[0011] Compared with the prior art, the utility model has the following advantages: 1. During operation, the first sealing gasket can effectively prevent seawater from entering the motor through the motor output shaft, thereby preventing damage to the motor; the second sealing ring can effectively prevent seawater from entering the connecting base, thereby causing corrosion to the rotating screw and the extension rod in contact with seawater, thereby ensuring the service life.

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] An electric cylinder for deep sea environments, such as Figure 1-5 As shown, it includes a connecting base 1, a motor 2, a first sealing gasket 3, a flat belt 4, a rotating screw 5, a bearing 6, an extension rod 7, a second sealing ring 8 and a first fixing screw 9. The right part of the connecting base 1 is connected to the motor 2 by bolts. The motor 2 is a waterproof motor, and the casing is made of pressure-resistant and corrosion-resistant materials. The first sealing gasket 3 is connected between the motor 2 and the connecting base 1. A pulley is connected to the output shaft of the connecting base 1. The left part of the connecting base 1 is rotatably connected to the rotating screw 5 through the bearing 6. The lower side of the rotating screw 5 is also connected to a pulley. The pulleys are all located inside the connecting base 1. A flat belt 4 is wound around the pulleys. The outer side of the rotating screw 5 is connected to the extension rod 7 by a thread. The upper part of the extension rod 7 passes through the connecting base 1. The upper side of the connecting base 1 is connected to the second sealing ring 8 by the first fixing screw 9, and the upper part of the extension rod 7 passes through the second sealing ring 8.

[0026] When the device needs to be used, by starting the motor 2, the operation of the motor 2 will drive the right pulley to rotate, and then drive the left pulley to rotate through the flat belt 4, so that the rotating screw 5 rotates under the action of the bearing 6, and the rotation of the rotating screw 5 will drive the extension rod 7 to move upward through the thread, thereby achieving extension; during operation, the first sealing gasket 3 can effectively prevent seawater from entering the motor 2 through the output shaft of the motor 2, thereby avoiding damage to the motor 2, and the second sealing ring 8 can effectively prevent seawater from entering the connecting base 1, thereby causing corrosion to the rotating screw 5 and the extension rod 7 when in contact with seawater, thereby ensuring the service life.

[0027] like Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8As shown, it also includes a protective shell 10, a second fixing screw 11, a temperature controller 101, a heating tube 102 and a third sealing ring 12. The second fixing screw 11 is connected to the outer side of the base 1 and is connected to two front-to-back symmetrical protective shells 10. The side of the protective shells 10 close to each other is connected to a sealing strip. The upper part of the extension rod 7 passes through the protective shell 10. The lower parts of the protective shells 10 are connected with two left and right second fixing screws 11. The interior of the protective shell 10 is provided with a temperature controller 101. The interior of the protective shell 10 is provided with a heating tube 102. The temperature controller 101 and the heating tube 102 are electrically connected. The upper side of the protective shell 10 is connected to the third sealing ring 12. The upper part of the extension rod 7 passes through the third sealing ring 12.

[0028] The protective shell 10 can cover the connecting base 1 and the motor 2, so as to protect the motor 2 and the connecting base 1, so as to further prevent the internal parts of the device from contacting with seawater, causing corrosion and damage. The side of the protective shell 10 close to each other is connected with a sealing strip, so as to increase the sealing of the protective shell 10. The third sealing ring 12 can effectively prevent seawater from entering the protective shell 10 through the gap between the extension rod 7 and the protective shell 10. After the outer shell is damaged, a new protective shell 10 can be reinstalled and connected, thereby increasing the service life of the device; when the device is placed in the deep sea for use, the thermostat 101 can detect the temperature, and then control the heating tube 102 to operate for heating, thereby ensuring the normal operation of the internal parts and avoiding abnormal operation due to low temperature.

[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto.
