Description

Technical Field

[0001] The utility model relates to the technical field of drain valves, in particular to an electric drain valve. Background Art

[0002] On the drainage pipeline, electric drain valves will be installed in two adjacent groups of drainage pipes. The electric drain valves are used as regulating and intercepting devices. The electric drain valves are controlled by electric drivers, and the electric drivers are connected to the main power equipment through electrical wiring.

[0003] Existing, drainage pipelines are mainly buried underground, that is, installation pits are excavated on the ground, and drainage pipes and electric drainage valves are all arranged inside the installation pits. Therefore, it is inevitable that one end of the electric wiring will be buried in the installation pit, and part of the electric wiring will be suspended in the installation pit. For earthen installation pits, during the pit filling process, the soil will inevitably come into contact with the suspended electric wiring, causing the electric wiring to fall and shake under the action of external force, resulting in overall instability of the electric wiring. One end of the electric wiring will become loose and disconnected from the electric drive, affecting the stable operation of the electric drive, and then affecting the stable operation of the electric drainage valve. In view of the shortcomings of the existing technology, we propose an electric drainage valve to solve the above problems. Utility Model Content

[0029] 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 are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0030] An embodiment of the present application provides an electric drain valve to solve the problem that for an electric drain valve buried in an earthen installation pit, the electrical wiring connected to the electric driver may become disconnected from the electric driver under the influence of external forces, thereby affecting the stable operation of the electric driver and the electric drain valve, thereby achieving a stable connection between the electric driver and the electrical wiring.

[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0032] The embodiment of the utility model discloses an electric drain valve.

[0033] According to the attached Figure 1-6 As shown, it includes an electric drain valve body 1, a valve disc 11 rotatably arranged inside the electric drain valve body 1, a control rod 12 connected to the valve disc 11, and an electric driver 2 arranged on the top of the electric drain valve body 1. The outside of the electric driver 2 is provided with an electrical connection 3. The electric drain valve body 1, the valve disc 11, the control rod 12, the electric driver 2 and the electrical connection 3 constitute the electric drain valve. The electric drain valve can be used in a drainage pipeline. The electric driver 2 is connected to the main power control device through the electrical connection 3. The main power control device is not specifically drawn in the accompanying drawings. By turning on the electric driver 2, the control rod 12 connected to the electric driver 2 drives the valve disc 11 to rotate. When the valve disc 11 is opened, the drainage pipes in the drainage pipeline are in a connected state, so that the water can be discharged smoothly.

[0034] The outside of the electric drive 2 is provided with an anti-disconnection mechanism 4, which can increase the connection stability between one end of the electric wiring 3 and the electric drive 2, and prevent the electric wiring 3 from falling off at the electric drive 2. The anti-disconnection mechanism 4 includes a connection box 41, which is connected to the outside of the electric drive 2, and one side of the connection box 41 is rotatably connected to a box door 42. One side of the box door 42 is provided with a screw 47 for locking the box door 42 and the connection box 41. The connection box 41 cover is provided on the outside of the connection between the electric wiring 3 and the electric drive 2, and the opening and closing between the connection box 41 and the box door 42 is controlled by the screw 47. The first clamping block 44 and the second clamping block 45 are both provided inside the connection box 41, and one end of the electric wiring 3 is clamped between the first clamping block 44 and the second clamping block 45. Blocks 45, the outer walls of the first clamping block 44 and the second clamping block 45 are both provided with a rubber layer. The provided rubber layer can increase the stability of the electric wiring 3 between the first clamping block 44 and the second clamping block 45, and prevent the electric wiring 3 from sliding freely on the outer walls of the first clamping block 44 and the second clamping block 45. The end of the electric wiring 3 close to the electric drive 2 is clamped between the first clamping block 44 and the second clamping block 45, so that when the end of the electric wiring 3 outside the connection box 41 is subjected to external force, the part of the electric wiring 3 between the electric drive 2 and the two groups of clamping blocks will not be subjected to external force, so that the connection between the electric wiring 3 and the electric drive 2 is stable, and a through hole 7 is provided on one side of the box door 42, and one end of the electric wiring 3 extends to the outside of the connection box 41 through the through hole 7.

[0035] The threaded rod 46 is rotatably set inside the connecting box 41, and one end of the second clamping block 45 is threadedly sleeved on the outer wall of the threaded rod 46. The interior of the connecting box 41 is fixedly connected to the guide rail 43, and one end of the threaded rod 46 is rotatably set inside the guide rail 43. The first clamping block 44 is fixedly set on one side of the guide rail 43, and one end of the second clamping block 45 is slidably set inside the guide rail 43. By rotating the threaded rod 46, multiple groups of second clamping blocks 45 set on the outer wall of the threaded rod 46 can be driven to move up and down along the guide rail 43, and then the distance between an adjacent group of first clamping blocks 44 and second clamping blocks 45 can be adjusted, so that the electrical wires 3 of different diameters can be stably clamped between the first clamping block 44 and the second clamping block 45.

[0036] A fixing groove 5 is provided on one side of the connection box 41, and a locking assembly 6 is provided between the fixing groove 5 and the box door 42. That is, when the box door 42 is closed, the locking assembly 6 can be controlled at the same time to fix the threaded rod 46 inside the connection box 41, so as to prevent the threaded rod 46 and the second clamping block 45 threadedly connected to the outer wall of the threaded rod 46 from changing position, thereby ensuring that the first clamping block 44 and the second clamping block 45 can firmly clamp the electrical connection 3. The locking assembly 6 includes a toothed ring 61, and the outer wall of one end of the threaded rod 46 extending to the inside of the fixing groove 5 is fixedly connected to the toothed ring 61, and the toothed plate 6 2 is slidably arranged inside the fixed groove 5, one side of the tooth plate 62 is engaged with the outer wall of the gear ring 61, one end of the spherical rod 63 is fixedly connected to one side of the tooth plate 62, and the other end of the spherical rod 63 contacts one side of the box door 42. The spring 65 is arranged inside the fixed groove 5, one end of the spring 65 is against one side of the tooth plate 62, and the other end of the spring 65 is against the inner wall of the fixed groove 5. The interior of the fixed groove 5 is fixedly connected to the limit rod 64, one end of the tooth plate 62 is slidably arranged on the outer wall of the limit rod 64, and the spring 65 is sleeved on the outer wall of the limit rod 64. Figure 4 When the door 42 is fully closed, the toothed plate 62 is engaged with the toothed ring 61, and the door 42 is fixed to the connecting box 41 by the screw 47, thereby firmly engaging the toothed plate 62 with the toothed ring 61.
