DETAILED DESCRIPTION

[0030] The utility model is further described in detail below with reference to the accompanying drawings and specific implementation methods:

[0031] This embodiment aims to provide a concrete torpedo tank cleaning device, which is mainly used for cleaning concrete torpedo tanks, and addresses the problem that traditional torpedo tank cleaning equipment cannot perform comprehensive and thorough cleaning and is time-consuming and labor-intensive.

[0032] A concrete torpedo tank cleaning device, such as Figure 1, including an electric lifting rod 1, a rotating mechanism and a water spraying mechanism; the rotating mechanism includes a transmission box 2, a driving shaft 3, a driven shaft 4 and a driving motor 5; the transmission box 2 is hoisted on the ceiling of the workshop through the electric lifting rod 1 and is located above the torpedo tank track; this embodiment adopts a hydraulic telescopic rod and calls the workshop control system for control. The electric lifting rod 1 is mainly used to realize and control the up and down movement of the cleaning device. Its specific structure is the prior art and has been used in this field, so it will not be repeated here; the transmission box 2 is located above the torpedo tank track. When the torpedo tank is docked at the corresponding position, the water spraying head 10 can pass through the material port of the torpedo tank through the electric lifting rod 1 and enter the inside of the torpedo tank.

[0033] The driving shaft 3 and the driven shaft 4 are both rotatably arranged in the transmission box 2 and are connected through the transmission mechanism 6; Figure 3 The upper end of the driving shaft 3 is connected to the driving motor 5, the driving motor 5 is located in the transmission box 2 and fixed on the upper box wall of the transmission box 2, and the lower ends of the driving shaft 3 and the driven shaft 4 are rotatably arranged in the bottom of the transmission box 2 through the bearing 12, as shown in FIG. Figure 4 The driven shaft 4 has a water-passing cavity 401 which runs through from top to bottom and is used to convey water. The lower end of the driven shaft 4 extends out of the transmission box 2 and is connected to the water pipe 9 through a straight joint 11. The function of the straight joint 11 is similar to that of a coupling to coaxially connect the driven shaft 4 and the water pipe 9, but at the same time it can connect the waterway and prevent water leakage.

[0034] In order to improve the compactness of the structure and reduce the size of the transmission box 2, the driving shaft 3 and the driven shaft 4 in this embodiment are transmitted through a gear mechanism. The transmission mechanism 6 includes a driving gear 601 and a driven gear 602. The driving gear 601 is installed on the driving shaft 3, and the driven gear 602 is installed on the driven shaft 4 and meshes with the driving gear 601. Since the rotation is low-speed and there is no transmission accuracy requirement, in other embodiments, the transmission connection method can also be belt drive or chain drive.

[0035] The water spraying mechanism includes a water inlet pipe 7, a rotating joint 8, a water pipe 9 and a water spraying head 10; Figure 2 and Figure 3 The rotary joint 8 includes a fixed part 801 and a rotating part 802 that are rotatably connected. The transmission part is rotatably mounted in the fixed part 801. When the fixed part 801 is fixed, the rotating part 802 can rotate by itself without leaking. The rotary nozzle is a prior art, mainly used to eliminate the transmission of torque, and has been used in the field of water pipe installation. Its specific structure will not be described in detail; Figure 3The fixed part 801 is vertically clamped and fixed on the upper box wall of the transmission box 2, and extends upward from the transmission box 2. The upper end of the fixed part 801 is connected with a water inlet pipe 7. The rotating part 802 is fixedly sleeved on the upper end of the transmission shaft and is connected with the water passage chamber 401; the water passage pipe 9 is transmission-connected with the driven shaft 4 and is connected with the water passage chamber 401. The water passage pipe 9 extends vertically downward, and a water spray head 10 is vertically installed at its end; in order to further improve the coverage of the water spray head 10, the water outlet of the water spray head 10 is a vertically arranged flat fan-shaped, thereby expanding the coverage in the up and down directions and improving the cleaning efficiency.

[0036] In this embodiment, the water pipe 9 is a hard water pipe, and the water pipe 9, the driven shaft 4 and the rotary joint 8 are arranged coaxially to help improve the stability of the system, reduce the instability and vibration caused by the rotational motion, and reduce space occupancy.

[0037] The usage process of this example is as follows: the torpedo tank is correspondingly docked below the cleaning device with its feed opening facing upwards; the electric lifting rod 1 operates, the cleaning device is lowered as a whole, and the water spray head 10 enters the torpedo tank through the feed opening; water is passed through the water inlet pipe 7, the water path passes through the water inlet pipe 7, the driven shaft 4 and the water pipe 9, and is sprayed out from the water spray head 10; at the same time, the driving motor 5 works, and the driven shaft 4 is rotated through the transmission mechanism 6, thereby driving the water pipe 9 and the water spray head 10 to rotate, so that the water spray head 10 sprays water 360 degrees, and combined with the up and down movement of the electric lifting rod 1, the side walls around the torpedo tank are washed in all directions; after the washing is completed, the cleaning device is retracted upwards, the torpedo tank is turned over, the feed opening is facing downwards and the dirty water is poured out; the above washing steps are repeated until the ideal cleaning effect is achieved.

[0038] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that the hoisting structure is optimized to address the problem that the length requirement of the electric lifting rod 1 is too high due to a high ceiling.

[0039] like Figure 5 This embodiment uses two sets of electric lifting rods 1. The transmission box is a rectangular box. The two sets of electric lifting rods 1 are vertically fixed at two diagonal positions on the upper surface of the transmission box. The two sets of electric lifting rods 1 move synchronously, and the remaining two diagonal positions are fixed with ordinary telescopic rods. The telescopic rods do not have driving ability and only follow the electric lifting rods 1 to perform up and down telescopic movements to reduce the number of deployed electric lifting rods 1. By fixing and hoisting the four corners of the transmission box, compared with single-point fixing, it can better resist the influence of high wind and other factors and has better stability.

[0040] The upper part of the electric lifting rod 1 and the telescopic rod is fixedly connected with a mounting plate, on which a mounting frame 13 is fixedly mounted. The mounting frame 13 adopts a truss structure, and the mounting frame 13 is vertically fixed on a ceiling or other fixed foundation such as a beam. It is mainly used to solve the problem that the length requirement of the electric lifting rod 1 is higher when the fixed foundation such as the ceiling is higher.
