Description

Technical Field

[0001] This invention relates to the field of water control technology devices, and in particular to an automatic lifting dam. Background Technology

[0002] Flood control sandbags, also known as fire-fighting sandbags, waterproof sandbags, fire-fighting sandbags, flood-resistant sandbags, and flood prevention sandbags, are essential for low-lying areas, basement entrances, garages, etc., during the rainy season. They enable the quickest completion of temporary waterproofing works, making it easy to move sandbags. They are also essential for emergency disasters, typhoons, floods, drainage projects, garage flood barriers, prevention of landslides, and other emergency temporary works and flood prevention.

[0003] As the climate worsens and the rainy season arrives, the frequency of rainfall increases, leading to more instances of backflow. In many places, it is necessary to build dams to block the flow of water. However, currently, most artificial dams are constructed by filling sandbags with gravel, requiring long-term personnel to maintain them. As the water level rises, more sandbags are added to increase the height of the dam. After the rainy season, workers need to be hired to clean it, which is time-consuming and labor-intensive.

[0004] Based on this, the present invention designs an automatic lifting dam to solve the above problems. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide an automatic lifting dam, which aims to solve the problems of current manual dam construction, which often uses burlap sacks filled with sand and gravel, requires long-term personnel on duty, and involves constantly adding burlap sacks and increasing the height of the dam as the water level rises; after the rainy season, it is also necessary to hire workers to clean it, which is time-consuming and labor-intensive.

[0007] (II) Technical Solution

[0008] Specifically: An automatic lifting dam includes a dam body and a base. A support mechanism is installed between the dam body and the base. A control unit is installed inside the base. The control unit consists of sensors and a controller. The sensor array is distributed between the dam body and the base. The sensors are used to sense changes in water level. The controller is interconnected with the support mechanism and is used to control the extension and retraction of the support mechanism to control the height of the dam body. Multiple retractable hidden wheels are installed at the bottom of the base. The hidden wheels are used to improve the overall mobility after activation.

[0009] Sensors detect changes in water level, and the controller adjusts the extension and retraction of the support mechanism to control the height of the dam. This allows the support mechanism to raise the dam and block the water flow. When the sensor detects a decrease in water level, the controller lowers the dam to its initial position. Using this dam eliminates the need for extensive personnel and time-consuming tasks like filling burlap sacks to increase its height; the dam automatically raises as the water level rises, saving labor and time and increasing efficiency. The dam's retractable wheels enhance mobility, allowing for easy movement to any location. After the rainy season, no cleaning is required, saving time and effort.

[0010] The technical solution of this application will be further described below:

[0011] In one embodiment, the support mechanism is an X-shaped support mechanism; wherein, the X-shaped support mechanism includes two support rods, namely support rod one and support rod two, which are distributed in an X shape, and the middle parts of support rod one and support rod two are rotatably connected by a rotating column; the two ends of support rod one and support rod two are slidably connected to the dam body and the base, respectively.

[0012] In a further embodiment, hydraulic rods are installed on the sides of the first and second support rods.

[0013] In one embodiment, the base contains a battery compartment and multiple sets of counterweights.

[0014] In a further embodiment, the multiple sets of counterweights consist of counterweight one, counterweight two, counterweight three, counterweight four, and counterweight five.

[0015] In one embodiment, the base has multiple through-holes, and the base has a trapezoidal cross-section, which is stable and reliable. Rubber is provided around the base, and the rubber extends outward to block water more directly. The outer shell of the water-blocking dam is an ABS engineering plastic shell.

[0016] In one embodiment, a spring is fixed to the concealed wheel, and the spring is mounted on the base at the end away from the concealed wheel; a limiting mechanism is mounted on the concealed wheel to limit the state of the concealed wheel.

[0017] In a further embodiment, the limiting mechanism includes an elastic protrusion and a limiter hole. The elastic protrusion is elastically and telescopically connected to the hidden wheel, and there are two limiter holes, which are equally spaced on the base.

[0018] In one embodiment, a plurality of latches are installed on the side wall of the base, the latches being used for assembling and connecting the multiple bases together.

[0019] In a further embodiment, the latch includes a latch storage box, a rotating column is rotatably connected to the latch storage box, and a latch hanging ring is rotatably connected to the rotating column. The latch hanging ring is used to detachably fasten to the latch limiting hook.

[0020] When the locking ring is engaged with the locking limit hook, multiple bases can be connected in series; when the locking ring is released from the locking limit hook, it can be used independently.

[0021] (III) Beneficial Effects

[0022] Compared with existing technologies, the automatic lifting dam of this invention can achieve the following:

[0023] 1. The sensor detects changes in water level, and the controller controls the extension and retraction of the support mechanism to control the height of the dam. This allows the support mechanism to raise the dam and block the water flow. When the sensor detects a decrease in water level, the controller controls the support mechanism to lower the dam to its initial position. Using this dam, there is no need for a large number of personnel on duty, nor is it necessary to spend time and effort filling burlap sacks to increase the height of the sacks. The dam will automatically raise the water barrier according to the increase in water level.

[0024] 2. After retracting the concealed wheels, use the dam to block the water flow; after blocking the water flow, extend the concealed wheels to improve overall mobility; it is easy to move to any place; after the rainy season, there is no need to hire workers to clean it, avoiding time and effort.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The specific implementation of the invention will be described in detail below with reference to specific embodiments.

[0040] In embodiments of the present invention, such as Figure 1 , 2 As shown in Figure 5: An automatic lifting dam includes a dam body 110 and a base 130. A support mechanism 131 is installed between the dam body 110 and the base 130. A control unit 132 is installed inside the base 130. The control unit 132 consists of sensors and a controller. The sensor array is distributed between the dam body 110 and the base 130. The sensors are used to sense changes in water level. The controller is interconnected with the support mechanism 131 and is used to control the extension and retraction of the support mechanism 131 to control the height of the dam body 110. A waterproof cloth 160 is connected to the outside of the dam body 110.

[0041] It should be noted that the sensor and controller are existing technologies, and their detailed structures can be found in existing literature and journals. They can also be purchased directly from the market or assembled from components purchased from the market. They are not protected by this invention and will not be described in detail here, nor are they shown in the accompanying drawings.

[0042] Based on the above description, it can be concluded that: the sensor detects changes in water level, and the controller controls the extension and retraction adjustment of the support mechanism 131 to control the height of the dam body 110, thereby raising the dam body 110 to block the water flow; after the sensor detects a decrease in water level, the controller controls the support mechanism 131 to lower the dam body 110 along with the water level until it reaches its initial position; using this dam eliminates the need for a large number of personnel on duty, and eliminates the need for time-consuming and laborious filling of burlap sacks to increase the height of the sacks, as the dam will automatically raise the water barrier according to the increase in water level; saving labor and time, and relatively improving work efficiency;

[0043] The base 130 has multiple retractable hidden wheels 140 installed at its bottom. The hidden wheels 140 are used to improve the overall mobility after being activated.

[0044] Based on the above description, it can be concluded that: after the concealed wheels 140 are stowed away, the water-blocking dam body 110 is used to block the water flow; after the water flow is blocked, the concealed wheels 140 are extended outward to improve the overall mobility; it is easy to move to any place; after the rainy season, there is no need to hire workers to clean it, avoiding time and effort; it saves labor and time, and relatively improves work efficiency.

[0045] In embodiments of the present invention, such as Figure 3 As shown: The support mechanism 131 is an X-shaped support mechanism;

[0046] The X-shaped support mechanism includes two X-shaped support rods 1311 and 1312, which are rotatably connected at the middle by a rotating column. The two ends of the support rods 1311 and 1312 are slidably connected to the dam body 110 and the base 130, respectively.

[0047] like Figure 3 As shown: Hydraulic rods 1313 are installed on the sides of the first support rod 1311 and the second support rod 1312.

[0048] Based on the above description, it can be concluded that: the sensor senses the change in water level, the controller controls the hydraulic rod 1313 to extend and retract, and completes the extension and retraction adjustment of the support mechanism 131, thereby controlling the height of the dam body 110, and realizing the support mechanism 131 controlling the raising of the dam body 110 to block the water flow.

[0049] In the embodiments of the present invention, such as Figure 2 As shown: The base 130 contains a battery compartment 135 and multiple sets of counterweights.

[0050] like Figure 2As shown: the multiple sets of counterweights consist of weight-increasing item 133, weight-increasing item 2134, weight-increasing item 3136, weight-increasing item 4137 and weight-increasing item 5138.

[0051] In embodiments of the present invention, such as Figure 1 and Figure 2 As shown: The base 130 has multiple through holes 120, and the cross-section of the base 130 is trapezoidal, which is stable and reliable; the base 130 is surrounded by rubber, which extends outward to block water more directly; the outer shell of the water-blocking dam body 110 is an ABS engineering plastic shell.

[0052] In embodiments of the present invention, such as Figure 4 and Figure 5 As shown: A spring 141 is fixed on the concealed wheel 140, and the end of the spring 141 away from the concealed wheel 140 is mounted on the base 130;

[0053] A limiting mechanism is installed on the concealed wheel 140, which is used to limit the state of the concealed wheel 140.

[0054] like Figure 4 and Figure 5 As shown: The limiting mechanism includes an elastic protrusion 142 and a limiter hole 143. The elastic protrusion 142 is elastically telescopically connected to the hidden wheel 140. There are two limiter holes 143, which are equally spaced on the base 130.

[0055] Based on the above description, it can be concluded that: with the elastic protrusion 142 inserted and limited in the upper limiter hole 143 of the two limiter holes 143, the concealed wheel 140 is retracted. At this time, the water-blocking dam body 110 is used to block the water flow; after the water flow is blocked, the concealed wheel 140 extends outward, and the elastic protrusion 142 inserted and limited in the lower limiter hole 143 of the two limiter holes 143, improving the overall mobility; it is easy to move to any place; after the rainy season, there is no need to hire workers for cleaning, avoiding time and effort; it saves labor and time, and relatively improves work efficiency.

[0056] In the embodiments of the present invention, such as Figure 6 As shown: Multiple latches 150 are installed on the side wall of the base 130, and the latches 150 are used for assembly and connection between the multiple bases 130.

[0057] like Figure 6 As shown: The latch 150 includes a latch storage box 151, a rotating column 152 is rotatably connected to the latch storage box 151, and a latch hanging ring 153 is rotatably connected to the rotating column 152. The latch hanging ring 153 is used to detachably fasten to the latch limiting hook 154.

[0058] Based on the above description, it can be concluded that: when the locking ring 153 is engaged with the locking limit hook 154, multiple bases 130 can be connected in series; when the locking ring 153 is unengaged from the locking limit hook 154, it can be used independently.

[0059] Currently, many artificial dams are constructed using burlap sacks filled with sand and gravel, requiring long-term personnel presence. As water levels rise, more burlap sacks are added, increasing the dam's height. After the rainy season, cleaning is necessary, which is time-consuming and labor-intensive. This invention, an automatic lifting dam, addresses these problems:

[0060] The sensor detects changes in water level, and the controller controls the extension and retraction of the support mechanism 131 to control the height of the dam body 110, thus raising the dam body 110 to block the water flow. When the sensor detects a decrease in water level, the controller controls the support mechanism 131 to lower the dam body 110 to its initial position. Using this dam eliminates the need for extensive personnel on duty and the time-consuming and laborious process of filling burlap sacks to increase the sack height, as the dam automatically raises to block the water as the water level rises. After the hidden wheels 140 are retracted, the dam body 110 blocks the water flow. Once the water flow is blocked, the hidden wheels 140 are extended to improve overall mobility, making it easy to move to any location. After the rainy season, there is no need to hire workers for cleaning, avoiding time and labor costs.

[0061] In the description of this invention, unless otherwise stated, "a plurality of" means two or more.
