through the digital multi-channel energy spectrum analyzers 15, taking away the heat generated by the digital multi-channel energy spectrum analyzers 15 and discharging it.

[0029] Preferably, the direction of the fins of the heat dissipation fins 12 is consistent with the air flow direction formed by the two cooling fans. The air flow passes through the heat dissipation fins 12 to take away the heat of the heat dissipation fins 12, and further dissipates the heat of the digital multi-channel energy spectrum analyzers 15.

[0030] The top surface of the heat dissipation fins 12 is a plane, and a number of holes for fixedly installing the digital multi-channel energy spectrum analyzers 15 are opened on the top surface of the heat dissipation fins 12.

[0031] A network switch 14, a power module 13, etc. are also arranged on the side wall of the electronic device space 5. The power module 13 is used to provide power for the cooling fan, etc.

[0032] A number of mounting holes 9 for installing the wiring sockets 10 are opened on the front side of the box body 1. The devices inside the box body 1 are connected to the wiring sockets 10 according to needs, and are connected to external power supplies, controllers, etc. through the wiring sockets 10. The structure of the detector of the airborne aviation gamma energy spectrum measurement system belongs to the existing mature technology, and its composition and wiring, etc. will not be elaborated here.

[0033] For the detection crystal space 6, a shock-absorbing filler 8 is filled in the detection crystal space 6. The shock-absorbing filler 8 completely fills the inner cavity of the detection crystal space 6. At the same time, a receiving cavity for placing the detection crystal 7 is opened in the shock-absorbing filler 8. The detection crystal 7 is placed in the receiving cavity, and the detection crystal 7 is supported by the shock-absorbing filler 8. When the box body 1 vibrates, the shock-absorbing filler 8 can relieve and eliminate the vibration, ensuring the stable operation of the detection crystal 7.

[0034] On the one hand, the shock-absorbing filler 8 plays a role in buffering and shock-absorbing the detection crystal 7; on the other hand, the shock-absorbing filler 8 itself plays a certain heat-insulating role. In addition, the shock-absorbing filler 8 substantially completely fills the detection crystal space 6, reducing the gas convection between the electronic device space 5 and the detection crystal space 6 through the wire passing holes, and further reducing the influence of the heat generated by the electronic device on the detection crystal 7.

[0035] Among them, the shock-absorbing filler 8 includes a main body layer and a top layer located above the main body layer. The thickness of the top layer is less than that of the main body layer. The accommodation cavity is opened on the main body layer. After the detection crystal 7 is placed in the accommodation cavity, the top layer is placed above to cover the top surface of the main body layer, and the detection crystal 7 is completely wrapped inside the shock-absorbing material.

[0036] The material of the shock-absorbing filler 8 can be materials such as foam, plastic foam, sponge, etc.

[0037] Connectors 3 are provided on both sides of the bottom of the box body 1. The connectors 3 are strip-shaped and the length direction of the connectors 3 is the same as the length direction of the box body 1. The cross-section of the connector 3 is T-shaped. The two wing plates of the connector 3 are fixedly connected to the corners of the bottom of the box body 1. Fixing connection holes for connecting with the drone are opened on the protruding wing plates of the connector 3. There are several fixing connection holes, and the corresponding fixing connection holes are selected for connection according to needs.

[0038] The T-shaped connector 3 is connected to the box body 1 by bolts, anchor bolts, etc., which can improve the overall structural strength of the box body 1, and a stable and firm connection can be achieved between the connector 3 and the connection frame of the drone.
