Description

Technical Field

[0001] This utility model relates to the field of warning device technology, specifically a safety warning device for water conservancy project management. Background Technology

[0002] Water conservancy project management controls the conditions of the construction site through on-site management, and deepens and manages construction safety regulations based on detailed construction technical regulations and actual construction characteristics. When managing water conservancy projects, it is necessary to warn about equipment to prevent outsiders from accidentally entering the construction area.

[0003] Patent document CN217499996U discloses a safety warning device for water conservancy project construction management, including a base, a support column fixedly connected to the top of the base, a bearing fixedly connected to the top of the support column, and a telescopic rod fixedly connected to the surface of the bearing. This utility model has the following advantages and effects: By setting up a base, support column, bearing, telescopic rod, moving ring, connecting rod, and fixing bolts, when installing the safety warning device, first adjust the telescopic rod, rotate the telescopic rod, and rotate the bearing connected to the bottom of the telescopic rod, allowing the telescopic rod to rotate, thus enabling the safety warning device to change its orientation. Then, adjust the height of the telescopic rod; raising the telescopic rod increases the height of the entire device. Finally, tighten the fixing bolts to fix the moving ring at a suitable height. The moving ring is connected to a warning sign, and the position of the warning sign can be adjusted by adjusting the height of the moving ring.

[0004] The above solution achieves its warning function by setting up warning signs. However, in actual use, it can only provide a warning effect to the front and back of the warning signs, and cannot warn the sides of the warning signs, resulting in blind spots. In addition, the sliding wheels in the above solution are fixedly installed under the base, which means that the weight of the warning device is entirely on the sliding wheels. This makes it difficult to stably mount the device on the ground, and the device is prone to displacement due to the smoothness of the sliding wheels, resulting in poor stability.

[0015] With the second threaded cylinder and the base plate, the warning device can be stably erected on the ground by the base plate pressing against the ground.

[0016] In a preferred embodiment, limit sliders are provided on both sides of the second threaded cylinder, and limit grooves for the limit sliders to slide are provided on both sides of the inner wall of the transmission groove.

[0017] Guided by the limiting slider, the second threaded cylinder can drive the base plate to move up and down in a directional manner through the rotation of the lead screw.

[0018] In a preferred embodiment, the lower surface of the base plate is provided with reinforcing nails, and the number of reinforcing nails is several, arranged in a circumferential array on the lower surface of the base plate.
