Fig. 1 is an elevation view of a lateral slope detection device. Referring to fig. 1, the present utility model provides a lateral slope detection apparatus, which includes a horizontal member 100 and a vertical member 200, wherein the horizontal member 100 includes a horizontal part 101 having a through length for maintaining parallelism with a slope direction of a road surface to be detected. The vertical member 200 is vertically and fixedly arranged on the horizontal member 101, and is used for displaying the height difference of different positions of the horizontal member 101, and comprises at least two liquid level displays 201 which are arranged in parallel; while the horizontal member 101 communicates with a plurality of level indicators 201 such that there is an association between the level indicators 201.

When the lateral slope detection device in this embodiment is placed on the road surface to be detected, the height difference between the liquid level displays 201 is read, the linear distance between the liquid level displays 201 on the horizontal member 101 can be calculated, the included angle between the horizontal member 101 and the environmental horizontal plane at this time can be calculated, and the lateral slope of the road surface to be detected can be calculated by using the triangular relationship.

The transverse slope detection device provided by the embodiment is placed on the road surface to be detected, the gradient of the road surface to be detected is mapped by the horizontal member 100, and the transverse slope of the road surface to be detected can be calculated by reading the liquid level height differences displayed by the plurality of communicated liquid level displays 201 arranged on the horizontal piece 101 and the length of the horizontal piece 101, so that the operation steps are simplified, and the device has the advantages of integrity and portability, convenience in transverse slope measurement and friendly operability for common personnel.

In some examples, as shown in fig. 1, the liquid level display 201 has two and is provided separately at both ends of the horizontal member 101.

The level difference between the two ends of the horizontal member 101 can be reflected by displaying the level difference by using the level displays 201 which are respectively arranged at the two ends of the horizontal member 101 and are communicated with each other, so that a foundation is provided for calculating the transverse slope.

As shown in fig. 1, the liquid level display 201 may include a vertical transparent tube 201a, and scale marks 201a-1 are provided on a tube wall of the vertical transparent tube 201 a; and a liquid 201b provided in the vertically transparent tube 201 a. Specifically, in this embodiment, the vertical transparent tube 201a is a square transparent glass tube, which has the characteristics of easily available materials and strong plasticity.

The transparent tube and the scale marks 201a-1 are utilized to clearly read the liquid level, while the liquid 201b inside has the characteristic of automatic level, and the liquid level surface at any height can be mapped, so that the liquid level displays 201 on two sides can display the height difference, and the staff can conveniently read the data.

As shown in fig. 1, the horizontal member 101 may be in communication with the bottoms of two level indicators 201, with the liquid 201b flowing through the horizontal member 101 and between the two level indicators 201.

The arrangement of the horizontal piece 101 not only meets the gradient simulation of the road surface to be tested, but also can provide a circulating channel for the liquid 201b in the two liquid level displays 201, and provides a foundation for the liquid level displays 201 on two sides to present different liquid level heights.

Specifically, the horizontal member 101 may include a transverse channel 101a, and preferably, the transverse channel 101a is a square transparent glass tube.

Meanwhile, as shown in fig. 2, the vertical transparent tube 201a and the lateral duct 101a have the same cross-sectional shape and area.

Because the cross sections of the vertical transparent pipe 201a and the transverse pipeline 101a are the same, the liquid 201b can be uniformly distributed in the whole communicating vessel in the structure similar to the communicating vessel, so that the height difference of the liquid level displays 201 on two sides can be accurately reflected, and the accuracy of the transverse slope calculation result is ensured.

As shown in fig. 2 and 3, the horizontal member 100 may further include supporting feet 102, and the supporting feet 102 are provided with three, which are connected to both ends and the middle of the horizontal member 101, to provide stable support for the horizontal member 101.

The plurality of support feet 102 allow the horizontal member 101 to be separated from the ground, thereby providing protection for the lateral channel 101a within the horizontal member 101. And the support feet 102 can also increase the overall out-of-plane stability of the device, enabling adaptation to complex survey environments.

As shown in fig. 1 to 3, the lower ends of the plurality of support legs 102 are coplanar and lie in a plane parallel to the direction of the horizontal member 101.

The lower ends of the supporting feet 102 are arranged in a coplanar manner, so that the parallelism between the horizontal piece 101 and the road surface to be tested can be ensured, and the gradient of the road surface to be tested can be accurately reflected.

As shown in fig. 1, the apparatus in this embodiment further includes a support member 300, and the support member 300 connects the horizontal member 100 and the vertical member 200 and forms a frame with the horizontal member 100 and the vertical member 200.

The structure of the apparatus is framed by the support members 300, so that the position between the vertical members 200 of the horizontal member 100 can be effectively maintained to be vertical, thereby ensuring the accuracy of the level difference display. At the same time, the formed frame also improves the integrity of the device, making the device easy to handle and place.

Specifically, as shown in fig. 1, the supporting member 300 includes a cross beam 301 and a vertical beam 302, and the cross beam 301 is parallel to the horizontal member 101 and connected to the top of the liquid level display; the vertical beam 302 is parallel to the liquid level display 201, and both ends are connected to the middle portions of the horizontal member 101 and the cross beam 301, respectively.

The cross member 301 can hold the liquid level display 201 on both sides at a fixed distance and is supported as an upper portion of the frame to receive a certain axial force. While the middle vertical beam 302 maintains the distance between the horizontal member 101 and the cross beam 301, and the cross beam 301 is greatly deformed after being bent. It is thus possible to keep the level indicator 201 and the horizontal member 101 vertical.

As shown in fig. 4, the working principle of the lateral slope detection device is shown, the lateral slope detection device is placed on the ground with a lateral slope, the rectangular transparent glass tube is filled with liquid 201b, finally the liquid level of the glass tubes at two sides can be kept level with the ground, and the heights of the liquid level displays at two sides are respectively AC and FE. The geometric relationship of the graph can be used to obtain the length fe=bc of the liquid level display 201 at two ends of the liquid level line, and the relationship of bf=ce exists between the length BF of the horizontal member 101 and the length CE of the liquid level line projected on the horizontal member 101. The length CE of the horizontal member 101 may be set to a fixed value during processing and manufacturing, and the height difference ab=ac-FE of the liquid surface display may be calculated, so that the two right-angle sides AB and BF are both known, the angle a may be calculated according to a trigonometric function, the angle a and the angle a' may be equal, the ED and CD may be calculated according to a trigonometric function, and finally the slope value of the ground slope angle a may be obtained by calculating the slope=ed/CD of the ground.
