Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to an automatic regulating and tightening device for a gate water seal. Background Art

[0002] Gates are control facilities used to close and open drainage channels. They are essential components of hydraulic structures, serving to intercept water flow, control water levels, regulate flow, and discharge sediment and floating debris. Water seals are components installed around the gates, creating a seal by compressing and deforming against the structure. These components are crucial to the gate, and their condition directly impacts their water-stopping effectiveness.

[0003] Traditional water seal Figure 2 As shown in the figure, the water seal is fixed to the gate by bolts, and the water seal head is pressed against the wall and deformed by squeezing, thereby playing the role of sealing and water stopping. However, due to the uneven working surface of some types of water seals (L-type, P-type, etc.), the water seal will show aging wear and plastic deformation during long-term use, resulting in a decrease in the sealing and water-stopping effect of the water seal.

[0004] The Chinese utility model patent with publication number CN209368795U discloses a water seal adjustment and tightening device for a gate, in which an L-shaped steel plate is installed on the upper layer of the water seal pressure plate, and screw holes are provided on the L-shaped steel plate for installing a tightening bolt. The head of the tightening bolt abuts against the water seal head of the water seal, and the tightening bolt can be screwed in and out of the screw hole of the L-shaped steel plate. The more the tightening bolt is screwed in toward the water seal head, the tighter the water seal head is attached to the wall. In this way, after the water seal is aged, worn, and plastically deformed, the water seal head can be tightly fitted to the wall again, thereby restoring the sealing effect of the water seal. However, the above scheme only prolongs the effective water-stopping time of the water seal to a certain extent, and requires manual adjustment of the tightening bolt. However, once the gate is in service, most of the water seal is immersed in water. If the tightening bolt is to be adjusted, diving operation is required, which has high operation cost and great risk. Utility Model Content

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] Example 1

[0024] Figure 1 This is a schematic diagram of the structure of a gate water seal automatic adjustment and tightening device provided by the embodiment of the utility model. Figure 1 As shown, the gate water seal automatic adjustment and tightening device includes a base plate 1 and a tightening plate 2. The base plate 1 is connected to the top of the water seal pressure plate. In one possible implementation, the base plate 1 has a through hole 103, and is fixedly connected to the water seal pressure plate via a fixing bolt passing through the through hole 103. In addition, a transition layer, such as a gasket, can be provided between the base plate 1 and the water seal pressure plate, which will not be detailed here.

[0025] Specifically, a first side panel 101 and a second side panel 102 are respectively provided on opposite sides of the seat plate 1. The first side panel 101 is provided on the side of the water seal head of the seat plate 1 close to the rubber water seal, and the tightening plate 2 is provided on the outer side of the first side panel 101. In one possible implementation method, the cross-section of the seat plate 1 is "U"-shaped. In addition, it can also be other shapes such as "mouth" shape, which is not specifically limited here.

[0026] A clamping rod 3 is installed on the seat plate 1, and the clamping rod 3 consists of a first segment 301 set through the first side plate 101 and a second segment 302 connected to the first segment 301; a spring 303 and a slider 304 are sleeved on the second segment 302, wherein the slider 304 is held between the first side plate 101 and the second side plate 102, and the first end of the first segment 301 is connected to the clamping plate 2 for pushing the clamping plate 2; the first end of the spring 303 abuts the second end of the first segment 301, and the second end of the spring 303 abuts the slider 304; the slider 304 can be optionally fixed on the seat plate 1, and when the gate water seal automatic adjustment and tightening device is installed, the spring 303 is pre-compressed on the second segment 302, and the end of the second segment 302 away from the first segment 301 is set through the slider 304.

[0027] Based on the above arrangement, when the water seal compression force changes due to aging, wear, plastic deformation, etc., the spring 303 will push the first segment 301 toward the water seal head through the pre-compressed elastic force, thereby realizing automatic compensation of the compression force, so that the water seal head and the wall are always kept in a compressed state, providing sufficient compression force for the water seal head and the wall, and ensuring a good water-stopping effect of the water seal; in addition, through automatic compensation, no manual adjustment is required after installation, which can also reduce operation and maintenance costs and risks.

[0028] Example 2

[0029] This embodiment is based on the technical solution provided in Example 1, and further describes the structure of the pressing rod 3:

[0030] In this embodiment, the first segment 301 is in a "trident" shape to improve stability; the first side plate 101 is provided with three through holes corresponding to the first segment 301, and each head end of the "trident"-shaped first segment 301 passes through the corresponding through holes on the first side plate 101 and is connected to the tightening plate 2; in addition, the first segment 301 can also be other structures, such as a single rod, multiple rods, etc., which are not specifically limited here.

[0031] The end of the second segment 302 away from the first segment 301 is arranged to pass through the second side plate 102. The head end of the second segment 302 passing through the second side plate 102 is provided with a boss 305 to limit the displacement of the second segment 302 toward the water seal head. In this embodiment, the slider 304 can be optionally slidably arranged on the seat plate 1. The side of the slider 304 close to the second side plate 102 is connected to a guide rod 306. The guide rod 306 is arranged to pass through the second side plate 102 to limit the displacement of the slider 304 and improve the stability of the slider 304. Specifically, the end of the guide rod 306 is provided with an internal thread, and the first end of the guide rod 306 is threadedly engaged with the slider 304. Two guide rods 306 are connected to the side of the slider 304 close to the second side plate 102, and the two guide rods 306 are respectively arranged on both sides of the second segment 302.

[0032] Example 3

[0033] This embodiment, based on the technical solution provided in Example 2, provides a solution for manually adjusting the pressing force:

[0034] In this embodiment, a support frame 4 is connected to the outer side of the second side plate 102. In this embodiment, the support frame 4 is "U"-shaped in a top view, and its two free ends are connected to the second side plate 102; a threaded hole is provided on the support frame 4, and an adjusting bolt 401 is threadedly engaged with the inner thread of the threaded hole. The first end of the adjusting bolt 401 is connected to the guide rod 306, and the second end of the adjusting bolt 401 is threadedly engaged with a back-tightening nut 402, and the clamping force can be manually adjusted by the adjusting bolt 401.

[0035] In one implementation of this embodiment, two threaded holes are opened on the support frame 4 corresponding to the two guide rods 306, the second end of the guide rod 306 is threadedly engaged with the adjusting bolt 401, and the thread directions of the first end and the second end of the guide rod 306 are opposite.

[0036] When the adjusting screw 401 is rotated in the opposite direction, the guide rod 306 is driven to rotate in the opposite direction, and the threaded section of the slider 304 that is threadedly engaged with the first end of the guide rod 306 is screwed out of the internal thread of the first end of the guide rod 306, thereby converting the rotational motion of the guide rod 306 into a linear motion, which is displaced in the direction of the water seal head and compresses the spring 303 to adjust the clamping force of the spring 303. After the adjustment is completed, the adjusting screw 401 is further limited by the back-tightening nut 402. On the contrary, when the adjusting screw 401 is rotated in the opposite direction, the guide rod 306 is driven to rotate in the opposite direction, and the threaded section of the slider 304 that is threadedly engaged with the first end of the guide rod 306 is screwed into the internal thread of the first end of the guide rod 306, thereby driving the slider 304 to move in the opposite direction of the water seal head and releasing the clamping force on the spring 303.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
