Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sealed gates for fully underground regulating reservoirs, and in particular to a sealing structure for a quick-opening gate. Background Technology
[0002] Wastewater storage tanks, also known as reservoirs, water storage ponds, or stormwater and wastewater separation and storage facilities, are facilities used to treat urban wastewater. Their main function is to temporarily store wastewater and smoothly discharge it when the urban drainage system is overloaded or exceeds its design capacity, thereby avoiding direct discharge of wastewater and environmental pollution. Simultaneously, they can effectively alleviate pressure on urban drainage systems and reduce water pollution and urban flooding caused by extreme conditions such as heavy rain. Furthermore, they can also serve as a water source for irrigation and landscaping, enabling water recycling.
[0003] Fully underground wastewater storage tanks place the entire structure underground to minimize impact on surface space and improve the overall aesthetics and land utilization of the city. The gates in a fully underground wastewater storage tank are a key component, playing a crucial role in controlling water levels, regulating flow, and achieving effective wastewater treatment and discharge. Existing gate sealing structures typically employ a side-clamping structure to ensure tight sealing at the gate's sealing points. However, fully underground storage tank gates also require sealing at the top. The side-clamping structure provides relatively weak sealing force at the top, creating a risk of leakage at the gate's top seal. Utility Model Content
[0004] This application provides a quick-opening gate sealing structure to improve the overall sealing effect of the gate.
[0005] This application provides a quick-opening gate sealing structure, including:
[0006] Side sealing strips are disposed on both sides of the gate and at positions corresponding to the gate frame, and the side sealing strips are used to form a contact seal between them;
[0007] A side-pressing mechanism is disposed between the two sides of the gate and the gate frame;
[0008] A top sealing strip is disposed on the top of the gate and the top of the gate frame, and the top sealing strip is used to form a contact seal between the top sealing strips;
[0009] A top pressing mechanism is disposed between the top of the gate and the top of the gate frame;
[0010] A bottom sealing strip is disposed at the bottom of the gate, and the bottom sealing strip is used to form a contact seal with the bottom of the gate frame.
[0011] The beneficial effects of the above embodiments are as follows: when the gate is closed, the top pressing mechanism applies pressure to the top sealing strip to improve the sealing effect between the top of the gate and the gate frame; the side pressing mechanism applies pressure to the side sealing strip to improve the sealing effect between the side of the gate and the gate frame; and the bottom sealing strip applies pressure to the bottom of the gate to improve the sealing effect between the bottom of the gate and the gate frame, thereby forming a good sealing structure around the gate and the gate frame.
[0012] Based on the above embodiments, the embodiments of this application can be further improved as follows:
[0013] In one embodiment of this application, both the side sealing strip and the top sealing strip are made of copper. The beneficial effects of this step are: copper has excellent sealing performance, which can improve the sealing effect between the gate and the gate frame; copper has a lower coefficient of friction than rubber, thus greatly increasing the opening and closing speed of the gate, giving the gate the characteristics of quick opening and quick closing.
[0014] In one embodiment of this application: the side sealing strip and the top sealing strip are inserted into the corresponding grooves opened in the gate or the gate frame.
[0015] In one embodiment of this application, the groove is a dovetail groove. The beneficial effect of this step is that the combination of the copper strip and the dovetail groove structure improves the stability and sealing performance of the connected structure.
[0016] In one embodiment of this application: the roughness of the friction contact surface of the side sealing strip and the friction contact surface of the top sealing strip is less than or equal to 0.2 μm, and the flatness is less than or equal to 3 μm. The beneficial effect of this step is that by limiting the roughness and flatness of the copper strip contact surface, the copper strip achieves good sealing and guiding effects after contact.
[0017] In one embodiment of this application: the side clamping mechanism includes: a first side wedge and a second side wedge. The first side wedge is installed on the gate, and the second side wedge is installed on the gate frame. In the top-to-bottom direction, the contact surface between the first side wedge and the second side wedge is an inclined surface oriented towards the gate. The beneficial effect of this step is that the wedge structure allows the side sealing strip to form a locking structure during the gate closing process.
[0018] In one embodiment of this application: the top clamping mechanism includes: a first top wedge and a second top wedge. The first top wedge is installed on the gate, and the second top wedge is installed on the gate frame. In the top-to-bottom direction, the contact surface between the first top wedge and the second top wedge is an inclined surface facing away from the gate. The beneficial effect of this step is that the wedge structure allows the top sealing strip to form a locking structure during the gate closing process.
[0019] In one embodiment of this application, the bottom sealing strip is made of rubber. The beneficial effect of this step is that, since the bottom sealing strip and the bottom of the gate frame are mainly in compression contact during the closing or opening of the gate, with virtually no friction, the elastic deformation of the rubber strip allows the bottom of the gate and the bottom of the gate frame to form a good sealing structure.

For example, a connection can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0026] In the description of this application, it should be understood that the directional terms or positional relationships described are based on the orientation or positional relationships shown in the accompanying drawings, or based on the orientation or positional relationships in actual use, and are only for the purpose of facilitating the description of the contents of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0027] like Figure 1 , 2As shown in Figure 3, a quick-opening gate sealing structure includes: a side sealing strip 1, a side pressing mechanism 2, a top sealing strip 3, a top pressing mechanism 4, and a bottom sealing strip 5. The side sealing strips 1 are disposed on both sides of the gate 6 and corresponding to the gate frame 7, and are used to form a contact seal between the side sealing strips 1. The side pressing mechanism 2 is disposed between both sides of the gate 6 and the gate frame 7. The top sealing strip 3 is disposed on the top of the gate 6 and the top of the gate frame 7, and is used to form a contact seal between the top sealing strips 3. The top pressing mechanism 4 is disposed between the top of the gate 6 and the top of the gate frame 7. The bottom sealing strip 5 is disposed at the bottom of the gate 6, and is used to form a contact seal with the bottom of the gate frame 7.
[0028] In some embodiments of this application, both the side sealing strip 1 and the top sealing strip 3 are made of copper. Specifically, both the side sealing strip 1 and the top sealing strip 3 are copper strips. The reason for using copper strips is that: (1) Copper sealing strips have excellent sealing performance. Copper has stable chemical properties and can resist oxidation and corrosion well. Therefore, copper sealing strips can maintain good sealing performance during long-term use and prevent sewage leakage; (2) Copper has good plasticity. The plasticity and machinability of copper make it easy to process into various shapes and sizes to meet the different requirements of the sealing surface of the gate 6 and ensure the tightness and reliability of the seal; (3) Copper has a long service life. Due to the chemical stability and corrosion resistance of copper, the service life of copper sealing strips is relatively long, reducing the frequency of replacement and maintenance and reducing the cost of use; (4) Copper has good guiding performance. Copper has a low coefficient of friction relative to rubber, so it can greatly improve the opening and closing speed of the gate 6, so that the gate 6 has the characteristics of fast opening and fast closing.
[0029] In some embodiments of this application, such as Figure 2 , 3 As shown, the side sealing strip 1 and the top sealing strip 3 are inserted into the corresponding grooves 8 of the gate 6 or the gate frame 7. Specifically, the two sides of the back of the gate 6 are respectively provided with grooves 8 arranged vertically and the top is provided with a groove 8 arranged horizontally. The copper strip is embedded in the groove 8. The groove 8 adopts a dovetail groove structure. The reason for adopting the dovetail groove design is: (1) to enhance the structural stability. The dovetail groove structure has the characteristics of stable connection. The copper components are connected in the embedded design to form a strong overall structure, which can enhance the stability of the structure and make it more solid and durable; (2) to improve the sealing performance. The copper strip has good ductility and plasticity and can be tightly filled in the dovetail groove to form an effective seal. This sealing performance is crucial for preventing liquid leakage.
[0030] In some embodiments of this application, the roughness of the friction contact surface of the side sealing strip 1 and the friction contact surface of the top sealing strip 3 is less than or equal to 0.2 μm, and the flatness is less than or equal to 3 μm. By limiting the roughness and flatness of the copper strip contact surface, the copper strip has a good sealing effect and guiding effect after contact.
[0031] In some embodiments of this application, such as Figure 2 As shown, the side clamping mechanism 2 includes a first side wedge and a second side wedge. The first side wedge is installed on the gate 6, and the second side wedge is installed on the gate frame 7. In the direction from top to bottom, the contact surface between the first side wedge and the second side wedge is an inclined surface that is inclined towards the gate 6. The wedge structure makes the side sealing strip 1 form a locking structure during the closing process of the gate 6.
[0032] In some embodiments of this application, the front sides of the gate 6 are each connected vertically to two first side wedges that are spaced apart from each other. The gate frame 7 has a recessed structure on both sides. The inner wall of the recessed structure is connected to two second side wedges that are spaced apart from each other. The thickness of the lower first side wedge is less than the thickness of the upper first side wedge. The purpose of this design is to avoid interference between the lower first side wedge and the upper second side wedge during the upward movement of the upper first side wedge.
[0033] In some embodiments of this application, such as Figure 2 As shown, the top pressing mechanism 4 includes a first top wedge and a second top wedge. The first top wedge is installed on the gate 6 and the second top wedge is installed on the gate frame 7. In the direction from top to bottom, the contact surface of the first top wedge and the second top wedge is an inclined surface that is inclined away from the gate 6. The wedge structure makes the top sealing strip 3 form a locking structure during the closing process of the gate 6.
[0034] In some embodiments of this application, such as Figure 1 As shown, four brackets 9 are arranged horizontally at intervals on the top of the gate 6. The brackets 9 extend from the top of the gate 6 to the back of the gate 6. The first top wedge is connected to the bracket 9. The top of the gate frame 7 has an upward-opening recessed structure. The inner wall of the recessed structure is connected to the second top wedge corresponding to the first top wedge.
[0035] In some embodiments of this application, such as Figure 2 As shown, the bottom sealing strip 5 is made of rubber. The rubber strip has a connecting section and a sealing section. The connecting section is connected to the bottom of the gate 6 by bolts. The sealing section is set adjacent to the connecting section. Since the bottom sealing strip 5 and the bottom of the gate frame 7 are mainly pressed and sealed during the closing or opening of the gate 6, there is basically no friction process. Therefore, the elastic deformation of the rubber strip makes the bottom of the gate 6 and the bottom of the gate frame 7 form a good sealing structure.
[0036] During use, the copper strip serves as a guide and sealant for this type of quick-opening gate sealing structure, enabling the gate 6 to have a rapid opening and closing function and a good sealing effect. When the gate 6 is closed, the top pressing mechanism 4 applies pressure to the top sealing strip 3 to improve the sealing effect between the top of the gate 6 and the gate frame 7. The side pressing mechanism 2 applies pressure to the side sealing strip 1 to improve the sealing effect between the side of the gate and the gate frame 7. The bottom sealing strip 5 applies pressure to the bottom of the gate 6 to improve the sealing effect between the bottom edge of the gate and the gate frame 7, thus forming a good sealing structure around the gate 6 and the gate frame 7.

These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
