Locking mechanism and filter device

Abstract

This utility model relates to the technical field of water conservancy engineering, specifically a locking mechanism and a filtering device. It includes an installation unit comprising at least two spaced-apart support frames and a connecting frame positioned between the support frames; and a filtering unit comprising a side plate positioned inside the support frames and a rotating rod rotatably positioned between the support frames. The advantages of this utility model are that the locking mechanism can be unlocked with a single button, and pulling the connecting handle and using spring energy to drive the debris-blocking net to rotate 90°, quickly completing the state switch. The vertical debris-blocking net maintains temporary interception, ensuring a high level of drainage capacity during cleaning. Manual entry into the ditch is unnecessary; cleaning can be performed by operating the debris-blocking box handle with a lifting device. In conjunction with the filtering unit, the debris-blocking net is fixed in a horizontal position by the locking mechanism, preventing it from simultaneously intercepting debris with the debris-blocking box. During cleaning, the debris-blocking net rotates 90° clockwise to stand upright, intercepting debris in the canal, while simultaneously rotating itself to a vertical interception position.

Description

Technical Field

[0001] This utility model relates to the technical field of water conservancy engineering, and in particular to a locking mechanism and a filtration device. Background Technology

[0002] In water conservancy projects, traditional trash racks intercept debris from flowing water using fixed frames. However, as operating time increases, they face two major drawbacks: after debris accumulates, manual entry into narrow channels is required for cleaning, which is inefficient and poses safety hazards, especially in deep water environments. Under high flow rates, cleaning is not safe, leading to continuous debris accumulation, which can cause water levels to rise or even overflow. Existing improvements, such as detachable trash racks, still rely on hoisting equipment for complete removal, which is time-consuming and results in the loss of interception function during cleaning, failing to meet flood control requirements. Utility Model Content

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] In view of the problems in the above or existing technologies, such as detachable trash racks that still rely on hoisting equipment for overall removal, which is time-consuming and loses its interception function during cleaning, thus failing to meet flood control requirements, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a locking mechanism.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an installation unit, including at least two spaced-apart support frames and a connecting frame disposed between the support frames; a filter unit, including a side plate disposed inside the support frames, a rotating rod rotatably disposed between the support frames, a dirt-blocking net disposed on the rotating rod, and a locking member disposed at one end of the rotating rod and cooperating with one of the support frames.

[0007] As a preferred embodiment of the locking mechanism of this utility model, the support frame has an installation groove on its outer side, and the support frame and the connecting frame each have corresponding installation holes. The two ends of the connecting frame are respectively placed in the installation grooves of the corresponding support frame, and the installation holes on the connecting frame and the support frame are aligned. Bolts are movably connected in the installation holes.

[0008] As a preferred embodiment of the locking mechanism of this utility model, the locking member includes a reset groove opened at one end of the rotating rod, a connecting handle slidably disposed in the reset groove, a spring disposed in the reset groove and connected to the connecting handle, and a locking block disposed on the outside of the connecting handle.

[0009] As a preferred embodiment of the locking mechanism of this utility model, a slot is formed on the outside of the support frame corresponding to one end of the rotating rod;

[0010] The card blocks mate with the mounting slot and the card slot, respectively.

[0011] In a preferred embodiment of the locking mechanism of this utility model, a rectangular groove is provided at the bottom of the inner wall of the reset groove, and a transmission rod is provided at one end of the connecting handle facing the bottom of the reset groove. The transmission rod extends into the rectangular groove and its cross-sectional shape is adapted to the rectangular groove.

[0012] In a preferred embodiment of the locking mechanism of this utility model, the length of the transmission rod is less than the length of the rectangular groove.

[0013] The locking mechanism of this utility model has the following advantages: the locking mechanism can be unlocked with one click, and pulling the connecting handle and the spring energy storage can drive the debris screen to rotate 90°, quickly completing the state switch. The vertical debris screen maintains temporary interception, and the drainage capacity remains at a high level during cleaning.

[0014] In actual use, there are still problems such as the need for manual entry into narrow channels to work after garbage accumulates, which is inefficient and poses safety hazards.

[0015] To solve the above-mentioned technical problems, the present invention also provides the following technical solution: a cleaning unit, including a dirt-blocking box and a base plate disposed between support frames, wherein the dirt-blocking box is disposed on the base plate.

[0016] As a preferred embodiment of the filtration device of this utility model, the front side of the debris box is provided with a water inlet, and the rear side is arranged with a plurality of water outlets in an array along the length direction.

[0017] In a preferred embodiment of the filtration device of this utility model, the baffle strip disposed on the inner side of the support frame extends parallel to the plane of the debris box, and the length direction of the baffle strip is consistent with the side direction of the debris box.

[0018] As a preferred embodiment of the filtration device of this utility model, a handle is provided on the upper part of the dirt-blocking box.

[0019] The beneficial effects of this utility model are: no need for manual ditching; cleaning can be carried out by operating the handle of the debris-blocking box with a hoist. With the filter unit, the debris-blocking net is fixed in a horizontal position by a locking mechanism, so it does not intercept garbage at the same time as the debris-blocking box. During cleaning, the debris-blocking net rotates 90° clockwise to stand upright, intercepting garbage in the river and canal, while at the same time it turns into a vertical interception position.

[0031] Example 1

[0032] Reference Figures 1 to 6 This is the first embodiment of the present invention, which provides a locking mechanism mainly used in the scenario of garbage interception and cleaning in the drainage ditch of a hydropower station. The device consists of a locking mechanism and...

[0033] The debris-blocking box 31 is composed of a locking mechanism that enables rapid angle adjustment and fixation of the debris-blocking net 23; the debris-blocking box 31 serves as the main interception unit and works in conjunction with the locking mechanism to achieve debris cleaning, including an installation unit 1, which includes at least two spaced support frames 11 and a connecting frame 12 disposed between the support frames 11;

[0034] Cleaning unit 3 includes a side plate 21 disposed inside the support frame 11, a rotating rod 22 rotatably disposed between the support frames 11, a dirt-blocking net 23 disposed on the rotating rod 22, and a locking member 24 disposed at one end of the rotating rod 22 and cooperating with one of the support frames 11.

[0035] The mounting unit 1 consists of two parallel support frames 11 and a connecting frame 12. The support frames 11 have mounting grooves 13 on their outer sides, and the two ends of the connecting frame 12 are embedded in the grooves and fixed by bolts 15 through aligned mounting holes 14.

[0036] The rotating rod 22 is placed horizontally between the two support frames 11, with one end extending to the outside of the support frame 11. The debris net 23 is fixed on the rotating rod 22. In its initial state, it is parallel to the ground and does not filter the river channel.

[0037] The locking element 24 is integrated into the end of the rotating rod 22, including a reset groove 241 opened at one end of the rotating rod 22, a connecting handle 242 slidably disposed in the reset groove 241, a spring 243 disposed in the reset groove 241 and connected to the connecting handle 242, and a locking block 244 disposed on the outside of the connecting handle 242. The reset groove 241 is opened at the end of the rotating rod 22, and the connecting handle 242 is slidably disposed in the reset groove 241.

[0038] Spring 243 connects the bottom of reset groove 241 to connecting handle 242, and locking block 244 is vertically fixed to the outside of connecting handle 242. Locking groove 245 is opened on the outer wall of support frame 11 on the same side as rotating rod 22 for locking block 244.

[0039] The inner wall of the reset groove 241 is provided with a rectangular groove 246, and the bottom of the connecting handle 242 is provided with a transmission rod 247. Its cross-section matches the rectangular groove 246 and its length is less than the groove depth. When the transmission rod 247 slides in the rectangular groove 246, it restricts the rotation angle of the connecting handle 242, ensuring that the debris net 23 can only rotate within the range of 0°-90°. The bottom plate 32 fits the bottom of the drainage ditch, and impermeable side plates 21 are provided on both sides to form a water flow channel. The front side is provided with a water inlet 33, and the rear side is provided with an array of water outlet grooves 34. The top is provided with a handle 36 for easy hoisting.

[0040] The debris-blocking box 31 is placed on the base plate 32. The head of the base plate 32 is an arc-shaped guide surface to reduce the accumulation of garbage. A baffle is added to the inner side of the support frame 11. Its extension direction is parallel to the plane of the debris-blocking box 31 to limit the displacement of the box.

[0041] In the initial debris-blocking state, the locking block 244 is embedded in the locking slot 245, the rotating rod 22 is fixed, and the debris-blocking net 23 is in a horizontal position, not intercepting water and debris together with the debris-blocking box 31. When debris overflows from the debris-blocking box 31, it needs to be cleaned. The connecting handle 242 can be pulled outward to compress the spring 243, causing the locking block 244 to disengage from the locking slot 245. The transmission rod 247 slides along the rectangular groove 246, ensuring that the connecting handle 242 only moves linearly and does not rotate. Rotating the connecting handle 242 clockwise by 90° will rotate the rod 244. 2. Drive the debris barrier 23 to the vertical position. The vertical debris barrier 23 continues to intercept newly flowing garbage. Release the connecting handle 242. The spring 243 pushes the locking block 244 to reset. The locking block 244 is embedded in the mounting groove 13 to achieve vertical locking. At this time, the fluid in the canal begins to filter garbage through the debris barrier 23. Lift the debris barrier box 31 through the lifting handle 36. After dumping the garbage, reset it and restore the debris barrier box 31. Reverse the operation to rotate the rod 22 to the horizontal position. The locking block 244 pops into the locking groove 245 to complete the fixation.

[0042] The locking mechanism enables the 2390° one-click rotation of the debris barrier net, avoiding manual ditch work. The upright debris barrier net 23 maintains the temporary interception function. The transmission rod 247 and rectangular groove 246 are designed to limit the rotation angle and prevent excessive rotation from damaging the mechanism.
