Description

Technical Field

[0001] This invention belongs to the technical field of sewage treatment equipment, specifically relating to a non-clogging sewage discharge valve device and a sewage suction truck. Background Technology

[0002] Currently, the discharge valve of a septic tank truck is usually installed on the top of the tank and is manually operated. During the use of the septic tank truck, the operator needs to climb onto the tank to operate the discharge valve, which is very inconvenient. In addition, during winter operation, the surface of the tank will freeze and frost, which increases the danger to the operator.

[0003] Patent CN222452061U discloses a sewage suction and purification vehicle with a rotating opening mechanism for the top cover. The opening and closing of the sewage discharge top cover can be achieved by remotely controlling the hydraulic rotating opening cylinder through a hydraulic multi-way valve. However, this strategy has a complex hydraulic system and high installation and maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a non-clogging manure discharge valve device and a manure suction truck. This invention employs both manual and automatic operation modes, featuring a simple structure, high transmission efficiency, and low manufacturing cost.

[0005] This invention provides the following technical solution: In a first aspect, a non-clogging manure discharge valve device is provided, comprising a housing assembly, a valve body, a first transmission component, an electric mechanism, and a manual mechanism; The housing assembly and the electric mechanism are mounted on the tank body; The valve body includes a lead screw, one end of which is connected to a valve plug for sealing the drain port of the tank, and the other end is installed through the housing assembly; The first transmission component is installed inside the housing assembly and sleeved on the lead screw. The output end of the electric mechanism extends into the housing assembly and is geared with the first transmission component. One end of the manual mechanism is installed outside the housing assembly, and the other end extends into the housing assembly and is geared with the first transmission component.

[0006] Furthermore, the housing assembly includes an end cap, a housing, an opening flange, and a first support member. The end cap is fixed to the top of the housing. The housing includes a first housing and a second housing. The first housing is mounted on the second housing, and the second housing is fixed to the tank body. The opening flange is mounted at the interface between the first housing and the second housing. The first support member is mounted between the first housing and the second housing, and the first support member is fixed to the housing and the opening flange by bolts.

[0007] Furthermore, the valve body also includes an end sleeve and a sleeve. The sleeve is disposed inside the tank and is installed on the first support member through the end sleeve. One end of the lead screw passes through the sleeve, the first support member, the end sleeve, the first transmission member and the end cover in sequence and extends out of the housing. The other end is connected to the valve plug, which is installed at the drain port of the tank.

[0008] Furthermore, the outer wall of the lead screw is provided with a groove, the end sleeve is provided with a first convex ridge structure, and the end cap is provided with a second convex ridge structure. The groove fits into the first convex ridge structure and the second convex ridge structure.

[0009] Furthermore, the first transmission component is installed between the end cover and the end sleeve, and a planar thrust ball bearing is provided between the first transmission component and the end cover and between the first transmission component and the end sleeve, and the planar thrust ball bearing is sleeved on the lead screw.

[0010] Furthermore, the first transmission component is provided with an internal threaded hole, and the outer wall of the lead screw is provided with threads, and the first transmission component is threadedly connected to the lead screw.

[0011] Furthermore, the output end of the electric mechanism is provided with a second transmission component, and the end of the manual mechanism is provided with a third transmission component.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention has two operating modes: manual and automatic. Through gear transmission, the transmission efficiency is high and it is suitable for the occurrence of emergencies. When the electric mechanism is started, the first transmission component is driven to rotate through gear transmission, and the lead screw is driven to move up and down to efficiently realize the opening and closing of the sewage outlet. At the same time, in the event of an emergency, the first transmission component can be manually driven to rotate, and the lead screw can be driven to move up and down to realize the opening and closing of the sewage outlet.

[0022] Example 1

[0023] This embodiment provides a non-clogging manure discharge valve device, including a housing assembly, a valve body 11, a first transmission component 5, an electric mechanism 6, and a manual mechanism 10.

[0024] like Figure 1 and Figure 2 As shown, the shell assembly is mounted on the tank 14. The shell assembly includes an end cap 3, a shell 4, an opening flange 13, and a first support member 16. The end cap 3 is fixed to the top of the shell 4. In this embodiment, the shell 4 includes a first shell and a second shell. The first shell is mounted on the second shell, and the second shell is welded to the tank 14. The opening flange 13 is mounted on the two side walls of the shell 4, i.e., at the interface where the first shell and the second shell contact each other. The first support member 16 passes through the shell 4 and is installed between the first shell and the second shell. The first support member 16, the shell 4, and the opening flange 13 are fixed by bolts, and the shell 4 encloses the internal parts.

[0025] The valve body 11 includes a lead screw 2, an end sleeve 8, a valve plug 12, and a sleeve 15. The sleeve 15 is vertically disposed inside the tank body 14 and is mounted on the first support member 16 via the end sleeve 8. In this embodiment, the end sleeve 8 and the first support member 16 are fixed by bolts. The lead screw 2 passes vertically through and is mounted on the tank body 14 and the shell 4. One end of the lead screw 2 passes sequentially through the sleeve 15, the first support member 16, the end sleeve 8, the first transmission member 5, and the end cap 3, and extends out of the top of the shell 4. The other end is connected to the valve plug 12, which is installed at the drain port of the tank body 14. The movement of the lead screw 2 drives the valve plug 12 to move away from and contact the drain port, thereby opening or closing the drain port of the tank body.

[0026] like Figure 3 and Figure 4As shown, the outer wall of the lead screw 2 is provided with a groove 17, the end sleeve 8 is provided with a first protruding ridge structure, and the end cap 3 is provided with a second protruding ridge structure. The first and second protruding ridge structures can be precisely engaged in the groove 17. Through the cooperation of the groove 17 with the first and second protruding ridge structures, the rotational movement of the lead screw 2 in the horizontal direction can be restricted, so that the lead screw 2 only performs linear movement in the vertical direction. In some possible embodiments, the outer wall of the lead screw 2 is provided with a long groove with a length × depth × width of 180mm × 3mm × 5mm, and the dimensions of the first and second protruding ridge structures are both 3mm × 5mm.

[0027] like Figure 5 and Figure 6 As shown, the first transmission component 5 is installed between the end cover 3 and the end sleeve 8. A planar thrust ball bearing 1 is provided at the top of the first transmission component 5, i.e., between it and the end cover 3, and at the bottom of the first transmission component 5, i.e., between it and the end sleeve 8. The planar thrust ball bearing 1 is sleeved on the lead screw 2. On the one hand, it can reduce the friction between the first transmission component 5 and the end cover 3 and the end sleeve 8; on the other hand, it can ensure the stable rotation of the first transmission component 5. The first transmission component 5 has an internal threaded hole, and the outer wall of the lead screw 2 also has threads. The first transmission component 5 is connected to the lead screw 2 through the threads.

[0028] like Figure 1 and Figure 5As shown, the electric mechanism 6 is mounted on the tank 14 and located outside the shell 4. The output end of the electric mechanism 6 extends into the interior of the shell 4 through the side of the shell 4. The output end of the electric mechanism 6 is provided with a second transmission component 7, which meshes with the first transmission component 5 and is driven by gears. When the electric mechanism 6 is turned on, its power is transmitted to the first transmission component 5 through the second transmission component 7 at the output end, driving the first transmission component 5 to rotate around the lead screw. The manual mechanism 10 is fixed to the outside of the shell 4, and its end extends into the interior of the shell. Its end is provided with a third transmission component 9, which meshes with the first transmission component 5 by gears. When the electric mechanism 6 encounters a special situation, the manual mechanism 10 can be manually activated to realize the normal operation of the manure discharge valve. In this embodiment, there are no special requirements for the installation position of the electric mechanism 6 and the manual mechanism 10, ensuring that they work independently without interference. In this embodiment, the installation positions of the electric mechanism 6 and the manual mechanism 10 are relatively perpendicular, and the axes of the second transmission component 7 and the third transmission component 9 are perpendicular to each other. The electric mechanism 6 is equipped with a locking circuit. When the manure discharge valve is not working, the locking circuit on the electric mechanism 6 is activated, causing the second transmission component 7 to mesh with the first transmission component 5 and fix the first transmission component 5, thereby fixing the lead screw 2 and preventing the lead screw 2 from being disturbed by external factors and moving up and down, ensuring that the valve plug 12 is closed at the sewage outlet of the tank 14. When it is necessary to activate the manual mechanism 10, the locking circuit on the electric mechanism 6 is closed to ensure that the first transmission component 5 can rotate relative to the lead screw 2.

[0029] In this embodiment, the first transmission component 5, the second transmission component 7, and the third transmission component 9 are all helical gears, the manual mechanism 10 is a hand crank, and the electric mechanism 6 is any one of an electric motor or a hydraulic motor. In some possible embodiments, the first transmission component 5 is a gear or a worm gear, and the second transmission component 7 and the third transmission component 9 are racks or worm gears. Through the engagement of the gear and rack or the engagement of the worm gear and the worm gear, the first transmission component 5 achieves gear transmission with the second transmission component 7 and the third transmission component 9, respectively.

[0030] The main working principle of this embodiment is as follows: When the sewage outlet of tank 14 needs to be opened, the sewage valve starts working, activating the electric mechanism 6. The electric mechanism 6 transmits power to its output end, driving the second transmission component 7 to rotate. Through gear meshing, the power is transmitted to the first transmission component 5, which then rotates and drives the lead screw 2 to move. Since the groove 17 of the lead screw 2 matches the first convex structure of the end cover 3 and the second convex structure of the end sleeve 8, the horizontal rotation of the lead screw 2 is restricted. Therefore, under the power drive of the first transmission component 5, the lead screw 2 moves up and down in the vertical direction, driving the valve plug 12 to move up and down, ultimately opening or closing the sewage outlet of tank 14. Simultaneously, this invention includes a manual mechanism 10. In special circumstances, the manual mechanism drives the third transmission component 9 to move, which in turn drives the first transmission component 5 to rotate, thereby causing the lead screw 2 to move up and down in the vertical direction, ultimately opening or closing the sewage outlet of tank 14.

[0031] Example 2

[0032] This embodiment provides a sewage suction truck based on the non-clogging sewage discharge valve device provided in Embodiment 1, including a vehicle body, a tank 14, and the non-clogging sewage discharge valve device provided in Embodiment 1.

[0033] The non-clogging manure discharge valve device is installed on the tank 14, and the tank 14 is installed on the vehicle body.

[0034] When the vehicle is in motion or the manure discharge valve is not working, the locking circuit of the electric mechanism 6 is activated, and the lead screw 2 is locked, preventing the lead screw 2 and the first transmission component 5 from moving relative to each other due to external force.

[0035] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
