In this embodiment, the baffle chamber 12 is a closed space, and the baffle chamber 12 can be filled with liquid or gas, wherein the liquid is, for example, water, and the gas is, for example, air or nitrogen, etc., and the first light-transmitting area 101 and the second light-transmitting area 102 are both made of transparent materials, such as glass or plastic, which can achieve light transmission.

[0033] The horizontal detection device of the present invention is provided with a blocking structure 121 in the blocking chamber 12, and a first light-transmitting area 101 is provided between the light source chamber 11 and the blocking chamber 12, and a second light-transmitting area 102 is provided between the blocking chamber 12 and the indicating chamber 13. When the horizontal detection device is in a horizontal state, the blocking structure 121 covers the first light-transmitting area 101 and the second light-transmitting area 102, and the second light source 133 is in an extinguished state. When the horizontal detection device is tilted, the blocking structure 121 cannot completely cover the first light-transmitting area 101 and the second light-transmitting area 102, and the light of the first light source 112 in the light source chamber 11 passes through the first light-transmitting area 101 and the second light-transmitting area 102 into the indicating chamber 13, and the second light source 133 in the indicating chamber 13 is lit, so that it can be determined that the horizontal detection device is in a tilted state, thereby determining that the detection surface of the engineering machinery using the horizontal detection device is in a horizontal state or a tilted state. The horizontal detection device is not only simple in structure, convenient in use, and low in cost, but also easy in installation and maintenance.

[0034] like Figure 5As shown, the level detection device also includes a power supply 14 and a switch 15. The switch 15 is arranged near the power supply 14. The switch 15 is used to control the connection and disconnection of the power supply 14 and the first circuit 111, and the connection and disconnection of the power supply 14 and the second circuit 131. The light source chamber 11 is provided with a first circuit 111, and the first light source 112 is electrically connected to the first circuit 111. The indication chamber 13 is provided with a second circuit 131. The indication chamber 13 is provided with a photoresistor 132 electrically connected to the second light source 133. The photoresistor 132 and the second light source 133 are arranged in series. The second light source 133 and the photoresistor 132 are electrically connected to the second circuit 131 respectively. The first circuit 111 and the second circuit 131 are electrically connected to the power supply 14 respectively. The first circuit 111 and the second circuit 131 are arranged in parallel.

[0036] like Figures 2 to 4 As shown, the barrier structure 121 includes a first end 1211, a rolling portion 1212 and a second end 1213 that are fixedly connected. The first end 1211 is arranged corresponding to the first light-transmitting area 101, and the second end 1213 is arranged corresponding to the second light-transmitting area 102. The rolling portion 1212 is a cylinder. A bearing surface is provided in the barrier chamber 12. The barrier structure 121 is arranged on the bearing surface. The bearing surface is an arc-shaped surface, and the rolling portion 1212 can roll on the bearing surface.

[0037] like Figure 3 and Figure 4As shown, the bearing surface is a first bearing surface 1214, which is arranged at the bottom of the baffle chamber 12, and the arc surface of the first bearing surface 1214 is recessed in the X direction, and the density of the baffle structure 121 is greater than the density of the liquid or the density of the gas in the baffle chamber 12; for example, the material of the baffle structure 121 is, for example, stainless steel or iron, etc., which can make the baffle structure 121 sink to the bottom of the baffle chamber 12 and contact with the first bearing surface 1214. When the horizontal detection device is in a horizontal state, the baffle structure 121 is located in the middle of the first bearing surface 1214, and the two ends of the baffle structure 121 respectively cover the first light-transmitting area 101 and the second light-transmitting area 102, and the light of the first light source 112 of the light source chamber 11 cannot be projected to the indication chamber 13, the resistance value of the photoresistor 132 in the indication chamber 13 is large, the loop of the second circuit 131 is disconnected, and the second light source 133 is in an off state.

[0038] like Figures 2 to 4 As shown, the first end 1211 is cylindrical or rectangular, and the second end 1213 is cylindrical or rectangular, so the shapes of the first light-transmitting area 101 and the second light-transmitting area 102 are respectively matched with the shapes of the first end 1211 and the second end 1213. For example, when the first end 1211 and the second end 1213 are cylindrical, the inner diameter of the first light-transmitting area 101 is greater than or equal to the inner diameter of the first end 1211, and the inner diameter of the second end 1213 is greater than or equal to the inner diameter of the second light-transmitting area 102, so that the barrier structure 121 can cover the first light-transmitting area 101 and the second light-transmitting area 102; when the first end 1211 and the second end 1213 are rectangular, the width of the first light-transmitting area 101 is greater than or equal to the width of the first end 1211, and the width of the second end 1213 is greater than or equal to the width of the second light-transmitting area 102, so that the barrier structure 121 can cover the first light-transmitting area 101 and the second light-transmitting area 102.

[0039] Second embodiment

[0040] like Figures 6 to 8 As shown, the level detection device of this embodiment is substantially the same in structure as the level detection device of the first embodiment, except that the structure of the bearing surface is different.

[0041] Specifically, the first light-transmitting area 101 and the second light-transmitting area 102 are arranged at the top of the baffle chamber 12, and the bearing surface is the second bearing surface 1215. The second bearing surface 1215 is arranged at the top of the baffle chamber 12, and the second bearing surface 1215 is recessed in the Y direction. The density of the baffle structure 121 is less than the density of the liquid or the density of the gas in the baffle chamber 12, so that the baffle structure 121 floats to the top of the baffle chamber 12 and contacts with the second bearing surface 1215. When the level detection device is in a horizontal state, the baffle structure 121 is located in the middle of the second bearing surface 1215, and the two ends of the baffle structure 121 cover the first light-transmitting area 101 and the second light-transmitting area 102 respectively. The light from the first light source 112 of the light source chamber 11 cannot be projected into the indication chamber 13, the resistance value of the photoresistor 132 in the indication chamber 13 is large, the loop of the second circuit 131 is disconnected, and the second light source 133 is in an off state; when the horizontal detection device is in an inclined state, the blocking structure 121 cannot completely cover the first light-transmitting area 101 and the second light-transmitting area 102, and the light in the light source chamber 11 is incident into the indication chamber 13 through the first light-transmitting area 101, the blocking chamber 12, and the second light-transmitting area 102, and the resistance value of the photoresistor 132 in the indication chamber 13 decreases rapidly with the increase of light intensity, and at this time the second circuit 131 forms a loop, and the second light source 133 is lit.

[0042] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the attached claims.
