Description

Technical Field

[0001] The present application relates to the technical field of water conservancy construction, and in particular to a small and medium-sized precast intercepting device. Background Art

[0002] A diversion device is a device that can block the flow of water. It usually comes in many different types, such as precast, manual single-piece, and motor-powered. It is widely used in drainage channels and drains.

[0003] Industries such as semiconductors, chemical plants, and pharmaceuticals often use and store large amounts of chemical reagents. When chemicals are discharged, they are separated, diverted, collected, and processed before being discharged. However, due to improper human management or aging and leakage of storage packaging materials (storage tanks), they often flow into abnormal drainage channels, causing pollution and safety issues. At this time, it is necessary to use interception devices to isolate pollutants and reduce the risk of harmful substances flowing into normal water sources and causing pollution.

[0004] In the related technologies, the intercepting devices of drainage ditches in various industrial parks require manpower or power to operate water-blocking valves, which lack the timeliness to respond to sudden abnormalities. Utility Model Content

[0005] In order to solve the problem that the interception device in the related art lacks the timeliness to deal with sudden abnormal situations and easily causes the flatness of the road surface after installation, the present application provides a small and medium-sized precast interception device.

[0006] The present application provides a small and medium-sized precast interception device adopts the following technical solution:

[0007] A small and medium-sized precast intercepting device comprises a shell and a plurality of baffles. A groove is provided at the bottom of the shell. A control component for controlling the closing of the baffles is arranged at the bottom of the groove.

[0008] By adopting the above technical solution: this specially designed shell can better adapt to the structure of the drainage channel under different circumstances. At the same time, the control component installed in the groove can timely control the closing of the baffle, so that the intercepting device can perform immediate blocking and collection, which can greatly reduce the impact on surrounding facilities and the ecological environment.

[0009] Preferably, the control component includes a detector and a signal transmitter disposed on the detector.

[0010] By adopting the above technical solution: the detector detects the flowing water flow. If harmful substances are detected, a signal is sent through the signal transmitter to close the baffle in time, thereby achieving the purpose of blocking the water flow.

[0011] Preferably, a movable baffle for supporting a plurality of baffles is also provided on the inner wall of the shell.

[0012] By adopting the above technical solution, the movable baffle is provided so as to support the baffle plate and also to control the switch of the baffle plate to be closed.

[0013] Preferably, the movable baffle includes an upper baffle and a left baffle and a right baffle rotatably disposed on the upper baffle along a vertical direction.

[0014] By adopting the above technical solution, the left baffle and the right baffle are rotated by a certain angle in the vertical direction, so that a plurality of baffles supported thereon can be lowered to realize the switch closing of the baffle.

[0015] Preferably, the surfaces of the left baffle and the right baffle are both provided with an anti-rust coating.

[0016] By adopting the above technical solution: the setting of the anti-rust layer makes the weight of the left baffle and the right baffle greater than the weight of the upper baffle when they are rotated to the vertical direction, making it difficult for them to float up. At the same time, it is also beneficial to reduce the risk of rust on the baffle and extend the effective service life.

[0017] Preferably, one end of the signal transmitter away from the detector is connected to a movable baffle.

[0018] By adopting the above technical solution: the detector detects the set related substances and transmits the information to the signal transmitter, and the signal transmitter immediately sends a closing signal to the movable baffle, so that it can lower the baffle in time.

[0019] Preferably, the two side surfaces of the support platform parallel to the baffles are provided with bosses corresponding to a plurality of the baffles in a stepped manner from top to bottom.

[0020] By adopting the above technical solution: when the movable baffle rotates in the vertical direction, a plurality of baffles fall onto the boss by their own gravity and are sealed layer by layer, which is conducive to blocking the flow of water.

[0021] Preferably, a Teflon acid- and alkali-resistant layer is also provided on the shell.

[0022] By adopting the above technical solution: the Teflon acid and alkali resistant layer enables the intercepting device to effectively reduce the risk of being corroded by chemical substances, which is beneficial to prolonging the adaptability life.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. This application designs a special precast shell with grooves, which can be well adapted to the structure of drainage channels in different situations, reducing the impact on the flatness of the road surface. At the same time, the detector installed in the groove can detect the water flow passing through, and cooperate with the baffle to enable the interception device to block and collect water immediately, which can greatly reduce the impact on surrounding facilities and the ecological environment;

[0025] 2. The present application connects the movable baffle with the detector through a signal transmitter, so that the baffle can be linked in time to automatically fall down, thereby achieving the purpose of blocking the flow of water;

[0026] 3. The present application provides the intercepting device with certain anti-corrosion and anti-rust properties by respectively arranging an anti-rust layer and a Teflon acid- and alkali-resistant layer on the movable baffle and the shell, thereby reducing the risk of corrosion by chemical substances and rust by water and oxygen, and is conducive to extending the service life of the device.

[0031] The following is combined with Figure 1-3 This application is described in further detail. Example

[0032] The present application embodiment discloses a small and medium-sized precast current-carrying device, referring to Figure 1 and Figure 2 , including a housing 1, a groove 3 is provided at the bottom of the housing 1, a support platform 31 is installed in the groove 3, a detector 32 is installed between the groove 3 and the support platform 31, and a movable baffle 12 is symmetrically installed on two surfaces of the inner wall of the housing 1 perpendicular to the groove 3, referring to Figure 3, wherein the baffle is composed of an upper baffle 111, a left baffle 112, and a right baffle 113, and the left baffle 112 and the right baffle 113 can rotate around the upper baffle 111 in a vertical direction;

[0033] Four baffles 2 are installed on the left baffle 112 and the right baffle 113 respectively. The installation height of the baffle is flush with the top of the support platform 31, so that the support platform 31 can also play a certain supporting role for the baffle 2. Bosses 311 corresponding to the baffles 2 are arranged in a stepped manner from top to bottom on the two side surfaces of the support platform 31 parallel to the baffle 2. When the left baffle 112 and the right baffle 113 are turned to the vertical position, due to the self-gravity of the baffles, they will slide down from the baffle to the boss 311 from top to bottom and adapt to it, thereby blocking the water flow and achieving a close fit and anti-seepage.

[0034] In order to enable the interception device to take timely measures to block the water flow when the detector 32 detects harmful chemicals, refer to Figure 1 and Figure 2 A signal transmitter 4 is also installed between the movable baffle 12 and the detector 32, so that the baffle 2 can be linked in time to automatically fall down, thereby achieving the purpose of blocking the flow of water.

[0035] To reduce the risk of interception devices being corroded by chemicals and rusted by water and oxygen and to extend the service life of the devices as much as possible, refer to Figure 1 and Figure 2 An anti-rust layer 114 and a Teflon acid- and alkali-resistant layer 11 are respectively provided on the left baffle 112, the right baffle 113 of the movable baffle 12 and the shell 1, so that the intercepting device can effectively reduce the possibility of being corroded. At the same time, when the left baffle 112 and the right baffle 113 are rotated to the vertical direction, their weight is greater than the weight of the upper baffle 111, so that it is not easy to float.

[0036] The working process and implementation principle of Example 1 are as follows: before the device is started, the left baffle 112 and the right baffle 113 are placed in a horizontal direction to support the weight of the baffle 2. When the detector 32 installed between the bottom of the support platform 31 and the groove 3 detects the flow of the set relevant harmful chemical substances, it transmits the relevant information to the signal transmitter 4. At this time, the signal transmitter 4 immediately sends a control signal to the baffle, so that the left baffle 112 and the right baffle 113 rotate from top to bottom in the vertical direction, and the baffle 2 is affected by its own weight and slides to the corresponding boss 311 on the support platform 31, so that the water flow on both sides of the groove 3 is blocked. The two-way gate formed by the baffle 2 can achieve a tightly fitting state by the water flow (volume) pressure. In addition, thanks to the setting of the anti-rust coating 114 and the Teflon acid and alkali resistant layer 11, the intercepting device can effectively reduce the risk of erosion and extend its service life.

[0037] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
