As shown in fig. 1 and 2, the photoelectric turntable comprises a bracket assembly 10, a detection chamber 20 rotatably connected with the bracket assembly 10, a heating deicing assembly 30 mounted on the bracket assembly 10, and a detection assembly 40 mounted in the detection chamber 20, wherein the heating deicing assembly 30 is located at a gap where the detection chamber 20 rotates relative to the bracket assembly 10 and generates heat in an electrified state.

The photoelectric turntable detects corresponding parameters of an environment or a target through a detection assembly 40, and optionally, the detection assembly 40 includes one or more of a visible light camera device, an infrared detection device, a thermal imaging camera device, a laser lighting device, and a laser ranging device. The detection assembly 40 is disposed in the detection chamber 20, and the detection chamber 20 is provided with a detection opening corresponding to the detection assembly 40 and a light-transmitting member mounted at the detection opening. The detection assembly 40 detects the external environment through the light-transmitting member to obtain the corresponding parameter. The detection assembly 40 is fixedly connected with the detection chamber 20, so that the detection assembly 40 moves synchronously with the movement of the detection chamber 20.

The probe cartridge 20 can be rotated relative to the carriage assembly 10 to adjust the probing direction of the probe assembly 40. The detection bin 20 is partially protruded to form a shaft-like structure, and the shaft-like protrusion penetrates through the heating deicing assembly 30 and is rotatably connected with the bracket assembly 10. The heating deicing assembly 30 is fixedly mounted on the carriage assembly 10 and is located at a gap where the detection bin 20 rotates relative to the carriage assembly 10, wherein the detection bin 20 can rotate relative to the heating deicing assembly 30. For example, the detection chamber 20 is provided with a rotation shaft 22, the heating and deicing assembly 30 is provided with an avoiding hole, and the rotation shaft 22 passes through the avoiding hole and is rotatably connected with the support assembly 10 so that the detection chamber 20 can rotate relative to the support assembly 10.

Wherein, there is a rotating gap between the detection bin 20 and the heating deicing assembly 30, and the heating deicing assembly 30 heats up under the condition of being electrified. The heat that heating deicing component 30 sent can be directional melts the icing of surveying storehouse 20 and bracket component 10 rotation clearance department, surveys storehouse 20 and can rotate and adjust the detection direction of surveying subassembly 40 for bracket component 10, rotates the flexibility good. The heating heat of the heating deicing assembly 30 is mainly concentrated at the rotating gap, the required heating area is small, the heat dissipation space is small, the power and the energy required by the heating deicing assembly 30 are reduced, and the power consumption is small. The rotating clearance between the detection bin 20 and the heating deicing assembly 30 is small, and after the heating deicing assembly 30 completes the deicing step, the heat preservation function can be executed, so that the required heating power is further reduced.

As shown in fig. 2 and 3, in an embodiment, the heating deicing assembly 30 includes a radiation plate 31 and a heat source element 32 fixed to the radiation plate 31, the radiation plate 31 is detachably mounted to the bracket assembly 10, and the radiation plate 31 radiates heat emitted from the heat source element 32.

The radiation plate 31 is made of a metal material having high thermal conductivity, so that heat generated from at least one heat source element 32 can be transferred to the whole radiation plate 31, thereby expanding the deicing range of the heating deicing assembly 30. For example, the radiation plate 31 is formed by processing an aluminum or aluminum alloy material by a sheet metal press process. The radiation plate 31 is installed on the bracket assembly 10 and reinforces the function of the bracket assembly 10, rapidly transfers the heat of the heat source element 32 to the whole area of the radiation plate 31, and radiates heat to the peripheral rotating mechanism matching gap and the cavity space of the bracket assembly 10. The radiation plate 31 directly heats the icing problem part of the photoelectric turntable, so that the heat loss can be effectively controlled, and the deicing efficiency is improved.

At least one heat source element 32 is fixed on the radiation plate 31, and the heat source element 32 and the radiation plate 31 are tightly combined, so that the thermal resistance between the heat source element 32 and the radiation plate 31 can be reduced, the heat transfer efficiency is effectively improved, and the loss is reduced. The heat source element 32 is configured as an electrical element that converts electrical energy into thermal energy, and optionally, the heat source element is configured as a heating tube or an infrared heating radiator. The heating pipe comprises a shell made of a metal pipe material, spiral electrothermal alloy wires and an insulating sealing element, wherein the spiral electrothermal alloy wires are uniformly distributed along the central axial direction in the shell, the insulating sealing element is sealed at the end part of the shell, so that the sealing performance of the heat source element 32 is improved, and magnesia sand with good insulating and heat conducting properties is filled and compacted in a gap between the shell and the spiral electrothermal alloy wires. Optionally, a radiant panel 31 encloses the heating tube within the rack assembly 10. Wherein, the infrared ray emitted from the infrared heating radiator can heat the ice layer between the rack assembly 10 and the detection bin 20, so that the ice layer is heated and melted.

In an alternative embodiment, the heat source element 32 is bent and distributed along the surface of the radiation plate 31 and connected with the radiation plate 31, so that the contact area between the heat source element 32 and the radiation plate 31 is increased. For example, the outer shell of the heating tube is welded to the radiant panel 31, and may be formed by a full-length welding process or a section welding process. The input voltage and the power density of the heating deicing assembly 30 can be freely combined with a power supply and a matching circuit, and various electrical properties such as surface insulation, voltage resistance, breakdown resistance and the like can be designed according to different technical requirements. Optionally, the heating deicing assembly 30 is in contact with the ice layer through the radiation plate 31, and the heating pipe is arranged in the bracket assembly 10, so that additional protection structures such as water resistance and electric leakage prevention are avoided, the deicing requirement can be quickly and efficiently met, and the free rotation function of the photoelectric turntable in various low-temperature harsh environments is ensured.

The heat source element 32 is bent into a bent tube structure to enlarge the heating area of the heat source element 32. For example, the heat source element 32 is bent to approximate a U-shaped structure and a Z-shaped structure; alternatively, the heat source element 32 is a continuous bent structure; alternatively, the heat source element 32 includes a first curved portion, a second curved portion, and a connecting portion connecting the first curved portion and the second curved portion, wherein the first curved portion and the second curved portion are approximately in a C-shaped structure, or the first curved portion and the second curved portion are approximately in a concentric arc structure, and of course, the first curved portion and/or the second curved portion may be partially curved to adapt to the installation requirements of the radiant panel 31.

In an embodiment, the radiation plate 31 is provided with a relief portion 311, and the heat source element 32 is distributed along the surface of the radiation plate 31 in a bent manner and is bent to avoid the relief portion 311. The avoiding part 311 is arranged in a notch or a hole structure which avoids the detection bin 20 and the bracket component 10, and the heat source piece 32 is bent and arranged to avoid the avoiding part 311 and enlarge the contact area between the heat source piece 32 and the radiation plate 31. The heat radiated by the radiation plate 31 can effectively cover the inner cavity and the rotating gap of the photoelectric turntable, and the requirement of quick deicing in the low-temperature environment of the whole machine is met.

In an alternative embodiment, two or more heat source elements 32 are provided, and the two or more heat source elements 32 are symmetrically distributed on the radiation plate 31. The heat source elements 32 are symmetrically arranged on the radiation plate 31, so that the total length of the single heat source element 32 is shortened, and the cost of the heat source element 32 is reduced. The radiation plate 31 enables the heat source to be evenly distributed under the heating of the heat source piece 32, the melting efficiency of the condensed ice layer is high, and the ice melting balance is good. For example, the avoiding portion 311 includes a circular hole region penetrating through the radiation plate 31, and the two heat source members 32 are bent and symmetrically distributed on the radiation plate 31 and surround the avoiding region. Alternatively, the avoidance portion 311 includes an avoidance gap opened to the edge of the radiation plate 31, and the two heat source members 32 are symmetrically distributed on both sides of the avoidance gap.

As shown in fig. 2 and 4, in an embodiment, the rack assembly 10 includes a pitch rack 11, a pitch driving device 15 mounted on the pitch rack 11, and a torsion testing device 13, and the heating deicing assembly 30 is attached to the pitch rack 11. The detecting cabin 20 is connected to the pitching driving device 15, and the torsion testing device 13 is used for detecting torsion generated when the pitching driving device 15 drives the detecting cabin 20 to rotate. When the torque parameter of the torque testing device 13 is greater than a standard value, the heating deicing assembly 30 is powered on to generate heat.

The pitch driving device 15 is installed in the pitch bracket 11 and connected to the detection chamber 20, so that the detection chamber 20 is connected to the pitch bracket 11 and can rotate relative to the pitch bracket 11. Wherein, the pitching driving device 15 drives the detection cabin 20 to rotate relative to the pitching supporting frame 11 according to the control signal, so as to adjust the detection direction and angle of the detection component 40. The torsion testing device 13 is connected to the pitching driving device 15 and the rotating shaft 22 of the detecting chamber 20, so that the torque force generated by the pitching driving device 15 driving the detecting chamber 20 to rotate can be detected by the torsion testing device 13. When the icing is not formed or the icing amount between the detection bin 20 and the heating deicing assembly 30 is small, the torsion testing device 13 detects that the torque force of the pitching driving device 15 driving the detection bin 20 to rotate is a first torque value, and the first torque value is within a standard value range of normal operation of the photoelectric turntable, so that the heating deicing assembly 30 is not electrified to generate heat. When ice is condensed and connected in a rotating gap between the detection bin 20 and the heating deicing assembly 30, the torsion testing device 13 detects that the torsion parameter of the pitching driving device 15 driving the detection bin 20 to rotate is a second torque value, and the second torque value exceeds a standard value interval of normal operation of the photoelectric turntable, so that the heating deicing assembly 30 is electrified to generate heat. The heating deicing assembly 30 is powered on to generate heat or is in a dormant state according to the detection result of the torsion testing device 13, so as to save energy.

The energization triggering mechanism of the heating deicing assembly 30 can also adopt other detection modes besides the detection by the torsion testing device 13. For example, by detecting ambient temperature as a power-on trigger for heating the de-icing assembly 30; the distance of the rotating gap between the detection bin 20 and the bracket assembly 10 is detected by means of infrared induction and the like as an electrifying trigger mechanism for heating the deicing assembly 30. In an optional embodiment, the optoelectronic turntable further comprises a temperature detection device for detecting an ambient temperature; when the ambient temperature is less than or equal to zero degrees, the heating deicing assembly 30 is energized to generate heat. The temperature detecting means may be a temperature detecting means mounted on the surface of the bracket assembly 10, for example, the temperature detecting means is provided as a temperature sensor. When the ambient temperature is less than zero, water easily condenses into ice at the rotating gap. The heating de-icing assembly 30 heats or maintains the temperature when the ambient temperature reaches zero to maintain rotational stability of the detection chamber 20.

As shown in fig. 5 and 6, when the photoelectric turntable cannot rotate due to icing, the heating deicing assembly 30 is activated to convert electric energy into heat energy, and the ice layer condensed at the rotating gap is converted into liquid water under the action of the heat energy of the heating deicing assembly 30. Wherein the heat that heats the deicing assembly 30 is transferred to the ice layer from two ways: (1) the heat source element 32 heats the ice layer by radiation, mainly concentrated on the middle upper part of the rotating gap, and the hot air flows upwards and the water flows downwards. (2) When the middle upper ice layer melts, the ice-water mixture will again accumulate at the bottom of the pitching frame 11. The heat generated by the heat source 32 heats the whole fan-shaped radiant panel 31 in a heat conduction manner, so that the temperature of the ice layer at the middle and lower parts reaches above the freezing point, and the deicing effect of the whole machine is ensured. After the heating deicing assembly 30 is activated for a period of time, the rotation time of the turntable in each direction is tested by sensors inside the product. When the operation of the photoelectric turntable reaches a set value, the heating deicing assembly 30 is closed or enters a heat preservation mode.

Optionally, the heated de-icing assembly 30 is configured to have a heating mode in which the supply rate is increased and the heating temperature is high so that ice at the rotating gap can be rapidly melted, and a keep warm mode. When the heating deicing assembly 30 is heated for a preset time, the heating deicing assembly enters a heat preservation mode, so that water flowing into the rotating gap cannot be condensed into ice, the power consumption of the photoelectric turntable can be reduced, and the energy-saving effect is good.
